It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

May be this is alltime multiple connection open issue, you are somewhere in your code opening connections and not closing them properly. use

 using (SqlConnection con = new SqlConnection(connectionString))
        {
            con.Open();
         }

Refer this article: http://msdn.microsoft.com/en-us/library/ms254507(v=vs.80).aspx, The Using block in Visual Basic or C# automatically disposes of the connection when the code exits the block, even in the case of an unhandled exception.

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

All XAMPP packages come with Multibyte String (php_mbstring.dll) extension installed.

If you have accidentally removed DLL file from php/ext folder, just add it back (get the copy from XAMPP zip archive - its downloadable).

If you have deleted the accompanying INI configuration line from php.ini file, add it back as well:

extension=php_mbstring.dll

Also, ensure to restart your webserver (Apache) using XAMPP control panel.

Additional Info on Enabling PHP Extensions

• install extension (e.g. put php_mbstring.dll into /XAMPP/php/ext directory)
• in php.ini, ensure extension directory specified (e.g. extension_dir = "ext")
• ensure correct build of DLL file (e.g. 32bit thread-safe VC9 only works with DLL files built using exact same tools and configuration: 32bit thread-safe VC9)
• ensure PHP API versions match (If not, once you restart the webserver you will receive related error.)

For me, none of the solutions above worked when working with Selenium Web Driver C# + Chrome:

• window.resizeTo(1024, 768); - I want to use the whole screen
• --start-maximized - it is ignored
• driver.manage().window().maximize(); - does not work because it requires some extension and I am not allowed to use Chrome extensions

I managed to get it working using InputSimulator:

var inputSim = new InputSimulator();
// WinKey + UP = Maximize focused window
inputSim.Keyboard.ModifiedKeyStroke(VirtualKeyCode.LWIN, VirtualKeyCode.UP);

REST stands for REpresentational State Transfer and goes a little something like this:

We have a bunch of uniquely addressable 'entities' that we want made available via a web application. Those entities each have some identifier and can be accessed in various formats. REST defines a bunch of stuff about what GET, POST, etc mean for these purposes.

the basic idea with REST is that you can attach a bunch of 'renderers' to different entities so that they can be available in different formats easily using the same HTTP verbs and url formats.

For more clarification on what RESTful means and how it is used google rails. Rails is a RESTful framework so there's loads of good information available in its docs and associated blog posts. Worth a read even if you arent keen to use the framework. For example: http://www.sitepoint.com/restful-rails-part-i/

RESTless means not restful. If you have a web app that does not adhere to RESTful principles then it is not RESTful

dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
        dicts[i] = values[i]
print(dicts)

alternatively

In [7]: dict(list(enumerate(values)))
Out[7]: {0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

This is one ugly way to do this. I would just use a local variable.

EDIT: If size() > 0 as well.

if (orderBean.getFiles().size() + Integer.MIN_VALUE-1 < Integer.MIN_VALUE + 5-1)

Node's crypto module API is still unstable.

As of version 4.0.0, the native Crypto module is not unstable anymore. From the official documentation:

Crypto

Stability: 2 - Stable

The API has proven satisfactory. Compatibility with the npm ecosystem is a high priority, and will not be broken unless absolutely necessary.

So, it should be considered safe to use the native implementation, without external dependencies.

For reference, the modules mentioned bellow were suggested as alternative solutions when the Crypto module was still unstable.

You could also use one of the modules sha1 or md5 which both do the job.

$ npm install sha1

and then

var sha1 = require('sha1');

var hash = sha1("my message");

console.log(hash); // 104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb

or

$ npm install md5

and then

var md5 = require('md5');

var hash = md5("my message");

console.log(hash); // 8ba6c19dc1def5702ff5acbf2aeea5aa

(MD5 is insecure but often used by services like Gravatar.)

The API of these modules won't change!

In my case, simply giving the user permissions on the database fixed it.

So Right click on the database -> Click Properties -> [left hand menu] Click Permissions -> and scroll down to Backup database -> Tick "Grant"

All the answers here didn't work (completely) for me. Just to recap what we wanna do for a complete answer: We have a ScrollView, supposedly filling the device's viewport, thus we set fillViewport to "true" in the layout xml. Then, inside the ScrollView, we have a LinearLayout containing everything else, and that LinearLayout should be at least as high as its parent ScrollView, so stuff that's supposed to be on the bottom (of the LinearLayout) is actually, as we want it, at the bottom of the screen (or at the bottom of the ScrollView, in case the LinearLayout's content has more hight than the screen.

Example activity_main.xml layout:

<ScrollView
    android:id="@+id/layout_scrollwrapper"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fillViewport="true"
    android:layout_alignParentTop="true"
    android:layout_above="@+id/layout_footer"
    >
<LinearLayout
    android:id="@+id/layout_scrollwrapper_inner"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    >
...content which might or might not be higher than screen height...
</LinearLayout>
</ScrollView>

Then, in the activity's onCreate, we "wait" for the LinearLayout's layouting to be done (implying it's parent's layouting is also already done) and then set it's minimum height to the ScrollView's height. Thus it also works in case the ScrollView does not occupy the whole screen height. Whether you call .post(...) on the ScrollView or the inner LinearLayout should not make that much of a difference, if one doesn't work for you, try the other.

public class MainActivity extends AppCompatActivity {

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

    LinearLayout linearLayoutWrapper = findViewById(R.id.layout_scrollwrapper_inner);

    ...

    linearLayoutWrapper.post(() -> {
        linearLayoutWrapper.setMinimumHeight(((ScrollView)linearLayoutWrapper.getParent()).getHeight());
    });
}
...
}

Sadly, it's not an xml-only solution, but it works well enough for me, hope it also helps some other tortured android dev scouring the interwebs in search for a solution to this problem ;D

In most database systems, IN (val1, val2, …) and a series of OR are optimized to the same plan.

The third way would be importing the list of values into a temporary table and join it which is more efficient in most systems, if there are lots of values.

You may want to read this articles:

• Passing parameters in MySQL: IN list vs. temporary table

In your php.ini file check for display_errors. If it is off, then make it on as below:

display_errors = On

It should display warnings/notices/errors .

Please read this

http://www.php.net/manual/en/errorfunc.configuration.php#ini.error-reporting

Add AddType application/x-httpd-php .php to your httpd.conf file if you are using Apache 2.4

You can even use FileOutputStream to get what you need. This is how it can be done,

File file = new File(Environment.getExternalStorageDirectory(), "abc.txt");
FileOutputStream fOut = new FileOutputStream(file, true);
OutputStreamWriter osw = new OutputStreamWriter(fOut);
osw.write("whatever you need to write");
osw.flush();
osw.close();

Remember Ternary operator and Elvis operator hold separate meanings in Kotlin unlike in many popular languages. Doing expression? value1: value2 would give you bad words by the Kotlin compiler, unlike any other language as there is no ternary operator in Kotlin as mentioned in the official docs. The reason is that the if, when and try-catch statements themselves return values.

So, doing expression? value1: value2 can be replaced by

val max = if (a > b) print("Choose a") else print("Choose b")

The Elvis operator that Kotlin has, works only in the case of nullable variables ex.:

If I do something like value3 = value1 ?: value2 then if value1 is null then value2 would be returned otherwise value1 would be returned.

A more clear understanding can be achieved from these answers.

to pass the event object:

<p id="p" onclick="doSomething(event)">

to get the clicked child element (should be used with event parameter:

function doSomething(e) {
    e = e || window.event;
    var target = e.target || e.srcElement;
    console.log(target);
}

to pass the element itself (DOMElement):

<p id="p" onclick="doThing(this)">

see live example on jsFiddle.

You can specify the name of the event as above, but alternatively your handler can access the event parameter as described here: "When the event handler is specified as an HTML attribute, the specified code is wrapped into a function with the following parameters". There's much more additional documentation at the link.

You must specify the full path of the resource file as the name of 'image within the resources of your application, see example below.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    PictureBox1.Image = My.Resources.Chrysanthemum
End Sub

In the path assigned to the Image property after MyResources specify the name of the resource.

But before you do whatever you have to import in the resource section of your application from an image file exists or it can create your own.

Bye

Any time you need a reference to the current object.

One particularly handy scenario is when your object is calling a function and wants to pass itself into it.

Example:

void onChange()
{
    screen.draw(this);
}

jQuery('#id').css("display","block")

The display property can have many possible values, among which are block, inline, inline-block, and many more.

The .show() method doesn't set it necessarily to block, but rather resets it to what you defined it (if at all).

In the jQuery source code, you can see how they're setting the display property to "" (an empty string) to check what it was before any jQuery manipulation: little link.

On the other hand, hiding is done via display: none;, so you can consider .hide() and .css("display", "none") equivalent to some point.

It's recommended to use .show() and .hide() anyway to avoid any gotcha's (plus, they're shorter).

Steve Smith did two great blog posts which demonstrate how to use his CachedRepository pattern in ASP.NET MVC. It uses the repository pattern effectively and allows you to get caching without having to change your existing code.

http://ardalis.com/Introducing-the-CachedRepository-Pattern

http://ardalis.com/building-a-cachedrepository-via-strategy-pattern

In these two posts he shows you how to set up this pattern and also explains why it is useful. By using this pattern you get caching without your existing code seeing any of the caching logic. Essentially you use the cached repository as if it were any other repository.

Thanks All! I am combined feedback and finally manage to convert from text input ( string ) to Integer. Plus it could tell me whether the input is integer :)

NSNumberFormatter * f = [[NSNumberFormatter alloc] init];
[f setNumberStyle:NSNumberFormatterDecimalStyle];
NSNumber * myNumber = [f numberFromString:thresholdInput.text];

int minThreshold = [myNumber intValue]; 

NSLog(@"Setting for minThreshold %i", minThreshold);

if ((int)minThreshold < 1 )
{
    NSLog(@"Not a number");
}
else
{
    NSLog(@"Setting for integer minThreshold %i", minThreshold);
}
[f release];

This is one way to access(and have used) self from inside a decorator defined inside the same class:

class Thing(object):
    def __init__(self, name):
        self.name = name

    def debug_name(function):
        def debug_wrapper(*args):
            self = args[0]
            print 'self.name = ' + self.name
            print 'running function {}()'.format(function.__name__)
            function(*args)
            print 'self.name = ' + self.name
        return debug_wrapper

    @debug_name
    def set_name(self, new_name):
        self.name = new_name

Output (tested on Python 2.7.10):

>>> a = Thing('A')
>>> a.name
'A'
>>> a.set_name('B')
self.name = A
running function set_name()
self.name = B
>>> a.name
'B'

The example above is silly, but it works.

I want to add that you can use the .WRITE clause for partial or full updates and high performance appends to varchar(max)/nvarchar(max) data types.

Here you can found full example of using .WRITE clause.

The expression $(document).ready(function() deprecated in jQuery3.

Take into account I didn't include the showless button.

Here's the code:

JS

$(function () {
    x=3;
    $('#myList li').slice(0, 3).show();
    $('#loadMore').on('click', function (e) {
        e.preventDefault();
        x = x+5;
        $('#myList li').slice(0, x).slideDown();
    });
});

CSS

#myList li{display:none;
}
#loadMore {
    color:green;
    cursor:pointer;
}
#loadMore:hover {
    color:black;
}

I've been using parts of the marketcetera platform. They support all kinds of marketdata sources and brokers and you should easily be able to add more brokers and/or data providers. This is not a direct broker API of course, but that helps you avoid vendor lock-in so that might be a good thing. And of course all the tools they use are open source.

Here's a jsfiddle I found on another thread, works with esc key also: http://jsfiddle.net/S5ftb/404

    var button = $('#open')[0]
    var el     = $('#test')[0]

    $(button).on('click', function(e) {
      $(el).show()
      e.stopPropagation()
    })

    $(document).on('click', function(e) {
      if ($(e.target).closest(el).length === 0) {
        $(el).hide()
      }
    })

    $(document).on('keydown', function(e) {
      if (e.keyCode === 27) {
        $(el).hide()
      }
    })

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

In short:

• OpenJDK has multiple meanings and can refer to:
  • free and open source implementation of the Java Platform, Standard Edition (Java SE)
  • open source repository — the Java source code aka OpenJDK project
  • prebuilt OpenJDK binaries maintained by Oracle
  • prebuilt OpenJDK binaries maintained by the OpenJDK community
• AdoptOpenJDK — prebuilt OpenJDK binaries maintained by community (open source licensed)

Explanation:

Prebuilt OpenJDK (or distribution) — binaries, built from http://hg.openjdk.java.net/, provided as an archive or installer, offered for various platforms, with a possible support contract.

OpenJDK, the source repository (also called OpenJDK project) - is a Mercurial-based open source repository, hosted at http://hg.openjdk.java.net. The Java source code. The vast majority of Java features (from the VM and the core libraries to the compiler) are based solely on this source repository. Oracle have an alternate fork of this.

OpenJDK, the distribution (see the list of providers below) - is free as in beer and kind of free as in speech, but, you do not get to call Oracle if you have problems with it. There is no support contract. Furthermore, Oracle will only release updates to any OpenJDK (the distribution) version if that release is the most recent Java release, including LTS (long-term support) releases. The day Oracle releases OpenJDK (the distribution) version 12.0, even if there's a security issue with OpenJDK (the distribution) version 11.0, Oracle will not release an update for 11.0. Maintained solely by Oracle.

Some OpenJDK projects - such as OpenJDK 8 and OpenJDK 11 - are maintained by the OpenJDK community and provide releases for some OpenJDK versions for some platforms. The community members have taken responsibility for releasing fixes for security vulnerabilities in these OpenJDK versions.

AdoptOpenJDK, the distribution is very similar to Oracle's OpenJDK distribution (in that it is free, and it is a build produced by compiling the sources from the OpenJDK source repository). AdoptOpenJDK as an entity will not be backporting patches, i.e. there won't be an AdoptOpenJDK 'fork/version' that is materially different from upstream (except for some build script patches for things like Win32 support). Meaning, if members of the community (Oracle or others, but not AdoptOpenJDK as an entity) backport security fixes to updates of OpenJDK LTS versions, then AdoptOpenJDK will provide builds for those. Maintained by OpenJDK community.

OracleJDK - is yet another distribution. Starting with JDK12 there will be no free version of OracleJDK. Oracle's JDK distribution offering is intended for commercial support. You pay for this, but then you get to rely on Oracle for support. Unlike Oracle's OpenJDK offering, OracleJDK comes with longer support for LTS versions. As a developer you can get a free license for personal/development use only of this particular JDK, but that's mostly a red herring, as 'just the binary' is basically the same as the OpenJDK binary. I guess it means you can download security-patched versions of LTS JDKs from Oracle's websites as long as you promise not to use them commercially.

Note. It may be best to call the OpenJDK builds by Oracle the "Oracle OpenJDK builds".

Donald Smith, Java product manager at Oracle writes:

Ideally, we would simply refer to all Oracle JDK builds as the "Oracle JDK", either under the GPL or the commercial license, depending on your situation. However, for historical reasons, while the small remaining differences exist, we will refer to them separately as Oracle’s OpenJDK builds and the Oracle JDK.

_{Free Builds from Source - the distribution source code is publicly available and one can assemble its own build}

_{Free Binary Distributions - the distribution binaries are publicly available for download and usage}

_{Extended Updates - aka LTS (long-term support) - Public Updates beyond the 6-month release lifecycle}

_{Commercial Support - some providers offer extended updates and customer support to paying customers, e.g. Oracle JDK (support details)}

_{Permissive License - the distribution license is non-protective, e.g. Apache 2.0}

Which Java Distribution Should I Use?

In the Sun/Oracle days, it was usually Sun/Oracle producing the proprietary downstream JDK distributions based on OpenJDK sources. Recently, Oracle had decided to do their own proprietary builds only with the commercial support attached. They graciously publish the OpenJDK builds as well on their https://jdk.java.net/ site.

What is happening starting JDK 11 is the shift from single-vendor (Oracle) mindset to the mindset where you select a provider that gives you a distribution for the product, under the conditions you like: platforms they build for, frequency and promptness of releases, how support is structured, etc. If you don't trust any of existing vendors, you can even build OpenJDK yourself.

Each build of OpenJDK is usually made from the same original upstream source repository (OpenJDK “the project”). However each build is quite unique - $free or commercial, branded or unbranded, pure or bundled (e.g., BellSoft Liberica JDK offers bundled JavaFX, which was removed from Oracle builds starting JDK 11).

If no environment (e.g., Linux) and/or license requirement defines specific distribution and if you want the most standard JDK build, then probably the best option is to use OpenJDK by Oracle or AdoptOpenJDK.

Aleksey Shipilev about JDK updates interview by Opsian (published on June 27, 2019)

When you don't care about removing the Html Dom-Element, use *ngIf.

Otherwise, use this:

<div [style.visibility]="(numberOfUnreadAlerts == 0) ? 'hidden' : 'visible' ">
   COUNTER: {{numberOfUnreadAlerts}} 
</div>

This worked for me and also localised it:

$.datepicker.setDefaults( $.datepicker.regional[ "fr" ] );
$(function() {
   $( "#txtDespatchDate" ).datepicker( );
   $( "#txtDespatchDate" ).datepicker( "option", "dateFormat", "dd/mm/yy" );
   $('#txtDespatchDate').datepicker('setDate', new Date());
});

I got here just by accident and the OP's question got my attention. Unfortunately I do not understand any of the explanations from the top. Seems to me like everybody knows it, gets it, accetps it, just cannot explain.

Luckily, a pure sentence from PHP documentation on foreach makes this completely clear:

Warning: Reference of a $value and the last array element remain even after the foreach loop. It is recommended to destroy it by unset().

Use procmon to define your problem.

You can use text property in your xml file for particular Edittext fields. For example :

<EditText
    android:id="@+id/ET_User"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="yourusername"/>

like this all Edittext fields contains text whatever u want,if user wants to change particular Edittext field he remove older text and enter his new text.

In Another way just you get the particular Edittext field id in activity class and set text to that one.

Another way = programmatically

Example:

EditText username=(EditText)findViewById(R.id.ET_User);

username.setText("jack");

Use the following functions:

   /**
     * Returns the number of days between two dates. The time part of the
     * days is ignored in this calculation, so 2007-01-01 13:00 and 2007-01-02 05:00
     * have one day inbetween.
     */
    public static long daysBetween(Date firstDate, Date secondDate) {
        // We only use the date part of the given dates
        long firstSeconds = truncateToDate(firstDate).getTime()/1000;
        long secondSeconds = truncateToDate(secondDate).getTime()/1000;
        // Just taking the difference of the millis.
        // These will not be exactly multiples of 24*60*60, since there
        // might be daylight saving time somewhere inbetween. However, we can

The minimal setup for an HTTPS server in Node.js would be something like this :

var https = require('https');
var fs = require('fs');

var httpsOptions = {
    key: fs.readFileSync('path/to/server-key.pem'),
    cert: fs.readFileSync('path/to/server-crt.pem')
};

var app = function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}

https.createServer(httpsOptions, app).listen(4433);

If you also want to support http requests, you need to make just this small modification :

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

var httpsOptions = {
    key: fs.readFileSync('path/to/server-key.pem'),
    cert: fs.readFileSync('path/to/server-crt.pem')
};

var app = function (req, res) {
  res.writeHead(200);
  res.end("hello world\n");
}

http.createServer(app).listen(8888);
https.createServer(httpsOptions, app).listen(4433);

First of all, you are trying to access non-static member var outside the class which is not allowed in C++.

Mark's answer is correct.

Anything that is part of Outer should have access to all of Outer's members, public or private.

So you can do two things, either declare var as static or use a reference of an instance of the outer class to access 'var' (because a friend class or function also needs reference to access private data).

Static var

Change var to static If you don't want var to be associated with the instances of the class.

#include <iostream>

class Outer {

private:
    static const char* const MYCONST;
    static int var;

public:
   class Inner {
    public:
        Inner() {
          Outer::var = 1;
        }
        void func() ;
    };
};

int Outer::var = 0;

void Outer::Inner::func() {
    std::cout << "var: "<< Outer::var;
}

int main() {
  Outer outer;
  Outer::Inner inner;
  inner.func();

}

Output- var: 1

Non-static var

An object's reference is must access any non-static member variables.

#include <iostream>

class Outer {

private:
    static const char* const MYCONST;
    int var;

public:
   class Inner {
    public:
        Inner(Outer &outer) {
          outer.var = 1;
        }
        void func(const Outer &outer) ;
    };
};

void Outer::Inner::func(const Outer &outer) {
    std::cout << "var: "<< outer.var;
}

int main() {
  Outer outer;
  Outer::Inner inner(outer);
  inner.func(outer);

}

Output- var: 1

Vertical align only works in some select cases. The easiest way to make it function is to set display: table in the parent element's CSS and display: table-cell; to the child element and then apply your vertical align attribute.

This puts the functionality into a method named function, allowing for your code to encapsulate it or for the method to be made a jquery extension. Just used on my code, works perfectly

var nOffsetTop  = /* whatever value, set from wherever */;
var nOffsetLeft = /* whatever value, set from wherever */;

$(input).datepicker
(
   beforeShow : function(oInput, oInst) 
   { 
      AlterPostion(oInput, oInst, nOffsetTop, nOffsetLeft); 
   }
);

/* can be converted to extension, or whatever*/
var AlterPosition = function(oInput, oItst, nOffsetTop, nOffsetLeft)
{
   var divContainer = oInst.dpDiv;
   var oElem        = $(this);
       oInput       = $(oInput);

   setTimeout(function() 
   { 
      divContainer.css
      ({ 
         top  : (nOffsetTop >= 0 ? "+=" + nOffsetTop : "-=" + (nOffsetTop * -1)), 
         left : (nOffsetTop >= 0 ? "+=" + nOffsetLeft : "-=" + (nOffsetLeft * -1))
      }); 
   }, 10);
}

The shortcuts I use in Visual Studio for multiline (aka box) select are Shift + Alt + up/down/left/right

To create this in Visual Studio Code you can add these keybindings to the keybindings.json file (menu File → Preferences → Keyboard shortcuts).

{ "key": "shift+alt+down", "command": "editor.action.insertCursorBelow",
                                 "when": "editorTextFocus" },
{ "key": "shift+alt+up", "command": "editor.action.insertCursorAbove",
                                 "when": "editorTextFocus" },
{ "key": "shift+alt+right", "command": "cursorRightSelect",
                                     "when": "editorTextFocus" },
{ "key": "shift+alt+left", "command": "cursorLeftSelect",
                                     "when": "editorTextFocus" }

A key point that I find missing in the above answers is that urllib returns an object of type <class http.client.HTTPResponse> whereas requests returns <class 'requests.models.Response'>.

Due to this, read() method can be used with urllib but not with requests.

P.S. : requests is already rich with so many methods that it hardly needs one more as read() ;>

in addition to @emil-vikström's answer, checking for variable!=null would be true for variable!==null as well as for variable!==undefined (or typeof(variable)!="undefined").

As others have explained that it is not possible, but here's alternative solution, it requires a little tuning, but it works like datetime column.

I started to think, how I could make formatting possible. I got an idea. What about making trigger for it? I mean, adding column with type char, and then updating that column using a MySQL trigger. And that worked! I made some research related to triggers, and finally come up with these queries:

CREATE TRIGGER timestampper BEFORE INSERT ON table
FOR EACH
ROW SET NEW.timestamp = DATE_FORMAT(NOW(), '%d-%m-%Y %H:%i:%s');

CREATE TRIGGER timestampper BEFORE UPDATE ON table
FOR EACH
ROW SET NEW.timestamp = DATE_FORMAT(NOW(), '%d-%m-%Y %H:%i:%s');

You can't use TIMESTAMP or DATETIME as a column type, because these have their own format, and they update automatically.

So, here's your alternative timestamp or datetime alternative! Hope this helped, at least I'm glad that I got this working.

public bool doesWebElementExist(string linkexist)
{
     try
     {
        driver.FindElement(By.XPath(linkexist));
        return true;
     }
     catch (NoSuchElementException e)
     {
        return false;
     }
}

Just document it here on Windows you need to escape the \ character:

"e:\\directory\\-"

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

It's a black and white decision to me. If the image is part of the content such as a logo or diagram or person (real person, not stock photo people) then use the <img /> tag plus alt attribute. For everything else there's CSS background images.

The other time to use CSS background images is when doing image-replacement of text eg. paragraphs/headers.

I tried many but this worked fine for me.

npm config rm proxy
npm config rm https-proxy

above 2 commands is enough if it doesn't work try this as well.

npm config --global rm proxy
npm config --global rm https-proxy

You can't. Javascript runs client side, C# runs server side.

In fact, your server will run all the C# code, generating Javascript. The Javascript then, is run in the browser. As said in the comments, the compiler doesn't know Javascript.

To call the functionality on your server, you'll have to use techniques such as AJAX, as said in the other answers.

What have you tried, what was the problem?

Creating DataColumns and add values to a DataTable is straight forward:

Dim dt = New DataTable()
Dim dcID = New DataColumn("ID", GetType(Int32))
Dim dcName = New DataColumn("Name", GetType(String))
dt.Columns.Add(dcID)
dt.Columns.Add(dcName)
For i = 1 To 1000
    dt.Rows.Add(i, "Row #" & i)
Next

Edit:

If you want to read a xml file and load a DataTable from it, you can use DataTable.ReadXml.

Well, you essentially create a JDialog, add your text components and make it visible. It might help if you narrow down which specific bit you're having trouble with.

And a PHP example, multiple matching lines will be displayed:

<?php
$file = 'somefile.txt';
$searchfor = 'name';

// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');

// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
   echo "Found matches:\n";
   echo implode("\n", $matches[0]);
}
else{
   echo "No matches found";
}

The most important difference is this:

• In case of persist method, if the entity that is to be managed in the persistence context, already exists in persistence context, the new one is ignored. (NOTHING happened)

• But in case of merge method, the entity that is already managed in persistence context will be replaced by the new entity (updated) and a copy of this updated entity will return back. (from now on any changes should be made on this returned entity if you want to reflect your changes in persistence context)

@Carlos: In his article Tim Bray recommends this (as does another post by Google), but unfortunately it is not being applied by all tablet manufacturers.

... We recommend that manufactures of large-form-factor devices remove "Mobile" from the User Agent...

Most Android tablet user-agent strings I've seen use mobile safari, e.g. the Samsung Galaxy Tab:

Mozilla/5.0 (Linux; U; Android 2.2; en-us; SCH-I800 Build/FROYO) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1

So at the moment I am checking on device names to detect Android tablets. As long as there are just a few models on the market, that's ok but soon this will be an ugly solution.

At least in case of the XOOM, the mobile part seems to be gone:

Mozilla/5.0 (Linux; U; Android 3.0; en-us; Xoom Build/HRI39) AppleWebKit/534.13 (KHTML, like Gecko) Version/4.0 Safari/534.13

But as there are currently only tablets with Andorid 3.x, checking on Android 3 would be enough.

If you want this to be handled by UILabel and not UITextView, you can make UILabel subclass, like this one:

class LinkedLabel: UILabel {

fileprivate let layoutManager = NSLayoutManager()
fileprivate let textContainer = NSTextContainer(size: CGSize.zero)
fileprivate var textStorage: NSTextStorage?


override init(frame aRect:CGRect){
    super.init(frame: aRect)
    self.initialize()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.initialize()
}

func initialize(){

    let tap = UITapGestureRecognizer(target: self, action: #selector(LinkedLabel.handleTapOnLabel))
    self.isUserInteractionEnabled = true
    self.addGestureRecognizer(tap)
}

override var attributedText: NSAttributedString?{
    didSet{
        if let _attributedText = attributedText{
            self.textStorage = NSTextStorage(attributedString: _attributedText)

            self.layoutManager.addTextContainer(self.textContainer)
            self.textStorage?.addLayoutManager(self.layoutManager)

            self.textContainer.lineFragmentPadding = 0.0;
            self.textContainer.lineBreakMode = self.lineBreakMode;
            self.textContainer.maximumNumberOfLines = self.numberOfLines;
        }

    }
}

func handleTapOnLabel(tapGesture:UITapGestureRecognizer){

    let locationOfTouchInLabel = tapGesture.location(in: tapGesture.view)
    let labelSize = tapGesture.view?.bounds.size
    let textBoundingBox = self.layoutManager.usedRect(for: self.textContainer)
    let textContainerOffset = CGPoint(x: ((labelSize?.width)! - textBoundingBox.size.width) * 0.5 - textBoundingBox.origin.x, y: ((labelSize?.height)! - textBoundingBox.size.height) * 0.5 - textBoundingBox.origin.y)

    let locationOfTouchInTextContainer = CGPoint(x: locationOfTouchInLabel.x - textContainerOffset.x, y: locationOfTouchInLabel.y - textContainerOffset.y)
    let indexOfCharacter = self.layoutManager.characterIndex(for: locationOfTouchInTextContainer, in: self.textContainer, fractionOfDistanceBetweenInsertionPoints: nil)


    self.attributedText?.enumerateAttribute(NSLinkAttributeName, in: NSMakeRange(0, (self.attributedText?.length)!), options: NSAttributedString.EnumerationOptions(rawValue: UInt(0)), using:{
        (attrs: Any?, range: NSRange, stop: UnsafeMutablePointer<ObjCBool>) in

        if NSLocationInRange(indexOfCharacter, range){
            if let _attrs = attrs{

                UIApplication.shared.openURL(URL(string: _attrs as! String)!)
            }
        }
    })

}}

This class was made by reusing code from this answer. In order to make attributed strings check out this answer. And here you can find how to make phone urls.

This is how I implemented my strcmp: it works like this: it compares first letter of the two strings, if it is identical, it continues to the next letter. If not, it returns the corresponding value. It is very simple and easy to understand: #include

//function declaration:
int strcmp(char string1[], char string2[]);

int main()
{
    char string1[]=" The San Antonio spurs";
    char string2[]=" will be champins again!";
    //calling the function- strcmp
    printf("\n number returned by the strcmp function: %d", strcmp(string1, string2));
    getch();
    return(0);
}

/**This function calculates the dictionary value of the string and compares it to another string.
it returns a number bigger than 0 if the first string is bigger than the second
it returns a number smaller than 0 if the second string is bigger than the first
input: string1, string2
output: value- can be 1, 0 or -1 according to the case*/
int strcmp(char string1[], char string2[])
{
    int i=0;
    int value=2;    //this initialization value could be any number but the numbers that can be      returned by the function
    while(value==2)
    {
        if (string1[i]>string2[i])
        {
            value=1;
        }
        else if (string1[i]<string2[i])
        {
            value=-1;
        }
        else
        {
            i++;
        }
    }
    return(value);
}

Here I have a solution that avoid multiple requests, for loops and old document removal.

You can easily create a new idea manually using something like:_id:ObjectId() But knowing Mongo will automatically assign an _id if missing, you can use aggregate to create a $project containing all the fields of your document, but omit the field _id. You can then save it with $out

So if your document is:

{
"_id":ObjectId("5b5ed345cfbce6787588e480"),
"title": "foo",
"description": "bar"
}

Then your query will be:

    db.getCollection('myCollection').aggregate([
        {$match:
             {_id: ObjectId("5b5ed345cfbce6787588e480")}
        }        
        {$project:
            {
             title: '$title',
             description: '$description'             
            }     
        },
        {$out: 'myCollection'}
    ])

It doesn't. It makes 0 <= r < 1, but your original is 0 <= r <= 1.

Note that this can lead to undefined behavior if RAND_MAX + 1 overflows.

You can extend multiple Interfaces but you cannot extend multiple classes.

The reason that it is not possible in Java to extending multiple classes, is the bad experience from C++ where this is possible.

The alternative for multipe inheritance is that a class can implement multiple interfaces (or an Interface can extend multiple Interfaces)

View Custmv;

 private void initViews() {
        inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        Custmv = inflater.inflate(R.layout.id_number_edit_text_custom, this, true);
        editText = (EditText) findViewById(R.id.id_number_custom);
        loadButton = (ImageButton) findViewById(R.id.load_data_button);
        loadButton.setVisibility(RelativeLayout.INVISIBLE);
        loadData();
    }

private void loadData(){
        loadButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                EditText firstName = (EditText) Custmv.getParent().findViewById(R.id.display_name);
                firstName.setText("Some Text");
            }
        });
    }

try like this.

You could try using a Polyfill. The following Polyfill was published in 2019 and did the trick for me. It assigns the Promise function to the window object.

used like: window.Promise https://www.npmjs.com/package/promise-polyfill

If you want more information on Polyfills check out the following MDN web doc https://developer.mozilla.org/en-US/docs/Glossary/Polyfill

In iOS 7, UIKit added an initWithData:options:documentAttributes:error: method which can initialize an NSAttributedString using HTML, eg:

[[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUTF8StringEncoding] 
                                 options:@{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                                           NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)} 
                      documentAttributes:nil error:nil];

In Swift:

let htmlData = NSString(string: details).data(using: String.Encoding.unicode.rawValue)
let options = [NSAttributedString.DocumentReadingOptionKey.documentType:
        NSAttributedString.DocumentType.html]
let attributedString = try? NSMutableAttributedString(data: htmlData ?? Data(),
                                                          options: options,
                                                          documentAttributes: nil)

This image explains normal script tag, async and defer

• Async scripts are executed as soon as the script is loaded, so it doesn't guarantee the order of execution (a script you included at the end may execute before the first script file )

• Defer scripts guarantees the order of execution in which they appear in the page.

Ref this link : http://www.growingwiththeweb.com/2014/02/async-vs-defer-attributes.html

I have found a variety of runtimes including Visual Studio(VS) versions are available at http://scn.sap.com/docs/DOC-7824

other way to compile using -Xlint:unchecked through command line

javac abc.java -Xlint:unchecked

it will show the unchecked and unsafe warnings.

If you want an explicit check against false (and not undefined, null and others which I assume as you are using !== instead of !=) then yes, you have to use that.

Also, this is the same in a slightly smaller footprint:

if(borrar() !== !1)

There is a built-in function in bytearray that does what you intend.

bytearray.fromhex("de ad be ef 00")

It returns a bytearray and it reads hex strings with or without space separator.

You can't return arrays from functions in C. You also can't (shouldn't) do this:

char *returnArray(char array []){
 char returned [10];
 //methods to pull values from array, interpret them, and then create new array
 return &(returned[0]); //is this correct?
} 

returned is created with automatic storage duration and references to it will become invalid once it leaves its declaring scope, i.e., when the function returns.

You will need to dynamically allocate the memory inside of the function or fill a preallocated buffer provided by the caller.

Option 1:

dynamically allocate the memory inside of the function (caller responsible for deallocating ret)

char *foo(int count) {
    char *ret = malloc(count);
    if(!ret)
        return NULL;

    for(int i = 0; i < count; ++i) 
        ret[i] = i;

    return ret;
}

Call it like so:

int main() {
    char *p = foo(10);
    if(p) {
        // do stuff with p
        free(p);
    }

    return 0;
}

Option 2:

fill a preallocated buffer provided by the caller (caller allocates buf and passes to the function)

void foo(char *buf, int count) {
    for(int i = 0; i < count; ++i)
        buf[i] = i;
}

And call it like so:

int main() {
    char arr[10] = {0};
    foo(arr, 10);
    // No need to deallocate because we allocated 
    // arr with automatic storage duration.
    // If we had dynamically allocated it
    // (i.e. malloc or some variant) then we 
    // would need to call free(arr)
}

i know i am late for this answer but the correct answer seems to be

See :help getcompletion():

:echo getcompletion('', 'color')

which you can assign to a variable:

:let foo = getcompletion('', 'color')

or use in an expression register:

:put=getcompletion('', 'color')

This is not my answer, this solution is provided by u/romainl in this post on reddit.

Use contains instead:

In [10]: df.b.str.contains('^f')
Out[10]: 
0    False
1     True
2     True
3    False
Name: b, dtype: bool

In my case the problem was how travelsize comment.. The order of imports between bootstrap.js and jquery. Because I'am using the template Metronic and doesn't check before

You can pre-fetch your data by using Resolvers in Angular2+, Resolvers process your data before your Component fully be loaded.

There are many cases that you want to load your component only if there is certain thing happening, for example navigate to Dashboard only if the person already logged in, in this case Resolvers are so handy.

Look at the simple diagram I created for you for one of the way you can use the resolver to send the data to your component.

Applying Resolver to your code is pretty simple, I created the snippets for you to see how the Resolver can be created:

import { Injectable } from '@angular/core';
import { Router, Resolve, RouterStateSnapshot, ActivatedRouteSnapshot } from '@angular/router';
import { MyData, MyService } from './my.service';

@Injectable()
export class MyResolver implements Resolve<MyData> {
  constructor(private ms: MyService, private router: Router) {}

  resolve(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): Promise<MyData> {
    let id = route.params['id'];

    return this.ms.getId(id).then(data => {
      if (data) {
        return data;
      } else {
        this.router.navigate(['/login']);
        return;
      }
    });
  }
}

and in the module:

import { MyResolver } from './my-resolver.service';

@NgModule({
  imports: [
    RouterModule.forChild(myRoutes)
  ],
  exports: [
    RouterModule
  ],
  providers: [
    MyResolver
  ]
})
export class MyModule { }

and you can access it in your Component like this:

/////
 ngOnInit() {
    this.route.data
      .subscribe((data: { mydata: myData }) => {
        this.id = data.mydata.id;
      });

And in the Route something like this (usually in the app.routing.ts file):

////
{path: 'yourpath/:id', component: YourComponent, resolve: { myData: MyResolver}}

The reason the exception is not caught is because the Foo() method has a void return type and so when await is called, it simply returns. As DoFoo() is not awaiting the completion of Foo, the exception handler cannot be used.

This opens up a simpler solution if you can change the method signatures - alter Foo() so that it returns type Task and then DoFoo() can await Foo(), as in this code:

public async Task Foo() {
    var x = await DoSomethingThatThrows();
}

public async void DoFoo() {
    try {
        await Foo();
    } catch (ProtocolException ex) {
        // This will catch exceptions from DoSomethingThatThrows
    }
}

Just as a heads up. I had the same problem and none of the above fixed it for me. Eventually I found out that respond.js doesn't parse CSS referenced via @import. I had the whole bootstrap.min.css imported via @import into my main.css.

So make sure you don't have any CSS that contains your media queries referenced via @import.

A good trick is to use inner box-shadow, and let it do all the fading for you rather than applying it to the image.

Here is an example of reading and writing a list of objects of type SNStock that implements NSCoding - we have an accessor for the entire list, watchlist, and two methods to add and remove objects, that is addStock(stock: SNStock) and removeStock(stock: SNStock).

import Foundation

class DWWatchlistController {

  private let kNSUserDefaultsWatchlistKey: String = "dw_watchlist_key"

  private let userDefaults: NSUserDefaults

  private(set) var watchlist:[SNStock] {

    get {
      if let watchlistData : AnyObject = userDefaults.objectForKey(kNSUserDefaultsWatchlistKey) {
        if let watchlist : AnyObject = NSKeyedUnarchiver.unarchiveObjectWithData(watchlistData as! NSData) {
          return watchlist as! [SNStock]
        }
      }
      return []
    }

    set(watchlist) {
      let watchlistData = NSKeyedArchiver.archivedDataWithRootObject(watchlist)
      userDefaults.setObject(watchlistData, forKey: kNSUserDefaultsWatchlistKey)
      userDefaults.synchronize()
    }
  }

  init() {
    userDefaults = NSUserDefaults.standardUserDefaults()
  }

  func addStock(stock: SNStock) {
    var watchlist = self.watchlist
    watchlist.append(stock)
    self.watchlist = watchlist
  }

  func removeStock(stock: SNStock) {
    var watchlist = self.watchlist
    if let index = find(watchlist, stock) {
      watchlist.removeAtIndex(index)
      self.watchlist = watchlist
    }
  }

}

Remember that your object needs to implement NSCoding or else the encoding won't work. Here is what SNStock looks like:

import Foundation

class SNStock: NSObject, NSCoding
{
  let ticker: NSString
  let name: NSString

  init(ticker: NSString, name: NSString)
  {
    self.ticker = ticker
    self.name = name
  }

  //MARK: NSCoding

  required init(coder aDecoder: NSCoder) {
    self.ticker = aDecoder.decodeObjectForKey("ticker") as! NSString
    self.name = aDecoder.decodeObjectForKey("name") as! NSString
  }

  func encodeWithCoder(aCoder: NSCoder) {
    aCoder.encodeObject(ticker, forKey: "ticker")
    aCoder.encodeObject(name, forKey: "name")
  }

  //MARK: NSObjectProtocol

  override func isEqual(object: AnyObject?) -> Bool {
    if let object = object as? SNStock {
      return self.ticker == object.ticker &&
        self.name == object.name
    } else {
      return false
    }
  }

  override var hash: Int {
    return ticker.hashValue
  }
}

Hope this helps!

Here, in this post you will find the detailed code for establishing socket between devices or between two application in the same mobile.

You have to create two application to test below code.

In both application's manifest file, add below permission

<uses-permission android:name="android.permission.INTERNET" />

Alternatively you can have your class implement the InitializingBean interface to provide a callback function (afterPropertiesSet()) which the ApplicationContext will invoke when the bean is constructed.

Perhaps this should be the select (if I understand the question correctly)

select user.user_fname, user.user_lname, parent.user_fname, parent.user_lname

<html>
<head>
<script type="text/javascript">
var number = 123;
var string = "abcd";

function docWrite(variable) {
    document.write(variable);
}
</script>
</head>

<body>
<h1>the value for number is: <script>docWrite(number)</script></h1>

<h2>the text is: <script>docWrite(string)</script> </h2>

You can shorten document.write but can't avoid <script> tag

In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click on android:theme = "@style/AppTheme" in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

At parent= in styles.xml you can browse all available styles by using auto-complete inside the "". E.g. try parent="Theme." with your cursor right after the . and then pressing Ctrl + Space.

You can also preview themes in the preview window in Android Studio.

Word starts page numbering over for each new section by default.

I do it slightly differently than the post above that goes through the ribbon menus, but in both methods you have to go through the document to each section's beginning.

My method:

• open up the footer (or header if that's where your page number is)
• drag-select the page number
• right-click on it
• hit Format Page Numbers
• click on the Continue from Previous Section radio button under Page numbering

I find this right-click method to be a little faster. Also, usually if I insert the page numbers first before I start making any new sections, this problem doesn't happen in the first place.

I think it has more to do with how Windows is configured as hinted by this response: Java -Xmx Option

Some more testing: I was able to allocate 1300MB on an old Windows XP machine with only 768MB physical RAM (plus virtual memory). On my 2GB RAM machine I can only get 1220MB. On various other corporate machines (with older Windows XP) I was able to get 1400MB. The machine with a 1220MB limit is pretty new (just purchased from Dell), so maybe it has newer (and more bloated) Windows and DLLs (it's running Window XP Pro Version 2002 SP2).

Write a script and make it executable. The script should look like what you'd normally use at the command line:

java YourClass

This assumes you've already compiled your .java files and that the java can find your .class files. If java cannot find your .class files, you may want to look at using the -classpath option or setting your CLASSPATH environment variable.

This error can occur even if the name of the function is valid if some mandatory arguments are missing (i.e you did not provide enough arguments).
I got this in an Rcpp context, where I wrote a C++ function with optionnal arguments, and did not provided those arguments in R. It appeared that optionnal arguments from the C++ were seen as mandatory by R. As a result, R could not find a matching function for the correct name but an incorrect number of arguments.

Rcpp Function : SEXP RcppFunction(arg1, arg2=0) {}
R Calls :
RcppFunction(0) raises the error
RcppFunction(0, 0) does not

Try adding window before location (i.e. window.location).

I had the same issue. When compared the java version mentioned in the pom.xml file is different and the JAVA_HOME env variable was pointing to different version of jdk.

Have the JAVA_HOME and pom.xml updated to the same jdk installation path

In WAMP, right click on WAMP tray icon then change the port from 3308 to 3306 like this:

Seems someone have done it by patching the kernel. I just came across a paper titled "Exploiting Smart-Phone USB Connectivity For Fun And Profit" by Angelos Stavrou, Zhaohui Wang, Computer Science Department George Mason University, Fairfax, VA. (available freely by googling the above title). Here the two researchers are investigating the possibility of a compromised android device controlling the attached PC by having the android device presenting itself as an HID device (keyboard). As a proof of concept, it seems that they have successfully patched a kernel doing exactly what you want. They didn't provide detailed steps but anyway I just quote what they said they've done:

.....we developed a special USB gadget driver in addition to existing USB composite interface on the Android Linux kernel using the USB Gadget API for Linux[4]. The UGAL framework helped us implement a simple USB Human Interface Driver (HID) functionality (i.e. device driver) and the glue code between the various kernel APIs. Using the code provided in: “drivers/usb/gadget/composite.c”, we created our own gadget driver as an additional composite USB interface. This driver simulates a USB keyboard device. We can also simulate a USB mouse device sending pre-programmed input command to the desktop system. Therefore, it is straightforward to pose as a normal USB mouse or keyboard device and send predefined command stealthily to simulate malicious interactive user activities. To verify this functionality, in our controlled experiments, we send keycode sequences to perform non-fatal operations and show how such a manipulated device can cause damages In particular, we simulated a Dell USB keyboard (vendorID=413C, productID=2105) sending ”CTRL+ESC” key combination and ”U” and ”Enter” key sequence to reboot the machine. Notice that this only requires USB connection and can gain the ”current user” privilege on the desktop system. With the additional local or remote exploit sent as payload, the malware can escalate the privilege and gain full access of the desktop system.

Beware of the scale factor of your windows (100% / 125% / 150% / 200%). You can get the real screen size by using the following code:

SystemParameters.FullPrimaryScreenHeight
SystemParameters.FullPrimaryScreenWidth

typedef struct{
     char name[30];
     char surname[30];
     int age;
} data;

defines that data should be a block of memory that fits 60 chars plus 4 for the int (see note)

[----------------------------,------------------------------,----]
 ^ this is name              ^ this is surname              ^ this is age

This allocates the memory on the stack.

data s1;

Assignments just copies numbers, sometimes pointers.

This fails

s1.name = "Paulo";

because the compiler knows that s1.name is the start of a struct 64 bytes long, and "Paulo" is a char[] 6 bytes long (6 because of the trailing \0 in C strings)
Thus, trying to assign a pointer to a string into a string.

To copy "Paulo" into the struct at the point name and "Rossi" into the struct at point surname.

memcpy(s1.name,    "Paulo", 6);
memcpy(s1.surname, "Rossi", 6);
s1.age = 1;

You end up with

[Paulo0----------------------,Rossi0-------------------------,0001]

strcpy does the same thing but it knows about \0 termination so does not need the length hardcoded.

Alternatively you can define a struct which points to char arrays of any length.

typedef struct {
  char *name;
  char *surname;
  int age;
} data;

This will create

[----,----,----]

This will now work because you are filling the struct with pointers.

s1.name = "Paulo";
s1.surname = "Rossi";
s1.age = 1;

Something like this

[---4,--10,---1]

Where 4 and 10 are pointers.

Note: the ints and pointers can be different sizes, the sizes 4 above are 32bit as an example.

NodeJS supports http.request as a standard module: http://nodejs.org/docs/v0.4.11/api/http.html#http.request

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

SELECT * FROM pg_stat_activity WHERE datname = 'dbname' and state = 'active';

Since pg_stat_activity contains connection statistics of all databases having any state, either idle or active, database name and connection state should be included in the query to get the desired output.

As of Ansible 2.0 there seems to be an option called strategy on a playbook. When setting the strategy to free, the playbook plays tasks on each host without waiting to the others. See http://docs.ansible.com/ansible/playbooks_strategies.html.

It looks something like this (taken from the above link):

- hosts: all
  strategy: free
  tasks:
  ...

Please note that I didn't check this and I'm very new to Ansible. I was just curious about doing what you described and happened to come acroess this strategy thing.

EDIT:

It seems like this is not exactly what you're trying to do. Maybe "async tasks" is more appropriate as described here: http://docs.ansible.com/ansible/playbooks_async.html.

This includes specifying async and poll on a task. The following is taken from the 2nd link I mentioned:

- name: simulate long running op, allow to run for 45 sec, fire and forget
  command: /bin/sleep 15
  async: 45
  poll: 0

I guess you can specify longer async times if your task is lengthy. You can probably define your three concurrent task this way.

JDBC is a much lower-level (and older) specification than JPA. In it's bare essentials, JDBC is an API for interacting with a database using pure SQL - sending queries and retrieving results. It has no notion of objects or hierarchies. When using JDBC, it's up to you to translate a result set (essentially a row/column matrix of values from one or more database tables, returned by your SQL query) into Java objects.

Now, to understand and use JDBC it's essential that you have some understanding and working knowledge of SQL. With that also comes a required insight into what a relational database is, how you work with it and concepts such as tables, columns, keys and relationships. Unless you have at least a basic understanding of databases, SQL and data modelling you will not be able to make much use of JDBC since it's really only a thin abstraction on top of these things.

The solution is very simple! Put this line before curl_exec:

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

For me it works.

PSH> $cred = Get-Credential

PSH> $cred | Export-CliXml c:\temp\cred.clixml

PSH> $cred2 = Import-CliXml c:\temp\cred.clixml

That hashes it against your SID and the machine's SID, so the file is useless on any other machine, or in anyone else's hands.

Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

The -> operator makes the code more readable than the * operator in some situations.

Such as: (quoted from the EDK II project)

typedef
EFI_STATUS
(EFIAPI *EFI_BLOCK_READ)(
  IN EFI_BLOCK_IO_PROTOCOL          *This,
  IN UINT32                         MediaId,
  IN EFI_LBA                        Lba,
  IN UINTN                          BufferSize,
  OUT VOID                          *Buffer
  );


struct _EFI_BLOCK_IO_PROTOCOL {
  ///
  /// The revision to which the block IO interface adheres. All future
  /// revisions must be backwards compatible. If a future version is not
  /// back wards compatible, it is not the same GUID.
  ///
  UINT64              Revision;
  ///
  /// Pointer to the EFI_BLOCK_IO_MEDIA data for this device.
  ///
  EFI_BLOCK_IO_MEDIA  *Media;

  EFI_BLOCK_RESET     Reset;
  EFI_BLOCK_READ      ReadBlocks;
  EFI_BLOCK_WRITE     WriteBlocks;
  EFI_BLOCK_FLUSH     FlushBlocks;

};

The _EFI_BLOCK_IO_PROTOCOL struct contains 4 function pointer members.

Suppose you have a variable struct _EFI_BLOCK_IO_PROTOCOL * pStruct, and you want to use the good old * operator to call it's member function pointer. You will end up with code like this:

(*pStruct).ReadBlocks(...arguments...)

But with the -> operator, you can write like this:

pStruct->ReadBlocks(...arguments...).

Which looks better?

Nope.

But lo! If you use std::vector<Car>, like you should be (never ever use new[]), then you can specify exactly how elements should be constructed*.

*Well sort of. You can specify the value of which to make copies of.

Like this:

#include <iostream>
#include <vector>

class Car
{
private:
    Car(); // if you don't use it, you can just declare it to make it private
    int _no;
public:
    Car(int no) :
    _no(no)
    {
        // use an initialization list to initialize members,
        // not the constructor body to assign them
    }

    void printNo()
    {
        // use whitespace, itmakesthingseasiertoread
        std::cout << _no << std::endl;
    }
};

int main()
{
    int userInput = 10;

    // first method: userInput copies of Car(5)
    std::vector<Car> mycars(userInput, Car(5)); 

    // second method:
    std::vector<Car> mycars; // empty
    mycars.reserve(userInput); // optional: reserve the memory upfront

    for (int i = 0; i < userInput; ++i)
        mycars.push_back(Car(i)); // ith element is a copy of this

    // return 0 is implicit on main's with no return statement,
    // useful for snippets and short code samples
} 

With the additional function:

void printCarNumbers(Car *cars, int length)
{
    for(int i = 0; i < length; i++) // whitespace! :)
         std::cout << cars[i].printNo();
}

int main()
{
    // ...

    printCarNumbers(&mycars[0], mycars.size());
} 

Note printCarNumbers really should be designed differently, to accept two iterators denoting a range.

This may be overkill for this simple problem. But for Try-Do methods in connection with Linq, I tend to use anonymous classes for more expressive code. It is similar to the answers from Olivier Jacot-Descombes and BA TabNabber:

List<int> ints = strings
    .Select(idString => new { ParseSuccessful = Int32.TryParse(idString, out var id), Value = id })
    .Where(id => id.ParseSuccessful)
    .Select(id => id.Value)
    .ToList();

Code:

using System.Net.Mail

new SmtpClient("smtp.server.com", 25).send("[email protected]", 
                                           "[email protected]", 
                                           "subject", 
                                           "body");

SMTP servers usually have a limit on the number of connection hat can handle at once, if you try to send hundreds of emails you application may appear unresponsive.

Solutions:

• If you are building a WinForm then use a BackgroundWorker to process the queue.
• If you are using IIS SMTP server or a SMTP server that has an outbox folder then you can use SmtpClient().PickupDirectoryLocation = "c:/smtp/outboxFolder"; This will keep your system responsive.
• If you are not using a local SMTP server than you could build a system service to use Filewatcher to monitor a forlder than will then process any emails you drop in there.

You can use the compact language construct to test for the existence of a null variable. Variables that do not exist will not turn up in the result, while null values will show.

$x = null;
$y = 'y';

$r = compact('x', 'y', 'z');
print_r($r);

// Output:
// Array ( 
//  [x] => 
//  [y] => y 
// ) 

In the case of your example:

if (compact('v')) {
   // True if $v exists, even when null. 
   // False on var $v; without assignment and when $v does not exist.
}

Of course for variables in global scope you can also use array_key_exists().

B.t.w. personally I would avoid situations like the plague where there is a semantic difference between a variable not existing and the variable having a null value. PHP and most other languages just does not think there is.

toBe() versus toEqual(): toEqual() checks equivalence. toBe(), on the other hand, makes sure that they're the exact same object.

I would say use toBe() when comparing values, and toEqual() when comparing objects.

When comparing primitive types, toEqual() and toBe() will yield the same result. When comparing objects, toBe() is a stricter comparison, and if it is not the exact same object in memory this will return false. So unless you want to make sure it's the exact same object in memory, use toEqual() for comparing objects.

Check this link out for more info : http://evanhahn.com/how-do-i-jasmine/

Now when looking at the difference between toBe() and toEqual() when it comes to numbers, there shouldn't be any difference so long as your comparison is correct. 5 will always be equivalent to 5.

A nice place to play around with this to see different outcomes is here

Update

An easy way to look at toBe() and toEqual() is to understand what exactly they do in JavaScript. According to Jasmine API, found here:

toEqual() works for simple literals and variables, and should work for objects

toBe() compares with ===

Essentially what that is saying is toEqual() and toBe() are similar Javascripts === operator except toBe() is also checking to make sure it is the exact same object, in that for the example below objectOne === objectTwo //returns false as well. However, toEqual() will return true in that situation.

Now, you can at least understand why when given:

var objectOne = {
    propertyOne: str,
    propertyTwo: num    
}

var objectTwo = {
    propertyOne: str,
    propertyTwo: num    
}

expect(objectOne).toBe(objectTwo); //returns false

That is because, as stated in this answer to a different, but similar question, the === operator actually means that both operands reference the same object, or in case of value types, have the same value.

The variable @array is the list with duplicate elements

%seen=();
@unique = grep { ! $seen{$_} ++ } @array;

You want:

git rm --cached [file]

If you omit the --cached option, it will also delete it from the working tree. git rm is slightly safer than git reset, because you'll be warned if the staged content doesn't match either the tip of the branch or the file on disk. (If it doesn't, you have to add --force.)

You have two records in your json file, and json.loads() is not able to decode more than one. You need to do it record by record.

See Python json.loads shows ValueError: Extra data

OR you need to reformat your json to contain an array:

{
    "foo" : [
       {"name": "XYZ", "address": "54.7168,94.0215", "country_of_residence": "PQR", "countries": "LMN;PQRST", "date": "28-AUG-2008", "type": null},
       {"name": "OLMS", "address": null, "country_of_residence": null, "countries": "Not identified;No", "date": "23-FEB-2017", "type": null}
    ]
}

would be acceptable again. But there cannot be several top level objects.

Actually I cannot agree to each statement.

"COALESCE expects all arguments to be of same datatype."

This is wrong, see below. Arguments can be different data types, that is also documented: If all occurrences of expr are numeric data type or any nonnumeric data type that can be implicitly converted to a numeric data type, then Oracle Database determines the argument with the highest numeric precedence, implicitly converts the remaining arguments to that data type, and returns that data type.. Actually this is even in contradiction to common expression "COALESCE stops at first occurrence of a non-Null value", otherwise test case No. 4 should not raise an error.

Also according to test case No. 5 COALESCE does an implicit conversion of arguments.

DECLARE

    END;

    DBMS_OUTPUT.PUT_LINE( '5. COALESCE(SYSDATE,SYSTIMESTAMP) -> '|| COALESCE(SYSDATE,SYSTIMESTAMP) );

END;

All the above failed for me. But I noticed shift + ? Tab worked as expected (outdenting the line).

So I looked for the "Indent Line" shortcut (which was assigned to alt + ctrl + cmd + 0 ), assigned it to tab, and now I'm happy again.

I also use tab to accept snippet suggestions, so I've set the "when" of "Indent Line" to editorTextFocus && !editorReadonly && !inSnippetMode && !suggestWidgetVisible.

The simplest way to update is as follows:

1. Go to the start screen for Android Studio. If it automatically opens a project when you open it, close that project (not exit).

2. At the bottom there will be a check for updates link which you can use to update to the latest version.

You can't. The problem is not that your app is impatient and timing out; the problem is that an intermediate proxy is impatient and timing out. "The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI." (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.5.5) It most likely indicates that the origin server is having some sort of issue, so it's not responding quickly to the forwarded request.

Possible solutions, none of which are likely to make you happy:

• Increase timeout value of the proxy (if it's under your control)
• Make your request to a different server (if there's another server with the same data)
• Make your request differently (if possible) such that you are requesting less data at a time
• Try again once the server is not having issues

No.

If the user is sophisticated or determined enough to:

1. Open the Excel VBA editor
2. Use the object browser to see the list of all sheets, including VERYHIDDEN ones
3. Change the property of the sheet to VISIBLE or just HIDDEN

then they are probably sophisticated or determined enough to:

1. Search the internet for "remove Excel 2007 project password"
2. Apply the instructions they find.

So what's on this hidden sheet? Proprietary information like price formulas, or client names, or employee salaries? Putting that info in even an hidden tab probably isn't the greatest idea to begin with.

Let's say you have a Dictionary called fooDictionary

fooDictionary.Values.ToList().IndexOf(someValue);

Values.ToList() converts your dictionary values into a List of someValue objects.

IndexOf(someValue) searches your new List looking for the someValue object in question and returns the Index which would match the index of the Key/Value pair in the dictionary.

This method does not care about the dictionary keys, it simply returns the index of the value that you are looking for.

This does not however account for the issue that there may be several matching "someValue" objects.

Both JB Nizet and Jorge_B's answers are correct.

In its simplest form, creating an executable JAR with Gradle is just a matter of adding the appropriate entries to the manifest. However, it's much more common to have dependencies that need to be included on the classpath, making this approach tricky in practice.

The application plugin provides an alternate approach; instead of creating an executable JAR, it provides:

• a run task to facilitate easily running the application directly from the build
• an installDist task that generates a directory structure including the built JAR, all of the JARs that it depends on, and a startup script that pulls it all together into a program you can run
• distZip and distTar tasks that create archives containing a complete application distribution (startup scripts and JARs)

A third approach is to create a so-called "fat JAR" which is an executable JAR that includes not only your component's code, but also all of its dependencies. There are a few different plugins that use this approach. I've included links to a few that I'm aware of; I'm sure there are more.

• shadow
• one-jar
• spring-boot
• capsule

I'm probably going a million miles in the wrong direct (but i'm only young :P ). but couldn't you add the graphic to a panel and then a mouselistener to the graphic object so that when the user on the graphic your action is preformed.

There's interesting stuff on the performance aspects in this question

However I personally would still recommend string.Format unless performance is critical for readability reasons.

string.Format("{0}: {1}", key, value);

Is more readable than

key + ": " + value

For instance. Also provides a nice separation of concerns. Means you can have

string.Format(GetConfigValue("KeyValueFormat"), key, value);

And then changing your key value format from "{0}: {1}" to "{0} - {1}" becomes a config change rather than a code change.

string.Format also has a bunch of format provision built into it, integers, date formatting, etc.

NSString *str = (NSString *)CFURLCreateStringByAddingPercentEscapes(
                             NULL,
                             (CFStringRef)yourString, 
                             NULL, 
                             CFSTR("/:"), 
                             kCFStringEncodingUTF8);

You will need to release or autorelease str yourself.

To provide another approach similar to the answer by @IvanCollantes. It works by additionally filtering the required checkboxes by name. I also simplified the code a bit and checks for a default checked checkbox.

jQuery(function($) {_x000D_
  var requiredCheckboxes = $(':checkbox[required]');_x000D_
  requiredCheckboxes.on('change', function(e) {_x000D_
    var checkboxGroup = requiredCheckboxes.filter('[name="' + $(this).attr('name') + '"]');_x000D_
    var isChecked = checkboxGroup.is(':checked');_x000D_
    checkboxGroup.prop('required', !isChecked);_x000D_
  });_x000D_
  requiredCheckboxes.trigger('change');_x000D_
});

IoC and DI are super common in mature Python code. You just don't need a framework to implement DI thanks to duck typing.

The best example is how you set up a Django application using settings.py:

# settings.py
CACHES = {
    'default': {
        'BACKEND': 'django_redis.cache.RedisCache',
        'LOCATION': REDIS_URL + '/1',
    },
    'local': {
        'BACKEND': 'django.core.cache.backends.locmem.LocMemCache',
        'LOCATION': 'snowflake',
    }
}

Django Rest Framework utilizes DI heavily:

class FooView(APIView):
    # The "injected" dependencies:
    permission_classes = (IsAuthenticated, )
    throttle_classes = (ScopedRateThrottle, )
    parser_classes = (parsers.FormParser, parsers.JSONParser, parsers.MultiPartParser)
    renderer_classes = (renderers.JSONRenderer,)

    def get(self, request, *args, **kwargs):
        pass

    def post(self, request, *args, **kwargs):
        pass

Let me remind (source):

"Dependency Injection" is a 25-dollar term for a 5-cent concept. [...] Dependency injection means giving an object its instance variables. [...].

using JQuery:

myelement=$("#myelement")
[myelement.offset().left, myelement.offset().top,  myelement.width(), myelement.height()]

First, add a textView in the XML file

<TextView  
    android:id="@+id/rate_id"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/what_U_want_to_display_in_first_time"
    />

then add a button in xml file with id btn_change_textView and write this two line of code in onCreate() method of activity

Button btn= (Button) findViewById(R.id. btn_change_textView);
TextView textView=(TextView)findViewById(R.id.rate_id);

then use clickListener() on button object like this

btn.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
      
        textView.setText("write here what u want to display after button click in string");
    }
});

This new answer uses C++11's <chrono> facility. While there are other answers that show how to use <chrono>, none of them shows how to use <chrono> with the RDTSC facility mentioned in several of the other answers here. So I thought I would show how to use RDTSC with <chrono>. Additionally I'll demonstrate how you can templatize the testing code on the clock so that you can rapidly switch between RDTSC and your system's built-in clock facilities (which will likely be based on clock(), clock_gettime() and/or QueryPerformanceCounter.

Note that the RDTSC instruction is x86-specific. QueryPerformanceCounter is Windows only. And clock_gettime() is POSIX only. Below I introduce two new clocks: std::chrono::high_resolution_clock and std::chrono::system_clock, which, if you can assume C++11, are now cross-platform.

First, here is how you create a C++11-compatible clock out of the Intel rdtsc assembly instruction. I'll call it x::clock:

#include <chrono>

namespace x
{

struct clock
{
    typedef unsigned long long                 rep;
    typedef std::ratio<1, 2'800'000'000>       period; // My machine is 2.8 GHz
    typedef std::chrono::duration<rep, period> duration;
    typedef std::chrono::time_point<clock>     time_point;
    static const bool is_steady =              true;

    static time_point now() noexcept
    {
        unsigned lo, hi;
        asm volatile("rdtsc" : "=a" (lo), "=d" (hi));
        return time_point(duration(static_cast<rep>(hi) << 32 | lo));
    }
};

}  // x

All this clock does is count CPU cycles and store it in an unsigned 64-bit integer. You may need to tweak the assembly language syntax for your compiler. Or your compiler may offer an intrinsic you can use instead (e.g. now() {return __rdtsc();}).

To build a clock you have to give it the representation (storage type). You must also supply the clock period, which must be a compile time constant, even though your machine may change clock speed in different power modes. And from those you can easily define your clock's "native" time duration and time point in terms of these fundamentals.

If all you want to do is output the number of clock ticks, it doesn't really matter what number you give for the clock period. This constant only comes into play if you want to convert the number of clock ticks into some real-time unit such as nanoseconds. And in that case, the more accurate you are able to supply the clock speed, the more accurate will be the conversion to nanoseconds, (milliseconds, whatever).

Below is example code which shows how to use x::clock. Actually I've templated the code on the clock as I'd like to show how you can use many different clocks with the exact same syntax. This particular test is showing what the looping overhead is when running what you want to time under a loop:

#include <iostream>

template <class clock>
void
test_empty_loop()
{
    // Define real time units
    typedef std::chrono::duration<unsigned long long, std::pico> picoseconds;
    // or:
    // typedef std::chrono::nanoseconds nanoseconds;
    // Define double-based unit of clock tick
    typedef std::chrono::duration<double, typename clock::period> Cycle;
    using std::chrono::duration_cast;
    const int N = 100000000;
    // Do it
    auto t0 = clock::now();
    for (int j = 0; j < N; ++j)
        asm volatile("");
    auto t1 = clock::now();
    // Get the clock ticks per iteration
    auto ticks_per_iter = Cycle(t1-t0)/N;
    std::cout << ticks_per_iter.count() << " clock ticks per iteration\n";
    // Convert to real time units
    std::cout << duration_cast<picoseconds>(ticks_per_iter).count()
              << "ps per iteration\n";
}

The first thing this code does is create a "real time" unit to display the results in. I've chosen picoseconds, but you can choose any units you like, either integral or floating point based. As an example there is a pre-made std::chrono::nanoseconds unit I could have used.

As another example I want to print out the average number of clock cycles per iteration as a floating point, so I create another duration, based on double, that has the same units as the clock's tick does (called Cycle in the code).

The loop is timed with calls to clock::now() on either side. If you want to name the type returned from this function it is:

typename clock::time_point t0 = clock::now();

(as clearly shown in the x::clock example, and is also true of the system-supplied clocks).

To get a duration in terms of floating point clock ticks one merely subtracts the two time points, and to get the per iteration value, divide that duration by the number of iterations.

You can get the count in any duration by using the count() member function. This returns the internal representation. Finally I use std::chrono::duration_cast to convert the duration Cycle to the duration picoseconds and print that out.

To use this code is simple:

int main()
{
    std::cout << "\nUsing rdtsc:\n";
    test_empty_loop<x::clock>();

    std::cout << "\nUsing std::chrono::high_resolution_clock:\n";
    test_empty_loop<std::chrono::high_resolution_clock>();

    std::cout << "\nUsing std::chrono::system_clock:\n";
    test_empty_loop<std::chrono::system_clock>();
}

Above I exercise the test using our home-made x::clock, and compare those results with using two of the system-supplied clocks: std::chrono::high_resolution_clock and std::chrono::system_clock. For me this prints out:

Using rdtsc:
1.72632 clock ticks per iteration
616ps per iteration

Using std::chrono::high_resolution_clock:
0.620105 clock ticks per iteration
620ps per iteration

Using std::chrono::system_clock:
0.00062457 clock ticks per iteration
624ps per iteration

This shows that each of these clocks has a different tick period, as the ticks per iteration is vastly different for each clock. However when converted to a known unit of time (e.g. picoseconds), I get approximately the same result for each clock (your mileage may vary).

Note how my code is completely free of "magic conversion constants". Indeed, there are only two magic numbers in the entire example:

1. The clock speed of my machine in order to define x::clock.
2. The number of iterations to test over. If changing this number makes your results vary greatly, then you should probably make the number of iterations higher, or empty your computer of competing processes while testing.

Letting a parent have pointer-events: none will disable the child a-tag like this (requires that the div covers the a and hasn't 0 width/height):

<div class="disabled">
   <a href="/"></a>
</div>

where:

.disabled {
    pointer-events: none;
}

I might've over-engineered my own solution without realizing that Type.valueOf("enum string") actually existed.

I guess it gives more granular control but I'm not sure it's really necessary.

public enum Type {
    DEBIT,
    CREDIT;

    public static Map<String, Type> typeMapping = Maps.newHashMap();
    static {
        typeMapping.put(DEBIT.name(), DEBIT);
        typeMapping.put(CREDIT.name(), CREDIT);
    }

    public static Type getType(String typeName) {
        if (typeMapping.get(typeName) == null) {
            throw new RuntimeException(String.format("There is no Type mapping with name (%s)"));
        }
        return typeMapping.get(typeName);
    }
}

I guess you're exchanging IllegalArgumentException for RuntimeException (or whatever exception you wish to throw) which could potentially clean up code.

                    elem.val(orig);
               });  
            }
       };
   })
  .controller('myCtrl', ['$scope', '$interval', function($scope, $interval) {
    $scope.creditCardNumber = "1234567890123456";
  }]);

From the Terminal of Visual Code Studio on Windows 10, this is what worked for me to create a new file:

type > hello.js
echo > orange.js
ni > peach.js

In Ruby Sinatra

response['Access-Control-Allow-Origin'] = '*' 

for everyone or

response['Access-Control-Allow-Origin'] = 'http://yourdomain.name' 

Define the width as 960px, or whatever you prefer, and you're good to go!

#main {
 margin: 0 auto !important;
 float: none !important;
 text-align: center;
 width: 960px;
}

(I couldn't figure this out until I fixed the width, nothing else worked.)

All three way you can use for newline character :

'\n'

"\n"

"""\n"""

Why Oracle did such a poor way to point to java is beyond me. We solved this problem by creating a new link to the JDK

mklink /d C:\ProgramData\Oracle\Java\javapath "C:\Program Files\Java\jdk1.8.0_40\bin\"

The same would work for a JRE if that is all that is required.

This replaces the old symlinks in C:\ProgramData\Oracle\Java\javapath (if they existed previously)

Old but gold!

On MacOS (Catalina 10.15.7) it was a bit weird: I had to rename my dump.sql into dump.zip and after that, i had to use finder(!) to unzip it. in terminal, unzip dump.zip oder tar xfz dump.sql[or .gz .tar ...] leads to error msgs.

Finally, finder has unziped it totally fine, after that i could import the file without problems.

I have developed pure XML based word files in the past. I used .NET, but the language should not matter since it's truely XML. It was not the easiest thing to do (had a project that required it a couple years ago.) These do only work in Word 2007 or above - but all you need is Microsoft's white paper that describe what each tag does. You can accomplish all you want with the tags the same way as if you were using Word (of course a little more painful initially.)

The TimeSpan constructor allows you to pass in seconds. Simply declare a variable of type TimeSpan amount of seconds. Ex:

TimeSpan span = new TimeSpan(0, 0, 500);
span.ToString();

The core thing you're going to want here is git add -p (-p is a synonym for --patch). This provides an interactive way to check in content, letting you decide whether each hunk should go in, and even letting you manually edit the patch if necessary.

To use it in combination with cherry-pick:

git cherry-pick -n <commit> # get your patch, but don't commit (-n = --no-commit)
git reset                   # unstage the changes from the cherry-picked commit
git add -p                  # make all your choices (add the changes you do want)
git commit                  # make the commit!

(Thanks to Tim Henigan for reminding me that git-cherry-pick has a --no-commit option, and thanks to Felix Rabe for pointing out that you need to reset! If you only want to leave a few things out of the commit, you could use git reset <path>... to unstage just those files.)

You can of course provide specific paths to add -p if necessary. If you're starting with a patch you could replace the cherry-pick with apply.

If you really want a git cherry-pick -p <commit> (that option does not exist), your can use

git checkout -p <commit>

That will diff the current commit against the commit you specify, and allow you to apply hunks from that diff individually. This option may be more useful if the commit you're pulling in has merge conflicts in part of the commit you're not interested in. (Note, however, that checkout differs from cherry-pick: checkout tries to apply <commit>'s contents entirely, cherry-pick applies the diff of the specified commit from it's parent. This means that checkout can apply more than just that commit, which might be more than you want.)

JSONArray successObject=new JSONArray();
JSONObject dataObject=new JSONObject();
successObject.put(dataObject.toString());

This works for me.

You can't do that: you must specify fully resolved type, like Data<MyType>. T is just a variable, and as is meaningless.

But if you mean that T will be known, just not statically, you need to create equivalent of TypeReference dynamically. Other questions referenced may already mention this, but it should look something like:

public Data<T> read(InputStream json, Class<T> contentClass) {
   JavaType type = mapper.getTypeFactory().constructParametricType(Data.class, contentClass);
   return mapper.readValue(json, type);
}

Just searched for the docs, and found this:

Containment Operator: The in operator performs containment test. It returns true if the left operand is contained in the right:

{# returns true #}

{{ 1 in [1, 2, 3] }}

{{ 'cd' in 'abcde' }}

A way to solve this without having to rely on URLs is to add a custom attribute to every partial during $routeProvider configuration, like this:

$routeProvider.
    when('/dashboard', {
        templateUrl: 'partials/dashboard.html',
        controller: widgetsController,
        activetab: 'dashboard'
    }).
    when('/lab', {
        templateUrl: 'partials/lab.html',
        controller: widgetsController,
        activetab: 'lab'
    });

Expose $route in your controller:

function widgetsController($scope, $route) {
    $scope.$route = $route;
}

Set the active class based on the current active tab:

<li ng-class="{active: $route.current.activetab == 'dashboard'}"></li>
<li ng-class="{active: $route.current.activetab == 'lab'}"></li>

// Difference in days, hours, and minutes.

TimeSpan ts = EndDate - StartDate;

// Difference in days.

int differenceInDays = ts.Days; // This is in int
double differenceInDays= ts.TotalDays; // This is in double

// Difference in Hours.
int differenceInHours = ts.Hours; // This is in int
double differenceInHours= ts.TotalHours; // This is in double

// Difference in Minutes.
int differenceInMinutes = ts.Minutes; // This is in int
double differenceInMinutes= ts.TotalMinutes; // This is in double

You can also get the difference in seconds, milliseconds and ticks.

One major problem you have is that you're using browser sniffing for no good reason:

if(navigator.appName == 'Netscape')
    {
      vesdiameter  = document.forms['Volume'].elements['VesDiameter'].value;
      // more stuff snipped
    }
    else
    {
      vesdiameter  = eval(document.all.Volume.VesDiameter.value);
      // more stuff snipped
    }

I'm on Chrome, so navigator.appName won't be Netscape. Does Chrome support document.all? Maybe, but then again maybe not. And what about other browsers?

The version of the code on the Netscape branch should work on any browser right the way back to Netscape Navigator 2 from 1996, so you should probably just stick with that... except that it won't work (or isn't guaranteed to work) because you haven't specified a name attribute on the input elements, so they won't be added to the form's elements array as named elements:

<input type="text" id="VesDiameter" value="0" size="10" onKeyUp="CalcVolume();">

Either give them a name and use the elements array, or (better) use

var vesdiameter = document.getElementById("VesDiameter").value;

which will work on all modern browsers - no branching necessary. Just to be on the safe side, replace that sniffing for a browser version greater than or equal to 4 with a check for getElementById support:

if (document.getElementById) { // NB: no brackets; we're testing for existence of the method, not executing it
    // do stuff...
}

You probably want to validate your input as well; something like

var vesdiameter = parseFloat(document.getElementById("VesDiameter").value);
if (isNaN(vesdiameter)) {
    alert("Diameter should be numeric");
    return;
}

would help.

There are plenty of libraries that can help you with URI building (don't reinvent the wheel). Here are three to get you started:

Java EE 7

import javax.ws.rs.core.UriBuilder;
...
return UriBuilder.fromUri(url).queryParam(key, value).build();

org.apache.httpcomponents:httpclient:4.5.2

import org.apache.http.client.utils.URIBuilder;
...
return new URIBuilder(url).addParameter(key, value).build();

org.springframework:spring-web:4.2.5.RELEASE

import org.springframework.web.util.UriComponentsBuilder;
...
return UriComponentsBuilder.fromUriString(url).queryParam(key, value).build().toUri();

See also: GIST > URI Builder Tests

you can easily iterate in objects

eg: if the object is var a = {a:'apple', b:'ball', c:'cat', d:'doll', e:'elephant'};

Object.keys(a).forEach(key => {
   console.log(key) // returns the keys in an object
   console.log(a[key])  // returns the appropriate value 
})

I did it in my project ,

make a div with back ground url as gif , which is nothing but animation gif

<div class="busyindicatorClass"> </div>

.busyindicatorClass
{
background-url///give animation here
}

in your ajax call , add this class to the div and in ajax success remove the class.

it will do the trick thatsit.

let me know if you need antthing else , i can give you more details

in the ajax success remove the class

success: function(data) {
    remove class using jquery
  }

Haven't tried it myself, but this page has a list of plugin modules that run in Linux' built in iptables IP filtering system. One of the modules is called "nth", and allows you to set up a rule that will drop a configurable rate of the packets. Might be a good place to start, at least.

If you need a powerful logging library for Node.js, Tracer https://github.com/baryon/tracer is a better choice.

It outputs log messages with a timestamp, file name, method name, line number, path or call stack, support color console, and support database, file, stream transport easily. I am the author.

Your regex looks correct, but you're splitting with it instead of matching with it. You want something like this:

// Untested code
Matcher matcher = Pattern.compile("<%=(.*?)%>").matcher(str);
while (matcher.find()) {
    System.out.println(matcher.group());
}

CSS has different pseudo selector by which you can achieve such effect. In your case you can use

:active : if you want background color only when the button is clicked and don't want to persist.

:focus: if you want background color untill the focus is on the button.

button:active{
    background:olive;
}

and

button:focus{
    background:olive;
}

P.S.: Please don't give the number in Id attribute of html elements.

You can write the following:

Path.Combine(Path.GetParentDirectory(GetType(MyClass).Assembly.Location), "Images\image.jpg")

This typically stems from a bug in revision control system, or similar. This was a product from CVS, if a file was checked in from Windows to Unix server, and then checked out again...

In other words, it is just broken...

try using return 0;

if it keeps failing change your solution platform to 64x instead of 86x and go to configuration manager(that's were you change the 86x to 64x) and in platform set it to 64 bits

that works for me, hope it work to you

You can use the short version:

File.write('/path/to/file', 'Some glorious content')

It returns the length written; see ::write for more details and options.

To append to the file, if it already exists, use:

File.write('/path/to/file', 'Some glorious content', mode: 'a')

display: is not transitionable. You'll probably need to use jQuery to do what you want to do.

I went into wp-config/ and deleted the object-cache.php and advanced-cache.php and it worked fine for me.

...allow use of an ORDER BY in a view definition.

That's not a good idea. A view should never have an ORDER BY defined.

An ORDER BY has an impact on performance - using it a view means that the ORDER BY will turn up in the explain plan. If you have a query where the view is joined to anything in the immediate query, or referenced in an inline view (CTE/subquery factoring) - the ORDER BY is always run prior to the final ORDER BY (assuming it was defined). There's no benefit to ordering rows that aren't the final result set when the query isn't using TOP (or LIMIT for MySQL/Postgres).

Consider:

CREATE VIEW my_view AS
    SELECT i.item_id,
           i.item_description,
           it.item_type_description
      FROM ITEMS i
      JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
  ORDER BY i.item_description

...

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM my_view t
ORDER BY t.item_type_description

...is the equivalent to using:

  SELECT t.item_id,
         t.item_description,
         t.item_type_description
    FROM (SELECT i.item_id,
                 i.item_description,
                 it.item_type_description
            FROM ITEMS i
            JOIN ITEM_TYPES it ON it.item_type_id = i.item_type_id
        ORDER BY i.item_description) t
ORDER BY t.item_type_description

This is bad because:

1. The example is ordering the list initially by the item description, and then it's reordered based on the item type description. It's wasted resources in the first sort - running as is does not mean it's running: ORDER BY item_type_description, item_description
2. It's not obvious what the view is ordered by due to encapsulation. This does not mean you should create multiple views with different sort orders...

Bless is a high quality, full featured hex editor.

It is written in mono/Gtk# and its primary platform is GNU/Linux. However it should be able to run without problems on every platform that mono and Gtk# run.

Bless currently provides the following features:

• Efficient editing of large data files and block devices.
• Multilevel undo - redo operations.
• Customizable data views.
• Fast data rendering on screen.
• Multiple tabs.
• Fast find and replace operations.
• A data conversion table.
• Advanced copy/paste capabilities.
• Highlighting of selection pattern matches in the file.
• Plugin based architecture.
• Export of data to text and html (others with plugins).
• Bitwise operations on data.
• A comprehensive user manual.

wxHexEditor is another Free Hex Editor, built because there is no good hex editor for Linux system, specially for big files.

• It uses 64 bit file descriptors (supports files or devices up to 2^64 bytes , means some exabytes but tested only 1 PetaByte file (yet). ).
• It does NOT copy whole file to your RAM. That make it FAST and can open files (which sizes are Multi Giga < Tera < Peta < Exabytes)
• Could open your devices on Linux, Windows or MacOSX.
• Memory Usage : Currently ~10 MegaBytes while opened multiple > ~8GB files.
• Could operate thru XOR encryption.
• Written with C++/wxWidgets GUI libs and can be used with other OSes such as Mac OS, Windows as native application.
• You can copy/edit your Disks, HDD Sectors with it.( Usefull for rescue files/partitions by hand. )
• You can delete/insert bytes to file, more than once, without creating temp file.

DHEX is a more than just another hex editor: It includes a diff mode, which can be used to easily and conveniently compare two binary files. Since it is based on ncurses and is themeable, it can run on any number of systems and scenarios. With its utilization of search logs, it is possible to track changes in different iterations of files easily. Wikipedia article

You can sort on Linux to find some more here: http://en.wikipedia.org/wiki/Comparison_of_hex_editors

If you are starting IPython with the --pylab option, you shouldn't need to call show() or draw(). Try this:

ipython  --pylab=inline

The same error appears if you do not use the correct (numeric) format of your data in your data.frame column using mean() function. Therefore, check your data using str(data.frame&column) function to see what data type you have, and convert it to numeric format if necessary. For example, if your data is Character convert it with as.numeric(data.frame$column), or as a factor with as.numeric(as.character(data.frame$column)). The mean function does not work with types other than numeric.

All the random methods end up calling random.random() so the best way is to call it directly:

[int(1000*random.random()) for i in xrange(10000)]

For example,

• random.randint calls random.randrange.
• random.randrange has a bunch of overhead to check the range before returning istart + istep*int(self.random() * n).

NumPy is much faster still of course.

You can't have cells of arbitrarily different widths, this is generally a standard behaviour of tables from any space, e.g. Excel, otherwise it's no longer a table but just a list of text.

You can however have cells span multiple columns, such as:

<table>
    <tr>
        <td>25</td>
        <td>50</td>
        <td>25</td>
    </tr>
    <tr>
        <td colspan="2">75</td>
        <td>20</td>
    </tr>
</table>

As an aside, you should avoid using style attributes like border and bgcolor and prefer CSS for those.

add multiDexEnabled true in default config file of build.gradle like this

    defaultConfig {

Please add try catch also in your code so that you can be sure that there in no exception.

try {
    $hostname = "servername";
    $dbname = "dbname";
    $username = "username";
    $pw = "password";
    $pdo = new PDO ("mssql:host=$hostname;dbname=$dbname","$username","$pw");
  } catch (PDOException $e) {
    echo "Failed to get DB handle: " . $e->getMessage() . "\n";
    exit;
  }

In the project I'm working on, audit log also started from the very minimalistic design, like the one you described:

event ID
event date/time
event type
user ID
description

The idea was the same: to keep things simple.

However, it quickly became obvious that this minimalistic design was not sufficient. The typical audit was boiling down to questions like this:

Who the heck created/updated/deleted a record 
with ID=X in the table Foo and when?

So, in order to be able to answer such questions quickly (using SQL), we ended up having two additional columns in the audit table

object type (or table name)
object ID

That's when design of our audit log really stabilized (for a few years now).

Of course, the last "improvement" would work only for tables that had surrogate keys. But guess what? All our tables that are worth auditing do have such a key!

There's no reason to use / as the separator in sed. But if you really wanted to:

sed 's/\\/\//g'

I suggest you to use provider. Provide is good when you want to configure it first before to use (against Service/Factory)

Something like:

.provider('Magazines', function() {

    this.url = '/';
    this.urlArray = '/';
    this.organId = 'Default';

    this.$get = function() {
        var url = this.url;
        var urlArray = this.urlArray;
        var organId = this.organId;

        return {
            invoke: function() {
                return ......
            }
        }
    };

    this.setUrl  = function(url) {
        this.url = url;
    };

   this.setUrlArray  = function(urlArray) {
        this.urlArray = urlArray;
    };

    this.setOrganId  = function(organId) {
        this.organId = organId;
    };
});

.config(function(MagazinesProvider){
    MagazinesProvider.setUrl('...');
    MagazinesProvider.setUrlArray('...');
    MagazinesProvider.setOrganId('...');
});

And now controller:

function MyCtrl($scope, Magazines) {        

        Magazines.invoke();

       ....

}

I assume you have already read Wikipedia and other academic resources on this, so I won't recycle any of that information. I must also caveat that I am not a computer science expert by any means, but I'll share my two cents on my understanding of these topics...

Dynamic Programming

Breaks the problem down into discrete subproblems. The recursive algorithm for the Fibonacci sequence is an example of Dynamic Programming, because it solves for fib(n) by first solving for fib(n-1). In order to solve the original problem, it solves a different problem.

Divide and Conquer

These algorithms typically solve similar pieces of the problem, and then put them together at the end. Mergesort is a classic example of divide and conquer. The main difference between this example and the Fibonacci example is that in a mergesort, the division can (theoretically) be arbitrary, and no matter how you slice it up, you are still merging and sorting. The same amount of work has to be done to mergesort the array, no matter how you divide it up. Solving for fib(52) requires more steps than solving for fib(2).

First you need to define the List as :

List<Map<String, ArrayList<String>>> list = new ArrayList<>();

To add the Map to the List , use add(E e) method :

list.add(map);

d = {"name":"interpolator",
     "children":[{'name':key,"size":value} for key,value in sample.items()]}
json_string = json.dumps(d)

Of course, it's unlikely that the order will be exactly preserved ... But that's just the nature of dictionaries ...

If you're just after console logging here's what I'd do:

export default class App extends Component {
  componentDidMount() {
    console.log('I was triggered during componentDidMount')
  }

  render() {
    console.log('I was triggered during render')
    return ( 
      <div> I am the App component </div>
    )
  }
}

Shouldn't be any need for those packages just to do console logging.

1) Your existing web.config: you have declared rewrite map .. but have not created any rules that will use it. RewriteMap on its' own does absolutely nothing.

2) Below is how you can do it (it does not utilise rewrite maps -- rules only, which is fine for small amount of rewrites/redirects):

This rule will do SINGLE EXACT rewrite (internal redirect) /page to /page.html. URL in browser will remain unchanged.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRewrite" stopProcessing="true">
                <match url="^page$" />
                <action type="Rewrite" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

This rule #2 will do the same as above, but will do 301 redirect (Permanent Redirect) where URL will change in browser.

<system.webServer>
    <rewrite>
        <rules>
            <rule name="SpecificRedirect" stopProcessing="true">
                <match url="^page$" />
                <action type="Redirect" url="/page.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Rule #3 will attempt to execute such rewrite for ANY URL if there are such file with .html extension (i.e. for /page it will check if /page.html exists, and if it does then rewrite occurs):

<system.webServer>
    <rewrite>
        <rules>
            <rule name="DynamicRewrite" stopProcessing="true">
                <match url="(.*)" />
                <conditions>
                    <add input="{REQUEST_FILENAME}\.html" matchType="IsFile" />
                </conditions>
                <action type="Rewrite" url="/{R:1}.html" />
            </rule>
        </rules>
    </rewrite>
</system.webServer>

Erik Aigner,

Please use $dirty(The field has been modified) and $invalid (The field content is not valid).

Please check below examples for angular form validation

1)

Validation example HTML for user enter inputs:

<form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate>
  <p>Email:<br>
    <input type="email" name="email" ng-model="email" required>
    <span ng-show="myForm.email.$dirty && myForm.email.$invalid">
      <span ng-show="myForm.email.$error.required">Email is required.</span>
      <span ng-show="myForm.email.$error.email">Invalid email address.</span>
      </span>
  </p>
    </form>

2)

Validation example HTML/Js for user submits :

      <form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate form-submit-validation="">
      <p>Email:<br>
        <input type="email" name="email" ng-model="email" required>

                            $event.preventDefault();
                        }
                        scope.$apply(function () {
                            scope.submitted = true;
                        });


                    });
                }
            }
        };


  })

you don't want use directive use ng-change function like below

  <form  ng-app="myApp"  ng-controller="validateCtrl" name="myForm" novalidate ng-change="submitFun()">
      <p>Email:<br>
        <input type="email" name="email" ng-model="email" required>
        <span ng-show="submitted || myForm.email.$dirty && myForm.email.$invalid">
          <span ng-show="myForm.email.$error.required">Email is required.</span>
          <span ng-show="myForm.email.$error.email">Invalid email address.</span>
          </span>
      </p>
<p>
  <input type="submit">
</p>
</form>

Controller SubmitFun() JS:

 var app = angular.module('example', []);
 app.controller('exampleCntl', function($scope) {
 $scope.submitFun = function($event) {
 $scope.submitted = true;
  if (!$scope.myForm.$valid) 
  {
        $event.preventDefault();
   }
  }

});

Traversal over the large map entrySet() is much better than the keySet(). Check this tutorial how they optimise the traversal over the large object with the help of entrySet() and how it helps for performance tuning.

Here's a solution if you just want to update certain components on a page:

In template

<Component1 :key="forceReload" />
<Component2 :key="forceReload" />

In data

data() {
  return {
    forceReload: 0
  {
}

In methods:

   Methods: {
     reload() {
        this.forceReload += 1
     }
   }

Use a unique key and bind it to a data property for each one you want to update (I typically only need this for a single component, two at the most. If you need more, I suggest just refreshing the full page using the other answers.

I learned this from Michael Thiessen's post: https://medium.com/hackernoon/the-correct-way-to-force-vue-to-re-render-a-component-bde2caae34ad

In my case, it was because of exception inside the constructor of my injected dependency (in your example - inside DashboardRepository constructor). The exception was caught somewhere inside MVC infrastructure. I found this after I added logs in relevant places.

The following suggestion let's you test abstract classes without creating a "real" subclass - the Mock is the subclass.

use Mockito.mock(My.class, Mockito.CALLS_REAL_METHODS), then mock any abstract methods that are invoked.

Example:

public abstract class My {
  public Result methodUnderTest() { ... }
  protected abstract void methodIDontCareAbout();
}

public class MyTest {
    @Test
    public void shouldFailOnNullIdentifiers() {
        My my = Mockito.mock(My.class, Mockito.CALLS_REAL_METHODS);
        Assert.assertSomething(my.methodUnderTest());
    }
}

Note: The beauty of this solution is that you do not have to implement the abstract methods, as long as they are never invoked.

In my honest opinion, this is neater than using a spy, since a spy requires an instance, which means you have to create an instantiatable subclass of your abstract class.

Take a pointer to the first element instead:

process_data (&something [0]);

https://github.com/praeclarum/sqlite-net is now probably the best option.

I had a similar issue. Renato's tip worked for me. I used a older version of java class files (under WEB-INF/classes folder) and the problem disappeared. So, it should have been the compiler version mismatch.

You are able to cut all odd/even columns by using seq:

This would print all odd columns

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)

To print all even columns you could use

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)

By changing the second number of seq you can specify which columns to be printed.

If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)

This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.

To change a cell value using a column name, one can use

iris$Sepal.Length[3]=999

Since there are Small object heap(SOH) and Large object heap(LOH)

We can call GC.Collect() to clear de-reference object in SOP, and move lived object to next generation.

In .net4.5, we can also compact LOH by using largeobjectheapcompactionmode
