You can avoid std::bind doing this:

std::function<void(void)> f = [this]-> {Foo::doSomething();}

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

The following should work

$ad->getcodes()->distinct()->count('pid');

If you repository supports tokens (for example GitLab) then generate a token for your user then navigate to the file you will download and click on RAW output to get the URL. To download the file use:

curl --silent --request GET --header 'PRIVATE-TOKEN: replace_with_your_token' \
'http://git.example.com/foo/bar.sql' --output /tmp/bar.sql

Use HttpClientBuilder to build the HttpClient instead of using DefaultHttpClient

ex:

MinimalHttpClient httpclient = new HttpClientBuilder().build();

 // Prepare a request object
 HttpGet httpget = new HttpGet("http://www.apache.org/");

Another option to check your xpath is to use selenium IDE.

1. Install Firefox Selenium IDE
2. Open your application in FireFox and open IDE
3. In IDE, on a new line, paste your xpath to the target and click Find. The corresponding element would be highlighted in your application

The issue has been correctly identified as related to variance but the details are not correct. A purely functional list is a covariant data functor, which means if a type Sub is a subtype of Super, then a list of Sub is definitely a subtype of a list of Super.

However mutability of a list is not the basic problem here. The problem is mutability in general. The problem is well known, and is called the Covariance Problem, it was first identified I think by Castagna, and it completely and utterly destroys object orientation as a general paradigm. It is based on previously established variance rules established by Cardelli and Reynolds.

Somewhat oversimplifying, lets consider assignment of an object B of type T to an object A of type T as a mutation. This is without loss of generality: a mutation of A can be written A = f (A) where f: T -> T. The problem, of course, is that whilst functions are covariant in their codomain, they're contravariant in their domain, but with assignments the domain and codomain are the same, so assignment is invariant!

It follows, generalising, that subtypes cannot be mutated. But with object orientation mutation is fundamental, hence object orientation is intrinsically flawed.

Here's a simple example: in a purely functional setting a symmetric matrix is clearly a matrix, it is a subtype, no problem. Now lets add to matrix the ability to set a single element at coordinates (x,y) with the rule no other element changes. Now symmetric matrix is no longer a subtype, if you change (x,y) you have also changed (y,x). The functional operation is delta: Sym -> Mat, if you change one element of a symmetric matrix you get a general non-symmetric matrix back. Therefore if you included a "change one element" method in Mat, Sym is not a subtype. In fact .. there are almost certainly NO proper subtypes.

To put all this in easier terms: if you have a general data type with a wide range of mutators which leverage its generality you can be certain any proper subtype cannot possibly support all those mutations: if it could, it would be just as general as the supertype, contrary to the specification of "proper" subtype.

The fact Java prevents subtyping mutable lists fails to address the real issue: why are you using object oriented rubbish like Java when it was discredited several decades ago??

In any case there's a reasonable discussion here:

https://en.wikipedia.org/wiki/Covariance_and_contravariance_(computer_science)

If you are passing data to a DOM element from the server, you should set the data on the element:

<a id="foo" data-foo="bar" href="#">foo!</a>

The data can then be accessed using .data() in jQuery:

console.log( $('#foo').data('foo') );
//outputs "bar"

However when you store data on a DOM node in jQuery using data, the variables are stored on the node object. This is to accommodate complex objects and references as storing the data on the node element as an attribute will only accommodate string values.

$('#foo').data('foo', 'baz');

console.log( $('#foo').attr('data-foo') );
//outputs "bar" as the attribute was never changed

console.log( $('#foo').data('foo') );
//outputs "baz" as the value has been updated on the object

Also, the naming convention for data attributes has a bit of a hidden "gotcha":

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('fooBarBaz') );
//outputs "fizz-buzz" as hyphens are automatically camelCase'd

The hyphenated key will still work:

<a id="bar" data-foo-bar-baz="fizz-buzz" href="#">fizz buzz!</a>

console.log( $('#bar').data('foo-bar-baz') );
//still outputs "fizz-buzz"

However the object returned by .data() will not have the hyphenated key set:

$('#bar').data().fooBarBaz; //works
$('#bar').data()['fooBarBaz']; //works
$('#bar').data()['foo-bar-baz']; //does not work

It's for this reason I suggest avoiding the hyphenated key in javascript.

For HTML, keep using the hyphenated form. HTML attributes are supposed to get ASCII-lowercased automatically, so <div data-foobar></div>, <DIV DATA-FOOBAR></DIV>, and <dIv DaTa-FoObAr></DiV> are supposed to be treated as identical, but for the best compatibility the lower case form should be preferred.

The .data() method will also perform some basic auto-casting if the value matches a recognized pattern:

<a id="foo"
    href="#"
    data-str="bar"
    data-bool="true"
    data-num="15"
    data-json='{"fizz":["buzz"]}'>foo!</a>

$('#foo').data('str');  //`"bar"`
$('#foo').data('bool'); //`true`
$('#foo').data('num');  //`15`
$('#foo').data('json'); //`{fizz:['buzz']}`

This auto-casting ability is very convenient for instantiating widgets & plugins:

$('.widget').each(function () {
    $(this).widget($(this).data());
    //-or-
    $(this).widget($(this).data('widget'));
});

If you absolutely must have the original value as a string, then you'll need to use .attr():

<a id="foo" href="#" data-color="ABC123"></a>
<a id="bar" href="#" data-color="654321"></a>

$('#foo').data('color').length; //6
$('#bar').data('color').length; //undefined, length isn't a property of numbers

$('#foo').attr('data-color').length; //6
$('#bar').attr('data-color').length; //6

_{This was a contrived example. For storing color values, I used to use numeric hex notation (i.e. 0xABC123), but it's worth noting that hex was parsed incorrectly in jQuery versions before 1.7.2, and is no longer parsed into a Number as of jQuery 1.8 rc 1.}

jQuery 1.8 rc 1 changed the behavior of auto-casting. Before, any format that was a valid representation of a Number would be cast to Number. Now, values that are numeric are only auto-cast if their representation stays the same. This is best illustrated with an example.

<a id="foo"
    href="#"
    data-int="1000"
    data-decimal="1000.00"
    data-scientific="1e3"
    data-hex="0x03e8">foo!</a>

                              // pre 1.8    post 1.8
$('#foo').data('int');        //    1000        1000
$('#foo').data('decimal');    //    1000   "1000.00"
$('#foo').data('scientific'); //    1000       "1e3"
$('#foo').data('hex');        //    1000     "0x03e8"

If you plan on using alternative numeric syntaxes to access numeric values, be sure to cast the value to a Number first, such as with a unary + operator.

+$('#foo').data('hex'); // 1000

Like the other answers say, you can't remove an item from a collection you're iterating over. You can get around this by explicitly using an Iterator and removing the item there.

Iterator<Item> iter = list.iterator();
while(iter.hasNext()) {
  Item blah = iter.next();
  if(...) {
    iter.remove(); // Removes the 'current' item
  }
}

you can use TextBlock control and assign the text property.

I guess the thread that needs to be killed is either in any kind of waiting mode, or doing some heavy job. I would suggest using a "naive" way.

Define some global boolean:

std::atomic_bool stop_thread_1 = false;

Put the following code (or similar) in several key points, in a way that it will cause all functions in the call stack to return until the thread naturally ends:

if (stop_thread_1)
    return;

Then to stop the thread from another (main) thread:

stop_thread_1 = true;
thread1.join ();
stop_thread_1 = false; //(for next time. this can be when starting the thread instead)

You can use deparse and substitute to get the name of a function argument:

myfunc <- function(v1) {
  deparse(substitute(v1))
}

myfunc(foo)
[1] "foo"

There are at least five different ways to break out of two or more loops:

1) Set parent(s) loop to the end

for (i = 0; i < 5; i++)
{
    for (j = 0; j < 5; j++)
    {
        if (j === 2)
        {
            i = 5;
            break;
        }
    }
}

2) Use label

fast:
for (i = 0; i < 5; i++)
{
    for (j = 0; j < 5; j++)
    {
        if (j === 2)
            break fast;
    }
}

3) Use variable

var exit_loops = false;
for (i = 0; i < 5; i++)
{
    for (j = 0; j < 5; j++)
    {
        if (j === 2)
        {
            exit_loops = true;
            break;
        }
    }
    if (exit_loops)
        break;
}

4) Use self executing function

(function()
{
    for (i = 0; i < 5; i++)
    {
        for (j = 0; j < 5; j++)
        {
             if (j === 2)
                 return;
        }
    }
})();

5) Use regular function

function nested_loops()
{
    for (i = 0; i < 5; i++)
    {
        for (j = 0; j < 5; j++)
        {
             if (j === 2)
                 return;
        }
    }
}
nested_loops();

Any recommendation on how to fix this?

Several. You can use bind:

for (i = 0; i < j; i++) {
    asycronouseProcess(function (i) {
        alert(i);
    }.bind(null, i));
}

Or, if your browser supports let (it will be in the next ECMAScript version, however Firefox already supports it since a while) you could have:

for (i = 0; i < j; i++) {
    let k = i;
    asycronouseProcess(function() {
        alert(k);
    });
}

Or, you could do the job of bind manually (in case the browser doesn't support it, but I would say you can implement a shim in that case, it should be in the link above):

for (i = 0; i < j; i++) {
    asycronouseProcess(function(i) {
        return function () {
            alert(i)
        }
    }(i));
}

I usually prefer let when I can use it (e.g. for Firefox add-on); otherwise bind or a custom currying function (that doesn't need a context object).

ls | shuf -n 10 # ten random files

If you wish to stream the CSV out to the user without creating a file then I found the following to be the simplest method. You can use any extension/method to create the ToCsv() function (which returns a string based on the given DataTable).

        var report = myDataTable.ToCsv();
        var bytes = Encoding.GetEncoding("iso-8859-1").GetBytes(report);

        Response.Buffer = true;
        Response.Clear();
        Response.AddHeader("content-disposition", "attachment; filename=report.csv");
        Response.ContentType = "text/csv";
        Response.BinaryWrite(bytes);
        Response.End();

If you don't care about IE6 users, use the equality attribute selector.

label[for="foo"] { display:none; }

For React Native, React, and For Node project, below one is working

yarn add  query-string

import queryString from 'query-string';

const parsed = queryString.parseUrl("https://pokeapi.co/api/v2/pokemon?offset=10&limit=10");

console.log(parsed.offset) will display 10

Here it's another approach :

function a(first,second)    
{        
return (second)(first);           
}     

a('Hello',function(e){alert(e+ ' world!');}); //=> Hello world     

Your linker (ld) obviously doesn't like the order in which make arranges the GCC arguments so you'll have to change your Makefile a bit:

CC=gcc
CFLAGS=-Wall
LDFLAGS=-lm

.PHONY: all
all: client

.PHONY: clean
clean:
    $(RM) *~ *.o client

OBJECTS=client.o
client: $(OBJECTS)
    $(CC) $(CFLAGS) $(OBJECTS) -o client $(LDFLAGS)

In the line defining the client target change the order of $(LDFLAGS) as needed.

The idea is to add fixed div to bottom. When virtual keyboard is shown/hidden scroll event occurs. Plus, we find out keyboard height

const keyboardAnchor = document.createElement('div')
keyboardAnchor.style.position = 'fixed'
keyboardAnchor.style.bottom = 0
keyboardAnchor.style.height = '1px'
document.body.append(keyboardAnchor)
        
window.addEventListener('scroll', ev => {
  console.log('keyboard height', window.innerHeight - keyboardAnchor.getBoundingClientRect().bottom)
}, true)

        
        

you need to use add class open in <div class="btn-group open">

and in li add class="active"

I don't know I used random.shuffle() but it return 'None' to me, so I wrote this, might helpful to someone

def shuffle(arr):
    for n in range(len(arr) - 1):
        rnd = random.randint(0, (len(arr) - 1))
        val1 = arr[rnd]
        val2 = arr[rnd - 1]

        arr[rnd - 1] = val1
        arr[rnd] = val2

    return arr

The documentation for this is good if not a little difficult to find.

Facebook Graph API - Page Tokens

After initializing node's fbgraph, you can run:

var facebookAccountID = yourAccountIdHere 

graph
.setOptions(options)
.get(facebookAccountId + "/accounts", function(err, res) {
  console.log(res); 
});

and receive a JSON response with the token you want to grab, located at:

res.data[0].access_token

If you want to assign a long str to variable, you can do it as below:

net_weights_pathname = (
    '/home/acgtyrant/BigDatas/'
    'model_configs/lenet_iter_10000.caffemodel')

Do not add any comma, or you will get a tuple which contains many strs!

I think that it should be:

$path = 'myfolder/myimage.png';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);

I agree with Greg that a two phase approach is a reasonable solution, however I would do it the other way around. I would do:

POST http://server/data/media
body:
{
    "Name": "Test",
    "Latitude": 12.59817,
    "Longitude": 52.12873
}

To create the metadata entry and return a response like:

201 Created
Location: http://server/data/media/21323
{
    "Name": "Test",
    "Latitude": 12.59817,
    "Longitude": 52.12873,
    "ContentUrl": "http://server/data/media/21323/content"
}

The client can then use this ContentUrl and do a PUT with the file data.

The nice thing about this approach is when your server starts get weighed down with immense volumes of data, the url that you return can just point to some other server with more space/capacity. Or you could implement some kind of round robin approach if bandwidth is an issue.

Use this code:

public bool roomSelected()
{
    foreach (RadioButton rb in GroupBox1.Controls)
    {
        if (rb.Checked == true)
        {
            return true;
        }
    }
    return false;
}

I managed to fix this by adding:

android:layout_marginTop="?android:attr/actionBarSize"

to the FrameLayout like so:

 <FrameLayout
        android:id="@+id/content"
        android:layout_marginTop="?android:attr/actionBarSize"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
       />

After many fruitful hours of exploring OCR libraries, bounding boxes and clustering algorithms - I found a solution so simple it makes you want to cry!

I hope you are using Linux;

pdftotext -layout NAME_OF_PDF.pdf

AMAZING!!

Now you have a nice text file with all the information lined up in nice columns, now it is trivial to format into a csv etc..

It is for times like this that I love Linux, these guys came up with AMAZING solutions to everything, and put it there for FREE!

Beware that file_get_contents solution doesn't close the connection as it should when a server returns Connection: close in the HTTP header.

CURL solution, on the other hand, terminates the connection so the PHP script is not blocked by waiting for a response.

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

 NSString * encodedString = (NSString *)CFURLCreateStringByAddingPercentEscapes(NUL,(CFStringRef)@"parameter",NULL,(CFStringRef)@"!*'();@&+$,/?%#[]~=_-.:",kCFStringEncodingUTF8 );

NSURL * url = [[NSURL alloc] initWithString:[@"address here" stringByAppendingFormat:@"?cid=%@",encodedString, nil]];

Below query will give accurate answer. Follow and give me comments:

select top 1 salary from (
select DISTINCT  top 3 salary from Table(table name) order by salary  ) as comp
order by personid salary 

You can disable sql_mode=only_full_group_by by some command you can try this by terminal or MySql IDE

mysql> set global sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

mysql> set session sql_mode='STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';

I have tried this and worked for me. Thanks :)

import com.sun.org.apache.xml.internal.serializer.OutputPropertiesFactory

You can use something called Dash: Offline API Documentation for Mac. For Windows and Linux you have an alternative called Zeal.

Both of them are very similar. And you can get offline documentation for most of the APIs out there like Java, android, Angular, HTML5 etc .. almost everything.

I have also written a post on How to install Zeal on Ubuntu 14.04

For all the Swift lovers out there, here is the answer by @Travis translated into SWIFT:

Do what @Travis explained before the Objective C code. Then,

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    var exampleViewController: ExampleViewController = mainStoryboard.instantiateViewControllerWithIdentifier("ExampleController") as! ExampleViewController

    self.window?.rootViewController = exampleViewController

    self.window?.makeKeyAndVisible()

    return true
}

The ExampleViewController would be the new initial view controller you would like to show.

The steps explained:

1. Create a new window with the size of the current window and set it as our main window
2. Instantiate a storyboard that we can use to create our new initial view controller
3. Instantiate our new initial view controller based on it's Storyboard ID
4. Set our new window's root view controller as our the new controller we just initiated
5. Make our new window visible

Enjoy and happy programming!

I had a similar problem. I got an exception "Type is not resolved for member 'Microsoft.IdentityModel.Claims.ClaimsPrincipal, Microsoft.IdentityModel, Version = 3.5.0.0, Culture = neutral, PublicKeyToken = 31bf3856ad364e35'.".

I tried to run the ASP.NET application from Visual Studio, which was a reference to a local copy of Microsoft.IdentityModel.dll.

I did not want to install the SDK and I had to copy the library to the directory "C: \ Program Files \ Common Files \ Microsoft Shared \ DevServer \ 10.0" and restart Visual Studio.

If your keys are dynamic I would suggest deserializing directly into a DataTable:

    class SampleData
    {
        [JsonProperty(PropertyName = "items")]
        public System.Data.DataTable Items { get; set; }
    }

    public void DerializeTable()
    {
        const string json = @"{items:["
            + @"{""Name"":""AAA"",""Age"":""22"",""Job"":""PPP""},"
            + @"{""Name"":""BBB"",""Age"":""25"",""Job"":""QQQ""},"
            + @"{""Name"":""CCC"",""Age"":""38"",""Job"":""RRR""}]}";
        var sampleData = JsonConvert.DeserializeObject<SampleData>(json);
        var table = sampleData.Items;

        // write tab delimited table without knowing column names
        var line = string.Empty;
        foreach (DataColumn column in table.Columns)            
            line += column.ColumnName + "\t";                       
        Console.WriteLine(line);

        foreach (DataRow row in table.Rows)
        {
            line = string.Empty;
            foreach (DataColumn column in table.Columns)                
                line += row[column] + "\t";                                   
            Console.WriteLine(line);
        }

        // Name   Age   Job    
        // AAA    22    PPP    
        // BBB    25    QQQ    
        // CCC    38    RRR    
    }

You can determine the DataTable column names and types dynamically once deserialized.

For me, I started the app from within windows explorer (by double clicking on it). Then it crashed immediately.

I then opened Event Viewer of windows and viewed Application and it displayed full stacktrace of error. The stacktrace showed relation with Bitmap or images. It was then turned out to be due to app icon not found

P3: lodsb  ; get the ASCII from the address in DS:SI + increase si
    stosb  ; write ASCII directly to the screen using ES:DI + increase di
    inc di ; step over attribut byte

In python 3 you can easily convert a byte string into a list of integers (0..255) by

>>> list(b'y\xcc\xa6\xbb')

Constructor looks like a method but name should be as class name and no return value.

Overriding means what we have declared in Super class, that exactly we have to declare in Sub class it is called Overriding. Super class name and Sub class names are different.

If you trying to write Super class Constructor in Sub class, then Sub class will treat that as a method not constructor because name should not match with Sub class name. And it will give an compilation error that methods does not have return value. So we should declare as void, then only it will compile.

My typical expectation is than when "subject" is used a context like this, it means the target of the certificate. If you think of a certificate as a cryptographically secured description of a thing (person, device, communication channel, etc), then the subject is the stuff related to that thing.

It's not the thing itself. For example, no one would say "the subject takes his SmartCard and authenticates his PIN". That would be the "user".

But it usually relates to the various data items related to that that thing. For example:

• Subject DN = Subject Distinguished Name = the unique identifier for what this thing is. Includes information about the thing being certified, including common name, organization, organization unit, country codes, etc.
• Subject Key = part (or all) of the certificate's private/public key pair. If it's coming from the certificate, it's the public key. If it's coming from a key store in a secure location, it's probably the private key. Either part of the key is the cryptographic data used by the thing that received the certificate.
• Subject certificate - the end point for the transaction - this is the thing requesting some secure capability - like integrity checking, authentication, privacy, etc.

Usually, it's used to distinguish between the other players in the PKI world. Namely the "issuer" and the "root". The issuer is the CA that issued the cert (to the subject), and the root is the CA that is end point of all the trust in the heirarchy. The typical relationship is root--->issuer--->subject.

Simplest solution:- I used xCode 7 and iOS 9.

in your .m

delete #import "VC.h"

save .m and link your outlet again it work fine.

android:autoLink="web" simply works if you have full links in your HTML. The following will be highlighted in blue and clickable:

New version (Visual Studio 0.3.0) support more multi cursor feature.

Multi-cursor
Here's multi-cursor improvements that we've made.

?D selects the word at the cursor, or the next occurrence of the current selection.
?K ?D moves the last added cursor to next occurrence of the current selection.
The two actions pick up the matchCase and matchWholeWord settings of the find widget.
?U undoes the last cursor action, so if you added one cursor too many or made a mistake, press ?U to return to the previous cursor state.
Insert cursor above (???) and insert cursor below (???) now reveals the last added cursor, making it easier to work with multi-cursors spanning more than one screen height (i.e., working with 300 lines while only 80 fit in the screen).

And short cut of select multi cursor change into cmd + d(it's same as Sublime Text. lol)

We can expect that next version supports more convenient feature about multi cursor ;)

Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want

x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)

WORD.C <- function(WORDS){
  require(wordcloud)

  L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))

  # Takes a dataframe and the text you want to display
  FUN <- function(X, text){
    windows() 
    wordcloud(X[, 1], X[, 2], min.freq=1)
    mtext(text, 3, padj=-4.5, col="red")  #what I'm trying that isn't working
  }

  # Now creates the sequence 1,...,length(L2)
  # Loops over that and then create an anonymous function
  # to send in the information you want to use.
  lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})

  # Since you asked about loops
  # you could use i in seq_along(L2) 
  # instead of 1:length(L2) if you wanted to
  #for(i in 1:length(L2)){
  #  FUN(L2[[i]], names(L2)[i])
  #}
}

WORD.C(list.xy)

You can use this approach too

module.exports.func1 = ...
module.exports.func2 = ...

or

exports.func1 = ...
exports.func2 = ...

This is how I solved this issue:

1. git pull origin master
2. git push origin master

This usually happens when your remote branch is not updated. And after this if you get an error like "Please enter a commit message" Refer to this ( For me xiaohu Wang answer worked :) )

I tried the first solution and it works but the end user can easily identify that the div's are refreshing as it is fadeIn(), without fade in i tried .toggle().toggle() and it works perfect. you can try like this

$("#panel").toggle().toggle();

it works perfectly for me as i'm developing a messenger and need to minimize and maximize the chat box's and this does it best rather than the above code.

A jQuery solution:

$("#frame1").ready( function() {

  $("#frame1").contents().scrollTop( $("#frame1").contents().scrollTop() + 10 );

});

PHP Code:

date_default_timezone_set('Asia/Kolkata');
$currentDateTime=date('m/d/Y H:i:s');
$newDateTime = date('h:i A', strtotime($currentDateTime));
echo $newDateTime; 

Output: 05:03 PM

I don't think it's necessary to use semi-quotes around the variables, try:

curl -XPOST 'http://localhost/Service' -d "path=%2fxyz%2fpqr%2ftest%2f&fileName=1.doc"

%2f is the escape code for a /.

Also, do you need to specify a port? ( just checking :) )

For SQL Server 2012, using Sql Server Management Studio, I found these steps from the Microsoft page useful to restore to a different database file and name: (ref: http://technet.microsoft.com/en-us/library/ms175510.aspx)

Note steps 4 and 7 are important to set so as not to overwrite the existing database.

To restore a database to a new location, and optionally rename the database

1. Connect to the appropriate instance of the SQL Server Database Engine, and then in Object Explorer, click the server name to expand the server tree.
2. Right-click Databases, and then click Restore Database. The Restore Database dialog box opens.

3. On the General page, use the Source section to specify the source and location of the backup sets to restore. Select one of the following options:

   • Database

     • Select the database to restore from the drop-down list. The list contains only databases that have been backed up according to the msdb backup history.

       Note If the backup is taken from a different server, the destination server will not have the backup history information for the specified database. In this case, select Device to manually specify the file or device to restore.

   • Device

     • Click the browse (...) button to open the Select backup devices dialog box. In the Backup media type box, select one of the listed device types. To select one or more devices for the Backup media box, click Add. After you add the devices you want to the Backup media list box, click OK to return to the General page. In the Source: Device: Database list box, select the name of the database which should be restored.

       Note This list is only available when Device is selected. Only databases that have backups on the selected device will be available.

4. In the Destination section, the Database box is automatically populated with the name of the database to be restored. To change the name of the database, enter the new name in the Database box.
5. In the Restore to box, leave the default as To the last backup taken or click on Timeline to access the Backup Timeline dialog box to manually select a point in time to stop the recovery action.
6. In the Backup sets to restore grid, select the backups to restore. This grid displays the backups available for the specified location. By default, a recovery plan is suggested. To override the suggested recovery plan, you can change the selections in the grid. Backups that depend on the restoration of an earlier backup are automatically deselected when the earlier backup is deselected.
7. To specify the new location of the database files, select the Files page, and then click Relocate all files to folder. Provide a new location for the Data file folder and Log file folder. Alternatively you can keep the same folders and just rename the database and log file names.

In case you want to apply the shadow to the inside of the element (inset) but only want it to appear on one single side you can define a negative value to the "spread" parameter (5th parameter in the second example).

To completely remove it, make it the same size as the shadows blur (4th parameter in the second example) but as a negative value.

Also remember to add the offset to the y-position (3rd parameter in the second example) so that the following:

box-shadow:         inset 0px 4px 3px rgba(50, 50, 50, 0.75);

becomes:

box-shadow:         inset 0px 7px 3px -3px rgba(50, 50, 50, 0.75);

Check this updated fiddle: http://jsfiddle.net/FrEnY/1282/ and more on the box-shadow parameters here: http://www.w3schools.com/cssref/css3_pr_box-shadow.asp

According to the docs, it's preferable to omit the closing tag if it's at the end of the file for the following reason:

If a file is pure PHP code, it is preferable to omit the PHP closing tag at the end of the file. This prevents accidental whitespace or new lines being added after the PHP closing tag, which may cause unwanted effects because PHP will start output buffering when there is no intention from the programmer to send any output at that point in the script.

OpenMP is supported on many platforms (including Visual Studio 2005) and it offers a

int omp_get_num_procs();

function that returns the number of processors/cores available at the time of call.

I had the same issue. It seems the easiest solution is to just remove the remote, readd it, and fetch.

Another way to do this (in modern browsers) is with a negative spread box-shadow. Check out this updated fiddle: http://jsfiddle.net/WuZat/290/

box-shadow: 0px 24px 3px -24px magenta;

I think the safest and most compatible way is the accepted answer above, though. Just thought I'd share another technique.

If the execution planner says they're the same, they're the same. Use whichever one will make your intention more obvious -- in this case, the second.

Use a trap!

tempfiles=( )
cleanup() {
  rm -f "${tempfiles[@]}"
}
trap cleanup 0

error() {
  local parent_lineno="$1"
  local message="$2"
  local code="${3:-1}"
  if [[ -n "$message" ]] ; then
    echo "Error on or near line ${parent_lineno}: ${message}; exiting with status ${code}"
  else
    echo "Error on or near line ${parent_lineno}; exiting with status ${code}"
  fi
  exit "${code}"
}
trap 'error ${LINENO}' ERR

...then, whenever you create a temporary file:

temp_foo="$(mktemp -t foobar.XXXXXX)"
tempfiles+=( "$temp_foo" )

and $temp_foo will be deleted on exit, and the current line number will be printed. (set -e will likewise give you exit-on-error behavior, though it comes with serious caveats and weakens code's predictability and portability).

You can either let the trap call error for you (in which case it uses the default exit code of 1 and no message) or call it yourself and provide explicit values; for instance:

error ${LINENO} "the foobar failed" 2

will exit with status 2, and give an explicit message.

An alternative approach may be to embed images in the email using the cid method. (Basically including the image as an attachment, and then embedding it). In my experience, this approach seems to be well supported these days.

I think currently the application-context.xml file is into src/main/resources AND the social.properties file is into src/main/java... so when you package (mvn package) or when you run tomcat (mvn tomcat:run) your social.properties disappeared (I know you said when you checked into the .war the files are here... but your exception says the opposite).

The solution is simply to put all your configuration files (application-context.xml and social.properties) into src/main/resources to follow the maven standard structure.

You can do it, but it's not pretty:

#include <iostream>

class A {
    int mvalue;
public:
    A(int value) : mvalue(value) {}
    int value() { return mvalue; }
};

class B {
    // TODO: hack that respects alignment of A.. maybe C++14's alignof?
    char _hack[sizeof(A[3])];
    A* marr;
public:
    B() : marr(reinterpret_cast<A*>(_hack)) {
        new (&marr[0]) A(5);
        new (&marr[1]) A(6);
        new (&marr[2]) A(7);
    }

    A* arr() { return marr; }
};

int main(int argc, char** argv) {
    B b;
    A* arr = b.arr();
    std::cout << arr[0].value() << " " << arr[1].value() << " " << arr[2].value() << "\n";
    return 0;
}

If you put this in your code, I hope you have a VERY good reason.

For HeidiSQL users:

If you use HeidiSQL, you can select the row(s) you wish to get insert statement. Then right click > Export grid rows > select "Copy to clipboard" for "Output target", "Selection" for "Row Selection" so you don't export other rows, "SQL INSERTs" for "Output format" > Click OK.

The insert statement will be inside you clipboard.

Just in case if anyone reached here looking for solution, here is how i resolved it. By mistake I deleted all files from my server ( bin directory ) but when i recopied all files i missed App_global.asax.dll and App_global.asax.compiled files. Because these files were missing IIS was giving me this error

403 - Forbidden: Access is denied.

As soon as i added these files, it started working perfectly fine.

SELECT <select_list> 
FROM Table_A A
LEFT JOIN Table_B B
ON A.Key = B.Key
WHERE B.Key IS NULL

The fact that your method does not use the self argument (which is a reference to the instance that the method is attached to) doesn't mean you can leave it out. It always has to be there, because Python is always going to try to pass it in.

I think this is a very useful question with good answer. Just to add my two cents from the MSDN Create a Login page:

A login is a security principal, or an entity that can be authenticated by a secure system. Users need a login to connect to SQL Server. You can create a login based on a Windows principal (such as a domain user or a Windows domain group) or you can create a login that is not based on a Windows principal (such as an SQL Server login).

Note:
To use SQL Server Authentication, the Database Engine must use mixed mode authentication. For more information, see Choose an Authentication Mode.

As a security principal, permissions can be granted to logins. The scope of a login is the whole Database Engine. To connect to a specific database on the instance of SQL Server, a login must be mapped to a database user. Permissions inside the database are granted and denied to the database user, not the login. Permissions that have the scope of the whole instance of SQL Server (for example, the CREATE ENDPOINT permission) can be granted to a login.

I'm think this has been answered before...but anyway, if you want to encrypt/decrypt data, you can't use SHA256

//Key
$key = 'SuperSecretKey';

//To Encrypt:
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, 'I want to encrypt this', MCRYPT_MODE_ECB);

//To Decrypt:
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $encrypted, MCRYPT_MODE_ECB);

<form name="loginform" onsubmit="validateForm()">

instead of putting the onsubmit on the actual input button

ORA-01031: insufficient privileges Solution: Go to Your System User. then Write This Code:

you can use framelayout to achieve this.

how to use framelayout

   android:layout_width="fill_parent"
   android:layout_height="fill_parent">

   <ImageView 
   android:src="@drawable/ic_launcher"
   android:scaleType="fitCenter"
   android:layout_height="250px"

   android:textStyle="bold"
   android:layout_height="fill_parent"
   android:layout_width="fill_parent"
   android:gravity="center"/>
</FrameLayout>

ref: tutorialspoint

From here:

// when the DOM is ready
$(function () {
  var img = new Image();
  // wrap our new image in jQuery, then:
  $(img)
    // once the image has loaded, execute this code
    .load(function () {
      // set the image hidden by default    
      $(this).hide();
      // with the holding div #loader, apply:
      $('#loader')
        // remove the loading class (so no background spinner), 
        .removeClass('loading')
        // then insert our image
        .append(this);
      // fade our image in to create a nice effect
      $(this).fadeIn();
    })
    // if there was an error loading the image, react accordingly
    .error(function () {
      // notify the user that the image could not be loaded
    })
    // *finally*, set the src attribute of the new image to our image
    .attr('src', 'images/headshot.jpg');
});

This will show you clues about why the linker doesn't want the installed library:

I had the same problem in a different context: my system /lib/libz.so.1 had unsatisfied dependencies on libc because I was trying to relink on a different version of the OS.

While you should generally prefer sys.exit because it is more "friendly" to other code, all it actually does is raise an exception.

If you are sure that you need to exit a process immediately, and you might be inside of some exception handler which would catch SystemExit, there is another function - os._exit - which terminates immediately at the C level and does not perform any of the normal tear-down of the interpreter; for example, hooks registered with the "atexit" module are not executed.

Sybase has the same case syntax as SQL Server:

Description

Supports conditional SQL expressions; can be used anywhere a value expression can be used.

Syntax

case 
     when search_condition then expression 
    [when search_condition then expression]...
    [else expression]
end

Case and values syntax

case expression
     when expression then expression 
    [when expression then expression]...
    [else expression]
end

Parameters

case

begins the case expression.

when

precedes the search condition or the expression to be compared.

search_condition

is used to set conditions for the results that are selected. Search conditions for case expressions are similar to the search conditions in a where clause. Search conditions are detailed in the Transact-SQL User’s Guide.

then

precedes the expression that specifies a result value of case.

expression

is a column name, a constant, a function, a subquery, or any combination of column names, constants, and functions connected by arithmetic or bitwise operators. For more information about expressions, see “Expressions” in.

Example

select disaster, 
       case
            when disaster = "earthquake" 
                then "stand in doorway"
            when disaster = "nuclear apocalypse" 
                then "hide in basement"
            when monster = "zombie apocalypse" 
                then "hide with Chuck Norris"
            else
                then "ask mom"
       end

$name -replace ";*",""

You were close, but you used the syntax of a wildcard expresson rather than a regular expression, which is what the -replace operator expects.

Therefore (hash sequence shortened):

PS> 'test.txt ; 131 136 80 89 119 17 60 123 210 121 188' -replace '\s*;.*'
test.txt

Note:

• Omitting the substitution-text operand (the 2nd RHS operand) implicitly uses "" (the empty string), i.e. it effectively removes what the regex matched.

• .* is what represents a potentially empty run (*) of characters (.) in a regex - it is the regex equivalent of * by itself in a wildcard expression.

• Adding \s* before the ; in the regex also removes trailing whitespace (\s) after the filename.

• I've used '...' rather than "..." to enclose the regex, so as to prevent confusion between what PowerShell expands up front (see expandable strings in PowerShell and what the .NET regex engine sees.

For very large files I'd do something like this

string tempFile = Path.GetTempFileName();

using(var sr = new StreamReader("file.txt"))
using(var sw = new StreamWriter(tempFile))
{
    string line;

    while((line = sr.ReadLine()) != null)
    {
         if(line != "removeme")
             sw.WriteLine(line);
    }
}

File.Delete("file.txt");
File.Move(tempFile, "file.txt");

Update I originally wrote this back in 2009 and I thought it might be interesting with an update. Today you could accomplish the above using LINQ and deferred execution

var tempFile = Path.GetTempFileName();
var linesToKeep = File.ReadLines(fileName).Where(l => l != "removeme");

File.WriteAllLines(tempFile, linesToKeep);

File.Delete(fileName);
File.Move(tempFile, fileName);

The code above is almost exactly the same as the first example, reading line by line and while keeping a minimal amount of data in memory.

A disclaimer might be in order though. Since we're talking about text files here you'd very rarely have to use the disk as an intermediate storage medium. If you're not dealing with very large log files there should be no problem reading the contents into memory instead and avoid having to deal with the temporary file.

File.WriteAllLines(fileName, 
    File.ReadLines(fileName).Where(l => l != "removeme").ToList());

Note that The .ToList is crucial here to force immediate execution. Also note that all the examples assume the text files are UTF-8 encoded.

No, It is not possible. But if you want to dig it more, then you can visit Using Android phone as GSM Gateway for VoIP where author has concluded that

It's not possible to use Android as a GSM Gateway in its current form. Even after flashing custom ROM because they also depends on proprietary RIL (Radio Interface Layer) firmwares. Hurdles 1 and 2 (API limitation) can be removed because the source code is available for the open source community to make it possible. However, the hurdle 3 (proprietary RIL) is dependent on the hardware vendors. Hardware vendors do not usually make their device drivers code available.

Trivial as it may seem in my case netbeans version maven project 7.2.1 was different. There is a folder in the project called dependencies. Right click and then it brings up a popup window where you can search for packages. In the query area put

mysql-connector

It will bring up the matches (it seems it does this against some repository). Double click then install.

I like to use text-shadow instead. Especially because you can use transitions to animate text-shadow.

All you really need is:

}

This answers a different question:

If trying to figure out if an OBJECT (not class) has a property,

OBJECT.GetType().GetProperty("PROPERTY") != null

returns true if (but not only if) the property exists.

In my case, I was in an ASP.NET MVC Partial View and wanted to render something if either the property did not exist, or the property (boolean) was true.

@if ((Model.GetType().GetProperty("AddTimeoffBlackouts") == null) ||
        Model.AddTimeoffBlackouts)

helped me here.

Edit: Nowadays, it's probably smart to use the nameof operator instead of the stringified property name.

maybe something like this:

foreach (var keyvaluepair in dict)
{
    if(Object.ReferenceEquals(keyvaluepair.Value, searchedObject))
    {
        //dict.Remove(keyvaluepair.Key);
        break;
    }
}

This isn't strictly an answer to your question about installing .gem packages, but you can specify all kinds of locations on a gem-by-gem basis by editing your Gemfile.

Specifying a :path attribute will install the gem from that path on your local machine.

gem "foreman", path: "/Users/pje/my_foreman_fork"

Alternately, specifying a :git attribute will install the gem from a remote git repository.

gem "foreman", git: "git://github.com/pje/foreman.git"

# ...or at a specific SHA-1 ref
gem "foreman", git: "git://github.com/pje/foreman.git", ref: "bf648a070c"

# ...or branch
gem "foreman", git: "git://github.com/pje/foreman.git", branch: "jruby"

# ...or tag
gem "foreman", git: "git://github.com/pje/foreman.git", tag: "v0.45.0"

(As @JHurrah mentioned in his comment.)

I had simillar issue with maven tests on x86 linux which i was using in terminal. I was logging in to linux by ssh. I started my java selenium tests by

mvn -DargLine="-Dbaseurl=http://http://127.0.0.1:8080/web/" install

Excepting my app, after running these tests I received error in logs:

unknown error: Chrome failed to start: exited abnormally

I was running these tests as root user. Before this error i received that ChromeDriver is nor present. I moved forward with this by installing ChromeDriver binary and adding it to PATH. But then i had to install google-chrome browser - ChromeDriver alone isn't enough to run tests. So the mistake is problem maybe with screen buffer in terminal window, but You can install Xvfb which is virtual screen buffer. What is important, that you should run your tests not as root, because you may receive another Chrome Browser error. So no as root i run:

export DISPLAY=:99
Xvfb :99 -ac -screen 0 1280x1024x24 &

What is important here, that in my case the number related to DISPLAY ought to be same as Xvfb :NN parameter. 99 in that case. I had another problem because i ran Xvfb with another DISPLAY value and I wanted it to stop. In order to restart Xvfb:

ps -aux | grep Xvfb
kill -9 PID
sudo rm /tmp/.X11-unix/X99

So find a process PID with grep. Kill Xvfb process. And then there is lock in /tmp/.X11-unix/XNN , so delete this lock and you can start server again. If You run not as root, set simillar displays, install google-chrome then with maven you can start selenium tests. My tests went fine with these rules and operations.

You could use find instead:

find . -name '*.txt'

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

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

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

At original time of writing to uninstall:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall)"

Edit: As of 2020 to uninstall:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/uninstall.sh)"

I firstly recommend you to read Hannes Dorfmann's great article about this topic.

When new view type comes, you have to edit your adapter and you have to handle so many mess things. Your adapter should be Open for extension but Closed for modification.

You may check this two project, they can give the idea about how to handle different ViewTypes in Adapter:

Auto Refresh Workbook for example every 5 sec. Apply to module

Public Sub Refresh()
'refresh
ActiveWorkbook.RefreshAll

alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
    Application.OnTime alertTime, "Refresh"

End Sub

Apply to Workbook on Open

Private Sub Workbook_Open()
alertTime = Now + TimeValue("00:00:05") 'hh:mm:ss
Application.OnTime alertTime, "Refresh"
End Sub

:)

You can use the DataFrame.select method:

In [1]: df = pd.DataFrame([[1,2],[3,4]], index=['A','B'])

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

In [3]: L = ['A']

In [4]: df.select(lambda x: x in L)
Out[4]: 
   0  1
A  1  2

I had the same problem. My code below didn't work, but when I replaced the last "if" with "else", it works. The error was: may reach end of non-void function.

int shifted(char key_letter)
  {
        if(isupper(key_letter))
        {
            return key_letter - 'A'; 
        }

        if(islower(key_letter)   //<----------- doesn't work, replace with else

        {                                            


            return key_letter - 'a'; 
        }

  }

Here's a quick way to get what is happening:

When you did the following:

name? : string

You were saying to TypeScript it was optional. Nevertheless, when you did:

let name1 : string = person.name; //<<<Error here 

You did not leave it a choice. You needed to have a Union on it reflecting the undefined type:

let name1 : string | undefined = person.name; //<<<No error here 

Using your answer, I was able to sketch out the following which is basically, an Interface, a Class and an Object. I find this approach simpler, never mind if you don't.

// Interface
interface iPerson {
    fname? : string,
    age? : number,
    gender? : string,
    occupation? : string,
    get_person?: any
}

// Class Object
class Person implements iPerson {
    fname? : string;
    age? : number;
    gender? : string;
    occupation? : string;
    get_person?: any = function () {
        return this.fname;
    }
}

// Object literal
const person1 : Person = {
    fname : 'Steve',
    age : 8,
    gender : 'Male',
    occupation : 'IT'  
}

const p_name: string | undefined = person1.fname;

// Object instance 
const person2: Person = new Person();
person2.fname = 'Steve';
person2.age = 8;
person2.gender = 'Male';
person2.occupation = 'IT';

// Accessing the object literal (person1) and instance (person2)
console.log('person1 : ', p_name);
console.log('person2 : ', person2.get_person());

Can you write virtual functions in Java?

Yes. In fact, all instance methods in Java are virtual by default. Only certain methods are not virtual:

• Class methods (because typically each instance holds information like a pointer to a vtable about its specific methods, but no instance is available here).
• Private instance methods (because no other class can access the method, the calling instance has always the type of the defining class itself and is therefore unambiguously known at compile time).

Here are some examples:

"Normal" virtual functions

The following example is from an old version of the wikipedia page mentioned in another answer.

import java.util.*;

public class Animal 
{
   public void eat() 
   { 
      System.out.println("I eat like a generic Animal."); 
   }

   public static void main(String[] args) 
   {
      List<Animal> animals = new LinkedList<Animal>();

      animals.add(new Animal());
      animals.add(new Fish());
      animals.add(new Goldfish());
      animals.add(new OtherAnimal());

      for (Animal currentAnimal : animals) 
      {
         currentAnimal.eat();
      }
   }
}

class Fish extends Animal 
{
   @Override
   public void eat() 
   { 
      System.out.println("I eat like a fish!"); 
   }
}

class Goldfish extends Fish 
{
   @Override
   public void eat() 
   { 
      System.out.println("I eat like a goldfish!"); 
   }
}

class OtherAnimal extends Animal {}

Output:

I eat like a generic Animal.
I eat like a fish!
I eat like a goldfish!
I eat like a generic Animal.

Example with virtual functions with interfaces

Java interface methods are all virtual. They must be virtual because they rely on the implementing classes to provide the method implementations. The code to execute will only be selected at run time.

For example:

interface Bicycle {         //the function applyBrakes() is virtual because
    void applyBrakes();     //functions in interfaces are designed to be 
}                           //overridden.

class ACMEBicycle implements Bicycle {
    public void applyBrakes(){               //Here we implement applyBrakes()
       System.out.println("Brakes applied"); //function
    }
}

Example with virtual functions with abstract classes.

Similar to interfaces Abstract classes must contain virtual methods because they rely on the extending classes' implementation. For Example:

abstract class Dog {                   
    final void bark() {               //bark() is not virtual because it is 
        System.out.println("woof");   //final and if you tried to override it
    }                                 //you would get a compile time error.

    abstract void jump();             //jump() is a "pure" virtual function 
}                                     
class MyDog extends Dog{
    void jump(){
        System.out.println("boing");    //here jump() is being overridden
    }                                  
}
public class Runner {
    public static void main(String[] args) {
        Dog dog = new MyDog();       // Create a MyDog and assign to plain Dog variable
        dog.jump();                  // calling the virtual function.
                                     // MyDog.jump() will be executed 
                                     // although the variable is just a plain Dog.
    }
}

This SQL query gives output similar to \dx:

SELECT e.extname AS "Name", e.extversion AS "Version", n.nspname AS "Schema", c.description AS "Description" 
FROM pg_catalog.pg_extension e 
LEFT JOIN pg_catalog.pg_namespace n ON n.oid = e.extnamespace 
LEFT JOIN pg_catalog.pg_description c ON c.objoid = e.oid AND c.classoid = 'pg_catalog.pg_extension'::pg_catalog.regclass 
ORDER BY 1;

Thanks to https://blog.dbi-services.com/listing-the-extensions-available-in-postgresql/

One other thing that affected me: If you have multiple test devices, make sure you are making changes to the layout used by the device. In my case, I spent a while making changes to xmls in the "layout" directory until I discovered that my larger phone (which I switched to halfway through testing) was using xmls in the "layout-sw360dp" directory. Grrr!

You could do it like this.

jsFiddle

JS

var select = document.getElementById('mySelect');
select.onchange = function () {
    select.className = this.options[this.selectedIndex].className;
}

CSS

.redText {
    background-color:#F00;
}
.greenText {
    background-color:#0F0;
}
.blueText {
    background-color:#00F;
}

You could use option { background-color: #FFF; } if you want the list to be white.

HTML

<select id="mySelect" class="greenText">
    <option class="greenText" value="apple" >Apple</option>
    <option class="redText"   value="banana" >Banana</option>
    <option class="blueText" value="grape" >Grape</option>
</select>

Since this is a select it doesn't really make sense to use .yellowText as none selected if that's what you were getting at as something must be selected.

The two methods are 100% equivalent.

I’m not sure why Microsoft felt the need to include this extra Clear method but since it’s there, I recommend using it, as it clearly expresses its purpose.

The first question is what are your needs? UTF-8 encoding is a pretty good compromise between taking text created with a cheap editor and support for a wide variety of languages. In regards to the browser identifying the encoding, the response (from the web server) should tell the browser the encoding. Still most browsers will attempt to guess, because this is either missing or wrong in so many cases. They guess by reading some amount of the result stream to see if there is a character that does not fit in the default encoding. Currently all browser(? I did not check this, but it is pretty close to true) use utf-8 as the default.

So use utf-8 unless you have a compelling reason to use one of the many other encoding schemes.

Serhii's suggestion works and here is some more detail.

If you look in your installation's bin directory you will see catalina.sh or .bat scripts. If you look in these you will see that they run a setenv.sh or setenv.bat script respectively, if it exists, to set environment variables. The relevant environment variables are described in the comments at the top of catalina.sh/bat. To use them create, for example, a file $CATALINA_HOME/bin/setenv.sh with contents

export JAVA_OPTS="-server -Xmx512m"

For Windows you will need, in setenv.bat, something like

set JAVA_OPTS=-server -Xmx768m

Hope this helps, Glenn

If this is from a SQL Server datebase you could issue this kind of query...

Select Top 1 DepartureTime From TrainSchedule where DepartureTime > 
GetUTCDate()
Order By DepartureTime ASC

GetDate() could also be used, not sure how dates are being stored.

I am not sure how the data is being stored and/or read.

On a Mac, you need to use this command:

STATIC_DEPS=true sudo pip install lxml

Windows 10

This is basically @lengxuehx's answer, but updated for Win 10, and it assumes your bash installation is from Git Bash for Windows from git's official downloads.

cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

I ended up using this after I lost my context-menu items for Git Bash as my command to run from the registry settings. In case you're curious about that, I did this:

1. Create a new key called Bash in the shell key at HKEY_CLASSES_ROOT\Directory\Background\shell
2. Add a string value to Icon (not a new key!) that is the full path to your git-bash.exe, including the git-bash.exe part. You might need to wrap this in quotes.
3. Edit the default value of Bash to the text you want to use in the context menu
4. Add a sub-key to Bash called command
5. Modify command's default value to cmd /c (start /b "%cd%" "C:\Program Files\GitW\git-bash.exe") && exit

Then you should be able to close the registry and start using Git Bash from anywhere that's a real directory. For example, This PC is not a real directory.

In C++11, you can do this as a one-liner with a call to regex_replace:

#include <string>
#include <regex>

using std::string;

string do_replace( string const & in, string const & from, string const & to )
{
  return std::regex_replace( in, std::regex(from), to );
}

string test = "Remove all spaces";
std::cout << do_replace(test, " ", "") << std::endl;

output:

Removeallspaces

The short version is, call stmt.setFetchSize(50); and conn.setAutoCommit(false); to avoid reading the entire ResultSet into memory.

Here's what the docs say:

Getting results based on a cursor

By default the driver collects all the results for the query at once. This can be inconvenient for large data sets so the JDBC driver provides a means of basing a ResultSet on a database cursor and only fetching a small number of rows.

A small number of rows are cached on the client side of the connection and when exhausted the next block of rows is retrieved by repositioning the cursor.

Note:

• Cursor based ResultSets cannot be used in all situations. There a number of restrictions which will make the driver silently fall back to fetching the whole ResultSet at once.

• The connection to the server must be using the V3 protocol. This is the default for (and is only supported by) server versions 7.4 and later.-

• The Connection must not be in autocommit mode. The backend closes cursors at the end of transactions, so in autocommit mode the backend will have closed the cursor before anything can be fetched from it.-

• The Statement must be created with a ResultSet type of ResultSet.TYPE_FORWARD_ONLY. This is the default, so no code will need to be rewritten to take advantage of this, but it also means that you cannot scroll backwards or otherwise jump around in the ResultSet.-

• The query given must be a single statement, not multiple statements strung together with semicolons.

Example 5.2. Setting fetch size to turn cursors on and off.

Changing code to cursor mode is as simple as setting the fetch size of the Statement to the appropriate size. Setting the fetch size back to 0 will cause all rows to be cached (the default behaviour).

// make sure autocommit is off
conn.setAutoCommit(false);
Statement st = conn.createStatement();

// Turn use of the cursor on.
st.setFetchSize(50);
ResultSet rs = st.executeQuery("SELECT * FROM mytable");
while (rs.next()) {
   System.out.print("a row was returned.");
}
rs.close();

// Turn the cursor off.
st.setFetchSize(0);
rs = st.executeQuery("SELECT * FROM mytable");
while (rs.next()) {
   System.out.print("many rows were returned.");
}
rs.close();

// Close the statement.
st.close();

This is what I am going to use based on marc_s answer:

SELECT 
SUBSTRING(DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)'),PATINDEX('%NORTH%',DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)')) - 20,999)

FROM WEBPAGECONTENT 
WHERE COALESCE(PATINDEX('%NORTH%',DATA.value('(/PAGECONTENT/TEXT)[1]', 'VARCHAR(100)')),0) > 0

Return a substring on the search where the search criteria exists

If you want know, the how may nodejs processes running then you can use this command

ps -aef | grep node

So it will give list of nodejs process with it's project name. It will be helpful when you are running multipe nodejs application & you want kill specific process for the specific project.

Above command will give output like

XXX  12886  1741  1 12:36 ?        00:00:05 /home/username/.nvm/versions/node/v9.2.0/bin/node --inspect-brk=43443 /node application running path.

So to kill you can use following command

kill -9 12886

So it will kill the spcefic node process

I know this is an old thread, but I wanted to post my 2 cents...

Using Javascript you can achieve this without using $_POST, and thus avoid reloading the page..

<script>
function ButtonPressed()
{
window.location='index.php?view=next'; //this will set $_GET['view']='next'
}
</script>

<button type='button' onClick='ButtonPressed()'>Click me!</button>

<?PHP
 if(isset($_GET['next']))
    {
          echo "This will display after pressing the 'Click Me' button!";
    }
 ?>

The top rated answer by Tim Down provides the best solution I can see for conversion to RGB. I like this solution for Hex conversion better though because it provides the most succinct bounds checking and zero padding for conversion to Hex.

function RGBtoHex (red, green, blue) {
  red = Math.max(0, Math.min(~~this.red, 255));
  green = Math.max(0, Math.min(~~this.green, 255));
  blue = Math.max(0, Math.min(~~this.blue, 255));

  return '#' + ('00000' + (red << 16 | green << 8 | blue).toString(16)).slice(-6);
};

The use of left shift '<<' and or '|' operators make this a fun solution too.

Try an OUTER APPLY

SELECT 
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
FROM 
    tbl_Contents C
    OUTER APPLY
    (
        SELECT TOP 1 *
        FROM tbl_Media M 
        WHERE M.Content_Id = C.Content_Id 
    ) m
ORDER BY 
    C.Content_DatePublished ASC

Alternatively, you could GROUP BY the results

SELECT 
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
FROM 
    tbl_Contents C
    LEFT OUTER JOIN tbl_Media M ON M.Content_Id = C.Content_Id 
GROUP BY
    C.Content_ID,
    C.Content_Title,
    C.Content_DatePublished,
    M.Media_Id
ORDER BY
    C.Content_DatePublished ASC

The OUTER APPLY selects a single row (or none) that matches each row from the left table.

The GROUP BY performs the entire join, but then collapses the final result rows on the provided columns.

Solution with lodash library:

_.find(example) // => {name: "foo1"}

but there is no guarantee of the object properties internal storage order because it depends on javascript VM implementation.

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

I prefer using function pointers over gigantic switch statements, but in contrast to qrdl's answer I normally don't use explicit return codes or transition tables.

Also, in most cases you'll want a mechanism to pass along additional data. Here's an example state machine:

#include <stdio.h>

struct state;
typedef void state_fn(struct state *);

struct state
{
    state_fn * next;
    int i; // data
};

state_fn foo, bar;

void foo(struct state * state)
{
    printf("%s %i\n", __func__, ++state->i);
    state->next = bar;
}

void bar(struct state * state)
{
    printf("%s %i\n", __func__, ++state->i);
    state->next = state->i < 10 ? foo : 0;
}

int main(void)
{
    struct state state = { foo, 0 };
    while(state.next) state.next(&state);
}

I myself work in a heavily restricted server environment and unfortunately none of the solutions here are working for me. There may be no glove solution that fits all, but I figured out a swift workaround by reading the terminal output of pip freeze within my script and storing the modules labels and versions in a dictionary.

import os
os.system('pip freeze > tmpoutput')
with open('tmpoutput', 'r') as f:
    modules_version = f.read()
  
module_dict = {item.split("==")[0]:item.split("==")[-1] for item in modules_versions.split("\n")}

Retrieve your module's versions through passing the module label key, e.g.:

>>  module_dict["seaborn"]
'0.9.0'

Iam using Catalina and use this mysql_secure_installation command and now works for me:

$ mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): << enter root here >>

i enter root as current password

OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

and do the rest

You can look at phpinfo() or check if any of the functions of memcache is available. Ultimately, check whether the Memcache class exists or not.

e.g.

if(class_exists('Memcache')){
  // Memcache is enabled.
}

To do links, you can do

.social h2 a:link {
  color: pink;
  font-size: 14px;   
}

You can change the hover, visited, and active link styling too. Just replace "link" with what you want to style. You can learn more at the w3schools page CSS Links.

You may use as following to get Height and Weight of an Numpy array:

int height = arr.shape[0]
int weight = arr.shape[1]

If your array has multiple dimensions, you can increase the index to access them.

Try:

Iterator<Map.Entry<String,String>> iter = testMap.entrySet().iterator();
while (iter.hasNext()) {
    Map.Entry<String,String> entry = iter.next();
    if("Sample".equalsIgnoreCase(entry.getValue())){
        iter.remove();
    }
}

With Java 1.8 and onwards you can do the above in just one line:

testMap.entrySet().removeIf(entry -> "Sample".equalsIgnoreCase(entry.getValue()));

Some numpy functions for how to control the rounding: rint, floor,trunc, ceil. depending how u wish to round the floats, up, down, or to the nearest int.

>>> x = np.array([[1.0,2.3],[1.3,2.9]])
>>> x
array([[ 1. ,  2.3],
       [ 1.3,  2.9]])
>>> y = np.trunc(x)
>>> y
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> z = np.ceil(x)
>>> z
array([[ 1.,  3.],
       [ 2.,  3.]])
>>> t = np.floor(x)
>>> t
array([[ 1.,  2.],
       [ 1.,  2.]])
>>> a = np.rint(x)
>>> a
array([[ 1.,  2.],
       [ 1.,  3.]])

To make one of this in to int, or one of the other types in numpy, astype (as answered by BrenBern):

a.astype(int)
array([[1, 2],
       [1, 3]])

>>> y.astype(int)
array([[1, 2],
       [1, 2]])

you can use this code as template please customize it as per your requirement.

DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

You can use all

> all(1:6 %in% 0:36)
[1] TRUE
> all(1:60 %in% 0:36)
[1] FALSE

On a similar note, if you want to check whether any of the elements is TRUE you can use any

> any(1:6 %in% 0:36)
[1] TRUE
> any(1:60 %in% 0:36)
[1] TRUE
> any(50:60 %in% 0:36)
[1] FALSE

Use the following simple way to interactively get user data by a prompt as Arguments on what you want.

Version : Python 3.X

name = input('Enter Your Name: ')
print('Hello ', name)

For me the issue resolved when i updated the appcompact v7 to latest..

compile 'com.android.support:appcompat-v7:25.3.0'

Hope it helps...:)

For directories dirname gets tripped for ../ and returns ./.

nolan6000's function can be modified to fix that:

get_abs_filename() {
  # $1 : relative filename
  if [ -d "${1%/*}" ]; then
    echo "$(cd ${1%/*}; pwd)/${1##*/}"
  fi
}

You can now do this with Lambda@Edge to rewrite the paths

Here is a working lambda@Edge function:

1. Create a new Lambda function, but use one of the pre-existing Blueprints instead of a blank function.
2. Search for “cloudfront” and select cloudfront-response-generation from the search results.
3. After creating the function, replace the content with the below. I also had to change the node runtime to 10.x because cloudfront didn't support node 12 at the time of writing.

'use strict';
exports.handler = (event, context, callback) => {

    // Extract the request from the CloudFront event that is sent to Lambda@Edge 
    var request = event.Records[0].cf.request;

    // Extract the URI from the request
    var olduri = request.uri;

    // Match any '/' that occurs at the end of a URI. Replace it with a default index
    var newuri = olduri.replace(/\/$/, '\/index.html');

    // Log the URI as received by CloudFront and the new URI to be used to fetch from origin
    console.log("Old URI: " + olduri);
    console.log("New URI: " + newuri);

    // Replace the received URI with the URI that includes the index page
    request.uri = newuri;

    return callback(null, request);
};

In your cloudfront behaviors, you'll edit them to add a call to that lambda function on "Viewer Request"

In my case I'm using an external maven installation with m2e. I've added my proxy settings to the external maven installation's settings.xml file. These settings haven't been used by m2e even after I've set the external maven installation as default maven installation.

To solve the problem I've configured the global maven settings file within eclipse to be the settings.xml file from my external maven installation.

Now eclipse can download the required artifacts.

Public variable declarations in classes is the easiest way:

On target class:

public class MyFragment extends Fragment {
    public MyCallerFragment caller; // Declare the caller var
...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
           Bundle savedInstanceState) {
        // Do what you want with the vars
        caller.str = "I changed your value!";
        caller.i = 9999;
        ...
        return inflater.inflate(R.layout.my_fragment, container, false);
    }
...
}

On caller class:

public class MyCallerFragment extends Fragment {
    public Integer i; // Declared public var
    public String str; // Declared public var
        ...
            FragmentManager fragmentManager = getParentFragmentManager();
            FragmentTransaction transaction = fragmentManager.beginTransaction();

            myFragment = new MyFragment();
            myFragment.caller = this;
            transaction.replace(R.id.nav_host_fragment, myFragment)
                    .addToBackStack(null).commit();
        ...
}

If you want to use the main activity it is easy too:

On main activity class:

public class MainActivity extends AppCompatActivity {
    public String str; // Declare public var
    public EditText myEditText; // You can declare public elements too.
                                // Taking care that you have it assigned
                                // correctly.
...
}

On called class:

public class MyFragment extends Fragment {
    private MainActivity main; // Declare the activity var
...
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
           Bundle savedInstanceState) {
        // Assign the main activity var
        main = (MainActivity) getActivity();

        // Do what you want with the vars
        main.str = "I changed your value!";
        main.myEditText.setText("Wow I can modify the EditText too!");
        ...
        return inflater.inflate(R.layout.my_fragment, container, false);
    }
...
}

Note: Take care when using events (onClick, onChanged, etc) because you can be on a "fighting" situation where more than one assign a variable. The result will be that the variable sometimes does not will change or will return to the last value magically.

For more combinations use your creativity. :)

To simplify the answare let's look on the following code:

#include "stdafx.h"
#include <iostream>
using namespace std;

class A
{
private:
    int m_id;
    static int count;
public:
    A() {count++; m_id = count;}
    A(int id) { m_id = id; }
    ~A() {cout<< "Destructor A "   <<m_id<<endl; }
};

int A::count = 0;

void f1()
{   
    A* arr = new A[10];
    //delete operate only one constructor, and crash!
    delete arr;
    //delete[] arr;
}

int main()
{
    f1();
    system("PAUSE");
    return 0;
}

The output is: Destructor A 1 and then it's crashing (Expression: _BLOCK_TYPE_IS_VALID(phead- nBlockUse)).

We need to use: delete[] arr; becuse it's delete the whole array and not just one cell!

try to use delete[] arr; the output is: Destructor A 10 Destructor A 9 Destructor A 8 Destructor A 7 Destructor A 6 Destructor A 5 Destructor A 4 Destructor A 3 Destructor A 2 Destructor A 1

The same principle is for an array of pointers:

void f2()
{
    A** arr = new A*[10];
    for(int i = 0; i < 10; i++)
    {
        arr[i] = new A(i);
    }
    for(int i = 0; i < 10; i++)
    {
        delete arr[i];//delete the A object allocations.
    }

    delete[] arr;//delete the array of pointers
}

if we'll use delete arr instead of delete[] arr. it will not delete the whole pointers in the array => memory leak of pointer objects!

For PHP, Java, C++, C, Perl, JavaScript, CSS you can try:

To start it right after installation, I generate a batch file with installutil followed by sc start

It's not ideal, but it works....

Very sort cut and effective solution is below:-

Add the below rule in your tsconfig.json file:-

"noImplicitAny": false

Then restart your project.

If you use JSON properly, you can have nested object without any issue :

var xmlhttp = new XMLHttpRequest();   // new HttpRequest instance 
var theUrl = "/json-handler";
xmlhttp.open("POST", theUrl);
xmlhttp.setRequestHeader("Content-Type", "application/json;charset=UTF-8");
xmlhttp.send(JSON.stringify({ "email": "[email protected]", "response": { "name": "Tester" } }));

Because $newDate is an object of type DateTime, not a string. The documentation is explicit:

Returns new DateTime object formatted according to the specified format.

If you want to convert from a string to DateTime back to string to change the format, call DateTime::format at the end to get a formatted string out of your DateTime.

$newDate = DateTime::createFromFormat("l dS F Y", $dateFromDB);
$newDate = $newDate->format('d/m/Y'); // for example

int i = 0;
bool b = Convert.ToBoolean(i);

I know, that's a 8 years old question, but that can still happen today.

Powershell ca be used for that. An example is shown here. The shortest command for the cmd is:

powershell -command "&{(get-host).ui.rawui.windowsize=@{width=100;height=55};}"

Set your wanted window size to the width and hight vars. However, this short line has two limitations:

• Be sure that the window size is not larger than the predefined buffer sizes. Otherwise there occur an error message.
• Depending on the system, loading and processing of Powershell takes 2...4 seconds. Sometimes this is a long time to wait.

To avoid that, in the command below the buffer size is defined. In addition, the process runs parallel to the other following cmd commands:

start /b powershell -command "&{$w=(get-host).ui.rawui;$w.buffersize=@{width=177;height=999};$w.windowsize=@{width=155;height=55};}"

The width and height values to the buffersize object, here 177 and 999, must be bigger or equal to the window size values.

As an alternative to the other answers, it's possible to do this with a syntax similar to the way you originally intended if you do it via a case statement rather than an if:

session := Session{}
switch {
case Session{} == session:
    fmt.Println("zero")
default:
    fmt.Println("not zero")
}

playground example

In some case, I want only to undo the changes on specific files on the first commit to add them to a second commit and have a cleaner git log.

In this case, what I do is the following:

git checkout HEAD~1 <path_to_file_to_put_in_different_commit>
git add -u
git commit --amend --no-edit
git checkout HEAD@{1} <path_to_file_to_put_in_different_commit>
git commit -m "This is the new commit"

Of course, this works well even in the middle of a rebase -i with an edit option on the commit to split.

There is a free open source tool called Anchore that you can use to scan container images. This command will allow you to list all files in a container image

anchore-cli image content myrepo/app:latest files

https://anchore.com/opensource/

function update() {
  $("#notice_div").html('Loading..'); 
  $.ajax({
    type: 'GET',
    url: 'jbede.php',
    timeout: 2000,
    success: function(data) {
      $("#some_div").html(data);
      $("#notice_div").html(''); 
      window.setTimeout(update, 10000);
    },
    error: function (XMLHttpRequest, textStatus, errorThrown) {
      $("#notice_div").html('Timeout contacting server..');
      window.setTimeout(update, 60000);
    }
});
}
$(document).ready(function() {
    update();
});

This is Better Code

You could use .keypress().

For example, consider the HTML:

<form>
  <fieldset>
    <input id="target" type="text" value="Hello there" />
  </fieldset>
</form>
<div id="other">
  Trigger the handler
</div>

The event handler can be bound to the input field:

$("#target").keypress(function() {
  alert("Handler for .keypress() called.");
});

I totally agree with Andy; all depends on how you want it to work.

Looking at the code (runner/__init__.py), I think you can probably set it in your inventory file :

[whatever]
some-host ansible_sudo_pass='foobar'

There seem to be some provision in ansible.cfg config file too, but not implemented right now (constants.py).

Below works for me if your exe depend on some dll or certain dependency then you need to set directory path. As mention below exePath mean folder where exe placed along with it's references files.

Exe application creating any temporaray file so it will create in folder mention in processBuilder.directory(...)

**

ProcessBuilder processBuilder = new ProcessBuilder(arguments);
processBuilder.redirectOutput(Redirect.PIPE);
processBuilder.directory(new File(exePath));
process = processBuilder.start();
int waitFlag = process.waitFor();// Wait to finish application execution.
if (waitFlag == 0) {
...
 int returnVal = process.exitValue();
} 

**

Winand, Quality was also an issue for me so I did this:

For Each ws In ActiveWorkbook.Worksheets
    If ws.PageSetup.PrintArea <> "" Then
        'Reverse the effects of page zoom on the exported image
        zoom_coef = 100 / ws.Parent.Windows(1).Zoom
        areas = Split(ws.PageSetup.PrintArea, ",")
        areaNo = 0
        For Each a In areas
            Set area = ws.Range(a)
            ' Change xlPrinter to xlScreen to see zooming white space
            area.CopyPicture Appearance:=xlPrinter, Format:=xlPicture
            Set chartobj = ws.ChartObjects.Add(0, 0, area.Width * zoom_coef, area.Height * zoom_coef)
            chartobj.Chart.Paste
            'scale the image before export
            ws.Shapes(chartobj.Index).ScaleHeight 3, msoFalse, msoScaleFromTopLeft
            ws.Shapes(chartobj.Index).ScaleWidth 3, msoFalse, msoScaleFromTopLeft
            chartobj.Chart.Export ws.Name & "-" & areaNo & ".png", "png"
            chartobj.delete
            areaNo = areaNo + 1
        Next
    End If
Next

If anyone wonders how to quickly query catalog tables and make use of the pg_get_functiondef() function here's the sample query:

SELECT n.nspname AS schema
      ,proname AS fname
      ,proargnames AS args
      ,t.typname AS return_type
      ,d.description
      ,pg_get_functiondef(p.oid) as definition
--      ,CASE WHEN NOT p.proisagg THEN pg_get_functiondef(p.oid)
--            ELSE 'pg_get_functiondef() can''t be used with aggregate functions'
--       END as definition
  FROM pg_proc p
  JOIN pg_type t
    ON p.prorettype = t.oid
  LEFT OUTER
  JOIN pg_description d
    ON p.oid = d.objoid
  LEFT OUTER
  JOIN pg_namespace n
    ON n.oid = p.pronamespace
 WHERE NOT p.proisagg
   AND n.nspname~'<$SCHEMA_NAME_PATTERN>'
   AND proname~'<$FUNCTION_NAME_PATTERN>'

To answer your question, firstly I would strongly recommend looking at the Documentation.

Without overriding the equals() method, it will act like "==". When you use the "==" operator on objects, it simply checks to see if those pointers refer to the same object. Not if their members contain the same value.

We override to keep our code clean, and abstract the comparison logic from the If statement, into the object. This is considered good practice and takes advantage of Java's heavily Object Oriented Approach.

for(var key in validation_messages){
    for(var subkey in validation_messages[key]){
        //code here
        //subkey being value, key being 'yourname' / 'yourmsg'
    }
}

If every input asks the same question, you should use a for loop and an array of inputs:

Scanner dd = new Scanner(System.in);
int[] vars = new int[3];

for(int i = 0; i < vars.length; i++) {
  System.out.println("Enter next var: ");
  vars[i] = dd.nextInt();
}

Or as Chip suggested, you can parse the input from one line:

Scanner in = new Scanner(System.in);
int[] vars = new int[3];

System.out.println("Enter "+vars.length+" vars: ");
for(int i = 0; i < vars.length; i++)
  vars[i] = in.nextInt();

You were on the right track, and what you did works. This is just a nicer and more flexible way of doing things.

Let's take this:

class Person(val name:String,var age:Int )
def person =new Person("Kumar",12)
person.age=20
println(person.age)

and rewrite it with equivalent code

class Person(val name:String,var age:Int )
def person =new Person("Kumar",12)
(new Person("Kumar", 12)).age_=(20)
println((new Person("Kumar", 12)).age)

See, def is a method. It will execute each time it is called, and each time it will return (a) new Person("Kumar", 12). And these is no error in the "assignment" because it isn't really an assignment, but just a call to the age_= method (provided by var).

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean
Dim time2 As Date
Dim time1 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.
        '(Only one row in your example. This can be adjusted if needed.)
        For Each x In Range("B2:E2") 'Change these to match your real ranges.
            'Check to see if our dep time corresponds to
            'the matching column in our output
            If t.Column = x.Column Then
                'If it does, then check to see what our time value is
                If x > 0 Then
                    time2 = x.Value
                    'Apply the change to the output cell.
                    t.Value = time1 - time2
                    'Exit out of this loop and move to the next output cell.
                    Exit For
                End If
            End If
            'If the columns don't match, or the x value is not a time
            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E

Because you are talking about your replacement being anything, and also replacing in the middle of an element's children, it becomes more tricky than just inserting a singular element, or directly removing and appending:

function replaceTargetWith( targetID, html ){
  /// find our target
  var i, tmp, elm, last, target = document.getElementById(targetID);
  /// create a temporary div or tr (to support tds)
  tmp = document.createElement(html.indexOf('<td')!=-1?'tr':'div'));
  /// fill that div with our html, this generates our children
  tmp.innerHTML = html;
  /// step through the temporary div's children and insertBefore our target
  i = tmp.childNodes.length;
  /// the insertBefore method was more complicated than I first thought so I 
  /// have improved it. Have to be careful when dealing with child lists as  
  /// they are counted as live lists and so will update as and when you make
  /// changes. This is why it is best to work backwards when moving children 
  /// around, and why I'm assigning the elements I'm working with to `elm` 
  /// and `last`
  last = target;
  while(i--){
    target.parentNode.insertBefore((elm = tmp.childNodes[i]), last);
    last = elm;
  }
  /// remove the target.
  target.parentNode.removeChild(target);
}

example usage:

replaceTargetWith( 'idTABLE', 'I <b>can</b> be <div>anything</div>' );

demo:

• http://jsfiddle.net/97H5Y/1/

By using the .innerHTML of our temporary div this will generate the TextNodes and Elements we need to insert without any hard work. But rather than insert the temporary div itself -- this would give us mark up that we don't want -- we can just scan and insert it's children.

...either that or look to using jQuery and it's replaceWith method.

jQuery('#idTABLE').replaceWith('<blink>Why this tag??</blink>');

update 2012/11/15

As a response to EL 2002's comment above:

It not always possible. For example, when createElement('div') and set its innerHTML as <td>123</td>, this div becomes <div>123</div> (js throws away inappropriate td tag)

The above problem obviously negates my solution as well - I have updated my code above accordingly (at least for the td issue). However for certain HTML this will occur no matter what you do. All user agents interpret HTML via their own parsing rules, but nearly all of them will attempt to auto-correct bad HTML. The only way to achieve exactly what you are talking about (in some of your examples) is to take the HTML out of the DOM entirely, and manipulate it as a string. This will be the only way to achieve a markup string with the following (jQuery will not get around this issue either):

<table><tr>123 text<td>END</td></tr></table>

If you then take this string an inject it into the DOM, depending on the browser you will get the following:

123 text<table><tr><td>END</td></tr></table>

<table><tr><td>END</td></tr></table>

The only question that remains is why you would want to achieve broken HTML in the first place? :)

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

Not exactly for this OP, but for those who encountered 404 and cannot set response content-type to "application/json" (any content-type). One possibility is a server actually responds 406 but explorer (e.g., chrome) prints it as 404.

If you do not customize message converter, spring would use AbstractMessageConverterMethodProcessor.java. It would run:

List<MediaType> requestedMediaTypes = getAcceptableMediaTypes(request);
List<MediaType> producibleMediaTypes = getProducibleMediaTypes(request, valueType, declaredType);

and if they do not have any overlapping (the same item), it would throw HttpMediaTypeNotAcceptableException and this finally causes 406. No matter if it is an ajax, or GET/POST, or form action, if the request uri ends with a .html or any suffix, the requestedMediaTypes would be "text/[that suffix]", and this conflicts with producibleMediaTypes, which is usually:

"application/json"  
"application/xml"   
"text/xml"          
"application/*+xml" 
"application/json"  
"application/*+json"
"application/json"  
"application/*+json"
"application/xml"   
"text/xml"          
"application/*+xml"
"application/xml"  
"text/xml"

Here is how you can read the entire file contents, and if done successfully, start a webserver which displays the JPG image in response to every request:

var http = require('http')
var fs = require('fs')

fs.readFile('image.jpg', function(err, data) {
  if (err) throw err // Fail if the file can't be read.
  http.createServer(function(req, res) {
    res.writeHead(200, {'Content-Type': 'image/jpeg'})
    res.end(data) // Send the file data to the browser.
  }).listen(8124)
  console.log('Server running at http://localhost:8124/')
})

Note that the server is launched by the "readFile" callback function and the response header has Content-Type: image/jpeg.

[Edit] You could even embed the image in an HTML page directly by using an <img> with a data URI source. For example:

  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body><img src="data:image/jpeg;base64,')
  res.write(Buffer.from(data).toString('base64'));
  res.end('"/></body></html>');

I want to complete the answer from tchester.

(1) Enable the xp_cmdshell procedure:

-- To allow advanced options to be changed.
EXEC sp_configure 'show advanced options', 1
RECONFIGURE
GO

-- Enable the xp_cmdshell procedure
EXEC sp_configure 'xp_cmdshell', 1
RECONFIGURE
GO

(2) Create a login 'Domain\TestUser' (windows user) for the non-sysadmin user that has public access to the master database

(3) Grant EXEC permission on the xp_cmdshell stored procedure:

GRANT EXECUTE ON xp_cmdshell TO [Domain\TestUser]

(4) Create a proxy account that xp_cmdshell will be run under using sp_xp_cmdshell_proxy_account

EXEC sp_xp_cmdshell_proxy_account 'Domain\TestUser', 'pwd'
-- Note: pwd means windows password for [Domain\TestUser] account id on the box.
--       Don't include square brackets around Domain\TestUser.

(5) Grant control server permission to user

USE master;
GRANT CONTROL SERVER TO [Domain\TestUser]
GO

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

You should use setStroke to set a stroke of the Graphics2D object.

The example at http://www.java2s.com gives you some code examples.

The following code produces the image below:

import java.awt.*;
import java.awt.geom.Line2D;
import javax.swing.*;

public class FrameTest {
    public static void main(String[] args) {
        JFrame jf = new JFrame("Demo");
        Container cp = jf.getContentPane();
        cp.add(new JComponent() {
            public void paintComponent(Graphics g) {
                Graphics2D g2 = (Graphics2D) g;
                g2.setStroke(new BasicStroke(10));
                g2.draw(new Line2D.Float(30, 20, 80, 90));
            }
        });
        jf.setSize(300, 200);
        jf.setVisible(true);
    }
}

(Note that the setStroke method is not available in the Graphics object. You have to cast it to a Graphics2D object.)

If you use Spring frameworks, then you can use CollectionUtils to check against both Collections (List, Array) and Map etc.

if(CollectionUtils.isEmpty(...)) {...}

NOTE - See Edit 4 if 3 digit precision is important

var discount = (price / listprice).toFixed(2);

toFixed will round up or down for you depending on the values beyond 2 decimals.

Example: http://jsfiddle.net/calder12/tv9HY/

Documentation: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number/toFixed

Edit - As mentioned by others this converts the result to a string. To avoid this:

var discount = +((price / listprice).toFixed(2));

Edit 2- As also mentioned in the comments this function fails in some precision, in the case of 1.005 for example it will return 1.00 instead of 1.01. If accuracy to this degree is important I've found this answer: https://stackoverflow.com/a/32605063/1726511 Which seems to work well with all the tests I've tried.

There is one minor modification required though, the function in the answer linked above returns whole numbers when it rounds to one, so for example 99.004 will return 99 instead of 99.00 which isn't ideal for displaying prices.

Edit 3 - Seems having the toFixed on the actual return was STILL screwing up some numbers, this final edit appears to work. Geez so many reworks!

var discount = roundTo((price / listprice), 2);

function roundTo(n, digits) {
  if (digits === undefined) {
    digits = 0;
  }

  var multiplicator = Math.pow(10, digits);
  n = parseFloat((n * multiplicator).toFixed(11));
  var test =(Math.round(n) / multiplicator);
  return +(test.toFixed(digits));
}

See Fiddle example here: https://jsfiddle.net/calder12/3Lbhfy5s/

Edit 4 - You guys are killing me. Edit 3 fails on negative numbers, without digging into why it's just easier to deal with turning a negative number positive before doing the rounding, then turning it back before returning the result.

function roundTo(n, digits) {
    var negative = false;
    if (digits === undefined) {
        digits = 0;
    }
    if (n < 0) {
        negative = true;
        n = n * -1;
    }
    var multiplicator = Math.pow(10, digits);
    n = parseFloat((n * multiplicator).toFixed(11));
    n = (Math.round(n) / multiplicator).toFixed(digits);
    if (negative) {
        n = (n * -1).toFixed(digits);
    }
    return n;
}

Fiddle: https://jsfiddle.net/3Lbhfy5s/79/

Here you go:

function encodeQueryData(data) {
   const ret = [];
   for (let d in data)
     ret.push(encodeURIComponent(d) + '=' + encodeURIComponent(data[d]));
   return ret.join('&');
}

Usage:

const data = { 'first name': 'George', 'last name': 'Jetson', 'age': 110 };
const querystring = encodeQueryData(data);

$(document).ready(function() {
  $('#div_one').bind('click', function() {
    $('#div_two').addClass('large');
  });
});

If I understood your question.

Or you can modify css directly:

var $speech = $('div.speech');
var currentSize = $speech.css('fontSize');
$speech.css('fontSize', '10px');

cv2 uses numpy for manipulating images, so the proper and best way to get the size of an image is using numpy.shape. Assuming you are working with BGR images, here is an example:

>>> import numpy as np
>>> import cv2
>>> img = cv2.imread('foo.jpg')
>>> height, width, channels = img.shape
>>> print height, width, channels
  600 800 3

In case you were working with binary images, img will have two dimensions, and therefore you must change the code to: height, width = img.shape

I finally found out how to do this! Basically you need to run adb shell first and then while you're in the shell run su, which will switch the shell to run as root!

$: adb shell
$: su

The one problem I still have is that sqlite3 is not installed so the command is not recognized.

If I understand your issue this should work

&emsp—the em space; this should be a very wide space, typically as much as four real spaces. &ensp—the en space; this should be a somewhat wide space, roughly two regular spaces. &thinsp—this will be a narrow space, even more narrow than a regular space.

Simple Solution :)

const ID = (_length=13) => {
  // Math.random to base 36 (numbers, letters),
  // grab the first 9 characters
  // after the decimal.
  return '_' + Math.random().toString(36).substr(2, _length); // max _length should be less then 13
};
console.log("Example ID()::", ID())

Have you considered simply using Local/Session Storage? -or- Depending on the complexity of what you're building; you could even use indexDB.

note:

Local storage and indexDB are not secure - so you want to avoid storing any sensitive / personal data (i.e names, addresses, emails addresses, DOB etc) in either of these.

Session Storage is a more secure option for anything sensitive, it's only accessible to the origin that set the items and also clears as soon as the browser / tab is closed.

IndexDB is a little more [but not much more] complicated and is a 30MB noSQL database built into every browser (but can be basically unlimited if the user opts in) -> next time you're using Google docs, open you DevTools -> application -> IndexDB and take a peak. [spoiler alert: it's encrypted].

Focusing on Local and Session Storage; these are both dead simple to use:

// To Set 
sessionStorage.setItem( 'key' , 'value' );

// e.g.
sessionStorage.setItem( 'formData' , { name: "Mr Manager", company: "Bluth's Frozen Bananas", ...  } );    

// Get The Data 
const fromData = sessionStorage.getItem( 'key' );     

// e.g. (after navigating to next location)
const fromData = sessionStorage.getItem( 'formData' );

// Remove 
sessionStorage.removeItem( 'key' );

// Remove _all_ saved data sessionStorage
sessionStorage.clear( ); 

If simple is not your thing -or- maybe you want to go off road and try a different approach all together -> you can probably use a shared web worker... y'know, just for kicks.

To show leading zeros infront of hours, minutes and seconds use below modified code. The trick here is we are converting (or more accurately formatting) integer into string so that it shows leading zero whenever applicable :

public String convertTimeWithTimeZome(long time) {
        Calendar cal = Calendar.getInstance();
        cal.setTimeZone(TimeZone.getTimeZone("UTC"));
        cal.setTimeInMillis(time);
        String curTime = String.format("%02d:%02d:%02d", cal.get(Calendar.HOUR_OF_DAY), cal.get(Calendar.MINUTE), cal.get(Calendar.SECOND));
        return curTime;
    }

Result would be like : 00:01:30

Like @Khashaa and @Richard Scriven point out in comments, you have to set consistent column names for all the data frames you want to append.

Hence, you need to explicitly declare the columns names for the second data frame, de, then use rbind(). You only set column names for the first data frame, df:

df<-data.frame("hi","bye")
names(df)<-c("hello","goodbye")

de<-data.frame("hola","ciao")
names(de)<-c("hello","goodbye")

newdf <- rbind(df, de)

In my case I had an ambiguous reference in my code. I restarted Visual Studio and was able to see the error message. When I resolved this the other error disappeared.

One thing you can do is, you might have subfolders for each projects. So, install mongoose in that subfolders and require() mongoose from own folders in each sub applications. Not from the project root or from global. So one sub project, one mongoose installation and one mongoose instance.

-app_root/
--foo_app/
---db_access.js
---foo_db_connect.js
---node_modules/
----mongoose/
--bar_app/
---db_access.js
---bar_db_connect.js
---node_modules/
----mongoose/

In foo_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/foo_db');
module.exports = exports = mongoose;

In bar_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/bar_db');
module.exports = exports = mongoose;

In db_access.js files

var mongoose = require("./foo_db_connect.js"); // bar_db_connect.js for bar app

Now, you can access multiple databases with mongoose.

CREATE PROCEDURE dbo.pdpd_DynamicCall 
AS
DECLARE @SQLString_2 NVARCHAR(4000)
SET NOCOUNT ON
Begin
    --- Create global temp table
    CREATE TABLE ##T1 ( column_1 varchar(10) , column_2 varchar(100) )

    SELECT @SQLString_2 = 'INSERT INTO ##T1( column_1, column_2) SELECT column_1 = "123", column_2 = "MUHAMMAD IMRON"'
    SELECT @SQLString_2 = REPLACE(@SQLString_2, '"', '''')

    EXEC SP_EXECUTESQL @SQLString_2

    --- Test Display records
    SELECT * FROM ##T1

    --- Drop global temp table 
    IF OBJECT_ID('tempdb..##T1','u') IS NOT NULL
    DROP TABLE ##T1
End

Quote from Android Docs:

If you need to format your strings using String.format(String, Object...), then you can do so by putting your format arguments in the string resource. For example, with the following resource:

<string name="welcome_messages">Hello, %1$s! You have %2$d new messages.</string>

In this example, the format string has two arguments: %1$s is a string and %2$d is a decimal number. You can format the string with arguments from your application like this:

Resources res = getResources();
String text = String.format(res.getString(R.string.welcome_messages), username, mailCount);

In C or C++ local objects are usually allocated on the stack. You are allocating a large array on the stack, more than the stack can handle, so you are getting a stackoverflow.

Don't allocate it local on stack, use some other place instead. This can be achieved by either making the object global or allocating it on the global heap. Global variables are fine, if you don't use the from any other compilation unit. To make sure this doesn't happen by accident, add a static storage specifier, otherwise just use the heap.

This will allocate in the BSS segment, which is a part of the heap:

static int c[1000000];
int main()
{
   cout << "done\n";
   return 0;
}

This will allocate in the DATA segment, which is a part of the heap too:

int c[1000000] = {};
int main()
{
   cout << "done\n";
   return 0;
}

This will allocate at some unspecified location in the heap:

int main()
{
   int* c = new int[1000000];
   cout << "done\n";
   return 0;
}

I. Plain XSLT 1.0 solution:

This transformation:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()" name="split">
  <xsl:param name="pText" select="."/>
  <xsl:if test="string-length($pText)">
   <xsl:if test="not($pText=.)">
    <br />
   </xsl:if>
   <xsl:value-of select=
    "substring-before(concat($pText,';'),';')"/>
   <xsl:call-template name="split">
    <xsl:with-param name="pText" select=
     "substring-after($pText, ';')"/>
   </xsl:call-template>
  </xsl:if>
 </xsl:template>
</xsl:stylesheet>

when applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

produces the wanted, corrected result:

123 Elm Street<br />PO Box 222<br />c/o James Jones

II. FXSL 1 (for XSLT 1.0):

Here we just use the FXSL template str-map (and do not have to write recursive template for the 999th time):

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:f="http://fxsl.sf.net/"
xmlns:testmap="testmap"
exclude-result-prefixes="xsl f testmap"
>
   <xsl:import href="str-dvc-map.xsl"/>

   <testmap:testmap/>

   <xsl:output omit-xml-declaration="yes" indent="yes"/>

   <xsl:template match="/">
     <xsl:variable name="vTestMap" select="document('')/*/testmap:*[1]"/>
     <xsl:call-template name="str-map">
       <xsl:with-param name="pFun" select="$vTestMap"/>
       <xsl:with-param name="pStr" select=
       "'123 Elm Street;PO Box 222;c/o James Jones'"/>
     </xsl:call-template>
   </xsl:template>

    <xsl:template name="replace" mode="f:FXSL"
         match="*[namespace-uri() = 'testmap']">
      <xsl:param name="arg1"/>

      <xsl:choose>
       <xsl:when test="not($arg1=';')">
        <xsl:value-of select="$arg1"/>
       </xsl:when>
       <xsl:otherwise><br /></xsl:otherwise>
      </xsl:choose>
    </xsl:template>
</xsl:stylesheet>

when this transformation is applied on any XML document (not used), the same, wanted correct result is produced:

123 Elm Street<br/>PO Box 222<br/>c/o James Jones

III. Using XSLT 2.0

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="text()">
  <xsl:for-each select="tokenize(.,';')">
   <xsl:sequence select="."/>
   <xsl:if test="not(position() eq last())"><br /></xsl:if>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

when this transformation is applied on this XML document:

<t>123 Elm Street;PO Box 222;c/o James Jones</t>

the wanted, correct result is produced:

123 Elm Street<br />PO Box 222<br />c/o James Jones

$@ is same as $*, but each parameter is a quoted string, that is, the parameters are passed on intact, without interpretation or expansion. This means, among other things, that each parameter in the argument list is seen as a separate word.

Of course, "$@" should be quoted.

http://tldp.org/LDP/abs/html/internalvariables.html#ARGLIST

Here is another idea that allow you to affect other elements without considering any specific selector and by only using the :hover state of the main element.

For this, I will rely on the use of custom properties (CSS variables). As we can read in the specification:

Custom properties are ordinary properties, so they can be declared on any element, are resolved with the normal inheritance and cascade rules ...

The idea is to define custom properties within the main element and use them to style child elements and since these properties are inherited we simply need to change them within the main element on hover.

Here is an example:

#container {_x000D_
  width: 200px;_x000D_
  height: 30px;_x000D_
  border: 1px solid var(--c);_x000D_
  --c:red;_x000D_
}_x000D_
#container:hover {_x000D_
  --c:blue;_x000D_
}_x000D_
#container > div {_x000D_
  width: 30px;_x000D_
  height: 100%;_x000D_
  background-color: var(--c);_x000D_
}

<div id="container">_x000D_
  <div>_x000D_
  </div>_x000D_
</div>

Why this can be better than using specific selector combined with hover?

I can provide at least 2 reasons that make this method a good one to consider:

1. If we have many nested elements that share the same styles, this will avoid us complex selector to target all of them on hover. Using Custom properties, we simply change the value when hovering on the parent element.
2. A custom property can be used to replace a value of any property and also a partial value of it. For example we can define a custom property for a color and we use it within a border, linear-gradient, background-color, box-shadow etc. This will avoid us reseting all these properties on hover.

Here is a more complex example:

.container {_x000D_
  --c:red;_x000D_
  width:400px;_x000D_
  display:flex;_x000D_
  border:1px solid var(--c);_x000D_
  justify-content:space-between;_x000D_
  padding:5px;_x000D_
  background:linear-gradient(var(--c),var(--c)) 0 50%/100% 3px no-repeat;_x000D_
}_x000D_
.box {_x000D_
  width:30%;_x000D_
  background:var(--c);_x000D_
  box-shadow:0px 0px 5px var(--c);_x000D_
  position:relative;_x000D_
}_x000D_
.box:before {_x000D_
  content:"A";_x000D_
  display:block;_x000D_
  width:15px;_x000D_
  margin:0 auto;_x000D_
  height:100%;_x000D_
  color:var(--c);_x000D_
  background:#fff;_x000D_
}_x000D_
_x000D_
/*Hover*/_x000D_
.container:hover {_x000D_
  --c:blue;_x000D_
}

<div class="container">_x000D_
<div class="box"></div>_x000D_
<div class="box"></div>_x000D_
</div>

As we can see above, we only need one CSS declaration in order to change many properties of different elements.

SELECT Q.FK
      ,ISNULL(T1.Field1, T2.Field2) AS Field
FROM (SELECT FK FROM Table1
        UNION
      SELECT FK FROM Table2) AS Q
LEFT JOIN Table1 AS T1 ON T1.FK = Q.FK
LEFT JOIN Table2 AS T2 ON T2.FK = Q.FK

If there is one table, write Table1 instead of Table2

Use the setAttribute method:

document.getElementById('item1').setAttribute('data', "icon: 'base2.gif', url: 'output.htm', target: 'AccessPage', output: '1'");

But you really should be using data followed with a dash and with its property, like:

<li ... data-icon="base.gif" ...>

And to do it in JS use the dataset property:

document.getElementById('item1').dataset.icon = "base.gif";

Let's say you have this code:

public void method() {
        CompletableFuture.runAsync(() -> {
            //logic
            //logic
            //logic
            //logic
        });
    }

Try to refactor it to something like this:

public void refactoredMethod() {
    CompletableFuture.runAsync(this::subMethod);
}

private void subMethod() {
    //logic
    //logic
    //logic
    //logic
}

After that, test the subMethod this way:

org.powermock.reflect.Whitebox.invokeMethod(classInstance, "subMethod"); 

This isn't a perfect solution, but it tests all the logic inside your async execution.

yourEnumList.Select(s => (int)s).ToList()

The answer might very well depend on the compiler, so you probably want to edit your question (I mean, even the notion of segments is not mandated by ISO C nor ISO C++). For instance, on Windows an executable doesn't carry symbol names. One 'foo' would be offset 0x100, the other perhaps 0x2B0, and code from both translation units is compiled knowing the offsets for "their" foo.

A simple, but not pure java solution, is to shell out to curl from java, which gives you complete control over how the request is done. If you're just doing this for something simple, this allows you to ignore certificate errors at times, by using this method. This example shows how to make a request against a secure server with a valid or invalid certificate, pass in a cookie, and get the output using curl from java.

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;

public class MyTestClass
{
  public static void main(String[] args) 
  {
    String url = "https://www.google.com";
    String sessionId = "faf419e0-45a5-47b3-96d1-8c62b2a3b558";

    // Curl options are:
    // -k: ignore certificate errors
    // -L: follow redirects
    // -s: non verbose
    // -H: add a http header

    String[] command = { "curl", "-k", "-L", "-s", "-H", "Cookie: MYSESSIONCOOKIENAME=" + sessionId + ";", "-H", "Accept:*/*", url };
    String output = executeShellCmd(command, "/tmp", true, true);
    System.out.println(output);
  }

  public String executeShellCmd(String[] command, String workingFolder, boolean wantsOutput, boolean wantsErrors)
  {
    try
    {
      ProcessBuilder pb = new ProcessBuilder(command);
      File wf = new File(workingFolder);
      pb.directory(wf);

      Process proc = pb.start();
      BufferedReader stdInput = new BufferedReader(new InputStreamReader(proc.getInputStream()));
      BufferedReader stdError = new BufferedReader(new InputStreamReader(proc.getErrorStream()));

      StringBuffer sb = new StringBuffer();
      String newLine = System.getProperty("line.separator");
      String s;

      // read stdout from the command
      if (wantsOutput)
      {
        while ((s = stdInput.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      // read any errors from the attempted command
      if (wantsErrors)
      {
        while ((s = stdError.readLine()) != null)
        {
          sb.append(s);
          sb.append(newLine);
        }
      }

      String result = sb.toString();

      return result;

DATEPART function doesn't work on MySQL 5.6, instead use MONTH('2018-01-01')

Take a backup of your htdocs and data folder (subfolder of MySQL folder), reinstall upgraded version and replace those folders.

Note: In case you have changed config files like PHP (php.ini), Apache (httpd.conf) or any other, please take back up of those files as well and replace them with newly installed version.

Clear answers are already provided. But it's worth mentioning how devDependencies affects installing packages:

By default, npm install will install all modules listed as dependencies in package.json . With the --production flag (or when the NODE_ENV environment variable is set to production ), npm will not install modules listed in devDependencies .

See: https://docs.npmjs.com/cli/install

I get this error because a field was varbinary in sqlserver table instead of varchar.

You are trying to insert data that is larger than allowed for the column logo.

Use following data types as per your need

TINYBLOB   :     maximum length of 255 bytes  
BLOB       :     maximum length of 65,535 bytes  
MEDIUMBLOB :     maximum length of 16,777,215 bytes  
LONGBLOB   :     maximum length of 4,294,967,295 bytes  

Use LONGBLOB to avoid this exception.

I think the first answer is the best I wrote my own shell script developing this idea :

#!/bin/sh
if [ $# -ne 1 ]
then
    echo "Sintaxis:\n\t"
    echo " $0 {port to search in process }"
    exit
else
    MYPORT=$1
    for i in `ls /proc`
    do

       pfiles $i | grep port | grep "port: $MYPORT" > /dev/null
       if [ $? -eq 0 ]
         then
           echo " Port $MYPORT founded in $i proccess !!!\n\n"
           echo "Details\n\t"
           pfiles $i | grep port | grep "port: $MYPORT"
           echo "\n\t"
           echo "Process detail: \n\t"
           ps -ef | grep $i  | grep -v grep
       fi
    done
fi

For Mac users who want to check whether your processor supports virtualisation, use the maccpuid software and look for VMX. If it is checked then you're good to go.

To extract number :

var arrNumber = new Array();
$('input[type=number]').each(function(){
    arrNumber.push($(this).val());
})

To extract text:

var arrText= new Array();
$('input[type=text]').each(function(){
    arrText.push($(this).val());
})

Edit : .map implementation

var arrText= $('input[type=text]').map(function(){
    return this.value;
}).get();

With array_intersect_key and array_flip:

var_dump(array_intersect_key($my_array, array_flip($allowed)));

array(1) {
  ["foo"]=>
  int(1)
}

There is no need of doing such hectic stuffs. Find in your system where there is "SDK Manager".(incase of windows). Suppose your sdk manager is in E:\Android-9. Go to that path double click the SDK manager ;it will automatically start to download from https://dl-ssl.google.com/../..

Initially you will se it is failing. On the window that appears there will be 'settings' menu. Click on that set the proxy and port. and it will start downloading.

The solution in one sentence is "Don't use eclipse for the download;directly use Android sdk manager and your problem is resolved". Let me know if you have any futhur queries on this issue.
