If you use Notepad++, I would suggest installing the XML Tools plugin. You can beautify any XML content (indentation and line breaks) or linarize it. Also you can (auto-)validate your file and apply XSL transformation to it.

Download the latest zip and copy the extracted DLL to the plugins directory of your Notepad++ installation. Also, download the External libs and copy them to your %SystemRoot%\system32\ directory.

Faced the same issue and resolved by upgrading my Maven from 3.0.4 to 3.1.1. Please try with v3.1.1 or any higher version if available

unlink('path_to_filename'); will delete one file at a time.

If your whole files from directory is gone means you listed all files and deleted one by one in a loop.

Well you cannot de delete in the same page. You have to do with other page. create a page called deletepage.php which will contain script to delete and link to that page with 'file' as parameter.

foreach($FilesArray as $file)
{
    $FileLink = $Directory.'/'.$file['FileName'];

    if($OpenFileInNewTab) $LinkTarget = ' target="_blank"'; 
    else $LinkTarget = '';

    echo '<a href="'.$FileLink.'">'.$FileName.'</a>';
    echo '<a href="deletepage.php?file='.$fileName.'"><img src="images/icons/delete.gif"></a></td>';        
}

On the deletepage.php

//and also consider to check if the file exists as with the other guy suggested.
$filename = $_GET['file']; //get the filename
unlink('DIRNAME'.DIRECTORY_SEPARATOR.$filename); //delete it
header('location: backto prev'); //redirect back to the other page

If you don't want to navigate, then use ajax to make elegant.

This solution requires the Apache Commons IO library to be added to the build path. It works by reading the entire file and writing each line back but only if the search term is not contained.

public static void removeLineFromFile(File targetFile, String searchTerm)
        throws IOException
{
    StringBuffer fileContents = new StringBuffer(
            FileUtils.readFileToString(targetFile));
    String[] fileContentLines = fileContents.toString().split(
            System.lineSeparator());

    emptyFile(targetFile);
    fileContents = new StringBuffer();

    for (int fileContentLinesIndex = 0; fileContentLinesIndex < fileContentLines.length; fileContentLinesIndex++)
    {
        if (fileContentLines[fileContentLinesIndex].contains(searchTerm))
        {
            continue;
        }

        fileContents.append(fileContentLines[fileContentLinesIndex] + System.lineSeparator());
    }

    FileUtils.writeStringToFile(targetFile, fileContents.toString().trim());
}

private static void emptyFile(File targetFile) throws FileNotFoundException,
        IOException
{
    RandomAccessFile randomAccessFile = new RandomAccessFile(targetFile, "rw");

    randomAccessFile.setLength(0);
    randomAccessFile.close();
}

Facebook no longer supports custom parameters in sharer.php

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post from the url OG meta tags.

Use dialog/feeds instead of sharer.php

Official answer from fb team

@JsonFormat only work for standard format supported by the jackson version that you are using.

Ex :- compatible with any of standard forms ("yyyy-MM-dd'T'HH:mm:ss.SSSZ", "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", "EEE, dd MMM yyyy HH:mm:ss zzz", "yyyy-MM-dd")) for jackson 2.8.6

Let me clear two points here :

• firstly non-default argument should not follow default argument , it means you can't define (a=b,c) in function the order of defining parameter in function are :
  • positional parameter or non-default parameter i.e (a,b,c)
  • keyword parameter or default parameter i.e (a="b",r="j")
  • keyword-only parameter i.e (*args)
  • var-keyword parameter i.e (**kwargs)

def example(a, b, c=None, r="w" , d=[], *ae, **ab):

(a,b) are positional parameter

(c=none) is optional parameter

(r="w") is keyword parameter

(d=[]) is list parameter

(*ae) is keyword-only

(**ab) is var-keyword parameter

• now secondary thing is if i try something like this : def example(a, b, c=a,d=b):

argument is not defined when default values are saved,Python computes and saves default values when you define the function

c and d are not defined, does not exist, when this happens (it exists only when the function is executed)

"a,a=b" its not allowed in parameter.

I know this question has been answered but I also see there is another way missing which I would like to cover it.There are multiple ways to achieve this.

1- innerHTML

document.getElementById("ShowButton").innerHTML = 'Show Filter';

You can insert HTML into this. But the disadvantage of this method is, it has cross site security attacks. So for adding text, its better to avoid this for security reasons.

2- innerText

document.getElementById("ShowButton").innerText = 'Show Filter';

This will also achieve the result but its heavy under the hood as it requires some layout system information, due to which the performance decreases. Unlike innerHTML, you cannot insert the HTML tags with this. Check Performance Here

3- textContent

document.getElementById("ShowButton").textContent = 'Show Filter';

This will also achieve the same result but it doesn't have security issues like innerHTML as it doesn't parse HTML like innerText. Besides, it is also light due to which performance increases.

So if a text has to be added like above, then its better to use textContent.

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

Heredoc may be an option, see example 2 here: http://php.net/manual/en/language.types.string.php

Had the same problem when updating my mac to macOS Catalina, while using pipenv. Pipenv creates and manages a virtualenv for you, so the earlier suggestion from @Anoop-Malav is the same, just using pipenv to remove the virtual environment based on the current dir and reset it:

pipenv --rm
pipenv shell  # recreate a virtual env with your current Pipfile

MIME stands for Multi-purpose Internet Mail Extensions. MIME types form a standard way of classifying file types on the Internet. Internet programs such as Web servers and browsers all have a list of MIME types, so that they can transfer files of the same type in the same way, no matter what operating system they are working in.

A MIME type has two parts: a type and a subtype. They are separated by a slash (/). For example, the MIME type for Microsoft Word files is application and the subtype is msword. Together, the complete MIME type is application/msword.

Although there is a complete list of MIME types, it does not list the extensions associated with the files, nor a description of the file type. This means that if you want to find the MIME type for a certain kind of file, it can be difficult. Sometimes you have to look through the list and make a guess as to the MIME type of the file you are concerned with.

Update for Brian's answer:

If a function in Python 3 has keyword-only arguments, then you need to use inspect.getfullargspec:

def yay(a, b=10, *, c=20, d=30):
    pass
inspect.getfullargspec(yay)

yields this:

FullArgSpec(args=['a', 'b'], varargs=None, varkw=None, defaults=(10,), kwonlyargs=['c', 'd'], kwonlydefaults={'c': 20, 'd': 30}, annotations={})

As mantioned by Jon Rimmer, you can use GitExtensions. GitExtensions does work in Visual Studio 2005 and Visual Studio 2008, it also does work in Visual Studio 2010 if you manually copy and config the .Addin file.

In Java SE you need software to run the program like if you have developed a desktop application and if you want to share the application with other machines all the machines have to install the software for running the application. But in Java EE there is no software needed to install in all the machines. Java EE has the forward capabilities. This is only one simple example. There are lots of differences.

Your compiler just tried to compile the file named foo.cc. Upon hitting line number line, the compiler finds:

#include "bar"

or

#include <bar>

The compiler then tries to find that file. For this, it uses a set of directories to look into, but within this set, there is no file bar. For an explanation of the difference between the versions of the include statement look here.

How to tell the compiler where to find it

g++ has an option -I. It lets you add include search paths to the command line. Imagine that your file bar is in a folder named frobnicate, relative to foo.cc (assume you are compiling from the directory where foo.cc is located):

g++ -Ifrobnicate foo.cc

You can add more include-paths; each you give is relative to the current directory. Microsoft's compiler has a correlating option /I that works in the same way, or in Visual Studio, the folders can be set in the Property Pages of the Project, under Configuration Properties->C/C++->General->Additional Include Directories.

Now imagine you have multiple version of bar in different folders, given:

// A/bar
#include<string>
std::string which() { return "A/bar"; }

// B/bar
#include<string>
std::string which() { return "B/bar"; }

// C/bar
#include<string>
std::string which() { return "C/bar"; }

// foo.cc
#include "bar"
#include <iostream>

int main () {
    std::cout << which() << std::endl;
}

The priority with #include "bar" is leftmost:

$ g++ -IA -IB -IC foo.cc
$ ./a.out
A/bar

As you see, when the compiler started looking through A/, B/ and C/, it stopped at the first or leftmost hit.

This is true of both forms, include <> and incude "".

Difference between #include <bar> and #include "bar"

Usually, the #include <xxx> makes it look into system folders first, the #include "xxx" makes it look into the current or custom folders first.

E.g.:

Imagine you have the following files in your project folder:

list
main.cc

with main.cc:

#include "list"
....

For this, your compiler will #include the file list in your project folder, because it currently compiles main.cc and there is that file list in the current folder.

But with main.cc:

#include <list>
....

and then g++ main.cc, your compiler will look into the system folders first, and because <list> is a standard header, it will #include the file named list that comes with your C++ platform as part of the standard library.

This is all a bit simplified, but should give you the basic idea.

Details on <>/""-priorities and -I

According to the gcc-documentation, the priority for include <> is, on a "normal Unix system", as follows:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/c++/version, first. In the above, target is the canonical name of the system GCC was configured to compile code for; [...].

The documentation also states:

You can add to this list with the -Idir command line option. All the directories named by -I are searched, in left-to-right order, before the default directories. The only exception is when dir is already searched by default. In this case, the option is ignored and the search order for system directories remains unchanged.

To continue our #include<list> / #include"list" example (same code):

g++ -I. main.cc

and

#include<list>
int main () { std::list<int> l; }

and indeed, the -I. prioritizes the folder . over the system includes and we get a compiler error.

According to the spec

Dynamically modifying a source element and its attribute when the element is already inserted in a video or audio element will have no effect. To change what is playing, just use the src attribute on the media element directly, possibly making use of the canPlayType() method to pick from amongst available resources. Generally, manipulating source elements manually after the document has been parsed is an unncessarily complicated approach.

So what you are trying to do is apparently not supposed to work.

The csh shell has never been known for its extensive ability to manipulate file handles in the redirection process.

You can redirect both standard output and error to a file with:

xxx >& filename

but that's not quite what you were after, redirecting standard error to the current standard output.

However, if your underlying operating system exposes the standard output of a process in the file system (as Linux does with /dev/stdout), you can use that method as follows:

xxx >& /dev/stdout

This will force both standard output and standard error to go to the same place as the current standard output, effectively what you have with the bash redirection, 2>&1.

Just keep in mind this isn't a csh feature. If you run on an operating system that doesn't expose standard output as a file, you can't use this method.

However, there is another method. You can combine the two streams into one if you send it to a pipeline with |&, then all you need to do is find a pipeline component that writes its standard input to its standard output. In case you're unaware of such a thing, that's exactly what cat does if you don't give it any arguments. Hence, you can achieve your ends in this specific case with:

xxx |& cat

Of course, there's also nothing stopping you from running bash (assuming it's on the system somewhere) within a csh script to give you the added capabilities. Then you can use the rich redirections of that shell for the more complex cases where csh may struggle.

Let's explore this in more detail. First, create an executable echo_err that will write a string to stderr:

#include <stdio.h>
int main (int argc, char *argv[]) {
    fprintf (stderr, "stderr (%s)\n", (argc > 1) ? argv[1] : "?");
    return 0;
}

Then a control script test.csh which will show it in action:

#!/usr/bin/csh

ps -ef ; echo ; echo $$ ; echo

echo 'stdout (csh)'
./echo_err csh

bash -c "( echo 'stdout (bash)' ; ./echo_err bash ) 2>&1"

The echo of the PID and ps are simply so you can ensure it's csh running this script. When you run this script with:

./test.csh >test.out 2>test.err

(the initial redirection is set up by bash before csh starts running the script), and examine the out/err files, you see:

test.out:
    UID     PID    PPID  TTY        STIME     COMMAND
    pax    5708    5364  cons0      11:31:14  /usr/bin/ps
    pax    5364    7364  cons0      11:31:13  /usr/bin/tcsh
    pax    7364       1  cons0      10:44:30  /usr/bin/bash

    5364

    stdout (csh)
    stdout (bash)
    stderr (bash)

test.err:
    stderr (csh)

You can see there that the test.csh process is running in the C shell, and that calling bash from within there gives you the full bash power of redirection.

The 2>&1 in the bash command quite easily lets you redirect standard error to the current standard output (as desired) without prior knowledge of where standard output is currently going.

In my case, I wanted git to update to the latest and at the same time re-populate any missing files.

The following restored the missing files (thanks to --force which doesn't seem to have been mentioned here), but it didn't pull any new commits:

git submodule update --init --recursive --force

This did:

git submodule update --recursive --remote --merge --force

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

This worked for me.

header = ['row1', 'row2', 'row3']
some_list = [1, 2, 3]
with open('test.csv', 'wt', newline ='') as file:
    writer = csv.writer(file, delimiter=',')
    writer.writerow(i for i in header)
    for j in some_list:
        writer.writerow(j)

also.. try to "clean" your projects or solution and rebuild again!

I had the same problem and it turned out that parent service was a singelton. So the context automatically became singelton too. Even though was declared as Per Life Time Scoped in DI.

Injecting service with different lifetimes into another

1. Never inject Scoped & Transient services into Singleton service. ( This effectively converts the transient or scoped service into the singleton. )

2. Never inject Transient services into scoped service ( This converts the transient service into the scoped. )

These commands worked for Artik 10 :

• cat /etc/fedora-release
• cat /etc/issue
• hostnamectl

and these others didn't :

• lsb_release -a
• uname -a

Just subtract the string address from what strchr returns:

char *string = "qwerty";
char *e;
int index;

e = strchr(string, 'e');
index = (int)(e - string);

Note that the result is zero based, so in above example it will be 2.

SQL Injection can be done on any input the user can influence that isn't properly escaped before used in a query.

One example would be a get variable like this:

http//www.example.com/user.php?userid=5

Now, if the accompanying PHP code goes something like this:

$query = "SELECT username, password FROM users WHERE userid=" . $_GET['userid'];
// ...

You can easily use SQL injection here too:

http//www.example.com/user.php?userid=5 AND 1=2 UNION SELECT password,username FROM users WHERE usertype='admin'

(of course, the spaces will have to be replaced by %20, but this is more readable. Additionally, this is just an example making some more assumptions, but the idea should be clear.)

javafx.scene.Node class has a pair of methods setUserData(Object) and Object getUserData()

Which you could use to add your info to the Node.

So, you can call page.setUserData(info);

And controller can check, if info is set. Also, you could use ObjectProperty for back-forward data transfering, if needed.

Observe a documentation here: http://docs.oracle.com/javafx/2/api/javafx/fxml/doc-files/introduction_to_fxml.html Before the phrase "In the first version, the handleButtonAction() is tagged with @FXML to allow markup defined in the controller's document to invoke it. In the second example, the button field is annotated to allow the loader to set its value. The initialize() method is similarly annotated."

So, you need to associate a controller with a node, and set a user data to the node.

For Python 3:

ListOfStrings = []
ListOfStrings.append('foo')
ListOfStrings.append('oof')
for idx, item in enumerate(ListOfStrings):
if 'foo' in item:
    ListOfStrings[idx] = "bar"

Something like:

select t1.name, t2.image_id, t3.path
from table1 t1 inner join table2 t2 on t1.person_id = t2.person_id
inner join table3 t3 on t2.image_id=t3.image_id

It sounds like the application isn't signed. Download ldid from Cydia and then use it like so: ldid -S /Applications/AccelerometerGraph.app/AccelerometerGraph

Also be sure that the binary is marked as executable: chmod +x /Applications/AccelerometerGraph.app/AccelerometerGraph

Here is a case sensitive search that also separates your search into words to search in each model as well. Only when it finds a space will it try to split the query into an array and then search each word.

It returns true if every word is at least in one of the models.

$scope.songSearch = function (row) {
    var query = angular.lowercase($scope.query);
    if (query.indexOf(" ") > 0) {
        query_array = query.split(" ");
        search_result = false;
        for (x in query_array) {
            query = query_array[x];
            if (angular.lowercase(row.model1).indexOf(query || '') !== -1 || angular.lowercase(row.model2).indexOf(query || '') !== -1 || angular.lowercase(row.model3).indexOf(query || '') !== -1){
                search_result = true;
            } else {
                search_result = false;
                break;
            }
        }
        return search_result;
    } else {
        return (angular.lowercase(row.model1).indexOf(query || '') !== -1 || angular.lowercase(row.model2).indexOf(query || '') !== -1 || angular.lowercase(row.model3).indexOf(query || '') !== -1);
    }
};

This frustrated the heck out of me, and none of the above answers really got me what I wanted. I finally found the answer I was looking for, on a mac if you do ? + option + F it will bring up a Find-Replace bar at the bottom of your editor which is local to the file you have open.

There is an icon option which when hovered over says "In Selection" that you can select to find and replace within a selection. I've pointed to the correct icon in the screenshot below.

Hit replace all, and voila, all instances of '0' will be replaced with '255'.

Note: this feature is ONLY available when you use ? + option + F.

It does NOT appear when you use ? + shift + F.

Note: this will replace all instances of '0' with '255'. If you wanted to replace 0 (without the quotes) with 255, then just put 0 (without quotes) and 255 in the Find What: and Replace With: fields respectively.

Note:

option key is also labeled as the alt key.

? key is also labeled as the command key.

That is pretty much the same as created a normal website.

Normal pattern for a php website is:

1. The user enter a url
2. The server get the url, parse it and execute a action
3. In this action, you get/generate every information you need for the page
4. You create the html/php page with the info from the action
5. The server generate a fully html page and send it back to the user

With a api, you just add a new step between 3 and 4. After 3, create a array with all information you need. Encode this array in json and exit or return this value.

$info = array("info_1" => 1; "info_2" => "info_2" ... "info_n" => array(1,2,3));
exit(json_encode($info));

That all for the api. For the client side, you can call the api by the url. If the api work only with get call, I think it's possible to do a simply (To check, I normally use curl).

$info = file_get_contents(url);
$info = json_decode($info);

But it's more common to use the curl library to perform get and post call. You can ask me if you need help with curl.

Once the get the info from the api, you can do the 4 & 5 steps.

Look the php doc for json function and file_get_contents.

curl : http://fr.php.net/manual/fr/ref.curl.php

EDIT

No, wait, I don't get it. "php API page" what do you mean by that ?

The api is only the creation/recuperation of your project. You NEVER send directly the html result (if you're making a website) throw a api. You call the api with the url, the api return information, you use this information to create the final result.

ex: you want to write a html page who say hello xxx. But to get the name of the user, you have to get the info from the api.

So let's say your api have a function who have user_id as argument and return the name of this user (let's say getUserNameById(user_id)), and you call this function only on a url like your/api/ulr/getUser/id.

Function getUserNameById(user_id)
{
  $userName = // call in db to get the user
  exit(json_encode($userName)); // maybe return work as well.
}

From the client side you do

    $username = file_get_contents(your/api/url/getUser/15); // You should normally use curl, but it simpler for the example
// So this function to this specifique url will call the api, and trigger the getUserNameById(user_id), whom give you the user name.
    <html>
    <body>
    <p>hello <?php echo $username ?> </p>
    </body>
    </html>

So the client never access directly the databases, that the api's role.

Is that clearer ?

After Change your Function or Code Follow these two steps.

First Enable CORS Then Deploy API every time.

You can also replace "-moz-user-select:none" with "-moz-user-select:inherit". This will inherit the style value from any parent style or from the default style if no parent style was defined.

The tutorial you saw was telling you how to exit nano editor. By typing Ctrl+X nano exits and if your file needs change you will be prompted to save the changes in which case to save you should press Y and then enter to save changes in the same file you open.

If you are not using any gui and you just want to leave the shell the command is Ctrl+D.

Regarding tutorial, The Linux Documentation Project would be a good place to start. If you like books I would recommend by far any book you want from O'Reilly. They have nice cd bookshelfs with good compilation for any linux sysadmin, and without much effort you can find many places where those html bookshelfs are available to read online.

This typed error-message also shows while an if-statement comparison is done where there is an array and for example a bool or int. See for example:

... code snippet ...

if dataset == bool:
    ....

... code snippet ...

This clause has dataset as array and bool is euhm the "open door"... True or False.

In case the function is wrapped within a try-statement you will receive with except Exception as error: the message without its error-type:

The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

Have you looked at any of the Maven docs, for example, the maven install plugin docs?

Nutshell version: it will build the project and install it in your local repository.

You can make your div HTML code and set it directly into body(Or any element) with following code:

var divStr = '<div class="text-warning">Some html</div>';
document.getElementsByTagName('body')[0].innerHTML += divStr;

If your goal is to keep a local copy of the repository for easy backup or for sticking onto an external drive or sharing via cloud storage (Dropbox, etc) you may want to use a bare repository. This allows you to create a copy of the repository without a working directory, optimized for sharing.

For example:

$ git init --bare ~/repos/myproject.git
$ cd /path/to/existing/repo
$ git remote add origin ~/repos/myproject.git
$ git push origin master

Similarly you can clone as if this were a remote repo:

$ git clone ~/repos/myproject.git

You're nearly there!

For a bold text, you should have this: <b> bold text</b> or <strong>bold text</strong> They have the same result.

Lets say you have an global array declared at the top of the page

int global[] = { 1, 2, 3, 4 };

To find out how many elements are there (in c++) in the array type the following code:

sizeof(global) / 4;

The sizeof(NAME_OF_ARRAY) / 4 will give you back the number of elements for the given array name.

If you are in the iframe context,

you could do

const currentIframeHref = new URL(document.location.href);
const urlOrigin = currentIframeHref.origin;
const urlFilePath = decodeURIComponent(currentIframeHref.pathname);

If you are in the parent window/frame, then you can use https://stackoverflow.com/a/938195/2305243 's answer, which is

document.getElementById("iframe_id").contentWindow.location.href

Just use .empty():

// snip...
}).done(function (data) {
    // Clear drop down list
    $(dropdown).empty(); // <<<<<< No more issue here
    // Fill drop down list with new data
    $(data).each(function () {
        // snip...

There's also a more concise way to build up the options:

// snip...
$(data).each(function () {
    $("<option />", {
        val: this.value,
        text: this.text
    }).appendTo(dropdown);
});

You can catch it like any other exception:

try {
  foo();
}
catch (const std::bad_alloc&) {
  return -1;
}

Quite what you can usefully do from this point is up to you, but it's definitely feasible technically.

In general you cannot, and should not try, to respond to this error. bad_alloc indicates that a resource cannot be allocated because not enough memory is available. In most scenarios your program cannot hope to cope with that, and terminating soon is the only meaningful behaviour.

Worse, modern operating systems often over-allocate: on such systems, malloc and new can return a valid pointer even if there is not enough free memory left – std::bad_alloc will never be thrown, or is at least not a reliable sign of memory exhaustion. Instead, attempts to access the allocated memory will then result in a segmentation fault, which is not catchable (you can handle the segmentation fault signal, but you cannot resume the program afterwards).

The only thing you could do when catching std::bad_alloc is to perhaps log the error, and try to ensure a safe program termination by freeing outstanding resources (but this is done automatically in the normal course of stack unwinding after the error gets thrown if the program uses RAII appropriately).

In certain cases, the program may attempt to free some memory and try again, or use secondary memory (= disk) instead of RAM but these opportunities only exist in very specific scenarios with strict conditions:

1. The application must ensure that it runs on a system that does not overcommit memory, i.e. it signals failure upon allocation rather than later.
2. The application must be able to free memory immediately, without any further accidental allocations in the meantime.

It’s exceedingly rare that applications have control over point 1 — userspace applications never do, it’s a system-wide setting that requires root permissions to change.¹

OK, so let’s assume you’ve fixed point 1. What you can now do is for instance use a LRU cache for some of your data (probably some particularly large business objects that can be regenerated or reloaded on demand). Next, you need to put the actual logic that may fail into a function that supports retry — in other words, if it gets aborted, you can just relaunch it:

lru_cache<widget> widget_cache;

double perform_operation(int widget_id) {
    std::optional<widget> maybe_widget = widget_cache.find_by_id(widget_id);
    if (not maybe_widget) {
        maybe_widget = widget_cache.store(widget_id, load_widget_from_disk(widget_id));
    }
    return maybe_widget->frobnicate();
}

…

for (int num_attempts = 0; num_attempts < MAX_NUM_ATTEMPTS; ++num_attempts) {
    try {
        return perform_operation(widget_id);
    } catch (std::bad_alloc const&) {
        if (widget_cache.empty()) throw; // memory error elsewhere.
        widget_cache.remove_oldest();
    }
}

// Handle too many failed attempts here.

But even here, using std::set_new_handler instead of handling std::bad_alloc provides the same benefit and would be much simpler.

¹ If you’re creating an application that does control point 1, and you’re reading this answer, please shoot me an email, I’m genuinely curious about your circumstances.

What is the C++ Standard specified behavior of new in c++?

The usual notion is that if new operator cannot allocate dynamic memory of the requested size, then it should throw an exception of type std::bad_alloc.
However, something more happens even before a bad_alloc exception is thrown:

C++03 Section 3.7.4.1.3: says

An allocation function that fails to allocate storage can invoke the currently installed new_handler(18.4.2.2), if any. [Note: A program-supplied allocation function can obtain the address of the currently installed new_handler using the set_new_handler function (18.4.2.3).] If an allocation function declared with an empty exception-specification (15.4), throw(), fails to allocate storage, it shall return a null pointer. Any other allocation function that fails to allocate storage shall only indicate failure by throw-ing an exception of class std::bad_alloc (18.4.2.1) or a class derived from std::bad_alloc.

Consider the following code sample:

#include <iostream>
#include <cstdlib>

// function to call if operator new can't allocate enough memory or error arises
void outOfMemHandler()
{
    std::cerr << "Unable to satisfy request for memory\n";

    std::abort();
}

int main()
{
    //set the new_handler
    std::set_new_handler(outOfMemHandler);

    //Request huge memory size, that will cause ::operator new to fail
    int *pBigDataArray = new int[100000000L];

    return 0;
}

In the above example, operator new (most likely) will be unable to allocate space for 100,000,000 integers, and the function outOfMemHandler() will be called, and the program will abort after issuing an error message.

As seen here the default behavior of new operator when unable to fulfill a memory request, is to call the new-handler function repeatedly until it can find enough memory or there is no more new handlers. In the above example, unless we call std::abort(), outOfMemHandler() would be called repeatedly. Therefore, the handler should either ensure that the next allocation succeeds, or register another handler, or register no handler, or not return (i.e. terminate the program). If there is no new handler and the allocation fails, the operator will throw an exception.

What is the new_handler and set_new_handler?

new_handler is a typedef for a pointer to a function that takes and returns nothing, and set_new_handler is a function that takes and returns a new_handler.

Something like:

typedef void (*new_handler)();
new_handler set_new_handler(new_handler p) throw();

set_new_handler's parameter is a pointer to the function operator new should call if it can't allocate the requested memory. Its return value is a pointer to the previously registered handler function, or null if there was no previous handler.

How to handle out of memory conditions in C++?

Given the behavior of newa well designed user program should handle out of memory conditions by providing a proper new_handlerwhich does one of the following:

Make more memory available: This may allow the next memory allocation attempt inside operator new's loop to succeed. One way to implement this is to allocate a large block of memory at program start-up, then release it for use in the program the first time the new-handler is invoked.

Install a different new-handler: If the current new-handler can't make any more memory available, and of there is another new-handler that can, then the current new-handler can install the other new-handler in its place (by calling set_new_handler). The next time operator new calls the new-handler function, it will get the one most recently installed.

(A variation on this theme is for a new-handler to modify its own behavior, so the next time it's invoked, it does something different. One way to achieve this is to have the new-handler modify static, namespace-specific, or global data that affects the new-handler's behavior.)

Uninstall the new-handler: This is done by passing a null pointer to set_new_handler. With no new-handler installed, operator new will throw an exception ((convertible to) std::bad_alloc) when memory allocation is unsuccessful.

Throw an exception convertible to std::bad_alloc. Such exceptions are not be caught by operator new, but will propagate to the site originating the request for memory.

Not return: By calling abort or exit.

In Oracle, This work for me

SELECT name, min(date), min(time)
    FROM table_name
GROUP BY name

If the strings are the same length, then I would go for '%x' % () of the built-in xor (^).

Examples -

>>>a = '290b6e3a'
>>>b = 'd6f491c5'
>>>'%x' % (int(a,16)^int(b,16))
'ffffffff'
>>>c = 'abcd'
>>>d = '12ef'
>>>'%x' % (int(a,16)^int(b,16))
'b922'

If the strings are not the same length, truncate the longer string to the length of the shorter using a slice longer = longer[:len(shorter)]

Check that the connection string is in your Web.Config. I removed that node and put it in my Web.Debug.config and this is the error I received. Moved it back to the Web.config and worked great.

It seems that the only parameter that allows you to inject custom text is the "quote".

INNER JOIN = JOIN

INNER JOIN is the default if you don't specify the type when you use the word JOIN.

You can also use LEFT OUTER JOIN or RIGHT OUTER JOIN, in which case the word OUTER is optional, or you can specify CROSS JOIN.

OR

For an inner join, the syntax is:

SELECT ...
FROM TableA
[INNER] JOIN TableB

(in other words, the "INNER" keyword is optional - results are the same with or without it)

Try cleaning your hosts file.

I spent about half a day on this, and none of these answers worked for me. I finally found the solution hinted at on OTN (the last place I look when I run into Oracle issues), and someone mentioned looking at the hosts file. I had recently modified the hosts file because this particular machine didn't have access to DNS.

I had a line for this host:

123.123.123.123     fully.qualified.domain.name.com     hostname

Commenting out the line above allowed me to install the Oracle client.

Somewhat similar to your original attempt, but more Pythonic, is to use Python's standard negative-indexing convention to count backwards from the end:

df[df.columns[-1]]

From MySQL 8.0 you could use

ALTER TABLE table_name RENAME COLUMN old_col_name TO new_col_name;

ALTER TABLE Syntax:

RENAME COLUMN:

• Can change a column name but not its definition.

• More convenient than CHANGE to rename a column without changing its definition.

DBFiddle Demo

Try something like this

var d = new Date,
    dformat = [d.getMonth()+1,
               d.getDate(),
               d.getFullYear()].join('/')+' '+
              [d.getHours(),
               d.getMinutes(),
               d.getSeconds()].join(':');

If you want leading zero's for values < 10, use this number extension

Number.prototype.padLeft = function(base,chr){
    var  len = (String(base || 10).length - String(this).length)+1;
    return len > 0? new Array(len).join(chr || '0')+this : this;
}
// usage
//=> 3..padLeft() => '03'
//=> 3..padLeft(100,'-') => '--3' 

Applied to the previous code:

var d = new Date,
    dformat = [(d.getMonth()+1).padLeft(),
               d.getDate().padLeft(),
               d.getFullYear()].join('/') +' ' +
              [d.getHours().padLeft(),
               d.getMinutes().padLeft(),
               d.getSeconds().padLeft()].join(':');
//=> dformat => '05/17/2012 10:52:21'

See this code in jsfiddle

[edit 2019] Using ES20xx, you can use a template literal and the new padStart string extension.

var dt = new Date();_x000D_
_x000D_
console.log(`${_x000D_
    (dt.getMonth()+1).toString().padStart(2, '0')}/${_x000D_
    dt.getDate().toString().padStart(2, '0')}/${_x000D_
    dt.getFullYear().toString().padStart(4, '0')} ${_x000D_
    dt.getHours().toString().padStart(2, '0')}:${_x000D_
    dt.getMinutes().toString().padStart(2, '0')}:${_x000D_
    dt.getSeconds().toString().padStart(2, '0')}`_x000D_

Brother you don't need to set class path just follow these simple steps (I use Apache NetBeans)

Steps:

1. extract the jar file which you want to add in your project.

2. only copy those packages (folder) which you need in the project. (do not copy manifest file)

3. open the main project jar file(dist/file.jar) with WinRAR.

4. paste that folder or package in the main project jar file.

5. Those packages work 100% in your project.

warning: Do not make any changes in the manifest file.

Another method:

• In my case lib folder present outside the dist(main jar file) folder.

• we need to move lib folder in dist folder.then we set class path from manifest.mf file of main jar file.

  Edit the manifest.mf And ADD this type of line

• Class-Path: lib\foldername\jarfilename.jar lib\foldername\jarfilename.jar

Warning: lib folder must be inside the dist folder otherwise jar file do not access your lib folder jar files

The simplest way to modify all files of a project at once (batch) is through Line Endings Unify package:

1. Ctrl+Shift+P type inst + choose Install Package.
2. Type line end + choose Line Endings Unify.
3. Once installed, Ctrl+Shift+P + type end + choose Line Endings Unify.

4. OR (instead of 3.) copy:

   {
    "keys": ["ctrl+alt+l"],
    "command": "line_endings_unify"
   },
   

   to the User array (right pane, after the opening [) in Preferences -> KeyBindings + press Ctrl+Alt+L.

As mentioned in another answer:

• The Carriage Return (CR) character (0x0D, \r) [...] Early Macintosh operating systems (OS-9 and earlier).

• The Line Feed (LF) character (0x0A, \n) [...] UNIX based systems (Linux, Mac OSX)

• The End of Line (EOL) sequence (0x0D 0x0A, \r\n) [...] (non-Unix: Windows, Symbian OS).

If you have node_modules, build or other auto-generated folders, delete them before running the package.

When you run the package:

1. you are asked at the bottom to choose which file extensions to search through a comma separated list (type the only ones you need to speed up the replacements, e.g. js,jsx).
2. then you are asked which Input line ending to use, e.g. if you need LF type \n.
3. press ENTER and wait until you see an alert window with LineEndingsUnify Complete.

As a supplement to above answers - I'm just bumping into a similar problem, and working completely of the default installed python.

When I call the example of the shared object library I'm looking for with LD_LIBRARY_PATH, I get something like this:

$ LD_LIBRARY_PATH=/path/to/mysodir:$LD_LIBRARY_PATH python example-so-user.py
python: can't open file 'example-so-user.py': [Errno 2] No such file or directory

Notably, it doesn't even complain about the import - it complains about the source file!

But if I force loading of the object using LD_PRELOAD:

$ LD_PRELOAD=/path/to/mysodir/mypyobj.so python example-so-user.py
python: error while loading shared libraries: libtiff.so.5: cannot open shared object file: No such file or directory

... I immediately get a more meaningful error message - about a missing dependency!

Just thought I'd jot this down here - cheers!

I solved my own problem when using google distance matrix API by setting my request header with Jquery ajax. take a look below.

          }
      }

      $.ajax(settings).done(function (response) {
          console.log(response);

I hope this helps.

Instead of typedef struct { ... } pos; you should be doing struct pos { ... };. The issue here is that you are using the pos type name before it is defined. By moving the name to the top of the struct definition, you are able to use that name within the struct definition itself.

Further, the typedef struct { ... } name; pattern is a C-ism, and doesn't have much place in C++.

To answer your question about inline, there is no difference in this case. When a method is defined within the struct/class definition, it is implicitly declared inline. When you explicitly specify inline, the compiler effectively ignores it because the method is already declared inline.

(inline methods will not trigger a linker error if the same method is defined in multiple object files; the linker will simply ignore all but one of them, assuming that they are all the same implementation. This is the only guaranteed change in behavior with inline methods. Nowadays, they do not affect the compiler's decision regarding whether or not to inline functions; they simply facilitate making the function implementation available in all translation units, which gives the compiler the option to inline the function, if it decides it would be beneficial to do so.)

This is excellent practice.

By creating variables inside loops, you ensure their scope is restricted to inside the loop. It cannot be referenced nor called outside of the loop.

This way:

• If the name of the variable is a bit "generic" (like "i"), there is no risk to mix it with another variable of same name somewhere later in your code (can also be mitigated using the -Wshadow warning instruction on GCC)

• The compiler knows that the variable scope is limited to inside the loop, and therefore will issue a proper error message if the variable is by mistake referenced elsewhere.

• Last but not least, some dedicated optimization can be performed more efficiently by the compiler (most importantly register allocation), since it knows that the variable cannot be used outside of the loop. For example, no need to store the result for later re-use.

In short, you are right to do it.

Note however that the variable is not supposed to retain its value between each loop. In such case, you may need to initialize it every time. You can also create a larger block, encompassing the loop, whose sole purpose is to declare variables which must retain their value from one loop to another. This typically includes the loop counter itself.

{
    int i, retainValue;
    for (i=0; i<N; i++)
    {
       int tmpValue;
       /* tmpValue is uninitialized */
       /* retainValue still has its previous value from previous loop */

       /* Do some stuff here */
    }
    /* Here, retainValue is still valid; tmpValue no longer */
}

For question #2: The variable is allocated once, when the function is called. In fact, from an allocation perspective, it is (nearly) the same as declaring the variable at the beginning of the function. The only difference is the scope: the variable cannot be used outside of the loop. It may even be possible that the variable is not allocated, just re-using some free slot (from other variable whose scope has ended).

With restricted and more precise scope come more accurate optimizations. But more importantly, it makes your code safer, with less states (i.e. variables) to worry about when reading other parts of the code.

This is true even outside of an if(){...} block. Typically, instead of :

    int result;
    (...)
    result = f1();
    if (result) then { (...) }
    (...)
    result = f2();
    if (result) then { (...) }

it's safer to write :

    (...)
    {
        int const result = f1();
        if (result) then { (...) }
    }
    (...)
    {
        int const result = f2();
        if (result) then { (...) }
    }

The difference may seem minor, especially on such a small example. But on a larger code base, it will help : now there is no risk to transport some result value from f1() to f2() block. Each result is strictly limited to its own scope, making its role more accurate. From a reviewer perspective, it's much nicer, since he has less long range state variables to worry about and track.

Even the compiler will help better : assuming that, in the future, after some erroneous change of code, result is not properly initialized with f2(). The second version will simply refuse to work, stating a clear error message at compile time (way better than run time). The first version will not spot anything, the result of f1() will simply be tested a second time, being confused for the result of f2().

Complementary information

The open-source tool CppCheck (a static analysis tool for C/C++ code) provides some excellent hints regarding optimal scope of variables.

In response to comment on allocation: The above rule is true in C, but might not be for some C++ classes.

For standard types and structures, the size of variable is known at compilation time. There is no such thing as "construction" in C, so the space for the variable will simply be allocated into the stack (without any initialization), when the function is called. That's why there is a "zero" cost when declaring the variable inside a loop.

However, for C++ classes, there is this constructor thing which I know much less about. I guess allocation is probably not going to be the issue, since the compiler shall be clever enough to reuse the same space, but the initialization is likely to take place at each loop iteration.

$final_array = array_combine($a, $a);

Reference: http://php.net/array-combine

P.S. Be careful with source array containing duplicated keys like the following:

$a = ['one','two','one'];

Note the duplicated one element.

You could define a function using model_to_dict as follows:

def queryset_to_list(qs,fields=None, exclude=None):
    my_list=[]
    for x in qs:
        my_list.append(model_to_dict(x,fields=fields,exclude=exclude))
    return my_list

Suppose your Model has following fields

id
name
email

Run following commands in django shell

>>>qs=<yourmodel>.objects.all()
>>>list=queryset_to_dict(qs)
>>>list
[{'id':1, 'name':'abc', 'email':'[email protected]'},{'id':2, 'name':'xyz', 'email':'[email protected]'}]

Say you want only id and name in the list of queryset dictionary

>>>qs=<yourmodel>.objects.all()
>>>list=queryset_to_dict(qs,fields=['id','name'])
>>>list
[{'id':1, 'name':'abc'},{'id':2, 'name':'xyz'}]

Similarly you can exclude fields in your output.

print every line, like use Java BufferedReader read ervery line, and print it:

scala.io.Source.fromFile("test.txt" ).foreach{  print  }

equivalent:

scala.io.Source.fromFile("test.txt" ).foreach( x => print(x))

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

If your Object contains Objects then check if they are null, if it have primitives check for their default values.

for Instance:

Person Object 
name Property with getter and setter

to check if name is not initialized. 

Person p = new Person();
if(p.getName()!=null)

This is what I use to get the minimum date in SQL Server. Please note that it is globalisation friendly:

CREATE FUNCTION [dbo].[DateTimeMinValue]()
RETURNS datetime
AS
BEGIN
  RETURN (SELECT
    CAST('17530101' AS datetime))
END

Call using:

SELECT [dbo].[DateTimeMinValue]()

It's not a single operator, it's two. It's equivalent to the following and is a quick way to cast a value to boolean.

val.enabled = !(!enable);

Cmdlets in powershell accept a bunch of arguments. When these arguments are defined you can define a position for each of them.

This allows you to call a cmdlet without specifying the parameter name. So for the following cmdlet the path attribute is define with a position of 0 allowing you to skip typing -Path when invoking it and as such both the following will work.

Get-Item -Path C:\temp\thing.txt
Get-Item C:\temp\thing.txt

However if you specify more arguments than there are positional parameters defined then you will get the error.

Get-Item C:\temp\thing.txt "*"

As this cmdlet does not know how to accept the second positional parameter you get the error. You can fix this by telling it what the parameter is meant to be.

Get-Item C:\temp\thing.txt -Filter "*"

I assume you are getting the error on the following line of code as it seems to be the only place you are not specifying the parameter names correctly, and maybe it is treating the = as a parameter and $username as another parameter.

Set-ADUser $user -userPrincipalName = $newname

Try specifying the parameter name for $user and removing the =

So the bad news is that XCode is needed for its iOS Simulator as well as its Application Loader facility for actually uploading the programs to iOS devices for "real" testing. You'll need XCode for signing your apps before submitting to the App Store. Unfortunately, XCode is only available for OS X.

However, the good news is that you may be able to purchase OS X and run it in a virtual machine such as VMWare Workstation. I don't know how straightforward this is, as it is rather difficult to get OS X to run on non-Apple hardware, but a quick Google search shows that it is possible. This method would (likely) be cheaper than purchasing a new Mac, although the Mac Mini retails in the US for only $599. Some posts I've seen indicate that this may or may not be legal, others say you need OS X Server for virtualization. I'll leave the research up to you.

There are also services such as MacInCloud that allow you to rent a Mac server that you can access from Windows via remote desktop, or through your browser. Unfortunately, I don't think you'd be able to use Application Loader, as you have to physically connect the device to your computer, but it would work for development and simulation, at least.

Good luck!

Recently I am working with the 1.8.0_25 JDK version on Windows 8.1 and I had the same problem with this. But as PankaJ Jakhar said

The real solution for me was pretty simple:

1. Add the JAVA_HOME variable to the system ones, not on the user ones.

2. The path I introduced for this variable was:

   C:\Program Files\Java\jdk1.8.0_25\
   

And it works for me!

create directory in /res/anim and create bottom_to_original.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="1500"
        android:fromYDelta="100%"
        android:toYDelta="1%" />
</set>

JAVA:

    LinearLayout ll = findViewById(R.id.ll);

    Animation animation;
    animation = AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.sample_animation);
    ll .setAnimation(animation);

What you need is named array. I wanted to write the following code:

int[] n = new int[4];

for(int i=1;i<4;i++)
{
    n[i] = 5;
}

I have the same issue in my asp.net web application. I solved by this link

I just replace ' with ’ text like below and my site in browser show apostrophe without rectangle around as in question ask.

I use the following to detect different mobile devices, viewport and screen. Works quite well for me, might be helpful to others:

var pixelRatio = window.devicePixelRatio || 1;

var viewport = {
    width: window.innerWidth,
    height: window.innerHeight
};

var screen = {
    width: window.screen.availWidth * pixelRatio,
    height: window.screen.availHeight * pixelRatio
};

var iPhone = /iPhone/i.test(navigator.userAgent);
var iPhone4 = (iPhone && pixelRatio == 2);
var iPhone5 = /iPhone OS 5_0/i.test(navigator.userAgent);
var iPad = /iPad/i.test(navigator.userAgent);
var android = /android/i.test(navigator.userAgent);
var webos = /hpwos/i.test(navigator.userAgent);
var iOS = iPhone || iPad;
var mobile = iOS || android || webos;

window.devicePixelRatio is the ratio between physical pixels and device-independent pixels (dips) on the device. window.devicePixelRatio = physical pixels / dips.

I think you want an additional projection that maps each group to a sorted-version of the group:

.Select(group => group.OrderByDescending(student => student.Grade))

It also appears like you might want another flattening operation after that which will give you a sequence of students instead of a sequence of groups:

.SelectMany(group => group)

You can always collapse both into a single SelectMany call that does the projection and flattening together.

EDIT: As Jon Skeet points out, there are certain inefficiencies in the overall query; the information gained from sorting each group is not being used in the ordering of the groups themselves. By moving the sorting of each group to come before the ordering of the groups themselves, the Max query can be dodged into a simpler First query.

• Unfold all – Ctrl+M, Ctrl+L
• Stop outlining – Ctrl+M, Ctrl+P
• Fold all – Ctrl+M, Ctrl+O

What you're looking for is called a "reverse merge". You should consult the docs regarding the merge function in the SVN book (as luapyad, or more precisely the first commenter on that post, points out). If you're using Tortoise, you can also just go into the log view and right-click and choose "revert changes from this revision" on the one where you made the mistake.

If you just want the last date for each account, you'd use this:

var q = from n in table
        group n by n.AccountId into g
        select new {AccountId = g.Key, Date = g.Max(t=>t.Date)};

If you want the whole record:

var q = from n in table
        group n by n.AccountId into g
        select g.OrderByDescending(t=>t.Date).FirstOrDefault();

In addition, you can use it to check if the dynamic allocation was successful.

Code example:

int ** p;
p = new int * [5];      // Dynamic array (size 5) of pointers to int
for (int i = 0; i < 5; ++i) {
    p[i] = new int[3]; // Each i(ptr) is now pointing to a dynamic
                       // array (size 3) of actual int values
}

assert (p);            // Check the dynamic allocation.

Similar to:

if (p == NULL) {
    cout << "dynamic allocation failed" << endl;
    exit(1);
}

Assuming your code above is the actual code, you have two problems:

1) your if statements need to be '==', not '='. You want to do comparison, not assignment.

2) The second if should be an 'else if'. Otherwise when it's false, you will set it to true, then the second if will be evaluated, and you'll set it back to false, as you describe

if (a == false) {
  a = true;
} else if (a == true) {
  a = false;
}

Another thing that would make it even simpler is the '!' operator:

a = !a;

will switch the value of a.

In case you want to check if multiple env variables are not set, you can do the following:

import os

MANDATORY_ENV_VARS = ["FOO", "BAR"]

for var in MANDATORY_ENV_VARS:
    if var not in os.environ:
        raise EnvironmentError("Failed because {} is not set.".format(var))

The standard associative-container erase idiom:

for (auto it = m.cbegin(); it != m.cend() /* not hoisted */; /* no increment */)
{
  if (must_delete)
  {
    m.erase(it++);    // or "it = m.erase(it)" since C++11
  }
  else
  {
    ++it;
  }
}

Note that we really want an ordinary for loop here, since we are modifying the container itself. The range-based loop should be strictly reserved for situations where we only care about the elements. The syntax for the RBFL makes this clear by not even exposing the container inside the loop body.

Edit. Pre-C++11, you could not erase const-iterators. There you would have to say:

for (std::map<K,V>::iterator it = m.begin(); it != m.end(); ) { /* ... */ }

Erasing an element from a container is not at odds with constness of the element. By analogy, it has always been perfectly legitimate to delete p where p is a pointer-to-constant. Constness does not constrain lifetime; const values in C++ can still stop existing.

1. Add your JDK's /bin folder to the PATH environmental variable. You can do this under System settings > Environmental variables, or via CLI:

   set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
   

2. Close and reopen your CLI window

I had a similar problem. I have a class;

Action<T>

which has a property of type T.

How do I get the property when I don't know T? I can't cast to Action<> unless I know T.

SOLUTION:

Implement a non-generic interface;

public interface IGetGenericTypeInstance
{
    object GenericTypeInstance();
}

Now I can cast the object to IGetGenericTypeInstance and GenericTypeInstance will return the property as type object.

There is a simple solution with splice. According to W3School splice syntax is following;

array.splice(index, howmany, item1, ....., itemX)

index Required. An integer that specifies at what position to add/remove items, Use negative values to specify the position from the end of the array

howmany Required. The number of items to be removed. If set to 0, no items will be removed

item1, ..., itemX Optional. The new item(s) to be added to the array

Keep that in mind, the following js will pop one or more matched item from the given array if found, otherwise wouldn't remove the last item of the array.

var x = [1,2,3,4,5,4,4,6,7];
var item = 4;
var startItemIndex = $.inArray(item, x);
var itemsFound = x.filter(function(elem){
                            return elem == item;
                          }).length;

Or

var itemsFound = $.grep(x, function (elem) {
                              return elem == item;
                           }).length;

So the final should look like the following

x.splice( startItemIndex , itemsFound );

Hope this helps.

Here's the link that gives me the answer and we use gmail:

Install the "fake sendmail for windows". If you are not using XAMPP you can download it here: http://glob.com.au/sendmail/sendmail.zip

Modify the php.ini file to use it (commented out the other lines):

mail function

For Win32 only.

SMTP = smtp.gmail.com
smtp_port = 25
For Win32 only.
sendmail_from = <e-mail username>@gmail.com

For Unix only.

You may supply arguments as well (default: sendmail -t -i).

sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(ignore the "Unix only" bit, since we actually are using sendmail)

You then have to configure the "sendmail.ini" file in the directory where sendmail was installed:

sendmail

smtp_server=smtp.gmail.com
smtp_port=25
error_logfile=error.log
debug_logfile=debug.log
auth_username=<username>
auth_password=<password>
force_sender=<e-mail username>@gmail.com

You can try fxCanvas: https://code.google.com/p/fxcanvas/

It implements almost all Canvas API within flash shim.

Choose either:

a) Create not null with some valid default value
b) Create null, fill it, alter to not null

For the replacement string and the replacement pattern as specified by $. here a resume:

link to doc : here

"hello _there_".replace(/_(.*?)_/g, "<div>$1</div>")

Note:

If you want to have a $ in the replacement string use $$. Same as with vscode snippet system.

Try this:

Function UserNameWindows() As String
     UserName = Environ("USERNAME")
End Function

This may help you.

1. Right click on git bash -> properties
2. In Shorcut tab -> Start in field -> enter your user defined path
3. Make sure the Target field does not include --go-to-home or it will continue to start in the directory specified in your HOME variable

Thats it.

Assert statements are a convenient way to insert debugging assertions into a program

I don't like any of the other answers. The ActivityManager is not meant to be used for getting the current activity. Super classing and depending on onDestroy is also fragile and not the best design.

Honestly, the best I have came up with so far is just maintaining an enum in my Application, which gets set when an activity is created.

Another recommendation might be to just shy away from using multiple activities if possible. This can be done either with using fragments, or in my preference custom views.

You can try removing the width and height attributes on the svg root element, adding preserveAspectRatio="none" viewBox="0 0 1024 800" instead. It makes a difference in Opera at least, assuming you wanted the svg to stretch to fill the entire region defined by the CSS styles.

Since 2019, Array.prototype.flatMap is good option.

options.flatMap(o => o.assigned ? [o.name] : []);

From the MDN page linked above:

flatMap can be used as a way to add and remove items (modify the number of items) during a map. In other words, it allows you to map many items to many items (by handling each input item separately), rather than always one-to-one. In this sense, it works like the opposite of filter. Simply return a 1-element array to keep the item, a multiple-element array to add items, or a 0-element array to remove the item.

pass the output to str() function and it will remove the convert the unicode output. also by printing the output it will remove the u'' tags from it.

style="table-layout:fixed; width:98%; word-wrap:break-word"

This worked great for me. I had long links that would cause the table to exceed 100% on web browsers. Tested on IE, Chrome, Android and Safari.

I have read all answers, but this link was more clear explanation for me about difference between CPU(Processor) and Core. So I'm leaving here some notes from there.

The main difference between CPU and Core is that the CPU is an electronic circuit inside the computer that carries out instruction to perform arithmetic, logical, control and input/output operations while the core is an execution unit inside the CPU that receives and executes instructions.

It may be a background image on the body. Check this link for more informations : http://drupal.org/node/1323608

While the proposed solutions work, I was trying to implement with Full Calendar and it would require over 90 database calls for each view (as it loads current, previous, and next month), which, I wasn't too thrilled about.

I found an recursion library https://github.com/tplaner/When where you simply store the rules in the database and one query to pull all the relevant rules.

Hopefully this will help someone else, as I spent so many hours trying to find a good solution.

Edit: This Library is for PHP

You can use this or refer further this https://select2.org/programmatic-control/add-select-clear-items

$('#mySelect2').val(null).trigger('change');

In my case, I created a new project and when I ran it the first time, it gave me the following error:

An unhandled exception was generated during the execution of the current web request. Information regarding the origin and location of the exception can be identified using the exception stack trace below.

So my solution was to go to the Package Manager Console inside the Visual Studio and run:Update-Package

Problem solved!!

There is a comprehensive doc for google calendar and other calendar services: https://github.com/InteractionDesignFoundation/add-event-to-calendar-docs/blob/master/services/google.md

An example of working link: https://calendar.google.com/calendar/render?action=TEMPLATE&text=Bithday&dates=20201231T193000Z/20201231T223000Z&details=With%20clowns%20and%20stuff&location=North%20Pole

EDIT based on comments:

If you have line breaks in your result set and want to remove them, make your query this way:

SELECT
    REPLACE(REPLACE(YourColumn1,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn2,CHAR(13),' '),CHAR(10),' ')
   ,REPLACE(REPLACE(YourColumn3,CHAR(13),' '),CHAR(10),' ')
   --^^^^^^^^^^^^^^^           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^
   --only add the above code to strings that are having line breaks, not to numbers or dates
   FROM YourTable...
   WHERE ...

This will replace all the line breaks with a space character.

Run this to "get" all characters permitted in a char() and varchar():

;WITH AllNumbers AS
(
    SELECT 1 AS Number
    UNION ALL
    SELECT Number+1
        FROM AllNumbers
        WHERE Number+1<256
)
SELECT Number AS ASCII_Value,CHAR(Number) AS ASCII_Char FROM AllNumbers
OPTION (MAXRECURSION 256)

OUTPUT:

ASCII_Value ASCII_Char

If you use default workspace in Jenkins, this might occur. Use custom workspace location without any spaces.

You can easily use Apache File Utils. Look at function writeStringToFile. We use this library in our projects.

In my case the above suggestions did not work for me. Mine was little different scenario.

When i tried installing bundler using gem install bundler .. But i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the /Library/Ruby/Gems/2.3.0 directory.

then i tried using sudo gem install bundler then i was getting

ERROR:  While executing gem ... (Gem::FilePermissionError)
  You don't have write permissions for the /usr/bin directory.

then i tried with sudo gem install bundler -n /usr/local/bin ( Just /usr/bin dint work in my case ).

And then successfully installed bundler

EDIT: I use MacOS, maybe /usr/bin din't work for me for that reason (https://stackoverflow.com/a/34989655/3786657 comment )

"commentLine" is the name of function you are looking for. This function coment and uncoment with the same keybinding

You can use this

SHA stands for Secure Hash Algorithm while AES stands for Advanced Encryption Standard. So SHA is a suite of hashing algorithms. AES on the other hand is a cipher which is used to encrypt. SHA algorithms (SHA-1, SHA-256 etc...) will take an input and produce a digest (hash), this is typically used in a digital signing process (produce a hash of some bytes and sign with a private key).

Array.from (ES6)

function doSomthing() {
    ...
}

Use it like so:

Array.from(Array(length).keys()).forEach(doSomthing);

Or

Array.from({ length }, (v, i) => i).forEach(doSomthing);

Or

// array start counting from 1
Array.from({ length }, (v, i) => ++i).forEach(doSomthing);

INSERT INTO TARGET_TABLE SELECT * FROM SOURCE_TABLE;

EDIT: or if the tables have different structures you can also:

INSERT INTO TARGET_TABLE (`col1`,`col2`) SELECT `col1`,`col2` FROM SOURCE_TABLE;

EDIT: to constrain this..

INSERT INTO TARGET_TABLE (`col1_`,`col2_`) SELECT `col1`,`col2` FROM SOURCE_TABLE WHERE `foo`=1

Another option you can try is QueryPath. It's inspired by jQuery, but on the server in PHP and used in Drupal.

The intended use of App_data is to store application data for the web process to acess. It should not be viewable by the web and is a place for the web app to store and read data from.

We have found that adding the Apptentive cocoa pod to an existing Xcode project may potentially not include some of our required frameworks.

Check your linker flags:

Target > Build Settings > Other Linker Flags 

You should see -lApptentiveConnect listed as a linker flag:

... -ObjC -lApptentiveConnect ... 

You should also see our required Frameworks listed:

• Accelerate
• CoreData
• CoreText
• CoreGraphics
• CoreTelephony
• Foundation
• QuartzCore
• StoreKit
• SystemConfiguration

• UIKit

  -ObjC -lApptentiveConnect -framework Accelerate -framework CoreData -framework CoreGraphics -framework CoreText -framework Foundation -framework QuartzCore -framework SystemConfiguration -framework UIKit -framework CoreTelephony -framework StoreKit

When you say it's "a valid resource bundle" - is it a property resource bundle? If so, the simplest way of loading it probably:

try (FileInputStream fis = new FileInputStream("c:/temp/mybundle.txt")) {
  return new PropertyResourceBundle(fis);
}

A little extension to the above answers. The trailing > directs the input into the file, overwriting existing content. However, one particularly convenient use is the double arrow >> that appends, adding your new content to the end of the file, as in:

cat <<EOF >> /etc/fstab
data_server:/var/sharedServer/authority/cert /var/sharedFolder/sometin/authority/cert nfs
data_server:/var/sharedServer/cert   /var/sharedFolder/sometin/vsdc/cert nfs
EOF

This extends your fstab without you having to worry about accidentally modifying any of its contents.

Simple variant:

Regex.Replace(input, @"\r\n|\r|\n", "\r\n")

For better performance:

static Regex newline_pattern = new Regex(@"\r\n|\r|\n", RegexOptions.Compiled);
[...]
    newline_pattern.Replace(input, "\r\n");

Can you do this on the server, using Apache's mod_rewrite for example? If not, you can use the window.location.replace method to erase the current URL from the back/forward history (to not break the back button) and go to the root of the web site:

window.location.replace('/');

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative
 #   expr       min         lq       mean     median         uq      max   neval

For ncol = 10, the results are slighjtly different:

Edit: Passing the operator as a reference doesnt work. For simplicity, understand it as a function pointer. You just send the pointer, not a reference. I think you are trying to write something like this.

struct Square
{
    double operator()(double number) { return number * number; }
};

template <class Function>
double integrate(Function f, double a, double b, unsigned int intervals)
{
    double delta = (b - a) / intervals, sum = 0.0;

    while(a < b)
    {
        sum += f(a) * delta;
        a += delta;
    }

    return sum;
}

. .

std::cout << "interval : " << i << tab << tab << "intgeration = "
 << integrate(Square(), 0.0, 1.0, 10) << std::endl;

Whenever you want to get the changes from master into your work branch, do a git rebase <remote>/master. If there are any conflicts. resolve them.

When your work branch is ready, rebase again and then do git push <remote> HEAD:master. This will update the master branch on remote (central repo).

To create an array of unlimited items of any sort of type:

typedef struct STRUCT_SS_VECTOR {
    size_t size;
    void** items;
} ss_vector;


ss_vector* ss_init_vector(size_t item_size) {
    ss_vector* vector;
    vector = malloc(sizeof(ss_vector));
    vector->size = 0;
    vector->items = calloc(0, item_size);

    return vector;
}

void ss_vector_append(ss_vector* vec, void* item) {
    vec->size++;
    vec->items = realloc(vec->items, vec->size * sizeof(item));
    vec->items[vec->size - 1] = item;
};

void ss_vector_free(ss_vector* vec) {
    for (int i = 0; i < vec->size; i++)
        free(vec->items[i]);

    free(vec->items);
    free(vec);
}

and how to use it:

// defining some sort of struct, can be anything really
typedef struct APPLE_STRUCT {
    int id;
} apple;

apple* init_apple(int id) {
    apple* a;
    a = malloc(sizeof(apple));
    a-> id = id;
    return a;
};


int main(int argc, char* argv[]) {
    ss_vector* vector = ss_init_vector(sizeof(apple));

    // inserting some items
    for (int i = 0; i < 10; i++)
        ss_vector_append(vector, init_apple(i));


    // dont forget to free it
    ss_vector_free(vector);

    return 0;
}

This vector/array can hold any type of item and it is completely dynamic in size.

You can't. Bear in mind that foo is a variable of type string.

You could create your own type, say BoundedString, and have:

BoundedString foo = new BoundedString(5);
foo.Text = "hello"; // Fine
foo.Text = "naughty"; // Throw an exception or perhaps truncate the string

... but you can't stop a string variable from being set to any string reference (or null).

Of course, if you've got a string property, you could do that:

private string foo;
public string Foo
{
    get { return foo; }
    set
    {
        if (value.Length > 5)
        {
            throw new ArgumentException("value");
        }
        foo = value;
    }
}

Does that help you in whatever your bigger context is?

I solved this issue in Windows using this format for the full path:

sdk.dir=C:/Users/xxxx/AppData/Local/Android/Sdk

As theon noted, REST is not a standard. However, if you are looking to implement a standards based URI convention, you might consider the oData URI convention. Ver 4 has been approved as an OASIS standard and libraries exists for oData for various languages including Java via Apache Olingo. Don't let the fact that it's a spawn from Microsoft put you off since it's gained support from other industry player's as well, which include Red Hat, Citrix, IBM, Blackberry, Drupal, Netflix Facebook and SAP

Ok, per pix0r's, Sparks' and Dave's answers it looks like there are three ways to do this:

Virtual Hosts

1. Open C:\xampp\apache\conf\extra\httpd-vhosts.conf.
2. Un-comment ~line 19 (NameVirtualHost *:80).

3. Add your virtual host (~line 36):

   <VirtualHost *:80>
       DocumentRoot C:\Projects\transitCalculator\trunk
       ServerName transitcalculator.localhost
       <Directory C:\Projects\transitCalculator\trunk>
           Order allow,deny
           Allow from all
       </Directory>
   </VirtualHost>
   

4. Open your hosts file (C:\Windows\System32\drivers\etc\hosts).

5. Add

   127.0.0.1 transitcalculator.localhost #transitCalculator
   

   to the end of the file (before the Spybot - Search & Destroy stuff if you have that installed).

6. Save (You might have to save it to the desktop, change the permissions on the old hosts file (right click > properties), and copy the new one into the directory over the old one (or rename the old one) if you are using Vista and have trouble).
7. Restart Apache.

Now you can access that directory by browsing to http://transitcalculator.localhost/.

Make an Alias

1. Starting ~line 200 of your http.conf file, copy everything between <Directory "C:/xampp/htdocs"> and </Directory> (~line 232) and paste it immediately below with C:/xampp/htdocs replaced with your desired directory (in this case C:/Projects) to give your server the correct permissions for the new directory.

2. Find the <IfModule alias_module></IfModule> section (~line 300) and add

   Alias /transitCalculator "C:/Projects/transitCalculator/trunk"
   

   (or whatever is relevant to your desires) below the Alias comment block, inside the module tags.

Change your document root

1. Edit ~line 176 in C:\xampp\apache\conf\httpd.conf; change DocumentRoot "C:/xampp/htdocs" to #DocumentRoot "C:/Projects" (or whatever you want).

2. Edit ~line 203 to match your new location (in this case C:/Projects).

Notes:

• You have to use forward slashes "/" instead of back slashes "\".
• Don't include the trailing "/" at the end.
• restart your server.

You can use zip:

>>> a = [1, 2, 3]
>>> b = ['a', 'b', 'c']
>>> for x, y in zip(a, b):
...   print x, y
... 
1 a
2 b
3 c

In C, a string is actually stored as an array of characters, so the 'string pointer' is pointing to the first character. For instance,

char myString[] = "This is some text";

You can access any character as a simple char by using myString as an array, thus:

char myChar = myString[6];
printf("%c\n", myChar); // Prints s

Hope this helps! David

The real problem is that you are using dynamic return type in the FacebookClient Get method. And although you use a method for serializing, the JSON converter cannot deserialize this Object after that.

Use insted of:

dynamic result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}); 
string jsonstring = JsonConvert.SerializeObject(result);

something like that:

string result = client.Get("fql", new { q = "select target_id,target_type from connection where source_id = me()"}).ToString();

Then you can use DeserializeObject method:

var datalist = JsonConvert.DeserializeObject<List<RootObject>>(result);

Hope this helps.

Import timedelta and date first.

from datetime import timedelta, date

And date.today() will return today's datetime, may be you want

EndDate = date.today() + timedelta(days=10)

You've got "Bad Status" its because the target file cannot find or not present, like for example you call README file which is not in the current directory.

I hope you won't mind a slight tangent, but thought you may be interested to know that besides F (for float), D (for double), and L (for long), a proposal has been made to add suffixes for byte and short—Y and S respectively. This would eliminate to the need to cast to bytes when using literal syntax for byte (or short) arrays. Quoting the example from the proposal:

MAJOR BENEFIT: Why is the platform better if the proposal is adopted?

cruddy code like

 byte[] stuff = { 0x00, 0x7F, (byte)0x80,  (byte)0xFF};

can be recoded as

 byte[] ufum7 = { 0x00y, 0x7Fy, 0x80y, 0xFFy };

Joe Darcy is overseeing Project Coin for Java 7, and his blog has been an easy way to track these proposals.

You can create lists and convert them into arrays or you can create array using numpy module. Below are few examples to illustrate the same. Numpy also makes it easier to work with multi-dimensional arrays.

import numpy as np
a = np.array([1, 2, 3, 4])

#For custom inputs
a = np.array([int(x) for x in input().split()])

You can also reshape this array into a 2X2 matrix using reshape function which takes in input as the dimensions of the matrix.

mat = a.reshape(2, 2)

The SSL errors are often thrown by network management software such as Cyberroam.

To answer your question,

you will have to enter badidea into Chrome every time you visit a website.

You might at times have to enter it more than once, as the site may try to pull in various resources before load, hence causing multiple SSL errors

Are you sure your web service is deployed correctly to the enviornment that is NOT working. Looks like the type is out of date.

Anurags answer is basically correct. But to support Object.keys(obj) in older browsers as well you can use the code below that is copied from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/keys . It adds the Object.keys(obj) method if it's not available from the browser.

if (!Object.keys) {
 Object.keys = (function() {
 'use strict';
 var hasOwnProperty = Object.prototype.hasOwnProperty,
    hasDontEnumBug = !({ toString: null }).propertyIsEnumerable('toString'),
    dontEnums = [
      'toString',
      'toLocaleString',
      'valueOf',
      'hasOwnProperty',
      'isPrototypeOf',
      'propertyIsEnumerable',
      'constructor'
    ],
    dontEnumsLength = dontEnums.length;

return function(obj) {
  if (typeof obj !== 'object' && (typeof obj !== 'function' || obj === null)) {
    throw new TypeError('Object.keys called on non-object');
  }

  var result = [], prop, i;

  for (prop in obj) {
    if (hasOwnProperty.call(obj, prop)) {
      result.push(prop);
    }
  }

  if (hasDontEnumBug) {
    for (i = 0; i < dontEnumsLength; i++) {
      if (hasOwnProperty.call(obj, dontEnums[i])) {
        result.push(dontEnums[i]);
      }
    }
  }
  return result;
};
}());
}

The query below will give you a list of all users and their permissions on the table in a schema.

select a.schemaname, a.tablename, b.usename,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'select') as has_select,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'insert') as has_insert,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'update') as has_update,
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'delete') as has_delete, 
  HAS_TABLE_PRIVILEGE(usename, quote_ident(schemaname) || '.' || quote_ident(tablename), 'references') as has_references 
from pg_tables a, pg_user b 
where a.schemaname = 'your_schema_name' and a.tablename='your_table_name';

More details on has_table_privilages can be found here.

I solved my problem using entire address where my code is: Before:

if(!exists("foo", mode="function")) source("utils.r")

After:

if(!exists("foo", mode="function")) source("C:/tests/utils.r")

That's how I've added mine in profiles json table,

{
    "guid": "{00000000-0000-0000-ba54-000000000002}",
    "name": "Git",
    "commandline": "C:/Program Files/Git/bin/bash.exe --login",
    "icon": "%PROGRAMFILES%/Git/mingw64/share/git/git-for-windows.ico",
    "startingDirectory": "%USERPROFILE%",
    "hidden": false
}

First, There is no such css-changes event out of the box, but you can create one by your own, as onchange is for :input elements only. not for css changes.

There are two ways to track css changes.

1. Examine the DOM element for css changes every x time(500 milliseconds in the example).
2. Trigger an event when you change the element css.
3. Use the DOMAttrModified mutation event. But it's deprecated, so I'll skip on it.

First way:

var $element = $("#elementId");
var lastHeight = $("#elementId").css('height');
function checkForChanges()
{
    if ($element.css('height') != lastHeight)
    {
        alert('xxx');
        lastHeight = $element.css('height'); 
    }

    setTimeout(checkForChanges, 500);
}

Second way:

$('#mainContent').bind('heightChange', function(){
        alert('xxx');
    });


$("#btnSample1").click(function() {
    $("#mainContent").css('height', '400px');
    $("#mainContent").trigger('heightChange'); //<====
    ...
});    

If you control the css changes, the second option is a lot more elegant and efficient way of doing it.

Documentations:

• bind: Description: Attach a handler to an event for the elements.
• trigger: Description: Execute all handlers and behaviors attached to the matched elements for the given event type.

var filtered = projects;
foreach (var tag in filteredTags) {
  filtered = filtered.Where(p => p.Tags.Contains(tag))
}

The nice thing with this approach is that you can refine search results incrementally.

In order to give a value in the table, we need to give a command:

php artisan make:migration create_users_table

and after then this command line

php artisan migrate

......

Olmo's suggestion is very good, but I'd add this: If you're not sure about the size, it's better to make it a little bigger than a little smaller. When a list is full, keep in mind it will double its size to add more elements.

For example: suppose you will need about 50 elements. If you use a 50 elements size and the final number of elements is 51, you'll end with a 100 sized list with 49 wasted positions.

Create a page which contains two links- one at the top and one at the bottom. On clicking the top link, the page has to scroll down to the bottom of the page where bottom link is present. On clicking the bottom link, the page has to scroll up to the top of the page.

public static List<HtmlNode> GetTagsWithClass(string html,List<string> @class)
    {
        // LoadHtml(html);           
        var result = htmlDocument.DocumentNode.Descendants()
            .Where(x =>x.Attributes.Contains("class") && @class.Contains(x.Attributes["class"].Value)).ToList();          
        return result;
    }      

(Feature Panel).setOpaque(false);

Hope this helps.

This seems to work:

def sanitize_utf8(string)
  return nil if string.nil?
  return string if string.valid_encoding?
  string.chars.select { |c| c.valid_encoding? }.join
end

Some transportation protocols only allow alphanumerical characters to be transmitted. Just imagine a situation where control characters are used to trigger special actions and/or that only supports a limited bit width per character. Base64 transforms any input into an encoding that only uses alphanumeric characters, +, / and the = as a padding character.

I would guess that the location of the compiler is defined in a POM for the compiler plugin to be in the JRE location displayed, instead of the JDK location you have JAVA_HOME pointing to.

You can get this error if you have variable str and trying to call str() function.

<?php 
     echo '<p>Hello World</p>' 
?>

As simple as placing something along those lines within your HTML assuming your server is set-up to execute PHP in files with the HTML extension.

That's because that's an SQL function, not PHP. You can use PDO::lastInsertId().

Like:

$stmt = $db->prepare("...");
$stmt->execute();
$id = $db->lastInsertId();

If you want to do it with SQL instead of the PDO API, you would do it like a normal select query:

$stmt = $db->query("SELECT LAST_INSERT_ID()");
$lastId = $stmt->fetchColumn();

I know this is old but I think this will help anyone else who comes looking...

SELECT CAST(COUNT(ProductID) AS bit) AS [EXISTS] FROM Products WHERE(ProductID = @ProductID)

This will ALWAYS return TRUE if exists and FALSE if it doesn't (as opposed to no row).

If you want to copy file not using absolute path, relative path in other words:

Don't forget to write backslash in the path AND NOT slash

Example:

copy children-folder\file.something .\other-children-folder

PS: absolute path can be retrieved using these wildcards called "batch parameters"

@echo off
echo %%~dp0 is "%~dp0"
echo %%0 is "%0"
echo %%~dpnx0 is "%~dpnx0"
echo %%~f1 is "%~f1"
echo %%~dp0%%~1 is "%~dp0%~1"

Check documentation here about copy: https://technet.microsoft.com/en-us/library/bb490886.aspx

And also here for batch parameters documentation: https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/percent.mspx?mfr=true

First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects.

After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example:

Dim xlApp as Excel.Application

Let's say you added an Excel Workbook Object in your Form and named it xLObject.

Here is how you Access a Sheet of this Object and change a Range

Dim sheet As Excel.Worksheet
Set sheet = xlObject.Object.Sheets(1)
sheet.Range("A1") = "Hello World"

(I copied the above from my answer to this question)

Another way to use Excel in Access is to start Excel through a Access Module (the way shahkalpesh described it in his answer)

You can see Main Answer for complete information about data binding errors and solutions. I will try to tell some important points below.

5 Tips that I use to solve binding issues.

Assuming that you have enabled data binding in build.gradle and you have converted your layout to binding layout.

First of all binding class auto generate when you convert layout to binding layout. Still sometimes it is not generated when background threads are not working. Here are some tips for you to resolve this.

(1) Name of generated class

Layout name is in snake_case activity_main.xml

Data binding class will be in PascalCase like ActivityMainBinding.

(2). Type full name of Binding class

I felt sometimes when you type ActivityMai..., then it does not show suggestion, but that does not mean class is not generated. In that case you should type full name of expected generated class. Like type ActivityMainBinding and it will show import popup. (That's what i faced many times.)

Still not getting import suggestion. Try manual import.

import <yourpackage>databinding.ActivityMainBinding;

(3). Rebuild Project

If still your class is not generated. (Some time when we paste layout file, then it happens). Then Rebuild Project from Build> Rebuild (Not Build or Make project). It will generate your data binding class. (Rebuild does Magic for me all times.)

(4) If you have created an <variable in your layout and it does not show up its setter and getter in data binding class, then follow 4th point.

(5) Still if your class is not generating then you should check if build is not failing due to an error in your layout file. Data binding class will generate with a successful build.

This is all what i do to solve my data binding errors. If you get any further issue, you can comment here.

Source answer

To put it nice and simply, get(int index) returns the element at the specified index.

So say we had an ArrayList of Strings:

List<String> names = new ArrayList<String>();
names.add("Arthur Dent");
names.add("Marvin");
names.add("Trillian");
names.add("Ford Prefect");

Which can be visualised as: Where 0, 1, 2, and 3 denote the indexes of the ArrayList.

Say we wanted to retrieve one of the names we would do the following: String name = names.get(1); Which returns the name at the index of 1.

So if we were to print out the name System.out.println(name); the output would be Marvin - Although he might not be too happy with us disturbing him.

I'd like to point out that if you want to play with threads in C++, if you use cout you can get some interesting results.

Consider this code:

#include <string>
#include <iostream>
#include <thread>

using namespace std;

void task(int taskNum, string msg) {
    for (int i = 0; i < 5; ++i) {
        cout << "#" << taskNum << ": " << msg << endl;
    }
}

int main() {
    thread t1(task, 1, "AAA");
    thread t2(task, 2, "BBB");
    t1.join();
    t2.join();
    return 0;
}

// g++ ./thread.cpp -o thread.out -ansi -pedantic -pthread -std=c++0x

Now, the output comes all shuffled. It can yield different results too, try executing several times:

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

##12::  ABABAB

You can use printf to get it right, or you can use mutex.

#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB
#1: AAA
#2: BBB

Have fun!

You can also specify context location relatively to current classpath, which may be preferable

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

No you can't since IEnumerable is an interface.

You should be able to create an empty instance of most non-interface types which implement IEnumerable, e.g.:-

IEnumerable<object> a = new object[] { };

or

IEnumerable<object> a = new List<object>();

You need to use the change directory command 'cd' to change directory

cd C:\Users\MyName\Desktop

you can use cd \d to change the drive as well.

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

Select *  from  emp where joindate between date1 and date2;

But this query not show proper data.

Eg

1-jan-2013 to 12-jan-2013.

But it's show data

1-jan-2013 to 11-jan-2013.

Synchronized on the method declaration is syntactical sugar for this:

 public void addA() {
     synchronized (this) {
          a++;
     }
  }

On a static method it is syntactical sugar for this:

 ClassA {
     public static void addA() {
          synchronized(ClassA.class) {
              a++;
          }
 }

I think if the Java designers knew then what is understood now about synchronization, they would not have added the syntactical sugar, as it more often than not leads to bad implementations of concurrency.

Activity::hasWindowFocus() returns you the boolean you need.

public class ActivityForegroundChecker extends TimerTask
{
    private static final long FOREGROUND_CHECK_PERIOD = 5000;
    private static final long FIRST_DELAY             = 3000;

    private Activity m_activity;
    private Timer    m_timer;

    public ActivityForegroundChecker (Activity p_activity)
    {
        m_activity = p_activity;
    }

    @Override
    public void run()
    {
        if (m_activity.hasWindowFocus() == true) {
            // Activity is on foreground
            return;
        }
        // Activity is on background.
    }

    public void start ()
    {
        if (m_timer != null) {
            return;
        }
        m_timer = new Timer();
        m_timer.schedule(this, FIRST_DELAY, FOREGROUND_CHECK_PERIOD);
    }

    public void stop ()
    {
        if (m_timer == null) {
            return;
        }
        m_timer.cancel();
        m_timer.purge();
        m_timer = null;
    }
}

Here is an example class to check your activites' visibility from wherever you are.

Remember that if you show a dialog, the result will be false since the dialog will have the main focus. Other than that it's really handy and more reliable than suggested solutions.

No, "message" is not forbidden. It's just deprecated. You application will work fine with using message. But you may want to get rid of the deprecation error, of course.

When you create custom Exception classes for your application, many of them do not subclass just from Exception, but from others, like ValueError or similar. Then you have to adapt to their usage of variables.

And if you have many exceptions in your application it's usually a good idea to have a common custom base class for all of them, so that users of your modules can do

try:
    ...
except NelsonsExceptions:
    ...

And in that case you can do the __init__ and __str__ needed there, so you don't have to repeat it for every exception. But simply calling the message variable something else than message does the trick.

In any case, you only need the __init__ or __str__ if you do something different from what Exception itself does. And because if the deprecation, you then need both, or you get an error. That's not a whole lot of extra code you need per class. ;)

Starting with your data frame DF, you could use the data.table package:

library(data.table)

## EDIT: As suggested by @MichaelChirico, setDT converts a
## data.frame to a data.table by reference and is preferred
## if you don't mind losing the data.frame
setDT(DF)

# EDIT: To get the column name 'Mean':

DF[, .(Mean = rowMeans(.SD)), by = ID]

#      ID     Mean
# [1,]  A 3.666667
# [2,]  B 4.333333
# [3,]  C 3.333333
# [4,]  D 4.666667
# [5,]  E 4.333333

iterate through the array and check its name value.

Integer division $x divided by $y ...

$z = -1 & $x / $y

How does it work?

$x / $y

return the floating point division

&

perform a bit-wise AND

-1

stands for

&HFFFFFFFF

for the largest integer ... whence

$z = -1 & $x / $y

gives the integer division ...

$argv[0]; // the script name
$argv[1]; // the first parameter
$argv[2]; // the second parameter

If you want to all the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

<?php
if ($_GET) {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
} else {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
?>

To call from command line chmod 755 /var/www/webroot/index.php and use

/usr/bin/php /var/www/webroot/index.php arg1 arg2

To call from the browser, use

http://www.mydomain.com/index.php?argument1=arg1&argument2=arg2

Note too that Hyperlink does not have to be used for navigation. You can connect it to a command.

For example:

<TextBlock>
  <Hyperlink Command="{Binding ClearCommand}">Clear</Hyperlink>
</TextBlock>

Add a unique class to the links and a javascript that prevents default on links with this class:

<a href="#" class="prevent-default" 
   onclick="$('.comment .hidden').toggle();">Show comments</a>

<script>
  $(document).ready(function(){

    $("a.prevent-default").click(function(event) {
         event.preventDefault(); 
          });
  });
</script>

Both kinds of enclosed characters are strings. One type of quote is conveniently used to enclose the other type of quote. "'" and '"'. The biggest difference between the types of quotes is that enclosed identifier references are substituted for inside double quotes, but not inside single quotes.

This is a very common question seen on Stackoverflow.

The important part here is not the command displayed in the error, but what the actual error tells you instead.

a Quick breakdown on why this error is received.

cmd.exe Being a terminal window relies on input and system Environment variables, in order to perform what you request it to do. it does NOT know the location of everything and it also does not know when to distinguish between commands or executable names which are separated by whitespace like space and tab or commands with whitespace as switch variables.

How do I fix this:

When Actual Command/executable fails

First we make sure, is the executable actually installed? If yes, continue with the rest, if not, install it first.

If you have any executable which you are attempting to run from cmd.exe then you need to tell cmd.exe where this file is located. There are 2 ways of doing this.

1. specify the full path to the file.

   "C:\My_Files\mycommand.exe"

2. Add the location of the file to your environment Variables.

Goto:
------> Control Panel-> System-> Advanced System Settings->Environment Variables

In the System Variables Window, locate path and select edit

Now simply add your path to the end of the string, seperated by a semicolon ; as:

;C:\My_Files\

Save the changes and exit. You need to make sure that ANY cmd.exe windows you had open are then closed and re-opened to allow it to re-import the environment variables. Now you should be able to run mycommand.exe from any path, within cmd.exe as the environment is aware of the path to it.

When C:\Program or Similar fails

This is a very simple error. Each string after a white space is seen as a different command in cmd.exe terminal, you simply have to enclose the entire path in double quotes in order for cmd.exe to see it as a single string, and not separate commands.

So to execute C:\Program Files\My-App\Mobile.exe simply run as:

"C:\Program Files\My-App\Mobile.exe"

Matt Zeunert's version with use arraw function (ES6)

const nums = a.split(',').map(x => parseInt(x, 10));

Computer Management->Shared Folders->Open Files

There's one thing to keep in mind.

Mysqli does not support fetch_assoc() function which would return the columns with keys representing column names. Of course it's possible to write your own function to do that, it's not even very long, but I had really hard time writing it (for non-believers: if it seems easy to you, try it on your own some time and don't cheat :) )

Python 2

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u prefix on strings, i.e. u'€' or by decoding a string with mystr.decode('utf-8') using the appropriate encoding.

The best practice is to decode all text data as it's read, rather than decoding mid-program. The io module provides an open() method which decodes text data to Unicode strings as it's read.

ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write() method.

Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write() and adds the relevant header.

Presuming your input file is UTF-8 encoded (0xC2 is common UTF-8 lead byte), putting everything together, and using the with statement, your code should look like:

with io.open('myText.txt', "r", encoding='utf-8') as f:
    data = f.read()

root = ET.Element("add")
doc = ET.SubElement(root, "doc")

field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data

tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)

Output:

<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>

While the example works, its not the correct way to handle the streams...

You need to ensure the closing of the files/streams with the using clause.. Also, add try/catch to handle IO errors...

       public void DownloadAll()
    {
        string host = @"sftp.domain.com";
        string username = "myusername";
        string password = "mypassword";

        string remoteDirectory = "/RemotePath/";
        string localDirectory = @"C:\LocalDriveFolder\Downloaded\";

        using (var sftp = new SftpClient(host, username, password))
        {
            sftp.Connect();
            var files = sftp.ListDirectory(remoteDirectory);

            foreach (var file in files)
            {
                string remoteFileName = file.Name;
                if ((!file.Name.StartsWith(".")) && ((file.LastWriteTime.Date == DateTime.Today))

                    using (Stream file1 = File.OpenWrite(localDirectory + remoteFileName))
                    { 
                        sftp.DownloadFile(remoteDirectory + remoteFileName, file1);
                    }
            }

        }
    }

I think for REST, you just have to make a decision on the behavior for that particular system in which case, I think the "right" answer would be one of a couple answers given here. If you want the request to stop and behave as if the client made a mistake that it needs to fix before continuing, then use 409. If the conflict really isn't that important and want to keep the request going, then respond by redirecting the client to the entity that was found. I think proper REST APIs should be redirecting (or at least providing the location header) to the GET endpoint for that resource following a POST anyway, so this behavior would give a consistent experience.

EDIT: It's also worth noting that you should consider a PUT since you're providing the ID. Then the behavior is simple: "I don't care what's there right now, put this thing there." Meaning, if nothing is there, it'll be created; if something is there it'll be replaced. I think a POST is more appropriate when the server manages that ID. Separating the two concepts basically tells you how to deal with it (i.e. PUT is idempotent so it should always work so long as the payload validates, POST always creates, so if there is a collision of IDs, then a 409 would describe that conflict).

Wouldn't this "d+|D+" do the job instead of the cumbersome: "(?<=\\D)(?=\\d)|(?<=\\d)(?=\\D)" ?

Full example:

CREATE TRIGGER [dbo].[trig_020_Original_010_010_Gamechanger]
   ON  [dbo].[T_Original]
   AFTER UPDATE
AS 
BEGIN
    -- SET NOCOUNT ON added to prevent extra result sets from
    -- interfering with SELECT statements.
    SET NOCOUNT ON;
    DECLARE @Old_Gamechanger int;
    DECLARE @New_Gamechanger int;

    -- Insert statements for trigger here
    SELECT @Old_Gamechanger = Gamechanger from DELETED;
    SELECT @New_Gamechanger = Gamechanger from INSERTED;

    IF @Old_Gamechanger != @New_Gamechanger

        BEGIN

            INSERT INTO [dbo].T_History(ChangeDate, Reason, Callcenter_ID, Old_Gamechanger, New_Gamechanger)
            SELECT GETDATE(), 'Time for a change', Callcenter_ID, @Old_Gamechanger, @New_Gamechanger
                FROM deleted
            ;

        END

END

The documentation of the file module says

If state=file, the file will NOT be created if it does not exist, see the copy or template module if you want that behavior.

So we use the copy module, using force=no to create a new empty file only when the file does not yet exist (if the file exists, its content is preserved).

- name: ensure file exists
  copy:
    content: ""
    dest: /etc/nologin
    force: no
    group: sys
    owner: root
    mode: 0555

This is a declarative and elegant solution.

Make sure that you really use the bootstrap jquery modal and not another jquery modal.

Wasted way too much time on this...

DOMDocument::loadHTML will treat your string as being in ISO-8859-1 unless you tell it otherwise. This results in UTF-8 strings being interpreted incorrectly.

If your string doesn't contain an XML encoding declaration, you can prepend one to cause the string to be treated as UTF-8:

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML('<?xml encoding="utf-8" ?>' . $profile);
echo $dom->saveHTML();

If you cannot know if the string will contain such a declaration already, there's a workaround in SmartDOMDocument which should help you:

$profile = '<p>???????????????????????9</p>';
$dom = new DOMDocument();
$dom->loadHTML(mb_convert_encoding($profile, 'HTML-ENTITIES', 'UTF-8'));
echo $dom->saveHTML();

This is not a great workaround, but since not all characters can be represented in ISO-8859-1 (like these katana), it's the safest alternative.

While using innerHTML.replace will work and is pretty fast, this will break the DOM state. You can replicate this by setting "autofocus" on an input field and then changing innerHTML on body, it will loose focus.

A less destructive approach is:

// retrives all childNodes of body
var childNodes = document.body.childNodes;

// start replacing
replaceInNodes(childNodes,"search","replace");

function replaceInNodes(nodes,search,replace){
    // iterate through all nodes
    for (var i = 0; i < nodes.length; i++) { 
            var curNode = nodes[i];
            // if the node has attributes, let us look at those
            // i.E. we want to change "John" in the input placeholder to "Peter" - <input type="text" value="John">
            if(curNode.attributes !== undefined){
                var curNodeAttributes = curNode.attributes;
                for (var ii = 0; ii < curNodeAttributes.length; ii++) {
                    // replace attribute values
                    curNodeAttributes[ii].nodeValue = curNodeAttributes[ii].nodeValue.replace(search, replace);
                }   
            }
            // It is a "TEXT_NODE"
            // i.E. <span>John</span>
            if(curNode.nodeType == 3){
                curNode.data = this.injectIntoString(curNode.data);
            }
            // It is a "ELEMENT_NODE", meaning we need to go deeper
            if(curNode.nodeType == 1){
                this.replaceInNodes(curNode.childNodes);
            }
        }
}

Use #include <windows.h> instead of #include <windef.h>.

From the windows.h wikipedia page:

There are a number of child header files that are automatically included with windows.h. Many of these files cannot simply be included by themselves (they are not self-contained), because of dependencies.

windef.h is one of the files automatically included with windows.h.

AWT is a Java interface to native system GUI code present in your OS. It will not work the same on every system, although it tries.

Swing is a more-or-less pure-Java GUI. It uses AWT to create an operating system window and then paints pictures of buttons, labels, text, checkboxes, etc., into that window and responds to all of your mouse-clicks, key entries, etc., deciding for itself what to do instead of letting the operating system handle it. Thus Swing is 100% portable and is the same across platforms (although it is skinnable and has a "pluggable look and feel" that can make it look more or less like how the native windows and widgets would look).

These are vastly different approaches to GUI toolkits and have a lot of consequences. A full answer to your question would try to explore all of those. :) Here are a couple:

AWT is a cross-platform interface, so even though it uses the underlying OS or native GUI toolkit for its functionality, it doesn't provide access to everything that those toolkits can do. Advanced or newer AWT widgets that might exist on one platform might not be supported on another. Features of widgets that aren't the same on every platform might not be supported, or worse, they might work differently on each platform. People used to invest lots of effort to get their AWT applications to work consistently across platforms - for instance, they may try to make calls into native code from Java.

Because AWT uses native GUI widgets, your OS knows about them and handles putting them in front of each other, etc., whereas Swing widgets are meaningless pixels within a window from your OS's point of view. Swing itself handles your widgets' layout and stacking. Mixing AWT and Swing is highly unsupported and can lead to ridiculous results, such as native buttons that obscure everything else in the dialog box in which they reside because everything else was created with Swing.

Because Swing tries to do everything possible in Java other than the very raw graphics routines provided by a native GUI window, it used to incur quite a performance penalty compared to AWT. This made Swing unfortunately slow to catch on. However, this has shrunk dramatically over the last several years due to more optimized JVMs, faster machines, and (I presume) optimization of the Swing internals. Today a Swing application can run fast enough to be serviceable or even zippy, and almost indistinguishable from an application using native widgets. Some will say it took far too long to get to this point, but most will say that it is well worth it.

Finally, you might also want to check out SWT (the GUI toolkit used for Eclipse, and an alternative to both AWT and Swing), which is somewhat of a return to the AWT idea of accessing native Widgets through Java.

for i in *.xls ; do 
  [[ -f "$i" ]] || continue
  xls2csv "$i" "${i%.xls}.csv"
done

The first line in the do checks if the "matching" file really exists, because in case nothing matches in your for, the do will be executed with "*.xls" as $i. This could be horrible for your xls2csv.

why not just declare that function inside the cshtml file?

@functions{
    public string GetSomeString(){
        return string.Empty;
    }
}

<h2>index</h2>
@GetSomeString()

Since there are no events available to signal when the socket is disconnected, you will have to poll it at a frequency that is acceptable to you.

Using this extension method, you can have a reliable method to detect if a socket is disconnected.

static class SocketExtensions
{
  public static bool IsConnected(this Socket socket)
  {
    try
    {
      return !(socket.Poll(1, SelectMode.SelectRead) && socket.Available == 0);
    }
    catch (SocketException) { return false; }
  }
}
