The most important difference to be aware of is that with a stream opened in text mode you get newline translation on non-*nix systems (it's also used for network communications, but this isn't supported by the standard library). In *nix newline is just ASCII linefeed, \n, both for internal and external representation of text. In Windows the external representation often uses a carriage return + linefeed pair, "CRLF" (ASCII codes 13 and 10), which is converted to a single \n on input, and conversely on output.

From the C99 standard (the N869 draft document), §7.19.2/2,

A text stream is an ordered sequence of characters composed into lines, each line consisting of zero or more characters plus a terminating new-line character. Whether the last line requires a terminating new-line character is implementation-defined. Characters may have to be added, altered, or deleted on input and output to conform to differing conventions for representing text in the host environment. Thus, there need not be a one- to-one correspondence between the characters in a stream and those in the external representation. Data read in from a text stream will necessarily compare equal to the data that were earlier written out to that stream only if: the data consist only of printing characters and the control characters horizontal tab and new-line; no new-line character is immediately preceded by space characters; and the last character is a new-line character. Whether space characters that are written out immediately before a new-line character appear when read in is implementation-defined.

And in §7.19.3/2

Binary files are not truncated, except as defined in 7.19.5.3. Whether a write on a text stream causes the associated file to be truncated beyond that point is implementation- defined.

About use of fseek, in §7.19.9.2/4:

For a text stream, either offset shall be zero, or offset shall be a value returned by an earlier successful call to the ftell function on a stream associated with the same file and whence shall be SEEK_SET.

About use of ftell, in §17.19.9.4:

The ftell function obtains the current value of the file position indicator for the stream pointed to by stream. For a binary stream, the value is the number of characters from the beginning of the file. For a text stream, its file position indicator contains unspecified information, usable by the fseek function for returning the file position indicator for the stream to its position at the time of the ftell call; the difference between two such return values is not necessarily a meaningful measure of the number of characters written or read.

I think that’s the most important, but there are some more details.

This message digital envelope routines: EVP_DecryptFInal_ex: bad decrypt can also occur when you encrypt and decrypt with an incompatible versions of openssl.

The issue I was having was that I was encrypting on Windows which had version 1.1.0 and then decrypting on a generic Linux system which had 1.0.2g.

It is not a very helpful error message!

Working solution:

A possible solution from @AndrewSavinykh that worked for many (see the comments):

Default digest has changed between those versions from md5 to sha256. One can specify the default digest on the command line as -md sha256 or -md md5 respectively

If you are using macOS sierra there is a update in PHP version. you need to have Entrust.net Certificate Authority (2048) file added to the PHP code. more info check accepted answer here Push Notification in PHP using PEM file

Use the a mode. It stands for append.

$myfile = fopen("logs.txt", "a") or die("Unable to open file!");
$txt = "user id date";
fwrite($myfile, "\n". $txt);
fclose($myfile);

Another approach using the new Swift 2 syntax is to use guard and nest it all in one conditional.

guard let touch = object.AnyObject() as? UITouch, let picker = touch.view as? UIPickerView else {
    return //Do Nothing
}
//Do something with picker

This is what I did.
First, just override the jumbotron class, and do the following:

.jumbotron{
    background: url("bg.jpg") no-repeat center center; 
    -webkit-background-size: 100% 100%;
    -moz-background-size: 100% 100%;
    -o-background-size: 100% 100%;
    background-size: 100% 100%;
}

So, now you have a jumbotron with responsive background in place. However, as Irvin Zhan already answered, the height of the background still not showing correctly.

One thing you can do is fill your div with some spaces such as this:

<div class="jumbotron">
    <div class="container">
        About
        <br><br><br> <!--keep filling br until the height is to your liking-->
    </div>
</div>

Or, more elegantly, you can set the height of the container. You might want to add another class so that you don't override Bootstrap container class.

<div class="jumbotron">
    <div class="container push-spaces">
        About
    </div>
</div>

.push-spaces
{
    height: 100px;
}

You are probably having a problem with the sort of CSV file that you have.

Open the CSV file with a text editor, check that all the separations are done with the comma, and not semicolon and try the script again. It should work fine.

Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:

json: cannot unmarshal object into Go struct field Comment.author of type string

When pthread_exit() is called, the calling threads stack is no longer addressable as "active" memory for any other thread. The .data, .text and .bss parts of "static" memory allocations are still available to all other threads. Thus, if you need to pass some memory value into pthread_exit() for some other pthread_join() caller to see, it needs to be "available" for the thread calling pthread_join() to use. It should be allocated with malloc()/new, allocated on the pthread_join threads stack, 1) a stack value which the pthread_join caller passed to pthread_create or otherwise made available to the thread calling pthread_exit(), or 2) a static .bss allocated value.

It's vital to understand how memory is managed between a threads stack, and values store in .data/.bss memory sections which are used to store process wide values.

you can get value of checkbox and status by

$('.i-checks').on('ifChanged', function(event) {
    alert('checked = ' + event.target.checked);
    alert('value = ' + event.target.value);
});

'-replace' does a regex search and you have special characters in that last one (like +) So you might use the non-regex replace version like this:

$c = $c.replace('AccountKey=eKkij32jGEIYIEqAR5RjkKgf4OTiMO6SAyF68HsR/Zd/KXoKvSdjlUiiWyVV2+OUFOrVsd7jrzhldJPmfBBpQA==','DdOegAhDmLdsou6Ms6nPtP37bdw6EcXucuT47lf9kfClA6PjGTe3CfN+WVBJNWzqcQpWtZf10tgFhKrnN48lXA==')

Open with append:

pFile2 = fopen("myfile2.txt", "a");

then just write to pFile2, no need to fseek().

This warning is about unsafe use of strcpy. Try IOBname[ii]='\0'; instead.

When you have everything #included, an unresolved external symbol is often a missing * or & in the declaration or definition of a function.

The request is printed in a request.txt with details

$ch = curl_init();
$f = fopen('request.txt', 'w');
curl_setopt_array($ch, array(
CURLOPT_URL            => $url, 
CURLOPT_RETURNTRANSFER => 1,
CURLOPT_FOLLOWLOCATION => 1,
CURLOPT_VERBOSE        => 1,
CURLOPT_STDERR         => $f,
));
$response = curl_exec($ch);
fclose($f);
curl_close($ch);

You can also use curl_getinfo() function.

Its blank because you are writing to file. you should write to output using php://output instead and also send header information to indicate that it's csv.

Example

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');
$data = array(
        'aaa,bbb,ccc,dddd',
        '123,456,789',
        '"aaa","bbb"'
);

$fp = fopen('php://output', 'wb');
foreach ( $data as $line ) {
    $val = explode(",", $line);
    fputcsv($fp, $val);
}
fclose($fp);

Create a class TestUserDetailsImpl on your test package:

@Service
@Primary
@Profile("test")
public class TestUserDetailsImpl implements UserDetailsService {
    public static final String API_USER = "[email protected]";

    private User getAdminUser() {
        User user = new User();
        user.setUsername(API_USER);

        SimpleGrantedAuthority role = new SimpleGrantedAuthority("ROLE_API_USER");
        user.setAuthorities(Collections.singletonList(role));

        return user;
    }

    @Override
    public UserDetails loadUserByUsername(String username) 
                                         throws UsernameNotFoundException {
        if (Objects.equals(username, ADMIN_USERNAME))
            return getAdminUser();
        throw new UsernameNotFoundException(username);
    }
}

Rest endpoint:

@GetMapping("/invoice")
@Secured("ROLE_API_USER")
public Page<InvoiceDTO> getInvoices(){
   ...
}

Test endpoint:

@Test
@WithUserDetails("[email protected]")
public void testApi() throws Exception {
     ...
}

An easy way I'm using:

file_put_contents($output_file, file_get_contents($base64_string));

This works well because file_get_contents can read data from a URI, including a data:// URI.

You append a newline to both the username and the password, i.e. the output would be something like

Sebastian
password
John
hfsjaijn

use fwrite($fh,$user." ".$password."\n"); instead to have them both on one line.
Or use fputcsv() to write the data and fgetcsv() to fetch it. This way you would at least avoid encoding problems like e.g. with $username='Charles, III';

...i.e. setting aside all the things that are wrong about storing plain passwords in plain files and using _GET for this type of operation (use _POST instead) ;-)

use fwrite() instead of file_put_contents()

I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:

1) I set up a form so I can use a POST method.

2) When the user is done drawing, he can click the "Save" button.

3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.

document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();

4) When the form is submited I have this small php script:

<?php 
$upload_dir = somehow_get_upload_dir();  //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>

This is a simple solution that exports an array to csv string:

function array2csv($data, $delimiter = ',', $enclosure = '"', $escape_char = "\\")
{
    $f = fopen('php://memory', 'r+');
    foreach ($data as $item) {
        fputcsv($f, $item, $delimiter, $enclosure, $escape_char);
    }
    rewind($f);
    return stream_get_contents($f);
}

$list = array (
    array('aaa', 'bbb', 'ccc', 'dddd'),
    array('123', '456', '789'),
    array('"aaa"', '"bbb"')
);
var_dump(array2csv($list));

near the end of the parser function you missed a '}'

What system are you running on? Do you have access to some sort of debugger (gdb, visual studio's debugger, etc.)?

That would give us valuable information, like the line of code where the program crashes... Also, the amount of memory may be prohibitive.

Additionally, may I recommend that you replace the numeric limits by named definitions?

As such:

#define DIM1_SZ 1000
#define DIM2_SZ 1000000

Use those whenever you wish to refer to the array dimension limits. It will help avoid typing errors.

You have a ; at the end of the if. Change:

  if (fp == NULL);
  return 0;

to

  if (fp == NULL) 
    return 0;

Thanks to your comments. I've made a function that give an error message when it happens:

/**
 * Replaces a string in a file
 *
 * @param string $FilePath
 * @param string $OldText text to be replaced
 * @param string $NewText new text
 * @return array $Result status (success | error) & message (file exist, file permissions)
 */
function replace_in_file($FilePath, $OldText, $NewText)
{
    $Result = array('status' => 'error', 'message' => '');
    if(file_exists($FilePath)===TRUE)
    {
        if(is_writeable($FilePath))
        {
            try
            {
                $FileContent = file_get_contents($FilePath);
                $FileContent = str_replace($OldText, $NewText, $FileContent);
                if(file_put_contents($FilePath, $FileContent) > 0)
                {
                    $Result["status"] = 'success';
                }
                else
                {
                   $Result["message"] = 'Error while writing file';
                }
            }
            catch(Exception $e)
            {
                $Result["message"] = 'Error : '.$e;
            }
        }
        else
        {
            $Result["message"] = 'File '.$FilePath.' is not writable !';
        }
    }
    else
    {
        $Result["message"] = 'File '.$FilePath.' does not exist !';

I answered a virtually identical question just the other day: Save CSV files into mysql database

MySQL has a feature LOAD DATA INFILE, which allows it to import a CSV file directly in a single SQL query, without needing it to be processed in a loop via your PHP program at all.

Simple example:

<?php
$query = <<<eof
    LOAD DATA INFILE '$fileName'
     INTO TABLE tableName
     FIELDS TERMINATED BY '|' OPTIONALLY ENCLOSED BY '"'
     LINES TERMINATED BY '\n'
    (field1,field2,field3,etc)
eof;

$db->query($query);
?>

It's as simple as that.

No loops, no fuss. And much much quicker than parsing it in PHP.

MySQL manual page here: http://dev.mysql.com/doc/refman/5.1/en/load-data.html

Hope that helps

You are missing an include : #include <stdlib.h>, so GCC creates an implicit declaration of atof and atod, leading to garbage values.

And the format specifier for double is %f, not %d (that is for integers).

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

int main()
{
  char *test = "12.11";
  double temp = strtod(test,NULL);
  float ftemp = atof(test);
  printf("price: %f, %f",temp,ftemp);
  return 0;
}
/* Output */
price: 12.110000, 12.110000

here is another solution...

System.IO.Stream st = new System.IO.StreamReader (picturePath).BaseStream;
byte[] buffer = new byte[4096];

System.IO.MemoryStream m = new System.IO.MemoryStream ();
while (st.Read (buffer,0,buffer.Length) > 0) {
    m.Write (buffer, 0, buffer.Length);
}  
imgView.Tag = m.ToArray ();
st.Close ();
m.Close ();

hope it helps!

This is a firewall issue, if you are using a VMware application, make sure the firewall on the antivirus is turned off or allowing connections.

Qt has a method for copying files:

#include <QFile>
QFile::copy("originalFile.example","copiedFile.example");

Note that to use this you have to install Qt (instructions here) and include it in your project (if you're using Windows and you're not an administrator, you can download Qt here instead). Also see this answer.

<div id="sample"></div>   
 <form>
        <fieldset>
            <legend>Add New Contact</legend>
            <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
            <input type="email" name="email" placeholder="[email protected]" required /> <br />
            <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
            <input type="submit" name="submit" id= "submitButton" class="button" value="Add Contact" onClick="" />
            <input type="button" name="cancel" class="button" value="Reset" />
        </fieldset>
    </form>

<script>

    $(document).ready(function(){
         $("#submitButton").click(function(){
            $("#sample").load(filenameofyourfunction?the the variable you need);
         });
    });

If fptr is NULL, then you don't have an open file. Therefore, you can't freopen it, you should just fopen it.

FILE *fptr;
fptr = fopen("scores.dat", "rb+");
if(fptr == NULL) //if file does not exist, create it
{
    fptr = fopen("scores.dat", "wb");
}

note: Since the behavior of your program varies depending on whether the file is opened in read or write modes, you most probably also need to keep a variable indicating which is the case.

A complete example

int main()
{
    FILE *fptr;
    char there_was_error = 0;
    char opened_in_read  = 1;
    fptr = fopen("scores.dat", "rb+");
    if(fptr == NULL) //if file does not exist, create it
    {
        opened_in_read = 0;
        fptr = fopen("scores.dat", "wb");
        if (fptr == NULL)
            there_was_error = 1;
    }
    if (there_was_error)
    {
        printf("Disc full or no permission\n");
        return EXIT_FAILURE;
    }
    if (opened_in_read)
        printf("The file is opened in read mode."
               " Let's read some cached data\n");
    else
        printf("The file is opened in write mode."
               " Let's do some processing and cache the results\n");
    return EXIT_SUCCESS;
}

for (int i = 1; i < argc; i++) {

    if (strcmp(argv[i],"-i")==0) {
        filename = argv[i+1];
        printf("filename: %s",filename);
    } else if (strcmp(argv[i],"-c")==0) {
        convergence = atoi(argv[i + 1]);
        printf("\nconvergence: %d",convergence);
    } else if (strcmp(argv[i],"-a")==0) {
        accuracy = atoi(argv[i + 1]);
        printf("\naccuracy:%d",accuracy);
    } else if (strcmp(argv[i],"-t")==0) {
        targetBitRate = atof(argv[i + 1]);
        printf("\ntargetBitRate:%f",targetBitRate);
    } else if (strcmp(argv[i],"-f")==0) {
        frameRate = atoi(argv[i + 1]);
        printf("\nframeRate:%d",frameRate);
    }

}

If you are running PHP on Apache then you can use the enviroment variable called DOCUMENT_ROOT. This means that the path is dynamic, and can be moved between servers without messing about with the code.

<?php
  $fileLocation = getenv("DOCUMENT_ROOT") . "/myfile.txt";
  $file = fopen($fileLocation,"w");
  $content = "Your text here";
  fwrite($file,$content);
  fclose($file);
?>

JavaScript, as defined in your question, can't directly work with MySql. This is because it isn't running on the same computer.

JavaScript runs on the client side (in the browser), and databases usually exist on the server side. You'll probably need to use an intermediate server-side language (like PHP, Java, .Net, or a server-side JavaScript stack like Node.js) to do the query.

Here's a tutorial on how to write some code that would bind PHP, JavaScript, and MySql together, with code running both in the browser, and on a server:

http://www.w3schools.com/php/php_ajax_database.asp

And here's the code from that page. It doesn't exactly match your scenario (it does a query, and doesn't store data in the DB), but it might help you start to understand the types of interactions you'll need in order to make this work.

In particular, pay attention to these bits of code from that article.

Bits of Javascript:

xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();

Bits of PHP code:

mysql_select_db("ajax_demo", $con);
$result = mysql_query($sql);
// ...
$row = mysql_fetch_array($result)
mysql_close($con);

Also, after you get a handle on how this sort of code works, I suggest you use the jQuery JavaScript library to do your AJAX calls. It is much cleaner and easier to deal with than the built-in AJAX support, and you won't have to write browser-specific code, as jQuery has cross-browser support built in. Here's the page for the jQuery AJAX API documentation.

The code from the article

HTML/Javascript code:

<html>
<head>
<script type="text/javascript">

{
if (str=="")
  {
  document.getElementById("txtHint").innerHTML="";

  } 
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("txtHint").innerHTML=xmlhttp.responseText;
    }
  }
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
</script>

$result = mysql_query($sql);

echo "<table border='1'>

[function.fopen]: failed to open stream

If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :

allow_url_fopen = off
should bee this 
allow_url_fopen = On

And add this line below it:
allow_url_include = off
should bee this 
allow_url_include = on

If you want to download an image from https:

$output_filename = 'output.png';
$host = "https://.../source.png"; // <-- Source image url (FIX THIS)
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $host);
curl_setopt($ch, CURLOPT_VERBOSE, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_AUTOREFERER, false);
curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); // <-- don't forget this
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0); // <-- and this
$result = curl_exec($ch);
curl_close($ch);
$fp = fopen($output_filename, 'wb');
fwrite($fp, $result);
fclose($fp);

If you want to change the permissions of an existing file, use chmod (change mode):

$itWorked = chmod ("/yourdir/yourfile", 0777);

If you want all new files to have certain permissions, you need to look into setting your umode. This is a process setting that applies a default modification to standard modes.

It is a subtractive one. By that, I mean a umode of 022 will give you a default permission of 755 (777 - 022 = 755).

But you should think very carefully about both these options. Files created with that mode will be totally unprotected from changes.

when curl is used to download a large file then CURLOPT_TIMEOUT is the main option you have to set for.

CURLOPT_RETURNTRANSFER has to be true in case you are getting file like pdf/csv/image etc.

You may find the further detail over here(correct url) Curl Doc

From that page:

curl_setopt($request, CURLOPT_TIMEOUT, 300); //set timeout to 5 mins

curl_setopt($request, CURLOPT_RETURNTRANSFER, true); // true to get the output as string otherwise false

    $file = file("links.txt");
print_r($file);

This will be accept the txt file as array. So write anything to the links.txt file (use one line for one element) after, run this page :) your array will be $file

So, @Vivek has got the solution to the problem through a dialogue in the Comments rather than through an actual answer.

"The file is being created by user oracle just noticed this in our development database. i'm getting this error because, the directory where i try to create the file doesn't have write access for others and user oracle comes under others category. "

Who says SO is a Q&A site not a forum? Er, me, amongst others. Anyway, in the absence of an accepted answer to this question I proffer a link to an answer of mine on the topic of UTL_FILE.FOPEN(). Find it here.

P.S. I'm marking this answer Community Wiki, because it's not a proper answer to this question, just a redirect to somewhere else.

I had this problem "This could be due to the service endpoint binding not using the HTTP protocol" and the WCF service would shut down (in a development machine)

I figured out: in my case, the problem was because of Enums,

I solved using this

    [DataContract]
    [Flags]
    public enum Fruits
    {
        [EnumMember]
        APPLE = 1,
        [EnumMember]
        BALL = 2,
        [EnumMember]
        ORANGE = 3 

    }

I had to decorate my Enums with DataContract, Flags and all each of the enum member with EnumMember attributes.

I solved this after looking at this msdn Reference:

You could try looping until the line you want, not the EOF, and resetting the variable to the line each time (not adding to it). In your case, the 2nd line is the EOF. (A for loop is probably more appropriate in my code below).

This way the entire file is not in the memory; the drawback is it takes time to go through the file up to the point you want.

<?php 
$myFile = "4-24-11.txt";
$fh = fopen($myFile, 'r');
$i = 0;
while ($i < 2)
 {
  $theData = fgets($fh);
  $i++
 }
fclose($fh);
echo $theData;
?>

It's wrong because (in the absence of a read error) it enters the loop one more time than the author expects. If there is a read error, the loop never terminates.

Consider the following code:

/* WARNING: demonstration of bad coding technique!! */

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

FILE *Fopen(const char *path, const char *mode);

int main(int argc, char **argv)
{
    FILE *in;
    unsigned count;

    in = argc > 1 ? Fopen(argv[1], "r") : stdin;
    count = 0;

    /* WARNING: this is a bug */
    while( !feof(in) ) {  /* This is WRONG! */
        fgetc(in);
        count++;
    }
    printf("Number of characters read: %u\n", count);
    return EXIT_SUCCESS;
}

FILE * Fopen(const char *path, const char *mode)
{
    FILE *f = fopen(path, mode);
    if( f == NULL ) {
        perror(path);
        exit(EXIT_FAILURE);
    }
    return f;
}

This program will consistently print one greater than the number of characters in the input stream (assuming no read errors). Consider the case where the input stream is empty:

$ ./a.out < /dev/null
Number of characters read: 1

In this case, feof() is called before any data has been read, so it returns false. The loop is entered, fgetc() is called (and returns EOF), and count is incremented. Then feof() is called and returns true, causing the loop to abort.

This happens in all such cases. feof() does not return true until after a read on the stream encounters the end of file. The purpose of feof() is NOT to check if the next read will reach the end of file. The purpose of feof() is to determine the status of a previous read function and distinguish between an error condition and the end of the data stream. If fread() returns 0, you must use feof/ferror to decide whether an error occurred or if all of the data was consumed. Similarly if fgetc returns EOF. feof() is only useful after fread has returned zero or fgetc has returned EOF. Before that happens, feof() will always return 0.

It is always necessary to check the return value of a read (either an fread(), or an fscanf(), or an fgetc()) before calling feof().

Even worse, consider the case where a read error occurs. In that case, fgetc() returns EOF, feof() returns false, and the loop never terminates. In all cases where while(!feof(p)) is used, there must be at least a check inside the loop for ferror(), or at the very least the while condition should be replaced with while(!feof(p) && !ferror(p)) or there is a very real possibility of an infinite loop, probably spewing all sorts of garbage as invalid data is being processed.

So, in summary, although I cannot state with certainty that there is never a situation in which it may be semantically correct to write "while(!feof(f))" (although there must be another check inside the loop with a break to avoid a infinite loop on a read error), it is the case that it is almost certainly always wrong. And even if a case ever arose where it would be correct, it is so idiomatically wrong that it would not be the right way to write the code. Anyone seeing that code should immediately hesitate and say, "that's a bug". And possibly slap the author (unless the author is your boss in which case discretion is advised.)

Here, try this (assuming it's a small file!):

<?php
echo file_get_contents( "filename.php" ); // get the contents, and echo it out.
?>

Windows Character Encoding Issue

I was having the same issue. I was editing files in PDT Eclipse on Windows and WinSCPing them over. I just copied and pasted the contents into a nano window, saved, and now they worked. Definitely some Windows character encoding issue, and not a matter of Shebangs or interpreter flags.

None of the previous answers are complete and most contain misinformation.

There are three ways of accessing the attributes of a DOM Element in JavaScript. All three work reliably in modern browsers as long as you understand how to utilize them.

1. element.attributes

Elements have a property attributes that returns a live NamedNodeMap of Attr objects. The indexes of this collection may be different among browsers. So, the order is not guaranteed. NamedNodeMap has methods for adding and removing attributes (getNamedItem and setNamedItem, respectively).

Notice that though XML is explicitly case sensitive, the DOM spec calls for string names to be normalized, so names passed to getNamedItem are effectively case insensitive.

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//you can look up specific attributes_x000D_
var classAttr = div.attributes.getNamedItem('CLASS');_x000D_
document.write('attributes.getNamedItem() Name: ' + classAttr.name + ' Value: ' + classAttr.value + '<br>');_x000D_
_x000D_
//you can enumerate all defined attributes_x000D_
for(var i = 0; i < div.attributes.length; i++) {_x000D_
  var attr = div.attributes[i];_x000D_
  document.write('attributes[] Name: ' + attr.name + ' Value: ' + attr.value + '<br>');_x000D_
}_x000D_
_x000D_
//create custom attribute_x000D_
var customAttr = document.createAttribute('customTest');_x000D_
customAttr.value = '567';_x000D_
div.attributes.setNamedItem(customAttr);_x000D_
_x000D_
//retreive custom attribute_x000D_
customAttr = div.attributes.getNamedItem('customTest');_x000D_
document.write('attributes.getNamedItem() Name: ' + customAttr.name + ' Value: ' + customAttr.value + '<br>');

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

2. element.getAttribute & element.setAttribute

These methods exist directly on the Element without needing to access attributes and its methods but perform the same functions.

Again, notice that string name are case insensitive.

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//get specific attributes_x000D_
document.write('Name: class Value: ' + div.getAttribute('class') + '<br>');_x000D_
document.write('Name: ID Value: ' + div.getAttribute('ID') + '<br>');_x000D_
document.write('Name: DATA-TEST Value: ' + div.getAttribute('DATA-TEST') + '<br>');_x000D_
document.write('Name: nonStandard Value: ' + div.getAttribute('nonStandard') + '<br>');_x000D_
_x000D_
_x000D_
//create custom attribute_x000D_
div.setAttribute('customTest', '567');_x000D_
_x000D_
//retreive custom attribute_x000D_
document.write('Name: customTest Value: ' + div.getAttribute('customTest') + '<br>');

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

3. Properties on the DOM object, such as element.id

Many attributes can be accessed using convenient properties on the DOM object. Which attributes exist depends on the DOM node's type, not which attributes are defined in the HTML. The properties are defined somewhere in the prototype chain of DOM object in question. The specific properties defined will depend on the type of Element you are accessing. For example, className and id are defined on Element and exist on all DOM nodes that are elements (ie. not text or comment nodes). But value is more narrow. It's defined on HTMLInputElement and may not exist on other elements.

Notice that JavaScript properties are case sensitive. Although most properties will use lowercase, some are camelCase. So always check the spec to be sure.

This "chart" captures a portion of the prototype chain for these DOM objects. It's not even close to complete, but it captures the overall structure.

                      ____________Node___________
                      |               |         |
                   Element           Text   Comment
                   |     |
           HTMLElement   SVGElement
           |         |
HTMLInputElement   HTMLSpanElement

Example Usage:

var div = document.getElementsByTagName('div')[0];_x000D_
_x000D_
//get specific attributes_x000D_
document.write('Name: class Value: ' + div.className + '<br>');_x000D_
document.write('Name: id Value: ' + div.id + '<br>');_x000D_
document.write('Name: ID Value: ' + div.ID + '<br>'); //undefined_x000D_
document.write('Name: data-test Value: ' + div.dataset.test + '<br>'); //.dataset is a special case_x000D_
document.write('Name: nonStandard Value: ' + div.nonStandard + '<br>'); //undefined

<div class="class1" id="main" data-test="stuff" nonStandard="1234"></div>

Caveat: This is an explanation of how the HTML spec defines and modern browsers handle attributes. I did not attempt to deal with limitations of ancient, broken browsers. If you need to support old browsers, in addition to this information, you will need to know what is broken in the those browsers.

You could read the entire file with dynamic memory allocation, but isn't a good idea because if the file is too big, you could have memory problems.

So is better read short parts of the file and print it.

#include <stdio.h>
#define BLOCK   1000

int main() {
    FILE *f=fopen("teste.txt","r");
    int size;
    char buffer[BLOCK];
    // ...
    while((size=fread(buffer,BLOCK,sizeof(char),f)>0)
            fwrite(buffer,size,sizeof(char),stdout);
    fclose(f);
    // ...
    return 0;
}

Use PHP_EOL which outputs \r\n or \n depending on the OS.

You can use:

var queryString = url.Substring(url.IndexOf('?')).Split('#')[0]
System.Web.HttpUtility.ParseQueryString(queryString)

MSDN

The directory name seems to be case sensitive. I faced the same issue but when I provided the directory name in upper case it worked.

You cannot open a connection directly to a path on a remote host using fsockopen. The url www.mydomain.net/1/file.php contains a path, when the only valid value for that first parameter is the host, www.mydomain.net.

If you are trying to access a remote URL, then file_get_contents() is your best bet. You can provide a full URL to that function, and it will fetch the content at that location using a normal HTTP request.

If you only want to send an HTTP request and ignore the response, you could use fsockopen() and manually send the HTTP request headers, ignoring any response. It might be easier with cURL though, or just plain old fopen(), which will open the connection but not necessarily read any response. If you wanted to do it with fsockopen(), it might look something like this:

$fp = fsockopen("www.mydomain.net", 80, $errno, $errstr, 30);
fputs($fp, "GET /1/file.php HTTP/1.1\n");
fputs($fp, "Host: www.mydomain.net\n");
fputs($fp, "Connection: close\n\n"); 

That leaves any error handling up to you of course, but it would mean that you wouldn't waste time reading the response.

char source[1000000];

FILE *fp = fopen("TheFile.txt", "r");
if(fp != NULL)
{
    while((symbol = getc(fp)) != EOF)
    {
        strcat(source, &symbol);
    }
    fclose(fp);
}

There are quite a few things wrong with this code:

1. It is very slow (you are extracting the buffer one character at a time).
2. If the filesize is over sizeof(source), this is prone to buffer overflows.
3. Really, when you look at it more closely, this code should not work at all. As stated in the man pages:

The strcat() function appends a copy of the null-terminated string s2 to the end of the null-terminated string s1, then add a terminating `\0'.

You are appending a character (not a NUL-terminated string!) to a string that may or may not be NUL-terminated. The only time I can imagine this working according to the man-page description is if every character in the file is NUL-terminated, in which case this would be rather pointless. So yes, this is most definitely a terrible abuse of strcat().

The following are two alternatives to consider using instead.

If you know the maximum buffer size ahead of time:

#include <stdio.h>
#define MAXBUFLEN 1000000

char source[MAXBUFLEN + 1];
FILE *fp = fopen("foo.txt", "r");
if (fp != NULL) {
    size_t newLen = fread(source, sizeof(char), MAXBUFLEN, fp);
    if ( ferror( fp ) != 0 ) {
        fputs("Error reading file", stderr);
    } else {
        source[newLen++] = '\0'; /* Just to be safe. */
    }

    fclose(fp);
}

Or, if you do not:

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

char *source = NULL;
FILE *fp = fopen("foo.txt", "r");
if (fp != NULL) {
    /* Go to the end of the file. */
    if (fseek(fp, 0L, SEEK_END) == 0) {
        /* Get the size of the file. */
        long bufsize = ftell(fp);
        if (bufsize == -1) { /* Error */ }

        /* Allocate our buffer to that size. */
        source = malloc(sizeof(char) * (bufsize + 1));

        /* Go back to the start of the file. */
        if (fseek(fp, 0L, SEEK_SET) != 0) { /* Error */ }

        /* Read the entire file into memory. */
        size_t newLen = fread(source, sizeof(char), bufsize, fp);
        if ( ferror( fp ) != 0 ) {
            fputs("Error reading file", stderr);
        } else {
            source[newLen++] = '\0'; /* Just to be safe. */
        }
    }
    fclose(fp);
}

free(source); /* Don't forget to call free() later! */

Here are the steps:

1. Open the file
2. Write to the file

3. Close the file

   $select = "data what we trying to store in a file";
   $file = fopen("/var/www/htdocs/folder/test.txt", "w");        
   fwrite($file, $select->__toString());
   fclose($file);
   

Your executable's working directory is probably set to something other than the directory where it is saved. Check your IDE settings.

The answer to your question is that the newer SQLite 3 has improved performance, use that.

This answer Why is SQLAlchemy insert with sqlite 25 times slower than using sqlite3 directly? by SqlAlchemy Orm Author has 100k inserts in 0.5 sec, and I have seen similar results with python-sqlite and SqlAlchemy. Which leads me to believe that performance has improved with SQLite 3.

You can force gcc to output directly to assembly code by adding the -S switch

gcc -S hello.c

Let's start with a simple example. Let's say you have an email list, that is going to send out the following RFC2822 content.

From: <[email protected]>
To: <[email protected]>
Subject: Super simple email
Reply-To: <[email protected]>

This is a very simple body.

Now, let's say you are going to send it from a mailing list, that implements VERP (or some other bounce tracking mechanism that uses a different return-path). Lets say it will have a return-path of [email protected]. The SMTP session might look like:

{S}220 workstation1 Microsoft ESMTP MAIL Service
{C}HELO workstation1
{S}250 workstation1 Hello [127.0.0.1]
{C}MAIL FROM:<[email protected]>
{S}250 2.1.0 [email protected] OK
{C}RCPT TO:<[email protected]>
{S}250 2.1.5 [email protected] 
{C}DATA
{S}354 Start mail input; end with <CRLF>.<CRLF>
{C}From: <[email protected]>
To: <[email protected]>
Subject: Super simple email
Reply-To: <[email protected]>

This is a very simple body.
.

{S}250 Queued mail for delivery
{C}QUIT
{S}221 Service closing transmission channel

Where {C} and {S} represent Client and Server commands, respectively.

The recipient's mail would look like:

Return-Path: [email protected]
From: <[email protected]>
To: <[email protected]>
Subject: Super simple email
Reply-To: <[email protected]>

This is a very simple body.

Now, let's describe the different "FROM"s.

1. The return path (sometimes called the reverse path, envelope sender, or envelope from — all of these terms can be used interchangeably) is the value used in the SMTP session in the MAIL FROM command. As you can see, this does not need to be the same value that is found in the message headers. Only the recipient's mail server is supposed to add a Return-Path header to the top of the email. This records the actual Return-Path sender during the SMTP session. If a Return-Path header already exists in the message, then that header is removed and replaced by the recipient's mail server.

All bounces that occur during the SMTP session should go back to the Return-Path address. Some servers may accept all email, and then queue it locally, until it has a free thread to deliver it to the recipient's mailbox. If the recipient doesn't exist, it should bounce it back to the recorded Return-Path value.

Note, not all mail servers obey this rule; Some mail servers will bounce it back to the FROM address.

2. The FROM address is the value found in the FROM header. This is supposed to be who the message is FROM. This is what you see as the "FROM" in most mail clients. If an email does not have a Reply-To header, then all human (mail client) replies should go back to the FROM address.

3. The Reply-To header is added by the sender (or the sender's software). It is where all human replies should be addressed too. Basically, when the user clicks "reply", the Reply-To value should be the value used as the recipient of the newly composed email. The Reply-To value should not be used by any server. It is meant for client-side (MUA) use only.

However, as you can tell, not all mail servers obey the RFC standards or recommendations.

Hopefully this should help clear things up. However, if I missed anything, let me know, and I'll try to answer.

This is not an answer to your original question, but a better way of doing what you're trying to do:

Instead of actually trying to get the site's favicon directly (which is a royal pain given it could be /favicon.png, /favicon.ico, /favicon.gif, or even /path/to/favicon.png), use google:

<img src="http://www.google.com/s2/favicons?domain=[domain]">

Done.

if ([linkedStr isEqual:(id)[NSNull null]])
                {
                    _linkedinLbl.text=@"No";
                }else{
                    _linkedinLbl.text=@"Yes";
                }

Acoording to RFC 2046 (Multipurpose Internet Mail Extensions):

The recommended action for an implementation that receives an
"application/octet-stream" entity is to simply offer to put the data in a file

So I'd go for that one.

FILE *file;
    if((file = fopen("sample.txt","r"))!=NULL)
        {
            // file exists
            fclose(file);
        }
    else
        {
            //File not found, no memory leak since 'file' == NULL
            //fclose(file) would cause an error
        }

It turns out the compiler version I was using did not match the compiled version done with the coreset.o.

One was 32bit the other was 64bit. I'll leave this up in case anyone else runs into a similar problem.

Most probably you won't be able to read Word documents without COM.

Writing was covered in this topic

Introducing: a very generalized solution for PHP 5.3+

I 'd like to add my own solution here, since it offers features that other answers do not.

Specifically, advantages of this solution include:

1. It's reusable: you specify the sort column as a variable instead of hardcoding it.
2. It's flexible: you can specify multiple sort columns (as many as you want) -- additional columns are used as tiebreakers between items that initially compare equal.
3. It's reversible: you can specify that the sort should be reversed -- individually for each column.
4. It's extensible: if the data set contains columns that cannot be compared in a "dumb" manner (e.g. date strings) you can also specify how to convert these items to a value that can be directly compared (e.g. a DateTime instance).
5. It's associative if you want: this code takes care of sorting items, but you select the actual sort function (usort or uasort).
6. Finally, it does not use array_multisort: while array_multisort is convenient, it depends on creating a projection of all your input data before sorting. This consumes time and memory and may be simply prohibitive if your data set is large.

The code

function make_comparer() {
    // Normalize criteria up front so that the comparer finds everything tidy
    $criteria = func_get_args();
    foreach ($criteria as $index => $criterion) {
        $criteria[$index] = is_array($criterion)
            ? array_pad($criterion, 3, null)
            : array($criterion, SORT_ASC, null);
    }

    return function($first, $second) use (&$criteria) {
        foreach ($criteria as $criterion) {
            // How will we compare this round?
            list($column, $sortOrder, $projection) = $criterion;
            $sortOrder = $sortOrder === SORT_DESC ? -1 : 1;

            // If a projection was defined project the values now
            if ($projection) {
                $lhs = call_user_func($projection, $first[$column]);
                $rhs = call_user_func($projection, $second[$column]);
            }
            else {
                $lhs = $first[$column];
                $rhs = $second[$column];
            }

            // Do the actual comparison; do not return if equal
            if ($lhs < $rhs) {
                return -1 * $sortOrder;
            }
            else if ($lhs > $rhs) {
                return 1 * $sortOrder;
            }
        }

        return 0; // tiebreakers exhausted, so $first == $second
    };
}

How to use

Throughout this section I will provide links that sort this sample data set:

$data = array(
    array('zz', 'name' => 'Jack', 'number' => 22, 'birthday' => '12/03/1980'),
    array('xx', 'name' => 'Adam', 'number' => 16, 'birthday' => '01/12/1979'),
    array('aa', 'name' => 'Paul', 'number' => 16, 'birthday' => '03/11/1987'),
    array('cc', 'name' => 'Helen', 'number' => 44, 'birthday' => '24/06/1967'),
);

The basics

The function make_comparer accepts a variable number of arguments that define the desired sort and returns a function that you are supposed to use as the argument to usort or uasort.

The simplest use case is to pass in the key that you 'd like to use to compare data items. For example, to sort $data by the name item you would do

usort($data, make_comparer('name'));

See it in action.

The key can also be a number if the items are numerically indexed arrays. For the example in the question, this would be

usort($data, make_comparer(0)); // 0 = first numerically indexed column

See it in action.

Multiple sort columns

You can specify multiple sort columns by passing additional parameters to make_comparer. For example, to sort by "number" and then by the zero-indexed column:

usort($data, make_comparer('number', 0));

See it in action.

Advanced features

More advanced features are available if you specify a sort column as an array instead of a simple string. This array should be numerically indexed, and must contain these items:

0 => the column name to sort on (mandatory)
1 => either SORT_ASC or SORT_DESC (optional)
2 => a projection function (optional)

Let's see how we can use these features.

Reverse sort

To sort by name descending:

usort($data, make_comparer(['name', SORT_DESC]));

See it in action.

To sort by number descending and then by name descending:

usort($data, make_comparer(['number', SORT_DESC], ['name', SORT_DESC]));

See it in action.

Custom projections

In some scenarios you may need to sort by a column whose values do not lend well to sorting. The "birthday" column in the sample data set fits this description: it does not make sense to compare birthdays as strings (because e.g. "01/01/1980" comes before "10/10/1970"). In this case we want to specify how to project the actual data to a form that can be compared directly with the desired semantics.

Projections can be specified as any type of callable: as strings, arrays, or anonymous functions. A projection is assumed to accept one argument and return its projected form.

It should be noted that while projections are similar to the custom comparison functions used with usort and family, they are simpler (you only need to convert one value to another) and take advantage of all the functionality already baked into make_comparer.

Let's sort the example data set without a projection and see what happens:

usort($data, make_comparer('birthday'));

See it in action.

That was not the desired outcome. But we can use date_create as a projection:

usort($data, make_comparer(['birthday', SORT_ASC, 'date_create']));

See it in action.

This is the correct order that we wanted.

There are many more things that projections can achieve. For example, a quick way to get a case-insensitive sort is to use strtolower as a projection.

That said, I should also mention that it's better to not use projections if your data set is large: in that case it would be much faster to project all your data manually up front and then sort without using a projection, although doing so will trade increased memory usage for faster sort speed.

Finally, here is an example that uses all the features: it first sorts by number descending, then by birthday ascending:

usort($data, make_comparer(
    ['number', SORT_DESC],
    ['birthday', SORT_ASC, 'date_create']
));

See it in action.

Just adding to the answers already given, the solution using the string "nunique" seems much faster, tested here on ~21M rows dataframe, then grouped to ~2M

%time _=g.agg({"id": lambda x: x.nunique()})
CPU times: user 3min 3s, sys: 2.94 s, total: 3min 6s
Wall time: 3min 20s

%time _=g.agg({"id": pd.Series.nunique})
CPU times: user 3min 2s, sys: 2.44 s, total: 3min 4s
Wall time: 3min 18s

%time _=g.agg({"id": "nunique"})
CPU times: user 14 s, sys: 4.76 s, total: 18.8 s
Wall time: 24.4 s

if you using Generic Array List with Class instead of specific type like

EX:

private ArrayList<Model> aListModel = new ArrayList<Model>();

Here, Model = Class

Receiving Intent Like :

aListModel = (ArrayList<Model>) getIntent().getSerializableExtra(KEY);

MUST REMEMBER:

Here Model-class must be implemented like: ModelClass implements Serializable

You can simply do this with %w notation in ruby arrays.

array = %w(1 2 3)

It will add the array values 1,2,3 to the arrayand print out the output as ["1", "2", "3"]

Making your own itoa is also easy, try this :

char* itoa(int i, char b[]){
    char const digit[] = "0123456789";
    char* p = b;
    if(i<0){
        *p++ = '-';
        i *= -1;
    }
    int shifter = i;
    do{ //Move to where representation ends
        ++p;
        shifter = shifter/10;
    }while(shifter);
    *p = '\0';
    do{ //Move back, inserting digits as u go
        *--p = digit[i%10];
        i = i/10;
    }while(i);
    return b;
}

or use the standard sprintf() function.

You can format your output in Java as described in below code snippet.

public class TestFormat {

    public static void main(String[] args) {
      long n = 461012;
      System.out.format("%d%n", n);      //  -->  "461012"
      System.out.format("%08d%n", n);    //  -->  "00461012"
      System.out.format("%+8d%n", n);    //  -->  " +461012"
      System.out.format("%,8d%n", n);    // -->  " 461,012"
      System.out.format("%+,8d%n%n", n); //  -->  "+461,012"
   }
}

I resolved this issue by escaping the inner double quotes

projectID=$(cat file.json | jq -r ".resource[] | select(.username==\"$EMAILID\") | .id")

You don't need to write any custom code for this. Starting from the 1.2 version Swift has already had all the methods you need:

• getting string length: count(string);
• checking if string contains substring: contains(string, substring);
• checking if string starts with substring: startsWith(string, substring)
• and etc.

Here's how to do it on Heroku

To force SSL on your dynos but not locally, add to end of your .htaccess in public/:

# Force https on heroku...
# Important fact: X-forwarded-Proto will exist at your heroku dyno but wont locally.
# Hence we want: "if x-forwarded exists && if its not https, then rewrite it":
RewriteCond %{HTTP:X-Forwarded-Proto} .
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

You can test this out on your local machine with:

curl -H"X-Forwarded-Proto: http" http://your-local-sitename-here

That sets the header X-forwarded to the form it will take on heroku.

i.e. it simulates how a heroku dyno will see a request.

You'll get this response on your local machine:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>301 Moved Permanently</title>
</head><body>
<h1>Moved Permanently</h1>
<p>The document has moved <a href="https://tm3.localhost:8080/">here</a>.</p>
</body></html>

That is a redirect. That is what heroku is going to give back to a client if you set the .htaccess as above. But it doesn't happen on your local machine because X-forwarded won't be set (we faked it with curl above to see what was happening).

You need to call setHasOptionsMenu(true) in onCreate().

For backwards compatibility it's better to place this call as late as possible at the end of onCreate() or even later in onActivityCreated() or something like that.

See: https://developer.android.com/reference/android/app/Fragment.html#setHasOptionsMenu(boolean)

Complete answer (since angular 1.4). You need to include de dependency $httpParamSerializer

var res = $resource(serverUrl + 'Token', { }, {
                save: { method: 'POST', headers: { 'Content-Type': 'application/x-www-form-urlencoded' } }
            });

            res.save({ }, $httpParamSerializer({ param1: 'sdsd', param2: 'sdsd' }), function (response) {

            }, function (error) { 

            });

All inputs should be replaced with custom directive that reads a single global variable to toggle readonly status.

// template
<your-input [readonly]="!childmessage"></your-input>

// component value
childmessage = false;

You can easily achieve what you want using the appendix package. Here's a sample file that shows you how. The key is the titletoc option when calling the package. It takes whatever value you've defined in \appendixname and the default value is Appendix.

\documentclass{report}
\usepackage[titletoc]{appendix}
\begin{document}
\tableofcontents

\chapter{Lorem ipsum}
\section{Dolor sit amet}
\begin{appendices}
  \chapter{Consectetur adipiscing elit}
  \chapter{Mauris euismod}
\end{appendices}
\end{document}

The output looks like

$('.modal').on('shown.bs.modal',function(){      //correct here use 'shown.bs.modal' event which comes in bootstrap3
  $(this).find('iframe').attr('src','http://www.google.com')
})

As shown above use 'shown.bs.modal' event which comes in bootstrap 3.

EDIT :-

and just try to open some other url from iframe other than google.com ,it will not allow you to open google.com due to some security threats.

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

 select convert_tz(now(),@@session.time_zone,'+05:30')

replace '+05:30' with desired timezone. see here - https://stackoverflow.com/a/3984412/2359994

to format into desired time format, eg:

 select DATE_FORMAT(convert_tz(now(),@@session.time_zone,'+05:30') ,'%b %d %Y %h:%i:%s %p') 

you will get similar to this -> Dec 17 2014 10:39:56 AM

I think the most complete answer to this is the accepted answer found here:

How to get tkinter working with Ubuntu's default Python 2.7 install?

I figured it out after way too much time spent on this problem, so hopefully I can save someone else the hassle.

I found this old bug report deemed invalid that mentioned the exact problem I was having, I had Tkinter.py, but it couldn't find the module _tkinter: http://bugs.python.org/issue8555

I installed the tk-dev package with apt-get, and rebuilt Python using ./configure, make, and make install in the Python2.7.3 directory. And now my Python2.7 can import Tkinter, yay!

I'm a little miffed that the tk-dev package isn't mentioned at all in the Python installation documentation.... below is another helpful resource on missing modules in Python if, like me, someone should discover they are missing more than _tkinter.

I use this function datetime_to_local_timezone(), which seems overly convoluted but I found no simpler version of a function that converts a datetime instance to the local time zone, as configured in the operating system, with the UTC offset that was in effect at that time:

import time, datetime

def datetime_to_local_timezone(dt):
    epoch = dt.timestamp() # Get POSIX timestamp of the specified datetime.
    st_time = time.localtime(epoch) #  Get struct_time for the timestamp. This will be created using the system's locale and it's time zone information.
    tz = datetime.timezone(datetime.timedelta(seconds = st_time.tm_gmtoff)) # Create a timezone object with the computed offset in the struct_time.

    return dt.astimezone(tz) # Move the datetime instance to the new time zone.

utc = datetime.timezone(datetime.timedelta())
dt1 = datetime.datetime(2009, 7, 10, 18, 44, 59, 193982, utc) # DST was in effect
dt2 = datetime.datetime(2009, 1, 10, 18, 44, 59, 193982, utc) # DST was not in effect

print(dt1)
print(datetime_to_local_timezone(dt1))

print(dt2)
print(datetime_to_local_timezone(dt2))

This example prints four dates. For two moments in time, one in January and one in July 2009, each, it prints the timestamp once in UTC and once in the local time zone. Here, where CET (UTC+01:00) is used in the winter and CEST (UTC+02:00) is used in the summer, it prints the following:

2009-07-10 18:44:59.193982+00:00
2009-07-10 20:44:59.193982+02:00

2009-01-10 18:44:59.193982+00:00
2009-01-10 19:44:59.193982+01:00

Use cin.get() to read the next character.

However, for this problem, it is very inefficient to read a character at a time. Use the istream::read() instead.

int main()
{
   char a[10];
   cin.read(a, sizeof(a));
   for(int i = 0; i < 10; i++)
   {
       if(a[i] == ' ')
          cout<<"It is a space!!!"<<<endl;
   }
   return 0;
}

And use == to check equality, not =.

What about android:textAllCaps?

TextWatcher maritalStatusTextWatcher = new TextWatcher() { @Override public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
        try {
            if (charSequence.length()==0){
                topMaritalStatus.setVisibility(View.GONE);
            }else{
                topMaritalStatus.setVisibility(View.VISIBLE);
            }
        }catch (Exception e){
            e.printStackTrace();
        }
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
};

To call a specific exception such as FileNotFoundException use this format

if (-not (Test-Path $file)) 
{
    throw [System.IO.FileNotFoundException] "$file not found."
}

To throw a general exception use the throw command followed by a string.

throw "Error trying to do a task"

When used inside a catch, you can provide additional information about what triggered the error

Based on (dangerouslySetInnerHTML).

It's a prop that does exactly what you want. However they name it to convey that it should be use with caution

You can eliminate index.php from URL by create .htaccess file in the base directory of your porject, that file its content as

RewriteEngine on
RewriteCond $1 !^(index\.php|assets|images|js|css|uploads|favicon.png)
RewriteCond %(REQUEST_FILENAME) !-f
RewriteCond %(REQUEST_FILENAME) !-d
RewriteRule ^(.*)$ ./index.php/$1 [L]

save that file also your changed in config.php file is right

$config['index_page'] = '';

I wish to run successfully

AST_NODE* Statement(AST_NODE* node)

is missing a semicolon (a major clue was the error message "In function ‘Statement’: ...") and so is line 24,

   return node

(Once you fix those, you will encounter other problems, some of which are mentioned by others here.)

Don't forget about fragmentation. If you have a lot of traffic, your pools can be fragmented and even if you have several MB free, there could be no block larger than 4KB. Check size of largest free block with a query like:

Code from

Try this;

   public String toDate() {
       DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
       Calendar cal = Calendar.getInstance();
       cal.add(Calendar.DATE, -1);

Use tow function to solve it ,Very simple and useful:

HTML:

<input class="int-number" type="text" />
<input class="decimal-number" type="text" />

JQuery:

//Integer Number
$(document).on("input", ".int-number", function (e) {
  this.value = this.value.replace(/[^0-9]/g, '');
});

//Decimal Number
$(document).on("input", ".decimal-number", function (e) {
    this.value = this.value.replace(/[^0-9.]/g, '').replace(/(\..*)\./g, '$1');
});

Try this:

$(document).ready( function () {
  $('#example').dataTable({
    "order": []
  });
});

this will solve your problem.

I had a similar problem and I solved it by setting a static IP on the Android device.

When you add the network on Android, first you enter the SSID and password, then underneath you can open advanced options and set a static IP.

1. Right click on Project Name.
2. Select Properties and click.
3. Then, select Debugging and provide your enough argument into Command Arguments box.

Note:

• Also, check Configuration type and Platform.

After that, Click Apply and OK.

The data.table package has its IDate class and functionalities similar to lubridate or the zoo package. You could do:

dt = data.table(
  Name = c('Joe', 'Amy', 'John'),
  JoiningDate = c('12/31/09', '10/28/09', '05/06/10'),
  AmtPaid = c(1000, 100, 200)
)

require(data.table)
dt[ , JoiningDate := as.IDate(JoiningDate, '%m/%d/%y') ]

These are GCC extensions, not part of any C standard.

Your regex ^[0-9] matches anything beginning with a digit, including strings like "1A". To avoid a partial match, append a $ to the end:

^[0-9]*$

This accepts any number of digits, including none. To accept one or more digits, change the * to +. To accept exactly one digit, just remove the *.

UPDATE: You mixed up the arguments to IsMatch. The pattern should be the second argument, not the first:

if (!System.Text.RegularExpressions.Regex.IsMatch(textbox.Text, "^[0-9]*$"))

CAUTION: In JavaScript, \d is equivalent to [0-9], but in .NET, \d by default matches any Unicode decimal digit, including exotic fare like ? (Myanmar 2) and ? (N'Ko 9). Unless your app is prepared to deal with these characters, stick with [0-9] (or supply the RegexOptions.ECMAScript flag).

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

you can define it like this :

let table = $('.datatable-sales').DataTable({
        processing: true,
        responsive: true,
        serverSide: true,
        ajax: {
            url: "<?php echo site_url("your url"); ?>",
            cache: false,
            type: "POST",
            data: {
                <?php echo your api; ?>,
            }
        }

or like this :

$.get({url: <?php echo json_encode(site_url('your api'))?>, cache: false})

Have a look at help set if you have the help information installed. And then select name,address rather than select * if you really only want those two columns.

1. PYTHONPATH is an environment variable
2. Yes (see https://unix.stackexchange.com/questions/24802/on-which-unix-distributions-is-python-installed-as-part-of-the-default-install)
3. /usr/lib/python2.7 on Ubuntu
4. you shouldn't install packages manually. Instead, use pip. When a package isn't in pip, it usually has a setuptools setup script which will install the package into the proper location (see point 3).
5. if you use pip or setuptools, then you don't need to set PYTHONPATH explicitly

If you look at the instructions for pyopengl, you'll see that they are consistent with points 4 and 5.

In general, a procedure is a sequence of instructions.
A function can be the same, but it usually returns a result.

Add the following lines in bash_profile:

alias startmysql='sudo /usr/local/mysql/support-files/mysql.server start'
alias stopmysql='sudo /usr/local/mysql/support-files/mysql.server stop'

and save the bash_profile.

Now, in the terminal start and stop the mysql server using the following commands:

startmysql //to start mysql server

and

stopmysql //to stop mysql server

window.onload = function() {

In case of MySQL or SQLite the correct keyword is IFNULL (not ISNULL).

 SELECT iar.Description, 
      IFNULL(iai.Quantity,0) as Quantity, 
      IFNULL(iai.Quantity * rpl.RegularPrice,0) as 'Retail', 
      iar.Compliance 
    FROM InventoryAdjustmentReason iar
    LEFT OUTER JOIN InventoryAdjustmentItem iai  on (iar.Id = iai.InventoryAdjustmentReasonId)
    LEFT OUTER JOIN Item i on (i.Id = iai.ItemId)
    LEFT OUTER JOIN ReportPriceLookup rpl on (rpl.SkuNumber = i.SkuNo)
WHERE iar.StoreUse = 'yes'

Another way to use target="_blank" is:

onclick="this.target='_blank'"

Example:

<a href="http://www.url.com" onclick="this.target='_blank'">Your Text<a>

You can use the canvas so you don't have to deal so much with css properties:

var canvas = document.createElement("canvas");
var ctx = canvas.getContext("2d");
ctx.font = "20pt Arial";  // This can be set programmaticly from the element's font-style if desired
var textWidth = ctx.measureText($("#myElement").text()).width;

An advance approach is using Kotlin Extension function

fun Context.getRawInput(@RawRes resourceId: Int): InputStream {
    return resources.openRawResource(resourceId)
}

One more interesting thing is extension function use that is defined in Closeable scope

For example you can work with input stream in elegant way without handling Exceptions and memory managing

fun Context.readRaw(@RawRes resourceId: Int): String {
    return resources.openRawResource(resourceId).bufferedReader(Charsets.UTF_8).use { it.readText() }
}

You can use native JS to test for the existence of an object:

if (document.getElementById('elemId') instanceof Object){
    // do something here
}

Don't forget, jQuery is nothing more than a sophisticated (and very useful) wrapper around native Javascript commands and properties

I have resolved the said

MqttException (0) - javax.net.ssl.SSLHandshakeException: No subjectAltNames on the certificate match

error by adding one (can add multiple) alternative subject name in the server certificate (having CN=example.com) which after prints the part of certificate as below:

Subject Alternative Name:
DNS: example.com

I used KeyExplorer on windows for generating my server certificate. You can follow this link for adding alternative subject names (follow the only part for adding it).

If you change your html code a bit - remove the ids

<ul id='myid'>  
<li>First</li>
<li>Second</li>
<li>Third</li>
<li>Fourth</li>
<li>Fifth</li>
</ul>

Then the jquery code you want is...

$("#myid li").click(function() {
    alert($(this).prevAll().length+1);
});?

You don't need to place any ids, just keep on adding li items.

Take a look at demo

Android's Java API does not support javax.naming.* and many other javax.* stuff. You need to include the dependencies as separate jars.

This is an ancient question, but both module private (one underscore) and class-private (two underscores) mangled variables are now covered in the standard documentation:

The Python Tutorial » Classes » Private Variables

flup's answer is the best but it did not work for me completely. I had to do the following as well to get it working:

1. export JAVA_HOME=/usr/lib/jvm/java-7-oracle/jre/
2. chmod 777 on the folder
3. ./gradlew build - Building Hibernate

byte[] bytes = new byte[100];

Initializes all byte elements with default values, which for byte is 0. In fact, all elements of an array when constructed, are initialized with default values for the array element's type.

Try this...

I have used following code to read "xls and xlsx"

    <?php
    include 'excel_reader.php';       // include the class
    $excel = new PhpExcelReader;      // creates object instance of the class
    $excel->read('excel_file.xls');   // reads and stores the excel file data

    // Test to see the excel data stored in $sheets property
    echo '<pre>';
    var_export($excel->sheets);

    echo '</pre>';

    or 

 echo '<pre>';
    print_r($excel->sheets);

    echo '</pre>';

Reference:http://coursesweb.net/php-mysql/read-excel-file-data-php_pc

I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60 returns nothing. The command find . -mmin -60 |xargs ls -l, however, returns every file in the directory which is consistent with what happens when ls -l is run without an argument.

To make sure that ls -l is only run when a file is found, try:

find . -mmin -60 -type f -exec ls -l {} +

1. Writing JSON Parser Class

   public class JSONParser {
   
       static InputStream is = null;
       static JSONObject jObj = null;
       static String json = "";
   
       // constructor
       public JSONParser() {}
   
       public JSONObject getJSONFromUrl(String url) {
   
           // Making HTTP request
           try {
               // defaultHttpClient
               DefaultHttpClient httpClient = new DefaultHttpClient();
               HttpPost httpPost = new HttpPost(url);
   
               HttpResponse httpResponse = httpClient.execute(httpPost);
               HttpEntity httpEntity = httpResponse.getEntity();
               is = httpEntity.getContent();
   
           } catch (UnsupportedEncodingException e) {
               e.printStackTrace();
           } catch (ClientProtocolException e) {
               e.printStackTrace();
           } catch (IOException e) {
               e.printStackTrace();
           }
   
           try {
               BufferedReader reader = new BufferedReader(new InputStreamReader(
                       is, "iso-8859-1"), 8);
               StringBuilder sb = new StringBuilder();
               String line = null;
               while ((line = reader.readLine()) != null) {
                   sb.append(line + "\n");
               }
               is.close();
               json = sb.toString();
           } catch (Exception e) {
               Log.e("Buffer Error", "Error converting result " + e.toString());
           }
   
           // try parse the string to a JSON object
           try {
               jObj = new JSONObject(json);
           } catch (JSONException e) {
               Log.e("JSON Parser", "Error parsing data " + e.toString());
           }
   
           // return JSON String
           return jObj;
   
       }
   }
   

2. Parsing JSON Data
   Once you created parser class next thing is to know how to use that class. Below i am explaining how to parse the json (taken in this example) using the parser class.

   2.1. Store all these node names in variables: In the contacts json we have items like name, email, address, gender and phone numbers. So first thing is to store all these node names in variables. Open your main activity class and declare store all node names in static variables.

   // url to make request
   private static String url = "http://api.9android.net/contacts";
   
   // JSON Node names
   private static final String TAG_CONTACTS = "contacts";
   private static final String TAG_ID = "id";
   private static final String TAG_NAME = "name";
   private static final String TAG_EMAIL = "email";
   private static final String TAG_ADDRESS = "address";
   private static final String TAG_GENDER = "gender";
   private static final String TAG_PHONE = "phone";
   private static final String TAG_PHONE_MOBILE = "mobile";
   private static final String TAG_PHONE_HOME = "home";
   private static final String TAG_PHONE_OFFICE = "office";
   
   // contacts JSONArray
   JSONArray contacts = null;
   

   2.2. Use parser class to get JSONObject and looping through each json item. Below i am creating an instance of JSONParser class and using for loop i am looping through each json item and finally storing each json data in variable.

   // Creating JSON Parser instance
   JSONParser jParser = new JSONParser();
   
   // getting JSON string from URL
   JSONObject json = jParser.getJSONFromUrl(url);
   
       try {
       // Getting Array of Contacts
       contacts = json.getJSONArray(TAG_CONTACTS);
   
       // looping through All Contacts
       for(int i = 0; i < contacts.length(); i++){
           JSONObject c = contacts.getJSONObject(i);
   
           // Storing each json item in variable
           String id = c.getString(TAG_ID);
           String name = c.getString(TAG_NAME);
           String email = c.getString(TAG_EMAIL);
           String address = c.getString(TAG_ADDRESS);
           String gender = c.getString(TAG_GENDER);
   
           // Phone number is agin JSON Object
           JSONObject phone = c.getJSONObject(TAG_PHONE);
           String mobile = phone.getString(TAG_PHONE_MOBILE);
           String home = phone.getString(TAG_PHONE_HOME);
           String office = phone.getString(TAG_PHONE_OFFICE);
   
       }
   } catch (JSONException e) {
       e.printStackTrace();
   }
   

Here is a function I came up with

function getElementsById(elementID){
    var elementCollection = new Array();
    var allElements = document.getElementsByTagName("*");
    for(i = 0; i < allElements.length; i++){
        if(allElements[i].id == elementID)
            elementCollection.push(allElements[i]);

    }
    return elementCollection;
}

Apparently there is a convention supported by prototype, and probably other major JavaScript libraries.

However, I have come to discover that dollar sign function has become the more-or-less de facto shortcut to document.getElementById(). Let’s face it, we all use document.getElementById() a lot. Not only does it take time to type, but it adds bytes to your code as well.

here is the function from prototype:

function $(element) {
  if (arguments.length > 1) {
    for (var i = 0, elements = [], length = arguments.length; i < length; i++)
      elements.push($(arguments[i]));
    return elements;
  }
  if (Object.isString(element))
    element = document.getElementById(element);
  return Element.extend(element);
}

I repaired it using the Microsoft .NET Framework Repair Tool. After reloading my project a couple of times after that the problem went away.

I just look for _sdk, _sdk_ or sdk_, or even just sdk part in Build.PRODUCT:

if(Build.PRODUCT.matches(".*_?sdk_?.*")){
  //-- emulator --
}else{
  //-- other device --
}

if you are using mysql use 127.0.0.1 instead of localhost in mysql_connect function it helped me

if anyone want to add a value inside loop then you can use this its working 100%

{% set ftotal= {'total': 0} %} 
{%- for pe in payment_entry -%}
    {% if ftotal.update({'total': ftotal.total + 5}) %}{% endif %} 
{%- endfor -%}

{{ftotal.total}}

output = 5

Just read this great .Net DI container comparison blog by Philip Mat.

He does some thorough performance comparison tests on;

• Autofac
• StructureMap
• Ninject
• Unity
• Castle.Windsor
• Spring.Net

He recommends Autofac as it is small, fast, and easy to use ... I agree. It appears that Unity and Ninject are the slowest in his tests.

It seems that your project is written in Python < 3. This is because the file() builtin function is removed in Python 3. Try using Python 2to3 tool or edit the erroneous file yourself.

EDIT: BTW, the project page clearly mentions that

Gunicorn requires Python 2.x >= 2.5. Python 3.x support is planned.

I can't believe all of the people that say using it always is a "best practice" and such.

Use "this" when there is ambiguity, as in Corey's example or when you need to pass the object as a parameter, as in Ryan's example. There is no reason to use it otherwise because being able to resolve a variable based on the scope chain should be clear enough that qualifying variables with it should be unnecessary.

EDIT: The C# documentation on "this" indicates one more use, besides the two I mentioned, for the "this" keyword - for declaring indexers

EDIT: @Juan: Huh, I don't see any inconsistency in my statements - there are 3 instances when I would use the "this" keyword (as documented in the C# documentation), and those are times when you actually need it. Sticking "this" in front of variables in a constructor when there is no shadowing going on is simply a waste of keystrokes and a waste of my time when reading it, it provides no benefit.

Use of:

echo elapsed_time('2016-05-09 17:00:00'); // 18 saat 8 dakika önce yazildi.

Function:

function elapsed_time($time){// Nekadar zaman geçmis

        $diff = time() - strtotime($time); 

        $sec = $diff;
        $min = floor($diff/60);
        $hour = floor($diff/(60*60));
        $hour_min = floor($min - ($hour*60));
        $day = floor($diff/(60*60*24));
        $day_hour = floor($hour - ($day*24));
        $week = floor($diff/(60*60*24*7));
        $mon = floor($diff/(60*60*24*7*4));
        $year = floor($diff/(60*60*24*7*4*12));

        //difference calculate to string
        if($sec < (60*5)){
            return 'simdi yazildi.';
        }elseif($min < 60){
            return 'biraz önce yazildi.';
        }elseif($hour < 24){
            return $hour.' saat '.$hour_min.' dakika önce yazildi.';
        }elseif($day < 7){
            if($day_hour!=0){$day_hour=$day_hour.' saat ';}else{$day_hour='';}
            return $day.' gün '.$day_hour.'önce yazildi.';
        }elseif($week < 4){
            return $week.' hafta önce yazildi.';
        }elseif($mon < 12){
            return $mon.' ay önce yazildi.';
        }else{

Edit 2014/10: by popular demand I'm maintaining and moving this to GitHub. Please check cprcrack/VideoEnabledWebView for the last version. Will keep this answer only for reference.

Edit 2014/01: improved example usage to include the nonVideoLayout, videoLayout, and videoLoading views, for those users requesting more example code for better understading.

Edit 2013/12: some bug fixes related to Sony Xperia devices compatibility, but which in fact affected all devices.

Edit 2013/11: after the release of Android 4.4 KitKat (API level 19) with its new Chromium webview, I had to work hard again. Several improvements were made. You should update to this new version. I release this source under WTFPL.

Edit 2013/04: after 1 week of hard work, I finally have achieved everything I needed. I think this two generic classes that I have created can solve all you problems.

VideoEnabledWebChromeClient can be used alone if you do not require the functionality that VideoEnabledWebView adds. But VideoEnabledWebView must always rely on a VideoEnabledWebChromeClient. Please read all the comments of the both classes carefully.

/**
 * This class serves as a WebChromeClient to be set to a WebView, allowing it to play video.
 * Video will play differently depending on target API level (in-line, fullscreen, or both).
 *
 * It has been tested with the following video classes:
 * - android.widget.VideoView (typically API level <11)
 * - android.webkit.HTML5VideoFullScreen$VideoSurfaceView/VideoTextureView (typically API level 11-18)
 * - com.android.org.chromium.content.browser.ContentVideoView$VideoSurfaceView (typically API level 19+)
 * 
 * Important notes:
 * - For API level 11+, android:hardwareAccelerated="true" must be set in the application manifest.
 * - The invoking activity must call VideoEnabledWebChromeClient's onBackPressed() inside of its own onBackPressed().
 * - Tested in Android API levels 8-19. Only tested on http://m.youtube.com.

    super.onCreate(savedInstanceState);

    // Set layout
    setContentView(R.layout.activity_main);

    // Initialize the VideoEnabledWebChromeClient and set event handlers

        {
            // Your code...
        }
    };
    webChromeClient.setOnToggledFullscreen(new VideoEnabledWebChromeClient.ToggledFullscreenCallback()
    {
        @Override
        public void toggledFullscreen(boolean fullscreen)
        {
            // Your code to handle the full-screen change, for example showing and hiding the title bar. Example:
            if (fullscreen)
            {
                WindowManager.LayoutParams attrs = getWindow().getAttributes();
                attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
                attrs.flags |= WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON;
                getWindow().setAttributes(attrs);
                if (android.os.Build.VERSION.SDK_INT >= 14)
                {
                    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LOW_PROFILE);
                }
            }
            else
            {

        }
    });
    webView.setWebChromeClient(webChromeClient);

    // Navigate everywhere you want, this classes have only been tested on YouTube's mobile site
    webView.loadUrl("http://m.youtube.com");
}

And don't forget to call onBackPressed():

@Override
public void onBackPressed()
{
    // Notify the VideoEnabledWebChromeClient, and handle it ourselves if it doesn't handle it
    if (!webChromeClient.onBackPressed())
    {
        if (webView.canGoBack())
        {
            webView.goBack();
        }
        else
        {
            // Close app (presumably)
            super.onBackPressed();
        }
    }
}

If you already know size of the char*, use this instead

char* data = ...;
int size = ...;
std::string myString(data, size);

This doesn't use strlen.

EDIT: If string variable already exists, use assign():

std::string myString;
char* data = ...;
int size = ...;
myString.assign(data, size);

Add this:

<div class="footer fixed-bottom">

Just a note that as of Ruby 2.0 there is no need to add # encoding: utf-8. UTF-8 is automatically detected.

Copied from MSDN:

At compile time, verbatim strings are converted to ordinary strings with all the same escape sequences. Therefore, if you view a verbatim string in the debugger watch window, you will see the escape characters that were added by the compiler, not the verbatim version from your source code. For example, the verbatim string @"C:\files.txt" will appear in the watch window as "C:\\files.txt".

After a few "try and test" iterations I've found a way (still not present here) to get size of file in cycle variable (not a command line parameter):

for %%i in (*.txt) do (
    echo %%~z%i
)

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

String[] errorSoon = new String[n];

With n being how many strings it needs to hold.

You can do that in the declaration, or do it without the String[] later on, so long as it's before you try use them.

This seems to be working for a little rigidly geometrically set app where it needs to run on both mobile and other browsers with little change, so finding the mobile/non-mobile browser status and for mobiles setting the viewport to device-width is needed. As scripts can be run from the header, the below js in header seems to change the metatag for device-width Before the page loads. One might note that the use of navigator.userAgent is stipulated as experimental. The script must follow the metatag entry to be changed, so one must choose some initial content, and then change on some condition.

<meta name="viewport" content="width=device-width, initial-scale=1.0">
<script>  
  var userAgentHeader = navigator.userAgent ; 
  var browserIsMobileOrNot = "mobileNOT" ; 
  if( userAgentHeader.includes( "Mobi" ) ) { 
    browserIsMobileOrNot = "mobileYES" ; 
    //document.querySelector('meta[name="viewport"]').setAttribute( "content", "width=device-width, initial-scale=1.0" );
  } else { 
    browserIsMobileOrNot = "mobileNOT" ;  
    document.querySelector('meta[name="viewport"]').setAttribute( "content", "");
  }
</script>

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

The xargs utility reads space, tab, newline and end-of-file delimited strings from the standard input and executes utility with the strings as arguments.

You want to avoid using space as a delimiter. This can be done by changing the delimiter for xargs. According to the manual:

 -0      Change xargs to expect NUL (``\0'') characters as separators,
         instead of spaces and newlines.  This is expected to be used in
         concert with the -print0 function in find(1).

Such as:

 find . -name "*.mp3" -print0 | xargs -0 mplayer

To answer the question about playing the seventh mp3; it is simpler to run

 mplayer "$(ls *.mp3 | sed -n 7p)"

Use an associative array, with command names as keys.

# Requires bash 4, though
declare -A magic_variable=()

function grep_search() {
    magic_variable[$1]=$( ls | tail -1 )
    echo ${magic_variable[$1]}
}

If you can't use associative arrays (e.g., you must support bash 3), you can use declare to create dynamic variable names:

declare "magic_variable_$1=$(ls | tail -1)"

and use indirect parameter expansion to access the value.

var="magic_variable_$1"
echo "${!var}"

See BashFAQ: Indirection - Evaluating indirect/reference variables.

          if(!empty($value) || $value != NULL || $value != ""){
              return true;
              break;//stop the process we have seen that at least 1 of the array has value so its not empty
          }
      }
      return false;

In main(), there is also:

<?php } ?>

<!-- Remove cron job -->
<?php if(!empty($_POST['remove_cron'])) { ?>

I was having this problem but i found out that it was a permissions problem I changed my permissions to 0744 and now it works. I don't know if this was your problem but it worked for me.

If running Windows 10:

1. Open the start menu
2. Type path
3. Click Edit the system environment variables (usually, it's the top search result) and continue on step 6 below.

If on older Windows:

1. Show Desktop.

2. Right Click My Computer shortcut in the desktop.

3. Click Properties.

4. You should see a section of control Panel - Control Panel\System and Security\System.

5. Click Advanced System Settings on the Left menu.

6. Click Enviornment Variables towards the bottom of the System Properties window.

7. Select PATH in the user variables list.

8. Append your PHP Path (C:\myfolder\php) to your PATH variable, separated from the already existing string by a semi colon.

9. Click OK

10. Open your "cmd"

11. Type PATH, press enter

12. Make sure that you see your PHP folder among the list.

That should work.

Note: Make sure that your PHP folder has the php.exe. It should have the file type CLI. If you do not have the php.exe, go ahead and check the installation guidelines at - http://www.php.net/manual/en/install.windows.manual.php - and download the installation file from there.

The same example for Node.js:

var webdriver = require('selenium-webdriver');
...
driver = new webdriver.Builder().
                    withCapabilities(capabilities).
                    build();
...
driver.findElement(webdriver.By.tagName("body")).sendKeys(webdriver.Key.COMMAND + "t");

The first argument to printf() is always a string value, known as a format control string. This string may be regular text, such as

printf("Hello, World\n"); // \n indicates a newline character

or

char greeting[] = "Hello, World\n";
printf(greeting);

This string may also contain one or more conversion specifiers; these conversion specifiers indicate that additional arguments have been passed to printf(), and they specify how to format those arguments for output. For example, I can change the above to

char greeting[] = "Hello, World";
printf("%s\n", greeting);

The "%s" conversion specifier expects a pointer to a 0-terminated string, and formats it as text.

For signed decimal integer output, use either the "%d" or "%i" conversion specifiers, such as

printf("%d\n", addNumber(a,b));

You can mix regular text with conversion specifiers, like so:

printf("The result of addNumber(%d, %d) is %d\n", a, b, addNumber(a,b));

Note that the conversion specifiers in the control string indicate the number and types of additional parameters. If the number or types of additional arguments passed to printf() don't match the conversion specifiers in the format string then the behavior is undefined. For example:

printf("The result of addNumber(%d, %d) is %d\n", addNumber(a,b));

will result in anything from garbled output to an outright crash.

There are a number of additional flags for conversion specifiers that control field width, precision, padding, justification, and types. Check your handy C reference manual for a complete listing.

Although recently its use is undefined, a common and useful use for the form feed is to separate sections of code vertically, like so: (from http://ergoemacs.org/emacs/emacs_form_feed_section_paging.html)

here is a ghetto way, but it works :)

DateTime dt = DateTime.Now; //get a DateTime variable for the example
string newSecondsValue = "00";
dt = Convert.ToDateTime(dt.ToString("MM/dd/yyyy hh:mm:" + newSecondsValue));

It means:

'O'     (Python) objects

Source.

The first character specifies the kind of data and the remaining characters specify the number of bytes per item, except for Unicode, where it is interpreted as the number of characters. The item size must correspond to an existing type, or an error will be raised. The supported kinds are to an existing type, or an error will be raised. The supported kinds are:

'b'       boolean
'i'       (signed) integer
'u'       unsigned integer
'f'       floating-point
'c'       complex-floating point
'O'       (Python) objects
'S', 'a'  (byte-)string
'U'       Unicode
'V'       raw data (void)

Another answer helps if need check types.

This may already be an answer but you could use random.shuffle. Example:

import random
foo = ['a', 'b', 'c', 'd', 'e']
random.shuffle(foo)

ES6 solution with Koa.

  async recent() {
    data = await ReadSchema.find({}, { sort: 'created_at' });
    ctx.body = data;
  }

Are you sure that the XML file is in the correct character encoding? FileReader always uses the platform default encoding, so if the "working" server had a default encoding of (say) ISO-8859-1 and the "problem" server uses UTF-8 you would see this error if the XML contains any non-ASCII characters.

Does it work if you create the InputSource from a FileInputStream instead of a FileReader?

If its in a landscape then you will be needing more width and less height! That's just what all websites have.

Lets go with a basic first then the rest!

The basic CSS:

By CSS you can do this,

#body {
width: 100%;
height: 100%;
}

Here you are using a div with id body, as:

<body>
  <div id="body>
    all the text would go here!
  </div>
</body>

Then you can have a web page with 100% height and width.

What if he tries to resize the window?

The issues pops up, what if he tries to resize the window? Then all the elements inside #body would try to mess up the UI. For that you can write this:

#body {
height: 100%;
width: 100%;
}

And just add min-height max-height min-width and max-width.

This way, the page element would stay at the place they were at the page load.

Using JavaScript:

Using JavaScript, you can control the UI, use jQuery as:

$('#body').css('min-height', '100%');

And all other remaining CSS properties, and JS will take care of the User Interface when the user is trying to resize the window.

How to not add scroll to the web page:

If you are not trying to add a scroll, then you can use this JS

$('#body').css('min-height', screen.height); // or anyother like window.height

This way, the document will get a new height whenever the user would load the page.

Second option is better, because when users would have different screen resolutions they would want a CSS or Style sheet created for their own screen. Not for others!

Tip: So try using JS to find current Screen size and edit the page! :)

I encountered this running a brand new project. Neither the Allow or Always Allow button seemed to work, however it wasn't giving me the 'incorrect password' shaking feedback. What was happening was that there were multiple dialog boxes all in the same position, so as I entered a password and clicked Allow nothing changed visually. I ended up having at least 3 dialogs all stacked up on each other, which I only discovered when I tried dragging the dialog. Entering passwords into each of them let my project finish building.

Method proposed @Lelio Faieta is working for me, but because i use bootstrap theme, it remove all bootstrap settings for select2. So I used following code:

$("#remote option").remove();

To Encrypt:

$ openssl bf < arquivo.txt > arquivo.txt.bf

To Decrypt:

$ openssl bf -d < arquivo.txt.bf > arquivo.txt

bf === Blowfish in CBC mode

With all the solutions above even though you're hiding the code, you'll still get the [<matplotlib.lines.Line2D at 0x128514278>] crap above your figure which you probably don't want.

If you actually want to get rid of the input rather than just hiding it, I think the cleanest solution is to save your figures to disk in hidden cells, and then just including the images in Markdown cells using e.g. ![Caption](figure1.png).

As mentioned in the other solutions, we want to be able to hit the file system once while mimicking the behaviour of mkdir -p. I don't think that this is possible to do, but we should get as close as possible.

Code first, explanation later:

import os
import errno

def mkdir_p(path):
    """ 'mkdir -p' in Python """
    try:
        os.makedirs(path)
    except OSError as exc:  # Python >2.5
        if exc.errno == errno.EEXIST and os.path.isdir(path):
            pass
        else:
            raise

As the comments to @tzot's answer indicate there are problems with checking whether you can create a directory before you actually create it: you can't tell whether someone has changed the file system in the meantime. That also fits in with Python's style of asking for forgiveness, not permission.

So the first thing we should do is try to make the directory, then if it goes wrong, work out why.

As Jacob Gabrielson points out, one of the cases we must look for is the case where a file already exists where we are trying to put the directory.

With mkdir -p:

$ touch /tmp/foo
$ mkdir -p /tmp/foo
mkdir: cannot create directory '/tmp/foo': File exists

The analogous behaviour in Python would be to raise an exception.

So we have to work out if this was the case. Unfortunately, we can't. We get the same error message back from makedirs whether a directory exists (good) or a file exists preventing the creation of the directory (bad).

The only way to work out what happened is to inspect the file system again to see if there is a directory there. If there is, then return silently, otherwise raise the exception.

The only problem is that the file system may be in a different state now than when makedirs was called. eg: a file existed causing makedirs to fail, but now a directory is in its place. That doesn't really matter that much, because the the function will only exit silently without raising an exception when at the time of the last file system call the directory existed.

put at the start of my programs its use full for work with python

import sys

if sys.version_info[0] < 3:
    raise Exception("Python 3 or a more recent version is required.")

This code will help full for the progress

If you want to color your terminal console, then you can use npm package chalk

npm i chalk

You need to use a constant.

CONST NumberOfZombies = 20000
Dim Zombies(NumberOfZombies) As Zombies

or if you want to use a variable you have to do it this way:

Dim NumberOfZombies As Integer
NumberOfZombies = 20000

Dim Zombies() As Zombies

ReDim Zombies(NumberOfZombies)

This is untested, but I believe the syntax should work for a lambda query. As you join more tables with this syntax you have to drill further down into the new objects to reach the values you want to manipulate.

var fullEntries = dbContext.tbl_EntryPoint
    .Join(
        dbContext.tbl_Entry,
        entryPoint => entryPoint.EID,
        entry => entry.EID,
        (entryPoint, entry) => new { entryPoint, entry }
    )
    .Join(
        dbContext.tbl_Title,
        combinedEntry => combinedEntry.entry.TID,
        title => title.TID,
        (combinedEntry, title) => new 
        {
            UID = combinedEntry.entry.OwnerUID,
            TID = combinedEntry.entry.TID,
            EID = combinedEntry.entryPoint.EID,
            Title = title.Title
        }
    )
    .Where(fullEntry => fullEntry.UID == user.UID)
    .Take(10);

Based on this code (which you provided in response to Alex's answer):

Editable newTxt=(Editable)userName1.getText(); 
String newString = newTxt.toString();

It looks like you're trying to get the text out of a TextView or EditText. If that's the case then this should work:

String newString = userName1.getText().toString(); 

Try this

$(element).css({
    "propertyName1":"propertyValue1",
    "propertyName2":"propertyValue2"
})

When MS-DOS and Windows 3.1 operated in 16-bit mode, an Intel 8086 word was 16 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 16 bits.

When Windows NT operated in 32-bit mode, an Intel 80386 word was 32 bits, a Microsoft WORD was 16 bits, a Microsoft DWORD was 32 bits, and a typical compiler's unsigned int was 32 bits. The names WORD and DWORD were no longer self-descriptive but they preserved the functionality of Microsoft programs.

When Windows operates in 64-bit mode, an Intel word is 64 bits, a Microsoft WORD is 16 bits, a Microsoft DWORD is 32 bits, and a typical compiler's unsigned int is 32 bits. The names WORD and DWORD are no longer self-descriptive, AND an unsigned int no longer conforms to the principle of least surprises, but they preserve the functionality of lots of programs.

I don't think WORD or DWORD will ever change.

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

This explains the whole thing:

The HTTP Content-Security-Policy (CSP) upgrade-insecure-requests directive instructs user agents to treat all of a site's insecure URLs (those served over HTTP) as though they have been replaced with secure URLs (those served over HTTPS). This directive is intended for web sites with large numbers of insecure legacy URLs that need to be rewritten.

The upgrade-insecure-requests directive is evaluated before block-all-mixed-content and if it is set, the latter is effectively a no-op. It is recommended to set one directive or the other, but not both.

The upgrade-insecure-requests directive will not ensure that users visiting your site via links on third-party sites will be upgraded to HTTPS for the top-level navigation and thus does not replace the Strict-Transport-Security (HSTS) header, which should still be set with an appropriate max-age to ensure that users are not subject to SSL stripping attacks.

1. Create a state property for the default option text in the constructor
   • Don't worry about the default option value
2. Add an option tag to the render function. Only show using state and ternary expression
3. Create a function to handle when an option was selected

4. Change the state of the default option value in this event handler function to null

   Class MySelect extends React.Component
   {
       constructor()
       {
           super()
           this.handleChange = this.handleChange.bind(this);
           this.state = {
               selectDefault: "Select An Option"
           }
       }
       handleChange(event)
       {
           const selectedValue = event.target.value;
           //do something with selectedValue
           this.setState({
               selectDefault: null
           });
       }
       render()
       {
           return (
           <select name="selectInput" id="selectInput" onChange={this.handleChange} value= 
               {this.selectedValue}>
            {this.state.selectDefault ? <option>{this.state.selectDefault}</option> : ''}
               {'map list or static list of options here'}
           </select>
           )
       }
   }

There is a shorter alternative to the previous answer. SVG Elements can also be grouped by nesting svg elements:

<svg xmlns="http://www.w3.org/2000/svg"
  xmlns:xlink="http://www.w3.org/1999/xlink">
  <svg x="10">
    <rect x="10" y="10" height="100" width="100" style="stroke:#ff0000;fill: #0000ff"/>
  </svg>
  <svg x="200">
    <rect x="10" y="10" height="100" width="100" style="stroke:#009900;fill: #00cc00"/>
  </svg>
</svg>

The two rectangles are identical (apart from the colors), but the parent svg elements have different x values.

See http://tutorials.jenkov.com/svg/svg-element.html.

$dateTime = new DateTime('now', new DateTimeZone('Asia/Kolkata')); 
echo $dateTime->modify("+10 minutes")->format("H:i:s A");

[My answer is wrong, but I've left it here because the comments are useful].

Forward declaring enums is non-standard, because pointers to different enum types are not guaranteed to be the same size. The compiler may need to see the definition to know what size pointers can be used with this type.

In practice, at least on all the popular compilers, pointers to enums are a consistent size. Forward declaration of enums is provided as a language extension by Visual C++, for example.

This shows you how to

1. Read in an XML file to a DOM
2. Filter out a set of Nodes with XPath
3. Perform a certain action on each of the extracted Nodes.

We will call the code with the following statement

processFilteredXml(xmlIn, xpathExpr,(node) -> {/*Do something...*/;});

In our case we want to print some creatorNames from a book.xml using "//book/creators/creator/creatorName" as xpath to perform a printNode action on each Node that matches the XPath.

Full code

@Test
public void printXml() {
    try (InputStream in = readFile("book.xml")) {
        processFilteredXml(in, "//book/creators/creator/creatorName", (node) -> {
            printNode(node, System.out);
        });
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

private InputStream readFile(String yourSampleFile) {
    return Thread.currentThread().getContextClassLoader().getResourceAsStream(yourSampleFile);
}

private void processFilteredXml(InputStream in, String xpath, Consumer<Node> process) {
    Document doc = readXml(in);
    NodeList list = filterNodesByXPath(doc, xpath);
    for (int i = 0; i < list.getLength(); i++) {
        Node node = list.item(i);
        process.accept(node);
    }
}

public Document readXml(InputStream xmlin) {
    try {
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        return db.parse(xmlin);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

private NodeList filterNodesByXPath(Document doc, String xpathExpr) {
    try {
        XPathFactory xPathFactory = XPathFactory.newInstance();
        XPath xpath = xPathFactory.newXPath();
        XPathExpression expr = xpath.compile(xpathExpr);
        Object eval = expr.evaluate(doc, XPathConstants.NODESET);
        return (NodeList) eval;
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

private void printNode(Node node, PrintStream out) {
    try {
        Transformer transformer = TransformerFactory.newInstance().newTransformer();
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
        transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
        StreamResult result = new StreamResult(new StringWriter());
        DOMSource source = new DOMSource(node);
        transformer.transform(source, result);
        String xmlString = result.getWriter().toString();
        out.println(xmlString);
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Prints

<creatorName>Fosmire, Michael</creatorName>

<creatorName>Wertz, Ruth</creatorName>

<creatorName>Purzer, Senay</creatorName>

For book.xml

<book>

If you don't know the size, you can use:

std::sort(v, v + sizeof v / sizeof v[0]);

Even if you do know the size, it's a good idea to code it this way as it will reduce the possibility of a bug if the array size is changed later.

There is a way to redirect JVM thread dump output on break signal to separate file with LogVMOutput diagnostic option:

-XX:+UnlockDiagnosticVMOptions -XX:+LogVMOutput -XX:LogFile=jvm.log

Another problem solved by the rubber duck:

The css is right but you still have to remember that the HTML elements order matters: the div has to come before the header. http://jsfiddle.net/Fq2Na/1/

Change your HTML code to have the div before the header:

<section>
<div><button>button</button></div>
<h1>some long long long long header, a whole line, 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6</h1>
</section>

And keep your CSS to the simple div { float: right; }.

A Python list:

>>> a = ['a', 'b', 'c', 'd', 'b']

To get unique items, just transform it into a set (which you can transform back again into a list if required):

>>> b = set(a)
>>> print(b)
{'b', 'c', 'd', 'a'}

I don't see anything in here to suggest that this is a web-app but I have experienced this issue myself - I've got two xcopy commands on a post-build event and only one of them was failing. Something had a lock on the file, and it wasn't Visual Studio (as I tried restarting it.)

The only other thing that would have used the dll I built was IIS. And lo and behold,

A simple iisreset did the trick for me.

Just use break, like that:

int cont = 0;
foreach (ListViewItem lvi in listView.Items) {
   if(cont==50) { //if listViewItem reach 50 break out.
      break; 
   }
   cont++;   //increment cont.
}

Don't forget that in .htaccess files it is a relative URL that is matched.

In a .htaccess file the following RewriteRule will never match:

RewriteRule ^/(.*)     /something/$s

    for ($i = 0; $i<10; $i++){

        echo "<br> Line to show.";
        echo str_pad('',4096)."\n";    

        ob_flush();
        flush();
        sleep(2);
    }

    echo "Done.";

    ob_end_flush();
?>

and its very important to keep de "4096" part because it seems that "fills" the buffer...

Hmm, from the examples you gave it seems like "$_SERVER['REQUEST_URI']" and the explode() function could help you. You could use explode to break up the URL following the domain name into an array, separating it at each forward-slash.

As a very basic example, something like this could be implemented:

$crumbs = explode("/",$_SERVER["REQUEST_URI"]);
foreach($crumbs as $crumb){
    echo ucfirst(str_replace(array(".php","_"),array(""," "),$crumb) . ' ');
}

my solution:

background-image: url(IMAGE_URL); /* fallback */

background-image: linear-gradient(to bottom, rgba(0,0,0,0.7) 0%,rgba(0,0,0,0.7) 100%), url(IMAGE_URL);

h/H = 12/24 hours means you will write hh:mm = 12 hours format and HH:mm = 24 hours format

You can use below code

$.when( Typer() ).done(function() {
       playBGM();
});

Possibilities:

• Use String.equals():

  if (some_string.equals("john") ||
      some_string.equals("mary") ||
      some_string.equals("peter"))
  {
  }
  

• Use a regular expression:

  if (some_string.matches("john|mary|peter"))
  {
  }
  

• Store a list of strings to be matched against in a Collection and search the collection:

  Set<String> names = new HashSet<String>();
  names.add("john");
  names.add("mary");
  names.add("peter");
  
  if (names.contains(some_string))
  {
  }
  

FOR BOOTSTRAP 3.X:

Bootstrap now has the following style for table cells:

.table tbody > tr > td{
    vertical-align: top;
}

The way to go is to add your own class, adding more specificity to the previous selector:

.table tbody > tr > td.vert-aligned {
    vertical-align: middle;
}

And then add the class to your tds:

<tr>
    <td class="vert-aligned"></td>
    ...
</tr>

FOR BOOTSTRAP 2.X

There is no way to do this with Bootstrap.

When used in table cells, vertical-align does what most people expect it to, which is to mimic the (old, deprecated) valign attribute. In a modern, standards-compliant browser, the following three code snippets do the same thing:

<td valign="middle"> <!-- but you shouldn't ever use valign --> </td>
<td style="vertical-align:middle"> ... </td>
<div style="display:table-cell; vertical-align:middle"> ... </div>

Check your fiddle updated

Further

• vertical-align: middle with Bootstrap 2
• Understanding vertical-align
• Vertical alignment of elements in a div

Also, you can't refer to the td class using .vert because Bootstrap already has this class:

.table td {
   padding: 8px;
   line-height: 20px;
   text-align: left;
   vertical-align: top; // The problem!
   border-top: 1px solid #dddddd;
}

And is overloading the vertical-align: middle in '.vert' class, so you have to define this class as td.vert.

If you want to delete all the .pyc files from the project folder.

First, you have

cd <path/to/the/folder>

then find all the .pyc file and delete.

find . -name \*.pyc -delete

Running a command through /usr/bin/env has the benefit of looking for whatever the default version of the program is in your current environment.

This way, you don't have to look for it in a specific place on the system, as those paths may be in different locations on different systems. As long as it's in your path, it will find it.

One downside is that you will be unable to pass more than one argument (e.g. you will be unable to write /usr/bin/env awk -f) if you wish to support Linux, as POSIX is vague on how the line is to be interpreted, and Linux interprets everything after the first space to denote a single argument. You can use /usr/bin/env -S on some versions of env to get around this, but then the script will become even less portable and break on fairly recent systems (e.g. even Ubuntu 16.04 if not later).

Another downside is that since you aren't calling an explicit executable, it's got the potential for mistakes, and on multiuser systems security problems (if someone managed to get their executable called bash in your path, for example).

#!/usr/bin/env bash #lends you some flexibility on different systems
#!/usr/bin/bash     #gives you explicit control on a given system of what executable is called

In some situations, the first may be preferred (like running python scripts with multiple versions of python, without having to rework the executable line). But in situations where security is the focus, the latter would be preferred, as it limits code injection possibilities.

By using jot:

jot -w "http://example.com/%d.jpg" 1000 1

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy");
Date d = dateFormat.parse(datestring)

In a for..of loop we can achieve this via array.entries(). array.entries returns a new Array iterator object. An iterator object knows how to access items from an iterable one at the time, while keeping track of its current position within that sequence.

When the next() method is called on the iterator key value pairs are generated. In these key value pairs the array index is the key and the array item is the value.

let arr = ['a', 'b', 'c'];_x000D_
let iterator = arr.entries();_x000D_
console.log(iterator.next().value); // [0, 'a']_x000D_
console.log(iterator.next().value); // [1, 'b']

A for..of loop is basically a construct which consumes an iterable and loops through all elements (using an iterator under the hood). We can combine this with array.entries() in the following manner:

array = ['a', 'b', 'c'];_x000D_
_x000D_
for (let indexValue of array.entries()) {_x000D_
  console.log(indexValue);_x000D_
}_x000D_
_x000D_
_x000D_
// we can use array destructuring to conveniently_x000D_
// store the index and value in variables_x000D_
for (let [index, value] of array.entries()) {_x000D_
   console.log(index, value);_x000D_
}

If those are actually fields of a certain class, then you can get them with a little help of reflection:

package test;

import java.lang.reflect.Field;
import java.lang.reflect.ParameterizedType;
import java.util.ArrayList;
import java.util.List;

public class Test {

    List<String> stringList = new ArrayList<String>();
    List<Integer> integerList = new ArrayList<Integer>();

    public static void main(String... args) throws Exception {
        Field stringListField = Test.class.getDeclaredField("stringList");
        ParameterizedType stringListType = (ParameterizedType) stringListField.getGenericType();
        Class<?> stringListClass = (Class<?>) stringListType.getActualTypeArguments()[0];
        System.out.println(stringListClass); // class java.lang.String.

        Field integerListField = Test.class.getDeclaredField("integerList");
        ParameterizedType integerListType = (ParameterizedType) integerListField.getGenericType();
        Class<?> integerListClass = (Class<?>) integerListType.getActualTypeArguments()[0];
        System.out.println(integerListClass); // class java.lang.Integer.
    }
}

You can also do that for parameter types and return type of methods.

But if they're inside the same scope of the class/method where you need to know about them, then there's no point of knowing them, because you already have declared them yourself.

Your NewClass inherits from UIViewController. You declared signedIn in ViewController. If you want NewClass to be able to identify that variable it will have to be declared in a class that your NewClass inherits from.

C# has a few more features than Java. Take delegates for example: Many very simple C# applications use delegates, while the Java folks figures that the observer pattern was sufficient. So, in order for a tool to convert a C# application which uses delegates it would have to translate the structure from using delegates to an implementation of the observer pattern. Another problem is the fact that C# methods are not virtual by default while Java methods are. Additionally, Java doesn't have a way to make methods non virtual. This creates another problem: an application in C# could leverage non virtual method behavior through polymorphism in a way the does not translate directly to Java. If you look around you will probably find that there are lots of tools to convert Java to C# since it is a simpler language (please don't flame me I didn't say worse I said simpler); however, you will find very few if any decent tools that convert C# to Java.

I would recommend changing your approach to converting from Java to C# as it will create fewer headaches in the long run. Db4Objects recently released their internal tool which they use to convert Db4o into C# to the public. It is called Sharpen. If you register with their site you can view this link with instructions on how to use Sharpen: http://developer.db4o.com/Resources/view.aspx/Reference/Sharpen/How_To_Setup_Sharpen

(I've been registered with them for a while and they're good about not spamming)

LinearLayout YOUR_LinearLayout =(LinearLayout)findViewById(R.id.YOUR_LinearLayout)
    LinearLayout.LayoutParams param = new LinearLayout.LayoutParams(
                       /*width*/ ViewGroup.LayoutParams.MATCH_PARENT,
               /*height*/ 100,
               /*weight*/ 1.0f
                );
                YOUR_LinearLayout.setLayoutParams(param);

Add up to Dmitry's answer, if you don't want to handle unique key IDs manually, you can use React.Children.toArray as proposed in the React documentation

React.Children.toArray

Returns the children opaque data structure as a flat array with keys assigned to each child. Useful if you want to manipulate collections of children in your render methods, especially if you want to reorder or slice this.props.children before passing it down.

Note:

React.Children.toArray() changes keys to preserve the semantics of nested arrays when flattening lists of children. That is, toArray prefixes each key in the returned array so that each element’s key is scoped to the input array containing it.

 <div>
    <ul>
      {
        React.Children.toArray(
          this.state.data.map((item, i) => <li>Test</li>)
        )
      }
    </ul>
  </div>

The above suggestions did not work for me. What really worked was the inclusion of the following lines in the application.properties

spring.datasource.testWhileIdle = true
spring.datasource.timeBetweenEvictionRunsMillis = 3600000
spring.datasource.validationQuery = SELECT 1

You can find the explanation out here

A convenient way (JBoss recommended) to include Java EE 6 dependencies is demonstrated below. As a result dependencies are placed separately (not all in one jar as in javaee-web-api), source files and javadocs of the libraries are available to download from maven repository.

<properties>
    <jboss.javaee6.spec.version>2.0.0.Final</jboss.javaee6.spec.version>
</properties>
<dependencies>
    <dependency>
        <groupId>org.jboss.spec</groupId>
        <artifactId>jboss-javaee-web-6.0</artifactId>
        <version>${jboss.javaee6.spec.version}</version>
        <scope>provided</scope>
        <type>pom</type>
    </dependency>
</dependencies>

To include individual dependencies only, dependencyManagement section and scope import can be used:

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.jboss.spec</groupId>
                <artifactId>jboss-javaee6-specs-bom</artifactId>
                <version>${jboss.javaee6.spec.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <!-- No need specifying version and scope. It is defaulted to version and scope from Bill of Materials (bom) imported pom. -->
        <dependency>
            <groupId>org.jboss.spec.javax.servlet</groupId>
            <artifactId>jboss-servlet-api_3.0_spec</artifactId>

None of the above answers worked for me, but here's what did.

1) delete .git/ from your project
2) clone the remote repo to some new location like your desktop. git clone https://github.com/foo/bar.git
3) move .git/ from the new location into the old location
4) re-commit and push your changes

I don't understand your question...

If you want to redirect every request to a subfolder:

RewriteRule ^(.*)$ shop/$1 [L,QSA]

http://www.example.com/* -> wwwroot/store/*

If you want to redirect to a subfolder which has the domain name

RewriteCond %{HTTP_HOST} ([^\.]+\.[^\.]+)$
RewriteRule ^(.*)$ %1/$1 [L,QSA]

http://www.example.com/* -> wwwroot/example.com/*

I use filter

.filter('toDate', function() {
  return function(items) {
    return new Date(items);
  };
});

then

{{'2018-05-06 09:04:13' | toDate | date:'dd/MM/yyyy hh:mm'}}

Set IIS to forward your mail to the remote server. The specifics vary greatly depending on the version of IIS. For IIS 7.5:

1. Open IIS Manager
2. Connect to your server if needed
3. Select the server node; you should see an SMTP option on the right in the ASP.NET section
4. Double-click the SMTP icon.
5. Select the "Deliver e-mail to SMTP server" option and enter your server name, credentials, etc.

Try this if you are on ubuntu:

sudo apt-get update
sudo apt-get install build-essential libpq-dev libssl-dev openssl libffi-dev zlib1g-dev
sudo apt-get install python3-pip python3.7-dev
sudo apt-get install python3.7

In case you don't have the repository and so it fires a not-found package you first have to install this:

sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update

I was doing some testing and got this:

class A {
  public $property;
}

function set_property($obj) {
  $obj->property = "after";
  var_dump($obj);
}

$a = new A();
$a->property = "before";

// Creates a new Object from $a. Like "new A();"
$b = new $a;
// Makes a Copy of var $a, not referenced.
$c = clone $a;

set_property($a);
// object(A)#1 (1) { ["property"]=> string(5) "after" }

var_dump($a); // Because function set_property get by reference
// object(A)#1 (1) { ["property"]=> string(5) "after" }
var_dump($b);
// object(A)#2 (1) { ["property"]=> NULL }
var_dump($c);
// object(A)#3 (1) { ["property"]=> string(6) "before" }

// Now creates a new obj A and passes to the function by clone (will copied)
$d = new A();
$d->property = "before";

set_property(clone $d); // A new variable was created from $d, and not made a reference
// object(A)#5 (1) { ["property"]=> string(5) "after" }

var_dump($d);
// object(A)#4 (1) { ["property"]=> string(6) "before" }

?>

For Python, I haven't found an OpenCV function that provides contrast. As others have suggested, there are some techniques to automatically increase contrast using a very simple formula.

In the official OpenCV docs, it is suggested that this equation can be used to apply both contrast and brightness at the same time:

new_img = alpha*old_img + beta

where alpha corresponds to a contrast and beta is brightness. Different cases

alpha 1  beta 0      --> no change  
0 < alpha < 1        --> lower contrast  
alpha > 1            --> higher contrast  
-127 < beta < +127   --> good range for brightness values

In C/C++, you can implement this equation using cv::Mat::convertTo, but we don't have access to that part of the library from Python. To do it in Python, I would recommend using the cv::addWeighted function, because it is quick and it automatically forces the output to be in the range 0 to 255 (e.g. for a 24 bit color image, 8 bits per channel). You could also use convertScaleAbs as suggested by @nathancy.

import cv2
img = cv2.imread('input.png')
# call addWeighted function. use beta = 0 to effectively only operate one one image
out = cv2.addWeighted( img, contrast, img, 0, brightness)
output = cv2.addWeighted

The above formula and code is quick to write and will make changes to brightness and contrast. But they yield results that are significantly different than photo editing programs. The rest of this answer will yield a result that will reproduce the behavior in the GIMP and also LibreOffice brightness and contrast. It's more lines of code, but it gives a nice result.

Contrast

In the GIMP, contrast levels go from -127 to +127. I adapted the formulas from here to fit in that range.

f = 131*(contrast + 127)/(127*(131-contrast))
new_image = f*(old_image - 127) + 127 = f*(old_image) + 127*(1-f)

To figure out brightness, I figured out the relationship between brightness and levels and used information in this levels post to arrive at a solution.

#pseudo code
if brightness > 0
    shadow = brightness
    highlight = 255
else:
    shadow = 0
    highlight = 255 + brightness
new_img = ((highlight - shadow)/255)*old_img + shadow

brightness and contrast in Python and OpenCV

Putting it all together and adding using the reference "mandrill" image from USC SIPI:

import cv2
import numpy as np

# Open a typical 24 bit color image. For this kind of image there are
# 8 bits (0 to 255) per color channel
img = cv2.imread('mandrill.png')  # mandrill reference image from USC SIPI

s = 128
img = cv2.resize(img, (s,s), 0, 0, cv2.INTER_AREA)

def apply_brightness_contrast(input_img, brightness = 0, contrast = 0):
    
    if brightness != 0:
        if brightness > 0:
            shadow = brightness
            highlight = 255
        else:
            shadow = 0
            highlight = 255 + brightness
        alpha_b = (highlight - shadow)/255
        gamma_b = shadow
        
        buf = cv2.addWeighted(input_img, alpha_b, input_img, 0, gamma_b)
    else:
        buf = input_img.copy()
    
    if contrast != 0:
        f = 131*(contrast + 127)/(127*(131-contrast))
        alpha_c = f
        gamma_c = 127*(1-f)
        
        buf = cv2.addWeighted(buf, alpha_c, buf, 0, gamma_c)

    return buf


font = cv2.FONT_HERSHEY_SIMPLEX
fcolor = (0,0,0)

blist = [0, -127, 127,   0,  0, 64] # list of brightness values
clist = [0,    0,   0, -64, 64, 64] # list of contrast values


out = np.zeros((s*2, s*3, 3), dtype = np.uint8)

for i, b in enumerate(blist):
    c = clist[i]
    print('b, c:  ', b,', ',c)
    row = s*int(i/3)
    col = s*(i%3)
    
    print('row, col:   ', row, ', ', col)
    
    out[row:row+s, col:col+s] = apply_brightness_contrast(img, b, c)
    msg = 'b %d' % b
    cv2.putText(out,msg,(col,row+s-22), font, .7, fcolor,1,cv2.LINE_AA)
    msg = 'c %d' % c
    cv2.putText(out,msg,(col,row+s-4), font, .7, fcolor,1,cv2.LINE_AA)
    
    cv2.putText(out, 'OpenCV',(260,30), font, 1.0, fcolor,2,cv2.LINE_AA)

cv2.imwrite('out.png', out)

I manually processed the images in the GIMP and added text tags in Python/OpenCV:

Note: @UtkarshBhardwaj has suggested that Python 2.x users must cast the contrast correction calculation code into float for getting floating result, like so:

...
if contrast != 0:
        f = float(131*(contrast + 127))/(127*(131-contrast))
...

Java definitively has no structs :) But what you describe here looks like a JavaBean kind of class.

This can be done by using intents too:

  final Intent intent = new Intent(Intent.ACTION_VIEW,
    Uri.parse(
            "http://maps.google.com/maps?" +
            "saddr="+YOUR_START_LONGITUDE+","+YOUR_START_LATITUDE+"&daddr="YOUR_END_LONGITUDE+","+YOUR_END_LATITUDE));
         intent.setClassName(
          "com.google.android.apps.maps",
          "com.google.android.maps.MapsActivity");
   startActivity(intent);

There are few problems with the S3/Redirect based approach mentioned by others.

1. Mutliple redirects happen as your app's paths are resolved. For example: www.myapp.com/path/for/test gets redirected as www.myapp.com/#/path/for/test
2. There is a flicker in the url bar as the '#' comes and goes due the action of your SPA framework.
3. The seo is impacted because - 'Hey! Its google forcing his hand on redirects'
4. Safari support for your app goes for a toss.

The solution is:

1. Make sure you have the index route configured for your website. Mostly it is index.html
2. Remove routing rules from S3 configurations
3. Put a Cloudfront in front of your S3 bucket.

4. Configure error page rules for your Cloudfront instance. In the error rules specify:

   • Http error code: 404 (and 403 or other errors as per need)
   • Error Caching Minimum TTL (seconds) : 0
   • Customize response: Yes
   • Response Page Path : /index.html

   • HTTP Response Code: 200

     5. For SEO needs + making sure your index.html does not cache, do the following:

   • Configure an EC2 instance and setup an nginx server.

   • Assign a public ip to your EC2 instance.
   • Create an ELB that has the EC2 instance you created as an instance
   • You should be able to assign the ELB to your DNS.
   • Now, configure your nginx server to do the following things: Proxy_pass all requests to your CDN (for index.html only, serve other assets directly from your cloudfront) and for search bots, redirect traffic as stipulated by services like Prerender.io

I can help in more details with respect to nginx setup, just leave a note. Have learnt it the hard way.

Once the cloud front distribution update. Invalidate your cloudfront cache once to be in the pristine mode. Hit the url in the browser and all should be good.

There might two issues

1) $blogs may be a stdObject

or

2) The properties of the array might be the stdObject

Try using var_dump($blogs) and see the actual problem if the properties of array have stdObject try like this

$blog->id;
$blog->content;
$blog->title;

If you have just added FCM to an existing app, onTokenRefresh() will NOT be called. I got it to run by uninstalling the app and installing it again.

You are trying to compare strings inside an arithmetic command (((...))). Use [[ instead.

if [[ $username == "$username1" && $password == "$password1" ]] ||
   [[ $username == "$username2" && $password == "$password2" ]]; then

Note that I've reduced this to two separate tests joined by ||, with the && moved inside the tests. This is because the shell operators && and || have equal precedence and are simply evaluated from left to right. As a result, it's not generally true that a && b || c && d is equivalent to the intended ( a && b ) || ( c && d ).

Twine is an open-source tool for telling interactive, nonlinear stories. It generates a single html with multiples pages. Maybe it is not the right tool for you but it could be useful for someone else looking for something similar.

Know it's an old post. But these issues still exist.

Here are some of my findings on the subject, grossly explained.

"Status" 0 means one of 3 things, as per the XMLHttpRequest spec:

• dns name resolution failed (that's for instance when network plug is pulled out)

• server did not answer (a.k.a. unreachable or unresponding)

• request was aborted because of a CORS issue (abortion is performed by the user-agent and follows a failing OPTIONS pre-flight).

If you want to go further, dive deep into the inners of XMLHttpRequest. I suggest reading the ready-state update sequence ([0,1,2,3,4] is the normal sequence, [0,1,4] corresponds to status 0, [0,1,2,4] means no content sent which may be an error or not). You may also want to attach listeners to the xhr (onreadystatechange, onabort, onerror, ontimeout) to figure out details.

From the spec (XHR Living spec):

const unsigned short UNSENT = 0;
const unsigned short OPENED = 1;
const unsigned short HEADERS_RECEIVED = 2;
const unsigned short LOADING = 3;
const unsigned short DONE = 4;

You could also try to enable long file paths.

If you run Windows 10 Home Edition you could change your Registry to enable long paths.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem in regedit and then set LongPathsEnabled to 1.

If you have Windows 10 Pro or Enterprise you could also use Local Group Policies.

Go to Computer Configuration ? Administrative Templates ? System ? Filesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.

{{value | number : fractionSize}}

like {{12.52311 | number : 2}}

so this will print 12.52

I dont know about XamGrid but that's what i'll do with a standard wpf DataGrid:

<DataGrid>
    <DataGrid.Columns>
        <DataGridTemplateColumn>
            <DataGridTemplateColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellTemplate>
            <DataGridTemplateColumn.CellEditingTemplate>
                <DataTemplate>
                    <TextBox Text="{Binding DataContext.MyProperty, RelativeSource={RelativeSource AncestorType=MyUserControl}}"/>
                </DataTemplate>
            </DataGridTemplateColumn.CellEditingTemplate>
        </DataGridTemplateColumn>
    </DataGrid.Columns>
</DataGrid>

Since the TextBlock and the TextBox specified in the cell templates will be part of the visual tree, you can walk up and find whatever control you need.

I'd say stick to comma as it's widely recognized and understood. Be sure to quote your values and escape your quotes though.

ID,NAME,AGE
"23434","Norris, Chuck","24"
"34343","Bond, James ""master""","57"

I found a way to do it without creating your own images. In other words, the system image is being scaled. I don't pretend that the solution is perfect; if anyone knows a way to shorten some of the steps, I'll be happy to find out how.

First, I put the following in the main activity class of the project (WonActivity) . This was taken directly from Stack Overflow -- thank you guys!

/** get the default drawable for the check box */
Drawable getDefaultCheckBoxDrawable()
{
  int resID = 0;

  if (Build.VERSION.SDK_INT <= 10)
  {
    // pre-Honeycomb has a different way of setting the CheckBox button drawable
    resID = Resources.getSystem().getIdentifier("btn_check", "drawable", "android");
  }
  else
  {
    // starting with Honeycomb, retrieve the theme-based indicator as CheckBox button drawable
    TypedValue value = new TypedValue();
    getApplicationContext().getTheme().resolveAttribute(android.R.attr.listChoiceIndicatorMultiple, value, true);
    resID = value.resourceId;
  }

  return getResources().getDrawable(resID);
}

Second, I created a class to "scale a drawable". Please notice that it is completely different from the standard ScaleDrawable.

import android.graphics.drawable.*;

/** The drawable that scales the contained drawable */

public class ScalingDrawable extends LayerDrawable
{
  /** X scale */
  float scaleX;

  /** Y scale */
  float scaleY;

  ScalingDrawable(Drawable d, float scaleX, float scaleY)
  {
    super(new Drawable[] { d });
    setScale(scaleX, scaleY);
  }

  ScalingDrawable(Drawable d, float scale)
  {
    this(d, scale, scale);
  }

  /** set the scales */
  void setScale(float scaleX, float scaleY)
  {
    this.scaleX = scaleX;
    this.scaleY = scaleY;
  }

  /** set the scale -- proportional scaling */
  void setScale(float scale)
  {
    setScale(scale, scale);
  }

  // The following is what I wrote this for!

  @Override
  public int getIntrinsicWidth()
  {
    return (int)(super.getIntrinsicWidth() * scaleX);
  }

  @Override
  public int getIntrinsicHeight()
  {
    return (int)(super.getIntrinsicHeight() * scaleY);
  }
}

Finally, I defined a checkbox class.

import android.graphics.*;
import android.graphics.drawable.Drawable;
import android.widget.*;

/** A check box that resizes itself */

public class WonCheckBox extends CheckBox
{
  /** the check image */
  private ScalingDrawable checkImg;

  /** original height of the check-box image */
  private int origHeight;

  /** original padding-left */
  private int origPadLeft;

  /** height set by the user directly */
  private float height;

  WonCheckBox()
  {
    super(WonActivity.W.getApplicationContext());
    setBackgroundColor(Color.TRANSPARENT);

    // get the original drawable and get its height
    Drawable origImg = WonActivity.W.getDefaultCheckBoxDrawable();
    origHeight = height = origImg.getIntrinsicHeight();
    origPadLeft = getPaddingLeft();

    // I tried origImg.mutate(), but that fails on Android 2.1 (NullPointerException)
    checkImg = new ScalingDrawable(origImg, 1);
    setButtonDrawable(checkImg);
  }

  /** set checkbox height in pixels directly */
  public void setHeight(int height)
  {
    this.height = height;
    float scale = (float)height / origHeight;
    checkImg.setScale(scale);

    // Make sure the text is not overlapping with the image.
    // This is unnecessary on Android 4.2.2, but very important on previous versions.
    setPadding((int)(scale * origPadLeft), 0, 0, 0);

    // call the checkbox's internal setHeight()
    //   (may be unnecessary in your case)
    super.setHeight(height);
  }
}

That's it. If you put a WonCheckBox in your view and apply setHeight(), the check-box image will be of the right size.

This shows only date:

$('#myDateTimePicker').datetimepicker({
        format: 'dd.mm.yyyy',
        minView: 2,
        maxView: 4,
        autoclose: true
      });

More on the subject here

You can use the SimpleDateFormat class:

SimpleDateFormat s = new SimpleDateFormat("ddMMyyyyhhmmss");
String format = s.format(new Date());

Use perl -i, with a command that replaces the beginning of line 1 with what you want to insert (the .bk will have the effect that your original file is backed up):

perl -i.bk -pe 's/^/column1, column2, column3\n/ if($.==1)' testfile.csv  

There is a way to do this without clearing the canvas or starting over, but you have to man handle the creation of the chart so that the data is in the same format for when you update.

Here is how I did it.

    var ctx = document.getElementById("myChart").getContext("2d");
    if (chartExists) {
        for (i=0;i<10;i++){
            myNewChart.scale.xLabels[i]=dbLabels[i]; 
            myNewChart.datasets[0].bars[i].value=dbOnAir[i];
        }
        myNewChart.update();
      }else{
          console.log('chart doesnt exist');
          myNewChart = new Chart(ctx).Bar(dataNew);
          myNewChart.removeData();
          for (i=0;i<10;i++){
              myNewChart.addData([10],dbLabels[i]);
          }
          for (i=0;i<10;i++){      
              myNewChart.datasets[0].bars[i].value=dbOnAir[i];
          }
          myNewChart.update();
          chartExists=true;
        }

I basically scrap the data loaded in at creation, and then reform with the add data method. This means that I can then access all the points. Whenever I have tried to access the data structure that is created by the:

Chart(ctx).Bar(dataNew);

command, I can't access what I need. This means you can change all the data points, in the same way you created them, and also call update() without animating completely from scratch.

I think, the difference is in usage patterns.

I would prefer .on over .click because the former can use less memory and work for dynamically added elements.

Consider the following html:

<html>
    <button id="add">Add new</button>
    <div id="container">
        <button class="alert">alert!</button>
    </div>
</html>

where we add new buttons via

$("button#add").click(function() {
    var html = "<button class='alert'>Alert!</button>";
    $("button.alert:last").parent().append(html);
});

and want "Alert!" to show an alert. We can use either "click" or "on" for that.

When we use click

$("button.alert").click(function() {
    alert(1);
});

with the above, a separate handler gets created for every single element that matches the selector. That means

1. many matching elements would create many identical handlers and thus increase memory footprint
2. dynamically added items won't have the handler - ie, in the above html the newly added "Alert!" buttons won't work unless you rebind the handler.

When we use .on

$("div#container").on('click', 'button.alert', function() {
    alert(1);
});

with the above, a single handler for all elements that match your selector, including the ones created dynamically.

...another reason to use .on

As Adrien commented below, another reason to use .on is namespaced events.

If you add a handler with .on("click", handler) you normally remove it with .off("click", handler) which will remove that very handler. Obviously this works only if you have a reference to the function, so what if you don't ? You use namespaces:

$("#element").on("click.someNamespace", function() { console.log("anonymous!"); });

with unbinding via

$("#element").off("click.someNamespace");

private void button1_Click(object sender, EventArgs e)
{
      Form2 m = new Form2();
      m.Show();
      this.Visible = false;
}

1. Go to Settings -> Debugger -> Common -> GDB/CDB Debugger -> Default
2. Click on executable path to find the address to gdb32.exe
3. Locate where your codeblock is installed
4. Follow the given path:

CodeBlock -> MinGW -> bin -> gdb32.exe (locate it and double click on it)

5. Press OK

If you want to limit memory for jvm (not the heap size ) ulimit -v

To get an idea of the difference between jvm and heap memory , take a look at this excellent article http://blogs.vmware.com/apps/2011/06/taking-a-closer-look-at-sizing-the-java-process.html

A common and simple solution to this problem that feels like a hack but is fairly portable is to add a randomly generated query string to each request for the dynamic image.

So, for example -

<img src="image.png" />

Would become

<img src="image.png?dummy=8484744" />

Or

<img src="image.png?dummy=371662" />

From the point of view of the web-server the same file is accessed, but from the point of view of the browser no caching can be performed.

The random number generation can happen either on the server when serving the page (just make sure the page itself isn't cached...), or on the client (using JavaScript).

You will need to verify whether your web-server can cope with this trick.

JoshAdel's solution uses np.newaxis to add a dimension. An alternative is to use reshape() to align the dimensions in preparation for broadcasting.

data = np.array([[1,1,1],[2,2,2],[3,3,3]])
vector = np.array([1,2,3])

data
# array([[1, 1, 1],
#        [2, 2, 2],
#        [3, 3, 3]])
vector
# array([1, 2, 3])

data.shape
# (3, 3)
vector.shape
# (3,)

data / vector.reshape((3,1))
# array([[1, 1, 1],
#        [1, 1, 1],
#        [1, 1, 1]])

Performing the reshape() allows the dimensions to line up for broadcasting:

data:            3 x 3
vector:              3
vector reshaped: 3 x 1

Note that data/vector is ok, but it doesn't get you the answer that you want. It divides each column of array (instead of each row) by each corresponding element of vector. It's what you would get if you explicitly reshaped vector to be 1x3 instead of 3x1.

data / vector
# array([[1, 0, 0],
#        [2, 1, 0],
#        [3, 1, 1]])
data / vector.reshape((1,3))
# array([[1, 0, 0],
#        [2, 1, 0],
#        [3, 1, 1]])

VB6: Listview1.selecteditem

VB10: Listview1.FocusedItem.Text

Take a look at http://dev.mysql.com/doc/refman/5.0/en/declare-handler.html

Basically you declare error handler which will call rollback

START TRANSACTION;

DECLARE EXIT HANDLER FOR SQLEXCEPTION 
    BEGIN
        ROLLBACK;
        EXIT PROCEDURE;
    END;
COMMIT;

Storm's answer is not correct. No hard feelings Storm, and apologies to the OP as I'm a bit late to the party here (wish I could have helped sooner, but I didn't run into the problem until today, or this stack overflow answer until I was figuring out a solution.)

The Visual C++ 2003 runtime was not available as a seperate download because it was included with the .NET 1.1 runtime.

If you install the .NET 1.1 runtime you will get msvcr71.dll installed, and in addition added to C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322.

The .NET 1.1 runtime is available here: http://www.microsoft.com/downloads/en/details.aspx?familyid=262d25e3-f589-4842-8157-034d1e7cf3a3&displaylang=en (23.1 MB)

If you are looking for a file that ends with a "P" such as msvcp71.dll, this indicates that your file was compiled against a C++ runtime (as opposed to a C runtime), in some situations I noticed these files were only installed when I installed the full SDK. If you need one of these files, you may need to install the full .NET 1.1 SDK as well, which is available here: http://www.microsoft.com/downloads/en/details.aspx?FamilyID=9b3a2ca6-3647-4070-9f41-a333c6b9181d (106.2 MB)

After installing the SDK I now have both msvcr71.dll and msvcp71.dll in my System32 folder, and the application I'm trying to run (boomerang c++ decompiler) works fine without any missing DLL errors.

Also on a side note: be VERY aware of the difference between a Hotfix Update and a Regular Update. As noted in the linked KB932298 download (linked below by Storm): "Please be aware this Hotfix has not gone through full Microsoft product regression testing nor has it been tested in combination with other Hotfixes."

Hotfixes are NOT meant for general users, but rather users who are facing a very specific problem. As described in the article only install that Hotfix if you are have having specific daylight savings time issues with the rules that changed in 2007. -- Likely this was a pre-release for customers who "just couldn't wait" for the official update (probably for some business critical application) -- for regular users Windows Update should be all you need.

Thanks, and I hope this helps others who run into this issue!

Check if bit N (starting from 0) is set:

temp & (1 << N)

There is no builtin function for this.

Or just use a fake-git-history to generate it for a specific data range.

Wikipedia tells what comma operator does:

"In the C and C++ programming languages, the comma operator (represented by the token ,) is a binary operator that evaluates its first operand and discards the result, and then evaluates the second operand and returns this value (and type)."

When i have large bitmaps and i want to decode them resized i use the following

BitmapFactory.Options options = new BitmapFactory.Options();
InputStream is = null;
is = new FileInputStream(path_to_file);
BitmapFactory.decodeStream(is,null,options);
is.close();
is = new FileInputStream(path_to_file);
// here w and h are the desired width and height
options.inSampleSize = Math.max(options.outWidth/w, options.outHeight/h);
// bitmap is the resized bitmap
Bitmap bitmap = BitmapFactory.decodeStream(is,null,options);

The solution is increasing the values given the wait_timeout and the connect_timeout parameters in your options file, under the [mysqld] tag.

I had to recover a 400MB mysql backup and this worked for me (the values I've used below are a bit exaggerated, but you get the point):

[mysqld]
port=3306
explicit_defaults_for_timestamp = TRUE
connect_timeout = 1000000
net_write_timeout = 1000000
wait_timeout = 1000000
max_allowed_packet = 1024M
interactive_timeout = 1000000
net_buffer_length = 200M
net_read_timeout = 1000000
set GLOBAL delayed_insert_timeout=100000

Blockquote

can use

border-width:2px;
border-style:solid;
border-color:black;

or as shorthand

border: 2px solid black

As long as your layout in your cell is good.

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];

    return [cell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height;
}

Update: You should use dynamic resizing introduced in iOS 8.

use:

/^[ A-Za-z0-9_@./#&+-]*$/

You can also use the character class \w to replace A-Za-z0-9_

You can use the relative location of the saved pdf like this:

Example1

<embed src="example.pdf" width="1000" height="800" frameborder="0" allowfullscreen>

Example2

<iframe src="example.pdf" style="width:1000px; height:800px;" frameborder="0" allowfullscreen></iframe>

Instead of using

response.sendRedirect("/demo.jsp");

Which does a permanent redirect to an absolute URL path,

Rather use RequestDispatcher. Example:

RequestDispatcher dispatcher = request.getRequestDispatcher("demo.jsp");
dispatcher.forward(request, response);

php_value upload_max_filesize 30M is correct.

You will have to contact your hosters -- some don't allow you to change values in php.ini

A quick google indicates that pwdencrypt() is not deterministic, and your statement select pwdencrypt('AAAA') returns a different value on my installation!

Best one

String str_date=month+"-"+day+"-"+yr;
DateFormat formatter = new SimpleDateFormat("MM-dd-yyyy");
Date date = (Date)formatter.parse(str_date); 
long output=date.getTime()/1000L;
String str=Long.toString(output);
long timestamp = Long.parseLong(str) * 1000;

In addition to the above, you can do this (where "YourListObjectName" is the name of your table):

Dim LO As ListObject
Set LO = ActiveSheet.ListObjects("YourListObjectName")

But I think that only works if you want to reference a list object that's on the active sheet.

I found your question because I wanted to refer to a list object (a table) on one worksheet that a pivot table on a different worksheet refers to. Since list objects are part of the Worksheets collection, you have to know the name of the worksheet that list object is on in order to refer to it. So to get the name of the worksheet that the list object is on, I got the name of the pivot table's source list object (again, a table) and looped through the worksheets and their list objects until I found the worksheet that contained the list object I was looking for.

Public Sub GetListObjectWorksheet()
' Get the name of the worksheet that contains the data
' that is the pivot table's source data.

    Dim WB As Workbook
    Set WB = ActiveWorkbook

    ' Create a PivotTable object and set it to be
    ' the pivot table in the active cell:
    Dim PT As PivotTable
    Set PT = ActiveCell.PivotTable

    Dim LO As ListObject
    Dim LOWS As Worksheet

    ' Loop through the worksheets and each worksheet's list objects
    ' to find the name of the worksheet that contains the list object
    ' that the pivot table uses as its source data:
    Dim WS As Worksheet
    For Each WS In WB.Worksheets
        ' Loop through the ListObjects in each workshet:
        For Each LO In WS.ListObjects
            ' If the ListObject's name is the name of the pivot table's soure data,
            ' set the LOWS to be the worksheet that contains the list object:
            If LO.Name = PT.SourceData Then
                Set LOWS = WB.Worksheets(LO.Parent.Name)
            End If
        Next LO
    Next WS

    Debug.Print LOWS.Name

End Sub

Maybe someone knows a more direct way.

This has bugged me for some time. What I usually end up doing is rebuilding my external library using debug mode, then copy both .dll and the .pdb file to the bin of my website. This allows me to step into the libarary code.

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

This saves the absolute path of the current working directory to the variable cwd:

cwd=$(pwd)

In your case you can just do:

export PATH=$PATH:$(pwd)+somethingelse

Connect to your server via SSH

then connect to your mysql console

and

USE user_base
REPAIR TABLE TABLE;

-OR-

If there are a lot of broken tables in current database:

mysqlcheck -uUSER -pPASSWORD  --repair --extended user_base

If there are a lot of broken tables in a lot of databases:

mysqlcheck -uUSER -pPASSWORD  --repair --extended -A

SQLAlchemy upsert for Postgres >=9.5

Since the large post above covers many different SQL approaches for Postgres versions (not only non-9.5 as in the question), I would like to add how to do it in SQLAlchemy if you are using Postgres 9.5. Instead of implementing your own upsert, you can also use SQLAlchemy's functions (which were added in SQLAlchemy 1.1). Personally, I would recommend using these, if possible. Not only because of convenience, but also because it lets PostgreSQL handle any race conditions that might occur.

Cross-posting from another answer I gave yesterday (https://stackoverflow.com/a/44395983/2156909)

SQLAlchemy supports ON CONFLICT now with two methods on_conflict_do_update() and on_conflict_do_nothing():

Copying from the documentation:

from sqlalchemy.dialects.postgresql import insert

stmt = insert(my_table).values(user_email='[email protected]', data='inserted data')
stmt = stmt.on_conflict_do_update(
    index_elements=[my_table.c.user_email],
    index_where=my_table.c.user_email.like('%@gmail.com'),
    set_=dict(data=stmt.excluded.data)
    )
conn.execute(stmt)

http://docs.sqlalchemy.org/en/latest/dialects/postgresql.html?highlight=conflict#insert-on-conflict-upsert

There are two pages: Pageone.html :

<script>
var hello = "hi"
location.replace("http://example.com/PageTwo.html?" + hi + "");
</script>

PageTwo.html :

<script>
var link = window.location.href;
link = link.replace("http://example.com/PageTwo.html?","");
document.write("The variable contained this content:" + link + "");
</script>

Hope it helps!
