No problem. You're running your code under the debugger, and the debugger is telling you that it doesn't have debugging information for the system libraries.

If you really need that (usually for stack traces), you can download it from Microsoft's symbol servers, but for now you don't need to worry.

Get number of threads using jstack

jstack <PID> | grep 'java.lang.Thread.State' | wc -l

The result of the above code is quite different from top -H -p <PID> or ps -o nlwp <PID> because jstack gets only threads from created by the application.

In other words, jstack will not get GC threads

TCP guarantees packet delivery AND order. Order is almost as important as the delivery in the first place when reconstructing data for files such as executables, etc.

UDP does not guarantee delivery NOR order. Packets can arrive (or not!) in any order.

Common uses for TCP include file transfer where the integrity of the packets is paramount. Voice/video applications can afford to lose some data while still maintaining acceptable quality, and so usually use UDP.

What you want is to load the data again but not reload the div.

You need to make an Ajax query to get data from the server and fill the DIV.

Assuming the iFrame has a name attribute of "myIframe":

<a href="http://www.google.com" target="myIframe">Link Text</a> 

You can also accomplish this with the use of Javascript. The iFrame has a src attribute which specifies the location it shows. As such, it's a simple matter of binding the click of a link to changing that src attribute.

TL;DR. In Visual Studio 2019, when you add an Icon resource to a Win32 (desktop) application you get an auto-generated icon file that has the formats below. I assume that the #1 developer tool for Windows does this right. Thus, a Windows compatible should have the following formats:

| Resolution | Color depth | Format |
|:-----------|------------:|:------:|
| 256x256    |      32-bit |  PNG   |
| 64x64      |      32-bit |  BMP   |
| 48x48      |      32-bit |  BMP   |
| 32x32      |      32-bit |  BMP   |
| 16x16      |      32-bit |  BMP   |
| 48x48      |       8-bit |  BMP   |
| 32x32      |       8-bit |  BMP   |
| 16x16      |       8-bit |  BMP   |

JConsole has a graphical view.

You also have VisualVM and Oracle JRockit Mission Control

You can use event.preventDefault() to avoid this. Read more here: http://api.jquery.com/event.preventDefault/.

I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..

Opening A Seperate File:

ChDir "[Path here]"                          'get into the right folder here
Workbooks.Open Filename:= "[Path here]"      'include the filename in this path

'copy data into current workbook or whatever you want here

ActiveWindow.Close                          'closes out the file

Opening A File With Specified Date If It Exists:

I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.

Some common error checking statements:

On Error Resume Next   'if error occurs continues on to the next line (ignores it)

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

Or (better option):

if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?

you would most likely want to use the GoTo ErrorHandler shown below to achieve this

On Error GoTo ErrorHandler:

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

ErrorHandler:
'Display error message or any code you want to run on error here

Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm

Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/

Hope this helps!

Example on how to ensure error code doesn't run EVERYtime:

if you debug through the code without the Exit Sub BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.

  Sub Macro

    On Error GoTo ErrorHandler:

    ChDir "[Path here]"                         
    Workbooks.Open Filename:= "[Path here]"      'try to open file here

    Exit Sub      'Code will exit BEFORE ErrorHandler if everything goes smoothly
                  'Otherwise, on error, ErrorHandler will be run

    ErrorHandler:
    'Display error message or any code you want to run on error here

  End Sub

Also, look at this other question in you need more reference to how this works: goto block not working VBA

You can use the following snippet to delete unavailable runtimes:

echo "rm -rf $(xcrun simctl list runtimes -j |\
      jq ".runtimes[] | select(.isAvailable|not) | .bundlePath" | xargs)"

to execute, remove echo or add | bash at the end.

If you don't have jq command available, you can get it using brew install jq

I let the CI server pipe the following into a file named CHANGELOG for a each new release with the date set in the release-filename:

>git log --graph --all --date=relative --pretty=format:"%x09 %ad %d %s (%aN)"

Without VBA macro, you can use this tips to get the username from the path :

=MID(INFO("DIRECTORY"),10,LEN(INFO("DIRECTORY"))-LEN(MID(INFO("DIRECTORY"),FIND("\",INFO("DIRECTORY"),10),1000))-LEN("C:\Users\"))

Do you merely want to print the string that way, or do you want that to be the internal representation of the string? If the latter, create it as a raw string by prefixing it with r: r"Hello\tWorld\nHello World".

>>> a = r"Hello\tWorld\nHello World"
>>> a # in the interpreter, this calls repr()
'Hello\\tWorld\\nHello World'
>>> print a
Hello\tWorld\nHello World

Also, \s is not an escape character, except in regular expressions, and then it still has a much different meaning than what you're using it for.

I think you should make a subquery to do grouping. In this case inner subquery returns few rows and you don't need a CASE statement. So I think this is going to be faster:

select Detail.ReceiptDate AS 'DATE',
       SUM(TotalMailed),
       SUM(TotalReturnMail),
       SUM(TraceReturnedMail)

from
(

select SentDate AS 'ReceiptDate', 
       count('TotalMailed') AS TotalMailed, 
       0 as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract
where sentdate is not null
GROUP BY SentDate

UNION ALL
select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       count(TotalReturnMail) as TotalReturnMail, 
       0 as TraceReturnedMail
from MailDataExtract MDE
where MDE.ReturnMailDate is not null
GROUP BY  MDE.ReturnMailDate

UNION ALL

select MDE.ReturnMailDate AS 'ReceiptDate', 
       0 AS TotalMailed, 
       0 as TotalReturnMail, 
       count(TraceReturnedMail) as TraceReturnedMail

from MailDataExtract MDE
    inner join DTSharedData.dbo.ScanData SD 
        ON SD.ScanDataID = MDE.ReturnScanDataID
   where MDE.ReturnMailDate is not null AND SD.ReturnMailTypeID = 1
GROUP BY MDE.ReturnMailDate

) as Detail
GROUP BY Detail.ReceiptDate
ORDER BY 1

You can have it this way:

It is important to mind the commas after each struct item or set of items.

earnings := []LineItemsType{

        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
        LineItemsType{

            TypeName: "Earnings",

            Totals: 0.0,

            HasTotal: true,

            items: []LineItems{

                LineItems{

                    name: "Basic Pay",

                    amount: 100.0,
                },

                LineItems{

                    name: "Commuter Allowance",

                    amount: 100.0,
                },
            },
        },
    }

The code for percent sign in NSString format is %%. This is also true for NSLog() and printf() formats.

That might because you sent an Ajax request, at the same time you jump your page to another one using location.href or something like that. So the previous request failed.

I was hoping to find a solution to this as well. I see that this is an older post, but hoping my approach might simplify this problem for someone else.

I was using a combobox with a drop down style of DropDownList, but this should work with other styles. In my case I wanted the text to read "Select Source" and I wanted the other options to be "File" and "Folder"

comboBox1.Items.AddRange(new string[] {"Select Source", "File", "Folder" });
comboBox1.Text = "Select Source";

You can select the 0 index instead if you like. I then removed the "Select Source" item when the index is changed as it no longer matters if that text is visible.

comboBox1.SelectedIndexChanged += new EventHandler(comboBox1_IndexChanged);

private void comboBox1_IndexChanged(object sender, EventArgs e)
    {
        comboBox1.Items.Remove("Select Source");
        if (comboBox1.SelectedIndex != -1)
        {
            if (comboBox1.SelectedIndex == 0) // File
            {
                // Do things
            }
            else if (comboBox1.SelectedIndex == 1) // Folder
            {
                // Do things
            }
        }
    }

Thanks

just do something like this:

        ListIterator<String> it = list1.listIterator();
        int index = -1;
        while (it.hasNext()) {
            index++;
            String value = it.next();
            //At this point the index can be checked for the current element.

        }

Open Terminal and execute commands given below.

cd /etc
subl bashrc

subl denotes Sublime editor. You can replace subl with vi to open bashrc file in default editor. This will workout only if you have bashrc file, created earlier.

The content is not ready yet, you can move your js to the end of the file or do

<script>
$(function () { 
    $( '.expand' ).click(function() {
       $( '.img_display_content' ).show();
    });
});

So that the document waits to be loaded before running.

There is a much simpler way. Put your picture in a comment box within the description cell. That way you only have one column and when you sort the picture will always stay with the description. Okay... Right click the cell containing the description... Insert comment...right click the outer border... Format comment...colours and lines tab... Colour drop down...Fill effects...Picture tab...select picture...browse for your picture (it might be best to keep all pictures in one folder for ease of placement)...ok... you will probably need to go to the size tab and frig around with the height and width. Done... You now only need to mouse over the red in the top right corner of the cell and the picture will appear...like magic.

This method means that the row height can be kept to a minimum and the pictures can be as big as you like.

This is a modified version of Tim Post's method; I used /dev/tty instead of /dev/stdout. I don't know why it doesn't work with stdout (which is a link to /proc/self/fd/1):

freopen("log.txt","w",stdout);
...
...
freopen("/dev/tty","w",stdout);

By using /dev/tty the output is redirected to the terminal from where the app was launched.

Hope this info is useful.

You can use background-size: cover;

Mehrdad Afshari's answer would do the trick, but I found it a bit too verbose for this simple task. Look-up tables can sometimes do wonders:

#include <iostream>
#include <ctime>
#include <unistd.h>

using namespace std;

string gen_random(const int len) {
    
    string tmp_s;
    static const char alphanum[] =
        "0123456789"
        "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
        "abcdefghijklmnopqrstuvwxyz";
    
    srand( (unsigned) time(NULL) * getpid());

    tmp_s.reserve(len);

    for (int i = 0; i < len; ++i) 
        tmp_s += alphanum[rand() % (sizeof(alphanum) - 1)];
    
    
    return tmp_s;
    
}

int main(int argc, char *argv[]) {
    
    cout << gen_random(12) << endl;
    
    return 0;
}

Code is below:

set datefirst 7
declare @dt datetime='29/04/2016 00:00:00'
select (day(@dt)+datepart(WEEKDAY,dateadd(d,-day(@dt),@dt+1)))/7

yeah, but as @supersan stated upper in a comment, if you delete() on a QueryBuilder, the model event will not be fired, because we are not loading the model itself, then calling delete() on that model.

The events are fired only if we use the delete function on a Model Instance.

So, this beeing said:

if user->hasMany(post)
and if post->hasMany(tags)

in order to delete the post tags when deleting the user, we would have to iterate over $user->posts and calling $post->delete()

foreach($user->posts as $post) { $post->delete(); } -> this will fire the deleting event on Post

VS

$user->posts()->delete() -> this will not fire the deleting event on post because we do not actually load the Post Model (we only run a SQL like: DELETE * from posts where user_id = $user->id and thus, the Post model is not even loaded)

I just spent the last few hours on this same issue... Just go here "http://www.ftdichip.com/Drivers/VCP.htm", download the latest drivers and reboot. Should work just fine after that. I also downloaded a nightly of the Arduino software, but I don't hunk that made a difference.

I also had this problem. The solution that worked in my case was using the tabindex property on the HTML element.

I was using ng-repeat for some li elements inside a list and I was not able to bring focus to the first li using .focus(), so I simply added the tabindex attribute to each li during the loop.

so now <li ng-repeat="user in users track by $index" tabindex="{{$index+1}}"></li>

That +1 was index starts from 0. Also make sure that the element is present in DOM before calling the .focus() function

I hope this helps.

ALTER TABLE `ALLITEMS`
    CHANGE COLUMN `itemid` `itemid` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT;

I actually solved this much more easily by adding to the end of build-debug.xconfig

#include "../Pods/Target Support Files/Pods-IAP/Pods-IAP.debug.xcconfig"

And to the end of build-release.xconfig

#include "../Pods/Target Support Files/Pods-IAP/Pods-IAP.release.xcconfig"

since those files already define PODS_ROOT and the related build variables.

Remove existing origin and add new origin to your project directory

>$ git remote show origin

>$ git remote rm origin

>$ git add .

>$ git commit -m "First commit"

>$ git remote add origin Copied_origin_url

>$ git remote show origin

>$ git push origin master

You are almost always better off using an options hash.

def ldap_get(base_dn, filter, options = {})
  options[:scope] ||= LDAP::LDAP_SCOPE_SUBTREE
  ...
end

ldap_get(base_dn, filter, :attrs => X)

Do you need to retrieve the object even after the application shutting donw or just during it's running ?

You can store it into a database.
Or Simply create a custom Application class.

public class MyApplication extends Application {

    private static Object mMyObject;
    // static getter & setter
    ...
}

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
    <application ... android:name=".MyApplication">
        <activity ... />
        ...
    </application>
    ...
</manifest>

And then from every activities do :

((MyApplication) getApplication).getMyObject();

Not really the best way but it works.

This link was helpful . It contains the javascript code to detect all versions of IE up to IE11. I tested the script with IE11 emulator. To find the IE11 emulator, right-click on the web browser click "Inspect element". At the bottom-left of the page, scroll down the navigation bar and click the desktop icon. The "User Agent String" dropdown box contains options to emulate IE6-11.

It works. I just used it some minutes before writing this answer. Cannot post snapshots - not enough reputation.

If you want to add two columns together, all you have to do is add them. Then you will get the sum of those two columns for each row returned by the query.

What your code is doing is adding the two columns together and then getting a sum of the sums. That will work, but it might not be what you are attempting to accomplish.

None of the solutions worked except this one. Replacing "Pylance" or "Microsoft" in the settings.json solved mine.

"python.languageServer": "Jedi"

Showing the above explanations in action in a simple console program:

class Program
{
    static void Main(string[] args)
    {
        TestAsyncAwaitMethods();
        Console.WriteLine("Press any key to exit...");
        Console.ReadLine();
    }

    public async static void TestAsyncAwaitMethods()
    {
        await LongRunningMethod();
    }

    public static async Task<int> LongRunningMethod()
    {
        Console.WriteLine("Starting Long Running method...");
        await Task.Delay(5000);
        Console.WriteLine("End Long Running method...");
        return 1;
    }
}

And the output is:

Starting Long Running method...
Press any key to exit...
End Long Running method...

Thus,

1. Main starts the long running method via TestAsyncAwaitMethods. That immediately returns without halting the current thread and we immediately see 'Press any key to exit' message
2. All this while, the LongRunningMethod is running in the background. Once its completed, another thread from Threadpool picks up this context and displays the final message

Thus, not thread is blocked.

Given the general support of .innerHTML these days, the only effective difference now is that .html() will execute code in any <script> tags if there are any in the html you give it. .innerHTML, under HTML5, will not.

From the jQuery docs:

By design, any jQuery constructor or method that accepts an HTML string — jQuery(), .append(), .after(), etc. — can potentially execute code. This can occur by injection of script tags or use of HTML attributes that execute code (for example, <img onload="">). Do not use these methods to insert strings obtained from untrusted sources such as URL query parameters, cookies, or form inputs. Doing so can introduce cross-site-scripting (XSS) vulnerabilities. Remove or escape any user input before adding content to the document.

Note: both .innerHTML and .html() can execute js other ways (e.g the onerror attribute).

Quote, which summarizes from this article:

1. SET is the ANSI standard for variable assignment, SELECT is not.
2. SET can only assign one variable at a time, SELECT can make multiple assignments at once.
3. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
4. When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from its previous value)
5. As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

The accepted answer needs a little clarification. The row will be there if CLR is enabled or disabled. Value will be 1 if enabled, or 0 if disabled.

I use this script to enable on a server, if the option is disabled:

if not exists(
    SELECT value
    FROM sys.configurations
    WHERE name = 'clr enabled'
     and value = 1
)
begin
    exec sp_configure @configname=clr_enabled, @configvalue=1
    reconfigure
end

From spark 3.0

data_cl = reg_data.exceptAll(data_fr)

The best way would be to avoid booleans completely, since every boolean implies that you have a conditional statement anywhere else in your code (see http://www.antiifcampaign.com/ and this question: Can you write any algorithm without an if statement?).

However, pragmatically you have to use booleans from time to time, but, as you have already found out by yourself, dealing with Booleans is more error prone and more cumbersome. So I would suggest using booleans wherever possible. Exceptions from this might be a legacy database with nullable boolean-columns, although I would try to hide that in my mapping as well.

First of all what value do you have in this pice of code? int temp;? You can't tell because in every single compilation it will have different value - you should initialize your value to not have trash value from memory. Next question is: why you assign this temp value to your array? If you want to stick with your solution I would change reverse function like this:

void reverse(int arr[], int count)
{
    int temp = 0;
    for (int i = 0; i < count/2; ++i)
    {
        temp = arr[count - i - 1];
        arr[count - i - 1] = arr[i];
        arr[i] = temp;
    }

    for (int i = 0; i < count; ++i)
    {
        std::cout << arr[i] << " ";
    }
}

Now it will works but you have other options to handle this problem.

Solution using pointers:

void reverse(int arr[], int count)
{
    int* head = arr;
    int* tail = arr + count - 1;
    for (int i = 0; i < count/2; ++i)
    {
        if (head < tail)
        {
            int tmp = *tail;
            *tail = *head;
            *head = tmp;

            head++; tail--;
        }
    }

    for (int i = 0; i < count; ++i)
    {
        std::cout << arr[i] << " ";
    }
}

And ofc like Carlos Abraham says use build in function in algorithm library

Some of the reflection compare methods are shallow

Another option is to convert the object to a json and compare the strings.

import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;    
public static String getJsonString(Object obj) {
 try {
    ObjectMapper objectMapper = new ObjectMapper();
    return bjectMapper.writerWithDefaultPrettyPrinter().writeValueAsString(obj);
     } catch (JsonProcessingException e) {
        LOGGER.error("Error parsing log entry", e);
        return null;
    }
}
...
assertEquals(getJsonString(MyexpectedObject), getJsonString(MyActualObject))

Here comes Linq:

var listItem = list.Single(i => i.Title == title);

It throws an exception if there's no item matching the predicate. Alternatively, there's SingleOrDefault.

If you want a collection of items matching the title, there's:

var listItems = list.Where(i => i.Title ==  title);

Newcomer to Python, I had this issue when I was using the Python's ** feature in a wrong way. Trying to call this definition from somewhere:

def create_properties_frame(self, parent, **kwargs):

using a call without a double star was causing the problem:

self.create_properties_frame(frame, kw_gsp)

TypeError: create_properties_frame() takes 2 positional arguments but 3 were given

The solution is to add ** to the argument:

self.create_properties_frame(frame, **kw_gsp)

How are you? I had the same problem while i was trying connect to MSSQL Server remotely using jdbc (dbeaver on debian).

After a while, i found out that my firewall configuration was not correctly. So maybe it could help you!

Configure the firewall to allow network traffic that is related to SQL Server and to the SQL Server Browser service.

Four exceptions must be configured in Windows Firewall to allow access to SQL Server:

A port exception for TCP Port 1433. In the New Inbound Rule Wizard dialog, use the following information to create a port exception: Select Port Select TCP and specify port 1433 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – TCP 1433" A port exception for UDP Port 1434. Click New Rule again and use the following information to create another port exception: Select Port Select UDP and specify port 1434 Allow the connection Choose all three profiles (Domain, Private & Public) Name the rule “SQL – UDP 1434 A program exception for sqlservr.exe.

For iTunes 12, drag the .ipa file from the Finder to the Apps area NOT inside your device (in iTunes)... alternately, you can just double click on the .ipa in the Finder.

Important note: you have to change Version and/or Build number. Otherwise, you get no notice from iTunes at all...

Then switch to your device in iTunes, and install or update the application.

Then hit sync.

If other whitespace characters are possible, then you'd want:

testString.split("\\s+");

Python is dynamic language so the IDE can do only so much in terms of code intelligence and syntax checking but I personally recommend Komode IDE, it's pretty slick on OS/X and Windows. I've experienced high cpu use with Linux but not sure if it's caused by my VirtualBox environment.

You can also try Eclipse with PyDev plugin. It's heavier so performance might become a problem though.

OPTION 1 worked for me, in PHP 7, and for sure it does in PHP 5 too. And the global scope declaration is not necessary for the included file for variables access, the included - or "required" - files are part of the script, only be sure you make the "include" AFTER the variable declaration. Maybe you have some misconfiguration with variables global scope in your PHP.ini?

Try in first file:

  <?php 
  $myvariable="from first file";
  include ("./mysecondfile.php"); // in same folder as first file LOLL
  ?>

mysecondfile.php

  <?php 
  echo "this is my variable ". $myvariable;
  ?>

It should work... if it doesn't just try to reinstall PHP.

Normally updating certifi and/or the certifi cacert.pem file would work. I also had to update my version of python. Vs. 2.7.5 wasn't working because of how it handles SNI requests.

Once you have an up to date pem file you can make your http request using:

requests.get(url, verify='/path/to/cacert.pem')

By using a simple for..in loop:

for(var key in objects) {
    var value = objects[key];
}

CodeIgniter returns result rows as objects, not arrays. From the user guide:

result()

---

This function returns the query result as an array of objects, or an empty array on failure.

You'll have to access the fields using the following notation:

foreach ($getvidids->result() as $row) {
    $vidid = $row->videoid;
}

Indeed, the keyword is "ajax": Asynchronous JavaScript and XML. However, last years it's more than often Asynchronous JavaScript and JSON. Basically, you let JS execute an asynchronous HTTP request and update the HTML DOM tree based on the response data.

Since it's pretty a tedious work to make it to work across all browsers (especially Internet Explorer versus others), there are plenty of JavaScript libraries out which simplifies this in single functions and covers as many as possible browser-specific bugs/quirks under the hoods, such as jQuery, Prototype, Mootools. Since jQuery is most popular these days, I'll use it in the below examples.

Kickoff example returning String as plain text

Create a /some.jsp like below (note: the code snippets in this answer doesn't expect the JSP file being placed in a subfolder, if you do so, alter servlet URL accordingly from "someservlet" to "${pageContext.request.contextPath}/someservlet"; it's merely omitted from the code snippets for brevity):

<!DOCTYPE html>
<html lang="en">
    <head>
        <title>SO question 4112686</title>
        <script src="http://code.jquery.com/jquery-latest.min.js"></script>
        <script>
            $(document).on("click", "#somebutton", function() { // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
                $.get("someservlet", function(responseText) {   // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response text...
                    $("#somediv").text(responseText);           // Locate HTML DOM element with ID "somediv" and set its text content with the response text.
                });
            });
        </script>
    </head>
    <body>
        <button id="somebutton">press here</button>
        <div id="somediv"></div>
    </body>
</html>

Create a servlet with a doGet() method which look like this:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String text = "some text";

    response.setContentType("text/plain");  // Set content type of the response so that jQuery knows what it can expect.
    response.setCharacterEncoding("UTF-8"); // You want world domination, huh?
    response.getWriter().write(text);       // Write response body.
}

Map this servlet on an URL pattern of /someservlet or /someservlet/* as below (obviously, the URL pattern is free to your choice, but you'd need to alter the someservlet URL in JS code examples over all place accordingly):

package com.example;

@WebServlet("/someservlet/*")
public class SomeServlet extends HttpServlet {
    // ...
}

Or, when you're not on a Servlet 3.0 compatible container yet (Tomcat 7, Glassfish 3, JBoss AS 6, etc or newer), then map it in web.xml the old fashioned way (see also our Servlets wiki page):

<servlet>
    <servlet-name>someservlet</servlet-name>
    <servlet-class>com.example.SomeServlet</servlet-class>
</servlet>
<servlet-mapping>
    <servlet-name>someservlet</servlet-name>
    <url-pattern>/someservlet/*</url-pattern>
</servlet-mapping>

Now open the http://localhost:8080/context/test.jsp in the browser and press the button. You'll see that the content of the div get updated with the servlet response.

Returning List<String> as JSON

With JSON instead of plaintext as response format you can even get some steps further. It allows for more dynamics. First, you'd like to have a tool to convert between Java objects and JSON strings. There are plenty of them as well (see the bottom of this page for an overview). My personal favourite is Google Gson. Download and put its JAR file in /WEB-INF/lib folder of your webapplication.

Here's an example which displays List<String> as <ul><li>. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<String> list = new ArrayList<>();
    list.add("item1");
    list.add("item2");
    list.add("item3");
    String json = new Gson().toJson(list);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

The JS code:

$(document).on("click", "#somebutton", function() {  // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {    // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $ul = $("<ul>").appendTo($("#somediv")); // Create HTML <ul> element and append it to HTML DOM element with ID "somediv".
        $.each(responseJson, function(index, item) { // Iterate over the JSON array.
            $("<li>").text(item).appendTo($ul);      // Create HTML <li> element, set its text content with currently iterated item and append it to the <ul>.
        });
    });
});

Do note that jQuery automatically parses the response as JSON and gives you directly a JSON object (responseJson) as function argument when you set the response content type to application/json. If you forget to set it or rely on a default of text/plain or text/html, then the responseJson argument wouldn't give you a JSON object, but a plain vanilla string and you'd need to manually fiddle around with JSON.parse() afterwards, which is thus totally unnecessary if you set the content type right in first place.

Returning Map<String, String> as JSON

Here's another example which displays Map<String, String> as <option>:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    Map<String, String> options = new LinkedHashMap<>();
    options.put("value1", "label1");
    options.put("value2", "label2");
    options.put("value3", "label3");
    String json = new Gson().toJson(options);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

And the JSP:

$(document).on("click", "#somebutton", function() {               // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {                 // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $select = $("#someselect");                           // Locate HTML DOM element with ID "someselect".
        $select.find("option").remove();                          // Find all child elements with tag name "option" and remove them (just to prevent duplicate options when button is pressed again).
        $.each(responseJson, function(key, value) {               // Iterate over the JSON object.
            $("<option>").val(key).text(value).appendTo($select); // Create HTML <option> element, set its value with currently iterated key and its text content with currently iterated item and finally append it to the <select>.
        });
    });
});

with

<select id="someselect"></select>

Returning List<Entity> as JSON

Here's an example which displays List<Product> in a <table> where the Product class has the properties Long id, String name and BigDecimal price. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<Product> products = someProductService.list();
    String json = new Gson().toJson(products);

    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(json);
}

The JS code:

$(document).on("click", "#somebutton", function() {        // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseJson) {          // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response JSON...
        var $table = $("<table>").appendTo($("#somediv")); // Create HTML <table> element and append it to HTML DOM element with ID "somediv".
        $.each(responseJson, function(index, product) {    // Iterate over the JSON array.
            $("<tr>").appendTo($table)                     // Create HTML <tr> element, set its text content with currently iterated item and append it to the <table>.
                .append($("<td>").text(product.id))        // Create HTML <td> element, set its text content with id of currently iterated product and append it to the <tr>.
                .append($("<td>").text(product.name))      // Create HTML <td> element, set its text content with name of currently iterated product and append it to the <tr>.
                .append($("<td>").text(product.price));    // Create HTML <td> element, set its text content with price of currently iterated product and append it to the <tr>.
        });
    });
});

Returning List<Entity> as XML

Here's an example which does effectively the same as previous example, but then with XML instead of JSON. When using JSP as XML output generator you'll see that it's less tedious to code the table and all. JSTL is this way much more helpful as you can actually use it to iterate over the results and perform server side data formatting. The servlet:

@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    List<Product> products = someProductService.list();

    request.setAttribute("products", products);
    request.getRequestDispatcher("/WEB-INF/xml/products.jsp").forward(request, response);
}

The JSP code (note: if you put the <table> in a <jsp:include>, it may be reusable elsewhere in a non-ajax response):

<?xml version="1.0" encoding="UTF-8"?>
<%@page contentType="application/xml" pageEncoding="UTF-8"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt" %>
<data>
    <table>
        <c:forEach items="${products}" var="product">
            <tr>
                <td>${product.id}</td>
                <td><c:out value="${product.name}" /></td>
                <td><fmt:formatNumber value="${product.price}" type="currency" currencyCode="USD" /></td>
            </tr>
        </c:forEach>
    </table>
</data>

The JS code:

$(document).on("click", "#somebutton", function() {             // When HTML DOM "click" event is invoked on element with ID "somebutton", execute the following function...
    $.get("someservlet", function(responseXml) {                // Execute Ajax GET request on URL of "someservlet" and execute the following function with Ajax response XML...
        $("#somediv").html($(responseXml).find("data").html()); // Parse XML, find <data> element and append its HTML to HTML DOM element with ID "somediv".
    });
});

You'll by now probably realize why XML is so much more powerful than JSON for the particular purpose of updating a HTML document using Ajax. JSON is funny, but after all generally only useful for so-called "public web services". MVC frameworks like JSF use XML under the covers for their ajax magic.

Ajaxifying an existing form

You can use jQuery $.serialize() to easily ajaxify existing POST forms without fiddling around with collecting and passing the individual form input parameters. Assuming an existing form which works perfectly fine without JavaScript/jQuery (and thus degrades gracefully when enduser has JavaScript disabled):

<form id="someform" action="someservlet" method="post">
    <input type="text" name="foo" />
    <input type="text" name="bar" />
    <input type="text" name="baz" />
    <input type="submit" name="submit" value="Submit" />
</form>

You can progressively enhance it with ajax as below:

$(document).on("submit", "#someform", function(event) {
    var $form = $(this);

    $.post($form.attr("action"), $form.serialize(), function(response) {
        // ...
    });

    event.preventDefault(); // Important! Prevents submitting the form.
});

You can in the servlet distinguish between normal requests and ajax requests as below:

@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String foo = request.getParameter("foo");
    String bar = request.getParameter("bar");
    String baz = request.getParameter("baz");

    boolean ajax = "XMLHttpRequest".equals(request.getHeader("X-Requested-With"));

    // ...

    if (ajax) {
        // Handle ajax (JSON or XML) response.
    } else {
        // Handle regular (JSP) response.
    }
}

The jQuery Form plugin does less or more the same as above jQuery example, but it has additional transparent support for multipart/form-data forms as required by file uploads.

Manually sending request parameters to servlet

If you don't have a form at all, but just wanted to interact with the servlet "in the background" whereby you'd like to POST some data, then you can use jQuery $.param() to easily convert a JSON object to an URL-encoded query string.

var params = {
    foo: "fooValue",
    bar: "barValue",
    baz: "bazValue"
};

$.post("someservlet", $.param(params), function(response) {
    // ...
});

The same doPost() method as shown here above can be reused. Do note that above syntax also works with $.get() in jQuery and doGet() in servlet.

Manually sending JSON object to servlet

If you however intend to send the JSON object as a whole instead of as individual request parameters for some reason, then you'd need to serialize it to a string using JSON.stringify() (not part of jQuery) and instruct jQuery to set request content type to application/json instead of (default) application/x-www-form-urlencoded. This can't be done via $.post() convenience function, but needs to be done via $.ajax() as below.

var data = {
    foo: "fooValue",
    bar: "barValue",
    baz: "bazValue"
};

$.ajax({
    type: "POST",
    url: "someservlet",
    contentType: "application/json", // NOT dataType!
    data: JSON.stringify(data),
    success: function(response) {
        // ...
    }
});

Do note that a lot of starters mix contentType with dataType. The contentType represents the type of the request body. The dataType represents the (expected) type of the response body, which is usually unnecessary as jQuery already autodetects it based on response's Content-Type header.

Then, in order to process the JSON object in the servlet which isn't being sent as individual request parameters but as a whole JSON string the above way, you only need to manually parse the request body using a JSON tool instead of using getParameter() the usual way. Namely, servlets don't support application/json formatted requests, but only application/x-www-form-urlencoded or multipart/form-data formatted requests. Gson also supports parsing a JSON string into a JSON object.

JsonObject data = new Gson().fromJson(request.getReader(), JsonObject.class);
String foo = data.get("foo").getAsString();
String bar = data.get("bar").getAsString();
String baz = data.get("baz").getAsString();
// ...

Do note that this all is more clumsy than just using $.param(). Normally, you want to use JSON.stringify() only if the target service is e.g. a JAX-RS (RESTful) service which is for some reason only capable of consuming JSON strings and not regular request parameters.

Sending a redirect from servlet

Important to realize and understand is that any sendRedirect() and forward() call by the servlet on an ajax request would only forward or redirect the ajax request itself and not the main document/window where the ajax request originated. JavaScript/jQuery would in such case only retrieve the redirected/forwarded response as responseText variable in the callback function. If it represents a whole HTML page and not an ajax-specific XML or JSON response, then all you could do is to replace the current document with it.

document.open();
document.write(responseText);
document.close();

Note that this doesn't change the URL as enduser sees in browser's address bar. So there are issues with bookmarkability. Therefore, it's much better to just return an "instruction" for JavaScript/jQuery to perform a redirect instead of returning the whole content of the redirected page. E.g. by returning a boolean, or an URL.

String redirectURL = "http://example.com";

Map<String, String> data = new HashMap<>();
data.put("redirect", redirectURL);
String json = new Gson().toJson(data);

response.setContentType("application/json");
response.setCharacterEncoding("UTF-8");
response.getWriter().write(json);

function(responseJson) {
    if (responseJson.redirect) {
        window.location = responseJson.redirect;
        return;
    }

    // ...
}

What parsers and lexers have in common:

1. They read symbols of some alphabet from their input.

   • Hint: The alphabet doesn't necessarily have to be of letters. But it has to be of symbols which are atomic for the language understood by parser/lexer.
   • Symbols for the lexer: ASCII characters.
   • Symbols for the parser: the particular tokens, which are terminal symbols of their grammar.

2. They analyse these symbols and try to match them with the grammar of the language they understood.
   

   • Here's where the real difference usually lies. See below for more.
   • Grammar understood by lexers: regular grammar (Chomsky's level 3).
   • Grammar understood by parsers: context-free grammar (Chomsky's level 2).

3. They attach semantics (meaning) to the language pieces they find.

   • Lexers attach meaning by classifying lexemes (strings of symbols from the input) as the particular tokens. E.g. All these lexemes: *, ==, <=, ^ will be classified as "operator" token by the C/C++ lexer.
   • Parsers attach meaning by classifying strings of tokens from the input (sentences) as the particular nonterminals and building the parse tree. E.g. all these token strings: [number][operator][number], [id][operator][id], [id][operator][number][operator][number] will be classified as "expression" nonterminal by the C/C++ parser.

4. They can attach some additional meaning (data) to the recognized elements.

   • When a lexer recognizes a character sequence constituting a proper number, it can convert it to its binary value and store with the "number" token.
   • Similarly, when a parser recognize an expression, it can compute its value and store with the "expression" node of the syntax tree.

5. They all produce on their output a proper sentences of the language they recognize.

   • Lexers produce tokens, which are sentences of the regular language they recognize. Each token can have an inner syntax (though level 3, not level 2), but that doesn't matter for the output data and for the one which reads them.
   • Parsers produce syntax trees, which are representations of sentences of the context-free language they recognize. Usually it's only one big tree for the whole document/source file, because the whole document/source file is a proper sentence for them. But there aren't any reasons why parser couldn't produce a series of syntax trees on its output. E.g. it could be a parser which recognizes SGML tags sticked into plain-text. So it'll tokenize the SGML document into a series of tokens: [TXT][TAG][TAG][TXT][TAG][TXT]....

As you can see, parsers and tokenizers have much in common. One parser can be a tokenizer for other parser, which reads its input tokens as symbols from its own alphabet (tokens are simply symbols of some alphabet) in the same way as sentences from one language can be alphabetic symbols of some other, higher-level language. For example, if * and - are the symbols of the alphabet M (as "Morse code symbols"), then you can build a parser which recognizes strings of these dots and lines as letters encoded in the Morse code. The sentences in the language "Morse Code" could be tokens for some other parser, for which these tokens are atomic symbols of its language (e.g. "English Words" language). And these "English Words" could be tokens (symbols of the alphabet) for some higher-level parser which understands "English Sentences" language. And all these languages differ only in the complexity of the grammar. Nothing more.

So what's all about these "Chomsky's grammar levels"? Well, Noam Chomsky classified grammars into four levels depending on their complexity:

• Level 3: Regular grammars

  They use regular expressions, that is, they can consist only of the symbols of alphabet (a,b), their concatenations (ab,aba,bbb etd.), or alternatives (e.g. a|b).
  They can be implemented as finite state automata (FSA), like NFA (Nondeterministic Finite Automaton) or better DFA (Deterministic Finite Automaton).
  Regular grammars can't handle with nested syntax, e.g. properly nested/matched parentheses (()()(()())), nested HTML/BBcode tags, nested blocks etc. It's because state automata to deal with it should have to have infinitely many states to handle infinitely many nesting levels.

• Level 2: Context-free grammars

  They can have nested, recursive, self-similar branches in their syntax trees, so they can handle with nested structures well.
  They can be implemented as state automaton with stack. This stack is used to represent the nesting level of the syntax. In practice, they're usually implemented as a top-down, recursive-descent parser which uses machine's procedure call stack to track the nesting level, and use recursively called procedures/functions for every non-terminal symbol in their syntax.
  But they can't handle with a context-sensitive syntax. E.g. when you have an expression x+3 and in one context this x could be a name of a variable, and in other context it could be a name of a function etc.

• Level 1: Context-sensitive grammars

• Level 0: Unrestricted grammars
  Also called recursively enumerable grammars.

Not really. Internally, passing by reference is performed by essentially passing the address of the referenced object. So, there really aren't any efficiency gains to be had by passing a pointer.

Passing by reference does have one benefit, however. You are guaranteed to have an instance of whatever object/type that is being passed in. If you pass in a pointer, then you run the risk of receiving a NULL pointer. By using pass-by-reference, you are pushing an implicit NULL-check up one level to the caller of your function.

I had the same problem after upgrading a bunch of NuGet packages.
I have tried all kinds of deleting, cleaning, resintalling described here and beyong to no avail. The references did not have Microsoft.Web.Infrastructure despite the NuGet manager showed it was installed.

The problem was solved by replacing:

  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net45" />

with

  <package id="Microsoft.Web.Infrastructure" version="1.0.0.0" targetFramework="net46" />

in packages.config. The culprit is apparently "net45".

Anybody can try the following (mailto function only accepts plaintext but here i show how to use HTML innertext properties and how to add an anchor as mailto body params):

//Create as many html elements you need.

const titleElement = document.createElement("DIV");
titleElement.innerHTML = this.shareInformation.title; // Just some string

//Here I create an <a> so I can use href property
const titleLinkElement = document.createElement("a");
titleLinkElement.href = this.shareInformation.link; // This is a url

...

let mail = document.createElement("a");

// Using es6 template literals add the html innerText property and anchor element created to mailto body parameter
mail.href = 
  `mailto:?subject=${titleElement.innerText}&body=${titleLinkElement}%0D%0A${abstractElement.innerText}`;
mail.click();

// Notice how I use ${titleLinkElement} that is an anchor element, so mailto uses its href and renders the url I needed

On some investigation, the answer appears to be (a).

When I go to change the settings, the settings file goes into a .vscode directory in my project directory.

I've always used to get a list of enum values like this:

Array list = Enum.GetValues(typeof (SomeEnum));

Do not simplify the code to avoid "linq translation error": The test consist between a date with time at 0:0:0 and the same date with time at 23:59:59

        iFilter.MyDate1 = DateTime.Today;  // or DateTime.MinValue

        // GET 
        var tempQuery = ctx.MyTable.AsQueryable();

        if (iFilter.MyDate1 != DateTime.MinValue)
        {
            TimeSpan temp24h = new TimeSpan(23,59,59);
            DateTime tempEndMyDate1 = iFilter.MyDate1.Add(temp24h);

            // DO not change the code below, you need 2 date variables...
            tempQuery = tempQuery.Where(w => w.MyDate2 >= iFilter.MyDate1
                                          && w.MyDate2 <= tempEndMyDate1);
        }

        List<MyTable> returnObject = tempQuery.ToList();

you can use pure javascript atob() function to decode token into a string:

atob(token.split('.')[1]);

or parse directly it into a json object:

JSON.parse(atob(token.split('.')[1]));

read about atob() and btoa() built-in javascript functions Base64 encoding and decoding - Web APIs | MDN.

The following code works with multiple types of archives (jar, war) and multiple types of classloaders (jar, url, vfs, ...)

  public static Manifest getManifest(Class<?> clz) {
    String resource = "/" + clz.getName().replace(".", "/") + ".class";
    String fullPath = clz.getResource(resource).toString();
    String archivePath = fullPath.substring(0, fullPath.length() - resource.length());
    if (archivePath.endsWith("\\WEB-INF\\classes") || archivePath.endsWith("/WEB-INF/classes")) {
      archivePath = archivePath.substring(0, archivePath.length() - "/WEB-INF/classes".length()); // Required for wars
    }

    try (InputStream input = new URL(archivePath + "/META-INF/MANIFEST.MF").openStream()) {
      return new Manifest(input);
    } catch (Exception e) {
      throw new RuntimeException("Loading MANIFEST for class " + clz + " failed!", e);
    }
  }

A complete time-string contains:

• date
• time
• utcoffset [+HHMM or -HHMM]

For example:

1970-01-01 06:00:00 +0500 == 1970-01-01 01:00:00 +0000 == UNIX timestamp:3600

$ python3
>>> from datetime import datetime
>>> from calendar import timegm
>>> tm = '1970-01-01 06:00:00 +0500'
>>> fmt = '%Y-%m-%d %H:%M:%S %z'
>>> timegm(datetime.strptime(tm, fmt).utctimetuple())
3600

Note:

UNIX timestamp is a floating point number expressed in seconds since the epoch, in UTC.

Edit:

$ python3
>>> from datetime import datetime, timezone, timedelta
>>> from calendar import timegm
>>> dt = datetime(1970, 1, 1, 6, 0)
>>> tz = timezone(timedelta(hours=5))
>>> timegm(dt.replace(tzinfo=tz).utctimetuple())
3600

If you have short strings you should be able to create a few LIKE patterns ('[^a-zA-Z0-9]', '[^a-zA-Z0-9][^a-zA-Z0-9]', ...) to match strings of different length. Otherwise you should use CLR user defined function and a proper regular expression - Regular Expressions Make Pattern Matching And Data Extraction Easier.

The dictionary with histories of "acc", "loss", etc. is available and saved in hist.history variable.

Unfortunately, the answer to your question of whether there is official Material support for selecting the time is "No", but it's currently an open issue on the official Material2 GitHub repo: https://github.com/angular/material2/issues/5648

Hopefully this changes soon, in the mean time, you'll have to fight with the 3rd-party ones you've already discovered. There are a few people in that GitHub issue that provide their self-made workarounds that you can try.

It's not pretty, but the way I resign the firstResponder when I don't know what that the responder is:

Create an UITextField, either in IB or programmatically. Make it Hidden. Link it up to your code if you made it in IB.

Then, when you want to dismiss the keyboard, you switch the responder to the invisible text field, and immediately resign it:

    [self.invisibleField becomeFirstResponder];
    [self.invisibleField resignFirstResponder];

fun convertLongToTimeWithLocale(){
    val dateAsMilliSecond: Long = 1602709200000
    val date = Date(dateAsMilliSecond)
    val language = "en"
    val formattedDateAsDigitMonth = SimpleDateFormat("dd/MM/yyyy", Locale(language))
    val formattedDateAsShortMonth = SimpleDateFormat("dd MMM yyyy", Locale(language))
    val formattedDateAsLongMonth = SimpleDateFormat("dd MMMM yyyy", Locale(language))
    Log.d("month as digit", formattedDateAsDigitMonth.format(date))
    Log.d("month as short", formattedDateAsShortMonth.format(date))
    Log.d("month as long", formattedDateAsLongMonth.format(date))
}

output:

month as digit: 15/10/2020
month as short: 15 Oct 2020 
month as long : 15 October 2020

You can change the value defined as 'language' due to your require. Here is the all language codes: Java language codes

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>

If there are multiple threads accessing class level variable then each thread can keep copy of that variable in its threadlocal cache.

Making the variable volatile will prevent threads from keeping the copy of variable in threadlocal cache.

Atomic variables are different and they allow atomic modification of their values.

No, but you might consider using a set of functions (or macros) to approximate using default args:

// No default args
int foo3(int a, int b, int c)
{
    return ...;
}

// Default 3rd arg
int foo2(int a, int b)
{
    return foo3(a, b, 0);  // default c
}

// Default 2nd and 3rd args
int foo1(int a)
{
    return foo3(a, 1, 0);  // default b and c
}

Simple version:

$arrayObject = new ArrayObject($object);
$array = $arrayObject->getArrayCopy();

Updated recursive version:

class RecursiveArrayObject extends ArrayObject
{
    function getArrayCopy()
    {
        $resultArray = parent::getArrayCopy();
        foreach($resultArray as $key => $val) {
            if (!is_object($val)) {
                continue;
            }
            $o = new RecursiveArrayObject($val);
            $resultArray[$key] = $o->getArrayCopy();
        }
        return $resultArray;
    }
}

$arrayObject = new RecursiveArrayObject($object);
$array = $arrayObject->getArrayCopy();

I answered this question on SuperUser but only after the OP disregarded the unhelpful answer that was at the time the only answer to the question.

Here is the proper way to elevate permissions in Cygwin, copied from my own answer on SuperUser:

I found the answer on the Cygwin mailing list. To run command with elevated privileges in Cygwin, precede the command with cygstart --action=runas like this:

$ cygstart --action=runas command

This will open a Windows dialogue box asking for the Admin password and run the command if the proper password is entered.

This is easily scripted, so long as ~/bin is in your path. Create a file ~/bin/sudo with the following content:

#!/usr/bin/bash
cygstart --action=runas "$@"

Now make the file executable:

$ chmod +x ~/bin/sudo

Now you can run commands with real elevated privileges:

$ sudo elevatedCommand

You may need to add ~/bin to your path. You can run the following command on the Cygwin CLI, or add it to ~/.bashrc:

$ PATH=$HOME/bin:$PATH

Tested on 64-bit Windows 8.

You could also instead of above steps add an alias for this command to ~/.bashrc:

# alias to simulate sudo
alias sudo='cygstart --action=runas'

Yes since there are 2 distinct Global Assembly Cache (GAC), you will have to manage each of them individually.

In .NET Framework 4.0, the GAC went through a few changes. The GAC was split into two, one for each CLR.

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. There was no need in the previous two framework releases to split GAC. The problem of breaking older applications in Net Framework 4.0.

To avoid issues between CLR 2.0 and CLR 4.0 , the GAC is now split into private GAC’s for each runtime.The main change is that CLR v2.0 applications now cannot see CLR v4.0 assemblies in the GAC.

Source

Why?

It seems to be because there was a CLR change in .NET 4.0 but not in 2.0 to 3.5. The same thing happened with 1.1 to 2.0 CLR. It seems that the GAC has the ability to store different versions of assemblies as long as they are from the same CLR. They do not want to break old applications.

See the following information in MSDN about the GAC changes in 4.0.

For example, if both .NET 1.1 and .NET 2.0 shared the same GAC, then a .NET 1.1 application, loading an assembly from this shared GAC, could get .NET 2.0 assemblies, thereby breaking the .NET 1.1 application

The CLR version used for both .NET Framework 2.0 and .NET Framework 3.5 is CLR 2.0. As a result of this, there was no need in the previous two framework releases to split the GAC. The problem of breaking older (in this case, .NET 2.0) applications resurfaces in Net Framework 4.0 at which point CLR 4.0 released. Hence, to avoid interference issues between CLR 2.0 and CLR 4.0, the GAC is now split into private GACs for each runtime.

As the CLR is updated in future versions you can expect the same thing. If only the language changes then you can use the same GAC.

As of Json.NET 4.0 Release 1, there is native dynamic support:

[Test]
public void DynamicDeserialization()
{
    dynamic jsonResponse = JsonConvert.DeserializeObject("{\"message\":\"Hi\"}");
    jsonResponse.Works = true;
    Console.WriteLine(jsonResponse.message); // Hi
    Console.WriteLine(jsonResponse.Works); // True
    Console.WriteLine(JsonConvert.SerializeObject(jsonResponse)); // {"message":"Hi","Works":true}
    Assert.That(jsonResponse, Is.InstanceOf<dynamic>());
    Assert.That(jsonResponse, Is.TypeOf<JObject>());
}

And, of course, the best way to get the current version is via NuGet.

Updated (11/12/2014) to address comments:

This works perfectly fine. If you inspect the type in the debugger you will see that the value is, in fact, dynamic. The underlying type is a JObject. If you want to control the type (like specifying ExpandoObject, then do so.

Here you can find also add watermark codes in this class :

public class ImageProcessor
    {
        public Bitmap Resize(Bitmap image, int newWidth, int newHeight, string message)
        {
            try
            {
                Bitmap newImage = new Bitmap(newWidth, Calculations(image.Width, image.Height, newWidth));

                using (Graphics gr = Graphics.FromImage(newImage))
                {
                    gr.SmoothingMode = SmoothingMode.AntiAlias;
                    gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
                    gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
                    gr.DrawImage(image, new Rectangle(0, 0, newImage.Width, newImage.Height));

                    var myBrush = new SolidBrush(Color.FromArgb(70, 205, 205, 205));

                    double diagonal = Math.Sqrt(newImage.Width * newImage.Width + newImage.Height * newImage.Height);

                    Rectangle containerBox = new Rectangle();

                    containerBox.X = (int)(diagonal / 10);
                    float messageLength = (float)(diagonal / message.Length * 1);
                    containerBox.Y = -(int)(messageLength / 1.6);

                    Font stringFont = new Font("verdana", messageLength);

                    StringFormat sf = new StringFormat();

                    float slope = (float)(Math.Atan2(newImage.Height, newImage.Width) * 180 / Math.PI);

                    gr.RotateTransform(slope);
                    gr.DrawString(message, stringFont, myBrush, containerBox, sf);
                    return newImage;
                }
            }
            catch (Exception exc)
            {
                throw exc;
            }
        }

        public int Calculations(decimal w1, decimal h1, int newWidth)
        {
            decimal height = 0;
            decimal ratio = 0;


            if (newWidth < w1)
            {
                ratio = w1 / newWidth;
                height = h1 / ratio;

                return height.To<int>();
            }

            if (w1 < newWidth)
            {

            }

            return height.To<int>();
        }

    }

I had the same problem, you have to load first the Moment.js file!

<script src="path/moment.js"></script>_x000D_
<script src="path/bootstrap-datetimepicker.js"></script>

&a gives address of a - &p gives address of p.

int * * p_to_p = &p;

If you are using WAMP then type the following in the browser
http://localhost/?phpinfo=-1, you will get the phpinfo page.

phpinfo() from localhost

You can also click the localhost icon in the wamp menu from the systray and then find the phpinfo page. WAMP localhost from WAMP Menu

Basically all you need to do is add $ as prefix at column letter and row number. Please see image below

I think you can do it in Rx way like:

 timerSubscribe = Observable.interval(1, TimeUnit.SECONDS)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Action1<Long>() {
                @Override
                public void call(Long aLong) {
                      //TODO do your stuff
                }
            });

And cancel this like:

timerSubscribe.unsubscribe();

Rx Timer http://reactivex.io/documentation/operators/timer.html

You can't jump ahead without reading in the file at least once, since you don't know where the line breaks are. You could do something like:

# Read in the file once and build a list of line offsets
line_offset = []
offset = 0
for line in file:
    line_offset.append(offset)
    offset += len(line)
file.seek(0)

# Now, to skip to line n (with the first line being line 0), just do
file.seek(line_offset[n])

if var sum=0; var x;

then, what about this? sum+=(x|0);

I know I am late, but if you want to know the easiest way, you could do a code like this:

number = 100
right_questions = 1
control = 100
c = control / number
cc = right_questions * c
print float(cc)

You can change up the number score, and right_questions. It will tell you the percent.

Because you are asking the compiler to initialize a static variable with code that is inherently dynamic.

Any suggestions/examples? I followed SwingWorker... The code was very messy and I don't like this approach.

Instead of get(), which waits for completion, use process() and setProgress() to show intermediate results, as suggested in this simple example or this related example.

The %b option of sprintf() will convert a boolean to an integer:

echo sprintf("False will print as %b", false); //False will print as 0
echo sprintf("True will print as %b", true); //True will print as 1

If you're not familiar with it: You can give this function an arbitrary amount of parameters while the first one should be your ouput string spiced with replacement strings like %b or %s for general string replacement.

Each pattern will be replaced by the argument in order:

echo sprintf("<h1>%s</h1><p>%s<br/>%s</p>", "Neat Headline", "First Line in the paragraph", "My last words before this demo is over");

function Array2D(x, y)
{
    var array2D = new Array(x);

    for(var i = 0; i < array2D.length; i++)
    {
        array2D[i] = new Array(y);
    }

    return array2D;
}

var myNewArray = Array2D(4, 9);

myNewArray[3][5] = "booger";

Maybe this helps. You have to refer the @param

         /**       
         * Display a listing of the resource.
         *
         * @param  Illuminate\Http\Request $request
         * @return Response
         */
        public function index(Request $request)
        {
            if($request->ajax()){
                return "AJAX";
            }
            return "HTTP";
        }

What you want is this (actually the exact inverse of the currently accepted answer):

git checkout email
git merge --strategy-option=theirs staging  

What this does is:

• email branch files will now be exactly the same as staging branch
• email branch's history will be maintained
• staging branch's history will be added to email history

As added value, if you don't want all of staging branch's history, you can use squash to summarize it into a single commit message.

git checkout email
git merge --squash --strategy-option=theirs staging  
git commit -m "Single commit message for squash branch's history here'

So in summary, what this second version does is:

• email branch files will now be exactly the same as staging branch
• email branch's history will be maintained
• A single commit will be added on top of email branch's history. This commit will represent ALL the changes that took place in the staging branch

I am not sure why your solution did not work but the following code is working for me. Create a bezier mask and apply it to your view. In my code below I was rounding the bottom corners of the _backgroundView with a radius of 3 pixels. self is a custom UITableViewCell:

UIBezierPath *maskPath = [UIBezierPath
    bezierPathWithRoundedRect:self.backgroundImageView.bounds
    byRoundingCorners:(UIRectCornerBottomLeft | UIRectCornerBottomRight)
    cornerRadii:CGSizeMake(20, 20)
];

CAShapeLayer *maskLayer = [CAShapeLayer layer];

maskLayer.frame = self.bounds;
maskLayer.path = maskPath.CGPath;

self.backgroundImageView.layer.mask = maskLayer;

Swift version with some improvements:

let path = UIBezierPath(roundedRect:viewToRound.bounds, byRoundingCorners:[.TopRight, .BottomLeft], cornerRadii: CGSizeMake(20, 20))
let maskLayer = CAShapeLayer()

maskLayer.path = path.CGPath
viewToRound.layer.mask = maskLayer

Swift 3.0 version:

let path = UIBezierPath(roundedRect:viewToRound.bounds,
                        byRoundingCorners:[.topRight, .bottomLeft],
                        cornerRadii: CGSize(width: 20, height:  20))

let maskLayer = CAShapeLayer()

maskLayer.path = path.cgPath
viewToRound.layer.mask = maskLayer

Using requests and json makes it simple.

1. Call the API
2. Assuming the API returns a JSON, parse the JSON object into a Python dict using json.loads function
3. Loop through the dict to extract information.

Requests module provides you useful function to loop for success and failure.

if(Response.ok): will help help you determine if your API call is successful (Response code - 200)

Response.raise_for_status() will help you fetch the http code that is returned from the API.

Below is a sample code for making such API calls. Also can be found in github. The code assumes that the API makes use of digest authentication. You can either skip this or use other appropriate authentication modules to authenticate the client invoking the API.

#Python 2.7.6
#RestfulClient.py

import requests
from requests.auth import HTTPDigestAuth
import json

# Replace with the correct URL
url = "http://api_url"

# It is a good practice not to hardcode the credentials. So ask the user to enter credentials at runtime
myResponse = requests.get(url,auth=HTTPDigestAuth(raw_input("username: "), raw_input("Password: ")), verify=True)
#print (myResponse.status_code)

# For successful API call, response code will be 200 (OK)
if(myResponse.ok):

    # Loading the response data into a dict variable
    # json.loads takes in only binary or string variables so using content to fetch binary content
    # Loads (Load String) takes a Json file and converts into python data structure (dict or list, depending on JSON)
    jData = json.loads(myResponse.content)

    print("The response contains {0} properties".format(len(jData)))
    print("\n")
    for key in jData:
        print key + " : " + jData[key]
else:
  # If response code is not ok (200), print the resulting http error code with description
    myResponse.raise_for_status()

This works too and also demonstrates how to change the legend title:

ggplot(df, aes(x, y, colour=g)) +
  geom_line(stat="identity") + 
  theme(legend.position="bottom") +
  scale_color_discrete(name="")

The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:

A data frame of four rows:

df = pd.DataFrame({'A': [1,2,3,4]})

Now trying to assign a list/array of two elements to it:

df['B'] = [3,4]   # or df['B'] = np.array([3,4])

Both errors out:

ValueError: Length of values does not match length of index

Because the data frame has four rows but the list and array has only two elements.

Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:

df['B'] = pd.Series([3,4])

df
#   A     B
#0  1   3.0
#1  2   4.0
#2  3   NaN          # NaN because the value at index 2 and 3 doesn't exist in the Series
#3  4   NaN

For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:

df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))

#   A     B
#0  1   1.0
#1  2   5.0
#2  7   9.0
#3  8   NaN

The first is a list, the second is a tuple. Lists are mutable, tuples are not.

Take a look at the Data Structures section of the tutorial, and the Sequence Types section of the documentation.

The length function will do it. See http://www.techonthenet.com/oracle/functions/length.php

var item = "one,two,three";
var lastItem = item.split(",").pop();
console.log(lastItem); // three

I tried every solution above, but none of them worked for my problem. (I'm sure there are 1000 solutions to this problem) For my scenario, I was attempting to publish my WCF web service that I had in test into production.

However, I failed to realize that in production we are HTTPS only, meaning we redirect everything to HTTPS. As it turns out, I was pointing to the service via HTTP instead of HTTPS, thus causing the error. The solution in this scenario was to simply to change the address protocol to HTTPS rather than HTTP.

I hope that helps some poor soul out there trying to figure out this problem.

You could do something like:

globals()[class_name]

$('#test').attr('checked','checked');

$('#test').removeAttr('checked');

Here's the important part from the man page:

As the list of files/directories to transfer is built, rsync checks each name to be transferred against the list of include/exclude patterns in turn, and the first matching pattern is acted on: if it is an exclude pattern, then that file is skipped; if it is an include pattern then that filename is not skipped; if no matching pattern is found, then the filename is not skipped.

To summarize:

• Not matching any pattern means a file will be copied!
• The algorithm quits once any pattern matches

Also, something ending with a slash is matching directories (like find -type d would).

Let's pull apart this answer from above.

rsync -zarv  --prune-empty-dirs --include "*/"  --include="*.sh" --exclude="*" "$from" "$to"

1. Don't skip any directories
2. Don't skip any .sh files
3. Skip everything
4. (Implicitly, don't skip anything, but the rule above prevents the default rule from ever happening.)

Finally, the --prune-empty-directories keeps the first rule from making empty directories all over the place.

Alternatively to usleep(), which is not defined in POSIX 2008 (though it was defined up to POSIX 2004, and it is evidently available on Linux and other platforms with a history of POSIX compliance), the POSIX 2008 standard defines nanosleep():

nanosleep - high resolution sleep

#include <time.h>
int nanosleep(const struct timespec *rqtp, struct timespec *rmtp);

The nanosleep() function shall cause the current thread to be suspended from execution until either the time interval specified by the rqtp argument has elapsed or a signal is delivered to the calling thread, and its action is to invoke a signal-catching function or to terminate the process. The suspension time may be longer than requested because the argument value is rounded up to an integer multiple of the sleep resolution or because of the scheduling of other activity by the system. But, except for the case of being interrupted by a signal, the suspension time shall not be less than the time specified by rqtp, as measured by the system clock CLOCK_REALTIME.

The use of the nanosleep() function has no effect on the action or blockage of any signal.

It's not possible, sorry. If really needed, you could use a jQuery plugin to have a custom alert.

Performance wise, this should be comparable. Use Select statement and Sort to get a list and then pick the first or last (depending on your sort order).

var col = dt.Select("AccountLevel", "AccountLevel ASC");

var min = col.First();
var max = col.Last();

a = Array.new(Array.new(4))

0.upto(a.length-1) do |i|
  0.upto(a.length-1) do |j|
    a[i[j]] = 1
  end
end

0.upto(a.length-1) do |i|
  0.upto(a.length-1) do |j|
    print a[i[j]] = 1 #It's not a[i][j], but a[i[j]]
  end
  puts "\n"
end

You can check it easily using Java.lang.Class.getSimpleName() Method Only if variable has non-primitive type. It doesnt work with primitive types int ,long etc.

reference - Here is the Oracle docs link

There are a few things that could be happening here.

Is the dictionary you have listed the myDict? If so, then you don't have an object with a key of @"items", and the dict variable will be nil. You need to iterate through myDict directly.

Another thing to check is if _myArray is a valid instance of an NSMutableArray. If it's nil, the addObject: method will silently fail.

And a final thing to check is that the objects inside your dictionary are properly encased in NSNumbers (or some other non-primitive type).

Check this one out, too:

$(document).ready(function() { 
  if($("input:radio[name='yourRadioGroupName'][value='yourvalue']").is(":checked")) { 
      //its checked 
  } 
});

Try using RenderAction("myPartial","Account");

I just don't want the client to be able to change them under certain circumstances.

READONLY itself won't work. You may be able to do something funky w/CSS but we usually just make them disabled.

WARNING: If they're posted back then the client can change them, period. You can't rely on readonly to prevent a user from changing something. The could always use fiddler or just chane the html w/firebug or some such thing.

I've found the python inspect module to be very useful

For example with teststuff.py

import inspect

def dostuff():
    return __name__

DOSTUFF_SOURCE = inspect.getsource(dostuff)

if __name__ == "__main__":

    dostuff()

And from the another script or the python console

import teststuff

exec(DOSTUFF_SOURCE)

dostuff()

And now dostuff should be in the local scope and dostuff() will return the console or scripts _name_ whereas executing test.dostuff() will return the python modules name.

 1. Create the database

CREATE DATABASE db_name;

 2. Create the username for the database db_name

GRANT ALL PRIVILEGES ON db_name.* TO 'username'@'localhost' IDENTIFIED BY 'password';

 3. Use the database

USE db_name;

 4. Finally you are in database db_name and then execute the commands like create , select and insert operations.

Look into toFixed for Javascript numbers. You could write an onChange function for your number field that calls toFixed on the input and sets the new value.

Here I am checking session values(two values filled in text box on previous page)

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["sessUnit_code"] == null || Session["sessgrcSerial"] == null)
    {
        Response.Write("<Script Language = 'JavaScript'> alert('Go to GRC Tab and fill Unit Code and GRC Serial number first')</script>");
    }
    else
    {

        lblUnit.Text = Session["sessUnit_code"].ToString();
        LblGrcSr.Text = Session["sessgrcSerial"].ToString();
    }
}

Set selection property to None, make sure tableView has 'Single Selection' set and use this method in tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell delegate method:

extension UITableViewCell {
    func setSelectionColor(isSelected: Bool, selectionColor: UIColor, nonSelectionColor: UIColor) {
        contentView.backgroundColor = isSelected ? selectionColor : nonSelectionColor
    }
}

You can prefer quick-json parser to meet your requirement...

This is an old question, but I found the code useful and saved me three minutes of thinking :) So I am adding a small expansion to @opsb's answer.

If you wanted to convert this arc into a slice (to allow for fill) we can modify the code slightly:

function describeArc(x, y, radius, spread, startAngle, endAngle){_x000D_
    var innerStart = polarToCartesian(x, y, radius, endAngle);_x000D_
   var innerEnd = polarToCartesian(x, y, radius, startAngle);_x000D_
    var outerStart = polarToCartesian(x, y, radius + spread, endAngle);_x000D_
    var outerEnd = polarToCartesian(x, y, radius + spread, startAngle);_x000D_
_x000D_
    var largeArcFlag = endAngle - startAngle <= 180 ? "0" : "1";_x000D_
_x000D_
    var d = [_x000D_
        "M", outerStart.x, outerStart.y,_x000D_
        "A", radius + spread, radius + spread, 0, largeArcFlag, 0, outerEnd.x, outerEnd.y,_x000D_
        "L", innerEnd.x, innerEnd.y, _x000D_
        "A", radius, radius, 0, largeArcFlag, 1, innerStart.x, innerStart.y, _x000D_
        "L", outerStart.x, outerStart.y, "Z"_x000D_
    ].join(" ");_x000D_
_x000D_
    return d;_x000D_
}_x000D_
_x000D_
function polarToCartesian(centerX, centerY, radius, angleInDegrees) {_x000D_
  var angleInRadians = (angleInDegrees-90) * Math.PI / 180.0;_x000D_
_x000D_
  return {_x000D_
    x: centerX + (radius * Math.cos(angleInRadians)),_x000D_
    y: centerY + (radius * Math.sin(angleInRadians))_x000D_
  };_x000D_
}_x000D_
_x000D_
var path = describeArc(150, 150, 50, 30, 0, 50)_x000D_
document.getElementById("p").innerHTML = path_x000D_
document.getElementById("path").setAttribute('d',path)

<p id="p">_x000D_
</p>_x000D_
<svg width="300" height="300" style="border:1px gray solid">_x000D_
  <path id="path" fill="blue" stroke="cyan"></path>_x000D_
</svg>

and there you go!

This is for react-native, but login will work for all types.

isTokenExpired = async () => {
    try {
        const LoginTokenValue = await AsyncStorage.getItem('LoginTokenValue');
        if (JSON.parse(LoginTokenValue).RememberMe) {
            const { exp } = JwtDecode(LoginTokenValue);
            if (exp < (new Date().getTime() + 1) / 1000) {
                this.handleSetTimeout();
                return false;
            } else {
                //Navigate inside the application
                return true;
            }
        } else {
            //Navigate to the login page
        }
    } catch (err) {
        console.log('Spalsh -> isTokenExpired -> err', err);
        //Navigate to the login page
        return false;
    }
}

To undo git add, use:

git reset filename

You can pass multiple parameters as "?param1=value1&param2=value2"

But it's not secure. It's vulnerable to Cross Site Scripting (XSS) Attack.

Your parameter can be simply replaced with a script.

Have a look at this article and article

You can make it secure by using API of StringEscapeUtils

static String   escapeHtml(String str) 
          Escapes the characters in a String using HTML entities.

Even using https url for security without above precautions is not a good practice.

Have a look at related SE question:

Is URLEncoder.encode(string, "UTF-8") a poor validation?

Prototype Method

If you plan on getting a random value a lot, you might want to define a function for it.

First, put this in your code somewhere:

Array.prototype.sample = function(){
  return this[Math.floor(Math.random()*this.length)];
}

Now:

[1,2,3,4].sample() //=> a random element

To add to the answers here, ensure there's no space between the select and [name...

Wrong:

'select [name=' + name + ']'
       ^

Right:

'select[name=' + name + ']'

The solution seems to be to add multiple @font-face rules, for example:

@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans.ttf");
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Bold.ttf");
    font-weight: bold;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-Oblique.ttf");
    font-style: italic, oblique;
}
@font-face {
    font-family: "DejaVu Sans";
    src: url("fonts/DejaVuSans-BoldOblique.ttf");
    font-weight: bold;
    font-style: italic, oblique;
}

By the way, it would seem Google Chrome doesn't know about the format("ttf") argument, so you might want to skip that.

(This answer was correct for the CSS 2 specification. CSS3 only allows for one font-style rather than a comma-separated list.)

The Control class has HorizontalContentAlignment and VerticalContentAlignment properties. These properties determine how a control’s content fills the space within the control.
Set HorizontalContentAlignment and VerticalContentAlignment to Center.

To determine which radio button is checked, try this:

$('input:radio[name=theme]').click(function() {
  var val = $('input:radio[name=theme]:checked').val();
});

The event will be caught for all of the radio buttons in the group and the value of the selected button will be placed in val.

Update: After posting I decided that Paolo's answer above is better, since it uses one less DOM traversal. I am letting this answer stand since it shows how to get the selected element in a way that is cross-browser compatible.

you can use "__range" for example :

from datetime import datetime
start_date=datetime(2009, 12, 30)
end_end=datetime(2020,12,30)
Sample.objects.filter(date__range=[start_date,end_date])

This is how it would be done in a loop in C++(11):

   for (const auto& attack : m_attack)
    {  
        if (attack->m_num == input)
        {
            attack->makeDamage();
        }
    }

There is no for each in C++. Another option is to use std::for_each with a suitable functor (this could be anything that can be called with an Attack* as argument).

To make things even more clearer,

Registeration/Login direction ->

The password + salt is encrypted with a key generated from the: cost, salt and the password. we call that encrypted value the cipher text. then we attach the salt to this value and encoding it using base64. attaching the cost to it and this is the produced string from bcrypt:

$2a$COST$BASE64

This value is stored eventually.

What the attacker would need to do in order to find the password ? (other direction <- )

In case the attacker got control over the DB, the attacker will decode easily the base64 value, and then he will be able to see the salt. the salt is not secret. though it is random. Then he will need to decrypt the cipher text.

What is more important : There is no hashing in this process, rather CPU expensive encryption - decryption. thus rainbow tables are less relevant here.

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

You simply pass the FormControl an array of validators.

Here's an example showing how you can add validators to an existing FormControl:

this.form.controls["firstName"].setValidators([Validators.minLength(1), Validators.maxLength(30)]);

Note, this will reset any existing validators you added when you created the FormControl.

You can use scalar multiplication to modify each element in your vector.

> r <- 0:10 
> r <- r * 2
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

or

> r <- 0:10 * 2 
> r 
 [1]  0  2  4  6  8 10 12 14 16 18 20

You probably want a dict instead of separate variables. For example

d = {}
for i in range(3):
    d["group" + str(i)] = self.getGroup(selected, header+i)

If you insist on actually modifying local variables, you could use the locals function:

for i in range(3):
    locals()["group"+str(i)] = self.getGroup(selected, header+i)

On the other hand, if what you actually want is to modify instance variables of the class you're in, then you can use the setattr function

for i in group(3):
    setattr(self, "group"+str(i), self.getGroup(selected, header+i)

And of course, I'm assuming with all of these examples that you don't just want a list:

groups = [self.getGroup(i,header+i) for i in range(3)]

To parse a Date from a String you can choose which format you would like it to have. For example:

public Date StringToDate(String s){

    Date result = null;
    try{
        SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        result  = dateFormat.parse(s);
    }

    catch(ParseException e){
        e.printStackTrace();

    }
    return result ;
}

If you would like to use this method now, you will have to use something like this

Date date = StringToDate("2015-12-06 17:03:00");

For more explanation you should check out http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

$records = User::where('created_at' = CURDATE())->GET()); print($records);

I've tried all the solutions from the answers but couldn't get mysql command to work from the terminal, always getting the message

bash: command not found

The solution is to change the .bash_profile, and add the mysql path to .bash_profile

To do so follow these steps: 1. Open a new Terminal window or make sure you are in the home directory 2. Open .bash_profile using

nano .bash_profile

3. Add the following command to add the mysql path

PATH="/usr/local/mysql/bin:${PATH}"
export PATH

4. Press Ctrl+X, then press y and press enter.

The following is how my .bash_profile looks like

As Sanf0rd mentioned, Google launched the BottomNavigationView as part of the Design Support Library version 25.0.0. The limitations he mentioned are mostly true, except that you CAN change the background color of the view and even the text color and icon tint color. It also has an animation when you add more than 4 items (sadly it cannot be enabled or disabled manually).

I wrote a detailed tutorial about it with examples and an accompanying repository, which you can read here: https://blog.autsoft.hu/now-you-can-use-the-bottom-navigation-view-in-the-design-support-library/

The gist of it

You have to add these in your app level build.gradle:

compile 'com.android.support:appcompat-v7:25.0.0'  
compile 'com.android.support:design:25.0.0'

You can include it in your layout like this:

<android.support.design.widget.BottomNavigationView  
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/bottom_navigation_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:itemBackground="@color/darkGrey"
        app:itemIconTint="@color/bottom_navigation_item_background_colors"
        app:itemTextColor="@color/bottom_navigation_item_background_colors"
        app:menu="@menu/menu_bottom_navigation" />

You can specify the items via a menu resource like this:

<?xml version="1.0" encoding="utf-8"?>  
<menu  
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:id="@+id/action_one"
        android:icon="@android:drawable/ic_dialog_map"
        android:title="One"/>
    <item
        android:id="@+id/action_two"
        android:icon="@android:drawable/ic_dialog_info"
        android:title="Two"/>
    <item
        android:id="@+id/action_three"
        android:icon="@android:drawable/ic_dialog_email"
        android:title="Three"/>
    <item
        android:id="@+id/action_four"
        android:icon="@android:drawable/ic_popup_reminder"
        android:title="Four"/>
</menu>

And you can set the tint and text color as a color list, so the currently selected item is highlighted:

<?xml version="1.0" encoding="utf-8"?>  
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:color="@color/colorAccent"
        android:state_checked="false"/>
    <item
        android:color="@android:color/white"
        android:state_checked="true"/>

</selector>

Finally, you can handle the selection of the items with an OnNavigationItemSelectedListener:

bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {  
    @Override
    public boolean onNavigationItemSelected(@NonNull MenuItem item) {
        Fragment fragment = null;
        switch (item.getItemId()) {
            case R.id.action_one:
                // Switch to page one
                break;
            case R.id.action_two:
                // Switch to page two
                break;
            case R.id.action_three:
                // Switch to page three
                break;
        }
        return true;
    }
});

That should be what --link is for, at least for the hostname part.
With docker 1.10, and PR 19242, that would be:

docker network create --net-alias=[]: Add network-scoped alias for the container

(see last section below)

That is what Updating the /etc/hosts file details

In addition to the environment variables, Docker adds a host entry for the source container to the /etc/hosts file.

For instance, launch an LDAP server:

docker run -t  --name openldap -d -p 389:389 larrycai/openldap

And define an image to test that LDAP server:

FROM ubuntu
RUN apt-get -y install ldap-utils
RUN touch /root/.bash_aliases
RUN echo "alias lds='ldapsearch -H ldap://internalopenldap -LL -b
ou=Users,dc=openstack,dc=org -D cn=admin,dc=openstack,dc=org -w
password'" > /root/.bash_aliases
ENTRYPOINT bash

You can expose the 'openldap' container as 'internalopenldap' within the test image with --link:

 docker run -it --rm --name ldp --link openldap:internalopenldap ldaptest

Then, if you type 'lds', that alias will work:

ldapsearch -H ldap://internalopenldap ...

That would return people. Meaning internalopenldap is correctly reached from the ldaptest image.

Of course, docker 1.7 will add libnetwork, which provides a native Go implementation for connecting containers. See the blog post.
It introduced a more complete architecture, with the Container Network Model (CNM)

That will Update the Docker CLI with new “network” commands, and document how the “-net” flag is used to assign containers to networks.

docker 1.10 has a new section Network-scoped alias, now officially documented in network connect:

While links provide private name resolution that is localized within a container, the network-scoped alias provides a way for a container to be discovered by an alternate name by any other container within the scope of a particular network.
Unlike the link alias, which is defined by the consumer of a service, the network-scoped alias is defined by the container that is offering the service to the network.

Continuing with the above example, create another container in isolated_nw with a network alias.

$ docker run --net=isolated_nw -itd --name=container6 -alias app busybox
8ebe6767c1e0361f27433090060b33200aac054a68476c3be87ef4005eb1df17

--alias=[]         

Add network-scoped alias for the container

You can use --link option to link another container with a preferred alias

You can pause, restart, and stop containers that are connected to a network. Paused containers remain connected and can be revealed by a network inspect. When the container is stopped, it does not appear on the network until you restart it.

If specified, the container's IP address(es) is reapplied when a stopped container is restarted. If the IP address is no longer available, the container fails to start.

One way to guarantee that the IP address is available is to specify an --ip-range when creating the network, and choose the static IP address(es) from outside that range. This ensures that the IP address is not given to another container while this container is not on the network.

$ docker network create --subnet 172.20.0.0/16 --ip-range 172.20.240.0/20 multi-host-network

$ docker network connect --ip 172.20.128.2 multi-host-network container2
$ docker network connect --link container1:c1 multi-host-network container2

include the css file into your blade template in laravel

1. move css file into public->css folder in your laravel project.
2. use <link rel="stylesheet" href="{{ asset('css/filename') }}">

so css is applied in a blade.php file.

I've just had this same issue with Ionic.

It turns out nothing was wrong with my code, I simply had to quit the ionic serve session and run ionic serve again.

After going back into the app, my states worked fine.

I would also suggest pressing save on your app.js file a few times if you are running gulp, to make sure everything gets re-compiled.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

See this article for a longer discussion of named actions. It also shows that you can use the [HttpGet] attribute instead of prefixing the action name with "get".

http://www.asp.net/web-api/overview/web-api-routing-and-actions/routing-in-aspnet-web-api

Actually I'd bet this would be rather simple to achieve. It probably wouldn't operate or look exactly like what Apple has going on but could be very close.

First of all, you'd need to determine the CGRect of the UIView that you will be presenting. Once you've determine that you would just need to grab an image of the part of the UI so that it can be blurred. Something like this...

- (UIImage*)getBlurredImage {
    // You will want to calculate this in code based on the view you will be presenting.
    CGSize size = CGSizeMake(200,200);

    UIGraphicsBeginImageContext(size);
    [view drawViewHierarchyInRect:(CGRect){CGPointZero, w, h} afterScreenUpdates:YES]; // view is the view you are grabbing the screen shot of. The view that is to be blurred.
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    // Gaussian Blur
    image = [image applyLightEffect];

    // Box Blur
    // image = [image boxblurImageWithBlur:0.2f];

    return image;
}

Gaussian Blur - Recommended

Using the UIImage+ImageEffects Category Apple's provided here, you'll get a gaussian blur that looks very much like the blur in iOS 7.

Box Blur

You could also use a box blur using the following boxBlurImageWithBlur: UIImage category. This is based on an algorythem that you can find here.

@implementation UIImage (Blur)

-(UIImage *)boxblurImageWithBlur:(CGFloat)blur {
    if (blur < 0.f || blur > 1.f) {
        blur = 0.5f;
    }
    int boxSize = (int)(blur * 50);
    boxSize = boxSize - (boxSize % 2) + 1;

    CGImageRef img = self.CGImage;

    vImage_Buffer inBuffer, outBuffer;

    vImage_Error error;

    void *pixelBuffer;

    CGDataProviderRef inProvider = CGImageGetDataProvider(img);
    CFDataRef inBitmapData = CGDataProviderCopyData(inProvider);

    inBuffer.width = CGImageGetWidth(img);
    inBuffer.height = CGImageGetHeight(img);
    inBuffer.rowBytes = CGImageGetBytesPerRow(img);

    inBuffer.data = (void*)CFDataGetBytePtr(inBitmapData);

    pixelBuffer = malloc(CGImageGetBytesPerRow(img) * CGImageGetHeight(img));

    if(pixelBuffer == NULL)
        NSLog(@"No pixelbuffer");

    outBuffer.data = pixelBuffer;
    outBuffer.width = CGImageGetWidth(img);
    outBuffer.height = CGImageGetHeight(img);
    outBuffer.rowBytes = CGImageGetBytesPerRow(img);

    error = vImageBoxConvolve_ARGB8888(&inBuffer, &outBuffer, NULL, 0, 0, boxSize, boxSize, NULL, kvImageEdgeExtend);

    if (error) {
        NSLog(@"JFDepthView: error from convolution %ld", error);
    }

    CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
    CGContextRef ctx = CGBitmapContextCreate(outBuffer.data,
                                         outBuffer.width,
                                         outBuffer.height,
                                         8,
                                         outBuffer.rowBytes,
                                         colorSpace,
                                         kCGImageAlphaNoneSkipLast);
    CGImageRef imageRef = CGBitmapContextCreateImage (ctx);
    UIImage *returnImage = [UIImage imageWithCGImage:imageRef];

    //clean up
    CGContextRelease(ctx);
    CGColorSpaceRelease(colorSpace);

    free(pixelBuffer);
    CFRelease(inBitmapData);

    CGImageRelease(imageRef);

    return returnImage;
}

@end

Now that you are calculating the screen area to blur, passing it into the blur category and receiving a UIImage back that has been blurred, now all that is left is to set that blurred image as the background of the view you will be presenting. Like I said, this will not be a perfect match for what Apple is doing, but it should still look pretty cool.

Hope it helps.

This is kind of hacky, but it works.

I used JavascriptExecutor and added a div to the HTML, and changed the text in the div to $('#prettyTime').val() I then used Selenium to retrieve the div and grab its value. After testing the correctness of the value, I removed the div that was just created.

Use OutputDebugString instead of afxDump.

Example:

#define _TRACE_MAXLEN 500

#if _MSC_VER >= 1900
#define _PRINT_DEBUG_STRING(text) OutputDebugString(text)
#else // _MSC_VER >= 1900
#define _PRINT_DEBUG_STRING(text) afxDump << text
#endif // _MSC_VER >= 1900

void MyTrace(LPCTSTR sFormat, ...)
{
    TCHAR text[_TRACE_MAXLEN + 1];
    memset(text, 0, _TRACE_MAXLEN + 1);
    va_list args;
    va_start(args, sFormat);
    int n = _vsntprintf(text, _TRACE_MAXLEN, sFormat, args);
    va_end(args);
    _PRINT_DEBUG_STRING(text);
    if(n <= 0)
        _PRINT_DEBUG_STRING(_T("[...]"));
}

You're confusing actual precision and display precision. Decimal rounding cannot be represented exactly in binary. You should try:

> np.set_printoptions(precision=2)
> np.array([5.333333])
array([ 5.33])

This is answer based on answer from iraSenthil but with annotation (Captor). In my opinion it has some advantages:

• it's shorter
• it's easier to read
• it can handle generics without warnings

Example:

@RunWith(MockitoJUnitRunner.class)
public class SomeTest{

    @Captor
    private ArgumentCaptor<List<SomeType>> captor;

    //...

    @Test 
    public void shouldTestArgsVals() {
        //...
        verify(mockedObject).someMethodOnMockedObject(captor.capture());

        assertThat(captor.getValue().getXXX(), is("expected"));
    }
}

Right click on the project in solution-explorer and click "clean".

Now run F5

Make sure the code is as below:

Console.WriteLine("TEST");
Console.ReadLine();

Swift 4

    let calendar = Calendar.current
    let time=calendar.dateComponents([.hour,.minute,.second], from: Date())
    print("\(time.hour!):\(time.minute!):\(time.second!)")

Original answer Nov 20 '15:

No option for a specific tag as of Today. Docker compose just does its magic and assigns a tag like you are seeing. You can always have some script call docker tag <image> <tag> after you call docker-compose.

Now there's an option as described above or here

build: ./dir
image: webapp:tag

Updated for Swift 3 and above:

//1. Create the alert controller.
let alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .alert)

//2. Add the text field. You can configure it however you need.
alert.addTextField { (textField) in
    textField.text = "Some default text"
}

// 3. Grab the value from the text field, and print it when the user clicks OK.
alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { [weak alert] (_) in
    let textField = alert.textFields![0] // Force unwrapping because we know it exists.
    print("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.present(alert, animated: true, completion: nil)

Swift 2.x

Assuming you want an action alert on iOS:

//1. Create the alert controller.            
var alert = UIAlertController(title: "Some Title", message: "Enter a text", preferredStyle: .Alert)

//2. Add the text field. You can configure it however you need.
alert.addTextFieldWithConfigurationHandler({ (textField) -> Void in
    textField.text = "Some default text."
})

//3. Grab the value from the text field, and print it when the user clicks OK. 
alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: { [weak alert] (action) -> Void in
    let textField = alert.textFields![0] as UITextField
    println("Text field: \(textField.text)")
}))

// 4. Present the alert.
self.presentViewController(alert, animated: true, completion: nil)

You can use

insert into table_name
(date_field)
values
(TO_DATE('2003/05/03 21:02:44', 'yyyy/mm/dd hh24:mi:ss'));

Hope it helps.

CSS:

#block_container
{
    text-align:center;
}
#bloc1, #bloc2
{
    display:inline;
}

HTML

<div id="block_container">

    <div id="bloc1"><?php echo " version ".$version." Copyright &copy; All Rights Reserved."; ?></div>  
    <div id="bloc2"><img src="..."></div>

</div>

Also, you shouldn't put raw content into <div>'s, use an appropriate tag such as <p> or <span>.

Edit: Here is a jsFiddle demo.

Depending on the environment you're wanting to do this in, it is possible by using the Excel Interop. It's quite a mess dealing with COM however and ensuring you clear up resources else Excel instances stay hanging around on your machine.

Checkout this MSDN Example if you want to learn more.

Depending on your format you could produce CSV or SpreadsheetML yourself, thats not too hard. Other alternatives are to use 3rd party libraries to do it. Obviously they cost money though.

set background color to the layout or view

To modify the float output do this:

df= pd.DataFrame(range(5), columns=['a'])
df.a = df.a.astype(float)
df

Out[33]:

Question 1: How do create a DataTable in C#?

Answer 1:

DataTable dt = new DataTable(); // DataTable created

// Add columns in your DataTable
dt.Columns.Add("Name");
dt.Columns.Add("Marks");

Note: There is no need to Clear() the DataTable after creating it.

Question 2: How to add row(s)?

Answer 2: Add one row:

dt.Rows.Add("Ravi","500");

Add multiple rows: use ForEach loop

DataTable dt2 = (DataTable)Session["CartData"]; // This DataTable contains multiple records
foreach (DataRow dr in dt2.Rows)
{
    dt.Rows.Add(dr["Name"], dr["Marks"]);
}

This solution is only for components

If we toggle(show/hide) components using booleans then data is also removed. No need to clean the form fields.

I usually make components and initialize them using booleans. e.g.

<template>
    <button @click="show_create_form = true">Add New Record</button
    <create-form v-if="show_create_form" />
</template>


<script>
...
data(){
   return{
       show_create_form:false //making it false by default
   }
},
methods:{
    submitForm(){
      //...
      this.axios.post('/submit-form-url',data,config)
           .then((response) => {
               this.show_create_form= false; //hide it again after success.
               //if you now click on add new record button then it will show you empty form
           }).catch((error) => {
              //
           })
    }
}
...
</script>

When use clicks on edit button then this boolean becomes true and after successful submit I change it to false again.

If you are using PyQt, then for normal work, you should add "shell":"true" value, this looks like:

{
  "cmd": ["c:/Python32/python.exe", "-u", "$file"],
  "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
  "selector": "source.python",
  "shell":"true"
}

Hash tables have higher constants than common map implementations, which become significant for small containers. Max size is 10, 100, or maybe even 1,000 or more? Constants are the same as ever, but O(log n) is close to O(k). (Remember logarithmic complexity is still really good.)

What makes a good hash function depends on your data's characteristics; so if I don't plan on looking at a custom hash function (but can certainly change my mind later, and easily since I typedef damn near everything) and even though defaults are chosen to perform decently for many data sources, I find the ordered nature of map to be enough of a help initially that I still default to map rather than a hash table in that case.

Plus that way you don't have to even think about writing a hash function for other (usually UDT) types, and just write op< (which you want anyway).

You can try:

WebElement getmenu= driver.findElement(By.xpath("//*[@id='ui-id-2']/span[2]")); //xpath the parent

Actions act = new Actions(driver);
act.moveToElement(getmenu).perform();

Thread.sleep(3000);
WebElement clickElement= driver.findElement(By.linkText("Sofa L"));//xpath the child
act.moveToElement(clickElement).click().perform();

If you had case the web have many category, use the first method. For menu you wanted, you just need the second method.

Try two things:

1. Set in $ORACLE_HOME/network/admin/tnsnames.ora on the oracle server server=dedicated to server=shared to allow more than one connection at a time. Restart oracle.
2. If you are using Java this might help you: In java/jdk1.6.0_31/jre/lib/security/Java.security change securerandom.source=file:/dev/urandom to securerandom.source=file:///dev/urandom

You can run your file in http-server.

1> Have Node.js installed in your system.

2> In CMD, run the command npm install http-server -g

3> Navigate to the specific path of your file folder in CMD and run the command http-server

Thanks:)

I just input some value that I knew was invalid and here is the output:

'whatToInput' is not a supported event for HtmlPanelGrid. Please specify one of these supported event names: click, dblclick, keydown, keypress, keyup, mousedown, mousemove, mouseout, mouseover, mouseup.

So values you can pass to event are

• click
• dblclick
• keydown
• mousedown
• mousemove
• mouseover
• mouseup

A fine example found here. Powerlord got it right, below, for POST you need HttpURLConnection, instead.

Below is the code to do that,

    URL url = new URL(urlString);
    URLConnection conn = url.openConnection();
    conn.setDoOutput(true);
    conn.setRequestProperty ("Authorization", encodedCredentials);

    OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

    writer.write(data);
    writer.flush();
    String line;
    BufferedReader reader = new BufferedReader(new 
                                     InputStreamReader(conn.getInputStream()));
    while ((line = reader.readLine()) != null) {
      System.out.println(line);
    }
    writer.close();
    reader.close();

Change URLConnection to HttpURLConnection, to make it POST request.

    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setRequestMethod("POST");

Suggestion (...in comments):

You might need to set these properties too,

conn.setRequestProperty( "Content-type", "application/x-www-form-urlencoded");
conn.setRequestProperty( "Accept", "*/*" );

If you don't have bs-config.json, you can change the port inside the lite-server module. Go to node_modules/lite-server/lib/config-defaults.js in your project, then add the port in "modules.export" like this.

module.export {
    port :8000, // to any available port
    ...
}

Then you can restart the server.

A solution without java reflection DataLine.Info info = new DataLine.Info(SourceDataLine.class, audioFormat)

Java reflection decrease performance. to run: java playsound absoluteFilePathTo/file.wav

import javax.sound.sampled.*;
import java.io.*;
public class playsound {

    public static void main (String args[]) throws Exception {
        playSound (args[0]);
    }

I already had running postgres on host machine and didn't want to allow connections from network, so I did run temporary postgres instance in container and created database in just two lines:

# Run PostgreSQL
docker run --name postgres-container -e POSTGRES_PASSWORD=password -it -p 5433:5432 postgres

# Create database
docker exec -it postgres-container createdb -U postgres my-db

In Robins's answer ends-with is not supported in xpath 1.0 too.. Only starts-with is supported... So if your condition is not very specific..You can Use like this which worked for me

//*[starts-with(@id,'sometext') and contains(@name,'_text')]`\

Install Certificates.command on your mac.

Java 8 Comparator interface has a reversed method : https://docs.oracle.com/javase/8/docs/api/java/util/Comparator.html#reversed--

You can just inject the DOCUMENT token into the constructor and use the same functions on it

import { Inject }  from '@angular/core';
import { DOCUMENT } from '@angular/common'; 

@Component({...})
export class AppCmp {
   constructor(@Inject(DOCUMENT) document) {
      document.getElementById('el');
   }
}

Or if the element you want to get is in that component, you can use template references.

For example, it works with Curl, Apache and PHP.

PHP file:

<?php
echo $_SERVER['REQUEST_METHOD'] . PHP_EOL;
echo file_get_contents('php://input') . PHP_EOL;

Console command:

$ curl -X GET -H "Content-Type: application/json" -d '{"the": "body"}' 'http://localhost/test/get.php'

Output:

GET
{"the": "body"}

You can just use:

> names(LIST)
[1] "A" "B"

Obviously the names of the first element is just

> names(LIST)[1]
[1] "A"

I found the following was a better solution depending on the content of your left, center and right items. A width of 100% without a margin caused overlapping of divs and was preventing anchor tags to work correctly - that is without the messy use of z-indexes.

.navbar-brand
{
    position: absolute;
    width: 100%;
    left: 0;
    margin: auto;
    margin-left: 48%;
}

It's an if statement all on one line.

So

var x=1;
(x == 1) ? y="true" : y="false";
alert(y);

The expression to be evaluated is in the ( )

If it matches true, execute the code after the ?

If it matches false, execute the code after the :

You are looking for the CASE statement

http://msdn.microsoft.com/en-us/library/ms181765.aspx

Example copied from MSDN:

USE AdventureWorks;
GO
SELECT   ProductNumber, Category =
      CASE ProductLine
         WHEN 'R' THEN 'Road'
         WHEN 'M' THEN 'Mountain'
         WHEN 'T' THEN 'Touring'
         WHEN 'S' THEN 'Other sale items'
         ELSE 'Not for sale'
      END,
   Name
FROM Production.Product
ORDER BY ProductNumber;
GO

If you are limited to ES6, the best option is Promise all. Promise.all(array) also returns an array of promises after successfully executing all the promises in array argument. Suppose, if you want to update many student records in the database, the following code demonstrates the concept of Promise.all in such case-

let promises = students.map((student, index) => {
//where students is a db object
student.rollNo = index + 1;
student.city = 'City Name';
//Update whatever information on student you want
return student.save();
});
Promise.all(promises).then(() => {
  //All the save queries will be executed when .then is executed
  //You can do further operations here after as all update operations are completed now
});

Map is just an example method for loop. You can also use for or forin or forEach loop. So the concept is pretty simple, start the loop in which you want to do bulk async operations. Push every such async operation statement in an array declared outside the scope of that loop. After the loop completes, execute the Promise all statement with the prepared array of such queries/promises as argument.

The basic concept is that the javascript loop is synchronous whereas database call is async and we use push method in loop that is also sync. So, the problem of asynchronous behavior doesn't occur inside the loop.

There are two options. The first (and better) one is using the Fetch as Google option in Webmaster Tools that Mike Flynn commented about. Here are detailed instructions:

1. Go to: https://www.google.com/webmasters/tools/ and log in
2. If you haven't already, add and verify the site with the "Add a Site" button
3. Click on the site name for the one you want to manage
4. Click Crawl -> Fetch as Google
5. Optional: if you want to do a specific page only, type in the URL
6. Click Fetch
7. Click Submit to Index
8. Select either "URL" or "URL and its direct links"
9. Click OK and you're done.

With the option above, as long as every page can be reached from some link on the initial page or a page that it links to, Google should recrawl the whole thing. If you want to explicitly tell it a list of pages to crawl on the domain, you can follow the directions to submit a sitemap.

Your second (and generally slower) option is, as seanbreeden pointed out, submitting here: http://www.google.com/addurl/

Update 2019:

1. Login to - Google Search Console
2. Add a site and verify it with the available methods.
3. After verification from the console, click on URL Inspection.
4. In the Search bar on top, enter your website URL or custom URLs for inspection and enter.
5. After Inspection, it'll show an option to Request Indexing
6. Click on it and GoogleBot will add your website in a Queue for crawling.

// Get the focused element:
var $focused = $(':focus');

// No jQuery:
var focused = document.activeElement;

// Does the element have focus:
var hasFocus = $('foo').is(':focus');

// No jQuery:
elem === elem.ownerDocument.activeElement;

Which one should you use? quoting the jQuery docs:

As with other pseudo-class selectors (those that begin with a ":"), it is recommended to precede :focus with a tag name or some other selector; otherwise, the universal selector ("*") is implied. In other words, the bare $(':focus') is equivalent to $('*:focus'). If you are looking for the currently focused element, $( document.activeElement ) will retrieve it without having to search the whole DOM tree.

The answer is:

document.activeElement

And if you want a jQuery object wrapping the element:

$(document.activeElement)

I need to select every production with a category that doesn't contain "Business"

Although I upvoted @Arran's answer as correct, I would also add this... Strictly interpreted, the OP's specification would be implemented as

//production[category[not(contains(., 'Business'))]]

rather than

//production[not(contains(category, 'Business'))]

The latter selects every production whose first category child doesn't contain "Business". The two XPath expressions will behave differently when a production has no category children, or more than one.

It doesn't make any difference in practice as long as every <production> has exactly one <category> child, as in your short example XML. Whether you can always count on that being true or not, depends on various factors, such as whether you have a schema that enforces that constraint. Personally, I would go for the more robust option, since it doesn't "cost" much... assuming your requirement as stated in the question is really correct (as opposed to e.g. 'select every production that doesn't have a category that contains "Business"').

char* c = new char[length]();

For Visual Studio Code

Got to this question because I was looking for a way to select multiple words with mouse click on VS Code, which should be achieved by using alt+click, but this keybinding wasn't working (I think it is something related to my OS, Ubuntu).

For anyone looking for something similar, try changing the key to ctrl+click.

Go to Selection > Switch to Ctrl+Click for Multi Cursor

 import java.util.ArrayList;
 import java.util.Iterator;


 public class javaClass {

public static void main(String args[]) {


    ArrayList<String> alstr = new ArrayList<>();
    alstr.add("irfan");
    alstr.add("yogesh");
    alstr.add("kapil");

Same basic solution as others, but I personally prefer to use map instead of the list comprehension:

>>> L = [104, 101, 108, 108, 111, 44, 32, 119, 111, 114, 108, 100]
>>> ''.join(map(chr,L))
'hello, world'

You could create a class Dictionary so you can interact with the Dictionary list easily:

class Dictionary {_x000D_
  constructor() {_x000D_
    this.items = {};_x000D_
  }_x000D_
  has(key) {_x000D_
    return key in this.items;_x000D_
  }_x000D_
  set(key,value) {_x000D_
    this.items[key] = value;_x000D_
  }_x000D_
  delete(key) {_x000D_
    if( this.has(key) ){_x000D_
      delete this.items[key]_x000D_
      return true;_x000D_
    }_x000D_
    return false;_x000D_
  }_x000D_
}_x000D_
_x000D_
var d = new Dictionary();_x000D_
d.set(1, "value1")_x000D_
d.set(2, "value2")_x000D_
d.set(3, "value3")_x000D_
console.log(d.has(2));_x000D_
d.delete(2);_x000D_
console.log(d.has(2));

I had Node.js 6.x installed and wanted to install Node.js 8.x.

Here's the commands I used (taken from Nodejs's site with a few extra steps to handle the yum cached data):

1. sudo yum remove nodejs: Uninstall Node.js 6.x (I don't know if this was necessary or not)
2. curl --silent --location https://rpm.nodesource.com/setup_8.x | sudo bash -
3. sudo yum clean all
4. sudo yum makecache: Regenerate metadata cache (this wasn't in the docs, but yum kept trying to install Node.jx 6.x, unsuccessfully, until I issued these last two commands)
5. sudo yum install nodejs: Install Node.js 8.x

You can add other repo first as a remote to your current repo:

git remote add other_name PATH_TO_OTHER_REPO

then fetch brach from that remote:

git fetch other_name branch_name:branch_name

this creates that branch as a new branch in your current repo, then you can diff that branch with any of your branches, for example, to compare current branch against new branch(branch_name):

git diff branch_name

If you want a strongly typed list of anonymous types, you'll need to make the list an anonymous type too. The easiest way to do this is to project a sequence such as an array into a list, e.g.

var nodes = (new[] { new { Checked = false, /* etc */ } }).ToList();

Then you'll be able to access it like:

nodes.Any(n => n.Checked);

Because of the way the compiler works, the following then should also work once you have created the list, because the anonymous types have the same structure so they are also the same type. I don't have a compiler to hand to verify this though.

nodes.Add(new { Checked = false, /* etc */ });

Just in case you want to store the selected values in single column seperated by , then you can use below approach

string selectedItems = String.Join(",", CBLGold.Items.OfType<ListItem>().Where(r => r.Selected).Select(r => r.Value));

if you want to store Text not values then Change the r.Value to r.Text

Default behaviour of PowerShell is just to dump everything that falls out of a pipeline without being picked up by another pipeline element or being assigned to a variable (or redirected) into Out-Host. What Out-Host does is obviously host-dependent.

Just letting things fall out of the pipeline is not a substitute for Write-Host which exists for the sole reason of outputting text in the host application.

If you want output, then use the Write-* cmdlets. If you want return values from a function, then just dump the objects there without any cmdlet.
