I prefer to solve this in the classic way, creating a new array of my desired data type:

List<MyNewType> newArray = new ArrayList<>();
myOldArray.forEach(info -> newArray.add(objectMapper.convertValue(info, MyNewType.class)));

htmlStr is string then You need to Date and Time variables to string

while (reader.Read())
                {
                    DateTime Date = reader.GetDateTime(0);
                    DateTime Time = reader.GetDateTime(1);
                    htmlStr += "<tr><td>" + Date.ToString() + "</td><td>"  + 
                    Time.ToString() + "</td></tr>";                  
                }

If your entity is mapped through annotations, add the following code to your configuration;

configuration.addAnnotatedClass(theEntityPackage.EntityClassName.class);

For example;

configuration.addAnnotatedClass(com.foo.foo1.Products.class);

if your entity is mapped with xml file, use addClass instead of addAnnotatedClass.

As an example;

configuration.addClass(com.foo.foo1.Products.class);

Ping me if you need more help.

The other answers are generally correct and all outdated. Do use java.time, the modern Java date and time API, for your date and time work. With java.time your job has also become a lot easier compared to the situation when this question was asked in February 2014.

    String dateTimeString = "2014-01-16T10:25:00";
    LocalDateTime dateTime = LocalDateTime.parse(dateTimeString);
    LocalDateTime now = LocalDateTime.now(ZoneId.systemDefault());

    if (dateTime.isBefore(now)) {
        System.out.println(dateTimeString + " is in the past");
    } else if (dateTime.isAfter(now)) {
        System.out.println(dateTimeString + " is in the future");
    } else {
        System.out.println(dateTimeString + " is now");
    }

When running in 2020 output from this snippet is:

2014-01-16T10:25:00 is in the past

Since your string doesn’t inform of us any time zone or UTC offset, we need to know what was understood. The code above uses the device’ time zone setting. For a known time zone use like for example ZoneId.of("Asia/Ulaanbaatar"). For UTC specify ZoneOffset.UTC.

I am exploiting the fact that your string is in ISO 8601 format. The classes of java.time parse the most common ISO 8601 variants without us having to give any formatter.

Question: For Android development doesn’t java.time require Android API level 26?

java.time works nicely on both older and newer Android devices. It just requires at least Java 6.

• In Java 8 and later and on newer Android devices (from API level 26) the modern API comes built-in.
• In non-Android Java 6 and 7 get the ThreeTen Backport, the backport of the modern classes (ThreeTen for JSR 310; see the links at the bottom).
• On (older) Android use the Android edition of ThreeTen Backport. It’s called ThreeTenABP. And make sure you import the date and time classes from org.threeten.bp with subpackages.

• Java Specification Request (JSR) 310, where java.time was first described.
• ThreeTen Backport project, the backport of java.time to Java 6 and 7 (ThreeTen for JSR-310).

this worked:

    Date date = null;
    String dateStr = rs.getString("doc_date");
    if (dateStr != null) {
        date = dateFormat.parse(dateStr);
    }

using SimpleDateFormat.

For use datetime from input value, just set option useCurrent to false, and set in value the date

$('#datetimepicker1').datetimepicker({_x000D_
  useCurrent: false,_x000D_
  format: 'DD.MM.YYYY H:mm'_x000D_
});

If your $result variable is a string json like, you must use json_decode function to parse it as an object or array:

$result = '{"Cancelled":false,"MessageID":"402f481b-c420-481f-b129-7b2d8ce7cf0a","Queued":false,"SMSError":2,"SMSIncomingMessages":null,"Sent":false,"SentDateTime":"\/Date(-62135578800000-0500)\/"}';
$json = json_decode($result, true);
print_r($json);

OUTPUT

Array
(
    [Cancelled] => 
    [MessageID] => 402f481b-c420-481f-b129-7b2d8ce7cf0a
    [Queued] => 
    [SMSError] => 2
    [SMSIncomingMessages] => 
    [Sent] => 
    [SentDateTime] => /Date(-62135578800000-0500)/
)

Now you can work with $json variable as an array:

echo $json['MessageID'];
echo $json['SMSError'];
// other stuff

Always use EntityFunctions.TruncateTime() for both x.DateTimeStart and currentDate. such as :

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference).Where(x => EntityFunctions.TruncateTime(x.DateTimeStart) == EntityFunctions.TruncateTime(currentDate));

use your code within

  <script type="text/javascript">
     function window.onload()
       {

        var d = new Date()
        var gmtOffSet = -d.getTimezoneOffset();
        var gmtHours = Math.floor(gmtOffSet / 60);
        var GMTMin = Math.abs(gmtOffSet % 60);
        var dot = ".";
        var retVal = "" + gmtHours + dot + GMTMin;
       document.getElementById('<%= offSet.ClientID%>').value = retVal;

      }

Annotation-driven indicates to Spring that it should scan for annotated beans, and to not just rely on XML bean configuration. Component-scan indicates where to look for those beans.

Here's some doc: http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable

Add "[JsonIgnore]" to your model class

{
  public Customer()
  {
    Orders = new Collection<Order>();
  }

public int Id { get; set; }
public string Name { get; set; }
public string Surname { get; set; }

[JsonIgnore]
public ICollection<Order> Orders { get; set; }
}

try to use this java code :

Timestamp stamp = new Timestamp(System.currentTimeMillis());
Date date = new Date(stamp.getTime());
DateFormat f = new SimpleDateFormat("yyyy-MM-dd");
DateFormat f1 = new SimpleDateFormat("yyyy/MM/dd");
String d = f.format(date);
String d1 = f1.format(date);
System.out.println(d);
System.out.println(d1);

you could try

if (isValid) {
    document.getElementById("endTimeLabel").style.display = "none";
}else {
    document.getElementById("endTimeLabel").style.display = "block";
}

alone those lines

If all you want to do is display the date with a specific format, just call:

@String.Format(myFormat, Model.MyDateTime)

Using @Html.DisplayFor(...) is just extra work unless you are specifying a template, or need to use something that is built on templates, like iterating an IEnumerable<T>. Creating a template is simple enough, and can provide a lot of flexibility too. Create a folder in your views folder for the current controller (or shared views folder) called DisplayTemplates. Inside that folder, add a partial view with the model type you want to build the template for. In this case I added /Views/Shared/DisplayTemplates and added a partial view called ShortDateTime.cshtml.

@model System.DateTime

@Model.ToShortDateString()

And now you can call that template with the following line:

@Html.DisplayFor(m => m.MyDateTime, "ShortDateTime")

To catch the error message and its code:

UPDATE April, 16, 2019

As suggested by Diego Scaravaggi, for Postgres 9.2 and up, use GET STACKED DIAGNOSTICS:

do language plpgsql $$
declare
    v_state   TEXT;
    v_msg     TEXT;
    v_detail  TEXT;
    v_hint    TEXT;
    v_context TEXT;
begin

    create table yyy(a int);
    create table yyy(a int); -- this will cause an error

exception when others then 

    get stacked diagnostics
        v_state   = returned_sqlstate,
        v_msg     = message_text,
        v_detail  = pg_exception_detail,
        v_hint    = pg_exception_hint,
        v_context = pg_exception_context;

    raise notice E'Got exception:
        state  : %
        message: %
        detail : %
        hint   : %
        context: %', v_state, v_msg, v_detail, v_hint, v_context;

    raise notice E'Got exception:
        SQLSTATE: % 
        SQLERRM: %', SQLSTATE, SQLERRM;     

    raise notice '%', message_text; -- invalid. message_text is contextual to GET STACKED DIAGNOSTICS only

end; $$;

Result:

NOTICE:  Got exception:
        state  : 42P07
        message: relation "yyy" already exists
        detail : 
        hint   : 
        context: SQL statement "create table yyy(a int)"
PL/pgSQL function inline_code_block line 11 at SQL statement
NOTICE:  Got exception:
        SQLSTATE: 42P07 
        SQLERRM: relation "yyy" already exists

ERROR:  column "message_text" does not exist
LINE 1: SELECT message_text
               ^
QUERY:  SELECT message_text
CONTEXT:  PL/pgSQL function inline_code_block line 33 at RAISE
SQL state: 42703

Aside from GET STACKED DIAGNOSTICS is SQL standard-compliant, its diagnostics variables (e.g., message_text) are contextual to GSD only. So if you have a field named message_text in your table, there's no chance that GSD can interfere with your field's value.

Still no line number though.

Java 8 Native

java.time makes it simple since Java 8. And thread safe.

ZonedDateTime.now( ZoneOffset.UTC ).format( DateTimeFormatter.ISO_INSTANT )

Result: 2015-04-14T11:07:36.639Z

You may be tempted to use lighter Temporal such as Instant or LocalDateTime, but they lacks formatter support or time zone data. Only ZonedDateTime works out of the box.

By tuning or chaining the options / operations of ZonedDateTime and DateTimeFormatter, you can easily control the timezone and precision, to a certain degree:

ZonedDateTime.now( ZoneId.of( "Europe/Paris" ) )
             .truncatedTo( ChronoUnit.MINUTES )
             .format( DateTimeFormatter.ISO_DATE_TIME )

Result: 2015-04-14T11:07:00+01:00[Europe/Paris]

Refined requirements, such as removing the seconds part, must still be served by custom formats or custom post process.

.format( DateTimeFormatter.ISO_LOCAL_DATE_TIME ) // 2015-04-14T11:07:00
.format( DateTimeFormatter.ISO_LOCAL_DATE ) // 2015-04-14
.format( DateTimeFormatter.ISO_LOCAL_TIME ) // 11:07:00
.format( DateTimeFormatter.ofPattern( "yyyy-MM-dd HH:mm" ) ) // 2015-04-14 11:07

For Java 6 & 7, you may consider back-ports of java.time such as ThreeTen-Backport, which also has an Android port. Both are lighter than Joda, and has learned from Joda's experience - esp. considering that java.time is designed by Joda's author.

You can use the this customization to change the default mapping to java.util.Date

<xsd:annotation>
<xsd:appinfo>
    <jaxb:globalBindings>
        <jaxb:javaType name="java.util.Date" xmlType="xsd:dateTime"
                 parseMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.parseDateTime"
                 printMethod="org.apache.cxf.xjc.runtime.DataTypeAdapter.printDateTime"/>
    </jaxb:globalBindings>
</xsd:appinfo>

In Qt 4.7, there is the QDateTime::currentMSecsSinceEpoch() static function, which does exactly what you need, without any intermediary steps. Hence I'd recommend that for projects using Qt 4.7 or newer.

I was dealing with DateTimeOffset and unfortunately the "o" prints out "+0000" not "Z".

So I ended up with:

dateTimeOffset.UtcDateTime.ToString("o")

/\d+\.?\d*/

One or more digits (\d+), optional period (\.?), zero or more digits (\d*).

Depending on your usage or regex engine you may need to add start/end line anchors:

/^\d+\.?\d*$/

Debuggex Demo

Others have explained what NoneType is and a common way of ending up with it (i.e., failure to return a value from a function).

Another common reason you have None where you don't expect it is assignment of an in-place operation on a mutable object. For example:

mylist = mylist.sort()

The sort() method of a list sorts the list in-place, that is, mylist is modified. But the actual return value of the method is None and not the list sorted. So you've just assigned None to mylist. If you next try to do, say, mylist.append(1) Python will give you this error.

x^y is not "x to the power of y". It's "x XOR y".

This is for react-native, but login will work for all types.

isTokenExpired = async () => {
    try {
        const LoginTokenValue = await AsyncStorage.getItem('LoginTokenValue');
        if (JSON.parse(LoginTokenValue).RememberMe) {
            const { exp } = JwtDecode(LoginTokenValue);
            if (exp < (new Date().getTime() + 1) / 1000) {
                this.handleSetTimeout();
                return false;
            } else {
                //Navigate inside the application
                return true;
            }
        } else {
            //Navigate to the login page
        }
    } catch (err) {
        console.log('Spalsh -> isTokenExpired -> err', err);
        //Navigate to the login page
        return false;
    }
}

HTTP 2.0 is a binary protocol that multiplexes numerous streams going over a single (normally TLS-encrypted) TCP connection.

The contents of each stream are HTTP 1.1 requests and responses, just encoded and packed up differently. HTTP2 adds a number of features to manage the streams, but leaves old semantics untouched.

A small change to Paul's code so that it doesn't return the error mentioned above.

dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
           id.vars = "Species")
dat$x <- c(1:150, 1:150)
ggplot(aes(x = x, y = value, color = variable), data = dat) +  
  geom_point() + geom_line()

Below code will add listener for ENTER key on entire page.

This can be very useful in screens with single Action button eg Login, Register, Submit etc.

                if (e.which == 13 || event.keyCode == 13) {
                    alert('enter key is pressed');
                }
            });

You can make master point at 1258f0d0aae this way:

git checkout master
git reset --hard 1258f0d0aae

But you have to be careful about doing this. It may well rewrite the history of that branch. That would create problems if you have published it and other people are working on the branch.

Also, the git reset --hard command will throw away any uncommitted changes (i.e. those just in your working tree or the index).

You can also force an update to a branch with:

git branch -f master 1258f0d0aae

... but git won't let you do that if you're on master at the time.

On Ubuntu, You can follow these steps to resolve the issue:

1. Create a directory named plugins inside $HOME/.mozilla, if it doesn't exist already

2. Create a symlink to libnpjp2.so inside this directory using this command:

   ln -s $JAVA_HOME/jre/lib/i386/libnpjp2.so $MOZILLA_HOME/plugins
   

   -or-

   ln -s $JAVA_HOME/jre/lib/amd64/libnpjp2.so $MOZILLA_HOME/plugins
   

   depending on whether you're using a 32 or 64 bit JVM installation. Moreover, $JAVA_HOME is the location of your JVM installation.

More detailed instructions can be found here.

This simple(st) solution doesn't provide indentation, but it is nevertheless much easier on the human eye. Also it allows the xml to be handled more easily by simple tools like grep, head, awk, etc.

Use sed to replace '<' with itself preceeded with a newline.

And as mentioned by Gilles, it's probably not a good idea to use this in production.

# check you are getting more than one line out
sed 's/</\n</g' sample.xml | wc -l

# check the output looks generally ok
sed 's/</\n</g' sample.xml | head

# capture the pretty xml in a different file
sed 's/</\n</g' sample.xml > prettySample.xml

You can also do

t.index([:branch_id, :party_id], unique: true, name: 'by_branch_party')

as in the Ruby on Rails API.

Assuming your Car class has a getter method for price, you can simply use

System.out.println (car.get(i).getPrice());

where i is the index of the element.

You can also use

Car c = car.get(i);
System.out.println (c.getPrice());

You also need to return totalprice from your function if you need to store it

main

public static void processCar(ArrayList<Car> cars){
    int totalAmount=0;
    for (int i=0; i<cars.size(); i++){
        int totalprice= cars.get(i).computeCars ();
        totalAmount=+ totalprice; 
    }
}

And change the return type of your function

public int computeCars (){
    int  totalprice= price+tax;
    System.out.println (name + "\t" +totalprice+"\t"+year );
    return  totalprice; 
 }

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

It is a horrible mistake but:

Be sure you have Web.config files in your View at Remote. Maybe you skipped to upload it by your Ftp programme's filters.

Just see /etc/php5/php-fpm.conf pid = /var/run/php5-fpm.pid IS PID file

In file /etc/php5/fpm/pool.d/www.conf

listen = /var/run/php5-fpm.sock IS SOCKET file

if you pid equal listen (pid = /var/run/php5-fpm.sock and listen = /var/run/php5-fpm.sock) -> wrong settings and finish sett /etc/php5/fpm/pool.d/www.conf

user = nginx
group = nginx
listen.owner = nginx
listen.group = nginx
listen.mode = 0660

Always returning POSITION_NONE is simple but a little inefficient way because that evoke instantiation of all page that have already instantiated.

I've created a library ArrayPagerAdapter to change items in PagerAdapters dynamically.

Internally, this library's adapters return POSITION_NONE on getItemPosiition() only when necessary.

You can change items dynamically like following by using this library.

@Override
protected void onCreate(Bundle savedInstanceState) {
        /** ... **/
    adapter = new MyStatePagerAdapter(getSupportFragmentManager()
                            , new String[]{"1", "2", "3"});
    ((ViewPager)findViewById(R.id.view_pager)).setAdapter(adapter);
     adapter.add("4");
     adapter.remove(0);
}

class MyPagerAdapter extends ArrayViewPagerAdapter<String> {

    public MyPagerAdapter(String[] data) {
        super(data);
    }

    @Override
    public View getView(LayoutInflater inflater, ViewGroup container, String item, int position) {
        View v = inflater.inflate(R.layout.item_page, container, false);
        ((TextView) v.findViewById(R.id.item_txt)).setText(item);
        return v;
    }
}

Thils library also support pages created by Fragments.

Cross-Origin Read Blocking (CORB), an algorithm by which dubious cross-origin resource loads may be identified and blocked by web browsers before they reach the web page..It is designed to prevent the browser from delivering certain cross-origin network responses to a web page.

First Make sure these resources are served with a correct "Content-Type", i.e, for JSON MIME type - "text/json", "application/json", HTML MIME type - "text/html".

Second: set mode to cors i.e, mode:cors

The fetch would look something like this

 fetch("https://example.com/api/request", {
            method: 'POST',
            body: JSON.stringify(data),
            mode: 'cors',
            headers: {
                'Content-Type': 'application/json',
                "Accept": 'application/json',
            }
        })
    .then((data) => data.json())
    .then((resp) => console.log(resp))
    .catch((err) => console.log(err))

You will need to use different IP addresses. The server, whether Apache or IIS, grabs the traffic based on the IP and Port, which ever they are bound to listen to. Once it starts listening, then it uses the headers, such as the server name to filter and determine what site is being accessed. You can't do it will simply changing the server name in the request

Move your compiled native library files to $HADOOP_HOME/lib folder.

Then set your environment variables by editing .bashrc file

export HADOOP_COMMON_LIB_NATIVE_DIR=$HADOOP_HOME/lib  
export HADOOP_OPTS="$HADOOP_OPTS -Djava.library.path=$HADOOP_HOME/lib"

Make sure your compiled native library files are in $HADOOP_HOME/lib folder.

it should work.

Try:

        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

I'm developing an UWP application which connects to a MQTT broker in the LAN. I go a similar error.

MQTTnet.Exceptions.MqttCommunicationException: 'An attempt was made to access a socket in a way forbidden by its access permissions [::ffff:xxx.xxx.xxx.xxx]:1883'

ExtendedSocketException: An attempt was made to access a socket in a way forbidden by its access permissions [::ffff:xxx.xxx.xxx.xxx]:1883

Turned out that I forgot to give the app the correct capabilites ...

Introduction

Since it is not really clear from your question what exactly you are having trouble with, I wrote up this quick walkthrough about how to implement this feature; if you still have questions feel free to ask.

I have a working example of everything I am talking about here in this GitHub Repository.
If you want to know more about the example project visit the project homepage.

In any case the result should looks something like this:

If you first want to play around with the demo app you can install it from the Play Store:

Anyway lets get started.

Setting up the SearchView

In the folder res/menu create a new file called main_menu.xml. In it add an item and set the actionViewClass to android.support.v7.widget.SearchView. Since you are using the support library you have to use the namespace of the support library to set the actionViewClass attribute. Your xml file should look something like this:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto">

    <item android:id="@+id/action_search"
          android:title="@string/action_search"
          app:actionViewClass="android.support.v7.widget.SearchView"
          app:showAsAction="always"/>

</menu>

In your Fragment or Activity you have to inflate this menu xml like usual, then you can look for the MenuItem which contains the SearchView and implement the OnQueryTextListener which we are going to use to listen for changes to the text entered into the SearchView:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);

    final MenuItem searchItem = menu.findItem(R.id.action_search);
    final SearchView searchView = (SearchView) searchItem.getActionView();
    searchView.setOnQueryTextListener(this);

    return true;
}

@Override
public boolean onQueryTextChange(String query) {
    // Here is where we are going to implement the filter logic
    return false;
}

@Override
public boolean onQueryTextSubmit(String query) {
    return false;
}

And now the SearchView is ready to be used. We will implement the filter logic later on in onQueryTextChange() once we are finished implementing the Adapter.

Setting up the Adapter

First and foremost this is the model class I am going to use for this example:

public class ExampleModel {

    private final long mId;
    private final String mText;

    public ExampleModel(long id, String text) {
        mId = id;
        mText = text;
    }

    public long getId() {
        return mId;
    }

    public String getText() {
        return mText;
    }
}

It's just your basic model which will display a text in the RecyclerView. This is the layout I am going to use to display the text:

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <variable
            name="model"
            type="com.github.wrdlbrnft.searchablerecyclerviewdemo.ui.models.ExampleModel"/>

    </data>

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/selectableItemBackground"
        android:clickable="true">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="8dp"
            android:text="@{model.text}"/>

    </FrameLayout>

</layout>

As you can see I use Data Binding. If you have never worked with data binding before don't be discouraged! It's very simple and powerful, however I can't explain how it works in the scope of this answer.

This is the ViewHolder for the ExampleModel class:

public class ExampleViewHolder extends RecyclerView.ViewHolder {

    private final ItemExampleBinding mBinding;

    public ExampleViewHolder(ItemExampleBinding binding) {
        super(binding.getRoot());
        mBinding = binding;
    }

    public void bind(ExampleModel item) {
        mBinding.setModel(item);
    }
}

Again nothing special. It just uses data binding to bind the model class to this layout as we have defined in the layout xml above.

Now we can finally come to the really interesting part: Writing the Adapter. I am going to skip over the basic implementation of the Adapter and am instead going to concentrate on the parts which are relevant for this answer.

But first there is one thing we have to talk about: The SortedList class.

SortedList

The SortedList is a completely amazing tool which is part of the RecyclerView library. It takes care of notifying the Adapter about changes to the data set and does so it a very efficient way. The only thing it requires you to do is specify an order of the elements. You need to do that by implementing a compare() method which compares two elements in the SortedList just like a Comparator. But instead of sorting a List it is used to sort the items in the RecyclerView!

The SortedList interacts with the Adapter through a Callback class which you have to implement:

private final SortedList.Callback<ExampleModel> mCallback = new SortedList.Callback<ExampleModel>() {

    @Override
    public void onInserted(int position, int count) {
         mAdapter.notifyItemRangeInserted(position, count);
    }

    @Override
    public void onRemoved(int position, int count) {
        mAdapter.notifyItemRangeRemoved(position, count);
    }

    @Override
    public void onMoved(int fromPosition, int toPosition) {
        mAdapter.notifyItemMoved(fromPosition, toPosition);
    }

    @Override
    public void onChanged(int position, int count) {
        mAdapter.notifyItemRangeChanged(position, count);
    }

    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return mComparator.compare(a, b);
    }

    @Override
    public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
        return oldItem.equals(newItem);
    }

    @Override
    public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
        return item1.getId() == item2.getId();
    }
}

In the methods at the top of the callback like onMoved, onInserted, etc. you have to call the equivalent notify method of your Adapter. The three methods at the bottom compare, areContentsTheSame and areItemsTheSame you have to implement according to what kind of objects you want to display and in what order these objects should appear on the screen.

Let's go through these methods one by one:

@Override
public int compare(ExampleModel a, ExampleModel b) {
    return mComparator.compare(a, b);
}

This is the compare() method I talked about earlier. In this example I am just passing the call to a Comparator which compares the two models. If you want the items to appear in alphabetical order on the screen. This comparator might look like this:

private static final Comparator<ExampleModel> ALPHABETICAL_COMPARATOR = new Comparator<ExampleModel>() {
    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return a.getText().compareTo(b.getText());
    }
};

Now let's take a look at the next method:

@Override
public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
    return oldItem.equals(newItem);
}

The purpose of this method is to determine if the content of a model has changed. The SortedList uses this to determine if a change event needs to be invoked - in other words if the RecyclerView should crossfade the old and new version. If you model classes have a correct equals() and hashCode() implementation you can usually just implement it like above. If we add an equals() and hashCode() implementation to the ExampleModel class it should look something like this:

public class ExampleModel implements SortedListAdapter.ViewModel {

    private final long mId;
    private final String mText;

    public ExampleModel(long id, String text) {
        mId = id;
        mText = text;
    }

    public long getId() {
        return mId;
    }

    public String getText() {
        return mText;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;

        ExampleModel model = (ExampleModel) o;

        if (mId != model.mId) return false;
        return mText != null ? mText.equals(model.mText) : model.mText == null;

    }

    @Override
    public int hashCode() {
        int result = (int) (mId ^ (mId >>> 32));
        result = 31 * result + (mText != null ? mText.hashCode() : 0);
        return result;
    }
}

Quick side note: Most IDE's like Android Studio, IntelliJ and Eclipse have functionality to generate equals() and hashCode() implementations for you at the press of a button! So you don't have to implement them yourself. Look up on the internet how it works in your IDE!

Now let's take a look at the last method:

@Override
public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
    return item1.getId() == item2.getId();
}

The SortedList uses this method to check if two items refer to the same thing. In simplest terms (without explaining how the SortedList works) this is used to determine if an object is already contained in the List and if either an add, move or change animation needs to be played. If your models have an id you would usually compare just the id in this method. If they don't you need to figure out some other way to check this, but however you end up implementing this depends on your specific app. Usually it is the simplest option to give all models an id - that could for example be the primary key field if you are querying the data from a database.

With the SortedList.Callback correctly implemented we can create an instance of the SortedList:

final SortedList<ExampleModel> list = new SortedList<>(ExampleModel.class, mCallback);

As the first parameter in the constructor of the SortedList you need to pass the class of your models. The other parameter is just the SortedList.Callback we defined above.

Now let's get down to business: If we implement the Adapter with a SortedList it should look something like this:

public class ExampleAdapter extends RecyclerView.Adapter<ExampleViewHolder> {

    private final SortedList<ExampleModel> mSortedList = new SortedList<>(ExampleModel.class, new SortedList.Callback<ExampleModel>() {
        @Override
        public int compare(ExampleModel a, ExampleModel b) {
            return mComparator.compare(a, b);
        }

        @Override
        public void onInserted(int position, int count) {
            notifyItemRangeInserted(position, count);
        }

        @Override
        public void onRemoved(int position, int count) {
            notifyItemRangeRemoved(position, count);
        }

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

        @Override
        public void onChanged(int position, int count) {
            notifyItemRangeChanged(position, count);
        }

        @Override
        public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
            return oldItem.equals(newItem);
        }

        @Override
        public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
            return item1.getId() == item2.getId();
        }
    });

    private final LayoutInflater mInflater;
    private final Comparator<ExampleModel> mComparator;

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        mInflater = LayoutInflater.from(context);
        mComparator = comparator;
    }

    @Override
    public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(inflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    public void onBindViewHolder(ExampleViewHolder holder, int position) {
        final ExampleModel model = mSortedList.get(position);
        holder.bind(model);
    }

    @Override
    public int getItemCount() {
        return mSortedList.size();
    }
}

The Comparator used to sort the item is passed in through the constructor so we can use the same Adapter even if the items are supposed to be displayed in a different order.

Now we are almost done! But we first need a way to add or remove items to the Adapter. For this purpose we can add methods to the Adapter which allow us to add and remove items to the SortedList:

public void add(ExampleModel model) {
    mSortedList.add(model);
}

public void remove(ExampleModel model) {
    mSortedList.remove(model);
}

public void add(List<ExampleModel> models) {
    mSortedList.addAll(models);
}

public void remove(List<ExampleModel> models) {
    mSortedList.beginBatchedUpdates();
    for (ExampleModel model : models) {
        mSortedList.remove(model);
    }
    mSortedList.endBatchedUpdates();
}

We don't need to call any notify methods here because the SortedList already does this for through the SortedList.Callback! Aside from that the implementation of these methods is pretty straight forward with one exception: the remove method which removes a List of models. Since the SortedList has only one remove method which can remove a single object we need to loop over the list and remove the models one by one. Calling beginBatchedUpdates() at the beginning batches all the changes we are going to make to the SortedList together and improves performance. When we call endBatchedUpdates() the RecyclerView is notified about all the changes at once.

Additionally what you have to understand is that if you add an object to the SortedList and it is already in the SortedList it won't be added again. Instead the SortedList uses the areContentsTheSame() method to figure out if the object has changed - and if it has the item in the RecyclerView will be updated.

Anyway, what I usually prefer is one method which allows me to replace all items in the RecyclerView at once. Remove everything which is not in the List and add all items which are missing from the SortedList:

public void replaceAll(List<ExampleModel> models) {
    mSortedList.beginBatchedUpdates();
    for (int i = mSortedList.size() - 1; i >= 0; i--) {
        final ExampleModel model = mSortedList.get(i);
        if (!models.contains(model)) {
            mSortedList.remove(model);
        }
    }
    mSortedList.addAll(models);
    mSortedList.endBatchedUpdates();
}

This method again batches all updates together to increase performance. The first loop is in reverse since removing an item at the start would mess up the indexes of all items that come up after it and this can lead in some instances to problems like data inconsistencies. After that we just add the List to the SortedList using addAll() to add all items which are not already in the SortedList and - just like I described above - update all items that are already in the SortedList but have changed.

And with that the Adapter is complete. The whole thing should look something like this:

public class ExampleAdapter extends RecyclerView.Adapter<ExampleViewHolder> {

    private final SortedList<ExampleModel> mSortedList = new SortedList<>(ExampleModel.class, new SortedList.Callback<ExampleModel>() {
        @Override
        public int compare(ExampleModel a, ExampleModel b) {
            return mComparator.compare(a, b);
        }

        @Override
        public void onInserted(int position, int count) {
            notifyItemRangeInserted(position, count);
        }

        @Override
        public void onRemoved(int position, int count) {
            notifyItemRangeRemoved(position, count);
        }

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

        @Override
        public void onChanged(int position, int count) {
            notifyItemRangeChanged(position, count);
        }

        @Override
        public boolean areContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
            return oldItem.equals(newItem);
        }

        @Override
        public boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
            return item1 == item2;
        }
    });

    private final Comparator<ExampleModel> mComparator;
    private final LayoutInflater mInflater;

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        mInflater = LayoutInflater.from(context);
        mComparator = comparator;
    }

    @Override
    public ExampleViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(mInflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    public void onBindViewHolder(ExampleViewHolder holder, int position) {
        final ExampleModel model = mSortedList.get(position);
        holder.bind(model);
    }

    public void add(ExampleModel model) {
        mSortedList.add(model);
    }

    public void remove(ExampleModel model) {
        mSortedList.remove(model);
    }

    public void add(List<ExampleModel> models) {
        mSortedList.addAll(models);
    }

    public void remove(List<ExampleModel> models) {
        mSortedList.beginBatchedUpdates();
        for (ExampleModel model : models) {
            mSortedList.remove(model);
        }
        mSortedList.endBatchedUpdates();
    }

    public void replaceAll(List<ExampleModel> models) {
        mSortedList.beginBatchedUpdates();
        for (int i = mSortedList.size() - 1; i >= 0; i--) {
            final ExampleModel model = mSortedList.get(i);
            if (!models.contains(model)) {
                mSortedList.remove(model);
            }
        }
        mSortedList.addAll(models);
        mSortedList.endBatchedUpdates();
    }

    @Override
    public int getItemCount() {
        return mSortedList.size();
    }
}

The only thing missing now is to implement the filtering!

Implementing the filter logic

To implement the filter logic we first have to define a List of all possible models. For this example I create a List of ExampleModel instances from an array of movies:

private static final String[] MOVIES = new String[]{
        ...
};

private static final Comparator<ExampleModel> ALPHABETICAL_COMPARATOR = new Comparator<ExampleModel>() {
    @Override
    public int compare(ExampleModel a, ExampleModel b) {
        return a.getText().compareTo(b.getText());
    }
};

private ExampleAdapter mAdapter;
private List<ExampleModel> mModels;
private RecyclerView mRecyclerView;

    @Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);

    mAdapter = new ExampleAdapter(this, ALPHABETICAL_COMPARATOR);

    mBinding.recyclerView.setLayoutManager(new LinearLayoutManager(this));
    mBinding.recyclerView.setAdapter(mAdapter);

    mModels = new ArrayList<>();
    for (String movie : MOVIES) {
        mModels.add(new ExampleModel(movie));
    }
    mAdapter.add(mModels);
}

Nothing special going on here, we just instantiate the Adapter and set it to the RecyclerView. After that we create a List of models from the movie names in the MOVIES array. Then we add all the models to the SortedList.

Now we can go back to onQueryTextChange() which we defined earlier and start implementing the filter logic:

@Override
public boolean onQueryTextChange(String query) {
    final List<ExampleModel> filteredModelList = filter(mModels, query);
    mAdapter.replaceAll(filteredModelList);
    mBinding.recyclerView.scrollToPosition(0);
    return true;
}

This is again pretty straight forward. We call the method filter() and pass in the List of ExampleModels as well as the query string. We then call replaceAll() on the Adapter and pass in the filtered List returned by filter(). We also have to call scrollToPosition(0) on the RecyclerView to ensure that the user can always see all items when searching for something. Otherwise the RecyclerView might stay in a scrolled down position while filtering and subsequently hide a few items. Scrolling to the top ensures a better user experience while searching.

The only thing left to do now is to implement filter() itself:

private static List<ExampleModel> filter(List<ExampleModel> models, String query) {
    final String lowerCaseQuery = query.toLowerCase();

    final List<ExampleModel> filteredModelList = new ArrayList<>();
    for (ExampleModel model : models) {
        final String text = model.getText().toLowerCase();
        if (text.contains(lowerCaseQuery)) {
            filteredModelList.add(model);
        }
    }
    return filteredModelList;
}

The first thing we do here is call toLowerCase() on the query string. We don't want our search function to be case sensitive and by calling toLowerCase() on all strings we compare we can ensure that we return the same results regardless of case. It then just iterates through all the models in the List we passed into it and checks if the query string is contained in the text of the model. If it is then the model is added to the filtered List.

And that's it! The above code will run on API level 7 and above and starting with API level 11 you get item animations for free!

I realize that this is a very detailed description which probably makes this whole thing seem more complicated than it really is, but there is a way we can generalize this whole problem and make implementing an Adapter based on a SortedList much simpler.

Generalizing the problem and simplifying the Adapter

In this section I am not going to go into much detail - partly because I am running up against the character limit for answers on Stack Overflow but also because most of it already explained above - but to summarize the changes: We can implemented a base Adapter class which already takes care of dealing with the SortedList as well as binding models to ViewHolder instances and provides a convenient way to implement an Adapter based on a SortedList. For that we have to do two things:

• We need to create a ViewModel interface which all model classes have to implement
• We need to create a ViewHolder subclass which defines a bind() method the Adapter can use to bind models automatically.

This allows us to just focus on the content which is supposed to be displayed in the RecyclerView by just implementing the models and there corresponding ViewHolder implementations. Using this base class we don't have to worry about the intricate details of the Adapter and its SortedList.

SortedListAdapter

Because of the character limit for answers on StackOverflow I can't go through each step of implementing this base class or even add the full source code here, but you can find the full source code of this base class - I called it SortedListAdapter - in this GitHub Gist.

To make your life simple I have published a library on jCenter which contains the SortedListAdapter! If you want to use it then all you need to do is add this dependency to your app's build.gradle file:

compile 'com.github.wrdlbrnft:sorted-list-adapter:0.2.0.1'

You can find more information about this library on the library homepage.

Using the SortedListAdapter

To use the SortedListAdapter we have to make two changes:

• Change the ViewHolder so that it extends SortedListAdapter.ViewHolder. The type parameter should be the model which should be bound to this ViewHolder - in this case ExampleModel. You have to bind data to your models in performBind() instead of bind().

  public class ExampleViewHolder extends SortedListAdapter.ViewHolder<ExampleModel> {
  
      private final ItemExampleBinding mBinding;
  
      public ExampleViewHolder(ItemExampleBinding binding) {
          super(binding.getRoot());
          mBinding = binding;
      }
  
      @Override
      protected void performBind(ExampleModel item) {
          mBinding.setModel(item);
      }
  }
  

• Make sure that all your models implement the ViewModel interface:

  public class ExampleModel implements SortedListAdapter.ViewModel {
      ...
  }
  

After that we just have to update the ExampleAdapter to extend SortedListAdapter and remove everything we don't need anymore. The type parameter should be the type of model you are working with - in this case ExampleModel. But if you are working with different types of models then set the type parameter to ViewModel.

public class ExampleAdapter extends SortedListAdapter<ExampleModel> {

    public ExampleAdapter(Context context, Comparator<ExampleModel> comparator) {
        super(context, ExampleModel.class, comparator);
    }

    @Override
    protected ViewHolder<? extends ExampleModel> onCreateViewHolder(LayoutInflater inflater, ViewGroup parent, int viewType) {
        final ItemExampleBinding binding = ItemExampleBinding.inflate(inflater, parent, false);
        return new ExampleViewHolder(binding);
    }

    @Override
    protected boolean areItemsTheSame(ExampleModel item1, ExampleModel item2) {
        return item1.getId() == item2.getId();
    }

    @Override
    protected boolean areItemContentsTheSame(ExampleModel oldItem, ExampleModel newItem) {
        return oldItem.equals(newItem);
    }
}

After that we are done! However one last thing to mention: The SortedListAdapter does not have the same add(), remove() or replaceAll() methods our original ExampleAdapter had. It uses a separate Editor object to modify the items in the list which can be accessed through the edit() method. So if you want to remove or add items you have to call edit() then add and remove the items on this Editor instance and once you are done, call commit() on it to apply the changes to the SortedList:

mAdapter.edit()
        .remove(modelToRemove)
        .add(listOfModelsToAdd)
        .commit();

All changes you make this way are batched together to increase performance. The replaceAll() method we implemented in the chapters above is also present on this Editor object:

mAdapter.edit()
        .replaceAll(mModels)
        .commit();

If you forget to call commit() then none of your changes will be applied!

If possible, use NumberUtils in Apache Commons Lang - plenty of great utilities there.

https://commons.apache.org/proper/commons-lang/javadocs/api-3.1/org/apache/commons/lang3/math/NumberUtils.html#max(int[])

NumberUtils.max(int[])

Usage:

control.InvokeIfRequired(c => c.Visible = false);

return control.InvokeIfRequired(c => {
    c.Visible = value

    return c.Visible;
});

Code:

using System;
using System.ComponentModel;

namespace Extensions
{
    public static class SynchronizeInvokeExtensions
    {
        public static void InvokeIfRequired<T>(this T obj, Action<T> action)
            where T : ISynchronizeInvoke
        {
            if (obj.InvokeRequired)
            {
                obj.Invoke(action, new object[] { obj });
            }
            else
            {
                action(obj);
            }
        }

        public static TOut InvokeIfRequired<TIn, TOut>(this TIn obj, Func<TIn, TOut> func) 
            where TIn : ISynchronizeInvoke
        {
            return obj.InvokeRequired
                ? (TOut)obj.Invoke(func, new object[] { obj })
                : func(obj);
        }
    }
}

This is correct. You can also do :

A[] a = new A[] { new A("args"), new A("other args"), .. };

This syntax can also be used to create and initialize an array anywhere, such as in a method argument:

someMethod( new A[] { new A("args"), new A("other args"), . . } )

The following code changes the hexadecimal string to a byte array by parsing the string byte-by-byte.

public static byte[] ConvertHexStringToByteArray(string hexString)
{
    if (hexString.Length % 2 != 0)
    {
        throw new ArgumentException(String.Format(CultureInfo.InvariantCulture, "The binary key cannot have an odd number of digits: {0}", hexString));
    }

    byte[] data = new byte[hexString.Length / 2];
    for (int index = 0; index < data.Length; index++)
    {
        string byteValue = hexString.Substring(index * 2, 2);
        data[index] = byte.Parse(byteValue, NumberStyles.HexNumber, CultureInfo.InvariantCulture);
    }

    return data; 
}

esp stands for "Extended Stack Pointer".....ebp for "Something Base Pointer"....and eip for "Something Instruction Pointer"...... The stack Pointer points to the offset address of the stack segment. The Base Pointer points to the offset address of the extra segment. The Instruction Pointer points to the offset address of the code segment. Now, about the segments...they are small 64KB divisions of the processors memory area.....This process is known as Memory Segmentation. I hope this post was helpful.

Use extend to add a list comprehension to the end.

l.extend([x for i in range(100)])

See the Python docs for more information.

If you really want to create an array rather than a list use either

String[] names = ["lucas", "Fred", "Mary"]

or

def names = ["lucas", "Fred", "Mary"].toArray()

The newer iCalendar format, with more data attached, includes information about the person who created the event, so that when it is imported into Outlook (for example), changes to that event are communicated via email to the creator. This can be helpful when you need to inform others of any changes.

However, when I am just exporting an event from one of my calendars to another, I prefer to use vCalendar, since this does not require sending an email message to the creator (usually myself) if I make a change or delete something.

Go to "Tomcat Directory"/bin directory

if Linux then create setenv.sh else if Windows then create setenv.bat

content of setenv.* file :

export CATALINA_OPTS="$CATALINA_OPTS -Xms512m"
export CATALINA_OPTS="$CATALINA_OPTS -Xmx8192m"
export CATALINA_OPTS="$CATALINA_OPTS -XX:MaxPermSize=256m"

after this restart tomcat with new params.

explanation and full information is here

By the way, in C# 3.5 you can instantiate your object's properties like so:

Person TOM=new Person 
{ 
   title = "My title", ID = 1 
};

But again, properties must be public.

McAfee was blocking it for me. I had to allow the program in the access protection rules

1. Open VirusScan
2. Right click on Access Protection and choose Properties
3. Click on "Anti-virus Standard Protection"
4. Select rule "Prevent mass mailing worms from sending mail" and click edit
5. Add the application to the Processes to exclude list and click OK

Secondary data files are optional, are user-defined, and store user data. Secondary files can be used to spread data across multiple disks by putting each file on a different disk drive. Additionally, if a database exceeds the maximum size for a single Windows file, you can use secondary data files so the database can continue to grow.

Source: MSDN: Understanding Files and Filegroups

The recommended file name extension for secondary data files is .ndf, but this is not enforced.

var currentYear =  (new Date()).getFullYear();   
var twoLastDigits = currentYear%100;

var formatedTwoLastDigits = "";

if (twoLastDigits <10 ) {
    formatedTwoLastDigits = "0" + twoLastDigits;
} else {
    formatedTwoLastDigits = "" + twoLastDigits;
}

it is better to use json after post your resuest like below

  var clien = new RestClient("https://smple.com/");
  var request = new RestRequest("index", Method.POST);
  request.AddHeader("Sign", signinstance);    
  request.AddJsonBody(JsonConvert.SerializeObject(yourclass));
  var response = client.Execute<YourReturnclassSample>(request);
  if (response.StatusCode == System.Net.HttpStatusCode.Created)
   {
       return Ok(response.Content);
   }

The best way to do this is using Behaviur Subject, here is an example:

var sub = new rxjs.BehaviorSubject([0, 1])
sub.next([2, 3])
setTimeout(() => {sub.next([4, 5])}, 1500)
sub.subscribe(a => console.log(a)) //2, 3 (current value) -> wait 2 sec -> 4, 5

<TextView 
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="?"/>

You can get here more options.

As to the cause, the <f:attribute> is specific to the component itself (populated during view build time), not to the iterated row (populated during view render time).

There are several ways to achieve the requirement.

1. If your servletcontainer supports a minimum of Servlet 3.0 / EL 2.2, then just pass it as an argument of action/listener method of UICommand component or AjaxBehavior tag. E.g.

    <h:commandLink action="#{bean.insert(item.id)}" value="insert" />
   

   In combination with:

    public void insert(Long id) {
        // ...
    }
   

   This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   You can even pass the entire item object:

    <h:commandLink action="#{bean.insert(item)}" value="insert" />
   

   with:

    public void insert(Item item) {
        // ...
    }
   

   On Servlet 2.5 containers, this is also possible if you supply an EL implementation which supports this, like as JBoss EL. For configuration detail, see this answer.

   ---

2. Use <f:param> in UICommand component. It adds a request parameter.

    <h:commandLink action="#{bean.insert}" value="insert">
        <f:param name="id" value="#{item.id}" />
    </h:commandLink>
   

   If your bean is request scoped, let JSF set it by @ManagedProperty

    @ManagedProperty(value="#{param.id}")
    private Long id; // +setter
   

   Or if your bean has a broader scope or if you want more fine grained validation/conversion, use <f:viewParam> on the target view, see also f:viewParam vs @ManagedProperty:

    <f:viewParam name="id" value="#{bean.id}" required="true" />
   

   Either way, this has the advantage that the datamodel doesn't necessarily need to be preserved for the form submit (for the case that your bean is request scoped).

   ---

3. Use <f:setPropertyActionListener> in UICommand component. The advantage is that this removes the need for accessing the request parameter map when the bean has a broader scope than the request scope.

    <h:commandLink action="#{bean.insert}" value="insert">
        <f:setPropertyActionListener target="#{bean.id}" value="#{item.id}" />
    </h:commandLink>
   

   In combination with

    private Long id; // +setter
   

   It'll be just available by property id in action method. This only requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   ---

4. Bind the datatable value to DataModel<E> instead which in turn wraps the items.

    <h:dataTable value="#{bean.model}" var="item">
   

   with

    private transient DataModel<Item> model;
   
    public DataModel<Item> getModel() {
        if (model == null) {
            model = new ListDataModel<Item>(items);
        }
        return model;
    }
   

   (making it transient and lazily instantiating it in the getter is mandatory when you're using this on a view or session scoped bean since DataModel doesn't implement Serializable)

   Then you'll be able to access the current row by DataModel#getRowData() without passing anything around (JSF determines the row based on the request parameter name of the clicked command link/button).

    public void insert() {
        Item item = model.getRowData();
        Long id = item.getId();
        // ...
    }
   

   This also requires that the datamodel is preserved for the form submit request. Best is to put the bean in the view scope by @ViewScoped.

   ---

5. Use Application#evaluateExpressionGet() to programmatically evaluate the current #{item}.

    public void insert() {
        FacesContext context = FacesContext.getCurrentInstance();
        Item item = context.getApplication().evaluateExpressionGet(context, "#{item}", Item.class);
        Long id = item.getId();
        // ...
    }
   

   ---

Which way to choose depends on the functional requirements and whether the one or the other offers more advantages for other purposes. I personally would go ahead with #1 or, when you'd like to support servlet 2.5 containers as well, with #2.

Here you've got a very detailed explanation of their differences

http://kyleschaeffer.com/development/css-font-size-em-vs-px-vs-pt-vs/

The jist of it (from source)

Pixels are fixed-size units that are used in screen media (i.e. to be read on the computer screen). Pixel stands for "picture element" and as you know, one pixel is one little "square" on your screen. Points are traditionally used in print media (anything that is to be printed on paper, etc.). One point is equal to 1/72 of an inch. Points are much like pixels, in that they are fixed-size units and cannot scale in size.

IF vertical align won't work use padding. padding-top: 10px; it will shift the text to the bottom or padding-bottom: 10px; to shift the text in the text box to top

adjust the padding size till it suit the size you want. Thats the hack

While base64 encoding is safe and one could argue "the right answer", I arrived here looking for a way to convert a Java byte array to/from a Java String as-is. That is, where each member of the byte array remains intact in its String counterpart, with no extra space required for encoding/transport.

This answer describing 8bit transparent encodings was very helpful for me. I used ISO-8859-1 on terabytes of binary data to convert back and forth successfully (binary <-> String) without the inflated space requirements needed for a base64 encoding, so is safe for my use-case - YMMV.

This was also helpful in explaining when/if you should experiment.

It seems that you have forgotten to add your state server address in the config file.

 <sessionstate mode="StateServer" timeout="20" server="127.0.0.1" port="42424" />

This won't help you step through code or break on errors, but it's a useful way to get the same debug console for your project on all browsers.

myLog = function() {
    if (!myLog._div) { myLog.createDiv(); }

    var logEntry = document.createElement('span');
    for (var i=0; i < arguments.length; i++) {
        logEntry.innerHTML += myLog.toJson(arguments[i]) + '<br />';
    }
    logEntry.innerHTML += '<br />';

    myLog._div.appendChild(logEntry);
}
myLog.createDiv = function() {
    myLog._div = document.body.appendChild(document.createElement('div'));
    var props = {
        position:'absolute', top:'10px', right:'10px', background:'#333', border:'5px solid #333', 
        color: 'white', width: '400px', height: '300px', overflow: 'auto', fontFamily: 'courier new',
        fontSize: '11px', whiteSpace: 'nowrap'
    }
    for (var key in props) { myLog._div.style[key] = props[key]; }
}
myLog.toJSON = function(obj) {
    if (typeof window.uneval == 'function') { return uneval(obj); }
    if (typeof obj == 'object') {
        if (!obj) { return 'null'; }
        var list = [];
        if (obj instanceof Array) {
            for (var i=0;i < obj.length;i++) { list.push(this.toJson(obj[i])); }
            return '[' + list.join(',') + ']';
        } else {
            for (var prop in obj) { list.push('"' + prop + '":' + this.toJson(obj[prop])); }
            return '{' + list.join(',') + '}';
        }
    } else if (typeof obj == 'string') {
        return '"' + obj.replace(/(["'])/g, '\\$1') + '"';
    } else {
        return new String(obj);
    }
}

myLog('log statement');
myLog('logging an object', { name: 'Marcus', likes: 'js' });

This is put together pretty hastily and is a bit sloppy, but it's useful nonetheless and can be improved easily!

If you want to save the changes on the log messages, use the batch script from the answer above from @patmortech (https://stackoverflow.com/a/468475),
who copied the script from https://stackoverflow.com/a/68850,
and add these lines between if "%bIsEmpty%" == "true" goto ERROR_EMPTY and goto :eofbefore:

set outputFile=%repos%\log-change-history.txt

echo User '%user%' changes log message in rev %rev% on %date% %time%.>>%outputFile%
echo ----- Old message: ----->>%outputFile%
svnlook propget --revprop %repos% svn:log -r %rev% >>%outputFile%
echo.>>%outputFile%
echo ----- New message: ----->>%outputFile%
for /f "tokens=*" %%g in ('find /V ""') do (echo %%g >>%outputFile%)
echo ---------->>%outputFile%
echo.>>%outputFile%

It will create a text file log-change-history.txt in the repo folder on the server and append each log change notification.

All you need to do is add the mat-icon-button directive to the button element in your template. Within the button element specify your desired icon with a mat-icon component.

You'll need to import MatButtonModule and MatIconModule in your app module file.

From the Angular Material buttons example page, hit the view code button and you'll see several examples which use the material icons font, eg.

<button mat-icon-button>
  <mat-icon aria-label="Example icon-button with a heart icon">favorite</mat-icon>
</button>

In your case, use

<mat-icon>thumb_up</mat-icon>

As per the getting started guide at https://material.angular.io/guide/getting-started, you'll need to load the material icon font in your index.html.

<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Or import it in your global styles.scss.

@import url("https://fonts.googleapis.com/icon?family=Material+Icons");

As it mentions, any icon font can be used with the mat-icon component.

The reason eval and exec are so dangerous is that the default compile function will generate bytecode for any valid python expression, and the default eval or exec will execute any valid python bytecode. All the answers to date have focused on restricting the bytecode that can be generated (by sanitizing input) or building your own domain-specific-language using the AST.

Instead, you can easily create a simple eval function that is incapable of doing anything nefarious and can easily have runtime checks on memory or time used. Of course, if it is simple math, than there is a shortcut.

c = compile(stringExp, 'userinput', 'eval')
if c.co_code[0]==b'd' and c.co_code[3]==b'S':
    return c.co_consts[ord(c.co_code[1])+ord(c.co_code[2])*256]

The way this works is simple, any constant mathematic expression is safely evaluated during compilation and stored as a constant. The code object returned by compile consists of d, which is the bytecode for LOAD_CONST, followed by the number of the constant to load (usually the last one in the list), followed by S, which is the bytecode for RETURN_VALUE. If this shortcut doesn't work, it means that the user input isn't a constant expression (contains a variable or function call or similar).

This also opens the door to some more sophisticated input formats. For example:

stringExp = "1 + cos(2)"

This requires actually evaluating the bytecode, which is still quite simple. Python bytecode is a stack oriented language, so everything is a simple matter of TOS=stack.pop(); op(TOS); stack.put(TOS) or similar. The key is to only implement the opcodes that are safe (loading/storing values, math operations, returning values) and not unsafe ones (attribute lookup). If you want the user to be able to call functions (the whole reason not to use the shortcut above), simple make your implementation of CALL_FUNCTION only allow functions in a 'safe' list.

from dis import opmap
from Queue import LifoQueue
from math import sin,cos
import operator

globs = {'sin':sin, 'cos':cos}
safe = globs.values()

stack = LifoQueue()

class BINARY(object):
    def __init__(self, operator):
        self.op=operator
    def __call__(self, context):
        stack.put(self.op(stack.get(),stack.get()))

class UNARY(object):
    def __init__(self, operator):
        self.op=operator
    def __call__(self, context):
        stack.put(self.op(stack.get()))


def CALL_FUNCTION(context, arg):
    argc = arg[0]+arg[1]*256
    args = [stack.get() for i in range(argc)]
    func = stack.get()
    if func not in safe:
        raise TypeError("Function %r now allowed"%func)
    stack.put(func(*args))

def LOAD_CONST(context, arg):
    cons = arg[0]+arg[1]*256
    stack.put(context['code'].co_consts[cons])

def LOAD_NAME(context, arg):
    name_num = arg[0]+arg[1]*256
    name = context['code'].co_names[name_num]
    if name in context['locals']:
        stack.put(context['locals'][name])
    else:
        stack.put(context['globals'][name])

def RETURN_VALUE(context):
    return stack.get()

opfuncs = {
    opmap['BINARY_ADD']: BINARY(operator.add),
    opmap['UNARY_INVERT']: UNARY(operator.invert),
    opmap['CALL_FUNCTION']: CALL_FUNCTION,
    opmap['LOAD_CONST']: LOAD_CONST,
    opmap['LOAD_NAME']: LOAD_NAME
    opmap['RETURN_VALUE']: RETURN_VALUE,
}

def VMeval(c):
    context = dict(locals={}, globals=globs, code=c)
    bci = iter(c.co_code)
    for bytecode in bci:
        func = opfuncs[ord(bytecode)]
        if func.func_code.co_argcount==1:
            ret = func(context)
        else:
            args = ord(bci.next()), ord(bci.next())
            ret = func(context, args)
        if ret:
            return ret

def evaluate(expr):
    return VMeval(compile(expr, 'userinput', 'eval'))

Obviously, the real version of this would be a bit longer (there are 119 opcodes, 24 of which are math related). Adding STORE_FAST and a couple others would allow for input like 'x=5;return x+x or similar, trivially easily. It can even be used to execute user-created functions, so long as the user created functions are themselves executed via VMeval (don't make them callable!!! or they could get used as a callback somewhere). Handling loops requires support for the goto bytecodes, which means changing from a for iterator to while and maintaining a pointer to the current instruction, but isn't too hard. For resistance to DOS, the main loop should check how much time has passed since the start of the calculation, and certain operators should deny input over some reasonable limit (BINARY_POWER being the most obvious).

While this approach is somewhat longer than a simple grammar parser for simple expressions (see above about just grabbing the compiled constant), it extends easily to more complicated input, and doesn't require dealing with grammar (compile take anything arbitrarily complicated and reduces it to a sequence of simple instructions).

I struggled while working MS OCR Read API which returns back angle of rotation in range (-180, 180]. So I have to do an extra step of converting negative angles to positive. I hope someone struggling with point rotation with negative or positive angles can use the following.

def rotate(origin, point, angle):
    """
    Rotate a point counter-clockwise by a given angle around a given origin.
    """
    # Convert negative angles to positive
    angle = normalise_angle(angle)

    # Convert to radians
    angle = math.radians(angle)

    # Convert to radians
    ox, oy = origin
    px, py = point
    
    # Move point 'p' to origin (0,0)
    _px = px - ox
    _py = py - oy
    
    # Rotate the point 'p' 
    qx = (math.cos(angle) * _px) - (math.sin(angle) * _py)
    qy = (math.sin(angle) * _px) + (math.cos(angle) * _py)
    
    # Move point 'p' back to origin (ox, oy)
    qx = ox + qx
    qy = oy + qy
    
    return [qx, qy]


def normalise_angle(angle):
    """ If angle is negative then convert it to positive. """
    if (angle != 0) & (abs(angle) == (angle * -1)):
        angle = 360 + angle
    return angle

Android Studio 2.2 came out with the ability to use ndk-build and cMake. Though, we had to wait til 2.2.3 for the Application.mk support. I've tried it, it works...though, my variables aren't showing up in the debugger. I can still query them via command line though.

You need to do something like this:

externalNativeBuild{
   ndkBuild{
        path "Android.mk"
    }
}

defaultConfig {
  externalNativeBuild{
    ndkBuild {
      arguments "NDK_APPLICATION_MK:=Application.mk"
      cFlags "-DTEST_C_FLAG1"  "-DTEST_C_FLAG2"
      cppFlags "-DTEST_CPP_FLAG2"  "-DTEST_CPP_FLAG2"
      abiFilters "armeabi-v7a", "armeabi"
    }
  } 
}

See http://tools.android.com/tech-docs/external-c-builds

NB: The extra nesting of externalNativeBuild inside defaultConfig was a breaking change introduced with Android Studio 2.2 Preview 5 (July 8, 2016). See the release notes at the above link.

This is not directly related to the initial issue, but probably will help somebody.

I faced same issue when was trying to send similar request using domain account. So mine issue was in not escaped character in login name.

Bad example:

'ABC\username'

Good example:

'ABC\\username'

The length of the array is 7, the NUL character \0 still counts as a character and the string is still terminated with an implicit \0

See this link to see a working example

Note that had you declared str as char str[6]= "Hello\0"; the length would be 6 because the implicit NUL is only added if it can fit (which it can't in this example.)

§ 6.7.8/p14
An array of character type may be initialized by a character string literal, optionally enclosed in braces. Sucessive characters of the character string literal (including the terminating null character if there is room or if the array is of unknown size) initialize the elements of the array.

Examples

char str[] = "Hello\0"; /* sizeof == 7, Explicit + Implicit NUL */
char str[5]= "Hello\0"; /* sizeof == 5, str is "Hello" with no NUL (no longer a C-string, just an array of char). This may trigger compiler warning */
char str[6]= "Hello\0"; /* sizeof == 6, Explicit NUL only */
char str[7]= "Hello\0"; /* sizeof == 7, Explicit + Implicit NUL */
char str[8]= "Hello\0"; /* sizeof == 8, Explicit + two Implicit NUL */

showInventory(player);     // I get the error here.

void showInventory(player& obj) {   // By Johnny :D

this means that player is an datatype and showInventory expect an referance to an variable of type player.

so the correct code will be

  void showInventory(player& obj) {   // By Johnny :D
    for(int i = 0; i < 20; i++) {
        std::cout << "\nINVENTORY:\n" + obj.getItem(i);
        i++;
        std::cout << "\t\t\t" + obj.getItem(i) + "\n";
        i++;
    }
    }

players myPlayers[10];

    std::string toDo() //BY KEATON
    {
    std::string commands[5] =   // This is the valid list of commands.
        {"help", "inv"};

    std::string ans;
    std::cout << "\nWhat do you wish to do?\n>> ";
    std::cin >> ans;

    if(ans == commands[0]) {
        helpMenu();
        return NULL;
    }
    else if(ans == commands[1]) {
        showInventory(myPlayers[0]);     // or any other index,also is not necessary to have an array
        return NULL;
    }

}

Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.

Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).

When you do spam = "green", you have bound the name spam to the string object "green"; if you then do eggs = spam you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs, to the same object ("green" in this case). If you then bind spam to something else (spam = 3.14159) eggs will still be bound to "green".

When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).

With for-loops utilizing lists, there are two basic ways to assign back to the list:

for i, item in enumerate(some_list):
    some_list[i] = process(item)

or

new_list = []
for item in some_list:
    new_list.append(process(item))
some_list[:] = new_list

Notice the [:] on that last some_list -- it is causing a mutation of some_list's elements (setting the entire thing to new_list's elements) instead of rebinding the name some_list to new_list. Is this important? It depends! If you have other names besides some_list bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list.

Set the PATH as below:

In the csh shell - type setenv PATH "$PATH:/usr/local/bin/python" and press Enter.

In the bash shell (Linux) - type export PATH="$PATH:/usr/local/bin/python" and press Enter.

In the sh or ksh shell - type PATH="$PATH:/usr/local/bin/python" and press Enter.

Note - /usr/local/bin/python is the path of the Python directory

now run as below:

-bash-4.2$ python test.py

Just to elucidate a bit on @emsr's comment in @unwind's answer, if one is not fortunate enough to have a C++11 compiler (say GCC 4.2.1), and one wants to embed the newlines in the string (either char * or class string), one can write something like this:

const char *text =
  "This text is pretty long, but will be\n"
  "concatenated into just a single string.\n"
  "The disadvantage is that you have to quote\n"
  "each part, and newlines must be literal as\n"
  "usual.";

Very obvious, true, but @emsr's short comment didn't jump out at me when I read this the first time, so I had to discover this for myself. Hopefully, I've saved someone else a few minutes.

If you use "format-table" you can use -hidetableheaders

I also just ran in to a similar problem, that is service apache2 reload fails but prints no useful information. This is because the script in /etc/init.d/apache (on Debian, at least) eats the output of the apache2ctl configtest command it runs to sanitize the Apache config.

An easy solution to get a more meaningful explanation for the failure is to run apache2ctl configtest again yourself, which will print the (hopefully useful) error messages to the console.

Well, I have tried something I hope it helps ..

They changed the schema a little bit ..

Use the following :

1- Change the AccessDataSource to SQLDataSource in the toolbox.

2- In the drop down menu choose your access database (xxxx.accdb or xxxx.mdb)

3- Next -> Next -> Test Query -> Finish.

Worked for me.

May be with:

SELECT count(*) FROM `table` 
where 
    created_at>='2011-03-17 06:42:10' and created_at<='2011-03-17 07:42:50';

or use between:

SELECT count(*) FROM `table` 
where 
    created_at between '2011-03-17 06:42:10' and '2011-03-17 07:42:50';

You can change the datetime as per your need. May be use curdate() or now() to get the desired dates.

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

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

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

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

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

It's also useful to note that you can run the underlying MapReduce jobs with either the source or target cluster like so:

hadoop --config /path/to/hadoop/config distcp <src> <dst>

template <typename T>
T reverse(T n, size_t b = sizeof(T) * CHAR_BIT)
{
    assert(b <= std::numeric_limits<T>::digits);

    T rv = 0;

    for (size_t i = 0; i < b; ++i, n >>= 1) {
        rv = (rv << 1) | (n & 0x01);
    }

    return rv;
}

EDIT:

Converted it to a template with the optional bitcount

I believe:

String.Format("{0:0.00}",Sale);

Should do it.

See Link String Format Examples C#

The easiest way to convert a std::string to a LPWSTR is in my opinion:

1. Convert the std::string to a std::vector<wchar_t>
2. Take the address of the first wchar_t in the vector.

std::vector<wchar_t> has a templated ctor which will take two iterators, such as the std::string.begin() and .end() iterators. This will convert each char to a wchar_t, though. That's only valid if the std::string contains ASCII or Latin-1, due to the way Unicode values resemble Latin-1 values. If it contains CP1252 or characters from any other encoding, it's more complicated. You'll then need to convert the characters.

Sounds like you need moment.js

e.g.

moment().subtract('days', 6).calendar();

=> last Sunday at 8:23 PM

moment().startOf('hour').fromNow();

=> 26 minutes ago

Edit:

Pure JS date diff calculation:

var date1 = new Date("7/Nov/2012 20:30:00");_x000D_
var date2 = new Date("20/Nov/2012 19:15:00");_x000D_
_x000D_
var diff = date2.getTime() - date1.getTime();_x000D_
_x000D_
var days = Math.floor(diff / (1000 * 60 * 60 * 24));_x000D_
diff -=  days * (1000 * 60 * 60 * 24);_x000D_
_x000D_
var hours = Math.floor(diff / (1000 * 60 * 60));_x000D_
diff -= hours * (1000 * 60 * 60);_x000D_
_x000D_
var mins = Math.floor(diff / (1000 * 60));_x000D_
diff -= mins * (1000 * 60);_x000D_
_x000D_
var seconds = Math.floor(diff / (1000));_x000D_
diff -= seconds * (1000);_x000D_
_x000D_
document.write(days + " days, " + hours + " hours, " + mins + " minutes, " + seconds + " seconds");

Do following will select your file automatically all time.

1. Right click on Project/Packages area > Autoscroll to Source.
2. Right click on Project/Packages area > Autoscroll from Source.

I think the only way to handle this is to use JavaScript

Try this Invert text color of a specific element

If you do this with css3 it's only compatible with the newest browser versions.

I don't think there is a built in way, but I think the easiest would be

  char[] alpha = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".ToCharArray();

tf.nn.softmax computes the forward propagation through a softmax layer. You use it during evaluation of the model when you compute the probabilities that the model outputs.

tf.nn.softmax_cross_entropy_with_logits computes the cost for a softmax layer. It is only used during training.

The logits are the unnormalized log probabilities output the model (the values output before the softmax normalization is applied to them).

Something nobody has mentioned is that the DB guarantees atomic actions, transactional integrity and deals with concurrency. Even referentially integrity is out of the window with a filesystem - so how do you know your file names are really still correct?

If you have your images in a file-system and someone is reading the file as you're writing a new version or even deleting the file - what happens?

We use blobs because they're easier to manage (backup, replication, transfer) too. They work well for us.

Just sharing my experience on this. I was having this same issue. My query was like:

select table1.column2 from table1

However, table1 did not have column2 column.

Don't ever use the setInterval or setTimeout functions for time measuring! They are unreliable, and it is very likely that the JS execution scheduling during a documents parsing and displaying is delayed.

Instead, use the Date object to create a timestamp when you page began loading, and calculate the difference to the time when the page has been fully loaded:

<doctype html>
<html>
    <head>
        <script type="text/javascript">
            var timerStart = Date.now();
        </script>
        <!-- do all the stuff you need to do -->
    </head>
    <body>
        <!-- put everything you need in here -->

        <script type="text/javascript">
             $(document).ready(function() {
                 console.log("Time until DOMready: ", Date.now()-timerStart);
             });
             $(window).load(function() {
                 console.log("Time until everything loaded: ", Date.now()-timerStart);
             });
        </script>
    </body>
</html>

You can do it using named-entity recognition (NER). It's fairly simple and there are out-of-the-shelf tools out there to do it, such as spaCy.

NER is an NLP task where a neural network (or other method) is trained to detect certain entities, such as names, places, dates and organizations.

Example:

Sponge Bob went to South beach, he payed a ticket of $200!
I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.

Returns:

Just be aware that this is not 100%!

Here are a little snippet for you to try out:

import spacy

phrases = ['Sponge Bob went to South beach, he payed a ticket of $200!', 'I know, Michael is a good person, he goes to McDonalds, but donates to charity at St. Louis street.']
nlp = spacy.load('en')
for phrase in phrases:
   doc = nlp(phrase)
   replaced = ""
   for token in doc:
      if token in doc.ents:
         replaced+="XXXX "
      else:
         replaced+=token.text+" "

Read more here: https://spacy.io/usage/linguistic-features#named-entities

You could, instead of replacing with XXXX, replace based on the entity type, like:

if ent.label_ == "PERSON":
   replaced += "<PERSON> "

Then:

import re, random

personames = ["Jack", "Mike", "Bob", "Dylan"]

phrase = re.replace("<PERSON>", random.choice(personames), phrase)

 scope: false
 transclude: false

and you will have the same scope(with parent element)

$scope.$watch(...

There are a lot of ways how to access parent scope depending on this two options scope& transclude.

We can have two ways of calling the functions written in pgadmin for postgre sql database.

Suppose we have defined the function as below:

CREATE OR REPLACE FUNCTION helloWorld(name text) RETURNS void AS $helloWorld$
DECLARE
BEGIN
    RAISE LOG 'Hello, %', name;
END;
$helloWorld$ LANGUAGE plpgsql;

We can call the function helloworld in one of the following way:

SELECT "helloworld"('myname');

SELECT public.helloworld('myname')

Pod `Alamofire` has `NetworkReachabilityManager`, you just have to create one function 

func isConnectedToInternet() ->Bool {
        return NetworkReachabilityManager()!.isReachable
}

try this it will work...it will give you the index of selected row index...

int rowindex = dataGridView1.CurrentRow.Index;
MessageBox.Show(rowindex.ToString());

Though I upvoted the answer marked as correct. I wanted to touch on a few things for anyone stumbling upon this.

In general, if you're filtering specifically on Date values alone. Microsoft recommends using the language neutral format of ymd or y-m-d.

Note that the form '2007-02-12' is considered language-neutral only for the data types DATE, DATETIME2, and DATETIMEOFFSET.

To do a date comparison using the aforementioned approach is simple. Consider the following, contrived example.

--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)

select 
    * 
from 
    Sales.Orders
where
    CONVERT(char(8), OrderDate, 112) = @filterDate

In a perfect world, performing any manipulation to the filtered column should be avoided because this can prevent SQL Server from using indexes efficiently. That said, if the data you're storing is only ever concerned with the date and not time, consider storing as DATETIME with midnight as the time. Because:

When SQL Server converts the literal to the filtered column’s type, it assumes midnight when a time part isn’t indicated. If you want such a filter to return all rows from the specified date, you need to ensure that you store all values with midnight as the time.

Thus, assuming you are only concerned with date, and store your data as such. The above query can be simplified to:

--112 is ISO format 'YYYYMMDD'
declare @filterDate char(8) = CONVERT(char(8), GETDATE(), 112)

select 
    * 
from 
    Sales.Orders
where
    OrderDate = @filterDate

As long as the column is not a unique identifier

UPDATE table set columnName = 0 where columnName is null

Then

Alter the table and set the field to non null and specify a default value of 0

this simple code work 100% all you need is changing 'lat','long' for address to show

<iframe src="http://maps.google.com/maps?q=25.3076008,51.4803216&z=16&output=embed" height="450" width="600"></iframe>

A NullPointerException means that one of the variables you are passing is null, but the code tries to use it like it is not.

For example, If I do this:

Integer myInteger = null;
int n = myInteger.intValue();

The code tries to grab the intValue of myInteger, but since it is null, it does not have one: a null pointer exception happens.

What this means is that your getTask method is expecting something that is not a null, but you are passing a null. Figure out what getTask needs and pass what it wants!

array1.NonIntersect(array2);

Nonintersect such operator is not present in Linq you should do

except -> union -> except

a.except(b).union(b.Except(a));

Your convention seems to be reasonable. If I were searching for your framework in the Maven repo, I would look for awesome-inhouse-framework-x.y.jar in com.mycompany.awesomeinhouseframework group directory. And I would find it there according to your convention.

Two simple rules work for me:

• reverse-domain-packages for groupId (since such are quite unique) with all the constrains regarding Java packages names
• project name as artifactId (keeping in mind that it should be jar-name friendly i.e. not contain characters that maybe invalid for a file name or just look weird)

The first one is easier, because, if you read it left to right you get: "If something AND somethingelse AND somethingelse THEN" , which is an easy to understand sentence. The second example reads "If something THEN if somethingelse THEN if something else THEN", which is clumsy.

Also, consider if you wanted to use some ORs in your clause - how would you do that in the second style?

If you happen to use Vavr(formerly known as Javaslang), this can be as easy as:

Iterable i = //...
Stream.ofAll(i);

There is another solution you can try by using only the css here is the answer i posted in another post: jQuery Accordion change font awesome icon class on click

You must add these lines in the web.config

Hope this helps.

Your focus is working before return false; ,After that is not working. You try this solution. Control after return false;

Put code in function:

function  validateNumber(){
    var mnumber = document.getElementById('mobileno').value; 
    if(mnumber.length >=10) {
        alert("Mobile Number Should be in 10 digits only"); 
        document.getElementById('mobileno').value = ""; 
        return false; 
    }else{
        return true;
    }
}

Caller function:

function submitButton(){
        if(!validateNumber()){
            document.getElementById('mobileno').focus();
            return false;
        }
}

HTML:

Input:<input type="text" id="mobileno">
<button onclick="submitButton();" >Submit</button>

create LOGIN guest WITH PASSWORD='guest@123', CHECK_POLICY = OFF;

Be sure when you want to exceute the following

DENY VIEW ANY DATABASE TO guest;

ALTER AUTHORIZATION ON DATABASE::BiddingSystemDB TO guest

Selected Database should be Master

On the server, try:

netstat -an 

and look to see if tcp port 22 is opened (use findstr in Windows or grep in Unix).

I have this problem,too.I just disable Workspace resolution,and then all was right.enter image description here

history.pushState(null, null, document.title);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.title);
});

This script will overwrite attempts to navigate back and forth with the state of the current page.

Update:

Some users have reported better success with using document.URL instead of document.title:

history.pushState(null, null, document.URL);
window.addEventListener('popstate', function () {
    history.pushState(null, null, document.URL);
});

simply: document.cookie="name=value;path=/";

There is a negative point to it

Now, the cookie will be available to all directories on the domain it is set from. If the website is just one of many at that domain, it’s best not to do this because everyone else will also have access to your cookie information.

You have to use:

document.addEventListener("turbolinks:load", function() {
  // your code here
})

from turbolinks doc.

After a lot of tries this command worked for me:

curl -v -F filename=image.jpg -F [email protected] http://localhost:8080/api/upload

Since mongo 3.6 you can use 'change stream': https://emptysqua.re/blog/driver-features-for-mongodb-3-6/#change-streams

To use it you need to create a change stream object by the 'watch' query, and for each change, you can do whatever you want...

python solution:

def update_at_by(change):
    update_fields = change["updateDescription"]["updatedFields"].keys()
    print("update_fields: {}".format(update_fields))

    collection = change["ns"]["coll"]
    db = change["ns"]["db"]
    key = change["documentKey"]

    if len(update_fields) == 1 and "update_at" in update_fields:
        pass  # to avoid recursion updates...
    else:
        client[db][collection].update(key, {"$set": {"update_at": datetime.now()}})


client = MongoClient("172.17.0.2")
db = client["Data"]

change_stream = db.watch()

for change in change_stream:
    print(change)
    update_ts_by(change)

Note, to use the change_stream object, your mongodb instance should run as 'replica set'. It can be done also as a 1-node replica set (almost no change then the standalone use):

Run mongo as a replica set: https://docs.mongodb.com/manual/tutorial/convert-standalone-to-replica-set/

Replica set configuration vs Standalone: Mongo DB - difference between standalone & 1-node replica set

In Eclipse 3.7, I found a terminal view plugin that I installed through Eclipse Marketplace. Details are as follow:

Local Terminal (Incubation) http://market.eclipsesource.com/yoxos/node/org.eclipse.tm.terminal.local.feature.group

A terminal emulation for local shells and external tools. Requires CDT Core 7.0 or later. Works on Linux, Solaris and Mac. Includes Source.

Side note, this terminal does not execute .bash_profile or .bashrc so you can do

source ~/.bash_profile

and (if this isn't sourced by `.bash_profile)

source ~/.bashrc

Update:

This is actually was base for Terminal plug-in for Eclipse fork. Quote from http://alexruiz.developerblogs.com/?p=2428

Alex, why not aiming for rejoining your work with the original TM Terminal? I’ve checked and haven’t found any bugzilla asking for missing features or pointing out bugs. There had been changes to the original Terminal control, so I’m not sure if all of your original reasons to clone it are still true.

No it doesn't need to be constant, the reason why his code above is wrong is because he needs to include a variable name before the declaration.

int row = 8;
int col= 8;
int x[row][col];

In Xcode that will compile and run without any issues, in M$ C++ compiler in .NET it won't compile, it will complain that you cannot use a non const literal to initialize array, the size needs to be known at compile time

The core idea of the solution is:

• create a new input element
• Add the type text
• append the element to the DOM

This can be done via this simple script:

var input = document.createElement('input');
input.setAttribute('type', 'text');
document.getElementById('parent').appendChild(input);

Now the question is, how to render this process dynamic. As stated in the question, there is another input where the user insert the number of input to generate. This can be done as follows:

function renderInputs(el){
  var n = el.value && parseInt(el.value, 10);
  if(isNaN(n)){
    return;
  }
  
  var input;
  var parent = document.getElementById("parent");
  
  cleanDiv(parent);
  for(var i=0; i<n; i++){
    input = document.createElement('input');
    input.setAttribute('type', 'text');
    parent.appendChild(input);
  }
}

function cleanDiv(div){
  div.innerHTML = '';
}

Insert number of input to generate: </br>
<input type="text" onchange="renderInputs(this)"/>

<div id="parent">
Generated inputs:
</div>

but usually adding just an input is not really usefull, it would be better to add a name to the input, so that it can be easily sent as a form. This snippet add also a name:

function renderInputs(el){
  var n = el.value;
  var input, label;
  var parent = document.getElementById("parent");
  cleanDiv(parent);
  
  el.value.split(',').forEach(function(name){
    input = document.createElement('input');
    input.setAttribute('type', 'text');
    input.setAttribute('name', name);
    label = document.createElement('label');
    label.setAttribute('for', name);
    label.innerText = name;
    parent.appendChild(label);
    parent.appendChild(input);
    parent.appendChild(document.createElement('br'));
  });
}

function cleanDiv(div){
  div.innerHTML = '';
}

Insert the names, separated by comma, of the inputs to generate: </br>
<input type="text" onchange="renderInputs(this)"/>
<br>
Generated inputs: </br>
<div id="parent">

</div>

First few lines: man head.

Append lines: use the >> operator (?) in Bash:

echo 'This goes at the end of the file' >> file

You can see if object has shape or not

def check_array(x):
    try:
        x.shape
        return True
    except:
        return False

You'll be wanting to use glob()

Example:

$files = glob('/path/to/dir/*.xml');

Here's a batch file, called base64encode.bat, that encodes base64.

@echo off
if not "%1" == "" goto :arg1exists
echo usage: base64encode input-file [output-file]
goto :eof
:arg1exists
set base64out=%2
if "%base64out%" == "" set base64out=con 
(
  set base64tmp=base64.tmp
  certutil -encode "%1" %base64tmp% > nul
  findstr /v /c:- %base64tmp%
  erase %base64tmp%
) > %base64out%

a = np.array([1,2,3,4,5,6,7,8,9])
b = a[(a>2) & (a<8)]

You can try this code

It work for me. I hope it can hepl you!

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

The problem is that your regex is a string, but html is bytes:

>>> type(html)
<class 'bytes'>

Since python doesn't know how those bytes are encoded, it throws an exception when you try to use a string regex on them.

You can either decode the bytes to a string:

html = html.decode('ISO-8859-1')  # encoding may vary!
title = re.findall(pattern, html)  # no more error

Or use a bytes regex:

regex = rb'<title>(,+?)</title>'
#        ^

In this particular context, you can get the encoding from the response headers:

with urllib.request.urlopen(url) as response:
    encoding = response.info().get_param('charset', 'utf8')
    html = response.read().decode(encoding)

See the urlopen documentation for more details.

Suppose you have following lines of code

MyUrl = "www.google.com" #Your url goes here
urllib.urlretrieve(MyUrl)

If you are receiving following error message

AttributeError: module 'urllib' has no attribute 'urlretrieve'

Then you should try following code to fix the issue:

import urllib.request
MyUrl = "www.google.com" #Your url goes here
urllib.request.urlretrieve(MyUrl)

This answer missed one aspect: the OP asked for ALL combinations... not just combinations of length "r".

So you'd either have to loop through all lengths "L":

import itertools

stuff = [1, 2, 3]
for L in range(0, len(stuff)+1):
    for subset in itertools.combinations(stuff, L):
        print(subset)

Or -- if you want to get snazzy (or bend the brain of whoever reads your code after you) -- you can generate the chain of "combinations()" generators, and iterate through that:

from itertools import chain, combinations
def all_subsets(ss):
    return chain(*map(lambda x: combinations(ss, x), range(0, len(ss)+1)))

for subset in all_subsets(stuff):
    print(subset)

If you have the size of the image, why don't you set the frame.size of the image view to be of this size?

EDIT----

Ok, so seeing your comment I propose this:

UIImageView *imageView;
//so let's say you're image view size is set to the maximum size you want

CGFloat maxWidth = imageView.frame.size.width;
CGFloat maxHeight = imageView.frame.size.height;

CGFloat viewRatio = maxWidth / maxHeight;
CGFloat imageRatio = image.size.height / image.size.width;

if (imageRatio > viewRatio) {
    CGFloat imageViewHeight = round(maxWidth * imageRatio);
    imageView.frame = CGRectMake(0, ceil((self.bounds.size.height - imageViewHeight) / 2.f), maxWidth, imageViewHeight);
}
else if (imageRatio < viewRatio) {
    CGFloat imageViewWidth = roundf(maxHeight / imageRatio);
    imageView.frame = CGRectMake(ceil((maxWidth - imageViewWidth) / 2.f), 0, imageViewWidth, maxHeight);
} else {
    //your image view is already at the good size
}

This code will resize your image view to its image ratio, and also position the image view to the same centre as your "default" position.

PS: I hope you're setting imageView.layer.shouldRasterise = YES and imageView.layer.rasterizationScale = [UIScreen mainScreen].scale;

if you're using CALayer shadow effect ;) It will greatly improve the performance of your UI.

HTML: text/html, full-stop.

XHTML: application/xhtml+xml, or only if following HTML compatbility guidelines, text/html. See the W3 Media Types Note.

XML: text/xml, application/xml (RFC 2376).

There are also many other media types based around XML, for example application/rss+xml or image/svg+xml. It's a safe bet that any unrecognised but registered ending in +xml is XML-based. See the IANA list for registered media types ending in +xml.

(For unregistered x- types, all bets are off, but you'd hope +xml would be respected.)

Wrong samples: "MM-dd-yyyy H:mm","MM-dd-yyyy"

Correct sample: "MM-dd-yyyy HH:mm"

Have a look at the mainpage command.

Also, have a look this answer to another thread: How to include custom files in Doxygen. It states that there are three extensions which doxygen classes as additional documentation files: .dox, .txt and .doc. Files with these extensions do not appear in the file index but can be used to include additional information into your final documentation - very useful for documentation that is necessary but that is not really appropriate to include with your source code (for example, an FAQ)

So I would recommend having a mainpage.dox (or similarly named) file in your project directory to introduce you SDK. Note that inside this file you need to put one or more C/C++ style comment blocks.

The default sort is stable, so we sort twice: First by the minor key, then by the major key

rum1 <- rum[order(rum$I2, decreasing = FALSE),]
rum2 <- rum1[order(rum1$I1, decreasing = TRUE),]

There are many examples on working with arrays in C# here.

I hope this helps.

This is my solution :

$(document).ready(function () {
  $( "td" ).on({
    "click": clicked,
    "mouseover": hovered,
    "mouseout": mouseout
});

var flag=0;

function hovered(){
  $(this).css("background", "#380606");
}

function mouseout(){
  if (flag == 0){
  $(this).css("background", "#ffffff");
} else {
  flag=0;
}
}

function clicked(){
  $(this).css("background","#000000");
  flag=1;
}
})

Try:

With the modification of a single line you could alter the fullcalendar.js script to allow a line break and put multiple information on the same line.

In FullCalendar.js on line ~3922 find htmlEscape(s) function and add .replace(/<br\s?/?>/g, '
') to the end of it.

function htmlEscape(s) {
    return s.replace(/&/g, '&')
    .replace(/</g, '&lt;')
    .replace(/>/g, '&gt;')
    .replace(/'/g, '&#039;')
    .replace(/"/g, '&quot;')
    .replace(/\n/g, '<br />')
    .replace(/&lt;br\s?\/?&gt;/g, '<br />');
}

This will allow you to have multiple lines for the title, separating the information. Example replace the event.title with title: 'All Day Event' + '<br />' + 'Other Description'

Description of the possible values:

• left: No floating elements allowed on the left side
• right: No floating elements allowed on the right side
• both: No floating elements allowed on either the left or the right side
• none: Default. Allows floating elements on both sides
• inherit: Specifies that the value of the clear property should be inherited from the parent element

simple just use the img tag helper. Rails knows to look in the images folder in the asset pipeline, you can use it like this

<%= image_tag "image.jpg" %>

I was just looking for this... By using David's answer, I used a span and gave it some padding (height won't work + top margin issue)... Works like a charm;

See fiddle

<ul>
  <li><a href="index.php">Home</a></li><span class="divider"></span>
  <li><a href="about.php">About Us</a></li><span class="divider"></span>
  <li><a href="#">Events</a></li><span class="divider"></span>
  <li><a href="#">Forum</a></li><span class="divider"></span>
  <li><a href="#">Contact</a></li>
</ul>

.divider {
    border-left: 1px solid #8e1537;
    padding: 29px 0 24px 0;
}

str.replace(/\s|[0-9_]|\W|[#$%^&*()]/g, "") I did sth like this. But there is some people who did it much easier like str.replace(/\W_/g,"");

From the JSON standard:

An object is an unordered collection of zero or more name/value pairs, where a name is a string and a value is a string, number, boolean, null, object, or array.

(emphasis mine).

So, no you can't guarantee the order.

There is a comprehensive list of tools on the PostgreSQL Wiki:

https://wiki.postgresql.org/wiki/PostgreSQL_Clients

And of course PostgreSQL itself comes with pgAdmin, a GUI tool for accessing Postgres databases.

Consider using the Restlet framework, which has great semantics for this sort of thing. It's powerful and flexible.

The code could be as simple as:

Client client = new Client(Protocol.HTTP);
Response response = client.get(url);
if (response.getStatus().isError()) {
    // uh oh!
}

In some cases if you delete your Bin and Obj folders will solve this problem.

As static variables are class level variables, they will store " permanent generation " of heap memory. Please look into this for more details of JVM. Hoping this will be helpful

Solution: Launching a Downloadable Link

The following works in all browsers, but as always there are caveats.

Background:

"URL Shortcuts" are OS dependent. The following solution is for MS Windows due to a lack of standards between environments.

If you require linux support for the solution below, please see this article.
* I have no connection to the article, YMMV.

URL shortcuts come in two forms:

1. Files with .URL extensions are text based. Can be dynamically generated.

   [InternetShortcut]
   URL=file:///D:/

2. Files with .LNK extension are binary. They can be generated dynamically, but require iShelLinkInterface implementer. This is complicated by default OS restrictions, which rightfully prevent an IIS process from reaching Shell.

.URL is the recommended solution, as dynamic generation is viable across Web Languages/Frameworks and allows for a KISS implementation.

Overview/Recap:

1. Security restrictions will not allow you to open a path/launch explorer directly from the page (as stated by @Pekka).
2. Sites hosted externally (not on your local computer) will not allow file:///... uri's under default security permissions.

Solution:

Provide a downloadable link (.URL or .LNK) to the resource. Browser behavior will be explained at end of post.

Option 1: Produce a .lnk file and save it to the server. Due to the binary nature of the .LNK file, this is not the recommended solution, but a pre-generated file should be viable.

Option 2: Produce a .url file and either save it to the server or dynamically generate it. In my situation, I am dynamically creating the .URL file.

Solution Details (.URL):

1. Add .url to the available MIME types in your web server.
   
   For IIS open the site, choose MIME Types, and add the following:
   

   File name Extension= .url
   MIME type: application/internet-shortcut

   Per @cremax ... For Webkit Browsers like Chrome on Apache Servers add this code to .htaccess or http.config:

   SetEnvIf Request_URI ".url$" requested_url=url Header add Content-Disposition "attachment" env=requested_url

2. The .url file is a text file formatted as follows (again, this can be dynamically generated).

   File Contents:

   [InternetShortcut]
   URL=file:///D:

3. Provide a link to the script that generates the .url file, or to the file itself.

   If you've simply uploaded a .url file to your server, add the following to your HTML:

   <a href="URIShortcut.url">Round-About Linking</a>

Browser Dependent Behavior

Chrome: Download/Save file.url then open
In Chrome, this behavior can be augmented by choosing the "Always open files of this type" option.

FireFox: Download/Save file.url then open

Internet Explorer: Click “Open” and go straight to directory (no need to save shortcut)

Internet Explorer has the preferred behavior, but Chrome and Firefox are at least serviceable.

I was getting an error despite importing the following,

import nltk
nltk.download()

but for google colab this solved my issue.

   !python3 -c "import nltk; nltk.download('all')"

There are many toolboxes. Since you mentioned one that is commercially available from MathWorks, I assume you mean how do you get a trial/license

http://www.mathworks.com/products/image/

There is a link for trials, purchase, demos. This will get you in touch with your sales representative. If you know your sales representative, you could just call to get attention faster.

If you mean just a general toolbox that is from a source other than MathWorks, I would check with the producer, as it will vary widely from "Put it on your path." to whatever their purchase and licensing procedure is.

To get the names:

for name in vars().keys():
  print(name)

To get the values:

for value in vars().values():
  print(value)

vars() also takes an optional argument to find out which vars are defined within an object itself.

Angular 2.0.0 Final:

I have found that using a ViewChild setter is most reliable way to set the initial form control focus:

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => {
            this._renderer.invokeElementMethod(_input.nativeElement, "focus");
        }, 0);
    }
}

The setter is first called with an undefined value followed by a call with an initialized ElementRef.

Working example and full source here: http://plnkr.co/edit/u0sLLi?p=preview

Using TypeScript 2.0.3 Final/RTM, Angular 2.0.0 Final/RTM, and Chrome 53.0.2785.116 m (64-bit).

UPDATE for Angular 4+

Renderer has been deprecated in favor of Renderer2, but Renderer2 does not have the invokeElementMethod. You will need to access the DOM directly to set the focus as in input.nativeElement.focus().

I'm still finding that the ViewChild setter approach works best. When using AfterViewInit I sometimes get read property 'nativeElement' of undefined error.

@ViewChild("myInput")
set myInput(_input: ElementRef | undefined) {
    if (_input !== undefined) {
        setTimeout(() => { //This setTimeout call may not be necessary anymore.
            _input.nativeElement.focus();
        }, 0);
    }
}

Yes, using Cookies. But be careful, don't put too much in them (I think there is a limit at 4kb). But a few variables are ok.

If you need to store considerably more than that, check out @Annie's great tips in the other answer. For small time data storage, I would say Cookies are the easiest thing.

Note that cookies are stored client side.

Building on the excellent answer above by fir3rpho3nixx and David Schmitt, I have modified their code and added the ShouldInheritOrImplementTypedGenericInterface test (last one).

    /// <summary>
    /// Find out if a child type implements or inherits from the parent type.
    /// The parent type can be an interface or a concrete class, generic or non-generic.
    /// </summary>
    /// <param name="child"></param>
    /// <param name="parent"></param>
    /// <returns></returns>
    public static bool InheritsOrImplements(this Type child, Type parent)
    {
        var currentChild = parent.IsGenericTypeDefinition && child.IsGenericType ? child.GetGenericTypeDefinition() : child;

        while (currentChild != typeof(object))
        {
            if (parent == currentChild || HasAnyInterfaces(parent, currentChild))
                return true;

            currentChild = currentChild.BaseType != null && parent.IsGenericTypeDefinition && currentChild.BaseType.IsGenericType
                                ? currentChild.BaseType.GetGenericTypeDefinition()
                                : currentChild.BaseType;

            if (currentChild == null)
                return false;
        }
        return false;
    }

    private static bool HasAnyInterfaces(Type parent, Type child)
    {
        return child.GetInterfaces().Any(childInterface =>
            {
                var currentInterface = parent.IsGenericTypeDefinition && childInterface.IsGenericType
                    ? childInterface.GetGenericTypeDefinition()
                    : childInterface;

                return currentInterface == parent;
            });

    }

In simple words

$.ajax("info.txt").done(function(data) {
  alert(data);
}).fail(function(data){
  alert("Try again champ!");
});

if its get the info.text then it will alert and whatever function you add or if any how unable to retrieve info.text from the server then alert or error function.

I experienced this after updating to Windows 10 Fall Creators edition version 1709. None of the solutions above worked for me. I was able to fix the error this way:

1. Go to “Control Panel” > “Administrative Tools” > “IIS Manager”.
2. Choose “Change .NET Framework Version” from the “Actions” in the right margin.
3. I chose the latest version shown and clicked “OK”.

If IIS Manager is not available under Administrative Tools, you can enable it this way:

1. Press the Windows key and type "Turn Windows Features On or Off" then select the search result.
2. In dialog that appears, check the box by “Internet Information Services” and click OK.

I figured out the answer to above problem. Below query will return rows which have even a signle occurrence of characters besides alphabets, numbers, square brackets, curly brackets,s pace and dot. Please note that position of closing bracket ']' in matching pattern is important.

Right ']' has the special meaning of ending a character set definition. It wouldn't make any sense to end the set before you specified any members, so the way to indicate a literal right ']' inside square brackets is to put it immediately after the left '[' that starts the set definition

SELECT * FROM test WHERE REGEXP_LIKE(sampletext,  '[^]^A-Z^a-z^0-9^[^.^{^}^ ]' );

It is possible but how depends on what you are trying to accomplish. If it's this:

| Left-aligned       Right-aligned | in one cell then you can use floating divs inside the td tag:

<td>
<div style='float: left; text-align: left'>Left-aligned</div>
<div style='float: right; text-align: right'>Right-aligned</div>
</td>

If it's | Left-aligned
                                           Right Aligned |

Then Balon's solution is correct.

If it's: | Left-aligned    |   Right-Aligned |

Then it's:

<td align="left">Left-aligned</td>
<td align="right">Right-Aligned</td>

The best way which works now on all Major Browsers is the following Script:

(function () {
    var displayOnlineStatus = document.getElementById("online-status"),
        isOnline = function () {
            displayOnlineStatus.innerHTML = "Online";
            displayOnlineStatus.className = "online";
        },
        isOffline = function () {
            displayOnlineStatus.innerHTML = "Offline";
            displayOnlineStatus.className = "offline";
        };

    if (window.addEventListener) {
        /*
            Works well in Firefox and Opera with the 
            Work Offline option in the File menu.
            Pulling the ethernet cable doesn't seem to trigger it.
            Later Google Chrome and Safari seem to trigger it well
        */
        window.addEventListener("online", isOnline, false);
        window.addEventListener("offline", isOffline, false);
    }
    else {
        /*
            Works in IE with the Work Offline option in the 
            File menu and pulling the ethernet cable
        */
        document.body.ononline = isOnline;
        document.body.onoffline = isOffline;
    }
})();

Might help some else - I came here because I missed putting two // after http:. This is what I had:

I think it will be sometime before we get to see access to the NFC as the pure security side of it like for example being able to walk past somebody brush past them and & get your phone to the zap the card details or simply Wave your phone over someone's wallet which They left on the desk.

I think the first step is for Apple to talk to banks and find more ways of securing cards and NFC before This will be allowed

pattern="foo"
for _dir in *"${pattern}"*; do
    [ -d "${_dir}" ] && dir="${_dir}" && break
done
echo "${dir}"

This is better than the other shell solution provided because

• it will be faster for huge directories as the pattern is part of the glob and not checked inside the loop
• actually works as expected when there is no directory matching your pattern (then ${dir} will be empty)
• it will work in any POSIX-compliant shell since it does not rely on the =~ operator (if you need this depends on your pattern)
• it will work for directories containing newlines in their name (vs. find)

There is no rule to achieve that using CSS only, besides the object-fit (that you are currently using), which has partial support in EDGE¹ so if you want to use this in IE, you have to use a object-fit polyfill in case you want to use just the element img, otherwise you have to do some workarounds.

You can see the the object-fit support here

UPDATE(2019)

You can use a simple JS snippet to detect if the object-fit is supported and then replace the img for a svg

//ES6 version
if ('objectFit' in document.documentElement.style === false) {
    document.addEventListener('DOMContentLoaded', () => {
        document.querySelectorAll('img[data-object-fit]').forEach(image => {
            (image.runtimeStyle || image.style).background = `url("${image.src}") no-repeat 50%/${image.currentStyle ? image.currentStyle['object-fit'] : image.getAttribute('data-object-fit')}`
            image.src = `data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='${image.width}' height='${image.height}'%3E%3C/svg%3E`
        })
    })
}

//ES5 version transpiled from code above with BabelJS
if ('objectFit' in document.documentElement.style === false) {
    document.addEventListener('DOMContentLoaded', function() {
        document.querySelectorAll('img[data-object-fit]').forEach(function(image) {
            (image.runtimeStyle || image.style).background = "url(\"".concat(image.src, "\") no-repeat 50%/").concat(image.currentStyle ? image.currentStyle['object-fit'] : image.getAttribute('data-object-fit'));
            image.src = "data:image/svg+xml,%3Csvg xmlns='http://www.w3.org/2000/svg' width='".concat(image.width, "' height='").concat(image.height, "'%3E%3C/svg%3E");
        });
    });
}

img {
  display: inline-flex;
  width: 175px;
  height: 175px;
  margin-right: 10px;
  border: 1px solid red
}

[data-object-fit='cover'] {
  object-fit: cover
}

[data-object-fit='contain'] {
  object-fit: contain
}

<img data-object-fit='cover' src='//picsum.photos/1200/600' />
<img data-object-fit='contain' src='//picsum.photos/1200/600' />
<img src='//picsum.photos/1200/600' />

UPDATE(2018)

1 - EDGE has now partial support for object-fit since version 16, and by partial, it means only works in img element (future version 18 still has only partial support)

You can do something like this:

$('.notice')
    .fadeIn()
    .animate({opacity: '+=0'}, 2000)   // Does nothing for 2000ms
    .fadeOut('fast');

Sadly, you can't just do .animate({}, 2000) -- I think this is a bug, and will report it.

This problems gave me great headache when i tried to use reverse for generating activation link and send it via email of course. So i think from tests.py it will be same. The correct way to do this is following:

from django.test import Client
from django.core.urlresolvers import reverse

#app name - name of the app where the url is defined
client= Client()
response = client.get(reverse('app_name:edit_project', project_id=4)) 

This is key answer to this post "bLengthChange": false, will hide the Entries Dropdown

In Python 3.5, isinstance(x, date) works to me:

>>> from datetime import date
>>> x = date(2012, 9, 1)
>>> type(x)
<class 'datetime.date'>
>>> isinstance(x, date)
True
>>> type(x) is date
True

for decreasing order for integer array of 2 dimension you can use

Arrays.sort(contests, (a, b) -> Integer.compare(b[0],a[0]));//decreasing order

Arrays.sort(contests, (a, b) -> Integer.compare(a[0],b[0]);//decreasing order

Have you tried just changing the port number of MySQL and see if it works?

1. Right click your WAMP icon

2. Choose MySQL, in the menu choose "Use a port other than 3306"

3. Change port number to be "3307"

1. You can create pipe inherited from PipeTransform base
2. Then implement transform method

Used in Angular 4 - it's working. Best way to format a date is a pipe.

Create your custom pipe like this:

import { Pipe, PipeTransform} from '@angular/core';
import { DatePipe } from '@angular/common';

@Pipe({
    name: 'dateFormat'
  })
  export class DateFormatPipe extends DatePipe implements PipeTransform {
    transform(value: any, args?: any): any {
       ///MMM/dd/yyyy 
       return super.transform(value, "MMM/dd/yyyy");
    }
  }

and it's used in a TypeScript class like this:

////my class////

export class MyComponent
{
  constructor(private _dateFormatPipe:DateFormatPipe)
  {
  }

  formatHereDate()
  {
     let myDate = this._dateFormatPipe.transform(new Date())//formatting current ///date here 
     //you can pass any date type variable 
  }
}

work for me mysql select * from (SELECT number,max(date_added) as datea FROM sms_chat group by number) as sup order by datea desc

We wrote a wrapper class that captures the buffer and converts the printed output to an exception. this lets us upgrade the phpmailer file without having to remember to comment out the echo statements each time we upgrade.

The wrapper class has methods something along the lines of:

public function AddAddress($email, $name = null) {
    ob_start();
    parent::AddAddress($email, $name);
    $error = ob_get_contents();
    ob_end_clean();
    if( !empty($error) ) {
        throw new Exception($error);
    }
}

namedtuples are immutable, just like standard tuples. You have two choices:

1. Use a different data structure, e.g. a class (or just a dictionary); or
2. Instead of updating the structure, replace it.

The former would look like:

class N(object):

    def __init__(self, ind, set, v):
        self.ind = ind
        self.set = set
        self.v = v

And the latter:

item = items[node.ind]
items[node.ind] = N(item.ind, item.set, node.v)

Edit: if you want the latter, Ignacio's answer does the same thing more neatly using baked-in functionality.

Manually deleting the old assembly from folder location and then adding the reference to new assemblies might help.

Hi a small correction in the above script.. above script skipping the first character when displaying the output.

function stripSlashes(x)
{
var y = "";
for(i = 0; i < x.length; i++)
{
    if(x.charAt(i) == "/")
    {
        y += "";
    }
    else
    {
        y+= x.charAt(i);
    }
}
return y;   
}

I think a 2 step approach is best, because c 2-d arrays are just and array of arrays. The first step is to allocate a single array, then loop through it allocating arrays for each column as you go. This article gives good detail.

I followed https://www.mysysadmintips.com/windows/clients/761-move-android-studio-avd-folder-to-a-new-location.

1. Start copying a folder "C:\Users\user\.android\avd" to "D:\Android\.android\avd" (or something else).

2. Close Android Studio and running emulators.

3. Press Win + Break and open Advanced System Settings. Then press Environment Variables. Add a user variable ANDROID_SDK_HOME. (I didn't experiment with ANDROID_AVD_HOME.) In Variable value field write D:\Android. If you also moved SDK to another folder, change ANDROID_HOME (I forgot to change it and some emulators didn't launch, see https://stackoverflow.com/a/57408085/2914140).

4. Wait until the folder will finish copying and start Android Studio.

5. Open Android Virtual Device Manager and see a list of emulators. If you don't see emulators and they existed, then probably you entered wrong path into user variable value in step 3. In this case close AS, change the variable and open AS again.

6. Start any emulator. It will try to restore it's state, but it sometimes fails. A black screen can appear instead of Android wallpaper.

7. In this case you can:

   a. Restart your emulator. To do this close running emulator, then in AVD Manager click Cold Boot Now.

b. If this didn't help, open emulator settings, found in file "D:\Android\.android\avd\Pixel_API_27.ini".

Change a path to a new AVD folder. Restart the emulator.

8. Delete old AVD folder from "C:\Users\user\.android\avd".

Given Enum1 value = ..., then if you mean by name:

Enum2 value2 = (Enum2) Enum.Parse(typeof(Enum2), value.ToString());

If you mean by numeric value, you can usually just cast:

Enum2 value2 = (Enum2)value;

(with the cast, you might want to use Enum.IsDefined to check for valid values, though)

As user 'Skip Head' already pointed out, csv or a any table file format would be a better fitt in your case.

If it is an option for you, maybe this Table implementation might interest you.

Well, for your sample and any with a limited number of unique columns, this should do it.

select 
    distinct a,
    (select distinct t2.b  from t t2  where t1.a=t2.a and t2.b='VIEW'),
    (select distinct t2.b from t t2  where t1.a=t2.a and t2.b='EDIT')
from t t1

One can use margin in order to change the width of a line and place it center.

<View style = {styles.lineStyle} />

const styles = StyleSheet.create({
  lineStyle:{
        borderWidth: 0.5,
        borderColor:'black',
        margin:10,
   }
 });

if you want to give margin dynamically then you can use Dimension width.

Found an XML transform stylesheet here (wayback machine link, site itself is in german)

The stylesheet added here could be helpful:

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="iso-8859-1"/>

<xsl:strip-space elements="*" />

<xsl:template match="/*/child::*">
<xsl:for-each select="child::*">
<xsl:if test="position() != last()">"<xsl:value-of select="normalize-space(.)"/>",    </xsl:if>
<xsl:if test="position()  = last()">"<xsl:value-of select="normalize-space(.)"/>"<xsl:text>&#xD;</xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:template>

</xsl:stylesheet>

Perhaps you want to remove the quotes inside the xsl:if tags so it doesn't put your values into quotes, depending on where you want to use the CSV file.

The example above showing the import with ...sun.com/jsp/jstl/format is incorrect (meaning it didn't work for me).

Instead try the below -this import statement is valid

<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %><%@ taglib uri="http://java.sun.com/jstl/core-rt" prefix="c-rt" %><%@ taglib uri="http://java.sun.com/jstl/fmt" prefix="fmt" %>
<html>
  <head>
    <title>Format Date</title>
  </head>

  <body>
    <c-rt:set var="now" value="<%=new java.util.Date()%>" />

    <table border="1" cellpadding="0" cellspacing="0"
    style="border-collapse: collapse" bordercolor="#111111"
    width="63%" id="AutoNumber2">
      <tr>
        <td width="100%" colspan="2" bgcolor="#0000FF">
          <p align="center">
            <b>
              <font color="#FFFFFF" size="4">Formatting: 
              <fmt:formatDate value="${now}" type="both"
              timeStyle="long" dateStyle="long" />
              </font>
            </b>
          </p>
        </td>
      </tr>

Try onclick function separately it can give you access to execute your function which can be used to open up a new window, for this purpose you first need to create a javascript function there you can define it and in your anchor tag you just need to call your function.

Example:

function newwin() {              
 myWindow=window.open('lead_data.php?leadid=1','myWin','width=400,height=650')
}

See how to call it from your anchor tag

<a onclick='newwin()'>Anchor</a>

May be this will help you a lot to understand your problem.

Looks like your problem is that you are trying to run python test.py from within the Python interpreter, which is why you're seeing that traceback.

Make sure you're out of the interpreter, then run the python test.py command from bash or command prompt or whatever.

Just in case that the remote file needs your credential to get accessed, you can generate a System.Net.WebClient object using cmdlet New-Object to "Copy File Remotely", like so

$Source = "\\192.168.x.x\somefile.txt"
$Dest   = "C:\Users\user\somefile.txt"
$Username = "username"
$Password = "password"

$WebClient = New-Object System.Net.WebClient
$WebClient.Credentials = New-Object System.Net.NetworkCredential($Username, $Password)

$WebClient.DownloadFile($Source, $Dest)

Or if you need to upload a file, you can use UploadFile:

$Dest = "\\192.168.x.x\somefile.txt"
$Source   = "C:\Users\user\somefile.txt"

$WebClient.UploadFile($Dest, $Source)

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

As indicated in other answers, System.getProperty provides the raw data. However, the Apache Commons Lang component provides a wrapper for java.lang.System with handy properties like SystemUtils.IS_OS_WINDOWS, much like the aforementioned Swingx OS util.

There is an open source Javascript library that offers something related : mobile-bookmark-bubble

The Mobile Bookmark Bubble is a JavaScript library that adds a promo bubble to the bottom of your mobile web application, inviting users to bookmark the app to their device's home screen. The library uses HTML5 local storage to track whether the promo has been displayed already, to avoid constantly nagging users.

The current implementation of this library specifically targets Mobile Safari, the web browser used on iPhone and iPad devices.

It's a simplifications but very easy... You need to add the the focusable flag to the checkbox, as written before. You need also to add the clickable flag, as shown here:

android:focusable="false"
android:clickable="false"

Than you control the checkbox state from within the ListView (ListFragment in my case) onListItemClick event.

This the sample onListItemClick method:

public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
//Get related checkbox and change flag status..
CheckBox cb = (CheckBox)v.findViewById(R.id.rowDone);
cb.setChecked(!cb.isChecked());
Toast.makeText(getActivity(), "Click item", Toast.LENGTH_SHORT).show();
}

The obvious way would be to call the function like this

print(string("Yo!"));

This article describes various options for accessing SharePoint content. You have a choice between REST and CSOM. I'd try CSOM if possible. File upload / download specifically is nicely described in this article.

Overall notes:

    //First construct client context, the object which will be responsible for
    //communication with SharePoint:
    var context = new ClientContext(@"http://site.absolute.url")

    //then get a hold of the list item you want to download, for example
    var list = context.Web.Lists.GetByTitle("Pipeline");
    var query = CamlQuery.CreateAllItemsQuery(10000);
    var result = list.GetItems(query);

    //note that data has not been loaded yet. In order to load the data
    //you need to tell SharePoint client what you want to download:

    context.Load(result, items=>items.Include(
        item => item["Title"],
        item => item["FileRef"]
    ));

    //now you get the data
    context.ExecuteQuery();

    //here you have list items, but not their content (files). To download file
    //you'll have to do something like this:

    var item = items.First();

    //get the URL of the file you want:
    var fileRef = item["FileRef"];

    //get the file contents:
    FileInformation fileInfo = File.OpenBinaryDirect(context, fileRef.ToString());

    using (var memory = new MemoryStream())
    {
          byte[] buffer = new byte[1024 * 64];
          int nread = 0;
          while ((nread = fileInfo.Stream.Read(buffer, 0, buffer.Length)) > 0)
          {
              memory.Write(buffer, 0, nread);
          }
          memory.Seek(0, SeekOrigin.Begin);
          // ... here you have the contents of your file in memory, 
          // do whatever you want
    }

Avoid working with the stream directly, read it into the memory first. Network-bound streams are not necessarily supporting stream operations, not to mention performance. So, if you are reading a pic from that stream or parsing a document, you may end up with some unexpected behavior.

On a side note, I have a related question re: performance of this code above, as you are taking some penalty with every file request. See here. And yes, you need 4.5 full .NET profile for this.

I wrote an alternative solution how to make any element focusable and "blurable".

It's based on making an element as contentEditable and hiding visually it and disabling edit mode itself:

el.addEventListener("keydown", function(e) {
  e.preventDefault();
  e.stopPropagation();
});

el.addEventListener("blur", cbBlur);
el.contentEditable = true;

DEMO

Note: Tested in Chrome, Firefox, and Safari (OS X). Not sure about IE.

Related: I was searching for a solution for VueJs, so for those who interested/curious how to implement such functionality using Vue Focusable directive, please take a look.

Try this

Objective C

  [TableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];

  [TableView setSeparatorColor:[UIColor colorWithPatternImage:[UIImage imageNamed:@"[email protected]"]]];

Swift

    tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine
    tableView.separatorColor = UIColor(patternImage: UIImage(named: "YOUR_IMAGE_NAME")!)

You can use BETWEEN:

DELETE FROM table
where id between 163 and 265

1)Yes it is, when there is style then it is styling your code(css).2) is belong to html it is like a container that keep your css.

Even Simpler than Meagar's answer

overwrite touchesBegan:withEvent:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    [textField resignFirstResponder];`
}

This will dismiss the keyboardwhen you touch anywhere in the background.

This will loop through all cells in a given range that you define ("RANGE TO SEARCH") and add dashes at the cell below using the Offset() method. As a best practice in VBA, you should never use the Select method.

Sub AddDashes()

Dim SrchRng As Range, cel As Range

Set SrchRng = Range("RANGE TO SEARCH")

For Each cel In SrchRng
    If InStr(1, cel.Value, "TOTAL") > 0 Then
        cel.Offset(1, 0).Value = "-"
    End If
Next cel

End Sub

Try to use appendChild method:

select.appendChild(option);

My reputation being too small to comment an answer, here is my feedback concerning roquen answer (using settings on xmlwriter to force the stream to close): it works perfectly and it made me save a lot of time. roquen's example requires some adjustment, here is the code that works on .NET framework 4.8 :

    XmlWriterSettings settings = new XmlWriterSettings();
    settings.CloseOutput = true;
    writer = XmlWriter.Create(stream, settings);

import React, { useEffect } from 'react';
import { useLocation } from 'react-router';

function MyApp() {

  const location = useLocation();

  useEffect(() => {
      console.log('route has been changed');
      ...your code
  },[location.pathname]);

}

with hooks

If you are on a mac keyboard using with UNIX OS;

control + alt + command + left or right should work for sure.

A shorter way to write the condition:

WHERE some_col > ''

Since null > '' produces unknown, this has the effect of filtering out both null and empty strings.

Suppose that you have a file Called "test.txt" with:

a=1.251
b=2.65415
c=3.54
d=549.5645
e=4684.65489

And you want to find a variable (a,b,c,d or e):

ffile=open('test.txt','r').read()

variable=raw_input('Wich is the variable you are looking for?\n')

ini=ffile.find(variable)+(len(variable)+1)
rest=ffile[ini:]
search_enter=rest.find('\n')
number=float(rest[:search_enter])

print "value:",number

You may want to try:

for (int i=0; i < 2; i++)
{
      Toast.makeText(this, "blah", Toast.LENGTH_LONG).show();
}

to double the time. If you specify 3 instead the 2 it will triple the time..etc.

ifconfig -a
ip -d link
ls -l /sys/class/net/ (physical and virtual devices)
route -n

If you want the output of (ifconfig -a) in json format you can use this (python)

If someone has the same issue as I had - make sure that you don't install from the Ubuntu 14.04 repo onto a 12.04 machine - it gives this same error. Reinstalling from the proper repository fixed the issue.

How to install Python from source without libffi in /usr/local?

Andy's Blog Article

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError
