I have the same problem now , I have foreign key and i need put it as nullable, to solve this problem you should put

    modelBuilder.Entity<Country>()
        .HasMany(c => c.Users)
        .WithOptional(c => c.Country)
        .HasForeignKey(c => c.CountryId)
        .WillCascadeOnDelete(false);

in DBContext class I am sorry for answer you very late :)

In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.

In case of entity framework FK in dependent must also be its PK so in your case you should use:

public class Boo
{
    [Key, ForeignKey("Foo")]
    public string BooId{get;set;}
    public Foo Foo{get;set;}
}

Or fluent mapping

modelBuilder.Entity<Foo>()
            .HasOptional(f => f.Boo)
            .WithRequired(s => s.Foo);

I had the same problem and I think I have the solution.

If your field Application in table Library has a foreign key that references a field in another table (named Application I would bet), then your field Application in table Library has to have a foreign key to table Application too.

After that you can do your composed foreign key.

Excuse my poor english, and sorry if I'm wrong.

The ON UPDATE and ON DELETE specify which action will execute when a row in the parent table is updated and deleted. The following are permitted actions : NO ACTION, CASCADE, SET NULL, and SET DEFAULT.

Delete actions of rows in the parent table

If you delete one or more rows in the parent table, you can set one of the following actions:

• ON DELETE NO ACTION: SQL Server raises an error and rolls back the delete action on the row in the parent table.
• ON DELETE CASCADE: SQL Server deletes the rows in the child table that is corresponding to the row deleted from the parent table.
• ON DELETE SET NULL: SQL Server sets the rows in the child table to NULL if the corresponding rows in the parent table are deleted. To execute this action, the foreign key columns must be nullable.
• ON DELETE SET DEFAULT: SQL Server sets the rows in the child table to their default values if the corresponding rows in the parent table are deleted. To execute this action, the foreign key columns must have default definitions. Note that a nullable column has a default value of NULL if no default value specified. By default, SQL Server appliesON DELETE NO ACTION if you don’t explicitly specify any action.

Update action of rows in the parent table

If you update one or more rows in the parent table, you can set one of the following actions:

• ON UPDATE NO ACTION: SQL Server raises an error and rolls back the update action on the row in the parent table.
• ON UPDATE CASCADE: SQL Server updates the corresponding rows in the child table when the rows in the parent table are updated.
• ON UPDATE SET NULL: SQL Server sets the rows in the child table to NULL when the corresponding row in the parent table is updated. Note that the foreign key columns must be nullable for this action to execute.
• ON UPDATE SET DEFAULT: SQL Server sets the default values for the rows in the child table that have the corresponding rows in the parent table updated.

FOREIGN KEY (foreign_key_columns)
    REFERENCES parent_table(parent_key_columns)
    ON UPDATE <action> 
    ON DELETE <action>;

See the reference tutorial.

_{Old question but adding answer so that one can get help}

Its two step process:

Suppose, a table1 has a foreign key with column name fk_table2_id, with constraint name fk_name and table2 is referred table with key t2 (something like below in my diagram).

   table1 [ fk_table2_id ] --> table2 [t2]

First step, DROP old CONSTRAINT: (reference)

ALTER TABLE `table1` 
DROP FOREIGN KEY `fk_name`;  

_{notice constraint is deleted, column is not deleted}

Second step, ADD new CONSTRAINT:

ALTER TABLE `table1`  
ADD CONSTRAINT `fk_name` 
    FOREIGN KEY (`fk_table2_id`) REFERENCES `table2` (`t2`) ON DELETE CASCADE;  

_{adding constraint, column is already there}

Example:

I have a UserDetails table refers to Users table:

mysql> SHOW CREATE TABLE UserDetails;
:
:
 `User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`)
:
:

First step:

mysql> ALTER TABLE `UserDetails` DROP FOREIGN KEY `FK_User_id`;
Query OK, 1 row affected (0.07 sec)  

Second step:

mysql> ALTER TABLE `UserDetails` ADD CONSTRAINT `FK_User_id` 
    -> FOREIGN KEY (`User_id`) REFERENCES `Users` (`User_id`) ON DELETE CASCADE;
Query OK, 1 row affected (0.02 sec)  

result:

mysql> SHOW CREATE TABLE UserDetails;
:
:
`User_id` int(11) DEFAULT NULL,
  PRIMARY KEY (`Detail_id`),
  KEY `FK_User_id` (`User_id`),
  CONSTRAINT `FK_User_id` FOREIGN KEY (`User_id`) REFERENCES 
                                       `Users` (`User_id`) ON DELETE CASCADE
:

If the table has already been created:

First do:

ALTER TABLE `table1_name` ADD UNIQUE( `column_name`);

Then:

ALTER TABLE `table1_name` ADD FOREIGN KEY (`column_name`) REFERENCES `table2_name`(`column_name`);

The related name parameter is actually an option. If we do not set it, Django automatically creates the other side of the relation for us. In the case of the Map model, Django would have created a map_set attribute, allowing access via m.map_set in your example(m being your class instance). The formula Django uses is the name of the model followed by the string _set. The related name parameter thus simply overrides Django’s default rather than providing new behavior.

Try to get an idea about what a first responder is in iOS view hierarchy. When your textfield becomes active(or first responder) when you touch inside it (or pass it the messasge becomeFirstResponder programmatically), it presents the keyboard. So to remove your textfield from being the first responder, you should pass the message resignFirstResponder to it there.

[textField resignFirstResponder];

And to hide the keyboard on its return button, you should implement its delegate method textFieldShouldReturn: and pass the resignFirstResponder message.

- (BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    return YES;
}

You can also accomplish this using the sqldf package as shown below:

library(sqldf)

x <- read.table(text='Name     Month  Rate1     Rate2
Aira       1      12        23
                Aira       2      18        73
                Aira       3      19        45
                Ben        1      53        19
                Ben        2      22        87
                Ben        3      19        45
                Cat        1      22        87
                Cat        2      67        43
                Cat        3      45        32', header=TRUE)

sqldf("
select 
  Name
  ,avg(Rate1) as Rate1_float
  ,avg(Rate2) as Rate2_float
  ,avg(Rate1) as Rate1
  ,avg(Rate2) as Rate2
from x
group by 
  Name
")

#  Name Rate1_float Rate2_float Rate1 Rate2
#1 Aira    16.33333    47.00000    16    47
#2  Ben    31.33333    50.33333    31    50
#3  Cat    44.66667    54.00000    44    54

I am a recent convert to dplyr as shown in other answers, but sqldf is nice as most data analysts/data scientists/developers have at least some fluency in SQL. In this way, I think it tends to make for more universally readable code than dplyr or other solutions presented above.

UPDATE: In responding to the comment below, I attempted to update the code as shown above. However, the behavior was not as I expected. It seems that the column definition (i.e. int vs float) is only carried through when the column alias matches the original column name. When you specify a new name, the aggregate column is returned without rounding.

Well, there really is a lot to this. I'm assuming you have an account on http://github.com/. If not, go get one.

After that, you really can just follow their guide, its very simple and easy and the explanation is much more clear than mine: http://help.github.com/ >> http://help.github.com/mac-set-up-git/

To answer your specific question: You upload files to github through the git push command after you have added your files you needed through git add 'files' and commmited them git commit -m "my commit messsage"

I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader's fault. Try measuring this:

InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing

I think you'll find it's almost exactly the same time as when you're parsing the text.

Note that you should also give InputStreamReader an appropriate encoding - the platform default encoding is almost certainly not what you should be using.

FIRST, if you want to be able to access man1.py from man1test.py AND manModules.py from man1.py, you need to properly setup your files as packages and modules.

Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A.

...

When importing the package, Python searches through the directories on sys.path looking for the package subdirectory.

The __init__.py files are required to make Python treat the directories as containing packages; this is done to prevent directories with a common name, such as string, from unintentionally hiding valid modules that occur later on the module search path.

You need to set it up to something like this:

man
|- __init__.py
|- Mans
   |- __init__.py
   |- man1.py
|- MansTest
   |- __init.__.py
   |- SoftLib
      |- Soft
         |- __init__.py
         |- SoftWork
            |- __init__.py
            |- manModules.py
      |- Unittests
         |- __init__.py
         |- man1test.py

SECOND, for the "ModuleNotFoundError: No module named 'Soft'" error caused by from ...Mans import man1 in man1test.py, the documented solution to that is to add man1.py to sys.path since Mans is outside the MansTest package. See The Module Search Path from the Python documentation. But if you don't want to modify sys.path directly, you can also modify PYTHONPATH:

sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.

THIRD, for from ...MansTest.SoftLib import Soft which you said "was to facilitate the aforementioned import statement in man1.py", that's now how imports work. If you want to import Soft.SoftLib in man1.py, you have to setup man1.py to find Soft.SoftLib and import it there directly.

With that said, here's how I got it to work.

man1.py:

from Soft.SoftWork.manModules import *
# no change to import statement but need to add Soft to PYTHONPATH

def foo():
    print("called foo in man1.py")
    print("foo call module1 from manModules: " + module1())

man1test.py

# no need for "from ...MansTest.SoftLib import Soft" to facilitate importing..
from ...Mans import man1

man1.foo()

manModules.py

def module1():
    return "module1 in manModules"

Terminal output:

$ python3 -m man.MansTest.Unittests.man1test
Traceback (most recent call last):
  ...
    from ...Mans import man1
  File "/temp/man/Mans/man1.py", line 2, in <module>
    from Soft.SoftWork.manModules import *
ModuleNotFoundError: No module named 'Soft'

$ PYTHONPATH=$PYTHONPATH:/temp/man/MansTest/SoftLib
$ export PYTHONPATH
$ echo $PYTHONPATH
:/temp/man/MansTest/SoftLib
$ python3 -m man.MansTest.Unittests.man1test
called foo in man1.py
foo called module1 from manModules: module1 in manModules 

As a suggestion, maybe re-think the purpose of those SoftLib files. Is it some sort of "bridge" between man1.py and man1test.py? The way your files are setup right now, I don't think it's going to work as you expect it to be. Also, it's a bit confusing for the code-under-test (man1.py) to be importing stuff from under the test folder (MansTest).

I believe telnet 74.255.12.25 8089 . Why don't u try both

It could raise the concern if you're either:

Case 1: Downgrading/ upgrading any PHP version.
Case 2: Enabling/Disabling (Switching) between PHP versions.

Here are some recommended commands I found helpful to fix these concerns:

Message 1: The mbstring extension is missing.......

sudo apt-get install php7.1-mbstring  

Message 2: The mysqli extension is missing.......

sudo apt-get install php7.1-mysqli

Note: Tested with PHP version 7.1. Change PHP version as per requirement.

The performance is almost a 100% identical. You can check this out by opening the class in Reflector.net

This is the This indexer:

public TValue this[TKey key]
{
    get
    {
        int index = this.FindEntry(key);
        if (index >= 0)
        {
            return this.entries[index].value;
        }
        ThrowHelper.ThrowKeyNotFoundException();
        return default(TValue);
    }
    set
    {
        this.Insert(key, value, false);
    }
}

And this is the Add method:

public void Add(TKey key, TValue value)
{
    this.Insert(key, value, true);
}

I won't post the entire Insert method as it's rather long, however the method declaration is this:

private void Insert(TKey key, TValue value, bool add)

And further down in the function, this happens:

if ((this.entries[i].hashCode == num) && this.comparer.Equals(this.entries[i].key, key))
{
    if (add)
    {
        ThrowHelper.ThrowArgumentException(ExceptionResource.Argument_AddingDuplicate);
    }

Which checks if the key already exists, and if it does and the parameter add is true, it throws the exception.

So for all purposes and intents the performance is the same.

Like a few other mentions, it's all about whether you need the check, for attempts at adding the same key twice.

Sorry for the lengthy post, I hope it's okay.

I've just gone through that process again. Always end up cloning the repo locally, upload the folder I want to have in that repo to that cloned location, commit the changes and then push it.

Note that if you're dealing with large files, you'll need to consider using something like Git LFS.

Yea these are great if your using a simple ORM like Dapper.

If your using .Net you can generate an XSD file at run time with any DataSet using the WriteXmlSchema method. http://msdn.microsoft.com/en-us/library/xt7k72x8(v=vs.110).aspx

Like this:

using (SqlConnection cnn = new SqlConnection(mConnStr)) {
DataSet Data = new DataSet();
cnn.Open();
string sql = "SELECT * FROM Person";

using (SqlDataAdapter Da = new SqlDataAdapter(sql, cnn))
{
try
{
    Da.Fill(Data);
    Da.TableMappings.Add("Table", "Person");
    Data.WriteXmlSchema(@"C:\Person.xsd");
}
catch (Exception ex)
{ MessageBox.Show(ex.Message); }
}
cnn.Close();

From there you can use xsd.exe to create a class that's XML serializable from the Developer Command Prompt. http://msdn.microsoft.com/en-us/library/x6c1kb0s(v=vs.110).aspx

like this:

xsd C:\Person.xsd /classes /language:CS

To make all lines taller, to look the same as the line with the superscript, define a larger line-height for the entire paragraph

<p style='line-height:150%'>

or whatever value gives the effect you desire.

It may look strange, but that's how you described your requirements.

EDIT: In order to make all lines look the same when only one needs more vertical space than the others, ALL lines in the paragraph will have to be taller.

This, as I said, may not an attractive solution. Maybe something can be done with a span making just the text with the sub/superscript smaller, apart from that I don't believe what you want can be achieved. But I'd like to see someone else's solution.

EDIT2: Incidentally, I've tried a small html file containing

<html>
<head>
<title>line-height</title>
<style>
p {
    line-height : 1.5em;
    width : 25em;
}
</style>
</head>
<body>
<p>Mary had a little lamb, its fleece<sup>1</sup> was white as snow, 
and everywhere that Mary went, the lamb<sub>2</sub> was sure to go.
</p>
</body>
</html>

And the lines are all the same height in FF3.0.14 and Konqueror (I can't speak for other browsers)

Unlike isfile(), exists() will return True for directories. So depending on if you want only plain files or also directories, you'll use isfile() or exists(). Here is some simple REPL output:

>>> os.path.isfile("/etc/password.txt")
True
>>> os.path.isfile("/etc")
False
>>> os.path.isfile("/does/not/exist")
False
>>> os.path.exists("/etc/password.txt")
True
>>> os.path.exists("/etc")
True
>>> os.path.exists("/does/not/exist")
False

It could depend on your framework. (for each of them could exist an easier solution).

But to answer your question: there are a lot of external libraries for this functionality. Look here how to use apache commons fileupload.

COM interop. Especially IUnknown. It was designed specially for it.

Date d1 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date1));
Date d2 = new SimpleDateFormat("yyyy-M-dd").parse((String) request.
            getParameter(date2));

long diff = d2.getTime() - d1.getTime();

System.out.println("Difference between  " + d1 + " and "+ d2+" is "
        + (diff / (1000 * 60 * 60 * 24)) + " days.");

Try this piece of code:

$first = $string[0]; 
if($first == 'A' || $first == 'E' || $first == 'I' || $first == 'O' || $first == 'U') {
   $v='starts with vowel';
} 
else {
   $v='does not start with vowel';
}

Its pretty simple (Required: Minimum API 21)...

1. Go to your xml and select the EditText field
2. On the right side, you can see the 'Attributes' window. Select 'View All Attributes'
3. Just search for 'tint'
4. And add/change the 'backgroundTint' to a desired color hex (say #FF0000)

Keep Coding........ :)

If you add [hidden]="true" to div, the actual thing that happens is adding a class [hidden] to this element conditionally with display: none

Please check the style of the element in the browser to ensure no other style affect the display property of an element like this:

If you found display of [hidden] class is overridden, you need to add this css code to your style:

[hidden] {
    display: none !important;
}

I have qt4 installed. I found that using the following path worked for me, despite 'which qmake' returning /usr/bin/qmake, which is just a link to qtchooser anyway.

The following path works for me, on a 64 bit system. Running from the full path of:

/usr/lib/x86_64-linux-gnu/qt4/bin/qmake

As a supplement to the other answers, here is Microsoft's guidance for user agent strings for its browsers. The user agent strings differ by browser (Internet Explorer and Edge) and operating system (Windows 7, 8, 10 and Windows Phone).

For example, here is the user agent string for Internet Explorer 11 on Windows 10:

Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko 

and for Internet Explorer for Windows Phone 8.1 Update:

Mozilla/5.0 (Mobile; Windows Phone 8.1; Android 4.0; ARM; Trident/7.0; Touch; rv:11.0; IEMobile/11.0; NOKIA; Lumia 520) like iPhone OS 7_0_3 Mac OS X AppleWebKit/537 (KHTML, like Gecko) Mobile Safari/537

Templates are given for the user agent strings for the Edge browser for Desktop, Mobile and WebView. See this answer for some Edge user agent string examples.

Finally, another page on MSDN provides guidance for IE11 on older desktop operating systems.

IE11 on Windows 8.1:

Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko

and IE11 on Windows 7:

Mozilla/5.0 (Windows NT 6.1; Trident/7.0; rv:11.0) like Gecko

You can query the data dictionary/catalog views to find out when an object was created as well as the time of last DDL involving the object (example: alter table)

select * 
  from all_objects 
 where owner = '<name of schema owner>'
   and object_name = '<name of table>'

The column "CREATED" tells you when the object was created. The column "LAST_DDL_TIME" tells you when the last DDL was performed against the object.

As for when a particular row was inserted/updated, you can use audit columns like an "insert_timestamp" column or use a trigger and populate an audit table

Sounds correct but some issues maybe creates executing this query: I would suggest:

$this->db->where( "$accommodation BETWEEN $minvalue AND $maxvalue", NULL, FALSE );

Alternatively YUI has http://yuilibrary.com/yui/docs/api/classes/QueryString.html#method_stringify.

For example:

var data = { one: 'first', two: 'second' };
var result = Y.QueryString.stringify(data);

This problem mostly occurs due to the error in setText() method

Solution is simple put your Integer value by converting into string type as

textview.setText(Integer.toString(integer_value));

psql -h <host> -p <port> -U <user> -d <db>

and update /var/lib/pgsql/10/data/pg_hba.conf to change the auth method to cert. Check the following link for more information:

https://www.postgresql.org/docs/9.1/auth-pg-hba-conf.html

First, clone the repository using git, e.g. with:

git clone git://github.com/facebook/facebook-ios-sdk.git

That downloads the complete history of the repository, so you can switch to any version. Next, change into the newly cloned repository:

cd facebook-ios-sdk

... and use git checkout <COMMIT> to change to the right commit:

git checkout 91f25642453

That will give you a warning, since you're no longer on a branch, and have switched directly to a particular version. (This is known as "detached HEAD" state.) Since it sounds as if you only want to use this SDK, rather than actively develop it, this isn't something you need to worry about, unless you're interested in finding out more about how git works.

As at PHP 7.3:

curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BEARER);
curl_setopt($ch,CURLOPT_XOAUTH2_BEARER,$bearerToken);

I encountered the exact same problem today, Ryan.

In my src (or your root) directory, my log4j.properties file now has the following addition

# https://issues.apache.org/jira/browse/AXIS2-4363

Thanks for the heads up as to how to do this, Benjamin.

You might be missing an intermediate certificate in your cert file. If you have already visited another website which has the same certificate seller, the intermediate certificate is remembered in your browser. This might not - or even better - will not be the case with every visitor to your website. To solve a missing intermediate certificate in the SSL connection, you will need to add the intermediate certificate to your own certificate file.

GoDaddy has some info on the intermediate certificates (but the best source is always your certificate provider): http://support.godaddy.com/help/article/868/what-is-an-intermediate-certificate

I once had this issue of an intermediate cert (with Commodo too) and had to combine my own cert file with the intermediate CA's to work. Once done no errors occurred anymore.

Installation instructions per webserver by Godaddy: http://support.godaddy.com/help/article/5346/installing-an-ssl-server-instructions?locale=en

And here is a list of the most common installation guides by Commodo themselves: https://support.comodo.com/index.php?/Default/Knowledgebase/Article/View/1145/0/how-do-i-make-my-own-bundle-file-from-crt-files

Depending on what webserver you are using, you'll need to specify all certificates (domain certificate, intermediate and root) or combine them into one (eg for Nginx) in the order:

1. domain certificate
2. intermediate certificate
3. root certificate

An easy way of doing this in an SSH terminal is by typing:

cat domainfile intermediatefile rootfile > targetfile

Certificate test tool

If you encounter further problems or are unsure whether the certificate is correct, please try an online tool to verify your SSL certificate. For instance: networking4all.com/en/ssl+certificates/quickscan

SNI support for android 2.2 and lower

Please note android 2.2 (and probably older) do not support SNI, which allows multiple SSL certificates for different hostnames to work without issues on one single IP address. Thanks to @technyquist for providing that information. Please review this SO question about SNI for more information on this issue.

For those who uses an opener, you can achieve the same thing based on Enno Gröper's great answer:

import urllib2, ssl

ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE

opener = urllib2.build_opener(urllib2.HTTPSHandler(context=ctx), your_first_handler, your_second_handler[...])
opener.addheaders = [('Referer', 'http://example.org/blah.html')]

content = opener.open("https://localhost/").read()

And then use it as before.

According to build_opener and HTTPSHandler, a HTTPSHandler is added if ssl module exists, here we just specify our own instead of the default one.

Evil hack ...

Just to add, we can use array as well:

int i, array[4];
printf("Enter Four Ints: ");
for(i=0; i<4; i++) {
    scanf("%d", &array[i]);
}

Number (1): The IP was incorrect - is the correct answer. The /etc/hosts file (a.k.a. C:\Windows\system32\drivers\etc\hosts ) had an incorrect entry for the local machine name. Corrected the 'hosts' file and Camel runs very well. Thanks for the pointer.

2 points in addition to all other good answers:

1:

what are the Grant Tables?

from dev.mysql.com

The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.

clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables

2:

note that if you perform:

UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';

and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:

mysql -u someuser -p

your access will be denied by your new password until you perform :

FLUSH PRIVILEGES;

You probably just need to see the ASCII and EXTENDED ASCII character sets. As far as I know any of these are allowed in a char/varchar field.

If you use nchar/nvarchar then it's pretty much any character in any unicode set in the world.

@Query(value = "delete from addresses u where u.ADDRESS_ID LIKE %:addressId%", nativeQuery = true)
void deleteAddressByAddressId(@Param("addressId") String addressId);

The common approach is to use the default value as a label, and then remove it when the field gains the focus.

I really dislike this approach as it has accessibility and usability implications.

Instead, I would start by using a standard element next to the field.

Then, if JavaScript is active, set a class on an ancestor element which causes some new styles to apply that:

• Relatively position a div that contains the input and label
• Absolutely position the label
• Absolutely position the input on top of the label
• Remove the borders of the input and set its background-color to transparent

Then, and also whenever the input loses the focus, I test to see if the input has a value. If it does, ensure that an ancestor element has a class (e.g. "hide-label"), otherwise ensure that it does not have that class.

Whenever the input gains the focus, set that class.

The stylesheet would use that classname in a selector to hide the label (using text-indent: -9999px; usually).

This approach provides a decent experience for all users, including those with JS disabled and those using screen readers.

With Vim 8.0 or later you can run a terminal emulator in a vim window by using the terminal feature. BTW if you want to simulate modern IDE terminal (like VSCode integrated terminal) in gVim or MacVim, you can put the following configuration in you vimrc.

set shell=/path/to/shell

" Make sure to replace `sh.exe` in BufNr("sh.exe") with your shell executable.
nnoremap <expr> <space> BufNr("sh.exe") > 0 ? (&buftype == 'terminal' ? '<c-^>' : ':b '. BufNr("sh.exe") . '<cr>') : ':terminal ++curwin<cr>'

function! BufNr(pattern)
  let bufcount = bufnr("$")
  let currbufnr = 1
  let nummatches = 0
  let firstmatchingbufnr = 0
  while currbufnr <= bufcount
    if(bufexists(currbufnr))
      let currbufname = bufname(currbufnr)
      if(match(currbufname, a:pattern) > -1)
        let nummatches += 1
        let firstmatchingbufnr = currbufnr
      endif
    endif
    let currbufnr = currbufnr + 1
  endwhile
  return firstmatchingbufnr
endf

Now you can use space in normal mode (or whatever mapping you chosen) to:

1. Open a terminal in current window if terminal doesn't exists yet.
2. Switch to terminal buffer if current buffer is not a terminal type.
3. Switch to previous buffer if current buffer is a terminal buffer.

date = new DateTime(date.year, date.month, date.day, HH, MM, SS);

If there are are no duplicate elements or you don't care about them, then you can use the Set class:

a1 = Set.new [5, 1, 6, 14, 2, 8]
a2 = Set.new [2, 6, 15]
a1.subset?(a2)
=> false

Behind the scenes this uses

all? { |o| set.include?(o) }

For multiple selection dropdown list,cannot accomplish it directly using dropdown..Can be done in similar ways..

Either you have to use checkbox list or listbox (ajax inclusive)

Binary strings store raw-byte data, whilst character strings store text. Use binary data when storing hexi-decimal values such as SID, GUID and so on. The uniqueidentifier data type contains a globally unique identifier, or GUID. This value is derived by using the NEWID() function to return a value that is unique to all objects. It's stored as a binary value but it is displayed as a character string.

Here is an example.

USE AdventureWorks2008R2;
GO
CREATE TABLE MyCcustomerTable
(
    user_login   varbinary(85) DEFAULT SUSER_SID()
    ,data_value   varbinary(1)
);
GO

INSERT MyCustomerTable (data_value)
    VALUES (0x4F);
GO

Applies to: SQL Server The following example creates the cust table with a uniqueidentifier data type, and uses NEWID to fill the table with a default value. In assigning the default value of NEWID(), each new and existing row has a unique value for the CustomerID column.

-- Creating a table using NEWID for uniqueidentifier data type.  
CREATE TABLE cust  
(

Browser sniffing should generally be avoided, feature detection is much better, but sometimes you have to do it. For instance in my case Windows 8 Tablets overlaps the browser window with a soft keyboard; Ridiculous I know, but sometimes you have to deal with reality.

So you would measure 'navigator.userAgent' as with regular JavaScript (Please don't sink into the habit of treating Angular as something distinct from JavaScript, use plain JavaScript if possible it will lead to less future refactoring).

However for testing you want to use injected objects rather than global ones. Since '$location' doesn't contain the userAgent the simple trick is to use '$window.location.userAgent'. You can now write tests that inject a $window stub with whatever userAgent you wan't to simulate.

I haven't used it for years, but Modernizr's a good source of code for checking features. https://github.com/Modernizr/Modernizr/issues/878#issuecomment-41448059

It often ends up being easier to load your data into the database, even if it is only to run a quick query. Hard-coded data seems quick to enter, but it quickly becomes a pain if you start having to make changes.

However, if you want to code the names directly into your query, here is a cleaner way to do it:

with names (fname,lname) as (
    values
        ('John','Smith'),
        ('Mary','Jones')
)
select city from user
    inner join names on
        fname=firstName and
        lname=lastName;

The advantage of this is that it separates your data out of the query somewhat.

(This is DB2 syntax; it may need a bit of tweaking on your system).

Put your params in the data part of the ajax call. See the docs. Like so:

$.ajax({
    url: "/TestPage.aspx",
    data: {"first": "Manu","Last":"Sharma"},
    success: function(response) {
        //Do Something
    },
    error: function(xhr) {
        //Do Something to handle error
    }
});

Assuming this branch isn't an external or a symlink, removing the branch should be as simple as:

svn rm branches/< mybranch >

svn ci -m "message"

If you'd like to do this in the repository then update to remove it from your working copy you can do something like:

svn rm http://< myurl >/< myrepo >/branches/< mybranch >

Then run:

svn update

The problem with both iDevlop's and Ashok's answers is that the fundamental problem is an Excel design flaw (apparently) in which the Open method fails to respect the Application.ScreenUpdating setting of False. Consequently, setting it to False is of no benefit to this problem.

If Patrick McDonald's solution is too burdensome due to the overhead of starting a second instance of Excel, then the best solution I've found is to minimize the time that the opened workbook is visible by re-activating the original window as quickly as possible:

Dim TempWkBk As Workbook
Dim CurrentWin As Window

Set CurrentWin = ActiveWindow
Set TempWkBk = Workbooks.Open(SomeFilePath)
CurrentWin.Activate      'Allows only a VERY brief flash of the opened workbook
TempWkBk.Windows(1).Visible = False 'Only necessary if you also need to prevent
                                    'the user from manually accessing the opened
                                    'workbook before it is closed.

'Operate on the new workbook, which is not visible to the user, then close it...

you need to post plain javascript object, nothing else

           var request = $http({
                method: "post",
                url: "process.cfm",
                transformRequest: transformRequestAsFormPost,
                data: { id: 4, name: "Kim" }
            });

            request.success(
                function( data ) {
                    $scope.localData = data;
                }
            );

if you have php as back-end then you will need to do some more modification.. checkout this link for fixing php server side

This example is a Sum for Date time and Time Zone(String Values)

String DateVal = "2015-03-26 12:00:00";
String TimeVal = "02:00:00";

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
SimpleDateFormat sdf2 = new SimpleDateFormat("HH:mm:ss");

Date reslt = sdf.parse( DateVal );
Date timeZ = sdf2.parse( TimeVal );
//Increase Date Time
reslt.setHours( reslt.getHours() + timeZ.getHours());
reslt.setMinutes( reslt.getMinutes() + timeZ.getMinutes());
reslt.setSeconds( reslt.getSeconds() + timeZ.getSeconds());

System.printLn.out( sdf.format(reslt) );//Result(+2 Hours):  2015-03-26 14:00:00 

Thanks :)

I prefer a non blocking approach:

            Dim aw1=GenerateCodeAsync().GetAwaiter()
            While Not aw1.IsCompleted
                Application.DoEvents()
            End While

Don't forget to add the

CONFIG += console 

flag in the qmake .pro file.

For the rest is just using some of Qt classes. One way I use it is to spawn processes cross-platform.

You're looking for:

.is(':visible')

Although you should probably change your selector to use jQuery considering you're using it in other places anyway:

if($('#testElement').is(':visible')) {
    // Code
}

It is important to note that if any one of a target element's parent elements are hidden, then .is(':visible') on the child will return false (which makes sense).

jQuery 3

:visible has had a reputation for being quite a slow selector as it has to traverse up the DOM tree inspecting a bunch of elements. There's good news for jQuery 3, however, as this post explains (Ctrl + F for :visible):

Thanks to some detective work by Paul Irish at Google, we identified some cases where we could skip a bunch of extra work when custom selectors like :visible are used many times in the same document. That particular case is up to 17 times faster now!

Keep in mind that even with this improvement, selectors like :visible and :hidden can be expensive because they depend on the browser to determine whether elements are actually displaying on the page. That may require, in the worst case, a complete recalculation of CSS styles and page layout! While we don’t discourage their use in most cases, we recommend testing your pages to determine if these selectors are causing performance issues.

Expanding even further to your specific use case, there is a built in jQuery function called $.fadeToggle():

function toggleTestElement() {
    $('#testElement').fadeToggle('fast');
}

I am not sure about gson but this is how you do it with Jon.sample hope there must be similar way using gson

There are two ways to accomplish this,

1. LINQ to XML
2. XPath

The following are samples of using these approaches,

List<XElement> result = doc.Root.Element("emails").Elements("emailAddress").ToList();

If you use XPath, you need to do some manipulation with the IEnumerable:

IEnumerable<XElement> mails = ((IEnumerable)doc.XPathEvaluate("/emails/emailAddress")).Cast<XElement>();

Note that

var res = doc.XPathEvaluate("/emails/emailAddress");

results either a null pointer, or no results.

To have a direct link without redirection :

1. Use iTunes link maker http://itunes.apple.com/linkmaker/ to get the real direct link
2. Replace the http:// with itms-apps://
3. Open the link with [[UIApplication sharedApplication] openURL:url];

Be careful, those links only works on actual devices, not in simulator.

I found the simplest method, described in this article mentioned in Greg T's answer, was to create an App Password which is available after turning on 2FA for the account.

myaccount.google.com > Sign-in & security > Signing in to Google > App Passwords

This gives you an alternative password for the account, then you just configure nodemailer as a normal SMTP service.

var smtpTransport = nodemailer.createTransport({
    host: "smtp.gmail.com",
    port: 587,
    auth: {
        user: "[email protected]",
        pass: "app password"
    }
});

While Google recommend Oauth2 as the best option, this method is easy and hasn't been mentioned in this question yet.

Extra tip: I also found you can add your app name to the "from" address and GMail does not replace it with just the account email like it does if you try to use another address. ie.

from: 'My Pro App Name <[email protected]>'

Below command will push all the branches(including the ones which you have never checked-out but present in your git repo, you can see them by git branch -a)

git push origin '*:*'

NOTE: This command comes handy when you are migrating version control service(i.e migrating from Gitlab to GitHub)

Like this:

 str_repeat(' ', 5); // adds 5 spaces

There is the same problem in Linux OS. The issue is related on Windows OS, but Homestead is a Ubuntu VM, and the solution posted works strongly good in others SO. I applied the commands sugested by flik, and the problems was solved. I only used the following commands

I only used the following commands

rm -rf node_modules
npm cache clear --force

After

npm install cross-env
npm install 
npm run watch

It's working fine on linux Fedora 25.

From the JDK source:

static <T> Function<T, T> identity() {
    return t -> t;
}

So, no, as long as it is syntactically correct.

Go to the start menu. Open up cmd (command prompt) and type in the following.

wmic process list brief | find /i "tomcat"

This would tell you if the tomcat is running or not.

You can access rails app path using variable RAILS_ROOT.

For example:

render :file => "#{RAILS_ROOT}/public/layouts/mylayout.html.erb"

Final working solution:

 public static String getFileName(Uri uri) {
    try {
        String path = uri.getLastPathSegment();
        return path != null ? path.substring(path.lastIndexOf("/") + 1) : "unknown";

    } catch (Exception e) {
        e.printStackTrace();
    }

    return "unknown";
}

npm ci

Alternatively, as of npm cli v6.5.0 you can use the backronym:

npm clean-install

https://github.com/npm/cli/releases/tag/v6.5.0 https://github.com/npm/cli/commit/fc1a8d185fc678cdf3784d9df9eef9094e0b2dec

One thing I found confusing is that the "()" are grouping operators.

Here is your basic declared function.

Ex. 1:

var message = 'SO';

function foo(msg) {
    alert(msg);
}

foo(message);

Functions are objects, and can be grouped. So let's throw parens around the function.

Ex. 2:

var message = 'SO';

function foo(msg) {  //declares foo
    alert(msg);
}

(foo)(message);     // calls foo

Now instead of declaring and right-away calling the same function, we can use basic substitution to declare it as we call it.

Ex. 3.

var message = 'SO';

(function foo(msg) {
    alert(msg);
})(message);          // declares & calls foo

Finally, we don't have a need for that extra foo because we're not using the name to call it! Functions can be anonymous.

Ex. 4.

var message = 'SO';

(function (msg) {   // remove unnecessary reference to foo
    alert(msg);
})(message);

To answer your question, refer back to Example 2. Your first line declares some nameless function and groups it, but does not call it. The second line groups a string. Both do nothing. (Vincent's first example.)

(function (msg){alert(msg)});  
('SO');                       // nothing.

(foo); 
(msg); //Still nothing.

But

(foo)
(msg); //works

What I did to beable to use startssl certificates was quite easy. (on my rooted phone)

I copied /system/etc/security/cacerts.bks to my sdcard

Downloaded http://www.startssl.com/certs/ca.crt and http://www.startssl.com/certs/sub.class1.server.ca.crt

Went to portecle.sourceforge.net and ran portecle directly from the webpage.

Opened my cacerts.bks file from my sdcard (entered nothing when asked for a password)

Choose import in portacle and opened sub.class1.server.ca.crt, im my case it allready had the ca.crt but maybe you need to install that too.

Saved the keystore and copied it baxck to /system/etc/security/cacerts.bks (I made a backup of that file first just in case)

Rebooted my phone and now I can vist my site thats using a startssl certificate without errors.

Role of a metaclass' __call__() method when creating a class instance

If you've done Python programming for more than a few months you'll eventually stumble upon code that looks like this:

# define a class
class SomeClass(object):
    # ...
    # some definition here ...
    # ...

# create an instance of it
instance = SomeClass()

# then call the object as if it's a function
result = instance('foo', 'bar')

The latter is possible when you implement the __call__() magic method on the class.

class SomeClass(object):
    # ...
    # some definition here ...
    # ...

    def __call__(self, foo, bar):
        return bar + foo

The __call__() method is invoked when an instance of a class is used as a callable. But as we've seen from previous answers a class itself is an instance of a metaclass, so when we use the class as a callable (i.e. when we create an instance of it) we're actually calling its metaclass' __call__() method. At this point most Python programmers are a bit confused because they've been told that when creating an instance like this instance = SomeClass() you're calling its __init__() method. Some who've dug a bit deeper know that before __init__() there's __new__(). Well, today another layer of truth is being revealed, before __new__() there's the metaclass' __call__().

Let's study the method call chain from specifically the perspective of creating an instance of a class.

This is a metaclass that logs exactly the moment before an instance is created and the moment it's about to return it.

class Meta_1(type):
    def __call__(cls):
        print "Meta_1.__call__() before creating an instance of ", cls
        instance = super(Meta_1, cls).__call__()
        print "Meta_1.__call__() about to return instance."
        return instance

This is a class that uses that metaclass

class Class_1(object):

    __metaclass__ = Meta_1

    def __new__(cls):
        print "Class_1.__new__() before creating an instance."
        instance = super(Class_1, cls).__new__(cls)
        print "Class_1.__new__() about to return instance."
        return instance

    def __init__(self):
        print "entering Class_1.__init__() for instance initialization."
        super(Class_1,self).__init__()
        print "exiting Class_1.__init__()."

And now let's create an instance of Class_1

instance = Class_1()
# Meta_1.__call__() before creating an instance of <class '__main__.Class_1'>.
# Class_1.__new__() before creating an instance.
# Class_1.__new__() about to return instance.
# entering Class_1.__init__() for instance initialization.
# exiting Class_1.__init__().
# Meta_1.__call__() about to return instance.

Observe that the code above doesn't actually do anything more than logging the tasks. Each method delegates the actual work to its parent's implementation, thus keeping the default behavior. Since type is Meta_1's parent class (type being the default parent metaclass) and considering the ordering sequence of the output above, we now have a clue as to what would be the pseudo implementation of type.__call__():

class type:
    def __call__(cls, *args, **kwarg):

        # ... maybe a few things done to cls here

        # then we call __new__() on the class to create an instance
        instance = cls.__new__(cls, *args, **kwargs)

        # ... maybe a few things done to the instance here

        # then we initialize the instance with its __init__() method
        instance.__init__(*args, **kwargs)

        # ... maybe a few more things done to instance here

        # then we return it
        return instance

We can see that the metaclass' __call__() method is the one that's called first. It then delegates creation of the instance to the class's __new__() method and initialization to the instance's __init__(). It's also the one that ultimately returns the instance.

From the above it stems that the metaclass' __call__() is also given the opportunity to decide whether or not a call to Class_1.__new__() or Class_1.__init__() will eventually be made. Over the course of its execution it could actually return an object that hasn't been touched by either of these methods. Take for example this approach to the singleton pattern:

class Meta_2(type):
    singletons = {}

    def __call__(cls, *args, **kwargs):
        if cls in Meta_2.singletons:
            # we return the only instance and skip a call to __new__()
            # and __init__()
            print ("{} singleton returning from Meta_2.__call__(), "
                   "skipping creation of new instance.".format(cls))
            return Meta_2.singletons[cls]

        # else if the singleton isn't present we proceed as usual
        print "Meta_2.__call__() before creating an instance."
        instance = super(Meta_2, cls).__call__(*args, **kwargs)
        Meta_2.singletons[cls] = instance
        print "Meta_2.__call__() returning new instance."
        return instance

class Class_2(object):

    __metaclass__ = Meta_2

    def __new__(cls, *args, **kwargs):
        print "Class_2.__new__() before creating instance."
        instance = super(Class_2, cls).__new__(cls)
        print "Class_2.__new__() returning instance."
        return instance

    def __init__(self, *args, **kwargs):
        print "entering Class_2.__init__() for initialization."
        super(Class_2, self).__init__()
        print "exiting Class_2.__init__()."

Let's observe what happens when repeatedly trying to create an object of type Class_2

a = Class_2()
# Meta_2.__call__() before creating an instance.
# Class_2.__new__() before creating instance.
# Class_2.__new__() returning instance.
# entering Class_2.__init__() for initialization.
# exiting Class_2.__init__().
# Meta_2.__call__() returning new instance.

b = Class_2()
# <class '__main__.Class_2'> singleton returning from Meta_2.__call__(), skipping creation of new instance.

c = Class_2()
# <class '__main__.Class_2'> singleton returning from Meta_2.__call__(), skipping creation of new instance.

a is b is c # True

According to https://bugzilla.mozilla.org/show_bug.cgi?id=592284, the pref network.http.connection-retry-timeout controls the amount of time in ms (Milliseconds !) to wait for success on the initial connection before beginning the second one. Setting it to 0 disables the parallel connection.

there is much easier solution:

- (UIImage *)tranlucentWithAlpha:(CGFloat)alpha
{
    UIGraphicsBeginImageContextWithOptions(self.size, NO, self.scale);
    [self drawAtPoint:CGPointZero blendMode:kCGBlendModeNormal alpha:alpha];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

You might want to run bash -v to see what's being sourced.

I would do the following instead of playing with symlinks:

RUN echo "source /usr/local/bin/virtualenvwrapper.sh" >> /etc/bash.bashrc

Here you go.

SELECT
   column1, 
   column2
FROM
   viewWhatever
WHERE
CASE 
    WHEN @locationType = 'location' AND account_location = @locationID THEN 1
    WHEN @locationType = 'area' AND xxx_location_area = @locationID THEN 1
    WHEN @locationType = 'division' AND xxx_location_division = @locationID THEN 1
    ELSE 0
END = 1

$userinput = "http://www.example.vn/";
//$url = urlencode($userinput);
$input = @file_get_contents($userinput) or die("Could not access file: $userinput");
$regexp = "<tagname\s[^>]*>(.*)<\/tagname>";
//==Example:
//$regexp = "<div\s[^>]*>(.*)<\/div>";

if(preg_match_all("/$regexp/siU", $input, $matches, PREG_SET_ORDER)) {
    foreach($matches as $match) {
        // $match[2] = link address 
        // $match[3] = link text
    }
}

Just use str - for example:

>>> str([])
'[]'

A compiler consists of two major blocks: the 'front end' and the 'back end'. The front end of a compiler analyzes the source code and builds some form of a 'intermediary representation' of said source code which is much easier to analyze by a machine algorithm than is the source code (i.e. whereas the source code e.g. C++ is designed to help the human programmer to write code, the intermediary form is designed to help simplify the algorithm that analyzes said intermediary form easier). The back end of a compiler takes the intermediary form and then converts it to a 'target language'.

Now, the target language for general-use compilers are assembler languages for various processors, but there's nothing to prohibit a compiler back end to produce code in some other language, for as long as said target language is (at least) as flexible as a general CPU assembler.

Now, as you can probably imagine, C is definitely as flexible as a CPU's assembler, such that a C++ to C compiler is really no problem to implement from a technical pov.

So you have: C++ ---frontEnd---> someIntermediaryForm ---backEnd---> C

You may want to check these guys out: http://www.edg.com/index.php?location=c_frontend (the above link is just informative for what can be done, they license their front ends for tens of thousands of dollars)

PS As far as i know, there is no such a C++ to C compiler by GNU, and this totally beats me (if i'm right about this). Because the C language is fairly small and it's internal mechanisms are fairly rudimentary, a C compiler requires something like one man-year work (i can tell you this first hand cause i wrote such a compiler myself may years ago, and it produces a [virtual] stack machine intermediary code), and being able to have a maintained, up-to-date C++ compiler while only having to write a C compiler once would be a great thing to have...

The windows equivalent to the diff command is the fc (File Comapre) command.

Here are the basic steps to do so:
1. Keep the two files in a folder (Example file1.html and file2.html)
2. Launch command prompt
3. Type fc file1Location file2Location

Have found a detailed tutorial on the same:

http://www.howtogeek.com/206123/how-to-use-fc-file-compare-from-the-windows-command-prompt/

As BalausC mentioned in a comment, you are probably looking for CSS (Cascading Style Sheets) not HTML attributes.

To position an element, a <table> in your case you want to use either padding or margins.

the difference between margins and paddings can be seen as the "box model":

Image from HTML Dog article on margins and padding http://www.htmldog.com/guides/cssbeginner/margins/.

I highly recommend the article above if you need to learn how to use CSS.

To move the table down and right I would use margins like so:

table{
    margin:25px 0 0 25px;
}

This is in shorthand so the margins are as follows:

margin: top right bottom left;

Several other answer give the solution using MAX. In some scenarios using an agregate function is either not possilbe, or not performant.

The alternative that I use a lot is to use a correlated sub-query in the join...

SELECT
   `userName`,
   `carPrice`
FROM `users`
LEFT JOIN `cars`
ON cars.id = (
  SELECT id FROM `cars` WHERE BelongsToUser = users.id ORDER BY carPrice DESC LIMIT 1
)
WHERE `id`='4'

Welcome your corrections and improvements!

You should put those files into the same directory with Dockerfile.

Super easy way to do this.

let text = "This is a colorful attributed string"
let attributedText = 
NSMutableAttributedString.getAttributedString(fromString: text)
attributedText.apply(color: .red, subString: "This")
//Apply yellow color on range
attributedText.apply(color: .yellow, onRange: NSMakeRange(5, 4))

For more detail click here; https://github.com/iOSTechHub/AttributedString

try this :

@Html.DropDownList("Sortby", new SelectListItem[] { new SelectListItem() 
{ Text = "Newest to Oldest", Value = "0" }, new SelectListItem() 
{ Text = "Oldest to Newest", Value = "1" }},
new { onchange = "document.location.href = '/ControllerName/ActionName?id=' + this.options[this.selectedIndex].value;" })

This approach works when you want to prevent a certain filter and all the following ones. It should work well if you eg. want to serve some content as static resources within your servlet container instead of letting your application logic (through a filter like GuiceFilter):

Map the folder with your static resource files to the default servlet. Create a servlet filter and put it before the GuiceFilter in your web.xml. In your created filter, you can separate between forwarding some requests to the GuiceFilter and others directly to the dispatcher. Example follows...

web.xml

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>/static/*</url-pattern>
</servlet-mapping>

<filter>
    <filter-name>StaticResourceFilter</filter-name>
    <filter-class>com.project.filter.StaticResourceFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>StaticResourceFilter</filter-name>
    <url-pattern>/static/*</url-pattern>
</filter-mapping>

<filter>
    <filter-name>guiceFilter</filter-name>
    <filter-class>com.google.inject.servlet.GuiceFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>guiceFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

StaticResourceFilter.class

public class StaticResourceFilter implements Filter {

    private final static Logger LOGGER = LoggerFactory.getLogger(StaticResourceFilter.class);

    private static final String RESOURCE_PATH = "/static/";
    @Override
    public void init(final FilterConfig filterConfig) throws ServletException {
        LOGGER.info("StaticResourceFilter initialized");
    }

    @Override
    public void doFilter(final ServletRequest request, final ServletResponse response,
                         final FilterChain chain) throws IOException, ServletException {

        String path = ((HttpServletRequest) request).getServletPath();
        if (path.toLowerCase().startsWith(RESOURCE_PATH)) {
            request.getRequestDispatcher(path).forward(request, response);
        } else {
            chain.doFilter(request, response);
        }
    }

    @Override
    public void destroy() {
        LOGGER.info("StaticResourceFilter destroyed");
    }
}

Unfortunately if you just want to skip a single step in the filter chain while keeping those that follows, this will not work.

From the Java Language Specification, section 15.9.5.1:

An anonymous class cannot have an explicitly declared constructor.

Sorry :(

EDIT: As an alternative, you can create some final local variables, and/or include an instance initializer in the anonymous class. For example:

public class Test {
    public static void main(String[] args) throws Exception {
        final int fakeConstructorArg = 10;

        Object a = new Object() {
            {
                System.out.println("arg = " + fakeConstructorArg);
            }
        };
    }
}

It's grotty, but it might just help you. Alternatively, use a proper nested class :)

To round down towards negative infinity, use:

rounded=Math.floor(number);

To round down towards zero (if the number can round to a 32-bit integer between -2147483648 and 2147483647), use:

rounded=number|0;

To round down towards zero (for any number), use:

if(number>0)rounded=Math.floor(number);else rounded=Math.ceil(number);

I would like to suggest this code I made to find if there is a change in a value, i being the new value and d being the old (although the order does not matter). For that matter, a change from value to null or vice versa is a change but from null to null is not (of course, from value to another value is a change but from value to the same it is not).

CREATE FUNCTION [dbo].[ufn_equal_with_nulls]
(
    @i sql_variant,
    @d sql_variant
)
RETURNS bit
AS
BEGIN
    DECLARE @in bit = 0, @dn bit = 0
    if @i is null set @in = 1
    if @d is null set @dn = 1

    if @in <> @dn
        return 0

    if @in = 1 and @dn = 1
        return 1

    if @in = 0 and @dn = 0 and @i = @d
        return 1

    return 0

END

To use this function, you can

declare @tmp table (a int, b int)
insert into @tmp values
(1,1),
(1,2),
(1,null),
(null,1),
(null,null)

---- in select ----
select *, [dbo].[ufn_equal_with_nulls](a,b) as [=] from @tmp

---- where equal ----
select *,'equal' as [Predicate] from @tmp where  [dbo].[ufn_equal_with_nulls](a,b) = 1

---- where not equal ----
select *,'not equal' as [Predicate] from @tmp where  [dbo].[ufn_equal_with_nulls](a,b) = 0

The results are:

---- in select ----
a   b   =
1   1   1
1   2   0
1   NULL    0
NULL    1   0
NULL    NULL    1

---- where equal ----
1   1   equal
NULL    NULL    equal

---- where not equal ----
1   2   not equal
1   NULL    not equal
NULL    1   not equal

The usage of sql_variant makes it compatible for variety of types

**Rails 4.X +**

As of Rails 4 you can't generate a migration to add a column to a table with a default value, The following steps add a new column to an existing table with default value true or false.

1. Run the migration from command line to add the new column

$ rails generate migration add_columnname_to_tablename columnname:boolean

The above command will add a new column in your table.

2. Set the new column value to TRUE/FALSE by editing the new migration file created.

class AddColumnnameToTablename < ActiveRecord::Migration
  def change
    add_column :table_name, :column_name, :boolean, default: false
  end
end

**3. To make the changes into your application database table, run the following command in terminal**

$ rake db:migrate

Also, make sure your branch is clean and there is nothing unstaged you can check with git status stash or commit the changes then run the comand

>>> list1 = [[], [], [], [], [], 'text', 'text2', [], 'moreText']
>>> list2 = [e for e in list1 if e]
>>> list2
['text', 'text2', 'moreText']

I couldn't find an off-the-shelf module that added this function, so I wrote one:

In Access, go to the Database Tools ribbon, in the Macro area click into Visual Basic. In the top left Project area, right click the name of your file and select Insert -> Module. In the module paste this:

Public Function Substring_Index(strWord As String, strDelim As String, intCount As Integer) As String

Substring_Index = delims

start = 0
test = ""

For i = 1 To intCount
    oldstart = start + 1
    start = InStr(oldstart, strWord, strDelim)
    Substring_Index = Mid(strWord, oldstart, start - oldstart)
Next i

End Function

Save the module as module1 (the default). You can now use statements like:

SELECT Substring_Index([fieldname],",",2) FROM table

- Another Update -

Since Twitter Bootstrap version 2.0 - which saw the removal of the .container-fluid class - it has not been possible to implement a two column fixed-fluid layout using just the bootstrap classes - however I have updated my answer to include some small CSS changes that can be made in your own CSS code that will make this possible

It is possible to implement a fixed-fluid structure using the CSS found below and slightly modified HTML code taken from the Twitter Bootstrap Scaffolding : layouts documentation page:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="fixed">  <!-- we want this div to be fixed width -->
            ...
        </div>
        <div class="hero-unit filler">  <!-- we have removed spanX class -->
            ...
        </div>
    </div>
</div>

CSS

I have kept the answer below - even though the edit to support 2.0 made it a fluid-fluid solution - as it explains the concepts behind making the sidebar and content the same height (a significant part of the askers question as identified in the comments)

Important

Answer below is fluid-fluid

Update As pointed out by @JasonCapriotti in the comments, the original answer to this question (created for v1.0) did not work in Bootstrap 2.0. For this reason, I have updated the answer to support Bootstrap 2.0

To ensure that the main content fills at least 100% of the screen height, we need to set the height of the html and body to 100% and create a new css class called .fill which has a minimum-height of 100%:

html, body {
    height: 100%;
}

.fill { 
    min-height: 100%;
}

We can then add the .fill class to any element that we need to take up 100% of the sceen height. In this case we add it to the first div:

<div class="container-fluid fill">
    ...
</div>

To ensure that the Sidebar and the Content columns have the same height is very difficult and unnecessary. Instead we can use the ::after pseudo selector to add a filler element that will give the illusion that the two columns have the same height:

.filler::after {
    background-color: inherit;
    bottom: 0;
    content: "";
    right: 0;
    position: absolute;
    top: 0;
    width: inherit;
    z-index: -1;  
}

To make sure that the .filler element is positioned relatively to the .fill element we need to add position: relative to .fill:

.fill { 
    min-height: 100%;
    position: relative;
}

And finally add the .filler style to the HTML:

HTML

<div class="container-fluid fill">
    <div class="row-fluid">
        <div class="span3">
            ...
        </div>
        <div class="span9 hero-unit filler">
            ...
        </div>
    </div>
</div>

Notes

• If you need the element on the left of the page to be the filler then you need to change right: 0 to left: 0.

You can use the UNION ALL function http://blog.sqlauthority.com/2007/06/08/sql-server-insert-multiple-records-using-one-insert-statement-use-of-union-all/

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

Below code will look for last used row in sheet1 and copy the entire range from A1 upto last used row in column A to Sheet2 at exact same location.

Sub test()

    Dim lastRow As Long
    lastRow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
    Sheets("Sheet2").Range("A1:A" & lastRow).Value = Sheets("Sheet1").Range("A1:A" & lastRow).Value

End Sub

If you need to get the tab index from outside the context of a tabs event, use this:

function getSelectedTabIndex() { 
    return $("#TabList").tabs('option', 'selected');
}

Update: From version 1.9 'selected' is changed to 'active'

$("#TabList").tabs('option', 'active')

Make sure you have installed 'make' tool through Cygwin's installer.

Simple and crisp and works with almost all use cases (for API level 16 and above):

1. Use the following tag in your app theme to make the status bar transparent:

   <item name="android:statusBarColor">@android:color/transparent</item>

2. And then use this code in your activity's onCreate method.

   View decorView = getWindow().getDecorView();
   decorView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE
           | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
   

That's all you need to do ;)

You can learn more from the developer documentation. I'd also recommend reading this blog post.

KOTLIN CODE:

    val decorView = window.decorView
    decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN)

Check my another answer here

Vava's answer is on the mark. If you use jQuery, then the $.each() function takes care of this, hence it is safer to use.

$.each(evtListeners, function(index, elem) {
    // your code
});

The "break" command does not work within an "if" statement.

If you remove the "break" command from your code and then test the code, you should find that the code works exactly the same without a "break" command as with one.

"Break" is designed for use inside loops (for, while, do-while, enhanced for and switch).

To disable resizing completely:

textarea {
    resize: none;
}

To allow only vertical resizing:

textarea {
    resize: vertical;
}

To allow only horizontal resizing:

textarea {
    resize: horizontal;
}

Or you can limit size:

textarea {
    max-width: 100px; 
    max-height: 100px;
}

To limit size to parents width and/or height:

textarea {
    max-width: 100%; 
    max-height: 100%;
}

Use Object#toString().

String string = map.toString();

That's after all also what System.out.println(object) does under the hoods. The format for maps is described in AbstractMap#toString().

Returns a string representation of this map. The string representation consists of a list of key-value mappings in the order returned by the map's entrySet view's iterator, enclosed in braces ("{}"). Adjacent mappings are separated by the characters ", " (comma and space). Each key-value mapping is rendered as the key followed by an equals sign ("=") followed by the associated value. Keys and values are converted to strings as by String.valueOf(Object).

First Activity Code :

Intent mIntent = new Intent(ActivityA.this, ActivityB.class);
mIntent.putExtra("easyPuzzle", easyPuzzle);

Second Activity Code :

String easyPuzzle = getIntent().getStringExtra("easyPuzzle");

Very easy trick is using a CSS calc formula. All modern browsers, IE9, wide range of mobile browsers should support this.

<div style='white-space:nowrap'>
  <span style='display:inline-block;width:80px;font-weight:bold'>
    <label for='field1'>Field1</label>
  </span>
  <input id='field1' name='field1' type='text' value='Some text' size='30' style='width:calc(100% - 80px)' />
</div>

If you want to list last 3 chars, simplest way is

 select substr('123456',-3) from dual;

The standard Web Storage, does not say anything about the restoring any of these. So there won't be any standard way to do it. You have to go through the way the browsers implement these, or find a way to backup these before you delete them.

Place the following in the CODE MODULE of a WORKSHEET to track the last value for every cell in the used range:

Option Explicit

Private r As Range
Private Const d = "||"

Public Function ValueLast(r As Range)
    On Error Resume Next
    ValueLast = Split(r.ID, d)(1)
End Function

Private Sub Worksheet_Activate()
    For Each r In Me.UsedRange: Record r: Next
End Sub

Private Sub Worksheet_Change(ByVal Target As Range)
    For Each r In Target: Record r: Next
End Sub

Private Sub Record(r)
    r.ID = r.Value & d & Split(r.ID, d)(0)
End Sub

And that's it.

This solution uses the obscure and almost never used Range.ID property, which allows the old values to persist when the workbook is saved and closed.

At any time you can get at the old value of a cell and it will indeed be different than a new current value:

With Sheet1
    MsgBox .[a1].Value
    MsgBox .ValueLast(.[a1])
End With

I am not sure,how you are opening popup or say model in your code. But you can try something like this..

Instead of accepting a self parameter, class methods take a cls parameter that points to the class—and not the object instance—when the method is called. Since the class method only has access to this cls argument, it can’t modify object instance state. That would require access to self . However, class methods can still modify class state that applies across all instances of the class.

-Python Tricks

Assuming that your search is stylus photo 2100. Try the following example is using RLIKE.

SELECT * FROM `buckets` WHERE `bucketname` RLIKE REPLACE('stylus photo 2100', ' ', '+.*');

EDIT

Another way is to use FULLTEXT index on bucketname and MATCH ... AGAINST syntax in your SELECT statement. So to re-write the above example...

SELECT * FROM `buckets` WHERE MATCH(`bucketname`) AGAINST (REPLACE('stylus photo 2100', ' ', ','));

Make a class with pure virtual methods. Use the interface by creating another class that overrides those virtual methods.

A pure virtual method is a class method that is defined as virtual and assigned to 0.

class IDemo
{
    public:
        virtual ~IDemo() {}
        virtual void OverrideMe() = 0;
};

class Child : public IDemo
{
    public:
        virtual void OverrideMe()
        {
            //do stuff
        }
};

Store your results in variables, and use them in your HTML and add the necessary styling.

$usercity = $ip['cityName'];
$usercountry = $ip['countryName'];

And in the HTML, you could do:

<div id="userdetails">
<p> User's IP: <?php echo $usercity; ?> </p>
<p> Country: <?php echo $usercountry; ?> </p>
</div>

Now, you can simply add the styles for country class in your CSS, like so:

#userdetails {

/* styles go here */

}

Alternatively, you could also use this in your HTML:

<p style="font-size:15px; font-color: green;"><?php echo $userip; ?> </p>
<p style="font-size:15px; font-color: green;"><?php echo $usercountry; ?> </p>

Hope this helps!

for future visitors, you can add this functon that allow user to enter only numbers: you will only have to add jquery and the class name to the input check that into http://jsfiddle.net/celia/dvnL9has/2/

$('.phone_number').keypress(function(event){
var numero= String.fromCharCode(event.keyCode);
 var myArray = ['0','1','2','3','4','5','6','7','8','9',0,1,2,3,4,5,6,7,8,9];
index = myArray.indexOf(numero);// 1
var longeur= $('.phone_number').val().length;
if(window.getSelection){
 text = window.getSelection().toString();
 } if(index>=0&text.length>0){
  }else if(index>=0&longeur<10){
    }else {return false;} });

I love Ediff. It comes built-in with GNU Emacs.

To do a three-way diff, use ediff-files3 (for selecting three files) or ediff-buffer3 (for selecting three already-open buffers). You'll get a screen looking like this:

Note the word-difference higlighting.

You can hit n or p to go to the next/previous diffs, while ab will copy the region from buffer a (the leftmost one) to buffer b (the middle one), and similarly for other two-letter combinations of a, b, c; rb will restore the region in buffer b. Hit ? for a quick help menu, or read the fine manual on diff3 merging in Emacs.

Today the most obvious approach is to save the object(s) to JSON.

1. JSON is readable
2. JSON is more readable and easier to work with than XML.
3. A lot of Non-SQL databases that allow storing JSON directly.
4. Your client already communicates with the server using JSON. (If it doesn't, it is very likely a mistake.)

Example using Gson.

Gson gson = new Gson();
Person[] persons = getArrayOfPersons();
String json = gson.toJson(persons);
System.out.println(json);
//output: [{"name":"Tom","age":11},{"name":"Jack","age":12}]
Person[] personsFromJson = gson.fromJson(json, Person[].class);
//...
class Person {
     public String name;
     public int age;
} 

Gson allows converting List directly. Examples can be easily googled. I prefer to convert lists to arrays first.

To find the number of days in a month, DateTime class provides a method "DaysInMonth(int year, int month)". This method returns the total number of days in a specified month.

public int TotalNumberOfDaysInMonth(int year, int month)
    {
        return DateTime.DaysInMonth(year, month);
    }

OR

int days = DateTime.DaysInMonth(2018,05);

Output :- 31

A naive, CPU-intensive method to block execution for a number of milliseconds:

/**
* Delay for a number of milliseconds
*/
function sleep(delay) {
    var start = new Date().getTime();
    while (new Date().getTime() < start + delay);
}

Fixed my problem with this command in centos 7.6 Server

chcon -R -t httpd_sys_content_t $SITE_PATH

chcon -R -t httpd_sys_rw_content_t $SITE_PATH

This will use less memory, since it doesn't load the whole file into memory:

$file="largefile.txt";
$linecount = 0;
$handle = fopen($file, "r");
while(!feof($handle)){
  $line = fgets($handle);
  $linecount++;
}

fclose($handle);

echo $linecount;

fgets loads a single line into memory (if the second argument $length is omitted it will keep reading from the stream until it reaches the end of the line, which is what we want). This is still unlikely to be as quick as using something other than PHP, if you care about wall time as well as memory usage.

The only danger with this is if any lines are particularly long (what if you encounter a 2GB file without line breaks?). In which case you're better off doing slurping it in in chunks, and counting end-of-line characters:

$file="largefile.txt";
$linecount = 0;
$handle = fopen($file, "r");
while(!feof($handle)){
  $line = fgets($handle, 4096);
  $linecount = $linecount + substr_count($line, PHP_EOL);
}

fclose($handle);

echo $linecount;

I had a similar issue where the SelectedItem never got updated.

My problem was that the selected item was not the same instance as the item contained in the list. So I simply had to override the Equals() method in my MyCustomObject and compare the IDs of those two instances to tell the ComboBox that it's the same object.

public override bool Equals(object obj)
{
    return this.Id == (obj as MyCustomObject).Id;
}

Apache Commons Lang

DateUtils.isSameDay(date1, date2)

http://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/time/DateUtils.html#isSameDay(java.util.Date, java.util.Date)

From: http://developer.android.com/guide/topics/ui/notifiers/notifications.html

To clear the status bar notification when the user selects it from the Notifications window, add the "FLAG_AUTO_CANCEL" flag to your Notification object. You can also clear it manually with cancel(int), passing it the notification ID, or clear all your Notifications with cancelAll().

But Donal is right, you can only clear notifications that you created.

It's method syntax (which I find easier to read) but this might do it

Updated post comment

Use .FirstOrDefault() instead of .First()

With regard to the dates average, you may have to drop that ordering for the moment as I am unable to get to an IDE at the moment

var groupByReference = context.Measurements
                              .GroupBy(m => m.Reference)
                              .Select(g => new {Creation = g.FirstOrDefault().CreationTime, 
//                                              Avg = g.Average(m => m.CreationTime.Ticks),
                                                Items = g })
                              .OrderBy(x => x.Creation)
//                            .ThenBy(x => x.Avg)
                              .Take(numOfEntries)

It is possible in css, but not for all the browsers.

The effect on all browsers:

A possibility is a custom checkbox with javascript:

You are correct, but note that you can do it the other way around - use Android Wifi tethering that sets up the phone as a base station and connect to said base station from the laptop.

One another source of the issue with collations is mysql.proc table. Check collations of your storage procedures and functions:

SELECT
  p.db, p.db_collation, p.type, COUNT(*) cnt
FROM mysql.proc p
GROUP BY p.db, p.db_collation, p.type;

Also pay attention to mysql.proc.collation_connection and mysql.proc.character_set_client columns.

There's also the function tags, a bit more flexible:

<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn" %>
<c:if test="${fn:length(list) > 0}">

And here's the tag documentation.

Based on the above post concerning the ScheduledThreadPoolExecutor, I came up with a utility that suited my needs (wanted to fire a method every 3 seconds):

class MyActivity {
    private ScheduledThreadPoolExecutor mDialogDaemon;

    private void initDebugButtons() {
        Button btnSpawnDialogs = (Button)findViewById(R.id.btn_spawn_dialogs);
        btnSpawnDialogs.setVisibility(View.VISIBLE);
        btnSpawnDialogs.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View view) {
                spawnDialogs();
            }
        });
    }

    private void spawnDialogs() {
        if (mDialogDaemon != null) {
            mDialogDaemon.shutdown();
            mDialogDaemon = null;
        }
        mDialogDaemon = new ScheduledThreadPoolExecutor(1);
        // This process will execute immediately, then execute every 3 seconds.
        mDialogDaemon.scheduleAtFixedRate(new Runnable() {
            @Override
            public void run() {
                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        // Do something worthwhile
                    }
                });
            }
        }, 0L, 3000L, TimeUnit.MILLISECONDS);
    }
}

To use am / pm with moment, here is a snippet from a react component

import Moment from 'moment';

const time = Moment().format("hh:mm a")

For reference please remember Moment.js is considered a legacy project that can carry performance overhead

Traps and interrupts are closely related. Traps are a type of exception, and exceptions are similar to interrupts.

Intel x86 defines two overlapping categories, vectored events (interrupts vs exceptions), and exception classes (faults vs traps vs aborts).

All of the quotes in this post are from the April 2016 version of the Intel Software Developer Manual. For the (definitive and complex) x86 perspective, I recommend reading the SDM's chapter on Interrupt and Exception handling.

Vectored Events

Vectored Events (interrupts and exceptions) cause the processor to jump into an interrupt handler after saving much of the processor's state (enough such that execution can continue from that point later).

Exceptions and interrupts have an ID, called a vector, that determines which interrupt handler the processor jumps to. Interrupt handlers are described within the Interrupt Descriptor Table.

Interrupts

Interrupts occur at random times during the execution of a program, in response to signals from hardware. System hardware uses interrupts to handle events external to the processor, such as requests to service peripheral devices. Software can also generate interrupts by executing the INT n instruction.

Exceptions

Exceptions occur when the processor detects an error condition while executing an instruction, such as division by zero. The processor detects a variety of error conditions including protection violations, page faults, and internal machine faults.

Exception Classifications

Exceptions are classified as faults, traps, or aborts depending on the way they are reported and whether the instruction that caused the exception can be restarted without loss of program or task continuity.

Summary: traps increment the instruction pointer, faults do not, and aborts 'explode'.

Trap

A trap is an exception that is reported immediately following the execution of the trapping instruction. Traps allow execution of a program or task to be continued without loss of program continuity. The return address for the trap handler points to the instruction to be executed after the trapping instruction.

Fault

A fault is an exception that can generally be corrected and that, once corrected, allows the program to be restarted with no loss of continuity. When a fault is reported, the processor restores the machine state to the state prior to the beginning of execution of the faulting instruction. The return address (saved contents of the CS and EIP registers) for the fault handler points to the faulting instruction, rather than to the instruction following the faulting instruction.

Example: A page fault is often recoverable. A piece of an application's address space may have been swapped out to disk from ram. The application will trigger a page fault when it tries to access memory that was swapped out. The kernel can pull that memory from disk to ram, and hand control back to the application. The application will continue where it left off (at the faulting instruction that was accessing swapped out memory), but this time the memory access should succeed without faulting.

An illegal-instruction fault handler that emulates floating-point or other missing instructions would have to manually increment the return address to get the trap-like behaviour it needs, after seeing if the faulting instruction was one it could handle. x86 #UD is a "fault", not a "trap". (The handler would need a pointer to the faulting instruction to figure out which instruction it was.)

Abort

An abort is an exception that does not always report the precise location of the instruction causing the exception and does not allow a restart of the program or task that caused the exception. Aborts are used to report severe errors, such as hardware errors and inconsistent or illegal values in system tables.

Edge Cases

Software invoked interrupts (triggered by the INT instruction) behave in a trap-like manner. The instruction completes before the processor saves its state and jumps to the interrupt handler.

In CI v3, you can try:

function partial_uri($start = 0) {
    return join('/',array_slice(get_instance()->uri->segment_array(), $start));
}

This will drop the number of URL segments specified by the $start argument. If your URL is http://localhost/dropbox/derrek/shopredux/ahahaha/hihihi, then:

partial_uri(3);  # returns "ahahaha/hihihi"

Selenium has so many options to perform drag and drop.

In Action class we have couple of method which will perform the same task.

I have listed the possible solution please have a look.

your id attribute is not set. this MAY be due to the fact that the DB field is not set to auto increment? what DB are you using? MySQL? is your field set to AUTO INCREMENT?

Default arguments must be specified with the first occurrence of the function name—typically, in the function prototype. If the function prototype is omitted because the function definition also serves as the prototype, then the default arguments should be specified in the function header.

Solved for me by running a docker desktop app, check-in notification. Setup if necessary.

$ net start com.docker.service

The Docker for Windows Service service is starting. The Docker for Windows Service service was started successfully.

$ docker version

$ net start com.docker.service

The requested service has already been started.

There's no built in Stopwatch utility but as of JSR-310 (Java 8 Time) you can do this simply.

ZonedDateTime now = ZonedDateTime.now();
// Do stuff
long seconds = now.until(ZonedDateTime.now(), ChronoUnit.SECONDS);

I haven't benchmarked this properly but I would guess using Guava's Stopwatch is more effective.

I created this Function after researching on the internet since I wanted to print an XML string when you select a row from a data grid view.

static void HighlightPhrase(RichTextBox box, string StartTag, string EndTag, string ControlTag, Color color1, Color color2)
{
    int pos = box.SelectionStart;
    string s = box.Text;
    for (int ix = 0; ; )
    {
        int jx = s.IndexOf(StartTag, ix, StringComparison.CurrentCultureIgnoreCase);
        if (jx < 0) break;
        int ex = s.IndexOf(EndTag, ix, StringComparison.CurrentCultureIgnoreCase);
        box.SelectionStart = jx;
        box.SelectionLength = ex - jx + 1;
        box.SelectionColor = color1;
        
        int bx = s.IndexOf(ControlTag, ix, StringComparison.CurrentCultureIgnoreCase);
        int bxtest = s.IndexOf(StartTag, (ex + 1), StringComparison.CurrentCultureIgnoreCase);
        if (bx == bxtest)
        {
            box.SelectionStart = ex + 1;
            box.SelectionLength = bx - ex + 1;
            box.SelectionColor = color2;
        }
        
        ix = ex + 1;
    }
    box.SelectionStart = pos;
    box.SelectionLength = 0;
}

and this is how you call it

   HighlightPhrase(richTextBox1, "<", ">","</", Color.Red, Color.Black);

It looks like you're missing a return false.

problem is that the collapse item (div) is nested in the table elements. The div is hidden, the tr and td of the table are still visible and some css-styles are applied to them (border and padding).
Why are you using tables? Is there a reason for? When you dont´t have to use them, dont´use them :-)

For multidimensional arrays you can use the axis keyword in order to apply the partitioning along the expected axis.

# For a 2D array
indices = np.argpartition(arr, -N, axis=1)[:, -N:]

And for grabbing the items:

x = arr.shape[0]
arr[np.repeat(np.arange(x), N), indices.ravel()].reshape(x, N)

But note that this won't return a sorted result. In that case you can use np.argsort() along the intended axis:

indices = np.argsort(arr, axis=1)[:, -N:]

# Result
x = arr.shape[0]
arr[np.repeat(np.arange(x), N), indices.ravel()].reshape(x, N)

Here is an example:

In [42]: a = np.random.randint(0, 20, (10, 10))

VS2010 has a property for 'Build Action', and also for 'Copy to Output Directory'. So an action of 'None' will still copy over to the build directory if the copy property is set to 'Copy if Newer' or 'Copy Always'.

So a Build Action of 'Content' should be reserved to indicate content you will access via 'Application.GetContentStream'

I used the 'Build Action' setting of 'None' and the 'Copy to Output Direcotry' setting of 'Copy if Newer' for some externally linked .config includes.

Another solution in Linux:

string a = "?";
cout << "? = \xd0\xa4 = " << hex
     << int(static_cast<unsigned char>(a[0]))
     << int(static_cast<unsigned char>(a[1])) << " (" << a.length() << "B)" << endl;

string b = "v";
cout << "v = \xe2\x88\x9a = " << hex
     << int(static_cast<unsigned char>(b[0]))
     << int(static_cast<unsigned char>(b[1]))
     << int(static_cast<unsigned char>(b[2])) << " (" << b.length() << "B)" << endl;

To convert an Array[Row] to DataFrame or Dataset, the following works elegantly:

Say, schema is the StructType for the row,then

val rows: Array[Row]=...
implicit val encoder = RowEncoder.apply(schema)
import spark.implicits._
rows.toDS

Make the destructor virtual whenever your class is polymorphic.

in the graphical layout, you can choose the theme on the toolbar. (the one that looks like a star).

choose the NoTitleBar and have fun.

Assuming you have:

HashMap<Key, Value> map; // Assigned or populated somehow.

For a list of values:

List<Value> values = new ArrayList<Value>(map.values());

For a list of keys:

List<Key> keys = new ArrayList<Key>(map.keySet());

Note that the order of the keys and values will be unreliable with a HashMap; use a LinkedHashMap if you need to preserve one-to-one correspondence of key and value positions in their respective lists.

Noted that for DatePicker by Keith Wood (http://keith-wood.name/datepickRef.html) the following works - note that the setting of the default date is last:

    $('#datepicker').datepick({
        minDate: 0,
        maxDate: '+145D',
        multiSelect: 7,
        renderer: $.datepick.themeRollerRenderer,
        ***defaultDate: new Date('1 January 2008')***
    });

For me, it worked best to add this in image css: max-width:100%; and NOT specify image width and height in html parameters. This adjusted the width to fit in device screen while adjusting height automatically. Otherwise height might be distorted.

and if nothing helps and you still want to present that website in an iframe consider using X Frame Bypass Component which will utilize a proxy.

ViewBag is a dynamic type that allow you to dynamically set or get values and allow you to add any number of additional fields without a strongly-typed class They allow you to pass data from controller to view. In controller......

public ActionResult Index()
{
    ViewBag.victor = "My name is Victor";
    return View();
}

In view

@foreach(string a in ViewBag.victor)
{
     .........
}

What I have learnt is that both should have the save dynamic name property ie ViewBag.victor

Firstly, I believe that trying to do several things at once is a bad practice in general and I suggest you think over what you are trying to achieve.

It serves as a good theoretical question though and from what I gather the CopyOnWriteArraySet implementation of java.util.Set interface satisfies your rather special requirements.

http://download.oracle.com/javase/1,5.0/docs/api/java/util/concurrent/CopyOnWriteArraySet.html

DESCRIBE DATABASE NAME; you need to specify the name of the database and the results will include the data type of each attribute.

To summarize:

import ast, yaml, json, timeit

        %timeit func(string)        
    print('')

Results:

*** short string ***

json loads:

yaml load:
504 µs ± 1.29 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

*** long string ***

json loads:
29.6 µs ± 230 ns per loop (mean ± std. dev. of 7 runs, 10000 loops each)

Conclusion: prefer json.loads

Becomes more difficult when you need year and week.
Try to find out which week is 01.01.2017.
(It is the 52nd week of 2016, which is from Mon 26.12.2016 - Sun 01.01.2017).

After a longer search I found

strftime('%G-%V',strtotime("2017-01-01"))

Result: 2016-52

https://www.php.net/manual/de/function.strftime.php
ISO-8601:1988 week number of the given year, starting with the first week of the year with at least 4 weekdays, with Monday being the start of the week. (01 through 53)

The equivalent in mysql is DATE_FORMAT(date, '%x-%v') https://www.w3schools.com/sql/func_mysql_date_format.asp
Week where Monday is the first day of the week (01 to 53).

Could not find a corresponding solution with date() or DateTime.
At least not without solutions like "+1day, last monday".

Every method in Web API will return data (JSON) without serialization.

However, in order to return JSON Data in MVC controllers, we will set the returned Action Result type to JsonResult and call the Json method on our object to ensure it is packaged in JSON.

Something like this should work, I'm not sure whether or not there is a simpler way:

@RequestMapping(value = "/matches/{matchId}", produces = "application/json")
@ResponseBody
public String match(@PathVariable String matchId, @RequestBody String body,
            HttpServletRequest request, HttpServletResponse response) {
    String json = matchService.getMatchJson(matchId);
    if (json == null) {
        response.setStatus( HttpServletResponse.SC_BAD_REQUEST  );
    }
    return json;
}

Nowadays, Java 8 allows for a one-line functional solution that is cleaner, faster, and a whole lot simpler than the accepted solution:

List<String> list = new ArrayList<>();
list.add("behold");
list.add("bend");
list.add("bet");
list.add("bear");
list.add("beat");
list.add("become");
list.add("begin");

List<String> matches = list.stream().filter(it -> it.contains("bea")).collect(Collectors.toList());

System.out.println(matches); // [bear, beat]

And even easier in Kotlin:

val matches = list.filter { it.contains("bea") }

I believe that if you want to specify a color as a resource (in the XML file), you'll have to provide its ARGB value (not simply the RGB value).

Try changing your color value to #FFFF0000. It should give you RED.

try this

SELECT CONVERT(DECIMAL(10,2),YOURCOLUMN)

I have just met this problem today: I migrated my Excel project from Office 2007 to 2010. At a certain point, when my macro tried to Insert a new line (e.g. Range("5:5").Insert ), the same error message came. It happens only when previously another sheet has been edited (my macro switches to another sheet).

Thanks to Google, and your discussion, I found the following solution (based on the answer given by "red" at answered Jul 30 '13 at 0:27): after switching to the sheet a Cell has to be edited before inserting a new row. I have added the following code:

'=== Excel bugfix workaround - 2014.08.17
Range("B1").Activate
vCellValue = Range("B1").Value
Range("B1").ClearContents
Range("B1").Value = vCellValue

"B1" can be replaced by any cell on the sheet.

A raw-type is the a lack of a type parameter when using a generic type.

Raw-type should not be used because it could cause runtime errors, like inserting a double into what was supposed to be a Set of ints.

Set set = new HashSet();
set.add(3.45); //ok

When retrieving the stuff from the Set, you don't know what is coming out. Let's assume that you expect it to be all ints, you are casting it to Integer; exception at runtime when the double 3.45 comes along.

With a type parameter added to your Set, you will get a compile error at once. This preemptive error lets you fix the problem before something blows up during runtime (thus saving on time and effort).

Set<Integer> set = new HashSet<Integer>();
set.add(3.45); //NOT ok.

To subtract timevals:

gettimeofday(&t0, 0);
/* ... */
gettimeofday(&t1, 0);
long elapsed = (t1.tv_sec-t0.tv_sec)*1000000 + t1.tv_usec-t0.tv_usec;

This is assuming you'll be working with intervals shorter than ~2000 seconds, at which point the arithmetic may overflow depending on the types used. If you need to work with longer intervals just change the last line to:

long long elapsed = (t1.tv_sec-t0.tv_sec)*1000000LL + t1.tv_usec-t0.tv_usec;

Do something like this:

int showLimit = 20;

/* Get all Tasks available (with limit set). */
ActivityManager mgr = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningTaskInfo> allTasks = mgr.getRunningTasks(showLimit);
/* Loop through all tasks returned. */
for (ActivityManager.RunningTaskInfo aTask : allTasks) 
{                  
    Log.i("MyApp", "Task: " + aTask.baseActivity.getClassName()); 
    if (aTask.baseActivity.getClassName().equals("com.android.email.activity.MessageList")) 
        running=true;
}

Macbook: ?J or fnF1 does the same.
Also, use the one from the editor definition as explained above.

You can use the react-moment package

-> https://www.npmjs.com/package/react-moment

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

I am using the SVG using D3.js and i had the same issue.

I used this code for removing the previous svg but the linear gradient inside SVG were not coming in IE

$("#container_div_id").html("");

then I wrote the below code to resolve the issue

$('container_div_id g').remove();
$('#container_div_id path').remove();

here i am removing the previous g and path inside the SVG, replacing with the new one.

Keeping my linear gradient inside SVG tags in the static content and then I called the above code, This works in IE

List<String> strings = Arrays.asList(new String[]{"one", "two", "three"});

This is a list view of the array, the list is partly unmodifiable, you can't add or delete elements. But the time complexity is O(1).

If you want a modifiable a List:

List<String> strings = 
     new ArrayList<String>(Arrays.asList(new String[]{"one", "two", "three"}));

This will copy all elements from the source array into a new list (complexity: O(n))

Well, since you are using Python, you can just open a file and keep reading lines from it.

f = open('file.log')

If the line read is not empty, you process it.

line = f.readline()
if line:
    // Do what you want with the line

You may be missing that it is ok to keep calling readline at the EOF. It will just keep returning an empty string in this case. And when something is appended to the log file, the reading will continue from where it stopped, as you need.

If you are looking for a solution that uses events, or a particular library, please specify this in your question. Otherwise, I think this solution is just fine.

For IE8 support, the "content" property cannot be empty.

To get around this I've done the following :

.ul li:after {
    content:"icon";
    text-indent:-999em;
    display:block;
    width:32px;
    height:32px;
    background:url(../img/icons/spritesheet.png) 0 -620px no-repeat;
    margin:5% 0 0 45%;
}

Note : This works with image sprites too

Thanks for the idea of breaking down a formula Werner!

Using Alt+Enter allows one to put each bit of a complex substitute formula on separate lines: they become easier to follow and automatically line themselves up when Enter is pressed.

Just make sure you have enough end statements to match the number of substitute( lines either side of the cell reference.

As in this example:

=
substitute(
substitute(
substitute(
substitute(
B11
,"(","")
,")","")
,"[","")
,"]","")

becomes:

=
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(
SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

which works fine as is, but one can always delete the extra paragraphs manually:

=SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(SUBSTITUTE(B12,"(",""),")",""),"[",""),"]","")

Name > substitute()

[American Samoa] > American Samoa

I found another relatively easy solution for your question.

As you can see from the FragmentPagerAdapter source code, the fragments managed by FragmentPagerAdapter store in the FragmentManager under the tag generated using:

String tag="android:switcher:" + viewId + ":" + index;

The viewId is the container.getId(), the container is your ViewPager instance. The index is the position of the fragment. Hence you can save the object id to the outState:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    outState.putInt("viewpagerid" , mViewPager.getId() );
}

@Override
    protected void onCreate(Bundle savedInstanceState) {
    setContentView(R.layout.activity_main);
    if (savedInstanceState != null)
        viewpagerid=savedInstanceState.getInt("viewpagerid", -1 );  

    MyFragmentPagerAdapter titleAdapter = new MyFragmentPagerAdapter (getSupportFragmentManager() , this);        
    mViewPager = (ViewPager) findViewById(R.id.pager);
    if (viewpagerid != -1 ){
        mViewPager.setId(viewpagerid);
    }else{
        viewpagerid=mViewPager.getId();
    }
    mViewPager.setAdapter(titleAdapter);

If you want to communicate with this fragment, you can get if from FragmentManager, such as:

getSupportFragmentManager().findFragmentByTag("android:switcher:" + viewpagerid + ":0")

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

This method works with any Stream and is Java 8 compliant:

Stream<Integer> myStream = Stream.of(1, 2, 3, 4, 5);
myStream.reduce(Stream.empty(),
        (Stream<Integer> a, Integer b) -> Stream.concat(Stream.of(b), a),
        (a, b) -> Stream.concat(b, a))
        .forEach(System.out::println);

A quick and simple way would be :

var Colors = function(){
return {
    'WHITE':0,
    'BLACK':1,
    'RED':2,
    'GREEN':3
    }
}();

console.log(Colors.WHITE)  //this prints out "0"

Yes. Using the JsonConvert class which contains helper methods for this precise purpose:

// To convert an XML node contained in string xml into a JSON string   
XmlDocument doc = new XmlDocument();
doc.LoadXml(xml);
string jsonText = JsonConvert.SerializeXmlNode(doc);

// To convert JSON text contained in string json into an XML node
XmlDocument doc = JsonConvert.DeserializeXmlNode(json);

Documentation here: Converting between JSON and XML with Json.NET

Its very easy to implement . For that you need to create a one xml file(selector file) and put it in drawable folder in res. After that set xml file in button's background in your layout file.

button_background_selector.xml

<?xml version="1.0" encoding="UTF-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/your_hover_image" />
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/your_hover_image" />
    <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/your_hover_image"/>
    <item android:drawable="@drawable/your_simple_image" />
</selector>

Now set the above file in button's background.

<Button
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:textColor="@color/grey_text"
    android:background="@drawable/button_background_selector"/>

You are missing zlib.h header file, on Linux install it via:

sudo apt-get install libz-dev

As a matter of fact, the module presents as zlib1g-dev in the apt repo, so this is the up-to-date call (Feb 2019):

sudo apt install zlib1g-dev

On Fedora: sudo dnf install zlib-devel (in older versions: sudo dnf install libz-devel).

This will provide the development support files for a library implementing the deflate compression method found in gzip and PKZIP.

If you've already zlib library, make sure you're compiling your code sources with -lz. See: How to fix undefined references to inflate/deflate functions?.

A better way in long run is to integrate Gradle in your project environment. Its a build tool for Java, and now being used a lot in the android development space.

You will need to make a .gradle file and list your library dependencies. Then, all you would need to do is import the project in IntelliJ using Gradle.

Cheers

Notice that if the file's parent folder doesn't exist you'll get the same error:

IOError: [Errno 2] No such file or directory:

Below is another solution which handles this case:
(*) I used sys.stdout and print instead of f.write just to show another use case

# Make sure the file's folder exist - Create folder if doesn't exist
folder_path = 'path/to/'+folder_name+'/'
if not os.path.exists(folder_path):
     os.makedirs(folder_path)

print_to_log_file(folder_path, "Some File" ,"Some Content")

Where the internal print_to_log_file just take care of the file level:

# If you're not familiar with sys.stdout - just ignore it below (just a use case example)
def print_to_log_file(folder_path ,file_name ,content_to_write):

   #1) Save a reference to the original standard output       
    original_stdout = sys.stdout   
    
    #2) Choose the mode
    write_append_mode = 'a' #Append mode
    file_path = folder_path + file_name
    if (if not os.path.exists(file_path) ):
       write_append_mode = 'w' # Write mode
     
    #3) Perform action on file
    with open(file_path, write_append_mode) as f:
        sys.stdout = f  # Change the standard output to the file we created.
        print(file_path, content_to_write)
        sys.stdout = original_stdout  # Reset the standard output to its original value

Consider the following states:

'w'  --> Write to existing file
'w+' --> Write to file, Create it if doesn't exist
'a'  --> Append to file
'a+' --> Append to file, Create it if doesn't exist

In your case I would use a different approach and just use 'a' and 'a+'.

Here, I wrote something similar to what u need:

    inputBoxNumberEt.setText(".     ");
    inputBoxNumberEt.setSelection(inputBoxNumberEt.getText().length());
    inputBoxNumberEt.addTextChangedListener(new TextWatcher() {

        boolean ignoreChange = false;

        @Override
        public void afterTextChanged(Editable s) {
        }

        @Override
        public void beforeTextChanged(CharSequence s, int start,
                                      int count, int after) {
        }

        @Override
        public void onTextChanged(CharSequence s, int start,
                                  int before, int count) {
            if (!ignoreChange) {
                String string = s.toString();
                string = string.replace(".", "");
                string = string.replace(" ", "");
                if (string.length() == 0)
                    string = ".     ";
                else if (string.length() == 1)
                    string = ".  " + string;
                else if (string.length() == 2)
                    string = "." + string;
                else if (string.length() > 2)
                    string = string.substring(0, string.length() - 2) + "." + string.substring(string.length() - 2, string.length());
                ignoreChange = true;
                inputBoxNumberEt.setText(string);
                inputBoxNumberEt.setSelection(inputBoxNumberEt.getText().length());
                ignoreChange = false;
            }
        }
    });

So what is the URL that Yii::app()->params['pdfUrl'] gives? You say it should be https, but the log shows it's connecting on port 80... which almost no server is setup to accept https connections on. cURL is smart enough to know https should be on port 443... which would suggest that your URL has something wonky in it like: https://196.41.139.168:80/serve/?r=pdf/generatePdf

That's going to cause the connection to be terminated, when the Apache at the other end cannot do https communication with you on that port.

You realize your first $body definition gets replaced when you set $body to an array two lines later? {Probably just an artifact of you trying to solve the problem} You're also not encoding the client_url and client_id values (the former quite possibly containing characters that need escaping!) Oh and you're appending to $body_str without first initializing it.

From your verbose output we can see cURL is adding a content-length header, but... is it correct? I can see some comments out on the internets of that number being wrong (especially with older versions)... if that number was to small (for example) you'd get a connection-reset before all the data is sent. You can manually insert the header:

curl_setopt ($c, CURLOPT_HTTPHEADER, 
   array("Content-Length: ". strlen($body_str))); 

Oh and there's a handy function http_build_query that'll convert an array of name/value pairs into a URL encoded string for you.

All this rolls up into the final code:

$post=http_build_query(array(
  "client_url"=>Yii::app()->params['pdfClientURL'],
  "client_id"=>Yii::app()->params['pdfClientID'],
  "title"=>$title,
  "content"=>$content));

//Open to URL
$c=curl_init(Yii::app()->params['pdfUrl']);
//Send post
curl_setopt ($c, CURLOPT_POST, true);
//Optional: [try with/without]
curl_setopt ($c, CURLOPT_HTTPHEADER, array("Content-Length: ".strlen($post))); 
curl_setopt ($c, CURLOPT_POSTFIELDS, $post);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt ($c, CURLOPT_CONNECTTIMEOUT , 0);
curl_setopt ($c, CURLOPT_TIMEOUT  , 20);
//Collect result
$pdf = curl_exec ($c);
$curlInfo = curl_getinfo($c);
curl_close($c);

Replace

new Timestamp();

with

new java.util.Date()

because there is no default constructor for Timestamp, or you can do it with the method:

new Timestamp(System.currentTimeMillis());

SOLVED
After banging my head on the wall for a couple days with this issue, it was looking like the problem had something to do with the content type negotiation between the client and server. I dug deeper into that using Fiddler to check the request details coming from the client app, here's a screenshot of the raw request as captured by fiddler:

What's obviously missing there is the Content-Type header, even though I was setting it as seen in the code sample in my original post. I thought it was strange that the Content-Type never came through even though I was setting it, so I had another look at my other (working) code calling a different Web API service, the only difference was that I happened to be setting the req.ContentType property prior to writing to the request body in that case. I made that change to this new code and that did it, the Content-Type was now showing up and I got the expected success response from the web service. The new code from my .NET client now looks like this:

req.Method = "POST"
req.ContentType = "application/json"
lstrPagingJSON = JsonSerializer(Of Paging)(lPaging)
bytData = Encoding.UTF8.GetBytes(lstrPagingJSON)
req.ContentLength = bytData.Length
reqStream = req.GetRequestStream()
reqStream.Write(bytData, 0, bytData.Length)
reqStream.Close()
'// Content-Type was being set here, causing the problem
'req.ContentType = "application/json"

That's all it was, the ContentType property just needed to be set prior to writing to the request body

I believe this behavior is because once content is written to the body it is streamed to the service endpoint being called, any other attributes pertaining to the request need to be set prior to that. Please correct me if I'm wrong or if this needs more detail.

The other way to move introduced work from one branch to another is to cherry-pick it. A cherry-pick in Git is like a rebase for a single commit. It takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on. This is useful if you have a number of commits on a topic branch and you want to integrate only one of them, or if you only have one commit on a topic branch and you’d prefer to cherry-pick it rather than run rebase. For example, suppose you have a project that looks like this:

If you want to pull commit e43a6 into your master branch, you can run

$ git cherry-pick e43a6
Finished one cherry-pick.
[master]: created a0a41a9: "More friendly message when locking the index fails."
 3 files changed, 17 insertions(+), 3 deletions(-)

This pulls the same change introduced in e43a6, but you get a new commit SHA-1 value, because the date applied is different. Now your history looks like this:

Now you can remove your topic branch and drop the commits you didn’t want to pull in.

If origin points to a bare repository on disk, this error can happen if that directory has been moved (even if you update the working copy's remotes). For example

$ mv /path/to/origin /somewhere/else
$ git remote set-url origin /somewhere/else
$ git diff origin/master
fatal: ambiguous argument 'origin': unknown revision or path not in the working tree.

Pulling once from the new origin solves the problem:

$ git stash
$ git pull origin master
$ git stash pop

If you want to know the user version in your code, then you can use using app() helper function

app()->version();

It is defined in this file ../src/Illuminate/Foundation/Application.php

Hope it will help :)

'Input' => Illuminate\Support\Facades\Input::class, add it to App.php.

Adding on to Jonathan's answer, here are the events to cover the focus and active states, and a using onMouseOver instead of onMouseEnter since the latter will not bubble if you have any child elements within the target the event is being applied to.

var Link = React.createClass({

  getInitialState: function(){
    return {hover: false, active: false, focus: false}
  },

  toggleHover: function(){
    this.setState({hover: !this.state.hover})
  },

  toggleActive: function(){
    this.setState({active: !this.state.active})
  },

  toggleFocus: function(){
    this.setState({focus: !this.state.focus})
  },

  render: function() {
    var linkStyle;
    if (this.state.hover) {
      linkStyle = {backgroundColor: 'red'}
    } else if (this.state.active) {
      linkStyle = {backgroundColor: 'blue'}
    } else if (this.state.focus) {
      linkStyle = {backgroundColor: 'purple'}
    } 

    return(
      <div>
        <a style={linkStyle} 
          onMouseOver={this.toggleHover} 
          onMouseOut={this.toggleHover} 
          onMouseUp={this.toggleActive} 
          onMouseDown={this.toggleActive} 
          onFocus={this.toggleFocus}> 
          Link 
        </a>
      </div>
    )
  }

I have used like this to show the soft keyboard programatically and this is worked for me to prevent the auto resize of the screen while launching the keyboard.

In manifest:

<activity android:name="XXXActivity" android:windowSoftInputMode="adjustPan">
</activity>

In XXXActvity:

EditText et =  (EditText))findViewById(R.id.edit_text);  
  Timer timer = new Timer();
            TimerTask task = new TimerTask() {

                @Override
                public void run() {
                    InputMethodManager inputMethodManager=(InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    inputMethodManager.toggleSoftInputFromWindow(et.getApplicationWindowToken(), InputMethodManager.SHOW_FORCED, 0);

                }
            };
            timer.schedule(task, 200);

I assume this will save others time to search for this problem.

Try;

$data = json_decode(file_get_contents('php://input'), true);
print_r($data);
echo $data["operacion"];

From your json and your code, it looks like you have spelled the word operation correctly on your end, but it isn't in the json.

EDIT

Maybe also worth trying to echo the json string from php://input.

echo file_get_contents('php://input');
