Use Notification Center in the viewDidLoad: method of your ViewController to call a method and from there do what you were supposed to do in your viewWillAppear: method. Calling viewWillAppear: directly is not a good option.

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSLog(@"view did load");

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationIsActive:) 
        name:UIApplicationDidBecomeActiveNotification 
        object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationEnteredForeground:) 
        name:UIApplicationWillEnterForegroundNotification
        object:nil];
}

- (void)applicationIsActive:(NSNotification *)notification {
    NSLog(@"Application Did Become Active");
}

- (void)applicationEnteredForeground:(NSNotification *)notification {
    NSLog(@"Application Entered Foreground");
}

It's important to note that using viewDidLoad for positioning is a bit risky and should be avoided since the bounds are not set. this may cause unexpected results (I had a variety of issues...)

This post describes quite well the different methods and what happens in each of them.

currently for one-time init and positioning I'm thinking of using viewDidAppear with a flag, if anyone has any other recommendation please let me know.

Use these codes and enjoy it.

Public Function GetDirectoryName(ByVal source As String) As String()
Dim fso, oFolder, oSubfolder, oFile, queue As Collection
Set fso = CreateObject("Scripting.FileSystemObject")
Set queue = New Collection

Dim source_file() As String
Dim i As Integer        

queue.Add fso.GetFolder(source) 'obviously replace

Do While queue.Count > 0
    Set oFolder = queue(1)
    queue.Remove 1 'dequeue
    '...insert any folder processing code here...
    For Each oSubfolder In oFolder.SubFolders
        queue.Add oSubfolder 'enqueue
    Next oSubfolder
    For Each oFile In oFolder.Files
        '...insert any file processing code here...
        'Debug.Print oFile
        i = i + 1
        ReDim Preserve source_file(i)
        source_file(i) = oFile
    Next oFile
Loop
GetDirectoryName = source_file
End Function

And here you can call function:

Sub test()
Dim s
For Each s In GetDirectoryName("C:\New folder")
Debug.Print s
Next
End Sub

It will depend of your php version. Check it running:

php -version

Now, according to your current version, run:

sudo apt-get install php7.2-mysql

You need to escape the string you are writing out into DoEdit to scrub out the double-quote characters. They are causing the onclick HTML attribute to close prematurely.

Using the JavaScript escape character, \, isn't sufficient in the HTML context. You need to replace the double-quote with the proper XML entity representation, ".

The primary goal of a hashmap is to store a data set and provide near constant time lookups on it using a unique key. There are two common styles of hashmap implementation:

• Separate chaining: one with an array of buckets (linked lists)
• Open addressing: a single array allocated with extra space so index collisions may be resolved by placing the entry in an adjacent slot.

Separate chaining is preferable if the hashmap may have a poor hash function, it is not desirable to pre-allocate storage for potentially unused slots, or entries may have variable size. This type of hashmap may continue to function relatively efficiently even when the load factor exceeds 1.0. Obviously, there is extra memory required in each entry to store linked list pointers.

Hashmaps using open addressing have potential performance advantages when the load factor is kept below a certain threshold (generally about 0.7) and a reasonably good hash function is used. This is because they avoid potential cache misses and many small memory allocations associated with a linked list, and perform all operations in a contiguous, pre-allocated array. Iteration through all elements is also cheaper. The catch is hashmaps using open addressing must be reallocated to a larger size and rehashed to maintain an ideal load factor, or they face a significant performance penalty. It is impossible for their load factor to exceed 1.0.

Some key performance metrics to evaluate when creating a hashmap would include:

• Maximum load factor
• Average collision count on insertion
• Distribution of collisions: uneven distribution (clustering) could indicate a poor hash function.
• Relative time for various operations: put, get, remove of existing and non-existing entries.

Here is a flexible hashmap implementation I made. I used open addressing and linear probing for collision resolution.

Although the accepted answer works, you should really be using python's json module:

import json

score=[1,2,3,4,5]

with open("file.json", 'w') as f:
    # indent=2 is not needed but makes the file human-readable
    json.dump(score, f, indent=2) 

with open("file.json", 'r') as f:
    score = json.load(f)

print(score)

Advantages:

1. json is a widely adopted and standardized data format, so non-python programs can easily read and understand the json files
2. json files are human-readable
3. Any nested or non-nested list/dictionary structure can be saved to a json file (as long as all the contents are serializable).

Disadvantages:

1. The data is stored in plain-text (ie it's uncompressed), which makes it a slow and bloated option for large amounts of data (ie probably a bad option for storing large numpy arrays, that's what hdf5 is for).
2. The contents of a list/dictionary need to be serializable before you can save it as a json, so while you can save things like strings, ints, and floats, you'll need to write custom serialization and deserialization code to save objects, classes, and functions

When to use json vs pickle:

• If you want to store something you know you're only ever going to use in the context of a python program, use pickle
• If you need to save data that isn't serializable by default (ie objects), save yourself the trouble and use pickle.
• If you need a platform agnostic solution, use json
• If you need to be able to inspect and edit the data directly, use json

Common use cases:

• Configuration files (for example, node.js uses a package.json file to track project details, dependencies, scripts, etc ...)
• Most REST APIs use json to transmit and receive data
• Data that requires a nested list/dictionary structure, or requires variable length lists/dicts
• Can be an alternative to csv, xml or yaml files

You cannot use the datetime function using the Java wrapper "ContentValues". Either you can use :

• SQLiteDatabase.execSQL so you can enter a raw SQL query.

  mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
  

• Or the java date time capabilities :

  // set the format to sql date time
  SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
  Date date = new Date();
  ContentValues initialValues = new ContentValues(); 
  initialValues.put("date_created", dateFormat.format(date));
  long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
  

I found this version most suitable for all cases. It doesn't remove all whitespaces.

For example "a (test) b" -> "a b"

"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim(); "Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();

You can use the Sysinternals Contig tool. It has a -n switch which creates a new file of a given size. Unlike fsutil, it doesn't require administrative privileges.

I have finally managed to properly add back button to actionbar/toolbar

@Override
public void onCreate(Bundle savedInstanceState) {
    ...
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
}  

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            finish();
            return true;
    }

    return super.onOptionsItemSelected(item);
}

public boolean onCreateOptionsMenu(Menu menu) {
    return true;
}

Also works in Wampserver. Click on the Green Wampserver Icon, choose MySql, then my.ini. This will allow you to open the my.ini file. Then -

1. look up for: # The MySQL server [mysqld]
2. add this right below it: lower_case_table_names = 2
3. save the file and restart MySQL service

Important Note - add the lower_case_table_names = 2 statement NOT under the [mysql] statement, but under the [mysqld] statement

Reference - http://doc.silverstripe.org/framework/en/installation/windows-wamp

From your case, you need to set the border to none on <table> and <td> tags.

    <table width=1000 style="border:none; border-collapse:collapse; cellspacing:0; cellpadding:0" >
        <tr>
            <td style="border:none" rowspan=2>
                <img src="/Content/Images/elk_banner.jpg" />
            </td>
            <td style="border:none">
                <div id="logindisplay">
                    @Html.Partial("_LogOnPartial")
                </div>
            </td>
        </tr>
    </table>

{ find . -maxdepth 1 -type f | xargs ls -1t | less; }

added xargs to make it works, and used -1 instead of -l to show only filenames without additional ls info

On insert we can use

$arrEntity=$entity->toArray();        
    foreach ($arrEntity as $key => $value) {    
        if (trim($entity->$key) == '' && !is_null($entity->$key) && !is_bool($entity->$key)){
        unset($entity->$key);
        }
    }

On update we can use

$fields=array();
foreach ($fields as $key => $value) {
        if (trim($value) == '' && !is_null($value) && !is_bool($value)){
            $fields[$key] = null;
        }
    }

In Android Studio 1.0, this worked for me :-
Open the build.gradle (Module : app) file and paste this (at the end) :-

dependencies {
    compile "com.android.support:appcompat-v7:21.0.+"
}

Note that this dependencies is different from the dependencies inside buildscript in build.gradle (Project)
When you edit the gradle file, a message shows that you must sync the file. Press "Sync now"

Only when you multiply integer with a string, you will get repetitive string..

You can use int() factory method to create integer out of string form of integer..

>>> int('1') * int('9')
9
>>> 
>>> '1' * 9
'111111111'
>>>
>>> 1 * 9
9
>>> 
>>> 1 * '9'
'9'

• If both operand is int, you will get multiplication of them as int.
• If first operand is string, and second is int.. Your string will be repeated that many times, as the value in your integer 2nd operand.
• If first operand is integer, and second is string, then you will get multiplication of both numbers in string form..

 public function addGetParamToUrl($url, $params)
{
    foreach ($params as $param) {
         if (strpos($url, "?"))
        {
            $url .= "&" .http_build_query($param); 
        }
        else
        {
            $url .= "?" .http_build_query($param); 
        }
    }
    return $url;
}

I encountered this issue by putting a XML file into the src/main/resources wrongly, I deleted it and then all back to normal.

This works for me: This is a criteria over two fields/columns (9 and 10), this filters rows with values >0 on column 9 and rows with values 4, 7, and 8 on column 10. lastrow is the number of rows on the data section.

ActiveSheet.Range("$A$1:$O$" & lastrow).AutoFilter Field:=9, Criteria1:=">0", Operator:=xlAnd
ActiveSheet.Range("$A$1:$O$" & lastrow).AutoFilter Field:=10, Criteria1:=Arr("4","7","8"), Operator:=xlFilterValues

Try Activity#finish(). This is more or less what the back button does by default.

Look how I format my date $jour in the parameters. It depends if you use a expr()->like or a expr()->lte

$qb
        ->select('e')
        ->from('LdbPlanningBundle:EventEntity', 'e')
        ->where(
            $qb->expr()->andX(
                $qb->expr()->orX(
                    $qb->expr()->like('e.start', ':jour1'),
                    $qb->expr()->like('e.end', ':jour1'),
                    $qb->expr()->andX(
                        $qb->expr()->lte('e.start', ':jour2'),
                        $qb->expr()->gte('e.end', ':jour2')
                    )
                ),
                $qb->expr()->eq('e.user', ':user')
            )
        )
        ->andWhere('e.user = :user ')
        ->setParameter('user', $user)
        ->setParameter('jour1', '%'.$jour->format('Y-m-d').'%')
        ->setParameter('jour2', $jour->format('Y-m-d'))
        ->getQuery()
        ->getArrayResult()
    ;

If it's always going to be an even LHS/RHS split, you can also use the partition method that's built into strings. It returns a 3-tuple as (LHS, separator, RHS) if the separator is found, and (original_string, '', '') if the separator wasn't present:

>>> "2.7.0_bf4fda703454".partition('_')
('2.7.0', '_', 'bf4fda703454')

>>> "shazam".partition("_")
('shazam', '', '')

"Egg" is a single-file importable distribution format for Python-related projects.

"The Quick Guide to Python Eggs" notes that "Eggs are to Pythons as Jars are to Java..."

Eggs actually are richer than jars; they hold interesting metadata such as licensing details, release dependencies, etc.

I'd use bootstrap and set the html as:

<div class="row">
    <div class="col-md-4">
        <img src="img/logo.png" alt="logo" />
    </div>
    <div class="col-md-8">
        <h1>My website name</h1>
    </div>
</div>

Thanks for all the source code and comments - thanks to that, I finally have an app that I wanted :)

I have compiled some of the examples, and both sources and executables can be found here:

http://sdaaubckp.svn.sourceforge.net/viewvc/sdaaubckp/xp-take-screenshot/

I use InterceptCaptureScreen.exe - simply run it in a command prompt terminal, and then press Insert when you want to capture a screenshot (timestamped filenames, png, in the same directory where the executable is); keys will be captured even if the terminal is not in focus.

(I use Insert key, since it should have an easier time propagating through, say, VNC than PrintScreen - which on my laptop requires that also Fn key is pressed, and that does not propagate through VNC. Of course, its easy to change what is the actual key used in the source code).

Hope this helps, Cheers!

Had peno's version optimised a bit. The increase in performance is perceptible.

private boolean unpackZip(String path, String zipname)
{       
     InputStream is;
     ZipInputStream zis;
     try 
     {
         String filename;
         is = new FileInputStream(path + zipname);
         zis = new ZipInputStream(new BufferedInputStream(is));          
         ZipEntry ze;
         byte[] buffer = new byte[1024];
         int count;

         while ((ze = zis.getNextEntry()) != null) 
         {
             filename = ze.getName();

             // Need to create directories if not exists, or
             // it will generate an Exception...
             if (ze.isDirectory()) {
                File fmd = new File(path + filename);
                fmd.mkdirs();
                continue;
             }

             FileOutputStream fout = new FileOutputStream(path + filename);

             while ((count = zis.read(buffer)) != -1) 
             {
                 fout.write(buffer, 0, count);             
             }

             fout.close();               
             zis.closeEntry();
         }

         zis.close();
     } 
     catch(IOException e)
     {
         e.printStackTrace();
         return false;
     }

    return true;
}

I have similar solution but might be useful for pandas

import math
import re
from collections import Counter
import pandas as pd

WORD = re.compile(r"\w+")


def get_cosine(vec1, vec2):
    intersection = set(vec1.keys()) & set(vec2.keys())
    numerator = sum([vec1[x] * vec2[x] for x in intersection])

    sum1 = sum([vec1[x] ** 2 for x in list(vec1.keys())])
    sum2 = sum([vec2[x] ** 2 for x in list(vec2.keys())])
    denominator = math.sqrt(sum1) * math.sqrt(sum2)

    if not denominator:
        return 0.0
    else:
        return float(numerator) / denominator


def text_to_vector(text):
    words = WORD.findall(text)
    return Counter(words)

df=pd.read_csv('/content/drive/article.csv')
df['vector1']=df['headline'].apply(lambda x: text_to_vector(x)) 
df['vector2']=df['snippet'].apply(lambda x: text_to_vector(x)) 
df['simscore']=df.apply(lambda x: get_cosine(x['vector1'],x['vector2']),axis=1)

Try destroyDrawingCache() on ViewPager after notifyDataSetChanged() in your code.

Not pretty good solution, but you can try the hjson tool. It allows you to write text multi-lined in editor and then converts it to the proper valid JSON format.

Note: it adds '\n' characters for the new lines, but you can simply delete them in any text editor with the "Replace all.." function.

add method container css in your script like this :

$("#your_select_id").select2({
      containerCss : {"display":"block"}
});

it will set your select's width same as width your div.

The builtin SequenceMatcher is very slow on large input, here's how it can be done with diff-match-patch:

from diff_match_patch import diff_match_patch

def compute_similarity_and_diff(text1, text2):
    dmp = diff_match_patch()
    dmp.Diff_Timeout = 0.0
    diff = dmp.diff_main(text1, text2, False)

    # similarity
    common_text = sum([len(txt) for op, txt in diff if op == 0])
    text_length = max(len(text1), len(text2))
    sim = common_text / text_length

    return sim, diff

Some of the key differences are in the complexity requirements.

• A map requires O(log(N)) time for inserts and finds operations, as it's implemented as a Red-Black Tree data structure.

• An unordered_map requires an 'average' time of O(1) for inserts and finds, but is allowed to have a worst-case time of O(N). This is because it's implemented using Hash Table data structure.

So, usually, unordered_map will be faster, but depending on the keys and the hash function you store, can become much worse.

This question -- Why do Sublime Text 3 Themes not affect the sidebar? -- helped me out.

The steps I followed:

1. Preferences
2. Browse Packages...
3. Go into the User folder (equivalent to going to %AppData%\Sublime Text 3\Packages\User)
4. Make a new text file in this folder called Default.sublime-theme
5. Add JSON styles here -- for a template, check out https://gist.github.com/MrDrews/5434948

Simply add the below to your maven project pom.xml flie:

<dependencies>
          <dependency>
            <groupId>javax</groupId>
            <artifactId>javaee-web-api</artifactId>
            <version>6.0</version>
            <scope>provided</scope>
         </dependency>
  </dependencies>

This isn't sufficient: the object returned by __iter__ must implement the iteration protocol (i.e. next method). See the relevant section in the documentation.

In Python, a good practice is to "try and see" instead of "checking".

there are 2 ways start mongoDB Install location ( ex : C:/ )

first of all : copy mongoDB install folder into C:/ location then changed name to "mongodb" or something what u want. here is ex with "mongodb" name

1 : setup mongoDB is an windows service

    1.1 : Make directory name "data" in C:/ ( so we have C:/data ),after that make directory "C:/data/db" <br>
    1.2 : run in CMD ( Run as Admin) command ->  "echo logpath=C:/mongodb/log/mongo.log > C:/mongodb/mongodb.cfg" <br>
    1.3 : run in CMD (Run as Adin) command -> "C:/mongodb/bin/mongod.exe --config C:/mongodb/mongod.cfg --install" <br>
    1.4 : run command "net start MongoDB" <br>

2: a small .BAT file to start mongoDB without install copy and paste to notepad and save file with filetype ".bat" here is it :

C:\mongodb\bin\mongod.exe –dbpath=C:/mongodb/data/db
   PAUSE

if you getting error 1078 or 1087 lets remove all data in C:/data/db and restart mongoDB ( copy old data to new folder and back it up after restart mongoDB )

3 . GUI for mongoDB

i'm using rockmongo

have fun with it

Even in base Python you can do the computation in generic form

result = sum(x**2 for x in some_vector) ** 0.5

x ** 2 is surely not an hack and the computation performed is the same (I checked with cpython source code). I actually find it more readable (and readability counts).

Using instead x ** 0.5 to take the square root doesn't do the exact same computations as math.sqrt as the former (probably) is computed using logarithms and the latter (probably) using the specific numeric instruction of the math processor.

I often use x ** 0.5 simply because I don't want to add math just for that. I'd expect however a specific instruction for the square root to work better (more accurately) than a multi-step operation with logarithms.

In addition to CAST and CONVERT, if you are using Sql Server 2008, you can convert to a date type (or use that type to start with), and then optionally convert again to a varchar:

declare @myDate date
set @myDate = getdate()
print cast(@myDate as varchar(10))

output:

2012-01-17

The explicit way of saying "search until X but not including X" is:

(?:(?!X).)*

where X can be any regular expression.

In your case, though, this might be overkill - here the easiest way would be

[^z]*

This will match anything except z and therefore stop right before the next z.

So .*?quick[^z]* will match The quick fox jumps over the la.

However, as soon as you have more than one simple letter to look out for, (?:(?!X).)* comes into play, for example

(?:(?!lazy).)* - match anything until the start of the word lazy.

This is using a lookahead assertion, more specifically a negative lookahead.

.*?quick(?:(?!lazy).)* will match The quick fox jumps over the.

Explanation:

(?:        # Match the following but do not capture it:
 (?!lazy)  # (first assert that it's not possible to match "lazy" here
 .         # then match any character
)*         # end of group, zero or more repetitions.

Furthermore, when searching for keywords, you might want to surround them with word boundary anchors: \bfox\b will only match the complete word fox but not the fox in foxy.

Note

If the text to be matched can also include linebreaks, you will need to set the "dot matches all" option of your regex engine. Usually, you can achieve that by prepending (?s) to the regex, but that doesn't work in all regex engines (notably JavaScript).

Alternative solution:

In many cases, you can also use a simpler, more readable solution that uses a lazy quantifier. By adding a ? to the * quantifier, it will try to match as few characters as possible from the current position:

.*?(?=(?:X)|$)

will match any number of characters, stopping right before X (which can be any regex) or the end of the string (if X doesn't match). You may also need to set the "dot matches all" option for this to work. (Note: I added a non-capturing group around X in order to reliably isolate it from the alternation)

I don't think this question has been completely answered yet because all of the answers only give single match examples. The OP's question demonstrates the nuances of having 2 matches as well as a substring match which should not be reported because it is not a word/token.

To match multiple occurrences, one might do something like this:

iter = re.finditer(r"\bis\b", String)
indices = [m.start(0) for m in iter]

This would return a list of the two indices for the original string.

use these regx

java.time

The modern approach is with the java.time classes. These supplant the troublesome old legacy date-time classes such as Date, Calendar, and SimpleDateFormat.

Parse as a ZonedDateTime.

String input = "Mon Jun 18 00:00:00 IST 2012";
DateTimeFormatter f = DateTimeFormatter.ofPattern( "E MMM dd HH:mm:ss z uuuu" )
                                       .withLocale( Locale.US );
ZonedDateTime zdt = ZonedDateTime.parse( input , f );

Extract a date-only object, a LocalDate, without any time-of-day and without any time zone.

LocalDate ld = zdt.toLocalDate();
DateTimeFormatter fLocalDate = DateTimeFormatter.ofPattern( "dd/MM/uuuu" );
String output = ld.format( fLocalDate) ;

Dump to console.

System.out.println( "input: " + input );
System.out.println( "zdt: " + zdt );
System.out.println( "ld: " + ld );
System.out.println( "output: " + output );

input: Mon Jun 18 00:00:00 IST 2012

zdt: 2012-06-18T00:00+03:00[Asia/Jerusalem]

ld: 2012-06-18

output: 18/06/2012

See this code run live in IdeOne.com.

Poor choice of format

Your format is a poor choice for data exchange: hard to read by human, hard to parse by computer, uses non-standard 3-4 letter zone codes, and assumes English.

Instead use the standard ISO 8601 formats whenever possible. The java.time classes use ISO 8601 formats by default when parsing/generating date-time values.

Specify a proper time zone name in the format of continent/region, such as America/Montreal, Africa/Casablanca, or Pacific/Auckland. Never use the 3-4 letter abbreviation such as EST or IST as they are not true time zones, not standardized, and not even unique(!). For example, your use of IST may be Irish Standard Time, Israel Standard Time (as interpreted by java.time, seen above), or India Standard Time.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

One more possible reason if you are using Tycho and Maven to build bundles, that you have wrong execution environment (Bundle-RequiredExecutionEnvironment) in the manifest file (manifest.mf) defined. For example:

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Engine Plug-in
Bundle-SymbolicName: com.foo.bar
Bundle-Version: 4.6.5.qualifier
Bundle-Activator: com.foo.bar.Activator
Bundle-Vendor: Foobar Technologies Ltd.
Require-Bundle: org.eclipse.core.runtime,
 org.jdom;bundle-version="1.0.0",
 org.apache.commons.codec;bundle-version="1.3.0",
 bcprov-ext;bundle-version="1.47.0"
Bundle-RequiredExecutionEnvironment: JavaSE-1.5
Export-Package: ...
...
Import-Package: ...
...

In my case everything else was ok. The compiler plugins (normal maven and tycho as well) were set correctly, still m2 generated old compliance level because of the manifest. I thought I share the experience.

    Console.WriteLine("Enter your Date of Birth to Know your Current age in DD/MM/YY Format");
    string str = Console.ReadLine();
    DateTime dt1 = DateTime.Parse(str);
    DateTime dt2 = DateTime.Parse("10/06/2012");
    int result = (dt2 - dt1).Days;
    result = result / 365;
    Console.WriteLine("Your Current age is {0} years.",result);

I had a quite similar problem in a "test-utils" project (adding features, rules and assertions to JUnit) child of a parent project injecting dependencies. The class depending on the org.junit.rules package was in src/main/java.

So I added a dependency on junit without test scope and it solved the problem :

pom.xml of the test-util project :

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
</dependency>

pom.xml of the parent project :

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <scope>test</scope>
</dependency>

The is related to the ini configuration setting allow_url_fopen.

You should be aware that enable that option may make some bugs in your code exploitable.

For instance, this failure to validate input may turn into a full-fledged remote code execution vulnerability:

copy($_GET["file"], "."); 

Wrote one up myself:

I'm answering this question for the second time, because the solution I've tried that didn't work at first now works, and I can recreate the steps to make it work :)

I also had a feeling that lack of Google Play Store is a culprit here, so I've tried to install Google Play Store to the emulator by advice on this link and this link combined. I've had some difficulties, but at the end I've succeeded in installing Google Play Store and tested it by downloading some random app. But the maps activity kept displaying the message with the "Update" button. That button would take me to the store, but there I would get a message about "item not found" and maps still didn't work. At that point I gave up.

Yesterday, I've fired up the same test app by accident and it worked! I was very confused, but quickly I've made a diff from the emulator where it's working and new clean one and I've determined two apps on the working one in /data/app/ directory: com.android.vending-1.apk and com.google.android.gms-1.apk. This is strange since, when I were installing Google Play Store by instructions from those sites, I was pushing Phonesky.apk, GoogleServicesFramework.apk and GoogleLoginService.apk and to a different folder /system/app.

Anyway, now the Android Google Maps API v2 is working on my emulator. These are the steps to do this:

Create a new emulator

• For device, choose "5.1'' WVGA (480 x 800: mdpi)"
• For target, choose "Android 4.1.2 - API level 16"
• For "CPU/ABI", choose "ARM"
• Leave the rest to defaults

These are the settings that are working for me. I don't know for different ones.

Start the emulator

install com.android.vending-1.apk and com.google.android.gms-1.apk via ADB install command

Google Maps should work now in your emulator.

HttpClient 4.4 suffered from a bug in this area relating to validating possibly stale connections before returning to the requestor. It didn't validate whether a connection was stale, and this then results in an immediate NoHttpResponseException.

This issue was resolved in HttpClient 4.4.1. See this JIRA and the release notes

Seems like you use Angular 4.3 version, I also faced with same problem. Use Angular 4.0.1 and post with code by @trichetricheand and it will work. I am also not sure how to solve it on Angular 4.3 :S

This always works for me:

import android.app.Activity;
import android.content.Context;

public class yourClass {

 Context ctx;

 public yourClass (Handler handler, Context context) {
 super(handler);
    ctx = context;
 }

 //Use context (ctx) in your code like this:
 block1 = new Droid(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic), 100, 10);
 //OR
 builder.setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic));
 //OR
 final Intent intent = new Intent(ctx, MainActivity.class);
 //OR
 NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
 //ETC...

}

Not related to this question but example using a Fragment to access system resources/activity like this:

public boolean onQueryTextChange(String newText) {
 Activity activity = getActivity();
 Context context = activity.getApplicationContext();
 returnSomething(newText);
 return false;
}

View customerInfo = getActivity().getLayoutInflater().inflate(R.layout.main_layout_items, itemsLayout, false);
 itemsLayout.addView(customerInfo);

There is only so much you can do with rm() and gc(). As suggested by Gavin Simpson, even if you free the actual memory in R, Windows often won't reclaim it until you close R or it is needed because all the apparent Windows memory fills up.

This usually isn't a problem. However, if you are running large loops this can sometimes lead to fragmented memory in the long term, such that even if you free the memory and restart R - the fragmented memory may prevent you allocating large chunks of memory. Especially if other applications were allocated fragmented memory while you were running R. rm() and gc() may delay the inevitable, but more RAM is better.

Starting with Go 1.16, you can use the os.ReadDir function.

func ReadDir(name string) ([]DirEntry, error)

It reads a given directory and returns a DirEntry slice that contains the directory entries sorted by filename.

It's an optimistic function, so that, when an error occurs while reading the directory entries, it tries to return you a slice with the filenames up to the point before the error.

package main

import (
    "fmt"
    "log"
    "os"
)

func main() {
    files, err := os.ReadDir(".")
    if err != nil {
        log.Fatal(err)
    }

    for _, file := range files {
        fmt.Println(file.Name())
    }
}

Background

Go 1.16 (Q1 2021) will propose, with CL 243908 and CL 243914 , the ReadDir function, based on the FS interface:

// An FS provides access to a hierarchical file system.
//
// The FS interface is the minimum implementation required of the file system.
// A file system may implement additional interfaces,
// such as fsutil.ReadFileFS, to provide additional or optimized functionality.
// See io/fsutil for details.
type FS interface {
    // Open opens the named file.
    //
    // When Open returns an error, it should be of type *PathError
    // with the Op field set to "open", the Path field set to name,
    // and the Err field describing the problem.
    //
    // Open should reject attempts to open names that do not satisfy
    // ValidPath(name), returning a *PathError with Err set to
    // ErrInvalid or ErrNotExist.
    Open(name string) (File, error)
}

That allows for "os: add ReadDir method for lightweight directory reading":
See commit a4ede9f:

// ReadDir reads the contents of the directory associated with the file f
// and returns a slice of DirEntry values in directory order.
// Subsequent calls on the same file will yield later DirEntry records in the directory.
//
// If n > 0, ReadDir returns at most n DirEntry records.
// In this case, if ReadDir returns an empty slice, it will return an error explaining why.
// At the end of a directory, the error is io.EOF.
//
// If n <= 0, ReadDir returns all the DirEntry records remaining in the directory.
// When it succeeds, it returns a nil error (not io.EOF).
func (f *File) ReadDir(n int) ([]DirEntry, error) 

// A DirEntry is an entry read from a directory (using the ReadDir method).
type DirEntry interface {
    // Name returns the name of the file (or subdirectory) described by the entry.
    // This name is only the final element of the path, not the entire path.
    // For example, Name would return "hello.go" not "/home/gopher/hello.go".
    Name() string
    
    // IsDir reports whether the entry describes a subdirectory.
    IsDir() bool
    
    // Type returns the type bits for the entry.
    // The type bits are a subset of the usual FileMode bits, those returned by the FileMode.Type method.
    Type() os.FileMode
    
    // Info returns the FileInfo for the file or subdirectory described by the entry.
    // The returned FileInfo may be from the time of the original directory read
    // or from the time of the call to Info. If the file has been removed or renamed
    // since the directory read, Info may return an error satisfying errors.Is(err, ErrNotExist).
    // If the entry denotes a symbolic link, Info reports the information about the link itself,
    // not the link's target.
    Info() (FileInfo, error)
}

src/os/os_test.go#testReadDir() illustrates its usage:

    file, err := Open(dir)
    if err != nil {
        t.Fatalf("open %q failed: %v", dir, err)
    }
    defer file.Close()
    s, err2 := file.ReadDir(-1)
    if err2 != nil {
        t.Fatalf("ReadDir %q failed: %v", dir, err2)
    }

Ben Hoyt points out in the comments to Go 1.16 os.ReadDir:

os.ReadDir(path string) ([]os.DirEntry, error), which you'll be able to call directly without the Open dance.
So you can probably shorten this to just os.ReadDir, as that's the concrete function most people will call.

See commit 3d913a9 (Dec. 2020):

os: add ReadFile, WriteFile, CreateTemp (was TempFile), MkdirTemp (was TempDir) from io/ioutil

io/ioutil was a poorly defined collection of helpers.

Proposal #40025 moved out the generic I/O helpers to io. This CL for proposal #42026 moves the OS-specific helpers to os, making the entire io/ioutil package deprecated.

os.ReadDir returns []DirEntry, in contrast to ioutil.ReadDir's []FileInfo.
(Providing a helper that returns []DirEntry is one of the primary motivations for this change.)

For some reason

if (strictBounds.contains(map.getCenter())) return;

didnt work for me (maybe a southern hemisphere issue). I had to change it to:

    function checkBounds() {
        var c = map.getCenter(),
            x = c.lng(),
            y = c.lat(),
            maxX = strictBounds.getNorthEast().lng(),
            maxY = strictBounds.getNorthEast().lat(),
            minX = strictBounds.getSouthWest().lng(),
            minY = strictBounds.getSouthWest().lat();

        if(x < minX || x > maxX || y < minY || y > maxY) {
            if (x < minX) x = minX;
            if (x > maxX) x = maxX;
            if (y < minY) y = minY;
            if (y > maxY) y = maxY;
            map.setCenter(new google.maps.LatLng(y, x));
        }
    }

Hope it will help someone.

I had a similar issue with the iteration and I landed here. Maybe someone else is also doing the same mistake I did.

In my case, the selector was not the problem at all. The problem was that I had messed up the javascript code: I had a loop and a subloop. The subloop was also using i as a counter, instead of j, so because the subloop was overriding the value of i of the main loop, this one never got to the second iteration.

var dayContainers = document.getElementsByClassName('day-container');
for(var i = 0; i < dayContainers.length; i++) { //loop of length = 2
        var thisDayDiv = dayContainers[i];
        // do whatever

        var inputs = thisDayDiv.getElementsByTagName('input');

        for(var j = 0; j < inputs.length; j++) { //loop of length = 4
            var thisInput = inputs[j];
            // do whatever

        };

    };

if you have this error :

configure: error: Either a previously installed pkg-config or "glib-2.0 >= 2.16" could not be found. Please set GLIB_CFLAGS and GLIB_LIBS to the correct values or pass --with-internal-glib to configure to use the bundled copy.

Instead of do this command :

$ ./configure && make install

Do that :

./configure --with-internal-glib && make install

To toggle a checkbox or you can use

element.checked = !element.checked;

so you could use

if (attribute == elementName)
{
    arrChecks[i].checked = !arrChecks[i].checked;
} else {
    arrChecks[i].checked = false;
}

You can use an inline if inside your ngStyle:

[ngStyle]="styleOne?{'background-color': 'red'} : {'background-color': 'blue'}"

A batter way in my opinion is to store your background color inside a variable and then set the background-color as the variable value:

[style.background-color]="myColorVaraible"

Well, DNS should be the same worldwide, wouldn't it? Of course it can take up to a day or so until your new DNS record is propagated around the world. So either something is wrong on your colleague's end or the DNS record still takes some time...

I usually use online DNS lookup tools for that, e.g. http://network-tools.com/

It can check your HTTP header as well. Only a proxy located in Europe would be better.

QProc.StartInfo.RedirectStandardOutput = true;
QProc.Start();
// QProc.WaitForExit();
QProc.Close();

You can probably put something together with Tables table. I've never done it, but it looks like it has a column for TABLE_ROWS and one for TABLE NAME.

To get rows per table, you can use a query like this:

SELECT table_name, table_rows
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA = '**YOUR SCHEMA**';

If you are using Node.js then you can use this code to convert Uint8Array to base64

var b64 = Buffer.from(u8).toString('base64');

You can do this:

var $html = $('<iframe width="854" height="480" src="http://www.youtube.com/embed/gYKqrjq5IjU?feature=oembed" frameborder="0" allowfullscreen></iframe>');    _x000D_
var str = $html.prop('outerHTML');_x000D_
console.log(str);

• Only 1 div to clip it
• Resized to minimum width than keep correct aspect ratio
• Crop from center (vertically and horizontally, you can adjust that with the top, lef & transform)

Be careful if you're using a theme or something, they'll often declare img max-width at 100%. You got to make none. Test it out :)

I have a one-liner answer (this example gives you 999 lines of data and one header row per file)

cat bigFile.csv | parallel --header : --pipe -N999 'cat >file_{#}.csv'

https://stackoverflow.com/a/53062251/401226

int *pointer[280]; //Creates 280 pointers of type int.

In 32 bit os, 4 bytes for each pointer. so 4 * 280 = 1120 bytes.

int (*pointer)[100][280]; // Creates only one pointer which is used to point an array of [100][280] ints.

Here only 4 bytes.

Coming to your question, int (*pointer)[280]; and int (*pointer)[100][280]; are different though it points to same 2D array of [100][280].

Because if int (*pointer)[280]; is incremented, then it will points to next 1D array, but where as int (*pointer)[100][280]; crosses the whole 2D array and points to next byte. Accessing that byte may cause problem if that memory doen't belongs to your process.

I came up with

#!/bin/sh

message=`git log --format=%B origin..HEAD | sort | uniq | grep -v '^$'`
git reset --soft origin
git commit -m "$message"

Combines, sorts, unifies and remove empty lines from the commit message. I use this for local changes to a github wiki (using gollum)

I've just added a solution here (is there a way in git to list all deleted files in the repository?) for finding the commits of deleted files by using a regexp:

git log --diff-filter=D --summary | sed -n '/^commit/h;/\/some_dir\//{G;s/\ncommit \(.*\)/ \1/gp}'

This returns everything deleted within a directory named some_dir (cascading). Any sed regexp there where \/some_dir\/ is will do.

OSX (thanks to @triplee and @keif)

git log --diff-filter=D --summary | sed -n -e '/^commit/h' -e '\:/:{' -e G -e 's/\ncommit \(.*\)/ \1/gp' -e }

may be:

UIImage *img = [[UIImage alloc] init];

and when you want to change the image:

img = [UIImage imageNamed:@"nameOfPng.png"];

but the object wasn't in the same place in the memory, but if you use the pointer, the same pointer will be point to the last image loaded.

If you still want to group only by one column (as I wanted) you can nest the query:

select c1, count(*) from (select distinct c1, c2 from t) group by c1

I thought I'd share a little trick which I'm using for large number formatting. Instead of inserting commas or spaces, I insert an empty but visible span in between the "thousands". This makes thousands easily visible, but it allows to copy/paste the input in the original format, without commas/spaces.

// This function accepts an integer, and produces a piece of HTML that shows it nicely with 
// some empty space at "thousand" markers. 
// Note, these space are not spaces, if you copy paste, they will not be visible.
function valPrettyPrint(orgVal) {
  // Save after-comma text, if present
  var period = orgVal.indexOf(".");
  var frac = period >= 0 ? orgVal.substr(period) : "";
  // Work on input as an integer
  var val = "" + Math.trunc(orgVal);
  var res = "";
  while (val.length > 0) {
    res = val.substr(Math.max(0, val.length - 3), 3) + res;
    val = val.substr(0, val.length - 3);
    if (val.length > 0) {
        res = "<span class='thousandsSeparator'></span>" + res;
    }
  }
  // Add the saved after-period information
  res += frac;
  return res;
}

With this CSS:

.thousandsSeparator {
  display : inline;
  padding-left : 4px;
}

See an example JSFiddle.

If you don't have permissions to change your default DB you could manually select a different DB at the top of your queries...

If you are using the latest version of Visual Studio Code (version 1.21.1). The task.json format has changed, see here. So the answer by Fenton and by python_starter may no longer be valid.

Before starting configuration

Before you start configuring Visual Studio Code for running your Python file.

• Make sure that you have installed Python and added its executable to your system PATH.
• You must set the folder where your python source file resides as your working folder (go to File -> Open Folder to set your working folder).

Configuration steps

Now you can configure the task. The following steps will help you run your python file correctly:

1. use Ctrl+Shift+P and input task, you will see a list of options, select Tasks: Configure Task.

2. You will then be prompted create task.json from template, choose this option, and you will be prompted to choose from a list of options. Choose Others.

3. Then in the opened task.json file, use the following settings:

    {
    "version": "2.0.0",
    "tasks": [
        {
            "label": "run this script",
            "type": "shell",
            "command": "python",
            "args": [
                "${file}"
            ],
            "problemMatcher": []
        }
    ]

In the above settings, you can give a meaningful label to this task. For example, run python.

Apache commons-text now has a StringEscapeUtils.escapeJson(String).

When you return something from a then() callback, it's a bit magic. If you return a value, the next then() is called with that value. However, if you return something promise-like, the next then() waits on it, and is only called when that promise settles (succeeds/fails).

The controller function/object represents an abstraction model-view-controller (MVC). While there is nothing new to write about MVC, it is still the most significant advanatage of angular: split the concerns into smaller pieces. And that's it, nothing more, so if you need to react on Model changes coming from View the Controller is the right person to do that job.

The story about link function is different, it is coming from different perspective then MVC. And is really essential, once we want to cross the boundaries of a controller/model/view (template).

Let' start with the parameters which are passed into the link function:

function link(scope, element, attrs) {

• scope is an Angular scope object.
• element is the jqLite-wrapped element that this directive matches.
• attrs is an object with the normalized attribute names and their corresponding values.

To put the link into the context, we should mention that all directives are going through this initialization process steps: Compile, Link. An Extract from Brad Green and Shyam Seshadri book Angular JS:

Compile phase (a sister of link, let's mention it here to get a clear picture):

In this phase, Angular walks the DOM to identify all the registered directives in the template. For each directive, it then transforms the DOM based on the directive’s rules (template, replace, transclude, and so on), and calls the compile function if it exists. The result is a compiled template function,

Link phase:

To make the view dynamic, Angular then runs a link function for each directive. The link functions typically creates listeners on the DOM or the model. These listeners keep the view and the model in sync at all times.

A nice example how to use the link could be found here: Creating Custom Directives. See the example: Creating a Directive that Manipulates the DOM, which inserts a "date-time" into page, refreshed every second.

Just a very short snippet from that rich source above, showing the real manipulation with DOM. There is hooked function to $timeout service, and also it is cleared in its destructor call to avoid memory leaks

.directive('myCurrentTime', function($timeout, dateFilter) {

 function link(scope, element, attrs) {

 ...

 // the not MVC job must be done
 function updateTime() {
   element.text(dateFilter(new Date(), format)); // here we are manipulating the DOM
 }

 function scheduleUpdate() {
   // save the timeoutId for canceling
   timeoutId = $timeout(function() {
     updateTime(); // update DOM
     scheduleUpdate(); // schedule the next update
   }, 1000);
 }

 element.on('$destroy', function() {
   $timeout.cancel(timeoutId);
 });

 ...

You can use subscript syntax to retrieve a value from the dictionary for a particular key. Because it is possible to request a key for which no value exists, a dictionary’s subscript returns an optional value of the dictionary’s value type. If the dictionary contains a value for the requested key, the subscript returns an optional value containing the existing value for that key. Otherwise, the subscript returns nil:

https://developer.apple.com/documentation/swift/dictionary

if let airportName = airports["DUB"] {
    print("The name of the airport is \(airportName).")
} else {
    print("That airport is not in the airports dictionary.")
}
// prints "The name of the airport is Dublin Airport."

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

Without access to the type (and no "InternalsVisibleTo" etc) you would have to use reflection. But a better question would be: should you be accessing this data? It isn't part of the public type contract... it sounds to me like it is intended to be treated as an opaque object (for their purposes, not yours).

You've described it as a public instance field; to get this via reflection:

object obj = ...
string value = (string)obj.GetType().GetField("test").GetValue(obj);

If it is actually a property (not a field):

string value = (string)obj.GetType().GetProperty("test").GetValue(obj,null);

If it is non-public, you'll need to use the BindingFlags overload of GetField/GetProperty.

Important aside: be careful with reflection like this; the implementation could change in the next version (breaking your code), or it could be obfuscated (breaking your code), or you might not have enough "trust" (breaking your code). Are you spotting the pattern?

In XMLHttpRequest, using XMLHttpRequest.responseText may raise the exception like below

 Failed to read the \'responseText\' property from \'XMLHttpRequest\': 
 The value is only accessible if the object\'s \'responseType\' is \'\' 
 or \'text\' (was \'arraybuffer\')

Best way to access the response from XHR as follows

function readBody(xhr) {
    var data;
    if (!xhr.responseType || xhr.responseType === "text") {
        data = xhr.responseText;
    } else if (xhr.responseType === "document") {
        data = xhr.responseXML;
    } else {
        data = xhr.response;
    }
    return data;
}

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function() {
    if (xhr.readyState == 4) {
        console.log(readBody(xhr));
    }
}
xhr.open('GET', 'http://www.google.com', true);
xhr.send(null);

I had the same error. It is solved by following steps

Go to IIS -> find your site -> right click on the site -> Manage Website -> Advanced Setting -> Check your physical path is correct or not.

If it is wrong, locate the correct path. This will solve issue.

Replace

#include "Landing.h"

with

class Landing;

If you still get errors, also post Item.h, Flight.h and common.h

EDIT: In response to comment.

You will need to e.g. #include "Landing.h" from Event.cpp in order to actually use the class. You just cannot include it from Event.h

This really works!

You shouldn't use both ngRoute and UI-router. Here's a sample code for UI-router:

repoApp.config(function($stateProvider, $urlRouterProvider) {_x000D_
  _x000D_
  $stateProvider_x000D_
    .state('state1', {_x000D_
      url: "/state1",_x000D_
      templateUrl: "partials/state1.html",_x000D_
      controller: 'YourCtrl'_x000D_
    })_x000D_
    _x000D_
    .state('state2', {_x000D_
      url: "/state2",_x000D_
      templateUrl: "partials/state2.html",_x000D_
      controller: 'YourOtherCtrl'_x000D_
    });_x000D_
    $urlRouterProvider.otherwise("/state1");_x000D_
});_x000D_
//etc.

You can find a great answer on the difference between these two in this thread: What is the difference between angular-route and angular-ui-router?

You can also consult UI-Router's docs here: https://github.com/angular-ui/ui-router

For radio buttons use the following script:

var myRadio = $('input[name=meme_wall_share]');
var checkedValue = myRadio.filter(':checked').val();

You have to select the device in the schemes menu in the top left where you used to select between simulator/device. It won’t let you archive a build for the simulator.

Or you may find that if the iOS device is already selected the archive box isn’t selected when you choose “Edit Schemes” => “Build”.

var res = from s in Splitting 
          join c in Customer on s.CustomerId equals c.Id
         where c.Id == customrId
            && c.CompanyId == companyId
        select s;

Using Extension methods:

var res = Splitting.Join(Customer,
                 s => s.CustomerId,
                 c => c.Id,
                 (s, c) => new { s, c })
           .Where(sc => sc.c.Id == userId && sc.c.CompanyId == companId)
           .Select(sc => sc.s);

I erroneously created Dockerfile.txt in my working directory leading to the above-mentioned error while build

The fix was to remove the .txt extension from the file.

The file name should be Dockerfile only without any extension.

MD5 also benefits from SSE2 usage, check out BarsWF and then tell me that it doesn't. All it takes is a little assembler knowledge and you can craft your own MD5 SSE2 routine(s). For large amounts of throughput however, there is a tradeoff of the speed during hashing as opposed to the time spent rearranging the input data to be compatible with the SIMD instructions used.

For me, it was because I had deleted the hidden .git folder.

I fixed it by deleting the folder, re-cloning, and re-making the changes.

It's probably like that because of efficiency and because if you have multiple programs writing to a single TTY, this way you don't get characters on a line interlaced. So if program A and B are outputting, you'll usually get:

program A output
program B output
program B output
program A output
program B output

This stinks, but it's better than

proprogrgraam m AB  ououtputputt
prproogrgram amB A  ououtputtput
program B output

Note that it isn't even guaranteed to flush on a newline, so you should flush explicitly if flushing matters to you.

Just change the indexes. i and j....in the loop, plus if you're dealing with Strings you have to use concat and initialize the variable to an empty Strong otherwise you'll get an exception.

String string="";
for (int i = 0; i<array.length; i++){
    for (int j = 0; j<array[i].length; j++){
        string = string.concat(array[j][i]);
    } 
}
System.out.println(string)

Use (LocalDB)\MSSQLLocalDB as the server name

I have upgraded to php7.2 from php5.6

Steps which I followed.

1. Download PHP binary from here. I have downloaded VC15 x86 Thread Safe Zip file.
2. Created a backup of xampp/php folder.
3. Extract all the contents of zip file to xampp/php folder.
4. Copied php.ini (as I have modified it before and I want my configuration back, if you were using default one then skip this step.)
5. Edit below file

C:\xampp\apache\conf\extra\http-xampp.conf

5.1. Replace

LoadFile "C:/xampp/php/php5ts.dll"

LoadFile "C:/xampp/php/libpq.dll"

LoadModule php5_module "C:/xampp/php/php5apache2_4.dll"

to

LoadFile "C:/xampp/php/php7ts.dll"

LoadFile "C:/xampp/php/libpq.dll"

LoadModule php7_module "C:/xampp/php/php7apache2_4.dll"

6. Restart Apache

remap is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands, described below:

:map and :noremap are recursive and non-recursive versions of the various mapping commands. For example, if we run:

:map j gg           (moves cursor to first line)
:map Q j            (moves cursor to first line)
:noremap W j        (moves cursor down one line)

Then:

• j will be mapped to gg.
• Q will also be mapped to gg, because j will be expanded for the recursive mapping.
• W will be mapped to j (and not to gg) because j will not be expanded for the non-recursive mapping.

Now remember that Vim is a modal editor. It has a normal mode, visual mode and other modes.

For each of these sets of mappings, there is a mapping that works in normal, visual, select and operator modes (:map and :noremap), one that works in normal mode (:nmap and :nnoremap), one in visual mode (:vmap and :vnoremap) and so on.

For more guidance on this, see:

:help :map
:help :noremap
:help recursive_mapping
:help :map-modes

I can't stress that switching USB ports is key. Often front panel USB ports can be defective.

.row {
    letter-spacing: -.31em;
    word-spacing: -.43em;
}
.col-md-4 {
    float: none;
    display: inline-block;
    vertical-align: middle;
}

Note: .col-md-4 could be any grid column, its just an example here.

Just adding why and when to use Invoke().

Both Invoke() and BeginInvoke() marshal the code you specify to the dispatcher thread.

But unlike BeginInvoke(), Invoke() stalls your thread until the dispatcher executes your code. You might want to use Invoke() if you need to pause an asynchronous operation until the user has supplied some sort of feedback.

For example, you could call Invoke() to run a snippet of code that shows an OK/Cancel dialog box. After the user clicks a button and your marshaled code completes, the invoke() method will return, and you can act upon the user's response.

See Pro WPF in C# chapter 31

Yes you can solve this error by changing the port number of glassfish because the WAMP SERVER or ORACLE database software uses a port number 8080, so there is a conflict of port number.

1)open a path like C:\GlassFish_Server\glassfish\domains\domain1\config\domain.xml.

2)find out the 8080 port number with the help of ctrl+F. You will get the following code...

<network-listener protocol="http-listener-1" port="8080" name="http-listener-1" thread-pool="http-thread-pool" transport="tcp">

3) Change that port number from 8080 to 9090 or 1234 or whatever you like..

4) Save it. Open a Netbeans IDE goto the glassfish server .

5) Right click on the server -> select refresh option.

6) to check the port no. which is given by u just right click on the server-> property.

7) Start the Glassfish server . Yehhh the error is gone...

I personally tried many RegEx expressions without having found the perfect one that match all cases.

I think that regular expressions is hard to configure properly to match all cases properly. Although few persons will not like the namespace (and I was part of them), I propose something that is part of the .Net framework and give me proper results all the times in all cases (mainly managing every double quotes cases very well):

Microsoft.VisualBasic.FileIO.TextFieldParser

Found it here: StackOverflow

Example of usage:

TextReader textReader = new StringReader(simBaseCaseScenario.GetSimStudy().Study.FilesToDeleteWhenComplete);
Microsoft.VisualBasic.FileIO.TextFieldParser textFieldParser = new TextFieldParser(textReader);
textFieldParser.SetDelimiters(new string[] { ";" });
string[] fields = textFieldParser.ReadFields();
foreach (string path in fields)
{
    ...

Hope it could help.

If you can use Javascript libraries such as underscore or lodash, I recommend having a look at _.uniq function in their libraries. From lodash:

_.uniq(array, [isSorted=false], [callback=_.identity], [thisArg])

Basically, you pass in the array that in here is an object literal and you pass in the attribute that you want to remove duplicates with in the original data array, like this:

var data = [{'name': 'Amir', 'surname': 'Rahnama'}, {'name': 'Amir', 'surname': 'Stevens'}];
var non_duplidated_data = _.uniq(data, 'name'); 

UPDATE: Lodash now has introduced a .uniqBy as well.

The LayoutInflater class is used to instantiate the contents of layout XML files into their corresponding View objects.

In other words, it takes an XML file as input and builds the View objects from it.

UITableView has a property separatorInset. You can use that to set the insets of the table view separators to zero to let them span the full width of the screen.

[tableView setSeparatorInset:UIEdgeInsetsZero];

Note: If your app is also targeting other iOS versions, you should check for the availability of this property before calling it by doing something like this:

if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
    [tableView setSeparatorInset:UIEdgeInsetsZero];
}

What if the incoming changes are the ones you want? I'm unable to run svn resolve --accept theirs-full

Lets say you have span1 as <span id='span1'>my text</span>
text change events can be captured with:

$(document).ready(function(){
    $("#span1").on('DOMSubtreeModified',function(){
         // text change handler
     });

 });
 

You can use the TelephonyManager to do this:

TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE); 
String number = tm.getLine1Number();

The documentation for getLine1Number() says this method will return null if the number is "unavailable", but it does not say when the number might be unavailable.

You'll need to give your application permission to make this query by adding the following to your Manifest:

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

(You shouldn't use TelephonyManager.getDefault() to get the TelephonyManager as that is a private undocumented API call and may change in future.)

As previously mentioned the File API, along with the FileWriter and FileSystem APIs can be used to store files on a client's machine from the context of a browser tab/window.

However, there are several things pertaining to latter two APIs which you should be aware of:

• Implementations of the APIs currently exist only in Chromium-based browsers (Chrome & Opera)
• Both of the APIs were taken off of the W3C standards track on April 24, 2014, and as of now are proprietary
• Removal of the (now proprietary) APIs from implementing browsers in the future is a possibility
• A sandbox (a location on disk outside of which files can produce no effect) is used to store the files created with the APIs
• A virtual file system (a directory structure which does not necessarily exist on disk in the same form that it does when accessed from within the browser) is used represent the files created with the APIs

Here are simple examples of how the APIs are used, directly and indirectly, in tandem to do this:

BakedGoods*

bakedGoods.get({
        data: ["testFile"],
        storageTypes: ["fileSystem"],
        options: {fileSystem:{storageType: Window.PERSISTENT}},
        complete: function(resultDataObj, byStorageTypeErrorObj){}
});

Using the raw File, FileWriter, and FileSystem APIs

function onQuotaRequestSuccess(grantedQuota)
{

    function saveFile(directoryEntry)
    {

        function createFileWriter(fileEntry)
        {

            function write(fileWriter)
            {
                var dataBlob = new Blob(["Hello world!"], {type: "text/plain"});
                fileWriter.write(dataBlob);              
            }

            fileEntry.createWriter(write);
        }

        directoryEntry.getFile(
            "testFile", 
            {create: true, exclusive: true},
            createFileWriter
        );
    }

    requestFileSystem(Window.PERSISTENT, grantedQuota, saveFile);
}

var desiredQuota = 1024 * 1024 * 1024;
var quotaManagementObj = navigator.webkitPersistentStorage;
quotaManagementObj.requestQuota(desiredQuota, onQuotaRequestSuccess);

Though the FileSystem and FileWriter APIs are no longer on the standards track, their use can be justified in some cases, in my opinion, because:

• Renewed interest from the un-implementing browser vendors may place them right back on it
• Market penetration of implementing (Chromium-based) browsers is high
• Google (the main contributer to Chromium) has not given and end-of-life date to the APIs

Whether "some cases" encompasses your own, however, is for you to decide.

*BakedGoods is maintained by none other than this guy right here :)

I know of few packages that support "make uninstall" but many more that support make install DESTDIR=xxx" for staged installs.

You can use this to create a package which you install instead of installing directly from the source. I had no luck with checkinstall but fpm works very well.

This can also help you remove a package previously installed using make install. You simply force install your built package over the make installed one and then uninstall it.

For example, I used this recently to deal with protobuf-3.3.0. On RHEL7:

make install DESTDIR=dest
cd dest
fpm -f -s dir -t rpm -n protobuf -v 3.3.0 \
 --vendor "You Not RedHat" \
 --license "Google?" \
 --description "protocol buffers" \
 --rpm-dist el7 \
 -m [email protected] \
 --url "http:/somewhere/where/you/get/the/package/oritssource" \
 --rpm-autoreqprov \
 usr

 sudo rpm -i -f protobuf-3.3.0-1.el7.x86_64.rpm
 sudo rpm -e protobuf-3.3.0      

Prefer yum to rpm if you can.

On Debian9:

make install DESTDIR=dest
cd dest
fpm -f -s dir -t deb -n protobuf -v 3.3.0 \
-C `pwd` \
--prefix / \
--vendor "You Not Debian" \
--license "$(grep Copyright ../../LICENSE)" \
--description "$(cat README.adoc)" \
--deb-upstream-changelog ../../CHANGES.txt \
 --url "http:/somewhere/where/you/get/the/package/oritssource" \
 usr/local/bin \
 usr/local/lib \
 usr/local/include

 sudo apt install -f *.deb
 sudo apt-get remove protobuf

Prefer apt to dpkg where you can.

Edit: As of February, 2020, there's now a first-class UI for automatically mounting Drive.

First, open the file browser on the left hand side. It will show a 'Mount Drive' button. Once clicked, you'll see a permissions prompt to mount Drive, and afterwards your Drive files will be present with no setup when you return to the notebook. The completed flow looks like so:

The original answer follows, below. (This will also still work for shared notebooks.)

You can mount your Google Drive files by running the following code snippet:

from google.colab import drive
drive.mount('/content/drive')

Then, you can interact with your Drive files in the file browser side panel or using command-line utilities.

Here's an example notebook

TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. On Windows Server 2008, Vista, NT, 2000 and XP TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality.

I happened to have the same problem just now. However, the first few answers don't work for me.I propose a solution:change the .classpath file.For example,you can define the classpathentry node's path like this: path="src/prefix1/java" or path="src/prefix1/resources". Hope it can help.

If you wish to escape HTML in a URL:

This is probably NOT what the OP wanted (the question doesn't clearly indicate in which context the escaping is meant to be used), but Python's native library urllib has a method to escape HTML entities that need to be included in a URL safely.

The following is an example:

#!/usr/bin/python
from urllib import quote

x = '+<>^&'
print quote(x) # prints '%2B%3C%3E%5E%26'

For Temporal Tables it is a bit more complicated due to the fact there may be some foreign keys and also exception:

Drop table operation failed on table XXX because it is not a supported operation on system-versioned temporal tables

What you can use is:

-- Disable constraints (foreign keys)
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL'
GO

-- Disable system versioning (temporial tables)
EXEC sp_MSForEachTable '
 IF OBJECTPROPERTY(object_id(''?''), ''TableTemporalType'') = 2
  ALTER TABLE ? SET (SYSTEM_VERSIONING = OFF)
'
GO

-- Removing tables
EXEC sp_MSForEachTable 'DROP TABLE ?'
GO

You still need to set callback in the params:

var params = {
  'a': b,
  'token_auth': TOKEN,
  'callback': 'functionName'
};
$sce.trustAsResourceUrl(url);

$http.jsonp(url, {
  params: params
});

Where 'functionName' is a stringified reference to globally defined function. You can define it outside of your angular script and then redefine it in your module.

You do cls.isFilled = True. That overwrites the method called isFilled and replaces it with the value True. That method is now gone and you can't call it anymore. So when you try to call it again you get an error, since it's not there anymore.

The solution is use a different name for the variable than you do for the method.

Use the debugging tools supported by the browser. As mentioned above Firebug for Firefox Chrome Developer Tools from Chrome IE Developer for IE.

That way you can detect cross-browser issues. To help reduce the cross-browser issues, use a javascript framework ie jQuery, YUI, moo tools, etc.

Below is a screenshot (javascript-debug.png) of what it looks lime in Firebug.
1) hit 'F12'
2) click the 'Script' tab and 'enable it' (if you are already on your page - hit 'F5' to re-load)
3) next to the 'All' drop down, there will be another dropdown to the right. Select your javascript file from that dropdown.
In the screenshot, I've set a break-point at line 42 by 'left-mouse-click'. This will enable you to break, inspect, watch, etc.

Delete all local tags and get the list of remote tags:

git tag -l | xargs git tag -d
git fetch

Remove all remote tags

git tag -l | xargs -n 1 git push --delete origin

Clean up local tags

git tag -l | xargs git tag -d

Swift: You can do this by checking which textField is being presented.

@objc func keyboardWillShow(notification: NSNotification) {
    if self.textField.isFirstResponder == true {
        self.view.frame.origin.y -= 150
     }
}

@objc func keyboardWillHide(notification: NSNotification){
    if self.textField.isFirstResponder == true {
       self.view.frame.origin.y += 150
    }
}

result = bytes.fromhex(some_hex_string)

Just encase anyone finds this SO post when using Android Studio which includes the SDK has part of the App package (on Mac OSX).

So as @davecaunt and @user1281750 noted but insert the following line to .bash_profile

export PATH=/Applications/Android\ Studio.app/sdk/tools:/Applications/Android\ Studio.app/sdk/platform-tools:$PATH

Use:

$text = 'This is a test';
echo substr_count($text, 'is'); // 2

// So if you want to check if is exists in the text just put
// in a condition like this:
if (substr_count($text, 'is') > 0) {
    echo "is exists";
}

Although the gcc and g++ commands do very similar things, g++ is designed to be the command you'd invoke to compile a C++ program; it's intended to automatically do the right thing.

Behind the scenes, they're really the same program. As I understand, both decide whether to compile a program as C or as C++ based on the filename extension. Both are capable of linking against the C++ standard library, but only g++ does this by default. So if you have a program written in C++ that doesn't happen to need to link against the standard library, gcc will happen to do the right thing; but then, so would g++. So there's really no reason not to use g++ for general C++ development.

A ListView let you define a set of views for it and gives you a native way (WPF binding support) to control the display of ListView by using defined views.

Example:

XAML

<ListView ItemsSource="{Binding list}" Name="listv" MouseEnter="listv_MouseEnter" MouseLeave="listv_MouseLeave">
        <ListView.Resources>
            <GridView x:Key="one">
                <GridViewColumn Header="ID" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding id}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
                <GridViewColumn Header="Name" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding name}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
            <GridView x:Key="two">                    
                <GridViewColumn Header="Name" >
                    <GridViewColumn.CellTemplate>
                        <DataTemplate>
                            <TextBlock Text="{Binding name}" />
                        </DataTemplate>
                    </GridViewColumn.CellTemplate>
                </GridViewColumn>
            </GridView>
        </ListView.Resources>
        <ListView.Style>
            <Style TargetType="ListView">
                <Style.Triggers>
                    <DataTrigger Binding="{Binding ViewType}" Value="1">
                        <Setter Property="View" Value="{StaticResource one}" />
                    </DataTrigger>
                </Style.Triggers>
                <Setter Property="View" Value="{StaticResource two}" />
            </Style>
        </ListView.Style>  

Code Behind:

private int viewType;

public int ViewType
{
    get { return viewType; }
    set 
    { 
        viewType = value;
        UpdateProperty("ViewType");
    }
}        

private void listv_MouseEnter(object sender, MouseEventArgs e)
{
    ViewType = 1;
}

private void listv_MouseLeave(object sender, MouseEventArgs e)
{
    ViewType = 2;
}

OUTPUT:

Normal View: View 2 in above XAML

MouseOver View: View 1 in above XAML

If you try to achieve above in a ListBox, probably you'll end up writing a lot more code forControlTempalate/ItemTemplate of ListBox.

Was looking for a solution to this problem today. None of the above answers seemed to satisfy. I wanted a solution that could be a one liner, no conditional logic and nothing that had to be wrapped in a function.

Here's what I came up with, seems to work really well:

hostname="http://www.example.com:1234"
hostname.split("//").slice(-1)[0].split(":")[0].split('.').slice(-2).join('.')   // gives "example.com"

May look complicated at first glance, but it works pretty simply; the key is using 'slice(-n)' in a couple of places where the good part has to be pulled from the end of the split array (and [0] to get from the front of the split array).

Each of these tests return "example.com":

"http://example.com".split("//").slice(-1)[0].split(":")[0].split('.').slice(-2).join('.')
"http://example.com:1234".split("//").slice(-1)[0].split(":")[0].split('.').slice(-2).join('.')
"http://www.example.com:1234".split("//").slice(-1)[0].split(":")[0].split('.').slice(-2).join('.')
"http://foo.www.example.com:1234".split("//").slice(-1)[0].split(":")[0].split('.').slice(-2).join('.')

If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;

wget --no-verbose --no-parent --recursive --level=1\
--no-directories --user=login --password=pass ftp://ftp.myftpsite.com/

• --no-parent : Do not ever ascend to the parent directory when retrieving recursively.
• --level=depth : Specify recursion maximum depth level depth. The default maximum depth is five layers.
• --no-directories : Do not create a hierarchy of directories when retrieving recursively.

Go to menu File → Preferences → User Settings.

It will open up Default Settings and settings.json automatically. Just add the following in the settings.json file and save it. This will overwrite the default settings.

// Place your settings in this file to overwrite the default settings
{ "editor.wrappingColumn": 0 }

Try this:

<button (click)="click()">Click me</button>

<input class="txt" type="password" [(ngModel)]="input_pw" [ngClass]="{'hidden': isHidden}" />

component.ts:

isHidden: boolean = false;
click(){
    this.isHidden = !this.isHidden;
}

just another way to do it.

Label lbl = new Label();
new ToolTip().SetToolTip(lbl, "tooltip text here");

import random
import time
import sys
while True:
    x=random.randint(1,100)
    print('''Guess my number--it's from 1 to 100.''')
    z=0
    while True:
        z=z+1
        xx=int(str(sys.stdin.readline()))
        if xx > x:
            print("Too High!")
        elif xx < x:
            print("Too Low!")
        elif xx==x:
            print("You Win!! You used %s guesses!"%(z))
            print()
            break
        else:
            break

in this, I first string the number str(), which converts it into an inoperable number. Then, I int() integerize it, to make it an operable number. I just tested your problem on my IDLE GUI, and it said that 49.8 < 50.

[JsonProperty("name")]
public string name { get; set; }
[JsonProperty("Age")]
public int required { get; set; }
[JsonProperty("Location")]
public string type { get; set; }

and Remove a "{"..,

strFieldString = strFieldString.Remove(0, strFieldString.IndexOf('{'));

DeserializeObject..,

   optionsItem objActualField = JsonConvert.DeserializeObject<optionsItem(strFieldString);

Have you considered installing MacPorts 1.8.0 (release candidate), and keeping MySQL up-to-date that way? That will build MySQL for the architecture and OS that you're using, rather than installing a 10.5 version on 10.6.

Your data dictionary conteines names of form input fields, you just keep on right their values to find results. form view Header configures browser to retrieve type of data you declare. With requests library it's easy to send POST:

import requests

url = "https://bugs.python.org"
data = {'@number': 12524, '@type': 'issue', '@action': 'show'}
headers = {"Content-type": "application/x-www-form-urlencoded", "Accept":"text/plain"}
response = requests.post(url, data=data, headers=headers)

print(response.text)

More about Request object: https://requests.readthedocs.io/en/master/api/

I found another very easy way to create dictionaries using itertools.

generator=itertools.combinations_with_replacement('abcd', 4 )

This will iterate through all combinations of 'a','b','c' and 'd' and create combinations with a total length of 1 to 4. ie. a,b,c,d,aa,ab.........,dddc,dddd. generator is an itertool object and you can loop through normally like this,

for password in generator:
        ''.join(password)

Each password is infact of type tuple and you can work on them as you normally do.

Range("$A$1").Value = "'01/01/13 00:00" will do it.

Note the single quote; this will defeat automatic conversion to a number type. But is that what you really want? An alternative would be to format the cell to take a date-time value. Then drop the single quote from the string.

After fighting with this for a long time I have concluded that the spectacularly simple answer is to just fill the table with empty cells to pad out every row of the table to the same number of cells (taking colspan into account, obviously). With computer-generated HTML this is very simple to arrange, and avoids fighting with complex workarounds. Illustration follows:

<h3>Table borders belong to cells, and aren't present if there is no cell</h3>
<table style="border:1px solid red; width:100%; border-collapse:collapse;">
    <tr style="border-top:1px solid darkblue;">
        <th>Col 1<th>Col 2<th>Col 3
    <tr style="border-top:1px solid darkblue;">
        <td>Col 1 only
    <tr style="border-top:1px solid darkblue;">
        <td colspan=2>Col 1 2 only
    <tr style="border-top:1px solid darkblue;">
        <td>1<td>2<td>3

</table>


<h3>Simple solution, artificially insert empty cells</h3>

<table style="border:1px solid red; width:100%; border-collapse:collapse;">
    <tr style="border-top:1px solid darkblue;">
        <th>Col 1<th>Col 2<th>Col 3
    <tr style="border-top:1px solid darkblue;">
        <td>Col 1 only<td><td>
    <tr style="border-top:1px solid darkblue;">
        <td colspan=2>Col 1 2 only<td>
    <tr style="border-top:1px solid darkblue;">
        <td>1<td>2<td>3

</table>

Since you're using SQL 2008:

UPDATE
    table_Name

SET
    column_A  
     = CASE
        WHEN @flag = '1' THEN @new_value
        ELSE 0
    END + column_A,

    column_B  
     = CASE
        WHEN @flag = '0' THEN @new_value
        ELSE 0
    END + column_B 
WHERE
    ID = @ID

If you were using SQL 2012:

UPDATE
    table_Name
SET
    column_A  = column_A + IIF(@flag = '1', @new_value, 0),
    column_B  = column_B + IIF(@flag = '0', @new_value, 0)
WHERE
    ID = @ID

It's deprecated but it still works so you could just use it. But if you want to be completly correct, just for the completeness of it... You'd do something like following:

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    setBackgroundDrawable();
} else {
    setBackground();
}

For this to work you need to set buildTarget api 16 and min build to 7 or something similar.

For Angular users :

Since the autocomplete = 'off' ignore by new chrome versions, chrome developer suggests autocomplete= 'false | random-string', so the google chrome/modern browsers have 2 type of users helpers -

1. autocomplete='off' (which prevents last cached suggestions).
2. autocomplete = 'false | random-string' (which prevents autofill setting, since the 'random-string' is not known by the browser).

so what to do, in case of disabling both the annoying suggestions? Here is the trick:-

1. add autocomplete = 'off' in every input fields. (or simple Jquery).

Example : $("input").attr('autocomplete', 'off');

2. Remove the <form name='form-name'> tag from HTML code and add ng-form = 'form-name' in your <div> container. Adding ng-form="form-name" will also retain all your validations.

For CSS, I found that max height of 180 is better for mobile phones landscape 320 when showing browser chrome.

.scrollable-menu {
    height: auto;
    max-height: 180px;
    overflow-x: hidden;
}

Also, to add visible scrollbars, this CSS should do the trick:

.scrollable-menu::-webkit-scrollbar {
    -webkit-appearance: none;
    width: 4px;        
}    
.scrollable-menu::-webkit-scrollbar-thumb {
    border-radius: 3px;
    background-color: lightgray;
    -webkit-box-shadow: 0 0 1px rgba(255,255,255,.75);        
}

The changes are reflected here: https://www.bootply.com/BhkCKFEELL

You should use data.response in your JS instead of json.response.

I think you have added firebase json file "google-services".json with the new file. Make sure to create a new file check the link on how to create json file from firebase and it should match with your package name

Second thing is that if you are changing the package name use the option " replace in path" when you right click under files when you select project from the drop down. You have to search for package name in the whole project and replace it !

Hope this helps !

I had this error and was explicitly setting the blocksize: aesManaged.BlockSize = 128;

Once I removed that, it worked.

Yes, you can.

Let's say you got one Layout and inside that, you got many Views. So if you want to scroll to any View programmatically, you have to write the following code snippet:

For example:

content_main.xml

<ScrollView
    android:id="@+id/scrollView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <Button
            android:id="@+id/btn"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <TextView
            android:id="@+id/txtView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </LinearLayout>
</ScrollView>

MainActivity.java

ScrollView scrollView = (ScrollView) findViewById(R.id.scrollView);
Button btn = (Button) findViewById(R.id.ivEventBanner);
TextView txtView = (TextView) findViewById(R.id.ivEditBannerImage);

If you want to scroll to a specific View, let's say txtview, in this case, just write:

scrollView.smoothScrollTo(txtView.getScrollX(),txtView.getScrollY());

And you are done.

Try this:

void drawInitialNim(int num1, int num2, int num3){
    int board[3][50] = {0}; // This is a local variable. It is not possible to use it after returning from this function. 

    int i, j, k;

    for(i=0; i<num1; i++)
        board[0][i] = 'O';
    for(i=0; i<num2; i++)
        board[1][i] = 'O';
    for(i=0; i<num3; i++)
        board[2][i] = 'O';

    for (j=0; j<3;j++) {
        for (k=0; k<50; k++) {
            if(board[j][k] != 0)
                printf("%c", board[j][k]);
        }
        printf("\n");
    }
}

In C++, structs and classes are pretty much the same; the only difference is that where access modifiers (for member variables, methods, and base classes) in classes default to private, access modifiers in structs default to public.

However, in C, a struct is just an aggregate collection of (public) data, and has no other class-like features: no methods, no constructor, no base classes, etc. Although C++ inherited the keyword, it extended the semantics. (This, however, is why things default to public in structs—a struct written like a C struct behaves like one.)

While it's possible to fake some OOP in C—for instance, defining functions which all take a pointer to a struct as their first parameter, or occasionally coercing structs with the same first few fields to be "sub/superclasses"—it's always sort of bolted on, and isn't really part of the language.

xkr.us has a great discussion, with examples. To quote their summary:

The escape() method does not encode the + character which is interpreted as a space on the server side as well as generated by forms with spaces in their fields. Due to this shortcoming and the fact that this function fails to handle non-ASCII characters correctly, you should avoid use of escape() whenever possible. The best alternative is usually encodeURIComponent().

escape() will not encode: @*/+

Use of the encodeURI() method is a bit more specialized than escape() in that it encodes for URIs as opposed to the querystring, which is part of a URL. Use this method when you need to encode a string to be used for any resource that uses URIs and needs certain characters to remain un-encoded. Note that this method does not encode the ' character, as it is a valid character within URIs.

encodeURI() will not encode: ~!@#$&*()=:/,;?+'

Lastly, the encodeURIComponent() method should be used in most cases when encoding a single component of a URI. This method will encode certain chars that would normally be recognized as special chars for URIs so that many components may be included. Note that this method does not encode the ' character, as it is a valid character within URIs.

encodeURIComponent() will not encode: ~!*()'

Specify the type of the pointer to your comparison function as the 3rd type into the map, and provide the function pointer to the map constructor:
map<keyType, valueType, typeOfPointerToFunction> mapName(pointerToComparisonFunction);

Take a look at the example below for providing a comparison function to a map, with vector iterator as key and int as value.

#include "headers.h"

bool int_vector_iter_comp(const vector<int>::iterator iter1, const vector<int>::iterator iter2) {
    return *iter1 < *iter2;
}

int main() {
    // Without providing custom comparison function
    map<vector<int>::iterator, int> default_comparison;

    // Providing custom comparison function
    // Basic version
    map<vector<int>::iterator, int,
        bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2)>
        basic(int_vector_iter_comp);

    // use decltype
    map<vector<int>::iterator, int, decltype(int_vector_iter_comp)*> with_decltype(&int_vector_iter_comp);

    // Use type alias or using
    typedef bool my_predicate(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate*> with_typedef(&int_vector_iter_comp);

    using my_predicate_pointer_type = bool (*)(const vector<int>::iterator iter1, const vector<int>::iterator iter2);
    map<vector<int>::iterator, int, my_predicate_pointer_type> with_using(&int_vector_iter_comp);


    // Testing 
    vector<int> v = {1, 2, 3};

    default_comparison.insert(pair<vector<int>::iterator, int>({v.end(), 0}));

}

The following is equivalent to your second code block:

var f = function () {
        //Some logic here...
    };

var fr = f;

fr(pars);

If you want to actually pass a reference to a function to some other function, you can do something like this:

function fiz(x, y, z) {
    return x + y + z;
}

// elsewhere...

function foo(fn, p, q, r) {
    return function () {
        return fn(p, q, r);
    }
}

// finally...

f = foo(fiz, 1, 2, 3);
f(); // returns 6

You're almost certainly better off using a framework for this sort of thing, though.

Think of it like an archive. MyDB.Bak contains MyDB.mdf and MyDB.ldf.

Restore with Move to say HerDB basically grabs MyDB.mdf (and ldf) from the back up, and copies them as HerDB.mdf and ldf.

So if you already had a MyDb on the server instance you are restoring to it wouldn't be touched.

If you're using jQuery then there are a few different ways to set the disabled attribute.

var $element = $(...);
    $element.prop('disabled', true);
    $element.attr('disabled', true); 

    // The following do not require jQuery
    $element.get(0).disabled = true;
    $element.get(0).setAttribute('disabled', true);
    $element[0].disabled = true;
    $element[0].setAttribute('disabled', true);

find is the common tool for this kind of task :

find ./my_dir -mtime +10 -type f -delete

EXPLANATIONS

• ./my_dir your directory (replace with your own)
• -mtime +10 older than 10 days
• -type f only files
• -delete no surprise. Remove it to test your find filter before executing the whole command

And take care that ./my_dir exists to avoid bad surprises !

.gitkeep isn’t documented, because it’s not a feature of Git.

Git cannot add a completely empty directory. People who want to track empty directories in Git have created the convention of putting files called .gitkeep in these directories. The file could be called anything; Git assigns no special significance to this name.

There is a competing convention of adding a .gitignore file to the empty directories to get them tracked, but some people see this as confusing since the goal is to keep the empty directories, not ignore them; .gitignore is also used to list files that should be ignored by Git when looking for untracked files.

Looks like there is an issue with the code you posted. Your function to display the T&C is referencing the wrong div id. You should consider assigning the showTOC function to the onclick attribute once the document is loaded as well:

$(document).ready({
    $('a.TOClink').click(function(){
        showTOC();
    });
});

function showTOC() {
    $('#example').dialog({modal:true});
}

A more concise example which accomplishes the desired effect using the jQuery UI dialog is:

   <div id="terms" style="display:none;">
       Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.
   </div>
   <a id="showTerms" href="#">Show Terms &amp; Conditions</a>      
   <script type="text/javascript">
       $(document).ready(function(){
           $('#showTerms').click(function(){
               $('#terms').dialog({modal:true});   
           });
       });
   </script>

Yes it is implementable!

    getSupportFragmentManager()
         .beginTransaction()
         .replace(R.id.main_fragment, targetFragment, "fragment")

Because getTitle is not a string, it returns a reference or delegate to a method (if you like), if you don't explicitly call the method.

Call your method this way:

string t= obj.getTitle() ; //obj.getTitle()  says return the title string object

However, this would work:

Func<string> method = obj.getTitle; // this compiles to a delegate and points to the method

string s = method();//call the delegate or using this syntax `method.Invoke();`

How about this?

List<string> monValues = Application["mondayValues"] as List<string>;
int sum = monValues.ConvertAll(Convert.ToInt32).Sum();

I think this is what you want:

REGEX_DATE='^\d{2}[/-]\d{2}[/-]\d{4}$'

echo "$1" | grep -P -q $REGEX_DATE
echo $?

I've used the -P switch to get perl regex.

If you want to use justify align in Jupyter Notebook use the following syntax:

<p style='text-align: justify;'> Your Text </p>

For right alignment:

<p style='text-align: right;'> Your Text </p>

Referencing Bash Variables Requires Parameter Expansion

The default shell on most Linux distributions is Bash. In Bash, variables must use a dollar sign prefix for parameter expansion. For example:

x=20
y=5
expr $x / $y

Of course, Bash also has arithmetic operators and a special arithmetic expansion syntax, so there's no need to invoke the expr binary as a separate process. You can let the shell do all the work like this:

x=20; y=5
echo $((x / y))

Do you have Excel installed on the server? The interop interfaces you're using are used to automate Excel which requires that the Excel application is installed there. Each page request cycle will potentially launch a separate instance of excel.exe. I would strongly advise against doing this as part of a web application.

Why do you want to do this? If you are wanting to generate Excel documents, there are much better ways to do this, including OpenXML as mentioned elsewhere on this thread. Please do not run Excel on the server!

Here's a small piece of code that I wrote, it resizes the image to fit the container while keeping the image's original aspect ratio. It takes in as parameters the container's width, height and the image. You can modify it to fit your needs. It's simple and works fine for my applications.

private Image scaleimage(int wid, int hei, BufferedImage img){
    Image im = img;
    double scale;
    double imw = img.getWidth();
    double imh = img.getHeight();
    if (wid > imw && hei > imh){
        im = img;
    }else if(wid/imw < hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw > hei/imh){
        scale = hei/imh;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    }else if (wid/imw == hei/imh){
        scale = wid/imw;
        im = img.getScaledInstance((int) (scale*imw), (int) (scale*imh), Image.SCALE_SMOOTH);
    } 
    return im;

The Ubuntu package docker actually refers to a GUI application, not the beloved DevOps tool we've come out to look for.

The instructions for docker can be followed per instructions on the docker page here: https://docs.docker.com/engine/install/ubuntu/

=== UPDATED (thanks @Scott Stensland) ===

You now run the following install script to get docker:

`sudo curl -sSL https://get.docker.com/ | sh`

• Note: review the script on the website and make sure you have the right link before continuing since you are running this as sudo.

This will run a script that installs docker. Note the last part of the script:

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

  `sudo usermod -aG docker stens`

Remember that you will have to log out and back in for this to take effect!

To update Docker run:

`sudo apt-get update && sudo apt-get upgrade`

For more details on what's going on, See the docker install documentation or @Scott Stensland's answer below

.

=== UPDATE: For those uncomfortable w/ sudo | sh ===

Some in the comments have mentioned that it a risk to run an arbitrary script as sudo. The above option is a convenience script from docker to make the task simple. However, for those that are security-focused but don't want to read the script you can do the following:

1. Add Dependencies

sudo apt-get update; \
sudo apt-get install \
 apt-transport-https \
 ca-certificates \
 curl \
 gnupg-agent \
 software-properties-common

2. Add docker gpg key

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -

(Security check, verify key fingerprint 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88

$ sudo apt-key fingerprint 0EBFCD88

pub   rsa4096 2017-02-22 [SCEA]
      9DC8 5822 9FC7 DD38 854A  E2D8 8D81 803C 0EBF CD88
uid           [ unknown] Docker Release (CE deb) <[email protected]>
sub   rsa4096 2017-02-22 [S]

)

3. Setup Repository

sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

4. Install Docker

sudo apt-get update; \
sudo apt-get install docker-ce docker-ce-cli containerd.io

If you want to verify that it worked run: sudo docker run hello-world

The following explains why it is named like this: Why install docker on ubuntu should be `sudo apt-get install docker.io`?

I just tried using this code and @psynnott's answer was correct though I needed to know it would work repeatedly, seems to work with jquery 1.7.1 >

I modified the jfiddle to the following http://jsfiddle.net/Rjj9v/109/

$('#mytext').text('');

This is not a new answer @psynnott is correct I am just providing a more concise example that shows the textarea is still working after the clear because if you use .val("") the text area stops working

If /foo/bar is on NFS (or possibly some FUSE filesystem), that might be the problem.

Either way, adding -O / --omit-dir-times to your command line will avoid it trying to set modification times on directories.

Since PHP 5.1.0, file_put_contents() supports writing piece-by-piece by passing a stream-handle as the $data parameter:

file_put_contents("Tmpfile.zip", fopen("http://someurl/file.zip", 'r'));

From the manual:

If data [that is the second argument] is a stream resource, the remaining buffer of that stream will be copied to the specified file. This is similar with using stream_copy_to_stream().

(Thanks Hakre.)

If you want using it with parameter (ie. delete all subdirs under the given directory), then put this two lines into a *.bat or *.cmd file:

@echo off
for /f "delims=" %%d in ('dir %1 /s /b /ad ^| sort /r') do rd "%%d" 2>nul && echo rmdir %%d

and add script-path to your PATH environment variable. In this case you can call your batch file from any location (I suppose UNC path should work, too).

Eg.:

YourBatchFileName c:\temp

(you may use quotation marks if needed)

will remove all empty subdirs under c:\temp folder

YourBatchFileName

will remove all empty subdirs under the current directory.

Uninstallation :

sudo /Library/PostgreSQL/9.6/uninstall-postgresql.app/Contents/MacOS/installbuilder.sh

Removing the data file :

sudo rm -rf /Library/PostgreSQL

Removing the configs :

sudo rm /etc/postgres-reg.ini

And thats it.

As others have pointed out, LEA (load effective address) is often used as a "trick" to do certain computations, but that's not its primary purpose. The x86 instruction set was designed to support high-level languages like Pascal and C, where arrays—especially arrays of ints or small structs—are common. Consider, for example, a struct representing (x, y) coordinates:

struct Point
{
     int xcoord;
     int ycoord;
};

Now imagine a statement like:

int y = points[i].ycoord;

where points[] is an array of Point. Assuming the base of the array is already in EBX, and variable i is in EAX, and xcoord and ycoord are each 32 bits (so ycoord is at offset 4 bytes in the struct), this statement can be compiled to:

MOV EDX, [EBX + 8*EAX + 4]    ; right side is "effective address"

which will land y in EDX. The scale factor of 8 is because each Point is 8 bytes in size. Now consider the same expression used with the "address of" operator &:

int *p = &points[i].ycoord;

In this case, you don't want the value of ycoord, but its address. That's where LEA (load effective address) comes in. Instead of a MOV, the compiler can generate

LEA ESI, [EBX + 8*EAX + 4]

which will load the address in ESI.

It looks like derivedFactor from the mosaic package was designed for this. In this example, it would look something like:

library(mosaic)
myfile <- mutate(myfile, V5 = derivedFactor(
    "1" = (V1==1 & V2!=4),
    "2" = (V2==4 & V3!=1),
    .method = "first",
    .default = 0
    ))

(If you want the outcome to be numeric instead of a factor, wrap the derivedFactor with an as.numeric.)

Note that the .default option combined with .method = "first" sets the "else" condition -- this approach is described in the help file for derivedFactor.

Yes, you can. But if you have non-unique entries on your table, it will fail. Here is the how to add unique constraint on your table. If you're using PostgreSQL 9.x you can follow below instruction.

CREATE UNIQUE INDEX constraint_name ON table_name (columns);

public String withChars(String inputa) {
    String input = inputa.toLowerCase();
    StringBuilder sb = new StringBuilder();
    final char delim = '_';
    char value;
    boolean capitalize = false;
    for (int i=0; i<input.length(); ++i) {
        value = input.charAt(i);
        if (value == delim) {
            capitalize = true;
        }
        else if (capitalize) {
            sb.append(Character.toUpperCase(value));
            capitalize = false;
        }
        else {
            sb.append(value);
        }
    }

    return sb.toString();
}

public String withRegex(String inputa) {
    String input = inputa.toLowerCase();
    String[] parts = input.split("_");
    StringBuilder sb = new StringBuilder();
    sb.append(parts[0]);
    for (int i=1; i<parts.length; ++i) {
        sb.append(parts[i].substring(0,1).toUpperCase());
        sb.append(parts[i].substring(1));
    }

    return sb.toString();
}

In my case

git rm -r .

I'm assuming you figured this out already but:

Technical Reference for Log Files in Configuration Manager

That's a list of client-side logs and what they do. They are located in Windows\CCM\Logs

AppEnforce.log will show you the actual command-line executed and the resulting exit code for each Deployment Type (only for the new style ConfigMgr Applications)

This is my go-to for troubleshooting apps. Haven't really found any other logs that are exceedingly useful.

I've finally done it in this way.

Added a ServletContextListener that does the following:

public void contextInitialized(ServletContextEvent event) {
    ServletContext context = event.getServletContext();
    System.setProperty("rootPath", context.getRealPath("/"));
}

Then in the log4j.properties file:

log4j.appender.file.File=${rootPath}WEB-INF/logs/MyLog.log

By doing it in this way Log4j will write into the right folder as long as you don't use it before the "rootPath" system property has been set. This means that you cannot use it from the ServletContextListener itself but you should be able to use it from anywhere else in the app.

It should work on every web container and OS as it's not dependent on a container specific system property and it's not affected by OS specific path issues. Tested with Tomcat and Orion web containers and on Windows and Linux and it works fine so far.

What do you think?

Define an input with an onChange() method like below (in my case, childState contains the state, passed down to this child component).

<input
   ...
   value={this.props.childState.volume}
   ...
   onChange={(e) => handleChangeInteger(e, {volume: e.target.value})}
/>

One approach I used was to install validatorJS (npm install validator --save)

I then defined a function handleChangeInteger, which takes an object that will be used to change your state, in this case, {volume: e.target.value}. Note: I needed the OR condition to allow my input to be blank, otherwise it would not let the user backspace (delete) the last integer if they wanted the field blank.

const handleChangeInteger = (e, obj_to_return) => {
  if (validator.isInt(e.target.value) || e.target.value == '') {
    this.props.childSetState(obj_to_return)
  }
}

The user will now not be allowed to type anything other than backspace, 0-9, or e (this is a number..) in the input field.

I referenced this post to create my solution: https://stackoverflow.com/a/45676912/6169225

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

Obj-C way =):

NSString *inStr = [@(month) stringValue];

Same way as @loonis suggested to use TransactionTemplate one may use this helper component (Kotlin):

@Component
class TransactionalUtils {
    /**
     * Execute any [block] of code (even private methods)
     * as if it was effectively [Transactional]
     */
    @Transactional
    fun <R> executeAsTransactional(block: () -> R): R {
        return block()
    }
}

Usage:

@Service
class SomeService(private val transactionalUtils: TransactionalUtils) {

    fun foo() {
        transactionalUtils.executeAsTransactional { transactionalFoo() }
    }

    private fun transactionalFoo() {
        println("This method is executed within transaction")
    }
}

Don't know whether TransactionTemplate reuse existing transaction or not but this code definitely do.

Late to the party but I have a working solution for creating a menu horizontally with spacing. It can be easily done using == in NSLayoutConstraint

const float MENU_HEIGHT = 40;

- (UIView*) createMenuWithLabels: (NSArray *) labels
    // labels is NSArray of NSString
    UIView * backgroundView = [[UIView alloc]init];
    backgroundView.translatesAutoresizingMaskIntoConstraints = false;

    NSMutableDictionary * views = [[NSMutableDictionary alloc] init];
    NSMutableString * format = [[NSMutableString alloc] initWithString: @"H:|"];
    NSString * firstLabelKey;

    for(NSString * str in labels)
    {
        UILabel * label = [[UILabel alloc] init];
        label.translatesAutoresizingMaskIntoConstraints = false;
        label.text = str;
        label.textAlignment = NSTextAlignmentCenter;
        label.textColor = [UIColor whiteColor];
        [backgroundView addSubview: label];
        [label fixHeightToTopBounds: MENU_HEIGHT-2];
        [backgroundView addConstraints: [label fixHeightToTopBounds: MENU_HEIGHT]];
        NSString * key = [self camelCaseFromString: str];
        [views setObject: label forKey: key];
        if(firstLabelKey == nil)
        {
            [format appendString: [NSString stringWithFormat: @"[%@]", key]];
            firstLabelKey = key;
        }
        else
        {
            [format appendString: [NSString stringWithFormat: @"[%@(==%@)]", key, firstLabelKey]];
        }
    }

    [format appendString: @"|"];

    NSArray * constraints = [NSLayoutConstraint constraintsWithVisualFormat: (NSString *) format

Just for the record (took me quite a while) before Grzegorzs answer worked for me I had to install "android support repository" through the SDK Manager!

Install it and add the following code above apply plugin: 'android-library' in the build.gradle of actionbarsherlock folder!

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.+'
    }
}

You can use the maven-assembly-plugin and create a jar with all dependencies included.

Here is a piece of code that has no dependency on an external COM object (WSH), and supports 32-bit and 64-bit programs:

using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Runtime.InteropServices.ComTypes;
using System.Text;

namespace TestShortcut
{
    class Program
    {
        static void Main(string[] args)
        {
            IShellLink link = (IShellLink)new ShellLink();

            // setup shortcut information
            link.SetDescription("My Description");
            link.SetPath(@"c:\MyPath\MyProgram.exe");

            // save it
            IPersistFile file = (IPersistFile)link;
            string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
            file.Save(Path.Combine(desktopPath, "MyLink.lnk"), false);
        }
    }

    [ComImport]
    [Guid("00021401-0000-0000-C000-000000000046")]
    internal class ShellLink
    {
    }

    [ComImport]
    [InterfaceType(ComInterfaceType.InterfaceIsIUnknown)]
    [Guid("000214F9-0000-0000-C000-000000000046")]
    internal interface IShellLink
    {
        void GetPath([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszFile, int cchMaxPath, out IntPtr pfd, int fFlags);
        void GetIDList(out IntPtr ppidl);
        void SetIDList(IntPtr pidl);
        void GetDescription([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszName, int cchMaxName);
        void SetDescription([MarshalAs(UnmanagedType.LPWStr)] string pszName);
        void GetWorkingDirectory([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszDir, int cchMaxPath);
        void SetWorkingDirectory([MarshalAs(UnmanagedType.LPWStr)] string pszDir);
        void GetArguments([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszArgs, int cchMaxPath);
        void SetArguments([MarshalAs(UnmanagedType.LPWStr)] string pszArgs);
        void GetHotkey(out short pwHotkey);
        void SetHotkey(short wHotkey);
        void GetShowCmd(out int piShowCmd);
        void SetShowCmd(int iShowCmd);
        void GetIconLocation([Out, MarshalAs(UnmanagedType.LPWStr)] StringBuilder pszIconPath, int cchIconPath, out int piIcon);
        void SetIconLocation([MarshalAs(UnmanagedType.LPWStr)] string pszIconPath, int iIcon);
        void SetRelativePath([MarshalAs(UnmanagedType.LPWStr)] string pszPathRel, int dwReserved);
        void Resolve(IntPtr hwnd, int fFlags);
        void SetPath([MarshalAs(UnmanagedType.LPWStr)] string pszFile);
    }
}

plt.autoscale() worked for me.

A kotlin verison with fallback and current syntax

 fun openAppInPlayStore() {
    val uri = Uri.parse("market://details?id=" + context.packageName)
    val goToMarketIntent = Intent(Intent.ACTION_VIEW, uri)

    var flags = Intent.FLAG_ACTIVITY_NO_HISTORY or Intent.FLAG_ACTIVITY_MULTIPLE_TASK or Intent.FLAG_ACTIVITY_NEW_TASK
    flags = if (Build.VERSION.SDK_INT >= 21) {
        flags or Intent.FLAG_ACTIVITY_NEW_DOCUMENT
    } else {
        flags or Intent.FLAG_ACTIVITY_CLEAR_TASK
    }

    goToMarketIntent.addFlags(flags)

    try {
        startActivity(context, goToMarketIntent, null)
    } catch (e: ActivityNotFoundException) {
        val intent = Intent(Intent.ACTION_VIEW,
                Uri.parse("http://play.google.com/store/apps/details?id=" + context.packageName))

        startActivity(context, intent, null)
    }
}

Call dict with no parameters

new_dict = dict()

or simply write

new_dict = {}

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

There are two reasons for this error

1) In the array of import if you imported HttpModule twice

2) If you haven't import:

import { HttpModule, JsonpModule } from '@angular/http'; 

If you want then run:

npm install @angular/http

div.abc.xyz {
    /* rules go here */
}

... or simply:

.abc.xyz {
    /* rules go here */
}

$ echo "bar embarassment"|awk '{for(o=1;o<=NF;o++)if($o=="bar")$o="no bar"}1'
no bar embarassment

You can go through the below code to solve this.
