The header <math.h> is a C std lib header. It defines a lot of stuff in the global namespace. The header <cmath> is the C++ version of that header. It defines essentially the same stuff in namespace std. (There are some differences, like that the C++ version comes with overloads of some functions, but that doesn't matter.) The header <cmath.h> doesn't exist.

Since vendors don't want to maintain two versions of what is essentially the same header, they came up with different possibilities to have only one of them behind the scenes. Often, that's the C header (since a C++ compiler is able to parse that, while the opposite won't work), and the C++ header just includes that and pulls everything into namespace std. Or there's some macro magic for parsing the same header with or without namespace std wrapped around it or not. To this add that in some environments it's awkward if headers don't have a file extension (like editors failing to highlight the code etc.). So some vendors would have <cmath> be a one-liner including some other header with a .h extension. Or some would map all includes matching <cblah> to <blah.h> (which, through macro magic, becomes the C++ header when __cplusplus is defined, and otherwise becomes the C header) or <cblah.h> or whatever.

That's the reason why on some platforms including things like <cmath.h>, which ought not to exist, will initially succeed, although it might make the compiler fail spectacularly later on.

I have no idea which std lib implementation you use. I suppose it's the one that comes with GCC, but this I don't know, so I cannot explain exactly what happened in your case. But it's certainly a mix of one of the above vendor-specific hacks and you including a header you ought not to have included yourself. Maybe it's the one where <cmath> maps to <cmath.h> with a specific (set of) macro(s) which you hadn't defined, so that you ended up with both definitions.

Note, however, that this code still ought not to compile:

#include <cmath>

double f(double d)
{
  return abs(d);
}

There shouldn't be an abs() in the global namespace (it's std::abs()). However, as per the above described implementation tricks, there might well be. Porting such code later (or just trying to compile it with your vendor's next version which doesn't allow this) can be very tedious, so you should keep an eye on this.

A stateful server keeps state between connections. A stateless server does not.

So, when you send a request to a stateful server, it may create some kind of connection object that tracks what information you request. When you send another request, that request operates on the state from the previous request. So you can send a request to "open" something. And then you can send a request to "close" it later. In-between the two requests, that thing is "open" on the server.

When you send a request to a stateless server, it does not create any objects that track information regarding your requests. If you "open" something on the server, the server retains no information at all that you have something open. A "close" operation would make no sense, since there would be nothing to close.

HTTP and NFS are stateless protocols. Each request stands on its own.

Sometimes cookies are used to add some state to a stateless protocol. In HTTP (web pages), the server sends you a cookie and then the browser holds the state, only to send it back to the server on a subsequent request.

SMB is a stateful protocol. A client can open a file on the server, and the server may deny other clients access to that file until the client closes it.

Can the problem be with the "a.mProperty > b.mProperty" line? I've gotten the following code to work:

#include <algorithm>
#include <vector>
#include <iterator>
#include <iostream>
#include <sstream>

struct Foo
{
    Foo() : _i(0) {};

    int _i;

    friend std::ostream& operator<<(std::ostream& os, const Foo& f)
    {
        os << f._i;
        return os;
    };
};

typedef std::vector<Foo> VectorT;

std::string toString(const VectorT& v)
{
    std::stringstream ss;
    std::copy(v.begin(), v.end(), std::ostream_iterator<Foo>(ss, ", "));
    return ss.str();
};

int main()
{

    VectorT v(10);
    std::for_each(v.begin(), v.end(),
            [](Foo& f)
            {
                f._i = rand() % 100;
            });

    std::cout << "before sort: " << toString(v) << "\n";

    sort(v.begin(), v.end(),
            [](const Foo& a, const Foo& b)
            {
                return a._i > b._i;
            });

    std::cout << "after sort:  " << toString(v) << "\n";
    return 1;
};

The output is:

before sort: 83, 86, 77, 15, 93, 35, 86, 92, 49, 21,
after sort:  93, 92, 86, 86, 83, 77, 49, 35, 21, 15,

const date = moment(YOUR_DATE)
return (moment().diff(date, 'days') >= 2) ? date.fromNow() : date.calendar().split(' ')[0]

Starting with PHP 5.6, you can define constant arrays using const keyword like below

const DEFAULT_ROLES = ['test', 'development', 'team'];

and different elements can be accessed as below:

echo DEFAULT_ROLES[1]; 
....

Starting with PHP 7, constant arrays can be defined using define as below:

define('DEFAULT_ROLES', [
    'test',
    'development',
    'team'
]);

and different elements can be accessed same way as before.

HashMap regs = (HashMap) parser.parse(stringjson);

(String)((HashMap)regs.get("firstlevelkey")).get("secondlevelkey");

Two awesome solutions were this, if your extending ListFragment from a fragment, know that mListView.setOnItemClickListener wont be called before your activity is created, this ensured it is set when activity has been created

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    mListView.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long rowId) {
            // Do the onItemClick action

            Log.d("ROWSELECT", "" + rowId);
        }
    });
}

While looking at the source code for ListFragment, I came across this

public class ListFragment extends Fragment {
    ...........................................
    ................................................

    final private AdapterView.OnItemClickListener mOnClickListener
                = new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            onListItemClick((ListView)parent, v, position, id);
        }
    };

    ................................................................
    ................................................................

    public void onListItemClick(ListView l, View v, int position, long id) {
    }
}

An onItemClickListener object is attached and it calls onListItemClick() As such the other similar solution, which works in the exact same way is to override onListItemClick()

@Override
public void onListItemClick(ListView l, View v, int position, long rowId) {
    super.onListItemClick(l, v, position, id);
   // Do the onItemClick action

   Log.d("ROWSELECT", "" + rowId);
} 

If you use a current version of m2eclipse (which you should if you use eclipse and maven):

Select the menu entry

Navigate -> Open Maven POM

and enter the artifact you are looking for.

The pom will open in the pom editor, from which you can select the tab Dependency Hierarchy to view the dependency hierarchy (as the name suggests :-) )

nobody seems to have recommended noHistory="true" in manifest.xml to prevent certain activity to appear after you press back button which by default calling method finish()

Had same issue, after installing java using below lines solved the issue !

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

This is a one line solution involving LINQ.

var elements = new String[] { "1", "2", "3" };
Foo(elements.Cast<object>().ToArray())

For many of the sites I build the client will ask for a 100vh banner and just as you have found, it results in a bad "jumpy" experience on mobile when you begin to scroll. This is how I solve the problem for a smooth consistent experience across all devices:

I first set my banner element CSS to height:100vh

Then I use jQuery to get the height in pixels of my banner element and apply an inline style using this height.

var viewportHeight = $('.banner').outerHeight();
$('.banner').css({ height: viewportHeight });

Doing this solves the issue on mobile devices as when the page loads, the banner element is set to 100vh using CSS and then jQuery overrides this by putting inline CSS on my banner element which stops it from resizing when a user begins to scroll.

However, on desktop if a user resizes their browser window my banner element won't resize because it now has a fixed height set in pixels due to the above jQuery. To address this I use Mobile Detect to add a 'mobile' class to the body of my document. And then I wrap the above jQuery in an if statement:

if ($('body').hasClass('mobile')) {
  var viewportHeight = $('.banner').outerHeight();
  $('.banner').css({ height: viewportHeight });
}

As a result, if a user is on a mobile device the class 'mobile' is present on the body of my page and the above jQuery is executed. So my banner element will only get the inline CSS applied on mobile devices meanwhile on desktop the original 100vh CSS rule remains in place.

You can use *args and **kwargs syntax for variable length arguments.

What do *args and **kwargs mean?

And from the official python tutorial

http://docs.python.org/dev/tutorial/controlflow.html#more-on-defining-functions

I know this is old, but here is a additional thing if you still encounter problems with the solution above.

Just put in your <head> :

<meta http-equiv="X-UA-Compatible" content="IE=edge"> 

It will prevent IE to jump back to IE9 compatibility, thus breaking the video function. Worked for me, so if you still have problems, consider checking this out.

Alternatively you can add this in PHP :

header('x-ua-compatible: ie=edge');

Or in a .htaccess file:

header set X-UA-Compatible "IE=Edge"

In C#/.NET 3.5 you could write a little program to do:

using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
    string controller = context.ConnectedServer;
    Console.WriteLine( "Domain Controller:" + controller );
} 

This will list all the users in the current domain:

using (PrincipalContext context = new PrincipalContext(ContextType.Domain))
{
    using (UserPrincipal searchPrincipal = new UserPrincipal(context))
    {
       using (PrincipalSearcher searcher = new PrincipalSearcher(searchPrincipal))
       {
           foreach (UserPrincipal principal in searcher.FindAll())
           {
               Console.WriteLine( principal.SamAccountName);
           }
       }
    }
}

a <- 1:120
b <- a[seq(1, length(a), 6)]

Try this:

onclick="myfunction(
    '/myController/myAction',
    function(){myfuncionOnOK('/myController2/myAction2','myParameter2');},
    function(){myfuncionOnCancel('/myController3/myAction3','myParameter3');}
);"

Then you just need to call these two functions passed to myfunction:

function myfunction(url, f1, f2) {
    // …
    f1();
    f2();
}

In VBA we can not use if jj = 5 or 6 then we must use if jj = 5 or jj = 6 then

maybe this:

If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then

The most flexible way is to use a custom Git command. For example, create the following Python script somewhere in your $PATH under the name git-rmbranch and make it executable:

#!/usr/bin/env python3

import argparse
import subprocess
import sys

def rmbranch(branch_name, remote, force):
    try:
        print(subprocess.run(['git', 'branch', '-D' if force else '-d', branch_name],
                             capture_output=True, check=True, encoding='utf-8').stdout, end='')
    except subprocess.CalledProcessError as exc:
        print(exc.stderr.replace(f'git branch -D {branch_name}', f'git rmbranch -f {branch_name}'), end='')
        return exc.returncode

    return subprocess.run(['git', 'push', remote, '--delete', branch_name]).returncode    

if __name__ == '__main__':
    parser = argparse.ArgumentParser(description='Delete a Git branch locally and remotely.')
    parser.add_argument('-r', '--remote', default='origin', help="The remote name (defaults to 'origin')")
    parser.add_argument('-f', '--force', action='store_true', help='Force deletion of not fully merged branches')
    parser.add_argument('branch_name', help='The branch name')
    args = parser.parse_args()

    sys.exit(rmbranch(args.branch_name, args.remote, args.force))

Then git rmbranch -h will show you usage information:

usage: git-rmbranch [-h] [-r REMOTE] [-f] branch_name

Delete a Git branch locally and remotely.

positional arguments:
  branch_name           The branch name

optional arguments:
  -h, --help            show this help message and exit
  -r REMOTE, --remote REMOTE
                        The remote name (defaults to 'origin')
  -f, --force           Force deletion of not fully merged branches

Note that git push origin --delete <branch_name> also removes the local remote-tracking branch (origin/<branch_name> by default), so no need to care about that.

P.S. You can find the latest version of this Git command here. Comments and suggestions are welcome.

It represents the speed of an algorithm in the long run.

To take a literal analogy, you don't care how fast a runner can sprint a 100m dash, or even a 5k run. You care more about marathoners, and preferably ultra marathoners (beyond which the analogy to running breaks down and you have to revert to the metaphorical meaning of "the long run").

You can safely stop reading here.

I'm adding this answer because I'm surprised how mathematical and technical the rest of the answers are. The notion of the "long run" in first sentence is related to the arbitrarily time-consuming computational tasks. Unlike running, which is limited by human capacity, computational tasks can take even more than millions of years for certain algorithms to complete.

What about all those mathematical logarithms and polynomials? It turns out that algorithms are intrinsically related to these mathematical terms. If you are measuring the heights of all the kids on the block, it will take you as much time as there are kids. This is intrinsically related to the notion of n^1 or just n where n is nothing more than the number of kids on the block. In the ultra-marathon case, you are measuring the heights of all the kids in your city, but you then have to ignore travel times and assume they are all available to you in a line (otherwise we jump ahead of the current explanation).

Suppose then you are trying to arrange the list that you made of of kids heights in order of shortest height to longest height. If it is just the kids in your neighborhood you might just eyeball it and come up with the ordered list. This is the "sprint" analogy, and we truly don't care about sprints in computer science because why use a computer when you can eyeball something?

But if you were arranging the list of the heights of all kids in your city, or better yet, your country, then you will find that how you do it is intrinsically tied to the mathematical log and n^2. Going through your list to find the shortest kid, writing his name in a separate notebook, and crossing it out from the original notebook is intrinsically tied to the mathematical n^2. If you think of arranging half your notebook, then the other half, and then combining the results, you will arrive at a method that is intrinsically tied to the logarithm.

Finally, suppose you first had to go to the store to buy a measuring tape. This is an example of an effort that is of consequence in short sprints, such as measuring the kids on the block, but when you are measuring all the kids in the city you can safely ignore this cost. This is the intrinsic connection to the mathematical dropping of say lower order polynomial terms.

I hope I have explained that the big-O notation is merely about the long run, that the mathematics is inherently connected to ways of computation, and that the dropping of mathematical terms and other simplifications are connected to the long run in a rather common sense way.

Once you realize this, you'll find the big-O is really super-easy because all the hard high school math just drops out easily. The only difficult part is analyzing an algorithm to identify the mathematical terms, but with some practice you can start dropping terms during the analysis itself and safely ignore chunks of the algorithm to focus only on the part that is relevant to the big-O. I. e. you should be able to eyeball most situations.

Happy big-O-ing, it was my favorite thing about Computer Science -- finding that something was way easier than I thought, and then being able to show off at Google interviews when the uninitiated would be intimidated, lol.

It's actually working quite good with:

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

This will create a list with importable module names.

In Python3 I came up with type (f) == type (lambda x:x) which yields True if f is a function and False if it is not. But I think I prefer isinstance (f, types.FunctionType), which feels less ad hoc. I wanted to do type (f) is function, but that doesn't work.

This answer should be enough to get you set up to follow this tutorial on Building a functional search component with MongoDB, Elasticsearch, and AngularJS.

If you're looking to use faceted search with data from an API then Matthiasn's BirdWatch Repo is something you might want to look at.

So here's how you can setup a single node Elasticsearch "cluster" to index MongoDB for use in a NodeJS, Express app on a fresh EC2 Ubuntu 14.04 instance.

Make sure everything is up to date.

sudo apt-get update

Install NodeJS.

sudo apt-get install nodejs
sudo apt-get install npm

Install MongoDB - These steps are straight from MongoDB docs. Choose whatever version you're comfortable with. I'm sticking with v2.4.9 because it seems to be the most recent version MongoDB-River supports without issues.

Import the MongoDB public GPG Key.

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 7F0CEB10

Update your sources list.

echo 'deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen' | sudo tee /etc/apt/sources.list.d/mongodb.list

Get the 10gen package.

sudo apt-get install mongodb-10gen

Then pick your version if you don't want the most recent. If you are setting your environment up on a windows 7 or 8 machine stay away from v2.6 until they work some bugs out with running it as a service.

apt-get install mongodb-10gen=2.4.9

Prevent the version of your MongoDB installation being bumped up when you update.

echo "mongodb-10gen hold" | sudo dpkg --set-selections

Start the MongoDB service.

sudo service mongodb start

Your database files default to /var/lib/mongo and your log files to /var/log/mongo.

Create a database through the mongo shell and push some dummy data into it.

mongo YOUR_DATABASE_NAME
db.createCollection(YOUR_COLLECTION_NAME)
for (var i = 1; i <= 25; i++) db.YOUR_COLLECTION_NAME.insert( { x : i } )

Now to Convert the standalone MongoDB into a Replica Set.

First Shutdown the process.

mongo YOUR_DATABASE_NAME
use admin
db.shutdownServer()

Now we're running MongoDB as a service, so we don't pass in the "--replSet rs0" option in the command line argument when we restart the mongod process. Instead, we put it in the mongod.conf file.

vi /etc/mongod.conf

Add these lines, subbing for your db and log paths.

replSet=rs0
dbpath=YOUR_PATH_TO_DATA/DB
logpath=YOUR_PATH_TO_LOG/MONGO.LOG

Now open up the mongo shell again to initialize the replica set.

mongo DATABASE_NAME
config = { "_id" : "rs0", "members" : [ { "_id" : 0, "host" : "127.0.0.1:27017" } ] }
rs.initiate(config)
rs.slaveOk() // allows read operations to run on secondary members.

Now install Elasticsearch. I'm just following this helpful Gist.

Make sure Java is installed.

sudo apt-get install openjdk-7-jre-headless -y

Stick with v1.1.x for now until the Mongo-River plugin bug gets fixed in v1.2.1.

wget https://download.elasticsearch.org/elasticsearch/elasticsearch/elasticsearch-1.1.1.deb
sudo dpkg -i elasticsearch-1.1.1.deb

curl -L http://github.com/elasticsearch/elasticsearch-servicewrapper/tarball/master | tar -xz
sudo mv *servicewrapper*/service /usr/local/share/elasticsearch/bin/
sudo rm -Rf *servicewrapper*
sudo /usr/local/share/elasticsearch/bin/service/elasticsearch install
sudo ln -s `readlink -f /usr/local/share/elasticsearch/bin/service/elasticsearch` /usr/local/bin/rcelasticsearch

Make sure /etc/elasticsearch/elasticsearch.yml has the following config options enabled if you're only developing on a single node for now:

cluster.name: "MY_CLUSTER_NAME"
node.local: true

Start the Elasticsearch service.

sudo service elasticsearch start

Verify it's working.

curl http://localhost:9200

If you see something like this then you're good.

{
  "status" : 200,
  "name" : "Chi Demon",
  "version" : {
    "number" : "1.1.2",
    "build_hash" : "e511f7b28b77c4d99175905fac65bffbf4c80cf7",
    "build_timestamp" : "2014-05-22T12:27:39Z",
    "build_snapshot" : false,
    "lucene_version" : "4.7"
  },
  "tagline" : "You Know, for Search"
}

Now install the Elasticsearch plugins so it can play with MongoDB.

bin/plugin --install com.github.richardwilly98.elasticsearch/elasticsearch-river-mongodb/1.6.0
bin/plugin --install elasticsearch/elasticsearch-mapper-attachments/1.6.0

These two plugins aren't necessary but they're good for testing queries and visualizing changes to your indexes.

bin/plugin --install mobz/elasticsearch-head
bin/plugin --install lukas-vlcek/bigdesk

Restart Elasticsearch.

sudo service elasticsearch restart

Finally index a collection from MongoDB.

curl -XPUT localhost:9200/_river/DATABASE_NAME/_meta -d '{
  "type": "mongodb",
  "mongodb": {
    "servers": [
      { "host": "127.0.0.1", "port": 27017 }
    ],
    "db": "DATABASE_NAME",
    "collection": "ACTUAL_COLLECTION_NAME",
    "options": { "secondary_read_preference": true },
    "gridfs": false
  },
  "index": {
    "name": "ARBITRARY INDEX NAME",
    "type": "ARBITRARY TYPE NAME"
  }
}'

Check that your index is in Elasticsearch

curl -XGET http://localhost:9200/_aliases

Check your cluster health.

curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'

It's probably yellow with some unassigned shards. We have to tell Elasticsearch what we want to work with.

curl -XPUT 'localhost:9200/_settings' -d '{ "index" : { "number_of_replicas" : 0 } }'

Check cluster health again. It should be green now.

curl -XGET 'http://localhost:9200/_cluster/health?pretty=true'

Go play.

Now this may include more than you need (and may not even work for command line applications in a non-graphical environment, I don't know), but there is nw.js. It's Blink (i.e. Chromium/Webkit) + io.js (i.e. Node.js).

You can use node-webkit-builder to build native executable binaries for Linux, OS X and Windows.

If you want a GUI, that's a huge plus. You can build one with web technologies. If you don't, specify "node-main" in the package.json (and probably "window": {"show": false} although maybe it works to just have a node-main and not a main)

I haven't tried to use it in exactly this way, just throwing it out there as a possibility. I can say it's certainly not an ideal solution for non-graphical Node.js applications.

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

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

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

I think you need a service that handle the authentication process (and its storage).

In this service you'll need some basic methods :

• isAuthenticated()
• login()
• logout()
• etc ...

This service should be injected in your controllers of each module :

• In your dashboard section, use this service to check if user is authenticated (service.isAuthenticated() method) . if not, redirect to /login
• In your login section, just use the form data to authenticate the user through your service.login() method

A good and robust example for this behavior is the project angular-app and specifically its security module which is based over the awesome HTTP Auth Interceptor Module

Hope this helps

If the name's dynamic, then you must have something like

$arr[$key]

which'd mean that $key contains the value of the key.

You can use array_keys() to get ALL the keys of an array, e.g.

$arr = array('a' => 'b', 'c' => 'd')
$x = array_keys($arr);

would give you

$x = array(0 => 'a', 1 => 'c');

This is worked for me

scroll_view.smoothScrollTo(0,0); // scroll to top of screen

The package js-file-download from github.com/kennethjiang/js-file-download handles edge cases for browser support:

View source to see how it uses techniques mentioned on this page.

Installation

yarn add js-file-download
npm install --save js-file-download

Usage

import fileDownload from 'js-file-download'

// fileDownload(data, filename, mime)
// mime is optional

fileDownload(data, 'filename.csv', 'text/csv')

You are creating those bytes objects yourself:

item['title'] = [t.encode('utf-8') for t in title]
item['link'] = [l.encode('utf-8') for l in link]
item['desc'] = [d.encode('utf-8') for d in desc]
items.append(item)

Each of those t.encode(), l.encode() and d.encode() calls creates a bytes string. Do not do this, leave it to the JSON format to serialise these.

Next, you are making several other errors; you are encoding too much where there is no need to. Leave it to the json module and the standard file object returned by the open() call to handle encoding.

You also don't need to convert your items list to a dictionary; it'll already be an object that can be JSON encoded directly:

class W3SchoolPipeline(object):    
    def __init__(self):
        self.file = open('w3school_data_utf8.json', 'w', encoding='utf-8')

    def process_item(self, item, spider):
        line = json.dumps(item) + '\n'
        self.file.write(line)
        return item

I'm guessing you followed a tutorial that assumed Python 2, you are using Python 3 instead. I strongly suggest you find a different tutorial; not only is it written for an outdated version of Python, if it is advocating line.decode('unicode_escape') it is teaching some extremely bad habits that'll lead to hard-to-track bugs. I can recommend you look at Think Python, 2nd edition for a good, free, book on learning Python 3.

I had this error message:

Error: Can't open display: localhost:13.0

This fixed it for me:

export DISPLAY="localhost:10.0"

You can use this too:

export DISPLAY="127.0.0.1:10.0"

To answer your question, there is no "proper way" to do that. Now if it's just the warning that bothers you, the best way to avoid its proliferation is to wrap the Query.list() method into a DAO :

public class MyDAO {

    @SuppressWarnings("unchecked")
    public static <T> List<T> list(Query q){
        return q.list();
    }
}

This way you get to use the @SuppressWarnings("unchecked") only once.

I also got stucked with same problem so I fixed it like this :

If you are running mongo and nodejs in docker container or in docker compose

so replace localhost with mongo (which is container name in docker in my case) something like this below in your nodejs mongo connection file.

var mongoURI = "mongodb://mongo:27017/<nodejs_container_name>";

var token = string.Empty;
if (Request.Headers.TryGetValue("MyKey",  out headerValues))
{
    token = headerValues.FirstOrDefault();
}

Personally I don't use final on method parameters, because it adds too much clutter to parameter lists. I prefer to enforce that method parameters are not changed through something like Checkstyle.

For local variables I use final whenever possible, I even let Eclipse do that automatically in my setup for personal projects.

I would certainly like something stronger like C/C++ const.

At first use ExecuteScalar

 objConn = new SqlConnection(strConnection);
 objConn.Open();
 objCmd = new SqlCommand(strSQL, objConn);
 object result = cmd.ExecuteScalar();
 if(result == null)
     strLevel = "";
 else 
     strLevel = result.ToString();

Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;

This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79.

Try this for a vertical scrollbar:

overflow-y:scroll;

use this and it works on both the static arrays and dynamically generated arrays.

var array = [12,2,23,324,23,123,4,23,132,23];
var getMaxValue = Math.max.apply(Math, array );

I had the issue when I use trying to find max value from code below

$('#myTabs').find('li.active').prevAll().andSelf().each(function () {
            newGetWidthOfEachTab.push(parseInt($(this).outerWidth()));
        });

        for (var i = 0; i < newGetWidthOfEachTab.length; i++) {
            newWidthOfEachTabTotal += newGetWidthOfEachTab[i];
            newGetWidthOfEachTabArr.push(parseInt(newWidthOfEachTabTotal));
        }

        getMaxValue = Math.max.apply(Math, array);

I was getting 'NAN' when I use

    var max_value = Math.max(12, 21, 23, 2323, 23);

with my code

Use this:

Later than my previous answer, but may be useful anyway; while gRaphaël Charting may be an outdated alternative, a more recent and nicer option may be http://chartjs.org - still without any Flash, with a MIT license, and a recently updated GitHub.

I've been using it myself since my last answer, so now I have some web apps with one and some with the other.

If you are starting a project anew, try with Chart.js first.

It is easy to configure it using your system local zone, Just in your application.rb add this

config.time_zone = Time.now.zone

Then, rails should show you timestamps in your localtime or you can use something like this instruction to get the localtime

Post.created_at.localtime

Nowadays, you should use ERB::Util.url_encode or CGI.escape. The primary difference between them is their handling of spaces:

>> ERB::Util.url_encode("foo/bar? baz&")
=> "foo%2Fbar%3F%20baz%26"

>> CGI.escape("foo/bar? baz&")
=> "foo%2Fbar%3F+baz%26"

CGI.escape follows the CGI/HTML forms spec and gives you an application/x-www-form-urlencoded string, which requires spaces be escaped to +, whereas ERB::Util.url_encode follows RFC 3986, which requires them to be encoded as %20.

See "What's the difference between URI.escape and CGI.escape?" for more discussion.

This can be done. For example with Firefox

There are many ways to get a page from the command line... but it also depends if you want the code source or the page itself:

If you need the code source:

with curl:

curl $url

with wget:

wget -O - $url

but if you want to get what you can see with a browser, lynx can be useful:

lynx -dump $url

I think you can find so many solutions for this little problem, maybe you should read all man pages for those commands. And don't forget to replace $url by your URL :)

Good luck :)

To have multiple Xcode instances installed you can put them to different folders for example /Developer5.0.2/Xcode, but to use them in CI or build environment(command line) you need to setup some environment variables during the build. You can have more instructions here. So it is working not just with beta and fresh release, also it's working for the really old versions, you might need it to use with Marmalade or Unity plugins which is not support the latest Xcode versions yet(some times it's happens).

From the book Working Effectively with Legacy Code:

"If we need to test a private method, we should make it public. If making it public bothers us, in most cases, it means that our class is doing too much and we ought to fix it."

The way to fix it, according to the author, is by creating a new class and adding the method as public.

The author explains further:

"Good design is testable, and design that isn't testable is bad."

So, within these limits, your only real option is to make the method public, either in the current or a new class.

From a comment:

I want to sort each set.

That's easy. For any set s (or anything else iterable), sorted(s) returns a list of the elements of s in sorted order:

>>> s = set(['0.000000000', '0.009518000', '10.277200999', '0.030810999', '0.018384000', '4.918560000'])
>>> sorted(s)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '10.277200999', '4.918560000']

Note that sorted is giving you a list, not a set. That's because the whole point of a set, both in mathematics and in almost every programming language,* is that it's not ordered: the sets {1, 2} and {2, 1} are the same set.

You probably don't really want to sort those elements as strings, but as numbers (so 4.918560000 will come before 10.277200999 rather than after).

The best solution is most likely to store the numbers as numbers rather than strings in the first place. But if not, you just need to use a key function:

>>> sorted(s, key=float)
['0.000000000', '0.009518000', '0.018384000', '0.030810999', '4.918560000', '10.277200999']

For more information, see the Sorting HOWTO in the official docs.

* See the comments for exceptions.

I stumbled upon the same need. And I read a lot on this so, here is my copper on the subject.

If you want your change detection on push, then you would have it when you change a value of an object inside right ? And you also would have it if somehow, you remove objects.

As already said, use of changeDetectionStrategy.onPush

Say you have this component you made, with changeDetectionStrategy.onPush:

<component [collection]="myCollection"></component>

Then you'd push an item and trigger the change detection :

myCollection.push(anItem);
refresh();

or you'd remove an item and trigger the change detection :

myCollection.splice(0,1);
refresh();

or you'd change an attrbibute value for an item and trigger the change detection :

myCollection[5].attribute = 'new value';
refresh();

Content of refresh :

refresh() : void {
    this.myCollection = this.myCollection.slice();
}

The slice method returns the exact same Array, and the [ = ] sign make a new reference to it, triggering the change detection every time you need it. Easy and readable :)

Regards,

you can use instead of click :

$('#whatever').on('touchstart click', function(){ /* do something... */ });

I just created some directories, shared them and mapped using:

net use y: "\\mycomputername\folder with spaces"

So this solution gets "works on my machine" certificate. What error code do you get?

outgoing url in mvc generated based on the current routing schema.

because your Information action method require id parameter, and your route collection has id of your current requested url(/Admin/Information/5), id parameter automatically gotten from existing route collection values.

to solve this problem you should use UrlParameter.Optional:

 <a href="@Url.Action("Information", "Admin", new { id = UrlParameter.Optional })">Add an Admin</a>

Above suggestions are good. But to try to answer your question directly I'd suggest using cpy-cli in a script defined in your package.json.

This example expects node to somewhere on your path. Install cpy-cli as a development dependency:

npm install --save-dev cpy-cli

Then create a couple of nodejs files. One to do the copy and the other to display a checkmark and message.

copy.js

#!/usr/bin/env node

var shelljs = require('shelljs');
var addCheckMark = require('./helpers/checkmark');
var path = require('path');

var cpy = path.join(__dirname, '../node_modules/cpy-cli/cli.js');

shelljs.exec(cpy + ' /static/* /build/', addCheckMark.bind(null, callback));

function callback() {
  process.stdout.write(' Copied /static/* to the /build/ directory\n\n');
}

checkmark.js

var chalk = require('chalk');

/**
 * Adds mark check symbol
 */
function addCheckMark(callback) {
  process.stdout.write(chalk.green(' ?'));
  callback();
}

module.exports = addCheckMark;

Add the script in package.json. Assuming scripts are in <project-root>/scripts/

...
"scripts": {
  "copy": "node scripts/copy.js",
...

To run the sript:

npm run copy

Use the script below, and switch the DatabaseName with then name of the database that you've backed up. On the column physical_device_name, you'll have the full path of your backed-up database:

select a.backup_set_id, a.server_name, a.database_name, a.name, a.user_name, a.position, a.software_major_version, a.backup_start_date, backup_finish_date, a.backup_size, a.recovery_model, b.physical_device_name
from msdb.dbo.backupset a join msdb.dbo.backupmediafamily b
  on a.media_set_id = b.media_set_id
where a.database_name = 'DatabaseName'
order by a.backup_finish_date desc

Despite having all the appropriate using statements, calling Close, having some exponential back off logic and recreating the TcpClient I've still been seeing issues where the application cannot recover the TCP connection without an application restart. It keeps failing with a System.IO.IOException: Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

But there is an option LingerState on the TcpClient that appears it may have solved the issue (might not know for a few months as my own hardware setup only fails about that often!). See MSDN.

// This discards any pending data and Winsock resets the connection.
LingerOption lingerOption = new LingerOption(true, 0);

using (var tcpClient = new TcpClient 
       {SendTimeout = 2000, ReceiveTimeout = 2000, LingerState = lingerOption })
   ...

I tried another way

Say the table has values

    1   M510
    2   M615
    3   M515
    4   M612
    5   M510MM
    6   M615NN
    7   M515OO
    8   M612PP
    9   A
    10  B
    11  C
    12  D

Here cols 1 to 8 are valid while the rest of them are invalid

  SELECT COL_VAL
    FROM SO_LIKE_TABLE SLT
   WHERE (SELECT DECODE(SUM(CASE
                              WHEN INSTR(SLT.COL_VAL, COLUMN_VALUE) > 0 THEN
                               1
                              ELSE
                               0
                            END),
                        0,
                        'FALSE',
                        'TRUE')
            FROM TABLE(SYS.DBMS_DEBUG_VC2COLl('M510', 'M615', 'M515', 'M612'))) =
         'TRUE'

What I have done is using the INSTR function, I have tried to find is the value in table matches with any of the values as input. In case it does, it will return it's index, i.e. greater than ZERO. In case the table's value does not match with any of the input, then it will return ZERO. This index I have added up, to indicate successful match.

It seems to be working.

Hope it helps.

An old stupid trick that works in this case... paste code from your editor to ms notepad, then viceversa, and evil character will disappears ! I take inspiration from wyisyg/msword copypaste problem. Notepad++ utf-8 w/out BOM works as well.

If anyone is looking for a rowspan on both the left AND on the right, here is how you can do it:

table { _x000D_
    border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
    padding: 20px; _x000D_
    border: 1px solid black; _x000D_
    text-align: center;_x000D_
}

<table>_x000D_
    <tbody>_x000D_
    <tr>_x000D_
        <td rowspan="2">LEFT</td>_x000D_
        <td> 1 </td>_x000D_
        <td> 2 </td>_x000D_
        <td> 3 </td>_x000D_
        <td> 4 </td>_x000D_
        <td rowspan="2">RIGHT</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 5 </td>_x000D_
        <td> 6 </td>_x000D_
        <td> 7 </td>_x000D_
        <td> 8 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
    </tr>_x000D_
    </tbody>_x000D_
</table>

Alternatively, if you want to add the LEFT and RIGHT to an existing rowset, you can achieve the same result by throwing them in with a collapsed colspan in between:

table {_x000D_
    border-collapse: collapse;_x000D_
}_x000D_
_x000D_
td {_x000D_
    padding: 20px; _x000D_
    border: 1px solid black; _x000D_
    text-align: center;_x000D_
}

<table>_x000D_
    <tbody>_x000D_
    <tr>_x000D_
        <td rowspan="3">LEFT</td>_x000D_
        <td colspan="4" style="padding: 0; border-bottom: solid 1px transparent;"></td>_x000D_
        <td rowspan="3">RIGHT</td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 1 </td>_x000D_
        <td> 2 </td>_x000D_
        <td> 3 </td>_x000D_
        <td> 4 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> 5 </td>_x000D_
        <td> 6 </td>_x000D_
        <td> 7 </td>_x000D_
        <td> 8 </td>_x000D_
    </tr>_x000D_
    <tr>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
        <td> - </td>_x000D_
    </tr>_x000D_
    </tbody>_x000D_
</table>

Go to file Global.asax.cs in your project and add the following code.

    protected void Application_BeginRequest()
    {
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.Cache.SetExpires(DateTime.Now.AddHours(-1));
        Response.Cache.SetNoStore();
    }

It worked for me..! Reference link Clear session on Logout MVC 4

For a matrix you can use this:

[M,I] = max(A(:))

I is the index of A(:) containing the largest element.

Now, use the ind2sub function to extract the row and column indices of A corresponding to the largest element.

[I_row, I_col] = ind2sub(size(A),I)

  str = str.replace(/"/g, """);
  str = str.replace(/'/g, "'");
  str = str.replace(/</g, "&lt;");
  str = str.replace(/>/g, "&gt;");
  }
 return str;
 }

You can not make reference to static variable from non-static method. To understand this , you need to understand the difference between static and non-static.

Static variables are class variables , they belong to class with their only one instance , created at the first only. Non-static variables are initialized every time you create an object of the class.

Now coming to your question, when you use new() operator we will create copy of every non-static filed for every object, but it is not the case for static fields. That's why it gives compile time error if you are referencing a static variable from non-static method.

Simple solution:

<style>
.center {
    margin: auto;

}
</style>

<div class="center">
    <p> somthing goes here </p>
</div>

Try Online

Method 1:

If the method DoSomethingBeta was static you need only call:

Beta.DoSomethingBeta();

Method 2:

If Alpha extends from Beta you could call DoSomethingBeta() directly.

public class Alpha extends Beta{
     public void DoSomethingAlpha() {
          DoSomethingBeta();  //?
     }
}

Method 3:

Alternatively you need to have access to an instance of Beta to call the methods from it.

public class Alpha {
     public void DoSomethingAlpha() {
          Beta cbeta = new Beta();
          cbeta.DoSomethingBeta();  //?
     }
}

Incidentally is this homework?

WITH (NOLOCK) is the equivalent of using READ UNCOMMITED as a transaction isolation level. So, you stand the risk of reading an uncommitted row that is subsequently rolled back, i.e. data that never made it into the database. So, while it can prevent reads being deadlocked by other operations, it comes with a risk. In a banking application with high transaction rates, it's probably not going to be the right solution to whatever problem you're trying to solve with it IMHO.

You should give an object as argument

userModel.count({name: "sam"});

or

userModel.count({name: "sam"}).exec(); //if you are using promise

or

userModel.count({}); // if you want to get all counts irrespective of the fields

On the recent version of mongoose, count() is deprecated so use

userModel.countDocuments({name: "sam"});

I found this on google, tested in Excel 2003 & it works for me:

=IF(COUNTIF(A1,"* *"),RIGHT(A1,LEN(A1)-LOOKUP(LEN(A1),FIND(" ",A1,ROW(INDEX($A:$A,1,1):INDEX($A:$A,LEN(A1),1))))),A1)

[edit] I don't have enough rep to comment, so this seems the best place...BradC's answer also doesn't work with trailing spaces or empty cells...
[2nd edit] actually, it doesn't work for single words either...

In case someone else runs into this problem, I just did using Eclipse; running the project via the right click action. This error occurred in the J2EE view, but did NOT occur in the Java view. Not sure - assuming something with adding libraries to the correct 'lib' directory.

I am also using a Maven project, allowing m2eclipse to manage dependancies.

To avoid nesting and ngSwitch, there is also this possibility, which leverages the way logical operators work in Javascript:

<ng-container *ngIf="foo === 1; then first; else (foo === 2 && second) || (foo === 3 && third)"></ng-container>
  <ng-template #first>First</ng-template>
  <ng-template #second>Second</ng-template>
  <ng-template #third>Third</ng-template>

In some situations we have to get image from drawable or raw folder using image name instead if generated id

// Image View Object 
        mIv = (ImageView) findViewById(R.id.xidIma);
// create context Object for  to Fetch  image from resourse 
Context mContext=getApplicationContext();

// getResources().getIdentifier("image_name","res_folder_name", package_name);

// find out below example 
    int i = mContext.getResources().getIdentifier("ic_launcher","raw", mContext.getPackageName());

// now we will get contsant id for that image       
        mIv.setBackgroundResource(i);

Here is another example, for compiling a java file in a nested directory.

I was trying to build this from the command line. This is an example from 'gradle', which has dependency 'commons-collection.jar'. For more info, please see 'gradle: java quickstart' example. -- of course, you would use the 'gradle' tools to build it. But i thought to extend this example, for a nested java project, with a dependent jar.

Note: You need the 'gradle binary or source' distribution for this, example code is in: 'samples/java/quickstart'

% mkdir -p temp/classes
% curl --get \
    http://central.maven.org/maven2/commons-collections/commons-collections/3.2.2/commons-collections-3.2.2.jar \

you can use ES5 some. Its pretty first by using callback

function findRestaurent(foodType) {
    var restaurant;
    restaurants.some(function (r) {
        if (r.food === id) {
            restaurant = r;
            return true;

Not that I know of, unless you select from INFORMATION_SCHEMA, as others have mentioned.

However, the SHOW command is pretty flexible, E.g.:

SHOW tables like '%s%'

Here's an overview from MS:

Consuming Web Services in Excel 2007

Sub FnGetSheetsName()

    Dim mainworkBook As Workbook

    Set mainworkBook = ActiveWorkbook

    For i = 1 To mainworkBook.Sheets.Count

    'Either we can put all names in an array , here we are printing all the names in Sheet 2

    mainworkBook.Sheets("Sheet2").Range("A" & i) = mainworkBook.Sheets(i).Name

    Next i

End Sub

Hurrah! Adding commons-collections jar files to my project resolved this problem. Two thumbs up to Lucky Sharma.

Solution: Add commons-collections4-4.1.jar file in your build path and try it again. It will work.

You can download it from https://mvnrepository.com/artifact/org.apache.commons/commons-collections4/4.1

the answer is

Dictionary

take look at my function, its simple add uses most important member functions inside Dictionary

this function return false if the list contain Duplicates items

 public static bool HasDuplicates<T>(IList<T> items)
    {
        Dictionary<T, bool> mp = new Dictionary<T, bool>();
        for (int i = 0; i < items.Count; i++)
        {
            if (mp.ContainsKey(items[i]))
            {
                return true; // has duplicates
            }
            mp.Add(items[i], true);
        }
        return false; // no duplicates
    }

Error is that you are using 'ID' in lower case like 'checkbox1' but when you loop json object its return in upper case. So you need to replace checkbox1 to CHECKBOX1.

In my case :-

var response = jQuery.parseJSON(response);

$.each(response, function(key, value) {
   $.each(value, function(key, value){
        $('#'+key).val(value);
   });
});

Before

  <input type="text" name="abc" id="abc" value="">

I am getting the same error but when i replace the id in html code its work fine.

After

<input type="text" name="abc" id="ABC" value="">

SET session_replication_role = replica; 

It doesn't work with PostgreSQL 9.4 on my Linux machine if i change a table through table editor in pgAdmin and works if i change table through ordinary query. Manual changes in pg_trigger table also don't work without server restart but dynamic query like on postgresql.nabble.com ENABLE / DISABLE ALL TRIGGERS IN DATABASE works. It could be useful when you need some tuning.

For example if you have tables in a particular namespace it could be:

create or replace function disable_triggers(a boolean, nsp character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_namespace n
        join pg_class c on c.relnamespace = n.oid and c.relhastriggers = true
        where n.nspname = nsp
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

If you want to disable all triggers with certain trigger function it could be:

create or replace function disable_trigger_func(a boolean, f character varying) returns void as
$$
declare 
act character varying;
r record;
begin
    if(a is true) then
        act = 'disable';
    else
        act = 'enable';
    end if;

    for r in select c.relname from pg_proc p 
        join pg_trigger t on t.tgfoid = p.oid
        join pg_class c on c.oid = t.tgrelid
        where p.proname = f
    loop
        execute format('alter table %I %s trigger all', r.relname, act); 
    end loop;
end;
$$
language plpgsql;

PostgreSQL documentation for system catalogs

There are another control options of trigger firing process:

ALTER TABLE ... ENABLE REPLICA TRIGGER ... - trigger will fire in replica mode only.

ALTER TABLE ... ENABLE ALWAYS TRIGGER ... - trigger will fire always (obviously)

Number((6.688689).toFixed(1)); // 6.7

var number = 6.688689;
var roundedNumber = Math.round(number * 10) / 10;

Use toFixed() function.

(6.688689).toFixed(); // equal to "7"
(6.688689).toFixed(1); // equal to "6.7"
(6.688689).toFixed(2); // equal to "6.69"

If by application id, you're referring to package name, you can use the method Context::getPackageName (http://http://developer.android.com/reference/android/content/Context.html#getPackageName%28%29).

In case you wish to communicate with other application, there are multiple ways:

1. Start an activity of another application and send data in the "Extras" of the "Intent"
2. Send a broadcast with specific action/category and send data in the extras
3. If you just need to share structured data, use content provider
4. If the other application needs to continuously run in the background, use Server and "bind" yourself to the service.

If you can elaborate your exact requirement, the community will be able to help you better.

A good rule of thumb is ".h files should have declarations [potentially] used by multiple source files, but no code that gets run."

@shash answered this elsewhere

A Pythonic way to find the index of the maximum list element would be

position = max(enumerate(a), key=lambda x: x[1])[0]

Which does one pass. Yet, it is slower than the solution by @Silent_Ghost and, even more so, @nmichaels:

for i in s m j n; do echo $i;  python -mtimeit -s"import maxelements as me" "me.maxelements_${i}(me.a)"; done
s
100000 loops, best of 3: 3.13 usec per loop
m
100000 loops, best of 3: 4.99 usec per loop
j
100000 loops, best of 3: 3.71 usec per loop
n
1000000 loops, best of 3: 1.31 usec per loop

You could also write your own Control for this, in case you want to use this more often. Assuming you have multiple TextBoxes in a Grid, it would look something like this:

public class AdvanceOnEnterTextBox : UserControl
{

    TextBox _TextBox;
    public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(String), typeof(AdvanceOnEnterTextBox), null);
    public static readonly DependencyProperty InputScopeProperty = DependencyProperty.Register("InputScope", typeof(InputScope), typeof(AdvanceOnEnterTextBox), null);


    public AdvanceOnEnterTextBox()
    {
        _TextBox = new TextBox();
        _TextBox.KeyDown += customKeyDown;
        Content = _TextBox;

    }


    /// <summary>
    /// Text for the TextBox
    /// </summary>
    public String Text
    {
        get { return _TextBox.Text; }
        set { _TextBox.Text = value; }
    }


    /// <summary>
    /// Inputscope for the Custom Textbox
    /// </summary>
    public InputScope InputScope
    {
        get { return _TextBox.InputScope; }
        set { _TextBox.InputScope = value; }
    }


    void customKeyDown(object sender, KeyEventArgs e)
    {
        if (!e.Key.Equals(Key.Enter)) return;

        var element = ((TextBox)sender).Parent as AdvanceOnEnterTextBox;
        if (element != null)
        {
            int currentElementPosition = ((Grid)element.Parent).Children.IndexOf(element);
            try
            {
                // Jump to the next AdvanceOnEnterTextBox (assuming, that Labels are inbetween).
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition + 2)).Focus();
            }
            catch (Exception)
            {
                // Close Keypad if this was the last AdvanceOnEnterTextBox
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = false;
                ((AdvanceOnEnterTextBox)((Grid)element.Parent).Children.ElementAt(currentElementPosition)).IsEnabled = true;
            }
        }
    }
}

I've got a YouTube video on this.

Short answer: Use mock when you're passing in the thing that you want mocked, and patch if you're not. Of the two, mock is strongly preferred because it means you're writing code with proper dependency injection.

Silly example:

# Use a mock to test this.
my_custom_tweeter(twitter_api, sentence):
    sentence.replace('cks','x')   # We're cool and hip.
    twitter_api.send(sentence)

# Use a patch to mock out twitter_api. You have to patch the Twitter() module/class 
# and have it return a mock. Much uglier, but sometimes necessary.
my_badly_written_tweeter(sentence):
    twitter_api = Twitter(user="XXX", password="YYY")
    sentence.replace('cks','x') 
    twitter_api.send(sentence)

Just remove activation section, I don't know why -Pdev1 doesn't override default false activation. But if you omit this:

<activation> <activeByDefault>false</activeByDefault> </activation>

then your profile will be activated only after explicit declaration as -Pdev1

In your aspx :

<form id="form1" runat="server" enctype="multipart/form-data">
 <input type="file" id="myFile" name="myFile" />
 <asp:Button runat="server" ID="btnUpload" OnClick="btnUploadClick" Text="Upload" />
</form>

In code behind :

protected void btnUploadClick(object sender, EventArgs e)
{
    HttpPostedFile file = Request.Files["myFile"];

    //check file was submitted
    if (file != null && file.ContentLength > 0)
    {
        string fname = Path.GetFileName(file.FileName);
        file.SaveAs(Server.MapPath(Path.Combine("~/App_Data/", fname)));
    }
}

Disclaimer: I am involved in the rest2mobile open source project

Another alternative as a REST client is to use rest2mobile.

The approach is slightly different as it uses concrete rest examples to generate the client code for the REST service. The code replaces the REST URL and JSON payloads with native java methods and POJOs. It also automatically handles server connections, asynchronous invocations and POJO to/from JSON conversions.

Note that this tool comes in different flavors (cli, plugins, android/ios/js support) and you can use the android studio plugin to generate the API directly into your app.

All the code can be found on github here.

I'd had this issue with Eclipse 2019-12 where the includes were previously being resolved, but then weren't. This was with a Meson build C/C++ project. I'm not sure exactly what happened, but closing the project and reopening it resolved the issue for me.

Curly braces are always needed for accessing array elements and carrying out brace expansion.

It's good to be not over-cautious and use {} for shell variable expansion even when there is no scope for ambiguity.

For example:

dir=log
prog=foo
path=/var/${dir}/${prog}      # excessive use of {}, not needed since / can't be a part of a shell variable name
logfile=${path}/${prog}.log   # same as above, . can't be a part of a shell variable name
path_copy=${path}             # {} is totally unnecessary
archive=${logfile}_arch       # {} is needed since _ can be a part of shell variable name

So, it is better to write the three lines as:

path=/var/$dir/$prog
logfile=$path/$prog.log
path_copy=$path

which is definitely more readable.

Since a variable name can't start with a digit, shell doesn't need {} around numbered variables (like $1, $2 etc.) unless such expansion is followed by a digit. That's too subtle and it does make to explicitly use {} in such contexts:

set app      # set $1 to app
fruit=$1le   # sets fruit to apple, but confusing
fruit=${1}le # sets fruit to apple, makes the intention clear

I've found this answer over here on stackoverflow which works perfectly for me:

use this in style

body {
    overflow-x: hidden;
    width: 100%;
}

Use this in head tag

<meta name="viewport" content="user-scalable=no, width=device-width, initial-scale=1.0" />
<meta name="apple-mobile-web-app-capable" content="yes" />

A slight addition of mine in case your body has padding (to prevent the device from scaling to the body content-box, and thus still adding a horizontal scrollbar):

body {
    overflow-x: hidden;
    width: 100%;
    -webkit-box-sizing: border-box;
       -moz-box-sizing: border-box;
            box-sizing: border-box;
}

You may not want to disable all ssl Verificatication and so you can just disable the hostName verification via this which is a bit less scary than the alternative:

HttpsURLConnection.setDefaultHostnameVerifier(
    SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

[EDIT]

As mentioned by conapart3 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER is now deprecated, so it may be removed in a later version, so you may be forced in the future to roll your own, although I would still say I would steer away from any solutions where all verification is turned off.

Thanks,Bruno for giving me heads up on Common Name and Subject Alternative Name. As we figured out certificate was generated with CN with DNS name of network and asked for regeneration of new certificate with Subject Alternative Name entry i.e. san=ip:10.0.0.1. which is the actual solution.

But, we managed to find out a workaround with which we can able to run on development phase. Just add a static block in the class from which we are making ssl connection.

static {
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier()
        {
            public boolean verify(String hostname, SSLSession session)
            {
                // ip address of the service URL(like.23.28.244.244)
                if (hostname.equals("23.28.244.244"))
                    return true;
                return false;
            }
        });
}

If you happen to be using Java 8, there is a much slicker way of achieving the same result:

static {
    HttpsURLConnection.setDefaultHostnameVerifier((hostname, session) -> hostname.equals("127.0.0.1"));
}

In my case, I wanted to center in a parent container with position: absolute.

<div class="absolute-container">
    <div class="parent-container">
        <div class="centered-content">
            My content
        </div>
    </div>
</div>

I had to add some positioning for top, bottom, left & right.

.absolute-container {
    position:absolute;
    top:0;
    left:0;
    bottom:0;
    right:0;
}

.parent-container {
    margin: 0;
    padding: 0;
    width: 100%;
    height: 100%;
    display: table
}

.centered-content {
    display: table-cell;
    text-align: center;
    vertical-align: middle
}

One more solution able to control the how many decimal digits to print out based on needs (if you don't want to print redundant zero(s))

For example, if you have a vector as elements and would like to get sum of it

elements <- c(-1e-05, -2e-04, -3e-03, -4e-02, -5e-01, -6e+00, -7e+01, -8e+02)
sum(elements)
## -876.5432

Apparently, the last digital as 1 been truncated, the ideal result should be -876.54321, but if set as fixed printing decimal option, e.g sprintf("%.10f", sum(elements)), redundant zero(s) generate as -876.5432100000

Following the tutorial here: printing decimal numbers, if able to identify how many decimal digits in the certain numeric number, like here in -876.54321, there are 5 decimal digits need to print, then we can set up a parameter for format function as below:

decimal_length <- 5
formatC(sum(elements), format = "f", digits = decimal_length)
## -876.54321

We can change the decimal_length based on each time query, so it can satisfy different decimal printing requirement.

Just in case you forgot or avoided to copy through PHPMYADMIN export feature..

Procedure: You can manually copy: Procedure For MAC OS, for latest versions of XAMPP

Location : Find the database folders here /Users/XXXXUSER/XAMPP/xamppfiles/var/mysql..

Solution: Copy the entire folder with database names into your new xampp in similar folder.

Hope it helps, happy coding.

jQuery.fn.sort = function() {  
    return this.pushStack( [].sort.apply( this, arguments ), []);  
};  

 function sortLastName(a,b){  
     if (a.l_name == b.l_name){
       return 0;
     }
     return a.l_name> b.l_name ? 1 : -1;  
 };  
  function sortLastNameDesc(a,b){  
     return sortLastName(a,b) * -1;  
 };
var people= [
{
"f_name": "john",
"l_name": "doe",
"sequence": "0",
"title" : "president",
"url" : "google.com",
"color" : "333333",
},
{
"f_name": "michael",
"l_name": "goodyear",
"sequence": "0",
"title" : "general manager",
"url" : "google.com",
"color" : "333333",
}]

sorted=$(people).sort(sortLastNameDesc);  

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

Short answer, yes, sort of. You can use Objective-C++, which you can read about at Apple Developer Connection.

If you know C++ already, learning Objective-C would be pretty simple, if you decided to give that a try. More info on that topic is at the ADC as well.

This simulates a character array but you can substitute SUBSTR for ELT to simulate a string array

declare t_tipos varchar(255) default 'ABCDE';
declare t_actual char(1);
declare t_indice integer default 1;
while t_indice<length(t_tipos)+1 do
    set t_actual=SUBSTR(t_tipos,t_indice,1);
        select t_actual;
        set t_indice=t_indice+1;
end while;

For PHP 5.3 this should work. You may need to fiddle with passing $dateInfo['is_dst'], wasn't working for me anyhow.

$date = '05/Feb/2010:14:00:01';
$dateInfo = date_parse_from_format('d/M/Y:H:i:s', $date);
$unixTimestamp = mktime(
    $dateInfo['hour'], $dateInfo['minute'], $dateInfo['second'],
    $dateInfo['month'], $dateInfo['day'], $dateInfo['year'],
    $dateInfo['is_dst']
);

Versions prior, this should work.

$date = '05/Feb/2010:14:00:01';
$format = '@^(?P<day>\d{2})/(?P<month>[A-Z][a-z]{2})/(?P<year>\d{4}):(?P<hour>\d{2}):(?P<minute>\d{2}):(?P<second>\d{2})$@';
preg_match($format, $date, $dateInfo);
$unixTimestamp = mktime(
    $dateInfo['hour'], $dateInfo['minute'], $dateInfo['second'],
    date('n', strtotime($dateInfo['month'])), $dateInfo['day'], $dateInfo['year'],
    date('I')
);

You may not like regular expressions. You could annotate it, of course, but not everyone likes that either. So, this is an alternative.

$day = $date[0].$date[1];
$month = date('n', strtotime($date[3].$date[4].$date[5]));
$year = $date[7].$date[8].$date[9].$date[10];
$hour = $date[12].$date[13];
$minute = $date[15].$date[16];
$second = $date[18].$date[19];

Or substr, or explode, whatever you wish to parse that string.

There is no separate 64-bit version of Chromedriver. The version available at https://sites.google.com/a/chromium.org/chromedriver/downloads works on both 32 and 64-bit Windows, against either 32-or 64-bit Chrome.

This was confirmed in the Chromedriver issue tracker: https://bugs.chromium.org/p/chromedriver/issues/detail?id=1797#c1

Yes, Chromedriver works on 64-bit Windows and against 64-bit Chrome successfully.

I came here while searching for the answer to if it works on 64-bit Chrome following the announcement that from version 58 Chrome will default to 64-bit on Windows provided certain conditions are met:
https://chromereleases.googleblog.com/2017/05/stable-channel-update-for-desktop.html

In order to improve stability, performance, and security, users who are currently on 32-bit version of Chrome, and 64-bit Windows with 4GB or more of memory and auto-update enabled will be automatically migrated to 64-bit Chrome during this update. 32-bit Chrome will still be available via the Chrome download page.

HTML

<div id="mydiv" data-myval="10"></div>

JS

var a = $('#mydiv').data('myval'); //getter

$('#mydiv').data('myval',20); //setter

Demo

Reference

From the reference:

jQuery itself uses the .data() method to save information under the names 'events' and 'handle', and also reserves any data name starting with an underscore ('_') for internal use.

It should be noted that jQuery's data() doesn't change the data attribute in HTML.

So, if you need to change the data attribute in HTML, you should use .attr() instead.

HTML

<div id="outer">
    <div id="mydiv" data-myval="10"></div>
</div>

?JS:

alert($('#outer').html());   // alerts <div id="mydiv" data-myval="10"> </div>
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').attr("data-myval","20"); //setter
alert($('#outer').html());   //alerts <div id="mydiv" data-myval="20"> </div>

See this demo

You need to use the 'g' switch for a global search

var result = mystring.match(/(&|&)?([^=]+)=([^&]+)/g)

You can use Object.values([]), you might need this polyfill if you don't already:

const objectToValuesPolyfill = (object) => {
  return Object.keys(object).map(key => object[key]);
};
Object.values = Object.values || objectToValuesPolyfill;

https://stackoverflow.com/a/54822153/846348

Then you can just do:

var object = {1: 'hello', 2: 'world'};
var array = Object.values(object);

Just remember that arrays in js can only use numerical keys so if you used something else in the object then those will become `0,1,2...x``

It can be useful to remove duplicates for example if you have a unique key.

var obj = {};
object[uniqueKey] = '...';

It seems to me, that it is by design that this file is empty.

A similar question has been asked here: https://stackoverflow.com/questions/2567432/ubuntu-apache-httpd-conf-or-apache2-conf

So, you should have a look for /etc/apache2/apache2.conf

Converting a Java Keystore into PEM Format

The most precise answer of all must be that this is NOT possible.

A Java keystore is merely a storage facility for cryptographic keys and certificates while PEM is a file format for X.509 certificates only.

function stripTrailingSlash(str) {
    if(str.substr(-1) === '/') {
        return str.substr(0, str.length - 1);
    }
    return str;
}

Note: IE8 and older do not support negative substr offsets. Use str.length - 1 instead if you need to support those ancient browsers.

I have set up a select with a custom arrow similar to Julio's answer, however it doesn't have a set width and uses an svg as a background image. (arrow_drop_down from material-ui icons)

select {
  -webkit-appearance: none;

If you need it to also work in IE update the svg arrow to base64 and add the following:

select::-ms-expand { display: none; }

background-image: url(data:image/svg+xml;base64,PHN2ZyBmaWxsPSdibGFjaycgaGVpZ2h0PScyNCcgdmlld0JveD0nMCAwIDI0IDI0JyB3aWR0aD0nMjQnIHhtbG5zPSdodHRwOi8vd3d3LnczLm9yZy8yMDAwL3N2Zyc+PHBhdGggZD0nTTcgMTBsNSA1IDUtNXonLz48cGF0aCBkPSdNMCAwaDI0djI0SDB6JyBmaWxsPSdub25lJy8+PC9zdmc+);

To make it easier to size and space the arrow, use this svg:

url("data:image/svg+xml,<svg width='24' height='24' xmlns='http://www.w3.org/2000/svg'><path d='m0,6l12,12l12,-12l-24,0z'/><path fill='none' d='m0,0l24,0l0,24l-24,0l0,-24z'/></svg>");

It doesn't have any spacing on the arrow's sides.

Author Note

This answer is out of date. Fig not longer exists and has been replaced by Docker compose. Accepted answers cannot be deleted ....

Docker Compose supports the building of project hierachy. So it's now easy to support a Dockerfile in each sub directory.

+-- docker-compose.yml
+-- project1
¦   +-- Dockerfile
+-- project2
    +-- Dockerfile

Original answer

I just create a directory containing a Dockerfile for each component. Example:

• Setting up a docker / fig Mesos environment

When building the containers just give the directory name and Docker will select the correct Dockerfile.

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

Try saving the file as Excel Workbook ONLY. NOT any other format. It worked for me. I was getting the same error.

There's an article over on MSDN that has a sample application for zipping and unzipping files and folders purely in C#. I've been using some of the classes in that successfully for a long time. The code is released under the Microsoft Permissive License, if you need to know that sort of thing.

EDIT: Thanks to Cheeso for pointing out that I'm a bit behind the times. The MSDN example I pointed to is in fact using DotNetZip and is really very fully-featured these days. Based on my experience of a previous version of this I'd happily recommend it.

SharpZipLib is also quite a mature library and is highly rated by people, and is available under the GPL license. It really depends on your zipping needs and how you view the license terms for each of them.

Here is example given which so how to use open and "python close

from sys import argv
script,filename=argv
txt=open(filename)
print "filename %r" %(filename)
print txt.read()
txt.close()
print "Change the file name"
file_again=raw_input('>')
print "New file name %r" %(file_again)
txt_again=open(file_again)
print txt_again.read()
txt_again.close()

It's necessary to how many times you opened file have to close that times.

This may be a little late; but someone will find it useful.

There's a Nuget Package for integrating AdminLTE - a popular Bootstrap template - to MVC5

Simply run this command in your Visual Studio Package Manager console

Install-Package AdminLteMvc

NB: It may take a while to install because it downloads all necessary files as well as create sample full and partial views (.cshtml files) that can guide you as you develop. A sample layout file _AdminLteLayout.cshtml is also provided.

You'll find the files in ~/Views/Shared/ folder

Try something like this:

SELECT * FROM clients WHERE CONCAT(field1, '', field2, '', fieldn) LIKE "%Mary%"

You may want to see SQL docs for additional information on string operators and regular expressions.

Edit: There may be some issues with NULL fields, so just in case you may want to use IFNULL(field_i, '') instead of just field_i

Case sensitivity: You can use case insensitive collation or something like this:

... WHERE LOWER(CONCAT(...)) LIKE LOWER("%Mary%")

Just search all field: I believe there is no way to make an SQL-query that will search through all field without explicitly declaring field to search in. The reason is there is a theory of relational databases and strict rules for manipulating relational data (something like relational algebra or codd algebra; these are what SQL is from), and theory doesn't allow things such as "just search all fields". Of course actual behaviour depends on vendor's concrete realisation. But in common case it is not possible. To make sure, check SELECT operator syntax (WHERE section, to be precise).

Place the image (cancel icon) with position absolute, adjust top and left properties and call method onclick event which clears the input field.

<div class="form-control">
    <input type="text" id="inputField" />
</div>
<span id="iconSpan"><img src="icon.png" onclick="clearInputField()"/></span>

In css position the span accordingly,

#iconSpan {
 position : absolute;
 top:1%;
 left :14%;
}

As user2357112 mentioned in the comments, you cannot use chained comparisons here. For elementwise comparison you need to use &. That also requires using parentheses so that & wouldn't take precedence.

It would go something like this:

mask = ((50  < df['heart rate']) & (101 > df['heart rate']) & (140 < df['systolic...

In order to avoid that, you can build series for lower and upper limits:

low_limit = pd.Series([90, 50, 95, 11, 140, 35], index=df.columns)
high_limit = pd.Series([160, 101, 100, 19, 160, 39], index=df.columns)

Now you can slice it as follows:

mask = ((df < high_limit) & (df > low_limit)).all(axis=1)
df[mask]

When you get a connection to PostgreSQL it is always to a particular database. To access a different database, you must get a new connection.

Using \c in psql closes the old connection and acquires a new one, using the specified database and/or credentials. You get a whole new back-end process and everything.

Press Ctrl+C

When you start the server it mentions this in the startup text.

The accepted answer will return all the parent nodes too. To get only the actual nodes with ABC even if the string is after
:

//*[text()[contains(.,'ABC')]]/text()[contains(.,"ABC")]

You could also use:

<body onload="focusOnInput()">
    <form name="passwordForm" action="verify.php" method="post">
        <input name="passwordInput" type="password" />
    </form>
</body>

And then in your JavaScript:

function focusOnInput() {
    document.forms["passwordForm"]["passwordInput"].focus();
}

It depends on the way your page behaves. If you want this to happens asynchronously, you have to use AJAX. Try out "jQuery post()" on Google to find some tuts.

In other case, if this will happen when a user submits a form, you can send the variable in an hidden field or append ?variableName=someValue" to then end of the URL you are opening. :

http://www.somesite.com/send.php?variableName=someValue

or

http://www.somesite.com/send.php?variableName=someValue&anotherVariable=anotherValue

This way, from PHP you can access this value as:

$phpVariableName = $_POST["variableName"];

for forms using POST method or:

$phpVariableName = $_GET["variableName"];

for forms using GET method or the append to url method I've mentioned above (querystring).

I was having the same problem, but using Long type. I changed for INT and it worked for me.

CREATE TABLE lists (
 id INT NOT NULL AUTO_INCREMENT,
 desc varchar(30),
 owner varchar(20),
 visibility boolean,
 PRIMARY KEY (id)
 );

To do this, you can use Microsoft's more advanced command-line shell called "Windows PowerShell." It should come standard on the latest versions of Windows, but you can download it from Microsoft if you don't already have it installed.

To get the last five lines in the text file simply read the file using Get-Content, then have Select-Object pick out the last five items/lines for you:

Get-Content c:\scripts\test.txt | Select-Object -last 5

I did some research and found out that byte.Parse is even slower than Convert.ToByte. The fastest conversion I could come up with uses approximately 15 ticks per byte.

    public static byte[] StringToByteArrayFastest(string hex) {
        if (hex.Length % 2 == 1)
            throw new Exception("The binary key cannot have an odd number of digits");

        byte[] arr = new byte[hex.Length >> 1];

        for (int i = 0; i < hex.Length >> 1; ++i)
        {
            arr[i] = (byte)((GetHexVal(hex[i << 1]) << 4) + (GetHexVal(hex[(i << 1) + 1])));
        }

        return arr;
    }

    public static int GetHexVal(char hex) {
        int val = (int)hex;
        //For uppercase A-F letters:
        //return val - (val < 58 ? 48 : 55);
        //For lowercase a-f letters:
        //return val - (val < 58 ? 48 : 87);
        //Or the two combined, but a bit slower:
        return val - (val < 58 ? 48 : (val < 97 ? 55 : 87));
    }

// also works on .NET Micro Framework where (in SDK4.3) byte.Parse(string) only permits integer formats.

No, there isn't. But you shouldn't rely on this if this is related to a security question.

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

This code is to find the whole current week. It is written in Swift 2.0 :

var i = 2
var weekday: [String] = []
var weekdate: [String] = []
var weekmonth: [String] = []

@IBAction func buttonaction(sender: AnyObject) {

    let currentDate = NSDate()
    let dateFormatter = NSDateFormatter()
    dateFormatter.dateFormat = "MMM-dd-yyyy"
    let dayOfWeekStrings = dateFormatter.stringFromDate(currentDate)
    let weekdays = getDayOfWeek(dayOfWeekStrings)
    let calendar = NSCalendar.currentCalendar()

    while((weekdays - weekdays) + i < 9)
    {
        let weekFirstDate = calendar.dateByAddingUnit(.Day, value: (-weekdays+i), toDate: NSDate(), options: [])

        let dayFormatter = NSDateFormatter()
        dayFormatter.dateFormat = "EEEE"
        let dayOfWeekString = dayFormatter.stringFromDate(weekFirstDate!)
        weekday.append(dayOfWeekString)

        let dateFormatter = NSDateFormatter()
        dateFormatter.dateFormat = "dd"
        let dateOfWeekString = dateFormatter.stringFromDate(weekFirstDate!)
        weekdate.append(dateOfWeekString)

        let monthFormatter = NSDateFormatter()
        monthFormatter.dateFormat = "MMMM"
        let monthOfWeekString = monthFormatter.stringFromDate(weekFirstDate!)
        weekmonth.append(monthOfWeekString)

        i++
    }

    for(var j = 0; j<7 ; j++)
    {
    let day = weekday[j]
    let date = weekdate[j]
    let month = weekmonth[j]
    var wholeweek = date + "-" + month + "(" + day + ")"
    print(wholeweek)
    }

}

func getDayOfWeek(today:String)->Int {
    let formatter  = NSDateFormatter()
    formatter.dateFormat = "MMM-dd-yyyy"
    let todayDate = formatter.dateFromString(today)!
    let myCalendar = NSCalendar(calendarIdentifier: NSCalendarIdentifierGregorian)!
    let myComponents = myCalendar.components(.Weekday, fromDate: todayDate)
    let daynumber = myComponents.weekday
    return daynumber
}

The output will be like this:

AFAIK JSON.Net does not provide functionality for reading from a URL. So you need to do this in two steps:

using (var webClient = new System.Net.WebClient()) {
    var json = webClient.DownloadString(URL);
    // Now parse with JSON.Net
}

I've taken Anas Nakawa's idea and improved it. First of all, there is no reason to actually run the function being declared. We want to know whether it parses correctly, not whether the code works. Second, a literal object is a better context for our purpose than var XXX as it's harder to break out of.

    function isValidVarName( name ) {
    try {
        return name.indexOf('}') === -1 && eval('(function() { a = {' + name + ':1}; a.' + name + '; var ' + name + '; }); true');
    } catch( e ) {
        return false;
    }
    return true;
}

// so we can see the test code
var _eval = eval;
window.eval = function(s) {
    console.log(s);
    return _eval(s);
}

console.log(isValidVarName('name'));
console.log(isValidVarName('$name'));
console.log(isValidVarName('not a name'));
console.log(isValidVarName('a:2,b'));
console.log(isValidVarName('"a string"'));

console.log(isValidVarName('xss = alert("I\'m in your vars executin mah scrip\'s");;;;;'));
console.log(isValidVarName('_;;;'));
console.log(isValidVarName('_=location="#!?"'));

console.log(isValidVarName('?'));
console.log(isValidVarName('HELLO'));
console.log(isValidVarName('????'));
console.log(isValidVarName('?????????????'));
console.log(isValidVarName('KingGeorge?'));
console.log(isValidVarName('}; }); alert("I\'m in your vars executin\' mah scripts"); true; // yeah, super valid'));
console.log(isValidVarName('if'));

var datestr = '2012.08.10';
var timestamp = (new Date(datestr.split(".").join("-")).getTime())/1000;

This post is right from SAP on Sep 20, 2012.

In short, they are still working on a release of Crystal Reports that will support VS2012 (including support for Windows 8) It will come in the form of a service pack release that updates the version currently supporting VS2010. At that time they will drop 2010/2012 from the name and simply call it Crystal Reports Developer.

If you want to download that version you can find it here.

Further, service packs etc. when released can be found here.

I would also add that I am currently using Visual Studio 2012. As long as you don't edit existing reports they continue to compile and work fine. Even on Windows 8. When I need to modify a report I can still open the project with VS2010, do my work, save my changes, and then switch back to 2012. It's a little bit of a pain but the ability for VS2010 and VS2012 to co-exist is nice in this regard. I'm also using TFS2012 and so far it hasn't had a problem with me modifying files in 2010 on a "2012" solution.

The oddly named "blame" command does this. If you use Tortoise, it gives you a "from revision" dialog, then a file listing with a line by line indicator of Revision number and author next to it.

If you right click on the revision info, you can bring up a "Show log" dialog that gives full checkin information, along with other files that were part of the checkin.

Apart from specifying an anchor in a page where you want to jump to, # is also used in jQuery hash or fragment navigation.

Here is a plunker showing how you can use it with the ngClass directive.

I'm demonstrating with divs instead of imgs though.

Template:

<ul>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 1}" (click)="setSelected(1)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 2}" (click)="setSelected(2)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 3}" (click)="setSelected(3)"> </div></li>
</ul>

TS:

export class App {
  selectedIndex = -1;

  setSelected(id: number) {
    this.selectedIndex = id;
  }
}

Here's the Query Analyzer template for an in-line function - it returns 2 values by default:

-- =============================================  
-- Create inline function (IF)  
-- =============================================  
IF EXISTS (SELECT *   
   FROM   sysobjects   
   WHERE  name = N'<inline_function_name, sysname, test_function>')  
DROP FUNCTION <inline_function_name, sysname, test_function>  
GO  

CREATE FUNCTION <inline_function_name, sysname, test_function>   
(<@param1, sysname, @p1> <data_type_for_param1, , int>,   
 <@param2, sysname, @p2> <data_type_for_param2, , char>)  
RETURNS TABLE   
AS  
RETURN SELECT   @p1 AS c1,   
        @p2 AS c2  
GO  

-- =============================================  
-- Example to execute function  
-- =============================================  
SELECT *   
FROM <owner, , dbo>.<inline_function_name, sysname, test_function>   
    (<value_for_@param1, , 1>,   
     <value_for_@param2, , 'a'>)  
GO  

Try this code

UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:<your ViewController object>];

[self.view.window.rootViewController presentViewController:navigationController animated:YES completion:nil];

I am the original poster and I accepted the above answer by DGH without having first used it in the code.

Once I did use I realised that it needed a little tweaking to actually do what I needed it to do (to be fair to DGH he/she did say "or something similar" !).

I thought it was worth posting the tweak here for the benefit of others:

    try:
        a = Application("abcdef", "")
    except pySourceAidExceptions.PathIsNotAValidOne:
        pass
    except:
        self.assertTrue(False)

What I was attempting to do here was to ensure that if an attempt was made to instantiate an Application object with a second argument of spaces the pySourceAidExceptions.PathIsNotAValidOne would be raised.

I believe that using the above code (based heavily on DGH's answer) will do that.

Use a FULL OUTER JOIN:

select 
   a.col_a,
   a.col_b,
   b.col_c
from
   (select col_a,col_bfrom tab1) a
join 
   (select col_a,col_cfrom tab2) b 
on a.col_a= b.col_a

SizedBox(
    width: 200.0,
    child: Text('PRODUCERS CAVITY FIGHTER 50X140g',
                overflow: TextOverflow.ellipsis,
                style: Theme.of(context).textTheme.body2))

Just wrap in inside a widget that can take a specific width for it to work or it will assume the width of the parent container.

     //controller  You can use this way

    public ActionResult Index()
    {
      List<Fund> fundList = db.Funds.ToList();
     ViewBag.Funds = fundList;
        return View();
    }




<--View ; You can use this way html-->

@foreach (var item in (List<Fund>)ViewBag.Funds)
{
    <p>@item.firtname</p>
}

During a merge Git wants to keep track of the parent branches for all sorts of reasons. What you want to do is not a merge as git sees it. You will likely want to do a rebase or cherry-pick manually.

Go to [Tools, Options], section "Web Forms Designer" and enable the option "Enable Web Forms Designer". That should give you the Design and Split option again.

In your destination field you want to use VLOOKUP like so:

=VLOOKUP(Sheet1!A1:A100,Sheet2!A1:F100,6,FALSE)

VLOOKUP Arguments:

1. The set fields you want to lookup.
2. The table range you want to lookup up your value against. The first column of your defined table should be the column you want compared against your lookup field. The table range should also contain the value you want to display (Column F).
3. This defines what field you want to display upon a match.
4. FALSE tells VLOOKUP to do an exact match.

Description

You can use another overload of the DropDownList method. Pick the one you need and pass in a object with your html attributes.

Sample

@Html.DropDownList("CategoryID", null, new { @onchange="location = this.value;" })

    </shape>

</rotate>

this is one simple approach using spring boot

TestClass.java

@Configuration
@Profile("one")
@PropertySource("file:/{selected location}/app.properties")
public class TestClass {

    @Autowired
    Environment env;

    @Bean
    public boolean test() {
        System.out.println(env.getProperty("test.one"));
        return true;
    }
}

the app.properties context, in your selected location

test.one = 1234

your spring boot application

@SpringBootApplication

public class TestApplication {

    public static void main(String[] args) {
        SpringApplication.run(testApplication.class, args);
    }
}

and the predefined application.properties context

spring.profiles.active = one

you can write as many configuration class as you like and enable/disable them just by setting spring.profiles.active = the profile name/names {separated by commas}

as you can see spring boot is great it just needs sometime to get familiar with, it's worth mentioning that you may use @Value on your fields as well

@Value("${test.one}")
String str;

Ajax (also AJAX) an acronym for Asynchronous JavaScript and XML) is a group of interrelated web development techniques used on the client-side to create asynchronous web applications. With Ajax, web applications can send data to, and retrieve data from, a server asynchronously Below is example code:

Jsp page java script function to submit data to servlet with two variable firstName and lastName:

function onChangeSubmitCallWebServiceAJAX()
    {
      createXmlHttpRequest();
      var firstName=document.getElementById("firstName").value;
      var lastName=document.getElementById("lastName").value;
      xmlHttp.open("GET","/AJAXServletCallSample/AjaxServlet?firstName="
      +firstName+"&lastName="+lastName,true)
      xmlHttp.onreadystatechange=handleStateChange;
      xmlHttp.send(null);

    }

Servlet to read data send back to jsp in xml format ( You could use text as well. Just you need to change response content to text and render data on javascript function.)

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

    String firstName = request.getParameter("firstName");
    String lastName = request.getParameter("lastName");

    response.setContentType("text/xml");
    response.setHeader("Cache-Control", "no-cache");
    response.getWriter().write("<details>");
    response.getWriter().write("<firstName>"+firstName+"</firstName>");
    response.getWriter().write("<lastName>"+lastName+"</lastName>");
    response.getWriter().write("</details>");
}

I reproduced this just now by accident:

1. lists the remote branches

   git branch -r
         origin/Feature/f1234
         origin/master
   

2. I want to checkout one locally, so I cut paste:

   git checkout origin/Feature/f1234
   

3. Presto! Detached HEAD state

   You are in 'detached HEAD' state. [...])
   

Solution #1:

Do not include origin/ at the front of my branch spec when checking it out:

git checkout Feature/f1234

Solution #2:

Add -b parameter which creates a local branch from the remote

git checkout -b origin/Feature/f1234 or

git checkout -b Feature/f1234 it will fall back to origin automatically

The most recent versions of hibernate JPA provider applies the bean validation constraints (JSR 303) like @NotNull to DDL by default (thanks to hibernate.validator.apply_to_ddl property defaults to true). But there is no guarantee that other JPA providers do or even have the ability to do that.

You should use bean validation annotations like @NotNull to ensure, that bean properties are set to a none-null value, when validating java beans in the JVM (this has nothing to do with database constraints, but in most situations should correspond to them).

You should additionally use the JPA annotation like @Column(nullable = false) to give the jpa provider hints to generate the right DDL for creating table columns with the database constraints you want. If you can or want to rely on a JPA provider like Hibernate, which applies the bean validation constraints to DDL by default, then you can omit them.

What you have should work but can be reduced to:

select * from table where concat_ws(' ',first_name,last_name) 
like '%$search_term%';

Can you provide an example name and search term where this doesn't work?

If you don't want to download an archive you can use GitHub Pages to render this.

1. Fork the repository to your account.
2. Clone it locally on your machine
3. Create a gh-pages branch (if one already exists, remove it and create a new one based off master).
4. Push the branch back to GitHub.
5. View the pages at http://username.github.io/repo`

In code:

git clone [email protected]:username/repo.git
cd repo
git branch gh-pages
# Might need to do this first: git branch -D gh-pages
git push -u origin gh-pages # Push the new branch back to github
Go to http://username.github.io/repo

HTML

<Select id="SDistrict" class="form-control">
    <option value="1" data-color="yellow" > Mango </option>
</select>

JS when initialized

   $('#SDistrict').selectize({
        create: false,
        sortField: 'text',
        onInitialize: function() {
            var s = this;
            this.revertSettings.$children.each(function() {
                $.extend(s.options[this.value], $(this).data());
            });
        },
        onChange: function(value) {
            var option = this.options[value];
            alert(option.text + ' color is ' + option.color);
        }
    });

You can access data attribute of option tag with option.[data-attribute]

I personally suggest to use the autoNumeric plugin from http://www.decorplanit.com/plugin/ - it supports all different variations like prefix/suffix handling, currency handling, negative value formatting, min, max etc.

To do POST you'll need to have a form.

<form action="employee.action" method="post">
    <input type="submit" value="Employee1" />
</form>

There are some ways to post data with hyperlinks, but you'll need some javascript, and a form.

Some tricks: Make a link use POST instead of GET and How do you post data with a link

Edit: to load response on a frame you can target your form to your frame:

<form action="employee.action" method="post" target="myFrame">

Before you can commit and push, you need to init a working repository tree for a submodule. I am using tortoise and do following things:

First check if there exist .git file (not a directory)

• if there is such file it contains path to supermodule git directory
• delete this file
• do git init
• do git add remote path the one used for submodule
• follow instructions below

If there was .git file, there surly was .git directory which tracks local tree. You still need to a branch (you can create one) or switch to master (which sometimes does not work). Best to do is - git fetch - git pull. Do not omit fetch.

Now your commits and pulls will be synchronized with your origin/master

Yes. Here's the way using pipe( | ) separator,

try
{
    .......
}    
catch
{
    catch(IllegalArgumentException | SecurityException | IllegalAccessException | NoSuchFieldException e)
}

The simplest way:

ping hostname

e.g.

ping dynlab938.meng.auth.gr

it will print: Pinging dynlab938.meng.auth.gr [155.207.29.38] with 32 bytes of data

npm update solves the issue for me

Sticky footer with fixed height:

HTML scheme:

<body>
   <div id="wrap">
   </div>
   <div id="footer">
   </div>
</body>

CSS:

html, body {
    height: 100%;
}
#wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -60px;
}
#footer {
    height: 60px;
}

I found this function on a blog

 ggplotRegression <- function (fit) {

    `require(ggplot2)

    ggplot(fit$model, aes_string(x = names(fit$model)[2], y = names(fit$model)[1])) + 
      geom_point() +
      stat_smooth(method = "lm", col = "red") +
      labs(title = paste("Adj R2 = ",signif(summary(fit)$adj.r.squared, 5),
                         "Intercept =",signif(fit$coef[[1]],5 ),
                         " Slope =",signif(fit$coef[[2]], 5),
                         " P =",signif(summary(fit)$coef[2,4], 5)))
    }`

once you loaded the function you could simply

ggplotRegression(fit)

you can also go for ggplotregression( y ~ x + z + Q, data)

Hope this helps.

You can pass values from one activity to another activity using the Bundle. In your current activity, create a bundle and set the bundle for the particular value and pass that bundle to the intent.

Intent intent = new Intent(this,NewActivity.class);
Bundle bundle = new Bundle();
bundle.putString(key,value);
intent.putExtras(bundle);
startActivity(intent);

Now in your NewActivity, you can get this bundle and retrive your value.

Bundle bundle = getArguments();
String value = bundle.getString(key);

You can also pass data through the intent. In your current activity, set intent like this,

Intent intent = new Intent(this,NewActivity.class);
intent.putExtra(key,value);
startActivity(intent);

Now in your NewActivity, you can get that value from intent like this,

String value = getIntent().getExtras().getString(key);

You can disable FK and CHECK constraints only in SQL 2005+. See ALTER TABLE

ALTER TABLE foo NOCHECK CONSTRAINT ALL

or

ALTER TABLE foo NOCHECK CONSTRAINT CK_foo_column

Primary keys and unique constraints can not be disabled, but this should be OK if I've understood you correctly.

this is work for me ,but you should merge remote repository files to the local files:

git init
git remote add origin url-to-git
git branch --set-upstream-to=origin/master master
git fetch
git status

Associative Arrays in JavaScript don't really work the same as they do in other languages. for each statements are complicated (because they enumerate inherited prototype properties). You could declare properties on an object/associative array as Pointy mentioned, but really for this sort of thing you should use an array with the push method:

jsArr = []; 

for (var i = 1; i <= 10; i++) { 
    jsArr.push('example ' + 1); 
} 

Just don't forget that indexed arrays are zero-based so the first element will be jsArr[0], not jsArr[1].

Below command works for me. Provided that all required jars including testng jar kept inside lib.

java -cp "lib/*" org.testng.TestNG testng.xml

GUI-driven approach: Open the docker desktop tool (that usually comes with Docker):

1. under "Containers / Apps" stop all running instances of that image
2. under "Images" remove the build image (hover over the box name to get a context menu), eventually also the underlying base image

1. The solutions presented so far suffer from a "reinventing the wheel" approach. Quoting @AMC:

If you're new to the library, consider double-checking whether the functionality you need is already offered by those Pandas objects.

2. If you convert a dataframe to a list of lists you will lose information - namely the index and columns names.

My solution: use to_dict()

dict_of_lists = df.to_dict(orient='split')

This will give you a dictionary with three lists: index, columns, data. If you decide you really don't need the columns and index names, you get the data with

dict_of_lists['data']

Well, first of all, you're wasting memory with the new HashMap creation call. Your second line completely disregards the reference to this created hashmap, making it then available to the garbage collector. So, don't do that, use:

private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");

Secondly, the compiler is complaining that you cast the object to a HashMap without checking if it is a HashMap. But, even if you were to do:

if(getApplicationContext().getBean("someMap") instanceof HashMap) {
    private Map<String, String> someMap = (HashMap<String, String>)getApplicationContext().getBean("someMap");
}

You would probably still get this warning. The problem is, getBean returns Object, so it is unknown what the type is. Converting it to HashMap directly would not cause the problem with the second case (and perhaps there would not be a warning in the first case, I'm not sure how pedantic the Java compiler is with warnings for Java 5). However, you are converting it to a HashMap<String, String>.

HashMaps are really maps that take an object as a key and have an object as a value, HashMap<Object, Object> if you will. Thus, there is no guarantee that when you get your bean that it can be represented as a HashMap<String, String> because you could have HashMap<Date, Calendar> because the non-generic representation that is returned can have any objects.

If the code compiles, and you can execute String value = map.get("thisString"); without any errors, don't worry about this warning. But if the map isn't completely of string keys to string values, you will get a ClassCastException at runtime, because the generics cannot block this from happening in this case.

You get into a difficult situation when it is necessary to understand how scopes, ngRepeat and ngModel with NgModelController work. Also try to use 1.0.3 version. Your example will work a little differently.

You can simply use solution provided by jm-

But if you want to deal with the situation more deeply, you have to understand:

• how AngularJS works;
• scopes have a hierarchical structure;
• ngRepeat creates new scope for every element;
• ngRepeat build cache of items with additional information (hashKey); on each watch call for every new item (that is not in the cache) ngRepeat constructs new scope, DOM element, etc. More detailed description.
• from 1.0.3 ngModelController rerenders inputs with actual model values.

How your example "Binding to each element directly" works for AngularJS 1.0.3:

• you enter letter 'f' into input;
• ngModelController changes model for item scope (names array is not changed) => name == 'Samf', names == ['Sam', 'Harry', 'Sally'];
• $digest loop is started;
• ngRepeat replaces model value from item scope ('Samf') by value from unchanged names array ('Sam');
• ngModelController rerenders input with actual model value ('Sam').

How your example "Indexing into the array" works:

• you enter letter 'f' into input;
• ngModelController changes item in names array => `names == ['Samf', 'Harry', 'Sally'];
• $digest loop is started;
• ngRepeat can't find 'Samf' in cache;
• ngRepeat creates new scope, adds new div element with new input (that is why the input field loses focus - old div with old input is replaced by new div with new input);
• new values for new DOM elements are rendered.

Also, you can try to use AngularJS Batarang and see how changes $id of the scope of div with input in which you enter.

If you don't want to install anything you can output html. Then open the html file - it should open in a browser window, then right click to print. In the print window, select "save as pdf" in the bottom right hand corner if you're on a Mac. Voila!

@hussachai and @Jeffrey Kemp answers are pretty good. But they have something in common is the url returned is of virtual-host-style, not in path style. For more info regarding to the s3 url style, can refer to AWS S3 URL Styles. In case of some people want to have path style s3 url generated. Here's the step. Basically everything will be the same as @hussachai and @Jeffrey Kemp answers, only with one line setting change as below:

AmazonS3Client s3Client = (AmazonS3Client) AmazonS3ClientBuilder.standard()
                    .withRegion("us-west-2")
                    .withCredentials(DefaultAWSCredentialsProviderChain.getInstance())
                    .withPathStyleAccessEnabled(true)
                    .build();

// Upload a file as a new object with ContentType and title specified.
PutObjectRequest request = new PutObjectRequest(bucketName, stringObjKeyName, fileToUpload);
s3Client.putObject(request);
URL s3Url = s3Client.getUrl(bucketName, stringObjKeyName);
logger.info("S3 url is " + s3Url.toExternalForm());

This will generate url like: https://s3.us-west-2.amazonaws.com/mybucket/myfilename

I'm no c++ guy, but you should be able to get the gist from this.

public static string Reverse(string s) {
    if (s == null || s.Length < 2) {
        return s;
    }

    int length = s.Length;
    int loop = (length >> 1) + 1;
    int j;
    char[] chars = new char[length];
    for (int i = 0; i < loop; i++) {
        j = length - i - 1;
        chars[i] = s[j];
        chars[j] = s[i];
    }
    return new string(chars);
}

You need to put the last() indexing on the nodelist result, rather than as part of the selection criteria. Try:

(//element[@name='D'])[last()]

try to SendKeys instead of picking the date

driver.FindElement(yourBy).SendKeys(yourDateTime.ToString("ddd, dd.MM.yyyy",CultureInfo.CreateSpecificCulture("en-US")));

If it does not work, try to send native 'tab'

element.SendKeys(OpenQA.Selenium.Keys.Tab);

On iOS 9:

Settings -> General -> Device Management -> Developer app / your Apple ID -> Add/remove trust there

A side from the very long complete accepted answer there is an important point to make about IndexOutOfRangeException compared with many other exception types, and that is:

Often there is complex program state that maybe difficult to have control over at a particular point in code e.g a DB connection goes down so data for an input cannot be retrieved etc... This kind of issue often results in an Exception of some kind that has to bubble up to a higher level because where it occurs has no way of dealing with it at that point.

IndexOutOfRangeException is generally different in that it in most cases it is pretty trivial to check for at the point where the exception is being raised. Generally this kind of exception get thrown by some code that could very easily deal with the issue at the place it is occurring - just by checking the actual length of the array. You don't want to 'fix' this by handling this exception higher up - but instead by ensuring its not thrown in the first instance - which in most cases is easy to do by checking the array length.

Another way of putting this is that other exceptions can arise due to genuine lack of control over input or program state BUT IndexOutOfRangeException more often than not is simply just pilot (programmer) error.

Yes, you can store the integer directly:

int num = 45;

If you must parse a string, atoi or strol is going to win the "shortest amount of code" contest.

If you want to set backgroundColor of button programmatically then this code will surly help you

Swift 3 and Swift 4

self.yourButton.backgroundColor = UIColor.red

Swift 2.3 or lower

self.yourButton.backgroundColor = UIColor.redColor()

Using RGB

self.yourButton.backgroundColor = UIColor(red: 102/255, green: 250/255, blue: 51/255, alpha: 0.5)

or you can use float values

button.backgroundColor = UIColor(red: 0.4, green: 1.0, blue: 0.2, alpha: 0.5)

From my HomeController I want to call this Method and convert Json response to List

No you don't. You really don't want to add the overhead of an HTTP call and (de)serialization when the code is within reach. It's even in the same assembly!

Your ApiController goes against (my preferred) convention anyway. Let it return a concrete type:

public IEnumerable<QDocumentRecord> GetAllRecords()
{
    listOfFiles = ...
    return listOfFiles;
}

If you don't want that and you're absolutely sure you need to return HttpResponseMessage, then still there's absolutely no need to bother with calling JsonConvert.SerializeObject() yourself:

return Request.CreateResponse<List<QDocumentRecord>>(HttpStatusCode.OK, listOfFiles);

Then again, you don't want business logic in a controller, so you extract that into a class that does the work for you:

public class FileListGetter
{
    public IEnumerable<QDocumentRecord> GetAllRecords()
    {
        listOfFiles = ...
        return listOfFiles;
    }
}

Either way, then you can call this class or the ApiController directly from your MVC controller:

public class HomeController : Controller
{
    public ActionResult Index()
    {
        var listOfFiles = new DocumentsController().GetAllRecords();
        // OR
        var listOfFiles = new FileListGetter().GetAllRecords();

        return View(listOfFiles);
    }
}

But if you really, really must do an HTTP request, you can use HttpWebRequest, WebClient, HttpClient or RestSharp, for all of which plenty of tutorials exist.

Also possible by looking for substring with index() function:

awk '(index($3, "snow") != 0) {print}' dummy_file

Shorter version:

awk 'index($3, "snow")' dummy_file

You can also do something like this...

<input @input="myHandler('foo', 'bar', ...arguments)">

Evan You himself recommended this technique in one post on Vue forum. In general some events may emit more than one argument. Also as documentation states internal variable $event is meant for passing original DOM event.

Simpler:

ScriptManager.RegisterStartupScript(this.Page, this.Page.GetType(), "DoPostBack", "__doPostBack(sender, e)", true);

Unit test: Verifying that particular component (i.e., class) created or modified functions as designed. This test can be manual or automated, but it does not move beyond the boundary of the component.

Integration test: Verifying that the interaction of particular components function as designed. Integration tests can be performed at the unit level or the system level. These tests can be manual or automated.

Regression test: Verifying that new defects are not introduced into existing code. These tests can be manual or automated.

Depending upon your SDLC (waterfall, RUP, agile, etc.) particular tests may be performed in 'phases' or may all be performed, more or less, at the same time. For example, unit testing may be limited to developers who then turn the code over to testers for integration and regression testing. However, another approach might have developers doing unit testing and some level of integration and regression testing (using a TDD approach along with continuous integration and automated unit and regression tests).

The tool set will depend largely on the codebase, but there are many open source tools for unit testing (JUnit). HP's (Mercury) QTP or Borland's Silk Test are both tools for automated integration and regression testing.

std::stoi from string could also be used.

    #include <string>

    using namespace std;

    int main (int argc, char** argv)
    {
         if (argc >= 2)
         {
             int val = stoi(argv[1]);
             // ...    
         }
         return 0;
    }

You may try this way. just use a function to get your object

def get_object(self, id):
    try:
        return Comment.objects.get(pk=id)
    except Comment.DoesNotExist:
        return False
