Long shot but try setting the proxy to "" (empty string) that should override any proxy settings according to the man page.

Chances are you need to install .NET 4 (Which will also create a new AppPool for you)

First make sure you have IIS installed then perform the following steps:

1. Open your command prompt (Windows + R) and type cmd and press ENTER
   ^{You may need to start this as an administrator if you have UAC enabled.
   To do so, locate the exe (usually you can start typing with Start Menu open), right click and select "Run as Administrator"}
2. Type cd C:\Windows\Microsoft.NET\Framework\v4.0.30319\ and press ENTER.
3. Type aspnet_regiis.exe -ir and press ENTER again.
   • If this is a fresh version of IIS (no other sites running on it) or you're not worried about the hosted sites breaking with a framework change you can use -i instead of -ir. This will change their AppPools for you and steps 5-on shouldn't be necessary.
   • at this point you will see it begin working on installing .NET's framework in to IIS for you
4. Close the DOS prompt, re-open your start menu and right click Computer and select Manage
5. Expand the left-hand side (Services and Applications) and select Internet Information Services
   • You'll now have a new applet within the content window exclusively for IIS.
6. Expand out your computer and locate the Application Pools node, and select it. (You should now see ASP.NET v4.0 listed)
7. Expand out your Sites node and locate the site you want to modify (select it)
8. To the right you'll notice Basic Settings... just below the Edit Site text. Click this, and a new window should appear
9. Select the .NET 4 AppPool using the Select... button and click ok.
10. Restart the site, and you should be good-to-go.

(You can repeat steps 7-on for every site you want to apply .NET 4 on as well).

3. aspnet_regiis.exe options
   For those that might want to know what -ir or -i does (or the difference between them) or what other options are available. (I typically use -ir to prevent any older sites currently running from breaking on a framework change but that's up to you.)

Below is a positive lookbehind JavaScript alternative showing how to capture the last name of people with 'Michael' as their first name.

1) Given this text:

const exampleText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";

get an array of last names of people named Michael. The result should be: ["Jordan","Johnson","Green","Wood"]

2) Solution:

function getMichaelLastName2(text) {
  return text
    .match(/(?:Michael )([A-Z][a-z]+)/g)
    .map(person => person.slice(person.indexOf(' ')+1));
}

// or even
    .map(person => person.slice(8)); // since we know the length of "Michael "

3) Check solution

console.log(JSON.stringify(    getMichaelLastName(exampleText)    ));
// ["Jordan","Johnson","Green","Wood"]

Demo here: http://codepen.io/PiotrBerebecki/pen/GjwRoo

You can also try it out by running the snippet below.

const inputText = "Michael, how are you? - Cool, how is John Williamns and Michael Jordan? I don't know but Michael Johnson is fine. Michael do you still score points with LeBron James, Michael Green Miller and Michael Wood?";_x000D_
_x000D_
_x000D_
_x000D_
function getMichaelLastName(text) {_x000D_
  return text_x000D_
    .match(/(?:Michael )([A-Z][a-z]+)/g)_x000D_
    .map(person => person.slice(8));_x000D_
}_x000D_
_x000D_
console.log(JSON.stringify(    getMichaelLastName(inputText)    ));

I'd add that in case of really odd behavior - where you spend a couple of hours saying WTF - try manually deleting the /webapps/yourwebapp/WEB-INF/classes directory. A java source file that was moved to another package will not have its compiled class file deleted - at least in the case of an exploded web-application on TC. This can seriously drive you crazy with unpredictable behavior, especially with an annotated servlet.

Aspect-oriented programming lets you trap assignments or fetches and attach intercepting logic to them, which I propose is the right way to solve the problem. (The issue of whether they should be public or protected or package-protected is orthogonal.)

Thus you start out with unintercepted fields with the right access qualifier. As your program requirements grow you attach logic to perhaps validate, make a copy of the object being returned, etc.

The getter/setter philosophy imposes costs on a large number of simple cases where they are not needed.

Whether aspect-style is cleaner or not is somewhat qualitative. I would find it easy to see just the variables in a class and view the logic separately. In fact, the raison d'etre for Apect-oriented programming is that many concerns are cross-cutting and compartmentalizing them in the class body itself is not ideal (logging being an example -- if you want to log all gets Java wants you to write a whole bunch of getters and keeping them in sync but AspectJ allows you a one-liner).

The issue of IDE is a red-herring. It is not so much the typing as it is the reading and visual pollution that arises from get/sets.

Annotations seem similar to aspect-oriented programming at first sight however they require you to exhaustively enumerate pointcuts by attaching annotations, as opposed to a concise wild-card-like pointcut specification in AspectJ.

I hope awareness of AspectJ prevents people from prematurely settling on dynamic languages.

I don't know specifically for redis, but for servers in general:

What OS or distribution? Often there will be a stop or /etc/init.d/... command that will be able to look up the existing pid in a pid file.

You can look up what process is already bound to the port with sudo netstat -nlpt (linux options; other netstat flavors will vary) and signal it to stop. I would not use kill -9 on a running server unless there really is no other signal or method to shut it down.

You shouldn't really do this but insert in a new record instead and update it that way.
But, if you really need to, you can do the following:

• Disable enforcing FK constraints temporarily (e.g. ALTER TABLE foo WITH NOCHECK CONSTRAINT ALL)
• Then update your PK
• Then update your FKs to match the PK change
• Finally enable back enforcing FK constraints

If you use any undefined function in the script then script will stop due to "Uncaught ReferenceError". I have tried by following code and first two lines executed.

I think, this is the best way to stop the script. If there's any other way then please comment me. I also want to know another best and simple way. BTW, I didn't get exit or die inbuilt function in Javascript like PHP for terminate the script. If anyone know then please let me know.

alert('Hello');

document.write('Hello User!!!');

die();  //Uncaught ReferenceError: die is not defined

alert('bye');

document.write('Bye User!!!');

Short answer

1. Reattach without ejecting others: screen -x
2. Get list of displays: ^A *, select the one to disconnect, press d

Explained answer

Background: When I was looking for the solution with same problem description, I have always landed on this answer. I would like to provide more sensible solution. (For example: the other attached screen has a different size and a I cannot force resize it in my terminal.)

Note: PREFIX is usually ^A = ctrl+a

Note: the display may also be called:

• "user front-end" (in at command manual in screen)
• "client" (tmux vocabulary where this functionality is detach-client)
• "terminal" (as we call the window in our user interface) /depending on

1. Reattach a session: screen -x

-x attach to a not detached screen session without detaching it

2. List displays of this session: PREFIX *

It is the default key binding for: PREFIX :displays. Performing it within the screen, identify the other display we want to disconnect (e.g. smaller size). (Your current display is displayed in brighter color/bold when not selected).

term-type   size         user interface           window       Perms
---------- ------- ---------- ----------------- ----------     -----
 screen     240x60         you@/dev/pts/2      nb  0(zsh)        rwx
 screen      78x40         you@/dev/pts/0      nb  0(zsh)        rwx

Using arrows ? ?, select the targeted display, press d If nothing happens, you tried to detach your own display and screen will not detach it. If it was another one, within a second or two, the entry will disappear.

Press ENTER to quit the listing.

Optionally: in order to make the content fit your screen, reflow: PREFIX F (uppercase F)

Excerpt from man page of screen:

displays

Shows a tabular listing of all currently connected user front-ends (displays). This is most useful for multiuser sessions. The following keys can be used in displays list:

• mouseclick Move to the selected line. Available when "mousetrack" is set to on.
• space Refresh the list
• d Detach that display
• D Power detach that display
• C-g, enter, or escape Exit the list

You were close... after your code of

WindowState = FormWindowState.Maximized;

THEN, set the form's min/max size capacity to the value once its sized out.

MinimumSize = this.Size;
MaximumSize = this.Size;

You can view this dump from the UNIX console.

The path for the heap dump will be provided as a variable right after where you have placed the mentioned variable.

E.g.:

-XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=${DOMAIN_HOME}/logs/mps"

You can view the dump from the console on the mentioned path.

This is the basic delegate code you need:

#define kAccelerationThreshold      2.2

#pragma mark -
#pragma mark UIAccelerometerDelegate Methods
    - (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration 
    {   
        if (fabsf(acceleration.x) > kAccelerationThreshold || fabsf(acceleration.y) > kAccelerationThreshold || fabsf(acceleration.z) > kAccelerationThreshold) 
            [self myShakeMethodGoesHere];   
    }

Also set the in the appropriate code in the Interface. i.e:

@interface MyViewController : UIViewController <UIPickerViewDelegate, UIPickerViewDataSource, UIAccelerometerDelegate>

Use df.count() to get the number of rows.

I have been waiting to see if Google would open a Keep API. When I discovered Google Tasks, and saw that it had an Android app, web app, and API, I converted over to Tasks. This may not directly answer your question, but it is my solution to the Keep API problem.

Tasks doesn't have a reminder alarm exactly like Keep. I can live without that if I also connect with the Calendar API.

https://developers.google.com/google-apps/tasks/

I'm not sure I understand your intent perfectly, but perhaps the following would be close to what you want:

select n1.name, n1.author_id, count_1, total_count
  from (select id, name, author_id, count(1) as count_1
          from names
          group by id, name, author_id) n1
inner join (select id, author_id, count(1) as total_count
              from names
              group by id, author_id) n2
  on (n2.id = n1.id and n2.author_id = n1.author_id)

Unfortunately this adds the requirement of grouping the first subquery by id as well as name and author_id, which I don't think was wanted. I'm not sure how to work around that, though, as you need to have id available to join in the second subquery. Perhaps someone else will come up with a better solution.

Share and enjoy.

I have just wrestled with this for 3 hours. I credit the answer from Dherik (Bonus material about AMQP) for bringing me within striking distance of MY answer, YMMV.

I registered the JavaTimeModule in my object mapper in my SpringBootApplication like this:

@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
    ObjectMapper objectMapper = builder.build();
    objectMapper.registerModule(new JavaTimeModule());
    return objectMapper;
}

However my Instants that were coming over the STOMP connection were still not deserialising. Then I realised I had inadvertantly created a MappingJackson2MessageConverter which creates a second ObjectMapper. So I guess the moral of the story is: Are you sure you have adjusted all your ObjectMappers? In my case I replaced the MappingJackson2MessageConverter.objectMapper with the outer version that has the JavaTimeModule registered, and all is well:

@Autowired
ObjectMapper objectMapper;

@Bean
public WebSocketStompClient webSocketStompClient(WebSocketClient webSocketClient,
        StompSessionHandler stompSessionHandler) {
    WebSocketStompClient webSocketStompClient = new WebSocketStompClient(webSocketClient);
    MappingJackson2MessageConverter converter = new MappingJackson2MessageConverter();
    converter.setObjectMapper(objectMapper);
    webSocketStompClient.setMessageConverter(converter);
    webSocketStompClient.connect("http://localhost:8080/myapp", stompSessionHandler);
    return webSocketStompClient;
}

I am not sure whether v13 support library was available when this question was posted, but in case someone is still struggling, I have seen that adding android-support-v13.jar will fix everything. This is how I did it:

1. Right click on the project -> Properties
2. Select Java Build Path from from the left hand side table of content
3. Go to Libraries tab
4. Add External jars button and select <your sdk path>\extras\android\support\v13\android-support-v13.jar

The setup:

    List<int[]> intArrays=new ArrayList<>();
    int anExample[]={1,2,3};
    intArrays.add(anExample);

To retrieve a single int[] array in the ArrayList by index:

    int[] anIntArray = intArrays.get(0); //'0' is the index
    //iterate the retrieved array an print the individual elements
    for (int aNumber : anIntArray ) { 
        System.out.println("Arraylist contains:" + aNumber );
    }

To retrieve all int[] arrays in the ArrayList:

    //iterate the ArrayList, get and print the elements of each int[] array  
    for(int[] anIntArray:intArrays) {
       //iterate the retrieved array an print the individual elements
       for (int aNumber : anIntArray) {
           System.out.println("Arraylist contains:" + aNumber);
       }
}

Output formatting can be performed based on this logic. Goodluck!!

You can pass any command-line argument without additional plugins using --env since webpack 2:

webpack --config webpack.config.js --env.foo=bar

Using the variable in webpack.config.js:

module.exports = function(env) {
    if (env.foo === 'bar') {
        // do something
    }
}

Apache, as usual, has a good answer from Apache Commons-Lang in the form of NumberUtils.isCreatable(String).

Handles nulls, no try/catch block required.

Regex was not meant to validate number ranges(this number must be from 1 to 5 when the number preceding it happens to be a 2 and the number preceding that happens to be below 6). Just look for the pattern of placement of numbers in regex. If you need to validate is qualities of a date, put it in a date object js/c#/vb, and interogate the numbers there.

I had a problem slimier to yours I this quick and its the best solution I have found so far.

Html:

    <div class="center">
      <ul class="dots">
        <span>
          <li></li>
          <li></li>

Not everything here is needed to center the list items.

You can cut the css down to this to get the same effect:

    ul li{display: inline-block;}
    .center{width: 100%;}
    .dots{

@Emil's answer above is brilliant.

Small addition: We should ideally use TelephonyManager to detect network types. So the above should instead read:

/**
 * Check if there is fast connectivity
 * @param context
 * @return
 */
public static boolean isConnectedFast(Context context){
    ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo info = cm.getActiveNetworkInfo();
    TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
    return (info != null && info.isConnected() && Connectivity.isConnectionFast(info.getType(), tm.getNetworkType()));
}

Node : http://www.w3schools.com/js/js_htmldom_nodes.asp

The Node object represents a single node in the document tree. A node can be an element node, an attribute node, a text node, or any other of the node types explained in the Node Types chapter.

Element : http://www.w3schools.com/js/js_htmldom_elements.asp

The Element object represents an element in an XML document. Elements may contain attributes, other elements, or text. If an element contains text, the text is represented in a text-node.

You can use Guava's Streams.concat(Stream<? extends T>... streams) method, which will be very short with static imports:

Stream stream = concat(stream1, stream2, of(element));

You can use these to factor out code common to all tests in the test suite.

If you have a lot of repeated code in your tests, you can make them shorter by moving this code to setUp/tearDown.

You might use this for creating test data (e.g. setting up fakes/mocks), or stubbing out functions with fakes.

If you're doing integration testing, you can use check environmental pre-conditions in setUp, and skip the test if something isn't set up properly.

For example:

class TurretTest(unittest.TestCase):

    def setUp(self):
        self.turret_factory = TurretFactory()
        self.turret = self.turret_factory.CreateTurret()

    def test_turret_is_on_by_default(self):
        self.assertEquals(True, self.turret.is_on())

    def test_turret_turns_can_be_turned_off(self):
        self.turret.turn_off()
        self.assertEquals(False, self.turret.is_on())

You want a capture group.

p = re.compile("name (.*) is valid", re.flags) # parentheses for capture groups
print p.match(s).groups() # This gives you a tuple of your matches.

Dynamic linking is the only practical way to meet some license requirements such as the LGPL.

git fetch origin

If you want to be able to include 0 as a valid value:

if (!!val || val === 0) { ... }

.then function of promiseB receives what is returned from .then function of promiseA.

        g2.drawImage(img, 45, 35, this);
        g2.finalize();

OR use this code

    Image image;
    ImageObserver imageObserver;


    MyButtonl(String filename) {
            super();
            ImageIcon icon = new ImageIcon(filename);
            image = icon.getImage();
            imageObserver = icon.getImageObserver();
        }

     public void paint( Graphics g ) {
            super.paint( g );
            g.drawImage(image,  0 , 0 , getWidth() , getHeight() , imageObserver);
        }
    }

Check out Math.Round. You can then cast the result to an int.

It's a pandas data-frame and it's using label base selection tool with df.loc and in it, there are two inputs, one for the row and the other one for the column, so in the row input it's selecting all those row values where the value saved in the column class is versicolor, and in the column input it's selecting the column with label class, and assigning Iris-versicolor value to them. So basically it's replacing all the cells of column class with value versicolor with Iris-versicolor.

Directly install one of the fink packages (Django 1.6 as of 2013-Nov)

fink install django-py27
fink install django-py33

Or create yourself a virtualenv:

fink install virtualenv-py27
virtualenv django-env
source django-env/bin/activate
pip install django
deactivate # when you are done

Or use fink django plus any other pip installed packages in a virtualenv

fink install django-py27
fink install virtualenv-py27
virtualenv django-env --system-site-packages
source django-env/bin/activate
# django already installed
pip install django-analytical # or anything else you might want
deactivate # back to your normally scheduled programming

The whole thing to em is, that the size is relative to the base. So I would say you could keep the font sizes by altering the base.

Example: If you base is 16px, and p is .75em (which is 12px) you would have to raise the base to about 20px. In this case p would then equal about 15px which is the minimum I personally require for mobile phones.

You need to register the directory with Oracle. fopen takes the name of a directory object, not the path. For example:

(you may need to login as SYS to execute these)

CREATE DIRECTORY MY_DIR AS 'C:\';

GRANT READ ON DIRECTORY MY_DIR TO SCOTT;

Then, you can refer to it in the call to fopen:

execute sal_status('MY_DIR','vin1.txt');

Mysql has this handy UPDATE INTO command ;)

edit Looks like they renamed it to REPLACE

REPLACE works exactly like INSERT, except that if an old row in the table has the same value as a new row for a PRIMARY KEY or a UNIQUE index, the old row is deleted before the new row is inserted

For the datatype Double to int, you can use the following:

Double double = 5.00;

int integer = double.intValue();

You need to either qualify vector with its namespace (which is std), or import the namespace at the top of your CPP file:

using namespace std;

class tile_tree_apple should be defined in a separate .h file.

tta.h:
#include "tile.h"

class tile_tree_apple : public tile
{
      public:
          tile onDestroy() {return *new tile_grass;};
          tile tick() {if (rand()%20==0) return *new tile_tree;};
          void onCreate() {health=rand()%5+4; type=TILET_TREE_APPLE;}; 
          tile onUse() {return *new tile_tree;};       
};

file tt.h
#include "tile.h"

class tile_tree : public tile
{
      public:
          tile onDestroy() {return *new tile_grass;};
          tile tick() {if (rand()%20==0) return *new tile_tree_apple;};
          void onCreate() {health=rand()%5+4; type=TILET_TREE;};        
};

another thing: returning a tile and not a tile reference is not a good idea, unless a tile is a primitive or very "small" type.

IMHO, fs.readFile() should be avoided because it loads ALL the file in memory and it won't call the callback until all the file has been read.

The easiest way to read a text file is to read it line by line. I recommend a BufferedReader:

new BufferedReader ("file", { encoding: "utf8" })
    .on ("error", function (error){
        console.log ("error: " + error);
    })
    .on ("line", function (line){
        console.log ("line: " + line);
    })
    .on ("end", function (){
        console.log ("EOF");
    })
    .read ();

For complex data structures like .properties or json files you need to use a parser (internally it should also use a buffered reader).

'Command + M' for OSX is working for me.

You just need to display the div with id #menu as flex container like this:

#menu{
    width: 800px;
    display: flex;
    justify-content: space-between;
}

Since the original post wanted the pair:

import random
d = {'VENEZUELA':'CARACAS', 'CANADA':'TORONTO'}
country, capital = random.choice(list(d.items()))

Günter Zöchbauer's answer is the right one. Just consider adding the following line:

showImageBrowseDlg() {
    // from http://stackoverflow.com/a/32010791/217408
    let event = new MouseEvent('click', {bubbles: true});
    event.stopPropagation();
    this.renderer.invokeElementMethod(
        this.fileInput.nativeElement, 'dispatchEvent', [event]);
  }

In my case I would get a "caught RangeError: Maximum call stack size exceeded" error if not. (I have a div card firing on click and the input file inside)

Try using the ToDictionary method like so:

var dict = TableObj.ToDictionary( t => t.Key, t => t.TimeStamp );

    sum := int64(0)
    for scanner.Scan() {
        v, err := strconv.ParseInt(scanner.Text(), 10, 64)
        if err != nil {
            fmt.Fprintf(os.Stderr, "Not an integer: '%s'\n", scanner.Text())
            os.Exit(1)
        }
        sum += v
    }
    fmt.Println(sum)
}

            .Include(j => j.Library.Select(k => k.Library.Select(l=>l.Book)))

ax.set_title('My Title\n', fontsize="15", color="red")
plt.imshow(myfile, origin="upper")

If you put '\n' right after your title string, the plot is drawn just below the title. That might be a fast solution too.

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

For preventing the dots in the middle of a word or after a punctuation symbol.

          if(text.charAt(i) === ' ' && (text.charAt(i-1) != ','||text.charAt(i-1) != '.'||text.charAt(i-1) != ';')) {_x000D_

if you want to hide a whole div from the view in another screen size. You can follow bellow code as an example.

div.disabled{
  display: none;
}

I think the simplest way to use the newest version of Node.js is to get the newest Node.js pkg file in the website https://nodejs.org/en/download/current/ if you want to use different version of Node.js you can use nvm or n to manage it.

This worked for me.

git remote update --prune

Use Html.fromHtml

HTML Tags are

<a href=”…”> <b>,  <big>, <blockquote>, <br>, <cite>, <dfn>
<div align=”…”>,  <em>, <font size=”…” color=”…” face=”…”>
<h1>,  <h2>, <h3>, <h4>,  <h5>, <h6>
<i>, <p>, <small>
<strike>,  <strong>, <sub>, <sup>, <tt>, <u>

As per Android’s official Documentations any tags in the HTML will display as a generic replacement String which your program can then go through and replace with real strings.

Html.formHtml method takes an Html.TagHandler and an Html.ImageGetter as arguments as well as the text to parse.

Example

String Str_Html=" <p>This is about me text that the user can put into their profile</p> ";

Then

Your_TextView_Obj.setText(Html.fromHtml(Str_Html).toString());

Output

This is about me text that the user can put into their profile

DECLARE @ADate Date, @ATime Time, @ADateTime Datetime

SELECT @ADate = '2010-02-20', @ATime = '18:53:00.0000000'

SET @ADateTime = CAST   (
    CONVERT(Varchar(10), @ADate, 112) + ' ' +   
    CONVERT(Varchar(8), @ATime) AS DateTime)

SELECT @ADateTime [A nice datetime :)]

This will render you a valid result.

Exactly as arrays in all C-like languages. The indexes start from 0. So, apple is 0, banana is 1, orange is 2 etc.

If you are using jQuery, there is a redirect plugin that works with the POST or GET method. It creates a form with hidden inputs and submits it for you. An example of how to get it working:

$.redirect('demo.php', {'arg1': 'value1', 'arg2': 'value2'});

Note: You can pass the method types GET or POST as an optional third parameter; POST is the default.

Is using System.Threading.Timer mandatory?

If not, System.Timers.Timer has handy Start() and Stop() methods (and an AutoReset property you can set to false, so that the Stop() is not needed and you simply call Start() after executing).

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

You need to set the binding context of the ToolStripComboBox.ComboBox.

Here is a slightly modified version of the code that I have just recreated using Visual Studio. The menu item combo box is called toolStripComboBox1 in my case. Note the last line of code to set the binding context.

I noticed that if the combo is in the visible are of the toolstrip, the binding works without this but not when it is in a drop-down. Do you get the same problem?

If you can't get this working, drop me a line via my contact page and I will send you the project. You won't be able to load it using SharpDevelop but will with C# Express.

var languages = new string[2];
languages[0] = "English";
languages[1] = "German";

DataSet myDataSet = new DataSet();

// --- Preparation
DataTable lTable = new DataTable("Lang");
DataColumn lName = new DataColumn("Language", typeof(string));
lTable.Columns.Add(lName);

for (int i = 0; i < languages.Length; i++)
{
    DataRow lLang = lTable.NewRow();
    lLang["Language"] = languages[i];
    lTable.Rows.Add(lLang);
}
myDataSet.Tables.Add(lTable);

toolStripComboBox1.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView;
toolStripComboBox1.ComboBox.DisplayMember = "Language";

If you run pub build --mode=debug the build directory contains the application without symlinks. The Dart code should be retained when --mode=debug is used.

Here is some discussion going on about this topic too Dart and it's place in Rails Assets Pipeline

A thread is an execution context, which is all the information a CPU needs to execute a stream of instructions.

Suppose you're reading a book, and you want to take a break right now, but you want to be able to come back and resume reading from the exact point where you stopped. One way to achieve that is by jotting down the page number, line number, and word number. So your execution context for reading a book is these 3 numbers.

If you have a roommate, and she's using the same technique, she can take the book while you're not using it, and resume reading from where she stopped. Then you can take it back, and resume it from where you were.

Threads work in the same way. A CPU is giving you the illusion that it's doing multiple computations at the same time. It does that by spending a bit of time on each computation. It can do that because it has an execution context for each computation. Just like you can share a book with your friend, many tasks can share a CPU.

On a more technical level, an execution context (therefore a thread) consists of the values of the CPU's registers.

Last: threads are different from processes. A thread is a context of execution, while a process is a bunch of resources associated with a computation. A process can have one or many threads.

Clarification: the resources associated with a process include memory pages (all the threads in a process have the same view of the memory), file descriptors (e.g., open sockets), and security credentials (e.g., the ID of the user who started the process).

This article shows how to do it real easy.

1. To rename a local Git branch, we can use the Git branch -m command to modify the name:

    git branch -m feature1 feature2
   

2. If you’re just looking for the command to rename a remote Git branch, this is it:

    git push -u origin feature2:feature3
   

   Check that you have no tags on the branch before you do this. You can do that with git tag.

Complementing the @djechlin answer (good answer by the way!), this function call could be also used as dummy code to hold a breakpoint in an IDE when you want to stop in some specific iteration or a particular recursive call, for example:

isUserAGoat() could be used instead of a dummy variable declaration that will be shown in the IDE as a warning and, in Eclipse particular case, will clog the breakpoint mark, making it difficult to enable/disable it. If the method is used as a convention, all the invocations could be later filtered by some script (during commit phase maybe?).

Google guys are heavy Eclipse users (they provide several of their projects as Eclipse plugins: Android SDK, GAE, etc), so the @djechlin answer and this complementary answer make a lot of sense (at least for me).

A backreference to the whole match value is \g<0>, see re.sub documentation:

The backreference \g<0> substitutes in the entire substring matched by the RE.

See the Python demo:

import re
method = 'images/:id/huge'
print(re.sub(r':[a-z]+', r'<span>\g<0></span>', method))
# => images/<span>:id</span>/huge

Inline elements:

1. respect left & right margins and padding, but not top & bottom
2. cannot have a width and height set
3. allow other elements to sit to their left and right.
4. see very important side notes on this here.

Block elements:

1. respect all of those
2. force a line break after the block element
3. acquires full-width if width not defined

Inline-block elements:

1. allow other elements to sit to their left and right
2. respect top & bottom margins and padding
3. respect height and width

From W3Schools:

• An inline element has no line break before or after it, and it tolerates HTML elements next to it.

• A block element has some whitespace above and below it and does not tolerate any HTML elements next to it.

• An inline-block element is placed as an inline element (on the same line as adjacent content), but it behaves as a block element.

When you visualize this, it looks like this:

The image is taken from this page, which also talks some more about this subject.

Note one can also get this error if you do this;

while read line; do
  echo $line
done << somefile

Because << somefile should read < somefile in this case.

Perhaps:

> data.frame(aname=NA, bname=NA)[numeric(0), ]
[1] aname bname
<0 rows> (or 0-length row.names)

You can do it with dynamic_cast (at least for polymorphic types).

Actually, on second thought--you can't tell if it is SPECIFICALLY a particular type with dynamic_cast--but you can tell if it is that type or any subclass thereof.

template <class DstType, class SrcType>
bool IsType(const SrcType* src)
{
  return dynamic_cast<const DstType*>(src) != nullptr;
}

I presume you mean curve-fitting and not anti-aliasing from the context of your question. PyPlot doesn't have any built-in support for this, but you can easily implement some basic curve-fitting yourself, like the code seen here, or if you're using GuiQwt it has a curve fitting module. (You could probably also steal the code from SciPy to do this as well).

You can do it in a number of ways.

IF EXISTS(select * from ....)
begin
 -- select * from .... 
end
else
 -- do something 

Or you can use IF NOT EXISTS , @@ROW_COUNT like

select * from ....
IF(@@ROW_COUNT>0)
begin
-- do something
end

Try https://checkstyle.sourceforge.io/config_filters.html#SuppressionXpathFilter

You can configure it as:

<module name="SuppressionXpathFilter">
  <property name="file" value="suppressions-xpath.xml"/>

The suppressions-xpath.xml is specified as the Xpath suppressions source in the Checkstyle rules configuration. In the snippet above, I'm loading the Checkstyle classpath from a file cs.cp into a property. You can choose to specify the classpath directly.

Or you could use groovy within Maven (or Ant) to do the same:

import java.nio.file.Files
import java.nio.file.StandardCopyOption  
import java.nio.file.Paths

def backupSuppressions() {
  def supprFileName = 
      project.properties["checkstyle.suppressionsFile"]
  def suppr = Paths.get(supprFileName)
  def target = null
  if (Files.exists(suppr)) {
    def supprBak = Paths.get(supprFileName + ".bak")
    target = Files.move(suppr, supprBak,
        StandardCopyOption.REPLACE_EXISTING)
    println "Backed up " + supprFileName
  }
  return target
}

def renameSuppressions() {
  def supprFileName = 
      project.properties["checkstyle.suppressionsFile"]
  def suppr = Paths.get(project.name + "-xpath.xml")
  def target = null
  if (Files.exists(suppr)) {
    def supprNew = Paths.get(supprFileName)
    target = Files.move(suppr, supprNew)
    println "Renamed " + suppr + " to " + supprFileName
  }
  return target
}

def getClassPath(classLoader, sb) {
  classLoader.getURLs().each {url->
     sb.append("${url.getFile().toString()}:")
  }

  }
  return sb.toString()
}

String[] args = ["java", "-cp", cp,
    csMainClass,

ProcessBuilder pb = new ProcessBuilder(args)

The only drawback with using Xpath suppressions---besides the checks it doesn't support---is if you have code like the following:

package cstests;

public interface TestMagicNumber {
  static byte[] getAsciiRotator() {
    byte[] rotation = new byte[95 * 2];
    for (byte i = ' '; i <= '~'; i++) {
      rotation[i - ' '] = i;
      rotation[i + 95 - ' '] = i;
    }
    return rotation;
  }
}

The Xpath suppression generated in this case is not ingested by Checkstyle and the checker fails with an exception on the generated suppression:

<suppress-xpath
       files="TestMagicNumber.java"
       checks="MagicNumberCheck"
       query="/INTERFACE_DEF[./IDENT[@text='TestMagicNumber']]/OBJBLOCK/METHOD_DEF[./IDENT[@text='getAsciiRotator']]/SLIST/LITERAL_FOR/SLIST/EXPR/ASSIGN[./IDENT[@text='i']]/INDEX_OP[./IDENT[@text='rotation']]/EXPR/MINUS[./CHAR_LITERAL[@text='' '']]/PLUS[./IDENT[@text='i']]/NUM_INT[@text='95']"/>

Generating Xpath suppressions is recommended when you have fixed all other violations and wish to suppress the rest. It will not allow you to select specific instances in the code to suppress. You can , however, pick and choose suppressions from the generated file to do just that.

SuppressionXpathSingleFilter is better suited to identify and suppress a specific rule, file or error message. You can configure multiple filters identifying each one by the id attribute.

    }
}

Here's an example that uses the class:

try {
    // Generate a temporary key. In practice, you would save this key.
    // See also Encrypting with DES Using a Pass Phrase.
    SecretKey key = KeyGenerator.getInstance("DES").generateKey();

    // Create encrypter/decrypter class
    DesEncrypter encrypter = new DesEncrypter(key);

    // Encrypt
    String encrypted = encrypter.encrypt("Don't tell anybody!");

    // Decrypt
    String decrypted = encrypter.decrypt(encrypted);
} catch (Exception e) {
}

HTML with font-awesome glyphicon.

<span class="fa fa-spinner spin"></span>

@-moz-keyframes spin {
    to { -moz-transform: rotate(360deg); }
}
@-webkit-keyframes spin {
    to { -webkit-transform: rotate(360deg); }
}
@keyframes spin {
    to {transform:rotate(360deg);}
}

.spin {
    animation: spin 1000ms linear infinite;
}

Currently there is no better way, however there may be a marginal improvement by moving SaveChanges inside for loop for probably 10 items.

int i = 0;

foreach (Employees item in sequence)
{
   t = new Employees ();
   t.Text = item.Text;
   dataContext.Employees.AddObject(t);   

   // this will add max 10 items together
   if((i % 10) == 0){
       dataContext.SaveChanges();
       // show some progress to user based on
       // value of i
   }
   i++;
}
dataContext.SaveChanges();

You can adjust 10 to be closer to better performance. It will not greatly improve speed but it will allow you to show some progress to user and make it more user friendly.

You can use the following

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));

When i checked i saw display: none; value is in the .dropdown-menu bootstrap css class. Hence i removed it.

$query = $this->db->get('mytable', 10, 20);

// get_where sample, 
$query = $this->db->get_where('mytable', array('id' => $id), 10, 20);

// Produces: LIMIT 10
$this->db->limit(10);  

// Produces: LIMIT 10 OFFSET 20

$this->db->limit(10, 20);

It seems strange, but nonetheless HTML5 supports drawing lines, circles, rectangles and many other basic shapes, it does not have anything suitable for drawing the basic point. The only way to do so is to simulate a point with whatever you have.

So basically there are 3 possible solutions:

• draw point as a line
• draw point as a polygon
• draw point as a circle

Each of them has their drawbacks.

Line

function point(x, y, canvas){
  canvas.beginPath();
  canvas.moveTo(x, y);
  canvas.lineTo(x+1, y+1);
  canvas.stroke();
}

Keep in mind that we are drawing to South-East direction, and if this is the edge, there can be a problem. But you can also draw in any other direction.

Rectangle

function point(x, y, canvas){
  canvas.strokeRect(x,y,1,1);
}

or in a faster way using fillRect because render engine will just fill one pixel.

function point(x, y, canvas){
  canvas.fillRect(x,y,1,1);
}

Circle

One of the problems with circles is that it is harder for an engine to render them

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.stroke();
}

the same idea as with rectangle you can achieve with fill.

function point(x, y, canvas){
  canvas.beginPath();
  canvas.arc(x, y, 1, 0, 2 * Math.PI, true);
  canvas.fill();
}

Problems with all these solutions:

• it is hard to keep track of all the points you are going to draw.
• when you zoom in, it looks ugly

If you are wondering, what is the best way to draw a point, I would go with filled rectangle. You can see my jsperf here with comparison tests

Another pure BASH way:

> s='/some/random/file.csv:some string'
> echo "${s%%:*}"
/some/random/file.csv

From my perspective it is more semantic to use <hr> elements as line breaks between flex items.

.container {_x000D_
  display: flex;_x000D_
  flex-flow: wrap;_x000D_
}_x000D_
_x000D_
.container hr {_x000D_
  width: 100%;_x000D_
}

<div class="container">_x000D_
  <div>1</div>_x000D_
  <div>2</div>_x000D_
  <hr>_x000D_
  <div>3</div>_x000D_
  <div>2</div>_x000D_
  ..._x000D_
</div>

Tested in Chrome 66, Firefox 60 and Safari 11.

Simple edit for 2020:

This worked for me. Change the chart to global by making it window owned (Change the declaration from var myChart to window myChart)

Check whether the chart variable is already initialized as Chart, if so, destroy it and create a new one, even you can create another one on the same name. Below is the code:

if(window.myChart instanceof Chart)
{
    window.myChart.destroy();
}
var ctx = document.getElementById('myChart').getContext("2d");

Hope it works!

Correction to top query above, to allow to run from any database

SELECT COUNT(COLUMN_NAME) FROM [*database*].INFORMATION_SCHEMA.COLUMNS WHERE 
TABLE_CATALOG = 'database' AND TABLE_SCHEMA = 'dbo'
AND TABLE_NAME = 'table'

if the table does not have primary key or unique non-nullable defined, then MySql workbench could not able to edit the data.

This won't work, yet void * can help a lot in defining generic pointer to functions and passing it as an argument to another function (similar to callback in Java) or define it a structure similar to oop.

Based on @Rick answer which was really helpful.

You have to scape the string data if you want to share it this way:

$('a.download').attr('href', 'data:application/csv;charset=utf-8,'+ encodeURI(data));

` Sorry I can not comment on @Rick's answer due to my current low reputation in StackOverflow.

An edit suggestion was shared and rejected.

I've been able to input values within the character ":

db_user="postgresql"
db_passwd="this,is,my,password"

Accepted answer is correct , extending it to use 2 or more character in substring:

Declare @string varchar(1000)
Set @string = 'aa,bb,cc,dd'
Set @substring = 'aa'
select (len(@string) - len(replace(@string, @substring, '')))/len(@substring)

I noticed that Visual Studio's built-in error detector kind of gets goofy if you try to do this:

var intvar = @(ViewBag.someNumericValue);

Because @(ViewBag.someNumericValue) has the potential to evaluate to nothing, which would lead to the following erroneous JavaScript being generated:

var intvar = ;

If you're certain that someNemericValue will be set to a valid numeric data type, you can avoid having Visual Studio warnings by doing the following:

var intvar = Number(@(ViewBag.someNumericValue));

This might generate the following sample:

var intvar = Number(25.4);

And it works for negative numbers. In the event that the item isn't in your viewbag, Number() evaluates to 0.

No more Visual Studio warnings! But make sure the value is set and is numeric, otherwise you're opening doors to possible JavaScript injection attacks or run time errors.

A classic "or" would be |. For example, ab|de would match either side of the expression.

However, for something like your case you might want to use the ? quantifier, which will match the previous expression exactly 0 or 1 times (1 times preferred; i.e. it's a "greedy" match). Another (probably more relyable) alternative would be using a custom character group:

\d+\s+[A-Z\s]+\s+[A-Z][A-Za-z]+

This pattern will match:

• \d+: One or more numbers.
• \s+: One or more whitespaces.
• [A-Z\s]+: One or more uppercase characters or space characters
• \s+: One or more whitespaces.
• [A-Z][A-Za-z\s]+: An uppercase character followed by at least one more character (uppercase or lowercase) or whitespaces.

If you'd like a more static check, e.g. indeed only match ABC and A ABC, then you can combine a (non-matching) group and define the alternatives inside (to limit the scope):

\d (?:ABC|A ABC) Street

Or another alternative using a quantifier:

\d (?:A )?ABC Street

If your string will always be of that format, a regex is overkill:

>>> var g='{getThis}';
>>> g.substring(1,g.length-1)
"getThis"

substring(1 means to start one character in (just past the first {) and ,g.length-1) means to take characters until (but not including) the character at the string length minus one. This works because the position is zero-based, i.e. g.length-1 is the last position.

For readers other than the original poster: If it has to be a regex, use /{([^}]*)}/ if you want to allow empty strings, or /{([^}]+)}/ if you want to only match when there is at least one character between the curly braces. Breakdown:

• /: start the regex pattern
  • {: a literal curly brace
    • (: start capturing
      • [: start defining a class of characters to capture
        • ^}: "anything other than }"
      • ]: OK, that's our whole class definition
      • *: any number of characters matching that class we just defined
    • ): done capturing
  • }: a literal curly brace must immediately follow what we captured
• /: end the regex pattern

As of Swift 3 / 4 / 5, this is done as follows.

To add a new element to the end of an Array.

anArray.append("This String")

To append a different Array to the end of your Array.

anArray += ["Moar", "Strings"]
anArray.append(contentsOf: ["Moar", "Strings"])

To insert a new element into your Array.

anArray.insert("This String", at: 0)

To insert the contents of a different Array into your Array.

anArray.insert(contentsOf: ["Moar", "Strings"], at: 0)

More information can be found in the "Collection Types" chapter of "The Swift Programming Language", starting on page 110.

Also, when you uninstall the package, the first item listed is the directory to the executable.

1.Right click on your java project.

2.Select "RUN AS".

3.Select "RUN CONFIGURATIOS...".

4.Here select your server at left side of the page and then u would see "CLASS PATH" tab at riht side,just click on it.

5.Here clilck on "USER ENTRIES" and select "ADD EXTERNAL JARS".

6.Select "ojdbc14.jar" file.

7.Click on Apply.

8.Click on Run.

9.Finally Restart your server then it would be execute.

If you happen to be doing this on Android, there is a nice utility for this called TextUtils which has a .join(String delimiter, Iterable) method.

List<String> list = new ArrayList<String>();
list.add("Item 1");
list.add("Item 2");
String joined = TextUtils.join(", ", list);

Obviously not much use outside of Android, but figured I'd add it to this thread...

I had a hard time finding where it is so here the image depicting it in 2019.

I dont think you need regex to achieve this. I would look at the SubString method along with the indexOf method. If you need more help, add a comment showing what you have attempted and I will offer more help.

You need to put "here" into a <div> or <span> with style="float: right".

Splat Method with Calculations

If you choose splat method, beware calculations that are made using other parameters. In practice, sometimes I have to set variables first then create the hash table. Also, the format doesn't require single quotes around the key value or the semi-colon (as mentioned above).

Example of a call to a function that creates an Excel spreadsheet

$title = "Cut-off File Processing on $start_date_long_str"
$title_row = 1
$header_row = 2
$data_row_start = 3
$data_row_end = $($data_row_start + $($file_info_array.Count) - 1)

# use parameter hash table to make code more readable
$params = @{
    title = $title
    title_row = $title_row
    header_row = $header_row
    data_row_start = $data_row_start
    data_row_end = $data_row_end
}
$xl_wksht = Create-Excel-Spreadsheet @params

Note: The file array contains information that will affect how the spreadsheet is populated.

Every example here shows a solution using the FileReader. It is convenient if you do not need to care about a file encoding. If you use some other languages than english, encoding is quite important. Imagine you have file with this text

Príliš žlutoucký kun
úpel dábelské ódy

and the file uses windows-1250 format. If you use FileReader you will get this result:

P??li? ?lu?ou?k? k??
?p?l ??belsk? ?dy

So in this case you would need to specify encoding as Cp1250 (Windows Eastern European) but the FileReader doesn't allow you to do so. In this case you should use InputStreamReader on a FileInputStream.

Example:

String encoding = "Cp1250";
File file = new File("foo.txt");

if (file.exists()) {
    try (BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file), encoding))) {
        String line = null;
        while ((line = br.readLine()) != null) {
            System.out.println(line);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
}
else {
    System.out.println("file doesn't exist");
}

In case you want to read the file character after character do not use BufferedReader.

try (InputStreamReader isr = new InputStreamReader(new FileInputStream(file), encoding)) {
    int data = isr.read();
    while (data != -1) {
        System.out.print((char) data);
        data = isr.read();
    }
} catch (IOException e) {
    e.printStackTrace();
}

According to Beau Smith from this subject: How do I remove the blue styling of telephone numbers on iPhone/iOS?

You should apply "tel:" in the href attribute of your link like this:

<a href="tel:5551231234">555 123-1234</a>

It will remove any additionnal style and DOM to the phone number string.

Have you tried the following?:

textbox1.text = System.DateTime.Today.ToString("MM/dd/yy");

Be aware that 2 digit years could be bad in the future...

I was getting a similar issue from the Apache Lounge 32 bit version. After downloading the 64 bit version, the issue was resolved.

Here is an excellent video explain the steps involved: https://www.youtube.com/watch?v=17qhikHv5hY

One thing I've used with good results is the following (I don't know if its mentioned already because I can't remember its name).

You precompute a table T with a random number for each character in your key's alphabet [0,255]. You hash your key 'k0 k1 k2 ... kN' by taking T[k0] xor T[k1] xor ... xor T[kN]. You can easily show that this is as random as your random number generator and its computationally very feasible and if you really run into a very bad instance with lots of collisions you can just repeat the whole thing using a fresh batch of random numbers.

A few things I've noted:

• SurfaceViews contain a nice rendering mechanism that allows threads to update the surface's content without using a handler (good for animation).
• Surfaceviews cannot be transparent, they can only appear behind other elements in the view hierarchy.
• I've found that they are much faster for animation than rendering onto a View.

For more information (and a great usage example) refer to the LunarLander project in the SDK 's examples section.

One other way would be to manually edit the configuration file for your user (e.g. /var/lib/jenkins/users/username/config.xml) and update the contents of passwordHash:

<passwordHash>#jbcrypt:$2a$10$razd3L1aXndFfBNHO95aj.IVrFydsxkcQCcLmujmFQzll3hcUrY7S</passwordHash>

Once you have done this, just restart Jenkins and log in using this password:

test

You can you the distinct keyword in you criteria builder like this.

CriteriaBuilder builder = session.getCriteriaBuilder();
CriteriaQuery<Orders> query = builder.createQuery(Orders.class);
Root<Orders> root = query.from(Orders.class);
query.distinct(true).multiselect(root.get("cust_email").as(String.class));

And create the field constructor in your model class.

Firstly, your project file must be a py file which is direct python file. If your file is in ipynb format, you can convert it to py type by using the line of code below:

jupyter nbconvert --to=python

Then, you need to install pipreqs library from cmd (terminal for mac).

pip install pipreqs

Now we can create txt file by using the code below. If you are in the same path with your file, you can just write ./ . Otherwise you need to give path of your file.

pipreqs ./

or

pipreqs /home/project/location

That will create a requirements.txt file for your project.

The previous answers come close, but to meet the actual requirement that the @ symbol stay close, you'd want that to be str.Replace("@", "@" + System.Environment.NewLine). That will keep the @ symbol and add the appropriate newline character(s) for the current platform.

It also works without jQuery if you do the following changes:

1. Add type="button" to the edit button in order not to trigger submission of the form.

2. Change the name of your function from change() to anything else.

n = int(input())          #n is the number of items you want to enter
d ={}                     
for i in range(n):        
    text = input().split()     #split the input text based on space & store in the list 'text'
    d[text[0]] = text[1]       #assign the 1st item to key and 2nd item to value of the dictionary
print(d)

INPUT:

A1023 CRT

A1029 Regulator

A1030 Therm

NOTE: I have added an extra line for each input for getting each input on individual lines on this site. As placing without an extra line creates a single line.

OUTPUT:

{'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}

I realize I'm quite late to the party, and since language wasn't actually specified, here's a VB.NET solution based on Bimmerbound's answer, in case anyone happens to stumble across this and needs a solution. Note: you need to have a reference to the stringbuilder class in your project, if you don't already.

 Shared Function returnSerializedXML(ByVal obj As Object) As String
    Dim xmlSerializer As New System.Xml.Serialization.XmlSerializer(obj.GetType())
    Dim xmlSb As New StringBuilder
    Using textWriter As New IO.StringWriter(xmlSb)
        xmlSerializer.Serialize(textWriter, obj)
    End Using


    returnSerializedXML = xmlSb.ToString().Replace(vbCrLf, "")

End Function

Simply call the function and it will return a string with the serialized xml of the object you're attempting to pass to the web service (realistically, this should work for any object you care to throw at it too).

As a side note, the replace call in the function before returning the xml is to strip out vbCrLf characters from the output. Mine had a bunch of them within the generated xml however this will obviously vary depending on what you're trying to serialize, and i think they might be stripped out during the object being sent to the web service.

Consider also using SETX - it will set variable on user or machine (available for all users) level though the variable will be usable with the next opening of the cmd.exe ,so often it can be used together with SET :

::setting variable for the current user
if not defined My_Var (
  set "My_Var=My_Value"
  setx My_Var My_Value
)

::setting machine defined variable
if not defined Global_Var (
  set "Global_Var=Global_Value"
  SetX Global_Var Global_Value /m
)

You can also edit directly the registry values:

User Variables: HKEY_CURRENT_USER\Environment

System Variables: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment

Which will allow to avoid some restrictions of SET and SETX like the variables containing = in their names.

All other answer are correct, but remember that if you cast double to int you will loss decimal value.. so 2.9 double become 2 int.

You can use Math.round(double) function or simply do :

(int)(yourDoubleValue + 0.5d)

Solution:

Set the property RetainSameConnection on the Connection Manager to True so that temporary table created in one Control Flow task can be retained in another task.

Here is a sample SSIS package written in SSIS 2008 R2 that illustrates using temporary tables.

Walkthrough:

Create a stored procedure that will create a temporary table named ##tmpStateProvince and populate with few records. The sample SSIS package will first call the stored procedure and then will fetch the temporary table data to populate the records into another database table. The sample package will use the database named Sora Use the below create stored procedure script.

USE Sora;
GO

CREATE PROCEDURE dbo.PopulateTempTable
AS
BEGIN
    
    SET NOCOUNT ON;

    IF OBJECT_ID('TempDB..##tmpStateProvince') IS NOT NULL
        DROP TABLE ##tmpStateProvince;

    CREATE TABLE ##tmpStateProvince
    (
            CountryCode     nvarchar(3)         NOT NULL
        ,   StateCode       nvarchar(3)         NOT NULL
        ,   Name            nvarchar(30)        NOT NULL
    );

    INSERT INTO ##tmpStateProvince 
        (CountryCode, StateCode, Name)
    VALUES
        ('CA', 'AB', 'Alberta'),
        ('US', 'CA', 'California'),
        ('DE', 'HH', 'Hamburg'),
        ('FR', '86', 'Vienne'),
        ('AU', 'SA', 'South Australia'),
        ('VI', 'VI', 'Virgin Islands');
END
GO

Create a table named dbo.StateProvince that will be used as the destination table to populate the records from temporary table. Use the below create table script to create the destination table.

USE Sora;
GO

CREATE TABLE dbo.StateProvince
(
        StateProvinceID int IDENTITY(1,1)   NOT NULL
    ,   CountryCode     nvarchar(3)         NOT NULL
    ,   StateCode       nvarchar(3)         NOT NULL
    ,   Name            nvarchar(30)        NOT NULL
    CONSTRAINT [PK_StateProvinceID] PRIMARY KEY CLUSTERED
        ([StateProvinceID] ASC)
) ON [PRIMARY];
GO

Create an SSIS package using Business Intelligence Development Studio (BIDS). Right-click on the Connection Managers tab at the bottom of the package and click New OLE DB Connection... to create a new connection to access SQL Server 2008 R2 database.

Click New... on Configure OLE DB Connection Manager.

Perform the following actions on the Connection Manager dialog.

• Select Native OLE DB\SQL Server Native Client 10.0 from Provider since the package will connect to SQL Server 2008 R2 database
• Enter the Server name, like MACHINENAME\INSTANCE
• Select Use Windows Authentication from Log on to the server section or whichever you prefer.
• Select the database from Select or enter a database name, the sample uses the database name Sora.
• Click Test Connection
• Click OK on the Test connection succeeded message.
• Click OK on Connection Manager

The newly created data connection will appear on Configure OLE DB Connection Manager. Click OK.

OLE DB connection manager KIWI\SQLSERVER2008R2.Sora will appear under the Connection Manager tab at the bottom of the package. Right-click the connection manager and click Properties

Set the property RetainSameConnection on the connection KIWI\SQLSERVER2008R2.Sora to the value True.

Right-click anywhere inside the package and then click Variables to view the variables pane. Create the following variables.

• A new variable named PopulateTempTable of data type String in the package scope SO_5631010 and set the variable with the value EXEC dbo.PopulateTempTable.

• A new variable named FetchTempData of data type String in the package scope SO_5631010 and set the variable with the value SELECT CountryCode, StateCode, Name FROM ##tmpStateProvince

Drag and drop an Execute SQL Task on to the Control Flow tab. Double-click the Execute SQL Task to view the Execute SQL Task Editor.

On the General page of the Execute SQL Task Editor, perform the following actions.

• Set the Name to Create and populate temp table
• Set the Connection Type to OLE DB
• Set the Connection to KIWI\SQLSERVER2008R2.Sora
• Select Variable from SQLSourceType
• Select User::PopulateTempTable from SourceVariable
• Click OK

Drag and drop a Data Flow Task onto the Control Flow tab. Rename the Data Flow Task as Transfer temp data to database table. Connect the green arrow from the Execute SQL Task to the Data Flow Task.

Double-click the Data Flow Task to switch to Data Flow tab. Drag and drop an OLE DB Source onto the Data Flow tab. Double-click OLE DB Source to view the OLE DB Source Editor.

On the Connection Manager page of the OLE DB Source Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select SQL command from variable from Data access mode
• Select User::FetchTempData from Variable name
• Click Columns page

Clicking Columns page on OLE DB Source Editor will display the following error because the table ##tmpStateProvince specified in the source command variable does not exist and SSIS is unable to read the column definition.

To fix the error, execute the statement EXEC dbo.PopulateTempTable using SQL Server Management Studio (SSMS) on the database Sora so that the stored procedure will create the temporary table. After executing the stored procedure, click Columns page on OLE DB Source Editor, you will see the column information. Click OK.

Drag and drop OLE DB Destination onto the Data Flow tab. Connect the green arrow from OLE DB Source to OLE DB Destination. Double-click OLE DB Destination to open OLE DB Destination Editor.

On the Connection Manager page of the OLE DB Destination Editor, perform the following actions.

• Select KIWI\SQLSERVER2008R2.Sora from OLE DB Connection Manager
• Select Table or view - fast load from Data access mode
• Select [dbo].[StateProvince] from Name of the table or the view
• Click Mappings page

Click Mappings page on the OLE DB Destination Editor would automatically map the columns if the input and output column names are same. Click OK. Column StateProvinceID does not have a matching input column and it is defined as an IDENTITY column in database. Hence, no mapping is required.

Data Flow tab should look something like this after configuring all the components.

Click the OLE DB Source on Data Flow tab and press F4 to view Properties. Set the property ValidateExternalMetadata to False so that SSIS would not try to check for the existence of the temporary table during validation phase of the package execution.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the number of rows in the table. It should be empty before executing the package.

Execute the package. Control Flow shows successful execution.

In Data Flow tab, you will notice that the package successfully processed 6 rows. The stored procedure created early in this posted inserted 6 rows into the temporary table.

Execute the query select * from dbo.StateProvince in the SQL Server Management Studio (SSMS) to find the 6 rows successfully inserted into the table. The data should match with rows founds in the stored procedure.

The above example illustrated how to create and use temporary table within a package.

You can try export http_proxy=http://your_proxy:your_port

Your controller method should be like this:

@RequestMapping(value = " /<your mapping>/{id}", method=RequestMethod.GET)
public String listNotes(@PathVariable("id")int id,Model model) {
    Person person = personService.getCurrentlyAuthenticatedUser();
    int id = 2323;  // Currently passing static values for testing
    model.addAttribute("person", new Person());
    model.addAttribute("listPersons", this.personService.listPersons());
    model.addAttribute("listNotes",this.notesService.listNotesBySectionId(id,person));
    return "note";
}

Use the id in your code, call the controller method from your JSP as:

/{your mapping}/{your id}

UPDATE:

Change your jsp code to:

<c:forEach items="${listNotes}" var="notices" varStatus="status">
    <tr>
        <td>${notices.noticesid}</td>
        <td>${notices.notetext}</td>
        <td>${notices.notetag}</td>
        <td>${notices.notecolor}</td>
        <td>${notices.sectionid}</td>
        <td>${notices.canvasid}</td>
        <td>${notices.canvasnName}</td>
        <td>${notices.personid}</td>
        <td><a href="<c:url value='/editnote/${listNotes[status.index].noticesid}' />" >Edit</a></td>
        <td><a href="<c:url value='/removenote/${listNotes[status.index].noticesid}' />" >Delete</a></td>
    </tr>
</c:forEach>

As many people noticed, it's not a date problem, it's a logic problem. Let's assume a day is splitted in two intervals: one lies between 20:11:13 and 14:49:00, while the other lies between 14:49:00 and 20:11:13 (which interval the extremes belong is up to you). If you want to check if a certain time is included in the 20:11:13/14:49:00 one, the one you're interested of, just check if it's included in the other one, 14:49:00/20:11:13, which is much easier because the natural order of the numbers, and then negate the result.

I have a problem with all these solutions.

They're not exactly the same, and they all create files that have a slight size difference compared to the RMB --> send to --> compressed (zipped) folder when made from the same source folder. The closest size-difference I have had is 300 KB difference (script > manual), made with:

powershell Compress-Archive -Path C:\sourceFolder -CompressionLevel Fastest -DestinationPath C:\destinationArchive.zip

(Notice the -CompressionLevel. There are three possible values: Fastest, NoCompression & Optimal, (Default: Optimal))

I wanted to make a .bat file that should automatically compress a WordPress plugin folder I'm working on, into a .zip archive, so I can upload it into the WordPress site and test the plugin.

But for some reason it doesn't work with any of these automatic compressions, but it does work with the manual RMB compression, witch I find really strange.

And the script-generated .zip files actually break the WordPress plugins to the point where they can't be activated, and they can also not be deleted from inside WordPress. I have to SSH into the "back side" of the server and delete the uploaded plugin files themselves, manually. While the manually RMB-generated files work normally.

Just change moveCamera to animateCamera like below

Googlemap.animateCamera(CameraUpdateFactory.newLatLngZoom(locate, 16F))

Python 2.7

In python 2, the keys(), values(), and items() functions of OrderedDict return lists. Using values as an example, the simplest way is

d.values()[0]  # "python"
d.values()[1]  # "spam"

For large collections where you only care about a single index, you can avoid creating the full list using the generator versions, iterkeys, itervalues and iteritems:

import itertools
next(itertools.islice(d.itervalues(), 0, 1))  # "python"
next(itertools.islice(d.itervalues(), 1, 2))  # "spam"

The indexed.py package provides IndexedOrderedDict, which is designed for this use case and will be the fastest option.

from indexed import IndexedOrderedDict
d = IndexedOrderedDict({'foo':'python','bar':'spam'})
d.values()[0]  # "python"
d.values()[1]  # "spam"

Using itervalues can be considerably faster for large dictionaries with random access:

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 1000;   d = OrderedDict({i:i for i in range(size)})'  'i = randint(0, size-1); d.values()[i:i+1]'

$ python2 -m timeit -s 'from collections import OrderedDict; from random import randint; size = 1000;   d = OrderedDict({i:i for i in range(size)})' 'i = randint(0, size-1); next(itertools.islice(d.itervalues(), i, i+1))'

Python 3.6

Python 3 has the same two basic options (list vs generator), but the dict methods return generators by default.

List method:

list(d.values())[0]  # "python"
list(d.values())[1]  # "spam"

Generator method:

import itertools
next(itertools.islice(d.values(), 0, 1))  # "python"
next(itertools.islice(d.values(), 1, 2))  # "spam"

Python 3 dictionaries are an order of magnitude faster than python 2 and have similar speedups for using generators.

+--------+-----------+----------------+---------+
|  size  | list (ms) | generator (ms) | indexed |
+--------+-----------+----------------+---------+
|   1000 | .0316     | .0165          | .00262  |
|  10000 | .288      | .166           | .00294  |
| 100000 | 3.53      | 1.48           | .00332  |
+--------+-----------+----------------+---------+

Use a loop

for(var i = 0; i < obj.length; ++i){
   //do something with obj[i]
   for(var ind in obj[i]) {
        console.log(ind);
        for(var vals in obj[i][ind]){
            console.log(vals, obj[i][ind][vals]);
        }
   }
}

WebAudio API by W3C

As of July 2012, the WebAudio API is now supported in Chrome, and at least partly supported in Firefox, and is slated to be added to IOS as of version 6.

Although it is robust enough to be used programatically for basic tasks, the Audio element was never meant to provide full audio support for games, etc. It was designed to allow a single piece of media to be embedded in a page, similar to an img tag. There are a lot of issues with trying to use the Audio tag for games:

• Timing slips are common with Audio elements
• You need an Audio element for each instance of a sound
• Load events aren't totally reliable, yet
• No common volume controls, no fading, no filters/effects

I used this Getting Started With WebAudio article to get started with the WebAudio API. The FieldRunners WebAudio Case Study is also a good read.

You're very close, the problem is you're comparing a DateTime to a TimeOfDay. What you need to do is add the .TimeOfDay property to the end of your Convert.ToDateTime() functions.

There is the beforeShowDay option, which takes a function to be called for each date, returning true if the date is allowed or false if it is not. From the docs:

beforeShowDay

The function takes a date as a parameter and must return an array with [0] equal to true/false indicating whether or not this date is selectable and 1 equal to a CSS class name(s) or '' for the default presentation. It is called for each day in the datepicker before is it displayed.

Display some national holidays in the datepicker.

$(".selector").datepicker({ beforeShowDay: nationalDays})   

natDays = [
  [1, 26, 'au'], [2, 6, 'nz'], [3, 17, 'ie'],
  [4, 27, 'za'], [5, 25, 'ar'], [6, 6, 'se'],
  [7, 4, 'us'], [8, 17, 'id'], [9, 7, 'br'],
  [10, 1, 'cn'], [11, 22, 'lb'], [12, 12, 'ke']
];

function nationalDays(date) {
    for (i = 0; i < natDays.length; i++) {
      if (date.getMonth() == natDays[i][0] - 1
          && date.getDate() == natDays[i][1]) {
        return [false, natDays[i][2] + '_day'];
      }
    }
  return [true, ''];
}

One built in function exists, called noWeekends, that prevents the selection of weekend days.

$(".selector").datepicker({ beforeShowDay: $.datepicker.noWeekends })

To combine the two, you could do something like (assuming the nationalDays function from above):

$(".selector").datepicker({ beforeShowDay: noWeekendsOrHolidays})   

function noWeekendsOrHolidays(date) {
    var noWeekend = $.datepicker.noWeekends(date);
    if (noWeekend[0]) {
        return nationalDays(date);
    } else {
        return noWeekend;
    }
}

Update: Note that as of jQuery UI 1.8.19, the beforeShowDay option also accepts an optional third paremeter, a popup tooltip

The move instruction copies a value from one register to another. The li instruction loads a specific numeric value into that register.

For the specific case of zero, you can use either the constant zero or the zero register to get that:

move $s0, $zero
li   $s0, 0

There's no register that generates a value other than zero, though, so you'd have to use li if you wanted some other number, like:

li $s0, 12345678

And if you are using typescript (gulpfile.ts) then do this for yargs (building on @Caio Cunha's excellent answer https://stackoverflow.com/a/23038290/1019307 and other comments above):

Install

npm install --save-dev yargs

typings install dt~yargs --global --save

.ts files

Add this to the .ts files:

import { argv } from 'yargs';

...

  let debug: boolean = argv.debug;

This has to be done in each .ts file individually (even the tools/tasks/project files that are imported into the gulpfile.ts/js).

Run

gulp build.dev --debug

Or under npm pass the arg through to gulp:

npm run build.dev -- --debug

Sometimes a BEFORE trigger can be replaced with an AFTER one, but this doesn't appear to be the case in your situation, for you clearly need to provide a value before the insert takes place. So, for that purpose, the closest functionality would seem to be the INSTEAD OF trigger one, as @marc_s has suggested in his comment.

Note, however, that, as the names of these two trigger types suggest, there's a fundamental difference between a BEFORE trigger and an INSTEAD OF one. While in both cases the trigger is executed at the time when the action determined by the statement that's invoked the trigger hasn't taken place, in case of the INSTEAD OF trigger the action is never supposed to take place at all. The real action that you need to be done must be done by the trigger itself. This is very unlike the BEFORE trigger functionality, where the statement is always due to execute, unless, of course, you explicitly roll it back.

But there's one other issue to address actually. As your Oracle script reveals, the trigger you need to convert uses another feature unsupported by SQL Server, which is that of FOR EACH ROW. There are no per-row triggers in SQL Server either, only per-statement ones. That means that you need to always keep in mind that the inserted data are a row set, not just a single row. That adds more complexity, although that'll probably conclude the list of things you need to account for.

So, it's really two things to solve then:

• replace the BEFORE functionality;

• replace the FOR EACH ROW functionality.

My attempt at solving these is below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  INSERT INTO sub (super_id)
  SELECT super_id FROM @new_super;
END;

This is how the above works:

1. The same number of rows as being inserted into sub1 is first added to super. The generated super_id values are stored in a temporary storage (a table variable called @new_super).

2. The newly inserted super_ids are now inserted into sub1.

Nothing too difficult really, but the above will only work if you have no other columns in sub1 than those you've specified in your question. If there are other columns, the above trigger will need to be a bit more complex.

The problem is to assign the new super_ids to every inserted row individually. One way to implement the mapping could be like below:

CREATE TRIGGER sub_trg
ON sub1
INSTEAD OF INSERT
AS
BEGIN
  DECLARE @new_super TABLE (
    rownum   int IDENTITY (1, 1),
    super_id int
  );
  INSERT INTO super (subtype_discriminator)
  OUTPUT INSERTED.super_id INTO @new_super (super_id)
  SELECT 'SUB1' FROM INSERTED;

  WITH enumerated AS (
    SELECT *, ROW_NUMBER() OVER (ORDER BY (SELECT 1)) AS rownum
    FROM inserted
  )
  INSERT INTO sub1 (super_id, other columns)
  SELECT n.super_id, i.other columns
  FROM enumerated AS i
  INNER JOIN @new_super AS n
  ON i.rownum = n.rownum;
END;

As you can see, an IDENTIY(1,1) column is added to @new_user, so the temporarily inserted super_id values will additionally be enumerated starting from 1. To provide the mapping between the new super_ids and the new data rows, the ROW_NUMBER function is used to enumerate the INSERTED rows as well. As a result, every row in the INSERTED set can now be linked to a single super_id and thus complemented to a full data row to be inserted into sub1.

Note that the order in which the new super_ids are inserted may not match the order in which they are assigned. I considered that a no-issue. All the new super rows generated are identical save for the IDs. So, all you need here is just to take one new super_id per new sub1 row.

If, however, the logic of inserting into super is more complex and for some reason you need to remember precisely which new super_id has been generated for which new sub row, you'll probably want to consider the mapping method discussed in this Stack Overflow question:

• Using merge..output to get mapping between source.id and target.id

Use the sizing utility classes...

For visualization and summary of PyTorch models, tensorboardX can also can be utilized.

You can execute:

$ mpicc -showme 

result :

gcc -I/Users/<USER_NAME>/openmpi-2.0.1/include -L/Users/<USER_NAME>/openmpi-2.0.1/lib -lmp

This command shows you the necessary libraries to compile mpicc

Example:

$ mpicc -g  -I/Users/<USER_NAME>/openmpi-2.0.1/include -o [nameExec] [objetcs.o...] [program.c] -lm


$ mpicc -g  -I/Users/<USER_NAME>/openmpi-2.0.1/include -o example file_object.o my_program.c otherlib.o -lm

this command generates executable with your program in example, you can execute :

$ ./example

public static long GetDirSize(string path)
{
    try
    {
        return Directory.EnumerateFiles(path).Sum(x => new FileInfo(x).Length)  
            +
               Directory.EnumerateDirectories(path).Sum(x => GetDirSize(x));
    }
    catch
    {
        return 0L;
    }
}

You can use the "Network" tab in the browser (shift+ctrl+i) or Firebug.
But an even better solution - in my opinion - is in addition to use an external program such as Fiddler to monitor/catch the traffic between browser and server.

Here's how to do it for multiple www to no-www server names (I used this for subdomains):

server {
        server_name 
             "~^www\.(sub1.example.com)$"
             "~^www\.(sub2.example.com)$"
             "~^www\.(sub3.example.com)$";
         return 301 $scheme://$1$request_uri ;
}

The full list of commands is available at http://your-jenkins/cli

The command for a clean shutdown is http://your-jenkins/safe-shutdown

You may also want to use http://your-jenkins/safe-restart

To start only stopped containers:

docker start $(docker ps -a -q -f status=exited)

(On windows it works in Powershell).

Assuming you don't need cross browser support (which is impossible without a plugin for IE), have you tried using svg as a background image?

Experimental stuff for sure, but thought I would mention it.

In addition to @KenM's answer, another important distinction is that, when loading in a saved object, you can assign the contents of an Rds file. Not so for Rda

> x <- 1:5
> save(x, file="x.Rda")
> saveRDS(x, file="x.Rds")
> rm(x)

## ASSIGN USING readRDS
> new_x1 <- readRDS("x.Rds")
> new_x1
[1] 1 2 3 4 5

## 'ASSIGN' USING load -- note the result
> new_x2 <- load("x.Rda")
loading in to  <environment: R_GlobalEnv> 
> new_x2
[1] "x"
# NOTE: `load()` simply returns the name of the objects loaded. Not the values. 
> x
[1] 1 2 3 4 5

For the SQL statement, you also have to specify the column list. For eg.

INSERT INTO tbl (idcol1,col2) VALUES ( value1,value2)

instead of

INSERT INTO tbl VALUES ( value1,value2)

Simple. On your code first, set the type of DateTime to DateTime?. So you can work with nullable DateTime type in database. Entity example:

public class Alarme
    {
        [Key]
        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        public int Id { get; set; }

        public DateTime? DataDisparado { get; set; }//.This allow you to work with nullable datetime in database.
        public DateTime? DataResolvido { get; set; }//.This allow you to work with nullable datetime in database.
        public long Latencia { get; set; }

        public bool Resolvido { get; set; }

        public int SensorId { get; set; }
        [ForeignKey("SensorId")]
        public virtual Sensor Sensor { get; set; }
    }

You can use something like ini_set('session.gc_maxlifetime', 28800); // 8 * 60 * 60 too.

e.preventDefault(); from https://developer.mozilla.org/en-US/docs/Web/API/event.preventDefault

Or have return false from your method.

You should override toString() method in your Dog class. which will be called when you use this object in sysout.

Since High Sierra, you need to use:

sudo chown -R $(whoami) $(brew --prefix)/*

This is because /usr/local can no longer be chowned

You have to initialize the vector of vectors to the appropriate size before accessing any elements. You can do it like this:

// assumes using std::vector for brevity
vector<vector<int>> matrix(RR, vector<int>(CC));

This creates a vector of RR size CC vectors, filled with 0.

In PostgreSQL this is typically simpler and faster (more performance optimization below):

SELECT DISTINCT ON (customer)
       id, customer, total
FROM   purchases
ORDER  BY customer, total DESC, id;

Or shorter (if not as clear) with ordinal numbers of output columns:

SELECT DISTINCT ON (2)
       id, customer, total
FROM   purchases
ORDER  BY 2, 3 DESC, 1;

If total can be NULL (won't hurt either way, but you'll want to match existing indexes):

...
ORDER  BY customer, total DESC NULLS LAST, id;

Major points

DISTINCT ON is a PostgreSQL extension of the standard (where only DISTINCT on the whole SELECT list is defined).

List any number of expressions in the DISTINCT ON clause, the combined row value defines duplicates. The manual:

Obviously, two rows are considered distinct if they differ in at least one column value. Null values are considered equal in this comparison.

Bold emphasis mine.

DISTINCT ON can be combined with ORDER BY. Leading expressions in ORDER BY must be in the set of expressions in DISTINCT ON, but you can rearrange order among those freely. Example.
You can add additional expressions to ORDER BY to pick a particular row from each group of peers. Or, as the manual puts it:

The DISTINCT ON expression(s) must match the leftmost ORDER BY expression(s). The ORDER BY clause will normally contain additional expression(s) that determine the desired precedence of rows within each DISTINCT ON group.

I added id as last item to break ties:
"Pick the row with the smallest id from each group sharing the highest total."

To order results in a way that disagrees with the sort order determining the first per group, you can nest above query in an outer query with another ORDER BY. Example.

If total can be NULL, you most probably want the row with the greatest non-null value. Add NULLS LAST like demonstrated. See:

• Sort by column ASC, but NULL values first?

The SELECT list is not constrained by expressions in DISTINCT ON or ORDER BY in any way. (Not needed in the simple case above):

• You don't have to include any of the expressions in DISTINCT ON or ORDER BY.

• You can include any other expression in the SELECT list. This is instrumental for replacing much more complex queries with subqueries and aggregate / window functions.

I tested with Postgres versions 8.3 – 13. But the feature has been there at least since version 7.1, so basically always.

Index

The perfect index for the above query would be a multi-column index spanning all three columns in matching sequence and with matching sort order:

CREATE INDEX purchases_3c_idx ON purchases (customer, total DESC, id);

May be too specialized. But use it if read performance for the particular query is crucial. If you have DESC NULLS LAST in the query, use the same in the index so that sort order matches and the index is applicable.

Effectiveness / Performance optimization

Weigh cost and benefit before creating tailored indexes for each query. The potential of above index largely depends on data distribution.

The index is used because it delivers pre-sorted data. In Postgres 9.2 or later the query can also benefit from an index only scan if the index is smaller than the underlying table. The index has to be scanned in its entirety, though.

For few rows per customer (high cardinality in column customer), this is very efficient. Even more so if you need sorted output anyway. The benefit shrinks with a growing number of rows per customer.
Ideally, you have enough work_mem to process the involved sort step in RAM and not spill to disk. But generally setting work_mem too high can have adverse effects. Consider SET LOCAL for exceptionally big queries. Find how much you need with EXPLAIN ANALYZE. Mention of "Disk:" in the sort step indicates the need for more:

• Configuration parameter work_mem in PostgreSQL on Linux
• Optimize simple query using ORDER BY date and text

For many rows per customer (low cardinality in column customer), a loose index scan (a.k.a. "skip scan") would be (much) more efficient, but that's not implemented up to Postgres 13. (An implementation for index-only scans is in development for Postgres 14. See here and here.)
For now, there are faster query techniques to substitute for this. In particular if you have a separate table holding unique customers, which is the typical use case. But also if you don't:

• Optimize GROUP BY query to retrieve latest row per user
• Optimize groupwise maximum query
• Query last N related rows per row

Benchmark

I had a simple benchmark here which is outdated by now. I replaced it with a detailed benchmark in this separate answer.

Instead of numpy or scipy, I would recommend pandas to do this more swiftly:

df['data'].rolling(3).mean()

This takes the moving average (MA) of 3 periods of the column "data". You can also calculate the shifted versions, for example the one that excludes the current cell (shifted one back) can be calculated easily as:

df['data'].shift(periods=1).rolling(3).mean()

Generate dates between two date fields

If you are aware with SQL CTE query, then this solution will helps you to solve your question

Here is example

We have dates in one table

Table Name: “testdate”

STARTDATE   ENDDATE
10/24/2012  10/24/2012
10/27/2012  10/29/2012
10/30/2012  10/30/2012

Require Result:

STARTDATE
10/24/2012
10/27/2012
10/28/2012
10/29/2012
10/30/2012

Solution:

WITH CTE AS
  (SELECT DISTINCT convert(varchar(10),StartTime, 101) AS StartTime,
                   datediff(dd,StartTime, endTime) AS diff
   FROM dbo.testdate
   UNION ALL SELECT StartTime,
                    diff - 1 AS diff
   FROM CTE
   WHERE diff<> 0)
SELECT DISTINCT DateAdd(dd,diff, StartTime) AS StartTime
FROM CTE

Explanation: CTE Recursive query explanation

• First part of query:
  
  SELECT DISTINCT convert(varchar(10), StartTime, 101) AS StartTime, datediff(dd, StartTime, endTime) AS diff FROM dbo.testdate
  
  Explanation: firstcolumn is “startdate”, second column is difference of start and end date in days and it will be consider as “diff” column

• Second part of query:
  
  UNION ALL SELECT StartTime, diff-1 AS diff FROM CTE WHERE diff<>0
  
  Explanation: Union all will inherit result of above query until result goes null, So “StartTime” result is inherit from generated CTE query, and from diff, decrease - 1, so its looks like 3, 2, and 1 until 0

For example

STARTDATE   DIFF
10/24/2012  0
10/27/2012  0
10/27/2012  1
10/27/2012  2
10/30/2012  0

Result Specification

STARTDATE       Specification
10/24/2012  --> From Record 1
10/27/2012  --> From Record 2
10/27/2012  --> From Record 2
10/27/2012  --> From Record 2
10/30/2012  --> From Record 3

• 3rd Part of Query
  
  

  SELECT DISTINCT DateAdd(dd,diff, StartTime) AS StartTime FROM CTE
  
  It will add day “diff” in “startdate” so result should be as below

Result

STARTDATE
10/24/2012
10/27/2012
10/28/2012
10/29/2012
10/30/2012

Here is a useful article by Michael J. Swart on the matter, which covers different patterns and antipatterns for implementing UPSERT in SQL Server:
https://michaeljswart.com/2017/07/sql-server-upsert-patterns-and-antipatterns/

It addresses associated concurrency issues (primary key violations, deadlocks) - all of the answers provided here yet are considered antipatterns in the article (except for the @Bridge solution using triggers, which is not covered there).

Here is an extract from the article with the solution preferred by the author:

Inside a serializable transaction with lock hints:

CREATE PROCEDURE s_AccountDetails_Upsert ( @Email nvarchar(4000), @Etc nvarchar(max) )
AS 
  SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
  BEGIN TRAN

    IF EXISTS ( SELECT * FROM dbo.AccountDetails WITH (UPDLOCK) WHERE Email = @Email )

      UPDATE dbo.AccountDetails
         SET Etc = @Etc
       WHERE Email = @Email;

    ELSE 

      INSERT dbo.AccountDetails ( Email, Etc )
      VALUES ( @Email, @Etc );

  COMMIT

There is also related question with answers here on stackoverflow: Insert Update stored proc on SQL Server

In your server.js :

var express   =     require("express");
var app       =     express();
app.use(express.static(__dirname + '/public'));

You have declared express and app separately, create a folder named 'public' or as you like, and yet you can access to these folder. In your template src, you have added the relative path from /public (or the name of your folder destiny to static files). Beware of the bars on the routes.

Here's another way of listing files inside a directory (using a different tool, not as efficient as some of the other answers).

cd "search_dir"
for [ z in `echo *` ]; do
    echo "$z"
done

echo * Outputs all files of the current directory. The for loop iterates over each file name and prints to stdout.

Additionally, If looking for directories inside the directory then place this inside the for loop:

if [ test -d $z ]; then
    echo "$z is a directory"
fi

test -d checks if the file is a directory.

this error is also caused by null pointer reference. if you are using a pointer who is not initialized then it causes this error.

to check either a pointer is initialized or not you can try something like

Class *pointer = new Class();
if(pointer!=nullptr){
    pointer->myFunction();
}

setInterval function is the one that has to be used. Here is an example for the same without any fancy fading option. Simple Javascript that does an image change every 30 seconds. I have assumed that the images were kept in a separate images folder and hence _images/ is present at the beginning of every image. You can have your own path as required to be set.

CODE:

var im = document.getElementById("img");

var images = ["_images/image1.jpg","_images/image2.jpg","_images/image3.jpg"];
var index=0;

function changeImage()
{
  im.setAttribute("src", images[index]);
  index++;
  if(index >= images.length)
  {
    index=0;
  }
}

setInterval(changeImage, 30000);

#include <string>
#include <sstream>
using namespace std;
string concatenate(std::string const& name, int i)

    return s.str();
}

Example for replacing LI elements

function (element) {
    let li = element.parentElement;
    let ul = li.parentNode;   
    if (li.nextSibling.nodeName === 'LI') {
        let li_replaced = ul.replaceChild(li, li.nextSibling);
        ul.insertBefore(li_replaced, li);
    }
}

showSoftInput was not working for me at all.

I figured I needed to set the input mode : android:windowSoftInputMode="stateVisible" (here in the Activity component in the manifest)

Hope this help!

It will show that message if you have code like this:

<form>
  <div style="display: none;">
    <input name="test" type="text" required/>
  </div>

  <input type="submit"/>
</form>

solution to this problem will depend on how the site should work

for example if you don't want the form to submit unless this field is required you should disable the submit button

so the js code to show the div should enable the submit button as well

you can hide the button too (should be disabled and hidden because if it's hidden but not disabled the user can submit the form with others way like press enter in any other field but if the button is disabled this won't happen

if you want the form to submit if the div is hidden you should disable any required input inside it and enable the inputs while you are showing the div

if someone need the codes to do so you should tell me exactly what you need

First close the eclipse then

Open CMD by Window Key + R or via Run as Admin

Follows the following step

del "%USERPROFILE%\.android\debug.keystore"
keytool -genkey -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android -keyalg RSA -validity 30000

after this restart eclipse.

Parameters and local variables are allocated on the stack (with reference types, the object lives on the heap and a variable in the stack references that object on the heap). The stack typically lives at the upper end of your address space and as it is used up it heads towards the bottom of the address space (i.e. towards zero).

Your process also has a heap, which lives at the bottom end of your process. As you allocate memory, this heap can grow towards the upper end of your address space. As you can see, there is a potential for the heap to "collide" with the stack (a bit like tectonic plates!!!).

The common cause for a stack overflow is a bad recursive call. Typically, this is caused when your recursive functions doesn't have the correct termination condition, so it ends up calling itself forever. Or when the termination condition is fine, it can be caused by requiring too many recursive calls before fulfilling it.

However, with GUI programming, it's possible to generate indirect recursion. For example, your app may be handling paint messages, and, whilst processing them, it may call a function that causes the system to send another paint message. Here you've not explicitly called yourself, but the OS/VM has done it for you.

To deal with them, you'll need to examine your code. If you've got functions that call themselves then check that you've got a terminating condition. If you have, then check that when calling the function you have at least modified one of the arguments, otherwise there'll be no visible change for the recursively called function and the terminating condition is useless. Also mind that your stack space can run out of memory before reaching a valid terminating condition, thus make sure your method can handle input values requiring more recursive calls.

If you've got no obvious recursive functions then check to see if you're calling any library functions that indirectly will cause your function to be called (like the implicit case above).

For what it is worth, i have ubuntu and many packages installed and it went in conflict with it.

For me the right answer was:

sudo -i -u postgres-xc
psql

It's platform-specific. But you can cast it to a known type.

printf("%lld\n", (long long) time(NULL));

Use LoadPatientRecords() after a successful insertion.

Try the below code

private void btnSubmit_Click(object sender, EventArgs e)
{
        if (btnSubmit.Text == "Clear")
        {
            btnSubmit.Text = "Submit";

            txtpFirstName.Focus();
        }
        else
        {
           btnSubmit.Text = "Clear";
           int result = AddPatientRecord();
           if (result > 0)
           {
               MessageBox.Show("Insert Successful");

               LoadPatientRecords();
           }
           else
               MessageBox.Show("Insert Fail");
         }
}

While I agree with the most voted answer, here is another way to keep all rows except the first:

dat <- tail(dat, -1)

This can also be accomplished using Hadley Wickham's dplyr package.

dat <- dat %>% slice(-1)

In your viewDidLoad, register at notification center to listen to this opened from background action

NotificationCenter.default.addObserver(self, selector:#selector(doSomething), name: NSNotification.Name.UIApplicationWillEnterForeground, object: nil)
        

Then add this function and perform needed action

func doSomething(){
    //...
}

Finally add this function to clean up the notification observer when your view controller is destroyed.

deinit {
    NotificationCenter.default.removeObserver(self)
}

My solution is put those imports in __init__.py of lib:

in file: __init__.py
import mod1

Then,

import lib
lib.mod1

would work fine.

You can use the new Object.fromEntries() method.

Example:

const array = [_x000D_
   {key: 'a', value: 'b', redundant: 'aaa'},_x000D_
   {key: 'x', value: 'y', redundant: 'zzz'}_x000D_
]_x000D_
_x000D_
const hash = Object.fromEntries(_x000D_
   array.map(e => [e.key, e.value])_x000D_
)_x000D_
_x000D_
console.log(hash) // {a: b, x: y}

To anyone with who is having this problem, its a typo error. Check your spelling of your struct delcerations and your struct

To check if a path is an existing file:

os.path.isfile(path)

Return True if path is an existing regular file. This follows symbolic links, so both islink() and isfile() can be true for the same path.

The following worked for me:

function print_link(link) {
    var mywindow = window.open(link, 'title', 'height=500,width=500');   
    mywindow.onload = function() { mywindow.print(); mywindow.close(); }
}

objectForKey: is an NSDictionary method. An NSDictionary is a collection class similar to an NSArray, except instead of using indexes, it uses keys to differentiate between items. A key is an arbitrary string you provide. No two objects can have the same key (just as no two objects in an NSArray can have the same index).

valueForKey: is a KVC method. It works with ANY class. valueForKey: allows you to access a property using a string for its name. So for instance, if I have an Account class with a property accountNumber, I can do the following:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setAccountNumber:anAccountNUmber];

NSNumber *anotherAccountNumber = [newAccount accountNumber];

Using KVC, I can access the property dynamically:

NSNumber *anAccountNumber = [NSNumber numberWithInt:12345];
Account *newAccount = [[Account alloc] init];

[newAccount setValue:anAccountNumber forKey:@"accountNumber"];

NSNumber *anotherAccountNumber = [newAccount valueForKey:@"accountNumber"];

Those are equivalent sets of statements.

I know you're thinking: wow, but sarcastically. KVC doesn't look all that useful. In fact, it looks "wordy". But when you want to change things at runtime, you can do lots of cool things that are much more difficult in other languages (but this is beyond the scope of your question).

If you want to learn more about KVC, there are many tutorials if you Google especially at Scott Stevenson's blog. You can also check out the NSKeyValueCoding Protocol Reference.

Hope that helps.

Here's a quick and dirty method that does what you want in a generic way. You'll need to add exception handling and you'll probably want to cache the BeanInfo types in a weakhashmap.

public Map<String, Object> getNonNullProperties(final Object thingy) {
    final Map<String, Object> nonNullProperties = new TreeMap<String, Object>();
    try {
        final BeanInfo beanInfo = Introspector.getBeanInfo(thingy
                .getClass());
        for (final PropertyDescriptor descriptor : beanInfo
                .getPropertyDescriptors()) {
            try {
                final Object propertyValue = descriptor.getReadMethod()
                        .invoke(thingy);
                if (propertyValue != null) {
                    nonNullProperties.put(descriptor.getName(),
                            propertyValue);
                }
            } catch (final IllegalArgumentException e) {
                // handle this please
            } catch (final IllegalAccessException e) {
                // and this also
            } catch (final InvocationTargetException e) {
                // and this, too
            }
        }
    } catch (final IntrospectionException e) {
        // do something sensible here
    }
    return nonNullProperties;
}

Turns out that the post (or rather the whole table) was locked by the very same connection that I tried to update the post with.

I had a opened record set of the post that was created by:

Set RecSet = Conn.Execute()

This type of recordset is supposed to be read-only and when I was using MS Access as database it did not lock anything. But apparently this type of record set did lock something on MS SQL Server 2012 because when I added these lines of code before executing the UPDATE SQL statement...

RecSet.Close
Set RecSet = Nothing

...everything worked just fine.

So bottom line is to be careful with opened record sets - even if they are read-only they could lock your table from updates.

You should consult the documentation of whatever library is throwing the exception, to see how to get an error message out of its exceptions.

Alternatively, a good way to debug this kind of thing is to say:

except Exception, e:
    print dir(e)

to see what properties e has - you'll probably find it has a message property or similar.

Square brackets:

jsObj['key' + i] = 'example' + 1;

In JavaScript, all arrays are objects, but not all objects are arrays. The primary difference (and one that's pretty hard to mimic with straight JavaScript and plain objects) is that array instances maintain the length property so that it reflects one plus the numeric value of the property whose name is numeric and whose value, when converted to a number, is the largest of all such properties. That sounds really weird, but it just means that given an array instance, the properties with names like "0", "5", "207", and so on, are all treated specially in that their existence determines the value of length. And, on top of that, the value of length can be set to remove such properties. Setting the length of an array to 0 effectively removes all properties whose names look like whole numbers.

OK, so that's what makes an array special. All of that, however, has nothing at all to do with how the JavaScript [ ] operator works. That operator is an object property access mechanism which works on any object. It's important to note in that regard that numeric array property names are not special as far as simple property access goes. They're just strings that happen to look like numbers, but JavaScript object property names can be any sort of string you like.

Thus, the way the [ ] operator works in a for loop iterating through an array:

for (var i = 0; i < myArray.length; ++i) {
  var value = myArray[i]; // property access
  // ...
}

is really no different from the way [ ] works when accessing a property whose name is some computed string:

var value = jsObj["key" + i];

The [ ] operator there is doing precisely the same thing in both instances. The fact that in one case the object involved happens to be an array is unimportant, in other words.

When setting property values using [ ], the story is the same except for the special behavior around maintaining the length property. If you set a property with a numeric key on an array instance:

myArray[200] = 5;

then (assuming that "200" is the biggest numeric property name) the length property will be updated to 201 as a side-effect of the property assignment. If the same thing is done to a plain object, however:

myObj[200] = 5;

there's no such side-effect. The property called "200" of both the array and the object will be set to the value 5 in otherwise the exact same way.

One might think that because that length behavior is kind-of handy, you might as well make all objects instances of the Array constructor instead of plain objects. There's nothing directly wrong about that (though it can be confusing, especially for people familiar with some other languages, for some properties to be included in the length but not others). However, if you're working with JSON serialization (a fairly common thing), understand that array instances are serialized to JSON in a way that only involves the numerically-named properties. Other properties added to the array will never appear in the serialized JSON form. So for example:

var obj = [];
obj[0] = "hello world";
obj["something"] = 5000;

var objJSON = JSON.stringify(obj);

the value of "objJSON" will be a string containing just ["hello world"]; the "something" property will be lost.

ES2015:

If you're able to use ES6 JavaScript features, you can use Computed Property Names to handle this very easily:

var key = 'DYNAMIC_KEY',
    obj = {
        [key]: 'ES6!'
    };

console.log(obj);
// > { 'DYNAMIC_KEY': 'ES6!' }

I was tired of searching on google how to run iReport with java 8.

I did everything as said on the Internet,But I don't know why they weren't work for me.

Then I Change My Computer JDK Current Version form 1.8 to 1.7 Using Registry Editor.

Now it work fine.

To Change Current Version

Start => Type regedit (Press Enter) => HKEY_LOCAL_MACHINE => SOFTWARE => JavaSoft => Java Development Kit => Change Key Value of CurrentVersion From 1.8 to 1.7

This could be updated to ES6 with arrow functions and look like:

getFeed().then(data => vm.feed = data);

If you wish to use the async function, you could also do like that:

async function myFunction(){
    vm.feed = await getFeed();
    // do whatever you need with vm.feed below
 }

put this line in parent construct : $this->load->database();

function  __construct() {
    parent::__construct();
    $this->load->library('lib_name');
    $model=array('model_name');
    $this->load->model($model);
    $this->load->database();
}

this way.. it should work..

Want to add a difference:

Trying to acess a inexistent key gives runtime error in Dictionary but no problem in hashtable as it returns null instead of error.

e.g.

       //No strict type declaration
        Hashtable hash = new Hashtable();
        hash.Add(1, "One");
        hash.Add(2, "Two");
        hash.Add(3, "Three");
        hash.Add(4, "Four");
        hash.Add(5, "Five"); 
        hash.Add(6, "Six");
        hash.Add(7, "Seven");
        hash.Add(8, "Eight");
        hash.Add(9, "Nine");
        hash.Add("Ten", 10);// No error as no strict type

        for(int i=0;i<=hash.Count;i++)//=>No error for index 0
        {
            //Can be accessed through indexers
            Console.WriteLine(hash[i]);
        }
        Console.WriteLine(hash["Ten"]);//=> No error in Has Table

here no error for key 0 & also for key "ten"(note: t is small)

//Strict type declaration
        Dictionary<int,string> dictionary= new Dictionary<int, string>();
        dictionary.Add(1, "One");
        dictionary.Add(2, "Two");
        dictionary.Add(3, "Three");
        dictionary.Add(4, "Four");
        dictionary.Add(5, "Five");
        dictionary.Add(6, "Six");
        dictionary.Add(7, "Seven");
        dictionary.Add(8, "Eight");
        dictionary.Add(9, "Nine");
        //dictionary.Add("Ten", 10);// error as only key, value pair of type int, string can be added

        //for i=0, key doesn't  exist error
        for (int i = 1; i <= dictionary.Count; i++)
        {
            //Can be accessed through indexers
            Console.WriteLine(dictionary[i]);
        }
        //Error : The given key was not present in the dictionary.
        //Console.WriteLine(dictionary[10]);

here error for key 0 & also for key 10 as both are inexistent in dictionary, runtime error, while try to acess.

You can use Process.Start:

Dim url As String = “http://www.example.com“

Process.Start(url)

This should open whichever browser is set as default on the system.

This can be achieved by wrapping the image and search bar in their own container and floating the image to the left with a specific width.

This takes the image out of the "flow" which means that any items rendered in normal flow will not adjust their positioning to take account of this.

To make the "in flow" searchBar appear correctly positioned to the right of the image you give it a left padding equal to the width of the image plus a gutter.

The effect is to make the image a fixed width while the rest of the container block is fluidly filled up by the search bar.

<div class="container">
  <img src="img/logo.png"/>
  <div id="searchBar">
    <input type="text" />
  </div>
</div>

and the css

.container {
  width: 100%;
}

.container img {
  width: 50px;
  float: left;
}

.searchBar {
  padding-left: 60px;
}

I also see you're storing your passwords in plaintext (a big security no-no!). Consider using the built-in auth system instead.

Html.Hidden('name', 'value') creates a hidden tag with name = 'name' and value = 'value'.

Html.HiddenFor(x => x.nameProp) creates a hidden tag with a name = 'nameProp' and value = x.nameProp.

At face value these appear to do similar things, with one just more convenient than the other. But its actual value is for model binding. When MVC tries to associate the html to the model, it needs to have the name of the property, and for Html.Hidden, we chose 'name', and not 'nameProp', and thus the binding wouldn't work. You'd have to have a custom binding object, or get the values from the form data. If you are redisplaying the page, you'd have to set the model to the values again.

So you can use Html.Hidden, but if you get the name wrong, or if you change the property name in the model, the auto binding will fail when you submit the form. But by using a type checked expression, you'll get code completion, and when you change the property name, you will get a compile time error. And then you are guaranteed to have the correct name in the form.

One of the better features of MVC.

You can either have the newly inserted ID being output to the SSMS console like this:

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

You can use this also from e.g. C#, when you need to get the ID back to your calling app - just execute the SQL query with .ExecuteScalar() (instead of .ExecuteNonQuery()) to read the resulting ID back.

Or if you need to capture the newly inserted ID inside T-SQL (e.g. for later further processing), you need to create a table variable:

DECLARE @OutputTbl TABLE (ID INT)

INSERT INTO MyTable(Name, Address, PhoneNo)
OUTPUT INSERTED.ID INTO @OutputTbl(ID)
VALUES ('Yatrix', '1234 Address Stuff', '1112223333')

This way, you can put multiple values into @OutputTbl and do further processing on those. You could also use a "regular" temporary table (#temp) or even a "real" persistent table as your "output target" here.
