The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.

The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

fc. fc is better at handling large files (> 4 GBytes) than Cygwin's diff.

def longestWord(some_list): 
    count = 0    #You set the count to 0
    for i in some_list: # Go through the whole list
        if len(i) > count: #Checking for the longest word(string)
            count = len(i)
            word = i
    return ("the longest string is " + word)

or much easier:

max(some_list , key = len)

maybe you forget to add parameter dataType:'json' in your $.ajax

$.ajax({
   type: "POST",
   dataType: "json",
   url: url,
   data: { get_member: id },
   success: function( response ) 
   { 
     //some action here
   },
   error: function( error )
   {
     alert( error );
   }
});

You asked if it is possible to change the circular dependency checking in those slf4j classes.

The simple answer is no.

• It is unconditional ... as implemented.
• It is implemented in a static initializer block ... so you can't override the implementation, and you can't stop it happening.

So the only way to change this would be to download the source code, modify the core classes to "fix" them, build and use them. That is probably a bad idea (in general) and probably not solution in this case; i.e. you risk triggering the stack overflow problem that the message warns about.

Reference:

• The source code.

The real solution (as you identified in your Answer) is to use the right JARs. My understanding is that the circularity that was detected is real and potentially problematic ... and unnecessary.

Others have pointed out the error in your existing code, but I'd like to take two steps further. Firstly, assuming you're using Java 1.5+, you can achieve greater readability using the enhanced for loop:

Customer findCustomerByid(int id){    
    for (Customer customer : customers) {
        if (customer.getId() == id) {
            return customer;
        }
    }
    return null; 
}

This has also removed the micro-optimisation of returning null before looping - I doubt that you'll get any benefit from it, and it's more code. Likewise I've removed the exists flag: returning as soon as you know the answer makes the code simpler.

Note that in your original code I think you had a bug. Having found that the customer at index i had the right ID, you then returned the customer at index id - I doubt that this is really what you intended.

Secondly, if you're going to do a lot of lookups by ID, have you considered putting your customers into a Map<Integer, Customer>?

Angular comes with a limitTo:limit filter, it support limiting first x items and last x items:

<div ng-repeat="item in items|limitTo:4">{{item}}</div>

std::string trimmed(std::string str ) {
if(str.length() == 0 ) { return "" ; }
else if ( str == std::string(" ") ) { return "" ; } 
else {
    while(str.at(0) == ' ') { str.erase(0, 1);}
    while(str.at(str.length()-1) == ' ') { str.pop_back() ; }
    return str ;
    } 
}

DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

//here ds is dataset
DatTable dt = ds.Table[0]; /// table of dataset

Give the textbox an id of "txtValue" and change the input button declaration to the following:

<input type="button" value="submit" onclick="verifyorder(document.getElementById('txtValue').value)" />

push does not return the array, but the length of it (docs), so what you are doing is replacing the array with its length, losing the only reference to it that you had. Try this:

import {ADD_ITEM} from '../Actions/UserActions'
const initialUserState = {

    arr:[]
}

export default function userState(state = initialUserState, action){
     console.log(arr);
     switch (action.type){
        case ADD_ITEM :
          return { 
             ...state,
             arr:[...state.arr, action.newItem]
        }

        default:return state
     }
}

The first thing you need to understand is that when you pass something to a function, that something is copied to the function's arguments.

Suppose you have the following:

void swap1(int a, int b) {
    int temp = a;
    a = b;
    b = temp;
    assert(a == 17);
    assert(b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap1(x, y);
assert(x == 42);
assert(y == 17);
// no, they're not swapped!

The original variables will not be swapped, because their values are copied into the function's arguments. The function then proceeds to swap the values of those arguments, and then returns. The original values are not changed, because the function only swaps its own private copies.

Now how do we work around this? The function needs a way to refer to the original variables, not copies of their values. How can we refer to other variables in C? Using pointers.

If we pass pointers to our variables into the function, the function can swap the values in our variables, instead of its own argument copies.

void swap2(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
swap2(&x, &y); // give the function pointers to our variables
assert(x == 17);
assert(y == 42);
// yes, they're swapped!

Notice how inside the function we're not assigning to the pointers, but assigning to what they point to. And the pointers point to our variables x and y. The function is changing directly the values stored in our variables through the pointers we give it. And that's exactly what we needed.

Now what happens if we have two pointer variables and want to swap the pointers themselves (as opposed to the values they point to)? If we pass pointers, the pointers will simply be copied (not the values they point to) to the arguments.

void swap3(int* a, int* b) {
    int* temp = a;
    a = b;
    b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}
void swap4(int* a, int* b) {
    int temp = *a;
    *a = *b;
    *b = temp;
    assert(*a == 17);
    assert(*b == 42);
    // they're swapped!
}

int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap3(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 42);
assert(y == 17);
// Didn't swap anything!
swap4(xp, yp);
assert(xp == &x);
assert(yp == &y);
assert(x == 17);
assert(y == 42);
// Swapped the stored values instead!

The function swap3 only swaps its own private copies of our pointers that it gets in its arguments. It's the same issue we had with swap1. And swap4 is changing the values our variables point to, not the pointers! We're giving the function a means to refer to the variables x and y but we want them to refer to xp and yp.

How do we do that? We pass it their addresses!

void swap5(int** a, int** b) {
    int* temp = *a;
    *a = *b;
    *b = temp;
    assert(**a == 17);
    assert(**b == 42);
    // they're swapped!
}


int x = 42;
int y = 17;
int* xp = &x;
int* yp = &y;
swap5(&xp, &yp);
assert(xp == &y);
assert(yp == &x);
assert(x == 42);
assert(y == 17);
// swapped only the pointers variables

This way it swaps our pointer variables (notice how xp now points to y) but not the values they point to. We gave it a way to refer to our pointer variables, so it can change them!

By now it should be easy to understand how to swap two strings in the form of char* variables. The swap function needs to receive pointers to char*.

void swapStrings(char** a, char** b){
    char *temp = *a;
    *a = *b;
    *b = temp;
    assert(strcmp(*a, "world") == 0);
    assert(strcmp(*b, "Hello") == 0);
}

char* x = "Hello";
char* y = "world";
swapStrings(&x, &y);
assert(strcmp(x, "world") == 0);
assert(strcmp(y, "Hello") == 0);

an idea ...

• write these in the ThisWorkbook module
• close and open the workbook

    Public LastCell As Range

    Private Sub Workbook_Open()

        Set LastCell = ActiveCell

    End Sub

    Private Sub Workbook_SheetSelectionChange(ByVal Sh As Object, ByVal Target As Range)

        Set oa = LastCell.Comment

        If Not oa Is Nothing Then
        LastCell.Comment.Delete
        End If

        Target.AddComment Target.Address
        Target.Comment.Visible = True
        Set LastCell = ActiveCell

    End Sub

The faster way for your case is:

    jTable.repaint(); // Repaint all the component (all Cells).

The optimized way when one or few cell change:

    ((AbstractTableModel) jTable.getModel()).fireTableCellUpdated(x, 0); // Repaint one cell.

I highly recommend the reading of a lecture in SciPy-lectures organization:

https://scipy-lectures.org/intro/language/reusing_code.html

It explains all the commented doubts.

But, new paths can be easily added and avoiding duplication with the following code:

import sys
new_path = 'insert here the new path'

if new_path not in sys.path:
    sys.path.append(new_path)
import funcoes_python #Useful python functions saved in a different script

You can use switch on strings. What you need is table of strings, check every string

char** strings[4] = {"Banana", "Watermelon", "Apple", "Orange"};

unsigned get_case_string(char* str, char** _strings, unsigned n)
{
    while(n)
    {
        n--
        if(strcmp(str, _strings[n]) == 0) return n;
    }
    return 0;
}

unsigned index = get_case_string("Banana", strings, 4);

switch(index)
{
    case 1: break;/*Found string `Banana`*/
    default: /*No string*/
}

Use this

DELETE FROM `articles`, `comments` 
USING `articles`,`comments` 
WHERE `comments`.`article_id` = `articles`.`id` AND `articles`.`id` = 4

or

DELETE `articles`, `comments` 
FROM `articles`, `comments` 
WHERE `comments`.`article_id` = `articles`.`id` AND `articles`.`id` = 4

-- Change the starting value of the sequence

ALTER SEQUENCE project_id_seq RESTART 3000;

Same but dynamic :

SELECT SETVAL('project_id_seq', (SELECT MAX(id) + 1 FROM project));

I agree the use of a SELECT is disturbing but it works.

Apache Commons IO's FileUtils offers FileUtils.deleteQuietly:

Deletes a file, never throwing an exception. If file is a directory, delete it and all sub-directories. The difference between File.delete() and this method are:

• A directory to be deleted does not have to be empty.
• No exceptions are thrown when a file or directory cannot be deleted.

This offers a one-liner delete call that won't complain if the file fails to be deleted:

FileUtils.deleteQuietly(new File("test.txt"));

FYI: You could get a similar behavior to what you want by creating extension methods for the interface. The extension method would be a shared, non overridable static behavior. However, unfortunately, this static method would not be part of the contract.

Never call setState inside render method

You should never ever call setState inside the render method. Why? calling setState eventually fires the render method again. That means you are calling setState (mentioned in your render block) in a loop that would never end. The correct way to do that is by using componentDidMount hook in React, like so:

class CowtanApp extends Component {
  state = {
     timePassed: false
  }

  componentDidMount () {
     setTimeout(() => this.setState({timePassed: true}), 1000)
  }

  render () {
    return this.state.timePassed ? (
        <NavigatorIOS
          style = {styles.container}
          initialRoute = {{
            component: LoginPage,
            title: 'Sign In',
        }}/>
    ) : <LoadingPage/>
  }
}

PS Use ternary operators for cleaner, shorter and readable code.

Just worked out for another solution as above example have bug( somewhere error ) for me. Variation from the selected answer.

html,body {
    height: 100%
}

#nonFooter {
    min-height: 100%;
    position:relative;
    /* Firefox */
    min-height: -moz-calc(100% - 30px);
    /* WebKit */
    min-height: -webkit-calc(100% - 30px);
    /* Opera */
    min-height: -o-calc(100% - 30px);
    /* Standard */
    min-height: calc(100% - 30px);
}

#footer {
    height:30px;
    margin: 0;
    clear: both;
    width:100%;
    position: relative;
}

for html layout

<body>
    <div id="nonFooter">header,middle,left,right,etc</div>
    <div id="footer"></div>
</body>

Well this way don't support old browser however its acceptable for old browser to scrolldown 30px to view the footer

In Bash you can do it by enabling the extglob option, like this (replace ls with cp and add the target directory, of course)

~/foobar> shopt extglob
extglob        off
~/foobar> ls
abar  afoo  bbar  bfoo
~/foobar> ls !(b*)
-bash: !: event not found
~/foobar> shopt -s extglob  # Enables extglob
~/foobar> ls !(b*)
abar  afoo
~/foobar> ls !(a*)
bbar  bfoo
~/foobar> ls !(*foo)
abar  bbar

You can later disable extglob with

shopt -u extglob

The preflight is being triggered by your Content-Type of application/json. The simplest way to prevent this is to set the Content-Type to be text/plain in your case. application/x-www-form-urlencoded & multipart/form-data Content-Types are also acceptable, but you'll of course need to format your request payload appropriately.

If you are still seeing a preflight after making this change, then Angular may be adding an X-header to the request as well.

Or you might have headers (Authorization, Cache-Control...) that will trigger it, see:

Here is my code. It'll open given url in default browser (cross platform solution).

import java.awt.Desktop;
import java.io.IOException;
import java.net.URI;
import java.net.URISyntaxException;

public class Browser {
    public static void main(String[] args) {
        String url = "http://www.google.com";

        if(Desktop.isDesktopSupported()){
            Desktop desktop = Desktop.getDesktop();
            try {
                desktop.browse(new URI(url));
            } catch (IOException | URISyntaxException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }else{
            Runtime runtime = Runtime.getRuntime();
            try {
                runtime.exec("xdg-open " + url);
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
}

First Method

 View someView = findViewById(R.id.randomViewInMainLayout);// get Any child View

  // Find the root view
  View root = someView.getRootView()

  // Set the color
  root.setBackgroundColor(getResources().getColor(android.R.color.red));

Second Method

Add this single line after setContentView(...);

getWindow().getDecorView().setBackgroundColor(Color.WHITE);

Third Method

set background color to the rootView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#FFFFFF"
android:id="@+id/rootView"
</LinearLayout>

Important Thing

rootView.setBackgroundColor(0xFF00FF00); //after 0x the other four pairs are alpha,red,green,blue color. 

Make a class that will fit table cell width to content

.table td.fit, 
.table th.fit {
    white-space: nowrap;
    width: 1%;
}

you just need to add a default constructor to your class to look like this:

class name {
  public:
    string first;
    string last;

  name() {
  }

  name(string a, string b){
    first = a;
    last = b;
  }
};

Why not a/b/(c|d|e)? I just tried with Saxon XML library (wrapped up nicely with some Clojure goodness), and it seems to work. abc.xml is the doc described by OP.

(require '[saxon :as xml])
(def abc-doc (xml/compile-xml (slurp "abc.xml")))
(xml/query "a/b/(c|d|e)" abc-doc)
=> (#<XdmNode <c>C1</c>>
    #<XdmNode <d>D1</d>>
    #<XdmNode <e>E1</e>>
    #<XdmNode <c>C2</c>>
    #<XdmNode <d>D2</d>>
    #<XdmNode <e>E1</e>>)

The

compile 'com.google.zxing:core:2.3.0'

unfortunately didn't work for me.

This is what worked for me:

dependencies {
   compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
   compile 'com.google.zxing:core:3.2.0'
}

This is going to be largely dependent on the RDBMS you're using, and whether a .NET option even exists for that RDBMS.

If you're using SQL Server, use the SqlBulkCopy class.

For other database vendors, try googling for them specifically. For example a search for ".NET Bulk insert into Oracle" turned up some interesting results, including this link back to Stack Overflow: Bulk Insert to Oracle using .NET.

Python 3.4 includes a new module: tracemalloc. It provides detailed statistics about which code is allocating the most memory. Here's an example that displays the top three lines allocating memory.

from collections import Counter
import linecache
import os
import tracemalloc

def display_top(snapshot, key_type='lineno', limit=3):
    snapshot = snapshot.filter_traces((
        tracemalloc.Filter(False, "<frozen importlib._bootstrap>"),
        tracemalloc.Filter(False, "<unknown>"),
    ))
    top_stats = snapshot.statistics(key_type)

    print("Top %s lines" % limit)
    for index, stat in enumerate(top_stats[:limit], 1):
        frame = stat.traceback[0]
        # replace "/path/to/module/file.py" with "module/file.py"
        filename = os.sep.join(frame.filename.split(os.sep)[-2:])
        print("#%s: %s:%s: %.1f KiB"
              % (index, filename, frame.lineno, stat.size / 1024))
        line = linecache.getline(frame.filename, frame.lineno).strip()
        if line:
            print('    %s' % line)

    other = top_stats[limit:]
    if other:
        size = sum(stat.size for stat in other)
        print("%s other: %.1f KiB" % (len(other), size / 1024))
    total = sum(stat.size for stat in top_stats)
    print("Total allocated size: %.1f KiB" % (total / 1024))


tracemalloc.start()

counts = Counter()
fname = '/usr/share/dict/american-english'
with open(fname) as words:
    words = list(words)
    for word in words:
        prefix = word[:3]
        counts[prefix] += 1
print('Top prefixes:', counts.most_common(3))

snapshot = tracemalloc.take_snapshot()
display_top(snapshot)

And here are the results:

Top prefixes: [('con', 1220), ('dis', 1002), ('pro', 809)]
Top 3 lines
#1: scratches/memory_test.py:37: 6527.1 KiB
    words = list(words)
#2: scratches/memory_test.py:39: 247.7 KiB
    prefix = word[:3]
#3: scratches/memory_test.py:40: 193.0 KiB
    counts[prefix] += 1
4 other: 4.3 KiB
Total allocated size: 6972.1 KiB

When is a memory leak not a leak?

That example is great when the memory is still being held at the end of the calculation, but sometimes you have code that allocates a lot of memory and then releases it all. It's not technically a memory leak, but it's using more memory than you think it should. How can you track memory usage when it all gets released? If it's your code, you can probably add some debugging code to take snapshots while it's running. If not, you can start a background thread to monitor memory usage while the main thread runs.

Here's the previous example where the code has all been moved into the count_prefixes() function. When that function returns, all the memory is released. I also added some sleep() calls to simulate a long-running calculation.

from collections import Counter
import linecache
import os
import tracemalloc
from time import sleep


def count_prefixes():
    sleep(2)  # Start up time.
    counts = Counter()
    fname = '/usr/share/dict/american-english'
    with open(fname) as words:
        words = list(words)
        for word in words:
            prefix = word[:3]
            counts[prefix] += 1
            sleep(0.0001)
    most_common = counts.most_common(3)
    sleep(3)  # Shut down time.
    return most_common


def main():
    tracemalloc.start()

    most_common = count_prefixes()
    print('Top prefixes:', most_common)

    snapshot = tracemalloc.take_snapshot()
    display_top(snapshot)


def display_top(snapshot, key_type='lineno', limit=3):
    snapshot = snapshot.filter_traces((
        tracemalloc.Filter(False, "<frozen importlib._bootstrap>"),
        tracemalloc.Filter(False, "<unknown>"),
    ))
    top_stats = snapshot.statistics(key_type)

    print("Top %s lines" % limit)
    for index, stat in enumerate(top_stats[:limit], 1):
        frame = stat.traceback[0]
        # replace "/path/to/module/file.py" with "module/file.py"
        filename = os.sep.join(frame.filename.split(os.sep)[-2:])
        print("#%s: %s:%s: %.1f KiB"
              % (index, filename, frame.lineno, stat.size / 1024))
        line = linecache.getline(frame.filename, frame.lineno).strip()
        if line:
            print('    %s' % line)

    other = top_stats[limit:]
    if other:
        size = sum(stat.size for stat in other)
        print("%s other: %.1f KiB" % (len(other), size / 1024))
    total = sum(stat.size for stat in top_stats)
    print("Total allocated size: %.1f KiB" % (total / 1024))


main()

When I run that version, the memory usage has gone from 6MB down to 4KB, because the function released all its memory when it finished.

Top prefixes: [('con', 1220), ('dis', 1002), ('pro', 809)]
Top 3 lines

    result = [(key(elem), i, elem) for i, elem in zip(range(0, -n, -1), it)]

Now here's a version inspired by another answer that starts a second thread to monitor memory usage.

from collections import Counter
import linecache

from datetime import datetime

from resource import getrusage, RUSAGE_SELF

            command_queue.get(timeout=poll_interval)
            if snapshot is not None:
                print(datetime.now())
                display_top(snapshot)

            return
        except Empty:

The resource module lets you check the current memory usage, and save the snapshot from the peak memory usage. The queue lets the main thread tell the memory monitor thread when to print its report and shut down. When it runs, it shows the memory being used by the list() call:

If you're on Linux, you may find /proc/self/statm more useful than the resource module.

This is a block element, in order for it to be able to receive focus, you need to add tabindex attribute to it, as in

<div id="myID" tabindex="1"></div>

Tabindex will allow this element to receive focus. Use tabindex="-1" (or indeed, just get rid of the attribute alltogether) to disallow this behaviour.

And then you can simply

if ($("#myID").is(":focus")) {...}

Or use the

$(document.activeElement)

As been suggested previously.

Form.Close() is use to close an instance of a Form with in .NET application it does not kill the entire application. Application.exit() kills your application.

I got the same error message because I had a function with a parameter named with a reserved word.

   public int SaveDelegate(MyModel.Delegate delegate)

Renaming the variable delegate solved the problem.

Example code:

a = pd.Series([1,2,3,4], index=[7,2,8,9])
b = pd.Series([5,6,7,8], index=[7,2,8,9])
data = pd.DataFrame({'a': a,'b':b, 'idx_col':a.index})

Pandas allows you to create a DataFrame from a dict with Series as the values and the column names as the keys. When it finds a Series as a value, it uses the Series index as part of the DataFrame index. This data alignment is one of the main perks of Pandas. Consequently, unless you have other needs, the freshly created DataFrame has duplicated value. In the above example, data['idx_col'] has the same data as data.index.

In Solaris OS I used this command:

$ who am i     # Remember to use it with space.

On Linux- Someone already answered this in comments.

$ whoami       # Without space

I had the same problem. Installed mingw using the installer provided at http://tdm-gcc.tdragon.net/ . It adds the correct environment variables to path when installing mingw (No need to edit the path variable manually). That did the trick for me.

To interpret a byte sequence as a text, you have to know the corresponding character encoding:

unicode_text = bytestring.decode(character_encoding)

Example:

>>> b'\xc2\xb5'.decode('utf-8')
'µ'

ls command may produce output that can't be interpreted as text. File names on Unix may be any sequence of bytes except slash b'/' and zero b'\0':

>>> open(bytes(range(0x100)).translate(None, b'\0/'), 'w').close()

Trying to decode such byte soup using utf-8 encoding raises UnicodeDecodeError.

It can be worse. The decoding may fail silently and produce mojibake if you use a wrong incompatible encoding:

>>> '—'.encode('utf-8').decode('cp1252')
'—'

The data is corrupted but your program remains unaware that a failure has occurred.

In general, what character encoding to use is not embedded in the byte sequence itself. You have to communicate this info out-of-band. Some outcomes are more likely than others and therefore chardet module exists that can guess the character encoding. A single Python script may use multiple character encodings in different places.

ls output can be converted to a Python string using os.fsdecode() function that succeeds even for undecodable filenames (it uses sys.getfilesystemencoding() and surrogateescape error handler on Unix):

import os
import subprocess

output = os.fsdecode(subprocess.check_output('ls'))

To get the original bytes, you could use os.fsencode().

If you pass universal_newlines=True parameter then subprocess uses locale.getpreferredencoding(False) to decode bytes e.g., it can be cp1252 on Windows.

To decode the byte stream on-the-fly, io.TextIOWrapper() could be used: example.

Different commands may use different character encodings for their output e.g., dir internal command (cmd) may use cp437. To decode its output, you could pass the encoding explicitly (Python 3.6+):

output = subprocess.check_output('dir', shell=True, encoding='cp437')

The filenames may differ from os.listdir() (which uses Windows Unicode API) e.g., '\xb6' can be substituted with '\x14'—Python's cp437 codec maps b'\x14' to control character U+0014 instead of U+00B6 (¶). To support filenames with arbitrary Unicode characters, see Decode PowerShell output possibly containing non-ASCII Unicode characters into a Python string

You can use binding expressions:

private void ComboBox_Loaded(object sender, RoutedEventArgs e)
{
    ((ComboBox)sender).GetBindingExpression(ComboBox.ItemsSourceProperty)
                      .UpdateTarget();
}

But as Blindmeis noted you can also fire change notifications, further if your collection implements INotifyCollectionChanged (for example implemented in the ObservableCollection<T>) it will synchronize so you do not need to do any of this.

If you display the HTML Source Editing toolbar there is a "Format the Whole Document" button as well

I think people saying stderr should be used only for error messages is misleading.

It should also be used for informative messages that are meant for the user running the command and not for any potential downstream consumers of the data (i.e. if you run a shell pipe chaining several commands you do not want informative messages like "getting item 30 of 42424" to appear on stdout as they will confuse the consumer, but you might still want the user to see them.

See this for historical rationale:

"All programs placed diagnostics on the standard output. This had always caused trouble when the output was redirected into a ?le, but became intolerable when the output was sent to an unsuspecting process. Nevertheless, unwilling to violate the simplicity of the standard-input-standard-output model, people tolerated this state of affairs through v6. Shortly thereafter Dennis Ritchie cut the Gordian knot by introducing the standard error ?le. That was not quite enough. With pipelines diagnostics could come from any of several programs running simultaneously. Diagnostics needed to identify themselves."

Cancelling Angular $http Ajax with the timeout property doesn't work in Angular 1.3.15. For those that cannot wait for this to be fixed I'm sharing a jQuery Ajax solution wrapped in Angular.

The solution involves two services:

• HttpService (a wrapper around the jQuery Ajax function);
• PendingRequestsService (tracks the pending/open Ajax requests)

Here goes the PendingRequestsService service:

    (function (angular) {
    'use strict';
    var app = angular.module('app');
    app.service('PendingRequestsService', ["$log", function ($log) {            
        var $this = this;
        var pending = [];
        $this.add = function (request) {
            pending.push(request);
        };
        $this.remove = function (request) {
            pending = _.filter(pending, function (p) {
                return p.url !== request;
            });
        };
        $this.cancelAll = function () {
            angular.forEach(pending, function (p) {
                p.xhr.abort();
                p.deferred.reject();
            });
            pending.length = 0;
        };
    }]);})(window.angular);

The HttpService service:

     (function (angular) {
        'use strict';
        var app = angular.module('app');
        app.service('HttpService', ['$http', '$q', "$log", 'PendingRequestsService', function ($http, $q, $log, pendingRequests) {
            this.post = function (url, params) {
                var deferred = $q.defer();
                var xhr = $.ASI.callMethod({
                    url: url,
                    data: params,
                    error: function() {
                        $log.log("ajax error");
                    }
                });
                pendingRequests.add({
                    url: url,
                    xhr: xhr,
                    deferred: deferred
                });            
                xhr.done(function (data, textStatus, jqXhr) {                                    
                        deferred.resolve(data);
                    })
                    .fail(function (jqXhr, textStatus, errorThrown) {
                        deferred.reject(errorThrown);
                    }).always(function (dataOrjqXhr, textStatus, jqXhrErrorThrown) {
                        //Once a request has failed or succeeded, remove it from the pending list
                        pendingRequests.remove(url);
                    });
                return deferred.promise;
            }
        }]);
    })(window.angular);

Later in your service when you are loading data you would use the HttpService instead of $http:

(function (angular) {

    angular.module('app').service('dataService', ["HttpService", function (httpService) {

        this.getResources = function (params) {

            return httpService.post('/serverMethod', { param: params });

        };
    }]);

})(window.angular);

Later in your code you would like to load the data:

(function (angular) {

var app = angular.module('app');

app.controller('YourController', ["DataService", "PendingRequestsService", function (httpService, pendingRequestsService) {

    dataService
    .getResources(params)
    .then(function (data) {    
    // do stuff    
    });    

    ...

    // later that day cancel requests    
    pendingRequestsService.cancelAll();
}]);

})(window.angular);

Make sure you're in your project

1. Open the Preferences, by clicking File > Settings (on Mac, Android Studio > Preferences).
2. In the left pane, click Build, Execution, Deployment >> Gradle.
3. Uncheck/disable the Offline work checkbox.
4. Click Apply or OK.

I wrote the following code to convert an image from sdcard to a Base64 encoded string to send as a JSON object.And it works great:

String filepath = "/sdcard/temp.png";
File imagefile = new File(filepath);
FileInputStream fis = null;
try {
    fis = new FileInputStream(imagefile);
    } catch (FileNotFoundException e) {
    e.printStackTrace();
}

Bitmap bm = BitmapFactory.decodeStream(fis);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100 , baos);    
byte[] b = baos.toByteArray(); 
encImage = Base64.encodeToString(b, Base64.DEFAULT);

There are two options. Ayman's approach is the most simple, but I would add one extra note to it. You should really cache jQuery selections, there is no reason to call $("#input-field-id") twice:

var input = $( "#input-field-id" );
input.val( input.val() + "more text" );

The other option, .val() can also take a function as an argument. This has the advantange of easily working on multiple inputs:

$( "input" ).val( function( index, val ) {
    return val + "more text";
});

I needed a regular 10 GB file for testing, so I couldn't use fsutil because it creates sparse files (thanks @ZXX).

@echo off

:: Create file with 2 bytes
echo.>file-big.txt

:: Expand to 1 KB
for /L %%i in (1, 1, 9) do type file-big.txt>>file-big.txt

:: Expand to 1 MB
for /L %%i in (1, 1, 10) do type file-big.txt>>file-big.txt

:: Expand to 1 GB
for /L %%i in (1, 1, 10) do type file-big.txt>>file-big.txt

:: Expand to 4 GB
del file-4gb.txt
for /L %%i in (1, 1, 4) do type file-big.txt>>file-4gb.txt

del file-big.txt

I wanted to create a 10 GB file, but for some reason it only showed up as 4 GB, so I wanted to be safe and stopped at 4 GB. If you really want to be sure your file will be handled properly by the operating system and other applications, stop expanding it at 1 GB.

Responsive Web design (RWD) is a Web design approach aimed at crafting sites to provide an optimal viewing experience

When you design your responsive website you should consider the size of the screen and not the device type. The media queries helps you do that.

If you want to style your site per device, you can use the user agent value, but this is not recommended since you'll have to work hard to maintain your code for new devices, new browsers, browsers versions etc while when using the screen size, all of this does not matter.

You can see some standard resolutions in this link.

BUT, in my opinion, you should first design your website layout, and only then adjust it with media queries to fit possible screen sizes.

Why? As I said before, the screen resolutions variety is big and if you'll design a mobile version that is targeted to 320px your site won't be optimized to 350px screens or 400px screens.

TIPS

1. When designing a responsive page, open it in your desktop browser and change the width of the browser to see how the width of the screen affects your layout and style.
2. Use percentage instead of pixels, it will make your work easier.

Example

I have a table with 5 columns. The data looks good when the screen size is bigger than 600px so I add a breakpoint at 600px and hides 1 less important column when the screen size is smaller. Devices with big screens such as desktops and tablets will display all the data, while mobile phones with small screens will display part of the data.

State of mind

Not directly related to the question but important aspect in responsive design. Responsive design also relate to the fact that the user have a different state of mind when using a mobile phone or a desktop. For example, when you open your bank's site in the evening and check your stocks you want as much data on the screen. When you open the same page in the your lunch break your probably want to see few important details and not all the graphs of last year.

Almost there. In your predicate, you want a relative path, so change

./book[/author/name = 'John'] 

to either

./book[author/name = 'John'] 

or

./book[./author/name = 'John'] 

and you will match your element. Your current predicate goes back to the root of the document to look for an author.

Python has a built in min function to help you with finding the smallest.

However, you need to convert your list items to numbers before you can find the lowest integer( what, isn't that float? )

min(float(i) for i in l)

Git is supposed to understand what files already exist on the server, unless you somehow made a huge difference to your tree and the new changes need to be sent.

To create a new branch with a copy of your current state

git checkout -b new_branch #< create a new local branch with a copy of your code
git push origin new_branch #< pushes to the server

Can you please describe the steps you did to understand what might have made your repository need to send that much to the server.

You could also use CEILING which rounds up to an integer or desired multiple of significance

ie
=CEILING(A1,10)
rounds up to a multiple of 10

12340.0001 will become 12350

I have slightly modified the jangorecki function for the case where we may have a variety of values that cannot be converted to a number. In my function, a template search is performed and if the template is not found, FALSE is returned.! before gperl, it means that we need those vector elements that do not match the template. The rest is similar to the as.num function. Example:

as.num.pattern <- function(x, pattern){
  stopifnot(is.character(x))
  na = !grepl(pattern, x)
  x[na] = -Inf
  x = as.numeric(x)
  x[na] = NA_real_
  x
}

as.num.pattern(c('1', '2', '3.43', 'char1', 'test2', 'other3', '23/40', '23, 54 cm.'))

[1] 1.00 2.00 3.43   NA   NA   NA   NA   NA

If you installed PostgreSQL using the EnterpriseDB installer, then what Kenial suggested is the way to go:

sudo -u postgres pg_ctl -D /Library/PostgreSQL/{version}/data start
sudo -u postgres pg_ctl -D /Library/PostgreSQL/{version}/data stop

Here's a slightly better version of Jared's answer. This one won't end up with deeply nested functions the more you clone. It always calls the original.

Function.prototype.clone = function() {
    var cloneObj = this;
    if(this.__isClone) {
      cloneObj = this.__clonedFrom;
    }

    var temp = function() { return cloneObj.apply(this, arguments); };
    for(var key in this) {
        temp[key] = this[key];
    }

    temp.__isClone = true;
    temp.__clonedFrom = cloneObj;

    return temp;
};

Also, in response to the updated answer given by pico.creator, it is worth noting that the bind() function added in Javascript 1.8.5 has the same problem as Jared's answer - it will keep nesting causing slower and slower functions each time it is used.

Problems with your code and suggestions:

• Again you need to change the preferredSize of the component (here the Graph JPanel), not the size
• Don't set the JFrame's bounds.
• Call pack() on your JFrame after adding components to it and before calling setVisible(true)
• Your foreach loop won't work since the size of your ArrayList is 0 (test it to see that this is correct). Instead use a for loop going from 0 to 10.
• You should not have program logic inside of your paintComponent(...) method but only painting code. So I would make the ArrayList a class variable and fill it inside of the class's constructor.

Which will create a graph that looks like so:

As Darin says, you can read from the input stream - but I'd avoid relying on all the data being available in a single go. If you're using .NET 4 this is simple:

MemoryStream target = new MemoryStream();
model.File.InputStream.CopyTo(target);
byte[] data = target.ToArray();

It's easy enough to write the equivalent of CopyTo in .NET 3.5 if you want. The important part is that you read from HttpPostedFileBase.InputStream.

For efficient purposes you could check whether the stream returned is already a MemoryStream:

byte[] data;
using (Stream inputStream = model.File.InputStream)
{
    MemoryStream memoryStream = inputStream as MemoryStream;
    if (memoryStream == null)
    {
        memoryStream = new MemoryStream();
        inputStream.CopyTo(memoryStream);
    }
    data = memoryStream.ToArray();
}

I'm sorry to necro an old post - but I found a better way of doing this

What I believe this poster wanted was :

<label for="mydropdown" datalabel="mydropdown">Country:</label>    
<select name="mydropdown">
    <option value="United States">United States</option>
    <option value="Canada">Canada</option>
    <option value="Mexico">Mexico</option>
    <option value="Other">Not Listed</option>
</select>

I found this information in another post while searching for this same answer - Thanks

As Bokan has mentioned, you can up the memory if available, and he is right on how counter productive setting TTL to 0 is.

NotE: This is how I fixed this error for my particular problem. Its a generic issue that can be caused by allot of things so only follow the below if you get the error and you think its caused by duplicate PHP files being loaded into APC.

The issue I was having was when I released a new version of my PHP application. Ie replaced all my .php files with new ones APC would load both versions into cache.

Because I didnt have enough memory for two versions of the php files APC would run out of memory.

There is a option called apc.stat to tell APC to check if a particular file has changed and if so replace it, this is typically ok for development because you are constantly making changes however on production its usually turned off as it was with in my case - http://www.php.net/manual/en/apc.configuration.php#ini.apc.stat

Turning apc.stat on would fix this issue if you are ok with the performance hit.

The solution I came up with for my problem is check if the the project version has changed and if so empty the cache and reload the page.

define('PROJECT_VERSION', '0.28'); 

if(apc_exists('MY_APP_VERSION') ){

    if(apc_fetch('MY_APP_VERSION') != PROJECT_VERSION){
        apc_clear_cache();
        apc_store ('MY_APP_VERSION', PROJECT_VERSION);
        header('Location: ' . 'http'.(empty($_SERVER['HTTPS'])?'':'s').'://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI']);
        exit;  
    }

}else{
    apc_store ('MY_APP_VERSION', PROJECT_VERSION);
}

when you say 'appendchild' you actually move your child from one parent to another. you have to create a node for each cell.

you can download USBview and get all the information you need. Along with the list of devices it will also show you the configuration of each device.

Firstly, you need to change this line:

element.setAttribute("onclick", alert("blabla"));

To something like this:

element.setAttribute("onclick", function() { alert("blabla"); });

Secondly, you may have browser compatibility issues when attaching events that way. You might need to use .attachEvent / .addEvent, depending on which browser. I haven't tried manually setting event handlers for a while, but I remember firefox and IE treating them differently.

Element objects have no .getroot() method. Drop that call, and the .tostring() call works:

xmlstr = ElementTree.tostring(et, encoding='utf8', method='xml')

You only need to use .getroot() if you have an ElementTree instance.

Other notes:

• This produces a bytestring, which in Python 3 is the bytes type.
  If you must have a str object, you have two options:

  1. Decode the resulting bytes value, from UTF-8: xmlstr.decode("utf8")

  2. Use encoding='unicode'; this avoids an encode / decode cycle:

     xmlstr = ElementTree.tostring(et, encoding='unicode', method='xml')
     

• If you wanted the UTF-8 encoded bytestring value or are using Python 2, take into account that ElementTree doesn't properly detect utf8 as the standard XML encoding, so it'll add a <?xml version='1.0' encoding='utf8'?> declaration. Use utf-8 or UTF-8 (with a dash) if you want to prevent this. When using encoding="unicode" no declaration header is added.

Which Mac version are you using? try these paths

 /System/Library/Frameworks/JavaVM.framework/ OR
 /usr/libexec/java_home

This link might help - How To Set $JAVA_HOME Environment Variable On Mac OS X

The conversion of your code to Swift 4 can also be done this way:

let str = "Hello, playground"
let index = str.index(of: ",")!
let substr = str.prefix(upTo: index)

You can use the code below to have a new string:

let newString = String(str.prefix(upTo: index))

        link: function (scope, element, attrs) {_x000D_
            _x000D_
            if (scope.$first) {_x000D_
                $blockUI.blockElement($(element).parent());_x000D_
            }_x000D_
            if (scope.$last) {_x000D_
                $blockUI.unblockElement($(element).parent());_x000D_
            }_x000D_
        }_x000D_
    };_x000D_
})

I came across the same situation in my ASP.NET website. I deleted the published files, restarted VS, cleaned and rebuild the project again. After the next publish, the error was gone...

I think you should be able to select a disabled button using the following:

button[disabled=disabled], button:disabled {
    // your css rules
}

Definitely should use a dict using the "group" + str(i) key as described in the accepted solution but I wanted to share a solution using exec. Its a way to parse strings into commands & execute them dynamically. It would allow to create these scalar variable names as per your requirement instead of using a dict. This might help in regards what not to do, and just because you can doesn't mean you should. Its a good solution only if using scalar variables is a hard requirement:

l = locals()
for i in xrange(3):
    exec("group" + str(i) + "= self.getGroup(selected, header + i)")

Another example where this could work using a Django model example. The exec alternative solution is commented out and the better way of handling such a case using the dict attribute makes more sense:

Class A(models.Model):

    ....

    def __getitem__(self, item):  # a.__getitem__('id')
        #exec("attrb = self." + item)
        #return attrb
        return self.__dict__[item]

It might make more sense to extend from a dictionary in the first place to get setattr and getattr functions.

A situation which involves parsing, for example generating & executing python commands dynamically, exec is what you want :) More on exec here.

if you want to do screen capture from Java code in Android app AFAIK you must have Root provileges.

I had this error too , and finally this codes worked for me in dot net core 3.1

first install svcutil in command prompt : dotnet tool install --global dotnet-svcutil

Then close command prompt and open it again.

Then create the Reference.cs in command prompt :

dotnet-svcutil http://YourService.com/SayHello.svc

(It needs an enter key and UserName and Password)

Add a folder named Connected Services to project root.

Copy Reference.cs file to Connected Services folder.

Add these 4 lines to Reference.cs after lines where creating BasicHttpBinding and setting MaxBufferSize :

result.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly;
result.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic;
result.Security.Transport.ProxyCredentialType = HttpProxyCredentialType.None;
result.Security.Message.ClientCredentialType = BasicHttpMessageCredentialType.UserName;

Use this service in your Controller :

public async Task<string> Get()
    {
        try
        {
            var client = new EstelamClient();
            client.ClientCredentials.UserName.UserName = "YourUserName";
            client.ClientCredentials.UserName.Password = "YourPassword";
            var res = await client.EmployeeCheckAsync("service parameters");
            return res.ToString();
        }
        catch (Exception ex)
        {
            return ex.Message + " ************ stack : " + ex.StackTrace;
        }

    }

Do not forget install these packages in .cshtml :

<PackageReference Include="System.ServiceModel.Duplex" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.Http" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.NetTcp" Version="4.6.*" />
<PackageReference Include="System.ServiceModel.Security" Version="4.6.*" />

I had a similar problem.

When I entered

<activity android:name="MyActivity" android:screenOrientation="landscape"></activity>

In the manifest file this caused that activity to display in landscape. However when I returned to previous activities they displayed in lanscape even though they were set to portrait. However by adding

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

immediately after the OnCreate section of the target activity resolved the problem. So I now use both methods.

The way how I'm handling the Divider view and also Divider Insets is by adding a RecyclerView extension.

1.

Add a new extension file by naming View or RecyclerView:

RecyclerViewExtension.kt

and add the setDivider extension method inside the RecyclerViewExtension.kt file.

/*
* RecyclerViewExtension.kt
* */
import androidx.annotation.DrawableRes
import androidx.core.content.ContextCompat
import androidx.recyclerview.widget.DividerItemDecoration
import androidx.recyclerview.widget.RecyclerView


fun RecyclerView.setDivider(@DrawableRes drawableRes: Int) {
    val divider = DividerItemDecoration(
        this.context,
        DividerItemDecoration.VERTICAL
    )
    val drawable = ContextCompat.getDrawable(
        this.context,
        drawableRes
    )
    drawable?.let {
        divider.setDrawable(it)
        addItemDecoration(divider)
    }
}

2.

Create a Drawable resource file inside of drawable package like recycler_view_divider.xml:

<inset xmlns:android="http://schemas.android.com/apk/res/android"
    android:insetLeft="10dp"
    android:insetRight="10dp">

    <shape>
        <size android:height="0.5dp" />
        <solid android:color="@android:color/darker_gray" />
    </shape>

</inset>

where you can specify the left and right margin on android:insetLeft and android:insetRight.

3.

On your Activity or Fragment where the RecyclerView is initialized, you can set the custom drawable by calling:

recyclerView.setDivider(R.drawable.recycler_view_divider)

4.

Cheers

This should work. You need to put in two slashes

str = str.replaceAll("(\\r\\n|\\n)", "<br />");

In this Reference, there is an example which shows

private final String REGEX = "\\d"; // a single digit

I have used two slashes in many of my projects and it seems to work fine!

In some cases, Reflection doesn't work properly.

You could use dictionaries, if all item types are the same. For instance, if your items are strings :

Dictionary<string, string> response = JsonConvert.DeserializeObject<Dictionary<string, string>>(item);

Or ints:

Dictionary<string, int> response = JsonConvert.DeserializeObject<Dictionary<string, int>>(item);

    <style>
    .Button
    {
        margin:5px;
    }
    </style>

 <asp:Button ID="Button1" runat="server" Text="Button" CssClass="Button" />
 <asp:Button ID="Button2" runat="server" Text="Button" CssClass="Button"/>

Open below file C:\xampp\htdocs\project\common\config\params-local.php

Before your code:

<?php

return [


];

after your code:

<?php
yii::setAlias('@path1', 'localhost/foodbam/backend/web');

return [


];

Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.

foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){                      
            System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
            foreach(Type type in asm.GetTypes()){   
                //PROPERTIES
                foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
                    if (property.CanRead){
                        Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);       
                    }
                }
                //METHODS
                var methods = type.GetMethods();
                foreach (System.Reflection.MethodInfo method in methods){               
                    Response.Write("<br><b>" + an.ToString() + "."  + type.ToString() + "." + method.Name  + "</b>");   
                    foreach (System.Reflection.ParameterInfo param in method.GetParameters())
                    {
                        Response.Write("<br><i>Param=" + param.Name.ToString());
                        Response.Write("<br>  Type=" + param.ParameterType.ToString());
                        Response.Write("<br>  Position=" + param.Position.ToString());
                        Response.Write("<br>  Optional=" + param.IsOptional.ToString() + "</i>");
                    }
                }
            }
        }

See https://developer.mozilla.org/en/DOM/document.cookie for more documentation:

     if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/.test(sKey)) { return; }  
     var sExpires = "";  
     if (vEnd) {  
       switch (typeof vEnd) {  
         case "number": sExpires = "; max-age=" + vEnd; break;  
         case "string": sExpires = "; expires=" + vEnd; break;  
         case "object": if (vEnd.hasOwnProperty("toGMTString")) { sExpires = "; expires=" + vEnd.toGMTString(); } break;

Try using:

git checkout branchName -- fileName

Ex:

git checkout master -- index.php

I'll show you how to change the image src, so that when you click an image it rotates through all the images that are in your HTML (in your d1 id and c1 class specifically)... whether you have 2 or more images in your HTML.

I'll also show you how to clean up the page after the document is ready, so that only one image is displayed initially.

The full code

$(function() {

    var $images = $("#d1 > .c1 > a").clone();  

    var $length = $images.length;
    var $imgShow = 0;

    $("#d1 > .c1").html( $("#d1 > .c1 > a:first") );  

    $("#d1 > .c1 > a").click(function(event) { 

        $(this).children().attr("src", 
                        $("img", $images).eq(++$imgShow % $length).attr("src") );
        event.preventDefault();

    });
});

The breakdown

1. Create a copy of the links containing the images (note: you could also make use of the href attribute of the links for added functionality... for example display the working link below each image):

       var $images = $("#d1 > .c1 > a").clone();  ;
   

2. Check how many images were in the HTML and create a variable to track which image is being shown:

   var $length = $images.length;
   var $imgShow = 0;
   

3. Modify the document's HTML so that only the first image is being shown. Delete all the other images.

   $("#d1 > .c1").html( $("#d1 > .c1 > a:first") ); 
   

4. Bind a function to handle when the image link is clicked.

       $("#d1 > .c1 > a").click(function(event) { 
           $(this).children().attr("src", $("img", $images).eq(++$imgShow % $length).attr("src") );
           event.preventDefault();
       });
   

   The heart of the above code is using ++$imgShow % $length to cycle through the jQuery object containing the images. ++$imgShow % $length first increases our counter by one, then it mods that number with how many images there are. This will keep the resultant index cycling from 0 to length-1, which are the indices of the $images object. This means this code will work with 2, 3, 5, 10, or 100 images... cycling through each image in order and restarting at the first image when the last image is reached.

   Additionally, .attr() is used to get and set the "src" attribute of the images. To pick elements from among the $images object, I set $images as the jQuery context using the form $(selector, context). Then I use .eq() to pick just the element with the specific index I'm interested in.

jsFiddle example with 3 images

You can also store the srcs in an array.

And here's how to incorporate the hrefs from the anchor tags around the images:

Lets assume you have data in D and E cells.. Here is an easiest ratio displaying fn by my frnd 'Karthik'

=ROUND(D7/E7, 2) &":" & (E7/E7)

Swift 2.0 Works fine for me!

 func collectionView(collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, insetForSectionAtIndex section: Int) -> UIEdgeInsets {
        let edgeInsets = (screenWight - (CGFloat(elements.count) * 50) - (CGFloat(elements.count) * 10)) / 2
        return UIEdgeInsetsMake(0, edgeInsets, 0, 0);
    }

Where: screenWight: basically its my collection's width (full screen width) - I made constants: let screenWight:CGFloat = UIScreen.mainScreen().bounds.width because self.view.bounds shows every-time 600 - coz of SizeClasses elements - array of cells 50 - my manual cell width 10 - my distance between cells

int is a primitive, null is not a value that it can take on. You could change the method return type to return java.lang.Integer and then you can return null, and existing code that returns int will get autoboxed.

Nulls are assigned only to reference types, it means the reference doesn't point to anything. Primitives are not reference types, they are values, so they are never set to null.

Using the object wrapper java.lang.Integer as the return value means you are passing back an Object and the object reference can be null.

if you want to connect with oracle database

1. open sql prompt
2. connect with sysdba for XE- conn / as sysdba for IE- conn sys as sysdba
3. then start up database by below command startup;

once it get start means you can access oracle database now. if you want connect another user you can write conn username/password e.g. conn scott/tiger; it will show connected........

In PostgreSQL, to get the average of multiple (2 to 8) columns in one row just define a set of seven functions called average(). Will produce the average of the non-null columns.

And then just

Why not use the <textarea> tag?

?<textarea id="txtArea" rows="10" cols="70"></textarea>

You can try and define the following macro:

#define for_range(_type, _param, _A1, _B1) for (bool _ok = true; _ok;)\
for (_type _start = _A1, _finish = _B1; _ok;)\
    for (int _step = 2*(((int)_finish)>(int)_start)-1;_ok;)\
         for (_type _param = _start; _ok ; \
 (_param != _finish ? \
           _param = static_cast<_type>(((int)_param)+_step) : _ok = false))

Now you can use it:

enum Count { zero, one, two, three }; 

    for_range (Count, c, zero, three)
    {
        cout << "forward: " << c << endl;
    }

It can be used to iterate backwards and forwards through unsigned, integers, enums and chars:

for_range (unsigned, i, 10,0)
{
    cout << "backwards i: " << i << endl;
}


for_range (char, c, 'z','a')
{
    cout << c << endl;
}

Despite its awkward definition it is optimized very well. I looked at disassembler in VC++. The code is extremely efficient. Don't be put off but the three for statements: the compiler will produce only one loop after optimization! You can even define enclosed loops:

unsigned p[4][5];

for_range (Count, i, zero,three)
    for_range(unsigned int, j, 4, 0)
    {   
        p[i][j] = static_cast<unsigned>(i)+j;
    }

You obviously cannot iterate through enumerated types with gaps.

I know this topic is old but I think I can contribute. You can trigger the default behavior of an event on a specific element any time in your handler function if you already know that behavior. For example, when you trigger the click event on the reset button, you actually call the reset function on the closest form as the default behavior. In your handler function, after using the preventDefault function, you can recall the default behavior by calling the reset function on the closest form anywhere in your handler code.

i tried all the solution above but none of them works for me. finaly i solved it myself, and find actually it's quite easy. there are two points you need to be careful.

parameters.setPreviewSize(cameraResolution.x, cameraResolution.y);

this previewSize must be one of the camera supported resolution, which can be get as below:

List<Camera.Size> rawSupportedSizes = parameters.getSupportedPreviewSizes(); 

usually one of the rawSupportedSize equals to the device resolution.

Second, place your SurfaceView in a FrameLayout and set the surface layout height and width in surfaceChanged method as above

FrameLayout.LayoutParams layoutParams = (FrameLayout.LayoutParams) surfaceView.getLayoutParams();
layoutParams.height = cameraResolution.x;
layoutParams.width = cameraResolution.y;

Ok, things done, hope this could help you.

You need to verify the properties of the files.

To assign the required property, use:

$ chmod 600 ~/.ssh/sshKey
$ chmod 644 ~/.ssh/sshKey.pub

imageView.layer.cornerRadius = imageView.frame.height/2
imageView.clipToBounds = true

As Blazemonger said, #parent, .panel and .collapse have to be direct descendants. However, if You can't change Your html, You can do workaround using bootstrap events and methods with the following code:

$('#your-parent .collapse').on('show.bs.collapse', function (e) {
    var actives = $('#your-parent').find('.in, .collapsing');
    actives.each( function (index, element) {
        $(element).collapse('hide');
    })
})

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

c.take(10)

and Spark newer version will show table nicely.

I would suggest the following simple approach for conversion:

from datetime import datetime, timedelta
s = "20120213"
# you could also import date instead of datetime and use that.
date = datetime(year=int(s[0:4]), month=int(s[4:6]), day=int(s[6:8]))

For adding/subtracting an arbitary amount of days (seconds work too btw.), you could do the following:

date += timedelta(days=10)
date -= timedelta(days=5)

And convert back using:

s = date.strftime("%Y%m%d")

To convert the integer to a string safely, use:

s = "{0:-08d}".format(i)

This ensures that your string is eight charecters long and left-padded with zeroes, even if the year is smaller than 1000 (negative years could become funny though).

Further reference: datetime objects, timedelta objects

For those who just need to join one level below at the top.

Being clearer, how transform this:

Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [id] => 001
                    )
                [1] => Array
                    (
                        [id] => 005
                    )
            )
        [1] => Array
            (
                [0] => Array
                    (
                        [id] => 007
                    )
                [1] => Array
                    (
                        [id] => 009
                    )
            )
    )

On this:

Array
    (
        [0] => Array
            (
                [0] => Array
                    (
                        [id] => 001
                    )
                [1] => Array
                    (
                        [id] => 005
                    )
                [2] => Array
                    (
                        [id] => 007
                    )
                [3] => Array
                    (
                        [id] => 009
                    )
            )
    )

The (simple) code:

foreach ($multi_array as $key => $reduced_array) {
    foreach ($reduced_array as $key => $value) {
        $new_array[] = $value;
    }
}

With so many functions available, sometimes we forget that we can do something with a simple code ...

    function ArrayToObject( arr ) {
    var obj = {};
    for (var i = 0; i < arr.length; ++i){
        var name = arr[i].name;
        var value = arr[i].value;
        obj[name] = arr[i].value;
    }
    return obj;
    }

      var form_data = $('#my_form').serializeArray();
            form_data = ArrayToObject( form_data );
            form_data.action = event.target.id;
            form_data.target = event.target.dataset.event;
            console.log( form_data );
            $.post("/api/v1/control/", form_data, function( response ){
                console.log(response);
            }).done(function( response ) {
                $('#message_box').html('SUCCESS');
            })
            .fail(function(  ) { $('#message_box').html('FAIL'); })
            .always(function(  ) { /*$('#message_box').html('SUCCESS');*/ });

If you come from Java/C# background I guess your best bet would be to use Eclipse with Pydev. This gives you a fully functional IDE with debugger built in. I use it with django as well.

grep 2.5.3 introduced the --exclude-dir parameter which will work the way you want.

grep -rI --exclude-dir=\.svn PATTERN .

You can also set an environment variable: GREP_OPTIONS="--exclude-dir=\.svn"

I'll second Andy's vote for ack though, it's the best.

Going by this article http://en.wikipedia.org/wiki/Criticism_of_Java#Large_arrays:

Java has been criticized for not supporting arrays of more than 2³¹-1 (about 2.1 billion) elements. This is a limitation of the language; the Java Language Specification, Section 10.4, states that:

Arrays must be indexed by int values... An attempt to access an array component with a long index value results in a compile-time error.

Supporting large arrays would also require changes to the JVM. This limitation manifests itself in areas such as collections being limited to 2 billion elements and the inability to memory map files larger than 2 GiB. Java also lacks true multidimensional arrays (contiguously allocated single blocks of memory accessed by a single indirection), which limits performance for scientific and technical computing.

There is the "Compare" plugin. You can install it via Plugins > Plugin Manager.

Alternatively you can install a specialized file compare software like WinMerge.

You can also try adding the Motumedia PPA to your apt sources and update your ffmpeg packages.

You can use TrimEnd. It's efficient as well and looks clean.

"Name,".TrimEnd(',');

You can use the OpenSSL Command line tool. The following commands should do the trick

openssl pkcs12 -in client_ssl.pfx -out client_ssl.pem -clcerts

openssl pkcs12 -in client_ssl.pfx -out root.pem -cacerts

If you want your file to be password protected etc, then there are additional options.

You can read the entire documentation here.

Surprised that no one mentioned this yet, but you can simply template on anything 2D supporting [][] semantics.

template <typename TwoD>
void myFunction(TwoD& myArray){
     myArray[x][y] = 5;
     etc...
}

// call with
double anArray[10][10];
myFunction(anArray);

It works with any 2D "array-like" datastructure, such as std::vector<std::vector<T>>, or a user defined type to maximize code reuse.

The correct path to the sdcard is

/mnt/sdcard/

but, as answered before, you shouldn't hardcode it. If you are on Android 2.1 or after, use

getExternalFilesDir(String type) 

Otherwise:

Environment.getExternalStorageDirectory()

Read carefully https://developer.android.com/guide/topics/data/data-storage.html#filesExternal

Also, you'll need to use this method or something similar

boolean mExternalStorageAvailable = false;
boolean mExternalStorageWriteable = false;
String state = Environment.getExternalStorageState();

if (Environment.MEDIA_MOUNTED.equals(state)) {
    // We can read and write the media
    mExternalStorageAvailable = mExternalStorageWriteable = true;
} else if (Environment.MEDIA_MOUNTED_READ_ONLY.equals(state)) {
    // We can only read the media
    mExternalStorageAvailable = true;
    mExternalStorageWriteable = false;
} else {
    // Something else is wrong. It may be one of many other states, but all we need
    //  to know is we can neither read nor write
    mExternalStorageAvailable = mExternalStorageWriteable = false;
}

then check if you can access the sdcard. As said, read the official documentation.

Another option, maybe you need to use mkdirs instead of mkdir

file.mkdirs()

Creates the directory named by the trailing filename of this file, including the complete directory path required to create this directory.

TCP / HTTP Listening On Ports: How Can Many Users Share the Same Port

So, what happens when a server listen for incoming connections on a TCP port? For example, let's say you have a web-server on port 80. Let's assume that your computer has the public IP address of 24.14.181.229 and the person that tries to connect to you has IP address 10.1.2.3. This person can connect to you by opening a TCP socket to 24.14.181.229:80. Simple enough.

Intuitively (and wrongly), most people assume that it looks something like this:

    Local Computer    | Remote Computer
    --------------------------------
    <local_ip>:80     | <foreign_ip>:80

    ^^ not actually what happens, but this is the conceptual model a lot of people have in mind.

This is intuitive, because from the standpoint of the client, he has an IP address, and connects to a server at IP:PORT. Since the client connects to port 80, then his port must be 80 too? This is a sensible thing to think, but actually not what happens. If that were to be correct, we could only serve one user per foreign IP address. Once a remote computer connects, then he would hog the port 80 to port 80 connection, and no one else could connect.

Three things must be understood:

1.) On a server, a process is listening on a port. Once it gets a connection, it hands it off to another thread. The communication never hogs the listening port.

2.) Connections are uniquely identified by the OS by the following 5-tuple: (local-IP, local-port, remote-IP, remote-port, protocol). If any element in the tuple is different, then this is a completely independent connection.

3.) When a client connects to a server, it picks a random, unused high-order source port. This way, a single client can have up to ~64k connections to the server for the same destination port.

So, this is really what gets created when a client connects to a server:

    Local Computer   | Remote Computer           | Role
    -----------------------------------------------------------
    0.0.0.0:80       | <none>                    | LISTENING
    127.0.0.1:80     | 10.1.2.3:<random_port>    | ESTABLISHED

Looking at What Actually Happens

First, let's use netstat to see what is happening on this computer. We will use port 500 instead of 80 (because a whole bunch of stuff is happening on port 80 as it is a common port, but functionally it does not make a difference).

    netstat -atnp | grep -i ":500 "

As expected, the output is blank. Now let's start a web server:

    sudo python3 -m http.server 500

Now, here is the output of running netstat again:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      - 

So now there is one process that is actively listening (State: LISTEN) on port 500. The local address is 0.0.0.0, which is code for "listening for all ip addresses". An easy mistake to make is to only listen on port 127.0.0.1, which will only accept connections from the current computer. So this is not a connection, this just means that a process requested to bind() to port IP, and that process is responsible for handling all connections to that port. This hints to the limitation that there can only be one process per computer listening on a port (there are ways to get around that using multiplexing, but this is a much more complicated topic). If a web-server is listening on port 80, it cannot share that port with other web-servers.

So now, let's connect a user to our machine:

    quicknet -m tcp -t localhost:500 -p Test payload.

This is a simple script (https://github.com/grokit/quickweb) that opens a TCP socket, sends the payload ("Test payload." in this case), waits a few seconds and disconnects. Doing netstat again while this is happening displays the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:54240      ESTABLISHED -

If you connect with another client and do netstat again, you will see the following:

    Proto Recv-Q Send-Q Local Address           Foreign Address         State  
    tcp        0      0 0.0.0.0:500             0.0.0.0:*               LISTEN      -
    tcp        0      0 192.168.1.10:500        192.168.1.13:26813      ESTABLISHED -

... that is, the client used another random port for the connection. So there is never confusion between the IP addresses.

I'll add this cause of the error as well in hopes it helps some future internet traveler. :)

GDI+ limits the maximum height of an image to 65500

We do some basic image resizing, but in resizing we try to maintain aspect ratio. We have a QA guy who's a little too good at this job; he decided to test this with a ONE pixel wide photo that was 480 pixels tall. When the image was scaled to meet our dimensions, the height was north of 68,000 pixels and our app exploded with A generic error occurred in GDI+.

You can verify this yourself with test:

  int width = 480;
  var height = UInt16.MaxValue - 36; //succeeds at 65499, 65500
  try
  {
    while(true)
    {
      var image = new Bitmap(width, height);
      using(MemoryStream ms = new MemoryStream())
      {
        //error will throw from here
        image.Save(ms, ImageFormat.Jpeg);
      }
      height += 1;
    }
  }
  catch(Exception ex)
  {
    //explodes at 65501 with "A generic error occurred in GDI+."
  }

It's too bad there's not a friendly .net ArgumentException thrown in the constructor of Bitmap.

I've added some code to my project, so it's more convenient.

HtmlExtensions.cs:

namespace System.Web.Mvc.Html
{
    public static class HtmlExtensions
    {
        public static MvcForm BeginForm(this HtmlHelper htmlHelper, string formId)
        {
            return htmlHelper.BeginForm(null, null, FormMethod.Post, new { id = formId });
        }

        public static MvcForm BeginForm(this HtmlHelper htmlHelper, string formId, FormMethod method)
        {
            return htmlHelper.BeginForm(null, null, method, new { id = formId });
        }
    }
}

MySignupForm.cshtml:

@using (Html.BeginForm("signupform")) 
{
    @* Some fields *@
}

Check with following css. Demo

.circle { 
   width: 140px;
   height: 140px;
   background: red; 
   -moz-border-radius: 70px; 
   -webkit-border-radius: 70px; 
   border-radius: 70px;
}

Following solution worked for me on chrome 65 (ref) -

Create an OpenSSL config file (example: req.cnf)

[req]
distinguished_name = req_distinguished_name
x509_extensions = v3_req
prompt = no
[req_distinguished_name]
C = US
ST = VA
L = SomeCity
O = MyCompany
OU = MyDivision
CN = www.company.com
[v3_req]
keyUsage = critical, digitalSignature, keyAgreement
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
DNS.1 = www.company.com
DNS.2 = company.com
DNS.3 = company.net

Create the certificate referencing this config file

openssl req -x509 -nodes -days 730 -newkey rsa:2048 \
 -keyout cert.key -out cert.pem -config req.cnf -sha256

export CFLAGS=-m32

Lazy exceptions occur when you fetch an object typically containing a collection which is lazily loaded, and try to access that collection.

You can avoid this problem by

• accessing the lazy collection within a transaction.
• Initalizing the collection using Hibernate.initialize(obj);
• Fetch the collection in another transaction
• Use Fetch profiles to select lazy/non-lazy fetching runtime
• Set fetch to non-lazy (which is generally not recommended)

Further I would recommend looking at the related links to your right where this question has been answered many times before. Also see Hibernate lazy-load application design.

Here is solution:

<?php
$students['e1003']['birthplace'] = ("Mandaluyong <br>");
$students['ter1003']['birthplace'] = ("San Juan <br>");
$students['fgg1003']['birthplace'] = ("Quezon City <br>");
$students['bdf1003']['birthplace'] = ("Manila <br>");

$key = array_search('Delata Jona', array_column($students, 'name'));
echo $key;  

?>

This can be done using HTML5, but will only work in browsers that support it. Here's an example.

Bear in mind you'll need an alternative method for browsers that don't support this. I've had a lot of success with this plugin, which takes a lot of the work out of your hands.

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

How about:

(sleep 5; echo "Hello World") &

this works in ubuntu 18 and above (not tested in previous versions):

sudo apt install python3-virtualenv

AFAIK it is GRADLE_HOME not GRADLE_USER_HOME (see gradle installation http://www.gradle.org/installation).

On the other hand I played a bit with Gradle support in Idea 13 Cardea and I think the gradle home is not automatically discover by Idea. If so you can file a issue in youtrack.

Also, if you use gradle 1.6+ you can use the Graldle support for setting the build and wrapper. I think idea automatically discover the wrapper based gradle project.

$ gradle setupBuild --type java-library

$ gradle wrapper

Note: Supported library types: basic, maven, java

For even more robustness:

function getIframeWindow(iframe_object) {
  var doc;

  if (iframe_object.contentWindow) {
    return iframe_object.contentWindow;
  }

  if (iframe_object.window) {
    return iframe_object.window;
  } 

  if (!doc && iframe_object.contentDocument) {
    doc = iframe_object.contentDocument;
  } 

  if (!doc && iframe_object.document) {
    doc = iframe_object.document;
  }

  if (doc && doc.defaultView) {
   return doc.defaultView;
  }

  if (doc && doc.parentWindow) {
    return doc.parentWindow;
  }

  return undefined;
}

and

...
var el = document.getElementById('targetFrame');

var frame_win = getIframeWindow(el);

if (frame_win) {
  frame_win.reset();
  ...
}
...

I'll post this comment as answer, as I'm confident enough that what I asked is not possible.

I) Couple of similar questions trying to do the same, without success:

• Pivot Calculated formula: SUM(Field1)/AVG(Field2)
• Excel Pivot Table Calculated Field

II) This article: Excel Pivot Table Calculated Field for example lists many restrictions of Calculated Field:

• For calculated fields, the individual amounts in the other fields are summed, and then the calculation is performed on the total amount.
• Calculated field formulas cannot refer to the pivot table totals or subtotals
• Calculated field formulas cannot refer to worksheet cells by address or by name.
• Sum is the only function available for a calculated field.
• Calculated fields are not available in an OLAP-based pivot table.

III) There is tiny limited possibility to use AVERAGE() and similar function for a range of cells, but that applies only if Pivot table doesn't have grouped cells, which allows listing the cells as items in new group (right to "Fileds" listbox in above screenshot) and then user can calculate AVERAGE(), referencing explicitly every item (cell), from Items listbox, as argument. Maybe it's better explained here: Calculate values in a PivotTable report
For my Pivot table it wasn't applicable because my range wasn't small enough, this option to be sane choice.

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

If you're using Kotlin, API 14+, and just wish to show uninstall dialog for your app:

startActivity(Intent(Intent.ACTION_UNINSTALL_PACKAGE).apply {
    data = Uri.parse("package:$packageName")
})

You can change packageName to any other package name if you want to prompt the user to uninstall another app on the device

One way around this problem is to use stored procedures with an output parameter.

exec sp_mysprocname @returnvalue output, @firstparam = 1, @secondparam=2

values you do not pass in default to the defaults set in the stored procedure itself. And you can get the results from your output variable.

i find this method from ClickHouse Operator Build From Sources and it helps and save my life!

docker save altinity/clickhouse-operator | (eval $(minikube docker-env) && 
docker load)

Try a versiontracker search instead. SqliteManager from SQLabs ($49, Mac & Windows) is the one I prefer, but I haven't really evaluated the other alternatives.

Try this solution:

for m in ["a", "á", "à", "ã", "â"]:
    try:
        somelist.remove(m)
    except:
        pass

Just for your information. and and or operators are also using to return values. It is useful when you need to assign value to variable but you have some pre-requirements

operator or returns first not null value

#init values
a,b,c,d = (1,2,3,None)

print(d or a or b or c)
#output value of a - 1

print(b or a or c or d)
#output value of b - 2

Operator and returns last value in the sequence if any of the members don't have None value or if they have at least one None value we get None

print(a and d and b and c)
#output: None

print(a or b or c)
#output value of c - 3

You may want to use:

SELECT Name, 'Unpaid' AS Status FROM table;

The SELECT clause syntax, as defined in MSDN: SELECT Clause (Transact-SQL), is as follows:

SELECT [ ALL | DISTINCT ]
[ TOP ( expression ) [ PERCENT ] [ WITH TIES ] ] 
<select_list> 

Where the expression can be a constant, function, any combination of column names, constants, and functions connected by an operator or operators, or a subquery.

Try the arithmetic-expression version of for:

max=10
for (( i=2; i <= $max; ++i ))
do
    echo "$i"
done

This is available in most versions of bash, and should be Bourne shell (sh) compatible also.

You can create your own custom config section in the app.config file. There are quite a few tutorials around to get you started. Ultimately, you could have something like this:

<configSections>
    <section name="backupDirectories" type="TestReadMultipler2343.BackupDirectoriesSection, TestReadMultipler2343" />
  </configSections>

<backupDirectories>
   <directory location="C:\test1" />
   <directory location="C:\test2" />
   <directory location="C:\test3" />
</backupDirectories>

To complement Richard's answer, this is the C# you could use with his sample configuration:

using System.Collections.Generic;
using System.Configuration;
using System.Xml;

namespace TestReadMultipler2343
{
    public class BackupDirectoriesSection : IConfigurationSectionHandler
    {
        public object Create(object parent, object configContext, XmlNode section)
        {
            List<directory> myConfigObject = new List<directory>();

            foreach (XmlNode childNode in section.ChildNodes)
            {
                foreach (XmlAttribute attrib in childNode.Attributes)
                {
                    myConfigObject.Add(new directory() { location = attrib.Value });
                }
            }
            return myConfigObject;
        }
    }

    public class directory
    {
        public string location { get; set; }
    }
}

Then you can access the backupDirectories configuration section as follows:

List<directory> dirs = ConfigurationManager.GetSection("backupDirectories") as List<directory>;

With dataclasses, a feature added in Python 3.7, there is now yet another (quite convenient) way to achieve setting default values on class instances. The decorator dataclass will automatically generate a few methods on your class, such as the constructor. As the documentation linked above notes, "[t]he member variables to use in these generated methods are defined using PEP 526 type annotations".

Considering OP's example, we could implement it like this:

from dataclasses import dataclass

@dataclass
class Foo:
    num: int = 0

When constructing an object of this class's type we could optionally overwrite the value.

print('Default val: {}'.format(Foo()))
# Default val: Foo(num=0)
print('Custom val: {}'.format(Foo(num=5)))
# Custom val: Foo(num=5)

this will do it with just javascript - you can also put the function in a .js file and call it with onclick

//button
<div onclick="
   document.forms['name_of_the_form']['name_of_the_input'].value += 'text you want to add to it'"
>button</div>

I created these functions based on Joey Guerra's suggestion, thank you for that. I'm elaborating a little bit, perhaps someone can use it. The first function checkDefaults() is called when an input changes, the second is called when the form is submitted using jQuery.post. div.updatesubmit is my submit button, and class 'needsupdate' is an indicator that an update is made but not yet submitted.

function checkDefaults() {
    var changed = false;
        jQuery('input').each(function(){
            if(this.defaultValue != this.value) {
                changed = true;
            }
        });
        if(changed === true) {
            jQuery('div.updatesubmit').addClass("needsupdate");
        } else {
            jQuery('div.updatesubmit').removeClass("needsupdate");
        }
}

function renewDefaults() {
        jQuery('input').each(function(){
            this.defaultValue = this.value;
        });
        jQuery('div.updatesubmit').removeClass("needsupdate");
}

This started happening to me when my database size grew and I was doing a lot of transactions on it.

Truth is there is probably some way to optimize either your queries or your DB but try these 2 queries for a work around fix.

Run this:

SET GLOBAL innodb_lock_wait_timeout = 5000; 

And then this:

SET innodb_lock_wait_timeout = 5000; 

Date todayDate = new Date();
todayDate.getDay();
todayDate.getHours();
todayDate.getMinutes();
todayDate.getMonth();
todayDate.getTime();

You cannot pass custom parameters in addTarget:.One alternative is set the tag property of button and do work based on the tag.

button.tag = 5
button.addTarget(self, action: "buttonClicked:", 
    forControlEvents: UIControlEvents.TouchUpInside)

Or for Swift 2.2 and greater:

button.tag = 5
button.addTarget(self,action:#selector(buttonClicked),
    forControlEvents:.TouchUpInside)

Now do logic based on tag property

@objc func buttonClicked(sender:UIButton)
{
    if(sender.tag == 5){

        var abc = "argOne" //Do something for tag 5
    }
    print("hello")
}

The solution is to change the DropDownStyle property to DropDownList. It will help.

A way to replace it with a java 8 stream:

public static void main(String[] args) throws IOException
{
    String test = "ab19198zxncvl1308j10923.";
    StringBuilder result = new StringBuilder();

    test.chars().mapToObj( i-> (char)i ).filter( c -> Character.isDigit(c) || c == '.' ).forEach( c -> result.append(c) );

    System.out.println( result ); //returns 19198.130810923.
}

Cells cannot be changed from within a VBA function used as a worksheet formula. Except via this workaround...

Put this function into a new module:

Function SetRGB(x As Range, R As Byte, G As Byte, B As Byte)
  On Error Resume Next
  x.Interior.Color = RGB(R, G, B)
  x.Font.Color = IIf(0.299 * R + 0.587 * G + 0.114 * B < 128, vbWhite, vbBlack)
End Function

Then use this formula in your sheet, for example in cell D2:

=HYPERLINK(SetRGB(D2;A2;B2;C2);"HOVER!")

Once you hover the mouse over the cell (try it!), the background color updates to the RGB taken from cells A2 to C2. The font color is a contrasting white or black.

As @Marc Claesen mentioned that one of the ways to write cache friendly code is to exploit the structure in which our data is stored. In addition to that another way to write cache friendly code is: change the way our data is stored; then write new code to access the data stored in this new structure.

This makes sense in the case of how database systems linearize the tuples of a table and store them. There are two basic ways to store the tuples of a table i.e. row store and column store. In row store as the name suggests the tuples are stored row wise. Lets suppose a table named Product being stored has 3 attributes i.e. int32_t key, char name[56] and int32_t price, so the total size of a tuple is 64 bytes.

We can simulate a very basic row store query execution in main memory by creating an array of Product structs with size N, where N is the number of rows in table. Such memory layout is also called array of structs. So the struct for Product can be like:

struct Product
{
   int32_t key;
   char name[56];
   int32_t price'
}

/* create an array of structs */
Product* table = new Product[N];
/* now load this array of structs, from a file etc. */

Similarly we can simulate a very basic column store query execution in main memory by creating an 3 arrays of size N, one array for each attribute of the Product table. Such memory layout is also called struct of arrays. So the 3 arrays for each attribute of Product can be like:

/* create separate arrays for each attribute */
int32_t* key = new int32_t[N];
char* name = new char[56*N];
int32_t* price = new int32_t[N];
/* now load these arrays, from a file etc. */

Now after loading both the array of structs (Row Layout) and the 3 separate arrays (Column Layout), we have row store and column store on our table Product present in our memory.

Now we move on to the cache friendly code part. Suppose that the workload on our table is such that we have an aggregation query on the price attribute. Such as

SELECT SUM(price)
FROM PRODUCT

For the row store we can convert the above SQL query into

int sum = 0;
for (int i=0; i<N; i++)
   sum = sum + table[i].price;

For the column store we can convert the above SQL query into

int sum = 0;
for (int i=0; i<N; i++)
   sum = sum + price[i];

The code for the column store would be faster than the code for the row layout in this query as it requires only a subset of attributes and in column layout we are doing just that i.e. only accessing the price column.

Suppose that the cache line size is 64 bytes.

In the case of row layout when a cache line is read, the price value of only 1(cacheline_size/product_struct_size = 64/64 = 1) tuple is read, because our struct size of 64 bytes and it fills our whole cache line, so for every tuple a cache miss occurs in case of a row layout.

In the case of column layout when a cache line is read, the price value of 16(cacheline_size/price_int_size = 64/4 = 16) tuples is read, because 16 contiguous price values stored in memory are brought into the cache, so for every sixteenth tuple a cache miss ocurs in case of column layout.

So the column layout will be faster in the case of given query, and is faster in such aggregation queries on a subset of columns of the table. You can try out such experiment for yourself using the data from TPC-H benchmark, and compare the run times for both the layouts. The wikipedia article on column oriented database systems is also good.

So in database systems, if the query workload is known beforehand, we can store our data in layouts which will suit the queries in workload and access data from these layouts. In the case of above example we created a column layout and changed our code to compute sum so that it became cache friendly.

Append IDs at the class declaration

.aclass, #hashone, #hashtwo{ ...codes... }
document.getElementById( "hashone" ).style.visibility = "hidden";

You have missed out the field name id in the second NOT LIKE. Try:

SELECT * FROM transactions WHERE id NOT LIKE '1%' AND id NOT LIKE '2%'

The AND in the where clause joins 2 full condition expressions such as id NOT LIKE '1%' and can't be used to list multiple values that the id is 'not like'.

With the help of this answer, I successfully solved the problem.

We are going to apply a fix in sdkmanager. It is a shell script. It is located at $android_sdk/tools/bin, where $android_sdk is where you unzipped the Android SDK.

1. Open sdkmanager in your favorite editor.

2. Locate the line which sets the DEFAULT_JVM_OPTSvariable. In my copy, it is at line 31:

   DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME"'
   

3. Append the following options to the variable: -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee. Please pay attention to the quotes. In my copy, the line becomes:

   DEFAULT_JVM_OPTS='"-Dcom.android.sdklib.toolsdir=$APP_HOME" -XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee'
   

4. Save the file and quit the editor.
5. Run the command again.

Here is the result:

$ sdkmanager --list

Hola! It works!

-- Edit: 2017-11-07 --

Please note that you may need to apply the fix above again after running sdkmanager --update, since the sdkmanager shell script may be overridden if the tools package is updated.

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

Why don't you want to remove the multiple attribute? The entire purpose of that attribute is to specify to the browser that multiple values may be selected from the given select element. If only a single value should be selected, remove the attribute and the browser will know to allow only a single selection.

Use the tools you have, that's what they're for.

From the Mozilla Developer Network:

There is no way to stop or break a forEach() loop other than by throwing an exception. If you need such behavior, the forEach() method is the wrong tool.

Early termination may be accomplished with:

• A simple loop
• A for...of loop
• Array.prototype.every()
• Array.prototype.some()
• Array.prototype.find()
• Array.prototype.findIndex()

The other Array methods: every(), some(), find(), and findIndex() test the array elements with a predicate returning a truthy value to determine if further iteration is required.

If your scrollView is a subview of a containerView of some type, then make sure that your scrollView is within the frame or bounds of the containerView. I had containerView.clipsToBounds = NO which still allowed me see the scrollView, but because scrollView wasn't within the bounds of containerView it wouldn't detect touch events.

For example:

containerView.frame = CGRectMake(0, 0, 200, 200);
scrollView.frame = CGRectMake(0, 200, 200, 200);
[containerView addSubview:scrollView];
scrollView.userInteractionEnabled = YES;

You will be able to see the scrollView but it won't receive user interactions.

Suppose you worked in feature/task1 with multiple commits.

1. Go to your project branch (project/my_project)

2. Create a new branch (feature/task1_bugfix)

   git checkout -b feature/task1_bugfix
   

3. Marge with the --squash option

   git merge --squash feature/task1
   

4. Create a single commit

   git commit -am "add single comments"
   

5. Push your branch

   git push --set-upstream origin feature/task1_bugfix
   

By convention, the directory src/main/resources contains the resources that will be used by the application. So Maven will include them in the final JAR.

Thus in your application, you will access them using the getResourceAsStream() method, as the resources are loaded in the classpath.

If you need to have them outside your application, do not store them in src/main/resources as they will be bundled by Maven. Of course, you can exclude them (using the link given by chkal) but it is better to create another directory (for example src/main/external-resources) in order to keep the conventions regarding the src/main/resources directory.

In the latter case, you will have to deliver the resources independently as your JAR file (this can be achieved by using the Assembly plugin). If you need to access them in your Eclipse environment, go to the Properties of your project, then in Java Build Path in Sources tab, add the folder (for example src/main/external-resources). Eclipse will then add this directory in the classpath.

You cannot invoke JavaScript functions in standard HTML attributes other than onXXX. Just assign it during window onload.

<script type="text/javascript">
    window.onload = function() {
        document.myform.action = get_action();
    }

    function get_action() {
        return form_action;
    }
</script>

<form name="myform">
    ...
</form>

You see that I've given the form a name, so that it's easily accessible in document.

Alternatively, you can also do it during submit event:

<script type="text/javascript">
    function get_action(form) {
        form.action = form_action;
    }
</script>

<form onsubmit="get_action(this);">
    ...
</form>

  } else if (elem.webkitRequestFullscreen) { /* Chrome, Safari & Opera */
      elem.webkitRequestFullscreen();
  } else if (elem.msRequestFullscreen) { /* IE/Edge */
      elem.msRequestFullscreen();
  }
}
//Internet Explorer 10 and earlier does not support the msRequestFullscreen() method.

Try df['quantity'] = df['quantity'] * -1.

I appreciate the answer provided, but I think it would be nice to take it a bit further.

The basic block animation from the documentation

[containerView layoutIfNeeded]; // Ensures that all pending layout operations have been completed
[UIView animateWithDuration:1.0 animations:^{
     // Make all constraint changes here
     [containerView layoutIfNeeded]; // Forces the layout of the subtree animation block and then captures all of the frame changes
}];

but really this is a very simplistic scenario. What if I want to animate subview constraints via the updateConstraints method?

An animation block that calls the subviews updateConstraints method

[self.view layoutIfNeeded];
[self.subView setNeedsUpdateConstraints];
[self.subView updateConstraintsIfNeeded];
[UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionLayoutSubviews animations:^{
    [self.view layoutIfNeeded];
} completion:nil];

The updateConstraints method is overridden in the UIView subclass and must call super at the end of the method.

- (void)updateConstraints
{
    // Update some constraints

    [super updateConstraints];
}

The AutoLayout Guide leaves much to be desired but it is worth reading. I myself am using this as part of a UISwitch that toggles a subview with a pair of UITextFields with a simple and subtle collapse animation (0.2 seconds long). The constraints for the subview are being handled in the UIView subclasses updateConstraints methods as described above.

in School,

public void addTeacherName(classroom classroom, String teacherName) {
    classroom.setTeacherName(teacherName);
}

BTW, use Pascal Case for class names. Also, I would suggest a Map<String, classroom> to map a classroom name to a classroom.

Then, if you use my suggestion, this would work

public void addTeacherName(String className, String teacherName) {
    classrooms.get(className).setTeacherName(teacherName);
}

From my answer here, thought this might be useful:

I tried many steps to get this issue corrected. There are so many sources for possible solutions to this issue that is is hard to filter out the sense from the nonsense. I finally found a good solution here:

Step 1: Identify the Database Version

$ mysql --version

You'll see some output like this with MySQL:

$ mysql  Ver 14.14 Distrib 5.7.16, for Linux (x86_64) using  EditLine wrapper

Or output like this for MariaDB:

mysql  Ver 15.1 Distrib 5.5.52-MariaDB, for Linux (x86_64) using readline 5.1

Make note of which database and which version you're running, as you'll use them later. Next, you need to stop the database so you can access it manually.

Step 2: Stopping the Database Server

To change the root password, you have to shut down the database server beforehand.

You can do that for MySQL with:

$ sudo systemctl stop mysql

And for MariaDB with:

$ sudo systemctl stop mariadb

Step 3: Restarting the Database Server Without Permission Checking

If you run MySQL and MariaDB without loading information about user privileges, it will allow you to access the database command line with root privileges without providing a password. This will allow you to gain access to the database without knowing it.

To do this, you need to stop the database from loading the grant tables, which store user privilege information. Because this is a bit of a security risk, you should also skip networking as well to prevent other clients from connecting.

Start the database without loading the grant tables or enabling networking:

$ sudo mysqld_safe --skip-grant-tables --skip-networking &

The ampersand at the end of this command will make this process run in the background so you can continue to use your terminal.

Now you can connect to the database as the root user, which should not ask for a password.

$ mysql -u root

You'll immediately see a database shell prompt instead.

MySQL Prompt

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

mysql>

MariaDB Prompt

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

Now that you have root access, you can change the root password.

Step 4: Changing the Root Password

mysql> FLUSH PRIVILEGES;

Now we can actually change the root password.

For MySQL 5.7.6 and newer as well as MariaDB 10.1.20 and newer, use the following command:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';

For MySQL 5.7.5 and older as well as MariaDB 10.1.20 and older, use:

mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');

Make sure to replace new_password with your new password of choice.

Note: If the ALTER USER command doesn't work, it's usually indicative of a bigger problem. However, you can try UPDATE ... SET to reset the root password instead.

[IMPORTANT] This is the specific line that fixed my particular issue:

mysql> UPDATE mysql.user SET authentication_string = PASSWORD('new_password') WHERE User = 'root' AND Host = 'localhost';

Remember to reload the grant tables after this.

In either case, you should see confirmation that the command has been successfully executed.

Query OK, 0 rows affected (0.00 sec)

The password has been changed, so you can now stop the manual instance of the database server and restart it as it was before.

Step 5: Restart the Database Server Normally

The tutorial goes into some further steps to restart the database, but the only piece I used was this:

For MySQL, use: $ sudo systemctl start mysql

For MariaDB, use:

$ sudo systemctl start mariadb

Now you can confirm that the new password has been applied correctly by running:

$ mysql -u root -p

The command should now prompt for the newly assigned password. Enter it, and you should gain access to the database prompt as expected.

Conclusion

You now have administrative access to the MySQL or MariaDB server restored. Make sure the new root password you choose is strong and secure and keep it in safe place.

Reason for error:

1. The query from p in dc.BlogPosts where p.BlogPostID == ID select p returns a sequence.

2. Single() tries to retrieve an element from the sequence returned in step1.

3. As per the exception - The sequence returned in step1 contains no elements.

4. Single() tries to retrieve an element from the sequence returned in step1 which contains no elements.

5. Since Single() is not able to fetch a single element from the sequence returned in step1, it throws an error.

Fix:

Make sure the query (from p in dc.BlogPosts where p.BlogPostID == ID select p)

returns a sequence with at least one element.

This is how I would go about it.

$posts = $this->post->orderBy('id', 'DESC')->get();

I need to do something like this I ended up going with the following solution.

I have a specific website URL that will open a page with two buttons

1) Button One go to website

2) Button Two go to application (iphone / android phone / tablet) you can fall back to a default location from here if the app is not installed (like another url or an app store)

3) cookie to remember users choice

    function set_cookie(name,value)
    {
       // js code to write cookie
    }
    function read_cookie(name) {
       // jsCode to read cookie
    }

    function goToApp(appLocation) {
        setTimeout(function() {
            window.location = appLocation;
              //this is a fallback if the app is not installed. Could direct to an app store or a website telling user how to get app


        }, 25);
        window.location = "custom-uri://AppShouldListenForThis";
    }

    function goToWeb(webLocation) {

Take a look at Simple JavaScript Inheritance and Inheritance Patterns in JavaScript.

The simplest method is probably functional inheritance but there are pros and cons.

My solution is to check the version number of pip and use the import the correct main function correctly

    import pip

    if int(pip.__version__.split('.')[0])>9:
        from pip._internal import main
    else:
        from pip import main
    def install(package):
        main(['install', package])

For swift 3 & 4

let customView = Bundle.main.loadNibNamed("CustomView", owner: nil, options: nil)?.first as? CustomView

Use the method "toArray()"

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
Object[] mStringArray = mStringList.toArray();

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

or you can do it like this: (mentioned in other answers)

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
String[] mStringArray = new String[mStringList.size()];
mStringArray = mStringList.toArray(mStringArray);

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

http://developer.android.com/reference/java/util/ArrayList.html#toArray()

The best way is to use a List within a List:

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

Below is an example for Angular 6

deleteAccount(email) {
            const header: HttpHeaders = new HttpHeaders()
                .append('Content-Type', 'application/json; charset=UTF-8')
                .append('Authorization', 'Bearer ' + sessionStorage.getItem('accessToken'));
            const httpOptions = {
                headers: header,
                body: { Email: email }
            };
            return this.http.delete<any>(AppSettings.API_ENDPOINT + '/api/Account/DeleteAccount', httpOptions);
        }

Considere the case that Java is Multiplatform:

int lastPath = fileName.lastIndexOf(File.separator);
if (lastPath!=-1){
    fileName = fileName.substring(lastPath+1);
}

Or this, it works quite well i think for what i needed. It's from here.

public IPAddress GetExternalIP()
{
    WebClient lol = new WebClient();
    string str = lol.DownloadString("http://www.ip-adress.com/");
    string pattern = "<h2>My IP address is: (.+)</h2>"
    MatchCollection matches1 = Regex.Matches(str, pattern);
    string ip = matches1(0).ToString;
    ip = ip.Remove(0, 21);
    ip = ip.Replace("

    ", "");
    ip = ip.Replace(" ", "");
    return IPAddress.Parse(ip);
}

I would go with x.equals(y) because that's consistent way to check equality for all classes.

As far as performance goes, equals is actually more expensive because it ends up calling intValue().

EDIT: You should avoid autoboxing in most cases. It can get really confusing, especially the author doesn't know what he was doing. You can try this code and you will be surprised by the result;

Integer a = 128;
Integer b = 128;

System.out.println(a==b);

You urls are not in the same repository, so you can't do it with the svn diff command.

svn: 'http://svn.boost.org/svn/boost/sandbox/boost/extension' isn't in the same repository as 'http://cloudobserver.googlecode.com/svn'

Another way you could do it, is export each repos using svn export, and then use the diff command to compare the 2 directories you exported.

// Export repositories
svn export http://svn.boost.org/svn/boost/sandbox/boost/extension/ repos1
svn export http://cloudobserver.googlecode.com/svn/branches/v0.4/Boost.Extension.Tutorial/libs/boost/extension/ repos2

// Compare exported directories
diff repos1 repos2 > file.diff

if you need double quoted JSON use JSON.stringify( object)

var $items = $('#firstName, #lastName,#phoneNumber,#address ')
var obj = {}
$items.each(function() {
    obj[this.id] = $(this).val();
})

var json= JSON.stringify( obj);

You need to check the return value against EOF, not against 1.

Note that in your example, you also used two different variable names, words and word, only declared words, and didn't declare its length, which should be 16 to fit the 15 characters read in plus a NUL character.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

text doesn't work with len function.

ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead. For more information, see Using Large-Value Data Types.

Here is how I create a tag:

private static final String TAG = SomeActivity.class.getSimpleName();
 Log.d(TAG, "some description");

You could use getCannonicalName

Here I have following TAG filters:

• any (*) View - VERBOSE
• any (*) Activity - VERBOSE
• any tag starting with Xyz(*) - ERROR
• System.out - SILENT (since I am using Log in my own code)

Here what I type in terminal:

$  adb logcat *View:V *Activity:V Xyz*:E System.out:S

Selecting is often unnecessary. Try this

Sub OneCell()
    Sheets("Sheet2").range("B1:B3").value = Sheets("Sheet1").range("A1:A3").value
End Sub

Try the out-of-the-box solution (ASP.NET MVC 4 or later):

@{
    var bundle = BundleTable.Bundles.GetRegisteredBundles().First(b => b.Path == "~/js");

    bundle.Include("~/Scripts/myFile.js");
}

Grepping the URL before and after might give you some peace of mind:

svn info | grep URL

  URL: svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
  Relative URL: (...doesn't matter...)

And checking on your version (to be >1.7) to ensure, svn relocate is the right thing to use:

svn --version

Lastly, adding to the above, if your repository url change also involves a change of protocol you might need to state the before and after url (also see here)

svn relocate svn://svnrepo.rz.mycompany.org/repos/trunk/DataPortal
    https://svngate.mycompany.org/svn/repos/trunk/DataPortal

All in one single line of course.Thereafter, get the good feeling, that all went smoothly:

svn info | grep URL:

If you feel like it, a bit more of self-assurance, the new svn repo URL is connected and working:

svn status --show-updates
svn diff

You could add the following Maven dependency.

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.1</version>
    </dependency>
    <!-- https://mvnrepository.com/artifact/org.apache.httpcomponents/httpmime -->
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpmime</artifactId>
        <version>4.5.1</version>
    </dependency>

You could use following import in your java code.

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGett;
import org.apache.http.impl.client.HttpClientBuilder;
import org.apache.http.client.methods.HttpUriRequest;

You could use following code block in your java code.

HttpClient client = HttpClientBuilder.create().build();
HttpUriRequest httpUriRequest = new HttpGet("http://example.domain/someuri");

HttpResponse response = client.execute(httpUriRequest);
System.out.println("Response:"+response);

You had several issues with your code.

1) Missing a closing brace, }, within your rules.

2) In this case, there is no reason to use a function for the required rule. By default, the plugin can handle checkbox and radio inputs just fine, so using true is enough. However, this will simply do the same logic as in your original function and verify that at least one is checked.

3) If you also want only a maximum of two to be checked, then you'll need to apply the maxlength rule.

4) The messages option was missing the rule specification. It will work, but the one custom message would apply to all rules on the same field.

5) If a name attribute contains brackets, you must enclose it within quotes.

DEMO: http://jsfiddle.net/K6Wvk/

$(document).ready(function () {

    $('#formid').validate({ // initialize the plugin
        rules: {
            'test[]': {
                required: true,
                maxlength: 2
            }
        },
        messages: {
            'test[]': {
                required: "You must check at least 1 box",
                maxlength: "Check no more than {0} boxes"
            }
        }
    });

});

ByteArrayInputStream

You can not do it as a member function, because the implicit this parameter is the left hand side of the <<-operator. (Hence, you would need to add it as a member function to the ostream-class. Not good :)

Could you do it as a free function without friending it? That's what I prefer, because it makes it clear that this is an integration with ostream, and not a core functionality of your class.

For those who were wondering about := & =

Significant difference between := and =, and that is that := works as a variable-assignment operator everywhere, while = only works that way in SET statements, and is a comparison operator everywhere else.

So SELECT @var = 1 + 1; will leave @var unchanged and return a boolean (1 or 0 depending on the current value of @var), while SELECT @var := 1 + 1; will change @var to 2, and return 2. [Source]

Please find the code in jsFiddle. It uses jQuery to modify the href of the link. You can use any other library in its place. It should work.

HTML

<a id="emailLnk" href="#">
    <img src="http://ssl.gstatic.com/gb/images/j_e6a6aca6.png">
</a>

JS

$(document).ready(function() {
    $("#emailLnk").attr('href',"mailto:[email protected]");
});?

UPDATE

Another code sample, if the id is known only during the click event

$(document).ready(function() {
    $("#emailLnk").click(function()
     {
         window.location.href = "mailto:[email protected]";
     });
});?

First of all, remove component folder, which you have to delete and then remove its entries which you have made in "ts" files.
