I had similar problem, but the wrong setting was in the extern .lib file from which I did not have sources. If you do not have the source files, the simplest workaround is to just change the content of the .lib file.

Open the .lib file in an editor (I used PSPad, bud Windows notepad is also possible) and replace all occurences of _ITERATOR_DEBUG_LEVEL=2 to _ITERATOR_DEBUG_LEVEL=0

You need to adjust three (or four) properties:

• Consumer side:fetch.message.max.bytes - this will determine the largest size of a message that can be fetched by the consumer.
• Broker side: replica.fetch.max.bytes - this will allow for the replicas in the brokers to send messages within the cluster and make sure the messages are replicated correctly. If this is too small, then the message will never be replicated, and therefore, the consumer will never see the message because the message will never be committed (fully replicated).
• Broker side: message.max.bytes - this is the largest size of the message that can be received by the broker from a producer.
• Broker side (per topic): max.message.bytes - this is the largest size of the message the broker will allow to be appended to the topic. This size is validated pre-compression. (Defaults to broker's message.max.bytes.)

I found out the hard way about number 2 - you don't get ANY exceptions, messages, or warnings from Kafka, so be sure to consider this when you are sending large messages.

Try to explain this question in a level referring to a little bit technology

Take MongoDB and Traditional SQL for comparison, imagine the scenario of posting a Tweet on Twitter. This tweet contains 9 pictures. How do you store this tweet and its corresponding pictures?

In terms of traditional relationship SQL, you can store the tweets and pictures in separate tables, and represent the connection through building a new table.

What's more, you can set a field which is an image type, and zip the 9 pictures into a binary document and store it in this field.

Using MongoDB, you could build a document like this (similar to the concept of a table in relational SQL):

{

"id":"XXX",

"user":"XXX",

"date":"xxxx-xx-xx",

"content":{

"text":"XXXX",

"picture":["p1.png","p2.png","p3.png"]

}

Therefore, in my opinion, the main difference is about how do you store the data and the storage level of the relationships between them.

In this example, the data is the tweet and the pictures. The different mechanism about storage level of relationship between them also play a important role in the difference between both.

I hope this small example helps show the difference between SQL and NoSQL (ACID and BASE).

Here's a link of picture about the goals of NoSQL from the Internet:

http://icamchuwordpress-wordpress.stor.sinaapp.com/uploads/2015/01/dbc795f6f262e9d01fa0ab9b323b2dd1_b.png

Another cause of this could be if you don't use the default variable name for the "id" which is actually: id.

I just tested on Laravel Framework 5.7.19 and the following steps work:

Make sure your .babelrc file is in the root folder of your application, and add the following code:

{
  "plugins": ["@babel/plugin-proposal-class-properties"]
}

Run npm install --save-dev @babel/plugin-proposal-class-properties.

Run npm run watch.

Error code 2 means "File/Directory not found". In general, you could use the perror function to print a human readable string.

Watch this video, I had the same question. He shows you how to debug the service as well.

Here are his instructions using the basic C# Windows Service template in Visual Studio 2010/2012.

You add this to the Service1.cs file:

public void onDebug()
{
    OnStart(null);
}

You change your Main() to call your service this way if you are in the DEBUG Active Solution Configuration.

static void Main()
{
    #if DEBUG
    //While debugging this section is used.
    Service1 myService = new Service1();
    myService.onDebug();
    System.Threading.Thread.Sleep(System.Threading.Timeout.Infinite);

    #else
    //In Release this section is used. This is the "normal" way.
    ServiceBase[] ServicesToRun;
    ServicesToRun = new ServiceBase[] 
    { 
        new Service1() 
    };
    ServiceBase.Run(ServicesToRun);
    #endif
}

Keep in mind that while this is an awesome way to debug your service. It doesn't call OnStop() unless you explicitly call it similar to the way we called OnStart(null) in the onDebug() function.

This works for me:

plt.xticks(rotation=90)

var jsonIssues = [
 {ID:'1',Name:'Some name',Notes:'NOTES'},
 {ID:'2',Name:'Some name 2',Notes:'NOTES 2'}
];

If you want to add to the array then you can do this

jsonIssues[jsonIssues.length] = {ID:'3',Name:'Some name 3',Notes:'NOTES 3'};

Or you can use the push technique that the other guy posted, which is also good.

var mode = 0;
var c = 0;
var num = new Array();
var value = 0;
var greatest = 0;
var ct = 0;

Note: ct is the length of the array.

function getMode()
{
    for (var i = 0; i < ct; i++)
    {
        value = num[i];
        if (i != ct)
        {
            while (value == num[i + 1])
            {
                c = c + 1;
                i = i + 1;
            }
        }
        if (c > greatest)
        {
            greatest = c;
            mode = value;
        }
        c = 0;
    }
}

You need to set ulimit -c. If you have 0 for this parameter a coredump file is not created. So do this: ulimit -c unlimited and check if everything is correct ulimit -a. The coredump file is created when an application has done for example something inappropriate. The name of the file on my system is core.<process-pid-here>.

Quick google search says you can embed it like this:

But you need a different implementation in Internet Explorer.

http://www.websiteoptimization.com/speed/tweak/inline-images/

After trying to solve this issue for some time, I managed to come with a working solution that is also valid:

var event = new MouseEvent('mousedown');
element.dispatchEvent(event);

I've tried to implement this in Jquery as well, using trigger and mousedown or only mousedown but with no success.

What output (exactly) does dir myfile.txt give in the current directory? What happens if you set the delimiters?

FOR /f "tokens=1,2* delims= " %%a in ('dir myfile.txt^|find /i " myfile.txt"') DO SET fileDate=%%a 

(note the space after delims=)
(to make life easier, you can do this from the command line by replacing %%a with %a)

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

SO what I change is I load upload library each time

                $config = array();
                $config['upload_path'] = $filePath;
                $config['allowed_types'] = 'gif|jpg|png';
                $config['max_size']      = '0';
                $config['overwrite']     = FALSE;

                $files = $_FILES;
                $count = count($_FILES['nameUpload']['name']);


                for($i=0; $i<$count; $i++)
                {
                    $this->load->library('upload', $config);

                    $_FILES['nameUpload']['name']= $files['nameUpload']['name'][$i];
                    $_FILES['nameUpload']['type']= $files['nameUpload']['type'][$i];
                    $_FILES['nameUpload']['tmp_name']= $files['nameUpload']['tmp_name'][$i];
                    $_FILES['nameUpload']['error']= $files['nameUpload']['error'][$i];
                    $_FILES['nameUpload']['size']= $files['nameUpload']['size'][$i];

                    $this->upload->do_upload('nameUpload');
                }

And it work for me.

Make sure that you don't declare it as a integer, float, string or boolean before. http://php.net/manual/en/function.is-scalar.php

Edit the SSH configuration

nano ~/.ssh/config

    Host company.gitlab.com
    HostName gitlab.com

Here is the source that I used.

If you are using RESTful resources you can do the following:

redirect_to action_name_resource_path(resource_object, param_1: 'value_1', param_2: 'value_2')

or
#You can also use the object_id instead of the object
redirect_to action_name_resource_path(resource_object_id, param_1: 'value_1', param_2: 'value_2')

or
#if its a collection action like index, you can omit the id as follows
redirect_to action_name_resource_path(param_1: 'value_1', param_2: 'value_2')

#An example with nested resource is as follows:
redirect_to edit_user_project_path(@user, @project, param_1: 'value_1', param_2: 'value_2')

To verify only first letter is number or character -- For number Character.isDigit(str.charAt(0)) --return true

For character Character.isLetter(str.charAt(0)) --return true

Here is a CSV action result I wrote that takes a DataTable and converts it into CSV. You can return this from your view and it will prompt the user to download the file. You should be able to convert this easily into a List compatible form or even just put your list into a DataTable.

The answer by Leos Literak is correct but now outdated, using one of the troublesome old date-time classes, java.sql.Timestamp.

tl;dr

it is really a DATETIME in the DB

Nope, it is not. No such data type as DATETIME in Oracle database.

I was looking for a getDateTime method.

Use java.time classes in JDBC 4.2 and later rather than troublesome legacy classes seen in your Question. In particular, rather than java.sql.TIMESTAMP, use Instant class for a moment such as the SQL-standard type TIMESTAMP WITH TIME ZONE.

Contrived code snippet:

if( 
    JDBCType.valueOf( 
        myResultSetMetaData.getColumnType( … )
    )
    .equals( JDBCType.TIMESTAMP_WITH_TIMEZONE ) 
) {
    Instant instant = myResultSet.getObject( … , Instant.class ) ;
}

Oddly enough, the JDBC 4.2 specification does not require support for the two most commonly used java.time classes, Instant and ZonedDateTime. So if your JDBC does not support the code seen above, use OffsetDateTime instead.

OffsetDateTime offsetDateTime = myResultSet.getObject( … , OffsetDateTime.class ) ;

Details

I would like to get the DATETIME column from an Oracle DB Table with JDBC.

According to this doc, there is no column data type DATETIME in the Oracle database. That terminology seems to be Oracle’s word to refer to all their date-time types as a group.

I do not see the point of your code that detects the type and branches on which data-type. Generally, I think you should be crafting your code explicitly in the context of your particular table and particular business problem. Perhaps this would be useful in some kind of generic framework. If you insist, read on to learn about various types, and to learn about the extremely useful new java.time classes built into Java 8 and later that supplant the classes used in your Question.

Smart objects, not dumb strings

valueToInsert = aDate.toString();

You appear to trying to exchange date-time values with your database as text, as String objects. Don’t.

To exchange date-time values with your database, use date-time objects. Now in Java 8 and later, that means java.time objects, as discussed below.

Various type systems

You may be confusing three sets of date-time related data types:

• Standard SQL types
• Proprietary types
• JDBC types

SQL standard types

The SQL standard defines five types:

• DATE
• TIME WITHOUT TIME ZONE
• TIME WITH TIME ZONE
• TIMESTAMP WITHOUT TIME ZONE
• TIMESTAMP WITH TIME ZONE

Date-only

• DATE
  Date only, no time, no time zone.

Time-Of-Day-only

• TIME or TIME WITHOUT TIME ZONE
  Time only, no date. Silently ignores any time zone specified as part of input.
• TIME WITH TIME ZONE (or TIMETZ)
  Time only, no date. Applies time zone and Daylight Saving Time rules if sufficient data is included with input. Of questionable usefulness given the other data types, as discussed in Postgres doc.

Date And Time-Of-Day

• TIMESTAMP or TIMESTAMP WITHOUT TIME ZONE
  Date and time, but ignores time zone. Any time zone information passed to the database is ignores with no adjustment to UTC. So this does not represent a specific moment on the timeline, but rather a range of possible moments over about 26-27 hours. Use this if the time zone or offset are (a) unknown or (b) irrelevant such as "All our factories around the world close at noon for lunch". If you have any doubts, not likely the right type.
• TIMESTAMP WITH TIME ZONE (or TIMESTAMPTZ)
  Date and time with respect for time zone. Note that this name is something of a misnomer depending on the implementation. Some systems may store the given time zone info. In other systems such as Postgres the time zone information is not stored, instead the time zone information passed to the database is used to adjust the date-time to UTC.

Proprietary

Many database offer their own date-time related types. The proprietary types vary widely. Some are old, legacy types that should be avoided. Some are believed by the vendor to offer certain benefits; you decide whether to stick with the standard types only or not. Beware: Some proprietary types have a name conflicting with a standard type; I’m looking at you Oracle DATE.

JDBC

The Java platform's handles the internal details of date-time differently than does the SQL standard or specific databases. The job of a JDBC driver is to mediate between these differences, to act as a bridge, translating the types and their actual implemented data values as needed. The java.sql.* package is that bridge.

JDBC legacy classes

Prior to Java 8, the JDBC spec defined 3 types for date-time work. The first two are hacks as before Version 8, Java lacked any classes to represent a date-only or time-only value.

• java.sql.Date
  Simulates a date-only, pretends to have no time, no time zone. Can be confusing as this class is a wrapper around java.util.Date which tracks both date and time. Internally, the time portion is set to zero (midnight UTC).
• java.sql.Time
  Time only, pretends to have no date, and no time zone. Can also be confusing as this class too is a thin wrapper around java.util.Date which tracks both date and time. Internally, the date is set to zero (January 1, 1970).
• java.sql.TimeStamp
  Date and time, but no time zone. This too is a thin wrapper around java.util.Date.

So that answers your question regarding no "getDateTime" method in the ResultSet interface. That interface offers getter methods for the three bridging data types defined in JDBC:

• getDate for java.sql.Date
• getTime for java.sql.Time
• getTimestamp for java.sql.Timestamp

Note that the first lack any concept of time zone or offset-from-UTC. The last one, java.sql.Timestamp is always in UTC despite what its toString method tells you.

JDBC modern classes

You should avoid those poorly-designed JDBC classes listed above. They are supplanted by the java.time types.

• Instead of java.sql.Date, use LocalDate. Suits SQL-standard DATE type.
• Instead of java.sql.Time, use LocalTime. Suits SQL-standard TIME WITHOUT TIME ZONE type.
• Instead of java.sql.Timestamp, use Instant. Suits SQL-standard TIMESTAMP WITH TIME ZONE type.

As of JDBC 4.2 and later, you can directly exchange java.time objects with your database. Use setObject/getObject methods.

Insert/update.

myPreparedStatement.setObject( … , instant ) ;

Retrieval.

Instant instant = myResultSet.getObject( … , Instant.class ) ;

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

If you want to see the moment of an Instant as viewed through the wall-clock time used by the people of a particular region (a time zone) rather than as UTC, adjust by applying a ZoneId to get a ZonedDateTime object.

ZoneId zAuckland = ZoneId.of( "Pacific/Auckland" ) ;
ZonedDateTime zdtAuckland = instant.atZone( zAuckland ) ;

The resulting ZonedDateTime object is the same moment, the same simultaneous point on the timeline. A new day dawns earlier to the east, so the date and time-of-day will differ. For example, a few minutes after midnight in New Zealand is still “yesterday” in UTC.

You can apply yet another time zone to either the Instant or ZonedDateTime to see the same simultaneous moment through yet another wall-clock time used by people in some other region.

ZoneId zMontréal = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdtMontréal = zdtAuckland.withZoneSameInstant( zMontréal ) ;  // Or, for the same effect: instant.atZone( zMontréal ) 

So now we have three objects (instant, zdtAuckland, zMontréal) all representing the same moment, same point on the timeline.

Detecting type

To get back to the code in Question about detecting the data-type of the databases: (a) not my field of expertise, (b) I would avoid this as mentioned up top, and (c) if you insist on this, beware that as of Java 8 and later, the java.sql.Types class is outmoded. That class is now replaced by a proper Java Enum of JDBCType that implements the new interface SQLType. See this Answer to a related Question.

This change is listed in JDBC Maintenance Release 4.2, sections 3 & 4. To quote:

Addition of the java.sql.JDBCType Enum

An Enum used to identify generic SQL Types, called JDBC Types. The intent is to use JDBCType in place of the constants defined in Types.java.

The enum has the same values as the old class, but now provides type-safety.

A note about syntax: In modern Java, you can use a switch on an Enum object. So no need to use cascading if-then statements as seen in your Question. The one catch is that the enum object’s name must be used unqualified when switching for some obscure technical reason, so you must do your switch on TIMESTAMP_WITH_TIMEZONE rather than the qualified JDBCType.TIMESTAMP_WITH_TIMEZONE. Use a static import statement.

So, all that is to say that I guess (I’ve not tried yet) you can do something like the following code example.

final int columnType = myResultSetMetaData.getColumnType( … ) ;
final JDBCType jdbcType = JDBCType.valueOf( columnType ) ;

switch( jdbcType ) {  

    case DATE :  // FYI: Qualified type name `JDBCType.DATE` not allowed in a switch, because of an obscure technical issue. Use a `static import` statement.
        …
        break ;

    case TIMESTAMP_WITH_TIMEZONE :
        …
        break ;

    default :
        … 
        break ;

}

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

UPDATE: The Joda-Time project, now in maintenance mode, advises migration to the java.time classes. This section left intact as history.

Joda-Time

Prior to Java 8 (java.time.* package), the date-time classes bundled with java (java.util.Date & Calendar, java.text.SimpleDateFormat) are notoriously troublesome, confusing, and flawed.

A better practice is to take what your JDBC driver gives you and from that create Joda-Time objects, or in Java 8, java.time.* package. Eventually, you should see new JDBC drivers that automatically use the new java.time.* classes. Until then some methods have been added to classes such as java.sql.Timestamp to interject with java.time such as toInstant and fromInstant.

String

As for the latter part of the question, rendering a String… A formatter object should be used to generate a string value.

The old-fashioned way is with java.text.SimpleDateFormat. Not recommended.

Joda-Time provide various built-in formatters, and you may also define your own. But for writing logs or reports as you mentioned, the best choice may be ISO 8601 format. That format happens to be the default used by Joda-Time and java.time.

Example Code

//java.sql.Timestamp timestamp = resultSet.getTimestamp(i);
// Or, fake it 
// long m = DateTime.now().getMillis();
// java.sql.Timestamp timestamp = new java.sql.Timestamp( m );

//DateTime dateTimeUtc = new DateTime( timestamp.getTime(), DateTimeZone.UTC );
DateTime dateTimeUtc = new DateTime( DateTimeZone.UTC ); // Defaults to now, this moment.

// Convert as needed for presentation to user in local time zone.
DateTimeZone timeZone = DateTimeZone.forID("Europe/Paris");
DateTime dateTimeZoned = dateTimeUtc.toDateTime( timeZone );

Dump to console…

System.out.println( "dateTimeUtc: " + dateTimeUtc );
System.out.println( "dateTimeZoned: " + dateTimeZoned );

When run…

dateTimeUtc: 2014-01-16T22:48:46.840Z
dateTimeZoned: 2014-01-16T23:48:46.840+01:00

If you are using impdp command example from @sathyajith-bhat response:

impdp <username>/<password> directory=<directoryname> dumpfile=<filename>.dmp logfile=<filename>.log full=y;

you will need to use mandatory parameter directory and create and grant it as:

CREATE OR REPLACE DIRECTORY DMP_DIR AS 'c:\Users\USER\Downloads';
GRANT READ, WRITE ON DIRECTORY DMP_DIR TO {USER};

or use one of defined:

select * from DBA_DIRECTORIES;

My ORACLE Express 11g R2 has default named DATA_PUMP_DIR (located at {inst_dir}\app\oracle/admin/xe/dpdump/) you sill need to grant it for your user.

For selecting all in visual: Type Esc to be sure yor are in normal mode

With Ansible 2.x you can use vars: with tasks.

Template test.j2:

mkdir -p {{myTemplateVariable}}

Playbook:

- template: src=test.j2 dest=/tmp/File1
  vars:
    myTemplateVariable: myDirName

- template: src=test.j2 dest=/tmp/File2
  vars:
    myTemplateVariable: myOtherDir

This will pass different myTemplateVariable values into test.j2.

Adapt-Strap. Here is the fiddle.

It is extremely lightweight and has dynamic row heights.

<ad-table-lite table-name="carsForSale"
               column-definition="carsTableColumnDefinition"
               local-data-source="models.carsForSale"
               page-sizes="[7, 20]">
</ad-table-lite>

Same result you can achieve using the Splitter class.

var list = Splitter.on(",").splitToList(YourStringVariable)

(written in kotlin)

use: $anchorScroll();

with $anchorScroll property

It's calling the files included in that particular bundle which is declared inside the BundleConfig class in the App_Start folder.

In that particular case The call to @Styles.Render("~/Content/css") is calling "~/Content/site.css".

bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css"));

this error messages means that CABundle is not given by (-CAfile ...) OR the CABundle file is not closed by a self-signed root certificate.

Don't worry. The connection to server will work even you get theis message from openssl s_client ... (assumed you dont take other mistake too)

Go to /xampp/mysql/bin and find for mysql. exe

OuterClass.this references the outer class.

There are two widely-used memory allocation techniques: automatic allocation and dynamic allocation. Commonly, there is a corresponding region of memory for each: the stack and the heap.

Stack

The stack always allocates memory in a sequential fashion. It can do so because it requires you to release the memory in the reverse order (First-In, Last-Out: FILO). This is the memory allocation technique for local variables in many programming languages. It is very, very fast because it requires minimal bookkeeping and the next address to allocate is implicit.

In C++, this is called automatic storage because the storage is claimed automatically at the end of scope. As soon as execution of current code block (delimited using {}) is completed, memory for all variables in that block is automatically collected. This is also the moment where destructors are invoked to clean up resources.

Heap

The heap allows for a more flexible memory allocation mode. Bookkeeping is more complex and allocation is slower. Because there is no implicit release point, you must release the memory manually, using delete or delete[] (free in C). However, the absence of an implicit release point is the key to the heap's flexibility.

Reasons to use dynamic allocation

Even if using the heap is slower and potentially leads to memory leaks or memory fragmentation, there are perfectly good use cases for dynamic allocation, as it's less limited.

Two key reasons to use dynamic allocation:

• You don't know how much memory you need at compile time. For instance, when reading a text file into a string, you usually don't know what size the file has, so you can't decide how much memory to allocate until you run the program.

• You want to allocate memory which will persist after leaving the current block. For instance, you may want to write a function string readfile(string path) that returns the contents of a file. In this case, even if the stack could hold the entire file contents, you could not return from a function and keep the allocated memory block.

Why dynamic allocation is often unnecessary

In C++ there's a neat construct called a destructor. This mechanism allows you to manage resources by aligning the lifetime of the resource with the lifetime of a variable. This technique is called RAII and is the distinguishing point of C++. It "wraps" resources into objects. std::string is a perfect example. This snippet:

int main ( int argc, char* argv[] )
{
    std::string program(argv[0]);
}

actually allocates a variable amount of memory. The std::string object allocates memory using the heap and releases it in its destructor. In this case, you did not need to manually manage any resources and still got the benefits of dynamic memory allocation.

In particular, it implies that in this snippet:

int main ( int argc, char* argv[] )
{
    std::string * program = new std::string(argv[0]);  // Bad!
    delete program;
}

there is unneeded dynamic memory allocation. The program requires more typing (!) and introduces the risk of forgetting to deallocate the memory. It does this with no apparent benefit.

Why you should use automatic storage as often as possible

Basically, the last paragraph sums it up. Using automatic storage as often as possible makes your programs:

• faster to type;
• faster when run;
• less prone to memory/resource leaks.

Bonus points

In the referenced question, there are additional concerns. In particular, the following class:

class Line {
public:
    Line();
    ~Line();
    std::string* mString;
};

Line::Line() {
    mString = new std::string("foo_bar");
}

Line::~Line() {
    delete mString;
}

Is actually a lot more risky to use than the following one:

class Line {
public:
    Line();
    std::string mString;
};

Line::Line() {
    mString = "foo_bar";
    // note: there is a cleaner way to write this.
}

The reason is that std::string properly defines a copy constructor. Consider the following program:

int main ()
{
    Line l1;
    Line l2 = l1;
}

Using the original version, this program will likely crash, as it uses delete on the same string twice. Using the modified version, each Line instance will own its own string instance, each with its own memory and both will be released at the end of the program.

Other notes

Extensive use of RAII is considered a best practice in C++ because of all the reasons above. However, there is an additional benefit which is not immediately obvious. Basically, it's better than the sum of its parts. The whole mechanism composes. It scales.

If you use the Line class as a building block:

 class Table
 {
      Line borders[4];
 };

Then

 int main ()
 {
     Table table;
 }

allocates four std::string instances, four Line instances, one Table instance and all the string's contents and everything is freed automagically.

Douglas Crockford has a converter, but I'm not sure it will help with bad JSON to good JSON.

https://github.com/douglascrockford/JSON-js

The key takeaway is to check the .err file, by default on Mac OSX it's in /usr/local/var/mysql.

That log filed revealed to me that I had to delete the following files:

ibdata1
ib_logfile0
ib_logfile1

Running MySQL with mysql.start worked successfully after that. Note that deleting those files will likely causes data loss.

i get the solution. i've using cygwin and this is the problem the rsync command for Windows work only in windows shell and works in the windows powershell.

A few times it has happened the same error between two linux boxes. and appears to be by incompatible versions of rsync

Just call getArguments() in your Frag2's onCreateView() method:

public class Frag2 extends Fragment {

     public View onCreateView(LayoutInflater inflater,
         ViewGroup containerObject,
         Bundle savedInstanceState){
         //here is your arguments
         Bundle bundle=getArguments(); 

        //here is your list array 
        String[] myStrings=bundle.getStringArray("elist");   
     }
}

Use XmlTextWriter...

public static string PrintXML(string xml)
{
    string result = "";

    MemoryStream mStream = new MemoryStream();
    XmlTextWriter writer = new XmlTextWriter(mStream, Encoding.Unicode);
    XmlDocument document = new XmlDocument();

    try
    {
        // Load the XmlDocument with the XML.
        document.LoadXml(xml);

        writer.Formatting = Formatting.Indented;

        // Write the XML into a formatting XmlTextWriter
        document.WriteContentTo(writer);
        writer.Flush();
        mStream.Flush();

        // Have to rewind the MemoryStream in order to read
        // its contents.
        mStream.Position = 0;

        // Read MemoryStream contents into a StreamReader.
        StreamReader sReader = new StreamReader(mStream);

        // Extract the text from the StreamReader.
        string formattedXml = sReader.ReadToEnd();

        result = formattedXml;
    }
    catch (XmlException)
    {
        // Handle the exception
    }

    mStream.Close();
    writer.Close();

    return result;
}

data.substring(0, input.length) === input

You must be providing the wrong path to the debug.keystore file.

Follow these steps to get the correct path and complete your command:

1. In eclipse, click the Window menu -> Preferences -> Expand Android -> Build
2. In the right panel, look for: Default debug keystore:
3. Select the entire box next to the label specified in Step 2

And finally, use the path you just copied from Step 3 to construct your command:

For example, in my case, it would be:

C:\Program Files\Java\jre7\bin>keytool -list -v -keystore "C:\Users\Siddharth Lele.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

UPDATED:

If you had already followed the steps mentioned above, the only other solution is to delete the debug.keystore and let Eclipse recreate it for you.

Step 1: Go to the path where your keystore is stored. In your case, C:\Users\Suresh\.android\debug.keystore

Step 2: Close and restart Eclipse.

Step 3 (Optional): You may need to clean your project before the debug.keystore is created again.

Source: http://www.coderanch.com/t/440920/Security/KeyTool-genkeypair-exception-Keystore-file

You can refer to this for the part about deleting your debug.keystore file: "Debug certificate expired" error in Eclipse Android plugins

public static <T> List<T> toList(String json, Class<T> clazz) {
    if (null == json) {
        return null;
    }
    Gson gson = new Gson();
    return gson.fromJson(json, new TypeToken<T>(){}.getType());
}

sample call:

List<Specifications> objects = GsonUtils.toList(products, Specifications.class);

With one feature my Dataframe list converts to a Series. I had to convert it back to a Dataframe list and it worked.

if type(X) is Series:
    X = X.to_frame()

One more thing, if you want to change the navigation bg color in UIPopover you need to set barStyle to UIBarStyleBlack

if([UINavigationBar instancesRespondToSelector:@selector(barTintColor)]){ //iOS7
    navigationController.navigationBar.barStyle = UIBarStyleBlack;
    navigationController.navigationBar.barTintColor = [UIColor redColor];
}

Easy way to send array params to web api

API

public IEnumerable<Category> GetCategories([FromUri]int[] categoryIds){
 // code to retrieve categories from database
}

Jquery : send JSON object as request params

$.get('api/categories/GetCategories',{categoryIds:[1,2,3,4]}).done(function(response){
console.log(response);
//success response
});

It will generate your request URL like ../api/categories/GetCategories?categoryIds=1&categoryIds=2&categoryIds=3&categoryIds=4

This is the snippet to store environment variable and access it.

node {
   withEnv(["ENABLE_TESTS=true", "DISABLE_SQL=false"]) {
      stage('Select Jenkinsfile') {
          echo "Enable test?: ${env.DEVOPS_SKIP_TESTS}
          customStep script: this
      }
   }
}

Note: The value of environment variable is coming as a String. If you want to use it as a boolean then you have to parse it using Boolean.parse(env.DISABLE_SQL).

The code is

document.addEventListener('keydown', function(event){
    alert(event.keyCode);
} );

This return the ascii code of the key. If you need the key representation, use event.key (This will return 'a', 'o', 'Alt'...)

I can't add a comment above as I do not have enough reputation, but the above answer was nearly perfect for me, except I had to add

type: "POST"

to the .ajax call. I was scratching my head for a few minutes trying to figure out what I had done wrong, that's all it needed and works a treat. So this is the whole snippet:

Full credit to the answer above me, this is just a small tweak to that. This is just in case anyone else gets stuck and can't see the obvious.

  $.ajax({
    url: 'Your url here',
    data: formData,
    type: "POST", //ADDED THIS LINE
    // THIS MUST BE DONE FOR FILE UPLOADING
    contentType: false,
    processData: false,
    // ... Other options like success and etc
})

This issue appeared to me in android studio 2.0 stable channel and the solution was due to a problem happened while updating my android studio i solved this by installing a fresh android studio. after deleting all old files for the old installation. and to keep the very nice feature of Instant Run

Reason for the error:

Column tries to expands in vertical axis, and so does the ListView, hence you need to constrain the height of ListView.

Solutions

1. Use either Expanded or Flexible if you want to allow ListView to take up entire left space in Column.

   Column(
     children: <Widget>[
       Expanded(
         child: ListView(...),
       )
     ],
   )
   

2. Use SizedBox if you want to restrict the size of ListView to a certain height.

   Column(
     children: <Widget>[
       SizedBox(
         height: 200, // constrain height
         child: ListView(),
       )
     ],
   )
   

3. Use shrinkWrap, if your ListView isn't too big.

   Column(
     children: <Widget>[
       ListView(
         shrinkWrap: true, // use it
       )
     ],
   )
   

The most similar method to readdir is probably using the little-known _find family of functions.

Just use TreeMap

new TreeMap<String, String>(unsortMap);

Be aware that the TreeMap is sorted according to the natural ordering of its 'keys'

The clean way to do so is to pass a new instance of the created entity through the controller:

//GET
public ActionResult CreateNewMyEntity(string default_value)
{
    MyEntity newMyEntity = new MyEntity();
    newMyEntity._propertyValue = default_value;

    return View(newMyEntity);
}

If you want to pass the default value through ActionLink

@Html.ActionLink("Create New", "CreateNewMyEntity", new { default_value = "5" })

You can use this in your MySQL WHERE clause to return records that were created within the last 7 days/week:

created >= DATE_SUB(CURDATE(),INTERVAL 7 day)

Also use NOW() in the subtraction to give hh:mm:ss resolution. So to return records created exactly (to the second) within the last 24hrs, you could do:

created >= DATE_SUB(NOW(),INTERVAL 1 day)

I met this problem today, and fix it with bellowed steps.

1, Check the log file /var/log/mysqld.log

tail -f /var/log/mysqld.log

 2017-03-14T07:06:53.374603Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 2 - No such file or directory)
 2017-03-14T07:06:53.374614Z 0 [ERROR] Can't start server: can't create PID file: No such file or directory

The log says that there isn't a file or directory /var/run/mysqld/mysqld.pid

2, Create the directory /var/run/mysqld

mkdir -p /var/run/mysqld/

3, Start the mysqld again service mysqld start, but still fail, check the log again /var/log/mysqld.log

2017-03-14T07:14:22.967667Z 0 [ERROR] /usr/sbin/mysqld: Can't create/write to file '/var/run/mysqld/mysqld.pid' (Errcode: 13 - Permission denied)
2017-03-14T07:14:22.967678Z 0 [ERROR] Can't start server: can't create PID file: Permission denied

It saids permission denied.

4, Grant the permission to mysql chown mysql.mysql /var/run/mysqld/

5, Restart the mysqld

# service mysqld restart
Restarting mysqld (via systemctl):                         [  OK  ]

To get rid of the trailing zeros, you should use the "%g" format:

float num = 1.33;
printf("%g", num); //output: 1.33

After the question was clarified a bit, that suppressing zeros is not the only thing that was asked, but limiting the output to three decimal places was required as well. I think that can't be done with sprintf format strings alone. As Pax Diablo pointed out, string manipulation would be required.

following will show one table of dataset

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = ds; // dataset
DataGridView1.DataMember = "TableName"; // table name you need to show

if you want to show multiple tables, you need to create one datatable or custom object collection out of all tables.

if two tables with same table schema

dtAll = dtOne.Copy(); // dtOne = ds.Tables[0]
dtAll.Merge(dtTwo); // dtTwo = dtOne = ds.Tables[1]

DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ; // datatable

sample code to mode all tables

DataTable dtAll = ds.Tables[0].Copy();
for (var i = 1; i < ds.Tables.Count; i++)
{
     dtAll.Merge(ds.Tables[i]);
}
DataGridView1.AutoGenerateColumns = true;
DataGridView1.DataSource = dtAll ;

Every Driver service in selenium calls the similar code(following is the firefox specific code) while creating the driver object

 @Override
 protected File findDefaultExecutable() {
      return findExecutable(
        "geckodriver", GECKO_DRIVER_EXE_PROPERTY,
        "https://github.com/mozilla/geckodriver",
        "https://github.com/mozilla/geckodriver/releases");
    }

now for the driver that you want to use, you have to set the system property with the value of path to the driver executable.

for firefox GECKO_DRIVER_EXE_PROPERTY = "webdriver.gecko.driver" and this can be set before creating the driver object as below

System.setProperty("webdriver.gecko.driver", "./libs/geckodriver.exe");
WebDriver driver = new FirefoxDriver();

It's a pretty general concept, so code examples are not going to give the whole picture.

One guy here at work said to me, "patterns are like fractals, you can see them when you zoom in really close, and when you zoom way out to the architecture level."

Reading the brief wikipedia page can give you a sense of this generalness:

http://en.wikipedia.org/wiki/Loose_coupling

As far as a specific code example...

Here's one loose coupling I've worked with recently, from the Microsoft.Practices.CompositeUI stuff.

    [ServiceDependency]
    public ICustomizableGridService CustomizableGridService
    {
        protected get { return _customizableGridService; }
        set { _customizableGridService = value; }
    }

This code is declaring that this class has a dependency on a CustomizableGridService. Instead of just directly referencing the exact implementation of the service, it simply states that it requires SOME implementation of that service. Then at runtime, the system resolves that dependency.

If that's not clear, you can read a more detailed explanation here:

http://en.wikipedia.org/wiki/Dependency_injection

Imagine that ABCCustomizableGridService is the imlpementation I intend to hook up here.

If I choose to, I can yank that out and replace it with XYZCustomizableGridService, or StubCustomizableGridService with no change at all to the class with this dependency.

If I had directly referenced ABCCustomizableGridService, then I would need to make changes to that/those reference/s in order to swap in another service implementation.

you can use position:relative; inside #one div and position:absolute inside #two div. you can see it

When you have 'NA' values in the column, then

sum(as.numeric(JuneData1$Account.Balance), na.rm = TRUE)

library(matrixStats)
> data <- rbind(c("M", "F", "M"), c("Student", "Analyst", "Analyst"))
> rowCounts(data, value = 'M') # output = 2 0
> rowCounts(data, value = 'F') # output = 1 0

In SQL Plus:

VAR rc REFCURSOR
EXEC gokul_proc(1,'GOKUL', :rc);
print rc

You can set the fontsize directly in the call to set_xticklabels and set_yticklabels (as noted in previous answers). This will only affect one Axes at a time.

ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

You can also set the ticklabel font size globally (i.e. for all figures/subplots in a script) using rcParams:

import matplotlib.pyplot as plt

plt.rc('xtick',labelsize=8)
plt.rc('ytick',labelsize=8)

Or, equivalently:

plt.rcParams['xtick.labelsize']=8
plt.rcParams['ytick.labelsize']=8

Finally, if this is a setting that you would like to be set for all your matplotlib plots, you could also set these two rcParams in your matplotlibrc file:

xtick.labelsize      : 8 # fontsize of the x tick labels
ytick.labelsize      : 8 # fontsize of the y tick labels

The below change works seamlessly.

Quoting from CrazyPenguin's reply

"For those, like me, who found that even on the new Eclipse it wasn't scaled, see here: swt-autoscale-tweaks Basically I added -Dswt.autoScale=quarter to my eclipse.ini file."

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

You need to provide a valid strict weak ordering comparison for the type stored in the queue, Person in this case. The default is to use std::less<T>, which resolves to something equivalent to operator<. This relies on it's own stored type having one. So if you were to implement

bool operator<(const Person& lhs, const Person& rhs); 

it should work without any further changes. The implementation could be

bool operator<(const Person& lhs, const Person& rhs)
{
  return lhs.age < rhs.age;
}

If the the type does not have a natural "less than" comparison, it would make more sense to provide your own predicate, instead of the default std::less<Person>. For example,

struct LessThanByAge
{
  bool operator()(const Person& lhs, const Person& rhs) const
  {
    return lhs.age < rhs.age;
  }
};

then instantiate the queue like this:

std::priority_queue<Person, std::vector<Person>, LessThanByAge> pq;

Concerning the use of std::greater<Person> as comparator, this would use the equivalent of operator> and have the effect of creating a queue with the priority inverted WRT the default case. It would require the presence of an operator> that can operate on two Person instances.

2019 update

You can now discard unstaged changes in one tracked file with:

git restore <file>

and in all tracked files in the current directory (recursively) with:

git restore .

If you run the latter from the root of the repo, it will discard unstaged changes in all tracked files.

Notes

• git restore was introduced in July 2019 and released in version 2.23 as part of a split of the git checkout command into git restore for files and git switch for branches.
• git checkout still behaves as it used to and the older answers remain perfectly valid.
• When running git status with unstaged changes in the working tree, this is now what Git suggests to use to discard them (instead of git checkout -- <file> as it used to prior to v2.23).
• As with git checkout -- ., this only discards changes in tracked files. So Mariusz Nowak's answer still applies and if you want to discard all unstaged changes, including untracked files, you could run, as he suggests, an additional git clean -df.

A quick way is to use python command line tool. Simply type import <your module name> You see an error if module is missing.

$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
>>> import sys
>>> import jocker
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named jocker
$

In case anyone still needs the VBA way of doing this:

The properties, assuming you selected something, are:

With Selection
    .interior.pattern = xlNone
    .Borders(xl<side>).Linestyle = xlNone
End Selection

Where <side> can be for example DiagonalDown or EdgeTop, so

-> Selection.Borders(xlEdgeTop).Linestyle = xlNone

would reset the Top Edge.

Hmm... i do it in one of my batch files like this, without using CALL or START :

Updated for Swift 3 and above:

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

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

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

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

Swift 2.x

Assuming you want an action alert on iOS:

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

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

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

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

With Bootstrap you can use an anchor like a button.

<a class="btn btn-success" href="https://www.google.com" target="_blank">Google</a>

And use target="_blank" to open the link in a new tab.

If you'd like to display the full name (instead of the username), add the -F flag:

$ id -F
Andrew Havens

You might want to start with scapy.

 $Name= "'".$row['Name']."'";
  $Val1= "'".$row['Val1']."'";
  $Year= "'".$row['Year']."'";
  $Month="'".$row['Month']."'";

 echo '<button type="button"   onclick="fun('.$Id.','.$Val1.','.$Year.','.$Month.','.$Id.');"  >submit</button>'; 

I've successful installed Google Maps v2 on an emulator using this guide.
You should do the following steps:

• Create a new emulator Nexus S, Android 2.3.3. Don't use Google API.
• Install com.android.vending.apk (Google Play Store, v.3.10.9)
• Install com.google.android.gms.apk (Google Play Service, v.2.0.12)

Just came acreoss this, and since I had the same issue, I'd just post the results I came up with

when parsing, you could update the offset (ie I am parsing a data (1.1.2014) and I only want the date, 1st Jan 2014. On GMT+1 I'd get 31.12.2013. So I offset the value first.

moment(moment.utc('1.1.2014').format());

Well, came in handy for me to support across timezones

IE11 does implement String.prototype.includes so why not using the official Polyfill?

  if (!String.prototype.includes) {
    String.prototype.includes = function(search, start) {
      if (typeof start !== 'number') {
        start = 0;
      }

      if (start + search.length > this.length) {
        return false;
      } else {
        return this.indexOf(search, start) !== -1;
      }
    };
  }

You need to download this from Microsoft: http://www.microsoft.com/en-us/download/details.aspx?id=7435.

The tool is called "Microsoft URL Rewrite Module 2.0 for IIS 7" and is described as follows by Microsoft: "URL Rewrite Module 2.0 provides a rule-based rewriting mechanism for changing requested URL’s before they get processed by web server and for modifying response content before it gets served to HTTP clients"

Adding this to your code android:focusableInTouchMode="true" will make sure that your keypad doesn't appear on startup for your edittext box. You want to add this line to your linear layout that contains the EditTextBox. You should be able to play with this to solve both your problems. I have tested this. Simple solution.

ie: In your app_list_view.xml file

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" 
    android:focusableInTouchMode="true">
    <EditText 
        android:id="@+id/filter_edittext"       
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Search" 
        android:inputType="text" 
        android:maxLines="1"/>
    <ListView 
        android:id="@id/android:list" 
        android:layout_height="fill_parent"
        android:layout_weight="1.0" 
        android:layout_width="fill_parent" 
        android:focusable="true" 
        android:descendantFocusability="beforeDescendants"/>
</LinearLayout> 

------------------ EDIT: To Make keyboard appear on startup -----------------------

This is to make they Keyboard appear on the username edittextbox on startup. All I've done is added an empty Scrollview to the bottom of the .xml file, this puts the first edittext into focus and pops up the keyboard. I admit this is a hack, but I am assuming you just want this to work. I've tested it, and it works fine.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:paddingLeft="20dip"  
    android:paddingRight="20dip">
    <EditText 
        android:id="@+id/userName" 
        android:singleLine="true" 
        android:layout_width="fill_parent"  
        android:layout_height="wrap_content" 
        android:hint="Username"  
        android:imeOptions="actionDone" 
        android:inputType="text"
        android:maxLines="1"
       />
    <EditText 
        android:id="@+id/password" 
        android:password="true" 
        android:singleLine="true"  
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:hint="Password" />
    <ScrollView
        android:id="@+id/ScrollView01"  
        android:layout_height="fill_parent"   
        android:layout_width="fill_parent"> 
    </ScrollView>
</LinearLayout>

If you are looking for a more eloquent solution, I've found this question which might help you out, it is not as simple as the solution above but probably a better solution. I haven't tested it but it apparently works. I think it is similar to the solution you've tried which didn't work for you though.

Hope this is what you are looking for.

Cheers!

Before proceeding:

• Install a proper mergetool. On Linux, I strongly suggest you to use meld:

  sudo apt-get install meld
  

• Configure your mergetool:

  git config --global merge.tool meld
  

Then, iterate in the following way:

git cherry-pick ....
git mergetool
git cherry-pick --continue

var array = new Array(); // or the shortcut: = []
array.push ( {"cool":"34.33","also cool":"45454"} );
array.push (  {"cool":"34.39","also cool":"45459"} );

Your variable is a javascript object {} not an array [].

You could do:

var o = {}; // or the longer form: = new Object()
o.SomeNewProperty = "something";
o["SomeNewProperty"] = "something";

and

var o = { SomeNewProperty: "something" };
var o2 = { "SomeNewProperty": "something" };

Later, you add those objects to your array: array.push (o, o2);

Also JSON is simply a string representation of a javascript object, thus:

var json = '{"cool":"34.33","alsocool":"45454"}'; // is JSON
var o = JSON.parse(json); // is a javascript object
json = JSON.stringify(o); // is JSON again

If you dont want to query for it just create an entity, and then delete it.

Customer customer  = new Customer() {  Id = 1   } ; 
context.AttachTo("Customers", customer);
context.DeleteObject(customer);
context.Savechanges();

Try this:

public class Team
{
    public int TeamId { get; set;} 
    public string Name { get; set; }

    public virtual ICollection<Match> HomeMatches { get; set; }
    public virtual ICollection<Match> AwayMatches { get; set; }
}

public class Match
{
    public int MatchId { get; set; }

    public int HomeTeamId { get; set; }
    public int GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}


public class Context : DbContext
{
    ...

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Match>()
                    .HasRequired(m => m.HomeTeam)
                    .WithMany(t => t.HomeMatches)
                    .HasForeignKey(m => m.HomeTeamId)
                    .WillCascadeOnDelete(false);

        modelBuilder.Entity<Match>()
                    .HasRequired(m => m.GuestTeam)
                    .WithMany(t => t.AwayMatches)
                    .HasForeignKey(m => m.GuestTeamId)
                    .WillCascadeOnDelete(false);
    }
}

Primary keys are mapped by default convention. Team must have two collection of matches. You can't have single collection referenced by two FKs. Match is mapped without cascading delete because it doesn't work in these self referencing many-to-many.

Alternately,

You can use your own Application class and call from wherever you needs (especially non-activities).

public class App extends Application {

    protected static Context context = null;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
    }

    public static Context getContext() {
        return context;
    }

}

And register your Application class :

<application android:name="yourpackage.App" ...

Then call :

App.getContext();

Chrome does not support localhost for CORS requests (a bug opened in 2010, marked WontFix in 2014).

To get around this you can use a domain like lvh.me (which points at 127.0.0.1 just like localhost) or start chrome with the --disable-web-security flag (assuming you're just testing).

OK, so I found the solution here: targetContentOffsetForProposedContentOffset:withScrollingVelocity without subclassing UICollectionViewFlowLayout

I should have searched for targetContentOffsetForProposedContentOffset in the begining.

I posted a CodeProject article that may be what you want.

See: A C# way for indirect width and style formatting.

Basically it is a method, FormatEx, that acts like String.Format, except it allows a centered alignment modifier.

FormatEx("{0,c10}", value);

Means center the value of varArgs[0] in a 10 character wide field, lean right if an extra padding space is required.

FormatEx("{0,c-10}", value);

Means center the value of varArgs[0] in a 10 character wide field, lean left if an extra padding space is required.

Edit: Internally, it is a combination of Joel's PadCenter with some parsing to restructure the format and varArgs for a call to String.Format that does what you want.

min-width and max-width properties do not work the way you expect for table cells. From spec:

In CSS 2.1, the effect of 'min-width' and 'max-width' on tables, inline tables, table cells, table columns, and column groups is undefined.

This hasn't changed in CSS3.

You can use jQuery to achieve this using simple $.get method. .html work like innerHtml and replace the content of your div.

$.get("/YourUrl", {},
      function (returnedHtml) {
      $("#here").html(returnedHtml);
});

And call this using javascript setInterval method.

while facing a very similar issue I watched a function in scope and had the function return the service variable. I have created a js fiddle. you can find the code below.

    var myApp = angular.module("myApp",[]);

myApp.factory("randomService", function($timeout){
    var retValue = {};
    var data = 0;

    retValue.startService = function(){
        updateData();
    }

    retValue.getData = function(){
        return data;
    }

    function updateData(){
        $timeout(function(){
            data = Math.floor(Math.random() * 100);
            updateData()
        }, 500);
    }

    return retValue;
});

myApp.controller("myController", function($scope, randomService){
    $scope.data = 0;
    $scope.dataUpdated = 0;
    $scope.watchCalled = 0;
    randomService.startService();

    $scope.getRandomData = function(){
        return randomService.getData();    
    }

    $scope.$watch("getRandomData()", function(newValue, oldValue){
        if(oldValue != newValue){
            $scope.data = newValue;
            $scope.dataUpdated++;
        }
            $scope.watchCalled++;
    });
});

On SQL Server 2008+ it is possible to use Table Valued Parameters to pass in a table variable to a dynamic SQL statement as long as you don't need to update the values in the table itself.

So from the code you posted you could use this approach for @TSku but not for @RelPro

Example syntax below.

CREATE TYPE MyTable AS TABLE 
( 
Foo int,
Bar int
);
GO


DECLARE @T AS MyTable;

INSERT INTO @T VALUES (1,2), (2,3)

SELECT *,
        sys.fn_PhysLocFormatter(%%physloc%%) AS [physloc]
FROM @T

EXEC sp_executesql
  N'SELECT *,
        sys.fn_PhysLocFormatter(%%physloc%%) AS [physloc]
    FROM @T',
  N'@T MyTable READONLY',
  @T=@T 

The physloc column is included just to demonstrate that the table variable referenced in the child scope is definitely the same one as the outer scope rather than a copy.

The only solution that fully works for me is a combination of Alex Volovoy's code with application restart mechanism:

void restartApplication() {
    Intent i = new Intent(MainTabActivity.context, MagicAppRestart.class);
    i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    MainTabActivity.context.startActivity(i);
}


/** This activity shows nothing; instead, it restarts the android process */
public class MagicAppRestart extends Activity {
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        finish();
    }

    protected void onResume() {
        super.onResume();
        startActivityForResult(new Intent(this, MainTabActivity.class), 0);         
    }
}

As seen on this example from Twitter, add this before the line that includes the responsive styles declarations:

<style> 
    body {
        padding-top: 60px;
    }
</style>

Like so:

<link href="Z/bootstrap/css/bootstrap.min.css" rel="stylesheet" />
<style type="text/css">
    body {
        padding-top: 60px;
    }
</style>
<link href="Z/bootstrap/css/bootstrap-responsive.min.css" rel="stylesheet" />

A simple way to protect a file with no requirement for a separate login page - just add this to the top of the page:

Change secretuser and secretpassword to your user/password.

$user = $_POST['user'];
$pass = $_POST['pass'];

if(!($user == "secretuser" && $pass == "secretpassword"))
{
    echo '<html><body><form method="POST" action="'.$_SERVER['REQUEST_URI'].'">
            Username: <input type="text" name="user"></input><br/>
            Password: <input type="password" name="pass"></input><br/>
            <input type="submit" name="submit" value="Login"></input>
            </form></body></html>';
    exit();
}

Instead of step="any", which allows for any number of decimal places, use step=".01", which allows up to two decimal places.

More details in the spec: https://www.w3.org/TR/html/sec-forms.html#the-step-attribute

You can use this function to get resource ID.

public static int getResourceId(String pVariableName, String pResourcename, String pPackageName) 
{
    try {
        return getResources().getIdentifier(pVariableName, pResourcename, pPackageName);
    } catch (Exception e) {
        e.printStackTrace();
        return -1;
    } 
}

So if you want to get for drawable call function like this

getResourceId("myIcon", "drawable", getPackageName());

and for string you can call it like this

getResourceId("myAppName", "string", getPackageName());

Yes, just create a directory in your solution like lib/, and then add your dll to that directory in the filesystem and add it in the project (Add->Existing Item->etc). Then add the reference based on your project.

I have done this several times under svn and under cvs.

There isn't one built in, but it's simple to roll your own, as demonstrated here:

import operator
def prod(factors):
    return reduce(operator.mul, factors, 1)

See answers to this question:

Which Python module is suitable for data manipulation in a list?

I know the topic is old, but I just fell on it after a google search so... here is another solution:

$array_merged = array_merge($array_going_first, $array_going_second);

This one seems pretty clean to me, it works just fine!

Same solution worked as suggested by hpereira The issue was due to JRE version was 32 bit and not 64 Bit Check with java -version to see if your Java is 64 bit

C:\>java -version
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) **64-Bit Server** VM (build 25.192-b12, mixed mode)

I tried "ManiIOT"'s solution and it worked surprisingly. I've added another role (Compute Admin Role) for my google user account from IAM admin. Then stopped and restarted the VM. Afterwards 'sudo passwd' let me to generate a new password for the user.

So here are steps.

1. Go to IAM & Admin
2. Select IAM
3. Find your user name service account (basically your google account) and click Edit-member
4. Add another role --> select 'Compute Engine' - 'Compute Admin'
5. Restart your Compute VM
6. open SSH shell and run the command 'sudo passwd'
7. enter a brand new password. Voilà!

You can actually use C# generics for this to make it real easy:

        var file = new List<string>(System.IO.File.ReadAllLines("C:\\path"));
        file.RemoveAt(12);
        File.WriteAllLines("C:\\path", file.ToArray());

If there are multiple commits, you can use git rebase -i to squash two commits into one.

If there are only two commits you want to merge, and they are the "most recent two", the following commands can be used to combine the two commits into one:

git reset --soft "HEAD^"
git commit --amend

Missing config header

Just add [mysqld] as first line in the /etc/mysql/my.cnf file.

Example

[mysqld]
default-time-zone = "+08:00"

Afterwards, remember to restart your MySQL Service.

sudo mysqld stop
sudo mysqld start

You have to figure out if the string is ascii encoded or encoded with a multi-byte format.

In the former case, you can just use strlen.

In the latter case you need to find the number of bytes per character.

the strlen documentation gives an example of how to do it : http://www.php.net/manual/en/function.strlen.php#72274

array_search('20120504', array_keys($your_array));

Double-check that you haven't enabled backface-visibility on any of the containing elements, as that will wreck position: fixed. For me, I was using a CSS3 animation library...

The issue you're having is with the type of quantifier. You're using a greedy quantifier in your first group (index 1 - index 0 represents the whole Pattern), which means it'll match as much as it can (and since it's any character, it'll match as many characters as there are in order to fulfill the condition for the next groups).

In short, your 1st group .* matches anything as long as the next group \\d+ can match something (in this case, the last digit).

As per the 3rd group, it will match anything after the last digit.

If you change it to a reluctant quantifier in your 1st group, you'll get the result I suppose you are expecting, that is, the 3000 part.

Note the question mark in the 1st group.

String line = "This order was placed for QT3000! OK?";
Pattern pattern = Pattern.compile("(.*?)(\\d+)(.*)");
Matcher matcher = pattern.matcher(line);
while (matcher.find()) {
    System.out.println("group 1: " + matcher.group(1));
    System.out.println("group 2: " + matcher.group(2));
    System.out.println("group 3: " + matcher.group(3));
}

Output:

group 1: This order was placed for QT
group 2: 3000
group 3: ! OK?

More info on Java Pattern here.

Finally, the capturing groups are delimited by round brackets, and provide a very useful way to use back-references (amongst other things), once your Pattern is matched to the input.

In Java 6 groups can only be referenced by their order (beware of nested groups and the subtlety of ordering).

In Java 7 it's much easier, as you can use named groups.

Another, perhaps inefficient, solution would be to include the image under an img element set to visibility: hidden;. Then make the background-image of the surrounding div the same as the image.

This will set the surrounding div to the size of the image in the img element but display it as a background.

<div style="background-image: url(http://your-image.jpg);">
 <img src="http://your-image.jpg" style="visibility: hidden;" />
</div>

You do this in 3 different ways:

1. Before you do an INSERT, always issue a BEGIN; statement. This will turn off autocommits. You will need to do a COMMIT; once you want your data to be persisted in the database.

2. Use autocommit=0; every time you instantiate a database connection.

3. For a global setting, add a autocommit=0 variable in your my.cnf configuration file in MySQL.

You can be selective of what div or part of your page can have checkboxes checked and which don't. I came across the scenario where I have two forms in my page and one have prefilled values(for update) and other need to be filled fresh.

$('#newFormId input[type=checkbox]').attr('checked',false);

this will make only checkboxes in form with id newFormId as unchecked.

If you made a merge on Github and are seeing the error below. You need to pull (fetch and commit) the changes from the remote server before it will recognize the merge on your local. After doing this, Git will allow you to delete the branch without giving you the error.

error: The branch 'x' is not fully merged. If you are sure you want to delete it, run 'git branch -D 'x'.

since function is first-class citizen, you can write small wrapper (from Alex answers)

def repeat(f, N):
    for _ in itertools.repeat(None, N): f()

then you can pass function as argument.

I would do something like this

DEMO in JsBin: http://jsbin.com/ofiqur/1/

  <a href="#" id="showmenu">Click Here</a>
  <div class="menu">
    <ul>
      <li><a href="#">Button 1</a></li>
      <li><a href="#">Button 2</a></li>
      <li><a href="#">Button 3</a></li>
    </ul>
  </div>

and in jQuery as simple as

var min = "-100px", // remember to set in css the same value
    max = "0px";

The standard method to generate a number (without a utility method) in a range is to just use the double with the range:

long range = 1234567L;
Random r = new Random()
long number = (long)(r.nextDouble()*range);

will give you a long between 0 (inclusive) and range (exclusive). Similarly if you want a number between x and y:

long x = 1234567L;
long y = 23456789L;
Random r = new Random()
long number = x+((long)(r.nextDouble()*(y-x)));

will give you a long from 1234567 (inclusive) through 123456789 (exclusive)

Note: check parentheses, because casting to long has higher priority than multiplication.

I was also searching same answer, because at some point of time I needed total_count with distinct values along with limit/offset.

Because it's little tricky to do- To get total count with distinct values along with limit/offset. Usually it's hard to get total count with limit/offset. Finally I got the way to do -

SELECT DISTINCT COUNT(*) OVER() as total_count, * FROM table_name limit 2 offset 0;

Query performance is also high.

Syntax refers to the structure of a language, tracing its etymology to how things are put together.
For example you might require the code to be put together by declaring a type then a name and then a semicolon, to be syntactically correct.

Type token;

On the other hand, the semantics is about meaning. A compiler or interpreter could complain about syntax errors. Your co-workers will complain about semantics.

What version of Excel?

In general, you cannot change the column letters. They are part of the Excel system.

You can use a row in the sheet to enter headers for a table that you are using. The table headers can be descriptive column names.

In Excel 2007 and later, you can convert a range of data into an Excel Table (Insert Ribbon > Table). An Excel Table can use structured table references instead of cell addresses, so the labels in the first row of the table now serve as a name reference for the data in the column.

If you have an Excel Table in your sheet (Excel 2007 and later) and scroll down, the column letters will be replaced with the column headers for the table column.

If this does not answer your question, please consider editing your question to include the detail you want to learn about.

You can't resize an image without losing some quality, simply because you are reducing the number of pixels.

Don't reduce the size client side, because browsers don't do a good job of resizing images.

What you can do is programatically change the size before you render it, or as a user uploads it.

Here is an article that explains one way to do this in c#: http://www.codeproject.com/KB/GDI-plus/imageresize.aspx

You can use

<div class="col-sm-12" *ngIf="event.attendees?.length">

Without event.attendees?.length > 0 or even event.attendees?length != 0

Because ?.length already return boolean value.

If in array will be something it will display it else not.

Below are scripts for emptying and deleting a Kafka topic assuming localhost as the zookeeper server and Kafka_Home is set to the install directory:

The script below will empty a topic by setting its retention time to 1 second and then removing the configuration:

#!/bin/bash
echo "Enter name of topic to empty:"
read topicName
/$Kafka_Home/bin/kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name $topicName --add-config retention.ms=1000
sleep 5
/$Kafka_Home/bin/kafka-configs --zookeeper localhost:2181 --alter --entity-type topics --entity-name $topicName --delete-config retention.ms

To fully delete topics you must stop any applicable kafka broker(s) and remove it's directory(s) from the kafka log dir (default: /tmp/kafka-logs) and then run this script to remove the topic from zookeeper. To verify it's been deleted from zookeeper the output of ls /brokers/topics should no longer include the topic:

#!/bin/bash
echo "Enter name of topic to delete from zookeeper:"
read topicName
/$Kafka_Home/bin/zookeeper-shell localhost:2181 <<EOF
rmr /brokers/topics/$topicName
ls /brokers/topics
quit
EOF

sending tag <img src="c:\images\mypic.jpg"> would cause user browser to access image from his filesystem. if you have to store images in folder located in c:\images i would suggest to create an servlet like images.jsp, that as a parameter takes name of a file, then sets servlet response content to an image/jpg and then loads bytes of image from server location and put it to a response.

But what you use to create your application? is it pure servlet? Spring? JSF?

Here you can find some info about, how to do it.

There are three parts:

1. Add a 'shebang' at the top of your script which tells how to execute your script
2. Give the script 'run' permissions.
3. Make the script in your PATH so you can run it from anywhere.

Adding a shebang

You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:

#!path/to/interpretter

To find the path to your python interpretter on your machine you can run the command:

which python

This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:

#!/usr/bin/python

Run Permissions

You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:

chmod +x myscript.py

Add the script to your path

The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:

echo $PATH

This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:

which <commandname>

Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:

export PATH=/my/directory/with/pythonscript:$PATH

Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile

Use this example :

<button name="nameButton" id="idButton" title="your title" class="btn btn-secondary" onclick="location.href='@Url.Action( "Index","Controller" new {  id = Item.id })';return false;">valueButton</button>

The problem is that codeAddress() doesn't have enough scope to be callable from the button. You must declare it outside the callback to ready():

function codeAddress() {
    var address = document.getElementById("formatedAddress").value;
    geocoder.geocode( { 'address': address}, function(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
        }
    });
}


$(document).ready(function(){
    // Do stuff here, including _calling_ codeAddress(), but not _defining_ it!
});

Try GetElementsByTagName method of XMLDocument class to read specific data or LoadXml method to read all data to xml document.

I also got the same issue, but I fix it by changing my key file permission to 600.

sudo chmod 600 /path/to/my/key.pem

Here are simple regex to understand (verified, and no preceding 0)

Between 0 to 100 (Try it here):

^(0|[1-9][0-9]?|100)$

Between 1 to 100 (Try it here):

^([1-9][0-9]?|100)$

For all who came to this post and tried all may probably using nodemon or forever to do this. For example if you run PORT=6060 Nodemon You might get the same error that port 6060 is already in use.

If this is the case just run your project without nodemon if you really need to define port during run. Alternatively you can define port in your file itself if you wanna stick to nodemon.

For me I do this now PORT=6060 node app.js

Another (maybe faster for large directories) approach:

$ find dir1 | sed 's,^[^/]*/,,' | sort > dir1.txt && find dir2 | sed 's,^[^/]*/,,' | sort > dir2.txt
$ diff dir1.txt dir2.txt

The sed command removes the first directory component thanks to Erik`s post)

You can use range quantifier {min,max} to specify minimum of 1 digit and maximum of 6 digits as:

^[0-9]{1,6}$

Explanation:

^     : Start anchor
[0-9] : Character class to match one of the 10 digits
{1,6} : Range quantifier. Minimum 1 repetition and maximum 6.
$     : End anchor

Why did your regex not work ?

You were almost close on the regex:

^[0-9][0-9]\?[0-9]\?[0-9]\?[0-9]\?[0-9]\?$

Since you had escaped the ? by preceding it with the \, the ? was no more acting as a regex meta-character ( for 0 or 1 repetitions) but was being treated literally.

To fix it just remove the \ and you are there.

See it on rubular.

The quantifier based regex is shorter, more readable and can easily be extended to any number of digits.

Your second regex:

^[0-999999]$

is equivalent to:

^[0-9]$

which matches strings with exactly one digit. They are equivalent because a character class [aaaab] is same as [ab].

Easier and more succinct with || ...:

$(document).ready(function(){


  var str = ((document.getElementById("cal_preview")||{}).value)||"";
  var str1 = ((document.getElementById("year")||{}).value)||"";
  var str2 = ((document.getElementById("holiday")||{}).value)||"";
  var str3 = ((document.getElementById("cal_option")||{}).value)||"";


    if (str=="" && str1=="" && str2=="" && str3=="" )
      {
        document.getElementById("calendar_preview").innerHTML="";
          return;
        } 
      if (window.XMLHttpRequest)
      {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
      }
      else
      {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
      }

      xmlhttp.onreadystatechange=function()
      {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
          {
            document.getElementById("calendar_preview").innerHTML=xmlhttp.responseText;
          }
      }

    var url = calendar_preview_vars.plugin_url + "?id=" + str +"&"+"y="+str1+"&"+"h="+str2+"&"+"opt="+str3;
    xmlhttp.open("GET",url,true);
    xmlhttp.send(); 


});

Use any of the following:

String str = String.valueOf('c');
String str = Character.toString('c');
String str = 'c' + "";

If the 2nd company is happy for you to access their content in an IFrame then they need to take the restriction off - they can do this fairly easily in the IIS config.

There's nothing you can do to circumvent it and anything that does work should get patched quickly in a security hotfix. You can't tell the browser to just render the frame if the source content header says not allowed in frames. That would make it easier for session hijacking.

If the content is GET only you don't post data back then you could get the page server side and proxy the content without the header, but then any post back should get invalidated.

By default, no you can't know if a variable (or pointer) has or hasn't been initialized. However, since everyone else is telling you the "easy" or "normal" approach, I'll give you something else to think about. Here's how you could keep track of something like that (no, I personally would never do this, but perhaps you have different needs than me).

class MyVeryCoolInteger
{
public:
    MyVeryCoolInteger() : m_initialized(false) {}

    MyVeryCoolInteger& operator=(const int integer)
    {
        m_initialized = true;
        m_int = integer;
        return *this;
    }

    int value()
    {
        return m_int;
    }

    bool isInitialized()
    {
        return m_initialized;
    }

private:
    int m_int;
    bool m_initialized;
};

If you're using a graphical tool. It shows you the schema right next to the table name. In case of DB Browser For Sqlite, click to open the database(top right corner), navigate and open your database, you'll see the information populated in the table as below.

right click on the record/table_name, click on copy create statement and there you have it.

Hope it helped some beginner who failed to work with the commandline.

If you have a large number of sequentially named data frames you can create a list of the desired subset of data frames like this:

d1 <- data.frame(y1=c(1,2,3), y2=c(4,5,6))
d2 <- data.frame(y1=c(3,2,1), y2=c(6,5,4))
d3 <- data.frame(y1=c(6,5,4), y2=c(3,2,1))
d4 <- data.frame(y1=c(9,9,9), y2=c(8,8,8))

my.list <- list(d1, d2, d3, d4)
my.list

my.list2 <- lapply(paste('d', seq(2,4,1), sep=''), get)
my.list2

where my.list2 returns a list containing the 2nd, 3rd and 4th data frames.

[[1]]
  y1 y2
1  3  6
2  2  5
3  1  4

[[2]]
  y1 y2
1  6  3
2  5  2
3  4  1

[[3]]
  y1 y2
1  9  8
2  9  8
3  9  8

Note, however, that the data frames in the above list are no longer named. If you want to create a list containing a subset of data frames and want to preserve their names you can try this:

list.function <-  function() { 

     d1 <- data.frame(y1=c(1,2,3), y2=c(4,5,6))
     d2 <- data.frame(y1=c(3,2,1), y2=c(6,5,4))
     d3 <- data.frame(y1=c(6,5,4), y2=c(3,2,1))
     d4 <- data.frame(y1=c(9,9,9), y2=c(8,8,8))

     sapply(paste('d', seq(2,4,1), sep=''), get, environment(), simplify = FALSE) 
} 

my.list3 <- list.function()
my.list3

which returns:

> my.list3
$d2
  y1 y2
1  3  6
2  2  5
3  1  4

$d3
  y1 y2
1  6  3
2  5  2
3  4  1

$d4
  y1 y2
1  9  8
2  9  8
3  9  8

> str(my.list3)
List of 3
 $ d2:'data.frame':     3 obs. of  2 variables:
  ..$ y1: num [1:3] 3 2 1
  ..$ y2: num [1:3] 6 5 4
 $ d3:'data.frame':     3 obs. of  2 variables:
  ..$ y1: num [1:3] 6 5 4
  ..$ y2: num [1:3] 3 2 1
 $ d4:'data.frame':     3 obs. of  2 variables:
  ..$ y1: num [1:3] 9 9 9
  ..$ y2: num [1:3] 8 8 8

> my.list3[[1]]
  y1 y2
1  3  6
2  2  5
3  1  4

> my.list3$d4
  y1 y2
1  9  8
2  9  8

adding to scotty's answer:

Option 1: Either include this in your JS file:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.0rc1/angular-route.min.js"></script>

Option 2: or just use the URL to download 'angular-route.min.js' to your local.

and then (whatever option you choose) add this 'ngRoute' as dependency.

explained: var app = angular.module('myapp', ['ngRoute']);

Cheers!!!

Yes you can start with the Wikipedia article explaining the Big O notation, which in a nutshell is a way of describing the "efficiency" (upper bound of complexity) of different type of algorithms. Or you can look at an earlier answer where this is explained in simple english

Linux's memory management philosophy is "Free memory is wasted memory".

I assume that the next two lines will show how much memory is in "Buffers" and how much is "Cached". While there is a difference between the two (please don't ask what that difference is :) they both roughly add up to the amount of memory used to cache file data and metadata.

A far more useful guide to free memory on a Linux system is the free(1) command; on my desktop, it reports information like this:

$ free -m
             total       used       free     shared    buffers     cached
Mem:          5980       1055       4924          0         91        374
-/+ buffers/cache:        589       5391
Swap:         6347          0       6347

The +/- buffers/cache: line is the magic line, it reports that I've really got around 589 megs of actively required process memory, and around 5391 megs of 'free' memory, in the sense that the 91+374 megabytes of buffers/cached memory can be thrown away if the memory could be more profitably used elsewhere.

(My machine has been up for about three hours, doing nearly nothing but stackoverflow, which is why I have so much free memory.)

If Android doesn't ship with free(1), you can do the math yourself with the /proc/meminfo file; I just like the free(1) output format. :)

It might be easiest to try the RCurl package. Install the package and try the following:

# install.packages("RCurl")
library(RCurl)

x <- getURL(URL)
## Or 
## x <- getURL(URL, ssl.verifypeer = FALSE)
out <- read.csv(textConnection(x))
head(out[1:6])

There are 3 possible ways:

1) WidgetsBinding.instance.addPostFrameCallback((_) => yourFunc(context));

2) Future.delayed(Duration.zero, () => yourFunc(context));

3) Timer.run(() => yourFunc(context));

As for context, I needed it for use in Scaffold.of(context) after all my widgets were rendered.

But in my humble opinion, the best way to do it is this:

void main() async {
  WidgetsFlutterBinding.ensureInitialized(); //all widgets are rendered here
  await yourFunc();
  runApp( MyApp() );
}

Text boxes in worksheets are sometimes not updated when their text or formatting is changed, and even the DoEvent command does not help.

As there is no command in Excel to refresh a worksheet in the way a user form can be refreshed, it is necessary to use a trick to force Excel to update the screen.

The following commands seem to do the trick:

- ActiveSheet.Calculate    
- ActiveWindow.SmallScroll    
- Application.WindowState = Application.WindowState

I hope you will find this useful.

$query1="SELECT TIMESTAMPDIFF (YEAR, YOUR_DOB_COLUMN, CURDATE()) AS age FROM your_table WHERE id='$user_id'";
$res1=mysql_query($query1);
$row=mysql_fetch_array($res1);
echo $row['age'];

public static boolean isIpv4(String ipAddress) {
    if (ipAddress == null) {
        return false;
    }
    String ip = "^(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|[1-9])\\."
            + "(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)\\."
            + "(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)\\."
            + "(1\\d{2}|2[0-4]\\d|25[0-5]|[1-9]\\d|\\d)$";
    Pattern pattern = Pattern.compile(ip);
    Matcher matcher = pattern.matcher(ipAddress);
    return matcher.matches();
}

You could try to use ng-class.
Here is my simple example:
http://plnkr.co/edit/wS3QkQ5dvHNdc6Lb8ZSF?p=preview

<div ng-repeat="object in objects">
  <span ng-class="{'disabled': object.status}" ng-click="disableIt(object)">
    {{object.value}}
  </span>
</div>

The status is a custom attribute of object, you could name it whatever you want.
The disabled in ng-class is a CSS class name, the object.status should be true or false

You could change every object's status in function disableIt.
In your Controller, you could do this:

$scope.disableIt = function(obj) {
  obj.status = !obj.status
}

I stole this convienent class from somewhere here at StackOverflow to convert anything streamable to a string:

// make_string
class make_string {
public:
  template <typename T>
  make_string& operator<<( T const & val ) {
    buffer_ << val;
    return *this;
  }
  operator std::string() const {
    return buffer_.str();
  }
private:
  std::ostringstream buffer_;
};

And then you use it as;

string str = make_string() << 6 << 8 << "hello";

Quite nifty!

Also I use this function to convert strings to anything streamable, althrough its not very safe if you try to parse a string not containing a number; (and its not as clever as the last one either)

// parse_string
template <typename RETURN_TYPE, typename STRING_TYPE>
RETURN_TYPE parse_string(const STRING_TYPE& str) {
  std::stringstream buf;
  buf << str;
  RETURN_TYPE val;
  buf >> val;
  return val;
}

Use as:

int x = parse_string<int>("78");

You might also want versions for wstrings.

All answers contain part of the answer. Let me try to combine all in one.

Quick setup "file browser" mode on freshly installed nginx server:

1. Edit default config for nginx:

   sudo vim /etc/nginx/sites-available/default
   

2. Add following to config section:

   location /myfolder {  # new url path
      alias /home/username/myfolder/; # directory to list
      autoindex on;
   }
   

3. Create folder and sample file there:

   mkdir -p /home/username/myfolder/
   ls -la >/home/username/myfolder/mytestfile.txt
   

4. Restart nginx

   sudo systemctl restart nginx
   

5. Check result: http://<your-server-ip>/myfolder for example http://192.168.0.10/myfolder/

For Visual Basic:

[Enum].GetNames(typeof(MyEnum)).Length did not work with me, but [Enum].GetNames(GetType(Animal_Type)).length did.

Unfortunately, AFAIK you cannot run multiple SQL statements under one named query in Access in the traditional sense.

You can make several queries, then string them together with VBA (DoCmd.OpenQuery if memory serves).

You can also string a bunch of things together with UNION if you wish.

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

I've grabbed the entries() method of formData from @moison answer and from MDN it's said that :

The FormData.entries() method returns an iterator allowing to go through all key/value pairs contained in this object. The key of each pair is a USVString object; the value either a USVString, or a Blob.

but the only issue is that mobile browser (android and safari are not supported ) and IE and Safari desktop too

but basically here is my approach :

let theForm =  document.getElementById("contact"); 

theForm.onsubmit = function(event) {
    event.preventDefault();

    let rawData = new FormData(theForm);
    let data = {};

   for(let pair of rawData.entries()) {
     data[pair[0]] = pair[1]; 
    }
    let contactData = JSON.stringify(data);
    console.warn(contactData);
    //here you can send a post request with content-type :'application.json'

};

the code can be found here

This is an old question but there is some newer guidance in PEP 565 that to turn off all warnings if you're writing a python application you should use:

import sys
import warnings

if not sys.warnoptions:
    warnings.simplefilter("ignore")

The reason this is recommended is that it turns off all warnings by default but crucially allows them to be switched back on via python -W on the command line or PYTHONWARNINGS.

Here's the complete wget command that worked for me to download files from a server's directory (ignoring robots.txt):

wget -e robots=off --cut-dirs=3 --user-agent=Mozilla/5.0 --reject="index.html*" --no-parent --recursive --relative --level=1 --no-directories http://www.example.com/archive/example/5.3.0/

Here are three ways you can check if dict is empty. I prefer using the first way only though. The other two ways are way too wordy.

test_dict = {}

if not test_dict:
    print "Dict is Empty"


if not bool(test_dict):
    print "Dict is Empty"


if len(test_dict) == 0:
    print "Dict is Empty"

if you have

on your js do :

var imgData = 'data:image/jpeg;base64,/veryLongBase64Encode....'
var doc = new jsPDF()

doc.setFontSize(40)
doc.addImage(imgData, 'JPEG', 15, 40, 180, 160)

Can see example here

Good question! You can try the following code for this. =)

This code uses ast.literal_eval() to find the data type of the input (age). Then it follows the following algorithm:

1. Ask user to input her/his age.

   1.1. If age is float or int data type:

   • Check if age>=18. If age>=18, print appropriate output and exit.

   • Check if 0<age<18. If 0<age<18, print appropriate output and exit.

   • If age<=0, ask the user to input a valid number for age again, (i.e. go back to step 1.)

   1.2. If age is not float or int data type, then ask user to input her/his age again (i.e. go back to step 1.)

Here is the code.

from ast import literal_eval

''' This function is used to identify the data type of input data.'''
def input_type(input_data):
    try:
        return type(literal_eval(input_data))
    except (ValueError, SyntaxError):
        return str

flag = True

while(flag):
    age = raw_input("Please enter your age: ")

    if input_type(age)==float or input_type(age)==int:
        if eval(age)>=18: 
            print("You are able to vote in the United States!") 
            flag = False 
        elif eval(age)>0 and eval(age)<18: 
            print("You are not able to vote in the United States.") 
            flag = False
        else: print("Please enter a valid number as your age.")

    else: print("Sorry, I didn't understand that.") 

Try the below code to unprotect the workbook. It works for me just fine in excel 2010 but I am not sure if it will work in 2013.

I would suggest to refer the page. Official suggestion

https://docs.angularjs.org/guide/$location

I'd like to give more codes to make it clear.

struct A
{
    operator bool() const { return true; }
};

struct B
{
    explicit operator bool() const { return true; }
};

int main()
{
    A a1;
    if (a1) cout << "true" << endl; // OK: A::operator bool()
    bool na1 = a1; // OK: copy-initialization selects A::operator bool()
    bool na2 = static_cast<bool>(a1); // OK: static_cast performs direct-initialization

    B b1;     
    if (b1) cout << "true" << endl; // OK: B::operator bool()
    // bool nb1 = b1; // error: copy-initialization does not consider B::operator bool()
    bool nb2 = static_cast<bool>(b1); // OK: static_cast performs direct-initialization
}

This is simple solution for this warning:

You can change the eclipse tomcat server configuration. Open the server view, double click on you server to open server configuration. There is a server Option Tab. inside that tab click check Box to activate "Publish module contents to separate XML files".

Finally, restart your server, the message must disappear.

Data transfer between two platform requires a common data format. JSON is a common global format to send cross platform data.

drawChart(600/50, JSON.parse('<?php echo json_encode($day); ?>'), JSON.parse('<?php echo json_encode($week); ?>'), JSON.parse('<?php echo json_encode($month); ?>'), JSON.parse('<?php echo json_encode(createDatesArray(cal_days_in_month(CAL_GREGORIAN, date('m',strtotime('-1 day')), date('Y',strtotime('-1 day'))))); ?>'))

This is the answer to your question. The answer may look very complex. You can see a simple example describing the communication between server side and client side here

$employee = array(
 "employee_id" => 10011,
   "Name" => "Nathan",
   "Skills" =>
    array(
           "analyzing",
           "documentation" =>
            array(
              "desktop",
                "mobile"
             )
        )
);

Conversion to JSON format is required to send the data back to client application ie, JavaScript. PHP has a built in function json_encode(), which can convert any data to JSON format. The output of the json_encode function will be a string like this.

{
    "employee_id": 10011,
    "Name": "Nathan",
    "Skills": {
        "0": "analyzing",
        "documentation": [
            "desktop",
            "mobile"
        ]
    }
}

On the client side, success function will get the JSON string. Javascript also have JSON parsing function JSON.parse() which can convert the string back to JSON object.

$.ajax({
        type: 'POST',
        headers: {
            "cache-control": "no-cache"
        },
        url: "employee.php",
        async: false,
        cache: false,
        data: {
            employee_id: 10011
        },
        success: function (jsonString) {
            var employeeData = JSON.parse(jsonString); // employeeData variable contains employee array.
    });

If you want to do it right, you need something like this:

use autodie qw(open sysseek sysread truncate);

my $file = shift;
open my $fh, '+>>', $file;
my $pos = tell $fh;
sysseek $fh, $pos - 1, 0;
sysread $fh, my $buf, 1 or die 'No data to read?';

if($buf eq "\n"){
    truncate $fh, $pos - 1;
}

We open the file for reading and appending; opening for appending means that we are already seeked to the end of the file. We then get the numerical position of the end of the file with tell. We use that number to seek back one character, and then we read that one character. If it's a newline, we truncate the file to the character before that newline, otherwise, we do nothing.

This runs in constant time and constant space for any input, and doesn't require any more disk space, either.

The same thing was when I've created a new Configuration and Build Scheme.

So the solution for me was to run

pod install

for this newly created Configuration.

use the attribute data-rel="back" on the anchor tag instead of the hash navigation, this will take you to the previous page

Look at back linking: Here

You probably have some other "Date" class imported somewhere (or you have a Date class in you package, which does not need to be imported). With "import java.util.*" you are using the "other" Date. In this case it's best to explicitly specify java.util.Date in the code.

Or better, try to avoid naming your classes "Date".

Watching this course https://app.pluralsight.com/library/courses/angular-2-getting-started-update/discussion

The author explains that new version of JavaScript has for of and for in, the for of is to enumerate objects and the for in is to enumerate the index of the array.

Liviu's answer was extremely helpful for me. Hope this is not bad form but i made a fiddle that may help someone else out in the future.

Two important pieces that are needed are:

    $scope.entities = [{
    "title": "foo",
    "id": 1
}, {
    "title": "bar",
    "id": 2
}, {
    "title": "baz",
    "id": 3
}];
$scope.selected = [];

Because the purpose of an interface is to allow polymorphism, being able to pass an instance of any number of defined classes that have all been defined to implement the defined interface... guaranteeing that within your polymorphic call, the code will be able to find the method you are calling. it makes no sense to allow a static method to implement the interface,

How would you call it??

public interface MyInterface { void MyMethod(); }
public class MyClass: MyInterface
{
    public static void MyMethod() { //Do Something; }
}

 // inside of some other class ...  
 // How would you call the method on the interface ???
    MyClass.MyMethod();  // this calls the method normally 
                         // not through the interface...

    // This next fails you can't cast a classname to a different type... 
    // Only instances can be Cast to a different type...
    MyInterface myItf = MyClass as MyInterface;  

Okey, here I am going to share what I have done to install SciPy on my Windows PC without the command line.

My PC configuration is Windows 7 64-bit and Python 2.7

• First I download the required packages form http://www.lfd.uci.edu/~gohlke/pythonlibs/ (which version match your configuration EX: cp27==>python2.7 & cp35==>3.5)
• Second I extract the file using 7-Zip (also can be used any zipper like WinRAR)
• Third I copy the scipy folder which I extracted and paste it into C:\Python27\Lib\site-packages (or put it where the exact location is in your PC like ..\..\Lib\site-packages)

NOTE: You have to install NumPy first before installing SciPy in this same way.

try

<div class="container">
    <div class="row">
        <div class="col-md-12">header section</div>

    </div>
     <div class="row fill">
        <div class="col-md-4">Navigation</div>
        <div class="col-md-8">Content</div>

    </div>
</div>

css for .fill class is below

 .fill{
    width:100%;
    height:100%;
    min-height:100%;
    padding:10px;
    color:#efefef;
    background: blue;
}
.col-md-12
{
    background: red;

}

.col-md-4
{
    background: yellow;
    height:100%;
    min-height:100%;

}
.col-md-8
{
    background: green;
    height:100%;
    min-height:100%;

}

For your reference just look into the fiddle.

CREATE PROCEDURE SP_Reporting(IN tablename VARCHAR(20))
proc_label:BEGIN
     IF tablename IS NULL THEN
          LEAVE proc_label;
     END IF;

     #proceed the code
END;

Here is example with only CSS for that. In example I'm using SASS and SLIM.

https://codepen.io/Darex1991/pen/zBxPxe

Slim:

a.btn.btn--joined-state
  span joined
  span leave

SASS:

=animate($property...)
  @each $vendor in ('-webkit-', '')
    #{$vendor}transition-property: $property
    #{$vendor}transition-duration: .3s
    #{$vendor}transition-timing-function: ease-in

=visible
  +animate(opacity, max-height, visibility)
  max-height: 150px
  opacity: 1
  visibility: visible

=invisible
  +animate(opacity, max-height, visibility)
  max-height: 0
  opacity: 0
  visibility: hidden

=transform($var)
  @each $vendor in ('-webkit-', '-ms-', '')
    #{$vendor}transform: $var

.btn
  border: 1px solid blue

  &--joined-state
    position: relative
    span
      +animate(opacity)

    span:last-of-type
      +invisible
      +transform(translateX(-50%))
      position: absolute
      left: 50%

    &:hover
      span:first-of-type
        +invisible
      span:last-of-type
        +visible
        border-color: blue

What about :

Map<String, String> s = Collections.emptyMap();

I believe this is a perfect use-case for Eloquent events (http://laravel.com/docs/eloquent#model-events). You can use the "deleting" event to do the cleanup:

class User extends Eloquent
{
    public function photos()
    {
        return $this->has_many('Photo');
    }

    // this is a recommended way to declare event handlers
    public static function boot() {
        parent::boot();

        static::deleting(function($user) { // before delete() method call this
             $user->photos()->delete();
             // do the rest of the cleanup...
        });
    }
}

You should probably also put the whole thing inside a transaction, to ensure the referential integrity..

1. Open Google Chrome.
2. Click Menu on the upper right side. Beside the STAR symbol (Bookmark).
3. Click Show Advanced Settings.
4. Scroll down and find Network.
5. Click Change proxy settings.
6. On the Connections tab, click LAN settings.
7. Uncheck "Use a proxy server for your LAN."
8. Then click OK.

Hope it helps .

write direct password into config>database.php

Change to

I am use to read full data:

// inputStream is one instance InputStream
byte[] data = new byte[inputStream.available()];
inputStream.read(data);
String dataString = new String(data);

var input = {"document":
  {"people":[
    {"name":["Harry Potter"],"age":["18"],"gender":["Male"]},
    {"name":["hermione granger"],"age":["18"],"gender":["Female"]},
  ]}
}

var keys = [];
for(var i = 0;i<input.document.people.length;i++)
{
    Object.keys(input.document.people[i]).forEach(function(key){
        if(keys.indexOf(key) == -1)
        {
            keys.push(key);
        }
    });
}
console.log(keys);

my quick answer with basic java arithmetic calculation is this:

First consider the following values:

1 Minute = 60 Seconds
1 Hour = 3600 Seconds ( 60 * 60 )
1 Day = 86400 Second ( 24 * 3600 )

1. First divide the input by 86400, if you you can get a number greater than 0 , this is the number of days. 2.Again divide the remained number you get from the first calculation by 3600, this will give you the number of hours
2. Then divide the remainder of your second calculation by 60 which is the number of Minutes
3. Finally the remained number from your third calculation is the number of seconds

the code snippet is as follows:

int input=500000;
int numberOfDays;
int numberOfHours;
int numberOfMinutes;
int numberOfSeconds;

numberOfDays = input / 86400;
numberOfHours = (input % 86400 ) / 3600 ;
numberOfMinutes = ((input % 86400 ) % 3600 ) / 60 
numberOfSeconds = ((input % 86400 ) % 3600 ) % 60  ;

I hope to be helpful to you.

Here is the approach I use: http://thaiat.github.io/blog/2014/02/26/angularjs-and-requirejs-for-very-large-applications/

The page shows a possible implementation of AngularJS + RequireJS, where the code is split by features and then component type.

If you are using Matplotlib and are trying to get good figures in a LaTeX document, save as an EPS. Specifically, try something like this after running the commands to plot the image:

plt.savefig('destination_path.eps', format='eps')

I have found that EPS files work best and the dpi parameter is what really makes them look good in a document.

To specify the orientation of the figure before saving, simply call the following before the plt.savefig call, but after creating the plot (assuming you have plotted using an axes with the name ax):

ax.view_init(elev=elevation_angle, azim=azimuthal_angle)

Where elevation_angle is a number (in degrees) specifying the polar angle (down from vertical z axis) and the azimuthal_angle specifies the azimuthal angle (around the z axis).

I find that it is easiest to determine these values by first plotting the image and then rotating it and watching the current values of the angles appear towards the bottom of the window just below the actual plot. Keep in mind that the x, y, z, positions appear by default, but they are replaced with the two angles when you start to click+drag+rotate the image.

There is nothing to identify. Interfaces only proscribe a method name and signature. If both interfaces have a method of exactly the same name and signature, the implementing class can implement both interface methods with a single concrete method.

However, if the semantic contracts of the two interface method are contradicting, you've pretty much lost; you cannot implement both interfaces in a single class then.

No I guess you cannot restore the databases from higher version to lower version , you can make data flow b/w them i,e you can scriptout. http://www.mssqltips.com/sqlservertip/2810/how-to-migrate-a-sql-server-database-to-a-lower-version/

I don't know why the first answer is the best one, I tried it and not working in fact, as @kalys.osmonov said, you can give text-align:center to header, but you have to make ul as inline-block rather than inline, and also you have to notice that text-align can be inherited which is not good to some degree, so the better way (not working below IE 9) is using margin and transform. Just remove float right and margin;0 auto from ul, like below:

#header ul {
   /* float: right; */
   /* margin: 0 auto; */
   display: inline-block;
   margin-left: 50%; /* From parent width */
   transform: translateX(-50%); /* use self width which can be unknown */
  -ms-transform: translateX(-50%); /* For IE9 */
}

This way can fix the problem that making dynamic width of ul center if you don't care IE8 etc.

That is the parent folder of bin which contains tomcat.exe file:

CATALINA_HOME='C:\Program Files\Apache Software Foundation\Tomcat 6.0'

CATALINA_BASE is the same as CATALINA_HOME.

char * Source = "Hello, world.";

char * ShallowCopy = Source;    

char * DeepCopy = new char(strlen(Source)+1);
strcpy(DeepCopy,Source);        

'ShallowCopy' points to the same location in memory as 'Source' does. 'DeepCopy' points to a different location in memory, but the contents are the same.

Go to your application, settings (basic tab) and add platform (website). Type your site url and done.

The whole file is an array and there are objects and other arrays (e.g. cars) in the whole array of the file.

As you say, the outermost layer of your JSON blob is an array. Therefore, your parser will return a JSONArray. You can then get JSONObjects from the array ...

  JSONArray a = (JSONArray) parser.parse(new FileReader("c:\\exer4-courses.json"));

  for (Object o : a)
  {
    JSONObject person = (JSONObject) o;

    String name = (String) person.get("name");
    System.out.println(name);

    String city = (String) person.get("city");
    System.out.println(city);

    String job = (String) person.get("job");
    System.out.println(job);

    JSONArray cars = (JSONArray) person.get("cars");

    for (Object c : cars)
    {
      System.out.println(c+"");
    }
  }

For reference, see "Example 1" on the json-simple decoding example page.

Short answer

mvn install

• adds all artifact (dependencies) specified in pom, to the local repository (from remote sources).

If there is an interface anywhere in the ThreadProvider hierarchy try putting the name of the Interface as the type of your service provider, eg. if you have say this structure:

public class ThreadProvider implements CustomInterface{
...
}

Then in your controller try this:

@Controller
public class ChiusuraController {

    @Autowired
    private CustomInterface chiusuraProvider;
}

The reason why this is happening is, in your first case when you DID NOT have ChiusuraProvider extend ThreadProvider Spring probably was underlying creating a CGLIB based proxy for you(to handle the @Transaction).

When you DID extend from ThreadProvider assuming that ThreadProvider extends some interface, Spring in that case creates a Java Dynamic Proxy based Proxy, which would appear to be an implementation of that interface instead of being of ChisuraProvider type.

If you absolutely need to use ChisuraProvider you can try AspectJ as an alternative or force CGLIB based proxy in the case with ThreadProvider also this way:

<aop:aspectj-autoproxy proxy-target-class="true"/>

Here is some more reference on this from the Spring Reference site: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/classic-aop-spring.html#classic-aop-pfb

Kotlin Solution

The base way to handle it in Kotlin is:

edittext.setOnEditorActionListener { _, actionId, _ ->
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        callback.invoke()
        true
    }
    false
}

Kotlin Extension

Use this to just call edittext.onDone{/*action*/} in your main code. Makes your code far more readable and maintainable

fun EditText.onDone(callback: () -> Unit) {
    setOnEditorActionListener { _, actionId, _ ->
        if (actionId == EditorInfo.IME_ACTION_DONE) {
            callback.invoke()
            true
        }
        false
    }
}

Don't forget to add these options to your edittext

<EditText ...
    android:imeOptions="actionDone"
    android:inputType="text"/>

If you need inputType="textMultiLine" support, read this post
