If you have a std::wstring object, you can call c_str() on it to get a wchar_t*:

std::wstring name( L"Steve Nash" );
const wchar_t* szName = name.c_str();

Since you are operating on a narrow string, however, you would first need to widen it. There are various options here; one is to use Windows' built-in MultiByteToWideChar routine. That will give you an LPWSTR, which is equivalent to wchar_t*.

This code works in Linux (C++11, geany, g++ 7.4.0):

#include <iostream>

Following is the example code for how to use foreach in golang

package main

import (
    "fmt"
)

func main() {

    arrayOne := [3]string{"Apple", "Mango", "Banana"}

    for index,element := range arrayOne{

        fmt.Println(index)
        fmt.Println(element)        

    }   

}

This is a running example https://play.golang.org/p/LXptmH4X_0

Is this what you are looking for?

https://maps.googleapis.com/maps/api/place/search/xml?location=49.260691,-123.137784&radius=500&sensor=false&key=*PlacesAPIKey*&types=restaurant

types is optional

You can use:

window.location.href = '/Branch/Details/' + id;

But your Ajax code is incomplete without success or error functions.

You are not supposed to assign it to any variable, when you append something in the list, it updates automatically. use only:-

last_list.append(p.last)

if you assign this to a variable "last_list" again, it will no more be a list (will become a none type variable since you haven't declared the type for that) and append will become invalid in the next run.

Try preventing the default behaviour if you don't like the incoming key value:

document.querySelector("input").addEventListener("keypress", function (evt) {
    if (evt.which < 48 || evt.which > 57)
    {
        evt.preventDefault();
    }
});

I had this same issue with my windows 10 machine, I tried many solutions but nor worked until I installed the latest git version. https://git-scm.com/downloads.

Others have answered your earlier question. For this:

As an addendum, is there any way to extract directly with the header names rather than with column numbers?

I haven't tried it, but you could store each header's index in a hash and then use that hash to get its index later on.

for(i=0;i<$NF;i++){
    hash[$i] = i;
}

Then later on, use it:

j = hash["header1"];
print $j;

If you don't do anything in your bash script than run the php one, you could simply run the php script from cron with a command like /usr/bin/php /path/to/your/file.php.

<td><b>Field Label:</b><br>
    <select style='align:left; width:100%;' id='some_id' name='some_name'>
    <option hidden selected>Select one...</option>
    <option value='Value1'>OptLabel1</option>
    <option value='Value2'>OptLabel2</option>
    <option value='Value3'>OptLabel3</option></select>
</td>

Just put "hidden" on option you want to hide on dropdown list.

It's too late to answer this question, but it could help for new readers, It seems version issues. I ran all these tests with spring 4.1.4 and found that the order of @RequestBody and @RequestParam doesn't matter.

1. same as your result
2. same as your result
3. gave body= "name=abc", and name = "abc"
4. Same as 3.
5. body ="name=abc", name = "xyz,abc"
6. same as 5.

Here's my work around for this I hope it helps :

<TouchableOpacity
    onPress={() => {
        this.onSubmit()
    }}
    disabled={this.state.validity}
    style={this.state.validity ?
          SignUpStyleSheet.inputStyle :
          [SignUpStyleSheet.inputAndButton, {opacity: 0.5}]}>
    <Text style={SignUpStyleSheet.buttonsText}>Sign-Up</Text>
</TouchableOpacity>

in SignUpStyleSheet.inputStyle holds the style for the button when it disabled or not, then in style={this.state.validity ? SignUpStyleSheet.inputStyle : [SignUpStyleSheet.inputAndButton, {opacity: 0.5}]} I add the opacity property if the button is disabled.

You can use this, it's working for me and is extremely simple solution.

If the both DBs(from & to) are password protected, in that scenario terminal won't ask for the password for both the DBs, password prompt will appear only once. So, to fix this, pass the password along with the commands.

PGPASSWORD=<password> pg_dump -h <hostIpAddress> -U <hostDbUserName> -t <hostTable> > <hostDatabase> | PGPASSWORD=<pwd> psql -h <toHostIpAddress> -d <toDatabase> -U <toDbUser>

I was searching for a fix on this and the folder i was ADD or COPY'ing was not in the build folder, multiple directories above or referenced from /

Moving the folder from outside the build folder into the build folder fixed my issue.

import json
with open('result.json', 'w') as fp:
    json.dump(sample, fp)

This is an easier way to do it.

In the second line of code the file result.json gets created and opened as the variable fp.

In the third line your dict sample gets written into the result.json!

Reference docs of docker: https://docs.docker.com/install/linux/linux-postinstall/#configure-where-the-docker-daemon-listens-for-connections

There are 2 ways in configuring the docker daemon port

1) Configuring at /etc/default/docker file:

DOCKER_OPTS="-H tcp://127.0.0.1:5000 -H unix:///var/run/docker.sock"

2) Configuring at /etc/docker/daemon.json:

{
"debug": true,
"hosts": ["tcp://127.0.0.1:5000", "unix:///var/run/docker.sock"]
}

If the docker default socket is not configured Docker will wait for infinite period.i.e

Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock
Waiting for /var/run/docker.sock

NOTE : BUT DON'T CONFIGURE IN BOTH THE CONFIGURATION FILES, the following error may occur :

Waiting for /var/run/docker.sock
unable to configure the Docker daemon with file /etc/docker/daemon.json: the following directives are specified both as a flag and in the configuration file: hosts: (from flag: [tcp://127.0.0.1:5000 unix:///var/run/docker.sock], from file: tcp://127.0.0.1:5000)

The reason for adding both the user port[ tcp://127.0.0.1:5000] and default docker socket[unix:///var/run/docker.sock] is that the user port enables the access to the docker APIs whereas the default socket enables the CLI. In case the default port[unix:///var/run/docker.sock] is not mentioned in /etc/default/docker file the following error may occur:

# docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This error is not because that the docker is not running, but because of default docker socket is not enabled.

Once the configuration is enabled restart the docker service and verify the docker port is enabled or not:

# netstat -tunlp | grep -i 5000
tcp        0      0 127.0.0.1:5000          0.0.0.0:*               LISTEN      31661/dockerd 

Applicable for Docker Version 17.04, may vary with different versions of docker.

unless you have an explicit reason to choose the Apache HttpClient, you should prefer java.net.URLConnection. you can find plenty of examples of how to use it on the web.

we've also improved the Android documentation since your original post: http://developer.android.com/reference/java/net/HttpURLConnection.html

and we've talked about the trade-offs on the official blog: http://android-developers.blogspot.com/2011/09/androids-http-clients.html

The scanner can also use delimiters other than whitespace.

Easy example from Scanner API:

 String input = "1 fish 2 fish red fish blue fish";

 // \\s* means 0 or more repetitions of any whitespace character 
 // fish is the pattern to find
 Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");

 System.out.println(s.nextInt());   // prints: 1
 System.out.println(s.nextInt());   // prints: 2
 System.out.println(s.next());      // prints: red
 System.out.println(s.next());      // prints: blue

 // don't forget to close the scanner!!
 s.close(); 

The point is to understand the regular expressions (regex) inside the Scanner::useDelimiter. Find an useDelimiter tutorial here.

To start with regular expressions here you can find a nice tutorial.

Random number generators are not actually random, they like most software is completely predictable. What rand does is create a different pseudo-random number each time it is called One which appears to be random. In order to use it properly you need to give it a different starting point.

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

int main ()
{
  /* initialize random seed: */
  srand ( time(NULL) );

  printf("random number %d\n",rand());
  printf("random number %d\n",rand());
  printf("random number %d\n",rand());
  printf("random number %d\n",rand());

  return 0;
}

Try this:

max.setOnKeyListener(new OnKeyListener(){
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event){
        if(keyCode == event.KEYCODE_ENTER){
            //do what you want
        }
    }
});

How about this code?

$("a.save#country")

A solution for Nuget 3.2 on Visual Studio 2015 is:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <config>
        <add key="repositoryPath" value="../lib" />
    </config>
</configuration>

Using forward slash for parent folder. Save above file (nuget.config) in solution folder.

You can load a page like this :

let url: URL = URL(string:"https://google.com")!
webView.loadRequest(URLRequest.init(url: url))

Or the one-line approach :

webView.loadRequest(URLRequest.init(url: URL(string: "https://google.com")!))

webView is your outlet var.

As a general rule, I declare my variables in the inner-most possible scope. So, if you're not using intermediateResult outside of the loop, then I'd go with B.

Eric's answer is great, but you really don't need that timeout. If you're using jQuery, you can just wait for the page to load. So I'd suggest changing the code to:

// The function actually applying the offset
function offsetAnchor() {
    if (location.hash.length !== 0) {
        window.scrollTo(window.scrollX, window.scrollY - 100);
    }
}

// This will capture hash changes while on the page
$(window).on("hashchange", function () {
    offsetAnchor();
});

// Let the page finish loading.
$(document).ready(function() {
    offsetAnchor();
});

This also gets us rid of that arbitrary factor.

I was having the same problem and none if these worked for me. Here is what did work though...

app.factory('myService', function($http) {
    var data = function (value) {
            return $http.get(value);
    }

    return { data: data }
});

and then the function that uses it is...

vm.search = function(value) {

        var recieved_data = myService.data(value);

        recieved_data.then(
            function(fulfillment){
                vm.tags = fulfillment.data;
            }, function(){
                console.log("Server did not send tag data.");
        });
    };

The service isn't that necessary but I think its a good practise for extensibility. Most of what you will need for one will for any other, especially when using APIs. Anyway I hope this was helpful.

1. verify if gradle.properties define right one JAVA_HOVE

   org.gradle.java.home=C:\Program Files (x86)\Java\jdk1.8.0_181

or

2. if it's not defined be sure if Eclipse know JDK and not JRE

The reason "sign" is not included is that if we included every useful one-liner in the list of built-in functions, Python wouldn't be easy and practical to work with anymore. If you use this function so often then why don't you do factor it out yourself? It's not like it's remotely hard or even tedious to do so.

For me, I had side-sync enabled and active. Closing it imediately made the issue go away. It might be worth closing this or any other communication between PC and device

Using you current code, make this tweak:

public void listf(String directoryName, List<File> files) {
    File directory = new File(directoryName);

    // Get all files from a directory.
    File[] fList = directory.listFiles();
    if(fList != null)
        for (File file : fList) {      
            if (file.isFile()) {
                files.add(file);
            } else if (file.isDirectory()) {
                listf(file.getAbsolutePath(), files);
            }
        }
    }
}

Yes, set the cell as a RANGE object one time and then use that RANGE object in your code:

Sub RangeExample()
Dim MyRNG As Range

Set MyRNG = Sheets("Sheet1").Cells(23, 4)

Debug.Print MyRNG.Value

End Sub

Alternately you can simply store the value of that cell in memory and reference the actual value, if that's all you really need. That variable can be Long or Double or Single if numeric, or String:

Sub ValueExample()
Dim MyVal As String

MyVal = Sheets("Sheet1").Cells(23, 4).Value

Debug.Print MyVal

End Sub

Please try this.

As you can see the evolution is insane, about 560 time faster than reported in 2012.

On my machines and servers, following my numerous experiments, basics for loops are the fastest. This is even clearer using nested loops ($i $j $k..)

It is also the most flexible in usage, and has a better readability from my view.

Here's another way to drop a default constraint with an unknown name without having to first run a separate query to get the constraint name:

DECLARE @ConstraintName nvarchar(200)
SELECT @ConstraintName = Name FROM SYS.DEFAULT_CONSTRAINTS
WHERE PARENT_OBJECT_ID = OBJECT_ID('__TableName__')
AND PARENT_COLUMN_ID = (SELECT column_id FROM sys.columns
                        WHERE NAME = N'__ColumnName__'
                        AND object_id = OBJECT_ID(N'__TableName__'))
IF @ConstraintName IS NOT NULL
EXEC('ALTER TABLE __TableName__ DROP CONSTRAINT ' + @ConstraintName)

It's been a while but for future reference: the method shouldComponentUpdate() can be used.

An update can be caused by changes to props or state. These methods are called in the following order when a component is being re-rendered:

static getDerivedStateFromProps() 
shouldComponentUpdate() 
render()
getSnapshotBeforeUpdate() 
componentDidUpdate()

You can open your test file in VSCode and click on one of those options.

PORT 4369: Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. Nodes must be able to reach each other and the port mapper daemon for clustering to work.

PORT 35197 set by inet_dist_listen_min/max Firewalls must permit traffic in this range to pass between clustered nodes

RabbitMQ Management console:

• PORT 15672 for RabbitMQ version 3.x
• PORT 55672 for RabbitMQ pre 3.x

PORT 5672 RabbitMQ main port.

For a cluster of nodes, they must be open to each other on 35197, 4369 and 5672.

For any servers that want to use the message queue, only 5672 is required.

It isn't that hard to deal with the character array itself without converting the array to a string. Especially in the case where the length of the character array is know or can be easily found. With the character array, the length must be determined in the same scope as the array definition, e.g.:

size_t len sizeof myarray/sizeof *myarray;

For strings you, of course, have strlen available.

With the length known, regardless of whether it is a character array or a string, you can convert the character values to a number with a short function similar to the following:

/* convert character array to integer */
int char2int (char *array, size_t n)
{    
    int number = 0;
    int mult = 1;

    n = (int)n < 0 ? -n : n;       /* quick absolute value check  */

    /* for each character in array */
    while (n--)
    {
        /* if not digit or '-', check if number > 0, break or continue */
        if ((array[n] < '0' || array[n] > '9') && array[n] != '-') {
            if (number)
                break;
            else
                continue;
        }

        if (array[n] == '-') {      /* if '-' if number, negate, break */
            if (number) {
                number = -number;
                break;
            }
        }
        else {                      /* convert digit to numeric value   */
            number += (array[n] - '0') * mult;
            mult *= 10;
        }
    }

    return number;
}

Above is simply the standard char to int conversion approach with a few additional conditionals included. To handle stray characters, in addition to the digits and '-', the only trick is making smart choices about when to start collecting digits and when to stop.

If you start collecting digits for conversion when you encounter the first digit, then the conversion ends when you encounter the first '-' or non-digit. This makes the conversion much more convenient when interested in indexes such as (e.g. file_0127.txt).

A short example of its use:

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

int char2int (char *array, size_t n);

int main (void) {

    char myarray[4] = {'-','1','2','3'}; 
    char *string = "some-goofy-string-with-123-inside";
    char *fname = "file-0123.txt";

    size_t mlen = sizeof myarray/sizeof *myarray;
    size_t slen = strlen (string);
    size_t flen = strlen (fname);

    printf ("\n myarray[4] = {'-','1','2','3'};\n\n");
    printf ("   char2int (myarray, mlen):  %d\n\n", char2int (myarray, mlen));

    printf (" string = \"some-goofy-string-with-123-inside\";\n\n");
    printf ("   char2int (string, slen) :  %d\n\n", char2int (string, slen));

    printf (" fname = \"file-0123.txt\";\n\n");
    printf ("   char2int (fname, flen)  :  %d\n\n", char2int (fname, flen));

    return 0;
}

Note: when faced with '-' delimited file indexes (or the like), it is up to you to negate the result. (e.g. file-0123.txt compared to file_0123.txt where the first would return -123 while the second 123).

Example Output

$ ./bin/atoic_array

 myarray[4] = {'-','1','2','3'};

   char2int (myarray, mlen):  -123

 string = "some-goofy-string-with-123-inside";

   char2int (string, slen) :  -123

 fname = "file-0123.txt";

   char2int (fname, flen)  :  -123

Note: there are always corner cases, etc. that can cause problems. This isn't intended to be 100% bulletproof in all character sets, etc., but instead work an overwhelming majority of the time and provide additional conversion flexibility without the initial parsing or conversion to string required by atoi or strtol, etc.

Underscore.js is a good library for these sorts of operations - it uses the builtin routines such as Array.filter if available, or uses its own if not.

http://documentcloud.github.com/underscore/

The docs will give an idea of use - the javascript lambda syntax is nowhere near as succinct as ruby or others (I always forget to add an explicit return statement for example) and scope is another easy way to get caught out, but you can do most things quite easily with the exception of constructs such as lazy list comprehensions.

From the docs for .select() (.filter() is an alias for the same)

Looks through each value in the list, returning an array of all the values that pass a truth test (iterator). Delegates to the native filter method, if it exists.

  var evens = _.select([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
  => [2, 4, 6]

This may be an answer (for spring boot 2) and a question at the same time. It seems that in spring boot 2 combined with spring security everything (means every route/antmatcher) is protected by default if you use an individual security mechanism extended from

WebSecurityConfigurerAdapter

If you don´t use an individual security mechanism, everything is as it was?

In older spring boot versions (1.5 and below) as Andy Wilkinson states in his above answer places like public/** or static/** are permitted by default.

So to sum this question/answer up - if you are using spring boot 2 with spring security and have an individual security mechanism you have to exclusivley permit access to static contents placed on any route. Like so:

@Configuration
public class SpringSecurityConfiguration extends WebSecurityConfigurerAdapter {

private final ThdAuthenticationProvider thdAuthenticationProvider;

private final ThdAuthenticationDetails thdAuthenticationDetails;

/**
 * Overloaded constructor.
 * Builds up the needed dependencies.
 *
 * @param thdAuthenticationProvider a given authentication provider
 * @param thdAuthenticationDetails  given authentication details
 */
@Autowired
public SpringSecurityConfiguration(@NonNull ThdAuthenticationProvider thdAuthenticationProvider,
                                   @NonNull ThdAuthenticationDetails thdAuthenticationDetails) {
    this.thdAuthenticationProvider = thdAuthenticationProvider;
    this.thdAuthenticationDetails = thdAuthenticationDetails;
}

/**
 * Creates the AuthenticationManager with the given values.
 *
 * @param auth the AuthenticationManagerBuilder
 */
@Autowired
public void configureGlobal(AuthenticationManagerBuilder auth) {

    auth.authenticationProvider(thdAuthenticationProvider);
}

/**
 * Configures the http Security.
 *
 * @param http HttpSecurity
 * @throws Exception a given exception
 */
@Override
protected void configure(HttpSecurity http) throws Exception {

    http.authorizeRequests()
            .requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()
            .antMatchers("/management/**").hasAnyAuthority(Role.Role_Engineer.getValue(),
            Role.Role_Admin.getValue())
            .antMatchers("/settings/**").hasAnyAuthority(Role.Role_Engineer.getValue(),
            Role.Role_Admin.getValue())

            .anyRequest()
            .fullyAuthenticated()
            .and()
            .formLogin()
            .authenticationDetailsSource(thdAuthenticationDetails)
            .loginPage("/login").permitAll()
            .defaultSuccessUrl("/bundle/index", true)
            .failureUrl("/denied")
            .and()
            .logout()
            .invalidateHttpSession(true)
            .logoutSuccessUrl("/login")
            .logoutUrl("/logout")
            .and()
            .exceptionHandling()
            .accessDeniedHandler(new CustomAccessDeniedHandler());
}

}

Please mind this line of code, which is new:

.requestMatchers(PathRequest.toStaticResources().atCommonLocations()).permitAll()

If you use spring boot 1.5 and below you don´t need to permit these locations (static/public/webjars etc.) explicitly.

Here is the official note, what has changed in the new security framework as to old versions of itself:

Security changes in Spring Boot 2.0 M4

I hope this helps someone. Thank you! Have a nice day!

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

I solved this on Windows 10 by editing an outbound firewall rule. Right click "allow" on rule "Block network access for R local user accounts in SQL Server instance MSSQLSERVER"

Screenshot from Windows 10 Firewall - Outbound rules- this is what was blocking my instance

Another tip to remember: Since v7.0 OpenSSH disables DSS/DSA SSH keys by default due to their inherit weakness. So if you have OpenSSH v7.0+, make sure your key is not ssh-dss.

If you are stuck with DSA keys, you can re-enable support locally by updating your sshd_config and ~/.ssh/config files with lines like so: PubkeyAcceptedKeyTypes=+ssh-dss

use array detect method if you wanted to return first value where block returns true

[1,2,3,11,34].detect(&:even?) #=> 2

OR

[1,2,3,11,34].detect{|i| i.even?} #=> 2

If you wanted to return all values where block returns true then use select

[1,2,3,11,34].select(&:even?)  #=> [2, 34]

You can just substract two date objects.

var d1 = new Date(); //"now"
var d2 = new Date("2011/02/01")  // some date
var diff = Math.abs(d1-d2);  // difference in milliseconds

Since Management Studio 2005 it seems that you can use GO with an int parameter, like:

INSERT INTO mytable DEFAULT VALUES
GO 10

The above will insert 10 rows into mytable. Generally speaking, GO will execute the related sql commands n times.

There are no industry standard definitions for Architect job titles -- Application/System/Software/Solution Architect all refer in general to a senior developer with strong design and leadership skills. The balance of design, strategy, development (often of core services or frameworks) and management differ based on the organization and project.

The only "Architect" job title that really has a different meaning for me is "Enterprise Architect", which I see as more of a IT strategy position.

On newer versions of yum, this information is stored in the "yumdb" when the package is installed. This is the only 100% accurate way to get the information, and you can use:

yumdb search from_repo repoid

(or repoquery and grep -- don't grep yum output). However the command "find-repos-of-install" was part of yum-utils for a while which did the best guess without that information:

http://james.fedorapeople.org/yum/commands/find-repos-of-install.py

As floyd said, a lot of repos. include a unique "dist" tag in their release, and you can look for that ... however from what you said, I guess that isn't the case for you?

You can also use the toBase64Image() method setting animation: false

var options = {
    bezierCurve : false,
    animation: false
};

If value is 9999.988 and Precision 4, scale 2 then it means 9999(it represents precision).99(scale is 2 so .988 is rounded to .99)

If value is 9999.9887 and precision is 4, scale is 2 then it means 9999.99

Same solution via Jquery. Works if you have more than one file input in the page.

$j(".filebutton").click(function() {
    var input = $j(this).next().find('input');
    input.click();
});

$j(".fileinput").change(function(){

    var file = $j(this).val();
    var fileName = file.split("\\");
    var pai =$j(this).parent().parent().prev();
    pai.html(fileName[fileName.length-1]);
    event.preventDefault();
});

 BigDecimal pi = new BigDecimal(3.14);
 BigDecimal pi4 = new BigDecimal(12.56);

 System.out.printf("%.2f",pi);

// prints 3.14

System.out.printf("%.0f",pi4);

// prints 13

Actually you just need to tell doctrine who's your repository class, if you don't, doctrine uses default repo instead of yours.

@ORM\Entity(repositoryClass="Company\NameOfBundle\Repository\NameOfRepository")

Easily create a Table Value Function that will return a table with all dates. Input dates as string You can customize the date in the the format you like '01/01/2017' or '01-01-2017' in string formats (103,126 ...)

Try this

CREATE FUNCTION [dbo].[DateRange_To_Table] ( @minDate_Str NVARCHAR(30), @maxDate_Str NVARCHAR(30))

RETURNS  @Result TABLE(DateString NVARCHAR(30) NOT NULL, DateNameString NVARCHAR(30) NOT NULL)

AS

begin

    DECLARE @minDate DATETIME, @maxDate DATETIME
    SET @minDate = CONVERT(Datetime, @minDate_Str,103)
    SET @maxDate = CONVERT(Datetime, @maxDate_Str,103)


    INSERT INTO @Result(DateString, DateNameString )
    SELECT CONVERT(NVARCHAR(10),@minDate,103), CONVERT(NVARCHAR(30),DATENAME(dw,@minDate))



    WHILE @maxDate > @minDate
    BEGIN
        SET @minDate = (SELECT DATEADD(dd,1,@minDate))
        INSERT INTO @Result(DateString, DateNameString )
        SELECT CONVERT(NVARCHAR(10),@minDate,103), CONVERT(NVARCHAR(30),DATENAME(dw,@minDate))
    END




    return

end   

To execute the function do this:

SELECT * FROM dbo.DateRange_To_Table ('01/01/2017','31/01/2017')

The output will be

01/01/2017  Sunday
02/01/2017  Monday
03/01/2017  Tuesday
04/01/2017  Wednesday

The docs are pretty clear that you pass in a second parameter to specify granularity.

If you want to limit the granularity to a unit other than milliseconds, pass the units as the second parameter.

moment('2010-10-20').isAfter('2010-01-01', 'year'); // false
moment('2010-10-20').isAfter('2009-12-31', 'year'); // true

As the second parameter determines the precision, and not just a single value to check, using day will check for year, month and day.

For your case you would pass 'day' as the second parameter.

enums in C don't really work the way you're expecting them to. You can think of them kind of like glorified constants (with a few additional benefits relating to being a collection of such constants), and the text you've written in for "Sunday" really gets resolved to a number during compilation, the text is ultimately discarded.

In short: to do what you really want you'll need to keep an array of the strings or create a function to map from the enum's value to the text you'd like to print.

Use this code (Opt 1):

    //Opt 1
    Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"),
            Locale.getDefault());
    Date currentLocalTime = calendar.getTime();
    DateFormat date = new SimpleDateFormat("Z", Locale.getDefault());
    String localTime = date.format(currentLocalTime);
    String finalTimezone = String.format("GMT%s:%s", localTime.substring(0, 3), localTime.substring(3));
    Log.d(TAG, "timezone 1: " + finalTimezone);

    //Opt 2
    date = new SimpleDateFormat("z",Locale.getDefault());
    localTime = date.format(currentLocalTime);
    Log.d(TAG, "timezone 2: "+localTime);

My answer is specific to Laravel.

I had this message after creating a new connection in the database.php configuration file to a local Docker MySQL service and setting it as the default connection. I forgot that I was setting a different connection by overwriting it in the Model:

class Model extends \Illuminate\Database\Eloquent\Model
{
    protected $connection;

    public function __construct(array $attributes = [])
    {
        parent::__construct($attributes);
        $this->connection = 'some_other_connection';
    }
...

So even if my default connection in the database.php file was pointing to the right credentials, the model was still using the remote database connection configuration which I had removed from the local environment file.

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

VB.net, Desktop application. If you need lapsed time in milliseconds:

Dim starts As Integer = My.Computer.Clock.TickCount
Dim ends As Integer = My.Computer.Clock.TickCount
Dim lapsed As Integer = ends - starts

I have been writing a base class for all of my Pages and I came to the same issue. I had code like the following and It didn't work. By tracing, control passes from RedirectToLoginPage() statement to the next line without to be redirected.

if (_requiresAuthentication)
{
    if (!User.Identity.IsAuthenticated)
        FormsAuthentication.RedirectToLoginPage();

    // check authorization for restricted pages only
    if (_isRestrictedPage) AuthorizePageAndButtons();
}

I found out that there are two solutions. Either to modify FormsAuthentication.RedirectToLoginPage(); to be

if (!User.Identity.IsAuthenticated)
    Response.Redirect(FormsAuthentication.LoginUrl);

OR to modify the web.config by adding

<authorization>
  <deny users="?" />
</authorization>

In the second case, while tracing, control didn't reach the requested page. It has been redirected immediately to the login url before hitting the break point. Hence, The SignOut() method isn't the issue, the redirect method is the one.

I hope that may help someone

list = [1,1,1,0]
print(any(list)) # will return True because there is  1 or True exists

Without INDIRECT(): =CELL("width", OFFSET($A$1,ROW()-1,COLUMN()-1) )

You could compare the original value of the field and the changed value of the field and deduct the difference as the pasted value. This catches the pasted text correctly even if there is existing text in the field.

http://jsfiddle.net/6b7sK/

function text_diff(first, second) {
    var start = 0;
    while (start < first.length && first[start] == second[start]) {
        ++start;
    }
    var end = 0;
    while (first.length - end > start && first[first.length - end - 1] == second[second.length - end - 1]) {
        ++end;
    }
    end = second.length - end;
    return second.substr(start, end - start);
}
$('textarea').bind('paste', function () {
    var self = $(this);
    var orig = self.val();
    setTimeout(function () {
        var pasted = text_diff(orig, $(self).val());
        console.log(pasted);
    });
});

if you are using macOS, use sudo command

sudo npm install -g npx

You can do that using at. You can try out the following simple example:

const size_t N = 20;
std::vector<int> vec(N);
try {
    vec.at(N - 1) = 7;
} catch (std::out_of_range ex) {
    std::cout << ex.what() << std::endl;
}
assert(vec.at(N - 1) == 7);

Notice that method at returns an allocator_type::reference, which is that case is a int&. Using at is equivalent to assigning values like vec[i]=....

There is a difference between at and insert as it can be understood with the following example:

const size_t N = 8;
std::vector<int> vec(N);
for (size_t i = 0; i<5; i++){
    vec[i] = i + 1;
}

vec.insert(vec.begin()+2, 10);

If we now print out vec we will get:

1 2 10 3 4 5 0 0 0

If, instead, we did vec.at(2) = 10, or vec[2]=10, we would get

1 2 10 4 5 0 0 0

If someone views on my answer, you maybe in this condition:

1. Trying to get a map screenshot in canvas using openlayers (version >= 3)
2. And viewed the example of exporting map
3. Using ol.source.XYZ to render map layer

Bingo!

Using ol.source.XYZ.crossOrigin = 'Anonymous' to solve your confuse. Or like following code:

     var baseLayer = new ol.layer.Tile({
         name: 'basic',
         source: new ol.source.XYZ({
             url: options.baseMap.basic,
             crossOrigin: "Anonymous"
         })
     });

Unfortunately, the most common use of <a href="#"> is by lazy programmers who want clickable non-hyperlink javascript-coded elements that behave like anchors, but they can't be arsed to add cursor: pointer; or :hover styles to a class for their non-hyperlink elements, and are additionally too lazy to set href to javascript:void(0);.

The problem with this is that one <a href="#" onclick="some_function();"> or another inevitably ends up with a javascript error, and an anchor with an onclick javascript error always ends up following its href. Normally this ends up being an annoying jump to the top of the page, but in the case of sites using <base>, <a href="#"> is handled as <a href="[base href]/#">, resulting in an unexpected navigation. If any logable errors are being generated, you won't see them in the latter case unless you enable persistent logs.

If an anchor element is used as a non-anchor it should have its href set to javascript:void(0); for the sake of graceful degradation.

I just wasted two days debugging a random unexpected page redirect that should have simply refreshed the page, and finally tracked it down to a function raising the click event of an <a href="#">. Replacing the # with javascript:void(0); fixed it.

The first thing I'm doing Monday is purging the project of all instances of <a href="#">.

Realize this is an old question, but with the newer version of JQuery you can now do the following:

$("option[val=ID]").prop("selected",true);

This accomplishes the same thing as Box9's selected answer in one line.

All radio buttons inside of a share container are in the same group by default. Means, if you check one of them - others will be unchecked. If you want to create independent groups of radio buttons, you must situate them into different containers such as Group Box, or control their Checked state through code behind.

If you just want a list:

ArrayList<Class> myList = new ArrayList<Class>();

If you want an arraylist of a certain length (in this case size 10):

List<Class> myList = new ArrayList<Class>(10);

If you want to program against the interfaces (better for abstractions reasons):

List<Class> myList = new ArrayList<Class>();

Programming against interfaces is considered better because it's more abstract. You can change your Arraylist with a different list implementation (like a LinkedList) and the rest of your application doesn't need any changes.

Actually if you need to test background fetch you need to enable one option in scheme:

Another way how you can test it:

I found way for Print Log in Retrofit

OkHttpClient okHttpClient = new OkHttpClient.Builder()
            .addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                    Request request = chain.request();
                    if (BuildConfig.DEBUG) {
                        Log.e(getClass().getName(), request.method() + " " + request.url());
                        Log.e(getClass().getName(), "" + request.header("Cookie"));
                        RequestBody rb = request.body();
                        Buffer buffer = new Buffer();
                        if (rb != null)
                            rb.writeTo(buffer);
                        LogUtils.LOGE(getClass().getName(), "Payload- " + buffer.readUtf8());
                    }
                    return chain.proceed(request);
                }
            })
            .readTimeout(60, TimeUnit.SECONDS)
            .connectTimeout(60, TimeUnit.SECONDS)
            .build();

            iServices = new Retrofit.Builder()
                    .baseUrl("Your Base URL")
                    .client(okHttpClient)
                    .addConverterFactory(GsonConverterFactory.create())

Works for me.

You can try this

var scroll=$('#scroll');
scroll.animate({scrollTop: scroll.prop("scrollHeight")});

This CSS also shows a fixed height HTML table. It sets the height of the HTML tbody to 400 pixels and the HTML tbody scrolls when the it is larger, retaining the HTML thead as a non-scrolling element.

In addition, each th cell in the heading and each td cell the body should be styled for the desired fixed width.

#the-table {
  display: block;
  background: white; /* optional */
}

#the-table thead {
  text-align: left; /* optional */
}

#the-table tbody {
  display: block;
  max-height: 400px;
  overflow-y: scroll;
}

Sounds like you're looking to simulate the IE6 box model. You could use the CSS 3 property box-sizing: border-box to achieve this. This is supported by IE8, but for Firefox you would need to use -moz-box-sizing and for Safari/Chrome, use -webkit-box-sizing.

IE6 already computes the height wrong, so you're good in that browser, but I'm not sure about IE7, I think it will compute the height the same in quirks mode.

You can also wrap the output of a cmdlet (or pipeline) in @() to ensure that what you get back is an array rather than a single item.

For instance, dir usually returns a list, but depending on the options, it might return a single object. If you are planning on iterating through the results with a foreach-object, you need to make sure you get a list back. Here's a contrived example:

$results = @( dir c:\autoexec.bat)

One more thing... an empty array (like to initialize a variable) is denoted @().

The top answer doesn't work for PHP7, because it has wrong encoding, but I could figure the right encoding out with the other answers. This code also sends authentication cookies, which you probably want when dealing with e.g. PHP forums:

julia = function(juliacode) {
    fetch('julia.php', {
        method: "POST",
        credentials: "include", // send cookies
        headers: {
            'Accept': 'application/json, text/plain, */*',
            //'Content-Type': 'application/json'
            "Content-Type": "application/x-www-form-urlencoded; charset=UTF-8" // otherwise $_POST is empty
        },
        body: "juliacode=" + encodeURIComponent(juliacode)
    })
    .then(function(response) {
        return response.json(); // .text();
    })
    .then(function(myJson) {
        console.log(myJson);
    });
}

Just as a heads up, the '=' operator will pad strings with spaces in Transact-SQL. So 'abc' = 'abc ' will return true; 'abc' LIKE 'abc ' will return false. In most cases '=' will be correct, but in a recent case of mine it was not.

So while '=' is faster, LIKE might more explicitly state your intentions.

no need to do a replacement. the regex will give you what u wanted directly:

"(?<=_)[^_]*\.jpg"

tested with grep:

 echo "3.04_somename.jpg"|grep -oP "(?<=_)[^_]*\.jpg"

This is Mysql DB connection

from flask import Flask, render_template, request
from flask_mysqldb import MySQL

app = Flask(__name__)


app.config['MYSQL_HOST'] = 'localhost'
app.config['MYSQL_USER'] = 'root'
app.config['MYSQL_PASSWORD'] = 'root'
app.config['MYSQL_DB'] = 'MyDB'

mysql = MySQL(app)


@app.route('/', methods=['GET', 'POST']) 
def index():
    if request.method == "POST":
        details = request.form
        cur = mysql.connection.cursor()
        cur.execute ("_Your query_")
        mysql.connection.commit()
        cur.close()
        return 'success'
    return render_template('index.html')


if __name__ == '__main__':
    app.run()

Try adding this to your source:

debugger;

It works in most, if not all browsers. Just place it somewhere in your code, and it will act like a breakpoint.

You can use $.isEmptyObject(json)

https://api.jquery.com/jQuery.isEmptyObject

If you want to implement autocomplete functionality, then Completion Suggester is the most neat solution. The next blog post contains a very clear description how this works.

In two words, it's an in-memory data structure called an FST which contains valid suggestions and is optimised for fast retrieval and memory usage. Essentially, it is just a graph. For instance, and FST containing the words hotel, marriot, mercure, munchen and munich would look like this:

jsonIssues = [...jsonIssues,{ID:'3',Name:'name 3',Notes:'NOTES 3'}]

You cannot dereference a pointer without specifying its type because different data types will have different sizes in memory i.e. an int being 4 bytes, a char being 1 byte.

There is an alternative way of just killing the daemon process by calling

kill -TERM PID

where PID is the value stored in the file mysqld.pid or the mysqld process id which can be obtained by issuing the command ps -a | grep mysqld.

When the stored procedure returns a lot of columns and you do not want to manually "create" a temporary table to hold the result, I've found the easiest way is to go into the stored procedure and add an "into" clause on the last select statement and add 1=0 to the where clause.

Run the stored procedure once and go back and remove the SQL code you just added. Now, you'll have an empty table matching the stored procedure's result. You could either "script table as create" for a temporary table or simply insert directly into that table.

Consider the outcome of the tool 'stat':

  File: `infolog.txt'
  Size: 694         Blocks: 8          IO Block: 4096   regular file
Device: 801h/2049d  Inode: 11635578    Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1000/     fdr)   Gid: ( 1000/     fdr)
Access: 2009-01-01 22:04:15.000000000 -0800
Modify: 2009-01-01 22:05:05.000000000 -0800
Change: 2009-01-01 22:05:05.000000000 -0800

You can see here the three dates for Access/modify/change. There is no created date. You can only really be sure when the file contents were modified (the "modify" field) or its inode changed (the "change" field).

Examples of when both fields get updated:

"Modify" will be updated if someone concatenated extra information to the end of the file.

"Change" will be updated if someone changed permissions via chmod.

http://us2.php.net/manual/en/function.array-multisort.php see third example:

<?php

$data[] = array('volume' => 67, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 1);
$data[] = array('volume' => 85, 'edition' => 6);
$data[] = array('volume' => 98, 'edition' => 2);
$data[] = array('volume' => 86, 'edition' => 6);
$data[] = array('volume' => 67, 'edition' => 7);

foreach ($data as $key => $row) {
    $volume[$key]  = $row['volume'];
    $edition[$key] = $row['edition'];
}

array_multisort($volume, SORT_DESC, $edition, SORT_ASC, $data);

?>

fyi, using a unix (seconds from 1970) or mysql timestamp (YmdHis - 20100526014500) would be be easier for the parser but i think in your case it makes no difference.

Edit

Following solution could have problems with clustered indexes involved as mentioned here. Thanks to Martin for pointing this out.

The answer is kept to educate those (like me) who don't know all side-effects or ins and outs of SQL Server.

Expanding on the answer gaven by Quassnoi in your link, following works

DECLARE @Test TABLE (Number INTEGER, AText VARCHAR(2), ID INTEGER)
DECLARE @Number INT

INSERT INTO @Test VALUES (1, 'A', 1)
INSERT INTO @Test VALUES (2, 'B', 2)
INSERT INTO @Test VALUES (1, 'E', 5)
INSERT INTO @Test VALUES (3, 'C', 3)
INSERT INTO @Test VALUES (2, 'D', 4)

SET @Number = 0

;WITH q AS (
    SELECT  TOP 1000000 *
    FROM    @Test
    ORDER BY
            ID
)            
UPDATE  q
SET     @Number = Number = @Number + 1

Note: It also works for #if / #elif / #endif matching. The caret must be on the #.

For ScrollView, you could use fillViewport=true and make layout_height="match_parent" as below and put recycler view inside:

<ScrollView
    android:fillViewport="true"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@+id/llOptions">
          <android.support.v7.widget.RecyclerView
            android:id="@+id/rvList"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />
</ScrollView>

No further height adjustment needed through code.

I totally agree with the above answer. The only thing is that for me the solution was set the code in viewDidAppear

viewDidAppear 
{
    [self.collectionView scrollToItemAtIndexPath:indexPath atScrollPosition:UICollectionViewScrollPositionCenteredVertically animated:YES];
}

When I used the viewWillAppear the scrolling didn't work.

I really love this excerpt from 10 Things I hate about git (it gives a short explanation for rebase in its second example):

3. Crappy documentation

The man pages are one almighty “f*** you”¹. They describe the commands from the perspective of a computer scientist, not a user. Case in point:

git-push – Update remote refs along with associated objects

Here’s a description for humans:

git-push – Upload changes from your local repository into a remote repository

Update, another example: (thanks cgd)

git-rebase – Forward-port local commits to the updated upstream head

Translation:

git-rebase – Sequentially regenerate a series of commits so they can be 
             applied directly to the head node

And then we have

git-merge - Join two or more development histories together

which is a good description.

^{1. uncensored in the original}

Addition to Mark Byers answer :

Sometimes you also want to insert Hardcoded details else there may be Unique constraint fail etc. So use following in such situation where you override some values of the columns.

INSERT INTO matrimony_domain_details (domain, type, logo_path)
SELECT 'www.example.com', type, logo_path
FROM matrimony_domain_details
WHERE id = 367

Here domain value is added by me me in Hardcoded way to get rid from Unique constraint.

You need to declare @font-face like this in your stylesheet

@font-face {
  font-family: 'Awesome-Font';
  font-style: normal;
  font-weight: 400;
  src: local('Awesome-Font'), local('Awesome-Font-Regular'), url(path/Awesome-Font.woff) format('woff');
}

Now if you want to apply this font to a paragraph simply use it like this..

p {
font-family: 'Awesome-Font', Arial;
}

More Reference

C#:

String[] listOfPipes = System.IO.Directory.GetFiles(@"\\.\pipe\");

dict(rank = int(lst[0]),
                grade = str(lst[1]),
                channel=str(lst[2])),
                videos = float(lst[3].replace(",", " ")),
                subscribers = float(lst[4].replace(",", "")),
                views = float(lst[5].replace(",", "")))

RelativeSource vs. ElementName

These two approaches can achieve the same result,

RelativeSource

Binding="{Binding Path=DataContext.MyBindingProperty, 
          RelativeSource={RelativeSource AncestorType={x:Type Window}}}"

This method looks for a control of a type Window (in this example) in the visual tree and when it finds it you basically can access it's DataContext using the Path=DataContext..... The Pros about this method is that you don't need to be tied to a name and it's kind of dynamic, however, changes made to your visual tree can affect this method and possibly break it.

ElementName

Binding="{Binding Path=DataContext.MyBindingProperty, ElementName=MyMainWindow}

This method referes to a solid static Name so as long as your scope can see it, you're fine.You should be sticking to your naming convention not to break this method of course.The approach is qute simple and all you need is to specify a Name="..." for your Window/UserControl.

Although all three types (RelativeSource, Source, ElementName) are capable of doing the same thing, but according to the following MSDN article, each one better be used in their own area of specialty.

How to: Specify the Binding Source

import numpy as np
x = np.array([[1,2,3], [4,5,6]])
y = np.array([[-1, 2, 0], [-2, 5, 1]])

x*y
Out: 
array([[-1,  4,  0],
       [-8, 25,  6]])

%timeit x*y
1000000 loops, best of 3: 421 ns per loop

np.multiply(x,y)
Out: 
array([[-1,  4,  0],
       [-8, 25,  6]])

%timeit np.multiply(x, y)
1000000 loops, best of 3: 457 ns per loop

Both np.multiply and * would yield element wise multiplication known as the Hadamard Product

%timeit is ipython magic

Some posts have showed how to display the command's progress. In order to calculate it, you'll need to see how much you've progressed. On BSD systems some commands, such as dd(1), accept a SIGINFO signal, and will report their progress. On Linux systems some commands will respond similarly to SIGUSR1. If this facility is available, you can pipe your input through dd to monitor the number of bytes processed.

Alternatively, you can use lsof to obtain the offset of the file's read pointer, and thereby calculate the progress. I've written a command, named pmonitor, that displays the progress of processing a specified process or file. With it you can do things, such as the following.

$ pmonitor -c gzip
/home/dds/data/mysql-2015-04-01.sql.gz 58.06%

Use a font-awesome icon as the default icon of your navbar.

<span class="navbar-toggler-icon">   
    <i class="fas fa-bars" style="color:#fff; font-size:28px;"></i>
</span>

Or try this on old font-awesome versions:

<span class="navbar-toggler-icon">   
    <i class="fa fa-navicon" style="color:#fff; font-size:28px;"></i>
</span>

Instead of

Player[PlayerCount] thePlayers;

you want

Player[] thePlayers = new Player[PlayerCount];

and

for(int i = 0; i < PlayerCount ; i++)
{
    thePlayers[i] = new Player(i);
}
return thePlayers;

should return the array initialized with Player instances.

Do check out this table on wikipedia on naming conventions for java that is widely used.

The two <path>s are what you need to change to the directories in question.

I used string to concatenate new object to an existing object.

private static void concatJSON() throws IOException, InterruptedException {

    JSONParser parser = new JSONParser();
    Object obj = parser.parse(new FileReader(new File(Main.class.getResource("/file/user.json").toURI())));


    JSONObject jsonObj = (JSONObject) obj; //usernameJsonObj

    String [] values = {"0.9" , Date.from(Calendar.getInstance().toInstant()).toLocaleString()},
            innermost = {"Accomplished", "LatestDate"}, 
            inner = {"Lesson1", "Lesson2", "Lesson3", "Lesson4"};
    String in = "Jayvee Villa";

    JSONObject jo1 = new JSONObject();
    for (int i = 0; i < innermost.length; i++)
        jo1.put(innermost[i], values[i]);

    JSONObject jo2 = new JSONObject();
    for (int i = 0; i < inner.length; i++)
        jo2.put(inner[i], jo1);

    JSONObject jo3 = new JSONObject();
    jo3.put(in, jo2);

    String merger = jsonObj.toString().substring(0, jsonObj.toString().length()-1) + "," +jo3.toString().substring(1);

    System.out.println(merger);
    FileWriter pr = new FileWriter(file);
    pr.write(merger);
    pr.flush();
    pr.close();
}

To expand Konamiman's solution (including all relevant null checks), this is what I've been doing:

if (node.Attributes != null)
{
   var nameAttribute = node.Attributes["Name"];
   if (nameAttribute != null) 
      return nameAttribute.Value;

   throw new InvalidOperationException("Node 'Name' not found.");
}

Assuming you have the menuStrip object and the menu is only one level deep, use:

ToolStripMenuItem item = menuStrip.Items
    .OfType<ToolStripMenuItem>()
    .SelectMany(it => it.DropDownItems.OfType<ToolStripMenuItem>())
    .SingleOrDefault(n => n.Name == "MyMenu");

For deeper menu levels add more SelectMany operators in the statement.

if you want to search all menu items in the strip then use

ToolStripMenuItem item = menuStrip.Items
    .Find("MyMenu",true)
    .OfType<ToolStripMenuItem>()
    .Single();

However, make sure each menu has a different name to avoid exception thrown by key duplicates.

To avoid exceptions you could use FirstOrDefault instead of SingleOrDefault / Single, or just return a sequence if you might have Name duplicates.

to close fancybox by funciton its necessary to make setTimtout to the function that will close the fancybox Fancybox needs some time to acept the close function If you call the function directly will not work

function close_fancybox(){
$.fancybox.close();
                     }
setTimeout(close_fancybox, 50);

To get each sum in a separate column:

Select SUM(IF(CPaymentType='Check', CAmount, 0)) as PaymentAmountCheck,
       SUM(IF(CPaymentType='Cash', CAmount, 0)) as PaymentAmountCash
from TableOrderPayment
where CPaymentType IN ('Check','Cash') 
and CDate<=SYSDATETIME() 
and CStatus='Active';

If you do not have "-mmin" in your version of "find", then "-mtime -0.041667" gets pretty close to "within the last hour", so in your case, use:

-mtime +(X * 0.041667)

so, if X means 6 hours, then:

find . -mtime +0.25 -ls

works because 24 hours * 0.25 = 6 hours

This will prevent multiple context tags to be created upon each request

1) Stop the server
2) Clean Tomcat's work directory

A more elegant solution

echo "Enter the file name"
read x
if [ -f $x ]
then
    echo "This is a regular file"
else
    echo "This is a directory"
fi

Put empty value if the value does not exist or null.

value={ this.state.value || "" }

The error you're seeing is that CMake cannot find a FindOpenCV.cmake file, because cmake doesn't include one out of the box. Therefore you need to find one and put it where cmake can find it:

You can find a good start here. If you're feeling adventurous you can also write your own.

Then add it somewhere in your project and adjust CMAKE_MODULE_PATH so that cmake can find it.

e.g., if you have

CMakeLists.txt
cmake-modules/FindOpenCV.cmake

Then you should do a

set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} ${CMAKE_CURRENT_SOURCE_DIR}/cmake-modules)

In your CMakeLists.txt file before you do a find_package(OpenCV)

Tickcount is good, however i suggest running it 100 or 1000 times, and calculating an average. Not only makes it more measurable - in case of really fast/short functions, but helps dealing with some one-off effects caused by the overhead.

You can start by reading the data structure alignment wikipedia article to get a better understanding of data alignment.

From the wikipedia article:

Data alignment means putting the data at a memory offset equal to some multiple of the word size, which increases the system's performance due to the way the CPU handles memory. To align the data, it may be necessary to insert some meaningless bytes between the end of the last data structure and the start of the next, which is data structure padding.

From 6.54.8 Structure-Packing Pragmas of the GCC documentation:

For compatibility with Microsoft Windows compilers, GCC supports a set of #pragma directives which change the maximum alignment of members of structures (other than zero-width bitfields), unions, and classes subsequently defined. The n value below always is required to be a small power of two and specifies the new alignment in bytes.

1. #pragma pack(n) simply sets the new alignment.
2. #pragma pack() sets the alignment to the one that was in effect when compilation started (see also command line option -fpack-struct[=] see Code Gen Options).
3. #pragma pack(push[,n]) pushes the current alignment setting on an internal stack and then optionally sets the new alignment.
4. #pragma pack(pop) restores the alignment setting to the one saved at the top of the internal stack (and removes that stack entry). Note that #pragma pack([n]) does not influence this internal stack; thus it is possible to have #pragma pack(push) followed by multiple #pragma pack(n) instances and finalized by a single #pragma pack(pop).

Some targets, e.g. i386 and powerpc, support the ms_struct #pragma which lays out a structure as the documented __attribute__ ((ms_struct)).

1. #pragma ms_struct on turns on the layout for structures declared.
2. #pragma ms_struct off turns off the layout for structures declared.
3. #pragma ms_struct reset goes back to the default layout.

You can't, you'll have to do something like

<script type="text/javascript">
   var php_var = "<?php echo $php_var; ?>";
</script>

You can also load it with AJAX

rhino is right, the snippet lacks of a type for the sake of brevity.

Also, note that if $php_var has quotes, it will break your script. You shall use addslashes, htmlentities or a custom function.

Beyond removing .m2/repository, remove application from server, run server (without applications), stop it and add application again. Now it is supposed to work. For some reason just cleaning up server folders from interface doesn't have the same effect.

Using UTC

ISO 8601 (MSDN datetime formats)

Console.WriteLine(DateTime.UtcNow.ToString("s") + "Z");

2009-11-13T10:39:35Z

The Z is there because

If the time is in UTC, add a 'Z' directly after the time without a space. 'Z' is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".

If you want to include an offset

int hours = TimeZoneInfo.Local.BaseUtcOffset.Hours;
string offset = string.Format("{0}{1}",((hours >0)? "+" :""),hours.ToString("00"));
string isoformat = DateTime.Now.ToString("s") + offset;
Console.WriteLine(isoformat);

Two things to note: + or - is needed after the time but obviously + doesn't show on positive numbers. According to wikipedia the offset can be in +hh format or +hh:mm. I've kept to just hours.

As far as I know, RFC1123 (HTTP date, the "u" formatter) isn't meant to give time zone offsets. All times are intended to be GMT/UTC.

WAMP server generally provide addond for different php/mysql versions. However you mentioned you have downloaded latest wamp server. As of now, latest Wamp server v2.5 provide PHP version 5.5.12

So you need to upgrade it manually as follow:

1. Download binaries on php.net
2. Extract all files in a new folder : C:/wamp/bin/php/php5.5.27/
3. Copy the wampserver.conf from another php folder (like php/php5.5.12/) to the new folder
4. Rename php.ini-development file to phpForApache.ini
5. Done ! Restart WampServer (>Right Mouseclick on trayicon >Exit)

Although not asked, I'd recommend to vagrant/puppet or docker for local development. Check puphpet.com for details. It has slight learning curve but it will give you much better control of different versions of every tool.

Comma separate the values:

UPDATE settings SET postsPerPage = $postsPerPage, style = $style WHERE id = '1'"

Use the display property

a{
    display: block;
}

This will make the link to display in new line

If you want to remove list styling, use

li{
    list-style: none;
}

Try with enabling the sub-thread as daemon-thread.

For Instance:

Recommended:

from threading import Thread

t = Thread(target=<your-method>)
t.daemon = True  # This thread dies when main thread (only non-daemon thread) exits.
t.start()

Inline:

t = Thread(target=<your-method>, daemon=True).start()

Old API:

t.setDaemon(True)
t.start()

When your main thread terminates ("i.e. when I press Ctrl+C"), other threads will also be killed by the instructions above.

You need to be using a Maven plugin for Eclipse in order to do this properly. The m2e plugin is built into the latest version of Eclipse, and does a decent if not perfect job of integrating Maven into the IDE. You will want to create your project as a 'Maven Project'. Alternatively you can import an existing Maven POM into your workspace to automatically create projects. Once you have your Maven project in the IDE, simply open up the POM and add your dependency to it.

Now, if you do not have a Maven plugin for Eclipse, you will need to get the jar(s) for the dependency in question and manually add them as classpath references to your project. This could get unpleasant as you will need not just the top level JAR, but all its dependencies as well.

Basically, I recommend you get a decent Maven plugin for Eclipse and let it handle the dependency management for you.

You can also use ngrok: https://ngrok.com/. I use it all the time to have a public server running on my localhost. Hope this helps.

Another options which even provides your own custom domain for free are serveo.net and https://localtunnel.github.io/www/

grab the second child:

$(t).children().eq(1);

or, grab the second child <td>:

$(t).children('td').eq(1);

See documentation for children and eq.

You can do it right in your XML file:

android:onClick="@drawable/ic_action_search"

Environment variables are accessed through os.environ

import os
print(os.environ['HOME'])

Or you can see a list of all the environment variables using:

os.environ

As sometimes you might need to see a complete list!

# using get will return `None` if a key is not present rather than raise a `KeyError`
print(os.environ.get('KEY_THAT_MIGHT_EXIST'))

# os.getenv is equivalent, and can also give a default value instead of `None`
print(os.getenv('KEY_THAT_MIGHT_EXIST', default_value))

Python default installation on Windows is C:\Python. If you want to find out while running python you can do:

import sys
print(sys.prefix)

For me, this helped: 1. Configuration properties/General/Platform Toolset = Windows XP (V110_xp) 2. C/C++ Preprocessor definitions, add "WIN32" 3. Linker/System/Minimum required version = 5.01

It may means that you forgot include a header file that define this struct/union. For example:

foo.h file:

typedef union
{
    struct
    {
        uint8_t FIFO_BYTES_AVAILABLE    : 4;
        uint8_t STATE                   : 3;
        uint8_t CHIP_RDY                : 1;
    };
    uint8_t status;
} RF_CHIP_STATUS_t;

RF_CHIP_STATUS_t getStatus();

main.c file:

.
.
.
if (getStatus().CHIP_RDY) /* This will generate the error, you must add the  #include "foo.h" */
.
.
.

Edit: In case anyone else is having this problem, I believe the solution for OP was that he had not imported popper.js.

Check that jQuery and all the relevant Bootstrap components are there. Also check the console and make sure there are no errors.

If you're using SwiftUI

If you're updating from a previous version of Xcode 11, there are some changes to the SceneDelegate willConnectTo session: options connectionOptions initialization:

The main window is now initialized using UIWindow(windowScene: windowScene), where it use to be UIWindow(frame: UIScreen.main.bounds)

On previous version:

    let window = UIWindow(frame: UIScreen.main.bounds)
    window.rootViewController = UIHostingController(rootView: ContentView())
    self.window = window
    window.makeKeyAndVisible()

In new version:

    if let windowScene = scene as? UIWindowScene {
        let window = UIWindow(windowScene: windowScene)
        window.rootViewController = UIHostingController(rootView: ContentView())
        self.window = window
        window.makeKeyAndVisible()
    }

Combine Dynamic SQL with OpenQuery. (This goes to a Teradata server)

DECLARE 
    @dayOfWk    TINYINT = DATEPART(DW, GETDATE()),
    @qSQL       NVARCHAR(MAX) = '';

SET @qSQL = '
SELECT
    *
FROM
    OPENQUERY(TERASERVER,''
        SELECT DISTINCT
            CASE
                WHEN ' + CAST(@dayOfWk AS NCHAR(1)) + ' = 2
                THEN ''''Monday''''
                ELSE ''''Not Monday''''
            END
        '');';

EXEC sp_executesql @qSQL;

x = math.ceil(x * 100.0) / 100.0

In Python 2.7 this might have worked fine:

>>> a = b = c = range(20)
>>> zip(a, b, c)

But in Python 3.4 it should be (otherwise, the result will be something like <zip object at 0x00000256124E7DC8>):

>>> a = b = c = range(20)
>>> list(zip(a, b, c))

I found I had the same error. I was compiling a code with both lapack and blas. When I switched the order that the two libraries were called the error went away.

"LAPACK_LIB = -llapack -lblas" worked where "LAPACK_LIB = -lblas -llapack" gave the error described above.

I think you want preg_split:

$input = "A  B C   D";
$words = preg_split('/\s+/', $input);
var_dump($words);

As matt burns says in his answer, you may need to enable CORS on the server where the problem images are hosted.

If the server is Apache, this can be done by adding the following snippet (from here) to either your VirtualHost config or an .htaccess file:

<IfModule mod_setenvif.c>
    <IfModule mod_headers.c>
        <FilesMatch "\.(cur|gif|ico|jpe?g|png|svgz?|webp)$">
            SetEnvIf Origin ":" IS_CORS
            Header set Access-Control-Allow-Origin "*" env=IS_CORS
        </FilesMatch>
    </IfModule>
</IfModule>

...if adding it to a VirtualHost, you'll probably need to reload Apache's config too (eg. sudo service apache2 reload if Apache's running on a Linux server)

It means that if x is set, the value for z will be x, otherwise if y is set then its value will be set as the z's value.

it's the same as

if(x)
  z = x;
else
  z = y;

It's possible because logical operators in JavaScript doesn't return boolean values but the value of the last element needed to complete the operation (in an OR sentence it would be the first non-false value, in an AND sentence it would be the last one). If the operation fails, then false is returned.

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

Try this, its working in FF

body,
input,
select,
button {
 font-family: Arial,Helvetica,sans-serif;
 font-size: 14px;
}

Try to follow the advice you see on the screen, and first reset your master's HEAD to the commit it expects.

git update-ref refs/heads/master b918ac16a33881ce00799bea63d9c23bf7022d67

Then, abort the rebase again.

For sin specifically, using Taylor expansion would give you:

sin(x) := x - x^3/3! + x^5/5! - x^7/7! + ... (1)

you would keep adding terms until either the difference between them is lower than an accepted tolerance level or just for a finite amount of steps (faster, but less precise). An example would be something like:

float sin(float x)
{
  float res=0, pow=x, fact=1;
  for(int i=0; i<5; ++i)
  {
    res+=pow/fact;
    pow*=-1*x*x;
    fact*=(2*(i+1))*(2*(i+1)+1);
  }

  return res;
}

Note: (1) works because of the aproximation sin(x)=x for small angles. For bigger angles you need to calculate more and more terms to get acceptable results. You can use a while argument and continue for a certain accuracy:

double sin (double x){
    int i = 1;
    double cur = x;
    double acc = 1;
    double fact= 1;
    double pow = x;
    while (fabs(acc) > .00000001 &&   i < 100){
        fact *= ((2*i)*(2*i+1));
        pow *= -1 * x*x; 
        acc =  pow / fact;
        cur += acc;
        i++;
    }
    return cur;

}

It's caused by the DOS/Windows line-ending characters. Like Andy Whitfield said, the Unix command dos2unix will help fix the problem. If you want more information, you can read the man pages for that command.

Recently I learned of the following syntax:

DELETE (SELECT *
        FROM productfilters pf
        INNER JOIN product pr
            ON pf.productid = pr.id
        WHERE pf.id >= 200
            AND pr.NAME = 'MARK')

I think it looks much cleaner then other proposed code.

You don't need to use array_push() function, you can assign new value with new key directly to the array like..

$array = array("color1"=>"red", "color2"=>"blue");
$array['color3']='green';
print_r($array);


Output:

   Array(
     [color1] => red
     [color2] => blue
     [color3] => green
   )

My guess is you are using a Set<Role> in the User class annotated with @OneToMany. Which means one User has many Roles. But on the same field you use the @Column annotation which makes no sense. One-to-many relationships are managed using a separate join table or a join column on the many side, which in this case would be the Role class. Using @JoinColumn instead of @Column would probably fix the issue, but it seems semantically wrong. I guess the relationship between role and user should be many-to-many.

If your administrator changed your password, and Windows 10 still stores your old password you will not be asked for a new password. Windows 10 will use the stored old password, and authentication will fail.

You can delete your old password by

1. Click Start > Control Panel > User Accounts > Manage your credentials
2. Windows credentials
3. Modify or delete the stored password

If you delete a password, when you try to use SVN, you will be asked for the new password.

Testing ErrorLevel works for console applications, but as hinted at by dmihailescu, this won't work if you're trying to run a windowed application (e.g. Win32-based) from a command prompt. A windowed application will run in the background, and control will return immediately to the command prompt (most likely with an ErrorLevel of zero to indicate that the process was created successfully). When a windowed application eventually exits, its exit status is lost.

Instead of using the console-based C++ launcher mentioned elsewhere, though, a simpler alternative is to start a windowed application using the command prompt's START /WAIT command. This will start the windowed application, wait for it to exit, and then return control to the command prompt with the exit status of the process set in ErrorLevel.

start /wait something.exe
echo %errorlevel%

This example is using Lists: When clicking in some li it turn red

html:

<div id="app">
  <ul>
    <li @click="activate(li.id)" :class="{ active : active_el == li.id }" v-for="li in lista">{{li.texto}}</li>   
  </ul>
</div>

JS:

var app = new Vue({
  el:"#app",
  data:{
    lista:[{"id":"1","texto":"line 1"},{"id":"2","texto":"line 2"},{"id":"3","texto":"line 3"},{"id":"4","texto":"line 4"},{"id":"5","texto":"line 5"}],
    active_el:0
  },
  methods:{
    activate:function(el){
        this.active_el = el;
    }
  }
});

[INFO] --- pitest-maven:1.1.3:mutationCoverage (default-cli) @ module-selenium --- [INFO] Skipping project

If you use numpy,

if np.zeros(3)==None: pass

will give you error when numpy does elementwise comparison

If you are using NodeJs for your server side, just add these to your route and you will be Ok

     res.header("Access-Control-Allow-Origin", "*");
     res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");

Your route will then look somehow like this

    router.post('/odin', function(req, res, next) {
      res.header("Access-Control-Allow-Origin", "*");
      res.header("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");


    return res.json({Name: req.body.name, Phone: req.body.phone});
});

Client side for Ajax call

 var sendingData = {
   name: "Odinfono Emmanuel",
   phone: "1234567890"
}

<script>
  $(document).ready(function(){

    $.ajax({
        url: 'http://127.0.0.1:3000/odin',            
        method: 'POST',
        type: 'json',
        data: sendingData,
        success: function (response) {
            console.log(response);
        },
        error: function (error) {
            console.log(error);
        }
        });
    });
</script>

You should have something like this in your browser console as response

{ name: "Odinfono Emmanuel", phone: "1234567890"}

Enjoy coding....

For a quick n' dirty self-signed cert, you can also use flask run --cert adhoc or set the FLASK_RUN_CERT env var.

$ export FLASK_APP="app.py"
$ export FLASK_ENV=development
$ export FLASK_RUN_CERT=adhoc

$ flask run
 * Serving Flask app "app.py" (lazy loading)
 * Environment: development
 * Debug mode: on
 * Running on https://127.0.0.1:5000/ (Press CTRL+C to quit)
 * Restarting with stat
 * Debugger is active!
 * Debugger PIN: 329-665-000

The adhoc option isn't well documented (for good reason, never do this in production), but it's mentioned in the cli.py source code.

There's a thorough explanation of this by Miguel Grinberg at Running Your Flask Application Over HTTPS.

I'm guessing - are you trying to create Dialog using.

 getApplicationContext()
 mContext which is passed by activity.

if You displaying dialog non activity class then you have to pass activity as a parameter.

Activity activity=YourActivity.this;

Now it will be work great.

If you find any trouble then let me know.

The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).

In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character

So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).

And you can mix “combining above” and “combining below” marks.

The sample text in the question starts with:

• LATIN CAPITAL LETTER H - H
• COMBINING LATIN SMALL LETTER T - ͭ
• COMBINING GREEK KORONIS - ̓
• COMBINING COMMA ABOVE - ̓
• COMBINING DOT ABOVE - ̇

Use ResXResourceReader Class

ResXResourceReader rsxr = new ResXResourceReader("your resource file path");

// Iterate through the resources and display the contents to the console.
foreach (DictionaryEntry d in rsxr)
{
    Console.WriteLine(d.Key.ToString() + ":\t" + d.Value.ToString());
}

This question already has a great answer, but I ran into the same error, in a different scenario: displaying a List in an EditorTemplate.

I have a model like this:

public class Foo
{
    public string FooName { get; set; }
    public List<Bar> Bars { get; set; }
}

public class Bar
{
    public string BarName { get; set; }
}

And this is my main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
@Html.EditorFor(m => m.Bars)

And this is my Bar EditorTemplate (Bar.cshtml)

@model List<Bar>

<div class="some-style">
    @foreach (var item in Model)
    {
        <label>@item.BarName</label>
    }
</div>

And I got this error:

The model item passed into the dictionary is of type 'Bar', but this dictionary requires a model item of type 'System.Collections.Generic.List`1[Bar]

The reason for this error is that EditorFor already iterates the List for you, so if you pass a collection to it, it would display the editor template once for each item in the collection.

This is how I fixed this problem:

Brought the styles outside of the editor template, and into the main view:

@model Foo

@Html.TextBoxFor(m => m.Name, new { @class = "form-control" })  
<div class="some-style">
    @Html.EditorFor(m => m.Bars)
</div>

And changed the EditorTemplate (Bar.cshtml) to this:

@model Bar

<label>@Model.BarName</label>

org.apache.commons.lang3.StringEscapeUtils from commons-lang3 is marked deprecated now. You can use org.apache.commons.text.StringEscapeUtils#unescapeJava(String) instead. It requires an additional Maven dependency:

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-text</artifactId>
            <version>1.4</version>
        </dependency>

and seems to handle some more special cases, it e.g. unescapes:

• escaped backslashes, single and double quotes
• escaped octal and unicode values
• \\b, \\n, \\t, \\f, \\r

<FilesMatch "\.(js|css)$">
  ExpiresActive On
  ExpiresDefault A1

 (from p in context.ParentTable     
  join c in context.ChildTable 
    on p.ParentId equals c.ChildParentId into j1 
  from j2 in j1.DefaultIfEmpty() 
     select new { 
          ParentId = p.ParentId,
         ChildId = j2==null? 0 : 1 
      })
   .GroupBy(o=>o.ParentId) 
   .Select(o=>new { ParentId = o.key, Count = o.Sum(p=>p.ChildId) })

If the order doesn't matter, we can re-iterate backward with the same iterator using the hasPrevious() and previous() methods:

ListIterator<T> lit = myList.listIterator(); // create just one iterator

Initially the iterator sits at the beginning, we do forward iteration:

while (lit.hasNext()) process(lit.next()); // begin -> end

Then the iterator sits at the end, we can do backward iteration:

while (lit.hasPrevious()) process2(lit.previous()); // end -> begin

After a few days of struggle, this works for me, and I hope this also works for you.

add this to your CONFIG.XML, top of your code.

<access origin="*" />
<allow-navigation href="*" />

and this, under the platform android.

<edit-config file="app/src/main/AndroidManifest.xml" 
   mode="merge" target="/manifest/application" 
   xmlns:android="http://schemas.android.com/apk/res/android">
     <application android:usesCleartextTraffic="true" />
     <application android:networkSecurityConfig="@xml/network_security_config" />
 </edit-config>
 <resource-file src="resources/android/xml/network_security_config.xml" 
 target="app/src/main/res/xml/network_security_config.xml" />

add the follow code to this file "resources/android/xml/network_security_config.xml".

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <base-config cleartextTrafficPermitted="true">
        <trust-anchors>
            <certificates src="system" />
        </trust-anchors>
    </base-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">localhost</domain>
        <domain includeSubdomains="true">YOUR DOMAIN HERE/IP</domain>
    </domain-config>

I've not seen this solution presented yet; this is my preference for its simpler readability:

select dateadd(month,-1,format(getutcdate(),'yyyy-MM-01'))

I lived this problem in two days and suddenly I realized it that I am using this click method(for asp button) in a submit button(in html submit button) javascript method...

I mean ->

I have an html submit button and an asp button like these:

<input type="submit" value="Siparisi Gönder" onclick="SendEmail()" />_x000D_
<asp:Button ID="sendEmailButton" runat="server" Text="Gönder" OnClick="SendToEmail" Visible="True"></asp:Button>

SendToEmail() is a server side method in Default.aspx SendEmail() is a javascript method like this:

<script type="text/javascript" lang="javascript">_x000D_
   function SendEmail() {_x000D_
            document.getElementById('<%= sendEmailButton.UniqueID %>').click();_x000D_
            alert("Your message is sending...");_x000D_
        }_x000D_
</script>

And this "document.getElementById('<%= sendEmailButton.UniqueID %>').click();" method did not work in just Crome. It was working in IE and Firefox.

Then I tried and tried a lot of ways for executing "SendToEmail()" method in Crome.

Then suddenly I changed html submit button --> just html button like this and now it is working:

<input type="button" value="Siparisi Gönder" onclick="SendEmail()" />

Have a nice days...

Here is a noise-free version of the solution which is to use with_items:

- name: add lines
  lineinfile: 
    dest: fruits.txt
    line: '{{ item }}'
  with_items:
    - 'Orange'
    - 'Apple'
    - 'Banana' 

For each item, if the item exists in fruits.txt no action is taken.

If the item does not exist it will be appended to the end of the file.

Easy-peasy.

Use str.split([sep[, maxsplit]]) with no sep or sep=None:

From docs:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

Demo:

>>> myString.split()
['I', 'want', 'to', 'Remove', 'all', 'white', 'spaces,', 'new', 'lines', 'and', 'tabs']

Use str.join on the returned list to get this output:

>>> ' '.join(myString.split())
'I want to Remove all white spaces, new lines and tabs'

Think of the phrase in the square brackets as a WHERE clause in SQL.

So this query says, "select the "href" attribute (@) of an "a" tag that appears anywhere (//), but only where (the bracketed phrase) the textual contents of the "a" tag is equal to 'programming questions site'".

Just add an doctype declaration before the html tag

ex.: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/strict.dtd">

It is gonna work in JSP files as well. For further info: HTML Doctype Declaration

You can use simple way for genarate RSA . Use rsa library

pip install rsa 

Omitting the header above the divider produces a headerless table in at least Perl Text::MultiMarkdown and in FletcherPenney MultiMarkdown

|-------------|--------|
|**Name:**    |John Doe|
|**Position:**|CEO     |

See PHP Markdown feature request

Empty headers in PHP Parsedown produce tables with empty headers that are usually invisible (depending on your CSS) and so look like headerless tables.

|     |     |
|-----|-----|
|Foo  |37   |
|Bar  |101  |

In C++ you can use EscapeXML ATL API. This is the correct way of handling special chars ...

and how do I then make the warning go away?

You are probably going to have to reinstall or upgrade your NuGet packages to fix this.

number_list = [99.5,1.2,-0.3]

number_list.sort()

print number_list[0]

There is no "second property" -- when you say var obj = { ... }, the properties inside the braces are unordered. Even a 'for' loop walking through them might return them in different orders on different JavaScript implementations.

If you want send ANSI color to console, get this tiny package,

Thanks to the talk with Sarfraz we could figure out the solution.

The problem was that I was passing an HTML element instead of its value, which is actually what I wanted to do (in fact in my php code I need that value as a foreign key for querying my cities table and filter correct entries).

So, instead of:

var data = {
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex]
};

it should be:

var data = {
        'mode': 'filter_city',
        'id_A': e[e.selectedIndex].value
};

Note: check Jason Kulatunga's answer, it quotes JQuery doc to explain why passing an HTML element was causing troubles.

The top answers in this question may be misleading in some cases. Imagine that the file, whose absolute path you want to find, is in the $PATH variable:

# node is in $PATH variable
type -P node
# /home/user/.asdf/shims/node
cd /tmp
touch node
readlink -e node
# /tmp/node
readlink -m node
# /tmp/node
readlink -f node
# /tmp/node
echo "$(cd "$(dirname "node")"; pwd -P)/$(basename "node")"
# /tmp/node
realpath node
# /tmp/node
realpath -e node
# /tmp/node

# Now let's say that for some reason node does not exist in current directory
rm node
readlink -e node
# <nothing printed>
readlink -m node    
# /tmp/node         # Note: /tmp/node does not exist, but is printed
readlink -f node
# /tmp/node         # Note: /tmp/node does not exist, but is printed
echo "$(cd "$(dirname "node")"; pwd -P)/$(basename "node")"
# /tmp/node         # Note: /tmp/node does not exist, but is printed
realpath node
# /tmp/node         # Note: /tmp/node does not exist, but is printed
realpath -e node
# realpath: node: No such file or directory

Based on the above I can conclude that: realpath -e and readlink -e can be used for finding the absolute path of a file, that we expect to exist in current directory, without result being affected by the $PATH variable. The only difference is that realpath outputs to stderr, but both will return error code if file is not found:

cd /tmp
rm node
realpath -e node ; echo $?
# realpath: node: No such file or directory
# 1
readlink -e node ; echo $?
# 1

Now in case you want the absolute path a of a file that exists in $PATH, the following command would be suitable, independently on whether a file with same name exists in current dir.

type -P example.txt
# /path/to/example.txt

# Or if you want to follow links
readlink -e $(type -P example.txt)
# /originalpath/to/example.txt

# If the file you are looking for is an executable (and wrap again through `readlink -e` for following links )
which executablefile
# /opt/bin/executablefile

And a, fallback to $PATH if missing, example:

cd /tmp
touch node
echo $(readlink -e node || type -P node)
# /tmp/node
rm node
echo $(readlink -e node || type -P node)
# /home/user/.asdf/shims/node

I have recently ran across similar situation. To debug in any VS IDE version, open exceptions from Debug (Ctrl + D, E) - check all checkboxes against the column "Thrown", and run the application in debug mode. I have realized that one of the tables was not imported properly in the new database, so internal Sql Exception was killing the connection, thus results into this error.

Gist of the story is, If Previously working code returns this error on a new database, this could be database schema missing issue, realize by above debugging tip,

Hope It Helps, HydTechie

Try this

ifnull(X,Y)  

e.g

select ifnull(InfoDetail,'') InfoDetail; -- this will replace null with ''
select ifnull(NULL,'THIS IS NULL');-- More clearly....

The ifnull() function returns a copy of its first non-NULL argument, or NULL if both arguments are NULL. Ifnull() must have exactly 2 arguments. The ifnull() function is equivalent to coalesce() with two arguments.

Just ran into the problem today.

Troubleshooting method: With SourceTree on Windows Servers, you may try to run it as an Administrator. That fixes my problem of "unable to update local ref" on Atlassian Source Tree 2.1.2.5 on a Windows Server 2012 R2 in domain.

If you can too replicate this situation, it proves that the problem is caused by permission issue. It's better to drill down and find the root cause - probably some particular files are owned by other users and such - otherwise there's an unwelcome side-effect: you'll have to run SourceTree as Administrator for the rest of eternity.

Locate your ipython binary. If you have used anaconda to install ipython-notebook on a mac, chances are it will be in the /Users/[name]/anaconda/bin/ directory

in that directory, instead of launching your notebook as

./ipython notebook

add a --notebook-dir=<unicode> option.

./ipython notebook --notebook-dir=u'../rel/path/to/your/python-notebooks'

I use a bashscript in my ipython bin directory to launch my notebooks:

DIR=$(dirname $0)
$DIR/ipython notebook --notebook-dir=u'../rel/path/to/your/python-notebooks'

Note - the path to the notebook dir is relative to the ipython bin directory.

  pause

A slight variation on Richards answer but readTree can take a string so you can simplify it to:

ObjectMapper mapper = new ObjectMapper();
JsonNode actualObj = mapper.readTree("{\"k1\":\"v1\"}");

How about:

myString.Any(x => Char.IsWhiteSpace(x))

Or if you like using the "method group" syntax:

myString.Any(Char.IsWhiteSpace)

I think the Vim documentation should've explained the meaning behind the naming of these commands. Just telling you what they do doesn't help you remember the names.

map is the "root" of all recursive mapping commands. The root form applies to "normal", "visual+select", and "operator-pending" modes. (I'm using the term "root" as in linguistics.)

noremap is the "root" of all non-recursive mapping commands. The root form applies to the same modes as map. (Think of the nore prefix to mean "non-recursive".)

(Note that there are also the ! modes like map! that apply to insert & command-line.)

See below for what "recursive" means in this context.

Prepending a mode letter like n modify the modes the mapping works in. It can choose a subset of the list of applicable modes (e.g. only "visual"), or choose other modes that map wouldn't apply to (e.g. "insert").

Use help map-modes will show you a few tables that explain how to control which modes the mapping applies to.

Mode letters:

• n: normal only
• v: visual and select
• o: operator-pending
• x: visual only
• s: select only
• i: insert
• c: command-line
• l: insert, command-line, regexp-search (and others. Collectively called "Lang-Arg" pseudo-mode)

"Recursive" means that the mapping is expanded to a result, then the result is expanded to another result, and so on.

The expansion stops when one of these is true:

1. the result is no longer mapped to anything else.
2. a non-recursive mapping has been applied (i.e. the "noremap" [or one of its ilk] is the final expansion).

At that point, Vim's default "meaning" of the final result is applied/executed.

"Non-recursive" means the mapping is only expanded once, and that result is applied/executed.

Example:

 nmap K H
 nnoremap H G
 nnoremap G gg

The above causes K to expand to H, then H to expand to G and stop. It stops because of the nnoremap, which expands and stops immediately. The meaning of G will be executed (i.e. "jump to last line"). At most one non-recursive mapping will ever be applied in an expansion chain (it would be the last expansion to happen).

The mapping of G to gg only applies if you press G, but not if you press K. This mapping doesn't affect pressing K regardless of whether G was mapped recursively or not, since it's line 2 that causes the expansion of K to stop, so line 3 wouldn't be used.

There might be a best way (like using the portable cin.get()), but a good way doesn't exist. A program that has done its job should quit and give its resources back to the computer.

And yes, any usage of system() leads to unportable code, as the parameter is passed to the shell that owns your process.

Having pausing-code in your source code sooner or later causes hassles:

• someone forgets to delete the pausing code before checking in
  • now all working mates have to wonder why the app does not close anymore
  • version history is tainted
• #define is hell
• it's annoying to anyone who runs your code from the console
• it's very, very, very annoying when trying to start and end your program from within a script; quadly annoying if your program is part of a pipeline in the shell, because if the program does not end, the shell script or pipeline won't, too

Instead, explore your IDE. It probably has an option not to close the console window after running. If not, it's a great justification to you as a developer worth her/his money to always have a console window open nearby.

Alternatively, you can make this a program option, but I personally have never seen a program with an option --keep-alive-when-dead.

Moral of the story: This is the user's problem, and not the program's problem. Don't taint your code.

You mentioned that PHP solutions were acceptable, and PHP does offer a way to accomplish this even though it only supports XPath v1.0. You can extend the XPath support to allow PHP function calls.

$xpathObj = new DOMXPath($docObj);
$xpathObj->registerNamespace('php','http://php.net/xpath'); // (required)
$xpathObj->registerPhpFunctions("strtolower"); // (leave empty to allow *any* PHP function)
$xpathObj->query('//CD[php:functionString("strtolower",@title) = "empire burlesque"]');

See the PHP registerPhpFunctions documentation for more examples. It basically demonstrates that "php:function" is for boolean evaluation and "php:functionString" is for string evaluation.
