Since React eventually boils down to plain old JavaScript, you can really place it anywhere! For instance, you could place it on a componentDidMount() in a React class.

For you edit, you may want to try something like this:

class Component extends React.Component {
  constructor(props) {
    super(props);
    this.onAddBucket = this.onAddBucket.bind(this);
  }
  componentWillMount() {
    this.setState({
      buckets: {},
    })
  }
  componentDidMount() {
    this.onAddBucket();
  }
  onAddBucket() {
    let self = this;
    let getToken = localStorage.getItem('myToken');
    var apiBaseUrl = "...";
    let input = {
      "name" :  this.state.fields["bucket_name"]
    }
    axios.defaults.headers.common['Authorization'] = getToken;
    axios.post(apiBaseUrl+'...',input)
    .then(function (response) {
      if (response.data.status == 200) {
        this.setState({
          buckets: this.state.buckets.concat(response.data.buckets),
        });
      } else {
        alert(response.data.message);
      }
    })
    .catch(function (error) {
      console.log(error);
    });
  }
  render() {
    return (
      {this.state.bucket}
    );
  }
}

Kotlin Style way to do this more simple (example):

    isVisible = false

Complete example:

    if (some_data_array.details == null){
                holder.view.some_data_array.isVisible = false}

Jon Skeet's answer is pretty much the solution in a nutshell, however if you are like me, you might want an explanation. The Subversion manual calls this a

Cherry-Pick Merge

From the man pages.

2. This form is called a 'cherry-pick' merge: '-r N:M' refers to the difference in the history of the source branch between revisions N and M.

   A 'reverse range' can be used to undo changes. For example, when source and target refer to the same branch, a previously committed revision can be 'undone'. In a reverse range, N is greater than M in '-r N:M', or the '-c' option is used with a negative number: '-c -M' is equivalent to '-r M:'. Undoing changes like this is also known as performing a 'reverse merge'.

• If the source is a file, then differences are applied to that file (useful for reverse-merging earlier changes). Otherwise, if the source is a directory, then the target defaults to '.'.

  In normal usage the working copy should be up to date, at a single revision, with no local modifications and no switched subtrees.

Example:

svn merge -r 2983:289 path/to/file

This will replace the local copy[2983] (which, according to the quote above, should be in sync with the server--your responsibility) with the revision 289 from the server. The change happens locally, which means if you have a clean checkout, then the changes can be inspected before committing them.

For those very beginners who has spend few hours for this commit (with comment and no verify) with no further issue

git commit -m "Some comments" --no-verify

The proper way is to do a Time.now.getutc.to_i to get the proper timestamp amount as simply displaying the integer need not always be same as the utc timestamp due to time zone differences.

If you are wanting to just copy the whole column, you can simplify the code a lot by doing something like this:

Sub CopyCol()

    Sheets("Sheet1").Columns(1).Copy

    Sheets("Sheet2").Columns(2).PasteSpecial xlPasteValues

End Sub

Or

Sub CopyCol()

    Sheets("Sheet1").Columns("A").Copy

    Sheets("Sheet2").Columns("B").PasteSpecial xlPasteValues

End Sub

Or if you want to keep the loop

Public Sub CopyrangeA()

    Dim firstrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    firstrowDB = 1
    arr1 = Array("BJ", "BK")
    arr2 = Array("A", "B")

    For i = LBound(arr1) To UBound(arr1)

        Sheets("Sheet1").Columns(arr1(i)).Copy

        Sheets("Sheet2").Columns(arr2(i)).PasteSpecial xlPasteValues

    Next
    Application.CutCopyMode = False

End Sub

Try this cmd in terminal

$ ulimit -c unlimited

Do like this

List<Object[]> list = HQL.list(); // get your lsit here but in Object array

your query is : "SELECT houses.id, addresses.country, addresses.region,..."

for(Object[] obj : list){
String houseId = String.valueOf(obj[0]); // houseId is at first place in your query
String country = String.valueof(obj[1]); // country is at second and so on....
.......
}

this way you can get the mixed objects with ease, but you should know in advance at which place what value you are getting or you can just check by printing the values to know. sorry for the bad english I hope this help

Got same problem with project porting from VS2013 to VS2017,
Fix: change "Properties->General->Windows SDK Version" to 10

I think Amith Koujalgi is correct but also, in cases where the webservice responses are in JSON then it might be more useful to see the results in a clean JSON format instead of a very long string. Just add | grep }| python -mjson.tool to the end of curl commands here is two examples:

GET approach with JSON result

curl -i -H "Accept: application/json" http://someHostName/someEndpoint | grep }| python -mjson.tool 

POST approach with JSON result

curl -X POST  -H "Accept: Application/json" -H "Content-Type: application/json" http://someHostName/someEndpoint -d '{"id":"IDVALUE","name":"Mike"}' | grep }| python -mjson.tool

I would use javascript for this.

var txtFile = new XMLHttpRequest();
txtFile.open("GET", "http://my.remote.url/myremotefile.txt", true);
txtFile.onreadystatechange = function() {
  if (txtFile.readyState === 4 && txtFile.status == 200) {
     allText = txtFile.responseText;
  }
document.getElementById('your div id').innerHTML = allText;

This is just a code sample, would need tweaking for all browsers, etc.

it may be very old post, but I would like to share my experience. I had the same issue when I used Pycharm and I installed the package from Project Interpreter page in the Project Settings/Preferences... That fixed the issue, please check below link: https://www.jetbrains.com/help/pycharm/installing-uninstalling-and-upgrading-packages.html?_ga=2.41088674.1813230270.1594526819-1842497340.1594080707

If you don't have permissions to change your default DB you could manually select a different DB at the top of your queries...

USE [SomeOtherDb]
SELECT 'I am now using a different DB'

Will work as long as you have permission to the other DB

File fileName = new File(".....\\Fund.xlsx");

public static void createWorkbook(File fileName) throws IOException {
    try {
        FileOutputStream fos = new FileOutputStream(fileName);
        XSSFWorkbook  workbook = new XSSFWorkbook();            

        XSSFSheet sheet = workbook.createSheet("fund");  

        Row row = sheet.createRow(0);   
        Cell cell0 = row.createCell(0);
        cell0.setCellValue("Nav Value");

        Cell cell1 = row.createCell(1);

        cell1.setCellValue("Amount Change");       

        Cell cell2 = row.createCell(2);
        cell2.setCellValue("Percent Change");

        workbook.write(fos);
        fos.flush();
        fos.close();
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block

Try this:

declare @procName varchar(500)
declare cur cursor 

for SELECT 'DROP PROCEDURE [' + SCHEMA_NAME(p.schema_id) + '].[' + p.NAME + ']'
FROM sys.procedures p 
open cur
fetch next from cur into @procName
while @@fetch_status = 0
begin
    exec( @procName )
    fetch next from cur into @procName
end
close cur
deallocate cur

Have you tried calling TcpClient.Dispose() explicitly?

And are you sure that you have TcpClient.Close() and TcpClient.Dispose()-ed ALL connections?

Just drag APK file to android emulator it will install automatically.

There should be

$('.send_upload')

but not $('.upload')

I used

a2ensite default-ssl

and it worked like a charm.

If you want to force e.g. phpmyadmin to use SSL/https you will run into this problem if this link is missing.

Java 7 and 8. Increment DOES change the reference, so it references to another Integer object. Look:

@Test
public void incInteger()
{
    Integer i = 5;
    Integer iOrig = i;
    ++i; // Same as i = i + 1;
    Assert.assertEquals(6, i.intValue());
    Assert.assertNotEquals(iOrig, i);
}

Integer by itself is still immutable.

using System.Windows.Forms;
...
MessageBox.Show("Hello World!");

This is not possible with the magic find methods. Try using the query builder:

$result = $em->getRepository("Orders")->createQueryBuilder('o')
   ->where('o.OrderEmail = :email')
   ->andWhere('o.Product LIKE :product')
   ->setParameter('email', '[email protected]')
   ->setParameter('product', 'My Products%')
   ->getQuery()
   ->getResult();

Math.floor(n)

where n is a double. This'll actually return a double, it seems, so make sure that you typecast it after.

The following takes any valid datetime value and returns the number of days in the associated month... it eliminates the ambiguity of both other answers...

 // pass in any date as parameter anyDateInMonth
function daysInMonth(anyDateInMonth) {
    return new Date(anyDateInMonth.getFullYear(), 
                    anyDateInMonth.getMonth()+1, 
                    0).getDate();}

ExpressiveAnnotations gives you such a possibility:

[Required]
[AssertThat("Length(FieldA) + Length(FieldB) + Length(FieldC) + Length(FieldD) > 50")]
public string FieldA { get; set; }

Download Microsoft Drivers for PHP for SQL Server. Extract the files and use one of:

File                             Thread Safe         VC Bulid
php_sqlsrv_53_nts_vc6.dll           No                  VC6
php_sqlsrv_53_nts_vc9.dll           No                  VC9
php_sqlsrv_53_ts_vc6.dll            Yes                 VC6
php_sqlsrv_53_ts_vc9.dll            Yes                 VC9

You can see the Thread Safety status in phpinfo().

Add the correct file to your ext directory and the following line to your php.ini:

extension=php_sqlsrv_53_*_vc*.dll

Use the filename of the file you used.

As Gordon already posted this is the new Extension from Microsoft and uses the sqlsrv_* API instead of mssql_*

Update:
On Linux you do not have the requisite drivers and neither the SQLSERV Extension.
Look at Connect to MS SQL Server from PHP on Linux? for a discussion on this.

In short you need to install FreeTDS and YES you need to use mssql_* functions on linux. see update 2

To simplify things in the long run I would recommend creating a wrapper class with requisite functions which use the appropriate API (sqlsrv_* or mssql_*) based on which extension is loaded.

Update 2: You do not need to use mssql_* functions on linux. You can connect to an ms sql server using PDO + ODBC + FreeTDS. On windows, the best performing method to connect is via PDO + ODBC + SQL Native Client since the PDO + SQLSRV driver can be incredibly slow.

Response.Redirect is more costly since it adds an extra trip to the server to figure out where to go.

Server.Transfer is more efficient however it can be a little mis-leading to the user since the Url doesn't physically change.

In my experience, the difference in performance has not been significant enough to use the latter approach

I created a C++ open source project for normally distributed random number generation benchmark.

It compares several algorithms, including

• Central limit theorem method
• Box-Muller transform
• Marsaglia polar method
• Ziggurat algorithm
• Inverse transform sampling method.
• cpp11random uses C++11 std::normal_distribution with std::minstd_rand (it is actually Box-Muller transform in clang).

The results of single-precision (float) version on iMac [email protected] , clang 6.1, 64-bit:

For correctness, the program verifies the mean, standard deviation, skewness and kurtosis of the samples. It was found that CLT method by summing 4, 8 or 16 uniform numbers do not have good kurtosis as the other methods.

Ziggurat algorithm has better performance than the others. However, it does not suitable for SIMD parallelism as it needs table lookup and branches. Box-Muller with SSE2/AVX instruction set is much faster (x1.79, x2.99) than non-SIMD version of ziggurat algorithm.

Therefore, I will suggest using Box-Muller for architecture with SIMD instruction sets, and may be ziggurat otherwise.

P.S. the benchmark uses a simplest LCG PRNG for generating uniform distributed random numbers. So it may not be sufficient for some applications. But the performance comparison should be fair because all implementations uses the same PRNG, so the benchmark mainly tests the performance of the transformation.

Cross browser window.load event

function load(){}

window[ addEventListener ? 'addEventListener' : 'attachEvent' ]( addEventListener ? 'load' : 'onload', load )

If you want to add a sourceSet for testing in addition to all the existing ones, within a module regardless of the active flavor:

sourceSets {
    test {
        java.srcDirs += [
                'src/customDir/test/kotlin'
        ]
        print(java.srcDirs)   // Clean
    }
}

Pay attention to the operator += and if you want to run integration tests change test to androidTest.

I solved the problem by adding the following dependency

<dependency>
    <groupId>javax.persistence</groupId>
    <artifactId>persistence-api</artifactId>
    <version>2.2</version>
</dependency>

Together with

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jdbc</artifactId>
</dependency>

Because comparaison method have to be done based on type int (x==y) or class Integer (x.equals(y)) with right operator

public class Example {

    public static void main(String[] args) {
     int[] arr = {-32735, -32735, -32700, -32645, -32645, -32560, -32560};

        for(int j=1; j<arr.length-1; j++)
            if((arr[j-1]!=arr[j]) && (arr[j]!=arr[j+1])) 
                System.out.println("int>"+arr[j]);


    Integer[] I_arr = {-32735, -32735, -32700, -32645, -32645, -32560, -32560};

        for(int j=1; j<I_arr.length-1; j++)
            if((!I_arr[j-1].equals(I_arr[j])) && (!I_arr[j].equals(I_arr[j+1]))) 
                System.out.println("Interger>"+I_arr[j]);
    }
}

Here is a good summary:

A Stored Procedure:

• Accepts parameters
• Can NOT be used as building block in a larger query
• Can contain several statements, loops, IF ELSE, etc.
• Can perform modifications to one or several tables
• Can NOT be used as the target of an INSERT, UPDATE or DELETE statement.

A View:

• Does NOT accept parameters
• Can be used as building block in a larger query
• Can contain only one single SELECT query
• Can NOT perform modifications to any table
• But can (sometimes) be used as the target of an INSERT, UPDATE or DELETE statement.

use the arguments -Xms<memory> -Xmx<memory>. Use M or G after the numbers for indicating Megs and Gigs of bytes respectively. -Xms indicates the minimum and -Xmx the maximum.

keytool is part of the standard java distribution.

In a windows 64-bit machine, you would normally find the jdk at

C:\Program Files\Java\jdk1.8.0_121\bin

It is used for managing keys and certificates you can sign things with, in your case, probably a jar file.

If you provide more details of what you need to do, we could probably give you a more specific answer.

Yes. add a linked server entry, and use select into using the four part db object naming convention.

Example:

SELECT * INTO targetTable 
FROM [sourceserver].[sourcedatabase].[dbo].[sourceTable]

By specifying the option --user and --ask-password wget will ask for the credentials. Below is an example. Change the username and download link to your needs.

wget --user=username --ask-password https://xyz.com/changelog-6.40.txt

It's likely that the download was corrupted if you are getting an error with the disk image. Go back to the downloads page at https://developers.google.com/appengine/downloads and look at the SHA1 checksum. Then, go to your Terminal app on your mac and run the following:

openssl sha1 [put the full path to the file here without brackets] 

For example:

openssl sha1 /Users/me/Desktop/myFile.dmg 

If you get a different value than the one on the Downloads page, you know your file is not properly downloaded and you should try again.

This question pops up top in Google, so in my case, I used the css snippet from https://css-tricks.com/snippets/css/truncate-string-with-ellipsis/ but applying it to the td did NOT give the desired result.

I had to add a div tag around the text in the td and the ellipsis finally worked.

Abbreviated HTML Code;

<table style="width:100%">
 <tr>
    <td><div class='truncate'>Some Long Text Here</div></td>
 </tr>
</table>

Abbreviated CSS;

.truncate { width: 300px; white-space:nowrap; overflow:hidden; text-overflow:ellipsis; }

Seems like you might want a treemap.

You can pass in a custom comparator to it if that applies.

This might be completely off base, but can't you just copy the whole column into a new spreadsheet and then sort the column? I'm assuming that you don't need to maintain the order integrity.

Little comment to answer:

if you have several virtual hosts on several IPs in several config files in sites-available/, than "default" domain for IP will be taken from first file by alphabetic order.

And as Pavel said, there is "default_server" argument for "listen" directive http://nginx.org/en/docs/http/ngx_http_core_module.html#listen

I think i know what you mean, if you want to send an array through a URL you can use serialize

for example:

$foo = array(1,2,3);
$serialized_array = serialize($foo);
$url = "http://www.foo.whatever/page.php?vars=".urlencode($serialized_array);

and on page.php

$vars = unserialize($_GET['vars']);

There's a small problem with the formula that you found on Google. It should be:
(int)(Math.random() * (max - min + 1) + min)
not
(int)(Math.random() * (max - min) + min) .

max - min + 1 is the range in which random numbers can be generated

You can also use

./gradlew clean build (Mac and Linux) -With ./

gradlew clean build (Windows) -Without ./

it removes build folder, as well configure your modules and then build your project.

i use it before release any new app on playstore.

These are the prerequisites of directly using the script name:

1. Add the shebang line (#!/bin/bash) at the very top.
2. Use chmod u+x scriptname to make the script executable (where scriptname is the name of your script).
3. Place the script under /usr/local/bin folder.
   • Note: I suggest placing it under /usr/local/bin because most likely that path will be already added to your PATH variable.
4. Run the script using just its name, scriptname.

If you don't have access to /usr/local/bin then do the following:

1. Create a folder in your home directory and call it bin.

2. Do ls -lA on your home directory, to identify the start-up script your shell is using. It should be either .profile or .bashrc.

3. Once you have identified the start up script, add the following line:

   PATH="$PATH:$HOME/bin"
   

4. Once added, source your start-up script or log out and log back in.

   To source, put . followed by a space and then your start-up script name, e.g. . .profile or . .bashrc

5. Run the script using just its name, scriptname.

apt-get install python-setuptools python-pip

or

apt-get install python3-setuptools python3-pip

you'd also want to install the python packages...

or you can

SELECT
  String_to_array(CASE
    WHEN <condition 1> THEN a1||','||b1
    WHEN <condition 2> THEN a2||','||b2
    ELSE a3||','||b3
  END, ',') K
FROM <table>

Like this:

<?php

    if (isset($_SERVER["HTTP_REFERER"])) {
        header("Location: " . $_SERVER["HTTP_REFERER"]);
    }

?>

If you didn't commit it to the master branch yet, its easy:

• get off the master branch (like git checkout -b oops/fluke/dang)
• commit your changes there (like git add -u; git commit;)
• go back the master branch (like git checkout master)

Your changes will be saved in branch oops/fluke/dang; master will be as it was.

http://en.wikipedia.org/wiki/Division_by_zero

http://en.wikipedia.org/wiki/Unix_signal#SIGFPE

This should give you a really good idea. Since a modulus is, in its basic sense, division with a remainder, something % 0 IS division by zero and as such, will trigger a SIGFPE being thrown.

Column letter from column number can be extracted using formula by following steps
1. Calculate the column address using ADDRESS formula
2. Extract the column letter using MID and FIND function

Example:
1. ADDRESS(1000,1000,1)
results $ALL$1000
2. =MID(F15,2,FIND("$",F15,2)-2)
results ALL asuming F15 contains result of step 1

In one go we can write
MID(ADDRESS(1000,1000,1),2,FIND("$",ADDRESS(1000,1000,1),2)-2)

As I commented you need to use a StringIO object and decode i.e c=pd.read_csv(io.StringIO(s.decode("utf-8"))) if using requests, you need to decode as .content returns bytes if you used .text you would just need to pass s as is s = requests.get(url).text c = pd.read_csv(StringIO(s)).

A simpler approach is to pass the correct url of the raw data directly to read_csv, you don't have to pass a file like object, you can pass a url so you don't need requests at all:

c = pd.read_csv("https://raw.githubusercontent.com/cs109/2014_data/master/countries.csv")

print(c)

Output:

                              Country         Region
0                             Algeria         AFRICA
1                              Angola         AFRICA
2                               Benin         AFRICA
3                            Botswana         AFRICA
4                             Burkina         AFRICA
5                             Burundi         AFRICA

From the docs:

filepath_or_buffer :

string or file handle / StringIO The string could be a URL. Valid URL schemes include http, ftp, s3, and file. For file URLs, a host is expected. For instance, a local file could be file ://localhost/path/to/table.csv

foreach (GridViewRow gvr in gvMyGridView.Rows)
{
    string PrimaryKey = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
}

You can use this code while doing an iteration with foreach or for any GridView event like OnRowDataBound.

Here you can input multiple values for DataKeyNames by separating with comma ,. For example, DataKeyNames="ProductID,ItemID,OrderID".

You can now access each of DataKeys by providing its index like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values[0].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values[1].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values[2].ToString();

You can also use Key Name instead of its index to get the values from DataKeyNames collection like below:

string ProductID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ProductID"].ToString();
string ItemID = gvMyGridView.DataKeys[gvr.RowIndex].Values["ItemID"].ToString();
string OrderID = gvMyGridView.DataKeys[gvr.RowIndex].Values["OrderID"].ToString();

At last I found the answer:

Just add this line before the line where you get error in your php file

ini_set('memory_limit', '-1');

It will take unlimited memory usage of server, it's working fine.

Consider '44M' instead of '-1' for safe memory usage.

Additional Information.

This is a bit high-level answer for applications which want to seamlessly fit into the Windows environment. Technical details of playing particular sound were provided in other answers. Besides that, always note these two points:

1. Use five standard system sounds in typical scenarios, i.e.

   • Asterisk - play when you want to highlight current event

   • Question - play with questions (system message box window plays this one)

   • Exclamation - play with excalamation icon (system message box window plays this one)

   • Beep (default system sound)

   • Critical stop ("Hand") - play with error (system message box window plays this one)
      

   Methods of class System.Media.SystemSounds will play them for you.
    

2. Implement any other sounds as customizable by your users in Sound control panel

   • This way users can easily change or remove sounds from your application and you do not need to write any user interface for this – it is already there
   • Each user profile can override these sounds in own way
   • How-to:
     • Create sound profile of your application in the Windows Registry (Hint: no need of programming, just add the keys into installer of your application.)
     • In your application, read sound file path or DLL resource from your registry keys and play it. (How to play sounds you can see in other answers.)

Just took a look over the mustache docs and they support "inverted sections" in which they state

they (inverted sections) will be rendered if the key doesn't exist, is false, or is an empty list

http://mustache.github.io/mustache.5.html#Inverted-Sections

{{#value}}
  value is true
{{/value}}
{{^value}}
  value is false

This is my edited version : you just need to add an extra argument "autoClose".

example :

 $('input[name="fieldName"]').datepicker({ autoClose: true});

also you can specify a close callback if you want. :)

replace datepicker.js with this:

!function( $ ) {

In openCV whenever you try to display an oversized image or image bigger than your display resolution you get the cropped display. It's a default behaviour.
In order to view the image in the window of your choice openCV encourages to use named window. Please refer to namedWindow documentation

The function namedWindow creates a window that can be used as a placeholder for images and trackbars. Created windows are referred to by their names.

cv.namedWindow(name, flags=CV_WINDOW_AUTOSIZE) where each window is related to image container by the name arg, make sure to use same name

eg:

import cv2
frame = cv2.imread('1.jpg')
cv2.namedWindow("Display 1")
cv2.resizeWindow("Display 1", 300, 300)
cv2.imshow("Display 1", frame)

Yes, this is possible now in browsers also. Chrome release this feature in version 84 and above. With the help of WEBOTP API, we can detect OTP on the web for mobile devices.

Here is a Web-OTP integrated code with Angular PWA Apps: https://github.com/Rohit3230/webOtpAutoReadByAngular

Go for live working URL for angular PWA app. https://rohit3230.github.io/webOtpAutoReadByAngular/

Solved my issue in Ubuntu 14.04 OS with python 2.7.6, by adding below two lines into ~/.bash_profile (or ~/.bashrc in unix) files.

source "/usr/local/bin/virtualenvwrapper.sh"

export WORKON_HOME="/opt/virtual_env/"

And then executing both these lines onto the terminal.

You need to add position:relative to #wrap element.

When you add this, all child elements will be positioned in this element, not browser window.

All you need to do is a post request like below :-

POST https://www.googleapis.com/oauth2/v4/token
Content-Type: application/json

{
  "client_id": <client_id>,
  "client_secret": <client_secret>,
  "refresh_token": <refresh_token>,
  "grant_type": "refresh_token"
}

"How to: Pad a Number with Leading Zeros" http://msdn.microsoft.com/en-us/library/dd260048.aspx

"all" option does not work anymore, The new parameter is;

x = pd.merge(df1, df2, how="outer")

Use Enum's static method, GetNames. It returns a string[], like so:

Enum.GetNames(typeof(DataSourceTypes))

If you want to create a method that does only this for only one type of enum, and also converts that array to a List, you can write something like this:

public List<string> GetDataSourceTypes()
{
    return Enum.GetNames(typeof(DataSourceTypes)).ToList();
}

You will need Using System.Linq; at the top of your class to use .ToList()

$( "#sortable" ).sortable({
    change: function(event, ui) {       
        var pos = ui.helper.index() < ui.placeholder.index() 
            ? { start: ui.helper.index(), end: ui.placeholder.index() }
            : { start: ui.placeholder.index(), end: ui.helper.index() }

        $(this)
            .children().removeClass( 'highlight' )
            .not( ui.helper ).slice( pos.start, pos.end ).addClass( 'highlight' );
    },
    stop: function(event, ui) {
        $(this).children().removeClass( 'highlight' );
    }
});

FIDDLE

An example of how it could be done inside change event without storing arbitrary data into element storage. Since the element where drag starts is ui.helper, and the element of current position is ui.placeholder, we can take the elements between those two indexes and highlight them. Also, we can use this inside handler since it refers to the element that the widget is attached. The example works with dragging in both directions.

INSERT INTO <table> (<date_column>) VALUES ('1/1/2010 12:00')

Another situation when you may need this is if you have stl collection of pointers and want to change them using stl algorithm. Example of for_each in c++98.

struct Storage {
  typedef std::list<Object*> ObjectList;
  ObjectList objects;

  void change() {
    typedef void (*ChangeFunctionType)(Object*&);
    std::for_each<ObjectList::iterator, ChangeFunctionType>
                 (objects.begin(), objects.end(), &Storage::changeObject);
  }

  static void changeObject(Object*& item) {
    delete item;
    item = 0;
    if (someCondition) item = new Object();
  } 

};

Otherwise, if you use changeObject(Object* item) signature you have copy of pointer, not original one.

I had a similar error, but for me it seemed to be caused by re-using an IAM user to work with S3 in two different Elastic Beanstalk environments. I treated the symptom by creating an identically permissioned IAM user for each environment and that made the error go away.

Here is a very good tutorial on how to build a custom context menu with a full working code example (without JQuery and other libraries).

You can also find their demo code on GitHub.

They give a detailed step-by-step explanation that you can follow along to build your own right-click context menu (including html, css and javascript code) and summarize it at the end by giving the complete example code.

You can follow along easily and adapt it to your own needs. And there is no need for JQuery or other libraries.

This is how their example menu code looks like:

<nav id="context-menu" class="context-menu">
    <ul class="context-menu__items">
      <li class="context-menu__item">
        <a href="#" class="context-menu__link" data-action="View"><i class="fa fa-eye"></i> View Task</a>
      </li>
      <li class="context-menu__item">
        <a href="#" class="context-menu__link" data-action="Edit"><i class="fa fa-edit"></i> Edit Task</a>
      </li>
      <li class="context-menu__item">
        <a href="#" class="context-menu__link" data-action="Delete"><i class="fa fa-times"></i> Delete Task</a>
      </li>
    </ul>
  </nav>

A working example (task list) can be found on codepen.

I don't think you can in a self-contained service (when you call Restart, it will stop the service, which will interrupt the Restart command, and it won't ever get started again). If you can add a second .exe (a Console app that uses the ServiceManager class), then you can kick off the standalone .exe and have it restart the service and then exit.

On second thought, you could probably have the service register a Scheduled Task (using the command-line 'at' command, for example) to start the service and then have it stop itself; that would probably work.

I have done this using LINQ:

var oCSP = (from P in db.Products select new { P.ProductName });

string joinedString = string.Join(",", oCSP.Select(p => p.ProductName));

onDestroyed()

is wrong name for

onDestroy()  

Did you make a mistake only in this question or in your code too?

The phone number data annotation attribute is for the data type, which is not related to the data display format. It's just a misunderstanding. Phone number means you can accept numbers and symbols used for phone numbers for this locale, but is not checking the format, length, range, or else. For display string format use the javascript to have a more dynamic user interaction, or a plugin for MVC mask, or just use a display format string properly.

If you are new to MVC programming put this code at the very end of your view file (.cshtml) and see the magic:

<script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script>
<script type="text/javascript">
    $(document).ready(function () {
        $("#the_id_of_your_field_control").keyup(function () {
            $(this).val($(this).val().replace(/^(\d{2})(\d{5})(\d{4})+$/, "($1) $2-$3"));
        });
    });
</script>

This format is currently used for mobile phones in Brazil. Adapt for your standard.

This will add the parenthesis and spaces to your field, which will increase the string length of your input data. If you want to save just the numbers you will have to trim out the non-numbers from the string before saving.

This could be complicated way of doing

String newString = new String(oldString);

This shortens the String is the underlying char[] used is much longer.

However more specifically it will be checking that every character can be UTF-8 encoded.

There are some "characters" you can have in a String which cannot be encoded and these would be turned into ?

Any character between \uD800 and \uDFFF cannot be encoded and will be turned into '?'

String oldString = "\uD800";
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8");
System.out.println(newString.equals(oldString));

prints

false

MAVEN_HOME is used for maven 1 and M2_HOME is used to locate maven 2. Having the two different _HOME variables means it is possible to run both on the same machine. And if you check old mvn.cmd scripts they have something like,

@REM ----------------------------------------------------------------------------
@REM Maven2 Start Up Batch script
@REM
@REM Required ENV vars:
@REM JAVA_HOME - location of a JDK home dir
@REM
@REM Optional ENV vars
@REM M2_HOME - location of maven2's installed home dir
@REM MAVEN_BATCH_ECHO - set to 'on' to enable the echoing of the batch commands
@REM MAVEN_BATCH_PAUSE - set to 'on' to wait for a key stroke before ending
@REM MAVEN_OPTS - parameters passed to the Java VM when running Maven
@REM     e.g. to debug Maven itself, use
@REM set MAVEN_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000
@REM MAVEN_SKIP_RC - flag to disable loading of mavenrc files
@REM ----------------------------------------------------------------------------

See that @REM M2_HOME - location of maven2's installed home dir

Anyway usage of this pattern is now deprecated with maven 3.5 as per the documentation.

Based on problems in using M2_HOME related to different Maven versions installed and to simplify things, the usage of M2_HOME has been removed and is not supported any more MNG-5823, MNG-5836, MNG-5607

So now the mvn.cmd look like,

@REM -----------------------------------------------------------------------------
@REM Apache Maven Startup Script
@REM
@REM Environment Variable Prerequisites
@REM
@REM   JAVA_HOME          Must point at your Java Development Kit installation.
@REM   MAVEN_BATCH_ECHO  (Optional) Set to 'on' to enable the echoing of the batch commands.
@REM   MAVEN_BATCH_PAUSE (Optional) set to 'on' to wait for a key stroke before ending.
@REM   MAVEN_OPTS        (Optional) Java runtime options used when Maven is executed.
@REM   MAVEN_SKIP_RC     (Optional) Flag to disable loading of mavenrc files.
@REM -----------------------------------------------------------------------------

So what you need is JAVA_HOME to be set correctly. As per the new installation guide (as of 12/29/2017), Just add the maven bin directory path to the PATH variable. It should do the trick.

ex : export PATH=/opt/apache-maven-3.5.2/bin:$PATH

If your code seems too unwieldy, a function might help:

def clamp(minvalue, value, maxvalue):
    return max(minvalue, min(value, maxvalue))

new_index = clamp(0, new_index, len(mylist)-1)

If you set android:singleLine="true", automatically the button hides the keyboard¡

To open the Eye Dropper simply:

1. Open DevTools F12
2. Go to Elements tab
3. Under Styles side bar click on any color preview box

Its main functionality is to inspect pixel color values by clicking them though with its new features you can also see your page's existing colors palette or material design palette by clicking on the two arrows icon at the bottom. It can get quite handy when designing your page.

In IIS, you can specify a redirect to "certain" page based on error code. In you example, you can configure 404 - > Your customized 404 error page.

dict.iteritems() in python 2 is equivalent to dict.items() in python 3.

If the OpenSSL headers are in the openssl sub-directory of the current directory, use:

gcc -I. -o Opentest Opentest.c -lcrypto

The pre-processor looks to create a name such as "./openssl/ssl.h" from the "." in the -I option and the name specified in angle brackets. If you had specified the names in double quotes (#include "openssl/ssl.h"), you might never have needed to ask the question; the compiler on Unix usually searches for headers enclosed in double quotes in the current directory automatically, but it does not do so for headers enclosed in angle brackets (#include <openssl/ssl.h>). It is implementation defined behaviour.

You don't say where the OpenSSL libraries are - you might need to add an appropriate option and argument to specify that, such as '-L /opt/openssl/lib'.

Nothing works from this tread. "forRoot" doesn't help.

Sorry. Sorted this out. I've managed to make it work by setting correct "routes" for this "forRoot" router setup routine

    import {RouterModule, Routes} from '@angular/router';    
    import {AppComponent} from './app.component';
    
    const appRoutes: Routes = [
      {path: 'UI/part1/Details', component: DetailsComponent}
    ];
    
    @NgModule({
      declarations: [
        AppComponent,
        DetailsComponent
      ],
      imports: [
        BrowserModule,
        HttpClientModule,
        RouterModule.forRoot(appRoutes)
      ],
      providers: [DetailsService],
      bootstrap: [AppComponent]
    })

Also may be helpful (spent some time to realize this) Optional route part:

    const appRoutes: Routes = [
       {path: 'UI/part1/Details', component: DetailsComponent},
       {path: ':project/UI/part1/Details', component: DetailsComponent}
    ];

Second rule allows to open URLs like
hostname/test/UI/part1/Details?id=666
and
hostname/UI/part1/Details?id=666

Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2 (I have 3 years experience with enterprise level ExtJS)

As of this writing, it was necessary to:

1. Select 'Manage all projects' from the dropdown list at the top of the Console page
2. Click the delete button (trashcan icon) for the specific project on the project listing page

You don't use ls to get a file's permission information. You use the stat command. It will give you the numerical values you want. The "Unix Way" says that you should invent your own script using ls (or 'echo *') and stat and whatever else you like to give the information in the format you desire.

This is the most comprehensive solution I've tried so far:

const STANDARD_HTML_ENTITIES = {
    nbsp: String.fromCharCode(160),
    amp: "&",
    quot: '"',
    lt: "<",
    gt: ">"
};

const replaceHtmlEntities = plainTextString => {
    return plainTextString
        .replace(/&#(\d+);/g, (match, dec) => String.fromCharCode(dec))
        .replace(
            /&(nbsp|amp|quot|lt|gt);/g,
            (a, b) => STANDARD_HTML_ENTITIES[b]
        );
};

System.IO.Path.GetTempPath()

The path specified by the TMP environment variable. The path specified by the TEMP environment variable. The path specified by the USERPROFILE environment variable. The Windows directory.

If polling is good enough for you, I'd just watch if the "modified time" file stat changes. To read it:

os.stat(filename).st_mtime

(Also note that the Windows native change event solution does not work in all circumstances, e.g. on network drives.)

import os

class Monkey(object):
    def __init__(self):
        self._cached_stamp = 0
        self.filename = '/path/to/file'

    def ook(self):
        stamp = os.stat(self.filename).st_mtime
        if stamp != self._cached_stamp:
            self._cached_stamp = stamp
            # File has changed, so do something...

mx.iloc[0].idxmax()

This one line of code will give you how to find the maximum value from a row in dataframe, here mx is the dataframe and iloc[0] indicates the 0th index.

A simple example in Groovy for your reference:

def outer() {
    def x = 1
    return { -> println(x)} // inner
}
def innerObj = outer()
innerObj() // prints 1

If you want to remove characters that satisfy a specific condition, you may use this:

string s = "SoMEthInG";
s = new string(s.Where(c => char.IsUpper(c)).ToArray());

(This will leave only the uppercase characters in the string.)

In other words, you may "use" the string as an IEnumerable<char>, make changes on it and then convert it back to a string as shown above.

Again, this enables to not only remove a specific char because of the lambda expression, although you can do so if you change the lambda expression like this: c => c != 't'.

In package specs you can do all you mentioned but not sure about INDEX BY BINARY_INTEGER;

In package body:

initialize the table in declarations:

exch_rt exch_tbl := exch_tbl();

in order to add record to the local collection, in begin - end block you can do:

exch_rt.extend;
                                one_row.exch_rt_usd := 2;
                                one_row.exch_rt_eur := 1;
                                one_row.currency_cd := 'dollar';
                                exch_rt(1) := one_row; -- 1 - number of row in the table - you can put a variable which will be incremented inside a loop 

in order to get data from this table , inside package body you can use:

select exch_rt_usd, exch_rt_eur, currency_cd from table(exch_rt)

enjoy!

P.S. sorry for a late answer :D

It turned out I forgot to write my @implementation part.

In response to Thomas Browne's comment, because lnmx's answer only works for subtracting a date, here is a modification of his code that works for subtracting time from a time.Time type.

package main

import (
    "fmt"
    "time"
)

func main() {
    now := time.Now()

    fmt.Println("now:", now)

    count := 10
    then := now.Add(time.Duration(-count) * time.Minute)
    // if we had fix number of units to subtract, we can use following line instead fo above 2 lines. It does type convertion automatically.
    // then := now.Add(-10 * time.Minute)
    fmt.Println("10 minutes ago:", then)
}

Produces:

Not to mention, you can also use time.Hour or time.Second instead of time.Minute as per your needs.

When someone asks for "the number of processors/cores" there are 2 answers being requested. The number of "processors" would be the physical number installed in sockets on the machine.

The number of "cores" would be physical cores. Hyperthreaded (virtual) cores would not be included (at least to my mind). As someone who writes a lot of programs with thread pools, you really need to know the count of physical cores vs cores/hyperthreads. That said, you can modify the following script to get the answers that you need.

#!/bin/bash

MODEL=`cat /cpu/procinfo | grep "model name" | sort | uniq`
ALL=`cat /proc/cpuinfo | grep "bogo" | wc -l`
PHYSICAL=`cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l`
CORES=`cat /proc/cpuinfo | grep "cpu cores" | sort | uniq | cut -d':' -f2`
PHY_CORES=$(($PHYSICAL * $CORES))
echo "Type $MODEL"
echo "Processors $PHYSICAL"
echo "Physical cores $PHY_CORES"
echo "Including hyperthreading cores $ALL"

The result on a machine with 2 model Xeon X5650 physical processors each with 6 physical cores that also support hyperthreading:

Type model name : Intel(R) Xeon(R) CPU           X5650  @ 2.67GHz
Processors 2
Physical cores 12
Including hyperthreading cores 24

On a machine with 2 mdeol Xeon E5472 processors each with 4 physical cores that doesn't support hyperthreading

Type model name : Intel(R) Xeon(R) CPU           E5472  @ 3.00GHz
Processors 2
Physical cores 8
Including hyperthreading cores 8

When you use strace (on Linux) to run your binary, it will output the returns from system calls and what the error number means. This may sometimes be useful to you.

You would want to use CSS to achieve that.

say you have a table with the attribute id="my_table"

You would want to write the following in your css file

#my_table{
    margin-top:10px //moves your table 10pixels down
    margin-left:10px //moves your table 10pixels right
}

if you do not have a CSS file then you may just add margin-top:10px, margin-left:10px to the style attribute in your table element like so

<table style="margin-top:10px; margin-left:10px;">
    ....
</table>

There are a lot of resources on the net describing CSS and HTML in detail

For anyone else trying to do this in Sourcetree, there is no direct command in the UI for it (as of version 1.6.21.0). However, you can use the commands specified in the accepted answer by opening Terminal window (button available in the main toolbar) and copy/pasting them therein.

Note: Sourcetree's Search view can partially do text searching for you. Press Ctrl + 3 to go to Search view (or click Search tab available at the bottom). From far right, set Search type to File Changes and then type the string you want to search. This method has the following limitations compared to the above command:

1. Sourcetree only shows the commits that contain the search word in one of the changed files. Finding the exact file that contains the search text is again a manual task.
2. RegEx is not supported.

The bash script runs in a separate subshell. In order to make this work you will need to source this other script as well.

Think of it as enforcing Eager-Loading in a scenario where you sub-items would otherwise be lazy-loading.

The Query EF is sending to the database will yield a larger result at first, but on access no follow-up queries will be made when accessing the included items.

On the other hand, without it, EF would execute separte queries later, when you first access the sub-items.

Turns out, when the table name is different than the model name, you have to change the annotations to:

@Entity
@Table(name = "table_name")
class WhateverNameYouWant {
    ...

Instead of simply using the @Entity annotation.

What was weird for me, is that the class it was trying to convert to didn't exist. This worked for me.

You can use the .indexOf() and .substring(), like this:

var url = "www.aaa.com/task1/1.3.html#a_1";
var hash = url.substring(url.indexOf("#")+1);

You can give it a try here, if it may not have a # in it, do an if(url.indexOf("#") != -1) check like this:

var url = "www.aaa.com/task1/1.3.html#a_1", idx = url.indexOf("#");
var hash = idx != -1 ? url.substring(idx+1) : "";

If this is the current page URL, you can just use window.location.hash to get it, and replace the # if you wish.

A histogram is a poor-man's density estimate. Note that in your call to hist() using default arguments, you get frequencies not probabilities -- add ,prob=TRUE to the call if you want probabilities.

As for the log axis problem, don't use 'x' if you do not want the x-axis transformed:

plot(mydata_hist$count, log="y", type='h', lwd=10, lend=2)

gets you bars on a log-y scale -- the look-and-feel is still a little different but can probably be tweaked.

Lastly, you can also do hist(log(x), ...) to get a histogram of the log of your data.

There are two ways to connect remote redis server using redis-cli:

1. Using host & port individually as options in command

redis-cli -h host -p port

If your instance is password protected

redis-cli -h host -p port -a password

e.g. if my-web.cache.amazonaws.com is the host url and 6379 is the port

Then this will be the command:

redis-cli -h my-web.cache.amazonaws.com -p 6379

if 92.101.91.8 is the host IP address and 6379 is the port:

redis-cli -h 92.101.91.8 -p 6379

command if the instance is protected with password pass123:

redis-cli -h my-web.cache.amazonaws.com -p 6379 -a pass123

2. Using single uri option in command

redis-cli -u redis://password@host:port

command in a single uri form with username & password

redis-cli -u redis://username:password@host:port

e.g. for the same above host - port configuration command would be

redis-cli -u redis://[email protected]:6379

command if username is also provided user123

redis-cli -u redis://user123:[email protected]:6379

This detailed answer was for those who wants to check all options. For more information check documentation: Redis command line usage

First, double check that the branch has been actually pushed remotely, by using the command git ls-remote origin. If the new branch appears in the output, try and give the command git fetch: it should download the branch references from the remote repository.

If your remote branch still does not appear, double check (in the ls-remote output) what is the branch name on the remote and, specifically, if it begins with refs/heads/. This is because, by default, the value of remote.<name>.fetch is:

+refs/heads/*:refs/remotes/origin/*

so that only the remote references whose name starts with refs/heads/ will be mapped locally as remote-tracking references under refs/remotes/origin/ (i.e., they will become remote-tracking branches)

If you have created CMS block named 'block_identifier' from admin panel. Then following will be code to call them in .phtml

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml(); 
?> 

Yes, but not with that version of the constructor. You can do this:

>>> dict([(1, 2), (3, 4)])
{1: 2, 3: 4}

There are several different ways to make a dict. As documented, "providing keyword arguments [...] only works for keys that are valid Python identifiers."

Here is syntax for showing hours and minutes for a field coming out of a SELECT statement. In this example, the SQL field is named "UpdatedOnAt" and is a DateTime. Tested with MS SQL 2014.

SELECT Format(UpdatedOnAt ,'hh:mm') as UpdatedOnAt from MyTable

I like the format that shows the day of the week as a 3-letter abbreviation, and includes the seconds:

SELECT Format(UpdatedOnAt ,'ddd hh:mm:ss') as UpdatedOnAt from MyTable

The "as UpdatedOnAt" suffix is optional. It gives you a column heading equal tot he field you were selecting to begin with.

Find last time of update on a table

SELECT
tbl.name
,ius.last_user_update
,ius.user_updates
,ius.last_user_seek
,ius.last_user_scan
,ius.last_user_lookup
,ius.user_seeks
,ius.user_scans
,ius.user_lookups
FROM
sys.dm_db_index_usage_stats ius INNER JOIN
sys.tables tbl ON (tbl.OBJECT_ID = ius.OBJECT_ID)
WHERE ius.database_id = DB_ID()

we do check the IsDisposed property on the schedule component before using it in the Timer Tick event but it doesn't help.

If I understand that stack trace, it's not your timer which is the problem, it's one in the control itself - it might be them who are not cleaning-up properly.

Are you explicitly calling Dispose on their control?

Perl can be used for this, even on exotic platforms like AIX. Example:

#!/usr/bin/perl -w

use strict;
use Time::HiRes qw(gettimeofday);

my ($t_sec, $usec) = gettimeofday ();
my $msec= int ($usec/1000);

my ($sec,$min,$hour,$mday,$mon,$year,$wday,$yday,$isdst) =
    localtime ($t_sec);

printf "%04d-%02d-%02d %02d:%02d:%02d %03d\n",
    1900+$year, 1+$mon, $mday, $hour, $min, $sec, $msec;

This is because your data sending column type is integer and your are sending a string value to it.

So, the following way worked for me. Try with this one.

$insertQuery = "INSERT INTO workorders VALUES (
                    null,
                    '$priority',
                    '$requestType',
                    '$purchaseOrder',
                    '$nte',
                    '$jobSiteNumber'
                )";

Don't use 'null'. use it as null without single quotes.

Use Calendar.add(int field,int amount) method.

@Chaibi Alaa, To make the user able to add only once, and move the marker; You can set the marker on first click and then just change the position on subsequent clicks.

var marker;

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});


function placeMarker(location) {

    if (marker == null)
    {
          marker = new google.maps.Marker({
             position: location,
             map: map
          }); 
    } 
    else 
    {
        marker.setPosition(location); 
    } 
}

Replace

dateTime.setText(app.getTotalDl());

With

dateTime.setText(""+app.getTotalDl());

Please try this.

       <Router>
          <div>
            <Route exact path="/" component={Home} />
            <Route path="/news" component={NewsFeed} />
          </div>
        </Router> 

            

Here's how to do this with java.nio operations:

public static void copyFile(File sourceFile, File destFile) throws IOException {
    if(!destFile.exists()) {
        destFile.createNewFile();
    }

    FileChannel source = null;
    FileChannel destination = null;
    try {
        source = new FileInputStream(sourceFile).getChannel();
        destination = new FileOutputStream(destFile).getChannel();

        // previous code: destination.transferFrom(source, 0, source.size());
        // to avoid infinite loops, should be:
        long count = 0;
        long size = source.size();              
        while((count += destination.transferFrom(source, count, size-count))<size);
    }
    finally {
        if(source != null) {
            source.close();
        }
        if(destination != null) {
            destination.close();
        }
    }
}

In my practice i use Sequence Diagram Editor. it is really fast and helpful tool. the one thing i don't like about it is that it is commercial product, not free.

Looks like you've not encapsulated your string properly. Try this:

INSERT INTO custorder VALUES ('Kevin','yes'), STR_TO_DATE('1-01-2012', '%d-%m-%Y');

Alternatively, you can do the following but it is not recommended. Make sure that you use STR_TO-DATE it is because when you are developing web applications you have to explicitly convert String to Date which is annoying. Use first One.

INSERT INTO custorder VALUES ('Kevin','yes'), '2012-01-01';

I'm not confident that the above SQL is valid, however, and you may want to move the date part into the brackets. If you can provide the exact error you're getting, I might be able to more directly help with the issue.

I was scratching my head about this for a while too, and since Dave's explanation is a little hard to understand I'll post my (apparently working) code:

private class TabListener<T extends Fragment> implements ActionBar.TabListener {
    private Fragment mFragment;
    private Activity mActivity;
    private final String mTag;
    private final Class<T> mClass;

    public TabListener(Activity activity, String tag, Class<T> clz) {
        mActivity = activity;
        mTag = tag;
        mClass = clz;
        mFragment=mActivity.getFragmentManager().findFragmentByTag(mTag);
    }

    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        if (mFragment == null) {
            mFragment = Fragment.instantiate(mActivity, mClass.getName());
            ft.replace(android.R.id.content, mFragment, mTag);
        } else {
            if (mFragment.isDetached()) {
                ft.attach(mFragment);
            }
        }
    }

    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        if (mFragment != null) {
            ft.detach(mFragment);
        }
    }

    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }
}

As you can see it's pretty much like the Android sample, apart from not detaching in the constructor, and using replace instead of add.

After much headscratching and trial-and-error I found that finding the fragment in the constructor seems to make the double onCreateView problem magically go away (I assume it just ends up being null for onTabSelected when called through the ActionBar.setSelectedNavigationItem() path when saving/restoring state).

It seems that your configuration is using the print option for numpy.seterr:

>>> import numpy as np
>>> np.array([1])/0   #'warn' mode
__main__:1: RuntimeWarning: divide by zero encountered in divide
array([0])
>>> np.seterr(all='print')
{'over': 'warn', 'divide': 'warn', 'invalid': 'warn', 'under': 'ignore'}
>>> np.array([1])/0   #'print' mode
Warning: divide by zero encountered in divide
array([0])

This means that the warning you see is not a real warning, but it's just some characters printed to stdout(see the documentation for seterr). If you want to catch it you can:

1. Use numpy.seterr(all='raise') which will directly raise the exception. This however changes the behaviour of all the operations, so it's a pretty big change in behaviour.
2. Use numpy.seterr(all='warn'), which will transform the printed warning in a real warning and you'll be able to use the above solution to localize this change in behaviour.

Once you actually have a warning, you can use the warnings module to control how the warnings should be treated:

>>> import warnings
>>> 
>>> warnings.filterwarnings('error')
>>> 
>>> try:
...     warnings.warn(Warning())
... except Warning:
...     print 'Warning was raised as an exception!'
... 
Warning was raised as an exception!

Read carefully the documentation for filterwarnings since it allows you to filter only the warning you want and has other options. I'd also consider looking at catch_warnings which is a context manager which automatically resets the original filterwarnings function:

>>> import warnings
>>> with warnings.catch_warnings():
...     warnings.filterwarnings('error')
...     try:
...         warnings.warn(Warning())
...     except Warning: print 'Raised!'
... 
Raised!
>>> try:
...     warnings.warn(Warning())
... except Warning: print 'Not raised!'
... 
__main__:2: Warning: 

You can import database afterwards:

docker exec -i mysql-container mysql -uuser -ppassword name_db < data.sql

Simplest way - just put in the Eclipse plugins folder. You can start Eclipse with the -clean option to make sure Eclipse cleans its' plugins cache and sees the new plugin.

In general, it is far more recommended to install plugins using proper update sites.

Here is the latest method using the .map function in javascript.

Simple table code..

<table class="table table-hover">
    <thead class="thead-dark">
        <tr>
         <th scope="col">Tour</th>
         <th scope="col">Day</th>
         <th scope="col">Time</th>
         <th scope="col">Highlights</th>
         <th scope="col">Action</th>
       </tr>
    </thead>
  <tbody id="tableBody">
                            
  </tbody>

and here is javascript code to append something in the table body.

    const data = "some kind of json data or object of arrays";
                const tableData = data.map(function(value){
                    return (
                        `<tr>
                            <td>${value.Name}</td>
                            <td>${value.Day}</td>
                            <td>${value.Time}</td>
                            <td>${value.Highlights}</td>
                            <td class="text-center"><a class="btn btn-primary" href="route.html?id=${value.ID}" role="button">Details</a></td>
                        </tr>`
                    );
                }).join('');
            const tabelBody = document.querySelector("#tableBody");
                tableBody.innerHTML = tableData;

This solution also helps in cases of more than one extension like "Avishay.student.DB"

                FileInfo FileInf = new FileInfo(filePath);
                string strExtention = FileInf.Name.Replace(System.IO.Path.GetFileNameWithoutExtension(FileInf.Name), "");

You could always use a truncate method by setting a max-width and overflow ellipsis like this

p {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  max-width: 200px;
}

An example:

.wrapper {
  padding: 20px;
  background: #eaeaea;
  max-width: 400px;
  margin: 50px auto;
}

.demo-1 {
  overflow: hidden;
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
}

.demo-2 {
  overflow: hidden;
  white-space: nowrap;
  text-overflow: ellipsis;
  max-width: 150px;
}

<div class="wrapper">
  <p class="demo-1">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p>
</div>

<div class="wrapper">
  <p class="demo-2">Lorem ipsum dolor sit amet, consectetur adipisicing elit. Ut odio temporibus voluptas error distinctio hic quae corrupti vero doloribus optio! Inventore ex quaerat modi blanditiis soluta maiores illum, ab velit.</p>
</div>

For a multi-line truncation have a look at a flex solution. An example with truncation on 3 rows.

p {
  overflow: hidden;
  display: -webkit-box;
  -webkit-line-clamp: 3;
  -webkit-box-orient: vertical;
}

An example:

p {
  white-space: nowrap;
  overflow: hidden;
  text-overflow: ellipsis;
  max-width: 200px;
}

<p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Deserunt rem odit quis quaerat. In dolorem praesentium velit ea esse consequuntur cum fugit sequi voluptas ut possimus voluptatibus deserunt nisi eveniet!</p>

More readable way:

class A {
  void foo() throws MyException() {
    ...
  }
}

Just hide it in a RuntimeException to get it past forEach()

  void bar() throws MyException {
      Stream<A> as = ...
      try {
          as.forEach(a -> {
              try {
                  a.foo();
              } catch(MyException e) {
                  throw new RuntimeException(e);
              }
          });
      } catch(RuntimeException e) {
          throw (MyException) e.getCause();
      }
  }

Although at this point I won't hold against someone if they say skip the streams and go with a for loop, unless:

• you're not creating your stream using Collection.stream(), i.e. not straight forward translation to a for loop.
• you're trying to use parallelstream()

The error message is actually correct if not obvious. It says that your DOCTYPE must have a SYSTEM identifier. I assume yours only has a public identifier.

You'll get the error with (for instance):

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

You won't with:

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">

Notice "" at the end in the second one -- that's the system identifier. The error message is confusing: it should say that you need a system identifier, not that you need a space between the publicId and the (non-existent) systemId.

By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.

Best way to pass data from child to parent component

child component

handleLanguageCode=()=>(langValue) {
  this.props.sendDatatoParent(langValue)
}

Parent

<Parent sendDatatoParent={ data => this.setState({item: data}) } />;

I had a similar problem. npm install --only=dev didn't work, and neither did npm rebuild. Ultimately, I had to delete node_modules and package-lock.json and run npm install again. That fixed it for me.

One way is to use DBMS_ASSERT.SQL_OBJECT_NAME :

This function verifies that the input parameter string is a qualified SQL identifier of an existing SQL object.

DECLARE
    V_OBJECT_NAME VARCHAR2(30);
BEGIN
   BEGIN
        V_OBJECT_NAME  := DBMS_ASSERT.SQL_OBJECT_NAME('tab1');
        EXECUTE IMMEDIATE 'DROP TABLE tab1';

        EXCEPTION WHEN OTHERS THEN NULL;
   END;
END;

You should define the __unicode__ method on your model, and the template will call it automatically when you reference the instance.

Use the 'And' keyword for a logical and. Like this:

If Not ((filename = testFileName) And (fileName <> "")) Then

There are various libraries that can resolve E for you using techniques similar to what the Robertson article discussed. Here's an implemenation of createContents that uses TypeTools to resolve the raw class represented by E:

E createContents() throws Exception {
  return TypeTools.resolveRawArgument(SomeContainer.class, getClass()).newInstance();
}

This assumes that getClass() resolves to a subclass of SomeContainer and will fail otherwise since the actual parameterized value of E will have been erased at runtime if it's not captured in a subclass.

For Python 2:

>>> execfile('filename.py')

For Python 3:

>>> exec(open("filename.py").read())
# or
>>> from pathlib import Path
>>> exec(Path("filename.py").read_text())

See the documentation. If you are using Python 3.0, see this question.

See answer by @S.Lott for an example of how you access globals from filename.py after executing it.

This post has already a very good answer by "Community wiki" and I also recommend to look at Rick Strahl's Web Blog, there are many good posts about WCF Rest like this.

I used both to get this kind of MyService-service... Then I can use the REST-interface from jQuery or SOAP from Java.

This is from my Web.Config:

<system.serviceModel>
 <services>
  <service name="MyService" behaviorConfiguration="MyServiceBehavior">
   <endpoint name="rest" address="" binding="webHttpBinding" contract="MyService" behaviorConfiguration="restBehavior"/>
   <endpoint name="mex" address="mex" binding="mexHttpBinding" contract="MyService"/>
   <endpoint name="soap" address="soap" binding="basicHttpBinding" contract="MyService"/>
  </service>
 </services>
 <behaviors>
  <serviceBehaviors>
   <behavior name="MyServiceBehavior">
    <serviceMetadata httpGetEnabled="true"/>
    <serviceDebug includeExceptionDetailInFaults="true" />
   </behavior>
  </serviceBehaviors>
  <endpointBehaviors>
   <behavior name="restBehavior">
    <webHttp/>
   </behavior>
  </endpointBehaviors>
 </behaviors>
</system.serviceModel>

And this is my service-class (.svc-codebehind, no interfaces required):

    /// <summary> MyService documentation here ;) </summary>
[ServiceContract(Name = "MyService", Namespace = "http://myservice/", SessionMode = SessionMode.NotAllowed)]
//[ServiceKnownType(typeof (IList<MyDataContractTypes>))]
[ServiceBehavior(Name = "MyService", Namespace = "http://myservice/")]
public class MyService
{
    [OperationContract(Name = "MyResource1")]
    [WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "MyXmlResource/{key}")]
    public string MyResource1(string key)
    {
        return "Test: " + key;
    }

    [OperationContract(Name = "MyResource2")]
    [WebGet(ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource/{key}")]
    public string MyResource2(string key)
    {
        return "Test: " + key;
    }
}

Actually I use only Json or Xml but those both are here for a demo purpose. Those are GET-requests to get data. To insert data I would use method with attributes:

[OperationContract(Name = "MyResourceSave")]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "MyJsonResource")]
public string MyResourceSave(string thing){
    //...

Assume that you've defined do_something as a function, and you'd like to perform it N times. Maybe you can try the following:

todos = [do_something] * N  
for doit in todos:  
    doit()

From the MSDN page:

OPENQUERY does not accept variables for its arguments

Fundamentally, this means you cannot issue a dynamic query. To achieve what your sample is attempting, try this:

SELECT * FROM 
   OPENQUERY([NameOfLinkedSERVER], 'SELECT * FROM TABLENAME') T1 
   INNER JOIN 
   MYSQLSERVER.DATABASE.DBO.TABLENAME T2 ON T1.PK = T2.PK 
where
   T1.field1 = @someParameter

Clearly if your TABLENAME table contains a large amount of data, this will go across the network too and performance might be poor. On the other hand, for a small amount of data, this works well and avoids the dynamic sql construction overheads (sql injection, escaping quotes) that an exec approach might require.

According to this site add

CONFIG += c++11

to your .pro file (see at the bottom of that web page). It requires Qt 5.

The other answers, suggesting

QMAKE_CXXFLAGS += -std=c++11 (or QMAKE_CXXFLAGS += -std=c++0x)

also work with Qt 4.8 and gcc / clang.

Regarding :: there is another Stackoverflow entry which covers the :: case. In short, it is used to construct Lists by 'consing' a head element and a tail list. It is both a class which represents a cons'ed list and which can be used as an extractor, but most commonly it is a method on a list. As Pablo Fernandez points out, since it ends in a colon, it is right associative, meaning the receiver of the method call is to the right, and the argument to the left of the operator. That way you can elegantly express the consing as prepending a new head element to an existing list:

val x = 2 :: 3 :: Nil  // same result as List(2, 3)
val y = 1 :: x         // yields List(1, 2, 3)

This is equivalent to

val x = Nil.::(3).::(2) // successively prepend 3 and 2 to an empty list
val y = x.::(1)         // then prepend 1

The use as extractor object is as follows:

def extract(l: List[Int]) = l match {
   case Nil          => "empty"
   case head :: Nil  => "exactly one element (" + head + ")"
   case head :: tail => "more than one element"
}

extract(Nil)          // yields "empty"
extract(List(1))      // yields "exactly one element (1)"
extract(List(2, 3))   // yields "more than one element"

This looks like an operator here, but it is really just another (more readable) way of writing

def extract2(l: List[Int]) = l match {
   case Nil            => "empty"
   case ::(head, Nil)  => "exactly one element (" + head + ")"
   case ::(head, tail) => "more than one element"
}

You can read more about extractors in this post.

1. Connect to your SQL server instance using management studio
2. Goto Security -> Logins -> (RIGHT CLICK) New Login
3. fill in user details
4. Under User Mapping, select the databases you want the user to be able to access and configure

UPDATE:

You'll also want to goto Security -> Server Roles, and for public check the permissions for TSQL Default TCP/TSQL Default VIA/TSQL Local Machine/TSQL Named Pipesand remove the connect permission

An alternate solution using the JsonProperty attribute:

[JsonProperty(NullValueHandling=NullValueHandling.Ignore)]
// or
[JsonProperty("property_name", NullValueHandling=NullValueHandling.Ignore)]

// or for all properties in a class
[JsonObject(ItemNullValueHandling = NullValueHandling.Ignore)]

As seen in this online doc.

Switch is generally faster than a long list of ifs because the compiler can generate a jump table. The longer the list, the better a switch statement is over a series of if statements.

You could use assign, but using assign (or get) is often a symptom of a programming structure that is not very R like. Typically, lists or matrices allow cleaner solutions.

• with a list:

  A <- lapply (1 : 10, function (x) d + rnorm (3))
  

• with a matrix:

  A <- matrix (rep (d, each = 10) + rnorm (30), nrow = 10)
  

You need also to set .min-height: 0px; please see bellow:

.navbar-inner {
    min-height: 0px;
}

.navbar-brand,
.navbar-nav li a {
    line-height: 150px;
    height: 150px;
    padding-top: 0;
}

If you set .min-height: 0px; then you can choose any height you want!

Good Luck!

Maybe it's too late but i found a solution:

You have to edit in the build.gradle either the compileSdkVersion --> to lastest (now it is 28). Like that:

android {
compileSdkVersion 28
defaultConfig {
    applicationId "NAME_OF_YOUR_PROJECT_DIRECTORY"
    minSdkVersion 21
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}

or you can change the version of implementation:

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    api 'com.android.support:design:27.+'
    implementation 'com.android.support:appcompat-v7:27.1.1'
    implementation 'com.android.support.constraint:constraint-layout:1.1.2'
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

As myJSON is an object you can just set its properties, for example:

myJSON.list1 = ["1","2"];

If you dont know the name of the properties, you have to use the array access syntax:

myJSON['list'+listnum] = ["1","2"];

If you want to add an element to one of the properties, you can do;

myJSON.list1.push("3");

You need only to write:

GRANT DBA TO NewDBA;

Because this already makes the user a DB Administrator

To update this question:

For those using Swift checkout this drag and drop swift implementation by Mihai Costea supporting access groups:

https://github.com/macostea/KeychainItemWrapper.swift/blob/master/KeychainItemWrapper.swift

Before using the keychain: consider twice before storing passwords. In many cases storing an authentication token (such as a persistence session id) and the email or account name might be enough. You can easily invalidate authentication tokens to block unauthorized access, requiring the user to login again on the compromised device but not requiring reset password and having to login again on all devices (we are not only using Apple are we?).

The path module does not provide a synchronous version of path.exists so you have to trick around with the fs module.

Fastest thing I can imagine is using fs.realpathSync which will throw an error that you have to catch, so you need to make your own wrapper function with a try/catch.

This error can be due to many many things.

The key here seems the hint about error reading. I see you are working on a flash drive or something similar? Try to run the install on a local folder owned by your current user.

You could also try with sudo, that might solve a permission problem if that's the case.

Another reason why it cannot read could be because it has not downloaded correctly, or saved correctly. A little problem in your network could have caused that, and the cache clean would remove the files and force a refetch but that does not solve your problem. That means it would be more on the save part, maybe it didn't save because of permissions, maybe it didn't not save correctly because it was lacking disk space...

String: A String object is called immutable (read-only) because its value cannot be modified once it has been created. Methods that appear to modify a String object actually return a new String object that contains the modification. If it is necessary to modify the actual contents of a string-like object

string: The string type represents a sequence of zero or more Unicode characters. string is an alias for String in the .NET Framework. string is the intrinsic C# datatype, and is an alias for the system provided type "System.String". The C# specification states that as a matter of style the keyword (string) is preferred over the full system type name (System.String, or String). Although string is a reference type, the equality operators (== and !=) are defined to compare the values of string objects, not references. This makes testing for string equality more intuitive. For example:

Difference between string & String:

• The string is usually used for declaration while String is used for accessing static string methods
• You can use 'string' do declare fields, properties etc that use the predefined type 'string', since the C# specification tells me this is good style.
• You can use 'String' to use system-defined methods, such as String.Compare etc. They are originally defined on 'System.String', not 'string'. 'string' is just an alias in this case.
• You can also use 'String' or 'System.Int32' when communicating with other system, especially if they are CLR-compliant. i.e. - if I get data from elsewhere, I'd de-serialize it into a System.Int32 rather than an 'int', if the origin by definition was something else than a C# system.

Using Xcode 7.3, I spent way too much time trying to figure this out -- none of the answers here or elsewhere did the trick -- and ultimately stumbled into a ridiculously easy solution.

1. In the Xcode preferences team settings, delete all provisioning profiles as mentioned in several other answers. I do this with right click, "Show in Finder," Command+A, delete -- it seems these details have changed over different Xcode versions.
2. Do not re-download any profiles. Instead, exit your preferences and rebuild your project (I built it for my connected iPhone). A little while into the build sequence there will be an alert informing you no provisioning profiles were found, and it will ask if you want this to be fixed automatically. Choose to fix it automatically.
3. After Xcode does some stuff, you will magically have a new provisioning profile providing what your app needs. I have since uploaded my app for TestFlight and it works great.

Hope this helps someone.

Changing your css file to a scss file would allow you to do the trick. An example in Angular would be to use an ngClass and your scss would look like:

 .sidebar {
    height: 100%;
    width: 60px;

    &.is-open {
        width: 150px
    }
} 

The problem here is that your timer starts a thread and when it runs the callback function, the callback function ( updatelistview) is accessing controls on UI thread so this can not be done becuase of this

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Wrap the code within $(document).ready(function(){...........}); handler , also remove the ; after if

$(document).ready(function(){
    $('#purpose').on('change', function() {
      if ( this.value == '1')
      //.....................^.......
      {
        $("#business").show();
      }
      else
      {
        $("#business").hide();
      }
    });
});

From reading the socket.io source code it looks like the "listen" method takes arguments (server, options, fn) and if "server" is an instance of an HTTP/S server it will simply wrap it for you.

So you could presumably give it an empty server which listens for the 'connection' event and handles the socket remoteAddress; however, things might be very difficult if you need to associate that address with an actual socket.io Socket object.

var http = require('http')
  , io = require('socket.io');
io.listen(new http.Server().on('connection', function(sock) {
  console.log('Client connected from: ' + sock.remoteAddress);
}).listen(80));

Might be easier to submit a patch to socket.io wherein their own Socket object is extended with the remoteAddress property assigned at connection time...

Since you've asked to read and modify the xls file I have changed @mj82's answer to correspond your needs.

HSSFWorkbook does not have Save method, but it does have Write to a stream.

static void Main(string[] args)
        {
            string filepath = @"C:\test.xls";

            HSSFWorkbook hssfwb;

            using (FileStream file = new FileStream(filepath, FileMode.Open, FileAccess.Read))
            {
                hssfwb = new HSSFWorkbook(file);
            }

            ISheet sheet = hssfwb.GetSheetAt(0);

            for (int row = 0; row <= sheet.LastRowNum; row++)
            {
                if (sheet.GetRow(row) != null) //null is when the row only contains empty cells 
                {
                    // Set new cell value
                    sheet.GetRow(row).GetCell(0).SetCellValue("foo");
                    Console.WriteLine("Row {0} = {1}", row, sheet.GetRow(row).GetCell(0).StringCellValue);

The Getting Started Way

Toast.makeText(this, "Hello World", Toast.LENGTH_SHORT).show();

when you use const in the method signature (like your said: const char* foo() const;) you are telling the compiler that memory pointed to by this can't be changed by this method (which is foo here).

Simply because CPU/ABI says "No system images installed for this target". You need to install system images.

In the Android SDK Manager check that you have installed "ARM EABI v7a System Image" (for each Android version from 4.0 and on you have to install a system image to be able to run a virtual device)

In your case only ARM system image exsits (Android 4.2). If you were running an older version, Intel has provided System Images (Intel x86 ATOM). You can check on the internet to see the comparison in performance between both.

In my case (see image below) I haven't installed a System Image for Android 4.2, whereas I have installed ARM and Intel System Images for 4.1.2

As long as I don't install the 4.2 System Image I would have the same problem as you.

UPDATE : This recent article Speeding Up the Android Emaulator on Intel Architectures explains how to use/install correctly the intel system images to speed up the emulator.

EDIT/FOLLOW UP

What I show in the picture is for Android 4.2, as it was the original question, but is true for every versions of Android.

Of course (as @RedPlanet said), if you are developing for MIPS CPU devices you have to install the "MIPS System Image".

Finally, as @SeanJA said, you have to restart eclipse to see the new installed images. But for me, I always restart a software which I updated to be sure it takes into account all the modifications, and I assume it is a good practice to do so.

This is the PHP ternary operator (also known as a conditional operator) - if first operand evaluates true, evaluate as second operand, else evaluate as third operand.

Think of it as an "if" statement you can use in expressions. Can be very useful in making concise assignments that depend on some condition, e.g.

$param = isset($_GET['param']) ? $_GET['param'] : 'default';

There's also a shorthand version of this (in PHP 5.3 onwards). You can leave out the middle operand. The operator will evaluate as the first operand if it true, and the third operand otherwise. For example:

$result = $x ?: 'default';

It is worth mentioning that the above code when using i.e. $_GET or $_POST variable will throw undefined index notice and to prevent that we need to use a longer version, with isset or a null coalescing operator which is introduced in PHP7:

$param = $_GET['param'] ?? 'default';

You can use the form reference which exists on all inputs, this is much faster than .closest() (5-10 times faster in Chrome and IE8). Works on IE6 & 7 too.

var input = $('input[type=submit]');
var form = input.length > 0 ? $(input[0].form) : $();

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

Make a bypass API in server.js. This works for me.

app.post('/by-pass-api',function(req, response){
  const url = req.body.url;
  console.log("calling url", url);
  request.get(
    url,
    (error, res, body) => {
      if (error) {
        console.error(error)
        return response.status(200).json({'content': "error"}) 
}
        return response.status(200).json(JSON.parse(body))
        },
      )
    })

And call it using axios or fetch like this:

const options = {
     method: 'POST',
     headers: {'content-type': 'application/json'},
     url:`http://localhost:3000/by-pass-api`, // your environment 
     data: { url },  // your https request here
    };

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy() (or .values for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.

For example, you can use ndarray.max() along the first axis.

# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
   A  B
0  1 -2
1  2  8
2  3  1

df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns, 
# df['C'] = df.values.max(1) 
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

If your data has NaNs, you will need numpy.nanmax:

df['C'] = np.nanmax(df.values, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

You can also use numpy.maximum.reduce. numpy.maximum is a ufunc (Universal Function), and every ufunc has a reduce:

df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

np.maximum.reduce and np.max appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).

The graph was generated using perfplot. Benchmarking code, for reference:

import pandas as pd
import perfplot

np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))

perfplot.show(
    setup=lambda n: pd.concat([df_] * n, ignore_index=True),
    kernels=[
        lambda df: df.assign(new=df.max(axis=1)),
        lambda df: df.assign(new=df.values.max(1)),
        lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
        lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
    ],
    labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],
    n_range=[2**k for k in range(0, 15)],
    xlabel='N (* len(df))',
    logx=True,
    logy=True)

Using a set to store the word list because looking them up will be faster:

with open("english_words.txt") as word_file:
    english_words = set(word.strip().lower() for word in word_file)

def is_english_word(word):
    return word.lower() in english_words

print is_english_word("ham")  # should be true if you have a good english_words.txt

To answer the second part of the question, the plurals would already be in a good word list, but if you wanted to specifically exclude those from the list for some reason, you could indeed write a function to handle it. But English pluralization rules are tricky enough that I'd just include the plurals in the word list to begin with.

As to where to find English word lists, I found several just by Googling "English word list". Here is one: http://www.sil.org/linguistics/wordlists/english/wordlist/wordsEn.txt You could Google for British or American English if you want specifically one of those dialects.

Problem is in the for loop in the code snippet:
for (i > 0; i--;)

Here, your intention seems to be entering the loop if (i > 0) and decrement the value of i by one after the completion of for loop.

Does it work like that? lets see.

Look at the for() loop syntax:

**for ( initialization; condition check; increment/decrement ) {  
    statements;  
}**

Initialization gets executed only once in the beginning of the loop. Pay close attention to ";" in your code snippet and map it with for loop syntax.

Initialization : i > 0 : Gets executed only once. Doesn't have any impact in your code.

Condition check : i -- : post decrement.

              Here, i is used for condition check and then it is decremented. 
              Decremented value will be used in statements within for loop. 
              This condition check is working as increment/decrement too in your code. 

Lets stop here and see floating point exception.

what is it? One easy example is Divide by 0. Same is happening with your code.

When i reaches 1 in condition check, condition check validates to be true.
Because of post decrement i will be 0 when it enters for loop.

Modulo operation at line #9 results in divide by zero operation.  

With this background you should be able to fix the problem in for loop.

My suggestion is to run

openssl enc -aes-256-cbc -in plain.txt -out encrypted.bin

under debugger and see what exactly what it is doing. openssl.c is the only real tutorial/getting started/reference guide OpenSSL has. All other documentation is just an API reference.

U1: My guess is that you are not setting some other required options, like mode of operation (padding).

U2: this is probably a duplicate of this question: AES CTR 256 Encryption Mode of operation on OpenSSL and answers there will likely help.

Note that -p is an argument to the mkdir command specifically, not the whole of Unix. Every command can have whatever arguments it needs.

In this case it means "parents", meaning mkdir will create a directory and any parents that don't already exist.

Use a comma to specify two (or more) different rules:

@media screen and (max-width: 995px), 
       screen and (max-height: 700px) {
  ...
}

From https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries

Commas are used to combine multiple media queries into a single rule. Each query in a comma-separated list is treated separately from the others. Thus, if any of the queries in a list is true, the entire media statement returns true. In other words, lists behave like a logical or operator.

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu". Once this is done, you can open an admin powershell window via Win+X,A or by right-clicking on the start button and selecting "Windows Powershell (Admin)":

Here's where you replace the "Command Prompt" option with a "Windows Powershell" option:

transform: scale(0.5);

Example:

<div>Normal</div>
<div class="scaled">Scaled</div>

div {
  width: 80px;
  height: 80px;
  background-color: skyblue;
}

.scaled {
  transform: scale(0.7); /* Equal to scaleX(0.7) scaleY(0.7) */
  background-color: pink;
}

see: https://developer.mozilla.org/en-US/docs/Web/CSS/transform-function/scale

In your code $this->uri->segment(3) refers to the pagination offset which you use in your query. According to your $config['base_url'] = base_url().'index.php/papplicant/viewdeletedrecords/' ;, $this->uri->segment(3) i.e segment 3 refers to the offset. The first segment is the controller, second is the method, there after comes the parameters sent to the controllers as segments.

Here's my solution:

public static class EnumerationExtensions
{
    public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            yield break;

        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int last = inputList.Count;
            int first = last - count;

            if (first < 0)
                first = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Use a ring buffer. We have to enumerate the input, and we don't know in advance how many elements it will contain.
            T[] buffer = new T[count];

            int index = 0;

            count = 0;

            foreach (T item in input)
            {
                buffer[index] = item;

                index = (index + 1) % buffer.Length;
                count++;
            }

            // The index variable now points at the next buffer entry that would be filled. If the buffer isn't completely
            // full, then there are 'count' elements preceding index. If the buffer *is* full, then index is pointing at
            // the oldest entry, which is the first one to return.
            //
            // If the buffer isn't full, which means that the enumeration has fewer than 'count' elements, we'll fix up
            // 'index' to point at the first entry to return. That's easy to do; if the buffer isn't full, then the oldest
            // entry is the first one. :-)
            //
            // We'll also set 'count' to the number of elements to be returned. It only needs adjustment if we've wrapped
            // past the end of the buffer and have enumerated more than the original count value.

            if (count < buffer.Length)
                index = 0;
            else
                count = buffer.Length;

            // Return the values in the correct order.
            while (count > 0)
            {
                yield return buffer[index];

                index = (index + 1) % buffer.Length;
                count--;
            }
        }
    }

    public static IEnumerable<T> SkipLast<T>(this IEnumerable<T> input, int count)
    {
        if (count <= 0)
            return input;
        else
            return input.SkipLastIter(count);
    }

    private static IEnumerable<T> SkipLastIter<T>(this IEnumerable<T> input, int count)
    {
        var inputList = input as IList<T>;

        if (inputList != null)
        {
            int first = 0;
            int last = inputList.Count - count;

            if (last < 0)
                last = 0;

            for (int i = first; i < last; i++)
                yield return inputList[i];
        }
        else
        {
            // Aim to leave 'count' items in the queue. If the input has fewer than 'count'
            // items, then the queue won't ever fill and we return nothing.

            Queue<T> elements = new Queue<T>();

            foreach (T item in input)
            {
                elements.Enqueue(item);

                if (elements.Count > count)
                    yield return elements.Dequeue();
            }
        }
    }
}

The code is a bit chunky, but as a drop-in reusable component, it should perform as well as it can in most scenarios, and it'll keep the code that's using it nice and concise. :-)

My TakeLast for non-IList`1 is based on the same ring buffer algorithm as that in the answers by @Mark Byers and @MackieChan further up. It's interesting how similar they are -- I wrote mine completely independently. Guess there's really just one way to do a ring buffer properly. :-)

Looking at @kbrimington's answer, an additional check could be added to this for IQuerable<T> to fall back to the approach that works well with Entity Framework -- assuming that what I have at this point does not.

I know it's an old question, but for everyone on google ending up here looking for information on how to deal with blocking and non-blocking sockets here is an in depth explanation of the different ways how to deal with the I/O modes of sockets - http://dwise1.net/pgm/sockets/blocking.html.

Quick summary:

• So Why do Sockets Block?

• What are the Basic Programming Techniques for Dealing with Blocking Sockets?

  • Have a design that doesn't care about blocking
  • Using select
  • Using non-blocking sockets.
  • Using multithreading or multitasking

Something like that happened to me when I made copies of structures to temporary tables, so I removed the not null.

DECLARE
   CURSOR cur_temp_not_null IS
        SELECT table_name, constraint_name  FROM all_constraints WHERE table_name LIKE 'TEMP_%' AND  owner='myUSUARIO';

   V_sql VARCHAR2(200); 

BEGIN
  FOR c_not_null IN cur_temp_not_null
   LOOP
     v_sql :='ALTER TABLE ' || c_not_null.table_name || ' DROP CONSTRAINT '|| c_not_null.constraint_name;
     EXECUTE IMMEDIATE  v_sql;     
  END LOOP;
END;

You can use .Length == 0 if the length is empty and the array exists, but are you sure it's not null?

This is because you're using getActivity() inside an inner class. Try using:

SherlockFragmentActivity.this.getActivity()

instead, though there's really no need for the getActivity() part. In your case, SherlockFragmentActivity .this should suffice.

I think agileguy has the correct answer, but I would like to add that for more difficult situations there are a couple of strategies I take to solve the problem. The first is to use a truth table. If you Google "truth table" you will run across some examples related directly to programming and computer science.

Another strategy I take is to use an anonymous function to encapsulate common logic between various conditions. Create it right before the if block, then use it where needed. This seems to create code that is more readable and maintainable.

int cannot be null. If you are not assigning any value to int default value will be 0. If you want to check for null then make int as Integer in declaration. Then Integer object can be null. So, you can check where it is null or not. Even in javax bean validation you won't be able to get error for @NotNull annotation until the variable is declared as Integer.

An alternative to javax.comm is the rxtx library which supports more platforms than javax.comm.

I had the same problem. solved it like this:

return new ModelAndView("redirect:/user/list?success=true");

And then my controller method look like this:

public ModelMap list(@RequestParam(required=false) boolean success) {
    ModelMap mm = new ModelMap();
    mm.put(SEARCH_MODEL_KEY, campaignService.listAllCampaigns());
    if(success)
        mm.put("successMessageKey", "campaign.form.msg.success");
    return mm;
}

Works perfectly unless you want to send simple data, not collections let's say. Then you'd have to use session I guess.

You can find an example below. Basically you attach a function to window's scroll event and trace scrollTop property and if it's higher than desired threshold you apply position: fixed and some other css properties.

jQuery(function($) {_x000D_
  $(window).scroll(function fix_element() {_x000D_
    $('#target').css(_x000D_
      $(window).scrollTop() > 100_x000D_
        ? { 'position': 'fixed', 'top': '10px' }_x000D_
        : { 'position': 'relative', 'top': 'auto' }_x000D_
    );_x000D_
    return fix_element;_x000D_
  }());_x000D_
});

body {_x000D_
  height: 2000px;_x000D_
  padding-top: 100px;_x000D_
}_x000D_
code {_x000D_
  padding: 5px;_x000D_
  background: #efefef;_x000D_
}_x000D_
#target {_x000D_
  color: #c00;_x000D_
  font: 15px arial;_x000D_
  padding: 10px;_x000D_
  margin: 10px;_x000D_
  border: 1px solid #c00;_x000D_
  width: 200px;_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="target">This <code>div</code> is going to be fixed</div>

I have the same issue. It seems that pip is the problem. Try

pip uninstall xlsxwriter
easy_install xlsxwriter

I've preferred using the params filter for parameter-centric content-type.. I believe that should work in conjunction with the produces attribute.

@GetMapping(value="/person/{id}/", 
            params="format=json",
            produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Person> getPerson(@PathVariable Integer id){
    Person person = personMapRepository.findPerson(id);
    return ResponseEntity.ok(person);
} 
@GetMapping(value="/person/{id}/", 
            params="format=xml",
            produces=MediaType.APPLICATION_XML_VALUE)
public ResponseEntity<Person> getPersonXML(@PathVariable Integer id){
    return GetPerson(id); // delegate
}

You can call CREATE Function near the beginning of your script and DROP Function near the end.

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

If you want the number to always be positive no matter what you can do this.

function toPositive(n){
    if(n < 0){
        n = n * -1;
    }
    return n;
}
var a = toPositive(2);  // 2
var b = toPositive(-2); // 2

You could also try this, but i don't recommended it:

function makePositive(n){
    return Number((n*-n).toString().replace('-','')); 
}
var a = makePositive(2);  // 2
var b = makePositive(-2); // 2

The problem with this is that you could be changing the number to negative, then converting to string and removing the - from the string, then converting back to int. Which I would guess would take more processing then just using the other function.

I have tested this in php and the first function is faster, but sometimes JS does some crazy things, so I can't say for sure.
