In the past I have created my XML Schema, then used a tool to generate C# classes which will serialize to that schema. The XML Schema Definition Tool is one example

This is not possible as of May 2017, because Postman only works with HTTP methods such as POST, GET, PUT, DELETE.

P/S: There is a request for this if you want to upvote: github.com/postmanlabs/postman-app-support/issues/4009

Try this:

cc=is.na(DF$y)
m=which(cc==c("TRUE"))
DF=DF[-m,]

There is a necessary step which is not detailed:

ADB must be running (it is not because it is installed that it will run to establish the connection)

For an unknown reason to open "developer tools" on chrome (canary) will not necessarily launch the run of ADB with good parameters. Then you will not see on the smartphone the question "Confirm remote connection with 'your pc address' " while on PC you can see on the connection panel "pending unknown connection". Then necessarily if this not happens the connection will not be established. Note that some other tools launches ADB but what important is to launch ADB and establish the connection.

When you run ">ADB connect 'IPofYourSmartphone port' " or ADB is run by a soft to get right connection, ADB sends the request which show the panel confirmation on your Smartphone

This is too valid for USB or Wifi connection. If you use on android a tool like "ADB wireless by Henry" you will get a full guide to get a wifi debugging remote connection.

I found another way to handle it.

Map obj=new HashMap();    
obj.put("name","sonoo");    
obj.put("age",new Integer(27));    
obj.put("salary",new Double(600000));   
String jsonText = JSONValue.toJSONString(obj);  
System.out.print(jsonText);

Hope this helps.

Thanks.

I normally use the history object for this. It also does not reload the page.

Example:

history.pushState({}, '', 
                `/pagepath/path?query=${this.myQueryParam}`);

You could do:

svn revert -R .

This will not delete any new file not under version control. But you can easily write a shell script to do that like:

for file in `svn status|grep "^ *?"|sed -e 's/^ *? *//'`; do rm $file ; done

Sure:

public HttpResponseMessage Post()
{
    // ... do the job

    // now redirect
    var response = Request.CreateResponse(HttpStatusCode.Moved);
    response.Headers.Location = new Uri("http://www.abcmvc.com");
    return response;
}

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

I know my answer is late, but IMO this is the easiest way to toggle a Button 'enable' and button 'disable'

function toggleButtonState(button){

  //If button is enabled, -> Disable
  if (button.disabled === false) {
    button.disabled = true;

  //If button is disabled, -> Enable
  } else if (button.disabled === true) {
    button.disabled = false;
  }
}

I am in the situation where I have to controls that spawn dialogs, each of them need to have a ckeditor embedded inside these dialogs. And it just so happens the text areas share the same id. (normally this is very bad practice, but I have 2 jqGrids, one of assigned items and another of unassigned items.) They share almost identical configuration. Thus, I am using common code to configure both.

So, when I load a dialog, for adding rows, or for editing them, from either jqGrid; I must remove all instances of CKEDITOR in all textareas.

$('textarea').each(function()
{
    try 
    {
        if(CKEDITOR.instances[$(this)[0].id] != null)
        {
            CKEDITOR.instances[$(this)[0].id].destroy();
        }
    }
    catch(e)
    {

    }
});

This will loop over all textareas, and if there is a CKEDITOR instance, then destroy it.

Alternatively if you use pure jQuery:

$('textarea').each(function()
{
    try 
    {
        $(this).ckeditorGet().destroy();
    }
    catch(e)
    {

    }
});

If you want run formula on worksheet by function that execute SQL statement then use Add-in A-Tools

Example, function BS_SQL("SELECT ..."):

Code check:

This is offtopic here but the people over at CodeReview are more than happy to help you.

I strongly suggest you to do so, there are several things that need attention in your code. Likewise I suggest that you do start reading tutorials since there is really no good reason not to do so.

Lists:

As you said yourself: you need a list of items. The way it is now you only store a reference to one item. Lucky there is exactly that to hold a group of related objects: a List.

Lists are very straightforward to use but take a look at the related documentation anyway.

A very simple example to keep multiple bikes in a list:

List<Motorbike> bikes = new List<Motorbike>();

bikes.add(new Bike { make = "Honda", color = "brown" });
bikes.add(new Bike { make = "Vroom", color = "red" });

And to iterate over the list you can use the foreach statement:

foreach(var bike in bikes) {
     Console.WriteLine(bike.make);
}

You can use getContent() method on Request object.

$request->getContent() //json as a string.

Simple Solution (2020) is as follows :-

1. npm install --save jquery popper.js
2. npm install --save bootstrap
3. npm install --save style-loader css-loader
4. update webpack.config.js, you've to tell webpack how to handle the bootstrap CSS files hence you've to add some rules as shown :-

5. Add some imports in the entry point of your React Application (usually it's index.js), place them at the top make sure you don't change the order.

import "bootstrap/dist/css/bootstrap.min.css";

import $ from "jquery";

import Popper from "popper.js";

import "bootstrap/dist/js/bootstrap.bundle.min";

6. These steps should help you out, please comment if there's some problem.

If multiple clock are generated with different frequencies, then clock generation can be simplified if a procedure is called as concurrent procedure call. The time resolution issue, mentioned by Martin Thompson, may be mitigated a little by using different high and low time in the procedure. The test bench with procedure for clock generation is:

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture sim of tb is

  -- Procedure for clock generation
  procedure clk_gen(signal clk : out std_logic; constant FREQ : real) is
    constant PERIOD    : time := 1 sec / FREQ;        -- Full period
    constant HIGH_TIME : time := PERIOD / 2;          -- High time
    constant LOW_TIME  : time := PERIOD - HIGH_TIME;  -- Low time; always >= HIGH_TIME
  begin
    -- Check the arguments
    assert (HIGH_TIME /= 0 fs) report "clk_plain: High time is zero; time resolution to large for frequency" severity FAILURE;
    -- Generate a clock cycle
    loop
      clk <= '1';
      wait for HIGH_TIME;
      clk <= '0';
      wait for LOW_TIME;
    end loop;
  end procedure;

  -- Clock frequency and signal
  signal clk_166 : std_logic;
  signal clk_125 : std_logic;

begin

  -- Clock generation with concurrent procedure call
  clk_gen(clk_166, 166.667E6);  -- 166.667 MHz clock
  clk_gen(clk_125, 125.000E6);  -- 125.000 MHz clock

  -- Time resolution show
  assert FALSE report "Time resolution: " & time'image(time'succ(0 fs)) severity NOTE;

end architecture;

The time resolution is printed on the terminal for information, using the concurrent assert last in the test bench.

If the clk_gen procedure is placed in a separate package, then reuse from test bench to test bench becomes straight forward.

Waveform for clocks are shown in figure below.

An more advanced clock generator can also be created in the procedure, which can adjust the period over time to match the requested frequency despite the limitation by time resolution. This is shown here:

-- Advanced procedure for clock generation, with period adjust to match frequency over time, and run control by signal
procedure clk_gen(signal clk : out std_logic; constant FREQ : real; PHASE : time := 0 fs; signal run : std_logic) is
  constant HIGH_TIME   : time := 0.5 sec / FREQ;  -- High time as fixed value
  variable low_time_v  : time;                    -- Low time calculated per cycle; always >= HIGH_TIME
  variable cycles_v    : real := 0.0;             -- Number of cycles
  variable freq_time_v : time := 0 fs;            -- Time used for generation of cycles
begin
  -- Check the arguments
  assert (HIGH_TIME /= 0 fs) report "clk_gen: High time is zero; time resolution to large for frequency" severity FAILURE;
  -- Initial phase shift
  clk <= '0';
  wait for PHASE;
  -- Generate cycles
  loop
    -- Only high pulse if run is '1' or 'H'
    if (run = '1') or (run = 'H') then
      clk <= run;
    end if;
    wait for HIGH_TIME;
    -- Low part of cycle
    clk <= '0';
    low_time_v := 1 sec * ((cycles_v + 1.0) / FREQ) - freq_time_v - HIGH_TIME;  -- + 1.0 for cycle after current
    wait for low_time_v;
    -- Cycle counter and time passed update
    cycles_v := cycles_v + 1.0;
    freq_time_v := freq_time_v + HIGH_TIME + low_time_v;
  end loop;
end procedure;

Again reuse through a package will be nice.

This will get you your comma seperated values as well as add the fixed notation to the end.

    nStr="1000";
    nStr += '';
    x = nStr.split('.');
    x1 = x[0];
    x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
        x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    commaSeperated = x1 + x2 + ".00";
    alert(commaSeperated);

In case you are getting this in the eclipse IDE, even after setting the parameters --launcher.XXMaxPermSize, -XX:MaxPermSize, etc, still if you are getting the same error, it most likely is that the eclipse is using a buggy version of JRE which would have been installed by some third party applications and set to default. These buggy versions do not pick up the PermSize parameters and so no matter whatever you set, you still keep getting these memory errors. So, in your eclipse.ini add the following parameters:

-vm <path to the right JRE directory>/<name of javaw executable>

Also make sure you set the default JRE in the preferences in the eclipse to the correct version of java.

The error you posted can happen when you're using a clause in the GROUP BY statement without including it in the select.

Example

This one works!

     SELECT t.device,
            SUM(case when transits.direction = 1 then 1 else 0 end) ,
            SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t 
            where t.device in ('A','B') group by t.device

This one not (omitted t.device from the select)

     SELECT 
            SUM(case when transits.direction = 1 then 1 else 0 end) ,
            SUM(case when transits.direction = 0 then 1 else 0 end) from t1 t 
            where t.device in ('A','B') group by t.device

This will produce your error complaining that I'm grouping for something that is not included in the select

Please, provide all the query to get more support.

string[,] Tablero = new string[3,3];

A handy way to achieve this would be:

df.groupby('a').agg({'b':lambda x: list(x)})

Look into writing Custom Aggregations: https://www.kaggle.com/akshaysehgal/how-to-group-by-aggregate-using-py

From DateTime on msdn:

Type: System.DateTime% When this method returns, contains the DateTime value equivalent to the date and time contained in s, if the conversion succeeded, or MinValue if the conversion failed. The conversion fails if the s parameter is null, is an empty string (""), or does not contain a valid string representation of a date and time. This parameter is passed uninitialized.

Use parseexact with the format string "yyyy-dd-MM hh:mm tt" instead.

Either might be fine, but I don't think there is a definite answer.

• If you want to indicate that the value has not been set, comparing with None is better than comparing with "", since "" might be a valid value,
• If you just want a default value, "" is probably better, because its actually a string, and you can call string methods on it. If you went with None, these would lead to exceptions.
• If you wish to indicate to future maintainers that a string is required here, "" can help with that.

Complete side note:

If you have a loop, say:

def myfunc (self, mystr = ""):
    for other in self.strs:
        mystr = self.otherfunc (mystr, other)

then a potential future optimizer would know that str is always a string. If you used None, then it might not be a string until the first iteration, which would require loop unrolling to get the same effects. While this isn't a hypothetical (it comes up a lot in my PHP compiler) you should certainly never write your code to take this into account. I just thought it might be interesting :)

You need JDK for that.

Set JAVA_HOME to point to the JDK.

The dot is not part of the class name. It's only used in CSS/jQuery selector notation. Try this instead:

if ($('#navigation a').hasClass('active')) {
    $(this).parent().addClass('active');
}

If $(this) refers to that anchor, you have to change it to $('#navigation a') as well because the if condition does not have jQuery callback scope.

If the same error occurs in ADT/Eclipse

Add Action Bar Sherlock library in your project.

Now, to remove the "import The import android.support.v7 cannot be resolved" error download a jar file named as android-support-v7-appcompat.jar and add it in your project lib folder.

This will surely removes your both errors.

Improvement to @madprops answer - solution as a django management command:

import MySQLdb
from django.conf import settings

from django.core.management.base import BaseCommand


class Command(BaseCommand):

    def handle(self, *args, **options):
        host = settings.DATABASES['default']['HOST']
        password = settings.DATABASES['default']['PASSWORD']
        user = settings.DATABASES['default']['USER']
        dbname = settings.DATABASES['default']['NAME']

        db = MySQLdb.connect(host=host, user=user, passwd=password, db=dbname)
        cursor = db.cursor()

        cursor.execute("ALTER DATABASE `%s` CHARACTER SET 'utf8' COLLATE 'utf8_unicode_ci'" % dbname)

        sql = "SELECT DISTINCT(table_name) FROM information_schema.columns WHERE table_schema = '%s'" % dbname
        cursor.execute(sql)

        results = cursor.fetchall()
        for row in results:
            print(f'Changing table "{row[0]}"...')
            sql = "ALTER TABLE `%s` convert to character set DEFAULT COLLATE DEFAULT" % (row[0])
            cursor.execute(sql)
        db.close()

Hope this helps anybody but me :)

This may be used in many other scenarios, where you need to copy only a portion of your original string to the destination. Using strncpy() you can copy a limited portion of the original string as opposed by strcpy(). I see the code you have put up comes from publib.boulder.ibm.com.

I'm not sure about HQL, but in JPA you just call the query's setParameter with the parameter and collection.

Query q = entityManager.createQuery("SELECT p FROM Peron p WHERE name IN (:names)");
q.setParameter("names", names);

where names is the collection of names you're searching for

Collection<String> names = new ArrayList<String();
names.add("Joe");
names.add("Jane");
names.add("Bob");

Years ago, when mailing functionality was introduced, so that was utterly text based, as the time passed, need for attachments like image and media (audio,video etc) came into existence. When these attachments are sent over internet (which is basically in the form of binary data), the probability of binary data getting corrupt is high in its raw form. So, to tackle this problem BASE64 came along.

The problem with binary data is that it contains null characters which in some languages like C,C++ represent end of character string so sending binary data in raw form containing NULL bytes will stop a file from being fully read and lead in a corrupt data.

For Example :

In C and C++, this "null" character shows the end of a string. So "HELLO" is stored like this:

H E L L O

72 69 76 76 79 00

The 00 says "stop here".

Now let’s dive into how BASE64 encoding works.

Point to be noted : Length of the string should be in multiple of 3.

Example 1 :

String to be encoded : “ace”, Length=3

1) Convert each character to decimal.

a= 97, c= 99, e= 101

2) Change each decimal to 8-bit binary representation.

97= 01100001, 99= 01100011, 101= 01100101

Combined : 01100001 01100011 01100101

3) Seperate in a group of 6-bit.

011000 010110 001101 100101

4) Calculate binary to decimal

011000= 24, 010110= 22, 001101= 13, 100101= 37

5) Covert decimal characters to base64 using base64 chart.

24= Y, 22= W, 13= N, 37= l

“ace” => “YWNl”

Example 2 :

String to be encoded : “abcd” Length=4, it's not multiple of 3. So to make string length multiple of 3 , we must add 2 bit padding to make length= 6. Padding bit is represented by “=” sign.

Point to be noted : One padding bit equals two zeroes 00 so two padding bit equals four zeroes 0000.

So lets start the process :–

1) Convert each character to decimal.

a= 97, b= 98, c= 99, d= 100

2) Change each decimal to 8-bit binary representation.

97= 01100001, 98= 01100010, 99= 01100011, 100= 01100100

3) Separate in a group of 6-bit.

011000, 010110, 001001, 100011, 011001, 00

so the last 6-bit is not complete so we insert two padding bit which equals four zeroes “0000”.

011000, 010110, 001001, 100011, 011001, 000000 ==

Now, it is equal. Two equals sign at the end show that 4 zeroes were added (helps in decoding).

4) Calculate binary to decimal.

011000= 24, 010110= 22, 001001= 9, 100011= 35, 011001= 25, 000000=0 ==

5) Covert decimal characters to base64 using base64 chart.

24= Y, 22= W, 9= j, 35= j, 25= Z, 0= A ==

“abcd” => “YWJjZA==”

    byte[] bytes = Encoding.UTF8.GetBytes(postData);

chmod 755 /usr/local/bin/redis-cli

Basically in the world of IT certifications, you can call yourself just about anything you want as long as you don't step on the toes of a "real" professional organization. For example, you can be a "Microsoft Certified Solution Engineer" on your business card, but if you write the magic phrase "Professional Engineer" (or P. Eng) you're in legal trouble unless you've got that iron ring. I know there's a similar title for "real" architects, which I can't remember, but as long as you don't mention that you can be a "Cisco Certified Network Architect" or similar.

var str = "I learned to play the Ukulele in Lebanon."
var regex = /le/gi, result, indices = [];
while ( (result = regex.exec(str)) ) {
    indices.push(result.index);
}

UPDATE

I failed to spot in the original question that the search string needs to be a variable. I've written another version to deal with this case that uses indexOf, so you're back to where you started. As pointed out by Wrikken in the comments, to do this for the general case with regular expressions you would need to escape special regex characters, at which point I think the regex solution becomes more of a headache than it's worth.

function getIndicesOf(searchStr, str, caseSensitive) {_x000D_
    var searchStrLen = searchStr.length;_x000D_

This is a bug in pycharm. PyCharm seems to be expecting the referenced module to be included in an __all__ = [] statement.

For proper coding etiquette, should you include the __all__ statement from your modules? ..this is actually the question we hear young Spock answering while he was being tested, to which he responded: "It is morally praiseworthy but not morally obligatory."

To get around it, you can simply disable that (extremely non-critical) (highly useful) inspection globally, or suppress it for the specific function or statement.

To do so:

• put the caret over the erroring text ('choice', from your example above)
• Bring up the intention menu (alt-enter by default, mine is set to alt-backspace)
• hit the right arrow to open the submenu, and select the relevant action

PyCharm has its share of small bugs like this, but in my opinion its benefits far outweigh its drawbacks. If you'd like to try another good IDE, there's also Spyder/Spyderlib.

I know this is quite a bit after you asked your question, but I hope this helps (you, or someone else).

Edited: Originally, I thought that this was specific to checking __all__, but it looks like it's the more general 'Unresolved References' check, which can be very useful. It's probably best to use statement-level disabling of the feature, either by using the menu as mentioned above, or by specifying # noinspection PyUnresolvedReferences on the line preceding the statement.

You can use case in bash to simulate a goto:

#!/bin/bash

case bar in
  foo)
    echo foo
    ;&

  bar)
    echo bar
    ;&

  *)
    echo star
    ;;
esac

produces:

bar
star

throw $e->getMessage();

You try to throw a string

As a sidenote: Exceptions are usually to define exceptional states of the application and not for error messages after validation. Its not an exception, when a user gives you invalid data

I like doing git shortlog -s -n --all. Gives you a "leaderboard" style list of names and number of commits.

The traditional way is to have a Makefile in each of the subdirectories (part1, part2, etc.) allowing you to build them independently. Further, have a Makefile in the root directory of the project which builds everything. The "root" Makefile would look something like the following:

all:
    +$(MAKE) -C part1
    +$(MAKE) -C part2
    +$(MAKE) -C part3

Since each line in a make target is run in its own shell, there is no need to worry about traversing back up the directory tree or to other directories.

I suggest taking a look at the GNU make manual section 5.7; it is very helpful.

Next to the great answer by @pimvdb, and just in case you where wondering, async.js does not offer truly asynchronous functions either. Here is a (very) stripped down version of the library's main method:

function asyncify(func) { // signature: func(array)
    return function (array, callback) {
        var result;
        try {
            result = func.apply(this, array);
        } catch (e) {
            return callback(e);
        }
        /* code ommited in case func returns a promise */
        callback(null, result);
    };
}

So the function protects from errors and gracefully hands it to the callback to handle, but the code is as synchronous as any other JS function.

Your web_window variable must have gone out of scope when you tried to close the window. Add this line into your _openpageview function to test:

setTimeout(function(){web_window.close();},1000);

If you are working in node.js with lusca try also this:

$.ajax({
url: "http://test.com",
type:"post"

Kyril's answer is best considering you need to be able to handle newlines on different machines.

"I'm mostly looking for useful PHP functions, not an algorithm for how to do it. Any suggestions?"

I use these a lot:

• explode() can be used to split a string into an array, given a single delimiter.
• implode() is explode's counterpart, to go from array back to string.

My experience of XmlReader is that it's very easy to accidentally read too much. I know you've said you want to read it as quickly as possible, but have you tried using a DOM model instead? I've found that LINQ to XML makes XML work much much easier.

If your document is particularly huge, you can combine XmlReader and LINQ to XML by creating an XElement from an XmlReader for each of your "outer" elements in a streaming manner: this lets you do most of the conversion work in LINQ to XML, but still only need a small portion of the document in memory at any one time. Here's some sample code (adapted slightly from this blog post):

static IEnumerable<XElement> SimpleStreamAxis(string inputUrl,
                                              string elementName)
{
  using (XmlReader reader = XmlReader.Create(inputUrl))
  {
    reader.MoveToContent();
    while (reader.Read())
    {
      if (reader.NodeType == XmlNodeType.Element)
      {
        if (reader.Name == elementName)
        {
          XElement el = XNode.ReadFrom(reader) as XElement;
          if (el != null)
          {
            yield return el;
          }
        }
      }
    }
  }
}

I've used this to convert the StackOverflow user data (which is enormous) into another format before - it works very well.

EDIT from radarbob, reformatted by Jon - although it's not quite clear which "read too far" problem is being referred to...

This should simplify the nesting and take care of the "a read too far" problem.

using (XmlReader reader = XmlReader.Create(inputUrl))
{
    reader.ReadStartElement("theRootElement");

    while (reader.Name == "TheNodeIWant")
    {
        XElement el = (XElement) XNode.ReadFrom(reader);
    }

    reader.ReadEndElement();
}

This takes care of "a read too far" problem because it implements the classic while loop pattern:

initial read;
(while "we're not at the end") {
    do stuff;
    read;
}

My case: Seeing the same INFO message.

Centos 6.2 x86_64 Tomcat 6.0.24

This fixed the problem for me:

boom!

Simply

$os = array("Mac", "NT", "Irix", "Linux");
if (!in_array("BB", $os)) {
    echo "BB is not found";
}

After adding the cordova-plugin-whitelist, you must tell your application to allow access all the web-page links or specific links, if you want to keep it specific.

You can simply add this to your config.xml, which can be found in your application's root directory:

Recommended in the documentation:

<allow-navigation href="http://example.com/*" />

or:

<allow-navigation href="http://*/*" />

From the plugin's documentation:

Navigation Whitelist

Controls which URLs the WebView itself can be navigated to. Applies to top-level navigations only.

Quirks: on Android it also applies to iframes for non-http(s) schemes.

By default, navigations only to file:// URLs, are allowed. To allow other other URLs, you must add tags to your config.xml:

<!-- Allow links to example.com -->
<allow-navigation href="http://example.com/*" />

<!-- Wildcards are allowed for the protocol, as a prefix
     to the host, or as a suffix to the path -->
<allow-navigation href="*://*.example.com/*" />

<!-- A wildcard can be used to whitelist the entire network,
     over HTTP and HTTPS.
     *NOT RECOMMENDED* -->
<allow-navigation href="*" />

<!-- The above is equivalent to these three declarations -->
<allow-navigation href="http://*/*" />
<allow-navigation href="https://*/*" />
<allow-navigation href="data:*" />

check the name of the database in a file where you established a connection.

Try this:

@echo off
for /f "tokens=*" %%a in (input.txt) do (
  echo line=%%a
)
pause

because of the tokens=* everything is captured into %a

edit: to reply to your comment, you would have to do that this way:

@echo off
for /f "tokens=*" %%a in (input.txt) do call :processline %%a

pause
goto :eof

:processline
echo line=%*

goto :eof

:eof

Because of the spaces, you can't use %1, because that would only contain the part until the first space. And because the line contains quotes, you can also not use :processline "%%a" in combination with %~1. So you need to use %* which gets %1 %2 %3 ..., so the whole line.

$rows = array();
while($r = mysql_fetch_assoc($result)) {
    $r["id"] = intval($r["id"]); 
    $rows[] = $r;
}
print json_encode($rows);  

Mutex is binary semaphore. It must be initialized with 1, so that the First Come First Serve principle is met. This brings us to the other special property of each mutex: the one who did down, must be the one who does up. Ergo we have obtained mutual exclusion over some resource.

Now you could see that a mutex is a special case of general semaphore.

The assert computer statement is analogous to the statement make sure in English.

It's actually working quite good with:

import sys
mods = [m.__name__ for m in sys.modules.values() if m]

This will create a list with importable module names.

Also try aspnet_regiis -u then aspnet_regiis -i on below path

Now restart the IIS and check

DateTime supports normal comparision operators.

See if this works for you... In this code, I had 3 2-dimensional arrays, called red,green and blue. Each one was of size [width][height], and each element corresponded to a pixel - I hope this makes sense!

FILE *f;
unsigned char *img = NULL;
int filesize = 54 + 3*w*h;  //w is your image width, h is image height, both int

img = (unsigned char *)malloc(3*w*h);
memset(img,0,3*w*h);

for(int i=0; i<w; i++)
{
    for(int j=0; j<h; j++)
    {
        x=i; y=(h-1)-j;
        r = red[i][j]*255;
        g = green[i][j]*255;
        b = blue[i][j]*255;
        if (r > 255) r=255;
        if (g > 255) g=255;
        if (b > 255) b=255;
        img[(x+y*w)*3+2] = (unsigned char)(r);
        img[(x+y*w)*3+1] = (unsigned char)(g);
        img[(x+y*w)*3+0] = (unsigned char)(b);
    }
}

A quick and easy Tidyverse solution to get a NA count for all columns is to use summarise_all() which I think makes a much easier to read solution than using purrr or sapply

library(tidyverse)
# Example data
df <- tibble(col1 = c(1, 2, 3, NA), 
             col2 = c(NA, NA, "a", "b"))

df %>% summarise_all(~ sum(is.na(.)))
#> # A tibble: 1 x 2
#>    col1  col2
#>   <int> <int>
#> 1     1     2

I don't think there's a good "jQuery " way to do this, but if you need efficiency, map one of the arrays by a certain key (one of the unique object fields), and then do comparison by looping through the other array and comparing against the map, or associative array, you just built.

If efficiency is not an issue, just compare every object in A to every object in B. As long as |A| and |B| are small, you should be okay.

document.getElementsByClassName returns an array of elements. so may be you want to target a specific index of them: var comment = document.getElementsByClassName('button')[0]; should get you what you want.

Update #1:

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment() {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Update #2: (with removeEventListener incorporated as well)

var comments = document.getElementsByClassName('button');
var numComments = comments.length;

function showComment(e) {
  var place = document.getElementById('textfield');
  var commentBox = document.createElement('textarea');
  place.appendChild(commentBox);
  for (var i = 0; i < numComments; i++) {
    comments[i].removeEventListener('click', showComment, false);
  }
}

for (var i = 0; i < numComments; i++) {
  comments[i].addEventListener('click', showComment, false);
}

Yes. In Ruby the not equal to operator is:

!=

You can get a full list of ruby operators here: https://www.tutorialspoint.com/ruby/ruby_operators.htm.

simplest options ls :

dict  = {'A':a,'B':b}
df = pd.DataFrame(dict, index = np.arange(1) )

You can directly use time.Unix function of time which converts the unix time stamp to UTC

package main

import (
  "fmt"
  "time"
)


func main() {
    unixTimeUTC:=time.Unix(1405544146, 0) //gives unix time stamp in utc 

    unitTimeInRFC3339 :=unixTimeUTC.Format(time.RFC3339) // converts utc time to RFC3339 format

    fmt.Println("unix time stamp in UTC :--->",unixTimeUTC)
    fmt.Println("unix time stamp in unitTimeInRFC3339 format :->",unitTimeInRFC3339)
}

Output

unix time stamp in UTC :---> 2014-07-16 20:55:46 +0000 UTC
unix time stamp in unitTimeInRFC3339 format :----> 2014-07-16T20:55:46Z

And it's unlikely too -- EOT is a fairly restrictive format that is supported only by IE. Both Safari 3.1 and Firefox 3.1 (well the current alpha) and possibly Opera 9.6 support true type font (ttf) embedding, and at least Safari supports SVG fonts through the same mechanism. A list apart had a good discussion about this a while back.

Add the following line in style.xml

<style name="Base.Theme.AppTheme" parent="Theme.AppCompat.DayNight.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme" parent="Base.Theme.AppTheme">
</style>

Now add the following line in style-v21,

  <style name="AppTheme" parent="Base.Theme.AppTheme">
    <item name="android:windowDrawsSystemBarBackgrounds">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

and set the theme as android:theme="@style/AppTheme"

It will make the status bar transparent.

A blog article from Localytics, Android Not As Fragmented as Many Think, lists most popular Android sizes and resolutions:

Another concern for Android developers is screen size and resolution. Of all app usage analyzed for this study, 41% of all sessions came from Android devices with 4.3 inch screens, by far the most popular size. 4 inch screens accounted for 22% of sessions, 3.2 inch screens for 11%, and 3.7 inch screens contributed 9%.

Resolutions were even less fragmented, however, with the most widely-seen screen resolution – 800 x 480 pixels – contributing 62% of the study’s sessions. The next most popular screen resolutions were 480 x 320 (14%), 960 x 540 (6%), 480 x 854 (5%) and 320 x 240 (5%).

Please note these statistics are from February 2012, which might be outdated today. Also, please always keep in mind that your app might be used under the inch sizes and resolutions not listed in this article.

EDIT: You should also be aware that there are Android "tablets" with large resolutions. The following quote is from the same article I mentioned:

Screen resolution and size are actually even less fragmented than handsets – 74% of Android tablet usage takes place on 7 inch devices with 1024 x 600 resolution. 22% are 10.1 inch devices with 1280 x 800 resolutions, so by taking into account two screen size/resolution combinations, developers should be able to easily reach nearly all of the Android tablet market.

For PHP 7.x

sudo apt-get install php-zip

For PHP 5.x

sudo apt-get install php5.x-zip
// (for example sudo apt-get install php5.6-zip)

And then restart the Apache server

sudo service apache2 restart

Basic idea behind having a private constructor is to restrict the instantiation of a class from outside by JVM, but if a class having a argument constructor, then it infers that one is intentionally instantiating.

You can get to the root from within each site using $_SERVER['DOCUMENT_ROOT']. For testing ONLY you can echo out the path to make sure it's working, if you do it the right way. You NEVER want to show the local server paths for things like includes and requires.

Site 1

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/';

Includes under site one would be at:

echo $_SERVER['DOCUMENT_ROOT'].'/includes/'; // should be '/main_web_folder/includes/';

Site 2

echo $_SERVER['DOCUMENT_ROOT']; //should be '/main_web_folder/blog/';

The actual code to access includes from site1 inside of site2 you would say:

include($_SERVER['DOCUMENT_ROOT'].'/../includes/file_from_site_1.php');

It will only use the relative path of the file executing the query if you try to access it by excluding the document root and the root slash:

 //(not as fool-proof or non-platform specific)
 include('../includes/file_from_site_1.php');

Included paths have no place in code on the front end (live) of the site anywhere, and should be secured and used in production environments only.

Additionally for URLs on the site itself you can make them relative to the domain. Browsers will automatically fill in the rest because they know which page they are looking at. So instead of:

<a href='http://www.__domain__name__here__.com/contact/'>Contact</a>

You should use:

<a href='/contact/'>Contact</a>

For good SEO you'll want to make sure that the URLs for the blog do not exist in the other domain, otherwise it may be marked as a duplicate site. With that being said you might also want to add a line to your robots.txt file for ONLY site1:

User-agent: *
Disallow: /blog/

Other possibilities:

Look up your IP address and include this snippet of code:

function is_dev(){
  //use the external IP from Google.
  //If you're hosting locally it's 127.0.01 unless you've changed it.
  $ip_address='xxx.xxx.xxx.xxx';

  if ($_SERVER['REMOTE_ADDR']==$ip_address){
     return true;
  } else {
     return false;
  } 
}

if(is_dev()){
    echo $_SERVER['DOCUMENT_ROOT'];       
}

Remember if your ISP changes your IP, as in you have a DCHP Dynamic IP, you'll need to change the IP in that file to see the results. I would put that file in an include, then require it on pages for debugging.

If you're okay with modern methods like using the browser console log you could do this instead and view it in the browser's debugging interface:

if(is_dev()){
    echo "<script>".PHP_EOL;
    echo "console.log('".$_SERVER['DOCUMENT_ROOT']."');".PHP_EOL;
    echo "</script>".PHP_EOL;       
}

You can try

LINUX

echo password | passwd username --stdin

UNIX

echo username:password | chpasswd -c

If you dont use "-c" argument, you need to change password next time.

Above example is technically incorrect. Per latest jQuery, use the prop() method should be used for things like disabled. See their API page.

To disable all form elements inside 'target', use the :input selector which matches all input, textarea, select and button elements.

$("#target :input").prop("disabled", true);

If you only want the elements, use this.

$("#target input").prop("disabled", true);

IE10 has uses the old syntax. So:

display: -ms-flexbox; /* will work on IE10 */
display: flex; /* is new syntax, will not work on IE10 */

see css-tricks.com/snippets/css/a-guide-to-flexbox:

(tweener) means an odd unofficial syntax from [2012] (e.g. display: flexbox;)

http://jsfiddle.net/9nyhh/1/

var thisExpressions = [/something/, /something_else/, /and_something_else/];
var thisExpressions2 = [/else/, /something_else/, /and_something_else/];
var thisString = 'else';

function matchInArray(string, expressions) {

    var len = expressions.length,
        i = 0;

    for (; i < len; i++) {
        if (string.match(expressions[i])) {
            return true;
        }
    }

    return false;

};

setTimeout(function() {
    console.log(matchInArray(thisString, thisExpressions));
    console.log(matchInArray(thisString, thisExpressions2));
}, 200)?

Also a bit late, but maybe helpful for some. I am using a combination of ConfigParser and JSON:

[Foo]
fibs: [1,1,2,3,5,8,13]

just read it with:

>>> json.loads(config.get("Foo","fibs"))
[1, 1, 2, 3, 5, 8, 13]

You can even break lines if your list is long (thanks @peter-smit):

[Bar]
files_to_check = [
     "/path/to/file1",
     "/path/to/file2",
     "/path/to/another file with space in the name"
     ]

Of course i could just use JSON, but i find config files much more readable, and the [DEFAULT] Section very handy.

When in a window, go to GO ---> ENTER LOCATION... And then copy paste this: /opt/lampp/htdocs

Now you are at the htdocs folder. Then you can add your files there, or in a new folder inside this one (for example "myproyects" folder and inside it your files... and then from a navigator you access it by writting: localhost/myproyects/nameofthefile.php

What I did to find it easily everytime, was right click on "myproyects" folder and "Make link..."... then I moved this link I created to the Desktop and then I didn't have to go anymore to the htdocs, but just enter the folder I created in my Desktop.

Hope it helps!!

You need to use OPENROWSET

Check this question: import-excel-spreadsheet-columns-into-sql-server-database

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

I know this is a really really old thread but I'd like to also point out another way which is actually really simple... This is some sample code:

#include <iostream>
#include <fstream>
#include <string>
using namespace std;

int main() {

    ifstream file("filename.txt");
    string content;

    while(file >> content) {
        cout << content << ' ';
    }
    return 0;
}

Here is a single function that will merge X amount of PDFs using PDFSharp

using PdfSharp;
using PdfSharp.Pdf;
using PdfSharp.Pdf.IO;

public static void MergePDFs(string targetPath, params string[] pdfs) {
    using(PdfDocument targetDoc = new PdfDocument()){
        foreach (string pdf in pdfs) {
            using (PdfDocument pdfDoc = PdfReader.Open(pdf, PdfDocumentOpenMode.Import)) {
                for (int i = 0; i < pdfDoc.PageCount; i++) {
                    targetDoc.AddPage(pdfDoc.Pages[i]);
                }
            }
        }
        targetDoc.Save(targetPath);
    }
}

I've moved what I've done from the question to an answer where more people are likely to see it.

What I've done is to have the creation endpoints at the nested endpoint, The canonical endpoint for modifying or querying an item is not at the nested resource.

So in this example (just listing the endpoints that change a resource)

• POST /companies/ creates a new company returns a link to the created company.
• POST /companies/{companyId}/departments when a department is put creates the new department returns a link to /departments/{departmentId}
• PUT /departments/{departmentId} modifies a department
• POST /departments/{deparmentId}/employees creates a new employee returns a link to /employees/{employeeId}

So there are root level resources for each of the collections. However the create is in the owning object.

There is a more efficient way of doing this in Windows 7. SETX is installed by default and supports connecting to other systems.

To modify a remote system's global environment variables, you would use

setx /m /s HOSTNAME-GOES-HERE VariableNameGoesHere VariableValueGoesHere

This does not require restarting Windows Explorer.

There are couple of ways to initialize the const members inside the class..

Definition of const member in general, needs initialization of the variable too..

1) Inside the class , if you want to initialize the const the syntax is like this

static const int a = 10; //at declaration

2) Second way can be

class A
{
  static const int a; //declaration
};

const int A::a = 10; //defining the static member outside the class

3) Well if you don't want to initialize at declaration, then the other way is to through constructor, the variable needs to be initialized in the initialization list(not in the body of the constructor). It has to be like this

class A
{
  const int b;
  A(int c) : b(c) {} //const member initialized in initialization list
};

If you had a table that already had a existing constraints based on lets say: name and lastname and you wanted to add one more unique constraint, you had to drop the entire constrain by:

ALTER TABLE your_table DROP CONSTRAINT constraint_name;

Make sure tha the new constraint you wanted to add is unique/ not null ( if its Microsoft Sql, it can contain only one null value) across all data on that table, and then you could re-create it.

ALTER TABLE table_name
ADD CONSTRAINT constraint_name UNIQUE (column1, column2, ... column_n);

The other answer is lacking some additional information also in the following post. For example, when the iPhone keep Connect / Disconnect in loop. So here is a better solution:

1. In vmware.log search the vid & pid of your iphone USB:
   Example:

   vmx | USB: Found device [name:Apple\ IR\ Receiver vid:05ac pid:12a8
   

2. Close vmware (to unlock .vmx)

3. In the .vmx, add:

   usb.quirks.device0 = "0xvid:0xpid skip-reset, skip-refresh, skip-setconfig"  
   

   Replace 0xvid:0xpid by the vid & pid found in vmware.log. Example:

   usb.quirks.device0 = "0x05ac:0x12a8 skip-reset, skip-refresh, skip-setconfig"
   

4. In vmware > Edit virtual machine > USB Controller : USB compatibility : USB 2.0
   Active : Automatically connect new USB Devices
   Active : Show all USB input devices
   Active : Share Bluetooth devices with the virtual Machine

5. Launch Mac OS and make sure that the mouse is Focus on vmware (or just use the login prompt if it appear)

in Firefox will not change the zoom only change scale!!!

I was able to fix it using the answer here: https://stackoverflow.com/a/32176571/1174024 But I have 150 modules. So I would have had to perform this step 150 times.

So I needed to do it a different way.

So first close the existing project, then Import it again, In the first step of the wizard choose "Gradle" project. Then the next step of the wizard has the Gradle project properties. Here it's going to ask you for, among other things, the Java SDK to use. The default will be "Project SDK". Do not use this default, instead hand pick your Java SDK from the list. Then finish the import.

Now the problem should go away.

In your Page_Load you will want to clear out the normal output and write your own, for example:

string json = "{\"name\":\"Joe\"}";
Response.Clear();
Response.ContentType = "application/json; charset=utf-8";
Response.Write(json);
Response.End();

To convert a C# object to JSON you can use a library such as Json.NET.

Instead of getting your .aspx page to output JSON though, consider using a Web Service (asmx) or WCF, both of which can output JSON.

Check permission issues, mysql config.

Also check if you haven't reached disk space, quota limits.

Note: Some systems are limiting number of files (not just space), deleting some old session files helped fixed the issue in my case.

Here are some:

"Ali".eql? "Ali"
=> true

The spaceship (<=>) method can be used to compare two strings in relation to their alphabetical ranking. The <=> method returns 0 if the strings are identical, -1 if the left hand string is less than the right hand string, and 1 if it is greater:

"Apples" <=> "Apples"
=> 0

"Apples" <=> "Pears"
=> -1

"Pears" <=> "Apples"
=> 1

A case insensitive comparison may be performed using the casecmp method which returns the same values as the <=> method described above:

"Apples".casecmp "apples"
=> 0

This is similar to some other answers, but perhaps a little more "Swifty":

// Load "mysoundname.wav"
if let soundURL = Bundle.main.url(forResource: "mysoundname", withExtension: "wav") {
    var mySound: SystemSoundID = 0
    AudioServicesCreateSystemSoundID(soundURL as CFURL, &mySound)
    // Play
    AudioServicesPlaySystemSound(mySound);
}

Note that this is a trivial example reproducing the effect of the code in the question. You'll need to make sure to import AudioToolbox, plus the general pattern for this kind of code would be to load your sounds when your app starts up, saving them in SystemSoundID instance variables somewhere, use them throughout your app, then call AudioServicesDisposeSystemSoundID when you're finished with them.

Set decoding to true

Your decoding is not set to true. If you don't have access to set the source to true. The code below will fix it for you.

$WorkingArray = json_decode(json_encode($data),true);

Service Events: Components can subscribe to service events. For example, two sibling components can subscribe to the same service event and respond by modifying their respective models. More on this below.

But make sure to unsubscribe to that on destroy of the parent component.

Your first attempt was close. Here is the simplistic approach using your idea.

file="somefileondisk"
lines=`cat $file`
for line in $lines; do
        echo "$line"
done

Ctrl-K, Ctrl-D

Will just prettify the entire document. Saves a lot of messing about, compared to delphi.

Make sure to remove all indents by first selecting everything with Ctrl+A then press Shift+Tab repeatedly until everything is aligned to the left. After you do that Ctrl+K, Ctrl+D will work the way you want them to.

You could also do the same but only to a selection of code by highlighting the block of code you want to realign, aligning it to the left side (Shift+Tab) and then after making sure you've selected the code you want to realign press Ctrl+K, Ctrl+F or just right click the highlighted code and select "Format Selection".

The table normally contains multiple rows. Use a loop and use row.Field<string>(0) to access the value of each row.

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>("File");
}

You can also access it via index:

foreach(DataRow row in dt.Rows)
{
    string file = row.Field<string>(0);
}

If you expect only one row, you can also use the indexer of DataRowCollection:

string file = dt.Rows[0].Field<string>(0); 

Since this fails if the table is empty, use dt.Rows.Count to check if there is a row:

if(dt.Rows.Count > 0)
    file = dt.Rows[0].Field<string>(0);

Standard SQL disallows references to column aliases in a WHERE clause. This restriction is imposed because when the WHERE clause is evaluated, the column value may not yet have been determined. For example, the following query is illegal:

SELECT id, COUNT(*) AS cnt FROM tbl_name WHERE cnt > 0 GROUP BY id;

you can use accept attribute for <input type="file"> read this docs http://www.w3schools.com/tags/att_input_accept.asp

thanks for existing answers, but added signal.getsignal()

import signal

# store default handler of signal.SIGINT
default_handler = signal.getsignal(signal.SIGINT)
catch_count = 0

def handler(signum, frame):
    global default_handler, catch_count
    catch_count += 1
    print ('wait:', catch_count)
    if catch_count > 3:
        # recover handler for signal.SIGINT
        signal.signal(signal.SIGINT, default_handler)
        print('expecting KeyboardInterrupt')

signal.signal(signal.SIGINT, handler)
print('Press Ctrl+c here')

while True:
    pass

You can use the "instanceof" operator to determine if an object is an instance of a certain class or not. If you do not know the name of an object's type, you can use its constructor property. The constructor property of objects, is a reference to the function that is used to initialize them. Example:

function Circle (x,y,radius) {
    this._x = x;
    this._y = y;
    this._radius = raduius;
}
var c1 = new Circle(10,20,5);

Now c1.constructor is a reference to the Circle() function. You can alsow use the typeof operator, but the typeof operator shows limited information. One solution is to use the toString() method of the Object global object. For example if you have an object, say myObject, you can use the toString() method of the global Object to determine the type of the class of myObject. Use this:

Object.prototype.toString.apply(myObject);

var fruits = ["apple","pear","peach"];
for (fruit of fruits) {
    console.log(fruits.indexOf(fruit));
    //it shows the index of every fruit from fruits
}

the for loop traverses the array, while the indexof property takes the value of the index that matches the array. P.D this method has some flaws with numbers, so use fruits

To refresh the component at regular intervals I found this the best method. In the ngOnInit method setTimeOut function

ngOnInit(): void {
  setTimeout(() => { this.ngOnInit() }, 1000 * 10)
}
//10 is the number of seconds

If you are running MySQL 5.6 onwards, you can make this operation online, allowing other sessions to read and write to your table while the operation is been performed:

ALTER TABLE tbl_Country DROP COLUMN IsDeleted, ALGORITHM=INPLACE, LOCK=NONE;

I've always used it on the command line and not as a library, but HTMLDOC gives me excellent results, and it handles at least some CSS (I couldn't easily see how much).

Here's a sample command line

htmldoc --webpage -t pdf --size letter --fontsize 10pt index.html > index.pdf

Cast the datetime to a date, then GROUP BY using this syntax:

SELECT SUM(foo), DATE(mydate) FROM a_table GROUP BY DATE(a_table.mydate);

Or you can GROUP BY the alias as @orlandu63 suggested:

SELECT SUM(foo), DATE(mydate) DateOnly FROM a_table GROUP BY DateOnly;

Though I don't think it'll make any difference to performance, it is a little clearer.

You can remove the entire line below:

 .map((res: Response) => res.json());

No need to use the map method at all.

I use:

cat /home/path/to/dump/file | psql -h localhost -U <user_name> -d <db_name>

Hope this will help someone.

We can access super class elements by using super keyword

Consider we have two classes, Parent class and Child class, with different implementations of method foo. Now in child class if we want to call the method foo of parent class, we can do so by super.foo(); we can also access parent elements by super keyword.

    class parent {
    String str="I am parent";
    //method of parent Class
    public void foo() {
        System.out.println("Hello World " + str);
    }
}

class child extends parent {
    String str="I am child";
    // different foo implementation in child Class
    public void foo() {
        System.out.println("Hello World "+str);
    }

    // calling the foo method of parent class
    public void parentClassFoo(){
        super.foo();
    }

    // changing the value of str in parent class and calling the foo method of parent class
    public void parentClassFooStr(){
        super.str="parent string changed";
        super.foo();
    }
}


public class Main{
        public static void main(String args[]) {
            child obj = new child();
            obj.foo();
            obj.parentClassFoo();
            obj.parentClassFooStr();
        }
    }

I agree that this is generally a bad idea. However, Commons Collections had a nice routine for getting the value by index if you really need to:

CollectionUtils.get(collection, index)

For length including white-space:

$("#id").val().length

For length without white-space:

$("#id").val().replace(/ /g,'').length

For removing only beginning and trailing white-space:

$.trim($("#test").val()).length

For example, the string " t e s t " would evaluate as:

//" t e s t "
$("#id").val(); 

//Example 1
$("#id").val().length; //Returns 9
//Example 2
$("#id").val().replace(/ /g,'').length; //Returns 4
//Example 3
$.trim($("#test").val()).length; //Returns 7

Here is a demo using all of them.

If you are still intrested in why this didn't work for you at first:

The reason you don't see changes you've made to the cell's style is because you do these changes before the form was shown, and so they are disregarded.

Changing cell styles in the events suggested here will do the job, but they are called multiple times causing your style changes to happen more times than you wish, and so aren't very efficient.

To solve this, either change the style after the point in your code in which the form is shown, or subscribe to the Shown event, and place your changes there (this is event is called significantly less than the other events suggested).

I had this question, but with a twist - I was trying to log different content to different files. I had information for a LowLevel debug log, and a HighLevel user log. I wanted the LowLevel to go to only one file, and the HighLevel to go to both a file, and a syslogd.

My solution was to configure the 3 appenders, and then setup the logging like this:

log4j.threshold=ALL
log4j.rootLogger=,LowLogger

log4j.logger.HighLevel=ALL,Syslog,HighLogger
log4j.additivity.HighLevel=false

The part that was difficult for me to figure out was that the 'log4j.logger' could have multiple appenders listed. I was trying to do it one line at a time.

Hope this helps someone at some point!

you need to initialize the object elements of the array.

GameObject[] houses = new GameObject[200];

for (int i=0;`i<house` i<houses.length; i++)
{ houses[i] = new GameObject();}

Of course you initialize elements selectively using different constructors anywhere else before you reference them.

$('select').val()  // Get's the value

$('select option:selected').val() ; // Get's the value

$('select').find('option:selected').val() ; // Get's the value

$('select option:selected').text()  // Gets you the text of the selected option

As per the current latest Facebook API version 3.2, For users you can use this generic method for getting profile picture is https://graph.facebook.com/v3.2/{user-id}/picture?type=square you can visit documentation for user picture here. The possible values for type parameter in URL can be small, normal, album, large, square

For Groups and Pages, the profile picture is not available directly. You have to get them using access token. For Groups you have to use User Access Token and for Pages you can use both User Access Token and Page Access Token.

You can get Group's or Page's Profile Picture using the generic URL: https://graph.facebook.com/v3.2/{user-id}/picture?access_token={access-token}&type=square

I hope this is helpful for people who are looking for Page or Group Profile picture.

I have been confronted with the same problem, so I went to :

/xampp/phpmyadmin/config.inc.php

I pasted the password which I had enter earlier then I was able to access phpmyadmin again, there in the privileges tab/ edit/ I chose no password and go then it all came back to life :)

Also you can change the user to admin but your phpmyadmin would be in admin side and your other localhost website will not work either.

Try this to move your table (tbl1) to tablespace (tblspc2).

alter table tb11 move tablespace tblspc2;

Default style you getting in res/value/style.xml like

  <style name="AppTheme.NoActionBar">
        <item name="windowActionBar">false</item>
        <item name="windowNoTitle">true</item>
  </style>

And just the below like in your activity tag,

android:theme="@style/AppTheme.NoActionBar"

I was presented with the same issue. The cause for me was Grunt concatenating my JavaScript file.

I was using a ;\n as a separator which caused the path to the source map to 404.

So dev tools was looking for jquery.min.map; instead of jquery.min.map.

I know that isn't the answer to the original question, but I am sure there are others out there with a similar Grunt configuration.

I see some clarification is in order on this. C and C++ do not define types differently. C++ was originally nothing more than an additional set of includes on top of C.

The problem that virtually all C/C++ developers have today, is a) universities are no longer teaching the fundamentals, and b) people don't understand the difference between a definition and a declaration.

The only reason such declarations and definitions exist is so that the linker can calculate address offsets to the fields in the structure. This is why most people get away with code that is actually written incorrectly-- because the compiler is able to determine addressing. The problem arises when someone tries to do something advance, like a queue, or a linked list, or piggying-backing an O/S structure.

A declaration begins with 'struct', a definition begins with 'typedef'.

Further, a struct has a forward declaration label, and a defined label. Most people don't know this and use the forward declaration label as a define label.

Wrong:

struct myStruct
   {
   int field_1;
   ...
   };

They've just used the forward declaration to label the structure-- so now the compiler is aware of it-- but it isn't an actual defined type. The compiler can calculate the addressing-- but this isn't how it was intended to be used, for reasons I will show momentarily.

People who use this form of declaration, must always put 'struct' in practicly every reference to it-- because it isn't an offical new type.

Instead, any structure that does not reference itself, should be declared and defined this way only:

typedef struct
   {
   field_1;
   ...
   }myStruct;

Now it's an actual type, and when used you can use at as 'myStruct' without having to prepend it with the word 'struct'.

If you want a pointer variable to that structure, then include a secondary label:

typedef struct
   {
   field_1;
   ...
   }myStruct,*myStructP;

Now you have a pointer variable to that structure, custom to it.

FORWARD DECLARATION--

Now, here's the fancy stuff, how the forward declaration works. If you want to create a type that refers to itself, like a linked list or queue element, you have to use a forward declaration. The compiler doesn't consider the structure defined until it gets to the semicolon at the very end, so it's just declared before that point.

typedef struct myStructElement
   {
   myStructElement*  nextSE;
   field_1;
   ...
   }myStruct;

Now, the compiler knows that although it doesn't know what the whole type is yet, it can still reference it using the forward reference.

Please declare and typedef your structures correctly. There's actually a reason.

Don't ever use JSON.parse without wrapping it in try-catch block:

// payload 
let userData = null;

try {
    // Parse a JSON
    userData = JSON.parse(payload); 
} catch (e) {
    // You can read e for more info
    // Let's assume the error is that we already have parsed the payload
    // So just return that
    userData = payload;
}

// Now userData is the parsed result

@jolly.exe

Nice example Jolly. I updated your version which limits the character length as opposed to the number of words. I also added setting the title to the real original innerHTML , so users can hover and see what is truncated.

HTML

<div id="stuff">a reallly really really long titleasdfasdfasdfasdfasdfasdfasdfadsf</div> 

JS

 function cutString(id){    
     var text = document.getElementById(id).innerHTML;         
     var charsToCutTo = 30;
        if(text.length>charsToCutTo){
            var strShort = "";
            for(i = 0; i < charsToCutTo; i++){
                strShort += text[i];
            }
            document.getElementById(id).title = "text";
            document.getElementById(id).innerHTML = strShort + "...";
        }            
     };

cutString('stuff'); 

For clean code, you might make use of the javascript file here: http://rafael.adm.br/css_browser_selector/ By including the line:

<script src="css_browser_selector.js" type="text/javascript"></script>

You can write subsequent css with the following simple pattern:

.ie7 [thing] {
  background-color: orange
}
.chrome [thing] {
  background-color: gray
}

Another possible solution, in case a string is an ASCII string, is to maintain an array of 256 boolean elements to denote ASCII character appearance in a string. If a character appeared for the first time, we keep it and append to the result. Otherwise just skip it.

public String removeDuplicates(String input) {
    boolean[] chars = new boolean[256];
    StringBuilder resultStringBuilder = new StringBuilder();
    for (Character c : input.toCharArray()) {
        if (!chars[c]) {
            resultStringBuilder.append(c);
            chars[c] = true;
        }
    }
    return resultStringBuilder.toString();
}

This approach will also work with Unicode string. You just need to increase chars size.

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.

Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled

Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is

1. Remove the XAML for the ad
2. Remove the xmlns declaration (usually at the top of the page, but sometimes will be declared in the ad itself)
3. Remove the bad DLL (the one ending in .SDK )
4. Do a Clean and then Build (clean out anything remaining from the DLL)
5. Add the xmlns reference (actual reference is below)
6. Add the ad to the page (example below)

Here is the xmlns reference:

xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI" 

Then the ad itself:

<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480"                    AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/> 

I know this was answered long ago, but if you don't mind creating the button dynamically, this works using only the jQuery framework:

$(document).ready(function() {_x000D_
  $button = $('<input id="1" type="button" value="ahaha" />');_x000D_
  $('body').append($button);_x000D_
  $button.click(function() {_x000D_
    console.log("Id clicked: " + this.id ); // or $(this) or $button_x000D_
  });_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<p>And here is my HTML page:</p>_x000D_
_x000D_
<div class="Title">Welcome!</div>

Need to convert the the key from hex to dec before base64_encoding and then send it for handshake.

$hashedKey = sha1($key. "258EAFA5-E914-47DA-95CA-C5AB0DC85B11",true);

$rawToken = "";
    for ($i = 0; $i < 20; $i++) {
      $rawToken .= chr(hexdec(substr($hashedKey,$i*2, 2)));
    }
$handshakeToken = base64_encode($rawToken) . "\r\n";

$handshakeResponse = "HTTP/1.1 101 Switching Protocols\r\nUpgrade: websocket\r\nConnection: Upgrade\r\nSec-WebSocket-Accept: $handshakeToken\r\n";

Huffman has a static cost, the Huffman table, so I disagree it's a good choice.

There are adaptative versions which do away with this, but the compression rate may suffer. Actually, the question you should ask is "what algorithm to compress text strings with these characteristics". For instance, if long repetitions are expected, simple Run-Lengh Encoding might be enough. If you can guarantee that only English words, spaces, punctiation and the occasional digits will be present, then Huffman with a pre-defined Huffman table might yield good results.

Generally, algorithms of the Lempel-Ziv family have very good compression and performance, and libraries for them abound. I'd go with that.

With the information that what's being compressed are URLs, then I'd suggest that, before compressing (with whatever algorithm is easily available), you CODIFY them. URLs follow well-defined patterns, and some parts of it are highly predictable. By making use of this knowledge, you can codify the URLs into something smaller to begin with, and ideas behind Huffman encoding can help you here.

For example, translating the URL into a bit stream, you could replace "http" with the bit 1, and anything else with the bit "0" followed by the actual procotol (or use a table to get other common protocols, like https, ftp, file). The "://" can be dropped altogether, as long as you can mark the end of the protocol. Etc. Go read about URL format, and think on how they can be codified to take less space.

You can also create a new jsp file sayng that form is submited and in your main action file just write its file name

Eg. Your form is submited is in a file succes.jsp Then your action file will have

Request.sendRedirect("success.jsp")

Set the image's width to 100%, and the image's height will adjust itself:

<img style="width:100%;" id="image" src="...">

If you have a custom CSS, then:

HTML:

<img id="image" src="...">

CSS:

#image
{
    width: 100%;
}

Also, you could do File -> View Source next time, or maybe Google.

The problem is with percentage sizing. You are not defining the size of the parent div (the new one), so the browser can not report the size to the Google Maps API. Giving the wrapper div a specific size, or a percentage size if the size of its parent can be determined, will work.

See this explanation from Mike Williams' Google Maps API v2 tutorial:

If you try to use style="width:100%;height:100%" on your map div, you get a map div that has zero height. That's because the div tries to be a percentage of the size of the <body>, but by default the <body> has an indeterminate height.

There are ways to determine the height of the screen and use that number of pixels as the height of the map div, but a simple alternative is to change the <body> so that its height is 100% of the page. We can do this by applying style="height:100%" to both the <body> and the <html>. (We have to do it to both, otherwise the <body> tries to be 100% of the height of the document, and the default for that is an indeterminate height.)

Add the 100% size to html and body in your css

    html, body, #map-canvas {
        margin: 0;
        padding: 0;
        height: 100%;
        width: 100%;
    }

Add it inline to any divs that don't have an id:

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

You can use the built-in http module to do an http.request().

However if you want to simplify the API you can use a module such as superagent

Ajax post and upload file is possible. I'm using jQuery $.ajax function to load my files. I tried to use the XHR object but could not get results on the server side with PHP.

var formData = new FormData();
formData.append('file', $('#file')[0].files[0]);

$.ajax({
       url : 'upload.php',
       type : 'POST',
       data : formData,
       processData: false,  // tell jQuery not to process the data
       contentType: false,  // tell jQuery not to set contentType
       success : function(data) {
           console.log(data);
           alert(data);
       }
});

As you can see, you must create a FormData object, empty or from (serialized? - $('#yourForm').serialize()) existing form, and then attach the input file.

Here is more information: - How to upload a file using jQuery.ajax and FormData - Uploading files via jQuery, object FormData is provided and no file name, GET request

For the PHP process you can use something like this:

//print_r($_FILES);
$fileName = $_FILES['file']['name'];
$fileType = $_FILES['file']['type'];
$fileError = $_FILES['file']['error'];
$fileContent = file_get_contents($_FILES['file']['tmp_name']);

if($fileError == UPLOAD_ERR_OK){
   //Processes your file here
}else{
   switch($fileError){
     case UPLOAD_ERR_INI_SIZE:   
          $message = 'Error al intentar subir un archivo que excede el tamaño permitido.';
          break;
     case UPLOAD_ERR_FORM_SIZE:  
          $message = 'Error al intentar subir un archivo que excede el tamaño permitido.';
          break;
     case UPLOAD_ERR_PARTIAL:    
          $message = 'Error: no terminó la acción de subir el archivo.';
          break;
     case UPLOAD_ERR_NO_FILE:    
          $message = 'Error: ningún archivo fue subido.';
          break;
     case UPLOAD_ERR_NO_TMP_DIR: 
          $message = 'Error: servidor no configurado para carga de archivos.';
          break;
     case UPLOAD_ERR_CANT_WRITE: 
          $message= 'Error: posible falla al grabar el archivo.';
          break;
     case  UPLOAD_ERR_EXTENSION: 
          $message = 'Error: carga de archivo no completada.';
          break;
     default: $message = 'Error: carga de archivo no completada.';
              break;
    }
      echo json_encode(array(
               'error' => true,
               'message' => $message
            ));
}

HashMap operation is dependent factor of hashCode implementation. For the ideal scenario lets say the good hash implementation which provide unique hash code for every object (No hash collision) then the best, worst and average case scenario would be O(1). Let's consider a scenario where a bad implementation of hashCode always returns 1 or such hash which has hash collision. In this case the time complexity would be O(n).

Now coming to the second part of the question about memory, then yes memory constraint would be taken care by JVM.

Note: you may need to check what is the name of the default.html

default.html is the file that load by default in the root folder.

You can create one file that contains the set schema ... statement and then include the actual file you want to run:

Create a file run_insert.sql:

set schema 'my_schema_01';
\i myInsertFile.sql

Then call this using:

psql -d myDataBase -a -f run_insert.sql

It looks like what you want to do is remove your first merge. You could follow the following procedure:

git checkout master      # Let's make sure we are on master branch
git reset --hard master~ # Let's get back to master before the merge
git pull                 # or git merge remote/master
git merge topic

That would give you what you want.

This code achieves what you want --- also its weird and certainly buggy:

I observed that it works when:

a) you specify the index_col rel. to the number of columns you really use -- so its three columns in this example, not four (you drop dummy and start counting from then onwards)

b) same for parse_dates

c) not so for usecols ;) for obvious reasons

d) here I adapted the names to mirror this behaviour

import pandas as pd
from StringIO import StringIO

csv = """dummy,date,loc,x
bar,20090101,a,1
bar,20090102,a,3
bar,20090103,a,5
bar,20090101,b,1
bar,20090102,b,3
bar,20090103,b,5
"""

df = pd.read_csv(StringIO(csv),
        index_col=[0,1],
        usecols=[1,2,3], 
        parse_dates=[0],
        header=0,
        names=["date", "loc", "", "x"])

print df

which prints

                x
date       loc   
2009-01-01 a    1
2009-01-02 a    3
2009-01-03 a    5
2009-01-01 b    1
2009-01-02 b    3
2009-01-03 b    5

If you have to deal with data that large you'll need to split it up into manageable chunks. It won't all fit into memory on any small computer. You can probably load a portion of the data from disk (whatever reasonably fits), perform your calculations and changes to it, store it to disk, then repeat until complete.

Another approach that's a little more semantic is to have a UL defined as your total 6 image width, each LI defined as float left and width defined - so that when LI #7 hits, it runs into the boundry of the UL, and is pushed down to the new row. You'll still have an open float that you'll want to clear after the /UL - but that can be done on the next element of the page, or as a clear div. Here's sort of the idea, you may have to mess with actual values, but this should give you the idea. The code is a little cleaner.

 <style type="text/css"> 
ul#imageSet { width: 600px; margin: 0; padding:0; }
ul#imageSet li { float: left; width: 100px;  height: 188px; margin: 0; padding:0; position: relative; list-style-type: none; }
.cornerimage { position: absolute; bottom: 0; right: 0; } 
h3.nextelement { clear: both; }

# into a 2N-bit accumulator
# Use shift-add so that it's O(base_2_log(N)) not O(N)

for numa, numb in ((3, 5), (-3, 5), (3, -5), (-3, -5), (-127, -127)):
    print numa, numb,
    accum = 0

Better create an image view and add it as a sub view to the cell.Then you can get the desired frame size.

The configuration file is called applicationhost.config. It's stored here:

My Documents > IIS Express > config

usually, but not always, one of these paths will work

%userprofile%\documents\iisexpress\config\applicationhost.config
%userprofile%\my documents\iisexpress\config\applicationhost.config

Update for VS2019
If you're using Visual Studio 2019+ check this path:

$(solutionDir)\.vs\{projectName}\config\applicationhost.config

Update for VS2015 (credit: @Talon)
If you're using Visual Studio 2015-2017 check this path:

$(solutionDir)\.vs\config\applicationhost.config

In Visual Studio 2015+ you can also configure which applicationhost.config file is used by altering the <UseGlobalApplicationHostFile>true|false</UseGlobalApplicationHostFile> setting in the project file (eg: MyProject.csproj). (source: MSDN forum)

In case you're still wondering how to do it, then add: &feature=youtu.be&hd=1 Actually now I checked, this works only when you're sending the URL to someone else, not on embed.

If you want to update your project using SVN then first of all:

1. Go to the path on which your project is stored through command prompt.

2. Use the command SVN update

That's it.

Take a look at http://developer.android.com/reference/org/json/JSONTokener.html

This might fix your issue.

For me I solved this error just by adding this line inside repository

maven { url 'https://maven.google.com' }

Thought to add my solution for this, after spending a few hours on the same error :(

The guys above were correct that the first thing you should check is whether you had missed adding any frameworks, see the steps provided by Pruthvid above.

My problem, it turned out, was a compile class missing after I deleted it, and later added it back in again.

Check your "Compile Sources" as shown for the reported error classes. Add in any missing classes that you created.

Use the browser/chrome postman plugin to check the CORS/SOP like a website. Use desktop application instead to avoid these controls.

This is deletes the table table_name.

Replace it with the name of the table, which shall be deleted.

DELETE FROM table_name;

After searching for an hour or two ,I've found a simple solution below.

const date = new Date(`${date from client} GMT`);

inside double ticks, there is a date from client side plust GMT.

I'm first time commenting, constructive criticism will be welcomed.

Another way to do it using just the glob module. Just seed the rglob method with a starting base directory and a pattern to match and it will return a list of matching file names.

import glob
import os

def _getDirs(base):
    return [x for x in glob.iglob(os.path.join( base, '*')) if os.path.isdir(x) ]

def rglob(base, pattern):
    list = []
    list.extend(glob.glob(os.path.join(base,pattern)))
    dirs = _getDirs(base)
    if len(dirs):
        for d in dirs:
            list.extend(rglob(os.path.join(base,d), pattern))
    return list

In 12c, here's the new way:

select bla
  from bla
 where bla
 order by finaldate desc
 fetch first 1 rows only; 

How nice is that!

Copy the mail as a document link (right click on the mail and you should get this option) and paste it in the new mail. This worked for me

First off, you have to specify you wish to use Document Literal style:

$client = new SoapClient(NULL, array(
    'location' => 'https://example.com/path/to/service',
    'uri' => 'http://example.com/wsdl',
    'trace' => 1,
    'use' => SOAP_LITERAL)
);

Then, you need to transform your data into a SoapVar; I've written a simple transform function:

function soapify(array $data)
{
        foreach ($data as &$value) {
                if (is_array($value)) {
                        $value = soapify($value);
                }
        }

        return new SoapVar($data, SOAP_ENC_OBJECT);
}

Then, you apply this transform function onto your data:

$data = soapify(array(
    'Acquirer' => array(
        'Id' => 'MyId',
        'UserId' => 'MyUserId',
        'Password' => 'MyPassword',
    ),
));

Finally, you call the service passing the Data parameter:

$method = 'Echo';

$result = $client->$method(new SoapParam($data, 'Data'));

Try this out:

<script type="text/javascript">
    function test
    {
        alert("hello world");  //write your logic here like ajax
    }
</script>

<form action="javascript:test();" >
    firstName : <input type="text" name="firstName" id="firstName" required/><br/>
    lastName : <input type="text" name="lastName" id="lastName" required/><br/>
    email : <input type="email" name="email" id="email"/><br/>
    <input type="submit" value="Get It!" name="submit" id="submit"/>
</form>

for a button in a collapsed navbar nothing above worked for me so in my css file i did.....

.navbar button {
    margin:auto;
}

and it worked!!

Following line should be called before you add your component

pnlButton.setLayout(null);

Above will set your content panel to use absolute layout. This means you'd always have to set your component's bounds explicitly by using setBounds method.

In general I wouldn't recommend using absolute layout.

In an instance where you want to set a placeholder and not have a default value be selected, you can use this option.

      <select defaultValue={'DEFAULT'} >
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>

Here the user is forced to pick an option!

EDIT

If this is a controlled component

In this case unfortunately you will have to use both defaultValue and value violating React a bit. This is because react by semantics does not allow setting a disabled value as active.

 function TheSelectComponent(props){
     let currentValue = props.curentValue || "DEFAULT";
     return(
      <select value={currentValue} defaultValue={'DEFAULT'} onChange={props.onChange}>
        <option value="DEFAULT" disabled>Choose a salutation ...</option>
        <option value="1">Mr</option>
        <option value="2">Mrs</option>
        <option value="3">Ms</option>
        <option value="4">Miss</option>
        <option value="5">Dr</option>
      </select>
    )
}

Do you mean this?

def perform(fun, *args):
    fun(*args)

def action1(args):
    # something

def action2(args):
    # something

perform(action1)
perform(action2, p)
perform(action3, p, r)

you have to set the tableName you want to your dtimage that is for instance

dtImage.TableName="mydtimage";


if(!ds.Tables.Contains(dtImage.TableName))
        ds.Tables.Add(dtImage);

it will be reflected in dataset because dataset is a container of your datatable dtimage and you have a reference on your dtimage

I made a performance test comparing split with regex, with a string and doing it with a for loop.

It seems that the for loop is the fastest.

NOTE: this code 'as is' is not useful for windows nor macos endline, but should be ok to compare performance.

Split with string:

split('\n').length;

Split with regex:

split(/\n/).length;

Split using for:

var length = 0;
for(var i = 0; i < sixteen.length; ++i)
  if(sixteen[i] == s)
    length++;

I design & implemented a simple finite state machine example with java.

IFiniteStateMachine: The public interface to manage the finite state machine
such as add new states to the finite state machine or transit to next states by
specific actions.

interface IFiniteStateMachine {
    void setStartState(IState startState);

    void setEndState(IState endState);

    void addState(IState startState, IState newState, Action action);

    void removeState(String targetStateDesc);

    IState getCurrentState();

    IState getStartState();

    IState getEndState();

    void transit(Action action);
}

IState: The public interface to get state related info
such as state name and mappings to connected states.

interface IState {
    // Returns the mapping for which one action will lead to another state
    Map<String, IState> getAdjacentStates();

    String getStateDesc();

    void addTransit(Action action, IState nextState);

    void removeTransit(String targetStateDesc);
}

Action: the class which will cause the transition of states.

public class Action {
    private String mActionName;

    public Action(String actionName) {
        mActionName = actionName;
    }

    String getActionName() {
        return mActionName;
    }

    @Override
    public String toString() {
        return mActionName;
    }

}

StateImpl: the implementation of IState. I applied data structure such as HashMap to keep Action-State mappings.

public class StateImpl implements IState {
    private HashMap<String, IState> mMapping = new HashMap<>();
    private String mStateName;

    public StateImpl(String stateName) {
        mStateName = stateName;
    }

    @Override
    public Map<String, IState> getAdjacentStates() {
        return mMapping;
    }

    @Override
    public String getStateDesc() {
        return mStateName;
    }

    @Override
    public void addTransit(Action action, IState state) {
        mMapping.put(action.toString(), state);
    }

    @Override
    public void removeTransit(String targetStateDesc) {
        // get action which directs to target state
        String targetAction = null;
        for (Map.Entry<String, IState> entry : mMapping.entrySet()) {
            IState state = entry.getValue();
            if (state.getStateDesc().equals(targetStateDesc)) {
                targetAction = entry.getKey();
            }
        }
        mMapping.remove(targetAction);
    }

}

FiniteStateMachineImpl: Implementation of IFiniteStateMachine. I use ArrayList to keep all the states.

public class FiniteStateMachineImpl implements IFiniteStateMachine {
    private IState mStartState;
    private IState mEndState;
    private IState mCurrentState;
    private ArrayList<IState> mAllStates = new ArrayList<>();
    private HashMap<String, ArrayList<IState>> mMapForAllStates = new HashMap<>();

    public FiniteStateMachineImpl(){}
    @Override
    public void setStartState(IState startState) {
        mStartState = startState;
        mCurrentState = startState;
        mAllStates.add(startState);
        // todo: might have some value
        mMapForAllStates.put(startState.getStateDesc(), new ArrayList<IState>());
    }

    @Override
    public void setEndState(IState endState) {
        mEndState = endState;
        mAllStates.add(endState);
        mMapForAllStates.put(endState.getStateDesc(), new ArrayList<IState>());
    }

    @Override
    public void addState(IState startState, IState newState, Action action) {
        // validate startState, newState and action

        // update mapping in finite state machine
        mAllStates.add(newState);
        final String startStateDesc = startState.getStateDesc();
        final String newStateDesc = newState.getStateDesc();
        mMapForAllStates.put(newStateDesc, new ArrayList<IState>());
        ArrayList<IState> adjacentStateList = null;
        if (mMapForAllStates.containsKey(startStateDesc)) {
            adjacentStateList = mMapForAllStates.get(startStateDesc);
            adjacentStateList.add(newState);
        } else {
            mAllStates.add(startState);
            adjacentStateList = new ArrayList<>();
            adjacentStateList.add(newState);
        }
        mMapForAllStates.put(startStateDesc, adjacentStateList);

        // update mapping in startState
        for (IState state : mAllStates) {
            boolean isStartState = state.getStateDesc().equals(startState.getStateDesc());
            if (isStartState) {
                startState.addTransit(action, newState);
            }
        }
    }

    @Override
    public void removeState(String targetStateDesc) {
        // validate state
        if (!mMapForAllStates.containsKey(targetStateDesc)) {
            throw new RuntimeException("Don't have state: " + targetStateDesc);
        } else {
            // remove from mapping
            mMapForAllStates.remove(targetStateDesc);
        }

        // update all state
        IState targetState = null;
        for (IState state : mAllStates) {
            if (state.getStateDesc().equals(targetStateDesc)) {
                targetState = state;
            } else {
                state.removeTransit(targetStateDesc);
            }
        }

        mAllStates.remove(targetState);

    }

    @Override
    public IState getCurrentState() {
        return mCurrentState;
    }

    @Override
    public void transit(Action action) {
        if (mCurrentState == null) {
            throw new RuntimeException("Please setup start state");
        }
        Map<String, IState> localMapping = mCurrentState.getAdjacentStates();
        if (localMapping.containsKey(action.toString())) {
            mCurrentState = localMapping.get(action.toString());
        } else {
            throw new RuntimeException("No action start from current state");
        }
    }

    @Override
    public IState getStartState() {
        return mStartState;
    }

    @Override
    public IState getEndState() {
        return mEndState;
    }
}

example:

public class example {

    public static void main(String[] args) {
        System.out.println("Finite state machine!!!");
        IState startState = new StateImpl("start");
        IState endState = new StateImpl("end");
        IFiniteStateMachine fsm = new FiniteStateMachineImpl();
        fsm.setStartState(startState);
        fsm.setEndState(endState);
        IState middle1 = new StateImpl("middle1");
        middle1.addTransit(new Action("path1"), endState);
        fsm.addState(startState, middle1, new Action("path1"));
        System.out.println(fsm.getCurrentState().getStateDesc());
        fsm.transit(new Action(("path1")));
        System.out.println(fsm.getCurrentState().getStateDesc());
        fsm.addState(middle1, endState, new Action("path1-end"));
        fsm.transit(new Action(("path1-end")));
        System.out.println(fsm.getCurrentState().getStateDesc());
        fsm.addState(endState, middle1, new Action("path1-end"));
    }

If you use the gson.JsonObject you can have something like that:

import com.google.gson.JsonObject;
import com.google.gson.JsonParser;

String jsonString = "{'test1':'value1','test2':{'id':0,'name':'testName'}}"
JsonObject jsonObject = (JsonObject) jsonParser.parse(jsonString)

set a=AAA BBB CCC DDD EEE FFF
set a=%a:~6,1%

This code finds the 5th character in the string. If I wanted to find the 9th string, I would replace the 6 with 10 (add one).

tooltips: {
          callbacks: {
            label: (tooltipItem, data) => {
              // data for manipulation
              return data.datasets[tooltipItem.datasetIndex].data[tooltipItem.index];
            },
          },
        },

While it is not free (but $39), FireDaemon has worked so well for me I have to recommend it. It will run your batch file but has loads of additional and very useful functionality such as scheduling, service up monitoring, GUI or XML based install of services, dependencies, environmental variables and log management.

I started out using FireDaemon to launch JBoss application servers (run.bat) but shortly after realized that the richness of the FireDaemon configuration abilities allowed me to ditch the batch file and recreate the intent of its commands in the FireDaemon service definition.

There's also a SUPER FireDaemon called Trinity which you might want to look at if you have a large number of Windows servers on which to manage this service (or technically, any service).

As per node js doc process.cwd()

cwd is a method of global object process, returns a string value which is the current working directory of the Node.js process.

As per node js doc __dirname

The directory name of current script as a string value. __dirname is not actually a global but rather local to each module.

Let me explain with example,

suppose we have a main.js file resides inside C:/Project/main.js and running node main.js both these values return same file

or simply with following folder structure

Project 
+-- main.js
+--lib
   +-- script.js

main.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

suppose we have another file script.js files inside a sub directory of project ie C:/Project/lib/script.js and running node main.js which require script.js

main.js

require('./lib/script.js')
console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project
console.log(__dirname===process.cwd())
// true

script.js

console.log(process.cwd())
// C:\Project
console.log(__dirname)
// C:\Project\lib
console.log(__dirname===process.cwd())
// false

For you LINQers out there that never use a regular dictionary constructor

myCollection.ToDictionary(x => x.PartNumber, x => x.PartDescription, StringComparer.OrdinalIgnoreCase)

Here is the perfect coding which checks whether the Combo Box Item is Selected or not

if (string.IsNullOrEmpty(comboBox1.Text))
{
    MessageBox.Show("No Item is Selected"); 
}
else
{
    MessageBox.Show("Item Selected is:" + comboBox1.Text);
}

I had the duplicate definition of connection string in my Project Cms.And the Context class is named:CmsContext

In my case, the problem was solved, as I changed the connectionsting in Web.config as follow:in first one name is CmsContext and it's related to main project .in second one name is DefaultConnection and it's related to Identity

<add name="CmsContext" providerName="System.Data.SqlClient" connectionString="Data Source=DESKTOP-2NQSP1P\SQLEXPRESS;  Initial Catalog=CmsDB;Integrated Security=True;" />
</connectionStrings>

I think there is another elegant solution.

What you want to do is (safely) "pass" the type of the generic type parameter up from the concerete class to the superclass.

If you allow yourself to think of the class type as "metadata" on the class, that suggests the Java method for encoding metadata in at runtime: annotations.

First define a custom annotation along these lines:

import java.lang.annotation.*;

@Target(ElementType.TYPE)
@Retention(RetentionPolicy.RUNTIME)
public @interface EntityAnnotation {
    Class entityClass();
}

You can then have to add the annotation to your subclass.

@EntityAnnotation(entityClass =  PassedGenericType.class)
public class Subclass<PassedGenericType> {...}

Then you can use this code to get the class type in your base class:

import org.springframework.core.annotation.AnnotationUtils;
.
.
.

private Class getGenericParameterType() {
    final Class aClass = this.getClass();
    EntityAnnotation ne = 
         AnnotationUtils.findAnnotation(aClass, EntityAnnotation.class);

    return ne.entityClass();
}

Some limitations of this approach are:

1. You specify the generic type (PassedGenericType) in TWO places rather than one which is non-DRY.
2. This is only possible if you can modify the concrete subclasses.

Try this : (http://jsfiddle.net/TpqVx/)

.left-div {
    float: left;
    width: 100px;
    /*height: 20px;*/
    margin-right: 8px;
    background-color: linen;
}
.right-div {

    margin-left: 108px;
    background-color: lime;
}??

<div class="left-div">
    &nbsp;
</div>
<div class="right-div">
    My requirements are <b>[A]</b> Content in the two divs should line up at the top, <b>[B]</b> Long text in right-div should not wrap underneath left-div, and <b>[C]</b> I do not want to specify a width of right-div. I don't want to set the width of right-div because this markup needs to work within different widths.
</div>
<div style='clear:both;'>&nbsp;</div>

Hints :

• Just use float:left in your left-most div only.
• No real reason to use height, but anyway...
• Good practice to use <div 'clear:both'>&nbsp;</div> after your last div.

Depending on your version:

Python 2.x:

for key, val in PIX0.iteritems():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

Python 3.x:

for key, val in PIX0.items():
    NUM = input("Which standard has a resolution of {!r}?".format(val))
    if NUM == key:
        print ("Nice Job!")
        count = count + 1
    else:
        print("I'm sorry but thats wrong. The correct answer was: {!r}.".format(key))

You should also get in the habit of using the new string formatting syntax ({} instead of % operator) from PEP 3101:

https://www.python.org/dev/peps/pep-3101/

I disagree SpringJPA makes live easy. Yes, it provides some classes and you can make some simple DAO fast, but in fact, it's all you can do. If you want to do something more than findById() or save, you must go through hell:

• no EntityManager access in org.springframework.data.repository classes (this is basic JPA class!)
• own transaction management (hibernate transactions disallowed)
• huge problems with more than one datasources configuration
• no datasource pooling (HikariCP must be in use as third party library)

Why own transaction management is an disadvantage? Since Java 1.8 allows default methods into interfaces, Spring annotation based transactions, simple doesn't work.

Unfortunately, SpringJPA is based on reflections, and sometimes you need to point a method name or entity package into annotations (!). That's why any refactoring makes big crash. Sadly, @Transactional works for primary DS only :( So, if you have more than one DataSources, remember - transactions works just for primary one :)

What are the main differences between Hibernate and Spring Data JPA?

Hibernate is JPA compatibile, SpringJPA Spring compatibile. Your HibernateJPA DAO can be used with JavaEE or Hibernate Standalone, when SpringJPA can be used within Spring - SpringBoot for example

When should we not use Hibernate or Spring Data JPA? Also, when may Spring JDBC template perform better than Hibernate / Spring Data JPA?

Use Spring JDBC only when you need to use much Joins or when you need to use Spring having multiple datasource connections. Generally, avoid JPA for Joins.

But my general advice, use fresh solution—Daobab (http://www.daobab.io). Daobab is my Java and any JPA engine integrator, and I believe it will help much in your tasks :)

You can try this

decimal(18,1)

The length of numbers should be totally 18. The length of numbers after the decimal point should be 1 only and not more than that.

You can also use the data-interval attribute eg. <div class="carousel" data-interval="10000">

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

                measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
                recycler.recycleView(view);
            }

None/Null is a data type of the class NoneType in pyspark/python so, Below will not work as you are trying to compare NoneType object with string object

df[df.dt_mvmt == None].count() 0 df[df.dt_mvmt != None].count() 0

correct

df=df.where(col("dt_mvmt").isNotNull()) returns all records with dt_mvmt as None/Null

Try switching input interface. C++ expects a keyboard to be plugged in to your computer, not a scanner. There may be peripherals conflict issues here. I didn't check in ISO Standard if keyboard input interface is mandatory, but that is true for all compilers I ever used. But maybe scanner input is now available in C99, and in this case your program should indeed work. If not you'll have to wait the next standard release and upgrade of compilers.

A 2.0 XPath that works:

//*[tokenize(@class,'\s+')='atag']

or with a variable:

//*[tokenize(@class,'\s+')=$classname]

It formats the string as two uppercase hexadecimal characters.

In more depth, the argument "X2" is a "format string" that tells the ToString() method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.

byte.ToString() without any arguments returns the number in its natural decimal representation, with no padding.

Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString() methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString().

To Summarize:

HashMap works on the principle of hashing

put(key, value): HashMap stores both key and value object as Map.Entry. Hashmap applies hashcode(key) to get the bucket. if there is collision ,HashMap uses LinkedList to store object.

get(key): HashMap uses Key Object's hashcode to find out bucket location and then call keys.equals() method to identify correct node in LinkedList and return associated value object for that key in Java HashMap.

You can try this way also.

<?php
     $obj = json_decode("{}"); 
     var_dump($obj);
?>

Output:

object(stdClass)#1 (0) { }

This function should work for all types of select (multiple, select, select2):

$.fn.Reset_List_To_Default_Value = function()
{
    $.each($(this), function(index, el) {
        var Founded = false;

        $(this).find('option').each(function(i, opt) {
            if(opt.defaultSelected){
                opt.selected = true;
                Founded = true;
            }
        });

        if(!Founded)
        {
            if($(this).attr('multiple'))
            {
                $(this).val([]);
            }
            else
            {
                $(this).val("");
            }
        }
        $(this).trigger('change');
    });
}

To use it just call:

$('select').Reset_List_To_Default_Value();

"use strict";

Basically it enables the strict mode.

Strict Mode is a feature that allows you to place a program, or a function, in a "strict" operating context. In strict operating context, the method form binds this to the objects as before. The function form binds this to undefined, not the global set objects.

As per your comments you are telling some differences will be there. But it's your assumption. The Node.js code is nothing but your JavaScript code. All Node.js code are interpreted by the V8 JavaScript engine. The V8 JavaScript Engine is an open source JavaScript engine developed by Google for Chrome web browser.

So, there will be no major difference how "use strict"; is interpreted by the Chrome browser and Node.js.

Please read what is strict mode in JavaScript.

For more information:

1. Strict mode
2. ECMAScript 5 Strict mode support in browsers
3. Strict mode is coming to town
4. Compatibility table for strict mode
5. Stack Overflow questions: what does 'use strict' do in JavaScript & what is the reasoning behind it

ECMAScript 6 Code & strict mode. Following is brief from the specification:

10.2.1 Strict Mode Code

An ECMAScript Script syntactic unit may be processed using either unrestricted or strict mode syntax and semantics. Code is interpreted as strict mode code in the following situations:

• Global code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive (see 14.1.1).
• Module code is always strict mode code.
• All parts of a ClassDeclaration or a ClassExpression are strict mode code.
• Eval code is strict mode code if it begins with a Directive Prologue that contains a Use Strict Directive or if the call to eval is a direct eval (see 12.3.4.1) that is contained in strict mode code.
• Function code is strict mode code if the associated FunctionDeclaration, FunctionExpression, GeneratorDeclaration, GeneratorExpression, MethodDefinition, or ArrowFunction is contained in strict mode code or if the code that produces the value of the function’s [[ECMAScriptCode]] internal slot begins with a Directive Prologue that contains a Use Strict Directive.
• Function code that is supplied as the arguments to the built-in Function and Generator constructors is strict mode code if the last argument is a String that when processed is a FunctionBody that begins with a Directive Prologue that contains a Use Strict Directive.

Additionally if you are lost on what features are supported by your current version of Node.js, this node.green can help you (leverages from the same data as kangax).

TLDR:

1. Rebooting both application and DB servers is the quickest fix where data volume, network settings and code haven't changed. We always do so as a rule
2. May be indicator of failing hard-drive that needs replacement - check system notifications

I have often encountered this error for various reasons and have had various solutions, including:

1. refactoring my code to use SqlBulkCopy
2. increasing Timeout values, as stated in various answers or checking for underlying causes (may not be data related)
3. Connection Timeout (Default 15s) - How long it takes to wait for a connection to be established with the SQL server before terminating - TCP/PORT related - can go through a troubleshooting checklist (very handy MSDN article)
4. Command Timeout (Default 30s) - How long it takes to wait for the execution of a query - Query execution/network traffic related - also has a troubleshooting process (another very handy MSDN article)
5. Rebooting of the server(s) - both application & DB Server (if separate) - where code and data haven't changed, environment must have changed - First thing you must do. Typically caused by patches (operating system, .Net Framework or SQL Server patches or updates). Particularly if timeout exception appears as below (even if we do not use Azure):
   • System.Data.Entity.Core.EntityException: An exception has been raised that is likely due to a transient failure. If you are connecting to a SQL Azure database consider using SqlAzureExecutionStrategy. ---> System.Data.Entity.Core.EntityCommandExecutionException: An error occurred while executing the command definition. See the inner exception for details. ---> System.Data.SqlClient.SqlException: A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.) ---> System.ComponentModel.Win32Exception: The semaphore timeout period has expired

Use this JsonKnownTypes, it's very similar way to use, it just add discriminator to json:

[JsonConverter(typeof(JsonKnownTypeConverter<BaseClass>))]
[JsonKnownType(typeof(Base), "base")]
[JsonKnownType(typeof(Derived), "derived")]
public class Base
{
    public string Name;
}
public class Derived : Base
{
    public string Something;
}

Now when you serialize object in json will be add "$type" with "base" and "derived" value and it will be use for deserialize

Serialized list example:

[
    {"Name":"some name", "$type":"base"},
    {"Name":"some name", "Something":"something", "$type":"derived"}
]

If you have a dom object of the ul, use the following.

$('#my_ul').children().length;

A simple example

window.setInterval(function() {_x000D_
  let ul = $('#ul');                 // Get the ul_x000D_
  let length = ul.children().length; // Count of the child nodes._x000D_
_x000D_
  // The show!_x000D_
  ul.append('<li>Item ' + (length + 1) + '</li>');_x000D_
  if (5 <= length) {_x000D_
    ul.empty();_x000D_
    length = -1;_x000D_
  }_x000D_
  $('#ul_length').text(length + 1);_x000D_
}, 1000);

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
_x000D_
<h4>Count of the child nodes: <span id='ul_length'>0</span></h4>_x000D_

Here is good example of the CRUD operation using fetch API:

“A practical ES6 guide on how to perform HTTP requests using the Fetch API” by Dler Ari https://link.medium.com/4ZvwCordCW

Here is the sample code I tried for PATCH or PUT

function update(id, data){
  fetch(apiUrl + "/" + id, {
    method: 'PATCH',
    body: JSON.stringify({
     data
    })
  }).then((response) => {
    response.json().then((response) => {
      console.log(response);
    })
  }).catch(err => {
    console.error(err)
  })

For DELETE:

function remove(id){
  fetch(apiUrl + "/" + id, {
    method: 'DELETE'
  }).then(() => {
     console.log('removed');
  }).catch(err => {
    console.error(err)
  });

Use url instead of path.

from django.conf.urls import url

urlpatterns = [
    url('', views.homepageview, name='home')
]
