The html() function can take strings of HTML, and will effectively modify the .innerHTML property.

$('#regTitle').html('Hello World');

However, the text() function will change the (text) value of the specified element, but keep the html structure.

$('#regTitle').text('Hello world'); 

Wouldn't a normal foreach basically yield the same result as a mysql_fetch_assoc in your case?

when using foreach on that array, you would get an array containing those three keys: 'id','firstname' and 'lastname'.

That should be the same as mysql_fetch_assoc would give (in a loop) for each row.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

I have make an addition to @AbraCadaver answers. I have included a javascript script which will delete php starting and closing tag. We will have clean more pretty dump.

May be somebody like this too.

function dd($data){
  highlight_string("<?php\n " . var_export($data, true) . "?>");
  echo '<script>document.getElementsByTagName("code")[0].getElementsByTagName("span")[1].remove() ;document.getElementsByTagName("code")[0].getElementsByTagName("span")[document.getElementsByTagName("code")[0].getElementsByTagName("span").length - 1].remove() ; </script>';
  die();
}

Result before:

Result After:

Now we don't have php starting and closing tag

I tried installing the module locally with version and it worked!!

npm install request@^2.*

Thanks.

See ?nchar. For example:

> nchar("foo")
[1] 3
> set.seed(10)
> strn <- paste(sample(LETTERS, 10), collapse = "")
> strn
[1] "NHKPBEFTLY"
> nchar(strn)
[1] 10

Here is the way to go:

Runtime rt = Runtime.getRuntime();
String[] commands = {"system.exe", "-get t"};
Process proc = rt.exec(commands);

BufferedReader stdInput = new BufferedReader(new 
     InputStreamReader(proc.getInputStream()));

BufferedReader stdError = new BufferedReader(new 
     InputStreamReader(proc.getErrorStream()));

// Read the output from the command
System.out.println("Here is the standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
    System.out.println(s);
}

// Read any errors from the attempted command
System.out.println("Here is the standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
    System.out.println(s);
}

Read the Javadoc for more details here. ProcessBuilder would be a good choice to use.

Follow these Steps:

1: Enter:

git reflog show 

This will display all the Commit history, you need to select the sha-1 that has the last commit that you want to get back

2: create a branch name with the Sha-1 ID you selected eg: 8c87714

git branch your-branch-name 8c87714

There is no "second property" -- when you say var obj = { ... }, the properties inside the braces are unordered. Even a 'for' loop walking through them might return them in different orders on different JavaScript implementations.

If you know how PDF files are structured (or are willing to spend a little while reading the spec), you can do it this way.

Use the Named Action "Print" in the OpenAction field of the Catalog object; the "Print" action is undocumented, but Acrobat Reader and most of the other major readers understand it. A nice benefit of this approach is that you don't get any JavaScript warnings. See here for details: http://www.gnostice.com/nl_article.asp?id=157

To make it even shinier, I added a second Action, URI, directing the reader to go back to the page that originated the request. Then I attached this Action to the first Named action using its Next field. With content disposition set to "inline", this makes it so that when the user clicks on the print link:

1. It opens up Adobe Reader in the same tab and loads the file
2. It immediately shows the print dialog
3. As soon as the Print dialog is closed (whether they hit "OK" or "cancel"), the browser tab goes back to the webpage

I was able to do all these changes in Ruby easily enough using only the File and IO modules; I opened the PDF I had generated with an external tool, followed the xref to the existing Catalog section, then appended a new section onto the PDF with an updated Catalog object containing my special OpenAction line, and also the new Action objects.

Because of PDF's incremental revision features, you don't have to make any changes to the existing data to do this, just append an additional section to the end.

MySQL 8.0 now supports windowing functions, like almost all popular SQL implementations. With this standard syntax, we can write greatest-n-per-group queries:

WITH ranked_messages AS (
  SELECT m.*, ROW_NUMBER() OVER (PARTITION BY name ORDER BY id DESC) AS rn
  FROM messages AS m
)
SELECT * FROM ranked_messages WHERE rn = 1;

Below is the original answer I wrote for this question in 2009:

I write the solution this way:

SELECT m1.*
FROM messages m1 LEFT JOIN messages m2
 ON (m1.name = m2.name AND m1.id < m2.id)
WHERE m2.id IS NULL;

Regarding performance, one solution or the other can be better, depending on the nature of your data. So you should test both queries and use the one that is better at performance given your database.

For example, I have a copy of the StackOverflow August data dump. I'll use that for benchmarking. There are 1,114,357 rows in the Posts table. This is running on MySQL 5.0.75 on my Macbook Pro 2.40GHz.

I'll write a query to find the most recent post for a given user ID (mine).

First using the technique shown by @Eric with the GROUP BY in a subquery:

SELECT p1.postid
FROM Posts p1
INNER JOIN (SELECT pi.owneruserid, MAX(pi.postid) AS maxpostid
            FROM Posts pi GROUP BY pi.owneruserid) p2
  ON (p1.postid = p2.maxpostid)
WHERE p1.owneruserid = 20860;

1 row in set (1 min 17.89 sec)

Even the EXPLAIN analysis takes over 16 seconds:

+----+-------------+------------+--------+----------------------------+-------------+---------+--------------+---------+-------------+
| id | select_type | table      | type   | possible_keys              | key         | key_len | ref          | rows    | Extra       |
+----+-------------+------------+--------+----------------------------+-------------+---------+--------------+---------+-------------+
|  1 | PRIMARY     | <derived2> | ALL    | NULL                       | NULL        | NULL    | NULL         |   76756 |             | 
|  1 | PRIMARY     | p1         | eq_ref | PRIMARY,PostId,OwnerUserId | PRIMARY     | 8       | p2.maxpostid |       1 | Using where | 
|  2 | DERIVED     | pi         | index  | NULL                       | OwnerUserId | 8       | NULL         | 1151268 | Using index | 
+----+-------------+------------+--------+----------------------------+-------------+---------+--------------+---------+-------------+
3 rows in set (16.09 sec)

Now produce the same query result using my technique with LEFT JOIN:

SELECT p1.postid
FROM Posts p1 LEFT JOIN posts p2
  ON (p1.owneruserid = p2.owneruserid AND p1.postid < p2.postid)
WHERE p2.postid IS NULL AND p1.owneruserid = 20860;

1 row in set (0.28 sec)

The EXPLAIN analysis shows that both tables are able to use their indexes:

+----+-------------+-------+------+----------------------------+-------------+---------+-------+------+--------------------------------------+
| id | select_type | table | type | possible_keys              | key         | key_len | ref   | rows | Extra                                |
+----+-------------+-------+------+----------------------------+-------------+---------+-------+------+--------------------------------------+

|  1 | SIMPLE      | p2    | ref  | PRIMARY,PostId,OwnerUserId | OwnerUserId | 8       | const | 1384 | Using where; Using index; Not exists | 
+----+-------------+-------+------+----------------------------+-------------+---------+-------+------+--------------------------------------+
2 rows in set (0.00 sec)

In a very simple logging scenario, where you're literally just trying to write to console during development for debugging purposes, it might be easiest to just do a search and replace before your production build and comment out all the calls to Log or System.out.println.

For example, assuming you didn't use the "Log." anywhere outside of a call to Log.d or Log.e, etc, you could simply do a find and replace across the entire solution to replace "Log." with "//Log." to comment out all your logging calls, or in my case I'm just using System.out.println everywhere, so before going to production I'll simply do a full search and replace for "System.out.println" and replace with "//System.out.println".

I know this isn't ideal, and it would be nice if the ability to find and comment out calls to Log and System.out.println were built into Eclipse, but until that happens the easiest and fastest and best way to do this is to comment out by search and replace. If you do this, you don't have to worry about mismatching stack trace line numbers, because you're editing your source code, and you're not adding any overhead by checking some log level configuration, etc.

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

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

Edit your package.json. Change:

"gulp-sass": "^2.3.2"

to

"gulp-sass": "3.0.0"

Delete the node_modules folder and run npm install again.

print_r() is mostly for debugging. If you want to print it in that format, loop through the array, and print the elements out.

foreach($data as $d){
  foreach($d as $v){
    echo $v."\n";
  }
}

If there are too many files to delete, which is actually a case for me. You can also try the following solution:

1) fetch

2) merge with a strategy. For instance this one works for me:

git.exe merge --strategy=ours master

Update to MySQL 8.0.16 to use checks:

As of MySQL 8.0.16, CREATE TABLE permits the core features of table and column CHECK constraints, for all storage engines. CREATE TABLE permits the following CHECK constraint syntax, for both table constraints and column constraints

If you want to convert an int which is in the range 0-9 to a char, you may usually write something like this:

int x;
char c = '0' + x;

Now, if you want a character string, just add a terminating '\0' char:

char s[] = {'0' + x, '\0'};

Note that:

1. You must be sure that the int is in the 0-9 range, otherwise it will fail,
2. It works only if character codes for digits are consecutive. This is true in the vast majority of systems, that are ASCII-based, but this is not guaranteed to be true in all cases.

I agree with previous opinions. It is good to say, that if you are going to share DbContext in single thread app, you'll need more memory. For example my web application on Azure (one extra small instance) needs another 150 MB of memory and I have about 30 users per hour.

Here is real example image: application have been deployed in 12PM

You may use Arrays.sort() function.

sort() method is a java.util.Arrays class method.          
Declaration : Arrays.sort(arrName)

We can create a new CSS class for div.

 .div {
      position: absolute;
      left: 150px;
      width: 200px;
      height: 120px;
    }

You can grant system privileges with or without the admin option. The default being without admin option.

GRANT CREATE SESSION TO username

or with admin option:

GRANT CREATE SESSION TO username WITH ADMIN OPTION

The Grantee with the ADMIN OPTION can grant and revoke privileges to other users

I hope this code will help someone - it is from official Google Firebase documentation:

var adaRef = firebase.database().ref('users/ada');
adaRef.remove()
  .then(function() {
    console.log("Remove succeeded.")
  })
  .catch(function(error) {
    console.log("Remove failed: " + error.message)
  });

Finding max and min value the easy and manual way. This code is much faster than Math.max.apply; I have tried up to 1000k numbers in array.

function findmax(array)
{
    var max = 0;
    var a = array.length;
    for (counter=0;counter<a;counter++)
    {
        if (array[counter] > max)
        {
            max = array[counter];
        }
    }
    return max;
}

function findmin(array)
{
    var min = array[0];
    var a = array.length;
    for (counter=0;counter<a;counter++)
    {
        if (array[counter] < min)
        {
            min = array[counter];
        }
    }
    return min;
}

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

Yes, main method can be overloaded. Overloaded main method has to be called from inside the "public static void main(String args[])" as this is the entry point when the class is launched by the JVM. Also overloaded main method can have any qualifier as a normal method have.

These names refers to different ways to encode pixel image data (JPG and JPEG are the same thing, and TIFF may just enclose a jpeg with some additional metadata).

These image formats may use different compression algorithms, different color representations, different capability in carrying additional data other than the image itself, and so on.

For web applications, I'd say jpeg or gif is good enough. Jpeg is used more often due to its higher compression ratio, and gif is typically used for light weight animation where a flash (or something similar) is an over kill, or places where transparent background is desired. PNG can be used too, but I don't have much experience with that. BMP and TIFF probably are not good candidates for web applications.

i++ is known as Post Increment whereas ++i is called Pre Increment.

i++

i++ is post increment because it increments i's value by 1 after the operation is over.

Lets see the following example:

int i = 1, j;
j = i++;

Here value of j = 1 but i = 2. Here value of i will be assigned to j first then i will be incremented.

++i

++i is pre increment because it increments i's value by 1 before the operation. It means j = i; will execute after i++.

Lets see the following example:

int i = 1, j;
j = ++i;

Here value of j = 2 but i = 2. Here value of i will be assigned to j after the i incremention of i. Similarly ++i will be executed before j=i;.

For your question which should be used in the incrementation block of a for loop? the answer is, you can use any one.. doesn't matter. It will execute your for loop same no. of times.

for(i=0; i<5; i++)
   printf("%d ",i);

And

for(i=0; i<5; ++i)
   printf("%d ",i);

Both the loops will produce same output. ie 0 1 2 3 4.

It only matters where you are using it.

for(i = 0; i<5;)
    printf("%d ",++i);

In this case output will be 1 2 3 4 5.

In simple words:

1. innerText will show the value as is and ignores any HTML formatting which may be included.
2. innerHTML will show the value and apply any HTML formatting.

Note that adjusting the width of a column in the thead will affect the whole table

<table>
    <thead>
        <tr width="25">
            <th>Name</th>
            <th>Email</th>
        </tr>
    </thead>
    <tr>
        <td>Joe</td>
        <td>[email protected]</td>
    </tr>
</table>

In my case, the width on the thead > tr was overriding the width on table > tr > td directly.

If the HTML is not XML you can't do it with etree. But even then, you don't have to use an external library for parsing a HTML table. In python 3 you can reach your goal with HTMLParser from html.parser. I've the code of the simple derived HTMLParser class here in a github repo.

You can use that class (here named HTMLTableParser) the following way:

import urllib.request
from html_table_parser import HTMLTableParser

target = 'http://www.twitter.com'

# get website content
req = urllib.request.Request(url=target)
f = urllib.request.urlopen(req)
xhtml = f.read().decode('utf-8')

# instantiate the parser and feed it
p = HTMLTableParser()
p.feed(xhtml)
print(p.tables)

The output of this is a list of 2D-lists representing tables. It looks maybe like this:

[[['   ', ' Anmelden ']],
 [['Land', 'Code', 'Für Kunden von'],
  ['Vereinigte Staaten', '40404', '(beliebig)'],
  ['Kanada', '21212', '(beliebig)'],
  ...
  ['3424486444', 'Vodafone'],
  ['  Zeige SMS-Kurzwahlen für andere Länder ']]]

On Ubuntu you can enable a cron.log file to contain just the CRON entries.

Uncomment the line that mentions cron in /etc/rsyslog.d/50-default.conf file:

#  Default rules for rsyslog.
#

#                       For more information see rsyslog.conf(5) and /etc/rsyslog.conf

#
# First some standard log files.  Log by facility.
#
auth,authpriv.*                 /var/log/auth.log
*.*;auth,authpriv.none          -/var/log/syslog
#cron.*                          /var/log/cron.log

Save and close the file and then restart the rsyslog service:

sudo systemctl restart rsyslog

You can now see cron log entries in its own file:

sudo tail -f /var/log/cron.log

Sample outputs:

Jul 18 07:05:01 machine-host-name CRON[13638]: (root) CMD (command -v debian-sa1 > /dev/null && debian-sa1 1 1)

However, you will not see more information about what scripts were actually run inside /etc/cron.daily or /etc/cron.hourly, unless those scripts direct output to the cron.log (or perhaps to some other log file).

If you want to verify if a crontab is running and not have to search for it in cron.log or syslog, create a crontab that redirects output to a log file of your choice - something like:

# For more information see the manual pages of crontab(5) and cron(8)
#
# m h  dom mon dow   command
30 2 * * 1 /usr/local/sbin/certbot-auto renew >> /var/log/le-renew.log 2>&1

Steps taken from: https://www.cyberciti.biz/faq/howto-create-cron-log-file-to-log-crontab-logs-in-ubuntu-linux/

Here is a very simple way (3 lines of code) using the Fullscreen API and RequestFullscreen method that I used, which is compatible across all popular browsers:

var elem = document.getElementsByTagName('video')[0];_x000D_
var fullscreen = elem.webkitRequestFullscreen || elem.mozRequestFullScreen || elem.msRequestFullscreen;_x000D_
fullscreen.call(elem); // bind the 'this' from the video object and instantiate the correct fullscreen method.

For browser compatibility: MDN & Can I use

Yes, it's possible to use inline if-expressions:

{{ 'Update' if files else 'Continue' }}

This is how I always do maths in Bash:

count=$(echo "$FIRSTV - $SECONDV"|bc)
echo $count

You got an extra } to many as seen below:

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        } // <-- REMOVE THIS :)
    }, false);
};

A very good tool for those things is jsFiddle. I have created a fiddle with your invalid code and when clicking the TidyUp button it formats your code which makes it clearer if there are any possible mistakes with missing braces.

DEMO - Your code in a fiddle, have a play :)

I know is old topic but what about simple solution like while loop?

int function count(array[]) {

    int i = 0;

    while(array[i] != NULL) {

        i++;

    }

    return i;

}

I know that is slower than sizeof() but this is another example of array count.

I used this code to solve this problem.

There are few typical methods how we control components render in React.

But, I haven't used any of these in here, I just used the ref's to namespace underlying children to the component.

class AddItem extends React.Component {_x000D_
    change(e) {_x000D_
      if ("" != e.target.value) {_x000D_
        this.button.disabled = false;_x000D_
      } else {_x000D_
        this.button.disabled = true;_x000D_
      }_x000D_
    }_x000D_
_x000D_
    add(e) {_x000D_
      console.log(this.input.value);_x000D_
      this.input.value = '';_x000D_
      this.button.disabled = true;_x000D_
    }_x000D_
_x000D_
    render() {_x000D_
        return (_x000D_
          <div className="add-item">_x000D_
          <input type="text" className = "add-item__input" ref = {(input) => this.input=input} onChange = {this.change.bind(this)} />_x000D_
          _x000D_
          <button className="add-item__button" _x000D_
          onClick= {this.add.bind(this)} _x000D_
          ref={(button) => this.button=button}>Add_x000D_
          </button>_x000D_
          </div>_x000D_
        );_x000D_
    }_x000D_

_x000D_

Nice article explaining the basics (does not cover line breaks, however).

A Whole Bunch of Amazing Stuff Pseudo Elements Can Do

If you need to have two inline elements where one breaks into the next line within another element, you can accomplish this by adding a pseudo-element :after with content:'\A' and white-space: pre

HTML

<h3>
    <span class="label">This is the main label</span>
    <span class="secondary-label">secondary label</span>
</h3>

CSS

.label:after {
    content: '\A';
    white-space: pre;
}

I do get the same information while debugging. Though not while I am checking the stacktrace. Most probably you would have used the optimization flag I think. Check this link - something related.

Try compiling with -g3 remove any optimization flag. Then it might work. HTH!

This problem isn't caused by missing tab stops; it's that emacs has a (new?) tab method called indent-relative that seems designed to line up tabular data. The TAB key is mapped to the method indent-for-tab-command, which calls whatever method the variable indent-line-function is set to, which is indent-relative method for text mode. I havn't figured out a good way to override the indent-line-function variable (text mode hook isn't working, so maybe it is getting reset after the mode-hooks run?) but one simple way to get rid of this behavior is to just chuck the intent-for-tab-command method by setting TAB to the simpler tab-to-tab-stop method:

(define-key text-mode-map (kbd "TAB") 'tab-to-tab-stop)

You should provide the second database information in `application/config/database.php´

Normally, you would set the default database group, like so:

$db['default']['hostname'] = "localhost";
$db['default']['username'] = "root";
$db['default']['password'] = "";
$db['default']['database'] = "database_name";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = FALSE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
$db['default']['swap_pre'] = "";
$db['default']['autoinit'] = TRUE;
$db['default']['stricton'] = FALSE;

Notice that the login information and settings are provided in the array named $db['default'].

You can then add another database in a new array - let's call it 'otherdb'.

$db['otherdb']['hostname'] = "localhost";
$db['otherdb']['username'] = "root";
$db['otherdb']['password'] = "";
$db['otherdb']['database'] = "other_database_name";
$db['otherdb']['dbdriver'] = "mysql";
$db['otherdb']['dbprefix'] = "";
$db['otherdb']['pconnect'] = TRUE;
$db['otherdb']['db_debug'] = FALSE;
$db['otherdb']['cache_on'] = FALSE;
$db['otherdb']['cachedir'] = "";
$db['otherdb']['char_set'] = "utf8";
$db['otherdb']['dbcollat'] = "utf8_general_ci";
$db['otherdb']['swap_pre'] = "";
$db['otherdb']['autoinit'] = TRUE;
$db['otherdb']['stricton'] = FALSE;

Now, to actually use the second database, you have to send the connection to another variabel that you can use in your model:

function my_model_method()
{
  $otherdb = $this->load->database('otherdb', TRUE); // the TRUE paramater tells CI that you'd like to return the database object.

  $query = $otherdb->select('first_name, last_name')->get('person');
  var_dump($query);
}

That should do it. The documentation for connecting to multiple databases can be found here: http://codeigniter.com/user_guide/database/connecting.html

In case you don't know in advance how many elements you will have to handle it might be a better solution to use collections instead (https://en.wikipedia.org/wiki/Java_collections_framework). It would be possible also to create a new bigger 2-dimensional array, copy the old data over and insert the new items there, but the collection framework handles this for you automatically.

In this case you could use a Map of Strings to Lists of Strings:

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class MyClass {
    public static void main(String args[]) {
        Map<String, List<String>> shades = new HashMap<>();

        ArrayList<String> shadesOfGrey = new ArrayList<>();
        shadesOfGrey.add("lightgrey");
        shadesOfGrey.add("dimgray");
        shadesOfGrey.add("sgi gray 92");

        ArrayList<String> shadesOfBlue = new ArrayList<>();
        shadesOfBlue.add("dodgerblue 2");
        shadesOfBlue.add("steelblue 2");
        shadesOfBlue.add("powderblue");

        ArrayList<String> shadesOfYellow = new ArrayList<>();
        shadesOfYellow.add("yellow 1");
        shadesOfYellow.add("gold 1");
        shadesOfYellow.add("darkgoldenrod 1");

        ArrayList<String> shadesOfRed = new ArrayList<>();
        shadesOfRed.add("indianred 1");
        shadesOfRed.add("firebrick 1");
        shadesOfRed.add("maroon 1");

        shades.put("greys", shadesOfGrey);
        shades.put("blues", shadesOfBlue);
        shades.put("yellows", shadesOfYellow);
        shades.put("reds", shadesOfRed);

        System.out.println(shades.get("greys").get(0)); // prints "lightgrey"
    }
}

Just an idea:

You may get the filesize by running command "dir":

>dir thing

Then again it returns so many things.

Maybe you can get it from there if you look for it.

But I am not sure.

This question's bit old, but, there's a tricky scenario which also leads to this error:

In controller:

ViewBag.id = //id from querystring
List<string> = GrabDataFromDBByID(ViewBag.id).Select(a=>a.ToString());

The above code will lead to an error in this part: .Select(a=>a.ToString()) because of the below reason: You're passing a ViewBag.id to a method which in compiler, it doesn't know the type, so there might be several methods with the same name and different parameters let's say:

GrabDataFromDBByID(string)
GrabDataFromDBByID(int)
GrabDataFromDBByID(whateverType)

So to prevent this case, either explicitly cast the ViewBag or create another variable storing it.

The answer is good, but for the people that want this with range(), the form to do is:

range(end):

>>> list(range(10))
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

range(start,end):

 >>> list(range(1, 11))
[1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

range(start,end, step):

 >>> list(range(0, 30, 5))
[0, 5, 10, 15, 20, 25]

Answered my own question:

IPv6 addresses are normally written as eight groups of four hexadecimal digits, where each group is separated by a colon (:).

So that's 39 characters max.

The non-greedy ? works perfectly fine. It's just that you need to select dot matches all option in the regex engines (regexpal, the engine you used, also has this option) you are testing with. This is because, regex engines generally don't match line breaks when you use .. You need to tell them explicitly that you want to match line-breaks too with .

For example,

<img\s.*?>

works fine!

Check the results here.

Also, read about how dot behaves in various regex flavours.

Output the images in a lossless format such as PNG:

ffmpeg.exe -i 10fps.h264 -r 10 -f image2 10fps.h264_%03d.png

Edit/Update: Not quite sure why I originally gave a strange filename example (with a possibly made-up extension).

I have since found that -vsync 0 is simpler than -r 10 because it avoids needing to know the frame rate.

This is something like what I currently use:

mkdir stills
ffmpeg -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

To extract only the key frames (which are likely to be of higher quality post-edit):

ffmpeg -skip_frame nokey -i my-film.mp4 -vsync 0 -f image2 stills/my-film-%06d.png

Then use another program (where you can more precisely specify quality, subsampling and DCT method – e.g. GIMP) to convert the PNGs you want to JPEG.

It is possible to obtain slightly sharper images in JPEG format this way than is possible with -qmin 1 -q:v 1 and outputting as JPEG directly from ffmpeg.

You can use the v$sql_monitor view to find queries that are running longer than 5 seconds. This may only be available in Enterprise versions of Oracle. For example this query will identify slow running queries from my TEST_APP service:

select to_char(sql_exec_start, 'dd-Mon hh24:mi'), (elapsed_time / 1000000) run_time,
       cpu_time, sql_id, sql_text 
from   v$sql_monitor
where  service_name = 'TEST_APP'
order  by 1 desc;

Note elapsed_time is in microseconds so / 1000000 to get something more readable

This error sometimes occurs in a situation like this:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

static void init_random(uint32_t initseed=0)
{
    if (initseed==0)
    {
        struct timeval tv;
        gettimeofday(&tv, NULL);
        seed=(uint32_t) (4223517*getpid()*tv.tv_sec*tv.tv_usec);
    }
    else
        seed=initseed;
#if !defined(CYGWIN) && !defined(__INTERIX)
    //seed=42
    //SG_SPRINT("initializing random number generator with %d (seed size %d)\n", seed, RNG_SEED_SIZE)
    initstate(seed, CMath::rand_state, RNG_SEED_SIZE);
#endif
}

If the following code lines not run in the run-time:

#ifndef NAN
#include <stdlib.h>
#define NAN (strtod("NAN",NULL))
#endif

you will face with an error in your code like something as follows; because initstate is placed in the stdlib.h file and it's not included:

In file included from ../../shogun/features/SubsetStack.h:14:0, 
                 from ../../shogun/features/Features.h:21,

Use a border-radius property of 50%.

So for example:

}

Others have already given great explanations regarding why you can not (and should not!) be able to add items to an IEnumerable. I will only add that if you are looking to continue coding to an interface that represents a collection and want an add method, you should code to ICollection or IList. As an added bonanza, these interfaces implement IEnumerable.

I had the same problem as you. I had a long list of arguments, most of which were irrelevant. I didn't want to hard code them in. This is what I came up with

library(magrittr)
do_func_ignore_things <- function(data, what){
    acceptable_args <- data[names(data) %in% (formals(what) %>% names)]
    do.call(what, acceptable_args %>% as.list)
}

Using this.props.children is the idiomatic way to pass instantiated components to a react component

const Label = props => <span>{props.children}</span>
const Tab = props => <div>{props.children}</div>
const Page = () => <Tab><Label>Foo</Label></Tab>

When you pass a component as a parameter directly, you pass it uninstantiated and instantiate it by retrieving it from the props. This is an idiomatic way of passing down component classes which will then be instantiated by the components down the tree (e.g. if a component uses custom styles on a tag, but it wants to let the consumer choose whether that tag is a div or span):

const Label = props => <span>{props.children}</span>
const Button = props => {
    const Inner = props.inner; // Note: variable name _must_ start with a capital letter 
    return <button><Inner>Foo</Inner></button>
}
const Page = () => <Button inner={Label}/>

If what you want to do is to pass a children-like parameter as a prop, you can do that:

const Label = props => <span>{props.content}</span>
const Tab = props => <div>{props.content}</div>
const Page = () => <Tab content={<Label content='Foo' />} />

After all, properties in React are just regular JavaScript object properties and can hold any value - be it a string, function or a complex object.

There is also the _reindex option

From documentation:

Through the Elasticsearch reindex API, available in version 5.x and later, you can connect your new Elasticsearch Service deployment remotely to your old Elasticsearch cluster. This pulls the data from your old cluster and indexes it into your new one. Reindexing essentially rebuilds the index from scratch and it can be more resource intensive to run.

POST _reindex
{
  "source": {
    "remote": {
      "host": "https://REMOTE_ELASTICSEARCH_ENDPOINT:PORT",
      "username": "USER",
      "password": "PASSWORD"
    },
    "index": "INDEX_NAME",
    "query": {
      "match_all": {}
    }
  },
  "dest": {
    "index": "INDEX_NAME"
  }
}

For frequent uses of this command I found it easy to add the location of C:\xampp\apache\bin to the PATH. Use whatever directory you have this installed in.

Then you can run from any directory in command line:

httpd -k restart

The answer above that suggests httpd -k -restart is actually a typo. You can see the commands by running httpd /?

Attempt to provide simplified explanation:

SAP

• Firstly it is a product.
• Owner company, derives its name with the product name "SAP"
• It is a management system (i.e. referred as ERP). Which means, this is a tool used for "managing the system" (domain specific - finance etc.).

Now, that SAP has created an environment around SAP. In order to operate in SAP environment (i.e. for customisations etc.), language-abstraction was required. Here comes ABAP.

ABAP

• It is a language (high level), which is used in the SAP environment for customisations or new feature implementations.
• It is high-level, because, it is known only in SAP environment.

Therefore, any customisation on the basic version of SAP given to some customer of SAP would require ABAP usage, otherwise, just delivered SAP is good enough for usage (i.e. no ABAP required).

Now is another term HANA.

HANA

• This is an in-memory RDBMS.
• Another tool/product by SAP, you would say, and its prime focus is to facilitate "analytics".
• The way, this is designed, gives high compression (column-wise storage) and hence is majorly used for "READ" operations, which is why it is associated with "analysis".

SAP and HANA together abstracts the underlying complexity of database-access queries and UI (developed in java), together, to make the user experience good for the management system (used majorly in analytics, and so that the main focus stays in analytics). This very specific tool/product, is said as "technology", as it has an environment of its own (terminologies etc.). ABAP facilitates further development of the SAP-ERP.

The underlying development is in C, C++ (and ABAP) for SAP.

If non-numeric value encountered in your code try below one. The below code is converted to float.

$PlannedAmount = ''; // empty string ''

if(!is_numeric($PlannedAmount)) {
           $PlannedAmount = floatval($PlannedAmount);
 }

 echo $PlannedAmount; //output = 0

Use a terminal-handling library like the curses module:

The curses module provides an interface to the curses library, the de-facto standard for portable advanced terminal handling.

Another helpful answer. How do I use getConstructor(params).newInstance(args)?

return Class.forName(**complete classname**)
    .getConstructor(**here pass parameters passed in constructor**)
    .newInstance(**here pass arguments**);

In my case, my class's constructor takes Webdriver as parameter, so used below code:

return Class.forName("com.page.BillablePage")
    .getConstructor(WebDriver.class)
    .newInstance(this.driver);

In the terminal type:

ip addr show

You need to either provide the absolute path to data.csv, or run your script in the same directory as data.csv.

The debate between cssSelector vs XPath would remain as one of the most subjective debate in the Selenium Community. What we already know so far can be summarized as:

• People in favor of cssSelector say that it is more readable and faster (especially when running against Internet Explorer).
• While those in favor of XPath tout it's ability to transverse the page (while cssSelector cannot).
• Traversing the DOM in older browsers like IE8 does not work with cssSelector but is fine with XPath.
• XPath can walk up the DOM (e.g. from child to parent), whereas cssSelector can only traverse down the DOM (e.g. from parent to child)
• However not being able to traverse the DOM with cssSelector in older browsers isn't necessarily a bad thing as it is more of an indicator that your page has poor design and could benefit from some helpful markup.
• Ben Burton mentions you should use cssSelector because that's how applications are built. This makes the tests easier to write, talk about, and have others help maintain.
• Adam Goucher says to adopt a more hybrid approach -- focusing first on IDs, then cssSelector, and leveraging XPath only when you need it (e.g. walking up the DOM) and that XPath will always be more powerful for advanced locators.

Dave Haeffner carried out a test on a page with two HTML data tables, one table is written without helpful attributes (ID and Class), and the other with them. I have analyzed the test procedure and the outcome of this experiment in details in the discussion Why should I ever use cssSelector selectors as opposed to XPath for automated testing?. While this experiment demonstrated that each Locator Strategy is reasonably equivalent across browsers, it didn't adequately paint the whole picture for us. Dave Haeffner in the other discussion Css Vs. X Path, Under a Microscope mentioned, in an an end-to-end test there were a lot of other variables at play Sauce startup, Browser start up, and latency to and from the application under test. The unfortunate takeaway from that experiment could be that one driver may be faster than the other (e.g. IE vs Firefox), when in fact, that's wasn't the case at all. To get a real taste of what the performance difference is between cssSelector and XPath, we needed to dig deeper. We did that by running everything from a local machine while using a performance benchmarking utility. We also focused on a specific Selenium action rather than the entire test run, and run things numerous times. I have analyzed the specific test procedure and the outcome of this experiment in details in the discussion cssSelector vs XPath for selenium. But the tests were still missing one aspect i.e. more browser coverage (e.g., Internet Explorer 9 and 10) and testing against a larger and deeper page.

Dave Haeffner in another discussion Css Vs. X Path, Under a Microscope (Part 2) mentions, in order to make sure the required benchmarks are covered in the best possible way we need to consider an example that demonstrates a large and deep page.

Test SetUp

To demonstrate this detailed example, a Windows XP virtual machine was setup and Ruby (1.9.3) was installed. All the available browsers and their equivalent browser drivers for Selenium was also installed. For benchmarking, Ruby's standard lib benchmark was used.

Test Code

require_relative 'base'
require 'benchmark'

Results

NOTE: The output is in seconds, and the results are for the total run time of 100 executions.

In Table Form:

In Chart Form:

• Chrome:

• Firefox:

• Internet Explorer 8:

• Internet Explorer 9:

• Internet Explorer 10:

• Opera:

Analyzing the Results

• Chrome and Firefox are clearly tuned for faster cssSelector performance.
• Internet Explorer 8 is a grab bag of cssSelector that won't work, an out of control XPath traversal that takes ~65 seconds, and a 38 second table traversal with no cssSelector result to compare it against.
• In IE 9 and 10, XPath is faster overall. In Safari, it's a toss up, except for a couple of slower traversal runs with XPath. And across almost all browsers, the nested sibling traversal and table cell traversal done with XPath are an expensive operation.
• These shouldn't be that surprising since the locators are brittle and inefficient and we need to avoid them.

Summary

• Overall there are two circumstances where XPath is markedly slower than cssSelector. But they are easily avoidable.
• The performance difference is slightly in favor of css-selectors for non-IE browsers and slightly in favor of xpath for IE browsers.

Trivia

You can perform the bench-marking on your own, using this library where Dave Haeffner wrapped up all the code.

The correct way to do this is:

typedef void (*callback_function)(void); // type for conciseness

callback_function disconnectFunc; // variable to store function pointer type

void D::setDisconnectFunc(callback_function pFunc)
{
    disconnectFunc = pFunc; // store
}

void D::disconnected()
{
    disconnectFunc(); // call
    connected = false;
}

Another solution is by using .animate() and appropriate CSS.

e.g.

   $('#mydiv').animate({ marginLeft: "100%"} , 4000);

JS Fiddle

This is an old question, but answering for gathering knowledge. We have an original form with a button to show the new form.

The code for the button click is below

private void button1_Click(object sender, EventArgs e)
{
    New_Form new_Form = new New_Form();
    new_Form.Show();
}

Now when click is made, New Form is shown. Since, you want to hide after 2 seconds we are adding a onload event to the new form designer

this.Load += new System.EventHandler(this.OnPageLoad);

This OnPageLoad function runs when that form is loaded

In NewForm.cs ,

public partial class New_Form : Form
{
    private Timer formClosingTimer;

    private void OnPageLoad(object sender, EventArgs e)
    {
        formClosingTimer = new Timer();  // Creating a new timer 
        formClosingTimer.Tick += new EventHandler(CloseForm); // Defining tick event to invoke after a time period
        formClosingTimer.Interval = 2000; // Time Interval in miliseconds
        formClosingTimer.Start(); // Starting a timer
    }
    private void CloseForm(object sender, EventArgs e)
    {
        formClosingTimer.Stop(); // Stoping timer. If we dont stop, function will be triggered in regular intervals
        this.Close(); // Closing the current form
    }
}

In this new form , a timer is used to invoke a method which closes that form.

Here is the new form which automatically closes after 2 seconds, we will be able operate on both the forms where no interference between those two forms.

For your knowledge,

form.close() will free the memory and we can never interact with that form again form.hide() will just hide the form, where the code part can still run

GITHUB: https://github.com/sevensc/typescript-string-operations

I implemented a class for String. Its not perfect but it works for me.

use it i.e. like this:

var getFullName = function(salutation, lastname, firstname) {
    return String.Format('{0} {1:U} {2:L}', salutation, lastname, firstname)
}

export class String {
    public static Empty: string = "";

    public static isNullOrWhiteSpace(value: string): boolean {
        try {
            if (value == null || value == 'undefined')
                return false;

            return value.replace(/\s/g, '').length < 1;
        }
        catch (e) {
            return false;
        }
    }

    public static Format(value, ...args): string {
        try {
            return value.replace(/{(\d+(:.*)?)}/g, function (match, i) {
                var s = match.split(':');
                if (s.length > 1) {
                    i = i[0];
                    match = s[1].replace('}', '');
                }

                var arg = String.formatPattern(match, args[i]);
                return typeof arg != 'undefined' && arg != null ? arg : String.Empty;
            });
        }
        catch (e) {
            return String.Empty;
        }
    }

    private static formatPattern(match, arg): string {
        switch (match) {
            case 'L':
                arg = arg.toLowerCase();
                break;
            case 'U':
                arg = arg.toUpperCase();
                break;
            default:
                break;
        }

        return arg;
    }
}

EDIT:

I extended the class and created a repository on github. It would be great if you can help to improve it!

https://github.com/sevensc/typescript-string-operations

or download the npm package

To reduce verbosity, you can use a static import:

import static java.util.concurrent.TimeUnit.NANOSECONDS;

-and henceforth just type

NANOSECONDS.toSeconds(elapsedTime);

C++11:

std::map< std::string, std::map<std::string, std::string> > m;
m["name1"]["value1"] = "data1";
m["name1"]["value2"] = "data2";
m["name2"]["value1"] = "data1";
m["name2"]["value2"] = "data2";
m["name3"]["value1"] = "data1";
m["name3"]["value2"] = "data2";

for (auto i : m)
    for (auto j : i.second)
        cout << i.first.c_str() << ":" << j.first.c_str() << ":" << j.second.c_str() << endl;

output:

name1:value1:data1
name1:value2:data2
name2:value1:data1
name2:value2:data2
name3:value1:data1
name3:value2:data2

you can try

"str".charCodeAt(0)

You can increase body size in nginx configuration file as

sudo nano /etc/nginx/nginx.conf

client_max_body_size 100M;

Restart nginx to apply the changes.

sudo service nginx restart

You can use join() to wait for all threads to finish. Keep all objects of threads in the global ArrayList at the time of creating threads. After that keep it in loop like below:

for (int i = 0; i < 10; i++) 
{
    Thread T1 = new Thread(new ThreadTest(i));                
    T1.start();                
    arrThreads.add(T1);
} 

for (int i = 0; i < arrThreads.size(); i++) 
{
    arrThreads.get(i).join(); 
}

Check here for complete details: http://www.letmeknows.com/2017/04/24/wait-for-threads-to-finish-java

Another way to continue with the example @nfreeze used is this validation method:

UserModel.schema.path('name').validate(function (value, res) {
    UserModel.findOne({name: value}, 'id', function(err, user) {
        if (err) return res(err);
        if (user) return res(false);
        res(true);
    });
}, 'already exists');

First you can use a Paginator. This is as simple as:

$allUsers = User::paginate(15);

$someUsers = User::where('votes', '>', 100)->paginate(15);

The variables will contain an instance of Paginator class. all of your data will be stored under data key.

Or you can do something like:

Old versions Laravel.

Model::all()->take(10)->get();

Newer version Laravel.

Model::all()->take(10);

just a wild guess, how about adding to index.html the following:

type="javascript"

like this:

<script type="javascript" src="public/bundle.js"> </script>

For me it worked! :-)

With EasyGui:

import easygui
print(easygui.fileopenbox())

To install:

pip install easygui

Demo:

import easygui
easygui.egdemo()

You must realize what options Jackson has available for deserialization. In Java, method argument names are not present in the compiled code. That's why Jackson can't generally use constructors to create a well-defined object with everything already set.

So, if there is an empty constructor and there are also setters, it uses the empty constructor and setters. If there are no setters, some dark magic (reflections) is used to do it.

If you want to use a constructor with Jackson, you must use the annotations as mentioned by @PiersyP in his answer. You can also use a builder pattern. If you encounter some exceptions, good luck. Error handling in Jackson sucks big time, it's hard to understand that gibberish in error messages.

An alternative that may fit in some situations is to assign the result of a command to a variable:

$ DUMMY=$( grep root /etc/passwd 2>&1 )
$ echo $?
0
$ DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
1

Since Bash and other POSIX commandline interpreters does not consider variable assignments as a command, the present command's return code is respected.

Note: assignement with the typeset or declare keyword is considered as a command, so the evaluated return code in case is the assignement itself and not the command executed in the sub-shell:

$ declare DUMMY=$( grep r00t /etc/passwd 2>&1 )
$ echo $?
0

you could register an interval on the page using setInterval, ie:

setInterval(function(){ 
    //code goes here that will be run every 5 seconds.    
}, 5000);

I'm just starting to use EC2 myself so not an expert, but Amazon's own documentation says:

we recommend that you use the local instance store for temporary data and, for data requiring a higher level of durability, we recommend using Amazon EBS volumes or backing up the data to Amazon S3.

Emphasis mine.

I do more data analysis than web hosting, so persistence doesn't matter as much to me as it might for a web site. Given the distinction made by Amazon itself, I wouldn't assume that EBS is right for everyone.

I'll try to remember to weigh in again after I've used both.

The difference between joins and include is that using the include statement generates a much larger SQL query loading into memory all the attributes from the other table(s).

For example, if you have a table full of comments and you use a :joins => users to pull in all the user information for sorting purposes, etc it will work fine and take less time than :include, but say you want to display the comment along with the users name, email, etc. To get the information using :joins, it will have to make separate SQL queries for each user it fetches, whereas if you used :include this information is ready for use.

Great example:

http://railscasts.com/episodes/181-include-vs-joins

In C# it also works with a null as the 4th parameter.

@Html.ActionLink( "Front Page", "Index", "Home", null, new { @class = "MenuButtons" })

In below Order

1. FROM & JOIN
2. WHERE
3. GROUP BY
4. HAVING
5. SELECT
6. ORDER BY
7. LIMIT

android studio 4.1.1

applicationVariants.all { variant ->
  variant.outputs.all { output ->
    def reversion = "118"
    def date = new java.text.SimpleDateFormat("yyyyMMdd").format(new Date())
    def versionName = defaultConfig.versionName
    outputFileName = "MyApp_${versionName}_${date}_${reversion}.apk"
  }
}

This can happen because java script allows white spaces sometimes if a string is concatenated with a number. try removing the spaces and create a string and then pass it into getElementById.

example:

var str = 'horseThumb_'+id;

str = str.replace(/^\s+|\s+$/g,"");

function AddBorder(id){

    document.getElementById(str).className='hand positionLeft'

}

You can't directly return a file for download via an AJAX call so, an alternative approach is to to use an AJAX call to post the related data to your server. You can then use server side code to create the Excel File (I would recommend using EPPlus or NPOI for this although it sounds as if you have this part working).

UPDATE September 2016

My original answer (below) was over 3 years old, so I thought I would update as I no longer create files on the server when downloading files via AJAX however, I have left the original answer as it may be of some use still depending on your specific requirements.

A common scenario in my MVC applications is reporting via a web page that has some user configured report parameters (Date Ranges, Filters etc.). When the user has specified the parameters they post them to the server, the report is generated (say for example an Excel file as output) and then I store the resulting file as a byte array in the TempData bucket with a unique reference. This reference is passed back as a Json Result to my AJAX function that subsequently redirects to separate controller action to extract the data from TempData and download to the end users browser.

To give this more detail, assuming you have a MVC View that has a form bound to a Model class, lets call the Model ReportVM.

First, a controller action is required to receive the posted model, an example would be:

public ActionResult PostReportPartial(ReportVM model){

   // Validate the Model is correct and contains valid data
   // Generate your report output based on the model parameters
   // This can be an Excel, PDF, Word file - whatever you need.

   // As an example lets assume we've generated an EPPlus ExcelPackage

   ExcelPackage workbook = new ExcelPackage();
   // Do something to populate your workbook

   // Generate a new unique identifier against which the file can be stored
   string handle = Guid.NewGuid().ToString();

   using(MemoryStream memoryStream = new MemoryStream()){
        workbook.SaveAs(memoryStream);
        memoryStream.Position = 0;
        TempData[handle] = memoryStream.ToArray();
   }      

   // Note we are returning a filename as well as the handle
   return new JsonResult() { 
         Data = new { FileGuid = handle, FileName = "TestReportOutput.xlsx" }
   };

}

The AJAX call that posts my MVC form to the above controller and receives the response looks like this:

$ajax({
    cache: false,
    url: '/Report/PostReportPartial',
    data: _form.serialize(), 
    success: function (data){
         var response = JSON.parse(data);
         window.location = '/Report/Download?fileGuid=' + response.FileGuid 
                           + '&filename=' + response.FileName;
    }
})

The controller action to handle the downloading of the file:

[HttpGet]
public virtual ActionResult Download(string fileGuid, string fileName)
{   
   if(TempData[fileGuid] != null){
        byte[] data = TempData[fileGuid] as byte[];
        return File(data, "application/vnd.ms-excel", fileName);
   }   
   else{
        // Problem - Log the error, generate a blank file,
        //           redirect to another controller action - whatever fits with your application
        return new EmptyResult();
   }
}

One other change that could easily be accommodated if required is to pass the MIME Type of the file as a third parameter so that the one Controller action could correctly serve a variety of output file formats.

This removes any need for any physical files to created and stored on the server, so no housekeeping routines required and once again this is seamless to the end user.

Note, the advantage of using TempData rather than Session is that once TempData is read the data is cleared so it will be more efficient in terms of memory usage if you have a high volume of file requests. See TempData Best Practice.

ORIGINAL Answer

You can't directly return a file for download via an AJAX call so, an alternative approach is to to use an AJAX call to post the related data to your server. You can then use server side code to create the Excel File (I would recommend using EPPlus or NPOI for this although it sounds as if you have this part working).

Once the file has been created on the server pass back the path to the file (or just the filename) as the return value to your AJAX call and then set the JavaScript window.location to this URL which will prompt the browser to download the file.

From the end users perspective, the file download operation is seamless as they never leave the page on which the request originates.

Below is a simple contrived example of an ajax call to achieve this:

$.ajax({
    type: 'POST',
    url: '/Reports/ExportMyData', 
    data: '{ "dataprop1": "test", "dataprop2" : "test2" }',
    contentType: 'application/json; charset=utf-8',
    dataType: 'json',
    success: function (returnValue) {
        window.location = '/Reports/Download?file=' + returnValue;
    }
});

• url parameter is the Controller/Action method where your code will create the Excel file.
• data parameter contains the json data that would be extracted from the form.
• returnValue would be the file name of your newly created Excel file.
• The window.location command redirects to the Controller/Action method that actually returns your file for download.

A sample controller method for the Download action would be:

[HttpGet]
public virtual ActionResult Download(string file)
{   
  string fullPath = Path.Combine(Server.MapPath("~/MyFiles"), file);
  return File(fullPath, "application/vnd.ms-excel", file);
}

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

Do you just mean spaces or all whitespace?

For just spaces, use str_replace:

$string = str_replace(' ', '', $string);

For all whitespace (including tabs and line ends), use preg_replace:

$string = preg_replace('/\s+/', '', $string);

(From here).

You can use a TextView or your custom TextView. The latter is when the textview cannot get focus all the time.

First, you can use a TextView or a custom TextView as the scrolling text view in your layout .xml file like this:

<com.example.myapplication.CustomTextView
            android:id="@+id/tvScrollingMessage"
            android:text="@string/scrolling_message_main_wish_list"
            android:singleLine="true"
            android:ellipsize="marquee"
            android:marqueeRepeatLimit ="marquee_forever"
            android:focusable="true"
            android:focusableInTouchMode="true"
            android:scrollHorizontally="true"
            android:layout_width="match_parent"
            android:layout_height="40dp"
            android:background="@color/black"
            android:gravity="center"
            android:textColor="@color/white"
            android:textSize="15dp"
            android:freezesText="true"/>

NOTE: in the above code snippet com.example.myapplication is an example package name and should be replaced by your own package name.

Then in case of using CustomTextView, you should define the CustomTextView class:

public class CustomTextView extends TextView {
        public CustomTextView(Context context) {
            super(context);
        }
        public CustomTextView(Context context, AttributeSet attrs) {
            super(context, attrs);

        }

        public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
            super(context, attrs, defStyle);

        }


        @Override
        protected void onFocusChanged(boolean focused, int direction, Rect previouslyFocusedRect) {
            if(focused)
                super.onFocusChanged(focused, direction, previouslyFocusedRect);
        }

        @Override
        public void onWindowFocusChanged(boolean focused) {
            if(focused)
                super.onWindowFocusChanged(focused);
        }


        @Override
        public boolean isFocused() {
            return true;
        }
    }

Hope it will be helpful to you. Cheers!

Just remove the .val(). Like:

if ( $('html').attr('lang') == 'fr-FR' ) {
    // do this
} else {
    // do that
}

There are two ways to do it because Angular Material is inconsistent, and this is very poorly documented. Angular material table won't update when a new row will arrive. Surprisingly it is told it is because performance issues. But it looks more like a by design issue, they can not change. It should be expected for the table to update when new row occurs. If this behavior should not be enabled by default there should be a switch to switch it off.

Anyways, we can not change Angular Material. But we can basically use a very poorly documented method to do it:

One - if you use an array directly as a source:

call table.renderRows()

where table is ViewChild of the mat-table

Second - if you use sorting and other features

table.renderRows() surprisingly won't work. Because mat-table is inconsistent here. You need to use a hack to tell the source changed. You do it with this method:

this.dataSource.data = yourDataSource;

where dataSource is MatTableDataSource wrapper used for sorting and other features.

I used the following code to also take in to account bank holidays:

public class WorkingDays
{
    public List<DateTime> GetHolidays()
    {
        var client = new WebClient();
        var json = client.DownloadString("https://www.gov.uk/bank-holidays.json");
        var js = new JavaScriptSerializer();
        var holidays = js.Deserialize <Dictionary<string, Holidays>>(json);
        return holidays["england-and-wales"].events.Select(d => d.date).ToList();
    }

    public int GetWorkingDays(DateTime from, DateTime to)
    {
        var totalDays = 0;
        var holidays = GetHolidays();
        for (var date = from.AddDays(1); date <= to; date = date.AddDays(1))
        {
            if (date.DayOfWeek != DayOfWeek.Saturday
                && date.DayOfWeek != DayOfWeek.Sunday
                && !holidays.Contains(date))
                totalDays++;
        }

        return totalDays;
    }
}

public class Holidays
{
    public string division { get; set; }
    public List<Event> events { get; set; }
}

public class Event
{
    public DateTime date { get; set; }
    public string notes { get; set; }
    public string title { get; set; }
}

And Unit Tests:

[TestClass]
public class WorkingDays
{
    [TestMethod]
    public void SameDayIsZero()
    {
        var service = new WorkingDays();

        var from = new DateTime(2013, 8, 12);

        Assert.AreEqual(0, service.GetWorkingDays(from, from));

    }

    [TestMethod]
    public void CalculateDaysInWorkingWeek()
    {
        var service = new WorkingDays();

        var from = new DateTime(2013, 8, 12);
        var to = new DateTime(2013, 8, 16);

        Assert.AreEqual(4, service.GetWorkingDays(from, to), "Mon - Fri = 4");

        Assert.AreEqual(1, service.GetWorkingDays(from, new DateTime(2013, 8, 13)), "Mon - Tues = 1");
    }

    [TestMethod]
    public void NotIncludeWeekends()
    {
        var service = new WorkingDays();

        var from = new DateTime(2013, 8, 9);
        var to = new DateTime(2013, 8, 16);

        Assert.AreEqual(5, service.GetWorkingDays(from, to), "Fri - Fri = 5");

        Assert.AreEqual(2, service.GetWorkingDays(from, new DateTime(2013, 8, 13)), "Fri - Tues = 2");
        Assert.AreEqual(1, service.GetWorkingDays(from, new DateTime(2013, 8, 12)), "Fri - Mon = 1");
    }

    [TestMethod]
    public void AccountForHolidays()
    {
        var service = new WorkingDays();

        var from = new DateTime(2013, 8, 23);

        Assert.AreEqual(0, service.GetWorkingDays(from, new DateTime(2013, 8, 26)), "Fri - Mon = 0");

        Assert.AreEqual(1, service.GetWorkingDays(from, new DateTime(2013, 8, 27)), "Fri - Tues = 1");
    }
}

Seems like last_accessed_on, is a date time, and you are converting '23-07-2014 09:37:00' to a varchar. This would not work, and give you conversion errors. Try

last_accessed_on= convert(datetime,'23-07-2014 09:37:00', 103)  

I think you can avoid the cast though, and update with '23-07-2014 09:37:00'. It should work given that the format is correct.

Your query is not going to work because in last_accessed_on (which is DateTime2 type), you are trying to pass a Varchar value.

You query would be

UPDATE  student_queues SET  Deleted=0 ,  last_accessed_by='raja', last_accessed_on=convert(datetime,'23-07-2014 09:37:00', 103)  
 WHERE std_id IN ('2144-384-11564') AND reject_details='REJECT'

This is preferred approach in most cases:

 File.open(yourfile, 'w') { |file| file.write("your text") }

When a block is passed to File.open, the File object will be automatically closed when the block terminates.

If you don't pass a block to File.open, you have to make sure that file is correctly closed and the content was written to file.

begin
  file = File.open("/tmp/some_file", "w")
  file.write("your text") 
rescue IOError => e
  #some error occur, dir not writable etc.
ensure
  file.close unless file.nil?
end

You can find it in documentation:

static VALUE rb_io_s_open(int argc, VALUE *argv, VALUE klass)
{
    VALUE io = rb_class_new_instance(argc, argv, klass);
    if (rb_block_given_p()) {
        return rb_ensure(rb_yield, io, io_close, io);
    }
    return io;
}

Try this:

<?php
$handle = fopen ("specialchars.csv","r");
echo '<table border="1"><tr><td>First name</td><td>Last name</td></tr><tr>';
while ($data = fgetcsv ($handle, 1000, ";")) {
        $data = array_map("utf8_encode", $data); //added
        $num = count ($data);
        for ($c=0; $c < $num; $c++) {
            // output data
            echo "<td>$data[$c]</td>";
        }
        echo "</tr><tr>";
}
?>

1) Ensure you're in branch where you need a copy of the file. for eg: i want sub branch file in master so you need to checkout or should be in master git checkout master

2) Now checkout specific file alone you want from sub branch into master,

git checkout sub_branch file_path/my_file.ext

here sub_branch means where you have that file followed by filename you need to copy.

Instead of set mouse=a use set mouse=r in .vimrc

I'm not 100% sure this is the only difference, but it is the main difference. It is also recommended to have bi-directional associations by the Hibernate docs:

http://docs.jboss.org/hibernate/core/3.3/reference/en/html/best-practices.html

Specifically:

Prefer bidirectional associations: Unidirectional associations are more difficult to query. In a large application, almost all associations must be navigable in both directions in queries.

I personally have a slight problem with this blanket recommendation -- it seems to me there are cases where a child doesn't have any practical reason to know about its parent (e.g., why does an order item need to know about the order it is associated with?), but I do see value in it a reasonable portion of the time as well. And since the bi-directionality doesn't really hurt anything, I don't find it too objectionable to adhere to.

SQL Server 2012 and Later

Just use Try_Convert instead:

TRY_CONVERT takes the value passed to it and tries to convert it to the specified data_type. If the cast succeeds, TRY_CONVERT returns the value as the specified data_type; if an error occurs, null is returned. However if you request a conversion that is explicitly not permitted, then TRY_CONVERT fails with an error.

Read more about Try_Convert.

SQL Server 2008 and Earlier

The traditional way of handling this is by guarding every expression with a case statement so that no matter when it is evaluated, it will not create an error, even if it logically seems that the CASE statement should not be needed. Something like this:

SELECT
   Account_Code =
      Convert(
         bigint, -- only gives up to 18 digits, so use decimal(20, 0) if you must
         CASE
         WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
         ELSE X.Account_Code
         END
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      CASE
      WHEN X.Account_Code LIKE '%[^0-9]%' THEN NULL
      ELSE X.Account_Code
      END
   ) BETWEEN 503100 AND 503205

However, I like using strategies such as this with SQL Server 2005 and up:

SELECT
   Account_Code = Convert(bigint, X.Account_Code),
   A.Descr
FROM
   dbo.Account A
   OUTER APPLY (
      SELECT A.Account_Code WHERE A.Account_Code NOT LIKE '%[^0-9]%'
   ) X
WHERE
   Convert(bigint, X.Account_Code) BETWEEN 503100 AND 503205

What this does is strategically switch the Account_Code values to NULL inside of the X table when they are not numeric. I initially used CROSS APPLY but as Mikael Eriksson so aptly pointed out, this resulted in the same error because the query parser ran into the exact same problem of optimizing away my attempt to force the expression order (predicate pushdown defeated it). By switching to OUTER APPLY it changed the actual meaning of the operation so that X.Account_Code could contain NULL values within the outer query, thus requiring proper evaluation order.

You may be interested to read Erland Sommarskog's Microsoft Connect request about this evaluation order issue. He in fact calls it a bug.

There are additional issues here but I can't address them now.

P.S. I had a brainstorm today. An alternate to the "traditional way" that I suggested is a SELECT expression with an outer reference, which also works in SQL Server 2000. (I've noticed that since learning CROSS/OUTER APPLY I've improved my query capability with older SQL Server versions, too--as I am getting more versatile with the "outer reference" capabilities of SELECT, ON, and WHERE clauses!)

SELECT
   Account_Code =
      Convert(
         bigint,
         (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
      ),
   A.Descr
FROM dbo.Account A
WHERE
   Convert(
      bigint,
      (SELECT A.AccountCode WHERE A.Account_Code NOT LIKE '%[^0-9]%')
   ) BETWEEN 503100 AND 503205

It's a lot shorter than the CASE statement.

you can use if() in place of decode() in mySql as follows This query will print all even id row.

mysql> select id, name from employee where id in
-> (select if(id%2=0,id,null) from employee);

A simple way to do it without the use of such a complicated draw statement:

    //Make a backup so that we can reset our graphics object after using it.
    AffineTransform backup = g2d.getTransform();
    //rx is the x coordinate for rotation, ry is the y coordinate for rotation, and angle
    //is the angle to rotate the image. If you want to rotate around the center of an image,
    //use the image's center x and y coordinates for rx and ry.
    AffineTransform a = AffineTransform.getRotateInstance(angle, rx, ry);
    //Set our Graphics2D object to the transform
    g2d.setTransform(a);
    //Draw our image like normal
    g2d.drawImage(image, x, y, null);
    //Reset our graphics object so we can draw with it again.
    g2d.setTransform(backup);

At the moment I'm selecting like this:

$('a[data-attribute=true]')

Which seems to work just fine, but it would be nice if jQuery was able to select by that attribute without the 'data-' prefix.

I haven't tested this with data added to elements via jQuery dynamically, so that could be the downfall of this method.

I know I'm late, but this is my version:

Following solution worked for me. When connecting to the db, specify that data should be truncated if they are too long (jdbcCompliantTruncation). My link looks like this:

jdbc:mysql://SERVER:PORT_NO/SCHEMA?sessionVariables=sql_mode='NO_ENGINE_SUBSTITUTION'&jdbcCompliantTruncation=false

If you increase the size of the strings, you may face the same problem in future if the string you are attempting to store into the DB is longer than the new size.

EDIT: STRICT_TRANS_TABLES has to be removed from sql_mode as well.

Although this question is related to string conversion, I stumbled upon this while wanting an easy way to write arrays to my log files. If you just want the info, and don't care about the exact cleanliness of a string you might consider:

json_encode($array)

NumPy is not just more efficient; it is also more convenient. You get a lot of vector and matrix operations for free, which sometimes allow one to avoid unnecessary work. And they are also efficiently implemented.

For example, you could read your cube directly from a file into an array:

x = numpy.fromfile(file=open("data"), dtype=float).reshape((100, 100, 100))

Sum along the second dimension:

s = x.sum(axis=1)

Find which cells are above a threshold:

(x > 0.5).nonzero()

Remove every even-indexed slice along the third dimension:

x[:, :, ::2]

Also, many useful libraries work with NumPy arrays. For example, statistical analysis and visualization libraries.

Even if you don't have performance problems, learning NumPy is worth the effort.

In my experience you can rely on dkpg's exit codes.

The return code of dpkg -s is 0 if the package is installed and 1 if it's not, so the simplest solution I found was:

dpkg -s <pkg-name> 2>/dev/null >/dev/null || sudo apt-get -y install <pkg-name>

Works fine for me...

For angular 4 I have used

<img [src]="data.pic ? data.pic : 'assets/images/no-image.png' " alt="Image" title="Image">

It works for me , I hope it may use to other's also for Angular 4-5. :)

Assuming you're on Windows (if so you should tag your question as such!), on this MSDN page you can find the source for a simple, useful HRTimer C++ class that wraps the needed system calls to do something very close to what you require (it would be easy to add a GetTicks() method to it, in particular, to do exactly what you require).

On non-Windows platforms, there's no QueryPerformanceCounter function, so the solution won't be directly portable. However, if you do wrap it in a class such as the above-mentioned HRTimer, it will be easier to change the class's implementation to use what the current platform is indeed able to offer (maybe via Boost or whatever!).

Try invoking your command with Invoke-Expression:

Invoke-Expression $cmd1

Here is a working example on my machine:

$cmd = "& 'C:\Program Files\7-zip\7z.exe' a -tzip c:\temp\test.zip c:\temp\test.txt"
Invoke-Expression $cmd

iex is an alias for Invoke-Expression so you could do:

iex $cmd1

It's browser dependent. "By default, Internet Explorer has a KeepAliveTimeout value of one minute and an additional limiting factor (ServerInfoTimeout) of two minutes. Either setting can cause Internet Explorer to reset the socket." - from IE support http://support.microsoft.com/kb/813827

Firefox is around the same value I think as well.

Usually though server timeout are set lower than browser timeouts, but at least you can control that and set it higher.

You'd rather handle the timeout though, so that way you can act upon such an event. See this thread: How to detect timeout on an AJAX (XmlHttpRequest) call in the browser?

            WHERE  EE.STUDENTNUMBER=E.STUDENTNUMBER
            ORDER BY sortOrder

FROM EDUCATION E
GROUP BY E.STUDENTNUMBER

var id = mongoose.Types.ObjectId('4edd40c86762e0fb12000003');

While the above mentioned methods do work, but each one has it's own kind of problems.

You can use getline() or getdelim(), if you are using posix supported platform. If you are using windows and minigw as your compiler, then it should be available.

getline() is defined as :

ssize_t getline(char **lineptr, size_t *n, FILE *stream);

In order to take input, first you need to create a pointer to char type.

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

// s is a pointer to char type.
char *s;
// size is of size_t type, this number varies based on your guess of 
// how long the input is, even if the number is small, it isn't going 
// to be a problem
size_t size = 10;

int main(){
// allocate s with the necessary memory needed, +1 is added 
// as its input also contains, /n character at the end.
    s = (char *)malloc(size+1);
    getline(&s,&size,stdin);
    printf("%s",s);
    return 0;
}

Sample Input:Hello world to the world!

Output:Hello world to the world!\n

One thing to notice here is, even though allocated memory for s is 11 bytes, where as input size is 26 bytes, getline reallocates s using realloc().

So it doesn't matter how long your input is.

size is updated with no.of bytes read, as per above sample input size will be 27.

getline() also considers \n as input.So your 's' will hold '\n' at the end.

There is also more generic version of getline(), which is getdelim(), which takes one more extra argument, that is delimiter.

getdelim() is defined as:

ssize_t getdelim(char **lineptr, size_t *n, int delim, FILE *stream);

double.toString() should work. Not the variable type Double, but the variable itself double.

Simply You can use following methods.

using (WebClient client = new WebClient()) 
{
    client.DownloadFile(new Uri(url), @"c:\temp\image35.png");
    // OR 
    client.DownloadFileAsync(new Uri(url), @"c:\temp\image35.png");
}

These methods are almost same as DownloadString(..) and DownloadStringAsync(...). They store the file in Directory rather than in C# string and no need of Format extension in URi

If You don't know the Format(.png, .jpeg etc) of Image

public void SaveImage(string filename, ImageFormat format)
{    
    WebClient client = new WebClient();
    Stream stream = client.OpenRead(imageUrl);
    Bitmap bitmap;  bitmap = new Bitmap(stream);

    if (bitmap != null)
    {
        bitmap.Save(filename, format);
    }

    stream.Flush();
    stream.Close();
    client.Dispose();
}

Using it

try
{
    SaveImage("--- Any Image Path ---", ImageFormat.Png)
}
catch(ExternalException)
{
    // Something is wrong with Format -- Maybe required Format is not 
    // applicable here
}
catch(ArgumentNullException)
{   
    // Something wrong with Stream
}

Though this is an old post, I am posting how I resolved in case it helps others. Since I used sudo to do the install of the boto3 library the permissions on the boto3 directory was set to 700. Either change the permissions to be readable by others or run the python command as sudo.

var fruits = ["apple","pear","peach"];
for (fruit of fruits) {
    console.log(fruits.indexOf(fruit));
    //it shows the index of every fruit from fruits
}

the for loop traverses the array, while the indexof property takes the value of the index that matches the array. P.D this method has some flaws with numbers, so use fruits

There are a lot of good answers here, but I only want to add one thing. It sometimes happens that you want to scroll your ScrollView to a specific view of the layout, instead of a full scroll to the top or the bottom.

A simple example: in a registration form, if the user tap the "Signup" button when a edit text of the form is not filled, you want to scroll to that specific edit text to tell the user that he must fill that field.

In that case, you can do something like that:

scrollView.post(new Runnable() { 
        public void run() { 
             scrollView.scrollTo(0, editText.getBottom());
        } 
});

or, if you want a smooth scroll instead of an instant scroll:

scrollView.post(new Runnable() { 
            public void run() { 
                 scrollView.smoothScrollTo(0, editText.getBottom());
            } 
    });

Obviously you can use any type of view instead of Edit Text. Note that getBottom() returns the coordinates of the view based on its parent layout, so all the views used inside the ScrollView should have only a parent (for example a Linear Layout).

If you have multiple parents inside the child of the ScrollView, the only solution i've found is to call requestChildFocus on the parent view:

editText.getParent().requestChildFocus(editText, editText);

but in this case you cannot have a smooth scroll.

I hope this answer can help someone with the same problem.

I was finally able to resolve the "Excel connection issue" in my case it was not a 64 bit issue like some of them had encounterd, I noticed the package worked fine when i didnt enable the package configuration, but i wanted my package to run with the configuration file, digging further into it i noticed i had selected all the properties that were available, I unchecked all and checked only the ones that I needed to store in the package configuration file. and ta dha it works :)

Basically

• extern linkage variable is visible in all files
• internal linkage variable is visible in single file.

Explain: const variables internally link by default unless otherwise declared as extern

1. by default, global variable is external linkage
2. but, const global variable is internal linkage
3. extra, extern const global variable is external linkage

A pretty good material about linkage in C++

Add your C:\WinPython-64bit-3.4.4.1\python_***\Scripts folder to your system PATH variable by doing the following:

1. Select Start, select Control Panel. double click System, and select the Advanced tab.

2. Click Environment Variables. ...

3. In the Edit System Variable (or New System Variable) window, specify the value of the PATH environment variable. ...

4. Reopen Command prompt window

As per the documentation, these are just synonyms. size() is there to be consistent with other STL containers (like vector, map, etc.) and length() is to be consistent with most peoples' intuitive notion of character strings. People usually talk about a word, sentence or paragraph's length, not its size, so length() is there to make things more readable.

>>> import math
>>> import numpy as np
>>> import scipy
>>> math.pi == np.pi == scipy.pi
True

So it doesn't matter, they are all the same value.

The only reason all three modules provide a pi value is so if you are using just one of the three modules, you can conveniently have access to pi without having to import another module. They're not providing different values for pi.

From LDAP, there is not a query method to determine an empty string.

The best practice would be to scrub your data inputs to LDAP as an empty or null value in LDAP is no value at all.

To determine this you would need to query for all with a value (manager=*) and then use code to determine the ones that were a "space" or null value.

And as Terry said, storing an empty or null value in an attribute of DN syntax is wrong.

Some LDAP server implementations will not permit entering a DN where the DN entry does not exist.

Perhaps, you could, if your DN's are consistent, use something like:

(&(!(manager=cn*))(manager=*))

This should return any value of manager where there was a value for manager and it did not start with "cn".

However, some LDAP implementations will not allow sub-string searches on DN syntax attributes.

SELECT COUNT(DISTINCT productId) from  table_name WHERE keyword='$keyword'

I will simply leave this here because none of the other approaches worked for me. Also, I can look it up myself when I need it for new devices.

THIS IS THE WAY IT WORKS:

1. Install Anaconda
2. Open Anaconda Prompt
3. conda create --name tensorflow
4. conda activate tensorflow
5. Search with conda search tensorflow for all available TensorFlow versions
6. Choose the one you need (usually the newest one)
7. Explicitly name the version now (otherwise it happened to me that version 1.14 was installed): conda install -c conda-forge tensorflow=YOUR_VERSION
8. Open Anaconda, choose the new environment and install Spyder
9. Install Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019
10. Download msvcp140.dll and add the .dll-File to the Windows\System32 folder

Now it should work like a charm!

TROUBLESHOOTING:

If it still doesn't work, try this, it worked for me:

Open Anaconda-Prompt:

1. Create an environment with Python 3.6 like this: conda create --name tensorflow_env python=3.6
2. conda activate tensorflow
3. Steps 6. and 6. from the list above
4. conda install tensorflow=YOUR_VERSION(not forge, just like this!)
5. Now do steps 8, 9, 10 from above

TENSORFLOW GPU:

If you want to use your GPU, do it the same way as described above, with the only difference to install tensorflow-gpu instead if tensorflow.

And, you must install the newest NVIDIA driver for your GPU, you can find and choose the right one here.

(Yes, in TF 2 there's both, a CPU and GPU support, in the "normal" library. However, if you install tensorflow-gpu via conda, it installs the CUDA and cudNN etc. you need automatically for you - also the right versions. This way easier and faster.)

It's a pity that both of the answers analyze the problem but didn't give a direct answer. Let's see the code.

Z = np.array([1.0, 1.0, 1.0, 1.0])  

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B
Nlayers = Z.size
N = 3
TempLake = np.zeros((N+1, Nlayers))
kOUT = np.zeros(N + 1)

for i in xrange(N):
    # store the i-th result of
    # function "func" in i-th item in kOUT
    kOUT[i] = func(TempLake[i], Z)

The error shows that you set the ith item of kOUT(dtype:int) into an array. Here every item in kOUT is an int, can't directly assign to another datatype. Hence you should declare the data type of kOUT when you create it. For example, like:

Change the statement below:

kOUT = np.zeros(N + 1)

into:

kOUT = np.zeros(N + 1, dtype=object)

or:

kOUT = np.zeros((N + 1, N + 1))

All code:

import numpy as np
Z = np.array([1.0, 1.0, 1.0, 1.0])

def func(TempLake, Z):
    A = TempLake
    B = Z
    return A * B

Nlayers = Z.size
N = 3
TempLake = np.zeros((N + 1, Nlayers))

kOUT = np.zeros(N + 1, dtype=object)
for i in xrange(N):
    kOUT[i] = func(TempLake[i], Z)

Hope it can help you.

First off you can't have just a number for your id unless you are using the HTML5 DOCTYPE. Secondly, you need to either remove the # in each id or replace it with this:

$container.cycle(id.replace('#','')); 

This worked for me:

Import Service

import 'package:flutter/services.dart';

Then add:

@override
  Widget build(BuildContext context) {

    SystemChrome.setSystemUIOverlayStyle(SystemUiOverlayStyle(
      statusBarColor: Colors.white,
      statusBarBrightness: Brightness.dark,
    ));
    return MaterialApp(home: Scaffold(

You can use cut:

cut -c N- file.txt > new_file.txt

-c: characters

file.txt: input file

new_file.txt: output file

N-: Characters from N to end to be cut and output to the new file.

Can also have other args like: 'N' , 'N-M', '-M' meaning nth character, nth to mth character, first to mth character respectively.

This will perform the operation to each line of the input file.

I think you should check sending your messages using the fan-out exchanger. That way you willl receiving the same message for differents consumers, under the table RabbitMQ is creating differents queues for each one of this new consumers/subscribers.

You can use window.btoa and window.atob...

const encoded = window.btoa('Alireza Dezfoolian'); // encode a string
const decoded = window.atob(encoded); // decode the string

Probably using the way which MDN is can do your job the best... Also accepting unicode... using these two simple functions:

// ucs-2 string to base64 encoded ascii
function utoa(str) {
    return window.btoa(unescape(encodeURIComponent(str)));
}
// base64 encoded ascii to ucs-2 string
function atou(str) {
    return decodeURIComponent(escape(window.atob(str)));
}
// Usage:
utoa('? à la mode'); // 4pyTIMOgIGxhIG1vZGU=
atou('4pyTIMOgIGxhIG1vZGU='); // "? à la mode"

utoa('I \u2661 Unicode!'); // SSDimaEgVW5pY29kZSE=
atou('SSDimaEgVW5pY29kZSE='); // "I ? Unicode!"

Making it invisible with visibility still makes it use up space. Rather try set the display to none to make it invisible, and then set the display to block to make it visible.

Embedded environment, sometime, there is no MMU, less memory, less storage space. In C programming level, almost same, cross compiler do their job.

I had this problem and the comprehensive descriptions proposed in this helped me to fix it.

The second declared problem was my issue. I used a third-party repository which I had just added it do the repository part of the pom file in my project. I add the same repository information into pluginrepository to resolve this problem.

To return the queryset you retrieved with queryset = Users.objects.all(), you first need to serialize them.

Serialization is the process of converting one data structure to another. Using Class-Based Views, you could return JSON like this.

from django.core.serializers import serialize
from django.http import JsonResponse
from django.views.generic import View

class JSONListView(View):
    def get(self, request, *args, **kwargs):
        qs = User.objects.all()
        data = serialize("json", qs)
        return JsonResponse(data)

This will output a list of JSON. For more detail on how this works, check out my blog article How to return a JSON Response with Django. It goes into more detail on how you would go about this.

A callback is commonly used in asynchronous programming, so you could create a method which handles the response from a web service. When you call the web service, you could pass the method to it so that when the web service responds, it call's the method you told it ... it "calls back".

In Java this can commonly be done through implementing an interface and passing an object (or an anonymous inner class) that implements it. You find this often with transactions and threading - such as the Futures API.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/concurrent/Future.html

I guess your code relates to Windows Forms.
You call BeginInvoke if you need something to be executed asynchronously in the UI thread: change control's properties in most of the cases.
Roughly speaking this is accomplished be passing the delegate to some procedure which is being periodically executed. (message loop processing and the stuff like that)

If BeginInvoke is called for Delegate type the delegate is just invoked asynchronously.
(Invoke for the sync version.)

If you want more universal code which works perfectly for WPF and WinForms you can consider Task Parallel Library and running the Task with the according context. (TaskScheduler.FromCurrentSynchronizationContext())

And to add a little to already said by others: Lambdas can be treated either as anonymous methods or expressions.
And that is why you cannot just use var with lambdas: compiler needs a hint.

UPDATE:

this requires .Net v4.0 and higher

// This line must be called in UI thread to get correct scheduler
var scheduler = System.Threading.Tasks.TaskScheduler.FromCurrentSynchronizationContext();

// this can be called anywhere
var task = new System.Threading.Tasks.Task( () => someformobj.listBox1.SelectedIndex = 0);

// also can be called anywhere. Task  will be scheduled for execution.
// And *IF I'm not mistaken* can be (or even will be executed synchronously)
// if this call is made from GUI thread. (to be checked) 
task.Start(scheduler);

If you started the task from other thread and need to wait for its completition task.Wait() will block calling thread till the end of the task.

From the docs:

Use the LinkButton control to create a hyperlink-style button on the Web page. The LinkButton control has the same appearance as a HyperLink control, but has the same functionality as a Button control. If you want to link to another Web page when the control is clicked, consider using the HyperLink control.

As this isn't actually performing a link in the standard sense, there's no Target property on the control (the HyperLink control does have a Target) - it's attempting to perform a PostBack to the server from a text link.

Depending on what you are trying to do you could either:

1. Use a HyperLink control, and set the Target property
2. Provide a method to the OnClientClick property that opens a new window to the correct place.
3. In your code that handles the PostBack add some JavaScript to fire on PageLoad that will open a new window correct place.

Use the Base Context of the Activity in which your fragment resides to start an Intent.

Intent j = new Intent(fBaseCtx, NewactivityName.class);

Compile the program with:

g++ -Wall -Wextra -Werror -c main.cpp -o main.o

as cout is present in the C++ standard library, which would need explicit linking with -lstdc++ when using gcc; g++ links the standard library by default.

With gcc, (g++ should be preferred over gcc)

gcc main.cpp -lstdc++ -o main.o

we have to use string::size_type for the return type of the find function otherwise the comparison with string::npos might not work. size_type, which is defined by the allocator of the string, must be an unsigned integral type. The default allocator, allocator, uses type size_t as size_type. Because -1 is converted into an unsigned integral type, npos is the maximum unsigned value of its type. However, the exact value depends on the exact definition of type size_type. Unfortunately, these maximum values differ. In fact, (unsigned long)-1 differs from (unsigned short)-1 if the size of the types differs. Thus, the comparison

idx == std::string::npos

might yield false if idx has the value -1 and idx and string::npos have different types:

std::string s;
...
int idx = s.find("not found"); // assume it returns npos
if (idx == std::string::npos) { // ERROR: comparison might not work
...
}

One way to avoid this error is to check whether the search fails directly:

if (s.find("hi") == std::string::npos) {
...
}

However, often you need the index of the matching character position. Thus, another simple solution is to define your own signed value for npos:

const int NPOS = -1;

Now the comparison looks a bit different and even more convenient:

if (idx == NPOS) { // works almost always
...
}

After some testing with an icon with 8, 16, 20, 24, 32, 40, 48, 64, 96, 128 and 256 pixels (256 in PNG) in Windows 7:

• At 100% resolution: Explorer uses 16, 40, 48, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 125% resolution: Explorer uses 20, 40, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 150% resolution: Explorer uses 24, 48, and 256. Windows Photo Viewer uses 96. Paint uses 256.
• At 200% resolution: Explorer uses 40, 64, 96, and 256. Windows Photo Viewer uses 128. Paint uses 256.

So 8, 32 were never used (it's strange to me for 32) and 128 only by Windows Photo Viewer with a very high dpi screen, i.e. almot never used.

It means your icon should at least provide 16, 48 and 256 for Windows 7. For supporting newer screens with high resolutions, you should provide 16, 20, 24, 40, 48, 64, 96, and 256. For Windows 7, all pictures can be compressed using PNG but for backward compatibility with Windows XP, 16 to 48 should not be compressed.

Workbooks.Open does work too.

Workbooks.Open ActiveWorkbook.Path & "\Temp.csv", Local:=True

this works/is needed because i use Excel in germany and excel does use "," to separate .csv by default because i use an english installation of windows. even if you use the code below excel forces the "," separator.

Workbooks.Open ActiveWorkbook.Path & "\Test.csv", , , 6, , , , , ";"

and Workbooks.Open ActiveWorkbook.Path & "\Temp.csv", , , 4 +variants of this do not work(!)

why do they even have the delimiter parameter if it is blocked by the Local parameter ?! this makes no sense at all. but now it works.

Include the following function at the start of your code, whenever you want to busy wait. This is distinct from sleep, because the process will be utilizing 100% cpu while this function is running.

Note that the name sleep for this function is misleading, since the CPU will not be sleeping at all.

I'd use popen() (++waqas).

But sometimes you need reading and writing...

It seems like nobody does things the hard way any more.

(Assuming a Unix/Linux/Mac environment, or perhaps Windows with a POSIX compatibility layer...)

You also might want to play around with select() and non-blocking reads.

fd_set          readfds;
struct timeval  timeout;

timeout.tv_sec  = 0;    /* Seconds */
timeout.tv_usec = 1000; /* Microseconds */

FD_ZERO(&readfds);
FD_SET(childToParent[READ_FD], &readfds);

switch (select (1 + childToParent[READ_FD], &readfds, (fd_set*)NULL, (fd_set*)NULL, & timeout))
{
  case 0: /* Timeout expired */
    break;

  case -1:
    if ((errno == EINTR) || (errno == EAGAIN))
    {
      errno = 0;
      break;
    }
    else
    {
      FAIL("Select() Failed");
      exit(-1);
    }

  case 1:  /* We have input */
    readResult = read(childToParent[READ_FD], buffer, BUFFER_SIZE);
    // However you want to handle it...
    break;

  default:
    FAIL("How did we see input on more than one file descriptor?");
    exit(-1);
}

A bit late, but maybe someone finds it useful.

For me, ISNULL was out of question due to the table scan. UNION ALL would need me to repeat a complex query, and due to me selecting only the TOP X it would not have been very efficient.

If you are able to change the table design, you can:

1. Add another field, just for sorting, such as Next_Contact_Date_Sort.

2. Create a trigger that fills that field with a large (or small) value, depending on what you need:

   CREATE TRIGGER FILL_SORTABLE_DATE ON YOUR_TABLE AFTER INSERT,UPDATE AS 
   BEGIN
       SET NOCOUNT ON;
       IF (update(Next_Contact_Date)) BEGIN
       UPDATE YOUR_TABLE SET Next_Contact_Date_Sort=IIF(YOUR_TABLE.Next_Contact_Date IS NULL, 99/99/9999, YOUR_TABLE.Next_Contact_Date_Sort) FROM inserted i WHERE YOUR_TABLE.key1=i.key1 AND YOUR_TABLE.key2=i.key2
       END
   END
   

In bash:

$ convert -version

or

$ /usr/local/bin/convert -version

No need to write any PHP file just to check.

This sometimes can be thrown before the actual log4j2 configuration file found on the web servlet. at least for my case I think so. Cuz I already have in my web.xml

  <context-param>
    <param-name>log4jConfiguration</param-name>
    <param-value>classpath:log4j2-app.xml</param-value>
  </context-param>

and checking the log4j-web source; in class

org.apache.logging.log4j.web.Log4jWebInitializerImpl

there is the line;

String location = this.substitutor
                 .replace(this.servletContext.getInitParameter("log4jConfiguration"));

all those makes me think that this is temporary log before configuration found.

I also like to use MsgBox for debugging, and I've run into this same issue more than once. Now I always add a Cancel button to the popup, and exit the macro if Cancel is pressed. Example code:

    If MsgBox("Debug message", vbOKCancel, "Debugging") = vbCancel Then Exit Sub

you can use generic class:

class Wrapped<T>  {
    private T _value;

    public Action ValueChanged;

    public T Value
    {
        get => _value;

        set
        {
            _value = value;
            OnValueChanged();
        }
    }

    protected virtual void OnValueChanged() => ValueChanged?.Invoke() ;
}

and will be able to do the following:

var i = new Wrapped<int>();

i.ValueChanged += () => { Console.WriteLine("changed!"); };

i.Value = 10;
i.Value = 10;
i.Value = 10;
i.Value = 10;

Console.ReadKey();

result:

changed!
changed!
changed!
changed!
changed!
changed!
changed!

I like this "real world" code example of pointer to pointer usage, in Git 2.0, commit 7b1004b:

Linus once said:

I actually wish more people understood the really core low-level kind of coding. Not big, complex stuff like the lockless name lookup, but simply good use of pointers-to-pointers etc.
For example, I've seen too many people who delete a singly-linked list entry by keeping track of the "prev" entry, and then to delete the entry, doing something like:

   if (prev)
     prev->next = entry->next;
   else
     list_head = entry->next;

and whenever I see code like that, I just go "This person doesn't understand pointers". And it's sadly quite common.

People who understand pointers just use a "pointer to the entry pointer", and initialize that with the address of the list_head. And then as they traverse the list, they can remove the entry without using any conditionals, by just doing a

*pp =  entry->next

Applying that simplification lets us lose 7 lines from this function even while adding 2 lines of comment.

- struct combine_diff_path *p, *pprev, *ptmp;
+ struct combine_diff_path *p, **tail = &curr;

Chris points out in the comments to the 2016 video "Linus Torvalds's Double Pointer Problem".

kumar points out in the comments the blog post "Linus on Understanding Pointers", where Grisha Trubetskoy explains:

Imagine you have a linked list defined as:

   typedef struct list_entry {
       int val;
       struct list_entry *next;
   } list_entry;

You need to iterate over it from the beginning to end and remove a specific element whose value equals the value of to_remove.
The more obvious way to do this would be:

   list_entry *entry = head; /* assuming head exists and is the first entry of the list */
   list_entry *prev = NULL;
   
   while (entry) { /* line 4 */
       if (entry->val == to_remove)     /* this is the one to remove ; line 5 */
           if (prev)
              prev->next = entry->next; /* remove the entry ; line 7 */
           else
               head = entry->next;      /* special case - first entry ; line 9 */
   
       /* move on to the next entry */
       prev = entry;
       entry = entry->next;
   }

What we are doing above is:

• iterating over the list until entry is NULL, which means we’ve reached the end of the list (line 4).
• When we come across an entry we want removed (line 5),
• we assign the value of current next pointer to the previous one,
• thus eliminating the current element (line 7).

There is a special case above - at the beginning of the iteration there is no previous entry (prev is NULL), and so to remove the first entry in the list you have to modify head itself (line 9).

What Linus was saying is that the above code could be simplified by making the previous element a pointer to a pointer rather than just a pointer.
The code then looks like this:

   list_entry **pp = &head; /* pointer to a pointer */
   list_entry *entry = head;

   while (entry) {
       if (entry->val == to_remove)
           *pp = entry->next;
       else
            pp = &entry->next;
       entry = entry->next;
   }

The above code is very similar to the previous variant, but notice how we no longer need to watch for the special case of the first element of the list, since pp is not NULL at the beginning. Simple and clever.

Also, someone in that thread commented that the reason this is better is because *pp = entry->next is atomic. It is most certainly NOT atomic.
The above expression contains two dereference operators (* and ->) and one assignment, and neither of those three things is atomic.
This is a common misconception, but alas pretty much nothing in C should ever be assumed to be atomic (including the ++ and -- operators)!

Select column_name, column_name1,column_name2, count(1) as temp from table_name group by column_name having temp > 1

With a Twig extension, you can create a parameterTwig function:

{{ parameter('jira_host') }}

TwigExtension.php:

class TwigExtension extends \Twig_Extension
{
    public $container;

    public function getFunctions()
    {
        return [
            new \Twig_SimpleFunction('parameter', function($name)
            {
                return $this->container->getParameter($name);
            })
        ];
    }


    /**
     * Returns the name of the extension.
     *
     * @return string The extension name
     */
    public function getName()
    {
        return 'iz';
    }
}

service.yml:

  iz.twig.extension:
    class: IzBundle\Services\TwigExtension
    properties:
      container: "@service_container"
    tags:
      - { name: twig.extension }

Look up the new HTML5 Input Types. These instruct browsers to perform client-side filtering of data, but the implementation is incomplete across different browsers. The pattern attribute will do regex-style filtering, but, again, browsers don't fully (or at all) support it.

However, these won't block the input itself, it will simply prevent submitting the form with the invalid data. You'll still need to trap the onkeydown event to block key input before it displays on the screen.

A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point.

For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point. Without that restriction it is floating point.

Often, when fixed point is used, the programmer actually uses an integer and then makes the assumption that some of the digits are beyond the decimal point. For example, I might want to keep two digits of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.

Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the decimal place goes.

Adding the spring boot starter dependency fixed my error.

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>

This is required if you want to start the tomcat as an embeded server.
