The HTML2PDF and HTML2PS that was originally mentioned in opening post was talking about a 2009 package with this link

But there is a better HTML2PDF

It is based on TCPDF though it is partly in French.

You can have table headers or footers that repeat on the pages and have page numbers and total pages. See its examples. I have been using it for over three years and recommend it.

Programmatic options for controlling services:

• Native code can used, "Starting a Service". Maximum control with minimum dependencies but the most work.
• WMI: Win32_Service has a StartService method. This is good for cases where you need to be able to perform other processing (e.g. to select which service).
• PowerShell: execute Start-Service via RunspaceInvoke or by creating your own Runspace and using its CreatePipeline method to execute. This is good for cases where you need to be able to perform other processing (e.g. to select which service) with a much easier coding model than WMI, but depends on PSH being installed.
• A .NET application can use ServiceController

import types
import yourmodule

print([getattr(yourmodule, a) for a in dir(yourmodule)
  if isinstance(getattr(yourmodule, a), types.FunctionType)])

By Using underscore.js

var arr = [{id:1,name:'a'},{id:2,name:'b'},{id:3,name:'c'}];

var resultArr = _.reject(arr,{id:3});

console.log(resultArr);

The result will be :: [{id:1name:'a'},{id:2,name:'c'}]

If speed and memory is no problem, dom4j is a really good option. If you need speed, using a StAX parser like Woodstox is the right way, but you have to write more code to get things done and you have to get used to process XML in streams.

If you want to have parameter values (not only @p_linq_0 but also their values) too, you can use IDbCommandInterceptor and add some logging to ReaderExecuted method.

Fragments that are hard coded in XML, cannot be replaced. If you need to replace a fragment with another, you should have added them dynamically, first of all.

Note: R.id.fragment_container is a layout or container of your choice in the activity you are bringing the fragment to.

// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();

// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack if needed
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);

// Commit the transaction
transaction.commit();

yourPictureBox.ImageLocation = "http://www.gravatar.com/avatar/6810d91caff032b202c50701dd3af745?d=identicon&r=PG"

In case you get a compiler error for __attribute__((noinline)), you can just try:

noinline int func(int arg)
{
    ....
}

>>> def duplicates(lst, item):
...   return [i for i, x in enumerate(lst) if x == item]
... 
>>> duplicates(List, "A")
[0, 2]

To get all duplicates, you can use the below method, but it is not very efficient. If efficiency is important you should consider Ignacio's solution instead.

>>> dict((x, duplicates(List, x)) for x in set(List) if List.count(x) > 1)
{'A': [0, 2]}

As for solving it using the index method of list instead, that method takes a second optional argument indicating where to start, so you could just repeatedly call it with the previous index plus 1.

>>> List.index("A")
0
>>> List.index("A", 1)
2

EDIT Fixed issue raised in comments.

Just open Node.js commmand promt as run as administrator

You can try below code to solve your problem:

By default, first option select: jQuery('.select').find('option')[0].selected=true;

Inside <td>, use style="border-left:1px solid #colour;"

When you do len(df['column name']) you are just getting one number, namely the number of rows in the DataFrame (i.e., the length of the column itself). If you want to apply len to each element in the column, use df['column name'].map(len). So try

df[df['column name'].map(len) < 2]

You're declaring everything in the parent page. So the references to window and document are to the parent page's. If you want to do stuff to the iframe's, use iframe || iframe.contentWindow to access its window, and iframe.contentDocument || iframe.contentWindow.document to access its document.

There's a word for what's happening, possibly "lexical scope": What is lexical scope?

The only context of a scope is this. And in your example, the owner of the method is doc, which is the iframe's document. Other than that, anything that's accessed in this function that uses known objects are the parent's (if not declared in the function). It would be a different story if the function were declared in a different place, but it's declared in the parent page.

This is how I would write it:

(function () {
  var dom, win, doc, where, iframe;

  iframe = document.createElement('iframe');
  iframe.src = "javascript:false";

  where = document.getElementsByTagName('script')[0];
  where.parentNode.insertBefore(iframe, where);

  win = iframe.contentWindow || iframe;
  doc = iframe.contentDocument || iframe.contentWindow.document;

  doc.open();
  doc._l = (function (w, d) {
    return function () {
      w.vanishing_global = new Date().getTime();

      var js = d.createElement("script");
      js.src = 'test-vanishing-global.js?' + w.vanishing_global;

      w.name = "foobar";
      d.foobar = "foobar:" + Math.random();
      d.foobar = "barfoo:" + Math.random();
      d.body.appendChild(js);
    };
  })(win, doc);
  doc.write('<body onload="document._l();"></body>');
  doc.close();
})();

The aliasing of win and doc as w and d aren't necessary, it just might make it less confusing because of the misunderstanding of scopes. This way, they are parameters and you have to reference them to access the iframe's stuff. If you want to access the parent's, you still use window and document.

I'm not sure what the implications are of adding methods to a document (doc in this case), but it might make more sense to set the _l method on win. That way, things can be run without a prefix...such as <body onload="_l();"></body>

For what it's worth, I just had to handle this in my ASP.NET MVC 3 application. Here is the code block I used in the Global.asax file to handle this for all requests.

    protected void Application_BeginRequest()
    {
        //NOTE: Stopping IE from being a caching whore
        HttpContext.Current.Response.Cache.SetAllowResponseInBrowserHistory(false);
        HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
        HttpContext.Current.Response.Cache.SetNoStore();
        Response.Cache.SetExpires(DateTime.Now);
        Response.Cache.SetValidUntilExpires(true);
    }

Just use array.push(something);. Javascript arrays are like ArrayLists in this respect - they can be treated like they have a flexible length (unlike java arrays).

Define a maximum size. Then, compute a resize ratio by taking min(maxwidth/width, maxheight/height).

The proper size is oldsize*ratio.

There is of course also a library method to do this: the method Image.thumbnail.
Below is an (edited) example from the PIL documentation.

import os, sys
import Image

size = 128, 128

for infile in sys.argv[1:]:
    outfile = os.path.splitext(infile)[0] + ".thumbnail"
    if infile != outfile:
        try:
            im = Image.open(infile)
            im.thumbnail(size, Image.ANTIALIAS)
            im.save(outfile, "JPEG")
        except IOError:
            print "cannot create thumbnail for '%s'" % infile

open: function () {

    var win = $(window);

    $(this).parent().css({
        position: 'absolute',
        left: (win.width() - $(this).parent().outerWidth()) / 2,
        top: (win.height() - $(this).parent().outerHeight()) / 2
    });
}

When I got this error:

#145 - Table '.\engine\phpbb3_posts' is marked as crashed and should be repaired

I ran this command in PhpMyAdmin to fix it:

REPAIR TABLE phpbb3_posts;

onchange="$('select')[$('select').index(this)+1].focus()"

This may work if your next field is another select.

mipadi's answer didn't quite work for me, I needed to do this :

git checkout --ours path/to/file.bin

or, to keep the version being merged in:

git checkout --theirs path/to/file.bin

then

git add path/to/file.bin

And then I was able to do "git mergetool" again and continue onto the next conflict.

Just finished understanding Peek and Keep and had same confusion initially. The confusion arises becauses TempData behaves differently under different condition. You can watch this video which explains the Keep and Peek with demonstration https://www.facebook.com/video.php?v=689393794478113

Tempdata helps to preserve values for a single request and CAN ALSO preserve values for the next request depending on 4 conditions”.

If we understand these 4 points you would see more clarity.Below is a diagram with all 4 conditions, read the third and fourth point which talks about Peek and Keep.

Condition 1 (Not read):- If you set a “TempData” inside your action and if you do not read it in your view then “TempData” will be persisted for the next request.

Condition 2 ( Normal Read) :- If you read the “TempData” normally like the below code it will not persist for the next request.

string str = TempData["MyData"];

Even if you are displaying it’s a normal read like the code below.

@TempData["MyData"];

Condition 3 (Read and Keep) :- If you read the “TempData” and call the “Keep” method it will be persisted.

@TempData["MyData"];
TempData.Keep("MyData");

Condition 4 ( Peek and Read) :- If you read “TempData” by using the “Peek” method it will persist for the next request.

string str = TempData.Peek("Td").ToString();

Reference :- http://www.codeproject.com/Articles/818493/MVC-Tempdata-Peek-and-Keep-confusion

Basic:

string[] myString = new string[]{"string1", "string2"};

or

string[] myString = new string[4];
myString[0] = "string1"; // etc.

Advanced: From a List

list<string> = new list<string>(); 
//... read this in from somewhere
string[] myString = list.ToArray();

From StringCollection

StringCollection sc = new StringCollection();
/// read in from file or something
string[] myString = sc.ToArray();

Another reason this can sometimes come up is due to a misconfiguration in your docker-compose (if you're using it) whereby the mysql container is not on the same network that your app servers are on.

If the network flag is forgotten or incorrect docker won't add the mysql to the DNS for the app server and therefore throw an error like this.

This is the only way I don't get NullPointerException for the instance variables of that particular fragment classes. This might be helpful for others who stuck at the same thing. In the onOptionsItemSelected(), I coded the below way:

if(viewPager.getCurrentItem() == 0) {
    FragmentClass1 frag1 = (FragmentClass1)viewPager
                            .getAdapter()
                            .instantiateItem(viewPager, viewPager.getCurrentItem());
    frag1.updateList(text); 
} else if(viewPager.getCurrentItem() == 1) {
    FragmentClass2 frag2 = (FragRecentApps)viewPager
                            .getAdapter()
                            .instantiateItem(viewPager, viewPager.getCurrentItem());
    frag2.updateList(text);
}

I've used Aspose.Words to do mail merge in .NET. I believe that they also have a Java version.

Java 8 supports default methods in interfaces. And in JDK 8 a lot of old interfaces now have new default methods. For example, now in CharSequence we have chars and codePoints methods.
If source level of your project is lower than 1.8, then compiler doesn't allow you to use default methods in interfaces. So it cannot compile classes that directly on indirectly depend on this interfaces.
If I get your problem right, then you have two solutions. First solution is to rollback to JDK 7, then you will use old CharSequence interface without default methods. Second solution is to set source level of your project to 1.8, then your compiler will not complain about default methods in interfaces.

The sender is the control that the action is for (say OnClick, it's the button).

The EventArgs are arguments that the implementor of this event may find useful. With OnClick it contains nothing good, but in some events, like say in a GridView 'SelectedIndexChanged', it will contain the new index, or some other useful data.

What Chris is saying is you can do this:

protected void someButton_Click (object sender, EventArgs ea)
{
    Button someButton = sender as Button;
    if(someButton != null)
    {
        someButton.Text = "I was clicked!";
    }
}

There is an assembly instruction called BSWAP that will do the swap for you, extremely fast. You can read about it here.

Visual Studio, or more precisely the Visual C++ runtime library, has platform intrinsics for this, called _byteswap_ushort(), _byteswap_ulong(), and _byteswap_int64(). Similar should exist for other platforms, but I'm not aware of what they would be called.

give this style to td: width: 1%;

Maybe these

• JArgs command line option parsing suite for Java - this tiny project provides a convenient, compact, pre-packaged and comprehensively documented suite of command line option parsers for the use of Java programmers. Initially, parsing compatible with GNU-style 'getopt' is provided.

• ritopt, The Ultimate Options Parser for Java - Although, several command line option standards have been preposed, ritopt follows the conventions prescribed in the opt package.

Yes, you can even change it by triggering an event

<input type='text' name='pass'  onclick="(this.type='password')" />


<input type="text" placeholder="date" onfocusin="(this.type='date')" onfocusout="(this.type='text')">

You can do something like this:

jQuery.fn.existsWithValue = function() { 
    return this.length && this.val().length; 
}

if ($(selector).existsWithValue()) {
        // Do something
}

I am doing like below for multiple and independent conditions and it works like charm:

<div ng-style="{{valueFromJS}} === 'Hello' ? {'color': 'red'} : {'color': ''} && valueFromNG-Repeat === '{{dayOfToday}}' ? {'font-weight': 'bold'} : {'font-weight': 'normal'}"></div>

Additionally to those above, I added __file__ for the name so the picture and Python file get the same names. I also added few arguments to make It look better:

# Saves a PNG file of the current graph to the folder and updates it every time
# (nameOfimage, dpi=(sizeOfimage),Keeps_Labels_From_Disappearing)
plt.savefig(__file__+".png",dpi=(250), bbox_inches='tight')
# Hard coded name: './test.png'

As far as I know, there's a good library called localeplanet for Localization and Internationalization in JavaScript. Furthermore, I think it's native and has no dependencies to other libraries (e.g. jQuery)

Here's the website of library: http://www.localeplanet.com/

Also look at this article by Mozilla, you can find very good method and algorithms for client-side translation: http://blog.mozilla.org/webdev/2011/10/06/i18njs-internationalize-your-javascript-with-a-little-help-from-json-and-the-server/

The common part of all those articles/libraries is that they use a i18n class and a get method (in some ways also defining an smaller function name like _) for retrieving/converting the key to the value. In my explaining the key means that string you want to translate and the value means translated string.
Then, you just need a JSON document to store key's and value's.

For example:

var _ = document.webL10n.get;
alert(_('test'));

And here the JSON:

{ test: "blah blah" }

I believe using current popular libraries solutions is a good approach.

If the board is n × n then there are n rows, n columns, and 2 diagonals. Check each of those for all-X's or all-O's to find a winner.

If it only takes x < n consecutive squares to win, then it's a little more complicated. The most obvious solution is to check each x × x square for a winner. Here's some code that demonstrates that.

(I didn't actually test this *cough*, but it did compile on the first try, yay me!)

public class TicTacToe
{
    public enum Square { X, O, NONE }

    /**
     * Returns the winning player, or NONE if the game has
     * finished without a winner, or null if the game is unfinished.
     */
    public Square findWinner(Square[][] board, int lengthToWin) {
        // Check each lengthToWin x lengthToWin board for a winner.    
        for (int top = 0; top <= board.length - lengthToWin; ++top) {
            int bottom = top + lengthToWin - 1;

            for (int left = 0; left <= board.length - lengthToWin; ++left) {
                int right = left + lengthToWin - 1;

                // Check each row.
                nextRow: for (int row = top; row <= bottom; ++row) {
                    if (board[row][left] == Square.NONE) {
                        continue;
                    }

                    for (int col = left; col <= right; ++col) {
                        if (board[row][col] != board[row][left]) {

                }

                // Check each column.

                    if (board[top][col] == Square.NONE) {

                            continue nextCol;
                        }
                    }

                    return board[top][col];
                }

                // Check top-left to bottom-right diagonal.
                diag1: if (board[top][left] != Square.NONE) {
                    for (int i = 1; i < lengthToWin; ++i) {
                        if (board[top+i][left+i] != board[top][left]) {
                            break diag1;

Try using:

console.log($("#"+d));

This will remove the extra quotes you were using.

string input = "super exemple of string key : text I want to keep - end of my string";
var match = Regex.Match(input, @"key : (.+?)-").Groups[1].Value;

or with just string operations

var start = input.IndexOf("key : ") + 6;
var match2 = input.Substring(start, input.IndexOf("-") - start);

After installing and configuring Hadoop, you can quickly run the command netstat -tulpn

to find the ports open. In the new version of Hadoop 3.1.3 the ports are as follows:-

localhost:8042 Hadoop, localhost:9870 HDFS, localhost:8088 YARN

The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();

names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

or just read the line and parse the value as an Integer.

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());

names = new String[nnames];
for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

The limit was the clue for my code, but I had to specify it like this:

use: [
  {
    loader: 'url-loader',
    options: {
      limit: 8192,
    },
  },
],

If you want to easily know the screen density and size of an Android device, you can use this free app (no permission required): https://market.android.com/details?id=com.jotabout.screeninfo

this work for me

1. git init

2. git add --all

3.git commit -m "name"

4.git push origin master --force

The read(1) utility along with output redirection of the ls(1) command will do what you want.

I had the same problem. I am using Phonegap and Jquery mobile, for Adroid devices. To resize properly I had to set a timeout:

$(window).bind('orientationchange',function(e) {
  fixOrientation();
});

$(window).bind('resize',function(e) {
  fixOrientation();
});

function fixOrientation() {

    setTimeout(function() {

        var windowWidth = window.innerWidth;

        $('div[data-role="page"]').width(windowWidth);
        $('div[data-role="header"]').width(windowWidth);
        $('div[data-role="content"]').width(windowWidth-30);
        $('div[data-role="footer"]').width(windowWidth);

    },500);
}

I fixed it myself, the key is android:width="0dip"

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="4dip"
    android:layout_weight="1">

    <LinearLayout 
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:padding="4dip">

        <TextView
            android:id="@+id/reviewItemEntityName"

        <ImageView

I created https://yt-embed.herokuapp.com/ to simplify this. The usage is direct, from the examples above:

[![Everything Is AWESOME](https://yt-embed.herokuapp.com/embed?v=StTqXEQ2l-Y)](https://www.youtube.com/watch?v=StTqXEQ2l-Y "Everything Is AWESOME")

Will result in:

Just make a call to: https://yt-embed.herokuapp.com/embed?v=[video_id] as the image instead of https://img.youtube.com/vi/.

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

Just use padding top and bottom, it will automatically center the content vertically.

Just to document if someone has the same problem...

In my situation I've been using :uuid fields, and the above answers does not work to my case, because rails 5 are creating a column using :bigint instead :uuid:

add_reference :uploads, :user, index: true, type: :uuid

Reference: Active Record Postgresql UUID

Here is what works for me on Swift 3

let _ = (dict[key].map { $0 as? String } ?? "")

In general, you're better off validating URLs using built-in library or framework functions, rather than rolling your own regular expressions to do this - see What is the best regular expression to check if a string is a valid URL for details.

If you are keen on doing this, though, check out this question:

Getting parts of a URL (Regex)

Then, once you're satisfied with the URL (by whatever means you used to validate it), you could either use a simple "endswith" type string operator to check the extension, or a simple regex like

(?i)\.(jpg|png|gif)$

The certification installation step whatever mentioned here is correct https://stackoverflow.com/a/35200795/865220

But if you are having a pain of individually having to enable SSL Proxy for each and every new url like me, then to enable for all host names just enter * into the host and port names list in the SSL Proxying Settings like this:

In my case, my site was hosted on shared hosting and there was a resource over usage not even relating to my database, thus my database was locked down, the hosting panel was Plesk

Another version, with some benefits below.

$sum = ArrayHelper::copyKeys($arr[0]);

foreach ($arr as $item) {
    ArrayHelper::addArrays($sum, $item);
}


class ArrayHelper {

    public function addArrays(Array &$to, Array $from) {
        foreach ($from as $key=>$value) {
            $to[$key] += $value;
        }
    }

    public function copyKeys(Array $from, $init=0) {
        return array_fill_keys(array_keys($from), $init);
    }

}

I wanted to combine the best of Gumbo's, Graviton's, and Chris J's answer with the following goals so I could use this in my app:

a) Initialize the 'sum' array keys outside of the loop (Gumbo). Should help with performance on very large arrays (not tested yet!). Eliminates notices.

b) Main logic is easy to understand without hitting the manuals. (Graviton, Chris J).

c) Solve the more general problem of adding the values of any two arrays with the same keys and make it less dependent on the sub-array structure.

Unlike Gumbo's solution, you could reuse this in cases where the values are not in sub arrays. Imagine in the example below that $arr1 and $arr2 are not hard-coded, but are being returned as the result of calling a function inside a loop.

$arr1 = array(
    'gozhi' => 2,
    'uzorong' => 1,
    'ngangla' => 4,
    'langthel' => 5
);

$arr2 = array(
   'gozhi' => 5,
   'uzorong' => 0,
   'ngangla' => 3,
   'langthel' => 2
);

$sum = ArrayHelper::copyKeys($arr1);

ArrayHelper::addArrays($sum, $arr1);
ArrayHelper::addArrays($sum, $arr2);

I've searched the minimal solution possible to do PHP + WebSockets during hours, until I found this article:

Super simple PHP WebSocket example

It doesn't require any third-party library.

Here is how to do it: create a index.html containing this:

<html>
<body>
    <div id="root"></div>
    <script>
        var host = 'ws://<<<IP_OF_YOUR_SERVER>>>:12345/websockets.php';
        var socket = new WebSocket(host);
        socket.onmessage = function(e) {
            document.getElementById('root').innerHTML = e.data;
        };
    </script>
</body>
</html>

and open it in the browser, just after you have launched php websockets.php in the command-line (yes, it will be an event loop, constantly running PHP script), with this websockets.php file.

The same way you do it in other db system, you can use the name of the db for identifying double named tables. unique tablenames can used directly.

select * from ttt.table_name;

or if table name in all attached databases is unique

select * from my_unique_table_name;

But I think the of of sqlite-shell is only for manual lookup or manual data manipulation and therefor this way is more inconsequential

normally you would use sqlite-command-line in a script

CSS will skip over style declarations it doesn't understand. Mozilla-based browsers will not understand -webkit-prefixed declarations, and WebKit-based browsers will not understand -moz-prefixed declarations.

Because of this, we can simply declare width twice:

elem {
    width: 100%;
    width: -moz-available;          /* WebKit-based browsers will ignore this. */
    width: -webkit-fill-available;  /* Mozilla-based browsers will ignore this. */
    width: fill-available;
}

The width: 100% declared at the start will be used by browsers which ignore both the -moz and -webkit-prefixed declarations or do not support -moz-available or -webkit-fill-available.

this is how you can parse iCal files with javascript

    function calParse(str) {

        function parse() {
            var obj = {};
            while(str.length) {
                var p = str.shift().split(":");
                var k = p.shift(), p = p.join();
                switch(k) {
                    case "BEGIN":
                        obj[p] = parse();
                        break;
                    case "END":
                        return obj;
                    default:
                        obj[k] = p;
                }
            }
            return obj;
        }
        str = str.replace(/\n /g, " ").split("\n");
        return parse().VCALENDAR;
    }

    example = 
    'BEGIN:VCALENDAR\n'+
    'VERSION:2.0\n'+
    'PRODID:-//hacksw/handcal//NONSGML v1.0//EN\n'+
    'BEGIN:VEVENT\n'+
    'DTSTART:19970714T170000Z\n'+
    'DTEND:19970715T035959Z\n'+
    'SUMMARY:Bastille Day Party\n'+
    'END:VEVENT\n'+
    'END:VCALENDAR\n'


    cal = calParse(example);
    alert(cal.VEVENT.SUMMARY);

I just ran into this issue and after an hour of screwing around realized I had added an aspx file to my product that had the same name as one of my Linq-To-Sql classes.
Class and Page where "Queue".
Changed the page to QueueMgr.aspx and everything built just fine.

From Microsoft documentation:

PAGEIOLATCH_SH

Occurs when a task is waiting on a latch for a buffer that is in an I/O request. The latch request is in Shared mode. Long waits may indicate problems with the disk subsystem.

In practice, this almost always happens due to large scans over big tables. It almost never happens in queries that use indexes efficiently.

If your query is like this:

Select * from <table> where <col1> = <value> order by <PrimaryKey>

, check that you have a composite index on (col1, col_primary_key).

If you don't have one, then you'll need either a full INDEX SCAN if the PRIMARY KEY is chosen, or a SORT if an index on col1 is chosen.

Both of them are very disk I/O consuming operations on large tables.

I'd like to write explicitly two methods which allow accomplishing this in pure JavaScript:

document.getElementsByClassName('realClasssName').length

Note 1: Argument of this method needs a string with the real class name, without the dot at the begin of this string.

document.querySelectorAll('.realClasssName').length

Note 2: Argument of this method needs a string with the real class name but with the dot at the begin of this string.

Note 3: This method works also with any other CSS selectors, not only with class selector. So it's more universal.

I also write one method, but using two name conventions to solve this problem using jQuery:

jQuery('.realClasssName').length

or

$('.realClasssName').length

Note 4: Here we also have to remember about the dot, before the class name, and we can also use other CSS selectors.

When you import a module (or a member of it) for the first time, the code inside the module is executed sequentially like any other code; e.g., it is not treated any differently that the body of a function. An import is just a command like any other (assignment, a function call, def, class). Assuming your imports occur at the top of the script, then here's what's happening:

• When you try to import World from world, the world script gets executed.
• The world script imports Field, which causes the entities.field script to get executed.
• This process continues until you reach the entities.post script because you tried to import Post
• The entities.post script causes physics module to be executed because it tries to import PostBody
• Finally, physics tries to import Post from entities.post
• I'm not sure whether the entities.post module exists in memory yet, but it really doesn't matter. Either the module is not in memory, or the module doesn't yet have a Post member because it hasn't finished executing to define Post
• Either way, an error occurs because Post is not there to be imported

So no, it's not "working further up in the call stack". This is a stack trace of where the error occurred, which means it errored out trying to import Post in that class. You shouldn't use circular imports. At best, it has negligible benefit (typically, no benefit), and it causes problems like this. It burdens any developer maintaining it, forcing them to walk on egg shells to avoid breaking it. Refactor your module organization.

Here is my example. Hope it make sense.

public static void excuteCommand(String filePath) throws IOException{
    File file = new File(filePath);
    if(!file.isFile()){
        throw new IllegalArgumentException("The file " + filePath + " does not exist");
    }
    if(isLinux()){
        Runtime.getRuntime().exec(new String[] {"/bin/sh", "-c", filePath}, null);
    }else if(isWindows()){
        Runtime.getRuntime().exec("cmd /c start " + filePath);
    }
}
public static boolean isLinux(){
    String os = System.getProperty("os.name");  
    return os.toLowerCase().indexOf("linux") >= 0;
}

public static boolean isWindows(){
    String os = System.getProperty("os.name");
    return os.toLowerCase().indexOf("windows") >= 0;
}

here is the perfect way...

private void func_trd(String sender)
{

    try
    {
        imgh.LoadImages_R_Randomiz(this, "01", groupBox, randomizerB.Value); // normal code

        ThreadStart ts = delegate
        {
            ExecuteInForeground(sender);
        };

        Thread nt = new Thread(ts);
        nt.IsBackground = true;

        nt.Start();

    }
    catch (Exception)
    {

    }
}

private void ExecuteInForeground(string name)
{
     //whatever ur function
    MessageBox.Show(name);
}

You can just "call" your model with an array of the correct shape:

model(np.array([[6.7, 3.3, 5.7, 2.5]]))

Full example:

from sklearn.datasets import load_iris
from tensorflow.keras.layers import Dense
from tensorflow.keras.models import Sequential
import numpy as np

X, y = load_iris(return_X_y=True)

model = Sequential([
    Dense(16, activation='relu'),
    Dense(32, activation='relu'),
    Dense(1)])

model.compile(loss='mean_absolute_error', optimizer='adam')

history = model.fit(X, y, epochs=10, verbose=0)

print(model(np.array([[6.7, 3.3, 5.7, 2.5]])))

<tf.Tensor: shape=(1, 1), dtype=float64, numpy=array([[1.92517677]])>

if you have in your layout activity_main

<android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

you have to put

in your Activity this code

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    toolbar.setBackgroundColor(Color.CYAN);
}

I had the same issue. I installed gitx instead.

You can install gitx from here.

http://rowanj.github.io/gitx/

Download the package and install it. After that open the gitk from spotlight search, goto the top left corner. Click on GitX and enable the terminal usage.

Goto your repo and simply type:

$ gitx --all

It will open the Gui.

User manual: http://gitx.frim.nl/user_manual.html

The gdi32 library is already installed on your computer, few programs will run without it. Your compiler will (if installed properly) normally come with an import library, which is what the linker uses to make a binding between your program and the file in the system. (In the unlikely case that your compiler does not come with import libraries for the system libs, you will need to download the Microsoft Windows Platform SDK.)

To link with gdi32:

This will reliably work with MinGW-gcc for all system libraries (it should work if you use any other compiler too, but I can't talk about things I've not tried). You can also write the library's full name, but writing libgdi32.a has no advantage over gdi32 other than being more type work.
If it does not work for some reason, you may have to provide a different name (for example the library is named gdi32.lib for MSVC).

For libraries in some odd locations or project subfolders, you will need to provide a proper pathname (click on the "..." button for a file select dialog).

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

This is a very late response, but adds some detail on the previous answers

When it comes to calling static methods in PHP from another static method on the same class, it is important to differentiate between self and the class name.

Take for instance this code:

class static_test_class {
    public static function test() {
        echo "Original class\n";
    }

    public static function run($use_self) {
        if($use_self) {
            self::test();
        } else {
            $class = get_called_class();
            $class::test(); 
        }
    }
}

class extended_static_test_class extends static_test_class {
    public static function test() {
        echo "Extended class\n";
    }
}

extended_static_test_class::run(true);
extended_static_test_class::run(false);

The output of this code is:

Original class

Extended class

This is because self refers to the class the code is in, rather than the class of the code it is being called from.

If you want to use a method defined on a class which inherits the original class, you need to use something like:

$class = get_called_class();
$class::function_name(); 

Cells(1,1).Value2 = "'123,456"

note the single apostrophe before the number - this will signal to excel that whatever follows has to be interpreted as text.

The ternary operator RETURNS one of two values. Or, it can execute one of two statements based on its condition, but that's generally not a good idea, as it can lead to unintended side-effects.

bar ? () : baz();

In this case, the () does nothing, while baz does something. But you've only made the code less clear. I'd go for more verbose code that's clearer and easier to maintain.

Further, this makes little sense at all:

var foo = bar ? () : baz();

since () has no return type (it's void) and baz has a return type that's unknown at the point of call in this sample. If they don't agree, the compiler will complain, and loudly.

look at String.indexOf and String.substring.

Make sure you check for -1 for indexOf.

I have to say that you are taking on a lot in just 10 weeks, I just finished a semester of Java programming at Indiana University Southeast, and I don't think I have begun to scratch the surface yet. Java is a very strict language in that its syntax is very tough to get a handle on if you have no programming experience at all. I will offer these pieces of advice go to www.bluej.org and down load there, Java compiler it is said to be the easiest to work with and that most college's use this. It is also, what we learned on and from what I know now I can say, they are right. Java is an object oriented language, and Bluej gives you a great understanding of objects. They also show you how to design, classes, methods, array, array list, hash maps, all of that is on this site and it is free. I hope this helps and good luck with your challange.

pg_dump -s databasename -t tablename -U user -h host -p port > tablename.sql

this will limit the schema dump to the table "tablename" of "databasename"

removing JAVA_HOME and JAVA_JRE from environment variable is resolved the issue.

Using parameters in batch files: %0 and %9

Batch files can refer to the words passed in as parameters with the tokens: %0 to %9.

%0 is the program name as it was called.
%1 is the first command line parameter
%2 is the second command line parameter
and so on till %9.

parameters passed in on the commandline must be alphanumeric characters and delimited by spaces. Since %0 is the program name as it was called, in DOS %0 will be empty for AUTOEXEC.BAT if started at boot time.

Example:

Put the following command in a batch file called mybatch.bat:

@echo off
@echo hello %1 %2
pause

Invoking the batch file like this: mybatch john billy would output:

hello john billy

Get more than 9 parameters for a batch file, use: %*

The Percent Star token %* means "the rest of the parameters". You can use a for loop to grab them, as defined here:

http://www.robvanderwoude.com/parameters.php

Notes about delimiters for batch parameters

Some characters in the command line parameters are ignored by batch files, depending on the DOS version, whether they are "escaped" or not, and often depending on their location in the command line:

commas (",") are replaced by spaces, unless they are part of a string in 
double quotes

semicolons (";") are replaced by spaces, unless they are part of a string in 
double quotes

"=" characters are sometimes replaced by spaces, not if they are part of a 
string in double quotes

the first forward slash ("/") is replaced by a space only if it immediately 
follows the command, without a leading space

multiple spaces are replaced by a single space, unless they are part of a 
string in double quotes

tabs are replaced by a single space

leading spaces before the first command line argument are ignored

var token = 'spo';

switch(token){
    case ( (token.match(/spo/) )? token : undefined ) :
       console.log('MATCHED')    
    break;;
    default:
       console.log('NO MATCH')
    break;;
}

--> If the match is made the ternary expression returns the original token
----> The original token is evaluated by case

--> If the match is not made the ternary returns undefined
----> Case evaluates the token against undefined which hopefully your token is not.

The ternary test can be anything for instance in your case

( !!~ base_url_string.indexOf('xxx.dev.yyy.com') )? xxx.dev.yyy.com : undefined 

===========================================

(token.match(/spo/) )? token : undefined ) 

is a ternary expression.

The test in this case is token.match(/spo/) which states the match the string held in token against the regex expression /spo/ ( which is the literal string spo in this case ).

If the expression and the string match it results in true and returns token ( which is the string the switch statement is operating on ).

Obviously token === token so the switch statement is matched and the case evaluated

It is easier to understand if you look at it in layers and understand that the turnery test is evaluated "BEFORE" the switch statement so that the switch statement only sees the results of the test.

I'm able to get the Class of the generic type this way:

class MyList<T> {
  Class<T> clazz = (Class<T>) DAOUtil.getTypeArguments(MyList.class, this.getClass()).get(0);
}

You need two functions from this file: http://code.google.com/p/hibernate-generic-dao/source/browse/trunk/dao/src/main/java/com/googlecode/genericdao/dao/DAOUtil.java

You can remove the time part of a date by using TRUNC.

select field,datetime_field 
  from database
 where datetime_field >= trunc(sysdate-1,'DD');

That query will give you all rows with dates starting from yesterday. Note the second argument to trunc(). You can use this to truncate any part of the date.

If your datetime_fied contains '2011-05-04 08:23:54', the following date will be returned

trunc(datetime_field, 'HH24') => 2011-05-04 08:00:00
trunc(datetime_field, 'DD')   => 2011-05-04 00:00:00
trunc(datetime_field, 'MM')   => 2011-05-01 00:00:00
trunc(datetime_field, 'YYYY') => 2011-00-01 00:00:00

with GNU-grep you could just say

grep --context=10 ...

It is used in the stack unwiding tables, which you can see for instance in the assembly output of my answer to another question. As mentioned on that answer, its use is defined by the Itanium C++ ABI, where it is called the Personality Routine.

The reason it "works" by defining it as a global NULL void pointer is probably because nothing is throwing an exception. When something tries to throw an exception, then you will see it misbehave.

Of course, if nothing is using exceptions, you can disable them with -fno-exceptions (and if nothing is using RTTI, you can also add -fno-rtti). If you are using them, you have to (as other answers already noted) link with g++ instead of gcc, which will add -lstdc++ for you.

It appears that tkFileDialog.askdirectory should work. documentation

Quick fix - make sure all variables which do not get initialized when they are created (eg var num : Int? vs var num = 5) have either a ? or !.

Long answer (reccomended) - read the doc as per mprivat suggests...

In Angular 7 the for loop is like below

var values = [
        {
            "name":"Thomas",
            "password":"thomas"
        },
        { 
            "name":"linda",
            "password":"linda"
        }];

for (let item of values)
{
}

You could write a custom validation attribute:

public class CombinedMinLengthAttribute: ValidationAttribute
{
    public CombinedMinLengthAttribute(int minLength, params string[] propertyNames)
    {
        this.PropertyNames = propertyNames;
        this.MinLength = minLength;
    }

    public string[] PropertyNames { get; private set; }
    public int MinLength { get; private set; }

    protected override ValidationResult IsValid(object value, ValidationContext validationContext)
    {
        var properties = this.PropertyNames.Select(validationContext.ObjectType.GetProperty);
        var values = properties.Select(p => p.GetValue(validationContext.ObjectInstance, null)).OfType<string>();
        var totalLength = values.Sum(x => x.Length) + Convert.ToString(value).Length;
        if (totalLength < this.MinLength)
        {
            return new ValidationResult(this.FormatErrorMessage(validationContext.DisplayName));
        }
        return null;
    }
}

and then you might have a view model and decorate one of its properties with it:

public class MyViewModel
{
    [CombinedMinLength(20, "Bar", "Baz", ErrorMessage = "The combined minimum length of the Foo, Bar and Baz properties should be longer than 20")]
    public string Foo { get; set; }
    public string Bar { get; set; }
    public string Baz { get; set; }
}

Another way to accomplish this if you still have that issue is by doing the following :

• Clear all the Table header text leave it empty.
• On the Reports “Header” section add textboxes inside a rectangle , each textbox will represent a column header for the table.
• As this rectangle is on the Reports Header section it will display on all report pages.

Thanks, Sufian.

Update:

This is not the best answer anymore, please follow gregers' advice.

New answer:

Use Weinre.

Old answer:

You can now use Safari for remote debugging. But it requires iOS 6.

Here is a quick translation of http://html5-mobile.de/blog/ios6-remote-debugging-web-inspector

1. Connect your iDevice via USB with your Mac
2. Open Safari on your Mac and activate the dev tools
3. On your iDevice: go to settings > safari > advanced and activate the web inspector
4. Go to any website with your iDevice
5. On your Mac: Open the developer menu and chose the site from your iDevice (its at the top Safari Menu)

As pointed out by Simons answer one need to turn off private browsing to make remote debugging work.

Settings > Safari > Private Browsing > OFF

I was getting e.data.indexOf is not a function error, after debugging it, I found that it was actually a TypeError, which meant, indexOf() being a function is applicable to strings, so I typecasted the data like the following and then used the indexOf() method to make it work

e.data.toString().indexOf('<stringToBeMatchedToPosition>')

Not sure if my answer was accurate to the question, but yes shared my opinion as i faced a similar kind of situation.

I overcame the same problem by installing MySQL-python library using pip. You can see the message displayed on my console when I first changed my database settings in settings.py and executed makemigrations command(The solution is following the below message, just see that).

Ok I've done it. I'm sharing this code in case someone else will need it:

super.draw(canvas, mapView, true);

Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);

paint.setStrokeWidth(2);
paint.setColor(android.graphics.Color.RED);     
paint.setStyle(Paint.Style.FILL_AND_STROKE);
paint.setAntiAlias(true);

Point point1_draw = new Point();        
Point point2_draw = new Point();    
Point point3_draw = new Point();

mapView.getProjection().toPixels(point1, point1_draw);
mapView.getProjection().toPixels(point2, point2_draw);
mapView.getProjection().toPixels(point3, point3_draw);

Path path = new Path();
path.setFillType(Path.FillType.EVEN_ODD);
path.moveTo(point1_draw.x,point1_draw.y);
path.lineTo(point2_draw.x,point2_draw.y);
path.lineTo(point3_draw.x,point3_draw.y);
path.lineTo(point1_draw.x,point1_draw.y);
path.close();

canvas.drawPath(path, paint);

//canvas.drawLine(point1_draw.x,point1_draw.y,point2_draw.x,point2_draw.y, paint);

return true;

Thanks for the hint Nicolas!

SELECT *
FROM myTable

Or use CHARINDEX http://msdn.microsoft.com/en-us/library/aa258228(v=SQL.80).aspx

For variable argument functions like printf and scanf, the arguments are promoted, for example, any smaller integer types are promoted to int, float is promoted to double.

scanf takes parameters of pointers, so the promotion rule takes no effect. It must use %f for float* and %lf for double*.

printf will never see a float argument, float is always promoted to double. The format specifier is %f. But C99 also says %lf is the same as %f in printf:

C99 §7.19.6.1 The fprintf function

l (ell) Specifies that a following d, i, o, u, x, or X conversion specifier applies to a long int or unsigned long int argument; that a following n conversion specifier applies to a pointer to a long int argument; that a following c conversion specifier applies to a wint_t argument; that a following s conversion specifier applies to a pointer to a wchar_t argument; or has no effect on a following a, A, e, E, f, F, g, or G conversion specifier.

Here is what I have been using:

public static HashMap<String, Object> parse(String json) {
    JsonObject object = (JsonObject) parser.parse(json);
    Set<Map.Entry<String, JsonElement>> set = object.entrySet();
    Iterator<Map.Entry<String, JsonElement>> iterator = set.iterator();
    HashMap<String, Object> map = new HashMap<String, Object>();
    while (iterator.hasNext()) {
        Map.Entry<String, JsonElement> entry = iterator.next();
        String key = entry.getKey();
        JsonElement value = entry.getValue();
        if (!value.isJsonPrimitive()) {
            map.put(key, parse(value.toString()));
        } else {
            map.put(key, value.getAsString());
        }
    }
    return map;
}

If you want to use a multiline EditText with imeOptions, try:

android:inputType="textImeMultiLine"

I had to set

Container_height = Element1_height = Element2_height

.Container {
    position: relative;
}

.ElementOne, .Container ,.ElementTwo{
    width: 283px;
    height: 71px;
}

.ElementOne {
    position:absolute;
}

.ElementTwo{
    position:absolute;
}

Use can use z-index to set which one to be on top.

in React v16.8+ function component, you can use useState() to create a function state that lets you update the parent state, then pass it on to child as a props attribute, then inside the child component you can trigger the parent state function, the following is a working snippet:

_x000D_
function Timer({ setParentCounter }) {_x000D_

I´ve done a tiny solution using only jQuery.

First, you need to put an additional class to your <div class="modal-body"> I called "ativa-scroll", so it becomes something like this:

<div class="modal-body ativa-scroll">

So now just put this piece of code on your page, near your JS loading:

<script type="text/javascript">
  $(document).ready(ajustamodal);
  $(window).resize(ajustamodal);
  function ajustamodal() {
    var altura = $(window).height() - 155; //value corresponding to the modal heading + footer
    $(".ativa-scroll").css({"height":altura,"overflow-y":"auto"});
  }
</script>

I works perfectly for me, also in a responsive way! :)

If cleaning the solution didn't work and for anybody who see's this question and tried moving a project or renaming.

Open Package manager console and type "dotnet restore".

For some reason, setting all the correct permissions did not help in my case. I had a file db.bak that I was not able to restore due to the 5(Access is denied.) error. The file was placed in the same folder as several other backup files and all the permissions were identical to other files. I was able to restore all the other files except this db.bak file. I even tried to change the SQL Server service log on user — still the same result. I've tried copying the file with no effect.

Then I attempted to just create an identical file by executing

type db.bak > db2.bak

instead of copying the file. And voila it worked! db2.bak restored successfully.

I suspect that some other problems with reading the backup file may be erroniously reported as 5(Access is denied.) by MS SQL.

It's a syntax for array references - you need to use (&array) to clarify to the compiler that you want a reference to an array, rather than the (invalid) array of references int & array[100];.

EDIT: Some clarification.

void foo(int * x);
void foo(int x[100]);
void foo(int x[]);

These three are different ways of declaring the same function. They're all treated as taking an int * parameter, you can pass any size array to them.

void foo(int (&x)[100]);

This only accepts arrays of 100 integers. You can safely use sizeof on x

void foo(int & x[100]); // error

This is parsed as an "array of references" - which isn't legal.

POSIX sed (and for example OS X's sed, the sed below) require i to be followed by a backslash and a newline. Also at least OS X's sed does not include a newline after the inserted text:

$ seq 3|gsed '2i1.5'
1
1.5
2
3
$ seq 3|sed '2i1.5'
sed: 1: "2i1.5": command i expects \ followed by text
$ seq 3|sed $'2i\\\n1.5'
1
1.52
3
$ seq 3|sed $'2i\\\n1.5\n'
1
1.5
2
3

To replace a line, you can use the c (change) or s (substitute) commands with a numeric address:

$ seq 3|sed $'2c\\\n1.5\n'
1
1.5
3
$ seq 3|gsed '2c1.5'
1
1.5
3
$ seq 3|sed '2s/.*/1.5/'
1
1.5
3

Alternatives using awk:

$ seq 3|awk 'NR==2{print 1.5}1'
1
1.5
2
3
$ seq 3|awk '{print NR==2?1.5:$0}'
1
1.5
3

awk interprets backslashes in variables passed with -v but not in variables passed using ENVIRON:

$ seq 3|awk -v v='a\ba' '{print NR==2?v:$0}'
1
a
3
$ seq 3|v='a\ba' awk '{print NR==2?ENVIRON["v"]:$0}'
1
a\ba
3

Both ENVIRON and -v are defined by POSIX.

Save it to file and run with:

# bash filename.sh

Search for "Objective-C Generated Interface Header Name" in the Build Settings of the target you're trying to build (let's say it's MyApp-Swift.h), and import the value of this setting (#import "MyApp-Swift.h") in the source file where you're trying to access your Swift APIs.

The default value for this field is $(SWIFT_MODULE_NAME)-Swift.h. You can see it if you double-click in the value field of the "Objective-C Generated Interface Header Name" setting.

Also, if you have dashes in your module name (let's say it's My-App), then in the $(SWIFT_MODULE_NAME) all dashes will be replaced with underscores. So then you'll have to add #import "My_App-Swift.h".

I think there is serialization problem, you can find exact error just need to add below code in service config in <configuration> section.

After config update "App_tracelog.svclog" file will create, where your service exist just need to open .svclog file and find red color line on left side panel which is error and see its description for more info.

I hope this will help to find your error.

In your example, you can't: the 5px margin is added to the bounding box of div#two and div#three effectively making their width and height 100% of parent + 5px, which will overflow.

You can use padding on the parent Element to ensure there's 5px of space inside its border:

<style>
    html, body {width:100%;height:100%;margin:0;padding:0;}
    .border {border:1px solid black;}
    #one {padding:5px;width:500px;height:300px;}
    #two {width:100%;height:50px;}
    #three {width:100px;height:100%;}
</style>

EDIT: In testing, removing the width:100% from div#two will actually let it work properly as divs are block-level and will always fill their parents' widths by default. That should clear your first case if you'd like to use margin.

Just use a two color background image:

<div style="width:100%; background:url('images/bkgmid.png');
       background-size: cover;">
content
</div>

I hope following program will solve your problem

You need Optional.isPresent() and orElse(). Your snippet won;t work because it doesn't return anything if not present.

The point of Optional is to return it from the method.

A typedef allows the programmer to define one Objective-C type as another. For example,

typedef int Counter; defines the type Counter to be equivalent to the int type. This drastically improves code readability.

EOF is -1 because that's how it's defined. The name is provided by the standard library headers that you #include. They make it equal to -1 because it has to be something that can't be mistaken for an actual byte read by getchar(). getchar() reports the values of actual bytes using positive number (0 up to 255 inclusive), so -1 works fine for this.

The != operator means "not equal". 0 stands for false, and anything else stands for true. So what happens is, we call the getchar() function, and compare the result to -1 (EOF). If the result was not equal to EOF, then the result is true, because things that are not equal are not equal. If the result was equal to EOF, then the result is false, because things that are equal are not (not equal).

The call to getchar() returns EOF when you reach the "end of file". As far as C is concerned, the 'standard input' (the data you are giving to your program by typing in the command window) is just like a file. Of course, you can always type more, so you need an explicit way to say "I'm done". On Windows systems, this is control-Z. On Unix systems, this is control-D.

The example in the book is not "wrong". It depends on what you actually want to do. Reading until EOF means that you read everything, until the user says "I'm done", and then you can't read any more. Reading until '\n' means that you read a line of input. Reading until '\0' is a bad idea if you expect the user to type the input, because it is either hard or impossible to produce this byte with a keyboard at the command prompt :)

I found json_reformat to be very handy. So I just did the following:

curl http://127.0.0.1:5000/people/api.json | json_reformat

that's it!

Right now there is no view:clear command. For laravel 4 this can probably help you: https://gist.github.com/cjonstrup/8228165

Disabling caching can be done by skipping blade. View caching is done because blade compiling each time is a waste of time.

The return statements should place in one line. Or the other option is to remove the curly brackets that bound the HTML statement.

example:

return posts.map((post, index) =>
    <div key={index}>
      <h3>{post.title}</h3>
      <p>{post.body}</p>
    </div>
);

Both VS Code extensions can be used:

1. 'Bookmarks'
2. 'Numbered Bookmarks'

Personally, I'm suggesting: Numbered Bookmarks, with 'navigate through all files' option:

1. ctrl + Shift + P in VS Code
2. In newly open field, type: Open User Settings
3. Paste this key/value: "numberedBookmarks.navigateThroughAllFiles": "allowDuplicates" (allow duplicates of bookmarks),
4. Or, paste this key/value: "numberedBookmarks.navigateThroughAllFiles": "replace"

NOTE

Either way, be careful with shortcuts (Ctrl+1, Ctrl+Shift+1,..) that are already assigned.

Personally, mine were in 2 conflicts, with:

1. VS Code shortcuts, that already exists,
2. Ditto clipboard (I've got paste on each call of bookmark)

First, the ++ operator takes precedence over the * operator, and the () operators take precedence over everything else.

Second, the ++number operator is the same as the number++ operator if you're not assigning them to anything. The difference is number++ returns number and then increments number, and ++number increments first and then returns it.

Third, by increasing the value of a pointer, you're incrementing it by the sizeof its contents, that is you're incrementing it as if you were iterating in an array.

So, to sum it all up:

ptr++;    // Pointer moves to the next int position (as if it was an array)
++ptr;    // Pointer moves to the next int position (as if it was an array)
++*ptr;   // The value of ptr is incremented
++(*ptr); // The value of ptr is incremented
++*(ptr); // The value of ptr is incremented
*ptr++;   // Pointer moves to the next int position (as if it was an array). But returns the old content
(*ptr)++; // The value of ptr is incremented
*(ptr)++; // Pointer moves to the next int position (as if it was an array). But returns the old content
*++ptr;   // Pointer moves to the next int position, and then get's accessed, with your code, segfault
*(++ptr); // Pointer moves to the next int position, and then get's accessed, with your code, segfault

As there are a lot of cases in here, I might have made some mistake, please correct me if I'm wrong.

EDIT:

So I was wrong, the precedence is a little more complicated than what I wrote, view it here: http://en.cppreference.com/w/cpp/language/operator_precedence

For anyone trying to do this in asp.net core. You can use claims.

public class CustomEmailProvider : IUserIdProvider
{
    public virtual string GetUserId(HubConnectionContext connection)
    {
        return connection.User?.FindFirst(ClaimTypes.Email)?.Value;
    }
}

Any identifier can be used, but it must be unique. If you use a name identifier for example, it means if there are multiple users with the same name as the recipient, the message would be delivered to them as well. I have chosen email because it is unique to every user.

Then register the service in the startup class.

services.AddSingleton<IUserIdProvider, CustomEmailProvider>();

Next. Add the claims during user registration.

var result = await _userManager.CreateAsync(user, Model.Password);
if (result.Succeeded)
{
    await _userManager.AddClaimAsync(user, new Claim(ClaimTypes.Email, Model.Email));
}

To send message to the specific user.

public class ChatHub : Hub
{
    public async Task SendMessage(string receiver, string message)
    {
        await Clients.User(receiver).SendAsync("ReceiveMessage", message);
    }
}

Note: The message sender won't be notified the message is sent. If you want a notification on the sender's end. Change the SendMessage method to this.

public async Task SendMessage(string sender, string receiver, string message)
{
    await Clients.Users(sender, receiver).SendAsync("ReceiveMessage", message);
}

These steps are only necessary if you need to change the default identifier. Otherwise, skip to the last step where you can simply send messages by passing userIds or connectionIds to SendMessage. For more

I'm new in ASP.NET MVC. I faced the same problem, the following is my workable in my Erorr.vbhtml (it work if you only need to log the error using Elmah log)

@ModelType System.Web.Mvc.HandleErrorInfo

    @Code
        ViewData("Title") = "Error"
        Dim item As HandleErrorInfo = CType(Model, HandleErrorInfo)
        //To log error with Elmah
        Elmah.ErrorLog.GetDefault(HttpContext.Current).Log(New Elmah.Error(Model.Exception, HttpContext.Current))
    End Code

<h2>
    Sorry, an error occurred while processing your request.<br />

    @item.ActionName<br />
    @item.ControllerName<br />
    @item.Exception.Message
</h2> 

It is simply!

try this function

function navigate(divId) {
$j('html, body').animate({ scrollTop: $j("#"+divId).offset().top }, 1500);
}

Pass the div id as parameter it will work I am using it already

For the most recent version of Angular as of this post, it seems you must first create a MatDialogConfig object and pass it as a second parameter to dialog.open() because Typescript expects the second parameter to be of type MatDialogConfig.

const matDialogConfig = new MatDialogConfig();
matDialogConfig.width = "600px";
matDialogConfig.height = "480px";
this.dialog.open(MyDialogComponent, matDialogConfig);

Created working Plunker for this. https://plnkr.co/edit/vR9aGoCwoOUL9tevIEen $('#console').append("<br/>"+$('#test_s :selected').text())

from pyspark.sql.types import IntegerType
data_df = data_df.withColumn("Plays", data_df["Plays"].cast(IntegerType()))
data_df = data_df.withColumn("drafts", data_df["drafts"].cast(IntegerType()))

You can run loop for each column but this is the simplest way to convert string column into integer.

Suppose you have service reference of the name localhost in your web.config so you can go as follows

localhost.Service objWebService = newlocalhost.Service();
localhost.AuthSoapHd objAuthSoapHeader = newlocalhost.AuthSoapHd();
string strUsrName =ConfigurationManager.AppSettings["UserName"];
string strPassword =ConfigurationManager.AppSettings["Password"];

objAuthSoapHeader.strUserName = strUsrName;
objAuthSoapHeader.strPassword = strPassword;

objWebService.AuthSoapHdValue =objAuthSoapHeader;
string str = objWebService.HelloWorld();

Response.Write(str);

The best answer I found on internet:

SELECT case when trim(TRANSLATE(col1, '0123456789-,.', ' ')) is null
            then 'numeric'
            else 'alpha'
       end
FROM tab1;

Will be like this:

 function rmv_val($var)
 {
     return(!($var == 'strawberry'));
 }

 $array = array('apple', 'orange', 'strawberry', 'blueberry', 'kiwi');

 $array_res = array_filter($array, "rmv_val");

Check if string is positive digit (integer) and alphabet

You may use str.isdigit() and str.isalpha() to check whether given string is positive integer and alphabet respectively.

Sample Results:

# For alphabet
>>> 'A'.isdigit()
False
>>> 'A'.isalpha()
True

# For digit
>>> '1'.isdigit()
True
>>> '1'.isalpha()
False

Check for strings as positive/negative - integer/float

str.isdigit() returns False if the string is a negative number or a float number. For example:

# returns `False` for float
>>> '123.3'.isdigit()
False
# returns `False` for negative number
>>> '-123'.isdigit()
False

If you want to also check for the negative integers and float, then you may write a custom function to check for it as:

def is_number(n):
    try:
        float(n)   # Type-casting the string to `float`.
                   # If string is not a valid `float`, 
                   # it'll raise `ValueError` exception
    except ValueError:
        return False
    return True

Sample Run:

>>> is_number('123')    # positive integer number
True

>>> is_number('123.4')  # positive float number
True
 
>>> is_number('-123')   # negative integer number
True

>>> is_number('-123.4') # negative `float` number
True

>>> is_number('abc')    # `False` for "some random" string
False

Discard "NaN" (not a number) strings while checking for number

The above functions will return True for the "NAN" (Not a number) string because for Python it is valid float representing it is not a number. For example:

>>> is_number('NaN')
True

In order to check whether the number is "NaN", you may use math.isnan() as:

>>> import math
>>> nan_num = float('nan')

>>> math.isnan(nan_num)
True

Or if you don't want to import additional library to check this, then you may simply check it via comparing it with itself using ==. Python returns False when nan float is compared with itself. For example:

# `nan_num` variable is taken from above example
>>> nan_num == nan_num
False

Hence, above function is_number can be updated to return False for "NaN" as:

def is_number(n):
    is_number = True
    try:
        num = float(n)
        # check for "nan" floats
        is_number = num == num   # or use `math.isnan(num)`
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('Nan')   # not a number "Nan" string
False

>>> is_number('nan')   # not a number string "nan" with all lower cased
False

>>> is_number('123')   # positive integer
True

>>> is_number('-123')  # negative integer
True

>>> is_number('-1.12') # negative `float`
True

>>> is_number('abc')   # "some random" string
False

Allow Complex Number like "1+2j" to be treated as valid number

The above function will still return you False for the complex numbers. If you want your is_number function to treat complex numbers as valid number, then you need to type cast your passed string to complex() instead of float(). Then your is_number function will look like:

def is_number(n):
    is_number = True
    try:
        #      v type-casting the number here as `complex`, instead of `float`
        num = complex(n)
        is_number = num == num
    except ValueError:
        is_number = False
    return is_number

Sample Run:

>>> is_number('1+2j')    # Valid 
True                     #      : complex number 

>>> is_number('1+ 2j')   # Invalid 
False                    #      : string with space in complex number represetantion
                         #        is treated as invalid complex number

>>> is_number('123')     # Valid
True                     #      : positive integer

>>> is_number('-123')    # Valid 
True                     #      : negative integer

>>> is_number('abc')     # Invalid 
False                    #      : some random string, not a valid number

>>> is_number('nan')     # Invalid
False                    #      : not a number "nan" string

PS: Each operation for each check depending on the type of number comes with additional overhead. Choose the version of is_number function which fits your requirement.

This sounds like the file is embedded within your application.

You should be using getClass().getResource("/path/to/your/resource.txt"), which returns an URL or getClass().getResourceAsStream("/path/to/your/resource.txt");

If it's not an embedded resource, then you need to know the relative path from your application's execution context to where your file exists

ddlutils is my best choice:http://db.apache.org/ddlutils/api/org/apache/ddlutils/platform/SqlBuilder.html

here is create example(groovy):

Platform platform  = PlatformFactory.createNewPlatformInstance("oracle");//db2,...
//create schema    
def db =        new Database();
def t = new Table(name:"t1",description:"XXX");
def col1 = new Column(primaryKey:true,name:"id",type:"bigint",required:true);
t.addColumn(col1);
t.addColumn(new Column(name:"c2",type:"DECIMAL",size:"8,2"));
t.addColumn( new Column(name:"c3",type:"varchar"));
t.addColumn(new Column(name:"c4",type:"TIMESTAMP",description:"date"));        
db.addTable(t);
println platform.getCreateModelSql(db, false, false)

//you can read Table Object from  platform.readModelFromDatabase(....)
def sqlbuilder = platform.getSqlBuilder();
println "insert:"+sqlbuilder.getInsertSql(t,["id":1,c2:3],false);

The original generation scheme for UUIDs was to concatenate the UUID version with the MAC address of the computer that is generating the UUID, and with the number of 100-nanosecond intervals since the adoption of the Gregorian calendar in the West. By representing a single point in space (the computer) and time (the number of intervals), the chance of a collision in values is effectively nil.

For postgres, I found it easier and more accurate to use the

date_trunc

function, like:

select name, sum(count), date_trunc('minute',timestamp) as timestamp
FROM table
WHERE xxx
GROUP BY name,date_trunc('minute',timestamp)
ORDER BY timestamp

You can provide various resolutions like 'minute','hour','day' etc... to date_trunc.

You mean JavaScript? Just output it like anything else in the page:

<script type="text/javascript">
  <?php echo "alert('message');"; ?>
</script>

If want PHP to generate a custom message for the alert dialog, then basically you want to write your JavaScript as usual in the HTML, but insert PHP echo statements in the middle of your JavaScript where you want the messages, like:

<script type="text/javascript">
  alert('<?php echo $custom_message; ?>');
</script>

Or you could even do something like this:

<script type="text/javascript">
  var alertMsg = '<?php echo $custom_message; ?>';
  alert(alertMsg);
</script>

Basically, think about where in your JavaScript you want PHP to generate dynamic output and just put an echo statement there.

Strtr replaces single characters instead of strings, so it's a good solution for this example. Supposedly strtr is faster than str_replace (but for this use case they're both immeasurably fast).

echo strtr('Alex Newton',' ','_');
//outputs: Alex_Newton

Some of the time savers:

1. Alt + Enter : show intention actions (like Eclipse quick fix)
2. Ctrl + Alt + V : introduce variable (never type the left hand side of an assignment again)
3. Ctrl + Shift + Space : smart completion ( even two levels down since IntelliJ 8 )
4. Ctrl + W : select succesively increasing code blocks. Kind of obvious but a real time saver!

The Canoo blog contains some (+8) articles on some more advanced IntelliJ keyboard shortcuts.

The Key Promoter and Shortcut keys list plugins are really helpful for (constantly) learning new IntelliJ keyboard shortcuts.

Your method looks like this:

public static bool HasProperty(this object obj, string propertyName)
{
    return obj.GetType().GetProperty(propertyName) != null;
}

This adds an extension onto object - the base class of everything. When you call this extension you're passing it a Type:

var res = typeof(MyClass).HasProperty("Label");

Your method expects an instance of a class, not a Type. Otherwise you're essentially doing

typeof(MyClass) - this gives an instanceof `System.Type`. 

Then

type.GetType() - this gives `System.Type`
Getproperty('xxx') - whatever you provide as xxx is unlikely to be on `System.Type`

As @PeterRitchie correctly points out, at this point your code is looking for property Label on System.Type. That property does not exist.

The solution is either

a) Provide an instance of MyClass to the extension:

var myInstance = new MyClass()
myInstance.HasProperty("Label")

b) Put the extension on System.Type

public static bool HasProperty(this Type obj, string propertyName)
{
    return obj.GetProperty(propertyName) != null;
}

and

typeof(MyClass).HasProperty("Label");

Use SweetAlert's html setting.

You can set output html direct to this option:

var hh = "<b>test</b>";
swal({
    title: "" + txt + "", 
    html: "Testno  sporocilo za objekt " + hh + "",  
    confirmButtonText: "V redu", 
    allowOutsideClick: "true" 
});

Or

swal({
    title: "" + txt + "", 
    html: "Testno  sporocilo za objekt <b>teste</b>",  
    confirmButtonText: "V redu", 
    allowOutsideClick: "true" 
});

In case someone else finds this topic while using localhost in the file URIs - Internet Explorer acts completely different if the host name is localhost or 127.0.0.1 - if you use the actual hostname, it works fine (from trusted sites/intranet zone).

Another big difference between IE and FF - IE is fine with uris like file://server/share/file.txt but FF requires additional slashes file:////server/share/file.txt.

In Eclipse, you don't need to change JAVA_HOME, you just need to change the run configuration for Maven to something above 1.6 (even if your project is on Java 6, Maven shouldn't be). Right-click the project, choose Maven Build or Run As > Run Configurations and set the correct JDK version.

As others have stated there is no standard so you should choose one yourself. Here are a couple of things to consider when doing so:

1. If you are using JavaScript to consume JSON then using the same naming convention for properties in both will provide visual consistency and possibly some opportunities for cleaner code re-use.

2. A small reason to avoid kebab-case is that the hyphens may clash visually with - characters that appear in values.

   {
     "bank-balance": -10

DDD(domain driven design) is a useful concept for analyse of requirements of a project and handling the complexity of these requirements.Before that people were analysing these requirements with considering the relationships between classes and tables and in fact their design were based on database tables relationships it is not old but it has some problems:

• In big projects with complex requirements it is not useful although this is a great way of design for small projects.

• when you are dealing with none technical persons that they don,t have technical concept, this conflict may cause some huge problems in our project.

So DDD handle the first problem with considering the main project as a Domain and splitting each part of this project to small pieces which we are famous to Bounded Context and each of them do not have any influence on other pieces. And the second problem has been solved with a ubiquitous language which is a common language between technical team members and Product owners which are not technical but have enough knowledge about their requirements

Generally the simple definition for Domain is the main project that makes money for the owners and other teams.

You can use implicit transactions for this

SET IMPLICIT_TRANSACTIONS ON

update Staff set staff_Name='jas' where staff_id=7

ROLLBACK

As you request-- You can SET this setting ( SET IMPLICIT_TRANSACTIONS ON) from a stored procedure by setting that stored procedure as the start up procedure.

But SET IMPLICIT TRANSACTION ON command is connection specific. So any connection other than the one which running the start up stored procedure will not benefit from the setting you set.

In my case, I selected wrong RegionEndpoint. After selecting the correct RegionEndpoint, it started working :)

If it is a pandas data frame you could do:

Sending the data

csv_data.to_sql=(con=mydb, name='<the name of your table>',
  if_exists='replace', flavor='mysql')

to avoid the use of the for.

I would use:

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

    super.touchesBegan(touches, withEvent: event)
    let touch : UITouch = touches.anyObject() as UITouch

    if let touchView = touch.view as? UIPickerView
    {

    }
}

Why reinvent the wheel? RandomStringUtils from Apache Commons has functions to which you can specify the character set from which characters are generated. You can take what you need to your app:

http://kickjava.com/src/org/apache/commons/lang/RandomStringUtils.java.htm

Spent a lot of time trying to do this in a simple way. After looking at FOR loop carefully, I realized I can do this with just one line of code:

FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I

Example:

@ECHO OFF
SET Quoted="Test string"

FOR /F "delims=" %%I IN (%Quoted%) DO SET Unquoted=%%I

ECHO %Quoted%
ECHO %Unquoted%

Output:

"Test string"
Test string

You don't seem to have the stopwords corpus on your computer.

You need to start the NLTK Downloader and download all the data you need.

Open a Python console and do the following:

>>> import nltk
>>> nltk.download()
showing info http://nltk.github.com/nltk_data/

In the GUI window that opens simply press the 'Download' button to download all corpora or go to the 'Corpora' tab and only download the ones you need/want.

Try to surround the path with quotes, and remove the spaces

export PYTHONPATH="/home/user/my_project":$PYTHONPATH

And don't forget to preserve previous content suffixing by :$PYTHONPATH (which is the value of the variable)

Execute the following command to check everything is configured correctly:

echo $PYTHONPATH

Table or record locking is available in Access during data writes. You can control the Default record locking through Tools | Options | Advanced tab:

1. No Locks
2. All Records
3. Edited Record

You can set this on a form's Record Locks or in your DAO/ADO code for specific needs.

Transactions shouldn't be a problem if you use them correctly.

Best practice: Separate your tables from All your other code. Give each user their own copy of the code file and then share the data file on a network server. Work on a 'test' copy of the code (and a link to a test data file) and then update user's individual code files separately. If you need to make data file changes (add tables, columns, etc), you will have to have all users get out of the application to make the changes.

See other answers for Oracle comparison.

For those of you who hasn't seen one valid argument against use of Thread.Sleep in SCENARIO 2, there really is one - application exit be held up by the while loop (SCENARIO 1/3 is just plain stupid so not worthy of more mentioning)

Many who pretend to be in-the-know, screaming Thread.Sleep is evil failed to mentioned a single valid reason for those of us who demanded a practical reason not to use it - but here it is, thanks to Pete - Thread.Sleep is Evil (can be easily avoided with a timer/handler)

    static void Main(string[] args)
    {
        Thread t = new Thread(new ThreadStart(ThreadFunc));
        t.Start();

        Console.WriteLine("Hit any key to exit.");
        Console.ReadLine();

        Console.WriteLine("App exiting");
        return;
    }

    static void ThreadFunc()
    {
        int i=0;
        try
        {
            while (true)
            {
                Console.WriteLine(Thread.CurrentThread.ThreadState.ToString() + " " + i);

                Thread.Sleep(1000 * 10);
                i++;
            }
        }
        finally
        {
            Console.WriteLine("Exiting while loop");
        }
        return;
    }

Unfortunately while I thought these answers may have worked for me, I struggled with a solution, as I'm using tables inside responsive tables - where the overflow-x is played with.

So, with that in mind, have a look at this link for a cleaner way, which doesn't have the weird width overflow issues. It worked for me in the end and was very easy to implement.

You can use: interface{}..(type) as in this playground

package main
import "fmt"
func main(){
    types := []interface{} {"a",6,6.0,true}
    for _,v := range types{
        fmt.Printf("%T\n",v)
        switch v.(type) {
        case int:
           fmt.Printf("Twice %v is %v\n", v, v.(int) * 2)
        case string:
           fmt.Printf("%q is %v bytes long\n", v, len(v.(string)))
       default:
          fmt.Printf("I don't know about type %T!\n", v)
      }
    }
}

No need for mysqladmin:

just use mysql command line

mysql -u [username] -p[password] -e 'drop database db-name;'

This will send the drop command although I wouldn't pass the password this way as it'll be exposed to other users of the system via ps aux

You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:

How to disable Ctrl C/V using javascript for both internet explorer and firefox browsers

A more advanced aproach:

How to detect Ctrl+V, Ctrl+C using JavaScript?

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.

There are also separate Time() and Date() functions.

You use something like

from flask import send_file

@app.route('/get_image')
def get_image():
    if request.args.get('type') == '1':
       filename = 'ok.gif'
    else:
       filename = 'error.gif'
    return send_file(filename, mimetype='image/gif')

to send back ok.gif or error.gif, depending on the type query parameter. See the documentation for the send_file function and the request object for more information.

mod = a % b

This stores the result of a mod b in the variable mod.

And you are right, 15 mod 4 is 3, which is exactly what python returns:

>>> 15 % 4
3

a %= b is also valid.

Got this error on eclipse IDE version 4.10, Spring boot 2.2.0.M4, changed the Spring boot version to 2.2.0.M2 (after many other solutions recommended and it solved the error). Maybe something missing or broken in the latest version of Spring boot starter project module maven POM.

What is SQL JOIN ?

SQL JOIN is a method to retrieve data from two or more database tables.

What are the different SQL JOINs ?

There are a total of five JOINs. They are :

  1. JOIN or INNER JOIN
  2. OUTER JOIN

     2.1 LEFT OUTER JOIN or LEFT JOIN
     2.2 RIGHT OUTER JOIN or RIGHT JOIN
     2.3 FULL OUTER JOIN or FULL JOIN

  3. NATURAL JOIN
  4. CROSS JOIN
  5. SELF JOIN

1. JOIN or INNER JOIN :

In this kind of a JOIN, we get all records that match the condition in both tables, and records in both tables that do not match are not reported.

In other words, INNER JOIN is based on the single fact that: ONLY the matching entries in BOTH the tables SHOULD be listed.

Note that a JOIN without any other JOIN keywords (like INNER, OUTER, LEFT, etc) is an INNER JOIN. In other words, JOIN is a Syntactic sugar for INNER JOIN (see: Difference between JOIN and INNER JOIN).

2. OUTER JOIN :

OUTER JOIN retrieves

Either, the matched rows from one table and all rows in the other table Or, all rows in all tables (it doesn't matter whether or not there is a match).

There are three kinds of Outer Join :

2.1 LEFT OUTER JOIN or LEFT JOIN

This join returns all the rows from the left table in conjunction with the matching rows from the right table. If there are no columns matching in the right table, it returns NULL values.

2.2 RIGHT OUTER JOIN or RIGHT JOIN

This JOIN returns all the rows from the right table in conjunction with the matching rows from the left table. If there are no columns matching in the left table, it returns NULL values.

2.3 FULL OUTER JOIN or FULL JOIN

This JOIN combines LEFT OUTER JOIN and RIGHT OUTER JOIN. It returns rows from either table when the conditions are met and returns NULL value when there is no match.

In other words, OUTER JOIN is based on the fact that: ONLY the matching entries in ONE OF the tables (RIGHT or LEFT) or BOTH of the tables(FULL) SHOULD be listed.

Note that `OUTER JOIN` is a loosened form of `INNER JOIN`.

3. NATURAL JOIN :

It is based on the two conditions :

1. the JOIN is made on all the columns with the same name for equality.
2. Removes duplicate columns from the result.

This seems to be more of theoretical in nature and as a result (probably) most DBMS don't even bother supporting this.

4. CROSS JOIN :

It is the Cartesian product of the two tables involved. The result of a CROSS JOIN will not make sense in most of the situations. Moreover, we won't need this at all (or needs the least, to be precise).

5. SELF JOIN :

It is not a different form of JOIN, rather it is a JOIN (INNER, OUTER, etc) of a table to itself.

JOINs based on Operators

Depending on the operator used for a JOIN clause, there can be two types of JOINs. They are

1. Equi JOIN
2. Theta JOIN

1. Equi JOIN :

For whatever JOIN type (INNER, OUTER, etc), if we use ONLY the equality operator (=), then we say that the JOIN is an EQUI JOIN.

2. Theta JOIN :

This is same as EQUI JOIN but it allows all other operators like >, <, >= etc.

Many consider both EQUI JOIN and Theta JOIN similar to INNER, OUTER etc JOINs. But I strongly believe that its a mistake and makes the ideas vague. Because INNER JOIN, OUTER JOIN etc are all connected with the tables and their data whereas EQUI JOIN and THETA JOIN are only connected with the operators we use in the former.

Again, there are many who consider NATURAL JOIN as some sort of "peculiar" EQUI JOIN. In fact, it is true, because of the first condition I mentioned for NATURAL JOIN. However, we don't have to restrict that simply to NATURAL JOINs alone. INNER JOINs, OUTER JOINs etc could be an EQUI JOIN too.

Do you do any more fetches? You should show those as well. You're only showing us half the code.

It should look like:

FETCH NEXT FROM @Outer INTO ...
WHILE @@FETCH_STATUS = 0
BEGIN
  DECLARE @Inner...
  OPEN @Inner
  FETCH NEXT FROM @Inner INTO ...
  WHILE @@FETCH_STATUS = 0
  BEGIN
  ...
    FETCH NEXT FROM @Inner INTO ...
  END
  CLOSE @Inner
  DEALLOCATE @Inner
  FETCH NEXT FROM @Outer INTO ...
END
CLOSE @Outer
DEALLOCATE @Outer

Also, make sure you do not name the cursors the same... and any code (check your triggers) that gets called does not use a cursor that is named the same. I've seen odd behavior from people using 'theCursor' in multiple layers of the stack.

The apache benchmark tool is very basic, and while it will give you a solid idea of some performance, it is a bad idea to only depend on it if you plan to have your site exposed to serious stress in production.

Having said that, here's the most common and simplest parameters:

-c: ("Concurrency"). Indicates how many clients (people/users) will be hitting the site at the same time. While ab runs, there will be -c clients hitting the site. This is what actually decides the amount of stress your site will suffer during the benchmark.

-n: Indicates how many requests are going to be made. This just decides the length of the benchmark. A high -n value with a -c value that your server can support is a good idea to ensure that things don't break under sustained stress: it's not the same to support stress for 5 seconds than for 5 hours.

-k: This does the "KeepAlive" funcionality browsers do by nature. You don't need to pass a value for -k as it it "boolean" (meaning: it indicates that you desire for your test to use the Keep Alive header from HTTP and sustain the connection). Since browsers do this and you're likely to want to simulate the stress and flow that your site will have from browsers, it is recommended you do a benchmark with this.

The final argument is simply the host. By default it will hit http:// protocol if you don't specify it.

ab -k -c 350 -n 20000 example.com/

By issuing the command above, you will be hitting http://example.com/ with 350 simultaneous connections until 20 thousand requests are met. It will be done using the keep alive header.

After the process finishes the 20 thousand requests, you will receive feedback on stats. This will tell you how well the site performed under the stress you put it when using the parameters above.

For finding out how many people the site can handle at the same time, just see if the response times (means, min and max response times, failed requests, etc) are numbers your site can accept (different sites might desire different speeds). You can run the tool with different -c values until you hit the spot where you say "If I increase it, it starts to get failed requests and it breaks".

Depending on your website, you will expect an average number of requests per minute. This varies so much, you won't be able to simulate this with ab. However, think about it this way: If your average user will be hitting 5 requests per minute and the average response time that you find valid is 2 seconds, that means that 10 seconds out of a minute 1 user will be on requests, meaning only 1/6 of the time it will be hitting the site. This also means that if you have 6 users hitting the site with ab simultaneously, you are likely to have 36 users in simulation, even though your concurrency level (-c) is only 6.

This depends on the behavior you expect from your users using the site, but you can get it from "I expect my user to hit X requests per minute and I consider an average response time valid if it is 2 seconds". Then just modify your -c level until you are hitting 2 seconds of average response time (but make sure the max response time and stddev is still valid) and see how big you can make -c.

I hope I explained this clear :) Good luck

Here is my solution in Enterprise 1.11 (should work in CE 1.6):

    $collection->addFieldToFilter('max_item_count',
                    array(
                        array('gteq' => 10),
                        array('null' => true),
                    )
            )
            ->addFieldToFilter('max_item_price',
                    array(
                        array('gteq' => 9.99),
                        array('null' => true),
                    )
            )
            ->addFieldToFilter('max_item_weight',
                    array(
                        array('gteq' => 1.5),
                        array('null' => true),
                    )
            );

Which results in this SQL:

    SELECT `main_table`.*
    FROM `shipping_method_entity` AS `main_table`
    WHERE (((max_item_count >= 10) OR (max_item_count IS NULL)))
      AND (((max_item_price >= 9.99) OR (max_item_price IS NULL)))
      AND (((max_item_weight >= 1.5) OR (max_item_weight IS NULL)))

Take a closer look at the second parameter of json_decode($json, $assoc, $depth) at https://secure.php.net/json_decode

you need object notation

<section [ngClass]="{'class1':condition1, 'class2': condition2, 'class3':condition3}" > 

ref: NgClass

This problem looks similar to one I encountered in a hybrid/embedded systems course, but that was related to detecting faults when the input from a sensor is noisy. We used a Kalman filter to estimate/predict the hidden state of the system, then used statistical analysis to determine the likelihood that a fault had occurred. We were working with linear systems, but nonlinear variants exist. I remember the approach being surprisingly adaptive, but it required a model of the dynamics of the system.

I improved one of the answers a bit to make it work with different keyboards & different textviews/fields on one page:

Add observers:

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillChange(notification:)), name: UIResponder.keyboardWillChangeFrameNotification, object: nil)

    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide), name: UIResponder.keyboardWillHideNotification, object: nil)
}

func keyboardWillHide() {
    self.view.frame.origin.y = 0
}

func keyboardWillChange(notification: NSNotification) {

    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        if YOURTEXTVIEW.isFirstResponder {
            self.view.frame.origin.y = -keyboardSize.height
        }
    }
}

Remove observers:

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillChangeFrameNotification, object: nil)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
}

Not so graceful, but the very much simple in implementation solution - using global variable.

In the "first" file:

window.myApp = angular.module("myApp", [])
....

in the "second" , "third", etc:

myApp.controller('MyController', function($scope) {
    .... 
    }); 

Content that is floating does not influence the height of its container. The element contains no content that isn't floating (so nothing stops the height of the container being 0, as if it were empty).

Setting overflow: hidden on the container will avoid that by establishing a new block formatting context. See methods for containing floats for other techniques and containing floats for an explanation about why CSS was designed this way.

Use the following. It helped me.

document.getElementById('image_1').offsetTop

See also Get Styles.

To simplify these answers, and increase performance when downloading a large file, the below may work a bit more efficiently.

import requests
from contextlib import closing
import csv

url = "http://download-and-process-csv-efficiently/python.csv"

with closing(requests.get(url, stream=True)) as r:
    reader = csv.reader(r.iter_lines(), delimiter=',', quotechar='"')
    for row in reader:
        print row   

By setting stream=True in the GET request, when we pass r.iter_lines() to csv.reader(), we are passing a generator to csv.reader(). By doing so, we enable csv.reader() to lazily iterate over each line in the response with for row in reader.

This avoids loading the entire file into memory before we start processing it, drastically reducing memory overhead for large files.

In case you are using WPF and Xceed's TimePicker (which seems to be using DateTime?) as a timespan picker -as I do right now- you can get the total milliseconds (or a TimeSpan) out of it like so:

var milliseconds = DateTimeToTimeSpan(timePicker.Value).TotalMilliseconds;

    TimeSpan DateTimeToTimeSpan(DateTime? ts)
    {
        if (!ts.HasValue) return TimeSpan.Zero;
        else return new TimeSpan(0, ts.Value.Hour, ts.Value.Minute, ts.Value.Second, ts.Value.Millisecond);
    }

XAML :

<Xceed:TimePicker x:Name="timePicker" Format="Custom" FormatString="H'h 'm'm 's's'" />

If not, I guess you could just adjust my DateTimeToTimeSpan() so that it also takes 'days' into account or do sth like dateTime.Substract(DateTime.MinValue).TotalMilliseconds.

You can also use unlist(), which is often useful for handling lists:

> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))

> mylist
$A
[1] 1 2 3

$B
[1] 4 5 6

$C
[1] 7 8 9

> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3 
 1  2  3  4  5  6  7  8  9 

> length(unlist(mylist))
[1] 9

unlist() is a simple way of executing other functions on lists as well, such as:

> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument

> sum(unlist(mylist))
[1] 45

OO Abstraction occurs during class level design, with the objective of hiding the implementation complexity of how the the features offered by an API / design / system were implemented, in a sense simplifying the 'interface' to access the underlying implementation.

The process of abstraction can be repeated at increasingly 'higher' levels (layers) of classes, which enables large systems to be built without increasing the complexity of code and understanding at each layer.

For example, a Java developer can make use of the high level features of FileInputStream without concern for how it works (i.e. file handles, file system security checks, memory allocation and buffering will be managed internally, and are hidden from consumers). This allows the implementation of FileInputStream to be changed, and as long as the API (interface) to FileInputStream remains consistent, code built against previous versions will still work.

Similarly, when designing your own classes, you will want to hide internal implementation details from others as far as possible.

In the Booch definition¹, OO Encapsulation is achieved through Information Hiding, and specifically around hiding internal data (fields / members representing the state) owned by a class instance, by enforcing access to the internal data in a controlled manner, and preventing direct, external change to these fields, as well as hiding any internal implementation methods of the class (e.g. by making them private).

For example, the fields of a class can be made private by default, and only if external access to these was required, would a get() and/or set() (or Property) be exposed from the class. (In modern day OO languages, fields can be marked as readonly / final / immutable which further restricts change, even within the class).

Example where NO information hiding has been applied (Bad Practice):

class Foo {
   // BAD - NOT Encapsulated - code external to the class can change this field directly
   // Class Foo has no control over the range of values which could be set.
   public int notEncapsulated;
}

Example where field encapsulation has been applied:

class Bar {
   // Improvement - access restricted only to this class
   private int encapsulatedPercentageField;

   // The state of Bar (and its fields) can now be changed in a controlled manner
   public void setEncapsulatedField(int percentageValue) {
      if (percentageValue >= 0 && percentageValue <= 100) {
          encapsulatedPercentageField = percentageValue;
      }
      // else throw ... out of range
   }
}

Example of immutable / constructor-only initialization of a field:

class Baz {
   private final int immutableField;

   public void Baz(int onlyValue) {
      // ... As above, can also check that onlyValue is valid
      immutableField = onlyValue;
   }
   // Further change of `immutableField` outside of the constructor is NOT permitted, even within the same class 
}

Re : Abstraction vs Abstract Class

Abstract classes are classes which promote reuse of commonality between classes, but which themselves cannot directly be instantiated with new() - abstract classes must be subclassed, and only concrete (non abstract) subclasses may be instantiated. Possibly one source of confusion between Abstraction and an abstract class was that in the early days of OO, inheritance was more heavily used to achieve code reuse (e.g. with associated abstract base classes). Nowadays, composition is generally favoured over inheritance, and there are more tools available to achieve abstraction, such as through Interfaces, events / delegates / functions, traits / mixins etc.

Re : Encapsulation vs Information Hiding

The meaning of encapsulation appears to have evolved over time, and in recent times, encapsulation can commonly also used in a more general sense when determining which methods, fields, properties, events etc to bundle into a class.

Quoting Wikipedia:

In the more concrete setting of an object-oriented programming language, the notion is used to mean either an information hiding mechanism, a bundling mechanism, or the combination of the two.

For example, in the statement

I've encapsulated the data access code into its own class

.. the interpretation of encapsulation is roughly equivalent to the Separation of Concerns or the Single Responsibility Principal (the "S" in SOLID), and could arguably be used as a synonym for refactoring.

^{[1] _{Once you've seen Booch's encapsulation cat picture you'll never be able to forget encapsulation - p46 of Object Oriented Analysis and Design with Applications, 2nd Ed}}

Yes, you can configure the Spring servlet context xml file to define your beans (i.e., classes), so that it can do the automatic injection for you. However, do note, that you have to do other configurations to have Spring up and running and the best way to do that, is to follow a tutorial ground up.

Once you have your Spring configured probably, you can do the following in your Spring servlet context xml file for Example 1 above to work (please replace the package name of com.movies to what the true package name is and if this is a 3rd party class, then be sure that the appropriate jar file is on the classpath) :

<beans:bean id="movieFinder" class="com.movies.MovieFinder" />

or if the MovieFinder class has a constructor with a primitive value, then you could something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg value="100" />
</beans:bean>

or if the MovieFinder class has a constructor expecting another class, then you could do something like this,

<beans:bean id="movieFinder" class="com.movies.MovieFinder" >
    <beans:constructor-arg ref="otherBeanRef" />
</beans:bean>

...where 'otherBeanRef' is another bean that has a reference to the expected class.

Complicated way but works:

$num = '125.0100';
$index = $num[strlen($num)-1];
$i = strlen($num)-1;
while($index == '0') {
   if ($num[$i] == '0') {
     $num[$i] = '';
     $i--;
   }

   $index = $num[$i];
}

//remove dot if no numbers exist after dot
$explode = explode('.', $num);
if (isset($explode[1]) && intval($explode[1]) <= 0) {
   $num = intval($explode[0]);
}

echo $num; //125.01

the solutions above are the optimal way but in case you want to have your own you could use this. What this algorithm does it starts at the end of string and checks if its 0, if it is it sets to empty string and then goes to the next character from back untill the last character is > 0

Another possible parameter expansion:

for f in fgh*; do mv -- "$f" "jkl${f:3}"; done

in my own case in django 1.10.1 running on python2.7.11, I was trying to start the server using django-admin runserver instead of manage.py runserver in my project directory.

or just study /etc/groups (ok this does probably not work if it uses pam with ldap)

• Upcasting is an operation that creates a base class reference from a subclass reference. (subclass -> superclass) (i.e. Manager -> Employee)
• Downcasting is an operation that creates a subclass reference from a base class reference. (superclass -> subclass) (i.e. Employee -> Manager)

In your case

Employee emp = (Employee)mgr; //mgr is Manager

you are doing an upcasting.

An upcast always succeeds unlike a downcast that requires an explicit cast because it can potentially fail at runtime.(InvalidCastException).

C# offers two operators to avoid this exception to be thrown:

Starting from:

Employee e = new Employee();

First:

Manager m = e as Manager; // if downcast fails m is null; no exception thrown

Second:

if (e is Manager){...} // the predicate is false if the downcast is not possible 

Warning: When you do an upcast you can only access to the superclass' methods, properties etc...

In simple:

Git - is local repository.

GitHub - is central repository.

Hope below image will help to understand:

The exact answer to the question is: yes, you can use an arbitrary value for the boundary parameter, given it does not exceed 70 bytes in length and consists only of 7-bit US-ASCII (printable) characters.

If you are using one of multipart/* content types, you are actually required to specify the boundary parameter in the Content-Type header, otherwise the server (in the case of an HTTP request) will not be able to parse the payload.

You probably also want to set the charset parameter to UTF-8 in your Content-Type header, unless you can be absolutely sure that only US-ASCII charset will be used in the payload data.

A few relevant excerpts from the RFC2046:

• 4.1.2. Charset Parameter:

  Unlike some other parameter values, the values of the charset parameter are NOT case sensitive. The default character set, which must be assumed in the absence of a charset parameter, is US-ASCII.

• 5.1. Multipart Media Type

  As stated in the definition of the Content-Transfer-Encoding field [RFC 2045], no encoding other than "7bit", "8bit", or "binary" is permitted for entities of type "multipart". The "multipart" boundary delimiters and header fields are always represented as 7bit US-ASCII in any case (though the header fields may encode non-US-ASCII header text as per RFC 2047) and data within the body parts can be encoded on a part-by-part basis, with Content-Transfer-Encoding fields for each appropriate body part.

  The Content-Type field for multipart entities requires one parameter, "boundary". The boundary delimiter line is then defined as a line consisting entirely of two hyphen characters ("-", decimal value 45) followed by the boundary parameter value from the Content-Type header field, optional linear whitespace, and a terminating CRLF.

  Boundary delimiters must not appear within the encapsulated material, and must be no longer than 70 characters, not counting the two leading hyphens.

  The boundary delimiter line following the last body part is a distinguished delimiter that indicates that no further body parts will follow. Such a delimiter line is identical to the previous delimiter lines, with the addition of two more hyphens after the boundary parameter value.

Here is an example using an arbitrary boundary:

Content-Type: multipart/form-data; charset=utf-8; boundary="another cool boundary"

--another cool boundary
Content-Disposition: form-data; name="foo"

bar
--another cool boundary
Content-Disposition: form-data; name="baz"

quux
--another cool boundary--

For me the problem was that I was using different versions of Python in the same Eclipse project. My setup was not consistent with the Project Properties and the Run Configuration Python versions.

In Project > Properties > PyDev, I had the Interpreter set to Python2.7.11.

In Run Configurations > Interpreter, I was using the Default Interpreter. Changing it to Python 2.7.11 fixed the problem.

this example, I am assuming that all your image files begin with "IMG" and you want to replace "IMG" with "VACATION"

solution : first identified all jpg files and then replace keyword

find . -name '*jpg' -exec bash -c 'echo mv $0 ${0/IMG/VACATION}' {} \; 

If you are fine using a graphical tool this works very well:

gitk <file>

gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!

Have a look at agiletoolkit.org as this has a simple to use CRUD which supports 2,4,6,7,9,10 and 12 out of the box (uses Ajax to defender the grid when adding,deleting data and it integrates with jquery.

I would post some examples but on an iPad at the moment.

What you want is called an associative array. In python these are called dictionaries.

Dictionaries are sometimes found in other languages as “associative memories” or “associative arrays”. Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys.

myDict = {}
myDict["john"] = "johns value"
myDict["jeff"] = "jeffs value"

Alternative way to create the above dict:

myDict = {"john": "johns value", "jeff": "jeffs value"}

Accessing values:

print(myDict["jeff"]) # => "jeffs value"

Getting the keys (in Python v2):

print(myDict.keys()) # => ["john", "jeff"]

In Python 3, you'll get a dict_keys, which is a view and a bit more efficient (see views docs and PEP 3106 for details).

print(myDict.keys()) # => dict_keys(['john', 'jeff']) 

If you want to learn about python dictionary internals, I recommend this ~25 min video presentation: https://www.youtube.com/watch?v=C4Kc8xzcA68. It's called the "The Mighty Dictionary".

Please see https://github.com/joshua-gould/canvas2pdf. This library creates a PDF representation of your canvas element, unlike the other proposed solutions which embed an image in a PDF document.

//Create a new PDF canvas context.
var ctx = new canvas2pdf.Context(blobStream());

//draw your canvas like you would normally
ctx.fillStyle='yellow';
ctx.fillRect(100,100,100,100);
// more canvas drawing, etc...

//convert your PDF to a Blob and save to file
ctx.stream.on('finish', function () {
    var blob = ctx.stream.toBlob('application/pdf');
    saveAs(blob, 'example.pdf', true);
});
ctx.end();
