I faced the same problem while testing the changes in Symfony 4.3.2

I lowered the log level to INFO

And ran the test again

And the logged showed this:

console.ERROR: Error thrown while running command "doctrine:schema:create". Message: "[Semantical Error] The annotation "@ORM\Id" in property App\Entity\Common::$id was never imported. Did you maybe forget to add a "use" statement for this annotation?" {"exception":"[object] (Doctrine\\Common\\Annotations\\AnnotationException(code: 0): [Semantical Error] The annotation \"@ORM\\Id\" in property App\\Entity\\Common::$id was never imported. Did you maybe forget to add a \"use\" statement for this annotation? at C:\\xampp\\htdocs\\dirty7s\\vendor\\doctrine\\annotations\\lib\\Doctrine\\Common\\Annotations\\AnnotationException.php:54)","command":"doctrine:schema:create","message":"[Semantical Error] The annotation \"@ORM\\Id\" in property App\\Entity\\Common::$id was never imported. Did you maybe forget to add a \"use\" statement for this annotation?"} []

This means that some error in the code causes the:

Doctrine\ORM\ORMException: The EntityManager is closed.

So it is a good idea to check the log

You may have come here for advice on when to use persist and when to use merge. I think that it depends the situation: how likely is it that you need to create a new record and how hard is it to retrieve persisted data.

Let's presume you can use a natural key/identifier.

• Data needs to be persisted, but once in a while a record exists and an update is called for. In this case you could try a persist and if it throws an EntityExistsException, you look it up and combine the data:

  try { entityManager.persist(entity) }

  catch(EntityExistsException exception) { /* retrieve and merge */ }

• Persisted data needs to be updated, but once in a while there is no record for the data yet. In this case you look it up, and do a persist if the entity is missing:

  entity = entityManager.find(key);

  if (entity == null) { entityManager.persist(entity); }

  else { /* merge */ }

If you don't have natural key/identifier, you'll have a harder time to figure out whether the entity exist or not, or how to look it up.

The merges can be dealt with in two ways, too:

1. If the changes are usually small, apply them to the managed entity.
2. If changes are common, copy the ID from the persisted entity, as well as unaltered data. Then call EntityManager::merge() to replace the old content.

EntityManager.persist() makes an entity persistent whereas EntityManager.flush() actually runs the query on your database.

So, when you call EntityManager.flush(), queries for inserting/updating/deleting associated entities are executed in the database. Any constraint failures (column width, data types, foreign key) will be known at this time.

The concrete behaviour depends on whether flush-mode is AUTO or COMMIT.

With plain JPA, assuming that you have a PersistenceProvider implementation (e.g. Hibernate), you can use the PersistenceProvider#createContainerEntityManagerFactory(PersistenceUnitInfo info, Map map) method to bootstrap an EntityManagerFactory without needing a persistence.xml.

However, it's annoying that you have to implement the PersistenceUnitInfo interface, so you are better off using Spring or Hibernate which both support bootstrapping JPA without a persistence.xml file:

this.nativeEntityManagerFactory = provider.createContainerEntityManagerFactory(
    this.persistenceUnitInfo, 
    getJpaPropertyMap()
);

Where the PersistenceUnitInfo is implemented by the Spring-specific MutablePersistenceUnitInfo class.

You don't need both hibernate.cfg.xml and persistence.xml in this case. Have you tried removing hibernate.cfg.xml and mapping everything in persistence.xml only?

But as the other answer also pointed out, this is not okay like this:

@Id
@JoinColumn(name = "categoria") 
private String id;

Didn't you want to use @Column instead?

That depends on what you want to do, but as you said, getting an entity reference using find() and then just updating that entity is the easiest way to do that.

I'd not bother about performance differences of the various methods unless you have strong indications that this really matters.

There is a great book called Chaos and Fractals that has simple example code at the end of each chapter that implements some fractal or other example. A long time ago when I read that book, I converted each sample program (in some Basic dialect) into a Java applet that runs on a web page. The applets are here: http://hewgill.com/chaos-and-fractals/

One of the samples is a simple Mandelbrot implementation.

The answer to your question is ultimately, it depends. The links in that navigation are added via different layout XML files. Here's the code that first defines the block in layout/customer.xml. Notice that it also defines some links to add to the menu:

<block type="customer/account_navigation" name="customer_account_navigation" before="-" template="customer/account/navigation.phtml">
    <action method="addLink" translate="label" module="customer"><name>account</name><path>customer/account/</path><label>Account Dashboard</label></action>
    <action method="addLink" translate="label" module="customer"><name>account_edit</name><path>customer/account/edit/</path><label>Account Information</label></action>
    <action method="addLink" translate="label" module="customer"><name>address_book</name><path>customer/address/</path><label>Address Book</label></action>
</block>

Other menu items are defined in other layout files. For example, the Reviews module uses layout/review.xml to define its layout, and contains the following:

<customer_account>
    <!-- Mage_Review -->
    <reference name="customer_account_navigation">
        <action method="addLink" translate="label" module="review"><name>reviews</name><path>review/customer</path><label>My Product Reviews</label></action>
    </reference>
</customer_account>

To remove this link, just comment out or remove the <action method=...> tag and the menu item will disappear. If you want to find all menu items at once, use your favorite file search and find any instances of name="customer_account_navigation", which is the handle that Magento uses for that navigation block.

log.retention.hours is a property of a broker which is used as a default value when a topic is created. When you change configurations of currently running topic using kafka-topics.sh, you should specify a topic-level property.

A topic-level property for log retention time is retention.ms.

From Topic-level configuration in Kafka 0.8.1 documentation:

• Property: retention.ms
• Default: 7 days
• Server Default Property: log.retention.minutes
• Description: This configuration controls the maximum time we will retain a log before we will discard old log segments to free up space if we are using the "delete" retention policy. This represents an SLA on how soon consumers must read their data.

So the correct command depends on the version. Up to 0.8.2 (although docs still show its use up to 0.10.1) use kafka-topics.sh --alter and after 0.10.2 (or perhaps from 0.9.0 going forward) use kafka-configs.sh --alter

$ bin/kafka-topics.sh --zookeeper zk.yoursite.com --alter --topic as-access --config retention.ms=86400000
 

You can check whether the configuration is properly applied with the following command.

$ bin/kafka-topics.sh --describe --zookeeper zk.yoursite.com --topic as-access

Then you will see something like below.

Topic:as-access  PartitionCount:3  ReplicationFactor:3  Configs:retention.ms=86400000

Button ok= view.findViewById(R.id.btSettingOK);
Fragment me=this;
ok.setOnClickListener( new View.OnClickListener(){
    public void onClick(View v){
     getActivity().getFragmentManager().beginTransaction().remove(me).commit();
    }
});

I faced this same issue when I needed to load location data that I had serialized into the database from the google places API. Generally I would want the whole thing so it works with maps but I didn't want to have to specify all of the fields every time.

I was working in Ruby so I can't give you the PHP implementation but the principle should be the same.

I defined a custom scalar type called JSON which just returns a literal JSON object.

The ruby implementation was like so (using graphql-ruby)

module Graph
  module Types
    JsonType = GraphQL::ScalarType.define do
      name "JSON"
      coerce_input -> (x) { x }
      coerce_result -> (x) { x }
    end
  end
end

Then I used it for our objects like so

field :location, Types::JsonType

I would use this very sparingly though, using it only where you know you always need the whole JSON object (as I did in my case). Otherwise it is defeating the object of GraphQL more generally speaking.

Maybe you received an error when working with this table before. You can rename the table and try to remove it again.

ALTER TABLE `area` RENAME TO `area2`;
DROP TABLE IF EXISTS `area2`;

You start recording by q<letter> and you can end it by typing q again.

Recording is a really useful feature of Vim.

It records everything you type. You can then replay it simply by typing @<letter>. Record search, movement, replacement...

One of the best feature of Vim IMHO.

You can use this code into viewDidLoad or viewDidAppear where your table being created:

// Remove blank space on header of table view
 videoListUITableView.contentInset = UIEdgeInsetsZero;

// The iOS device = iPhone or iPod Touch
CGSize iOSDeviceScreenSize = [[UIScreen mainScreen] bounds].size;

// Set the height of the table on the basis of number of rows
videoListUITableView.frame = CGRectMake(videoListUITableView.frame.origin.x, videoListUITableView.frame.origin.y, videoListUITableView.frame.size.width, iOSDeviceScreenSize.height-100);



// Hide those cell which doesn't contain any kind of data
self.videoListUITableView.tableFooterView = [[UIView alloc] init];

The accepted answer works for columns that are of datatype string. For completeness: I come across this question when searching how to do this when the columns are of datatypes: date and time.

df.apply(lambda r : pd.datetime.combine(r['date_column_name'],r['time_column_name']),1)

I'd like to add the following to Shay Levy's correct answer: You can make your life easier if you create a little batch script run.cmd to launch your powershell script:

@echo off & setlocal
set batchPath=%~dp0
powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" "MY-PC"

Put it in the same path as SQLExecutor.ps1 and from now on you can run it by simply double-clicking on run.cmd.

Note:

• If you require command line arguments inside the run.cmd batch, simply pass them as %1 ... %9 (or use %* to pass all parameters) to the powershell script, i.e.
  powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" %*

• The variable batchPath contains the executing path of the batch file itself (this is what the expression %~dp0 is used for). So you just put the powershell script in the same path as the calling batch file.

The following will give you the hex encoding for the low byte of each character, which looks like what you're asking for:

StringBuilder sb = new StringBuilder();
foreach (char c in asciiString)
{
    uint i = (uint)c;
    sb.AppendFormat("{0:X2}", (i & 0xff));
}
return sb.ToString();

Need to see whether you got ant folder moved by mistake or unknowingly. It is set in environment variables.I resolved this once as mentioned below.

I removed ant folder by mistake and placed in another folder.I went to command prompt and typed "path". It has given me path as "F:\apache-ant-1.9.4\". So I moved the ant back to F drive and it resolved the issue.

Without you providing any specific error message, it's hard to give specific suggestions.

However, I was using the same example and was getting a permissions exception on File.OpenWrite - using the localFileName variable, because using Path.GetFile was pointing to a location that obviously would not have permissions for opening a file > C:\ProgramFiles\IIS(Express)\filename.doc

I found that using System.IO.Path.GetFileName is not correct, use System.IO.Path.GetFullPath instead, point to your file starting with "C:\..."

Also open your solution in FileExplorer and grant permissions to asp.net for the file or any folders holding the file. I was able to download my file at that point.

I also prefer decorator syntax to deriving from metaclass. My two cents:

from typing import Callable, Dict, Set


def singleton(cls_: Callable) -> type:
    """ Implements a simple singleton decorator
    """
    class Singleton(cls_):  # type: ignore
        __instances: Dict[type, object] = {}
        __initialized: Set[type] = set()

        def __new__(cls, *args, **kwargs):
            if Singleton.__instances.get(cls) is None:
                Singleton.__instances[cls] = super().__new__(cls, *args, **kwargs)
            return Singleton.__instances[cls]

        def __init__(self, *args, **kwargs):
            if self.__class__ not in Singleton.__initialized:
                Singleton.__initialized.add(self.__class__)
                super().__init__(*args, **kwargs)

    return Singleton


@singleton
class MyClass(...):
    ...

This has some benefits above other decorators provided:

• isinstance(MyClass(), MyClass) will still work (returning a function from the clausure instead of a class will make isinstance to fail)
• property, classmethod and staticmethod will still work as expected
• __init__() constructor is executed only once
• You can inherit from your decorated class (useless?) using @singleton again

Cons:

• print(MyClass().__class__.__name__) will return Singleton instead od MyClass. If you still need this, I recommend using a metaclass as suggested above.

If you need a different instance based on constructor parameters this solution needs to be improved (solution provided by siddhesh-suhas-sathe provides this).

Finally, as other suggested, consider using a module in python. Modules are objects. You can even pass them in variables and inject them in other classes.

Try using an ontouch listener instead of a clicklistener.

You can use pgrep with -f (full command line) and -l (long description):

pgrep -l -f PatternOfProcess

This method has a crucial difference with any of the other responses: it works on CygWin, so you can use it to obtain the full command line of any process running under Windows (execute as elevated if you want data about any elevated/admin process). Any other method for doing this on Windows is more awkward ( for example ).
Furthermore: in my tests, the pgrep way has been the only system that worked to obtain the full path for scripts running inside CygWin's python.

Use [Dispatcher.Invoke(DispatcherPriority, Delegate)] to change the UI from another thread or from background.

Step 1. Use the following namespaces

using System.Windows;
using System.Threading;
using System.Windows.Threading;

Step 2. Put the following line where you need to update UI

Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate
{
    //Update UI here
}));

Syntax

[BrowsableAttribute(false)]
public object Invoke(
  DispatcherPriority priority,
  Delegate method
)

Parameters

priority

Type: System.Windows.Threading.DispatcherPriority

The priority, relative to the other pending operations in the Dispatcher event queue, the specified method is invoked.

method

Type: System.Delegate

A delegate to a method that takes no arguments, which is pushed onto the Dispatcher event queue.

Return Value

Type: System.Object

The return value from the delegate being invoked or null if the delegate has no return value.

Version Information

Available since .NET Framework 3.0

Similar setup, identical problem. Some installations would work, but most would start redirecting (http 302) to /Account/Login?ReturnUrl=%2f after a successful login, even though we're not using Forms Authentication. In my case after trying everything else, the solution was to switch the Application Pool Managed Pipeline Mode from from Integrated to Classic, which cleared up the problem immediately.

Java is a server side language, whereas javascript is a client side language. Both cannot communicate. If you have setup some server side script using Java you could use AJAX on the client in order to send an asynchronous request to it and thus invoke any possible Java functions. For example if you use jQuery as js framework you may take a look at the $.ajax() method. Or if you wanted to do it using plain javascript, here's a tutorial.

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

I found a lot of responses dealing with arrays but not with a json object. My solution was simply to iterate through the object once while incrementing a counter and then when iterating through the object to perform your code you can increment a second counter. Then you simply compare the two counters together and get your solution. I know it's a little clunky but I haven't found a more elegant solution so far. This is my example code:

var flag1 = flag2 = 0;

$.each( object, function ( i, v ) { flag1++; });

$.each( object, function ( ky, val ) {

     /*
        Your code here
     */
     flag2++;
});

if(flag1 === flag2) {
   your function to call at the end of the iteration
}

Like I said, it's not the most elegant, but it works and it works well and I haven't found a better solution just yet.

The only standard field Error object has is the message property. (See MDN, or EcmaScript Language Specification, section 15.11) Everything else is platform specific.

Mosts environments set the stack property, but fileName and lineNumber are practically useless to be used in inheritance.

So, the minimalistic approach is:

function MyError(message) {
    this.name = 'MyError';
    this.message = message;
    this.stack = (new Error()).stack;
}
MyError.prototype = new Error;  // <-- remove this if you do not 
                                //     want MyError to be instanceof Error

You could sniff the stack, unshift unwanted elements from it and extract information like fileName and lineNumber, but doing so requires information about the platform JavaScript is currently running upon. Most cases that is unnecessary -- and you can do it in post-mortem if you really want.

Safari is a notable exception. There is no stack property, but the throw keyword sets sourceURL and line properties of the object that is being thrown. Those things are guaranteed to be correct.

Test cases I used can be found here: JavaScript self-made Error object comparison.

If your week number is in A1 and the year is in A2, following snippet could give you dates of full week

=$A$1*7+DATE($B$1,1,-4) through =$A$1*7+DATE($B$1,1,2)

Of course complete the series from -4 to 2 and you'll have dates starting Sunday through Saturday.

Hope this helps.

You could create your own .xml animation files to fade in a new Activity and fade out the current Activity:

fade_in.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="0.0" android:toAlpha="1.0"
           android:duration="500" />

fade_out.xml

<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
           android:interpolator="@android:anim/accelerate_interpolator"
           android:fromAlpha="1.0" android:toAlpha="0.0"
           android:fillAfter="true"
           android:duration="500" />

Use it in code like that: (Inside your Activity)

Intent i = new Intent(this, NewlyStartedActivity.class);
startActivity(i);
overridePendingTransition(R.anim.fade_in, R.anim.fade_out);

The above code will fade out the currently active Activity and fade in the newly started Activity resulting in a smooth transition.

UPDATE: @Dan J pointed out that using the built in Android animations improves performance, which I indeed found to be the case after doing some testing. If you prefer working with the built in animations, use:

overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);

Notice me referencing android.R instead of R to access the resource id.

UPDATE: It is now common practice to perform transitions using the Transition class introduced in API level 19.

assertNotNull asserts that the object is not null. If it is null the test fails, so you want that.

Another approach when you have many updates would be to use COALESCE:

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = COALESCE(@ABC, [ABC]),
    [ABCD] = COALESCE(@ABCD, [ABCD])

I imagine this forum posting, which I quote fully below, should answer the question.

Inside a procedure, function, or trigger definition, or in a dynamic SQL statement (embedded in a host program):

BEGIN ATOMIC
 DECLARE example VARCHAR(15) ;
 SET example = 'welcome' ;
 SELECT *
 FROM   tablename
 WHERE  column1 = example ;
END

or (in any environment):

WITH t(example) AS (VALUES('welcome'))
SELECT *
FROM   tablename, t
WHERE  column1 = example

or (although this is probably not what you want, since the variable needs to be created just once, but can be used thereafter by everybody although its content will be private on a per-user basis):

CREATE VARIABLE example VARCHAR(15) ;
SET example = 'welcome' ;
SELECT *
FROM   tablename
WHERE  column1 = example ;

Every time the randint() method is called inside the for loop a different seed is set and a sequence is generated according to the time. But as for loop runs fast in your computer in a small time the seed is almost same and a very similar sequence is generated to the past one due to the time. So setting the seed outside the randint() method is enough.

package main

import (
    "bytes"
    "fmt"
    "math/rand"
    "time"
)

var r = rand.New(rand.NewSource(time.Now().UTC().UnixNano()))
func main() {
    fmt.Println(randomString(10))
}

func randomString(l int) string {

    var result bytes.Buffer
    var temp string
    for i := 0; i < l; {
        if string(randInt(65, 90)) != temp {
            temp = string(randInt(65, 90))
            result.WriteString(temp)
            i++
        }
    }
    return result.String()
}

func randInt(min int, max int) int {
    return min + r.Intn(max-min)
}

1. Set maxFiles Count: maxFiles: 1
2. In maxfilesexceeded event, clear all files and add a new file:

event: Called for each file that has been rejected because the number of files exceeds the maxFiles limit.

var myDropzone = new Dropzone("div#yourDropzoneID", { url: "/file/post", 
uploadMultiple: false, maxFiles: 1 });

myDropzone.on("maxfilesexceeded", function (file) {
    myDropzone.removeAllFiles();
    myDropzone.addFile(file);
});

If you want to use Open source then there are many options for you. But python is best among them as it has many libraries and a super awesome community. These are a few reasons which might change your mind:

• Python is very good but it is a interpreted language which makes it slow. But many accelerator and caching services are there which partly solve this problem.

• If you are thinking about rapid development then Ruby on Rails is best among all. The main motto of this(ROR) framework is to give a comfortable experience to the developers. If you compare Ruby and Python both have nearly the same syntax.

• Google App Engine is very good service but it will bind you in its scope, you don't get chance to experiment new things. Instead of it you can use Digital Ocean cloud which will only take $5/Month charge for its simplest droplet. Heroku is another free service where you can deploy your product.

• Yes! Yes! What you heard is totally correct but here are some examples which are using other technologies

  • Rails: Github, Twitter(previously), Shopify, Airbnb, Slideshare, Heroku etc.
  • PHP: Facebook, Wikipedia, Flickr, Yahoo, Tumbler, Mailchimp etc.

Conclusion is a framework or language won't do everything for you. A better architecture, designing and strategy will give you a scalable website. Instagram is the biggest example, this small team is managing such huge data. Here is one blog about its architecture must read it.

In my case, I was using the ASP.NET Identity Framework. I had used the built in UserManager.FindByNameAsync method to retrieve an ApplicationUser entity. I then tried to reference this entity on a newly created entity on a different DbContext. This resulted in the exception you originally saw.

I solved this by creating a new ApplicationUser entity with only the Id from the UserManager method and referencing that new entity.

SELECT  username, AVG(rating) as TheAverage, COUNT(*) as TheCount
FROM    ratings
        WHERE month='Aug'
        AND username COLLATE latin1_general_ci IN
        (
        SELECT  username
        FROM    users
        WHERE   gender = 1
        )
GROUP BY
        username
HAVING
        TheCount > 4
ORDER BY
        TheAverage DESC, TheCount DESC;

According to the HTML standard, you can not. The only valid values for the method attribute are get and post, corresponding to the GET and POST HTTP methods. <form method="put"> is invalid HTML and will be treated like <form>, i.e. send a GET request.

Instead, many frameworks simply use a POST parameter to tunnel the HTTP method:

<form method="post" ...>
  <input type="hidden" name="_method" value="put" />
...

Of course, this requires server-side unwrapping.

If you're doing computations:

• You have to check isCancelled() periodically.

If you're doing a HTTP request:

• Save the instance of your HttpGet or HttpPost somewhere (eg. a public field).
• After calling cancel, call request.abort(). This will cause IOException be thrown inside your doInBackground.

In my case, I had a connector class which I used in various AsyncTasks. To keep it simple, I added a new abortAllRequests method to that class and called this method directly after calling cancel.

I had the same problem with my IntelliJ Maven build. My "solution" was to go into the build tools and remove the build tools 24.0.0 folder. I found it in the {android-sdk-location}/build-tools/ directory. This is not a long term fix, but this should at least get your project building again. Upgrading to Java 8 as many have suggested will be better long term.

Plunker

$scope.remove = function(item) { 
    $scope.cards.splice(0, 1);     
  }

Made changes to .. now it will remove from the top

It works with just this:

.slideContainer {
    white-space: nowrap;
}
.slide { 
    display: inline-block;
    width: 600px;
    white-space: normal;
}

I did originally have float : left; and that prevented it from working correctly.

Thanks for posting this solution.

Basically speaking, the answer is: it depends. There are many many benchmarks focusing on different kinds of application.

My benchmark on my app is: gcc > icc > clang.

There are rare IO, but many CPU float and data structure operations.

compile flags is -Wall -g -DNDEBUG -O3.

Usually, we define classes for this.

class XClass( object ):
   def __init__( self ):
       self.myAttr= None

x= XClass()
x.myAttr= 'magic'
x.myAttr

However, you can, to an extent, do this with the setattr and getattr built-in functions. However, they don't work on instances of object directly.

>>> a= object()
>>> setattr( a, 'hi', 'mom' )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'object' object has no attribute 'hi'

They do, however, work on all kinds of simple classes.

class YClass( object ):
    pass

y= YClass()
setattr( y, 'myAttr', 'magic' )
y.myAttr

This is what I did to extract the piece of the directory:

for path in file_list:
  directories = path.rsplit('\\')
  directories.reverse()
  line_replace_add_directory = line_replace+directories[2]

Thank you for your help.

append( ) function and spread operator

Two slices can be concatenated using append method in the standard golang library. Which is similar to the variadic function operation. So we need to use ...

package main

import (
    "fmt"
)

func main() {
    x := []int{1, 2, 3}
    y := []int{4, 5, 6}
    z := append([]int{}, append(x, y...)...)
    fmt.Println(z)
}

output of the above code is: [1 2 3 4 5 6]

Running a Python Script in the Background

First, you need to add a shebang line in the Python script which looks like the following:

#!/usr/bin/env python3

This path is necessary if you have multiple versions of Python installed and /usr/bin/env will ensure that the first Python interpreter in your $$PATH environment variable is taken. You can also hardcode the path of your Python interpreter (e.g. #!/usr/bin/python3), but this is not flexible and not portable on other machines. Next, you’ll need to set the permissions of the file to allow execution:

chmod +x test.py

Now you can run the script with nohup which ignores the hangup signal. This means that you can close the terminal without stopping the execution. Also, don’t forget to add & so the script runs in the background:

nohup /path/to/test.py &

If you did not add a shebang to the file you can instead run the script with this command:

nohup python /path/to/test.py &

The output will be saved in the nohup.out file, unless you specify the output file like here:

nohup /path/to/test.py > output.log &
nohup python /path/to/test.py > output.log &

If you have redirected the output of the command somewhere else - including /dev/null - that's where it goes instead.

# doesn't create nohup.out

nohup command >/dev/null 2>&1   

If you're using nohup, that probably means you want to run the command in the background by putting another & on the end of the whole thing:

# runs in background, still doesn't create nohup.out

 nohup command >/dev/null 2>&1 &  

You can find the process and its process ID with this command:

ps ax | grep test.py

# or
# list of running processes Python

ps -fA | grep python

ps stands for process status

If you want to stop the execution, you can kill it with the kill command:

kill PID

Another option:

    var topController:UIViewController = UIApplication.shared.keyWindow!.rootViewController!
    while ((topController.presentedViewController) != nil) {
        topController = topController.presentedViewController!
    }
    topController.present(alert, animated:true, completion:nil)

define class in models.py and a function in it.

class all_products(models.Model):
    def get_all_products():
        items = []
        with open('EXACT FILE PATH OF YOUR CSV FILE','r') as fp:
            # You can also put the relative path of csv file
            # with respect to the manage.py file
            reader1 = csv.reader(fp, delimiter=';')
            for value in reader1:
                items.append(value)
        return items

You can access ith element in the list as items[i]

The simplest approach is to encapsulate the two values together into a type which has both the image and the file. Then build an ArrayList of that and shuffle it.

That improves encapsulation as well, giving you the property that you'll always have the same number of files as images automatically.

An alternative if you really don't like that idea would be to write the shuffle code yourself (there are plenty of examples of a modified Fisher-Yates shuffle in Java, including several on Stack Overflow I suspect) and just operate on both lists at the same time. But I'd strongly recommend going with the "improve encapsulation" approach.

For completeness, write_csv() from the readr package is faster and never writes row names

# install.packages('readr', dependencies = TRUE)
library(readr)
write_csv(t, "t.csv")

If you need to write big data out, use fwrite() from the data.table package. It's much faster than both write.csv and write_csv

# install.packages('data.table')
library(data.table)
fwrite(t, "t.csv")

Below is a benchmark that Edouard published on his site

microbenchmark(write.csv(data, "baseR_file.csv", row.names = F),
               write_csv(data, "readr_file.csv"),
               fwrite(data, "datatable_file.csv"),
               times = 10, unit = "s")

## Unit: seconds
##                                              expr        min         lq       mean     median         uq        max neval
##  write.csv(data, "baseR_file.csv", row.names = F) 13.8066424 13.8248250 13.9118324 13.8776993 13.9269675 14.3241311    10
##                 write_csv(data, "readr_file.csv")  3.6742610  3.7999409  3.8572456  3.8690681  3.8991995  4.0637453    10
##                fwrite(data, "datatable_file.csv")  0.3976728  0.4014872  0.4097876  0.4061506  0.4159007  0.4355469    10

That will be (for you very specific example)

ActiveWorkbook.worksheets("Sheet2").cells(aRow,aCol).Value=someval

OR

someVal=ActiveWorkbook.worksheets("Sheet2").cells(aRow,aCol).Value

So get a F1 click and read about Worksheets collection, which contains Worksheet objects, which in turn has a Cells collection, holding Cell objects...

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.

1. [ChildActionOnly] allowing restricted access via code in View

2. State Information implementation for specific page URL. Example: Payment Page URL (paying only once) razor syntax allows to call specific actions conditional

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

public abstract class AsyncTaskWithTimer<Params, Progress, Result> extends
    AsyncTask<Params, Progress, Result> {

private static final int HTTP_REQUEST_TIMEOUT = 30000;

@Override
protected Result doInBackground(Params... params) {
    createTimeoutListener();
    return doInBackgroundImpl(params);
}

private void createTimeoutListener() {
    Thread timeout = new Thread() {
        public void run() {
            Looper.prepare();

            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    if (AsyncTaskWithTimer.this != null
                            && AsyncTaskWithTimer.this.getStatus() != Status.FINISHED)
                        AsyncTaskWithTimer.this.cancel(true);
                    handler.removeCallbacks(this);
                    Looper.myLooper().quit();
                }
            }, HTTP_REQUEST_TIMEOUT);

            Looper.loop();
        }
    };
    timeout.start();
}

abstract protected Result doInBackgroundImpl(Params... params);
}

A Sample for this

public class AsyncTaskWithTimerSample extends AsyncTaskWithTimer<Void, Void, Void> {

    @Override
    protected void onCancelled(Void void) {
        Log.d(TAG, "Async Task onCancelled With Result");
        super.onCancelled(result);
    }

    @Override
    protected void onCancelled() {
        Log.d(TAG, "Async Task onCancelled");
        super.onCancelled();
    }

    @Override
    protected Void doInBackgroundImpl(Void... params) {
        // Do background work
        return null;
    };
 }

Instead of reinventing the wheel go with envsubst Can be used in almost any scenario, for instance building configuration files from environment variables in docker containers.

If on mac make sure you have homebrew then link it from gettext:

brew install gettext
brew link --force gettext

./template.cfg

# We put env variables into placeholders here
this_variable_1 = ${SOME_VARIABLE_1}
this_variable_2 = ${SOME_VARIABLE_2}

./.env:

SOME_VARIABLE_1=value_1
SOME_VARIABLE_2=value_2

./configure.sh

#!/bin/bash
cat template.cfg | envsubst > whatever.cfg

Now just use it:

# make script executable
chmod +x ./configure.sh
# source your variables
. .env
# export your variables
# In practice you may not have to manually export variables 
# if your solution depends on tools that utilise .env file 
# automatically like pipenv etc. 
export SOME_VARIABLE_1 SOME_VARIABLE_2
# Create your config file
./configure.sh

The below one worked for me in MySQL:

SELECT DISTINCT CITY FROM STATION WHERE SUBSTR(CITY,1,1) IN ('A','E','I','O','U') AND SUBSTR(CITY,-1,1) in ('A','E','I','O','U');

the following should do:

svn status | grep ". L" | sed 's/.* (.*)$/\1/' | awk '{print length($1),$1}' | sort -nr | awk '{print "pushd " $2 "; svn cleanup ; popd"}' | sh

You can use ARG - see https://docs.docker.com/engine/reference/builder/#arg

The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag. If a user specifies a build argument that was not defined in the Dockerfile, the build outputs an error.

my.data.frame <- subset(data , V1 > 2 | V2 < 4)

An alternative solution that mimics the behavior of this function and would be more appropriate for inclusion within a function body:

new.data <- data[ which( data$V1 > 2 | data$V2 < 4) , ]

Some people criticize the use of which as not needed, but it does prevent the NA values from throwing back unwanted results. The equivalent (.i.e not returning NA-rows for any NA's in V1 or V2) to the two options demonstrated above without the which would be:

 new.data <- data[ !is.na(data$V1 | data$V2) & ( data$V1 > 2 | data$V2 < 4)  , ]

Note: I want to thank the anonymous contributor that attempted to fix the error in the code immediately above, a fix that got rejected by the moderators. There was actually an additional error that I noticed when I was correcting the first one. The conditional clause that checks for NA values needs to be first if it is to be handled as I intended, since ...

> NA & 1
[1] NA
> 0 & NA
[1] FALSE

Order of arguments may matter when using '&".

An easy way to do with HTML+CSS:

TEXT A <b>text b</b>

<h1>text b</h1>

<style>
    h1 { /* the css style */}
    h1:before {content:"text A (p.e.first word) with different style";    
    display:"inline";/* the different css style */}
</style>

I think the simplest way is:

Create a new list and add unique item.

Example:

        class MyList{
    int id;
    string date;
    string email;
    }
    
    List<MyList> ml = new Mylist();

ml.Add(new MyList(){
id = 1;
date = "2020/09/06";
email = "zarezadeh@gmailcom"
});

ml.Add(new MyList(){
id = 2;
date = "2020/09/01";
email = "zarezadeh@gmailcom"
});

 List<MyList> New_ml = new Mylist();

foreach (var item in ml)
                {
                    if (New_ml.Where(w => w.email == item.email).SingleOrDefault() == null)
                    {
                        New_ml.Add(new MyList()
                        {
                          id = item.id,
     date = item.date,
               email = item.email
                        });
                    }
                }

Because you can only deactivate the active environment, so conda deactivate does not need nor accept arguments. The error message is very explicit here.

Just call conda deactivate https://github.com/conda/conda/issues/7296#issuecomment-389504269

Use .closest() with a selector:

var $div = $('#divid').closest('div[class^="div-a"]');

select getdate()

I would say that first and foremost: be consistent.

I reckon you are almost there with the conventions that you have outlined in your question. A couple of comments though:

Points 1 and 2 are good I reckon.

Point 3 - sadly this is not always possible. Think about how you would cope with a single table foo_bar that has columns foo_id and another_foo_id both of which reference the foo table foo_id column. You might want to consider how to deal with this. This is a bit of a corner case though!

Point 4 - Similar to Point 3. You may want to introduce a number at the end of the foreign key name to cater for having more than one referencing column.

Point 5 - I would avoid this. It provides you with little and will become a headache when you want to add or remove columns from a table at a later date.

Some other points are:

Index Naming Conventions

You may wish to introduce a naming convention for indexes - this will be a great help for any database metadata work that you might want to carry out. For example you might just want to call an index foo_bar_idx1 or foo_idx1 - totally up to you but worth considering.

Singular vs Plural Column Names

It might be a good idea to address the thorny issue of plural vs single in your column names as well as your table name(s). This subject often causes big debates in the DB community. I would stick with singular forms for both table names and columns. There. I've said it.

The main thing here is of course consistency!

var arrofobject = [{"id":"197","category":"Damskie"},{"id":"198","category":"M\u0119skie"}];

$.each(arrofobject, function(index, val) {
    console.log(val.category);
});

If you're running ubuntu container directly without a local Dockerfile you can ssh into the container and enable root control by entering su then apt-get install -y wget

It's possible that .NET Core is installed but not added to the PATH variable for your operating system or user profile. Running the dotnet commands may not work. As an alternative, you can check that the .NET Core install folders exist.

It's installed to a standard folder if you didn't change it during the instillation

• dotnet executable C:\program files\dotnet\dotnet.exe

• .NET SDK C:\program files\dotnet\sdk\{version}\

• .NET Runtime C:\program files\dotnet\shared\{runtime-type}\{version}\

For more details check How to check that .NET Core is already installed page at .NET documentation

Just to add to the above..you can use the alpha channel with the new color attributes eg. rgba(0,0,0,0) ok so this is black but with zero opacity so as a parent it will not affect the child. This only works on Chrome, FF, Safari and....I thin O.

convert your hex colours to RGBA

I've had the same issue today and I've not done any intermediate merges so from your opening post only #1 might apply - however i have made commits both from an svn client in ubuntu as well as tortoisesvn in windows. Luckily in my case no changes to the trunk were made so I could just replace the trunk with the branch. Possibly different svn versions then? That's quite worrying.

If you use the svn move / copy /delete functions though no history is lost in my case - i svn moved the trunk and then svn moved the branch to trunk.

"You must specify a region" is a not an ECS specific error, it can happen with any AWS API/CLI/SDK command.

For the CLI, either set the AWS_DEFAULT_REGION environment variable. e.g.

export AWS_DEFAULT_REGION=us-east-1

or add it into the command (you will need this every time you use a region-specific command)

AWS_DEFAULT_REGION=us-east-1 aws ecs list-container-instances --cluster default

or set it in the CLI configuration file: ~/.aws/config

[default]
region=us-east-1

or pass/override it with the CLI call:

aws ecs list-container-instances --cluster default --region us-east-1

And to complement Rich's recursive answer, a non-recursive method.

Public Sub NonRecursiveMethod()
    Dim fso, oFolder, oSubfolder, oFile, queue As Collection

    Set fso = CreateObject("Scripting.FileSystemObject")
    Set queue = New Collection
    queue.Add fso.GetFolder("your folder path variable") 'obviously replace

    Do While queue.Count > 0
        Set oFolder = queue(1)
        queue.Remove 1 'dequeue
        '...insert any folder processing code here...
        For Each oSubfolder In oFolder.SubFolders
            queue.Add oSubfolder 'enqueue
        Next oSubfolder
        For Each oFile In oFolder.Files
            '...insert any file processing code here...
        Next oFile
    Loop

End Sub

You can use a queue for FIFO behaviour (shown above), or you can use a stack for LIFO behaviour which would process in the same order as a recursive approach (replace Set oFolder = queue(1) with Set oFolder = queue(queue.Count) and replace queue.Remove(1) with queue.Remove(queue.Count), and probably rename the variable...)

Just a hint if you have long filenames in utf-8: by default they will be shortened to 20 bytes, so it may happen that the last character might be "cut in half" and therefore unrecognized properly. Then you may want to set the following:

IndexOptions Charset=UTF-8 NameWidth=*

NameWidth setting will prevent shortening your file names, making them properly displayed and readable.

As other users already mentioned, this should be added either in httpd.conf or apache2.conf (if you do have admin rights) or in .htaccess (if you don't).

There are very few cases where you want to use except:. Doing this captures any exception, which can be hard to debug, and it captures exceptions including SystemExit and KeyboardInterupt, which can make your program annoying to use..

At the very simplest, you would catch urllib2.URLError:

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    raise MyException("There was an error: %r" % e)

The following should capture the specific error raised when the connection times out:

import urllib2
import socket

class MyException(Exception):
    pass

try:
    urllib2.urlopen("http://example.com", timeout = 1)
except urllib2.URLError, e:
    # For Python 2.6
    if isinstance(e.reason, socket.timeout):
        raise MyException("There was an error: %r" % e)
    else:
        # reraise the original error
        raise
except socket.timeout, e:
    # For Python 2.7
    raise MyException("There was an error: %r" % e)

#!/bin/ruby

def div_by_3(i)
  i.div 3        # always return int http://www.ruby-doc.org/core-1.9.3/Numeric.html#method-i-div
end

Simply you can use $state.transitionTo instead of $state.go . $state.go calls $state.transitionTo internally but automatically sets options to { location: true, inherit: true, relative: $state.$current, notify: true } . You can call $state.transitionTo and set notify: false . For example:

$state.go('.detail', {id: newId}) 

can be replaced by

$state.transitionTo('.detail', {id: newId}, {
    location: true,
    inherit: true,
    relative: $state.$current,
    notify: false
})

Edit: As suggested by fracz it can simply be:

$state.go('.detail', {id: newId}, {notify: false}) 

On Ubuntu; using mkvirtualenv -p python3 env_name loads the virtualenv with python3.

Inside the env, use python --version to verify.

get GTK3 version:

dpkg -s libgtk-3-0|grep '^Version'

or just version number

dpkg -s libgtk-3-0|grep '^Version' | cut -d' ' -f2-

My fix was suprisingly simple and another one of those obvious when you realise what you've done. I was manually building the configuration using .NET Core/Standard in the following fashion:

var configurationBuilder = new ConfigurationBuilder();
var root = configurationBuilder.Build(); 

and had forgotten to include the appsettings.json file that had my configuration settings in it

configurationBuilder.AddJsonFile("appsettings.json", false);

Once added, all started working once more.

use inline-block instead of inline. Read more information here about the difference between inline and inline-block.

.inline { 
display: inline-block; 
border: 1px solid red; 
margin:10px;
}

It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.

Using it in the meta tag is fine, but only for pages that include that meta tag.

Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.

open command prompt and run the following commands (assuming python 2.7):

cd c:\Python27\scripts\

For those late-comers that are looking for a solution that "just works":

#include <utility>
#include <iostream>

template< typename T >
class Y {

    template< bool cond, typename U >
    using resolvedType  = typename std::enable_if< cond, U >::type; 

    public:
        template< typename U = T > 
        resolvedType< true, U > foo() {
            return 11;
        }
        template< typename U = T >
        resolvedType< false, U > foo() {
            return 12;
        }

};


int main() {
    Y< double > y;

    std::cout << y.foo() << std::endl;
}

Compile with:

g++ -std=gnu++14 test.cpp 

Running gives:

We encountered this error after an upgrade from 2008 to 2014 SQL Server where our some of our previous connection strings for local development had a Data Source=./ like this

        <add name="MyLocalDatabase" connectionString="Data Source=./;Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

Changing that from ./ to either (local) or localhost fixed the problem.

<add name="MyLocalDatabase" connectionString="Data Source=(local);Initial Catalog=SomeCatalog;Integrated Security=SSPI;Application Name=MyApplication;"/>

You can use one of this two options:

1) Add data-dismiss to the submit button i.e.

<button type="submit" class="btn btn-success" data-dismiss="modal"><i class="glyphicon glyphicon-ok"></i> Save</button>

2) Do it in JS like

$('#frmStudent').submit(function() {
    $('#StudentModal').modal('hide');
});

For me, the "Copy Local = true" solution was insufficient because my Website's project references did not include all the dlls that were missing. As Scott mentions in his post, I also needed to get additional dlls from the following folder on my development box: C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies. The error message informed me which dll was missing (System.Web.Infrastructure, System.Web.Razor, etc.) I continued to add each missing dll, one by one, until it worked.

Get from Yahoo a JSON or XML that you can parse from a REST query.

You can exchange from any to any currency and even get the date and time of the query using the YQL (Yahoo Query Language).

I had this error too, my problem was in some part of code I didn't close file descriptor and in other part, I tried to open that file!! use close(fd) system call after you finished working on a file.

Move import sys outside of the try-except block:

import sys
try:
    # ...
except ImportError:
    # ...

If any of the imports before the import sys line fails, the rest of the block is not executed, and sys is never imported. Instead, execution jumps to the exception handling block, where you then try to access a non-existing name.

sys is a built-in module anyway, it is always present as it holds the data structures to track imports; if importing sys fails, you have bigger problems on your hand (as that would indicate that all module importing is broken).

=> "/images/my_image.png"

Try passing in a Date object instead. I can't see why it doesn't work in the format you have entered:

<script type="text/javascript">
$(function() {               
    $("#birthdate" ).datepicker({
        changeMonth: true,
        changeYear: true,
        yearRange: '1920:2010',
        dateFormat : 'dd-mm-yy',
        defaultDate: new Date(1985, 00, 01)
    });
});
</script>

http://api.jqueryui.com/datepicker/#option-defaultDate

Specify either an actual date via a Date object or as a string in the current dateFormat, or a number of days from today (e.g. +7) or a string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '+1m +7d'), or null for today.

As long as pip lives within the scripts folder you can run

python -m pip ....

This will tell python to get pip from inside the scripts folder. This is also a good way to have both python2.7 and pyhton3.5 on you computer and have them in different locations. I currently have both python2 and pyhton3 installed on windows. When I type python it defaults to python2. But if I type python3 I can use python3. (I also had to change the python.exe file for python3 to "python3.exe")If I need to install flask for python 2 I can run

python -m pip install flask

and it will be installed in the pyhton2 folder, but if I need flask for python 3 I run:

python3 -m pip install flask

and I now have it in the python3 folder

Tab is [HT], or character number 9, in the unicode library.

Only need:

var place = autocomplete.getPlace();
// get lat
var lat = place.geometry.location.lat();
// get lng
var lng = place.geometry.location.lng();

In addition to psparrow's answer if you need to add an index to your temporary table do:

CREATE TEMPORARY TABLE IF NOT EXISTS 
  temp_table ( INDEX(col_2) ) 
ENGINE=MyISAM 
AS (
  SELECT col_1, coll_2, coll_3
  FROM mytable
)

It also works with PRIMARY KEY

After testing all mentioned suggestions, nothing worked. I made this code. It works, but is not beautiful

public void click(WebElement element) {
    //https://code.google.com/p/selenium/issues/detail?id=2766 (fix)
    while(true){
        try{
            element.click();
            break;
        }catch (Throwable e){
            try {
                Thread.sleep(200);
            } catch (InterruptedException e1) {
                e1.printStackTrace();
            }
        }
    }
}

public void click(String css) {
    //https://code.google.com/p/selenium/issues/detail?id=2766 (fix)
    while(true){
        try{
            driver.findElement(By.cssSelector(css)).click();
            break;
        }catch (Throwable e){
            try {
                Thread.sleep(200);
            } catch (InterruptedException e1) {
                e1.printStackTrace();
            }
        }
    }
}

Using .net core jwt packages, the Claims are available:

[Route("api/[controller]")]
[ApiController]
[Authorize(Policy = "Bearer")]
public class AbstractController: ControllerBase
{
    protected string UserId()
    {
        var principal = HttpContext.User;
        if (principal?.Claims != null)
        {
            foreach (var claim in principal.Claims)
            {
               log.Debug($"CLAIM TYPE: {claim.Type}; CLAIM VALUE: {claim.Value}");
            }

        }
        return principal?.Claims?.SingleOrDefault(p => p.Type == "username")?.Value;
    }
}

Have you tried to use TimeZone.getDefault():

Most applications will use TimeZone.getDefault() which returns a TimeZone based on the time zone where the program is running.

GCC adds C++ multiline raw string literals as a C extension

C++11 has raw string literals as mentioned at: https://stackoverflow.com/a/44337236/895245

However, GCC also adds them as a C extension, you just have to use -std=gnu99 instead of -std=c99. E.g.:

main.c

#include <assert.h>
#include <string.h>

int main(void) {
    assert(strcmp(R"(
a
b
)", "\na\nb\n") == 0);
}

Compile and run:

gcc -o main -pedantic -std=gnu99 -Wall -Wextra main.c
./main

This can be used for example to insert multiline inline assembly into C code: How to write multiline inline assembly code in GCC C++?

Now you just have to lay back, and wait for it to be standardized on C20XY.

C++ was asked at: C++ multiline string literal

Tested on Ubuntu 16.04, GCC 6.4.0, binutils 2.26.1.

Since the introduction of interaction media features you simply can do:

if(window.matchMedia("(pointer: coarse)").matches) {
    // touchscreen
}

https://www.w3.org/TR/mediaqueries-4/#descdef-media-any-pointer

Update (due to comments): The above solution is to detect if a "coarse pointer" - usually a touch screen - is the primary input device. In case you want to dectect if a device with e.g. a mouse also has a touch screen you may use any-pointer: coarse instead.

For more information have a look here: Detecting that the browser has no mouse and is touch-only

You can do the same thing with the connection opened just once. Something like this.

for(int i=0; i< dataGridView1.Rows.Count;i++)
  {
    string StrQuery= @"INSERT INTO tableName VALUES (" + dataGridView1.Rows[i].Cells["ColumnName"].Value +", " + dataGridView1.Rows[i].Cells["ColumnName"].Value +");";

  try
  {
      SqlConnection conn = new SqlConnection();
      conn.Open();

          using (SqlCommand comm = new SqlCommand(StrQuery, conn))
          {
              comm.ExecuteNonQuery();
          }
      conn.Close();

  }

Also, depending on your specific scenario you may want to look into binding the grid to the database. That would reduce the amount of manual work greatly: http://www.switchonthecode.com/tutorials/csharp-tutorial-binding-a-datagridview-to-a-database

if the type is list, use len(list) and len(list[0]) to get the row and column.

l = [[1,2,3,4], [0,1,3,4]]

len(l) will be 2 len(l[0]) will be 4

A dirty trick I somtimes use, is hiding variables in the 'name' attribute (that I normally don't use for other purposes):

select onFocus=(this.name=this.value) onChange=someFunction(this.name,this.value)><option...

Somewhat unexpectedly, both the old and the new value is then submitted to someFunction(oldValue,newValue)

HTTP Error 404.15 - Not Found The request filtering module is configured to deny a request where the query string is too long.

To resolve this problem, check in the source code whether the Form tag has a property method is get/set state.

If so, the method property should be removed.

For spring boot framework version 2.0.4.RELEASE+. Add this line to application.properties

server.servlet.context-path=/api

Assigning Comparison to property value

JavaScript

You could assign the comparison of the property to "1"

obj["isChecked"] = (obj["isChecked"]==="1");

This only evaluates for a String value of "1" though. Other variables evaulate to false like an actual typeof number would be false. (i.e. obj["isChecked"]=1)

If you wanted to be indiscrimate about "1" or 1, you could use:

obj["isChecked"] = (obj["isChecked"]=="1");

Example Outputs

console.log(obj["isChecked"]==="1"); // true
console.log(obj["isChecked"]===1); // false
console.log(obj["isChecked"]==1); // true
console.log(obj["isChecked"]==="0"); // false
console.log(obj["isChecked"]==="Elephant"); // false

PHP

Same concept in PHP

$obj["isChecked"] = ($obj["isChecked"] == "1");

The same operator limitations as stated above for JavaScript apply.

Double Not

The 'double not' also works. It's confusing when people first read it but it works in both languages for integer/number type values. It however does not work in JavaScript for string type values as they always evaluate to true:

JavaScript

!!"1"; //true
!!"0"; //true
!!1; //true
!!0; //false
!!parseInt("0",10); // false

PHP

echo !!"1"; //true
echo !!"0"; //false
echo !!1; //true
echo !!0; //false

The scope <scope>provided</scope> gives you an opportunity to tell that the jar would be available at runtime, so do not bundle it. It does not mean that you do not need it at compile time, hence maven would try to download that.

Now I think, the below maven artifact do not exist at all. I tries searching google, but not able to find. Hence you are getting this issue.

Change groupId to <groupId>net.sourceforge.ant4x</groupId> to get the latest jar.

<dependency>
  <groupId>net.sourceforge.ant4x</groupId>
  <artifactId>ant4x</artifactId>
  <version>${net.sourceforge.ant4x-version}</version>
  <scope>provided</scope>
</dependency>

Another solution for this problem is:

1. Run your own maven repo.
2. download the jar
3. Install the jar into the repository.
4. Add a code in your pom.xml something like:

Where http://localhost/repo is your local repo URL:

<repositories>
    <repository>
        <id>wmc-central</id>
        <url>http://localhost/repo</url>
    </repository>
    <-- Other repository config ... -->
</repositories>

If you want the output to print to the terminal it is best to use Rscript

Rscript a.R

Note that when using R CMD BATCH a.R that instead of redirecting output to standard out and displaying on the terminal a new file called a.Rout will be created.

R CMD BATCH a.R
# Check the output
cat a.Rout

One other thing to note about using Rscript is that it doesn't load the methods package by default which can cause confusion. So if you're relying on anything that methods provides you'll want to load it explicitly in your script.

If you really want to use the ./a.R way of calling the script you could add an appropriate #! to the top of the script

#!/usr/bin/env Rscript
sayHello <- function(){
   print('hello')
}

sayHello()

I will also note that if you're running on a *unix system there is the useful littler package which provides easy command line piping to R. It may be necessary to use littler to run shiny apps via a script? Further details can be found in this question.

The oddly named "blame" command does this. If you use Tortoise, it gives you a "from revision" dialog, then a file listing with a line by line indicator of Revision number and author next to it.

If you right click on the revision info, you can bring up a "Show log" dialog that gives full checkin information, along with other files that were part of the checkin.

From ioS 7 onwards, there are newer ways for apps to run in background. Apple now recognizes that apps have to constantly download and process data constantly.

Here is the new list of all the apps which can run in background.

1. Apps that play audible content to the user while in the background, such as a music player app
2. Apps that record audio content while in the background.
3. Apps that keep users informed of their location at all times, such as a navigation app
4. Apps that support Voice over Internet Protocol (VoIP)
5. Apps that need to download and process new content regularly
6. Apps that receive regular updates from external accessories

You can declare app's supported background tasks in Info.plist using X Code 5+. For eg. adding UIBackgroundModes key to your app’s Info.plist file and adding a value of 'fetch' to the array allows your app to regularly download and processes small amounts of content from the network. You can do the same in the 'capabilities' tab of Application properties in XCode 5 (attaching a snapshot)

You can find more about this in Apple documentation

It's the year 2015. The correct answer to this question at this point is to use CSS white-space: pre-line or white-space: pre-wrap. Clean and elegant. The lowest version of IE that supports the pair is 8.

https://css-tricks.com/almanac/properties/w/whitespace/

P.S. Until CSS3 become common you'd probably need to manually trim off initial and/or trailing white-spaces.

You should use the overloaded sort(peps, new People()) method

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

public class Test 
{
    public static void main(String[] args) 
    {
        List<People> peps = new ArrayList<>();

        peps.add(new People(123, "M", 14.25));
        peps.add(new People(234, "M", 6.21));
        peps.add(new People(362, "F", 9.23));
        peps.add(new People(111, "M", 65.99));
        peps.add(new People(535, "F", 9.23));

        Collections.sort(peps, new People().new ComparatorId());

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

class People
{
       private int id;
       private String info;
       private double price;

       public People()
       {

       }

       public People(int newid, String newinfo, double newprice) {
           setid(newid);
           setinfo(newinfo);
           setprice(newprice);
       }

       public int getid() {
           return id;
       }

       public void setid(int id) {
           this.id = id;
       }

       public String getinfo() {
           return info;
       }

       public void setinfo(String info) {
           this.info = info;
       }

       public double getprice() {
           return price;
       }

       public void setprice(double price) {
           this.price = price;
       }

       class ComparatorId implements Comparator<People>
       {

        @Override
        public int compare(People obj1, People obj2) {
               Integer p1 = obj1.getid();
               Integer p2 = obj2.getid();

               if (p1 > p2) {
                   return 1;
               } else if (p1 < p2){
                   return -1;
               } else {
                   return 0;
               }
            }
       }
    }

You should do like this:

@Html.DropDownListFor(m => m.ContribType, 
                new SelectList(Model.ContribTypeOptions, 
                               "ContribId", "Value"))

Where:

m => m.ContribType

is a property where the result value will be.

You need to set this permission in your manifest.xml file

android.permission.WRITE_EXTERNAL_STORAGE

Use DateTime::createFromFormat

$date = date_create_from_format('d/m/Y:H:i:s', $s);
$date->getTimestamp();

set "CMD=C:\Program Files (x86)\PDFtk\bin\pdftk"
echo cmd /K ""%CMD%" %D% output trimmed.pdf"
start cmd /K ""%CMD%" %D% output trimmed.pdf"

this worked for me in a batch file

Consider this example:

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|")));
    // output : [Real, How, To]
  }
}

The result does not include the empty strings between the "|" separator. To keep the empty strings :

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|", -1)));
    // output : [Real, How, To, , , ]
  }
}

Since hashes aren't inherently ordered, there isn't a notion of appending. Ruby hashes since 1.9 maintain insertion order, however. Here are the ways to add new key/value pairs.

The simplest solution is

h[:key] = "bar"

If you want a method, use store:

h.store(:key, "bar")

If you really, really want to use a "shovel" operator (<<), it is actually appending to the value of the hash as an array, and you must specify the key:

h[:key] << "bar"

The above only works when the key exists. To append a new key, you have to initialize the hash with a default value, which you can do like this:

h = Hash.new {|h, k| h[k] = ''}
h[:key] << "bar"

You may be tempted to monkey patch Hash to include a shovel operator that works in the way you've written:

class Hash
  def <<(k,v)
    self.store(k,v)
  end
end

However, this doesn't inherit the "syntactic sugar" applied to the shovel operator in other contexts:

h << :key, "bar" #doesn't work
h.<< :key, "bar" #works

I think this could help you:

let timeNow = time(nil)
let aStr = String(format: "%@%x", "timeNow in hex: ", timeNow)
print(aStr)

Example result:

timeNow in hex: 5cdc9c8d

Try with the relative path using *

  @ContextConfiguration(locations = {
"classpath*:spring/applicationContext.xml",
"classpath*:spring/applicationContext-jpa.xml",
"classpath*:spring/applicationContext-security.xml" })

If not look if your xml are really on resources/spring/.

Finally try just on without location

 @ContextConfiguration({"classpath*:spring/applicationContext.xml"})

The other error that you´re showing is because you have this tag duplicated on applicationContext.xml and applicationContext-security.xml

 Duplicate <global-method-security>

try this, hope it will help you to get the current location, every time the location changes.

public class MyClass implements LocationListener {
    double currentLatitude, currentLongitude;

    public void onLocationChanged(Location location) {
        currentLatitude = location.getLatitude();
        currentLongitude = location.getLongitude();
    }
}

Based on my knowledge, if you put your image folder in your public folder, you can just do the following:

   <div :style="{backgroundImage: `url(${project.imagePath})`}"></div>

If you put your images in the src/assets/, you need to use require. Like this:

   <div :style="{backgroundImage: 'url('+require('@/assets/'+project.image)+')'}">. 
   </div>

One important thing is that you cannot use an expression that contains the full URL like this project.image = '@/assets/image.png'. You need to hardcode the '@assets/' part. That was what I've found. I think the reason is that in Webpack, a context is created if your require contains expressions, so the exact module is not known on compile time. Instead, it will search for everything in the @/assets folder. More info could be found here. Here is another doc explains how the Vue loader treats the link in single file components.

We can use case statement Like this

select Name,EmailId,gender=case 
when gender='M' then 'F'
when gender='F' then 'M'
end
 from [dbo].[Employees]

WE can also it as follow.

select Name,EmailId,case gender
when 'M' then 'F'
when 'F' then 'M'
end
 from [dbo].[Employees]

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

If you want to first take mean on the combination of ['cluster', 'org'] and then take mean on cluster groups, you can use:

In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
            .groupby('cluster')['time'].mean())
Out[59]:
cluster
1          15
2          54
3           6
Name: time, dtype: int64

If you want the mean of cluster groups only, then you can use:

In [58]: df.groupby(['cluster']).mean()
Out[58]:
              time
cluster
1        12.333333
2        54.000000
3         6.000000

You can also use groupby on ['cluster', 'org'] and then use mean():

In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
               time
cluster org
1       a    438886
        c        23
2       d      9874
        h        34
3       w         6

This may or may not work for your purposes, but you can extend jScrollPane to fire other functionality before it does its scrolling. I've only just tested this a little bit, but I can confirm that you can jump in and prevent the scrolling entirely. All I did was:

• Download the demo zip: http://github.com/vitch/jScrollPane/archives/master
• Open the "Events" demo (events.html)
• Edit it to use the non-minified script source: <script type="text/javascript" src="script/jquery.jscrollpane.js"></script>
• Within jquery.jscrollpane.js, insert a "return;" at line 666 (auspicious line number! but in case your version differs slightly, this is the first line of the positionDragY(destY, animate) function

Fire up events.html, and you'll see a normally scrolling box which due to your coding intervention won't scroll.

You can control the entire browser's scrollbars this way (see fullpage_scroll.html).

So, presumably the next step is to add a call to some other function that goes off and does your anchoring magic, then decides whether to continue with the scroll or not. You've also got API calls to set scrollTop and scrollLeft.

If you want more help, post where you get up to!

Hope this has helped.

you use that code

ImageView[] ivCard = new ImageView[1];

@override    
protected void onCreate(Bundle savedInstanceState)  

ivCard[0]=(ImageView)findViewById(R.id.imageView1);

When you allow the 9000 port to firewall on your desired operating System the following error "ERROR: Sonar server 'http://localhost:9000' can not be reached" will remove successfully.In ubuntu it is just like as by typing the following command in terminal "sudo ufw allow 9000/tcp" this error will removed from the Jenkins server by clicking on build now in jenkins.

In order to see the changes that have been staged already, you can pass the -–staged option to git diff (in pre-1.6 versions of Git, use –-cached).

git diff --staged
git diff --cached

Your sprite is created mid way through the playerSprite function... it also goes out of scope and ceases to exist at the end of that same function. The sprite must be created where you can pass it to playerSprite to initialize it and also where you can pass it to your draw function.

Perhaps declare it above your first while?

I believe that the body height being returned is the visible height. If you need the total page height, you could wrap your div tags in a containing div and get the height of that.

Such a headache and so less consideration to other cultures for nothing...

here it is folks:

let floatPrice = parseFloat(price.replace(/(,|\.)([0-9]{3})/g,'$2').replace(/(,|\.)/,'.'));

as simple as that.

What I'd do is:

1. Extract the text and value of each <option> into an array of objects;
2. Sort the array;
3. Update the <option> elements with the array contents in order.

To do that with jQuery, you could do this:

var options = $('select.whatever option');
var arr = options.map(function(_, o) { return { t: $(o).text(), v: o.value }; }).get();
arr.sort(function(o1, o2) { return o1.t > o2.t ? 1 : o1.t < o2.t ? -1 : 0; });
options.each(function(i, o) {
  o.value = arr[i].v;
  $(o).text(arr[i].t);
});

Here is a working jsfiddle.

edit — If you want to sort such that you ignore alphabetic case, you can use the JavaScript .toUpperCase() or .toLowerCase() functions before comparing:

arr.sort(function(o1, o2) {
  var t1 = o1.t.toLowerCase(), t2 = o2.t.toLowerCase();

  return t1 > t2 ? 1 : t1 < t2 ? -1 : 0;
});

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

To write text in a file in the flask can be used:

filehandle = open("text.txt", "w")
filebuffer = ["hi","welcome","yes yes welcome"]
filehandle.writelines(filebuffer)
filehandle.close()

Use wildcards:

cp /home/ankur/folder/* /home/ankur/dest

If you don't want to copy all the files, you can use braces to select files:

cp /home/ankur/folder/{file{1,2},xyz,abc} /home/ankur/dest

This will copy file1, file2, xyz, and abc.

You should read the sections of the bash man page on Brace Expansion and Pathname Expansion for all the ways you can simplify this.

Another thing you can do is cd /home/ankur/folder. Then you can type just the filenames rather than the full pathnames, and you can use filename completion by typing Tab.

The quickest way is to switch default branch from master to another and you can remove master branch from the web interface.

In the css rule you have to add the extension of the file. This example with the deepest support possible:

@font-face {
  font-family: 'MyWebFont';
  src: url('webfont.eot'); /* IE9 Compat Modes */
  src: url('webfont.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
       url('webfont.woff2') format('woff2'), /* Super Modern Browsers */
       url('webfont.woff') format('woff'), /* Pretty Modern Browsers */
       url('webfont.ttf')  format('truetype'), /* Safari, Android, iOS */
       url('webfont.svg#svgFontName') format('svg'); /* Legacy iOS */
}

EDIT:

"Failed to decode downloaded font" means the font is corrupt, or is incomplete (missing metrics, necessary tables, naming records, a million possible things).

Sometimes this problem is caused by the font itself. Google font provides the correct font you need but if font face is necessary i use Transfonter to generate all font format.

Sometimes is the FTP client that corrupt the file (not in this case because is on local pc). Be sure to transfer file in binary and not in ASCII.

At work we only have Excel 2003 available and these two formulas seem to work perfectly for me:

=(ROUND(SUM(B3/C3),0))&":1"

or

=B3/GCD(B3,C3)&":"&C3/GCD(B3,C3)

 echo "<a href='#' style = \"font-color: #ff0000;\"> Movie List for {$key} 2013 </a>";

Yes, as long as no one is looking over your shoulder at the monitor.

this can be achieved using below...

 List<String> unavailable = list1.stream()
                            .filter(e -> !list2.contains(e))
                            .collect(Collectors.toList());

Sometimes I use a prefixes for my keys. For example:

var pre = 'foo',
    key = pre + 1234

obj = {};

obj[key] = val;

Now you don't have any problem accessing them.

It is important to notice that in C# the char type is stored as Unicode UTF-16.

From ASCII equivalent integer to char

char c = (char)88;

or

char c = Convert.ToChar(88)

From char to ASCII equivalent integer

int asciiCode = (int)'A';

The literal must be ASCII equivalent. For example:

string str = "X?????????";
Console.WriteLine((int)str[0]);
Console.WriteLine((int)str[1]);

will print

X
3626

Extended ASCII ranges from 0 to 255.

From default UTF-16 literal to char

Using the Symbol

char c = 'X';

Using the Unicode code

char c = '\u0058';

Using the Hexadecimal

char c = '\x0058';

You can ssh directly from the Terminal on Mac, but you need to use a .PEM key rather than the putty .PPK key. You can use PuttyGen on Windows to convert from .PEM to .PPK, I'm not sure about the other way around though.

You can also convert the key using putty for Mac via port or brew:

sudo port install putty

or

brew install putty

This will also install puttygen. To get puttygen to output a .PEM file:

puttygen privatekey.ppk -O private-openssh -o privatekey.pem

Once you have the key, open a terminal window and:

ssh -i privatekey.pem [email protected]

The private key must have tight security settings otherwise SSH complains. Make sure only the user can read the key.

chmod go-rw privatekey.pem

UPDATE: installation without root privileges below

I advise you to not install packages manually on ubuntu system if there is already a (semi-official) repository able to solve your problem. Further, use Oracle JDK for development, just to avoid (very sporadic) compatibility issues (i've tried many years ago, it's surely better now).

Add the webupd8 repo to your system:

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update

Install your preferred version of jdk (versions from java-6 to java-9 available):

sudo apt-get install oracle-java8-installer

You can also install multiple version of jdk, mixing openjdk and oracle versions. Then you can use the command update-java-alternatives to switch between installed version:

# list available jdk
update-java-alternatives --list

# use jdk7
sudo update-java-alternatives --set java-7-oracle

# use jdk8
sudo update-java-alternatives --set java-8-oracle

Requirements

If you get add-apt-repository: command not found be sure to have software-properties-common installed:

sudo apt-get install software-properties-common

If you're using an older version Ubuntu:

sudo apt-get install python-software-properties

JDK installation without root privileges

If you haven't administrator rights on your target machine your simplest bet is to use sdkman to install the zulu certified openjdk:

curl -s "https://get.sdkman.io" | bash
source "$HOME/.sdkman/bin/sdkman-init.sh"
sdk install java

NOTE: sdkman allow to install also the official Oracle JDK, although it's not a the default option. View available versions with:

sdk ls java

Install the chosen version with:

sdk install java <version>

For example:

sdk install java 9.0.1-oracle

Glossary of commands

• sudo <command> [command_arguments]: execute a command with the superuser privilege.

• add-apt-repository <PPA_id>: Ubuntu (just like every Debian derivatives and generally speaking every Linux distribution) has a main repository of packages that handle things like package dependencies and updating. In Ubuntu is possible to extend the main repository using a PPA (Personal Package Archive) that usually contains packages not available in the system (just like oracle jdk) or updated versions of available ones (example: LibreOffice 5 in LTS is available only through this PPA).

• apt-get [install|update|upgrade|purge|...]: it's "the" command-line package handler used to manipulate the state of every repository on the system (installing / updating / upgrading can be viewed as an alteration of the repository current state).

In our case: with the command sudo add-apt-repository ppa:webupd8team/java we inform the system that the next repository update must retrieve packages information also from webupd8 repo.

With sudo apt-get update we actually update the system repository (all this operations requires superuser privileges, so we prepend sudo to the commands).

sudo apt-get install oracle-java8-installer

• update-java-alternatives (a specific java version of update-alternatives): in Ubuntu several packages provides the same functionality (browse the internet, compile mails, edit a text file or provides java/javac executables...). To allows the system to choose the user favourites tool given a specific task a mechanism using symlinks under /etc/alternatives/ is used. Try to update the jdk as indicated above (switch between java 7 and java 8) and view how change the output of this command:

  ls -l /etc/alternatives/java*

In our case: sudo update-java-alternatives --set java-8-oracle update symlinks under /etc/alternatives to point to java-8-oracle executables.

Extras:

• man <command>: start using man to read a really well written and detailed help on (almost) every shell command and its options (every command i mention in this little answer has a man page, try man update-java-alternatives).

• apt-cache search <search_key>: query the APT cache to search for a package related with the search_key provided (can be the package name or some word in package description).

• apt-cache show <package>: provides APT information for a specific package (package version, installed or not, description).

One complicated way would be to first commit everything:

git add -u
git commit // creates commit with sha-1 A

Reset back to the original commit but checkout the_one_file from the new commit:

git reset --hard HEAD^
git checkout A path/to/the_one_file

Now you can stash the_one_file:

git stash

Cleanup by saving the committed content in your file system while resetting back to the original commit:

git reset --hard A
git reset --soft HEAD^

Yeah, somewhat awkward...

The URL decoder should only be used for decoding strings from the urls generated by html forms which are in the "application/x-www-form-urlencoded" mime type. This does not support html characters.

After a search I found a Translate class within the HTML Parser library.

t = "your string"

Play with the first N characters of a string with

def firstN(s, n=2):
    return s[:n]

which is by default equivalent to

t[:2]

TypeScript isn't giving you a gun to shoot yourself in the foot with.

The iterator variable is a string because it is a string, full stop. Observe:

var obj = {};
obj['0'] = 'quote zero quote';
obj[0.0] = 'zero point zero';
obj['[object Object]'] = 'literal string "[object Object]"';
obj[<any>obj] = 'this obj'
obj[<any>undefined] = 'undefined';
obj[<any>"undefined"] = 'the literal string "undefined"';

for(var key in obj) {
    console.log('Type: ' + typeof key);
    console.log(key + ' => ' + obj[key]);
}

How many key/value pairs are in obj now? 6, more or less? No, 3, and all of the keys are strings:

Type: string
0 => zero point zero
Type: string
[object Object] => this obj; 
Type: string
undefined => the literal string "undefined" 

You need add charset in the RequestMapping annotation:

@RequestMapping(path = "/account",  produces = "application/json;charset=UTF-8")

thats all.

Use this method:

$_product = wc_get_product( $id );

Official API-docs: wc_get_product

The posts here help me a lot on my way to find a solution for the Uncaught TypeError: Cannot read property 'value' of undefined issue.

There are already here many answers which are correct, but what we don't have here is the combination for 2 answers that i think resolve this issue completely.

function myFunction(field, data){
  if (typeof document.getElementsByName("+field+")[0] != 'undefined'){
  document.getElementsByName("+field+")[0].value=data;
 }
}

The difference is that you make a check(if a property is defined or not) and if the check is true then you can try to assign it a value.

There is usually no difference, as far as page rendering goes. It's a huge facility developer-side, though, when your web project grows bigger.

I make use of both in this fashion:

• .PHP Page doesn't contain view-related code
• .PHTML Page contains little (if any) data logic and the most part of it is presentation-related

mapStateToProps receives the state and props and allows you to extract props from the state to pass to the component.

mapDispatchToProps receives dispatch and props and is meant for you to bind action creators to dispatch so when you execute the resulting function the action gets dispatched.

I find this only saves you from having to do dispatch(actionCreator()) within your component thus making it a bit easier to read.

https://github.com/reactjs/react-redux/blob/master/docs/api.md#arguments

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

Are you trying to pass the command line arguments to the program AS you launch it? I am working on something right now that does exactly this, and it was a lot simpler than I thought. If I go into the command line, and type

C:\folder\app.exe/xC:\folder\file.txt

then my application launches, and creates a file in the specified directory with the specified name.

I wanted to do this through a Powershell script on a remote machine, and figured out that all I needed to do was put

$s = New-PSSession -computername NAME -credential LOGIN
    Invoke-Command -session $s -scriptblock {C:\folder\app.exe /xC:\folder\file.txt}
Remove-PSSession $s

(I have a bunch more similar commands inside the session, this is just the minimum it requires to run) notice the space between the executable, and the command line arguments. It works for me, but I am not sure exactly how your application works, or if that is even how you pass arguments to it.

*I can also have my application push the file back to my own local computer by changing the script-block to

C:\folder\app.exe /x"\\LocalPC\DATA (C)\localfolder\localfile.txt"

You need the quotes if your file-path has a space in it.

EDIT: actually, this brought up some silly problems with Powershell launching the application as a service or something, so I did some searching, and figured out that you can call CMD to execute commands for you on the remote computer. This way, the command is carried out EXACTLY as if you had just typed it into a CMD window on the remote machine. Put the command in the scriptblock into double quotes, and then put a cmd.exe /C before it. like this:

cmd.exe /C "C:\folder\app.exe/xC:\folder\file.txt"

this solved all of the problems that I have been having recently.

EDIT EDIT: Had more problems, and found a much better way to do it.

start-process -filepath C:\folder\app.exe -argumentlist "/xC:\folder\file.txt"

and this doesn't hang up your terminal window waiting for the remote process to end. Just make sure you have a way to terminate the process if it doesn't do that on it's own. (mine doesn't, required the coding of another argument)

I am not sure whether anyone faced issues with getting the whole string "test from adb". Using the escape character in front of the space worked for me.

adb shell am broadcast -a com.whereismywifeserver.intent.TEST --es sms_body "test\ from\ adb" -n com.whereismywifeserver/.IntentReceiver

Default migration generator does not handle default values (column modifiers are supported but do not include default or null), but you could create your own generator.

You can also manually update the migration file prior to running rake db:migrate by adding the options to add_column:

add_column :tweet, :retweets_count, :integer, :null => false, :default => 0

... and read Rails API

You can use the maven.javadoc.skip property to skip execution of the plugin, going by the Mojo's javadoc. You can specify the value as a Maven property:

<properties>
    <maven.javadoc.skip>true</maven.javadoc.skip>
</properties>

or as a command-line argument: -Dmaven.javadoc.skip=true, to skip generation of the Javadocs.

This can be as simple as adding ToList() in your repository. For example:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        // causes an error
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id);
    }
}

Will yield the Db Context disposed error in the calling class but this can be resolved by explicitly exercising the enumeration by adding ToList() on the LINQ operation:

public IEnumerable<MyObject> GetMyObjectsForId(string id)
{
    using (var ctxt = new RcContext())
    {
        return ctxt.MyObjects.Where(x => x.MyObjects.Id == id).ToList();
    }
}

Just listen to the click event as well.

Following from Shiboe's example, here's a jQuery example:

var godzilla = $('#godzilla');
var godzillaBtn = $('#godzilla-btn');

godzillaBtn.on('click', function(){
    godzilla.trigger('click');
});

godzilla.on('change click', function(){

    if (godzilla.val() != '') {
        $('#state').html('You have chosen a Mech!');    
    } else {
        $('#state').html('Choose your Mech!');
    }

});

You can see it in action here: http://jsfiddle.net/T3Vwz

The ActivityResultRegistry is the recommended approach

ComponentActivity now provides an ActivityResultRegistry that lets you handle the startActivityForResult()+onActivityResult() as well as requestPermissions()+onRequestPermissionsResult() flows without overriding methods in your Activity or Fragment, brings increased type safety via ActivityResultContract, and provides hooks for testing these flows.

It is strongly recommended to use the Activity Result APIs introduced in AndroidX Activity 1.2.0-alpha02 and Fragment 1.3.0-alpha02.

Add this to your build.gradle

def activity_version = "1.2.0-beta01"

// Java language implementation
implementation "androidx.activity:activity:$activity_version"
// Kotlin
implementation "androidx.activity:activity-ktx:$activity_version"

How to use the pre-built contract?

This new API has the following pre built functionalities

1. TakeVideo
2. PickContact
3. GetContent
4. GetContents
5. OpenDocument
6. OpenDocuments
7. OpenDocumentTree
8. CreateDocument
9. Dial
10. TakePicture
11. RequestPermission
12. RequestPermissions

An example that uses takePicture contract:

private val takePicture = prepareCall(ActivityResultContracts.TakePicture()) { bitmap: Bitmap? ->
    // Do something with the Bitmap, if present
}
    
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    setContentView(R.layout.activity_main)
    
    button.setOnClickListener { takePicture() }
}

So what’s going on here? Let’s break it down slightly. takePicture is just a callback which returns a nullable Bitmap - whether or not it’s null depends on whether or not the onActivityResult process was successful. prepareCall then registers this call into a new feature on ComponentActivity called the ActivityResultRegistry - we’ll come back to this later. ActivityResultContracts.TakePicture() is one of the built-in helpers which Google have created for us, and finally invoking takePicture actually triggers the Intent in the same way that you would previously with Activity.startActivityForResult(intent, REQUEST_CODE).

How to write a custom contract?

Simple contract that takes an Int as an Input and returns a String that requested Activity returns in the result Intent.

class MyContract : ActivityResultContract<Int, String>() {

    companion object {
        const val ACTION = "com.myapp.action.MY_ACTION"
        const val INPUT_INT = "input_int"
        const val OUTPUT_STRING = "output_string"
    }

    override fun createIntent(input: Int): Intent {
        return Intent(ACTION)
            .apply { putExtra(INPUT_INT, input) }
    }

    override fun parseResult(resultCode: Int, intent: Intent?): String? {
        return when (resultCode) {
            Activity.RESULT_OK -> intent?.getStringExtra(OUTPUT_STRING)
            else -> null
        }
    }
}

class MyActivity : AppCompatActivity() {

    private val myActionCall = prepareCall(MyContract()) { result ->
        Log.i("MyActivity", "Obtained result: $result")
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ...
        button.setOnClickListener {
            myActionCall(500)
        }
    }
}

There is an important difference between the two.

Everything not allocated with new behaves much like value types in C# (and people often say that those objects are allocated on the stack, which is probably the most common/obvious case, but not always true. More precisely, objects allocated without using new have automatic storage duration Everything allocated with new is allocated on the heap, and a pointer to it is returned, exactly like reference types in C#.

Anything allocated on the stack has to have a constant size, determined at compile-time (the compiler has to set the stack pointer correctly, or if the object is a member of another class, it has to adjust the size of that other class). That's why arrays in C# are reference types. They have to be, because with reference types, we can decide at runtime how much memory to ask for. And the same applies here. Only arrays with constant size (a size that can be determined at compile-time) can be allocated with automatic storage duration (on the stack). Dynamically sized arrays have to be allocated on the heap, by calling new.

(And that's where any similarity to C# stops)

Now, anything allocated on the stack has "automatic" storage duration (you can actually declare a variable as auto, but this is the default if no other storage type is specified so the keyword isn't really used in practice, but this is where it comes from)

Automatic storage duration means exactly what it sounds like, the duration of the variable is handled automatically. By contrast, anything allocated on the heap has to be manually deleted by you. Here's an example:

void foo() {
  bar b;
  bar* b2 = new bar();
}

This function creates three values worth considering:

On line 1, it declares a variable b of type bar on the stack (automatic duration).

On line 2, it declares a bar pointer b2 on the stack (automatic duration), and calls new, allocating a bar object on the heap. (dynamic duration)

When the function returns, the following will happen: First, b2 goes out of scope (order of destruction is always opposite of order of construction). But b2 is just a pointer, so nothing happens, the memory it occupies is simply freed. And importantly, the memory it points to (the bar instance on the heap) is NOT touched. Only the pointer is freed, because only the pointer had automatic duration. Second, b goes out of scope, so since it has automatic duration, its destructor is called, and the memory is freed.

And the barinstance on the heap? It's probably still there. No one bothered to delete it, so we've leaked memory.

From this example, we can see that anything with automatic duration is guaranteed to have its destructor called when it goes out of scope. That's useful. But anything allocated on the heap lasts as long as we need it to, and can be dynamically sized, as in the case of arrays. That is also useful. We can use that to manage our memory allocations. What if the Foo class allocated some memory on the heap in its constructor, and deleted that memory in its destructor. Then we could get the best of both worlds, safe memory allocations that are guaranteed to be freed again, but without the limitations of forcing everything to be on the stack.

And that is pretty much exactly how most C++ code works. Look at the standard library's std::vector for example. That is typically allocated on the stack, but can be dynamically sized and resized. And it does this by internally allocating memory on the heap as necessary. The user of the class never sees this, so there's no chance of leaking memory, or forgetting to clean up what you allocated.

This principle is called RAII (Resource Acquisition is Initialization), and it can be extended to any resource that must be acquired and released. (network sockets, files, database connections, synchronization locks). All of them can be acquired in the constructor, and released in the destructor, so you're guaranteed that all resources you acquire will get freed again.

As a general rule, never use new/delete directly from your high level code. Always wrap it in a class that can manage the memory for you, and which will ensure it gets freed again. (Yes, there may be exceptions to this rule. In particular, smart pointers require you to call new directly, and pass the pointer to its constructor, which then takes over and ensures delete is called correctly. But this is still a very important rule of thumb)

(SELECT ename FROM EMP WHERE empno = mgr)

There are no records in EMP that meet this criteria.

You need to self-join to get this relation.

SELECT e.ename AS Employee, e.empno, m.ename AS Manager, m.empno
FROM EMP AS e LEFT OUTER JOIN EMP AS m
ON e.mgr =m.empno;

EDIT:

The answer you selected will not list your president because it's an inner join. I'm thinking you'll be back when you discover your output isn't what your (I suspect) homework assignment required. Here's the actual test case:

> select * from emp;

 empno | ename |    job    | deptno | mgr  
-------+-------+-----------+--------+------
  7839 | king  | president |     10 |     
  7698 | blake | manager   |     30 | 7839
(2 rows)

> SELECT e.ename employee, e.empno, m.ename manager, m.empno
FROM emp AS e LEFT OUTER JOIN emp AS m
ON e.mgr =m.empno;

 employee | empno | manager | empno 
----------+-------+---------+-------
 king     |  7839 |         |      
 blake    |  7698 | king    |  7839
(2 rows)

The difference is that an outer join returns all the rows. An inner join will produce the following:

> SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM emp e, emp m
WHERE e.mgr = m.empno;

 ename | empno | manager | mgr  
-------+-------+---------+------
 blake |  7698 | king    | 7839
(1 row)

From the @Tgr's comment, there is an online tool : https://codetabs.com/count-loc/count-loc-online.html

I have found it easiest to use a graphical interface on windows (I recommend mobaXTerm it has ssh, scp, ftp, remote desktop, and many more) but if you are set on command line I would recommend cd'ing into the directory with the source folder then
scp -r yourFolder username@server:/path/to/dir
the -r indicates recursive to be used on directories

You can do kubectl get replicasets check for old deployment based on age or time

Delete old deployment based on time if you want to delete same current running pod of application

kubectl delete replicasets <Name of replicaset>

To add to craig_h's comment above (I currently don't have enough rep to add this as a comment to his answer, sorry), if your primary key is not an integer, you'll also want to tell your model what data type it is, by setting keyType at the top of the model definition.

public $keyType = 'string'

Eloquent understands any of the types defined in the castAttribute() function, which as of Laravel 5.4 are: int, float, string, bool, object, array, collection, date and timestamp.

This will ensure that your primary key is correctly cast into the equivalent PHP data type.

As we know devices running android can have different screen sizes. As we further know views should adjust dynamically and become the space which is appropriate.

If you set a max height you maybe force the view not to get enough space or take to less space. I know that sometimes it seems to be practically to set a max height. But if the resolution will ever change dramatically, and it will!, then the view, which has a max height, will look not appropriate.

i think there is no proper way to exactly do the layout you want. i would recommend you to think over your layout using layout managers and relative mechanisms. i don't know what you're trying to achieve but it sounds a little strange for me that a list should only show three items and then the user has to scroll.

btw. minHeight is not guaranteed (and maybe shouldn't exist either). it can have some benefit to force items to be visible while other relative items get smaller.

You can also do this to set a header for all future gets for the Session object, where x-test will be in all s.get() calls:

s = requests.Session()
s.auth = ('user', 'pass')
s.headers.update({'x-test': 'true'})

# both 'x-test' and 'x-test2' are sent
s.get('http://httpbin.org/headers', headers={'x-test2': 'true'})

from: http://docs.python-requests.org/en/latest/user/advanced/#session-objects

In my case the 1 MB maximum cap for data transport by Intent. I'll just use Cache or Storage.

Using java 8 removeIf

public int getSimilarItems(){
    List<String> one = Arrays.asList("milan", "dingo", "elpha", "hafil", "meat", "iga", "neeta.peeta");
    List<String> two = new ArrayList<>(Arrays.asList("hafil", "iga", "binga", "mike", "dingo")); //Cannot remove directly from array backed collection
    int initial = two.size();

    two.removeIf(one::contains);
    return initial - two.size();
}

You could just make a nice little looping function.

def replace_all(text, dic):
    for i, j in dic.iteritems():
        text = text.replace(i, j)
    return text

where text is the complete string and dic is a dictionary — each definition is a string that will replace a match to the term.

Note: in Python 3, iteritems() has been replaced with items()

Careful: Python dictionaries don't have a reliable order for iteration. This solution only solves your problem if:

• order of replacements is irrelevant
• it's ok for a replacement to change the results of previous replacements

Update: The above statement related to ordering of insertion does not apply to Python versions greater than or equal to 3.6, as standard dicts were changed to use insertion ordering for iteration.

For instance:

d = { "cat": "dog", "dog": "pig"}
my_sentence = "This is my cat and this is my dog."
replace_all(my_sentence, d)
print(my_sentence)

Possible output #1:

"This is my pig and this is my pig."

Possible output #2

"This is my dog and this is my pig."

One possible fix is to use an OrderedDict.

from collections import OrderedDict
def replace_all(text, dic):
    for i, j in dic.items():
        text = text.replace(i, j)
    return text
od = OrderedDict([("cat", "dog"), ("dog", "pig")])
my_sentence = "This is my cat and this is my dog."
replace_all(my_sentence, od)
print(my_sentence)

Output:

"This is my pig and this is my pig."

Careful #2: Inefficient if your text string is too big or there are many pairs in the dictionary.

Suppose the dataframe df has 3 columns id1, name1, price1 and you wish to rename them to id2, name2, price2

val list = List("id2", "name2", "price2")
import spark.implicits._
val df2 = df.toDF(list:_*)
df2.columns.foreach(println)

I found this approach useful in many cases.

I experienced the same problem in VS2008 when I tried to add a X64 build to a project converted from VS2003.

I looked at everything found when searching for this error on Google (Target machine, VC++Directories, DUMPBIN....) and everything looked OK.

Finally I created a new test project and did the same changes and it seemed to work.

Doing a diff between the vcproj files revealed the problem....

My converted project had /MACHINE:i386 set as additional option set under Linker->Command Line. Thus there was two /MACHINE options set (both x64 and i386) and the additional one took preference.

Removing this and setting it properly under Linker->Advanced->Target Machine made the problem disappeared.

g++ does not check for array bounds, and you may be overwriting something with 3,4 but nothing really important, if you try with higher numbers you'll get a crash.

You are just overwriting parts of the stack that are not used, you could continue till you reach the end of the allocated space for the stack and it'd crash eventually

EDIT: You have no way of dealing with that, maybe a static code analyzer could reveal those failures, but that's too simple, you may have similar(but more complex) failures undetected even for static analyzers

In pure JS (provided your browser can handle XHRs, which every major browser [including IE > 6] can):

function igurlretrieve(url) {

  var urldsrc = "http://api.instagram.com/oembed?url=" + url;

  //fetch data from URL data source
  var x = new XMLHttpRequest();
  x.open('GET', urldsrc, true);
  x.send();

  //load resulting JSON data as JS object
  var urldata = JSON.parse(x.responseText);

  //reconstruct data as "instagram://" URL that can be opened in iOS app
  var reconsturl = "instagram://media?id=" + urldata.media_id;
  return reconsturl;

}

Provided this is your goal -- simply opening the page in the Instagram iOS app, which is exactly what this is about -- this should do, especially if you don't want to have to endure licensing fees.

If you can store the json string in a variable jsn_string

import json

jsn_list = json.loads(json.dumps(jsn_string)) 
   for lis in jsn_list:
       for key,val in lis.items():
           print(key, val)

I got this error message with a much more recent ssis version (vs 2015 enterprise, i think it's ssis 2016). I will comment here because this is the first reference that comes up when you google this error message. I think it happens mostly with character columns when the source character size is larger than the target character size. I got this message when I was using an ado.net input to ms sql from a teradata database. Funny because the prior oledb writes to ms sql handled all the character conversion perfectly with no coding overrides. The colid number and the a corresponding Destination Input column # you sometimes get with the colid message are worthless. It's not the column when you count down from the top of the mapping or anything like that. If I were microsoft, I'd be embarrased to give an error message that looks like it's pointing at the problem column when it isn't. I found the problem colid by making an educated guess and then changing the input to the mapping to "Ignore" and then rerun and see if the message went away. In my case and in my environment I fixed it by substr( 'ing the Teradata input to the character size of the ms sql declaration for the output column. Check and make sure your input substr propagates through all you data conversions and mappings. In my case it didn't and I had to delete all my Data Conversion's and Mappings and start over again. Again funny that OLEDB just handled it and ADO.net threw the error and had to have all this intervention to make it work. In general you should use OLEDB when your target is MS Sql.

With custom index:

$arr=array("a"=>"one", "b"=>"two");
    $arr=array("c"=>"three", "d"=>"four").$arr;

    print_r($arr);
    -------------------
    output:

    Array
    (
    [c]=["three"]
    [d]=["four"]
    [a]=["two"]
    [b]=["one"]
    )

From other post:

    find /c "string" file >NUL
    if %errorlevel% equ 1 goto notfound
        echo found
    goto done
    :notfound
        echo notfound
    goto done
    :done

Use the /i switch when you want case insensitive checking:

    find /i /c "string" file >NUL

Or something like: if not found write to file.

    find /c "%%P" file.txt  || ( echo %%P >> newfile.txt )

Or something like: if found write to file.

    find /c "%%P" file.txt  && ( echo %%P >> newfile.txt )

Or something like:

    find /c "%%P" file.txt  && ( echo found ) || ( echo not found )

For more generic advice on debugging this kind of problem MDN have a good article TypeError: "x" is not a function:

It was attempted to call a value like a function, but the value is not actually a function. Some code expects you to provide a function, but that didn't happen.

Maybe there is a typo in the function name? Maybe the object you are calling the method on does not have this function? For example, JavaScript objects have no map function, but JavaScript Array object do.

Basically the object (all functions in js are also objects) does not exist where you think it does. This could be for numerous reasons including(not an extensive list):

• Missing script library
• Typo
• The function is within a scope that you currently do not have access to, e.g.:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//the global scope can't access y because it is closed over in x and not exposed_x000D_
//y is not a function err triggered_x000D_
x.y();

• Your object/function does not have the function your calling:

var x = function(){_x000D_
   var y = function() {_x000D_
      alert('fired y');_x000D_
   }_x000D_
};_x000D_
    _x000D_
//z is not a function error (as above) triggered_x000D_
x.z();

Math.abs(x) or if you are certain the value is negative before the conversion just prepend a regular minus sign: x = -x.

Finally, I get the cell using the following code:

UITableViewCell *cell = (UITableViewCell *)[(UITableView *)self.view cellForRowAtIndexPath:nowIndex];

Because the class is extended UITableViewController:

@interface SearchHotelViewController : UITableViewController

So, the self is "SearchHotelViewController".

<div  style="display:none;" class="answer_list" > WELCOME</div>
<input type="button" name="answer" onclick="document.getElementsByClassName('answer_list')[0].style.display = 'auto';">

1. First should understand the error meaning

Error not enough values to unpack (expected 3, got 2) means:

a 2 part tuple, but assign to 3 values

and I have written demo code to show for you:

#!/usr/bin/python
# -*- coding: utf-8 -*-
# Function: Showing how to understand ValueError 'not enough values to unpack (expected 3, got 2)'
# Author: Crifan Li
# Update: 20191212

def notEnoughUnpack():
    """Showing how to understand python error `not enough values to unpack (expected 3, got 2)`"""
    # a dict, which single key's value is two part tuple
    valueIsTwoPartTupleDict = {
        "name1": ("lastname1", "email1"),
        "name2": ("lastname2", "email2"),
    }

    # Test case 1: got value from key
    gotLastname, gotEmail = valueIsTwoPartTupleDict["name1"] # OK
    print("gotLastname=%s, gotEmail=%s" % (gotLastname, gotEmail))
    # gotLastname, gotEmail, gotOtherSomeValue = valueIsTwoPartTupleDict["name1"] # -> ValueError not enough values to unpack (expected 3, got 2)

    # Test case 2: got from dict.items()
    for eachKey, eachValues in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValues=%s" % (eachKey, eachValues))
    # same as following:
    # Background knowledge: each of dict.items() return (key, values)
    # here above eachValues is a tuple of two parts
    for eachKey, (eachValuePart1, eachValuePart2) in valueIsTwoPartTupleDict.items():
        print("eachKey=%s, eachValuePart1=%s, eachValuePart2=%s" % (eachKey, eachValuePart1, eachValuePart2))
    # but following:
    for eachKey, (eachValuePart1, eachValuePart2, eachValuePart3) in valueIsTwoPartTupleDict.items(): # will -> ValueError not enough values to unpack (expected 3, got 2)
        pass

if __name__ == "__main__":
    notEnoughUnpack()

using VSCode debug effect:

2. For your code

for name, email, lastname in unpaidMembers.items():

but error ValueError: not enough values to unpack (expected 3, got 2)

means each item(a tuple value) in unpaidMembers, only have 1 parts:email, which corresponding above code

    unpaidMembers[name] = email

so should change code to:

for name, email in unpaidMembers.items():

to avoid error.

But obviously you expect extra lastname, so should change your above code to

    unpaidMembers[name] = (email, lastname)

and better change to better syntax:

for name, (email, lastname) in unpaidMembers.items():

then everything is OK and clear.

if you want to collapse and expand particular loop, if else then install following plugins for visual studio.

• VS2010
• VS2012
• VS2013
• VS2015

Just add this to config

<system.net>
    <defaultProxy useDefaultCredentials="true" >
    </defaultProxy>
</system.net>

<?php 
  ${test}="test information";
  echo $test;
?>

Notice: Use of undefined constant test - assumed 'test' in D:\xampp\htdocs\sp\test\envoirnmentVariables.php on line 3 test information

Extracting text from PDF is a hard problem because PDF has such a layout-oriented structure. You can see the docs and source code of my barely-successful attempt on CPAN (my implementation is in Perl). The PDF data structure is very cool and well designed, but it's easier to write than read.

malloc() (and its friends free() and realloc()) is the way to do this in C.

Here is my combined solution for various PHP versions.

In my company we are working with different servers with various PHP versions, so I had to find solution working for all.

$phpVersion = substr(phpversion(), 0, 3)*1;

if($phpVersion >= 5.4) {
  $encodedValue = json_encode($value, JSON_UNESCAPED_UNICODE);
} else {
  $encodedValue = preg_replace('/\\\\u([a-f0-9]{4})/e', "iconv('UCS-4LE','UTF-8',pack('V', hexdec('U$1')))", json_encode($value));
}

Credits should go to Marco Gasi & abu. The solution for PHP >= 5.4 is provided in the json_encode docs.

I use environment for that. It works automatically and you don't have to create new injectable service and most usefull for me, don't need to import via constructor.

1) Create environment variable in your environment.ts

export const environment = {
    ...
    // runtime variables
    isContentLoading: false,
    isDeployNeeded: false
}

2) Import environment.ts in *.ts file and create public variable (i.e. "env") to be able to use in html template

import { environment } from 'environments/environment';

@Component(...)
export class TestComponent {
    ...
    env = environment;
}

3) Use it in template...

<app-spinner *ngIf='env.isContentLoading'></app-spinner>

in *.ts ...

env.isContentLoading = false 

(or just environment.isContentLoading in case you don't need it for template)

You can create your own set of globals within environment.ts like so:

export const globals = {
    isContentLoading: false,
    isDeployNeeded: false
}

and import directly these variables (y)

String time = "12:32:22";
String[] values = time.split(":");

This will take your time and split it where it sees a colon and put the value in an array, so you should have 3 values after this.

Then loop through string array and convert each one. (with Integer.parseInt)

Here is example how to remove NULL characters using ex (in-place):

ex -s +"%s/\%x00//g" -cwq nulls.txt

and for multiple files:

ex -s +'bufdo!%s/\%x00//g' -cxa *.txt

^{For recursivity, you may use globbing option **/*.txt (if it is supported by your shell).}

Useful for scripting since sed and its -i parameter is a non-standard BSD extension.

I wrote the HTML table in JSP. Course is is a type. For example Course cs, cs= object of type Course which had 2 attributes: id, title. courses is an ArrayList of Course objects.

The HTML table displays all the courses titles in each cell. So the table has 1 column only: Course1 Course2 Course3 ...... Taking aside:

 onclick="DoNav('http://localhost:8080/Mydata/ComplexSearch/FoundS.jsp?courseId=<%=cs.getCourseId()%>');"

This means that after user selects a table cell, for example "Course2", the title of the course- "Course2" will travel to the page where the URL is directing the user: http://localhost:8080/Mydata/ComplexSearch/FoundS.jsp . "Course2" will arrive in FoundS.jsp page. The identifier of "Course2" is courseId. To declare the variable courseId, in which CourseX will be kept, you put a "?" after the URL and next to it the identifier. It works.
