Programs & Examples On #Tortoisegit

you are using a smart quote “ instead of " here:

git.exe clone -v “ssh://
                ^^^ 

Make sure you use the plain-old-double-quote.

Following this guide I had the same issue. To expand on Eric Moore's ridiculously vague answer,

Right click > TortoiseGit > Settings > Network

Down the bottom in the "SSH" section, hit Browse and find your TortoiseGit\bin\TortoisePlink.exe file. In my case the path was under Programs as opposed to Program Files

Similar issue:

I gave passphrase when Git-cloned using SSH URL for git.
So this error now shows up, each time I opened VS Code on Windows 10

Below fixed the issue:

1 . Run the below command in CMD

setx SSH_ASKPASS "C:\Program Files\Git\mingw64\libexec\git-core\git-gui--askpass"
setx DISPLAY needs-to-be-defined

2 . Exit CMD & VS Code

3 . Reopen VS Code

4 . VS Code now shows a popup dialog where we can enter passpharse

Above commands are for Windows OS, similar instructions will work for Linux/MAC.

In my case, I forgot to add git to the respository name at the end.

If you are a windows 10 + TortoiseGit 2.7 user:

1. for the first time login, simply follow the prompts to enter your credentials and save password.
2. If you ever need to update your credentials, don't waste your time at the TortoiseGit settings. Instead, windows search>Credential Manager> Windows Credentials > find your git entry > Edit.

If another pull just works, it means your internet wasn't connected.

I was working on this type of function, maybe this will interests some of you ...

public boolean deleteFile(File file) throws IOException {
    if (file != null) {
        if (file.isDirectory()) {
            File[] files = file.listFiles();

            for (File f: files) {
                deleteFile(f);
            }
        }
        return Files.deleteIfExists(file.toPath());
    }
    return false;
}

C11 standard (n1570) §6.2.2.3 al1 p55 says :

A pointer to void may be converted to or from a pointer to any object type. A pointer to any object type may be converted to a pointer to void and back again; the result shall compare equal to the original pointer.

You can use this generic pointer to store a pointer to any object type, but you can't use usual arithmetic operations with it and you can't deference it.

You can hide a JPanel by calling setVisible(false). For example:

public static void main(String args[]){
    JFrame f = new JFrame();
    f.setLayout(new BorderLayout());
    final JPanel p = new JPanel();
    p.add(new JLabel("A Panel"));
    f.add(p, BorderLayout.CENTER);

    //create a button which will hide the panel when clicked.
    JButton b = new JButton("HIDE");
    b.addActionListener(new ActionListener(){
        public void actionPerformed(ActionEvent e){
                p.setVisible(false);
        }
    });

    f.add(b,BorderLayout.SOUTH);
    f.pack();
    f.setVisible(true);
}

In c, you could use fopen, and getch. Usually, if you can't be exactly sure of the length of the longest line, you could allocate a large buffer (e.g. 8kb) and almost be guaranteed of getting all lines.

If there's a chance you may have really really long lines and you have to process line by line, you could malloc a resonable buffer, and use realloc to double it's size each time you get close to filling it.

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

void handle_line(char *line) {
  printf("%s", line);
}

int main(int argc, char *argv[]) {
    int size = 1024, pos;
    int c;
    char *buffer = (char *)malloc(size);

    FILE *f = fopen("myfile.txt", "r");
    if(f) {
      do { // read all lines in file
        pos = 0;
        do{ // read one line
          c = fgetc(f);
          if(c != EOF) buffer[pos++] = (char)c;
          if(pos >= size - 1) { // increase buffer length - leave room for 0
            size *=2;
            buffer = (char*)realloc(buffer, size);
          }
        }while(c != EOF && c != '\n');
        buffer[pos] = 0;
        // line is now in buffer
        handle_line(buffer);
      } while(c != EOF); 
      fclose(f);           
    }
    free(buffer);
    return 0;
}

Try the following command:

openssl ciphers

This should produce a list of all of the ciphers supported in your version of openssl.

To see just a particular set of ciphers (e.g. just sslv3 ciphers) try:

openssl ciphers -ssl3

See https://www.openssl.org/docs/apps/ciphers.html for more info.

This form.php sample shows how to use PRG correct (when form is valid or not).

• It redirects to the same page, only when form is valid and action was performed.
• Redirection protects form from being resubmitted on page refresh.
• It uses session to not loose success messages you want to show when form is valid.
• There are two buttons for testing: "Valid submit", "Invalid submit". Try both and refresh page after that.

<?php
session_start();

function doSelfRedirect()
{
  header('Location:'.$_SERVER['PHP_SELF']);
  exit;
}

function setFlashMessage($msg)
{
  $_SESSION['message'] = $msg;
}

function getFlashMessage()
{
  if (!empty($_SESSION['message'])) {
    $msg = $_SESSION['message'];
    unset($_SESSION['message']);
  } else {
    $msg = null;
  }

  return $msg;
}

if ($_SERVER['REQUEST_METHOD'] === 'POST') {
  // Validation primitive example.
  if (empty($_POST['valid'])) {
    $formIsValid = false;
    setFlashMessage('Invalid form submit');
  } else {
    $formIsValid = true;
  }

  if ($formIsValid) {
    // Perform any actions here.
    // ...

    // Cool!
    setFlashMessage('Form is valid. Action performed.');

    // Prevent form resubmission.
    doSelfRedirect();
  }
}
?>
<h1>Hello form</h1>

<?php if ($msg = getFlashMessage()): ?>
  <div><?= $msg ?></div>
<?php endif; ?>

<form method="post">
  <input type="text" name="foo" value="bar"><br><br>
  <button type="submit" name="invalid" value="0">Invalid submit</button>
  <button type="submit" name="valid" value="1">Valid submit</button>
</form>

Assuming dateTime1 and dateTime2 are DateTime values:

var diffInSeconds = (dateTime1 - dateTime2).TotalSeconds;

In your case, you 'd use DateTime.Now as one of the values and the time in the list as the other. Be careful of the order, as the result can be negative if dateTime1 is earlier than dateTime2.

Your textbox code:

<input type="text" class="textboxclass" />

Your CSS code:

input[type="text"] {
height: 10px;
width: 80px;
}

or

.textboxclass {
height: 10px;
width: 80px;
}

So, first you select your element with attributes (look at first example) or classes(look last example). Later, you assign height and width values to your element.

Switch value must have an Integral type. Also, since you know that differenciating character is in position 7, you could switch on a.at(7). But you are not sure the user entered 8 characters. He may as well have done some typing mistake. So you are to surround your switch statement within a Try Catch. Something with this flavour

#include<iostream>
using namespace std;
int main() {
    string a;
    cin>>a;

    try
    {
    switch (a.at(7)) {
    case '1':
        cout<<"It pressed number 1"<<endl;
        break;
    case '2':
        cout<<"It pressed number 2"<<endl;
        break;
    case '3':
        cout<<"It pressed number 3"<<endl;
        break;
    default:
        cout<<"She put no choice"<<endl;
        break;
    }
    catch(...)
    {

    }
    }
    return 0;
}

The default clause in switch statement captures cases when users input is at least 8 characters, but not in {1,2,3}.

Alternatively, you can switch on values in an enum.

EDIT

Fetching 7th character with operator[]() does not perform bounds check, so that behavior would be undefined. we use at() from std::string, which is bounds-checked, as explained here.

Use Notepad ++ and use the option to Convert the file to UNIX format. That should solve this problem.

Add a style with the attribute text-decoration:none;:

There are a number of different ways of doing this.

Inline style:

<head>
<style type="text/css">
   a {
      text-decoration:none;
   }
</style>
</head>
<body>

<head>
<link rel="Stylesheet" href="stylesheet.css" />
</head>

is there a tag for don't render HTML until you hit the closing tag?

No, there is not. In HTML proper, there’s no way short of escaping some characters:

• & as &
• < as <

(Incidentally, there is no need to escape > but people often do it for reasons of symmetry.)

And of course you should surround the resulting, escaped HTML code within <pre><code>…</code></pre> to (a) preserve whitespace and line breaks, and (b) mark it up as a code element.

All other solutions, such as wrapping your code into a <textarea> or the (deprecated) <xmp> element, will break.¹

XHTML that is declared to the browser as XML (via the HTTP Content-Type header! — merely setting a DOCTYPE is not enough) could alternatively use a CDATA section:

<![CDATA[Your <code> here]]>

But this only works in XML, not in HTML, and even this isn’t a foolproof solution, since the code mustn’t contain the closing delimiter ]]>. So even in XML the simplest, most robust solution is via escaping.

¹ Case in point:

textarea {border: none; width: 100%;}

<textarea readonly="readonly">
  <p>Computer <textarea>says</textarea> <span>no.</span>
</textarea>

<xmp>
  Computer <xmp>says</xmp> <span>no.</span>
</xmp>

When you write your main function, you typically see one of two definitions:

• int main(void)
• int main(int argc, char **argv)

The second form will allow you to access the command line arguments passed to the program, and the number of arguments specified (arguments are separated by spaces).

The arguments to main are:

• int argc - the number of arguments passed into your program when it was run. It is at least 1.
• char **argv - this is a pointer-to-char *. It can alternatively be this: char *argv[], which means 'array of char *'. This is an array of C-style-string pointers.

Basic Example

For example, you could do this to print out the arguments passed to your C program:

#include <stdio.h>

int main(int argc, char **argv)
{
    for (int i = 0; i < argc; ++i)
    {
        printf("argv[%d]: %s\n", i, argv[i]);
    }
}

I'm using GCC 4.5 to compile a file I called args.c. It'll compile and build a default a.out executable.

[birryree@lilun c_code]$ gcc -std=c99 args.c

Now run it...

[birryree@lilun c_code]$ ./a.out hello there
argv[0]: ./a.out
argv[1]: hello
argv[2]: there

So you can see that in argv, argv[0] is the name of the program you ran (this is not standards-defined behavior, but is common. Your arguments start at argv[1] and beyond.

So basically, if you wanted a single parameter, you could say...

./myprogram integral

A Simple Case for You

And you could check if argv[1] was integral, maybe like strcmp("integral", argv[1]) == 0.

So in your code...

#include <stdio.h>
#include <string.h>

int main(int argc, char **argv)
{
    if (argc < 2) // no arguments were passed
    {
        // do something
    }

    if (strcmp("integral", argv[1]) == 0)
    {
        runIntegral(...); //or something
    }
    else
    {
        // do something else.
    }
}

Better command line parsing

Of course, this was all very rudimentary, and as your program gets more complex, you'll likely want more advanced command line handling. For that, you could use a library like GNU getopt.

Use formatting:

"%s" % (x)

Example:

x = time.ctime(); str = "%s" % (x); print str

Output: Thu Jan 11 20:40:05 2018

Add maven directory /bin to System variables under the name Path.

To check this, you can echo %PATH%

In Bootstrap 4, flexbox can be used to get a full height layout that fills the remaining space.

First of all, the container (parent) needs to be full height:

Option 1_ Add a class for min-height: 100%;. Remember that min-height will only work if the parent has a defined height:

html, body {
  height: 100%;
}

.min-100 {
    min-height: 100%;
}

https://codeply.com/go/dTaVyMah1U

Option 2_ Use vh units:

.vh-100 {
    min-height: 100vh;
}

https://codeply.com/go/kMahVdZyGj

Also of Bootstrap 4.1, the vh-100 and min-vh-100 classes are included in Bootstrap so there is no need to for the extra CSS

Then, use flexbox direction column d-flex flex-column on the container, and flex-grow-1 on any child divs (ie: row) that you want to fill the remaining height.

This solution works for both python and jython.

module os_identify.py:

import platform
import os

# This module contains functions to determine the basic type of
# OS we are running on.
# Contrary to the functions in the `os` and `platform` modules,
# these allow to identify the actual basic OS,
# no matter whether running on the `python` or `jython` interpreter.

def is_linux():
    try:
        platform.linux_distribution()
        return True
    except:
        return False

def is_windows():
    try:
        platform.win32_ver()
        return True
    except:
        return False

def is_mac():
    try:
        platform.mac_ver()
        return True
    except:
        return False

def name():
    if is_linux():
        return "Linux"
    elif is_windows():
        return "Windows"
    elif is_mac():
        return "Mac"
    else:
        return "<unknown>" 

Use like this:

import os_identify

print "My OS: " + os_identify.name()

document.getElementById("idframe").contentWindow.document.getElementById("idelement").value;

We have the same problem....but accidentally i checked folder properties and set something...

You have to check the properties of each folders that you're accessing..

1. right click folder

3. set the folder access : OWNER: create and delete files GROUP: access files OTHERS: access files

I hope that this is the solution......

Use range. In Python 2.x it returns a list so all you need is:

>>> range(11, 17)
[11, 12, 13, 14, 15, 16]

In Python 3.x range is a iterator. So, you need to convert it to a list:

>>> list(range(11, 17))
[11, 12, 13, 14, 15, 16]

Note: The second number is exclusive. So, here it needs to be 16+1 = 17

EDIT:

To respond to the question about incrementing by 0.5, the easiest option would probably be to use numpy's arange() and .tolist():

>>> import numpy as np
>>> np.arange(11, 17, 0.5).tolist()

[11.0, 11.5, 12.0, 12.5, 13.0, 13.5,
 14.0, 14.5, 15.0, 15.5, 16.0, 16.5]

for /F "tokens=1" %a in ('dir ^| findstr "File(s)"') do echo %a

Result:

C:\MyDir> for /F "tokens=1" %a in ('dir ^| findstr "File(s)"') do @set FILE_COUNT=%a

C:\MyDir> echo %FILE_COUNT%

i think it's pretty easy. just use this css

.content {
   width: 100%;
   height:(what u wanna give);
   float: left;
   position: fixed;
   overflow: auto;
   overflow-y: auto;
   overflow-x: none;
}

after this just give this class to ur div just like -

<div class="content">your stuff goes in...</div>

I would suggest reading this url http://docs.angularjs.org/api/ngResource/service/$resource

and revaluate how you are calling your delete method of your resources.

ideally you would want to be calling the delete of the resource item itself and by not passing the id of the resource into a catch all delete method

however $http.delete accepts a config object that contains both url and data properties you could either craft the query string there or pass an object/string into the data

maybe something along these lines

$http.delete('/roles/'+roleid, {data: input});

As pointed out by fyrye, the accepted answer pertains to older versions of MySQL in which ONLY_FULL_GROUP_BY had not yet been introduced. With MySQL 8.0.17 (used in this example), unless you disable ONLY_FULL_GROUP_BY you would get the following error message:

mysql> SELECT id, firstName, lastName FROM table_name GROUP BY firstName;

ERROR 1055 (42000): Expression #1 of SELECT list is not in GROUP BY clause and contains nonaggregated column 'mydatabase.table_name.id' which is not functionally dependent on columns in GROUP BY clause; this is incompatible with sql_mode=only_full_group_by

One way to work around this not mentioned by fyrye, but described in https://dev.mysql.com/doc/refman/5.7/en/group-by-handling.html, is to apply the ANY_VALUE() function to the columns which are not in the GROUP BY clause (id and lastName in this example):

mysql> SELECT ANY_VALUE(id) as id, firstName, ANY_VALUE(lastName) as lastName FROM table_name GROUP BY firstName;
+----+-----------+----------+
| id | firstName | lastName |
+----+-----------+----------+
|  1 | John      | Doe      |
|  2 | Bugs      | Bunny    |
+----+-----------+----------+
2 rows in set (0.01 sec)

As written in the aforementioned docs,

In this case, MySQL ignores the nondeterminism of address values within each name group and accepts the query. This may be useful if you simply do not care which value of a nonaggregated column is chosen for each group. ANY_VALUE() is not an aggregate function, unlike functions such as SUM() or COUNT(). It simply acts to suppress the test for nondeterminism.

Simple way :

• Auto move cursor to next edittext
• If edittext is last input -> hidden keyboard

Add this to edittext field in .xml file

android:inputType="textCapWords"

Don't try to be too sneaky, especially when it needlessly affects performance. If you really have a whole heap of comparisons to do, just format it nicely.

if (foobar === foo ||
    foobar === bar ||
    foobar === baz ||
    foobar === pew) {
     //do something
}

alternatively you can retrieve DOM properties with .prop

here is sample code for select box

if( ctrl.prop('type') == 'select-one' ) { // for single select }

if( ctrl.prop('type') == 'select-multiple' ) { // for multi select }

for textbox

  if( ctrl.prop('type') == 'text' ) { // for text box }

It is a code style convention; it indicates that a method returns a boolean value.

The question mark is a valid character at the end of a method name.

From this post:

Default template arguments are not part of the signature of a template

But one can do something like this:

#include <iostream>

struct Foo {
    template < class T,
               class std::enable_if < !std::is_integral<T>::value, int >::type = 0 >
    void f(const T& value)
    {
        std::cout << "Not int" << std::endl;
    }

    template<class T,
             class std::enable_if<std::is_integral<T>::value, int>::type = 0>
    void f(const T& value)
    {
        std::cout << "Int" << std::endl;
    }
};

int main()
{
    Foo foo;
    foo.f(1);
    foo.f(1.1);

    // Output:
    // Int
    // Not int
}

You can use zip with * to get transpose of a matrix:

>>> A = [[ 1, 2, 3],[ 4, 5, 6]]
>>> zip(*A)
[(1, 4), (2, 5), (3, 6)]
>>> lis  = [[1,2,3], 
... [4,5,6],
... [7,8,9]]
>>> zip(*lis)
[(1, 4, 7), (2, 5, 8), (3, 6, 9)]

If you want the returned list to be a list of lists:

>>> [list(x) for x in zip(*lis)]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]
#or
>>> map(list, zip(*lis))
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

Using replace() with regular expressions is the most flexible/powerful. It's also the only way to globally replace every instance of a search pattern in JavaScript. The non-regex variant of replace() will only replace the first instance.

For example:

var str = "foo gar gaz";

// returns: "foo bar gaz"
str.replace('g', 'b');

// returns: "foo bar baz"
str = str.replace(/g/gi, 'b');

In the latter example, the trailing /gi indicates case-insensitivity and global replacement (meaning that not just the first instance should be replaced), which is what you typically want when you're replacing in strings.

To remove characters, use an empty string as the replacement:

var str = "foo bar baz";

// returns: "foo r z"
str.replace(/ba/gi, '');

C++ has no specific feature to do that. However, if you use a std::vector instead of an array (as you probably should do) then you can specify a value to initialise the vector with.

std::vector <char> v( 100, 42 );

creates a vector of size 100 with all values initialised to 42.

Another short way you could use is a pipe (%<>%) from the magrittr package. It converts the character column mycolumn to a factor.

library(magrittr)

mydf$mycolumn %<>% factor

npm install installs dependencies into the node_modules/ directory, for the node project you're working on. You can call install on another node.js project (module), to install it as a dependency for your project.

npm run build does nothing unless you specify what "build" does in your package.json file. It lets you perform any necessary building/prep tasks for your project, prior to it being used in another project.

npm build is an internal command and is called by link and install commands, according to the documentation for build:

This is the plumbing command called by npm link and npm install.

You will not be calling npm build normally as it is used internally to build native C/C++ Node addons using node-gyp.

I had to use required="required" along with the same name and type, and then validation worked fine.

<input type="radio" name="user-radio"  id="" value="User" required="required" />

<input type="radio" name="user-radio" id="" value="Admin" />

<input type="radio" name="user-radio" id="" value="Guest" /> 

Since the reduce method has been removed from the built in function from Python3, don't forget to import the functools in your code. Please look at the code snippet below.

import functools
my_list = [10,15,20,25,35]
sum_numbers = functools.reduce(lambda x ,y : x+y , my_list)
print(sum_numbers)

If you want to run notepad inside your app you would probably be better of with a text editor component. There's obviously a basic text box that comes with WinForms, but I suspect more advanced components that offer Notepad functionality (or better) can be found on the interweb.

In Rails 4(Using HAML):

=f.text_field :first_name, class: 'form-control', autofocus: true, placeholder: 'First Name'

In short "How do I remove from a map while iterating it?"

• With old map impl: You can't

If you need to work with DTOs rather than entities directly then you should retrieve the existing Customer instance and map the updated fields from the DTO to that.

Customer entity = //load from DB
//map fields from DTO to entity

Adam Luter gave me the idea for this, but it actually turned out to be really simple:

img {
  width:  75px;
  height: auto;
}

IE6 now scales the image fine and this seems to be what all the other browsers use by default.

Thanks for both the answers though!

Try this for 4 PM from Monday to Sunday

You can check the description messgage displayed while you configuring in "Build periodically' under Jenkins. (Refer the screenshot given below)

"Would last have run at Sunday, November 17, 2019 4:00:05 PM IST; would next run at Monday, November 18, 2019 4:00:05 PM IST."

Screenshot

The seconds in the time " Monday, November 18, 2019 4:00:05 PM IST" refers to our current system seconds.

If you really don't like a recursion ... try shifting instead :)

$a = array(1,2,array(3,4, array(5,6,7), 8), 9);
$o = [];
for ($i=0; $i<count($a); $i++) {
    if (is_array($a[$i])) {
        array_splice($a, $i+1, 0, $a[$i]);
    } else {
        $o[] = $a[$i];
    }
}

Note: In this simple version, this does not support array keys.

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

Adding answer to show example of stripping multiple characters including \r using tr and using sed. And illustrating using hexdump.

In my case I had found that a command ending with awk print of the last item |awk '{print $2}' in the line included a carriage-return \r as well as quotes.

I used sed 's/["\n\r]//g' to strip both the carriage-return and quotes.

I could also have used tr -d '"\r\n'.

Interesting to note sed -z is needed if one wishes to remove \n line-feed chars.

$ COMMAND=$'\n"REBOOT"\r   \n'

$ echo "$COMMAND" |hexdump -C
00000000  0a 22 52 45 42 4f 4f 54  22 0d 20 20 20 0a 0a     |."REBOOT".   ..|

$ echo "$COMMAND" |tr -d '"\r\n' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

$ echo "$COMMAND" |sed 's/["\n\r]//g' |hexdump -C
00000000  0a 52 45 42 4f 4f 54 20  20 20 0a 0a              |.REBOOT   ..|

$ echo "$COMMAND" |sed -z 's/["\n\r]//g' |hexdump -C
00000000  52 45 42 4f 4f 54 20 20  20                       |REBOOT   |

And this is relevant: What are carriage return, linefeed, and form feed?

• CR == \r == 0x0d
• LF == \n == 0x0a

int small=a[0];
for (int x: a.length)
{
    if(a[x]<small)
        small=a[x];
}

I just find this solution but in my case it doesn't work:

@OneToMany(cascade = CascadeType.ALL, targetEntity = MyClass.class, mappedBy = "xxx", fetch = FetchType.LAZY, orphanRemoval = true) 

orphanRemoval = true has no effect.

It's pretty trivial to implement with native addon, so someone did that: https://github.com/ErikDubbelboer/node-sleep.git

If you need to remove white spaces at the end then here is a solution: https://www.geeksforgeeks.org/urlify-given-string-replace-spaces/

const stringQ1 = (string)=>{_x000D_
  //remove white space at the end _x000D_
  const arrString = string.split("")_x000D_
  for(let i = arrString.length -1 ; i>=0 ; i--){_x000D_
    let char = arrString[i];_x000D_
    _x000D_
    if(char.indexOf(" ") >=0){_x000D_
     arrString.splice(i,1)_x000D_
    }else{_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
_x000D_
  let start =0;_x000D_
  let end = arrString.length -1;_x000D_
  _x000D_
_x000D_
  //add %20_x000D_
  while(start < end){_x000D_
    if(arrString[start].indexOf(' ') >=0){_x000D_
      arrString[start] ="%20"_x000D_
      _x000D_
    }_x000D_
    _x000D_
    start++;_x000D_
  }_x000D_
  _x000D_
  return arrString.join('');_x000D_
}_x000D_
_x000D_
console.log(stringQ1("Mr John Smith   "))

I improved with one check iteration the good code of Hors Sujet to avoid including folders in the result array:

function getDirContents($dir, &$results = array()){

    $files = scandir($dir);

    foreach($files as $key => $value){
        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(is_dir($path) == false) {
            $results[] = $path;
        }
        else if($value != "." && $value != "..") {
            getDirContents($path, $results);
            if(is_dir($path) == false) {
                $results[] = $path;
            }   
        }
    }
    return $results;

}

As an alternative to @Mark Byers' approach, you can use while True:

guess = 50     # this should be outside the loop, I think
while True:    # infinite loop
    n = raw_input("\n\nTrue, False or Correct?: ")
    if n == "Correct":
        break  # stops the loop
    elif n == "True":
        # etc.

I don't recommend storing passwords in a script, but this is a way to what you indicate:

use 5.010;
my %user_table = ( tom => '123!', frank => '321!' );

say ( $user_table{ $name } eq $password ? 'You have gained access.'
    :                                     'Access denied!'
    );

Any time you want to enforce an association like this, it's a good idea to think of a table, and the most common form of table in Perl is the hash.

A much better way is to use inline-block, because you don't need to use clear:both at the end of your list anymore.

Try this:

<ul>
    <li>
        <a href="#">some item</a>
    </li>
    <li>
        <a href="#">another item</a>
    </li>
</ul>

CSS:

ul > li{
    display:inline-block;
}

Here is how you would do this with a nested list comprehension:

[[float(y) for y in x] for x in l]

This would give you a list of lists, similar to what you started with except with floats instead of strings. If you want one flat list then you would use [float(y) for x in l for y in x].

Actually I think using plain slices is the best solution in this case:

for i in range(0, len(data), 100):
    chunk = data[i:i + 100]
    ...

If you want to avoid copying the slices, you could use itertools.islice(), but it doesn't seem to be necessary here.

The itertools() documentation also contains the famous "grouper" pattern:

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

You would need to modify it to treat the last chunk correctly, so I think the straight-forward solution using plain slices is preferable.

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

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

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

Since you ask for other better ways to handle the problem, here's another way using data.table:

require(data.table) ## 1.9.2+
setDT(df)
df[a %in% c(0,1,3,4) | c == 4, g := 3L]
df[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]

Note the order of conditional statements is reversed to get g correctly. There's no copy of g made, even during the second assignment - it's replaced in-place.

On larger data this would have better performance than using nested if-else, as it can evaluate both 'yes' and 'no' cases, and nesting can get harder to read/maintain IMHO.

Here's a benchmark on relatively bigger data:

# R version 3.1.0
require(data.table) ## 1.9.2
require(dplyr)
DT <- setDT(lapply(1:6, function(x) sample(7, 1e7, TRUE)))
setnames(DT, letters[1:6])
# > dim(DT) 
# [1] 10000000        6
DF <- as.data.frame(DT)

DT_fun <- function(DT) {
    DT[(a %in% c(0,1,3,4) | c == 4), g := 3L]
    DT[a %in% c(2,5,7) | (a==1 & b==4), g := 2L]
}

DPLYR_fun <- function(DF) {
    mutate(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

BASE_fun <- function(DF) { # R v3.1.0
    transform(DF, g = ifelse(a %in% c(2,5,7) | (a==1 & b==4), 2L, 
            ifelse(a %in% c(0,1,3,4) | c==4, 3L, NA_integer_)))
}

system.time(ans1 <- DT_fun(DT))
#   user  system elapsed 
#  2.659   0.420   3.107 

system.time(ans2 <- DPLYR_fun(DF))
#   user  system elapsed 
# 11.822   1.075  12.976 

system.time(ans3 <- BASE_fun(DF))
#   user  system elapsed 
# 11.676   1.530  13.319 

identical(as.data.frame(ans1), as.data.frame(ans2))
# [1] TRUE

identical(as.data.frame(ans1), as.data.frame(ans3))
# [1] TRUE

Not sure if this is an alternative you'd asked for, but I hope it helps.

Go to phpmyadmin and click on the database you have already created form the left side bar. Then you can see a privilege option at the top.. There you can add a new user..

If you are not having any database yet go to phpmyadmin and select databases and create a database by simply giving database name in the filed and press go.

Don't forget to run cmd as admin.

Consider a more pragmatic approach to the question of "doing it correctly".

console.log("about to bind scroll fx");

$(window).scroll(function() {

       console.log("scroll bound, loop through div's");

       $('div').each(function(){

If both of those logs output correctly, then its likely the problem exists in your var declaration. To debug that, consider breaking it out into several lines:

var id='#'+$(this).attr('id');

console.log(id);

var off=$(id).offset().top;
var hei=$(id).height();
var winscroll=$(window).scrollTop();
var dif=hei+off-($(window).height());

By doing this, at least during debugging, you may find that the var id is undefined, causing errors throughout the rest of the code. Is it possible some of your div tags do not have id's?

If all you need is a user provided dictionary, possible better solution is json.loads. The main limitation is that json dicts requires string keys. Also you can only provide literal data, but that is also the case for literal_eval.

It was in a slightly different location for me than those listed above

\Users\[user]\AppData\Roaming\SQL Developer\system3.2.20.09.87\o.jdeveloper.db.connection.11.1.1.4.37.59.48\connections.xml

This might sound like a really basic "DUH" answer, but make sure that the column you're using to Lookup from on the merging file is actually full of unique values!

I noticed earlier today that PowerQuery won't throw you an error (like in PowerPivot) and will happily allow you to run a Many-Many merge. This will result in multiple rows being produced for each record that matches with a non-unique value.

If you want to format it with manually set symbols, use this:

DecimalFormatSymbols decimalFormatSymbols = new DecimalFormatSymbols();
decimalFormatSymbols.setDecimalSeparator('.');
decimalFormatSymbols.setGroupingSeparator(',');
DecimalFormat decimalFormat = new DecimalFormat("#,##0.00", decimalFormatSymbols);
System.out.println(decimalFormat.format(1237516.2548)); //1,237,516.25

Locale-based formatting is preferred, though.

It sounds like your table has no key. You should be able to simply try the INSERT: if it’s a duplicate then the key constraint will bite and the INSERT will fail. No worries: you just need to ensure the application doesn't see/ignores the error. When you say 'primary key' you presumably mean IDENTITY value. That's all very well but you also need a key constraint (e.g. UNIQUE) on your natural key.

Also, I wonder whether your procedure is doing too much. Consider having separate procedures for 'create' and 'read' actions respectively.

Forward proxies grant the client anonymity (i.e, think Tor).

Reverse proxies grant back end servers anonymity (i.e, think servers behind a DMZ).

Lets look at some test cases - try running the following expressions in your JS console:

"a" < "b"

"aa" < "ab"

"aaa" < "aab"

All return true.

JavaScript compares strings character by character and "a" comes before "b" in the alphabet - hence less than.

In your case it works like so -

1 . "a?aaa" < "?a?b"

compares the first two "a" characters - all equal, lets move to the next character.

2 . "a?a??aa" < "a?b??"

compares the second characters "a" against "b" - whoop! "a" comes before "b". Returns true.

Here's a simpler solution: install python-chromedrive package, import it in your script, and it's done.

Step by step:
1. pip install chromedriver-binary
2. import the package

from selenium import webdriver
import chromedriver_binary  # Adds chromedriver binary to path

driver = webdriver.Chrome()
driver.get("http://www.python.org")

A TreeMap is probably the most straightforward way of doing this. You use it exactly like a normal Map. i.e.

Map<Float,String> mySortedMap = new TreeMap<Float,MyObject>();
// Put some values in it
mySortedMap.put(1.0f,"One");
mySortedMap.put(0.0f,"Zero");
mySortedMap.put(3.0f,"Three");

// Iterate through it and it'll be in order!
for(Map.Entry<Float,String> entry : mySortedMap.entrySet()) {
    System.out.println(entry.getValue());
} // outputs Zero One Three 

It's worth taking a look at the API docs, http://download.oracle.com/javase/6/docs/api/java/util/TreeMap.html to see what else you can do with it.

Set default date in initialization:

$("#date").datepicker({
    defaultDate: '01/26/2014'
});

I needed to reload the state to make scrollbars work. They did not work when coming through another state - 'registration'. If the app was force closed after registration and opened again, i.e. it went directly to 'home' state, the scrollbars worked. None of the above solutions worked.

When after registration, I replaced:

$state.go("home");

with

window.location = "index.html"; 

The app reloaded, and the scrollbars worked.

just to not forget the format method

String s = String.format("%s%s%s%s%s", a, b, c, d, e);

(%1.1s%1.1s%1.1s%1.1s%1.1s if you only want the first digit of each number...)

You can use $addToSet with the aggregation framework to count distinct objects.

For example:

db.collectionName.aggregate([{
    $group: {_id: null, uniqueValues: {$addToSet: "$fieldName"}}
}])

It's wonderful to finally have this solved without using a hack.

Here is an example:

#include <iostream>

void by_val(int arg) { arg += 2; }
void by_ref(int&arg) { arg += 2; }

int main()
{
    int x = 0;
    by_val(x); std::cout << x << std::endl;  // prints 0
    by_ref(x); std::cout << x << std::endl;  // prints 2

    int y = 0;
    by_ref(y); std::cout << y << std::endl;  // prints 2
    by_val(y); std::cout << y << std::endl;  // prints 2
}

It depends on the kind of numbers and what you will allow. Handling numbers with decimals is more difficult than simple integers. Handling situations where multiple cultures are allowed is more complicated again.

The basics are these:

• Handle the "keypress" event for the text box. When a character which is not allowed has been pressed, cancel further processing of the event so the browser doesn't add it to the textbox.
• While handling "keypress", it is often useful to simple create the potential new string based on the key that was pressed. If the string is a valid number, allow the kepress. Otherwise, toss the keypress. This can greatly simplify some of the work.
• Potentially handle the "keydown" event if you're concerned with keys that "keypress" doesn't handle.

You can use the PHP string function implode()

Like,

<?php
  $sports=$_POST['sports'];;
  $festival=$_POST['festival'];
  $food=$_POST['food'];
  $array=[$sports,$festival,$food];
  $string=implode('|',$array);
  echo $string;
?>

If, for example, $sports='football'; $festival='janmastami'; $food='biriyani';

Then output would be:

football|janmastami|biriyani

For more details on PHP implode() function refer to w3schools

setx path "%PATH%; C:\Program Files (x86)\Microsoft Office\root\Office16" /m

This should do the appending to the System Environment Variable Path without any extras added, and keeping the original intact without any loss of data. I have used this command to correct the issue that McAfee's Web Control does to Microsoft's Outlook desktop client.

The quotations are used in the path value because command line sees spaces as a delimiter, and will attempt to execute next value in the command line. The quotations override this behavior and handles everything inside the quotations as a string.

• writelines expects an iterable of strings
• write expects a single string.

line1 + "\n" + line2 merges those strings together into a single string before passing it to write.

Note that if you have many lines, you may want to use "\n".join(list_of_lines).

If i understand you correctly, (i probably don't)

'SELECT @RowCount = COUNT(*)
                   FROM dbo.Comm_Services
                   WHERE CompanyId = ' + CAST(@CompanyId AS CHAR) + '
                   AND ' + @condition

Let's say we have a single byte:

0110110

Applying a single left bitshift gets us:

1101100

The leftmost zero was shifted out of the byte, and a new zero was appended to the right end of the byte.

The bits don't rollover; they are discarded. That means if you left shift 1101100 and then right shift it, you won't get the same result back.

Shifting left by N is equivalent to multiplying by 2^N.

Shifting right by N is (if you are using ones' complement) is the equivalent of dividing by 2^N and rounding to zero.

Bitshifting can be used for insanely fast multiplication and division, provided you are working with a power of 2. Almost all low-level graphics routines use bitshifting.

For example, way back in the olden days, we used mode 13h (320x200 256 colors) for games. In Mode 13h, the video memory was laid out sequentially per pixel. That meant to calculate the location for a pixel, you would use the following math:

memoryOffset = (row * 320) + column

Now, back in that day and age, speed was critical, so we would use bitshifts to do this operation.

However, 320 is not a power of two, so to get around this we have to find out what is a power of two that added together makes 320:

(row * 320) = (row * 256) + (row * 64)

Now we can convert that into left shifts:

(row * 320) = (row << 8) + (row << 6)

For a final result of:

memoryOffset = ((row << 8) + (row << 6)) + column

Now we get the same offset as before, except instead of an expensive multiplication operation, we use the two bitshifts...in x86 it would be something like this (note, it's been forever since I've done assembly (editor's note: corrected a couple mistakes and added a 32-bit example)):

mov ax, 320; 2 cycles
mul word [row]; 22 CPU Cycles
mov di,ax; 2 cycles
add di, [column]; 2 cycles
; di = [row]*320 + [column]

; 16-bit addressing mode limitations:
; [di] is a valid addressing mode, but [ax] isn't, otherwise we could skip the last mov

Total: 28 cycles on whatever ancient CPU had these timings.

Vrs

mov ax, [row]; 2 cycles
mov di, ax; 2
shl ax, 6;  2
shl di, 8;  2
add di, ax; 2    (320 = 256+64)
add di, [column]; 2
; di = [row]*(256+64) + [column]

12 cycles on the same ancient CPU.

Yes, we would work this hard to shave off 16 CPU cycles.

In 32 or 64-bit mode, both versions get a lot shorter and faster. Modern out-of-order execution CPUs like Intel Skylake (see http://agner.org/optimize/) have very fast hardware multiply (low latency and high throughput), so the gain is much smaller. AMD Bulldozer-family is a bit slower, especially for 64-bit multiply. On Intel CPUs, and AMD Ryzen, two shifts are slightly lower latency but more instructions than a multiply (which may lead to lower throughput):

imul edi, [row], 320    ; 3 cycle latency from [row] being ready
add  edi, [column]      ; 1 cycle latency (from [column] and edi being ready).
; edi = [row]*(256+64) + [column],  in 4 cycles from [row] being ready.

vs.

mov edi, [row]
shl edi, 6               ; row*64.   1 cycle latency
lea edi, [edi + edi*4]   ; row*(64 + 64*4).  1 cycle latency
add edi, [column]        ; 1 cycle latency from edi and [column] both being ready
; edi = [row]*(256+64) + [column],  in 3 cycles from [row] being ready.

Compilers will do this for you: See how GCC, Clang, and Microsoft Visual C++ all use shift+lea when optimizing return 320*row + col;.

The most interesting thing to note here is that x86 has a shift-and-add instruction (LEA) that can do small left shifts and add at the same time, with the performance as an add instruction. ARM is even more powerful: one operand of any instruction can be left or right shifted for free. So scaling by a compile-time-constant that's known to be a power-of-2 can be even more efficient than a multiply.

OK, back in the modern days... something more useful now would be to use bitshifting to store two 8-bit values in a 16-bit integer. For example, in C#:

// Byte1: 11110000
// Byte2: 00001111

Int16 value = ((byte)(Byte1 >> 8) | Byte2));

// value = 000011111110000;

In C++, compilers should do this for you if you used a struct with two 8-bit members, but in practice they don't always.

Here is the solution:

1. Login to DB;
2. Run a command show full processlist;to get the process id with status and query itself which causes the database hanging;
3. Select the process id and run a command KILL <pid>; to kill that process.

Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:

1. Login to MySQL;
2. Run a query Select concat('KILL ',id,';') from information_schema.processlist where user='user'; to print all processes with KILL command;
3. Copy the query result, paste and remove a pipe | sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.

install nvm and try it should help, use below command:-

CONVERT (VARCHAR(50), float_field,128)

As in this answer Custom HTTP Header for a specific file you can use <File> to enable CORS for a single file with this code:

  Header set Access-Control-Allow-Methods: "GET,POST,OPTIONS,DELETE,PUT"
</Files>

Sometimes You just open too much applications in Windows and make the gradle have no enough memory to start the daemon process.So when you come across with this situation,you can just close some applications such as Chrome and so on. Then restart your android studio.

Remember if your route is name-spaced, Like:

product GET  /products/:id(.:format)  spree/products#show

Then try :

helper.link_to("test", app.spree.product_path(Spree::Product.first), method: :get)

output

Spree::Product Load (0.4ms)  SELECT  "spree_products".* FROM "spree_products"  WHERE "spree_products"."deleted_at" IS NULL  ORDER BY "spree_products"."id" ASC LIMIT 1
=> "<a data-method=\"get\" href=\"/products/this-is-the-title\">test</a>" 

You can do objects the JavaScript way... It makes no sense but it works ;)

>>> def FakeObject():
...   def test():
...     print "foo"
...   FakeObject.test = test
...   return FakeObject
>>> x = FakeObject()
>>> x.test()
foo

Siblings

$(this).index() can be used to get the index of the clicked element if the elements are siblings.

<div id="container">
    <a href="#" class="link">1</a>
    <a href="#" class="link">2</a>
    <a href="#" class="link">3</a>
    <a href="#" class="link">4</a>
</div>

$('#container').on('click', 'a', function() {
  console.log($(this).index());
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div id="container">
  <a href="#" class="link">1</a>
  <a href="#" class="link">2</a>
  <a href="#" class="link">3</a>
  <a href="#" class="link">4</a>
</div>

Not siblings

If no argument is passed to the .index() method, the return value is an integer indicating the position of the first element within the jQuery object relative to its sibling elements.

Pass the selector to the index(selector).

$(this).index(selector);

Example:

Find the index of the <a> element that is clicked.

<tr>
    <td><a href="#" class="adwa">0001</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0002</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0003</a></td>
</tr>
<tr>
    <td><a href="#" class="adwa">0004</a></td>
</tr>

Fiddle

$('#table').on('click', '.adwa', function() {
    console.log($(this).index(".adwa"));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<table id="table">
    <thead>
        <tr>
            <th>vendor id</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td><a href="#" class="adwa">0001</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0002</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0003</a></td>
        </tr>
        <tr>
            <td><a href="#" class="adwa">0004</a></td>

As all have mentioned it is

request.getHeader("referer");

I would like to add some more details about security aspect of referer header in contrast with accepted answer. In Open Web Application Security Project(OWASP) cheat sheets, under Cross-Site Request Forgery (CSRF) Prevention Cheat Sheet it mentions about importance of referer header.

More importantly for this recommended Same Origin check, a number of HTTP request headers can't be set by JavaScript because they are on the 'forbidden' headers list. Only the browsers themselves can set values for these headers, making them more trustworthy because not even an XSS vulnerability can be used to modify them.

The Source Origin check recommended here relies on three of these protected headers: Origin, Referer, and Host, making it a pretty strong CSRF defense all on its own.

You can refer Forbidden header list here. User agent(ie:browser) has the full control over these headers not the user.

It is not mandatory to write that. It worked fine for me without (%matplotlib) magic function. I am using Sypder compiler, one that comes with in Anaconda.

Unfortunately, the methods you are using are unsupported in those browsers. To support my answer (this unsupportive behaviour) I have given links below.

onbeforeunload and onunload not working in opera... to support this

onbeforeunload in Opera

I encountered the same problem to configure Git on a collaborative development platform that I have to manage.

To solve it :

• I've Updated the release of Curl installed on the server. Download the last version on the website Download page of curland follow the installation proceedings Installation proceedings of curl

• Get back the certificate of the authority which delivers the certificate for the server.

• Add this certificate to the CAcert file used by curl. On my server it is located in /etc/pki/tls/certs/ca-bundle.crt.

• Configure git to use this certificate file by editing the .gitconfig file and set the sslcainfo path. sslcainfo= /etc/pki/tls/certs/ca-bundle.crt

• On the client machine you must get the certificate and configure the .gitconfig file too.

I hope this will help some of you.

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

You need some form of iteration here, as val (except when called with a function) only works on the first element:

$("input[placeholder]").val($("input[placeholder]").attr("placeholder"));

should be:

$("input[placeholder]").each( function () {
    $(this).val( $(this).attr("placeholder") );
});

or

$("input[placeholder]").val(function() {
    return $(this).attr("placeholder");
});

Polynomial time.

A polynomial is a sum of terms that look like Constant * x^k Exponential means something like Constant * k^x

(in both cases, k is a constant and x is a variable).

The execution time of exponential algorithms grows much faster than that of polynomial ones.

We can solve this issue by using Curl....

function my_curl_fun($url) {
 $ch = curl_init();
 curl_setopt($ch, CURLOPT_URL, $url);
 curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
 $data = curl_exec($ch);
 curl_close($ch);
 return $data;
}

$feed = 'http://................'; /* Insert URL here */
$data = my_curl_fun($feed);

This has been driving me insane for the past few days and couldn't get around it but have finally figured it out:

In my machine.config file I had an entry under <system.web>:

<deployment retail="true" />

This seems to override any other customError settings that you have specified in a web.config file, so setting the above entry to:

<deployment retail="false" />

now means that I can once again see the detailed error messages that I need to.

The machine.config is located at

32-bit

%windir%\Microsoft.NET\Framework\[version]\config\machine.config

64-bit

%windir%\Microsoft.NET\Framework64\[version]\config\machine.config 

Hope that helps someone out there and saves a few hours of hair-pulling.

You assigned a string "Red". Your Background property should be of type Color:

using System.Windows;
using System.ComponentModel;

namespace TestBackground88238
{
    public partial class Window1 : Window, INotifyPropertyChanged
    {

        #region ViewModelProperty: Background
        private Color _background;
        public Color Background
        {
            get
            {
                return _background;
            }

            set
            {
                _background = value;
                OnPropertyChanged("Background");
            }
        }
        #endregion

        //...//
}

Then you can use the binding to the SolidColorBrush like this:

public Window1()
{
    InitializeComponent();
    DataContext = this;

    Background = Colors.Red;
    Message = "This is the title, the background should be " + Background.toString() + ".";

}

not 100% sure about the .toString() method on Color-Object. It might tell you it is a Color-Class, but you will figur this out ;)

objectForKey: is an NSDictionary method. An NSDictionary is a collection class similar to an NSArray, except instead of using indexes, it uses keys to differentiate between items. A key is an arbitrary string you provide. No two objects can have the same key (just as no two objects in an NSArray can have the same index).

valueForKey: is a KVC method. It works with ANY class. valueForKey: allows you to access a property using a string for its name. So for instance, if I have an Account class with a property accountNumber, I can do the following:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setAccountNumber:anAccountNUmber];

NSNumber *anotherAccountNumber = [newAccount accountNumber];

Using KVC, I can access the property dynamically:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setValue:anAccountNumber forKey:@"accountNumber"];

NSNumber *anotherAccountNumber = [newAccount valueForKey:@"accountNumber"];

Those are equivalent sets of statements.

I know you're thinking: wow, but sarcastically. KVC doesn't look all that useful. In fact, it looks "wordy". But when you want to change things at runtime, you can do lots of cool things that are much more difficult in other languages (but this is beyond the scope of your question).

If you want to learn more about KVC, there are many tutorials if you Google especially at Scott Stevenson's blog. You can also check out the NSKeyValueCoding Protocol Reference.

Hope that helps.

Pattern! The group names a (sub)pattern for later use in the regex. See the documentation here for details about how such groups are used.

That's because you are dealing with floating point numbers. Division by zero returns Infinity, which is similar to NaN (not a number).

If you want to prevent this, you have to test tab[i] before using it. Then you can throw your own exception, if you really need it.

It seems many indie developers like me are desperately looking for an answer to these questions for years. Strangely, even after 5 years this question was asked, it seems the answer to this question is still not clear.

As far as I can see, there is not any official statement in Google AdMob documentation or website about how a developer can safely answer these questions. It seems developers are left on their own in the mystery about answering some legally binding questions about the SDK.

In their support forums they can advice questioners to reach out to Apple Support:

Hi there,

I believe it would be best for you to reach out to Apple Support for your concern as it tackles with Apple Submission Guidelines rather than our SDK.

Regards, Joshua Lagonera Mobile Ads SDK Team

Or they can say that it is out of their scope of support:

Hello Robert,

On this forum, we deal with Mobile Ads SDK related technical concerns only. We would not be able to address you question as this is out of scope for our team.

Regards, Deepika Uragayala Mobile Ads SDK Team

The only answer I could find from a "Google person" is about the 4th question. It is not in the AdMob forum but in the "Tag Manager" forum but still related. It is like so:

Hi Jorn,

Apple asks you about your use of IDFA when submitting your application (https://developer.apple.com/Library/ios/documentation/LanguagesUtilities/Conceptual/iTunesConnect_Guide/Chapters/SubmittingTheApp.html). For an app that doesn't display advertising, but includes the AdSupport framework for conversion attribution, you would select the appropriate checkbox(es). In respect to the Limit Ad Tracking stipulation, all of GTM's tags that utilize IDFA respect the limit ad tracking stipulations of the SDK.

Thanks,

Eric Burley Google Tag Manager.

Here is an Internet Archive link in case they remove this page.

Lastly, let me mention about AdMob's only statement I've seen about this issue (here is the Internet Archive link):

The Mobile Ads SDK for iOS utilizes Apple's advertising identifier (IDFA). The SDK uses IDFA under the guidelines laid out in the iOS developer program license agreement. You must ensure you are in compliance with the iOS developer program license agreement policies governing the use of this identifier.

In conclusion, it seems most developers using AdMob simply checks 1st and 4th checkmarks and submit their apps without being completely sure about what Google exactly does in its SDK and without any official information about it. I wish good luck to us all.

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

As you know angular.module( declared under angular.js file.So before accessing angular.module, you must have make it available by using <script src="lib/angular/angular.js"></script>(In your case) after then you can call angular.module. It will work.

like

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>My AngularJS App</title>
  <link rel="stylesheet" href="css/app.css"/>
<!-- In production use:
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.7/angular.min.js"></script>
  -->
  <script src="lib/angular/angular.js"></script>
  <script src="lib/angular/angular-route.js"></script>
  <script src="js/app.js"></script>
  <script src="js/services.js"></script>
  <script src="js/controllers.js"></script>
  <script src="js/filters.js"></script>
  <script src="js/directives.js"></script>

    <script>
        var app = angular.module('myApp',[]);

        app.directive('myDirective',function(){

            return function(scope, element,attrs) {
                element.bind('click',function() {alert('click')});
            };

        });
    </script>
</head>
<body ng-app="myApp">
    <div >
        <button my-directive>Click Me!</button>
    </div>
    <h1>{{2+3}}</h1>

</body>
</html>

I was using Android Pie and nothing seemed to worked so I played around with app:tabTextAppearance attribute. I know its not the perfect answer but might help someone.

<android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="fixed"
        app:tabTextAppearance="@style/TextAppearance.AppCompat.Caption" />

It is possible to upack without node installed using the following 7-Zip plugin:
http://www.tc4shell.com/en/7zip/asar/

Thanks @MayaPosch for mentioning that in this comment.

No Worries! I have found the solution! I just installed https://msdn.microsoft.com/en-us/windows/desktop/bg162891.aspx and it all worked fine :)

The easiest and purest method without relying on C headers is PyYaml (documentation), which can be installed via pip install pyyaml:

#!/usr/bin/env python

import yaml

with open("example.yaml", 'r') as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

And that's it. A plain yaml.load() function also exists, but yaml.safe_load() should always be preferred unless you explicitly need the arbitrary object serialization/deserialization provided in order to avoid introducing the possibility for arbitrary code execution.

Note the PyYaml project supports versions up through the YAML 1.1 specification. If YAML 1.2 specification support is needed, see ruamel.yaml as noted in this answer.

Here is another example you can try

private void dataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        if (e.ColumnIndex == dataGridView.Columns["Select"].Index)
        {
            dataGridView.EndEdit();

            if ((bool)dataGridView.Rows[e.RowIndex].Cells["Select"].Value)
            {
                //-- checking current select, needs to uncheck any other cells that are checked
                foreach(DataGridViewRow row in dataGridView.Rows)
                {
                    if (row.Index == e.RowIndex)
                    {
                        dataGridView.Rows[row.Index].SetValues(true);
                    }
                    else
                    {
                        dataGridView.Rows[row.Index].SetValues(false);
                    }
                }
            }
        }
    }

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

Ahhh, the stupid linesize ... Here is what I do in my profile.sql - works only on unixes:

echo SET LINES $(tput cols) > $HOME/.login_tmp.sql
@$HOME/.login_tmp.sql

if you find an equivalent for tput on Windows, it might work there as well

extension UIWindow {

    func visibleViewController() -> UIViewController? {
        if let rootViewController: UIViewController = self.rootViewController {
            return UIWindow.getVisibleViewControllerFrom(vc: rootViewController)
        }
        return nil
    }

    static func getVisibleViewControllerFrom(vc:UIViewController) -> UIViewController {
        if let navigationController = vc as? UINavigationController,
            let visibleController = navigationController.visibleViewController  {
            return UIWindow.getVisibleViewControllerFrom( vc: visibleController )
        } else if let tabBarController = vc as? UITabBarController,
            let selectedTabController = tabBarController.selectedViewController {
            return UIWindow.getVisibleViewControllerFrom(vc: selectedTabController )
        } else {
            if let presentedViewController = vc.presentedViewController {
                return UIWindow.getVisibleViewControllerFrom(vc: presentedViewController)
            } else {
                return vc
            }
        }
    }
}

Usage:

if let topController = window.visibleViewController() {
    println(topController)
}

This answer has long been answered, but I thought I would share my Decorator class which makes writing new decorators easy and compact.

from abc import ABCMeta, abstractclassmethod

class Decorator(metaclass=ABCMeta):
    """ Acts as a base class for all decorators """

    def __init__(self):
        self.method = None

    def __call__(self, method):
        self.method = method
        return self.call

    @abstractclassmethod
    def call(self, *args, **kwargs):
        return self.method(*args, **kwargs)

For one I think this makes the behavior of decorators very clear, but it also makes it easy to define new decorators very concisely. For the example listed above, you could then solve it as:

class MakeBold(Decorator):
    def call():
        return "<b>" + self.method() + "</b>"

class MakeItalic(Decorator):
    def call():
        return "<i>" + self.method() + "</i>"

@MakeBold()
@MakeItalic()
def say():
   return "Hello"

You could also use it to do more complex tasks, like for instance a decorator which automatically makes the function get applied recursively to all arguments in an iterator:

class ApplyRecursive(Decorator):
    def __init__(self, *types):
        super().__init__()
        if not len(types):
            types = (dict, list, tuple, set)
        self._types = types

    def call(self, arg):
        if dict in self._types and isinstance(arg, dict):
            return {key: self.call(value) for key, value in arg.items()}

        if set in self._types and isinstance(arg, set):
            return set(self.call(value) for value in arg)

        if tuple in self._types and isinstance(arg, tuple):
            return tuple(self.call(value) for value in arg)

        if list in self._types and isinstance(arg, list):
            return list(self.call(value) for value in arg)

        return self.method(arg)


@ApplyRecursive(tuple, set, dict)
def double(arg):
    return 2*arg

print(double(1))
print(double({'a': 1, 'b': 2}))
print(double({1, 2, 3}))
print(double((1, 2, 3, 4)))
print(double([1, 2, 3, 4, 5]))

Which prints:

2
{'a': 2, 'b': 4}
{2, 4, 6}
(2, 4, 6, 8)
[1, 2, 3, 4, 5, 1, 2, 3, 4, 5]

Notice that this example didn't include the list type in the instantiation of the decorator, so in the final print statement the method gets applied to the list itself, not the elements of the list.

I used

chooseCRANmirror(81)

it gives you a prompt to select the country. Then you can do a selection by typing the country mirror code specified there.

I implemented very fast Postgresq data loader with native libpq methods. Try my package https://www.nuget.org/packages/NpgsqlBulkCopy/

A view represents a virtual table. You can join multiple tables in a view and use the view to present the data as if the data were coming from a single table.

A stored procedure uses parameters to do a function... whether it is updating and inserting data, or returning single values or data sets.

Creating Views and Stored Procedures - has some information from Microsoft as to when and why to use each.

Say I have two tables:

• tbl_user, with columns: user_id, user_name, user_pw
• tbl_profile, with columns: profile_id, user_id, profile_description

So, if I find myself querying from those tables A LOT... instead of doing the join in EVERY piece of SQL, I would define a view like:

CREATE VIEW vw_user_profile
AS
  SELECT A.user_id, B.profile_description
  FROM tbl_user A LEFT JOIN tbl_profile B ON A.user_id = b.user_id
GO

Thus, if I want to query profile_description by user_id in the future, all I have to do is:

SELECT profile_description FROM vw_user_profile WHERE user_id = @ID

That code could be used in a stored procedure like:

CREATE PROCEDURE dbo.getDesc
    @ID int
AS
BEGIN
    SELECT profile_description FROM vw_user_profile WHERE user_id = @ID
END
GO

So, later on, I can call:

dbo.getDesc 25

and I will get the description for user_id 25, where the 25 is your parameter.

There is obviously a lot more detail, this is just the basic idea.

This works for the 2.3.0 version:

io.on('connection', socket => {
   const ip = socket.handshake.headers['x-forwarded-for'] || socket.conn.remoteAddress.split(":")[3];
   console.log(ip);
});

I had same problem, my issue was that downloaded Apache 2.4 but 32 bits. Then re-download 64bits version and it's works.

I hope it helps you

Quick answer on OSX, set your environment variables.

>export PGHOST=localhost

>export PGPORT=5432

Or whatever you need.

Use the TABLOCKX lock hint for your transaction. See this article for more information on locking.

You can do this:

.thing {
  border: 2px solid transparent;
}
.thing:hover {
  border: 2px solid green;
}

Thank you @Gorge Reith. Working off the solution provided by @George Reith, here is a function that furthers (1) separates out the individual 'hrefs' links (because they might be useful), (2) uses attributes as keys (since attributes are more descriptive), and (3) it's usable within Node.js without needing Chrome by using the 'jsdom' package:

const jsdom = require('jsdom') // npm install jsdom provides in-built Window.js without needing Chrome


// Function to map HTML DOM attributes to inner text and hrefs
function mapDOM(html_string, json) {
    treeObject = {}

    // IMPT: use jsdom because of in-built Window.js
    // DOMParser() does not provide client-side window for element access if coding in Nodejs
    dom = new jsdom.JSDOM(html_string)
    document = dom.window.document
    element = document.firstChild

    // Recursively loop through DOM elements and assign attributes to inner text object
    // Why attributes instead of elements? 1. attributes more descriptive, 2. usually important and lesser
    function treeHTML(element, object) {
        var nodeList = element.childNodes;
        if (nodeList != null) {
           if (nodeList.length) {
               object[element.nodeName] = []  // IMPT: empty [] array for non-text recursivable elements (see below)
               for (var i = 0; i < nodeList.length; i++) {
                   // if final text
                   if (nodeList[i].nodeType == 3) {
                       if (element.attributes != null) {
                           for (var j = 0; j < element.attributes.length; j++) {
                                if (element.attributes[j].nodeValue !== '' && 
                                    nodeList[i].nodeValue !== '') {
                                    if (element.attributes[j].name === 'href') { // separate href
                                        object[element.attributes[j].name] = element.attributes[j].nodeValue;
                                    } else {
                                        object[element.attributes[j].nodeValue] = nodeList[i].nodeValue;
                                    }

                                }
                           }
                       }
                   // else if non-text then recurse on recursivable elements
                   } else {
                       object[element.nodeName].push({}); // if non-text push {} into empty [] array
                       treeHTML(nodeList[i], object[element.nodeName][object[element.nodeName].length -1]);
                   }
               }
           }
        }
    }
    treeHTML(element, treeObject);

    return (json) ? JSON.stringify(treeObject) : treeObject;
}

Here is a query which you can use to search for anything in from your database as a search result ,

SELECT * FROM tbl_customer 
    WHERE CustomerName LIKE '%".$search."%'
    OR Address LIKE '%".$search."%' 
    OR City LIKE '%".$search."%' 
    OR PostalCode LIKE '%".$search."%' 
    OR Country LIKE '%".$search."%'

Using this code will help you search in for multiple columns easily

Escaping apostrophes and quotes

If you have an apostrophe or a quote in your string, you must either escape it or enclose the whole string in the other type of enclosing quotes. For example, here are some stings that do and don't work:

<string name="good_example">"This'll work"</string>
<string name="good_example_2">This\'ll also work</string>
<string name="bad_example">This doesn't work</string>
<string name="bad_example_2">XML encodings don&apos;t work</string>

How are you running the file? Is it from the command line or from an IDE? The directory that your executable is in is not necessarily your working directory.

Try using the full path name in the fopen and see if that fixes it. If so, then the problem is as described.

For example:

file = fopen("c:\\MyDirectory\\TestFile1.txt", "r");
file = fopen("/full/path/to/TestFile1.txt", "r");

Or open up a command window and navigate to the directory where your executable is, then run it manually.

As an aside, you can insert a simple (for Windows or Linux/UNIX/BSD/etc respectively):

system ("cd")
system("pwd")

before the fopen to show which directory you're actually in.

As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>) now exists.

Hope this work

How it sounds:

out = only initialize/fill a parameter (the parameter must be empty) return it out plain

ref = reference, standard parameter (maybe with value), but the function can modifiy it.

React uses event delegation with a single event listener on document for events that bubble, like 'click' in this example, which means stopping propagation is not possible; the real event has already propagated by the time you interact with it in React. stopPropagation on React's synthetic event is possible because React handles propagation of synthetic events internally.

Working JSFiddle with the fixes from below.

React Stop Propagation on jQuery Event

Use Event.stopImmediatePropagation to prevent your other (jQuery in this case) listeners on the root from being called. It is supported in IE9+ and modern browsers.

stopPropagation: function(e){
    e.stopPropagation();
    e.nativeEvent.stopImmediatePropagation();
},

• Caveat: Listeners are called in the order in which they are bound. React must be initialized before other code (jQuery here) for this to work.

jQuery Stop Propagation on React Event

Your jQuery code uses event delegation as well, which means calling stopPropagation in the handler is not stopping anything; the event has already propagated to document, and React's listener will be triggered.

// Listener bound to `document`, event delegation
$(document).on('click', '.stop-propagation', function(e){
    e.stopPropagation();
});

To prevent propagation beyond the element, the listener must be bound to the element itself:

// Listener bound to `.stop-propagation`, no delegation
$('.stop-propagation').on('click', function(e){
    e.stopPropagation();
});

Edit (2016/01/14): Clarified that delegation is necessarily only used for events that bubble. For more details on event handling, React's source has descriptive comments: ReactBrowserEventEmitter.js.

I used Nicks approach - I needed to check whether the Remote Tools for Visual Studio are installed or not, it seems a bit slow, but in a seperate thread this is fine for me. - here my extended code:

    private bool isRdInstalled() {
        ManagementObjectSearcher p = new ManagementObjectSearcher("SELECT * FROM Win32_Product");
        foreach (ManagementObject program in p.Get()) {
            if (program != null && program.GetPropertyValue("Name") != null && program.GetPropertyValue("Name").ToString().Contains("Microsoft Visual Studio 2012 Remote Debugger")) {
                return true;
            }
            if (program != null && program.GetPropertyValue("Name") != null) {
                Trace.WriteLine(program.GetPropertyValue("Name"));
            }
        }
        return false;
    }

You can try this:

<form action="/home">_x000D_
  _x000D_
  <input type="submit" value="cancel">_x000D_
  _x000D_
  <input type="submit" value="login" formaction="/login">_x000D_
  <input type="submit" value="signup" formaction="/signup">_x000D_
  _x000D_
</form>

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.

The problem here is that you cannot define the background color using a color selector, you need a drawable selector. So, the necessary changes would look like this:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item
        android:state_pressed="true"
        android:drawable="@drawable/selected_state" />
</selector>

You would also need to move that resource to the drawable directory where it would make more sense since it's not a color selector per se.

Then you would have to create the res/drawable/selected_state.xml file like this:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">
    <solid android:color="@color/semitransparent_white" />
</shape>

and finally, you would use it like this:

android:background="@drawable/selector"

Note: the reason why the OP was getting an image resource drawn is probably because he tried to just reference his resource that was still in the color directory but using @drawable so he ended up with an ID collision, selecting the wrong resource.

Hope this can still help someone even if the OP probably has, I hope, solved his problem by now.

This is what I put as a menu option where I made a button on a JFrame to display another JFrame. I wanted only the new frame to be visible, and not to destroy the one behind it. I initially hid the first JFrame, while the new one became visible. Upon closing of the new JFrame, I disposed of it followed by an action of making the old one visible again.

Note: The following code expands off of Ravinda's answer and ng is a JButton:

ng.addActionListener((ActionEvent e) -> {
    setVisible(false);
    JFrame j = new JFrame("NAME");
    j.setVisible(true);
    j.addWindowListener(new java.awt.event.WindowAdapter() {
        @Override
        public void windowClosing(java.awt.event.WindowEvent windowEvent) {
            setVisible(true);
        }
    });
});

Though this is an old question, I thought I'd post my answer anyway, if that helps someone in future

 JArray array = JArray.Parse(jsonString);
 foreach (JObject obj in array.Children<JObject>())
 {
     foreach (JProperty singleProp in obj.Properties())
     {
         string name = singleProp.Name;
         string value = singleProp.Value.ToString();
         //Do something with name and value
         //System.Windows.MessageBox.Show("name is "+name+" and value is "+value);
      }
 }

This solution uses Newtonsoft library, don't forget to include using Newtonsoft.Json.Linq;

You can do this the following two ways:

1) Using loop attribute in video element (mentioned in the first answer):

2) and you can use the ended media event:

window.addEventListener('load', function(){
    var newVideo = document.getElementById('videoElementId');
    newVideo.addEventListener('ended', function() {
        this.currentTime = 0;
        this.play();
    }, false);

    newVideo.play();

});

To get dynamic tagging to work with ajax, here's what I did.

Select2 version 3.5

This is easy in version 3.5 because it offers the createSearchChoice hook. It even works for multiple select, as long as multiple: true and tags: true are set.

HTML

<input type="hidden" name="locations" value="Whistler, BC" />

JS

$('input[name="locations"]').select2({
  tags: true,
  multiple: true,
  createSearchChoice: function(term, data) {
    if (!data.length)
      return { id: term, text: term };
    },
  ajax: {
    url: '/api/v1.1/locations',
    dataType: 'json'
  }
});

The idea here is to use select2's createSearchChoice hook which passes you both the term that the user entered and the ajax response (as data). If ajax returns an empty list, then tell select2 to offer the user-entered term as an option.

Demo: https://johnny.netlify.com/select2-examples/version3

Select2 version 4.X

Version 4.X doesn't have a createSearchChoice hook anymore, but here's how I did the same thing.

HTML

  <select name="locations" multiple>
    <option value="Whistler, BC" selected>Whistler, BC</option>
  </select>

JS

$('select[name="locations"]').select2({
  ajax: {
    url: '/api/v1.1/locations',
    dataType: 'json',
    data: function(params) {
      this.data('term', params.term);
      return params;
    },
    processResults: function(data) {
      if (data.length)
        return {
          results: data
        };
      else
        return {
          results: [{ id: this.$element.data('term'), text: this.$element.data('term') }]
        };
    }
  }
});

The ideas is to stash the term that the user typed into jQuery's data store inside select2's data hook. Then in select2's processResults hook, I check if the ajax response is empty. If it is, I grab the stashed term that the user typed and return it as an option to select2.

Demo: https://johnny.netlify.com/select2-examples/version4

Building on @JustinBarber's example and noting @eric.frederich's comment, if you want to format negative values like -$1,000.00 rather than $-1,000.00 and don't want to use locale:

def as_currency(amount):
    if amount >= 0:
        return '${:,.2f}'.format(amount)
    else:
        return '-${:,.2f}'.format(-amount)

try this code

Collections.sort(yourarraylist, new SortBasedOnName());



import java.util.Comparator;
import com.RealHelp.objects.FBFriends_Obj;
import com.RealHelp.ui.importFBContacts;

public class SortBasedOnName implements Comparator
{
public int compare(Object o1, Object o2) 
{

    FBFriends_Obj dd1 = (FBFriends_Obj)o1;// where FBFriends_Obj is your object class
    FBFriends_Obj dd2 = (FBFriends_Obj)o2;
    return dd1.uname.compareToIgnoreCase(dd2.uname);//where uname is field name
}

}

This function takes the difference between two dates and shows it in a date format yyyy-mm-dd. All you need is to execute the code below and then use the function. After executing you can use it like this

SELECT datedifference(date1, date2)
FROM ....
.

If you know you're always going to use bash, it's much easier to always use the double bracket conditional compound command [[ ... ]], instead of the Posix-compatible single bracket version [ ... ]. Inside a [[ ... ]] compound, word-splitting and pathname expansion are not applied to words, so you can rely on

if [[ $aug1 == "and" ]];

to compare the value of $aug1 with the string and.

If you use [ ... ], you always need to remember to double quote variables like this:

if [ "$aug1" = "and" ];

If you don't quote the variable expansion and the variable is undefined or empty, it vanishes from the scene of the crime, leaving only

if [ = "and" ]; 

which is not a valid syntax. (It would also fail with a different error message if $aug1 included white space or shell metacharacters.)

The modern [[ operator has lots of other nice features, including regular expression matching.

This is a one-liner but uses four atomic commands:

head -1000 file.txt > newfile.txt; tail +1000 file.txt > file.txt.tmp; cp file.txt.tmp file.txt; rm file.txt.tmp

The sumplest solution is:

From the project dir:

sudo chmod 777 -R .git/objects

what about this?

top -c -p <PID>

I though I'd add one more way. In my case I supply this to com.hazelcast.config.XmlConfigBuilder which only needs java.util.Properties to resolve some properties inside the Hazelcast XML configuration file, i.e. it only calls getProperty(String) method. So, this allowed me to do what I needed:

@RequiredArgsConstructor
public class SpringReadOnlyProperties extends Properties {

  private final org.springframework.core.env.Environment delegate;

  @Override
  public String getProperty(String key) {
    return delegate.getProperty(key);
  }

  @Override
  public String getProperty(String key, String defaultValue) {
    return delegate.getProperty(key, defaultValue);
  }

  @Override
  public synchronized String toString() {
    return getClass().getName() + "{" + delegate + "}";
  }

  @Override
  public boolean equals(Object o) {
    if (this == o) return true;
    if (o == null || getClass() != o.getClass()) return false;
    if (!super.equals(o)) return false;
    SpringReadOnlyProperties that = (SpringReadOnlyProperties) o;
    return delegate.equals(that.delegate);
  }

  @Override
  public int hashCode() {
    return Objects.hash(super.hashCode(), delegate);
  }

  private void throwException() {
    throw new RuntimeException("This method is not supported");
  }

  //all methods below throw the exception

  * override all methods *
}

P.S. I ended up not using this specifically for Hazelcast because it only resolves properties for XML file but not at runtime. Since I also use Spring, I decided to go with a custom org.springframework.cache.interceptor.AbstractCacheResolver#getCacheNames. This resolves properties for both situations, at least if you use properties in cache names.

The actual cause of this warning is that you have configured your project to run with an earlier JRE version then you have installed. Generally this occurs whenever you use old projects with newer JREs.

This will likely cause no trouble at all. But if you want to be really on the save side, you should install the correct, old JDK. You can find them here: http://www.oracle.com/technetwork/java/archive-139210.html

If you then restart eclipse you can go into Window > Preferences > Java > Installed JREs > Execution Environments and set for in your case J2SE-1.4 the [perfect match] as eclipse calls it.

this is my solution:

    public Bitmap Blend(Bitmap topImage1, Bitmap bottomImage1, PorterDuff.Mode Type) {

        Bitmap workingBitmap = Bitmap.createBitmap(topImage1);
        Bitmap topImage = workingBitmap.copy(Bitmap.Config.ARGB_8888, true);

        Bitmap workingBitmap2 = Bitmap.createBitmap(bottomImage1);
        Bitmap bottomImage = workingBitmap2.copy(Bitmap.Config.ARGB_8888, true);

        Rect dest = new Rect(0, 0, bottomImage.getWidth(), bottomImage.getHeight());
        new BitmapFactory.Options().inPreferredConfig = Bitmap.Config.ARGB_8888;
        bottomImage.setHasAlpha(true);
        Canvas canvas = new Canvas(bottomImage);
        Paint paint = new Paint();

        paint.setXfermode(new PorterDuffXfermode(Type));

        paint.setFilterBitmap(true);
        canvas.drawBitmap(topImage, null, dest, paint);
        return bottomImage;
    }

usage :

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.SCREEN));

or

imageView.setImageBitmap(Blend(topBitmap, bottomBitmap, PorterDuff.Mode.OVERLAY));

and the results :

Overlay mode :

Screen mode:

I would suggest instead of using

<input type='submit'>

use

<button type='submit'>

Button was introduced specifically bearing CSS styling in mind. You can now add the gradient background image to it or style it using CSS3 gradients.

Description

You can do this using jQuery's .scrollTop() and .offset() method

Check out my sample and this jsFiddle Demonstration

Sample

$(function() {
    $(document).scrollTop( $("#header").offset().top );  
});

More Information

• jsFiddle Demonstration
• jQuery.scrollTop()
• jQuery.offset()

If we don't provide any scope then the default scope is compile, If you want to confirm, simply go to Effective pom tab in eclipse editor, it will show you as compile.

Its possible using pseudo element (after).
I have added to the original code a

position:relative

#content{
  width: 100px;
  min-height: 100px;
  margin: 20px auto;
  border-style: ridge;
  border-color: #567498;
  border-spacing:10px;
  position:relative;
  background:#000;
}
#content:after {
  content: '';
  position: absolute;
  top: -15px;
  left: -15px;
  right: -15px;
  bottom: -15px;
  border: red 2px solid;
}

Of course, it doesn't necessarily have to be transmitted over TCP. I implemented HTTP on top of UDP, for use in the Satellite TV Broadcasting industry.

PermGen stands for Permanent Generation.

Here is a brief blurb on DDJ

In the GUI, select the "Advanced" checkbox. It should now show several entries below. Rename your mingw32-make.exe file to make.exe (you can just make a copy) and set the CMAKE_MAKE_PROGRAM filepath variable to the location of said file.

Of course it does. After replacing the variable, it reads [ !-z ], which is not a valid [ command. Use double quotes, or [[.

if [ ! -z "$errorstatus" ]

if [[ ! -z $errorstatus ]]

You can do this using lookahead and lookbehind:

var pattern = @"(?<=-)\d+(?=-)";
var replaced = Regex.Replace(text, pattern, "AA"); 

use .val(), it will return the value of the <input>

$("#spa").val().length > 0

And you had a typo, length not lenght.

With the global configuration that you have defined for the exec-maven-plugin:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4.0</version>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

No.The image will be loaded as usual and will still use the user’s bandwidth if you are considering the mobile phone user bandwidth saving.What u can do is to use media query and filter the devices that you want your image to be loaded.Your image must be set as a background image of a div,etc and NOT an tag since the the image tag will load the image regardless if the screen size and the media query set.

When compiling with support for arm64, this won't generate a warning:

I get questions a lot from designers about not only width but what height to use to 'keep everything above the fold'. Here is one answer I gave recently -

For width, I'm not a designer but I've read that 960px width is the way to go these days, because it lends itself to being divided into columns that look nice, and fits nicely within most displays. If you can, design a liquid layout - but this is not always practical depending on your designer, your CSS skills, the images and the amount of text.

(you always want there to be 65-80 characters per line, with a line-height of about 1.15). This is the optimal column width for text, and it has been proven to be much faster and pleasant to read than very wide or narrow columns)

As far as 'above the fold', I just have to caution against using any such concept on the web. Horizontal scrolling can and should be avoided, but vertical scrolling is something you cannot 100% avoid. All I can tell you is that on a 1024x768 display (at least 95% of users have that or higher) you should be OK with a fixed 600px high block. But there are many different display formats out there, the browser chrome can take up a lot of room, and not everybody maximizes the browser window.

here are some other sites that say more-or-less the same thing - but planning to get absolutely everything 'above the fold' for everyone is tough because then you might only have 400px or so, according to the actual statistics.

And finally a good long article that goes into great detail (I'd post more but SO says I am too noob) - How to design for Browser Sizes - baekdal.com

There are two approaches that I know of. The first is to tell the browser not to cache the page. Setting the Response to no cache takes care of that, however as you suspect the browser will often ignore this directive. The other approach is to set the date time of your response to a point in the future. I believe all browsers will correct this to the current time when they add the page to the cache, but it will show the page as newer when the comparison is made. I believe there may be some cases where a comparison is not made. I am not sure of the details and they change with each new browser release. Final note I have had better luck with pages that "refresh" themselves (another response directive). The refresh seems less likely to come from the cache.

Hope that helps.

If you are using Mac, go to System Preferences > Network and use your IP address instead of localhost. You can also use port number. In my case, I have a server running on port 1448 and I can preview 192.168.1.241:1448 using iPhone.

NB.: Now instead of

runProguard false

you'll need to use

minifyEnabled false

Most answers get you the current path and are context sensitive. In order to run your script from any directory, use the below snippet.

DIR="$( cd "$( dirname "$0" )" && pwd )"

By switching directories in a subshell, we can then call pwd and get the correct path of the script regardless of context.

You can then use $DIR as "$DIR/path/to/file"

private Random gen = new Random();
DateTime RandomDay()
{
    DateTime start = new DateTime(1995, 1, 1);
    int range = (DateTime.Today - start).Days;           
    return start.AddDays(gen.Next(range));
}

For better performance if this will be called repeatedly, create the start and gen (and maybe even range) variables outside of the function.

jQuery Validation Plugin already implements min and max rules, we just need to create an adapter for our custom attribute:

public class MaxAttribute : ValidationAttribute, IClientValidatable
{
    private readonly int maxValue;

    public MaxAttribute(int maxValue)
    {
        this.maxValue = maxValue;
    }

    public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
    {
        var rule = new ModelClientValidationRule();

        rule.ErrorMessage = ErrorMessageString, maxValue;

        rule.ValidationType = "max";
        rule.ValidationParameters.Add("max", maxValue);
        yield return rule;
    }

    public override bool IsValid(object value)
    {
        return (int)value <= maxValue;
    }
}

Adapter:

$.validator.unobtrusive.adapters.add(
   'max',
   ['max'],
   function (options) {
       options.rules['max'] = parseInt(options.params['max'], 10);
       options.messages['max'] = options.message;
   });

Min attribute would be very similar.

Using dummies::dummy():

library(dummies)

# example data
df1 <- data.frame(id = 1:4, year = 1991:1994)

df1 <- cbind(df1, dummy(df1$year, sep = "_"))

df1
#   id year df1_1991 df1_1992 df1_1993 df1_1994
# 1  1 1991        1        0        0        0
# 2  2 1992        0        1        0        0
# 3  3 1993        0        0        1        0
# 4  4 1994        0        0        0        1

UPDATE mytable SET title=TRIM(REPLACE(REPLACE(title, "\n", ""), "\t", ""));

I got it work by overriding annotation with XML file for Postgres. Annotation is kept for Oracle. In my opinion, in this case it would be best we override the mapping of this trouble-some enity with xml mapping. We can override single / multiple entities with xml mapping. So we would use annotation for our mainly-supported database, and a xml file for each other database.

Note: we just need to override one single class , so it is not a big deal. Read more from my example Example to override annotation with XML

Grant permissions for that user is needed

If a different library is fine for you, you could try org.json:

JSONObject object = new JSONObject(myJSONString);
String[] keys = JSONObject.getNames(object);

for (String key : keys)
{
    Object value = object.get(key);
    // Determine type of value and do something with it...
}

Here is another place where I like to use this pattern:

 while data in items:
     try
        data = json.loads(data)
     except ValueError as e:
        log error
     else:
        # work on the `data`

For SQL server, the following will return the first row from giving table.

declare @rowNumber int = 1;
    select TOP(@rowNumber) * from [dbo].[someTable];
EXCEPT
    select TOP(@rowNumber - 1) * from [dbo].[someTable];

You can loop through the values with something like this:

WHILE @constVar > 0
BEGIN
    declare @rowNumber int = @consVar;
       select TOP(@rowNumber) * from [dbo].[someTable];
    EXCEPT
       select TOP(@rowNumber - 1) * from [dbo].[someTable];  

       SET @constVar = @constVar - 1;    
END;

You will need to set the permissions every time you plug the converter in. I use PuTTY to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:

#!/bin/bash
sudo chmod 666 /dev/ttyUSB0

putty

P.S. I would never recommend that permissions are set to 777.

Or use a cast with split to uniform type of str

unique, counts = numpy.unique(str(a).split(), return_counts=True)

Follow this procedures

1 .Add MessageUI.Framework to project

2 . Import #import <MessageUI/MessageUI.h> in .h file.

3 . Copy this code for sending message

 if ([MFMessageComposeViewController canSendText]) {
    MFMessageComposeViewController *messageComposer =
    [[MFMessageComposeViewController alloc] init];
    NSString *message = @"Message!!!";
    [messageComposer setBody:message];
    messageComposer.messageComposeDelegate = self;
    [self presentViewController:messageComposer animated:YES completion:nil];
}

4 . Implement delegate method if you want to.

- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{


   ///your stuff here 

    [self dismissViewControllerAnimated:YES completion:nil];
}

Run And GO!

I had the same issue when I was using GIT bash to merge master branch in to my feature branch. I followed the following steps to overcome this.

1. press 'i' (To insert a merge message)
2. write your merge message
3. press esc button (To go back)
4. write ':wq' (write & quit)
5. then press enter

_.omit(thisIsObject,'Cow'); //It will return a new object

=> {'Cat' : 'Meow', 'Dog' : 'Bark'}  //result

If you want to modify the current object, assign the returning object to the current object.

thisIsObject = _.omit(thisIsObject,'Cow');

With pure JavaScript, use:

delete thisIsObject['Cow'];

Another option with pure JavaScript.

thisIsObject.cow = undefined;

thisIsObject = JSON.parse(JSON.stringify(thisIsObject ));

An alternative to AtomicInteger is to use an array (or any other object able to store a value):

final int ordinal[] = new int[] { 0 };
list.forEach ( s -> s.setOrdinal ( ordinal[ 0 ]++ ) );

But see the Stuart's answer: there might be a better way to deal with your case.

In many environments (e.g. Heroku), and as a convention, you can set the environment variable PORT to tell your web server what port to listen on.

So process.env.PORT || 3000 means: whatever is in the environment variable PORT, or 3000 if there's nothing there.

So you pass that to app.listen, or to app.set('port', ...), and that makes your server able to accept a "what port to listen on" parameter from the environment.

If you pass 3000 hard-coded to app.listen(), you're always listening on port 3000, which might be just for you, or not, depending on your requirements and the requirements of the environment in which you're running your server.

You could fairly easily run this through the CSharpCodeProvider with suitable fluff wrapping it (a type and a method, basically). Likewise you could go through VB etc - or JavaScript, as another answer has suggested. I don't know of anything else built into the framework at this point.

I'd expect that .NET 4.0 with its support for dynamic languages may well have better capabilities on this front.

You could also make the ajax call more generic, reusable, so you can call it from different CRUD(create, read, update, delete) tasks for example and treat the success cases from those calls.

makePostCall = function (url, data) { // here the data and url are not hardcoded anymore
   var json_data = JSON.stringify(data);

    return $.ajax({
        type: "POST",
        url: url,
        data: json_data,
        dataType: "json",
        contentType: "application/json;charset=utf-8"
    });
}

// and here a call example
makePostCall("index.php?action=READUSERS", {'city' : 'Tokio'})
    .success(function(data){
               // treat the READUSERS data returned
   })
    .fail(function(sender, message, details){
           alert("Sorry, something went wrong!");
  });

I was using old version 1.0.beta.6 of handlebars, i think somewhere during 1.1 - 1.3 this functionality was added, so updating to 1.3.0 solved the issue, here is the usage:

Usage:

{{#each object}}
  Key {{@key}} : Value {{this}}
{{/people}}

As of powershell 5.0, you can now use the -Depth parameter in Get-ChildItem!

You combine it with -Recurse to limit the recursion.

Get-ChildItem -Recurse -Depth 2

At the top first set up database connection as follow:

<?php
$mysqli = new mysqli("localhost", "username", "password", "database") or die($this->mysqli->error);
$query= $mysqli->query("SELECT PcID from PC");
?> 

Then include the following code in HTML inside form

<select name="selected_pcid" id='selected_pcid'>

            <?php 

             while ($rows = $query->fetch_array(MYSQLI_ASSOC)) {
                        $value= $rows['id'];
                ?>
                 <option value="<?= $value?>"><?= $value?></option>
                <?php } ?>
             </select>

However, if you are using materialize css or any other out of the box css, make sure that select field is not hidden or disabled.

So, over SMTP when a message is submitted, the SMTP envelope (sender, recipients, etc.) is different from the actual data of the message.

The Sender header is used to identify in the message who submitted it. This is usually the same as the From header, which is who the message is from. However, it can differ in some cases where a mail agent is sending messages on behalf of someone else.

The Return-Path header is used to indicate to the recipient (or receiving MTA) where non-delivery receipts are to be sent.

For example, take a server that allows users to send mail from a web page. So, [email protected] types in a message and submits it. The server then sends the message to its recipient with From set to [email protected]. The actual SMTP submission uses different credentials, something like [email protected]. So, the sender header is set to [email protected], to indicate the From header doesn't indicate who actually submitted the message.

In this case, if the message cannot be sent, it's probably better for the agent to receive the non-delivery report, and so Return-Path would also be set to [email protected] so that any delivery reports go to it instead of the sender.

If you are doing just that, a form submission to send e-mail, then this is probably a direct parallel with how you'd set the headers.
