I did it like this in my Jtable its autorefreshing after 300 ms;

DefaultTableModel tableModel = new DefaultTableModel(){
public boolean isCellEditable(int nRow, int nCol) {
                return false;
            }
};
JTable table = new JTable();

Timer t = new Timer(300, new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                addColumns();
                remakeData(set);
                table.setModel(model);
            }
        });
        t.start();

private void addColumns() {
        model.setColumnCount(0);
        model.addColumn("NAME");
            model.addColumn("EMAIL");} 

 private void remakeData(CollectionType< Objects > name) {
    model.setRowCount(0);
    for (CollectionType Objects : name){
    String n = Object.getName();
    String e = Object.getEmail();
    model.insertRow(model.getRowCount(),new Object[] { n,e });
    }}

I doubt it will do good with large number of objects like over 500, only other way is to implement TableModelListener in your class, but i did not understand how to use it well. look at http://download.oracle.com/javase/tutorial/uiswing/components/table.html#modelchange

Just simple like this:

    tbl.addMouseListener(new MouseListener() {
        @Override
        public void mouseReleased(MouseEvent e) {
        }
        @Override
        public void mousePressed(MouseEvent e) {
            String selectedCellValue = (String) tbl.getValueAt(tbl.getSelectedRow() , tbl.getSelectedColumn());
            System.out.println(selectedCellValue);
        }
        @Override
        public void mouseExited(MouseEvent e) {
        }
        @Override
        public void mouseEntered(MouseEvent e) {
        }
        @Override
        public void mouseClicked(MouseEvent e) {
        }
    });

This is a self-promotional answer, but I spent a few months researching this and presented the results at jQuery Conference San Francisco 2012.

Here is a free video of the talk:

Here is how to do it using TCP IP protocol :

// Printer IP Address and communication port
    string ipAddress = "10.3.14.42";
   int port = 9100;

// ZPL Command(s)
   string ZPLString =
    "^XA" +
    "^FO50,50" +
    "^A0N50,50" +
    "^FDHello, World!^FS" +
    "^XZ";

   try
   {
    // Open connection
    System.Net.Sockets.TcpClient client = new System.Net.Sockets.TcpClient();
    client.Connect(ipAddress, port);

    // Write ZPL String to connection
    System.IO.StreamWriter writer =
    new System.IO.StreamWriter(client.GetStream());
    writer.Write(ZPLString);
    writer.Flush();

    // Close Connection
    writer.Close();
    client.Close();
}
catch (Exception ex)
{
    // Catch Exception

Here is what you want to put in the project's Post-build event command line:

copy /Y "$(TargetDir)$(ProjectName).dll" "$(SolutionDir)lib\$(ProjectName).dll"

EDIT: Or if your target name is different than the Project Name.

copy /Y "$(TargetDir)$(TargetName).dll" "$(SolutionDir)lib\$(TargetName).dll"

try :is selector

$("#deliveryNext").is(":disabled")

Another option may be this John Resig remove method. can better fit what you need. if you know the index in the array.

For anyone reading this and using Postgres.app, you may need host: localhost in your database.yml. http://postgresapp.com/documentation#toc_3

Yes, take a look at this thread which talks about the differences between platforms.

How to detect right-click event for Mac OS

BUTTON3 is the same across all platforms, being equal to the right mouse button. BUTTON2 is simply ignored if the middle button does not exist.

I did not get it. I had a similar problem but in my nav bar.

What I was doing is I kept my navBar code in this way: nav>div.navlinks>ul>li*3>a

In order to put hover effects on a I positioned a to relative and designed a::before and a::after then i put a gray background on before and after elements and kept hover effects in such way that as one hovers on <a> they will pop from outside a to fill <a>.

The problem is that the overflow hidden is not working on <a>.

What i discovered is if i removed <li> and simply put <a> without <ul> and <li> then it worked.

What may be the problem?

str.split(' ').join('§ §').split('§');

Obfuscation can never really work. For anyone who really wants to get at your code, it's just a speed bump. Worse, it keeps your users from fixing bugs (and shipping the fixes back to you), and makes it harder for you to diagnose problems in the field. Its a waste of your time and money.

Talk to a lawyer about intellectual property law and what your legal options are. "Open Source" does not mean "people can read the source". Instead, Open Source is a particular licensing model granting permission to freely use and modify your code. If you don't grant such a license then people copying your code are in violation and (in most of the world) you have legal options to stop them.

The only way you can really protect your code is to not ship it. Move the important code server-side and have your public Javascript code do Ajax calls to it.

See my full answer about obfuscators here.

You can use a regular expresion to for example replace all non-alphanumeric characters with commas:

s = Regex.Replace(s, "[^0-9A-Za-z]+", ",");

Note: The + after the set will make it replace each group of non-alphanumeric characters with a comma. If you want to replace each character with a comma, just remove the +.

You need this include:

#include <sstream>

None of these were working for me, couldn't delete or disconnect current users. Also couldn't see any active connections to the DB. Restarting SQL Server (Right click and select Restart) allowed me to do it.

Something no one seems to have noted yet is readability. Having…

CONVERT(SomeType,
    SomeReallyLongExpression
    + ThatMayEvenSpan
    + MultipleLines
    )

…may be easier to understand than…

CAST(SomeReallyLongExpression
    + ThatMayEvenSpan
    + MultipleLines
    AS SomeType
    )

Your code works fine for me. It replaced the text in the file as expected and didn't append.

If you wanted to append, you set the second parameter in

new FileWriter(fnew,false);

to true;

Probably not the most efficient, but think it's a neat way to do it.

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true"));
        Console.WriteLine(CountAllTheTimesThisStringAppearsInThatString("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "false"));

    }

    static Int32 CountAllTheTimesThisStringAppearsInThatString(string orig, string find)
    {
        var s2 = orig.Replace(find,"");
        return (orig.Length - s2.Length) / find.Length;
    }
}

EDIT: I found this link. Hope it helps. http://viralpatel.net/blogs/2011/02/clearable-textbox-jquery.html

You have mentioned you want it on the right of the input text. So, the best way would be to create an image next to the input box. If you are looking something inside the box, you can use background image but you may not be able to write a script to clear the box.

So, insert and image and write a JavaScript code to clear the textbox.

Use the std::vector class from the standard library.

Pattern are always preferable for restriction, try oninput and min occur 1 for inputting only numbers from 1 onwards

<input type="text" min="1" oninput="this.value=this.value.replace(/[^0-9]/g,'');"
                                value=${var} >

I dont't know whether it was best to answer this as an answer or as a comment. I opted for the first option.

Regarding the poing PART IV: Forgotten Password Functionality in the first answer, I would make a point about Timing Attacks.

In the Remember your password forms, an attacker could potentially check a full list of emails and detect which are registered to the system (see link below).

Regarding the Forgotten Password Form, I would add that it is a good idea to equal times between successful and unsucessful queries with some delay function.

https://crypto.stanford.edu/~dabo/papers/webtiming.pdf

Given this example url:

http://www.example.com/some-dir/yourpage.php?q=bogus&n=10

$_SERVER['REQUEST_URI'] will give you:

/some-dir/yourpage.php?q=bogus&n=10

Whereas $_GET['q'] will give you:

bogus

In other words, $_SERVER['REQUEST_URI'] will hold the full request path including the querystring. And $_GET['q'] will give you the value of parameter q in the querystring.

If you're putting a <meta> tag in your css files, you're doing something wrong. The <meta> tag belongs in your html files, and tells the browser how the html is encoded, it doesn't say anything about the css, which is a separate file. You could conceivably have completely different encodings for your html and css, although I can't imagine this would be a good idea.

Some people using Lazy loading are going to stumble across this page.

Here is what I did to fix sharing a directive.

1. create a new shared module

shared.module.ts

import { NgModule, Directive,OnInit, EventEmitter, Output, OnDestroy, Input,ElementRef,Renderer } from '@angular/core';
import { CommonModule } from '@angular/common';

import { SortDirective } from './sort-directive';

@NgModule({
  imports: [
  ],
  declarations: [
  SortDirective
  ],
  exports: [
    SortDirective
  ]
})

export class SharedModule { }

Then in app.module and your other module(s)

import {SharedModule} from '../directives/shared.module'
...

@NgModule({
   imports: [
       SharedModule
       ....
       ....
 ]
})
export class WhateverModule { }

In drawable I use this xml code to define the border and background:

<shape xmlns:android="http://schemas.android.com/apk/res/android"> 
  <stroke android:width="4dp" android:color="#D8FDFB" /> 
  <padding android:left="7dp" android:top="7dp" 
    android:right="7dp" android:bottom="7dp" /> 
  <corners android:radius="4dp" /> 
  <solid android:color="#f0600000"/> 
</shape> 

if you need a quick test on your query, this works great for me

echo $this->db->last_query(); die;

To optimize the Java code runtime, int primitive type(s) has been added including float, bool etc. but they come along with there wrapper classes so that if needed you can convert and use them as standard Java object along with many utility that comes as their member functions (such as Integer.parseInt("1")).

The best way is to use fixtures.

Note: Keep in mind that fixtures do direct inserts and don't use your model so if you have callbacks that populate data you will need to find a workaround.

This is useful when you have your own origin which is not upstream. In other words, you might have your own origin repo that you do development and local changes in and then occasionally merge upstream changes. The difference between your example and the highlighted text is that your example assumes you're working with a clone of the upstream repo directly. The highlighted text assumes you're working on a clone of your own repo that was, presumably, originally a clone of upstream.

Always use library. Never use require.

In a nutshell, this is because, when using require, your code might yield different, erroneous results, without signalling an error. This is rare but not hypothetical! Consider this code, which yields different results depending on whether {dplyr} can be loaded:

require(dplyr)

x = data.frame(y = seq(100))
y = 1
filter(x, y == 1)

This can lead to subtly wrong results. Using library instead of require throws an error here, signalling clearly that something is wrong. This is good.

It also makes debugging all other failures more difficult: If you require a package at the start of your script and use its exports in line 500, you’ll get an error message “object ‘foo’ not found” in line 500, rather than an error “there is no package called ‘bla’”.

The only acceptable use case of require is when its return value is immediately checked, as some of the other answers show. This is a fairly common pattern but even in these cases it is better (and recommended, see below) to instead separate the existence check and the loading of the package. That is: use requireNamespace instead of require in these cases.

More technically, require actually calls library internally (if the package wasn’t already attached — require thus performs a redundant check, because library also checks whether the package was already loaded). Here’s a simplified implementation of require to illustrate what it does:

require = function (package) {
    already_attached = paste('package:', package) %in% search()
    if (already_attached) return(TRUE)
    maybe_error = try(library(package, character.only = TRUE)) 
    success = ! inherits(maybe_error, 'try-error')
    if (! success) cat("Failed")
    success
}

Experienced R developers agree:

Yihui Xie, author of {knitr}, {bookdown} and many other packages says:

Ladies and gentlemen, I've said this before: require() is the wrong way to load an R package; use library() instead

Hadley Wickham, author of more popular R packages than anybody else, says

Use library(x) in data analysis scripts. […] You never need to use require() (requireNamespace() is almost always better)

Forge's SHA-256 implementation is fast and reliable.

To run tests on several SHA-256 JavaScript implementations, go to http://brillout.github.io/test-javascript-hash-implementations/.

The results on my machine suggests forge to be the fastest implementation and also considerably faster than the Stanford Javascript Crypto Library (sjcl) mentioned in the accepted answer.

Forge is 256 KB big, but extracting the SHA-256 related code reduces the size to 4.5 KB, see https://github.com/brillout/forge-sha256

In Ubuntu

Step 1:

sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

Step 2: Go to last line and add the following

sql_mode = ""

Step 3: Save

Step 4: Restart mysql server.

You can use lambda expression since Java 8.

The following code will print 10, the larger.

// There is overflow problem when using simple lambda as comparator, as pointed out by ???? ?????.
// PriorityQueue<Integer> pq = new PriorityQueue<>((x, y) -> y - x);

PriorityQueue<Integer> pq =new PriorityQueue<>((x, y) -> Integer.compare(y, x));

pq.add(10);
pq.add(5);
System.out.println(pq.peek());

The lambda function will take two Integers as input parameters, subtract them from each other, and return the arithmetic result. The lambda function implements the Functional Interface, Comparator<T>. (This is used in place, as opposed to an anonymous class or a discrete implementation.)

You need to add an event, before call your handleFunction like this:

function SingInContainer() {
..
..
handleClose = () => {
}

return (
    <SnackBar
        open={open}
        handleClose={() => handleClose}
        variant={variant}
        message={message}
        />
    <SignInForm/>
)

}

To open docs automatically in Chrome without them being saved;

1. Go to the the three vertical dots on your top far right corner in Chrome.

2. Scroll down to Settings and click.

3. Scroll down to Show advance settings...

4. Scroll down to Downloads under Download location: click the Change button and chose tmp folder. Then just close the screen.

5. Click on any attachments and a small box to the left will appear, it should automatically open if you click on it.

6. When the bottom left box appears it will contain an arrow; click on it and choose the option "Always open files of this type". Going forward it will open the file instantly instead of the small box appearing to the left and you having to click on it to open. You will have to do it just once for various files such PDF, Excel 2010, Excel 2013 Word, ect.

I think the problem that all the solution listed doesn't work, is intrinsic in the nature of http service, the every request established is with a different client and the response need to be processed in a different context, every request must fork a new instance of response...

The current solution I think is the -e of netcat but I don't know why doesn't work... maybe is my nc version that I test on openwrt...

with socat it works....

I try this https://github.com/avleen/bashttpd

and it works, but I must run the shell script with this command.

socat tcp-l:80,reuseaddr,fork EXEC:bashttpd &

The socat and netcat samples on github doesn't works for me, but the socat that I used works.

system("timeout /t 60"); // waits 60s. this is only for windows vista,7,8
system("ping -n 60 127.0.0.1 >nul"); // waits 60s. for all windows

This may be possible by using the refs attribute.

In the example of wanting to to reach a <div> what you would want to do is use is <div ref="myExample">. Then you would be able to get that DOM node by using React.findDOMNode(this.refs.myExample).

From there getting the correct DOM node of each child may be as simple as mapping over this.refs.myExample.children(I haven't tested that yet) but you'll at least be able to grab any specific mounted child node by using the ref attribute.

Here's the official react documentation on refs for more info.

For me (react-router v4, react v16) the problem was that I had the navigation component all right:

import { Link, withRouter } from 'react-router-dom'

class MainMenu extends Component {

  render() {
    return (
            ...
            <NavLink to="/contact">Contact</NavLink>
            ...
    );
  }
}

export default withRouter(MainMenu);

Both using either

to="/contact" 

or

OnClick={() => this.props.history.push('/contact')}; 

The behavior was still the same - the URL in browser changed but wrong components were rendered, the router was called with the same old URL.

The culprit was in the router definition. I had to move the MainMenu component as a child of the Router component!

// wrong placement of the component that calls the router
<MainMenu history={this.props.history} />
<Router>
   <div>
     // this is the right place for the component!
     <MainMenu history={this.props.history} />
     <Route path="/" exact component={MainPage} />
     <Route path="/contact/" component={MainPage} />
   </div>
</Router>

& is bitwise. && is logical.

& evaluates both sides of the operation.
&& evaluates the left side of the operation, if it's true, it continues and evaluates the right side.

You would because defining an IList or an ICollection would open up for other implementations of your interfaces.

You might want to have an IOrderRepository that defines a collection of orders in either a IList or ICollection. You could then have different kinds of implementations to provide a list of orders as long as they conform to "rules" defined by your IList or ICollection.

You can't find a consistent reference because it seems to go by at least six different names!

• Card Security Code
• Card Verification Value (CVV or CV2)
• Card Verification Value Code (CVVC)
• Card Verification Code (CVC)
• Verification Code (V-Code or V Code)
• Card Code Verification (CCV)

The following is also working for me:

ssh <user>@<host>  "cat <filepath>"|pbcopy 

One main reason we went with Workstation over Player at my job is because we need to run VMs that use a physical disk as their hard drive instead of a virtual disk. Workstation supports using physical disks while Player does not.

adding org.junit.platform to your pom and build it. Next, you need to go to "Run Configuration" of your TEST FILE and add JUNIT in the classpath, APPLY->RUN will resolve the issue.

You're using span6 and span2. Both of these classes are "float:left" meaning, if possible they will always try to sit next to each other. Twitter bootstrap is based on a 12 grid system. So you should generally always get the span**#** to add up to 12.

E.g.: span4 + span4 + span4 OR span6 + span6 OR span4 + span3 + span5.

To force a span down though, without listening to the previous float you can use twitter bootstraps clearfix class. To do this, your code should look like this:

<ul class="nav nav-tabs span2">
  <li><a href="./index.html"><i class="icon-black icon-music"></i></a></li>
  <li><a href="./about.html"><i class="icon-black icon-eye-open"></i></a></li>
  <li><a href="./team.html"><i class="icon-black icon-user"></i></a></li>
  <li><a href="./contact.html"><i class="icon-black icon-envelope"></i></a></li>
</ul>
<!-- Notice this following line -->
<div class="clearfix"></div>
<div class="well span6">
  <h3>I wish this appeared on the next line without having to gratuitously use BR!</h3>
</div>

To find case-insensitive literals string:

Using regex (recommended)

db.collection.find({
    name: {
        $regex: new RegExp('^' + name.replace(/[-\/\\^$*+?.()|[\]{}]/g, '\\$&') + '$', 'i')
    }
});

Using lower-case index (faster)

db.collection.find({
    name_lower: name.toLowerCase()
});

Regular expressions are slower than literal string matching. However, an additional lowercase field will increase your code complexity. When in doubt, use regular expressions. I would suggest to only use an explicitly lower-case field if it can replace your field, that is, you don't care about the case in the first place.

Note that you will need to escape the name prior to regex. If you want user-input wildcards, prefer appending .replace(/%/g, '.*') after escaping so that you can match "a%" to find all names starting with 'a'.

Regarding a previous answer

if (B) y = offset + slope*x

then (C) offset = y/(slope*x) is wrong

(C) should be:

offset = y-(slope*x)

See: http://zedgraph.org/wiki/index.php?title=Trend

I suggest you take a look at the HTML that the code spits out and see if theres a way to uniquely identify one (or both) of the buttons (possibly the id or name attributes), then use jQuery to select that item and apply a css class to it.

<button style="position: absolute; left: 20%; right: 20%; bottom: 5%;"> Button </button>

I am not sure about Python but most languages have push/append function for arrays.

Kind of a messy workaround, but assignment in lambdas is illegal anyway, so it doesn't really matter. You can use the builtin exec() function to run assignment from inside the lambda, such as this example:

>>> val
Traceback (most recent call last):
  File "<pyshell#31>", line 1, in <module>
    val
NameError: name 'val' is not defined
>>> d = lambda: exec('val=True', globals())
>>> d()
>>> val
True

To answer my own question, this functionality has been added to pandas in the meantime. Starting from pandas 0.15.0, you can use tz_localize(None) to remove the timezone resulting in local time.
See the whatsnew entry: http://pandas.pydata.org/pandas-docs/stable/whatsnew.html#timezone-handling-improvements

So with my example from above:

In [4]: t = pd.date_range(start="2013-05-18 12:00:00", periods=2, freq='H',
                          tz= "Europe/Brussels")

In [5]: t
Out[5]: DatetimeIndex(['2013-05-18 12:00:00+02:00', '2013-05-18 13:00:00+02:00'],
                       dtype='datetime64[ns, Europe/Brussels]', freq='H')

using tz_localize(None) removes the timezone information resulting in naive local time:

In [6]: t.tz_localize(None)
Out[6]: DatetimeIndex(['2013-05-18 12:00:00', '2013-05-18 13:00:00'], 
                      dtype='datetime64[ns]', freq='H')

Further, you can also use tz_convert(None) to remove the timezone information but converting to UTC, so yielding naive UTC time:

In [7]: t.tz_convert(None)
Out[7]: DatetimeIndex(['2013-05-18 10:00:00', '2013-05-18 11:00:00'], 
                      dtype='datetime64[ns]', freq='H')

This is much more performant than the datetime.replace solution:

In [31]: t = pd.date_range(start="2013-05-18 12:00:00", periods=10000, freq='H',
                           tz="Europe/Brussels")

In [32]: %timeit t.tz_localize(None)
1000 loops, best of 3: 233 µs per loop

In [33]: %timeit pd.DatetimeIndex([i.replace(tzinfo=None) for i in t])
10 loops, best of 3: 99.7 ms per loop

I fixed this problem employing the two procedures of :

1. In Eclipse->'Project' menu -> 'Java Compiler' -> set 'Compiler compliance level' = 1.6 check on 'Use default compliance settings' Set 'Generated .class compatibility' = 1.6 Set 'Source compatibilty' = 1.6

2. Then go to 'Windows' menu --> 'Preferences' -->'Java' , expand 'Java' --> 'Compiler' -->Set 'Compiler compliance level' = 1.6

Hint: Source compatibility must be equal to or less than compliance level.

A concrete example of overhead is the difference between a "local" procedure call and a "remote" procedure call.

For example, with classic RPC (and many other remote frameworks, like EJB), a function or method call looks the same to a coder whether its a local, in memory call, or a distributed, network call.

For example:

service.function(param1, param2);

Is that a normal method, or a remote method? From what you see here you can't tell.

But you can imagine that the difference in execution times between the two calls are dramatic.

So, while the core implementation will "cost the same", the "overhead" involved is quite different.

I had this problem (colons in the target name) because I had -n in my GREP_OPTIONS environment variable. Apparently, this caused configure to generate the Makefile incorrectly.

You can use one of the moment plugin -> moment-range to deal with date range:

var startDate = new Date(2013, 1, 12)
  , endDate   = new Date(2013, 1, 15)
  , date  = new Date(2013, 2, 15)

If you want to just compare dates,

yourdatetime.date() < datetime.today().date()

Or, obviously,

yourdatetime.date() == datetime.today().date()

If you want to check that they're the same date.

The documentation is usually helpful. It is also usually the first google result for python thing_i_have_a_question_about. Unless your question is about a function/module named "snake".

Basically, the datetime module has three types for storing a point in time:

• date for year, month, day of month
• time for hours, minutes, seconds, microseconds, time zone info
• datetime combines date and time. It has the methods date() and time() to get the corresponding date and time objects, and there's a handy combine function to combine date and time into a datetime.

I adapted a script originally written by Narayana Vyas Kondreddi in 2002. I changed the where clause to check text/ntext fields as well, by using patindex rather than like. I also changed the results table slightly. Unreasonably, I changed variable names, and aligned as I prefer (no disrespect to Mr. Kondretti). The user may want to change the data types searched. I used a global table to allow querying mid-processing, but a permanent table might be a smarter way to go.

/* original script by Narayana Vyas Kondreddi, 2002 */

Another method if you're stuck on <2.6, you don't have numpy, and you don't have IEEE 754 support:

def isNaN(x):
    return str(x) == str(1e400*0)

I've had the same problem you describe. The web site I'm building can be accessed from a mobile phone and from the browser so I need an api to allow users to signup, login and do some specific tasks. Furthermore, I need to support scalability, the same code running on different processes/machines.

Because users can CREATE resources (aka POST/PUT actions) you need to secure your api. You can use oauth or you can build your own solution but keep in mind that all the solutions can be broken if the password it's really easy to discover. The basic idea is to authenticate users using the username, password and a token, aka the apitoken. This apitoken can be generated using node-uuid and the password can be hashed using pbkdf2

Then, you need to save the session somewhere. If you save it in memory in a plain object, if you kill the server and reboot it again the session will be destroyed. Also, this is not scalable. If you use haproxy to load balance between machines or if you simply use workers, this session state will be stored in a single process so if the same user is redirected to another process/machine it will need to authenticate again. Therefore you need to store the session in a common place. This is typically done using redis.

When the user is authenticated (username+password+apitoken) generate another token for the session, aka accesstoken. Again, with node-uuid. Send to the user the accesstoken and the userid. The userid (key) and the accesstoken (value) are stored in redis with and expire time, e.g. 1h.

Now, every time the user does any operation using the rest api it will need to send the userid and the accesstoken.

If you allow the users to signup using the rest api, you'll need to create an admin account with an admin apitoken and store them in the mobile app (encrypt username+password+apitoken) because new users won't have an apitoken when they sign up.

The web also uses this api but you don't need to use apitokens. You can use express with a redis store or use the same technique described above but bypassing the apitoken check and returning to the user the userid+accesstoken in a cookie.

If you have private areas compare the username with the allowed users when they authenticate. You can also apply roles to the users.

Summary:

An alternative without apitoken would be to use HTTPS and to send the username and password in the Authorization header and cache the username in redis.

The error message is confusing for one big reason:

Primitive type names are not reserved in PHP

The following are all valid class declarations:

class string { }
class int { }
class float { }
class double { }

My mistake was in thinking that the error message was referring solely to the string primitive type - the word 'instance' should have given me pause. An example to illustrate further:

class string { }
$n = 1234;
$s1 = (string)$n;
$s2 = new string();
$a = array('no', 'yes');
printf("\$s1 - primitive string? %s - string instance? %s\n",
        $a[is_string($s1)], $a[is_a($s1, 'string')]);
printf("\$s2 - primitive string? %s - string instance? %s\n",
        $a[is_string($s2)], $a[is_a($s2, 'string')]);

Output:

$s1 - primitive string? yes - string instance? no

$s2 - primitive string? no - string instance? yes

In PHP it's possible for a string to be a string except when it's actually a string. As with any language that uses implicit type conversion, context is everything.

Specific use case for emplace_back: If you need to create a temporary object which will then be pushed into a container, use emplace_back instead of push_back. It will create the object in-place within the container.

Notes:

1. push_back in the above case will create a temporary object and move it into the container. However, in-place construction used for emplace_back would be more performant than constructing and then moving the object (which generally involves some copying).
2. In general, you can use emplace_back instead of push_back in all the cases without much issue. (See exceptions)

If you are splitting from Linux, you can still reassemble in Windows.

copy /b file1 + file2 + file3 + file4 filetogether

Maybe something like this:

yourformName.YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);

Or if you are in the same class as the form then simply do this:

YourLabel.Font = new Font("Arial", 24,FontStyle.Bold);

The constructor takes diffrent parameters (so pick your poison). Like this:

Font(Font, FontStyle)   
Font(FontFamily, Single)
Font(String, Single)
Font(FontFamily, Single, FontStyle)
Font(FontFamily, Single, GraphicsUnit)
Font(String, Single, FontStyle)
Font(String, Single, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit)
Font(String, Single, FontStyle, GraphicsUnit)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte)
Font(String, Single, FontStyle, GraphicsUnit, Byte)
Font(FontFamily, Single, FontStyle, GraphicsUnit, Byte, Boolean)
Font(String, Single, FontStyle, GraphicsUnit, Byte, Boolean)

You should use absolute path when setting error_log variable in your php.ini file, otherwise, error logs will be stored according to your relative path.

error_log = /var/log/php.errors

Other solution would be writing simple script which would list all error logs files from directory tree.

Arduino doesn't run either C or C++. It runs machine code compiled from either C, C++ or any other language that has a compiler for the Arduino instruction set.

C being a subset of C++, if Arduino can "run" C++ then it can "run" C.

If you don't already know C nor C++, you should probably start with C, just to get used to the whole "pointer" thing. You'll lose all the object inheritance capabilities though.

There are two ways to write case statements, you seem to be using a combination of the two

case a.updatedDate
    when 1760 then 'Entered on' + a.updatedDate
    when 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

or

case 
    when a.updatedDate = 1760 then 'Entered on' + a.updatedDate
    when a.updatedDate = 1710 then 'Viewed on' + a.updatedDate
    else 'Last Updated on' + a.updateDate
end

are equivalent. They may not work because you may need to convert date types to varchars to append them to other varchars.

Use a regex: .

Match m = Regex.Match(text, @"(.+? .+?) ");
if (m.Success) {
    do_something_with(m.Groups[1].Value);
}

In general, i agree with above answers that recommend to add maven dependency, but i prefer following solution.

Add a dependency with API classes for full JavaEE profile:

<properties>
    <javaee-api.version>7.0</javaee-api.version>
    <hibernate-entitymanager.version>5.1.3.Final</hibernate-entitymanager.version>
</properties>

<depencies>
    <dependency>
        <groupId>javax</groupId>
        <artifactId>javaee-api</artifactId>
        <version>${javaee-api.version}</version>
        <scope>provided</scope>
    </dependency>
</dependencies>

Also add dependency with particular JPA provider like antonycc suggested:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>${hibernate-entitymanager.version}</version>
</dependency>

Note <scope>provided</scope> in API dependency section: this means that corresponding jar will not be exported into artifact's lib/, but will be provided by application server. Make sure your application server implements specified version of JavaEE API.

You can use isin method:

In [1]: df = pd.DataFrame({'A': [5,6,3,4], 'B': [1,2,3,5]})

In [2]: df
Out[2]:
   A  B
0  5  1
1  6  2
2  3  3
3  4  5

In [3]: df[df['A'].isin([3, 6])]
Out[3]:
   A  B
1  6  2
2  3  3

And to get the opposite use ~:

In [4]: df[~df['A'].isin([3, 6])]
Out[4]:
   A  B
0  5  1
3  4  5

There are plenty of forum questions in that subject.

I have found the answer in windows api. You don't need to restart the computer after uninstalling the service. You have to call:

BOOL WINAPI CloseServiceHandle(
  SC_HANDLE hSCObject
);

That closes the handle of the service. On windows 7 it solved my problem. I do:

• stop service
• close handle
• uninstall service
• wait 3 sec
• copy new exe to the directory
• install the service
• start service
• close handle

In a hacky way it can be done for channels which one attempts to write to by recovering the raised panic. But you cannot check if a read channel is closed without reading from it.

Either you will

• eventually read the "true" value from it (v <- c)
• read the "true" value and 'not closed' indicator (v, ok <- c)
• read a zero value and the 'closed' indicator (v, ok <- c)
• will block in the channel read forever (v <- c)

Only the last one technically doesn't read from the channel, but that's of little use.

declare @T table(Roles xml)

insert into @T values
('<root>
   <role>Alpha</role>
   <role>Beta</role>
   <role>Gamma</role>
</root>')

declare @Role varchar(10)

set @Role = 'Beta'

select Roles
from @T
where Roles.exist('/root/role/text()[. = sql:variable("@Role")]') = 1

If you want the query to work as where col like '%Beta%' you can use contains

declare @T table(Roles xml)

insert into @T values
('<root>
   <role>Alpha</role>
   <role>Beta</role>
   <role>Gamma</role>
</root>')

declare @Role varchar(10)

set @Role = 'et'

select Roles
from @T
where Roles.exist('/root/role/text()[contains(., sql:variable("@Role"))]') = 1

Another way to do this, which I personally find slightly more convenient and intuitive (without having to remember the --args parameter), is to compile normally, and use r arg1 arg2 arg3 directly from within gdb, like so:

$ gcc -g *.c *.h
$ gdb ./a.out
(gdb) r arg1 arg2 arg3

Apache's errorlog will explain why you get a permission denied. Also, serverfault.com is a better forum for a question like this.

If the error log simply says "permission denied", su to the user that the webserver is running as and try to read from the file in question. So for example:

sudo -s
su - nobody
cd /
cd /home
cd user
cd xxx
cat index.html

See if one of those gives you the "permission denied" error.

Douglas Crockford has some very good explanations of inheritance in JavaScript:

1. prototypal inheritance: the 'natural' way to do things in JavaScript
2. classical inheritance: closer to what you find in most OO languages, but kind of runs against the grain of JavaScript

I find an library socket.io to test asynchronous logic. It looks simple and brief way using LinkedBlockingQueue. Here is example:

    @Test(timeout = TIMEOUT)
public void message() throws URISyntaxException, InterruptedException {
    final BlockingQueue<Object> values = new LinkedBlockingQueue<Object>();

    socket = client();
    socket.on(Socket.EVENT_CONNECT, new Emitter.Listener() {
        @Override
        public void call(Object... objects) {
            socket.send("foo", "bar");
        }
    }).on(Socket.EVENT_MESSAGE, new Emitter.Listener() {
        @Override
        public void call(Object... args) {
            values.offer(args);
        }
    });
    socket.connect();

    assertThat((Object[])values.take(), is(new Object[] {"hello client"}));
    assertThat((Object[])values.take(), is(new Object[] {"foo", "bar"}));
    socket.disconnect();
}

Using LinkedBlockingQueue take API to block until to get result just like synchronous way. And set timeout to avoid assuming too much time to wait the result.

If you know which dict in the list has the key you're looking for, then you already have the solution (as presented by Matt and Ignacio). However, if you don't know which dict has this key, then you could do this:

def getValueOf(k, L):
    for d in L:
        if k in d:
            return d[k]

You should use the .offsetWidth and .offsetHeight properties. Note they belong to the element, not .style.

var width = document.getElementById('foo').offsetWidth;

Function .getBoundingClientRect() returns dimensions and location of element as floating-point numbers after performing CSS transforms.

> console.log(document.getElementById('id').getBoundingClientRect())
DOMRect {
    bottom: 177,
    height: 54.7,
    left: 278.5,?
    right: 909.5,
    top: 122.3,
    width: 631,
    x: 278.5,
    y: 122.3,
}

Actually, your last example:

<div data-foobar='{"foo":"bar"}'></div>

seems to be working well (see http://jsfiddle.net/GlauberRocha/Q6kKU/).

The nice thing is that the string in the data- attribute is automatically converted to a JavaScript object. I don't see any drawback in this approach, on the contrary! One attribute is sufficient to store a whole set of data, ready to use in JavaScript through object properties.

(Note: for the data- attributes to be automatically given the type Object rather than String, you must be careful to write valid JSON, in particular to enclose the key names in double quotes).

See ?merge:

the name "row.names" or the number 0 specifies the row names.

Example:

R> de <- merge(d, e, by=0, all=TRUE)  # merge by row names (by=0 or by="row.names")
R> de[is.na(de)] <- 0                 # replace NA values
R> de
  Row.names   a   b   c   d   e   f   g   h   i  j  k  l  m  n  o  p  q  r  s
1         1 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10 11 12 13 14 15 16 17 18 19
2         2 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9  1  0  0  0  0  0  0  0  0  0
3         3 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0  0 21 22 23 24 25 26 27 28 29
   t
1 20
2  0
3 30

console.log(document.getElementById('xx') ) evaluates to null.

document.getElementById('xx') !=null evaluates to false

You should use document.getElementById('xx') !== null as it is a stronger equality check.

A Ternary is not a good solution for what you want. It will not be readable in your code, and there are much better solutions available.

Why not use an array lookup "map" or "dictionary", like so:

$vocations = array(
    1 => "Sorcerer",
    2 => "Druid",
    3 => "Paladin",
    ...
);

echo $vocations[$result->vocation];

A ternary for this application would end up looking like this:

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Why is this bad? Because - as a single long line, you would get no valid debugging information if something were to go wrong here, the length makes it difficult to read, plus the nesting of the multiple ternaries just feels odd.

A Standard Ternary is simple, easy to read, and would look like this:

$value = ($condition) ? 'Truthy Value' : 'Falsey Value';

or

echo ($some_condition) ? 'The condition is true!' : 'The condition is false.';

A ternary is really just a convenient / shorter way to write a simple if else statement. The above sample ternary is the same as:

if ($some_condition) {
    echo 'The condition is true!';
} else {
    echo 'The condition is false!';
}

However, a ternary for a complex logic quickly becomes unreadable, and is no longer worth the brevity.

echo($result->group_id == 1 ? "Player" : ($result->group_id == 2 ? "Gamemaster" : ($result->group_id == 3 ? "God" : "unknown")));

Even with some attentive formatting to spread it over multiple lines, it's not very clear:

echo($result->group_id == 1 
    ? "Player" 
    : ($result->group_id == 2 
        ? "Gamemaster" 
        : ($result->group_id == 3 
            ? "God" 
            : "unknown")));

I'm most definitely hitting this issue with attribute routing. The issue was fixed as of 5.0.0-rtm-130905. But still, you can try out the nightly builds which will most certainly have the fix.

To add nightlies to your NuGet package source, go to Tools -> Library Package Manager -> Package Manager Settings and add the following URL under Package Sources: http://myget.org/F/aspnetwebstacknightly

I have made a refined version of the proposed solution that is a simpler and parametrises the firstDayOfWeek:

public static DateTime GetFirstDayOfWeek(int year, int week, DayOfWeek firstDayOfWeek)
{
    return GetWeek1Day1(year, firstDayOfWeek).AddDays(7 * (week - 1));
}

public static DateTime GetWeek1Day1(int year, DayOfWeek firstDayOfWeek)
{
    DateTime date = new DateTime(year, 1, 1);

    // Move towards firstDayOfWeek
    date = date.AddDays(firstDayOfWeek - date.DayOfWeek);

    // Either 1 or 52 or 53
    int weekOfYear = CultureInfo.CurrentCulture.Calendar.GetWeekOfYear(date, CalendarWeekRule.FirstFullWeek, firstDayOfWeek);

    // Move forwards 1 week if week is 52 or 53
    date = date.AddDays(7 * System.Math.Sign(weekOfYear - 1));

    return date;
}

use the include is the easiest way as per

Use the nowrap style:

<td style="white-space:nowrap;">...</td>

It's CSS!

DECIMAL_DIG from <float.h> should give at least a reasonable approximation of that. Since that deals with decimal digits, and it's really stored in binary, you can probably store something a little larger without losing precision, but exactly how much is hard to say. I suppose you should be able to figure it out from FLT_RADIX and DBL_MANT_DIG, but I'm not sure I'd completely trust the result.

If you throw the exception, the method execution will stop and the exception is thrown to the caller method. throw always interrupt the execution flow of the current method. a try/catch block is something you could write when you call a method that may throw an exception, but throwing an exception just means that method execution is terminated due to an abnormal condition, and the exception notifies the caller method of that condition.

Find this tutorial about exception and how they work - http://docs.oracle.com/javase/tutorial/essential/exceptions/

You can simply right-click and save the blob as mp4.

When I was playing around with browser based video/audio recording the output blob was available to download directly.

Subscribing to # gives you a subscription to everything except for topics that start with a $ (these are normally control topics anyway).

It is better to know what you are subscribing to first though, of course, and note that some broker configurations may disallow subscribing to # explicitly.

I don't know why everyone forgot to mention the amazing capability of sets in python. You can simply cast your list into a set and then remove whatever you want to remove in a simple expression like so:

>>> item_list = ['item', 5, 'foo', 3.14, True]
>>> item_list = set(item_list) - {'item', 5}
>>> item_list
{True, 3.14, 'foo'}
>>> # you can cast it again in a list-from like so
>>> item_list = list(item_list)
>>> item_list
[True, 3.14, 'foo']

if ( $( "#myDiv" ).length ) {
    // if ( "#myDiv" ) is exist this will perform
    $( "#myDiv" ).show();

}

Another shorthand way:

    $( "#myDiv" ).length && $( "#myDiv" ).show();

You can consider a trait as an automated "copy-paste" of code, basically.

Using traits is dangerous since there is no mean to know what it does before execution.

However, traits are more flexible because of their lack of limitations such as inheritance.

Traits can be useful to inject a method which checks something into a class, for example, the existence of another method or attribute. A nice article on that (but in French, sorry).

For French-reading people who can get it, the GNU/Linux Magazine HS 54 has an article on this subject.

According to the book PHP and MySQL for Dynamic Web Sites (4th edition)

Example:

$r = mysqli_query($dbc, $q);

For simple queries like INSERT, UPDATE, DELETE, etc. (which do not return records), the $r variable—short for result—will be either TRUE or FALSE, depending upon whether the query executed successfully.

Keep in mind that “executed successfully” means that it ran without error; it doesn’t mean that the query’s execution necessarily had the desired result; you’ll need to test for that.

Then how to test?

While the mysqli_num_rows() function will return the number of rows generated by a SELECT query, mysqli_affected_rows() returns the number of rows affected by an INSERT, UPDATE, or DELETE query. It’s used like so:

$num = mysqli_affected_rows($dbc);

Unlike mysqli_num_rows(), the one argument the function takes is the database connection ($dbc), not the results of the previous query ($r).

Use the rtrim function:

rtrim($my_string, ',');

The Second parameter indicates the character to be deleted.

You can call tail +[line number] [file] and pipe it to grep -n which shows the line number:

tail +[line number] [file] | grep -n /regex/

The only problem with this method is the line numbers reported by grep -n will be [line number] - 1 less than the actual line number in [file].

Here's a bit of an improvement on the excellent answer provided by Mathew Wolf. This one appends the main container as a style tag to the head element and appends each new class to that style tag. a little more concise and I find it works well.

function changeCss(className, classValue) {
    var cssMainContainer = $('#css-modifier-container');

    if (cssMainContainer.length == 0) {
        var cssMainContainer = $('<style id="css-modifier-container"></style>');
        cssMainContainer.appendTo($('head'));
    }

    cssMainContainer.append(className + " {" + classValue + "}\n");
}

By using drop_duplicates

pd.concat([df1,df2]).drop_duplicates(keep=False)

Update :

Above method only working for those dataframes they do not have duplicate itself, For example

df1=pd.DataFrame({'A':[1,2,3,3],'B':[2,3,4,4]})
df2=pd.DataFrame({'A':[1],'B':[2]})

It will output like below , which is wrong

Wrong Output :

pd.concat([df1, df2]).drop_duplicates(keep=False)
Out[655]: 
   A  B
1  2  3

Correct Output

Out[656]: 
   A  B
1  2  3
2  3  4
3  3  4

How to achieve that?

Method 1: Using isin with tuple

df1[~df1.apply(tuple,1).isin(df2.apply(tuple,1))]
Out[657]: 
   A  B
1  2  3
2  3  4
3  3  4

Method 2: merge with indicator

df1.merge(df2,indicator = True, how='left').loc[lambda x : x['_merge']!='both']
Out[421]: 
   A  B     _merge
1  2  3  left_only
2  3  4  left_only
3  3  4  left_only

String secStore = System.getenv("SECONDARY_STORAGE");

File externalsdpath = new File(secStore);

This will get the path of external sd secondary storage.

Setting RetainSameConnection property to True for Excel manager Worked for me .

I solved this problem with:

    <div id="map" style="width: 100%; height: 100%; position: absolute;">
                 <div id="map-canvas"></div>
     </div>

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

You could use URL sequence substitution with a dummy query string (if you want to use CURL and save a few keystrokes):

curl http://www.myurl.com/?[1-20]

If you have other query strings in your URL, assign the sequence to a throwaway variable:

curl http://www.myurl.com/?myVar=111&fakeVar=[1-20]

Check out the URL section on the man page: https://curl.haxx.se/docs/manpage.html

If you want to selectively remove links without having to copy/edit entire xml files, a nice solution can be found in this post in the magento forums

In this solution, you override the Mage_Customer_Block_Account_Navigation block with a local version, that adds a removeLinkByName method, which you then use in your layout.xml files, like so:

<?xml version="1.0"?>
    <layout version="0.1.0">

    <customer_account>
        <reference name="customer_account_navigation" >
                <!-- remove the link using your custom method -->
                <action method="removeLinkByName">
                   <name>recurring_profiles</name>
                </action>
                <action method="removeLinkByName">
                   <name>billing_agreements</name>
                </action>
        </reference>
    </customer_account>
</layout>

I know this is an old question, but since I was just looking to do this, I thought I would post what I ended up with. Because I am using Bootstrap, I went with a Bootstrap option.

HTML

<div class="col-xs-12">
    <div class="form-group">
        <asp:HiddenField ID="hidType" runat="server" />
        <div class="btn-group" role="group" aria-label="Selection type" id="divType">
            <button type="button" class="btn btn-default BtnType" data-value="1">Food</button>                        
            <button type="button" class="btn btn-default BtnType" data-value="2">Drink</button>
        </div>
    </div>
</div>

jQuery

$(document).ready(function () {
    $('#divType button').click(function () {
        $(this).addClass('active').siblings().removeClass('active');
        $('#<%= hidType.ClientID%>').val($(this).data('value'));
        //alert($(this).data('value'));             
    });
});

I chose to store the value in a hidden field so that it would be easy for me to get the value server-side.

Instead of using the "c" tags, you could also do the following:

<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />

<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>

I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?

Sometimes you need to apply a function to the members of a list in place. The following code worked for me:

>>> def func(a, i):
...     a[i] = a[i].lower()
>>> a = ['TEST', 'TEXT']
>>> list(map(lambda i:func(a, i), range(0, len(a))))
[None, None]
>>> print(a)
['test', 'text']

Please note, the output of map() is passed to the list constructor to ensure the list is converted in Python 3. The returned list filled with None values should be ignored, since our purpose was to convert list a in place

The easiest way to do it is using Storyboard and a Segue.

Just create a Segue from the FirstViewController (not the Navigation Controller) of your TabBarController to a LoginViewController with the login UI and name it "showLogin".

Create a method that returns a BOOL to validate if the user logged in and/or his/her session is valid... preferably on the AppDelegate. Call it isSessionValid.

On your FirstViewController.m override the method viewDidAppear as follows:

- (void)viewDidAppear:(BOOL)animated
{
    [super viewDidAppear:animated];

    if([self isSessionValid]==NO){
        [self performSegueWithIdentifier:@"showLogin" sender:self];
    }
}

Then if the user logged in successfully, just dismiss or pop-out the LoginViewController to show your tabs.

Works 100%!

Hope it helps!

The Ookii VistaFolderBrowserDialog is the one you want.

If you only want the Folder Browser from Ooki Dialogs and nothing else then download the Source, cherry-pick the files you need for the Folder browser (hint: 7 files) and it builds fine in .NET 4.5.2. I had to add a reference to System.Drawing. Compare the references in the original project to yours.

How do you figure out which files? Open your app and Ookii in different Visual Studio instances. Add VistaFolderBrowserDialog.cs to your app and keep adding files until the build errors go away. You find the dependencies in the Ookii project - Control-Click the one you want to follow back to its source (pun intended).

Here are the files you need if you're too lazy to do that ...

NativeMethods.cs
SafeHandles.cs
VistaFolderBrowserDialog.cs
\ Interop
   COMGuids.cs
   ErrorHelper.cs
   ShellComInterfaces.cs
   ShellWrapperDefinitions.cs

Edit line 197 in VistaFolderBrowserDialog.cs unless you want to include their Resources.Resx

throw new InvalidOperationException(Properties.Resources.FolderBrowserDialogNoRootFolder);

throw new InvalidOperationException("Unable to retrieve the root folder.");

Add their copyright notice to your app as per their license.txt

The code in \Ookii.Dialogs.Wpf.Sample\MainWindow.xaml.cs line 160-169 is an example you can use but you will need to remove this, from MessageBox.Show(this, for WPF.

PDFBox is the best library I've found for this purpose, it's comprehensive and really quite easy to use if you're just doing basic text extraction. Examples can be found here.

It explains it on the page, but one thing to watch out for is that the start and end indexes when using setStartPage() and setEndPage() are both inclusive. I skipped over that explanation first time round and then it took me a while to realise why I was getting more than one page back with each call!

Itext is another alternative that also works with C#, though I've personally never used it. It's more low level than PDFBox, so less suited to the job if all you need is basic text extraction.

USE DataBaseName; GO --------- CREATE ROLE --------- CREATE ROLE Doctors ; GO  ---- Assign Role To users -------  CREATE USER [Username] FOR LOGIN [Domain\Username] EXEC sp_addrolemember N'Doctors', N'Username'  ----- GRANT Permission to Users Assinged with this Role----- GRANT ALL ON Table1, Table2, Table3 TO Doctors; GO 

My philosophy is this:

Create an activity only if it's absolutely absolutely required. With the back stack made available for committing bunch of fragment transactions, I try to create as few activities in my app as possible. Also, communicating between various fragments is much easier than sending data back and forth between activities.

Activity transitions are expensive, right? At least I believe so - since the old activity has to be destroyed/paused/stopped, pushed onto the stack, and then the new activity has to be created/started/resumed.

It's just my philosophy since fragments were introduced.

It's not possible with CSS3. There is a proposed CSS4 selector, $, to do just that, which could look like this (Selecting the li element):

ul $li ul.sub { ... }

See the list of CSS4 Selectors here.

As an alternative, with jQuery, a one-liner you could make use of would be this:

$('ul li:has(ul.sub)').addClass('has_sub');

You could then go ahead and style the li.has_sub in your CSS.

Your methods don't refer to an object (that is, self), so you should use the @staticmethod decorator:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

Check out the CharsetEncoder and CharsetDecoder API descriptions - You should follow a specific sequence of method calls to avoid this problem. For example, for CharsetEncoder:

1. Reset the encoder via the reset method, unless it has not been used before;
2. Invoke the encode method zero or more times, as long as additional input may be available, passing false for the endOfInput argument and filling the input buffer and flushing the output buffer between invocations;
3. Invoke the encode method one final time, passing true for the endOfInput argument; and then
4. Invoke the flush method so that the encoder can flush any internal state to the output buffer.

By the way, this is the same approach I am using for NIO although some of my colleagues are converting each char directly to a byte in the knowledge they are only using ASCII, which I can imagine is probably faster.

For python3 on Ubuntu

 sudo apt-get install python3-setuptools

If you are looking for a specific length (such as a zipcode field):

$("input").live("keyup", function( event ){
if(this.value.length == this.getAttribute('maxlength')) {
        //make ajax request here after.
    }
  });

Escape sequences (and variables too) work inside double quoted and heredoc strings. So change your code to:

echo '<p>' . $unit1 . "</p>\n";

PS: One clarification, single quotes strings do accept two escape sequences:

• \' when you want to use single quote inside single quoted strings
• \\ when you want to use backslash literally

If you need to concatenate paths with quotes, you can use = to replace quotes in a variable. This does not require you to know if the path already contains quotes or not. If there are no quotes, nothing is changed.

@echo off
rem Paths to combine
set DIRECTORY="C:\Directory with spaces"
set FILENAME="sub directory\filename.txt"

rem Combine two paths
set COMBINED="%DIRECTORY:"=%\%FILENAME:"=%"
echo %COMBINED%

rem This is just to illustrate how the = operator works
set DIR_WITHOUT_SPACES=%DIRECTORY:"=%
echo %DIR_WITHOUT_SPACES%

This SO post provides an answer as well as explanation why not to use exit(). Worth a read.

In short, you should return 0 in main(), as it will run all of the destructors and do object cleanup. Throwing would also work if you are exiting from an error.

Prior to Oracle 12C you cannot select from PL/SQL-defined tables, only from tables based on SQL types like this:

CREATE OR REPLACE TYPE exch_row AS OBJECT(
currency_cd VARCHAR2(9),
exch_rt_eur NUMBER,
exch_rt_usd NUMBER);


CREATE OR REPLACE TYPE exch_tbl AS TABLE OF exch_row;

In Oracle 12C it is now possible to select from PL/SQL tables that are defined in a package spec.

Typescript implementation based on top rated answer

/** Represents the `setTimeout` with an ability to perform pause/resume actions */
export class Timer {
    private _start: Date;
    private _remaining: number;
    private _durationTimeoutId?: NodeJS.Timeout;
    private _callback: (...args: any[]) => void;
    private _done = false;
    get done () {
        return this._done;
    }

    constructor(callback: (...args: any[]) => void, ms = 0) {
        this._callback = () => {
            callback();
            this._done = true;

        this._remaining = ms;
        this.resume();
    }

            this._clearTimeoutRef();
            this._remaining -= new Date().getTime() - this._start.getTime();
        }
        return this;
    }

    /** resumes the timer */
    resume(): Timer {

            this._start = new Date;
            this._durationTimeoutId = setTimeout(this._callback, this._remaining);

        return this;
    }

    /** 
     * clears the timeout and marks it as done.

    clearTimeout() {
        this._clearTimeoutRef();
        this._done = true;
    }

    private _clearTimeoutRef() {
        if (this._durationTimeoutId) {
            clearTimeout(this._durationTimeoutId);
            this._durationTimeoutId = undefined;

}

This will return all the values matching your key valueTitle

subList.SelectMany(m => m).Where(kvp => kvp.Key == "valueTitle").Select(k => k.Value).ToList();

If you use a Language Resource file to set the labels in your application you need to set the its value:

CultureInfo customCulture = new CultureInfo("en-US");
Languages.Culture = customCulture;

You may also consider the following solution:

let sum = options.set0.concat(options.set1);
const codeHTML = '<ol>' + sum.reduce((html, item) => {
    return html + "<li>" + item + "</li>";
        }, "") + '</ol>';
document.querySelector("#list").innerHTML = codeHTML;

Yes, this is impossible to modify the title of it. If you still want to have your own title, you can try to use other pop-up windows instead.

I want to recommend go-spew, which according to their github "Implements a deep pretty printer for Go data structures to aid in debugging"

go get -u github.com/davecgh/go-spew/spew

usage example:

import (
    "github.com/davecgh/go-spew/spew"
)

type Project struct {
    Id      int64  `json:"project_id"`
    Title   string `json:"title"`
    Name    string `json:"name"`
    Data    string `json:"data"`
    Commits string `json:"commits"`
}

func main() {

    o := Project{Name: "hello", Title: "world"}
    spew.Dump(o)
}

output:

(main.Project) {
 Id: (int64) 0,
 Title: (string) (len=5) "world",
 Name: (string) (len=5) "hello",
 Data: (string) "",
 Commits: (string) ""

Ok so a lot of people seem to be experiencing this issue. My problem was caused by references having paths to the bin folders of other projects, or referencing dlls from system folders. The project was about 6 years old and the previous developers had decided that this was the way they were going to reference their libraries.

The solution was to go through every reference and check the paths, then remove the reference and add it using NuGet. For any package that wasn't on NuGet I created another folder alongside packages and put the dll in there in the same layout as NuGet would.

I also had to go through the config files and make sure the correct version of the packages was being used. A long and painful process!

HAVING specifies a search condition for a group or an aggregate function used in SELECT statement.

If you really want them to have ALL rights:

use YourDatabase
go
exec sp_addrolemember 'db_owner', 'UserName'
go

Ditch FileWriter and FileReader, which are useless exactly because they do not allow you to specify the encoding. Instead, use

new OutputStreamWriter(new FileOutputStream(file), StandardCharsets.UTF_8)

and

new InputStreamReader(new FileInputStream(file), StandardCharsets.UTF_8);

Try forcing updates using the mvn cpu option:

usage: mvn [options] [<goal(s)>] [<phase(s)>]

Options:
 -cpu,--check-plugin-updates            Force upToDate check for any
                                        relevant registered plugins

jqPlot looks pretty good and it is open source.

Here's a link to the most impressive and up-to-date jqPlot examples.

One notable difference is that if you pass a .c file to gcc it will compile as C.

The default behavior of g++ is to treat .c files as C++ (unless -x c is specified).

Try with this :

jQuery('#main').css({ opacity: 0.6 });

This can be done quite easily using javascript XMLHttpRequest() class (AJAX):

function FileHelper()

{
    FileHelper.readStringFromFileAtPath = function(pathOfFileToReadFrom)
    {
        var request = new XMLHttpRequest();
        request.open("GET", pathOfFileToReadFrom, false);
        request.send(null);
        var returnValue = request.responseText;

        return returnValue;
    }
}

...

var text = FileHelper.readStringFromFileAtPath ( "mytext.txt" );

$("#images").load(location.href+" #images",function(){
    $.getScript("js/productHelper.js"); 
});

@JoinColumn(name="reference_column_name") annotation can be used above that property or field of class that is being referenced from some other entity.

if you are using Java 8, try this

Arrays.stream(e.getStackTrace())
                .map(s->s.toString())
                .collect(Collectors.joining("\n"));

you can find the code for getStackTrace() function provided by Throwable.java as :

public StackTraceElement[] getStackTrace() {
    return getOurStackTrace().clone();
}

and for StackTraceElement, it provides toString() as follows:

public String toString() {
    return getClassName() + "." + methodName +
        (isNativeMethod() ? "(Native Method)" :
         (fileName != null && lineNumber >= 0 ?
          "(" + fileName + ":" + lineNumber + ")" :
          (fileName != null ?  "("+fileName+")" : "(Unknown Source)")));
}

So just join the StackTraceElement with "\n".

Once you've dropped all the tables (and the indexes will disappear when the table goes) then there's nothing left in a SQLite database as far as I know, although the file doesn't seem to shrink (from a quick test I just did).

So deleting the file would seem to be fastest - it should just be recreated when your app tries to access the db file.

I had the same problem I used the solution offered above - I dropped the SYNONYM, created a VIEW with the same name as the synonym. it had a select using the dblink , and gave GRANT SELECT to the other schema It worked great.

You can do this pretty easily with Javascript+Jquery as below. If you want to exclude some column, just write an if statement inside the for loops to skip those columns. Hope this helps!

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.

Note this new function:

const char* myFunction()
{
    static char array[] = "my string";
    return array;
}

I defined "array" as static. Otherwise when the function ends, the variable (and the pointer you are returning) gets out of scope. Since that memory is allocated on the stack, and it will get corrupted. The downside of this implementation is that the code is not reentrant and not threadsafe.

Another alternative would be to use malloc to allocate the string in the heap, and then free on the correct locations of your code. This code will be reentrant and threadsafe.

As noted in the comment, this is a very bad practice, since an attacker can then inject code to your application (he/she needs to open the code using GDB, then make a breakpoint and modify the value of a returned variable to overflow and fun just gets started).

It is much more recommended to let the caller handle about memory allocations. See this new example:

char* myFunction(char* output_str, size_t max_len)
{
   const char *str = "my string";
   size_t l = strlen(str);
   if (l+1 > max_len) {
      return NULL;
   }
   strcpy(str, str, l);
   return input;
}

Note that the only content which can be modified is the one that the user. Another side effect - this code is now threadsafe, at least from the library point of view. The programmer calling this method should verify that the memory section used is threadsafe.

I'd create a cte and do an inner join. It's not efficient but it's convenient

with table as (
SELECT DATE, STATUS, TITLE, ROW_NUMBER() 
OVER (PARTITION BY DATE, STATUS,  TITLE ORDER BY QUANTITY ASC) AS Row_Num
 FROM TABLE)

select *

from table t
join select(
max(Row_Num) as Row_Num
,DATE
,STATUS
,TITLE
from table 
group by date, status, title) t2  
on t2.Row_Num = t.Row_Num and t2
and t2.date = t.date
and t2.title = t.title

It won't let you map back onto Product since that is your table you are querying. You need an anonymous function, then you can add it to a ViewModel, and add each ViewModel to a List<MyViewModel> and return these. It's a slight digression, but I include caveats about handling nullable dates because these are a pain in the behind to deal with, just in case you have any. This is how I handled it.

Hopefully you have a ProductViewModel:

public class ProductViewModel
{
    [Key]
    public string ID { get; set; }
    public string Name { get; set; }
}

I have dependency injection/repository framework where I call a function to grab my data. Using your post as an example, in your Controller function call, it would look like this:

int categoryID = 1;
var prods = repository.GetProducts(categoryID);

In the repository class:

public IEnumerable<ProductViewModel> GetProducts(int categoryID)
{
   List<ProductViewModel> lstPVM = new List<ProductViewModel>();

   var anonymousObjResult = from p in db.Products
                            where p.CategoryID == categoryID 
                            select new
                            {
                                CatID = p.CategoryID,
                                Name = p.Name
                            };

        // NOTE: If you have any dates that are nullable and null, you'll need to
        // take care of that:  ClosedDate = (DateTime?)p.ClosedDate ?? DateTime.Now

        // If you want a particular date, you have to define a DateTime variable,
        // assign your value to it, then replace DateTime.Now with that variable. You
        // cannot call a DateTime.Parse there, unfortunately. 
        // Using 
        //    new Date("1","1","1800"); 
        // works, though. (I add a particular date so I can edit it out later.)

        // I do this foreach below so I can return a List<ProductViewModel>. 
        // You could do: return anonymousObjResult.ToList(); here
        // but it's not as clean and is an anonymous type instead of defined
        // by a ViewModel where you can control the individual field types

        foreach (var a in anonymousObjResult)
        {                
            ProductViewModel pvm = new ProductViewModel();
            pvm.ID = a.CatID;  
            pvm.Name = a.Name;
            lstPVM.Add(rvm);
        }

        // Obviously you will just have ONE item there, but I built it 
        // like this so you could bring back the whole table, if you wanted
        // to remove your Where clause, above.

        return lstPVM;
    }

Back in the controller, you do:

 List<ProductViewModel> lstProd = new List<ProductViewModel>();

 if (prods != null) 
 {
    // For setting the dates back to nulls, I'm looking for this value:
    // DateTime stdDate = DateTime.Parse("01/01/1800");

    foreach (var a in prods)
    {
        ProductViewModel o_prod = new ReportViewModel();
        o_prod.ID = a.ID;
        o_prod.Name = a.Name;
       // o_prod.ClosedDate = a.ClosedDate == stdDate ? null : a.ClosedDate;
        lstProd.Add(o_prod);
    }
}
return View(lstProd);  // use this in your View as:   @model IEnumerable<ProductViewModel>

The way I solved this was using flexbox. By using flexbox to layout the contents of your container div, you can have flexbox automatically distribute free space to an item above the one you want to have "stick to the bottom".

For example, say this is your container div with some other block elements inside it, and that the blue box (third one down) is a paragraph and the purple box (last one) is the one you want to have "stick to the bottom".

By setting this layout up with flexbox, you can set flex-grow: 1; on just the paragraph (blue box) and, if it is the only thing with flex-grow: 1;, it will be allocated ALL of the remaining space, pushing the element(s) after it to the bottom of the container like this:

(apologies for the terrible, quick-and-dirty graphics)

A unit test is a test written by the programmer to verify that a relatively small piece of code is doing what it is intended to do. They are narrow in scope, they should be easy to write and execute, and their effectiveness depends on what the programmer considers to be useful. The tests are intended for the use of the programmer, they are not directly useful to anybody else, though, if they do their job, testers and users downstream should benefit from seeing fewer bugs.

Part of being a unit test is the implication that things outside the code under test are mocked or stubbed out. Unit tests shouldn't have dependencies on outside systems. They test internal consistency as opposed to proving that they play nicely with some outside system.

An integration test is done to demonstrate that different pieces of the system work together. Integration tests can cover whole applications, and they require much more effort to put together. They usually require resources like database instances and hardware to be allocated for them. The integration tests do a more convincing job of demonstrating the system works (especially to non-programmers) than a set of unit tests can, at least to the extent the integration test environment resembles production.

Actually "integration test" gets used for a wide variety of things, from full-on system tests against an environment made to resemble production to any test that uses a resource (like a database or queue) that isn't mocked out. At the lower end of the spectrum an integration test could be a junit test where a repository is exercised against an in-memory database, toward the upper end it could be a system test verifying applications can exchange messages.

To read bytes use std::bitset

const int bits_in_byte = 8;

char myChar = 's';
cout << bitset<sizeof(myChar) * bits_in_byte>(myChar);

To write you need to use bit-wise operators such as & ^ | & << >>. make sure to learn what they do.

For example to have 00100100 you need to set the first bit to 1, and shift it with the << >> operators 5 times. if you want to continue writing you just continue to set the first bit and shift it. it's very much like an old typewriter: you write, and shift the paper.

For 00100100: set the first bit to 1, shift 5 times, set the first bit to 1, and shift 2 times:

const int bits_in_byte = 8;

char myChar = 0;
myChar = myChar | (0x1 << 5 | 0x1 << 2);
cout << bitset<sizeof(myChar) * bits_in_byte>(myChar);

For i = 0 To dt.Rows.Count - 1

    ListV.Items.Add(dt.Rows(i).Item("STU_NUMBER").ToString)
    ListV.Items(i).SubItems.Add(dt.Rows(i).Item("FNAME").ToString & " " & dt.Rows(i).Item("MI").ToString & ". " & dt.Rows(i).Item("LNAME").ToString)
    ListV.Items(i).SubItems.Add(dt.Rows(i).Item("SEX").ToString)

Next

There is a circumstance where you're required to declare it final --otherwise it will result in compile error--, namely passing them through into anonymous classes. Basic example:

public FileFilter createFileExtensionFilter(final String extension) {
    FileFilter fileFilter = new FileFilter() {
        public boolean accept(File pathname) {
            return pathname.getName().endsWith(extension);
        }
    };

    // What would happen when it's allowed to change extension here?
    // extension = "foo";

    return fileFilter;
}

Removing the final modifier would result in compile error, because it isn't guaranteed anymore that the value is a runtime constant. Changing the value from outside the anonymous class would namely cause the anonymous class instance to behave different after the moment of creation.

This should work:

soup = BeautifulSoup(sdata)
mydivs = soup.findAll('div')
for div in mydivs: 
    if (div.find(class_ == "stylelistrow"):
        print div

Mostly the image is not displayed because you URL contains spaces. In your case you almost did everything correct. Except one thing - you have not added single quotes like you do if you specify background-image in css I.e.

.bg-img {                \/          \/
    background-image: url('http://...');
}

To do so escape quot character in HTML via \'

                                          \/                                  \/
<div [ngStyle]="{'background-image': 'url(\''+ item.color.catalogImageLink + '\')'}"></div>

           C      D key

You can use itoa function to convert the integer to a string.

You can use strcat function to append characters in a string at the end of another string.

If you want to convert a integer to a character, just do the following -

int a = 65;
char c = (char) a;

Note that since characters are smaller in size than integer, this casting may cause a loss of data. It's better to declare the character variable as unsigned in this case (though you may still lose data).

To do a light reading about type conversion, go here.

If you are still having trouble, comment on this answer.

Edit

Go here for a more suitable example of joining characters.

Also some more useful link is given below -

1. http://www.cplusplus.com/reference/clibrary/cstring/strncat/
2. http://www.cplusplus.com/reference/clibrary/cstring/strcat/

Second Edit

char msg[200];
int msgLength;
char rankString[200];

........... // Your message has arrived
msgLength = strlen(msg);
itoa(rank, rankString, 10); // I have assumed rank is the integer variable containing the rank id

strncat( msg, rankString, (200 - msgLength) );  // msg now contains previous msg + id

// You may loose some portion of id if message length + id string length is greater than 200

Third Edit

Go to this link. Here you will find an implementation of itoa. Use that instead.

Depending on how much you know about the input, you may have to take into account that not all Unicode characters are valid XML characters.

Both Server.HtmlEncode and System.Security.SecurityElement.Escape seem to ignore illegal XML characters, while System.XML.XmlWriter.WriteString throws an ArgumentException when it encounters illegal characters (unless you disable that check in which case it ignores them). An overview of library functions is available here.

Depends on what you have. If your svg icon is just a path, then it's easy enough to add that glyph by just copying the 'd' attribute to a new <glyph> element. However, the path needs to be scaled to the font's coordinate system (the EM-square, which typically is [0,0,2048,2048] - the standard for Truetype fonts) and aligned with the baseline you want.

Not all browsers support svg fonts however, so you're going to have to convert it to other formats too if you want it to work everywhere.

Fontforge can import svg files (select a glyph slot, File > Import and then select your svg image), and you can then convert to all the relevant font formats (svg, truetype, woff etc).

Using std::wstring and wchar_t (requires the Unicode header):

//#include <tchar.h>
std::wstring phone(L"(555) 555-5555");

...fancy static range initializer next; not necessary to setup badChars2 this exact same way. It's overkill; more academic than anything else:

const wchar_t *tmp = L"()-"; 
const std::set<wchar_t> badChars2(tmp,tmp + sizeof(tmp)-1);

Simple, concise lambda:

1. Uses phone in the lambda capture list.
2. Uses Erase-remove idiom

3. Removes all bad characters from phone

   for_each(badChars2.begin(), badChars2.end(), [&phone](wchar_t n){
        phone.erase(std::remove(phone.begin(), phone.end(), n), phone.end());
   });
   wcout << phone << endl;
   

Output: "555 5555555"

This is my way to setup Servlet as welcome page.

I share for whom concern.

web.xml

  <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>
    <servlet>
        <servlet-name>Demo</servlet-name>
        <servlet-class>servlet.Demo</servlet-class>
    </servlet>
    <servlet-mapping>
        <servlet-name>Demo</servlet-name>
        <url-pattern></url-pattern>
    </servlet-mapping>

Servlet class

@WebServlet(name = "/demo")
public class Demo extends HttpServlet {
   public void doGet(HttpServletRequest req, HttpServletResponse res)
     throws ServletException, IOException  {
       RequestDispatcher rd = req.getRequestDispatcher("index.jsp");
   }
}

To make that fragment come again, just add that fragment to backstack which you want to come on back pressed, Eg:

button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Fragment fragment = new LoginFragment();
        //replacing the fragment
        if (fragment != null) {
            FragmentTransaction ft = ((FragmentActivity)getContext()).getSupportFragmentManager().beginTransaction();
            ft.replace(R.id.content_frame, fragment);
            ft.addToBackStack("SignupFragment");
            ft.commit();
        }
    }
});

In the above case, I am opening LoginFragment when Button button is pressed, right now the user is in SignupFragment. So if addToBackStack(TAG) is called, where TAG = "SignupFragment", then when back button is pressed in LoginFragment, we come back to SignUpFragment.

Happy Coding!

Pls find below where I have explained with data in the array after case 1 & case 2.

char sc_ArrData[ 100 ];
strcpy(sc_ArrData,"Hai" );

Case 1:

sc_ArrData[0] = '\0';

Result:

-   "sc_ArrData"
[0] 0 ''
[1] 97 'a'
[2] 105 'i'
[3] 0 ''

Case 2:

memset(&sc_ArrData[0], 0, sizeof(sc_ArrData));

Result:

-   "sc_ArrData"
[0] 0 ''
[1] 0 ''
[2] 0 ''
[3] 0 ''

Though setting first argument to NULL will do the trick, using memset is advisable

All cookies are client and server

There is no difference. A regular cookie can be set server side or client side. The 'classic' cookie will be sent back with each request. A cookie that is set by the server, will be sent to the client in a response. The server only sends the cookie when it is explicitly set or changed, while the client sends the cookie on each request.

But essentially it's the same cookie.

But, behavior can change

A cookie is basically a name=value pair, but after the value can be a bunch of semi-colon separated attributes that affect the behavior of the cookie if it is so implemented by the client (or server). Those attributes can be about lifetime, context and various security settings.

HTTP-only (is not server-only)

One of those attributes can be set by a server to indicate that it's an HTTP-only cookie. This means that the cookie is still sent back and forth, but it won't be available in JavaScript. Do note, though, that the cookie is still there! It's only a built in protection in the browser, but if somebody would use a ridiculously old browser like IE5, or some custom client, they can actually read the cookie!

So it seems like there are 'server cookies', but there are actually not. Those cookies are still sent to the client. On the client there is no way to prevent a cookie from being sent to the server.

Alternatives to achieve 'only-ness'

If you want to store a value only on the server, or only on the client, then you'd need some other kind of storage, like a file or database on the server, or Local Storage on the client.

This should do the trick

export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get -q -y install mysql-server

Of course, it leaves you with a blank root password - so you'll want to run something like

mysqladmin -u root password mysecretpasswordgoeshere

Afterwards to add a password to the account.

You can make function getStyles that'll take an element and other arguments are properties that's values you want.

const convertRestArgsIntoStylesArr = ([...args]) => {
    return args.slice(1);
}

const getStyles = function () {
    const args = [...arguments];
    const [element] = args;

    let stylesProps = [...args][1] instanceof Array ? args[1] : convertRestArgsIntoStylesArr(args);

    const styles = window.getComputedStyle(element);
    const stylesObj = stylesProps.reduce((acc, v) => {
        acc[v] = styles.getPropertyValue(v);
        return acc;
    }, {});

    return stylesObj;
};

Now, you can use this function like this:

const styles = getStyles(document.body, "height", "width");

OR

const styles = getStyles(document.body, ["height", "width"]);

If you're using jQuery Cookie (https://plugins.jquery.com/cookie/), you can use decimal point or fractions.

As one day is 1, one minute would be 1 / 1440 (there's 1440 minutes in a day).

So 30 minutes is 30 / 1440 = 0.02083333.

Final code:

$.cookie("example", "foo", { expires: 30 / 1440, path: '/' });

I've added path: '/' so that you don't forget that the cookie is set on the current path. If you're on /my-directory/ the cookie is only set for this very directory.

Just adding a little more info.

JPA manages the version under the hood for you, however it doesn't do so when you update your record via JPAUpdateClause, in such cases you need to manually add the version increment to the query.

Same can be said about updating via JPQL, i.e. not a simple change to the entity, but an update command to the database even if that is done by hibernate

I had content that was longer than the dialog. On open, the dialog would scoll to the first :tabbable which was at the bottom. Here was my fix.

   open: function(event, ui) { $(this).scrollTop(0); }
});

Just try this in Javascript:

 $previous = "javascript:history.go(-1)";

Or you can try it in PHP:

if(isset($_SERVER['HTTP_REFERER'])) {
    $previous = $_SERVER['HTTP_REFERER'];
}

Use @RequestParam in your method arguments so Spring can bind them, also use the @RequestMapping.params array to narrow the method that will be used by spring. Sample code:

@RequestMapping("/userGrid", 
params = {"_search", "nd", "rows", "page", "sidx", "sort"})
public @ResponseBody GridModel getUsersForGrid(
@RequestParam(value = "_search") String search, 
@RequestParam(value = "nd") int nd, 
@RequestParam(value = "rows") int rows, 
@RequestParam(value = "page") int page, 
@RequestParam(value = "sidx") int sidx, 
@RequestParam(value = "sort") Sort sort) {
// Stuff here
}

This way Spring will only execute this method if ALL PARAMETERS are present saving you from null checking and related stuff.

If you don't want _id in response, you can refactor your code something like this:

jsonResponse = getResponse(mock_data)
del jsonResponse['_id'] # removes '_id' from the final response
return jsonResponse

This will remove the TypeError: ObjectId('') is not JSON serializable error.

I've a way and work like this:

<'a href="FOLDER_PATH" target="_explorer.exe">Link Text<'/a>

Note: The following applies to Windows PowerShell.
See the next section for the cross-platform PowerShell Core (v6+) edition.

• On PSv5.1 or higher, where > and >> are effectively aliases of Out-File, you can set the default encoding for > / >> / Out-File via the $PSDefaultParameterValues preference variable:

  • $PSDefaultParameterValues['Out-File:Encoding'] = 'utf8'

• On PSv5.0 or below, you cannot change the encoding for > / >>, but, on PSv3 or higher, the above technique does work for explicit calls to Out-File.
  (The $PSDefaultParameterValues preference variable was introduced in PSv3.0).

• On PSv3.0 or higher, if you want to set the default encoding for all cmdlets that support
  an -Encoding parameter (which in PSv5.1+ includes > and >>), use:

  • $PSDefaultParameterValues['*:Encoding'] = 'utf8'

If you place this command in your $PROFILE, cmdlets such as Out-File and Set-Content will use UTF-8 encoding by default, but note that this makes it a session-global setting that will affect all commands / scripts that do not explicitly specify an encoding via their -Encoding parameter.

Similarly, be sure to include such commands in your scripts or modules that you want to behave the same way, so that they indeed behave the same even when run by another user or a different machine; however, to avoid a session-global change, use the following form to create a local copy of $PSDefaultParameterValues:

• $PSDefaultParameterValues = @{ '*:Encoding' = 'utf8' }

Caveat: PowerShell, as of v5.1, invariably creates UTF-8 files _with a (pseudo) BOM_, which is customary only in the Windows world - Unix-based utilities do not recognize this BOM (see bottom); see this post for workarounds that create BOM-less UTF-8 files.

For a summary of the wildly inconsistent default character encoding behavior across many of the Windows PowerShell standard cmdlets, see the bottom section.

The automatic $OutputEncoding variable is unrelated, and only applies to how PowerShell communicates with external programs (what encoding PowerShell uses when sending strings to them) - it has nothing to do with the encoding that the output redirection operators and PowerShell cmdlets use to save to files.

Optional reading: The cross-platform perspective: PowerShell Core:

PowerShell is now cross-platform, via its PowerShell Core edition, whose encoding - sensibly - defaults to BOM-less UTF-8, in line with Unix-like platforms.

• This means that source-code files without a BOM are assumed to be UTF-8, and using > / Out-File / Set-Content defaults to BOM-less UTF-8; explicit use of the utf8 -Encoding argument too creates BOM-less UTF-8, but you can opt to create files with the pseudo-BOM with the utf8bom value.

• If you create PowerShell scripts with an editor on a Unix-like platform and nowadays even on Windows with cross-platform editors such as Visual Studio Code and Sublime Text, the resulting *.ps1 file will typically not have a UTF-8 pseudo-BOM:

  • This works fine on PowerShell Core.
  • It may break on Windows PowerShell, if the file contains non-ASCII characters; if you do need to use non-ASCII characters in your scripts, save them as UTF-8 with BOM.
    Without the BOM, Windows PowerShell (mis)interprets your script as being encoded in the legacy "ANSI" codepage (determined by the system locale for pre-Unicode applications; e.g., Windows-1252 on US-English systems).

• Conversely, files that do have the UTF-8 pseudo-BOM can be problematic on Unix-like platforms, as they cause Unix utilities such as cat, sed, and awk - and even some editors such as gedit - to pass the pseudo-BOM through, i.e., to treat it as data.

  • This may not always be a problem, but definitely can be, such as when you try to read a file into a string in bash with, say, text=$(cat file) or text=$(<file) - the resulting variable will contain the pseudo-BOM as the first 3 bytes.

Inconsistent default encoding behavior in Windows PowerShell:

Regrettably, the default character encoding used in Windows PowerShell is wildly inconsistent; the cross-platform PowerShell Core edition, as discussed in the previous section, has commendably put and end to this.

Note:

• The following doesn't aspire to cover all standard cmdlets.

• Googling cmdlet names to find their help topics now shows you the PowerShell Core version of the topics by default; use the version drop-down list above the list of topics on the left to switch to a Windows PowerShell version.

• As of this writing, the documentation frequently incorrectly claims that ASCII is the default encoding in Windows PowerShell - see this GitHub docs issue.

Cmdlets that write:

Out-File and > / >> create "Unicode" - UTF-16LE - files by default - in which every ASCII-range character (too) is represented by 2 bytes - which notably differs from Set-Content / Add-Content (see next point); New-ModuleManifest and Export-CliXml also create UTF-16LE files.

Set-Content (and Add-Content if the file doesn't yet exist / is empty) uses ANSI encoding (the encoding specified by the active system locale's ANSI legacy code page, which PowerShell calls Default).

Export-Csv indeed creates ASCII files, as documented, but see the notes re -Append below.

Export-PSSession creates UTF-8 files with BOM by default.

New-Item -Type File -Value currently creates BOM-less(!) UTF-8.

The Send-MailMessage help topic also claims that ASCII encoding is the default - I have not personally verified that claim.

Start-Transcript invariably creates UTF-8 files with BOM, but see the notes re -Append below.

Re commands that append to an existing file:

>> / Out-File -Append make no attempt to match the encoding of a file's existing content. That is, they blindly apply their default encoding, unless instructed otherwise with -Encoding, which is not an option with >> (except indirectly in PSv5.1+, via $PSDefaultParameterValues, as shown above). In short: you must know the encoding of an existing file's content and append using that same encoding.

Add-Content is the laudable exception: in the absence of an explicit -Encoding argument, it detects the existing encoding and automatically applies it to the new content.^{Thanks, js2010}. Note that in Windows PowerShell this means that it is ANSI encoding that is applied if the existing content has no BOM, whereas it is UTF-8 in PowerShell Core.

This inconsistency between Out-File -Append / >> and Add-Content, which also affects PowerShell Core, is discussed in this GitHub issue.

Export-Csv -Append partially matches the existing encoding: it blindly appends UTF-8 if the existing file's encoding is any of ASCII/UTF-8/ANSI, but correctly matches UTF-16LE and UTF-16BE.
To put it differently: in the absence of a BOM, Export-Csv -Append assumes UTF-8 is, whereas Add-Content assumes ANSI.

Start-Transcript -Append partially matches the existing encoding: It correctly matches encodings with BOM, but defaults to potentially lossy ASCII encoding in the absence of one.

Cmdlets that read (that is, the encoding used in the absence of a BOM):

Get-Content and Import-PowerShellDataFile default to ANSI (Default), which is consistent with Set-Content.
ANSI is also what the PowerShell engine itself defaults to when it reads source code from files.

By contrast, Import-Csv, Import-CliXml and Select-String assume UTF-8 in the absence of a BOM.

You have to perform your search in the domain:

Wrap your Promise inside a function or it will start to do its job right away. Plus, you can pass parameters to the function:

var some_function = function(username, password)
{
 return new Promise(function(resolve, reject)
 {
  /*stuff using username, password*/
  if ( /* everything turned out fine */ )
  {
   resolve("Stuff worked!");
  }
  else
  {
   reject(Error("It broke"));
  }
 });
}

Then, use it:

some_module.some_function(username, password).then(function(uid)
{
 // stuff
})

ES6:

const some_function = (username, password) =>
{
 return new Promise((resolve, reject) =>
 {
  /*stuff using username, password*/

  if ( /* everything turned out fine */ )
  {
   resolve("Stuff worked!");
  }
  else
  {
   reject(Error("It broke"));
  }
 });
};

Use:

some_module.some_function(username, password).then(uid =>
{
 // stuff
});

PHP does not have permissions to write on /tmp directory. You need to use chmod command to open /tmp permissions.

I don't think you could change the style of browsers' default alert boxes.

You need to create your own or use a simple and customizable library like xdialog. Following is a example to customize the alert box. More demos can be found here.

Using Remove or RemoveAt on a list while iterating over that list has intentionally been made difficult, because it is almost always the wrong thing to do. You might be able to get it working with some clever trick, but it would be extremely slow. Every time you call Remove it has to scan through the entire list to find the element you want to remove. Every time you call RemoveAt it has to move subsequent elements 1 position to the left. As such, any solution using Remove or RemoveAt, would require quadratic time, O(n²).

Use RemoveAll if you can. Otherwise, the following pattern will filter the list in-place in linear time, O(n).

// Create a list to be filtered
IList<int> elements = new List<int>(new int[] {1, 2, 3, 4, 5, 6, 7, 8, 9, 10});
// Filter the list
int kept = 0;
for (int i = 0; i < elements.Count; i++) {
    // Test whether this is an element that we want to keep.
    if (elements[i] % 3 > 0) {
        // Add it to the list of kept elements.
        elements[kept] = elements[i];
        kept++;
    }
}
// Unfortunately IList has no Resize method. So instead we
// remove the last element of the list until: elements.Count == kept.
while (kept < elements.Count) elements.RemoveAt(elements.Count-1);

There are several options to make curl output to a file

 # saves it to myfile.txt
curl http://www.example.com/data.txt -o myfile.txt

# The #1 will get substituted with the url, so the filename contains the url
curl http://www.example.com/data.txt -o "file_#1.txt" 

# saves to data.txt, the filename extracted from the URL
curl http://www.example.com/data.txt -O 

# saves to filename determined by the Content-Disposition header sent by the server.
curl http://www.example.com/data.txt -O -J 

For assigning an element's class in a child component you can simply use an @Input string in the child's component and use it as an expression inside the template. Here is an example of something we did to change the icon and button type in a shared Bootstrap loading button component, without affecting how it was already used throughout the codebase:

app-loading-button.component.html (child)

<button class="btn {{additionalClasses}}">...</button>

app-loading-button.component.ts

@Input() additionalClasses: string;

parent.html

<app-loading-button additionalClasses="fa fa-download btn-secondary">...</app-loading-button>
