There are several methods that can be useful to achieve field-specific results. One can be through the source method. And another method that can also be useful to receive cleaner and more summarized answers according to our interests is filter_path:

Document Json:

"hits" : [
  {
    "_index" : "xxxxxx",
    "_type" : "_doc",
    "_id" : "xxxxxx",
    "_score" : xxxxxx,
    "_source" : {
      "year" : 2020,
      "created_at" : "2020-01-29",
      "url" : "www.github.com/mbarr0987",
      "name":"github"
    }
  }

Query:

GET bot1/_search?filter_path=hits.hits._source.url
{
  "query": {
    "bool": {
      "must": [
        {"term": {"name.keyword":"github" }}
       ]
    }
  }
}

Output:

{
  "hits" : {
    "hits" : [
      {
        "_source" : {
          "url" : "www.github.com/mbarr0987"
            }
          }
      ]
   }
}

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

I had same problem and solution was obj = ClassName.objects.filter()

Rumble supports JSON natively with JSONiq and runs on Spark, managing DataFrames internally so you don't need to -- even if the data isn't fully structured:

let $coords := "42.974049,-81.205203%7C42.974298,-81.195755"
let $request := json-doc("http://maps.googleapis.com/maps/api/elevation/json?locations="||$coords||"&sensor=false")
for $obj in $request.results[]
return {
  "latitude" : $obj.location.lat,
  "longitude" : $obj.location.lng,
  "elevation" : $obj.elevation
}

The results can be exported to CSV and then reopened in any other host language as a DataFrame.

Use a json array, in the format:

[
{"ID":"12345","Timestamp":"20140101", "Usefulness":"Yes",
  "Code":[{"event1":"A","result":"1"},…]},
{"ID":"1A35B","Timestamp":"20140102", "Usefulness":"No",
  "Code":[{"event1":"B","result":"1"},…]},
{"ID":"AA356","Timestamp":"20140103", "Usefulness":"No",
  "Code":[{"event1":"B","result":"0"},…]},
...
]

Then import it into your python code

import json

with open('file.json') as json_file:

    data = json.load(json_file)

Now the content of data is an array with dictionaries representing each of the elements.

You can access it easily, i.e:

data[0]["ID"]

If you're open to using javascript then you can get the property on an element like this: document.GetElementByID('rightdiv').style.getPropertyValue('max-height');

And you can set the attribute on an element like this: .setAttribute('style','max-height:'+heightVariable+';');

Note: if you're simply looking to set both element's max-height property in one line, you can do so like this:

#leftdiv,#rightdiv
{
    min-height: 600px;   
}

rawgit.com solves this problem nicely. For each request, it retrieves the appropriate document from GitHub and, crucially, serves it with the correct Content-Type header.

private String getDay(Date date){

    SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEEE");
    //System.out.println("DAY "+simpleDateFormat.format(date).toUpperCase());                       
    return simpleDateFormat.format(date).toUpperCase();
}

private String getDay(String dateStr){
    //dateStr must be in DD-MM-YYYY Formate
    Date date = null;
    String day=null;

    try {
        date = new SimpleDateFormat("DD-MM-YYYY").parse(dateStr);

        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("EEEE");
        //System.out.println("DAY "+simpleDateFormat.format(date).toUpperCase());
        day = simpleDateFormat.format(date).toUpperCase();


    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }


    return day;
}

As the error clearly states, OffenceBox.Text() is not a function and therefore doesn't make sense.

change() does not fire when a CSS class is added or removed or the definition changes. It fires in circumstances like when a select box value is selected or unselected.

I'm not sure if you mean if the CSS class definition is changed (which can be done programmatically but is tedious and not generally recommended) or if a class is added or removed to an element. There is no way to reliably capture this happening in either case.

You could of course create your own event for this but this can only be described as advisory. It won't capture code that isn't yours doing it.

Alternatively you could override/replace the addClass() (etc) methods in jQuery but this won't capture when it's done via vanilla Javascript (although I guess you could replace those methods too).

Another reason why someone might get this error is if the file Global.asax is not in the root folder anymore.

It is a way to simplify error checking and avoid deep nested if's. For example:

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

The 'file' protocol is not a network protocol. Therefore file://192.168.1.57/~User/2ndFile.html simply does not make much sense.

Question is how you load the first file. Is that really done using a web server? Does not really sound like. If it is, then why not use the same protocol, most likely http? You cannot expect to simply switch the protocol and use two different protocols the same way...

I suspect the first file is really loaded using the apache server at all, but simply by opening the file? href="2ndFile.html" simply works because it uses a "relative url". This makes the browser use the same protocol and path as where he got the first (current) file from.

The csh shell has never been known for its extensive ability to manipulate file handles in the redirection process.

You can redirect both standard output and error to a file with:

xxx >& filename

but that's not quite what you were after, redirecting standard error to the current standard output.

However, if your underlying operating system exposes the standard output of a process in the file system (as Linux does with /dev/stdout), you can use that method as follows:

xxx >& /dev/stdout

This will force both standard output and standard error to go to the same place as the current standard output, effectively what you have with the bash redirection, 2>&1.

Just keep in mind this isn't a csh feature. If you run on an operating system that doesn't expose standard output as a file, you can't use this method.

However, there is another method. You can combine the two streams into one if you send it to a pipeline with |&, then all you need to do is find a pipeline component that writes its standard input to its standard output. In case you're unaware of such a thing, that's exactly what cat does if you don't give it any arguments. Hence, you can achieve your ends in this specific case with:

xxx |& cat

Of course, there's also nothing stopping you from running bash (assuming it's on the system somewhere) within a csh script to give you the added capabilities. Then you can use the rich redirections of that shell for the more complex cases where csh may struggle.

Let's explore this in more detail. First, create an executable echo_err that will write a string to stderr:

#include <stdio.h>
int main (int argc, char *argv[]) {
    fprintf (stderr, "stderr (%s)\n", (argc > 1) ? argv[1] : "?");
    return 0;
}

Then a control script test.csh which will show it in action:

#!/usr/bin/csh

ps -ef ; echo ; echo $$ ; echo

echo 'stdout (csh)'
./echo_err csh

bash -c "( echo 'stdout (bash)' ; ./echo_err bash ) 2>&1"

The echo of the PID and ps are simply so you can ensure it's csh running this script. When you run this script with:

./test.csh >test.out 2>test.err

(the initial redirection is set up by bash before csh starts running the script), and examine the out/err files, you see:

test.out:
    UID     PID    PPID  TTY        STIME     COMMAND
    pax    5708    5364  cons0      11:31:14  /usr/bin/ps
    pax    5364    7364  cons0      11:31:13  /usr/bin/tcsh
    pax    7364       1  cons0      10:44:30  /usr/bin/bash

    5364

    stdout (csh)
    stdout (bash)
    stderr (bash)

test.err:
    stderr (csh)

You can see there that the test.csh process is running in the C shell, and that calling bash from within there gives you the full bash power of redirection.

The 2>&1 in the bash command quite easily lets you redirect standard error to the current standard output (as desired) without prior knowledge of where standard output is currently going.

anyway you have not a unlimited accuracy so C define a constant in this way:

#define PI 3.14159265358979323846

import math.h to use this

You can do it in one sql statement for existing customers, 3 statements for new ones. All you have to do is be an optimist and act as though the customer already exists:

insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

If the customer does not exist, you'll get an sql exception which text will be something like:

null value in column "customer_id" violates not-null constraint

(providing you made customer_id non-nullable, which I'm sure you did). When that exception occurs, insert the customer into the customer table and redo the insert into the order table:

insert into customer(name) values ('John');
insert into "order" (customer_id, price) values \
((select customer_id from customer where name = 'John'), 12.34);

Unless your business is growing at a rate that will make "where to put all the money" your only real problem, most of your inserts will be for existing customers. So, most of the time, the exception won't occur and you'll be done in one statement.

Both Redirect::to() and Redirect::away() should work.

Difference

Redirect::to() does additional URL checks and generations. Those additional steps are done in Illuminate\Routing\UrlGenerator and do the following, if the passed URL is not a fully valid URL (even with protocol):

Determines if URL is secure
rawurlencode() the URL
trim() URL

src : https://medium.com/@zwacky/laravel-redirect-to-vs-redirect-away-dd875579951f

Follow these steps:

1. Add path to gitignore file

2. Run this command

   git rm -r --cached foldername
   

3. commit changes as usually.

You can use the Gson library for parsing

void getJson() throws IOException {
    HttpClient  httpClient = new DefaultHttpClient();
    HttpGet httpGet = new HttpGet("some url of json");
    HttpResponse httpResponse = httpClient.execute(httpGet);
    String response = EntityUtils.toString(httpResponse.getEntity());

    Gson gson = new Gson();
    MyClass myClassObj = gson.fromJson(response, MyClass.class);

}

here is sample json file which is fetchd from server

{
"id":5,
"name":"kitkat",
"version":"4.4"
}

here is my class

class MyClass{
int id;
String name;
String version;
}

refer this

in swift 3.0 this is how we can convert Int to String and String to Int

//convert Integer to String in Swift 3.0

let theIntegerValue :Int = 123  // this can be var also
let theStringValue :String = String(theIntegerValue)


//convert String to Integere in Swift 3.0


let stringValue : String = "123"
let integerValue : Int = Int(stringValue)!

Parsing can be considered as a synonym of "Breaking down into small pieces" and then analysing what is there or using it in a modified way. In Java, Strings are parsed into Decimal, Octal, Binary, Hexadecimal, etc. It is done if your application is taking input from the user in the form of string but somewhere in your application you want to use that input in the form of an integer or of double type. It is not same as type casting. For type casting the types used should be compatible in order to caste but nothing such in parsing.

I have been looking for the same case and tried all answers by change the width of <li>.
Unfortunately all were failed to get the same distance on left and right of the <ul> box.

The closest match is this answer but it needs to adjust the change of width with padding

.container ul {
    ...
    padding: 10px 25px;
}

.container li {
  ...
  width: 100px;
}

See the result below, all distance between <li> also to the <ul> box are the same.

You may check it on this jsFiddle:
http://jsfiddle.net/qwbexxog/14/

You can give below code a try,

public void multiArrayCopy(int[][] source,int[][] destination){
destination=source.clone();}

Hope it works.

Another ViewGroup:

A fragment is a ViewGroup which can be shown in an Activity. But it needs a Container. The container can be any Layout (FragmeLayout, LinearLayout, etc. It does not matter).

Step 1:

Define Activity Layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
   android:layout_width="match_parent"
   android:layout_height="match_parent">
   <FrameLayout
       android:id="@+id/fragmentHolder"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
    />
</RelativeLayout>

Step 2:

Define Fragment Layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">
    <EditText
       android:id="@+id/user"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"/>
    <EditText
       android:id="@+id/password"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:inputType="textPassword"/>
    <Button
       android:id="@+id/login"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Login"/>
</LinearLayout>

Step 3:

Create Fragment class

public class LoginFragment extends Fragment {


    private Button login;
    private EditText username, password;

    public static LoginFragment getInstance(String username){
       Bundle bundle = new Bundle();
       bundle.putInt("USERNAME", username);
       LoginFragment fragment = new LoginFragment();
       fragment.setArguments(bundle);
       return fragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){
       View view = inflater.inflate(R.layout.login_fragment, parent, false);
       login = view.findViewById(R.id.login);
       username = view.findViewById(R.id.user);
       password = view.findViewById(R.id.password);
       String name = getArguments().getInt("USERNAME");
       username.setText(username);
       return view;
    }

}

Step 4:

Add fragment in Activity

public class ActivityB extends AppCompatActivity{

   private Fragment currentFragment;

   @Override
   protected void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_main);

       currentFragment = LoginFragment.getInstance("Rohit");
       getSupportFragmentManager()
                .beginTransaction()
                .add(R.id.fragmentHolder, currentFragment, "LOGIN_TAG")
                .commit();
   }

}

REASON

This happens because for now they only ship 64bit JRE with Android Studio for Windows which produces glitches in 32 bit systems.

SOLUTION

• do not use the embedded JDK: Go to File -> Project Structure dialog, uncheck "Use embedded JDK" and select the 32-bit JRE you've installed separately in your system
• decrease the memory footprint for Gradle in gradle.properties(Project Properties), for eg set it to -Xmx768m.

For some reason only this worked for me today. All other variants ended up in bad json error from API.

Besides, yet another variant for creating required POST request with JSON payload.

request.post({_x000D_
    uri: 'https://www.googleapis.com/urlshortener/v1/url',_x000D_
    headers: {'Content-Type': 'application/json'},_x000D_
    body: JSON.stringify({"longUrl": "http://www.google.com/"})_x000D_
});

According to Froyo source code, the Intent.EXTRA_INSTALLER_PACKAGE_NAME extra key is queried for the installer package name in the PackageInstallerActivity.

Here's a short, simple generic answer with a nice syntax for a named tuple with default arguments:

import collections

def dnamedtuple(typename, field_names, **defaults):
    fields = sorted(field_names.split(), key=lambda x: x in defaults)
    T = collections.namedtuple(typename, ' '.join(fields))
    T.__new__.__defaults__ = tuple(defaults[field] for field in fields[-len(defaults):])
    return T

Usage:

Test = dnamedtuple('Test', 'one two three', two=2)
Test(1, 3)  # Test(one=1, three=3, two=2)

Minified:

def dnamedtuple(tp, fs, **df):
    fs = sorted(fs.split(), key=df.__contains__)
    T = collections.namedtuple(tp, ' '.join(fs))
    T.__new__.__defaults__ = tuple(df[i] for i in fs[-len(df):])
    return T

This is the way I did it:

I just put

Intent intent = new Intent(Main.this, SOMECLASSNAME.class);
Main.this.startActivityForResult(intent, 0);

inside of the method that opens an activity, then inside of the method of SOMECLASSNAME that is designed to close the app I put:

setResult(0);
finish();

And I put the following in my Main class:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(resultCode == 0) {
        finish();
    }
}

It is very easy to do. Just follow two steps:

1. Right click on root folder and click on open module settings.

2. After this go to flavors tab and change application id as you wish.

For those who are thinking that this will only change the application id in build.gradle file:

It is written by Google that

The final package that is used in your built .apk's manifest, and is the package your app is known as on your device and in the Google Play store, is the "application id".

and

The package that is used in your source code to refer to your R class, and to resolve any relative activity/service registrations, continues to be called the "package".

You can read more on http://tools.android.com/tech-docs/new-build-system/applicationid-vs-packagename

I can't answer the why part.

But if you want something dynamic then why don't you consider Collection ArrayList.

ArrrayList can be of any Object type.

And if as an compulsion you want it as an array you can use the toArray() method on it.

For example:

            ArrayList<String> al = new ArrayList<String>();
            al.add("one");
            al.add("two");
            String[] strArray = (String[]) al.toArray(new String[0]);

I hope this might help you.

The correct answer:

$window.location.reload(true);

All you want is the below regex:

^\d+$

Update: This answer is old. Intellij has since added actions to adjust font size. Check out Wilker's answer for assigning the new actions to keymaps.

Try Ctrl+Mouse Wheel which can be enabled under File > Settings... > Editor > General : Change font size (Zoom) with Ctrl+Mouse Wheel

Your flex items have

flex: 0 0 200px; /* <aside> */
flex: 1 0 auto;  /* <article> */ 

That means:

• The <aside> will start at 200px wide.

  Then it won't grow nor shrink.

• The <article> will start at the width given by the content.

  Then, if there is available space, it will grow to cover it.

  Otherwise it won't shrink.

To prevent horizontal overflow, you can:

• Use flex-basis: 0 and then let them grow with a positive flex-grow.
• Use a positive flex-shrink to let them shrink if there isn't enough space.

To prevent vertical overflow, you can

• Use min-height instead of height to allow the flex items grow more if necessary
• Use overflow different than visible on the flex items
• Use overflow different than visible on the flex container

For example,

main, aside, article {
  margin: 10px;
  border: solid 1px #000;
  border-bottom: 0;
  min-height: 50px; /* min-height instead of height */
}
main {
  display: flex;
}
aside {
  flex: 0 1 200px; /* Positive flex-shrink */
}
article {
  flex: 1 1 auto; /* Positive flex-shrink */
}

<main>
  <aside>x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x x </aside>
  <article>don't let flex item overflow container.... y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y y </article>
</main>

@Carlo I really like your implementation of this, but I wanted to share my version and how to use it in my ViewModel

First implement ICommand

public class Command : ICommand
{
    public delegate void ICommandOnExecute();
    public delegate bool ICommandOnCanExecute();

    private ICommandOnExecute _execute;
    private ICommandOnCanExecute _canExecute;

    public Command(ICommandOnExecute onExecuteMethod, ICommandOnCanExecute onCanExecuteMethod = null)
    {
        _execute = onExecuteMethod;
        _canExecute = onCanExecuteMethod;
    }

    #region ICommand Members

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    public bool CanExecute(object parameter)
    {
        return _canExecute?.Invoke() ?? true;
    }

    public void Execute(object parameter)
    {
        _execute?.Invoke();
    }

    #endregion
}

Notice I have removed the parameter from ICommandOnExecute and ICommandOnCanExecute and added a null to the constructor

Then to use in the ViewModel

public Command CommandToRun_WithCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        }, () =>
        {
            // Code to check to see if we can run 
            // Return true or false
        });
    }
}

public Command CommandToRun_NoCheck
{
    get
    {
        return new Command(() =>
        {
            // Code to run
        });
    }
}

I just find this way cleaner as I don't need to assign variables and then instantiate, it all done in one go.

private double ConvertToDouble(string s)
    {
        char systemSeparator = Thread.CurrentThread.CurrentCulture.NumberFormat.CurrencyDecimalSeparator[0];
        double result = 0;
        try
        {
            if (s != null)
                if (!s.Contains(","))
                    result = double.Parse(s, CultureInfo.InvariantCulture);
                else
                    result = Convert.ToDouble(s.Replace(".", systemSeparator.ToString()).Replace(",", systemSeparator.ToString()));
        }
        catch (Exception e)
        {
            try
            {
                result = Convert.ToDouble(s);
            }
            catch
            {
                try
                {
                    result = Convert.ToDouble(s.Replace(",", ";").Replace(".", ",").Replace(";", "."));
                }
                catch {
                    throw new Exception("Wrong string-to-double format");
                }
            }
        }
        return result;

Just check the dictionary:

d = {'hello':'world'}
if d:
  print 'not empty'
else:
  print 'empty'

d = {}
if d:
  print 'not empty'
else:
  print 'empty'

In your app or server.js file include this line:

app.use(express.static('public'));

In your index.ejs, following line will help you:

<link rel="stylesheet" type="text/css" href="/css/style.css" />

I hope this helps, it did for me!

I'm a fan of the Find-In-Files dialog in Notepad++. Bonus: It's free.

It is included with .NET (not sure if only in the SDK).

I'm using

Sheet1.Range("E2", "E3000").NumberFormat = "dd/mm/yyyy hh:mm:ss"

to format a column

So I guess

Sheet1.Range("E2", "E3000").NumberFormat = "MMM dd yyyy"

would do the trick for you.

More: NumberFormat function.

Download it from here:

http://www.iis.net/downloads/microsoft/url-rewrite

or if you already have Web Platform Installer on your machine you can install it from there.

Use array_values to reset keys

foreach($input as &$val) {
   $val = array_values($val);
}

You might want to consider using a div element pop-up window that contains an iframe.

jQuery Dialog is a simple way to get started. Just add an iframe as the content.

It's far from pretty, but you could create a script or an alias that does something like this:

for c in $(git for-each-ref refs/tags/ --format='%(refname)'); do echo $c; git show --quiet "$c"; echo; done

The steps to apply a theme are fairly simple. To really understand how everything works together, you'll need to understand what the ASP.NET MVC 5 template is providing out of the box and how you can customize it for your needs.

_{Note: If you have a basic understanding of how the MVC 5 template works, scroll down to the theming section.}

ASP.NET MVC 5 Template: How it works

This walk-through goes over how to create an MVC 5 project and what's going on under the hood. See all the features of MVC 5 Template in this blog.

1. Create a new project. Under Templates Choose Web > ASP.NET Web Application. Enter a name for your project and click OK.

2. On the next wizard, choose MVC and click OK. This will apply the MVC 5 template.

   

3. The MVC 5 template creates an MVC application that uses Bootstrap to provide responsive design and theming features. Under the hood, the template includes a bootstrap 3.* nuget package that installs 4 files: bootstrap.css, bootstrap.min.css, bootstrap.js, and bootstrap.min.js.

   

4. Bootstrap is bundled in your application by using the Web Optimization feature. Inspect Views/Shared/_Layout.cshtml and look for

   @Styles.Render("~/Content/css")
   

   and

   @Scripts.Render("~/bundles/bootstrap") 
   

   These two paths refer to bundles set up in App_Start/BundleConfig.cs:

   bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
       "~/Scripts/bootstrap.js",
       "~/Scripts/respond.js"));
   
   bundles.Add(new StyleBundle("~/Content/css").Include(
       "~/Content/bootstrap.css",
       "~/Content/site.css"));
   

5. This is what makes it possible to run your application without any configuring up front. Try running your project now.

   

Applying Bootstrap Themes in ASP.NET MVC 5

This walk-through covers how to apply bootstrap themes in an MVC 5 project

1. First, download the css of the theme you'd like to apply. For this example, I'll be using Bootswatch's Flatly. Include the downloaded flatly.bootstrap.css and flatly.bootstrap.min.css in the Content folder (be sure to Include in Project as well).

2. Open App_Start/BundleConfig.cs and change the following:

   bundles.Add(new StyleBundle("~/Content/css").Include(
       "~/Content/bootstrap.css",
       "~/Content/site.css"));
   

   to include your new theme:

   bundles.Add(new StyleBundle("~/Content/css").Include(
       "~/Content/flatly.bootstrap.css",
       "~/Content/site.css"));
   

3. If you're using the default _Layout.cshtml included in the MVC 5 template, you can skip to step 4. If not, as a bare minimum, include these two line in your layout along with your Bootstrap HTML template:

   In your <head>:

   @Styles.Render("~/Content/css")
   

   Last line before closing </body>:

   @Scripts.Render("~/bundles/bootstrap")
   

4. Try running your project now. You should see your newly created application now using your theme.

BREAKING BAD NEWS for "style in body" lovers: W3C has recently lost the HTML war against WHATWG, whose versionless HTML "Living Standard" has now become the official one, which, alas, does not allow STYLE in the BODY. The short-lived happy days are over. ;) The W3C validator also works by the WHATWG specs now. (Thanks @FrankConijn for the heads-up!)

(Note: this is the case "as of today", but since there's no versioning, links can become invalid at any moment without notice or control. Unless you're willing to link to its individual source commits at GitHub, you basically can no longer make stable references to the new official HTML standard, AFAIK. Please correct me if there's a canonical way of doing this properly.)

OBSOLETED GOOD NEWS:

Yay, STYLE is finally valid in BODY, as of HTML5.2! (And scoped is gone, too.)

From the W3C specs (relish the last line!):

4.2.6. The style element

...

Contexts in which this element can be used:

Where metadata content is expected.

In a noscript element that is a child of a head element.

In the body, where flow content is expected.

META SIDE-NOTE:

The mere fact that despite the damages of the "browser war" we still had to keep developing against two ridiculously competing "official" HTML "standards" (quotes for 1 standard + 1 standard < 1 standard) means that the "fallback to in-the-trenches common sense" approach to web development has never really ceased to apply.

This may finally change now, but citing the conventional wisdom: web authors/developers and thus, in turn, browsers should ultimately decide what should (and shouldn't) be in the specifications, when there's no good reason against what's already been done in reality. And most browsers have long supported STYLE in BODY (in one way or another; see e.g. the scoped attr.), despite its inherent performance (and possibly other) penalties (which we should decide to pay or not, not the specs.). So, for one, I'll keep betting on them, and not going to give up hope. ;) If WHATWG has the same respect for reality/authors as they claim, they may just end up doing here what the W3C did.

Add a parameter of type UriComponentsBuilder to your controller method. Spring will give you an instance that's preconfigured with the URI for the current request, and you can then customize it (such as by using MvcUriComponentsBuilder.relativeTo to point at a different controller using the same prefix).

byte[] a = new byte[50];

char [] cArray= System.Text.Encoding.ASCII.GetString(a).ToCharArray();

From the URL thedixon posted

http://bytes.com/topic/c-sharp/answers/250261-byte-char

You cannot ToCharArray the byte without converting it to a string first.

To quote Jon Skeet there

There's no need for the copying here - just use Encoding.GetChars. However, there's no guarantee that ASCII is going to be the appropriate encoding to use.

The problem shall have solved if you specify your path.

e.g.

"require 'st.rb'" --> "require './st.rb'"

See if your problem get solved or not.

Easy solution: Check if it works for you..

Goto web.config

Find binding used by client.

change as,

maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"

Done.

The syntax of the query is as follows:

Alter table <table name> rename column <column name> to <new column name>;

Example:

Alter table employee rename column eName to empName;

To rename a column name without space to a column name with space:

Alter table employee rename column empName to "Emp Name";

To rename a column with space to a column name without space:

Alter table employee rename column "emp name" to empName;

The default timeout is 900 second. You can specify different timeout.

-T seconds
--timeout=seconds

The default is to retry 20 times. You can specify different tries.

-t number
--tries=number

You could also position the hidden div off the screen with a negative margin rather than using display:none, much like a the text indent image replacement technique.

eg.

position:absolute;
left:  -2000px;
top: 0;

This way the height() is still available.

Another—as of yet unmentioned—reason for favoring pip is because it is the new hotness and will continue to be used in the future.

The infographic below—from the Current State of Packaging section in the The Hitchhiker's Guide to Packaging v1.0—shows that setuptools/easy_install will go away in the future.

Here's another infographic from distribute's documentation showing that Setuptools and easy_install will be replaced by the new hotness—distribute and pip. While pip is still the new hotness, Distribute merged with Setuptools in 2013 with the release of Setuptools v0.7.

Run: python -c "import ssl; print(ssl.get_default_verify_paths())" to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.

The path openssl_capath_env points to the environment variable: SSL_CERT_DIR.

If SSL_CERT_DIR doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.

I'd recommend Replace in lieu of Substring to avoid string length issues:

REPLACE(CONVERT(varchar(20), (CAST(SUM(table.value) AS money)), 1), '.00', '')

I am a beginner with Angular and I did the basic mistake of not including the app name in the angular root element. So, changing the code from

<html data-ng-app> 

to

<html data-ng-app="myApp"> 

worked for me. @PSL, has covered this already in his answer above.

You can pass an array as the first AutoFilter argument and use the xlFilterValues operator.

This will display PDF, DOC and DOCX filetypes.

Criteria1:=Array(".pdf", ".doc", ".docx"), Operator:=xlFilterValues

In some ways, your question seems very legitimate, but I still might label it an XY problem. I'm guessing the end result is that you want to display the sorted values in some way? As Bergi said in the comments, you can never quite rely on Javascript objects ( {i_am: "an_object"} ) to show their properties in any particular order.

For the displaying order, I might suggest you take each key of the object (ie, i_am) and sort them into an ordered array. Then, use that array when retrieving elements of your object to display. Pseudocode:

var keys = [...]
var sortedKeys = [...]
for (var i = 0; i < sortedKeys.length; i++) {
  var key = sortedKeys[i];
  addObjectToTable(json[key]);
}

This problem can be caused by requests for certain files that don't exist. For example, requests for files in wp-content/uploads/ where the file does not exist.

If this is the situation you're seeing, you can solve the problem by going to .htaccess and changing this line:

RewriteRule ^(wp-(content|admin|includes).*) $1 [L]

to:

RewriteRule ^(wp-(content|admin|includes).*) - [L]

The underlying issue is that the rule above triggers a rewrite to the exact same url with a slash in front and because there was a rewrite, the newly rewritten request goes back through the rules again and the same rule is triggered. By changing that line's "$1" to "-", no rewrite happens and so the rewriting process does not start over again with the same URL.

It's possible that there's a difference in how apache 2.2 and 2.4 handle this situation of only-difference-is-a-slash-in-front and that's why the default rules provided by WordPress aren't working perfectly.

Instead of System.exit(1) Just use System.exit(0)

import string
import random

KEY_LEN = 20

def base_str():
    return (string.letters+string.digits)   
def key_gen():
    keylist = [random.choice(base_str()) for i in range(KEY_LEN)]
    return ("".join(keylist))

You can get random strings like this:

g9CtUljUWD9wtk1z07iF
ndPbI1DDn6UvHSQoDMtd
klMFY3pTYNVWsNJ6cs34
Qgr7OEalfhXllcFDGh2l

Instead of having to create a function in the ts file you can toggle a variable from the template itself. You can then use the variable to apply a specific class to the element. Like so-

<div (click)="status=!status"  
    [ngClass]="status ? 'success' : 'danger'">                
     Some content
</div>

So when status is true the class success is applied. When it is false danger class is applied.

This will work without any additional code in the ts file.

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

Xcode 8 and Swift 3: Array can be enumerated using tempArray.enumerated()

Example:

var someStrs = [String]()

someStrs.append("Apple")  
someStrs.append("Amazon")  
someStrs += ["Google"]    


for (index, item) in someStrs.enumerated()  
{  
        print("Value at index = \(index) is \(item)").  
}

console:

Value at index = 0 is Apple
Value at index = 1 is Amazon
Value at index = 2 is Google

Depends on what you mean by emptying. If you just want an empty string, you could do

buffer[0] = 0;

If you want to set every element to zero, do

memset(buffer, 0, 80);

self.parent is a reference to the actual window, so self.root.title should be self.parent.title, and self.root shouldn't exist.

One way is to use the lattice package and xyplot():

R> DF <- data.frame(x=1:10, y=rnorm(10)+5, 
+>                  z=sample(letters[1:3], 10, replace=TRUE))
R> DF
    x       y z
1   1 3.91191 c
2   2 4.57506 a
3   3 3.16771 b
4   4 5.37539 c
5   5 4.99113 c
6   6 5.41421 a
7   7 6.68071 b
8   8 5.58991 c
9   9 5.03851 a
10 10 4.59293 b
R> with(DF, xyplot(y ~ x, group=z))

By giving explicit grouping information via variable z, you obtain different colors. You can specify colors etc, see the lattice documentation.

Because z here is a factor variable for which we obtain the levels (== numeric indices), you can also do

R> with(DF, plot(x, y, col=z))

but that is less transparent (to me, at least :) then xyplot() et al.

<section [ngClass]="{'class1': expression1, 'class2': expression2, 
'class3': expression3}">

Don't forget to add single quotes around class names.

For the folks who are using Java based Spring configuration:

@Configuration
@ComponentScan(basePackages = "com.domain.sample")
@EnableWebMvc
public class SpringConfig extends WebMvcConfigurerAdapter {
....

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        final MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
        final ObjectMapper objectMapper = new ObjectMapper();
        objectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
        converter.setObjectMapper(objectMapper);
        converters.add(converter);
        super.configureMessageConverters(converters);
    }

....

}

I'm using MappingJackson2HttpMessageConverter - which is from fasterxml.

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.3.1</version>
</dependency>

If you want to use codehaus-jackson mapper, instead use this one MappingJacksonHttpMessageConverter

 <dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>${codehaus.jackson.version}</version>
 </dependency>

Below is the configuration in Maven software by default in MAVEN_HOME\conf\settings.xml.

<settings>
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ~/.m2/repository
  <localRepository>/path/to/local/repo</localRepository>
  -->

Add the below line under this configuration, will fulfill the requirement.

<localRepository>custom_path</localRepository>

Ex: <localRepository>D:/MYNAME/settings/.m2/repository</localRepository>

Not sure from what version, but I use 1.3.14 and you can just use:

window.location.href = '/employee/1';

No need to inject $location or $window in the controller and no need to get the current host address.

simple and easy

Locale locale = new Locale("en", "US");
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = locale;
res.updateConfiguration(conf, dm);

where "en" is language code and "US" is country code.

You can convert a datetime object to a date with the date() method of the date time object, as follows:

<datetime_object>.date()

swift 5 and above

case 1 : using with Navigation controller

self.navigationController?.popViewController(animated: true)

case 2 : using with present view controller

self.dismiss(animated: true, completion: nil)

If you want to create a temp table after check exist table.You can use the following code

DROP TABLE IF EXISTS tempdb.dbo.#temptable
CREATE TABLE #temptable
  (
   SiteName             NVARCHAR(50),
   BillingMonth         varchar(10),
   Consumption          INT,
  )

After creating the temporary table, you can insert data into this table as a regular table:

INSERT INTO #temptable
SELECT COLUMN1,...
FROM
(...)

or

INSERT INTO #temptable
VALUES (value1, value2, value3, ...);

The SELECT statement is used to select data from a temp table.

SELECT * FROM #temptable

you can manually remove the temporary table by using the DROP TABLE statement:

DROP TABLE #temptable;

Assuming the title of your question is correct and you want the time:

SELECT CONVERT(char,GETDATE(),14) 

Edited to include millisecond.

Just put some CSS into the stylesheet like this

form {
  text-align: center;
}

then you're done!

When you want a flex item to occupy an entire row, set it to width: 100% or flex-basis: 100%, and enable wrap on the container.

The item now consumes all available space. Siblings are forced on to other rows.

.parent {
  display: flex;
  flex-wrap: wrap;
}

#range, #text {
  flex: 1;
}

.error {
  flex: 0 0 100%; /* flex-grow, flex-shrink, flex-basis */
  border: 1px dashed black;
}

<div class="parent">
  <input type="range" id="range">
  <input type="text" id="text">
  <label class="error">Error message (takes full width)</label>
</div>

More info: The initial value of the flex-wrap property is nowrap, which means that all items will line up in a row. MDN

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

Given that a WHERE clause did not work, maybe this will:

The author asked for explode, to you can use explode like this

$resultArray = explode("\t", $inputString);

Note: you must used double quote, not single.

Reset - On the commit-level, resetting is a way to move the tip of a branch to a different commit. This can be used to remove commits from the current branch.

Revert - Reverting undoes a commit by creating a new commit. This is a safe way to undo changes, as it has no chance of re-writing the commit history. Contrast this with git reset, which does alter the existing commit history. For this reason, git revert should be used to undo changes on a public branch, and git reset should be reserved for undoing changes on a private branch.

You can have a look on this link- Reset, Checkout and Revert

This can be confusing for anyone using nodejs for the first time. It is actually possible to pipe your node console output to the browser console. Take a look at connect-browser-logger on github

UPDATE: As pointed out by Yan, connect-browser-logger appears to be defunct. I would recommend NodeMonkey as detailed here : Output to Chrome console from Node.js

Update with Spring Boot 2.2.2.Release.

Full example here, https://www.surasint.com/spring-boot-override-property-example/

Assume that, in your jar file, you have the application.properties which have these two line:

server.servlet.context-path=/test
server.port=8081

Then, in production, you want to override the server.port=8888 but you don't want to override the other properties.

First you create another file, ex override.properties and have online this line:

server.port=8888

Then you can start the jar like this

java -jar spring-boot-1.0-SNAPSHOT.jar --spring.config.location=classpath:application.properties,/opt/somewhere/override.properties

To clear the whole thing use the reset_session method in a controller.

reset_session

Here's the documentation on this method: http://api.rubyonrails.org/classes/ActionController/Base.html#M000668

Resets the session by clearing out all the objects stored within and initializing a new session object.

Good luck!

If you need to scroll to the EXACT end of the content, you can do it like this:

- (void)scrollToBottom
{
    CGFloat yOffset = 0;

    if (self.tableView.contentSize.height > self.tableView.bounds.size.height) {
        yOffset = self.tableView.contentSize.height - self.tableView.bounds.size.height;
    }

    [self.tableView setContentOffset:CGPointMake(0, yOffset) animated:NO];
}

You can use a script from udhos/update-golang.

Here is a two-liner as example (run as root):

bash <(curl -s https://raw.githubusercontent.com/udhos/update-golang/master/update-golang.sh)
ln -vs /usr/local/go/bin/go* /usr/local/bin/

Another way using dictionary comprehensions,

>>> t = [('A', 1), ('B', 2), ('C', 3)]
>>> d = { i:j for i,j in t }
>>> d
{'A': 1, 'B': 2, 'C': 3}

For anyone looking to do this dynamically then setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom) on the buttons object will assist.

Sample

Button search = (Button) findViewById(R.id.yoursearchbutton);
search.setCompoundDrawables('your_drawable',null,null,null);

Yes. You can use HTMLUnitDriver instead for FirefoxDriver while starting webdriver. This is headless browser setup. Details can be found here.

A double quote character (") can be escaped as ", but here's the rest of the story...

Double quote character must be escaped in this context:

• In XML attributes delimited by double quotes:

  <EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
  

Double quote character need not be escaped in most contexts:

• In XML textual content:

  <NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
  

• In XML attributes delimited by single quotes ('):

  <NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
  

  Similarly, (') require no escaping if (") are used for the attribute value delimiters:

  <NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>
  

See also

• Simplified XML Escaping

for example:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="42dp"  
  android:maxHeight="42dp"  
  android:scaleType="fitCenter"  
  android:layout_marginLeft="3dp"  
  android:src="@drawable/icon"  
  /> 

Add property android:scaleType="fitCenter" and android:adjustViewBounds="true".

Move all of your state and your handleClick function from Header to your MainWrapper component.

Then pass values as props to all components that need to share this functionality.

class MainWrapper extends React.Component {
    constructor() {
        super();
        this.state = {
            sidbarPushCollapsed: false,
            profileCollapsed: false
        };
        this.handleClick = this.handleClick.bind(this);
    }
    handleClick() {
        this.setState({
            sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
            profileCollapsed: !this.state.profileCollapsed

        });
    }
    render() {
        return (
           //...
           <Header 
               handleClick={this.handleClick} 
               sidbarPushCollapsed={this.state.sidbarPushCollapsed}
               profileCollapsed={this.state.profileCollapsed} />
        );

Then in your Header's render() method, you'd use this.props:

<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>

Replace the whitespace characters, and then convert it(using the intval function or by regular typecasting)

intval(str_replace(" ", "", $b))

Use a name. Using an id isn't necessary in HTML 5 and will create global variables in your JavaScript

See the HTML 5 specification, 5.9.8 Navigating to a fragment identifier - both id and name are used.

It's important to know that most browsers still turn IDs into global variables. Here's a quick test. Using a name avoids creating globals and any conflicts that may result.

Example using a name:

Take me to [pookie](#pookie)

And the destination anchor:

### <a name="pookie"></a>Some heading

For those who might be trying to create a Travis Build, the default path from which Django is installed from the requirements.txt file points to a repo whose django_extensions module has not been updated. The only workaround, for now, is to install from the master branch using pip. That is where the patch is made. But for now, we'll have to wait.

You can try this in the meantime, it might help

- pip install git+https://github.com/chibisov/drf-extensions.git@master

- pip install git+https://github.com/django-extensions/django-extensions.git@master

To align some elements (headerElement) in the center and the last element to the right (headerEnd).

.headerElement {
    margin-right: 5%;
    margin-left: 5%;
}
.headerEnd{
    margin-left: auto;
}

#!/bin/bash                                                                                                                                                                                     
CURL='/usr/bin/curl'
RVMHTTP="https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer"
CURLARGS="-f -s -S -k"

# you can store the result in a variable
raw="$($CURL $CURLARGS $RVMHTTP)"

# or you can redirect it into a file:

Below is what worked for me -

QUOTE="'"
hive -e "alter table TBL_NAME set location $QUOTE$TBL_HDFS_DIR_PATH$QUOTE"

It seems like there would be a more Pythonic way of doing this, but I haven't found it yet.

I use "map" sometimes if I'm calling the same function (not a method) on a bunch of objects:

map(do_something, a_list_of_objects)

This replaces a bunch of code that looks like this:

 do_something(a)
 do_something(b)
 do_something(c)
 ...

But can also be achieved with a pedestrian "for" loop:

  for obj in a_list_of_objects:
       do_something(obj)

The downside is that a) you're creating a list as a return value from "map" that's just being throw out and b) it might be more confusing that just the simple loop variant.

You could also use a list comprehension, but that's a bit abusive as well (once again, creating a throw-away list):

  [ do_something(x) for x in a_list_of_objects ]

For methods, I suppose either of these would work (with the same reservations):

map(lambda x: x.method_call(), a_list_of_objects)

or

[ x.method_call() for x in a_list_of_objects ]

So, in reality, I think the pedestrian (yet effective) "for" loop is probably your best bet.

I don't necessarily recommend this (it's more efficient to work with the number rather than converting it to a string), but it's easy and it works :)

#include <algorithm>
#include <iostream>
#include <iterator>
#include <string>

#include <boost/lexical_cast.hpp>

int main()
{
    int n = 23984;
    std::string s = boost::lexical_cast<std::string>(n);
    std::copy(s.begin(), s.end(), std::ostream_iterator<char>(std::cout, "\n"));
    return 0;
}

I forgot to mention. This should also accept whitespace.

You could use:

/^[-@.\/#&+\w\s]*$/

Note how this makes use of the character classes \w and \s.

EDIT:- Added \ to escape /

Maybe, you can use moment.js which in my opinion is the best JavaScript library for parsing, formatting and working with dates client-side. You could use something like:

var momentDate = moment('1890-09-30T23:59:59+01:16:20', 'YYYY-MM-DDTHH:mm:ss+-HH:mm:ss');_x000D_
var jsDate = momentDate.toDate();_x000D_
_x000D_
// Now, you can run any JavaScript Date method_x000D_
_x000D_
jsDate.toLocaleString();

The advantage of using a library like moment.js is that your code will work perfectly even in legacy browsers like IE 8+.

Here is the documenation about parsing methods: https://momentjs.com/docs/#/parsing/

>>> def delete_key(dict, key):
...     del dict[key]
...     return dict
... 
>>> test_dict = {'one': 1, 'two' : 2}
>>> print delete_key(test_dict, 'two')
{'one': 1}
>>>

this doesn't do any error handling, it assumes the key is in the dict, you might want to check that first and raise if its not

Why don't you try using Context?

You can declare a global context variable in any of the parent components and this variable will be accessible across the component tree by this.context.varname. You only have to specify childContextTypes and getChildContext in the parent component and thereafter you can use/modify this from any component by just specifying contextTypes in the child component.

However, please take a note of this as mentioned in docs:

Just as global variables are best avoided when writing clear code, you should avoid using context in most cases. In particular, think twice before using it to "save typing" and using it instead of passing explicit props.

import zipfile
with zipfile.ZipFile(path_to_zip_file, 'r') as zip_ref:
    zip_ref.extractall(directory_to_extract_to)

That's pretty much it!

I managed to solve this issue with this call

Properties props = PropertiesUtil.loadProperties("whatever.properties");

Extra, you have to put your whatever.properties file in /src/main/resources

To resolve your problem, write the following line on your page's Page_Load method.

if (String.IsNullOrEmpty(Request.QueryString["aspxerrorpath"])) return;

.Net 4.0 provides more closer look to null, empty or whitespace strings, use it as shown in the following line:

if(string.IsNullOrWhiteSpace(Request.QueryString["aspxerrorpath"])) return;

This will not run your next statements (your business logics) if query string does not have aspxerrorpath.

Based on quick inspection of google web, this would be CSS path to links in page list

ol[id="rso"] h3[class="r"] a

So you should do something like

String path = "ol[id='rso'] h3[class='r'] a";
driver.findElements(By.cssSelector(path)).get(2).click();

However you could also use xpath which is not really recommended as a best practice and also JQuery locators but I am not sure if you can use them aynywhere else except inArquillian Graphene

Casting should be enough. If you're using C# 3.0 you can make a handy extension method to parse enum values:

public static TEnum ToEnum<TInput, TEnum>(this TInput value)
{
    Type type = typeof(TEnum);

    if (value == default(TInput))
    {
        throw new ArgumentException("Value is null or empty.", "value");
    }

    if (!type.IsEnum)
    {
        throw new ArgumentException("Enum expected.", "TEnum");
    }

    return (TEnum)Enum.Parse(type, value.ToString(), true);
}

This should work fine.

    Workbook wb = new XSSFWorkbook("myWorkbook.xlsx");
    Row row=sheet.getRow(0);
    CellStyle style=null;

    XSSFFont defaultFont= wb.createFont();
    defaultFont.setFontHeightInPoints((short)10);
    defaultFont.setFontName("Arial");
    defaultFont.setColor(IndexedColors.BLACK.getIndex());
    defaultFont.setBold(false);
    defaultFont.setItalic(false);

    XSSFFont font= wb.createFont();
    font.setFontHeightInPoints((short)10);
    font.setFontName("Arial");
    font.setColor(IndexedColors.WHITE.getIndex());
    font.setBold(true);
    font.setItalic(false);

    style=row.getRowStyle();
    style.setFillBackgroundColor(IndexedColors.DARK_BLUE.getIndex());
    style.setFillPattern(CellStyle.SOLID_FOREGROUND);
    style.setAlignment(CellStyle.ALIGN_CENTER);
    style.setFont(font);

If you do not create defaultFont all your workbook will be using the other one as default.

start did not work for me.

I used:

firefox http://www.stackoverflow.com

or

chrome http://www.stackoverflow.com

Obviously not great for distributing it, but if you're using it for a specific machine, it should work fine.

I think this method my solve your problem:

public static void attachFragment ( int fragmentHolderLayoutId, Fragment fragment, Context context, String tag ) {


    FragmentManager manager = ( (AppCompatActivity) context ).getSupportFragmentManager ();
    FragmentTransaction ft = manager.beginTransaction ();

    if (manager.findFragmentByTag ( tag ) == null) { // No fragment in backStack with same tag..
        ft.add ( fragmentHolderLayoutId, fragment, tag );
        ft.addToBackStack ( tag );
        ft.commit ();
    }
    else {
        ft.show ( manager.findFragmentByTag ( tag ) ).commit ();
    }
}

For VS2008, I believe RDL gives you better editing features than RDLC. For example, I can change the Bold on a selected amount of text in a textbox with RDL, while in RDLC it's is not possible.

RDL: abcd efgh ijklmnop

RDLC: abcd efgh ijklmnop -or- abcd efgh ijklmnop (are your only options)

This is because RDLC is using a earlier namespace/formatting from 2005, while RDL is using 2008. This however will change with VS2010

Since chrome has come up with the multiple profiles you will not get it directly in C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions but you have to first type chrome://version/ in a tab and then look out for Profile path inside that and after you reach to your profile path look for Extensions folder in it and then folder with the desired extension Id

To get the maximum value of a column across a set of rows:

SELECT MAX(column1) FROM table; -- expect one result

To get the maximum value of a set of columns, literals, or variables for each row:

SELECT GREATEST(column1, 1, 0, @val) FROM table; -- expect many results

@curt is correct, but I've noticed that sometimes even this fails with NULL disallowed errors, and it seems to be intermittent. I avoided the error at all times, by also setting the Indenty Seed to 1 and IDENTITY(1, 1) NOT FOR REPLICATION.

$(form).ajaxSubmit();

Following example uses InputBox method to validate user entry to unhide sheets: Important thing here is to use wrap InputBox variable inside StrPtr so it could be compared to '0' when user chose to click 'x' icon on the InputBox.

Sub unhidesheet()

Dim ws As Worksheet
Dim pw As String

pw = InputBox("Enter Password to Unhide Sheets:", "Unhide Data Sheets")
If StrPtr(pw) = 0 Then

   Exit Sub
ElseIf pw = NullString Then
   Exit Sub
ElseIf pw = 123456 Then
    For Each ws In ThisWorkbook.Worksheets
        ws.Visible = xlSheetVisible
    Next
End If
End Sub

Go to File-> Project Structure-> Libraries and click green "+" to add the directory folder that has the JARs to CLASSPATH. Everything in that folder will be added to CLASSPATH.

Update:

It's 2018. It's a better idea to use a dependency manager like Maven and externalize your dependencies. Don't add JAR files to your project in a /lib folder anymore.

Suppose your DF is having those extra character in between numbers as well.The last entry.

  result   time
0   +52A  09:00
1   +62B  10:00
2   +44a  11:00
3   +30b  12:00
4  -110a  13:00
5   3+b0  14:00

You can try str.replace to remove characters not only from start and end but also from in between.

DF['result'] = DF['result'].str.replace('\+|a|b|\-|A|B', '')

Output:

  result   time
0     52  09:00
1     62  10:00
2     44  11:00
3     30  12:00
4    110  13:00
5     30  14:00

they are two different things..

[] is declaring an Array:
given, a list of elements held by numeric index.

{} is declaring a new object:
given, an object with fields with Names and type+value,
some like to think of it as "Associative Array". but are not arrays, in their representation.

you can declare time in two ways for this problem..

1) either give too long time that your file reading is complete in between that time.

<session-config>
    <session-timeout> 1000 </session-timeout>
</session-config>

2)declare time which is never expires your session.

<session-config>
    <session-timeout>-1</session-timeout>
</session-config>

Use double braces {{ or }} so your code becomes:

sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}", 
prop.Type, prop.Name));

// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

Just define a getter.

class MyClass
{
  get MY_CONST () { return 'string'; }

  constructor ()
  {
    console.log ("MyClass MY_CONST:", this.MY_CONST);
  }
}

var obj = new MyClass();

As @page with pagenumbers don't work in browsers for now I was looking for alternatives.
I've found an answer posted by Oliver Kohll.
I'll repost it here so everyone could find it more easily:
For this answer we are not using @page, which is a pure CSS answer, but work in FireFox 20+ versions. Here is the link of an example.
The CSS is:

#content {
    display: table;
}

#pageFooter {
    display: table-footer-group;
}

#pageFooter:after {
    counter-increment: page;
    content: counter(page);
}

And the HTML code is:

<div id="content">
  <div id="pageFooter">Page </div>
  multi-page content here...
</div>

This way you can customize your page number by editing parametrs to #pageFooter. My example:

#pageFooter:after {
    counter-increment: page;
    content:"Page " counter(page);
    left: 0; 
    top: 100%;
    white-space: nowrap; 
    z-index: 20;
    -moz-border-radius: 5px; 
    -moz-box-shadow: 0px 0px 4px #222;  
    background-image: -moz-linear-gradient(top, #eeeeee, #cccccc);  
  }

This trick worked for me fine. Hope it will help you.

The simple way to open the link in a new tab is to add a target attribute in the link having a value equals to "_blanl", like this :

<a href="http://www.WEBSITE_NAME.com" target="_blank"></a>

MDN suggests that there's a much cleaner way of doing this in modern browsers:

// Assuming we're listening for e.g. a 'change' event on `element`

// Create a new 'change' event
var event = new Event('change');

// Dispatch it.
element.dispatchEvent(event);

In very short - in MVC Controler is aware of (controls) view, while in MVVM, ViewModel is unaware of who consumes it. ViewModel exposes its observable properties and actions to whoever might be interested in using it. That fact makes testing easier since there is no reference to UI within ViewModel.

Update by Arkadiy: I've observed more correct behavior of System.currentTimeMillis() on Windows 7 in Oracle Java 8. The time was returned with 1 millisecond precision. The source code in OpenJDK has not changed, so I do not know what causes the better behavior.

David Holmes of Sun posted a blog article a couple years ago that has a very detailed look at the Java timing APIs (in particular System.currentTimeMillis() and System.nanoTime()), when you would want to use which, and how they work internally.

Inside the Hotspot VM: Clocks, Timers and Scheduling Events - Part I - Windows

One very interesting aspect of the timer used by Java on Windows for APIs that have a timed wait parameter is that the resolution of the timer can change depending on what other API calls may have been made - system wide (not just in the particular process). He shows an example where using Thread.sleep() will cause this resolution change.

My solution was to use a short nickname (less than 31 characters) and then write the entire name in cell 0.

You can also use a function within stat_summary to calculate the mean and the hjust argument to place the text, you need a additional function but no additional data frame:

fun_mean <- function(x){
  return(data.frame(y=mean(x),label=mean(x,na.rm=T)))}


ggplot(PlantGrowth,aes(x=group,y=weight)) +
geom_boxplot(aes(fill=group)) +
stat_summary(fun.y = mean, geom="point",colour="darkred", size=3) +
stat_summary(fun.data = fun_mean, geom="text", vjust=-0.7)

Here's how its done: ParentClass.prototype.myMethod();

Or if you want to call it in the context of the current instance, you can do: ParentClass.prototype.myMethod.call(this)

Same goes for calling a parent method from child class with arguments: ParentClass.prototype.myMethod.call(this, arg1, arg2, ..) * Hint: use apply() instead of call() to pass arguments as an array.

Here's a fixed version of it: http://play.golang.org/p/w2ZcOzGHKR

The biggest fix that was needed is when Unmarshalling an array, that property needs to be an array/slice in the struct as well.

For example:

{ "things": ["a", "b", "c"] }

Would Unmarshal into a:

type Item struct {
    Things []string
}

And not into:

type Item struct {
    Things string
}

The other thing to watch out for when Unmarshaling is that the types line up exactly. It will fail when Unmarshalling a JSON string representation of a number into an int or float field -- "1" needs to Unmarshal into a string, not into an int like we saw with ShippingAdditionalCost int

This answer says to use

mapfile -t myArray < file.txt

I made a shim for mapfile if you want to use mapfile on bash < 4.x for whatever reason. It uses the existing mapfile command if you are on bash >= 4.x

Currently, only options -d and -t work. But that should be enough for that command above. I've only tested on macOS. On macOS Sierra 10.12.6, the system bash is 3.2.57(1)-release. So the shim can come in handy. You can also just update your bash with homebrew, build bash yourself, etc.

It uses this technique to set variables up one call stack.

You could do it with jsoup http://jsoup.org/

Whitelist whitelist = Whitelist.none();
String cleanStr = Jsoup.clean(yourText, whitelist);

You need to create own PCH file
Add New file -> Other-> PCH file

Then add the path of this PCH file to your build setting->prefix header->path

($(SRCROOT)/filename.pch)

SELECT MONTHNAME(t.summaryDateTime) as month, YEAR(t.summaryDateTime) as year
FROM trading_summary t
GROUP BY YEAR(t.summaryDateTime) DESC, MONTH(t.summaryDateTime) DESC

Should use DESC for both YEAR and Month to get correct order.

Yes it is valid according to xhtml1-strict.dtd. The following XHTML passes the validation:

Here a solution if you want an empty data frame with a defined number of rows and NO columns:

df = data.frame(matrix(NA, ncol=1, nrow=10)[-1]

I had to add allowFullScreen attribute to the "parent" iframe. The case of the attribute does matter. I don't think Firefox or Edge/IE11 has a browser specific allowFullScreen attribute. So it looks something like this:

<iframe allowFullScreen='allowFullScreen' src='http://api.youtube.com/...'/>

Just to add one more point to this:

R does have a data structure equivalent to the Python dict in the hash package. You can read about it in this blog post from the Open Data Group. Here's a simple example:

> library(hash)
> h <- hash( keys=c('foo','bar','baz'), values=1:3 )
> h[c('foo','bar')]
<hash> containing 2 key-value pairs.
  bar : 2
  foo : 1

In terms of usability, the hash class is very similar to a list. But the performance is better for large datasets.

Just type

gcc --version

in any terminal near you.. ;-)

Yep, just use the trailing slash to recursively pull the directory. Works for me with Nexus 5 and current version of adb (March 2014).

connection = DriverManager.getConnection("jdbc:sqlite:D:\\testdb.db");

Instead of this put

connection = DriverManager.getConnection("jdbc:sqlite:D:\\testdb");

Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.

If the purpose of the CSS class on the <form/> element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/> element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

Daniel pointed me to correct way. I used it like this-

float scaleFactor = 0.8f;

UISegmentedControl *segmentedControl = [[UISegmentedControl alloc]
initWithFrame:CGRectMake(10, 70, 300/scaleFactor,35)];

[segmentedControl insertSegmentWithTitle:@"..." atIndex:0 animated:NO];
[segmentedControl insertSegmentWithTitle:@"..." atIndex:1 animated:NO];
[segmentedControl insertSegmentWithTitle:@"..." atIndex:2 animated:NO];

segmentedControl.transform = CGAffineTransformMakeScale(scaleFactor, 1);
CGPoint segmentedControlCenter = segmentedControl.center;
segmentedControlCenter.x = self.center.x;
segmentedControl.center = segmentedControlCenter;

Somewhat convoluted, but:

Select * from myTable m
join (SELECT a.COLUMN_VALUE || b.COLUMN_VALUE status
FROM   (TABLE(Sys.Dbms_Debug_Vc2coll('Done', 'Finished except', 'In Progress'))) a
JOIN (Select '%' COLUMN_VALUE from dual) b on 1=1) params
on params.status like m.status;

This was a solution for a very unique problem, but it might help someone. Essentially there is no "in like" statement and there was no way to get an index for the first variable_n characters of the column, so I made this to make a fast dynamic "in like" for use in SSRS.

The list content ('Done', 'Finished except', 'In Progress') can be variable.

Increase the height i.e.. android:height="Some size" , it is working fine for me.

Java code:

Pattern pattern1 = Pattern.compile("(\\_\\(.*?\\))");
System.out.println(fileName.replace(matcher1.group(1), ""));

You could create a Automator workflow with a single step - "Run Shell Script"

Then File > Save As, and change the File Format to "Application". When you open the application, it will run the Shell Script step, executing the command, exiting after it completes.

The benefit to this is it's really simple to do, and you can very easily get user input (say, selecting a bunch of files), then pass it to the input of the shell script (either to stdin, or as arguments).

(Automator is in your /Applications folder!)

What are named tuples?

A named tuple is a tuple.

It does everything a tuple can.

But it's more than just a tuple.

It's a specific subclass of a tuple that is programmatically created to your specification, with named fields and a fixed length.

This, for example, creates a subclass of tuple, and aside from being of fixed length (in this case, three), it can be used everywhere a tuple is used without breaking. This is known as Liskov substitutability.

New in Python 3.6, we can use a class definition with typing.NamedTuple to create a namedtuple:

from typing import NamedTuple

class ANamedTuple(NamedTuple):
    """a docstring"""
    foo: int
    bar: str
    baz: list

The above is the same as the below, except the above additionally has type annotations and a docstring. The below is available in Python 2+:

>>> from collections import namedtuple
>>> class_name = 'ANamedTuple'
>>> fields = 'foo bar baz'
>>> ANamedTuple = namedtuple(class_name, fields)

This instantiates it:

>>> ant = ANamedTuple(1, 'bar', [])

We can inspect it and use its attributes:

>>> ant
ANamedTuple(foo=1, bar='bar', baz=[])
>>> ant.foo
1
>>> ant.bar
'bar'
>>> ant.baz.append('anything')
>>> ant.baz
['anything']

Deeper explanation

To understand named tuples, you first need to know what a tuple is. A tuple is essentially an immutable (can't be changed in-place in memory) list.

Here's how you might use a regular tuple:

>>> student_tuple = 'Lisa', 'Simpson', 'A'
>>> student_tuple
('Lisa', 'Simpson', 'A')
>>> student_tuple[0]
'Lisa'
>>> student_tuple[1]
'Simpson'
>>> student_tuple[2]
'A'

You can expand a tuple with iterable unpacking:

>>> first, last, grade = student_tuple
>>> first
'Lisa'
>>> last
'Simpson'
>>> grade
'A'

Named tuples are tuples that allow their elements to be accessed by name instead of just index!

You make a namedtuple like this:

>>> from collections import namedtuple
>>> Student = namedtuple('Student', ['first', 'last', 'grade'])

You can also use a single string with the names separated by spaces, a slightly more readable use of the API:

>>> Student = namedtuple('Student', 'first last grade')

How to use them?

You can do everything tuples can do (see above) as well as do the following:

>>> named_student_tuple = Student('Lisa', 'Simpson', 'A')
>>> named_student_tuple.first
'Lisa'
>>> named_student_tuple.last
'Simpson'
>>> named_student_tuple.grade
'A'
>>> named_student_tuple._asdict()
OrderedDict([('first', 'Lisa'), ('last', 'Simpson'), ('grade', 'A')])
>>> vars(named_student_tuple)
OrderedDict([('first', 'Lisa'), ('last', 'Simpson'), ('grade', 'A')])
>>> new_named_student_tuple = named_student_tuple._replace(first='Bart', grade='C')
>>> new_named_student_tuple
Student(first='Bart', last='Simpson', grade='C')

A commenter asked:

In a large script or programme, where does one usually define a named tuple?

The types you create with namedtuple are basically classes you can create with easy shorthand. Treat them like classes. Define them on the module level, so that pickle and other users can find them.

The working example, on the global module level:

>>> from collections import namedtuple
>>> NT = namedtuple('NT', 'foo bar')
>>> nt = NT('foo', 'bar')
>>> import pickle
>>> pickle.loads(pickle.dumps(nt))
NT(foo='foo', bar='bar')

And this demonstrates the failure to lookup the definition:

>>> def foo():
...     LocalNT = namedtuple('LocalNT', 'foo bar')
...     return LocalNT('foo', 'bar')
... 
>>> pickle.loads(pickle.dumps(foo()))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
_pickle.PicklingError: Can't pickle <class '__main__.LocalNT'>: attribute lookup LocalNT on __main__ failed

Why/when should I use named tuples instead of normal tuples?

Use them when it improves your code to have the semantics of tuple elements expressed in your code.

You can use them instead of an object if you would otherwise use an object with unchanging data attributes and no functionality.

You can also subclass them to add functionality, for example:

class Point(namedtuple('Point', 'x y')):
    """adding functionality to a named tuple"""
        __slots__ = ()
        @property
        def hypot(self):
            return (self.x ** 2 + self.y ** 2) ** 0.5
        def __str__(self):
            return 'Point: x=%6.3f  y=%6.3f  hypot=%6.3f' % (self.x, self.y, self.hypot)

Why/when should I use normal tuples instead of named tuples?

It would probably be a regression to switch from using named tuples to tuples. The upfront design decision centers around whether the cost from the extra code involved is worth the improved readability when the tuple is used.

There is no extra memory used by named tuples versus tuples.

Is there any kind of "named list" (a mutable version of the named tuple)?

You're looking for either a slotted object that implements all of the functionality of a statically sized list or a subclassed list that works like a named tuple (and that somehow blocks the list from changing in size.)

A now expanded, and perhaps even Liskov substitutable, example of the first:

from collections import Sequence

class MutableTuple(Sequence): 
    """Abstract Base Class for objects that work like mutable
    namedtuples. Subclass and define your named fields with 
    __slots__ and away you go.
    """
    __slots__ = ()
    def __init__(self, *args):
        for slot, arg in zip(self.__slots__, args):
            setattr(self, slot, arg)
    def __repr__(self):
        return type(self).__name__ + repr(tuple(self))
    # more direct __iter__ than Sequence's
    def __iter__(self): 
        for name in self.__slots__:
            yield getattr(self, name)
    # Sequence requires __getitem__ & __len__:
    def __getitem__(self, index):
        return getattr(self, self.__slots__[index])
    def __len__(self):
        return len(self.__slots__)

And to use, just subclass and define __slots__:

class Student(MutableTuple):
    __slots__ = 'first', 'last', 'grade' # customize 


>>> student = Student('Lisa', 'Simpson', 'A')
>>> student
Student('Lisa', 'Simpson', 'A')
>>> first, last, grade = student
>>> first
'Lisa'
>>> last
'Simpson'
>>> grade
'A'
>>> student[0]
'Lisa'
>>> student[2]
'A'
>>> len(student)
3
>>> 'Lisa' in student
True
>>> 'Bart' in student
False
>>> student.first = 'Bart'
>>> for i in student: print(i)
... 
Bart
Simpson
A

for image write this

<input type=file accept="image/*">

For other, You can use the accept attribute on your form to suggest to the browser to restrict certain types. However, you'll want to re-validate in your server-side code to make sure. Never trust what the client sends you

Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:

LIVE DEMO

<div class="circle"></div>

CSS:

.circle, .circle:before{
  position:absolute;
  border-radius:150px;  
}
.circle{  
  width:200px;
  height:200px;
  z-index:0;
  margin:11%;
  padding:40px;
  background: hsla(0, 100%, 100%, 0.6);   
}
.circle:before{
  content:'';
  display:block;
  z-index:-1;  
  width:200px;
  height:200px;

  padding:44px;
  border: 6px solid hsla(0, 100%, 100%, 0.6);
  /* 4px more padding + 6px border = 10 so... */  
  top:-10px;
  left:-10px; 
}

The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.

In Python 3 and Python 2.7+, dictionary comprehensions look like the below:

d = {k:v for k, v in iterable}

For Python 2.6 or earlier, see fortran's answer.

Give this a try:

success: function(json) {
   console.log(JSON.stringify(json.topics));
   $.each(json.topics, function(idx, topic){
     $("#nav").html('<a href="' + topic.link_src + '">' + topic.link_text + "</a>");
   });
},

 import java.util.Scanner;
    public class Print {
        public static void main(String[] args) {
            int row,temp,c,n;
            Scanner s=new Scanner(System.in);
            n=s.nextInt();
            temp = n;
            for ( row = 1 ; row <= n ; row++ )
               {
                  for ( c = 1 ; c < temp ; c++ )
                    System.out.print(" ");

                  temp--;

                  for ( c = 1 ; c <= 2*row - 1 ; c++ )
                      System.out.print("*");

                  System.out.println("");
               }
        }

    }

I had the exact same problem in a project. The issue is that even though the fetch size might be small enough, the JDBCTemplate reads all the result of your query and maps it out in a huge list which might blow your memory. I ended up extending NamedParameterJdbcTemplate to create a function which returns a Stream of Object. That Stream is based on the ResultSet normally returned by JDBC but will pull data from the ResultSet only as the Stream requires it. This will work if you don't keep a reference of all the Object this Stream spits. I did inspire myself a lot on the implementation of org.springframework.jdbc.core.JdbcTemplate#execute(org.springframework.jdbc.core.ConnectionCallback). The only real difference has to do with what to do with the ResultSet. I ended up writing this function to wrap up the ResultSet:

private <T> Stream<T> wrapIntoStream(ResultSet rs, RowMapper<T> mapper) {
    CustomSpliterator<T> spliterator = new CustomSpliterator<T>(rs, mapper, Long.MAX_VALUE, NON-NULL | IMMUTABLE | ORDERED);
    Stream<T> stream = StreamSupport.stream(spliterator, false);
    return stream;
}
private static class CustomSpliterator<T> extends Spliterators.AbstractSpliterator<T> {
    // won't put code for constructor or properties here
    // the idea is to pull for the ResultSet and set into the Stream
    @Override
    public boolean tryAdvance(Consumer<? super T> action) {
        try {
            // you can add some logic to close the stream/Resultset automatically
            if(rs.next()) {
                T mapped = mapper.mapRow(rs, rowNumber++);
                action.accept(mapped);
                return true;
            } else {
                return false;
            }
        } catch (SQLException) {
            // do something with this Exception
        }
    }
}

you can add some logic to make that Stream "auto closable", otherwise don't forget to close it when you are done.

I tried as shown in the first answer. It works, but minus brought me into confusion. My answer by Groovy:

import static java.util.concurrent.TimeUnit.*

...

private static String formatElapsedTime(long millis) {

    int hrs = MILLISECONDS.toHours(millis) % 24
    int min = MILLISECONDS.toMinutes(millis) % 60
    int sec = MILLISECONDS.toSeconds(millis) % 60
    int mls = millis % 1000

    sprintf( '%02d:%02d:%02d (%03d)', [hrs, min, sec, mls])
}

If you wish to create a pdf from php, pdflib will help you (as some others suggested).

Else, if you want to convert an HTML page to PDF via PHP, you'll find a little trouble outta here.. For 3 years I've been trying to do it as best as I can.

So, the options I know are:

DOMPDF : php class that wraps the html and builds the pdf. Works good, customizable (if you know php), based on pdflib, if I remember right it takes even some CSS. Bad news: slow when the html is big or complex.

HTML2PS: same as DOMPDF, but this one converts first to a .ps (ghostscript) file, then, to whatever format you need (pdf, jpg, png). For me is little better than dompdf, but has the same speed problem.. but, better compatibility with CSS.

Those two are php classes, but if you can install some software on the server, and access it throught passthru() or system(), give a look to these too:

wkhtmltopdf: based on webkit (safari's wrapper), is really fast and powerful.. seems like this is the best one (atm) for converting html pages to pdf on the fly; taking only 2 seconds for a 3 page xHTML document with CSS2. It is a recent project, anyway, the google.code page is often updated.

htmldoc : This one is a tank, it never really stops/crashes.. the project looks dead since 2007, but anyway if you don't need CSS compatibility this can be nice for you.

If your goal is to simply display some static files you can use the Connect package. I have had some success (I'm still pretty new to NodeJS myself), using it and the twitter bootstrap API in combination.

at the command line

:\> cd <path you wish your server to reside>
:\> npm install connect

Then in a file (I named) Server.js

var connect = require('connect'),
   http = require('http');
connect()
   .use(connect.static('<pathyouwishtoserve>'))
   .use(connect.directory('<pathyouwishtoserve>'))
   .listen(8080);

Finally

:\>node Server.js

Caveats:

If you don't want to display the directory contents, exclude the .use(connect.directory line.

So I created a folder called "server" placed index.html in the folder and the bootstrap API in the same folder. Then when you access the computers IP:8080 it's automagically going to use the index.html file.

If you want to use port 80 (so just going to http://, and you don't have to type in :8080 or some other port). you'll need to start node with sudo, I'm not sure of the security implications but if you're just using it for an internal network, I don't personally think it's a big deal. Exposing to the outside world is another story.

Update 1/28/2014:

I haven't had to do the following on my latest versions of things, so try it out like above first, if it doesn't work (and you read the errors complaining it can't find nodejs), go ahead and possibly try the below.

End Update

Additionally when running in ubuntu I ran into a problem using nodejs as the name (with NPM), if you're having this problem, I recommend using an alias or something to "rename" nodejs to node.

Commands I used (for better or worse):

Create a new file called node

:\>gedit /usr/local/bin/node
#!/bin/bash
exec /nodejs "$@"

sudo chmod -x /usr/local/bin/node

That ought to make

node Server.js 

work just fine

InputStream is;

try {
    is = new FileInputStream("c://filename");

    is.close(); 
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

return is;

Just use strftime :)

Something like that:

my_date = datetime.datetime(2013, 1, 7, 10, 31, 34, 243366, tzinfo=<UTC>)
print(my_date.strftime("%Y, %d %B"))

After edited your question to format timedelta, you could use:

def timedelta_tuple(timedelta_object):
   return timedelta_object.days, timedelta_object.seconds//3600, (timedelta_object.seconds//60)%60

To achieve this you can use:

strcpy(string, "");

for $d in $doc/element2/element3 return fn:string-join(fn:data($d/element()), ".").
$doc stores the Xml.

Unique key :- It should be used when you have to give unique value.In the case of unique key it means null values are also allowed.Unique keys are those keys which are unique and non similar in that column like for example your pet name.it can be nothing like null and if you are asking in context of database then it must be noted that every null is different from another null in the database.EXCEPT-SQL Server where null=null is true

primary key :- It should be used when you have to give uniquely identify a row.primary is key which unique for every row in a database constraint is that it doesn't allow null in it.so, you might have seen that the database have a column which is auto increment and it is the primary key of the table. plus it can be used as a foreign key in another table.example can be orderId on a order Table,billId in a bill Table.

now coming back to situation when to use it:-

1) primary key in the column which can not be null in the table and you are using as foreign key in another table for creating relationship

2) unique key in table where it doesn't affect in table or in the whole database whether you take the null for the particular column like snacks in the restaurant it is possible you don't take snacks in a restaurant

For MacOs & Unix

Just by adding sudo to command will work, as it would run it as a superuser.

sudo pip install --upgrade pip

It is advised that you should not directly do it though - please see this post

Open Terminal and execute commands given below.

cd /etc
subl bashrc

subl denotes Sublime editor. You can replace subl with vi to open bashrc file in default editor. This will workout only if you have bashrc file, created earlier.

You can also use the non-standard IE-only css attribute writing-mode

div.page    { 
   writing-mode: tb-rl;
}

Do you checks that file is uploaded ok ? Maybe you exceeded max_post_size, or max_upload_filesize. When login using FileZilla you are copying files as you, when uploading by PHP wiritng this file is from user that runs apache (for exaplme www-data), try to put chmod 755 for images.

IP can be any LAN or WAN IP address. But you'll want to set your firewall connection allow it.

Device connection with webserver pc can be by LAN or WAN (i.e by wifi, connectify, adhoc, cable, mypublic wifi etc)

You should follow these steps:

1. Go to the control panel
2. Inbound rules > new rules
3. Click port > next > specific local port > enter 8080 > next > allow the connection>
4. Next > tick all (domain, private, public) > specify any name
5. Now you can access your localhost by any device (laptop, mobile, desktop, etc).
6. Enter ip address in browser url as 123.23.xx.xx:8080 to access localhost by any device.

This IP will be of that device which has the web server.

On Python 3.7+ do this:

my_data = "whatever you want\nshould match this f"
subprocess.run(["grep", "f"], text=True, input=my_data)

and you'll probably want to add capture_output=True to get the output of running the command as a string.

On older versions of Python, replace text=True with universal_newlines=True:

subprocess.run(["grep", "f"], universal_newlines=True, input=my_data)

I would like to compliment Ram Narasimhans answer with some tips I found on an Excel blog

Non-uniformly distributed data can be plotted in excel in

• X Y (Scatter Plots)
• Linear plots with Date axis
  • These don't take time into account, only days.
  • This method is quite cumbersome as it requires translating your time units to days, months, or years.. then change the axis labels... Not Recommended

Just like Ram Narasimhan suggested, to have the points centered you will want the mid point but you don't need to move to a numeric format, you can stay in the time format.

1- Add the center point to your data series

+---------------+-------+------+
|    Time       | Time  | Freq |
+---------------+-------+------+
| 08:00 - 09:00 | 08:30 |  12  |
| 09:00 - 10:00 | 09:30 |  13  |
| 10:00 - 11:00 | 10:30 |  10  |
| 13:00 - 14:00 | 13:30 |   5  |
| 14:00 - 15:00 | 14:30 |  14  |
+---------------+-------+------+

2- Create a Scatter Plot

3- Excel allows you to specify time values for the axis options. Time values are a parts per 1 of a 24-hour day. Therefore if we want to 08:00 to 15:00, then we Set the Axis options to:

• Minimum : Fix : 0.33333
• Maximum : Fix : 0.625
• Major unit : Fix : 0.041667

Alternative Display:

Make the points turn into columns:

To be able to represent these points as bars instead of just point we need to draw disjoint lines. Here is a way to go about getting this type of chart.

1- You're going to need to add several rows where we draw the line and disjoint the data

+-------+------+
| Time  | Freq |
+-------+------+
| 08:30 |   0  |
| 08:30 |  12  |
|       |      |
| 09:30 |   0  |
| 09:30 |  13  |
|       |      |
| 10:30 |   0  |
| 10:30 |  10  |
|       |      |
| 13:30 |   0  |
| 13:30 |   5  |
|       |      |

2- Plot an X Y (Scatter) Chart with Lines.

3- Now you can tweak the data series to have a fatter line, no markers, etc.. to get a bar/column type chart with non-uniformly distributed data.

But to make sure that your new row is accessible in the new table, you need to close the table:

DataTable destination = new DataTable(source.TableName);
destination = source.Clone();
DataRow sourceRow = source.Rows[0];
destination.ImportRow(sourceRow);

I did this

QDir path("/home/user/");
QStringList _dirs = path.entryList(QDir::Dirs);
std::cout << "_dirs_count = " << _dirs.count() << std::endl;
ui->cmbbox->addItem(Files);
ui->cmbbox->show();

You will see with this that the QStringList named _dirs is structured like an array whose members you can access via an index up to the value returned by _dirs.count()

All of this can be very confusing for an app developer that's simply using TLS to connect to their own web servers. Because ATS (App Transport Security) is becoming more important and we are encouraged to convert everything to https - I think more developers are going to encounter this issue.

My app simply exchanges data between our server and the user using the https protocol. Seeing the words "USES ENCRYPTION" in the disclaimers is a bit scary so I gave the US government office a call at their office and spoke to a representative of the Bureau of Industry and Security (BIS) http://www.bis.doc.gov/index.php/about-bis/contact-bis.

The representative asked me about my app and since it passed the "primary function test" in that it had nothing to do with security/communications and simply uses https as a channel for connecting my customer data to our servers - it fell in the EAR99 category which means it's exempt from getting government permission (see https://www.bis.doc.gov/index.php/licensing/commerce-control-list-classification/export-control-classification-number-eccn)

I hope this helps other app developers.

its as simple as:

$commaseparated_string = name,name2,name3,;
$result = rtrim($commaseparated_string,',');

Your Fundamentals are wrong, the program won't work, so go through the basics and rewrite the program.

Some of the corrections you must make are:

1) You must make a variable of semaphore type

sem_t semvar;

2) The functions sem_wait(), sem_post() require the semaphore variable but you are passing the semaphore id, which makes no sense.

sem_wait(&semvar);
   //your critical section code
sem_post(&semvar);

3) You are passing the semaphore to sem_wait() and sem_post() without initializing it. You must initialize it to 1 (in your case) before using it, or you will have a deadlock.

ret = semctl( semid, 1, SETVAL, sem);
if (ret == 1)
     perror("Semaphore failed to initialize");

Study the semaphore API's from the man page and go through this example.

From the Android docs (March 2016):

Before attempting to use this type of acceleration, you should first determine if your development system’s CPU supports one of the following virtualization extensions technologies:

• Intel Virtualization Technology (VT, VT-x, vmx) extensions
• AMD Virtualization (AMD-V, SVM) extensions (only supported for Linux)

The specifications from the manufacturer of your CPU should indicate if it supports virtualization extensions. If your CPU does not support one of these virtualization technologies, then you cannot use virtual machine acceleration.

Note: Virtualization extensions are typically enabled through your computer's BIOS and are frequently turned off by default. Check the documentation for your system's motherboard to find out how to enable virtualization extensions.

Most people talk about Genymotion being faster, and I have never heard anyone say it's slower. I definitely think it's faster, and it will be worth the ~20 minutes it will take to set up just to try it.
