I think your issue may be in the url pattern. Changing

<servlet-mapping>
    <servlet-name>Register</servlet-name>
    <url-pattern>/Register</url-pattern>
</servlet-mapping>

and

<form action="/Register" method="post">

may fix your problem

Use data type LONGBLOB instead of BLOB in your database table.

String user = request.getParameter("uname");
out.println(user); 
String pass = request.getParameter("pass");
out.println(pass); 
Class.forName( "com.mysql.jdbc.Driver" );
Connection conn = DriverManager.getConnection( "jdbc:mysql://localhost:3306/rental","root","root" ) ;
out.println("hello");
Statement st = conn.createStatement();
String sql = "insert into login (user,pass) values('" + user + "','" + pass + "')";
st.executeUpdate(sql);

You opened a lot of connections and that's the issue. I think in your code, you did not close the opened connection.

A database bounce could temporarily solve, but will re-appear when you do consecutive execution. Also, it should be verified the number of concurrent connections to the database. If maximum DB processes parameter has been reached this is a common symptom.

Courtesy of this thread: https://community.oracle.com/thread/362226?tstart=-1

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

tl;dr

With JDBC 4.2 or later and java 8 or later:

myPreparedStatement.setObject( … , myLocalDate  )

…and…

myResultSet.getObject( … , LocalDate.class )

Details

The Answer by Vargas is good about mentioning java.time types but refers only to converting to java.sql.Date. No need to convert if your driver is updated.

java.time

The java.time framework is built into Java 8 and later. These classes supplant the old troublesome date-time classes such as java.util.Date, .Calendar, & java.text.SimpleDateFormat. The Joda-Time team also advises migration to java.time.

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

Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport and further adapted to Android in ThreeTenABP.

LocalDate

In java.time, the java.time.LocalDate class represents a date-only value without time-of-day and without time zone.

If using a JDBC driver compliant with JDBC 4.2 or later spec, no need to use the old java.sql.Date class. You can pass/fetch LocalDate objects directly to/from your database via PreparedStatement::setObject and ResultSet::getObject.

LocalDate localDate = LocalDate.now( ZoneId.of( "America/Montreal" ) );
myPreparedStatement.setObject( 1 , localDate  );

…and…

LocalDate localDate = myResultSet.getObject( 1 , LocalDate.class );

Before JDBC 4.2, convert

If your driver cannot handle the java.time types directly, fall back to converting to java.sql types. But minimize their use, with your business logic using only java.time types.

New methods have been added to the old classes for conversion to/from java.time types. For java.sql.Date see the valueOf and toLocalDate methods.

java.sql.Date sqlDate = java.sql.Date.valueOf( localDate );

…and…

LocalDate localDate = sqlDate.toLocalDate();

Placeholder value

Be wary of using 0000-00-00 as a placeholder value as shown in your Question’s code. Not all databases and other software can handle going back that far in time. I suggest using something like the commonly-used Unix/Posix epoch reference date of 1970, 1970-01-01.

LocalDate EPOCH_DATE = LocalDate.ofEpochDay( 0 ); // 1970-01-01 is day 0 in Epoch counting.

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.

As @TechSpellBound suggested remove the quotes around the ? signs. Then add a space character at the end of each row in your concatenated string. Otherwise the entire query will be sent as (using only part of it as an example) : .... WHERE bookings.booking_end < date ?OR bookings.booking_start > date ?GROUP BY ....

The ? and the OR needs to be seperated by a space character. Do it wherever needed in the query string.

I was getting same kinda error but after copying the ojdbc14.jar into lib folder, no more exception.(copy ojdbc14.jar from somewhere and paste it into lib folder inside WebContent.)

Append the line useUnicode=true&characterEncoding=UTF-8 to your jdbc url.

In your case the data is not being send using UTF-8 encoding.

This is not how SQL works:

INSERT INTO employee(hans,germany) values(?,?)

The values (hans,germany) should use column names (emp_name, emp_address). The values are provided by your program by using the Statement.setString(pos,value) methods. It is complaining because you said there were two parameters (the question marks) but didn't provide values.

You should be creating a PreparedStatement and then setting parameter values as in:

String insert= "INSERT INTO employee(emp_name,emp_address) values(?,?)";
PreparedStatement stmt = con.prepareStatement(insert);
stmt.setString(1,"hans");
stmt.setString(2,"germany");
stmt.execute();

One of the reason may be if any one of table column have an underscore(_) in its name . That is considered as invalid characters by the JDBC . Rename the column by a ALTER Command and change in your code SQL , that will fix .

We can use the CONCAT SQL function.

PreparedStatement pstmt = con.prepareStatement(
      "SELECT * FROM analysis WHERE notes like CONCAT( '%',?,'%')";
pstmt.setString(1, notes);
ResultSet rs = pstmt.executeQuery();

This works perfectly for my case.

@an0, thanks for the answer!
The only thing is autoreleasepool: 

func fixOrientation(img: UIImage) -> UIImage? {

    let result: UIImage?
    if img.imageOrientation == .up {
        result = img
    } else {

        result = autoreleasepool { () -> UIImage? in
            UIGraphicsBeginImageContextWithOptions(img.size, false, img.scale)
            let rect = CGRect(x: 0, y: 0, width: img.size.width, height: img.size.height)
            img.draw(in: rect)

            let normalizedImage = UIGraphicsGetImageFromCurrentImageContext()
            UIGraphicsEndImageContext()

            return normalizedImage
        }
    }

    return result
}

@Ali Shakiba your code needs some modification. Error part:

for (int i = 0; i < myArray.length; i++) {
     myStatement.setString(i, myArray[i][1]);
     myStatement.setString(i, myArray[i][2]);
}

Updated code:

String myArray[][] = {
    {"1-1", "1-2"},
    {"2-1", "2-2"},
    {"3-1", "3-2"}
};

StringBuffer mySql = new StringBuffer("insert into MyTable (col1, col2) values (?, ?)");

for (int i = 0; i < myArray.length - 1; i++) {
    mySql.append(", (?, ?)");
}

mysql.append(";"); //also add the terminator at the end of sql statement
myStatement = myConnection.prepareStatement(mySql.toString());

for (int i = 0; i < myArray.length; i++) {
    myStatement.setString((2 * i) + 1, myArray[i][1]);
    myStatement.setString((2 * i) + 2, myArray[i][2]);
}

myStatement.executeUpdate();

Another simple way would be:

Integer i = new Integer("10");

if (i != null)
    int ip = Integer.parseInt(i.toString());

The GCC FAQ has an entry on it:

The solution is to ensure that all virtual methods that are not pure are defined. Note that a destructor must be defined even if it is declared pure-virtual [class.dtor]/7.

Therefore, you need to provide a definition for the virtual destructor:

virtual ~CDasherModule()
{ };

class Main {
    public static void main(String args[]) throws Exception {
        ApplicationContext ac = new
          ClassPathXmlApplicationContext("context.xml", Main.class);
        DataSource dataSource = (DataSource) ac.getBean("dataSource");
// DataSource mysqlDataSource = (DataSource) ac.getBean("mysqlDataSource");

        JdbcTemplate jdbcTemplate = new JdbcTemplate(dataSource);

        String prasobhName = 
        jdbcTemplate.query(
           "select first_name from customer where last_name like ?",
            new PreparedStatementSetter() {
              public void setValues(PreparedStatement preparedStatement) throws
                SQLException {
                  preparedStatement.setString(1, "nair%");
              }
            }, 
            new ResultSetExtractor<Long>() {
              public Long extractData(ResultSet resultSet) throws SQLException,
                DataAccessException {
                  if (resultSet.next()) {
                      return resultSet.getLong(1);
                  }
                  return null;
              }
            }
        );
        System.out.println(machaceksName);
    }
}

You can add log4jdbc to your project. This adds logging of sql commands as they execute + a lot of other information.

http://code.google.com/p/log4jdbc/wiki/FAQ

This is an old question and json-simple (https://code.google.com/p/json-simple/) could be a good solution at that time, but please consider that project seems not to be active for a while !

I suggest the Gson which is now hosted at: https://github.com/google/gson

If performance is your issue you can have a look at some benchmarks http://blog.takipi.com/the-ultimate-json-library-json-simple-vs-gson-vs-jackson-vs-json/ which compare.

This guide says:

6.1.5 Sending JDBC NULL as an IN parameter

The setNull method allows a programmer to send a JDBC NULL (a generic SQL NULL) value to the database as an IN parameter. Note, however, that one must still specify the JDBC type of the parameter.

A JDBC NULL will also be sent to the database when a Java null value is passed to a setXXX method (if it takes Java objects as arguments). The method setObject, however, can take a null value only if the JDBC type is specified.

So yes they're equivalent.

It is a pity that substring is not implemented in a way that handles short strings – like in other languages e.g. Python.

Ok, we cannot change that and have to consider this edge case every time we use substr, instead of if-else clauses I would go for this shorter variant:

myText.substring(0, Math.min(6, myText.length()))

My workaround (JavaScript)

    var s1 = " SELECT "

 + "FROM   table t "

 + "  where t.field in ";

  var s3 = '(';

  for(var i =0;i<searchTerms.length;i++)
  {
    if(i+1 == searchTerms.length)
    {
     s3  = s3+'?)';
    }
    else
    {
        s3  = s3+'?, ' ;
    }
   }
    var query = s1+s3;

    var pstmt = connection.prepareStatement(query);

     for(var i =0;i<searchTerms.length;i++)
    {
        pstmt.setString(i+1, searchTerms[i]);
    }

SearchTerms is the array which contains your input/keys/fields etc

You will be more secure if you use SSH authentication than username/password authentication.

If you are using a Mac, SSH client authentication is integrated into the MacOS keychain. Once you have created an SSH key, type into your terminal:

ssh-add -K ~/.ssh/id_rsa

This will add the SSH private key to the MacOS keychain. The git client will use ssh when it connects to the remote server. As long as you have registered your ssh public key with the server, you will be fine.

try this

LocationManager service = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria criteria = new Criteria();
String provider = service.getBestProvider(criteria, false);
Location location = service.getLastKnownLocation(provider);
LatLng userLocation = new LatLng(location.getLatitude(),location.getLongitude());

According to this post this error message means:

Heap size is larger than your computer's physical memory.

Edit: Heap is not the only memory that is reserved, I suppose. At least there are other JVM settings like PermGenSpace that ask for the memory. With heap size 128M and a PermGenSpace of 64M you already fill the space available.

Why not downsize other memory settings to free up space for the heap?

It's unfortunately not so easy to do that. If you're trying to make some sort of text user interface, you may want to look into curses. If you want to display things like you normally would in a terminal, but want input like that, then you'll have to work with termios, which unfortunately appears to be poorly documented in Python. Neither of these options are that simple, though, unfortunately. Additionally, they do not work under Windows; if you need them to work under Windows, you'll have to use PDCurses as a replacement for curses or pywin32 rather than termios.

I was able to get this working decently. It prints out the hexadecimal representation of keys you type. As I said in the comments of your question, arrows are tricky; I think you'll agree.

import termios
import contextlib


@contextlib.contextmanager

    old_attrs = termios.tcgetattr(file.fileno())
    new_attrs = old_attrs[:]
    new_attrs[3] = new_attrs[3] & ~(termios.ECHO | termios.ICANON)
    try:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, new_attrs)
        yield
    finally:
        termios.tcsetattr(file.fileno(), termios.TCSADRAIN, old_attrs)


def main():
    print 'exit with ^C or ^D'
    with raw_mode(sys.stdin):
        try:
            while True:
                ch = sys.stdin.read(1)
                if not ch or ch == chr(4):
                    break
                print '%02x' % ord(ch),
        except (KeyboardInterrupt, EOFError):
            pass

Just did this on Solaris and ran into this identical problem where even "java -version" does not work. There is a reason that the 64 bit versions of the distro are WAY smaller than the 32-bit. It is indeed as stated above:

In other words, to get a fully working 64-bit installation, you must first run the 32-bit installation, and follow that up with a 64-bit installation if you have a 64bit capable machine...

So I ran the installer for the 32-bit:

sh jdk-6u131-solaris-sparc.sh

Then I ran the installer for the 64-bit:

sh jdk-6u131-solaris-sparcv9.sh

This gives me several java executables to choose from:

• $ find . -name java
• ./jdk1.6.0_131/db/demo/programs/scores/java
• ./jdk1.6.0_131/db/demo/programs/vtis/java
• ./jdk1.6.0_131/bin/java
• ./jdk1.6.0_131/bin/sparcv9/java
• ./jdk1.6.0_131/jre/bin/java
• ./jdk1.6.0_131/jre/bin/sparcv9/java

The sparcv9 java's are the 64bit versions and they work with "-version" when installed alongside the 32bit JDK.

• ./jdk1.6.0_131/bin/sparcv9/java -version
• java version "1.6.0_131"
• Java(TM) SE Runtime Environment (build 1.6.0_131-b32)
• Java HotSpot(TM) 64-Bit Server VM (build 20.131-b32, mixed mode)

I use following code for get different result from condition That worked for me.

Select A.column, B.column
FROM TABLE1 A
INNER JOIN
TABLE2 B
ON A.Id = (case when (your condition) then b.Id else (something) END)

I might consider using a dict and re.sub for something like this:

import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
    return repldict[match.group(0)]

regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
    for line in fin:
        fout.write(regex.sub(replfunc,line))

This has a slight advantage to replace in that it is a bit more robust to overlapping matches.

Slightly different: Using Python 3 and print several variables in the same line:

print("~~Create new DB:",argv[5],"; with user:",argv[3],"; and Password:",argv[4]," ~~")

Q1.) Assuming process B tries to take ownership of the same mutex you locked in process A (you left that out of your pseudocode) then no, process B cannot access sharedResource while the mutex is locked since it will sit waiting to lock the mutex until it is released by process A. It will return from the mutex_lock() function when the mutex is locked (or when an error occurs!)

Q2.) In Process B, ensure you always lock the mutex, access the shared resource, and then unlock the mutex. Also, check the return code from the mutex_lock( pMutex ) routine to ensure that you actually own the mutex, and ONLY unlock the mutex if you have locked it. Do the same from process A.

Both processes should basically do the same thing when accessing the mutex.
lock() If the lock succeeds, then { access sharedResource unlock() }

Q3.) Yes, there are lots of diagrams: =) https://www.google.se/search?q=mutex+thread+process&rlz=1C1AFAB_enSE487SE487&um=1&ie=UTF-8&hl=en&tbm=isch&source=og&sa=N&tab=wi&ei=ErodUcSmKqf54QS6nYDoAw&biw=1200&bih=1730&sei=FbodUbPbB6mF4ATarIBQ

You can try this:

#!/bin/sh
nohup java -jar /web/server.jar &

The & symbol, switches the program to run in the background.

The nohup utility makes the command passed as an argument run in the background even after you log out.

You should be able to use the IF function for that. the syntax is =IF(condition, value_if_true, value_if_false). To add an extra column with only the non-reimbursed amounts, you would use something like:

=IF(B1="No", A1, 0)

and sum that. There's probably a way to include it in a single cell below the column as well, but off the top of my head I can't think of anything simple.

edit_text.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#ffffff" />
    <corners android:radius="5dp"/>
    <stroke android:width="2dip" android:color="@color/button_color_submit" />
</shape>

use here

<EditText
 -----
 ------
 android:background="@drawable/edit_text.xml"
/>

function printr($data)
{
   echo "<pre>";
      print_r($data);
   echo "</pre>";
}

And call your function on the page you need, don't forget to include the file where you put your function in for example: functions.php

include('functions.php');

printr($data);

Well, if you want the super easiest method, just put

<div class="left">left</div>
<div class="right">right</div>

.left {
    float: left;    
}

though you may need more than that depending on what other layout requirements you have.

As Kristian has pointed out, good control over z-values will often solve your problems.

If that does not work you can take a look at CSS Box Shadow Bottom Only on using overflow hidden to hide excess shadow.

I would also have in mind that the box-shadow property can accept a comma-separated list of shadows like this:

box-shadow: 0px 10px 5px #888, 0px -10px 5px #888;

This will give you some control over the "amount" of shadow in each direction.

Have a look at http://www.css3.info/preview/box-shadow/ for more information about box-shadow.

Hope this was what you were looking for!

What works for me on /FF and /Chrome:

body {

    position: fixed;
    width: 100%;
    height: 100%;

}

overflow: hidden just disables display of the scrollbars. (But you can put it in there if you like to).

There is one drawback I found: If you use this method on a page which you want only temporarily to stop scrolling, setting position: fixed will scroll it to the top. This is because position: fixed uses absolute positions which are currently set to 0/0.

This can be repaired e.g. with jQuery:

var lastTop;

function stopScrolling() {
    lastTop = $(window).scrollTop();      
    $('body').addClass( 'noscroll' )          
         .css( { top: -lastTop } )        
         ;            
}

function continueScrolling() {                    

    $('body').removeClass( 'noscroll' );      
    $(window).scrollTop( lastTop );       
}                                         

You can call the method like pump.getPumps(). By adding @classmethod decorator on the method. A class method receives the class as the implicit first argument, just like an instance method receives the instance.

class Pump:

def __init__(self):
    print ("init") # never prints

@classmethod
def getPumps(cls):
            # Open database connection
            # some stuff here that never gets executed because of error

So, simply call Pump.getPumps() .

In java, it is termed as static method.

This will be validated by compiler, so you won't mix up indices accidentally.

NSDictionary *stateStrings =
 @{
   @(MCSessionStateNotConnected) : @"MCSessionStateNotConnected",
   @(MCSessionStateConnecting) : @"MCSessionStateConnecting",
   @(MCSessionStateConnected) : @"MCSessionStateConnected",
  };
NSString *stateString = [stateStrings objectForKey:@(state)];

var stateStrings: [MCSessionState: String] = [
    .notConnected : "MCSessionState.notConnected",
    .connecting : "MCSessionState.connecting",
    .connected : "MCSessionState.connected"
]
var stateString = stateStrings[MCSessionState.Connected]

UPDATE: A more Swifty way is to extend the enum with CustomStringConvertible conformance. Also, this way the compiler will safeguard to implement every new addition to the underlying enum (whereas using arrays does not), as switch statements must be exhaustive.

extension MCSessionState: CustomStringConvertible {
    
    public var description: String {
        switch self {
        case .notConnected:
            return "MCSessionState.notConnected"
        case .connecting:
            return "MCSessionState.connecting"
        case .connected:
            return "MCSessionState.connected"
        @unknown default:
            return "Unknown"
        }
    }
}

// You can use it like this.
var stateString = MCSessionState.connected.description

// Or this.
var stateString = "\(MCSessionState.connected)"

Try this:

 $(function () {
     $('#row_dim').hide(); // this line you can avoid by adding #row_dim{display:none;} in your CSS
     $('#type').change(function () {
         $('#row_dim').hide();
         if (this.options[this.selectedIndex].value == 'parcel') {
             $('#row_dim').show();
         }
     });
 });

If you just want to output the first 5 elements, you should write something like:

<?php

  if (!empty ( $an_array ) ) {

    $min = min ( count ( $an_array ), 5 );

    $i = 0;

    foreach ($value in $an_array) {

      echo $value;
      $i++;
      if ($i == $min) break;

    }

  }

?>

If you want to write a function which returns part of the array, you should use array_slice:

<?php

  function GetElements( $an_array, $elements ) {
    return array_slice( $an_array, 0, $elements );
  }

?>

For a small enum like this, I find the most readable solution to be:

public enum Direction {

    NORTH {
        @Override
        public Direction getOppositeDirection() {
            return SOUTH;
        }
    }, 
    SOUTH {
        @Override
        public Direction getOppositeDirection() {
            return NORTH;
        }
    },
    EAST {
        @Override
        public Direction getOppositeDirection() {
            return WEST;
        }
    },
    WEST {
        @Override
        public Direction getOppositeDirection() {
            return EAST;
        }
    };


    public abstract Direction getOppositeDirection();

}

Extending on pkozlowski.opensource's answer and using javascript array's builtin filter method a prettified solution could be this:

.filter('weDontLike', function(){
    return function(items, name){
        return items.filter(function(item) {
            return item.name != name;
        });
    };
});

Here's the jsfiddle link.

More on Array filter here.

With:

global index_add_counter

You are not defining, just declaring so it's like saying there is a global index_add_counter variable elsewhere, and not create a global called index_add_counter. As you name don't exists, Python is telling you it can not import that name. So you need to simply remove the global keyword and initialize your variable:

index_add_counter = 0

Now you can import it with:

from app import index_add_counter

The construction:

global index_add_counter

is used inside modules' definitions to force the interpreter to look for that name in the modules' scope, not in the definition one:

index_add_counter = 0
def test():
  global index_add_counter # means: in this scope, use the global name
  print(index_add_counter)

As pointed out in comments, you cannot call cellForRowAtIndexPath inside heightForRowAtIndexPath.

What you can do is creating a template cell used to populate with your data and then compute its height. This cell doesn't participate to the table rendering, and it can be reused to calculate the height of each table cell.

Briefly, it consists of configuring the template cell with the data you want to display, make it resize accordingly to the content, and then read its height.

I have taken this code from a project I am working on - unfortunately it's in Objective C, I don't think you will have problems translating to swift

- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    static PostCommentCell *sizingCell = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken, ^{
        sizingCell = [self.tblComments dequeueReusableCellWithIdentifier:POST_COMMENT_CELL_IDENTIFIER];
    });

    sizingCell.comment = self.comments[indexPath.row];
    [sizingCell setNeedsLayout];
    [sizingCell layoutIfNeeded];

    CGSize size = [sizingCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize];
    return size.height;
}

I had the same issue trying to find text in files with powershell. I used the following - to stay as close to the Linux environment as possible.

Hopefully this helps somebody:

PowerShell:

PS) new-alias grep findstr
PS) ls -r *.txt | cat | grep "some random string"

Explanation:

ls       - lists all files
-r       - recursively (in all files and folders and subfolders)
*.txt    - only .txt files
|        - pipe the (ls) results to next command (cat)
cat      - show contents of files comming from (ls)
|        - pipe the (cat) results to next command (grep)
grep     - search contents from (cat) for "some random string" (alias to findstr)

Yes, this works as well:

PS) ls -r *.txt | cat | findstr "some random string"

You can also use this

$scope.persons = $filter('filter')($scope.persons , { id: ('!' + person.id) });

I had the same issue on OSX Mavericks, it turned out that Sophos anti-virus was blocking certain requests, once I uninstalled it the issue went away.

If you think that it might be caused by an extension one easy way to try and test this is to open chrome with the '--disable-extensions flag to see if it fixes the problem. If that doesn't fix it consider looking beyond the browser to see if any other application might be causing the problem, specifically security apps which can affect requests.

For Postgresql you can use PERFORM. PERFORM is only valid within PL/PgSQL procedure language.

DO $$ BEGIN
    PERFORM "saveUser"(3, 'asd','asd','asd','asd','asd');
END $$;

The suggestion from the postgres team:

HINT: If you want to discard the results of a SELECT, use PERFORM instead.

There is no "second property" -- when you say var obj = { ... }, the properties inside the braces are unordered. Even a 'for' loop walking through them might return them in different orders on different JavaScript implementations.

/** eworkyou **//

$('#navigation a').bind('click',function(e){

    var $this   = $(this);
    var prev    = current;

    current = $this.parent().index() + 1; //

    if (current == 1){
    $("#navigation a:eq(1)").unbind("click"); // 
    }
    if (current >= 2){
    $("#navigation a:eq(1)").bind("click"); // 
    }

The instructions in the official Python documentation worked for me: https://docs.python.org/2/using/windows.html#executing-scripts

1. Launch a command prompt.

2. Associate the correct file group with .py scripts:

   assoc .py=Python.File
   

Redirect all Python files to the new executable:

    ftype Python.File=C:\Path\to\pythonw.exe "%1" %*

The example shows how to associate the .py extension with the .pyw executable, but it works if you want to associate the .py extension with the Anaconda Python executable. You need administrative rights. The name "Python.File" could be anything, you just have to make sure is the same name in the ftype command. When you finish and before you try double-clicking the .py file, you must change the "Open with" in the file properties. The file type will be now ".py" and it is opened with the Anaconda python.exe.

mysql --help | grep /my.cnf | xargs ls

will tell you where my.cnf is located on Mac/Linux

ls: cannot access '/etc/my.cnf': No such file or directory
ls: cannot access '~/.my.cnf': No such file or directory
 /etc/mysql/my.cnf

In this case, it is in /etc/mysql/my.cnf

ls: /etc/my.cnf: No such file or directory
ls: /etc/mysql/my.cnf: No such file or directory
ls: ~/.my.cnf: No such file or directory
/usr/local/etc/my.cnf

In this case, it is in /usr/local/etc/my.cnf

What you're doing is appending a "1" (the string) to your URL. If you want page 1.html link to page 2.html you need to take the 1 out of the string, add one to it, then reassemble the string.

Why not do something like this:

var url = 'http://mywebsite.com/1.html';
var pageNum = parseInt( url.split("/").pop(),10 );
var nextPage = 'http://mywebsite.com/'+(pageNum+1)+'.html';

nextPage will contain the url http://mywebsite.com/2.html in this case. Should be easy to put in a function if needed.

You could use the Chr(int) function

TSQL, Alternative using variable declaration. (it might improve Query's readability)

DECLARE @gapPeriod DATETIME = DATEADD(MONTH,-2,GETDATE()); --Period:Last 2 months.

SELECT 
        *
    FROM 
        FB as A
    WHERE
        A.Dte <= @gapPeriod;                               --only older records.

I'd like to add df.values.tolist(). (as long as you don't mind to get a column of lists rather than tuples)

import pandas as pd
import numpy as np

size = int(1e+07)
df = pd.DataFrame({'a': np.random.rand(size), 'b': np.random.rand(size)}) 

%timeit df.values.tolist()
1.47 s ± 38.9 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

%timeit list(zip(df.a,df.b))
1.92 s ± 131 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)

Do what google commands you to do! here: http://developer.android.com/resources/faq/framework.html#3

• Primitive Data Types
• Non-Persistent Objects
• Singleton class - my favorite :D
• A public static field/method
• A HashMap of WeakReferences to Objects
• Persistent Objects (Application Preferences, Files, contentProviders, SQLite DB)

If anyone wants to use purely Java configuration instead of xml configuration of hibernate, use this:

You can configure Hibernate without using persistence.xml at all in Spring like like this:

@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactoryBean()
{
Map<String, Object> properties = new Hashtable<>();
properties.put("javax.persistence.schema-generation.database.action",
"none");
HibernateJpaVendorAdapter adapter = new HibernateJpaVendorAdapter();
adapter.setDatabasePlatform("org.hibernate.dialect.MySQL5InnoDBDialect"); //you can change this if you have a different DB
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter(adapter);
factory.setDataSource(this.springJpaDataSource());
factory.setPackagesToScan("package name");
factory.setSharedCacheMode(SharedCacheMode.ENABLE_SELECTIVE);
factory.setValidationMode(ValidationMode.NONE);
factory.setJpaPropertyMap(properties);
return factory;
}

Since you are not using persistence.xml, you should create a bean that returns DataSource which you specify in the above method that sets the data source:

@Bean
public DataSource springJpaDataSource()
{
DriverManagerDataSource dataSource = new DriverManagerDataSource();
dataSource.setUrl("jdbc:mysql://localhost/SpringJpa");
dataSource.setUsername("tomcatUser");
dataSource.setPassword("password1234");
return dataSource;
}

Then you use @EnableTransactionManagement annotation over this configuration file. Now when you put that annotation, you have to create one last bean:

@Bean
public PlatformTransactionManager jpaTransactionManager()
{
return new JpaTransactionManager(
this.entityManagerFactoryBean().getObject());
}

Now, don't forget to use @Transactional Annotation over those method that deal with DB.

Lastly, don't forget to inject EntityManager in your repository (This repository class should have @Repository annotation over it).

Since the profiler is not yet out in Laravel 4, I've created this helper function to see the SQL being generated:

    public static function q($all = true) 
    {
        $queries = DB::getQueryLog();

        if($all == false) {
            $last_query = end($queries);
            return $last_query;
        }

        return $queries;
    }

NOTE: Set the $all flag to false if you only want the last SQL query.

I keep this sort of functions in a class called DBH.php (short for Database Helper) so I can call it from anywhere like this:

dd(DBH::q()); 

Here is the output I get:

In case you are wondering, I use Kint for the dd() formatting. http://raveren.github.io/kint/

If you want your script to return values, just do return [1,2,3] from a function wrapping your code but then you'd have to import your script from another script to even have any use for that information:

Return values (from a wrapping-function)

(again, this would have to be run by a separate Python script and be imported in order to even do any good):

import ...
def main():
    # calculate stuff
    return [1,2,3]

Exit codes as indicators

(This is generally just good for when you want to indicate to a governor what went wrong or simply the number of bugs/rows counted or w/e. Normally 0 is a good exit and >=1 is a bad exit but you could inter-prate them in any way you want to get data out of it)

import sys
# calculate and stuff
sys.exit(100)

And exit with a specific exit code depending on what you want that to tell your governor. I used exit codes when running script by a scheduling and monitoring environment to indicate what has happened.

(os._exit(100) also works, and is a bit more forceful)

Stdout as your relay

If not you'd have to use stdout to communicate with the outside world (like you've described). But that's generally a bad idea unless it's a parser executing your script and can catch whatever it is you're reporting to.

import sys
# calculate stuff
sys.stdout.write('Bugs: 5|Other: 10\n')
sys.stdout.flush()
sys.exit(0)

Are you running your script in a controlled scheduling environment then exit codes are the best way to go.

Files as conveyors

There's also the option to simply write information to a file, and store the result there.

# calculate
with open('finish.txt', 'wb') as fh:
    fh.write(str(5)+'\n')

And pick up the value/result from there. You could even do it in a CSV format for others to read simplistically.

Sockets as conveyors

If none of the above work, you can also use network sockets locally *(unix sockets is a great way on nix systems). These are a bit more intricate and deserve their own post/answer. But editing to add it here as it's a good option to communicate between processes. Especially if they should run multiple tasks and return values.

Consider the figure enclosed in this other question. ebp-4 is your first local variable and, seen as a dword pointer, it is the address of a 32 bit integer that has to be cleared. Maybe your source starts with

Object x = null;

First type

 i

to enter the commit message then press ESC then type

 :wq

to save the commit message and to quit. Or type

 :q!

to quit without saving the message.

I was having the same problem, but using Long type. I changed for INT and it worked for me.

CREATE TABLE lists (
 id INT NOT NULL AUTO_INCREMENT,
 desc varchar(30),
 owner varchar(20),
 visibility boolean,
 PRIMARY KEY (id)
 );

Like nearly everyone else said, go to file -> Import Settings.

But if you don't see the "Import Settings" option under the file menu, you need to disable 2 plugins : IDE Settings Sync and Settings Repository

1. Set up your routes to accept data

{
    path: 'some-route',
    loadChildren: 
      () => import(
        './some-component/some-component.module'
      ).then(
        m => m.SomeComponentModule
      ),
    data: {
      key: 'value',
      ...
    },
}

2. Navigate to route:

From HTML:

<a [routerLink]=['/some-component', { key: 'value', ... }> ... </a>

Or from Typescript:

import {Router} from '@angular/router';

...

 this.router.navigate(
    [
       '/some-component',
       {
          key: 'value',
          ...
       }
    ]
 );

3. Get data from route

import {ActivatedRoute} from '@angular/router';

...

this.value = this.route.snapshot.params['key'];

I resolved it using this code to WebApiConfig.cs file

var json = config.Formatters.JsonFormatter;
json.SerializerSettings.PreserveReferencesHandling = Newtonsoft.Json.PreserveReferencesHandling.Objects; 
config.Formatters.Remove(config.Formatters.XmlFormatter);

There's also cratimeout by Martin Cracauer (written in C for Unix and Linux systems).

# cf. http://www.cons.org/cracauer/software.html
# usage: cratimeout timeout_in_msec cmd args
cratimeout 5000 sleep 1
cratimeout 5000 sleep 600
cratimeout 5000 tail -f /dev/null
cratimeout 5000 sh -c 'while sleep 1; do date; done'

The reason might be 127.0.0.1 is not linked to localhost. Check your 'C:\Windows\System32\drivers\etc\hosts' file. It should have a line like this:

# localhost name resolution is handled within DNS itself.
127.0.0.1 localhost

Are you running Android M? If so, this is because it's not enough to declare permissions in the manifest. For some permissions, you have to explicitly ask user in the runtime: http://developer.android.com/training/permissions/requesting.html

For the SQL Server 2017 (Developer Edition) installation, I did the following:

1. Open SQL Server Installation Center
2. Click on Installation
3. Click on New SQL Server stand-alone installation or add features to an existing installation
4. Browse to C:\SQLServer2017Media\Developer_ENU and click OK

I am only submitting this answer because people expressed concerns over browsers and maintaining the order of objects. I recognize that it is not the most efficient way to accomplish the goal.

Having said this, I broke the problem down into two functions for readability.

// The following function is used for each itertion in the function updateObjectsInArr
const newObjInInitialArr = function(initialArr, newObject) {
  let id = newObject.id;
  let newArr = [];
  for (let i = 0; i < initialArr.length; i++) {
    if (id === initialArr[i].id) {
      newArr.push(newObject);
    } else {
      newArr.push(initialArr[i]);
    }
  }
  return newArr;
};

const updateObjectsInArr = function(initialArr, newArr) {
    let finalUpdatedArr = initialArr;  
    for (let i = 0; i < newArr.length; i++) {
      finalUpdatedArr = newObjInInitialArr(finalUpdatedArr, newArr[i]);
    }

    return finalUpdatedArr
}

const revisedArr = updateObjectsInArr(arr1, arr2);

jsfiddle

You might want to try this example for version 2.6 of Python.

def my_print(text, begin, end):
    "Print text in UPPER between 'begin' and 'end' in lower."
    for obj in (text, begin, end):
        assert isinstance(obj, str), 'Argument of wrong type!'
    print begin.lower() + text.upper() + end.lower()

However, have you considered letting the function fail naturally instead?

The following methodology is about

• asking permissions dynamically ;
• showing a AlertDialog if the user denies any permission
• looping until the user accepts permission(s)

Create a "static" class for permissions methods

public class PermissionsUtil {
    public static final int PERMISSION_ALL = 1;

    public static boolean doesAppNeedPermissions(){
        return android.os.Build.VERSION.SDK_INT > Build.VERSION_CODES.LOLLIPOP_MR1;

        PackageInfo info = context.getPackageManager().getPackageInfo(
                context.getPackageName(), PackageManager.GET_PERMISSIONS);

        return info.requestedPermissions;
    }

    public static void askPermissions(Activity activity){
        if(doesAppNeedPermissions()) {
            try {
                String[] permissions = getPermissions(activity);

                if(!checkPermissions(activity, permissions)){
                    ActivityCompat.requestPermissions(activity, permissions,
                            PERMISSION_ALL);
                }
            } catch(Exception e) {
                e.printStackTrace();
            }
        }
    }

    public static boolean checkPermissions(Context context, String... permissions){

                if (ContextCompat.checkSelfPermission(context, permission) !=
                        PackageManager.PERMISSION_GRANTED) {
                    return false;

A combination of previous 2 answers did the trick. Thanks. A new class which inherits from Button. Note: updateImages() should be called before showing the button.

import javafx.event.EventHandler;
import javafx.scene.control.Button;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;

public class ImageButton extends Button {

    public void updateImages(final Image selected, final Image unselected) {
        final ImageView iv = new ImageView(selected);
        this.getChildren().add(iv);

        iv.setOnMousePressed(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(unselected);
            }
        });
        iv.setOnMouseReleased(new EventHandler<MouseEvent>() {
            public void handle(MouseEvent evt) {
                iv.setImage(selected);
            }
        });

        super.setGraphic(iv);
    }
}

you can use code below in layout

The most upvoted answer above is weird in a way that it simply clears the Clipboard and then gets the content (which is then empty). One could clear the clipboard to be sure that some clipboard content type like "formated text" does not "cover" your plain text content you want to save in the clipboard.

The following piece of code replaces all newlines in the clipboard by spaces, then removes all double spaces and finally saves the content back to the clipboard:

import win32clipboard

win32clipboard.OpenClipboard()
c = win32clipboard.GetClipboardData()
win32clipboard.EmptyClipboard()
c = c.replace('\n', ' ')
c = c.replace('\r', ' ')
while c.find('  ') != -1:
    c = c.replace('  ', ' ')
win32clipboard.SetClipboardText(c)
win32clipboard.CloseClipboard()

/** * Scroll management */ $(document).ready(function () {

// Define the menu we are working with
var menu = $('.navbar.navbar-default.navbar-inverse');

// Get the menus current offset
var origOffsetY = menu.offset().top;

/**
 * scroll
 * Perform our menu mod
 */
function scroll() {

    // Check the menus offset. 
    if ($(window).scrollTop() >= origOffsetY) {

        //If it is indeed beyond the offset, affix it to the top.
        $(menu).addClass('navbar-fixed-top');

    } else {

        // Otherwise, un affix it.
        $(menu).removeClass('navbar-fixed-top');

    }
}

// Anytime the document is scrolled act on it
document.onscroll = scroll;

});

This pointed me in the right direction, but I have a DB that originated in MSSQL 2000 and is still using the ntext data type for the column I was replacing on. When you try to run REPLACE on that type you get this error:

Argument data type ntext is invalid for argument 1 of replace function.

The simplest fix, if your column data fits within nvarchar, is to cast the column during replace. Borrowing the code from the accepted answer:

UPDATE YourTable
SET Column1 = REPLACE(cast(Column1 as nvarchar(max)),'a','b')
WHERE Column1 LIKE '%a%'

This worked perfectly for me. Thanks to this forum post I found for the fix. Hopefully this helps someone else!

I had a similar issue that was resolved by unchecking the option in java advanced security for "Use SSL 2.0 compatible ClientHello format.

For me a simple

exit

works. This is from within the screen session.

You need to encode Unicode explicitly before writing to a file, otherwise Python does it for you with the default ASCII codec.

Pick an encoding and stick with it:

f.write(printinfo.encode('utf8') + '\n')

or use io.open() to create a file object that'll encode for you as you write to the file:

import io

f = io.open(filename, 'w', encoding='utf8')

You may want to read:

• The Python Unicode HOWTO

• Pragmatic Unicode by Ned Batchelder

• The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky

before continuing.

It depends on what the integer is supposed to encode. You could convert the date to a number of milliseconds from some previous time. People often do this affixed to 12:00 am January 1 1970, or 1900, etc., and measure time as an integer number of milliseconds from that point. The datetime module (or others like it) will have functions that do this for you: for example, you can use int(datetime.datetime.utcnow().timestamp()).

If you want to semantically encode the year, month, and day, one way to do it is to multiply those components by order-of-magnitude values large enough to juxtapose them within the integer digits:

2012-06-13 --> 20120613 = 10,000 * (2012) + 100 * (6) + 1*(13)

def to_integer(dt_time):
    return 10000*dt_time.year + 100*dt_time.month + dt_time.day

E.g.

In [1]: import datetime

In [2]: %cpaste
Pasting code; enter '--' alone on the line to stop or use Ctrl-D.
:def to_integer(dt_time):
:    return 10000*dt_time.year + 100*dt_time.month + dt_time.day
:    # Or take the appropriate chars from a string date representation.
:--

In [3]: to_integer(datetime.date(2012, 6, 13))
Out[3]: 20120613

If you also want minutes and seconds, then just include further orders of magnitude as needed to display the digits.

I've encountered this second method very often in legacy systems, especially systems that pull date-based data out of legacy SQL databases.

It is very bad. You end up writing a lot of hacky code for aligning dates, computing month or day offsets as they would appear in the integer format (e.g. resetting the month back to 1 as you pass December, then incrementing the year value), and boiler plate for converting to and from the integer format all over.

Unless such a convention lives in a deep, low-level, and thoroughly tested section of the API you're working on, such that everyone who ever consumes the data really can count on this integer representation and all of its helper functions, then you end up with lots of people re-writing basic date-handling routines all over the place.

It's generally much better to leave the value in a date context, like datetime.date, for as long as you possibly can, so that the operations upon it are expressed in a natural, date-based context, and not some lone developer's personal hack into an integer.

The Qt documentations has an Image Viewer example which demonstrates handling resizing images inside a QLabel. The basic idea is to use QScrollArea as a container for the QLabel and if needed use label.setScaledContents(bool) and scrollarea.setWidgetResizable(bool) to fill available space and/or ensure QLabel inside is resizable. Additionally, to resize QLabel while honoring aspect ratio use:

label.setPixmap(pixmap.scaled(width, height, Qt::KeepAspectRatio, Qt::FastTransformation));

The width and height can be set based on scrollarea.width() and scrollarea.height(). In this way there is no need to subclass QLabel.

Because % is only defined for integer types. That's the modulus operator.

5.6.2 of the standard:

The operands of * and / shall have arithmetic or enumeration type; the operands of % shall have integral or enumeration type. [...]

As Oli pointed out, you can use fmod(). Don't forget to include math.h.

try this

 private void Form1_Load(object sender, EventArgs e)
    {
        notifyIcon1.BalloonTipText = "Application Minimized.";
        notifyIcon1.BalloonTipTitle = "test";
    }

    private void Form1_Resize(object sender, EventArgs e)
    {
        if (WindowState == FormWindowState.Minimized)
        {
            ShowInTaskbar = false;
            notifyIcon1.Visible = true;
            notifyIcon1.ShowBalloonTip(1000);
        }
    }

    private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
    {
        ShowInTaskbar = true;
        notifyIcon1.Visible = false;
        WindowState = FormWindowState.Normal;
    }

DataTable.Clone() should do the trick.

DataTable newTable = originalTable.Clone();

To answer your question: no, it's not possible to have multiple versions of IE (if that is what you meant) installed in a 'normal' way (i.e. not a hack, a sandbox or a VM etc). It's perfectly ok to have multiple browsers of different types installed on the same machine, such as IE8, Firefox 3 and Chrome all at once.

SandboxIE should allow you to install multiple versions of IE side-by-side (as well as other software), and this is less hassle than going down the virtual machine route.

However, from a QA point of view I'd strongly recommend installing different versions on different machines as the best option from a testing point of view. This will give you the most realistic testing environment. If you don't have the hardware for that, then virtual machines are the next best option as mentioned in some of the other answers.

If you don't know the row number, but do know some values then you can use subset

x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

subset(x, A ==5 & B==4.25 & C==4.5)

With the HTML5 "side-specs" no need to hack javascript anymore with setTimeout(), setInterval(), etc.

HTML5 & Friends introduces the javascript Web Workers specification. It is an API for running scripts asynchronously and independently.

Links to the specification and a tutorial.

def player(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over: 
        computer(game_over)  #We are only going to do this if check_winner comes back as False

def check_winner(): 
    check something
    #here needs to be an if / then statement deciding if the game is over, return True if over, false if not
    if score == 100:
        return True
    else:
        return False

def computer(game_over):
    do something here
    game_over = check_winner() #Here we tell check_winner to run and tell us what game_over should be, either true or false
    if not game_over:
        player(game_over) #We are only going to do this if check_winner comes back as False

game_over = False   #We need a variable to hold wether the game is over or not, we'll start it out being false.
player(game_over)   #Start your loops, sending in the status of game_over

Above is a pretty simple example... I made up a statement for check_winner using score = 100 to denote the game being over.

You will want to use similar method of passing score into check_winner, using game_over = check_winner(score). Then you can create a score at the beginning of your program and pass it through to computer and player just like game_over is being handled.

I am using searchform.php and search.php files as already mentioned, but here I provide the actual code.

Creating a Search Page codex page helps here and #Creating_a_Search_Page_Template shows the search query.

In my case I pass the $search_query arguments to the WP_Query Class (which can determine if is search query!). I then run The Loop to display the post information I want to, which in my case is the the_permalink and the_title.

Search box form:

<form class="search" method="get" action="<?php echo home_url(); ?>" role="search">
  <input type="search" class="search-field" placeholder="<?php echo esc_attr_x( 'Search …', 'placeholder' ) ?>" value="<?php echo get_search_query() ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'label' ) ?>" />
  <button type="submit" role="button" class="btn btn-default right"/><span class="glyphicon glyphicon-search white"></span></button>
</form>

search.php template file:

<?php
    global $query_string;
    $query_args = explode("&", $query_string);
    $search_query = array();

    foreach($query_args as $key => $string) {
      $query_split = explode("=", $string);
      $search_query[$query_split[0]] = urldecode($query_split[1]);
    } // foreach

    $the_query = new WP_Query($search_query);
    if ( $the_query->have_posts() ) : 
    ?>
    <!-- the loop -->

    <ul>    
    <?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
        <li>
            <a href="<?php the_permalink(); ?>"><?php the_title(); ?></a>
        </li>   
    <?php endwhile; ?>
    </ul>
    <!-- end of the loop -->

    <?php wp_reset_postdata(); ?>

<?php else : ?>
    <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

The issue I was facing was I have a project that is dependent on a library project. In order to build I was following these steps:

msbuild.exe myproject.vbproj /T:Rebuild
msbuild.exe myproject.vbproj /T:Package

That of course meant I was missing my library's dll files in bin and most importantly in the package zip file. I found this works perfectly:

msbuild.exe myproject.vbproj /T:Rebuild;Package

I have no idea why this work or why it didn't in the first place. But hope that helps.

 <html>
<head>
    <title>Print</title>
    <script type="text/javascript">
window.print();
document.margin='none';
</script>
</head>
<body>
  <p>hello</p>
  <p>hi</p>

//place it in a script file or in the script tag.

This will remove all the margins and you won't be able to see the headers and footers.

I know you've found a solution to your question, I just wanted to recommend that maybe you look at the following more extensive jQuery plugin for International Number Formats:

International Number Formatter

Arbitrary Indentation of any Option

If you just want to indent random, arbitrary <option /> elements, you can use  , which has the greatest cross-browser compatibility of the solutions posted here...

.optionGroup {
  font-weight: bold;
  font-style: italic;
}

<select>
    <option class="optionGroup" selected disabled>Choose one</option>
    <option value="sydney" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Sydney</option>
    <option value="melbourne" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Melbourne</option>
    <option value="cromwell" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Cromwell</option>
    <option value="queenstown" class="optionChild">&nbsp;&nbsp;&nbsp;&nbsp;Queenstown</option>
</select>

Ordered Indentation of Options

But if you have some sorted, ordered structure to your data, then it is recommended that you use the <optgroup/> syntax....

The HTML element creates a grouping of options within a element. (Source: MDN Web Docs: <optgroup>)

<select>
    <optgroup label="Australia" default selected>
        <option value="sydney">Sydney</option>
        <option value="melbourne">Melbourne</option>
    </optgroup>
    <optgroup label="United Kingdom">
        <option value="london">London</option>
        <option value="glasgow">Glasgow</option>
    </optgroup>
</select>

Unfortunately, only one <optgroup /> level is allowed and currently supported by browsers today. (Source: w3.org.) Personally, I would consider that part of the spec broken, but you can always extend to third, fourth, etc., levels of indentation with using the   trick up above.

Try this

Dim app As Excel.Application = Nothing
Dim Active_Cell As Excel.Range = Nothing

Try
            app = CType(Marshal.GetActiveObject("Excel.Application"), Excel.Application)
 Active_Cell = app.ActiveCell

Catch ex As Exception
            MsgBox(ex.Message)
            Exit Sub
        End Try

'             .address will return the cell reference :)

if (capital.touched && capital != undefined && capital.length < 1 ) { 
//capital does exists
}

This means we are not able to instantiate ES transportClient and throw this exception. There are couple of possibilities that cause this issue.

• Cluster name is incorrect. So open ES_HOME_DIR/config/elasticserach.yml file and check the cluster name value OR use this command: curl -XGET 'http://localhost:9200/_nodes'
• Verify port 9200 is http port but elasticsearch service is using tcp port 9300 [by default]. So verify that the port is not blocked.

• Authentication issue: set the header in transportClient's context for authentication:

  client.threadPool().getThreadContext()
    .putHeader("Authorization", "Basic " + encodeBase64String(basicHeader.getBytes()));
  

If you are still facing this issue then add the following property:

put("client.transport.ignore_cluster_name", true)

The below basic code is working fine for me:

Settings settings = Settings.builder()
            .put("cluster.name", "my-application").put("client.transport.sniff", true).put("client.transport.ignore_cluster_name", false).build();
    TransportClient client = new PreBuiltTransportClient(settings).addTransportAddress(new InetSocketTransportAddress(InetAddress.getByName("127.0.0.1"), 9300));

Although, maybe this should be posted on Super User.

This isn't the direct answer to your question, but since you seem to just want to disassemble the binary, perhaps you could just use objdump:

objdump -d program

This should give you its dissassembly. You can add -S if you want it source-annotated.

Transforming object to array with plain JavaScript's(ECMAScript-2016) Object.values:

var obj = {_x000D_
    22: {name:"John", id:22, friends:[5,31,55], works:{books:[], films:[]}},_x000D_
    12: {name:"Ivan", id:12, friends:[2,44,12], works:{books:[], films:[]}}_x000D_
}_x000D_
_x000D_
var values = Object.values(obj)_x000D_
_x000D_
console.log(values);

If you also want to keep the keys use Object.entries and Array#map like this:

var obj = {_x000D_
    22: {name:"John", id:22, friends:[5,31,55], works:{books:[], films:[]}},_x000D_
    12: {name:"Ivan", id:12, friends:[2,44,12], works:{books:[], films:[]}}_x000D_
}_x000D_
_x000D_
var values = Object.entries(obj).map(([k, v]) => ({[k]: v}))_x000D_
_x000D_
console.log(values);

$integer = 93;
$stringedInt = $integer.'';

is faster than

$integer = 93;
$stringedInt = $integer."";

What's the difference between "include" and "require" in Ruby?

Answer:

The include and require methods do very different things.

The require method does what include does in most other programming languages: run another file. It also tracks what you've required in the past and won't require the same file twice. To run another file without this added functionality, you can use the load method.

The include method takes all the methods from another module and includes them into the current module. This is a language-level thing as opposed to a file-level thing as with require. The include method is the primary way to "extend" classes with other modules (usually referred to as mix-ins). For example, if your class defines the method "each", you can include the mixin module Enumerable and it can act as a collection. This can be confusing as the include verb is used very differently in other languages.

Source

So if you just want to use a module, rather than extend it or do a mix-in, then you'll want to use require.

Oddly enough, Ruby's require is analogous to C's include, while Ruby's include is almost nothing like C's include.

In Oracle database we can achieve like this.

CREATE TABLE Student(
  StudentID Number(38, 0) not null,
  DepartmentID Number(38, 0) not null,
  PRIMARY KEY (StudentID, DepartmentID)
);

You cannot set cookies for another domain. Allowing this would present an enormous security flaw.

You need to get b.com to set the cookie. If a.com redirect the user to b.com/setcookie.php?c=value

The setcookie script could contain the following to set the cookie and redirect to the correct page on b.com

<?php
    setcookie('a', $_GET['c']);
    header("Location: b.com/landingpage.php");
?>

The Replace operator means Replace something with something else; do not be confused with removal functionality.

Also you should send the result processed by the operator to a variable or to another operator. Neither .Replace(), nor -replace modifies the original variable.

To remove all spaces, use 'Replace any space symbol with empty string'

$string = $string -replace '\s',''

To remove all spaces at the beginning and end of the line, and replace all double-and-more-spaces or tab symbols to spacebar symbol, use

$string = $string -replace '(^\s+|\s+$)','' -replace '\s+',' '

or the more native System.String method

$string = $string.Trim()

Regexp is preferred, because ' ' means only 'spacebar' symbol, and '\s' means 'spacebar, tab and other space symbols'. Note that $string.Replace() does 'Normal' replace, and $string -replace does RegEx replace, which is more heavy but more functional.

Note that RegEx have some special symbols like dot (.), braces ([]()), slashes (\), hats (^), mathematical signs (+-) or dollar signs ($) that need do be escaped. ( 'my.space.com' -replace '\.','-' => 'my-space-com'. A dollar sign with a number (ex $1) must be used on a right part with care

'2033' -replace '(\d+)',$( 'Data: $1')
Data: 2033

UPDATE: You can also use $str = $str.Trim(), along with TrimEnd() and TrimStart(). Read more at System.String MSDN page.

Observe that the interface name and the MAC address are the first and last fields on a line with no leading whitespace.

If one of the indented lines contains inet addr: the latest interface name and MAC address should be printed.

ifconfig -a |
awk '/^[a-z]/ { iface=$1; mac=$NF; next }
    /inet addr:/ { print iface, mac }'

Note that multiple interfaces could meet your criteria. Then, the script will print multiple lines. (You can add ; exit just before the final closing brace if you always only want to print the first match.)

What about this? I never found this patter around but I was just trying to exclude one or more properties without the need of creating an extra object. This seems to do the job but there are some side effects I'm not able to see. For sure is not very readable.

const postData = {
   token: 'secret-token',
   publicKey: 'public is safe',
   somethingElse: true,
};

const a = {
   ...(({token, ...rest} = postData) => (rest))(),
}

/**
a: {
   publicKey: 'public is safe',
   somethingElse: true,
}
*/

Consider the following code:

error_reporting(E_STRICT);
class test {
    function test_arr(&$a) {
        var_dump($a);
    }
    function get_arr() {
        return array(1, 2);
    }
}

$t = new test;
$t->test_arr($t->get_arr());

This will generate the following output:

Strict Standards: Only variables should be passed by reference in `test.php` on line 14
array(2) {
  [0]=>
  int(1)
  [1]=>
  int(2)
}

The reason? The test::get_arr() method is not a variable and under strict mode this will generate a warning. This behavior is extremely non-intuitive as the get_arr() method returns an array value.

To get around this error in strict mode, either change the signature of the method so it doesn't use a reference:

function test_arr($a) {
    var_dump($a);
}

Since you can't change the signature of array_shift you can also use an intermediate variable:

$inter = get_arr();
$el = array_shift($inter);

On 32-bit machine sizeof pointer is 32 bits ( 4 bytes), while on 64 bit machine it's 8 byte. Regardless of what data type they are pointing to, they have fixed size.

You have to first convert your object literal to a Prototype Hash:

// Store your object literal
var obj = {foo: 1, bar: 2, barobj: {75: true, 76: false, 85: true}}

// Iterate like so.  The $H() construct creates a prototype-extended Hash.
$H(obj).each(function(pair){
  alert(pair.key);
  alert(pair.value);
});

I was able to resolve this issue by performing a Gradle sync

To do this:

1. In project view, right click the root (in my example below, "JamsMusicPlayer"

2. Click "Synchronize {ProjectName}"

3. Once this completes, you should see a module in your "Run" dialog

A simplier option is to just capture the digits and replace them.

const name = 'preceding_text_0_following_text';_x000D_
const matcher = /(\d+)/;_x000D_
_x000D_
// Replace with whatever you would like_x000D_
const newName = name.replace(matcher, 'NEW_STUFF');_x000D_
console.log("Full replace", newName);_x000D_
_x000D_
// Perform work on the match and replace using a function_x000D_
// In this case increment it using an arrow function_x000D_
const incrementedName = name.replace(matcher, (match) => ++match);_x000D_
console.log("Increment", incrementedName);

In your case it should be:

Select convert(datetime,convert(varchar(10),GRADUATION_DATE,120)) as
'GRADUATION_DATE' from mydb

i think the most proper way is to use the same piece of code angular use when doing a "get" request using you $httpParamSerializer will have to inject it to your controller so you can simply do the following without having to use Jquery at all , $http.post(url,$httpParamSerializer({param:val}))

app.controller('ctrl',function($scope,$http,$httpParamSerializer){
  $http.post(url,$httpParamSerializer({param:val,secondParam:secondVal}));
}

Quick and dirty method to determine if Maven is using desired settings.xml would be invalidate its xml and run some safe maven command that requires settings.xml.

If it reads this settings.xml then Maven reports an error: "Error reading settings.xml..."

It is unfortunately easy to program in PHP in a way that consumes memory faster than you realise. Copying strings, arrays and objects instead of using references will do it, though PHP 5 is supposed to do this more automatically than in PHP 4. But dealing with your data set in entirety over several steps is also wasteful compared to processing the smallest logical unit at a time. The classic example is working with large resultsets from a database: most programmers fetch the entire resultset into an array and then loop over it one or more times with foreach(). It is much more memory efficient to use a while() loop to fetch and process one row at a time. The same thing applies to processing a file.

You can load the text file into a textfile Hive table and then insert the data from this table into your sequencefile.

Start with a tab delimited file:

% cat /tmp/input.txt
a       b
a2      b2

create a sequence file

hive> create table test_sq(k string, v string) stored as sequencefile;

try to load; as expected, this will fail:

hive> load data local inpath '/tmp/input.txt' into table test_sq;

But with this table:

hive> create table test_t(k string, v string) row format delimited fields terminated by '\t' stored as textfile;

The load works just fine:

hive> load data local inpath '/tmp/input.txt' into table test_t;
OK
hive> select * from test_t;
OK
a       b
a2      b2

Now load into the sequence table from the text table:

insert into table test_sq select * from test_t;

Can also do load/insert with overwrite to replace all.

Ignacio's answer is what you want. However, as someone also learning Python, let me try to dissect it for you... As mentioned, it is a list comprehension (covered in DiveIntoPython3, for example). Here are a few points:

[x[1] for x in L]

• Notice the []'s around the line of code. These are what define a list. This tells you that this code returns a list, so it's of the list type. Hence, this technique is called a "list comprehension."
• L is your original list. So you should define L = [(1,2),(2,3),(4,5),(3,4),(6,7),(6,7),(3,8)] prior to executing the above code.
• x is a variable that only exists in the comprehension - try to access x outside of the comprehension, or type type(x) after executing the above line and it will tell you NameError: name 'x' is not defined, whereas type(L) returns <class 'list'>.
• x[1] points to the second item in each of the tuples whereas x[0] would point to each of the first items.
• So this line of code literally reads "return the second item in a tuple for all tuples in list L."

It's tough to tell how much you attempted the problem prior to asking the question, but perhaps you just weren't familiar with comprehensions? I would spend some time reading through Chapter 3 of DiveIntoPython, or any resource on comprehensions. Good luck.

Dan Abramov's answer explains about the default exports and named exports.

Which to use?

Quoting David Herman: ECMAScript 6 favors the single/default export style, and gives the sweetest syntax to importing the default. Importing named exports can and even should be slightly less concise.

However, in TypeScript named export is favored because of refactoring. Example, if you default export a class and rename it, the class name will change only in that file and not in the other references, with named exports class name will be renamed in all the references. Named exports is also preferred for utilities.

Overall use whatever you prefer.

Additional

Default export is actually a named export with name default, so default export can be imported as:

import {default as Sample} from '../Sample.js';

Try the following steps:
1. Make sure you have the latest npm (npm install -g npm).
2. Add an exception to your antivirus to ignore the node_modules folder in your project.
3. $ rm -rf node_modules package-lock.json .
4. $ npm install

Try the following:

str1="2345";
int x=str1.charAt(2)-'0';
//here x=4;

if u subtract by char '0', the ASCII value needs not to be known.

I know this is an old post, but I wanted to add something for posterity. The simple way of handling the issue that you have is to make another table, of value to key.

ie. you have 2 tables that have the same value, one pointing one direction, one pointing the other.

function addValue(key, value)
    if (value == nil) then
        removeKey(key)
        return
    end
    _primaryTable[key] = value
    _secodaryTable[value] = key
end

function removeKey(key)
    local value = _primaryTable[key]
    if (value == nil) then
        return
    end
    _primaryTable[key] = nil
    _secondaryTable[value] = nil
end

function getValue(key)
    return _primaryTable[key]
end

function containsValue(value)
    return _secondaryTable[value] ~= nil
end

You can then query the new table to see if it has the key 'element'. This prevents the need to iterate through every value of the other table.

If it turns out that you can't actually use the 'element' as a key, because it's not a string for example, then add a checksum or tostring on it for example, and then use that as the key.

Why do you want to do this? If your tables are very large, the amount of time to iterate through every element will be significant, preventing you from doing it very often. The additional memory overhead will be relatively small, as it will be storing 2 pointers to the same object, rather than 2 copies of the same object. If your tables are very small, then it will matter much less, infact it may even be faster to iterate than to have another map lookup.

The wording of the question however strongly suggests that you have a large number of items to deal with.

Below code will give the output for number of days, by taking out the difference between two dates..

$str = "Jul 02 2013";
$str = strtotime(date("M d Y ")) - (strtotime($str));
echo floor($str/3600/24);

UPDATE: For Xcode 8.0+ you need to follow below Steps:

1. Download application from iTunes
2. Select downloaded app, right click show in finder
3. Copy .ipa file to Desktop, rename it to .zip file
4. Extract that .zip file and you will get directory with application name

5. Check that directory you will find app file in Payload folder, copy this app file

6. Go to ~/Library/Developer/CoreSimulator/Devices

FYI: Library folder is hidden by default in mac, you can see hidden file using below command.

defaults write com.apple.finder AppleShowAllFiles YES;
killall Finder /System/Library/CoreServices/Finder.app

Now here you'll see many directories with long hexadecimal names, these all are simulators.

To find your desired simulator, sort these directories using "Arranged By > Date Modified".

Select that simulator file and go to below location.

1. <HEXADECIMAL-SIMULATOR-STRING>/data/Containers/Bundle/Application/
2. Create new folder name with <download-app-name> and paste app file in that folder

3. Open Terminal and run below command to install this application

   xcrun simctl install booted <APP_FILE_PATH>
   

Example <APP_FILE_PATH> will be looks like below:

~/Library/Developer/CoreSimulator/Devices/<HEXADECIMAL-SIMULATOR-STRING>/data/Containers/Bundle/Application/<APP_NAME>

Using:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

...will show you the ctn_no value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
   WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

If you want to see the other column values associated with the duplicate, you'll want to use a self join:

SELECT x.*
  FROM YOUR_TABLE x
  JOIN (SELECT t.ctn_no
          FROM YOUR_TABLE t
      GROUP BY t.ctn_no
        HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no

You can try something like this:

List<Book> books = new ArrayList<Book>();

Collections.sort(books, new Comparator<Book>(){

  public int compare(Book o1, Book o2)
  {
     return o1.name.compareTo(o2.name);
  }
});

Just took a look over the mustache docs and they support "inverted sections" in which they state

they (inverted sections) will be rendered if the key doesn't exist, is false, or is an empty list

http://mustache.github.io/mustache.5.html#Inverted-Sections

{{#value}}
  value is true
{{/value}}
{{^value}}
  value is false
{{/value}}

The REPL makes it easy to learn APIs. Just run python, create an object and then ask for help:

$ python
>>> import re
>>> help(re.compile(r''))

at the command line shows, among other things:

search(...)

search(string[, pos[, endpos]]) --> match object or None. Scan through string looking for a match, and return a corresponding MatchObject instance. Return None if no position in the string matches.

so you can do

regex = re.compile(regex_txt, re.IGNORECASE)

match = regex.search(content)  # From your file reading code.
if match is not None:
  # use match

Incidentally,

regex_txt = "facebook.com"

has a . which matches any character, so re.compile("facebook.com").search("facebookkcom") is not None is true because . matches any character. Maybe

regex_txt = r"(?i)facebook\.com"

The \. matches a literal "." character instead of treating . as a special regular expression operator.

The r"..." bit means that the regular expression compiler gets the escape in \. instead of the python parser interpreting it.

The (?i) makes the regex case-insensitive like re.IGNORECASE but self-contained.

.md extension stands for Markdown, which Github uses, among others, to format those files.

If you need to perform in Microsoft Windows the equivalent of a symlink to /dev/null in Linux you would open and administrator's cmd and type:

For files:

mklink c:\path\to\file.ext NUL:

Or, for directories:

mklink /D c:\path\to\dir NUL:

This will keep the file/direcotry always at 0 byte, and still return success to every write attempt.

You should bear in mind that a-z, A-Z, 0-9, ., _ and - are not the only valid characters in the start of an email address.

Gmail, for example, lets you put a "+" sign in the address to "fake" a different email (e.g. [email protected] will also get email sent to [email protected]).

micky.o'[email protected] would not appreciate your code stopping them entering their address ... apostrophes are perfectly valid in email addresses.

The Closure "check" of a valid email address mentioned above is, as it states itself, quite naïve:

http://code.google.com/p/closure-library/source/browse/trunk/closure/goog/format/emailaddress.js#198

I recommend being very open in your client side code, and then much more heavyweight like sending an email with a link to really check that it's "valid" (as in - syntactically valid for their provider, and also not misspelled).

Something like this:

var pattern = /[^@]+@[-a-z\.]\.[a-z\.]{2,6}/

Bearing in mind that theoretically you can have two @ signs in an email address, and I haven't even included characters beyond latin1 in the domain names!

A programming language implementation is a system for executing computer programs.

There are two general approaches to programming language implementation:

• Interpretation: An interpreter takes as input a program in some language, and performs the actions written in that language on some machine.
• Compilation: A compiler takes as input a program in some language, and translates that program into some other language, which may serve as input to another interpreter or another compiler.

Python is an interpreted high-level programming language created by Guido van Rossum in 1991.

CPython is reference version of the Python computing language, which is written in C created by Guido van Rossum too.

unicode is meant to handle text. Text is a sequence of code points which may be bigger than a single byte. Text can be encoded in a specific encoding to represent the text as raw bytes(e.g. utf-8, latin-1...).

Note that unicode is not encoded! The internal representation used by python is an implementation detail, and you shouldn't care about it as long as it is able to represent the code points you want.

On the contrary str in Python 2 is a plain sequence of bytes. It does not represent text!

You can think of unicode as a general representation of some text, which can be encoded in many different ways into a sequence of binary data represented via str.

Note: In Python 3, unicode was renamed to str and there is a new bytes type for a plain sequence of bytes.

Some differences that you can see:

>>> len(u'à')  # a single code point
1
>>> len('à')   # by default utf-8 -> takes two bytes
2
>>> len(u'à'.encode('utf-8'))
2
>>> len(u'à'.encode('latin1'))  # in latin1 it takes one byte
1
>>> print u'à'.encode('utf-8')  # terminal encoding is utf-8
à
>>> print u'à'.encode('latin1') # it cannot understand the latin1 byte
?

Note that using str you have a lower-level control on the single bytes of a specific encoding representation, while using unicode you can only control at the code-point level. For example you can do:

>>> 'àèìòù'
'\xc3\xa0\xc3\xa8\xc3\xac\xc3\xb2\xc3\xb9'
>>> print 'àèìòù'.replace('\xa8', '')
à?ìòù

What before was valid UTF-8, isn't anymore. Using a unicode string you cannot operate in such a way that the resulting string isn't valid unicode text. You can remove a code point, replace a code point with a different code point etc. but you cannot mess with the internal representation.

Example:

<input type="button" value="Click me" id="myButton">
<script>
    var myButton = document.getElementById("myButton");
    var test = "zipzambam";
    myButton.onclick = function(eventObject) {
        if (!eventObject) {
            eventObject = window.event;
        }
        if (!eventObject.target) {
            eventObject.target = eventObject.srcElement;
        }
        alert(eventObject.target);
        alert(test);
    };
    (function(myMessage) {
        alert(myMessage);
    })("Hello");
</script>

i have alreay 2 situations where directives and services/factories didnt play well.

the scenario is that i have (had) a directive that has dependency injection of a service, and from the directive i ask the service to make an ajax call (with $http).

in the end, in both cases the ng-Repeat did not file at all, even when i gave the array an initial value.

i even tried to make a directive with a controller and an isolated-scope

only when i moved everything to a controller and it worked like magic.

You could use a pass statement:

if condition:
    pass

Python 2.x documentation

Python 3.x documentation

However I doubt you want to do this, unless you just need to put something in as a placeholder until you come back and write the actual code for the if statement.

If you have something like this:

if condition:        # condition in your case being `num2 == num5`
    pass
else:
    do_something()

You can in general change it to this:

if not condition:
    do_something()

But in this specific case you could (and should) do this:

if num2 != num5:        # != is the not-equal-to operator
    do_something()

Which model is the "best fitting model" depends on what you mean by "best". R has tools to help, but you need to provide the definition for "best" to choose between them. Consider the following example data and code:

x <- 1:10
y <- x + c(-0.5,0.5)

plot(x,y, xlim=c(0,11), ylim=c(-1,12))

fit1 <- lm( y~offset(x) -1 )
fit2 <- lm( y~x )
fit3 <- lm( y~poly(x,3) )
fit4 <- lm( y~poly(x,9) )
library(splines)
fit5 <- lm( y~ns(x, 3) )
fit6 <- lm( y~ns(x, 9) )

fit7 <- lm( y ~ x + cos(x*pi) )

xx <- seq(0,11, length.out=250)
lines(xx, predict(fit1, data.frame(x=xx)), col='blue')
lines(xx, predict(fit2, data.frame(x=xx)), col='green')
lines(xx, predict(fit3, data.frame(x=xx)), col='red')
lines(xx, predict(fit4, data.frame(x=xx)), col='purple')
lines(xx, predict(fit5, data.frame(x=xx)), col='orange')
lines(xx, predict(fit6, data.frame(x=xx)), col='grey')
lines(xx, predict(fit7, data.frame(x=xx)), col='black')

Which of those models is the best? arguments could be made for any of them (but I for one would not want to use the purple one for interpolation).

it's simple , and it's really worked for me .

run you wamp server => click right mouse button => and click on "put online"

then open your cmd as an administrateur , and pass in this commande word

ipconfig => and press enter

then lot of adresses show-up , then you have just to take the first one , it's look like this example: Adresse IPv4. . . . . . . . . . . . . .: 192.168.67.190 well done ! , that's the adresse, that you will use to cennecte to your wampserver in local.

Since originally writing this answer, a new specification has reached recommendation status thanks to the W3C. The Page Visibility API (on MDN) now allows us to more accurately detect when a page is hidden to the user.

document.addEventListener("visibilitychange", onchange);

Current browser support:

• Chrome 13+
• Internet Explorer 10+
• Firefox 10+
• Opera 12.10+ ^{[read notes]}

The following code falls back to the less reliable blur/focus method in incompatible browsers:

(function() {
  var hidden = "hidden";

  // Standards:
  if (hidden in document)
    document.addEventListener("visibilitychange", onchange);
  else if ((hidden = "mozHidden") in document)
    document.addEventListener("mozvisibilitychange", onchange);
  else if ((hidden = "webkitHidden") in document)
    document.addEventListener("webkitvisibilitychange", onchange);
  else if ((hidden = "msHidden") in document)
    document.addEventListener("msvisibilitychange", onchange);
  // IE 9 and lower:
  else if ("onfocusin" in document)
    document.onfocusin = document.onfocusout = onchange;
  // All others:
  else
    window.onpageshow = window.onpagehide
    = window.onfocus = window.onblur = onchange;

  function onchange (evt) {
    var v = "visible", h = "hidden",
        evtMap = {
          focus:v, focusin:v, pageshow:v, blur:h, focusout:h, pagehide:h
        };

    evt = evt || window.event;
    if (evt.type in evtMap)
      document.body.className = evtMap[evt.type];
    else
      document.body.className = this[hidden] ? "hidden" : "visible";
  }

  // set the initial state (but only if browser supports the Page Visibility API)
  if( document[hidden] !== undefined )
    onchange({type: document[hidden] ? "blur" : "focus"});
})();

onfocusin and onfocusout are required for IE 9 and lower, while all others make use of onfocus and onblur, except for iOS, which uses onpageshow and onpagehide.

Try this:

Open PgAdmin -> Files -> Open pgpass.conf

You would get the path of pgpass.conf at the bottom of the window. Go to that location and open this file, you can find your password there.

Reference

If the above does not work, you may consider trying this:

 1. edit pg_hba.conf to allow trust authorization temporarily
 2. Reload the config file (pg_ctl reload)
 3. Connect and issue ALTER ROLE / PASSWORD to set the new password
 4. edit pg_hba.conf again and restore the previous settings
 5. Reload the config file again

In case someone has this while trying to compile an Android project, there is an alternative Nullable implementation in android.support.annotation.Nullable. So take care which package you've referenced in your imports.

It means to interpret the string literally (that is, you cannot escape any characters within the string if you use the @ prefix). It enhances readability in cases where it can be used.

For example, if you were working with a UNC path, this:

@"\\servername\share\folder"

is nicer than this:

"\\\\servername\\share\\folder"

for(int i=validData.length-1; i>=0; i--){
  System.out.println(validData[i]);
 }

I'm surprised no one has mentioned using regular expressions via re.sub():

import re
print re.sub(r'([\"])',    r'\\\1', 'it\'s "this"')  # it's \"this\"
print re.sub(r"([\'])",    r'\\\1', 'it\'s "this"')  # it\'s "this"
print re.sub(r'([\" \'])', r'\\\1', 'it\'s "this"')  # it\'s\ \"this\"

Important things to note:

• In the search pattern, include \ as well as the character(s) you're looking for. You're going to be using \ to escape your characters, so you need to escape that as well.
• Put parentheses around the search pattern, e.g. ([\"]), so that the substitution pattern can use the found character when it adds \ in front of it. (That's what \1 does: uses the value of the first parenthesized group.)
• The r in front of r'([\"])' means it's a raw string. Raw strings use different rules for escaping backslashes. To write ([\"]) as a plain string, you'd need to double all the backslashes and write '([\\"])'. Raw strings are friendlier when you're writing regular expressions.
• In the substitution pattern, you need to escape \ to distinguish it from a backslash that precedes a substitution group, e.g. \1, hence r'\\\1'. To write that as a plain string, you'd need '\\\\\\1' — and nobody wants that.

November 2020 Update

I searched for the top NodeJS html parser libraries.

Because my use cases didn't require a library with many features, I could focus on stability and performance.

By stability I mean that I want the library to be used long enough by the community in order to find bugs and that it will be still maintained and that open issues will be closed.

Its hard to understand the future of an open source library, but I did a small summary based on the top 10 libraries in openbase.

I divided into 2 groups according to the last commit (and on each group the order is according to Github starts):

Last commit is in the last 6 months:

jsdom - Last commit: 3 Months, Open issues: 331, Github stars: 14.9K.

htmlparser2 - Last commit: 8 days, Open issues: 2, Github stars: 2.7K.

parse5 - Last commit: 2 Months, Open issues: 21, Github stars: 2.5K.

swagger-parser - Last commit: 2 Months, Open issues: 48, Github stars: 663.

html-parse-stringify - Last commit: 4 Months, Open issues: 3, Github stars: 215.

node-html-parser - Last commit: 7 days, Open issues: 15, Github stars: 205.

Last commit is 6 months and above:

cheerio - Last commit: 1 year, Open issues: 174, Github stars: 22.9K.

koa-bodyparser - Last commit: 6 months, Open issues: 9, Github stars: 1.1K.

sax-js - Last commit: 3 Years, Open issues: 65, Github stars: 941.

draftjs-to-html - Last commit: 1 Year, Open issues: 27, Github stars: 233.

I picked Node-html-parser because it seems quiet fast and very active at this moment.

(*) Openbase adds much more information regarding each library like the number of contributors (with +3 commits), weekly downloads, Monthly commits, Version etc'.

(**) The table above is a snapshot according to the specific time and date - I would check the reference again and as a first step check the level of recent activity and then dive into the smaller details.

if [ ! -z "$var" ] && [ -e "$var" ]; then
      # something ...

Here's one way that I found to do it. I don't know if there are better ways, or what the trade-offs are.

Container "tries to be as big as possible", according to https://flutter.io/layout/. Also, Container can take a decoration, which can be a BoxDecoration, which can have a color (which, is the background color).

Here's a sample that does indeed fill the screen with red, and puts "Hello, World!" into the center:

import 'package:flutter/material.dart';

void main() {
  runApp(new MyApp());
}

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return new Container(
      decoration: new BoxDecoration(color: Colors.red),
      child: new Center(
        child: new Text("Hello, World!"),
      ),
    );
  }
}

Note, the Container is returned by the MyApp build(). The Container has a decoration and a child, which is the centered text.

SET GLOBAL local_infile = true;

I mean I logged in first with the usual:

mysql -u user -p*

After that you can see the status with the command:

SHOW GLOBAL VARIABLES LIKE 'local_infile';

It should be ON. I will not be writing about security issued with loading local files into database here.

The only way that worked for me using code (not XML) is this one:

etPassword.setInputType(InputType.TYPE_TEXT_VARIATION_PASSWORD);
etPassword.setTransformationMethod(PasswordTransformationMethod.getInstance());

You can use this small library: https://github.com/ledfusion/php-rest-curl

Making a call is as simple as:

// GET
$result = RestCurl::get($URL, array('id' => 12345678));

// POST
$result = RestCurl::post($URL, array('name' => 'John'));

// PUT
$result = RestCurl::put($URL, array('$set' => array('lastName' => "Smith")));

// DELETE
$result = RestCurl::delete($URL); 

And for the $result variable:

• $result['status'] is the HTTP response code
• $result['data'] an array with the JSON response parsed
• $result['header'] a string with the response headers

Hope it helps

Here is a little combination of @Regexident Option 1 and @Garett answers, to get a powerful string cutter between a prefix and suffix, with MORE...ANDMORE words on it.

NSString *haystack = @"MOREvalue:hello World:valueANDMORE";
NSString *prefix = @"value:";
NSString *suffix = @":value";
NSRange prefixRange = [haystack rangeOfString:prefix];
NSRange suffixRange = [[haystack substringFromIndex:prefixRange.location+prefixRange.length] rangeOfString:suffix];
NSRange needleRange = NSMakeRange(prefixRange.location+prefix.length, suffixRange.location);
NSString *needle = [haystack substringWithRange:needleRange];
NSLog(@"needle: %@", needle);

As Ollie C mentioned, there is an active bug for the support library using returned values to onActivityResult when you are using nested fragments. I just hit it :-(.

See Fragment.onActivityResult not called when requestCode != 0.

change select2.css file

to

Try setting a custom CultureInfo for CurrentCulture and CurrentUICulture:

Globalization.CultureInfo customCulture = new Globalization.CultureInfo("en-US", true);

customCulture.DateTimeFormat.ShortDatePattern = "yyyy-MM-dd h:mm tt";

System.Threading.Thread.CurrentThread.CurrentCulture = customCulture;
System.Threading.Thread.CurrentThread.CurrentUICulture = customCulture;

DateTime newDate = System.Convert.ToDateTime(DateTime.Now.ToString("yyyy-MM-dd h:mm tt"));

The Answer by McDowell is correct one. However if you try other suggestion in few of the posts above.

HttpEntity responseEntity = httpResponse.getEntity();
if(responseEntity!=null) {
   response = EntityUtils.toString(responseEntity);
   S.O.P (response);
}

Then it will give you illegalStateException stating that content is already consumed.

If you are in a po-up and you want to access the opening window, use window.opener. The easiest would be if you could load JQuery in the parent window as well:

window.opener.$("#serverMsg").html // this uses JQuery in the parent window

or you could use plain old document.getElementById to get the element, and then extend it using the jquery in your child window. The following should work (I haven't tested it, though):

element = window.opener.document.getElementById("serverMsg");
element = $(element);

If you are in an iframe or frameset and want to access the parent frame, use window.parent instead of window.opener.

According to the Same Origin Policy, all this works effortlessly only if both the child and the parent window are in the same domain.

I use method 3 because it's the most understandable for others (whenever you see an <a> tag, you know it's a link) and when you are part of a team, you have to make simple things ;).

And finally I don't think it's useful and efficient to use JS simply to navigate to an other page.

My 2 cents on this error, even if not related to an export/import scenario:

when adding the mobile provisioning certificate (i.e. the PROV file), DO NOT drag the file from Finder to Keychain Access. Instead, just double click the PROV file within Finder, while keeping the Keychain Access application running somewhere.

I've actually seen my former provisioning item in Keychain (the one with yellow light) being substituted with a new, green one with same name and app ID. HTH

I make a (sub)folder named "hide", move the file I don't want committed to there. Then do my commit, ignoring complaint about the missing file. Then move the hidden file from hide back to ./

I know of no downside to this tactic.

Here is a simple one with callback and IE support:

function loadScript(url, callback) {

    var script = document.createElement("script")
    script.type = "text/javascript";

    if (script.readyState) { //IE
        script.onreadystatechange = function () {
            if (script.readyState == "loaded" || script.readyState == "complete") {
                script.onreadystatechange = null;
                callback();
            }
        };
    } else { //Others
        script.onload = function () {
            callback();
        };
    }

    script.src = url;
    document.getElementsByTagName("head")[0].appendChild(script);
}

loadScript("https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js", function () {

     //jQuery loaded
     console.log('jquery loaded');

});

Using sqlplus

sqlplus / as sysdba

run:

SELECT * 
FROM dba_users

Should you only want the usernames do the following:

SELECT username 
FROM dba_users

The first numbers of the credit card can be used to approximate the vendor:

• Visa: 49,44 or 47
• Visa electron: 42, 45, 48, 49
• MasterCard: 51
• Amex:34
• Diners: 30, 36, 38
• JCB: 35

The way I do, by using Delphi:

TheString to "escape":

TheString=" bla bla bla 'em some more apo:S 'em and so on ";

Solution:

StringReplace(TheString, #39,'\'+#39, [rfReplaceAll, rfIgnoreCase]);

Result:

TheString=" bla bla bla \'em some more apo:S \'em and so on ";

This function will replace all Char(39) with "\'" allowing you to insert or update text fields in MySQL without any problem.

Similar functions are found in all programming languages!

You must understand the difference between a class and an instance of that class. If you see a car on the street, you know immediately that it's a car even if you can't see which model or type. This is because you compare what you see with the class "car". The class contains which is similar to all cars. Think of it as a template or an idea.

At the same time, the car you see is an instance of the class "car" since it has all the properties which you expect: There is someone driving it, it has an engine, wheels.

So the class says "all cars have a color" and the instance says "this specific car is red".

In the OO world, you define the class and inside the class, you define a field of type Color. When the class is instantiated (when you create a specific instance), memory is reserved for the color and you can give this specific instance a color. Since these attributes are specific, they are non-static.

Static fields and methods are shared with all instances. They are for values which are specific to the class and not a specific instance. For methods, this usually are global helper methods (like Integer.parseInt()). For fields, it's usually constants (like car types, i.e. something where you have a limited set which doesn't change often).

To solve your problem, you need to instantiate an instance (create an object) of your class so the runtime can reserve memory for the instance (otherwise, different instances would overwrite each other which you don't want).

In your case, try this code as a starting block:

public static void main (String[] args)
{
    try
    {
        MyProgram7 obj = new MyProgram7 ();
        obj.run (args);
    }
    catch (Exception e)
    {
        e.printStackTrace ();
    }
}

// instance variables here

public void run (String[] args) throws Exception
{
    // put your code here
}

The new main() method creates an instance of the class it contains (sounds strange but since main() is created with the class instead of with the instance, it can do this) and then calls an instance method (run()).

FWIW, you probably want to look at F# instead of C# in the context of technical computing because F# is specifically designed for that purpose. However, I developed my own commercial plotting library because I was not satisfied with anything freely available on .NET.

Just in case you're using bootstrap 4, you can add px-0 (set left/right padding to 0) and mx-0 (set left/right margin to 0) CSS class to body tag, like below:

<body class="px-0; mx-0">
    <!--your body HTML-->
</body>

Good quote taken from a blog

The DOM component is "garbage collected", as is the JScript component, which means that if you create an object within either component, and then lose track of that object, it will eventually be cleaned up.

For example:

function makeABigObject() {
var bigArray = new Array(20000);
}

When you call that function, the JScript component creates an object (named bigArray) that is accessible within the function. As soon as the function returns, though, you "lose track" of bigArray because there's no way to refer to it anymore. Well, the JScript component realizes that you've lost track of it, and so bigArray is cleaned up--its memory is reclaimed. The same sort of thing works in the DOM component. If you say document.createElement('div'), or something similar, then the DOM component creates an object for you. Once you lose track of that object somehow, the DOM component will clean up the related.

There is a package random_word could implement this request very conveniently:

 $ pip install random-word

from random_word import RandomWords
r = RandomWords()

# Return a single random word
r.get_random_word()
# Return list of Random words
r.get_random_words()
# Return Word of the day
r.word_of_the_day()

Adding to @torvin's answer and as @Dave Huang mentioned in the comments if you have TextTrimming="CharacterEllipsis" enabled the application crashes when you hover over the ellipsis.

I tried other options mentioned in the thread about using a TextBox but it really doesn't seem to be the solution either as it doesn't show the 'ellipsis' and also if the text is too long to fit the container selecting the content of the textbox 'scrolls' internally which isn't a TextBlock behaviour.

I think the best solution is @torvin's answer but has the nasty crash when hovering over the ellipsis.

I know it isn't pretty, but subscribing/unsubscribing internally to unhandled exceptions and handling the exception was the only way I found of solving this problem, please share if somebody has a better solution :)

public class SelectableTextBlock : TextBlock
{
    static SelectableTextBlock()
    {
        FocusableProperty.OverrideMetadata(typeof(SelectableTextBlock), new FrameworkPropertyMetadata(true));
        TextEditorWrapper.RegisterCommandHandlers(typeof(SelectableTextBlock), true, true, true);

        // remove the focus rectangle around the control
        FocusVisualStyleProperty.OverrideMetadata(typeof(SelectableTextBlock), new FrameworkPropertyMetadata((object)null));
    }

    private readonly TextEditorWrapper _editor;

    public SelectableTextBlock()
    {
        _editor = TextEditorWrapper.CreateFor(this);

        this.Loaded += (sender, args) => {
            this.Dispatcher.UnhandledException -= Dispatcher_UnhandledException;
            this.Dispatcher.UnhandledException += Dispatcher_UnhandledException;
        };
        this.Unloaded += (sender, args) => {
            this.Dispatcher.UnhandledException -= Dispatcher_UnhandledException;
        };
    }

    private void Dispatcher_UnhandledException(object sender, DispatcherUnhandledExceptionEventArgs e)
    {
        if (!string.IsNullOrEmpty(e?.Exception?.StackTrace))
        {
            if (e.Exception.StackTrace.Contains("System.Windows.Controls.TextBlock.GetTextPositionFromDistance"))
            {
                e.Handled = true;

Include jquery.js and if it is included, load it before any other JavaScript code.

checked attribute is a boolean value so "checked" value of other "string" except boolean false converts to true.

Any string value will be true. Also presence of attribute make it true:

<input type="checkbox" checked>

You can make it uncheked only making boolean change in DOM using JS.

So the answer is: they are equal.

This worked for me.

sed -e 's/\s\+/,/g' input.txt >> output.csv

All these work:

#include <iostream>
using namespace std;

//Good, because manual memory management isn't needed and this uses
//less heap memory (or no heap memory) so this is safer if
//used in a low memory situation
void f() { throw string("foo"); }

//Valid, but avoid manual memory management if there's no reason to use it
void g() { throw new string("foo"); }

//Best.  Just a pointer to a string literal, so no allocation is needed,
//saving on cleanup, and removing a chance for an allocation to fail.
void h() { throw "foo"; }

int main() {
  try { f(); } catch (string s) { cout << s << endl; }
  try { g(); } catch (string* s) { cout << *s << endl; delete s; }
  try { h(); } catch (const char* s) { cout << s << endl; }
  return 0;
}

You should prefer h to f to g. Note that in the least preferable option you need to free the memory explicitly.

I was asking myself the same question few times. And even though the guys here tried hard to explain it, IMHO the best answer (and simplest) answer I have found is the description of the Class method in the Python Documentation.

There is also reference to the Static method. And in case someone already know instance methods (which I assume), this answer might be the final piece to put it all together...

Further and deeper elaboration on this topic can be found also in the documentation: The standard type hierarchy (scroll down to Instance methods section)

You can use wget which is popular downloading shell tool for that. https://pypi.python.org/pypi/wget This will be the simplest method since it does not need to open up the destination file. Here is an example.

import wget
url = 'https://i1.wp.com/python3.codes/wp-content/uploads/2015/06/Python3-powered.png?fit=650%2C350'  
wget.download(url, '/Users/scott/Downloads/cat4.jpg') 

The import allows the java programmer to access classes of a package without package qualification.

The static import feature allows to access the static members of a class without the class qualification.

The import provides accessibility to classes and interface whereas static import provides accessibility to static members of the class.

Example :

With import

import java.lang.System.*;    
class StaticImportExample{  
    public static void main(String args[]){  

       System.out.println("Hello");
       System.out.println("Java");  

  }   
} 

With static import

import static java.lang.System.*;    
class StaticImportExample{  
  public static void main(String args[]){  

   out.println("Hello");//Now no need of System.out  
   out.println("Java");  

 }   
}

It seems you don't even have to specify the compression any more. The following snippet loads the data from filename.zip into df.

df = pd.read_csv('filename.zip')

(Of course you will need to specify separator, header, etc. if they are different from the defaults.)

This is a program I wrote, which gets the number of days between 2 dates(no time here).

  System.out.print("Enter ending date separated by dots: ");
  String inp2 = s.nextLine();
  int[] nodim = {
   0,

   30,
   31,
   30,
   31
  };
  String[] inpArr1 = split(inp1);
  String[] inpArr2 = split(inp2);
  int d1 = Integer.parseInt(inpArr1[0]);
  int m1 = Integer.parseInt(inpArr1[1]);
  int y1 = Integer.parseInt(inpArr1[2]);
  int d2 = Integer.parseInt(inpArr2[0]);
  int m2 = Integer.parseInt(inpArr2[1]);
  int y2 = Integer.parseInt(inpArr2[2]);
  if (y1 % 4 == 0) nodim[2] = 29;
  int diff = m1 == m2 && y1 == y2 ? d2 - (d1 - 1) : (nodim[m1] - (d1 - 1));
  int mm1 = m1 + 1, mm2 = m2 - 1, yy1 = y1, yy2 = y2;
  for (; yy1 <= yy2; yy1++, mm1 = 1) {
   mm2 = yy1 == yy2 ? (m2 - 1) : 12;
   if (yy1 % 4 == 0) nodim[2] = 29;
   else nodim[2] = 28;
   if (mm2 == 0) {
    mm2 = 12;
    yy2 = yy2 - 1;
   }
   for (; mm1 <= mm2 && yy1 <= yy2; mm1++) diff = diff + nodim[mm1];
  }
  System.out.print("No. of days from " + inp1 + " to " + inp2 + " is " + diff);

I save files in .XLSB format to cut size. The XLSB also allows for VBA and macros to stay with the file. I've seen 50 meg files down to less than 10 with the Binary formatting.

An alternative using a closure to separate out the code into something a bit neater using Swift 4:

class theViewController: UIViewController {

    /** Create the UILabel */
    var theLabel: UILabel = {
        let label = UILabel()
        label.lineBreakMode = .byWordWrapping
        label.textColor = UIColor.white
        label.textAlignment = .left
        label.numberOfLines = 3
        label.font = UIFont(name: "Helvetica-Bold", size: 22)
        return label
    }()

    override func viewDidLoad() {
        /** Add theLabel to the ViewControllers view */
        view.addSubview(theLabel)
    }

    override func viewDidLayoutSubviews() {
        /* Set the frame when the layout is changed */
        theLabel.frame = CGRect(x: 0,
                                y: 0,
                                width: view.frame.width - 30,
                                height: 24)
    }
}

As a note, attributes for theLabel can still be changed whenever using functions in the VC. You're just setting various defaults inside the closure and minimizing clutter in functions like viewDidLoad()

import java.math.BigInteger;
import java.util.*;
class A
{
    public static void main(String args[])

        String a=in.next();
        System.out.print("Enter The Second Number= ");
        String b=in.next();

        BigInteger obj=new BigInteger(a);
        BigInteger obj1=new BigInteger(b);
        System.out.println("Sum="+obj.add(obj1));
    }
}

WHILE @NUM <= (SELECT COUNT(*) FROM #FIELD_LIST)
BEGIN
SET @FIELDS = @FIELDS + ',' + (SELECT COLUMN_NAME FROM #FIELD_LIST WHERE SEQ = @NUM)
SET @NUM = @NUM + 1
END

SET @FIELDS = RIGHT(@FIELDS,LEN(@FIELDS)-1)

EXEC('SELECT ' + @FIELDS + ', COUNT(*) AS QTY FROM [Req].[dbo].[new340B] GROUP BY ' + @FIELDS + ' HAVING COUNT(*) > 1  ')

You've instantiated text2 as an Optional (e.g. var text2: String?). This is why you receive Optional("5") in your string. take away the ? and replace with:

var text2: String = ""

For one, I'd strongly suggest updating to the latest Android Studio (0.3.7 as of now); there are tons of bug fixes.

You're running into bug https://code.google.com/p/android/issues/detail?id=57692, which is that if you try to use the UI to rename modules or your project, it doesn't update the build files. Sorry, it's really broken right now. I'd suggest changing the directory names directly in the filesystem, and updating your settings.gradle file to reflect the changes. Your project on disk should look something like this (with many more files than what's shown here):

projectFolder
|--settings.gradle
|--applicationModuleFolder
|  |--build.gradle
|  |--src

it uses projectFolder's name as the project name and applicationModuleFolder as the name of the module that your Android App lives in (the upper and lower outlined boxes in your screenshot, respectively). I think the way your project is set up now, they both have the same name; you can rename both to the same new name if you like, or you can give them different names; it doesn't matter.

Once they're renamed, edit your settings.gradle file; it will look something like:

include ':applicationModuleFolder'

just change the name to your new name there as well. Once these changes are made, click the Sync Project with Gradle Files button in the toolbar (if you're running a very old version of Android Studio, it may not have that button, so you can close the project and reopen it in that case) and it should pick up the changes.

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

Tested and working!

I am using Laravel 5.5.14 and none of the above worked for me. So here are the steps I did to make it work.

1.Install font-awesome by using npm:

   npm install font-awesome --save

2.Move the fonts to your public directory by adding this line in your webpack.mixin.js

mix.copyDirectory('node_modules/font-awesome/fonts', 'public/fonts/font-awesome');

3.Open your app.scss to specify the path of the fonts in your node_modules and which relative path to use for compilation:

$fa-font-path: "../fonts/font-awesome" !default;
@import "~font-awesome/scss/font-awesome.scss";

Yes, there is am Empty operator

Rx.Observable.empty();

For typescript, you can use from:

Rx.Observable<Response>.from([])

Try this. I set the blue box to float right, gave left and right a fixed height, and added a white border on the right of the left div. Also added rounded corners to more match your example (These won't work in ie 8 or less). I also took out the position: relative. You don't need it. Block level elements are set to position relative by default.

See it here: http://jsfiddle.net/ZSgLJ/

#left {
  float: left;
  width: 44%;
  margin: 0;
  padding: 0;
  border-right: 1px solid white;
  height:400px;
}

#right {
  position: relative;
  float: right;
  width: 49%;
  margin: 0;
  padding: 0;
  height:400px;
}

#blue_box {
  background-color:blue;
  border-radius: 10px;
  -moz-border-radius:10px;
  -webkit-border-radius: 10px;
  width: 45%;
  min-width: 400px;
  max-width: 600px;
  padding: 2%;
  float: right;
}

C# 4.0 also supports optional parameters, which could be useful in some other situations. See this article.

To get a list of the words that appear more than once together with how often they occur, use a combination of GROUP BY and HAVING:

SELECT word, COUNT(*) AS cnt
FROM words
GROUP BY word
HAVING cnt > 1

To find the number of words in the above result set, use that as a subquery and count the rows in an outer query:

SELECT COUNT(*)
FROM
(
    SELECT NULL
    FROM words
    GROUP BY word
    HAVING COUNT(*) > 1
) T1

<html>
<head>
    <style type="text/css">
    .title {
        color: blue;
        text-decoration: bold;
        text-size: 1em;
    }

    .author {
        color: gray;
    }
    </style>
</head>
<body>
    <p>
    <span class="title">La super bonne</span>
    <span class="author">proposée par Jérém</span>
    </p>
</body>
</html>

On a side note, it would have been much easier to just do this.

I know the question doesn't state SQL Server express, but its worth pointing out that the SQL Server Express editions don't come with the profiler (very annoying), and I suspect that they also don't come with the query analyzer.

I did try using a Monitor (code below) which appears to work but has a GOTCHA... when you have multiple threads it will give... System.Threading.SynchronizationLockException Object synchronization method was called from an unsynchronized block of code.

using System;
using System.Threading;
using System.Threading.Tasks;

namespace MyNamespace
{
    public class ThreadsafeFooModifier : 
    {
        private readonly object _lockObject;

        public async Task<FooResponse> ModifyFooAsync()
        {
            FooResponse result;
            Monitor.Enter(_lockObject);
            try
            {
                result = await SomeFunctionToModifyFooAsync();
            }
            finally
            {
                Monitor.Exit(_lockObject);
            }
            return result;
        }
    }
}

Prior to this I was simply doing this, but it was in an ASP.NET controller so it resulted in a deadlock.

public async Task<FooResponse> ModifyFooAsync() { lock(lockObject) { return SomeFunctionToModifyFooAsync.Result; } }

You can try this

var lastPostDate = reader[3] == DBNull.Value ?
                                default(DateTime?): 
                                Convert.ToDateTime(reader[3]);

From cppreference, one of the std::unique_ptr constructors is

explicit unique_ptr( pointer p ) noexcept;

So to create a new std::unique_ptr is to pass a pointer to its constructor.

unique_ptr<int> uptr (new int(3));

Or it is the same as

int *int_ptr = new int(3);
std::unique_ptr<int> uptr (int_ptr);

The different is you don't have to clean up after using it. If you don't use std::unique_ptr (smart pointer), you will have to delete it like this

delete int_ptr;

when you no longer need it or it will cause a memory leak.

[A-Za-z ]* to match letters and spaces.

You can use the "Join" function to create a single string out of the array of labels, like this:

=Join(Parameters!Product.Label, ",")

You can use array_sum().

$total = array_sum($group);

Use

text-align: right

The text-align CSS property describes how inline content like text is aligned in its parent block element. text-align does not control the alignment of block elements itself, only their inline content.

See

text-align

<td class='alnright'>text to be aligned to right</td>

<style>
    .alnright { text-align: right; }
</style>
