How is this possible? Without an index on the er101_upd_date_iso column how can a clustered index scan be used?

An index is a B-Tree where each leaf node is pointing to a 'bunch of rows'(called a 'Page' in SQL internal terminology), That is when the index is a non-clustered index.

Clustered index is a special case, in which the leaf nodes has the 'bunch of rows' (rather than pointing to them). that is why...

1) There can be only one clustered index on the table.

this also means the whole table is stored as the clustered index, that is why you started seeing index scan rather than a table scan.

2) An operation that utilizes clustered index is generally faster than a non-clustered index

For the problem you have, you should really consider adding this column to a index, as you said adding a new index (or a column to an existing index) increases INSERT/UPDATE costs. But it might be possible to remove some underutilized index (or a column from an existing index) to replace with 'er101_upd_date_iso'.

If index changes are not possible, i recommend adding a statistics on the column, it can fasten things up when the columns have some correlation with indexed columns

http://msdn.microsoft.com/en-us/library/ms188038.aspx

BTW, You will get much more help if you can post the table schema of ER101_ACCT_ORDER_DTL. and the existing indices too..., probably the query could be re-written to use some of them.

jQlite (angular's "jQuery" port) doesn't support lookup by classes.

One solution would be to include jQuery in your app.

Another is using QuerySelector or QuerySelectorAll:

link: function(scope, element, attrs) {
   console.log(element[0].querySelector('.list-scrollable'))
}

We use the first item in the element array, which is the HTML element. element.eq(0) would yield the same.

FIDDLE

According to the documentation.

If you are running on the TensorFlow or CNTK backends, your code will automatically run on GPU if any available GPU is detected.

You can check what all devices are used by tensorflow by -

from tensorflow.python.client import device_lib
print(device_lib.list_local_devices())

Also as suggested in this answer

import tensorflow as tf
sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))

This will print whether your tensorflow is using a CPU or a GPU backend. If you are running this command in jupyter notebook, check out the console from where you have launched the notebook.

If you are sceptic whether you have installed the tensorflow gpu version or not. You can install the gpu version via pip.

pip install tensorflow-gpu

I know this is a very old question. Just posting this here as I solved this problem using FlexBox. Here is the solution

#container {
  height: 100%;
  width: 100%;
  display: flex;
}
#leftThing {
  width: 25%;
  background-color: blue;
}
#content {
  width: 50%;
  background-color: green;
}
#rightThing {
  width: 25%;
  background-color: yellow;
}

<div id="container">

  <div id="leftThing">
    Left Side Menu
  </div>

  <div id="content">
    Random Content
  </div>

  <div id="rightThing">
    Right Side Menu
  </div>

</div>

Just had to add display:flex to the container! No floats required.

I had the same issue (on windows server 2003), check in the IIS console if you have allowed ASP.NET v4 service extension (under IIS / ComputerName / Web Service extensions)

The problem with your code is that when you do

 list[] == "e"

you're asking if the array object (not the contents) is equal to the string "e", which is clearly not the case.

You'll want to iterate over the contents in order to do the check you want:

 for(String element : list) {
      if (element.equals("e")) {
           // do something here
      }
 }

6 years late to the party but I've been searching for how to extract an html element's tag attribute value, so for:

<span property="addressLocality">Ayr</span>

I want "addressLocality". I kept being directed back here, but the answers didn't really solve my problem.

How I managed to do it eventually:

>>> from bs4 import BeautifulSoup as bs

>>> soup = bs('<span property="addressLocality">Ayr</span>', 'html.parser')
>>> my_attributes = soup.find().attrs
>>> my_attributes
{u'property': u'addressLocality'}

As it's a dict, you can then also use keys and 'values'

>>> my_attributes.keys()
[u'property']
>>> my_attributes.values()
[u'addressLocality']

Hopefully it helps someone else!

Using zip function we can get both element and index.

countries = ['Pakistan','India','China','Russia','USA']

for index, element zip(range(0,countries),countries):

         print('Index : ',index)
         print(' Element : ', element,'\n')

output : Index : 0 Element : Pakistan ...

Sometimes PostgreSQL fails to make the best choice of indexes for a particular condition. As an example, suppose there is a transactions table with several million rows, of which there are several hundred for any given day, and the table has four indexes: transaction_id, client_id, date, and description. You want to run the following query:

SELECT client_id, SUM(amount)
FROM transactions
WHERE date >= 'yesterday'::timestamp AND date < 'today'::timestamp AND
      description = 'Refund'
GROUP BY client_id

PostgreSQL may choose to use the index transactions_description_idx instead of transactions_date_idx, which may lead to the query taking several minutes instead of less than one second. If this is the case, you can force using the index on date by fudging the condition like this:

SELECT client_id, SUM(amount)
FROM transactions
WHERE date >= 'yesterday'::timestamp AND date < 'today'::timestamp AND
      description||'' = 'Refund'
GROUP BY client_id

Doesn't this work:

.clear-background{
background-image: none;
}

Might have problems on older browsers...

I think the annotation you are looking for is:

public class CompanyName implements Serializable {
//...
@JoinColumn(name = "COMPANY_ID", referencedColumnName = "COMPANY_ID", insertable = false, updatable = false)
private Company company;

And you should be able to use similar mappings in a hbm.xml as shown here (in 23.4.2):

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/example-mappings.html

You can also specify the range with the coord_cartesian command to set the y-axis range that you want, an like in the previous post use scales = free_x

p <- ggplot(plot, aes(x = pred, y = value)) +
     geom_point(size = 2.5) +
     theme_bw()+
     coord_cartesian(ylim = c(-20, 80))
p <- p + facet_wrap(~variable, scales = "free_x")
p

In your case you need to

1. Fix the ImageView's size. You need to use dp unit so that it will look the same in all devices.
2. Set android:scaleType to fitXY

Below is an example:

<ImageView
    android:id="@+id/photo"
    android:layout_width="200dp"
    android:layout_height="100dp"
    android:src="@drawable/iclauncher" 
    android:scaleType="fitXY"/>

For more information regarding ImageView scaleType please refer to the developer website.

Also be sure to set your JAVA_HOME environment variable. In fact, I usually set the JAVA_HOME, then prepend the string "%JAVA_HOME%\bin" to the system's PATH environment variable so that if Java ever gets upgraded or changed, only the JAVA_HOME variable will need to be changed.

And make sure that you close any command prompt windows or open applications that may read your environment variables, as changes to environment variables are normally not noticed until an application is re-launched.

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

Try this:

dbConfig.php

<?php
$mysqli = new mysqli('localhost', 'root', 'pwd', 'yr db name');
    if($mysqli->connect_error)
        {
        echo $mysqli->connect_error;
        }
    ?>

            $name = $_POST['txtname'];
            $pwd = $_POST['txtpwd'];
            $mysqli->query("insert into users(name,pwd) values('$name', '$pwd')");
        if(!$mysqli) 
        { echo mysqli_error(); }
    else
    {
        echo "Successfully Inserted <br />";
        echo "<a href='show.php'>View Result</a>";
    }

         }  

    ?>

Check with your host to see if they have any hourly limits to emails being sent.

Your example as written works perfectly in Chrome 11 for me. Perhaps your browser just doesn't support the :not() selector?

You may need to use JavaScript or similar to accomplish this cross-browser. jQuery implements :not() in its selector API.

EDIT: as of Java8 you'd better use Files class:

Path resultingPath = Files.createDirectories('A/B');

I don't know if this ultimately fixes your problem but class File has method mkdirs() which fully creates the path specified by the file.

File f = new File("/A/B/");
f.mkdirs();

Well there are thousand ways to edit a Text file on windows 7. Usually people Install Sublime , Atom and Notepad++ as an editor. For command line , I think the Basic Edit command (by the way which does not work on 64 bit computers) is good;Alternatively I find type con > filename as a very Applaudable method.If windows is newly installed and One wants to avoid Notepad. This might be it!! The perfect usage of Type as an editor :)

Your choices

• order from base
• arrange from dplyr
• setorder and setorderv from data.table
• arrange from plyr
• sort from taRifx
• orderBy from doBy
• sortData from Deducer

Most of the time you should use the dplyr or data.table solutions, unless having no-dependencies is important, in which case use base::order.

I recently added sort.data.frame to a CRAN package, making it class compatible as discussed here: Best way to create generic/method consistency for sort.data.frame?

Therefore, given the data.frame dd, you can sort as follows:

dd <- data.frame(b = factor(c("Hi", "Med", "Hi", "Low"), 
      levels = c("Low", "Med", "Hi"), ordered = TRUE),
      x = c("A", "D", "A", "C"), y = c(8, 3, 9, 9),
      z = c(1, 1, 1, 2))
library(taRifx)
sort(dd, f= ~ -z + b )

If you are one of the original authors of this function, please contact me. Discussion as to public domaininess is here: https://chat.stackoverflow.com/transcript/message/1094290#1094290

You can also use the arrange() function from plyr as Hadley pointed out in the above thread:

library(plyr)
arrange(dd,desc(z),b)

Benchmarks: Note that I loaded each package in a new R session since there were a lot of conflicts. In particular loading the doBy package causes sort to return "The following object(s) are masked from 'x (position 17)': b, x, y, z", and loading the Deducer package overwrites sort.data.frame from Kevin Wright or the taRifx package.

#Load each time
dd <- data.frame(b = factor(c("Hi", "Med", "Hi", "Low"), 
      levels = c("Low", "Med", "Hi"), ordered = TRUE),
      x = c("A", "D", "A", "C"), y = c(8, 3, 9, 9),
      z = c(1, 1, 1, 2))
library(microbenchmark)

# Reload R between benchmarks
microbenchmark(dd[with(dd, order(-z, b)), ] ,
    dd[order(-dd$z, dd$b),],
    times=1000
)

Median times:

dd[with(dd, order(-z, b)), ] 778

dd[order(-dd$z, dd$b),] 788

library(taRifx)
microbenchmark(sort(dd, f= ~-z+b ),times=1000)

Median time: 1,567

library(plyr)
microbenchmark(arrange(dd,desc(z),b),times=1000)

Median time: 862

library(doBy)
microbenchmark(orderBy(~-z+b, data=dd),times=1000)

Median time: 1,694

Note that doBy takes a good bit of time to load the package.

library(Deducer)
microbenchmark(sortData(dd,c("z","b"),increasing= c(FALSE,TRUE)),times=1000)

Couldn't make Deducer load. Needs JGR console.

esort <- function(x, sortvar, ...) {
attach(x)
x <- x[with(x,order(sortvar,...)),]
return(x)
detach(x)
}

microbenchmark(esort(dd, -z, b),times=1000)

Doesn't appear to be compatible with microbenchmark due to the attach/detach.

m <- microbenchmark(
  arrange(dd,desc(z),b),
  sort(dd, f= ~-z+b ),
  dd[with(dd, order(-z, b)), ] ,
  dd[order(-dd$z, dd$b),],
  times=1000
  )

uq <- function(x) { fivenum(x)[4]}  
lq <- function(x) { fivenum(x)[2]}

y_min <- 0 # min(by(m$time,m$expr,lq))
y_max <- max(by(m$time,m$expr,uq)) * 1.05
  
p <- ggplot(m,aes(x=expr,y=time)) + coord_cartesian(ylim = c( y_min , y_max )) 
p + stat_summary(fun.y=median,fun.ymin = lq, fun.ymax = uq, aes(fill=expr))

(lines extend from lower quartile to upper quartile, dot is the median)

Given these results and weighing simplicity vs. speed, I'd have to give the nod to arrange in the plyr package. It has a simple syntax and yet is almost as speedy as the base R commands with their convoluted machinations. Typically brilliant Hadley Wickham work. My only gripe with it is that it breaks the standard R nomenclature where sorting objects get called by sort(object), but I understand why Hadley did it that way due to issues discussed in the question linked above.

There is a class, Class, that can do this:

Class c = Class.forName("MyClass"); // if you want to specify a class
Class c = this.getClass();          // if you want to use the current class

System.out.println("Package: "+c.getPackage()+"\nClass: "+c.getSimpleName()+"\nFull Identifier: "+c.getName());

If c represented the class MyClass in the package mypackage, the above code would print:

Package: mypackage
Class: MyClass
Full Identifier: mypackage.MyClass

You can take this information and modify it for whatever you need, or go check the API for more information.

Simple as:

DateTime.Now.ToString("MM.dd.yyyy");

        textBox1.Enabled = false;

"false" property will make the text box disable. and "true" will make it in regular form. Thanks.

AutoScroll is really the solution! You just have to set AutoScrollMargin to 0, 1000 or something like this, then use it to scroll down and add buttons and items there!

zxing does not (only) provide a web API; really, that is Google providing the API, from source code that was later open-sourced in the project.

As Rob says here you can use the Java source code for the QR code encoder to create a raw barcode and then render it as a Bitmap.

I can offer an easier way still. You can call Barcode Scanner by Intent to encode a barcode. You need just a few lines of code, and two classes from the project, under android-integration. The main one is IntentIntegrator. Just call shareText().

As @John Henckel suggests, starting using the toISOString() method makes things easier

const dateString = new Date().toISOString().split('-');_x000D_
const year = dateString[0];_x000D_
const month = dateString[1];_x000D_
const day = dateString[2].split('T')[0];_x000D_
_x000D_
console.log(`${year}-${month}-${day}`);

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

First, let me go over a few terms. If you just want your question answered, scroll down to "Answering your question".

Definitions

Object identity: When you create an object, you can assign it to a variable. You can then also assign it to another variable. And another.

>>> button = Button()
>>> cancel = button
>>> close = button
>>> dismiss = button
>>> print(cancel is close)
True

In this case, cancel, close, and dismiss all refer to the same object in memory. You only created one Button object, and all three variables refer to this one object. We say that cancel, close, and dismiss all refer to identical objects; that is, they refer to one single object.

Object equality: When you compare two objects, you usually don't care that it refers to the exact same object in memory. With object equality, you can define your own rules for how two objects compare. When you write if a == b:, you are essentially saying if a.__eq__(b):. This lets you define a __eq__ method on a so that you can use your own comparison logic.

Rationale for equality comparisons

Rationale: Two objects have the exact same data, but are not identical. (They are not the same object in memory.) Example: Strings

>>> greeting = "It's a beautiful day in the neighbourhood."
>>> a = unicode(greeting)
>>> b = unicode(greeting)
>>> a is b
False
>>> a == b
True

Note: I use unicode strings here because Python is smart enough to reuse regular strings without creating new ones in memory.

Here, I have two unicode strings, a and b. They have the exact same content, but they are not the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the unicode object has implemented the __eq__ method.

class unicode(object):
    # ...

    def __eq__(self, other):
        if len(self) != len(other):
            return False

        for i, j in zip(self, other):
            if i != j:
                return False

        return True

Note: __eq__ on unicode is definitely implemented more efficiently than this.

Rationale: Two objects have different data, but are considered the same object if some key data is the same. Example: Most types of model data

>>> import datetime
>>> a = Monitor()
>>> a.make = "Dell"
>>> a.model = "E770s"
>>> a.owner = "Bob Jones"
>>> a.warranty_expiration = datetime.date(2030, 12, 31)
>>> b = Monitor()
>>> b.make = "Dell"
>>> b.model = "E770s"
>>> b.owner = "Sam Johnson"
>>> b.warranty_expiration = datetime.date(2005, 8, 22)
>>> a is b
False
>>> a == b
True

Here, I have two Dell monitors, a and b. They have the same make and model. However, they neither have the same data nor are the same object in memory. However, when we compare them, we want them to compare equal. What's happening here is that the Monitor object implemented the __eq__ method.

class Monitor(object):
    # ...

    def __eq__(self, other):
        return self.make == other.make and self.model == other.model

Answering your question

When comparing to None, always use is not. None is a singleton in Python - there is only ever one instance of it in memory.

By comparing identity, this can be performed very quickly. Python checks whether the object you're referring to has the same memory address as the global None object - a very, very fast comparison of two numbers.

By comparing equality, Python has to look up whether your object has an __eq__ method. If it does not, it examines each superclass looking for an __eq__ method. If it finds one, Python calls it. This is especially bad if the __eq__ method is slow and doesn't immediately return when it notices that the other object is None.

Did you not implement __eq__? Then Python will probably find the __eq__ method on object and use that instead - which just checks for object identity anyway.

When comparing most other things in Python, you will be using !=.

You have to allocate the array first:

int [] terms = new int[400]; // allocate an array of 400 ints
for(int runs = 0; runs < terms.Length; runs++) // Use Length property rather than the 400 magic number again
{
    terms[runs] = value;
}

arrayData.forEach((key : any, val: any) => {
                        key['index'] = val + 1;

                        arrayData2.forEach((keys : any, vals :any) => {
                            if (key.group_id == keys.id) {
                                key.group_name = keys.group_name;
                            }
                        })
                    })

ALTER TABLE t_name modify c_name INT(10) AUTO_INCREMENT PRIMARY KEY;

As Darren commented, Apache don't understand php.ini relative paths in Windows.

To fix it, change the relative paths in your php.ini to absolute paths.

extension_dir="C:\full\path\to\php\ext\dir"

Here's a simple one written in VB for an ASPX page:

                If myVar > 1 Then
                    response.write("Greater than 1")
                else
                    response.write("Not!")
                End If

The following will work with new versions of jQuery.

$(window).on('load', function(){

    var toggle = false;

    $('button').click(function() {
        toggle = !toggle;

        if(toggle){
            $('#B').animate({left: 0});
        }
        else{
            $('#B').animate({left: 200});
        }

    });
});

You could use cursor.lastrowid (see "Optional DB API Extensions"):

connection=sqlite3.connect(':memory:')
cursor=connection.cursor()
cursor.execute('''CREATE TABLE foo (id integer primary key autoincrement ,
                                    username varchar(50),
                                    password varchar(50))''')
cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('test','test'))
print(cursor.lastrowid)
# 1

If two people are inserting at the same time, as long as they are using different cursors, cursor.lastrowid will return the id for the last row that cursor inserted:

cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('blah','blah'))

cursor2=connection.cursor()
cursor2.execute('INSERT INTO foo (username,password) VALUES (?,?)',
               ('blah','blah'))

print(cursor2.lastrowid)        
# 3
print(cursor.lastrowid)
# 2

cursor.execute('INSERT INTO foo (id,username,password) VALUES (?,?,?)',
               (100,'blah','blah'))
print(cursor.lastrowid)
# 100

Note that lastrowid returns None when you insert more than one row at a time with executemany:

cursor.executemany('INSERT INTO foo (username,password) VALUES (?,?)',
               (('baz','bar'),('bing','bop')))
print(cursor.lastrowid)
# None

You can't actually do the job quite right with toLowerCase, either on a string or in a character. The problem is that there are variant glyphs in either upper or lower case, and depending on whether you uppercase or lowercase your glyphs may or may not be preserved. It's not even clear what you mean when you say that two variants of a lower-case glyph are compared ignoring case: are they or are they not the same? (Note that there are also mixed-case glyphs: \u01c5, \u01c8, \u01cb, \u01f2 or ?, ?, ?, ?, but any method suggested here will work on those as long as they should count as the same as their fully upper or full lower case variants.)

There is an additional problem with using Char: there are some 80 code points not representable with a single Char that are upper/lower case variants (40 of each), at least as detected by Java's code point upper/lower casing. You therefore need to get the code points and change the case on these.

But code points don't help with the variant glyphs.

Anyway, here's a complete list of the glyphs that are problematic due to variants, showing how they fare against 6 variant methods:

1. Character toLowerCase
2. Character toUpperCase
3. String toLowerCase
4. String toUpperCase
5. String equalsIgnoreCase
6. Character toLowerCase(toUpperCase) (or vice versa)

For these methods, S means that the variants are treated the same as each other, D means the variants are treated as different from each other.

Complicating this still further is that there is no way to get the Turkish I's right (i.e. the dotted versions are different than the undotted versions) unless you know you're in Turkish; none of these methods give correct behavior and cannot unless you know the locale (i.e. non-Turkish: i and I are the same ignoring case; Turkish, not).

Overall, using toUpperCase gives you the closest approximation, since you have only five uppercase variants (or four, not counting Turkish).

You can also try to specifically intercept those five troublesome cases and call toUpperCase(toLowerCase(c)) on them alone. If you choose your guards carefully (just toUpperCase if c < 0x130 || c > 0x212B, then work through the other alternatives) you can get only a ~20% speed penalty for characters in the low range (as compared to ~4x if you convert single characters to strings and equalsIgnoreCase them) and only about a 2x penalty if you have a lot in the danger zone. You still have the locale problem with dotted I, but otherwise you're in decent shape. Of course if you can use equalsIgnoreCase on a larger string, you're better off doing that.

Here is sample Scala code that does the job:

def elevateCase(c: Char): Char = {
  if (c < 0x130 || c > 0x212B) Character.toUpperCase(c)
  else if (c == 0x130 || c == 0x3F4 || c == 0x2126 || c >= 0x212A)
    Character.toUpperCase(Character.toLowerCase(c))
  else Character.toUpperCase(c)
}

Apple OSX Folder Actions allow you to automate tasks based on actions taken on a folder.

Like that:

$ command >>output 2>>error

Your code works fine, except that the barplot is ordered from low to high. When you want to order the bars from high to low, you will have to add a -sign before value:

ggplot(corr.m, aes(x = reorder(miRNA, -value), y = value, fill = variable)) + 
  geom_bar(stat = "identity")

which gives:

Used data:

corr.m <- structure(list(miRNA = structure(c(5L, 2L, 3L, 6L, 1L, 4L), .Label = c("mmu-miR-139-5p", "mmu-miR-1983", "mmu-miR-301a-3p", "mmu-miR-5097", "mmu-miR-532-3p", "mmu-miR-96-5p"), class = "factor"),
                         variable = structure(c(1L, 1L, 1L, 1L, 1L, 1L), .Label = "pos", class = "factor"),
                         value = c(7L, 75L, 70L, 5L, 10L, 47L)),
                    class = "data.frame", row.names = c("1", "2", "3", "4", "5", "6"))

boolean is a primitive data type in Java and primitive data types can not be null like other primitives int, float etc, they should be containing default values if not assigned.

In Java, only objects can assigned to null, it means the corresponding object has no reference and so does not contain any representation in memory.

Hence If you want to work with object as null , you should be using Boolean class which wraps a primitive boolean type value inside its object.

These are called wrapper classes in Java

For Example:

Boolean bool = readValue(...); // Read Your Value
if (bool  == null) { do This ...}

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

I'm giving you the fiddle_demo

This is because width when provided a % doesn't account for padding/margins. You will need to reduce the amount to possibly 24% or 24.5%. Once this is done you should be good, but you will need to provide different options based on the screen size if you want this to always work correct since you have a hardcoded margin, but a relative size.

Small hint which other people didn't talk about: git doesn't record changes if you add empty folders in your project folder. That's it, I was adding empty folders with random names to check wether it was recording changes, it wasn't. But it started to do it as soon as I began adding files in them. Cheers.

Here is a practical addition to the answers of PierreBdR and Moe:

• For Python >= 2.6 and new-style classes, dir() seems to be enough.

• For old-style classes, we can at least do what a standard module does to support tab completion: in addition to dir(), look for __class__, and then to go for its __bases__:

  # code borrowed from the rlcompleter module
  # tested under Python 2.6 ( sys.version = '2.6.5 (r265:79063, Apr 16 2010, 13:09:56) \n[GCC 4.4.3]' )
  
  # or: from rlcompleter import get_class_members
  def get_class_members(klass):
      ret = dir(klass)
      if hasattr(klass,'__bases__'):
          for base in klass.__bases__:
              ret = ret + get_class_members(base)
      return ret
  
  
  def uniq( seq ): 
      """ the 'set()' way ( use dict when there's no set ) """
      return list(set(seq))
  
  
  def get_object_attrs( obj ):
      # code borrowed from the rlcompleter module ( see the code for Completer::attr_matches() )
      ret = dir( obj )
      ## if "__builtins__" in ret:
      ##    ret.remove("__builtins__")
  
      if hasattr( obj, '__class__'):
          ret.append('__class__')
          ret.extend( get_class_members(obj.__class__) )
  
          ret = uniq( ret )
  
      return ret
  

(Test code and output are deleted for brevity, but basically for new-style objects we seem to have the same results for get_object_attrs() as for dir(), and for old-style classes the main addition to the dir() output seem to be the __class__ attribute.)

Jérôme Petazzoni has a pretty interesting blog post on how to Attach a volume to a container while it is running. This isn't something that's built into Docker out of the box, but possible to accomplish.

As he also points out

This will not work on filesystems which are not based on block devices.

It will only work if /proc/mounts correctly lists the block device node (which, as we saw above, is not necessarily true).

Also, I only tested this on my local environment; I didn’t even try on a cloud instance or anything like that

YMMV

Ask them how they ensure their pages continue to be usable when the user has JavaScript turned off or JavaScript isn't available.

There's no One True Answer, but you're fishing for an answer talking about some strategies for Progressive Enhancement.

Progressive Enhancement consists of the following core principles:

• basic content should be accessible to all browsers
• basic functionality should be accessible to all browsers
• sparse, semantic markup contains all content
• enhanced layout is provided by externally linked CSS
• enhanced behavior is provided by [[Unobtrusive JavaScript|unobtrusive]], externally linked JavaScript
• end user browser preferences are respected

sudo apt-get update
sudo apt-get install openjdk-7-jdk

and if you already have other JDK versions installed

sudo update-alternatives --config java

then select the Java 7 version.

Here's a simple method to do it: The (ip >> 8), (ip >> 16) and (ip >> 24) moves the 2nd, 3rd and 4th bytes into the lower order byte, while the & 0xFF isolates the least significant byte at each step.

void print_ip(unsigned int ip)
{
    unsigned char bytes[4];
    bytes[0] = ip & 0xFF;
    bytes[1] = (ip >> 8) & 0xFF;
    bytes[2] = (ip >> 16) & 0xFF;
    bytes[3] = (ip >> 24) & 0xFF;   
    printf("%d.%d.%d.%d\n", bytes[3], bytes[2], bytes[1], bytes[0]);        
}

There is an implied bytes[0] = (ip >> 0) & 0xFF; at the first step.

Use snprintf() to print it to a string.

If Tuple has no key repetitions, it's Simple.

tup = [("A",0),("B",3),("C",5)]
dic = dict(tup)
print(dic)

If tuple has key repetitions.

tup = [("A",0),("B",3),("C",5),("A",9),("B",4)]
dic = {}
for i, j in tup:
    dic.setdefault(i,[]).append(j)
print(dic)

I know this is old, but I had trouble with some solutions and pieced this together. I have tested this on Windows (Chrome, Firefox and MSIE) and OS X (Chrome and Safari) and believe this is the simplest solution. It works with these three style of attaching a label.

<label><input type="checkbox" class="c123" id="cb1" name="item1">item1</label>

<input type="checkbox" class="c123" id="cb2" name="item2">item2</input>

<input type="checkbox" class="c123" id="cb3" name="item3"><label for="cb3">item3</label>

Using jQuery:

$(".c123").click(function() {
    $cb = $(this);
    $lb = $(this).parent();
    alert( $cb.attr('id') + ' = ' + $lb.text() );
});

My JSFiddle: http://jsfiddle.net/pnosko/6PQCw/

This is how simply I sort from previous examples:

if my array is items:

0: {id: 14, auctionID: 76, userID: 1, amount: 39}
1: {id: 1086, auctionID: 76, userID: 1, amount: 55}
2: {id: 1087, auctionID: 76, userID: 1, amount: 55}

I thought simply calling items.sort() would sort it it, but there was two problems: 1. Was sorting them strings 2. Was sorting them first key

This is how I modified the sort function:

for(amount in items){
if(item.hasOwnProperty(amount)){

i.sort((a, b) => a.amount - b.amount);
}
}

In Objective-C all methods start with either a "-" or "+" character. Example:

@interface MyClass : NSObject
// instance method
- (void) instanceMethod;

+ (void) classMethod;
@end

The "+" and "-" characters specify whether a method is a class method or an instance method respectively.

The difference would be clear if we call these methods. Here the methods are declared in MyClass.

instance method require an instance of the class:

MyClass* myClass = [[MyClass alloc] init];
[myClass instanceMethod];

Inside MyClass other methods can call instance methods of MyClass using self:

-(void) someMethod
{
    [self instanceMethod];
}

But, class methods must be called on the class itself:

[MyClass classMethod];

Or:

MyClass* myClass = [[MyClass alloc] init];
[myClass class] classMethod];

This won't work:

// Error
[myClass classMethod];
// Error
[self classMethod];

If you are in Android Studio Open Terminal

Otherwise

Open Command prompt and got android

You need to do two things. First add the changes with

git add .
git stash  

git checkout <some branch>

It should solve your issue as it solved to me.

Use:

CSS

#subparent {
    overflow: hidden;
    width: 500px;
    border: 1px rgba(0, 0, 0, 1.00) solid;
}

#parent {
    width: 515px;
    height: 300px;
    overflow-y: auto;
    overflow-x: hidden;
    opacity: 10%;
}

#child {
    width: 511px;
    background-color: rgba(123, 8, 10, 0.42);
}

HTML

<body>
    <div id="subparent">
        <div id="parent">
            <div id="child">
                <!- Code here for scroll ->
            </div>
        </div>
     </div>
</body>

You can enable connection logging. For SQL Server 2008, you can enable Login Auditing. In SQL Server Management Studio, open SQL Server Properties > Security > Login Auditing select "Both failed and successful logins".

Make sure to restart the SQL Server service.

Once you've done that, connection attempts should be logged into SQL's error log. The physical logs location can be determined here.

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

Here are the differences that can help you understand the advantages of persist and save methods:

• First difference between save and persist is their return type. The return type of persist method is void while return type of save
  method is Serializable object.

• The persist() method doesn’t guarantee that the identifier value will be assigned to the persistent state immediately, the assignment might happen at flush time.

• The persist() method will not execute an insert query if it is called outside of transaction boundaries. While, the save() method returns an identifier so that an insert query is executed immediately to get the identifier, no matter if it are inside or outside of a transaction.

• The persist method is called outside of transaction boundaries, it is useful in long-running conversations with an extended Session context. On the other hand save method is not good in a long-running conversation with an extended Session context.

• Fifth difference between save and persist method in Hibernate: persist is supported by JPA, while save is only supported by Hibernate.

You can see the full working example from the post Difference between save and persist method in Hibernate

Thanks for all answers above, but for me, I can not find Base64Encoder class, so I sort out my way anyway.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        String encoding = DatatypeConverter.printBase64Binary("user:passwd".getBytes("UTF-8"));
        httpGet.setHeader("Authorization", "Basic " + encoding);

        HttpResponse response = Client.execute(httpGet);

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

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String repsonseStr = responseString.toString();

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

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

}

One more thing, I also tried

Base64.encodeBase64String("user:passwd".getBytes());

It does NOT work due to it return a string almost same with

DatatypeConverter.printBase64Binary()

but end with "\r\n", then server will return "bad request".

Also following code is working as well, actually I sort out this first, but for some reason, it does NOT work in some cloud environment (sae.sina.com.cn if you want to know, it is a chinese cloud service). so have to use the http header instead of HttpClient credentials.

public static void main(String[] args) {
    try {
        DefaultHttpClient Client = new DefaultHttpClient();
        Client.getCredentialsProvider().setCredentials(
                AuthScope.ANY,
                new UsernamePasswordCredentials("user", "passwd")
        );

        HttpGet httpGet = new HttpGet("https://httpbin.org/basic-auth/user/passwd");
        HttpResponse response = Client.execute(httpGet);

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

        BufferedReader breader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
        StringBuilder responseString = new StringBuilder();
        String line = "";
        while ((line = breader.readLine()) != null) {
            responseString.append(line);
        }
        breader.close();
        String responseStr = responseString.toString();
        System.out.println("responseStr = " + responseStr);

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

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");

});

You can create a .pth file that contains the directory to search for, and place it in the {venv-root}/lib/{python-version}/site-packages directory. E.g.:

cd $(python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib())")
echo /some/library/path > some-library.pth

The effect is the same as adding /some/library/path to sys.path, and remain local to the virtualenv setup.

time_point objects only support arithmetic with other time_point or duration objects.

You'll need to convert your long to a duration of specified units, then your code should work correctly.

I know this is kind of late for a response. But I did run into this error and I found a solution here: https://rvm.io/integration/gnome-terminal

You just have to enable 'Run command as login shell' under the terminal preferences.

In Vue2 be aware that you can access this.$refs.uniqueName only after mounting the component.

Everything in python is considered as object so functions are also objects. So you can use this method as well.

def fun1():
    fun1.var = 100
    print(fun1.var)

def fun2():
    print(fun1.var)

fun1()
fun2()

print(fun1.var)

I figured out myself.

cmp calls ComputeBetasAndNuHat which returns a list which has objective as minusloglik

So I can change the function cmp to get this value.

dataGridView1.DataSource=null;

I prefer not to alter the path hierarchy, but instead deal with git specifically...knowing that I'm never going to use old git to do what new git will now manage. This is a brute force solution.

$('#table1').find(input).length

One workaround that I only just discovered is to actually just run PyLint for the entire package, rather than a single file. Somehow, it manages to find imported module then.

It's only blank for you because you have not set the sql_mode. If you set it, then that query will show you the details:

git log --reflog

saved me! I lost mine while merging HEAD and could not find my lates commit! Not showing in source tree but git log --reflog show all my local commits before

I came upon this post looking to do the same and came up with my own solution I wanted to offer for future visitors of this page (and to see if doing this way presents any problems I had not forseen).

If you want to get a simple true or false output and want to do this with one line of code without a function or a loop you could serialize the array and then use stripos to search for the value:

stripos(serialize($my_array),$needle)

It seems to work for me.

This applies to all languages:

You want to have an event/listener model. You create a listener to wait for a particular event. The event would be created (or signaled) in your worker thread. This will block the thread until the signal is received instead of constantly polling to see if a condition is met, like the solution you currently have.

Your situation is one of the most common causes for deadlocks- make sure you signal the other thread regardless of errors that may have occurred. Example- if your application throws an exception- and never calls the method to signal the other that things have completed. This will make it so the other thread never 'wakes up'.

I suggest that you look into the concepts of using events and event handlers to better understand this paradigm before implementing your case.

Alternatively you can use a blocking function call using a mutex- which will cause the thread to wait for the resource to be free. To do this you need good thread synchronization- such as:

Thread-A Locks lock-a
Run thread-B
Thread-B waits for lock-a
Thread-A unlocks lock-a (causing Thread-B to continue)
Thread-A waits for lock-b 
Thread-B completes and unlocks lock-b

This is solution for browsers with webkit render engine. When the form is autofilled, the inputs will get pseudo class :-webkit-autofill- (f.e. input:-webkit-autofill {...}). So this is the identifier what you must check via JavaScript.

Solution with some test form:

<form action="#" method="POST" class="js-filled_check">

    <fieldset>

        <label for="test_username">Test username:</label>
        <input type="text" id="test_username" name="test_username" value="">

        <label for="test_password">Test password:</label>
        <input type="password" id="test_password" name="test_password" value="">

        <button type="submit" name="test_submit">Test submit</button>

    </fieldset>

</form>

And javascript:

$(document).ready(function() {

    setTimeout(function() {

        $(".js-filled_check input:not([type=submit])").each(function (i, element) {

            var el = $(this),
                autofilled = (el.is("*:-webkit-autofill")) ? el.addClass('auto_filled') : false;

            console.log("element: " + el.attr("id") + " // " + "autofilled: " + (el.is("*:-webkit-autofill")));

        });

    }, 200);

});

Problem when the page loads is get password value, even length. This is because browser's security. Also the timeout, it's because browser will fill form after some time sequence.

This code will add class auto_filled to filled inputs. Also, I tried to check input type password value, or length, but it's worked just after some event on the page happened. So I tried trigger some event, but without success. For now this is my solution. Enjoy!

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

This error is pretty self-explanatory. There seem to be data missing in the first line of your data file (or second line, as the case may be since you're using header = TRUE).

Here's a mini example:

## Create a small dataset to play with
cat("V1 V2\nFirst 1 2\nSecond 2\nThird 3 8\n", file="test.txt")

R automatically detects that it should expect rownames plus two columns (3 elements), but it doesn't find 3 elements on line 2, so you get an error:

read.table("test.txt", header = TRUE)
# Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  : 
#   line 2 did not have 3 elements

Look at the data file and see if there is indeed a problem:

cat(readLines("test.txt"), sep = "\n")
# V1 V2
# First 1 2
# Second 2
# Third 3 8

Manual correction might be needed, or we can assume that the value first value in the "Second" row line should be in the first column, and other values should be NA. If this is the case, fill = TRUE is enough to solve your problem.

read.table("test.txt", header = TRUE, fill = TRUE)
#        V1 V2
# First   1  2
# Second  2 NA
# Third   3  8

R is also smart enough to figure it out how many elements it needs even if rownames are missing:

cat("V1 V2\n1\n2 5\n3 8\n", file="test2.txt")
cat(readLines("test2.txt"), sep = "\n")
# V1 V2
# 1
# 2 5
# 3 8
read.table("test2.txt", header = TRUE)
# Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings,  : 
#   line 1 did not have 2 elements
read.table("test2.txt", header = TRUE, fill = TRUE)
#   V1 V2
# 1  1 NA
# 2  2  5
# 3  3  8

Add this in MainActivity.

Intent intent = new Intent(getApplicationContext(), Heightimage.class);
startActivity(intent);

Use datetime.datetime.fromtimestamp:

>>> import datetime
>>> s = 1236472051807 / 1000.0
>>> datetime.datetime.fromtimestamp(s).strftime('%Y-%m-%d %H:%M:%S.%f')
'2009-03-08 09:27:31.807000'

%f directive is only supported by datetime.datetime.strftime, not by time.strftime.

UPDATE Alternative using %, str.format:

>>> import time
>>> s, ms = divmod(1236472051807, 1000)  # (1236472051, 807)
>>> '%s.%03d' % (time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'
>>> '{}.{:03d}'.format(time.strftime('%Y-%m-%d %H:%M:%S', time.gmtime(s)), ms)
'2009-03-08 00:27:31.807'

To get the timedelta(), you should subtract 1900-01-01:

>>> from datetime import datetime
>>> datetime.strptime('01:01:09,000', '%H:%M:%S,%f')
datetime.datetime(1900, 1, 1, 1, 1, 9)
>>> td = datetime.strptime('01:01:09,000', '%H:%M:%S,%f') - datetime(1900,1,1)
>>> td
datetime.timedelta(0, 3669)
>>> td.total_seconds() # 2.7+
3669.0

%H above implies the input is less than a day, to support the time difference more than a day:

>>> import re
>>> from datetime import timedelta
>>> td = timedelta(**dict(zip("hours minutes seconds milliseconds".split(),
...                           map(int, re.findall('\d+', '31:01:09,000')))))
>>> td
datetime.timedelta(1, 25269)
>>> td.total_seconds()
111669.0

To emulate .total_seconds() on Python 2.6:

>>> from __future__ import division
>>> ((td.days * 86400 + td.seconds) * 10**6 + td.microseconds) / 10**6
111669.0

display:none removes the element from the layout flow.

visibility:hidden hides it but leaves the space.

The order of execution of ng-click and ng-model is ambiguous since they do not define clear priorities. Instead you should use ng-change or a $watch on the $scope to ensure that you obtain the correct values of the model variable.

In your case, this should work:

<input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">

If you're treating it as a tuple (see section 3.3.3 of the language spec), then:

var t:[number, string] = [1, "message"]

or

interface NumberStringTuple extends Array<string|number>{0:number; 1:string}
var t:NumberStringTuple = [1, "message"];

You can use:

WHERE LEFT (name_field, 1) = 'B';

Just try to create the marker and set the draggable property to true. The code will be something as follows:

Marker = new google.maps.Marker({
    position: latlon,
    map: map,            
    draggable: true,
    title: "Drag me!"
});

I hope this helps!

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

First check if you are in the right database USE yourDB and try Select * from contenttype just to see what is it and if it exists really...

Another thing that messed things up for me was using localhost instead of 127.0.0.1 or vice versa. Apparently, JavaScript can't handle requests from one to the other.

I know this question is old, but the solution to my application, was different to the already suggested answers. If anyone else like me still have this issue, and none of the above answers works, this might be the problem:

I used a Network Credentials object to parse a windows username+password to a third party SOAP webservice. I had set the username="domainname\username", password="password" and domain="domainname". Now this game me that strange Ntlm and not NTLM error. To solve the problems, make sure not to use the domain parameter on the NetworkCredentials object if the domain name is included in the username with the backslash. So either remove domain name from the username and parse in domain parameter, or leave out the domain parameter. This solved my issue.

Things seem to have changed since Angular 2.0.0

import { Observable } from 'rxjs/Observable';
import { Subscriber } from 'rxjs/Subscriber';
// ...
public fetchModel(uuid: string = undefined): Observable<string> {
  if(!uuid) {
    return new Observable<TestModel>((subscriber: Subscriber<TestModel>) => subscriber.next(new TestModel())).map(o => JSON.stringify(o));
  }
  else {
    return this.http.get("http://localhost:8080/myapp/api/model/" + uuid)
            .map(res => res.text());
  }
}

The .next() function will be called on your subscriber.

I'm using these function to get year, month, day from the date

you should put them in a class

    public function getYear($pdate) {
        $date = DateTime::createFromFormat("Y-m-d", $pdate);
        return $date->format("Y");
    }

    public function getMonth($pdate) {
        $date = DateTime::createFromFormat("Y-m-d", $pdate);
        return $date->format("m");
    }

    public function getDay($pdate) {
        $date = DateTime::createFromFormat("Y-m-d", $pdate);
        return $date->format("d");
    }

The Distinct() is going to mess up the ordering, so you'll have to the sorting after that.

var uniqueColors = 
               (from dbo in database.MainTable 
                 where dbo.Property == true 
                 select dbo.Color.Name).Distinct().OrderBy(name=>name);

Much easier way of doing it: you will need com.google.gson.Gson for converting the object to json string for streaming

to convert object to json string for streaming use below code

Gson gson = new Gson();
String jsonString = gson.toJson(MyObject);

To convert back the json string to object use below code:

Gson gson = new Gson();
MyObject = gson.fromJson(decodedString , MyObjectClass.class);

Much easier way to convert object for streaming and read on the other side. Hope this helps. - Vishesh

The ternary operator ? : is to return a value, don't use it when you want to use if for flow control.

if (compareChar(curChar, toChar("0"))) getButtons().get(i).setText("§");

would work good enough.

I'm not so thrilled about the InetAddress.getLocalHost().getHostName() solution that you can find so many places on the Internet and indeed also here. That method will get you the hostname as seen from a network perspective. I can see two problems with this:

1. What if the host has multiple network interfaces ? The host may be known on the network by multiple names. The one returned by said method is indeterminate afaik.

2. What if the host is not connected to any network and has no network interfaces ?

All OS'es that I know of have the concept of naming a node/host irrespective of network. Sad that Java cannot return this in an easy way. This would be the environment variable COMPUTERNAME on all versions of Windows and the environment variable HOSTNAME on Unix/Linux/MacOS (or alternatively the output from host command hostname if the HOSTNAME environment variable is not available as is the case in old shells like Bourne and Korn).

I would write a method that would retrieve (depending on OS) those OS vars and only as a last resort use the InetAddress.getLocalHost().getHostName() method. But that's just me.

UPDATE (Unices)

As others have pointed out the HOSTNAME environment variable is typically not available to a Java application on Unix/Linux as it is not exported by default. Hence not a reliable method unless you are in control of the clients. This really sucks. Why isn't there a standard property with this information?

Alas, as far as I can see the only reliable way on Unix/Linux would be to make a JNI call to gethostname() or to use Runtime.exec() to capture the output from the hostname command. I don't particularly like any of these ideas but if anyone has a better idea I'm all ears. (update: I recently came across gethostname4j which seems to be the answer to my prayers).

Long read

I've created a long explanation in another answer on another post. In particular you may want to read it because it attempts to establish some terminology, gives concrete examples of when the InetAddress.getLocalHost().getHostName() solution will fail, and points to the only safe solution that I know of currently, namely gethostname4j.

It's sad that Java doesn't provide a method for obtaining the computername. Vote for JDK-8169296 if you are able to.

I solved this by getting the Bluetooth name, but not from the BluetoothAdapter (that needs Bluetooth permission).

Here's the code:

Settings.Secure.getString(getContentResolver(), "bluetooth_name");

No extra permissions needed.

Actually, the jQuery documentation has a more simple approach than the chained examples shown above (although they'll work just fine):

$("#myElement").unbind('mouseenter mouseleave');

As of jQuery 1.7, you are also able use $.on() and $.off() for event binding, so to unbind the hover event, you would use the simpler and tidier:

$('#myElement').off('hover');

The pseudo-event-name "hover" is used as a shorthand for "mouseenter mouseleave" but was handled differently in earlier jQuery versions; requiring you to expressly remove each of the literal event names. Using $.off() now allows you to drop both mouse events using the same shorthand.

Edit 2016:

Still a popular question so it's worth drawing attention to @Dennis98's point in the comments below that in jQuery 1.9+, the "hover" event was deprecated in favour of the standard "mouseenter mouseleave" calls. So your event binding declaration should now look like this:

$('#myElement').off('mouseenter mouseleave');

Using LIKE will give you options for defining what the rest of the string should look like, but if the rule is just starts with 'NoHist_' it doesn't really matter.

Test with a setTimeout, that worked for me and I could submit my form, refers to this answer https://stackoverflow.com/a/779785/5510314

$(document).ready(function () {
    $("#btnSubmit").click(function () {
        setTimeout(function () { disableButton(); }, 0);
    });

    function disableButton() {
        $("#btnSubmit").prop('disabled', true);
    }
});

According To Apple you don't need an import for swift files in the Same Target. I finally got it working by adding my swift file to both my regular target and test target. Then I used the bridging header for test to make sure my ObjC files that I referenced in my regular bridging header were available. Ran like a charm now.

import XCTest
//Optionally you can import the whole Objc Module by doing #import ModuleName

class HHASettings_Tests: XCTestCase {

override func setUp() {
    let x : SettingsTableViewController = SettingsTableViewController()

    super.setUp()
    // Put setup code here. This method is called before the invocation of each test method in the class.
}

override func tearDown() {
    // Put teardown code here. This method is called after the invocation of each test method in the class.
    super.tearDown()
}

func testExample() {
    // This is an example of a functional test case.
    XCTAssert(true, "Pass")
}

func testPerformanceExample() {
    // This is an example of a performance test case.
    self.measureBlock() {
        // Put the code you want to measure the time of here.
    }
}

}

SO make sure PrimeNumberModel has a target of your test Target. Or High6 solution of importing your whole module will work

This will call git blame for every meaningful revision to show line $LINE of file $FILE:

git log --format=format:%H $FILE | xargs -L 1 git blame $FILE -L $LINE,$LINE

As usual, the blame shows the revision number in the beginning of each line. You can append

| sort | uniq -c

to get aggregated results, something like a list of commits that changed this line. (Not quite, if code only has been moved around, this might show the same commit ID twice for different contents of the line. For a more detailed analysis you'd have to do a lagged comparison of the git blame results for adjacent commits. Anyone?)

In Java you would do something similar to:

Transport transport = session.getTransport("smtps");
transport.connect (smtp_host, smtp_port, smtp_username, smtp_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();    

Note 'smtpS' protocol. Also socketFactory properties is no longer necessary in modern JVMs but you might need to set 'mail.smtps.auth' and 'mail.smtps.starttls.enable' to 'true' for Gmail. 'mail.smtps.debug' could be helpful too.

the best solution for me:

function GetIEVersion() {_x000D_
  var sAgent = window.navigator.userAgent;_x000D_
  var Idx = sAgent.indexOf("MSIE");_x000D_
  // If IE, return version number._x000D_
  if (Idx > 0)_x000D_
    return parseInt(sAgent.substring(Idx+ 5, sAgent.indexOf(".", Idx)));_x000D_
_x000D_
  // If IE 11 then look for Updated user agent string._x000D_
  else if (!!navigator.userAgent.match(/Trident\/7\./))_x000D_
    return 11;_x000D_
_x000D_
  else_x000D_
    return 0; //It is not IE_x000D_
_x000D_
}_x000D_
if (GetIEVersion() > 0){_x000D_
    alert("This is IE " + GetIEVersion());_x000D_
  }else {_x000D_
    alert("This no is IE ");_x000D_
  }  

In my opinion that is easiest and fastest way:

$ npm -v

4.2.0

$ npm install -g npm@latest-3

...

$ npm -v

3.10.10

Try using an a link element and click it with javascriipt

<a id="SimulateOpenLink" href="#" target="_blank" rel="noopener noreferrer"></a>

and the script

function openURL(url) {
    document.getElementById("SimulateOpenLink").href = url
    document.getElementById("SimulateOpenLink").click()
}

Use it like this

//do stuff
var id = 123123141;
openURL("/api/user/" + id + "/print") //this open webpage bypassing pop-up blocker
openURL("https://www.google.com") //Another link

here is my solution

string var = "Hello345wor705Ld";
string alpha = string.Empty;
string numer = string.Empty;
foreach (char str in var)
{
    if (char.IsDigit(str))
        numer += str.ToString();
    else
        alpha += str.ToString();
}
Console.WriteLine("String is: " + alpha);
Console.WriteLine("Numeric character is: " + numer);
Console.Read();

Just remove "build" folder in youy project directory and compile again, i hope it works for you too

This should do the trick:

$('#some_select_box').click(function() {
  $('option:selected', this ).remove();
});

In addition to the anwser of Bill the Lizard:

Most of the backends parse the raw post data. In PHP for example, you will have an array $_POST in which individual variables within the post data will be stored. In this case you have to use an additional header "Content-type: application/x-www-form-urlencoded":

Set objHTTP = CreateObject("WinHttp.WinHttpRequest.5.1")
URL = "http://www.somedomain.com"
objHTTP.Open "POST", URL, False
objHTTP.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0)"
objHTTP.setRequestHeader "Content-type", "application/x-www-form-urlencoded"
objHTTP.send ("var1=value1&var2=value2&var3=value3")

Otherwise you have to read the raw post data on the variable "$HTTP_RAW_POST_DATA".

Ctrl+Shift+Space shows the Edit.ParameterInfo for the selected method, and by selected method I mean the caret must be within the method parentheses.

Here is the Visual Studio 2010 Keybinding Poster.

And for those still using 2008.

create div with id name

var divCreator=function (id){
newElement=document.createElement("div");
newNode=document.body.appendChild(newElement);
newNode.setAttribute("id",id);
}

add text to div

var textAdder = function(id, text) {
target = document.getElementById(id)
target.appendChild(document.createTextNode(text));
}

test code

divCreator("div1");

DateTime.Today is DateTime.Now with time set to zero.

It is important to note that there is a difference between a DateTime value, which represents the number of ticks that have elapsed since midnight of January 1, 0000, and the string representation of that DateTime value, which expresses a date and time value in a culture-specific-specific format: https://msdn.microsoft.com/en-us/library/system.datetime.now%28v=vs.110%29.aspx

DateTime.Now.Ticks is the actual time stored by .net (essentially UTC time), the rest are just representations (which are important for display purposes).

If the Kind property is DateTimeKind.Local it implicitly includes the time zone information of the local computer. When sending over a .net web service, DateTime values are by default serialized with time zone information included, e.g. 2008-10-31T15:07:38.6875000-05:00, and a computer in another time zone can still exactly know what time is being referred to.

So, using DateTime.Now and DateTime.Today is perfectly OK.

You usually start running into trouble when you begin confusing the string representation with the actual value and try to "fix" the DateTime, when it isn't broken.

Since 10gR2, Oracle allows to fine-tune the behaviour of string comparisons by setting the NLS_COMP and NLS_SORT session parameters:

SQL> SET HEADING OFF
SQL> SELECT *
  2  FROM NLS_SESSION_PARAMETERS
  3  WHERE PARAMETER IN ('NLS_COMP', 'NLS_SORT');

NLS_SORT
BINARY

NLS_COMP
BINARY


SQL>
SQL> SELECT CASE WHEN 'abc'='ABC' THEN 1 ELSE 0 END AS GOT_MATCH
  2  FROM DUAL;

         0

SQL>
SQL> ALTER SESSION SET NLS_COMP=LINGUISTIC;

Session altered.

SQL> ALTER SESSION SET NLS_SORT=BINARY_CI;

Session altered.

SQL>
SQL> SELECT *
  2  FROM NLS_SESSION_PARAMETERS
  3  WHERE PARAMETER IN ('NLS_COMP', 'NLS_SORT');

NLS_SORT
BINARY_CI

NLS_COMP
LINGUISTIC


SQL>
SQL> SELECT CASE WHEN 'abc'='ABC' THEN 1 ELSE 0 END AS GOT_MATCH
  2  FROM DUAL;

         1

You can also create case insensitive indexes:

create index
   nlsci1_gen_person
on
   MY_PERSON
   (NLSSORT
      (PERSON_LAST_NAME, 'NLS_SORT=BINARY_CI')
   )
;

This information was taken from Oracle case insensitive searches. The article mentions REGEXP_LIKE but it seems to work with good old = as well.

In versions older than 10gR2 it can't really be done and the usual approach, if you don't need accent-insensitive search, is to just UPPER() both the column and the search expression.

I've tried in a sample project to use standard, @2x and @3x images, and the iPhone 6+ simulator uses the @3x image. So it would seem that there are @3x images to be done (if the simulator actually replicates the device's behavior). But the strange thing is that all devices (simulators) seem to use this @3x image when it's on the project structure, iPhone 4S/iPhone 5 too.
The lack of communication from Apple on a potential @3x structure, while they ask developers to publish their iOS8 apps is quite confusing, especially when seeing those results on simulator.

**Edit from Apple's Website **: Also found this on the "What's new on iOS 8" section on Apple's developer space :

Support for a New Screen Scale The iPhone 6 Plus uses a new Retina HD display with a screen scale of 3.0. To provide the best possible experience on these devices, include new artwork designed for this screen scale. In Xcode 6, asset catalogs can include images at 1x, 2x, and 3x sizes; simply add the new image assets and iOS will choose the correct assets when running on an iPhone 6 Plus. The image loading behavior in iOS also recognizes an @3x suffix.

Still not understanding why all devices seem to load the @3x. Maybe it's because I'm using regular files and not xcassets ? Will try soon.

Edit after further testing : Ok it seems that iOS8 has a talk in this. When testing on an iOS 7.1 iPhone 5 simulator, it uses correctly the @2x image. But when launching the same on iOS 8 it uses the @3x on iPhone 5. Not sure if that's a wanted behavior or a mistake/bug in iOS8 GM or simulators in Xcode 6 though.

I took Nico Burns's answer and made it using jQuery:

• Generic: For every div contentEditable="true"
• Shorter

You'll need jQuery 1.6 or higher:

savedRanges = new Object();
$('div[contenteditable="true"]').focus(function(){
    var s = window.getSelection();
    var t = $('div[contenteditable="true"]').index(this);
    if (typeof(savedRanges[t]) === "undefined"){
        savedRanges[t]= new Range();
    } else if(s.rangeCount > 0) {
        s.removeAllRanges();
        s.addRange(savedRanges[t]);
    }
}).bind("mouseup keyup",function(){
    var t = $('div[contenteditable="true"]').index(this);
    savedRanges[t] = window.getSelection().getRangeAt(0);
}).on("mousedown click",function(e){
    if(!$(this).is(":focus")){
        e.stopPropagation();
        e.preventDefault();
        $(this).focus();
    }
});

add this to you CSS:

html, body
{
    height: 100%;
}

working Fiddle

when you say to wrap to be 100%, 100% of what? of its parent (body), so his parent has to have some height.

and the same goes for body, his parent his html. html parent his the viewport.. so, by setting them both to 100%, wrap can also have a percentage height.

also: the elements have some default padding/margin, that causes them to span a little more then the height you applied to them. (causing a scroll bar) you can use

*
{
    padding: 0;
    margin: 0;
}

to disable that.

Look at That Fiddle

The first answer is correct, but if you have a large amount of data (in my project I had 8.000 rows * 8 columns) is tragically slow.... Having a string that becomes that large in c# is why that solution is forbiden

Instead using a large string I used a string array that I join at the end in order to return the string of the html table. Moreover, I used a linq expression ((from o in row.ItemArray select o.ToString()).ToArray()) in order to join each DataRow of the table, instead of looping again, in order to save as much time as possible.

This is my sample code:

private string MakeHtmlTable(DataTable data)
{
            string[] table = new string[data.Rows.Count] ;
            long counter = 1;
            foreach (DataRow row in data.Rows)
            {
                table[counter-1] = "<tr><td>" + String.Join("</td><td>", (from o in row.ItemArray select o.ToString()).ToArray()) + "</td></tr>";

                counter+=1;
            }

            return "</br><table>" + String.Join("", table) + "</table>";
}

In oracle, generally speaking, there are number of facts that I will mention in following section:

• Each database can have many Schema/User (Logical division).
• Each database can have many tablespaces (Logical division).
• A schema is the set of objects (tables, indexes, views, etc) that belong to a user.
• In Oracle, a user can be considered the same as a schema.
• A database is divided into logical storage units called tablespaces, which group related logical structures together. For example, tablespaces commonly group all of an application’s objects to simplify some administrative operations. You may have a tablespace for application data and an additional one for application indexes.

Therefore, your question, "to see all tablespaces and datafiles belong to SCOTT" is s bit wrong.

However, there are some DBA views encompass information about all database objects, regardless of the owner. Only users with DBA privileges can access these views: DBA_DATA_FILES, DBA_TABLESPACES, DBA_FREE_SPACE, DBA_SEGMENTS.

So, connect to your DB as sysdba and run query through these helpful views. For example this query can help you to find all tablespaces and their data files that objects of your user are located:

SELECT DISTINCT sgm.TABLESPACE_NAME , dtf.FILE_NAME
FROM DBA_SEGMENTS sgm
JOIN DBA_DATA_FILES dtf ON (sgm.TABLESPACE_NAME = dtf.TABLESPACE_NAME)
WHERE sgm.OWNER = 'SCOTT'

One correct answer is:

/a/b/*[self::c or self::d or self::e]

Do note that this

a/b/*[local-name()='c' or local-name()='d' or local-name()='e']

is both too-long and incorrect. This XPath expression will select nodes like:

OhMy:c

NotWanted:d 

QuiteDifferent:e

>>> import re
>>> filename = "Example_file_(extra_descriptor).ext"
>>> p = re.compile(r'\([^)]*\)')
>>> re.sub(p, '', filename)
'Example_file_.ext'

Check the root folder of your Magento installation directory .You will find maintenance.flag file, delete it and refresh the site .it will work fine.

Rand does not get you a random number. It gives you the next number in a sequence generated by a pseudorandom number generator. To get a different sequence every time you start your program, you have to seed the algorithm by calling srand.

A (very bad) way to do it is by passing it the current time:

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main() {
    srand(time(NULL));
    int i, j = 0;
    for(i = 0; i <= 10; i++) {
        j = rand();
        printf("j = %d\n", j);
    }
    return 0;
}

Why this is a bad way? Because a pseudorandom number generator is as good as its seed, and the seed must be unpredictable. That is why you may need a better source of entropy, like reading from /dev/urandom.

Simply,

    $res = (object)array("success"=>false); // $res->success = bool(false);

Or you could instantiate classes with:

    $res = (object)array(); // object(stdClass) -> recommended

    $res = (object)[];      // object(stdClass) -> works too

    $res = new \stdClass(); // object(stdClass) -> old method

and fill values with:

    $res->success = !!0;     // bool(false)

    $res->success = false;   // bool(false)

    $res->success = (bool)0; // bool(false)

If you're creating a framework the whole idea is to make it portable. Tying a framework to the app delegate defeats the purpose of building a framework. What is it you need the app delegate for?

I quote from http://www.php.net/manual/en/language.oop5.visibility.php

Note: The PHP 4 method of declaring a variable with the var keyword is still supported for compatibility reasons (as a synonym for the public keyword). In PHP 5 before 5.1.3, its usage would generate an E_STRICT warning.

Best way is to use the Carbon dependency.

With Carbon\Carbon::now(); you get the current Datetime.

With Carbon you can do like enything with the DateTime. Event things like this:

$tomorrow = Carbon::now()->addDay();
$lastWeek = Carbon::now()->subWeek();

        List<int> a = new List<int>() { 1, 2, 3, 4, 5 };
        a.ForEach(p => Console.WriteLine(p));

edit: ahhh he beat me to it.

For me, this occurred after updating to XCode 11, like the others have said, it is a signing issue. What fixed it for me was to go to Developer portal > Certificates & Identifiers Edit the provisioning profile you are using

List of certificates Screenshot

You'll see that there's certificate for XCode 11 (as seen on screenshot) Just tick that box, re download the profile, and update your projects signing with the new profile.

lubos hasko's method fails for nullables. The method below will work for nullables. I didn't come up with it, though. I found it via Google: http://web.archive.org/web/20101214042641/http://dogaoztuzun.com/post/C-Generic-Type-Conversion.aspx Credit to "Tuna Toksoz"

Usage first:

TConverter.ChangeType<T>(StringValue);  

The class is below.

public static class TConverter
{
    public static T ChangeType<T>(object value)
    {
        return (T)ChangeType(typeof(T), value);
    }

    public static object ChangeType(Type t, object value)
    {
        TypeConverter tc = TypeDescriptor.GetConverter(t);
        return tc.ConvertFrom(value);
    }

    public static void RegisterTypeConverter<T, TC>() where TC : TypeConverter
    {

        TypeDescriptor.AddAttributes(typeof(T), new TypeConverterAttribute(typeof(TC)));
    }
}

There's a nodejs tool which supports json schema v4 at https://github.com/krg7880/json-schema-generator

It works either as a command line tool, or as a nodejs library:

var jsonSchemaGenerator = require('json-schema-generator'),
    obj = { some: { object: true } },
    schemaObj;

schemaObj = jsonSchemaGenerator(json);

Interestingly putting <httpCookies httpOnlyCookies="false"/> doesn't seem to disable httpOnlyCookies in ASP.NET 2.0. Check this article about SessionID and Login Problems With ASP .NET 2.0.

Looks like Microsoft took the decision to not allow you to disable it from the web.config. Check this post on forums.asp.net

Try this:

$pagename = get_query_var('pagename');

you could use the font style Like:

     <font color="white"><h1>Header Content</h1></font>

assuming that no other closing square bracket is allowed within, /FOO\[([^\]]*)\]/

You can create a custom directive that is somehow similar to ng-disabled and disable a specific set of elements by:

1. watching the property changes of the custom directive, e.g. my-disabled.
2. clone the current element without the added event handlers.
3. add css properties to the cloned element and other attributes or event handlers that will provide the disabled state of an element.
4. when changes are detected on the watched property, replace the current element with the cloned element.

HTML

   <a my-disabled="disableCreate" href="#" ng-click="disableEdit = true">CREATE</a><br/>
   <a my-disabled="disableEdit" href="#" ng-click="disableCreate = true">EDIT</a><br/>
   <a my-disabled="disableCreate || disableEdit" href="#">DELETE</a><br/>
   <a href="#" ng-click="disableEdit = false; disableCreate = false;">RESET</a>

JAVASCRIPT

directive('myDisabled', function() {
  return {

    link: function(scope, elem, attr) {
      var color = elem.css('color'),
          textDecoration = elem.css('text-decoration'),
          cursor = elem.css('cursor'),
          // double negation for non-boolean attributes e.g. undefined
          currentValue = !!scope.$eval(attr.myDisabled),

          current = elem[0],
          next = elem[0].cloneNode(true);

      var nextElem = angular.element(next);

      nextElem.on('click', function(e) {
        e.preventDefault();
        e.stopPropagation();
      });

      nextElem.css('color', 'gray');
      nextElem.css('text-decoration', 'line-through');
      nextElem.css('cursor', 'not-allowed');
      nextElem.attr('tabindex', -1);

      scope.$watch(attr.myDisabled, function(value) {
        // double negation for non-boolean attributes e.g. undefined
        value = !!value;

        if(currentValue != value) {
          currentValue = value;
          current.parentNode.replaceChild(next, current);
          var temp = current;
          current = next;
          next = temp;
        }

      })
    }
  }
});

The first thing I want to make clear is that branch names are just an alias to a specific commit. a commit is what git works off, when you pull, push merge and so forth. Each commit has a unique id.

When you do $ git merge , what is actually happening is git tries to fast forward your current branch to to the commit the referenced branch is on (in other words both branch names point to the same commit.) This scenario is the easiest for git to deal, since there's no new commit. Think of master jumping onto the lilipad your branch is chilling on. It's possible to set the --no-ff flag, in which case git will create a new commit regardless of whether there were any code conflicts.

In a situation where there are code conflicts between the two branches you are trying to merge (usually two branches whose commit history share a common commit in the past), the fast forward won't work. git may still be able to automatically merge the files, so long as the same line wasn't changed by both branches in a conflicting file. in this case, git will merge the conflicting files for you AND automatically commit them. You can preview how git did by doing $ git diff --cached. Or you can pass the --no-commit flag to the merge command, which will leave modified files in your index you'll need to add and commit. But you can $ git diff these files to review what the merge will change.

The third scenario is when there are conflicts git can't automatically resolve. In this case you'll need to manually merge them. In my opinion this is easiest to do with a merge took, like araxis merge or p4merge (free). Either way, you have to do each file one by one. If the merge ever seems to be stuck, use $ git merge --continue, to nudge it along. Git should tell you if it can't continue, and if so why not. If you feel you loused up the merge at some point, you can do $ git merge --abort, and any merging will undo and you can start over. When you're done, each file you merged will be a modified file that needs to be added and committed. You can verify where the files are with $ git status. If you haven't committed the merged files yet. You need to do that to complete the merge. You have to complete the merge or abort the merge before you can switch branches.

As Wingman said, Google App Engine is a great solution for your scenario.

You can get some information about GAE+Android here: https://developers.google.com/eclipse/docs/appengine_connected_android

And from this Google IO 2012 session: http://www.youtube.com/watch?v=NU_wNR_UUn4

Vulgo has the right idea on this thread. I believe his solution is the easiest of the bunch, although his answer could have been a little more in-depth. Here is something that worked for me. I have provided an example.

<h1 id="hello1">Hello World</h1>
<h2 id="hello2">Random</h2>
<button id="click">Click To Hide</button>

<script>

  document.getElementById('click').addEventListener('click', function(){
    doStuff();
  });

  function doStuff() {
    for(var i=1; i<=2; i++){
        var el = document.getElementById("hello" + i);
        el.style.display = 'none';
    }
  }

</script>

Obviously just change the integers in the for loop to account for however many elements you are targeting, which in this example was 2.

simple just use the img tag helper. Rails knows to look in the images folder in the asset pipeline, you can use it like this

<%= image_tag "image.jpg" %>

var key = "Name_radio";
var val = "value_radio";
var rdo = $('*[name="' + key + '"]');
if (rdo.attr('type') == "radio") {
 $.each(rdo, function (keyT, valT){
   if ((valT.value == $.trim(val)) && ($.trim(val) != '') && ($.trim(val) != null))

   {
     $('*[name="' + key + '"][value="' + (val) + '"]').prop('checked', true);
   }
  })
}

ctype_digit was built precisely for this purpose.

i had the same problem before

the error code 3417 : the SQL SERVER cannot start the master database, without master db SQL SERVER can't start MSSQLSERVER_3417

The master database records all the system-level information for a SQL Server system. This includes instance-wide metadata such as logon accounts, endpoints, linked servers, and system configuration settings. In SQL Server, system objects are no longer stored in the master database; instead, they are stored in the Resource database. Also, master is the database that records the existence of all other databases and the location of those database files and records the initialization information for SQL Server. Therefore, SQL Server cannot start if the master database is unavailable MSDN Master DB so you need to reconfigure all settings after restoring master db

solutions

• replace master mdf and ldf files with the same files from another instance of sql Server as long as its the same version reference
• Rebuild System Databases refrence
• reinstall sql server

here is my methods, it is a little bit convince that number of bytes fixed

private void printByte(int value) {
String currentBinary = Integer.toBinaryString(256 + value);
System.out.println(currentBinary.substring(currentBinary.length() - 8));
}

public int binaryToInteger(String binary) {
char[] numbers = binary.toCharArray();
int result = 0;
for(int i=numbers.length - 1; i>=0; i--)
  if(numbers[i]=='1')
    result += Math.pow(2, (numbers.length-i - 1));
return result;
}

You are probably using the wrong certificate file, what you need to do is generate a self signed certificate which can be done as follows

openssl req -newkey rsa:2048 -new -nodes -keyout key.pem -out csr.pem
openssl x509 -req -days 365 -in csr.pem -signkey key.pem -out server.crt

then use the server.crt

   var options = {
      key: fs.readFileSync('./key.pem', 'utf8'),
      cert: fs.readFileSync('./server.crt', 'utf8')
   };

Although already over a year old, I stumbled across this question a couple of times on other Google search and I believe I can improve on the previous answer for the benefit of others.

Short answer is you cannot combine both action in one line, but you can create a chain that does what you want and then call it in a one liner.

Let's create a chain to log and accept:

iptables -N LOG_ACCEPT

And let's populate its rules:

iptables -A LOG_ACCEPT -j LOG --log-prefix "INPUT:ACCEPT:" --log-level 6
iptables -A LOG_ACCEPT -j ACCEPT

Now let's create a chain to log and drop:

iptables -N LOG_DROP

And let's populate its rules:

iptables -A LOG_DROP -j LOG --log-prefix "INPUT:DROP: " --log-level 6
iptables -A LOG_DROP -j DROP

Now you can do all actions in one go by jumping (-j) to you custom chains instead of the default LOG / ACCEPT / REJECT / DROP:

iptables -A <your_chain_here> <your_conditions_here> -j LOG_ACCEPT
iptables -A <your_chain_here> <your_conditions_here> -j LOG_DROP

Try putting the search condition in a bracket, as shown below. This returns the result of the conditional query inside the bracket. Then test its result to determine if it is negative (i.e. it does not belong to any of the options in the vector), by setting it to FALSE.

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
(where_case_travelled_1 %in% c('Outside Canada','Outside province/territory of residence but within Canada')) == FALSE)

In your xampppath\apache\conf\extra open file httpd-xampp.conf and find the below tag:

# Close XAMPP sites here
<LocationMatch "^/(?i:(?:xampp|licenses|phpmyadmin|webalizer|server-status|server-info))">
    Order deny,allow
    Deny from all
    Allow from ::1 127.0.0.0/8 
    ErrorDocument 403 /error/HTTP_XAMPP_FORBIDDEN.html.var
</LocationMatch>

and add

"Allow from all"

after Allow from ::1 127.0.0.0/8 {line}

Restart xampp, and you are done.

In later versions of Xampp

...you can simply remove this part

#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
        Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</LocationMatch>

from the same file and it should work over the local network.

It's possible in ggplot and you can use scale_date for this task

 library(ggplot2)  
 Lines <- "Date            Visits
    11/1/2010   696537
    11/2/2010   718748
    11/3/2010   799355
    11/4/2010   805800
    11/5/2010   701262
    11/6/2010   531579
    11/7/2010   690068
    11/8/2010   756947
    11/9/2010   718757
    11/10/2010  701768
    11/11/2010  820113
    11/12/2010  645259"
    dm <- read.table(textConnection(Lines), header = TRUE)
    dm <- mutate(dm, Date = as.Date(dm$Date, "%m/%d/%Y"))
    ggplot(data = dm, aes(Date, Visits)) + 
    geom_line() + 
    scale_x_date(format = "%b %d", major =  "1 day")

The following worked for me:

ax2.xaxis.set_tick_params(labelsize=7)
ax2.yaxis.set_tick_params(labelsize=7)

The advantage of the above is you do not need to provide the array of labels and works with any data on the axes.

I needed to know how to get the actual error code number.

I inherited a project from someone else and I had to get the error codes from a .catch clause that they had previously setup for Alamofire:

} .catch { (error) in

    guard let error = error as? AFError else { return }
    guard let statusCode = error.responseCode else { return }

    print("Alamofire statusCode num is: ", statusCode)
}

Or if you need to get it from the response value follow @mbryzinski's answer

Alamofire ... { (response) in

    guard let error = response.result.error as? AFError else { return }
    guard let statusCode = error.responseCode else { return }

    print("Alamofire statusCode num is: ", statusCode)
})

The default iterator for the JObject is as a dictionary iterating over key/value pairs.

JObject obj = JObject.Parse(response);
foreach (var pair in obj) {
    Console.WriteLine (pair.Key);
}

NO, you can't do it other way than so.

For a File

git add -u
git reset -- main/dontcheckmein.txt

For a folder

git add -u
git reset -- main/*

There is a data structure called deque or double ended queue which is faster and efficient than a list. You can use your list and convert it to deque and do the required transformations in it. You can also convert the deque back to list.

import collections
mylist = [0, 1, 2, 3, 4]

#make a deque from your list
de = collections.deque(mylist)

#you can remove from a deque from either left side or right side
de.popleft()
print(de)

#you can covert the deque back to list
mylist = list(de)
print(mylist)

Deque also provides very useful functions like inserting elements to either side of the list or to any specific index. You can also rotate or reverse a deque. Give it a try!

Was asked here before: Unix command to find lines common in two files

You could also try with perl (credit goes here)

perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/'  file1 file2

It's suprising that no one mentioned about run-one. I've solved my problem with this.

 apt-get install run-one

then add run-one before your crontab script

As discussed above, we need to implement Select Class in Selenium and further we can use various available methods like :-

There is a confusion that is causing a lot of TortoiseSVN users to use the wrong command line tools when they actually were looking for svn.exe command line client.

What should I do or can't TortoiseSVN be used from the command line?

svn.exe

If you want to run Subversion commands from the command prompt, you should run the svn.exe command line client. TortoiseSVN 1.6.x and older versions did not include SVN command-line tools, but modern versions do.

If you want to get SVN command line tools without having to install TortoiseSVN, check the SVN binary distributions page or simply download the latest version from VisualSVN downloads page.

If you have SVN command line tools installed on your system, but still get the error 'svn' is not recognized as an internal or external command, you should check %PATH% environment variable. %PATH% must include the path to SVN tools directory e.g. C:\Program Files (x86)\VisualSVN\bin.

TortoiseProc.exe

Apart from svn.exe, TortoiseSVN comes with TortoiseProc.exe that can be called from command prompt. In most cases, you do not need to use this tool, because it should be only used for GUI automation. TortoiseProc.exe is not a replacement for SVN command-line client.

Declare @variable type(size);

Set @variable = 'String' or Int ;

Example:

 Declare @id int;
 set @id = 10;

 Declare @str char(50);
 set @str='Hello' ; 

Simple example below. Note you should pass in a larger buffer, and test to see if the buffer was large enough or not

void Log(LPCWSTR pFormat, ...) 
{
    va_list pArg;
    va_start(pArg, pFormat);
    char buf[1000];
    int len = _vsntprintf(buf, 1000, pFormat, pArg);
    va_end(pArg);
    //do something with buf
}

The best way I found to resolve this issue was by using a combination of the above. All my cells were entered as a Custom Format to only show "HH:MM" - if I entered in "4:06" (being 4 minutes and 6 seconds) the field would show the numbers I entered correctly - but the data itself would represent HH:MM in the background.

Fortunately time is based on factors of 60 (60 seconds = 60 minutes). So 7H:15M / 60 = 7M:15S - I hope you can see where this is going. Accordingly, if I take my 4:06 and divide by 60 when working with the data (eg. to total up my total time or average time across 100 cells I would use the normal SUM or AVERAGE formulas and then divide by 60 in the formula.

Example =(SUM(A1:A5))/60. If my data was across the 5 time tracking fields was the 4:06, 3:15, 9:12, 2:54, 7:38 (representing MM:SS for us, but the data in the background is actually HH:MM) then when I work out the sum of those 5 fields are, what I want should be 27M:05S but what shows instead is 1D:03H:05M:00S. As mentioned above, 1D:3H:5M divided by 60 = 27M:5S ... which is the sum I am looking for.

Further examples of this are: =(SUM(G:G))/60 and =(AVERAGE(B2:B90)/60) and =MIN(C:C) (this is a direct check so no /60 needed here!).

Note that your "formula" or "calculation" fields (average, total time, etc) MUST have the custom format of MM:SS once you have divided by 60 as Excel's default thinking is in HH:MM (hence this issue). Your data fields where you are entering in your times should need to be changed from "General" or "Number" format to the custom format of HH:MM.

This process is still a little bit cumbersome to use - but it does mean that your data entry is still entered in very easy and is "correctly" displayed on screen as 4:06 (which most people would view as minutes:seconds when under a "Minutes" header). Generally there will only be a couple of fields needing to be used for formulas such as "best time", "average time", "total time" etc when tracking times and they will not usually be changed once the formula is entered so this will be a "one off" process - I use this for my call tracking sheet at work to track "average call", "total call time for day".

You may want to look at how you can use the built-in features of .NET to serialize and deserialize an object into XML, rather than creating a ToXML() method on every class that is essentially just a Data Transfer Object.

I have used these techniques successfully on a couple of projects but don’t have the implementation details handy right now. I will try to update my answer with my own examples sometime later.

Here's a couple of examples that Google returned:

XML Serialization in .NET by Venkat Subramaniam http://www.agiledeveloper.com/articles/XMLSerialization.pdf

How to Serialize and Deserialize an object into XML http://www.dotnetfunda.com/articles/article98.aspx

I got the same error. it was because I was accessing the https port using http.. The issue solved when I changed http to https.

More portable to use ed; some systems don't support \n in sed

printf "/^lorem ipsum dolor sit amet/a\nconsectetur adipiscing elit\n.\nw\nq\n" |\
    /bin/ed $filename

object cannot be defined staticly but this works

final Class B{
  static $var;
  static function init(){
    self::$var = new A();
}
B::init();

Here is how it works:

1. Get XML element string with FOR XML

Adding FOR XML PATH to the end of a query allows you to output the results of the query as XML elements, with the element name contained in the PATH argument. For example, if we were to run the following statement:

SELECT ',' + name 
              FROM temp1
              FOR XML PATH ('')

By passing in a blank string (FOR XML PATH('')), we get the following instead:

,aaa,bbb,ccc,ddd,eee

2. Remove leading comma with STUFF

The STUFF statement literally "stuffs” one string into another, replacing characters within the first string. We, however, are using it simply to remove the first character of the resultant list of values.

SELECT abc = STUFF((
            SELECT ',' + NAME
            FROM temp1
            FOR XML PATH('')
            ), 1, 1, '')
FROM temp1

The parameters of STUFF are:

• The string to be “stuffed” (in our case the full list of name with a leading comma)
• The location to start deleting and inserting characters (1, we’re stuffing into a blank string)
• The number of characters to delete (1, being the leading comma)

So we end up with:

aaa,bbb,ccc,ddd,eee

3. Join on id to get full list

Next we just join this on the list of id in the temp table, to get a list of IDs with name:

SELECT ID,  abc = STUFF(
             (SELECT ',' + name 
              FROM temp1 t1
              WHERE t1.id = t2.id
              FOR XML PATH (''))
             , 1, 1, '') from temp1 t2
group by id;

And we have our result:

Hope this helps!

This works:

wget -m -np -c --no-check-certificate -R "index.html*" "https://the-eye.eu/public/AudioBooks/Edgar%20Allan%20Poe%20-%2"

Why not update the files on the local file system instead? You can read/write files into your applications sandboxed area.

Other alternatives you may want to look into are Shared Perferences and using Cache Files (all described at the link above)

I did not have the issue when developing in localhost. However, once I published to a web server, the webservice was returning an empty (blank) result and I was seeing the error in my logs.

I fixed it by setting my ajax contentType to :

"application/json; charset=utf-8"

and using :

JSON.stringify()

on the object I was posting.

var postData = {data: myData};
$.ajax({
                type: "POST",
                url: "../MyService.asmx/MyMethod",
                data: JSON.stringify(postData), 
                contentType: "application/json; charset=utf-8",
                success: function (data) {
                    console.log(data);
                },
                dataType: "json"
            });

OK It's A Wrong Approach But If You Use it Like This :

compile "com.android.support:appcompat-v7:+"

Android Studio Will Use The Last Version It Has.

In My Case Was 26.0.0alpha-1.

You Can See The Used Version In External Libraries (In The Project View).

I Tried Everything But Couldn't Use Anything Above 26.0.0alpha-1, It Seems My IP Is Blocked By Google. Any Idea? Comment

According to Windows Dev Center:

TextBlock.IsTextSelectionEnabled property

[ Updated for UWP apps on Windows 10. For Windows 8.x articles, see the archive ]

Gets or sets a value that indicates whether text selection is enabled in the TextBlock, either through user action or calling selection-related API.

if I understand your question correctly, you want to know the row number during a conditional loop over an internal table. You can use the system variable sy-tabix if you work with internal tables. Please refer to the ABAP documentation if you need more information (especially the chapter on internal table processing).

Example:

LOOP AT itab INTO workarea
        WHERE tablefield = value.

     WRITE: 'This is row number ', sy-tabix.

ENDLOOP.

These helped me a lot: I wanted to save values from my gridview, and it was reloading my gridview /overriding my new values, as i have IsPostBack inside my PageLoad.

if (HttpContext.Current.Request["MYCLICKEDBUTTONID"] == null)
{
   //Do not reload the gridview.

}
else
{
   reload my gridview.
}

getdate() or getutcdate().

Dispatching and action inside of reducer seems occurs bug.

I made a simple counter example using useReducer which "INCREASE" is dispatched then "SUB" also does.

In the example I expected "INCREASE" is dispatched then also "SUB" does and, set cnt to -1 and then continue "INCREASE" action to set cnt to 0, but it was -1 ("INCREASE" was ignored)

See this: https://codesandbox.io/s/simple-react-context-example-forked-p7po7?file=/src/index.js:144-154

let listener = () => {
  console.log("test");
};
const middleware = (action) => {
  console.log(action);
  if (action.type === "INCREASE") {
    listener();
  }
};

const counterReducer = (state, action) => {
  middleware(action);
  switch (action.type) {
    case "INCREASE":
      return {
        ...state,
        cnt: state.cnt + action.payload
      };
    case "SUB":
      return {
        ...state,
        cnt: state.cnt - action.payload
      };
    default:
      return state;
  }
};

const Test = () => {
  const { cnt, increase, substract } = useContext(CounterContext);

  useEffect(() => {
    listener = substract;
  });

  return (
    <button
      onClick={() => {
        increase();
      }}
    >
      {cnt}
    </button>
  );
};

{type: "INCREASE", payload: 1}
{type: "SUB", payload: 1}
// expected: cnt: 0
// cnt = -1

to clarify a bit on dragon's answer (since it took me a while to figure out what to do with Handler.Callback):

Handler can be used to execute callbacks in the current or another thread, by passing it Messages. the Message holds data to be used from the callback. a Handler.Callback can be passed to the constructor of Handler in order to avoid extending Handler directly. thus, to execute some code via callback from the current thread:

Message message = new Message();
<set data to be passed to callback - eg message.obj, message.arg1 etc - here>

Callback callback = new Callback() {
    public boolean handleMessage(Message msg) {
        <code to be executed during callback>
    }
};

Handler handler = new Handler(callback);
handler.sendMessage(message);

EDIT: just realized there's a better way to get the same result (minus control of exactly when to execute the callback):

post(new Runnable() {
    @Override
    public void run() {
        <code to be executed during callback>
    }
});

In advance of my questions being answered, this is how I'd go about it:

Minimize the number of statements and the work they do issued in relative terms.

All scenarios assume you have a table of IDs (PURGE_IDS) to delete from TABLE_1, TABLE_2, etc.

Consider Using CREATE TABLE AS SELECT for really large deletes

If there's no concurrent activity, and you're deleting 30+ % of the rows in one or more of the tables, don't delete; perform a create table as select with the rows you wish to keep, and swap the new table out for the old table. INSERT /*+ APPEND */ ... NOLOGGING is surprisingly cheap if you can afford it. Even if you do have some concurrent activity, you may be able to use Online Table Redefinition to rebuild the table in-place.

Don't run DELETE statements you know won't delete any rows

If an ID value exists in at most one of the six tables, then keep track of which IDs you've deleted - and don't try to delete those IDs from any of the other tables.

CREATE TABLE TABLE1_PURGE NOLOGGING
AS 
SELECT ID FROM PURGE_IDS INNER JOIN TABLE_1 ON PURGE_IDS.ID = TABLE_1.ID;

DELETE FROM TABLE1 WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DELETE FROM PURGE_IDS WHERE ID IN (SELECT ID FROM TABLE1_PURGE);

DROP TABLE TABLE1_PURGE;

and repeat.

Manage Concurrency if you have to

Another way is to use PL/SQL looping over the tables, issuing a rowcount-limited delete statement. This is most likely appropriate if there's significant insert/update/delete concurrent load against the tables you're running the deletes against.

declare
  l_sql varchar2(4000);
begin
  for i in (select table_name from all_tables 
             where table_name in ('TABLE_1', 'TABLE_2', ...)
             order by table_name);
  loop
    l_sql := 'delete from ' || i.table_name || 
             ' where id in (select id from purge_ids) ' || 
             '   and rownum <= 1000000';
    loop
      commit;
      execute immediate l_sql;
      exit when sql%rowcount <> 1000000;  -- if we delete less than 1,000,000
    end loop;                             -- no more rows need to be deleted!
  end loop;
  commit;
end;

I'm using 4 break points but as ralph.m said each site is unique. You should experiment. There are no magic breakpoints due to so many devices, screens, and resolutions.

Here is what I use as a template. I'm checking the website for each breakpoint on different mobile devices and updating CSS for each element (ul, div, etc.) not displaying correctly for that breakpoint.

So far that was working on multiple responsive websites I've made.

/* SMARTPHONES PORTRAIT */
@media only screen and (min-width: 300px) {


}

/* SMARTPHONES LANDSCAPE */
@media only screen and (min-width: 480px) {


}

/* TABLETS PORTRAIT */
@media only screen and (min-width: 768px) {


}


/* TABLET LANDSCAPE / DESKTOP */
@media only screen and (min-width: 1024px) {


}    

UPDATE

As per September 2015, I'm using a better one. I find out that these media queries breakpoints match many more devices and desktop screen resolutions.

Having all CSS for desktop on style.css

All media queries on responsive.css: all CSS for responsive menu + media break points

@media only screen and (min-width: 320px) and (max-width: 479px){ ... }

@media only screen and (min-width: 480px) and (max-width: 767px){ ... }

@media only screen and (min-width: 768px) and (max-width: 991px){ ... }

@media only screen and (min-width: 992px){ ... }

Update 2019: As per Hugo comment below, I removed max-width 1999px because of the new very wide screens.

The short answer, or TL;DR

Basically, eval is used to evaluate a single dynamically generated Python expression, and exec is used to execute dynamically generated Python code only for its side effects.

eval and exec have these two differences:

1. eval accepts only a single expression, exec can take a code block that has Python statements: loops, try: except:, class and function/method definitions and so on.

   An expression in Python is whatever you can have as the value in a variable assignment:

   a_variable = (anything you can put within these parentheses is an expression)
   

2. eval returns the value of the given expression, whereas exec ignores the return value from its code, and always returns None (in Python 2 it is a statement and cannot be used as an expression, so it really does not return anything).

In versions 1.0 - 2.7, exec was a statement, because CPython needed to produce a different kind of code object for functions that used exec for its side effects inside the function.

In Python 3, exec is a function; its use has no effect on the compiled bytecode of the function where it is used.

Thus basically:

>>> a = 5
>>> eval('37 + a')   # it is an expression
42
>>> exec('37 + a')   # it is an expression statement; value is ignored (None is returned)
>>> exec('a = 47')   # modify a global variable as a side effect
>>> a
47
>>> eval('a = 47')  # you cannot evaluate a statement
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    a = 47
      ^
SyntaxError: invalid syntax

The compile in 'exec' mode compiles any number of statements into a bytecode that implicitly always returns None, whereas in 'eval' mode it compiles a single expression into bytecode that returns the value of that expression.

>>> eval(compile('42', '<string>', 'exec'))  # code returns None
>>> eval(compile('42', '<string>', 'eval'))  # code returns 42
42
>>> exec(compile('42', '<string>', 'eval'))  # code returns 42,
>>>                                          # but ignored by exec

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>', 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Actually the statement "eval accepts only a single expression" applies only when a string (which contains Python source code) is passed to eval. Then it is internally compiled to bytecode using compile(source, '<string>', 'eval') This is where the difference really comes from.

If a code object (which contains Python bytecode) is passed to exec or eval, they behave identically, excepting for the fact that exec ignores the return value, still returning None always. So it is possible use eval to execute something that has statements, if you just compiled it into bytecode before instead of passing it as a string:

>>> eval(compile('if 1: print("Hello")', '<string>', 'exec'))
Hello
>>>

works without problems, even though the compiled code contains statements. It still returns None, because that is the return value of the code object returned from compile.

In the 'eval' mode (and thus with the eval function if a string is passed in), the compile raises an exception if the source code contains statements or anything else beyond a single expression:

>>> compile('for i in range(3): print(i)', '<string>'. 'eval')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

The longer answer, a.k.a the gory details

exec and eval

The exec function (which was a statement in Python 2) is used for executing a dynamically created statement or program:

>>> program = '''
for i in range(3):
    print("Python is cool")
'''
>>> exec(program)
Python is cool
Python is cool
Python is cool
>>> 

The eval function does the same for a single expression, and returns the value of the expression:

>>> a = 2
>>> my_calculation = '42 * a'
>>> result = eval(my_calculation)
>>> result
84

exec and eval both accept the program/expression to be run either as a str, unicode or bytes object containing source code, or as a code object which contains Python bytecode.

If a str/unicode/bytes containing source code was passed to exec, it behaves equivalently to:

exec(compile(source, '<string>', 'exec'))

and eval similarly behaves equivalent to:

eval(compile(source, '<string>', 'eval'))

Since all expressions can be used as statements in Python (these are called the Expr nodes in the Python abstract grammar; the opposite is not true), you can always use exec if you do not need the return value. That is to say, you can use either eval('my_func(42)') or exec('my_func(42)'), the difference being that eval returns the value returned by my_func, and exec discards it:

>>> def my_func(arg):
...     print("Called with %d" % arg)
...     return arg * 2
... 
>>> exec('my_func(42)')
Called with 42
>>> eval('my_func(42)')
Called with 42
84
>>> 

Of the 2, only exec accepts source code that contains statements, like def, for, while, import, or class, the assignment statement (a.k.a a = 42), or entire programs:

>>> exec('for i in range(3): print(i)')
0
1
2
>>> eval('for i in range(3): print(i)')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print(i)
      ^
SyntaxError: invalid syntax

Both exec and eval accept 2 additional positional arguments - globals and locals - which are the global and local variable scopes that the code sees. These default to the globals() and locals() within the scope that called exec or eval, but any dictionary can be used for globals and any mapping for locals (including dict of course). These can be used not only to restrict/modify the variables that the code sees, but are often also used for capturing the variables that the executed code creates:

>>> g = dict()
>>> l = dict()
>>> exec('global a; a, b = 123, 42', g, l)
>>> g['a']
123
>>> l
{'b': 42}

(If you display the value of the entire g, it would be much longer, because exec and eval add the built-ins module as __builtins__ to the globals automatically if it is missing).

In Python 2, the official syntax for the exec statement is actually exec code in globals, locals, as in

>>> exec 'global a; a, b = 123, 42' in g, l

However the alternate syntax exec(code, globals, locals) has always been accepted too (see below).

compile

The compile(source, filename, mode, flags=0, dont_inherit=False, optimize=-1) built-in can be used to speed up repeated invocations of the same code with exec or eval by compiling the source into a code object beforehand. The mode parameter controls the kind of code fragment the compile function accepts and the kind of bytecode it produces. The choices are 'eval', 'exec' and 'single':

• 'eval' mode expects a single expression, and will produce bytecode that when run will return the value of that expression:

  >>> dis.dis(compile('a + b', '<string>', 'eval'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 RETURN_VALUE
  

• 'exec' accepts any kinds of python constructs from single expressions to whole modules of code, and executes them as if they were module top-level statements. The code object returns None:

  >>> dis.dis(compile('a + b', '<string>', 'exec'))
    1           0 LOAD_NAME                0 (a)
                3 LOAD_NAME                1 (b)
                6 BINARY_ADD
                7 POP_TOP                             <- discard result
                8 LOAD_CONST               0 (None)   <- load None on stack
               11 RETURN_VALUE                        <- return top of stack
  

• 'single' is a limited form of 'exec' which accepts a source code containing a single statement (or multiple statements separated by ;) if the last statement is an expression statement, the resulting bytecode also prints the repr of the value of that expression to the standard output(!).

  An if-elif-else chain, a loop with else, and try with its except, else and finally blocks is considered a single statement.

  A source fragment containing 2 top-level statements is an error for the 'single', except in Python 2 there is a bug that sometimes allows multiple toplevel statements in the code; only the first is compiled; the rest are ignored:

  In Python 2.7.8:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  >>> a
  5
  

  And in Python 3.4.2:

  >>> exec(compile('a = 5\na = 6', '<string>', 'single'))
  Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 1
      a = 5
          ^
  SyntaxError: multiple statements found while compiling a single statement
  

  This is very useful for making interactive Python shells. However, the value of the expression is not returned, even if you eval the resulting code.

Thus greatest distinction of exec and eval actually comes from the compile function and its modes.

In addition to compiling source code to bytecode, compile supports compiling abstract syntax trees (parse trees of Python code) into code objects; and source code into abstract syntax trees (the ast.parse is written in Python and just calls compile(source, filename, mode, PyCF_ONLY_AST)); these are used for example for modifying source code on the fly, and also for dynamic code creation, as it is often easier to handle the code as a tree of nodes instead of lines of text in complex cases.

While eval only allows you to evaluate a string that contains a single expression, you can eval a whole statement, or even a whole module that has been compiled into bytecode; that is, with Python 2, print is a statement, and cannot be evalled directly:

>>> eval('for i in range(3): print("Python is cool")')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<string>", line 1
    for i in range(3): print("Python is cool")
      ^
SyntaxError: invalid syntax

compile it with 'exec' mode into a code object and you can eval it; the eval function will return None.

>>> code = compile('for i in range(3): print("Python is cool")',
                   'foo.py', 'exec')
>>> eval(code)
Python is cool
Python is cool
Python is cool

If one looks into eval and exec source code in CPython 3, this is very evident; they both call PyEval_EvalCode with same arguments, the only difference being that exec explicitly returns None.

Syntax differences of exec between Python 2 and Python 3

One of the major differences in Python 2 is that exec is a statement and eval is a built-in function (both are built-in functions in Python 3). It is a well-known fact that the official syntax of exec in Python 2 is exec code [in globals[, locals]].

Unlike majority of the Python 2-to-3 porting guides seem to suggest, the exec statement in CPython 2 can be also used with syntax that looks exactly like the exec function invocation in Python 3. The reason is that Python 0.9.9 had the exec(code, globals, locals) built-in function! And that built-in function was replaced with exec statement somewhere before Python 1.0 release.

Since it was desirable to not break backwards compatibility with Python 0.9.9, Guido van Rossum added a compatibility hack in 1993: if the code was a tuple of length 2 or 3, and globals and locals were not passed into the exec statement otherwise, the code would be interpreted as if the 2nd and 3rd element of the tuple were the globals and locals respectively. The compatibility hack was not mentioned even in Python 1.4 documentation (the earliest available version online); and thus was not known to many writers of the porting guides and tools, until it was documented again in November 2012:

The first expression may also be a tuple of length 2 or 3. In this case, the optional parts must be omitted. The form exec(expr, globals) is equivalent to exec expr in globals, while the form exec(expr, globals, locals) is equivalent to exec expr in globals, locals. The tuple form of exec provides compatibility with Python 3, where exec is a function rather than a statement.

Yes, in CPython 2.7 that it is handily referred to as being a forward-compatibility option (why confuse people over that there is a backward compatibility option at all), when it actually had been there for backward-compatibility for two decades.

Thus while exec is a statement in Python 1 and Python 2, and a built-in function in Python 3 and Python 0.9.9,

>>> exec("print(a)", globals(), {'a': 42})
42

has had identical behaviour in possibly every widely released Python version ever; and works in Jython 2.5.2, PyPy 2.3.1 (Python 2.7.6) and IronPython 2.6.1 too (kudos to them following the undocumented behaviour of CPython closely).

What you cannot do in Pythons 1.0 - 2.7 with its compatibility hack, is to store the return value of exec into a variable:

Python 2.7.11+ (default, Apr 17 2016, 14:00:29) 
[GCC 5.3.1 20160413] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> a = exec('print(42)')
  File "<stdin>", line 1
    a = exec('print(42)')
           ^
SyntaxError: invalid syntax

(which wouldn't be useful in Python 3 either, as exec always returns None), or pass a reference to exec:

>>> call_later(exec, 'print(42)', delay=1000)
  File "<stdin>", line 1
    call_later(exec, 'print(42)', delay=1000)
                  ^
SyntaxError: invalid syntax

Which a pattern that someone might actually have used, though unlikely;

Or use it in a list comprehension:

>>> [exec(i) for i in ['print(42)', 'print(foo)']
  File "<stdin>", line 1
    [exec(i) for i in ['print(42)', 'print(foo)']
        ^
SyntaxError: invalid syntax

which is abuse of list comprehensions (use a for loop instead!).

Not possible without assigning height value to div.

Add this

body, html{height:100%}
div{height:100%}
table{background:green; width:450px}    ?

I had this error, I looked into a log file C:\...\mysql\data\VM-IIS-Server.err and found this

2016-06-07 17:56:07 160c  InnoDB: Error: unable to create temporary file; errno: 2

The first line says "unable to create temporary file", it sounds like "insufficient privileges", first I tried to give access to mysql folder for my current user - no effect, then after some wandering around I came up to control panel->Administration->Services->Right Clicked MysqlService->Properties->Log On, switched to "This account", entered my username/password, clicked OK, and it woked!

I just found this quite impressive tutorial about jquery to javascript conversion from Jeffrey Way on Jan 19th 2012 *Copyright © 2014 Envato* :

http://net.tutsplus.com/tutorials/javascript-ajax/from-jquery-to-javascript-a-reference/

Whether we like it or not, more and more developers are being introduced to the world of JavaScript through jQuery first. In many ways, these newcomers are the lucky ones. They have access to a plethora of new JavaScript APIs, which make the process of DOM traversal (something that many folks depend on jQuery for) considerably easier. Unfortunately, they don’t know about these APIs!

In this article, we’ll take a variety of common jQuery tasks, and convert them to both modern and legacy JavaScript.

I proposed it in a comment to OP, and after his suggestion, i publish it has an answer for everyone to refer to.

Also, Jeffrey Way mentioned about his inspiration witch seems to be a good primer for understanding : http://sharedfil.es/js-48hIfQE4XK.html

Has a teaser, this document comparison of jQuery to javascript :

$(document).ready(function() {
  // code…
});

document.addEventListener("DOMContentLoaded", function() {
  // code…
});

$("a").click(function() {
  // code…
})

[].forEach.call(document.querySelectorAll("a"), function(el) {
  el.addEventListener("click", function() {
    // code…
  });
});

You should take a look.

I prefer:

class MTest extends Activity implements OnClickListener {
    public void onCreate(Bundle savedInstanceState) {
    ...
    Button b1 = (Button) findViewById(R.id.b1);
    Button b2 = (Button) findViewById(R.id.b2);
    b1.setOnClickListener(this);
    b2.setOnClickListener(this);
    ...
}

And then:

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.b1:
            ....
            break;
        case R.id.b2:
            ....
            break;
    }   
}

Switch-case is easier to maintain than if-else, and this implementation doesn't require making many class variables.

I found it's better to set the width and height to 0px. Otherwise, IE10 ignores the padding defined on the field -- padding-right -- which was intended to keep the text from typing over the 'X' icon that I overlayed on the input field. I'm guessing that IE10 is internally applying the padding-right of the input to the ::--ms-clear pseudo element, and hiding the pseudo element does not restore the padding-right value to the input.

This worked better for me:

.someinput::-ms-clear {
  width : 0;
  height: 0;
}

In order to start a service in its own process, you must specify the following in the xml declaration.

<service
  android:name="WordService"
  android:process=":my_process" 
  android:icon="@drawable/icon"
  android:label="@string/service_name"
  >
</service>

SELECT * FROM NOTES ORDER BY UPPER(title)              

This is a quite an old post which is still useful. All the solutions that proposes these two had little condition that not suite all:

• SpringBeanAutowiringSupport.processInjectionBasedOnCurrentContext(this); This assumes or requires it to be a spring - web based project
• AutowiringSpringBeanJobFactory based approach mentioned in previous answer is very helpful, but the answer is specific to those who don't use pure vanilla quartz api but rather Spring's wrapper for the quartz to do the same.

If you want to remain with pure Quartz implementation for scheduling(Quartz with Autowiring capabilities with Spring), I was able to do it as follows:

I was looking to do it quartz way as much as possible and thus little hack proves helpful.

 public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory{

    private AutowireCapableBeanFactory beanFactory;

    public AutowiringSpringBeanJobFactory(final ApplicationContext applicationContext){
        beanFactory = applicationContext.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        beanFactory.initializeBean(job, job.getClass().getName());
        return job;
    }
}


@Configuration
public class SchedulerConfig {   
    @Autowired private ApplicationContext applicationContext;

    @Bean
    public AutowiringSpringBeanJobFactory getAutowiringSpringBeanJobFactory(){
        return new AutowiringSpringBeanJobFactory(applicationContext);
    }
}


private void initializeAndStartScheduler(final Properties quartzProperties)
            throws SchedulerException {
        //schedulerFactory.initialize(quartzProperties);
        Scheduler quartzScheduler = schedulerFactory.getScheduler();

        //Below one is the key here. Use the spring autowire capable job factory and inject here
        quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory);
        quartzScheduler.start();
    }

quartzScheduler.setJobFactory(autowiringSpringBeanJobFactory); gives us an autowired job instance. Since AutowiringSpringBeanJobFactory implicitly implements a JobFactory, we now enabled an auto-wireable solution. Hope this helps!

First up, you seem to be mixing table variables and tables.

Either way, You can't pass in the table's name like that. You would have to use dynamic TSQL to do that.

If you just want to declare a table variable:

CREATE PROC sp_createATable 
  @name        VARCHAR(10), 
  @properties  VARCHAR(500) 
AS 
  declare @tablename TABLE
  ( 
    id  CHAR(10)  PRIMARY KEY 
  ); 

The fact that you want to create a stored procedure to dynamically create tables might suggest your design is wrong.

This works fine

<?php
      $con=mysqli_connect("localhost","my_user","my_password","my_db");
      $con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
      $con->query("SET time_zone = '+05:30'");
      $con->query("SET @@session.time_zone = '+05:30'");
?>

Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator and removing the item there.

Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
  Item blah = iter.next();
  if(...) {
    iter.remove(); // Removes the 'current' item
  }
}
