Hmmm you can find lot of examples for configuring spring framework. Anyways here is a sample

@Configuration
@Import({PersistenceConfig.class})
@ComponentScan(basePackageClasses = { 
    ServiceMarker.class,
    RepositoryMarker.class }
)
public class AppConfig {

}

PersistenceConfig

@Configuration
@PropertySource(value = { "classpath:database/jdbc.properties" })
@EnableTransactionManagement
public class PersistenceConfig {

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
    private static final String PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH = "hibernate.max_fetch_depth";
    private static final String PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE = "hibernate.jdbc.fetch_size";
    private static final String PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE = "hibernate.jdbc.batch_size";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";
    private static final String[] ENTITYMANAGER_PACKAGES_TO_SCAN = {"a.b.c.entities", "a.b.c.converters"};

    @Autowired
    private Environment env;

     @Bean(destroyMethod = "close")
     public DataSource dataSource() {
         BasicDataSource dataSource = new BasicDataSource();
         dataSource.setDriverClassName(env.getProperty("jdbc.driverClassName"));
         dataSource.setUrl(env.getProperty("jdbc.url"));
         dataSource.setUsername(env.getProperty("jdbc.username"));
         dataSource.setPassword(env.getProperty("jdbc.password"));
         return dataSource;
     }

     @Bean
     public JpaTransactionManager jpaTransactionManager() {
         JpaTransactionManager transactionManager = new JpaTransactionManager();
         transactionManager.setEntityManagerFactory(entityManagerFactoryBean().getObject());
         return transactionManager;
     }

    private HibernateJpaVendorAdapter vendorAdaptor() {
         HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
         vendorAdapter.setShowSql(true);
         return vendorAdapter;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean() {

         LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();
         entityManagerFactoryBean.setJpaVendorAdapter(vendorAdaptor());
         entityManagerFactoryBean.setDataSource(dataSource());
         entityManagerFactoryBean.setPersistenceProviderClass(HibernatePersistenceProvider.class);
         entityManagerFactoryBean.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);             
         entityManagerFactoryBean.setJpaProperties(jpaHibernateProperties());

         return entityManagerFactoryBean;
     }

     private Properties jpaHibernateProperties() {

         Properties properties = new Properties();

         properties.put(PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH, env.getProperty(PROPERTY_NAME_HIBERNATE_MAX_FETCH_DEPTH));
         properties.put(PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE, env.getProperty(PROPERTY_NAME_HIBERNATE_JDBC_FETCH_SIZE));
         properties.put(PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE, env.getProperty(PROPERTY_NAME_HIBERNATE_JDBC_BATCH_SIZE));
         properties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, env.getProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));

Main

public static void main(String[] args) { 
    try (GenericApplicationContext springContext = new AnnotationConfigApplicationContext(AppConfig.class)) {
        MyService myService = springContext.getBean(MyServiceImpl.class);
        try {
            myService.handleProcess(fromDate, toDate);
        } catch (Exception e) {
            logger.error("Exception occurs", e);
            myService.handleException(fromDate, toDate, e);
        }
    } catch (Exception e) {
        logger.error("Exception occurs in loading Spring context: ", e);
    }
}

MyService

@Service
public class MyServiceImpl implements MyService {

    @Inject
    private MyDao myDao;

    @Override
    public void handleProcess(String fromDate, String toDate) {
        List<Student> myList = myDao.select(fromDate, toDate);
    }
}

MyDaoImpl

@Repository
@Transactional
public class MyDaoImpl implements MyDao {

    @PersistenceContext
    private EntityManager entityManager;

    public Student select(String fromDate, String toDate){

        TypedQuery<Student> query = entityManager.createNamedQuery("Student.findByKey", Student.class);
        query.setParameter("fromDate", fromDate);
        query.setParameter("toDate", toDate);
        List<Student> list = query.getResultList();
        return CollectionUtils.isEmpty(list) ? null : list;
    }

}

Assuming maven project: Properties file should be in src/main/resources/database folder

jdbc.properties file

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=your db url
jdbc.username=your Username
jdbc.password=Your password

hibernate.max_fetch_depth = 3
hibernate.jdbc.fetch_size = 50
hibernate.jdbc.batch_size = 10
hibernate.show_sql = true

ServiceMarker and RepositoryMarker are just empty interfaces in your service or repository impl package.

Let's say you have package name a.b.c.service.impl. MyServiceImpl is in this package and so is ServiceMarker.

public interface ServiceMarker {

}

Same for repository marker. Let's say you have a.b.c.repository.impl or a.b.c.dao.impl package name. Then MyDaoImpl is in this this package and also Repositorymarker

public interface RepositoryMarker {

}

a.b.c.entities.Student

//dummy class and dummy query
@Entity
@NamedQueries({
@NamedQuery(name="Student.findByKey", query="select s from Student s where s.fromDate=:fromDate" and s.toDate = :toDate)
})
public class Student implements Serializable {

    private LocalDateTime fromDate;
    private LocalDateTime toDate;

    //getters setters

}

a.b.c.converters

@Converter(autoApply = true)
public class LocalDateTimeConverter implements AttributeConverter<LocalDateTime, Timestamp> {

    @Override
    public Timestamp convertToDatabaseColumn(LocalDateTime dateTime) {

        if (dateTime == null) {
            return null;
        }
        return Timestamp.valueOf(dateTime);
    }

    @Override
    public LocalDateTime convertToEntityAttribute(Timestamp timestamp) {

        if (timestamp == null) {
            return null;
        }    
        return timestamp.toLocalDateTime();
    }
}

Check the ES server logs

sudo tail -f /var/log/elasticsearch/elasticsearch.log

I was using an outdated client

Received message from unsupported version: [5.0.0] minimal compatible version is: [6.8.0]

for the new users on Mac os , find out .m2 folder and delete it, its on your /Users/.m2 directory.

you wont get to see .m2 folder in finder(File Explorer), for this user this command to Show Mac hidden files

$ defaults write com.apple.finder AppleShowAllFiles TRUE

after this press alt and click on finder-> relaunch, you can see /Users/.m2

to hide files again, simply use this $ defaults write com.apple.finder AppleShowAllFiles false

I made a annotation library that can do the cast for you. check this out. https://github.com/zeroarst/callbackfragment/

@CallbackFragment
public class MyFragment extends Fragment {

    @Callback
    interface FragmentCallback {
       void onClickButton(MyFragment fragment);
    }    
    private FragmentCallback mCallback;

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.bt1
                mCallback.onClickButton(this);
                break;
            case R.id.bt2
                // Because we give mandatory = false so this might be null if not implemented by the host.
                if (mCallbackNotForce != null)
                mCallbackNotForce.onClickButton(this);
                break;
        }
    }
}

It then generates a subclass of your fragment. And just add it to FragmentManager.

public class MainActivity extends AppCompatActivity implements MyFragment.FragmentCallback {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        getSupportFragmentManager().beginTransaction()
            .add(R.id.lo_fragm_container, MyFragmentCallbackable.create(), "MY_FRAGM")
            .commit();
    }

    Toast mToast;

    @Override
    public void onClickButton(MyFragment fragment) {
        if (mToast != null)
            mToast.cancel();
        mToast = Toast.makeText(this, "Callback from " + fragment.getTag(), Toast.LENGTH_SHORT);
        mToast.show();
    }
}

Change the order of statments. For me, changing the block of code

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/beans/spring-beans.xsd" 

with

xsi:schemaLocation="http://www.springframework.org/schema/beans 
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/context"

is valid.

As of version 2.4 of the Maven Dependency Plugin, you can also define a target destination for the artifact by using the -Ddest flag. It should point to a filename (not a directory) for the destination artifact. See the parameter page for additional parameters that can be used

mvn org.apache.maven.plugins:maven-dependency-plugin:2.4:get \
    -DremoteRepositories=http://download.java.net/maven/2 \
    -Dartifact=robo-guice:robo-guice:0.4-SNAPSHOT \
    -Ddest=c:\temp\robo-guice.jar

Implementation of seconds/minutes/hours, which are rails methods. Note that implicit returns aren't needed, but they look cleaner, so I prefer them. I'm not sure Rails even has .days or if it goes further, but these are the ones I need.

class Integer
   def seconds
      return self
   end
   def minutes
      return self * 60
   end
   def hours
      return self * 3600
   end
   def days
      return self * 86400
   end
end

After this, you can do: sleep 5.seconds to sleep for 5 seconds. You can do sleep 5.minutes to sleep for 5 min. You can do sleep 5.hours to sleep for 5 hours. And finally, you can do sleep 5.days to sleep for 5 days... You can add any method that return the value of self * (amount of seconds in that timeframe). As an exercise, try implementing it for months!

Having a script or even a subsystem of an application for a network protocol debugging, it's desired to see what request-response pairs are exactly, including effective URLs, headers, payloads and the status. And it's typically impractical to instrument individual requests all over the place. At the same time there are performance considerations that suggest using single (or few specialised) requests.Session, so the following assumes that the suggestion is followed.

requests supports so called event hooks (as of 2.23 there's actually only response hook). It's basically an event listener, and the event is emitted before returning control from requests.request. At this moment both request and response are fully defined, hence can be logged.

import logging

import requests


logger = logging.getLogger('httplogger')

def logRoundtrip(response, *args, **kwargs):
    extra = {'req': response.request, 'res': response}
    logger.debug('HTTP roundtrip', extra=extra)

session = requests.Session()
session.hooks['response'].append(logRoundtrip)

That's basically how to log all HTTP round-trips of a session.

Formatting HTTP round-trip log records

For the logging above to be useful there can be specialised logging formatter that understands req and res extras on logging records. It can look like this:

import textwrap

class HttpFormatter(logging.Formatter):   

    def _formatHeaders(self, d):
        return '\n'.join(f'{k}: {v}' for k, v in d.items())

    def formatMessage(self, record):
        result = super().formatMessage(record)
        if record.name == 'httplogger':
            result += textwrap.dedent('''
                ---------------- request ----------------
                {req.method} {req.url}
                {reqhdrs}

                {req.body}
                ---------------- response ----------------
                {res.status_code} {res.reason} {res.url}
                {reshdrs}

                {res.text}
            ''').format(
                req=record.req,
                res=record.res,
                reqhdrs=self._formatHeaders(record.req.headers),
                reshdrs=self._formatHeaders(record.res.headers),
            )

        return result

formatter = HttpFormatter('{asctime} {levelname} {name} {message}', style='{')
handler = logging.StreamHandler()
handler.setFormatter(formatter)
logging.basicConfig(level=logging.DEBUG, handlers=[handler])

Now if you do some requests using the session, like:

session.get('https://httpbin.org/user-agent')
session.get('https://httpbin.org/status/200')

The output to stderr will look as follows.

2020-05-14 22:10:13,224 DEBUG urllib3.connectionpool Starting new HTTPS connection (1): httpbin.org:443

A GUI way

When you have a lot of queries, having a simple UI and a way to filter records comes at handy. I'll show to use Chronologer for that (which I'm the author of).

First, the hook has be rewritten to produce records that logging can serialise when sending over the wire. It can look like this:

def logRoundtrip(response, *args, **kwargs): 
    extra = {
        'req': {
            'method': response.request.method,
            'url': response.request.url,
            'headers': response.request.headers,
            'body': response.request.body,
        }, 
        'res': {
            'code': response.status_code,
            'reason': response.reason,
            'url': response.url,
            'headers': response.headers,
            'body': response.text
        },
    }
    logger.debug('HTTP roundtrip', extra=extra)

session = requests.Session()
session.hooks['response'].append(logRoundtrip)

Second, logging configuration has to be adapted to use logging.handlers.HTTPHandler (which Chronologer understands).

import logging.handlers

chrono = logging.handlers.HTTPHandler(
  'localhost:8080', '/api/v1/record', 'POST', credentials=('logger', ''))
handlers = [logging.StreamHandler(), chrono]
logging.basicConfig(level=logging.DEBUG, handlers=handlers)

Finally, run Chronologer instance. e.g. using Docker:

docker run --rm -it -p 8080:8080 -v /tmp/db \
    -e CHRONOLOGER_STORAGE_DSN=sqlite:////tmp/db/chrono.sqlite \
    -e CHRONOLOGER_SECRET=example \
    -e CHRONOLOGER_ROLES="basic-reader query-reader writer" \
    saaj/chronologer \
    python -m chronologer -e production serve -u www-data -g www-data -m

And run the requests again:

session.get('https://httpbin.org/user-agent')
session.get('https://httpbin.org/status/200')

The stream handler will produce:

DEBUG:urllib3.connectionpool:Starting new HTTPS connection (1): httpbin.org:443
DEBUG:urllib3.connectionpool:https://httpbin.org:443 "GET /user-agent HTTP/1.1" 200 45
DEBUG:httplogger:HTTP roundtrip
DEBUG:urllib3.connectionpool:https://httpbin.org:443 "GET /status/200 HTTP/1.1" 200 0
DEBUG:httplogger:HTTP roundtrip

Now if you open http://localhost:8080/ (use "logger" for username and empty password for the basic auth popup) and click "Open" button, you should see something like:

As quick n dirty fix, this worked for me: Adding this 2 lines before the problematic import:

import sys
sys.path.append('C:\\Python27\\Lib\site-packages')

In addition to the solutions posted above, having gone through the exact same problem, make sure you check your HTML. More specifically whether you've properly labelled your elements, as well as class and id selectors. You can do this either manually or through a validator (https://validator.w3.org/).

For me, I missed the equal sign next to the class (<div class someDiv> vs <div class = "someDiv">, hence why no CSS property was applied.

You do not need to do it. In C (not C++) you were required to use enum Enumname to refer to a data element of the enumerated type. To simplify it you were allowed to typedef it to a single name data type.

typedef enum MyEnum { 
  //...
} MyEnum;

allowed functions taking a parameter of the enum to be defined as

void f( MyEnum x )

instead of the longer

void f( enum MyEnum x )

Note that the name of the typename does not need to be equal to the name of the enum. The same happens with structs.

In C++, on the other hand, it is not required, as enums, classes and structs can be accessed directly as types by their names.

// C++
enum MyEnum {
   // ...
};
void f( MyEnum x ); // Correct C++, Error in C

<content>(?:[^\n]*(\n+))+</content>

I also think it is important to note that Python dict object type is a hash table (more on this here), and thus is not capable of being sorted without converting its keys/values to lists. What this allows is dict item retrieval in constant time O(1), no matter the size/number of elements in a dictionary.

Having said that, once you sort its keys - sorted(data.keys()), or values - sorted(data.values()), you can then use that list to access keys/values in design patterns such as these:

for sortedKey in sorted(dictionary):
    print dictionary[sortedKeY] # gives the values sorted by key

for sortedValue in sorted(dictionary.values()):
    print sortedValue # gives the values sorted by value

Hope this helps.

I pass around a simple Hashtable object with a single result member to avoid the return craziness as I also want to output to the console. It acts through pass by reference.

function sample-loop($returnObj) {
  for($i = 0; $i -lt 10; $i++) {
    Write-Host "loop counter: $i"
    $returnObj.result++
  }
}

function main-sample() {
  $countObj = @{ result = 0 }
  sample-loop -returnObj $countObj
  Write-Host "_____________"
  Write-Host "Total = " ($countObj.result)
}

main-sample

See the first answer to Accessing a matrix element in the "Mat" object (not the CvMat object) in OpenCV C++
Then just loop over all the elements in cout << M.at<double>(0,0); rather than just 0,0

Or better still with the C++ interface:

cv::Mat M;
cout << "M = " << endl << " "  << M << endl << endl;

OFFICE 2013 INSTRUCTIONS:

(For Windows 7 (x64) | MS Office 32-Bit)

Option 1 | Check if ability already exists | 2 minutes

1. Open VB Editor
2. Tools -> Additional Controls
3. Select "Microsoft Monthview Control 6.0 (SP6)" (if applicable)
4. Use 'DatePicker' control for VBA Userform

Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes

1. Close Excel
2. Download MSCOMCT2.cab (it's a cabinet file which extracts into two useful files)
3. Extract Both Files | the .inf file and the .ocx file
4. Install | right-click the .inf file | hit "Install"
5. Move .ocx file | Move from "C:\Windows\system32" to "C:\Windows\sysWOW64"
6. Run CMD | Start Menu -> Search -> "CMD.exe" | right-click the icon | Select "Run as administrator"
7. Register Active-X File | Type "regsvr32 c:\windows\sysWOW64\MSCOMCT2.ocx"
8. Open Excel | Open VB Editor
9. Activate Control | Tools->References | Select "Microsoft Windows Common Controls 2-6.0 (SP6)"
10. Userform Controls | Select any userform in VB project | Tools->Additional Controls
11. Select "Microsoft Monthview Control 6.0 (SP6)"
12. Use 'DatePicker' control for VBA UserForm

Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.

The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

There is a much easier way to set the color programmatically by setting ColorStateList.

 Checkbox.setButtonTintList(ColorStateList.valueOf(getContext().getColor(R.color.yourcolor)))

The count function is meant to be used on

1. Arrays
2. Objects that are derived from classes that implement the countable interface

A stdClass is neither of these. The easier/quickest way to accomplish what you're after is

$count = count(get_object_vars($some_std_class_object));

This uses PHP's get_object_vars function, which will return the properties of an object as an array. You can then use this array with PHP's count function.

something like

String source = "password"; 
byte[] byteArray;
try {
    byteArray = source.getBytes("UTF-16");
    System.out.println(new String(Base64.decode(Base64.encode(byteArray,
           Base64.DEFAULT), Base64.DEFAULT)));
} catch (UnsupportedEncodingException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Make the the table-cell position relative, then make the inner div position absolute, with top/right/bottom/left all set to 0px.

.table-cell {
  display: table-cell;
  position: relative;
}

.inner-div {
  position: absolute;
  top: 0px;
  right: 0px;
  bottom: 0px;
  left: 0px;
}

I realize this question is asking about how to encode an associative array to a pretty-formatted JSON string, so this doesn't directly answer the question, but if you have a string that is already in JSON format, you can make it pretty simply by decoding and re-encoding it (requires PHP >= 5.4):

$json = json_encode(json_decode($json), JSON_PRETTY_PRINT);

Example:

header('Content-Type: application/json');
$json_ugly = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
$json_pretty = json_encode(json_decode($json_ugly), JSON_PRETTY_PRINT);
echo $json_pretty;

This outputs:

{
    "a": 1,
    "b": 2,
    "c": 3,
    "d": 4,
    "e": 5
}

Choose "iPhone developer" then select the provisional profile you created.

You can use the change event to monitor what the user selects and notify them at that point that the file is not acceptable. It does not limit the actual list of files displayed, but it is the closest you can do client-side, besides the poorly supported accept attribute.

var file = document.getElementById('someId');_x000D_
_x000D_
file.onchange = function(e) {_x000D_
  var ext = this.value.match(/\.([^\.]+)$/)[1];_x000D_
  switch (ext) {_x000D_
    case 'jpg':_x000D_
    case 'bmp':_x000D_
    case 'png':_x000D_
    case 'tif':_x000D_
      alert('Allowed');_x000D_
      break;_x000D_
    default:_x000D_
      alert('Not allowed');_x000D_
      this.value = '';_x000D_
  }_x000D_
};

<input type="file" id="someId" />

I had the same problem and I found this is working:

if ($("#deliveryNext").attr('disabled')) {
  // do sth if disabled
} else {
  // do sth if enabled 
}

If this gives you undefined then you can use if condition also.

When you evaluate undefined it will return false.

truncate tableName

That is what you are looking for.

Truncate will delete all records in the table, emptying it.

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

<...JPEG content in base64...>
--HereGoes--

Most form inputs are always set, even if not filled up, so you must check for the emptiness too.

Since !empty() is already checks for both, you can use this:

if (!empty($_POST["mail"])) {
    echo "Yes, mail is set";    
} else {  
    echo "No, mail is not set";
}

This line did solve the issue in my case,

sudo apt clean

I tried this code below and it's working fine

SELECT        TimeTrackEmployee.StaffID
FROM            dbo.tblGBSTimeCard AS GBSTimeCard INNER JOIN
                         TimeTrak.dbo.tblEmployee AS TimeTrackEmployee ON GBSTimeCard.[Employee Number] = TimeTrackEmployee.GBSStaffID

I guess this has been solved by now but still the best thing to do here is to send the token with your form

{!! csrf_field() !!}

and then in your ajax

$("#try").click(function(){
var url = $(this).attr("data-link");
$.ajax({
    url: "test",
    type:"POST",
    data: { '_token': token, 'someOtherData': someOtherData },
    success:function(data){
        alert(data);
    },error:function(){ 
        alert("error!!!!");
    }
}); //end of ajax
});

I tried to update my project to use the sass using this command

ng set defaults.styleExt scss

but got this

get/set have been deprecated in favor of the config command.

• Angular CLI: 6.0.7
• Node: 8.9.0
• OS: linux x64
• Angular: 6.0.3

So I deleted my project (as I was just getting started and had no code in my project) and created a new one with sass initially set

ng new my-sassy-app --style=scss

But I would appreciate if someone can share a way to update the existing project as that would be nice.

Requires jquery and animates to anchor tag with the specified name instead of id, while adding the hash to browser url. Also fixes an error in most answers with jquery where the # sign is not prefixed with an escaping backslash. The back button, unfortunately, does not navigate back properly to previous hash links...

$('a[href*=\\#]').click(function (event)
{
    let hashValue = $(this).attr('href');
    let name = hashValue.substring(1);
    let target = $('[name="' + name + '"]');
    $('html, body').animate({ scrollTop: target.offset().top }, 500);
    event.preventDefault();
    history.pushState(null, null, hashValue);
});

The following code worked for me

let link = document.createElement('a');
link.href = data.fileurl; //data is object received as response
link.download = data.fileurl.substr(data.fileurl.lastIndexOf('/') + 1);
link.click();

On Version 1.9.6.1. For UnPushed commit.

1. Click on previously committed description
2. Click Commit icon
3. Enter new commit message, and choose "Ammend latest commit" from the Commit options dropdown.
4. Commit your message.

Add the css

  <style type="text/css">
    textarea
    {

        border:1px solid #999999
        width:99%;
        margin:5px 0;
        padding:1%;
    }
</style>

Using JavaScript

 public ActionResult Index()
 {
    return Content("<script>window.location = 'http://www.example.com';</script>");
 }

Note: As @Jeremy Ray Brown said , This is not the best option but you might find useful in some situations.

Hope this helps.

Try this:

var itemsInCart = from o in db.OrderLineItems
                  where o.OrderId == currentOrder.OrderId
                  select o.WishListItem.Price;

return Convert.ToDecimal(itemsInCart.Sum());

I think it's more simple!

You can call it like that:

<!DOCTYPE html>
<html lang="en">
    <head>
        <script type="text/javascript">
            var person = { name: 'Joe Blow' };
            function myfunction() {
               document.write(person.name);
            }
        </script>
    </head>
    <body>
        <script type="text/javascript">
            myfunction();
        </script>
    </body>
</html>

The result should be page with the only content: Joe Blow

Add colspan="2" to the 3rd <th> and then have 4 <td>'s in your second row.

    <th scope="col">Header</th>
    <th scope="col">Header</th>
    <th scope="col" colspan="2">Header</th>
  </tr>

    <th scope="row">&nbsp;</th>
    <td>&nbsp;</td>
    <!-- The following two cells will appear under the same header -->
    <td>Col 1</td>
    <td>Col 2</td>
  </tr>

Use this:

 android:layout_height="wrap_content"
 android:background="@null"
 android:padding="10dp"

var x = $('#h_v').val();
alert(x);

You can also enter msinfo32 into the command line.

It will bring up all your system information. Then, in the find box, just enter processor and it will show you your cores and logical processors for each CPU. I found this way to be easiest.

These solutions work, but they work for your code ONLY on your machine. I would add a couple of lines to your code that look like this:

import sys
if "C:\\My_Python_Lib" not in sys.path:
    sys.path.append("C:\\My_Python_Lib")

That should take care of your problems

        var elementViewInBottom = objectPosTop - winHeight;
    $(window).on('scroll', function() {
        var currentPosition = $(document).scrollTop();
        //when element position starting in viewport
      if (currentPosition > elementViewInBottom && firEvent === false) {
        firEvent = true;
        animationCounter();
      }   
    });
}

//counter function will animate by using external js also add seprator "."

Take a look at UrlRewriteFilter which is essentially a java-based implementation of Apache's mod_rewrite.

You'll need to extract it into ROOT folder under your Tomcat's webapps folder; you can then configure redirects to any other context within its WEB-INF/urlrewrite.xml configuration file.

There are several answers that cover how to solve this if you have a UNIQUE index that you can check against with ON DUPLICATE KEY or INSERT IGNORE. That is not always the case, and as UNIQUE has a length constraint (1000 bytes) you might not be able to change that. For example, I had to work with metadata in WordPress (wp_postmeta).

I finally solved it with two queries:

UPDATE wp_postmeta SET meta_value = ? WHERE meta_key = ? AND post_id = ?;
INSERT INTO wp_postmeta (post_id, meta_key, meta_value) SELECT DISTINCT ?, ?, ? FROM wp_postmeta WHERE NOT EXISTS(SELECT * FROM wp_postmeta WHERE meta_key = ? AND post_id = ?);

Query 1 is a regular UPDATE query with no effect when the dataset in question is not there. Query 2 is an INSERT which depends on a NOT EXISTS, i.e. the INSERT is only executed when the dataset doesn't exist.

Assumed you have data frame as below

df1
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

When you would like create another df2 which is identical to df1, without copy

df2=df1
df2
     A    B    C    D
4 -1.0 -1.0 -1.0 -1.0
5 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0
6 -1.0 -1.0 -1.0 -1.0

And would like modify the df2 value only as below

df2.iloc[0,0]='changed'

df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

At the same time the df1 is changed as well

df1
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Since two df as same object, we can check it by using the id

id(df1)
140367679979600
id(df2)
140367679979600

So they as same object and one change another one will pass the same value as well.

If we add the copy, and now df1 and df2 are considered as different object, if we do the same change to one of them the other will not change.

df2=df1.copy()
id(df1)
140367679979600
id(df2)
140367674641232

df1.iloc[0,0]='changedback'
df2
         A    B    C    D
4  changed -1.0 -1.0 -1.0
5       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0
6       -1 -1.0 -1.0 -1.0

Good to mention, when you subset the original dataframe, it is safe to add the copy as well in order to avoid the SettingWithCopyWarning

Now that Javascript has lookbehind (as of ES2018), on newer environments, you can avoid groups entirely in situations like these. Rather, lookbehind for what comes before the group you were capturing, and lookahead for what comes after, and replace with just !NEW_ID!:

const str = 'name="some_text_0_some_text"';
console.log(
  str.replace(/(?<=name="\w+)\d+(?=\w+")/, '!NEW_ID!')
);

With this method, the full match is only the part that needs to be replaced.

• (?<=name="\w+) - Lookbehind for name=", followed by word characters (luckily, lookbehinds do not have to be fixed width in Javascript!)
• \d+ - Match one or more digits - the only part of the pattern not in a lookaround, the only part of the string that will be in the resulting match
• (?=\w+") - Lookahead for word characters followed by " `

Keep in mind that lookbehind is pretty new. It works in modern versions of V8 (including Chrome, Opera, and Node), but not in most other environments, at least not yet. So while you can reliably use lookbehind in Node and in your own browser (if it runs on a modern version of V8), it's not yet sufficiently supported by random clients (like on a public website).

In your example, the TMP variable is set (and the temporary directory created) whenever the rules for out.tar are evaluated. In order to create the directory only when out.tar is actually fired, you need to move the directory creation down into the steps:

out.tar : 
    $(eval TMP := $(shell mktemp -d))
    @echo hi $(TMP)/hi.txt
    tar -C $(TMP) cf $@ .
    rm -rf $(TMP)

The eval function evaluates a string as if it had been typed into the makefile manually. In this case, it sets the TMP variable to the result of the shell function call.

edit (in response to comments):

To create a unique variable, you could do the following:

out.tar : 
    $(eval $@_TMP := $(shell mktemp -d))
    @echo hi $($@_TMP)/hi.txt
    tar -C $($@_TMP) cf $@ .
    rm -rf $($@_TMP)

This would prepend the name of the target (out.tar, in this case) to the variable, producing a variable with the name out.tar_TMP. Hopefully, that is enough to prevent conflicts.

This link (How to get line count cheaply in Python?) has lots of potential solutions, but they all ignore one way to make this run considerably faster, namely by using the unbuffered (raw) interface, using bytearrays, and doing your own buffering.

Using a modified version of the timing tool, I believe the following code is faster (and marginally more pythonic) than any of the solutions offered:

def _make_gen(reader):
    b = reader(1024 * 1024)
    while b:
        yield b
        b = reader(1024*1024)

def rawpycount(filename):
    f = open(filename, 'rb')
    f_gen = _make_gen(f.raw.read)
    return sum( buf.count(b'\n') for buf in f_gen )

Here are my timings:

rawpycount        0.0048  0.0046   1.00
bufcount          0.0074  0.0066   1.43
wccount             0.01    0.01   2.17
itercount          0.014   0.014   3.04
opcount            0.021    0.02   4.43
kylecount          0.023   0.021   4.58
simplecount        0.022   0.022   4.81
mapcount           0.038   0.032   6.82

I would post it there, but I'm a relatively new user to stack exchange and don't have the requisite manna.

EDIT:

This can be done completely with generators expressions in-line using itertools, but it gets pretty weird looking:

from itertools import (takewhile,repeat)

def rawbigcount(filename):
    f = open(filename, 'rb')
    bufgen = takewhile(lambda x: x, (f.raw.read(1024*1024) for _ in repeat(None)))
    return sum( buf.count(b'\n') for buf in bufgen if buf )

this one is out of left field but its a nice little map for resizing your current split to 80 characters if you've got the line numbers on:

" make window 80 + some for numbers wide  
noremap <Leader>w :let @w=float2nr(log10(line("$")))+82\|:vertical resize <c-r>w<cr> 

You must use %ld to print a long int, and %lld to print a long long int.

Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you're using).

You will also need to ensure that you use your compiler in a C99-compatible mode (for example, using the -std=gnu99 option to gcc). This is because the long long int type was not introduced until C99; and although many compilers implement long long int in C90 mode as an extension, the constant 2147483648 may have a type of unsigned int or unsigned long in C90. If this is the case in your implementation, then the value of -2147483648 will also have unsigned type and will therefore be positive, and the overall result will be not what you expect.

    std::cout << std::endl;
}

if you want to encode or decode an array from or to JSON you can use these functions

$myJSONString = json_encode($myArray);
$myArray = json_decode($myString);

json_encode will result in a JSON string, built from an (multi-dimensional) array. json_decode will result in an Array, built from a well formed JSON string

with json_decode you can take the results from the API and only output what you want, for example:

echo $myArray['payload']['ign'];

iOS 4.3.2's User Agent, which came out this week, is:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 4_3_2 like Mac OS X; en-us) AppleWebKit/533.17.9 (KHTML, like Gecko) Version/5.0.2 Mobile/8H7 Safari/6533.18.5

I had a similar problem in VS 2017 15.45 - I found when I checked that even though the project compiled and ran it came up with a system.IO.FileNotFoundException with regard to System.Runtime when I tried to access TPL Dataflow objects.

When I checked the projects in the solution, one of them (the top one) was missing the System.Runtime package used by the underlying projects. Once I installed it from Nuget it all worked correctly.

I think the best way is Convert.ToInt32.

Substring. This method extracts strings. It requires the location of the substring (a start index, a length). It then returns a new string with the characters in that range.

See a small example :

string input = "OneTwoThree";
// Get first three characters.
string sub = input.Substring(0, 3);
Console.WriteLine("Substring: {0}", sub);

Output : Substring: One

Using restart: unless-stopped or restart: always may solve this problem.

If worker container stops when rabbitMQ is not ready, it will be restarted until it is.

For MySql WorkBench, Please use below :

update emp as a
inner join department b on a.department_id=b.id
set a.department_name=b.name
where a.emp_id in (10,11,12); 

The shortest code would be:

Select CAST((@EndDateTime-@StartDateTime) as time(0)) '[hh:mm:ss]'

You can do:

git diff master~20:pom.xml pom.xml

... to compare your current pom.xml to the one from master 20 revisions ago through the first parent. You can replace master~20, of course, with the object name (SHA1sum) of a commit or any of the many other ways of specifying a revision.

Note that this is actually comparing the old pom.xml to the version in your working tree, not the version committed in master. If you want that, then you can do the following instead:

git diff master~20:pom.xml master:pom.xml

Here's the correct answer, extracted from comments by Daniel Rikowski and pseidemann. I'm tired of having to weed through comments to find the right answer...

If you use Rails (ActiveSupport):

result.class.name.demodulize

If you use POR (plain-ol-Ruby):

result.class.name.split('::').last

Similar to @Smar but uses file system paths, set in PRIMARY and SECONDARY:

PRIMARY=~/Code/project1
SECONDARY=~/Code/project2
cd $PRIMARY
git remote add test $SECONDARY && git fetch test
git merge test/master

Then you manually merge.

clear:both makes the element drop below any floated elements that precede it in the document.

You can also use clear:left or clear:right to make it drop below only those elements that have been floated left or right.

Another way to check on connection attempts is to look at the server's event log. On my Windows 2008 R2 Enterprise machine I opened the server manager (right-click on Computer and select Manage. Then choose Diagnostics -> Event Viewer -> Windows Logs -> Applcation. You can filter the log to isolate the MSSQLSERVER events. I found a number that looked like this

Login failed for user 'bogus'. The user is not associated with a trusted SQL Server connection. [CLIENT: 10.12.3.126]

Maybe remove the semi-colon after set because now the where statement doesn't belong to the update statement. Also the idRequest could be a problem, better write BookingRequest.idRequest

Or u can do it this way. The function u put the below 6 lines will throw an IOException. And will take your JLabel as a parameter.

BufferedImage bi=new BufferedImage(label.width(),label.height(),BufferedImage.TYPE_INT_RGB);

Graphics2D g=bi.createGraphics();

Image img=ImageIO.read(new File("path of your image"));

g.drawImage(img, 0, 0, label.width(), label.height(), null);

g.dispose();

return bi;

for those stumbling upon this question: the python jsonlines library (much younger than this question) elegantly handles files with one json document per line. see https://jsonlines.readthedocs.io/

Portability between Linux and Windows is a big headache, since Linux is a POSIX-conformant system with - generally - a proper, high quality toolchain for C, whereas Windows doesn't even provide a lot of functions in the C standard library.

However, if you want to stick to the standard, you can write something like this:

#include <stdio.h>
#include <stdlib.h>

FILE *f = fopen("textfile.txt", "rb");
fseek(f, 0, SEEK_END);
long fsize = ftell(f);
fseek(f, 0, SEEK_SET);  /* same as rewind(f); */

char *string = malloc(fsize + 1);
fread(string, 1, fsize, f);
fclose(f);

string[fsize] = 0;

Here string will contain the contents of the text file as a properly 0-terminated C string. This code is just standard C, it's not POSIX-specific (although that it doesn't guarantee it will work/compile on Windows...)

From OP's example:

 public static int Method1(string mystring)
 {
      return 1;
 }

 public static int Method2(string mystring)
 {
     return 2;
 }

You can try Action Delegate! And then call your method using

 public bool RunTheMethod(Action myMethodName)
 {
      myMethodName();   // note: the return value got discarded
      return true;
 }

RunTheMethod(() => Method1("MyString1"));

Or

public static object InvokeMethod(Delegate method, params object[] args)
{
     return method.DynamicInvoke(args);
}

Then simply call method

Console.WriteLine(InvokeMethod(new Func<string,int>(Method1), "MyString1"));

Console.WriteLine(InvokeMethod(new Func<string, int>(Method2), "MyString2"));

  import ReactDOM from 'react-dom';
  //...
  componentDidMount() {
    var n = ReactDOM.findDOMNode(this);
    console.log(n.offsetTop);
  }

You can just grab the offsetTop from the Node.

Since you are new to Android development you may not know about Content Providers, which are database abstractions. They may not be the right thing for your project, but you should check them out: http://developer.android.com/guide/topics/providers/content-providers.html

If you're looking for efficiency, use this:

string.Equals(val, "astringvalue", StringComparison.OrdinalIgnoreCase)

Ordinal comparisons can be significantly faster than culture-aware comparisons.

ToLowerCase can be the better option if you're doing a lot of comparisons against the same string, however.

As with any performance optimization: measure it, then decide!

Updated answer @Arsonik answer to Swift 2.2, using less verbose code than other offered solutions:

extension String {
    func isValidEmail() -> Bool {
        let regex = try? NSRegularExpression(pattern: "^[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(?:\\.[a-zA-Z0-9](?:[a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?)*$", options: .CaseInsensitive)
        return regex?.firstMatchInString(self, options: [], range: NSMakeRange(0, self.characters.count)) != nil
    }
}

My solution is to add hover-active css class to the HTML tag, and use it on the beginning of all the CSS selectors with :hover and remove that class on the first touchstart event.

http://codepen.io/Bnaya/pen/EoJlb

JS:

(function () {
    'use strict';

    if (!('addEventListener' in window)) {
        return;
    }

    var htmlElement = document.querySelector('html');

    function touchStart () {
        document.querySelector('html').classList.remove('hover-active');

        htmlElement.removeEventListener('touchstart', touchStart);
    }

    htmlElement.addEventListener('touchstart', touchStart);
}());

HTML:

<html class="hover-active">

CSS:

.hover-active .mybutton:hover {
    box-shadow: 1px 1px 1px #000;
}

I use this one to validate emails often and it works like a charm. This validates that the email must have atleast one character before the @, and at least one character before the "."

public static bool ValidateEmail(string value, bool required, int minLength, int maxLength)
        {
           value = value.Trim();
           if (required == false && value == "") return true;
           if (required && value == "") return false;
           if (value.Length < minLength || value.Length > maxLength) return false;

           //Email must have at least one character before an @, and at least one character before the .
           int index = value.IndexOf('@');
           if (index < 1 || value.LastIndexOf('.') < index + 2) return false;
           return true;
        }

<Text>
    <Text style={{fontWeight: "bold"}}>bold</Text>
    normal text
    <Text style={{fontStyle: "italic"}}> italic</Text>
</Text>

extension UILabel{

    func setSubTextColor(pSubString : String, pColor : UIColor){


        let attributedString: NSMutableAttributedString = self.attributedText != nil ? NSMutableAttributedString(attributedString: self.attributedText!) : NSMutableAttributedString(string: self.text!);


        let range = attributedString.mutableString.range(of: pSubString, options:NSString.CompareOptions.caseInsensitive)
        if range.location != NSNotFound {
            attributedString.addAttribute(NSForegroundColorAttributeName, value: pColor, range: range);
        }
        self.attributedText = attributedString

    }
}

Let us assume that the class is Data with two objects name and dob which are both strings.

Initially, check if the list is empty. Then, add the objects from the list to a JSONArray

JSONArray allDataArray = new JSONArray();
List<Data> sList = new ArrayList<String>();

    //if List not empty
    if (!(sList.size() ==0)) {

        //Loop index size()
        for(int index = 0; index < sList.size(); index++) {
            JSONObject eachData = new JSONObject();
            try {
                eachData.put("name", sList.get(index).getName());
                eachData.put("dob", sList.get(index).getDob());
            } catch (JSONException e) {
                e.printStackTrace();
            }
            allDataArray.put(eachData);
        }
    } else {
        //Do something when sList is empty
    }

Finally, add the JSONArray to a JSONObject.

JSONObject root = new JSONObject();
    try {
        root.put("data", allDataArray);
    } catch (JSONException e) {
        e.printStackTrace();
    }

You can further get this data as a String too.

String jsonString = root.toString();

I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)

The screen you show is DateTimeSettings. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time"; and also to Settings.System.AUTO_TIME

This settings is observed by an observed called mAutoTimeObserver in the 2 network ServiceStateTrackers: GsmServiceStateTracker and CdmaServiceStateTracker.

Both implementations call a method called revertToNitz() when the settings becomes true. Apparently NITZ is the equivalent of NTP in the carrier world.

Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz(). Unfortunately, I haven't found a mechanism to get the network time. If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTrackers implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime.

You can change default options by using Chart.defaults.global in your javascript file. So you want to change legend and tooltip options.

Remove legend

Chart.defaults.global.legend.display = false;

Remove Tooltip

Chart.defaults.global.tooltips.enabled = false;

Here is a working fiddler.

Try redirecting the output to Out-Null. Like so,

$key = & 'gpg' --decrypt "secret.gpg" --quiet --no-verbose | out-null

Yes, you can do that which returns boolean. The following java code in WebDriver with TestNG or JUnit can do:

protected boolean isTextPresent(String text){
    try{
        boolean b = driver.getPageSource().contains(text);
        return b;
    }
    catch(Exception e){
        return false;
    }
  }

Now call the above method as below:

assertTrue(isTextPresent("Your text"));

Or, there is another way. I think, this is the better way:

private StringBuffer verificationErrors = new StringBuffer();
try {
                  assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*    Your text here\r\n\r\n[\\s\\S]*$"));
  } catch (Error e) {
     verificationErrors.append(e.toString());
   }

you need to have mysql connector jar in your classpath.

in Java JDBC API makes everything with databases. using JDBC we can write Java applications to
1. Send queries or update SQL to DB(any relational Database) 2. Retrieve and process the results from DB

with below three steps we can able to retrieve data from any Database

Connection con = DriverManager.getConnection(
                     "jdbc:myDriver:DatabaseName",
                     dBuserName,
                     dBuserPassword);

Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT a, b, c FROM Table");

while (rs.next()) {
    int x = rs.getInt("a");
    String s = rs.getString("b");
    float f = rs.getFloat("c");
}

All code below was tested with Python 3.8.3

Simplest -- just use triple quotes.
Either single:

long_string = '''some
very 
long
string
............'''

or double:

long_string = """some
very 
long
string
............"""

Note: triple quoted strings retain indentation, it means that

long_string = """some
    very 
    long
string
............"""

and

long_string = """some
    very 
long
string
............"""

or even just

long_string = """
some
very 
long
string
............"""

are not the same.
There is a textwrap.dedent function in standard library to deal with this, though working with it is out of question's scope.

You can, as well, use \n inside a string, residing on single line:

long_string = "some \nvery \nlong \nstring \n............"

Also, if you don't need any linefeeds (i.e. newlines) in your string, you can use \ inside regular string:

long_string = "some \
very \
long \
string \
............"

Following answer may help you

perform your date ordering by your date identifier but use to_char() function in select clause and use some other identifier in select clause for date

e.g.

SELECT TO_CHAR(DISPDATE1,'DD/MM/YYYY') AS DISPDATE,
SUM(APPLCOUNT) AS APPLIED,
SUM(CONFCOUNT) AS CONFIRMED
FROM
    (
        SELECT COUNT(ID) AS APPLCOUNT,
                   0 AS CONFCOUNT,
                   STUDENT.APPLIED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.APPLIED_ON
        UNION
            SELECT 0 AS APPLCOUNT,
                   COUNT(ID) AS CONFCOUNT,
                   STUDENT.CONFIRMED_ON AS DISPDATE1
            FROM STUDENT
            WHERE STUDENT.ID = P_ID
            GROUP BY STUDENT.CONFIRMED_ON
    )
GROUP BY DISPDATE1
ORDER BY DISPDATE1;

The two previous answers demonstrate how to use Canvas and ImageData. I would like to propose an answer with runnable example and using an image processing framework, so you don't need to handle the pixel data manually.

MarvinJ provides the method image.getAlphaComponent(x,y) which simply returns the transparency value for the pixel in x,y coordinate. If this value is 0, pixel is totally transparent, values between 1 and 254 are transparency levels, finally 255 is opaque.

For demonstrating I've used the image below (300x300) with transparent background and two pixels at coordinates (0,0) and (150,150).

Console output:

(0,0): TRANSPARENT
(150,150): NOT_TRANSPARENT

image = new MarvinImage();_x000D_
image.load("https://i.imgur.com/eLZVbQG.png", imageLoaded);_x000D_
_x000D_
function imageLoaded(){_x000D_
  console.log("(0,0): "+(image.getAlphaComponent(0,0) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
  console.log("(150,150): "+(image.getAlphaComponent(150,150) > 0 ? "NOT_TRANSPARENT" : "TRANSPARENT"));_x000D_
}

Yes, but you can select only one column in your subselect

SELECT (SELECT id FROM bla) AS my_select FROM bla2

You can convert char to int and viceversa easily because for the machine an int and a char are the same, 8 bits, the only difference comes when they have to be shown in screen, if the number is 65 and is saved as a char, then it will show 'A', if it's saved as a int it will show 65.

With other types things change, because they are stored differently in memory. There's standard function in C that allows you to convert from string to double easily, it's atof. (You need to include stdlib.h)

#include <stdlib.h>

int main()
{
    string word;  
    openfile >> word;
    double lol = atof(word.c_str()); /*c_str is needed to convert string to const char*
                                     previously (the function requires it)*/
    return 0;
}

This works for me (just an extract from my whole script)

choice /C 1234567H /M "Select an option or ctrl+C to cancel"
set _dpi=%ERRORLEVEL%

if "%_dpi%" == "8" call :helpme && goto menu 

for /F "tokens=%_dpi%,*" %%1 in ("032 060 064 096 0C8 0FA 12C") do set _dpi=%%1
echo _dpi:%_dpi%:

Convert your array y to list l and then do l.count(1) and l.count(0)

>>> y = numpy.array([0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1])
>>> l = list(y)
>>> l.count(1)
4
>>> l.count(0)
8 

Try adding the following line in settings.py:

USE_THOUSAND_SEPARATOR = True

This should work.

Refer to documentation.

update at 2018-04-16:

There is also a python way to do this thing:

>>> '{:,}'.format(1000000)
'1,000,000'

I had android sdk and android studio installed separately in my system. Android studio had installed its own sdk. After I deleted the stand-alone android sdk, the issue of "“No system image installed for this Target” was gone.

Try the cex argument:

?par

• cex
  A numerical value giving the amount by which plotting text and symbols should be magnified relative to the default. Note that some graphics functions such as plot.default have an argument of this name which multiplies this graphical parameter, and some functions such as points accept a vector of values which are recycled. Other uses will take just the first value if a vector of length greater than one is supplied.

how come nobody mentioned

$(this).filter('[value=]').addClass('warning');

seems more jquery-like to me

Assuming you were branching from the master, you don't need to enter yourBranch into the reset step all the time:

git checkout yourBranch
git reset --soft HEAD~$(git rev-list --count HEAD ^master)
git add -A
git commit -m "one commit on yourBranch"

Explanation:

• git rev-list --count HEAD ^master counts the commits since you made your feature branch from the master, f.ex. 20.
• git reset --soft HEAD~20 will make a soft reset of the last 20 commits. This leaves your changes in the files, but removes the commits.

Usage:

In my .bash_profile I have added an alias for gisquash to do this with one command:

# squash all commits into one
alias gisquash='git reset --soft HEAD~$(git rev-list --count HEAD ^master)'

After reseting and committing you need to do a git push --force.

Hint:

If you're using Gitlab >= 11.0 you don't need to do this anymore as it has a squashing option when merging branches.

If you just want to check the value is in Range, use this:

   MIN_VALUE = 1;
   MAX_VALUE = 100;
   $customValue = min(MAX_VALUE,max(MIN_VALUE,$customValue)));

Your format specifier is incorrect. From the printf() man page on my machine:

0 A zero '0' character indicating that zero-padding should be used rather than blank-padding. A '-' overrides a '0' if both are used;

Field Width: An optional digit string specifying a field width; if the output string has fewer characters than the field width it will be blank-padded on the left (or right, if the left-adjustment indicator has been given) to make up the field width (note that a leading zero is a flag, but an embedded zero is part of a field width);

Precision: An optional period, '.', followed by an optional digit string giving a precision which specifies the number of digits to appear after the decimal point, for e and f formats, or the maximum number of characters to be printed from a string; if the digit string is missing, the precision is treated as zero;

For your case, your format would be %09.3f:

#include <stdio.h>

int main(int argc, char **argv)
{
  printf("%09.3f\n", 4917.24);
  return 0;
}

Output:

Note that this answer is conditional on your embedded system having a printf() implementation that is standard-compliant for these details - many embedded environments do not have such an implementation.

Using Lambda expressions:

1. If we don't have a specific class to bind the result:

    var stores = context.Stores.Select(x => new { x.id, x.name, x.city }).ToList();
   

2. If we have a specific class then we need to bind the result with it:

   List<SelectListItem> stores = context.Stores.Select(x => new SelectListItem { Id = x.id, Name = x.name, City = x.city }).ToList();
   

Using simple LINQ expressions:

1. If we don't have a specific class to bind the result:

   var stores = (from a in context.Stores select new { x.id, x.name, x.city }).ToList();
   

2. If we have a specific class then we need to bind the result with it:

   List<SelectListItem> stores = (from a in context.Stores select new SelectListItem{ Id = x.id, Name = x.name, City = x.city }).ToList();
   

If any row would do, try:

select max(user)  
from table;

No where clause.

When you scheduled task, just select "Run whether user is logged on or not" under the "General" tab.

Alternate way is to let the task run as another user.

if you are using XDocument.Load(url); to fetch xml from another domain, it's possible that the host will reject the request and return and unexpected (non-xml) result, which results in the above XmlException

See my solution to this eventuality here: XDocument.Load(feedUrl) returns "Data at the root level is invalid. Line 1, position 1."

Just in case you need to exclude sub folders you can use the ** wildcard to exclude any level of sub directory.

I don't know why you think there's no constructor. See the API.

Inspired by the idea from @MarSoft but I changed the lines like the following:

USERNAME='desireduser'
COMMAND=$0
COMMANDARGS="$(printf " %q" "${@}")"
if [ $(whoami) != "$USERNAME" ]; then
  exec sudo -E su $USERNAME -c "/usr/bin/bash -l $COMMAND $COMMANDARGS"
  exit
fi

I have used sudo to allow a password less execution of the script. If you want to enter a password for the user, remove the sudo. If you do not need the environment variables, remove -E from sudo.

The /usr/bin/bash -l ensures, that the profile.d scripts are executed for an initialized environment.

Here's an option if you have multiple records for each Customer and are looking for the latest balance for each (say they are dated records):

SELECT ID, BALANCE FROM (
    SELECT ROW_NUMBER() OVER (PARTITION BY ID ORDER BY DateModified DESC) as RowNum, ID, BALANCE
    FROM CUSTOMERS
) C
WHERE RowNum = 1

I was able to show/hide a menu this way:

MenuView.java (extends FrameLayout)

private final int ANIMATION_DURATION = 500;

public void showMenu()
{
    setVisibility(View.VISIBLE);
    animate()
            .alpha(1f)
            .setDuration(ANIMATION_DURATION)
            .setListener(null);
}

private void hideMenu()
{
    animate()
            .alpha(0f)
            .setDuration(ANIMATION_DURATION)
            .setListener(new AnimatorListenerAdapter() {
                @Override
                public void onAnimationEnd(Animator animation) {
                    setVisibility(View.GONE);
                }
            });
}

I used placeholders so just follow along, as you might want to still keep the inheritance from the original style.

Before

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{originalBaseStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

After:

styles.xml

<style name="{{yourToolbarStyle}}" parent="{{originalBaseStyle}}">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>

    <item name="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>

Therefore

    android:layout_height="?attr/actionBarSize"

If you're using QT Creator 5.6 you can do that like this:

#include <QIntValidator>

ui->myLineEditName->setValidator( new QIntValidator);

I recomend you put that line after ui->setupUi(this);

I hope this helps.

The Python documentation does explain it.

Tuples and lists are compared lexicographically using comparison of corresponding elements. This means that to compare equal, each element must compare equal and the two sequences must be of the same type and have the same length.

You can use this:

SELECT COUNT(*) FROM (SELECT DISTINCT column_name FROM table_name) AS temp;

This is much faster than:

COUNT(DISTINCT column_name)

If you only need lazy loading, then you could just have a class initialisation method.

EXAMPLE_SET = False
class Example(object):
   @classmethod 
   def initclass(cls):
       global EXAMPLE_SET 
       if EXAMPLE_SET: return
       cls.the_I = 'ok'
       EXAMPLE_SET = True

   def __init__( self ):
      Example.initclass()
      self.an_i = 20

try:
    print Example.the_I
except AttributeError:
    print 'ok class not "loaded"'
foo = Example()
print foo.the_I
print Example.the_I

But the metaclass approach seems cleaner, and with more predictable behavior.

Perhaps what you're looking for is the Singleton design pattern. There's a nice SO QA about implementing shared state in Python.

Try this one.. It is working... Here JSBIN

table tbody { height:300px; overflow-y:scroll; display:block; }
table thead { display:block; }

Try looking here: https://docs.python.org/2/library/re.html

I ran into the same problem you had though. I could only build a regex that would match only the empty string and also "\n". Try trimming/replacing the newline characters in the string with another character first.

I was using http://pythex.org/ and trying weird regexes like these:

()

(?:)

^$

^(?:^\n){0}$

and so on.

@Context ServletContext ctx;
@Context private HttpServletResponse response;

@GET
@Produces(MediaType.APPLICATION_OCTET_STREAM)
@Path("/download/{filename}")
public StreamingOutput download(@PathParam("filename") String fileName) throws Exception {
    final File file = new File(ctx.getInitParameter("file_save_directory") + "/", fileName);
    response.setHeader("Content-Length", String.valueOf(file.length()));
    response.setHeader("Content-Disposition", "attachment; filename=\""+ file.getName() + "\"");
    return new StreamingOutput() {
        @Override
        public void write(OutputStream output) throws IOException,
                WebApplicationException {
            Utils.writeBuffer(new BufferedInputStream(new FileInputStream(file)), new BufferedOutputStream(output));
        }
    };
}

The error means that your are trying to look up JNDI name, that is not attached to any EJB component - the component with that name does not exist.

As far as dir structure is concerned: you have to create a JAR file with EJB components. As I understand you want to play with EJB 2.X components (at least the linked example suggests that) so the structure of the JAR file should be:

/com/mypackage/MyEJB.class /com/mypackage/MyEJBInterface.class /com/mypackage/etc... etc... java classes /META-INF/ejb-jar.xml /META-INF/jboss.xml

The JAR file is more or less ZIP file with file extension changed from ZIP to JAR.

BTW. If you use JBoss 5, you can work with EJB 3.0, which are much more easier to configure. The simplest component is

@Stateless(mappedName="MyComponentName")
@Remote(MyEJBInterface.class)
public class MyEJB implements MyEJBInterface{
   public void bussinesMethod(){

   }
}

No ejb-jar.xml, jboss.xml is needed, just EJB JAR with MyEJB and MyEJBInterface compiled classes.

Now in your client code you need to lookup "MyComponentName".

dp4j has what you need. Essentially all you have to do is add dp4j to your classpath and whenever a method annotated with @Test (JUnit's annotation) calls a method that's private it will work (dp4j will inject the required reflection at compile-time). You may also use dp4j's @TestPrivates annotation to be more explicit.

If you insist on also annotating your private methods you may use Google's @VisibleForTesting annotation.

Zalgo text works because of combining characters. These are special characters that allow to modify character that comes before.

OR

y + ̆ = y̆ which actually is

y + ̆ = y̆

Since you can stack them one atop the other you can produce the following:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

which actually is:

y̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆̆

The same goes for putting stuff underneath:

In Unicode, the main block of combining diacritics for European languages and the International Phonetic Alphabet is U+0300–U+036F.

Not Bootstrap specific really... You can use inline styles or define a custom class to specify the desired "background-color".

On the other hand, Bootstrap does have a few built in background colors that have semantic meaning like "bg-success" (green) and "bg-danger" (red).

Double.MAX_VALUE is the maximum value a double can represent (somewhere around 1.7*10^308).

This should end in some calculation problems, if you try to subtract the maximum possible value of a data type.

Even though when you are dealing with money you should never use floating point values especially while rounding this can cause problems (you will either have to much or less money in your system then).

No need to re-assign.

I have a Mac, but luckily this should work the same way:

pip is a command-line thing. You don't run it in python.

For example, on my Mac, I just say:

$pip install somelib

pretty easy!

Here is the code:

public static void main(String argso[]) {
int big_array[] = new int[100000];

// Do some computations with big_array and get a result. 
int result = compute(big_array);

// We no longer need big_array. It will get garbage collected when there
// are no more references to it. Since big_array is a local variable,
// it refers to the array until this method returns. But this method
// doesn't return. So we've got to explicitly get rid of the reference
// ourselves, so the garbage collector knows it can reclaim the array. 
big_array = null;

// Loop forever, handling the user's input
for(;;) handle_input(result);
}

#include <tr1/unordered_map> will get you next-standard C++ unique hash container. Usage:

Assuming lengths of portfolio and index are the same:

Some troubleshooting tips, after I managed to waste two hours on the most trivial CORS issue:

1. If you see CORS policy execution failed logged... Don't assume that your CORS policy is not executing properly. In fact, the CORS middleware works, and your policy is executing properly. The only thing this badly worded message means is that the request's origin doesn't match any of the allowed origins (see source), i.e. the request is disallowed.

2. The origin check (as of ASP.NET Core 5.0) happens in a very simple way... i.e. case-sensitive ordinal string comparison (see source) between the strings you provided via WithOrigins() and what exists in HttpContext.Request.Headers[Origin].

3. CORS can fail if you set an allowed origin with a trailing slash /, or if it contains uppercase letters. (In my case I did in fact accidentally copy the host with a trailing slash.)

Leaving this here just in case anyone needs...

I needed to have custom domains for a Wordpress Multisite setup in IIS Express but nothing worked until I ran Webmatrix/Visual Studio as an Administrator. Then I was able to bind subdomains to the same application.

<bindings> 
    <binding protocol="http" bindingInformation="*:12345:localhost" />
    <binding protocol="http" bindingInformation="*:12345:whatever.localhost" />
</bindings>

Then going to http://whatever.localhost:12345/ will run.

I'm not sure you can change port numbers with Send-MailMessage since Gmail works on port 587. Anyway, here's how to send email through Gmail with .NET SmtpClient:

$smtpClient = New-Object system.net.mail.smtpClient
$smtpClient.Host = 'smtp.gmail.com'
$smtpClient.Port = 587
$smtpClient.EnableSsl = $true
$smtpClient.Credentials = [Net.NetworkCredential](Get-Credential GmailUserID)
$smtpClient.Send('[email protected]', '[email protected]', 'test subject', 'test message')

The following will result in a comma separated list. Be sure to include a using statement for System.Linq

List<string> ls = new List<string>();
ls.Add("one");
ls.Add("two");
string type = ls.Aggregate((x,y) => x + "," + y);

will yield one,two

if you need a space after the comma, simply change the last line to string type = ls.Aggregate((x,y) => x + ", " + y);

I think it is telling you exactly what is wrong. You cannot compare an integer with a varchar. PostgreSQL is strict and does not do any magic typecasting for you. I'm guessing SQLServer does typecasting automagically (which is a bad thing).

If you want to compare these two different beasts, you will have to cast one to the other using the casting syntax ::.

Something along these lines:

create view view1
as 
select table1.col1,table2.col1,table3.col3
from table1 
inner join
table2 
inner join 
table3
on 
table1.col4::varchar = table2.col5
/* Here col4 of table1 is of "integer" type and col5 of table2 is of type "varchar" */
/* ERROR: operator does not exist: integer = character varying */
....;

Notice the varchar typecasting on the table1.col4.

Also note that typecasting might possibly render your index on that column unusable and has a performance penalty, which is pretty bad. An even better solution would be to see if you can permanently change one of the two column types to match the other one. Literately change your database design.

Or you could create a index on the casted values by using a custom, immutable function which casts the values on the column. But this too may prove suboptimal (but better than live casting).

A Covering Index is a Non-Clustered index. Both Clustered and Non-Clustered indexes use B-Tree data structure to improve the search for data, the difference is that in the leaves of a Clustered Index a whole record (i.e. row) is stored physically right there!, but this is not the case for Non-Clustered indexes. The following examples illustrate it:

Example: I have a table with three columns: ID, Fname and Lname.

However, for a Non-Clustered index, there are two possibilities: either the table already has a Clustered index or it doesn't:

As the two diagrams show, such Non-Clustered indexes do not provide a good performance, because they cannot find the favorite value (i.e. Lname) solely from the B-Tree. Instead they have to do an extra Look Up step (either Key or RID look up) to find the value of Lname. And, this is where covered index comes to the screen. Here, the Non-Clustered index on ID coveres the value of Lname right next to it in the leaves of the B-Tree and there is no need for any type of look up anymore.

Both or and || evaluate to true if either operand is true. They evaluate their second operand only if the first is false.

As with and, the only difference between or and || is their precedence.

Just to make life interesting, and and or have the same precedence, while && has a higher precedence than ||.

composer require vendor/package:version

for example:

composer require refinery29/test-util:0.10.2

You are printing the enum object. Use the .value attribute if you wanted just to print that:

print(D.x.value)

See the Programmatic access to enumeration members and their attributes section:

If you have an enum member and need its name or value:

>>>
>>> member = Color.red
>>> member.name
'red'
>>> member.value
1

You could add a __str__ method to your enum, if all you wanted was to provide a custom string representation:

class D(Enum):
    def __str__(self):
        return str(self.value)

    x = 1
    y = 2

Demo:

>>> from enum import Enum
>>> class D(Enum):
...     def __str__(self):
...         return str(self.value)
...     x = 1
...     y = 2
... 
>>> D.x
<D.x: 1>
>>> print(D.x)
1

I believe you're looking for the @filename syntax, e.g.:

strip new lines

curl --data "@/path/to/filename" http://...

keep new lines

curl --data-binary "@/path/to/filename" http://...

curl will strip all newlines from the file. If you want to send the file with newlines intact, use --data-binary in place of --data

Try an LL suffix on the number, the compiler may be casting it to an intermediate type as part of the parse. See http://gcc.gnu.org/onlinedocs/gcc/Long-Long.html

long long int i2 = 0x0000444400004444LL;

Additionally, the the compiler is discarding the leading zeros, so 0x000044440000 is becoming 0x44440000, which is a perfectly acceptable 32-bit integer (which is why you aren't seeing any warnings prior to f2).

function check_file_path(){
    [ -f "$1" ] && return
    [ -d "$1" ] && return
    return 1
}
check_file_path $path_or_file

Surprised that we haven't seen this variation come up. This minimizes extra args on the command line and explicitly shows the DB being switched to FOO and then dropped:

$ mongo --host "mongodb://machine:port" --eval 'db.getSiblingDB("FOO").dropDatabase();'

The C++ syntax is like this:

class Bar : public Foo {
  // ...

  void printStuff() {
    Foo::printStuff(); // calls base class' function
  }
};

Updated Answer

If you are using the following Windows versions or later: Windows Server 2012, Windows Server 2012 R2, or Windows 8.1 then MakeCert is now deprecated, and Microsoft recommends using the PowerShell Cmdlet New-SelfSignedCertificate.

If you're using an older version such as Windows 7, you'll need to stick with MakeCert or another solution. Some people suggest the Public Key Infrastructure Powershell (PSPKI) Module.

Original Answer

While you can create a self-signed code-signing certificate (SPC - Software Publisher Certificate) in one go, I prefer to do the following:

Creating a self-signed certificate authority (CA)

makecert -r -pe -n "CN=My CA" -ss CA -sr CurrentUser ^
         -a sha256 -cy authority -sky signature -sv MyCA.pvk MyCA.cer

(^ = allow batch command-line to wrap line)

This creates a self-signed (-r) certificate, with an exportable private key (-pe). It's named "My CA", and should be put in the CA store for the current user. We're using the SHA-256 algorithm. The key is meant for signing (-sky).

The private key should be stored in the MyCA.pvk file, and the certificate in the MyCA.cer file.

Importing the CA certificate

Because there's no point in having a CA certificate if you don't trust it, you'll need to import it into the Windows certificate store. You can use the Certificates MMC snapin, but from the command line:

certutil -user -addstore Root MyCA.cer

Creating a code-signing certificate (SPC)

makecert -pe -n "CN=My SPC" -a sha256 -cy end ^
         -sky signature ^
         -ic MyCA.cer -iv MyCA.pvk ^
         -sv MySPC.pvk MySPC.cer

It is pretty much the same as above, but we're providing an issuer key and certificate (the -ic and -iv switches).

We'll also want to convert the certificate and key into a PFX file:

pvk2pfx -pvk MySPC.pvk -spc MySPC.cer -pfx MySPC.pfx

If you want to protect the PFX file, add the -po switch, otherwise PVK2PFX creates a PFX file with no passphrase.

Using the certificate for signing code

signtool sign /v /f MySPC.pfx ^
              /t http://timestamp.url MyExecutable.exe

(See why timestamps may matter)

If you import the PFX file into the certificate store (you can use PVKIMPRT or the MMC snapin), you can sign code as follows:

signtool sign /v /n "Me" /s SPC ^
              /t http://timestamp.url MyExecutable.exe

Some possible timestamp URLs for signtool /t are:

• http://timestamp.verisign.com/scripts/timstamp.dll
• http://timestamp.globalsign.com/scripts/timstamp.dll
• http://timestamp.comodoca.com/authenticode

• makecert
• pvk2pfx

Downloads

For those who are not .NET developers, you will need a copy of the Windows SDK and .NET framework. A current link is available here: SDK & .NET (which installs makecert in C:\Program Files\Microsoft SDKs\Windows\v7.1). Your mileage may vary.

MakeCert is available from the Visual Studio Command Prompt. Visual Studio 2015 does have it, and it can be launched from the Start Menu in Windows 7 under "Developer Command Prompt for VS 2015" or "VS2015 x64 Native Tools Command Prompt" (probably all of them in the same folder).

If we need to show different type of view in list-view then its good to use getViewTypeCount() and getItemViewType() in adapter instead of toggling a view VIEW.GONE and VIEW.VISIBLE can be very expensive task inside getView() which will affect the list scroll.

Please check this one for use of getViewTypeCount() and getItemViewType() in Adapter.

Objective-C

You can use (see NSString Class Reference)

- (id)initWithData:(NSData *)data encoding:(NSStringEncoding)encoding

Example:

NSString *myString = [[NSString alloc] initWithData:myData encoding:NSUTF8StringEncoding];

Remark: Please notice the NSData value must be valid for the encoding specified (UTF-8 in the example above), otherwise nil will be returned:

Returns nil if the initialization fails for some reason (for example if data does not represent valid data for encoding).

Prior Swift 3.0

String(data: yourData, encoding: NSUTF8StringEncoding)

Swift 3.0 Onwards

String(data: yourData, encoding: .utf8)

See String#init(data:encoding:) Reference

$(this) and this aren't the same. The first represents a jQuery object wrapped around your element. The second is just your element. The id property exists on the element, but not the jQuery object. As such, you have a few options:

1. Access the property on the element directly:

   this.id

2. Access it from the jQuery object:

   $(this).attr("id")

3. Pull the object out of jQuery:

   $(this).get(0).id; // Or $(this)[0].id

4. Get the id from the event object:

   When events are raised, for instance a click event, they carry important information and references around with them. In your code above, you have a click event. This event object has a reference to two items: currentTarget and target.

   Using target, you can get the id of the element that raised the event. currentTarget would simply tell you which element the event is currently bubbling through. These are not always the same.

   $("#button").on("click", function(e){ console.log( e.target.id ) });

Of all of these, the best option is to just access it directly from this itself, unless you're engaged in a series of nested events, then it might be best to use the event object of each nested event (give them all unique names) to reference elements in higher or lower scopes.

Try this, create drawable in your resource...

<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <solid android:color="@color/white"/>
    <size android:height="20dp"
        android:width="20dp"/>
</shape>

then use...

 Drawable mDrawable = getActivity().getResources().getDrawable(R.drawable.bg_rectangle_multicolor);
mDrawable.setColorFilter(Color.parseColor(color), PorterDuff.Mode.SRC_IN);
mView1.setBackground(mDrawable);

with color... "#FFFFFF"

if the color is transparent use... setAlpha

mView1.setAlpha(x); with x float 0-1 Ej (0.9f)

Good Luck

The one that worked for me is:

grep -e '->'

The -e means that the next argument is the pattern, and won't be interpreted as an argument.

From: http://www.linuxquestions.org/questions/programming-9/how-to-grep-for-string-769460/

sizeof(array) / sizeof(array[0])

You can also use enumerators. Every array-type of any dimension supports the Array.GetEnumerator method. The only caveat is that you will have to deal with boxing/unboxing. However, the code you need to write will be quite trivial.

Here's the sample code:

class Program
{
    static void Main(string[] args)
    {
        int[,] myArray = new int[,] { { 1, 2 }, { 3, 4 }, { 5, 6 } };
        var e = myArray.GetEnumerator();

        e.Reset();

        while (e.MoveNext())
        {
            // this will output each number from 1 to 6. 
            Console.WriteLine(e.Current.ToString());
        }

        Console.ReadLine();
    }
}

Just call: ruby your_program.rb

or

• start your program with #!/usr/bin/env ruby,
• make your file executable by running chmod +x your_program.rb
• and do ./your_program.rb some_param

You can use to_date, e.g.

> Event.last.starts_at
=> Wed, 13 Jan 2021 16:49:36.292979000 CET +01:00
> Event.last.starts_at.to_date
=> Wed, 13 Jan 2021

you can always use new stdClass(). Example code:

   $object = new stdClass();
   $object->property = 'Here we go';

   var_dump($object);
   /*
   outputs:

   object(stdClass)#2 (1) {
      ["property"]=>
      string(10) "Here we go"
    }
   */

Also as of PHP 5.4 you can get same output with:

$object = (object) ['property' => 'Here we go'];

You will have to annotate your service with @Service since you have said I am using annotations for mapping

W3Schools is your friend: http://www.w3schools.com/php/func_filesystem_fgets.asp

And here: http://php.net/manual/en/function.fopen.php has more info on fopen including what the modes are.

What W3Schools says:

<?php
$file = fopen("test.txt","r");

while(! feof($file))
  {
  echo fgets($file). "<br />";
  }

fclose($file);
?> 

fopen opens the file (in this case test.txt with mode 'r' which means read-only and places the pointer at the beginning of the file)

The while loop tests to check if it's at the end of file (feof) and while it isn't it calls fgets which gets the current line where the pointer is.

Continues doing this until it is the end of file, and then closes the file.

Using C++ in MS Visual Studio 2015 (14), I use:

#include <chrono>

string NowToString()
{
  chrono::system_clock::time_point p = chrono::system_clock::now();
  time_t t = chrono::system_clock::to_time_t(p);
  char str[26];
  ctime_s(str, sizeof str, &t);
  return str;
}

Functor can also be used to simulate defining a local function within a function. Refer to the question and another.

But a local functor can not access outside auto variables. The lambda (C++11) function is a better solution.

GoodNews from v.9.6 and above, View editing are now native from psql. Just invoke \ev command. View definitions will show in your configured editor.

julian@assange=# \ev {your_view_names}

Bonus. Some useful command to interact with query buffer.

Query Buffer
  \e [FILE] [LINE]       edit the query buffer (or file) with external editor
  \ef [FUNCNAME [LINE]]  edit function definition with external editor
  \ev [VIEWNAME [LINE]]  edit view definition with external editor
  \p                     show the contents of the query buffer
  \r                     reset (clear) the query buffer
  \s [FILE]              display history or save it to file
  \w FILE                write query buffer to file

right way is

import datetime
isinstance(x, datetime.date)

When I try this on my machine it works fine. You need to look into why datetime.date is not a class. Are you perhaps masking it with something else? or not referencing it correctly for your import?

For viewers who got this error after upgrading React Native to 0.40+, you may need to run react-native upgrade on the command line.

In Java 8

To create a non-empty list of fixed size (operations like add, remove, etc., are not supported):

List<Integer> list = Arrays.asList(1, 2); // but, list.set(...) is supported

To create a non-empty mutable list:

List<Integer> list = new ArrayList<>(Arrays.asList(3, 4));

In Java 9

Using a new List.of(...) static factory methods:

List<Integer> immutableList = List.of(1, 2);

List<Integer> mutableList = new ArrayList<>(List.of(3, 4));

In Java 10

Using the Local Variable Type Inference:

var list1 = List.of(1, 2);

var list2 = new ArrayList<>(List.of(3, 4));

var list3 = new ArrayList<String>();

And follow best practices...

Don't use raw types

Since Java 5, generics have been a part of the language - you should use them:

List<String> list = new ArrayList<>(); // Good, List of String

List list = new ArrayList(); // Bad, don't do that!

Program to interfaces

For example, program to the List interface:

List<Double> list = new ArrayList<>();

Instead of:

ArrayList<Double> list = new ArrayList<>(); // This is a bad idea!

I will suggest you to use ClientID of HiddenField. first Register its client Id in any Javascript Variable from codebehind, then use it in clientside script. as:

.cs file code:

ClientScript.RegisterStartupScript(this.GetType(), "clientids", "var hdntxtbxTaksit=" + hdntxtbxTaksit.ClientID, true);

and then use following code in JS:

document.getElementById(hdntxtbxTaksit).value= ""; 

In Sql Server:

insert into Table_Name(PersonName,PersonEmail) values(NULL,'[email protected]')

PersonName is varchar(50), NULL is not a string, because we are not passing with in single codes, so it treat as NULL.

Code Behind:

string name = (txtName.Text=="")? NULL : "'"+ txtName.Text +"'";
string email = txtEmail.Text;

insert into Table_Name(PersonName,PersonEmail) values(name,'"+email+"')

var filename = $('input[type=file]').val().split('\\').pop();

or you could just do (because it's always C:\fakepath that is added for security reasons):

var filename = $('input[type=file]').val().replace(/C:\\fakepath\\/i, '')

This approach is not correct beacuse of Google Server Overload. For more informations see https://gis.stackexchange.com/questions/15052/how-to-avoid-google-map-geocode-limit#answer-15365

By the way, if you wish to proceed anyway, here you can find a code that let you load multiple markers ajax sourced on google maps avoiding OVER_QUERY_LIMIT error.

I've tested on my onw server and it works!:

'O' stands for object.

#Loading a csv file as a dataframe
import pandas as pd 
train_df = pd.read_csv('train.csv')
col_name = 'Name of Employee'

#Checking the datatype of column name
train_df[col_name].dtype

#Instead try printing the same thing
print train_df[col_name].dtype

The first line returns: dtype('O')

The line with the print statement returns the following: object

Yes of course, just add the response y as first column in the dataframe and call lm() on it:

d2<-data.frame(y,d)
> d2
  y x1 x2 x3
1 1  4  3  4
2 4 -1  9 -4
3 6  3  8 -2
> lm(d2)

Call:
lm(formula = d2)

Coefficients:
(Intercept)           x1           x2           x3  
    -5.6316       0.7895       1.1579           NA  

Also, my information about R points out that assignment with <- is recommended over =.

My suggestion would be to finish the activity that you don't want the users to go back to. For instance, in your sign in activity, right after you call startActivity, call finish(). When the users hit the back button, they will not be able to go to the sign in activity because it has been killed off the stack.

You could loop through DataGridView using Rows property, like:

foreach (DataGridViewRow row in datagridviews.Rows)
{
   currQty += row.Cells["qty"].Value;
   //More code here
}

There's no difference, == is a synonym for = (for the C/C++ people, I assume). See here, for example.

You could double-check just to be really sure or just for your interest by looking at the bash source code, should be somewhere in the parsing code there, but I couldn't find it straightaway.

I had an quite unusual case of this error, but maybe someone would benefit from it.

I had this error with missing .dll file of one of projects in solution (with target framework netstandard 2.0) I'm working on and at once error with reference (to Microsoft.Office.Interop.Word) this project uses.

This solution was cloned from git repository, and same solution compiled well for other people in my team.

I tried every propsed solution for issue - restarting VS, computer; cleaning project; checking and unchecking build checkboxes; checking if build order is proper etc.

I figured out that manifest of this project was not selected by default (dropdown of manifest in project properties was empty and disabled). Therefore I tried to add it, but nothing worked.

At last I started comparing this project .csproj file with one in other, older version of this project, which compiled without problem. After a bit of usless tries I figured out, that path to Microsoft.Office.Interop.Word is the same in both projects, even thought it was a relative path starting with lots of "go up" symbols ( ..\ ). And not working project was one level lower than other.

Adding one more "go up" symbol ( ..\ ) in reference path to Microsoft.Office.Interop.Word inside project .csproj file solved the issue.

I have no idea why this path was created that way and doesn't update in my case, while it work properly for others in my team.

Just a simple line of code in the head section can refresh the page

although its not a javascript function, its the simplest way to accomplish the above task hopefully.

There is the data.table approach for an inner join, which is very time and memory efficient (and necessary for some larger data.frames):

library(data.table)

dt1 <- data.table(df1, key = "CustomerId") 
dt2 <- data.table(df2, key = "CustomerId")

joined.dt1.dt.2 <- dt1[dt2]

merge also works on data.tables (as it is generic and calls merge.data.table)

merge(dt1, dt2)

data.table documented on stackoverflow:
How to do a data.table merge operation
Translating SQL joins on foreign keys to R data.table syntax
Efficient alternatives to merge for larger data.frames R
How to do a basic left outer join with data.table in R?

Yet another option is the join function found in the plyr package

library(plyr)

join(df1, df2,
     type = "inner")

#   CustomerId Product   State
# 1          2 Toaster Alabama
# 2          4   Radio Alabama
# 3          6   Radio    Ohio

Options for type: inner, left, right, full.

From ?join: Unlike merge, [join] preserves the order of x no matter what join type is used.

Alex mentioned memory efficiency, and Roberto mentions convenience, and these are both good points. For a few more ideas, I'll mention speed and functionality.

Functionality: You get a lot built in with NumPy, FFTs, convolutions, fast searching, basic statistics, linear algebra, histograms, etc. And really, who can live without FFTs?

Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).

from numpy import arange
from timeit import Timer

Nelements = 10000
Ntimeits = 10000

x = arange(Nelements)
y = range(Nelements)

t_numpy = Timer("x.sum()", "from __main__ import x")
t_list = Timer("sum(y)", "from __main__ import y")
print("numpy: %.3e" % (t_numpy.timeit(Ntimeits)/Ntimeits,))
print("list:  %.3e" % (t_list.timeit(Ntimeits)/Ntimeits,))

which on my systems (while I'm running a backup) gives:

numpy: 3.004e-05
list:  5.363e-04

For people facing this issue in the Android Studio beta, the accepted answer didn't solve my problem. Importing a project downloaded from GitHub, I had the following in my build.gradle file of app giving an error in question:

 dependencies {
    compile 'com.android.support:support-v4:+'
}

But in my external library folder I have this folder:

support-v4-21.0.0-rc1 //note the 21

I solved the above problem by changing the dependency to:

dependencies {
compile 'com.android.support:support-v4:20.+' //20 used less than available strange but works
}

Note: you might also need to download api level lower than the currently available in Android Studio for some library and projects for this to work properly.

There is an API that's called SubnetTree available in python that do this job very well. This is a simple example :

import SubnetTree
t = SubnetTree.SubnetTree()
t.insert("10.0.1.3/32")
print("10.0.1.3" in t)

This is the link

If you want to stick with the same sort of loop then this will work:

Option Explicit

Sub selectColumns()

Dim topSelection As Integer
Dim endSelection As Integer
topSelection = 2
endSelection = 10

Dim columnSelected As Integer
columnSelected = 1
Do
   With Excel.ThisWorkbook.ActiveSheet
        .Range(.Cells(columnSelected, columnSelected), .Cells(endSelection, columnSelected)).Select
   End With
   columnSelected = columnSelected + 1
Loop Until columnSelected > 10

End Sub

EDIT

If in reality you just want to loop through every cell in an area of the spreadsheet then use something like this:

Sub loopThroughCells()

'=============
'this is the starting point
Dim rwMin As Integer
Dim colMin As Integer
rwMin = 2
colMin = 2
'=============

'=============
'this is the ending point
Dim rwMax As Integer
Dim colMax As Integer
rwMax = 10
colMax = 5
'=============

'=============
'iterator
Dim rwIndex As Integer
Dim colIndex As Integer
'=============

For rwIndex = rwMin To rwMax
        For colIndex = colMin To colMax
            Cells(rwIndex, colIndex).Select
        Next colIndex
Next rwIndex

End Sub

There are many ways to do this. To fix your current code using %-formatting, you need to pass in a tuple:

1. Pass it as a tuple:

   print("Total score for %s is %s" % (name, score))
   

A tuple with a single element looks like ('this',).

Here are some other common ways of doing it:

2. Pass it as a dictionary:

   print("Total score for %(n)s is %(s)s" % {'n': name, 's': score})
   

There's also new-style string formatting, which might be a little easier to read:

3. Use new-style string formatting:

   print("Total score for {} is {}".format(name, score))
   

4. Use new-style string formatting with numbers (useful for reordering or printing the same one multiple times):

   print("Total score for {0} is {1}".format(name, score))
   

5. Use new-style string formatting with explicit names:

   print("Total score for {n} is {s}".format(n=name, s=score))
   

6. Concatenate strings:

   print("Total score for " + str(name) + " is " + str(score))
   

The clearest two, in my opinion:

7. Just pass the values as parameters:

   print("Total score for", name, "is", score)
   

   If you don't want spaces to be inserted automatically by print in the above example, change the sep parameter:

   print("Total score for ", name, " is ", score, sep='')
   

   If you're using Python 2, won't be able to use the last two because print isn't a function in Python 2. You can, however, import this behavior from __future__:

   from __future__ import print_function
   

8. Use the new f-string formatting in Python 3.6:

   print(f'Total score for {name} is {score}')
   

terminal 1

dd if=/dev/sda of=debian.img

terminal 2

killall -SIGUSR1 dd

go back to terminal 1

On Mac OS X (MBP), the following (taken from another answer found herein) resolved my issues:

C02L257NDV33:~ jjohnson$ brew install pip
Error: No available formula for pip
Homebrew provides pip via: `brew install python`. However you will then
have two Pythons installed on your Mac, so alternatively you can:
    sudo easy_install pip
C02L257NDV33:~ jjohnson$ sudo easy_install pip

Clearly the root cause here is having a secondary method by which to install python (in my case Homebrew). Hopefully, the people responsible for the pip script can remedy this issue since its still relevant 2 years after first being reported on Stack Overflow.

You don't require broadcast receiver. If one would take some pain copy one of the api(serviceconnection) from above example by Stephen Donecker and paste it in google you would get this, https://www.concretepage.com/android/android-local-bound-service-example-with-binder-and-serviceconnection

I would say not possible in most browsers, at least not without some additional plugins. And in any case I would try to avoid relying on the browser's zoom as the implementations vary (some browsers only zoom the fonts, others zoom the images, too etc). Unless you don't care much about user experience.

If you need a more reliable zoom, then consider zooming the page fonts and images with JavaScript and CSS, or possibly on the server side. The image and layout scaling issues could be addressed this way. Of course, this requires a bit more work.

This worked for me. I have many targets that have different controllers so previous answers didn't seemed to work.

first you want this inside your AppDelegate class:

var window: UIWindow?

then, in your function

let navigationController = window?.rootViewController as? UINavigationController
if let activeController = navigationController!.visibleViewController {
    if activeController.isKindOfClass( MyViewController )  {
        println("I have found my controller!")    
   }
}

I found this answer on a Google forum that has worked me. In the footnotes it mentions 'googleapps.exe' - I don't have this and it has still worked. Simply follow the instructions below but close down all applications before making changes to the Registry. Also I saved the existing value just in case it didn't work.

Simply type "run" in your search bar, then type "regedit" then travel to:

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\mailto\shell\open\command\ 

edit (double click) "(Default)" to:

"C:\Program Files (x86)\Google\Google Apps\googleapps.exe" --domain= --mailto.google.com="%1" 

That's it! Save and close it and it should work beautifully!

Using this method prevents you from having to download the GMail Notifier, which for those of us with GTalk don't need since it does it for us. I'm not sure why Google can't solve this issue easily.. i've heard Google Apps haven't been tested fully on Windows 7 but it's obvious the same tag works with it.

Note: The only thing with this solution is you need to have the googleapps.exe file on your machine. I believe I got it with my free GooglePack from their site which has now been discontinued. I tried searching the net for a way to download it but weirdly enough it seems it's reserved only for Businesses now and there is no download link available from the web because everyone who has it streamed it using the google updater.. Odd. Anyway good luck!

Building on what Jon of All Trades has provided, the following (~n) removed the pesky double extension issue: FOR /f "delims=" %%i IN ('DIR *.xlsx /b') DO ExcelToCSV.vbs "%%i" "%%~ni.csv"

Pretty late response but you can do the following in Kotlin:

activity?.applicationContext?.let { SymptomsAdapters(it, param2, param3, ...) }

(?.) is for safe null operation to prevent from the null pointer exception.

You do not want to create a new context as that can lead to memory leaks when interchanging between fragments or when the device changes rotation.

And as someone mentioned above, in Java you can obtain context in a fragment by doing the following:

getActivity().getApplicationContext()
