It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)

Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.

Even though this is not really using RegExp to get the job done - or maybe because of that - this looks like a nice solution to me: https://intl-tel-input.com/node_modules/intl-tel-input/examples/gen/is-valid-number.html

The error TypeError: 'numpy.ndarray' object is not callable means that you tried to call a numpy array as a function. We can reproduce the error like so in the repl:

In [16]: import numpy as np

In [17]: np.array([1,2,3])()
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-17-1abf8f3c8162> in <module>()
----> 1 np.array([1,2,3])()

TypeError: 'numpy.ndarray' object is not callable

If we are to assume that the error is indeed coming from the snippet of code that you posted (something that you should check,) then you must have reassigned either pd.rolling_mean or pd.rolling_std to a numpy array earlier in your code.

What I mean is something like this:

In [1]: import numpy as np

In [2]: import pandas as pd

In [3]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Works
Out[3]: array([ nan,  nan,  nan])

In [4]: pd.rolling_mean = np.array([1,2,3])

In [5]: pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
/home/user/<ipython-input-5-f528129299b9> in <module>()
----> 1 pd.rolling_mean(np.array([1,2,3]), 20, min_periods=5) # Doesn't work anymore...

TypeError: 'numpy.ndarray' object is not callable

So, basically you need to search the rest of your codebase for pd.rolling_mean = ... and/or pd.rolling_std = ... to see where you may have overwritten them.

As in the answer of Escobar Ceaser, I suggest to use quotes arround the whole path. It's the common way to wrap the whole path in "", not only separate directory names within the path.

I had a similar issue that it didn't work for me. But it was no option to use "" within the path for separate directory names because the path contained environment variables, which theirself cover more than one directory hierarchies. The conclusion was that I missed the space between the closing " and the (

The correct version, with the space before the bracket, would be

If NOT exist "C:\Documents and Settings\John\Start Menu\Programs\Software Folder" (
 start "\\filer\repo\lab\software\myapp\setup.exe"
 pause
) 

If you need async: false in your ajax, you should use success instead of .done. Else you better to use .done. This is from jQuery official site:

As of jQuery 1.8, the use of async: false with jqXHR ($.Deferred) is deprecated; you must use the success/error/complete callback options instead of the corresponding methods of the jqXHR object such as jqXHR.done().

First off, it might not be good to just go by recall alone. You can simply achieve a recall of 100% by classifying everything as the positive class. I usually suggest using AUC for selecting parameters, and then finding a threshold for the operating point (say a given precision level) that you are interested in.

For how class_weight works: It penalizes mistakes in samples of class[i] with class_weight[i] instead of 1. So higher class-weight means you want to put more emphasis on a class. From what you say it seems class 0 is 19 times more frequent than class 1. So you should increase the class_weight of class 1 relative to class 0, say {0:.1, 1:.9}. If the class_weight doesn't sum to 1, it will basically change the regularization parameter.

For how class_weight="auto" works, you can have a look at this discussion. In the dev version you can use class_weight="balanced", which is easier to understand: it basically means replicating the smaller class until you have as many samples as in the larger one, but in an implicit way.

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

The biggest problem that i have after enabling the Push Notification from Capabilities and remaking all the certificates is that the Target name and the folder name where was stored the project was composed from 2 strings separated by space. After removing the space all worked just fine!

If you guys are having null with every attempt to get a view with any int position, try to add a new constructor parameter to your adapter like this for example:

class RecyclerViewTableroAdapter(
private val fichas: Array<MFicha?>,
private val activity: View.OnClickListener,
private val indicesGanadores:MutableList<Int>
) : RecyclerView.Adapter<RecyclerViewTableroAdapter.ViewHolder>() {
//CODE 
}

I added indicesGanadores to color my cardview background if my game is won.

override fun onBindViewHolder(holder: ViewHolder, position: Int) {
//CODE
if(indicesGanadores.contains(position)){
        holder.cardViewFicha.setCardBackgroundColor((activity as MainActivity).resources.getColor(R.color.DarkGreen))
    }
//MORE CODE
}  

If I don't have to color my background yet I just send an empty mutable list like this:

binding.recyclerViewMain.adapter = RecyclerViewTableroAdapter(fichasTablero, this@MainActivity, mutableListOf<Int>())

Happy coding!...

I had same issue, was due to multiple copies of ssl.conf In /etc/httpd/conf.d - There should only be one.

If you want to have unique elements in your list, then why not use a set, if of course, order does not matter for you: -

>>> s = set()
>>> s.add(2)
>>> s.add(4)
>>> s.add(5)
>>> s.add(2)
>>> s
39: set([2, 4, 5])

If order is a matter of concern, then you can use: -

>>> def addUnique(l, num):
...     if num not in l:
...         l.append(num)
...     
...     return l

You can also find an OrderedSet recipe, which is referred to in Python Documentation

Python 3's range type works just like Python 2's xrange. I'm not sure why you're seeing a slowdown, since the iterator returned by your xrange function is exactly what you'd get if you iterated over range directly.

I'm not able to reproduce the slowdown on my system. Here's how I tested:

Python 2, with xrange:

Python 2.7.3 (default, Apr 10 2012, 23:24:47) [MSC v.1500 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> timeit.timeit("[x for x in xrange(1000000) if x%4]",number=100)
18.631936646865853

Python 3, with range is a tiny bit faster:

Python 3.3.0 (v3.3.0:bd8afb90ebf2, Sep 29 2012, 10:57:17) [MSC v.1600 64 bit (AMD64)] on win32
Type "copyright", "credits" or "license()" for more information.
>>> import timeit
>>> timeit.timeit("[x for x in range(1000000) if x%4]",number=100)
17.31399508687869

I recently learned that Python 3's range type has some other neat features, such as support for slicing: range(10,100,2)[5:25:5] is range(20, 60, 10)!

Small addition to all of above:

Better use map, when you need to get elements by range, as they are sorted and you can just iterate over them from one boundary to another.

Just you need to desc with asc. Write the query like below. It will return the values in ascending order.

SELECT * FROM table GROUP BY m_id ORDER BY m_id asc;

Here’s an example defines a SimpleDateFormat object as a static field. When two or more threads access “someMethod” concurrently with different dates, they can mess with each other’s results.

    public class SimpleDateFormatExample {
         private static final SimpleDateFormat simpleFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

         public String someMethod(Date date) {
            return simpleFormat.format(date);
         }
    }

You can create a service like below and use jmeter to simulate concurrent users using the same SimpleDateFormat object formatting different dates and their results will be messed up.

public class FormattedTimeHandler extends AbstractHandler {

private static final String OUTPUT_TIME_FORMAT = "yyyy-MM-dd HH:mm:ss.SSS";
private static final String INPUT_TIME_FORMAT = "yyyy-MM-ddHH:mm:ss";
private static final SimpleDateFormat simpleFormat = new SimpleDateFormat(OUTPUT_TIME_FORMAT);
// apache commons lang3 FastDateFormat is threadsafe
private static final FastDateFormat fastFormat = FastDateFormat.getInstance(OUTPUT_TIME_FORMAT);

public void handle(String target, Request baseRequest, HttpServletRequest request, HttpServletResponse response)
        throws IOException, ServletException {

    response.setContentType("text/html;charset=utf-8");
    response.setStatus(HttpServletResponse.SC_OK);
    baseRequest.setHandled(true);

    final String inputTime = request.getParameter("time");
    Date date = LocalDateTime.parse(inputTime, DateTimeFormat.forPattern(INPUT_TIME_FORMAT)).toDate();

    final String method = request.getParameter("method");
    if ("SimpleDateFormat".equalsIgnoreCase(method)) {
        // use SimpleDateFormat as a static constant field, not thread safe
        response.getWriter().println(simpleFormat.format(date));
    } else if ("FastDateFormat".equalsIgnoreCase(method)) {
        // use apache commons lang3 FastDateFormat, thread safe
        response.getWriter().println(fastFormat.format(date));
    } else {
        // create new SimpleDateFormat instance when formatting date, thread safe
        response.getWriter().println(new SimpleDateFormat(OUTPUT_TIME_FORMAT).format(date));
    }
}

public static void main(String[] args) throws Exception {
    // embedded jetty configuration, running on port 8090. change it as needed.
    Server server = new Server(8090);
    server.setHandler(new FormattedTimeHandler());

    server.start();
    server.join();
}

}

Usually for normal transition we use,

let next:SecondViewController = SecondViewController()
self.presentViewController(next, animated: true, completion: nil)

But sometimes when using navigation controller, you might face a black screen. In that case, you need to use like,

let next:ThirdViewController = storyboard?.instantiateViewControllerWithIdentifier("ThirdViewController") as! ThirdViewController
self.navigationController?.pushViewController(next, animated: true)

Moreover none of the above solution preserves navigationbar when you call from storyboard or single xib to another xib. If you use nav bar and want to preserve it just like normal push, you have to use,

Let's say, "MyViewController" is identifier for MyViewController

let viewController = MyViewController(nibName: "MyViewController", bundle: nil)
self.navigationController?.pushViewController(viewController, animated: true)

SQL Server (2005, 2000, 7.0) does not have any flexible, or even non-flexible, way of taking an arbitrarily structured datetime in string format and converting it to the datetime data type.

By "arbitrarily", I mean "a form that the person who wrote it, though perhaps not you or I or someone on the other side of the planet, would consider to be intuitive and completely obvious." Frankly, I'm not sure there is any such algorithm.

The following worked for me to vertically align content (multi-line) in a list-table

Using theme overrides .css option I defined:

.stub {

In the theme that I use 'python-docs-theme', the cell entry is defined as 'stub' class. Use your browser development menu to inspect what your theme class is for cell content and update that accordingly.

I've been searching for a way to save notebooks as html, since whenever I try to download as html with my new Jupyter installation, I always get a 500 : Internal Server Error The error was: nbconvert failed: validate() got an unexpected keyword argument 'relax_add_props' error. Oddly enough, I've found that downloading as html is as simple as:

1. Left click in the notebook
2. Click 'Save As...' in the dropdown menu
3. Save accordingly

No print preview, no print, no nbconvert. Using Jupyter Version: 1.0.0. Just a suggestion to try (obviously not all setups are the same).

The accepted answer does not preserve STDERR as a separate file descriptor. That means

./script.sh >/dev/null

will not output bar to the terminal, only to the logfile, and

./script.sh 2>/dev/null

will output both foo and bar to the terminal. Clearly that's not the behaviour a normal user is likely to expect. This can be fixed by using two separate tee processes both appending to the same log file:

#!/bin/bash

# See (and upvote) the comment by JamesThomasMoon1979 
# explaining the use of the -i option to tee.
exec >  >(tee -ia foo.log)
exec 2> >(tee -ia foo.log >&2)

echo "foo"
echo "bar" >&2

(Note that the above does not initially truncate the log file - if you want that behaviour you should add

>foo.log

to the top of the script.)

The POSIX.1-2008 specification of tee(1) requires that output is unbuffered, i.e. not even line-buffered, so in this case it is possible that STDOUT and STDERR could end up on the same line of foo.log; however that could also happen on the terminal, so the log file will be a faithful reflection of what could be seen on the terminal, if not an exact mirror of it. If you want the STDOUT lines cleanly separated from the STDERR lines, consider using two log files, possibly with date stamp prefixes on each line to allow chronological reassembly later on.

For those who are looking for the shortest possible "item renderer" solution from a partial, so a combo of ng-repeat and ng-include:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'" />

Actually, if you use it like this for one repeater, it will work, but won't for 2 of them! Angular (v1.2.16) will freak out for some reason if you have 2 of these one after another, so it is safer to close the div the pre-xhtml way:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'"></div>

(PartlyStolen from ServerFault)

I think that both are functionally the same, but they simply have different authors, and the one is simply named more appropriately than the other.

Here is a quick backgrounder in naming conventions (for those unfamiliar), which explains the frustration by the question asker: For many *nix applications, the piece that does the backend work is called a "daemon" (think "service" in Windows-land), while the interface or client application is what you use to control or access the daemon. The daemon is most often named the same as the client, with the letter "d" appended to it. For example "imap" would be a client that connects to the "imapd" daemon.

This naming convention is clearly being adhered to by memcache when you read the introduction to the memcache module (notice the distinction between memcache and memcached in this excerpt):

Memcache module provides handy procedural and object oriented interface to memcached, highly effective caching daemon, which was especially designed to decrease database load in dynamic web applications.

The Memcache module also provides a session handler (memcache).

More information about memcached can be found at » http://www.danga.com/memcached/.

The frustration here is caused by the author of the PHP extension which was badly named memcached, since it shares the same name as the actual daemon called memcached. Notice also that in the introduction to memcached (the php module), it makes mention of libmemcached, which is the shared library (or API) that is used by the module to access the memcached daemon:

memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.

This extension uses libmemcached library to provide API for communicating with memcached servers. It also provides a session handler (memcached).

Information about libmemcached can be found at » http://tangent.org/552/libmemcached.html.

If this is a programming question, then I would suggest you write your own regular expression to parse all the retrieved contents. Target tags are IMG and A for standard HTML. For JAVA,

final String openingTags = "(<a [^>]*href=['\"]?|<img[^> ]* src=['\"]?)";

this along with Pattern and Matcher classes should detect the beginning of the tags. Add LINK tag if you also want CSS.

However, it is not as easy as you may have intially thought. Many web pages are not well-formed. Extracting all the links programmatically that human being can "recognize" is really difficult if you need to take into account all the irregular expressions.

Good luck!

The other answers will break if output of command contains spaces (which is rather frequent) or glob characters like *, ?, [...].

To get the output of a command in an array, with one line per element, there are essentially 3 ways:

1. With Bash=4 use mapfile—it's the most efficient:

   mapfile -t my_array < <( my_command )
   

2. Otherwise, a loop reading the output (slower, but safe):

   my_array=()
   while IFS= read -r line; do
       my_array+=( "$line" )
   done < <( my_command )
   

3. As suggested by Charles Duffy in the comments (thanks!), the following might perform better than the loop method in number 2:

   IFS=$'\n' read -r -d '' -a my_array < <( my_command && printf '\0' )
   

   Please make sure you use exactly this form, i.e., make sure you have the following:

   • IFS=$'\n' on the same line as the read statement: this will only set the environment variable IFS for the read statement only. So it won't affect the rest of your script at all. The purpose of this variable is to tell read to break the stream at the EOL character \n.
   • -r: this is important. It tells read to not interpret the backslashes as escape sequences.
   • -d '': please note the space between the -d option and its argument ''. If you don't leave a space here, the '' will never be seen, as it will disappear in the quote removal step when Bash parses the statement. This tells read to stop reading at the nil byte. Some people write it as -d $'\0', but it is not really necessary. -d '' is better.
   • -a my_array tells read to populate the array my_array while reading the stream.
   • You must use the printf '\0' statement after my_command, so that read returns 0; it's actually not a big deal if you don't (you'll just get an return code 1, which is okay if you don't use set -e – which you shouldn't anyway), but just bear that in mind. It's cleaner and more semantically correct. Note that this is different from printf '', which doesn't output anything. printf '\0' prints a null byte, needed by read to happily stop reading there (remember the -d '' option?).

If you can, i.e., if you're sure your code will run on Bash=4, use the first method. And you can see it's shorter too.

If you want to use read, the loop (method 2) might have an advantage over method 3 if you want to do some processing as the lines are read: you have direct access to it (via the $line variable in the example I gave), and you also have access to the lines already read (via the array ${my_array[@]} in the example I gave).

Note that mapfile provides a way to have a callback eval'd on each line read, and in fact you can even tell it to only call this callback every N lines read; have a look at help mapfile and the options -C and -c therein. (My opinion about this is that it's a little bit clunky, but can be used sometimes if you only have simple things to do — I don't really understand why this was even implemented in the first place!).

Now I'm going to tell you why the following method:

my_array=( $( my_command) )

is broken when there are spaces:

$ # I'm using this command to test:
$ echo "one two"; echo "three four"
one two
three four
$ # Now I'm going to use the broken method:
$ my_array=( $( echo "one two"; echo "three four" ) )
$ declare -p my_array
declare -a my_array='([0]="one" [1]="two" [2]="three" [3]="four")'
$ # As you can see, the fields are not the lines
$
$ # Now look at the correct method:
$ mapfile -t my_array < <(echo "one two"; echo "three four")
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # Good!

Then some people will then recommend using IFS=$'\n' to fix it:

$ IFS=$'\n'
$ my_array=( $(echo "one two"; echo "three four") )
$ declare -p my_array
declare -a my_array='([0]="one two" [1]="three four")'
$ # It works!

But now let's use another command, with globs:

$ echo "* one two"; echo "[three four]"
* one two
[three four]
$ IFS=$'\n'
$ my_array=( $(echo "* one two"; echo "[three four]") )
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="t")'
$ # What?

That's because I have a file called t in the current directory… and this filename is matched by the glob [three four]… at this point some people would recommend using set -f to disable globbing: but look at it: you have to change IFS and use set -f to be able to fix a broken technique (and you're not even fixing it really)! when doing that we're really fighting against the shell, not working with the shell.

$ mapfile -t my_array < <( echo "* one two"; echo "[three four]")
$ declare -p my_array
declare -a my_array='([0]="* one two" [1]="[three four]")'

here we're working with the shell!

To link to a UNC path from an HTML document, use file:///// (yes, that's five slashes).

file://///server/path/to/file.txt

Note that this is most useful in IE and Outlook/Word. It won't work in Chrome or Firefox, intentionally - the link will fail silently. Some words from the Mozilla team:

For security purposes, Mozilla applications block links to local files (and directories) from remote files.

And less directly, from Google:

Firefox and Chrome doesn't open "file://" links from pages that originated from outside the local machine. This is a design decision made by those browsers to improve security.

The Mozilla article includes a set of client settings you can use to override this behavior in Firefox, and there are extensions for both browsers to override this restriction.

You have defined 5 fields in your control file. Your fields are terminated by a comma, so you need 5 commas in each record for the 5 fields unless TRAILING NULLCOLS is specified, even though you are loading the ID field with a sequence value via the SQL String.

RE: Comment by OP

That's not my experience with a brief test. With the following control file:

load data
infile *
into table T_new
fields terminated by "," optionally enclosed by '"'
( A,
  B,
  C,
  D,
  ID "ID_SEQ.NEXTVAL"
)

Note that the only row that loaded correctly had 5 commas. Even the 3rd row, with all data values present except ID, the data does not load. Unless I'm missing something...

You can use an extension method.

static class Extensions
{
    public static IList<T> Clone<T>(this IList<T> listToClone) where T: ICloneable

    }
}

A nuanced variant of some of the answers here that answers the OP's question:

git archive [email protected]:foo/bar.git \
  HEAD path/to/file.txt | tar -xO path/to/file.txt > file.txt

I figured it this way:

* { padding: 0; margin: 0 }
body { height: 100%; white-space: nowrap }
html { height: 100% }

.red { background: red }
.blue { background: blue }
.yellow { background: yellow }

.header { width: 100%; height: 10%; position: fixed }
.wrapper { width: 1000%; height: 100%; background: green }
.page { width: 10%; height: 100%; float: left }

<div class="header red"></div>
<div class="wrapper">
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>
    <div class="page yellow"></div>
    <div class="page blue"></div>

I have the wrapper at 1000% and ten pages at 10% each. I set mine up to still have "pages" with each being 100% of the window (color coded). You can do eight pages with an 800% wrapper. I guess you can leave out the colors and have on continues page. I also set up a fixed header, but that's not necessary. Hope this helps.

I was able to do this by calling the DefaultIfEmpty() on the main model. This allowed me to left join on lazy loaded entities, seems more readable to me:

        var complaints = db.Complaints.DefaultIfEmpty()
            .Where(x => x.DateStage1Complete == null || x.DateStage2Complete == null)
            .OrderBy(x => x.DateEntered)
            .Select(x => new
            {
                ComplaintID = x.ComplaintID,
                CustomerName = x.Customer.Name,
                CustomerAddress = x.Customer.Address,
                MemberName = x.Member != null ? x.Member.Name: string.Empty,
                AllocationName = x.Allocation != null ? x.Allocation.Name: string.Empty,
                CategoryName = x.Category != null ? x.Category.Ssl_Name : string.Empty,
                Stage1Start = x.Stage1StartDate,
                Stage1Expiry = x.Stage1_ExpiryDate,
                Stage2Start = x.Stage2StartDate,
                Stage2Expiry = x.Stage2_ExpiryDate
            });

Here is one command that displays the number of threads of a given process :

ps -L -o pid= -p <pid> | wc -l

Unlike the other ps based answers, there is here no need to substract 1 from its output as there is no ps header line thanks to the -o pid=option.

I tried to avoid too much custom CSS and after reading some other examples I merged the ideas there and got this solution:

<div class="form-group has-feedback has-clear">
    <input type="text" class="form-control" ng-model="ctrl.searchService.searchTerm" ng-change="ctrl.search()" placeholder="Suche"/>
    <a class="glyphicon glyphicon-remove-sign form-control-feedback form-control-clear" ng-click="ctrl.clearSearch()" style="pointer-events: auto; text-decoration: none;cursor: pointer;"></a>
</div>

As I don't use bootstrap's JavaScript, just the CSS together with Angular, I don't need the classes has-clear and form-control-clear, and I implemented the clear function in my AngularJS controller. With bootstrap's JavaScript this might be possible without own JavaScript.

Here's how I did it. If there is a smoother way, please please tell me.

Inside the <a> tags where the links for the menu are I added this code:

onclick="$('.navbar-toggle').click()"

It preserves the slide animation. So in full use it would look like this:

<nav class="navbar navbar-inverse navbar-fixed-top" role="navigation" ng-controller="topNavController as topNav">
<div class="container">
    <div class="navbar-header">
        <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
            <span class="sr-only">Toggle navigation</span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </button>
        <a class="navbar-brand" href="home.html">My Cool Site</a>
    </div>
    <div id="navbar" class="navbar-collapse collapse">
        <ul class="nav navbar-nav">
            <li class="active" onclick="$('.navbar-toggle').click()"><a href="home.html" onclick="$('.navbar-toggle').click()"><i class="fa fa-home"></i> Home</a></li>
            <li><a href="aboutus.html" onclick="$('.navbar-toggle').click()">About Us</a></li>
        </ul>
    </div><!--/.nav-collapse -->
</div>

The device I tested at had wrong time set. So when I tried accessing a page with a certificate that would run out soon it would deny access because the device though the certificate had expired. To fix, set proper time on the device!

A shared service is the best approach

export class SharedService {
  globalVar:string;
}

But you need to be very careful when registering it to be able to share a single instance for whole your application. You need to define it when registering your application:

bootstrap(AppComponent, [SharedService]);

But not to define it again within the providers attributes of your components:

@Component({
  (...)
  providers: [ SharedService ], // No
  (...)
})

Otherwise a new instance of your service will be created for the component and its sub-components.

You can have a look at this question regarding how dependency injection and hierarchical injectors work in Angular 2:

• What's the best way to inject one service into another in angular 2 (Beta)?

You should notice that you can also define Observable properties in the service to notify parts of your application when your global properties change:

export class SharedService {
  globalVar:string;
  globalVarUpdate:Observable<string>;
  globalVarObserver:Observer;

  constructor() {
    this.globalVarUpdate = Observable.create((observer:Observer) => {
      this.globalVarObserver = observer;
    });
  }

  updateGlobalVar(newValue:string) {
    this.globalVar = newValue;
    this.globalVarObserver.next(this.globalVar);
  }
}

See this question for more details:

inet_ntoa() converts a in_addr to string:

The inet_ntoa function converts an (Ipv4) Internet network address into an ASCII string in Internet standard dotted-decimal format.

inet_addr() does the reverse job

The inet_addr function converts a string containing an IPv4 dotted-decimal address into a proper address for the IN_ADDR structure

PS this the first result googling "in_addr to string"!

An example:

log4j.rootLogger=ERROR, logfile

log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
log4j.appender.logfile.datePattern='-'dd'.log'
log4j.appender.logfile.File=log/radius-prod.log
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
log4j.appender.logfile.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

log4j.logger.foo.bar.Baz=DEBUG, myappender
log4j.additivity.foo.bar.Baz=false

log4j.appender.myappender=org.apache.log4j.DailyRollingFileAppender
log4j.appender.myappender.datePattern='-'dd'.log'
log4j.appender.myappender.File=log/access-ext-dmz-prod.log
log4j.appender.myappender.layout=org.apache.log4j.PatternLayout
log4j.appender.myappender.layout.ConversionPattern=%-6r %d{ISO8601} %-5p %40.40c %x - %m\n

Is this a problem Only when you run ant -d or ant -verbose, but works other times?

I noticed this error message line:

Could not load definitions from resource org/apache/tools/ant/antlib.xml. It could not be found.

The org/apache/tools/ant/antlib.xml file is embedded in the ant.jar. The ant command is really a shell script called ant or a batch script called ant.bat. If the environment variable ANT_HOME is not set, it will figure out where it's located by looking to see where the ant command itself is located.

Sometimes I've seen this where someone will move the ant shell/batch script to put it in their path, and have ANT_HOME either not set, or set incorrectly.

What platform are you on? Is this Windows or Unix/Linux/MacOS? If you're on Windows, check to see if %ANT_HOME% is set. If it is, make sure it's the right directory. Make sure you have set your PATH to include %ANT_HOME%/bin.

If you're on Unix, don't copy the ant shell script to an executable directory. Instead, make a symbolic link. I have a directory called /usr/local/bin where I put the command I want to override the commands in /bin and /usr/bin. My Ant is installed in /opt/ant-1.9.2, and I have a symbolic link from /opt/ant-1.9.2 to /opt/ant. Then, I have symbolic links from all commands in /opt/ant/bin to /usr/local/bin. The Ant shell script can detect the symbolic links and find the correct Ant HOME location.

Next, go to your Ant installation directory and look under the lib directory to make sure ant.jar is there, and that it contains org/apache/tools/ant/antlib.xml. You can use the jar tvf ant.jar command. The only thing I can emphasize is that you do have everything setup correctly. You have your Ant shell script in your PATH either because you included the bin directory of your Ant's HOME directory in your classpath, or (if you're on Unix/Linux/MacOS), you have that file symbolically linked to a directory in your PATH.

Make sure your JAVA_HOME is set correctly (on Unix, you can use the symbolic link trick to have the java command set it for you), and that you're using Java 1.5 or higher. Java 1.4 will no longer work with newer versions of Ant.

Also run ant -version and see what you get. You might get the same error as before which leads me to think you have something wrong.

Let me know what you find, and your OS, and I can give you directions on reinstalling Ant.

Note that if you have committed a bunch of changes in various submodules, you can (or will be soon able to) push everything in one go (ie one push from the parent repo), with:

git push --recurse-submodules=on-demand

git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

--recurse-submodules=<check|on-demand|no>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

or another handy way:

_.omit(arr, _.findWhere(arr, {id: 3}));

my 2 cents

You need to add the column with a default of null, then alter the column to have default now().

ALTER TABLE mytable ADD COLUMN created_at TIMESTAMP;
ALTER TABLE mytable ALTER COLUMN created_at SET DEFAULT now();

After adding files to the stage, you need to commit them with git commit -m "comment" after git add .. Finally, to push them to a remote repository, you need to git push <remote_repo> <local_branch>.

Inline SVG can be used in IE 10 and 11 and Edge 12.

I've created a project called gray which includes a polyfill for these browsers. The polyfill switches out <img> tags with inline SVG: https://github.com/karlhorky/gray

To implement, the short version is to download the jQuery plugin at the GitHub link above and add after jQuery at the end of your body:

<script src="/js/jquery.gray.min.js"></script>

Then every image with the class grayscale will appear as gray.

<img src="/img/color.jpg" class="grayscale">

You can see a demo too if you like.

Make sure you have a service started and listening on the port.

netstat -ln | grep 8080

and

sudo netstat -tulpn

Our DMS Software Reengineering Toolkit has static control/dataflow/points-to/call graph analysis that has been applied to huge systems (~~25 million lines) of C code, and produced such call graphs, including functions called via function pointers.

This works fine for me using MySQL 5.1.35:

DELIMITER $$

DROP PROCEDURE IF EXISTS `example`.`test` $$
CREATE PROCEDURE `example`.`test` ()
BEGIN

  DECLARE FOO varchar(7);
  DECLARE oldFOO varchar(7);
  SET FOO = '138';
  SET oldFOO = CONCAT('0', FOO);

  update mypermits
     set person = FOO
   where person = oldFOO;

END $$

DELIMITER ;

Table:

DROP TABLE IF EXISTS `example`.`mypermits`;
CREATE TABLE  `example`.`mypermits` (
  `person` varchar(7) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

INSERT INTO mypermits VALUES ('0138');

CALL test()

1. It is cards.length(), not cards.length (length is a method of java.lang.String, not an attribute).

2. It is System.out (capital 's'), not system.out. See java.lang.System.

3. It is

   for(int a = 0, b = 1; a<cards.length()-1; b=a+1, a++){
   

   not

   for(int a = 0, b = 1; a<cards.length-1; b=a+1; a++;){
   

4. Syntactically, it is if(rank == cards.substring(a,b)){, not if(rank===cards.substring(a,b){ (double equals, not triple equals; missing closing parenthesis), but to compare if two Strings are equal you need to use equals(): if(rank.equals(cards.substring(a,b))){

You should probably consider downloading Eclipse, which is an integrated development environment (not only) for Java development. Eclipse shows you the errors while you type and also provides help in fixing these. This makes it much easier to get started with Java development.

QUESTION was: suppose T john is to be converted john T, how to change in excel?

If text "T john" is in cell A1

=CONCATENATE(RIGHT(A1,LEN(A1)-2)," ",LEFT(A1,1))

and with a nod to the & crowd

=RIGHT(A1,LEN(A1)-2)&" "&LEFT(A1,1)

takes the right part of the string excluding the first 2 characters, adds a space, adds the first character.

My 2cents, in a single system user you can set the port also on /etc/ssh/ssh_config then rsync will use the port set here

@drop-shadow if you're using Hibernate, you can call Hibernate.initialize() when you invoke the getStudents() method:

Public class UniversityDaoImpl extends GenericDaoHibernate<University, Integer> implements UniversityDao {
    //...
    @Override
    public University get(final Integer id) {
        Query query = getQuery("from University u where idUniversity=:id").setParameter("id", id).setMaxResults(1).setFetchSize(1);
        University university = (University) query.uniqueResult();
        ***Hibernate.initialize(university.getStudents());***
        return university;
    }
    //...
}

Nothing. Read the documentation: Publishing Updates on Android Market

Before uploading the updated application, be sure that you have incremented the android:versionCode and android:versionName attributes in the element of the manifest file. Also, the package name must be the same and the .apk must be signed with the same private key. If the package name and signing certificate do not match those of the existing version, Market will consider it a new application and will not offer it to users as an update.

Another approach in 3.4 (don't know if this is proper Ext): You can have a delete handler like this, assuming every row has a 'delete' button.

handler: function(grid, rowIndex, colIndex) {
    var rec = grid.getStore().getAt(rowIndex);
    var id = rec.get('id');
    // some DELETE/GET ajax callback here...
    // pass in 'id' var or some key
    // inside success
    grid.getStore().removeAt(rowIndex);
}

Off the top of my head, the following are the only built-ins that are subscriptable:

string:  "foobar"[3] == "b"
tuple:   (1,2,3,4)[3] == 4
list:    [1,2,3,4][3] == 4
dict:    {"a":1, "b":2, "c":3}["c"] == 3

But mipadi's answer is correct - any class that implements __getitem__ is subscriptable

Here's another way of doing the code above using the openpyxl module that's compatible with xlsx. From what I've seen so far, it also keeps formatting.

from openpyxl import load_workbook
wb = load_workbook('names.xlsx')
ws = wb['SheetName']
ws['A1'] = 'A1'
wb.save('names.xlsx')

In iOS 10 beta 4.The right code in HTML5 is

<video src="file.mp4" webkit-playsinline="true" playsinline="true">

webkit-playsinline is for iOS < 10, and playsinline is for iOS >= 10

See details via https://webkit.org/blog/6784/new-video-policies-for-ios/

According to MSDN, the JavaScript Date object does not provide any specific date formatting methods (as you may see with other programming languages). However, you can use a few of the Date methods and formatting to accomplish your goal:

function dateToString (date) {
  // Use an array to format the month numbers
  var months = [
    "January",
    "February",
    "March",
    ...
  ];

  // Use an object to format the timezone identifiers
  var timeZones = {
    "360": "EST",
    ...
  };

  var month = months[date.getMonth()];
  var day = date.getDate();
  var year = date.getFullYear();

  var hours = date.getHours();
  var minutes = date.getMinutes();
  var time = (hours > 11 ? (hours - 11) : (hours + 1)) + ":" + minutes + (hours > 11 ? "PM" : "AM");
  var timezone = timeZones[date.getTimezoneOffset()];

  // Returns formatted date as string (e.g. January 28, 2011 - 7:30PM EST)
  return month + " " + day + ", " + year + " - " + time + " " + timezone;
}

var date = new Date("2011-01-28T19:30:00-05:00");

alert(dateToString(date));

You could even take it one step further and override the Date.toString() method:

function dateToString () { // No date argument this time
  // Use an array to format the month numbers
  var months = [
    "January",
    "February",
    "March",
    ...
  ];

  // Use an object to format the timezone identifiers
  var timeZones = {
    "360": "EST",
    ...
  };

  var month = months[*this*.getMonth()];
  var day = *this*.getDate();
  var year = *this*.getFullYear();

  var hours = *this*.getHours();
  var minutes = *this*.getMinutes();
  var time = (hours > 11 ? (hours - 11) : (hours + 1)) + ":" + minutes + (hours > 11 ? "PM" : "AM");
  var timezone = timeZones[*this*.getTimezoneOffset()];

  // Returns formatted date as string (e.g. January 28, 2011 - 7:30PM EST)
  return month + " " + day + ", " + year + " - " + time + " " + timezone;
}

var date = new Date("2011-01-28T19:30:00-05:00");
Date.prototype.toString = dateToString;

alert(date.toString());

I found this link to be useful: css-tricks fade-in fade-out css.

Here's a summary of the csstricks post:

        this.setState({toggleClass: "m-fadeIn"});
    }else{
        this.setState({toggleClass: "m-fadeOut"});
    }
}

render(){
    return (<div className={this.state.toggleClass}>Element to be toggled</div>)
}

Name your webapp WAR “ROOT.war” or containing folder “ROOT”

You just need to create your own class inherited from parent. Place an ImageView on that, and on the mousedown and mouse up events just change the images of the ImageView.

public class ImageButton extends Parent {

    private static final Image NORMAL_IMAGE = ...;
    private static final Image PRESSED_IMAGE = ...;

    private final ImageView iv;

    public ImageButton() {
        this.iv = new ImageView(NORMAL_IMAGE);
        this.getChildren().add(this.iv);

        this.iv.setOnMousePressed(new EventHandler<MouseEvent>() {

            public void handle(MouseEvent evt) {
                iv.setImage(PRESSED_IMAGE);
            }

        });

        // TODO other event handlers like mouse up

    } 

}

I cannot solve it with source ./myscript.sh. It says the source not found error.
Failed also when using . ./myscript.sh. It gives can't open myscript.sh.

So my option is put it in a text file to be called in the next script.

#!/bin/sh
echo "Perform Operation in su mode"
echo "ARCH=arm" >> environment.txt
echo "Export ARCH=arm Executed"
export PATH="/home/linux/Practise/linux-devkit/bin/:$PATH"
echo "Export path done"
export "CROSS_COMPILE='/home/linux/Practise/linux-devkit/bin/arm-arago-linux-gnueabi-' ## What's next to -?" >> environment.txt
echo "Export CROSS_COMPILE done"
# continue your compilation commands here
...

Tnen call it whenever is needed:

while read -r line; do
    line=$(sed -e 's/[[:space:]]*$//' <<<${line})
    var=`echo $line | cut -d '=' -f1`; test=$(echo $var)
    if [ -z "$(test)" ];then eval export "$line";fi
done <environment.txt

Nice jquery solution:

jQuery('a.auto-start').get(0).click();

You can even set different file name for download inside <a> tag:

Your download should start shortly. If not - you can use
<a href="/attachments-31-3d4c8970.zip" download="attachments-31.zip" class="download auto-start">direct link</a>.

You can therefore use the following formulator to calculate the right amount of pixels from a dimension specified in dp

public int convertToPx(int dp) {
    // Get the screen's density scale
    final float scale = getResources().getDisplayMetrics().density;
    // Convert the dps to pixels, based on density scale
    return (int) (dp * scale + 0.5f);
}

1.Check the Environment variables (must be set for System and not for user):

ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server
ORACLE_SID = XE

2.Check if you have the right definition in listener.ora

XE =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
    )
  )

DEFAULT_SERVICE_LISTENER = (XE)

3.Restart the service (Services > OracleServiceXE)

After that you may see a new service called OracleXETNSListenerXE.
There is already an old OracleXETNSListener.

I started both and then I was able to make a successful connection.

Edit:

If everything is running but you still can't connect, check if there is no error: ORA-12557: TNS:protocol adapter not loadable.

To correct the error go back to the Environment variables and this time edit the one called: Path. Be sure that C:\oraclexe\app\oracle\product\11.2.0\server\bin is somewhere at the beginning, definitely before any other path pointing to a different version of the Oracle DB.

There is nothing built into bootstrap for this, but some simple css could fix it. Something like this should work. Not tested though

 @media (max-width: 768px) {
      .col-xs-12.text-right, .col-xs-12.text-left {
              text-align: center;
       } 
    }

If you want to confirm if focus is with an element then

if ($('#inputId').is(':focus')) {
    //your code
}

CREATE TABLE someTable (
    id serial PRIMARY KEY,
    col1 int NOT NULL,
    col2 int NOT NULL,
    UNIQUE (col1, col2)
)

autoincrement is not postgresql. You want a serial.

If col1 and col2 make a unique and can't be null then they make a good primary key:

CREATE TABLE someTable (
    col1 int NOT NULL,
    col2 int NOT NULL,
    PRIMARY KEY (col1, col2)
)

Alternative:

library(stringr)
a = c("capitalise this", "and this")
a
[1] "capitalise this" "and this"       
str_to_title(a)
[1] "Capitalise This" "And This"

USE DatabaseName

DECLARE @ReseedBit BIT = 
    COALESCE((SELECT SUM(CONVERT(BIGINT, ic.last_value))
                FROM sys.identity_columns ic

END

DBCC CHECKIDENT ('dbo.table_name', RESEED, @Reseed);

Caveats: This is intended for use in reference data population situations where a DB is being initialized with enum type definition tables, where the ID values in those tables must always start at 1. The first time the DB is being created (e.g. during SSDT-DB publishing) @Reseed must be 0, but when resetting the data i.e. removing the data and re-inserting it, then @Reseed must be 1. So this code is intended for use in a stored procedure for resetting the DB data, which can be called manually but is also called from the post-deployment script in the SSDT-DB project. In that way the reference data inserts are only defined in one place but aren't restricted to be used only in post-deployment during publishing, they are also available for subsequent use (to support dev and automated test etc.) by calling the stored procedure to reset the DB back to a known good state.

Had a similar question and had difficulty finding an answer. The following function allows you to paste an image with a transparency parameter over another image at a specific offset.

import Image

def trans_paste(fg_img,bg_img,alpha=1.0,box=(0,0)):
    fg_img_trans = Image.new("RGBA",fg_img.size)
    fg_img_trans = Image.blend(fg_img_trans,fg_img,alpha)
    bg_img.paste(fg_img_trans,box,fg_img_trans)
    return bg_img

bg_img = Image.open("bg.png")
fg_img = Image.open("fg.png")
p = trans_paste(fg_img,bg_img,.7,(250,100))
p.show()

$scope.clearSearch = function () {
    $scope.searchAll = "";
};

I had a similarly strange problem with a file from the program e-prime (edat -> SPSS conversion), but then I discovered that there are many additional encodings you can use. this did the trick for me:

tbl <- read.delim("dir/file.txt", fileEncoding="UCS-2LE")

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

HTML/CSS Approach

If you are looking for an option that does not require much JavaScript (and and all the problems that come with it, such as rapid scroll event calls), it is possible to gain the same behavior by adding a wrapper <div> and a couple of styles. I noticed much smoother scrolling (no elements lagging behind) when I used the following approach:

JS Fiddle

HTML

<div id="wrapper">
  <div id="fixed">
    [Fixed Content]
  </div><!-- /fixed -->
  <div id="scroller">
    [Scrolling Content]
  </div><!-- /scroller -->
</div><!-- /wrapper -->

CSS

#wrapper { position: relative; }
#fixed { position: fixed; top: 0; right: 0; }
#scroller { height: 100px; overflow: auto; }

JS

//Compensate for the scrollbar (otherwise #fixed will be positioned over it).
$(function() {
  //Determine the difference in widths between
  //the wrapper and the scroller. This value is
  //the width of the scroll bar (if any).
  var offset = $('#wrapper').width() - $('#scroller').get(0).clientWidth;

  //Set the right offset
  $('#fixed').css('right', offset + 'px');?
});

Of course, this approach could be modified for scrolling regions that gain/lose content during runtime (which would result in addition/removal of scrollbars).

FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

Surprised no one has posted the type-safe C++ version yet:

template <typename T> int sgn(T val) {
    return (T(0) < val) - (val < T(0));
}

Benefits:

• Actually implements signum (-1, 0, or 1). Implementations here using copysign only return -1 or 1, which is not signum. Also, some implementations here are returning a float (or T) rather than an int, which seems wasteful.
• Works for ints, floats, doubles, unsigned shorts, or any custom types constructible from integer 0 and orderable.
• Fast! copysign is slow, especially if you need to promote and then narrow again. This is branchless and optimizes excellently
• Standards-compliant! The bitshift hack is neat, but only works for some bit representations, and doesn't work when you have an unsigned type. It could be provided as a manual specialization when appropriate.
• Accurate! Simple comparisons with zero can maintain the machine's internal high-precision representation (e.g. 80 bit on x87), and avoid a premature round to zero.

Caveats:

• It's a template so it might take longer to compile in some circumstances.
• Apparently some people think use of a new, somewhat esoteric, and very slow standard library function that doesn't even really implement signum is more understandable.

• The < 0 part of the check triggers GCC's -Wtype-limits warning when instantiated for an unsigned type. You can avoid this by using some overloads:

  template <typename T> inline constexpr
  int signum(T x, std::false_type is_signed) {
      return T(0) < x;
  }
  
  template <typename T> inline constexpr
  int signum(T x, std::true_type is_signed) {
      return (T(0) < x) - (x < T(0));
  }
  
  template <typename T> inline constexpr
  int signum(T x) {
      return signum(x, std::is_signed<T>());
  }
  

  (Which is a good example of the first caveat.)

This will explain it, I think...

import java.io.*;

class reading
{
    public static void  main(String args[]) throws IOException
    {
        float number;
        System.out.println("Enter a number");
        try
        {
            InputStreamReader in = new InputStreamReader(System.in);
            BufferedReader br = new BufferedReader(in);
            String a = br.readLine();
            number = Float.valueOf(a);
            int x = (int)number;

            System.out.println("Your input=" + number);
            System.out.println("Your input in integer terms is = " + x);
        }
        catch(Exception e){
        }
    }
}

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

Do you want to detect when the window has been resized?

You can use JQuery's resize to attach a handler.

See Creating and modifying HTML at what used to be called the Web Standards Curriculum.

Use the createElement, createTextNode and appendChild methods.

I am currently using https://github.com/kevinsawicki/http-request I like their simplicity and the way examples are shown, but mostly I was sold when I read:

What are the dependencies?

None. The goal of this library is to be a single class class with some inner static classes. The test project does require Jetty in order to test requests against an actual HTTP server implementation.

which sorted out some problems on a java 1.6 project. As for decoding json into objects gson is just invincible :)

$date = date('h:i:s A', strtotime($today . " +10 hours"));

Here's my twist on it, with a runnable example. Note this will only work in the situation where Id is unique, and you have duplicate values in other columns.

DECLARE @SampleData AS TABLE (Id int, Duplicate varchar(20))

INSERT INTO @SampleData
SELECT 1, 'ABC' UNION ALL
SELECT 2, 'ABC' UNION ALL
SELECT 3, 'LMN' UNION ALL
SELECT 4, 'XYZ' UNION ALL
SELECT 5, 'XYZ'

DELETE FROM @SampleData WHERE Id IN (
    SELECT Id FROM (
        SELECT 
            Id
            ,ROW_NUMBER() OVER (PARTITION BY [Duplicate] ORDER BY Id) AS [ItemNumber]
            -- Change the partition columns to include the ones that make the row distinct
        FROM 
            @SampleData
    ) a WHERE ItemNumber > 1 -- Keep only the first unique item
)

SELECT * FROM @SampleData

And the results:

Id          Duplicate
----------- ---------
1           ABC
3           LMN
4           XYZ

Not sure why that's what I thought of first... definitely not the simplest way to go but it works.

first enable --allow-natives-syntax on browser or node

const p = new Promise(function(resolve, reject){
    if (someCondition){
        resolve();
    } else {
        reject();
    } 
});

onClick = function () {
    %ResolvePromise(p, value)
}

Python 2.6 added a new strftime/strptime macro %f, which does microseconds. Not sure if this is documented anywhere. But if you're using 2.6 or 3.0, you can do this:

time.strptime('30/03/09 16:31:32.123', '%d/%m/%y %H:%M:%S.%f')

Edit: I never really work with the time module, so I didn't notice this at first, but it appears that time.struct_time doesn't actually store milliseconds/microseconds. You may be better off using datetime, like this:

>>> from datetime import datetime
>>> a = datetime.strptime('30/03/09 16:31:32.123', '%d/%m/%y %H:%M:%S.%f')
>>> a.microsecond
123000

use this code (in console mode):

Gem::Specification.all_names

To inspect the error message and do something with it (with Python 3)...

try:
    some_method()
except Exception as e:
    if {value} in e.args:
        {do something}

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

Another option is to use Apache Commons StrBuilder, which has the functionality that's lacking in StringBuilder.

StrBuilder.appendLn()

As of version 3.6 StrBuilder has been deprecated in favour of TextStringBuilder which has the same functionality

No, they are identical.

default(), for any value type (DateTime is a value type) will always call the parameterless constructor.

Casting int to char involves losing data and the compiler will probably warn you.

Extracting a particular byte from an int sounds more reasonable and can be done like this:

number & 0x000000ff; /* first byte */
(number & 0x0000ff00) >> 8; /* second byte */
(number & 0x00ff0000) >> 16; /* third byte */
(number & 0xff000000) >> 24; /* fourth byte */

I had the same problem when trying to load Hadoop project in eclipse. I tried the solutions above, and I believe it might have worked in Eclipse Kepler... not even sure anymore (tried too many things).

With all the problems I was having, I decided to move on to Eclipse Luna, and the solutions above did not work for me.

There was another post that recommended changing the ... tag to package. I started doing that, and it would "clear" the errors... However, I start to think that the changes would bite me later - I am not an expert on Maven.

Fortunately, I found out how to remove all the errors. Go to Window->Preferences->Maven-> Error/Warnings and change "Plugin execution not covered by lifecycle..." option to "Ignore". Hope it helps.

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

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

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

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

Python 2

I like the following:

print 'Downloading File FooFile.txt [%d%%]\r'%i,

Demo:

import time

for i in range(100):
    time.sleep(0.1)
    print 'Downloading File FooFile.txt [%d%%]\r'%i,

Python 3

print('Downloading File FooFile.txt [%d%%]\r'%i, end="")

Demo:

import time

for i in range(100):
    time.sleep(0.1)
    print('Downloading File FooFile.txt [%d%%]\r'%i, end="")

PyCharm Debugger Console with Python 3

# On PyCharm Debugger console, \r needs to come before the text.
# Otherwise, the text may not appear at all, or appear inconsistently.
# tested on PyCharm 2019.3, Python 3.6

import time

print('Start.')
for i in range(100):
    time.sleep(0.02)
    print('\rDownloading File FooFile.txt [%d%%]'%i, end="")
print('\nDone.')

Just get the Eclipse Memory Analyzer. There's nothing better out there and it's free.

JHAT is only usable for "toy applications"

The data URI format is:

data:<headers>;<encoding>,<data>

So, you need only append your data to the "data:image/jpeg;," string:

var your_binary_data = document.body.innerText.replace(/(..)/gim,'%$1'); // parse text data to URI format

window.open('data:image/jpeg;,'+your_binary_data);

Seems like the problem is with the date format.

 var d = "17-09-2013 10:08",
 dArr = d.split('-'),
 ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

Additionally, if you want to use the filter in your controller the same way you do it here:

<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
  {{ item }}
</div>

You could do something like:

var filteredItems =  $scope.$eval('items | filter:filter:criteriaMatch(criteria)');

If you want the external public IP and you're in a cloud environment like AWS or Azure, you can use the ipify_facts module:

# TODO: SECURITY: This requires that we trust ipify to provide the correct public IP. We could run our own ipify server.
- name: Get my public IP from ipify.org
  ipify_facts:

This will place the public IP into the variable ipify_public_ip.

Oxi's answer is just wrong.¹

What you want is:

var container = document.body,
element = document.getElementById('ElementID');
container.scrollTop = element.offsetTop;

Working example:

(function (){
  var i = 20, l = 20, html = '';
  while (i--){
    html += '<div id="DIV' +(l-i)+ '">DIV ' +(l-i)+ '</div>';
    html += '<a onclick="document.body.scrollTop=document.getElementById(\'DIV' +i+ '\').offsetTop">';
    html += '[ Scroll to #DIV' +i+ ' ]</a>';
    html += '<br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br /><br />';
  }
  document.write( html );
})();

¹ I haven't got enough reputation to comment on his answer

You can add this line to eclipse.ini :

-vm 
D:/work/Java/jdk1.6.0_13/bin/javaw.exe  <-- change to your JDK actual path
-vmargs <-- needs to be after -vm <path>

But it's worth setting JAVA_HOME and JRE_HOME anyway because it may not work as if the path environment points to a different java version.

Because the next one to complain will be Maven, etc.

After deserializing the JSON, you have a python object. Use the regular object methods.

In this case you have a list made of dictionaries:

json_object[0].items()

json_object[0]["title"]

etc.

System.out.println(myList.size());

Since no elements are in the list

output => 0

myList.add("newString");  // use myList.add() to insert elements to the arraylist
System.out.println(myList.size());

Since one element is added to the list

output => 1

using your comment about productCode (and assuming product code is a String) as reference...

 for(Product p : productList){
        s.put(p.getProductCode() , p);
    }

Why do people use constants in classes instead of a variable?

readability and maintainability,

having some number like 40.023 in your code doesn't say much about what the number represents, so we replace it by a word in capitals like "USER_AGE_YEARS". Later when we look at the code its clear what that number represents.

Why do we not just use a variable? Well we would if we knew the number would change, but if its some number that wont change, like 3.14159.. we make it final.

But what if its not a number like a String? In that case its mostly for maintainability, if you are using a String multiple times in your code, (and it wont be changing at runtime) it is convenient to have it as a final string at the top of the class. That way when you want to change it, there is only one place to change it rather than many.

For example if you have an error message that get printed many times in your code, having final String ERROR_MESSAGE = "Something went bad." is easier to maintain, if you want to change it from "Something went bad." to "It's too late jim he's already dead", you would only need to change that one line, rather than all the places you would use that comment.

Here is a solution on pure js. You can do it with html5 saveAs. For example this lib could be helpful: https://github.com/eligrey/FileSaver.js
Look at the demo: http://eligrey.com/demos/FileSaver.js/
P.S. There is no information about json save, but you can do it changing file type to "application/json" and format to .json

Just to clarify my comment (it's illegible in a single line)

I think the best answer is the comment by Mike Chambers in this link (http://www.judahfrangipane.com/blog/2007/02/15/error-2032-stream-error/) by Hunter McMillen.

A note from Mike Chambers:

If you run into this using URLLoader, listen for the:

flash.events.HTTPStatusEvent.HTTP_STATUS

and in AIR :

flash.events.HTTPStatusEvent.HTTP_RESPONSE_STATUS

It should give you some more information (such as the status code being returned from the server).

Using mysql CLI with -e option as Waverly360 suggests is a good one, but that might go out of memory and get killed on large results. (Havent find the reason behind it). If that is the case, and you need all records, my solution is: mysqldump + mysqldump2csv:

wget https://raw.githubusercontent.com/jamesmishra/mysqldump-to-csv/master/mysqldump_to_csv.py
mysqldump -u username -p --host=hostname database table | python mysqldump_to_csv.py > table.csv

At date git prompts:

1. use "git rm --cached <file>..." to unstage if files were not in the repo. It unstages the files keeping them there.
2. use "git reset HEAD <file>..." to unstage if the files were in the repo, and you are adding them as modified. It keeps the files as they are, and unstages them.

At my knowledge you cannot undo the git add -- but you can unstage a list of files as mentioned above.

Building on @IllidanS4 's answer, I have created a template class that allows virtually any member function with predefined arguments and class instance to be passed by reference for later calling.

template<class RET, class... RArgs> class Callback_t {
public:
    virtual RET call(RArgs&&... rargs) = 0;
    //virtual RET call() = 0;
};

template<class T, class RET, class... RArgs> class CallbackCalltimeArgs : public Callback_t<RET, RArgs...> {
public:
    T * owner;
    RET(T::*x)(RArgs...);
    RET call(RArgs&&... rargs) {
        return (*owner.*(x))(std::forward<RArgs>(rargs)...);
    };
    CallbackCalltimeArgs(T* t, RET(T::*x)(RArgs...)) : owner(t), x(x) {}
};

template<class T, class RET, class... Args> class CallbackCreattimeArgs : public Callback_t<RET> {
public:
    T* owner;
    RET(T::*x)(Args...);
    RET call() {
        return (*owner.*(x))(std::get<Args&&>(args)...);
    };
    std::tuple<Args&&...> args;
    CallbackCreattimeArgs(T* t, RET(T::*x)(Args...), Args&&... args) : owner(t), x(x),
        args(std::tuple<Args&&...>(std::forward<Args>(args)...)) {}
};

Test / example:

class container {
public:
    static void printFrom(container* c) { c->print(); };
    container(int data) : data(data) {};
    ~container() {};
    void print() { printf("%d\n", data); };
    void printTo(FILE* f) { fprintf(f, "%d\n", data); };
    void printWith(int arg) { printf("%d:%d\n", data, arg); };
private:
    int data;
};

int main() {
    container c1(1), c2(20);
    CallbackCreattimeArgs<container, void> f1(&c1, &container::print);
    Callback_t<void>* fp1 = &f1;
    fp1->call();//1
    CallbackCreattimeArgs<container, void, FILE*> f2(&c2, &container::printTo, stdout);
    Callback_t<void>* fp2 = &f2;
    fp2->call();//20
    CallbackCalltimeArgs<container, void, int> f3(&c2, &container::printWith);
    Callback_t<void, int>* fp3 = &f3;
    fp3->call(15);//20:15
}

Obviously, this will only work if the given arguments and owner class are still valid. As far as readability... please forgive me.

Edit: removed unnecessary malloc by making the tuple normal storage. Added inherited type for the reference. Added option to provide all arguments at calltime instead. Now working on having both....

Edit 2: As promised, both. Only restriction (that I see) is that the predefined arguments must come before the runtime supplied arguments in the callback function. Thanks to @Chipster for some help with gcc compliance. This works on gcc on ubuntu and visual studio on windows.

    return new wintypename CallbackFactory<RET, RArgs...>::Callback<U, CArgs...>(owner, func, std::forward<CArgs>(cargs)...);
}

It would be easier to make suggestions if you provided example code and data.

Accessing the dictionary is unlikely to be a problem as that operation is O(1) on average, and O(N) amortized worst case. It's possible that the built-in hashing functions are experiencing collisions for your data. If you're having problems with has the built-in hashing function, you can provide your own.

Python's dictionary implementation reduces the average complexity of dictionary lookups to O(1) by requiring that key objects provide a "hash" function. Such a hash function takes the information in a key object and uses it to produce an integer, called a hash value. This hash value is then used to determine which "bucket" this (key, value) pair should be placed into.

You can overwrite the __hash__ method in your class to implement a custom hash function like this:

def __hash__(self):    
    return hash(str(self))

Depending on what your data actually looks like, you might be able to come up with a faster hash function that has fewer collisions than the standard function. However, this is unlikely. See the Python Wiki page on Dictionary Keys for more information.

AddCharset utf-8 .html .css .php .txt .js

This is for those that do not have access to their server's conf file. It is just one more thing to try when other attempts failed.

As far as performance issues regarding the use of .htaccess I have not seen this. My typical page load times are 150-200 mS with or without .htaccess

What good is performance if your page does not render correctly. Most shared servers do not allow user access to the config file which is the preferred place to add a character set.

Try use While/Wend and Do While / Loop statements...

i = 1
While i < N + 1
Do While true
    [Code]
    If Condition1 Then
       Exit Do
    End If

    [MoreCode]
    If Condition2 Then
       Exit Do
    End If

    [...]

    Exit Do

Here's a lazy version of @stephen's answer

import html.parser
import itertools
import urllib.request

class LinkParser(html.parser.HTMLParser):
    def reset(self):
        super().reset()
        self.links = iter([])

    def handle_starttag(self, tag, attrs):
        if tag == 'a':
            for (name, value) in attrs:
                if name == 'href':
                    self.links = itertools.chain(self.links, [value])


def gen_links(stream, parser):

    for line in stream:

Use it like so:

>>> links = gen_links(stream, parser)
>>> next(links)
'//stackoverflow.com'

Simple method to get the records count:

You can use ARG - see https://docs.docker.com/engine/reference/builder/#arg

The ARG instruction defines a variable that users can pass at build-time to the builder with the docker build command using the --build-arg <varname>=<value> flag. If a user specifies a build argument that was not defined in the Dockerfile, the build outputs an error.

For my flash messages I was happy with $form->getErrorsAsString()

Edit (from Benji_X80): For SF3 use $form->getErrors(true, false);

<style type="text/css">
td { word-wrap: break-word;max-width:50px; }            
</style>

A very basic example of Implicits in scala.

Implicit parameters:

val value = 10
implicit val multiplier = 3
def multiply(implicit by: Int) = value * by
val result = multiply // implicit parameter wiil be passed here
println(result) // It will print 30 as a result

Note: Here multiplier will be implicitly passed into the function multiply. Missing parameters to the function call are looked up by type in the current scope meaning that code will not compile if there is no implicit variable of type Int in the scope.

Implicit conversions:

implicit def convert(a: Double): Int = a.toInt
val res = multiply(2.0) // Type conversions with implicit functions
println(res)  // It will print 20 as a result

Note: When we call multiply function passing a double value, the compiler will try to find the conversion implicit function in the current scope, which converts Int to Double (As function multiply accept Int parameter). If there is no implicit convert function then the compiler will not compile the code.

Hi you can used this code in pure css

as like this

css

.arrow {
cursor: pointer;
color: white;
border: 1px solid #AEAEAE;
border-radius: 30px;
background: #605F61;
font-size: 31px;
font-weight: bold;
display: inline-block;
line-height: 0px;
padding: 11px 3px;
}
.arrow:before{
 content: "×";
}

HTML

<a href="#" class="arrow"> 
</a>

? Live demo http://jsfiddle.net/rohitazad/VzZhU/

import httr package

library(httr)

Get the url

url <- "http://www.omdbapi.com/?apikey=72bc447a&t=Annie+Hall&y=&plot=short&r=json"
resp <- GET(url)

Print content of resp as text

content(resp, as = "text")

Print content of resp

content(resp)

Use content() to get the content of resp, but this time do not specify a second argument. R figures out automatically that you're dealing with a JSON, and converts the JSON to a named R list.

listview.setOnItemLongClickListener(new OnItemLongClickListener() {

        @Override
        public boolean onItemLongClick(final AdapterView<?> parent, View view,
                final int position, long id) {
            // TODO Auto-generated method stub

             parent.getChildAt(position).setBackgroundColor(getResources().getColor(R.color.listlongclick_selection));

            return false;
        }
    });

You can also make two random integers and verify if they are the same, this gives you more control over the probabilities.

Random rand = new Random();

Declare a range to manage random probability. In this example, there is a 50% chance of being true.

int range = 2;

Generate 2 random integers.

int a = rand.nextInt(range);
int b = rand.nextInt(range);

Then simply compare return the value.

return a == b; 

I also have a class you can use. RandomRange.java

Use Not IsEmpty().

For example:

Sub DoStuffIfNotEmpty()
    If Not IsEmpty(ActiveCell.Value) Then
        MsgBox "I'm not empty!"
    End If
End Sub

This answer is based on the ones provided by @Sasan and @CAD bloke.

If you wish to use this in .NET Standard 2 or don't want Newtonsoft, see Xaniff's answer below

Works only with EF Core 2.1+ (not .NET Standard compatible)(Newtonsoft JsonConvert)

builder.Entity<YourEntity>().Property(p => p.Strings)
    .HasConversion(
        v => JsonConvert.SerializeObject(v),
        v => JsonConvert.DeserializeObject<List<string>>(v));

Using the EF Core fluent configuration we serialize/deserialize the List to/from JSON.

Why this code is the perfect mix of everything you could strive for:

• The problem with Sasn's original answer is that it will turn into a big mess if the strings in the list contains commas (or any character chosen as the delimiter) because it will turn a single entry into multiple entries but it is the easiest to read and most concise.
• The problem with CAD bloke's answer is that it is ugly and requires the model to be altered which is a bad design practice (see Marcell Toth's comment on Sasan's answer). But it is the only answer that is data-safe.

In Bootstrap 3.3.x make sure you use the scrollspy JavaScript capability to track active elements. It's easy to include it in your HTML. Just do the following:

<body data-spy="scroll" data-target="Id or class of the element you want to track">

In most cases I usually track active elements on my navbar, so I do the following:

<body data-spy="scroll" data-target=".navbar-fixed-top" >

Now in your CSS you can target .navbar-fixed-top .active a:

.navbar-fixed-top .active a { 
    // Put in some styling 
}

This should work if you are tracking active li elements in your top fixed navigation bar.

use std::map< std::string, std::map<std::string, std::string> >::const_iterator when map is const.

In my case I chose the Force Update checkbox while pushing. It worked like a charm.

What happens if the fragment that you want to remove is not on top of the stack?

Then you can use theses functions

popBackStack(int arg0, int arg1);

popBackStack(String arg0, int arg1);

Are you missing a using directive for System.Linq?

For Python 2 give execfile a try. (See other answers for Python 3)

execfile('file.py')

Example usage:
Let's use "copy con" to quickly create a small script file...

C:\junk>copy con execfile_example.py
a = [9, 42, 888]
b = len(a)
^Z
        1 file(s) copied.

...and then let's load this script like so:

C:\junk>\python27\python
Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> execfile('execfile_example.py')
>>> a
[9, 42, 888]
>>> b
3
>>>

Use

Ctrl + SHIFT + L which will open a list of all major shortcuts for eclipse.

1. For single line java code comment and uncomment : Ctrl + / (Forward Slash)

2. For multiple line java code comment : Ctrl + Shift + / (Forward Slash) and

   Multiline uncomment : Ctrl + Shift + \ (Backslash)

3. For single line xhtml code comment/uncomment : Ctrl + Shift + c

4. For multiple line xhtml code comment : Ctrl + Shift + / (Forward Slash)

   For multiple uncomment : Ctrl + Shift + \ (Backward Slash)

For Mac user it will be: ? instead of Ctrl

Use saveAs on FileSaver.js github project.

FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it.

You need that it breaks the outer if statement. Why do you use second else?

IF condition THEN  
    IF condition THEN 
        sequence 1
    // ELSE sequence 4
       // break //?  
    // ENDIF    
ELSE    
    sequence 3    
ENDIF

In Oracle:

This gets the key of the max(high_val) in the table according to the range.

select high_val, my_key
from (select high_val, my_key
      from mytable
      where something = 'avalue'
      order by high_val desc)
where rownum <= 1

use code like this:

new Guid("9D2B0228-4D0D-4C23-8B49-01A698857709")

instead of "9D2B0228-4D0D-4C23-8B49-01A698857709" you can set your string value

As @AliK mentioned, this can be done easily by looking at the value of the submit buttons.

When you submit a form, unset variables will evaluate false. If you set both submit buttons to be part of the same form, you can just check and see which button has been set.

HTML:

<form action="handle_user.php" method="POST" />
  <input type="submit" value="Save" name="save" />
  <input type="submit" value="Submit for Approval" name="approve" />
</form>

PHP

if($_POST["save"]) {
  //User hit the save button, handle accordingly
}
//You can do an else, but I prefer a separate statement
if($_POST["approve"]) {
  //User hit the Submit for Approval button, handle accordingly
}

EDIT

Related:

• 2x submit buttons to action different URL
• Submit form to another page (which is different from the page used in ACTION)

This can be resolved by specifying the specific column names desired from the specific table like so:

$c = Customer::leftJoin('orders', function($join) {
      $join->on('customers.id', '=', 'orders.customer_id');
    })
    ->whereNull('orders.customer_id')
    ->first([
        'customers.id',
        'customers.first_name',
        'customers.last_name',
        'customers.email',
        'customers.phone',
        'customers.address1',
        'customers.address2',
        'customers.city',
        'customers.state',
        'customers.county',
        'customers.district',
        'customers.postal_code',
        'customers.country'
    ]);

Here in this case, we are having 3 parameter's in the Method namely ModelandView.
According to this question, the first parameter is easily understood. It represents the View which will be displayed to the client.
The other two parameters are just like The Pointer and The Holder
Hence you can sum it up like this

ModelAndView(View, Pointer, Holder);

The Pointer just points the information in the The Holder

When the Controller binds the View with this information, then in the said process, you can use The Pointer in the JSP page to access the information stored in The Holder to display that respected information to the client.
Here is the visual depiction of the respected process.

return new ModelAndView("welcomePage", "WelcomeMessage", message);

Broadly speaking, spark Executor JVM memory can be divided into two parts. Spark memory and User memory. This is controlled by property spark.memory.fraction - the value is between 0 and 1. When working with images or doing memory intensive processing in spark applications, consider decreasing the spark.memory.fraction. This will make more memory available to your application work. Spark can spill, so it will still work with less memory share.

The second part of the problem is division of work. If possible, partition your data into smaller chunks. Smaller data possibly needs less memory. But if that is not possible, you are sacrifice compute for memory. Typically a single executor will be running multiple cores. Total memory of executors must be enough to handle memory requirements of all concurrent tasks. If increasing executor memory is not a option, you can decrease the cores per executor so that each task gets more memory to work with. Test with 1 core executors which have largest possible memory you can give and then keep increasing cores until you find the best core count.

I solve this problem by adding extension method to IEnumerable.

public static class DataTableEnumerate
{
    public static void Fill<T> (this IEnumerable<T> Ts, ref DataTable dt) where T : class
    {
        //Get Enumerable Type
        Type tT = typeof(T);

        //Get Collection of NoVirtual properties
        var T_props = tT.GetProperties().Where(p => !p.GetGetMethod().IsVirtual).ToArray();

        //Fill Schema
        foreach (PropertyInfo p in T_props)
            dt.Columns.Add(p.Name, p.GetMethod.ReturnParameter.ParameterType.BaseType);

        //Fill Data
        foreach (T t in Ts)
        {
            DataRow row = dt.NewRow();

            foreach (PropertyInfo p in T_props)
                row[p.Name] = p.GetValue(t);

            dt.Rows.Add(row);
        }

    }
}

This is way too vague to give you an answer relevant to your specific case. It depends on a lot of things. Jeff Atwood (founder of this site) actually wrote about this. For the most part, though, if you have the right indexes and you properly do your JOINs it is usually going to be faster to do 1 trip than several.

Can also invoke oShell.Exec in order to be able to read STDIN/STDOUT/STDERR responses. Perfect for error checking which it seems you're doing with your sanity .BAT.

If you can't put value on buttons. I have just a rough solution. Put a hidden field. And when one of the buttons are clicked before submitting, populate the value of hidden field with like say 1 when first button clicked and 2 if second one is clicked. and in submit page check for the value of this hidden field to determine which one is clicked.

I tried this and worked for me.

success: function (response) {
    document.getElementById('packageItems').value = response.package_items;

    ClassicEditor
    .create(document.querySelector('#packageItems'), {
        removePlugins: ['dragdrop']
    })
    .then(function (editor) {
        editor.setData(response.package_items);
    })
    .catch(function (err) {
        console.error(err);
    });
},

If you want to reduce the size to decimal(7,2) from decimal(9,2) you will have to account for the existing data with values greater to fit into decimal(7,2). Either you will have to delete those numbers are truncate it down to fit into your new size. If there was no data for the field you are trying to update it will do it automatically without issues

I had a similar issue and solved it with a patch to ec2.py and adding some configuration parameters to ec2.ini. The patch takes the value of ec2_key_name, prefixes it with the ssh_key_path, and adds the ssh_key_suffix to the end, and writes out ansible_ssh_private_key_file as this value.

The following variables have to be added to ec2.ini in a new 'ssh' section (this is optional if the defaults match your environment):

[ssh]
# Set the path and suffix for the ssh keys
ssh_key_path = ~/.ssh
ssh_key_suffix = .pem

Here is the patch for ec2.py:

204a205,206
>     'ssh_key_path': '~/.ssh',
>     'ssh_key_suffix': '.pem',
422a425,428
>         # SSH key setup
>         self.ssh_key_path = os.path.expanduser(config.get('ssh', 'ssh_key_path'))
>         self.ssh_key_suffix = config.get('ssh', 'ssh_key_suffix')
> 
1490a1497
>         instance_vars["ansible_ssh_private_key_file"] = os.path.join(self.ssh_key_path, instance_vars["ec2_key_name"] + self.ssh_key_suffix)

For MS compilers:

#define inc_enum(i) ((decltype(i)) ((int)i + 1))

enum enumtype { one, two, three, count};
for(enumtype i = one; i < count; i = inc_enum(i))
{ 
    dostuff(i); 
}

Note: this is a lot less code than the simple templatized custom iterator answer.

You can get this to work with GCC by using typeof instead of decltype, but I don't have that compiler handy at the moment to make sure it compiles.

 private void Add_Click(object sender, EventArgs e) {
 OleDbConnection con = new OleDbConnection(@ "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\Users\HP\Desktop\DS Project.mdb");
 OleDbCommand cmd = con.CreateCommand();
 con.Open();
 cmd.CommandText = "Insert into DSPro (Playlist) values('" + textBox1.Text + "')";
 cmd.ExecuteNonQuery();
 MessageBox.Show("Record Submitted", "Congrats");
 con.Close();
} 

I use this method because for some reason, none of the other solutions proposed actually worked for me. I promise I tried.

section {
   position: relative;
   border-top: 52px solid transparent; /* navbar height +2 */
   margin: -30px 0 0;

   background-clip: padding-box;
}

   content: "";
   position: absolute;
   top: -2px;
   left: 0;
   right: 0;
   border-top: 2px solid transparent;
}

Replace section by a class if you prefer.

For those who do not believe me I kindly prepared a jsfiddle with the solution in it: SOLUTION

sizeOf = function (bytes) {
  if (bytes == 0) { return "0.00 B"; }
  var e = Math.floor(Math.log(bytes) / Math.log(1024));
  return (bytes/Math.pow(1024, e)).toFixed(2)+' '+' KMGTP'.charAt(e)+'B';
}

sizeOf(2054110009);
//=> "1.91 GB"

sizeOf(7054110);
//=> "6.73 MB"

sizeOf( (3*1024*1024) );
//=> "3.00 MB"

I'll add another case where I was getting the same error but just being a dummy. I had added [routerLinkActiveOptions]="{exact: true}" without yet adding routerLinkActive="active".

My incorrect code was

<a class="nav-link active" routerLink="/dashboard" [routerLinkActiveOptions]="{exact: true}">
  Home
</a>

when it should have been

<a class="nav-link active" routerLink="/dashboard" routerLinkActive="active" [routerLinkActiveOptions]="{exact: true}">
  Home
</a>

Without having routerLinkActive, you can't have routerLinkActiveOptions.

You can find record by month, day, year etc of dates by Date Aggregation Operators, like $dayOfYear, $dayOfWeek, $month, $year etc.

As an example if you want all the orders which are created in April 2016 you can use below query.

db.getCollection('orders').aggregate(
   [
     {
       $project:
         {
           doc: "$$ROOT",
           year: { $year: "$created" },
           month: { $month: "$created" },
           day: { $dayOfMonth: "$created" }
         }
     },
     { $match : { "month" : 4, "year": 2016 } }
   ]
)

Here created is a date type field in documents, and $$ROOT we used to pass all other field to project in next stage, and give us all the detail of documents.

You can optimize above query as per your need, it is just to give an example. To know more about Date Aggregation Operators, visit the link.

Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.

SEND Button logic:

string fromaddr = "[email protected]";
string toaddr = TextBox1.Text;//TO ADDRESS HERE
string password = "YOUR PASSWROD";

MailMessage msg = new MailMessage();
msg.Subject = "Username &password";
msg.From = new MailAddress(fromaddr);
msg.Body = "Message BODY";
msg.To.Add(new MailAddress(TextBox1.Text));
SmtpClient smtp = new SmtpClient();
smtp.Host = "smtp.gmail.com";
smtp.Port = 587;
smtp.UseDefaultCredentials = false;
smtp.EnableSsl = true;
NetworkCredential nc = new NetworkCredential(fromaddr,password);
smtp.Credentials = nc;
smtp.Send(msg);

This code work 100%. If you have antivirus in your system or firewall that restrict sending mails from your system so disable your antivirus and firewall. After this run this code... In this above code TextBox1.Text control is used for TOaddress.

Centering something absolutely positioned is rather convoluted in CSS.

ul#slideshow li {
    position: absolute;
    left:50%;
    margin-left:-20px;

}

Change margin-left to (negative) half the width of the element you are trying to center.

You fiddle already does the job ... maybe you try to get the string before the double colon? (you really should edit your question) Then the code would go like this:

str.substring(0, str.indexOf(":"));

Where 'str' represents the variable with your string inside.

Click here for JSFiddle Example

Javascript

var input_string = document.getElementById('my-input').innerText;
var output_element = document.getElementById('my-output');

var left_text = input_string.substring(0, input_string.indexOf(":"));

output_element.innerText = left_text;

Html

<p>
  <h5>Input:</h5>
  <strong id="my-input">Left Text:Right Text</strong>
  <h5>Output:</h5>
  <strong id="my-output">XXX</strong>
</p>

CSS

body { font-family: Calibri, sans-serif; color:#555; }
h5 { margin-bottom: 0.8em; }
strong {
  width:90%;
  padding: 0.5em 1em;
  background-color: cyan;
}
#my-output { background-color: gold; }

This works fine too:

HttpContext.Current.Server.MapPath(relativePath)

Where relative path is something like "~/foo/file.jpg"

My problem was unrelated to processData. It was because I sent a function that cannot be called later with apply because it did not have enough arguments. Specifically I shouldn't have used alert as the error callback.

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    processData: false,
    error: alert
});

See this answer for more information on why that can be a problem: Why are certain function calls termed "illegal invocations" in JavaScript?

The way I was able to discover this was by adding a console.log(list[ firingIndex ]) to jQuery so I could track what it was firing.

This was the fix:

function myError(jqx, textStatus, errStr) {
    alert(errStr);
}

$.ajax({
    url: csvApi,
    success: parseCsvs,
    dataType: "json",
    timeout: 5000,
    error: myError // Note that passing `alert` instead can cause a "jquery.js:3189 Uncaught TypeError: Illegal invocation" sometimes
});

scrollHeight is a regular javascript property so you don't need jQuery.

var test = document.getElementById("foo").scrollHeight;

Following worked for me!

2. select "login" on the left pane
3. look for the key which is causing this issue. Mine was iOS Developer...
4. double-click the key and select "Allow access to all programs" in the access column

Restart Xcode and try to build again. It will ask you again but with the additional option to "Always allow. Enter your macOS user password as password and press "Always allow".

Let me know if it worked for you.

moment was perfect for what I needed. NOTE it ignores the hours and minutes and just does it's thing if you let it. This was perfect for me as my API call brings back the date and time but I only care about the date.

function momentTest() {

  var varDate = "2018-01-19 18:05:01.423";
  var myDate =  moment(varDate,"YYYY-MM-DD").format("DD-MM-YYYY");
  var todayDate = moment().format("DD-MM-YYYY");  
  var yesterdayDate = moment().subtract(1, 'days').format("DD-MM-YYYY");   
  var tomorrowDate = moment().add(1, 'days').format("DD-MM-YYYY");

  alert(todayDate);

  if (myDate == todayDate) {
    alert("date is today");
  } else if (myDate == yesterdayDate) {
    alert("date is yesterday");
  } else if (myDate == tomorrowDate) {
    alert("date is tomorrow");
  } else {
    alert("It's not today, tomorrow or yesterday!");
  }
}

You have not one, but many mistakes. It should be:

int[] tall = new int[28123];

for (int j=0;j<28123;j++){
    tall[j] = j+1;
}

Your code is putting a 0 in all the positions of the array.

Morover, it'll throw an exception, because the last index of the array is 28123-1 (arrays in Java start in 0!).

You can also use the NSString class methods which will also create an autoreleased instance and have more options like string formatting:

NSString *myString = [NSString stringWithString:@"abc"];
NSString *myString = [NSString stringWithFormat:@"abc %d efg", 42];

The syntax is changed in new 3.x releases rather than old 2.x releases: for example in python 2.x you can write: print "Hi new world" but in the new 3.x release you need to use the new syntax and write it like this: print("Hi new world")

check the documentation: http://docs.python.org/3.3/library/functions.html?highlight=print#print

in Swift 4.2 this works.

import Foundation

class myThread: Thread
{
    override func main() {
        while(true) {
            print("Running in the Thread");
            Thread.sleep(forTimeInterval: 4);
        }
    }
}

let t = myThread();
t.start();

while(true) {
    print("Main Loop");
    sleep(5);
}

Another 2 very usefull shortcuts are to move lines selected up and down, like sublime text does...

{
  "key" : "ctrl+shift+down", "command" : "editor.action.moveLinesDownAction",
  "when" : "editorTextFocus && !editorReadonly"
},

and

{
  "key" : "ctrl+shift+up", "command" : "editor.action.moveLinesUpAction",
  "when" : "editorTextFocus && !editorReadonly"
}

? is called Ternary (conditional) operator : example

Probably the best way is to handle the trailing white spaces when you read your data file. If you use read.csv or read.table you can set the parameterstrip.white=TRUE.

If you want to clean strings afterwards you could use one of these functions:

# Returns string without leading white space
trim.leading <- function (x)  sub("^\\s+", "", x)

# Returns string without trailing white space
trim.trailing <- function (x) sub("\\s+$", "", x)

# Returns string without leading or trailing white space
trim <- function (x) gsub("^\\s+|\\s+$", "", x)

To use one of these functions on myDummy$country:

 myDummy$country <- trim(myDummy$country)

To 'show' the white space you could use:

 paste(myDummy$country)

which will show you the strings surrounded by quotation marks (") making white spaces easier to spot.

In the spirit of changing the rendering instead of changing the content, the following CSS makes each newline behave like a <br>:

white-space: pre;
white-space: pre-line;

Why two rules: pre-line only affects newlines (thanks for the clue, @KevinPauli). IE6-7 and other old browsers fall back to the more extreme pre which also includes nowrap and renders multiple spaces. Details on these and other settings (pre-wrap) at mozilla and css-tricks (thanks @Sablefoste).

While I'm generally averse to the S.O. predilection for second-guessing the question rather than answering it, in this case replacing newlines with <br> markup may increase vulnerability to injection attack with unwashed user input. You're crossing a bright red line whenever you find yourself changing .text() calls to .html() which the literal question implies would have to be done. (Thanks @AlexS for highlighting this point.) Even if you rule out a security risk at the time, future changes could unwittingly introduce it. Instead, this CSS allows you to get hard line breaks without markup using the safer .text().

You can just return ItemViewType and use it. See below code:

@Override
public int getItemViewType(int position) {

    Message item = messageList.get(position);
    // return my message layout
    if(item.getUsername() == Message.userEnum.I)
        return R.layout.item_message_me;
    else
        return R.layout.item_message; // return other message layout
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int viewType) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(viewType, viewGroup, false);
    return new ViewHolder(view);
}

Use substring function
Check this out http://jsfiddle.net/kuc5as83/

var string = "1234567890"
var substr=string.substr(-8);
document.write(substr);

Output >> 34567890

substr(-8) will keep last 8 chars

var substr=string.substr(8);
document.write(substr);

Output >> 90

substr(8) will keep last 2 chars

var substr=string.substr(0, 8);
document.write(substr);

Output >> 12345678

substr(0, 8) will keep first 8 chars

Check this out string.substr(start,length)

You can use ''; to declaring NULL variable in Javascript

You can use pandas.Series.map :

df['col'].map('str{}'.format)

It will apply the word "str" before all your values.

Thanx to @Jota.Toledo, I got the solution for my table creation. Please find the working code below:

component.html

<mat-table #table [dataSource]="dataSource" matSort>
  <ng-container matColumnDef="{{column.id}}" *ngFor="let column of columnNames">
    <mat-header-cell *matHeaderCellDef mat-sort-header> {{column.value}}</mat-header-cell>
    <mat-cell *matCellDef="let element"> {{element[column.id]}}</mat-cell>
  </ng-container>

  <mat-header-row *matHeaderRowDef="displayedColumns"></mat-header-row>
  <mat-row *matRowDef="let row; columns: displayedColumns;"></mat-row>
</mat-table>

component.ts

import { Component, OnInit, ViewChild } from '@angular/core';
import { MatTableDataSource, MatSort } from '@angular/material';
import { DataSource } from '@angular/cdk/table';

@Component({
  selector: 'app-m',
  templateUrl: './m.component.html',
  styleUrls: ['./m.component.css'],
})
export class MComponent implements OnInit {

  dataSource;
  displayedColumns = [];
  @ViewChild(MatSort) sort: MatSort;

  /**
   * Pre-defined columns list for user table
   */
  columnNames = [{
    id: 'position',
    value: 'No.',

  }, {
    id: 'name',
    value: 'Name',
  },
    {
      id: 'weight',
      value: 'Weight',
    },
    {
      id: 'symbol',
      value: 'Symbol',
    }];

  ngOnInit() {
    this.displayedColumns = this.columnNames.map(x => x.id);
    this.createTable();
  }

  createTable() {
    let tableArr: Element[] = [{ position: 1, name: 'Hydrogen', weight: 1.0079, symbol: 'H' },
      { position: 2, name: 'Helium', weight: 4.0026, symbol: 'He' },
      { position: 3, name: 'Lithium', weight: 6.941, symbol: 'Li' },
      { position: 4, name: 'Beryllium', weight: 9.0122, symbol: 'Be' },
      { position: 5, name: 'Boron', weight: 10.811, symbol: 'B' },
      { position: 6, name: 'Carbon', weight: 12.0107, symbol: 'C' },
    ];
    this.dataSource = new MatTableDataSource(tableArr);
    this.dataSource.sort = this.sort;
  }
}

export interface Element {
  position: number,
  name: string,
  weight: number,
  symbol: string
}

app.module.ts

imports: [
  MatSortModule,
  MatTableModule,
],

you can also use andSelf() method to get wrapper DOM contain then find() can be work around as your idea

$(function() {_x000D_
  $('.slide-link').andSelf().find('[data-slide="0"]').addClass('active');_x000D_
})

.active {_x000D_
  background: green;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<a class="slide-link" href="#" data-slide="0">1</a>_x000D_
<a class="slide-link" href="#" data-slide="1">2</a>_x000D_
<a class="slide-link" href="#" data-slide="2">3</a>

Batch files are not an executable. They need an application to run them (i.e. cmd).

On UNIX, the script file has shebang (#!) at the start of a file to specify the program that executes it. Double-clicking in Windows is performed by Windows Explorer. CreateProcess does not know anything about that.

Runtime.
   getRuntime().
   exec("cmd /c start \"\" build.bat");

Note: With the start \"\" command, a separate command window will be opened with a blank title and any output from the batch file will be displayed there. It should also work with just `cmd /c build.bat", in which case the output can be read from the sub-process in Java if desired.

Use this:

([^,;]*[,;])*

Several possibilities:

• You have safe mode enabled. That way, only exec() is working, and then only on executables in safe_mode_exec_dir
• exec and shell_exec are disabled in php.ini
• The path to the executable is wrong. If the script is in the same directory as the php file, try exec(dirname(__FILE__) . '/myscript.sh');

I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

Use the -cp or -classpath switch.

$ java -help  
Usage: java [-options] class [args...]  
           (to execute a class)  
   or  java [-options] -jar jarfile [args...]  
           (to execute a jar file)  

where options include:  
...  
    -cp <class search path of directories and zip/jar files>  
    -classpath <class search path of directories and zip/jar files>  
                  A ; separated list of directories, JAR archives,  
                  and ZIP archives to search for class files.  

(Note that the separator used to separate entries on the classpath differs between OSes, on my Windows machine it is ;, in *nix it is usually :.)

IMPORTANT NOTE: You have to sort your data first.

The part I didn't get is that in the example construction

groups = []
uniquekeys = []
for k, g in groupby(data, keyfunc):
   groups.append(list(g))    # Store group iterator as a list
   uniquekeys.append(k)

k is the current grouping key, and g is an iterator that you can use to iterate over the group defined by that grouping key. In other words, the groupby iterator itself returns iterators.

Here's an example of that, using clearer variable names:

from itertools import groupby

things = [("animal", "bear"), ("animal", "duck"), ("plant", "cactus"), ("vehicle", "speed boat"), ("vehicle", "school bus")]

for key, group in groupby(things, lambda x: x[0]):
    for thing in group:
        print("A %s is a %s." % (thing[1], key))
    print("")
    

This will give you the output:

A bear is a animal.
A duck is a animal.

A cactus is a plant.

A speed boat is a vehicle.
A school bus is a vehicle.

In this example, things is a list of tuples where the first item in each tuple is the group the second item belongs to.

The groupby() function takes two arguments: (1) the data to group and (2) the function to group it with.

Here, lambda x: x[0] tells groupby() to use the first item in each tuple as the grouping key.

In the above for statement, groupby returns three (key, group iterator) pairs - once for each unique key. You can use the returned iterator to iterate over each individual item in that group.

Here's a slightly different example with the same data, using a list comprehension:

for key, group in groupby(things, lambda x: x[0]):
    listOfThings = " and ".join([thing[1] for thing in group])
    print(key + "s:  " + listOfThings + ".")

This will give you the output:

animals: bear and duck.
plants: cactus.
vehicles: speed boat and school bus.

You will not be able to restrict the file type that the user uploads at the client side[*]. You'll only be able to do this at the server side. If a user uploads an incorrect file you will only be able to recognise that once the file is uploaded uploaded. There is no reliable and safe way to stop a user uploading whatever file format they want.

[*] yes, you can do all kinds of clever stuff to detect the file extension before starting the upload, but don't rely on it. Someone will get around it and upload whatever they like sooner or later.

There is a proposal open in GitHub for the C# language about having better support for raw string literals. One valid answer, is to encourage the C# team to add a new feature to the language (such as triple quote - like Python).

see https://github.com/dotnet/csharplang/discussions/89#discussioncomment-257343

If the number of arguments should be an exact number (less or equal to 9), then this is a simple way to check it:

if "%2" == "" goto args_count_wrong
if "%3" == "" goto args_count_ok

:args_count_wrong
echo I need exactly two command line arguments
exit /b 1

:args_count_ok

Very similar to this question, and I would suggest the same formula in column D, albeit a few changes to the ranges:

=IFERROR(VLOOKUP(C1, A:B, 2, 0), "")

If you wanted to use match, you'd have to use INDEX as well, like so:

=IFERROR(INDEX(B:B, MATCH(C1, A:A, 0)), "")

but this is really lengthy to me and you need to know how to properly use two functions (or three, if you don't know how IFERROR works)!

Note: =IFERROR() can be a substitute of =IF() and =ISERROR() in some cases :)

You can use this as well:

values = np.array([[1,2,3],[4,5,6]])
values[...,0] # first column
#[1,4]

Note: This is not working for built-in array and not aligned (e.g. np.array([[1,2,3],[4,5,6,7]]) )

In AppDelegate.swift you can add the following code:

let sb = UIStoryboard(name: "Main", bundle: nil)
let vc = sb.instantiateViewController(withIdentifier: "YourViewController_StorboardID")
self.window?.rootViewController = vc
self.window?.makeKeyAndVisible()

Of course, you need to implement your logic, based on which criteria you'll choose an appropriate view controller.

Also, don't forget to add an identity (select storyboard -> Controller Scene -> Show the identity inspector -> assign StorboardID).

If you have JQuery loaded already, you can just do this:

$('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');

EDIT:

First load JQuery in the head tag:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>

Then call the Javascript to change the background image when something happens on the page, like when it finishes loading:

<script type="text/javascript">
    $(document).ready(function() {
        $('body').css('background-image', 'url(../images/backgrounds/header-top.jpg)');
    });
</script>

You can use unescapeJava from org.apache.commons.text.StringEscapeUtils like below

str = "hello\r\njava\r\nbook";
StringEscapeUtils.unescapeJava(str);

Simple & Best way:

onclick="parentNode.remove()"

Deletes the complete parent from html

Good question,

Usually the DB engine should automatically select the index to use based on query execution plans it builds. However, there are some pretty rare cases when you want to force the DB to use a specific index.

To be able to answer your specific question you have to specify the DB you are using.

For MySQL, you want to read the Index Hint Syntax documentation on how to do this
