I don't know if this helps but I just installed Server 2008 Express and was disappointed when I couldn't find the query analyzer but I was able to use the command line 'sqlcmd' to access my server. It is a pain to use but it works. You can write your code in a text file then import it using the sqlcmd command. You also have to end your query with a new line and type the word 'go'.

Example of query file named test.sql:
use master;
select name, crdate from sysdatabases where xtype='u' order by crdate desc;
go

Example of sqlcmd:
sqlcmd -S %computername%\RLH -d play -i "test.sql" -o outfile.sql & notepad outfile.sql

You can use boost lexical cast:

#include <boost/lexical_cast.hpp>

string v("0.6");
double dd = boost::lexical_cast<double>(v);
cout << dd << endl;

Note: boost::lexical_cast throws exception so you should be prepared to deal with it when you pass invalid value, try passing string("xxx")

Didn't understand much from your posts. My solution is

1. Cut the problematic folder and copy to some location.
2. Do Get Solution From Subversion into another working directory (just new one).
3. Add your saved folder to the new working copy and add it As Existing Project (if it's project as in my case).
4. Commit;

You can use this

@echo off
for /F %%i in ('dir /b "c:\test directory\*.*"') do (
   echo Folder is NON empty
   goto :EOF
)
echo Folder is empty or does not exist

Taken from here.

That should do what you need.

You can run conda install --file requirements.txt instead of the loop, but there is no target directory in conda install. conda install installs a list of packages into a specified conda environment.

For ASPNET MVC, we did the following:

1. By default, set SessionStateBehavior.ReadOnly on all controller's action by overriding DefaultControllerFactory
2. On controller actions that need writing to session state, mark with attribute to set it to SessionStateBehavior.Required

Create custom ControllerFactory and override GetControllerSessionBehavior.

    protected override SessionStateBehavior GetControllerSessionBehavior(RequestContext requestContext, Type controllerType)
    {
        var DefaultSessionStateBehaviour = SessionStateBehaviour.ReadOnly;

        if (controllerType == null)
            return DefaultSessionStateBehaviour;

        var isRequireSessionWrite =
            controllerType.GetCustomAttributes<AcquireSessionLock>(inherit: true).FirstOrDefault() != null;

        if (isRequireSessionWrite)
            return SessionStateBehavior.Required;

        var actionName = requestContext.RouteData.Values["action"].ToString();
        MethodInfo actionMethodInfo;

        try
        {
            actionMethodInfo = controllerType.GetMethod(actionName, BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance);
        }
        catch (AmbiguousMatchException)
        {
            var httpRequestTypeAttr = GetHttpRequestTypeAttr(requestContext.HttpContext.Request.HttpMethod);

            actionMethodInfo =
                controllerType.GetMethods().FirstOrDefault(
                    mi => mi.Name.Equals(actionName, StringComparison.CurrentCultureIgnoreCase) && mi.GetCustomAttributes(httpRequestTypeAttr, false).Length > 0);
        }

        if (actionMethodInfo == null)
            return DefaultSessionStateBehaviour;

        isRequireSessionWrite = actionMethodInfo.GetCustomAttributes<AcquireSessionLock>(inherit: false).FirstOrDefault() != null;

         return isRequireSessionWrite ? SessionStateBehavior.Required : DefaultSessionStateBehaviour;
    }

    private static Type GetHttpRequestTypeAttr(string httpMethod) 
    {
        switch (httpMethod)
        {
            case "GET":
                return typeof(HttpGetAttribute);
            case "POST":
                return typeof(HttpPostAttribute);
            case "PUT":
                return typeof(HttpPutAttribute);
            case "DELETE":
                return typeof(HttpDeleteAttribute);
            case "HEAD":
                return typeof(HttpHeadAttribute);
            case "PATCH":
                return typeof(HttpPatchAttribute);
            case "OPTIONS":
                return typeof(HttpOptionsAttribute);
        }

        throw new NotSupportedException("unable to determine http method");
    }

AcquireSessionLockAttribute

[AttributeUsage(AttributeTargets.Method)]
public sealed class AcquireSessionLock : Attribute
{ }

Hook up the created controller factory in global.asax.cs

ControllerBuilder.Current.SetControllerFactory(typeof(DefaultReadOnlySessionStateControllerFactory));

Now, we can have both read-only and read-write session state in a single Controller.

public class TestController : Controller 
{
    [AcquireSessionLock]
    public ActionResult WriteSession()
    {
        var timeNow = DateTimeOffset.UtcNow.ToString();
        Session["key"] = timeNow;
        return Json(timeNow, JsonRequestBehavior.AllowGet);
    }

    public ActionResult ReadSession()
    {
        var timeNow = Session["key"];
        return Json(timeNow ?? "empty", JsonRequestBehavior.AllowGet);
    }
}

Note: ASPNET session state can still be written to even in readonly mode and will not throw any form of exception (It just doesn't lock to guarantee consistency) so we have to be careful to mark AcquireSessionLock in controller's actions that require writing session state.

To support the answer by @oberstet, if the cert is not trusted by the browser (for example you get a "this site is not secure, do you want to continue?") one solution is to open the browser options, navigate to the certificates settings and add the host and post that the websocket server is being served from to the certificate provider as an exception.

for example add 'example-wss-domain.org:6001' as an exception to 'Certificate Provider Ltd'.

In firefox, this can be done from 'about:preferences' and searching for 'Certificates'

Quite old post, but it might help somebody new into git.

I will go with

git rebase master

• much cleaner log history and no merge commits (if done properly)
• need to deal with conflicts, but it's not that difficult.

<!DOCTYPE html>

Otherwise IE8 is not acting right. Also you should use:

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />

Here is a sed solution:

sed '/19:55/{
N
N
N
N
N
s/\n/ /g
}' file.txt

Using SaSS
change the brand color

$brand-primary:#some-color;

this will change the primary color accross all UI.

Using css-
suppose you want to change button primary color.So

btn.primary{
  background:#some-color;
}

search the element and add a new css/sass rule in a new file and attach it after u load the bootstrap css.

For Windows do the following:

1. Note down the font name and font size from the "Edit-Select Font..." menu of "gvim.exec".
2. Then do :e $MYGVIMRC
3. Search for "guifont" string and change it to set guifont=<font name as noted>:h<font size>
4. Save the file and quit.
5. Next time when you execute gvim.exec, you will see the effect.

The server directive has to be in the http directive. It should not be outside of it.

Incase if you need detailed information, refer this.

If you are using an executable,

• just run the executable (for example: "en_sql_server_2012_express_edition_with_advanced_services_x64.exe")
• Navigate to the "options" tab
• Copy the "Installation Media Root Directory" (should look something like the below snipping)
• Paste it into the open "Browse for SQL server Installation Media" window

Save yourself the hastle of renaming and unzipping etc.!

Suppose you have void method that prints many objects;

public static void print( Object... values){
   for(Object c : values){
      System.out.println(c);
   }
}

Above example I used vararge as an argument that accepts values from 0 to N.

From comments: What if 2 strings and 5 integers ??

Answer:

print("string1","string2",1,2,3,4,5);

for Chinese user, just add two lines below to you config/application.rb :

config.active_record.default_timezone = :local
config.time_zone = 'Beijing'

I found it. Perl has multi-line comments:

#!/usr/bin/perl

use strict;

use warnings;

=for comment

Example of multiline comment.

Example of multiline comment.

=cut

print "Multi Line Comment Example \n";

Try changing the second parameter in the SaveAs call to Excel.XlFileFormat.xlWorkbookDefault.

When I did that, I generated an xlsx file that I was able to successfully open. (Before making the change, I could produce an xlsx file, but I was unable to open it.)

Also, I'm not sure if it matters or not, but I'm using the Excel 12.0 object library.

@gdbj's answer is a great explanation and the most up to date answer. Here's however a simpler approach.

So if you want to redirect all traffic from nginx listening to 80 to another container exposing 8080, minimum configuration can be as little as:

nginx.conf:

server {
    listen 80;

    location / {
        proxy_pass http://client:8080; # this one here
        proxy_redirect off;
    }

}

docker-compose.yml

version: "2"
services:
  entrypoint:
    image: some-image-with-nginx
    ports:
      - "80:80"
    links:
      - client  # will use this one here

  client:
    image: some-image-with-api
    ports:
      - "8080:8080"

UPDATE: Another writeup here: How to add publisher in Installshield 2018 (might be better).

I am not too well informed about this issue, but please see if this answer to another question tells you anything useful (and let us know so I can evolve a better answer here): How to pass the Windows Defender SmartScreen Protection? That question relates to BitRock - a non-MSI installer technology, but the overall issue seems to be the same.

Extract from one of the links pointed to in my answer above: "...a certificate just isn't enough anymore to gain trust... SmartScreen is reputation based, not unlike the way StackOverflow works... SmartScreen trusts installers that don't cause problems. Windows machines send telemetry back to Redmond about installed programs and how much trouble they cause. If you get enough thumbs-up then SmartScreen stops blocking your installer automatically. This takes time and lots of installs to get sufficient thumbs. There is no way to find out how far along you got."

Honestly this is all news to me at this point, so do get back to us with any information you dig up yourself.

The actual dialog text you have marked above definitely relates to the Zone.Identifier alternate data stream with a value of 3 that is added to any file that is downloaded from the Internet (see linked answer above for more details).

I was not able to mark this question as a duplicate of the previous one, since it doesn't have an accepted answer. Let's leave both question open for now? (one question is for MSI, one is for non-MSI).

Use \overset{above}{main} in math mode. In your case, \overset{a}{\#}.

Given an input file with four billion integers, provide an algorithm to generate an integer which is not contained in the file. Assume you have 1 GiB memory. Follow up with what you would do if you have only 10 MiB of memory.

The size of the file is 4 * 109 * 4 bytes = 16 GiB

In case of 32-bit Unsigned Integer

0 <= Number < 2^32
0 <= Number < 4,294,967,296

My proposed solution: C++ without error checking

#include <vector>
#include <fstream>
#include <iostream>
using namespace std;

int main ()
{
    const long SIZE = 1L << 32;

    std::vector<bool> checker(SIZE, false);

    std::ifstream infile("file.txt");  // TODO: error checking

    unsigned int num = 0;

    while (infile >> num)
    {
        checker[num] = true ;
    }

    infile.close();

    // print missing numbers

    for (long i = 0; i < SIZE; i++)
    {
        if (!checker[i])
            cout << i << endl ;
    }

    return 0;
}

Complexity

• Space ~ 2³² bits = 2²⁹ Bytes = 2¹⁹ KB = 2⁹ MB = 1/2 GB
• Time ~ Single Pass
• Completeness ~ Yes

d = {'A': 4,'B':10}

min_v = min(zip(d.values(), d.keys()))
# min_v is (4,'A')

max_v = max(zip(d.values(), d.keys()))
# max_v is (10,'B')

To my knowledge there is no cross-browser compatible way to make a circle with CSS & HTML only.

For the square I guess you could make a div with a border and a z-index higher than what you are putting it over. I don't understand why you would need to do this, when you could just put a border on the image or "something" itself.

If anyone else knows how to make a circle that is cross browser compatible with CSS & HTML only, I would love to hear about it!

@Caspar Kleijne border-radius does not work in IE8 or below, not sure about 9.

check your casing, the name is typically stored in upper case

SELECT * FROM all_source WHERE name = 'DAILY_UPDATE' ORDER BY TYPE, LINE;

ES2015 UPDATE

ES2015 have String#includes method that checks whether a string contains another. This can be used if the target environment supports it. The method returns true if the needle is found in haystack else returns false.

ng-if="haystack.includes(needle)"

Here, needle is the string that is to be searched in haystack.

See Browser Compatibility table from MDN. Note that this is not supported by IE and Opera. In this case polyfill can be used.

You can use String#indexOf to get the index of the needle in haystack.

1. If the needle is not present in the haystack -1 is returned.
2. If needle is present at the beginning of the haystack 0 is returned.
3. Else the index at which needle is, is returned.

The index can be compared with -1 to check whether needle is found in haystack.

ng-if="haystack.indexOf(needle) > -1" 

For Angular(2+)

*ngIf="haystack.includes(needle)"

There are many quirks in the way browsers handle XMLHttpRequest, this JS code will work across all browsers:
https://github.com/ilinsky/xmlhttprequest

This JS code converts XML into easy to use JavaScript objects:
http://www.terracoder.com/index.php/xml-objectifier

The JS code above can be included in the page to meet your no external library requirement.

var symbol = "MSFT"; 
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("POST", "http://www.webservicex.net/stockquote.asmx?op=GetQuote",true);
xmlhttp.onreadystatechange=function() {
 if (xmlhttp.readyState == 4) {
  alert(xmlhttp.responseText);
  // http://www.terracoder.com convert XML to JSON 
  var json = XMLObjectifier.xmlToJSON(xmlhttp.responseXML);
  var result = json.Body[0].GetQuoteResponse[0].GetQuoteResult[0].Text;
  // Result text is escaped XML string, convert string to XML object then convert to JSON object
  json = XMLObjectifier.xmlToJSON(XMLObjectifier.textToXML(result));
  alert(symbol + ' Stock Quote: $' + json.Stock[0].Last[0].Text); 
 }
}
xmlhttp.setRequestHeader("SOAPAction", "http://www.webserviceX.NET/GetQuote");
xmlhttp.setRequestHeader("Content-Type", "text/xml");
var xml = '<?xml version="1.0" encoding="utf-8"?>' +
 '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" ' +
                'xmlns:xsd="http://www.w3.org/2001/XMLSchema" ' +
                'xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">' + 
   '<soap:Body> ' +
     '<GetQuote xmlns="http://www.webserviceX.NET/"> ' +
       '<symbol>' + symbol + '</symbol> ' +
     '</GetQuote> ' +
   '</soap:Body> ' +

xmlhttp.send(xml);
// ...Include Google and Terracoder JS code here...

Two other options:

• JavaScript SOAP client:

• Generate JavaScript from a WSDL:

Place the following in your jQuery mouseover event handler:

$(this).css('color', 'red');

To set both color and size at the same time:

$(this).css({ 'color': 'red', 'font-size': '150%' });

You can set any CSS attribute using the .css() jQuery function.

for k, v in mydict.iteritems():
    if v is None:
        mydict[k] = ''

In a more general case, e.g. if you were adding or removing keys, it might not be safe to change the structure of the container you're looping on -- so using items to loop on an independent list copy thereof might be prudent -- but assigning a different value at a given existing index does not incur any problem, so, in Python 2.any, it's better to use iteritems.

In Python3 however the code gives AttributeError: 'dict' object has no attribute 'iteritems' error. Use items() instead of iteritems() here.

Refer to this post.

Usage depends on whether the component's parent has a layout manager or not.

• setSize() -- use when a parent layout manager does not exist;
• setPreferredSize() (also its related setMinimumSize and setMaximumSize) -- use when a parent layout manager exists.

The setSize() method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrames and JWindows) and things that are inside of scrolled panes. You also must call setSize() if you've got components inside a parent without a layout manager.

Generally, setPreferredSize() will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize() and setLocation() to position those components according to the layout's rules.

For example, a BorderLayout tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame, the size of the other components in the layout, and so on.

What you have is a parse error. Those are thrown before any code is executed. A PHP file needs to be parsed in its entirety before any code in it can be executed. If there's a parse error in the file where you're setting your error levels, they won't have taken effect by the time the error is thrown.

Either break your files up into smaller parts, like setting the error levels in one file and then includeing another file which contains the actual code (and errors), or set the error levels outside PHP using php.ini or .htaccess directives.

How about Freebase? I think they have an API available, too.

http://www.freebase.com/

How about this:

import sys
import subprocess

theproc = subprocess.Popen("myscript.py", shell = True)
theproc.communicate()                   # ^^^^^^^^^^^^

This tells subprocess to use the OS shell to open your script, and works on anything that you can just run in cmd.exe.

Additionally, this will search the PATH for "myscript.py" - which could be desirable.

I tried all the suggestions mentioned above and nothing worked. I terminated the current instance, launched another one and repeated the same exact process. This time no problems. Sometimes it might be the remote ami's fault.

There is another way to do this.

From iTerm2 2.9.20140923 you can use Dynamic Profiles as stated in the documentation page:

Dynamic Profiles is a feature that allows you to store your profiles in a file outside the usual macOS preferences database. Profiles may be changed at runtime by editing one or more plist files (formatted as JSON, XML, or in binary). Changes are picked up immediately.

So it is possible to create a file like this one:

    {
        "Profiles": [{
                "Name": "MYSERVER1",
                "Guid": "MYSERVER1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "M",
                "Tags": [
                    "LOCAL", "THATCOMPANY", "WORK", "NOCLOUD"
                ],
                "Badge Text": "SRV1",
            },
            {
                "Name": "MYOCEANSERVER1",
                "Guid": "MYOCEANSERVER1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "O",
                "Tags": [
                    "THATCOMPANY", "WORK", "DIGITALOCEAN"
                ],
                "Badge Text": "PPOCEAN1",
            },
            {
                "Name": "PI1",
                "Guid": "PI1",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "1",
                "Tags": [
                    "LOCAL", "PERSONAL", "RASPBERRY", "SMALL"
                ],
                "Badge Text": "LocalServer",
            },
            {
                "Name": "VUZERO",
                "Guid": "VUZERO",
                "Custom Command": "Yes",
                "Command": "ssh [email protected]",
                "Shortcut": "0",
                "Tags": [
                    "LOCAL", "PERSONAL", "SMALL"
                ],
                "Badge Text": "TeleVision",
            }
        ]
    }

in the folder ~/Library/Application\ Support/iTerm2/DynamicProfiles/ and share it across different machines. This enables you to retain some visual differences among iterm2 installations such as font type or dimension, while synchronising remote hosts, shortcuts, commands, and even a small badge to quickly identify a session

Solutions to apply during a loop:

//1 - Using conditional:

$source = array (1,2,3);
$total = count($source);
    
$str = null;
    
for($i=0; $i <= $total; $i++){ 
        
    if($i < $total) {
        $str .= $i.',';
    }
    else {
        $str .= $i;
    }
}
    
echo $str; //0,1,2,3

//2 - Using rtrim:

$source = array (1,2,3);
$total = count($source);

$str = null;

for($i=0; $i <= $total; $i++){ 
    
        $str .= $i.',';
}

$str = substr($str,0,strlen($str)-1);
echo $str; //0,1,2,3

All previously proposed approaches didn't satisfy my requirements for getting a complete URL (complete as in qualified) e.g. to be used in an email send from controller action. I need the scheme and hostname as well then, and thus stumbled over the following approach:

<?php echo Router::url( array( $id ), true ) ?>

Due to providing router array current controller and action is kept, however id isn't and thus has to be provided here again. Second argument true is actually requesting to prepend hostname etc. for getting full URL.

Using Router::url() is available in every situation and thus can be used in view files as well.

An alternative to cat() is writeLines():

> writeLines("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename
>

An advantage is that you don't have to remember to append a "\n" to the string passed to cat() to get a newline after your message. E.g. compare the above to the same cat() output:

> cat("File not supplied.\nUsage: ./program F=filename")
File not supplied.
Usage: ./program F=filename>

and

> cat("File not supplied.\nUsage: ./program F=filename","\n")
File not supplied.
Usage: ./program F=filename
>

The reason print() doesn't do what you want is that print() shows you a version of the object from the R level - in this case it is a character string. You need to use other functions like cat() and writeLines() to display the string. I say "a version" because precision may be reduced in printed numerics, and the printed object may be augmented with extra information, for example.

You should also mind the references to other objects.

If the table was highly referenced by other tables than it’s probably also highly referenced by other objects such as views, stored procedures, functions and more.

I’d really recommend GUI tool such as ‘view dependencies’ dialog in SSMS or free tool like ApexSQL Search for this because searching for dependencies in other objects can be error prone if you want to do it only with SQL.

If SQL is the only option you could try doing it like this.

select O.name as [Object_Name], C.text as [Object_Definition]
from sys.syscomments C
inner join sys.all_objects O ON C.id = O.object_id
where C.text like '%table_name%'

The way you're doing it you're querying for the process twice. Also Lynn raises a good point about being nice first. I'd probably try something like the following:

# get Firefox process
$firefox = Get-Process firefox -ErrorAction SilentlyContinue
if ($firefox) {
  # try gracefully first
  $firefox.CloseMainWindow()
  # kill after five seconds
  Sleep 5
  if (!$firefox.HasExited) {
    $firefox | Stop-Process -Force
  }
}
Remove-Variable firefox

Thank you Marcosc! Building on his answer, if you want to rename any function, use this:

// returns the function named with the passed name
function namedFunction(name, fn) {
    return new Function('fn',
        "return function " + name + "(){ return fn.apply(this,arguments)}"
    )(fn)
}

In my case, the host was unkown and instead of typing yes to the question are you sure you want to continue connecting(yes/no/[fingerprint])? I was just hitting enter .

Thanks for the earlier reply.

I figured out the solutions using selenium 2.0 classes.

import java.util.List;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.ie.InternetExplorerDriver;

public class WebTableExample 
{
    public static void main(String[] args) 
    {
        WebDriver driver = new InternetExplorerDriver();
        driver.get("http://localhost/test/test.html");      

        WebElement table_element = driver.findElement(By.id("testTable"));
        List<WebElement> tr_collection=table_element.findElements(By.xpath("id('testTable')/tbody/tr"));

        System.out.println("NUMBER OF ROWS IN THIS TABLE = "+tr_collection.size());
        int row_num,col_num;
        row_num=1;
        for(WebElement trElement : tr_collection)
        {
            List<WebElement> td_collection=trElement.findElements(By.xpath("td"));
            System.out.println("NUMBER OF COLUMNS="+td_collection.size());
            col_num=1;
            for(WebElement tdElement : td_collection)
            {
                System.out.println("row # "+row_num+", col # "+col_num+ "text="+tdElement.getText());
                col_num++;
            }
            row_num++;
        } 
    }

import sys
sys.exit()

details from the sys module documentation:

sys.exit([arg])

Exit from Python. This is implemented by raising the SystemExit exception, so cleanup actions specified by finally clauses of try statements are honored, and it is possible to intercept the exit attempt at an outer level.

The optional argument arg can be an integer giving the exit status (defaulting to zero), or another type of object. If it is an integer, zero is considered “successful termination” and any nonzero value is considered “abnormal termination” by shells and the like. Most systems require it to be in the range 0-127, and produce undefined results otherwise. Some systems have a convention for assigning specific meanings to specific exit codes, but these are generally underdeveloped; Unix programs generally use 2 for command line syntax errors and 1 for all other kind of errors. If another type of object is passed, None is equivalent to passing zero, and any other object is printed to stderr and results in an exit code of 1. In particular, sys.exit("some error message") is a quick way to exit a program when an error occurs.

Since exit() ultimately “only” raises an exception, it will only exit the process when called from the main thread, and the exception is not intercepted.

Note that this is the 'nice' way to exit. @glyphtwistedmatrix below points out that if you want a 'hard exit', you can use os._exit(*errorcode*), though it's likely os-specific to some extent (it might not take an errorcode under windows, for example), and it definitely is less friendly since it doesn't let the interpreter do any cleanup before the process dies. On the other hand, it does kill the entire process, including all running threads, while sys.exit() (as it says in the docs) only exits if called from the main thread, with no other threads running.

Here's some simple JavaScript code that doesn't require the developer to edit CSS or write any new CSS rules. I wrote this for Bootstrap buttons with class="btn", but it will work with any button that has a specific class name.

The steps are:

1. determine if this is a touch device
2. if it is, iterate over every CSS rule in document.styleSheets
3. delete any rule containing both .btn and :hover

The elimination of all .btn :hover CSS rules ensures that there will be no visual hover effect on a button.

Step 1: Detect Touch Device

Check media query for presence of (hover: none):

    const hasMatchMedia = typeof window.matchMedia !== 'undefined';
    /**
     * determine if device is touch-capable
     * true - device is touch-capable
     * false - device is not touch-capable
     * null - unable to determine touch capability
     * @return {null|boolean}
     */
    const hasTouch = () => {
      if (hasMatchMedia) {
        return window.matchMedia('(hover: none)').matches;
      }
      return null;
    };

Step 2: Delete CSS Rules Containing `btn` and `:hover`

    /**
     * remove all CSS rules contaning both '.btn' and ':hover'
     * @return {number} count of rules deleted
     */
    function removeBtnHovers () {

      let rulesDeleted = 0;

      // recursively delete '.btn:hover' rules
      function recursiveDelete (rules, styleSheet) {

        if (typeof rules === 'undefined' ||
          typeof rules.length === 'undefined' ||
          rules.length <= 0) {
          return;
        }

        // iterate in reverse order,
        // deleting any rule containing both '.btn' and ':hover'
        const ruleLen = rules.length;
        for (let i = ruleLen - 1; i >= 0; i--) {
          const rule = rules[i];
          if (typeof rule.cssRules === 'undefined') {
            // a standard rule, evaluate it
            const cssText = rule.cssText;
            if (typeof cssText === 'string' &&
              cssText.includes('.btn') &&
              cssText.includes(':hover')) {
              styleSheet.deleteRule(i);
              rulesDeleted++;
            }
          } else {
            // rule contains cssRules, iterate over them
            recursiveDelete(rule.cssRules, rule);
          }
        }
      }

      // iterate over all style sheets in document
      for (const styleSheet of document.styleSheets) {
        let rules = styleSheet.cssRules;
        if (!rules) { continue; }
        recursiveDelete(rules, styleSheet);
      }
      return rulesDeleted;
    }

When the directory is deleted, the inode for that directory (and the inodes for its contents) are recycled. The pointer your shell has to that directory's inode (and its contents's inodes) are now no longer valid. When the directory is restored from backup, the old inodes are not (necessarily) reused; the directory and its contents are stored on random inodes. The only thing that stays the same is that the parent directory reuses the same name for the restored directory (because you told it to).

Now if you attempt to access the contents of the directory that your original shell is still pointing to, it communicates that request to the file system as a request for the original inode, which has since been recycled (and may even be in use for something entirely different now). So you get a stale file handle message because you asked for some nonexistent data.

When you perform a cd operation, the shell reevaluates the inode location of whatever destination you give it. Now that your shell knows the new inode for the directory (and the new inodes for its contents), future requests for its contents will be valid.

For those who are still stumped with this problem (I tried all the above suggestions) --

If you're on a 64-bit version of Windows and you've installed the 32-bit JDK, besides adjusting PATH variables, you may need to adjust registry variables, too.

I was pulling my hair out, having correctly set my PATH variables -- still to no avail -- and then only finding "vacated" Java entries in my registry, seemingly a deadend of fixing the "misfiring" Java Runtime Environment.

By using Process Monitor to watch the program I was trying to get started, in order to sniff out where it was looking in the registry for Java (Runtime Environment), I triumphantly discovered that it's looking in the 32-bit version of registry entries, found in HKEY_LOCAL_MACHINE\SOFTWARE\**Wow6432Node**\JavaSoft\Java Runtime Environment.

Within that key, you should find subkeys of different Java versions installed (past and/or present). Click on the subkey of the latest version (my subkey is currently 1.7.0_25, for example). After clicking on that subkey, you'll see registry string values listed on the right, and particularly, JavaHome and RuntimeLib. You need to modify the values of those two values to reflect the both the current folder and jvm.dll file, respectively.

For example, in my case, the values were (previously) respectively set at C:\Program Files (x86)\Java\jre7 and C:\Program Files (x86)\Java\jre7\bin\client\jvm.dll which are nonexistent on my machine. I had to update these to the current folder and file of C:\Program Files (x86)\Java\jdk1.7.0_25\jre and C:\Program Files (x86)\Java\jdk1.7.0_25\jre\bin\client\jvm.dll.

Again, this will depend entirely on both what version of Java (JDK and/or JRE) you have installed -- 32 or 64-bit -- and what type of operating system you're on -- 32 or 64-bit. Just know that they're reflected in different locations within the registry (like the Wow6432Node for 32 bit applications, in my case with the 32-bit JDK installed on a 64-bit machine).

Now that I've updated those two registry values, my program runs flawlessly, with no more hiccups or complaints about a missing Java Runtime Environment (stemming from the registry).

ls=['hello','world']
ls.append('python')
['hello', 'world', 'python']

or (use insert function where you can use index position in list)

ls.insert(0,'python')
print(ls)
['python', 'hello', 'world']

Greg is right-- you can use sys.stdout.write

Perhaps, though, you should consider refactoring your algorithm to accumulate a list of <whatevers> and then

lst = ['h', 'm']
print  "".join(lst)

Bash -ge 4 has the mapfile builtin to read lines from the standard input into an array variable.

help mapfile 

mapfile < file.txt lines
printf "%s" "${lines[@]}"

mapfile -t < file.txt lines    # strip trailing newlines
printf "%s\n" "${lines[@]}" 

See also:

http://bash-hackers.org/wiki/doku.php/commands/builtin/mapfile

var myError = new Error('foo');
myError instanceof Error // true
var myString = "Whatever";
myString instanceof Error // false

Only problem with this is

myError instanceof Object // true

An alternative to this would be to use the constructor property.

myError.constructor === Object // false
myError.constructor === String // false
myError.constructor === Boolean // false
myError.constructor === Symbol // false
myError.constructor === Function // false
myError.constructor === Error // true

Although it should be noted that this match is very specific, for example:

myError.constructor === TypeError // false

You need to declare an array in another array.

$arr = array(array(content), array(content));

Example:

$arr = array(array(1,2,3), array(4,5,6));

To get the first item from the array, you'll use $arr[0][0], that's like the first item from the first array from the array. $arr[1][0] will return the first item from the second array from the array.

uese following code.

 NSString *searchText = @"Bhupi"
 NSString *formatedSearchText = [NSString stringWithFormat:@"%%%@%%",searchText];

will output: %Bhupi%

Theoretically, you can compare edit distances.

The nearest equivalents would be icode and bcode as used by scalac, view Miguel Garcia's site on the Scalac optimiser for more information, here: http://magarciaepfl.github.io/scala/

You might also consider Java bytecode itself to be your intermediate representation, given that bytecode is the ultimate output of scalac.

Or perhaps the true intermediate is something that the JIT produces before it finally outputs native instructions?

Ultimately though... There's no single place that you can point at an claim "there's the intermediate!". Scalac works in phases that successively change the abstract syntax tree, every single phase produces a new intermediate. The whole thing is like an onion, and it's very hard to try and pick out one layer as somehow being more significant than any other.

Swift 4+:

Add following lines in your table cell

let bgColorView = UIView()
bgColorView.backgroundColor =  .red
self.selectedBackgroundView = bgColorView

Finally it should be as below

override func setSelected(_ selected: Bool, animated: Bool)
    {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
        let bgColorView = UIView()
        bgColorView.backgroundColor =  .red
        self.selectedBackgroundView = bgColorView

    }

I would like to add to the answers of BalusC and Pascal Thivent another common use of insertable=false, updatable=false:

Consider a column that is not an id but some kind of sequence number. The responsibility for calculating the sequence number may not necessarily belong to the application.

For example, sequence number starts with 1000 and should increment by one for each new entity. This is easily done, and very appropriately so, in the database, and in such cases these configurations makes sense.

There is a operator < between lists e.g.:

[12, 'tall', 'blue', 1] < [4, 'tall', 'blue', 13]

will give

False

Supply the public rsa key of the host :-

String knownHostPublicKey = "mywebsite.com ssh-rsa AAAAB3NzaC1.....XL4Jpmp/";

session.setKnownHosts(new ByteArrayInputStream(knownHostPublicKey.getBytes()));

Use unidecode - it even converts weird characters to ascii instantly, and even converts Chinese to phonetic ascii.

$ pip install unidecode

then:

>>> from unidecode import unidecode
>>> unidecode(u'??')
'Bei Jing'
>>> unidecode(u'Škoda')
'Skoda'

                    anyDateInMonth.getMonth()+1,

<android.support.v7.widget.Toolbar

That toolbar theme specifies a textColorPrimary and textColorSecondary to change the color of the title text and of the menu overflow button. You could just specify the standard Theme.AppCompat.Light.NoActionBar theme for the toolbar, to get the dark text and overflow icon, but I wanted to derive from my own theme and make only small changes, because I have no idea what else might be affected.

<style name="GalaxyZooThemeToolbarDarkOverflow" parent="Theme.AppCompat.NoActionBar">


<!-- android:textColorPrimary is the  color of the title text

<!-- android:textColorPrimaryInverse is the  color of the title
   text in the Toolbar, in the Theme.AppCompat.Light theme:  -->


<!-- <item name="android:textColorPrimaryInverse">@color/abc_primary_text_material_light</item> -->

This is how you can change the color of text and icons on toolbar.

TL;DR

SQLCMD -S (LOCAL) -E -V 16 -Q "IF(ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT),0)<11) RAISERROR('You need SQL 2012 or later!',16,1)"
IF ERRORLEVEL 1 GOTO :ExitFail

This uses SQLCMD (comes with SQL Server) to connect to the local server instance using Windows auth, throw an error if a version check fails and return the @@ERROR as the command line ERRORLEVEL if >= 16 (and the second line goes to the :ExitFail label if the aforementioned ERRORLEVEL is >= 1).

Watchas, Gotchas & More Info

For SQL 2000+ you can use the SERVERPROPERTY to determine a lot of this info.

While SQL 2008+ supports the ProductMajorVersion & ProductMinorVersion properties, ProductVersion has been around since 2000 (remembering that if a property is not supported the function returns NULL).

If you are interested in earlier versions you can use the PARSENAME function to split the ProductVersion (remembering the "parts" are numbered right to left i.e. PARSENAME('a.b.c', 1) returns c).

Also remember that PARSENAME('a.b.c', 4) returns NULL, because SQL 2005 and earlier only used 3 parts in the version number!

So for SQL 2008+ you can simply use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(SERVERPROPERTY('ProductMajorVersion')  AS INT) AS ProductMajorVersion,
    CAST(SERVERPROPERTY ('ProductMinorVersion') AS INT) AS ProductMinorVersion;

For SQL 2000-2005 you can use:

SELECT
    SERVERPROPERTY('ProductVersion') AS ProductVersion,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) AS ProductVersion_Major,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 3 END) AS INT) AS ProductVersion_Minor,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 1 ELSE 2 END) AS INT) AS ProductVersion_Revision,
    CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 0 ELSE 1 END) AS INT) AS ProductVersion_Build;

(the PARSENAME(...,0) is a hack to improve readability)

So a check for a SQL 2000+ version would be:

IF (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) < 10) -- SQL2008
OR (
    (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 3 ELSE 4 END) AS INT) = 10) -- SQL2008
AND (CAST(PARSENAME(CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME), CASE WHEN SERVERPROPERTY('ProductVersion') IS NULL THEN 2 ELSE 1 END) AS INT) < 5)  -- R2 (this may need to be 50)
   )
    RAISERROR('You need SQL 2008R2 or later!', 16, 1);

This is a lot simpler if you're only only interested in SQL 2008+ because SERVERPROPERTY('ProductMajorVersion') returns NULL for earlier versions, so you can use:

IF (ISNULL(CAST(SERVERPROPERTY('ProductMajorVersion') AS INT), 0) < 11) -- SQL2012
    RAISERROR('You need SQL 2012 or later!', 16, 1);

And you can use the ProductLevel and Edition (or EngineEdition) properties to determine RTM / SPn / CTPn and Dev / Std / Ent / etc respectively.

SELECT
    CAST(SERVERPROPERTY('ProductVersion') AS SYSNAME) AS ProductVersion,
    CAST(SERVERPROPERTY('ProductLevel') AS SYSNAME)   AS ProductLevel,
    CAST(SERVERPROPERTY('Edition') AS SYSNAME)        AS Edition,
    CAST(SERVERPROPERTY('EngineEdition') AS INT)      AS EngineEdition;

FYI the major SQL version numbers are:

• 8 = SQL 2000
• 9 = SQL 2005
• 10 = SQL 2008 (and 10.5 = SQL 2008R2)
• 11 = SQL 2012
• 12 = SQL 2014
• 13 = SQL 2016
• 14 = SQL 2017

And this all works for SQL Azure too!

EDITED: You may also want to check your DB compatibility level since it could be set to a lower compatibility.

IF EXISTS (SELECT * FROM sys.databases WHERE database_id=DB_ID() AND [compatibility_level] < 110)
    RAISERROR('Database compatibility level must be SQL2008R2 or later (110)!', 16, 1)

If Character.isLetter(ch) looks a bit wordy/ugly you can use a static import.

import static java.lang.Character.*;


if(isLetter(ch)) {

} else if(isDigit(ch)) {

} 

If you need help with complex definitions, like

double (*(*pf)())[3][4];

take a look at my right-left rule here.

I am using JQuery > 1.8 and this works for me...

$('#dropDownId').attr('disabled', true);

if tableFields is an array , you can loop through elements as following :

for (item in tableFields); {
     console.log(tableFields[item]);
}

by the way i saw a logical error in you'r code.just remove ; from end of for loop

right here :

for (item in tableFields); { .

this will cause you'r loop to do just nothing.and the following line will be executed only once :

// Do stuff

The consequence of this is that you may need a rather insane-looking query, e. g.,

SELECT [dbo].[tblTimeSheetExportFiles].[lngRecordID]            AS lngRecordID
          ,[dbo].[tblTimeSheetExportFiles].[vcrSourceWorkbookName]  AS vcrSourceWorkbookName
          ,[dbo].[tblTimeSheetExportFiles].[vcrImportFileName]      AS vcrImportFileName
          ,[dbo].[tblTimeSheetExportFiles].[dtmLastWriteTime]       AS dtmLastWriteTime
          ,[dbo].[tblTimeSheetExportFiles].[lngNRecords]            AS lngNRecords
          ,[dbo].[tblTimeSheetExportFiles].[lngSizeOnDisk]          AS lngSizeOnDisk
          ,[dbo].[tblTimeSheetExportFiles].[lngLastIdentity]        AS lngLastIdentity

Since the primary table is a summary table, its primary key handles the only grouping or ordering that is truly necessary. Hence, the GROUP BY clause exists solely to satisfy the query parser.

The solution was as simple as adding plt.show() at the end of the code snippet:

import numpy as np
np.random.seed(123)
from keras.models import Sequential
from keras.layers import Dense, Dropout, Activation, Flatten
from keras.layers import Convolution2D, MaxPooling2D
from keras.utils import np_utils
from keras.datasets import mnist
(X_train,y_train),(X_test,y_test) = mnist.load_data()
print X_train.shape
from matplotlib import pyplot as plt
plt.imshow(X_train[0])
plt.show()

You use an implicit operator that converts the string value to a struct value:

public struct MyStruct {
  public string s;
  public int length;

  public static implicit operator MyStruct(string value) {
    return new MyStruct() { s = value, length = value.Length };
  }

}

Example:

MyStruct myStruct = "Lol";
Console.WriteLine(myStruct.s);
Console.WriteLine(myStruct.length);

Output:

Lol
3

Other solutions on this page aren't desirable if you have a long list of extensions -- maintaining a long sequence of -not -name 'this' -not -name 'that' -not -name 'other' would be tedious and error-prone -- or if the search is programmatic and the list of extensions is built at runtime.

For those situations, a solution that more clearly separates data (the list of extensions) and code (the parameters to find) may be desirable. Given a directory & file structure that looks like this:

.
+-- a
    +-- 1.txt
    +-- 15.xml
    +-- 8.dll
    +-- b
    ¦   +-- 16.xml
    ¦   +-- 2.txt
    ¦   +-- 9.dll
    ¦   +-- c
    ¦       +-- 10.dll
    ¦       +-- 17.xml
    ¦       +-- 3.txt
    +-- d
    ¦   +-- 11.dll
    ¦   +-- 18.xml
    ¦   +-- 4.txt
    ¦   +-- e
    ¦       +-- 12.dll
    ¦       +-- 19.xml
    ¦       +-- 5.txt
    +-- f
        +-- 13.dll
        +-- 20.xml
        +-- 6.txt
        +-- g
            +-- 14.dll
            +-- 21.xml
            +-- 7.txt

You can do something like this:

## data section, list undesired extensions here
declare -a _BADEXT=(xml dll)

## code section, this never changes
BADEXT="$( IFS="|" ; echo "${_BADEXT[*]}" | sed 's/|/\\|/g' )"
find . -type f ! -regex ".*\.\($BADEXT\)"

Which results in:

./a/1.txt
./a/b/2.txt
./a/b/c/3.txt
./a/d/4.txt
./a/d/e/5.txt
./a/f/6.txt
./a/f/g/7.txt

You can change the extensions list without changing the code block.

NOTE doesn't work with native OSX find - use gnu find instead.

Generally if the installation went smoothly, it will create the desktop icons/folders. Maybe check the installation summary log to see if there's any underlying errors.

It should be located C:\Program Files\Microsoft SQL Server\100\Setup Bootstrap\Log(date stamp)\

Hope it will help someone who encounter similar issue!

There are 2 options to find matching text; string.match or string.find.

Both of these perform a regex search on the string to find matches.

string.find()

string.find(subject string, pattern string, optional start position, optional plain flag)

Returns the startIndex & endIndex of the substring found.

The plain flag allows for the pattern to be ignored and intead be interpreted as a literal. Rather than (tiger) being interpreted as a regex capture group matching for tiger, it instead looks for (tiger) within a string.

Going the other way, if you want to regex match but still want literal special characters (such as .()[]+- etc.), you can escape them with a percentage; %(tiger%).

You will likely use this in combination with string.sub

Example

str = "This is some text containing the word tiger."
if string.find(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

string.match()

string.match(s, pattern, optional index)

Returns the capture groups found.

Example

str = "This is some text containing the word tiger."
if string.match(str, "tiger") then
  print ("The word tiger was found.")
else
  print ("The word tiger was not found.")
end

Try using getTime (mdn doc) :

var diff = Math.abs(date1.getTime() - date2.getTime()) / 3600000;
if (diff < 18) { /* do something */ }

Using Math.abs() we don't know which date is the smallest. This code is probably more relevant :

var diff = (date1 - date2) / 3600000;
if (diff < 18) { array.push(date1); }

What about -mmin?

find /var/www/html/audio -daystart -maxdepth 1 -mmin +59 -type f -name "*.mp3" \
    -exec rm -f {} \;

From man find:

-mmin n
        File's data was last modified n minutes ago.

Also, make sure to test this first!

... -exec echo rm -f '{}' \;
          ^^^^ Add the 'echo' so you just see the commands that are going to get
               run instead of actual trying them first.

For systems where the default Time Zone is not UTC:

TimeZone tz = TimeZone.getTimeZone("UTC");
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm'Z'");
df.setTimeZone(tz);
String nowAsISO = df.format(new Date());

The SimpleDateFormat instance may be declared as a global constant if needed frequently, but beware that this class is not thread-safe. It must be synchronized if accessed concurrently by multiple threads.

EDIT: I would prefer Joda Time if doing many different Times/Date manipulations...
EDIT2: corrected: setTimeZone does not accept a String (corrected by Paul)

it's not impossible:

var evObj = document.createEvent('MouseEvents');
evObj.initMouseEvent('click', true, true, window);  
setTimeout(function(){ document.getElementById('input_field_id').dispatchEvent(evObj); },100);

But somehow it works only if this is in a function which was called via a click-event.

So you might have following setup:

html:

<div onclick="openFileChooser()" class="some_fancy_stuff">Click here to open image chooser</div>
<input type="file" id="input_img">

JavaScript:

    function openFileChooser() {
      var evObj = document.createEvent('MouseEvents');
      evObj.initMouseEvent('click', true, true, window);  
      setTimeout(function()
      { 
        document.getElementById('input_img').dispatchEvent(evObj);      
      },100);      
    }

You can add escaped double quotes like this: String name = "\"john\"";

Here is my code, to make different colors on button, and Linear, Constraint and Scroll Layout

First, you need to make a custom_button.xml on your drawable

1. Go to res
2. Expand it, right click on drawable
3. New -> Drawable Resource File
4. File Name : custom_button, Click OK

Custom_Button.xml Code

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/red"/> <!-- pressed -->
    <item android:state_focused="true" android:drawable="@color/blue"/> <!-- focused -->
    <item android:drawable="@color/black"/> <!-- default -->
</selector>

Second, go to res

1. Expand values
2. Double click on colors.xml
3. Copy the code below

Colors.xml Code

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#3F51B5</color>
    <color name="colorPrimaryDark">#303F9F</color>
    <color name="colorAccent">#FF4081</color>

    <color name="black">#000</color>
    <color name="violet">#9400D3</color>
    <color name="indigo">#4B0082</color>
    <color name="blue">#0000FF</color>
    <color name="green">#00FF00</color>
    <color name="yellow">#FFFF00</color>
    <color name="orange">#FF7F00</color>
    <color name="red">#FF0000</color>
</resources>

Here is an example that calls another constructor, then checks on the property it has set.

    public SomeClass(int i)
    {
        I = i;
    }

    public SomeClass(SomeOtherClass soc)
        : this(soc.J)
    {
        if (I==0)
        {
            I = DoSomethingHere();
        }
    }

for Title Bar

requestWindowFeature(Window.FEATURE_NO_TITLE);

for fullscreen

getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
            WindowManager.LayoutParams.FLAG_FULLSCREEN);

Place this after

super.onCreate(savedInstanceState);

but before

setContentView(R.layout.xml);

This worked for me.try this

Single quotes work fine too, even without escaping the double quotes, at least in Excel 2016:

'text with spaces, and a comma','more text with spaces','spaces and "quoted text" and more spaces','nospaces','NOSPACES1234'

Excel will put that in 5 columns (if you choose the single quote as "Text qualifier" in the "Text to columns" wizard)

Since we all love one-liners

... this one depends on the Newtonsoft NuGet package, which is popular and better than the default serializer.

Linting is the process of running a program that will analyse code for potential errors.

See lint on wikipedia:

lint was the name originally given to a particular program that flagged some suspicious and non-portable constructs (likely to be bugs) in C language source code. The term is now applied generically to tools that flag suspicious usage in software written in any computer language.

One can replace unicode with u''.__class__ to handle the missing unicode class in Python 3. For both Python 2 and 3, you can use the construct

isinstance(unicode_or_str, u''.__class__)

or

type(unicode_or_str) == type(u'')

Depending on your further processing, consider the different outcome:

Python 3

>>> isinstance('text', u''.__class__)
True
>>> isinstance(u'text', u''.__class__)
True

Python 2

>>> isinstance(u'text', u''.__class__)
True
>>> isinstance('text', u''.__class__)
False

The below silent .bat file code prevents the need to have two bat files (using "goto" and ":").

It does it all in the same .bat file. Tested and confirmed working in Windows 10

Make sure you replace "C:\pathToFile\ThisBatFile.bat " with the path to this same .bat file! Keep the space after ".bat".

@echo off
if [%1]==[] (
    goto PreSilentCall
) else (
    goto SilentCall
)

:PreSilentCall
REM Insert code here you want to have happen BEFORE this same .bat file is called silently
REM such as setting paths like the below two lines

set WorkingDirWithSlash=%~dp0
set WorkingDirectory=%WorkingDirWithSlash:~0,-1%

REM below code will run this same file silently, but will go to the SilentCall section
cd C:\Windows\System32
if exist C:\Windows\Temp\invis.vbs ( del C:\Windows\Temp\invis.vbs /f /q )
echo CreateObject("Wscript.Shell").Run "C:\pathToFile\ThisBatFile.bat " ^& WScript.Arguments(0), 0, False > C:\Windows\Temp\invis.vbs
wscript.exe C:\Windows\Temp\invis.vbs Initialized
if %ERRORLEVEL%==0 (
    echo Successfully started SilentCall code. This command prompt can now be exited.
    goto Exit
)


:SilentCall
cd %WorkingDirectory%
REM Insert code you want to be done silently. 
REM Make sure this section has no errors as you won't be able to tell if there are any, 
REM since it will be running silently. You can add a greater than symbol at the end of
REM your commands in this section to output the results to a .txt file for the purpose 
REM of debugging this section of code.


:Exit

If your .bat file needs more than just the "Initialized" argument (which tells the bat file to go to :SilentCall section), add "^& WScript.Arguments(1)," , "^& WScript.Arguments(2)," ,etc. depending on the number of arguments, then edit the line where wscript.exe is called:

"wscript.exe C:\Windows\Temp\invis.vbs Initialized BatFileArgOne BatFileArgTwo"

In Rails 4.02+ according to the docs there is no method like update_all with 2 arguments. Instead one can use this code:

# Make sure no null value exist
MyModel.where(date_column: nil).update_all(date_column: Time.now)

# Change the column to not allow null
change_column :my_models, :date_column, :datetime, null: false

Although it doesn't make much difference on the way in, it does on the way back.

Sure you can use either '/' or '\' in new File(String path), but File.getPath() will only give you one of them.

i found i had to do something akin to

=(countifs (A1:A196,"yes", j1:j196, "agree") + (countifs (A1:A196,"no", j1:j196, "agree"))

I would suggest to use ExpectedConditions and alertIsPresent(). ExpectedConditions is a wrapper class that implements useful conditions defined in ExpectedCondition interface.

public boolean isAlertPresent(){
    boolean foundAlert = false;
    WebDriverWait wait = new WebDriverWait(driver, 0 /*timeout in seconds*/);
    try {
        wait.until(ExpectedConditions.alertIsPresent());
        foundAlert = true;
    } catch (TimeoutException eTO) {
        foundAlert = false;
    }
    return foundAlert;
}

Note: this is based on the answer by nilesh, but adapted to catch the TimeoutException which is thrown by the wait.until() method.

Please keep in mind: this is just a JavaScript thing and has nothing to do with Angular JS. So don't be confused about the magical '$' sign ;)

The main problem is that this is an hierarchical structure.

console.log($scope.life.meaning);  // <-- Nope! This is undefined.
=> a.b.c

This is undefined because "$scope.life" is not existing but the term above want to solve "meaning".

A solution should be

var the_string = 'lifeMeaning';
$scope[the_string] = 42;
console.log($scope.lifeMeaning);
console.log($scope['lifeMeaning']);

or with a little more efford.

var the_string_level_one = 'life';
var the_string_level_two = the_string_level_one + '.meaning';
$scope[the_string_level_two ] = 42;
console.log($scope.life.meaning);
console.log($scope['the_string_level_two ']);

Since you can access a structural objecte with

var a = {};
a.b = "ab";
console.log(a.b === a['b']);

There are several good tutorials about this which guide you well through the fun with JavaScript.

There is something about the

$scope.$apply();
do...somthing...bla...bla

Go and search the web for 'angular $apply' and you will find information about the $apply function. And you should use is wisely more this way (if you are not alreay with a $apply phase).

$scope.$apply(function (){
    do...somthing...bla...bla
})

this procedure has done very good for me in the last couple of years. to run it just type sp_radhe

Regarding putting sp_radhe in the master database

I use the following code and make it a system stored procedure

exec sys.sp_MS_marksystemobject 'sp_radhe'

as you can see on the link below

Creating Your Own SQL Server System Stored Procedures

Regarding the transaction isolation level

Questions About T-SQL Transaction Isolation Levels You Were Too Shy to Ask

Jonathan Kehayias

Once you change the transaction isolation level it only changes when the scope exits at the end of the procedure or a return call, or if you change it explicitly again using SET TRANSACTION ISOLATION LEVEL.

In addition the TRANSACTION ISOLATION LEVEL is only scoped to the stored procedure, so you can have multiple nested stored procedures that execute at their own specific isolation levels.

Look for an installation subdirectory, likely named eclipse. Under that subdirectory, if you see files like eclipse.ini, icon.xpm and subdirectories like plugins and dropins, remove the subdirectory parent (the one named eclipse).

That will remove your installation except for anything you've set up yourself (like workspaces, projects, etc.).

Hope this helps.

Your code is almost right! You are right, you are just missing one step. When you read in the file, you are reading it as a string; but you want to turn the string back into a dictionary.

The error message you saw was because self.whip was a string, not a dictionary.

I first wrote that you could just feed the string into dict() but that doesn't work! You need to do something else.

Example

Here is the simplest way: feed the string into eval(). Like so:

def reading(self):
    s = open('deed.txt', 'r').read()
    self.whip = eval(s)

You can do it in one line, but I think it looks messy this way:

def reading(self):
    self.whip = eval(open('deed.txt', 'r').read())

But eval() is sometimes not recommended. The problem is that eval() will evaluate any string, and if someone tricked you into running a really tricky string, something bad might happen. In this case, you are just running eval() on your own file, so it should be okay.

But because eval() is useful, someone made an alternative to it that is safer. This is called literal_eval and you get it from a Python module called ast.

import ast

def reading(self):
    s = open('deed.txt', 'r').read()
    self.whip = ast.literal_eval(s)

ast.literal_eval() will only evaluate strings that turn into the basic Python types, so there is no way that a tricky string can do something bad on your computer.

EDIT

Actually, best practice in Python is to use a with statement to make sure the file gets properly closed. Rewriting the above to use a with statement:

import ast

def reading(self):
    with open('deed.txt', 'r') as f:
        s = f.read()
        self.whip = ast.literal_eval(s)

In the most popular Python, known as "CPython", you usually don't need the with statement as the built-in "garbage collection" features will figure out that you are done with the file and will close it for you. But other Python implementations, like "Jython" (Python for the Java VM) or "PyPy" (a really cool experimental system with just-in-time code optimization) might not figure out to close the file for you. It's good to get in the habit of using with, and I think it makes the code pretty easy to understand.

That's because abc is undefined at the moment of the template rendering. You can use safe navigation operator (?) to "protect" template until HTTP call is completed:

{{abc?.xyz?.name}}

You can read more about safe navigation operator here.

Update:

Safe navigation operator can't be used in arrays, you will have to take advantage of NgIf directive to overcome this problem:

<div *ngIf="arr && arr.length > 0">
    {{arr[0].name}}
</div>

Read more about NgIf directive here.

Windows 8 has a notion of a keychain called Password Vault. Windows Runtime apps (Modern/Metro) as well as managed desktop apps can make use of it. According to the documentation:

Apps and services don't have access to credentials associated with other apps or services.

See How to store user credentials on MSDN.

Pre-Windows 8, Data Protection API (DPAPI) is the closest equivalent to a keychain. Arbitrary data can be encrypted using this API, although storing the encrypted data is up to the developer. The data is ultimately encrypted using the current user's password, however user or developer supplied "optional entropy" could be included to further protect the data from other software or users. The data can also be decrypted on different computers in a domain.

DPAPI can be accessed through native calls to Crypt32.dll's CryptProtectData and CryptUnprotectData functions or through .NET Framework's ProtectedData class, which is a limited feature wrapper for the former functions.

More information than you ever needed to know about DPAPI is available in Passcape's article DPAPI Secrets. Security analysis and data recovery in DPAPI.

Just an alternative to the code by rkosegi,

BEGIN

    .. Declare statements ..

    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
    BEGIN
          .. set any flags etc  eg. SET @flag = 0; ..
          ROLLBACK;
    END;

    START TRANSACTION;

        .. Query 1 ..
        .. Query 2 ..
        .. Query 3 ..

    COMMIT;
    .. eg. SET @flag = 1; ..

END

ltrim(strstr($file_url, '.'), '.')

this is the best way if you have filenames like name.name.name.ext (ugly, but it sometimes happens

You could write something like that :

public static bool HasMethod(this object objectToCheck, string methodName)
{
    var type = objectToCheck.GetType();
    return type.GetMethod(methodName) != null;
} 

Edit : you can even do an extension method and use it like this

myObject.HasMethod("SomeMethod");

The MyKey class (@Embeddable) should not have any relationships like @ManyToOne

If you are having an issue with your bin files due to a long path, In Visual Studio 2015 you can go to the offending project's property page and change the relative Output Directory to a shorter one.

E.g. bin\debug\ becomes C:\_bins\MyProject\

Check out the help command:

svn help copy

  -r [--revision] arg      : ARG (some commands also take ARG1:ARG2 range)
                             A revision argument can be one of:
                                NUMBER       revision number
                                '{' DATE '}' revision at start of the date
                                'HEAD'       latest in repository
                                'BASE'       base rev of item's working copy
                                'COMMITTED'  last commit at or before BASE
                                'PREV'       revision just before COMMITTED

To actually specify this on the command line using your example:

svn copy -r123 http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Where 123 would be the revision number in trunk you want to copy. As others have noted, you can also use the @ syntax. I prefer the clearer separation of the revision # from the URL, personally.

As noted in the help, you can replace a revision # with certain words as well:

svn copy -rPREV http://svn.example.com/repos/calc/trunk \
    http://svn.example.com/repos/calc/branches/my-calc-branch

Would copy the "revision just before COMMITTED".

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Within the VM, you can see the mount info /tmp/src on /tmp/src type vboxsf (uid=900,gid=900,rw).

For this and more use cases you can add flowing extension method to your library:

 public static List<DependencyObject> FindAllChildren(this DependencyObject dpo, Predicate<DependencyObject> predicate)
    {
        var results = new List<DependencyObject>();
        if (predicate == null)
            return results;


        for (int i = 0; i < VisualTreeHelper.GetChildrenCount(dpo); i++)
        {
            var child = VisualTreeHelper.GetChild(dpo, i);
            if (predicate(child))
                results.Add(child);

            var subChildren = child.FindAllChildren(predicate);
            results.AddRange(subChildren);
        }
        return results;
    }

Example for your case:

 var children = dpObject.FindAllChildren(child => child is TextBox);

In languages like C curly braces ({}) are used to create program blocks used in flow control. In Python, curly braces are used to define a data structure called a dictionary (a key/value mapping), while white space indentation is used to define program blocks.

The statement from Microsoft regarding the end of Internet Explorer 11 support mentions that it will continue to receive security updates, compatibility fixes, and technical support until its end of life. The wording of this statement leads me to believe that Microsoft has no plans to continue adding features to Internet Explorer 11, and instead will be focusing on Edge.

If you require ES6 features in Internet Explorer 11, check out a transpiler such as Babel.

The question does not contain a nested loop, just a single loop. But THIS nested version works, too:

# for i in c d; do for j in a b; do echo $i $j; done; done
c a
c b
d a
d b

You can simply add DISTINCT in front.

SELECT GROUP_CONCAT(DISTINCT categories SEPARATOR ' ')

if you want to sort,

SELECT GROUP_CONCAT(DISTINCT categories ORDER BY categories ASC SEPARATOR ' ')

Any time you do calculations with doubles, this can happen. This code would give you 877.85:

double answer = Math.round(dCommission * 100000) / 100000.0;

You have to wrap \n or \r in "", not ''. When using single quotes escape sequences will not be interpreted (except \' and \\).

The manual states:

If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:

• \n linefeed (LF or 0x0A (10) in ASCII)

• \r carriage return (CR or 0x0D (13) in ASCII)\

• (...)

One way would be store the current colour for each row within the model. Here's a simple model that is fixed at 3 columns and 3 rows:

static class MyTableModel extends DefaultTableModel {

    List<Color> rowColours = Arrays.asList(
        Color.RED,
        Color.GREEN,
        Color.CYAN
    );

    public void setRowColour(int row, Color c) {
        rowColours.set(row, c);
        fireTableRowsUpdated(row, row);
    }

    public Color getRowColour(int row) {
        return rowColours.get(row);
    }

    @Override
    public int getRowCount() {
        return 3;
    }

    @Override
    public int getColumnCount() {
        return 3;
    }

    @Override
    public Object getValueAt(int row, int column) {
        return String.format("%d %d", row, column);
    }
}

Note that setRowColour calls fireTableRowsUpdated; this will cause just that row of the table to be updated.

The renderer can get the model from the table:

static class MyTableCellRenderer extends DefaultTableCellRenderer {

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {
        MyTableModel model = (MyTableModel) table.getModel();
        Component c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        c.setBackground(model.getRowColour(row));
        return c;
    }
}

Changing a row's colour would be as simple as:

model.setRowColour(1, Color.YELLOW);

For starters, all ChromeDriver versions are not compatible with all versions of Chrome.

Have a look at the example in this link :

http://docs.angularjs.org/api/ngSanitize.$sanitize

Basically, angular has a directive to insert html into pages. In your case you can insert the html using the ng-bind-html directive like so :

If you already have done all this :

// My magic HTML string function.
function htmlString (str) {
    return "<h1>" + str + "</h1>";
}

function Ctrl ($scope) {
  var str = "HELLO!";
  $scope.htmlString = htmlString(str);
}
Ctrl.$inject = ["$scope"];

Then in your html within the scope of that controller, you could

<div ng-bind-html="htmlString"></div>

for example:

dir1=$(find . -name \*foo\* -type d -maxdepth 1 -print | head -n1)
echo "$dir1"

or (For the better shell solution see Adrian Frühwirth's answer)

for dir1 in *
do
    [[ -d "$dir1" && "$dir1" =~ foo ]] && break
    dir1=        #fix based on comment
done
echo "$dir1"

or

dir1=$(find . -type d -maxdepth 1 -print | grep 'foo' | head -n1)
echo "$dir1"

Edited head -n1 based on @ hek2mgl comment

Next based on @chepner's comments

dir1=$(find . -type d -maxdepth 1 -print | grep -m1 'foo')

or

dir1=$(find . -name \*foo\* -type d -maxdepth 1 -print -quit)

There are quite lots of answer based on situation.

1) Try to replace '$' with "jQuery"

2) Check that code you are executed are always below the main jquery script.

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<script type="text/javascript">
jQuery(document).ready(function(){

});
</script>

3) Pass $ into the function and add "jQuery" as a main function like below.

<script type="text/javascript">
jQuery(document).ready(function($){

});
</script>

In case anyone is wondering what input value

<input (keydown.enter)="search($event.target.value)" />

If you really want the runtime type to be util.Date then just do this:

java.util.Date utilDate = new java.util.Date(sqlDate.getTime());

How about

mydatagrid.UpdateLayout();

I've solved this issue adding user and password in Transport.send call:

Transport.send(msg, "user", "password");

According to this signature of the send function in javax.mail (from version 1.5):

public static void send(Message msg, String user, String password)

Also, if you use this signature it's not necessary to set up any Authenticator, and to set user and password in the Properties (only the host is needed). So your code could be:

private void sendMail(){
  try{
      Properties prop = System.getProperties();
      prop.put("mail.smtp.host", "yourHost");
      Session session = Session.getInstance(prop);
      Message msg = #createYourMsg(session, from, to, subject, mailer, yatta yatta...)#;
      Transport.send(msg, "user", "password");
  }catch(Exception exc) {
      // Deal with it! :)
  }
}

                result.append(element)
            }
        }

}

maybe this will help you (if the log file exists use it, if it does not exist create it):

package main

    "flag"
    "log"
    "os"
)
//Se declara la variable Log. Esta será usada para registrar los eventos.
var (
    Log *log.Logger = Loggerx()
)

func Loggerx() *log.Logger {
    LOG_FILE_LOCATION := os.Getenv("LOG_FILE_LOCATION")
        //En el caso que la variable de entorno exista, el sistema usa la configuración del docker.
    if LOG_FILE_LOCATION == "" {
        LOG_FILE_LOCATION = "../logs/" + APP_NAME + ".log"
    } else {
        LOG_FILE_LOCATION = LOG_FILE_LOCATION + APP_NAME + ".log"
    }
    flag.Parse()
        //Si el archivo existe se rehusa, es decir, no elimina el archivo log y crea uno nuevo.
    if _, err := os.Stat(LOG_FILE_LOCATION); os.IsNotExist(err) {
        file, err1 := os.Create(LOG_FILE_LOCATION)
        if err1 != nil {
            panic(err1)
        }
                //si no existe,se crea uno nuevo.
        return log.New(file, "", log.Ldate|log.Ltime|log.Lshortfile)
    } else {
                //si existe se rehusa.
        file, err := os.OpenFile(LOG_FILE_LOCATION, os.O_CREATE|os.O_APPEND|os.O_WRONLY, 0666)
        if err != nil {
            panic(err)
        }
        return log.New(file, "", log.Ldate|log.Ltime|log.Lshortfile)

The data-role="none" is the key to make them work together. You can apply to the elements you want bootstrap to touch but jquery mobile to ignore. like this input type="text" class="form-control" placeholder="Search" data-role="none"

Execute this at the terminal to see conflicting configurations listening to the same port:

grep -R default_server /etc/nginx

Since Ruby 2.5.0, Array ships with the prepend method (which is just an alias for the unshift method).

DataReader:

• Holds the connection open until you are finished (don't forget to close it!).
• Can typically only be iterated over once
• Is not as useful for updating back to the database

On the other hand, it:

• Only has one record in memory at a time rather than an entire result set (this can be HUGE)
• Is about as fast as you can get for that one iteration
• Allows you start processing results sooner (once the first record is available). For some query types this can also be a very big deal.

DataAdapter/DataSet

• Lets you close the connection as soon it's done loading data, and may even close it for you automatically
• All of the results are available in memory
• You can iterate over it as many times as you need, or even look up a specific record by index
• Has some built-in faculties for updating back to the database

At the cost of:

• Much higher memory use
• You wait until all the data is loaded before using any of it

So really it depends on what you're doing, but I tend to prefer a DataReader until I need something that's only supported by a dataset. SqlDataReader is perfect for the common data access case of binding to a read-only grid.

For more info, see the official Microsoft documentation.

This will give you sequence of anonymous objects, containing date string and two properties with average price:

var query = from p in PriceLogList
            group p by p.LogDateTime.ToString("MMM yyyy") into g
            select new { 
               LogDate = g.Key,
               AvgGoldPrice = (int)g.Average(x => x.GoldPrice), 
               AvgSilverPrice = (int)g.Average(x => x.SilverPrice)
            };

If you need to get list of PriceLog objects:

var query = from p in PriceLogList
            group p by p.LogDateTime.ToString("MMM yyyy") into g
            select new PriceLog { 
               LogDateTime = DateTime.Parse(g.Key),
               GoldPrice = (int)g.Average(x => x.GoldPrice), 
               SilverPrice = (int)g.Average(x => x.SilverPrice)
            };

The easiest is setting a program variable (see GDB: assignment):

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

Or you can just update arbitrary (writable) location by address:

(gdb) set {int}0x83040 = 4

There's more. Read the manual.

The best thing to do is to use the algorithm remove_if and isspace:

remove_if(str.begin(), str.end(), isspace);

Now the algorithm itself can't change the container(only modify the values), so it actually shuffles the values around and returns a pointer to where the end now should be. So we have to call string::erase to actually modify the length of the container:

str.erase(remove_if(str.begin(), str.end(), isspace), str.end());

We should also note that remove_if will make at most one copy of the data. Here is a sample implementation:

template<typename T, typename P>
T remove_if(T beg, T end, P pred)
{
    T dest = beg;
    for (T itr = beg;itr != end; ++itr)
        if (!pred(*itr))
            *(dest++) = *itr;
    return dest;
}

Very simply:

$id = substr($url, strrpos($url, '/') + 1);

strrpos gets the position of the last occurrence of the slash; substr returns everything after that position.

As mentioned by redanimalwar if there is no slash this doesn't work correctly since strrpos returns false. Here's a more robust version:

$pos = strrpos($url, '/');
$id = $pos === false ? $url : substr($url, $pos + 1);

I prefer the for loop as it's more readable. Looping from length to 0 would be more efficient than looping from 0 to length. And using a reversed while loop is more efficient than a foor loop as you said. I don't have the link to the page with comparison results anymore but I remember that the difference varied on different browsers. For some browser the reversed while loop was twice as fast. However it makes no difference if you're looping "small" arrays. In your example case the length of elements will be "small"

You would expect that this is easily possible but that seems not be the case. The only way I see at the moment is to create a user defined JQL function. I never tried this but here is a plug-in:

http://confluence.atlassian.com/display/DEVNET/Plugin+Tutorial+-+Adding+a+JQL+Function+to+JIRA

You cannot.

However, you may want to have a look at one of my projects which allows you to more easily manipulate such "throwing lambdas".

In your case, you would be able to do that:

import static com.github.fge.lambdas.functions.Functions.wrap;

final ThrowingFunction<String, Class<?>> f = wrap(Class::forName);

List<Class> classes =
    Stream.of("java.lang.Object", "java.lang.Integer", "java.lang.String")
          .map(f.orThrow(MyException.class))
          .collect(Collectors.toList());

and catch MyException.

That is one example. Another example is that you could .orReturn() some default value.

Note that this is STILL a work in progress, more is to come. Better names, more features etc.

I made a library called manual-promise that functions as a drop in replacement for Promise. None of the other answers here will work as drop in replacements for Promise, as they use proxies or wrappers.

yarn add manual-promise

npn install manual-promise

import { ManualPromise } from "manual-promise";

const prom = new ManualPromise();

prom.resolve(2);

// actions can still be run inside the promise
const prom2 = new ManualPromise((resolve, reject) => {
    // ... code
});


new ManualPromise() instanceof Promise === true

Create new classes to overwrite the width. See jFiddle for working code.

<div class="row">
  <div class="col-xs-1 col-xs-1-5">
    <div class="box">
      box 1
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 2
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 3
    </div>
  </div>
  <div class="col-xs-3 col-xs-3-5">
    <div class="box">
      box 4
    </div>
  </div>
</div>

.col-xs-1-5 {
  width: 12.49995%;
}
.col-xs-3-5 {
  width: 29.16655%;
}
.box {
  border: 1px solid #000;
  text-align: center;
}

It just exits the method at that point. Once return is executed, the rest of the code won't be executed.

eg.

public void test(int n) {
    if (n == 1) {
        return; 
    }
    else if (n == 2) {
        doStuff();
        return;
    }
    doOtherStuff();
}

Note that the compiler is smart enough to tell you some code cannot be reached:

if (n == 3) {
    return;
    youWillGetAnError(); //compiler error here
}

Simple solution:

document.onpaste = function(e) {
    var pasted = e.clipboardData.getData('Text');
    console.log(pasted)
}

Conda can also be used as package manager. It can be installed from Anaconda.

Alternatively, a free minimal installer is Miniconda.

We use Array.from({length: 500}) since 2017.

Just for fun, here's my completed solution for getting PYTHON output - under a button click - with error reporting. Just add a button called "butPython" and a label called "llHello"...

    private void butPython(object sender, EventArgs e)
    {
        llHello.Text = "Calling Python...";
        this.Refresh();
        Tuple<String,String> python = GoPython(@"C:\Users\BLAH\Desktop\Code\Python\BLAH.py");
        llHello.Text = python.Item1; // Show result.
        if (python.Item2.Length > 0) MessageBox.Show("Sorry, there was an error:" + Environment.NewLine + python.Item2);
    }

    public Tuple<String,String> GoPython(string pythonFile, string moreArgs = "")
    {
        ProcessStartInfo PSI = new ProcessStartInfo();
        PSI.FileName = "py.exe";
        PSI.Arguments = string.Format("\"{0}\" {1}", pythonFile, moreArgs);
        PSI.CreateNoWindow = true;
        PSI.UseShellExecute = false;
        PSI.RedirectStandardError = true;
        PSI.RedirectStandardOutput = true;
        using (Process process = Process.Start(PSI))
            using (StreamReader reader = process.StandardOutput)
            {
                string stderr = process.StandardError.ReadToEnd(); // Error(s)!!
                string result = reader.ReadToEnd(); // What we want.
                return new Tuple<String,String> (result,stderr); 
            }
    }

I don't know of a way to force Chrome to not clear the Network debugger, but this might accomplish what you're looking for:

1. Open the js console
2. window.addEventListener("beforeunload", function() { debugger; }, false)

This will pause chrome before loading the new page by hitting a breakpoint.

I have discovered that NotePad++ now also creates a subfolder at the file location, called nppBackup. So if your file lived in a folder called c:/thisfolder have a look to see if there's a folder called c:/thisfolder/nppBackup.

Occasionally I couldn't find the backup in AppData\Roaming\Notepad++\backup, but I found it in nppBackup.

I've used this tool before- although it seems like there needs to be an issue open first, it is super useful and really streamlines workflow if you use github issue tracking. git open-pull and then a pull request is submitted from whatever branch you are on or select. https://github.com/jehiah/git-open-pull

EDIT: Looks like you can create issues on the fly, so this tool is a good solution.

Actually, the Sysinternals junction command only works with directories (don't ask me why), so it can't hardlink files. I would go with cmd /c mklink for soft links (I can't figure why it's not supported directly by PowerShell), or fsutil for hardlinks.

If you need it to work on Windows XP, I do not know of anything other than Sysinternals junction, so you might be limited to directories.

I guess it's just because the onblur event is called as a result of the input losing focus, there isn't a blur action associated with an input, like there is a click action associated with a button

I need to do this and have the <dt> content vertically centered, relative to the <dd> content. I used display: inline-block, together with vertical-align: middle

See full example on Codepen here

.dl-horizontal {
  font-size: 0;
  text-align: center;

  dt, dd {
    font-size: 16px;
    display: inline-block;
    vertical-align: middle;
    width: calc(50% - 10px);
  }

  dt {
    text-align: right;
    padding-right: 10px;
  }

  dd {
    font-size: 18px;
    text-align: left;
    padding-left: 10px;
  } 
}

It's close! Try this:

for (var prop in result) {
    if (result.hasOwnProperty(prop)) {
        alert(result[prop]);
    }
}

Update:

If your result is truly is an array of one object, then you might have to do this:

for (var prop in result[0]) {
    if (result[0].hasOwnProperty(prop)) {
        alert(result[0][prop]);
    }
}

Or if you want to loop through each result in the array if there are more, try:

for (var i = 0; i < results.length; i++) {
    for (var prop in result[i]) {
        if (result[i].hasOwnProperty(prop)) {
            alert(result[i][prop]);
        }
    }
}

A much better way is to use inline-block, because you don't need to use clear:both at the end of your list anymore.

Try this:

<ul>
    <li>
        <a href="#">some item</a>
    </li>
    <li>
        <a href="#">another item</a>
    </li>
</ul>

CSS:

ul > li{
    display:inline-block;
}

Have a look at it here : http://jsfiddle.net/shahverdy/4N6Ap/

In my case I did not need to close the whole VS-Code, closing the opened file (and sometimes even saving it) solved the issue.

start the sql server agent, that should fix your problem

For a div-Element you could just set the opacity via a class to enable or disable the effect.

.mute-all {
   opacity: 0.4;
}

public JSONObject makJsonObject(int id[], String name[], String year[],
            String curriculum[], String birthday[], int numberof_students)
            throws JSONException {
        JSONObject obj = null;
        JSONArray jsonArray = new JSONArray();
        for (int i = 0; i < numberof_students; i++) {
            obj = new JSONObject();
            try {
                obj.put("id", id[i]);
                obj.put("name", name[i]);
                obj.put("year", year[i]);
                obj.put("curriculum", curriculum[i]);
                obj.put("birthday", birthday[i]);

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            jsonArray.put(obj);
        }

        JSONObject finalobject = new JSONObject();
        finalobject.put("student", jsonArray);
        return finalobject;
    }

If you want to enable general error logs and slow query error log in the table instead of file

To start logging in table instead of file:

set global log_output = “TABLE”;

To enable general and slow query log:

set global general_log = 1;
set global slow_query_log = 1;

To view the logs:

select * from mysql.slow_log;
select * from mysql.general_log;

Using jQuery

I would create a button and an invisible input like so:

<button id="button">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

and add some jQuery to trigger it:

$('#button').on('click', function() {
    $('#file-input').trigger('click');
});

Using Vanilla JS

Same idea, without jQuery (credits to @Pascale):

<button onclick="document.getElementById('file-input').click();">Open</button>
<input id="file-input" type="file" name="name" style="display: none;" />

You can do it with window functions

SELECT t.*
FROM
    (SELECT
        *,
        ROW_NUMBER() OVER(PARTITION BY usr_id ORDER BY time_stamp DESC) as r
    FROM lives) as t
WHERE t.r = 1

You can use OutputDebugString. OutputDebugString is a macro that depending on your build options either maps to OutputDebugStringA(char const*) or OutputDebugStringW(wchar_t const*). In the later case you will have to supply a wide character string to the function. To create a wide character literal you can use the L prefix:

OutputDebugStringW(L"My output string.");

Normally you will use the macro version together with the _T macro like this:

OutputDebugString(_T("My output string."));

If you project is configured to build for UNICODE it will expand into:

OutputDebugStringW(L"My output string.");

If you are not building for UNICODE it will expand into:

OutputDebugStringA("My output string.");

I you want to put the response of the request in the navItems. Because http.get() return an observable you will have to subscribe to it.

Look at this example:

// version without map_x000D_
this.http.get("../data/navItems.json")_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success.json();          _x000D_
    });_x000D_
_x000D_
// with map_x000D_
import 'rxjs/add/operator/map'_x000D_
this.http.get("../data/navItems.json")_x000D_
    .map((data) => {_x000D_
      return data.json();_x000D_
    })_x000D_
    .subscribe((success) => {_x000D_
      this.navItems = success;          _x000D_
    });

In the default constructor (and any non-default ones if you have any too of course):

public foo() {
    Bar = "bar";
}

This is no less performant that your original code I believe, since this is what happens behind the scenes anyway.

The excellent joda-time library is almost always a better choice than Java's Date or Calendar classes. Here's a few examples:

DateTime aDate = new DateTime(year, month, day, hour, minute, second);
DateTime anotherDate = new DateTime(anotherYear, anotherMonth, anotherDay, ...);
if (aDate.isAfter(anotherDate)) {...}
DateTime yearFromADate = aDate.plusYears(1);

In general, that's not how systems use GET requests. So, it will be hard to get your libraries to play along. In fact, the spec says that "If the request method is a case-sensitive match for GET or HEAD act as if data is null." So, I think you are out of luck unless the browser you are using doesn't respect that part of the spec.

You can probably setup an endpoint on your own server for a POST ajax request, then redirect that in your server code to a GET request with a body.

If you aren't absolutely tied to GET requests with the body being the data, you have two options.

POST with data: This is probably what you want. If you are passing data along, that probably means you are modifying some model or performing some action on the server. These types of actions are typically done with POST requests.

GET with query string data: You can convert your data to query string parameters and pass them along to the server that way.

This is what I came up to when trying to copy-paste excel ranges with it's sizes and cell groups. It might be a little too specific for my problem but...:

The easiest way is to define a class let's call it Namespace. which uses the object dict.update() on the dict. Then, the dict will be treated as an object.

class Namespace(object):
    '''
    helps referencing object in a dictionary as dict.key instead of dict['key']
    '''
    def __init__(self, adict):
        self.__dict__.update(adict)



Person = Namespace({'name': 'ahmed',
                     'age': 30}) #--> added for edge_cls


print(Person.name)

Crude but working way will be to force the scroll back to top, thus effectively disabling scrolling:

var _stopScroll = false;
window.onload = function(event) {
    document.onscroll = function(ev) {
        if (_stopScroll) {
            document.body.scrollTop = "0px";
        }
    }
};

When you open the lightbox raise the flag and when closing it,lower the flag.

Live test case.

To check for null values you could use _.isNull from official documentation

isNull_.isNull(object)

Returns true if the value of object is null.

_.isNull(null);
=> true
_.isNull(undefined);
=> false

My Solution

User.find()
        .exec()
        .then(users => {
            const response = {
                count: users.length,
                users: users.map(user => {

                    return {
                        _id: user._id,
                        // other property
                    }

                })

            };
            res.status(200).json(response);
        }).catch(err => {
        console.log(err);
        res.status(500).json({
            success: false
        })
    })

In 2019, it will automatically open a new session, new instance of vs-code. By type

      C:\Apache24\htdocs\json2tree>code .

at the command window, under your project root folder.

first cd into your project folder,

        C:\Apache24\htdocs\json2tree>

then, type

         code .

Or maybe even easier

grep -R put **/*bills*

The ** glob syntax means "any depth of directories". It will work in Zsh, and I think recent versions of Bash too.

Schema is a way of categorising the objects in a database. It can be useful if you have several applications share a single database and while there is some common set of data that all application accesses.

this worked for me:

ProxyRequests     Off
ProxyPreserveHost On
RewriteEngine On

<Proxy http://localhost:8123>
Order deny,allow
Allow from all
</Proxy>

ProxyPass         /node  http://localhost:8123  
ProxyPassReverse  /node  http://localhost:8123

Creating an isolate scope is undesirable. I would avoid using the scope attribute and do something like this. scope:true gives you a new child scope but not isolate. Then use parse to point a local scope variable to the same object the user has supplied to the ngModel attribute.

app.directive('myDir', ['$parse', function ($parse) {
    return {
        restrict: 'EA',
        scope: true,
        link: function (scope, elem, attrs) {
            if(!attrs.ngModel) {return;}
            var model = $parse(attrs.ngModel);
            scope.model = model(scope);
        }
    };
}]);

Get-Content (alias: gc) is your usual option for reading a text file. You can then filter further:

gc log.txt | select -first 10 # head
gc -TotalCount 10 log.txt     # also head
gc log.txt | select -last 10  # tail
gc -Tail 10 log.txt           # also tail (since PSv3), also much faster than above option
gc log.txt | more             # or less if you have it installed
gc log.txt | %{ $_ -replace '\d+', '($0)' }         # sed

This works well enough for small files, larger ones (more than a few MiB) are probably a bit slow.

The PowerShell Community Extensions include some cmdlets for specialised file stuff (e.g. Get-FileTail).

is there a possibility that casting a double created via Math.round() will still result in a truncated down number

No, round() will always round your double to the correct value, and then, it will be cast to an long which will truncate any decimal places. But after rounding, there will not be any fractional parts remaining.

Here are the docs from Math.round(double):

Returns the closest long to the argument. The result is rounded to an integer by adding 1/2, taking the floor of the result, and casting the result to type long. In other words, the result is equal to the value of the expression:

(long)Math.floor(a + 0.5d)

Yes! It is possible

Long approach but you can get all the data's using just .frm files. Of course you need other files in the mysql/data directory.

My Problem

One day my harddisk crashed and got the booting blue screen error. I try connecting with multiple machine and it didn't work. Since it is a booting error i was concered about the files. and i tryed with the secondary harddisk and try to recover the folders and files. I also backed up the full xampp folder c:/xampp just in case, Because I had no back of the recent databases i got really worried how to retrieve the database. we have lot of clients project management and personal doc in the database.

None of the method listed on the stackoverflow comment works, at-least for me. It took me 2 full days googling for the answer to get the data's from the .frm files. Came across multiple approaches from many people but everything was frustration and getting some error or another when implementing. If most of them get it working (based on their comment) then what am i missing.

Because i was so desperate I even reinstall windows which result in loosing all my softwares and tried again. But still the same error

THANKS to Dustin Davis

i found the solution in his blog and i managed to get it working exactly the same way he did. Let me give the credit to this guy, Dustin Davis (https://dustindavis.me/restoring-mysql-innodb-files-on-windows/). You could jump from here to his blog and try his method, pretty clear and easy to follow.

But there are something i discovered when trying his approach which he hasn't explained in his blog and i will try my best to explain how i did and what you need to look for.

Follow this exactly

IMPORTANT: Make sure you to install the same version of XAMPP. You cannot copy paste from older XAMPP to a new version. This will result in __config or __tracking errors.

How to check your XAMPP version

1. Go to your xampp folder (your backed up xampp).
2. Open the readme_en.txt file. which is in the root directory of the xampp.
3. You should see the version on top. ###### ApacheFriends XAMPP Version X.X.XX ######

Files require to restore

xampp(old folder)/mysql/data/

ibdata1
ib_logfile0
ib_logfile1
<databasename>/*.frm
<databasename>/*.ibd

Step 1

1. After installed the same version of xampp.
2. Do not start the apache or myql

Step 2

• Go to the mysql/data folder and replace the ibdata1, ib_logfile0, and ib_logfile1
• Now copy paste your database folder from your old xampp backup to the newly installed xampp folder c:/xampp/mysql/data/ that contain .frm and .ibd files, If you are not sure try with one database.

Step 3

• Go to c:/xampp/mysql/bin and look for my.cn.
• Open the my.cn file and look for #skip-innodb and under that look for the line that says innodb_log_file_size=5M change it to 170M. innodb_log_file_size=170M. This is your log file size and if you are not sure just set it to 170

Step 4

• Now open the file mysql_start.bat (Windows Batch file) that is in the c:/xampp/ directory.

• Add –innodb_force_recovery=6 after the ... --console

  ....
  
  mysql\bin\mysqld --defaults-file=mysql\bin\my.ini --standalone --console
  –innodb_force_recovery=6
  if errorlevel 1 goto error
  goto finish
  

Step 5

• Now Start your Apache and Mysql.
• Go to your phpmyadmin and check for your database and its tables. if you do not get any errors you are on the right track.
• Stop the Apache and Mysql and copy paste the rest of the databases.

I had this same issue. I realized that it was because I was using xcode while I was using it. Since the updates didn't install correctly, it caused these errors to show up. The only thing that fixed it was to quit xcode and reopen it. When I reopened it, it prompted me to install updates. After the updates were installed, the errors went away.

Why not use a library function to validate the ip address?

>>> ip="241.1.1.112343434" 
>>> socket.inet_aton(ip)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.error: illegal IP address string passed to inet_aton

Try putting your text in another div inside your span:

i.e.

<span><div>some text</div></span>

In order to find a 'word', rather than the occurrence of a series of letters that could in fact be a part of another word, the following would be a good solution.

$string = 'How are you?';
$array = explode(" ", $string);

if (in_array('are', $array) ) {
    echo 'Found the word';
}

Use Glib::ustring from glibmm.

It is the only widespread UTF-8 string container (AFAIK). While glyph (not byte) based, it has the same method signatures as std::string so the port should be simple search and replace (just make sure that your data is valid UTF-8 before loading it into a ustring).

Not a single answer mentions String.localeCompare, which happens to do exactly what you originally wanted, but not what you're asking for.

var list = ['a', 'b', 'c', 'o', 'u', 'z', 'ä', 'ö', 'ü'];

list.sort((a, b) => a.localeCompare(b));

console.log(list);

//Outputs ['a', 'ä', 'b', 'c', 'o', 'ö', 'u', 'ü', 'z']

The second and third parameter are not supported by older browsers though. It's an option worth considering nonetheless.

You never give any value to your strings in main so they are empty, and thus obviously the function returns an empty string.

Replace:

string str1, str2, str3;

with:

string str1 = "the dog jumped over the fence";
string str2 = "the";
string str3 = "that";

Also, you have several problems in your replaceSubstring function:

int index = s1.find(s2, 0);
s1.replace(index, s2.length(), s3);

• std::string::find returns a std::string::size_type (aka. size_t) not an int. Two differences: size_t is unsigned, and it's not necessarily the same size as an int depending on your platform (eg. on 64 bits Linux or Windows size_t is unsigned 64 bits while int is signed 32 bits).
• What happens if s2 is not part of s1? I'll leave it up to you to find how to fix that. Hint: std::string::npos ;)

doAnswer and thenReturn do the same thing if:

1. You are using Mock, not Spy
2. The method you're stubbing is returning a value, not a void method.

Let's mock this BookService

public interface BookService {
    String getAuthor();
    void queryBookTitle(BookServiceCallback callback);
}

You can stub getAuthor() using doAnswer and thenReturn.

BookService service = mock(BookService.class);
when(service.getAuthor()).thenReturn("Joshua");
// or..
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        return "Joshua";
    }
}).when(service).getAuthor();

Note that when using doAnswer, you can't pass a method on when.

// Will throw UnfinishedStubbingException
doAnswer(invocation -> "Joshua").when(service.getAuthor());

So, when would you use doAnswer instead of thenReturn? I can think of two use cases:

1. When you want to "stub" void method.

Using doAnswer you can do some additionals actions upon method invocation. For example, trigger a callback on queryBookTitle.

BookServiceCallback callback = new BookServiceCallback() {
    @Override
    public void onSuccess(String bookTitle) {
        assertEquals("Effective Java", bookTitle);
    }
};
doAnswer(new Answer() {
    @Override
    public Object answer(InvocationOnMock invocation) throws Throwable {
        BookServiceCallback callback = (BookServiceCallback) invocation.getArguments()[0];
        callback.onSuccess("Effective Java");
        // return null because queryBookTitle is void
        return null;
    }
}).when(service).queryBookTitle(callback);
service.queryBookTitle(callback);

2. When you are using Spy instead of Mock

When using when-thenReturn on Spy Mockito will call real method and then stub your answer. This can cause a problem if you don't want to call real method, like in this sample:

List list = new LinkedList();
List spy = spy(list);
// Will throw java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
when(spy.get(0)).thenReturn("java");
assertEquals("java", spy.get(0));

Using doAnswer we can stub it safely.

List list = new LinkedList();
List spy = spy(list);
doAnswer(invocation -> "java").when(spy).get(0);
assertEquals("java", spy.get(0));

Actually, if you don't want to do additional actions upon method invocation, you can just use doReturn.

List list = new LinkedList();
List spy = spy(list);
doReturn("java").when(spy).get(0);
assertEquals("java", spy.get(0));

JSmooth .exe wrapper

JSmooth is a Java Executable Wrapper. It creates native Windows launchers (standard .exe) for your Java applications. It makes java deployment much smoother and user-friendly, as it is able to find any installed Java VM by itself. When no VM is available, the wrapper can automatically download and install a suitable JVM, or simply display a message or redirect the user to a website.

JSmooth provides a variety of wrappers for your java application, each of them having their own behavior: Choose your flavor!

JarToExe 1.8 Jar2Exe is a tool to convert jar files into exe files. Following are the main features as describe on their website:

Can generate “Console”, “Windows GUI”, “Windows Service” three types of .exe files.

Generated .exe files can add program icons and version information. Generated .exe files can encrypt and protect java programs, no temporary files will be generated when the program runs.

Generated .exe files provide system tray icon support. Generated .exe files provide record system event log support. Generated windows service .exe files are able to install/uninstall itself, and support service pause/continue.

• New release of x64 version, can create 64 bits executives. (May 18, 2008)
• Both wizard mode and command line mode supported. (May 18, 2008)

Executor

Package your Java application as a jar, and Executor will turn the jar into a Windows .exe file, indistinguishable from a native application. Simply double-clicking the .exe file will invoke the Java Runtime Environment and launch your application.

For iOS 13

As from iOS 13 your app also needs Core Location access in order to use the CNCopyCurrentNetworkInfo function unless it configured the current network or has VPN configurations:

So this is what you need (see apple documentation):
- Link the CoreLocation.framework library
- Add location-services as a UIRequiredDeviceCapabilities Key/Value in Info.plist
- Add a NSLocationWhenInUseUsageDescription Key/Value in Info.plist describing why your app requires Core Location
- Add the "Access WiFi Information" entitlement for your app

Now as an Objective-C example, first check if location access has been accepted before reading the network info using CNCopyCurrentNetworkInfo:

- (void)fetchSSIDInfo {
    NSString *ssid = NSLocalizedString(@"not_found", nil);

    if (@available(iOS 13.0, *)) {
        if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusDenied) {
            NSLog(@"User has explicitly denied authorization for this application, or location services are disabled in Settings.");
        } else {
            CLLocationManager* cllocation = [[CLLocationManager alloc] init];
            if(![CLLocationManager locationServicesEnabled] || [CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined){
                [cllocation requestWhenInUseAuthorization];
                usleep(500);
                return [self fetchSSIDInfo];
            }
        }
    }

    NSArray *ifs = (__bridge_transfer id)CNCopySupportedInterfaces();
    id info = nil;
    for (NSString *ifnam in ifs) {
        info = (__bridge_transfer id)CNCopyCurrentNetworkInfo(
            (__bridge CFStringRef)ifnam);

        NSDictionary *infoDict = (NSDictionary *)info;
        for (NSString *key in infoDict.allKeys) {
            if ([key isEqualToString:@"SSID"]) {
                ssid = [infoDict objectForKey:key];
            }
        }
    }        
        ...
    ...
}

There are a million duplicates of this question on here, but here goes again anyway:

document.onkeypress = function(evt) {
    evt = evt || window.event;
    var charCode = evt.keyCode || evt.which;
    var charStr = String.fromCharCode(charCode);
    alert(charStr);
};

The best reference on key events I've seen is http://unixpapa.com/js/key.html.

Well, it doesn't get much better than that. Officially, you should use

dataGridView1.DataSource = typeof(List); 
dataGridView1.DataSource = itemStates;

It's still a "clear/reset source" kind of solution, but I have yet to find anything else that would reliably refresh the DGV data source.
