Actually it's way easier to use ToolBucket plugin for Notepad++ to multiline replace.

To activate it just go to N++ menu:

Plugins > Plugin Manager > Show Plugin Manager > Check ToolBucket > Install.

Restart N++ and press ALT + SHIFT + F to multiline edit.

Yes, it does. The way to enable this depends on your version of Notepad++. On newer versions you can use:

Menu View ? Show Symbol ? *Show All Characters`

or

Menu View ? Show Symbol ? Show White Space and TAB

(Thanks to bers' comment and bkaid's answers below for these updated locations.)

On older versions you can look for:

Menu View ? Show all characters

or

Menu View ? Show White Space and TAB

In Koltin

Add kotlin extension in your build.gradle.

apply plugin: 'kotlin-android-extensions'

android {
    androidExtensions {
        experimental = true
   }
}

Then create your data class like this.

@Parcelize
data class Sample(val id: Int, val name: String) : Parcelable

Pass Object with Intent

val sample = Sample(1,"naveen")

val intent = Intent(context, YourActivity::class.java)
    intent.putExtra("id", sample)
    startActivity(intent)

Get object with intent

val sample = intent.getParcelableExtra("id")

Whether encrypted be the same when plain text is encrypted with the same key depends of algorithm and protocol. In cryptography there is initialization vector IV: http://en.wikipedia.org/wiki/Initialization_vector that used with various ciphers makes that the same plain text encrypted with the same key gives various cipher texts.

I advice you to read more about cryptography on Wikipedia, Bruce Schneier http://www.schneier.com/books.html and "Beginning Cryptography with Java" by David Hook. The last book is full of examples of usage of http://www.bouncycastle.org library.

If you are interested in cryptography the there is CrypTool: http://www.cryptool.org/ CrypTool is a free, open-source e-learning application, used worldwide in the implementation and analysis of cryptographic algorithms.

Changing the framework to

.NET Framework 4 Client Profile

did the job for me.

Simply add a margin of x amount at the bottom of an item in your RecycleView Adapter.

onCreateViewHolder

LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
                LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT);

layoutParams.setMargins(0, 0, 0, 5);
itemView.setLayoutParams(layoutParams);

As the other answers have said, Spring just takes care of it, creating the beans and injecting them as required.

One of the consequences is that bean injection / property setting might occur in a different order to what your XML wiring files would seem to imply. So you need to be careful that your property setters don't do initialization that relies on other setters already having been called. The way to deal with this is to declare beans as implementing the InitializingBean interface. This requires you to implement the afterPropertiesSet() method, and this is where you do the critical initialization. (I also include code to check that important properties have actually been set.)

json_encode works only with UTF-8 data. You'll have to ensure that your data is in UTF-8. alternatively, you can use iconv() to convert your results to UTF-8 before feeding them to json_encode()

Now, it's easy to do it by enabling/disabling cache option in your ajax request, just like this

$(function () {
    var url = 'your url goes here';
    $('#ajaxButton').click(function (e) {
        $.ajax({
            url: url,
            data: {
                test: 'value'
            },
                cache: true, //cache enabled, false to reverse
                complete: doSomething
            });
        });
    });
    //ToDo after ajax call finishes
    function doSomething(data) {
        console.log(data);
    }
});

This can be done in a much simpler manner now.

$tmpName = $_FILES['csv']['tmp_name'];
$csvAsArray = array_map('str_getcsv', file($tmpName));

This will return you a parsed array of your CSV data. Then you can just loop through it using a foreach statement.

I'm on 64-bit Windows 7 and went to:

https://wxpython.org/

Then downloaded the exe for my system, installed it, and it worked for me.

I wrote the following class to get YouTube video duration using the YouTube API v3 (it returns thumbnails as well):

class Youtube
{
    static $api_key = '<API_KEY>';
    static $api_base = 'https://www.googleapis.com/youtube/v3/videos';
    static $thumbnail_base = 'https://i.ytimg.com/vi/';

    // $vid - video id in youtube
    // returns - video info
    public static function getVideoInfo($vid)
    {
        $params = array(
            'part' => 'contentDetails',
            'id' => $vid,
            'key' => self::$api_key,
        );

        $api_url = Youtube::$api_base . '?' . http_build_query($params);
        $result = json_decode(@file_get_contents($api_url), true);

        if(empty($result['items'][0]['contentDetails']))
            return null;
        $vinfo = $result['items'][0]['contentDetails'];

        $interval = new DateInterval($vinfo['duration']);
        $vinfo['duration_sec'] = $interval->h * 3600 + $interval->i * 60 + $interval->s;

        $vinfo['thumbnail']['default']       = self::$thumbnail_base . $vid . '/default.jpg';
        $vinfo['thumbnail']['mqDefault']     = self::$thumbnail_base . $vid . '/mqdefault.jpg';
        $vinfo['thumbnail']['hqDefault']     = self::$thumbnail_base . $vid . '/hqdefault.jpg';
        $vinfo['thumbnail']['sdDefault']     = self::$thumbnail_base . $vid . '/sddefault.jpg';
        $vinfo['thumbnail']['maxresDefault'] = self::$thumbnail_base . $vid . '/maxresdefault.jpg';

        return $vinfo;
    }
}

Please note that you'll need API_KEY to use the YouTube API:

1. Create a new project here: https://console.developers.google.com/project
2. Enable "YouTube Data API" under "APIs & auth" -> APIs
3. Create a new server key under "APIs & auth" -> Credentials

Similar to @joran's answer. Reshape the df so that the prices for each product are in different columns:

xx <- reshape(df, idvar=c("skew","version","color"),
              v.names="price", timevar="product", direction="wide")

xx will have columns price.p1, ... price.p4, so:

ggp <- ggplot(xx,aes(x=price.p1, y=price.p3, color=factor(skew))) +
       geom_point(shape=19, size=5)
ggp + facet_grid(color~version)

gives the result from your image.

PHP evaluates an empty string to false, so you can simply use:

if (trim($userinput['phoneNumber'])) {
  // validate the phone number
} else {
  echo "Phone number not entered<br/>";
}

Because cron is "stateless", it cannot accurately express "frequencies", only "patterns" which it (apparently) continuously matches against the current time.

Rephrasing your question makes this more obvious: "is it possible to run a cronjob at 00:01am every night except skip nights when it had run within 2 nights?" When cron is comparing the current time to job request time patterns, there's no way cron can know if it ran your job in the past.

(it certainly is possible to write a stateful cron that records past jobs and thus includes patterns for matching against this state, but that's not the standard cron included in most operating systems. Such a system would get complicated by requiring the introduction of the concept of when such patterns "reset". For example, is the pattern reset when the time is changed (i.e. the crontab entry is revised)? Look to your favorite calendar app to see how complicated it can get to express Repeating patterns of scheduled events, and note that they don't have the reset problem because the starting calendar event has a natural "start" a/k/a "reset" date. Try rescheduling an every-other-week recurring calendar event to postpone by a week, over christmas for example. Usually you have to terminate that recurring event and restart a completely new one; this illustrates the limited expressivity of how even complicated calendar apps represent repeating patterns. And of course Calendars have a lot of state-- each individual event can be deleted or rescheduled independently [in most calendar apps]).

Further, you probably want to do your job every 3rd night if successful, but if the last one failed, to try again immediately, perhaps the next night (not wait 3 more days) or even sooner, like an hour later (but stop retrying upon morning's arrival). Clearly, cron couldn't possibly know if your job succeeded and the pattern can't also express an alternate more frequent "retry" schedule.

ANYWAY-- You can do what you want yourself. Write a script, tell cron to run it nightly at 00:01am. This script could check the timestamp of something* which records the "last run", and if it was >3 days ago**, perform the job and reset the "last run" timestamp.

(*that timestamped indicator is a bit of persisted state which you can manipulate and examine, but which cron cannot)

**be careful with time arithmetic if you're using human-readable clock time-- twice a year, some days have 23 or 25 hours in their day, and 02:00-02:59 occurs twice in one day or not at all. Use UTC to avoid this.

I found that running the npm install command in the same directory where your Angular project is, eliminates these warnings. I do not know the reason why.

Specifically, I was trying to use ng2-completer

$ npm install ng2-completer --save
npm WARN saveError ENOENT: no such file or directory, open 'C:\Work\foo\package.json'
npm notice created a lockfile as package-lock.json. You should commit this file.

I was unable to compile. When I tried again, this time in my Angular project directory which was in foo/foo_app, it worked fine.

$ npm install ng2-completer --save

Short answer: mathematically speaking, no, in practical terms, yes, for example for Intentional Programming.

Technically, the answer would be "no, it's not needed" because it's expressible using other constructs. But in practice, I use for i in range(len(a) (or for _ in range(len(a)) if I don't need the index) to make it explicit that I want to iterate as many times as there are items in a sequence without needing to use the items in the sequence for anything.

So: "Is there a need?"? — yes, I need it to express the meaning/intent of the code for readability purposes.

See also: https://en.wikipedia.org/wiki/Intentional_programming

And obviously, if there is no collection that is associated with the iteration at all, for ... in range(len(N)) is the only option, so as to not resort to i = 0; while i < N; i += 1 ...

One important missing bit is, what is the correct way to resolve this issue?

As Greg explained, the root problem here is that a base class constructor would invoke the virtual member before the derived class has been constructed.

The following code, taken from MSDN's constructor design guidelines, demonstrates this issue.

public class BadBaseClass
{
    protected string state;

    public BadBaseClass()
    {
        this.state = "BadBaseClass";
        this.DisplayState();
    }

    public virtual void DisplayState()
    {
    }
}

public class DerivedFromBad : BadBaseClass
{
    public DerivedFromBad()
    {
        this.state = "DerivedFromBad";
    }

    public override void DisplayState()
    {   
        Console.WriteLine(this.state);
    }
}

When a new instance of DerivedFromBad is created, the base class constructor calls to DisplayState and shows BadBaseClass because the field has not yet been update by the derived constructor.

public class Tester
{
    public static void Main()
    {
        var bad = new DerivedFromBad();
    }
}

An improved implementation removes the virtual method from the base class constructor, and uses an Initialize method. Creating a new instance of DerivedFromBetter displays the expected "DerivedFromBetter"

public class BetterBaseClass
{
    protected string state;

    public BetterBaseClass()
    {
        this.state = "BetterBaseClass";
        this.Initialize();
    }

    public void Initialize()
    {
        this.DisplayState();
    }

    public virtual void DisplayState()
    {
    }
}

public class DerivedFromBetter : BetterBaseClass
{
    public DerivedFromBetter()
    {
        this.state = "DerivedFromBetter";
    }

    public override void DisplayState()
    {
        Console.WriteLine(this.state);
    }
}

The secret is simple: Ctrl+Shift+F

Thank you Phil for your solution; in case someone ever gets in the same situation as me, here is a (more complex) variant:

---
# this is just to avoid a call to |default on each iteration
- set_fact:
    postconf_d: {}

- name: 'get postfix default configuration'
  command: 'postconf -d'
  register: command

# the answer of the command give a list of lines such as:
# "key = value" or "key =" when the value is null
- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >
      {{
        postconf_d |
        combine(
          dict([ item.partition('=')[::2]|map('trim') ])
        )
  with_items: command.stdout_lines

This will give the following output (stripped for the example):

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": "hash:/etc/aliases, nis:mail.aliases",
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

Going even further, parse the lists in the 'value':

- name: 'set postfix default configuration as fact'
  set_fact:
    postconf_d: >-
      {% set key, val = item.partition('=')[::2]|map('trim') -%}
      {% if ',' in val -%}
        {% set val = val.split(',')|map('trim')|list -%}
      {% endif -%}
      {{ postfix_default_main_cf | combine({key: val}) }}
  with_items: command.stdout_lines
...

"postconf_d": {
    "alias_database": "hash:/etc/aliases", 
    "alias_maps": [
        "hash:/etc/aliases", 
        "nis:mail.aliases"
    ], 
    "allow_min_user": "no", 
    "allow_percent_hack": "yes"
}

A few things to notice:

• in this case it's needed to "trim" everything (using the >- in YAML and -%} in Jinja), otherwise you'll get an error like:

  FAILED! => {"failed": true, "msg": "|combine expects dictionaries, got u\"  {u'...
  

• obviously the {% if .. is far from bullet-proof

• in the postfix case, val.split(',')|map('trim')|list could have been simplified to val.split(', '), but I wanted to point out the fact you will need to |list otherwise you'll get an error like:

  "|combine expects dictionaries, got u\"{u'...': <generator object do_map at ...
  

Hope this can help.

Sadly even with the likes of CSS 3 we still do not have the likes of :first-word :last-word etc using pure CSS. Thankfully there's almost a JavaScript nowadays for everything which brings me to my recommendation. Using nthEverything and jQuery you can expand from the traditional Pseudo elements.

Currently the valid Pseudos are:

• :first-child
• :first-of-type
• :only-child
• :last-child
• :last-of-type
• :only-of-type
• :nth-child
• :nth-of-type
• :nth-last-child
• :nth-last-of-type

And using nth Everything we can expand this to:

• ::first-letter
• ::first-line
• ::first-word
• ::last-letter
• ::last-line
• ::last-word
• ::nth-letter
• ::nth-line
• ::nth-word
• ::nth-last-letter
• ::nth-last-line
• ::nth-last-word

There are many ways of doing that. If you really want to have a 'hover' class in your A element, then you'd have to do:

a.hover:hover { code here }

Then again, it's uncommon to have such a className there, this is how you do a regular hover:

select:hover { code here }

Here are a few more examples:

1

HTML:

<a class="button" href="#" title="">Click me</a>

CSS:

.button:hover { code here }

2

HTML:

<h1>Welcome</h1>

CSS:

h1:hover { code here }

:hover is one of the many pseudo-classes.

For example you can change, you can control the styling of an element when the mouse hovers over it, when it is clicked and when it was previously clicked.

HTML:

<a class="home" href="#" title="Go back">Go home!</a>

CSS:

.home { color: red; }
.home:hover { color: green; }
.home:active { color: blue; }
.home:visited { color: black; }

Aside the awkward colors I've given as examples, the link with the 'home' class will be red by default, green when the mouse hovers them, blue when they are clicked and black after they were clicked.

Hope this helps

I would use following Guava API: com.google.common.collect.Maps#fromProperties

Properties properties = new Properties();
Map<String, String> map = Maps.fromProperties(properties);

variable=" Hello..."  
print (variable)  
print("This is the Test File "+variable)  

for integer type ...

variable="  10"  
print (variable)  
print("This is the Test File "+str(variable))  

Having used a laptop with BitLocker enabled for almost 2 years now with more or less similar specs (although without the SSD unfortunately), I can say that it really isn't that bad, or even noticable. Although I have not used this particular machine without BitLocker enabled, it really does not feel sluggish at all when compared to my desktop machine (dual core, 16 GB, dual Raptor disks, no BitLocker). Building large projects might take a bit longer, but not enough to notice.

To back this up with more non-scientifical "proof": many of my co-workers used their machines intensively without BitLocker before I joined the company (it became mandatory to use it around the time I joined, even though I am pretty sure the two events are totally unrelated), and they have not experienced noticable performance degradation either.

For me personally, having an "always on" solution like BitLocker beats manual steps for encryption, hands-down. Bitlocker-to-go (new on Windows 7) for USB devices on the other hand is simply too annoying to work with, since you cannot easily exchange information with non-W7 machines. Therefore I use TrueCrypt for removable media.

Conclusion,

to_char works in its own way

So,

Always use this format YYYY-MM-DD for comparison instead of MM-DD-YY or DD-MM-YYYY or any other format

Command works only if "use" -command has been first used to define the database where working in. Table column renaming syntax using DATABASE.TABLE throws error and does not work. Version: HIVE 0.12.

EXAMPLE:

hive> ALTER TABLE databasename.tablename CHANGE old_column_name new_column_name;

  MismatchedTokenException(49!=90)
        at org.antlr.runtime.BaseRecognizer.recoverFromMismatchedToken(BaseRecognizer.java:617)
        at org.antlr.runtime.BaseRecognizer.match(BaseRecognizer.java:115)
        at org.apache.hadoop.hive.ql.parse.HiveParser.alterStatementSuffixExchangePartition(HiveParser.java:11492)
        ...

hive> use databasename;

hive> ALTER TABLE tablename CHANGE old_column_name new_column_name;

OK

You could use a negative look-ahead assertion:

^(?!tbd_).+

Or a negative look-behind assertion:

(^.{1,3}$|^.{4}(?<!tbd_).*)

Or just plain old character sets and alternations:

^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*

You can use the parse method from the URL module in the request callback.

var http = require('http');
var url = require('url');

// Configure our HTTP server to respond with Hello World to all requests.
var server = http.createServer(function (request, response) {
  var queryData = url.parse(request.url, true).query;
  response.writeHead(200, {"Content-Type": "text/plain"});

  if (queryData.name) {
    // user told us their name in the GET request, ex: http://host:8000/?name=Tom
    response.end('Hello ' + queryData.name + '\n');

  } else {
    response.end("Hello World\n");
  }
});

// Listen on port 8000, IP defaults to 127.0.0.1
server.listen(8000);

I suggest you read the HTTP module documentation to get an idea of what you get in the createServer callback. You should also take a look at sites like http://howtonode.org/ and checkout the Express framework to get started with Node faster.

You might find a use for the methods method which returns an array of methods for an object. It's not the same as print_r, but still useful at times.

In SQL Server Management Studio Express:

• Right-click table, choose Modify or Design(For Later Versions)
• Right-click field, choose Indexes/Keys...

• Click Close, Save the table.

git branch --set-upstream <<origin/branch>> is officially not supported anymore and is replaced by git branch --set-upstream-to <<origin/branch>>

The method argument specifies the parameter of the smooth statistic. You can see stat_smooth for the list of all possible arguments to the method argument.

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

The reason you need to use self. is because Python does not use the @ syntax to refer to instance attributes. Python decided to do methods in a way that makes the instance to which the method belongs be passed automatically, but not received automatically: the first parameter of methods is the instance the method is called on. That makes methods entirely the same as functions, and leaves the actual name to use up to you (although self is the convention, and people will generally frown at you when you use something else.) self is not special to the code, it's just another object.

Python could have done something else to distinguish normal names from attributes -- special syntax like Ruby has, or requiring declarations like C++ and Java do, or perhaps something yet more different -- but it didn't. Python's all for making things explicit, making it obvious what's what, and although it doesn't do it entirely everywhere, it does do it for instance attributes. That's why assigning to an instance attribute needs to know what instance to assign to, and that's why it needs self..

The quick answer is to use innerHTML (or prototype's update method which pretty much the same thing). The problem with innerHTML is you need to escape the content being assigned. Depending on your targets you will need to do that with other code OR

in IE:-

document.getElementById("field_name").innerText = newText;

in FF:-

document.getElementById("field_name").textContent = newText;

(Actually of FF have the following present in by code)

HTMLElement.prototype.__defineGetter__("innerText", function () { return this.textContent; })

HTMLElement.prototype.__defineSetter__("innerText", function (inputText) { this.textContent = inputText; })

Now I can just use innerText if you need widest possible browser support then this is not a complete solution but neither is using innerHTML in the raw.

I just wanted to contribute this should someone be looking for help with adding separators between the strings, depending on whether a field is NULL or not.

So in the example of creating a one line address from separate fields

Address1, Address2, Address3, City, PostCode

in my case, I have the following Calculated Column which seems to be working as I want it:

case 
    when [Address1] IS NOT NULL 
    then (((          [Address1]      + 
          isnull(', '+[Address2],'')) +
          isnull(', '+[Address3],'')) +
          isnull(', '+[City]    ,'')) +
          isnull(', '+[PostCode],'')  
end

Hope that helps someone!

You can use FractionallySizedBox

Sometimes decoratedBox doesn't cover the full-screen size. We can fix it by wrapping it with FractionallySizedBox Widget. In this widget we give widthfactor and heightfactor.

The widthfactor shows the [FractionallySizedBox]widget should take _____ percentage of the app's width.

The heightfactor shows the [FractionallySizedBox]widget should take _____ percentage of the app's height.

Example : heightfactor = 0.3 means 30% of app's height. widthfactor = 0.4 means 40% of app's width.

        Hence, for full screen set heightfactor = 1.0 and widthfactor = 1.0

Tip: FractionallySizedBox goes well with the stack widget. So that you can easily add buttons, avatars, texts over your background image in the stack widget whereas in rows and columns you cannot do that.

      home: Scaffold(
        body: SafeArea(
          child: Stack(
            children: <Widget>[
              Container(
                child: FractionallySizedBox(
                  heightFactor: 1.0,
                  widthFactor: 1.0,
                  //for full screen set heightFactor: 1.0,widthFactor: 1.0,
                  child: DecoratedBox(
                    decoration: BoxDecoration(
                      image: DecorationImage(
                        image: AssetImage("images/1.jpg"),
                        fit: BoxFit.fill,
                      ),
                    ),
                  ),

OutPut:

If you don't want your code to depend on other packages, you can always just write these functions:

perm = function(n, x) {
  factorial(n) / factorial(n-x)
}

comb = function(n, x) {
  factorial(n) / factorial(n-x) / factorial(x)
}

Adding to what @Samuel and @bluish did. This is much shorter as the Enum was unnecessary in this case. Plus as an added bonus when the Ascending is the desired result, you can pass only 2 parameters instead of 3 since true is the default answer to the third parameter.

public void Sort<TKey>(ref List<Person> list, Func<Person, TKey> sorter, bool isAscending = true)
{
    list = isAscending ? list.OrderBy(sorter) : list.OrderByDescending(sorter);
}

UltraID3Lib...

Be aware that UltraID3Lib is no longer officially available, and thus no longer maintained. See comments below for the link to a Github project that includes this library

//using HundredMilesSoftware.UltraID3Lib;
UltraID3 u = new UltraID3();
u.Read(@"C:\mp3\song.mp3");
//view
Console.WriteLine(u.Artist);
//edit
u.Artist = "New Artist";
u.Write();

There is part of the spec that sure sounds like this... right in the "flex layout algorithm" and "main sizing" sections:

Otherwise, starting from the first uncollected item, collect consecutive items one by one until the first time that the next collected item would not fit into the flex container’s inner main size, or until a forced break is encountered. If the very first uncollected item wouldn’t fit, collect just it into the line. A break is forced wherever the CSS2.1 page-break-before/page-break-after [CSS21] or the CSS3 break-before/break-after [CSS3-BREAK] properties specify a fragmentation break.

From http://www.w3.org/TR/css-flexbox-1/#main-sizing

It sure sounds like (aside from the fact that page-breaks ought to be for printing), when laying out a potentially multi-line flex layout (which I take from another portion of the spec is one without flex-wrap: nowrap) a page-break-after: always or break-after: always should cause a break, or wrap to the next line.

.flex-container {
  display: flex;
  flex-flow: row wrap;
}

.child {
  flex-grow: 1;
}

.child.break-here {
  page-break-after: always;
  break-after: always;
}

However, I have tried this and it hasn't been implemented that way in...

• Safari (up to 7)
• Chrome (up to 43 dev)
• Opera (up to 28 dev & 12.16)
• IE (up to 11)

It does work the way it sounds (to me, at least) like in:

• Firefox (28+)

Sample at http://codepen.io/morewry/pen/JoVmVj.

I didn't find any other requests in the bug tracker, so I reported it at https://code.google.com/p/chromium/issues/detail?id=473481.

But the topic took to the mailing list and, regardless of how it sounds, that's not what apparently they meant to imply, except I guess for pagination. So there's no way to wrap before or after a particular box in flex layout without nesting successive flex layouts inside flex children or fiddling with specific widths (e.g. flex-basis: 100%).

This is deeply annoying, of course, since working with the Firefox implementation confirms my suspicion that the functionality is incredibly useful. Aside from the improved vertical alignment, the lack obviates a good deal of the utility of flex layout in numerous scenarios. Having to add additional wrapping tags with nested flex layouts to control the point at which a row wraps increases the complexity of both the HTML and CSS and, sadly, frequently renders order useless. Similarly, forcing the width of an item to 100% reduces the "responsive" potential of the flex layout or requires a lot of highly specific queries or count selectors (e.g. the techniques that may accomplish the general result you need that are mentioned in the other answers).

At least floats had clear. Something may get added at some point or another for this, one hopes.

Same as matt said. The "SQL Server(SQLEXPRESS)" was stopped. Enabled it by opening Control Panel > Administrative Tools > Services, right-clicking on the "SQL Server(SQLEXPRESS)" service and selecting "Start" from the available options. Could connect fine after that.

Google Chrome Developer Tools has (a currently experimental) feature called CSS Overview which will allow you to find unused CSS rules.

To enable it follow these steps:

1. Open up DevTools (Command+Option+I on Mac; Control+Shift+I on Windows)
2. Head over to DevTool Settings (Function+F1 on Mac; F1 on Windows)
3. Click open the Experiments section
4. Enable the CSS Overview option

Without seeing your full code, this is impossible to answer with any certainty. The error usually occurs when you are trying to unload a control rather than the form.

Make sure that you don't have the "me" in brackets.

Also if you can post the full code for the userform it would help massively.

If you can convert .xls to .csv before processing, you can use the query below to import the csv to the database:

load data local infile 'FILE.CSV' into table TABLENAME fields terminated by ',' enclosed by '"' lines terminated by '\n' (FIELD1,FIELD2,FIELD3)

SELECT @var = col1,
       @var2 = col2
FROM   Table

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

On your branch - say master, pull and allow unrelated histories

git pull origin master --allow-unrelated-histories

Worked for me.

To fetch single row

$result = $this->getEntityManager()->getConnection()->fetchAssoc($sql)

To fetch all records

$result = $this->getEntityManager()->getConnection()->fetchAll($sql)

Here you can use sql native query, all will work without any issue.

I was getting this same issue, and none of the other answers here helped my particular case.

It turned out to be because my Android Studio project was defaulting to use JDK 8.

Changing this, in the project settings, to point at a JDK 7 installation fixed this for me.

I am using using Ubuntu.

Problem for me solved by using sudo in terminal with the command.

Prologue: If you look up the noun mock in the dictionary you will find that one of the definitions of the word is something made as an imitation.

Mocking is primarily used in unit testing. An object under test may have dependencies on other (complex) objects. To isolate the behavior of the object you want to replace the other objects by mocks that simulate the behavior of the real objects. This is useful if the real objects are impractical to incorporate into the unit test.

In short, mocking is creating objects that simulate the behavior of real objects.

At times you may want to distinguish between mocking as opposed to stubbing. There may be some disagreement about this subject but my definition of a stub is a "minimal" simulated object. The stub implements just enough behavior to allow the object under test to execute the test.

A mock is like a stub but the test will also verify that the object under test calls the mock as expected. Part of the test is verifying that the mock was used correctly.

To give an example: You can stub a database by implementing a simple in-memory structure for storing records. The object under test can then read and write records to the database stub to allow it to execute the test. This could test some behavior of the object not related to the database and the database stub would be included just to let the test run.

If you instead want to verify that the object under test writes some specific data to the database you will have to mock the database. Your test would then incorporate assertions about what was written to the database mock.

Your issue here is that you're not understanding the scope that you're setting.

You are passing the ready function a function itself. Within this function, you're creating another function called codeAddress. This one exists within the scope that created it and not within the window object (where everything and its uncle could call it).

For example:

var myfunction = function(){
    var myVar = 12345;
};

console.log(myVar); // 'undefined' - since it is within 
                    // the scope of the function only.

Have a look here for a bit more on anonymous functions: http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth

Another thing is that I notice you're using jQuery on that page. This makes setting click handlers much easier and you don't need to go into the hassle of setting the 'onclick' attribute in the HTML. You also don't need to make the codeAddress method available to all:

$(function(){
    $("#imgid").click(function(){
        var address = $("#formatedAddress").value;
        geocoder.geocode( { 'address': address}, function(results, status) {
           if (status == google.maps.GeocoderStatus.OK) {
             map.setCenter(results[0].geometry.location);
           }
        });
    });  
});

(You should remove the existing onclick and add an ID to the image element that you want to handle)

Note that I've replaced $(document).ready() with its shortcut of just $() (http://api.jquery.com/ready/). Then the click method is used to assign a click handler to the element. I've also replaced your document.getElementById with the jQuery object.

You have at least these 3 issues:

1. you are not getting the element's value properly
2. The div that you are trying to use to display whether the values have been saved or not has id display yet in your javascript you attempt to get element myDiv which is not even defined in your markup.
3. Never name variables with reserved keywords in javascript. using "string" as a variable name is NOT a good thing to do on most of the languages I can think of. I renamed your string variable to "content" instead. See below.

You can save all three values at once by doing:

var title=new Array();
var names=new Array();//renamed to names -added an S- 
                      //to avoid conflicts with the input named "name"
var tickets=new Array();

function insert(){
    var titleValue = document.getElementById('title').value;
    var actorValue = document.getElementById('name').value;
    var ticketsValue = document.getElementById('tickets').value;
    title[title.length]=titleValue;
    names[names.length]=actorValue;
    tickets[tickets.length]=ticketsValue;
  }

And then change the show function to:

function show() {
  var content="<b>All Elements of the Arrays :</b><br>";
  for(var i = 0; i < title.length; i++) {
     content +=title[i]+"<br>";
  }
  for(var i = 0; i < names.length; i++) {
     content +=names[i]+"<br>";
  }
  for(var i = 0; i < tickets.length; i++) {
     content +=tickets[i]+"<br>";
  }
  document.getElementById('display').innerHTML = content; //note that I changed 
                                                    //to 'display' because that's
                                              //what you have in your markup
}

Here's a jsfiddle for you to play around.

The only problem with cnoremap w!! is that it replaces w with ! (and hangs until you type the next char) whenever you type w! at the : command prompt. Like when you want to actually force-save with w!. Also, even if it's not the first thing after :.

Therefore I would suggest mapping it to something like <Fn>w. I personally have mapleader = F1, so I'm using <Leader>w.

Use the enumerate() function to generate the index along with the elements of the sequence you are looping over:

for index, w in enumerate(loopme):
    print "CURRENT WORD IS", w, "AT CHARACTER", index 

Another way that generalizes more:

df$count <- unsplit(lapply(split(df, df[c("name","type")]), nrow), df[c("name","type")])

As johnnyynnoj mentioned ng-repeat creates a new scope. I would in fact use a function to set the value. See plunker

JS:

$scope.setSelected = function(selected) {
  $scope.selected = selected;
}

HTML:

{{ selected }}

<ul>
  <li ng-class="{current: selected == 100}">
     <a href ng:click="setSelected(100)">ABC</a>
  </li>
  <li ng-class="{current: selected == 101}">
     <a href ng:click="setSelected(101)">DEF</a>
  </li>
  <li ng-class="{current: selected == $index }" 
      ng-repeat="x in [4,5,6,7]">
     <a href ng:click="setSelected($index)">A{{$index}}</a>
  </li>
</ul>

<div  
  ng:show="selected == 100">
  100        
</div>
<div  
  ng:show="selected == 101">
  101        
</div>
<div ng-repeat="x in [4,5,6,7]" 
  ng:show="selected == $index">
  {{ $index }}        
</div>

Try changing the color of your "border-top" attribute to white

I was happy at my textpad and ecplise world until i had to start working with servers running under linux. Remote scripting and set up of config files was needed!

It was hard at the begining but now i can easily set up and tune up my servers.

It's probably worth answering that iPads running iOS 13 will have navigator.platform set to MacIntel, which means you'll need to find another way to detect iPadOS devices.

It's a way of adding text to HTML without it being rendered or normalized.

It's no different than adding it like:

 <textarea style="display:none"><span>{{name}}</span></textarea>

If you do gridview.bind() at:

if(!IsPostBack)

{

//your gridview bind code here...

}

Then you can use DataTable dt = Gridview1.DataSource as DataTable; in function to retrieve datatable.

But I bind the datatable to gridview when i click button, and recording to Microsoft document:

HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests.

If you have same condition, then i will recommend you to use Session to persist the value.

Session["oldData"]=Gridview1.DataSource;

After that you can recall the value when the page postback again.

DataTable dt=(DataTable)Session["oldData"];

Just create hide and show methods yourself for all elements, as follows

Element.prototype.hide = function() {
    this.style.display = 'none';
}
Element.prototype.show = function() {
    this.style.display = '';
}

After this you can use the methods with the usual element identifiers like in these examples:

document.getElementByTagName('div')[3].hide();
document.getElementById('thing').show();

or:

<img src="removeME.png" onclick="this.hide()">

When I need to write short code or a one-liner, I use this "hack":

'Hello World'.replace(/./g, function (char) {
    alert(char);
    return char; // this is optional 
});

This won't count newlines so that can be a good thing or a bad thing. If you which to include newlines, replace: /./ with /[\S\s]/. The other one-liners you may see probably use .split() which has many problems

Abuse leading to a one-expression solution for Matthew's answer:

>>> x = {'a':1, 'b': 2}
>>> y = {'b':10, 'c': 11}
>>> z = (lambda f=x.copy(): (f.update(y), f)[1])()
>>> z
{'a': 1, 'c': 11, 'b': 10}

You said you wanted one expression, so I abused lambda to bind a name, and tuples to override lambda's one-expression limit. Feel free to cringe.

You could also do this of course if you don't care about copying it:

>>> x = {'a':1, 'b': 2}
>>> y = {'b':10, 'c': 11}
>>> z = (x.update(y), x)[1]
>>> z
{'a': 1, 'b': 10, 'c': 11}

For getting the list of ip addresses associated, you can use netstat command

netstat -rn 

This gives a long list of ip addresses and it is not easy to find the required field. The sample result is as following:

Routing tables
Internet:
Destination        Gateway            Flags        Refs      Use   Netif Expire
default            192.168.195.1      UGSc           17        0     en2
127                127.0.0.1          UCS             0        0     lo0
127.0.0.1          127.0.0.1          UH              1   254107     lo0
169.254            link#7             UCS             0        0     en2
192.168.195        link#7             UCS             3        0     en2
192.168.195.1      0:27:22:67:35:ee   UHLWIi         22      397     en2   1193
192.168.195.5      127.0.0.1          UHS             0        0     lo0

More result is truncated.......

The ip address of gateway is in the first line; one with default at its first column.

To display only the selected lines of result, we can use grep command along with netstat

netstat -rn | grep 'default'

This command filters and displays those lines of result having default. In this case, you can see result like following:

default            192.168.195.1      UGSc           14        0     en2

If you are interested in finding only the ip address of gateway and nothing else you can further filter the result using awk. The awk command matches pattern in the input result and displays the output. This can be useful when you are using your result directly in some program or batch job.

netstat -rn | grep 'default' | awk '{print $2}'

The awk command tells to match and print the second column of the result in the text. The final result thus looks like this:

192.168.195.1

In this case, netstat displays all result, grep only selects the line with 'default' in it, and awk further matches the pattern to display the second column in the text.

You can similarly use route -n get default command to get the required result. The full command is

route -n get default | grep 'gateway' | awk '{print $2}'

These commands work well in linux as well as unix systems and MAC OS.

Here is the solution that worked for me. This is a generic function which works for all of the a tags referring to a named a

$("a[href^=#]").on('click', function(event) { 
    event.preventDefault(); 
    var name = $(this).attr('href'); 
    var target = $('a[name="' + name.substring(1) + '"]'); 
    $('html,body').animate({ scrollTop: $(target).offset().top }, 'slow'); 
});

Note 1: Make sure that you use double quotes " in your html. If you use single quotes, change the above part of the code to var target = $("a[name='" + name.substring(1) + "']");

Note 2: In some cases, especially when you use the sticky bar from the bootstrap, the named a will hide beneath the navigation bar. In those cases (or any similar case), you can reduce the number of the pixels from your scroll to achieve the optimal location. For example: $('html,body').animate({ scrollTop: $(target).offset().top - 15 }, 'slow'); will take you to the target with 15 pixels left on the top.

@Redu's solution is a good solution

arrOfObj.map(o => o.isActive = true;) but Array.map still counts as looping through all items.

if you absolutely don't want to have any looping here's a dirty hack :

Object.defineProperty(Object.prototype, "isActive",{
  value: true,
  writable: true,
  configurable: true,
  enumerable: true
});

my advice is not to use it carefully though, it will patch absolutely all javascript Objects (Date, Array, Number, String or any other that inherit Object ) which is really bad practice...

One more thing I found is that some websites uses a platform that checks the User Agent. If the value contains: "HeadlessChrome" the behavior can be weird when using headless mode.

The workaround for that will be to override the user agent value, for example in Java:

chromeOptions.addArguments("--user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.86 Safari/537.36");

I exported my svg from Photoshop CC initially and had to manually add

version="1.1" into the <svg> tag

to get it showing on chrome.

You could do it this way:

-- Notice how STATE got moved inside the condition:
CASE WHEN STATE = 2 AND RetailerProcessType IN (1, 2) THEN '"AUTHORISED"'
     WHEN STATE = 1 AND RetailerProcessType = 2 THEN '"PENDING"'
     ELSE '"DECLINED"'
END

The reason you can do an AND here is that you are not checking the CASE of STATE, but instead you are CASING Conditions.

The key part here is that the STATE condition is a part of the WHEN.

It indeed sets the stack size on a JVM.

You should touch it in either of these two situations:

• StackOverflowError (the stack size is greater than the limit), increase the value
• OutOfMemoryError: unable to create new native thread (too many threads, each thread has a large stack), decrease it.

The latter usually comes when your Xss is set too large - then you need to balance it (testing!)

Maybe too late now, but more often than not you need to run

aspnet_regiis.exe -i  

after installing asp.net. Maybe I would do it anyway now.

Newest version of C# - C# 7.1 allows to create async console app. To enable C# 7.1 in project, you have to upgrade your VS to at least 15.3, and change C# version to C# 7.1 or C# latest minor version. To do this, go to Project properties -> Build -> Advanced -> Language version.

After this, following code will work:

internal class Program
{
    public static async Task Main(string[] args)
    {
         (...)
    }

Here is what seems simplest and works in python 3.7

from collections import OrderedDict

d = OrderedDict([('method', 'constant'), ('data', '1.225')])
d2 = dict(d)  # Now a normal dict

Now to check this:

>>> type(d2)
<class 'dict'>
>>> isinstance(d2, OrderedDict)
False
>>> isinstance(d2, dict)
True

NOTE: This also works, and gives same result -

>>> {**d}
{'method': 'constant', 'data': '1.225'}
>>> {**d} == d2
True

As well as this -

>>> dict(d)
{'method': 'constant', 'data': '1.225'}
>>> dict(d) == {**d}
True

Cheers

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

To me this kind of seemingly simple problem is what Python is all about. Especially if you're coming from a language like C++, where simple text parsing can be a pain in the butt, you'll really appreciate the functionally unit-wise solution that python can give you. I'd keep it really simple with a couple of built-in functions and some generator expressions.

You'll need open(name, mode), myfile.readlines(), mystring.split(), int(myval), and then you'll probably want to use a couple of generators to put them all together in a pythonic way.

# This opens a handle to your file, in 'r' read mode
file_handle = open('mynumbers.txt', 'r')
# Read in all the lines of your file into a list of lines
lines_list = file_handle.readlines()
# Extract dimensions from first line. Cast values to integers from strings.
cols, rows = (int(val) for val in lines_list[0].split())
# Do a double-nested list comprehension to get the rest of the data into your matrix
my_data = [[int(val) for val in line.split()] for line in lines_list[1:]]

Look up generator expressions here. They can really simplify your code into discrete functional units! Imagine doing the same thing in 4 lines in C++... It would be a monster. Especially the list generators, when I was I C++ guy I always wished I had something like that, and I'd often end up building custom functions to construct each kind of array I wanted.

Every method in Web API will return data (JSON) without serialization.

However, in order to return JSON Data in MVC controllers, we will set the returned Action Result type to JsonResult and call the Json method on our object to ensure it is packaged in JSON.

If you're getting source in Content Use the following method

try
{
    var response = restClient.Execute<List<EmpModel>>(restRequest);

    var jsonContent = response.Content;

    var data = JsonConvert.DeserializeObject<List<EmpModel>>(jsonContent);

    foreach (EmpModel item in data)
    {
        listPassingData?.Add(item);
    }
}
catch (Exception ex)
{
    Console.WriteLine($"Data get mathod problem {ex} ");
}

For me the issues was I had multiple clients in my project and I am pretty sure this is perfectly alright, but I deleted all the client for that project and created a new one and all started working for me ( Got this idea fro WP_SMTP plugin help support forum) I am not able to find out that link for reference

com.android.support:support-v4 just recently got update and maybe affect to plugin that use updated version in their dependencies. But if you cannot find in the dependencies (like if you use crosswalk plugin), just put this code in top of your code gradle plugin (no need to add on build.gradle).

configurations.all {
resolutionStrategy.force 'com.android.support:support-v4:24.0.0'
}

Example location to put the code in crosswalk plugin here

Feel free to edit version of com.android.support (DO NOT USE THE 28.0.0) because thats the problem

You could ignore SIGINTs after shutdown starts by calling signal.signal(signal.SIGINT, signal.SIG_IGN) before you start your cleanup code.

Create an new Style with any name, in my case "Theme.Alert.NoActionBar"

<style name="Theme.Alert.NoActionBar" parent="Theme.AppCompat.Dialog">
    <item name="windowNoTitle">true</item>
    <item name="windowActionBar">false</item>
</style>

set its parent as "Theme.AppCompat.Dialog" like in the above code

open AndoridManifest.xml and customize the activity you want to show as Alert Dialog like this

    <activity
        android:excludeFromRecents="true"
        android:theme="@style/Theme.Alert.NoActionBar"
        android:name=".activities.UserLoginActivity" />

in my app i want show my user login activity as Alert Dialog, these are the codes i used. hope this works for you!!!

NULL == NULL -> false (at least in DBMSs)

So you wouldn't be able to retrieve any relationships using a NULL value even with additional columns with real values.

The following code allows you Python 2/3 compatibility:

try:
    reload
except NameError:
    # Python 3
    from imp import reload

The you can use it as reload() in both versions which makes things simpler.

You can now use top level await in Node v13.3.0

import axios from "axios";

const { data } = await axios.get("https://api.namefake.com/");
console.log(data);

run it with --harmony-top-level-await flag

node --harmony-top-level-await index.js

Here's a simplified version with extended explanation for beginners like me who are trying to learn how to put more than one command in one line.

If you were to write out the problem in steps, it would look like this:

// For every file in this directory
// Check the filetype
// If it's an ASCII file, then print out the filename

To achieve this, we can use three UNIX commands: find, file, and grep.

find will check every file in the directory.

file will give us the filetype. In our case, we're looking for a return of 'ASCII text'

grep will look for the keyword 'ASCII' in the output from file

So how can we string these together in a single line? There are multiple ways to do it, but I find that doing it in order of our pseudo-code makes the most sense (especially to a beginner like me).

find ./ -exec file {} ";" | grep 'ASCII'

Looks complicated, but not bad when we break it down:

find ./ = look through every file in this directory. The find command prints out the filename of any file that matches the 'expression', or whatever comes after the path, which in our case is the current directory or ./

The most important thing to understand is that everything after that first bit is going to be evaluated as either True or False. If True, the file name will get printed out. If not, then the command moves on.

-exec = this flag is an option within the find command that allows us to use the result of some other command as the search expression. It's like calling a function within a function.

file {} = the command being called inside of find. The file command returns a string that tells you the filetype of a file. Regularly, it would look like this: file mytextfile.txt. In our case, we want it to use whatever file is being looked at by the find command, so we put in the curly braces {} to act as an empty variable, or parameter. In other words, we're just asking for the system to output a string for every file in the directory.

";" = this is required by find and is the punctuation mark at the end of our -exec command. See the manual for 'find' for more explanation if you need it by running man find.

| grep 'ASCII' = | is a pipe. Pipe take the output of whatever is on the left and uses it as input to whatever is on the right. It takes the output of the find command (a string that is the filetype of a single file) and tests it to see if it contains the string 'ASCII'. If it does, it returns true.

NOW, the expression to the right of find ./ will return true when the grep command returns true. Voila.

We can use TRUNC function in Oracle DB. Here is an example.

SELECT TRUNC(TO_DATE('01 Jan 2018 08:00:00','DD-MON-YYYY HH24:MI:SS')) FROM DUAL

Output: 1/1/2018

Have you tried your own code?
This should work:

SELECT * FROM people WHERE age BETWEEN x AND y

(DateTime.Parse((Eval("date").ToString()))).DayOfWeek.ToString()

at the place of Eval("date"),you can use any date...get name of day

The route-map express example matches url paths with objects which in turn matches http verbs with functions. This lays the routing out in a tree, which is concise and easy to read. The apps's entities are also written as objects with the functions as enclosed methods.

var express = require('../../lib/express')
  , verbose = process.env.NODE_ENV != 'test'
  , app = module.exports = express();

app.map = function(a, route){
  route = route || '';
  for (var key in a) {
    switch (typeof a[key]) {
      // { '/path': { ... }}
      case 'object':
        app.map(a[key], route + key);
        break;
      // get: function(){ ... }
      case 'function':
        if (verbose) console.log('%s %s', key, route);
        app[key](route, a[key]);
        break;
    }
  }
};

var users = {
  list: function(req, res){
    res.send('user list');
  },

  get: function(req, res){
    res.send('user ' + req.params.uid);
  },

  del: function(req, res){
    res.send('delete users');
  }
};

var pets = {
  list: function(req, res){
    res.send('user ' + req.params.uid + '\'s pets');
  },

  del: function(req, res){
    res.send('delete ' + req.params.uid + '\'s pet ' + req.params.pid);
  }
};

app.map({
  '/users': {
    get: users.list,
    del: users.del,
    '/:uid': {
      get: users.get,
      '/pets': {
        get: pets.list,
        '/:pid': {
          del: pets.del
        }
      }
    }
  }
});

app.listen(3000);

I've found that it is best to change the title of the current view controller in the navigation stack to the desired text of the back button before pushing to the next view controller.

For instance

self.navigationItem.title = @"Desired back button text";
[self.navigationController pushViewController:QAVC animated:NO];

Then in the viewDidAppear set the title back to the desired title for the original VC. Voila!

Option 1: Declare a struct with an int and string and return a struct variable.

struct foo {    
 int bar1;
 char bar2[MAX];
};

struct foo fun() {
 struct foo fooObj;
 ...
 return fooObj;
}

Option 2: You can pass one of the two via pointer and make changes to the actual parameter through the pointer and return the other as usual:

int fun(char **param) {
 int bar;
 ...
 strcpy(*param,"....");
 return bar;
}

or

 char* fun(int *param) {
 char *str = /* malloc suitably.*/
 ...
 strcpy(str,"....");
 *param = /* some value */
 return str;
}

Option 3: Similar to the option 2. You can pass both via pointer and return nothing from the function:

void fun(char **param1,int *param2) {
 strcpy(*param1,"....");
 *param2 = /* some calculated value */
}

The solution for your question is:

public static void restartActivity(Activity act){
    Intent intent=new Intent();
    intent.setClass(act, act.getClass());
    ((Activity)act).startActivity(intent);
    ((Activity)act).finish();
}

You need to cast to activity context to start new activity and as well as to finish the current activity.

Hope this helpful..and works for me.

If you are using the less version to compile Bootstrap modify @modal-backdrop-opacity in your variables override file $modal-backdrop-opacity for scss.

Result Set are actually contains multiple rows of data, and use a cursor to point out current position. So in your case, rs4.getString(1) only get you the data in first column of first row. In order to change to next row, you need to call next()

a quick example

while (rs.next()) {
    String sid = rs.getString(1);
    String lid = rs.getString(2);
    // Do whatever you want to do with these 2 values
}

there are many useful method in ResultSet, you should take a look :)

SELECT DISTINCT Salary
FROM emp
ORDER BY salary DESC
LIMIT 1 , 1

This query will give second highest salary of the duplicate records as well.

<p>
    @Html.ActionLink("Create New", "Create")
</p>
@using (Html.BeginForm("Index", "Company", FormMethod.Get))
{
    <p>
        Find by Name: @Html.TextBox("SearchString", ViewBag.CurrentFilter as string)
        <input type="submit" value="Search" />
        <input type="button" value="Clear" onclick="location.href='@Url.Action("Index","Company")'"/>
    </p>
}

In the above example you can see that If I specifically need a button to do some action, I have to do it with @Url.Action whereas if I just want a link I will use @Html.ActionLink. The point is when you have to use some element(HTML) with action url is used.

So you have this code:

<a class="dropdown-toggle" data-toggle="dropdown">Show menu</a>

<ul class="dropdown-menu" role="menu">
    <li>Link 1</li>
    <li>Link 2</li> 
    <li>Link 3</li>                                             
</ul>

Normally it works on click event, and you want it work on hover event. This is very simple, just use this javascript/jquery code:

$(document).ready(function () {
    $('.dropdown-toggle').mouseover(function() {
        $('.dropdown-menu').show();
    })

    $('.dropdown-toggle').mouseout(function() {
        t = setTimeout(function() {
            $('.dropdown-menu').hide();
        }, 100);

        $('.dropdown-menu').on('mouseenter', function() {
            $('.dropdown-menu').show();
            clearTimeout(t);
        }).on('mouseleave', function() {
            $('.dropdown-menu').hide();
        })
    })
})

This works very well and here is the explanation: we have a button, and a menu. When we hover the button we display the menu, and when we mouseout of the button we hide the menu after 100ms. If you wonder why i use that, is because you need time to drag the cursor from the button over the menu. When you are on the menu, the time is reset and you can stay there as many time as you want. When you exit the menu, we will hide the menu instantly without any timeout.

I've used this code in many projects, if you encounter any problem using it, feel free to ask me questions.

I prefer this syntaxis:

$query = "INSERT INTO myTable SET fname='Fname',lname='Lname',website='Website'";

So in general dll has to be placed in two places:

1. GAC ( can have 32 and 64 versions of dll's)
2. your project bin folder

Thus, you just need add reference to log4net.dll. (In your case 32-bit with PublicKeyToken=692fbea5521e1304)

You can achive that by

• downloading log4net.dll separately and add reference to it
• dowloading SAP crystal report SDK (32 bit) https://wiki.scn.sap.com/wiki/display/BOBJ/Crystal+Reports%2C+Developer+for+Visual+Studio+Downloads

from __future__ import with_statement
with open('file.txt','r+') as f:
    counter = str(int(f.read().strip())+1)
    f.seek(0)
    f.write(counter)

You can write your For loop to individually store dataframes from a list:

allocation = list()

for(i in 1:length(allocation)){
    write.csv(data.frame(allocation[[i]]), file = paste0(path, names(allocation)[i], '.csv'))
}

bool isFirst = compareString.Contains(firstString);
bool isSecond = compareString.Contains(secondString );

@find /v "@" < %0 | sqlplus -s scott/tiger@orcl & goto :eof

select sysdate from dual;

function getMethods(obj)
{
    var res = [];
    for(var m in obj) {
        if(typeof obj[m] == "function") {
            res.push(m)
        }
    }
    return res;
}

Well, technically speaking we can pass a parameter to a computed function, the same way we can pass a parameter to a getter function in vuex. Such a function is a function that returns a function.

For instance, in the getters of a store:

{
  itemById: function(state) {
    return (id) => state.itemPool[id];
  }
}

This getter can be mapped to the computed functions of a component:

computed: {
  ...mapGetters([
    'ids',
    'itemById'
  ])
}

And we can use this computed function in our template as follows:

<div v-for="id in ids" :key="id">{{itemById(id).description}}</div>

We can apply the same approach to create a computed method that takes a parameter.

computed: {
  ...mapGetters([
    'ids',
    'itemById'
  ]),
  descriptionById: function() {
    return (id) => this.itemById(id).description;
  }
}

And use it in our template:

<div v-for="id in ids" :key="id">{{descriptionById(id)}}</div>

This being said, I'm not saying here that it's the right way of doing things with Vue.

However, I could observe that when the item with the specified ID is mutated in the store, the view does refresh its contents automatically with the new properties of this item (the binding seems to be working just fine).

You are not creating a separate dictionary for each iframe, you just keep modifying the same dictionary over and over, and you keep adding additional references to that dictionary in your list.

Remember, when you do something like content.append(info), you aren't making a copy of the data, you are simply appending a reference to the data.

You need to create a new dictionary for each iframe.

for iframe in soup.find_all('iframe'):
   info = {}
    ...

Even better, you don't need to create an empty dictionary first. Just create it all at once:

for iframe in soup.find_all('iframe'):
    info = {
        "src":    iframe.get('src'),
        "height": iframe.get('height'),
        "width":  iframe.get('width'),
    }
    content.append(info)

There are other ways to accomplish this, such as iterating over a list of attributes, or using list or dictionary comprehensions, but it's hard to improve upon the clarity of the above code.

You can increase the timeout in node like so.

app.post('/slow/request', function(req, res){ req.connection.setTimeout(100000); //100 seconds ... }

And this is if copying a single property to another list is needed:

targetList.AddRange(sourceList.Select(i => i.NeededProperty));

This is just an example based on Ned Batchelder's explanation.

__getattr__ example:

class Foo(object):
    def __getattr__(self, attr):
        print "looking up", attr
        value = 42
        self.__dict__[attr] = value
        return value

f = Foo()
print f.x 
#output >>> looking up x 42

f.x = 3
print f.x 
#output >>> 3

print ('__getattr__ sets a default value if undefeined OR __getattr__ to define how to handle attributes that are not found')

And if same example is used with __getattribute__ You would get >>> RuntimeError: maximum recursion depth exceeded while calling a Python object

Here's a working version. I changed the XmlElementAttribute labels to XmlElement because in the xml the StockNumber, Make and Model values are elements, not attributes. Also I removed the reader.ReadToEnd(); (that function reads the whole stream and returns a string, so the Deserialize() function couldn't use the reader anymore...the position was at the end of the stream). I also took a few liberties with the naming :).

Here are the classes:

[Serializable()]
public class Car
{
    [System.Xml.Serialization.XmlElement("StockNumber")]
    public string StockNumber { get; set; }

    [System.Xml.Serialization.XmlElement("Make")]
    public string Make { get; set; }

    [System.Xml.Serialization.XmlElement("Model")]
    public string Model { get; set; }
}


[Serializable()]
[System.Xml.Serialization.XmlRoot("CarCollection")]
public class CarCollection
{
    [XmlArray("Cars")]
    [XmlArrayItem("Car", typeof(Car))]
    public Car[] Car { get; set; }
}

The Deserialize function:

CarCollection cars = null;
string path = "cars.xml";

XmlSerializer serializer = new XmlSerializer(typeof(CarCollection));

StreamReader reader = new StreamReader(path);
cars = (CarCollection)serializer.Deserialize(reader);
reader.Close();

And the slightly tweaked xml (I needed to add a new element to wrap <Cars>...Net is picky about deserializing arrays):

<?xml version="1.0" encoding="utf-8"?>
<CarCollection>
<Cars>
  <Car>
    <StockNumber>1020</StockNumber>
    <Make>Nissan</Make>
    <Model>Sentra</Model>
  </Car>
  <Car>
    <StockNumber>1010</StockNumber>
    <Make>Toyota</Make>
    <Model>Corolla</Model>
  </Car>
  <Car>
    <StockNumber>1111</StockNumber>
    <Make>Honda</Make>
    <Model>Accord</Model>
  </Car>
</Cars>
</CarCollection>

Use The Constructor.newInstance method. The Class.newInstance method has been deprecated since Java 9 to enhance compiler recognition of instantiation exceptions.

public class Foo<T> {   
    public Foo()
    {
        Class<T> newT = null; 
        instantiateNew(newT);
    }

    T instantiateNew(Class<?> clsT)
    {
        T newT;
        try {

Because your program now contains two copies of the foo function, once inside foo.cpp and once inside main.cpp

Think of #include as an instruction to the compiler to copy/paste the contents of that file into your code, so you'll end up with a processed main.cpp that looks like this

#include <iostream> // actually you'll get the contents of the iostream header here, but I'm not going to include it!
int foo(int a){
    return ++a;
}

int main(int argc, char *argv[])
{
int x=42;
std::cout << x <<std::endl;
std::cout << foo(x) << std::endl;
return 0;
}

and foo.cpp

int foo(int a){
    return ++a;
}

hence the multiple definition error

I created dummy sample for Google Maps v2 Android with Kotlin and AndroidX

You can find complete project here: github-link

The property 'length' returns the (last_key + 1) for arrays with numeric keys:

var  nums  =  new  Array ();
nums [ 10 ]  =  10 ; 
nums [ 11 ]  =  11 ;
log.info( nums.length );

will print 12!

This will work:

var  nums  =  new  Array ();
nums [ 10 ]  =  10 ; 
nums [ 11 ]  =  11 ;
nums [ 12 ]  =  12 ;
log.info( nums.length + '  /  '+ Object.keys(nums).length );

Like that:

SELECT p.*, a.street, a.city FROM persons AS p
JOIN address AS a ON p.id = a.person_id
WHERE a.zip = '97299'

It is possible to edit same file in Split mode. It is best explained in following youtube video.

https://www.youtube.com/watch?v=q2cMEeE1aOk

Simply with command line:

javac MyApp.java
jar -cf myJar.jar MyApp.class

Sure IDEs avoid using command line terminal

$(document).ready(function() {
    // Check if body height is higher than window height :)
    if ($("body").height() > $(window).height()) {
        alert("Vertical Scrollbar! D:");
    }

    // Check if body width is higher than window width :)
    if ($("body").width() > $(window).width()) {
        alert("Horizontal Scrollbar! D:<");
    }
});

You might want to remove the accents and diacritic signs first, then on each character position check if the "simplified" string is an ascii letter - if it is, the original position shall contain word characters, if not, it can be removed.

I had the same issue, and the answer was in the dmenu source code: the stest utility made for that purpose. You can compile the 'stest.c' and 'arg.h' files and it should work. There is a man page for the usage, that I put there for convenience:

STEST(1)         General Commands Manual         STEST(1)

NAME
       stest - filter a list of files by properties

SYNOPSIS
       stest  [-abcdefghlpqrsuwx]  [-n  file]  [-o  file]
       [file...]

DESCRIPTION
       stest takes a list of files  and  filters  by  the
       files'  properties,  analogous  to test(1).  Files
       which pass all tests are printed to stdout. If  no
       files are given, stest reads files from stdin.

OPTIONS
       -a     Test hidden files.

       -b     Test that files are block specials.

       -c     Test that files are character specials.

       -d     Test that files are directories.

       -e     Test that files exist.

       -f     Test that files are regular files.

       -g     Test  that  files  have  their set-group-ID
              flag set.

       -h     Test that files are symbolic links.

       -l     Test the contents of a directory  given  as
              an argument.

       -n file
              Test that files are newer than file.

       -o file
              Test that files are older than file.

       -p     Test that files are named pipes.

       -q     No  files are printed, only the exit status
              is returned.

       -r     Test that files are readable.

       -s     Test that files are not empty.

       -u     Test that files have their set-user-ID flag
              set.

       -v     Invert  the  sense  of  tests, only failing
              files pass.

       -w     Test that files are writable.

       -x     Test that files are executable.

EXIT STATUS
       0      At least one file passed all tests.

       1      No files passed all tests.

       2      An error occurred.

Best guess is you are on windows and your line ending settings are set for windows. See this topic: How to change line-ending settings

or use:

tr '\r\n' ' '

You are missing setting what field is the Text and Value in the SelectList itself. That is why it does a .ToString() on each object in the list. You could think that given it is a list of SelectListItem it should be smart enough to detect this... but it is not.

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Selected = true, Text = string.Empty, Value = "-1"},
        new SelectListItem { Selected = false, Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Selected = false, Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text", 1);

BTW, you can use a list of array of any type... and then just set the name of the properties that will act as Text and Value.

I think it is better to do it like this:

u.UserTypeOptions = new SelectList(
    new List<SelectListItem>
    {
        new SelectListItem { Text = "Homeowner", Value = ((int)UserType.Homeowner).ToString()},
        new SelectListItem { Text = "Contractor", Value = ((int)UserType.Contractor).ToString()},
    }, "Value" , "Text");

I removed the -1 item, and the setting of each items selected true/false.

Then, in your view:

@Html.DropDownListFor(m => m.UserType, Model.UserTypeOptions, "Select one")

This way, if you set the "Select one" item, and you don't set one item as selected in the SelectList, the UserType will be null (the UserType need to be int? ).

If you need to set one of the SelectList items as selected, you can use:

u.UserTypeOptions = new SelectList(options, "Value" , "Text", userIdToBeSelected);

Here is how I made monthly page in similar manner as Fernando:

1. I wrote manually on each page number of the month and named that place as ThisMonth. Note that you can do this only before you make copies of the sheet. After copying Excel doesn't allow you to use same name, but with sheet copy it does it still. This solution works also without naming.
2. I added number of weeks in the month to location C12. Naming is fine also.

3. I made five weeks on every page and on fifth week I made function

     =IF(C12=5,DATE(YEAR(B48),MONTH(B48),DAY(B48)+7),"")
   

   that empties fifth week if this month has only four weeks. C12 holds the number of weeks.

4. ...
5. I created annual Excel, so I had 12 sheets in it: one for each month. In this example name of the sheet is "Month". Note that this solutions works also with the ODS file standard except you need to change all spaces as "_" characters.
6. I renamed first "Month" sheet as "Month (1)" so it follows the same naming principle. You could also name it as "Month1" if you wish, but "January" would require a bit more work.

7. Insert following function on the first day field starting sheet #2:

    =INDIRECT(CONCATENATE("'Month (",ThisMonth-1,")'!B15"))+INDIRECT(CONCATENATE("'Month (",ThisMonth-1,")'!C12"))*7
   

   So in another word, if you fill four or five weeks on the previous sheet, this calculates date correctly and continues from correct date.

Simply put:

SELECT * 
FROM TABLE_NAME
WHERE
dob > '1/21/2012'

Where 1/21/2012 is the date and you want all data, including that date.

SELECT * 
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'

Use a between if you're selecting time between two dates

The other answers did not help me as I only had client attached (the previous one that started the session was already detached).

To fix it I followed the answer here (I was not using xterm).

Which simply said:

1. Detach from tmux session
2. Run resize linux command
3. Reattach to tmux session

How about this:

$(this).css('background-color', '#FFFFFF');

You may need to config the CORS at Spring Boot side. Please add below class in your Project.

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.CorsRegistry;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

@Configuration
@EnableWebMvc
public class WebConfig implements Filter,WebMvcConfigurer {



    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**");
    }

    @Override
    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) {
      HttpServletResponse response = (HttpServletResponse) res;
      HttpServletRequest request = (HttpServletRequest) req;
      System.out.println("WebConfig; "+request.getRequestURI());
      response.setHeader("Access-Control-Allow-Origin", "*");
      response.setHeader("Access-Control-Allow-Methods", "POST, PUT, GET, OPTIONS, DELETE");
      response.setHeader("Access-Control-Allow-Headers", "Content-Type, Access-Control-Allow-Headers, Authorization, X-Requested-With,observe");
      response.setHeader("Access-Control-Max-Age", "3600");
      response.setHeader("Access-Control-Allow-Credentials", "true");
      response.setHeader("Access-Control-Expose-Headers", "Authorization");
      response.addHeader("Access-Control-Expose-Headers", "responseType");
      response.addHeader("Access-Control-Expose-Headers", "observe");
      System.out.println("Request Method: "+request.getMethod());
      if (!(request.getMethod().equalsIgnoreCase("OPTIONS"))) {
          try {
              chain.doFilter(req, res);
          } catch(Exception e) {
              e.printStackTrace();
          }
      } else {
          System.out.println("Pre-flight");
          response.setHeader("Access-Control-Allow-Origin", "*");
          response.setHeader("Access-Control-Allow-Methods", "POST,GET,DELETE,PUT");
          response.setHeader("Access-Control-Max-Age", "3600");
          response.setHeader("Access-Control-Allow-Headers", "Access-Control-Expose-Headers"+"Authorization, content-type," +
          "USERID"+"ROLE"+
                  "access-control-request-headers,access-control-request-method,accept,origin,authorization,x-requested-with,responseType,observe");
          response.setStatus(HttpServletResponse.SC_OK);
      }

    }

}

UPDATE:

To append Token to each request you can create one Interceptor as below.

import { Injectable } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';

@Injectable()
export class AuthInterceptor implements HttpInterceptor {

  intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
    const token = window.localStorage.getItem('tokenKey'); // you probably want to store it in localStorage or something


    if (!token) {
      return next.handle(req);
    }

    const req1 = req.clone({
      headers: req.headers.set('Authorization', `${token}`),
    });

    return next.handle(req1);
  }

}

Example

You can use the following code which is given below;

Collections.sort(list, Collections.reverseOrder());

or if you are going to use custom comparator you can use as it is given below

Collections.sort(list, Collections.reverseOrder(new CustomComparator());

Where CustomComparator is a comparator class that compares the object which is present in the list.

Please do This code - it worked

 AbstractApplicationContext context= new ClassPathXmlApplicationContext("spring-config.xml");

o/w: Delete main method class and recreate it while recreating please uncheck Inherited abstract method its worked

The timeout configuration needs to be set at the client level, so the configuration I was setting in the web.config had no effect, the WCF test tool has its own configuration and there is where you need to set the timeout.

I don't know if you can change the size at runtime but you can allocate the size at runtime. Try using this code:

class MyClass {
    void myFunction () {
        Scanner s = new Scanner (System.in);
        int myArray [];
        int x;

        System.out.print ("Enter the size of the array: ");
        x = s.nextInt();

        myArray = new int[x];
    }
}

this assigns your array size to be the one entered at run time into x.

size_t should be defined in your standard library's headers. In my experience, it usually is simply a typedef to unsigned int. The point, though, is that it doesn't have to be. Types like size_t allow the standard library vendor the freedom to change its underlying data types if appropriate for the platform. If you assume size_t is always unsigned int (via casting, etc), you could run into problems in the future if your vendor changes size_t to be e.g. a 64-bit type. It is dangerous to assume anything about this or any other library type for this reason.

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' 
    IDENTIFIED BY 'YOUR_PASS' 
    WITH GRANT OPTION;
FLUSH PRIVILEGES;  

*.* = DB.TABLE you can restrict user to specific database and specific table.

'root'@'%' you can change root with any user you created and % is to allow all IP. You can restrict it by changing %.168.1.1 etc too.

If that doesn't resolve, then also modify my.cnf or my.ini and comment these lines

bind-address = 127.0.0.1 to #bind-address = 127.0.0.1
and
skip-networking to #skip-networking

• Restart MySQL and repeat above steps again.

Raspberry Pi, I found bind-address configuration under \etc\mysql\mariadb.conf.d\50-server.cnf

I believe you have to constraint T with a where statement to only allow objects with a new constructor.

RIght now it accepts anything including objects without it.

public static boolean isPalindrome(String in){
   if(in.equals(" ") || in.length() < 2 ) return true;
   if(in.charAt(0).equalsIgnoreCase(in.charAt(in.length-1))
      return isPalindrome(in.substring(1,in.length-2));
   else
      return false;
 }

Maybe you need something like this. Not tested, I'm not sure about string indexes, but it's a start point.

Logs can be removed using bash in linux and sed:

find . -name "*\.java" | xargs sed -ri ':a; s%Log\.[ivdwe].*\);%;%; ta; /Log\.[ivdwe]/ !b; N; ba'

Works for multiline logs. In this solution you can be sure, that logs are not present in production code.

Extending @oopbase's answer with return; statement.

Let's consider a use case of traditional authentication system where we store login information into the session. On each page we check for active session like,

/* Some Import Statements here. */

if(null == session || !session.getAttribute("is_login").equals("1")) {
    response.sendRedirect("http://domain.com/login");
}

// ....

session.getAttribute("user_id");

// ....
/* Some More JSP+Java+HTML code here */

It looks fine at first glance however; It has one issue. If your server has expired session due to time limit and user is trying to access the page he might get error if you have not written your code in try..catch block or handled if(null != session.getAttribute("attr_name")) everytime.

So by putting a return; statement I stopped further execution and forced to redirect page to certain location.

if(null == session || !session.getAttribute("is_login").equals("1")) {
    response.sendRedirect("http://domain.com/login");
    return;
}

Note that Use of redirection may vary based on the requirements. Nowadays people don't use such authentication system. (Modern approach - Token Based Authentication) It's just an simple example to understand where and how to place redirection(s).

With Firefox, Safari (and other Gecko based browsers) you can easily use textarea.selectionStart, but for IE that doesn't work, so you will have to do something like this:

function getCaret(node) {
  if (node.selectionStart) {
    return node.selectionStart;
  } else if (!document.selection) {
    return 0;
  }

  var c = "\001",
      sel = document.selection.createRange(),
      dul = sel.duplicate(),
      len = 0;

  dul.moveToElementText(node);
  sel.text = c;
  len = dul.text.indexOf(c);
  sel.moveStart('character',-1);
  sel.text = "";
  return len;
}

(complete code here)

I also recommend you to check the jQuery FieldSelection Plugin, it allows you to do that and much more...

Edit: I actually re-implemented the above code:

function getCaret(el) { 
  if (el.selectionStart) { 
    return el.selectionStart;

Overall:You persist entity that is violating database rules like as saving entity that has varchar field over 250 chars ,something like that.

In my case it was a squishy problem with TestEntityManager ,because it use HSQL database /in memory database/ and it persist the user but when you try to find it ,it drops the same exception :/

@RunWith(SpringRunner.class)
@ContextConfiguration(classes= Application.class)
@DataJpaTest
@ActiveProfiles("test")
public class UserServicesTests {

@Autowired
private TestEntityManager testEntityManager;

@Autowired
private UserRepository userRepository;

@Test
public void oops() {
    User user = new User();
    user.setUsername("Toshko");
    //EMAIL IS REQUIRED:
    //user.setEmail("OPS");
    this.testEntityManager.persist(user);

    //HERE COMES TE EXCEPTION BECAUSE THE EMAIL FIELD IN TE DATABASE IS REQUIRED :
    this.userRepository.findUserByUsername("Toshko");

    System.out.println();
}
}

just for fun, valid rectangles and assuming that m[0] exists

>>> m = [[1,2,3],[4,5,6],[7,8,9]]
>>> [[row[i] for row in m] for i in range(len(m[0]))]
[[1, 4, 7], [2, 5, 8], [3, 6, 9]]

I believe this will solve the issue

var z = '[{"name":"1","age":"2"},{"name":"1","age":"3"}]';
z = JSON.stringify(JSON.parse(z));
$.ajax({
    url: "/setTest",
    data: z,
    type: "POST",
    dataType:"json",
    contentType:'application/json'               
});

I don't think there's a standard as to the location of the sitemap. That's the reason why you should specify an arbitrary URL to your sitemap when you're adding one using Google's Webmaster Tools.

Suppose you want the value of the first item.

ListBox list = new ListBox();
Console.Write(list.Items[0].Value);

Your missing a ' after night. right here getElementById('Night

Hopefully I am not misunderstanding this document, but if your using Java 1.8, in theory, you could accomplish something like this by defining a working implementation of a default method ("defender methods") within an interface that you implement.

interface DoInterface {
    void doNothing();
    public default void remove() {
       throw new UnsupportedOperationException("remove");
    }
    public default int doSomething( int arg1, int arg2) {
        val = arg1 + arg2 * arg1;
        log( "Value is: " + val );
        return val;
    }
}
class DoIt extends DoInterface {
    DoIt() {
        log("Called DoIt constructor.");
    }
    public int doSomething() {
        int val = doSomething( 0, 100 );
        return val;
    }
}

Then, call it either way:

DoIt d = new DoIt();
d.doSomething();
d.soSomething( 5, 45 );

If you have to find the difference between originalDate and today’s date, Here is a reliable algorithm without so many condition checks.

1. Declare a intermediateDate variable and initialize to the originalDate
2. Find difference between years.(yearDiff)
3. Add yearDiff to intermediateDate and check whether the value is greater than today’s date.
4. If newly obtained intermediateDate > today’s date adjust the yearDiff and intermediateDate by one.
5. Continue above steps for month and Days.

I have used System.Data.Linq functions to do find the year, month and day differences. Please find c# code below

        DateTime todaysDate = DateTime.Now;
        DateTime interimDate = originalDate;

        ///Find Year diff
        int yearDiff = System.Data.Linq.SqlClient.SqlMethods.DateDiffYear(interimDate, todaysDate);
        interimDate = interimDate.AddYears(yearDiff);
        if (interimDate > todaysDate)
        {
            yearDiff -= 1;
            interimDate = interimDate.AddYears(-1);
        }

        ///Find Month diff
        int monthDiff = System.Data.Linq.SqlClient.SqlMethods.DateDiffMonth(interimDate, todaysDate);
        interimDate = interimDate.AddMonths(monthDiff);
        if (interimDate > todaysDate)
        {
            monthDiff -= 1;
            interimDate = interimDate.AddMonths(-1);
        }

        ///Find Day diff
        int daysDiff = System.Data.Linq.SqlClient.SqlMethods.DateDiffDay(interimDate, todaysDate);

Try to make your javascript unobtrusive :

• you should use a real link in href attribute
• and add a listener on click event to handle ajax

Add:

in your php.ini file. If you are using shared hosting, create one first.

Yes! Abstract classes can have constructors!

Yes, when we define a class to be an Abstract Class it cannot be instantiated but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.

When we create an object of any subclass all the constructors in the corresponding inheritance tree are invoked in the top to bottom approach. The same case applies to abstract classes. Though we cannot create an object of an abstract class, when we create an object of a class which is concrete and subclass of the abstract class, the constructor of the abstract class is automatically invoked. Hence we can have a constructor in abstract classes.

Note: A non-abstract class cannot have abstract methods but an abstract class can have a non-abstract method. Reason is similar to that of constructors, difference being instead of getting invoked automatically we can call super(). Also, there is nothing like an abstract constructor as it makes no sense at all.

This error can also occur if you are not following the marco rules

Like

#define 1K 1024 // Macro rules must be identifiers error occurs

Reason: Macro Should begin with a letter, not a number

Change to

#define ONE_KILOBYTE 1024 // This resolves 

The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.

Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE

See the following example for how to make it work:

# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")

# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)

# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe 
##   1  22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic 
## 333   1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
## 
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe 
##  22   1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac 
##  22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
##     tac nothere 
##    TRUE   FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
##  tac test 
##   22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
##   tac  test 
##    22 54321

Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can

I hear your pain. I'm going through this right now (years later). From what I've learned, you can think of RTSP as a "VCR controller", the protocol allows you to specify which streams (presentations) you want to play, it will then send you a description of the media, and then you can use RTSP to play, stop, pause, and record the remote stream. The media itself goes over RTP. RTSP is normally implemented over a different socket or communication layer. Although it is simply a protocol, most often it's implemented by a server over a socket. For live streams, the RTSP stream you request is simply a name of a stream. It doesn't need to refer to a file on the server, the server's RTSP implementation can parse that stream, put together a live graph, and then provide the SDP (description) for that stream name. But, this is of course specific to the way the RTSP server has been implemented. For "live" streams, it's probably simpler to just use RTP, but you'll need a way to transfer the SDP from the RTP server to the client that wants to play that stream.

Same issue on Server 2016, IIS 10, 500.19 error. I installed the redirect module and it worked. I do not know why this was not included by default.

https://www.iis.net/downloads/microsoft/url-rewrite#additionalDownloads

To be clear it looks like the web.config from IIS 7 will work, or is designed to work, but the lack of this module gives the really odd and unhelpful error. Googling takes you to a Microsoft page which insists that your site is corrupted or your web.config is corrupted. Neither seems to be the case.

That unhelpful page is here: https://support.microsoft.com/en-us/kb/942055

You can also use a class object directly; it creates a namespace:

class a: pass
a.somefield1 = 'somevalue1'
setattr(a, 'somefield2', 'somevalue2')

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

To answer "why" someone might use it, I was tempted to use it since I had the $_POST values stored after the page refresh or while going from one page to another. My sense tells me this is not a good practice, but it works nevertheless.

The new filtering feature in Servlet 2.4 basically alleviates the restriction that filters can only operate in the request flow before and after the actual request processing by the application server. Instead, Servlet 2.4 filters can now interact with the request dispatcher at every dispatch point. This means that when a Web resource forwards a request to another resource (for instance, a servlet forwarding the request to a JSP page in the same application), a filter can be operating before the request is handled by the targeted resource. It also means that should a Web resource include the output or function from other Web resources (for instance, a JSP page including the output from multiple other JSP pages), Servlet 2.4 filters can work before and after each of the included resources. .

To turn on that feature you need:

web.xml

<filter>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> 
</filter>  
<filter-mapping>   
    <filter-name>springSecurityFilterChain</filter-name>   
    <url-pattern>/<strike>*</strike></url-pattern>
    <dispatcher>REQUEST</dispatcher>
    <dispatcher>FORWARD</dispatcher>
</filter-mapping>

RegistrationController

return "forward:/login?j_username=" + registrationModel.getUserEmail()
        + "&j_password=" + registrationModel.getPassword();

I use this:

template <typename T>
bool fromHex(const std::string& hexValue, T& result)
{
    std::stringstream ss;
    ss << std::hex << hexValue;
    ss >> result;

    return !ss.fail();
}

The relevel() command is a shorthand method to your question. What it does is reorder the factor so that whatever is the ref level is first. Therefore, reordering your factor levels will also have the same effect but gives you more control. Perhaps you wanted to have levels 3,4,0,1,2. In that case...

bFactor <- factor(b, levels = c(3,4,0,1,2))

I prefer this method because it's easier for me to see in my code not only what the reference was but the position of the other values as well (rather than having to look at the results for that).

NOTE: DO NOT make it an ordered factor. A factor with a specified order and an ordered factor are not the same thing. lm() may start to think you want polynomial contrasts if you do that.

  Gson gson = new Gson();
                Type listType = new TypeToken<List<Data>>() {}.getType();
                List<Data>     cartProductList = gson.fromJson(response.body().get("data"), listType);
                Toast.makeText(getContext(), ""+cartProductList.get(0).getCity(), Toast.LENGTH_SHORT).show();

There is no more efficient way, if all you have is the iterator. And if the iterator can only be used once, then getting the count before you get the iterator's contents is ... problematic.

The solution is either to change your application so that it doesn't need the count, or to obtain the count by some other means. (For example, pass a Collection rather than Iterator ...)

1.To scroll page to the bottom use window.scrollTo(0,document.body.scrollHeight) as parameter

//Code to navigate to bottom

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollHeight));

2.To scroll page to the top use window.scrollTo(0,document.body.scrollTop) as parameter

//Code to navigate to top

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollTop));

3.To scroll page to the Left use window.scrollTo(0,document.body.scrollLeft) as parameter

//Code to navigate to left

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,document.body.scrollLeft));

4.To scroll to certain point window.scrollTo(0,500) as parameter

//Code to navigate to certain point e.g. 500 is passed as value here

WebDriver driver = new ChromeDriver();
JavascriptExecutor jsExecuter = (JavascriptExecutor)driver;
jsExecuter.executeScript(window.scrollTo(0,500));

To check the navigation directly in browser , open developers tool in browser and navigate to console. Execute the command on console window.scrollTo(0,400)

Do what Kelly said...

BUT. Instead of having the input positioned absolute and top -20px (just hiding it off the page), make the input box hidden.

example:

<input type="checkbox" hidden> 

Works better and can put it anywhere on the page.

Just catch your exception and do proper exception handling:

if (cost !=null && !"".equals(cost) ){
        try {
           Integer intCost = Integer.parseInt(cost);
           List<Book> books = bookService . findBooksCheaperThan(intCost);  
        } catch (NumberFormatException e) {
           System.out.println("This is not a number");
           System.out.println(e.getMessage());
        }
    }

The distinction between a bare and non-bare Git repository is artificial and misleading since a workspace is not part of the repository and a repository doesn't require a workspace. Strictly speaking, a Git repository includes those objects that describe the state of the repository. These objects may exist in any directory, but typically exist in the .git directory in the top-level directory of the workspace. The workspace is a directory tree that represents a particular commit in the repository, but it may exist in any directory or not at all. Environment variable $GIT_DIR links a workspace to the repository from which it originates.

Git commands git clone and git init both have options --bare that create repositories without an initial workspace. It's unfortunate that Git conflates the two separate, but related concepts of workspace and repository and then uses the confusing term bare to separate the two ideas.

If you don't want to use the class method you can use parent-child method to make changes in the text box.

For eg. I've made a form in my form div.

HTML Code:

<div class="form">
    <textarea name="message" rows="10" cols="30" >Describe your project in detail.</textarea>
</div>

Now CSS code will be like:

.form textarea {
    height: 220px;
    width: 342px;
}

Problem solved.

The DragListView lib does this really neat with very nice support for custom animations such as elevation animations. It is also still maintained and updated on a regular basis.

Here is how you use it:

1: Add the lib to gradle first

dependencies {
    compile 'com.github.woxthebox:draglistview:1.2.1'
}

2: Add list from xml

<com.woxthebox.draglistview.DragListView
    android:id="@+id/draglistview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

3: Set the drag listener

mDragListView.setDragListListener(new DragListView.DragListListener() {
    @Override
    public void onItemDragStarted(int position) {
    }

    @Override
    public void onItemDragEnded(int fromPosition, int toPosition) {
    }
});

4: Create an adapter overridden from DragItemAdapter

public class ItemAdapter extends DragItemAdapter<Pair<Long, String>, ItemAdapter.ViewHolder>
    public ItemAdapter(ArrayList<Pair<Long, String>> list, int layoutId, int grabHandleId, boolean dragOnLongPress) {
        super(dragOnLongPress);
        mLayoutId = layoutId;
        mGrabHandleId = grabHandleId;
        setHasStableIds(true);
        setItemList(list);
}

5: Implement a viewholder that extends from DragItemAdapter.ViewHolder

public class ViewHolder extends DragItemAdapter.ViewHolder {
    public TextView mText;

    public ViewHolder(final View itemView) {
        super(itemView, mGrabHandleId);
        mText = (TextView) itemView.findViewById(R.id.text);
    }

    @Override
    public void onItemClicked(View view) {
    }

    @Override
    public boolean onItemLongClicked(View view) {
        return true;
    }
}

The get_ddl procedure for a PACKAGE will return both spec AND body, so it will be better to change the query on the all_objects so the package bodies are not returned on the select.

So far I changed the query to this:

SELECT DBMS_METADATA.GET_DDL(REPLACE(object_type, ' ', '_'), object_name, owner)
FROM all_OBJECTS
WHERE (OWNER = 'OWNER1')
and object_type not like '%PARTITION'
and object_type not like '%BODY'
order by object_type, object_name;

Although other changes might be needed depending on the object types you are getting...

Organizing your application using class make it easy to you and others who work with you to debug problems and improve the app easily.

You can easily organize your application like this:

class hello(Tk):
    def __init__(self):
        super(hello, self).__init__()
        self.btn = Button(text = "Click me", command=close)
        self.btn.pack()
    def close():
        self.destroy()

app = hello()
app.mainloop()

Have you checked this http://docs.python.org/2/install/ ?

1. First you have to install the module

   $ pip install requests

2. Then, before using it you must import it from your program.

   from requests import requests

   Note that your modules must be in the same directory.

3. Then you can use it.

   For this part you have to check for the documentation.

The reason is that for deleting an object, Hibernate requires that the object is in persistent state. Thus, Hibernate first fetches the object (SELECT) and then removes it (DELETE).

Why Hibernate needs to fetch the object first? The reason is that Hibernate interceptors might be enabled (http://docs.jboss.org/hibernate/orm/3.3/reference/en/html/events.html), and the object must be passed through these interceptors to complete its lifecycle. If rows are delete directly in the database, the interceptor won't run.

On the other hand, it's possible to delete entities in one single SQL DELETE statement using bulk operations:

Query q = session.createQuery("delete Entity where id = X");
q.executeUpdate();

Hibernate has a built-in "yes_no" type that would do what you want. It maps to a CHAR(1) column in the database.

Basic mapping: <property name="some_flag" type="yes_no"/>

Annotation mapping (Hibernate extensions):

@Type(type="yes_no")
public boolean getFlag();

While constructs are terminated not with an End While but with a Wend.

While counter < 20
    counter = counter + 1
Wend

Note that this information is readily available in the documentation; just press F1. The page you link to deals with Visual Basic .NET, not VBA. While (no pun intended) there is some degree of overlap in syntax between VBA and VB.NET, one can't just assume that the documentation for the one can be applied directly to the other.

How about writing a filter like below,

$('[myc="blue"]').filter(function () {
   return (this.id == '1' || this.id == '3');
});

Edit: @Jack Thanks.. totally missed it..

$('[myc="blue"]').filter(function() {
   var myId = $(this).attr('myid');   
   return (myId == '1' || myId == '3');
});

        if((deltax > (rectHalfWidth+rectHalfWidth2)*0.9) && (deltay > (rectHalfHeight+rectHalfHeight2)*0.9)){
            //System.out.println("squares relate to angles");
            result=true;
        }
    }while(false);

    return result;
  } 
}

Css below should do the trick.

After the second line the, text will contain ...

line-height: 1em;
max-height: 2em;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: 2;

I guess no one mentioned this so I will write it here. In phpMyAdmin 4.x, there is "Add Routine" link under "Routines" tab at the top row. This link opens a popup dialog where you can write your Stored procedure without worrying about delimiter or template.

Add Routine

Note that for simple test stored procedure, you may want to drop the default parameter which is already given or you can simply set it with a value.

You may see this error when you have added a new file to your code and you're now trying to commit the code without staging(adding) it.

To overcome this, you may first add the file by using git add (git add your_file_name.py) and then committing the changes (git commit -m "Rename Files" -m "Sample script to rename files as you like")

Yield: It is a hint (not guaranteed) to the scheduler that you have done enough and that some other thread of same priority might run and use the CPU.

Thread.sleep();

Sleep: It blocks the execution of that particular thread for a given time.

TimeUnit.MILLISECONDS.sleep(1000);

I resolved this issue for myself. Though, the internal and SD memory was showing a lot of free space. It was an issue with phone memory, which was almost full.

Hence, I moved many of my apps from the phone memory to internal iemory, to free up the phone memory: Settings -> Storage -> Apps (under the internal storage section) -> Internal tab

Here are the ones which are not checked and that are occupying the space on the phone memory.

Click on the Apps (one by one) Click on the button: 'Move to Internal Storage'.

Once you free up a considerable amount of space on the phone memory this way, the error should not come.

Note : In order to set multiple environment variable, script should goes like this

  "scripts": {
    "start": "set NODE_ENV=production&& set MONGO_USER=your_DB_USER_NAME&& set MONGO_PASSWORD=DB_PASSWORD&& set MONGO_DEFAULT_DATABASE=DB_NAME&& node app.js",
  },

You need to pass it as an XML parameter.

Edit: quick code from my project to give you an idea:

CREATE PROCEDURE [dbo].[GetArrivalsReport]
    @DateTimeFrom AS DATETIME,
    @DateTimeTo AS DATETIME,
    @HostIds AS XML(xsdArrayOfULong)
AS
BEGIN
    DECLARE @hosts TABLE (HostId BIGINT)

    INSERT INTO @hosts
        SELECT arrayOfUlong.HostId.value('.','bigint') data
        FROM @HostIds.nodes('/arrayOfUlong/u') as arrayOfUlong(HostId)

Then you can use the temp table to join with your tables. We defined arrayOfUlong as a built in XML schema to maintain data integrity, but you don't have to do that. I'd recommend using it so here's a quick code for to make sure you always get an XML with longs.

IF NOT EXISTS (SELECT * FROM sys.xml_schema_collections WHERE name = 'xsdArrayOfULong')
BEGIN
    CREATE XML SCHEMA COLLECTION [dbo].[xsdArrayOfULong]
    AS N'<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="arrayOfUlong">
        <xs:complexType>
            <xs:sequence>
                <xs:element maxOccurs="unbounded"
                            name="u"
                            type="xs:unsignedLong" />
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>';
END
GO

Its actually enough to add -m to startup parameters on Sql Server Configuration Manager, restart service, go to ssms an add checkbox sysadmin on your account, then remove -m restart again and use as usual.

Database Engine Service Startup Options

-m Starts an instance of SQL Server in single-user mode.

As Opera is powered by Blink since Version 15.0 -webkit-font-smoothing: antialiased does also work on Opera.

Firefox has finally added a property to enable grayscaled antialiasing. After a long discussion it will be available in Version 25 with another syntax, which points out that this property only works on OS X.

-moz-osx-font-smoothing: grayscale;

This should fix blurry icon fonts or light text on dark backgrounds.

.font-smoothing {
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

You may read my post about font rendering on OSX which includes a Sass mixin to handle both properties.
