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

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

You can't return because you're not in a function. You can exit though.

import sys
sys.exit(0)

0 (the default) means success, non-zero means failure.

This worked for me - if you have to log in Application_Start, do it before you modify the context. You will get a log entry, just with no source, like:

2019-03-12 09:35:43,659 INFO (null) - Application Started

I generally log both the Application_Start and Session_Start, so I see more detail in the next message

2019-03-12 09:35:45,064 INFO ~/Leads/Leads.aspx - Session Started (Local)

        protected void Application_Start(object sender, EventArgs e)
        {
            log4net.Config.XmlConfigurator.Configure();
            log.Info("Application Started");
            GlobalContext.Properties["page"] = new GetCurrentPage();
        }

        protected void Session_Start(object sender, EventArgs e)
        {
            Globals._Environment = WebAppConfig.getEnvironment(Request.Url.AbsoluteUri, Properties.Settings.Default.LocalOverride);
            log.Info(string.Format("Session Started ({0})", Globals._Environment));
        }

Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). Here's a version that's just a teeny bit cleaned up and which prints "kyle boon" as the decoded string:

import java.security.MessageDigest;
import java.util.Arrays;

import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class TripleDESTest {

    public static void main(String[] args) throws Exception {

        String text = "kyle boon";

        byte[] codedtext = new TripleDESTest().encrypt(text);
        String decodedtext = new TripleDESTest().decrypt(codedtext);

        System.out.println(codedtext); // this is a byte array, you'll just see a reference to an array
        System.out.println(decodedtext); // This correctly shows "kyle boon"
    }

    public byte[] encrypt(String message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);

        final byte[] plainTextBytes = message.getBytes("utf-8");
        final byte[] cipherText = cipher.doFinal(plainTextBytes);
        // final String encodedCipherText = new sun.misc.BASE64Encoder()
        // .encode(cipherText);

        return cipherText;
    }

    public String decrypt(byte[] message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        decipher.init(Cipher.DECRYPT_MODE, key, iv);

        // final byte[] encData = new
        // sun.misc.BASE64Decoder().decodeBuffer(message);
        final byte[] plainText = decipher.doFinal(message);

        return new String(plainText, "UTF-8");
    }
}

use sth like

<input type="text" name="yourName" placeholder="A new value" />

You can do that in your app.config. like that:

maxReceivedMessageSize="2147483647" 

(The max value is Int32.MaxValue )

Or in Code:

WSHttpBinding binding = new WSHttpBinding();
binding.Name = "MyBinding";
binding.MaxReceivedMessageSize = Int32.MaxValue;

Note:

If your service is open to the Wide world, think about security when you increase this value.

I solved this by adding below code to tsconfig.json file.

"lib": [
    "ES5",
    "ES2015",
    "DOM",
    "ScriptHost"]

JPA specification contains a very precise description of semantics of these operations, better than in javadoc:

The semantics of the persist operation, applied to an entity X are as follows:

• If X is a new entity, it becomes managed. The entity X will be entered into the database at or before transaction commit or as a result of the flush operation.

• If X is a preexisting managed entity, it is ignored by the persist operation. However, the persist operation is cascaded to entities referenced by X, if the relationships from X to these other entities are annotated with the cascade=PERSIST or cascade=ALL annotation element value or specified with the equivalent XML descriptor element.

• If X is a removed entity, it becomes managed.

• If X is a detached object, the EntityExistsException may be thrown when the persist operation is invoked, or the EntityExistsException or another PersistenceException may be thrown at flush or commit time.

• For all entities Y referenced by a relationship from X, if the relationship to Y has been annotated with the cascade element value cascade=PERSIST or cascade=ALL, the persist operation is applied to Y.

The semantics of the merge operation applied to an entity X are as follows:

• If X is a detached entity, the state of X is copied onto a pre-existing managed entity instance X' of the same identity or a new managed copy X' of X is created.

• If X is a new entity instance, a new managed entity instance X' is created and the state of X is copied into the new managed entity instance X'.

• If X is a removed entity instance, an IllegalArgumentException will be thrown by the merge operation (or the transaction commit will fail).

• If X is a managed entity, it is ignored by the merge operation, however, the merge operation is cascaded to entities referenced by relationships from X if these relationships have been annotated with the cascade element value cascade=MERGE or cascade=ALL annotation.

• For all entities Y referenced by relationships from X having the cascade element value cascade=MERGE or cascade=ALL, Y is merged recursively as Y'. For all such Y referenced by X, X' is set to reference Y'. (Note that if X is managed then X is the same object as X'.)

• If X is an entity merged to X', with a reference to another entity Y, where cascade=MERGE or cascade=ALL is not specified, then navigation of the same association from X' yields a reference to a managed object Y' with the same persistent identity as Y.

To just return a list containing the most common words:

from collections import Counter
words=["i", "love", "you", "i", "you", "a", "are", "you", "you", "fine", "green"]
most_common_words= [word for word, word_count in Counter(words).most_common(3)]
print most_common_words

this prints:

['you', 'i', 'a']

the 3 in "most_common(3)", specifies the number of items to print. Counter(words).most_common() returns a a list of tuples with each tuple having the word as the first member and the frequency as the second member.The tuples are ordered by the frequency of the word.

`most_common = [item for item in Counter(words).most_common()]
print(str(most_common))
[('you', 4), ('i', 2), ('a', 1), ('are', 1), ('green', 1), ('love',1), ('fine', 1)]`

"the word for word, word_counter in", extracts only the first member of the tuple.

Try this:

$('#ddlCodes').change(function() {
  var option = this.options[this.selectedIndex];
  $('#txtEntry2').text($(option).text());
});

Dependency Injection

If you inject the Bar instance, or a factory that is used for creating the Bar instance (or one of the other 483 ways of doing this), you'd have the access necessary to do perform the test.

Factory Example:

Given a Foo class written like this:

public class Foo {
  private BarFactory barFactory;

  public Foo(BarFactory factory) {
    this.barFactory = factory;
  }

  public void foo() {
    Bar bar = this.barFactory.createBar();
    bar.someMethod();
  }
}

in your test method you can inject a BarFactory like this:

@Test
public void testDoFoo() {
  Bar bar = mock(Bar.class);
  BarFactory myFactory = new BarFactory() {
    public Bar createBar() { return bar;}
  };

  Foo foo = new Foo(myFactory);
  foo.foo();

  verify(bar, times(1)).someMethod();
}

Bonus: This is an example of how TDD can drive the design of your code.

function isNumber(n) {
  return !isNaN(parseFloat(n)) && isFinite(n);
}

NaN means "Not a number." It's a special floating point value that means that the result of an operation was not defined or not representable as a real number.

See here for more explanation of this value.

As zendar wrote, it is nice to use the Socket.Poll and Socket.Available, but you need to take into consideration that the socket might not have been initialized in the first place. This is the last (I believe) piece of information and it is supplied by the Socket.Connected property. The revised version of the method would looks something like this:

 static bool IsSocketConnected(Socket s)
    {
        return !((s.Poll(1000, SelectMode.SelectRead) && (s.Available == 0)) || !s.Connected);

/* The long, but simpler-to-understand version:

        bool part1 = s.Poll(1000, SelectMode.SelectRead);
        bool part2 = (s.Available == 0);
        if ((part1 && part2 ) || !s.Connected)
            return false;
        else
            return true;

*/
    }

Try docker volume create.

mkdir -p /data1/Downloads
docker volume create --driver local --name hello --opt type=none --opt device=/data1/Downloads --opt o=uid=root,gid=root --opt o=bind
docker run -i -v hello:/Downloads ubuntu bash

Take a look at the document https://docs.docker.com/engine/reference/commandline/volume_create/

If mongodb is installed via Homebrew the default location is:

/usr/local/var/mongodb

See the answer from @simonbogarde for the location of other interesting files that are different when using Homebrew.

Here's what the JDK API says about AbstractMethodError:

Thrown when an application tries to call an abstract method. Normally, this error is caught by the compiler; this error can only occur at run time if the definition of some class has incompatibly changed since the currently executing method was last compiled.

Bug in the oracle driver, maybe?

I had the same problem and solved it by applying several things. The first, if it is a program that you did with Qt.

In the folder (in my case) of "C: \ Qt \ Qt5.10.0 \ 5.10.0 \ msvc2017_64 \ plugins" you find other folders, one of them is "platforms". That "platforms" folder is going to be copied next to your .exe executable. Now, if you get the error 0xc000007d is that you did not copy the version that was, since it can be 32bits or 64.

If you continue with the errors is that you lack more libraries. With the "Dependency Walker" program you can detect some of the missing folders. Surely it will indicate to you that you need an NVIDIA .dll, and it tells you the location.

Another way, instead of using "Dependency Walker" is to copy all the .dll from your "C: \ Windows \ System32" folder next to your executable file. Execute your .exe and if everything loads well, so you do not have space occupied in dll libraries that you do not need or use, use the .exe program with all your options and without closing the .exe you do is erase all the .dll that you just copied next to the .exe, so if those .dll are being used by your program, the system will not let you erase, only removing those that are not necessary.

I hope this solution serves you.

Remember that if your operating system is 64 bits, the libraries will be in the System32 folder, and if your operating system is 32 bits, they will also be in the System32 folder. This happens so that there are no compatibility problems with programs that are 32 bits in a 64-bit computer. The SysWOW64 folder contains the 32-bit files as a backup.

I wanted a one-time solution:

ssh -o ServerAliveInterval=60 [email protected]

Stored it in an alias:

alias sshprod='ssh -v -o ServerAliveInterval=60 [email protected]'

Now can connect like this:

me@MyMachine:~$ sshprod

<body>
    <div style=" display: table; margin: 250 auto;">
        In center
    </div>
</body>

If you want to change the vertical position, change the value of 250 and you can arrange the content as per your need. There is no need to give the width and other parameters.

To answer your first question, the way you load a module is depending on the module entry point and the main parameter of the package.json.

Let's say you have the following file structure:

my-npm-module
|-- lib
|   |-- module.js
|-- package.json

Without main parameter in the package.json, you have to load the module by giving the module entry point: require('my-npm-module/lib/module.js').

If you set the package.json main parameter as follows "main": "lib/module.js", you will be able to load the module this way: require('my-npm-module').

I think one of the original questions here was not answered. I believe that vanilla eval() is not used because then angular apps would not work as Chrome apps, which explicitly prevent eval() from being used for security reasons.

In XML, use:

android:background="@android:color/transparent"

You can use curl to update php version.

curl -s http://php-osx.liip.ch/install.sh | bash -s 7.3

Last Step:

export PATH=/usr/local/php5/bin:$PATH

Check the upgraded version

php -v

This does exist, but it's actually a feature of git log:

git log -p [--follow] [-1] <path>

Note that -p can also be used to show the inline diff from a single commit:

git log -p -1 <commit>

Options used:

• -p (also -u or --patch) is hidden deeeeeeeep in the git-log man page, and is actually a display option for git-diff. When used with log, it shows the patch that would be generated for each commit, along with the commit information—and hides commits that do not touch the specified <path>. (This behavior is described in the paragraph on --full-diff, which causes the full diff of each commit to be shown.)
• -1 shows just the most recent change to the specified file (-n 1 can be used instead of -1); otherwise, all non-zero diffs of that file are shown.
• --follow is required to see changes that occurred prior to a rename.

As far as I can tell, this is the only way to immediately see the last set of changes made to a file without using git log (or similar) to either count the number of intervening revisions or determine the hash of the commit.

To see older revisions changes, just scroll through the log, or specify a commit or tag from which to start the log. (Of course, specifying a commit or tag returns you to the original problem of figuring out what the correct commit or tag is.)

Credit where credit is due:

• I discovered log -p thanks to this answer.
• Credit to FranciscoPuga and this answer for showing me the --follow option.
• Credit to ChrisBetti for mentioning the -n 1 option and atatko for mentioning the -1 variant.
• Credit to sweaver2112 for getting me to actually read the documentation and figure out what -p "means" semantically.

A solution faster than using set() that works on sequences (not iterables) is to simply count the first element. This assumes the list is non-empty (but that's trivial to check, and decide yourself what the outcome should be on an empty list)

x.count(x[0]) == len(x)

some simple benchmarks:

>>> timeit.timeit('len(set(s1))<=1', 's1=[1]*5000', number=10000)
1.4383411407470703
>>> timeit.timeit('len(set(s1))<=1', 's1=[1]*4999+[2]', number=10000)
1.4765670299530029
>>> timeit.timeit('s1.count(s1[0])==len(s1)', 's1=[1]*5000', number=10000)
0.26274609565734863
>>> timeit.timeit('s1.count(s1[0])==len(s1)', 's1=[1]*4999+[2]', number=10000)
0.25654196739196777

Having the .htaccess file on the root folder, add this line. Make sure to delete all other useless rules you tried before:

Options -Indexes

Or try:

Options All -Indexes

You can convert BigDecimal to double using .doubleValue(). But believe me, don't use it if you have currency manipulations. It should always be performed on BigDecimal objects directly. Precision loss in these calculations are big time problems in currency related calculations.

Create a dummy tag that is not going to rendered on the page but it will work as holder for ng-repeat:

<dummyTag ng-repeat="featureItem in item.features">{{featureItem.feature}}</br> </dummyTag>

In case it's useful to anyone, you can download from my web site a small Java agent for querying the memory usage of an object. It'll let you query "deep" memory usage as well.

substringsArray.every(substring=>yourBigString.indexOf(substring) === -1)

For full support ;)

Simple !!... you can do it easily via server.xml

• Go to tomcat>conf folder
• Edit server.xml
• Search "Connector port"
• Replace "8080" by your port number
• Restart tomcat server.

You are done!.

So this is ancient, but there's a much better modern solution. Not sure what version of c#/.NET is required, but this is how I do it:

... Other method code not relevant to the question.

// a token source that will timeout at the specified interval, or if cancelled outside of this scope
using var timeoutTokenSource = new CancellationTokenSource(TimeSpan.FromSeconds(5));
using var linkedTokenSource = CancellationTokenSource.CreateLinkedTokenSource(token, timeoutTokenSource.Token);

async Task<MessageResource> FetchAsync()
{
    try
    {
        return await MessageResource.FetchAsync(m.Sid);
    } catch (TaskCanceledException e)
    {
        if (timeoutTokenSource.IsCancellationRequested)
            throw new TimeoutException("Timeout", e);
        throw;
    }
}

return await Task.Run(FetchAsync, linkedTokenSource.Token);

the CancellationTokenSource constructor takes a TimeSpan parameter which will cause that token to cancel after that interval has elapsed. You can then wrap your async (or syncronous, for that matter) code in another call to Task.Run, passing the timeout token.

This assumes you're passing in a cancellation token (the token variable). If you don't have a need to cancel the task separately from the timeout, you can just use timeoutTokenSource directly. Otherwise, you create linkedTokenSource, which will cancel if the timeout ocurrs, or if it's otherwise cancelled.

We then just catch OperationCancelledException and check which token threw the exception, and throw a TimeoutException if a timeout caused this to raise. Otherwise, we rethrow.

Also, I'm using local functions here, which were introduced in C# 7, but you could easily use lambda or actual functions to the same affect. Similarly, c# 8 introduced a simpler syntax for using statements, but those are easy enough to rewrite.

Check out the manual: http://www.php.net/manual/en/datetime.format.php

<?php
$date = new DateTime('2000-01-01');
echo $date->format('Y-m-d H:i:s');
?>

Will output: 2000-01-01 00:00:00

One solution to this problem could be to provide a variable scope encapsulating the while loop:

{
  // all tmp loop variables here ....
  // ....
  String str;
  while(condition){
      str = calculateStr();
      .....
  }
}

They would be automatically de-reference when the outer scope ends.

Solved the problem with:

sudo chown -R $USER:$USER /var/www/folder-name

sudo chmod -R 755 /var/www

Grant permissions

You should do it with getActivity().startActivity(myIntent)

For BootsTrap Calender use this

/The Calender Index CSS/

.bootstrap-datetimepicker-widget {
   z-index:99999 !important;
}

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

Instead, use: sudo service redis-server start

I had the same problem, stopping/starting other services from within Ubuntu on WSL. This worked, where systemctl did not.

And one could reasonably wonder, "how would you know that the service name was 'redis-server'?" You can see them using service --status-all

If you don't need to initiate a post back when you press this button, then making the overhead of a server control isn't necesary.

<input id="addButton" type="button" value="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#addButton').click(function() 
         { 
             showDialog('#addPerson'); 
         });
     });
</script>

If you still need to be able to do a post back, you can conditionally stop the rest of the button actions with a little different code:

<asp:Button ID="buttonAdd" runat="server" Text="Add" />

<script type="text/javascript" language="javascript">
     $(document).ready(function()
     {
         $('#<%= buttonAdd.ClientID %>').click(function(e) 
         { 
             showDialog('#addPerson');

             if(/*Some Condition Is Not Met*/) 
                return false;
         });
     });
</script>

To put it in very practical terms:

If you use a const in dll A and dll B references that const, the value of that const will be compiled into dll B. If you redeploy dll A with a new value for that const, dll B will still be using the original value.

If you use a readonly in dll A and dll B references that readonly, that readonly will always be looked up at runtime. This means if you redeploy dll A with a new value for that readonly, dll B will use that new value.

The simplest way is to delete <title> tag from index.html, and include

<head>
<title> Website - The page </title></head>

in every page in the web. Spiders will find this and will be shown in search results :)

If by any chance you use VSCode and has installed the docker extension, just right+click on the docker you want to check (within the docker extension), click on Inspect, and there search for env, you will find all your env variables values

or programmaticaly

String s = String.class.getName();
s = s.substring(s.lastIndexOf('.') + 1);

Combine two answers above, I finally make it work. Just be careful that the first single quote for each string is a backtick (`) in file sendmail.mc.

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth  #maybe not, because I cannot apply cmd "cd auth" if I do so.

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

#Add the following lines to sendmail.mc. Make sure you update your smtp server
#The first single quote for each string should be changed to a backtick (`) like this:
define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl

#run 
sudo sendmailconfig

Simple step like this,

<!DOCTYPE html>
<html>
<head>
    <title>Autorefresh Browser using jquery</title>
    <script type="text/javascript" src="jquery.min.js"></script>
    <script type="text/javascript">
        $(function() {
            startRefresh();
        });
        function startRefresh() {
            setTimeout(startRefresh,100);
            $.get('text.html', function(data) {
                $('#viewHere').html(data);
            });
        }
    </script>

</head>

The difference between a tuple and a class is that a tuple has no property names. This is almost never a good thing, and I would only use a tuple when the arguments are fairly meaningless like in an abstract math formula Eg. abstract calculus over 5,6,7 dimensions might take a tuple for the coordinates.

What does void 0 mean?

void^[MDN] is a prefix keyword that takes one argument and always returns undefined.

Examples

void 0
void (0)
void "hello"
void (new Date())
//all will return undefined

What's the point of that?

It seems pretty useless, doesn't it? If it always returns undefined, what's wrong with just using undefined itself?

In a perfect world we would be able to safely just use undefined: it's much simpler and easier to understand than void 0. But in case you've never noticed before, this isn't a perfect world, especially when it comes to Javascript.

The problem with using undefined was that undefined is not a reserved word (it is actually a property of the global object ^[wtfjs]). That is, undefined is a permissible variable name, so you could assign a new value to it at your own caprice.

alert(undefined); //alerts "undefined"
var undefined = "new value";
alert(undefined) // alerts "new value"

Note: This is no longer a problem in any environment that supports ECMAScript 5 or newer (i.e. in practice everywhere but IE 8), which defines the undefined property of the global object as read-only (so it is only possible to shadow the variable in your own local scope). However, this information is still useful for backwards-compatibility purposes.

alert(window.hasOwnProperty('undefined')); // alerts "true"
alert(window.undefined); // alerts "undefined"
alert(undefined === window.undefined); // alerts "true"
var undefined = "new value";
alert(undefined); // alerts "new value"
alert(undefined === window.undefined); // alerts "false"

void, on the other hand, cannot be overidden. void 0 will always return undefined. undefined, on the other hand, can be whatever Mr. Javascript decides he wants it to be.

Why void 0, specifically?

Why should we use void 0? What's so special about 0? Couldn't we just as easily use 1, or 42, or 1000000 or "Hello, world!"?

And the answer is, yes, we could, and it would work just as well. The only benefit of passing in 0 instead of some other argument is that 0 is short and idiomatic.

Why is this still relevant?

Although undefined can generally be trusted in modern JavaScript environments, there is one trivial advantage of void 0: it's shorter. The difference is not enough to worry about when writing code but it can add up enough over large code bases that most code minifiers replace undefined with void 0 to reduce the number of bytes sent to the browser.

Building on the solution provided I thought it might be helpful to show an example passing your own custom data object (which I've referenced here as 'message' as per question).

Class A (sender):

YourDataObject *message = [[YourDataObject alloc] init];
// set your message properties
NSDictionary *dict = [NSDictionary dictionaryWithObject:message forKey:@"message"];
[[NSNotificationCenter defaultCenter] postNotificationName:@"NotificationMessageEvent" object:nil userInfo:dict];

Class B (receiver):

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[NSNotificationCenter defaultCenter]
     addObserver:self selector:@selector(triggerAction:) name:@"NotificationMessageEvent" object:nil];
}

#pragma mark - Notification
-(void) triggerAction:(NSNotification *) notification
{
    NSDictionary *dict = notification.userInfo;
    YourDataObject *message = [dict valueForKey:@"message"];
    if (message != nil) {
        // do stuff here with your message data
    }
}

This kind of thing doesn't just magically happen on its own; you changed something! In industry we use version control to make regular savepoints, so when something goes wrong we can trace back the specific changes we made that resulted in that problem.

Since you haven't done that here, we can only really guess. In Visual Studio, Intellisense (the technology that gives you auto-complete dropdowns and those squiggly red lines) works separately from the actual C++ compiler under the bonnet, and sometimes gets things a bit wrong.

In this case I'd ask why you're including both cstdlib and stdlib.h; you should only use one of them, and I recommend the former. They are basically the same header, a C header, but cstdlib puts them in the namespace std in order to "C++-ise" them. In theory, including both wouldn't conflict but, well, this is Microsoft we're talking about. Their C++ toolchain sometimes leaves something to be desired. Any time the Intellisense disagrees with the compiler has to be considered a bug, whichever way you look at it!

Anyway, your use of using namespace std (which I would recommend against, in future) means that std::system from cstdlib now conflicts with system from stdlib.h. I can't explain what's going on with std::cout and std::cin.

Try removing #include <stdlib.h> and see what happens.

If your program is building successfully then you don't need to worry too much about this, but I can imagine the false positives being annoying when you're working in your IDE.

There is a comparison of the features and performance of RabbitMQ ActiveMQ and QPID given at
http://bhavin.directi.com/rabbitmq-vs-apache-activemq-vs-apache-qpid/

Personally I have tried all the above three. RabbitMQ is the best performance wise according to me, but it does not have failover and recovery options. ActiveMQ has the most features, but is slower.

Update : HornetQ is also an option you can look into, it is JMS Complaint, a better option than ActiveMQ if you are looking for a JMS based solution.

As the other answers didn't address my concern I decided to write my own answer.

The path given in the icon attribute of the md-icon directive is the URL of a .png or .svg file lying somewhere in your static file directory. So you have to put the right path of that file in the icon attribute. p.s put the file in the right directory so that your server could serve it.

Remember md-icon is not like bootstrap icons. Currently they are merely a directive that shows a .svg file.

Update

Angular material design has changed a lot since this question was posted.

Now there are several ways to use md-icon

The first way is to use SVG icons.

<md-icon md-svg-src = '<url_of_an_image_file>'></md-icon>

Example:

<md-icon md-svg-src = '/static/img/android.svg'></md-icon>

or

<md-icon md-svg-src = '{{ getMyIcon() }}'></md-icon>

:where getMyIcon is a method defined in $scope.

or <md-icon md-svg-icon="social:android"></md-icon>

to use this you have to the $mdIconProvider service to configure your application with svg iconsets.

angular.module('appSvgIconSets', ['ngMaterial'])  
  .controller('DemoCtrl', function($scope) {})  
  .config(function($mdIconProvider) {
    $mdIconProvider
      .iconSet('social', 'img/icons/sets/social-icons.svg', 24)
      .defaultIconSet('img/icons/sets/core-icons.svg', 24);    
  });

The second way is to use font icons.

<md-icon md-font-icon="android" alt="android"></md-icon>

<md-icon md-font-icon="fa-magic" class="fa" alt="magic wand"></md-icon>

prior to doing this you have to load the font library like this..

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

or use font icons with ligatures

<md-icon md-font-library="material-icons">face</md-icon>

<md-icon md-font-library="material-icons">#xE87C;</md-icon>

<md-icon md-font-library="material-icons" class="md-light md-48">face</md-icon>

For further details check our

Angular Material mdIcon Directive documentation

Given a dataset

df <- data.frame( sex = c('M', 'M', 'F', 'F', 'M'), 
                  occupation = c('analyst', 'dentist', 'dentist', 'analyst', 'cook') )

you can subset rows

df[df$sex == 'M',] # To get all males
df[df$occupation == 'analyst',] # All analysts

etc.

If you want to get number of rows, just call the function nrow such as

nrow(df[df$sex == 'M',])

Hi Guys I Did Something like this. For N-th Depth Copy Folder and Files to copy. Which Allows you to copy all the directory structure to copy from Android AssetManager :)

    private void manageAssetFolderToSDcard()
    {

        try
        {
            String arg_assetDir = getApplicationContext().getPackageName();
            String arg_destinationDir = FRConstants.ANDROID_DATA + arg_assetDir;
            File FolderInCache = new File(arg_destinationDir);
            if (!FolderInCache.exists())
            {
                copyDirorfileFromAssetManager(arg_assetDir, arg_destinationDir);
            }
        } catch (IOException e1)
        {

            e1.printStackTrace();
        }

    }


    public String copyDirorfileFromAssetManager(String arg_assetDir, String arg_destinationDir) throws IOException
    {
        File sd_path = Environment.getExternalStorageDirectory(); 
        String dest_dir_path = sd_path + addLeadingSlash(arg_destinationDir);
        File dest_dir = new File(dest_dir_path);

        createDir(dest_dir);

        AssetManager asset_manager = getApplicationContext().getAssets();
        String[] files = asset_manager.list(arg_assetDir);

        for (int i = 0; i < files.length; i++)
        {

            String abs_asset_file_path = addTrailingSlash(arg_assetDir) + files[i];
            String sub_files[] = asset_manager.list(abs_asset_file_path);

            if (sub_files.length == 0)
            {
                // It is a file
                String dest_file_path = addTrailingSlash(dest_dir_path) + files[i];
                copyAssetFile(abs_asset_file_path, dest_file_path);
            } else
            {
                // It is a sub directory
                copyDirorfileFromAssetManager(abs_asset_file_path, addTrailingSlash(arg_destinationDir) + files[i]);
            }
        }

        return dest_dir_path;
    }


    public void copyAssetFile(String assetFilePath, String destinationFilePath) throws IOException
    {
        InputStream in = getApplicationContext().getAssets().open(assetFilePath);
        OutputStream out = new FileOutputStream(destinationFilePath);

        byte[] buf = new byte[1024];
        int len;
        while ((len = in.read(buf)) > 0)
            out.write(buf, 0, len);
        in.close();
        out.close();
    }

    public String addTrailingSlash(String path)
    {
        if (path.charAt(path.length() - 1) != '/')
        {
            path += "/";
        }
        return path;
    }

    public String addLeadingSlash(String path)
    {
        if (path.charAt(0) != '/')
        {
            path = "/" + path;
        }
        return path;
    }

    public void createDir(File dir) throws IOException
    {
        if (dir.exists())
        {
            if (!dir.isDirectory())
            {
                throw new IOException("Can't create directory, a file is in the way");
            }
        } else
        {
            dir.mkdirs();
            if (!dir.isDirectory())
            {
                throw new IOException("Unable to create directory");
            }
        }
    }

In the end Create a Asynctask:

    private class ManageAssetFolders extends AsyncTask<Void, Void, Void>
    {

        @Override
        protected Void doInBackground(Void... arg0)
        {
            manageAssetFolderToSDcard();
            return null;
        }

    }

call it From your activity:

    new ManageAssetFolders().execute();

I run into this problem a lot with virtual machines.

For me the following works:

cd /path/to/your/project
rm -rf .git

If you want to save yourself some downloads - go in your file explorer and delete all files in the folder that are already committed and leave in your /vendor and /node_modules (I work with composer and npm) folders.

then just create a new repo

git init

add your remote

git remote add origin ssh://[email protected]/YourUsername/repoName.git

and fetch the branch / all of it

git fetch origin somebranch

and check it out

git checkout somebranch

then you should be at the point before the error.

Hope this helps.

Regards.

Use a HashSet<T>. For example:

var items = "A B A D A C".Split(' ');
var unique_items = new HashSet<string>(items);
foreach (string s in unique_items)
    Console.WriteLine(s);

prints

A
B
D
C

Hmm, from the examples you gave it seems like "$_SERVER['REQUEST_URI']" and the explode() function could help you. You could use explode to break up the URL following the domain name into an array, separating it at each forward-slash.

As a very basic example, something like this could be implemented:

$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
foreach($crumbs as $crumb){
    echo ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
}

I ran into a similar problem while creating a library to handle authentication. I want the app owner using my library to be able to register a callback with the library for checking authorization against LDAP groups the authenticated person is in. The configuration is getting passed in as a config.py file that gets imported and contains a dict with all the config parameters.

I got this to work:

>>> class MyClass(object):
...     def target_func(self):
...         print "made it!"
...    
...     def __init__(self,config):
...         self.config = config
...         self.config['funcname'] = getattr(self,self.config['funcname'])
...         self.config['funcname']()
... 
>>> instance = MyClass({'funcname':'target_func'})
made it!

Is there a pythonic-er way to do this?

Heres a variant on WWs answer, it includes partitions and sub-partitions as others above have suggested, plus a column to show the TYPE: Table/Index/LOB etc

SELECT
   owner, "Type", table_name "Name", TRUNC(sum(bytes)/1024/1024) Meg
FROM
(  SELECT segment_name table_name, owner, bytes, 'Table' as "Type"
   FROM dba_segments
   WHERE segment_type in  ('TABLE','TABLE PARTITION','TABLE SUBPARTITION')
 UNION ALL
   SELECT i.table_name, i.owner, s.bytes, 'Index' as "Type"
   FROM dba_indexes i, dba_segments s
   WHERE s.segment_name = i.index_name
   AND   s.owner = i.owner
   AND   s.segment_type in ('INDEX','INDEX PARTITION','INDEX SUBPARTITION')
 UNION ALL
   SELECT l.table_name, l.owner, s.bytes, 'LOB' as "Type"
   FROM dba_lobs l, dba_segments s
   WHERE s.segment_name = l.segment_name
   AND   s.owner = l.owner
   AND   s.segment_type IN ('LOBSEGMENT','LOB PARTITION','LOB SUBPARTITION')
 UNION ALL
   SELECT l.table_name, l.owner, s.bytes, 'LOB Index' as "Type"
   FROM dba_lobs l, dba_segments s
   WHERE s.segment_name = l.index_name
   AND   s.owner = l.owner
   AND   s.segment_type = 'LOBINDEX')
   WHERE owner in UPPER('&owner')
GROUP BY table_name, owner, "Type"
HAVING SUM(bytes)/1024/1024 > 10  /* Ignore really small tables */
ORDER BY SUM(bytes) desc;

full path for binary file. For example: /home/vitaliy2034/binary_file_name. Or use directive "./+binary_file_name". './' in unix system it return full path to directory, in which you open terminal(shell). I hope it helps. Sorry, for my english language)

ls -ltrh /proc | grep YOUR-PID-HERE

For example, my Google Chrome's PID is 11583:

ls -l /proc | grep 11583
dr-xr-xr-x  7 adam       adam                     0 2011-04-20 16:34 11583

Use json_decode to convert String into Object (stdClass) or array: http://php.net/manual/en/function.json-decode.php

[edited]

I did not understand what do you mean by "an official JSON object", but suppose you want to add content to json via PHP and then converts it right back to JSON?

assuming you have the following variable:

$data = '{"Coords":[{"Accuracy":"65","Latitude":"53.277720488429026","Longitude":"-9.012038778269686","Timestamp":"Fri Jul 05 2013 11:59:34 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.277720488429026","Longitude":"-9.012038778269686","Timestamp":"Fri Jul 05 2013 11:59:34 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27770755361785","Longitude":"-9.011979642121824","Timestamp":"Fri Jul 05 2013 12:02:09 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27769091555766","Longitude":"-9.012051410095722","Timestamp":"Fri Jul 05 2013 12:02:17 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27769091555766","Longitude":"-9.012051410095722","Timestamp":"Fri Jul 05 2013 12:02:17 GMT+0100 (IST)"}]}';

You should convert it to Object (stdClass):

$manage = json_decode($data);

But working with stdClass is more complicated than PHP-Array, then try this (use second param with true):

$manage = json_decode($data, true);

This way you can use array functions: http://php.net/manual/en/function.array.php

adding an item:

$manage = json_decode($data, true);

echo 'Before: <br>';
print_r($manage);

$manage['Coords'][] = Array(
    'Accuracy' => '90'
    'Latitude' => '53.277720488429026'
    'Longitude' => '-9.012038778269686'
    'Timestamp' => 'Fri Jul 05 2013 11:59:34 GMT+0100 (IST)'
);

echo '<br>After: <br>';
print_r($manage);

remove first item:

$manage = json_decode($data, true);
echo 'Before: <br>';
print_r($manage);
array_shift($manage['Coords']);
echo '<br>After: <br>';
print_r($manage);

any chance you want to save to json to a database or a file:

$data = '{"Coords":[{"Accuracy":"65","Latitude":"53.277720488429026","Longitude":"-9.012038778269686","Timestamp":"Fri Jul 05 2013 11:59:34 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.277720488429026","Longitude":"-9.012038778269686","Timestamp":"Fri Jul 05 2013 11:59:34 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27770755361785","Longitude":"-9.011979642121824","Timestamp":"Fri Jul 05 2013 12:02:09 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27769091555766","Longitude":"-9.012051410095722","Timestamp":"Fri Jul 05 2013 12:02:17 GMT+0100 (IST)"},{"Accuracy":"65","Latitude":"53.27769091555766","Longitude":"-9.012051410095722","Timestamp":"Fri Jul 05 2013 12:02:17 GMT+0100 (IST)"}]}';

$manage = json_decode($data, true);

$manage['Coords'][] = Array(
    'Accuracy' => '90'
    'Latitude' => '53.277720488429026'
    'Longitude' => '-9.012038778269686'
    'Timestamp' => 'Fri Jul 05 2013 11:59:34 GMT+0100 (IST)'
);

if (($id = fopen('datafile.txt', 'wb'))) {
    fwrite($id, json_encode($manage));
    fclose($id);
}

I hope I have understood your question.

Good luck.

Just a little addition: I believe it's a common and known thing to add exit; after the header function in case we don't want the rest of the code to load or execute...

header('Location: ' . $_SERVER['HTTP_REFERER']);
exit;

What worked for me was this lazy approach, not algorithmically lazy ;)

if( JSON.stringify(object_name).indexOf("key_name") > -1 ) {
    console.log("Key Found");
}
else{
    console.log("Key not Found");
}

Try YouCompleteMe. It uses Clang through the libclang interface, offering semantic C/C++/Objective-C completion. It's much like clang_complete, but substantially faster and with fuzzy-matching.

In addition to the above, YCM also provides semantic completion for C#, Python, Go, TypeScript etc. It also provides non-semantic, identifier-based completion for languages for which it doesn't have semantic support.

Value 127 is returned by /bin/sh when the given command is not found within your PATH system variable and it is not a built-in shell command. In other words, the system doesn't understand your command, because it doesn't know where to find the binary you're trying to call.

You can also try this

string.Join(null,System.Text.RegularExpressions.Regex.Split(expr, "[^\\d]"));

use for each loop for accessing keys in Object or Maps in javascript

for(key in foo){
   console.log(key);//for key name in your case it will be bar
   console.log(foo[key]);// for key value in your case it will be baz
}

Note: you can also use

Object.keys(foo);

it will give you like this output:

[bar];

1. you need to convert SVG to XML to use in android project.

1.1 you can do this with this site: http://inloop.github.io/svg2android/ but it does not support all the features of SVG like some gradients.

1.2 you can convert via android studio but it might use some features that only supports API 24 and higher that cuase crashe your app in older devices.

and add vectorDrawables.useSupportLibrary = true in gradle file and use like this:

<android.support.v7.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:srcCompat="@drawable/ic_item1" />

2. use this library https://github.com/MegatronKing/SVG-Android that supports these features : https://github.com/MegatronKing/SVG-Android/blob/master/support_doc.md

add this code in application class:

public void onCreate() {
    SVGLoader.load(this)
}

and use the SVG like this :

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_android_red"/>

sometimes your device stops trusting your PC for no reseaon. go to your settings then general > reset > reset location and privacy. and replug your device to your PC again and press "trust this device" prompt that shows up in your phone.

If you want to upload file using AJAX here is code which you can use for file uploading.

$(document).ready(function() {
    var options = { 
                beforeSubmit:  showRequest,
        success:       showResponse,
        dataType: 'json' 
        }; 
    $('body').delegate('#image','change', function(){
        $('#upload').ajaxForm(options).submit();        
    }); 
});     
function showRequest(formData, jqForm, options) { 
    $("#validation-errors").hide().empty();
    $("#output").css('display','none');
    return true; 
} 
function showResponse(response, statusText, xhr, $form)  { 
    if(response.success == false)
    {
        var arr = response.errors;
        $.each(arr, function(index, value)
        {
            if (value.length != 0)
            {
                $("#validation-errors").append('<div class="alert alert-error"><strong>'+ value +'</strong><div>');
            }
        });
        $("#validation-errors").show();
    } else {
         $("#output").html("<img src='"+response.file+"' />");
         $("#output").css('display','block');
    }
}

Here is the HTML for Upload the file

<form class="form-horizontal" id="upload" enctype="multipart/form-data" method="post" action="upload/image'" autocomplete="off">
    <input type="file" name="image" id="image" /> 
</form>

You could use a literal eval:

>>> ast.literal_eval('0xdeadbeef')
3735928559

Or just specify the base as argument to int:

>>> int('deadbeef', 16)
3735928559

A trick that is not well known, if you specify the base 0 to int, then Python will attempt to determine the base from the string prefix:

>>> int("0xff", 0)
255
>>> int("0o644", 0)
420
>>> int("0b100", 0)
4
>>> int("100", 0)
100

I assume you are using the caption feature of Word, that is, captions were not typed in as normal text, but were inserted using Insert > Caption (Word versions before 2007), or References > Insert Caption (in the ribbon of Word 2007 and up). If done correctly, the captions are really 'fields'. You'll know if it is a field if the caption's background turns grey when you put your cursor on them (or is permanently displayed grey).

Captions are fields - Unfortunately fields (like caption fields) are only updated on specific actions, like opening of the document, printing, switching from print view to normal view, etc. The easiest way to force updating of all (caption) fields when you want it is by doing the following:

1. Select all text in your document (easiest way is to press ctrl-a)
2. Press F9, this command tells Word to update all fields in the selection.

Captions are normal text - If the caption number is not a field, I am afraid you'll have to edit the text manually.

simply create two list in adapter one orignal and one temp and implements Filterable.

    @Override
    public Filter getFilter() {
        return new Filter() {
            @Override
            protected FilterResults performFiltering(CharSequence constraint) {
                final FilterResults oReturn = new FilterResults();
                final ArrayList<T> results = new ArrayList<>();
                if (origList == null)
                    origList = new ArrayList<>(itemList);
                if (constraint != null && constraint.length() > 0) {
                    if (origList != null && origList.size() > 0) {
                        for (final T cd : origList) {
                            if (cd.getAttributeToSearch().toLowerCase()
                                    .contains(constraint.toString().toLowerCase()))
                                results.add(cd);
                        }
                    }
                    oReturn.values = results;
                    oReturn.count = results.size();//newly Aded by ZA
                } else {
                    oReturn.values = origList;
                    oReturn.count = origList.size();//newly added by ZA
                }
                return oReturn;
            }

            @SuppressWarnings("unchecked")
            @Override
            protected void publishResults(final CharSequence constraint,
                                          FilterResults results) {
                itemList = new ArrayList<>((ArrayList<T>) results.values);
                // FIXME: 8/16/2017 implement Comparable with sort below
                ///Collections.sort(itemList);
                notifyDataSetChanged();
            }
        };
    }

where

public GenericBaseAdapter(Context mContext, List<T> itemList) {
        this.mContext = mContext;
        this.itemList = itemList;
        this.origList = itemList;
    }

It is also possible to migrate data using the SLAVEOF command:

SLAVEOF old_instance_name old_instance_port

Check that you have receive the keys with KEYS *. You could test the new instance by any other way too, and when you are done just turn replication of:

SLAVEOF NO ONE

Specifying pointer-events: none in CSS disables mouse input but doesn't disable keyboard input. For example, the user can still tab to the link and "click" it by pressing the Enter key or (in Windows) the ? Menu key. You could disable specific keystrokes by intercepting the keydown event, but this would likely confuse users relying on assistive technologies.

Probably the best way to disable a link is to remove its href attribute, making it a non-link. You can do this dynamically with a conditional href attribute binding:

<a *ngFor="let link of links"
   [attr.href]="isDisabled(link) ? null : '#'"
   [class.disabled]="isDisabled(link)"
   (click)="!isDisabled(link) && onClick(link)">
   {{ link.name }}
</a>

Or, as in Günter Zöchbauer's answer, you can create two links, one normal and one disabled, and use *ngIf to show one or the other:

<ng-template ngFor #link [ngForOf]="links">
    <a *ngIf="!isDisabled(link)" href="#" (click)="onClick(link)">{{ link.name }}</a>
    <a *ngIf="isDisabled(link)" class="disabled">{{ link.name }}</a>
</ng-template>

Here's some CSS to make the link look disabled:

a.disabled {
    color: gray;
    cursor: not-allowed;
    text-decoration: underline;
}

The Google Testing Blog discussed this problem recently:

So a naive answer is that writing test carries a 10% tax. But, we pay taxes in order to get something in return.

(snip)

These benefits translate to real value today as well as tomorrow. I write tests, because the additional benefits I get more than offset the additional cost of 10%. Even if I don't include the long term benefits, the value I get from test today are well worth it. I am faster in developing code with test. How much, well that depends on the complexity of the code. The more complex the thing you are trying to build is (more ifs/loops/dependencies) the greater the benefit of tests are.

run github that you downloaded, click tools and options symbol(top right), click about github for windows and then open the debug log. under DIAGNOSTICS look for Git Executable Exists:

Bundling is all about compressing several JavaScript or stylesheets files without any formatting (also referred as minified) into a single file for saving bandwith and number of requests to load a page.

As example you could create your own bundle:

bundles.Add(New ScriptBundle("~/bundles/mybundle").Include(
            "~/Resources/Core/Javascripts/jquery-1.7.1.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-1.8.16.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.min.js",
            "~/Resources/Core/Javascripts/jquery.validate.unobtrusive.min.js",
            "~/Resources/Core/Javascripts/jquery.unobtrusive-ajax.min.js",
            "~/Resources/Core/Javascripts/jquery-ui-timepicker-addon.js"))

And render it like this:

@Scripts.Render("~/bundles/mybundle")

One more advantage of @Scripts.Render("~/bundles/mybundle") over the native <script src="~/bundles/mybundle" /> is that @Scripts.Render() will respect the web.config debug setting:

  <system.web>
    <compilation debug="true|false" />

If debug="true" then it will instead render individual script tags for each source script, without any minification.

For stylesheets you will have to use a StyleBundle and @Styles.Render().

Instead of loading each script or style with a single request (with script or link tags), all files are compressed into a single JavaScript or stylesheet file and loaded together.

found one interesting cheat sheet here.. http://introcs.cs.princeton.edu/java/11cheatsheet/

This if clause easily checks if location services are available in my opinion:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if(!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER) && !locationManager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)) {
        //All location services are disabled

}

Its late, yet it's worth your time nothing that, there are some differences in browser level implementation of focusin and focusout events and react synthetic onFocus and onBlur. focusin and focusout actually bubble, while onFocus and onBlur dont. So there is no exact same implementation for focusin and focusout as of now for react. Anyway most cases will be covered in onFocus and onBlur.

Kotlin Code with runOnUiThread

runOnUiThread(
        object : Runnable {
            override fun run() {
                Toast.makeText(applicationContext, "Calling from runOnUiThread()", Toast.LENGTH_SHORT)  
            }
        }
)

Another relevant environment variable is:

%ProgramW6432%

So, on a 64-bit machine running in 32-bit (WOW64) mode:

• echo %programfiles% ==> C:\Program Files (x86)
• echo %programfiles(x86)% ==> C:\Program Files (x86)
• echo %ProgramW6432% ==> C:\Program Files

From Wikipedia:

The %ProgramFiles% variable points to the Program Files directory, which stores all the installed programs of Windows and others. The default on English-language systems is "C:\Program Files". In 64-bit editions of Windows (XP, 2003, Vista), there are also %ProgramFiles(x86)%, which defaults to "C:\Program Files (x86)", and %ProgramW6432%, which defaults to "C:\Program Files". The %ProgramFiles% itself depends on whether the process requesting the environment variable is itself 32-bit or 64-bit (this is caused by Windows-on-Windows 64-bit redirection).

How to resolve this problem in Angular8

polyfills.ts uncomment import 'classlist.js'; and import 'web-animations-js'; then install two dependency using npm install --save classlist.js and npm install --save web-animations-js.

update tsconfig.json with "target":"es5",

then ng serve run the application and open in IE, it will work

If you have multiple Menus with Submenus, then you can go with the below solution.

HTML

          <ul class="sidebar-menu" id="nav-accordion">
             <li class="sub-menu">
                  <a href="" ng-click="hasSubMenu('dashboard')">
                      <i class="fa fa-book"></i>
                      <span>Dashboard</span>
                      <i class="fa fa-angle-right pull-right"></i>
                  </a>
                  <ul class="sub" ng-show="showDash">
                      <li><a ng-class="{ active: isActive('/dashboard/loan')}" href="#/dashboard/loan">Loan</a></li>
                      <li><a ng-class="{ active: isActive('/dashboard/recovery')}" href="#/dashboard/recovery">Recovery</a></li>
                  </ul>
              </li>
              <li class="sub-menu">
                  <a href="" ng-click="hasSubMenu('customerCare')">
                      <i class="fa fa-book"></i>
                      <span>Customer Care</span>
                      <i class="fa fa-angle-right pull-right"></i>
                  </a>
                  <ul class="sub" ng-show="showCC">
                      <li><a ng-class="{ active: isActive('/customerCare/eligibility')}" href="#/CC/eligibility">Eligibility</a></li>
                      <li><a ng-class="{ active: isActive('/customerCare/transaction')}" href="#/CC/transaction">Transaction</a></li>
                  </ul>
              </li>
          </ul>

There are two functions i have called first is ng-click = hasSubMenu('dashboard'). This function will be used to toggle the menu and it is explained in the code below. The ng-class="{ active: isActive('/customerCare/transaction')} it will add a class active to the current menu item.

Now i have defined some functions in my app:

First, add a dependency $rootScope which is used to declare variables and functions. To learn more about $roootScope refer to the link : https://docs.angularjs.org/api/ng/service/$rootScope

Here is my app file:

 $rootScope.isActive = function (viewLocation) { 
                return viewLocation === $location.path();
        };

The above function is used to add active class to the current menu item.

        $rootScope.showDash = false;
        $rootScope.showCC = false;

        var location = $location.url().split('/');

        if(location[1] == 'customerCare'){
            $rootScope.showCC = true;
        }
        else if(location[1]=='dashboard'){
            $rootScope.showDash = true;
        }

        $rootScope.hasSubMenu = function(menuType){
            if(menuType=='dashboard'){
                $rootScope.showCC = false;
                $rootScope.showDash = $rootScope.showDash === false ? true: false;
            }
            else if(menuType=='customerCare'){
                $rootScope.showDash = false;
                $rootScope.showCC = $rootScope.showCC === false ? true: false;
            }
        }

By default $rootScope.showDash and $rootScope.showCC are set to false. It will set the menus to closed when page is initially loaded. If you have more than two submenus add accordingly.

hasSubMenu() function will work for toggling between the menus. I have added a small condition

if(location[1] == 'customerCare'){
                $rootScope.showCC = true;
            }
            else if(location[1]=='dashboard'){
                $rootScope.showDash = true;
            }

it will remain the submenu open after reloading the page according to selected menu item.

I have defined my pages like:

$routeProvider
        .when('/dasboard/loan', {
            controller: 'LoanController',
            templateUrl: './views/loan/view.html',
            controllerAs: 'vm'
        })

You can use isActive() function only if you have a single menu without submenu. You can modify the code according to your requirement. Hope this will help. Have a great day :)

Check out this plunkr.

When you're binding to variables, you need to use the brackets. Also, you use the hashtag when you want to get references to elements in your html, not for declaring variables inside of templates like that.

<md-button-toggle *ngFor="let indicador of indicadores; let first = first;" [value]="indicador.id" [checked]="first"> 
...

Edit: Thanks to Christopher Moore: Angular exposes the following local variables:

• index
• first
• last
• even
• odd

Pure javascript version, which works in all browsers:

document.onkeydown = function(e) {stopDefaultBackspaceBehaviour(e);}
document.onkeypress = function(e) {stopDefaultBackspaceBehaviour(e);}

function stopDefaultBackspaceBehaviour(event) {
  var event = event || window.event;
  if (event.keyCode == 8) {
    var elements = "HTML, BODY, TABLE, TBODY, TR, TD, DIV";
    var d = event.srcElement || event.target;
    var regex = new RegExp(d.tagName.toUpperCase());
    if (regex.test(elements)) {
      event.preventDefault ? event.preventDefault() : event.returnValue = false;
    }
  }
}

Of course you can use "INPUT, TEXTAREA" and use "if (!regex.test(elements))" then. The first worked fine for me.

Yeah, by using $(this), you enabled jQuery functionality for the object. By just using this, it only has generic Javascript functionality.

Other answers would have you disallow a particular number, or tell the user to enter something non-numeric in order to terminate input. Perhaps a better solution is to use std::getline() to read a line of input, then use std::istringstream to read all of the numbers from that line into the vector.

#include <iostream>
#include <sstream>
#include <vector>

int main(int argc, char** argv) {

    std::string line;
    int number;
    std::vector<int> numbers;

    std::cout << "Enter numbers separated by spaces: ";
    std::getline(std::cin, line);
    std::istringstream stream(line);
    while (stream >> number)
        numbers.push_back(number);

    write_vector(numbers);

}

Also, your write_vector() implementation can be replaced with a more idiomatic call to the std::copy() algorithm to copy the elements to an std::ostream_iterator to std::cout:

#include <algorithm>
#include <iterator>

template<class T>
void write_vector(const std::vector<T>& vector) {
    std::cout << "Numbers you entered: ";
    std::copy(vector.begin(), vector.end(),
        std::ostream_iterator<T>(std::cout, " "));
    std::cout << '\n';
}

You can also use std::copy() and a couple of handy iterators to get the values into the vector without an explicit loop:

std::copy(std::istream_iterator<int>(stream),
    std::istream_iterator<int>(),
    std::back_inserter(numbers));

But that’s probably overkill.

Is it that success() returns earlier than complete()?

Yes; the AJAX success() method runs before the complete() method.

Below is a diagram illustrating the process flow:

It is important to note that

• The success() (Local Event) is only called if the request was successful (no errors from the server, no errors with the data).

• On the other hand, the complete() (Local Event) is called regardless of if the request was successful, or not. You will always receive a complete callback, even for synchronous requests.

... more details on AJAX Events here.

Here is what I figured, and this happened recently on Windows 10 after an update was installed. From what I gathered, a Windows Defender update was installed which assumed my "Project.dll"(an asp.net core project) behaved like a virus so it was deleted.

So, one of the first things I suggest you do before you start installing/uninstalling stuffs is to check to confirm your "Project.dll" is where it should be.

Copy it back to the location if it is no longer there.

If you are having difficulty copying the file back add an exclusion to your project folder in windows defender. ( Learn how to do that here. )

This worked for me instantly, and I repeated it across application multiple servers.

In case anyone else runs into this. I have a web site that was working fine on the desktop browser but I was getting 400 errors with Android devices.

It turned out to be the anti forgery token.

$.ajax({
        url: "/Cart/AddProduct/",
        data: {
            __RequestVerificationToken: $("[name='__RequestVerificationToken']").val(),
            productId: $(this).data("productcode")
        },

The problem was that the .Net controller wasn't set up correctly.

I needed to add the attributes to the controller:

    [AllowAnonymous]
    [IgnoreAntiforgeryToken]
    [DisableCors]
    [HttpPost]
    public async Task<JsonResult> AddProduct(int productId)
    {

The code needs review but for now at least I know what was causing it. 400 error not helpful at all.

One simple way is

Comparator<Dog> ageAscendingComp = ...;
Comparator<Dog> ageDescendingComp = Collections.reverseOrder(ageAscendingComp);
// then call the sort method

On a side note, Dog should really not implement Comparator. It means you have to do strange things like

Collections.sort(myList, new Dog("Rex", 4));
// ^-- why is a new dog being made? What are we even sorting by?!
Collections.sort(myList, myList.get(0));
// ^-- or perhaps more confusingly

Rather you should make Compartors as separate classes.

eg.

public class DogAgeComparator implments Comparator<Dog> {
    public int compareTo(Dog d1, Dog d2) {
        return d1.getAge() - d2.getAge();
    }
}

This has the added benefit that you can use the name of the class to say how the Comparator will sort the list. eg.

Collections.sort(someDogs, new DogNameComparator());
// now in name ascending order

Collections.sort(someDogs, Collections.reverseOrder(new DogAgeComparator()));
// now in age descending order

You should also not not have Dog implement Comparable. The Comparable interface is used to denote that there is some inherent and natural way to order these objects (such as for numbers and strings). Now this is not the case for Dog objects as sometimes you may wish to sort by age and sometimes you may wish to sort by name.

Here is some code that show how it works.

class Test
{
    public static void main(String args[]) 
    { 
        System.out.println(Test.test()); 
    }

    public static String test()
    {
        try {
            System.out.println("try");
            throw new Exception();
        } catch(Exception e) {
            System.out.println("catch");
            return "return"; 
        } finally {  
            System.out.println("finally");
            return "return in finally"; 
        }
    }
}

The results is:

try
catch
finally
return in finally

In a controller action, you could just do:

public function someAction(Request $request)
{
    $routeName = $request->route()->getName();
}

$request here is resolved by Laravel's service container.

getName() returns the route name for named routes only, null otherwise (but you could still explore the \Illuminate\Routing\Route object for something else of interest).

In other words, you should have your route defined like this to have "nameOfMyRoute" returned:

Route::get('my/some-action', [
    'as' => 'nameOfMyRoute',
    'uses' => 'MyController@someAction'
]);

According to the Apple Human Interface Guidelines:

@1x : about 25 x 25 (max: 48 x 32)

@2x : about 50 x 50 (max: 96 x 64)

@3x : about 75 x 75 (max: 144 x 96)

Almost all Oracle deployments are done through SQL*Plus (that weird little command line tool that your DBA uses). And in SQL*Plus a lone slash basically means "re-execute last SQL or PL/SQL command that I just executed".

See

http://ss64.com/ora/syntax-sqlplus.html

Rule of thumb would be to use slash with things that do BEGIN .. END or where you can use CREATE OR REPLACE.

For inserts that need to be unique use

INSERT INTO my_table ()
SELECT <values to be inserted>
FROM dual
WHERE NOT EXISTS (SELECT 
                  FROM my_table
                  WHERE <identify data that you are trying to insert>)

Yes.! We can but with some media queries & Maximum no of columns are predefined.

NOTE
1) No need to create child div. It may be any other tag like 'img' r whatever you want..
2) If you want more columns adjust the media queries and maximum no.of columns.

this work for me in a spring application making one http request every 2 minute to the root url path `

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.web.client.RestTemplate;

public class HerokuNotIdle {

private static final Logger LOG = LoggerFactory.getLogger(HerokuNotIdle.class);

@Scheduled(fixedDelay=120000)
public void herokuNotIdle(){
    LOG.debug("Heroku not idle execution");
    RestTemplate restTemplate = new RestTemplate();
    restTemplate.getForObject("http://yourapp.herokuapp.com/", Object.class);
}
}

Remember config your context to enable scheduler and create the bean for your scheduler

@EnableScheduling
public class AppConfig {

@Bean
public HerokuNotIdle herokuNotIdle(){
    return new HerokuNotIdle();
}
}

Short and simply with printf and json_encode:

function console_log($data) {
    printf('<script>console.log(%s);</script>', json_encode($data));
}

The bitmap constructor has resizing built in.

Bitmap original = (Bitmap)Image.FromFile("DSC_0002.jpg");
Bitmap resized = new Bitmap(original,new Size(original.Width/4,original.Height/4));
resized.Save("DSC_0002_thumb.jpg");

If you want control over interpolation modes see this post.

You are replacing the starting tag and then putting that back in innerHTML, so the code will be invalid. Make all the replacements before you put the code back in the element:

var html = strMessage1.innerHTML;
html = html.replace( /aaaaaa./g,'<a href=\"http://www.google.com/');
html = html.replace( /.bbbbbb/g,'/world\">Helloworld</a>');
strMessage1.innerHTML = html;

OK, I found this post: http://msdn.microsoft.com/en-us/library/aa479319.aspx

with this very illustrative diagram:

_{(source: microsoft.com)}

in essence, to get at those exception details i need to store them myself in Global.asax, for later retrieval on my custom error page.

it seems the best way is to do the bulk of the work in Global.asax, with the custom error pages handling helpful content rather than logic.

$(function() {
  $('.button').click(function() {
    $(this).toggleClass('active');
    $('.yourclass').toggle("slide", {direction: "right"}, 1000);
  });
});

HTML code:

<ul class="list">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
</ul>

CSS code:

ul.list li{
  width: auto;
  float: left;
}

I got this error for a stupid mistake, the variable name in the @PathVariable wasn't matching the one in the @RequestMapping

For example

@RequestMapping(value = "/whatever/{**contentId**}", method = RequestMethod.POST)
public … method(@PathVariable Integer **contentID**){
}

It may help others

yes you can use MapView in v2... for further details you can get help from this

My use of npm is to generate minified/uglified css/js and to generate the javascript needed in pages served by a django application. In my applications, Javascript runs on the page to create animations, some times perform ajax calls, work within a VUE framework and/or work with the css. If package-lock.json has some overriding control over what is in package.json, then it may be necessary that there is one version of this file. In my experience it either does not effect what is installed by npm install, or if it does, It has not to date adversely affected the applications I deploy to my knowledge. I don't use mongodb or other such applications that are traditionally thin client.

I remove package-lock.json from repo because npm install generates this file, and npm install is part of the deploy process on each server that runs the app. Version control of node and npm are done manually on each server, but I am careful that they are the same.

When npm install is run on the server, it changes package-lock.json, and if there are changes to a file that is recorded by the repo on the server, the next deploy WONT allow you to pull new changes from origin. That is you can't deploy because the pull will overwrite the changes that have been made to package-lock.json.

You can't even overwrite a locally generated package-lock.json with what is on the repo (reset hard origin master), as npm will complain when ever you issue a command if the package-lock.json does not reflect what is in node_modules due to npm install, thus breaking the deploy. Now if this indicates that slightly different versions have been installed in node_modules, once again that has never caused me problems.

If node_modules is not on your repo (and it should not be), then package-lock.json should be ignored.

If I am missing something, please correct me in the comments, but the point that versioning is taken from this file makes no sense. The file package.json has version numbers in it, and I assume this file is the one used to build packages when npm install occurs, as when I remove it, npm install complains as follows:

jason@localhost:introcart_wagtail$ rm package.json
jason@localhost:introcart_wagtail$ npm install
npm WARN saveError ENOENT: no such file or directory, open '/home/jason/webapps/introcart_devtools/introcart_wagtail/package.json'

and the build fails, however when installing node_modules or applying npm to build js/css, no complaint is made if I remove package-lock.json

jason@localhost:introcart_wagtail$ rm package-lock.json 
jason@localhost:introcart_wagtail$ npm run dev

I don't see any answer considering Grid-Css. I think it is a very elegant approach: grid-css even supports row span and and column spans. Here you can find a very good article:

https://medium.com/@js_tut/css-grid-tutorial-filling-in-the-gaps-c596c9534611

The Value of num will be some garbage value from the main memory(RAM). its better if you initialize the variable just after creating.

I did this:

$('#myModal').on 'shown.bs.modal', (e) ->  
  $(e.target).find('.modal-body').load('http://yourserver.com/content')

It can be as follows:

UPDATE A 
SET A.`id` = (SELECT id from B WHERE A.title = B.title)

Swift-5

Use intrinsicContentSize to find the text height and width.

yourLabel.intrinsicContentSize.width

This will work even you have custom spacing between your string like "T E X T"

There are some great suggestions here.

I think it's worth noting that you can treat an ActiveRecord model as a hash like so:

@customer = Customer.new( name: "John Jacob" )
@customer.name    # => "John Jacob"
@customer[:name]  # => "John Jacob"
@customer['name'] # => "John Jacob"

Therefore, instead of generating a hash of the attributes, you can use the object itself as a hash.

position: relative;
z-index: 2;
cursor: pointer

worked for me.

Maybe you should look into using something simple like a truecrypt volume for source code storage as that seems to be a concern of yours. You can create an encrypted file on a usb key or just encrypt the whole volume (provided the code will fit) so you can simply take the key with you at the end of the day.

To compile, you could then use something like PyInstaller or py2exe in order to create a stand-alone executable. If you really wanted to go the extra mile, look into a packer or compression utility in order to add more obfuscation. If none of these are an option, you could at least compile the script into bytecode so it isn't immediately readable. Keep in mind that these methods will merely slow someone trying to debug or decompile your program.

My educated guess is that the memory use you are seeing is not from the page content, but rather from loading UIWebView and all of it's supporting WebKit libraries. I love the UIWebView control, but it is a 'heavy' control that pulls in a very large block of code.

This code is a large sub-set of the iOS Safari browser, and likely initializes a large body of static structures.

I have finally found a workaround. The magic is hidden under the hood of the BluetoothDevice class (see https://github.com/android/platform_frameworks_base/blob/android-4.3_r2/core/java/android/bluetooth/BluetoothDevice.java#L1037).

Now, when I receive that exception, I instantiate a fallback BluetoothSocket, similar to the source code below. As you can see, invoking the hidden method createRfcommSocket via reflections. I have no clue why this method is hidden. The source code defines it as public though...

Class<?> clazz = tmp.getRemoteDevice().getClass();
Class<?>[] paramTypes = new Class<?>[] {Integer.TYPE};

Method m = clazz.getMethod("createRfcommSocket", paramTypes);
Object[] params = new Object[] {Integer.valueOf(1)};

fallbackSocket = (BluetoothSocket) m.invoke(tmp.getRemoteDevice(), params);
fallbackSocket.connect();

connect() then does not fail any longer. I have experienced a few issues still. Basically, this sometimes blocks and fails. Rebooting the SPP-Device (plug off / plug in) helps in such cases. Sometimes I also get another Pairing request after connect() even when the device is already bonded.

UPDATE:

here is a complete class, containing some nested classes. for a real implementation these could be held as seperate classes.

Interesting discussion. I was asking myself this question too. The main difference between fluid and fixed is simply that the fixed layout has a fixed width in terms of the whole layout of the website (viewport). If you have a 960px width viewport each colum has a fixed width which will never change.

The fluid layout behaves different. Imagine you have set the width of your main layout to 100% width. Now each column will only be calculated to it's relative size (i.e. 25%) and streches as the browser will be resized. So based on your layout purpose you can select how your layout behaves.

Here is a good article about fluid vs. flex.

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

in a bash script the following works:

#!/bin/sh

text="this is line one\nthis is line two\nthis is line three"
echo -e $text > filename

alternatively:

text="this is line one
this is line two
this is line three"
echo "$text" > filename

cat filename gives:

this is line one
this is line two
this is line three

group by default order by pk id,so the result
username point avg_time
demo123 100 90 ---> id = 4
demo123456 100 100 ---> id = 7
demo 90 120 ---> id = 1

I tried mipadi's answer and comments on playground. And thought of sharing it. Here you go. I think mipadi's answer should be mark as accepted.

class A{
    class func classFunction(){
    }
    static func staticFunction(){
    }
    class func classFunctionToBeMakeFinalInImmediateSubclass(){
    }
}

class B: A {
    override class func classFunction(){

    }

    //Compile Error. Class method overrides a 'final' class method
    override static func staticFunction(){

    }

    //Lets avoid the function called 'classFunctionToBeMakeFinalInImmediateSubclass' being overriden by subclasses

    /* First way of doing it
    override static func classFunctionToBeMakeFinalInImmediateSubclass(){
    }
    */

    // Second way of doing the same
    override final class func classFunctionToBeMakeFinalInImmediateSubclass(){
    }

    //To use static or final class is choice of style.
    //As mipadi suggests I would use. static at super class. and final class to cut off further overrides by a subclass
}

class C: B{
    //Compile Error. Class method overrides a 'final' class method
    override static func classFunctionToBeMakeFinalInImmediateSubclass(){

    }
}

$newstr = preg_replace('/[^a-zA-Z0-9\']/', '_', "There wouldn't be any");
$newstr = str_replace("'", '', $newstr);

I put them on two separate lines to make the code a little more clear.

Note: If you're looking for Unicode support, see Filip's answer below. It will match all characters that register as letters in addition to A-z.

Use this code:

Intent intent=new Intent(context,SecondActivty.class);
startActivity(intent);
finish();

context: refer to current activity context,

please make sure that you have added activity in android manifest file.

Following code for adding activity in android manifest file

<Activity name=".SecondActivity">
</Activity>

You have two options.

Option 1

Make the menu bar temporarily visible.

• press Alt key and you will be able to see the menu bar

Option 2

Make the menu bar permanently visible.

Steps:

1. Press F1
2. Type user settings
3. Press Enter
4. Click on the { } (top right corner of the window) to open settings.json file see the screenshot
5. Then in the settings.json file, change the value to the default "window.menuBarVisibility": "default" you can see a sample here (or remove this line from JSON file. If you remove any value from the settings.json file then it will use the default settings for those entries. So if you want to make everything to default settings then remove all entries in the settings.json file).

Dont know whether I should put this as answer or not...

I used @Zeeshan0026's solution to draw the path...and the problem was that if I draw path once, and then I do try to draw path once again, both two paths show and this continues...paths showing even when markers were deleted... while, ideally, old paths' shouldn't be there once new path is drawn / markers are deleted..

going through some other question over SO, I had the following solution

I add the following function in Zeeshan's class

 public void clearRoute(){

         for(Polyline line1 : polylines)
         {
             line1.remove();
         }

         polylines.clear();

     }

in my map activity, before drawing the path, I called this function.. example usage as per my app is

private Route rt;

rt.clearRoute();

            if (src == null) {
                Toast.makeText(getApplicationContext(), "Please select your Source", Toast.LENGTH_LONG).show();
            }else if (Destination == null) {
                Toast.makeText(getApplicationContext(), "Please select your Destination", Toast.LENGTH_LONG).show();
            }else if (src.equals(Destination)) {
                Toast.makeText(getApplicationContext(), "Source and Destinatin can not be the same..", Toast.LENGTH_LONG).show();
            }else{

                rt.drawRoute(mMap, MapsMainActivity.this, src,
                        Destination, false, "en");
            }

you can use rt.clearRoute(); as per your requirements.. Hoping that it will save a few minutes of someone else and will help some beginner in solving this issue..

    <ng-include src="'views/sidepanel.html'"></ng-include>

OR

    <div ng-include="'views/sidepanel.html'"></div>

OR

    <div ng-include src="'views/sidepanel.html'"></div>

Points To Remember:

--> No spaces in src

--> Remember to use single quotation in double quotation for src

To answer your second query re. how encoding works, Joel Spolsky wrote a great introductory article on this. Strongly recommended.

For sure: qsort() is an implementation of a sort (not necessarily quicksort as its name might suggest).

Try man 3 qsort or have a read at http://linux.die.net/man/3/qsort

You have 2 cases

• If you create Makefile by yourself, go to

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Disable generate makefile automatically -> Under the Builder Settings tab on the right, check and make sure the "Build location" is correct (That location is where your Makefile)

• If you don't have Makefile -> You need Eclipse DS-5 to help you create Makefile

1. Select Project->Properties from the menu bar.
2. Click C/C++ Build on the left in the dialog that comes up.
3. Enable generate makefile automatically

I advise you create Makefile by your self

CSS solutions not working properly on touch device

I found that any CSS solutions made the menu stay open on touch devices, they didn't collapse anymore.

So I read the article: https://www.brianshim.com/webtricks/drop-down-menus-on-ios-and-android/ (by Brian Shim)
Very useful! It states that a touch device always first checks the existence of a hover class on an element.

But: by using jQuery .show() you introduce a style attribute (display:block;) that makes the menu open up on first touch. Now the menu has opened without the bootstrap 'show' class. If a user chooses a link from the dropdown menu it works perfectly. But if a user decides to close the menu without using it he has to tap twice to close the menu: At the first tap the original bootstrap 'show' class gets attached so the menu opens up again, at the second tap the menu closes due to normal bootstrap behaviour (removal of 'show' class).

To prevent this I used the article: https://codeburst.io/the-only-way-to-detect-touch-with-javascript-7791a3346685 (by David Gilbertson)

He has some very handy ways of detecting touch or hover devices.

So, combined the two authors with a bit jQuery of my own:

$(window).one('mouseover', function(){
      window.USER_CAN_HOVER = true;
      if(USER_CAN_HOVER){
          jQuery('#navbarNavDropdown ul li.dropdown').on("mouseover", function() {
             var $parent = jQuery(this);
             var $dropdown = $parent.children('ul');

             $dropdown.show(200,function() { 
               $parent.mouseleave(function() {
                 var $this = jQuery(this);
                 $this.children('ul').fadeOut(200);
               });
             });
          });
      };

}); Check once if a device allows a hover event. If it does, introduce the possibility to hover using .show(). If the device doesn't allow a hover event, the .show() never gets introduced so you get natural bootstrap behaviour on touch device.

Be sure to remove any CSS regarding menu hover classes.

Took me three days :) so I hope it helps some of you.

Edit /etc/conf.apf. Set DEVEL_MODE="0". DEVEL_MODE set to 1 will add a cron job to stop apf after 5 minutes.

If one is used to work with DLL in Windows and would like to skip .so version numbers in linux/QT, adding CONFIG += plugin will take version numbers out. To use absolute path to .so, giving it to linker works fine, as Mr. Klatchko mentioned.

If you have an ejected create-react-app, I would suggest:

1. Create a new React app through create-react-app.
2. Eject it through npm run eject or yarn eject.
3. Install all the packages that are missing from the package.json.
4. Copy your src folder assuming all your code is situated in this folder.
5. Redo your changes on the config and script folders, if needed.

Worked for me.

The Exception means that the socket was closed unexpectedly from the other side. Since you are calling a web service, this should not happen - most likely you're sending a request that triggers a bug in the web service.

Try logging the entire request in those cases, and see if you notice anything unusual. Otherwise, get in contact with the web service provider and send them your logged problematical request.

You need to add a name attribute to your dropdown list, then you need to add a required attribute, and then you can reference the error using myForm.[input name].$error.required:

HTML:

        <form name="myForm" ng-controller="Ctrl" ng-submit="save(myForm)" novalidate>
        <input type="text" name="txtServiceName" ng-model="ServiceName" required>
<span ng-show="myForm.txtServiceName.$error.required">Enter Service Name</span>
<br/>
          <select name="service_id" class="Sitedropdown" style="width: 220px;"          
                  ng-model="ServiceID" 
                  ng-options="service.ServiceID as service.ServiceName for service in services"
                  required> 
            <option value="">Select Service</option> 
          </select> 
          <span ng-show="myForm.service_id.$error.required">Select service</span>

        </form>

    Controller:

        function Ctrl($scope) {
          $scope.services = [
            {ServiceID: 1, ServiceName: 'Service1'},
            {ServiceID: 2, ServiceName: 'Service2'},
            {ServiceID: 3, ServiceName: 'Service3'}
          ];

    $scope.save = function(myForm) {
    console.log('Selected Value: '+ myForm.service_id.$modelValue);
    alert('Data Saved! without validate');
    };
        }

Here's a working plunker.

You could use if(number >= 0). The fact that you use int number = input.nextInt(); makes sure that it has to be an Integer.

Basically I was trying to get my code to have a middle section on a 'row' to auto-adjust to the content on both sides (in my case, a dotted line separator). Like @Michael_B suggested, the key is using display:flex on the row container and at least making sure your middle container on the row has a flex-grow value of at least 1 higher than the outer containers (if outer containers don't have any flex-grow properties applied, middle container only needs 1 for flex-grow).

Here's a pic of what I was trying to do and sample code for how I solved it.

.row {
  background: lightgray;
  height: 30px;
  width: 100%;
  display: flex;
  align-items:flex-end;
  margin-top:5px;
}
.left {
  background:lightblue;
}
.separator{
  flex-grow:1;
  border-bottom:dotted 2px black;
}
.right {
  background:coral;
}

<div class="row">
  <div class="left">Left</div>
  <div class="separator"></div>
  <div class="right">Right With Text</div>
</div>
<div class="row">
  <div class="left">Left With More Text</div>
  <div class="separator"></div>
  <div class="right">Right</div>
</div>
<div class="row">
  <div class="left">Left With Text</div>
  <div class="separator"></div>
  <div class="right">Right With More Text</div>
</div>

i use it like this:

printf("my number is 0x%02X\n",number);
// output: my number is 0x4A

Just change number "2" to any number of chars You want to print ;)

Your .mobile div has the following styles on it:

.mobile {
    display: none !important;
    visibility: hidden !important;
}

Therefore you need to override the visibility property with visible in addition to overriding the display property with block. Like so:

.visible-sm {
    display: block !important;
    visibility: visible !important;
}

Not perfect but best solution for now :

var spcKey = false;
var hover = true;
var contextMenu = false;

function spc(e) {
    return ((e.altKey || e.ctrlKey || e.keyCode == 91 || e.keyCode==87) && e.keyCode!=82 && e.keyCode!=116);
}

$(document).hover(function () {
    hover = true;
    contextMenu = false;
    spcKey = false;
}, function () {
    hover = false;
}).keydown(function (e) {
    if (spc(e) == false) {
        hover = true;
        spcKey = false;
    }
    else {
        spcKey = true;
    }
}).keyup(function (e) {
    if (spc(e)) {
        spcKey = false;
    }
}).contextmenu(function (e) {
    contextMenu = true;
}).click(function () {
    hover = true;
    contextMenu = false;
});

window.addEventListener('focus', function () {
    spcKey = false;
});
window.addEventListener('blur', function () {
    hover = false;
});

window.onbeforeunload = function (e) {
    if ((hover == false || spcKey == true) && contextMenu==false) {
        window.setTimeout(goToLoginPage, 100);
        $.ajax({
            url: "/Account/Logoff",
            type: 'post',
            data: $("#logoutForm").serialize(),
        });
        return "Oturumunuz kapatildi.";
    }
    return;
};

function goToLoginPage() {
    hover = true;
    spcKey = false;
    contextMenu = false;
    location.href = "/Account/Login";
}

If you want a pretty, multiline JSON with indentation then you can use JSON.stringify with its 3rd argument:

JSON.stringify(value[, replacer[, space]])

For example:

var obj = {a:1,b:2,c:{d:3, e:4}};

JSON.stringify(obj, null, "    ");

or

JSON.stringify(obj, null, 4);

will give you following result:

"{
    "a": 1,
    "b": 2,
    "c": {
        "d": 3,
        "e": 4
    }
}"

In a browser console.log(obj) does even better job, but in a shell console (node.js) it doesn't.

This is now no longer needed for Java 9, nor for any recent release of Java 6, 7, or 8. Finally! :)

Per JDK-8170157, the unlimited cryptographic policy is now enabled by default.

Specific versions from the JIRA issue:

• Java 9 (10, 11, etc..): Any official release!
• Java 8u161 or later (Available now)
• Java 7u171 or later (Only available through 'My Oracle Support')
• Java 6u181 or later (Only available through 'My Oracle Support')

Note that if for some odd reason the old behavior is needed in Java 9, it can be set using:

Security.setProperty("crypto.policy", "limited");

In regards to testing if a module you are utilizing is secure or not there are several routes you can take. I will touch on the pros/cons of each so you can make a more informed decision.

Currently, there aren't any vulnerabilities for the module you are utilizing, however, this can often lead to a false sense of security as there very well could be a vulnerability currently exploiting the module/software package you are using and you wouldn't be alerted to a problem until the vendor applies a fix/patch.

1. To keep abreast of vulnerabilities you will need to follow mailing lists, forums, IRC & other hacking related discussions. PRO: You can often times you will become aware of potential problems within a library before a vendor has been alerted or has issued a fix/patch to remedy the potential avenue of attack on their software. CON: This can be very time consuming and resource intensive. If you do go this route a bot using RSS feeds, log parsing (IRC chat logs) and or a web scrapper using key phrases (in this case node-mysql-native) and notifications can help reduce time spent trolling these resources.

2. Create a fuzzer, use a fuzzer or other vulnerability framework such as metasploit, sqlMap etc. to help test for problems that the vendor may not have looked for. PRO: This can prove to be a sure fire method of ensuring to an acceptable level whether or not the module/software you are implementing is safe for public access. CON: This also becomes time consuming and costly. The other problem will stem from false positives as well as uneducated review of the results where a problem resides but is not noticed.

Really security, and application security in general can be very time consuming and resource intensive. One thing managers will always use is a formula to determine the cost effectiveness (manpower, resources, time, pay etc) of performing the above two options.

Anyways, I realize this is not a 'yes' or 'no' answer that may have been hoping for but I don't think anyone can give that to you until they perform an analysis of the software in question.

I am working through the same need and I believe your timeframe is incorrect.

Try these:

• 15min change: find . -mtime -.01
• 1hr change: find . -mtime -.04
• 12 hr change: find . -mtime -.5

You should be using 24 hours as your base. The number after -mtime should be relative to 24 hours. Thus -.5 is the equivalent of 12 hours, because 12 hours is half of 24 hours.

String space = String.format("%"+ numberOfSpaces +"s", " ");

If you have a number, for example 65, and if you want to get the corresponding ASCII character, you can use the chr function, like this

>>> chr(65)
'A'

similarly if you have 97,

>>> chr(97)
'a'

EDIT: The above solution works for 8 bit characters or ASCII characters. If you are dealing with unicode characters, you have to specify unicode value of the starting character of the alphabet to ord and the result has to be converted using unichr instead of chr.

>>> print unichr(ord(u'\u0B85'))
?

>>> print unichr(1 + ord(u'\u0B85'))
?

NOTE: The unicode characters used here are of the language called "Tamil", my first language. This is the unicode table for the same http://www.unicode.org/charts/PDF/U0B80.pdf

Do this:

<ToggleButton 
        android:id="@+id/toggle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/check"   <!--check.xml-->
        android:layout_margin="10dp"
        android:textOn=""
        android:textOff=""
        android:focusable="false"
        android:focusableInTouchMode="false"
        android:layout_centerVertical="true"/>

create check.xml in drawable folder

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/selected_image"
          android:state_checked="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/unselected_image"
        android:state_checked="false"/>

 </selector>

I know this is an old question but according what @mikejones1477 said, modern front end libraries and frameworks escape the text giving you protection against XSS. The reason why cookies are not a secure method using credentials is that cookies doesn't prevent CSRF when localStorage does (also remember that cookies are accessible by javascript too, so XSS isn't the big problem here), this answer resume why.

The reason storing an authentication token in local storage and manually adding it to each request protects against CSRF is that key word: manual. Since the browser is not automatically sending that auth token, if I visit evil.com and it manages to send a POST http://example.com/delete-my-account, it will not be able to send my authn token, so the request is ignored.

Of course httpOnly is the holy grail but you can't access from reactjs or any js framework beside you still have CSRF vulnerability. My recommendation would be localstorage or if you want to use cookies make sure implemeting some solution to your CSRF problem like django does.

Regarding with the CDN's make sure you're not using some weird CDN, for example CDN like google or bootstrap provide, are maintained by the community and doesn't contain malicious code, if you are not sure, you're free to review.

man curl:

   -H/--header <header>
          (HTTP)  Extra header to use when getting a web page. You may specify
          any number of extra headers. Note that if you should  add  a  custom
          header that has the same name as one of the internal ones curl would
          use, your externally set header will be used instead of the internal
          one.  This  allows  you  to make even trickier stuff than curl would
          normally do. You should not replace internally set  headers  without
          knowing  perfectly well what you're doing. Remove an internal header
          by giving a replacement without content on the  right  side  of  the
          colon, as in: -H "Host:".

          curl  will  make sure that each header you add/replace get sent with
          the proper end of line marker, you should thus not  add  that  as  a
          part  of the header content: do not add newlines or carriage returns
          they will only mess things up for you.

          See also the -A/--user-agent and -e/--referer options.

          This option can be used multiple times to add/replace/remove  multi-
          ple headers.

Example:

curl --header "X-MyHeader: 123" www.google.com

You can see the request that curl sent by adding the -v option.

You don't need to prevent this error message!
Error messages are your friends!
Without error message you'd never know what is happened.
It's all right! Any working code supposed to throw out error messages.

Though error messages needs proper handling. Usually you don't have to to take any special actions to avoid such an error messages. Just leave your code intact. But if you don't want this error message to be shown to the user, just turn it off. Not error message itself but daislaying it to the user.

ini_set('display_errors',0);
ini_set('log_errors',1);

or even better at .htaccess/php.ini level
And user will never see any error messages. While you will be able still see it in the error log.
Please note that error_reporting should be at max in both cases.

To prevent this message you can check mysql_query result and run fetch_assoc only on success.
But usually nobody uses it as it may require too many nested if's.
But there can be solution too - exceptions!

But it is still not necessary. You can leave your code as is, because it is supposed to work without errors when done.

Using return is another method to avoid nested error messages. Here is a snippet from my database handling function:

  $res = mysql_query($query);
  if (!$res) {
    trigger_error("dbget: ".mysql_error()." in ".$query);
    return false;
  }
  if (!mysql_num_rows($res)) return NULL;

  //fetching goes here
  //if there was no errors only

You can try this

select count( distinct pos) from
(select instr('123-456-789', '-', level) as pos from dual
  connect by level <=length('123-456-789'))
where nvl(pos, 0) !=0

it counts "properly" olso for how many 'aa' in 'bbaaaacc'

select count( distinct pos) from
(select instr('bbaaaacc', 'aa', level) as pos from dual
  connect by level <=length('bbaaaacc'))
where nvl(pos, 0) !=0

It passes control to the next matching route. In the example you give, for instance, you might look up the user in the database if an id was given, and assign it to req.user.

Below, you could have a route like:

app.get('/users', function(req, res) {
  // check for and maybe do something with req.user
});

Since /users/123 will match the route in your example first, that will first check and find user 123; then /users can do something with the result of that.

Route middleware is a more flexible and powerful tool, though, in my opinion, since it doesn't rely on a particular URI scheme or route ordering. I'd be inclined to model the example shown like this, assuming a Users model with an async findOne():

function loadUser(req, res, next) {
  if (req.params.userId) {
    Users.findOne({ id: req.params.userId }, function(err, user) {
      if (err) {
        next(new Error("Couldn't find user: " + err));
        return;
      }

      req.user = user;
      next();
    });
  } else {
    next();
  }
}

// ...

app.get('/user/:userId', loadUser, function(req, res) {
  // do something with req.user
});

app.get('/users/:userId?', loadUser, function(req, res) {
  // if req.user was set, it's because userId was specified (and we found the user).
});

// Pretend there's a "loadItem()" which operates similarly, but with itemId.
app.get('/item/:itemId/addTo/:userId', loadItem, loadUser, function(req, res) {
  req.user.items.append(req.item.name);
});

Being able to control flow like this is pretty handy. You might want to have certain pages only be available to users with an admin flag:

/**
 * Only allows the page to be accessed if the user is an admin.
 * Requires use of `loadUser` middleware.
 */
function requireAdmin(req, res, next) {
  if (!req.user || !req.user.admin) {
    next(new Error("Permission denied."));
    return;
  }

  next();
}

app.get('/top/secret', loadUser, requireAdmin, function(req, res) {
  res.send('blahblahblah');
});

Hope this gave you some inspiration!

I had the same problem, USB debugging enabled, device showing up in windows but I never got the question about RSA fingerprint when I connected my Nexus (6) device, nor did it show up in the Android Device Manager.

BUT In the windows device manager I did have an entry saying it was an android device and Composite ADB interface etc. Still didn't work. When I tried the previous tips about manually updating the drivers, Windows 8.1 just responded that "Windows has determined that the driver software for your device is up to date" this was not true. Looking at the driver details I saw that the driver was published by "ClockworkMod". I realized this must be because I had installed the Helium app sometime last year. So I uninstalled that, still had the same problem. Checked again, this time it was indeed google drivers, but version 7 published in 2012 (and not version 11 published 2014). I uninstalled these AS WELL and then tried the trick of reinstalling the driver from the SDK located in: %localappdata%\Android\sdk\extras\google\usb_driver

Now when I replugged my device it finally works and can be debugged with Android Studio. Indeed a driver problem.

If it's in the same class with the equal number of parameters with the same types and order, then it is not possible for example:

int methoda(String a,int b) {
        return b;
}
String methoda(String b,int c) {
        return b;    
}

if the number of parameters and their types is same but order is different then it is possible since it results in method overloading. It means if the method signature is same which includes method name with number of parameters and their types and the order they are defined.

To end the program, you should be using Ctrl + C. If you do that, it sends SIGINT, which allows the program to end gracefully, unbinding from any ports it is listening on.

After creating virtual environment copy the activate.bat file from Script folder of python and paste to it your environment and open cmd from your virtual environment and run activate.bat file.enter image description here

In the past, I've used a .cmd script I found on the Internet. I hate the way localization normally messes with dates. Anytime you have dates in filenames (or anywhere else, if I may be so bold) I figure you want them in ISO 8601 format:

2015-02-19T14:54:51Z

or something else that has Y M D H M in that order, such as

2015-02-19 14:54

because it fixes the MDY / DMY ambiguity and because it's sortable as text.

I don't know where I got that .cmd script, but it may have been http://ss64.com/nt/syntax-getdate.html, which works beautifully on my YYYY-MM-DD Windows 8.1 and on a M/D/YYYY vanilla install of Windows 7. Both give the same format:

2015-02-09 04:43

My code, it work for me, I use localStorage HTML5

$('#tabHistory  a').click(function(e) {
  e.preventDefault();
  $(this).tab('show');
});
$("ul.nav-tabs#tabHistory > li > a").on("shown.bs.tab", function(e) {
  var id = $(e.target).attr("href");
  localStorage.setItem('selectedTab', id)
});
var selectedTab = localStorage.getItem('selectedTab');
$('#tabHistory a[href="' + selectedTab + '"]').tab('show');

you can use just

In my case, I had executed permissions and I couldn't run gradlew even with sudo. my problem was my project was in another hard drive and I didn't have exec permission on that drive. I simply removed noexec mount flag from fstab and added exec flag. then remount the disk so changes apply.

to_string() is only present in c++11 so if c++ version is less use some alternate methods such as sprintf or ostringstream

You may use ViewModel object in your activity.

ViewModel objects are automatically retained during configuration changes so that data they hold is immediately available to the next activity or fragment instance. Read more:

I was recently struggling with a similar problem. It turned out that the database was missing indexes on foreign keys. That caused Oracle to lock many more records than required which quickly led to a deadlock during high concurrency.

Here is an excellent article with lots of good detail, suggestions, and details about how to fix a deadlock: http://www.oratechinfo.co.uk/deadlocks.html#unindex_fk

hymloth and sven's answers work, but they do not modify the list (the create a new one). If you need the object modification you need to assign to a slice:

x[:] = [value for value in x if len(value)==2]

However, for large lists in which you need to remove few elements, this is memory consuming, but it runs in O(n).

glglgl's answer suffers from O(n²) complexity, because list.remove is O(n).

Depending on the structure of your data, you may prefer noting the indexes of the elements to remove and using the del keywork to remove by index:

to_remove = [i for i, val in enumerate(x) if len(val)==2]
for index in reversed(to_remove): # start at the end to avoid recomputing offsets
    del x[index]

Now del x[i] is also O(n) because you need to copy all elements after index i (a list is a vector), so you'll need to test this against your data. Still this should be faster than using remove because you don't pay for the cost of the search step of remove, and the copy step cost is the same in both cases.

[edit] Very nice in-place, O(n) version with limited memory requirements, courtesy of @Sven Marnach. It uses itertools.compress which was introduced in python 2.7:

from itertools import compress

selectors = (len(s) == 2 for s in x)
for i, s in enumerate(compress(x, selectors)): # enumerate elements of length 2
    x[i] = s # move found element to beginning of the list, without resizing
del x[i+1:]  # trim the end of the list

Since the count is the intended final value, in your query pass

$this->db->distinct();
$this->db->select('accessid');
$this->db->where('record', $record); 
$query = $this->db->get()->result_array();
return count($query);

The count the retuned value

My requirements are the camera preview need to be fullscreen and keep the aspect ratio. Hesam and Yoosuf's solution was great but I do see a high zoom problem for some reason.

The idea is the same, have the preview container center in parent and increase the width or height depend on the aspect ratios until it can cover the entire screen.

One thing to note is the preview size is in landscape because we set the display orientation.

camera.setDisplayOrientation(90);

The container that we will add the SurfaceView view to:

<RelativeLayout
    android:id="@+id/camera_preview_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"/>

Add the preview to it's container with center in parent in your activity.

this.cameraPreview = new CameraPreview(this, camera);
cameraPreviewContainer.removeAllViews();
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
    ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
cameraPreviewContainer.addView(cameraPreview, 0, params);

Inside the CameraPreview class:

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
    // If your preview can change or rotate, take care of those events here.
    // Make sure to stop the preview before resizing or reformatting it.

    if (holder.getSurface() == null) {
        // preview surface does not exist
        return;
    }

    stopPreview();

    // set preview size and make any resize, rotate or
    // reformatting changes here
    try {
        Camera.Size nativePictureSize = CameraUtils.getNativeCameraPictureSize(camera);
        Camera.Parameters parameters = camera.getParameters();
        parameters.setPreviewSize(optimalSize.width, optimalSize.height);
        parameters.setPictureSize(nativePictureSize.width, nativePictureSize.height);
        camera.setParameters(parameters);
        camera.setDisplayOrientation(90);
        camera.setPreviewDisplay(holder);
        camera.startPreview();

    } catch (Exception e){
        Log.d(TAG, "Error starting camera preview: " + e.getMessage());
    }
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int width = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec);
    final int height = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec);

    if (supportedPreviewSizes != null && optimalSize == null) {
        optimalSize = CameraUtils.getOptimalSize(supportedPreviewSizes, width, height);
        Log.i(TAG, "optimal size: " + optimalSize.width + "w, " + optimalSize.height + "h");
    }

    float previewRatio =  (float) optimalSize.height / (float) optimalSize.width;
    // previewRatio is height/width because camera preview size are in landscape.
    float measuredSizeRatio = (float) width / (float) height;

    if (previewRatio >= measuredSizeRatio) {
        measuredHeight = height;
        measuredWidth = (int) ((float)height * previewRatio);
    } else {
        measuredWidth = width;
        measuredHeight = (int) ((float)width / previewRatio);
    }
    Log.i(TAG, "Preview size: " + width + "w, " + height + "h");
    Log.i(TAG, "Preview size calculated: " + measuredWidth + "w, " + measuredHeight + "h");

    setMeasuredDimension(measuredWidth, measuredHeight);
}

While that particular idiom is common, even more common is for people to use = when they mean ==. The convention when you really mean the = is to use an extra layer of parentheses:

while ((list = list->next)) { // yes, it's an assignment

Here is the official answer from Microsoft: http://blogs.msdn.com/b/chuckw/archive/2011/12/09/known-issue-directx-sdk-june-2010-setup-and-the-s1023-error.aspx

Summary if you'd rather not click through:

1. Remove the Visual C++ 2010 Redistributable Package version 10.0.40219 (Service Pack 1) from the system (both x86 and x64 if applicable). This can be easily done via a command-line with administrator rights:

   MsiExec.exe /passive /X{F0C3E5D1-1ADE-321E-8167-68EF0DE699A5}

   MsiExec.exe /passive /X{1D8E6291-B0D5-35EC-8441-6616F567A0F7}

2. Install the DirectX SDK (June 2010)

3. Reinstall the Visual C++ 2010 Redistributable Package version 10.0.40219 (Service Pack 1). On an x64 system, you should install both the x86 and x64 versions of the C++ REDIST. Be sure to install the most current version available, which at this point is the KB2565063 with a security fix.

Windows SDK: The Windows SDK 7.1 has exactly the same issue as noted in KB 2717426.

It is possible to get this working in VS Code and have the Cmder terminal be integrated (not pop up).

To do so:

1. Create an environment variable "CMDER_ROOT" pointing to your Cmder directory.
2. In (Preferences > User Settings) in VS Code add the following settings:

"terminal.integrated.shell.windows": "cmd.exe"

"terminal.integrated.shellArgs.windows": ["/k", "%CMDER_ROOT%\\vendor\\init.bat"]

@@ROWCOUNT will give the number of rows affected by the last SQL statement, it is best to capture it into a local variable following the command in question, as its value will change the next time you look at it:

DECLARE @Rows int
DECLARE @TestTable table (col1 int, col2 int)
INSERT INTO @TestTable (col1, col2) select 1,2 union select 3,4
SELECT @Rows=@@ROWCOUNT
SELECT @Rows AS Rows,@@ROWCOUNT AS [ROWCOUNT]

OUTPUT:

(2 row(s) affected)
Rows        ROWCOUNT
----------- -----------
2           1

(1 row(s) affected)

you get Rows value of 2, the number of inserted rows, but ROWCOUNT is 1 because the SELECT @Rows=@@ROWCOUNT command affected 1 row

if you have multiple INSERTs or UPDATEs, etc. in your transaction, you need to determine how you would like to "count" what is going on. You could have a separate total for each table, a single grand total value, or something completely different. You'll need to DECLARE a variable for each total you want to track and add to it following each operation that applies to it:

--note there is no error handling here, as this is a simple example
DECLARE @AppleTotal  int
DECLARE @PeachTotal  int

SELECT @AppleTotal=0,@PeachTotal=0

BEGIN TRANSACTION

INSERT INTO Apple (col1, col2) Select col1,col2 from xyz where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT

INSERT INTO Apple (col1, col2) Select col1,col2 from abc where ...
SET @AppleTotal=@AppleTotal+@@ROWCOUNT

INSERT INTO Peach (col1, col2) Select col1,col2 from xyz where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT

INSERT INTO Peach (col1, col2) Select col1,col2 from abc where ...
SET @PeachTotal=@PeachTotal+@@ROWCOUNT

COMMIT

SELECT @AppleTotal AS AppleTotal, @PeachTotal AS PeachTotal

Just put quotes around the Environment variable (as you have done) :
if "%DevEnvDir%" == "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\"
but it's the way you put opening bracket without a space that is confusing it.

Works for me...

C:\if "%gtk_basepath%" == "C:\Program Files\GtkSharp\2.12\" (echo yes)
yes

Here is how I do this: http://jsfiddle.net/Zz7Wq/2/

I use a background instead of after and use my H1 or H2 to cover the background. Not quite your method above but does work well for me.

CSS

.title-box { background: #fff url('images/bar-orange.jpg') repeat-x left; text-align: left; margin-bottom: 20px;}
.title-box h1 { color: #000; background-color: #fff; display: inline; padding: 0 50px 0 50px; }

HTML

<div class="title-box"><h1>Title can go here</h1></div>
<div class="title-box"><h1>Title can go here this one is really really long</h1></div>

In my case, the orderBy is determined by a select box. I prefer Ludwig's response because you can set the sort direction in the select options as such:

        $scope.options = [
            { label: 'Title', value: 'title' },
            { label: 'Newest', value: '-publish_date' },
            { label: 'Featured', value: '-featured' }
        ]; 

markup:

<select ng-model="orderProp" ng-options="opt as opt.label for opt in options"></select>
<ul>
    <li ng-repeat="item in items | orderBy:orderProp.value"></li>
</ul>

Declare in your Model with

  [DataType(DataType.MultilineText)]
  public string urString { get; set; }

Then in .cshtml can make use of editor as below. you can make use of @cols and @rows for TextArea size

     @Html.EditorFor(model => model.urString, new { htmlAttributes = new { @class = "",@cols = 35, @rows = 3 } })

Thanks !

There is no such functionality but you can use a temporary file by File.createTempFile().

File temp = File.createTempFile(prefix, suffix);
// tell system to delete it when vm terminates.
temp.deleteOnExit();

This also works. 

fieldset {
  width:0px;

The answers provided did not work for me (Chrome or Firefox) while creating PWA for local development and testing. DO NOT USE FOR PRODUCTION! I was able to use the following:

1. Online certificate tools site with the following options:
   • Common Names: Add both the "localhost" and IP of your system e.g. 192.168.1.12
   • Subject Alternative Names: Add "DNS" = "localhost" and "IP" = <your ip here, e.g. 192.168.1.12>
   • "CRS" drop down options set to "Self Sign"
   • all other options were defaults
2. Download all links
3. Import .p7b cert into Windows by double clicking and select "install"/ OSX?/Linux?
4. Added certs to node app... using Google's PWA example
   • add const https = require('https'); const fs = require('fs'); to the top of the server.js file
   • comment out return app.listen(PORT, () => { ... }); at the bottom of server.js file
   • add below https.createServer({ key: fs.readFileSync('./cert.key','utf8'), cert: fs.readFileSync('./cert.crt','utf8'), requestCert: false, rejectUnauthorized: false }, app).listen(PORT)

I have no more errors in Chrome or Firefox

Simply declare your variable outside any function:

globalValue = 1

def f(x):
    print(globalValue + x)

If you need to assign to the global from within the function, use the global statement:

def f(x):
    global globalValue
    print(globalValue + x)
    globalValue += 1

This article on jordanhollinger.com is the best option I feel. Similar to Razor's answer but a bit clearer. Code below; full credits to Jordan Hollinger:

Page before:

<a href="/page-of-no-return.htm#no-back>You can't go back from the next page</a>

Page of no return's JavaScript:

// It works without the History API, but will clutter up the history
var history_api = typeof history.pushState !== 'undefined'

// The previous page asks that it not be returned to
if ( location.hash == '#no-back' ) {
  // Push "#no-back" onto the history, making it the most recent "page"
  if ( history_api ) history.pushState(null, '', '#stay')
  else location.hash = '#stay'

  // When the back button is pressed, it will harmlessly change the url
  // hash from "#stay" to "#no-back", which triggers this function
  window.onhashchange = function() {
    // User tried to go back; warn user, rinse and repeat
    if ( location.hash == '#no-back' ) {
      alert("You shall not pass!")
      if ( history_api ) history.pushState(null, '', '#stay')
      else location.hash = '#stay'
    }
  }
}

You can use pm2

https://pm2.keymetrics.io/docs/usage/quick-start/

after installation just type in terminal

pm2 start app.js and then

pm2 stop 0 to stop your server

Just to keep a default value of the variable. Press Enter to use default from the recent run of your .bat:

@echo off
set /p Var1=<Var1.txt
set /p Var1="Enter new value ("%Var1%") "
echo %Var1%> Var1.txt

rem YourApp %Var1%

In the first run just ignore the message about lack of file with the initial value of the variable (or do create the Var1.txt manually).

I was also facing the same issue where I was receiving the Transaction_Date as YYYYMMDD in bigint format. So I converted it into Datetime format using below query and saved it in new column with datetime format. I hope this will help you as well.

SELECT
convert( Datetime, STUFF(STUFF(Transaction_Date, 5, 0, '-'), 8, 0, '-'), 120) As [Transaction_Date_New]
FROM mydb

I am trying to check if a key exist in an array in angular way and landed here on this question. In my Angularjs 1.4 ternary operator worked like below

{{ CONDITION ? TRUE : FALSE }}

hence for the array key exist i did a simple JS check

Solution 1 : {{ array['key'] !== undefined ? array['key'] : 'n/a' }}

Solution 2 : {{ "key" in array ? array['key'] : 'n/a' }}

While searching for doc to point to about how pragma are directives for the compiler, I found this NSHipster article that does the job pretty well.

I hope you'll enjoy the reading

For output only on error:

so [command]

1. Open the Command Palette

   Ctrl + Shift + P

2. Then type:

   Reload Window
   

Just set
mWebView.setWebChromeClient(new WebChromeClient());

and video plays as normally wont need any custom view.

Try this:

<add name="Access-Control-Allow-Origin" value="['URL1','URL2',...]" />

I had the same problem but also wanted to get the content of the file (after the YAML front-matter).

This is the best solution I have found:

if (md = contents.match(/^(?<metadata>---\s*\n.*?\n?)^(---\s*$\n?)/m))
  self.contents = md.post_match
  self.metadata = YAML.load(md[:metadata])
end
