The 'code between' is an example of the Head-Tail pattern.

You have an item, which is followed by a sequence of ( between, item ) pairs. You can also view this as a sequence of (item, between) pairs followed by an item. It's generally simpler to take the first element as special and all the others as the "standard" case.

Further, to avoid repeating code, you have to provide a function or other object to contain the code you don't want to repeat. Embedding an if statement in a loop which is always false except one time is kind of silly.

def item_processing( item ):
    # *the common processing*

head_tail_iter = iter( someSequence )
head = next(head_tail_iter)
item_processing( head )
for item in head_tail_iter:
    # *the between processing*
    item_processing( item )

This is more reliable because it's slightly easier to prove, It doesn't create an extra data structure (i.e., a copy of a list) and doesn't require a lot of wasted execution of an if condition which is always false except once.

The answer is in the error message. In the past you or a process did a sudo pip and that caused some of the directories under /Library/Python/2.7/site-packages/... to have permissions that make it unaccessable to your current user.

Then you did a pip install whatever which relies on the other thing.

So to fix it, visit the /Library/Python/2.7/site-packages/... and find the directory with the root or not-your-user permissions and either remove then reinstall those packages, or just force ownership to the user to whom ought to have access.

hope it will work

 @Html.DropDownList("accountid", (IEnumerable<SelectListItem>)ViewBag.Accounts, String.Empty, new { @class ="extra-class" })

Here String.Empty will be the empty as a default selector.

You can get the path programmatically:

using System.Configuration;  // Add a reference to System.Configuration.dll
...
var path = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.PerUserRoamingAndLocal).FilePath;

 <input style="display:none" id="__pageLoaded" value=""/>


 $(document).ready(function () {
        if ($("#__pageLoaded").val() != 1) {

            $("#__pageLoaded").val(1);


        } else {
            shared.isBackLoad = true;
            $("#__pageLoaded").val(1);  

            // Call any function that handles your back event

        }
    });

The above code worked for me. On mobile browsers, when the user clicked on the back button, we wanted to restore the page state as per his previous visit.

Create an empty folder and move the .mdb file to that folder. And try opening it from there. I tried it this way and it worked for me.

You could call this function for each of the edit texts:

public boolean isEmpty(EditText editText) {
    boolean isEmptyResult = false;
    if (editText.getText().length() == 0) {
        isEmptyResult = true;
    }
    return isEmptyResult;
}

I think the most elegant way to do that is to use the javascript Object.keys like this (I had first implemented a pipe for that but for me, it just complicated my work unnecessary):

in the Component pass Object to template:

Object = Object;

then in the template:

<div *ngFor="let key of Object.keys(objs)">
   my key: {{key}}
   my object {{objs[key] | json}} <!-- hier I could use ngFor again with Object.keys(objs[key]) -->
</div>

If you have a lot of subobjects you should create a component that will print the object for you. By printing the values and keys as you want and on an subobject calling itselfe recursively.

Hier you can find an stackblitz demo for both methods.

Any of the following will work:

s = "true"

(s == 'true').real
1

(s == 'false').real
0

(s == 'true').conjugate()    
1

(s == '').conjugate()
0

(s == 'true').__int__()
1

(s == 'opal').__int__()    
0


def as_int(s):
    return (s == 'true').__int__()

>>>> as_int('false')
0
>>>> as_int('true')
1

Can you be a little more specific? If you're trying to get the HTML inside of a tag you can do something like this:

HTML snippet:

<p><b>This is some text</b></p>

jQuery:

var txt = $('p').html(); // Value of text is <b>This is some text</b>

What you have is a string representing a JSON serialized javascript object. You need to deserialize it back a javascript object before being able to loop through its properties. Otherwise you will be looping through each individual character of this string.

var resultJSON = '{ "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" }';
    var result = $.parseJSON(resultJSON);
    $.each(result, function(k, v) {
        //display the key and value pair
        alert(k + ' is ' + v);
    });

or simply:

arr.forEach(function (val, index, theArray) {
    //do stuff
});

solution - 1) Make sure you're in the root folder of your app. eg app/db/schema.sql.

solution - 2) open/reveal the folder on your window and drag&&drop in the command line next to keywork source (space) filesource. eg source User/myMAC/app/db/schema.sql

Here in simpler words:

DOM

• Tree model parser (Object based) (Tree of nodes).

• DOM loads the file into the memory and then parse- the file.

• Has memory constraints since it loads the whole XML file before parsing.

• DOM is read and write (can insert or delete nodes).

• If the XML content is small, then prefer DOM parser.

• Backward and forward search is possible for searching the tags and evaluation of the information inside the tags. So this gives the ease of navigation.

• Slower at run time.

SAX

• Event based parser (Sequence of events).

• SAX parses the file as it reads it, i.e. parses node by node.

• No memory constraints as it does not store the XML content in the memory.

• SAX is read only i.e. can’t insert or delete the node.

• Use SAX parser when memory content is large.

• SAX reads the XML file from top to bottom and backward navigation is not possible.

• Faster at run time.

To find duplicate counts use below command as requested by you :

sort filename | uniq -c | awk '{print $2, $1}'

I did this in the web.config file. I added to Sobhan's answer, thanks btw.

<connectionStrings>
    <add name="listdb" connectionString="Data Source=|DataDirectory|\db\listdb.sdf"/>
  </connectionStrings>

Where "db" becomes my database directory instead of "App_Data" directory.

And opened normally with:

var db = Database.Open("listdb");

As mentioned in the excellent answer by janoside, you need to construct the JSON string and set it as a StringEntity.

To construct the JSON string, you can use any library or method you are comfortable with. Jackson library is one easy example:

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ObjectNode;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;

ObjectMapper mapper = new ObjectMapper();
ObjectNode node = mapper.createObjectNode();
node.put("name", "value"); // repeat as needed
String JSON_STRING = node.toString();
postMethod.setEntity(new StringEntity(JSON_STRING, ContentType.APPLICATION_JSON));

There's a discussion here that might be useful.

From my own (limited) exposure, I'd say that shoes was the most fun and probably the "easiest" to get into. Be warned, however, that figuring out what was wrong when something breaks can be tricky (at least, it was for me).

For a real-world application that I was planning to deploy to real-world users, I think I'd go with wxruby.

Whenever you create child class object then that object has all the features of parent class. Here Super() is the facilty for accession parent.

If you write super() at that time parents's default constructor is called. same if you write super.

this keyword refers the current object same as super key word facilty for accessing parents.

The recommended way in Python 3.5 and above is to use subprocess.run():

from subprocess import run
output = run("pwd", capture_output=True).stdout

Some times on the emulator, I have to launch the browser before my app can access the Internet.

Here are screenshots for SQL Server 2008 R2, using SSRS Report Designer in Visual Studio 2010.

I have done screenshots as some of the dialogs are not easy to find.

1: Add the group

2: Specify the field you want to group on

3: Now click on the group in the 'Row Groups' selector, directly below the report designer

4: F4 to select property pane; expand 'Group' and set Group > PageBreak > BreakLocation = 'Between', then enter the expression you want for Group > PageName

5: Here is an example expression

Here is the result of the report exported to Excel, with tabs named according to the PageName expression

Creating dataframe from dictionary object.

import pandas as pd
data = [{'name': 'vikash', 'age': 27}, {'name': 'Satyam', 'age': 14}]
df = pd.DataFrame.from_dict(data, orient='columns')

df
Out[4]:
   age  name
0   27  vikash
1   14  Satyam

If you have nested columns then you first need to normalize the data:

data = [
  {
    'name': {
      'first': 'vikash',
      'last': 'singh'
    },
    'age': 27
  },
  {
    'name': {
      'first': 'satyam',
      'last': 'singh'
    },
    'age': 14
  }
]

df = pd.DataFrame.from_dict(pd.json_normalize(data), orient='columns')

df    
Out[8]:
age name.first  name.last
0   27  vikash  singh
1   14  satyam  singh

Source:

• pandas.DataFrame.from_dict
• pandas.json_normalize

The clearest way would be to explicitly set i. For example:

i = 0
while i < 100:
    i += 1
    try:
        # do stuff

    except MyException:
        continue

It is possible. It always seems like a good idea at the time but afterwards it becomes a maintenance nightmare. Your code become littered with pieces of code tying everything together. A new programmer will have lots of problems reading and understanding the code if you use function pointers since it will not be obvious what functions is called.

Data hiding with get/set functions is easy to implement in C but stop there. I have seen multiple attempts at this in the embedded environment and in the end it is always a maintenance problem.

Since you all ready have maintenance issues I would steer clear.

Use a collection of some sort - this will make the code more readable and hide away all those constants. A simple way would be with a list:

// Declared with constants
private static List<Integer> myConstants = new ArrayList<Integer>(){{
    add(12);
    add(16);
    add(19);
}};

// Wherever you are checking for presence of the constant
if(myConstants.contains(x)){
    // ETC
}

As Bohemian points out the list of constants can be static so it's accessible in more than one place.

For anyone interested, the list in my example is using double brace initialization. Since I ran into it recently I've found it nice for writing quick & dirty list initializations.

If you are planning to use appending more then once, you might want to write a function:

//Append text to input element
function jQ_append(id_of_input, text){
    var input_id = '#'+id_of_input;
    $(input_id).val($(input_id).val() + text);
}

After you can just call it:

jQ_append('my_input_id', 'add this text');

Another possible solution that we can use 2 HTML element to store brief and complete text. Hence we can show/hide appropriate HTML element :-)

<p class="content_description" id="brief_description" style="display: block;"> blah blah blah blah blah  </p><p class="content_description" id="complete_description" style="display: none;"> blah blah blah blah blah with complete text </p>

/* jQuery code to toggle both paragraph. */

(function(){
        $('#toggle_content').on(
                'click', function(){
                                $("#complete_description").toggle();
                                $("#brief_description").toggle();
                                if ($("#complete_description").css("display") == "none") {
                                    $(this).text('More...');
                                }   else{
                                    $(this).text('Less...');
                                }
                        }
                );
    })();

Checksum that Matt recommended is probably a better approach to compare columns rather than comparing each column

You can create a method that looks like this:

  public static DataTable SelectedColumns(DataTable RecordDT_, string col1, string col2)
    {
        DataTable TempTable = RecordDT_;

        System.Data.DataView view = new System.Data.DataView(TempTable);
        System.Data.DataTable selected = view.ToTable("Selected", false, col1, col2);
        return selected;
    }

You can return as many columns as possible.. just add the columns as call parameters as shown below:

public DataTable SelectedColumns(DataTable RecordDT_, string col1, string col2,string col3,...)

and also add the parameters to this line:

System.Data.DataTable selected = view.ToTable("Selected", false,col1, col2,col3,...);

Then simply implement the function as:

 DataTable myselectedColumnTable=SelectedColumns(OriginalTable,"Col1","Col2",...);

Thanks...

This post has a method to achieve this

from (zvrba) You can do it by redirecting the output to a file first. For example:

echo zz > bla.txt
set /p VV=<bla.txt
echo %VV%

Have a look at SciPy cookbook. It should give you an idea of some basic methods to import /export data.

If you save/load the files from your own Python programs, you may also want to consider the Pickle module, or cPickle.

For code readability reasons I believe returning true/false should:

• be on one line
• be one command
• be easy to remember
• mention the keyword return followed by another keyword (true or false)

My solution is return $(true) or return $(false) as shown:

is_directory()
{
    if [ -d "${1}" ]; then
        return $(true)
    else
        return $(false)
    fi
}

This cannot be done with the native javascript dialog box, but a lot of javascript libraries include more flexible dialogs. You can use something like jQuery UI's dialog box for this.

I think there is a lot of confusion about which weights are used for what. I am not sure I know precisely what bothers you so I am going to cover different topics, bear with me ;).

Class weights

The weights from the class_weight parameter are used to train the classifier. They are not used in the calculation of any of the metrics you are using: with different class weights, the numbers will be different simply because the classifier is different.

Basically in every scikit-learn classifier, the class weights are used to tell your model how important a class is. That means that during the training, the classifier will make extra efforts to classify properly the classes with high weights.
How they do that is algorithm-specific. If you want details about how it works for SVC and the doc does not make sense to you, feel free to mention it.

The metrics

Once you have a classifier, you want to know how well it is performing. Here you can use the metrics you mentioned: accuracy, recall_score, f1_score...

Usually when the class distribution is unbalanced, accuracy is considered a poor choice as it gives high scores to models which just predict the most frequent class.

I will not detail all these metrics but note that, with the exception of accuracy, they are naturally applied at the class level: as you can see in this print of a classification report they are defined for each class. They rely on concepts such as true positives or false negative that require defining which class is the positive one.

             precision    recall  f1-score   support

          0       0.65      1.00      0.79        17
          1       0.57      0.75      0.65        16
          2       0.33      0.06      0.10        17
avg / total       0.52      0.60      0.51        50

The warning

F1 score:/usr/local/lib/python2.7/site-packages/sklearn/metrics/classification.py:676: DeprecationWarning: The 
default `weighted` averaging is deprecated, and from version 0.18, 
use of precision, recall or F-score with multiclass or multilabel data  
or pos_label=None will result in an exception. Please set an explicit 
value for `average`, one of (None, 'micro', 'macro', 'weighted', 
'samples'). In cross validation use, for instance, 
scoring="f1_weighted" instead of scoring="f1".

You get this warning because you are using the f1-score, recall and precision without defining how they should be computed! The question could be rephrased: from the above classification report, how do you output one global number for the f1-score? You could:

1. Take the average of the f1-score for each class: that's the avg / total result above. It's also called macro averaging.
2. Compute the f1-score using the global count of true positives / false negatives, etc. (you sum the number of true positives / false negatives for each class). Aka micro averaging.
3. Compute a weighted average of the f1-score. Using 'weighted' in scikit-learn will weigh the f1-score by the support of the class: the more elements a class has, the more important the f1-score for this class in the computation.

These are 3 of the options in scikit-learn, the warning is there to say you have to pick one. So you have to specify an average argument for the score method.

Which one you choose is up to how you want to measure the performance of the classifier: for instance macro-averaging does not take class imbalance into account and the f1-score of class 1 will be just as important as the f1-score of class 5. If you use weighted averaging however you'll get more importance for the class 5.

The whole argument specification in these metrics is not super-clear in scikit-learn right now, it will get better in version 0.18 according to the docs. They are removing some non-obvious standard behavior and they are issuing warnings so that developers notice it.

Computing scores

Last thing I want to mention (feel free to skip it if you're aware of it) is that scores are only meaningful if they are computed on data that the classifier has never seen. This is extremely important as any score you get on data that was used in fitting the classifier is completely irrelevant.

Here's a way to do it using StratifiedShuffleSplit, which gives you a random splits of your data (after shuffling) that preserve the label distribution.

from sklearn.datasets import make_classification
from sklearn.cross_validation import StratifiedShuffleSplit
from sklearn.metrics import accuracy_score, f1_score, precision_score, recall_score, classification_report, confusion_matrix

# We use a utility to generate artificial classification data.
X, y = make_classification(n_samples=100, n_informative=10, n_classes=3)
sss = StratifiedShuffleSplit(y, n_iter=1, test_size=0.5, random_state=0)
for train_idx, test_idx in sss:
    X_train, X_test, y_train, y_test = X[train_idx], X[test_idx], y[train_idx], y[test_idx]
    svc.fit(X_train, y_train)
    y_pred = svc.predict(X_test)
    print(f1_score(y_test, y_pred, average="macro"))
    print(precision_score(y_test, y_pred, average="macro"))
    print(recall_score(y_test, y_pred, average="macro"))    

Hope this helps.

Web applications are dynamic websites.

According to wikipedia, website is the abstract term of this paradigm.

A website, also written as web site, or simply site, is a set of related web pages typically served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet or a private local area network through an Internet address known as a uniform resource locator (URL). All publicly accessible websites collectively constitute the World Wide Web. (Source: http://en.wikipedia.org/wiki/Website)

Therefore, the Web Application is a type of website regardless of its purpose, in fact, a dynamic website, but the website is not indeed a web application.

In my point of view, all modern websites are web applications, including CMS's. Does anyone in the world still writes manual static html files, I don't think so. Even though, some websites have few static pages, but if they were created dynamically via a CMS, then it is definitely a CMS web application.

I had a similar problem while trying to add a variable to an object returned from an API. I was iterating through the data with a foreach loop.

foreach ( $results as $data ) {
    $data->direction = 0;
}

This threw the "Creating default object from empty value" Exception in Laravel.

I fixed it with a very small change.

foreach ( $results as &$data ) {
    $data->direction = 0;
}

By simply making $data a reference.

I hope that helps somebody a it was annoying the hell out of me!

Try this, works!

For people using Google Cloud Platform, any error will stop the import process. Personally I encountered two different errors depending on the pg_dump command I issued :

1- The input is a PostgreSQL custom-format dump. Use the pg_restore command-line client to restore this dump to a database.

Occurs when you've tried to dump your DB in a non plain text format. I.e when the command lacks the -Fp or --format=plain parameter. However, if you add it to your command, you may then encounter the following error :

2- SET SET SET SET SET SET CREATE EXTENSION ERROR: must be owner of extension plpgsql

This is a permission issue I have been unable to fix using the command provided in the GCP docs, the tips from this current thread, or following advice from Google Postgres team here. Which recommended to issue the following command :

pg_dump -Fp --no-acl --no-owner -U myusername myDBName > mydump.sql

The only thing that did the trick in my case was manually editing the dump file and commenting out all commands relating to plpgsql.

I hope this helps GCP-reliant souls.

Update :

It's easier to dump the file commenting out extensions, especially since some dumps can be huge : pg_dump ... | grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' > mydump.sql

Which can be narrowed down to plpgsql : pg_dump ... | grep -v -E '(CREATE\ EXTENSION\ IF\ NOT\ EXISTS\ plpgsql|COMMENT\ ON\ EXTENSION\ plpgsql)' > mydump.sql

The question was answered perfectly by Darin Dimitrov, but since ASP.NET 4.5, there is now a better way to set up these bindings to replace* Eval() and Bind(), taking advantage of the strongly-typed bindings.

*Note: this will only work if you're not using a SqlDataSource or an anonymous object. It requires a Strongly-typed object (from an EF model or any other class).

This code snippet shows how Eval and Bind would be used for a ListView control (InsertItem needs Bind, as explained by Darin Dimitrov above, and ItemTemplate is read-only (hence they're labels), so just needs an Eval):

<asp:ListView ID="ListView1" runat="server" DataKeyNames="Id" InsertItemPosition="LastItem" SelectMethod="ListView1_GetData" InsertMethod="ListView1_InsertItem" DeleteMethod="ListView1_DeleteItem">
    <InsertItemTemplate>
        <li>
            Title: <asp:TextBox ID="Title" runat="server" Text='<%# Bind("Title") %>'/><br />         
            Description: <asp:TextBox ID="Description" runat="server" TextMode="MultiLine" Text='<%# Bind("Description") %>' /><br />        
            <asp:Button ID="InsertButton" runat="server" Text="Insert" CommandName="Insert" />        
        </li>
    </InsertItemTemplate>
    <ItemTemplate>
        <li>
            Title: <asp:Label ID="Title" runat="server" Text='<%#  Eval("Title") %>' /><br />
            Description: <asp:Label ID="Description" runat="server" Text='<%# Eval("Description") %>' /><br />        
            <asp:Button ID="DeleteButton" runat="server" Text="Delete" CommandName="Delete" CausesValidation="false"/>
        </li>
      </ItemTemplate>

From ASP.NET 4.5+, data-bound controls have been extended with a new property ItemType, which points to the type of object you're assigning to its data source.

<asp:ListView ItemType="Picture" ID="ListView1" runat="server" ...>

Picture is the strongly type object (from EF model). We then replace:

Bind(property) -> BindItem.property
Eval(property) -> Item.property

So this:

<%# Bind("Title") %>      
<%# Bind("Description") %>         
<%#  Eval("Title") %> 
<%# Eval("Description") %>

Would become this:

<%# BindItem.Title %>         
<%# BindItem.Description %>
<%# Item.Title %>
<%# Item.Description %>

Advantages over Eval & Bind:

• IntelliSense can find the correct property of the object your're working with
• If property is renamed/deleted, you will get an error before page is viewed in browser
• External tools (requires full versions of VS) will correctly rename item in markup when you rename a property on your object

import java.util.Random;

public class passGen{
    // Version 1.0
    private static final String dCase = "abcdefghijklmnopqrstuvwxyz";
    private static final String uCase = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    private static final String sChar = "!@#$%^&*";
    private static final String intChar = "0123456789";
    private static Random r = new Random();
    private static StringBuilder pass = new StringBuilder();

    public static void main (String[] args) {
        System.out.println ("Generating pass...");
        while (pass.length () != 16){
            int rPick = r.nextInt(4);
            if (rPick == 0){
                int spot = r.nextInt(26);
                pass.append(dCase.charAt(spot));
            } else if (rPick == 1) {
                int spot = r.nextInt(26);
                pass.append(uCase.charAt(spot));
            } else if (rPick == 2) {
                int spot = r.nextInt(8);
                pass.append(sChar.charAt(spot));
            } else {
                int spot = r.nextInt(10);
                pass.append(intChar.charAt(spot));
            }
        }
        System.out.println ("Generated Pass: " + pass.toString());
    }
}

This just adds the password into the string and... yeah, it works well. Check it out... It is very simple; I wrote it.

To retrieve data from database:

 private void CreateConnection()
 {
    string ConnStr =
    ConfigurationManager.ConnectionStrings["ConnStr"].ConnectionString;
    Conn = new SqlConnection(ConnStr);
 }
 public DataTable getData()
 {
 CreateConnection();
    string SqlString = "SELECT * FROM TableName WHERE SomeID = @SomeID;";
    SqlDataAdapter sda = new SqlDataAdapter(SqlString, Conn);
    DataTable dt = new DataTable();
    try
    {
        Conn.Open();
        sda.Fill(dt);
    }
    catch (SqlException se)
    {
        DBErLog.DbServLog(se, se.ToString());
    }
    finally
    {
        Conn.Close();
    }
    return dt;
}

You can't create an array without a size. You'd need to use a list for that.

I use Console.WriteLine() for use in the Output window...

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

Use an inner join instead:

SELECT ...
FROM SomeTable
JOIN
(SELECT 'bla%' AS Pattern 
UNION ALL SELECT '%foo%'
UNION ALL SELECT 'batz%'
UNION ALL SELECT 'abc'
) AS Patterns
ON SomeTable.SomeColumn LIKE Patterns.Pattern

PEP 3155 introduced __qualname__, which was implemented in Python 3.3.

For top-level functions and classes, the __qualname__ attribute is equal to the __name__ attribute. For nested classes, methods, and nested functions, the __qualname__ attribute contains a dotted path leading to the object from the module top-level.

It is accessible from within the very definition of a class or a function, so for instance:

class Foo:
    print(__qualname__)

will effectively print Foo. You'll get the fully qualified name (excluding the module's name), so you might want to split it on the . character.

However, there is no way to get an actual handle on the class being defined.

>>> class Foo:
...     print('Foo' in globals())
... 
False

As other answers mention, as for python 3.7+, the dict is ordered by definition. Instead of subclassing OrderedDict we can subclass abc.collections.MutableSet or typing.MutableSet using the dict's keys to store our values.

class OrderedSet(typing.MutableSet[T]):
    """A set that preserves insertion order by internally using a dict."""

    def __init__(self, iterable: t.Iterator[T]):
        self._d = dict.fromkeys(iterable)

    def add(self, x: T) -> None:
        self._d[x] = None

    def discard(self, x: T) -> None:
        self._d.pop(x)

    def __contains__(self, x: object) -> bool:
        return self._d.__contains__(x)

    def __len__(self) -> int:
        return self._d.__len__()

    def __iter__(self) -> t.Iterator[T]:
        return self._d.__iter__()

Then just:

x = OrderedSet([1, 2, -1, "bar"])
x.add(0)
assert list(x) == [1, 2, -1, "bar", 0]

I put this code in a small library, so anyone can just pip install it.

Generally a parameter is what appears in the definition of the method. An argument is the instance passed to the method during runtime.

You can see a description here: http://en.wikipedia.org/wiki/Parameter_(computer_programming)#Parameters_and_arguments

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...
fi

If you run Linux and have the extension you could simply read the MIME type from /etc/mime.types by making a hash array. You can then store that in memory and simply call the MIME by array key :)

/**
 * Helper function to extract all mime types from the default Linux /etc/mime.types
 */
function get_mime_types() {
    $mime_types = array();
    if (
        file_exists('/etc/mime.types') &&
        ($fh = fopen('/etc/mime.types', 'r')) !== false
    ) {
        while (($line = fgets($fh)) !== false) {
            if (!trim($line) || substr($line, 0, 1) === '#') continue;
            $mime_type = preg_split('/\t+/', rtrim($line));
            if (
                is_array($mime_type) &&
                isset($mime_type[0]) && $mime_type[0] &&
                isset($mime_type[1]) && $mime_type[1]
            ) {
                foreach (explode(' ', $mime_type[1]) as $ext) {
                    $mime_types[$ext] = $mime_type[0];
                }
            }
        }
        fclose($fh);
    }
    return $mime_types;
}

Edit: CMake now has builtin support for this. See new answer.

You can also force the build of the dependent target in a secondary make process

See my answer on a related topic.

You can't modify a String in Java. They are immutable. All you can do is create a new string that is substring of the old string, minus the last character.

In some cases a StringBuffer might help you instead.

I faced this problem a couple of times. The following solution worked for me.

1. copy the existing pom file as a back up, and delete the dependency that's causing this error. delete the contents of the folder which this artifact is referring to.
2. add the deleted dependency in the pom again and add the jar files in that folder.
3. do a Maven->update Project. The errors will go away.

As a side note, sometimes when you're copying files from some other computer there may be encryption.

Open the layout file "_Layout.cshtml" or your custom one

At the part of the code you see, as below:

@Scripts.Render("~/bundles/bootstrap")
@RenderSection("scripts", required: false)
@Scripts.Render("~/bundles/jquery")

Remove the line "@Scripts.Render("~/bundles/jquery")"

(at the part of the code you see) past as the latest line, as below:

@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")
@Scripts.Render("~/bundles/jquery")

This help me and hope helps you as well.

i know this question is old, but hopefully it will help someone. i found a great plugin for those who are using PyCharm IDE: string-manipulation that can easily escape double quotes (and many more...), this plugin is great for cases where you know what the string going to be. for other cases, using json.dumps(string) will be the recommended solution

str_to_escape = 'my string with "double quotes" blablabla'

after_escape = 'my string with \"double quotes\" blablabla'

If you want to set through xml using android's default color codes, then you need to do as below:

android:background="@android:color/white"

If you have colors specified in your project's colors.xml, then use:

android:background="@color/white"

If you want to do programmatically, then do:

linearlayout.setBackgroundColor(Color.WHITE);

Not totally related, but you can also check for both undefined AND empty (for e.g my_variable:) variable. (NOTE: only works with ansible version > 1.9, see: link)

- name: Create user
  user:
    name: "{{ ((my_variable == None) | ternary('default_value', my_variable)) \
    if my_variable is defined else 'default_value' }}"

You can use the DBMS_ALERT package as follows:

CREATE OR REPLACE FUNCTION sleep(seconds IN NUMBER) RETURN NUMBER
AS
    PRAGMA AUTONOMOUS_TRANSACTION;
    message VARCHAR2(200);
    status  INTEGER;
BEGIN
    DBMS_ALERT.WAITONE('noname', message, status, seconds);
    ROLLBACK;
    RETURN seconds;
END;

SELECT sleep(3) FROM dual;

I got the same issue and after a lot of time spent on the search I found the solution

Properties -> FormBorderStyle -> FixedSingle

There is no other real query, this is how prepared statements work. The values are bound in the database server, not in the application layer.

See my answer to this question: In PHP with PDO, how to check the final SQL parametrized query?

(Repeated here for convenience:)

Using prepared statements with parametrised values is not simply another way to dynamically create a string of SQL. You create a prepared statement at the database, and then send the parameter values alone.

So what is probably sent to the database will be a PREPARE ..., then SET ... and finally EXECUTE ....

You won't be able to get some SQL string like SELECT * FROM ..., even if it would produce equivalent results, because no such query was ever actually sent to the database.

Here is a possible frustrating scenarios that produces this error:

If you are lunching a new instance from an AMI you created of another instance (say instance xyz), then the new instance will only accept the same key that instance A used. This is totally understandable but it gets confusing because during the step by step process of creating the new instance, you are asked to select or create a key (at the very last step) which will not work.

Regardless of the key you create or select, only the key you were using for instance XYZ will will be accepted by the new instance.

This may become more of an issue as the next generation of browsers come out with some flavor of a JavaScript compiler. Code executed via Eval may not perform as well as the rest of your JavaScript against these newer browsers. Someone should do some profiling.

I had the same error I fixed it doing this if you are waiting for data like me using retrofit or something like that

Put before Oncreate

private ArtistArrayAdapter adapter;
private RecyclerView recyclerView;

Put them in your Oncreate

 recyclerView = (RecyclerView) findViewById(R.id.cardList);
 recyclerView.setHasFixedSize(true);
 recyclerView.setLayoutManager(new LinearLayoutManager(this));
 adapter = new ArtistArrayAdapter( artists , R.layout.list_item ,getApplicationContext());
 recyclerView.setAdapter(adapter);

When you receive data put

adapter = new ArtistArrayAdapter( artists , R.layout.list_item ,getApplicationContext());
recyclerView.setAdapter(adapter);

Now go in your ArtistArrayAdapter class and do this what it will do is if your array is empty or is null it will make GetItemCount return 0 if not it will make it the size of artists array

@Override
public int getItemCount() {

    int a ;

    if(artists != null && !artists.isEmpty()) {

        a = artists.size();
    }
    else {

        a = 0;

     }

   return a;
}

This eclipse documentation has details on the markups in .project file: The project description file

It describes the .project file as:

When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"

I had the same problem, here is my description of the problem

"I created a store procedure which would generate 2200 Rows and would get executed in almost 2 seconds however after calling the store procedure from SSRS 2008 and run the report it actually never ran and ultimately I have to kill the BIDS (Business Intelligence development Studio) from task manager".

What I Tried: I tried running the SP from reportuser Login but SP was running normal for that user as well, I checked Profiler but nothing worked out.

Solution:

Actually the problem is that even though SP is generating the result but SSRS engine is taking time to read these many rows and render it back. So I added WITH RECOMPILE option in SP and ran the report .. this is when miracle happened and my problem got resolve.

I had made the /var/www to be a soft link to the required directory (for example, /users/username/projects) and things were fine after that.

However, naturally, the original /var/www needs to be deleted - or renamed.

info frame to show the stack frame info

To read the memory at given addresses you should take a look at x

x/x $esp for hex x/d $esp for signed x/u $esp for unsigned etc. x uses the format syntax, you could also take a look at the current instruction via x/i $eip etc.

To attempt command line arguments directly is not possible.

One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).

This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html

so sudo systemctl restart myprog -v -- systemctl will think you're trying to set one of its flags, not myprog's flag.

sudo systemctl restart myprog someotheroption -- systemctl will restart myprog and the someotheroption service, if it exists.

Downside of all answers here is that they use static field names, so I wrote an adjusted version in OOP style. Assumed you are using getter methods you could directly use this Class and use the field name as parameter. Probably someone find it useful.

class CustomSort{

    public $field = '';

    public function cmp($a, $b)
    {
        /**
         * field for order is in a class variable $field
         * using getter function with naming convention getVariable() we set first letter to uppercase
         * we use variable variable names - $a->{'varName'} would directly access a field
         */
        return strcmp($a->{'get'.ucfirst($this->field)}(), $b->{'get'.ucfirst($this->field)}());
    }

    public function sortObjectArrayByField($array, $field)
    {
        $this->field = $field;
        usort($array, array("Your\Namespace\CustomSort", "cmp"));;
        return $array;
    }
} 

Should be AND instead of OR

Dedicated to all those who say it is impossible.

This program collects all information available to reconstruct the original commandline. Then, it launches it and since it is the very same command, your application starts a second time. Then we exit the original program, the child program remains running (even under Linux) and does the very same thing.

WARNING: If you run this, be aware that it never ends creating new processes, similar to a fork bomb.

In later Elasticsearch versions (7.x), types were removed. Updating a mapping can becomes:

curl -XPUT "http://localhost:9200/test/_mapping" -H 'Content-Type: application/json' -d'{
  "properties": {
    "new_geo_field": {
      "type": "geo_point"
    }
  }
}'

As others have pointed out, if the field exists, you typically have to reindex. There are exceptions, such as adding a new sub-field or changing analysis settings.

You can't "create a mapping", as the mapping is created with the index. Typically, you'd define the mapping when creating the index (or via index templates):

curl -XPUT "http://localhost:9200/test" -H 'Content-Type: application/json' -d'{
  "mappings": {
    "properties": {
      "foo_field": {
        "type": "text"
      }
    }
  }
}'

That's because, in production at least, you'd want to avoid letting Elasticsearch "guess" new fields. Which is what generated this question: geo data was read as an array of long values.

Imagine that we have 3 buttons for example

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked 
            // Yes we will handle click here but which button clicked??? We don't know

        }
    };

}

So what we will do?

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(mCorkyListener);
        button2.setOnClickListener(mCorkyListener);
        button3.setOnClickListener(mCorkyListener);

    }

    // Create an anonymous implementation of OnClickListener
    private View.OnClickListener mCorkyListener = new View.OnClickListener() {
        public void onClick(View v) {
            // do something when the button is clicked
            // Yes we will handle click here but which button clicked??? We don't know

            // So we will make
            switch (v.getId() /*to get clicked view id**/) {
                case R.id.corky:

                    // do something when the corky is clicked

                    break;
                case R.id.corky2:

                    // do something when the corky2 is clicked

                    break;
                case R.id.corky3:

                    // do something when the corky3 is clicked

                    break;
                default:
                    break;
            }
        }
    };

}

Or we can do this:

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky is clicked
            }
        });
        button2.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky2 is clicked
            }
        });
        button3.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // do something when the corky3 is clicked
            }
        });

    }

}

Or we can implement View.OnClickListener and i think it's the best way:

public class MainActivity extends ActionBarActivity implements View.OnClickListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);


        // Capture our button from layout
        Button button = (Button)findViewById(R.id.corky);
        Button button2 = (Button)findViewById(R.id.corky2);
        Button button3 = (Button)findViewById(R.id.corky3);
        // Register the onClick listener with the implementation above
        button.setOnClickListener(this);
        button2.setOnClickListener(this);
        button3.setOnClickListener(this);

    }

    @Override
    public void onClick(View v) {
        // do something when the button is clicked
        // Yes we will handle click here but which button clicked??? We don't know

        // So we will make
        switch (v.getId() /*to get clicked view id**/) {
            case R.id.corky:

                // do something when the corky is clicked

                break;
            case R.id.corky2:

                // do something when the corky2 is clicked

                break;
            case R.id.corky3:

                // do something when the corky3 is clicked

                break;
            default:
                break;
        }
    }
}

Finally there is no real differences here Just "Way better than the other"

I've experienced problems with large sqlite files when using the vacuum command.

I haven't tried the auto_vacuum feature yet. If you expect to be updating and deleting data often then this is worth looking at.

Swift 3

you can use index(where:) in Swift 3

func index(where predicate: @noescape Element throws -> Bool) rethrows -> Int?

example

if let i = theArray.index(where: {$0.name == "Foo"}) {
    return theArray[i]
}

You can just specify the generic octet-stream MIME type:

public FileResult Download()
{
    byte[] fileBytes = System.IO.File.ReadAllBytes(@"c:\folder\myfile.ext");
    string fileName = "myfile.ext";
    return File(fileBytes, System.Net.Mime.MediaTypeNames.Application.Octet, fileName);
}

Leaving this here just in case anyone needs...

I needed to have custom domains for a Wordpress Multisite setup in IIS Express but nothing worked until I ran Webmatrix/Visual Studio as an Administrator. Then I was able to bind subdomains to the same application.

<bindings> 
    <binding protocol="http" bindingInformation="*:12345:localhost" />
    <binding protocol="http" bindingInformation="*:12345:whatever.localhost" />
</bindings>

Then going to http://whatever.localhost:12345/ will run.

You can use .present? which comes included with ActiveSupport.

@city = @user.city.present?
# etc ...

You could even write it like this

def show
  %w(city state bio contact twitter mail).each do |attr|
    instance_variable_set "@#{attr}", @user[attr].present?
  end
end

It's worth noting that if you want to test if something is blank, you can use .blank? (this is the opposite of .present?)

Also, don't use foo == nil. Use foo.nil? instead.

The top answer is actually wrong.

The suggested equation: a - (b * (a \ b))

Will solve to: a - a

Which is of course 0 in all cases.

The correct equation is:

a - (b * INT(a \ b))

Or, if the number (a) can be negative, use this:

a - (b * FIX(a \ b))

The following code is less complex and gives the same result. Note that 'X' is the number of seconds to be converted to hours.

In Oracle use:

SELECT TO_CHAR (TRUNC (SYSDATE) + NUMTODSINTERVAL (X, 'second'),
                'hh24:mi:ss'
               ) hr
  FROM DUAL;

In SqlServer use:

SELECT CONVERT(varchar, DATEADD(s, X, 0), 108);

Had the same problem in Eclipse. For some reason I didn't have the servlet.jar file in my build path. What I wound up doing was copying a "lib" folder from another project of mine to the project I was working on, then manually going into that folder and adding the servlet.jar file to the build path (option shows up when you right-click on the file in the project explorer).

The way you're doing it you're querying for the process twice. Also Lynn raises a good point about being nice first. I'd probably try something like the following:

# get Firefox process
$firefox = Get-Process firefox -ErrorAction SilentlyContinue
if ($firefox) {
  # try gracefully first
  $firefox.CloseMainWindow()
  # kill after five seconds
  Sleep 5
  if (!$firefox.HasExited) {
    $firefox | Stop-Process -Force
  }
}
Remove-Variable firefox

I suppose, you mean converting a list into a numpy array? Then,

import numpy as np

# b is some list, then ...    
a = np.array(b).reshape(lengthDim0, lengthDim1);

gives you a as an array of list b in the shape given in reshape.

Here are two approaches:

If your country or working environment blocks sites like Github.

Then you can build a proxy, e.g. use xxnet, which is free & based on Google's GAE, and available for Windows / Linux / Mac.

Then set proxy address for git, e.g:

git config --global http.proxy 127.0.0.1:8087

.class targets the following element:

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

#class targets the following element:

<div id="class"></div>

Note that the id MUST be unique throughout the document, whilst any number of elements may share a class.

You most likely want to examine the documentation for T-SQL's CAST and CONVERT functions, located in the documentation here: http://msdn.microsoft.com/en-US/library/ms187928(v=SQL.90).aspx

You will then use one of those functions in your T-SQL query to convert the [idate] column from the database into the datetime format of your liking in the output.

use the following code,

    iv.setImageResource(getResources().getIdentifier("apple", "drawable", getPackageName()));

What you are looking for is 'type casting'. typecasting (putting the type you know you want in brackets) tells the compiler you know what you are doing and are cool with it. The old way that is inherited from C is as follows.

float var_a = 9.99;
int   var_b = (int)var_a;

If you had only tried to write

int var_b = var_a;

You would have got a warning that you can't implicitly (automatically) convert a float to an int, as you lose the decimal.

This is referred to as the old way as C++ offers a superior alternative, 'static cast'; this provides a much safer way of converting from one type to another. The equivalent method would be (and the way you should do it)

float var_x = 9.99;
int   var_y = static_cast<int>(var_x);

This method may look a bit more long winded, but it provides much better handling for situations such as accidentally requesting a 'static cast' on a type that cannot be converted. For more information on the why you should be using static cast, see this question.

I was solving this leetcode problem and I came across this beautiful solution by a user named Zitao Wang.

The problem goes like this for each element in the given array find the product of all the remaining numbers without making use of divison and in O(n) time

The standard solution is:

Pass 1: For all elements compute product of all the elements to the left of it
Pass 2: For all elements compute product of all the elements to the right of it
        and then multiplying them for the final answer 

His solution uses only one for loop by making use of. He computes the left product and right product on the fly using ~

def productExceptSelf(self, nums):
    res = [1]*len(nums)
    lprod = 1
    rprod = 1
    for i in range(len(nums)):
        res[i] *= lprod
        lprod *= nums[i]
        res[~i] *= rprod
        rprod *= nums[~i]
    return res

That's because there are no spaces in that long string so it has to break out of its container. Add word-break:break-all; to your .title rules to force a break.

#calendar_container > #events_container > .event_block > .title {
    width:400px;
    font-size:12px;
    word-break:break-all;
}

jsFiddle example

Your problem may be solved if you give your div a fixed width, as follows:

div#thing {
    position: absolute;
    top: 0px;
    z-index: 2;
    width:400px;
    margin-left:-200px;
    left:50%;
}

Bigtable

A Distributed Storage System for Structured Data

Bigtable is a distributed storage system (built by Google) for managing structured data that is designed to scale to a very large size: petabytes of data across thousands of commodity servers.

Many projects at Google store data in Bigtable, including web indexing, Google Earth, and Google Finance. These applications place very different demands on Bigtable, both in terms of data size (from URLs to web pages to satellite imagery) and latency requirements (from backend bulk processing to real-time data serving).

Despite these varied demands, Bigtable has successfully provided a flexible, high-performance solution for all of these Google products.

Some features

• fast and extremely large-scale DBMS
• a sparse, distributed multi-dimensional sorted map, sharing characteristics of both row-oriented and column-oriented databases.
• designed to scale into the petabyte range
• it works across hundreds or thousands of machines
• it is easy to add more machines to the system and automatically start taking advantage of those resources without any reconfiguration
• each table has multiple dimensions (one of which is a field for time, allowing versioning)
• tables are optimized for GFS (Google File System) by being split into multiple tablets - segments of the table as split along a row chosen such that the tablet will be ~200 megabytes in size.

Architecture

BigTable is not a relational database. It does not support joins nor does it support rich SQL-like queries. Each table is a multidimensional sparse map. Tables consist of rows and columns, and each cell has a time stamp. There can be multiple versions of a cell with different time stamps. The time stamp allows for operations such as "select 'n' versions of this Web page" or "delete cells that are older than a specific date/time."

In order to manage the huge tables, Bigtable splits tables at row boundaries and saves them as tablets. A tablet is around 200 MB, and each machine saves about 100 tablets. This setup allows tablets from a single table to be spread among many servers. It also allows for fine-grained load balancing. If one table is receiving many queries, it can shed other tablets or move the busy table to another machine that is not so busy. Also, if a machine goes down, a tablet may be spread across many other servers so that the performance impact on any given machine is minimal.

Tables are stored as immutable SSTables and a tail of logs (one log per machine). When a machine runs out of system memory, it compresses some tablets using Google proprietary compression techniques (BMDiff and Zippy). Minor compactions involve only a few tablets, while major compactions involve the whole table system and recover hard-disk space.

The locations of Bigtable tablets are stored in cells. The lookup of any particular tablet is handled by a three-tiered system. The clients get a point to a META0 table, of which there is only one. The META0 table keeps track of many META1 tablets that contain the locations of the tablets being looked up. Both META0 and META1 make heavy use of pre-fetching and caching to minimize bottlenecks in the system.

Implementation

BigTable is built on Google File System (GFS), which is used as a backing store for log and data files. GFS provides reliable storage for SSTables, a Google-proprietary file format used to persist table data.

Another service that BigTable makes heavy use of is Chubby, a highly-available, reliable distributed lock service. Chubby allows clients to take a lock, possibly associating it with some metadata, which it can renew by sending keep alive messages back to Chubby. The locks are stored in a filesystem-like hierarchical naming structure.

There are three primary server types of interest in the Bigtable system:

1. Master servers: assign tablets to tablet servers, keeps track of where tablets are located and redistributes tasks as needed.
2. Tablet servers: handle read/write requests for tablets and split tablets when they exceed size limits (usually 100MB - 200MB). If a tablet server fails, then a 100 tablet servers each pickup 1 new tablet and the system recovers.
3. Lock servers: instances of the Chubby distributed lock service. Lots of actions within BigTable require acquisition of locks including opening tablets for writing, ensuring that there is no more than one active Master at a time, and access control checking.

Example from Google's research paper:

A slice of an example table that stores Web pages. The row name is a reversed URL. The contents column family contains the page contents, and the anchor column family contains the text of any anchors that reference the page. CNN's home page is referenced by both the Sports Illustrated and the MY-look home pages, so the row contains columns named anchor:cnnsi.com and anchor:my.look.ca. Each anchor cell has one version; the contents column has three versions, at timestamps t3, t5, and t6.

API

Typical operations to BigTable are creation and deletion of tables and column families, writing data and deleting columns from a row. BigTable provides this functions to application developers in an API. Transactions are supported at the row level, but not across several row keys.

Here is the link to the PDF of the research paper.

And here you can find a video showing Google's Jeff Dean in a lecture at the University of Washington, discussing the Bigtable content storage system used in Google's backend.

I got this error as sa. In my case, database security didn't matter. I added everyone full control to the mdf and ldf files, and attach went fine.

Use this if you're using fragment or add it in your button click listener. This works for me.

requireActivity().onBackPressed()

Called when the activity has detected the user's press of the back key. The getOnBackPressedDispatcher() OnBackPressedDispatcher} will be given chance to handle the back button before the default behavior of android.app.Activity#onBackPressed()} is invoked.

I was calling parentView.removeView(childView) and childView was still showing. I eventually realized that a method was somehow being triggered twice and added the childView to the parentView twice.

So, use parentView.getChildCount() to determine how many children the parent has before you add a view and afterwards. If the child is added too many times then the top most child is being removed and the copy childView remains-which looks like removeView is working even when it is.

Also, you shouldn't use View.GONE to remove a view. If it's truly removed then you won't need to hide it, otherwise it's still there and you're just hiding it from yourself :(

win = new BrowserWindow({width: 1000, height: 1000,icon: __dirname + '/logo.png'}); //*.png or *.ico will also work 

in my case it worked !

After half a day of fiddling with this, found out that PDO had a bug where...

--

//This would run as expected:
$pdo->exec("valid-stmt1; valid-stmt2;");

--

//This would error out, as expected:
$pdo->exec("non-sense; valid-stmt1;");

--

//Here is the bug:
$pdo->exec("valid-stmt1; non-sense; valid-stmt3;");

It would execute the "valid-stmt1;", stop on "non-sense;" and never throw an error. Will not run the "valid-stmt3;", return true and lie that everything ran good.

I would expect it to error out on the "non-sense;" but it doesn't.

Here is where I found this info: Invalid PDO query does not return an error

Here is the bug: https://bugs.php.net/bug.php?id=61613

So, I tried doing this with mysqli and haven't really found any solid answer on how it works so I thought I's just leave it here for those who want to use it..

try{
    // db connection
    $mysqli = new mysqli("host", "user" , "password", "database");
    if($mysqli->connect_errno){
        throw new Exception("Connection Failed: [".$mysqli->connect_errno. "] : ".$mysqli->connect_error );
        exit();
    }

    // read file.
    // This file has multiple sql statements.
    $file_sql = file_get_contents("filename.sql");

    if($file_sql == "null" || empty($file_sql) || strlen($file_sql) <= 0){
        throw new Exception("File is empty. I wont run it..");
    }

    //run the sql file contents through the mysqli's multi_query function.
    // here is where it gets complicated...
    // if the first query has errors, here is where you get it.
    $sqlFileResult = $mysqli->multi_query($file_sql);
    // this returns false only if there are errros on first sql statement, it doesn't care about the rest of the sql statements.

    $sqlCount = 1;
    if( $sqlFileResult == false ){
        throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], [".$mysqli->errno."]: '".$mysqli->error."' }");
    }

    // so handle the errors on the subsequent statements like this.
    // while I have more results. This will start from the second sql statement. The first statement errors are thrown above on the $mysqli->multi_query("SQL"); line
    while($mysqli->more_results()){
        $sqlCount++;
        // load the next result set into mysqli's active buffer. if this fails the $mysqli->error, $mysqli->errno will have appropriate error info.
        if($mysqli->next_result() == false){
            throw new Exception("File: '".$fullpath."' , Query#[".$sqlCount."], Error No: [".$mysqli->errno."]: '".$mysqli->error."' }");
        }
    }
}
catch(Exception $e){
    echo $e->getMessage(). " <pre>".$e->getTraceAsString()."</pre>";
}

Or, if you are looking for simple collection of errors for your apps.. here is my implementation of this:

public override void OnActionExecuting(HttpActionContext actionContext)
    {
        var modelState = actionContext.ModelState;

        if (!modelState.IsValid) 
        {

            var errors = new List<string>();
            foreach (var state in modelState)
            {
                foreach (var error in state.Value.Errors)
                {
                    errors.Add(error.ErrorMessage);
                }
            }

            var response = new { errors = errors };

            actionContext.Response = actionContext.Request
                .CreateResponse(HttpStatusCode.BadRequest, response, JsonMediaTypeFormatter.DefaultMediaType);
        }
    }

Error Message Response will look like:

{
  "errors": [
    "Please enter a valid phone number (7+ more digits)",
    "Please enter a valid e-mail address"
  ]
}

Synchronized method

Synchronized methods have two effects.
First, when one thread is executing a synchronized method for an object, all other threads that invoke synchronized methods for the same object block (suspend execution) until the first thread is done with the object.

Second, when a synchronized method exits, it automatically establishes a happens-before relationship with any subsequent invocation of a synchronized method for the same object. This guarantees that changes to the state of the object are visible to all threads.

Note that constructors cannot be synchronized — using the synchronized keyword with a constructor is a syntax error. Synchronizing constructors doesn't make sense, because only the thread that creates an object should have access to it while it is being constructed.

Synchronized Statement

Unlike synchronized methods, synchronized statements must specify the object that provides the intrinsic lock: Most often I use this to synchronize access to a list or map but I don't want to block access to all methods of the object.

Q: Intrinsic Locks and Synchronization Synchronization is built around an internal entity known as the intrinsic lock or monitor lock. (The API specification often refers to this entity simply as a "monitor.") Intrinsic locks play a role in both aspects of synchronization: enforcing exclusive access to an object's state and establishing happens-before relationships that are essential to visibility.

Every object has an intrinsic lock associated with it. By convention, a thread that needs exclusive and consistent access to an object's fields has to acquire the object's intrinsic lock before accessing them, and then release the intrinsic lock when it's done with them. A thread is said to own the intrinsic lock between the time it has acquired the lock and released the lock. As long as a thread owns an intrinsic lock, no other thread can acquire the same lock. The other thread will block when it attempts to acquire the lock.

package test;

public class SynchTest implements Runnable {  
    private int c = 0;

    public static void main(String[] args) {
        new SynchTest().test();
    }

    public void test() {
        // Create the object with the run() method
        Runnable runnable = new SynchTest();
        Runnable runnable2 = new SynchTest();
        // Create the thread supplying it with the runnable object
        Thread thread = new Thread(runnable,"thread-1");
        Thread thread2 = new Thread(runnable,"thread-2");
//      Here the key point is passing same object, if you pass runnable2 for thread2,
//      then its not applicable for synchronization test and that wont give expected
//      output Synchronization method means "it is not possible for two invocations
//      of synchronized methods on the same object to interleave"

        // Start the thread
        thread.start();
        thread2.start();
    }

    public synchronized  void increment() {
        System.out.println("Begin thread " + Thread.currentThread().getName());
        System.out.println(this.hashCode() + "Value of C = " + c);
//      If we uncomment this for synchronized block, then the result would be different
//      synchronized(this) {
            for (int i = 0; i < 9999999; i++) {
                c += i;
            }
//      }
        System.out.println("End thread " + Thread.currentThread().getName());
    }

//    public synchronized void decrement() {
//        System.out.println("Decrement " + Thread.currentThread().getName());
//    }

    public int value() {
        return c;
    }

    @Override
    public void run() {
        this.increment();
    }
}

Cross check different outputs with synchronized method, block and without synchronization.

In one of my machine, delimiting the word with "\b" (without the quotes) did not work. The solution was to use "\<" for starting delimiter and "\>" for ending delimiter.

To explain with Joakim Lundberg's example:

$ echo "bar embarassment" | sed "s/\<bar\>/no bar/g"
no bar embarassment

Well I am not sure what actual cause is but I have done this way for the same error. I have comment out this annotation for the servelet and its working.

//@WebServlet("/HelloWorld")
public class HelloWorld extends HttpServlet {

Dont know that could be proper solution of not. but this worked and another thing that can be test is add servlet jar into class path. That might work.

I was able to add an app icon to my react-native android project by following this guy's advice and using Android Asset Studio

Here it is, transcribed in case the link goes dead:

How to upload an Application Icon in React-Native Android

1) Upload your image to Android Asset Studio. Pick whatever effects you’d like to apply. The tool generates a zip file for you. Click Download .Zip.

2) Unzip the file on your machine. Then drag over the images you want to your /android/app/src/main/res/ folder. Make sure to put each image in the right subfolder mipmap-{hdpi, mdpi, xhdpi, xxhdpi, xxxhdpi}.

3) Do not (as I originally did) naively drag and drop the whole folder over your res folder. As you may be removing your /res/values/{strings,styles}.xml files altogether.

I use vim 7.4 and this works for me.
Assuming we are commenting/uncommenting 3 lines.

To comment:

if the line has no tab/space at the beginning:
ctrl + V then jjj then shift + I (cappital i) then //then esc esc
if the line has tab/space at the beginning you still can do the above or swap for c:
ctrl + V then jjj then c then //then esc esc

To uncomment:

if the lines have no tab/space at the beginning:
ctrl + V then jjj then ll (lower cap L) then c

if the lines have tab/space at the beginning, then you space one over and esc
ctrl + V then jjj then ll (lower cap L) then c then space then esc

Some good answers here. Especially the one by @torek. I thought I'd add this work-around with a little explanation for those in a rush.

To summarize, what happens is that when you move a tag locally, it changes the tag from a non-Null commit value to a different value. However, because git (as a default behavior) doesn't allow changing non-Null remote tags, you can't push the change.

The work-around is to delete the tag (and tick remove all remotes). Then create the same tag and push.

In Python pandas provide head() and tail() to print head and tail data respectively.

import pandas as pd
train = pd.read_csv('file_name')
train.head() # it will print 5 head row data as default value is 5
train.head(n) # it will print n head row data
train.tail() #it will print 5 tail row data as default value is 5
train.tail(n) #it will print n tail row data

My 2 cents:

    using (ZipArchive archive = ZipFile.Open(zFile, ZipArchiveMode.Create))
    {
        foreach (var fPath in filePaths)
        {
            archive.CreateEntryFromFile(fPath,Path.GetFileName(fPath));
        }
    }

So Zip files could be created directly from files/dirs.

I have just found a PHP function "strip_tags()" and its working in my case.

I tried to convert the following HTML :

<p><span style="font-family: 'Verdana','sans-serif'; color: black; font-size: 7.5pt;">&nbsp;</span>Many  practitioners are optimistic that the eyeglass and contact lens  industry will recover from the recent economic storm. Did your practice  feel its affects?&nbsp; Statistics show revenue notably declined in 2008 and  2009.

After applying strip_tags() function, I have got the following output :

 Many  practitioners are optimistic that the eyeglass and contact lens  industry will recover from the recent economic storm. Did your practice  feel its affects?  Statistics show revenue notably declined in 2008 and  2009.

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

Sub stituterangersNEW()
Dim t As Range
Dim x As Range
Dim dify As Boolean
Dim difx As Boolean

Dim time1 As Date

    'You said time1 doesn't change, so I left it in a singe cell.
    'If that is not correct, you will have to play with this some more.
    time1 = Range("A6").Value

    'Looping through each of our output cells.
    For Each t In Range("B7:E9") 'Change these to match your real ranges.

        'Looping through each departure date/time.

            'then we'll move to the next dep time (x)
        Next x
    Next t

End Sub

EDIT

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

     A                      B                   C                   D                  E

Using the sub I got this output:

Character varying is different than text. Try running

ALTER TABLE product_product ALTER COLUMN code TYPE text;

That will change the column type to text, which is limited to some very large amount of data (you would probably never actually hit it.)

Sometimes using only the line below throws me an Exception,

String text = listView1.SelectedItems[0].Text; 

so I use this code below:

private void listView1_SelectedIndexChanged(object sender, EventArgs e) 
{ 
    if (listView1.SelectedIndices.Count <= 0) 
    { 
        return; 
    } 
    int intselectedindex = listView1.SelectedIndices[0]; 
    if (intselectedindex >= 0) 
    {
        String text = listView1.Items[intselectedindex].Text;

        //do something
        //MessageBox.Show(listView1.Items[intselectedindex].Text); 
    } 
}

Your import has a subtle error:

import java.awt.List;

It should be:

import java.util.List;

The problem is that both awt and Java's util package provide a class called List. The former is a display element, the latter is a generic type used with collections. Furthermore, java.util.ArrayList extends java.util.List, not java.awt.List so if it wasn't for the generics, it would have still been a problem.

Edit: (to address further questions given by OP) As an answer to your comment, it seems that there is anther subtle import issue.

import org.omg.DynamicAny.NameValuePair;

should be

import org.apache.http.NameValuePair

nameValuePairs now uses the correct generic type parameter, the generic argument for new UrlEncodedFormEntity, which is List<? extends NameValuePair>, becomes valid, since your NameValuePair is now the same as their NameValuePair. Before, org.omg.DynamicAny.NameValuePair did not extend org.apache.http.NameValuePair and the shortened type name NameValuePair evaluated to org.omg... in your file, but org.apache... in their code.

Task.WaitAll blocks the current thread until everything has completed.

Task.WhenAll returns a task which represents the action of waiting until everything has completed.

That means that from an async method, you can use:

await Task.WhenAll(tasks);

... which means your method will continue when everything's completed, but you won't tie up a thread to just hang around until that time.

I solved it by myself.

UPDATE: this only tested with server side rendering ( universal Javascript ) here is my boilerplate.

With only file-loader you can load images dynamically - the trick is to use ES6 template strings so that Webpack can pick it up:

This will NOT work. :

const myImg = './cute.jpg'
<img src={require(myImg)} />

To fix this, just use template strings instead :

const myImg = './cute.jpg'
<img src={require(`${myImg}`)} />

webpack.config.js :

var HtmlWebpackPlugin =  require('html-webpack-plugin')
var ExtractTextWebpackPlugin = require('extract-text-webpack-plugin')

module.exports = {
  entry : './src/app.js',
  output : {
    path : './dist',
    filename : 'app.bundle.js'
  },
  plugins : [
  new ExtractTextWebpackPlugin('app.bundle.css')],
  module : {
    rules : [{
      test : /\.css$/,
      use : ExtractTextWebpackPlugin.extract({
        fallback : 'style-loader',
        use: 'css-loader'
      })
    },{
      test: /\.js$/,
      exclude: /(node_modules)/,
      loader: 'babel-loader',
      query: {
        presets: ['react','es2015']
      }
    },{
      test : /\.jpg$/,
      exclude: /(node_modules)/,
      loader : 'file-loader'
    }]
  }
}

unsigned char c;

for( int i = 7; i >= 0; i-- ) {
    printf( "%d", ( c >> i ) & 1 ? 1 : 0 );
}

printf("\n");

Explanation:

With every iteration, the most significant bit is being read from the byte by shifting it and binary comparing with 1.

For example, let's assume that input value is 128, what binary translates to 1000 0000. Shifting it by 7 will give 0000 0001, so it concludes that the most significant bit was 1. 0000 0001 & 1 = 1. That's the first bit to print in the console. Next iterations will result in 0 ... 0.

This is how you can nest multiple bool queries in one outer bool query this using Kibana,

• bool indicates we are using boolean
• must is for AND
• should is for OR

GET my_inedx/my_type/_search
{
  "query" : {
     "bool": {             //bool indicates we are using boolean operator
          "must" : [       //must is for **AND**
               {
                 "match" : {
                       "description" : "some text"  
                   }
               },
               {
                  "match" :{
                        "type" : "some Type"
                   }
               },
               {
                  "bool" : {          //here its a nested boolean query
                        "should" : [  //should is for **OR**
                               {
                                 "match" : {
                                     //ur query
                                }
                               },
                               { 
                                  "match" : {} 
                               }     
                             ]
                        }
               }
           ]
      }
  }
}

This is how you can nest a query in ES

There are more types in "bool" like,

1. Filter
2. must_not

You can make use of environment variables and the ConfigurationBuilder class in your Startup constructor like this:

public Startup(IHostingEnvironment env)
{
    var builder = new ConfigurationBuilder()
    .SetBasePath(env.ContentRootPath)
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
    .AddJsonFile($"appsettings.{env.EnvironmentName}.json", optional: true)
    .AddEnvironmentVariables();
    this.configuration = builder.Build();
}

Then you create an appsettings.xxx.json file for every environment you need, with "xxx" being the environment name. Note that you can put all global configuration values in your "normal" appsettings.json file and only put the environment specific stuff into these new files.

Now you only need an environment variable called ASPNETCORE_ENVIRONMENT with some specific environment value ("live", "staging", "production", whatever). You can specify this variable in your project settings for your development environment, and of course you need to set it in your staging and production environments also. The way you do it there depends on what kind of environment this is.

UPDATE: I just realized you want to choose the appsettings.xxx.json based on your current build configuration. This cannot be achieved with my proposed solution and I don't know if there is a way to do this. The "environment variable" way, however, works and might as well be a good alternative to your approach.

It depends why the something is on the same line in the first place.

clear in the case of floats, display: block in the case of inline content naturally flowing, nothing will defeat position: absolute as the previous element will be taken out of the normal flow by it.

You need to consider the case where the user presses enter in the middle of the text, not just at the end. I'd suggest detecting the enter key in the keyup event, as suggested, and use a regular expression to ensure the value is as you require:

<textarea id="t" rows="4" cols="80"></textarea>
<script type="text/javascript">
    function formatTextArea(textArea) {
        textArea.value = textArea.value.replace(/(^|\r\n|\n)([^*]|$)/g, "$1*$2");
    }

    window.onload = function() {
        var textArea = document.getElementById("t");
        textArea.onkeyup = function(evt) {
            evt = evt || window.event;

            if (evt.keyCode == 13) {
                formatTextArea(this);
            }
        };
    };
</script>

Above posts answers questions related to URL Encoding and How it works, but the original questions was "Should I URL-encode POST data?" which isn't answered.

From my recent experience with URL Encoding, I would like to extend the question further. "Should I URL-encode POST data, same as GET HTTP method. Generally, HTML Forms over the Browser if are filled, submitted and/or GET some information, Browsers will do URL Encoding but If an application exposes a web-service and expects Consumers to do URL-Encoding on data, is it Architecturally and Technically correct to do URL Encode with POST HTTP method ?"

You can do that using Python 2.

1. Remove request
2. Make that line: from urllib2 import urlopen

You cannot have request in Python 2, you need to have Python 3 or above.

You need to do it like this,

void Yourfunction(List<DateTime> dates )
{

}

EncodeAndSend is not a static function, which means it can be called on an instance of the class CPMSifDlg. You cannot write this:

 CPMSifDlg::EncodeAndSend(/*...*/);  //wrong - EncodeAndSend is not static

It should rather be called as:

 CPMSifDlg dlg; //create instance, assuming it has default constructor!
 dlg.EncodeAndSend(/*...*/);   //correct 

You need to copy the array before you sort it. One way with es6:

const sorted = [...arr].sort();

the spread-syntax as array literal (copied from mdn):

var arr = [1, 2, 3];
var arr2 = [...arr]; // like arr.slice()

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator

This version always returns the number of seconds difference as a positive number (same result as @freedeveloper's solution):

var seconds = System.Math.Abs((date1 - date2).TotalSeconds);

There is a limit on the number of half-open connections, but afaik not for active connections. Although it appears to depend on the type of Windows 2008 server, at least according to this MSFT employee:

It depends on the edition, Web and Foundation editions have connection limits while Standard, Enterprise, and Datacenter do not.

• t2.micro = ~70 MBit/s (qiita says 63 MBit/s) - t1.micro gets about ~100 Mbit/s
• t2.small = ~125 MBit/s (t2, qiita says 127 MBit/s, cloudharmony says 125 Mbit/s with spikes to 200+ Mbit/s)
• *.medium = t2.medium gets 250-300 MBit/s, m3.medium ~400 MBit/s
• *.large = ~450-600 MBit/s (the most variation, see below)
• *.xlarge = 700-900 MBit/s
• *.2xlarge = ~1 GBit/s +- 10%
• *.4xlarge = ~2 GBit/s +- 10%
• *.8xlarge and marked specialty = 10 Gbit, expect ~8.5 GBit/s, requires enhanced networking & VPC for full throughput

m1 small, medium, and large instances tend to perform higher than expected. c1.medium is another freak, at 800 MBit/s.

I gathered this by combing dozens of sources doing benchmarks (primarily using iPerf & TCP connections). Credit to CloudHarmony & flux7 in particular for many of the benchmarks (note that those two links go to google searches showing the numerous individual benchmarks).

Caveats & Notes:

The large instance size has the most variation reported:

• m1.large is ~800 Mbit/s (!!!)
• t2.large = ~500 MBit/s
• c3.large = ~500-570 Mbit/s (different results from different sources)
• c4.large = ~520 MBit/s (I've confirmed this independently, by the way)
• m3.large is better at ~700 MBit/s
• m4.large is ~445 Mbit/s
• r3.large is ~390 Mbit/s

Burstable (T2) instances appear to exhibit burstable networking performance too:

• The CloudHarmony iperf benchmarks show initial transfers start at 1 GBit/s and then gradually drop to the sustained levels above after a few minutes. PDF links to reports below:

• t2.small (PDF)

• t2.medium (PDF)
• t2.large (PDF)

Note that these are within the same region - if you're transferring across regions, real performance may be much slower. Even for the larger instances, I'm seeing numbers of a few hundred MBit/s.

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

If you use IIS Windows Server add web.config file in root folder and put the below code :

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <rewrite>
            <rules>
                <rule name="Imported Rule 1" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{URL}" pattern="^system.*" ignoreCase="false" />
                    </conditions>
                    <action type="Rewrite" url="/index.php/{R:1}" />
                </rule>
                <rule name="Imported Rule 2" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions logicalGrouping="MatchAll">
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                        <add input="{R:1}" pattern="^(index\.php|images|robots\.txt|css)" ignoreCase="false" negate="true" />
                    </conditions>
                    <action type="Rewrite" url="index.php/{R:1}" />
                </rule>
            </rules>
        </rewrite>
    </system.webServer>
</configuration>

and if you use .htaccess use this one :

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

while True:
    b1=input('Type a number:')
    try:
        a1=int(b1)
    except ValueError:
        print ('"%(a1)s" is not a number. Try again.' %{'a1':b1})       
    else:
        print ('You typed "{}".'.format(a1))
        break

This makes a loop to check whether input is an integer or not, result would look like below:

>>> %Run 1.1.py
Type a number:d
"d" is not a number. Try again.
Type a number:
>>> %Run 1.1.py
Type a number:4
You typed 4.
>>> 

You have to add col-md-12 to your inner-navbar. md is for desktop .you can choose other options from bootstrap's list of options . 12 in col-md-12 is for full width .If you want half-width you can use 6 instead of 12 .for e.g. col-md-6.

Here is the solution to your question

    <div class="container">
       <div class="navbar">
          <div class="navbar-inner col-md-12">
               <!-- nav bar items here -->
          </div>
       </div>
   </div>

The A div can actually be made without :before or :after selector but using linear gradient as your first try. The only difference is that you must specify 4 positions. Dark grey from 0 to 50% and ligth grey from 50% to 100% like this:

background: linear-gradient(to right,  #9c9e9f 0%,#9c9e9f 50%,#f6f6f6 50%,#f6f6f6 100%);

As you know, B div is made from a linear gradient having 2 positions like this:

background: linear-gradient(to right,  #9c9e9f 0%,#f6f6f6 100%);

For the C div, i use the same kind of gradient as div A ike this:

background: linear-gradient(to right,  #9c9e9f 0%,#9c9e9f 50%,#33ccff 50%,#33ccff 100%);

But this time i used the :after selector with a white background like if the second part of your div was smaller. * Please note that I added a better alternative below.

There is also an alternative for the C div without using a white background to hide the a part of the second section. Instead, we make the second part transparent and we use the :after selector to act as a colored background with the desired position and size.

Lazy man can use this lib, Just import inside your project and

ImageView mImageView;
PhotoViewAttacher mAttacher;

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

    // Any implementation of ImageView can be used!
    mImageView = (ImageView) findViewById(R.id.iv_photo);

    // Set the Drawable displayed
    Drawable bitmap = getResources().getDrawable(R.drawable.wallpaper);
    mImageView.setImageDrawable(bitmap);

    // Attach a PhotoViewAttacher, which takes care of all of the zooming functionality.
    mAttacher = new PhotoViewAttacher(mImageView);
}


// If you later call mImageView.setImageDrawable/setImageBitmap/setImageResource/etc then you just need to call
mAttacher.update();

I ran into the same problem and was able to resolve it in very powerful way that allows unlimited sorting possibilities.

I created a View using (saving) 2 sort orders (*explanation on how to do so below).

After that I simply applied the update queries to the View created and it worked great.

Here are the 2 queries I used on the view:

1st Query:

Update  MyView
Set SortID=0

2nd Query:

DECLARE @sortID int
SET     @sortID = 0
UPDATE  MyView
SET     @sortID = sortID = @sortID + 1

*To be able to save the sorting on the View I put TOP into the SELECT statement. This very useful workaround allows the View results to be returned sorted as set when the View was created when the View is opened. In my case it looked like:

(NOTE: Using this workaround will place an big load on the server if using a large table and it is therefore recommended to include as few fields as possible in the view if working with large tables)

SELECT     TOP (600000) 
dbo.Items.ID, dbo.Items.Code, dbo.Items.SortID, dbo.Supplier.Date, 
dbo.Supplier.Code AS Expr1
FROM         dbo.Items INNER JOIN
                      dbo.Supplier ON dbo.Items.SupplierCode = dbo.Supplier.Code
ORDER BY dbo.Supplier.Date, dbo.Items.ID DESC

Running: SQL Server 2005 on a Windows Server 2003

resize() not only allocates memory, it also creates as many instances as the desired size which you pass to resize() as argument. But reserve() only allocates memory, it doesn't create instances. That is,

std::vector<int> v1;
v1.resize(1000); //allocation + instance creation
cout <<(v1.size() == 1000)<< endl;   //prints 1
cout <<(v1.capacity()==1000)<< endl; //prints 1

std::vector<int> v2;
v2.reserve(1000); //only allocation
cout <<(v2.size() == 1000)<< endl;   //prints 0
cout <<(v2.capacity()==1000)<< endl; //prints 1

Output (online demo):

1
1
0
1

So resize() may not be desirable, if you don't want the default-created objects. It will be slow as well. Besides, if you push_back() new elements to it, the size() of the vector will further increase by allocating new memory (which also means moving the existing elements to the newly allocated memory space). If you have used reserve() at the start to ensure there is already enough allocated memory, the size() of the vector will increase when you push_back() to it, but it will not allocate new memory again until it runs out of the space you reserved for it.

I needed to find the position of an element inside a ListView and used this snippet that works kind of like .offset:

const UIManager = require('NativeModules').UIManager;
const handle = React.findNodeHandle(this.refs.myElement);
UIManager.measureLayoutRelativeToParent(
  handle, 
  (e) => {console.error(e)}, 
  (x, y, w, h) => {
    console.log('offset', x, y, w, h);
  });

This assumes I had a ref='myElement' on my component.

Refer to the ASP.NET page lifecycle to help find the right event to override. It really depends what you want to do. But yes, there is an unload event.

    protected override void OnUnload(EventArgs e)
    {
        base.OnUnload(e);

        // your code
    }

But just remember (from the above link): During the unload stage, the page and its controls have been rendered, so you cannot make further changes to the response stream. If you attempt to call a method such as the Response.Write method, the page will throw an exception.

You don't need to change the compliance level here, or rather, you should but that's not the issue.

The code compliance ensures your code is compatible with a given Java version.

For instance, if you have a code compliance targeting Java 6, you can't use Java 7's or 8's new syntax features (e.g. the diamond, the lambdas, etc. etc.).

The actual issue here is that you are trying to compile something in a Java version that seems different from the project dependencies in the classpath.

Instead, you should check the JDK/JRE you're using to build.

In Eclipse, open the project properties and check the selected JRE in the Java build path.

If you're using custom Ant (etc.) scripts, you also want to take a look there, in case the above is not sufficient per se.

Guava has a method Ints.asList() for creating a List<Integer> backed by an int[] array. You can use this with Collections.sort to apply the Comparator to the underlying array.

List<Integer> integersList = Ints.asList(arr);
Collections.sort(integersList, Collections.reverseOrder());

Note that the latter is a live list backed by the actual array, so it should be pretty efficient.

You ask two questions; your title says "Displaying a vector of strings", but you're not actually doing that, you actually build a single string composed of all the strings and output that.

Your question body asks "Why doesn't this work".

It doesn't work because your for loop is constrained by "userString.size()" which is 0, and you test your loop variable for being "userString.size() - 1". The condition of a for() loop is tested before permitting execution of the first iteration.

int n = 1;
for (int i = 1; i < n; ++i) {
    std::cout << i << endl;
}

will print exactly nothing.

So your loop executes exactly no iterations, leaving userString and sentence empty.

Lastly, your code has absolutely zero reason to use a vector. The fact that you used "decltype(userString.size())" instead of "size_t" or "auto", while claiming to be a rookie, suggests you're either reading a book from back to front or you are setting yourself up to fail a class.

So to answer your question at the end of your post: It doesn't work because you didn't step through it with a debugger and inspect the values as it went. While I say it tongue-in-cheek, I'm going to leave it out there.

Your class might implement the Comparable interface to achieve the same functionality. Your class should implement the compareTo() method declared in the interface.

public class MyClass implements Comparable<MyClass>{

    String a;

    public MyClass(String ab){
        a = ab;
    }

    // returns an int not a boolean
    public int compareTo(MyClass someMyClass){ 

        /* The String class implements a compareTo method, returning a 0 
           if the two strings are identical, instead of a boolean.
           Since 'a' is a string, it has the compareTo method which we call
           in MyClass's compareTo method.
        */

        return this.a.compareTo(someMyClass.a);

    }

    public static void main(String[] args){

        MyClass object1 = new MyClass("test");
        MyClass object2 = new MyClass("test");

        if(object1.compareTo(object2) == 0){
            System.out.println("true");
        }
        else{
            System.out.println("false");
        }
    }
}

This problem was caused by the li display attribute being set to block in a parent class. Overriding with list-item solved the problem.

An Euler path is a path that passes through every edge exactly once. If it ends at the initial vertex then it is an Euler cycle.

A Hamiltonian path is a path that passes through every vertex exactly once (NOT every edge). If it ends at the initial vertex then it is a Hamiltonian cycle.

In an Euler path you might pass through a vertex more than once.

In a Hamiltonian path you may not pass through all edges.

Try:

<div style="@(Model.booleanVariable ? "display:block" : "display:none")">Some links</div>

Use the "Display" style attribute with your bool model attribute to define the div's visibility.

$last = count($arr_nav) - 1;

foreach ($arr_nav as $i => $row)
{
    $isFirst = ($i == 0);
    $isLast = ($i == $last);

    echo ... $row['name'] ... $row['url'] ...;
}

Your Make file will have one or two dependency rules depending on whether you compile and link with a single command, or with one command for the compile and one for the link.

Dependency are a tree of rules that look like this (note that the indent must be a TAB):

main_target : source1 source2 etc
    command to build main_target from sources

source1 : dependents for source1
    command to build source1

There must be a blank line after the commands for a target, and there must not be a blank line before the commands. The first target in the makefile is the overall goal, and other targets are built only if the first target depends on them.

So your makefile will look something like this.

a3a.exe : a3driver.obj 
    link /out:a3a.exe a3driver.obj

a3driver.obj : a3driver.cpp
    cc a3driver.cpp

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

For Visual Studio 2017 do the following:

Tools > Options > All Languages, then check or uncheck the checkbox based on your preference. As you can see in below image :

All you have to do is open Anaconda Prompt and type

pip install package-name

It will automatically install to the anaconda environment without having to use

conda install package-name

Since some of the conda packages may lack support overtime it is required to install using pip and this is one way to do it

If you have pip installed in anaconda you can run the following in jupyter notebook or in your python shell that is linked to anaconda

pip.main(['install', 'package-name'])

Check your version of pip with pip.__version__. If it is version 10.x.x or above, then install your python package with this line of code

subprocess.check_call([sys.executable, '-m', 'pip', 'install', '--upgrade', 'package-name'])

In your jupyter notebook, you can install python packages through pip in a cell this way;

!pip install package-name

or you could use your python version associated with anaconda

!python3.6 -m pip install package-name

A single backslash works for me:

ry4an@ry4an-mini:~$ mkdir "My Code"

ry4an@ry4an-mini:~$ vi todir.sh

ry4an@ry4an-mini:~$ . todir.sh 

ry4an@ry4an-mini:My Code$ cat ../todir.sh 
#!/bin/sh
cd ~/My\ Code

Are you sure the problem isn't that your shell script is changing directory in its subshell, but then you're back in the main shell (and original dir) when done? I avoided that by using . to run the script in the current shell, though most folks would just use an alias for this. The spaces could be a red herring.

I'm not sure how stuck you are:

You must have a web server (Windows comes with one called IIS, but it may not be installed)

1. Make sure you actually have IIS installed! Try typing http://localhost/ in your browser and see what happens. If nothing happens it means that you may not have IIS installed. See Installing IIS
2. Set up IIS How to set up your first IIS Web site
3. You may even need to Install the .NET Framework (or your server will only serve static html pages, and not asp.net pages)

Installing your application

Once you have done that, you can more or less just copy your application to c:\wwwroot\inetpub\. Read Installing ASP.NET Applications (IIS 6.0) for more information

Accessing the web site from another machine

In theory, once you have a web server running, and the application installed, you only need the IP address of your web server to access the application.

To find your IP address try: Start -> Run -> type cmd (hit ENTER) -> type ipconfig (hit ENTER)

Once

• you have the IP address AND
• IIS running AND
• the application is installed

you can access your website from another machine in your LAN by just typing in the IP Address of you web server and the correct path to your application.

If you put your application in a directory called NewApp, you will need to type something like http://your_ip_address/NewApp/default.aspx

Turn off your firewall

If you do have a firewall turn it off while you try connecting for the first time, you can sort that out later.

Here is a simple example:

    package main

    import "fmt"

    func plusTwo() (func(v int) (int)) {
        return func(v int) (int) {
            return v+2
        }
    }

    func plusX(x int) (func(v int) (int)) {
       return func(v int) (int) {
           return v+x
       }
    }

    func main() {
        p := plusTwo()
        fmt.Printf("3+2: %d\n", p(3))

        px := plusX(3)
        fmt.Printf("3+3: %d\n", px(3))
    }

Actually, there's something wrong about all the other answers about r+ mode.

test.in file's content:

hello1
ok2
byebye3

And the py script's :

with open("test.in", 'r+')as f:
    f.readline()
    f.write("addition")

Execute it and the test.in's content will be changed to :

hello1
ok2
byebye3
addition

However, when we modify the script to :

with open("test.in", 'r+')as f:
    f.write("addition")

the test.in also do the respond:

additionk2
byebye3

So, the r+ mode will allow us to cover the content from the beginning if we did't do the read operation. And if we do some read operation, f.write()will just append to the file.

By the way, if we f.seek(0,0) before f.write(write_content), the write_content will cover them from the positon(0,0).

MD5 is bad because of collision problems - two different passwords possibly generating the same md-5.

Sha-1 would be plenty secure for this. The reason you store the salted sha-1 version of the password is so that you the swerver do not keep the user's apassword on file, that they may be using with other people's servers. Otherwise, what difference does it make?

If the hacker steals your entire unencrypted database some how, the only thing a hashed salted password does is prevent him from impersonating the user for future signons - the hacker already has the data.

What good does it do the attacker to have the hashed value, if what your user inputs is a plain password?

And even if the hacker with future technology could generate a million sha-1 keys a second for a brute force attack, would your server handle a million logons a second for the hacker to test his keys? That's if you are letting the hacker try to logon with the salted sha-1 instead of a password like a normal logon.

The best bet is to limit bad logon attempts to some reasonable number - 25 for example, and then time the user out for a minute or two. And if the cumulative bady logon attempts hits 250 within 24 hours, shut the account access down and email the owner.

Resurrecting a very old thread yet again, since none of the answers here worked very well for me.

I found a simple way that seems pretty robust and simple. It worked for me. The idea:

• Compile your project as a Windows Application. There might be a parent console when your executable starts, but maybe not. The goal is to re-use the existing console if one exists, or create a new one if not.
• AttachConsole(-1) will look for the console of the parent process. If there is one, it attaches to it and you're finished. (I tried this and it worked properly when calling my application from cmd)
• If AttachConsole returned false, there is no parent console. Create one with AllocConsole.

Example:

static class Program
{
    [DllImport( "kernel32.dll", SetLastError = true )]
    static extern bool AllocConsole();

    [DllImport( "kernel32", SetLastError = true )]
    static extern bool AttachConsole( int dwProcessId );

    static void Main(string[] args)
    {
        bool consoleMode = Boolean.Parse(args[0]);
        if (consoleMode)
        {
           if (!AttachConsole(-1))
              AllocConsole();
           Console.WriteLine("consolemode started");
           // ...
        } 
        else
        {
           Application.EnableVisualStyles();
           Application.SetCompatibleTextRenderingDefault(false);
           Application.Run(new Form1());
        }
    }
}

A word of caution : it seems that if you try writing to the console prior to attaching or allocing a console, this approach doesn't work. My guess is the first time you call Console.Write/WriteLine, if there isn't already a console then Windows automatically creates a hidden console somewhere for you. (So perhaps Anthony's ShowConsoleWindow answer is better after you've already written to the console, and my answer is better if you've not yet written to the console). The important thing to note is that this doesn't work:

static void Main(string[] args)
    {
        Console.WriteLine("Welcome to the program");   //< this ruins everything
        bool consoleMode = Boolean.Parse(args[0]);
        if (consoleMode)
        {
           if (!AttachConsole(-1))
              AllocConsole();
           Console.WriteLine("consolemode started");   //< this doesn't get displayed on the parent console
           // ...
        } 
        else
        {
           Application.EnableVisualStyles();
           Application.SetCompatibleTextRenderingDefault(false);
           Application.Run(new Form1());
        }
    }

You can set the outerdiv's CSS to this

#outerdiv {
    overflow: hidden; /* make sure this doesn't cause unexpected behaviour */
}

You can also do this by adding an element at the end with clear: both. This can be added normally, with JS (not a good solution) or with :after CSS pseudo element (not widely supported in older IEs).

The problem is that containers won't naturally expand to include floated children. Be warned with using the first example, if you have any children elements outside the parent element, they will be hidden. You can also use 'auto' as the property value, but this will invoke scrollbars if any element appears outside.

You can also try floating the parent container, but depending on your design, this may be impossible/difficult.

You maybe wanted to do the following:

foreach($user->data as $mydata)

    {
         echo $mydata->name . "\n";
         foreach($mydata->values as $values)
         {
              echo $values->value . "\n";
         }
    }        

Chart.JS API has changed since this was posted and older examples did not seem to be working for me. here is an updated fiddle that works on the newer versions

HTML:

<body>
    <canvas id="canvas" height="450" width="600"></canvas>
    <img id="url" />
</body>

JS:

function done(){
  alert("haha");
  var url=myLine.toBase64Image();
  document.getElementById("url").src=url;
}

var options = {
  bezierCurve : false,
  animation: {
    onComplete: done
  }
};

var myLine = new 
   Chart(document.getElementById("canvas").getContext("2d"),
     {
        data:lineChartData,
        type:"line",
        options:options
      }
    );

You can't change your password through TortoiseSVN. Authentication to the SVN server has to be changed within the SVN server itself.

How you actually achieve this depends on which SVN Server is housing the repository and how the SVN Server was laid out on your computer.

n a Windows environment, credentials are typically stored in <yoursvnroot>\conf\passwd.

In a Linux environment it could be as above, or a myriad of other ways depending on how it's hosted.

Make all parent element with 100% width and 100% height and use display: table; and display:table-cell;, check the working sample.

I use setdefault() when I want a default value in an OrderedDict. There isn't a standard Python collection that does both, but there are ways to implement such a collection.

You've practically written the format yourself.

yourdate.ToString("yyyyMMddHHmmss")

• MM = two digit month
• mm = two digit minutes
• HH = two digit hour, 24 hour clock
• hh = two digit hour, 12 hour clock

Everything else should be self-explanatory.

You could create a simple batch script to do this for you:

TYPE %1 | MORE /P >%1.1
MOVE %1.1 %1

Then run <batch script name> <FILE> and <FILE> will be instantly converted to DOS line endings.

The top answers here work, but I found something more elegant in Michael Hampton's answer to a related question. The "new" (firewalld-0.3.9-11+) --runtime-to-permanent option to firewall-cmd lets you create runtime rules and test them out before making them permanent:

$ firewall-cmd --zone=<zone> --add-port=2888/tcp
<Test it out>
$ firewall-cmd --runtime-to-permanent

Or to revert the runtime-only changes:

$ firewall-cmd --reload

Also see Antony Nguyen's comment. Apparently firewall-cmd --reload may not work properly in some cases where rules have been removed. In that case, he suggests restarting the firewalld service:

$ systemctl restart firewalld

Easiest method to get just the total size is powershell, but still is limited by fact that pathnames longer than 260 characters are not included in the total

Instead of changing the COM port in Device manager, if you're using the Arduino software, I had to set the port in Tools > Port menu.

Here is a simple query containing coalesce -

select * from person where coalesce(addressId, ContactId) is null.

It will return the persons where both addressId and contactId are null.

coalesce function

• takes least two arguments.
• arguments must be of integer type.
• return the first non-null argument.

e.g.

• coalesce(null, 1, 2, 3) will return 1.
• coalesce(null, null) will return null.

You can raise a notice in Postgres as follows:

raise notice 'Value: %', deletedContactId;

Visual mode map example to add single quotes around a selected block of text:

:vnoremap qq <Esc>`>a'<Esc>`<i'<Esc>

The only difference is that you're creating an unnecessary promise when you do return Promise.resolve("bbb"). Returning a promise from an onFulfilled() handler kicks off promise resolution. That's how promise chaining works.

Suppose we have three anchor tags like ,

<a  href="ID=1" class="testClick">Test1.</a>
<br />
<a  href="ID=2" class="testClick">Test2.</a>
<br />
<a  href="ID=3" class="testClick">Test3.</a>

now in script

$(".testClick").click(function () {
        var anchorValue= $(this).attr("href");
        alert(anchorValue);
});

use this keyword instead of className (testClick)

Ok, if it doesn't matter which value in the non-duplicated column you select, this should be pretty easy:

dat <- data.frame(id=c(1,1,3),id2=c(1,1,4),somevalue=c("x","y","z"))
> dat[!duplicated(dat[,c('id','id2')]),]
  id id2 somevalue
1  1   1         x
3  3   4         z

Inside the duplicated call, I'm simply passing only those columns from dat that I don't want duplicates of. This code will automatically always select the first of any ambiguous values. (In this case, x.)

1. To convert and append an integer, use operator += (or member function concat):

   String stringOne = "A long integer: ";
   stringOne += 123456789;
   

2. To get the string as type char[], use toCharArray():

   char charBuf[50];
   stringOne.toCharArray(charBuf, 50)
   

In the example, there is only space for 49 characters (presuming it is terminated by null). You may want to make the size dynamic.

Overhead

The cost of bringing in String (it is not included if not used anywhere in the sketch), is approximately 1212 bytes program memory (flash) and 48 bytes RAM.

This was measured using Arduino IDE version 1.8.10 (2019-09-13) for an Arduino Leonardo sketch.

Here's one approach. Using a combination of the answers above do the following:

1. Convert cell to text using a predefined format
2. Try using DATEVALUE to convert it back to a date
3. Exclude any cells where DATEVALUE returns an error

As a formula, just use the example below with <> replaced with your range reference.

=SUM(IF(ISERROR(DATEVALUE(TEXT(<<RANGE HERE>>, "MM/dd/yyyy"))), 0, 1))

You must enter this as an array formula with CTRL + SHIFT + ENTER.

As I just came across this topic I wanted to share the reason and solution why I got the message "invalid or corrupt jarfile":

I had updated the version of the "maven-jar-plugin" in my pom.xml from 2.1 to 3.1.2. Everything still went fine and a jar file was built. But somehow it obviously wouldn't run anymore.

As soon as i set the "maven-jar-plugin" version back to 2.1 again, the problem was gone.

Before new gallery access in KitKat I got my real path in sdcard with this method

That was never reliable. There is no requirement that the Uri that you are returned from an ACTION_GET_CONTENT or ACTION_PICK request has to be indexed by the MediaStore, or even has to represent a file on the file system. The Uri could, for example, represent a stream, where an encrypted file is decrypted for you on the fly.

How could I manage to obtain the real path in sdcard?

There is no requirement that there is a file corresponding to the Uri.

Yes, I really need a path

Then copy the file from the stream to your own temporary file, and use it. Better yet, just use the stream directly, and avoid the temporary file.

I have changed my Intent.ACTION_GET_CONTENT for Intent.ACTION_PICK

That will not help your situation. There is no requirement that an ACTION_PICK response be for a Uri that has a file on the filesystem that you can somehow magically derive.

REST security is transport dependent while SOAP security is not.

REST inherits security measures from the underlying transport while SOAP defines its own via WS-Security.

When we talk about REST, over HTTP - all security measures applied HTTP are inherited and this is known as transport level security.

Transport level security, secures your message only while its on the wire - as soon as it leaves the wire, the message is no more secured.

But, with WS-Security, its message level security - even though the message leaves the transport channel it will be still protected. Also - with message level security you can partly encrypt the message [not the entire message, but only the parts you want] - but with transport level security you can't do it.

WS-Security has measures for authentication, integrity, confidentiality and non-repudiation while SSL doesn't support non repudiation [with 2-legged OAuth it does].

In performance-wise SSL is very much faster than WS-Security.

Thanks...

Andrew Whitaker's answer is true, but you can use any expression for any part.
Just remember the second (middle) expression should evaluate so it can be compared to a boolean true or false.

When I use a for loop, I think of it as

for (var i = 0; i < 10; ++i) {
    /* expression */
}

as being

var i = 0;
while( i < 10 ) {
    /* expression */
    ++i;
}

EL expression:

${requestScope.Error_Message}

There are several implicit objects in JSP EL. See Expression Language under the "Implicit Objects" heading.

On Debian I needed the following packages to fix this

To search google using API you should use Google Custom Search, scraping web page is not allowed

In java you can use CustomSearch API Client Library for Java

The maven dependency is:

<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-customsearch</artifactId>
    <version>v1-rev57-1.23.0</version>
</dependency> 

Example code searching using Google CustomSearch API Client Library

public static void main(String[] args) throws GeneralSecurityException, IOException {

    String searchQuery = "test"; //The query to search
    String cx = "002845322276752338984:vxqzfa86nqc"; //Your search engine

    //Instance Customsearch
    Customsearch cs = new Customsearch.Builder(GoogleNetHttpTransport.newTrustedTransport(), JacksonFactory.getDefaultInstance(), null) 
                   .setApplicationName("MyApplication") 
                   .setGoogleClientRequestInitializer(new CustomsearchRequestInitializer("your api key")) 
                   .build();

    //Set search parameter
    Customsearch.Cse.List list = cs.cse().list(searchQuery).setCx(cx); 

    //Execute search
    Search result = list.execute();
    if (result.getItems()!=null){
        for (Result ri : result.getItems()) {
            //Get title, link, body etc. from search
            System.out.println(ri.getTitle() + ", " + ri.getLink());
        }
    }

}

As you can see you will need to request an api key and setup an own search engine id, cx.

Note that you can search the whole web by selecting "Search entire web" on basic tab settings during setup of cx, but results will not be exactly the same as a normal browser google search.

Currently (date of answer) you get 100 api calls per day for free, then google like to share your profit.

Try to get some debugging information, could be that the file path is wrong, for example.

Try these two things:- Add this line to the top of your sample page:

<?php error_reporting(E_ALL);?>

This will print all errors/warnings/notices in the page so if there is any problem you get a text message describing it instead of a blank page

Additionally you can change include() to require()

<?php require ('headings.php'); ?>
<?php require ('navbar.php'); ?>
<?php require ('image.php'); ?>

This will throw a FATAL error PHP is unable to load required pages, and should help you in getting better tracing what is going wrong..

You can post the error descriptions here, if you get any, and you are unable to figure out what it means..
