calculate the height of each link no do this

document.getElementById("products").style.height= height_of_each_link* no_of_link

This issue occurs due to openssl and extension director so uncomment below extensions in php.ini file

extension=php_openssl.dll

extension_dir = "ext"

Its works on my machine.

You should include a path to your command, since cron runs with an extensively cut-down environment. You won't have all the environment variables you have in your interactive shell session.

It's a good idea to specify an absolute path to your script/binary, or define PATH in the crontab itself. To help debug any issues I would also redirect stdout/err to a log file.

var $div = $('<div />').appendTo('body');
$div.attr('id', 'holdy');

>>> d = {}
>>> D = set()
>>> type(d)
<type 'dict'>
>>> type(D)
<type 'set'>

What you've made is a dictionary and not a Set.

The update method in dictionary is used to update the new dictionary from a previous one, like so,

>>> abc = {1: 2}
>>> d.update(abc)
>>> d
{1: 2}

Whereas in sets, it is used to add elements to the set.

>>> D.update([1, 2])
>>> D
set([1, 2])

If above solutions are not working for your TextView then this will definitely work:

1. add this style

<style name="ClickableView">
    <item name="colorControlHighlight">@android:color/white</item>
    <item name="android:background">?selectableItemBackground</item>
</style>

2. use it just by

android:theme="@style/ClickableView"

you should use this code:

$json = json_encode(array_map('utf8_encode', $arr))

array_map function converts special characters in UTF8 standard

Some gotchas to watch out for:

If you double-click the batch file %0 will be surrounded by quotes. For example, if you save this file as c:\test.bat:

@echo %0
@pause

Double-clicking it will open a new command prompt with output:

"C:\test.bat"

But if you first open a command prompt and call it directly from that command prompt, %0 will refer to whatever you've typed. If you type test.batEnter, the output of %0 will have no quotes because you typed no quotes:

c:\>test.bat
test.bat

If you type testEnter, the output of %0 will have no extension too, because you typed no extension:

c:\>test
test

Same for tEsTEnter:

c:\>tEsT
tEsT

If you type "test"Enter, the output of %0 will have quotes (since you typed them) but no extension:

c:\>"test"
"test"

Lastly, if you type "C:\test.bat", the output would be exactly as though you've double clicked it:

c:\>"C:\test.bat"
"C:\test.bat"

Note that these are not all the possible values %0 can be because you can call the script from other folders:

c:\some_folder>/../teST.bAt
/../teST.bAt

All the examples shown above will also affect %~0, because the output of %~0 is simply the output of %0 minus quotes (if any).

As of npm@5, the npm cache self-heals from corruption issues and data extracted from the cache is guaranteed to be valid. If you want to make sure everything is consistent, use npm cache verify instead. On the other hand, if you're debugging an issue with the installer, you can use npm install --cache /tmp/empty-cache to use a temporary cache instead of nuking the actual one.

If you're sure you want to delete the entire cache, rerun:

npm cache clean --force

A complete log of this run can be found in /Users/USERNAME/.npm/_logs/2019-01-08T21_29_30_811Z-debug.log.

You might want to create static class which will contain all the fonts. That way, you won't create the font multiple times which might impact badly on performance. Just make sure that you create a sub-folder called "fonts" under "assets" folder.

Do something like:

public class CustomFontsLoader {

public static final int FONT_NAME_1 =   0;
public static final int FONT_NAME_2 =   1;
public static final int FONT_NAME_3 =   2;

private static final int NUM_OF_CUSTOM_FONTS = 3;

private static boolean fontsLoaded = false;

private static Typeface[] fonts = new Typeface[3];

private static String[] fontPath = {
    "fonts/FONT_NAME_1.ttf",
    "fonts/FONT_NAME_2.ttf",
    "fonts/FONT_NAME_3.ttf"
};


/**
 * Returns a loaded custom font based on it's identifier. 
 * 
 * @param context - the current context
 * @param fontIdentifier = the identifier of the requested font
 * 
 * @return Typeface object of the requested font.
 */
public static Typeface getTypeface(Context context, int fontIdentifier) {
    if (!fontsLoaded) {
        loadFonts(context);
    }
    return fonts[fontIdentifier];
}


private static void loadFonts(Context context) {
    for (int i = 0; i < NUM_OF_CUSTOM_FONTS; i++) {
        fonts[i] = Typeface.createFromAsset(context.getAssets(), fontPath[i]);
    }
    fontsLoaded = true;

}
}

This way, you can get the font from everywhere in your application.

We got the error:

GET http://localhost/pathToWebSite/somePage.aspx raised an http.status: 0 error

That call is made from windows task that calls a VBS file, so to troubleshoot the problem, pointed a browser to the url and we get a Privacy Error:

Your connection is not private

Attackers might be trying to steal your information from localhost (for example, passwords, messages, or credit cards). NET::ERR_CERT_COMMON_NAME_INVALID

Automatically report details of possible security incidents to Google. Privacy policy Back to safety This server could not prove that it is localhost; its security certificate is from *.ourdomain.com. This may be caused by a misconfiguration or an attacker intercepting your connection. Learn more.

This is because we have a IIS URL Rewrite rule set to force connections use https. That rule diverts http://localhost to https://localhost but our SSL certificate is based on an outside facing domain name not localhost, thus the error which is reported as status code 0. So a Privacy error could be a very obscure reason for this status code 0.

In our case the solution was to add an exception to the rule for localhost and allow http://localhost/pathToWebSite/somePage.aspx to use http. Obscure, yes, but I'll run into this next year and now I'll find my answer in a google search.

Another way to do this is to add the new characters to the string as follows:

Dim str As String

str = ""

To append text to your string this way:

str = str & "and this is more text"

Check this cool version out. The idea is to implement both String and ErrorType protocols and use the error's rawValue.

enum UserValidationError: String, Error {
  case noFirstNameProvided = "Please insert your first name."
  case noLastNameProvided = "Please insert your last name."
  case noAgeProvided = "Please insert your age."
  case noEmailProvided = "Please insert your email."
}

Usage:

do {
  try User.define(firstName,
                  lastName: lastName,
                  age: age,
                  email: email,
                  gender: gender,
                  location: location,
                  phone: phone)
}
catch let error as User.UserValidationError {
  print(error.rawValue)
  return
}

I had same problem and simple to resolve it.

Just uninstall git and re-install it.

#apt-get remove --purge git-svn git-core
#rm /usr/local/bin/git
#apt-get install git-svn git-core

and everything works well.

Hope this help.

You can search "slashdot effect analysis" for graphs of what you would see if some aspect of the site suddenly became popular in the news, e.g. this graph on wiki.

Web-applications that survive tend to be the ones which can generate static pages instead of putting every request through a processing language.

There was an excellent video (I think it might have been on ted.com? I think it might have been by flickr web team? Does someone know the link?) with ideas on how to scale websites beyond the single server, e.g. how to allocate connections amongst the mix of read-only and read-write servers to get best effect for various types of users.

Something like this:

firstList.AddRange (secondList);

Or, you can use the 'Union' extension method that is defined in System.Linq. With 'Union', you can also specify a comparer, which can be used to specify whether an item should be unioned or not.

Like this:

List<int> one = new List<int> { 1, 2, 3, 4, 5 };
List<int> second=new List<int> { 1, 2, 5, 6 };

var result = one.Union (second, new EqComparer ());

foreach( int x in result )
{
    Console.WriteLine (x);
}
Console.ReadLine ();

#region IEqualityComparer<int> Members
public class EqComparer : IEqualityComparer<int>
{
    public bool Equals( int x, int y )
    {
        return x == y;
    }

    public int GetHashCode( int obj )
    {
        return obj.GetHashCode ();
    }
}
#endregion

As an aside, it is always a good practice (and possibly a solution for this type of issue) to delete a large number of rows by using batches:

WHILE EXISTS (SELECT 1 
              FROM   YourTable 
              WHERE  <yourCondition>) 
  DELETE TOP(10000) FROM YourTable 
  WHERE  <yourCondition>

x = 0

    """

    global x 
    x += 1

def thread_task(): 
    """

    """
    for _ in range(100000):

    x = 0

    t1 = threading.Thread(target=thread_task) 
    t2 = threading.Thread(target=thread_task) 

    # start threads 
    t1.start() 
    t2.start() 

    # wait until threads finish their job 
    t1.join() 
    t2.join() 

if __name__ == "__main__": 
    for i in range(10): 
        main_task() 
        print("Iteration {0}: x = {1}".format(i,x))

// rename the .json file to .js and keep in src folder

Declare the json object as a variable

var customData = {
   "key":"value"
};

Export it using module.exports

module.exports = customData;

From the component that needs it, make sure to back out two folders deep

import customData from '../customData';

DB_CLOSE_DELAY=-1

hbm2ddl closes the connection after creating the table, so h2 discards it.

If you have your connection-url configured like this

jdbc:h2:mem:test

the content of the database is lost at the moment the last connection is closed.

If you want to keep your content you have to configure the url like this

jdbc:h2:mem:test;DB_CLOSE_DELAY=-1

If doing so, h2 will keep its content as long as the vm lives.

Notice the semicolon (;) rather than colon (:).

See the In-Memory Databases section of the Features page. To quote:

By default, closing the last connection to a database closes the database. For an in-memory database, this means the content is lost. To keep the database open, add ;DB_CLOSE_DELAY=-1 to the database URL. To keep the content of an in-memory database as long as the virtual machine is alive, use jdbc:h2:mem:test;DB_CLOSE_DELAY=-1.

I thought this would work, based on this source.

SELECT
  'Currently, ' 
  || (SELECT COUNT(*) FROM V$SESSION)
  || ' out of ' 
  || DECODE(VL.SESSIONS_MAX,0,'unlimited',VL.SESSIONS_MAX) 
  || ' connections are used.' AS USAGE_MESSAGE
FROM 
  V$LICENSE VL

However, Justin Cave is right. This query gives better results:

SELECT
  'Currently, ' 
  || (SELECT COUNT(*) FROM V$SESSION)
  || ' out of ' 
  || VP.VALUE 
  || ' connections are used.' AS USAGE_MESSAGE
FROM

   With fd

      .Title = "Please select the file."

      ' Clear out the current filters, and add our own.
      .Filters.Clear

      ' Show the dialog box. If the .Show method returns True, the

      If .Show = True Then

      End If
   End With
End Sub

I think this is what you are asking for.

Another case that could cause this error is

>>> np.ndindex(np.random.rand(60,60))
TypeError: only integer scalar arrays can be converted to a scalar index

Using the actual shape will fix it.

You don't need case in the where statement, just use parentheses and or:

Select * From Times
WHERE StartDate <= @Date AND EndDate >= @Date
AND (
    (@day = 'Monday' AND Monday = 1)
    OR (@day = 'Tuesday' AND Tuesday = 1)
    OR Wednesday = 1
)

Additionally, your syntax is wrong for a case. It doesn't append things to the string--it returns a single value. You'd want something like this, if you were actually going to use a case statement (which you shouldn't):

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date)
AND 1 = CASE WHEN @day = 'Monday' THEN Monday
             WHEN @day = 'Tuesday' THEN Tuesday
             ELSE Wednesday
        END 

And just for an extra umph, you can use the between operator for your date:

where @Date between StartDate and EndDate

Making your final query:

select
    * 
from 
    Times
where
    @Date between StartDate and EndDate
    and (
        (@day = 'Monday' and Monday = 1)
        or (@day = 'Tuesday' and Tuesday = 1)
        or Wednesday = 1
    )

It depends on your OS, but if you are on Windows XP, you need to go to Systems Properties, then Advanced, then Environment Variables, and include the php binary path to the %PATH% variable.

Locate it by browsing your WAMP directory. It's called php.exe

I write this function

def larger(x, than=0):
    if not x or min(x) > than:
        return True
    return False

Then

print larger([5, 6, 7], than=5)  # False
print larger([6, 7, 8], than=5)  # True
print larger([], than=5)  # True
print larger([6, 7, 8, None], than=5)  # False

Empty list on min() will raise ValueError. So I added if not x in condition.

For permanently delete your app follow below steps.

Step 1 :- GO to My Apps App in iTunes Connect

Here you can see your all app which are currently on Appstore.

Step 2 :- Select your app which you want to delete.(click on app-name)

Step 3 :- Select Pricing and Availability Tab.

Step 4 :- Select Remove from sale option.

Step 5 :- Click on save Button.

Now you will see below your app like , Developer Removed it from sale in Red Symbol in place of Green.

Step 6 :- Now again Select your app and Go to App information Tab. you will see Delete App option. (need to scroll bit bottom)

Step 7 :- After clicking on Delete button you will get warning like this ,

Step 8 :- Click on Delete button.

Congratulation , You have Permanently deleted your app successfully from appstore. Now , you cant able to see app on appstore aswellas in your developer account.

Note :-

When you have selected only Remove from sale option you have not deleted app permanently. You can able to make your app live again by clicking on Available in all territories option Again.

CREATE TABLE fractest( c1 TIME(3), c2 DATETIME(3), c3 TIMESTAMP(3) );

• copy the .war file in the webapps folder
• upload the file using the manager application - http://host:port/manager. You will have to setup some users beforehand.
• (not recommended, but working) - manually extract the .war file as a .zip archive and place the extracted files in webapps/webappname

Sometimes administrators configure tomcat so that war files are deployed outside the tomcat folder. Even in that case:

After you have it deployed (check the /logs dir for any problems), it should be accessible via: http://host:port/yourwebappname/. So in your case, one of those:

http://bilgin.ath.cx/TestWebApp/
http://bilgin.ath.cx:8080/TestWebApp/

If you don't manage by doing the above and googling - turn to your support. There might be an alternative port, or there might be something wrong with the application (and therefore in the logs)

Goran.it's answer does not work because of unicode problem in javascript - https://developer.mozilla.org/en-US/docs/Web/API/WindowBase64/Base64_encoding_and_decoding.

I ended up using the function given on Daniel Guerrero's blog: http://blog.danguer.com/2011/10/24/base64-binary-decoding-in-javascript/

Function is listed on github link: https://github.com/danguer/blog-examples/blob/master/js/base64-binary.js

Use these lines

var uintArray = Base64Binary.decode(base64_string);  
var byteArray = Base64Binary.decodeArrayBuffer(base64_string); 

Yes you can negate the test as SiegeX has already pointed out.

However you shouldn't use regular expressions for this - it can fail if your path contains special characters. Try this instead:

[[ ":$PATH:" != *":$1:"* ]]

(Source)

Just write <a href="#"></a>.

If that's what you want, you don't need a server-side control.

BYTE is nothing but typedef unsigned char BYTE;

You can easily use any of below constructors

string ( const char * s, size_t n );
string ( const char * s );

try fmod

The Print statement in TSQL is a misunderstood creature, probably because of its name. It actually sends a message to the error/message-handling mechanism that then transfers it to the calling application. PRINT is pretty dumb. You can only send 8000 characters (4000 unicode chars). You can send a literal string, a string variable (varchar or char) or a string expression. If you use RAISERROR, then you are limited to a string of just 2,044 characters. However, it is much easier to use it to send information to the calling application since it calls a formatting function similar to the old printf in the standard C library. RAISERROR can also specify an error number, a severity, and a state code in addition to the text message, and it can also be used to return user-defined messages created using the sp_addmessage system stored procedure. You can also force the messages to be logged.

Your error-handling routines won’t be any good for receiving messages, despite messages and errors being so similar. The technique varies, of course, according to the actual way you connect to the database (OLBC, OLEDB etc). In order to receive and deal with messages from the SQL Server Database Engine, when you’re using System.Data.SQLClient, you’ll need to create a SqlInfoMessageEventHandler delegate, identifying the method that handles the event, to listen for the InfoMessage event on the SqlConnection class. You’ll find that message-context information such as severity and state are passed as arguments to the callback, because from the system perspective, these messages are just like errors.

It is always a good idea to have a way of getting these messages in your application, even if you are just spooling to a file, because there is always going to be a use for them when you are trying to chase a really obscure problem. However, I can’t think I’d want the end users to ever see them unless you can reserve an informational level that displays stuff in the application.

Found this answer on a question listed as a duplicate. I find grep to be more admin-friendly than comm, so if you just want the set of matching lines (useful for comparing CSVs, for instance) simply use

grep -F -x -f file1 file2

or the simplified fgrep version

fgrep -xf file1 file2

Plus, you can use file2* to glob and look for lines in common with multiple files, rather than just two.

Some other handy variations include

• -n flag to show the line number of each matched line
• -c to only count the number of lines that match
• -v to display only the lines in file2 that differ (or use diff).

Using comm is faster, but that speed comes at the expense of having to sort your files first. It isn't very useful as a 'reverse diff'.

No, that's not how it is done. Normal way to initialize the base class is in the initialization list :

class A
{
public: 
    A(int val) {}
};

class B : public A
{
public:
  B( int v) : A( v )
  {
  }
};


void main()
{
    B b(10);
}

select tableA.id from tableA left outer join tableB on (tableA.id = tableB.id)
where tableB.id is null
order by tableA.id desc 

If your db knows how to do index intersections, this will only touch the primary key index

I think you can propagate the tap to the view controller and let it handle it. This is more acceptable approach. As for accessing a view controller from its view, you should maintain a reference to a view controller, since there is no another way. See this thread, it might help: Accessing view controller from a view

It's the same problem with managed and easy to use programming language as always - they are slow (and sometimes memory-eating).

These are languages to do control rather than processing. If I would have to write application to transform images and had to use Python too all the processing could be written in C++ and connected to Python via bindings while interface and process control would be definetely Python.

You can -Xours or -Xtheirs with git merge as well. So:

1. abort the current merge (for instance with git reset --hard HEAD)
2. merge using the strategy you prefer (git merge -Xours or git merge -Xtheirs)

DISCLAIMER: of course you can choose only one option, either -Xours or -Xtheirs, do use different strategy you should of course go file by file.

I do not know if there is a way for checkout, but I do not honestly think it is terribly useful: selecting the strategy with the checkout command is useful if you want different solutions for different files, otherwise just go for the merge strategy approach.

I think you can use methods of the str type to do this. There's no need for regular expressions:

def remove_prefix(text, prefix):
    if text.startswith(prefix): # only modify the text if it starts with the prefix
         text = text.replace(prefix, "", 1) # remove one instance of prefix
    return text

I started learning programming language with C++ and then Java and then Python and so this question bothered me a lot as well, until I understood the simple usage of each.

Class Method: Python unlike Java and C++ doesn't have constructor overloading. And so to achieve this you could use classmethod. Following example will explain this

Let's consider we have a Person class which takes two arguments first_name and last_name and creates the instance of Person.

class Person(object):

    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name

Now, if the requirement comes where you need to create a class using a single name only, just a first_name, you can't do something like this in Python.

This will give you an error when you will try to create an object (instance).

class Person(object):

    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name

    def __init__(self, first_name):
        self.first_name = first_name

However, you could achieve the same thing using @classmethod as mentioned below

class Person(object):

    def __init__(self, first_name, last_name):
        self.first_name = first_name
        self.last_name = last_name

    @classmethod
    def get_person(cls, first_name):
        return cls(first_name, "")

Static Method: This is rather simple, it's not bound to instance or class and you can simply call that using class name.

So let's say in above example you need a validation that first_name should not exceed 20 characters, you can simply do this.

@staticmethod  
def validate_name(name):
    return len(name) <= 20

and you could simply call using class name

Person.validate_name("Gaurang Shah")

There is a much easier way using the library http://svg.codeplex.com/ (Newer version @GIT, @NuGet). Here is my code

var byteArray = Encoding.ASCII.GetBytes(svgFileContents);
using (var stream = new MemoryStream(byteArray))
{
    var svgDocument = SvgDocument.Open(stream);
    var bitmap = svgDocument.Draw();
    bitmap.Save(path, ImageFormat.Png);
}

Codes in else statement block will be executed when the for loop was not be broke.

for x in xrange(1,5):
    if x == 5:
        print 'find 5'
        break
else:
    print 'can not find 5!'
#can not find 5!

From the docs: break and continue Statements, and else Clauses on Loops

Loop statements may have an else clause; it is executed when the loop terminates through exhaustion of the list (with for) or when the condition becomes false (with while), but not when the loop is terminated by a break statement. This is exemplified by the following loop, which searches for prime numbers:

>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print(n, 'equals', x, '*', n//x)
...             break
...     else:
...         # loop fell through without finding a factor
...         print(n, 'is a prime number')
...
2 is a prime number
3 is a prime number
4 equals 2 * 2
5 is a prime number
6 equals 2 * 3
7 is a prime number
8 equals 2 * 4
9 equals 3 * 3

(Yes, this is the correct code. Look closely: the else clause belongs to the for loop, not the if statement.)

When used with a loop, the else clause has more in common with the else clause of a try statement than it does that of if statements: a try statement’s else clause runs when no exception occurs, and a loop’s else clause runs when no break occurs. For more on the try statement and exceptions, see Handling Exceptions.

The continue statement, also borrowed from C, continues with the next iteration of the loop:

>>> for num in range(2, 10):
...     if num % 2 == 0:
...         print("Found an even number", num)
...         continue
...     print("Found a number", num)
Found an even number 2
Found a number 3
Found an even number 4
Found a number 5
Found an even number 6
Found a number 7
Found an even number 8
Found a number 9

Not sure what you meant, but you can permanently turn showing whitespaces on and off in Settings -> Editor -> General -> Appearance -> Show whitespaces.

Also, you can set it for a current file only in View -> Active Editor -> Show WhiteSpaces.

Edit:

Had some free time since it looks like a popular issue, I had written a plugin to inspect the code for such abnormalities. It is called Zero Width Characters locator and you're welcome to give it a try.

Try setting your num_threads inside your omp parallel code, it worked for me. This will give output as 4

#pragma omp parallel
{
   omp_set_num_threads(4);
   int id = omp_get_num_threads();
   #pragma omp for
   for (i = 0:n){foo(A);}
}

printf("Number of threads: %d", id);

Well, there is no shortcut to do it as per my findings, but somehow you
an achieve it in few simple steps

First you have to declare a bean of type 'ProtobufJsonFormatHttpMessageConverter'

@Bean  
@Primary  
public ProtobufJsonFormatHttpMessageConverter protobufHttpMessageConverter() {  
  return new ProtobufJsonFormatHttpMessageConverter(JsonFormat.parser(), JsonFormat.printer());  
}  

Then you can just write an Utility class like ResponseBuilder, because it can parse the request by default but without these changes it can not produce Json response. and then you can write few methods to convert the response types to its related object type.

public static <T> T build(Message message, Class<T> type) {
  Printer printer = JsonFormat.printer();
  Gson gson = new Gson();
  try {
    return gson.fromJson(printer.print(message), type);
  } catch (JsonSyntaxException | InvalidProtocolBufferException e) {
    throw new ApiException(HttpStatus.INTERNAL_SERVER_ERROR, "Response   conversion Error", e);
  }
}

Then you can call this method from your controller class as last line like -

return ResponseBuilder.build(<returned_service_object>, <Type>);

Hope this will help you to implement protobuf in json format.

Same thing, with jQuery:

$('#links a').each(function(){
    var me = $(this);
    me.html( me.text().replace(/(^\w+)/,'<strong>$1</strong>') );
  });

or

$('#links a').each(function(){
    var me = $(this)
       , t = me.text().split(' ');
    me.html( '<strong>'+t.shift()+'</strong> '+t.join(' ') );
  });

(Via 'Wizzud' on the jQuery Mailing List)

You can not add links from CSS, you will have to do so from the HTML code explicitly. For example, something like this:

<a href="whatever.html"><li id="header"></li></a>

A real edge case is where you have used an MySQL tool, (Sequel Pro in my case) to rename a database. Then created a database with the same name.

This kept foreign key constraints to the same database name, so the renamed database (e.g. my_db_renamed) had foreign key constraints in the newly created database (my_db)

Not sure if this is a bug in Sequel Pro, or if some use case requires this behaviour, but it cost me best part of a morning :/

I just ran into this issue while working with Eclipse. In my case, I had the correct Hadoop version downloaded (hadoop-2.5.0-cdh5.3.0.tgz), I extracted the contents and placed it directly in my C drive. Then I went to

Eclipse->Debug/Run Configurations -> Environment (tab) -> and added

variable: HADOOP_HOME

Value: C:\hadoop-2.5.0-cdh5.3.0

Change the file phpmyadmin.conf on c:/wamp64/alias/phpmyadmin.conf

php_admin_value upload_max_filesize 512M
php_admin_value post_max_size 512M
php_admin_value max_execution_time 360
php_admin_value max_input_time 360

It's very important you increase the time to 5000 or higher, Thus, the process will not stop when you are uploading a large file.

That works for me.

Stack views use intrinsic content size, so use layout constraints to define the dimensions of the views.

There is an easy way to add constraints quickly (example):

[view1.heightAnchor constraintEqualToConstant:100].active = true;

Complete Code:

- (void) setup {

    //View 1
    UIView *view1 = [[UIView alloc] init];
    view1.backgroundColor = [UIColor blueColor];
    [view1.heightAnchor constraintEqualToConstant:100].active = true;
    [view1.widthAnchor constraintEqualToConstant:120].active = true;


    //View 2
    UIView *view2 = [[UIView alloc] init];
    view2.backgroundColor = [UIColor greenColor];
    [view2.heightAnchor constraintEqualToConstant:100].active = true;
    [view2.widthAnchor constraintEqualToConstant:70].active = true;

    //View 3
    UIView *view3 = [[UIView alloc] init];
    view3.backgroundColor = [UIColor magentaColor];
    [view3.heightAnchor constraintEqualToConstant:100].active = true;
    [view3.widthAnchor constraintEqualToConstant:180].active = true;

    //Stack View
    UIStackView *stackView = [[UIStackView alloc] init];

    stackView.axis = UILayoutConstraintAxisVertical;
    stackView.distribution = UIStackViewDistributionEqualSpacing;
    stackView.alignment = UIStackViewAlignmentCenter;
    stackView.spacing = 30;


    [stackView addArrangedSubview:view1];
    [stackView addArrangedSubview:view2];
    [stackView addArrangedSubview:view3];

    stackView.translatesAutoresizingMaskIntoConstraints = false;
    [self.view addSubview:stackView];


    //Layout for Stack View
    [stackView.centerXAnchor constraintEqualToAnchor:self.view.centerXAnchor].active = true;
    [stackView.centerYAnchor constraintEqualToAnchor:self.view.centerYAnchor].active = true;
}

Note: This was tested on iOS 9

You don't give us the language, but if your regex flavour support look behind assertion, this is what you need:

.*(?<!a)$

(?<!a) is a negated lookbehind assertion that ensures, that before the end of the string (or row with m modifier), there is not the character "a".

See it here on Regexr

You can also easily extend this with other characters, since this checking for the string and isn't a character class.

.*(?<!ab)$

This would match anything that does not end with "ab", see it on Regexr

I think SELECT CAST( CAST([field] AS VARBINARY(120)) AS varchar(120)) for your update

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.

I'd recommend the DIY way which, combined with a good hashCode() and equals() method should be easy to proof in a unit test.

You'll want to use the specified market protocol:

final String appPackageName = "com.example"; // Can also use getPackageName(), as below
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));

Keep in mind, this will crash on any device that does not have the Market installed (the emulator, for example). Hence, I would suggest something like:

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}

While using getPackageName() from Context or subclass thereof for consistency (thanks @cprcrack!). You can find more on Market Intents here: link.

This happened with me when I copied a project code from one laptop to another one and tried running the project. What fixed this for me was:

1. Delete the project's build folder
2. Clean Project
3. Build project
4. Run

Below solution may help to someone.

I faced this issue, when I use implementation project(':my_project_other_modules') in the new module.

I discussed with my teammates and I finally I got the solution from one of the person, I have to use flavorDimensions & productFlavors. Because the app/build.gradle used flavorDimensions & productFlavors. When I add these in new module, the error didn't occur.

SELECT *

1. Generate a random number using your favourite random-number generator
2. Multiply and divide it to get a number matching the number of characters in your code alphabet
3. Get the item at that index in your code alphabet.
4. Repeat from 1) until you have the length you want

e.g (in pseudo code)

int myInt = random(0, numcharacters)
char[] codealphabet = 'ABCDEF12345'
char random = codealphabet[i]
repeat until long enough

As stated in the above answers, it's always a good practice to initialize the variables, but if you have something which you don't know what value should it takes, and you want to leave it uninitialized so you have to make sure that you are updating it before using it.

For example: Assume we have double _bmi; and you don't know what value should it takes, so you can leave it as it is, but before using it, you have to update its value first like calling a function that calculating BMI like follows:

String calculateBMI (){
_bmi = weight / pow( height/100, 2);
return _bmi.toStringAsFixed(1);}

or whatever, what I mean is, you can leave the variable as it is, but before using it make sure you have initialized it using whatever the method you are using.

Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.

That article contains the code for that:

Yeah Regex is cool, but there are other alternative.

• Select all the lines you want to prefix or suffix
• Goto menu Selection -> Split into Lines (Cmd/Ctrl + Shift + L)

This allows you to edit multiple lines at once. Now you can add *Quotes (") or anything * at start and end of each lines.

If you are working with a numerical array and need to re-index the array after removing empty elements, use the array_values function:

array_values(array_filter($array));

Also see: PHP reindex array?

public demo1() {
    initComponents();
    ImageIcon img = new ImageIcon("C:\\Users\\AMIT TIWARI\\Documents\\NetBeansProjects\\try\\src\\com\\dd.jpeg"); //full path of image
    Image img2 = img.getImage().getScaledInstance(mylabel.getWidth(), mylabel.getHeight(),1);
    ImageIcon img3 = new ImageIcon(img2);
    mylabel.setIcon(img3);
}

I have written this solution for another post who asked, how to calculate the difference between two dates, so I share what I have prepared:

// Here are the two dates to compare
var date1 = '2011-12-24';
var date2 = '2012-01-01';

// First we split the values to arrays date1[0] is the year, [1] the month and [2] the day
date1 = date1.split('-');
date2 = date2.split('-');

// Now we convert the array to a Date object, which has several helpful methods
date1 = new Date(date1[0], date1[1], date1[2]);
date2 = new Date(date2[0], date2[1], date2[2]);

// We use the getTime() method and get the unixtime (in milliseconds, but we want seconds, therefore we divide it through 1000)
date1_unixtime = parseInt(date1.getTime() / 1000);
date2_unixtime = parseInt(date2.getTime() / 1000);

// This is the calculated difference in seconds
var timeDifference = date2_unixtime - date1_unixtime;

// in Hours
var timeDifferenceInHours = timeDifference / 60 / 60;

// and finaly, in days :)
var timeDifferenceInDays = timeDifferenceInHours  / 24;

alert(timeDifferenceInDays);

You can skip some steps in the code, I have written it so to make it easy to understand.

You'll find a running example here: http://jsfiddle.net/matKX/

Add the column and update all rows in the DataTable, for example:

DataTable tbl = new DataTable();
tbl.Columns.Add(new DataColumn("ID", typeof(Int32)));
tbl.Columns.Add(new DataColumn("Name", typeof(string)));
for (Int32 i = 1; i <= 10; i++) {
    DataRow row = tbl.NewRow();
    row["ID"] = i;
    row["Name"] = i + ". row";
    tbl.Rows.Add(row);
}
DataColumn newCol = new DataColumn("NewColumn", typeof(string));
newCol.AllowDBNull = true;
tbl.Columns.Add(newCol);
foreach (DataRow row in tbl.Rows) {
    row["NewColumn"] = "You DropDownList value";
}
//if you don't want to allow null-values'
newCol.AllowDBNull = false;

1. I'm fortunate and my large data sets are saved by the instrument in "chunks" (subsets) of roughly 100 MB (32bit binary). Thus I can do pre-processing steps (deleting uninformative parts, downsampling) sequentially before fusing the data set.

2. Calling gc () "by hand" can help if the size of the data get close to available memory.

3. Sometimes a different algorithm needs much less memory.
   Sometimes there's a trade off between vectorization and memory use.
   compare: split & lapply vs. a for loop.

4. For the sake of fast & easy data analysis, I often work first with a small random subset (sample ()) of the data. Once the data analysis script/.Rnw is finished data analysis code and the complete data go to the calculation server for over night / over weekend / ... calculation.

Building on the answer by @Dion Truter and @Wade Williams, the following shell script will drop all tables, after first showing what it is about to run, and giving you a chance to abort using Ctrl-C.

#!/bin/bash

DB_HOST=xxx
DB_USERNAME=xxx
DB_PASSWORD=xxx
DB_NAME=xxx

CMD="mysql -sN -h ${DB_HOST} -u ${DB_USERNAME} -p${DB_PASSWORD} ${DB_NAME}"

# Generate the drop statements
TMPFILE=/tmp/drop-${RANDOM}.sql
echo 'SET FOREIGN_KEY_CHECKS = 0;' > ${TMPFILE}
${CMD} $@ >> ${TMPFILE} << ENDD
    SELECT concat('DROP TABLE IF EXISTS \`', table_name, '\`;')
    FROM information_schema.tables
    WHERE table_schema = '${DB_NAME}';
ENDD
echo 'SET FOREIGN_KEY_CHECKS = 1;' >> ${TMPFILE}

# Warn what we are about to do
echo
cat ${TMPFILE}
echo
echo "Press ENTER to proceed (or Ctrl-C to abort)."
read

# Run the SQL
echo "Dropping tables..."
${CMD} $@ < ${TMPFILE}
echo "Exit status is ${?}."
rm ${TMPFILE}

The simplest way is with the pkill command. In your case:

pkill -9 -t pts/6
pkill -9 -t pts/9
pkill -9 -t pts/10

Regarding tty sessions, the commands below are always useful:

w - shows active terminal sessions

tty - shows your current terminal session (so you won't close it by accident)

last | grep logged - shows currently logged users

Sometimes we want to close all sessions of an idle user (ie. when connections are lost abruptly).

pkill -u username - kills all sessions of 'username' user.

And sometimes when we want to kill all our own sessions except the current one, so I made a script for it. There are some cosmetics and some interactivity (to avoid accidental running on the script).

#!/bin/bash
MYUSER=`whoami`
MYSESSION=`tty | cut -d"/" -f3-`
OTHERSESSIONS=`w $MYUSER | grep "^$MYUSER" | grep -v "$MYSESSION" | cut -d" " -f2`
printf "\e[33mCurrent session\e[0m: $MYUSER[$MYSESSION]\n"

if [[ ! -z $OTHERSESSIONS ]]; then
  printf "\e[33mOther sessions:\e[0m\n"
  w $MYUSER | egrep "LOGIN@|^$MYUSER" | grep -v "$MYSESSION" | column -t
  echo ----------
  read -p "Do you want to force close all your other sessions? [Y]Yes/[N]No: " answer
  answer=`echo $answer | tr A-Z a-z`
  confirm=("y" "yes")

  if [[ "${confirm[@]}" =~ "$answer" ]]; then
  for SESSION in $OTHERSESSIONS
    do
         pkill -9 -t $SESSION
         echo Session $SESSION closed.
    done
  fi
else
        echo "There are no other sessions for the user '$MYUSER'".
fi

To easily check for problems with tabs/spaces you can actually do this:

python -m tabnanny yourfile.py

or you can just set up your editor correctly of course :-)

I dont think adding dual functions inside the toggle function works for a registered click event (Unless I'm missing something)

For example:

$('.btnName').click(function() {
 top.$('#panel').toggle(function() {
   $(this).animate({ 
     // style change
   }, 500);
   },
   function() {
   $(this).animate({ 
     // style change back
   }, 500);
 });

Another use for volatile is signal handlers. If you have code like this:

int quit = 0;
while (!quit)
{
    /* very small loop which is completely visible to the compiler */
}

The compiler is allowed to notice the loop body does not touch the quit variable and convert the loop to a while (true) loop. Even if the quit variable is set on the signal handler for SIGINT and SIGTERM; the compiler has no way to know that.

However, if the quit variable is declared volatile, the compiler is forced to load it every time, because it can be modified elsewhere. This is exactly what you want in this situation.

If you just want to calculate the schema size without tablespace free space and indexes :

select
   sum(bytes)/1024/1024 as size_in_mega,
   segment_type
from
   dba_segments
where
   owner='<schema's owner>'
group by
   segment_type;

For all schemas

select
   sum(bytes)/1024/1024 as size_in_mega, owner
from
   dba_segments
group by
  owner;

i solved with a max-width in my main css-file.

/* Set width on the form input elements since they're 100% wide by default */
input,
select,
textarea {
    max-width: 280px;
}

It's a simple solution with little "code"

Some people may find an async example useful:

var response = await fetch("https://httpbin.org/ip");
var body = await response.json(); // .json() is asynchronous and therefore must be awaited

json() converts the response's body from a ReadableStream to a json object.

The await statements must be wrapped in an async function, however you can run await statements directly in the console of Chrome (as of version 62).

Create a test utility method. Specially useful if you need it for more than once.

@Test
public void testMyTest() {
    // ...
    Foo<Bar> mockFooBar = mockFoo();
    when(mockFooBar.getValue).thenReturn(new Bar());

    Foo<Baz> mockFooBaz = mockFoo();
    when(mockFooBaz.getValue).thenReturn(new Baz());

    Foo<Qux> mockFooQux = mockFoo();
    when(mockFooQux.getValue).thenReturn(new Qux());
    // ...
}

@SuppressWarnings("unchecked") // still needed :( but just once :)
private <T> Foo<T> mockFoo() {
    return mock(Foo.class);
}

If you can edit the class containing that object, I usually just add the annotation

import com.fasterxml.jackson.annotation.JsonIgnore;

@JsonIgnore 
NonSerializeableClass obj;

HTML and XML entities are just a way of referencing a Unicode code-point in a way that reliably works regardless of the encoding of the actual page, making them useful for using esoteric Unicode characters in a page using 7-bit ASCII or some other encoding scheme, ideally on a one-off basis. They're also used to escape the <, >, " and & characters as these are reserved in SGML.

Anyway, Unicode has a number of tick/check characters, as per Wikipedia ( http://en.wikipedia.org/wiki/Tick_(check_mark) ).

Ideally you should save/store your HTML in a Unicode format like UTF-8 or 16, thus obviating the need to use HTML entities to represent a Unicode character. Nonetheless use: ✔ ✔.

All a [self.navigationController pushViewController:controller animated:YES]; does is animate a transition, and add it to the navigation controller stack, and some other cool navigation bar animation stuffs. If you don't care about the bar animation, then this code should work. The bar does appear on the new controller, and you get an interactive pop gesture!

//Make Controller
DetailViewController *controller = [[DetailViewController alloc] initWithNibName:nil                                                                                 
                                    bundle:[NSBundle mainBundle]];  
//Customize presentation
controller.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
controller.modalPresentationStyle = UIModalPresentationCurrentContext;

//Present controller
[self presentViewController:controller 
                   animated:YES 
                 completion:nil];
//Add to navigation Controller
[self navigationController].viewControllers = [[self navigationController].viewControllers arrayByAddingObject:controller];
//You can't just [[self navigationController].viewControllers addObject:controller] because viewControllers are for some reason not a mutable array.

Edit: Sorry, presentViewController will fill the full screen. You will need to make a custom transition, with CGAffineTransform.translation or something, animate the controller with the transition, then add it to the navigationController's viewControllers.

Try saving your .c file before building. I believe your computer is referencing a path to a file with no information inside of it.

--Had similar issue when building C projects

I had similar issue for android-29. My issue occurred because when AS was unzipping one downloaded SDK I had stopped it. For solving the issue disable gradle offline mode then sync with gradle files. You may need to set proxy and enable it.

I used:

 git reset --hard

I lost some changes, but this is ok.

It provides nothing else but a standardization of the data. The values it creates are known under several different names, one of them being z-scores ("Z" because the normal distribution is also known as the "Z distribution").

For using DOSBox with SDL, you will need to set or change the following:

[sdl]
windowresolution=1280x960
output=opengl

Here is three options to put those settings:

1. Edit user's default configuration, for example, using vi:

   $ dosbox -printconf
   /home/USERNAME/.dosbox/dosbox-0.74.conf
   $ vi "$(dosbox -printconf)"
   $ dosbox
   

2. For temporary resize, create a new configuration with the three lines above, say newsize.conf:

   $ dosbox -conf newsize.conf
   

   You can use -conf to load multiple configuration and/or with -userconf for default configuration, for example:

   $ dosbox -userconf -conf newsize.conf 
   [snip]
   ---
   CONFIG:Loading primary settings from config file /home/USERNAME/.dosbox/dosbox-0.74.conf
   CONFIG:Loading additional settings from config file newsize.conf
   [snip]
   

3. Create a dosbox.conf under current directory, DOSBox loads it as default.

DOSBox should start up and resize to 1280x960 in this case.

Note that you probably would not get any size you desired, for instance, I set 1280x720 and I got 1152x720.

From the structure of your source Object, I would try:

containerObject= new JSONObject(container);
 if(containerObject.has("LabelData")){
  JSONObject innerObject = containerObject.getJSONObject("LabelData");
     if(innerObject.has("video")){
        //Do with video
    }
}

Use smaller h

// 24 hrs 
H:i 
// output 14:20

// 12 hrs 
h:i 
// output 2:20

The solution in my case was to take any special characters out of the URL you're trying to access. I had a tilde (~) and a percentage symbol in there, and the $.get() call failed silently.

I think you are trying to run an emulator based on x86. I got the same error when I just download the HAXM under Extras category of Android SDK Manager. Actually, you need install it. Go to the directory of extras and run the installation of HAXM. Hope this will solve your problem.

Note that WebMvcConfigurerAdapter is deprecated now (see WebMvcConfigurerAdapter). Due to Java 8 default methods, you only have to implement WebMvcConfigurer.

For extending control functionality like this, I like to use extension methods so that it can be reused easily. Here is a starter extensions file that contains an extension to disable sorting on a datagridview.

To use it, just include it in your project and call like this

myDatagridView.DisableSorting()

In my case, I added this line of code in the DataBindingComplete eventhandler of the DataGridView where I wanted sorting disabled

Imports System.ComponentModel
Imports System.Reflection
Imports System.Runtime.CompilerServices
Imports System.Windows.Forms

Public Module Extensions

<Extension()>
Public Sub DisableSorting(datagrid As DataGridView)
    For index = 0 To datagrid.Columns.Count - 1
        datagrid.Columns(index).SortMode = DataGridViewColumnSortMode.NotSortable
    Next
End Sub


End Module

If you have something like this:

t.has_key(ew)

change it to below for running on Python 3.X and above:

key = ew
if key not in t

In case you actually mean what you seem to ask, I'll provide this alternative answer.

You say you want the dict to return a specified value, you do not say you want to set that value at the same time, like defaultdict does. This will do so:

class DictWithDefault(dict):
    def __init__(self, default, **kwargs):
        self.default = default
        super(DictWithDefault, self).__init__(**kwargs)

    def __getitem__(self, key):
        if key in self:
            return super(DictWithDefault, self).__getitem__(key)
        return self.default

Use like this:

d = DictWIthDefault(99, x=5, y=3)
print d["x"]   # 5
print d[42]    # 99
42 in d        # False
d[42] = 3
42 in d        # True

Alternatively, you can use a standard dict like this:

d = {3: 9, 4: 2}
default = 99
print d.get(3, default)  # 9
print d.get(42, default) # 99

This worked for me, no need to keep a lastSelected if you know the optionIndex to select.

var optionIndex = ...
$(this)[0].options[optionIndex].selected = true;

The simplest way I manage to solve the issue was is by using a ZStack + .edgesIgnoringSafeArea(.all)

struct TestView : View {

    var body: some View {
        ZStack() {
            Color.yellow.edgesIgnoringSafeArea(.all)
            VStack {
                Text("Hello World")
            }
        }
    }
}

Try this:

$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UCS-2BE');
}, $str);

In case it's UTF-16 based C/C++/Java/Json-style:

$str = preg_replace_callback('/\\\\u([0-9a-fA-F]{4})/', function ($match) {
    return mb_convert_encoding(pack('H*', $match[1]), 'UTF-8', 'UTF-16BE');
}, $str);

List<String> lst = new ArrayList<String>();

lst.add("Ram");
lst.add("Ram");
lst.add("Shiv");
lst.add("Boss");

Map<String, Integer> mp = new HashMap<String, Integer>();

for (String string : lst) {

    if(mp.keySet().contains(string))
    {
        mp.put(string, mp.get(string)+1);

    }else
    {
        mp.put(string, 1);
    }
}

System.out.println("=mp="+mp);

Output:

=mp= {Ram=2, Boss=1, Shiv=1}

I couldn't make any of the answers here to work. As a horrible hack, I store in local storage a timestamp when I change the route, and check at page initialization whether this timestamp is set and recent, in that case I don't trigger some initialization actions.

In controller:

window.localStorage['routeChangeWithoutReloadTimestamp'] = new Date().getTime();
$location.path(myURL);

In config:

.when(myURL, {
            templateUrl: 'main.html',
            controller:'MainCtrl',
            controllerAs: 'vm',
            reloadOnSearch: false,
            resolve:
            {
                var routeChangeWithoutReloadTimestamp =
                    window.localStorage['routeChangeWithoutReloadTimestamp'];
                var currentTimestamp = new Date().getTime();
                if (!routeChangeWithoutReloadTimestamp ||
                        currentTimestamp - routeChangeWithoutReloadTimestamp >= 5000) {
                    //initialization code here
                }
                //reset the timestamp to trigger initialization when needed
                window.localStorage['routeChangeWithoutReloadTimestamp'] = 0;
            }
});

I used a timestamp rather than a boolean, just in case the code is interrupted before having a chance to reinit the value stored before changing route. The risk of collision between tabs is very low.

A C compiler itself won't provide you with GUI functionality, but there are plenty of libraries for that sort of thing. The most popular is probably GTK+, but it may be a little too complicated if you are just starting out and want to quickly get a GUI up and running.

For something a little simpler, I would recommend IUP. With it, you can use a simple GUI definition language called LED to layout controls (but you can do it with pure C, if you want to).

Correct solution is to copy or install to /usr/local/bin not /usr/bin.This is due to System Integrity Protection (SIP). SIP makes /usr/bin read-only but leaves /usr/local as read-write.

SIP should not be disabled as stated in the answer above because it adds another layer of protection against malware gaining root access. Here is a complete explanation of what SIP does and why it is useful.

As suggested in this answer one should not disable SIP (rootless mode) "It is not recommended to disable rootless mode! The best practice is to install custom stuff to "/usr/local" only."

Solution 1: Framework blackboxing

Works great, minimal setup and no third parties.

According to Chrome's documentation:

What happens when you blackbox a script?

Exceptions thrown from library code will not pause (if Pause on exceptions is enabled), Stepping into/out/over bypasses the library code, Event listener breakpoints don't break in library code, The debugger will not pause on any breakpoints set in library code. The end result is you are debugging your application code instead of third party resources.

1. Pop open Chrome Developer Tools (F12 or ?+?+i), go to settings (upper right, or F1). Find a tab on the left called "Blackboxing"

2. This is where you put the RegEx pattern of the files you want Chrome to ignore while debugging. For example: jquery\..*\.js (glob pattern/human translation: jquery.*.js)
3. If you want to skip files with multiple patterns you can add them using the pipe character, |, like so: jquery\..*\.js|include\.postload\.js (which acts like an "or this pattern", so to speak. Or keep adding them with the "Add" button.
4. Now continue to Solution 3 described down below.

Bonus tip! I use Regex101 regularly (but there are many others: ) to quickly test my rusty regex patterns and find out where I'm wrong with the step-by-step regex debugger. If you are not yet "fluent" in Regular Expressions I recommend you start using sites that help you write and visualize them such as http://buildregex.com/ and https://www.debuggex.com/

You can also use the context menu when working in the Sources panel. When viewing a file, you can right-click in the editor and choose Blackbox Script. This will add the file to the list in the Settings panel:

Solution 2: Visual Event

It's an excellent tool to have:

Visual Event is an open-source Javascript bookmarklet which provides debugging information about events that have been attached to DOM elements. Visual Event shows:

• Which elements have events attached to them
• The type of events attached to an element
• The code that will be run with the event is triggered
• The source file and line number for where the attached function was defined (Webkit browsers and Opera only)

Solution 3: Debugging

You can pause the code when you click somewhere in the page, or when the DOM is modified... and other kinds of JS breakpoints that will be useful to know. You should apply blackboxing here to avoid a nightmare.

In this instance, I want to know what exactly goes on when I click the button.

1. Open Dev Tools -> Sources tab, and on the right find Event Listener Breakpoints:

   

2. Expand Mouse and select click

3. Now click the element (execution should pause), and you are now debugging the code. You can go through all code pressing F11 (which is Step in). Or go back a few jumps in the stack. There can be a ton of jumps

Solution 4: Fishing keywords

With Dev Tools activated, you can search the whole codebase (all code in all files) with ?+?+F or:

and searching #envio or whatever the tag/class/id you think starts the party and you may get somewhere faster than anticipated.

Be aware sometimes there's not only an img but lots of elements stacked, and you may not know which one triggers the code.

If this is a bit out of your knowledge, take a look at Chrome's tutorial on debugging.

Please check if postgres(or any other database service) is running properly.

Try to use this code to handle server disconnect:

var db_config = {
  host: 'localhost',
    user: 'root',
    password: '',
    database: 'example'
};

var connection;

function handleDisconnect() {
  connection = mysql.createConnection(db_config); // Recreate the connection, since
                                                  // the old one cannot be reused.

  connection.connect(function(err) {              // The server is either down
    if(err) {                                     // or restarting (takes a while sometimes).
      console.log('error when connecting to db:', err);
      setTimeout(handleDisconnect, 2000); // We introduce a delay before attempting to reconnect,
    }                                     // to avoid a hot loop, and to allow our node script to
  });                                     // process asynchronous requests in the meantime.
                                          // If you're also serving http, display a 503 error.
  connection.on('error', function(err) {
    console.log('db error', err);
    if(err.code === 'PROTOCOL_CONNECTION_LOST') { // Connection to the MySQL server is usually
      handleDisconnect();                         // lost due to either server restart, or a
    } else {                                      // connnection idle timeout (the wait_timeout
      throw err;                                  // server variable configures this)
    }
  });
}

handleDisconnect();

In your code i am missing the parts after connection = mysql.createConnection(db_config);

Event listeners

First off it's important to understand that there are two kinds of "event listeners":

1. Scope event listeners registered via $on:

   $scope.$on('anEvent', function (event, data) {
     ...
   });
   

2. Event handlers attached to elements via for example on or bind:

   element.on('click', function (event) {
     ...
   });
   

$scope.$destroy()

When $scope.$destroy() is executed it will remove all listeners registered via $on on that $scope.

It will not remove DOM elements or any attached event handlers of the second kind.

This means that calling $scope.$destroy() manually from example within a directive's link function will not remove a handler attached via for example element.on, nor the DOM element itself.

element.remove()

Note that remove is a jqLite method (or a jQuery method if jQuery is loaded before AngularjS) and is not available on a standard DOM Element Object.

When element.remove() is executed that element and all of its children will be removed from the DOM together will all event handlers attached via for example element.on.

It will not destroy the $scope associated with the element.

To make it more confusing there is also a jQuery event called $destroy. Sometimes when working with third-party jQuery libraries that remove elements, or if you remove them manually, you might need to perform clean up when that happens:

element.on('$destroy', function () {
  scope.$destroy();
});

What to do when a directive is "destroyed"

This depends on how the directive is "destroyed".

A normal case is that a directive is destroyed because ng-view changes the current view. When this happens the ng-view directive will destroy the associated $scope, sever all the references to its parent scope and call remove() on the element.

This means that if that view contains a directive with this in its link function when it's destroyed by ng-view:

scope.$on('anEvent', function () {
 ...
});

element.on('click', function () {
 ...
});

Both event listeners will be removed automatically.

However, it's important to note that the code inside these listeners can still cause memory leaks, for example if you have achieved the common JS memory leak pattern circular references.

Even in this normal case of a directive getting destroyed due to a view changing there are things you might need to manually clean up.

For example if you have registered a listener on $rootScope:

var unregisterFn = $rootScope.$on('anEvent', function () {});

scope.$on('$destroy', unregisterFn);

This is needed since $rootScope is never destroyed during the lifetime of the application.

The same goes if you are using another pub/sub implementation that doesn't automatically perform the necessary cleanup when the $scope is destroyed, or if your directive passes callbacks to services.

Another situation would be to cancel $interval/$timeout:

var promise = $interval(function () {}, 1000);

scope.$on('$destroy', function () {
  $interval.cancel(promise);
});

If your directive attaches event handlers to elements for example outside the current view, you need to manually clean those up as well:

var windowClick = function () {
   ...
};

angular.element(window).on('click', windowClick);

scope.$on('$destroy', function () {
  angular.element(window).off('click', windowClick);
});

These were some examples of what to do when directives are "destroyed" by Angular, for example by ng-view or ng-if.

If you have custom directives that manage the lifecycle of DOM elements etc. it will of course get more complex.

# Vendor
/vendor/braintree/braintree_php/*

I would suggest following two ways to implement this in Oracle.

1. Using Sub-query:

select distinct SALARY   
from EMPLOYEE e1  
where 1=(select count(DISTINCT e2.SALARY) from EMPLOYEE e2 where         
  e2.SALARY>e1.SALARY);

This is very simple query to get required output. However, this query is quite slow as each salary in inner query is compared with all distinct salaries.

2. Using DENSE_RANK():

select distinct SALARY   
from
  (
    select e1.*, DENSE_RANK () OVER (order by SALARY desc) as RN 
    from EMPLOYEE e
  ) E
 where E.RN=2;

This is very efficient query. It works well with DENSE_RANK() which assigns consecutive ranks unlike RANK() which assigns next rank depending on row number which is like olympic medaling.

Difference between RANK() and DENSE_RANK(): https://oracle-base.com/articles/misc/rank-dense-rank-first-last-analytic-functions

Null is a special object type like:

>>>type(None)
<class 'NoneType'>

You can check if an object is in class 'NoneType':

>>>variable = None
>>>variable is None
True

So lets say you have Activity AB that controls Frag A and Fragment B. Inside Fragment A you need an interface that Activity AB can implement. In the sample android code, they have:

private Callbacks mCallbacks = sDummyCallbacks;

/*A callback interface that all activities containing this fragment must implement. This mechanism allows activities to be notified of item selections. */

public interface Callbacks {
/*Callback for when an item has been selected. */    
      public void onItemSelected(String id);
}

/*A dummy implementation of the {@link Callbacks} interface that does nothing. Used only when this fragment is not attached to an activity. */    
private static Callbacks sDummyCallbacks = new Callbacks() {
    @Override
    public void onItemSelected(String id) {
    }
};

The Callback interface is put inside one of your Fragments (let’s say Fragment A). I think the purpose of this Callbacks interface is like a nested class inside Frag A which any Activity can implement. So if Fragment A was a TV, the CallBacks is the TV Remote (interface) that allows Fragment A to be used by Activity AB. I may be wrong about the detail because I'm a noob but I did get my program to work perfectly on all screen sizes and this is what I used.

So inside Fragment A, we have: (I took this from Android’s Sample programs)

@Override
public void onListItemClick(ListView listView, View view, int position, long id) {
super.onListItemClick(listView, view, position, id);
// Notify the active callbacks interface (the activity, if the
// fragment is attached to one) that an item has been selected.
mCallbacks.onItemSelected(DummyContent.ITEMS.get(position).id);
//mCallbacks.onItemSelected( PUT YOUR SHIT HERE. int, String, etc.);
//mCallbacks.onItemSelected (Object);
}

And inside Activity AB we override the onItemSelected method:

public class AB extends FragmentActivity implements ItemListFragment.Callbacks {
//...
@Override
//public void onItemSelected (CATCH YOUR SHIT HERE) {
//public void onItemSelected (Object obj) {
    public void onItemSelected(String id) {
    //Pass Data to Fragment B. For example:
    Bundle arguments = new Bundle();
    arguments.putString(“FragmentB_package”, id);
    FragmentB fragment = new FragmentB();
    fragment.setArguments(arguments);
    getSupportFragmentManager().beginTransaction().replace(R.id.item_detail_container, fragment).commit();
    }

So inside Activity AB, you basically throwing everything into a Bundle and passing it to B. If u are not sure how to use a Bundle, look the class up.

I am basically going by the sample code that Android provided. The one with the DummyContent stuff. When you make a new Android Application Package, it's the one titled MasterDetailFlow.

-- Disable the constraints on a table called tableName:
ALTER TABLE tableName NOCHECK CONSTRAINT ALL

-- Re-enable the constraints on a table called tableName:
ALTER TABLE tableName WITH CHECK CHECK CONSTRAINT ALL
---------------------------------------------------------

-- Disable constraints for all tables:
EXEC sp_msforeachtable 'ALTER TABLE ? NOCHECK CONSTRAINT all'

-- Re-enable constraints for all tables:
EXEC sp_msforeachtable 'ALTER TABLE ? WITH CHECK CHECK CONSTRAINT all'
---------------------------------------------------------

You could try calling toString() on the prepared statement after you've set the bind values.

PreparedStatement query = connection.prepareStatement(aSQLStatement);
System.out.println("Before : " + query.toString());
query.setString(1, "Hello");
query.setString(2, "World");
System.out.println("After : " + query.toString());

This works when you use the JDBC MySQL driver, but I'm not sure if it will in other cases. You may have to keep track of all the bindings you make and then print those out.

Sample output from above code.

Before : com.mysql.jdbc.JDBC4PreparedStatement@fa9cf: SELECT * FROM test WHERE blah1=** NOT SPECIFIED ** and blah2=** NOT SPECIFIED **
After : com.mysql.jdbc.JDBC4PreparedStatement@fa9cf: SELECT * FROM test WHERE blah1='Hello' and blah2='World'

By using jquery function .closest(element) and .find(...).

Getting the parent element and looking for the child.

Finally, do the function needed.

$("#form").closest('form').find("input[type=text], textarea").val("");

Another way (credit):

@For /F "tokens=2,3,4 delims=/ " %%A in ('Date /t') do @( 
    Set Month=%%A
    Set Day=%%B
    Set Year=%%C
)

@echo DAY = %Day%
@echo Month = %Month%
@echo Year = %Year%

Note that both my answers here are still reliant on the order of the day and month as determined by regional settings - not sure how to work around that.

It's possible using the button element.

<button name="name" value="value" type="submit">Sök</button>

From the W3C page on button:

Buttons created with the BUTTON element function just like buttons created with the INPUT element, but they offer richer rendering possibilities: the BUTTON element may have content.

I agree with some of the others' answers. The <head> and <header> tags have two unique and very unrelated functions. The <header> tag, if I'm not mistaken, was introduced in HTML5 and was created for increased accessibility, namely for screen readers. It's generally used to indicate the heading of your document and, in order to work appropriately and effectively, should be placed inside the <body> tag. The <head> tag, since it's origin, is used for SEO in that it constructs all of the necessary meta data and such. A valid HTML structure for your page with both tags included would be like something like this:

<!DOCTYPE html/>
<html lang="es">
    <head>
        <!--crazy meta stuff here-->
    </head>
    <body>
        <header>
            <!--Optional nav tag-->
            <nav>
            </nav>
        </header>
        <!--Body content-->
    </body>
</html>

There is a current bug in glibc on Ubuntu which can have this effect: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1674733

To resolve it, update libc and all related (Packages that will be upgraded: libc-bin libc-dev-bin libc6 libc6-dev libfreetype6 libfreetype6-dev locales multiarch-support) and restart the server.

A while ago i wrote a detailed article about Hibernate key generators: http://blog.eyallupu.com/2011/01/hibernatejpa-identity-generators.html

Choosing the correct generator is a complicated task but it is important to try and get it right as soon as possible - a late migration might be a nightmare.

A little off topic but a good chance to raise a point usually overlooked which is sharing keys between applications (via API). Personally I always prefer surrogate keys and if I need to communicate my objects with other systems I don't expose my key (even though it is a surrogate one) – I use an additional ‘external key’. As a consultant I have seen more than once 'great' system integrations using object keys (the 'it is there let's just use it' approach) just to find a year or two later that one side has issues with the key range or something of the kind requiring a deep migration on the system exposing its internal keys. Exposing your key means exposing a fundamental aspect of your code to external constrains shouldn’t really be exposed to.

It's the destructor. This method is called when the instance of your class is destroyed:

Stack<int> *stack= new Stack<int>;
//do something
delete stack; //<- destructor is called here;

• Here's a page describing the differences (basically you can put html into a <button></button>)
• And another page describing why people avoid <button></button> (Hint: IE6)

Another IE problem when using <button />:

And while we're talking about IE, it's got a couple of bugs related to the width of buttons. It'll mysteriously add extra padding when you're trying to add styles, meaning you have to add a tiny hack to get things under control.

normaly is better image store in public folder (because it has write permission already that you can use when I upload images to it)

public
    upload_media
         photos
            image.png


$image  = public_path() . '/upload_media/photos/image.png'; // destination path

view PHP

<img src="<?= $image ?>">

View blade

<img src="{{ $image }}">

Unfortunately you're probably done with the animation and presentation already. In the hopes this answer can help future questioners, however, this blog post has a walkthrough of steps that can loop a single slide as a sort of sub-presentation.

First, click Slide Show > Set Up Show.

Put a checkmark to Loop continuously until 'Esc'.

Click Ok. Now, Click Slide Show > Custom Shows. Click New.

Select the slide you are looping, click Add. Click Ok and Close.

Click on the slide you are looping. Click Slide Show > Slide Transition. Under Advance slide, put a checkmark to Automatically After. This will allow the slide to loop automatically. Do NOT Apply to all slides.

Right click on the thumbnail of the current slide, select Hide Slide.

Now, you will need to insert a new slide just before the slide you are looping. On the new slide, insert an action button. Set the hyperlink to the custom show you have created. Put a checkmark on "Show and Return"

This has worked for me.

ES6 Update - ES6 (ES2015 specification) allows for default parameters

The following will work just fine in an ES6 (ES015) environment...

}

In general Android OS leverages a “theme” to allow app developers to globally apply a universal set of UI element styling parameters to Android applications as a whole, or, alternatively, to a single Activity subclass.

So there are three mainstream Android OS “system themes,” which you can specify in your Android Manifest XML file when you are developing apps for Version 3.0 and later versions

I am referring the (APPCOMPAT)support library here:-- So the three themes are 1. AppCompat Light Theme (Theme.AppCompat.Light)

2. AppCompat Dark Theme(Theme.AppCompat),

3. And a hybrid between these two ,AppCompat Light Theme with the Darker ActionBar.( Theme.AppCompat.Light.DarkActionBar)

AndroidManifest.xml and see the tag, the android theme is mentioned as:-- android:theme="@style/AppTheme"

Open the Styles.xml and we have base application theme declared there:--

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
  </style>

We need to override these parent theme elements to style the action bar.

ActionBar with different color background:--

To do this we need to create a new style MyActionBar(you can give any name) with a parent reference to @style/Widget.AppCompat.Light.ActionBar.Solid.Inverse that holds the style characteristics for the Android ActionBar UI element. So definition would be

<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="background">@color/red</item>
</style>

And this definition we need to reference in our AppTheme, pointing to overridden ActionBar styling as--

@style/MyActionBar

Change the title bar text color (e.g black to white):--

Now to change the title text color, we need to override the parent reference parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">

So the style definition would be

<style name="MyActionBarTitle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
    <item name="android:textColor">@color/white</item>
</style>

We’ll reference this style definition inside the MyActionBar style definition, since the TitleTextStyle modification is a child element of an ActionBar parent OS UI element. So the final definition of MyActionBar style element will be

<style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
    <item name="background">@color/red</item>
    <item name="titleTextStyle">@style/MyActionBarTitle</item>
</style>

SO this is the final Styles.xml

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme" parent="Theme.AppCompat.Light">
        <!-- This is the styling for action bar -->
        <item name="actionBarStyle">@style/MyActionBar</item>
    </style>

    <style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar.Solid.Inverse">
        <item name="background">@color/red</item>
        <item name="titleTextStyle">@style/MyActionBarTitle</item>
    </style>

    <style name="MyActionBarTitle" parent="@style/TextAppearance.AppCompat.Widget.ActionBar.Title">
        <item name="android:textColor">@color/white</item>
    </style>
</resources>

A blanket "no you shouldn't" is terrible advice. This is perfectly reasonable in many situations depending on your use case, workload, data entropy, hardware, etc.. What you shouldn't do is make assumptions.

It should be noted that you can specify a prefix which will limit MySQL's indexing, thereby giving you some help in narrowing down the results before scanning the rest. This may, however, become less useful over time as your prefix "fills up" and becomes less unique.

It's very simple to do, e.g.:

CREATE TABLE IF NOT EXISTS `foo` (
  `id` varchar(128),
  PRIMARY KEY (`id`(4))
)

Also note that the prefix (4) appears after the column quotes. Where the 4 means that it should use the first 4 characters of the 128 possible characters that can exist as the id.

Lastly, you should read how index prefixes work and their limitations before using them: https://dev.mysql.com/doc/refman/8.0/en/create-index.html

M.Ali's answer could be modified as

select Cast(Cast((37.0/38.0)*100 as decimal(18,2)) as varchar(5)) + ' %' as Percentage

it's easy to use:

frame.setResizable(false);

Quassnoi's answer works, but kind of leaves you on the hook for cleaning up the dates if they are dates in the middle of the day (his start of week leaves you one day earlier than you need to be if you use a time in the middle of the day -- you can test using GETDATE()).

I've used something like this in the past:

SELECT 
   CONVERT(varchar(50), (DATEADD(dd, @@DATEFIRST - DATEPART(dw, DATECOL), DATECOL)), 101),
   CONVERT(varchar(50), (DATEADD(dd, @@DATEFIRST - DATEPART(dw, DATECOL) - 6, DATECOL)), 101)

A side benefit of this is that by using @@DATEFIRST you can handle nonstandard week starting days (the default is Sunday, but with SET @@DATEFIRST you can change this).

It seems crazy that simple date manipulation in SQL Server has to be this arcane, but there you go...

or

public String getFileStream(final String inputFile) {
        String result = "";
        Scanner s = null;

        try {
            s = new Scanner(new BufferedReader(new FileReader(inputFile)));
            while (s.hasNext()) {
                result = result + s.nextLine();
            }
        } catch (final IOException ex) {
            ex.printStackTrace();
        } finally {
            if (s != null) {
                s.close();
            }
        }
        return result;
}

This gets first line as well.

You can simply truncate the table to reset the sequence

TRUNCATE TABLE TABLE_NAME

On Ubuntu, instead of using sh scriptname.sh to run the file, I've used . scriptname.sh and it worked! The first line of my file contains: #!/bin/bash

use this command to run the script

.name_of_script.sh

ord() will not work because your end string is two characters long.

Returns the ASCII value of the first character of string.

Watch it break.

From my testing, you need to check that the end string doesn't get "stepped over". The perl-style character incrementation is a cool method, but it is a single-stepping method. For this reason, an inner loop helps it along when necessary. This is actually not a bother, in fact, it is useful because we need to check if the loop(s) should be broken on each single step.

Code: (Demo)

function excelCols($letter,$end,$step=1){  // function doesn't check that $end is "later" than $letter
    if($step==0)return [];  // prevent infinite loop
    do{
        $letters[]=$letter;  // store letter
        for($x=0; $x<$step; ++$x){  // increment in accordance with $step declaration
            if($letter===$end)break(2);  // break if end is "stepped on"
            ++$letter;
        }
    }while(true);
    return $letters;    
}
echo implode(' ',excelCols('A','JJ',4));
echo "\n --- \n";
echo implode(' ',excelCols('A','BB',3));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',1));
echo "\n --- \n";
echo implode(' ',excelCols('A','ZZ',3));

Here is an array-functions approach:

Code: (Demo)

$start='C';
$end='DD';
$step=4;

// generate and store more than we need (this is an obvious method disadvantage)
$result=$array=range('A','Z',1);  // store A - Z as $array and $result
foreach($array as $a){
    foreach($array as $b){
        $result[]="$a$b";  // store double letter combinations
        if(in_array($end,$result)){break(2);}  // stop asap
    }
}
//echo implode(' ',$result),"\n\n";

// slice away from the front of the array
$result=array_slice($result,array_search($start,$result));  // reindex keys
//echo implode(' ',$result),"\n\n";

 // punch out elements that are not "stepped on"
$result=array_filter($result,function($k)use($step){return $k%$step==0;},ARRAY_FILTER_USE_KEY); // use modulo

// result is ready
echo implode(' ',$result);

Output:

First check whether the file exists in SDCard. If the file doesnot exists in SDcard then you can set image using setImageResource() methodand passing default image from drawable folder

Sample Code

File imageFile = new File(absolutepathOfImage);//absolutepathOfImage is absolute path of image including its name
        if(!imageFile.exists()){//file doesnot exist in SDCard

        imageview.setImageResource(R.drawable.defaultImage);//set default image from drawable folder
        }

What to do if :foo in its natural form contains slashes? You wouldn't want it to Isn't that the distinction the recommendation is attempting to preserve? It specifically notes,

The similarity to unix and other disk operating system filename conventions should be taken as purely coincidental, and should not be taken to indicate that URIs should be interpreted as file names.

If one was building an online interface to a backup program, and wished to express the path as a part of the URL path, it would make sense to encode the slashes in the file path, as that is not really part of the hierarchy of the resource - and more importantly, the route. /backups/2016-07-28content//home/dan/ loses the root of the filesystem in the double slash. Escaping the slashes is the appropriate way to distinguish, as I read it.

simple:

today="$(date '+%Y-%m-%d')"
yesterday="$(date -d yesterday '+%Y-%m-%d')"

As of now (studio 0.61) maintaining proper project structure is enough. No need to create separate test project as in eclipse (see below).

When compiling with -std=c++11, one can simply

  const char *s  = u8"\u0444";
  cout << s << endl;

You can also read up on the ILIKE keyword. It can be quite useful at times, albeit it does not conform to the SQL standard. See here for more information: http://www.postgresql.org/docs/9.2/static/functions-matching.html

Assuming you mean "list" where you say "array", you can do

if item in my_list:
    # whatever

This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.

1)From OS level(UNIX):-

dataserver -v

2)From Syabse isql:-

select @@version
go

sp_version
go

The calculation occurs immediately since the calculation call is bound in the template, which displays its result when quantity changes.

Instead you could try the following approach. Change your markup to the following:

<div ng-controller="myAppController" style="text-align:center">
  <p style="font-size:28px;">Enter Quantity:
      <input type="text" ng-model="quantity"/>
  </p>
  <button ng-click="calculateQuantity()">Calculate</button>
  <h2>Total Cost: Rs.{{quantityResult}}</h2>
</div>

Next, update your controller:

myAppModule.controller('myAppController', function($scope,calculateService) {
  $scope.quantity=1;
  $scope.quantityResult = 0;

  $scope.calculateQuantity = function() {
    $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  };
});

Here's a JSBin example that demonstrates the above approach.

The problem with this approach is the calculated result remains visible with the old value till the button is clicked. To address this, you could hide the result whenever the quantity changes.

This would involve updating the template to add an ng-change on the input, and an ng-if on the result:

<input type="text" ng-change="hideQuantityResult()" ng-model="quantity"/>

and

<h2 ng-if="showQuantityResult">Total Cost: Rs.{{quantityResult}}</h2>

In the controller add:

$scope.showQuantityResult = false;

$scope.calculateQuantity = function() {
  $scope.quantityResult = calculateService.calculate($scope.quantity, 10);
  $scope.showQuantityResult = true;
};

$scope.hideQuantityResult = function() {
  $scope.showQuantityResult = false;
}; 

These updates can be seen in this JSBin demo.

As the documentation states, 'replace' determines whether the current element is replaced by the directive. The other option is whether it is just added to as a child basically. If you look at the source of your plnkr, notice that for the second directive where replace is false that the div tag is still there. For the first directive it is not.

First result:

<span myd1="">directive template1</span>

Second result:

<div myd2=""><span>directive template2</span></div>

In windows, you need to use double quotes "". So the command would be

git commit -m "t"

With very large JavaScript applications, programmers are using more encapsulation of code to avoid polluting the global scope. And to make a function available to the onClick action in an HTML element, it has to be in the global scope.

You may have seen JS files that look like this...

(function(){
    ...[some code]
}());

These are Immediately Invoked Function Expressions (IIFEs) and any function declared within them will only exist within their internal scope.

If you declare function doSomething(){} within an IIFE, then make doSomething() an element's onClick action in your HTML page, you'll get an error.

If, on the other hand, you create an eventListener for that element within that IIFE and call doSomething() when the listener detects a click event, you're good because the listener and doSomething() share the IIFE's scope.

For little web apps with a minimal amount of code, it doesn't matter. But if you aspire to write large, maintainable codebases, onclick="" is a habit that you should work to avoid.

this worked for me /properties/maven uncheck resolve dependencies from Workspace projects.

public class palin

    static boolean isPalin(String s, int i, int j)
    {
        boolean b=true;
        if(s.charAt(i)==s.charAt(j))
        {
            if(i<=j)
                isPalin(s,(i+1),(j-1));
        }
        else
        {
            b=false;

        return b;
    }

    {
        String s1="madam";
        if(isPalin(s1, 0, s1.length()-1)==true)
            System.out.println(s1+" is palindrome");
        else
            System.out.println(s1+" is not palindrome");
    }
}

Make UIImageView and UILabel, and set image and text to both of this....then Place a custom button over imageView and Label....

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"search.png"]];
    imageView.frame = CGRectMake(x, y, imageView.frame.size.width, imageView.frame.size.height);
    [self.view addSubview:imageView];

UILabel *yourLabel = [[UILabel alloc] initWithFrame:CGRectMake(x, y,a,b)];
yourLabel.text = @"raj";
[self.view addSubview:yourLabel];

UIButton * yourBtn=[UIButton buttonWithType:UIButtonTypeCustom];
[yourBtn setFrame:CGRectMake(x, y,c,d)];
[yourBtn addTarget:self action:@selector(@"Your Action") forControlEvents:UIControlEventTouchUpInside];
[self.view addSubview:yourBtn];  

Try this :

public String ConvertMessage(String content_sendout){

        //use unicode (004E00650077) need to change to hex (&#x004E&#x;0065&#x;0077;) first ;
        String resultcontent_sendout = "";
        int i = 4;
        int lengthwelcomemsg = content_sendout.length()/i;
        for(int nadd=0;nadd<lengthwelcomemsg;nadd++){
            if(nadd == 0){
                resultcontent_sendout = "&#x"+content_sendout.substring(nadd*i, (nadd*i)+i) + ";&#x";
            }else if(nadd == lengthwelcomemsg-1){
                resultcontent_sendout += content_sendout.substring(nadd*i, (nadd*i)+i) + ";";
            }else{
                resultcontent_sendout += content_sendout.substring(nadd*i, (nadd*i)+i) + ";&#x";
            }
        }
        return resultcontent_sendout;
    }

The problem is that your PATH does not include the location of the node executable.

You can likely run node as "/usr/local/bin/node".

You can add that location to your path by running the following command to add a single line to your bashrc file:

echo 'export PATH=$PATH:/usr/local/bin' >> $HOME/.bashrc

echo 1 2 3 4 5| awk '{ for (i=3; i<=NF; i++) print $i }'

You can do it using namespaces, like this:

export namespace Library {
    export const BOOK_SHELF_NONE: string = 'NONE';
}

Then you can import it from anywhere else:

import {Library} from './Library';
console.log(Library.BOOK_SHELF_NONE);

If you need a class there as well include it inside the namespace: export class Book {...}

Another alternative:

Use the code from the unicodecsv package ...

https://pypi.python.org/pypi/unicodecsv/

>>> import unicodecsv as csv
>>> from io import BytesIO
>>> f = BytesIO()
>>> w = csv.writer(f, encoding='utf-8')
>>> _ = w.writerow((u'é', u'ñ'))
>>> _ = f.seek(0)
>>> r = csv.reader(f, encoding='utf-8')
>>> next(r) == [u'é', u'ñ']
True

This module is API compatible with the STDLIB csv module.

This is the cleanest approach

let dat = new Date() _x000D_
let copyOf = new Date(dat.valueOf())_x000D_
_x000D_
console.log(dat);_x000D_
console.log(copyOf);

Inheritance between two classes, where one class extends another class establishes "IS A" relationship.

Composition on the other end contains an instance of another class in your class establishes "Has A" relationship. Composition in java is is useful since it technically facilitates multiple inheritance.

For us VBers:

TrimEnd(New Char() {ControlChars.Cr, ControlChars.Lf})

Note that link could be different and it contains expiration timestamp, in this case 1592099895 (about 6 hours).

Now that you have the HLS playlist, you can open this URL in VLC and save it using "Record", or write a small ffmpeg command:

ffmpeg -i \

Swift version

A delegate is just a class that does some work for another class. Read the following code for a somewhat silly (but hopefully enlightening) Playground example that shows how this is done in Swift.

// A protocol is just a list of methods (and/or properties) that must
// be used by any class that adopts the protocol.
protocol OlderSiblingDelegate: class {
    // This protocol only defines one required method
    func getYourNiceOlderSiblingAGlassOfWater() -> String
}

class BossyBigBrother {
    
    // The delegate is the BossyBigBrother's slave. This position can 
    // be assigned later to whoever is available (and conforms to the 
    // protocol).
    weak var delegate: OlderSiblingDelegate?
    
    func tellSomebodyToGetMeSomeWater() -> String? {
        // The delegate is optional because there might not be anyone
        // nearby to boss around.
        return delegate?.getYourNiceOlderSiblingAGlassOfWater()
    }
}

// PoorLittleSister conforms to the OlderSiblingDelegate protocol
class PoorLittleSister: OlderSiblingDelegate {

    // This method is repquired by the protocol, but the protocol said
    // nothing about how it needs to be implemented.
    func getYourNiceOlderSiblingAGlassOfWater() -> String {
        return "Go get it yourself!"
    }
    
}

// initialize the classes
let bigBro = BossyBigBrother()
let lilSis = PoorLittleSister()

// Set the delegate 
// bigBro could boss around anyone who conforms to the 
// OlderSiblingDelegate protocol, but since lilSis is here, 
// she is the unlucky choice.
bigBro.delegate = lilSis

// Because the delegate is set, there is a class to do bigBro's work for him.
// bigBro tells lilSis to get him some water.
if let replyFromLilSis = bigBro.tellSomebodyToGetMeSomeWater() {
    print(replyFromLilSis) // "Go get it yourself!"
}

In actual practice, delegates are often used in the following situations

1. When a class needs to communicate some information to another class
2. When a class wants to allow another class to customize it

The classes don't need to know anything about each other beforehand except that the delegate class conforms to the required protocol.

I highly recommend reading the following two articles. They helped me understand delegates even better than the documentation did.

• What is Delegation? – A Swift Developer’s Guide
• How Delegation Works – A Swift Developer’s Guide

Using this RegExp seems works for IE 10 and IE 11:

function isIE(){
    return /Trident\/|MSIE/.test(window.navigator.userAgent);
}

I do not have a IE older than IE 10 to test this.

As an alternative to BalusC answer as it has been deprecated and you have to use proxies, you can use this package. Code sample:

Map<String, String> parameter = new HashMap<>();
parameter.put("q", "Coffee");
parameter.put("location", "Portland");
GoogleSearchResults serp = new GoogleSearchResults(parameter);

JsonObject data = serp.getJson();
JsonArray results = (JsonArray) data.get("organic_results");
JsonObject first_result = results.get(0).getAsJsonObject();
System.out.println("first coffee: " + first_result.get("title").getAsString());

Library on GitHub

h5py provides a model of datasets and groups. The former is basically arrays and the latter you can think of as directories. Each is named. You should look at the documentation for the API and examples:

http://docs.h5py.org/en/latest/quick.html

A simple example where you are creating all of the data upfront and just want to save it to an hdf5 file would look something like:

In [1]: import numpy as np
In [2]: import h5py
In [3]: a = np.random.random(size=(100,20))
In [4]: h5f = h5py.File('data.h5', 'w')
In [5]: h5f.create_dataset('dataset_1', data=a)
Out[5]: <HDF5 dataset "dataset_1": shape (100, 20), type "<f8">

In [6]: h5f.close()

You can then load that data back in using: '

In [10]: h5f = h5py.File('data.h5','r')
In [11]: b = h5f['dataset_1'][:]
In [12]: h5f.close()

In [13]: np.allclose(a,b)
Out[13]: True

Definitely check out the docs:

http://docs.h5py.org

Writing to hdf5 file depends either on h5py or pytables (each has a different python API that sits on top of the hdf5 file specification). You should also take a look at other simple binary formats provided by numpy natively such as np.save, np.savez etc:

http://docs.scipy.org/doc/numpy/reference/routines.io.html

In window form c#. If you use Enter event it will not work. try to use MouseUp event

    bool FlagEntered;
    private void textBox1_MouseUp(object sender, MouseEventArgs e)
    {
        if ((sender as TextBox).SelectedText == "" && !FlagEntered)
        {
            (sender as TextBox).SelectAll();
            FlagEntered = true;
        }
    }

    private void textBox1_Leave(object sender, EventArgs e)
    {
        FlagEntered = false;
    }

If you are using functional components in React

const [cars, setCars] = useState([{
  name: 'Audi',
  type: 'sedan'
}, {
  name: 'BMW',
  type: 'sedan'
}])

...

const newCar = {
  name: 'Benz',
  type: 'sedan'
}

const updatedCarsArray = [...cars, newCar];

setCars(updatedCarsArray);

U wrote an unnecessary div, just leave it like this

<div id="texts" style="white-space:nowrap;">
     <img src="tree.png"  align="left"/>
     A very long text(about 300 words) 
</div>

What u are looking for is white-space:nowrap; this code will do the trick.

import java.util.*;
public class SecondLargestNew
{
    public static void main(String args[])
    {
        int[] array = {0,12,74,26,82,3,89,8,94,3};  

    int highest = Integer.MIN_VALUE;
    int secondHighest = Integer.MIN_VALUE;


    for (int i = 0; i < array.length; i++) 
    {
        if (array[i] > highest) 
        {
            // ...shift the current highest number to second highest
            secondHighest = highest;
            // ...and set the new highest.
            highest = array[i];
        } else if (array[i] > secondHighest)
            {
            // Just replace the second highest
            secondHighest = array[i];
            }
    }
    System.out.println("second largest is "+secondHighest );
    System.out.println("largest is "+ highest);
        }
}

You may also need to override UIViewController disablesAutomaticKeyboardDismissal to get this to work in some cases. This may have to be done on the UINavigationController if you have one.

You can use the simple soupparser from lxml

Example:

from lxml.html.soupparser import fromstring

tree = fromstring("<a>Find me!</a>")
print tree.xpath("//a/text()")

Set the colspan attribute to 2.

...but please don't use tables for layout.

It is always good to implement exception handling. It does not only help to avoid unexpected exit of script but can also help to log errors and info notification. When using Python requests I prefer to catch exceptions like this:

    try:
        res = requests.get(adress,timeout=30)
    except requests.ConnectionError as e:
        print("OOPS!! Connection Error. Make sure you are connected to Internet. Technical Details given below.\n")
        print(str(e))            
        renewIPadress()
        continue
    except requests.Timeout as e:
        print("OOPS!! Timeout Error")
        print(str(e))
        renewIPadress()
        continue
    except requests.RequestException as e:
        print("OOPS!! General Error")
        print(str(e))
        renewIPadress()
        continue
    except KeyboardInterrupt:
        print("Someone closed the program")

Here renewIPadress() is a user define function which can change the IP address if it get blocked. You can go without this function.

You don't necessarily need to have an HTML page. Open Chrome, press Ctrl+Shift+j and it opens the JavaScript console where you can write and test your code.

I had similar issue on MacBook Pro, I just followed the below link and issue got resolved. https://projectlombok.org/setup/eclipse

Steps followed:-

• Download the lombok.jar
• Double click on this jar
• This jar will try to find the eclipse installed on the machine, but in my case it was not able to identify the eclipse though I installed on it, this could be due to softlink to the eclipse path.
• I just specified the location of the eclipse ini file by clicking "Specify location" button
• This jar automatically updated the entry in eclipse.ini file for javaagent
  • I added the same jar to the classpath of the project in the eclipse
  • Restarted my eclipse

I also got this error, but for a .h file. The fix was to go into the file Properties (via Solution Explorer's file popup menu) and set the file type correctly. It was set to C/C++ Compiler instead of the correct C/C++ header.

Double click on the home button and then click and hold the icon like a normal phone and then click close I believe.

This works for me across all browsers greater than version 6 (IE7, 8, 9, 10, etc, Chrome 3 up to what it is now, and FF ver 3 up to what it is now):

//test if running in IE or not
        function isIE () {
            var myNav = navigator.userAgent.toLowerCase();
            return (myNav.indexOf('msie') != -1 || myNav.indexOf('trident') != -1) ? true : false;
        }

You can also use the NSString class methods which will also create an autoreleased instance and have more options like string formatting:

NSString *myString = [NSString stringWithString:@"abc"];
NSString *myString = [NSString stringWithFormat:@"abc %d efg", 42];

What about an onclick function:

    <form id="form">
    <input type="text" name="firstInput">
    <button type="button" name="namebutton" 
           onClick="$('#gif').css('visibility', 'visible');
                    $('#form').submit();">
    </form>

Of course you can put this in a function and then trigger it with an onClick

You can update with a join if you only affect one table like this:

UPDATE table1 
SET table1.name = table2.name 
FROM table1, table2 
WHERE table1.id = table2.id 
AND table2.foobar ='stuff'

But you are trying to affect multiple tables with an update statement that joins on multiple tables. That is not possible.

However, updating two tables in one statement is actually possible but will need to create a View using a UNION that contains both the tables you want to update. You can then update the View which will then update the underlying tables.

SQL JOINS

But this is a really hacky parlor trick, use the transaction and multiple updates, it's much more intuitive.

Another approach in integration testing is to define a new Configuration class and provide it as your @ContextConfiguration. Into the configuration you will be able to mock your beans and also you must define all types of beans which you are using in test/s flow. To provide an example :

@RunWith(SpringRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class MockTest{
 @Configuration
 static class ContextConfiguration{
 // ... you beans here used in test flow
 @Bean
    public MockMvc mockMvc() {
        return MockMvcBuilders.standaloneSetup(/*you can declare your controller beans defines on top*/)
                .addFilters(/*optionally filters*/).build();
    }
 //Defined a mocked bean
 @Bean
    public MyService myMockedService() {
        return Mockito.mock(MyService.class);
    }
 }

 @Autowired
 private MockMvc mockMvc;

 @Autowired
 MyService myMockedService;

 @Before
 public void setup(){
  //mock your methods from MyService bean 
  when(myMockedService.myMethod(/*params*/)).thenReturn(/*my answer*/);
 }

 @Test
 public void test(){
  //test your controller which trigger the method from MyService
  MvcResult result = mockMvc.perform(get(CONTROLLER_URL)).andReturn();
  // do your asserts to verify
 }
}

This should work:

s=json.dumps(variables)
variables2=json.loads(s)
assert(variables==variables2)

Use below css to align Label with Checkbox

    .chkbox label
            {
                position: relative;
                top: -2px;
            }

<div class="chkbox">
<asp:CheckBox ID="Ckbox" runat="server" Text="Check Box Alignment"/>
</div>

You can have an iframe inside the modal markup and give the src attribute of it as the link to your pdf. On click of the link you can show this modal markup.

Try using ReadSettings:

from readsettings import ReadSettings
data = ReadSettings("settings.json") # Load or create any json, yml, yaml or toml file
data["name"] = "value" # Set "name" to "value"
data["name"] # Returns: "value"

I have a longer test to try. This takes an average of 160 ns to read each line as add it to a List (Which is likely to be what you intended as dropping the newlines is not very useful.

public static void main(String... args) throws IOException {
    final int runs = 5 * 1000 * 1000;

    final ServerSocket ss = new ServerSocket(0);
    new Thread(new Runnable() {
        @Override
        public void run() {
            try {
                Socket serverConn = ss.accept();
                String line = "Hello World!\n";
                BufferedWriter br = new BufferedWriter(new OutputStreamWriter(serverConn.getOutputStream()));
                for (int count = 0; count < runs; count++)
                    br.write(line);
                serverConn.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }).start();

    Socket conn = new Socket("localhost", ss.getLocalPort());

    long start = System.nanoTime();
    BufferedReader in = new BufferedReader(new InputStreamReader(conn.getInputStream()));
    String line;

    List<String> responseData = new ArrayList<String>();
    while ((line = in.readLine()) != null) {
        responseData.add(line);
    }
    long time = System.nanoTime() - start;
    System.out.println("Average time to read a line was " + time / runs + " ns.");
    conn.close();
    ss.close();
}

prints

Average time to read a line was 158 ns.

If you want to build a StringBuilder, keeping newlines I would suggets the following approach.

Reader r = new InputStreamReader(conn.getInputStream());
String line;

StringBuilder sb = new StringBuilder();
char[] chars = new char[4*1024];
int len;
while((len = r.read(chars))>=0) {
    sb.append(chars, 0, len);
}

Still prints

Average time to read a line was 159 ns.

In both cases, the speed is limited by the sender not the receiver. By optimising the sender, I got this timing down to 105 ns per line.

In my case, I was able to find issue with ScriptManager by setting Debug=true in web.config file

Because GFW forbidden you to access golang.org ! And when i use the proxy , it can work well.

you can look at the information using command go get -v -u golang.org/x/oauth2

The '\0' inside character literals and string literals stands for the character with the code zero. The meaning in C and in Objective C is identical.

To illustrate, you can use \0 in an array initializer to construct an array equivalent to a null-terminated string:

char str1[] = "Hello";
char str2[] = {'H', 'e', 'l', 'l', 'o', '\0'};

In general, you can use \ooo to represent an ASCII character in octal notation, where os stand for up to three octal digits.

I've tried this:

<a href="whatsapp://send?abid=phonenumber&text=Hello%2C%20World!">whatsapp</a>

changing 'phonenumber' into a specific phonenumber. This doesn't work completely, but when they click on the link it does open whatsapp and if they click on a contact the message is filled in.

If you want to open a specific person in chat you can, but without text filled in.

<a href="intent://send/phonenumber#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end">test</a>

You'll probably have to make a choice between the two.

(I tested this with google chrome on an android phone)

If table_2 is empty, then try the following insert statement:

insert into table_2 (itemid,location1) 
select itemid,quantity from table_1 where locationid=1

If table_2 already contains the itemid values, then try this update statement:

update table_2 set location1=
(select quantity from table_1 where locationid=1 and table_1.itemid = table_2.itemid)

You can try this too, If you don't want to do this by your method.

    Arrays.sort(arr);
    System.out.println("Min value "+arr[0]);
    System.out.println("Max value "+arr[arr.length-1]);
