Use __LINE__ (that's double-underscore LINE double-underscore), the preprocessor will replace it with the line number on which it is encountered.

import datetime

now = datetime.datetime.now()
start_month = datetime.datetime(now.year, now.month, 1)
date_on_next_month = start_month + datetime.timedelta(35)
start_next_month = datetime.datetime(date_on_next_month.year, date_on_next_month.month, 1)
last_day_month = start_next_month - datetime.timedelta(1)

You're also not going to get the output you're hoping for as long as you append to listoflists only inside the if-clause.

Try something like this instead:

import copy

listoflists = []
list = []
for i in range(0,10):
    list.append(i)
    if len(list)>3:
        list.remove(list[0])
    listoflists.append((copy.copy(list), copy.copy(list[0])))
print(listoflists)

Here is a work around but not always a great one, depending on how much you scale it. Explanation can be found here: https://www.geekgoddess.com/how-to-resize-the-google-nocaptcha-recaptcha/

.g-recaptcha {
    transform:scale(0.77);
    transform-origin:0 0;
}

UPDATE: Google has added support for a smaller size via a parameter. Have a look at the docs - https://developers.google.com/recaptcha/docs/display#render_param

Let's get pedantic, because there are differences that can actually affect your code's behavior. Much of the following is taken from comments made to an "Old New Thing" article.

Sometimes the memory returned by the new operator will be initialized, and sometimes it won't depending on whether the type you're newing up is a POD (plain old data), or if it's a class that contains POD members and is using a compiler-generated default constructor.

• In C++1998 there are 2 types of initialization: zero and default
• In C++2003 a 3rd type of initialization, value initialization was added.

Assume:

struct A { int m; }; // POD
struct B { ~B(); int m; }; // non-POD, compiler generated default ctor
struct C { C() : m() {}; ~C(); int m; }; // non-POD, default-initialising m

In a C++98 compiler, the following should occur:

• new A - indeterminate value

• new A() - zero-initialize

• new B - default construct (B::m is uninitialized)

• new B() - default construct (B::m is uninitialized)

• new C - default construct (C::m is zero-initialized)

• new C() - default construct (C::m is zero-initialized)

In a C++03 conformant compiler, things should work like so:

• new A - indeterminate value

• new A() - value-initialize A, which is zero-initialization since it's a POD.

• new B - default-initializes (leaves B::m uninitialized)

• new B() - value-initializes B which zero-initializes all fields since its default ctor is compiler generated as opposed to user-defined.

• new C - default-initializes C, which calls the default ctor.

• new C() - value-initializes C, which calls the default ctor.

So in all versions of C++ there's a difference between new A and new A() because A is a POD.

And there's a difference in behavior between C++98 and C++03 for the case new B().

This is one of the dusty corners of C++ that can drive you crazy. When constructing an object, sometimes you want/need the parens, sometimes you absolutely cannot have them, and sometimes it doesn't matter.

Pretty sure this solves what you're looking for:

HTML:

<table>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
    <tr><td><button class="editbtn">edit</button></td></tr>
</table>

Javascript (using jQuery):

$(document).ready(function(){
    $('.editbtn').click(function(){
        $(this).html($(this).html() == 'edit' ? 'modify' : 'edit');
    });
});

Edit:

Apparently I should have looked at your sample code first ;)

You need to change (at least) the ID attribute of each element. The ID is the unique identifier for each element on the page, meaning that if you have multiple items with the same ID, you'll get conflicts.

By using classes, you can apply the same logic to multiple elements without any conflicts.

JSFiddle sample

this gives you the Xact;

System.Data.SqlClient.SqlConnectionStringBuilder connBuilder = new System.Data.SqlClient.SqlConnectionStringBuilder();

connBuilder.ConnectionString = connectionString;

string server = connBuilder.DataSource;           //-> this gives you the Server name.
string database = connBuilder.InitialCatalog;     //-> this gives you the Db name.

Inspired by the pyspark/tests.py I did

def quiet_logs(sc):
    logger = sc._jvm.org.apache.log4j
    logger.LogManager.getLogger("org"). setLevel( logger.Level.ERROR )
    logger.LogManager.getLogger("akka").setLevel( logger.Level.ERROR )

Calling this just after creating SparkContext reduced stderr lines logged for my test from 2647 to 163. However creating the SparkContext itself logs 163, up to

15/08/25 10:14:16 INFO SparkDeploySchedulerBackend: SchedulerBackend is ready for scheduling beginning after reached minRegisteredResourcesRatio: 0.0

and it's not clear to me how to adjust those programmatically.

I just had this error message running IIS Express in Visual Studio 2015. In my case I needed to be running the 64 bit version of IIS Express:

Tools ? Options ? Projects and Solutions ? Web Projects
Check the box that says "Use the 64 bit version of IIS Express for web sites and projects".

Screenshot:

There are some kind of misunderstanding about lazy collections in JPA-Hibernate. First of all let's clear that why trying to read a lazy collection throws exceptions and not just simply returns NULL for converting or further use cases?.

That's because Null fields in Databases especially in joined columns have meaning and not simply not-presented state, like programming languages. when you're trying to interpret a lazy collection to Null value it means (on Datastore-side) there is no relations between these entities and it's not true. so throwing exception is some kind of best-practice and you have to deal with that not the Hibernate.

So as mentioned above I recommend to :

1. Detach the desired object before modifying it or using stateless session for querying
2. Manipulate lazy fields to desired values (zero,null,etc.)

also as described in other answers there are plenty of approaches(eager fetch, joining etc.) or libraries and methods for doing that, but you have to setting up your view of what's happening before dealing with the problem and solving it.

There is also another approach without the use of DomXPath or Zend_Dom_Query.

Based on dav's original function, I wrote the following function that returns all the children of the parent node whose tag and class match the parameters.

function getElementsByClass(&$parentNode, $tagName, $className) {
    $nodes=array();

    $childNodeList = $parentNode->getElementsByTagName($tagName);
    for ($i = 0; $i < $childNodeList->length; $i++) {
        $temp = $childNodeList->item($i);
        if (stripos($temp->getAttribute('class'), $className) !== false) {
            $nodes[]=$temp;
        }
    }

    return $nodes;
}

suppose you have a variable $html the following HTML:

<html>
 <body>
  <div id="content_node">
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>
    <p class="a">I am in the content node.</p>    
  </div>
  <div id="footer_node">
    <p class="a">I am in the footer node.</p>
  </div>
 </body>
</html>

use of getElementsByClass is as simple as:

$dom = new DOMDocument('1.0', 'utf-8');
$dom->loadHTML($html);
$content_node=$dom->getElementById("content_node");

$div_a_class_nodes=getElementsByClass($content_node, 'div', 'a');//will contain the three nodes under "content_node".

Google recommends:

• Network Link Conditioner on OSX
• Clumsy on Windows
• Dummynet on Linux

I think it needs to be checked if any row is selected or not? The below code would check it:

var entityGrid = $("#EntitesGrid").data("kendoGrid");
            var selectedItem = entityGrid.dataItem(entityGrid.select());
            if (selectedItem != undefined)
                alert("The Row Is SELECTED");
            else
                alert("NO Row Is SELECTED")

I think I observed a similar problem: some processes started, seemed to run successfully but never completed. The function waitFor() was waiting forever except if I killed the process in Task Manager.
However, everything worked well in cases the length of the command line was 127 characters or shorter. If long file names are inevitable you may want to use environmental variables, which may allow you keeping the command line string short. You can generate a batch file (using FileWriter) in which you set your environmental variables before calling the program you actually want to run. The content of such a batch could look like:

    set INPUTFILE="C:\Directory 0\Subdirectory 1\AnyFileName"
    set OUTPUTFILE="C:\Directory 2\Subdirectory 3\AnotherFileName"
    set MYPROG="C:\Directory 4\Subdirectory 5\ExecutableFileName.exe"
    %MYPROG% %INPUTFILE% %OUTPUTFILE%

Last step is running this batch file using Runtime.

!=== will not work because it's a syntax error. The correct way is !== (not three "equal to" symbols)

ALTER TABLE `stor` ADD `buy_price` INT(20) NOT NULL ;

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<a href="xxx.html" style="text-decoration:none;">goto this link</a>

Inline stylesheet:

<html>
<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

External stylesheet:

<html>
<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>
<body>
<a href="xxx.html">goto this link</a>
</body>
</html>

stylesheet.css:

a {
      text-decoration:none;
   }

Normally that error occurs when a } was missed somewhere in the code, for example:

void mi_start_curr_serv(void){
    #if 0
    //stmt
    #endif

would fail with this error due to the missing } at the end of the function. The code you posted doesn't have this error, so it is likely coming from some other part of your source.

I had the same issue! I was unable to change/set the ID attribute of elements. It worked in all other browsers but not IE. It probably isn't relevant to your problem but here is what I ended up doing:

Background

I was building an MVC site with jquery tabs. I wanted to create tabs dynamically and do an AJAX postback to the server saving the tab in the database. I wanted to use a unique identifier, in the form of an int, for the tabs so I wouldn't get in to trouble if a user created two tabs with the same name. I then used the unique ID to identify the tabs like:

<ul>
<li><a href='#{href}'>#{label}</a> <span class='ui-icon ui-icon-close'>Remove List</span></li>
<ul>

When I then implemented the remove functions on the tabs the callback uses the index, witch is 0 based. Then I had no way to sending back the unique ID to the server to trash the DB entry. The callback for the tabremove event gives the jquery event and ui parameters. With one line of code I could get the ID of the span:

var dbIndex = event.currentTarget.id;

The problem was that the span tag didn't have any ID. So in the create callback I tried to set the ID buy extracting the ID from the a href like this:

ui.tab.parentNode.id = ui.tab.href.substring(ui.tab.href.indexOf('#list-') + 6);

That worked fine in FireFox but not in IE. So I tried a few other:

//ui.tab.parentNode.setAttribute('id', ui.tab.href.substring(ui.tab.href.indexOf('#list-') + 6));
//$(ui.tab.parentNode).attr({'id':ui.tab.href.substring(ui.tab.href.indexOf('#list-') + 6)});
//ui.tab.parentNode.id.value = ui.tab.href.substring(ui.tab.href.indexOf('#list-') + 6);

None of them worked! So after a few hours of test and Googeling I gave up and draw the conclusion that IE cant set the ID attribute of an element dynamically.

As I sad this is probably not relevant to your issue but I thought I would share.

Solution

And for all of you who found this by Googleing on the tabs issue I had here is what I ended up doing in the tabsremove callback to solve the issue:

var dbIndex = event.currentTarget.offsetParent.childNodes[0].href.substring(event.currentTarget.offsetParent.childNodes[0].href.indexOf('#list-') + 6);

Probably not the sexiest solution but hey it solved the issue. If anyone have any input please share...

You can use the mt and mb spacing utilities to add extra margins to the <hr>, for example:

<hr class="mt-5 mb-5">

https://getbootstrap.com/docs/4.3/utilities/spacing/

The question is old, but still receives a lot of attention. As the existing answers are outdated, here a more up-to-date solution:

Resizing local images

As of knitr 1.12, there is the function include_graphics. From ?include_graphics (emphasis mine):

The major advantage of using this function is that it is portable in the sense that it works for all document formats that knitr supports, so you do not need to think if you have to use, for example, LaTeX or Markdown syntax, to embed an external image. Chunk options related to graphics output that work for normal R plots also work for these images, such as out.width and out.height.

Example:

```{r, out.width = "400px"}
knitr::include_graphics("path/to/image.png")
```

Advantages:

• Over agastudy's answer: No need for external libraries or for re-rastering the image.
• Over Shruti Kapoor's answer: No need to manually write HTML. Besides, the image is included in the self-contained version of the file.

Including generated images

To compose the path to a plot that is generated in a chunk (but not included), the chunk options opts_current$get("fig.path") (path to figure directory) as well as opts_current$get("label") (label of current chunk) may be useful. The following example uses fig.path to include the second of two images which were generated (but not displayed) in the first chunk:

```{r generate_figures, fig.show = "hide"}
library(knitr)
plot(1:10, col = "green")
plot(1:10, col = "red")
```

```{r}
include_graphics(sprintf("%sgenerate_figures-2.png", opts_current$get("fig.path")))
```

The general pattern of figure paths is [fig.path]/[chunklabel]-[i].[ext], where chunklabel is the label of the chunk where the plot has been generated, i is the plot index (within this chunk) and ext is the file extension (by default png in RMarkdown documents).

MySQL documentation covers this topic.

Here is a synopsis. When using join or inner join, the on condition is optional. This is different from the ANSI standard and different from almost any other database. The effect is a cross join. Similarly, you can use an on clause with cross join, which also differs from standard SQL.

A cross join creates a Cartesian product -- that is, every possible combination of 1 row from the first table and 1 row from the second. The cross join for a table with three rows ('a', 'b', and 'c') and a table with four rows (say 1, 2, 3, 4) would have 12 rows.

In practice, if you want to do a cross join, then use cross join:

from A cross join B

is much better than:

from A, B

and:

from A join B -- with no on clause

The on clause is required for a right or left outer join, so the discussion is not relevant for them.

If you need to understand the different types of joins, then you need to do some studying on relational databases. Stackoverflow is not an appropriate place for that level of discussion.

The problem is that the keys provided in the loop do not refer to the index of the file.

for (var i in this.files) {
    console.log(i);
}

The output of the above code is:

0
length
item

But what was expected was:

0
1
2
etc...

Then the error occurs when the browser tries to execute, for example:

window.URL.createObjectURL(this.files["length"])

I suggest implementation based on the following code:

var files = this.files;
for (var i = 0; i < files.length; i++) {
    var file = files[i],
        src = (window.URL || window.webkitURL).createObjectURL(file);
    ...
}

I hope this can help someone.

When you have three columns : first_name, last_name, mid_name:

SELECT CASE 
    WHEN mid_name IS NULL OR TRIM(mid_name) ='' THEN
        CONCAT_WS( " ", first_name, last_name ) 
    ELSE 
        CONCAT_WS( " ", first_name, mid_name, last_name ) 
    END

If you are familiar with RxJava, you can use Observable.interval(), which is pretty neat.

Observable.interval(60, TimeUnits.SECONDS)
          .flatMap(new Function<Long, ObservableSource<String>>() {
                @Override
                public ObservableSource<String> apply(@NonNull Long aLong) throws Exception {
                    return getDataObservable(); //Where you pull your data
                }
            });

The downside of this is that you have to architect polling your data in a different way. However, there are a lot of benefits to the Reactive Programming way:

1. Instead of controlling your data via a callback, you create a stream of data that you subscribe to. This separates the concern of "polling data" logic and "populating UI with your data" logic so that you do not mix your "data source" code and your UI code.

2. With RxAndroid, you can handle threads in just 2 lines of code.

   Observable.interval(60, TimeUnits.SECONDS)
         .flatMap(...) // polling data code
         .subscribeOn(Schedulers.newThread()) // poll data on a background thread
         .observeOn(AndroidSchedulers.mainThread()) // populate UI on main thread
         .subscribe(...); // your UI code
   

Please check out RxJava. It has a high learning curve but it will make handling asynchronous calls in Android so much easier and cleaner.

Theres a few ways you can do this. You can either add a background to the canvas you are currently working on, which if the canvas isn't going to be redrawn every loop is fine. Otherwise you can make a second canvas underneath your main canvas and draw the background to it. The final way is to just use a standard <img> element placed under the canvas. To draw a background onto the canvas element you can do something like the following:

Live Demo

var canvas = document.getElementById("canvas"),
    ctx = canvas.getContext("2d");

canvas.width = 903;
canvas.height = 657;


var background = new Image();
background.src = "http://www.samskirrow.com/background.png";

// Make sure the image is loaded first otherwise nothing will draw.
background.onload = function(){
    ctx.drawImage(background,0,0);   
}

// Draw whatever else over top of it on the canvas.

i used Mofi sample, and change some parameters, no you can do -t

@%SystemRoot%\system32\ping.exe -n -1 4.2.2.4

I had this problem after moving the htdocs folder to outside the xampp folder. If you do this then you need to change the document root in httpd.conf. See https://stackoverflow.com/a/1414/3543329.

Have a read of the urllib Missing Manual. Pulled from there is the following simple example of a POST request.

url = 'http://myserver/post_service'
data = urllib.urlencode({'name' : 'joe', 'age'  : '10'})
req = urllib2.Request(url, data)
response = urllib2.urlopen(req)
print response.read()

As suggested by @Michael Kent do consider requests, it's great.

EDIT: This said, I do not know why passing data to urlopen() does not result in a POST request; It should. I suspect your server is redirecting, or misbehaving.

I have a Toolbar in my Activity and a Base Activity that overrides all Titles. So I had to use setTitle in onResume() in the Activity like so:

@Override
  protected void onResume() {
    super.onResume();
    toolbar.setTitle(R.string.title);
  }

I had same problem. The origin of the problem was the creation of text file in Notepad and renaming it as a java file. This implied that the file was saved as WorCount.java.txt file.

To solve this I had to save the file as java file in an IDE or in Nodepad++.

You need to set the timeout to "None" when you open the serial port:

ser = serial.Serial(**bco_port**, timeout=None, baudrate=115000, xonxoff=False, rtscts=False, dsrdtr=False) 

This is a blocking command, so you are waiting until you receive data that has newline (\n or \r\n) at the end: line = ser.readline()

Once you have the data, it will return ASAP.

When you write to the file via file output stream, the file will be created automatically. but make sure all necessary directories ( folders) are created.

    String absolutePath = ...
    try{
       File file = new File(absolutePath);
       file.mkdirs() ;
       //all parent folders are created
       //now the file will be created when you start writing to it via FileOutputStream.
      }catch (Exception e){
        System.out.println("Error : "+ e.getmessage());
       }

In order to use API tokens, users will have to obtain their own tokens, each from https://<jenkins-server>/me/configure or https://<jenkins-server>/user/<user-name>/configure. It is up to you, as the author of the script, to determine how users supply the token to the script. For example, in a Bourne Shell script running interactively inside a Git repository, where .gitignore contains /.jenkins_api_token, you might do something like:

api_token_file="$(git rev-parse --show-cdup).jenkins_api_token"
api_token=$(cat "$api_token_file" || true)
if [ -z "$api_token" ]; then
    echo
    echo "Obtain your API token from $JENKINS_URL/user/$user/configure"
    echo "After entering here, it will be saved in $api_token_file; keep it safe!"
    read -p "Enter your Jenkins API token: " api_token
    echo $api_token > "$api_token_file"
fi
curl -u $user:$api_token $JENKINS_URL/someCommand

Please note that you can use view.setZ(float) starting from API level 21. Here you can find more info.

<Snippet name="abc"> 

name is an attribute, not an element. That's why it's failing. Look into using SetAttribute on the <Snippet> element.

root.SetAttribute("name", "name goes here");

If you are not required to use Apple's look and feel, a simple fix is to put the following code in your application or applet, before you add any GUI components to your JFrame or JApplet:

 try {
    UIManager.setLookAndFeel( UIManager.getCrossPlatformLookAndFeelClassName() );
 } catch (Exception e) {
            e.printStackTrace();
 }

That will set the look and feel to the cross-platform look and feel, and the setBackground() method will then work to change a JButton's background color.

You cannot store a class object into a string using toString(), toString() only returns a String representation of your object-in any way you'd like. You might want to do some reading about Serialization.

Your variable declarations and their scope are correct. The problem you are facing is that the first AJAX request may take a little bit time to finish. Therefore, the second URL will be filled with the value of sID before the its content has been set. You have to remember that AJAX request are normally asynchronous, i.e. the code execution goes on while the data is being fetched in the background.

You have to nest the requests:

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   obj = name;   // sID is only now available!   sID = obj.id;   console.log(sID); }); 

• Put the second request into a function
• and let it accept sID as a parameter, so you don't have to declare it globally anymore! (Global variables are almost always evil!)
• Remove sID and obj variables - name.id is sufficient unless you really need the other variables outside the function.

$.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.1/summoner/by-name/"+input+"?api_key=API_KEY_HERE"  , function(name){   // We don't need sID or obj here - name.id is sufficient   console.log(name.id);    doSecondRequest(name.id); });  /// TODO Choose a better name function doSecondRequest(sID) {   $.getJSON("https://prod.api.pvp.net/api/lol/eune/v1.2/stats/by-summoner/" + sID + "/summary?api_key=API_KEY_HERE", function(stats){         console.log(stats);   }); }

If you have floats you can write a function and then use that e.g.

#!/bin/bash

function float_gt() {
    perl -e "{if($1>$2){print 1} else {print 0}}"
}

x=3.14
y=5.20
if [ $(float_gt $x $y) == 1 ] ; then
    echo "do stuff with x"
else
    echo "do stuff with y"

Don't abuse private fields get/set by reflection

Using reflection as that is done in several answers here is something that we could avoid.
It brings a small value here while it presents multiple drawbacks :

• we detect reflection issues only at runtime (ex: fields not existing any longer)
• We want encapsulation but not a opaque class that hides dependencies that should be visible and make the class more opaque and less testable.
• it encourages bad design. Today you declare a @Value String field. Tomorrow you can declare 5 or 10 of them in that class and you may not even be straight aware that you decrease the design of the class. With a more visible approach to set these fields (such as constructor) , you will think twice before adding all these fields and you will probably encapsulate them into another class and use @ConfigurationProperties.

Make your class testable both unitary and in integration

To be able to write both plain unit tests (that is without a running spring container) and integration tests for your Spring component class, you have to make this class usable with or without Spring.
Running a container in an unit test when it is not required is a bad practice that slows down local builds : you don't want that.
I added this answer because no answer here seems to show this distinction and so they rely on a running container systematically.

So I think that you should move this property defined as an internal of the class :

@Component
public class Foo{   
    @Value("${property.value}") private String property;
    //...
}

into a constructor parameter that will be injected by Spring :

@Component
public class Foo{   
    private String property;
     
    public Foo(@Value("${property.value}") String property){
       this.property = property;
    }

    //...         
}

Unit test example

You can instantiate Foo without Spring and inject any value for property thanks to the constructor :

public class FooTest{

   Foo foo = new Foo("dummyValue");

   @Test
   public void doThat(){
      ...
   }
}

Integration test example

You can injecting the property in the context with Spring Boot in this simple way thanks to the properties attribute of @SpringBootTest :

@SpringBootTest(properties="property.value=dummyValue")
public class FooTest{
    
   @Autowired
   Foo foo;
     
   @Test
   public void doThat(){
       ...
   }    
}

You could use as alternative @TestPropertySource but it adds an additional annotation :

@SpringBootTest
@TestPropertySource(properties="property.value=dummyValue")
public class FooTest{ ...}

With Spring (without Spring Boot), it should be a little more complicated but as I didn't use Spring without Spring Boot from a long time I don't prefer say a stupid thing.

As a side note : if you have many @Value fields to set, extracting them into a class annotated with @ConfigurationProperties is more relevant because we don't want a constructor with too many arguments.

Simply add Templates URL:

<a href="{% url 'service_data' d.id %}">
 ...XYZ
</a>

This is what worked for me, adapted from Adding HTTP Headers to WCF Calls

// Message inspector used to add the User-Agent HTTP Header to the WCF calls for Server
public class AddUserAgentClientMessageInspector : IClientMessageInspector
{
    public object BeforeSendRequest(ref System.ServiceModel.Channels.Message request, IClientChannel channel)
    {
        HttpRequestMessageProperty property = new HttpRequestMessageProperty();

        var userAgent = "MyUserAgent/1.0.0.0";

        if (request.Properties.Count == 0 || request.Properties[HttpRequestMessageProperty.Name] == null)
        {
            var property = new HttpRequestMessageProperty();
            property.Headers["User-Agent"] = userAgent;
            request.Properties.Add(HttpRequestMessageProperty.Name, property);
        }
        else
        {
            ((HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name]).Headers["User-Agent"] = userAgent;
        }
        return null;
    }

    public void AfterReceiveReply(ref System.ServiceModel.Channels.Message reply, object correlationState)
    {
    }
}

// Endpoint behavior used to add the User-Agent HTTP Header to WCF calls for Server
public class AddUserAgentEndpointBehavior : IEndpointBehavior
{
    public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
    {
        clientRuntime.MessageInspectors.Add(new AddUserAgentClientMessageInspector());
    }

    public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
    {
    }

    public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
    {
    }

    public void Validate(ServiceEndpoint endpoint)
    {
    }
}

After declaring these classes you can add the new behavior to your WCF client like this:

client.Endpoint.Behaviors.Add(new AddUserAgentEndpointBehavior());

Should be as simple as:

git remote set-url origin git://new.url.here

This way you keep the name origin for your new repo - then push to the new repo the old one as detailed in the other answers. Supposing you work alone and you have a local repo you want to mirror with all your cruft in it, you might as well (from inside your local repo)

git push origin --mirror # origin points to your new repo

but see Is "git push --mirror" sufficient for backing up my repository? (in all don't use --mirror but once).

The problem is that you forgot to import os. Add this line of code:

import os

And everything should be fine. Hope this helps!

[class*="test"],[class="second"] {
background: #ffff00;
}

function _formatDatetime(date: Date, format: string) {
   const _padStart = (value: number): string => value.toString().padStart(2, '0');
return format
    .replace(/yyyy/g, _padStart(date.getFullYear()))
    .replace(/dd/g, _padStart(date.getDate()))
    .replace(/mm/g, _padStart(date.getMonth() + 1))
    .replace(/hh/g, _padStart(date.getHours()))
    .replace(/ii/g, _padStart(date.getMinutes()))
    .replace(/ss/g, _padStart(date.getSeconds()));
}
function isValidDate(d: Date): boolean {
    return !isNaN(d.getTime());
}
export function formatDate(date: any): string {
    var datetime = new Date(date);
    return isValidDate(datetime) ? _formatDatetime(datetime, 'yyyy-mm-dd hh:ii:ss') : '';
}

Set the "AutoSizeColumnsMode" property to "Fill".. By default it is set to 'NONE'. Now columns will be filled across the DatagridView. Then you can set the width of other columns accordingly.

DataGridView1.Columns[0].Width=100;// The id column 
DataGridView1.Columns[1].Width=200;// The abbrevation columln
//Third Colulmns 'description' will automatically be resized to fill the remaining 
//space

Use subprocess.Popen:

import subprocess
process = subprocess.Popen(['ls', '-a'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
out, err = process.communicate()
print(out)

Note that communicate blocks until the process terminates. You could use process.stdout.readline() if you need the output before it terminates. For more information see the documentation.

[2017-07-25] since this continues to be the accepted answer, despite being a very hacky solution, I'm incorporating Gabi's code into it, leaving my own to serve as a bad example.

// my hacky approach:
function get_content() {
  var html = document.getElementById("txt").innerHTML;
  document.getElementById("txt").innerHTML = html.replace(/<[^>]*>/g, "");
}
// Gabi's elegant approach, but eliminating one unnecessary line of code:
function gabi_content() {
  var element = document.getElementById('txt');
  element.innerHTML = element.innerText || element.textContent;
}
// and exploiting the fact that IDs pollute the window namespace:
function txt_content() {
  txt.innerHTML = txt.innerText || txt.textContent;
}

.A {
  background: blue;
}

.B {
  font-style: italic;
}

.C {
  font-weight: bold;
}

<input type="button" onclick="get_content()" value="Get Content (bad)" />
<input type="button" onclick="gabi_content()" value="Get Content (good)" />
<input type="button" onclick="txt_content()" value="Get Content (shortest)" />
<p id='txt'>
  <span class="A">I am</span>
  <span class="B">working in </span>
  <span class="C">ABC company.</span>
</p>

here is a pure-javascript, minimalistic approach. I use JQuery but you can use any library (or even no libraries at all).

<html>
    <head>
        <title>An example</title>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
        <script>
            function call_counter(url, pk) {
                window.open(url);
                $.get('YOUR_VIEW_HERE/'+pk+'/', function (data) {
                    alert("counter updated!");
                });
            }
        </script>
    </head>
    <body>
        <button onclick="call_counter('http://www.google.com', 12345);">
            I update object 12345
        </button>
        <button onclick="call_counter('http://www.yahoo.com', 999);">
            I update object 999
        </button>
    </body>
</html>

Alternative approach

Instead of placing the JavaScript code, you can change your link in this way:

<a target="_blank" 
    class="btn btn-info pull-right" 
    href="{% url YOUR_VIEW column_3_item.pk %}/?next={{column_3_item.link_for_item|urlencode:''}}">
    Check It Out
</a>

and in your views.py:

def YOUR_VIEW_DEF(request, pk):
    YOUR_OBJECT.objects.filter(pk=pk).update(views=F('views')+1)
    return HttpResponseRedirect(request.GET.get('next')))

1) echo logpath=F:\mongodb\log\mongo.log > F:\mongodb\mongod.cfg

2) dbpath=F:\mongodb\data\db [add this to the next line in mongod.cfg]

C:\>F:\mongodb\bin\mongod.exe –config F:\mongodb\mongod.cfg –install

Reference

No one should ever have to keep writing app.use('/someRoute', require('someFile')) until it forms a heap of code.

It just doesn't make sense at all to be spending time invoking/defining routings. Even if you do need custom control, it's probably only for some of the time, and for the most bit you want to be able to just create a standard file structure of routings and have a module do it automatically.

Try Route Magic

As you scale your app, the routing invocations will start to form a giant heap of code that serves no purpose. You want to do just 2 lines of code to handle all the app.use routing invocations with Route Magic like this:

const magic = require('express-routemagic')
magic.use(app, __dirname, '[your route directory]')

For those you want to handle manually, just don't use pass the directory to Magic.

There are three ways to do this, depending on your needs. You could use the old-school C way and call fopen/fread/fclose, or you could use the C++ fstream facilities (ifstream/ofstream), or if you're using MFC, use the CFile class, which provides functions to accomplish actual file operations.

All of these are suitable for both text and binary, though none have a specific readline functionality. What you'd most likely do instead in that case is use the fstream classes (fstream.h) and use the stream operators (<< and >>) or the read function to read/write blocks of text:

int nsize = 10;
char *somedata;
ifstream myfile;
myfile.open("<path to file>");
myfile.read(somedata,nsize);
myfile.close();

Note that, if you're using Visual Studio 2005 or higher, traditional fstream may not be available (there's a new Microsoft implementation, which is slightly different, but accomplishes the same thing).

I am using Spring STS 3.8.3. I had a similar problem. I fixed it by using information from this thread And also by fixing some maven settings. click Spring Tool Suite -> Preferences -> Maven and uncheck the box that says "Do not automatically update dependencies from remote depositories" Also I checked the boxes that say "Download Artifact Sources" and "download Artifact javadoc".

for VS2008 with feature pack update, shared_ptr can be found under namespace std::tr1.

std::tr1::shared_ptr<int> MyIntSmartPtr = new int;

of

if you had boost installation path (for example @ C:\Program Files\Boost\boost_1_40_0) added to your IDE settings:

#include <boost/shared_ptr.hpp>

Issue: Your branch is based on 'origin/master', but the upstream is gone.

Solution: git branch --unset-upstream

There is an infinity in the NumPy library: from numpy import inf. To get negative infinity one can simply write -inf.

Aside from all the steps Luke and Vaiden recommended, I also had to rename all the customModule properties in my Storyboard to match the new name, and this has to be case sensitive.

If your data is already serialized:

a) send a JSON response

public function someAction()
{
    $response = new Response();
    $response->setContent(file_get_contents('path/to/file'));
    $response->headers->set('Content-Type', 'application/json');
    return $response;
}

b) send a JSONP response (with callback)

public function someAction()
{
    $response = new Response();
    $response->setContent('/**/FUNCTION_CALLBACK_NAME(' . file_get_contents('path/to/file') . ');');
    $response->headers->set('Content-Type', 'text/javascript');
    return $response;
}

If your data needs be serialized:

c) send a JSON response

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    return $response;
}

d) send a JSONP response (with callback)

public function someAction()
{
    $response = new JsonResponse();
    $response->setData([some array]);
    $response->setCallback('FUNCTION_CALLBACK_NAME');
    return $response;
}

e) use groups in Symfony 3.x.x

Create groups inside your Entities

<?php

namespace Mindlahus;

use Symfony\Component\Serializer\Annotation\Groups;

/**
 * Some Super Class Name
 *
 * @ORM    able("table_name")
 * @ORM\Entity(repositoryClass="SomeSuperClassNameRepository")
 * @UniqueEntity(
 *  fields={"foo", "boo"},
 *  ignoreNull=false
 * )
 */
class SomeSuperClassName
{
    /**
     * @Groups({"group1", "group2"})
     */
    public $foo;
    /**
     * @Groups({"group1"})
     */
    public $date;

    /**
     * @Groups({"group3"})
     */
    public function getBar() // is* methods are also supported
    {
        return $this->bar;
    }

    // ...
}

Normalize your Doctrine Object inside the logic of your application

<?php

use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Serializer\Mapping\Factory\ClassMetadataFactory;
// For annotations
use Doctrine\Common\Annotations\AnnotationReader;
use Symfony\Component\Serializer\Mapping\Loader\AnnotationLoader;
use Symfony\Component\Serializer\Serializer;
use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;
use Symfony\Component\Serializer\Encoder\JsonEncoder;

...

$repository = $this->getDoctrine()->getRepository('Mindlahus:SomeSuperClassName');
$SomeSuperObject = $repository->findOneById($id);

$classMetadataFactory = new ClassMetadataFactory(new AnnotationLoader(new AnnotationReader()));
$encoder = new JsonEncoder();
$normalizer = new ObjectNormalizer($classMetadataFactory);
$callback = function ($dateTime) {
    return $dateTime instanceof \DateTime
        ? $dateTime->format('m-d-Y')
        : '';
};
$normalizer->setCallbacks(array('date' => $callback));
$serializer = new Serializer(array($normalizer), array($encoder));
$data = $serializer->normalize($SomeSuperObject, null, array('groups' => array('group1')));

$response = new Response();
$response->setContent($serializer->serialize($data, 'json'));
$response->headers->set('Content-Type', 'application/json');
return $response;

sample code is here ,its very easy

LayoutParams params1 = (LayoutParams)twoLetter.getLayoutParams();//twoletter-imageview
                params1.height = 70;
                params1.setMargins(0, 210, 0, 0);//top margin -210 here
                twoLetter.setLayoutParams(params1);//setting layout params
                twoLetter.setImageResource(R.drawable.oo);

Alternative syntax using the -Not operator and depending on your preference for readability:

if( -Not (Test-Path -Path $TARGETDIR ) )
{
    New-Item -ItemType directory -Path $TARGETDIR
}

Before making the npm build,
1) Go to your React project root folder and open package.json.
2) Add "homepage" attribute to package.json

• if you want to provide absolute path

  "homepage": "http://hostName.com/appLocation",
  "name": "react-app",
  "version": "1.1.0",
  

• if you want to provide relative path

  "homepage": "./",
  "name": "react-app",
  

  Using relative path method may warn a syntax validation error in your IDE. But the build is made without any errors during compilation.

3) Save the package.json , and in terminal run npm run-script build
4) Copy the contents of build/ folder to your server directory.

PS: It is easy to use relative path method if you want to change the build file location in your server frequently.

You need to use a <br> because your Content-Type is text/html.

It works without the Content-Type header because then your e-mail will be interpreted as plain text. If you really want to use \n you should use Content-Type: text/plain but then you'll lose any markup.

Also check out similar question here.

Yes, it is very Simple. Just Put your Code Inside this:

<androidx.core.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="match_parent">

//YOUR CODE

</androidx.core.widget.NestedScrollView>

I had issues getting this to work on Windows 7. It seemed to ignore the first argument I passed in so I used binPath= "C:\path\to\service.exe -bogusarg -realarg1 -realarg2" and it worked.

You can also use colnames instead of names if you have data.frame or matrix

Quite often the issue is a non-breaking space - CHAR(160) - especially from Web text sources -that CLEAN can't remove, so I would go a step further than this and try a formula like this which replaces any non-breaking spaces with a standard one

=TRIM(CLEAN(SUBSTITUTE(A1,CHAR(160)," ")))

Ron de Bruin has an excellent post on tips for cleaning data here

You can also remove the CHAR(160) directly without a workaround formula by

• Edit .... Replace your selected data,
• in Find What hold ALT and type 0160 using the numeric keypad
• Leave Replace With as blank and select Replace All

There is an open source common resource grep tool crgrep which searches within PDF files but also other resources like content nested in archives, database tables, image meta-data, POM file dependencies and web resources - and combinations of these including recursive search.

The full description under the Files tab pretty much covers what the tool supports.

I developed crgrep as an opensource tool.

I was wraped it with <> </> as a parent when I changed it to normal , div , its worked fine

use base_url()

echo $baseurl=base_url();

if you need to pass url to a function then use site_url()

 echo site_url('controller/function');

if you need the root path then FCPATH..

echo FCPATH;

Take at this videos for more details about Indexing

Simple Indexing You can create a unique index on a table. A unique index means that two rows cannot have the same index value. Here is the syntax to create an Index on a table

CREATE UNIQUE INDEX index_name
ON table_name ( column1, column2,...);

You can use one or more columns to create an index. For example, we can create an index on tutorials_tbl using tutorial_author.

CREATE UNIQUE INDEX AUTHOR_INDEX
ON tutorials_tbl (tutorial_author)

You can create a simple index on a table. Just omit UNIQUE keyword from the query to create simple index. Simple index allows duplicate values in a table.

If you want to index the values in a column in descending order, you can add the reserved word DESC after the column name.

mysql> CREATE UNIQUE INDEX AUTHOR_INDEX
ON tutorials_tbl (tutorial_author DESC)

Dir seems to be very fast.

Sub LoopThroughFiles()
    Dim MyObj As Object, MySource As Object, file As Variant
   file = Dir("c:\testfolder\")
   While (file <> "")
      If InStr(file, "test") > 0 Then
         MsgBox "found " & file
         Exit Sub
      End If
     file = Dir
  Wend
End Sub

The answers above are correct, and what I'd consider the "best" answers. But just to be as complete as possible, you can also do this directly in CF using queryAddColumn.

See http://www.cfquickdocs.com/cf9/#queryaddcolumn

Again, it's more efficient to do it at the database level... but it's good to be aware of as many alternatives as possible (IMO, of course) :)

You can download the required files from the Microsoft website or online or reinstall the Visual studio 2012 to fix this.

Internet Explorer 9 and lower : You could use conditional comments to load an IE-specific stylesheet for any version (or combination of versions) that you wanted to specifically target.like below using external stylesheet.

<!--[if IE]>
  <link rel="stylesheet" type="text/css" href="all-ie-only.css" />
<![endif]-->

However, beginning in version 10, conditional comments are no longer supported in IE.

Internet Explorer 10 & 11 : Create a media query using -ms-high-contrast, in which you place your IE 10 and 11-specific CSS styles. Because -ms-high-contrast is Microsoft-specific (and only available in IE 10+), it will only be parsed in Internet Explorer 10 and greater.

@media all and (-ms-high-contrast: none), (-ms-high-contrast: active) {
     /* IE10+ CSS styles go here */
}

Microsoft Edge 12 : Can use the @supports rule Here is a link with all the info about this rule

@supports (-ms-accelerator:true) {
  /* IE Edge 12+ CSS styles go here */ 
}

Inline rule IE8 detection

I have 1 more option but it is only detect IE8 and below version.

  /* For IE css hack */
  margin-top: 10px\9 /* apply to all ie from 8 and below */
  *margin-top:10px;  /* apply to ie 7 and below */
  _margin-top:10px; /* apply to ie 6 and below */

As you specefied for embeded stylesheet. I think you need to use media query and condition comment for below version.

After inspecting closely, looks like both of you are using closure.

In your friends case, i is accessed inside anonymous function 1 and i2 is accessed in anonymous function 2 where the console.log is present.

In your case you are accessing i2 inside anonymous function where console.log is present. Add a debugger; statement before console.log and in chrome developer tools under "Scope variables" it will tell under what scope the variable is.

Please set your form action attribute as below it will solve your problem.

<form name="addProductForm" id="addProductForm" action="javascript:;" enctype="multipart/form-data" method="post" accept-charset="utf-8">

jQuery code:

$(document).ready(function () {
    $("#addProductForm").submit(function (event) {

        //disable the default form submission
        event.preventDefault();
        //grab all form data  
        var formData = $(this).serialize();

        $.ajax({
            url: 'addProduct.php',
            type: 'POST',
            data: formData,
            async: false,
            cache: false,
            contentType: false,
            processData: false,
            success: function () {
                alert('Form Submitted!');
            },
            error: function(){
                alert("error in ajax form submission");
            }
        });

        return false;
    });
});

On Linux, I often use curl with the --head parameter. It is available for several operating systems, including Windows.

[edit] related to the answer below, gknw.net is currently down as of February 23 2012. Check curl.haxx.se for updated info.

Solution for Windows/msys git

After reading the answers, I discovered a simpler way that involves changing only one file.

1. Create a batch file to invoke your diff program, with argument 2 and 5. This file must be somewhere in your path. (If you don't know where that is, put it in c:\windows). Call it, for example, "gitdiff.bat". Mine is:

   @echo off
   REM This is gitdiff.bat
   "C:\Program Files\WinMerge\WinMergeU.exe" %2 %5
   

2. Set the environment variable to point to your batch file. For example:GIT_EXTERNAL_DIFF=gitdiff.bat. Or through powershell by typing git config --global diff.external gitdiff.bat.

   It is important to not use quotes, or specify any path information, otherwise it won't work. That's why gitdiff.bat must be in your path.

Now when you type "git diff", it will invoke your external diff viewer.

var cubes = [["string", "string"], ["string", "string"]];

for(var i = 0; i < cubes.length; i++) {
    for(var j = 0; j < cubes[i].length; j++) {
        console.log(cubes[i][j]);
    }
}

Please try following

if ([ $dateR -ge 234 ] && [ $dateR -lt 238 ]) || ([ $dateR -ge 834 ] && [ $dateR -lt 838 ]) || ([ $dateR -ge 1434 ] && [ $dateR -lt 1438 ]) || ([ $dateR -ge 2034 ] && [ $dateR -lt 2038 ]) ;
then
    echo "WORKING"
else
    echo "Out of range!"

A POSIX compliant answer. Notice the use of /bin/sh instead of /bin/bash. (It does work with bash, but it does not require bash.)

#!/bin/sh
stty -echo
printf "Password: "
read PASSWORD
stty echo
printf "\n"

Compiling the last answers into one:

If you're on Windows, use chocolatey:

choco install ffmpeg

If you are on Mac, use Brew:

brew install ffmpeg

If you are on a Debian Linux distribution, use apt:

sudo apt-get install ffmpeg

And make sure Youtube-dl is updated:

youtube-dl -U

Also, the best practice of moving your <script></script> to the bottom of the html file fixes this too.

Here is a version of @adabyron's answer that prevents the leaky EventArgs abstraction.

First, the modified EventToCommandBehavior class (now a generic abstract class and formatted with ReSharper code cleanup). Note the new GetCommandParameter virtual method and its default implementation:

public abstract class EventToCommandBehavior<TEventArgs> : Behavior<FrameworkElement>
    where TEventArgs : EventArgs
{
    public static readonly DependencyProperty EventProperty = DependencyProperty.Register("Event", typeof(string), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(null, OnEventChanged));
    public static readonly DependencyProperty CommandProperty = DependencyProperty.Register("Command", typeof(ICommand), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(null));
    public static readonly DependencyProperty PassArgumentsProperty = DependencyProperty.Register("PassArguments", typeof(bool), typeof(EventToCommandBehavior<TEventArgs>), new PropertyMetadata(false));
    private Delegate _handler;
    private EventInfo _oldEvent;

    public string Event
    {
        get { return (string)GetValue(EventProperty); }
        set { SetValue(EventProperty, value); }
    }

    public ICommand Command
    {
        get { return (ICommand)GetValue(CommandProperty); }
        set { SetValue(CommandProperty, value); }
    }

    public bool PassArguments
    {
        get { return (bool)GetValue(PassArgumentsProperty); }
        set { SetValue(PassArgumentsProperty, value); }
    }

    protected override void OnAttached()
    {
        AttachHandler(Event);
    }

    protected virtual object GetCommandParameter(TEventArgs e)
    {
        return e;
    }

    private void AttachHandler(string eventName)
    {
        _oldEvent?.RemoveEventHandler(AssociatedObject, _handler);

        if (string.IsNullOrEmpty(eventName))
        {
            return;
        }

        EventInfo eventInfo = AssociatedObject.GetType().GetEvent(eventName);

        if (eventInfo != null)
        {
            MethodInfo methodInfo = typeof(EventToCommandBehavior<TEventArgs>).GetMethod("ExecuteCommand", BindingFlags.Instance | BindingFlags.NonPublic);

            _handler = Delegate.CreateDelegate(eventInfo.EventHandlerType, this, methodInfo);
            eventInfo.AddEventHandler(AssociatedObject, _handler);
            _oldEvent = eventInfo;
        }
        else
        {
            throw new ArgumentException($"The event '{eventName}' was not found on type '{AssociatedObject.GetType().FullName}'.");
        }
    }

    private static void OnEventChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var behavior = (EventToCommandBehavior<TEventArgs>)d;

        if (behavior.AssociatedObject != null)
        {
            behavior.AttachHandler((string)e.NewValue);
        }
    }

    // ReSharper disable once UnusedMember.Local
    // ReSharper disable once UnusedParameter.Local
    private void ExecuteCommand(object sender, TEventArgs e)
    {
        object parameter = PassArguments ? GetCommandParameter(e) : null;

        if (Command?.CanExecute(parameter) == true)
        {
            Command.Execute(parameter);
        }
    }
}

Next, an example derived class that hides DragCompletedEventArgs. Some people expressed concern about leaking the EventArgs abstraction into their view model assembly. To prevent this, I created an interface that represents the values we care about. The interface can live in the view model assembly with the private implementation in the UI assembly:

// UI assembly
public class DragCompletedBehavior : EventToCommandBehavior<DragCompletedEventArgs>
{
    protected override object GetCommandParameter(DragCompletedEventArgs e)
    {
        return new DragCompletedArgs(e);
    }

    private class DragCompletedArgs : IDragCompletedArgs
    {
        public DragCompletedArgs(DragCompletedEventArgs e)
        {
            Canceled = e.Canceled;
            HorizontalChange = e.HorizontalChange;
            VerticalChange = e.VerticalChange;
        }

        public bool Canceled { get; }
        public double HorizontalChange { get; }
        public double VerticalChange { get; }
    }
}

// View model assembly
public interface IDragCompletedArgs
{
    bool Canceled { get; }
    double HorizontalChange { get; }
    double VerticalChange { get; }
}

Cast the command parameter to IDragCompletedArgs, similar to @adabyron's answer.

VAR=$(scan)

Exactly the same way as for programs.

Chrome 11 spits out the following in its debugger:

[Error] GET http://www.mypicx.com/images/logo.jpg undefined (undefined)

It looks like that hosting service is using some funky dynamic system that is preventing these browsers from fetching it correctly. (Instead it tries to fetch the default base image, which is problematically a jpeg.) Could you just upload another copy of the image elsewhere? I would expect it to be the easiest solution by a long mile.

Edit: See what happens in Chrome when you place the image using normal <img> tags ;)

Interesting question!

capitalize transforms every first letter of a word to uppercase, but it does not transform the other letters to lowercase. Not even the :first-letter pseudo-class will cut it (because it applies to the first letter of each element, not each word), and I can't see a way of combining lowercase and capitalize to get the desired outcome.

So as far as I can see, this is indeed impossible to do with CSS.

@Harmen shows good-looking PHP and jQuery workarounds in his answer.

You can do it in this way with Swift 3.0:

let date = Date()
let calendar = Calendar.current
let components = calendar.dateComponents([.year, .month, .day], from: date)

let year =  components.year
let month = components.month
let day = components.day

print(year)
print(month)
print(day)

You have 3 options:

1) Get default value

dt = datetime??DateTime.Now;

it will assign DateTime.Now (or any other value which you want) if datetime is null

2) Check if datetime contains value and if not return empty string

if(!datetime.HasValue) return "";
dt = datetime.Value;

3) Change signature of method to

public string ConvertToPersianToShow(DateTime  datetime)

It's all because DateTime? means it's nullable DateTime so before assigning it to DateTime you need to check if it contains value and only then assign.

I needed to completely remove the Bootstrap responsive feature, i ended up overriding the behavior with the following snippet:

.container {
    width: 960px !important;
}

@media (min-width: 1px) {
  .container {
    max-width: 940px;
  }
  .col-lg-1,
  .col-lg-2,
[...]

Full snippet: https://gist.github.com/ivanminutillo/8557293

If you don't need the user instance on site (as I did), you can do it with

User.objects.filter(pk=userId, groups__name='Editor').exists()

This will produce only one request to the database and return a boolean.

I am in a corporate setting and was attempting a simple git pull after a recent change in password.

I got: remote: Invalid username or password.

Interestingly, the following did not work: git config --global --unset credential.helper

I use Windows-7, so, I went to control panel -> Credential Manager -> Generic Credentials.

From the credential manager list, delete the line items corresponding to git.

After the deletion, come back to gitbash and git pull should prompt the dialog for you to enter your credentials.

console.log() calls process.stdout.write with formatted output. See format() in console.js for the implementation.

Currently (v0.10.ish):

Console.prototype.log = function() {
  this._stdout.write(util.format.apply(this, arguments) + '\n');
};

In kotlin this can be implemented easily as follows:

/**
 * If android version is Kitkat or above, users can change default sms application.
 * This method will get default sms app and start default sms app.
 */
private fun openSMS() {
    val message = "message here"
    val phone = "255754......." //255 Tanzania code.

    val uri = Uri.parse("smsto:+$phone")
    val intent = Intent(Intent.ACTION_SENDTO, uri)

    with(intent) {
        putExtra("address", "+$phone")
        putExtra("sms_body", message)
    }

    when {
        Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT -> {
            //Getting the default sms app.
            val defaultSmsPackageName = Telephony.Sms.getDefaultSmsPackage(context)

            // Can be null in case that there is no default, then the user would be able to choose
            // any app that support this intent.
            if (defaultSmsPackageName != null) intent.setPackage(defaultSmsPackageName)

            startActivity(intent)
        }
        else -> startActivity(intent)
    }
}

This is modified answer of @mustafasevgi

The problems is that dropboxes don't work the same as listboxes, at least the way ASP.NET MVC2 design expects: A dropbox allows only zero or one values, as listboxes can have a multiple value selection. So, being strict with HTML, that value shouldn't be in the option list as "selected" flag, but in the input itself.

See the following example:

<select id="combo" name="combo" value="id2">
  <option value="id1">This is option 1</option>
  <option value="id2" selected="selected">This is option 2</option>
  <option value="id3">This is option 3</option>
</select>

<select id="listbox" name="listbox" multiple>
  <option value="id1">This is option 1</option>
  <option value="id2" selected="selected">This is option 2</option>
  <option value="id3">This is option 3</option>
</select>

The combo has the option selected, but also has its value attribute set. So, if you want ASP.NET MVC2 to render a dropbox and also have a specific value selected (i.e., default values, etc.), you should give it a value in the rendering, like this:

// in my view             
<%=Html.DropDownList("UserId", selectListItems /* (SelectList)ViewData["UserId"]*/, new { @Value = selectedUser.Id } /* Your selected value as an additional HTML attribute */)%>

I did want to obmit a old big history and start from a fresh commit i choosed to:

rsync -a --exclude '.git' old-repo/ new-repo/
cd new-repo 
git push 

when now old-repo changes i can apply the patches to the new-repo to rebase them on the new-repo.

If you are asking whether there's shorthand version of operator .. - no there isn't. You cannot write a ..= b. You'll have to type it in full: filename = filename .. ".tmp"

Its because the email address which is being sent is blank. see those empty brackets? that means the email address is not being put in the $address of the swiftmailer function.

In a new PHP7 there is a finally a support for a cryptographically secure pseudo-random integers.

int random_int ( int $min , int $max )

random_int — Generates cryptographically secure pseudo-random integers

which basically makes previous answers obsolete.

In case you have composite primary key, do like this- ALTER TABLE table_name DROP PRIMARY KEY,ADD PRIMARY KEY (col_name1, col_name2);

We're trying this on a short list that does not do any view recycling. So far so good.

XML:

<RitalinLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
  <ListView
      android:id="@+id/cart_list"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbarStyle="outsideOverlay"
      />
</RitalinLayout>

Java:

/**
 * It helps you keep focused.
 *
 * For use as a parent of {@link android.widget.ListView}s that need to use EditText
 * children for inline editing.
 */
public class RitalinLayout extends FrameLayout {
  View sticky;

  public RitalinLayout(Context context, AttributeSet attrs) {
    super(context, attrs);

    ViewTreeObserver vto = getViewTreeObserver();

    vto.addOnGlobalFocusChangeListener(new ViewTreeObserver.OnGlobalFocusChangeListener() {
      @Override public void onGlobalFocusChanged(View oldFocus, View newFocus) {
        if (newFocus == null) return;

        View baby = getChildAt(0);

        if (newFocus != baby) {
          ViewParent parent = newFocus.getParent();
          while (parent != null && parent != parent.getParent()) {
            if (parent == baby) {
              sticky = newFocus;
              break;
            }
            parent = parent.getParent();
          }
        }
      }
    });

    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override public void onGlobalLayout() {
        if (sticky != null) {
          sticky.requestFocus();
        }
      }
    });
  }
}

if you use isset like the answer posted already by singles, just make sure there is a bracket at the end like so:
$query_age = (isset($_GET['query_age']) ? $_GET['query_age'] : null);

As you run your spark app on top of HDFS, according to Sandy Ryza

I’ve noticed that the HDFS client has trouble with tons of concurrent threads. A rough guess is that at most five tasks per executor can achieve full write throughput, so it’s good to keep the number of cores per executor below that number.

So I believe that your first configuration is slower than third one is because of bad HDFS I/O throughput

My solution if you work with the Trunk/ and Release/ workflow:

Right click on Trunk/ which you will be creating your Branch from:

Select Branch/Tag:

Type in location of your new branch, commit message, and any externals (if your repository has them):

I'm not so thrilled about the InetAddress.getLocalHost().getHostName() solution that you can find so many places on the Internet and indeed also here. That method will get you the hostname as seen from a network perspective. I can see two problems with this:

1. What if the host has multiple network interfaces ? The host may be known on the network by multiple names. The one returned by said method is indeterminate afaik.

2. What if the host is not connected to any network and has no network interfaces ?

All OS'es that I know of have the concept of naming a node/host irrespective of network. Sad that Java cannot return this in an easy way. This would be the environment variable COMPUTERNAME on all versions of Windows and the environment variable HOSTNAME on Unix/Linux/MacOS (or alternatively the output from host command hostname if the HOSTNAME environment variable is not available as is the case in old shells like Bourne and Korn).

I would write a method that would retrieve (depending on OS) those OS vars and only as a last resort use the InetAddress.getLocalHost().getHostName() method. But that's just me.

UPDATE (Unices)

As others have pointed out the HOSTNAME environment variable is typically not available to a Java application on Unix/Linux as it is not exported by default. Hence not a reliable method unless you are in control of the clients. This really sucks. Why isn't there a standard property with this information?

Alas, as far as I can see the only reliable way on Unix/Linux would be to make a JNI call to gethostname() or to use Runtime.exec() to capture the output from the hostname command. I don't particularly like any of these ideas but if anyone has a better idea I'm all ears. (update: I recently came across gethostname4j which seems to be the answer to my prayers).

Long read

I've created a long explanation in another answer on another post. In particular you may want to read it because it attempts to establish some terminology, gives concrete examples of when the InetAddress.getLocalHost().getHostName() solution will fail, and points to the only safe solution that I know of currently, namely gethostname4j.

It's sad that Java doesn't provide a method for obtaining the computername. Vote for JDK-8169296 if you are able to.

Do not set cnopts.hostkeys = None (as the second most upvoted answer shows), unless you do not care about security. You lose a protection against Man-in-the-middle attacks by doing so.

Use CnOpts.hostkeys (returns HostKeys) to manage trusted host keys.

cnopts = pysftp.CnOpts(knownhosts='known_hosts')

with pysftp.Connection(host, username, password, cnopts=cnopts) as sftp:

where the known_hosts contains a server public key(s)] in a format like:

example.com ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...

If you do not want to use an external file, you can also use

from base64 import decodebytes
# ...

keydata = b"""AAAAB3NzaC1yc2EAAAADAQAB..."""
key = paramiko.RSAKey(data=decodebytes(keydata))
cnopts = pysftp.CnOpts()
cnopts.hostkeys.add('example.com', 'ssh-rsa', key)

with pysftp.Connection(host, username, password, cnopts=cnopts) as sftp:

Though as of pysftp 0.2.9, this approach will issue a warning, what seems like a bug:
"Failed to load HostKeys" warning while connecting to SFTP server with pysftp

An easy way to retrieve the host key in the needed format is using OpenSSH ssh-keyscan:

$ ssh-keyscan example.com
# example.com SSH-2.0-OpenSSH_5.3
example.com ssh-rsa AAAAB3NzaC1yc2EAAAADAQAB...

(due to a bug in pysftp, this does not work, if the server uses non-standard port – the entry starts with [example.com]:port + beware of redirecting ssh-keyscan to a file in PowerShell)

You can also make the application do the same automatically:
Use Paramiko AutoAddPolicy with pysftp
(It will automatically add host keys of new hosts to known_hosts, but for known host keys, it will not accept a changed key)

Though for an absolute security, you should not retrieve the host key remotely, as you cannot be sure, if you are not being attacked already.

See my article Where do I get SSH host key fingerprint to authorize the server?
It's for my WinSCP SFTP client, but most information there is valid in general.

If you need to verify the host key using its fingerprint only, see Python - pysftp / paramiko - Verify host key using its fingerprint.

Array functional way:

   array.enumerated().filter { $0.offset < limit }.map { $0.element }

ranged:

 array.enumerated().filter { $0.offset >= minLimit && $0.offset < maxLimit }.map { $0.element }

The advantage of this method is such implementation is safe.

This is a quick and simple add of a named tab to the current worksheet:

Sheets.Add.Name = "Tempo"

You can write like

UILabel *reviews = [[UILabel alloc]initWithFrame:CGRectMake(14, 13,270,30)];//Set frame
reviews.numberOfLines=0;
reviews.textAlignment = UITextAlignmentLeft;
reviews.font = [UIFont fontWithName:@"Arial Rounded MT Bold" size:12];
reviews.textColor=[UIColor colorWithRed:0.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:0.8]; 
reviews.backgroundColor=[UIColor clearColor];

You can calculate number of lines like that

CGSize maxlblSize = CGSizeMake(270,9999);
CGSize totalSize = [reviews.text sizeWithFont:reviews.font 
              constrainedToSize:maxlblSize lineBreakMode:reviews.lineBreakMode];

CGRect newFrame =reviews.frame;
newFrame.size.height = totalSize.height;
reviews.frame = newFrame;

CGFloat reviewlblheight = totalSize.height;

int lines=reviewlblheight/12;//12 is the font size of label

UILabel *lbl=[[UILabel alloc]init];
lbl.frame=CGRectMake(140,220 , 100, 25);//set frame as your requirement
lbl.font=[UIFont fontWithName:@"Arial" size:20];
[lbl setAutoresizingMask:UIViewContentModeScaleAspectFill];
[lbl setLineBreakMode:UILineBreakModeClip];
lbl.adjustsFontSizeToFitWidth=YES;//This is main for shrinking font
lbl.text=@"HelloHelloHello";

Hope this will help you :-) waiting for your reply

Please use [::1] instead of localhost, and make sure that the port is correct, and put the port inside the link.

const request = require('request');

   let json = {

        json: json
    };
    request(options, function (error, response, body) {
        if (error) {
            console.error("httpRequests : error " + error);
        }
        if (response) {

The accepted answer of using npm-install-peers did not work, nor removing node_modules and rebuilding. The answer to run

npm install --save-dev @xxxxx/xxxxx@latest

for each one, with the xxxxx referring to the exact text in the peer warning, worked. I only had four warnings, if I had a dozen or more as in the question, it might be a good idea to script the commands.

If you're using data binding, then you need to use the ContentRendered event.

For the code below, the Header is NULL when the Loaded event is raised. However, Header gets its value when the ContentRendered event is raised.

<MenuItem Header="{Binding NewGame_Name}" Command="{Binding NewGameCommand}" />

Here is a friendly piece of advice. Use something like Chrome Developer Tools or Firebug for Firefox to inspect your Ajax calls and results.

You may also want to invest some time in understanding a helper library like Underscore, which complements jQuery and gives you 60+ useful functions for manipulating data objects with JavaScript.

If you are using the distro go, you should point to where the include files are, for example:

$ rpm -ql golang | grep include
/usr/lib/golang/include

(This is for Fedora 20)

String.format("%0d.%02d", d / 100, d % 100);

You can change the tool used by git mergetool by passing git mergetool -t=<tool> or --tool=<tool>. To change the default (from vimdiff) use git config merge.tool <tool>.

For those coming here from Google, and for whom the previous answers do not solve the mystery...

If you use XHR to make a server call, but do not return a response, this error will occur.

Example (from Nodejs/React but could equally be js/php):

App.tsx

const handleClickEvent = () => {
    fetch('/routeInAppjs?someVar=someValue&nutherVar=summat_else', {
        method: 'GET',
        mode: 'same-origin',
        credentials: 'include',
        headers: {
          'content-type': 'application/json',
          dataType: 'json',
        },
    }).then((response) => {
        console.log(response)
    });
}

App.js

app.route('/getAllPublicDatasheets').get(async function (req, res) {
    const { someVar, nutherVar } = req.query;
    console.log('Ending here without a return...')
});

Console.log will here report:

Failed to show response data

To fix, add the return response to bottom of your route (server-side):

res.json('Adding this below the console.log in App.js route will solve it.');

I'd echo roughly the same point GMan made: depending on the type of use, std::map can be (and often is) faster than std::tr1::unordered_map (using the implementation included in VS 2008 SP1).

There are a few complicating factors to keep in mind. For example, in std::map, you're comparing keys, which means you only ever look at enough of the beginning of a key to distinguish between the right and left sub-branches of the tree. In my experience, nearly the only time you look at an entire key is if you're using something like int that you can compare in a single instruction. With a more typical key type like std::string, you often compare only a few characters or so.

A decent hash function, by contrast, always looks at the entire key. IOW, even if the table lookup is constant complexity, the hash itself has roughly linear complexity (though on the length of the key, not the number of items). With long strings as keys, an std::map might finish a search before an unordered_map would even start its search.

Second, while there are several methods of resizing hash tables, most of them are pretty slow -- to the point that unless lookups are considerably more frequent than insertions and deletions, std::map will often be faster than std::unordered_map.

Of course, as I mentioned in the comment on your previous question, you can also use a table of trees. This has both advantages and disadvantages. On one hand, it limits the worst case to that of a tree. It also allows fast insertion and deletion, because (at least when I've done it) I've used a fixed-size of table. Eliminating all table resizing allows you to keep your hash table a lot simpler and typically faster.

One other point: the requirements for hashing and tree-based maps are different. Hashing obviously requires a hash function, and an equality comparison, where ordered maps require a less-than comparison. Of course the hybrid I mentioned requires both. Of course, for the common case of using a string as the key, this isn't really a problem, but some types of keys suit ordering better than hashing (or vice versa).

Take a look at the $_GET and $_REQUEST superglobals. Something like the following would work for your example:

$start = $_GET['start'];
$limit = $_GET['limit'];

EDIT

According to this post in the laravel forums, you need to use Input::get(), e.g.,

$start = Input::get('start');
$limit = Input::get('limit');

See also: http://laravel.com/docs/input#input

If you had caught the error, you would have seen this:

jsonString, err := json.Marshal(datas)
fmt.Println(err)

// [] json: unsupported type: map[int]main.Foo

The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa.

See this post for more details: https://stackoverflow.com/a/24284721/2679935

If you are working on Windows OS, you can use OS module to get it:

import os
cmd = 'wmic desktopmonitor get screenheight, screenwidth'
size_tuple = tuple(map(int,os.popen(cmd).read().split()[-2::]))

It will return a tuple (Y,X) where Y is the vertical size and X is the horizontal size. This code works on Python 2 and Python 3

I am not very good in grep. But your problem can be solved using AWK command. Just see

awk '/select/,/from/' *.sql

The above code will result from first occurence of select till first sequence of from. Now you need to verify whether returned statements are having customername or not. For this you can pipe the result. And can use awk or grep again.

I only want to cover second point of the question that is related to performance, because no body else has covered this. Select Into is a lot more faster than insert into, when it comes to tables with large datasets. I prefer select into when I have to read a very large table. insert into for a table with 10 million rows may take hours while select into will do this in minutes, and as for as losing indexes on new table is concerned you can recreate the indexes by query and can still save a lot more time when compared to insert into.

About prototype bean(s) :

The client code must clean up prototype-scoped objects and release expensive resources that the prototype bean(s) are holding. To get the Spring container to release resources held by prototype-scoped beans, try using a custom bean post-processor, which holds a reference to beans that need to be cleaned up.

Eclipse freezing at startup - before loading workspace very good answer on this post. repeating the answer that worked for me

In your workspace directory perform the following steps:

cd .metadata/.plugins

mv org.eclipse.core.resources org.eclipse.core.resources.bak

Start eclipse. (It should show an error message or an empty workspace because no project is found.)

Close all open editors tabs.

Exit eclipse.

rm -rf org.eclipse.core.resources (Delete the newly created directory.)

mv org.eclipse.core.resources.bak/ org.eclipse.core.resources (Restore the original directory.)

Start eclipse and start working. :-)

If you set a session in php5, then try to read it on a php4 page, it might not look in the correct place! Make the pages the same php version or set the session_path.

ls -lR is to display all files, directories and sub directories of the current directory ls -lR | more is used to show all the files in a flow.

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

In my case it was the use of the call_command module that posed a problem.

All other answers solves the problem and my answer works the same way as the others, but just on a more didactically way (this works on MySQL... don't know other SQL servers):

INSERT INTO table1 SET 
  stringColumn  = 'A String', 
  numericColumn = 5, 
  selectColumn  = (SELECT idTable2 FROM table2 WHERE ...);

You can refer the MySQL documentation: INSERT Syntax

Extract characters from a string:

var str = "Hello world!";
var res = str.substring(1,4);

The result of res will be:

ell

$('.dep_buttons').mouseover(function(){
    $(this).text().substring(0,25);
    if($(this).text().length > 30) {
        $(this).stop().animate({height:"150px"},150);
    }
    $(".dep_buttons").mouseout(function(){
        $(this).stop().animate({height:"40px"},150);
    });
});

Try to use the argument: -sysdir <Your_SDK_DIR> and then check whether the error message displayed.

Check out these clip you will find out the reason:

if (avdName) {
    if (!isCpuArchSupportedByRanchu(avdArch)) {
        APANIC("CPU Architecture '%s' is not supported by the QEMU2 emulator, (the classic engine is deprecated!)",
               avdArch);
    }
    std::string systemPath = getAvdSystemPath(avdName, sysDir);
    if (systemPath.empty()) {
        const char* env = getenv("ANDROID_SDK_ROOT");
        if (!env || !env[0]) {
            APANIC("Cannot find AVD system path. Please define "
                   "ANDROID_SDK_ROOT\n");
        } else {
            APANIC("Broken AVD system path. Check your ANDROID_SDK_ROOT "
                   "value [%s]!\n",
                   env);
        }
    }
}

Then if you see emulator: ERROR: can't find SDK installation directory, please check this solution. Android emulator errors with "emulator: ERROR: can't find SDK installation directory"

For a list of full path names I prefer this version to the other solutions here:

def listdirs(dir):
    return [os.path.join(os.path.join(dir, x)) for x in os.listdir(dir) 
        if os.path.isdir(os.path.join(dir, x))]

sys.exit is the canonical way to exit.

Internally sys.exit just raises SystemExit. However, calling sys.exitis more idiomatic than raising SystemExit directly.

os.exit is a low-level system call that exits directly without calling any cleanup handlers.

quit and exit exist only to provide an easy way out of the Python prompt. This is for new users or users who accidentally entered the Python prompt, and don't want to know the right syntax. They are likely to try typing exit or quit. While this will not exit the interpreter, it at least issues a message that tells them a way out:

>>> exit
Use exit() or Ctrl-D (i.e. EOF) to exit
>>> exit()
$

This is essentially just a hack that utilizes the fact that the interpreter prints the __repr__ of any expression that you enter at the prompt.

SELECT CONVERT(VARCHAR,@date,112) + 
LEFT(REPLACE(CONVERT(VARCHAR,@date,114),':',''),6)

You can do by maintaining the state as below:

$('#user_button').on('click',function(){
    if($(this).attr('data-click-state') == 1) {
        $(this).attr('data-click-state', 0);
        $(this).css('background-color', 'red')
      }
    else {
      $(this).attr('data-click-state', 1);
      $(this).css('background-color', 'orange')
    }
  });

Take a reference from hear codepen example

// this is better suited for expensive object creation/initialization
IEnumerable<Employee> ParseEmployeeTable(DataTable dtEmployees)
{
    var employees = new ConcurrentBag<Employee>();

    Parallel.ForEach(dtEmployees.AsEnumerable(), (dr) =>
    {
        employees.Add(new Employee() 
        {
            _FirstName = dr["FirstName"].ToString(),
            _LastName = dr["Last_Name"].ToString()
        });
    });

    return employees;
}

simply replace

background-image:url(../images/images2.jpg) no-repeat;

with

background:url(../images/images2.jpg)  center;

here's how to replace the same image in all folders in a directory with white instead of transparent:

mogrify -background white -flatten */*.png

Does c# have its own version of the java "synchronized" keyword?

No. In C#, you explicitly lock resources that you want to work on synchronously across asynchronous threads. lock opens a block; it doesn't work on method level.

However, the underlying mechanism is similar since lock works by invoking Monitor.Enter (and subsequently Monitor.Exit) on the runtime. Java works the same way, according to the Sun documentation.

Slightly unrelated, but to remove ^M from the command line using Perl, do this:

perl -p -i -e "s/\r\n/\n/g" file.name

I was able to get it working without putting in the username and password:

conda config --set proxy_servers.https https://address:port

String path = "C:\\Documents and Settings\\Manoj\\Desktop";
path = path.replace("\\", "/");
// or
path = path.replaceAll("\\\\", "/");

• nesting SUBSTITUTE() in a string can be nasty, however, it's always possible to arrange it:

You have to fetch the whole data in the list and then do the iteration as it is a file and will become inefficient otherwise.

private static final Type REVIEW_TYPE = new TypeToken<List<Review>>() {
}.getType();
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
List<Review> data = gson.fromJson(reader, REVIEW_TYPE); // contains the whole reviews list
data.toScreen(); // prints to screen some values

here's a hairy, built in way to get many of the same answers. Note that although python considers "" to be false and all other strings to be true, TCL has a very different idea about things.

>>> import Tkinter
>>> tk = Tkinter.Tk()
>>> var = Tkinter.BooleanVar(tk)
>>> var.set("false")
>>> var.get()
False
>>> var.set("1")
>>> var.get()
True
>>> var.set("[exec 'rm -r /']")
>>> var.get()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.5/lib-tk/Tkinter.py", line 324, in get

A good thing about this is that it is fairly forgiving about the values you can use. It's lazy about turning strings into values, and it's hygenic about what it accepts and rejects(notice that if the above statement were given at a tcl prompt, it would erase the users hard disk).

the bad thing is that it requires that Tkinter be available, which is usually, but not universally true, and more significantly, requires that a Tk instance be created, which is comparatively heavy.

What is considered true or false depends on the behavior of the Tcl_GetBoolean, which considers 0, false, no and off to be false and 1, true, yes and on to be true, case insensitive. Any other string, including the empty string, cause an exception.

use autoplay=0

autoplay takes 2 values.

Values: 0 or 1. Default is 0. Sets whether or not the initial video will autoplay when the player loads.

the important part

autoplay=0&showinfo=0&controls=0

Here is the demo for ur problem FIDDLE

Implement your Dropdown as

<select id = "dropdown" ref = {(input)=> this.menu = input}>
    <option value="N/A">N/A</option>
    <option value="1">1</option>
    <option value="2">2</option>
    <option value="3">3</option>
    <option value="4">4</option>
</select>

Now, to obtain the selected option value of the dropdown menu just use:

let res = this.menu.value;

Simply issuing rm CMakeCache.txt works for me too.

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

before using above code you have to add the gen_validatorv31.js js file

Use the load event:

img = new Image();

img.onload = function(){
  // image  has been loaded
};

img.src = image_url;

Also have a look at:

• Preloading and the JavaScript Image() object

Look at the r.status_code attribute:

if r.status_code == 404:
    # A 404 was issued.

Demo:

>>> import requests
>>> r = requests.get('http://httpbin.org/status/404')
>>> r.status_code
404

If you want requests to raise an exception for error codes (4xx or 5xx), call r.raise_for_status():

>>> r = requests.get('http://httpbin.org/status/404')
>>> r.raise_for_status()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "requests/models.py", line 664, in raise_for_status
    raise http_error
requests.exceptions.HTTPError: 404 Client Error: NOT FOUND
>>> r = requests.get('http://httpbin.org/status/200')
>>> r.raise_for_status()
>>> # no exception raised.

You can also test the response object in a boolean context; if the status code is not an error code (4xx or 5xx), it is considered ‘true’:

if r:
    # successful response

If you want to be more explicit, use if r.ok:.

The method System.Web.UI.Page.RegisterClientScriptBlock has been deprecated for some time (along with the other Page.Register* methods), ever since .NET 2.0 as shown by MSDN.

Instead use the .NET 2.0 Page.ClientScript.Register* methods. - (The ClientScript property expresses an instance of the ClientScriptManager class )

Guessing the problem

If you are saying your JavaScript alert box occurs before the page's content is visibly rendered, and therefore the page remains white (or still unrendered) when the alert box is dismissed by the user, then try using the Page.ClientScript.RegisterStartupScript(..) method instead because it runs the given client-side code when the page finishes loading - and its arguments are similar to what you're using already.

Also check for general JavaScript errors in the page - this is often seen by an error icon in the browser's status bar. Sometimes a JavaScript error will hold up or disturb unrelated elements on the page.

"py -m pip install requests" works fine with Windows and its up gradation. Just change the path after installing Python 3.4 in the command prompt and type in "py -m pip install requests"command prompt. pip install

Another way to do:

First, install these modules: url-loader, file-loader

Using npm: npm install --save-dev url-loader file-loader

Next, add this to your Webpack config:

module: {
    loaders: [
      { test: /\.(png|jpg)$/, loader: 'url-loader?limit=8192' }
    ]
  }

limit: Byte limit to inline files as Data URL

You need to install both modules: url-loader and file-loader

Finally, you can do:

<img src={require('./my-path/images/my-image.png')}/>

You can investigate these loaders further here:

url-loader: https://www.npmjs.com/package/url-loader

file-loader: https://www.npmjs.com/package/file-loader

There's nothing wrong with combining an id and a class on one element, but you shouldn't need to identify it by both for one rule. If you really want to you can do:

#content.sectionA{some rules}

You don't need the div in front of the ID as others have suggested.

In general, CSS rules specific to that element should be set with the ID, and those are going to carry a greater weight than those of just the class. Rules specified by the class would be properties that apply to multiple items that you don't want to change in multiple places anytime you need to adjust.

That boils down to this:

 .sectionA{some general rules here}
 #content{specific rules, and overrides for things in .sectionA}

Make sense?

This command loads class of Oracle jdbc driver to be available for DriverManager instance. After the class is loaded system can connect to Oracle using it. As an alternative you can use registerDriver method of DriverManager and pass it with instance of JDBC driver you need.

if you don' t want to assign a display:none to a css class, the right approach in to append to style, jQuery.Rule do the job.

I some cases you want to apply stiles before the append event of ajax content and fade content after append and this is it!

use this for target path for uploading

<?php
$file_name = $_FILES["csvFile"]["name"];
$target_path = $dir = plugin_dir_path( __FILE__ )."\\upload\\". $file_name;
echo $target_path;
move_uploaded_file($_FILES["csvFile"]["tmp_name"],$target_path. $file_name);
?>

also you can try in your servce to set headers like for example:

...
import { Injectable } from "@angular/core";
import { HttpClient, HttpHeaders, HttpParams } from "@angular/common/http";
...
 @Injectable()
export class MyService {

    private headers: HttpHeaders;


    constructor(private http: HttpClient..) 
    {


        this.headers = new HttpHeaders()
                    .append("Content-Type", "application/json")
                    .append("Accept", "application/json")
                    .append("LanguageCulture", this.headersLanguage)
                    .append("Cache-Control", "no-cache")
                    .append("Pragma", "no-cache")                   
    }
}
....

So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.

While ENV, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args at every build without changing our docker file.

For more details, you can refer this.

Here, Environment.NewLine doesn't worked.

I put a "<br/>" in a string and worked.

Ex:

ltrYourLiteral.Text = "First line.<br/>Second Line.";

This question is not specific to jQuery, but specific to JavaScript in general. The core problem is how to "channel" a variable in embedded functions. This is the example:

var abc = 1; // we want to use this variable in embedded functions

function xyz(){
  console.log(abc); // it is available here!
  function qwe(){
    console.log(abc); // it is available here too!
  }
  ...
};

This technique relies on using a closure. But it doesn't work with this because this is a pseudo variable that may change from scope to scope dynamically:

// we want to use "this" variable in embedded functions

function xyz(){
  // "this" is different here!
  console.log(this); // not what we wanted!
  function qwe(){
    // "this" is different here too!
    console.log(this); // not what we wanted!
  }
  ...
};

What can we do? Assign it to some variable and use it through the alias:

var abc = this; // we want to use this variable in embedded functions

function xyz(){
  // "this" is different here! --- but we don't care!
  console.log(abc); // now it is the right object!
  function qwe(){
    // "this" is different here too! --- but we don't care!
    console.log(abc); // it is the right object here too!
  }
  ...
};

this is not unique in this respect: arguments is the other pseudo variable that should be treated the same way — by aliasing.

if (10 < x || x < 20)

This statement will evaluate true for numbers between 10 and 20. This is a rough equivalent to 10 < x < 20

Your code works, but it uses deprecated methods to do so. You should use the CSS text-align property to do this rather than the align property. Even so, it must be your browser or something else affecting it. Try this demo in Chrome (I had to disable normalize.css to get it to render).

Your question about performance is moot—both functions are very fast. The speed of your code will be determined by what you do with the random numbers.

However it's important you understand the difference in behaviour of those two functions. One does random sampling with replacement, the other does random sampling without replacement.

You are supposed to download the jar files that contain these libraries. Libraries may be used by adding them to the classpath.

For Commons Net you need to download the binary files from Commons Net download page. Then you have to extract the file and add the commons-net-2-2.jar file to some location where you can access it from your application e.g. to /lib.

If you're running your application from the command-line you'll have to define the classpath in the java command: java -cp .;lib/commons-net-2-2.jar myapp. More info about how to set the classpath can be found from Oracle documentation. You must specify all directories and jar files you'll need in the classpath excluding those implicitely provided by the Java runtime. Notice that there is '.' in the classpath, it is used to include the current directory in case your compiled class is located in the current directory.

For more advanced reading, you might want to read about how to define the classpath for your own jar files, or the directory structure of a war file when you're creating a web application.

If you are using an IDE, such as Eclipse, you have to remember to add the library to your build path before the IDE will recognize it and allow you to use the library.

just use following

height:auto;

With C++11 the iteration syntax is simple. You still iterate over pairs, but accessing just the key is easy.

#include <iostream>
#include <map>

int main()
{
    std::map<std::string, int> myMap;

    myMap["one"] = 1;
    myMap["two"] = 2;
    myMap["three"] = 3;

    for ( const auto &myPair : myMap ) {
        std::cout << myPair.first << "\n";
    }
}

The typeof operator isn't an infix (so the LHS of your example doesn't make sense).

You need to use it like so...

if (typeof a_string == 'string') {
    // This is a string.
}

Remember, typeof is an operator, not a function. Despite this, you will see typeof(var) being used a lot in the wild. This makes as much sense as var a = 4 + (1).

Also, you may as well use == (equality comparison operator) since both operands are Strings (typeof always returns a String), JavaScript is defined to perform the same steps had I used === (strict comparison operator).

As Box9 mentions, this won't detect a instantiated String object.

You can detect for that with....

var isString = str instanceof String;

jsFiddle.

...or...

var isString = str.constructor == String;

jsFiddle.

But this won't work in a multi window environment (think iframes).

You can get around this with...

var isString = Object.prototype.toString.call(str) == '[object String]';

jsFiddle.

But again, (as Box9 mentions), you are better off just using the literal String format, e.g. var str = 'I am a string';.

Based on Anastasiya's answer. I think this is the shortest vba command:

Option Explicit

Sub Sample()
    Dim sColumnLetter as String
    Dim iColumnNumber as Integer

    sColumnLetter = "C"
    iColumnNumber = Columns(sColumnLetter).Column

    MsgBox "The column number is " & iColumnNumber
End Sub

Caveat: The only condition for this code to work is that a worksheet is active, because Columns is equivalent to ActiveSheet.Columns. ;)

First of all you missed ScriptService attribute to add in webservice.

[ScriptService]

After then try following method to call webservice via JSON.

        var webAddr = "http://Domain/VBRService.asmx/callJson";
        var httpWebRequest = (HttpWebRequest)WebRequest.Create(webAddr);
        httpWebRequest.ContentType = "application/json; charset=utf-8";
        httpWebRequest.Method = "POST";            

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {
            string json = "{\"x\":\"true\"}";

            streamWriter.Write(json);
            streamWriter.Flush();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = streamReader.ReadToEnd();
            return result;

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

It can be due to a number of reasons happening when configuring the listener. Best way is to log and see the actual error. You can do this by adding a logging.properties file to the root of your classpath with the following contents:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

I was in a situation where I was looking for -s theirs but of course, this strategy doesn't exist. My history was that I had forked a project on GitHub, and now for some reason, my local master could not be merged with upstream/master although I had made no local changes to this branch. (Really don't know what happened there -- I guess upstream had done some dirty pushes behind the scenes, maybe?)

What I ended up doing was

# as per https://help.github.com/articles/syncing-a-fork/
git fetch upstream
git checkout master
git merge upstream/master
....
# Lots of conflicts, ended up just abandonging this approach
git reset --hard   # Ditch failed merge
git checkout upstream/master
# Now in detached state
git branch -d master # !
git checkout -b master   # create new master from upstream/master

So now my master is again in sync with upstream/master (and you could repeat the above for any other branch you also want to sync similarly).

I ran into an issue similar to what Martin Wilde described, in my case comparing the same directory on two different servers after mirroring with rsync.

Instead of using a script I added the -b flag to the du which counts the size in bytes and as far as I can determine eliminated the differences on the two servers. You still can use -s -h to get a comprehensible output.

It's not possible to specify expiration. It's completely up to the user.

https://developer.mozilla.org/en-US/docs/Web/API/Window/localStorage

Of course, it's possible that something your application stores on the client may not be there later. The user can explicitly get rid of local storage, or the browser may run into space considerations. It's good to program defensively. Generally however things remain "forever" based on some practical definition of that word.

edit — obviously, your own application can actively remove stuff if it decides it's too old. That is, you can explicitly include some sort of timestamp in what you've got saved, and then use that later to decide whether or not information should be flushed.

Just put a unicode newline character within the before pseudo element:

#restart:before { content: '\00000A'; }

decimal.js, big.js or bignumber.js can be used to avoid floating-point manipulation problems in Javascript:

You might want to look at docker volumes if you you want to persist the data in your container. Visit https://docs.docker.com/engine/tutorials/dockervolumes/. The docker documentation is a very good place to start

All of the rules concerning the encoding of URIs (which contains URNs and URLs) are specified in the RFC1738 and the RFC3986, here's a TL;DR of these long and boring documents:

Percent-encoding, also known as URL encoding, is a mechanism for encoding information in a URI under certain circumstances. The characters allowed in a URI are either reserved or unreserved. Reserved characters are those characters that sometimes have special meaning, but they are not the only characters that needs encoding.

There are 66 unreserved characters that doesn't need any encoding: abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_.~

There are 18 reserved characters which needs to be encoded: !*'();:@&=+$,/?#[], and all the other characters must be encoded.

To percent-encode a character, simply concatenate "%" and its ASCII value in hexadecimal. The php functions "urlencode" and "rawurlencode" do this job for you.

The difference between gcc and g++ are:

     gcc            |        g++
compiles c source   |   compiles c++ source

use g++ instead of gcc to compile you c++ source.

I know you already accepted the other answer, but if you want to do this as a DataFrame, just use groupBy and agg. Assuming you had a DF already created (with columns named "col1", "col2", etc) you could do:

myDF.groupBy($"col1", $"col3", $"col4").agg($"col1", max($"col2"), $"col3", $"col4")

Note that in this case, I chose the Max of col2, but you could do avg, min, etc.

You need to update the execution permission for gradlew

Locally: chmod +x gradlew

Git:

git update-index --chmod=+x gradlew
git add .
git commit -m "Changing permission of gradlew"
git push

You should see:

mode change 100644 => 100755 gradlew

I get the same exception for .xls file, but after I open the file and save it as xlsx file , the below code works:

 try(InputStream is =file.getInputStream()){
      XSSFWorkbook workbook = new XSSFWorkbook(is);
      ...
 }

Using the RESTORE DATABASE command most likely. bak is a common extension used for a database backup file. You'll find documentation for this command on MSDN.

May be I come later to answer but right now I'm facing with this... if helps there are one more solution (the way i solved it).

    var query2 = (
    from users in Repo.T_Benutzer
    join mappings in Repo.T_Benutzer_Benutzergruppen on mappings.BEBG_BE equals users.BE_ID into tmpMapp
    join groups in Repo.T_Benutzergruppen on groups.ID equals mappings.BEBG_BG into tmpGroups
    from mappings in tmpMapp.DefaultIfEmpty()
    from groups in tmpGroups.DefaultIfEmpty()
    select new
    {
         UserId = users.BE_ID
        ,UserName = users.BE_User
        ,UserGroupId = mappings.BEBG_BG
        ,GroupName = groups.Name
    }

);

By the way, I tried using the Stefan Steiger code which also helps but it was slower as hell.

The ngRoute module is no longer part of the core angular.js file. If you are continuing to use $routeProvider then you will now need to include angular-route.js in your HTML:

<script src="angular.js">
<script src="angular-route.js">

API Reference

You also have to add ngRoute as a dependency for your application:

var app = angular.module('MyApp', ['ngRoute', ...]);

If instead you are planning on using angular-ui-router or the like then just remove the $routeProvider dependency from your module .config() and substitute it with the relevant provider of choice (e.g. $stateProvider). You would then use the ui.router dependency:

var app = angular.module('MyApp', ['ui.router', ...]);

The below code illustrates how using a generator returns a result before completion, unlike the traditional non generator approach that returns a complete array after full iteration. With the generator below, the values are returned when ready, no need to wait for an array to be completely filled:

<?php 

function sleepiterate($length) {
    for ($i=0; $i < $length; $i++) {
        sleep(2);
        yield $i;
    }
}

foreach (sleepiterate(5) as $i) {
    echo $i, PHP_EOL;
}
