Programs & Examples On #Gwt widgets

This works for me (Ubuntu 13.10 Desktop to an Ubuntu 14.04 Server) :-

 sudo umount -f /mnt/my_share

Mounted with

 sudo mount -t cifs -o username=me,password=mine //192.168.0.111/serv_share /mnt/my_share

where serv_share is that set up and pointed to in the smb.conf file.

For Perl there's the excellent Devel::Cover module which I regularly use on my modules.

If the build and installation is managed by Module::Build you can simply run ./Build testcover to get a nice HTML site that tells you the coverage per sub, line and condition, with nice colors making it easy to see which code path has not been covered.

The easiest solution I found for this:

You are correct that ** is the power function.

^ is bitwise XOR.

% is indeed the modulus operation, but note that for positive numbers, x % m = x whenever m > x. This follows from the definition of modulus. (Additionally, Python specifies x % m to have the sign of m.)

// is a division operation that returns an integer by discarding the remainder. This is the standard form of division using the / in most programming languages. However, Python 3 changed the behavior of / to perform floating-point division even if the arguments are integers. The // operator was introduced in Python 2.6 and Python 3 to provide an integer-division operator that would behave consistently between Python 2 and Python 3. This means:

| context                                | `/` behavior   | `//` behavior |
---------------------------------------------------------------------------
| floating-point arguments, Python 2 & 3 | float division | int divison   |
---------------------------------------------------------------------------
| integer arguments, python 2            | int division   | int division  |
---------------------------------------------------------------------------
| integer arguments, python 3            | float division | int division  |

I don't know if it helps, but using jQuery, to hide an email address, I did :

    $(function() {
        // planque l'adresse mail
        var mailSplitted 
            = ['mai', 'to:mye', 'mail@', 'addre', 'ss.fr'];

        var link = mailSplitted.join('');
        link = '<a href="' + link + '"</a>';
        $('mytag').wrap(link);
    });

I hope it helps.

The following example validates an XML file and generates the appropriate error or warning.

using System;
using System.IO;
using System.Xml;
using System.Xml.Schema;

public class Sample
{

    public static void Main()
    {
        //Load the XmlSchemaSet.
        XmlSchemaSet schemaSet = new XmlSchemaSet();
        schemaSet.Add("urn:bookstore-schema", "books.xsd");

        //Validate the file using the schema stored in the schema set.
        //Any elements belonging to the namespace "urn:cd-schema" generate
        //a warning because there is no schema matching that namespace.
        Validate("store.xml", schemaSet);
        Console.ReadLine();
    }

    private static void Validate(String filename, XmlSchemaSet schemaSet)
    {
        Console.WriteLine();
        Console.WriteLine("\r\nValidating XML file {0}...", filename.ToString());

        XmlSchema compiledSchema = null;

        foreach (XmlSchema schema in schemaSet.Schemas())
        {
            compiledSchema = schema;
        }

        XmlReaderSettings settings = new XmlReaderSettings();
        settings.Schemas.Add(compiledSchema);
        settings.ValidationEventHandler += new ValidationEventHandler(ValidationCallBack);
        settings.ValidationType = ValidationType.Schema;

        //Create the schema validating reader.
        XmlReader vreader = XmlReader.Create(filename, settings);

        while (vreader.Read()) { }

        //Close the reader.
        vreader.Close();
    }

    //Display any warnings or errors.
    private static void ValidationCallBack(object sender, ValidationEventArgs args)
    {
        if (args.Severity == XmlSeverityType.Warning)
            Console.WriteLine("\tWarning: Matching schema not found.  No validation occurred." + args.Message);
        else
            Console.WriteLine("\tValidation error: " + args.Message);

    }
}

The preceding example uses the following input files.

I faced the same issue; simply you can run this on your command window:

git remote add origin https://your/repository/url

If you split on the space, you can add leading zeros using a simple function like:

function addZeros(n) {
  return (n < 10)? '00' + n : (n < 100)? '0' + n : '' + n;
}

So you can test the length of the string and if it's less than 6, split on the space, add zeros to the number, then join it back together.

Or as a regular expression:

function addZeros(s) {
  return s.replace(/ (\d$)/,' 00$1').replace(/ (\d\d)$/,' 0$1');
}

I'm sure someone can do it with one replace, not two.

Edit - examples

alert(addZeros('MR 3'));    // MR 003
alert(addZeros('MR 23'));   // MR 023
alert(addZeros('MR 123'));  // MR 123
alert(addZeros('foo bar 23'));  // foo bar 023

It will put one or two zeros infront of a number at the end of a string with a space in front of it. It doesn't care what bit before the space is.

I manually filled NAs by exporting the CSV then editing it and reimporting, as below.

Perhaps one of you experts might explain why this procedure worked so well (the first file had columns with data of types char, INT and num (floating point numbers)), which all became char type after STEP 1; but at the end of STEP 3 R correctly recognized the datatype of each column).

# STEP 1:
MainOptionFile <- read.csv("XLUopt_XLUstk_v3.csv",
                            header=T, stringsAsFactors=FALSE)
#... STEP 2:
TestFrame <- subset(MainOptionFile, str_locate(option_symbol,"120616P00034000") > 0)
write.csv(TestFrame, file = "TestFrame2.csv")
# ...
# STEP 3:
# I made various amendments to `TestFrame2.csv`, including replacing all missing data cells with appropriate numbers. I then read that amended data frame back into R as follows:    
XLU_34P_16Jun12 <- read.csv("TestFrame2_v2.csv",
                            header=T,stringsAsFactors=FALSE)

On arrival back in R, all columns had their correct measurement levels automatically recognized by R!

I had the same problem (with a version of git-recent) and discovered it was to do with color escape codes used by git. I wonder whether this could explain why this problem is occurring so commonly.

This is demonstrates what could be happening, though color is normally set in git configuration rather than the command line (otherwise it's effect would be obvious):

~/dev/trunk (master)$ git checkout `git branch -l  --color=always  | grep django-1.11`
error: pathspec 'django-1.11' did not match any file(s) known to git.
~/dev/trunk (master)$ git branch -l  --color=always  | grep django-1.11
  django-1.11
~/dev/trunk (master)$ git checkout `git branch -l  | grep django-1.11`
Switched to branch 'django-1.11'
Your branch is up-to-date with 'gerrit/django-1.11'.
~/dev/trunk (django-1.11)$ 

I figure a git config that doesn't play with the color settings should work color=auto should do the right thing. My particular issue was because the git recent I was using was defined as an alias with hard coded colors, and I was trying to build commands on top of that

No, there is no built-in support for aggregation queries right now. However there are a few things you could do.

The first is documented here. You can use transactions or cloud functions to maintain aggregate information:

This example shows how to use a function to keep track of the number of ratings in a subcollection, as well as the average rating.

exports.aggregateRatings = firestore
  .document('restaurants/{restId}/ratings/{ratingId}')
  .onWrite(event => {
    // Get value of the newly added rating
    var ratingVal = event.data.get('rating');

    // Get a reference to the restaurant
    var restRef = db.collection('restaurants').document(event.params.restId);

    // Update aggregations in a transaction
    return db.transaction(transaction => {
      return transaction.get(restRef).then(restDoc => {
        // Compute new number of ratings
        var newNumRatings = restDoc.data('numRatings') + 1;

        // Compute new average rating
        var oldRatingTotal = restDoc.data('avgRating') * restDoc.data('numRatings');
        var newAvgRating = (oldRatingTotal + ratingVal) / newNumRatings;

        // Update restaurant info
        return transaction.update(restRef, {
          avgRating: newAvgRating,
          numRatings: newNumRatings
        });
      });
    });
});

The solution that jbb mentioned is also useful if you only want to count documents infrequently. Make sure to use the select() statement to avoid downloading all of each document (that's a lot of bandwidth when you only need a count). select() is only available in the server SDKs for now so that solution won't work in a mobile app.

Open your system command prompt/terminal -> Go to your Project folder path (root project folder ) -> Execute following command : command :- gradlew clean or ./gradlew clean

Make sure that all your gradle dependencies are of same version. -> Example :- your appcompat and recyclerview dependencies should have same version.

-> Change your gradle dependencies to same version like :-

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:design:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:cardview-v7:23.4.0'

-> Rebuild your project and it will work fine.

Typescript is (a superset of) javascript, so you just use JSON.parse as you would in javascript:

let obj = JSON.parse(jsonString);

Only that in typescript you can have a type to the resulting object:

interface MyObj {
    myString: string;
    myNumber: number;
}

let obj: MyObj = JSON.parse('{ "myString": "string", "myNumber": 4 }');
console.log(obj.myString);
console.log(obj.myNumber);

(code in playground)

As Peter and Amro illustrate, you have to convert numeric values to formatted strings first in order to display them or concatenate them with other character strings. You can do this using the functions FPRINTF, SPRINTF, NUM2STR, and INT2STR.

With respect to getting ans = 3 as an output, it is probably because you are not assigning the output from answer to a variable. If you want to get all of the output values, you will have to call answer in the following way:

[out1,out2,out3] = answer(1,2);

This will place the value d in out1, the value e in out2, and the value f in out3. When you do the following:

answer(1,2)

MATLAB will automatically assign the first output d (which has the value 3 in this case) to the default workspace variable ans.

With respect to suggesting a good resource for learning MATLAB, you shouldn't underestimate the value of the MATLAB documentation. I've learned most of what I know on my own using it. You can access it online, or within your copy of MATLAB using the functions DOC, HELP, or HELPWIN.

Try this code,

SELECT 
       * 
FROM 
       `customers` 
WHERE 
       (
          CONVERT 
               (`customer_code` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`customer_name` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`email_id` USING utf8mb4) LIKE '%Mary%' 
          OR 
          CONVERT(`address1` USING utf8mb4) LIKE '%Mary%' 
          OR
          CONVERT(`report_sorting` USING utf8mb4) LIKE '%Mary%'
       )

This is help to solve your problem mysql version 5.7.21

Yes, it's OK - it's just like using it in an if statement. Of course, you can't use a break to break out of a loop from inside a switch.

Straight from the docs

join([timeout]) Wait until the thread terminates. This blocks the calling thread until the thread whose join() method is called terminates – either normally or through an unhandled exception – or until the optional timeout occurs.

This means that the main thread which spawns t and d, waits for t to finish until it finishes.

Depending on the logic your program employs, you may want to wait until a thread finishes before your main thread continues.

Also from the docs:

A thread can be flagged as a “daemon thread”. The significance of this flag is that the entire Python program exits when only daemon threads are left.

A simple example, say we have this:

def non_daemon():
    time.sleep(5)
    print 'Test non-daemon'

t = threading.Thread(name='non-daemon', target=non_daemon)

t.start()

Which finishes with:

print 'Test one'
t.join()
print 'Test two'

This will output:

Test one
Test non-daemon
Test two

Here the master thread explicitly waits for the t thread to finish until it calls print the second time.

Alternatively if we had this:

print 'Test one'
print 'Test two'
t.join()

We'll get this output:

Test one
Test two
Test non-daemon

Here we do our job in the main thread and then we wait for the t thread to finish. In this case we might even remove the explicit joining t.join() and the program will implicitly wait for t to finish.

When you want to show years and the remaining days:

var m = moment(d.birthday.date, "DD.MM.YYYY");
var years = moment().diff(m, 'years', false);
var days = moment().diff(m.add(years, 'years'), 'days', false);
alert(years + ' years, ' + days + ' days');

You should use this one too:

./gradlew :app:dependencies (Mac and Linux) -With ./

gradlew :app:dependencies (Windows) -Without ./

The libs you are using internally using any other versions of google play service.If yes then remove or update those libs.

            memoryStream = new MemoryStream(cipherTextBytes);

            // Define memory stream which will be used to hold encrypted data.
            CryptoStream cryptoStream = default(CryptoStream);
            cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read);

            // Since at this point we don't know what the size of decrypted data
            // will be, allocate the buffer long enough to hold ciphertext;
            // plaintext is never longer than ciphertext.
            byte[] plainTextBytes = null;
            plainTextBytes = new byte[cipherTextBytes.Length + 1];

            // Start decrypting.
            int decryptedByteCount = 0;
            decryptedByteCount = cryptoStream.Read(plainTextBytes, 0, plainTextBytes.Length);

            // Close both streams.
            memoryStream.Close();
            cryptoStream.Close();

            // Convert decrypted data into a string.
            // Let us assume that the original plaintext string was UTF8-encoded.
            string plainText = null;
            plainText = Encoding.UTF8.GetString(plainTextBytes, 0, decryptedByteCount);

            // Return decrypted string.
            functionReturnValue = plainText;


        return functionReturnValue;
    }
}

While both solutions provided by Dheeraj Bhaskar work, unfortunately they will result in the UAC dialog showing up on top (z-order-wise) but not getting focused (the focused window is the caller cmd/powershell window), thus I either need to grab the mouse and click "yes", or to select the UAC window using Alt+Shift+Tab. (Tested on Win10x64 v1607 build14393.447; UAC = "[...] do not dim [...]".)

The following solution is a bit awkward as it uses two files, but it preserves the correct focus order, so no extra mouse / keyboard actions are required (besides confirming the UAC dialog: Alt+Y).

1. cmdadm.lnk (shortcut properties / Advanced... / Run as administrator = ON) %SystemRoot%\System32\cmd.exe /k "cd /d"
2. su.bat @start cmdadm.lnk %cd%

Run with su.

@jason-mccreary is totally right. Besides I recommend you this code to get more info in case of malfunction:

$rest = curl_exec($crl);

if ($rest === false)
{
    // throw new Exception('Curl error: ' . curl_error($crl));
    print_r('Curl error: ' . curl_error($crl));
}

curl_close($crl);
print_r($rest);

EDIT 1

To debug you can set CURLOPT_HEADER to true to check HTTP response with firebug::net or similar.

curl_setopt($crl, CURLOPT_HEADER, true);

EDIT 2

About Curl error: SSL certificate problem, verify that the CA cert is OK try adding this headers (just to debug, in a production enviroment you should keep these options in true):

curl_setopt($crl, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($crl, CURLOPT_SSL_VERIFYPEER, false);

It is not an anti-pattern to call setState in componentDidMount. In fact, ReactJS provides an example of this in their documentation:

You should populate data with AJAX calls in the componentDidMount lifecycle method. This is so you can use setState to update your component when the data is retrieved.

Example From Doc

componentDidMount() {
    fetch("https://api.example.com/items")
      .then(res => res.json())
      .then(
        (result) => {
          this.setState({
            isLoaded: true,
            items: result.items
          });
        },
        // Note: it's important to handle errors here
        // instead of a catch() block so that we don't swallow
        // exceptions from actual bugs in components.
        (error) => {
          this.setState({
            isLoaded: true,
            error
          });
        }
      )
  }

SELECT Code,Description FROM TABLE

--WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate < DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

As far as I know there is not "an IDE" for Django, but there are some IDEs that support Django right out of the box, specifically the Django syntax for templates.

The name is Komodo, and it has a lot of features, but it's not cheap. If you are not worried about source control or debugging then there is a free version called Komodo Edit.

That would be the modulo operator, which produces the remainder of the division of two numbers.

1. Both module.exports and exports point to the same function database_module(cfg) {...}.

   1| var a, b;
   2| a = b = function() { console.log("Old"); };
   3|     b = function() { console.log("New"); };
   4|
   5| a(); // "Old"
   6| b(); // "New"
   

   You can change b on line 3 to a, the output is reverse. The conclusion is:

   a and b are independent.

2. So module.exports = exports = nano = function database_module(cfg) {...} is equivalent to:

   var f = function database_module(cfg) {...};
   module.exports = f;
   exports = f;
   

   Assumed the above is module.js, which is required by foo.js. The benefits of module.exports = exports = nano = function database_module(cfg) {...} is clear now:

   • In foo.js, since module.exports is require('./module.js'):

     var output = require('./modules.js')();
     

   • In moduls.js: You can use exports instead of module.exports.

So, you will be happy if both exports and module.exports pointing to the same thing.

$ which pip

or

 $ pip -V 

execute this command into your terminal. It should display the location of executable file eg. /usr/local/bin/pip and the second command will display the version if the pip is installed correctly.

Same as the answer from 'Richie' but a bit more concise.

1. Query for user constraints only

   SELECT column_name FROM all_cons_columns WHERE constraint_name = (
     SELECT constraint_name FROM user_constraints 
     WHERE UPPER(table_name) = UPPER('tableName') AND CONSTRAINT_TYPE = 'P'
   );
   

2. Query for all constraints

   SELECT column_name FROM all_cons_columns WHERE constraint_name = (
     SELECT constraint_name FROM all_constraints 
     WHERE UPPER(table_name) = UPPER('tableName') AND CONSTRAINT_TYPE = 'P'
   );
   

You kill a session like this:

Session.Abandon()

If, however, you just want to empty the session, use:

Session.Clear()

I ended up packaging this into an extension method so (1) I could generate the label and radio at once and (2) so I didn't have to fuss with specifying my own IDs:

public static class HtmlHelperExtensions
{
    public static MvcHtmlString RadioButtonAndLabelFor<TModel, TProperty>(this HtmlHelper<TModel> self, Expression<Func<TModel, TProperty>> expression, bool value, string labelText)
    {
        // Retrieve the qualified model identifier
        string name = ExpressionHelper.GetExpressionText(expression);
        string fullName = self.ViewContext.ViewData.TemplateInfo.GetFullHtmlFieldName(name);

        // Generate the base ID
        TagBuilder tagBuilder = new TagBuilder("input");
        tagBuilder.GenerateId(fullName);
        string idAttr = tagBuilder.Attributes["id"];

        // Create an ID specific to the boolean direction
        idAttr = String.Format("{0}_{1}", idAttr, value);

        // Create the individual HTML elements, using the generated ID
        MvcHtmlString radioButton = self.RadioButtonFor(expression, value, new { id = idAttr });
        MvcHtmlString label = self.Label(idAttr, labelText);

        return new MvcHtmlString(radioButton.ToHtmlString() + label.ToHtmlString());
    }
}

Usage:

@Html.RadioButtonAndLabelFor(m => m.IsMarried, true, "Yes, I am married")

React Native hasn't provided the gradient color yet. But still, you can do it with a nmp package called react-native-linear-gradient or you can click here for more info

1. npm install react-native-linear-gradient --save
2. use import LinearGradient from 'react-native-linear-gradient'; in your application file

3.         <LinearGradient colors={['#4c669f', '#3b5998', '#192f6a']}>
             <Text>
               Your Text Here
             </Text>
           </LinearGradient> 

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

Set your editor to point to this program:

/Applications/TextEdit.app/Contents/MacOS/TextEdit

With SVN, you should set SVN_EDITOR environment variable to:

$ export SVN_EDITOR=/Applications/TextEdit.app/Contents/MacOS/TextEdit

And then, when you try committing something, TextEdit will launch.

You can't load a controller from a controller in CI - unless you use HMVC or something.

You should think about your architecture a bit. If you need to call a controller method from another controller, then you should probably abstract that code out to a helper or library and call it from both controllers.

UPDATE

After reading your question again, I realize that your end goal is not necessarily HMVC, but URI manipulation. Correct me if I'm wrong, but it seems like you're trying to accomplish URLs with the first section being the method name and leave out the controller name altogether.

If this is the case, you'd get a cleaner solution by getting creative with your routes.

For a really basic example, say you have two controllers, controller1 and controller2. Controller1 has a method method_1 - and controller2 has a method method_2.

You can set up routes like this:

$route['method_1'] = "controller1/method_1";
$route['method_2'] = "controller2/method_2";

Then, you can call method 1 with a URL like http://site.com/method_1 and method 2 with http://site.com/method_2.

Albeit, this is a hard-coded, very basic, example - but it could get you to where you need to be if all you need to do is remove the controller from the URL.

You could also go with remapping your controllers.

From the docs: "If your controller contains a function named _remap(), it will always get called regardless of what your URI contains.":

public function _remap($method)
{
    if ($method == 'some_method')
    {
        $this->$method();
    }
    else
    {
        $this->default_method();
    }
}

Spring has MockHttpServletRequest in its spring-test module.

If you are using maven you may need to add the appropriate dependency to your pom.xml. You can find spring-test at mvnrepository.com.

The error is pretty straightforward. Most likely the reason is that your index.html file is not in the root directory.

Or if it is in the root directory then the relative referencing is not working.

So you need to tell the server exact location of your file. This could be done by using dirname method in NodeJs. Just replace your code with this one:

 app.get('/', function(req, res){
  res.sendFile(__dirname + '/index.html');
});

Make sure that your add the slash "/" symbol before your homepage. Otherwise your path will become: rootDirectoryindex.html

Whereas you want it to be: rootDirectory/index.html

You should be able to do the following:

$params = @{"@type"="login";
 "username"="[email protected]";
 "password"="yyy";
}

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body $params

This will send the post as the body. However - if you want to post this as a Json you might want to be explicit. To post this as a JSON you can specify the ContentType and convert the body to Json by using

Invoke-WebRequest -Uri http://foobar.com/endpoint -Method POST -Body ($params|ConvertTo-Json) -ContentType "application/json"

Extra: You can also use the Invoke-RestMethod for dealing with JSON and REST apis (which will save you some extra lines for de-serializing)

Here is a short code snippet for shadowing cin/cout useful for programming contests:

#include <bits/stdc++.h>

using namespace std;

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    int a, b;   
    cin >> a >> b;
    cout << a + b << endl;
}

This gives additional benefit that plain fstreams are faster than synced stdio streams. But this works only for the scope of single function.

Global cin/cout redirect can be written as:

#include <bits/stdc++.h>

using namespace std;

void func() {
    int a, b;
    std::cin >> a >> b;
    std::cout << a + b << endl;
}

int main() {
    ifstream cin("input.txt");
    ofstream cout("output.txt");

    // optional performance optimizations    
    ios_base::sync_with_stdio(false);
    std::cin.tie(0);

    std::cin.rdbuf(cin.rdbuf());
    std::cout.rdbuf(cout.rdbuf());

    func();
}

Note that ios_base::sync_with_stdio also resets std::cin.rdbuf. So the order matters.

See also Significance of ios_base::sync_with_stdio(false); cin.tie(NULL);

Std io streams can also be easily shadowed for the scope of single file, which is useful for competitive programming:

#include <bits/stdc++.h>

using std::endl;

std::ifstream cin("input.txt");
std::ofstream cout("output.txt");

int a, b;

void read() {
    cin >> a >> b;
}

void write() {
    cout << a + b << endl;
}

int main() {
    read();
    write();
}

But in this case we have to pick std declarations one by one and avoid using namespace std; as it would give ambiguity error:

error: reference to 'cin' is ambiguous
     cin >> a >> b;
     ^
note: candidates are: 
std::ifstream cin
    ifstream cin("input.txt");
             ^
    In file test.cpp
std::istream std::cin
    extern istream cin;  /// Linked to standard input
                   ^

As of Visual Studio 2012, Microsoft no longer provides the built-in deployment package. If you wish to use this package, you will need to use VS2010.

In 2013 you have several options:

• InstallShield
• WiX
• Roll your own

In my projects I create my own installers from scratch, which, since I do not use Windows Installer, have the advantage of being super fast, even on old machines.

There you go , i hope this helps

The issue is two-fold:

1. WordPress reformats the YouTube link
2. You need a custom embed link to support a live stream embed

As a prerequisite (as of August, 2016), you need to link an AdSense account and then turn on monetization in your YouTube channel. It's a painful change that broke a lot of live streams.

You will need to use the following URL format for the embed:

<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>

The &autoplay=1 is not necessary, but I like to include it. Change CHANNEL to your channel's ID. One thing to note is that WordPress may reformat the URL once you commit your change. Therefore, you'll need a plugin that allows you to use raw code and not have it override. Using a custom PHP code plugin can help and you would just echo the code like so:

<?php echo '<iframe width="560" height="315" src="https://www.youtube.com/embed/live_stream?channel=CHANNEL_ID&autoplay=1" frameborder="0" allowfullscreen></iframe>'; ?>

Let me know if that worked for you!

It is possible to use the old Excel 2003 XML format (before OpenXML) to create a string that contains your desired XML, then on the client side you could use a data URI to open the file using the XSL mime type, or send the file to the client using the Excel mimetype "Content-Type: application/vnd.ms-excel" from the server side.

1. Open Excel and create a worksheet with your desired formatting and colors.
2. Save the Excel workbook as "XML Spreadsheet 2003 (*.xml)"
3. Open the resulting file in a text editor like notepad and copy the value into a string in your application
4. Assuming you use the client side approach with a data uri the code would look like this:

   
   <script type="text/javascript">
   var worksheet_template = '<?xml version="1.0"?><ss:Workbook xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet">'+
                '<ss:Styles><ss:Style ss:ID="1"><ss:Font ss:Bold="1"/></ss:Style></ss:Styles><ss:Worksheet ss:Name="Sheet1">'+
                '<ss:Table>{{ROWS}}</ss:Table></ss:Worksheet></ss:Workbook>';
   var row_template = '<ss:Row ss:StyleID="1"><ss:Cell><ss:Data ss:Type="String">{{name}}</ss:Data></ss:Cell></ss:Row>';
   </script>
   
   

5. Then you can use string replace to create a collection of rows to be inserted into your worksheet template

   
   <script type="text/javascript">
   var rows = document.getElementById("my-table").getElementsByTagName('tr'),
     row_data = '';
   for (var i = 0, length = rows.length; i < length; ++i) {
   row_data += row_template.replace('{{name}}', rows[i].getElementsByTagName('td')[0].innerHTML);
   }
   </script>
   
   

6. Once you have the information collected, create the final string and open a new window using the data URI

   
   <script type="text/javascript">
   var worksheet = worksheet_template.replace('{{ROWS}}', row_data);
   
   window.open('data:application/vnd.ms-excel,'+worksheet);
   </script>
   
   

It is worth noting that older browsers do not support the data URI scheme, so you may need to produce the file server side for those browser that do not support it.

You may also need to perform base64 encoding on the data URI content, which may require a js library, as well as adding the string ';base64' after the mime type in the data URI.

It is, generally speaking, a bad idea to compare $(foo) with $(foo) as that is functionally equivalent to the following comparison:

<html>
<head>
<script language='javascript'>
    function foo(bar) {
        return ({ "object": bar });
    }

    $ = foo;

    if ( $("a") == $("a") ) {
        alert ("JS engine screw-up");
    }
    else {
        alert ("Expected result");
    }

</script>

</head>
</html>

Of course you would never expect "JS engine screw-up". I use "$" just to make it clear what jQuery is doing.

Whenever you call $("#foo") you are actually doing a jQuery("#foo") which returns a new object. So comparing them and expecting same object is not correct.

However what you CAN do may be is something like:

<html>
<head>
<script language='javascript'>
    function foo(bar) {
        return ({ "object": bar });
    }

    $ = foo;

    if ( $("a").object == $("a").object ) {
        alert ("Yep! Now it works");
    }
    else {
        alert ("This should not happen");
    }

</script>

</head>
</html>

So really you should perhaps compare the ID elements of the jQuery objects in your real program so something like

... 
$(someIdSelector).attr("id") == $(someOtherIdSelector).attr("id")

is more appropriate.

Place this on your model:

[DisplayName("Electric Fan")]
public bool ElectricFan { get; set; }

private string electricFanRate;

public string ElectricFanRate
{
    get { return electricFanRate ?? (electricFanRate = "$15/month"); }
    set { electricFanRate = value; }
}

And this in your cshtml:

<div class="row">
    @Html.CheckBoxFor(m => m.ElectricFan, new { @class = "" })
    @Html.LabelFor(m => m.ElectricFan, new { @class = "" })
    @Html.DisplayTextFor(m => m.ElectricFanRate)
</div>

Which will output this:

If you click on the checkbox or the bold label it will check/uncheck the checkbox

It's as simple as adding a line to your ~/.vimrc:

colorscheme color_scheme_name

I was stuck in same problem for many hours. I tried everything found on internet.

At last, I figured out a surprising solution : I had missed \SQLEXPRESS part of the Server name: MY-COMPUTER-NAME\SQLEXPRESS

I hope this helps someone who is stuck in similar kind of problem.

enum MyEnum {
    A(0),
    B(1);
    private final int value;
    private MyEnum(int val) {this.value = value;}
    private static final MyEnum[] values = MyEnum.values();//cache for optimization
    public static final getMyEnum(int value) { 
        try {
            return values[value];//OOB might get triggered
        } catch (ArrayOutOfBoundsException e) {
        } finally {
            return myDefaultEnumValue;
        }
    }
}

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

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

This will NOT work. :

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

To fix this, just use template strings instead :

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

webpack.config.js :

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

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

This might be known by most of us, but anyway (I was puzzled my first time): Doing :set et (:set expandtabs) does not change the tabs already existing in the file, one has to do :retab. For example:

:set et
:retab

and the tabs in the file are replaced by enough spaces. To have tabs back simply do:

:set noet
:retab

Check if you do not have declared the method getAll() in the model. That causes the controller to think that you are calling a non-static method.

In order for it to display the JSON message properly it has to have the "application/json" mime type and to be correctly structured.

You can check the structure here

Since someone mentioned efficiency, I've benchmarked the functions given so far out of curiosity:

function startsWith1($str, $char) {
    return strpos($str, $char) === 0;
}
function startsWith2($str, $char) {
    return stripos($str, $char) === 0;
}
function startsWith3($str, $char) {
    return substr($str, 0, 1) === $char;
}
function startsWith4($str, $char){
    return $str[0] === $char;
}
function startsWith5($str, $char){
    return (bool) preg_match('/^' . $char . '/', $str);
}
function startsWith6($str, $char) {
    if (is_null($encoding)) $encoding = mb_internal_encoding();
    return mb_substr($str, 0, mb_strlen($char, $encoding), $encoding) === $char;
}

As you can see, treating the haystack as array to find out the char at the first position is always the fastest solution. It is also always performing at equal speed, regardless of string length. Using strpos is faster than substr for short strings but slower for long strings, when the string does not start with the prefix. The difference is irrelevant though. stripos is incredibly slow with long strings. preg_match performs mostly the same regardless of string length, but is only mediocre in speed. The mb_substr solution performs worst, while probably being more reliable though.

Given that these numbers are for 100.000 runs, it should be obvious that we are talking about 0.0000x seconds per call. Picking one over the other for efficiency is a worthless micro-optimization, unless your app is doing startsWith checking for a living.

In-Short Differences are

1) PCL is not going to have Full Access to .NET Framework , where as SharedProject has.

2) #ifdef for platform specific code - you can not write in PCL (#ifdef option isn’t available to you in a PCL because it’s compiled separately, as its own DLL, so at compile time (when the #ifdef is evaluated) it doesn’t know what platform it will be part of. ) where as Shared project you can.

3) Platform specific code is achieved using Inversion Of Control in PCL , where as using #ifdef statements you can achieve the same in Shared Project.

An excellent article which illustrates differences between PCL vs Shared Project can be found at the following link

http://hotkrossbits.com/2015/05/03/xamarin-forms-pcl-vs-shared-project/

In order to represent a single digit in the form of a regular expression you can use either:

[0-9] or \d

In order to specify how many times the number appears you would add

[0-9]*: the star means there are zero or more digits

[0-9]{2}: {N} means N digits

[0-9]{0,2}: {N,M} N digits or M digits

[0-9]{0-9}: {N-M} N digits to M digits. Note: M can be left blank for an infinite representation

Lets say I want to represent a number between 1 and 99 I would express it as such:

[0-9]{1-2} or [0-9]{1,2} or \d{1-2} or \d{1,2}

Or lets say we were working with binary display, displaying a byte size, we would want our digits to be between 0 and 1 and length of a byte size, 8, so we would represent it as follows:

[0-1]{8} representation of a binary byte

Then if you want to add a , or a . symbol you would use:

\, or \. or you can use [.] or [,]

You can also state a selection between possible values as such

[.,] means either a dot or a comma symbol

And you just need to concatenate the pieces together, so in the case where you want to represent a 1 or 2 digit number followed by either a comma or a period and followed by two more digits you would express it as follows: >

[0-9]{1,2}[.,]\d{1-2}

Also note that regular expression strings inside C++ strings must be double-back-slashed so every \ becomes \\

you can find Java compiler version from .class files using a Hex Editor.

Step 1: Extract .class files from jar file using a zip extractor

step 2: open .class file with a hex editor.(I have used notepad++ hex editor plugin. This plugin reads file as binary and shows it in hex) You can see below.

Index 6 and 7 gives major version number of the class file format being used. https://en.wikipedia.org/wiki/Java_class_file

Java SE 11 = 55 (0x37 hex)

Java SE 10 = 54 (0x36 hex)

Java SE 9 = 53 (0x35 hex)

Java SE 8 = 52 (0x34 hex),

Java SE 7 = 51 (0x33 hex),

Java SE 6.0 = 50 (0x32 hex),

Java SE 5.0 = 49 (0x31 hex),

JDK 1.4 = 48 (0x30 hex),

JDK 1.3 = 47 (0x2F hex),

JDK 1.2 = 46 (0x2E hex),

JDK 1.1 = 45 (0x2D hex).

can try this

select (CONVERT(VARCHAR(10),GETDATE()+360,110)) as Date_Result

To extend the answer a little bit to support local images, just replace FILE_PATH_PLACEHOLDER to your image path and check it out.

<p align="center">
  <img src="FILE_PATH_PLACEHOLDER">
</p>

If you set the text state, why not use that directly?

_handlePress(event) {
  var username=this.state.text;

Of course the variable naming could be more descriptive than 'text' but your call.

PIL (Python Imaging Library) and Numpy work well together.

I use the following functions.

from PIL import Image
import numpy as np

def load_image( infilename ) :
    img = Image.open( infilename )
    img.load()
    data = np.asarray( img, dtype="int32" )
    return data

def save_image( npdata, outfilename ) :
    img = Image.fromarray( np.asarray( np.clip(npdata,0,255), dtype="uint8"), "L" )
    img.save( outfilename )

The 'Image.fromarray' is a little ugly because I clip incoming data to [0,255], convert to bytes, then create a grayscale image. I mostly work in gray.

An RGB image would be something like:

 outimg = Image.fromarray( ycc_uint8, "RGB" )
 outimg.save( "ycc.tif" )

The shortest way (will print "not same" because String comparison is case sensitive):

def compareString = {
   it == "india" ? "same" : "not same"
}    

compareString("India")

When you call "https://darkorbit.com/" your server figures that it's missing "www" so it redirects the call to "http://www.darkorbit.com/" and then to "https://www.darkorbit.com/", your WebView call is blocked at the first redirection as it's a "http" call. You can call "https://www.darkorbit.com/" instead and it will solve the issue.

Ref: Apache redirect www to non-www and HTTP to HTTPS

http://example.com

http://www.example.com

https://www.example.com

to

https://example.com

RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [L,NE,R=301]

If instead of example.com you want the default URL to be www.example.com, then simply change the third and the fifth lines:

RewriteEngine On
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^ https://www.%1%{REQUEST_URI} [L,NE,R=301]

I was trying to do the same thing, but I wanted the back button to be in the navigation bar. (I actually needed a back button, that would do more than only going back, so I had to use the leftBarButtonItem property). I tried what AndrewS suggested, but in the navigation bar it wouldn't look the way it should, as the UIButton was kind of casted to a UIBarButtonItem.

But I found a way to work around this. I actually just put a UIView under the UIButton and set the customView for the UIBarButtonItem. Here is the code, if somebody needs it:

// initialize button and button view
UIButton *backButton = [UIButton buttonWithType:101];
UIView *backButtonView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, backButton.frame.size.width, backButton.frame.size.height)];

[backButton addTarget:self action:@selector(backButtonTouched:) forControlEvents:UIControlEventTouchUpInside];
[backButton setTitle:@"Back" forState:UIControlStateNormal];
[backButtonView addSubview:backButton];

// set buttonview as custom view for bar button item
UIBarButtonItem *backButtonItem = [[UIBarButtonItem alloc] initWithCustomView:backButtonView];
self.navigationItem.leftBarButtonItem = backButtonItem;

// push item to navigationbar items
[self.navigationController.navigationBar setItems:[NSArray arrayWithObject:backButtonItem]];

public static void main(String[] args) {

    List<String> ls=new ArrayList<String>();
    ls.add("1");
    ls.add("2");
    ls.add("3");
    ls.add("4");

//Then  you can use "foreache" loop to iterate.

    for(String item:ls){
        System.out.println(item);
    }

}

trying the CreativeMagic solution, the credential problem is confirmed:

prompt>>>Username for 'https://github.com'

So, I changed my origin url with

git remote set-url --add origin http://github.com/user/repo

and

git push --set-upstream origin master

This fix / solution worked for me: Device Manager --> Ports --> right click on Arduino Uno --> Update Driver Software --> Search automatically for updated driver software

Your adb connection is broken.

close eclipse

open cmd-prompt type adb kill-server then adb start-server

reopen eclipse

run the project!

1) on your mac type

nano /usr/bin/wget

2) paste the following in

#!/bin/bash
curl -L $1 -o $2

3) close then make it executable

chmod 777 /usr/bin/wget

That's it.

I tested and used this command in kafka confluent V4.0.0 and apache kafka V 1.0.0 and 1.0.1

/opt/kafka/confluent-4.0.0/bin/kafka-configs --zookeeper XX.XX.XX.XX:2181 --entity-type topics --entity-name test --alter --add-config  retention.ms=55000

test is the topic name.

I think it works well in other versions too

When an instance of java.util.Random is constructed with a specific seed parameter (in this case -229985452 or -147909649), it follows the random number generation algorithm beginning with that seed value.

Every Random constructed with the same seed will generate the same pattern of numbers every time.

setting direction CSS property to rtl should work with you. I guess it isn't supported on IE6.

e.g

<ul style="direction:rtl;">
<li> item </li>
<li> item </li>
</ul>

Well, as Trufa has already shown, there are basically two ways of replacing a tuple's element at a given index. Either convert the tuple to a list, replace the element and convert back, or construct a new tuple by concatenation.

In [1]: def replace_at_index1(tup, ix, val):
   ...:     lst = list(tup)
   ...:     lst[ix] = val
   ...:     return tuple(lst)
   ...:

In [2]: def replace_at_index2(tup, ix, val):
   ...:     return tup[:ix] + (val,) + tup[ix+1:]
   ...:

So, which method is better, that is, faster?

It turns out that for short tuples (on Python 3.3), concatenation is actually faster!

In [3]: d = tuple(range(10))

In [4]: %timeit replace_at_index1(d, 5, 99)
1000000 loops, best of 3: 872 ns per loop

In [5]: %timeit replace_at_index2(d, 5, 99)
1000000 loops, best of 3: 642 ns per loop

Yet if we look at longer tuples, list conversion is the way to go:

In [6]: k = tuple(range(1000))

In [7]: %timeit replace_at_index1(k, 500, 99)
100000 loops, best of 3: 9.08 µs per loop

In [8]: %timeit replace_at_index2(k, 500, 99)
100000 loops, best of 3: 10.1 µs per loop

For very long tuples, list conversion is substantially better!

In [9]: m = tuple(range(1000000))

In [10]: %timeit replace_at_index1(m, 500000, 99)
10 loops, best of 3: 26.6 ms per loop

In [11]: %timeit replace_at_index2(m, 500000, 99)
10 loops, best of 3: 35.9 ms per loop

Also, performance of the concatenation method depends on the index at which we replace the element. For the list method, the index is irrelevant.

In [12]: %timeit replace_at_index1(m, 900000, 99)
10 loops, best of 3: 26.6 ms per loop

In [13]: %timeit replace_at_index2(m, 900000, 99)
10 loops, best of 3: 49.2 ms per loop

So: If your tuple is short, slice and concatenate. If it's long, do the list conversion!

import urllib

def connected(host='http://google.com'):
    try:
        urllib.urlopen(host)
        return True
    except:
        return False

# test
print( 'connected' if connected() else 'no internet!' )

For python 3, use urllib.request.urlopen(host)

Use, CollectionUtils.isEmpty(Collection coll) method which is Null-safe check if the specified collection is empty.

for this import org.apache.commons.collections.CollectionUtils.

With ES6 and later (ECMAScript 2015), you can get all properties like this:

let keys = Object.keys(myObject);

And if you wanna list out all values:

let values = Object.keys(myObject).map(key => myObject[key]);

There are several ways to convert SVG to PNG using the Canvg library.

In my case, I needed to get the PNG blob from inline SVG.

The library documentation provides an example (see OffscreenCanvas example).

But this method does not work at the moment in Firefox. Yes, you can enable the gfx.offscreencanvas.enabled option in the settings. But will every user on the site do this? :)

However, there is another way that will work in Firefox too.

const el = document.getElementById("some-svg"); //this is our inline SVG

var canvas = document.createElement('canvas'); //create a canvas for the SVG render
canvas.width = el.clientWidth; //set canvas sizes
canvas.height = el.clientHeight;

const svg = new XMLSerializer().serializeToString(el); //convert SVG to string

//render SVG inside canvas
const ctx = canvas.getContext('2d');
const v = await Canvg.fromString(ctx, svg);
await v.render();

let canvasBlob = await new Promise(resolve => canvas.toBlob(resolve));

For the last line thanks to this answer

Standardize your module's imports and exports then you won't risk hitting problems with misspelled property names.

module.exports = Component should become export default Component.

CommonJS uses module.exports as a convention, however, this means that you are just working with a regular Javascript object and you are able to set the value of any key you want (whether that's exports, exoprts or exprots). There are no runtime or compile-time checks to tell you that you've messed up.

If you use ES6 (ES2015) syntax instead, then you are working with syntax and keywords. If you accidentally type exoprt default Component then it will give you a compile error to let you know.

In your case, you can simplify the Speaker component.

import React from 'react';

export default React.createClass({
  render() {
    return (
      <h1>Speaker</h1>
    )
  }
});

For What its worth, this is what I did and maybe it can help others even though the article is old.

PHP:

session_start();

$_SESSION['ipaddress'] = $_SERVER['REMOTE_ADDR'];

if(isset($_SESSION['userID'])){
    if(!strpos($_SESSION['activeID'], '-')){
        $_SESSION['activeID'] = $_SESSION['userID'].'-'.$_SESSION['activeID'];
    }
}elseif(!isset($_SESSION['activeID'])){
    $_SESSION['activeID'] = time();
}

JS

window.setInterval(function(){
            var userid = '<?php echo $_SESSION['activeID']; ?>';
            var ipaddress = '<?php echo $_SESSION['ipaddress']; ?>';
            var action = 'data';

            $.ajax({
                url:'activeUser.php',
                method:'POST',
                data:{action:action,userid:userid,ipaddress:ipaddress},
                success:function(response){
                     //alert(response);                 
                }
            });
          }, 5000);

Ajax call to activeUser.php

if(isset($_POST['action'])){
    if(isset($_POST['userid'])){
        $stamp = time();
        $activeid = $_POST['userid'];
        $ip = $_POST['ipaddress'];

        $query = "SELECT stamp FROM activeusers WHERE activeid = '".$activeid."' LIMIT 1";
        $results = RUNSIMPLEDB($query);

        if($results->num_rows > 0){
            $query = "UPDATE activeusers SET stamp = '$stamp' WHERE activeid = '".$activeid."' AND ip = '$ip' LIMIT 1";
            RUNSIMPLEDB($query);
        }else{
            $query = "INSERT INTO activeusers (activeid,stamp,ip)
                    VALUES ('".$activeid."','$stamp','$ip')";
            RUNSIMPLEDB($query);
        }
    }
}

Database:

CREATE TABLE `activeusers` (
  `id` int(11) NOT NULL,
  `activeid` varchar(20) NOT NULL,
  `stamp` int(11) NOT NULL,
  `ip` text
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

Basically every 5 seconds the js will post to a php file that will track the user and the users ip address. Active users are simply a database record that have an update to the database time stamp within 5 seconds. Old users stop updating to the database. The ip address is used just to ensure that a user is unique so 2 people on the site at the same time don't register as 1 user.

Probably not the most efficient solution but it does the job.

Thank you so much for this. I have modified it to work with Windows. I have also put a low timeout so, the IP's that have no return will not sit and wait for 5 seconds each. This is from hochl source code.

import subprocess
import os
with open(os.devnull, "wb") as limbo:
        for n in xrange(200, 240):
                ip="10.2.7.{0}".format(n)
                result=subprocess.Popen(["ping", "-n", "1", "-w", "200", ip],
                        stdout=limbo, stderr=limbo).wait()
                if result:
                        print ip, "inactive"
                else:
                        print ip, "active"

Just change the ip= for your scheme and the xrange for the hosts.

shouldn't the button be 100% width if it's "display: block"

No. That just means it's the only thing in the space vertically (assuming you aren't using another trick to force something else there as well). It doesn't mean it has to fill up the width of that space.

I think your problem in this instance is that the input is not natively a block element. Try nesting it inside another div and set the margin on that. But I don't have an IE8 browser to test this with at the moment, so it's just a guess.

Adding on to the other answers using requests:

 # download from web

 import requests
 url = 'http://mlg.ucd.ie/files/datasets/bbc.zip'
 content = requests.get(url)

 # unzip the content
 from io import BytesIO
 from zipfile import ZipFile
 f = ZipFile(BytesIO(content.content))
 print(f.namelist())

 # outputs ['bbc.classes', 'bbc.docs', 'bbc.mtx', 'bbc.terms']

Use help(f) to get more functions details for e.g. extractall() which extracts the contents in zip file which later can be used with with open.

I don't mention basics like syntax highlighting as I expect these by default.

This is a just dry list reflecting your feedback and comments, I am not advocating any of these tools. I will keep updating this list as you keep posting your answers.

PS. Can you help me to add features of the above editors to the list (like auto-complete, debugging, etc.)?

We have a comprehensive wiki page for this question https://wiki.python.org/moin/IntegratedDevelopmentEnvironments

It's not a cut and paste. The CASE expression must return a value, and you are returning a string containing SQL (which is technically a value but of a wrong type). This is what you wanted to write, I think:

SELECT * FROM [Purchasing].[Vendor] WHERE  
CASE
  WHEN @url IS null OR @url = '' OR @url = 'ALL'
    THEN PurchasingWebServiceURL LIKE '%'
  WHEN @url = 'blank'
    THEN PurchasingWebServiceURL = ''
  WHEN @url = 'fail'
    THEN PurchasingWebServiceURL NOT LIKE '%treyresearch%'
  ELSE PurchasingWebServiceURL = '%' + @url + '%' 
END

I also suspect that this might not work in some dialects, but can't test now (Oracle, I'm looking at you), due to not having booleans.

However, since @url is not dependent on the table values, why not make three different queries, and choose which to evaluate based on your parameter?

Make sure you include http://code.angularjs.org/1.0.0rc10/angular-cookies-1.0.0rc10.js to use it.

You can do something like this,

  Dim lstOfStrings As New List(Of String) From {"Value1", "Value2", "Value3"}

Generally, Threads are called light weight process. If we divide memory into three sections then it will be: Code, data and Stack. Every process has its own code, data and stack sections and due to this context switch time is a little high. To reduce context switching time, people have come up with concept of thread, which shares Data and code segment with other thread/process and it has its own STACK segment.

In appdelegate.m file write the follwing code in applicationDidEnterBackground to get the local notification

- (void)applicationDidEnterBackground:(UIApplication *)application
{
   UILocalNotification *notification = [[UILocalNotification alloc]init];
   notification.repeatInterval = NSDayCalendarUnit;
   [notification setAlertBody:@"Hello world"];
   [notification setFireDate:[NSDate dateWithTimeIntervalSinceNow:1]];
   [notification setTimeZone:[NSTimeZone  defaultTimeZone]];
   [application setScheduledLocalNotifications:[NSArray arrayWithObject:notification]];
}

Just call the modal method(without passing any parameters) using jQuery selector.

Here is example:

$('#modal').modal();

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

Take a look at the formats in ?strptime

R> foo <-  factor("1/15/2006 0:00:00")
R> foo <- as.Date(foo, format = "%m/%d/%Y %H:%M:%S")                                           
R> foo                                                                                       
 [1] "2006-01-15"                                                                             
R> class(foo)                                                                                
 [1] "Date"  

Note that this will work even if foo starts out as a character. It will also work if using other date formats (as.POSIXlt, as.POSIXct).

There was a relevant answer from Ask Tom published in April 2016.

If you have sufficient server power, you can do

select /*+ parallel */ count(*) from sometable

If you are just after an approximation, you can do :

select 5 * count(*) from sometable sample block (10);

Also, if there is

1. a column that contains no nulls, but is not defined as NOT NULL, and
2. there is an index on that column

you could try:

select /*+ index_ffs(t) */ count(*) from sometable  t where indexed_col is not null

It should be noted that the documentation recommends using a Layout rather than Canvas.drawText directly. My full answer about using a StaticLayout is here, but I will provide a summary below.

String text = "This is some text.";

TextPaint textPaint = new TextPaint();
textPaint.setAntiAlias(true);
textPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
textPaint.setColor(0xFF000000);

int width = (int) textPaint.measureText(text);
StaticLayout staticLayout = new StaticLayout(text, textPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
staticLayout.draw(canvas);

Here is a fuller example in the context of a custom view:

public class MyView extends View {

    String mText = "This is some text.";
    TextPaint mTextPaint;
    StaticLayout mStaticLayout;

    // use this constructor if creating MyView programmatically
    public MyView(Context context) {
        super(context);
        initLabelView();
    }

    // this constructor is used when created from xml
    public MyView(Context context, AttributeSet attrs) {
        super(context, attrs);
        initLabelView();
    }

    private void initLabelView() {
        mTextPaint = new TextPaint();
        mTextPaint.setAntiAlias(true);
        mTextPaint.setTextSize(16 * getResources().getDisplayMetrics().density);
        mTextPaint.setColor(0xFF000000);

        // default to a single line of text
        int width = (int) mTextPaint.measureText(mText);
        mStaticLayout = new StaticLayout(mText, mTextPaint, (int) width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);

        // New API alternate
        //
        // StaticLayout.Builder builder = StaticLayout.Builder.obtain(mText, 0, mText.length(), mTextPaint, width)
        //        .setAlignment(Layout.Alignment.ALIGN_NORMAL)
        //        .setLineSpacing(1, 0) // multiplier, add
        //        .setIncludePad(false);
        // mStaticLayout = builder.build();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        // Tell the parent layout how big this view would like to be
        // but still respect any requirements (measure specs) that are passed down.

        // determine the width
        int width;
        int widthMode = MeasureSpec.getMode(widthMeasureSpec);
        int widthRequirement = MeasureSpec.getSize(widthMeasureSpec);
        if (widthMode == MeasureSpec.EXACTLY) {
            width = widthRequirement;
        } else {
            width = mStaticLayout.getWidth() + getPaddingLeft() + getPaddingRight();
            if (widthMode == MeasureSpec.AT_MOST) {
                if (width > widthRequirement) {
                    width = widthRequirement;
                    // too long for a single line so relayout as multiline
                    mStaticLayout = new StaticLayout(mText, mTextPaint, width, Layout.Alignment.ALIGN_NORMAL, 1.0f, 0, false);
                }
            }
        }

        // determine the height
        int height;
        int heightMode = MeasureSpec.getMode(heightMeasureSpec);
        int heightRequirement = MeasureSpec.getSize(heightMeasureSpec);
        if (heightMode == MeasureSpec.EXACTLY) {
            height = heightRequirement;
        } else {
            height = mStaticLayout.getHeight() + getPaddingTop() + getPaddingBottom();
            if (heightMode == MeasureSpec.AT_MOST) {
                height = Math.min(height, heightRequirement);
            }
        }

        // Required call: set width and height
        setMeasuredDimension(width, height);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        super.onDraw(canvas);
        // do as little as possible inside onDraw to improve performance

        // draw the text on the canvas after adjusting for padding
        canvas.save();
        canvas.translate(getPaddingLeft(), getPaddingTop());
        mStaticLayout.draw(canvas);
        canvas.restore();
    }
}

Other solutions on this page aren't desirable if you have a long list of extensions -- maintaining a long sequence of -not -name 'this' -not -name 'that' -not -name 'other' would be tedious and error-prone -- or if the search is programmatic and the list of extensions is built at runtime.

For those situations, a solution that more clearly separates data (the list of extensions) and code (the parameters to find) may be desirable. Given a directory & file structure that looks like this:

.
+-- a
    +-- 1.txt
    +-- 15.xml
    +-- 8.dll
    +-- b
    ¦   +-- 16.xml
    ¦   +-- 2.txt
    ¦   +-- 9.dll
    ¦   +-- c
    ¦       +-- 10.dll
    ¦       +-- 17.xml
    ¦       +-- 3.txt
    +-- d
    ¦   +-- 11.dll
    ¦   +-- 18.xml
    ¦   +-- 4.txt
    ¦   +-- e
    ¦       +-- 12.dll
    ¦       +-- 19.xml
    ¦       +-- 5.txt
    +-- f
        +-- 13.dll
        +-- 20.xml
        +-- 6.txt
        +-- g
            +-- 14.dll
            +-- 21.xml
            +-- 7.txt

You can do something like this:

## data section, list undesired extensions here
declare -a _BADEXT=(xml dll)

## code section, this never changes
BADEXT="$( IFS="|" ; echo "${_BADEXT[*]}" | sed 's/|/\\|/g' )"
find . -type f ! -regex ".*\.\($BADEXT\)"

Which results in:

./a/1.txt
./a/b/2.txt
./a/b/c/3.txt
./a/d/4.txt
./a/d/e/5.txt
./a/f/6.txt
./a/f/g/7.txt

You can change the extensions list without changing the code block.

NOTE doesn't work with native OSX find - use gnu find instead.

Your problem is really common. See "Using Mailmap to Fix Authors List in Git"

For the sake of simplicity, I have created a script to ease the process: git-changemail

After putting that script on your path, you can issue commands like:

• Change author matchings on current branch

  $ git changemail -a [email protected] -n newname -m [email protected]
  

• Change author and committer matchings on <branch> and <branch4>. Pass -f to filter-branch to allow rewriting backups

  $ git changemail -b [email protected] -n newname -m [email protected] -- -f <branch> <branch2>
  

• Show existing users on repo

  $ git changemail --show-both
  

By the way, after making your changes, clean the backup from the filter-branch with: git-backup-clean

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

most convinient way on my own:

LINE_COUNT = 3
print [s for (i, s) in enumerate(open('test.txt')) if i < LINE_COUNT]

Solution based on List Comprehension The function open() supports an iteration interface. The enumerate() covers open() and return tuples (index, item), then we check that we're inside an accepted range (if i < LINE_COUNT) and then simply print the result.

Enjoy the Python. ;)

I think the problem is not in sub-query but in WHERE clause of outer query. When you use

WHERE account_code between 503100 and 503105

SQL server will try to convert every value in your Account_code field to integer to test it in provided condition. Obviously it will fail to do so if there will be non-integer characters in some rows.

Make sure the hamcrest jar is higher on the import order than your JUnit jar.

JUnit comes with its own org.hamcrest.Matcher class that is probably being used instead.

You can also download and use the junit-dep-4.10.jar instead which is JUnit without the hamcrest classes.

mockito also has the hamcrest classes in it as well, so you may need to move\reorder it as well

Sequel (Ruby ORM) has a command line tool for dealing with databases, you must have ruby installed, then:

  $ gem install sequel mysql2 sqlite3 
  $ sequel mysql2://user:password@host/database -C sqlite://db.sqlite

Russian Edition offers CSV, CSV (Macintosh) and CSV (DOS).

When saving in plain CSV, it uses windows-1251.

I just tried to save French word Résumé along with the Russian text, it saved it in HEX like 52 3F 73 75 6D 3F, 3F being the ASCII code for question mark.

When I opened the CSV file, the word, of course, became unreadable (R?sum?)

Take a look at ?legend and try this:

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

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

Use a terminal-handling library like the curses module:

The curses module provides an interface to the curses library, the de-facto standard for portable advanced terminal handling.

This is what i have done to get rid of this error separating variable with "," helped me.

# Applying BODMAS

Do something like this:

<script>
function changeColor(id)
{
  document.getElementById(id).style.color = "#ff0000"; // forecolor
  document.getElementById(id).style.backgroundColor = "#ff0000"; // backcolor
}
</script>

<div id="myid">Hello There !!</div>

<a href="#" onclick="changeColor('myid'); return false;">Change Color</a>

In a corporate network, where the user has only limited access and uses portable apps, there are these command line tricks:

1. Query the user env variables: reg query "HKEY_CURRENT_USER\Environment". Use "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" for LOCAL_MACHINE.
2. Add new user env variable: reg add "HKEY_CURRENT_USER\Environment" /v shared_dir /d "c:\shared" /t REG_SZ. Use REG_EXPAND_SZ for paths containing other %% variables.
3. Delete existing env variable: reg delete "HKEY_CURRENT_USER\Environment" /v shared_dir.

Use -C option of tar:

tar zxvf <yourfile>.tar.gz -C /usr/src/

and then, the content of the tar should be in:

/usr/src/<yourfile>

Unfortunately this was a limitation of Firebase Notifications in SDK 9.0.0-9.6.1. When the app is in the background the launcher icon is use from the manifest (with the requisite Android tinting) for messages sent from the console.

With SDK 9.8.0 however, you can override the default! In your AndroidManifest.xml you can set the following fields to customise the icon and color:

<meta-data
        android:name="com.google.firebase.messaging.default_notification_icon"
        android:resource="@drawable/notification_icon" />
<meta-data android:name="com.google.firebase.messaging.default_notification_color"
        android:resource="@color/google_blue" />

Note that if the app is in the foreground (or a data message is sent) you can completely use your own logic to customise the display. You can also always customise the icon if sending the message from the HTTP/XMPP APIs.

I can confirm that mp4 just will not work in the video tag. No matter how much you try to mess with the type tag and the codec and the mime types from the server.

Crazy, because for the same exact video, on the same test page, the old embed tag for an mp4 works just fine in firefox. I spent all yesterday messing with this. Firefox is like IE all of a sudden, hours and hours of time, not billable. Yay.

Speaking of IE, it fails FAR MORE gracefully on this. When it can't match up the format it falls to the content between the tags, so it is possible to just put video around object around embed and everything works great. Firefox, nope, despite failing, it puts up the poster image (greyed out so that isn't even useful as a fallback) with an error message smack in the middle. So now the options are put in browser recognition code (meaning we've gained nothing on embedding videos in the last ten years) or ditch html5.

could you please try below code

<c:forEach var="hash" items="${map['key']}">
        <option><c:out value="${hash}"/></option>
  </c:forEach>

You can try implicit wait:

WebDriver driver = new FirefoxDriver();
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
driver.Url = "http://somedomain/url_that_delays_loading";
IWebElement myDynamicElement = driver.FindElement(By.Id("someDynamicElement"));

Or You can try explicit wait one:

IWebDriver driver = new FirefoxDriver();
driver.Url = "http://somedomain/url_that_delays_loading";
WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromSeconds(10));
IWebElement myDynamicElement = wait.Until<IWebElement>((d) =>
    {
        return d.FindElement(By.Id("someDynamicElement"));
    });

Explicit will check if element is present before some action. Implicit wait could be call in every place in the code. For example after some AJAX actions.

You can't decrypt password in mysql, because password is hashed by using md5 hash algorithm, which is not an encoding algorithm.

while(!feof(fp))
{
  ch = fgetc(fp);
  if(ch == '\n')

But please note: Why is “while ( !feof (file) )” always wrong?.

I've created this function to clean up a string that contained non numeric characters in a time field. The time contained question marks when they did not added the minutes, something like this 20:??. Function loops through each character and replaces the ? with a 0 :

 CREATE FUNCTION [dbo].[CleanTime]
(
    -- Add the parameters for the function here
    @intime nvarchar(10) 
)
RETURNS nvarchar(5)
AS
BEGIN
    -- Declare the return variable here
    DECLARE @ResultVar nvarchar(5)
    DECLARE @char char(1)
    -- Add the T-SQL statements to compute the return value here
    DECLARE @i int = 1
    WHILE @i <= LEN(@intime)
    BEGIN
    SELECT @char =  CASE WHEN substring(@intime,@i,1) like '%[0-9:]%' THEN substring(@intime,@i,1) ELSE '0' END
    SELECT @ResultVar = concat(@ResultVar,@char)   
    set @i  = @i + 1       
    END;
    -- Return the result of the function
    RETURN @ResultVar

END

I wanted a more exact and useful answer to this question. Here's the real answer (adjust accordingly if you want a byte array specifically; obviously the math will be off by a factor of 8 bits : 1 byte):

class BitArray {
  constructor(bits = 0) {
    this.uints = new Uint32Array(~~(bits / 32));
  }

  getBit(bit) {
    return (this.uints[~~(bit / 32)] & (1 << (bit % 32))) != 0 ? 1 : 0;
  }

  assignBit(bit, value) {
    if (value) {
      this.uints[~~(bit / 32)] |= (1 << (bit % 32));
    } else {
      this.uints[~~(bit / 32)] &= ~(1 << (bit % 32));
    }
  }

  get size() {
    return this.uints.length * 32;
  }

  static bitsToUints(bits) {
    return ~~(bits / 32);
  }
}

Usage:

let bits = new BitArray(500);
for (let uint = 0; uint < bits.uints.length; ++uint) {
  bits.uints[uint] = 457345834;
}
for (let bit = 0; bit < 50; ++bit) {
  bits.assignBit(bit, 1);
}
str = '';
for (let bit = bits.size - 1; bit >= 0; --bit) {
  str += bits.getBit(bit);
}
str;

Output:

"00011011010000101000101100101010
 00011011010000101000101100101010

 11111111111111111111111111111111"

Note: This class is really slow to e.g. assign bits (i.e. ~2s per 10 million assignments) if it's created as a global variable, at least in the Firefox 76.0 Console on Linux... If, on the other hand, it's created as a variable (i.e. let bits = new BitArray(1e7);), then it's blazingly fast (i.e. ~300ms per 10 million assignments)!

For more info, see here:

• "How do you set, clear and toggle a single bit in JavaScript?": https://stackoverflow.com/a/1436448/1599699

• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Typed_arrays
• https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Uint32Array

Note that I used Uint32Array because there's no way to directly have a bit/byte array (that you can interact with directly) and because even though there's a BigUint64Array, JS only supports 32 bits:

Bitwise operators treat their operands as a sequence of 32 bits

...

The operands of all bitwise operators are converted to...32-bit integers

Use Z-index to move the one you want on top.

If you use copy-on-write collections it will work; however when you use list.iterator(), the returned Iterator will always reference the collection of elements as it was when ( as below ) list.iterator() was called, even if another thread modifies the collection. Any mutating methods called on a copy-on-write–based Iterator or ListIterator (such as add, set, or remove) will throw an UnsupportedOperationException.

import java.util.List;
import java.util.concurrent.CopyOnWriteArrayList;

public class RemoveListElementDemo {    
    private static final List<Integer> integerList;

    static {
        integerList = new CopyOnWriteArrayList<>();
        integerList.add(1);
        integerList.add(2);
        integerList.add(3);
    }

    public static void remove(Integer remove) {
        for(Integer integer : integerList) {
            if(integer.equals(remove)) {                
                integerList.remove(integer);
            }
        }
    }

    public static void main(String... args) {                
        remove(Integer.valueOf(2));

        Integer remove = Integer.valueOf(3);
        for(Integer integer : integerList) {
            if(integer.equals(remove)) {                
                integerList.remove(integer);
            }
        }
    }
}

I would use the second method as it is more explicit. Otherwise you don't know where the variables are coming from.

Why do you need to check both GET and POST anyway? Surely using one or the other only makes more sense.

You are checking it the array index contains a string "undefined", you should either use the typeof operator:

typeof predQuery[preId] == 'undefined'

Or use the undefined global property:

predQuery[preId] === undefined

The first way is safer, because the undefined global property is writable, and it can be changed to any other value.

Byterbit solution is problematic because:

1. having the client control expiration of a server side cookie is a security issue.
2. if expiration timeout set on server side is smaller than the timeout set on client side, the page would not reflect the actual state of the cookie.
3. even if for the sake of comfort in development stage, this is a problem because it won't reflect the right behaviour (in timing) on release stage.

for cookies, setting expiration via session.cookie_lifetime is the right solution design-wise and security-wise! for expiring the session, you can use session.gc_maxlifetime.

expiring the cookies by calling session_destroy might yield unpredictable results because they might have already been expired.

making the change in php.ini is also a valid solution but it makes the expiration global for the entire domain which might not be what you really want - some pages might choose to keep some cookies more than others.

To set custom headers ON A REQUEST, build a request with the custom header before passing it to httpclient to send to http server. eg:

HttpClient client = HttpClients.custom().build();
HttpUriRequest request = RequestBuilder.get()
  .setUri(someURL)
  .setHeader(HttpHeaders.CONTENT_TYPE, "application/json")
  .build();
client.execute(request);

Default header is SET ON HTTPCLIENT to send on every request to the server.

Here's a UIButton subclass that supports the highlighted state animation without using images. It also updates the border color when the view's tint mode changes.

class BorderedButton: UIButton {
    override init(frame: CGRect) {
        super.init(frame: frame)

        layer.borderColor = tintColor.CGColor
        layer.borderWidth = 1
        layer.cornerRadius = 5

        contentEdgeInsets = UIEdgeInsets(top: 5, left: 10, bottom: 5, right: 10)
    }

    required init?(coder aDecoder: NSCoder) {
        fatalError("NSCoding not supported")
    }

    override func tintColorDidChange() {
        super.tintColorDidChange()

        layer.borderColor = tintColor.CGColor
    }

    override var highlighted: Bool {
        didSet {
            let fadedColor = tintColor.colorWithAlphaComponent(0.2).CGColor

            if highlighted {
                layer.borderColor = fadedColor
            } else {
                layer.borderColor = tintColor.CGColor

                let animation = CABasicAnimation(keyPath: "borderColor")
                animation.fromValue = fadedColor
                animation.toValue = tintColor.CGColor
                animation.duration = 0.4
                layer.addAnimation(animation, forKey: "")
            }
        }
    }
}

Usage:

let button = BorderedButton(style: .System) //style .System is important

Appearance:

$string="1,2,3,4,5";
$array=array_map('intval', explode(',', $string));
$array = implode("','",$array);
$query=mysqli_query($conn, "SELECT name FROM users WHERE id IN ('".$array."')");

NB: the syntax is:

SELECT * FROM table WHERE column IN('value1','value2','value3')

Javascript is single threaded, hence the page blocking behaviour. You can use the deferred/promise approach suggested by others, but the most basic way would be to use window.setTimeout. E.g.

function checkFlag() {
    if(flag == false) {
       window.setTimeout(checkFlag, 100); /* this checks the flag every 100 milliseconds*/
    } else {
      /* do something*/
    }
}
checkFlag();

Here is a good tutorial with further explanation: Tutorial

EDIT

As others pointed out, the best way would be to re-structure your code to use callbacks. However, this answer should give you an idea how you can 'simulate' an asynchronous behaviour with window.setTimeout.

Use the os.path module.

os.path.join( "C:", "meshes", "as" )

Or use raw strings

r"C:\meshes\as"

I would also recommend no spaces in the path or file names. And you could use double backslashes in your strings.

"C:\\meshes\\as.jpg"

use parse_url and then output the result in a loop:

$urlinfo = parse_url($the_url);
echo makelink($urlinfo['hostname']);
foreach($breadcrumb in $urlinfo['path']) {
  echo makelink($breadcrumb);
}

function makelink($str) {
  return '<a href="'.urlencode($str).'" title="'.htmlspecialchars($str).'">'.htmlspecialchars($str).'</a>';
}

(pseudocode)

Just use:

 param.AddWithValue("@Date_Of_Birth",DOB);

That will take care of all your problems.

remember, SSL/TLS operates at the Transport Layer, so all the crypto goo happens under the application-layer HTTP stuff.

http://en.wikipedia.org/wiki/File:IP_stack_connections.svg

that's the long way of saying, "Yes!"

If you are using Chrome you can goto the "Resources" tab and find the item "Cookies" in the left sidebar. From there select the domain you are checking the set cookie for and it will give you a list of cookies associated with that domain, along with their expiration date.

If i understood correct try this one

$headers = "Bcc: [email protected]";

or

$headers = "Cc: [email protected]";

Because the purpose of an interface is to allow polymorphism, being able to pass an instance of any number of defined classes that have all been defined to implement the defined interface... guaranteeing that within your polymorphic call, the code will be able to find the method you are calling. it makes no sense to allow a static method to implement the interface,

How would you call it??

public interface MyInterface { void MyMethod(); }
public class MyClass: MyInterface
{
    public static void MyMethod() { //Do Something; }
}

 // inside of some other class ...  
 // How would you call the method on the interface ???
    MyClass.MyMethod();  // this calls the method normally 
                         // not through the interface...

    // This next fails you can't cast a classname to a different type... 
    // Only instances can be Cast to a different type...
    MyInterface myItf = MyClass as MyInterface;  

Add dots after the second slice:

//---------------------------vvv
append([]int{1,2}, []int{3,4}...)

This is just like any other variadic function.

func foo(is ...int) {
    for i := 0; i < len(is); i++ {
        fmt.Println(is[i])
    }
}

func main() {
    foo([]int{9,8,7,6,5}...)
}

Actually, you have to explicitly compare it to true. If the dialog doesn't exist yet, it will not return false (as you would expect), it will return a DOM object.

if ($('#mydialog').dialog('isOpen') === true) {
    // true
} else {
    // false
}

• To list the Docker images

  $ docker images
  

• If your application wants to run in with port 80, and you can expose a different port to bind locally, say 8080:

  $ docker run -d --restart=always -p 8080:80 image_name:version
  

One possible solution is do the concatenation manually, here is some useful code:

import json
def append_to_json(_dict,path): 
    with open(path, 'ab+') as f:
        f.seek(0,2)                                #Go to the end of file    
        if f.tell() == 0 :                         #Check if file is empty
            f.write(json.dumps([_dict]).encode())  #If empty, write an array
        else :
            f.seek(-1,2)           
            f.truncate()                           #Remove the last character, open the array
            f.write(' , '.encode())                #Write the separator
            f.write(json.dumps(_dict).encode())    #Dump the dictionary
            f.write(']'.encode())                  #Close the array

You should be careful when editing the file outside the script not add any spacing at the end.

set is used to assign a reference to an object. The C equivalent would be

 int i;
int* ref_i;

i = 4; // Assigning a value (in VBA: i = 4)
ref_i = &i; //assigning a reference (in VBA: set ref_i = i)

Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). Here's a version that's just a teeny bit cleaned up and which prints "kyle boon" as the decoded string:

import java.security.MessageDigest;
import java.util.Arrays;

import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class TripleDESTest {

    public static void main(String[] args) throws Exception {

        String text = "kyle boon";

        byte[] codedtext = new TripleDESTest().encrypt(text);
        String decodedtext = new TripleDESTest().decrypt(codedtext);

        System.out.println(codedtext); // this is a byte array, you'll just see a reference to an array
        System.out.println(decodedtext); // This correctly shows "kyle boon"
    }

    public byte[] encrypt(String message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);

        final byte[] plainTextBytes = message.getBytes("utf-8");
        final byte[] cipherText = cipher.doFinal(plainTextBytes);
        // final String encodedCipherText = new sun.misc.BASE64Encoder()
        // .encode(cipherText);

        return cipherText;
    }

    public String decrypt(byte[] message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        decipher.init(Cipher.DECRYPT_MODE, key, iv);

        // final byte[] encData = new
        // sun.misc.BASE64Decoder().decodeBuffer(message);
        final byte[] plainText = decipher.doFinal(message);

        return new String(plainText, "UTF-8");
    }
}

If this class is only a utility class, you should make the class final and define a private constructor:

public final class FilePathHelper {

   private FilePathHelper() {
      //not called
   }
}

This prevents the default parameter-less constructor from being used elsewhere in your code. Additionally, you can make the class final, so that it can't be extended in subclasses, which is a best practice for utility classes. Since you declared only a private constructor, other classes wouldn't be able to extend it anyway, but it is still a best practice to mark the class as final.

What I have done with no memory leaks or lint warnings is to use @f.trajkovski's method, but instead of using MainActivity, use WeakReference<MainActivity> instead.

public class MainActivity extends AppCompatActivity {
public static WeakReference<MainActivity> weakActivity;
// etc..
 public static MainActivity getmInstanceActivity() {
    return weakActivity.get();
}
}

Then in MainActivity OnCreate()

weakActivity = new WeakReference<>(MainActivity.this);

Then in another class

MainActivity.getmInstanceActivity().yourMethod();

Works like a charm

— :: — :: \u2014

When representing the m-dash in a JavaScript text string for output to HTML, note that it will be represented by its unicode value. There are cases when ampersand characters ('&') will not be resolved—notably certain contexts within JSX. In this case, neither — nor — will work. Instead you need to use the Unicode escape sequence: \u2014.

For example, when implementing a render() method to output text from a JavaScript variable:

render() {
   let text='JSX transcoders will preserve the & character—to ' 
            + 'protect from possible script hacking and cross-site hacks.'
   return (
     <div>{text}</div>
   )
}

This will output:

<div>JSX transcoders will preserve the & character&mdash;to protect from possible script hacking and cross-site hacks.</div>

Instead of the &– prefixed representation, you should use \u2014:

let text='JSX transcoders will preserve the & character\u2014to …'

<!DOCTYPE html>
<html>
<head></head>
<body>
<div style=" background-color: #00000088"> Hi there </div>
<!-- #00 would be r, 00 would be g, 00 would be b, 88 would be a. -->
</body>
</html>

including 4 sets of numbers would make it rgba, not cmyk, but either way would work (rgba= 00000088, cmyk= 0%, 0%, 0%, 50%)

// offsetWidth includes width of scroll bar and clientWidth doesn't. As rule, it equals 14-18px. so:

 var scrollBarWidth = element.offsetWidth - element.clientWidth;

You can actually put anything inside a toolbar. See the below code.

<android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentStart="true"
        android:background="@color/colorPrimary">

</android.support.v7.widget.Toolbar>

Between the above toolbar tag you can put almost anything. That is the benefit of using a Toolbar.

var myDate = new Date(); // Set this to your date in whichever timezone.
var utcDate = myDate.toUTCString();

This is a common problem. Use this instead of getApplicationContext() That should solve your problem

This is a kotlin solution. Put this helper method in some kotlin file-

fun EditText.setupClearButtonWithAction() {

    addTextChangedListener(object : TextWatcher {
        override fun afterTextChanged(editable: Editable?) {
            val clearIcon = if (editable?.isNotEmpty() == true) R.drawable.ic_clear else 0
            setCompoundDrawablesWithIntrinsicBounds(0, 0, clearIcon, 0)
        }

        override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) = Unit
        override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) = Unit
    })

    setOnTouchListener(View.OnTouchListener { _, event ->
        if (event.action == MotionEvent.ACTION_UP) {
            if (event.rawX >= (this.right - this.compoundPaddingRight)) {
                this.setText("")
                return@OnTouchListener true
            }
        }
        return@OnTouchListener false
    })
}

And then use it as following in the onCreate method and you should be good to go-

yourEditText.setupClearButtonWithAction()

BTW, you have to add R.drawable.ic_clear or the clear icon at first. This one is from google- https://material.io/tools/icons/?icon=clear&style=baseline

SHTML is a file extension that lets the web server know the file should be processed as using Server Side Includes (SSI).

(HTML is...you know what it is, and DHTML is Microsoft's name for Javascript+HTML+CSS or something).

You can use SSI to include a common header and footer in your pages, so you don't have to repeat code as much. Changing one included file updates all of your pages at once. You just put it in your HTML page as per normal.

It's embedded in a standard XML comment, and looks like this:

<!--#include virtual="top.shtml" -->

It's been largely superseded by other mechanisms, such as PHP includes, but some hosting packages still support it and nothing else.

You can read more in this Wikipedia article.

I've used the implementation above and just now I came to know that it doesn't work on iPad running iOS 13. I had to add these lines before present() call in order to make it work

//avoiding to crash on iPad
if let popoverController = activityViewController.popoverPresentationController {
     popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
     popoverController.sourceView = self.view
     popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
}

That's how it works for me

func shareData(_ dataToShare: [Any]){

        let activityViewController = UIActivityViewController(activityItems: dataToShare, applicationActivities: nil)

        //exclude some activity types from the list (optional)
        //activityViewController.excludedActivityTypes = [
            //UIActivity.ActivityType.postToFacebook
        //]

        //avoiding to crash on iPad
        if let popoverController = activityViewController.popoverPresentationController {
            popoverController.sourceRect = CGRect(x: UIScreen.main.bounds.width / 2, y: UIScreen.main.bounds.height / 2, width: 0, height: 0)
            popoverController.sourceView = self.view
            popoverController.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
        }

        self.present(activityViewController, animated: true, completion: nil)
    }

Option 1: Put this in your procedure to print 'comment' to stdout when it runs.

SELECT 'Comment';

Option 2: Put this in your procedure to print a variable with it to stdout:

declare myvar INT default 0;
SET myvar = 5;
SELECT concat('myvar is ', myvar);

This prints myvar is 5 to stdout when the procedure runs.

Option 3, Create a table with one text column called tmptable, and push messages to it:

declare myvar INT default 0;
SET myvar = 5;
insert into tmptable select concat('myvar is ', myvar);

You could put the above in a stored procedure, so all you would have to write is this:

CALL log(concat('the value is', myvar));

Which saves a few keystrokes.

Option 4, Log messages to file

select "penguin" as log into outfile '/tmp/result.txt';

There is very heavy restrictions on this command. You can only write the outfile to areas on disk that give the 'others' group create and write permissions. It should work saving it out to /tmp directory.

Also once you write the outfile, you can't overwrite it. This is to prevent crackers from rooting your box just because they have SQL injected your website and can run arbitrary commands in MySQL.

It looks like you want to define Truck as a Class with properties NumberOfAxles, AxleWeights & AxleSpacings.

This can be defined in a CLASS MODULE (here named clsTrucks)

Option Explicit

Private tID As String
Private tNumberOfAxles As Double
Private tAxleSpacings As Double


Public Property Get truckID() As String
    truckID = tID
End Property

Public Property Let truckID(value As String)
    tID = value
End Property

Public Property Get truckNumberOfAxles() As Double
    truckNumberOfAxles = tNumberOfAxles
End Property

Public Property Let truckNumberOfAxles(value As Double)
    tNumberOfAxles = value
End Property

Public Property Get truckAxleSpacings() As Double
    truckAxleSpacings = tAxleSpacings
End Property

Public Property Let truckAxleSpacings(value As Double)
    tAxleSpacings = value
End Property

then in a MODULE the following defines a new truck and it's properties and adds it to a collection of trucks and then retrieves the collection.

Option Explicit

Public TruckCollection As New Collection

Sub DefineNewTruck()
Dim tempTruck As clsTrucks
Dim i As Long

    'Add 5 trucks
    For i = 1 To 5
        Set tempTruck = New clsTrucks
        'Random data
        tempTruck.truckID = "Truck" & i
        tempTruck.truckAxleSpacings = 13.5 + i
        tempTruck.truckNumberOfAxles = 20.5 + i

        'tempTruck.truckID is the collection key
        TruckCollection.Add tempTruck, tempTruck.truckID
    Next i

    'retrieve 5 trucks
    For i = 1 To 5
        'retrieve by collection index
        Debug.Print TruckCollection(i).truckAxleSpacings
        'retrieve by key
        Debug.Print TruckCollection("Truck" & i).truckAxleSpacings

    Next i

End Sub

There are several ways of doing this so it really depends on how you intend to use the data as to whether an a class/collection is the best setup or arrays/dictionaries etc.

I had to replace spaces with plus symbols str_replace(' ', '+', $img); to get this working.

Here is the full code

$img = $_POST['img']; // Your data 'data:image/png;base64,AAAFBfj42Pj4';
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
file_put_contents('/tmp/image.png', $data);

Hope that helps.

A JDK8-style iteration:

public class IterationDemo {

    public static void main(String[] args) {
        List<Integer> list = Arrays.asList(1, 2, 3);
        list.stream().forEach(elem -> System.out.println("element " + elem));
    }
}

For rounding to non-integer values, such as 0.05:

def myround(x, prec=2, base=.05):
  return round(base * round(float(x)/base),prec)

I found this useful since I could just do a search and replace in my code to change "round(" to "myround(", without having to change the parameter values.

No need of storing resultSet values into String and again setting into POJO class. Instead set at the time you are retrieving.

Or best way switch to ORM tools like hibernate instead of JDBC which maps your POJO object direct to database.

But as of now use this:

List<User> users=new ArrayList<User>();

while(rs.next()) {
   User user = new User();      
   user.setUserId(rs.getString("UserId"));
   user.setFName(rs.getString("FirstName"));
  ...
  ...
  ...


  users.add(user);
} 

Well, after looking around the best comparison I've found so far is:

• http://www.sturmnet.org/blog/2010/03/04/poll-ioc-containers-for-net

• http://www.sturmnet.org/blog/2010/03/04/poll-results-ioc-containers-for-net

It was a poll taken in March 2010.

One point of interest to me is that people who've used a DI/IoC Framework and liked/disliked it, StructureMap appears to come out on top.

Also from the poll, it seems that Castle.Windsor and StructureMap seem to be most highly favoured.

Interestingly, Unity and Spring.Net seem to be the popular options which are most generally disliked. (I was considering Unity out of laziness (and Microsoft badge/support), but I'll be looking more closely at Castle Windsor and StructureMap now.)

Of course this probably (?) doesn't apply to Unity 2.0 which was released in May 2010.

Hopefully someone else can provide a comparison based on direct experience.

{
return txtDate.match(/^d\d?\/\d\d?\/\d\d\d\d$/);
}

This is actually being proposed in CSS4

Working draft at the W3C

Quote:

These two properties allow a website or user to require an element’s font size to be clamped within the range supplied with these two properties. If the computed value font-size is outside the bounds created by font-min-size and font-max-size, the use value of font-size is clamped to the values specified in these two properties.

This would actually work as following:

.element {
    font-min-size: 10px;
    font-max-size: 18px;
    font-size: 5vw; // viewport-relative units are responsive.
}

This would literally mean, the font size will be 5% of the viewport's width, but never smaller than 10 pixels, and never larger than 18 pixels.

Unfortunately, this feature isn't implemented anywhere yet, (not even on caniuse.com).

Just replace the form.submit function with your own implementation:

var form = document.getElementById('form');
var formSubmit = form.submit; //save reference to original submit function

form.onsubmit = function(e)
{
    formHandler();
    return false;
};

var formHandler = form.submit = function()
{
    alert('hi there');
    formSubmit(); //optionally submit the form
};

There some kind of old school 'Marxismic' way to the cast int -> bool without C4800 warnings of Microsoft's cl compiler - is to use negation of negation.

int  i  = 0;
bool bi = !!i;

int  j  = 1;
bool bj = !!j;

This is supposedly because you trying to make cross-domain request, or something that is clarified as it. You could try adding header('Access-Control-Allow-Origin: *'); to the requested file.

Also, such problem is sometimes occurs on server-sent events implementation in case of using event-source or XHR polling in IE 8-10 (which confused me first time).

Do this. Add this to the bottom of your doc just before you close the body tag.

<script>
    function canvasToImg() {
      var canvas = document.getElementById("yourCanvasID");
      var ctx=canvas.getContext("2d");
      //draw a red box
      ctx.fillStyle="#FF0000";
      ctx.fillRect(10,10,30,30);

      var url = canvas.toDataURL();

      var newImg = document.createElement("img"); // create img tag
      newImg.src = url;
      document.body.appendChild(newImg); // add to end of your document
    }

    canvasToImg(); //execute the function
</script>

Of course somewhere in your doc you need the canvas tag that it will grab.

<canvas id="yourCanvasID" />

I found myself wanting to do this too recently, so I created a tool called Shrinkwrap that uses FFmpeg to transcode videos, while preserving as much of the original metadata as possible (including file modification timestamps).

You can run it as a docker container:

docker run -v /path/to/your/videos:/vids bennetimo/shrinkwrap \
--input-extension mp4 --ffmpeg-opts crf=22,preset=fast /vids

Where:

• /path/to/your/videos/ is where the videos are that you want to convert
• --input-extension is the type of videos you want to process, here .mp4
• --ffmpeg-opts is any arbitrary FFmpeg options you want to use to customise the transcode

Then it will recursively find all of the video files that match the extension and transcode them all into files of the same name with a -tc suffix.

For more configuration options, presets for GoPro etc, see the readme.

Hope this helps someone!

TransForm three formats of Data to FormData :

1. Single value like string, Number or Boolean

 let sampleData = {
  activityName: "Hunting3",
  activityTypeID: 2,
  seasonAssociated: true, 
};

2. Array to be Array of Objects

let sampleData = {
   activitySeason: [
    { clientId: 2000, seasonId: 57 },
    { clientId: 2000, seasonId: 57 },
  ],
};

3. Object holding key value pair

let sampleData = {
    preview: { title: "Amazing World", description: "Here is description" },
};

The that make our life easy:

function transformInToFormObject(data) {
  let formData = new FormData();
  for (let key in data) {
    if (Array.isArray(data[key])) {
      data[key].forEach((obj, index) => {
        let keyList = Object.keys(obj);
        keyList.forEach((keyItem) => {
          let keyName = [key, "[", index, "]", ".", keyItem].join("");
          formData.append(keyName, obj[keyItem]);
        });
      });
    } else if (typeof data[key] === "object") { 
      for (let innerKey in data[key]) {
        formData.append(`${key}.${innerKey}`, data[key][innerKey]);
      }
    } else {
      formData.append(key, data[key]);
    }
  }
  return formData;
}

Example : Input Data

let sampleData = {
  activityName: "Hunting3",
  activityTypeID: 2,
  seasonAssociated: true,
  activitySeason: [
    { clientId: 2000, seasonId: 57 },
    { clientId: 2000, seasonId: 57 },
  ],
  preview: { title: "Amazing World", description: "Here is description" },
};

Output FormData :

activityName: Hunting3
activityTypeID: 2
seasonAssociated: true
activitySeason[0].clientId: 2000
activitySeason[0].seasonId: 57
activitySeason[1].clientId: 2000
activitySeason[1].seasonId: 57
preview.title: Amazing World
preview.description: Here is description

dropdownlist.ClearSelection(); //making sure the previous selection has been cleared
dropdownlist.Items.FindByValue(value).Selected = true;

If you're trying to grab a range with a dynamically generated string, then you just have to build the string like this:

Range(firstcol & firstrow & ":" & secondcol & secondrow).Select

I did not see this exact syntax posted yet, and it worked for me in an ES6/Webpack environment:

import $ from "jquery";

Taken directly from jQuery's NPM page. Hope this helps someone.

You can define a Root ng-App and in this ng-App you can define multiple nd-Controler. Like this

if 'empty' is not the best choice, what about this:

if (array_intersect($people, $criminals)) {...} //when found

or

if (!array_intersect($people, $criminals)) {...} //when not found

If you have multiple recurrences from a single string and you have different [start] and [\end] pattern. Here's a function which output an array.

function get_string_between($string, $start, $end){
    $split_string       = explode($end,$string);
    foreach($split_string as $data) {
         $str_pos       = strpos($data,$start);
         $last_pos      = strlen($data);
         $capture_len   = $last_pos - $str_pos;
         $return[]      = substr($data,$str_pos+1,$capture_len);
    }
    return $return;
}

Reference

If you were trying to do what I imagine you were trying to do, then you only have to treat scope like a regular JS object.

This is what I use for an API success response for JSON data array...

function(data){

    $scope.subjects = [];

    $.each(data, function(i,subject){
        //Store array of data types
        $scope.subjects.push(subject.name);

        //Split data in to arrays
        $scope[subject.name] = subject.data;
    });
}

Now {{subjects}} will return an array of data subject names, and in my example there would be a scope attribute for {{jobs}}, {{customers}}, {{staff}}, etc. from $scope.jobs, $scope.customers, $scope.staff

I found that functions cannot be written in ~/.cshrc file. Here in alias which takes arguments

for example, arguments passed to 'find' command

alias fl "find . -name '\!:1'"     
Ex: >fl abc

where abc is the argument passed as !:1

const char* is a pointer to a constant character
char* const is a constant pointer to a character
const char* const is a constant pointer to a constant character

<xsl:variable name="upper">UPPER CASE</xsl:variable>
<xsl:variable name="lower" select="translate($upper,'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz')"/>
<xsl:value-of select ="$lower"/>

//displays UPPER CASE as upper case

In case a (transitive) dependency still uses the jre variant of the Kotlin library, you can force the use of the jdk variant with the help of a resolution strategy:

configurations.all {
    resolutionStrategy {
        eachDependency { DependencyResolveDetails details ->
            details.requested.with {
                if (group == "org.jetbrains.kotlin" && name.startsWith("kotlin-stdlib-jre")) {
                    details.useTarget(group: group, name: name.replace("jre", "jdk"), version: version)
                    details.because("Force use of 'kotlin-stdlib-jdk' in favor of deprecated 'kotlin-stdlib-jre'.")
                }
            }
        }
    }
}

While jm-'s answer is the best way to handle this case, for future reference it is possible to access child scopes using a scope's $$childHead, $$childTail, $$nextSibling and $$prevSibling members. These aren't documented so they might change without notice, but they're there if you really need to traverse scopes.

// get $$childHead first and then iterate that scope's $$nextSiblings
for(var cs = scope.$$childHead; cs; cs = cs.$$nextSibling) {
    // cs is child scope
}

Fiddle

For triggers in general, you need to use a cursor to handle inserts or updates of multiple rows. For example:

DECLARE @Attribute;
DECLARE @ParameterValue;
DECLARE mycursor CURSOR FOR SELECT Attribute, ParameterValue FROM inserted;
OPEN mycursor;
FETCH NEXT FROM mycursor into @Attribute, @ParameterValue;
WHILE @@FETCH_STATUS = 0
BEGIN

If @Attribute LIKE 'NoHist_%'
      Begin
          Return
      End

etc.

FETCH NEXT FROM mycursor into @Attribute, @ParameterValue;
END

Triggers, at least in SQL Server, are a big pain and I avoid using them at all.

Why not just target the ones you want (demo)?

$('form').find('input[type=text],textarea,select').filter(':visible:first');

Edit

Or use jQuery :input selector to filter form descendants.

$('form').find('*').filter(':input:visible:first');

Don't know how you want to format it, but you can do:

print("Created at %s:%s" % (t1.hour, t1.minute))

for example.

I am late here, but this might help someone looking for the answer. Typically servletRequest.getRemoteAddr() works.

In many cases your application users might be accessing your web server via a proxy server or maybe your application is behind a load balancer.

So you should access the X-Forwarded-For http header in such a case to get the user's IP address.

e.g. String ipAddress = request.getHeader("X-FORWARDED-FOR");

Hope this helps.

You can use a post-commit hook.

Put the post-commit hook script in the hooks folder, create a wget_folder in your C:\ drive, and put the wget.exe file in this folder. Add the following code in the file called post-commit.bat

SET REPOS=%1   
SET REV=%2

FOR /f "tokens=*" %%a IN (  
'svnlook uuid %REPOS%'  
) DO (  
SET UUID=%%a  
)  

FOR /f "tokens=*" %%b IN (  
'svnlook changed --revision %REV% %REPOS%'  
) DO (  
SET POST=%%b   
)

echo %REPOS% ----- 1>&2

echo %REV% -- 1>&2

echo %UUID% --1>&2

echo %POST% --1>&2

C:\wget_folder\wget ^   
    --header="Content-Type:text/plain" ^   
    --post-data="%POST%" ^   
    --output-document="-" ^   
    --timeout=2 ^     
    http://localhost:9090/job/Test/build/%UUID%/notifyCommit?rev=%REV%    

where Test = name of the job

echo is used to see the value and you can also add exit 2 at the end to know about the issue and whether the post-commit hook script is running or not.

Try realpath.

~ $ sudo apt-get install realpath  # may already be installed
~ $ realpath .bashrc
/home/username/.bashrc

To avoid expanding symlinks, use realpath -s.

The answer comes from "bash/fish command to print absolute path to a file".

No need to define a new interface when you can use an existing one: android.os.Handler.Callback. Pass an object of type Callback, and invoke callback's handleMessage(Message msg).

The reason it doesn't work in Safari is because you're using attribute syntax. This will work fine though:

script_tag.addEventListener('error', function(){/*...*/}, true);

...except in IE.

If you want to check the script executed successfully, just set a variable using that script and check for it being set in the outer code.

In the beaten-up MVC pattern, the Servlet is "C" - controller.

Its main job is to do initial request evaluation and then dispatch the processing based on the initial evaluation to the specific worker. One of the worker's responsibilities may be to setup some presentation layer beans and forward the request to the JSP page to render HTML. So, for this reason alone, you need to pass the request object to the service layer.

I would not, though, start writing raw Servlet classes. The work they do is very predictable and boilerplate, something that framework does very well. Fortunately, there are many available, time-tested candidates ( in the alphabetical order ): Apache Wicket, Java Server Faces, Spring to name a few.

Why not just load the frame off screen or hidden and then display it once it has finished loading. You could show a loading icon in its place to begin with to give the user immediate feedback that it's loading.

The validate_required function seems to expect an HTML form control (e.g, text input field) as first argument, and check whether there is a value there at all. That is not what you want in this case.

Also, when you write ['password'].value, you create a new array of length one, containing the string 'password', and then read the non-existing property "value" from it, yielding the undefined value.

What you may want to try instead is:

if (password.value != cpassword.value) { cpassword.focus(); return false; }

(You also need to write the error message somehow, but I can't see from your code how that is done.).

I created custom styles by just overriding jQuery classes in inline style. So on top of the page, you have the jQuery CSS linked and right after that override the classes you need to modify:

<head>
    <link href="/Content/theme/base/jquery.ui.all.css" rel="stylesheet"/>

    <style type="text/css">
        .ui-dialog .ui-dialog-content
        {
            position: relative;
            border: 0;
            padding: .5em 1em;
            background: none;
            overflow: auto;
            zoom: 1;
            background-color: #ffd;
            border: solid 1px #ea7;
        }

        .ui-dialog .ui-dialog-titlebar
        {
            display:none;
        }

        .ui-widget-content
        {
            border:none;
        }
    </style>
</head>

Apart from the Distinct extension method of LINQ, you could use a HashSet<T> object that you initialise with your collection. This is most likely more efficient than the LINQ way, since it uses hash codes (GetHashCode) rather than an IEqualityComparer).

In fact, if it's appropiate for your situation, I would just use a HashSet for storing the items in the first place.

Convert dictionary into JSON (string)

import json 

mydict = { "name" : "Don", 
          "surname" : "Mandol", 
          "age" : 43} 

result = json.dumps(mydict)

print(result[0:20])

will get you:

{"name": "Don", "sur

Convert string into dictionary

back_to_mydict = json.loads(result) 

When I create a root class, whose methods I defined using the arrow functions. When inheriting and overwriting the original function I noticed the same issue.

class C {
  x = () => 1; 
 };
 
class CC extends C {
  x = (foo) =>  super.x() + foo;
};

let add = new CC;
console.log(add.x(4));

this is solved by defining the method of the parent class without arrow functions

class C {
  x() { 
    return 1; 
  }; 
 };
 
class CC extends C {
  x = foo =>  super.x() + foo;
};

let add = new CC;
console.log(add.x(4));

I came across the same problem. I properly installed the MYSQL Workbench 6.x, but faced the connection as below:

I did a bit R&D on this and found that MySQL service in service.msc is not present. To achieve this I created a new connection in MySQL Workbench then manually configured the MySQL Database Server in "System Profile" (see the below picture).

You also need to install MySQL Database Server and set a configuration file path for my.ini. Now at last test the connection (make sure MySQL service is running in services.msc).

For a paranoid like me, I'd prefer this one

TEMPLATE_DIRS = (
    __file__.rsplit('/', 2)[0] + '/templates',
)

I find it very interesting that no one considered using UTC since it is not subject to DST. Therefore, I propose the following:

function daysIntoYear(date){
    return (Date.UTC(date.getFullYear(), date.getMonth(), date.getDate()) - Date.UTC(date.getFullYear(), 0, 0)) / 24 / 60 / 60 / 1000;
}

You can test it with the following:

[new Date(2016,0,1), new Date(2016,1,1), new Date(2016,2,1), new Date(2016,5,1), new Date(2016,11,31)]
    .forEach(d => 
        console.log(`${d.toLocaleDateString()} is ${daysIntoYear(d)} days into the year`));

Which outputs for the leap year 2016 (verified using http://www.epochconverter.com/days/2016):

1/1/2016 is 1 days into the year
2/1/2016 is 32 days into the year
3/1/2016 is 61 days into the year
6/1/2016 is 153 days into the year
12/31/2016 is 366 days into the year

It seems no one has mentioned about using nonNull method which also can be used with streams in Java 8 to remove null (but not empty) as:

String[] origArray = {"Apple", "", "Cat", "Dog", "", null};
String[] cleanedArray = Arrays.stream(firstArray).filter(Objects::nonNull).toArray(String[]::new);
System.out.println(Arrays.toString(origArray));
System.out.println(Arrays.toString(cleanedArray));

And the output is:

[Apple, , Cat, Dog, , null]

[Apple, , Cat, Dog, ]

If we want to incorporate empty also then we can define a utility method (in class Utils(say)):

public static boolean isEmpty(String string) {
        return (string != null && string.isEmpty());
    }

And then use it to filter the items as:

Arrays.stream(firstArray).filter(Utils::isEmpty).toArray(String[]::new);

I believe Apache common also provides a utility method StringUtils.isNotEmpty which can also be used.
