In order to simplify your life you can extend the HTMLElement object. It might not work for older browsers, but definitely makes your life easier:

HTMLElement = typeof(HTMLElement) != 'undefined' ? HTMLElement : Element;

HTMLElement.prototype.prepend = function(element) {
    if (this.firstChild) {
        return this.insertBefore(element, this.firstChild);
    } else {
        return this.appendChild(element);
    }
};

So next time you can do this:

document.getElementById('container').prepend(document.getElementById('block'));
// or
var element = document.getElementById('anotherElement');
document.body.prepend(div);

list[:10]

will give you the first 10 elements of this list using slicing.

However, note, it's best not to use list as a variable identifier as it's already used by Python: list()

To find out more about these type of operations you might find this tutorial on lists helpful and the link @DarenThomas provided Explain Python's slice notation - thanks Daren)

Here there is an explanation: http://bytes.com/topic/python/answers/444733-why-there-no-post-pre-increment-operator-python

However the absence of this operator is in the python philosophy increases consistency and avoids implicitness.

In addition, this kind of increments are not widely used in python code because python have a strong implementation of the iterator pattern plus the function enumerate.

As of October 2014:

For latest remote version:

npm view <module_name> version  

Note, version is singular.

If you'd like to see all available (remote) versions, then do:

npm view <module_name> versions

Note, versions is plural. This will give you the full listing of versions to choose from.

To get the version you actually have locally you could use:

npm list --depth=0 | grep <module_name>

Note, even with package.json declaring your versions, the installed version might actually differ slightly - for instance if tilda was used in the version declaration

Should work across NPM versions 1.3.x, 1.4.x, 2.x and 3.x

Building PhoneGap Android app for deployment to the Google Play Store

These steps would work for Cordova, PhoneGap or Ionic. The only difference would be, wherever a call to cordova is placed, replace it with phonegap or ionic, for your particular scenario.

Once you are done with the development and are ready to deploy, follow these steps:

1. Open a command line window (Terminal on macOS and Linux OR Command Prompt on Windows).

2. Head over to the /path/to/your/project/, which we would refer to as the Project Root.
   
   

3. While at the project root, remove the "Console" plugin from your set of plugins.
   
   The command is: cordova plugin rm cordova-plugin-console
   
   

4. While still at the project root, use the cordova build command to create an APK for release distribution.
   
   The command is: cordova build --release android
   
   

5. The above process creates a file called android-release-unsigned.apk in the folder ProjectRoot/platforms/android/build/outputs/apk/
   
   

6. Sign and align the APK using the instructions at https://developer.android.com/studio/publish/app-signing.html#signing-manually
   
   At the end of this step the APK which you get can be uploaded to the Play Store.
   
   

Note: As a newbie or a beginner, the last step may be a bit confusing as it was to me. One may run into a few issues and may have some questions as to what these commands are and where to find them.

Q1. What are jarsigner and keytool?
Ans: The Android App Signing instructions do tell you specifically what jarsigner and keytool are all about BUT it doesn't tell you where to find them if you run into a 'command not found error' on the command line window.

Thus, if you've got the Java Development Kit(JDK) added to your PATH variable, simply running the commands as in the Guide would work. BUT, if you don't have it in your PATH, you can always access them from the bin folder of your JDK installation.

Q2. Where is zipalign?
Ans: There is a high probability to not find the zipalign command and receive the 'command not found error'. You'd probably be googling zipalign and where to find it?

The zipalign utility is present within the Android SDK installation folder. On macOS, the default location is at, user-name/Library/Android/sdk/. If you head over to the folder you would find a bunch of other folders like docs, platform-tools, build-tools, tools, add-ons...

Open the build-tools folder. cd build-tools. In here, there would be a number of folders which are versioned according to the build tool-chain you are using in the Android SDK Manager. ZipAlign is available in each of these folders. I personally go for the folder with the latest version on it. Open Any.

On macOS or Linux you may have to use ./zipalign rather than simply typing in zipalign as the documentation mentions. On Windows, zipalign is good enough.

No there isn't and it's probably not there, because there are very few valid uses for it. I would think twice before using it. Also, it is indeed easy to create yourself.

Please refer to this discussion about why it's even in .NET.

I guess UnsupportedOperationException comes close, although it doesn't say the operation is just not implemented, but unsupported even. That could imply no valid implementation is possible. Why would the operation be unsupported? Should it even be there? Interface segregation or Liskov substitution issues maybe?

If it's work in progress I'd go for ToBeImplementedException, but I've never caught myself defining a concrete method and then leave it for so long it makes it into production and there would be a need for such an exception.

If you want to format it with manually set symbols, use this:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(',');
DecimalFormat decimalFormat = new DecimalFormat("#,##0.00", decimalFormatSymbols);
System.out.println(decimalFormat.format(1237516.2548)); //1,237,516.25

Locale-based formatting is preferred, though.

Use PropertyInfo.PropertyType to get the type of the property.

public bool ValidateData(object data)
{
    foreach (PropertyInfo propertyInfo in data.GetType().GetProperties())
    {
        if (propertyInfo.PropertyType == typeof(string))
        {
            string value = propertyInfo.GetValue(data, null);

            if value is not OK
            {
                return false;
            }
        }
    }            

    return true;
}

I understand this question might have a React-specific cause, but it shows up first in search results for "Typeerror: Failed to fetch" and I wanted to lay out all possible causes here.

The Fetch spec lists times when you throw a TypeError from the Fetch API: https://fetch.spec.whatwg.org/#fetch-api

Relevant passages as of January 2021 are below. These are excerpts from the text.

4.6 HTTP-network fetch

To perform an HTTP-network fetch using request with an optional credentials flag, run these steps:
...
16. Run these steps in parallel:
...
2. If aborted, then:
...
3. Otherwise, if stream is readable, error stream with a TypeError.

To append a name/value name/value pair to a Headers object (headers), run these steps:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If headers’s guard is "immutable", then throw a TypeError.

Filling Headers object headers with a given object object:

To fill a Headers object headers with a given object object, run these steps:

1. If object is a sequence, then for each header in object:
   1. If header does not contain exactly two items, then throw a TypeError.

Method steps sometimes throw TypeError:

The delete(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. If this’s guard is "immutable", then throw a TypeError.

The get(name) method steps are:

1. If name is not a name, then throw a TypeError.
2. Return the result of getting name from this’s header list.

The has(name) method steps are:

1. If name is not a name, then throw a TypeError.

The set(name, value) method steps are:

1. Normalize value.
2. If name is not a name or value is not a value, then throw a TypeError.
3. If this’s guard is "immutable", then throw a TypeError.

To extract a body and a Content-Type value from object, with an optional boolean keepalive (default false), run these steps:
...
5. Switch on object:
...
ReadableStream
If keepalive is true, then throw a TypeError.
If object is disturbed or locked, then throw a TypeError.

In the section "Body mixin" if you are using FormData there are several ways to throw a TypeError. I haven't listed them here because it would make this answer very long. Relevant passages: https://fetch.spec.whatwg.org/#body-mixin

In the section "Request Class" the new Request(input, init) constructor is a minefield of potential TypeErrors:

The new Request(input, init) constructor steps are:
...
6. If input is a string, then:
...
2. If parsedURL is a failure, then throw a TypeError.
3. IF parsedURL includes credentials, then throw a TypeError.
...
11. If init["window"] exists and is non-null, then throw a TypeError.
...
15. If init["referrer" exists, then:
...
1. Let referrer be init["referrer"].
2. If referrer is the empty string, then set request’s referrer to "no-referrer".
3. Otherwise:
1. Let parsedReferrer be the result of parsing referrer with baseURL.
2. If parsedReferrer is failure, then throw a TypeError.
...
18. If mode is "navigate", then throw a TypeError.
...
23. If request's cache mode is "only-if-cached" and request's mode is not "same-origin" then throw a TypeError.
...
27. If init["method"] exists, then:
...
2. If method is not a method or method is a forbidden method, then throw a TypeError.
...
32. If this’s request’s mode is "no-cors", then:
1. If this’s request’s method is not a CORS-safelisted method, then throw a TypeError.
...
35. If either init["body"] exists and is non-null or inputBody is non-null, and request’s method is GET or HEAD, then throw a TypeError.
...
38. If body is non-null and body's source is null, then:
1. If this’s request’s mode is neither "same-origin" nor "cors", then throw a TypeError.
...
39. If inputBody is body and input is disturbed or locked, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In the Response class:

The new Response(body, init) constructor steps are:
...
2. If init["statusText"] does not match the reason-phrase token production, then throw a TypeError.
...
8. If body is non-null, then:
1. If init["status"] is a null body status, then throw a TypeError.
...

The static redirect(url, status) method steps are:
...
2. If parsedURL is failure, then throw a TypeError.

The clone() method steps are:

1. If this is disturbed or locked, then throw a TypeError.

In section "The Fetch method"

The fetch(input, init) method steps are:
...
9. Run the following in parallel:
To process response for response, run these substeps:
...
3. If response is a network error, then reject p with a TypeError and terminate these substeps.

In addition to these potential problems, there are some browser-specific behaviors which can throw a TypeError. For instance, if you set keepalive to true and have a payload > 64 KB you'll get a TypeError on Chrome, but the same request can work in Firefox. These behaviors aren't documented in the spec, but you can find information about them by Googling for limitations for each option you're setting in fetch.

One thing missing here: if you have a varying number of elements that you want to put together to something like

WHERE [...] AND (field LIKE '%abc%' OR field LIKE '%def%')

and dont want to assemble a DQL-String yourself, you can use the orX mentioned above like this:

$patterns = ['abc', 'def'];
$orStatements = $qb->expr()->orX();
foreach ($patterns as $pattern) {
    $orStatements->add(
        $qb->expr()->like('field', $qb->expr()->literal('%' . $pattern . '%'))
    );
}
$qb->andWhere($orStatements);

This is one solution, though since APIs change over time and there may be other ways of doing it, make sure to check the other answers. One claims to be faster, and another claims to be easier.

private int getRelativeLeft(View myView) {
    if (myView.getParent() == myView.getRootView())
        return myView.getLeft();
    else
        return myView.getLeft() + getRelativeLeft((View) myView.getParent());
}

private int getRelativeTop(View myView) {
    if (myView.getParent() == myView.getRootView())
        return myView.getTop();
    else
        return myView.getTop() + getRelativeTop((View) myView.getParent());
}

Let me know if that works.

It should recursively just add the top and left positions from each parent container. You could also implement it with a Point if you wanted.

I had problems using pdftk with the cat parameter had a better success with output.

The following command worked for me:

pdftk file_1.pdf file_1.pdf file_1.pdf file_1.pdf cat output.pdf

Using cat produced the following error:

Error: Unexpected text in page range end, here: 
    output.pdf
    Exiting.
    Acceptable keywords, for example: "even" or "odd".
    To rotate pages, use: "north" "south" "east"
        "west" "left" "right" or "down"
Errors encountered.  No output created.
Done.  Input errors, so no output created.

I created a 172mb PDF is no time at all.

.prop('disabled') will return a Boolean:

var isDisabled = $('textbox').prop('disabled');

Here's the fiddle: http://jsfiddle.net/unhjM/

If you want to make sure your div is not visible by default use ng-cloak class instead. It will work properly with ngShow directive:

<div><div ng-show="myvalue" class="ng-cloak">Here I am</div></div>

Demo: http://jsfiddle.net/4WK7R/4/

You should never use select(), or text(), or radio() etc.; it's terrible practice. You should use input():

$form->input('tree_id', array('options' => $trees));

Then in the controller:

$this->data['Leaf']['tree_id'] = $id;

class a(object):
    def my_hello(self):
        print "hello ravi"

class b(a):
    def my_hello(self):
    super(b,self).my_hello()
    print "hi"

obj = b()
obj.my_hello()

The previous answers did not work for me, but this did:

docker stop $(docker ps -q --filter ancestor=<image-name> )

Just create a class or structure that has two members, one List(Of OneItem) and the other Integer and send in an instance of that class.

Edit: Sorry, missed that you had problems with one parameter as well. Just look at Thread Constructor (ParameterizedThreadStart) and that page includes a simple sample.

I cleared this use. By using this site click Here , follow the steps, the same steps follows upto the ubuntu version 18.04

That is because you are only checking the current checkbox.

Change it to

function checkUncheck() { 
    $('.pChk').click(function() {
        if ( $('.pChk:checked').length > 0) {
            $("#ProjectListButton").show();
        } else {
            $("#ProjectListButton").hide();
        }
    }); 
}

to check if any of the checkboxes is checked (lots of checks in this line..).

Look into System.Threading.Timer class. I think this is what you're looking for.

The code example on MSDN seems to show this class doing very similar to what you're trying to do (check status after certain time).

The mentioned code example from the MSDN link:

using System;
using System.Threading;

class TimerExample
{
    static void Main()
    {
        // Create an AutoResetEvent to signal the timeout threshold in the
        // timer callback has been reached.
        var autoEvent = new AutoResetEvent(false);
        
        var statusChecker = new StatusChecker(10);

        // Create a timer that invokes CheckStatus after one second, 
        // and every 1/4 second thereafter.
        Console.WriteLine("{0:h:mm:ss.fff} Creating timer.\n", 
                        DateTime.Now);
        var stateTimer = new Timer(statusChecker.CheckStatus, 
                                autoEvent, 1000, 250);

        // When autoEvent signals, change the period to every half second.
        autoEvent.WaitOne();
        stateTimer.Change(0, 500);
        Console.WriteLine("\nChanging period to .5 seconds.\n");

        // When autoEvent signals the second time, dispose of the timer.
        autoEvent.WaitOne();
        stateTimer.Dispose();
        Console.WriteLine("\nDestroying timer.");
    }
}

class StatusChecker
{
    private int invokeCount;
    private int  maxCount;

    public StatusChecker(int count)
    {
        invokeCount  = 0;
        maxCount = count;
    }

    // This method is called by the timer delegate.
    public void CheckStatus(Object stateInfo)
    {
        AutoResetEvent autoEvent = (AutoResetEvent)stateInfo;
        Console.WriteLine("{0} Checking status {1,2}.", 
            DateTime.Now.ToString("h:mm:ss.fff"), 
            (++invokeCount).ToString());

        if(invokeCount == maxCount)
        {
            // Reset the counter and signal the waiting thread.
            invokeCount = 0;
            autoEvent.Set();
        }
    }
}
// The example displays output like the following:
//       11:59:54.202 Creating timer.
//       
//       11:59:55.217 Checking status  1.
//       11:59:55.466 Checking status  2.
//       11:59:55.716 Checking status  3.
//       11:59:55.968 Checking status  4.
//       11:59:56.218 Checking status  5.
//       11:59:56.470 Checking status  6.
//       11:59:56.722 Checking status  7.
//       11:59:56.972 Checking status  8.
//       11:59:57.223 Checking status  9.
//       11:59:57.473 Checking status 10.
//       
//       Changing period to .5 seconds.
//       
//       11:59:57.474 Checking status  1.
//       11:59:57.976 Checking status  2.
//       11:59:58.476 Checking status  3.
//       11:59:58.977 Checking status  4.
//       11:59:59.477 Checking status  5.
//       11:59:59.977 Checking status  6.
//       12:00:00.478 Checking status  7.
//       12:00:00.980 Checking status  8.
//       12:00:01.481 Checking status  9.
//       12:00:01.981 Checking status 10.
//       
//       Destroying timer.

It looks like not.

Put a breakpoint, when it stops switch to the console, try to set the variable. It does not error when you assign it a different value, but if you read it after the assignment, it's unmodified. :-/

The problem is an issue of semantic meaning (as BoltClock mentions) and visual rendering.

Originally HTML used <b> and <i> for these purposes, entirely stylistic commands, laid down in the semantic environment of the document markup. CSS is an attempt to separate out as far as possible the stylistic elements of the medium. Thus style information such as bold and italics should go in CSS.

<strong> and <em> were introduced to fill the semantic need for text to be marked as more important or stressed. They have default stylistic interpretations akin to bold and italic, but they are not bound to that fate.

The noConflict() method releases the $ shortcut identifier, so that other scripts can use it for next time.

Default jquery $ as:

// Actin  with $
$(function(){
    $(".add").hide();
    $(".add2").show();
});

Or as custom:

var j = jQuery.noConflict();
 // Action with j
j(function(){
    j(".edit").hide();
    j(".add2").show();
});

jQuery provides that:

if ($.browser.webkit){
    ...
}

Update

As noted in other answers/comments, it's always better to check for feature support than agent info. jQuery also provides an object for that: jQuery.support. Check the documentation to see the detailed list features to check for.

You can use the for command:

FOR /F "eol=; tokens=2,3* delims=, " %i in (myfile.txt) do @echo %i %j %k

Type

for /?

at the command prompt. Also, you can parse ini files!

Depending on your timezone, you may lose a few minutes (1650-01-01 00:00:00 becomes 1649-12-31 23:52:58)

Use the following code to avoid that

new Timestamp(localDateTime.getYear() - 1900, localDateTime.getMonthOfYear() - 1, localDateTime.getDayOfMonth(), localDateTime.getHourOfDay(), localDateTime.getMinuteOfHour(), localDateTime.getSecondOfMinute(), fractional);

HTTP does not support more than one file download at once.

There are two solutions:

• Open x amount of windows to initiate the file downloads (this would be done with JavaScript)
• preferred solution create a script to zip the files

Font.Name, Font.XYZProperty, etc are readonly as Font is an immutable object, so you need to specify a new Font object to replace it:

mainForm.lblName.Font = new Font("Arial", mainForm.lblName.Font.Size);

Check the constructor of the Font class for further options.

If you want to learn your data summary (df) provides the min, 1st quantile, median and mean, 3rd quantile and max of numerical columns and the frequency of the top levels of the factor columns.

Edit:

Android 5.0 (API level 21) and higher uses ART which supports multidexing. Therefore, if your minSdkVersion is 21 or higher, the multidex support library is not needed.

Modify your build.gradle:

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.0"

         defaultConfig {
             minSdkVersion 14 //lower than 14 doesn't support multidex
             targetSdkVersion 22

             // Enabling multidex support.
             multiDexEnabled true
         }
}

dependencies {
    implementation 'com.android.support:multidex:1.0.3'
}

If you are running unit tests, you will want to include this in your Application class:

public class YouApplication extends Application {

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }

}

Or just make your application class extend MultiDexApplication

public class Application extends MultiDexApplication {

}

For more info, this is a good guide.

Basically, if you specify a files parameter (a dictionary), then requests will send a multipart/form-data POST instead of a application/x-www-form-urlencoded POST. You are not limited to using actual files in that dictionary, however:

>>> import requests
>>> response = requests.post('http://httpbin.org/post', files=dict(foo='bar'))
>>> response.status_code
200

and httpbin.org lets you know what headers you posted with; in response.json() we have:

>>> from pprint import pprint
>>> pprint(response.json()['headers'])
{'Accept': '*/*',
 'Accept-Encoding': 'gzip, deflate',
 'Connection': 'close',
 'Content-Length': '141',
 'Content-Type': 'multipart/form-data; '
                 'boundary=c7cbfdd911b4e720f1dd8f479c50bc7f',
 'Host': 'httpbin.org',
 'User-Agent': 'python-requests/2.21.0'}

Better still, you can further control the filename, content type and additional headers for each part by using a tuple instead of a single string or bytes object. The tuple is expected to contain between 2 and 4 elements; the filename, the content, optionally a content type, and an optional dictionary of further headers.

I'd use the tuple form with None as the filename, so that the filename="..." parameter is dropped from the request for those parts:

>>> files = {'foo': 'bar'}
>>> print(requests.Request('POST', 'http://httpbin.org/post', files=files).prepare().body.decode('utf8'))
--bb3f05a247b43eede27a124ef8b968c5
Content-Disposition: form-data; name="foo"; filename="foo"

bar
--bb3f05a247b43eede27a124ef8b968c5--
>>> files = {'foo': (None, 'bar')}
>>> print(requests.Request('POST', 'http://httpbin.org/post', files=files).prepare().body.decode('utf8'))
--d5ca8c90a869c5ae31f70fa3ddb23c76
Content-Disposition: form-data; name="foo"

bar
--d5ca8c90a869c5ae31f70fa3ddb23c76--

files can also be a list of two-value tuples, if you need ordering and/or multiple fields with the same name:

requests.post(
    'http://requestb.in/xucj9exu',
    files=(
        ('foo', (None, 'bar')),
        ('foo', (None, 'baz')),
        ('spam', (None, 'eggs')),
    )
)

If you specify both files and data, then it depends on the value of data what will be used to create the POST body. If data is a string, only it willl be used; otherwise both data and files are used, with the elements in data listed first.

There is also the excellent requests-toolbelt project, which includes advanced Multipart support. It takes field definitions in the same format as the files parameter, but unlike requests, it defaults to not setting a filename parameter. In addition, it can stream the request from open file objects, where requests will first construct the request body in memory:

from requests_toolbelt.multipart.encoder import MultipartEncoder

mp_encoder = MultipartEncoder(
    fields={
        'foo': 'bar',
        # plain file object, no filename or mime type produces a
        # Content-Disposition header with just the part name
        'spam': ('spam.txt', open('spam.txt', 'rb'), 'text/plain'),
    }
)
r = requests.post(
    'http://httpbin.org/post',
    data=mp_encoder,  # The MultipartEncoder is posted as data, don't use files=...!
    # The MultipartEncoder provides the content-type header with the boundary:
    headers={'Content-Type': mp_encoder.content_type}
)

Fields follow the same conventions; use a tuple with between 2 and 4 elements to add a filename, part mime-type or extra headers. Unlike the files parameter, no attempt is made to find a default filename value if you don't use a tuple.

But it would be possible if one were used in place of the variable in @html.Hidden field. As in this example.

@Html.Hidden("myVar", 0);

set the field per script:

<script>
function setMyValue(value) {
     $('#myVar').val(value);       
}
</script>

I hope I can at least offer no small Workaround.

hey I understand this is an old thread but I have a query in regards to apachebenchmarking. how do you collect the metrics from apache benchmarking. P.S: I have to do it via telegraf and put it to influxdb . any suggestions/advice/help would be appreciated. Thanks a ton.

Another option would be to use the File Explorer in DDMS (Eclipse SDK), you can see the whole file system there and download/upload files to the desired place. That way you don't have to mount and deal with images. Just remember to set your device as USB debuggable (from Developer Tools)

you can add the Path to coinhsl lib to LD_LIBRARY_PATH variable. May be that will help.

export LD_LIBRARY_PATH=/xx/yy/zz:$LD_LIBRARY_PATH

where /xx/yy/zz represent the path to coinhsl lib.

I was able to get this to work. I will describe my application and the integration test here.

The Example Application

The example application has two classes and one interface that are relevant to this problem:

1. The application context configuration class
2. The entity class
3. The repository interface

These classes and the repository interface are described in the following.

The source code of the PersistenceContext class looks as follows:

import com.jolbox.bonecp.BoneCPDataSource;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.PropertySource;
import org.springframework.core.env.Environment;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.orm.jpa.JpaTransactionManager;
import org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean;
import org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import javax.sql.DataSource;
import java.util.Properties;

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(basePackages = "net.petrikainulainen.spring.datajpa.todo.repository")
@PropertySource("classpath:application.properties")
public class PersistenceContext {

    protected static final String PROPERTY_NAME_DATABASE_DRIVER = "db.driver";
    protected static final String PROPERTY_NAME_DATABASE_PASSWORD = "db.password";
    protected static final String PROPERTY_NAME_DATABASE_URL = "db.url";
    protected static final String PROPERTY_NAME_DATABASE_USERNAME = "db.username";

    private static final String PROPERTY_NAME_HIBERNATE_DIALECT = "hibernate.dialect";
    private static final String PROPERTY_NAME_HIBERNATE_FORMAT_SQL = "hibernate.format_sql";
    private static final String PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO = "hibernate.hbm2ddl.auto";
    private static final String PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY = "hibernate.ejb.naming_strategy";
    private static final String PROPERTY_NAME_HIBERNATE_SHOW_SQL = "hibernate.show_sql";

    private static final String PROPERTY_PACKAGES_TO_SCAN = "net.petrikainulainen.spring.datajpa.todo.model";

    @Autowired
    private Environment environment;

    @Bean
    public DataSource dataSource() {
        BoneCPDataSource dataSource = new BoneCPDataSource();

        dataSource.setDriverClass(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_DRIVER));
        dataSource.setJdbcUrl(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_URL));
        dataSource.setUsername(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_USERNAME));
        dataSource.setPassword(environment.getRequiredProperty(PROPERTY_NAME_DATABASE_PASSWORD));

        return dataSource;
    }

    @Bean
    public JpaTransactionManager transactionManager() {
        JpaTransactionManager transactionManager = new JpaTransactionManager();

        transactionManager.setEntityManagerFactory(entityManagerFactory().getObject());

        return transactionManager;
    }

    @Bean
    public LocalContainerEntityManagerFactoryBean entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean entityManagerFactoryBean = new LocalContainerEntityManagerFactoryBean();

        entityManagerFactoryBean.setDataSource(dataSource());
        entityManagerFactoryBean.setJpaVendorAdapter(new HibernateJpaVendorAdapter());
        entityManagerFactoryBean.setPackagesToScan(PROPERTY_PACKAGES_TO_SCAN);

        Properties jpaProperties = new Properties();
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_DIALECT, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_DIALECT));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_FORMAT_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_FORMAT_SQL));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_HBM2DDL_AUTO));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_NAMING_STRATEGY));
        jpaProperties.put(PROPERTY_NAME_HIBERNATE_SHOW_SQL, environment.getRequiredProperty(PROPERTY_NAME_HIBERNATE_SHOW_SQL));

        entityManagerFactoryBean.setJpaProperties(jpaProperties);

        return entityManagerFactoryBean;
    }
}

Let's assume that we have a simple entity called Todo which source code looks as follows:

@Entity
@Table(name="todos")
public class Todo {

    public static final int MAX_LENGTH_DESCRIPTION = 500;
    public static final int MAX_LENGTH_TITLE = 100;

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @Column(name = "description", nullable = true, length = MAX_LENGTH_DESCRIPTION)
    private String description;

    @Column(name = "title", nullable = false, length = MAX_LENGTH_TITLE)
    private String title;

    @Version
    private long version;
}

Our repository interface has a single method called updateTitle() which updates the title of a todo entry. The source code of the TodoRepository interface looks as follows:

import net.petrikainulainen.spring.datajpa.todo.model.Todo;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.jpa.repository.Modifying;
import org.springframework.data.jpa.repository.Query;
import org.springframework.data.repository.query.Param;

import java.util.List;

public interface TodoRepository extends JpaRepository<Todo, Long> {

    @Modifying
    @Query("Update Todo t SET t.title=:title WHERE t.id=:id")
    public void updateTitle(@Param("id") Long id, @Param("title") String title);
}

The updateTitle() method is not annotated with the @Transactional annotation because I think that it is best to use a service layer as a transaction boundary.

The Integration Test

The Integration Test uses DbUnit, Spring Test and Spring-Test-DBUnit. It has three components which are relevant to this problem:

1. The DbUnit dataset which is used to initialize the database into a known state before the test is executed.
2. The DbUnit dataset which is used to verify that the title of the entity is updated.
3. The integration test.

These components are described with more details in the following.

The name of the DbUnit dataset file which is used to initialize the database to known state is toDoData.xml and its content looks as follows:

<dataset>
    <todos id="1" description="Lorem ipsum" title="Foo" version="0"/>
    <todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>

The name of the DbUnit dataset which is used to verify that the title of the todo entry is updated is called toDoData-update.xml and its content looks as follows (for some reason the version of the todo entry was not updated but the title was. Any ideas why?):

<dataset>
    <todos id="1" description="Lorem ipsum" title="FooBar" version="0"/>
    <todos id="2" description="Lorem ipsum" title="Bar" version="0"/>
</dataset>

The source code of the actual integration test looks as follows (Remember to annotate the test method with the @Transactional annotation):

import com.github.springtestdbunit.DbUnitTestExecutionListener;
import com.github.springtestdbunit.TransactionDbUnitTestExecutionListener;
import com.github.springtestdbunit.annotation.DatabaseSetup;
import com.github.springtestdbunit.annotation.ExpectedDatabase;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.annotation.Rollback;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.TestExecutionListeners;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import org.springframework.test.context.support.DependencyInjectionTestExecutionListener;
import org.springframework.test.context.support.DirtiesContextTestExecutionListener;
import org.springframework.test.context.transaction.TransactionalTestExecutionListener;
import org.springframework.transaction.annotation.Transactional;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = {PersistenceContext.class})
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
        DirtiesContextTestExecutionListener.class,
        TransactionalTestExecutionListener.class,
        DbUnitTestExecutionListener.class })
@DatabaseSetup("todoData.xml")
public class ITTodoRepositoryTest {

    @Autowired
    private TodoRepository repository;

    @Test
    @Transactional
    @ExpectedDatabase("toDoData-update.xml")
    public void updateTitle_ShouldUpdateTitle() {
        repository.updateTitle(1L, "FooBar");
    }
}

After I run the integration test, the test passes and the title of the todo entry is updated. The only problem which I am having is that the version field is not updated. Any ideas why?

I undestand that this description is a bit vague. If you want to get more information about writing integration tests for Spring Data JPA repositories, you can read my blog post about it.

For example, a logout button can be written like this:

<button class="btn btn-primary" onclick="location.href={% url 'logout'%}">Logout</button>

Where logout endpoint:

#urls.py:
url(r'^logout/$', auth_views.logout, {'next_page': '/'}, name='logout'),

Many hours spent to clarify what was that. Please, read this post to get the advanced .HTACCESS codes and learn what they do.

You can use:

Header append Vary "Accept-Encoding"
#or
Header set Vary "Accept-Encoding"

I've prepared my own solution based on all above codes.

      $("textarea.ckeditor")
      .each(function () {

                var editorId = $(this).attr("id");

                try {    
                    var instance = CKEDITOR.instances[editorId];
                    if (instance) { instance.destroy(true); }

                }
                catch(e) {}
                finally {
                    CKEDITOR.replace(editorId);
                }
            });

It works perfectly for me.

Sometimes after AJAX request there is wrong DOM structure. For instace:

<div id="result">
   <div id="result>
   //CONTENT
   </div>
</div>

This will cause issue as well, and ckEditor will not work. So make sure that you have correct DOM structure.

Maybe the "K" format specifier would be of some use. This is the only one that seems to mention the use of capital "Z".

"Z" is kind of a unique case for DateTimes. The literal "Z" is actually part of the ISO 8601 datetime standard for UTC times. When "Z" (Zulu) is tacked on the end of a time, it indicates that that time is UTC, so really the literal Z is part of the time. This probably creates a few problems for the date format library in .NET, since it's actually a literal, rather than a format specifier.

You could simply get the character length of the current directory, and remove them from your absolute list

setlocal EnableDelayedExpansion
for /L %%n in (1 1 500) do if "!__cd__:~%%n,1!" neq "" set /a "len=%%n+1"
setlocal DisableDelayedExpansion
for /r . %%g in (*.log) do (
  set "absPath=%%g"
  setlocal EnableDelayedExpansion
  set "relPath=!absPath:~%len%!"
  echo(!relPath!
  endlocal
)

I would suggest the method presented on the Gradle forum:

def createMinifyCssTask(def brand, def sourceFile, def destFile) {
    return tasks.create("minify${brand}Css", com.eriwen.gradle.css.tasks.MinifyCssTask) {
        source = sourceFile
        dest = destFile
    }
}

I have used this method myself to create custom tasks, and it works very well.

If you want to match a word A in a string and not to match a word B. For example: If you have a text:

1. I have a two pets - dog and a cat
2. I have a pet - dog

If you want to search for lines of text that HAVE a dog for a pet and DOESN'T have cat you can use this regular expression:

^(?=.*?\bdog\b)((?!cat).)*$

It will find only second line:

2. I have a pet - dog

The evaluated value for settext was integer so it went to see a resource attached to it but it was not found, you wanted to set text so it should be string so convert integer into string by attaching .toStringe or String.valueOf(int) will solve your problem!

You need to remove TFS credentials from Windows Vault to clear and force to ask new TFS credentials in Visual Studio

1. Go to Control Panel (Start -> Control Panel).

2. Click User Accounts ( or User Accounts and Family Safety->User Accounts in Windows 7 Machine)

3. Click Credential Manager (or Manage your credentials)

4. In Credential Manager page, you can see the two type of credentials

      i. Windows Credentials
      ii. Generic Credentials
   

5.Click on two credentials modify link, click the link Remove from vault to remove stored TFS credentials.

Now, When you login into Visual Studio you will be asked to give credentials to connect TFS.

Note: Don't forgot to uncheck the option Remember my credentials to force to ask credentials for every TFS connections.

I have also received this error when developing automatic tests for components. In this context the following import should be done:

import { RouterTestingModule } from "@angular/router/testing";

const testBedConfiguration = {
  imports: [SharedModule,
    BrowserAnimationsModule,
    RouterTestingModule.withRoutes([]),
  ],

Use a parameterized query to prevent Sql injections (secutity problem)

Use the using statement so the connection will be closed and resources will be disposed.

using(var connection = new SqlConnection("connectionString"))
{
    connection.Open();
    var sql = "INSERT INTO Main(FirstName, SecondName) VALUES(@FirstName, @SecondName)";
    using(var cmd = new SqlCommand(sql, connection))
    {
        cmd.Parameters.AddWithValue("@FirstName", txFirstName.Text);
        cmd.Parameters.AddWithValue("@SecondName", txSecondName.Text);

        cmd.ExecuteNonQuery();
    }
}

I'm not sure that I understand what you mean by "rights of ownership".

If User B owns a stored procedure, User B can grant User A permission to run the stored procedure

GRANT EXECUTE ON b.procedure_name TO a

User A would then call the procedure using the fully qualified name, i.e.

BEGIN
  b.procedure_name( <<list of parameters>> );
END;

Alternately, User A can create a synonym in order to avoid having to use the fully qualified procedure name.

CREATE SYNONYM procedure_name FOR b.procedure_name;

BEGIN
  procedure_name( <<list of parameters>> );
END;

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

import io
from contextlib import redirect_stdout

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

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

i'am working with hibernate 5 and postgres, and this worked form me.

@Column(name = "ACCOUNT_TYPE", ***nullable***=false, columnDefinition="varchar2 default 'END_USER'")

Try putting your code inside a main function in testMain.py

import parallelTestModule

if __name__ ==  '__main__':
  extractor = parallelTestModule.ParallelExtractor()
  extractor.runInParallel(numProcesses=2, numThreads=4)

See the docs:

"For an explanation of why (on Windows) the if __name__ == '__main__' 
part is necessary, see Programming guidelines."

which say

"Make sure that the main module can be safely imported by a new Python interpreter without causing unintended side effects (such a starting a new process)."

... by using if __name__ == '__main__'

It works!

ECU = EC2 Compute Unit. More from here: http://aws.amazon.com/ec2/faqs/#What_is_an_EC2_Compute_Unit_and_why_did_you_introduce_it

Amazon EC2 uses a variety of measures to provide each instance with a consistent and predictable amount of CPU capacity. In order to make it easy for developers to compare CPU capacity between different instance types, we have defined an Amazon EC2 Compute Unit. The amount of CPU that is allocated to a particular instance is expressed in terms of these EC2 Compute Units. We use several benchmarks and tests to manage the consistency and predictability of the performance from an EC2 Compute Unit. One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor. This is also the equivalent to an early-2006 1.7 GHz Xeon processor referenced in our original documentation. Over time, we may add or substitute measures that go into the definition of an EC2 Compute Unit, if we find metrics that will give you a clearer picture of compute capacity.

    while(size--){
        if(IN & L) OUT = OUT | R; // start from MSB  1000.xxxx
        if(IN & R) OUT = OUT | L; // start from LSB  xxxx.0001
        L = L >> 1;
        R = R << 1;

    return OUT;

How about this?

import fileinput
import sys

counter=0
for line in fileinput.input([sys.argv[1]]):
    counter+=1

fileinput.close()
print counter

Moreover, you can use (x = Eval("item") ?? 0) in this case.

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

• https://github.com/powermock/powermock/wiki/Mockito (PowerMock Overview / Examples)
• http://site.mockito.org/mockito/docs/current/org/mockito/Mockito.html (Mockito Overview / Examples)

solution is easy:

replace

 mask = (50  < df['heart rate'] < 101 &
            140 < df['systolic blood pressure'] < 160 &
            90  < df['dyastolic blood pressure'] < 100 &
            35  < df['temperature'] < 39 &
            11  < df['respiratory rate'] < 19 &
            95  < df['pulse oximetry'] < 100
            , "excellent", "critical")

by

mask = ((50  < df['heart rate'] < 101) &
        (140 < df['systolic blood pressure'] < 160) &
        (90  < df['dyastolic blood pressure'] < 100) &
        (35  < df['temperature'] < 39) &
        (11  < df['respiratory rate'] < 19) &
        (95  < df['pulse oximetry'] < 100)
        , "excellent", "critical")

The best thing to do is to create a "print-only" version of the page.

Oh, wait... this isn't 1999 anymore. Use a print CSS with "display: none".

If you are in a SharePoint Page just use:

_spPageContextInfo.userId;

In SQL Server 2016 Management Studio, the process for getting an azure database to your local machine has been streamlined.

Right click on the database you want to import, click Tasks > Export data-tier application, and export your database to a local .dacpac file.

In your local target SQL server instance, you can right click Databases > Import data-tier application, and once it's local, you can do things like backup and restore the database.

OK, getting the full URL of the current page is easy using pure JavaScript. For example, try this code on this page:

window.location.href;
// use it in the console of this page will return
// http://stackoverflow.com/questions/1034621/get-current-url-in-web-browser"

The window.location.href property returns the URL of the current page.

document.getElementById("root").innerHTML = "The full URL of this page is:<br>" + window.location.href;

<!DOCTYPE html>_x000D_
<html>_x000D_
_x000D_
<body>_x000D_
  <h2>JavaScript</h2>_x000D_
  <h3>The window.location.href</h3>_x000D_

Just not bad to mention these as well:

• if you need a relative path, simply use window.location.pathname;

• if you'd like to get the host name, you can use window.location.hostname;

• and if you need to get the protocol separately, use window.location.protocol

  • also, if your page has hash tag, you can get it like: window.location.hash.

So window.location.href handles all in once... basically:

window.location.protocol + '//' + window.location.hostname + window.location.pathname + window.location.hash === window.location.href;
    //true

Also using window is not needed if already in window scope...

So, in that case, you can use:

location.protocol

location.hostname

location.pathname

location.hash

location.href

If you find it hard to navigate console output of gradle dependencies, you can add the Project reports plugin:

apply plugin: 'project-report'

And generate a HTML report using:

$ ./gradlew htmlDependencyReport

Report can normally be found in build/reports/project/dependencies/index.html

It looks like this:

1) Uninstalling Entity Framework from All projects

2) Restart Visual Studio

3) Reinstalling to all required projects

and it started working

In methods chain form:

db.Serials.GroupBy(i => i.Serial_Number).Select(g => new
    {
        Serial_Number = g.Key,
        uid = g.Max(row => row.uid)
    });

i think you use this method to compress the bitmap

BitmapFactory.Option imageOpts = new BitmapFactory.Options ();
imageOpts.inSampleSize = 2;   // for 1/2 the image to be loaded
Bitmap thumb = Bitmap.createScaledBitmap (BitmapFactory.decodeFile(photoPath, imageOpts), 96, 96, false);

var is essential for anonymous types (as pointed out in one of the previous responses to this question).

I would categorise all other discussion of its pros and cons as "religious war". By that I mean that a comparison and discussion of the relative merits of...

var i = 5;
int j = 5;

SomeType someType = new SomeType();
var someType = new SomeType();

...is entirely subjective.

Implicit typing means that there is no runtime penalty for any variable being declared using the var keyword, so it comes down to being a debate about what makes the developers happy.

I think the query you want is this:

SELECT BrandId, SUM(ICount),
       SUM(sum(ICount)) over () as TotalCount,
       100.0 * SUM(ICount) / SUM(sum(Icount)) over () as Percentage
FROM Table 
WHERE DateId  = 20130618
group by BrandId;

This does the group by for brand. And it calculates the "Percentage". This version should produce a number between 0 and 100.

A simple string.Concat() is what you need.

string[] test = new string[2];

test[0] = "Hello ";
test[1] = "World!";

string result = string.Concat(test);

If you also need to add a seperator (space, comma etc) then, string.Join() should be used.

string[] test = new string[2];

test[0] = "Red";
test[1] = "Blue";

string result = string.Join(",", test);

If you have to perform this on a string array with hundereds of elements than string.Join() is better by performace point of view. Just give a "" (blank) argument as seperator. StringBuilder can also be used for sake of performance, but it will make code a bit longer.

Your best bet may be to create a function that sets styles on your own:

var setStyle = function(p_elem, p_styles)
{
    var s;
    for (s in p_styles)
    {
        p_elem.style[s] = p_styles[s];
    }
}

setStyle(myDiv, {'color': '#F00', 'backgroundColor': '#000'});
setStyle(myDiv, {'color': mycolorvar, 'backgroundColor': mybgvar});

Note that you will still have to use the javascript-compatible property names (hence backgroundColor)

I had the same problem, and none of the above solutions worked. Actually, the file include/boost/version.hpp could not be read (by the cmake script launched by jenkins).

I had to manually change the permission of the (boost) library (even though jenkins belongs to the group, but that is another problem linked to jenkins that I could not figure out):

chmod o+wx ${BOOST_ROOT} -R # allow reading/execution on the whole library
#chmod g+wx ${BOOST_ROOT} -R # this did not suffice, strangely, but it is another story I guess

Step 1: Run the application using following parameters.

-Dcom.sun.management.jmxremote.port=9999 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false

Above arguments bind the application to the port 9999.

Step 2: Launch jconsole by executing the command jconsole in command prompt or terminal.

Select ‘Remote Process:’ and enter the url as {IP_Address}:9999 and click on Connect button to connect to the remote application.

You can refer this link for complete application.

Don't know much VB.NET syntax but here's and idea

Dim source As New Bitmap("C:\image.png") 
Dim target As New Bitmap(size.Width, size.Height, PixelFormat.Format24bppRgb)

Using graphics As Graphics = Graphics.FromImage(target)
    graphics.DrawImage(source, new Size(48, 48)) 
End Using

You can use the option -C (or --directory if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar. The directory should exist:

mkdir foo
tar -xzf bar.tar.gz -C foo

If you are not using a tar capable of extracting to a specific directory, you can simply cd into your target directory prior to calling tar; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:

mkdir foo
(cd foo; tar -xzf ../bar.tar.gz)  # instead of ../ you can use an absolute path as well

Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:

TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz

Edit .gitconfig file in c:\Users\YourUser folder and add:

[core]
editor = 'C:\\Program files\\path\\to\\editor.exe'

If you just want the button to have different styling while the mouse is pressed you can use the :active pseudo class.

.button:active {
}

If on the other hand you want the style to stay after clicking you will have to use javascript.

The response provided by Ranveer (second answer above) absolutely does NOT work.

He says to use col-xx-offset-#, but that is not how offsets are used.

If you wasted your time trying to use col-xx-offset-#, as I did based on his answer, the solution is to use offset-xx-#.

You can use https://appery.io/ It is the same phonegap but in very convinient wrapper

Put this code on a file on your project, something likes Utils.swift:

extension String
{   
    func trim() -> String
    {
        return self.stringByTrimmingCharactersInSet(NSCharacterSet.whitespaceCharacterSet())
    }
}

So you will be able to do this:

let result = " abc ".trim()
// result == "abc"

Swift 3.0 Solution

extension String
{   
    func trim() -> String
   {
    return self.trimmingCharacters(in: NSCharacterSet.whitespaces)
   }
}

So you will be able to do this:

let result = " Hello World ".trim()
// result = "HelloWorld"

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

JSON:-

For POST request using json object it can be configured by selecting

After update to macOS 10.13.3

After updating do macOS 10.13, I had to install "Command Line Tools (macOS 10.13) for Xcode 9.3" downloaded from https://developer.apple.com/download/more/

require(ggplot2)
require(nlme)

set.seed(101)
mp <-data.frame(year=1990:2010)
N <- nrow(mp)

mp <- within(mp,
         {
             wav <- rnorm(N)*cos(2*pi*year)+rnorm(N)*sin(2*pi*year)+5
             wow <- rnorm(N)*wav+rnorm(N)*wav^3
         })

m01 <- gls(wow~poly(wav,3), data=mp, correlation = corARMA(p=1))

Get fitted values (the same as m01$fitted)

fit <- predict(m01)

Normally we could use something like predict(...,se.fit=TRUE) to get the confidence intervals on the prediction, but gls doesn't provide this capability. We use a recipe similar to the one shown at http://glmm.wikidot.com/faq :

V <- vcov(m01)
X <- model.matrix(~poly(wav,3),data=mp)
se.fit <- sqrt(diag(X %*% V %*% t(X)))

Put together a "prediction frame":

predframe <- with(mp,data.frame(year,wav,
                                wow=fit,lwr=fit-1.96*se.fit,upr=fit+1.96*se.fit))

Now plot with geom_ribbon

(p1 <- ggplot(mp, aes(year, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It's easier to see that we got the right answer if we plot against wav rather than year:

(p2 <- ggplot(mp, aes(wav, wow))+
    geom_point()+
    geom_line(data=predframe)+
    geom_ribbon(data=predframe,aes(ymin=lwr,ymax=upr),alpha=0.3))

It would be nice to do the predictions with more resolution, but it's a little tricky to do this with the results of poly() fits -- see ?makepredictcall.

In Mac:

Kill process Terminal: kill <pid>

Find pid: Terminal: lsof -i:<port>

From Diego Pino answer

you can't use VALUES clause when inserting data using another SELECT query. see INSERT SYNTAX

INSERT INTO user
(
 id, name, username, email, opted_in
)
(
    SELECT id, name, username, email, opted_in
    FROM user
         LEFT JOIN user_permission AS userPerm
            ON user.id = userPerm.user_id
);

Speed

Lookups in lists are O(n), lookups in dictionaries are amortized O(1), with regard to the number of items in the data structure. If you don't need to associate values, use sets.

Memory

Both dictionaries and sets use hashing and they use much more memory than only for object storage. According to A.M. Kuchling in Beautiful Code, the implementation tries to keep the hash 2/3 full, so you might waste quite some memory.

If you do not add new entries on the fly (which you do, based on your updated question), it might be worthwhile to sort the list and use binary search. This is O(log n), and is likely to be slower for strings, impossible for objects which do not have a natural ordering.

Using suggestions from answers on this page and this other one (ANT_HOME is set incorrectly or ant could not be located), the ultimate fix was the following:

1. Adding a ANT_HOME environment variable that points to the ROOT directory of your Apache ant directory location. (Not the bin sub-dir!)

2. Adding a JAVA_HOME environment variable that points to the ROOT directory of your Java JDK (or SDK) directory location. (NOT your JRE and not the bin sub-dir!)

3. Appended %ANT_HOME%\bin;%JAVA_HOME%\bin to the PATH environment variable.

4. Make sure you close any command window(s) that were open prior to the changes above. Only command windows opened after the changes will have the updated environment variables.

Selected answer throws exceptions, and the answer from Carlos Toledo applies filtering after retrieving all values from the database.

The following one runs a single round-trip and reads a single value, using any possible indexes, without an exception.

Steps to find the UDID from IPhone and IPad Without Using itunes

1. Open below link in your iPhone or iPad : - http://get.udid.io/

2. Click on the Button Green color - Tap to find UDID

3. Get your UDID will Appear, Click on the right side top INSTALL button

4 . UDID will appear Copy the UDID.

Short and elegant

#include <vector>
#include <string>
using namespace std;

vector<string> split(string data, string token)
{
    vector<string> output;
    size_t pos = string::npos; // size_t to avoid improbable overflow
    do
    {
        pos = data.find(token);
        output.push_back(data.substr(0, pos));
        if (string::npos != pos)
            data = data.substr(pos + token.size());
    } while (string::npos != pos);
    return output;
}

can use any string as delimiter, also can be used with binary data (std::string supports binary data, including nulls)

using:

auto a = split("this!!is!!!example!string", "!!");

output:

this
is
!example!string

Prefix the variable name with env:

$env:path

For example, if you want to print the value of environment value "MINISHIFT_USERNAME", then command will be:

$env:MINISHIFT_USERNAME

You can also enumerate all variables via the env drive:

Get-ChildItem env:

after some experimenting, this worked best for me:

.tooltip-inner {
    max-width: 350px; /* set this to your maximum fitting width */
    width: inherit; /* will take up least amount of space */ 
}

Can be pretty easily done assuming you're using jQuery and css3:

http://jsfiddle.net/S7JDU/8/

HTML:

<div id="clicker">Click Here</div>
<div id="rotating"></div>

CSS:

#clicker { 
    width: 100px; 
    height: 100px; 
    background-color: Green; 
}

#rotating { 
    width: 100px; 
    height: 100px; 
    background-color: Red; 
    margin-top: 50px; 
    -webkit-transition: all 0.3s ease-in-out;
    -moz-transition: all 0.3s ease-in-out;
    -o-transition: all 0.3s ease-in-out;
    transition: all 0.3s ease-in-out;
}

.rotated { 
    transform:rotate(25deg); 
    -webkit-transform:rotate(25deg); 
    -moz-transform:rotate(25deg); 
    -o-transform:rotate(25deg); 
}

JS:

$(document).ready(function() {
    $('#clicker').click(function() {
        $('#rotating').toggleClass('rotated');
    });
});

If you add the favicon into the root/images folder with the name favicon.ico browser will automatically understand and get it as favicon.I tested and worked. your link must be www.website.com/images/favicon.ico

For more information look this answer:

Do you have to include <link rel="icon" href="favicon.ico" type="image/x-icon" />?

I know it is late but I just want to share on what I have done for this. I'm not allowed to add another table or trigger so I need to generate it in a single query upon insert. For your case, can you try this query.

CREATE TABLE YOURTABLE(
IDNUMBER VARCHAR(7) NOT NULL PRIMARY KEY,
ENAME VARCHAR(30) not null
);

Perform a select and use this select query and save to the parameter @IDNUMBER

(SELECT IFNULL
     (CONCAT('LHPL',LPAD(
       (SUBSTRING_INDEX
        (MAX(`IDNUMBER`), 'LHPL',-1) + 1), 5, '0')), 'LHPL001')
    AS 'IDNUMBER' FROM YOURTABLE ORDER BY `IDNUMBER` ASC)

And then Insert query will be :

INSERT INTO YOURTABLE(IDNUMBER, ENAME) VALUES 
(@IDNUMBER, 'EMPLOYEE NAME');

The result will be the same as the other answer but the difference is, you will not need to create another table or trigger. I hope that I can help someone that have a same case as mine.

Prototypes can be a hassle to work with, and from the _PROTO part of the error it appears your error is caused by, say, HTMLCanvasElement.prototype.width, possibly as an attempt to resize all the canvases at once.

As a suggestion, if you are trying to resize a number of canvases at once, you could try:

<canvas></canvas>
<canvas></canvas>
<canvas></canvas>
<script type="text/javascript">
    ...
</script>

In the JavaScript, instead of invoking a prototype, try this:

$$ = function(){
    return document.querySelectorAll.apply(document,arguments);
}
for(var i in $$('canvas')){
    canvas = $$('canvas')[i];
    canvas.width = canvas.width+100;
    canvas.height = canvas.height+100;
}

This would resize all the canvases by adding 100 px to their size, as is demonstrated in this example

The two answers before mine are correct - you can use OnItemClickListener.

It's good to note that the difference between OnItemClickListener and OnItemSelectedListener, while sounding subtle, is in fact significant, as item selection and focus are related with the touch mode of your AdapterView.

By default, in touch mode, there is no selection and focus. You can take a look here for further info on the subject.

firstly I don't think there is just one solution to your problem....

As you know each browser is vastly differant.

But lets see if we can get any closer to the answer you need....

I think IE Might be easy...

Check this link http://support.microsoft.com/kb/181050

For Firefox try this:

Open Firefox, and in the address bar, type "about:config" (without quotes). From there, scroll down to the Network.http.keep-alive and make sure that is set to "true". If it is not, double click it, and it will go from false to true. Now, go one below that to network.http.keep-alive.timeout -- and change that number by double clicking it. if you put in, say, 500 there, you should be good. let us know if this helps at all

I have some experiences in Wamp 3.0 and Apache 2.4 .

After all works do this steps:

1- Disable nod32.

2- Add this line to <VirtualHost *:80> block in httpd-vhosts.conf file:

Require ip 192.168.100 #client ip, allow 192.168.100.### ip's access

DateTime dt = DateTime.ParseExact("11-22-2012 12:00 am", "MM-dd-yyyy hh:mm tt", System.Globalization.CultureInfo.InvariantCulture);

The safest "correct" method would be:

1. Parse the url into an array with parse_url()
2. Extract the query portion, decompose that into an array using parse_str()
3. Delete the query parameters you want by unset() them from the array
4. Rebuild the original url using http_build_query()

Quick and dirty is to use a string search/replace and/or regex to kill off the value.

Well, you can just put multiple "where" clauses in directly, but I don't think you want to. Multiple "where" clauses ends up with a more restrictive filter - I think you want a less restrictive one. I think you really want:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where r.Field<string>("UserName") != "XXXX" &&
                  r.Field<string>("UserName") != "YYYY"
            select r;

DataTable newDT = query.CopyToDataTable();

Note the && instead of ||. You want to select the row if the username isn't XXXX and the username isn't YYYY.

EDIT: If you have a whole collection, it's even easier. Suppose the collection is called ignoredUserNames:

DataTable tempData = (DataTable)grdUsageRecords.DataSource;
var query = from r in tempData.AsEnumerable()
            where !ignoredUserNames.Contains(r.Field<string>("UserName"))
            select r;

DataTable newDT = query.CopyToDataTable();

Ideally you'd want to make this a HashSet<string> to avoid the Contains call taking a long time, but if the collection is small enough it won't make much odds.

This worked for me:

Add this in index.html (inside src folder along with favicon.ico)

**<link rel="icon" href="/src/favicon.ico" type="image/x-icon" />**

webpack.config.js is like:

 plugins: [new HtmlWebpackPlugin({`enter code here`
        template: './src/index.html'
    })],

If you're an Azure DevOps user looking for both where and how to exclude files and folders, here ya go:

1. Edit your pipeline
2. Make sure you have the "Prepare analysis on SonarQube" task added. You'll need to look elsewhere if you need help configuring this. Suggestion: Use the UI pipeline editor vs the yaml editor if you are missing the manage link. At present, there is no way to convert to UI from yaml. Just recreate the pipeline. If using git, you can delete the yaml from the root of your repo.
3. Under the 'Advanced' section of the "Prepare analysis on SonarQube" task, you can add exclusions. See advice given by others for specific exclusion formats.

Example:

# Additional properties that will be passed to the scanner, 
# Put one key=value per line, example:
# sonar.exclusions=**/*.bin
sonar.exclusions=MyProjectName/MyWebContentFolder/**

Note: If you're not sure on the path, you can go into sonarqube, view your project, look at all or new 'Code Smells' and the path you need is listed above each grouping of issues. You can grab the full path to a file or use wilds like these examples:

• MyProjectName/MyCodeFile.cs
• MyProjectName/**

If you don't have the 'Run Code Analysis' task added, do that and place it somewhere after the 'Build solution **/*.sln' task.

Save and Queue and then check out your sonarqube server to see if the exclusions worked.

This is a little longer, but more versatile for cases where there are multiple, randomly placed, numbers in the string. Also, it requires no imports.

def getNumbers( input ):
    # Collect Info
    compile = ""
    complete = []

    for letter in input:
        # If compiled string
        if compile:
            # If compiled and letter are same type, append letter
            if compile.isdigit() == letter.isdigit():
                compile += letter
            
            # If compiled and letter are different types, append compiled string, and begin with letter
            else:
                complete.append( compile )
                compile = letter
            
        # If no compiled string, begin with letter
        else:
            compile = letter
        
    # Append leftover compiled string
    if compile:
        complete.append( compile )
    
    # Return numbers only
    numbers = [ word for word in complete if word.isdigit() ]
        
    return numbers

[k for k,v in l if v =='delicia']

here l is the list of tuples-[(1,"juca"),(22,"james"),(53,"xuxa"),(44,"delicia")]

And instead of converting it to a dict, we are using llist comprehension.

*Key* in Key,Value in list, where value = **delicia**

Add InitialValue="0" in Required field validator tag

 <asp:RequiredFieldValidator InitialValue="-1" ID="Req_ID"
      Display="Dynamic" ValidationGroup="g1" runat="server"
      ControlToValidate="ControlID"
      InitialValue="0" ErrorMessage="ErrorMessage">
 </asp:RequiredFieldValidator>

Your [hidden] will work but you need to check the css:

<input class="txt" type="password" [(ngModel)]="input_pw" [hidden]="isHidden" />

And the css:

[hidden] {
  display: none !important;
}

That should work as you want.

You simply misspelled $stateParam, it should be $stateParams (with an s). That's why you get undefined ;)

Other way is using of built-in method start timer & event TimerEvent.

Header:

#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
    Q_OBJECT

public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();

private:
    Ui::MainWindow *ui;
    int timerId;

protected:
    void timerEvent(QTimerEvent *event);
};

#endif // MAINWINDOW_H

Source:

#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QDebug>

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);

    timerId = startTimer(1000);
}

MainWindow::~MainWindow()
{
    killTimer(timerId);
    delete ui;
}

void MainWindow::timerEvent(QTimerEvent *event)
{
    qDebug() << "Update...";
}

Got this example from cppreference. It works with:

GCC 10.1+ with flag -std=c++20

#include <ranges>
#include <iostream>
 
int main()
{
    static constexpr auto il = {3, 1, 4, 1, 5, 9};
 
    std::ranges::reverse_view rv {il};
    for (int i : rv)
        std::cout << i << ' ';
 
    std::cout << '\n';
 
    for(int i : il | std::views::reverse)
        std::cout << i << ' ';
}

  let m2 = Math.abs(m % 60);_x000D_
  m2 = (m2 < 10) ? '0' + m2 : m2;_x000D_
  return (h < 0 ? '' : '+') + h + ':' + m2;_x000D_

_x000D_
console.log(minToHm(210)) // "+3:30"_x000D_
console.log(minToHm(-210)) // "-3:30"_x000D_
console.log(minToHm(0)) // "+0:00"

minToHm(210)
"+3:30"

minToHm(-210)
"-3:30"

This can be done simpler by adding two links, one with text and href and one with the dropdown and caret:

<a href="{{route('posts.index')}}">Posts</a>
<a href="{{route('posts.index')}}" class="dropdown-toggle" data-toggle="dropdown" role="link" aria-haspopup="true" aria- expanded="false"></a>
<ul class="dropdown-menu navbar-inverse bg-inverse">
    <li><a href="{{route('posts.create')}}">Create</a></li>
</ul>

Now you click the caret for dropdown and the link as a link. No css or js needed. I use Bootstrap 4 4.0.0-alpha.6, defining the caret is not necessary, it appears without the html.

With the introduction of std::optional in C++17 you can pass optional arguments:

#include <iostream>
#include <string>
#include <optional>

void myfunc(const std::string& id, const std::optional<std::string>& param = std::nullopt)
{
    std::cout << "id=" << id << ", param=";

    if (param)
        std::cout << *param << std::endl;
    else
        std::cout << "<parameter not set>" << std::endl;
}

int main() 
{
    myfunc("first");
    myfunc("second" , "something");
}

Output:

id=first param=<parameter not set>
id=second param=something

See https://en.cppreference.com/w/cpp/utility/optional

Using Newton C++

bool exists_linear( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

bool exists_binary( INPUT_ITERATOR first, INPUT_ITERATOR last, const T& value )

the code will be something like this:

if ( newton::exists_linear(arr.begin(), arr.end(), value) )
   std::cout << "found" << std::endl;
else
   std::cout << "not found" << std::endl;

both exists_linear and exists_binary use std implementations. binary use std::binary_search, and linear use std::find, but return directly a bool, not an iterator.

Change the less-than operator to a greater-than-or-equal-to operator:

From this post:

To get the entire PC CPU and Memory usage:

using System.Diagnostics;

Then declare globally:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Processor", "% Processor Time", "_Total"); 

Then to get the CPU time, simply call the NextValue() method:

this.theCPUCounter.NextValue();

This will get you the CPU usage

As for memory usage, same thing applies I believe:

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Memory", "Available MBytes");

Then to get the memory usage, simply call the NextValue() method:

this.theMemCounter.NextValue();

For a specific process CPU and Memory usage:

private PerformanceCounter theCPUCounter = 
   new PerformanceCounter("Process", "% Processor Time",              
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

private PerformanceCounter theMemCounter = 
   new PerformanceCounter("Process", "Working Set",
   Process.GetCurrentProcess().ProcessName);

where Process.GetCurrentProcess().ProcessName is the process name you wish to get the information about.

Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?

To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters

The difference between Processor\% Processor Time and Process\% Processor Time is Processor is from the PC itself and Process is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters

An alternative to using the Performance Counter

Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

Note that Color.GetSaturation() and Color.GetBrightness() return HSL values, not HSV.
The following code demonstrates the difference.

Color original = Color.FromArgb(50, 120, 200);
// original = {Name=ff3278c8, ARGB=(255, 50, 120, 200)}

double hue;
double saturation;
double value;
ColorToHSV(original, out hue, out saturation, out value);
// hue        = 212.0
// saturation = 0.75
// value      = 0.78431372549019607

Color copy = ColorFromHSV(hue, saturation, value);
// copy = {Name=ff3278c8, ARGB=(255, 50, 120, 200)}

// Compare that to the HSL values that the .NET framework provides: 
original.GetHue();        // 212.0
original.GetSaturation(); // 0.6
original.GetBrightness(); // 0.490196079

The following C# code is what you want. It converts between RGB and HSV using the algorithms described on Wikipedia. The ranges are 0 - 360 for hue, and 0 - 1 for saturation or value.

public static void ColorToHSV(Color color, out double hue, out double saturation, out double value)
{
    int max = Math.Max(color.R, Math.Max(color.G, color.B));
    int min = Math.Min(color.R, Math.Min(color.G, color.B));

    hue = color.GetHue();
    saturation = (max == 0) ? 0 : 1d - (1d * min / max);
    value = max / 255d;
}

public static Color ColorFromHSV(double hue, double saturation, double value)
{
    int hi = Convert.ToInt32(Math.Floor(hue / 60)) % 6;
    double f = hue / 60 - Math.Floor(hue / 60);

    value = value * 255;
    int v = Convert.ToInt32(value);
    int p = Convert.ToInt32(value * (1 - saturation));
    int q = Convert.ToInt32(value * (1 - f * saturation));
    int t = Convert.ToInt32(value * (1 - (1 - f) * saturation));

    if (hi == 0)
        return Color.FromArgb(255, v, t, p);
    else if (hi == 1)
        return Color.FromArgb(255, q, v, p);
    else if (hi == 2)
        return Color.FromArgb(255, p, v, t);
    else if (hi == 3)
        return Color.FromArgb(255, p, q, v);
    else if (hi == 4)
        return Color.FromArgb(255, t, p, v);
    else
        return Color.FromArgb(255, v, p, q);
}

Yes, querySelectorAll does take a group of selectors:

form, p, legend

When I wanted to change namespace and the solution name I did as follows:
1) changed the namespace by selecting it and renaming it and I did the same with solution name
2) clicked on the light bulb and renamed all the instances of old namespace
3) removed all the projects from the solution
4) closed the visual studio
5) renamed all the projects in windows explorer
6) opened visual studio and added all the projects again
7) rename namespaces in all projects in their properties
8) removed bin folder (from all projects)
9) build the project again

That worked for me without any problems and my project had as well source control. All was fine after pushing those changes to the remote.

To count the number of a specific filetype in a folder. The example is to count mp3 files on F: drive.

The built-in round() works just fine in Python 2.7 or later.

In response to the OP, there are two problems with your code: you need to set jsonp='callback', and adding in a callback function in a variable like you did does not seem to work.

Update: when I wrote this the Twitter API was just open, but they changed it and it now requires authentication. I changed the second example to a working (2014Q1) example, but now using github.

This does not work any more - as an exercise, see if you can replace it with the Github API:

$('document').ready(function() {
    var pm_url = 'http://twitter.com/status';
    pm_url += '/user_timeline/stephenfry.json';
    pm_url += '?count=10&callback=photos';
    $.ajax({
        url: pm_url,
        dataType: 'jsonp',
        jsonpCallback: 'photos',
        jsonp: 'callback',
    });
});
function photos (data) {
    alert(data);
    console.log(data);
};

although alert()ing an array like that does not really work well... The "Net" tab in Firebug will show you the JSON properly. Another handy trick is doing

alert(JSON.stringify(data));

You can also use the jQuery.getJSON method. Here's a complete html example that gets a list of "gists" from github. This way it creates a randomly named callback function for you, that's the final "callback=?" in the url.

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>JQuery (cross-domain) JSONP Twitter example</title>
        <script type="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
        <script>
            $(document).ready(function(){
                $.getJSON('https://api.github.com/gists?callback=?', function(response){
                    $.each(response.data, function(i, gist){
                        $('#gists').append('<li>' + gist.user.login + " (<a href='" + gist.html_url + "'>" + 
                            (gist.description == "" ? "undescribed" : gist.description) + '</a>)</li>');
                    });
                });
            });
        </script>
    </head>
    <body>
        <ul id="gists"></ul>
    </body>
</html>

"Unexpected end of file" implies that the remote server accepted and closed the connection without sending a response. It's possible that the remote system is too busy to handle the request, or that there's a network bug that randomly drops connections.

It's also possible there is a bug in the server: something in the request causes an internal error, and the server simply closes the connection instead of sending a HTTP error response like it should. Several people suggest this is caused by missing headers or invalid header values in the request.

With the information available it's impossible to say what's going wrong. If you have access to the servers in question you can use packet sniffing tools to find what exactly is sent and received, and look at logs to of the server process to see if there are any error messages.

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

I got the error Can't open file for reading. Inappropriate ioctl for device recently when I migrated an old UB2K forum with a DBM file-based database to a new host. Apparently there are multiple, incompatible implementations of DBM. I had a backup of the database, so I was able to load that, but it seems there are other options e.g. moving a perl script/dbm to a new server, and shifting out of dbm?.

You should specify

<input type="checkbox" name="Days[]" value="Daily">Daily<br>

as array.

Add [] to all names Days and work at php with this like an array.

After it, you can INSERT values at different columns at db, or use implode and save values into one column.

Didn't tested it, but you can try like this. Don't forget to replace mysql with mysqli.

<html>
<body>
<form method="post" action="chk123.php">
Flights on: <br/>
<input type="checkbox" name="Days[]" value="Daily">Daily<br>
<input type="checkbox" name="Days[]" value="Sunday">Sunday<br>
<input type="checkbox" name="Days[]" value="Monday">Monday<br>
<input type="checkbox" name="Days[]" value="Tuesday">Tuesday <br>
<input type="checkbox" name="Days[]" value="Wednesday">Wednesday<br>
<input type="checkbox" name="Days[]" value="Thursday">Thursday <br>
<input type="checkbox" name="Days[]" value="Friday">Friday<br>
<input type="checkbox" name="Days[]" value="Saturday">Saturday <br>
<input type="submit" name="submit" value="submit">
</form>
</body>
</html>

<?php

// Make a MySQL Connection
mysql_connect("localhost", "root", "") or die(mysql_error());
mysql_select_db("test") or die(mysql_error());

$checkBox = implode(',', $_POST['Days']);

if(isset($_POST['submit']))
{       
    $query="INSERT INTO example (orange) VALUES ('" . $checkBox . "')";     

    mysql_query($query) or die (mysql_error() );

    echo "Complete";

}

?>

Simply add this event to your text field. It will prevent a submission on pressing Enter, and you're free to add a submit button or call form.submit() as required:

onKeyPress="if (event.which == 13) return false;"

For example:

<input id="txt" type="text" onKeyPress="if (event.which == 13) return false;"></input>

I would put the secondSet in a HashMap before the comparison. This way you will reduce the second list's search time to n(1). Like this:

HashMap<Integer,Record> hm = new HashMap<Integer,Record>(secondSet.size());
int i = 0;
for(Record secondRecord : secondSet){
    hm.put(i,secondRecord);
    i++;
}
for(Record firstRecord : firstSet){
    for(int i=0; i<secondSet.size(); i++){
    //use hm for comparison
    }
}

I have found two errors during the installing of Magento to localhost.
There are PHP Extension xsl and intl and I have solved the issue by following steps.

1. Open php.ini
2. Remove '#' cha from the lines extension=php_xsl.dll and extension=php_intl.dll.
3. Save the file and restart xamp again
4. Click Try Again on Magento installation page.

Then all the things were passed as well as following picture.

The disabled attribute is not global and is only allowed on form controls. What you could do is set a custom data attribute (perhaps data-disabled) and check for that attribute when you handle the click event.

if you call pyplot as plt

frameon=False is to remove the border around the legend

and '' is passing the information that no variable should be in the legend

import matplotlib.pyplot as plt
plt.legend('',frameon=False)

Well, I've been using temporary tables instead of array variables. Not the greatest solution, but it works.

Note that you don't need to formally define their fields, just create them using a SELECT:

DROP TEMPORARY TABLE IF EXISTS my_temp_table;
CREATE TEMPORARY TABLE my_temp_table
    SELECT first_name FROM people WHERE last_name = 'Smith';

(See also Create temporary table from select statement without using Create Table.)

Also using query builder

DB::table("rates")->get()->sum("rate_value")

To get summation of all rate value inside table rates.

To get summation of user products.

DB::table("users")->get()->sum("products")

Use split()

let mut split = "some string 123 ffd".split("123");

This gives an iterator, which you can loop over, or collect() into a vector.

for s in split {
    println!("{}", s)
}
let vec = split.collect::<Vec<&str>>();
// OR
let vec: Vec<&str> = split.collect();

You remove the original image here:

newImg.animate(css, SPEED, function() {
    img.remove();
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And all that's left behind is newImg. Then you reset link references the image using #rocket:

$("#rocket").attr('src', ...

But your newImg doesn't have an id attribute let alone an id of rocket.

To fix this, you need to remove img and then set the id attribute of newImg to rocket:

newImg.animate(css, SPEED, function() {
    var old_id = img.attr('id');
    img.remove();
    newImg.attr('id', old_id);
    newImg.removeClass('morpher');
    (callback || function() {})();
});

And then you'll get the shiny black rocket back again: http://jsfiddle.net/ambiguous/W2K9D/

UPDATE: A better approach (as noted by mellamokb) would be to hide the original image and then show it again when you hit the reset button. First, change the reset action to something like this:

$("#resetlink").click(function(){
    clearInterval(timerRocket);
    $("#wrapper").css('top', '250px');
    $('.throbber, .morpher').remove(); // Clear out the new stuff.
    $("#rocket").show();               // Bring the original back.
});

And in the newImg.load function, grab the images original size:

var orig = {
    width: img.width(),
    height: img.height()
};

And finally, the callback for finishing the morphing animation becomes this:

newImg.animate(css, SPEED, function() {
    img.css(orig).hide();
    (callback || function() {})();
});

New and improved: http://jsfiddle.net/ambiguous/W2K9D/1/

The leaking of $('.throbber, .morpher') outside the plugin isn't the best thing ever but it isn't a big deal as long as it is documented.

You can use Java 8 Stream API.

Method distinct is an intermediate operation that filters the stream and allows only distinct values (by default using the Object::equals method) to pass to the next operation.
I wrote an example below for your case,

// Create the list with duplicates.
List<String> listAll = Arrays.asList("CO2", "CH4", "SO2", "CO2", "CH4", "SO2", "CO2", "CH4", "SO2");

// Create a list with the distinct elements using stream.
List<String> listDistinct = listAll.stream().distinct().collect(Collectors.toList());

// Display them to terminal using stream::collect with a build in Collector.
String collectAll = listAll.stream().collect(Collectors.joining(", "));
System.out.println(collectAll); //=> CO2, CH4, SO2, CO2, CH4 etc..
String collectDistinct = listDistinct.stream().collect(Collectors.joining(", "));
System.out.println(collectDistinct); //=> CO2, CH4, SO2

I guess problem is in width attributes in table and td remove 'px' for example

<table border="0" cellpadding="0" cellspacing="0" width="580px" style="background-color: #0290ba;">

Should be

<table border="0" cellpadding="0" cellspacing="0" width="580" style="background-color: #0290ba;">

As your data already in varchar, you have to convert it into date first:

select convert(varchar(10), cast(ts as date), 101) from <your table>

Recently I have read a Java SE 8 Programmer Guide ii Book.

I found something about the difference between AutoCloseable vs Closeable.

The AutoCloseable interface was introduced in Java 7. Before that, another interface existed called Closeable. It was similar to what the language designers wanted, with the following exceptions:

• Closeable restricts the type of exception thrown to IOException.
• Closeable requires implementations to be idempotent.

The language designers emphasize backward compatibility. Since changing the existing interface was undesirable, they made a new one called AutoCloseable. This new interface is less strict than Closeable. Since Closeable meets the requirements for AutoCloseable, it started implementing AutoCloseable when the latter was introduced.

You can also set a default value for the variable, so you don't need to use two "[", which amounts to two processes ("[" is actually a program) instead of one.

It goes by this syntax: ${VARIABLE:-default}.

The whole thing has to be thought in such a way that this "default" value is something distinct from a "valid" value/content.

If that's not possible for some reason you probably need to add a step like checking if there's a value at all, along the lines of "if [ -z $VARIABLE ] ; then echo "the variable needs to be filled"", or "if [ ! -z $VARIABLE ] ; then #everything is fine, proceed with the rest of the script".

You can use as following.

$start_date = date('Y-m-d H:i:s');
$end_date = date("Y-m-d 23:59:59", strtotime('+3 days', strtotime($start_date)));

You can also set days as constant and use like below.

if (!defined('ADD_DAYS')) define('ADD_DAYS','+3 days');
$end_date = date("Y-m-d 23:59:59", strtotime(ADD_DAYS, strtotime($start_date)));

Please make sure that the version of qmake you are using corresponds to the version of QT you want to use.

To be sure, you can just run :

$qmake -v

Your problem seems to be a symptom of a version conflict between QT 3 and 4, as can be seen here :

http://lists.trolltech.com/qt4-preview-feedback/2005-11/thread00013-0.html

To fix this, you can either delete your old install of QT, or specifically point to qmake-qt4 in your Makefile.

You can save to a figure that is 1920x1080 (or 1080p) using:

fig = plt.figure(figsize=(19.20,10.80))

You can also go much higher or lower. The above solutions work well for printing, but these days you want the created image to go into a PNG/JPG or appear in a wide screen format.

According to the PHP manual, data passed to cURL as a string should be URLencoded. See the page for curl_setopt() and search for CURLOPT_POSTFIELDS.

Try this:

In general, you can't do this. UTF-8 is capable of encoding any Unicode code point. ISO-8859-1 can handle only a tiny fraction of them. So, transcoding from ISO-8859-1 to UTF-8 is no problem. Going backwards from UTF-8 to ISO-8859-1 will cause "replacement characters" (�) to appear in your text when unsupported characters are found.

To transcode text:

byte[] latin1 = ...
byte[] utf8 = new String(latin1, "ISO-8859-1").getBytes("UTF-8");

or

byte[] utf8 = ...
byte[] latin1 = new String(utf8, "UTF-8").getBytes("ISO-8859-1");

You can exercise more control by using the lower-level Charset APIs. For example, you can raise an exception when an un-encodable character is found, or use a different character for replacement text.

1. check the list of installed apk's (following command also list the path where it is installed and package name). adb shell pm list packages -f
2. use adb pull /package_path/package name /path_in_pc (package path and package name one can get from above command 1.)

Your code looks correct. My suggestion is that the database already thinks it's upgraded. If you executed the project after incrementing the version number, but before adding the execSQL call, the database on your test device/emulator may already believe it's at version 2.

A quick way to verify this would be to change the version number to 3 -- if it upgrades after that, you know it was just because your device believed it was already upgraded.

These days, Android Studio setup do not provide SDK as the part of original package.

In the context of windows, when you start Android Studio 1.3.1, you see the error message saying no sdk found. You just have to proceed and provide the path where sdk can be downloaded. And you are done.

You can also use an exit variable if you want your code to be a bit more readable:

DECLARE @Flag int = 0
DECLARE @Done bit = 0

WHILE @Done = 0 BEGIN
    SET @Flag = @Flag + 1
    PRINT @Flag
    IF @Flag >= 5 SET @Done = 1
END

This would probably be more relevant when you have a more complicated loop and are trying to keep track of the logic. As stated loops are expensive so try and use other methods if you can.

  FILE *fp;
  char path[1035];

  /* Open the command for reading. */
  fp = popen("/bin/ls /etc/", "r");
  if (fp == NULL) {
    printf("Failed to run command\n" );
    exit(1);
  }

  /* Read the output a line at a time - output it. */
  while (fgets(path, sizeof(path), fp) != NULL) {
    printf("%s", path);
  }

  /* close */
  pclose(fp);

  return 0;
}

Use -Xms1024m -Xmx1024m to control your heap size (1024m is only for demonstration, the exact number depends your system memory). Setting minimum and maximum heap size to the same is usually a best practice since JVM doesn't have to increase heap size at runtime.

For the point that 'returns the value as soon as you find the first row/record that meets the requirements and NOT iterating other rows', the following code would work:

def pd_iter_func(df):
    for row in df.itertuples():
        # Define your criteria here
        if row.A > 4 and row.B > 3:
            return row

It is more efficient than Boolean Indexing when it comes to a large dataframe.

To make the function above more applicable, one can implements lambda functions:

def pd_iter_func(df: DataFrame, criteria: Callable[[NamedTuple], bool]) -> Optional[NamedTuple]:
    for row in df.itertuples():
        if criteria(row):
            return row

pd_iter_func(df, lambda row: row.A > 4 and row.B > 3)

As mentioned in the answer to the 'mirror' question, pandas.Series.idxmax would also be a nice choice.

def pd_idxmax_func(df, mask):
    return df.loc[mask.idxmax()]

pd_idxmax_func(df, (df.A > 4) & (df.B > 3))

Using Ubuntu 12.04 it appears to work fine for me:

What error are you getting exactly? - double check you've spelt psycopg right - that's quite often a gotcha... and it never hurts to run an apt-get update to make sure your repo. is up to date.

AttributeError is raised when attribute of the object is not available.

An attribute reference is a primary followed by a period and a name:

attributeref ::= primary "." identifier

To return a list of valid attributes for that object, use dir(), e.g.:

dir(scipy)

So probably you need to do simply: import scipy.sparse

Two things must be done.

First add the directory to be included:

target_include_directories(test PRIVATE ${YOUR_DIRECTORY})

In case you are stuck with a very old CMake version (2.8.10 or older) without support for target_include_directories, you can also use the legacy include_directories instead:

include_directories(${YOUR_DIRECTORY})

Then you also must add the header files to the list of your source files for the current target, for instance:

set(SOURCES file.cpp file2.cpp ${YOUR_DIRECTORY}/file1.h ${YOUR_DIRECTORY}/file2.h)
add_executable(test ${SOURCES})

This way, the header files will appear as dependencies in the Makefile, and also for example in the generated Visual Studio project, if you generate one.

How to use those header files for several targets:

set(HEADER_FILES ${YOUR_DIRECTORY}/file1.h ${YOUR_DIRECTORY}/file2.h)

add_library(mylib libsrc.cpp ${HEADER_FILES})
target_include_directories(mylib PRIVATE ${YOUR_DIRECTORY})
add_executable(myexec execfile.cpp ${HEADER_FILES})
target_include_directories(myexec PRIVATE ${YOUR_DIRECTORY})

String[] mailAddressTo = new String[3];    
mailAddressTo[0] = emailId_1;    
mailAddressTo[1] = emailId_2;    
mailAddressTo[2] = "[email protected]";

InternetAddress[] mailAddress_TO = new InternetAddress[mailAddressTo.length];

for (int i = 0; i < mailAddressTo.length; i++)
{
    mailAddress_TO[i] = new InternetAddress(mailAddressTo[i]);
}

message.addRecipients(Message.RecipientType.TO, mailAddress_TO);ress_TO = new InternetAddress[mailAddressTo.length]; 

On Mac (and Linux I think), after you have created your AVD, you can make an alias: alias run-android='~/Library/Android/sdk/tools/emulator -avd ${YOUR_AVD_NAME} &'

Note: the execution of the alias will not lock your terminal, if you want that, just remove the last '&'.

Run emulator it self will give you an error because he expect that, in your current position, you have: /emulator/qemu/${YOUR_PATFORM}/qemu-system-x86_64' to start the emulator.

I faced similar problem a while ago and decided to write Eclipse plug-in that shows complete build path dependency tree of a Java project (although not in graphic mode - result is written into file). The plug-in's sources are here http://github.com/PetrGlad/dependency-tree

Choose which DI to inject stuff into Jersey:

Spring 4:

<dependency>
  <groupId>org.glassfish.jersey.ext</groupId>
  <artifactId>jersey-spring4</artifactId>
</dependency>

Spring 3:

<dependency>
  <groupId>org.glassfish.jersey.ext</groupId>
  <artifactId>jersey-spring3</artifactId>
</dependency>

HK2:

<dependency>
    <groupId>org.glassfish.jersey.inject</groupId>
    <artifactId>jersey-hk2</artifactId>
</dependency>

You could try always sending the first 4 bytes of your data as data size and then read complete data in one shot. Use the below functions on both client and server-side to send and receive data.

def send_data(conn, data):
    serialized_data = pickle.dumps(data)
    conn.sendall(struct.pack('>I', len(serialized_data)))
    conn.sendall(serialized_data)


def receive_data(conn):
    data_size = struct.unpack('>I', conn.recv(4))[0]
    received_payload = b""
    reamining_payload_size = data_size
    while reamining_payload_size != 0:
        received_payload += conn.recv(reamining_payload_size)
        reamining_payload_size = data_size - len(received_payload)
    data = pickle.loads(received_payload)

    return data

you could find sample program at https://github.com/vijendra1125/Python-Socket-Programming.git

The token won't work if it was supplied by a different controller. E.g. it won't work if the view was returned by the Accounts controller, but you POST to the Clients controller.

I don't know how good or bad this is, but you can try something like this:

try:
    obj = Model.objects.get(id=some_id)
except Model.DoesNotExist:
    obj = Model.objects.create()
obj.__dict__.update(your_fields_dict) 
obj.save()

All above answers are not working for me. So, i have fixed by mentioning the label with screenOrientation like below. Now everything fine

<activity android:name=".activity.VideoWebViewActivity"
        android:label="@string/app_name"
        android:configChanges="orientation|screenSize"/>

try: ->unique('column')

example:

$users = User::get()->unique('column');

To generate graph in png format you need to Install following dependent packages

sudo apt-get install libpng-dev
sudo apt-get install libfreetype6-dev

Ubuntu https://apps.ubuntu.com/cat/applications/libpng12-0/ or using following command

sudo apt-get install libpng12-0

From RFC2616 section 14.9.1

You can try converting your image from tiff to PNG, here is how to do it:

import com.sun.media.jai.codec.ImageCodec;
import com.sun.media.jai.codec.ImageDecoder;
import com.sun.media.jai.codec.ImageEncoder;
import com.sun.media.jai.codec.PNGEncodeParam;
import com.sun.media.jai.codec.TIFFDecodeParam;
import java.awt.image.RenderedImage;
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import javaxt.io.Image;

public class ImgConvTiffToPng {

    public static byte[] convert(byte[] tiff) throws Exception {

        byte[] out = new byte[0];
        InputStream inputStream = new ByteArrayInputStream(tiff);

        TIFFDecodeParam param = null;

        ImageDecoder dec = ImageCodec.createImageDecoder("tiff", inputStream, param);
        RenderedImage op = dec.decodeAsRenderedImage(0);

        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

        PNGEncodeParam jpgparam = null;
        ImageEncoder en = ImageCodec.createImageEncoder("png", outputStream, jpgparam);
        en.encode(op);
        outputStream = (ByteArrayOutputStream) en.getOutputStream();
        out = outputStream.toByteArray();
        outputStream.flush();
        outputStream.close();

        return out;

    }

Same issue i faced , when copy the project from another system. In my case i fixed this issue:

delete everythings from inside Bin folder. Clean & Rebuild the app again

Hope this will help.

Based on your comments to orip's post, I guess this is what happened:

1. You edited __init__.py on windows.
2. The windows editor added something non-printing, perhaps a carriage-return (end-of-line in Windows is CR/LF; in unix it is LF only), or perhaps a CTRL-Z (windows end-of-file).
3. You used WinSCP to copy the file to your unix box.
4. WinSCP thought: "This has something that's not basic text; I'll put a .bin extension to indicate binary data."
5. The missing __init__.py (now called __init__.py.bin) means python doesn't understand toolkit as a package.
6. You create __init__.py in the appropriate directory and everything works... ?

From High Performance Android Apps book (page 157):

• what we see is equivalent of adb shell dumpsys cpuinfo command
• Numbers are showing CPU load over 1 minute, 5 minutes and 15 minutes (from the left)
• Colors are showing time spent by CPU in user space (green), kernel (red) and IO interrupt (blue)

If you want to hunt this error, use the main thread checker pause on issues checkbox. Fixing it is easy most of the times, dispatching the problematic line in the main queue.

Using Guava (r07) you can do this:

for(char c : Lists.charactersOf(someString)) { ... }

This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf returns a view of the string as a List.

Pure Virtual Function

try this code

#include <iostream>
using namespace std;
class aClassWithPureVirtualFunction
{

public:

    virtual void sayHellow()=0;

};

class anotherClass:aClassWithPureVirtualFunction
{

public:

    void sayHellow()
    {

        cout<<"hellow World";
    }

};
int main()
{
    //aClassWithPureVirtualFunction virtualObject;
    /*
     This not possible to create object of a class that contain pure virtual function
    */
    anotherClass object;
    object.sayHellow();
}

In class anotherClass remove the function sayHellow and run the code. you will get error!Because when a class contain a pure virtual function, no object can be created from that class and it is inherited then its derived class must implement that function.

Virtual function

try another code

#include <iostream>
using namespace std;
class aClassWithPureVirtualFunction
{

public:

    virtual void sayHellow()
    {
        cout<<"from base\n";
    }

};

class anotherClass:public aClassWithPureVirtualFunction
{

public:

    void sayHellow()
    {

        cout<<"from derived \n";
    }

};
int main()
{
    aClassWithPureVirtualFunction *baseObject=new aClassWithPureVirtualFunction;
    baseObject->sayHellow();///call base one

    baseObject=new anotherClass;
    baseObject->sayHellow();////call the derived one!

}

Here the sayHellow function is marked as virtual in base class.It say the compiler that try searching the function in derived class and implement the function.If not found then execute the base one.Thanks

Use this line simply inside your head with

       window.location.reload(true);

It will load your current page or view.

If you need exactly m rows, realistically you'll generate your subset of IDs outside of SQL. Most methods require at some point to select the "nth" entry, and SQL tables are really not arrays at all. The assumption that the keys are consecutive in order to just join random ints between 1 and the count is also difficult to satisfy — MySQL for example doesn't support it natively, and the lock conditions are... tricky.

Here's an O(max(n, m lg n))-time, O(n)-space solution assuming just plain BTREE keys:

1. Fetch all values of the key column of the data table in any order into an array in your favorite scripting language in O(n)
2. Perform a Fisher-Yates shuffle, stopping after m swaps, and extract the subarray [0:m-1] in ?(m)
3. "Join" the subarray with the original dataset (e.g. SELECT ... WHERE id IN (<subarray>)) in O(m lg n)

Any method that generates the random subset outside of SQL must have at least this complexity. The join can't be any faster than O(m lg n) with BTREE (so O(m) claims are fantasy for most engines) and the shuffle is bounded below n and m lg n and doesn't affect the asymptotic behavior.

In Pythonic pseudocode:

ids = sql.query('SELECT id FROM t')
for i in range(m):
  r = int(random() * (len(ids) - i))
  ids[i], ids[i + r] = ids[i + r], ids[i]

results = sql.query('SELECT * FROM t WHERE id IN (%s)' % ', '.join(ids[0:m-1])

The facade is another Request class, access it with the full path:

$input = \Request::all();

From laravel 5 you can also access it through the request() function:

$input = request()->all();
