Programs & Examples On #Project structure

Please go to Module settings and choose Modules from Project Settings then you need to Select src and gen folders and marked them as Source folders by right-click on them and select Source

I've seen this error a few times too, and I've always been able to solve it by correctly identifying the project's module settings. In IntelliJ, right-click on the top level project -> "Open Module Settings". This should open up a window with the entire project structure and content identified as "Source Folders", "Test Source Folders", etc. Make sure these are correctly set. For the "Source Folders", ensure that the folder is your src/ or src/java (or whatever your source language is), as the case may be

In my experience, it's just a matter of iteration. Put your data and code wherever you think they go. Chances are, you'll be wrong anyway. But once you get a better idea of exactly how things are going to shape up, you're in a much better position to make these kinds of guesses.

As far as extension sources, we have a Code directory under trunk that contains a directory for python and a directory for various other languages. Personally, I'm more inclined to try putting any extension code into its own repository next time around.

With that said, I go back to my initial point: don't make too big a deal out of it. Put it somewhere that seems to work for you. If you find something that doesn't work, it can (and should) be changed.

As already recommended, you can use tree. But for using it together with restructured text some additional parameters were required.

The standard tree output will not be printed if your're using pandoc to produce pdf.

tree --dirsfirst --charset=ascii /path/to/directory will produce a nice ASCII tree that can be integrated into your document like this:

Under a Linux environment you could do the following :

$ find <base_dir> -name *.jar -print0 | xargs -0 -l jar tf | grep <name>

Where name is the name of the class file that you are looking inside the jars distributed across the hierarchy of directories rooted at the base_dir.

Here is what I follow on My system.

1. All Projects: There is a projects directory in my home folder i.e. ~/projects. All the projects rest inside it.

2. Individual Project: I follow a standardized structure template used by many developers called django-skel for individual projects. It basically takes care of all your static file and media files and all.

3. Virtual environment: I have a virtualenvs folder inside my home to store all virtual environments in the system i.e. ~/virtualenvs . This gives me flexibility that I know what all virtual environments I have and can look use easily

The above 3 are the main partitions of My working environment.

All the other parts you mentioned are mostly dependent on project to project basis (i.e. you might use different databases for different projects). So they should reside in their individual projects.

Try this

function setAttribs(elm, ob) {
    //var r = [];
    //var i = 0;
    for (var z in ob) {
        if (ob.hasOwnProperty(z)) {
            try {
                elm[z] = ob[z];
            }
            catch (er) {
                elm.setAttribute(z, ob[z]);
            }
        }
    }
    return elm;
}

This question has been asked long ago but none of the answers above helped me out, though Milad Moosavi`s answer was very close. To open a new activity from a certain position on the recycler view, the following code may help:

    @Override
    public void onBindViewHolder(@NonNull TripViewHolder holder, int position) {
        Trip currentTrip = trips.get(position);

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent = new Intent(v.getContext(), EditTrip.class);
                v.getContext().startActivity(intent);
            }
        });

        holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {
                Intent intent = new Intent(v.getContext(), ReadTripActivity.class);
                v.getContext().startActivity(intent);

                return false;
            }
        });
    }

Your DOS command 2> nul

Read page Using command redirection operators. Besides the "2>" construct mentioned by Tanuki Software, it lists some other useful combinations.

I found it short and simple, and can be tested in Dev Tool console itself.

$('#id option').each( (index,element)=>console.log( index : ${index}, value : ${element.value}, text : ${element.text}) )

This should solve your problem:

select replace(to_char(a, '90D90'),'.00','')
from
(
select 50 a from dual
union
select 50.57 from dual
union
select 5.57 from dual
union
select 0.35 from dual
union
select 0.4 from dual
);

Give a look also as this SQL Fiddle for test.

Search your code for occurrences of new, and make sure that they all occur within a constructor with a matching delete in a destructor. Make sure that this is the only possibly throwing operation in that constructor. A simple way to do this is to wrap all pointers in std::auto_ptr, or boost::scoped_ptr (depending on whether or not you need move semantics). For all future code just ensure that every resource is owned by an object that cleans up the resource in its destructor. If you need move semantics then you can upgrade to a compiler that supports r-value references (VS2010 does I believe) and create move constructors. If you don't want to do that then you can use a variety of tricky techniques involving conscientious usage of swap, or try the Boost.Move library.

For a simple copy-tasks I can recommend copy-rename-maven-plugin. It's straight forward and simple to use:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>com.coderplus.maven.plugins</groupId>
        <artifactId>copy-rename-maven-plugin</artifactId>
        <version>1.0</version>
        <executions>
          <execution>
            <id>copy-file</id>
            <phase>generate-sources</phase>
            <goals>
              <goal>copy</goal>
            </goals>
            <configuration>
              <sourceFile>src/someDirectory/test.environment.properties</sourceFile>
              <destinationFile>target/someDir/environment.properties</destinationFile>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

If you would like to copy more than one file, replace the <sourceFile>...</destinationFile> part with

<fileSets>
  <fileSet>
    <sourceFile>src/someDirectory/test.environment.properties</sourceFile>
    <destinationFile>target/someDir/environment.properties</destinationFile>
  </fileSet>
  <fileSet>
    <sourceFile>src/someDirectory/test.logback.xml</sourceFile>
    <destinationFile>target/someDir/logback.xml</destinationFile>
  </fileSet>                
</fileSets>

Furthermore you can specify multiple executions in multiple phases if needed, the second goal is "rename", which simply does what it says while the rest of the configuration stays the same. For more usage examples refer to the Usage-Page.

Note: This plugin can only copy files, not directories. (Thanks to @james.garriss for finding this limitation.)

Python is looking for the a object within your a.py module.

Either RENAME that file to something else or use

from __future__ import absolute_import 

at the top of your a.py module.

This is the required source code :

public static void openKeypad(final Context context, final View v) 
 {
new Handler().postDelayed(new Runnable() 
{
    @Override
    public void run() 
    {
        InputMethodManager inputManager =   (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE); 
        inputManager.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);    
        Log.e("openKeypad", "Inside Handler");
    }
},300);}

For details , Please go through this link. This helped me. https://github.com/Nikhillosalka/Keyboard/blob/master/README.md

How about a one-liner list of digits...

ldigits = lambda n, l=[]: not n and l or l.insert(0,n%10) or ldigits(n/10,l)

This works for me:

<script type="text/javascript">
function change(){
    document.getElementById("submit").disabled = false;
}
</script>

The existing answers are a little too verbose so I created this smaller, auto-matching version.

function prefered_language(array $available_languages, $http_accept_language) {

    $available_languages = array_flip($available_languages);

    $langs;
    preg_match_all('~([\w-]+)(?:[^,\d]+([\d.]+))?~', strtolower($http_accept_language), $matches, PREG_SET_ORDER);
    foreach($matches as $match) {

        list($a, $b) = explode('-', $match[1]) + array('', '');
        $value = isset($match[2]) ? (float) $match[2] : 1.0;

        if(isset($available_languages[$match[1]])) {
            $langs[$match[1]] = $value;
            continue;
        }

        if(isset($available_languages[$a])) {
            $langs[$a] = $value - 0.1;
        }

    }
    arsort($langs);

    return $langs;
}

And the sample usage:

//$_SERVER["HTTP_ACCEPT_LANGUAGE"] = 'en-us,en;q=0.8,es-cl;q=0.5,zh-cn;q=0.3';

// Languages we support
$available_languages = array("en", "zh-cn", "es");

$langs = prefered_language($available_languages, $_SERVER["HTTP_ACCEPT_LANGUAGE"]);

/* Result
Array
(
    [en] => 0.8
    [es] => 0.4
    [zh-cn] => 0.3
)*/

In WPF apps This code working perfectly

private void txt1_KeyDown(object sender, KeyEventArgs e)
  {
     if (Keyboard.IsKeyDown(Key.Enter) )
         {
              Button_Click(this, new RoutedEventArgs());
         }
   }

This is difficult to achieve, but the cookie expiration date can be set in another cookie. This cookie can then be read later to get the expiration date. Maybe there is a better way, but this is one of the methods to solve your problem.

Have you tried using an iFrame? No ajax, and the original page will not load.

You can display the submit form as a separate page inside the iframe, and when it gets submitted the outer/container page will not reload. This solution will not make use of any kind of ajax.

# COLUMN is integer column number
# INPUT_FILE is input file name

cut -f ${COLUMN} < ${INPUT_FILE} | sort -u | wc -l

All you have to do set a variable for x then just type this in before the return 0;

cout<<"\nPress any key and hit enter to end...";
cin>>x;

Generally there are two ways to do it, a converter class or a property in the Viewmodel that essentially converts the value for you.

I tend to use the property approach if it is a one off conversion. If you want to reuse it, use the converter. Below, find an example of the converter:

<ValueConversion(GetType(Boolean), GetType(Visibility))> _
Public Class BoolToVisibilityConverter
    Implements IValueConverter

    Public Function Convert(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.Convert

        If value IsNot Nothing Then
            If value = True Then 
                Return Visibility.Visible
            Else
                Return Visibility.Collapsed
            End If
        Else
            Return Visibility.Collapsed
        End If
    End Function

    Public Function ConvertBack(ByVal value As Object, ByVal targetType As System.Type, ByVal parameter As Object, ByVal culture As System.Globalization.CultureInfo) As Object Implements System.Windows.Data.IValueConverter.ConvertBack
        Throw New NotImplementedException
    End Function
End Class

A ViewModel property method would just check the boolean property value, and return a visibility based on that. Be sure to implement INotifyPropertyChanged and call it on both the Boolean and Visibility properties to updated properly.

I would suggest you using my method to get a resource ID. It's Much more efficient, than using getIdentidier() method, which is slow.

Here's the code:

/**
 * @author Lonkly
 * @param variableName - name of drawable, e.g R.drawable.<b>image</b>
 * @param ? - class of resource, e.g R.drawable.class or R.raw.class
 * @return integer id of resource
 */
public static int getResId(String variableName, Class<?> ?) {

    Field field = null;
    int resId = 0;
    try {
        field = ?.getField(variableName);
        try {
            resId = field.getInt(null);
        } catch (Exception e) {
            e.printStackTrace();
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
    return resId;

}

Undoing a merge with git is so easy you shouldn't even worry about the dry run:

$ git pull $REMOTE $BRANCH
# uh oh, that wasn't right
$ git reset --hard ORIG_HEAD
# all is right with the world

EDIT: As noted in the comments below, if you have changes in your working directory or staging area you'll probably want to stash them before doing the above (otherwise they will disappear following the git reset above)

the data object is a buffer of bytes. Simply call .toString() to get human-readable code:

console.log( data.toString() );

reference: Node.js buffers

Well, even the SELECT COUNT(*) FROM Table will be fairly inefficient, especially on large tables, since SQL Server really can't do anything but do a full table scan (clustered index scan).

Sometimes, it's good enough to know an approximate number of rows from the database, and in such a case, a statement like this might suffice:

SELECT 
    SUM(used_page_count) * 8 AS SizeKB,
    SUM(row_count) AS [RowCount], 
    OBJECT_NAME(OBJECT_ID) AS TableName
FROM 
    sys.dm_db_partition_stats
WHERE 
    OBJECT_ID = OBJECT_ID('YourTableNameHere')
    AND (index_id = 0 OR index_id = 1)
GROUP BY 
    OBJECT_ID

This will inspect the dynamic management view and extract the number of rows and the table size from it, given a specific table. It does so by summing up the entries for the heap (index_id = 0) or the clustered index (index_id = 1).

It's quick, it's easy to use, but it's not guaranteed to be 100% accurate or up to date. But in many cases, this is "good enough" (and put much less burden on the server).

Maybe that would work for you, too? Of course, to use it in EF, you'd have to wrap this up in a stored proc or use a straight "Execute SQL query" call.

Did you compile with Eclipse? It uses a different compiler (not javac). That should not result in this error (if everything is configured properly), but you can try to compile it with javac instead.

If that fixed the problem, try to see if Eclipse has some incorrect compiler settings. Specifically have it target Java 5.

In some cases, it might be a bad idea to first add the column to the DataGridView and then hide it.

I for example have a class that has an NHibernate proxy for an Image property for company logos. If I accessed that property (e.g. by calling its ToString method to show that in a DataGridView), it would download the image from the SQL server. If I had a list of Company objects and used that as the dataSource of the DataGridView like that, then (I suspect) it would download ALL the logos BEFORE I could hide the column.

To prevent this, I used the custom attribute

 [System.ComponentModel.Browsable(false)]

on the image property, so that the DataGridView ignores the property (doesn't create the column and doesn't call the ToString methods).

 public class Company
 {
     ...
     [System.ComponentModel.Browsable(false)]
     virtual public MyImageClass Logo { get; set;}

if you have only two "kinds" of column styles - use one as TD and one as TH. Then, declare a class for the table and a sub-class for that table's THs and TDs. Then your HTML can be super efficient.

I had this same issue , but after a couple of research I fond it out it's quite simple to do,

Locate this URL in your Codeigniter project: application/helpers/util_helper.php

add this below code

//you can define any kind of function but I have queried database in my case

//check if the function exist
 if (!function_exists('yourfunctionname')) {
    function yourfunctionname($param (if neccesary)) {
        
        //get the instance
        $ci = & get_instance();
    
        // write your query with the instance class

        $data =  $ci->db->select('*');
        $data =  $ci->db->from('table');  
        $data =  $ci->db->where('something', 'something');

        //you can return anythting

        $data =  $ci->db->get()->num_rows(); 

        if ($data > 0) {
            return $data;
        }  else {
            return 0;
        }  
    }
}

I know this is an ancient question, but I just thought that I'd weigh in.

I'm using disableScroll. Simple and it works like in a dream.

I have had some trouble disabling scroll on body, but allowing it on child elements (like a modal or a sidebar). It looks like that something can be done using disableScroll.on([element], [options]);, but I haven't gotten that to work just yet.

The reason that this is prefered compared to overflow: hidden; on body is that the overflow-hidden can get nasty, since some things might add overflow: hidden; like this:

... This is good for preloaders and such, since that is rendered before the CSS is finished loading.

But it gives problems, when an open navigation should add a class to the body-tag (like <body class="body__nav-open">). And then it turns into one big tug-of-war with overflow: hidden; !important and all kinds of crap.

From the Android docs (March 2016):

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

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

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

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

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

The accepted answer didn't work for me on Internet Explorer 9. I checked it and the browser detection was not working properly, it detected ff (firefox) when i was at Internet Explorer.

I just did this change:

if ($.browser.msie) 

Instead of:

if (br == "ie") { 

The resulting code is this one:

function insertAtCaret(areaId,text) {
    var txtarea = document.getElementById(areaId);
    var scrollPos = txtarea.scrollTop;
    var strPos = 0;
    var br = ((txtarea.selectionStart || txtarea.selectionStart == '0') ? 
        "ff" : (document.selection ? "ie" : false ) );

    if ($.browser.msie) { 
        txtarea.focus();
        var range = document.selection.createRange();
        range.moveStart ('character', -txtarea.value.length);
        strPos = range.text.length;
    }
    else if (br == "ff") strPos = txtarea.selectionStart;

    var front = (txtarea.value).substring(0,strPos);  
    var back = (txtarea.value).substring(strPos,txtarea.value.length); 
    txtarea.value=front+text+back;
    strPos = strPos + text.length;
    if (br == "ie") { 
        txtarea.focus();
        var range = document.selection.createRange();
        range.moveStart ('character', -txtarea.value.length);
        range.moveStart ('character', strPos);
        range.moveEnd ('character', 0);
        range.select();
    }
    else if (br == "ff") {
        txtarea.selectionStart = strPos;
        txtarea.selectionEnd = strPos;
        txtarea.focus();
    }
    txtarea.scrollTop = scrollPos;
}

you should convert test type >>>> test.tostring();

change the last line to this :

Label1.Text = "Du har nu lånat filmen:" + test.tostring();

This will get what you want in plain JS.

var el = document.getElementById('*spaM4');
text = (el.innerText || el.textContent);

FIDDLE

If all you are trying to do is get the value out of the hashmap itself, you can do something like the following:

for (Object key : map.keySet()) {
    Object value = map.get(key);
    //TODO: this
}

Or, you can iterate over the entries of a map, if that is what you are interested in:

for (Map.Entry<Object, Object> entry : map.entrySet()) {
    Object key = entry.getKey();
    Object value = entry.getValue();
    //TODO: other cool stuff
}

As a community, we might be able to give you better/more appropriate answers if we had some idea why you needed the indexes or what you thought the indexes could do for you.

In addition to all the answers above:

If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having

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

in your manifest won't be enough. You also have actively request the permission in your activity:

//check for permission
if(ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
    //ask for permission
    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}

I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request

I've not tried to run below, though. I think this's a tricky way.

map{print $_;} @array;

There is another option by using zip4j at https://github.com/srikanth-lingala/zip4j

Creating a zip file with single file in it / Adding single file to an existing zip

new ZipFile("filename.zip").addFile("filename.ext"); Or

new ZipFile("filename.zip").addFile(new File("filename.ext"));

Creating a zip file with multiple files / Adding multiple files to an existing zip

new ZipFile("filename.zip").addFiles(Arrays.asList(new File("first_file"), new File("second_file")));

Creating a zip file by adding a folder to it / Adding a folder to an existing zip

new ZipFile("filename.zip").addFolder(new File("/user/myuser/folder_to_add"));

Creating a zip file from stream / Adding a stream to an existing zip new ZipFile("filename.zip").addStream(inputStream, new ZipParameters());

Try the <wbr> tag - not as elegant as the word-wrap property that others suggested, but it's a working solution until all major browsers (read IE) implement CSS3.

Although the answer that Gunter posted was correct, it is not different than what I already had posted. The problem was not the ENV directive, but the subsequent instruction RUN export $PATH

There's no need to export the environment variables, once you have declared them via ENV in your Dockerfile.

As soon as the RUN export ... lines were removed, my image was built successfully

I am working on an angular js app, andhavecome across a similar issue. What i did was display the image from the db, then created a button to remove or keep the current image. If the user decided to keep the current image, i changed the ng-submit attribute to another function whihc doesnt require image validation, and updated the record in the db without touching the original image path name. The remove image function also changed the ng-submit attribute value back to a function that submits the form and includes image validation and upload. Also a bit of javascript to slide the into view to upload a new image.

Short answer: Why not?

Longer answer: The time itself doesn't really matter, as long as everyone who uses it agrees on its value. As 1/1/70 has been in use for so long, using it will make you code as understandable as possible for as many people as possible.

There's no great merit in choosing an arbitrary epoch just to be different.

I suggest you also take a look at __autoload.
This will clean up the code of requires and includes.

Enhanced for loop:

for (String element : array) {

    // rest of code handling current element
}

Traditional for loop equivalent:

for (int i=0; i < array.length; i++) {
    String element = array[i]; 

    // rest of code handling current element
}

Terminal: Focus Next Terminal

Or add the following key shortcut and do it faster with keyboard combination.

  {
    "key": "alt+cmd+right",
    "command": "workbench.action.terminal.focusNext",
    "when": "terminalFocus"
  },
  {
    "key": "alt+cmd+left",
    "command": "workbench.action.terminal.focusPrevious",
    "when": "terminalFocus"
  },

There's at least one situation in which you want sys.stdout instead of print.

When you want to overwrite a line without going to the next line, for instance while drawing a progress bar or a status message, you need to loop over something like

Note carriage return-> "\rMy Status Message: %s" % progress

And since print adds a newline, you are better off using sys.stdout.

Keep in mind that most of the techniques here are valid presuming that round-off error due to prior calculations is not a factor. E.g. you could use roundf, like this:

float z = 1.0f;

if (roundf(z) == z) {
    printf("integer\n");
} else {
    printf("fraction\n");
}

The problem with this and other similar techniques (such as ceilf, casting to long, etc.) is that, while they work great for whole number constants, they will fail if the number is a result of a calculation that was subject to floating-point round-off error. For example:

float z = powf(powf(3.0f, 0.05f), 20.0f);

if (roundf(z) == z) {
    printf("integer\n");
} else {
    printf("fraction\n");
}

Prints "fraction", even though (3^1/20)²⁰ should equal 3, because the actual calculation result ended up being 2.9999992847442626953125.

Any similar method, be it fmodf or whatever, is subject to this. In applications that perform complex or rounding-prone calculations, usually what you want to do is define some "tolerance" value for what constitutes a "whole number" (this goes for floating-point equality comparisons in general). We often call this tolerance epsilon. For example, lets say that we'll forgive the computer for up to +/- 0.00001 rounding error. Then, if we are testing z, we can choose an epsilon of 0.00001 and do:

if (fabsf(roundf(z) - z) <= 0.00001f) {
    printf("integer\n");
} else {
    printf("fraction\n");
}

You don't really want to use ceilf here because e.g. ceilf(1.0000001) is 2 not 1, and ceilf(-1.99999999) is -1 not -2.

You could use rintf in place of roundf if you prefer.

Choose a tolerance value that is appropriate for your application (and yes, sometimes zero tolerance is appropriate). For more information, check out this article on comparing floating-point numbers.

<property attribute="attributeValue">proopertyValue</property>

would be one way to look at it.

In C#

[Attribute]
public class Entity
{
    private int Property{get; set;};

You can use the fixed CSS position property to accomplish this. There is a basic tutorial on this here.

EDIT: However, this approach is NOT supported in IE versions < IE7, and only in IE7 if it is in standards mode. This is discussed in a little more detail here.

There is also a hack, explained here, that shows how to accomplish fixed positioning in IE6 without affecting absolute positioning. What version of IE are you targeting your website for?

One interesting difference in ng-if and ng-show is:

SECURITY

DOM elements present in ng-if block will not be rendered in case of its value as false

where as in case of ng-show, the user can open your Inspect Element Window and set its value to TRUE.

And with a whoop, whole contents that was meant to be hidden gets displayed, which is a security breach. :)

Separate with commas:

http://localhost:8080/MovieDB/GetJson?name=Actor1,Actor2,Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name=Actor1&name=Actor2&name=Actor3&startDate=20120101&endDate=20120505

or:

http://localhost:8080/MovieDB/GetJson?name[0]=Actor1&name[1]=Actor2&name[2]=Actor3&startDate=20120101&endDate=20120505

Either way, your method signature needs to be:

@RequestMapping(value = "/GetJson", method = RequestMethod.GET) 
public void getJson(@RequestParam("name") String[] ticker, @RequestParam("startDate") String startDate, @RequestParam("endDate") String endDate) {
   //code to get results from db for those params.
 }

One way is to use the code Gamlet posted in his answer:

• Save it as curl.php

• Then in your file:

  require 'curl.php';
  
  $photo="https://graph.facebook.com/me/picture?access_token=" . $session['access_token'];
  $sample = new sfFacebookPhoto;
  $thephotoURL = $sample->getRealUrl($photo);
  echo $thephotoURL;
  

I thought I would post this, because it took me a bit of time to figure out the particulars... Even though profile pictures are public, you still need to have an access token in there to get it when you curl it.

I had similar issue, trying to load data from Excel spreadsheet; and was running on WinX64. So I went VS BI`s project properties: Configuration Properties \ Dbugging and Switch Run64BitRuntime from True to False. It worked.

This seems to be the best solution I’ve found to this problem, as long as your browser supports the ::before pseudo element: CSS-Tricks: Centering in the Unknown.

It doesn’t require any extra markup and seems to work extremely well. I couldn’t use the display: table method because table elements don’t obey the max-height property.

.block {_x000D_
  height: 300px;_x000D_
  text-align: center;_x000D_

  border: #a0a0a0 solid 1px;_x000D_
  background: #f5f5f5;_x000D_
}

<div class="block">_x000D_
    <div class="centered">_x000D_
        <h1>Some text</h1>_x000D_
        <p>But he stole up to us again, and suddenly clapping his hand on my_x000D_
           shoulder, said&mdash;"Did ye see anything looking like men going_x000D_

Just for the sake of completeness, here is another very simple solution, which will most likely take a very long time to run, but uses very little memory.

Let all possible integers be the range from int_min to int_max, and bool isNotInFile(integer) a function which returns true if the file does not contain a certain integer and false else (by comparing that certain integer with each integer in the file)

for (integer i = int_min; i <= int_max; ++i)
{
    if (isNotInFile(i)) {
        return i;
    }
}

<!doctype html>
<html>
<body>
<p id = "myString">zyxtspqnmdba</p>
<p id = "orderedString"></p>
<script>
var myString = document.getElementById("myString").innerHTML;
orderString(myString);
function orderString(str) {
    var i = 0;
    var myArray = str.split("");
    while (i < str.length){
        var j = i + 1;
        while (j < str.length) {
            if (myArray[j] < myArray[i]){
                var temp = myArray[i];
                myArray[i] = myArray[j];
                myArray[j] = temp;
            }
            j++;
        }
        i++;
    }
    var newString = myArray.join("");
    document.getElementById("orderedString").innerHTML = newString;
}
</script>
</body>
</html>

See django docs for views.login(), you supply a 'next' value (as a hidden field) on the input form to redirect to after a successful login.

6 years later... I found this post and I liked more the numpy aproach:

import numpy as np
dates_array = np.array(['2013-01-01', '2013-01-15', '2013-01-30']).astype('datetime64[ns]')
truncated_dates = dates_array.astype('datetime64[D]')

For API level >= 28 available attribute android:dialogCornerRadius . To support previous API versions need use

To highlight patterns while viewing the whole file, h can do this.

Plus it uses different colors for different patterns.

cat FILE | h 'PAT1' 'PAT2' ...

You can also pipe the output of h to less -R for better reading.

To grep and use 1 color for each pattern, cxpgrep could be a good fit.

Following is the best way to get of the issue , check following on classpath:

1. Make sure JAVA_HOME system variable must have till jdk e.g C:\Program Files\Java\jdk1.7.0_80 , don't append bin here.

2. Because MAVEN will look for jre which is under C:\Program Files\Java\jdk1.7.0_80

3. Set %JAVA_HOME%\bin in classpath .

Then try Maven version .

Hope it will help .

It would work giving the #container div width:80% (any width less than the main content and have given in %, so that it manages well from both left and right) and giving margin:0px auto; or margin:0 auto; (both work fine).

Check this: USING FOR LOOP

for a in range(5):
    x='A'
    val=chr(ord(x) + a)
    print(val)

LOOP OUTPUT: A B C D E

You need a section in your file:

[My Section]
path1 = D:\test1\first
path2 = D:\test2\second
path3 = D:\test2\third

Then, read the properties:

import ConfigParser

config = ConfigParser.ConfigParser()
config.readfp(open(r'abc.txt'))
path1 = config.get('My Section', 'path1')
path2 = config.get('My Section', 'path2')
path3 = config.get('My Section', 'path3')

Another easy way is to use:

mysqladmin debug 

This dumps a lot of information (including locks) to the error log.

$url = "http://www.example/images/image.gif";
$save_name = "image.gif";
$save_directory = "/var/www/example/downloads/";

if(is_writable($save_directory)) {
    file_put_contents($save_directory . $save_name, file_get_contents($url));
} else {
    exit("Failed to write to directory "{$save_directory}");
}

Simple solution for downloading a file from the server:

protected void btnDownload_Click(object sender, EventArgs e)
        {
            string FileName = "Durgesh.jpg"; // It's a file name displayed on downloaded file on client side.

            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            response.ContentType = "image/jpeg";
            response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
            response.TransmitFile(Server.MapPath("~/File/001.jpg"));
            response.Flush();
            response.End();
        }

I use $response->getBody()->getContents() to get JSON from response. Guzzle version 6.3.0.

You need to include angular-route.js in your HTML:

<script src="angular-route.js">

http://docs.angularjs.org/api/ngRoute

The "error_page" parameter makes a redirect, converting the request method to "GET", it is not a custom response page.

The easiest solution is

     server{
         root /var/www/html;
         location ~ \.php {
            if (!-f $document_root/$fastcgi_script_name){
                return 404;
            }
            fastcgi_pass   127.0.0.1:9000;
            include fastcgi_params.default;
            fastcgi_param  SCRIPT_FILENAME  $document_root/$fastcgi_script_name;
        }

By the way, if you want Nginx to process 404 status returned by PHP scripts, you need to add

[fastcgi_intercept_errors][1] on;

E.g.

     location ~ \.php {
            #...
            error_page  404   404.html;
            fastcgi_intercept_errors on;
         }

It's not really a cheat-sheet, but for me I setup a 'java' search keyword in Google Chrome to search over the javadoc, using site:<javadoc_domain_here>.

You could do the same but also add the domain for the Sun Java Tutorial and for several Java FAQ sites and you'd be OK.

Otherwise, StackOverflow is a pretty good cheat-sheet :)

Based on this HTML5 Doctor diagram, I'm thinking this may be the best markup:

<aside class="sidebar">
    <article id="widget_1" class="widget">...</article>
    <article id="widget_2" class="widget">...</article>
    <article id="widget_3" class="widget">...</article>
</aside> <!-- end .sidebar -->

I think it's clear that <aside> is the appropriate element as long as it's outside the main <article> element.

Now, I'm thinking that <article> is also appropriate for each widget in the aside. In the words of the W3C:

The article element represents a self-contained composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.

navigate to the folder where you have installed your kibana if you have used yum to install kibana it will be placed in following location by default

/usr/share/kibana

then use the following command

bin/kibana --version

Laravel is not actually that slow. 500-1000ms is absurd; I got it down to 20ms in debug mode.

The problem was Vagrant/VirtualBox + shared folders. I didn't realize they incurred such a performance hit. I guess because Laravel has so many dependencies (loads ~280 files) and each of those file reads is slow, it adds up really quick.

kreeves pointed me in the right direction, this blog post describes a new feature in Vagrant 1.5 that lets you rsync your files into the VM rather than using a shared folder.

There's no native rsync client on Windows, so you'll have to use cygwin. Install it, and make sure to check off Net/rsync. Add C:\cygwin64\bin to your paths. [Or you can install it on Win10/Bash]

Vagrant introduces the new feature. I'm using Puphet, so my Vagrantfile looks a bit funny. I had to tweak it to look like this:

  data['vm']['synced_folder'].each do |i, folder|
    if folder['source'] != '' && folder['target'] != '' && folder['id'] != ''
      config.vm.synced_folder "#{folder['source']}", "#{folder['target']}", 
        id: "#{folder['id']}", 
        type: "rsync",
        rsync__auto: "true",
        rsync__exclude: ".hg/"
    end
  end

Once you're all set up, try vagrant up. If everything goes smoothly your machine should boot up and it should copy all the files over. You'll need to run vagrant rsync-auto in a terminal to keep the files up to date. You'll pay a little bit in latency, but for 30x faster page loads, it's worth it!

If you're using PhpStorm, it's auto-upload feature works even better than rsync. PhpStorm creates a lot of temporary files which can trip up file watchers, but if you let it handle the uploads itself, it works nicely.

One more option is to use lsyncd. I've had great success using this on Ubuntu host -> FreeBSD guest. I haven't tried it on a Windows host yet.

For Intellij IDEA Community 2019.1 you will need to follow these steps :

File -> New -> Edit File Templates.. -> Class -> /* Created by ${USER} on ${DATE} */

There's at least 7 different ways to test if a number is odd or even. But, if you read through these benchmarks, you'll find that as TGH mentioned above, the modulus operation is the fastest:

if (x % 2 == 0)
               //even number
        else
               //odd number

Here are a few other methods (from the website) :

//bitwise operation
if ((x & 1) == 0)
       //even number
else
      //odd number

//bit shifting
if (((x >> 1) << 1) == x)
       //even number
else
       //odd number

//using native library
System.Math.DivRem((long)x, (long)2, out outvalue);
if ( outvalue == 0)
       //even number
else
       //odd number

The answer to your question is actually two-fold. First of all you need to specify what you intend to do with the rendered HTML: save it to a new PDF file, or use it within another rendering context (i.e. add it to some other document you are generating).

The former is relatively easily accomplished using the Flying Saucer framework, which can be found here: https://github.com/flyingsaucerproject/flyingsaucer

The latter is actually a much more comprehensive problem that needs to be categorized further. Using iText you won't be able to (trivially, at least) combine iText elements (i.e. Paragraph, Phrase, Chunk and so on) with the generated HTML. You can hack your way out of this by using the ContentByte's addTemplate method and generating the HTML to this template.

If you on the other hand want to stamp the generated HTML with something like watermarks, dates or the like, you can do this using iText.

So bottom line: You can't trivially integrate the rendered HTML in other pdf generating contexts, but you can render HTML directly to a blank PDF document.

If you want to find the rows that are duplicated you can use find_duplicates from hablar:

library(dplyr)
library(hablar)

df <- tibble(a = c(1, 2, 2, 4),
             b = c(5, 2, 2, 8))

df %>% find_duplicates()

For CentOS, run this: sudo yum install libXext libSM libXrender

Try

<p:panelGrid styleClass="ui-noborder">

I used the Multiple SCMs Plugin in conjunction with the Git Plugin successfully with Jenkins.

If this function is in a module/class, you could just write them outside of the function, so it has Global Scope. Global Scope means the variable can be accessed by another function in the same module/class (if you use dim as declaration statement, use public if you want the variables can be accessed by all function in all modules) :

Dim iRaw As Integer
Dim iColumn As Integer

Function find_results_idle()
    iRaw = 1
    iColumn = 1
End Function

Function this_can_access_global()
    iRaw = 2
    iColumn = 2
End Function

var time = 0;
var time_framerate = 1000; //in milliseconds

function animate(timestamp) {
  if(timestamp > time + time_framerate) {
    time = timestamp;    

    //your code
  }

  window.requestAnimationFrame(animate);
}

You may be overcomplicating things, is there any reason you need the stringr package?

 df <- data.frame(Date = c("10/9/2009 0:00:00", "10/15/2009 0:00:00"))
 as.Date(df$Date, "%m/%d/%Y %H:%M:%S")

[1] "2009-10-09" "2009-10-15"

More generally and if you need the time component as well, use strptime:

strptime(df$Date, "%m/%d/%Y %H:%M:%S")

I'm guessing at what your actual data might look at from the partial results you give.

Late to the party but for anyone who wants to make 2 borders (on the bottom and right in my case) you can use the technique in the accepted answer and add an :after psuedo-element for the second line then just change the properties like so: http://jsfiddle.net/oeaL9fsm/

div
{
  width:500px;
  height:500px;   
  position: relative;
  z-index : 1;
}
div:before {
  content : "";
  position: absolute;
  left    : 25%;
  bottom  : 0;
  height  : 1px;
  width   : 50%;
  border-bottom:1px solid magenta;
}
div:after {
  content : "";
  position: absolute;
  right    : 0;
  bottom  : 25%;
  height  : 50%;
  width   : 1px;
  border-right:1px solid magenta;
}

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

The Problem is the "as string" in your function. Replace it with "as double" or "as long" to make it work. This way it even works if the last row is bigger than the "large number" proposed in the accepted answer.

So this should work

Function ultimaFilaBlanco(col As double) As Long        
    Dim lastRow As Long
    With ActiveSheet
        lastRow = ActiveSheet.Cells(ActiveSheet.Rows.Count, col).End(xlUp).row
    End With            
    ultimaFilaBlanco = lastRow          
End Function

Just for the sake of completeness, we can use the operators [ and [[:

set.seed(1)
df <- data.frame(v1 = runif(10), v2 = letters[1:10])

Several options

df[df[1] < 0.5 | df[2] == "g", ] 
df[df[[1]] < 0.5 | df[[2]] == "g", ] 
df[df["v1"] < 0.5 | df["v2"] == "g", ]

df$name is equivalent to df[["name", exact = FALSE]]

Using dplyr:

library(dplyr)
filter(df, v1 < 0.5 | v2 == "g")

Using sqldf:

library(sqldf)
sqldf('SELECT *
      FROM df 
      WHERE v1 < 0.5 OR v2 = "g"')

Output for the above options:

          v1 v2

You can use in this manner also

var rowId =$("#list").jqGrid('getGridParam','selrow');  
var rowData = jQuery("#list").getRowData(rowId);
var colData = rowData['UserId'];   // perticuler Column name of jqgrid that you want to access

Personally I would like to use regular expression here. Bellow code perfectly worked for me.

$baseUrl     = url('/'); // for my case https://www.xrepeater.com
$posted_url  = "home";
// Test with one by one
/*$posted_url  = "/home";
$posted_url  = "xrepeater.com";
$posted_url  = "www.xrepeater.com";
$posted_url  = "http://www.xrepeater.com";
$posted_url  = "https://www.xrepeater.com";
$posted_url  = "https://xrepeater.com/services";
$posted_url  = "xrepeater.dev/home/test";
$posted_url  = "home/test";*/

$regularExpression  = "((https?|ftp)\:\/\/)?"; // SCHEME Check
$regularExpression .= "([a-z0-9+!*(),;?&=\$_.-]+(\:[a-z0-9+!*(),;?&=\$_.-]+)?@)?"; // User and Pass Check
$regularExpression .= "([a-z0-9-.]*)\.([a-z]{2,3})"; // Host or IP Check
$regularExpression .= "(\:[0-9]{2,5})?"; // Port Check
$regularExpression .= "(\/([a-z0-9+\$_-]\.?)+)*\/?"; // Path Check
$regularExpression .= "(\?[a-z+&\$_.-][a-z0-9;:@&%=+\/\$_.-]*)?"; // GET Query String Check
$regularExpression .= "(#[a-z_.-][a-z0-9+\$_.-]*)?"; // Anchor Check

if(preg_match("/^$regularExpression$/i", $posted_url)) { 
    if(preg_match("@^http|https://@i",$posted_url)) {
        $final_url = preg_replace("@(http://)+@i",'http://',$posted_url);
        // return "*** - ***Match : ".$final_url;
    }
    else { 
          $final_url = 'http://'.$posted_url;
          // return "*** / ***Match : ".$final_url;
         }
    }
else {
     if (substr($posted_url, 0, 1) === '/') { 
         // return "*** / ***Not Match :".$final_url."<br>".$baseUrl.$posted_url;
         $final_url = $baseUrl.$posted_url;

I am totally unable to connect to localdb with any tool including MSSMA, sqlcmd, etc. You would think Microsoft would document this, but I find nothing on MSDN. I have v12 and tried (localdb)\v12.0 and that didn't work. Issuing the command sqllocaldb i MSSQLLocalDB shows that the local instance is running, but there is no way to connect to it.

c:\> sqllocaldb i MSSQLLocalDB

I finally figured it out!! the connect string is (localdb)\MSSQLLocalDB, e.g.:

The only way of having a variable which hasn't been assigned a value in C# is for it to be a local variable - in which case at compile-time you can tell that it isn't definitely assigned by trying to read from it :)

I suspect you really want Nullable<DateTime> (or DateTime? with the C# syntactic sugar) - make it null to start with and then assign a normal DateTime value (which will be converted appropriately). Then you can just compare with null (or use the HasValue property) to see whether a "real" value has been set.

You can also use it like this:

<div style="width: 60%; margin: 0px auto;">
    Your contents here...
</div>

Sample DF:

In [79]: df = pd.DataFrame(np.random.randint(5, 15, (10, 3)), columns=list('abc'))

In [80]: df
Out[80]:
    a   b   c
0   6  11  11
1  14   7   8
2  13   5  11
3  13   7  11
4  13   5   9
5   5  11   9
6   9   8   6
7   5  11  10
8   8  10  14
9   7  14  13

present only those rows where b > 10

In [81]: df[df.b > 10]
Out[81]:
   a   b   c
0  6  11  11
5  5  11   9
7  5  11  10
9  7  14  13

Minimums (for all columns) for the rows satisfying b > 10 condition

In [82]: df[df.b > 10].min()
Out[82]:
a     5
b    11
c     9
dtype: int32

Minimum (for the b column) for the rows satisfying b > 10 condition

In [84]: df.loc[df.b > 10, 'b'].min()
Out[84]: 11

UPDATE: starting from Pandas 0.20.1 the .ix indexer is deprecated, in favor of the more strict .iloc and .loc indexers.

ProcessBuilder is the Java 5/6 way to run external processes.

With dplyr package, Use

 nrow(filter(mydata, sCode == "CA")),

All the solutions provided here gave me same error as multi-sam but that one worked.

Here is the same problem.

You need to set table-layout:fixed and a suitable width on the table element, as well as overflow:hidden and white-space: nowrap on the table cells.

Examples

Fixed width columns

The width of the table has to be the same (or smaller) than the fixed width cell(s).

With one fixed width column:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 100px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

With multiple fixed width columns:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
  max-width: 200px;
}
td {
  background: #F00;
  padding: 20px;
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
  border: solid 1px #000;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

Fixed and fluid width columns

A width for the table must be set, but any extra width is simply taken by the fluid cell(s).

With multiple columns, fixed width and fluid width:

* {
  box-sizing: border-box;
}
table {
  table-layout: fixed;
  border-collapse: collapse;
  width: 100%;
}
td {
  background: #F00;
  padding: 20px;
  border: solid 1px #000;
}
tr td:first-child {
  overflow: hidden;
  white-space: nowrap;
  width: 100px;
}

<table>
  <tbody>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
    <tr>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
      <td>
        This_is_a_terrible_example_of_thinking_outside_the_box.
      </td>
    </tr>
  </tbody>
</table>

For my case, I was trying to execute procedure code in MySQL, and due to some issue with server in which Server can't figure out where to end the statement I was getting Error Code 1064. So I wrapped the procedure with custom DELIMITER and it worked fine.

For example, Before it was:

DROP PROCEDURE IF EXISTS getStats;
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;

After putting DELIMITER it was like this:

DROP PROCEDURE IF EXISTS getStats;
DELIMITER $$
CREATE PROCEDURE `getStats` (param_id INT, param_offset INT, param_startDate datetime, param_endDate datetime)
BEGIN
    /*Procedure Code Here*/
END;
$$
DELIMITER ;

The problem is that C++ is a statically-typed language, meaning that if something is declared as a string, it's a string, and if something is declared as a double, it's a double. Unlike other languages like JavaScript or PHP, there is no way to automatically convert from a string to a numeric value because the conversion might not be well-defined. For example, if you try converting the string "Hi there!" to a double, there's no meaningful conversion. Sure, you could just set the double to 0.0 or NaN, but this would almost certainly be masking the fact that there's a problem in the code.

To fix this, don't buffer the file contents into a string. Instead, just read directly into the double:

double lol;
openfile >> lol;

This reads the value directly as a real number, and if an error occurs will cause the stream's .fail() method to return true. For example:

double lol;
openfile >> lol;

if (openfile.fail()) {
    cout << "Couldn't read a double from the file." << endl;
}

I encountered the same problem even I set "UseDefaultCredentials" to false. Later I found that the root cause is that I turned on "2-step Verification" in my account. After I turned it off, the problem is gone.

Before The execution of following code, I assume you have created a database and a table (with columns Name (varchar), Age(INT) and Address(varchar)) inside that database. Also please update your SQL Server name , UserID, password, DBname and table name in the code below.

In the code. I have used VBScript and embedded it in HTML. Try it out!

<!DOCTYPE html>
<html>
<head>
<script type="text/vbscript">
<!--    

Sub Submit_onclick()
Dim Connection
Dim ConnString
Dim Recordset

Set connection=CreateObject("ADODB.Connection")
Set Recordset=CreateObject("ADODB.Recordset")
ConnString="DRIVER={SQL Server};SERVER=*YourSQLserverNameHere*;UID=*YourUserIdHere*;PWD=*YourpasswordHere*;DATABASE=*YourDBNameHere*"
Connection.Open ConnString

dim form1
Set form1 = document.Register

Name1 = form1.Name.value
Age1 = form1.Age.Value
Add1 = form1.address.value

connection.execute("INSERT INTO [*YourTableName*] VALUES ('"&Name1 &"'," &Age1 &",'"&Add1 &"')")

End Sub

//-->
</script>
</head>
<body>

<h2>Please Fill details</h2><br>
<p>
<form name="Register">
<pre>
<font face="Times New Roman" size="3">Please enter the log in credentials:<br>

<input type="button" id ="Submit" value="submit" /><font></form> 
</p>
</pre>
</body>
</html>

why not simply

new Date (timestamp);

A date is a date, the formatting of it is a different matter.

You have not appended your li as a child to your ul element

Try this

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Four"));
  ul.appendChild(li);
}

If you need to set the id , you can do so by

li.setAttribute("id", "element4");

Which turns the function into

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Four"));
  li.setAttribute("id", "element4"); // added line
  ul.appendChild(li);
  alert(li.id);
}

you may try the TO_CHAR function to convert the result

e.g.

SELECT TO_CHAR(92, '99.99') AS RES FROM DUAL

SELECT TO_CHAR(92.258, '99.99') AS RES FROM DUAL

Hope it helps

Generally to count distinct values in single column, you can use Series.value_counts:

df.domain.value_counts()

#'vk.com'          5
#'twitter.com'     2
#'facebook.com'    1
#'google.com'      1
#Name: domain, dtype: int64

To see how many unique values in a column, use Series.nunique:

df.domain.nunique()
# 4

To get all these distinct values, you can use unique or drop_duplicates, the slight difference between the two functions is that unique return a numpy.array while drop_duplicates returns a pandas.Series:

df.domain.unique()
# array(["'vk.com'", "'twitter.com'", "'facebook.com'", "'google.com'"], dtype=object)

df.domain.drop_duplicates()
#0          'vk.com'
#2     'twitter.com'
#4    'facebook.com'
#6      'google.com'
#Name: domain, dtype: object

As for this specific problem, since you'd like to count distinct value with respect to another variable, besides groupby method provided by other answers here, you can also simply drop duplicates firstly and then do value_counts():

import pandas as pd
df.drop_duplicates().domain.value_counts()

# 'vk.com'          3
# 'twitter.com'     2
# 'facebook.com'    1
# 'google.com'      1
# Name: domain, dtype: int64

With this approach, there is no need to import any library.

DateTime now = DateTime.now();

String convertedDateTime = "${now.year.toString()}-${now.month.toString().padLeft(2,'0')}-${now.day.toString().padLeft(2,'0')} ${now.hour.toString()}-${now.minute.toString()}";

Output

2020-12-05 14:57

Add this permission in Manifest,
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

File folder = new File(Environment.getExternalStorageDirectory() + 
                             File.separator + "TollCulator");
boolean success = true;
if (!folder.exists()) {
    success = folder.mkdirs();
}
if (success) {
    // Do something on success
} else {
    // Do something else on failure 
}

when u run the application go too DDMS->File Explorer->mnt folder->sdcard folder->toll-creation folder

Supose you have the following scenario:

* 1bd2200 (HEAD, master) another commit
* d258546 bad commit
* 0f1efa9 3rd commit
* bd8aa13 2nd commit
* 34c4f95 1st commit

Where you want to remove d258546 i.e. "bad commit".

You shall try an interactive rebase to remove it: git rebase -i 34c4f95

then your default editor will pop with something like this:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick d258546 bad commit
 pick 1bd2200 another commit

 # Rebase 34c4f95..1bd2200 onto 34c4f95
 #
 # Commands:
 #  p, pick = use commit
 #  r, reword = use commit, but edit the commit message
 #  e, edit = use commit, but stop for amending
 #  s, squash = use commit, but meld into previous commit
 #  f, fixup = like "squash", but discard this commit's log message
 #  x, exec = run command (the rest of the line) using shell
 #
 # These lines can be re-ordered; they are executed from top to bottom.
 #
 # If you remove a line here THAT COMMIT WILL BE LOST.
 #
 # However, if you remove everything, the rebase will be aborted.
 #
 # Note that empty commits are commented out

just remove the line with the commit you want to strip and save+exit the editor:

 pick bd8aa13 2nd commit
 pick 0f1efa9 3rd commit
 pick 1bd2200 another commit
 ...

git will proceed to remove this commit from your history leaving something like this (mind the hash change in the commits descendant from the removed commit):

 * 34fa994 (HEAD, master) another commit
 * 0f1efa9 3rd commit
 * bd8aa13 2nd commit
 * 34c4f95 1st commit

Now, since I suppose that you already pushed the bad commit to gitlab, you'll need to repush your graph to the repository (but with the -f option to prevent it from being rejected due to a non fastforwardeable history i.e. git push -f <your remote> <your branch>)

Please be extra careful and make sure that none coworker is already using the history containing the "bad commit" in their branches.

Alternative option:

Instead of rewrite the history, you may simply create a new commit which negates the changes introduced by your bad commit, to do this just type git revert <your bad commit hash>. This option is maybe not as clean, but is far more safe (in case you are not fully aware of what are you doing with an interactive rebase).

  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

innerHTML explanation with example:

The innerHTML manipulates the HTML content of an element(get or set). In the example below if you click on the Change Content link it's value will be updated by using innerHTML property of anchor link Change Content

Example:

<a id="example" onclick='testFunction()'>Change Content</a>_x000D_
_x000D_
<script>_x000D_
  function testFunction(){_x000D_
    // change the content using innerHTML_x000D_
    document.getElementById("example").innerHTML = "This is dummy content";_x000D_
_x000D_
    // get the content using innerHTML_x000D_
    alert(document.getElementById("example").innerHTML)_x000D_
_x000D_
  }_x000D_
</script>_x000D_
    

the behaviour of fixed elements (and absolute elements) as defined in CSS Spec:

They behave as they are detached from document, and placed in the nearest fixed/absolute positioned parent. (not a word by word quote)

This makes zindex calculation a bit complicated, I solved my problem (the same situation) by dynamically creating a container in body element and moving all such elements (which are class-ed as "my-fixed-ones" inside that body-level element)

What worked for me after following all your workarounds was to call the API:

 <script async defer src="https://maps.googleapis.com/maps/api/js?key=you_API_KEY&callback=initMap&libraries=places"
            type="text/javascript"></script>

before my : <div id="map"></div>

I have a solution for this. First thing that add is already having a string value as input() function by default takes the input as string. Second thing that you can use append method to append value of add variable in your list.

Please do check my code I have done some modification : - {1} You can enter command in capital or small or mix {2} If user entered wrong command then your program will ask to input command again

inventory = ["sword","potion","armour","bow"] print(inventory) print("\ncommands : use (remove item) and pickup (add item)") selection=input("choose a command [use/pickup] : ") while True: if selection.lower()=="use": print(inventory) remove_item=input("What do you want to use? ") inventory.remove(remove_item) print(inventory) break

 elif selection.lower()=="pickup":
      print(inventory)
      add_item=input("What do you want to pickup? ")
      inventory.append(add_item)
      print(inventory)
      break
 
 else:
      print("Invalid Command. Please check your input")
      selection=input("Once again choose a command [use/pickup] : ")

Set the datasource property to an empty string then call the Clear method.

This indicates you are trying to put something too big into a column. For example, you have a VARCHAR2(10) column and you are putting in 11 characters. Same thing with number.

This is happening at line 176 of package UMAIN. You would need to go and have a look at that to see what it is up to. Hopefully you can look it up in your source control (or from user_source). Later versions of Oracle report this error better, telling you which column and what value.

Quite simple, with a * wildcard.

cp -r Folder1/* Folder2/

But according to your example recursion is not needed so the following will suffice:

cp Folder1/* Folder2/

EDIT:

Or skip the mkdir Folder2 part and just run:

cp -r Folder1 Folder2

Easiest way I know of is to use "child_process" package which comes packaged with node.

Then you can do something like:

const spawn = require("child_process").spawn;
const pythonProcess = spawn('python',["path/to/script.py", arg1, arg2, ...]);

Then all you have to do is make sure that you import sys in your python script, and then you can access arg1 using sys.argv[1], arg2 using sys.argv[2], and so on.

To send data back to node just do the following in the python script:

print(dataToSendBack)
sys.stdout.flush()

And then node can listen for data using:

pythonProcess.stdout.on('data', (data) => {
    // Do something with the data returned from python script
});

Since this allows multiple arguments to be passed to a script using spawn, you can restructure a python script so that one of the arguments decides which function to call, and the other argument gets passed to that function, etc.

Hope this was clear. Let me know if something needs clarification.

Predicate<Client> hasSameNameAsOneUser = 
    c -> users.stream().anyMatch(u -> u.getName().equals(c.getName()));

return clients.stream()
              .filter(hasSameNameAsOneUser)
              .collect(Collectors.toList());

But this is quite inefficient, because it's O(m * n). You'd better create a Set of acceptable names:

Set<String> acceptableNames = 
    users.stream()
         .map(User::getName)
         .collect(Collectors.toSet());

return clients.stream()
              .filter(c -> acceptableNames.contains(c.getName()))
              .collect(Collectors.toList());

Also note that it's not strictly equivalent to the code you have (if it compiled), which adds the same client twice to the list if several users have the same name as the client.

1. Android Sqlite Database

2. Tutorial 1

Database Helper Class:

A helper class to manage database creation and version management.

You create a subclass implementing onCreate(SQLiteDatabase), onUpgrade(SQLiteDatabase, int, int) and optionally onOpen(SQLiteDatabase), and this class takes care of opening the database if it exists, creating it if it does not, and upgrading it as necessary. Transactions are used to make sure the database is always in a sensible state.

This class makes it easy for ContentProvider implementations to defer opening and upgrading the database until first use, to avoid blocking application startup with long-running database upgrades.

Something to be aware of, the $_SESSION variables are still set in the same page after calling session_destroy() where as this is not the case when using unset($_SESSION) or $_SESSION = array(). Also, unset($_SESSION) blows away the $_SESSION superglobal so only do this when you're destroying a session.

With all that said, it's best to do like the PHP docs has it in the first example for session_destroy().

import sys
for a in sys.path:
    a.replace('\\\\','\\')
    print(a)

It will give all the paths ready for place in the Windows.

You don't import scripts in Python you import modules. Some python modules are also scripts that you can run directly (they do some useful work at a module-level).

In general it is preferable to use absolute imports rather than relative imports.

toplevel_package/
+-- __init__.py
+-- moduleA.py
+-- subpackage
    +-- __init__.py
    +-- moduleB.py

In moduleB:

from toplevel_package import moduleA

If you'd like to run moduleB.py as a script then make sure that parent directory for toplevel_package is in your sys.path.

@eric answer did the trick for me, you need to accept terms in the command you are setting i.e

"Cookie: oraclelicense=accept-securebackup-cookie"

so your final command looks thus

wget -c --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz

You can decide to update the version by changing 8u131 to 8uXXX. so long it is available in the repo.

this would be good log4j error/exception logging - readable by splunk/other logging/monitoring s/w. everything is form of key-value pair. log4j would get the stack trace from Exception obj e

Change the number of @grid-columns. Then use -offset. Changing the number of columns will allow you to control the amount of space between columns. E.g.

variables.less (approx line 294).

@grid-columns:              20;

The answer at https://stackoverflow.com/a/35904801/2373449 helped me

As I have found and wrote in another topic - this applies to angular < 7 (not sure how it is in 7+)

Just for the future

we need to observe that [(ngModel)]="hero.name" is just a short-cut that can be de-sugared to: [ngModel]="hero.name" (ngModelChange)="hero.name = $event".

So if we de-sugar code we would end up with:

<select (ngModelChange)="onModelChange()" [ngModel]="hero.name" (ngModelChange)="hero.name = $event">

or

<[ngModel]="hero.name" (ngModelChange)="hero.name = $event" select (ngModelChange)="onModelChange()">

If you inspect the above code you will notice that we end up with 2 ngModelChange events and those need to be executed in some order.

Summing up: If you place ngModelChange before ngModel, you get the $event as the new value, but your model object still holds previous value. If you place it after ngModel, the model will already have the new value.

SOURCE

As of Git v2.23.0 (August 2019), git switch is preferred over git checkout when you’re simply switching branches/tags. I’m guessing they did this since git checkout had two functions: for switching branches and for restoring files. So in v2.23.0, they added two new commands, git switch, and git restore, to separate those concerns. I would predict at some point in the future, git checkout will be deprecated.

To switch to a normal branch, use git switch <branch-name>. To switch to a commit-like object, including single commits and tags, use git switch --detach <commitish>, where <commitish> is the tag name or commit number.

The --detach option forces you to recognize that you’re in a mode of “inspection and discardable experiments”. To create a new branch from the commitish you’re switching to, use git switch -c <new-branch> <start-point>.

EXE:

1. It's a executable file
2. When loading an executable, no export is called, but only the module entry point.
3. When a system launches new executable, a new process is created
4. The entry thread is called in context of main thread of that process.

DLL:

1. It's a Dynamic Link Library
2. There are multiple exported symbols.
3. The system loads a DLL into the context of an existing process.

I found this working fine and useful to create a List from a Set.

ArrayList < String > L1 = new ArrayList < String > ();
L1.addAll(ActualMap.keySet());
for (String x: L1) {
    System.out.println(x.toString());
}

Short version Plunker:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
      <input #myInput type="file" placeholder="File Name" name="filename">
      <button (click)="myInput.value = ''">Reset</button>
  `
})
export class AppComponent {


}

And i think more common case is to not using button but do reset automatically. Angular Template statements support chaining expressions so Plunker:

import { Component } from '@angular/core';

@Component({
  selector: 'my-app',
  template: `
      <input #myInput type="file" (change)="onChange(myInput.value, $event); myInput.value = ''" placeholder="File Name" name="filename">
  `
})
export class AppComponent {

  onChange(files, event) {
    alert( files );
    alert( event.target.files[0].name );
  }

}

1. In Android Studio switch to Project perspective (not Android perspective).

2. Make sure that your project follows the gradle plugin's default structure (i.e. project_dir/app/src/main/java...)

3. Delete all build folders and subfolders that you see.

4. In the toolbar click Build -> Clean Project, then Build -> Rebuild Project.

5. Try to run the project.

Variables, in contrast with simple properties, have attribute [[Configurable]], meaning impossibility to remove a variable via the delete operator. However there is one execution context on which this rule does not affect. It is the eval context: there [[Configurable]] attribute is not set for variables.

You could explicitly set where you want to tick marks with plt.xticks:

plt.xticks(np.arange(min(x), max(x)+1, 1.0))

For example,

import numpy as np
import matplotlib.pyplot as plt

x = [0,5,9,10,15]
y = [0,1,2,3,4]
plt.plot(x,y)
plt.xticks(np.arange(min(x), max(x)+1, 1.0))
plt.show()

(np.arange was used rather than Python's range function just in case min(x) and max(x) are floats instead of ints.)

The plt.plot (or ax.plot) function will automatically set default x and y limits. If you wish to keep those limits, and just change the stepsize of the tick marks, then you could use ax.get_xlim() to discover what limits Matplotlib has already set.

start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, stepsize))

The default tick formatter should do a decent job rounding the tick values to a sensible number of significant digits. However, if you wish to have more control over the format, you can define your own formatter. For example,

ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))

Here's a runnable example:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.ticker as ticker

x = [0,5,9,10,15]
y = [0,1,2,3,4]
fig, ax = plt.subplots()
ax.plot(x,y)
start, end = ax.get_xlim()
ax.xaxis.set_ticks(np.arange(start, end, 0.712123))
ax.xaxis.set_major_formatter(ticker.FormatStrFormatter('%0.1f'))
plt.show()

To:

Another answer, because jQuery.transit is not compatible with jQuery.easing. This solution comes as an jQuery extension. Is more generic, rotation is a specific case:

$.fn.extend({
    animateStep: function(options) {
        return this.each(function() {
            var elementOptions = $.extend({}, options, {step: options.step.bind($(this))});
            $({x: options.from}).animate({x: options.to}, elementOptions);
        });
    },
    rotate: function(value) {
        return this.css("transform", "rotate(" + value + "deg)");
    }
});

The usage is as simple as:

$(element).animateStep({from: 0, to: 90, step: $.fn.rotate});

The data-reactid attribute is a custom attribute used so that React can uniquely identify its components within the DOM.

This is important because React applications can be rendered at the server as well as the client. Internally React builds up a representation of references to the DOM nodes that make up your application (simplified version is below).

{
  id: '.1oqi7occu80',
  node: DivRef,
  children: [
    {
      id: '.1oqi7occu80.0',
      node: SpanRef,
      children: [
        {
          id: '.1oqi7occu80.0.0',
          node: InputRef,
          children: []
        }
      ]
    }
  ]
}

There's no way to share the actual object references between the server and the client and sending a serialized version of the entire component tree is potentially expensive. When the application is rendered at the server and React is loaded at the client, the only data it has are the data-reactid attributes.

<div data-reactid='.loqi70ccu80'>
  <span data-reactid='.loqi70ccu80.0'>
    <input data-reactid='.loqi70ccu80.0' />
  </span>
</div>

It needs to be able to convert that back into the data structure above. The way it does that is with the unique data-reactid attributes. This is called inflating the component tree.

You might also notice that if React renders at the client-side, it uses the data-reactid attribute, even though it doesn't need to lose its references. In some browsers, it inserts your application into the DOM using .innerHTML then it inflates the component tree straight away, as a performance boost.

The other interesting difference is that client-side rendered React ids will have an incremental integer format (like .0.1.4.3), whereas server-rendered ones will be prefixed with a random string (such as .loqi70ccu80.1.4.3). This is because the application might be rendered across multiple servers and it's important that there are no collisions. At the client-side, there is only one rendering process, which means counters can be used to ensure unique ids.

React 15 uses document.createElement instead, so client rendered markup won't include these attributes anymore.

Try adding LD_LIBRARY_PATH, which indicates search paths, to your ~/.bashrc file

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path_to_your_library

It works!

Context means component (or application) in various time-period. If I do eat so much food between 1 to 2 pm then my context of that time is used to access all methods (or resources) that I use during that time. Content is a component (application) for a particular time. The Context of components of the application keeps changing based on the underlying lifecycle of the components or application. For instance, inside the onCreate() of an Activity,

getBaseContext() -- gives the context of the Activity that is set (created) by the constructor of activity. getApplicationContext() -- gives the Context setup (created) during the creation of application.

Note: <application> holds all Android Components.

<application>
    <activity> .. </activity> 

    <service>  .. </service>

    <receiver> .. </receiver>

    <provider> .. </provider>
</application> 

It means, when you call getApplicationContext() from inside whatever component, you are calling the common context of the whole application.

Context keeps being modified by the system based on the lifecycle of components.

Or equivalently (see comments below):

if (! ($(this).parent().next().is('ul'))){

Introduction

Object-Relational Mapping (ORM) is a technique that lets you query and manipulate data from a database using an object-oriented paradigm. When talking about ORM, most people are referring to a library that implements the Object-Relational Mapping technique, hence the phrase "an ORM".

An ORM library is a completely ordinary library written in your language of choice that encapsulates the code needed to manipulate the data, so you don't use SQL anymore; you interact directly with an object in the same language you're using.

For example, here is a completely imaginary case with a pseudo language:

You have a book class, you want to retrieve all the books of which the author is "Linus". Manually, you would do something like that:

book_list = new List();
sql = "SELECT book FROM library WHERE author = 'Linus'";
data = query(sql); // I over simplify ...
while (row = data.next())
{
     book = new Book();
     book.setAuthor(row.get('author');
     book_list.add(book);
}

With an ORM library, it would look like this:

book_list = BookTable.query(author="Linus");

The mechanical part is taken care of automatically via the ORM library.

Pros and Cons

Using ORM saves a lot of time because:

• DRY: You write your data model in only one place, and it's easier to update, maintain, and reuse the code.
• A lot of stuff is done automatically, from database handling to I18N.
• It forces you to write MVC code, which, in the end, makes your code a little cleaner.
• You don't have to write poorly-formed SQL (most Web programmers really suck at it, because SQL is treated like a "sub" language, when in reality it's a very powerful and complex one).
• Sanitizing; using prepared statements or transactions are as easy as calling a method.

Using an ORM library is more flexible because:

• It fits in your natural way of coding (it's your language!).
• It abstracts the DB system, so you can change it whenever you want.
• The model is weakly bound to the rest of the application, so you can change it or use it anywhere else.
• It lets you use OOP goodness like data inheritance without a headache.

But ORM can be a pain:

• You have to learn it, and ORM libraries are not lightweight tools;
• You have to set it up. Same problem.
• Performance is OK for usual queries, but a SQL master will always do better with his own SQL for big projects.
• It abstracts the DB. While it's OK if you know what's happening behind the scene, it's a trap for new programmers that can write very greedy statements, like a heavy hit in a for loop.

How to learn about ORM?

Well, use one. Whichever ORM library you choose, they all use the same principles. There are a lot of ORM libraries around here:

• Java: Hibernate.
• PHP: Propel or Doctrine (I prefer the last one).
• Python: the Django ORM or SQLAlchemy (My favorite ORM library ever).
• C#: NHibernate or Entity Framework

If you want to try an ORM library in Web programming, you'd be better off using an entire framework stack like:

• Symfony (PHP, using Propel or Doctrine).
• Django (Python, using a internal ORM).

Do not try to write your own ORM, unless you are trying to learn something. This is a gigantic piece of work, and the old ones took a lot of time and work before they became reliable.

The problem with your code is that when you do

 list[] == "e"

you're asking if the array object (not the contents) is equal to the string "e", which is clearly not the case.

You'll want to iterate over the contents in order to do the check you want:

 for(String element : list) {
      if (element.equals("e")) {
           // do something here
      }
 }

The macros defined in <inttypes.h> are the most correct way to print values of types uint32_t, uint16_t, and so forth -- but they're not the only way.

Personally, I find those macros difficult to remember and awkward to use. (Given the syntax of a printf format string, that's probably unavoidable; I'm not claiming I could have come up with a better system.)

An alternative is to cast the values to a predefined type and use the format for that type.

Types int and unsigned int are guaranteed by the language to be at least 16 bits wide, and therefore to be able to hold any converted value of type int16_t or uint16_t, respectively. Similarly, long and unsigned long are at least 32 bits wide, and long long and unsigned long long are at least 64 bits wide.

For example, I might write your program like this (with a few additional tweaks):

#include <stdio.h>
#include <stdint.h>
#include <netinet/in.h>  

int main(void)
{
    uint32_t a=12, a1;
    uint16_t b=1, b1;
    a1 = htonl(a);
    printf("%lu---------%lu\n", (unsigned long)a, (unsigned long)a1);
    b1 = htons(b);
    printf("%u-----%u\n", (unsigned)b, (unsigned)b1);
    return 0;
}

One advantage of this approach is that it can work even with pre-C99 implementations that don't support <inttypes.h>. Such an implementation most likely wouldn't have <stdint.h> either, but the technique is useful for other integer types.

I needed some extra fields for it to work properly, as chrome actually fills many fields. And I also needed to hide the fields in a more fancy way than display:none for it to actually work.

<style>.stylish { position:absolute; top:-2000px; }</style>

This one automatically excludes the trailing comma, unlike most of the other answers.

(If the ModuleValue column isn't already a string type then you might need to cast it to a VARCHAR.)

If you dont want to format a separate column with you normal dates pasted to it -- do the following -- add a column to the extreme left of your data and reverve your date ie if the date you had already entered was for example 11.5.16 enter int he new lefthand column 160511 ( notice that there are numbers only and no full stops . When you now sort there will be no mix ups as you have encountered.i have used this method for over 30 years and it never lets me down. And as you have placed the date by year, month and day you neednt include that column if you want or need tu print out your complete list.

I would start by adding clearfix class to the <div> with panel-heading class. Then, add both panel-title and pull-left to the H4 tag. Then, add padding-top, as necessary.

Here's the complete code:

<div class="panel panel-default">
    <div class="panel-heading clearfix">
      <h4 class="panel-title pull-left" style="padding-top: 7.5px;">Panel header</h4>
      <div class="btn-group pull-right">
        <a href="#" class="btn btn-default btn-sm">## Lock</a>
        <a href="#" class="btn btn-default btn-sm">## Delete</a>
        <a href="#" class="btn btn-default btn-sm">## Move</a>
      </div>
    </div>
    ...
</div>

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

You could also do this which would include all JARs in the local repository. This way you wouldn't have to specify it every time.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

This is Linq

var mergedList = list1.Union(list2).ToList();

This is Normaly (AddRange)

var mergedList=new List<Person>();
mergeList.AddRange(list1);
mergeList.AddRange(list2);

This is Normaly (Foreach)

var mergedList=new List<Person>();

foreach(var item in list1)
{
    mergedList.Add(item);
}
foreach(var item in list2)
{
     mergedList.Add(item);
}

This is Normaly (Foreach-Dublice)

var mergedList=new List<Person>();

foreach(var item in list1)
{
    mergedList.Add(item);
}
foreach(var item in list2)
{
   if(!mergedList.Contains(item))
   {
     mergedList.Add(item);
   }
}

I would use

WHERE columnName LIKE '%[%]%'

SQL Server stores string summary statistics for use in estimating the number of rows that will match a LIKE clause. The cardinality estimates can be better and lead to a more appropriate plan when the square bracket syntax is used.

The response to this Connect Item states

We do not have support for precise cardinality estimation in the presence of user defined escape characters. So we probably get a poor estimate and a poor plan. We'll consider addressing this issue in a future release.

An example

CREATE TABLE T
(
X VARCHAR(50),
Y CHAR(2000) NULL
)

CREATE NONCLUSTERED INDEX IX ON T(X)

INSERT INTO T (X)
SELECT TOP (5) '10% off'
FROM master..spt_values
UNION ALL
SELECT  TOP (100000)  'blah'
FROM master..spt_values v1,  master..spt_values v2


SET STATISTICS IO ON;
SELECT *
FROM T 
WHERE X LIKE '%[%]%'

SELECT *
FROM T
WHERE X LIKE '%\%%' ESCAPE '\'

Shows 457 logical reads for the first query and 33,335 for the second.

According to the documentation Checks the existence of files in the specified order and uses the first found file for request processing; the processing is performed in the current context. The path to a file is constructed from the file parameter according to the root and alias directives. It is possible to check directory’s existence by specifying a slash at the end of a name, e.g. “$uri/”. If none of the files were found, an internal redirect to the uri specified in the last parameter is made. Important

an internal redirect to the uri specified in the last parameter is made.

So in last parameter you should add your page or code if first two parameters returns false.

location / {
  try_files $uri $uri/index.html index.html;
}

Scala inherits most of Java's arithmetic operators. This includes bitwise-or | (single pipe character), bitwise-and &, bitwise-exclusive-or ^, as well as logical (boolean) or || (two pipe characters) and logical-and &&. Interestingly, you can use the single character operators on boolean, so the java'ish logical operators are totally redundant:

true && true   // valid
true & true    // valid as well

3 & 4          // bitwise-and (011 & 100 yields 000)
3 && 4         // not valid

As pointed out in another post, calls ending in an equals sign =, are resolved (if a method with that name does not exist!) by a reassignment:

var x = 3
x += 1         // `+=` is not a method in `int`, Scala makes it `x = x + 1`

This 'double-check' makes it possible, to easily exchange a mutable for an immutable collection:

val m = collection.mutable.Set("Hallo")   // `m` a val, but holds mutable coll
var i = collection.immutable.Set("Hallo") // `i` is a var, but holds immutable coll

m += "Welt" // destructive call m.+=("Welt")
i += "Welt" // re-assignment i = i + "Welt" (creates a new immutable Set)

What I have observed is that when you switch wifi connections when the android emulator is running. It isn't able to connect to new wifi.

A simple solution is to restart the android emulator.

A good summary of LLVM is this:

At the frontend you have Perl, and many other high level languages. At the backend, you have the natives code that run directly on the machine.

At the centre is your intermediate code representation. If every high level language can be represented in this LLVM IR format, then analysis tools based on this IR can be easily reused - that is the basic rationale.

Come on guys, there is no need to loop, just use simple math to solve this equation system:

a*b = i;

a+b = j;

a = j/b;

a = i-b;

j/b = i-b; so:

b + j/b + i = 0

b^2 + i*b + j = 0

From here, its a quadratic equation, and it's trivial to find b (just implement the quadratic equation formula) and from there get the value for a.

EDIT:

There you go:

function finder($add,$product)
{

 $inside_root = $add*$add - 4*$product;

 if($inside_root >=0)
 {

     $b = ($add + sqrt($inside_root))/2;
     $a = $add - $b;

     echo "$a+$b = $add and $a*$b=$product\n";

 }else
 {
   echo "No real solution\n";
 }
}

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

My problem was actually a problem of bad planning with the JSON object rather than an actual logic issue. What I ended up doing was organize the object as follows, per a suggestion from user2736012.

{
"dialog":
{
    "trunks":[
    {
        "trunk_id" : "1",
        "message": "This is just a JSON Test"
    },
    {
        "trunk_id" : "2",
        "message": "This is a test of a bit longer text. Hopefully this will at the very least create 3 lines and trigger us to go on to another box. So we can test multi-box functionality, too."
    }
    ]
}
}

At that point, I was able to do a fairly simple for loop based on the total number of objects.

var totalMessages = Object.keys(messages.dialog.trunks).length;

    for ( var i = 0; i < totalMessages; i++)
    {
        console.log("ID: " + messages.dialog.trunks[i].trunk_id + " Message " + messages.dialog.trunks[i].message);
    }

My method for getting totalMessages is not supported in all browsers, though. For my project, it actually doesn't matter, but beware of that if you choose to use something similar to this.

Floating point numbers are represented, at the hardware level, as fractions of binary numbers (base 2). For example, the decimal fraction:

0.125

has the value 1/10 + 2/100 + 5/1000 and, in the same way, the binary fraction:

0.001

has the value 0/2 + 0/4 + 1/8. These two fractions have the same value, the only difference is that the first is a decimal fraction, the second is a binary fraction.

Unfortunately, most decimal fractions cannot have exact representation in binary fractions. Therefore, in general, the floating point numbers you give are only approximated to binary fractions to be stored in the machine.

The problem is easier to approach in base 10. Take for example, the fraction 1/3. You can approximate it to a decimal fraction:

0.3

or better,

0.33

or better,

0.333

etc. No matter how many decimal places you write, the result is never exactly 1/3, but it is an estimate that always comes closer.

Likewise, no matter how many base 2 decimal places you use, the decimal value 0.1 cannot be represented exactly as a binary fraction. In base 2, 1/10 is the following periodic number:

0.0001100110011001100110011001100110011001100110011 ...

Stop at any finite amount of bits, and you'll get an approximation.

For Python, on a typical machine, 53 bits are used for the precision of a float, so the value stored when you enter the decimal 0.1 is the binary fraction.

0.00011001100110011001100110011001100110011001100110011010

which is close, but not exactly equal, to 1/10.

It's easy to forget that the stored value is an approximation of the original decimal fraction, due to the way floats are displayed in the interpreter. Python only displays a decimal approximation of the value stored in binary. If Python were to output the true decimal value of the binary approximation stored for 0.1, it would output:

>>> 0.1
0.1000000000000000055511151231257827021181583404541015625

This is a lot more decimal places than most people would expect, so Python displays a rounded value to improve readability:

>>> 0.1
0.1

It is important to understand that in reality this is an illusion: the stored value is not exactly 1/10, it is simply on the display that the stored value is rounded. This becomes evident as soon as you perform arithmetic operations with these values:

>>> 0.1 + 0.2
0.30000000000000004

This behavior is inherent to the very nature of the machine's floating-point representation: it is not a bug in Python, nor is it a bug in your code. You can observe the same type of behavior in all other languages ??that use hardware support for calculating floating point numbers (although some languages ??do not make the difference visible by default, or not in all display modes).

Another surprise is inherent in this one. For example, if you try to round the value 2.675 to two decimal places, you will get

>>> round (2.675, 2)
2.67

The documentation for the round() primitive indicates that it rounds to the nearest value away from zero. Since the decimal fraction is exactly halfway between 2.67 and 2.68, you should expect to get (a binary approximation of) 2.68. This is not the case, however, because when the decimal fraction 2.675 is converted to a float, it is stored by an approximation whose exact value is :

2.67499999999999982236431605997495353221893310546875

Since the approximation is slightly closer to 2.67 than 2.68, the rounding is down.

If you are in a situation where rounding decimal numbers halfway down matters, you should use the decimal module. By the way, the decimal module also provides a convenient way to "see" the exact value stored for any float.

>>> from decimal import Decimal
>>> Decimal (2.675)
>>> Decimal ('2.67499999999999982236431605997495353221893310546875')

Another consequence of the fact that 0.1 is not exactly stored in 1/10 is that the sum of ten values ??of 0.1 does not give 1.0 either:

>>> sum = 0.0
>>> for i in range (10):
... sum + = 0.1
...>>> sum
0.9999999999999999

The arithmetic of binary floating point numbers holds many such surprises. The problem with "0.1" is explained in detail below, in the section "Representation errors". See The Perils of Floating Point for a more complete list of such surprises.

It is true that there is no simple answer, however do not be overly suspicious of floating virtula numbers! Errors, in Python, in floating-point number operations are due to the underlying hardware, and on most machines are no more than 1 in 2 ** 53 per operation. This is more than necessary for most tasks, but you should keep in mind that these are not decimal operations, and every operation on floating point numbers may suffer from a new error.

Although pathological cases exist, for most common use cases you will get the expected result at the end by simply rounding up to the number of decimal places you want on the display. For fine control over how floats are displayed, see String Formatting Syntax for the formatting specifications of the str.format () method.

This part of the answer explains in detail the example of "0.1" and shows how you can perform an exact analysis of this type of case on your own. We assume that you are familiar with the binary representation of floating point numbers.The term Representation error means that most decimal fractions cannot be represented exactly in binary. This is the main reason why Python (or Perl, C, C ++, Java, Fortran, and many others) usually doesn't display the exact result in decimal:

>>> 0.1 + 0.2
0.30000000000000004

Why ? 1/10 and 2/10 are not representable exactly in binary fractions. However, all machines today (July 2010) follow the IEEE-754 standard for the arithmetic of floating point numbers. and most platforms use an "IEEE-754 double precision" to represent Python floats. Double precision IEEE-754 uses 53 bits of precision, so on reading the computer tries to convert 0.1 to the nearest fraction of the form J / 2 ** N with J an integer of exactly 53 bits. Rewrite :

1/10 ~ = J / (2 ** N)

in :

J ~ = 2 ** N / 10

remembering that J is exactly 53 bits (so> = 2 ** 52 but <2 ** 53), the best possible value for N is 56:

>>> 2 ** 52
4503599627370496
>>> 2 ** 53
9007199254740992
>>> 2 ** 56/10
7205759403792793

So 56 is the only possible value for N which leaves exactly 53 bits for J. The best possible value for J is therefore this quotient, rounded:

>>> q, r = divmod (2 ** 56, 10)
>>> r
6

Since the carry is greater than half of 10, the best approximation is obtained by rounding up:

>>> q + 1
7205759403792794

Therefore the best possible approximation for 1/10 in "IEEE-754 double precision" is this above 2 ** 56, that is:

7205759403792794/72057594037927936

Note that since the rounding was done upward, the result is actually slightly greater than 1/10; if we hadn't rounded up, the quotient would have been slightly less than 1/10. But in no case is it exactly 1/10!

So the computer never "sees" 1/10: what it sees is the exact fraction given above, the best approximation using the double precision floating point numbers from the "" IEEE-754 ":

>>>. 1 * 2 ** 56
7205759403792794.0

If we multiply this fraction by 10 ** 30, we can observe the values ??of its 30 decimal places of strong weight.

>>> 7205759403792794 * 10 ** 30 // 2 ** 56
100000000000000005551115123125L

meaning that the exact value stored in the computer is approximately equal to the decimal value 0.100000000000000005551115123125. In versions prior to Python 2.7 and Python 3.1, Python rounded these values ??to 17 significant decimal places, displaying “0.10000000000000001”. In current versions of Python, the displayed value is the value whose fraction is as short as possible while giving exactly the same representation when converted back to binary, simply displaying “0.1”.

Just use DateValue(Now) if you want the result to be of DateTime data type.

The "ARM EABI v7a System Image" must be available. Install it via the Android SDK manager:

Another hint (see here) - with

• Android SDK Tools rev 17 or higher
• Android 4.0.3 (API Level 15)
• using SDK rev 3 and System Image rev 2 (or higher)

you are able to turn on GPU emulation to get a faster emulator:

Note : As per you786 comment if you have previously created emulator then you need to recreate it, otherwise this will not work.

Alternative 1
Intel provides the "Intel hardware accelerated execution manager", which is a VM based emulator for executing X86 images and which is also served by the Android SDK Manager. See a tutorial for the Intel emulator here: HAXM Speeds Up the Android Emulator. Roman Nurik posts here that the Intel emulator with Android 4.3 is "blazing fast".

Alternative 2
In the comments of the post above you can find a reference to Genymotion which claims to be the "fastest Android emulator for app testing and presentation". Genymotion runs on VirtualBox. See also their site on Google+, this post from Cyril Mottier and this guide on reddit.

To avoid the race condition @GregPettit mentions, one can use:

($("element").data('bs.modal') || {})._isShown    // Bootstrap 4
($("element").data('bs.modal') || {}).isShown     // Bootstrap <= 3

as discussed in Twitter Bootstrap Modal - IsShown.

When the modal is not yet opened, .data('bs.modal') returns undefined, hence the || {} - which will make isShown the (falsy) value undefined. If you're into strictness one could do ($("element").data('bs.modal') || {isShown: false}).isShown

If you want to disable particular date(s) in jquery datepicker then here is the simple demo for you.

<script type="text/javascript">
    var arrDisabledDates = {};
    arrDisabledDates[new Date("08/28/2017")] = new Date("08/28/2017");
    arrDisabledDates[new Date("12/23/2017")] = new Date("12/23/2017");
    $(".datepicker").datepicker({
        dateFormat: "dd/mm/yy",
        beforeShowDay: function (date) {
            var day = date.getDay(),
                    bDisable = arrDisabledDates[date];
            if (bDisable)
                return [false, "", ""]
        }
    });
</script>

When using the header function, php does not trigger a close on the current session. You must use session_write_close to close the session and remove the file lock from the session file.

ob_start();
@session_start();

//some display stuff

$_SESSION['id'] = $id; //$id has a value
session_write_close();
header('location: test.php');

When you encounter exceptions like this, the most useful information is generally at the bottom of the stacktrace:

Caused by: java.lang.ClassNotFoundException: com.mysql.jdbc.Driver
  at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
  ...
  at org.apache.tomcat.jdbc.pool.PooledConnection.connectUsingDriver(PooledConnection.java:246)

The problem is that Tomcat can't find com.mysql.jdbc.Driver. This is usually caused by the JAR containing the MySQL driver not being where Tomcat expects to find it (namely in the webapps/<yourwebapp>/WEB-INF/lib directory).

Update: Visual Studio 2019 (Clean [bin] and [obj] before release). However I am not sure if [obj] needs to be deleted. Be aware there is nuget package configuration placed too. You can remove the second line if you think so.

This is a bit nasty, but:

from datetime import datetime, timedelta

now = datetime.now().time()
# Just use January the first, 2000
d1 = datetime(2000, 1, 1, now.hour, now.minute, now.second)
d2 = d1 + timedelta(hours=1, minutes=23)
print d2.time()

A collegue of me and I found out the following:

When we use the Microsoft .NET Oracle driver to connect to an oracle Database (System.Data.OracleClient.OracleConnection)

And we are trying to insert a string with a length between 2000 and 4000 characters into an CLOB or NCLOB field using a database-parameter

oraCommand.CommandText = "INSERT INTO MY_TABLE (NCLOB_COLUMN) VALUES (:PARAMETER1)";
// Add string-parameters with different lengths
// oraCommand.Parameters.Add("PARAMETER1", new string(' ', 1900)); // ok
oraCommand.Parameters.Add("PARAMETER1", new string(' ', 2500));  // Exception
//oraCommand.Parameters.Add("PARAMETER1", new string(' ', 4100)); // ok
oraCommand.ExecuteNonQuery();

• any string with a length under 2000 characters will not throw this exception
• any string with a length of more than 4000 characters will not throw this exception
• only strings with a length between 2000 and 4000 characters will throw this exception

We opened a ticket at microsoft for this bug many years ago, but it has still not been fixed.

You can do the following:

=Datevalue(text)+timevalue(text) .

Go into different types of date formats and choose:

dd-mm-yyyy mm:ss am/pm .

In Bootstrap 3.3.7 you can change the @input-border-focus value in the Forms section of the customizer:

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_
      });_x000D_
    });_x000D_
  };_x000D_
})(jQuery);_x000D_
_x000D_
$(document).ready(function() {_x000D_
  $('input.currency').currencyInput();_x000D_
});

.currency {_x000D_
  padding-left:12px;_x000D_
}_x000D_
_x000D_
.currency-symbol {_x000D_
  position:absolute;_x000D_
  padding: 2px 5px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="number" class="currency" min="0.01" max="2500.00" value="25.00" />

The simpliest solution is:

dialog.show(); //Only after .show() was called
dialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(neededColor);
dialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(neededColor);

Android 10 (Q) onwards wifi can not be enabled/disabled you need to open the setting intent,

// for android Q and above
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
            Intent panelIntent = new 
Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY);
            startActivityForResult(panelIntent, 0);
        } else {
            // for previous android version
            WifiManager wifiManager = (WifiManager) 
this.getApplicationContext().getSystemService(WIFI_SERVICE);
            wifiManager.setWifiEnabled(true);
        }

In manifest,

 <uses-permission
    android:name="android.permission.CHANGE_WIFI_STATE"
    android:required="true" />

Here's my take: http://jsfiddle.net/WojtekKruszewski/Zf3m7/22/

Sometimes while moving mouse from popover trigger to actual popover content diagonally, you hover over elements below. I wanted to handle such situations – as long as you reach popover content before the timeout fires, you're safe (the popover won't disappear). It requires delay option.

This hack basically overrides Popover leave function, but calls the original (which starts timer to hide the popover). Then it attaches a one-off listener to mouseenter popover content element's.

If mouse enters the popover, the timer is cleared. Then it turns it listens to mouseleave on popover and if it's triggered, it calls the original leave function so that it could start hide timer.

var originalLeave = $.fn.popover.Constructor.prototype.leave;
$.fn.popover.Constructor.prototype.leave = function(obj){
  var self = obj instanceof this.constructor ?
    obj : $(obj.currentTarget)[this.type](this.getDelegateOptions()).data('bs.' + this.type)
  var container, timeout;

  originalLeave.call(this, obj);

  if(obj.currentTarget) {
    container = $(obj.currentTarget).siblings('.popover')
    timeout = self.timeout;
    container.one('mouseenter', function(){
      //We entered the actual popover – call off the dogs
      clearTimeout(timeout);
      //Let's monitor popover content instead
      container.one('mouseleave', function(){
        $.fn.popover.Constructor.prototype.leave.call(self, self);
      });

I'm using this code for my sites

server {
        listen 80;
        listen 443;
        server_name  .domain.com;

        return 301 $scheme://newdomain.com$request_uri;
}

Either use:

List<string> list = new List<string>(array);

or from LINQ:

List<string> list = array.ToList();

Or change your code to not rely on the specific implementation:

IList<string> list = array; // string[] implements IList<string>

response.GetResponseStream() should be used to return the response stream. And don't forget to close the Stream and Response objects.

Option 1

If you do not need to use Authentication you can add configs to ngrok commands

ngrok http 9000 --host-header=rewrite

or

ngrok http 9000 --host-header="localhost:9000"

But in this case Authentication will not work on your website because ngrok rewriting headers and session is not valid for your ngrok domain

Option 2

If you are using webpack you can add the following configuration

devServer: {
    disableHostCheck: true
}

In that case Authentication header will be valid for your ngrok domain

Question 1 query:

SELECT ta.C1
      ,ta.C2
      ,ta.C3
      ,ta.C4
FROM [TableA] ta
WHERE (SELECT COUNT(*)
       FROM [TableA] ta2
       WHERE ta.C2=ta2.C2
       AND ta.C3=ta2.C3
       AND ta.C4=ta2.C4)>1

You can try this:

$scope.child = {} //declare it in parent controller (scope)

then in child controller (scope) add:

var parentScope = $scope.$parent;
parentScope.child = $scope;

Now the parent has access to the child's scope.

no, you need to do something like:

$('input.sitebg').val('000000');

but you should really be using unique IDs if you can.

You can also get more specific, such as:

$('input[type=text].sitebg').val('000000');

EDIT:

do this to find your input based on the name attribute:

$('input[name=sitebg]').val('000000');

Here is the complete solution for directly integrating a report-viewer control (as well as any asp.net server side control) in an MVC .aspx view, which will also work on a report with multiple pages (unlike Adrian Toman's answer) and with AsyncRendering set to true, (based on "Pro ASP.NET MVC Framework" by Steve Sanderson).

What one needs to do is basically:

1. Add a form with runat = "server"

2. Add the control, (for report-viewer controls it can also sometimes work even with AsyncRendering="True" but not always, so check in your specific case)

3. Add server side scripting by using script tags with runat = "server"

4. Override the Page_Init event with the code shown below, to enable the use of PostBack and Viewstate

Here is a demonstration:

<form ID="form1" runat="server">
    <rsweb:ReportViewer ID="ReportViewer1" runat="server" />
</form>
<script runat="server">
    protected void Page_Init(object sender, EventArgs e)
    {
        Context.Handler = Page;
    }
    //Other code needed for the report viewer here        
</script>

It is of course recommended to fully utilize the MVC approach, by preparing all needed data in the controller, and then passing it to the view via the ViewModel.

This will allow reuse of the View!

However this is only said for data this is needed for every post back, or even if they are required only for initialization if it is not data intensive, and the data also has not to be dependent on the PostBack and ViewState values.

However even data intensive can sometimes be encapsulated into a lambda expression and then passed to the view to be called there.

A couple of notes though:

• By doing this the view essentially turns into a web form with all it's drawbacks, (i.e. Postbacks, and the possibility of non Asp.NET controls getting overriden)
• The hack of overriding Page_Init is undocumented, and it is subject to change at any time

Change display:inline to display:inline-block

.test {
  width:200px;
  display:inline-block;
  overflow: auto;
  white-space: nowrap;
  margin:0px auto;
  border:1px red solid;
}

You can do this with the apksigner tool that is part of the Android SDK:

apksigner verify --print-certs my_app.apk

You can find apksigner inside the build-tools directory. For example: ~/Library/Android/sdk/build-tools/29.0.1/apksigner

I think some background backup solutions like Google Backup and Sync block access to the index file. I closed the application and Sourcetree had no issues at all. Seems that Dropbox does the same (@tonymayoral).

This code works to catch the user closing the console window:

using System;
using System.Runtime.InteropServices;

class Program {
    static void Main(string[] args) {
        handler = new ConsoleEventDelegate(ConsoleEventCallback);
        SetConsoleCtrlHandler(handler, true);
        Console.ReadLine();
    }

    static bool ConsoleEventCallback(int eventType) {
        if (eventType == 2) {
            Console.WriteLine("Console window closing, death imminent");
        }
        return false;
    }
    static ConsoleEventDelegate handler;   // Keeps it from getting garbage collected
    // Pinvoke
    private delegate bool ConsoleEventDelegate(int eventType);
    [DllImport("kernel32.dll", SetLastError = true)]
    private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);

}

Beware of the restrictions. You have to respond quickly to this notification, you've got 5 seconds to complete the task. Take longer and Windows will kill your code unceremoniously. And your method is called asynchronously on a worker thread, the state of the program is entirely unpredictable so locking is likely to be required. Do make absolutely sure that an abort cannot cause trouble. For example, when saving state into a file, do make sure you save to a temporary file first and use File.Replace().

This is how i ended up doing it.

 <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <View
                android:layout_width="20dp"
                android:layout_height="20dp"
                android:background="@drawable/circle"
                android:drawableStart="@drawable/ic_bullet_point" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="10dp"
                android:text="Your text"
                android:textColor="#000000"
                android:textSize="14sp" />
        </LinearLayout>

and the code for drawbale/circle.xml is

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:innerRadius="0dp"
  android:shape="ring"
  android:thickness="5dp"
  android:useLevel="false">

 <solid android:color="@color/black1" />

</shape>

The @Inject annotation is one of the JSR-330 annotations collection. This has Match by Type,Match by Qualifier, Match by Name execution paths. These execution paths are valid for both setter and field injection.The behavior of @Autowired annotation is same as the @Inject annotation. The only difference is the @Autowired annotation is a part of the Spring framework. @Autowired annotation also has the above execution paths. So I recommend the @Autowired for your answer.

After following the steps in Jose Alban's answer, I was able to get ImageMagick to work just fine using the following command:

convert -density 1536 -background none -resize 100x100 input.svg output-100.png

The number 1536 comes from a ballpark estimate of density, see this answer for more information.

EDIT: This answer (and most of the others) are obsolete; see Devpool's answer instead.

Originally, there were no config options to make "git diff --ignore-submodules" and "git status --ignore-submodules" the global default (but see also Setting git default flags on commands). An alternative is to set a default ignore config option on each individual submodule you want to ignore (for both git diff and git status), either in the .git/config file (local only) or .gitmodules (will be versioned by git). For example:

[submodule "foobar"]
    url = [email protected]:foo/bar.git
    ignore = untracked

ignore = untracked to ignore just untracked files, ignore = dirty to also ignore modified files, and ignore = all to ignore also commits. There's apparently no way to wildcard it for all submodules.

In my case the Exception occurred because all google play service extensions are not with same version as follows

 compile 'com.google.android.gms:play-services-plus:9.8.0'
 compile 'com.google.android.gms:play-services-appinvite:9.8.0'
 compile 'com.google.android.gms:play-services-analytics:8.3.0'

It worked when I changed this to

compile 'com.google.android.gms:play-services-plus:9.8.0'
 compile 'com.google.android.gms:play-services-appinvite:9.8.0'
 compile 'com.google.android.gms:play-services-analytics:9.8.0'

It looks funny but it works.
