To add up on the answer, I used this at the beginning of the needed script. So it runs smoothly on different environments.

import os
import matplotlib as mpl
if os.environ.get('DISPLAY','') == '':
    print('no display found. Using non-interactive Agg backend')
    mpl.use('Agg')
import matplotlib.pyplot as plt

Because I didn't want it to be alsways using the 'Agg' backend, only when it would go through Travis CI for example.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

You are using setTimeout wrong way. The (one of) function signature is setTimeout(callback, delay). So you can easily specify what code should be run after what delay.

var codeAddress = (function() {
    var index = 0;
    var delay = 100;

    function GeocodeCallback(results, status) {
        if (status == google.maps.GeocoderStatus.OK) {
            map.setCenter(results[0].geometry.location);
            new google.maps.Marker({ map: map, position: results[0].geometry.location, animation: google.maps.Animation.DROP });
            console.log(results);
        }
        else alert("Geocode was not successful for the following reason: " + status);
    };

    return function(vPostCode) {
        if (geocoder) setTimeout(geocoder.geocode.bind(geocoder, { 'address': "'" + vPostCode + "'"}, GeocodeCallback), index*delay);
        index++;
    };
})();

This way, every codeAddress() call will result in geocoder.geocode() being called 100ms later after previous call.

I also added animation to marker so you will have a nice animation effect with markers being added to map one after another. I'm not sure what is the current google limit, so you may need to increase the value of delay variable.

Also, if you are each time geocoding the same addresses, you should instead save the results of geocode to your db and next time just use those (so you will save some traffic and your application will be a little bit quicker)

Update: This will create a second context same as in applicationContext.xml

or you can add this code snippet to your web.xml

<servlet>
    <servlet-name>spring-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
          <param-name>contextConfigLocation</param-name>
          <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

instead of

<servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
</servlet>

I think this is very easy to do with very few lines. here is my solution

.buttonToLink{
   background: none;
   border: none;
   color: red
}

.buttonToLink:hover{
   background: none;
   text-decoration: underline;
}

<button  class="buttonToLink">A simple link button</button>

To verify whether is your pip installation problem, try using easy_install to install an earlier version of pip:

easy_install pip==9.0.1

If this succeed, pip should be working now. Then you can go ahead to install any other version of pip you want with:

pip install pip==10....

Or you can just stay with version 9.0.1, as your project requires version >= 9.0.

Try building your project again.

I have two demos, one with jQuery and one without. Neither use date functions and are about as simple as it gets.

Demo with vanilla JavaScript

function startTimer(duration, display) {_x000D_
    var timer = duration, minutes, seconds;_x000D_
    setInterval(function () {_x000D_
        minutes = parseInt(timer / 60, 10);_x000D_
        seconds = parseInt(timer % 60, 10);_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds;_x000D_
_x000D_
        if (--timer < 0) {_x000D_
            timer = duration;_x000D_
        }_x000D_
    }, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time">05:00</span> minutes!</div>_x000D_
</body>

Demo with jQuery

function startTimer(duration, display) {
    var timer = duration, minutes, seconds;
    setInterval(function () {
        minutes = parseInt(timer / 60, 10);
        seconds = parseInt(timer % 60, 10);

        minutes = minutes < 10 ? "0" + minutes : minutes;
        seconds = seconds < 10 ? "0" + seconds : seconds;

        display.text(minutes + ":" + seconds);

        if (--timer < 0) {
            timer = duration;
        }
    }, 1000);
}

jQuery(function ($) {
    var fiveMinutes = 60 * 5,
        display = $('#time');
    startTimer(fiveMinutes, display);
});

However if you want a more accurate timer that is only slightly more complicated:

function startTimer(duration, display) {_x000D_
    var start = Date.now(),_x000D_
        diff,_x000D_
        minutes,_x000D_
        seconds;_x000D_
    function timer() {_x000D_
        // get the number of seconds that have elapsed since _x000D_
        // startTimer() was called_x000D_
        diff = duration - (((Date.now() - start) / 1000) | 0);_x000D_
_x000D_
        // does the same job as parseInt truncates the float_x000D_
        minutes = (diff / 60) | 0;_x000D_
        seconds = (diff % 60) | 0;_x000D_
_x000D_
        minutes = minutes < 10 ? "0" + minutes : minutes;_x000D_
        seconds = seconds < 10 ? "0" + seconds : seconds;_x000D_
_x000D_
        display.textContent = minutes + ":" + seconds; _x000D_
_x000D_
        if (diff <= 0) {_x000D_
            // add one second so that the count down starts at the full duration_x000D_
            // example 05:00 not 04:59_x000D_
            start = Date.now() + 1000;_x000D_
        }_x000D_
    };_x000D_
    // we don't want to wait a full second before the timer starts_x000D_
    timer();_x000D_
    setInterval(timer, 1000);_x000D_
}_x000D_
_x000D_
window.onload = function () {_x000D_
    var fiveMinutes = 60 * 5,_x000D_
        display = document.querySelector('#time');_x000D_
    startTimer(fiveMinutes, display);_x000D_
};

<body>_x000D_
    <div>Registration closes in <span id="time"></span> minutes!</div>_x000D_
</body>

Now that we have made a few pretty simple timers we can start to think about re-usability and separating concerns. We can do this by asking "what should a count down timer do?"

• Should a count down timer count down? Yes
• Should a count down timer know how to display itself on the DOM? No
• Should a count down timer know to restart itself when it reaches 0? No
• Should a count down timer provide a way for a client to access how much time is left? Yes

So with these things in mind lets write a better (but still very simple) CountDownTimer

function CountDownTimer(duration, granularity) {
  this.duration = duration;
  this.granularity = granularity || 1000;
  this.tickFtns = [];
  this.running = false;
}

CountDownTimer.prototype.start = function() {
  if (this.running) {
    return;
  }
  this.running = true;
  var start = Date.now(),
      that = this,
      diff, obj;

  (function timer() {
    diff = that.duration - (((Date.now() - start) / 1000) | 0);

    if (diff > 0) {
      setTimeout(timer, that.granularity);
    } else {
      diff = 0;
      that.running = false;
    }

    obj = CountDownTimer.parse(diff);
    that.tickFtns.forEach(function(ftn) {
      ftn.call(this, obj.minutes, obj.seconds);
    }, that);
  }());
};

CountDownTimer.prototype.onTick = function(ftn) {
  if (typeof ftn === 'function') {
    this.tickFtns.push(ftn);
  }
  return this;
};

CountDownTimer.prototype.expired = function() {
  return !this.running;
};

CountDownTimer.parse = function(seconds) {
  return {
    'minutes': (seconds / 60) | 0,
    'seconds': (seconds % 60) | 0
  };
};

So why is this implementation better than the others? Here are some examples of what you can do with it. Note that all but the first example can't be achieved by the startTimer functions.

An example that displays the time in XX:XX format and restarts after reaching 00:00

An example that displays the time in two different formats

An example that has two different timers and only one restarts

An example that starts the count down timer when a button is pressed

log4j does not support this directly.

As you do not want a configuration file, you most likely use programmatic configuration. I would suggest that you look into scanning all the system properties, and explicitly program what you want based on this.

calling bean action from a will be a good idea,keep attribute autoRun="true" example below

<p:remoteCommand autoRun="true" name="myRemoteCommand" action="#{bean.action}" partialSubmit="true" update=":form" />

If repeating the same code is the issue, write an extension method on the String class that encapsulates the splitting logic.

Yes, you can. People were writing object-oriented C before C++ or Objective-C came on the scene. Both C++ and Objective-C were, in parts, attempts to take some of the OO concepts used in C and formalize them as part of the language.

Here's a really simple program that shows how you can make something that looks-like/is a method call (there are better ways to do this. This is just proof the language supports the concepts):

#include<stdio.h>

struct foobarbaz{
    int one;
    int two;
    int three;
    int (*exampleMethod)(int, int);
};

int addTwoNumbers(int a, int b){
    return a+b;
}

int main()
{
    // Define the function pointer
    int (*pointerToFunction)(int, int) = addTwoNumbers;

    // Let's make sure we can call the pointer
    int test = (*pointerToFunction)(12,12);
    printf ("test: %u \n",  test);

    // Now, define an instance of our struct
    // and add some default values.
    struct foobarbaz fbb;
    fbb.one   = 1;
    fbb.two   = 2;
    fbb.three = 3;

    // Now add a "method"
    fbb.exampleMethod = addTwoNumbers;

    // Try calling the method
    int test2 = fbb.exampleMethod(13,36);
    printf ("test2: %u \n",  test2);

    printf("\nDone\n");
    return 0;
}

A callable is an object allows you to use round parenthesis ( ) and eventually pass some parameters, just like functions.

Every time you define a function python creates a callable object. In example, you could define the function func in these ways (it's the same):

class a(object):
    def __call__(self, *args):
        print 'Hello'

func = a()

# or ... 
def func(*args):
    print 'Hello'

You could use this method instead of methods like doit or run, I think it's just more clear to see obj() than obj.doit()

if your object class implements Serializable, you don't need to do anything else, you can pass a serializable object.
that's what i use.

Use onkeyup on the text box and check the keycode of the key pressed, if its between 65 and 90, allow else empty the text box.

RecordCount is what you want to use.

If Not temp_rst1.RecordCount > 0 ...

You can do this by writing a manifest for your jar. Have a look at the Class-Path header. Eclipse has an option for choosing your own manifest on export.

The alternative is to add the dependency to the classpath at the time you invoke the application:

win32: java.exe -cp app.jar;dependency.jar foo.MyMainClass
*nix:  java -cp app.jar:dependency.jar foo.MyMainClass

Just as an addition: This way you can access properties with names that would be otherwise unusable

$x = new StdClass;

$prop = 'a b';
$x->$prop = 1;
$x->{'x y'} = 2;
var_dump($x);

object(stdClass)#1 (2) {
  ["a b"]=>
  int(1)
  ["x y"]=>
  int(2)
}

Look at my plugin for developing swing application. It is as easy as that of netbeans': http://code.google.com/p/visualswing4eclipse/

For passing a single integer I agree with Reed Copsey's answer. If in the future you are going to pass more complicated constucts I personally like to pass all my variables as an Anonymous Type. It will look something like this:

foreach(int id in myIdsToCheck)
{
    Task.Factory.StartNew( (Object obj) => 
        {
           var data = (dynamic)obj;
           CheckFiles(data.id, theBlockingCollection,
               cancelCheckFile.Token, 
               TaskCreationOptions.LongRunning, 
               TaskScheduler.Default);
        }, new { id = id }); // Parameter value
}

You can learn more about it in my blog

Filter your log to just Error and look for FATAL EXCEPTION

This is a working bit of code.

    private void setCookie(DefaultHttpClient httpClient, String url) {
    List<Cookie> cookies = httpClient.getCookieStore().getCookies();
    if (cookies != null) {
        CookieSyncManager.createInstance(context);
        CookieManager cookieManager = CookieManager.getInstance();
        cookieManager.setAcceptCookie(true);

        for (int i = 0; i < cookies.size(); i++) {
            Cookie cookie = cookies.get(i);
            String cookieString = cookie.getName() + "=" + cookie.getValue();
            cookieManager.setCookie(url, cookieString);
        }
        CookieSyncManager.getInstance().sync();
    }
}

Here the httpclient is the DefaultHttpClient object you used in the HttpGet/HttpPost request. Also one thing to make sure is the cookie name and value, it should be given

String cookieString = cookie.getName() + "=" + cookie.getValue();

setCookie will the set the cookie for the given URL.

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

uint32_t is standard, uint32 is not. That is, if you include <inttypes.h> or <stdint.h>, you will get a definition of uint32_t. uint32 is a typedef in some local code base, but you should not expect it to exist unless you define it yourself. And defining it yourself is a bad idea.

Using array or set comparisons:

create table t (str text);
insert into t values ('AAA'), ('BBB'), ('DDD999YYY'), ('DDD099YYY');

select str from t
where str like any ('{"AAA%", "BBB%", "CCC%"}');

select str from t
where str like any (values('AAA%'), ('BBB%'), ('CCC%'));

It is also possible to do an AND which would not be easy with a regex if it were to match any order:

select str from t
where str like all ('{"%999%", "DDD%"}');

select str from t
where str like all (values('%999%'), ('DDD%'));

SnappySnippet

I finally found some time to create this tool. You can install SnappySnippet from Github. It allows easy HTML+CSS extraction from the specified (last inspected) DOM node. Additionally, you can send your code straight to CodePen or JSFiddle. Enjoy!

Other features

• cleans up HTML (removing unnecessary attributes, fixing indentation)
• optimizes CSS to make it readable
• fully configurable (all filters can be turned off)
• works with ::before and ::after pseudo-elements
• nice UI thanks to Bootstrap & Flat-UI projects

Code

SnappySnippet is open source, and you can find the code on GitHub.

Implementation

Since I've learned quite a lot while making this, I've decided to share some of the problems I've experienced and my solutions to them, maybe someone will find it interesting.

First attempt - getMatchedCSSRules()

At first I've tried retrieving the original CSS rules (coming from CSS files on the website). Quite amazingly, this is very simple thanks to window.getMatchedCSSRules(), however, it didn't work out well. The problem was that we were taking only a part of the HTML and CSS selectors that were matching in the context of the whole document, which were not matching anymore in the context of an HTML snippet. Since parsing and modifying selectors didn't seem like a good idea, I gave up on this attempt.

Second attempt - getComputedStyle()

Then, I've started from something that @CollectiveCognition suggested - getComputedStyle(). However, I really wanted to separate CSS form HTML instead of inlining all styles.

Problem 1 - separating CSS from HTML

The solution here wasn't very beautiful but quite straightforward. I've assigned IDs to all nodes in the selected subtree and used that ID to create appropriate CSS rules.

Problem 2 - removing properties with default values

Assigning IDs to the nodes worked out nicely, however I found out that each of my CSS rules has ~300 properties making the whole CSS unreadable.
Turns out that getComputedStyle() returns all possible CSS properties and values calculated for the given element. Some of them where empty, some had browser default values. To remove default values I had to get them from the browser first (and each tag has different default values). The solution was to compare the styles of the element coming from the website with the same element inserted into an empty <iframe>. The logic here was that there are no style sheets in an empty <iframe>, so each element I've appended there had only default browser styles. This way I was able to get rid of most of the properties that were insignificant.

Problem 3 - keeping only shorthand properties

Next thing I have spotted was that properties having shorthand equivalent were unnecessarily printed out (e.g. there was border: solid black 1px and then border-color: black;, border-width: 1px itd.).
To solve this I've simply created a list of properties that have shorthand equivalents and filtered them out from the results.

Problem 4 - removing prefixed properties

The number of properties in each rule was significantly lower after the previous operation, but I've found that I sill had a lot of -webkit- prefixed properties that I've never hear of (-webkit-app-region? -webkit-text-emphasis-position?).
I was wondering if I should keep any of these properties because some of them seemed useful (-webkit-transform-origin, -webkit-perspective-origin etc.). I haven't figured out how to verify this, though, and since I knew that most of the time these properties are just garbage, I decided to remove them all.

Problem 5 - combining same CSS rules

The next problem I have spotted was that the same CSS rules are repeated over and over (e.g. for each <li> with the exact same styles there was the same rule in the CSS output created).
This was just a matter of comparing rules with each other and combining these that had exactly the same set of properties and values. As a result, instead of #LI_1{...}, #LI_2{...} I got #LI_1, #LI_2 {...}.

Problem 6 - cleaning up and fixing indentation of HTML

Since I was happy with the result, I moved to HTML. It looked like a mess, mostly because the outerHTML property keeps it formatted exactly as it was returned from the server.
The only thing HTML code taken from outerHTML needed was a simple code reformatting. Since it's something available in every IDE, I was sure that there is a JavaScript library that does exactly that. And it turns out that I was right (jquery-clean). What's more, I've got unnecessary attributes removal extra (style, data-ng-repeat etc.).

Problem 7 - filters breaking CSS

Since there is a chance that in some circumstances filters mentioned above may break CSS in the snippet, I've made all of them optional. You can disable them from the Settings menu.

Deleting files and folders

If you want to delete an item from the repository, but keep it locally as an unversioned file/folder, use Extended Context Menu ? Delete (keep local). You have to hold the Shift key while right clicking on the item in the explorer list pane (right pane) in order to see this in the extended context menu.

Delete completely:
right mouse click ? Menu ? Delete

Delete & Keep local:
Shift + right mouse click ? Menu ? Delete

While you use .on(), it's basically a live query that you are using.

On the other hand, .ready (as in your case) is a static query. While using it, you can dynamically update data and do not have to wait for the page to load. You can simply pass on the values into your database (if required) when a particular value is entered.

The use of live queries is common in forms where we enter data (account or posts or even comments).

Change CI index.php file to:

if ($_SERVER['SERVER_NAME'] == 'local_server_name') {
    define('ENVIRONMENT', 'development');
} else {
    define('ENVIRONMENT', 'production');
}

if (defined('ENVIRONMENT')){
    switch (ENVIRONMENT){
        case 'development':
            error_reporting(E_ALL);
        break;

        case 'testing':
        case 'production':
            error_reporting(0);
        break;

        default:
            exit('The application environment is not set correctly.');
    }
}

IF PHP errors are off, but any MySQL errors are still going to show, turn these off in the /config/database.php file. Set the db_debug option to false:

$db['default']['db_debug'] = FALSE; 

Also, you can use active_group as development and production to match the environment https://www.codeigniter.com/user_guide/database/configuration.html

$active_group = 'development';


$db['development']['hostname'] = 'localhost';
$db['development']['username'] = '---';
$db['development']['password'] = '---';
$db['development']['database'] = '---';
$db['development']['dbdriver'] = 'mysql';
$db['development']['dbprefix'] = '';
$db['development']['pconnect'] = TRUE;

$db['development']['db_debug'] = TRUE;

$db['development']['cache_on'] = FALSE;
$db['development']['cachedir'] = '';
$db['development']['char_set'] = 'utf8';
$db['development']['dbcollat'] = 'utf8_general_ci';
$db['development']['swap_pre'] = '';
$db['development']['autoinit'] = TRUE;
$db['development']['stricton'] = FALSE;



$db['production']['hostname'] = 'localhost';
$db['production']['username'] = '---';
$db['production']['password'] = '---';
$db['production']['database'] = '---';
$db['production']['dbdriver'] = 'mysql';
$db['production']['dbprefix'] = '';
$db['production']['pconnect'] = TRUE;

$db['production']['db_debug'] = FALSE;

$db['production']['cache_on'] = FALSE;
$db['production']['cachedir'] = '';
$db['production']['char_set'] = 'utf8';
$db['production']['dbcollat'] = 'utf8_general_ci';
$db['production']['swap_pre'] = '';
$db['production']['autoinit'] = TRUE;

It works.

CSS 3 introduces the background-size property, but support is not universal.

Having the browser resize the image is inefficient though, the large image still has to be downloaded. You should resize it server side (caching the result) and use that instead. It will use less bandwidth and work in more browsers.

You may take a look at intellij code folding shortcuts.

The problem here is that you're changing your enumerator as you remove items from the list. This isn't valid with a 'foreach' loop. But just about any other type of loop will be OK.

So you could try something like this:

for(int i=0; i < listBox1.Items.Count; )
{
    string removelistitem = "OBJECT";
    if(listBox1.Items[i].Contains(removelistitem))
         listBox1.Items.Remove(item);
    else
        ++i;
}

Piece of cake.

Use 960Grids Go to the automatic layout builder and make a two column, fluid design. Build a left column to the width of grids that works....this is the only challenge using grids and it's very easy once you read a tutorial. In a nutshell, each column in a grid is a certain width, and you set the amount of columns you want to use. To get a column that's exactly a certain width, you have to adjust your math so that your column width is exact. Not too tough.

No chance of wrapping because others have already fought that battle for you. Compatibility back as far as you likely will ever need to go. Quick and easy....Now, download, customize and deploy.

Voila. Grids FTW.

Something like:

function populate(selector) {
  $(selector)
    .append('<option value="foo">foo</option>')
    .append('<option value="bar">bar</option>')
}

populate('#myform .myselect');

Or even:

$.fn.populate = function() {
  $(this)
    .append('<option value="foo">foo</option>')
    .append('<option value="bar">bar</option>')
}

$('#myform .myselect').populate();

Generally a parameter is what appears in the definition of the method. An argument is the instance passed to the method during runtime.

An oblique answer to the question is to write all the code as classes, apart from the index.php files, which are then the only points of entry. PHP files that contain classes will not cause anything to happen, even if they are invoked directly through Apache.

A direct answer is to include the following in .htaccess:

<FilesMatch "\.php$">
    Order Allow,Deny
    Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

This will allow any file like index.php, index2.php etc to be accessed, but will refuse access of any kind to other .php files. It will not affect other file types.

Just an important note: the accepted answer above will not work correctly for keyCode >= 144, i.e. period, comma, dash, etc. For those you should use a more general algorithm:

let chrCode = keyCode - 48 * Math.floor(keyCode / 48);
let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);

If you're curious as to why, this is apparently necessary because of the behavior of the built-in JS function String.fromCharCode(). For values of keyCode <= 96 it seems to map using the function:

chrCode = keyCode - 48 * Math.floor(keyCode / 48)

For values of keyCode > 96 it seems to map using the function:

chrCode = keyCode

If this seems like odd behavior then well..I agree. Sadly enough, it would be very far from the weirdest thing I've seen in the JS core.

document.onkeydown = function(e) {_x000D_
    let keyCode = e.keyCode;_x000D_
    let chrCode = keyCode - 48 * Math.floor(keyCode / 48);_x000D_
    let chr = String.fromCharCode((96 <= keyCode) ? chrCode: keyCode);_x000D_
    console.log(chr);_x000D_
};

<input type="text" placeholder="Focus and Type"/>

You can use data-* attribute to embed custom data. The data-* attributes gives us the ability to embed custom data attributes on all HTML elements.

jQuery .data() method allows you to get/set data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks.

jQuery .attr() method get/set attribute value for only the first element in the matched set.

Example:

<span id="test" title="foo" data-kind="primary">foo</span>

$("#test").attr("title");
$("#test").attr("data-kind");
$("#test").data("kind");
$("#test").data("value", "bar");

On Unix Systems (including GNU/Linux, macOS, and BSD)

Use nohup mypythonprog &, and you can close the terminal window without disrupting the process. You can also run exit if you are running in the cloud and don't want to leave a hanging shell process.

On Windows Systems

Save the program with a .pyw extension and now it will open with pythonw.exe. No shell window.

For example, if you have foo.py, you need to rename it to foo.pyw.

Your declaration is int ttTreeInsert(int value);

However, your definition/implementation is

ttTree::ttTreeInsert(int value)
{
}

Notice that the return type int is missing in the implementation. Instead it should be

int ttTree::ttTreeInsert(int value)
{
    return 1; // or some valid int
}

I never had any luck with that approach. I always do this (hope this helps):

var obj = {};

obj.first_name = $("#namec").val();
obj.last_name = $("#surnamec").val();
obj.email = $("#emailc").val();
obj.mobile = $("#numberc").val();
obj.password = $("#passwordc").val();

Then in your ajax:

$.ajax({
        type: "POST",
        url: hb_base_url + "consumer",
        contentType: "application/json",
        dataType: "json",
        data: JSON.stringify(obj),
        success: function(response) {
            console.log(response);
        },
        error: function(response) {
            console.log(response);
        }
    });

random_state number splits the test and training datasets with a random manner. In addition to what is explained here, it is important to remember that random_state value can have significant effect on the quality of your model (by quality I essentially mean accuracy to predict). For instance, If you take a certain dataset and train a regression model with it, without specifying the random_state value, there is the potential that everytime, you will get a different accuracy result for your trained model on the test data. So it is important to find the best random_state value to provide you with the most accurate model. And then, that number will be used to reproduce your model in another occasion such as another research experiment. To do so, it is possible to split and train the model in a for-loop by assigning random numbers to random_state parameter:

for j in range(1000):

            X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =j,     test_size=0.35)
            lr = LarsCV().fit(X_train, y_train)

            tr_score.append(lr.score(X_train, y_train))
            ts_score.append(lr.score(X_test, y_test))

        J = ts_score.index(np.max(ts_score))

        X_train, X_test, y_train, y_test = train_test_split(X, y , random_state =J, test_size=0.35)
        M = LarsCV().fit(X_train, y_train)
        y_pred = M.predict(X_test)`

As @Kimble has said, with Jackson 2, using the default formatting is very easy; simply register JodaModule on your ObjectMapper.

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JodaModule());

For custom serialization/de-serialization of DateTime, you need to implement your own StdScalarSerializer and StdScalarDeserializer; it's pretty convoluted, but anyway.

For example, here's a DateTime serializer that uses the ISODateFormat with the UTC time zone:

public class DateTimeSerializer extends StdScalarSerializer<DateTime> {

    public DateTimeSerializer() {
        super(DateTime.class);
    }

    @Override
    public void serialize(DateTime dateTime,
                          JsonGenerator jsonGenerator,
                          SerializerProvider provider) throws IOException, JsonGenerationException {
        String dateTimeAsString = ISODateTimeFormat.withZoneUTC().print(dateTime);
        jsonGenerator.writeString(dateTimeAsString);
    }
}

And the corresponding de-serializer:

public class DateTimeDesrializer extends StdScalarDeserializer<DateTime> {

    public DateTimeDesrializer() {
        super(DateTime.class);
    }

    @Override
    public DateTime deserialize(JsonParser jsonParser,
                                DeserializationContext deserializationContext) throws IOException, JsonProcessingException {
        try {
            JsonToken currentToken = jsonParser.getCurrentToken();
            if (currentToken == JsonToken.VALUE_STRING) {
                String dateTimeAsString = jsonParser.getText().trim();
                return ISODateTimeFormat.withZoneUTC().parseDateTime(dateTimeAsString);
            }
        } finally {
            throw deserializationContext.mappingException(getValueClass());
        }
    }

Then tie these together with a module:

public class DateTimeModule extends SimpleModule {

    public DateTimeModule() {
        super();
        addSerializer(DateTime.class, new DateTimeSerializer());
        addDeserializer(DateTime.class, new DateTimeDeserializer());
    }
}

Then register the module on your ObjectMapper:

ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new DateTimeModule());

All the random methods end up calling random.random() so the best way is to call it directly:

[int(1000*random.random()) for i in xrange(10000)]

For example,

• random.randint calls random.randrange.
• random.randrange has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n).

NumPy is much faster still of course.

It seems to me that you are not very familiar with interfaces. In the code you have posted, you don't need to implement AutoCloseable.

You only have to (or should) implement Closeable or AutoCloseable if you are about to implement your own PrintWriter, which handles files or any other resources which needs to be closed.

In your implementation, it is enough to call pw.close(). You should do this in a finally block:

PrintWriter pw = null;
try {
   File file = new File("C:\\test.txt");
   pw = new PrintWriter(file);
} catch (IOException e) {
   System.out.println("bad things happen");
} finally {
   if (pw != null) {
      try {
         pw.close();
      } catch (IOException e) {
      }
   }
}

The code above is Java 6 related. In Java 7 this can be done more elegantly (see this answer).

Please use following php function to convert php stdClass to array

The terms of BYTE and WORD are relative to the size of the processor that is being referred to. The most common processors are/were 8 bit, 16 bit, 32 bit or 64 bit. These are the WORD lengths of the processor. Actually half of a WORD is a BYTE, whatever the numerical length is. Ready for this, half of a BYTE is a NIBBLE.

Here is a very useful and lightweight javascript plugin to accomplish this: js-cookie

Cookies.set('cookieName', 'Value');
      setTimeout(function(){
        var cookieValue =  Cookies.get('cookieName');
        if(cookieValue){
           console.log("Test Cookie is set!");
        } else {
           document.write('<p>Sorry, but cookies must be enabled</p>');
        }
        Cookies.remove('cookieName');
      }, 1000);

Works in all browsers, accepts any character.

I'll add a bit hint: it seems what you pass as the key value of a header depends on your authorization type, in my case that was PRIVATE-TOKEN

header = {'PRIVATE-TOKEN': 'my_token'}
response = requests.get(myUrl, headers=header)

I like @huynhjl's answer, it led me down the right path. However, it isn't great at handling error conditions. If the desired node does not exist, you get a cast exception. I've adapted this slightly to make use of Option to better handle this.

class CC[T] {
  def unapply(a:Option[Any]):Option[T] = if (a.isEmpty) {
    None
  } else {
    Some(a.get.asInstanceOf[T])
  }
}

object M extends CC[Map[String, Any]]
object L extends CC[List[Any]]
object S extends CC[String]
object D extends CC[Double]
object B extends CC[Boolean]

for {
  M(map) <- List(JSON.parseFull(jsonString))
  L(languages) = map.get("languages")
  language <- languages
  M(lang) = Some(language)
  S(name) = lang.get("name")
  B(active) = lang.get("is_active")
  D(completeness) = lang.get("completeness")
} yield {
  (name, active, completeness)
}

Of course, this doesn't handle errors so much as avoid them. This will yield an empty list if any of the json nodes are missing. You can use a match to check for the presence of a node before acting...

for {
  M(map) <- Some(JSON.parseFull(jsonString))
} yield {
  map.get("languages") match {
    case L(languages) => {
      for {
        language <- languages
        M(lang) = Some(language)
        S(name) = lang.get("name")
        B(active) = lang.get("is_active")
        D(completeness) = lang.get("completeness")
      } yield {
        (name, active, completeness)
      }        
    }
    case None => "bad json"
  }
}

user: USER

this.user = ({} as USER)

The message updates you receive via getUpdates or your webhook will contain the chat ID for the specific message. It will be contained under the message.chat.id key.

This seems like the only way you are able to retrieve the chat ID. So if you want to write something where the bot initiates the conversation you will probably have to store the chat ID in relation to the user in some sort of key->value store like MemCache or Redis.

I believe their documentation suggests something similar here, https://core.telegram.org/bots#deep-linking-example. You can use deep-linking to initiate a conversation without requiring the user to type a message first.

The direct way of doing this is to create triggers on tables. Set some conditions or mapping methods. When update or delete occurs, it will insert into 'change' table automatically.

But the biggest part is what if we got lots columns and lots of table. We have to type every column's name of every table. Obviously, It's waste of time.

To handle this more gorgeously, we can create some procedures or functions to retrieve name of columns.

We can also use 3rd-part tool simply to do this. Here, I write a java program Mysql Tracker

Use this command, in command prompt

sqlplus userName/password@host/serviceName

Lots of options here, but one of the easiest to follow is subset. Consider:

> set.seed(43)
> df <- data.frame(name = sample(letters, 100, TRUE), date = sample(1:500, 100, TRUE))
> 
> subset(df, date > 5 & date < 15)
   name date
11    k   10
67    y   12
86    e    8

You can also insert logic directly into the index for your data.frame. The comma separates the rows from columns. We just have to remember that R indexes rows first, then columns. So here we are saying rows with date > 5 & < 15 and then all columns:

df[df$date > 5 & df$date < 15 ,]

I'd also recommend checking out the help pages for subset, ?subset and the logical operators ?"&"

list(data_set.itertuples(index=False))

As of 17.1, the above will return a list of namedtuples.

If you want a list of ordinary tuples, pass name=None as an argument:

list(data_set.itertuples(index=False, name=None))

I'm guessing that when you enter a value into the totals field that value expression somehow gets overwritten.

However, you can take an alternative approach: Create a field for the total value and when either one or two changes update that field.

<li>Total <input type="text" ng-model="total">{{total}}</li>

And change the javascript:

function TodoCtrl($scope) {
    $scope.$watch('one * two', function (value) {
        $scope.total = value;
    });
}

Example fiddle here.

Another way to achieve this is using old printf() function of C language

You can use this like

int dd = 1, mm = 9, yy = 1;
printf("%02d - %02d - %04d", mm, dd, yy);

This will print 09 - 01 - 0001 on the console.

You can also use another function sprintf() to write formatted output to a string like below:

int dd = 1, mm = 9, yy = 1;
char s[25];
sprintf(s, "%02d - %02d - %04d", mm, dd, yy);
cout << s;

Don't forget to include stdio.h header file in your program for both of these functions

Thing to be noted:

You can fill blank space either by 0 or by another char (not number).
If you do write something like %24d format specifier than this will not fill 2 in blank spaces. This will set pad to 24 and will fill blank spaces.

Found this elsewhere here but this is a simple solution that works:

 WITH cte AS /* Declaring a new table named 'cte' to be a clone of your table */
 (SELECT *, ROW_NUMBER() OVER (PARTITION BY id ORDER BY val1 DESC) AS rn
 FROM MyTable /* Selecting only unique values based on the "id" field */
 )
 SELECT * /* Here you can specify several columns to retrieve */
 FROM cte
 WHERE rn = 1

Modifying styles directly in range or cells did not work for me. But the idea to:

1. create a separate style
2. apply all the necessary style property values
3. set the style's name to the Style property of the range

, given in MSDN How to: Programmatically Apply Styles to Ranges in Workbooks did the job.

For example:

var range = worksheet.Range[string.Format("A{0}:C{0}", rowIndex++)];
range.Merge();
range.Value = "some value";

var style = workbook.AddStyle();
style.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;

range.Style = style.Name;

While dragging the TextBox it self Press F4 for Properties and under the Textmode set to Multiline, The representation of multiline to a text box is it can be sizable at 6 sides. And no need to include any newline characters for getting multiline. May be you set it multiline but you dint increased the size of the Textbox at design time.

params = { :irrelevant => "A String",
           :choice1 => "Oh look, another one",
           :choice2 => "Even more strings",
           :choice3 => "But wait",
           :irrelevant2 => "The last string" }

choices = params.select { |key, value| key.to_s[/^choice\d+/] }
#=> {:choice1=>"Oh look, another one", :choice2=>"Even more strings", :choice3=>"But wait"}

A slightly more readable alternative solution:
sys.stdout.write(code.ljust(5) + name.ljust(20) + industry)

Note that ljust(#ofchars) uses fixed width characters and doesn't dynamically adjust like the other solutions.

You don't add columns between other columns in SQL, you just add them. Where they're put is totally up to the DBMS. The right place to ensure that columns come out in the correct order is when you select them.

In other words, if you want them in the order {name,colnew,qty,rate}, you use:

select name, colnew, qty, rate from ...

With SQLite, you need to use alter table, an example being:

alter table mytable add column colnew char(50)

Sometimes margin-top can causes design problems:

http://www.w3.org/TR/CSS2/box.html#collapsing-margins

So, i recommend create "margin-bottom classes" instead of "margin-top classes" and apply them to the previous item.

If you are using Bootstrap importing LESS Bootstrap files try to define the margin-bottom classes with proportional Bootstrap Theme spaces:

.margin-bottom-xs {margin-bottom: ceil(@line-height-computed / 4);}  
.margin-bottom-sm {margin-bottom: ceil(@line-height-computed / 2);} 
.margin-bottom-md {margin-bottom: @line-height-computed;}
.margin-bottom-lg {margin-bottom: ceil(@line-height-computed * 2);}  

Below you find the solution I used in a project. Instead forEach just use allMatch:

someObjects.allMatch(obj -> {
    return !some_condition_met;
});

Create a separate JavaScript function that can be called to close the dialog using the specific object id, and place the function outside of $(document).ready() like this:

function closeDialogWindow() { 
$('#dialogWindow').dialog('close');
}

NOTE: The function must be declared outside of $(document).ready() so jQuery doesn't try to trigger the close event on the dialog before it is created in the DOM.

When in a static method you use a variable, the variable have to be static too as an example:

private static int a=0;  
public static void testMethod() {  
        a=1;  
}

xrange uses an iterator (generates values on the fly), range returns a list.

First off, RangeToHTML. The script calls it like a method, but it isn't. It's a popular function by MVP Ron de Bruin. Coincidentally, that links points to the exact source of the script you posted, before those few lines got b?u?t?c?h?e?r?e?d? modified.

On with Range.SpecialCells. This method operates on a range and returns only those cells that match the given criteria. In your case, you seem to be only interested in the visible text cells. Importantly, it operates on a Range, not on HTML text.

For completeness sake, I'll post a working version of the script below. I'd certainly advise to disregard it and revisit the excellent original by Ron the Bruin.

In Axis webservice and if you have to disable the certificate checking then use below code:

AxisProperties.setProperty("axis.socketSecureFactory","org.apache.axis.components.net.SunFakeTrustSocketFactory");

In the spirit of a DVCS (as in "Distributed"), you don't cancel something you have published:
Pull requests are essentially patches you have send (normally by email, here by GitHub webapp), and you wouldn't cancel an email either ;)

But since the GitHub Pull Request system also includes a discussion section, that would be there that you could voice your concern to the recipient of those changes, asking him/her to disregards 29 of your 30 commits.

Finally, remember:

• a/ you have a preview section when making a pull request, allowing you to see the number of commits about to be included in it, and to review their diff.
• b/ it is preferable to rebase the work you want to publish as pull request on top of the remote branch which will receive said work. Then you can make a pull request which could be safely applied in a fast forward manner by the recipient.

That being said, since January 2011 ("Refreshed Pull Request Discussions"), and mentioned in the answer above, you can close a pull request in the comments.
Look for that "Comment and Close" button at the bottom of the discussion page:

Use STATS option: http://msdn.microsoft.com/en-us/library/ms186865.aspx

You have probably forgotten to restart apache/wamp/xamp/whatever webserver you use, you need to do that in order to make it work

encodeURIComponent()

Converts the input into a URL-encoded string

encodeURI()

URL-encodes the input, but assumes a full URL is given, so returns a valid URL by not encoding the protocol (e.g. http://) and host name (e.g. www.stackoverflow.com).

decodeURIComponent() and decodeURI() are the opposite of the above

If you need table with the border, I suggest linear layout with weight instead of TableLayout.

Actually wrapping of text happens automatically in tables. The blunder people commit while testing is to hypothetically assume a long string like "ggggggggggggggggggggggggggggggggggggggggggggggg" and complain that it doesn't wrap. Practically there is no word in English that is this long and even if there is, there is a faint chance that it will be used within that <td>.

Try testing with sentences like "Counterposition is superstitious in predetermining circumstances".

I think I know where your question is headed. And since this question is the one that pop ups in google's search main results, I can give a plain answer on what the @Valid annotation does.

I'll present 3 scenarios on how I've used @Valid

Model:

public class Employee{
private String name;
@NotNull(message="cannot be null")
@Size(min=1, message="cannot be blank")
private String lastName;
 //Getters and Setters for both fields.
 //...
}

JSP:

...
<form:form action="processForm" modelAttribute="employee">
 <form:input type="text" path="name"/>
 <br>
 <form:input type="text" path="lastName"/>
<form:errors path="lastName"/>
<input type="submit" value="Submit"/>
</form:form>
...

Controller for scenario 1:

     @RequestMapping("processForm")
        public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
        return "employee-confirmation-page";
    }

In this scenario, after submitting your form with an empty lastName field, you'll get an error page since you're applying validation rules but you're not handling it whatsoever.

Example of said error: Exception page

Controller for scenario 2:

 @RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee,
BindingResult bindingResult){
                return bindingResult.hasErrors() ? "employee-form" : "employee-confirmation-page";
            }

In this scenario, you're passing all the results from that validation to the bindingResult, so it's up to you to decide what to do with the validation results of that form.

Controller for scenario 3:

@RequestMapping("processForm")
    public String processFormData(@Valid @ModelAttribute("employee") Employee employee){
                return "employee-confirmation-page";
            }
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public Map<String, String> invalidFormProcessor(MethodArgumentNotValidException ex){
  //Your mapping of the errors...etc
}

In this scenario you're still not handling the errors like in the first scenario, but you pass that to another method that will take care of the exception that @Valid triggers when processing the form model. Check this see what to do with the mapping and all that.

To sum up: @Valid on its own with do nothing more that trigger the validation of validation JSR 303 annotated fields (@NotNull, @Email, @Size, etc...), you still need to specify a strategy of what to do with the results of said validation.

Hope I was able to clear something for people that might stumble with this.

You can use sed:

sed -i 's/abc/XYZ/gi' /tmp/file.txt

You can use find and sed if you don't know your filename:

find ./ -type f -exec sed -i 's/abc/XYZ/gi' {} \;

Find and replace in all Python files:

find ./ -iname "*.py" -type f -exec sed -i 's/abc/XYZ/gi' {} \;

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

Solved the problem by upgrading the dependency to below version

Based on what type of RFC standard encoding you want to perform or if you need to customize your encoding you might want to create your own class.

/**
 * UrlEncoder make it easy to encode your URL
 */
class UrlEncoder{
    public const STANDARD_RFC1738 = 1;
    public const STANDARD_RFC3986 = 2;
    public const STANDARD_CUSTOM_RFC3986_ISH = 3;
    // add more here

    static function encode($string, $rfc){
        switch ($rfc) {
            case self::STANDARD_RFC1738:
                return  urlencode($string);
                break;
            case self::STANDARD_RFC3986:
                return rawurlencode($string);
                break;
            case self::STANDARD_CUSTOM_RFC3986_ISH:
                // Add your custom encoding
                $entities = ['%21', '%2A', '%27', '%28', '%29', '%3B', '%3A', '%40', '%26', '%3D', '%2B', '%24', '%2C', '%2F', '%3F', '%25', '%23', '%5B', '%5D'];
                $replacements = ['!', '*', "'", "(", ")", ";", ":", "@", "&", "=", "+", "$", ",", "/", "?", "%", "#", "[", "]"];
                return str_replace($entities, $replacements, urlencode($string));
                break;
            default:
                throw new Exception("Invalid RFC encoder - See class const for reference");
                break;
        }
    }
}

Use example:

$dataString = "https://www.google.pl/search?q=PHP is **great**!&id=123&css=#kolo&[email protected])";

$dataStringUrlEncodedRFC1738 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC1738);
$dataStringUrlEncodedRFC3986 = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_RFC3986);
$dataStringUrlEncodedCutom = UrlEncoder::encode($dataString, UrlEncoder::STANDARD_CUSTOM_RFC3986_ISH);

Will output:

string(126) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP+is+%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"
string(130) "https%3A%2F%2Fwww.google.pl%2Fsearch%3Fq%3DPHP%20is%20%2A%2Agreat%2A%2A%21%26id%3D123%26css%3D%23kolo%26email%3Dme%40liszka.com%29"
string(86)  "https://www.google.pl/search?q=PHP+is+**great**!&id=123&css=#kolo&[email protected])"

This is Correct way to get ##

function getTime(offset)
        {
            var d = new Date();
            localTime = d.getTime();
            localOffset = d.getTimezoneOffset() * 60000;

            // obtain UTC time in msec
            utc = localTime + localOffset;
            // create new Date object for different city
            // using supplied offset
            var nd = new Date(utc + (3600000*offset));
            //nd = 3600000 + nd;
            utc = new Date(utc);
            // return time as a string
            $("#local").html(nd.toLocaleString());
            $("#utc").html(utc.toLocaleString());
        }

Yes, I also found it here: http://developer.android.com/tools/testing/activity_testing.html It's seems a key-input protection mechanism which includes the screen-lock, but not only includes it. According to this webpage, it also defines some key-input restriction for auto-test framework in Android.

event.target returns the node that was targeted by the function. This means you can do anything you want to do with any other node like one you'd get from document.getElementById

I'm tried with jQuery

var _target = e.target;
console.log(_target.attr('href'));

Return an error :

.attr not function

But _target.attributes.href.value was works.

db.collection.find({$and:
  [
    {date_time:{$gt:ISODate("2020-06-01T00:00:00.000Z")}},
     {date_time:{$lt:ISODate("2020-06-30T00:00:00.000Z")}}
   ]
 })

##In case you are making the query directly from your application ##

db.collection.find({$and:
   [
     {date_time:{$gt:"2020-06-01T00:00:00.000Z"}},
     {date_time:{$lt:"2020-06-30T00:00:00.000Z"}}
  ]

 })

A simple way is to add

.center_div{
    margin: 0 auto;
    width:80% /* value of your choice which suits your alignment */
}

to you class .container.Add width:xx % to it and you get perfectly centered div!

eg :

<div class="container center_div">

but i feel that by default container is centered in BS!

I wrote a little 2,2kb library of saving image in localStorage JQueryImageCaching Usage:

<img data-src="path/to/image">
<script>
    $('img').imageCaching();
</script>

The extra backslash is not actually added; it's just added by the repr() function to indicate that it's a literal backslash. The Python interpreter uses the repr() function (which calls __repr__() on the object) when the result of an expression needs to be printed:

>>> '\\'
'\\'
>>> print '\\'
\
>>> print '\\'.__repr__()
'\\'

I had a similar problem, which led me here:

$ phpunit --version

Unlike the above, installing the software did not resolve my problem because I already had it.

I found my solution via : Debian Bug report logs

$ sudo vim /etc/php5/mods-available/uprofiler.ini

I edited the ini file, changing extension=profiler.so to extension=uprofiler.so .... the result, happily:

i.e. no more warning.

Same can be done with async await and arrow function

server.get('/usersList', async (req, res) => {

const users = await User.find({});

const userMap = {};
users.forEach((user) => {
    userMap[user._id] = user;
});

res.send(userMap);

});

No matter what state your repo is in you can always reset to any previous commit:

git reset --hard <commit hash>

This will discard all changes which were made after that commit.

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

I just updated AngularJs to 1.1.2 and have no problem with it. I guess this bug was fixed.

http://ci.angularjs.org/job/angular.js-pete/57/artifact/build/angular.js

Make sure you have correct jsp file name in web.xml file. By replacing default .jsp filename in web.xml with my current filename solved the problem

If your parameter value is not fixed or your value can be null based on business you can try the following approach.

DECLARE @DrugClassstring VARCHAR(MAX);
SET @DrugClassstring = 'C3,C2'; -- You can pass null also

---------------------------------------------

IF @DrugClassstring IS NULL 
    SET @DrugClassstring = 'C3,C2,C4,C5,RX,OT'; -- If null you can set your all conditional case that will return for all
SELECT dn.drugclass_FK , dn.cdrugname
FROM drugname AS dn
INNER JOIN dbo.SplitString(@DrugClassstring, ',') class ON dn.drugclass_FK = class.[Name] -- SplitString is a a function

         DECLARE @name NVARCHAR(255);
         DECLARE @pos INT;
         WHILE CHARINDEX(@delimeter, @stringToSplit) > 0
             BEGIN
                 SELECT @pos = CHARINDEX(@delimeter, @stringToSplit);
                 SELECT @name = SUBSTRING(@stringToSplit, 1, @pos-1);
                 INSERT INTO @returnList
                        SELECT @name;
                 SELECT @stringToSplit = SUBSTRING(@stringToSplit, @pos+1, LEN(@stringToSplit)-@pos);
             END;
         INSERT INTO @returnList
                SELECT @stringToSplit;
         RETURN;
     END;

Though this is an old question, there's still one problem that I don't see anybody having addressed at all: garbage collection is almost impossible to specify.

In particular, the C++ standard is quite careful to specify the language in terms of externally observable behavior, rather than how the implementation achieves that behavior. In the case of garbage collection, however, there is virtually no externally observable behavior.

The general idea of garbage collection is that it should make a reasonable attempt at assuring that a memory allocation will succeed. Unfortunately, it's essentially impossible to guarantee that any memory allocation will succeed, even if you do have a garbage collector in operation. This is true to some extent in any case, but particularly so in the case of C++, because it's (probably) not possible to use a copying collector (or anything similar) that moves objects in memory during a collection cycle.

If you can't move objects, you can't create a single, contiguous memory space from which to do your allocations -- and that means your heap (or free store, or whatever you prefer to call it) can, and probably will, become fragmented over time. This, in turn, can prevent an allocation from succeeding, even when there's more memory free than the amount being requested.

While it might be possible to come up with some guarantee that says (in essence) that if you repeat exactly the same pattern of allocation repeatedly, and it succeeded the first time, it will continue to succeed on subsequent iterations, provided that the allocated memory became inaccessible between iterations. That's such a weak guarantee it's essentially useless, but I can't see any reasonable hope of strengthening it.

Even so, it's stronger than what has been proposed for C++. The previous proposal [warning: PDF] (that got dropped) didn't guarantee anything at all. In 28 pages of proposal, what you got in the way of externally observable behavior was a single (non-normative) note saying:

[ Note: For garbage collected programs, a high quality hosted implementation should attempt to maximize the amount of unreachable memory it reclaims. —end note ]

At least for me, this raises a serious question about return on investment. We're going to break existing code (nobody's sure exactly how much, but definitely quite a bit), place new requirements on implementations and new restrictions on code, and what we get in return is quite possibly nothing at all?

Even at best, what we get are programs that, based on testing with Java, will probably require around six times as much memory to run at the same speed they do now. Worse, garbage collection was part of Java from the beginning -- C++ places enough more restrictions on the garbage collector that it will almost certainly have an even worse cost/benefit ratio (even if we go beyond what the proposal guaranteed and assume there would be some benefit).

I'd summarize the situation mathematically: this a complex situation. As any mathematician knows, a complex number has two parts: real and imaginary. It appears to me that what we have here are costs that are real, but benefits that are (at least mostly) imaginary.

I was having the same problem, none of the posted solutions helped. Finally, I figured out what I was doing wrong. When I installed the Java JDK it asked me for a directiy where I wanted to install. I changed the directory to where I wanted the code to go. It then asked for a directory where it could install the Runtime Environment and I selected the SAME DIRECTORY where I installed the JDK. It over wrote my lib folder and erased the tools.jar. Be sure to use different folders during the install. I used my custom folder for the JDK and the default folder for the RE and everything worked fine.

--- UPDATE 3 --- (does not conflict with UPDATE 2)

Considering the case that windows users prefer working on CRLF and linux/mac users prefer working on LF on text files. Providing the answer from the perspective of a repository maintainer:

For me the best strategy(less problems to solve) is: keep all text files with LF inside git repo even if you are working on a windows-only project. Then give the freedom to clients to work on the line-ending style of their preference, provided that they pick a core.autocrlf property value that will respect your strategy (LF on repo) while staging files for commit.

Staging is what many people confuse when trying to understand how newline strategies work. It is essential to undestand the following points before picking the correct value for core.autocrlf property:

• Adding a text file for commit (staging it) is like copying the file to another place inside .git/ sub-directory with converted line-endings (depending on core.autocrlf value on your client config). All this is done locally.
• setting core.autocrlf is like providing an answer to the question (exact same question on all OS):
  • "Should git-client a. convert LF-to-CRLF when checking-out (pulling) the repo changes from the remote or b. convert CRLF-to-LF when adding a file for commit?" and the possible answers (values) are:
  • false: "do none of the above",
  • input: "do only b"
  • true: "do a and and b"
  • note that there is NO "do only a"

Fortunately

• git client defaults (windows: core.autocrlf: true, linux/mac: core.autocrlf: false) will be compatible with LF-only-repo strategy.
  Meaning: windows clients will by default convert to CRLF when checking-out the repository and convert to LF when adding for commit. And linux clients will by default not do any conversions. This theoretically keeps your repo lf-only.

Unfortunately:

• There might be GUI clients that do not respect the git core.autocrlf value
• There might be people that don't use a value to respect your lf-repo strategy. E.g. they use core.autocrlf=false and add a file with CRLF for commit.

To detect ASAP non-lf text files committed by the above clients you can follow what is described on --- update 2 ---: (git grep -I --files-with-matches --perl-regexp '\r' HEAD, on a client compiled using: --with-libpcre flag)

And here is the catch:. I as a repo maintainer keep a git.autocrlf=input so that I can fix any wrongly committed files just by adding them again for commit. And I provide a commit text: "Fixing wrongly committed files".

As far as .gitattributes is concearned. I do not count on it, because there are more ui clients that do not understand it. I only use it to provide hints for text and binary files, and maybe flag some exceptional files that should everywhere keep the same line-endings:

*.java          text !eol # Don't do auto-detection. Treat as text (don't set any eol rule. use client's)
*.jpg           -text     # Don't do auto-detection. Treat as binary
*.sh            text eol=lf # Don't do auto-detection. Treat as text. Checkout and add with eol=lf
*.bat           text eol=crlf # Treat as text. Checkout and add with eol=crlf

Question: But why are we interested at all in newline handling strategy?

Answer: To avoid a single letter change commit, appear as a 5000-line change, just because the client that performed the change auto-converted the full file from crlf to lf (or the opposite) before adding it for commit. This can be rather painful when there is a conflict resolution involved. Or it could in some cases be the cause of unreasonable conflicts.

--- UPDATE 2 ---

The dafaults of git client will work in most cases. Even if you only have windows only clients, linux only clients or both. These are:

• windows: core.autocrlf=true means convert lines to CRLF on checkout and convert lines to LF when adding files.
• linux: core.autocrlf=input means don't convert lines on checkout (no need to since files are expected to be committed with LF) and convert lines to LF (if needed) when adding files. (-- update3 -- : Seems that this is false by default, but again it is fine)

The property can be set in different scopes. I would suggest explicitly setting in the --global scope, to avoid some IDE issues described at the end.

git config core.autocrlf
git config --global core.autocrlf
git config --system core.autocrlf
git config --local core.autocrlf
git config --show-origin core.autocrlf

Also I would strongly discourage using on windows git config --global core.autocrlf false (in case you have windows only clients) in contrast to what is proposed to git documentation. Setting to false will commit files with CRLF in the repo. But there is really no reason. You never know whether you will need to share the project with linux users. Plus it's one extra step for each client that joins the project instead of using defaults.

Now for some special cases of files (e.g. *.bat *.sh) which you want them to be checked-out with LF or with CRLF you can use .gitattributes

To sum-up for me the best practice is:

• Make sure that every non-binary file is committed with LF on git repo (default behaviour).
• Use this command to make sure that no files are committed with CRLF: git grep -I --files-with-matches --perl-regexp '\r' HEAD (Note: on windows clients works only through git-bash and on linux clients only if compiled using --with-libpcre in ./configure).
• If you find any such files by executing the above command, correct them. This in involves (at least on linux):
  • set core.autocrlf=input (--- update 3 --)
  • change the file
  • revert the change(file is still shown as changed)
  • commit it
• Use only the bare minimum .gitattributes
• Instruct the users to set the core.autocrlf described above to its default values.
• Do not count 100% on the presence of .gitattributes. git-clients of IDEs may ignore them or treat them differrently.

As said some things can be added in git attributes:

# Always checkout with LF
*.sh            text eol=lf
# Always checkout with CRLF
*.bat           text eol=crlf

I think some other safe options for .gitattributes instead of using auto-detection for binary files:

• -text (e.g for *.zip or *.jpg files: Will not be treated as text. Thus no line-ending conversions will be attempted. Diff might be possible through conversion programs)
• text !eol (e.g. for *.java,*.html: Treated as text, but eol style preference is not set. So client setting is used.)
• -text -diff -merge (e.g for *.hugefile: Not treated as text. No diff/merge possible)

--- PREVIOUS UPDATE ---

One painful example of a client that will commit files wrongly:

netbeans 8.2 (on windows), will wrongly commit all text files with CRLFs, unless you have explicitly set core.autocrlf as global. This contradicts to the standard git client behaviour, and causes lots of problems later, while updating/merging. This is what makes some files appear different (although they are not) even when you revert.
The same behaviour in netbeans happens even if you have added correct .gitattributes to your project.

Using the following command after a commit, will at least help you detect early whether your git repo has line ending issues: git grep -I --files-with-matches --perl-regexp '\r' HEAD

I have spent hours to come up with the best possible use of .gitattributes, to finally realize, that I cannot count on it.
Unfortunately, as long as JGit-based editors exist (which cannot handle .gitattributes correctly), the safe solution is to force LF everywhere even on editor-level.

• windows/linux clients: core.autocrlf=input

• committed .gitattributes: * text=auto eol=lf

• committed .editorconfig (http://editorconfig.org/) which is kind of standardized format, combined with editor plugins:

  • https://github.com/editorconfig/
  • https://github.com/welovecoding/editorconfig-netbeans/

In case anyone was wondering - it was probably my css...

  src: url('bingo.eot')
  src: local('bingo')
  src: url('bingo.svg#bingo') format('svg')
  src: url('bingo.otf') format('opentype')

will render as

@font-face {
  font-family: "bingo";
  src: url('bingo.eot');
  src: local('bingo');
  src: url('bingo.svg#bingo') format('svg');
  src: url('bingo.otf') format('opentype'); }

which seems to be close enough... just need to check the SVG rendering

As the documentation says, a Vector and an ArrayList are almost equivalent. The difference is that access to a Vector is synchronized, whereas access to an ArrayList is not. What this means is that only one thread can call methods on a Vector at a time, and there's a slight overhead in acquiring the lock; if you use an ArrayList, this isn't the case. Generally, you'll want to use an ArrayList; in the single-threaded case it's a better choice, and in the multi-threaded case, you get better control over locking. Want to allow concurrent reads? Fine. Want to perform one synchronization for a batch of ten writes? Also fine. It does require a little more care on your end, but it's likely what you want. Also note that if you have an ArrayList, you can use the Collections.synchronizedList function to create a synchronized list, thus getting you the equivalent of a Vector.

File.Create(string) returns an instance of the FileStream class. You can call the Stream.Close() method on this object in order to close it and release resources that it's using:

var myFile = File.Create(myPath);
myFile.Close();

However, since FileStream implements IDisposable, you can take advantage of the using statement (generally the preferred way of handling a situation like this). This will ensure that the stream is closed and disposed of properly when you're done with it:

using (var myFile = File.Create(myPath))
{
   // interact with myFile here, it will be disposed automatically
}

FileInputStream with InputStreamReader is better than directly using FileReader, because the latter doesn't allow you to specify encoding charset.

Here is an example using BufferedReader, FileInputStream and InputStreamReader together, so that you could read lines from a file.

List<String> words = new ArrayList<>();
List<String> meanings = new ArrayList<>();
public void readAll( ) throws IOException{
    String fileName = "College_Grade4.txt";
    String charset = "UTF-8";
    BufferedReader reader = new BufferedReader(
        new InputStreamReader(
            new FileInputStream(fileName), charset)); 

    String line; 
    while ((line = reader.readLine()) != null) { 
        line = line.trim();
        if( line.length() == 0 ) continue;
        int idx = line.indexOf("\t");
        words.add( line.substring(0, idx ));
        meanings.add( line.substring(idx+1));
    } 
    reader.close();
}

This answer is not strictly related to the question, but you might be interested to find out that this kind of syntax feature is not particular to functions. For example, we can always do something like this:

alert(
    {foo: "I am foo", bar: "I am bar"}.foo
); // alerts "I am foo"

Related to functions. As they are objects, which inherit from Function.prototype, we can do things like:

Function.prototype.foo = function () {
    return function () {
        alert("foo");
    };
};

var bar = (function () {}).foo();

bar(); // alerts foo

And you know, we don't even have to surround functions with parenthesis in order to execute them. Anyway, as long as we try to assign the result to a variable.

var x = function () {} (); // this function is executed but does nothing

function () {} (); // syntax error

One other thing you may do with functions, as soon as you declare them, is to invoke the new operator over them and obtain an object. The following are equivalent:

var obj = new function () {
    this.foo = "bar";
};

var obj = {
    foo : "bar"
};

Did you restart the server after you changed the config file?

Can you telnet to the server from a different machine?

Can you telnet to the server from the server itself?

Instead of

let loginRegisterButton:UIButton = {
//...  }()

Try:

lazy var loginRegisterButton:UIButton = {
//...  }()

That should fix the compile error!!!

The preprocessor inserts the contents of the files A.h and B.h exactly where the include statement occurs (this is really just copy/paste). When the compiler then parses A.cpp, it finds the declaration of class A before it knows about class B. This causes the error you see. There are two ways to solve this:

1. Include B.h in A.h. It is generally a good idea to include header files in the files where they are needed. If you rely on indirect inclusion though another header, or a special order of includes in the compilation unit (cpp-file), this will only confuse you and others as the project gets bigger.

2. If you use member variable of type B in class A, the compiler needs to know the exact and complete declaration of B, because it needs to create the memory-layout for A. If, on the other hand, you were using a pointer or reference to B, then a forward declaration would suffice, because the memory the compiler needs to reserve for a pointer or reference is independent of the class definition. This would look like this:

   class B; // forward declaration        
   class A {
   public:
       A(int id);
   private:
       int _id;
       B & _b;
   };
   

   This is very useful to avoid circular dependencies among headers.

I hope this helps.

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

First time it WILL NOT start "AfterLoading",
It will just register it to start NEXT Load.

private void Main_Load(object sender, System.EventArgs e)
{
    //Register it to Start in Load 
    //Starting from the Next time.
    this.Activated += AfterLoading;
}

private void AfterLoading(object sender, EventArgs e)
{
    this.Activated -= AfterLoading;
    //Write your code here.
}

You should set body and html to position:fixed;, and then set right:, left:, top:, and bottom: to 0;. That way, even if content overflows it will not extend past the limits of the viewport.

For example:

<html>
<body>
    <div id="wrapper"></div>
</body>
</html>

CSS:

html, body, {
    position:fixed;
    top:0;
    bottom:0;
    left:0;
    right:0;
}

Unfortunately to actually see the file you have to select everything on the page and paste it in this tool: http://www.sensefulsolutions.com/2012/01/viewing-chrome-cache-easy-way.html

It is not clear whether you have an instance of the class or the class itself and trying to retrieve the fields, but either way, consider the following code

Using an instance

instance = User.objects.get(username="foo")
instance.__dict__ # returns a dictionary with all fields and their values
instance.__dict__.keys() # returns a dictionary with all fields
list(instance.__dict__.keys()) # returns list with all fields

Using a class

User._meta.__dict__.get("fields") # returns the fields

# to get the field names consider looping over the fields and calling __str__()
for field in User._meta.__dict__.get("fields"):
    field.__str__() # e.g. 'auth.User.id'

File mode, write and binary. Since you are writing a .jpg file, it looks fine.

But if you supposed to read that jpg file you need to use 'rb'

More info

On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files.

Exiting from Java running process is very easy, basically you need to do just two simple things:

1. Call java method System.exit(...) at at application's quit point. For example, if your application is frame based, you can add listener WindowAdapter and and call System.exit(...) inside its method windowClosing(WindowEvent e).

Note: you must call System.exit(...) otherwise your program is error involved.

2. Avoiding unexpected java exceptions to make sure the exit method can be called always. If you add System.exit(...) at right point, but It does not mean that the method can be called always, because unexpected java exceptions may prevent the method from been called.

This is strongly related to your programming skills.

** Following is a simplest sample (JFrame based) which shows you how to call exit method

import java.awt.event.*;
import javax.swing.*;

public class ExitApp extends JFrame
{
   public ExitApp()
   {
      addWindowListener(new WindowAdapter()
      {
         public void windowClosing(WindowEvent e)
         {
           dispose();
           System.exit(0); //calling the method is a must
         }
      });
   }

   public static void main(String[] args)
   {
      ExitApp app=new ExitApp();
      app.setBounds(133,100,532,400);
      app.setVisible(true);
   }
}

In your entity class add @JsonInclude(JsonInclude.Include.NON_NULL) annotation to resolve the problem

I don't like having to change my signature to use the HttpCreateResponse type, so I came up with a little bit of an extended solution to hide that.

public class HttpActionResult : IHttpActionResult
{
    public HttpActionResult(HttpRequestMessage request) : this(request, HttpStatusCode.OK)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code) : this(request, code, null)
    {
    }

    public HttpActionResult(HttpRequestMessage request, HttpStatusCode code, object result)
    {
        Request = request;
        Code = code;
        Result = result;
    }

    public HttpRequestMessage Request { get; }
    public HttpStatusCode Code { get; }
    public object Result { get; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        return Task.FromResult(Request.CreateResponse(Code, Result));
    }
}

You can then add a method to your ApiController (or better your base controller) like this:

protected IHttpActionResult CustomResult(HttpStatusCode code, object data) 
{
    // Request here is the property on the controller.
    return new HttpActionResult(Request, code, data);
}

Then you can return it just like any of the built in methods:

[HttpPost]
public IHttpActionResult Post(Model model)
{
    return model.Id == 1 ?
                Ok() :
                CustomResult(HttpStatusCode.NotAcceptable, new { 
                    data = model, 
                    error = "The ID needs to be 1." 
                });
}

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:

You can also use command line utility net to find information about a Win32 error code. The syntax would be:

What Every Computer Scientist Should Know About Floating-Point Arithmetic

Floating-point numbers cannot represent all the numbers. In particular, 2.51 cannot be represented by a floating-point number, and is represented by a number very close to it:

>>> print "%.16f" % 2.51
2.5099999999999998
>>> 2.51*100
250.99999999999997
>>> 4.02*100
401.99999999999994

If you use int, which truncates the numbers, you get:

250
401

Have a look at the Decimal type.

According to Flexbugs:

In IE 10-11, min-height declarations on flex containers work to size the containers themselves, but their flex item children do not seem to know the size of their parents. They act as if no height has been set at all.

module is a plain JavaScript object with an exports property. exports is a plain JavaScript variable that happens to be set to module.exports. At the end of your file, node.js will basically 'return' module.exports to the require function. A simplified way to view a JS file in Node could be this:

var module = { exports: {} };
var exports = module.exports;

// your code

return module.exports;

If you set a property on exports, like exports.a = 9;, that will set module.exports.a as well because objects are passed around as references in JavaScript, which means that if you set multiple variables to the same object, they are all the same object; so then exports and module.exports are the same object.
But if you set exports to something new, it will no longer be set to module.exports, so exports and module.exports are no longer the same object.

You can build it manually:

var m = new Date();
var dateString = m.getUTCFullYear() +"/"+ (m.getUTCMonth()+1) +"/"+ m.getUTCDate() + " " + m.getUTCHours() + ":" + m.getUTCMinutes() + ":" + m.getUTCSeconds();

and to force two digits on the values that require it, you can use something like this:

("0000" + 5).slice(-2)

Which would look like this:

var m = new Date();_x000D_
var dateString =_x000D_
    m.getUTCFullYear() + "/" +_x000D_
    ("0" + (m.getUTCMonth()+1)).slice(-2) + "/" +_x000D_
    ("0" + m.getUTCDate()).slice(-2) + " " +_x000D_
    ("0" + m.getUTCHours()).slice(-2) + ":" +_x000D_
    ("0" + m.getUTCMinutes()).slice(-2) + ":" +_x000D_
    ("0" + m.getUTCSeconds()).slice(-2);_x000D_
_x000D_
console.log(dateString);

An updated answer here as of 2017, should anyone need it, is that onhashchange is well supported in all major browsers. See caniuse for details. To use it with jQuery no plugin is needed:

$( window ).on( 'hashchange', function( e ) {
    console.log( 'hash changed' );
} );

Occasionally I come across legacy systems where hashbang URL's are still used and this is helpful. If you're building something new and using hash links I highly suggest you consider using the HTML5 pushState API instead.

Pretty late, but you can also do this by annotating a @BeforeStep method:

@BeforeStep
    public void beforeStep(final StepExecution stepExecution) {
        JobParameters parameters = stepExecution.getJobExecution().getJobParameters();
        //use your parameters
}

Include jquery.js and if it is included, load it before any other JavaScript code.

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Working Demo

Strangely, for me it's SubmitChanges as opposed to SaveChanges:

    foreach (var item in w)
    {
        if (Convert.ToInt32(e.CommandArgument) == item.ID)
        {
            item.Sort = 1;
        }
        else
        {
            item.Sort = null;
        }
        db.SubmitChanges();            
    }                   

dat1 and dat2 are Strings in JavaScript. There is no getTime function on the String prototype. I believe you want the Date.parse() function: http://www.w3schools.com/jsref/jsref_parse.asp

You would use it like this:

var date = Date.parse(dat1);

-split outputs an array, and you can save it to a variable like this:

$a = -split 'Once  upon    a     time'
$a[0]

Once

Another cute thing, you can have arrays on both sides of an assignment statement:

$a,$b,$c = -split 'Once  upon    a'
$c

a

Let's say you have a Login action which provides the user with a login screen, then receives the user name and password back after the user submits the form:

public ActionResult Login() {
    return View();
}

public ActionResult Login(string userName, string password) {
    // do login stuff
    return View();
}

MVC isn't being given clear instructions on which action is which, even though we can tell by looking at it. If you add [HttpGet] to the first action and [HttpPost] to the section action, MVC clearly knows which action is which.

Why? See Request Methods. Long and short: When a user views a page, that's a GET request and when a user submits a form, that's usually a POST request. HttpGet and HttpPost just restrict the action to the applicable request type.

[HttpGet]
public ActionResult Login() {
    return View();
}

[HttpPost]
public ActionResult Login(string userName, string password) {
    // do login stuff
    return View();
}

You can also combine the request method attributes if your action serves requests from multiple verbs:

[AcceptVerbs(HttpVerbs.Get | HttpVerbs.Post)].

Instead, try this:

$result = mysql_query("SELECT COUNT(*) AS `count` FROM `Students`");
$row = mysql_fetch_assoc($result);
$count = $row['count'];

Try this code.

Your and should be a && in the where clause.

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
and epl.ArriveAirportBy > sd.UTCArrivalTime

should be

&& epl.ArriveAirportBy > sd.UTCArrivalTime

@hexacyanide's answer is almost a complete one. On Windows command prince could be prince.exe, prince.cmd, prince.bat or just prince (I'm no aware of how gems are bundled, but npm bins come with a sh script and a batch script - npm and npm.cmd). If you want to write a portable script that would run on Unix and Windows, you have to spawn the right executable.

Here is a simple yet portable spawn function:

function spawn(cmd, args, opt) {
    var isWindows = /win/.test(process.platform);

    if ( isWindows ) {
        if ( !args ) args = [];
        args.unshift(cmd);
        args.unshift('/c');
        cmd = process.env.comspec;
    }

    return child_process.spawn(cmd, args, opt);
}

var cmd = spawn("prince", ["-v", "builds/pdf/book.html", "-o", "builds/pdf/book.pdf"])

// Use these props to get execution results:
// cmd.stdin;
// cmd.stdout;
// cmd.stderr;

As mentioned before, [[NSDate date] timeIntervalSince1970] returns an NSTimeInterval, which is a duration in seconds, not milli-seconds.

You can visit https://currentmillis.com/ to see how you can get in the language you desire. Here is the list -

ActionScript    (new Date()).time

WScript.Echo DateDiff("s", "01/01/1970 00:00:00", Now()) * 1000 - offsetInMillis + Timer * 1000 mod 1000

For objective C I did something like below to print it -

long long mills = (long long)([[NSDate date] timeIntervalSince1970] * 1000.0);
 NSLog(@"Current date %lld", mills);

Hopw this helps.

Don't know the nature of your app, but I have seen this error manifested multiple times because of a connection pool leak, so that would be worth checking out. On Linux, socket connections consume file descriptors as well as file system files. Just a thought.

here is how to validate the input to only accept numbers this will accept numbers like 123123123.41212313

<input type="text" 
onkeypress="if ( isNaN(this.value + String.fromCharCode(event.keyCode) )) return false;"
/>

and this will not accept entering the dot (.), so it will only accept integers

<input type="text" 
onkeypress="if ( isNaN( String.fromCharCode(event.keyCode) )) return false;"
/>

this way you will not permit the user to input anything but numbers

There is .center-block class in Twitter Bootstrap 3 (Since v3.0.1), so use:

<img src="..." alt="..." class="img-responsive center-block" />

I don't think Bass's answer is correct. Why touch the row margins? They have a negative margin to offset the column padding for the columns on the edge of the row. Messing with this will break any nested rows.

The answer is simple, just make the container padding equal to the gutter size:

e.g for default bootstrap:

.container {
    padding-left:30px;
    padding-right:30px;
}

Uninstalling(version: 2.19.2) and installing(version: 2.21.0) git client fixed the issue for me.

Which whitespace character? The most common is the normal space, which is between each word in my sentences. This is just " ".

Another way is shown in this CodeProject article:

http://www.codeproject.com/KB/IP/tswindowclipper.aspx

The basic idea is to create a virutal channel that sends the windows position of the app(s) you want to show, then only render that part of the window on the client.

If you want to migrate a #git repository from one server to a new one you can do it like this:

git clone OLD_REPOSITORY_PATH
cd OLD_REPOSITORY_DIR
git remote add NEW_REPOSITORY_ALIAS  NEW_REPOSITORY_PATH
#check out all remote branches 
for remote in `git branch -r | grep -v master `; do git checkout --track $remote ; done
git push --mirror NEW_REPOSITORY_PATH
git push NEW_REPOSITORY_ALIAS --tags

All remote branches and tags from the old repository will be copied to the new repository.

Running this command alone:

git push NEW_REPOSITORY_ALIAS

would only copy a master branch (only tracking branches) to the new repository.

0755 = User:rwx Group:r-x World:r-x

0750 = User:rwx Group:r-x World:--- (i.e. World: no access)

r = read
w = write
x = execute (traverse for directories)

Here is the missing example

library(rjson)
url <- 'http://someurl/data.json'
document <- fromJSON(file=url, method='C')

Shutdown Hooks are unstarted threads that are registered with Runtime.addShutdownHook().JVM does not give any guarantee on the order in which shutdown hooks are started.For more info refer http://techno-terminal.blogspot.in/2015/08/shutdown-hooks.html

Use string.indexOf to get the starting index.

You can do it setting the transparency via style right within the table tag:

<table id="Main table" style="background-color:rgba(0, 0, 0, 0);">

The last digit in the rgba function is for transparency. 1 means 100% opaque, while 0 stands for 100% transparent.

git filter-branch is a powerful command which you can use it to delete a huge file from the commits history. The file will stay for a while and Git will remove it in the next garbage collection. Below is the full process from deleteing files from commit history. For safety, below process runs the commands on a new branch first. If the result is what you needed, then reset it back to the branch you actually want to change.

# Do it in a new testing branch
$ git checkout -b test

# Remove file-name from every commit on the new branch
# --index-filter, rewrite index without checking out
# --cached, remove it from index but not include working tree
# --ignore-unmatch, ignore if files to be removed are absent in a commit
# HEAD, execute the specified command for each commit reached from HEAD by parent link
$ git filter-branch --index-filter 'git rm --cached --ignore-unmatch file-name' HEAD

# The output is OK, reset it to the prior branch master
$ git checkout master
$ git reset --soft test

# Remove test branch
$ git branch -d test

# Push it with force
$ git push --force origin master

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

I used this videocast to set up my GoDaddy domain with Heroku, and it worked perfectly. Very clear and well explained.

Note: Skip the part about CNAME yourdomain.com. (note the .) and the heroku addons:add "custom domains"

http://blog.heroku.com/archives/2009/10/7/heroku_casts_setting_up_custom_domains/

To summarize the video:

1) on GoDaddy and create a CNAME with

Alias Name: www
Host Name: proxy.heroku.com

2) check that your domain has propagated by typing host www.yourdomain.com on the command line

3) run heroku domains:add www.yourdomain.com

4) run heroku domains:add yourdomain.com

It worked for me after these steps. Hope it works for you too!

UPDATE: things have changed, check out this post Heroku/GoDaddy: send naked domain to www

If you need a PEM file without any password you can use this solution.

Just copy and paste the private key and the certificate to the same file and save as .pem.

The file will look like:

-----BEGIN PRIVATE KEY-----
............................
............................
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
...........................
...........................
-----END CERTIFICATE-----

That's the only way I found to upload certificates to Cisco devices for HTTPS.

You can simply use BeginInvokeOnMainThread(). It invokes an Action on the device main (UI) thread.

Device.BeginInvokeOnMainThread(() => { displayToast("text to display"); });

It is simple and works perfectly for me!

EDIT : Works if you're using C# Xamarin

The best time for Kruskal's is O(E logV). For Prim's using fib heaps we can get O(E+V lgV). Therefore on a dense graph, Prim's is much better.

Alternatively you could update brew by installing it again. (Think I did this as El Capitan changed something)

Note: this is a heavy handed approach that will remove all applications installed via brew!

Try to install brew a fresh and it will tell how to uninstall.

The answer with "round-tripping" is not exact : when you do

LocalDateTime ldt = LocalDateTime.ofInstant(instant, ZoneOffset.UTC);

if your system timezone is not UTC/GMT, you change the time !

Full binary tree are a complete binary tree but reverse is not possible, and if the depth of the binary is n the no. of nodes in the full binary tree is ( 2^n-1 ). It is not necessary in the binary tree that it have two child but in the full binary it every node have no or two child.

Your pizza can have exactly three topping types:

• one type of cheese
• one type of meat
• one type of vegetable

So we order two pizzas and choose the following toppings:

Pizza    Topping     Topping Type
-------- ----------  -------------
1        mozzarella  cheese
1        pepperoni   meat
1        olives      vegetable
2        mozzarella  meat
2        sausage     cheese
2        peppers     vegetable

Wait a second, mozzarella can't be both a cheese and a meat! And sausage isn't a cheese!

We need to prevent these sorts of mistakes, to make mozzarella always be cheese. We should use a separate table for this, so we write down that fact in only one place.

Pizza    Topping
-------- ----------
1        mozzarella
1        pepperoni
1        olives
2        mozzarella 
2        sausage
2        peppers

Topping     Topping Type
----------  -------------
mozzarella  cheese
pepperoni   meat
olives      vegetable
sausage     meat
peppers     vegetable

That was the explanation that an 8 year-old might understand. Here is the more technical version.

BCNF acts differently from 3NF only when there are multiple overlapping candidate keys.

The reason is that the functional dependency X -> Y is of course true if Y is a subset of X. So in any table that has only one candidate key and is in 3NF, it is already in BCNF because there is no column (either key or non-key) that is functionally dependent on anything besides that key.

Because each pizza must have exactly one of each topping type, we know that (Pizza, Topping Type) is a candidate key. We also know intuitively that a given topping cannot belong to different types simultaneously. So (Pizza, Topping) must be unique and therefore is also a candidate key. So we have two overlapping candidate keys.

I showed an anomaly where we marked mozarella as the wrong topping type. We know this is wrong, but the rule that makes it wrong is a dependency Topping -> Topping Type which is not a valid dependency for BCNF for this table. It's a dependency on something other than a whole candidate key.

So to solve this, we take Topping Type out of the Pizzas table and make it a non-key attribute in a Toppings table.

In most of the cases, if you are unable to export the certificate as a PFX (including the private key) is because MMC/IIS cannot find/don't have access to the private key (used to generate the CSR). These are the steps I followed to fix this issue:

• Run MMC as Admin
  • Generate the CSR using MMC. Follow this instructions to make the certificate exportable.
• Once you get the certificate from the CA (crt + p7b), import them (Personal\Certificates, and Intermediate Certification Authority\Certificates)
• IMPORTANT: Right-click your new certificate (Personal\Certificates) All Tasks..Manage Private Key, and assign permissions to your account or Everyone (risky!). You can go back to previous permissions once you have finished.
• Now, right-click the certificate and select All Tasks..Export, and you should be able to export the certificate including the private key as a PFX file, and you can upload it to Azure!

Hope this helps!

Using a regex

Using a regex, you can clean everything inside <> :

import re

def cleanhtml(raw_html):
  cleanr = re.compile('<.*?>')
  cleantext = re.sub(cleanr, '', raw_html)
  return cleantext

Some HTML texts can also contain entities that are not enclosed in brackets, such as '&nsbm'. If that is the case, then you might want to write the regex as

cleanr = re.compile('<.*?>|&([a-z0-9]+|#[0-9]{1,6}|#x[0-9a-f]{1,6});')

This link contains more details on this.

Using BeautifulSoup

You could also use BeautifulSoup additional package to find out all the raw text.

You will need to explicitly set a parser when calling BeautifulSoup I recommend "lxml" as mentioned in alternative answers (much more robust than the default one (html.parser) (i.e. available without additional install).

from bs4 import BeautifulSoup
cleantext = BeautifulSoup(raw_html, "lxml").text

But it doesn't prevent you from using external libraries, so I recommend the first solution.

EDIT: To use lxml you need to pip install lxml.

Haven't seen this solution yet so here's how I did it without using read_csv:

df.rename(columns={'A':'','B':''})

If you rename all your column names to empty strings your table will return without a header.

And if you have a lot of columns in your table you can just create a dictionary first instead of renaming manually:

df_dict = dict.fromkeys(df.columns, '')
df.rename(columns = df_dict)

This my program in ruby . It will return arrays, each holding the subsequences summing to the provided target value.

array = [1, 3, 4, 2, 7, 8, 9]

0..array.size.times.each do |i| 
  array.combination(i).to_a.each { |a| print a if a.inject(:+) == 9} 
end

A solution with flexbox (working on IE11): (or view on jsfiddle)

<html>
  <style>
    html, body {
      height: 100%; /* fix for IE11, not needed for chrome/ff */
      margin: 0; /* CSS-reset for chrome */
    }
  </style>
  <body style="display: flex;">
    <div style="background-color: black; flex: 1; margin: 25px;"></div>
  </body>
</html>

(The CSS-reset is not necessarily important for the actual problem.)

The important part is flex: 1 (In combination with display: flex at the parent). Funnily enough, the most plausible explanation I know for how the Flex property works comes from a react-native documentation, so I refer to it anyway:

(...) flex: 1, which tells a component to fill all available space, shared evenly amongst other components with the same parent

it is better to use json after post your resuest like below

  var clien = new RestClient("https://smple.com/");
  var request = new RestRequest("index", Method.POST);
  request.AddHeader("Sign", signinstance);    
  request.AddJsonBody(JsonConvert.SerializeObject(yourclass));
  var response = client.Execute<YourReturnclassSample>(request);
  if (response.StatusCode == System.Net.HttpStatusCode.Created)
   {
       return Ok(response.Content);
   }

Can you not use like this?

@Query("SELECT DISTINCT name FROM people p (nolock) WHERE p.name NOT IN (:myparam)")
List<String> findNonReferencedNames(@Param("myparam")List<String> names);

P.S. I write queries in SQL Server 2012 a lot and using nolock in server is a good practice, you can ignore nolock if a local db is used.

Seems like your db name is not being mapped correctly (after you've updated your question)

One case which hasn't been covered is how to handle cancellation inside of an async method. Take for example a simple case where you need to upload some data to a service get it to calculate something and then return some results.

public async Task<Results> ProcessDataAsync(MyData data)
{
    var client = await GetClientAsync();
    await client.UploadDataAsync(data);
    await client.CalculateAsync();
    return await client.GetResultsAsync();
}

If you want to support cancellation then the easiest way would be to pass in a token and check if it has been cancelled between each async method call (or using ContinueWith). If they are very long running calls though you could be waiting a while to cancel. I created a little helper method to instead fail as soon as canceled.

public static class TaskExtensions
{
    public static async Task<T> WaitOrCancel<T>(this Task<T> task, CancellationToken token)
    {
        token.ThrowIfCancellationRequested();
        await Task.WhenAny(task, token.WhenCanceled());
        token.ThrowIfCancellationRequested();

        return await task;
    }

    public static Task WhenCanceled(this CancellationToken cancellationToken)
    {
        var tcs = new TaskCompletionSource<bool>();
        cancellationToken.Register(s => ((TaskCompletionSource<bool>)s).SetResult(true), tcs);
        return tcs.Task;
    }
}

So to use it then just add .WaitOrCancel(token) to any async call:

public async Task<Results> ProcessDataAsync(MyData data, CancellationToken token)
{
    Client client;
    try
    {
        client = await GetClientAsync().WaitOrCancel(token);
        await client.UploadDataAsync(data).WaitOrCancel(token);
        await client.CalculateAsync().WaitOrCancel(token);
        return await client.GetResultsAsync().WaitOrCancel(token);
    }
    catch (OperationCanceledException)
    {
        if (client != null)
            await client.CancelAsync();
        throw;
    }
}

Note that this will not stop the Task you were waiting for and it will continue running. You'll need to use a different mechanism to stop it, such as the CancelAsync call in the example, or better yet pass in the same CancellationToken to the Task so that it can handle the cancellation eventually. Trying to abort the thread isn't recommended.

You may simply want a UNIQUE CONSTRAINT. Especially if you already have a surrogate key. (example of an already existing surrogate key would be a single column that is an AUTO_INCREMENT )

Below is the sql code for a Unique Constraint

ALTER TABLE `MyDatabase`.`Provider`
    ADD CONSTRAINT CK_Per_Place_Thing_Unique UNIQUE (person,place,thing)
;

As Andrie said, system.time() works fine. For short function I prefer to put replicate() in it:

system.time( replicate(10000, myfunction(with,arguments) ) )

I used the System.Xml.Linq.XElement for the purpose. Just check code below for reading the value of first child node of the xml(not the root node).

        string textXml = "<xmlroot><firstchild>value of first child</firstchild>........</xmlroot>";
        XElement xmlroot = XElement.Parse(textXml);
        string firstNodeContent = ((System.Xml.Linq.XElement)(xmlroot.FirstNode)).Value;

import argparse
parser = argparse.ArgumentParser()
parser.add_argument('--example', nargs='?', const=1, type=int)
args = parser.parse_args()
print(args)

% test.py 
Namespace(example=None)
% test.py --example
Namespace(example=1)
% test.py --example 2
Namespace(example=2)

• nargs='?' means 0-or-1 arguments
• const=1 sets the default when there are 0 arguments
• type=int converts the argument to int

If you want test.py to set example to 1 even if no --example is specified, then include default=1. That is, with

parser.add_argument('--example', nargs='?', const=1, type=int, default=1)

then

% test.py 
Namespace(example=1)

This solution might also help :

$(document).ready(function () {
    $(window).resize(function() {
        if ($(window).width() < 600) {
            $('body').css('font-size', '2.8vw' );
        } else if ($(window).width() >= 600 && $(window).width() < 750) {
            $('body').css('font-size', '2.4vw');
        } 
         // and so on... (according to our needs)
        } else if ($(window).width() >= 1200) {
            $('body').css('font-size', '1.2vw');
        }
    }); 
  });

It worked for me well !

You're missing a required space between the bracket and -e:

#!/bin/bash
if [ -e x.txt ]
then
    echo "ok"
else
    echo "nok"
fi

print(', '.join(names))

This, like it sounds, just takes all the elements of the list and joins them with ', '.

Your best bet is to change that column to a timestamp. MySQL will automatically use the first timestamp in a row as a 'last modified' value and update it for you. This is configurable if you just want to save creation time.

See doc http://dev.mysql.com/doc/refman/5.7/en/timestamp-initialization.html

With ES6 you can write this:

const countries = ['United States', 'Canada', 'Argentina', 'Armenia'];

const $ul = $('<ul>', { class: "mylist" }).append(
  countries.map(country => 
    $("<li>").append($("<a>").text(country))
  )
);

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.

Some keypoints will be:

1. InnoDB does ACID-compliant transaction. http://en.wikipedia.org/wiki/ACID
2. InnoDB does Referential Integrity (foreign key relations) http://www.w3resource.com/sql/joins/joining-tables-through-referential-integrity.php
3. MyIsam does full text search, InnoDB doesn't
4. I have been told InnoDB is faster on executing writes but slower than MyISAM doing reads (I cannot back this up and could not find any article that analyses this, I do however have the guy that told me this in high regard), feel free to ignore this point or do your own research.
5. Default configuration does not work very well for InnoDB needs to be tweaked accordingly, run a tool like http://mysqltuner.pl/mysqltuner.pl to help you.

Notes:

• In my opinion the second point is probably the one were InnoDB has a huge advantage over MyISAM.
• Full text search not working with InnoDB is a bit of a pain, You can mix different storage engines but be careful when doing so.

Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.

The res.json() function should be sufficient for most cases.

app.get('/', (req, res) => res.json({ answer: 42 }));

The res.json() function converts the parameter you pass to JSON using JSON.stringify() and sets the Content-Type header to application/json; charset=utf-8 so HTTP clients know to automatically parse the response.

If you get that error message (Peer authentication failed for user (PG::Error)) when running unit tests, make sure the test database exists.
