I faced with the same problem and this worked.

While Loop is an obsolete structure, I would recommend you to replace "While loop" to "Do While..loop", and you will able to use Exit clause.

check = 0 

Do while not rs.EOF 
   if rs("reg_code") = rcode then 
      check = 1 
      Response.Write ("Found") 
      Exit do
   else 
      rs.MoveNext 
    end if 
Loop 

if check = 0 then 
   Response.Write "Not Found" 
end if}

I suppose that 255 in 227./255 is perceived as an integer and divide is always return 0

For anyone completely new to Qt Creator like me, you can modify your project's .pro file from within Qt Creator:

Just double-click on "your project name".pro in the Projects window and add the include path at the bottom of the .pro file like I've done.

By using a combination of JQuery's .trigger() and native Javascripts's .reset() all form elements can be reset to blank state.

$(".reset").click(function(){
    $("#<form_id>").trigger("reset");
});

Replace <form_id> with id of form to reset.

Use %03d in the format specifier for the integer. The 0 means that the number will be zero-filled if it is less than three (in this case) digits.

See the Formatter docs for other modifiers.

After the update you have done,

1. its first calling the FirstAjax action with default HttpGet request and renders the blank Html view . (Earlier you were not having it)
2. later on loading of DOM elements of that view your Ajax call get fired and displays alert.

Earlier you were only returning JSON to browser without rendering any HTML. Now it has a HTML view rendered where it can get your JSON Data.

You can't directly render JSON its plain data not HTML.

The APK file is in the /workspace/PROJECT_FOLDER/bin directory. To install the APK file in a real device:

1. Connect your real device with a PC/laptop.

2. Go to sdk/tools/ using a terminal or command prompt.

3. adb install <FILE PATH OF .APK FILE>

That's it...

The form's "on submit" handlers are called before the form is submitted. I don't know if there is a handler to be called after the form is submited. In the traditional non-Javascript sense the form submission will reload the page.

Lumisoft.net has both IMAP client and server code that you can use.

I've used it to download email from Gmail. The object model isn't the best, but it is workable, and seems to be rather flexible and stable.

Here is the partial result of my spike to use it. It fetches the first 10 headers with envelopes, and then fetches the full message:

using (var client = new IMAP_Client())
{
    client.Connect(_hostname, _port, _useSsl);
    client.Authenticate(_username, _password);
    client.SelectFolder("INBOX");
     var sequence = new IMAP_SequenceSet();
    sequence.Parse("0:10");
    var fetchItems = client.FetchMessages(sequence, IMAP_FetchItem_Flags.Envelope | IMAP_FetchItlags.UID,
                                        false, true);
    foreach (var fetchItem in fetchItems)
    {
        Console.Out.WriteLine("message.UID = {0}", fetchItem.UID);
        Console.Out.WriteLine("message.Envelope.From = {0}", fetchItem.Envelope.From);
        Console.Out.WriteLine("message.Envelope.To = {0}", fetchItem.Envelope.To);
        Console.Out.WriteLine("message.Envelope.Subject = {0}", fetchItem.Envelope.Subject);
        Console.Out.WriteLine("message.Envelope.MessageID = {0}", fetchItem.Envelope.MessageID);
    }
    Console.Out.WriteLine("Fetching bodies");
    foreach (var fetchItem in client.FetchMessages(sequence, IMAP_FetchItem_Flags.All, false, true)
    {             
        var email = LumiSoft.Net.Mail.Mail_Message.ParseFromByte(fetchItem.MessageData);             
        Console.Out.WriteLine("email.BodyText = {0}", email.BodyText);

    }
}

Insert in your action button this:

data-backdrop="false"

and

data-dismiss="modal" 

example:

<button type="button" class="btn btn-default" data-dismiss="modal">Done</button>

<button type="button" class="btn btn-danger danger" data-dismiss="modal" data-backdrop="false">Action</button>

if you enter this data-attr the .modal-backdrop will not appear. documentation about it at this link :http://getbootstrap.com/javascript/#modals-usage

You need to give relative or absolute or fixed positioning to your container (#shop) and set its zIndex to say 100.

You also need to give say relative positioning to your elements with the class content and lower zIndex say 97.

Do the above-mentioned with your images too and set their zIndex to 91.

And then position your button higher by setting its position to absolute and zIndex to 95

To check if a Windows service named MySuperServiceVersion1 exists, even when you might not be sure of its exact name, you could employ a wildcard, using a substring like so:

 if (Get-Service -Name "*SuperService*" -ErrorAction SilentlyContinue)
{
    # do something
}

This is possible to do without an iframe specifically. jQuery is utilised since it's mentioned in the title.

if you run in Jenkins, you can use GIT_BRANCH variable as appears here: https://wiki.jenkins-ci.org/display/JENKINS/Git+Plugin

The git plugin sets several environment variables you can use in your scripts:

GIT_COMMIT - SHA of the current

GIT_BRANCH - Name of the branch currently being used, e.g. "master" or "origin/foo"

GIT_PREVIOUS_COMMIT - SHA of the previous built commit from the same branch (the current SHA on first build in branch)

GIT_URL - Repository remote URL

GIT_URL_N - Repository remote URLs when there are more than 1 remotes, e.g. GIT_URL_1, GIT_URL_2

GIT_AUTHOR_EMAIL - Committer/Author Email

GIT_COMMITTER_EMAIL - Committer/Author Email

Swift 4.*

I have created a Xib for UICollectionViewCell which seems to be the good approach.

extension ViewController: UICollectionViewDelegateFlowLayout {

    func collectionView(_ collectionView: UICollectionView, layout collectionViewLayout: UICollectionViewLayout, sizeForItemAt indexPath: IndexPath) -> CGSize {
        return size(indexPath: indexPath)
    }

    private func size(for indexPath: IndexPath) -> CGSize {
        // load cell from Xib
        let cell = Bundle.main.loadNibNamed("ACollectionViewCell", owner: self, options: nil)?.first as! ACollectionViewCell

        // configure cell with data in it
        let data = self.data[indexPath.item]
        cell.configure(withData: data)

        cell.setNeedsLayout()
        cell.layoutIfNeeded()

        // width that you want
        let width = collectionView.frame.width
        let height: CGFloat = 0

        let targetSize = CGSize(width: width, height: height)

        // get size with width that you want and automatic height
        let size = cell.contentView.systemLayoutSizeFitting(targetSize, withHorizontalFittingPriority: .defaultHigh, verticalFittingPriority: .fittingSizeLevel)
        // if you want height and width both to be dynamic use below
        // let size = cell.contentView.systemLayoutSizeFitting(UILayoutFittingCompressedSize)

        return size
    }
}

#note: I don't recommend setting image when configuring data in this size determining case. It gave me the distorted/unwanted result. Configuring texts only gave me below result.

The simplest way I found was this: Creates a TextView or LinearLayout and places it along with the Spinner in a RelativeLayout. Initially the textview will have the text as if it were the hint "Select one ...", after the first click this TextView is invisible, disabled and calls the Spinner that is right behind it.

Step 1:

In the activity.xml that finds the spinner put:

 <RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
    <Spinner
        android:id="@+id/sp_main"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:spinnerMode="dropdown" />
    <LinearLayout
        android:id="@+id/ll_hint_spinner"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center">
        <TextView

            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:text="Select..."/>

    </LinearLayout>
</RelativeLayout>

Step 2:

In your Activity.java type:

public class MainActivity extends AppCompatActivity {

    private LinearLayout ll_hint_spinner;
    private Spinner sp_main;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ll_hint_spinner = findViewById(R.id.ll_hint_spinner);
        sp_main = findViewById(R.id.sp_main);
        //Action after clicking LinearLayout / Spinner;
        ll_hint_spinner.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //By clicking "Select ..." the Spinner is requested;
                sp_main.performClick();
                //Make LinearLayout invisible
                setLinearVisibility(false);
                //Disable LinearLayout
                ll_hint_spinner.setEnabled(false);
                //After LinearLayout is off, Spinner will function normally;
                sp_main.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                    @Override
                    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                        sp_main.setSelection(position);
                    }
                    @Override
                    public void onNothingSelected(AdapterView<?> parent) {
                        setLinearVisibility(true);
                    }
                });
            }
        });
    }
    //Method to make LinearLayout invisible or visible;
    public void setLinearVisibility(boolean visible) {
        if (visible) {
            ll_hint_spinner.setVisibility(View.VISIBLE);
        } else {
            ll_hint_spinner.setVisibility(View.INVISIBLE);
        }
    }
}

The examples of the images I used a custom Spinner, but the result of the last example will be the same.

Note: I have the example in github: click here!

Live demo

first, check its offset every time you scroll the page

$(document).scroll(function() {
    checkOffset();
});

and make its position absolute if it has been downed under 10px before the footer.

function checkOffset() {
    if($('#social-float').offset().top + $('#social-float').height() 
                                           >= $('#footer').offset().top - 10)
        $('#social-float').css('position', 'absolute');
    if($(document).scrollTop() + window.innerHeight < $('#footer').offset().top)
        $('#social-float').css('position', 'fixed'); // restore when you scroll up
}

notice that #social-float's parent should be sibling of the footer

<div class="social-float-parent">
    <div id="social-float">
        something...
    </div>
</div>
<div id="footer">
</div>

good luck :)

You may also try Perf4J. Its a neat way of doing what you are looking for, and helps in aggregated performance statistics like mean, minimum, maximum, standard deviation and transactions per second over a set time span. An extract from http://perf4j.codehaus.org/devguide.html:

StopWatch stopWatch = new LoggingStopWatch();

try {
    // the code block being timed - this is just a dummy example
    long sleepTime = (long)(Math.random() * 1000L);
    Thread.sleep(sleepTime);
    if (sleepTime > 500L) {
        throw new Exception("Throwing exception");
    }

    stopWatch.stop("codeBlock2.success", "Sleep time was < 500 ms");
} catch (Exception e) {
    stopWatch.stop("codeBlock2.failure", "Exception was: " + e);
}

Output:

In general, you're better off validating URLs using built-in library or framework functions, rather than rolling your own regular expressions to do this - see What is the best regular expression to check if a string is a valid URL for details.

If you are keen on doing this, though, check out this question:

Getting parts of a URL (Regex)

Then, once you're satisfied with the URL (by whatever means you used to validate it), you could either use a simple "endswith" type string operator to check the extension, or a simple regex like

(?i)\.(jpg|png|gif)$

You can use lapply to pass each column to str_length, then cbind it to your original data.frame...

library(stringr)

out <- lapply( df , str_length )    
df <- cbind( df , out )

#     col1     col2 col1 col2
#1     abc adf qqwe    3    8
#2    abcd        d    4    1
#3       a        e    1    1
#4 abcdefg        f    7    1

You can use socket.settimeout() which accepts a integer argument representing number of seconds. For example, socket.settimeout(1) will set the timeout to 1 second

Another way to do it on Ubuntu 18.0.4

sudo /usr/share/kibana/bin/kibana --version

Let's have a simple one-character string 'š' and encode it into a sequence of bytes:

>>> 'š'.encode('utf-8')
b'\xc5\xa1'

For the purpose of this example let's display the sequence of bytes in its binary form:

>>> bin(int(b'\xc5\xa1'.hex(), 16))
'0b1100010110100001'

Now it is generally not possible to decode the information back without knowing how it was encoded. Only if you know that the utf-8 text encoding was used, you can follow the algorithm for decoding utf-8 and acquire the original string:

11000101 10100001
   ^^^^^   ^^^^^^
   00101   100001

You can display the binary number 101100001 back as a string:

>>> chr(int('101100001', 2))
'š'

By doing so you'd be able to control any action of the framed page, which you cannot. Same-domain origin policy applies.

If you use Eclipse Collections:

MutableSet<Integer> mSet = Lists.mutable.with(1, 2, 3).toSet();
MutableIntSet mIntSet = IntLists.mutable.with(1, 2, 3).toSet();

The MutableSet interface extends java.util.Set whereas the MutableIntSet interface does not. You can also convert any Iterable to a Set using the Sets factory class.

Set<Integer> set = Sets.mutable.withAll(List.of(1, 2, 3));

There is more explanation of the mutable factories available in Eclipse Collections here.

If you want an ImmutableSet from a List, you can use the Sets factory as follows:

ImmutableSet<Integer> immutableSet = Sets.immutable.withAll(List.of(1, 2, 3))

Note: I am a committer for Eclipse Collections

You don't need to write a converter, just do this in your handler/codebehind:

int i = Convert.ToInt32(txtMyTextBox.Text);

OR

int i = int.Parse(txtMyTextBox.Text);

The Text property of your textbox is a String type, so you have to perform the conversion in the code.

Here's how to do it:

var myVideo = document.getElementById("my-video")    
myVideo.controls = false;

Replace @RunWith(MockitoJUnitRunner.class) with @RunWith(MockitoJUnitRunner.Silent.class).

Nearly all database (and database-like) programs use a binary tree to implement their indexing systems.

Simple-to-code O(N + K*log(K)) way

Take a random sample without replacement of the indices, sort the indices, and take them from the original.

indices = random.sample(range(len(myList)), K)
[myList[i] for i in sorted(indices)]

Or more concisely:

[x[1] for x in sorted(random.sample(enumerate(myList),K))]

Optimized O(N)-time, O(1)-auxiliary-space way

You can alternatively use a math trick and iteratively go through myList from left to right, picking numbers with dynamically-changing probability (N-numbersPicked)/(total-numbersVisited). The advantage of this approach is that it's an O(N) algorithm since it doesn't involve sorting!

from __future__ import division

def orderedSampleWithoutReplacement(seq, k):
    if not 0<=k<=len(seq):
        raise ValueError('Required that 0 <= sample_size <= population_size')

    numbersPicked = 0
    for i,number in enumerate(seq):
        prob = (k-numbersPicked)/(len(seq)-i)
        if random.random() < prob:
            yield number
            numbersPicked += 1

Proof of concept and test that probabilities are correct:

Simulated with 1 trillion pseudorandom samples over the course of 5 hours:

>>> Counter(
        tuple(orderedSampleWithoutReplacement([0,1,2,3], 2))
        for _ in range(10**9)
    )
Counter({
    (0, 3): 166680161, 
    (1, 2): 166672608, 
    (0, 2): 166669915, 
    (2, 3): 166667390, 
    (1, 3): 166660630, 
    (0, 1): 166649296
})

Probabilities diverge from true probabilities by less a factor of 1.0001. Running this test again resulted in a different order meaning it isn't biased towards one ordering. Running the test with fewer samples for [0,1,2,3,4], k=3 and [0,1,2,3,4,5], k=4 had similar results.

edit: Not sure why people are voting up wrong comments or afraid to upvote... NO, there is nothing wrong with this method. =)

(Also a useful note from user tegan in the comments: If this is python2, you will want to use xrange, as usual, if you really care about extra space.)

edit: Proof: Considering the uniform distribution (without replacement) of picking a subset of k out of a population seq of size len(seq), we can consider a partition at an arbitrary point i into 'left' (0,1,...,i-1) and 'right' (i,i+1,...,len(seq)). Given that we picked numbersPicked from the left known subset, the remaining must come from the same uniform distribution on the right unknown subset, though the parameters are now different. In particular, the probability that seq[i] contains a chosen element is #remainingToChoose/#remainingToChooseFrom, or (k-numbersPicked)/(len(seq)-i), so we simulate that and recurse on the result. (This must terminate since if #remainingToChoose == #remainingToChooseFrom, then all remaining probabilities are 1.) This is similar to a probability tree that happens to be dynamically generated. Basically you can simulate a uniform probability distribution by conditioning on prior choices (as you grow the probability tree, you pick the probability of the current branch such that it is aposteriori the same as prior leaves, i.e. conditioned on prior choices; this will work because this probability is uniformly exactly N/k).

edit: Timothy Shields mentions Reservoir Sampling, which is the generalization of this method when len(seq) is unknown (such as with a generator expression). Specifically the one noted as "algorithm R" is O(N) and O(1) space if done in-place; it involves taking the first N element and slowly replacing them (a hint at an inductive proof is also given). There are also useful distributed variants and miscellaneous variants of reservoir sampling to be found on the wikipedia page.

edit: Here's another way to code it below in a more semantically obvious manner.

from __future__ import division
import random

def orderedSampleWithoutReplacement(seq, sampleSize):
    totalElems = len(seq)
    if not 0<=sampleSize<=totalElems:
        raise ValueError('Required that 0 <= sample_size <= population_size')

    picksRemaining = sampleSize
    for elemsSeen,element in enumerate(seq):
        elemsRemaining = totalElems - elemsSeen
        prob = picksRemaining/elemsRemaining
        if random.random() < prob:
            yield element
            picksRemaining -= 1

from collections import Counter         
Counter(
    tuple(orderedSampleWithoutReplacement([0,1,2,3], 2))
    for _ in range(10**5)

)

On SQL Server, this will list all the indexes for a specified table:

select * from sys.indexes
where object_id = (select object_id from sys.objects where name = 'MYTABLE')

This query will list all tables without an index:

SELECT name
FROM sys.tables 
WHERE OBJECTPROPERTY(object_id,'IsIndexed') = 0

And this is an interesting MSDN FAQ on a related subject:

If you're using Matplotlib interactively, for example in a web application, (e.g. ipython) you maybe looking for

plt.show()

instead of plt.close() or plt.clf().

you can use -v option from cli, this facility is not available via Dockerfile

docker run -t -i -v <host_dir>:<container_dir> ubuntu /bin/bash

where host_dir is the directory from host which you want to mount. you don't need to worry about directory of container if it doesn't exist docker will create it.

If you do any changes in host_dir from host machine (under root privilege) it will be visible to container and vice versa.

Asking for commit before pull

• git stash
• git pull origin << branchname >>

If needed :

• git stash apply

int myInt = 65;

char myChar = (char)myInt;  // myChar should now be the letter A

char[20] myString = {0}; // make an empty string.

myString[0] = myChar;
myString[1] = myChar; // Now myString is "AA"

This should all be found in any intro to C book, or by some basic online searching.

On the 1st iteration of the outer loop (i = 1), the inner loop will iterate 1 times On the 2nd iteration of the outer loop (i = 2), the inner loop will iterate 2 time On the 3rd iteration of the outer loop (i = 3), the inner loop will iterate 3 times
.
.
On the FINAL iteration of the outer loop (i = n), the inner loop will iterate n times

So, the total number of times the statements in the inner loop will be executed will be equal to the sum of the integers from 1 to n, which is:

((n)*n) / 2 = (n^2)/2 = O(n^2) times 

In my opinion, varchar(n) has it's own advantages. Yes, they all use the same underlying type and all that. But, it should be pointed out that indexes in PostgreSQL has its size limit of 2712 bytes per row.

TL;DR: If you use text type without a constraint and have indexes on these columns, it is very possible that you hit this limit for some of your columns and get error when you try to insert data but with using varchar(n), you can prevent it.

Some more details: The problem here is that PostgreSQL doesn't give any exceptions when creating indexes for text type or varchar(n) where n is greater than 2712. However, it will give error when a record with compressed size of greater than 2712 is tried to be inserted. It means that you can insert 100.000 character of string which is composed by repetitive characters easily because it will be compressed far below 2712 but you may not be able to insert some string with 4000 characters because the compressed size is greater than 2712 bytes. Using varchar(n) where n is not too much greater than 2712, you're safe from these errors.

You dont need call addSheet() method. After creating sheet, it already add to excel. Here i fixed some codes:

    //First sheet
    $sheet = $objPHPExcel->getActiveSheet();

    //Start adding next sheets
    $i=0;
    while ($i < 10) {

      // Add new sheet
      $objWorkSheet = $objPHPExcel->createSheet($i); //Setting index when creating

      //Write cells
      $objWorkSheet->setCellValue('A1', 'Hello'.$i)
                   ->setCellValue('B2', 'world!')
                   ->setCellValue('C1', 'Hello')
                   ->setCellValue('D2', 'world!');

      // Rename sheet
      $objWorkSheet->setTitle("$i");

      $i++;
    }

Okay turned out that I made a really silly mistake. The device I am using for testing is running Android 4.0.4, API level 15.

The styles.xml file that I was editing is in the default values folder. I edited the styles.xml in values-v14 folder and it works all fine now.

Following method will show Notification, having big text and freeze enabled( Notification will not get removed even after user swipes ). We need NotificationManager service

public static void showNotificationOngoing(Context context,String title) {
        NotificationManager notificationManager =
                (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);

        PendingIntent contentIntent = PendingIntent.getActivity(context, 0,
                new Intent(context, MainActivity.class), PendingIntent.FLAG_UPDATE_CURRENT);

        Notification.Builder notificationBuilder = new Notification.Builder(context)
                .setContentTitle(title + DateFormat.getDateTimeInstance().format(new Date()) + ":" + accuracy)
                .setContentText(addressFragments.toString())
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(contentIntent)
                .setOngoing(true)
                .setStyle(new Notification.BigTextStyle().bigText(addressFragments.toString()))
                .setAutoCancel(true);
        notificationManager.notify(3, notificationBuilder.build());
}

Method to Remove Notifications

public static void removeNotification(Context context){
    NotificationManager notificationManager =
            (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
    notificationManager.cancelAll();
}

In Python 3.5, os.scandir is better if you need to check for file attributes or type - see os.DirEntry for properties of the object that's returned by the function.

import os 

for file in os.scandir(path):
    if file.name.endswith(".bak"):
        os.unlink(file.path)

This also doesn't require changing directories since each DirEntry already includes the full path to the file.

Save it as a .ps1 file and then execute

powershell -file "path\to your\start stop nation service command file.ps1"

HI im going to leave this here cz i cant comment due to restrictions but i found AlexFitiskin's answer perfect, but a small correction was needed

document.getElementById('here').innerHTML = data.name; 

This needed to be changed to

document.getElementById('here').innerHTML = data.n;

I know that after five years the owner of the post will not find it of any importance but this is for people who might come across in the future .

If you need permissions, you cannot use 'pip' with 'sudo'. You can do a trick, so that you can use 'sudo' and install package. Just place 'sudo python -m ...' in front of your pip command.

sudo python -m pip install --user -r package_name

you need to add Content-Disposition header, smth like this (although I used mod-python here, but principle should be the same):

request.headers_out['Content-Disposition'] = 'attachment; filename=%s' % myfname

Just in case any Windows users are having trouble, I thought I'd add my own experience. When running python manage.py runserver 0.0.0.0:8000, I could view urls using localhost:8000, but not my ip address 192.168.1.3:8000.

I ended up disabling ipv6 on my wireless adapter, and running ipconfig /renew. After this everything worked as expected.

@ local scope property is used to access string values that are defined outside the directive.

= In cases where you need to create a two-way binding between the outer scope and the directive’s isolate scope you can use the = character.

& local scope property allows the consumer of a directive to pass in a function that the directive can invoke.

Kindly check the below link which gives you clear understanding with examples.I found it really very useful so thought of sharing it.

It should be the same thing of maven.compiler.source/maven.compiler.target but the above solution works for me, otherwise the second one gets the parent specification (I have a matrioska of .pom)

VirtualBox version has many uncompatibilities with Linux version, so it's hard to install by using "Guest Addition CD image". For linux distributions it's frequently have a good companion Guest Addition package(equivalent functions to the CD image) which can be installed by:

sudo apt-get install virtualbox-guest-dkms

After that, on the window menu of the Guest, go to Devices->Shared Folders Settings->Shared Folders and add a host window folder to Machine Folders(Mark Auto-mount option) then you can see the shared folder in the Files of Guest Linux.

First of all: you should always import mockito static, this way the code will be much more readable (and intuitive):

import static org.mockito.Mockito.*;

For partial mocking and still keeping original functionality on the rest mockito offers "Spy".

You can use it as follows:

private World world = spy(new World());

To eliminate a method from being executed you could use something like this:

doNothing().when(someObject).someMethod(anyObject());

to give some custom behaviour to a method use "when" with an "thenReturn":

doReturn("something").when(this.world).someMethod(anyObject());

For more examples please find the excellent mockito samples in the doc.

Maybe you can use this function that I found on this page How do I include a JavaScript file in a JavaScript file?:

function include(filename)
{
    var head = document.getElementsByTagName('head')[0];

    var script = document.createElement('script');
    script.src = filename;
    script.type = 'text/javascript';

    head.appendChild(script)
}

• Toggle case "HellO" to "hELLo" with g~ then a movement.
• Uppercase "HellO" to "HELLO" with gU then a movement.
• Lowercase "HellO" to "hello" with gu then a movement.

For examples and more info please read this: http://vim.wikia.com/wiki/Switching_case_of_characters

$('#navigation ul li').css({'display' : 'inline-block'});

It seems a typo there ...syntax mistake :))

On my mac os maverick i try this:

• In Terminal type:

  1)mkdir -p ~/bin ~/tmp ~/lib/python3.3 ~/src 2)export TMPDIR=~/tmp
  3)wget -O ~/bin/2to3
  4)http://hg.python.org/cpython/raw-file/60c831305e73/Tools/scripts/2to3 5)chmod 700 ~/bin/2to3 6)cd ~/src 7)git clone https://github.com/petehunt/PyMySQL.git 8)cd PyMySQL/
  9)python3.3 setup.py install --install-lib=$HOME/lib/python3.3 --install-scripts=$HOME/bin

After that, enter in the python3 interpreter and type:

1. import pymysql. If there is no error your installation is ok. For verification write a script to connect to mysql with this form:

2. # a simple script for MySQL connection import pymysql db = pymysql.connect(host="localhost", user="root", passwd="*", db="biblioteca") #Sure, this is information for my db # close the connection db.close ()*

Give it a name ("con.py" for example) and save it on desktop. In Terminal type "cd desktop" and then $python con.py If there is no error, you are connected with MySQL server. Good luck!

You can write a script and then use nohup ./yourscript & to execute

For example:

vi yourscript

put

#!/bin/bash
script here

you may also need to change permission to run script on server

chmod u+rwx yourscript

finally

nohup ./yourscript &

This problem I have encountered before. It ended up being an issue with the firewall. I just added a rule to the firewall. I had to open port 1433 so the SQL server can connect to the server.

Variables names are only locally meaningful.

Once you hit

return s1,s2,s3,s4

at the end of the method, Python constructs a tuple with the values of s1, s2, s3 and s4 as its four members at index 0, 1, 2 and 3 - NOT a dictionary of variable names to values, NOT an object with variable names and their values, etc.

If you want the variable names to be meaningful after you hit return in the method, you must create an object or dictionary.

This button post to the current page while at the same time opens OtherPage.aspx in a new browser window. I think this is what you mean with ...the original page and the newly launched page should both be launched.

     onclick="myBtn_Click" OnClientClick="window.open('OtherPage.aspx', 'OtherPage');" />

I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.

Multiple connection coming from different machines/IP's should not be a problem however.

There's more info in this MSDN post:

You can also use the Record type in typescript :

export interface nameInterface { 
    propName : Record<string, otherComplexInterface> 
}

I think what you want to do is

<link rel="stylesheet" type="text/css" href="font/font-face/my-font-face.css">

In JavaScript, null is a special singleton object which is helpful for signaling "no value". You can test for it by comparison and, as usual in JavaScript, it's a good practice to use the === operator to avoid confusing type coercion:

var a = null;
alert(a === null); // true

As @rynah mentions, "undefined" is a bit confusing in JavaScript. However, it's always safe to test if the typeof(x) is the string "undefined", even if "x" is not a declared variable:

alert(typeof(x) === 'undefined'); // true

Also, variables can have the "undefined value" if they are not initialized:

var y;
alert(typeof(y) === 'undefined'); // true

Putting it all together, your check should look like this:

if ((typeof(data) !== 'undefined') && (data !== null)) {
  // ...

However, since the variable "data" is always defined since it is a formal function parameter, using the "typeof" operator is unnecessary and you can safely compare directly with the "undefined value".

function(data) {
  if ((data !== undefined) && (data !== null)) {
    // ...

This snippet amounts to saying "if the function was called with an argument which is defined and is not null..."

The C++ standard library has almost exactly that function call nth_element, although it does modify your data. It has expected linear run-time, O(N), and it also does a partial sort.

const int N = ...;
double a[N];
// ... 
const int m = ...; // m < N
nth_element (a, a + m, a + N);
// a[m] contains the mth element in a

Currently there is no way to apply a css to get your desired result . Why not use libraries like choosen or select2 . These allow you to style the way you want.

If you don want to use third party libraries then you can make a simple un-ordered list and play with some css.Here is thread you could follow

How to convert <select> dropdown into an unordered list using jquery?

Schemas logically group tables, procedures, views together. All employee-related objects in the employee schema, etc.

You can also give permissions to just one schema, so that users can only see the schema they have access to and nothing else.

Replace double quotes with single ones:

INSERT
INTO    MY.LOGFILE
        (id,severity,category,logdate,appendername,message,extrainfo)
VALUES  (
       'dee205e29ec34',
       'FATAL',
       'facade.uploader.model',
       '2013-06-11 17:16:31',
       'LOGDB',
       NULL,
       NULL
       )

In SQL, double quotes are used to mark identifiers, not string constants.

You could alter the figsize by passing a tuple showing the width, height parameters you would like to keep.

import matplotlib.pyplot as plt

fig, ax = plt.subplots(figsize=(10,10))         # Sample figsize in inches
sns.heatmap(df1.iloc[:, 1:6:], annot=True, linewidths=.5, ax=ax)

EDIT

I remember answering a similar question of yours where you had to set the index as TIMESTAMP. So, you could then do something like below:

df = df.set_index('TIMESTAMP')
df.resample('30min').mean()
fig, ax = plt.subplots()
ax = sns.heatmap(df.iloc[:, 1:6:], annot=True, linewidths=.5)
ax.set_yticklabels([i.strftime("%Y-%m-%d %H:%M:%S") for i in df.index], rotation=0)

For the head of the dataframe you posted, the plot would look like:

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

I performed a full-on cop-out and wrote a class which creates a batch file and then calls sftp via a system call. Not the nicest (or fastest) way of doing it but it works for what I need and it didn't require any installation of extra libraries or extensions in PHP.

Could be the way to go if you don't want to use the ssh2 extensions

Answer to your first question is As every object in java has only one lock(monitor) andwait(),notify(),notifyAll() are used for monitor sharing thats why they are part of Object class rather than Threadclass.

How about a single standalone function named as debug from https://github.com/hazardland/debug.php.

Typical debug() html output looks like this:

But you can output data as a plain text with same function also (with 4 space indented tabs) like this (and even log it in file if needed):

string : "Test string"
boolean : true
integer : 17
float : 9.99
array (array)
    bob : "alice"
    1 : 5
    2 : 1.4
object (test2)
    another (test3)
        string1 : "3d level"
        string2 : "123"
        complicated (test4)
            enough : "Level 4"

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

The selected answer is the good one, but is long, so you might not read the key point:

I got an error with the SSL when accesign www.example.com but it worked fine if I go to example.com

If it happens the same to you, probably your error is that in the DNS configuration you have set:

CNAME www.example.com --> example.com  (WRONG)

But, what you have to do is:

CNAME www.example.com --> username.github.io  (GOOD)

or

CNAME www.example.com --> organization.github.io  (GOOD)

That was my error

This first removes all non-letter characters, folds to lowercase, then splits the input, doing all the work in a single line:

String[] words = instring.replaceAll("[^a-zA-Z ]", "").toLowerCase().split("\\s+");

Spaces are initially left in the input so the split will still work.

By removing the rubbish characters before splitting, you avoid having to loop through the elements.

if you used pipenv:

if you installed rest_framework thru the new pipenv, you need to run it thru the virtual environment:

1.pipenv shell

2.(env) now, run your command(for example python manage.py runserver)

Use the -J compression option for xz. And remember to man tar :)

tar cfJ <archive.tar.xz> <files>

Edit 2015-08-10:

If you're passing the arguments to tar with dashes (ex: tar -cf as opposed to tar cf), then the -f option must come last, since it specifies the filename (thanks to @A-B-B for pointing that out!). In that case, the command looks like:

tar -cJf <archive.tar.xz> <files>

The ~ selector is in fact the General sibling combinator (renamed to Subsequent-sibling combinator in selectors Level 4):

The general sibling combinator is made of the "tilde" (U+007E, ~) character that separates two sequences of simple selectors. The elements represented by the two sequences share the same parent in the document tree and the element represented by the first sequence precedes (not necessarily immediately) the element represented by the second one.

Consider the following example:

.a ~ .b {_x000D_
  background-color: powderblue;_x000D_
}

<ul>_x000D_
  <li class="b">1st</li>_x000D_
  <li class="a">2nd</li>_x000D_
  <li>3rd</li>_x000D_
  <li class="b">4th</li>_x000D_
  <li class="b">5th</li>_x000D_
</ul>

.a ~ .b matches the 4th and 5th list item because they:

• Are .b elements
• Are siblings of .a
• Appear after .a in HTML source order.

Likewise, .check:checked ~ .content matches all .content elements that are siblings of .check:checked and appear after it.

You are catching the error but then you are re throwing it. You should try and handle it more gracefully, otherwise your user is going to see 500, internal server, errors.

You may want to send back a response telling the user what went wrong as well as logging the error on your server.

I am not sure exactly what errors the request might return, you may want to return something like.

router.get("/emailfetch", authCheck, async (req, res) => {
  try {
    let emailFetch = await gmaiLHelper.getEmails(req.user._doc.profile_id , '/messages', req.user.accessToken)
      emailFetch = emailFetch.data
      res.send(emailFetch)
   } catch(error) {
      res.status(error.response.status)
      return res.send(error.message);
    })

})

This code will need to be adapted to match the errors that you get from the axios call.

I have also converted the code to use the try and catch syntax since you are already using async.

Sort of combined the first two answers, with a tweak to ironfroggy's code so that it returns a tuple:

import operator

class stuple(tuple):
    def __add__(self, other):
        return self.__class__(map(operator.add, self, other))
        # obviously leaving out checking lengths

>>> a = stuple([1,2,3])
>>> b = stuple([3,2,1])
>>> a + b
(4, 4, 4)

Note: using self.__class__ instead of stuple to ease subclassing.

Implement both deprecated and non-deprecated methods like below. First one is to handle API level 21 and higher, second one is handle lower than API level 21

webViewClient = object : WebViewClient() {

        @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
        override fun shouldOverrideUrlLoading(view: WebView?, request: WebResourceRequest?): Boolean {
            parseUri(request?.url)
            return true
        }

        @SuppressWarnings("deprecation")
        override fun shouldOverrideUrlLoading(view: WebView?, url: String?): Boolean {
            parseUri(Uri.parse(url))
            return true
        }
}

• Open Notepad++
• Paste your text
• Control + H

In the pop up

• Find what: \r\n
• Replace with: BLANK_SPACE

You end up with a big line. Then

• Control + H

In the pop up

• Find what: (\.)
• Replace with: \r\n

So you end up with lines that end by dot

And if you have to do the same process lots of times

• Go to Macro
• Start recording
• Do the process above
• Go to Macro
• Stop recording
• Save current recorded macro
• Choose a short cut
• Select the text you want to apply the process (Control + A)
• Do the shortcut

Technically what you are looking for is the unset value in combination with the shorthand property all:

The unset CSS keyword resets a property to its inherited value if it inherits from its parent, and to its initial value if not. In other words, it behaves like the inherit keyword in the first case, and like the initial keyword in the second case. It can be applied to any CSS property, including the CSS shorthand all.

.customClass {
  /* specific attribute */
  color: unset; 
}

.otherClass{
  /* unset all attributes */
  all: unset; 
  /* then set own attributes */
  color: red;
}

You can use the initial value as well, this will default to the initial browser value.

.otherClass{
  /* unset all attributes */
  all: initial; 
  /* then set own attributes */
  color: red;
}

As an alternative:
If possible it is probably good practice to encapsulate the class or id in a kind of namespace:

.namespace .customClass{
  color: red;
}

<div class="namespace">
  <div class="customClass"></div>
</div>

because of the specificity of the selector this will only influence your own classes

It is easier to accomplish this in "preprocessor scripting languages" like SASS with nesting capabilities:

.namespace{
  .customClass{
    color: red
  }
}

RFC 3339 is mostly a profile of ISO 8601, but is actually inconsistent with it in borrowing the "-00:00" timezone specification from RFC 2822. This is described in the Wikipedia article.

With no argument:

ourObject = PowerMockito.spy(new OurClass());
when(ourObject , "ourPrivateMethodName").thenReturn("mocked result");

With String argument:

ourObject = PowerMockito.spy(new OurClass());
when(ourObject, method(OurClass.class, "ourPrivateMethodName", String.class))
                .withArguments(anyString()).thenReturn("mocked result");

@Column is not the appropriate annotation. You don't want to store a whole User or Question in a column. You want to create an association between the entities. Start by renaming Questions to Question, since an instance represents a single question, and not several ones. Then create the association:

@Entity
@Table(name = "UserAnswer")
public class UserAnswer {

    // this entity needs an ID:
    @Id
    @Column(name="useranswer_id")
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @ManyToOne
    @JoinColumn(name = "user_id")
    private User user;

    @ManyToOne
    @JoinColumn(name = "question_id")
    private Question question;

    @Column(name = "response")
    private String response;

    //getter and setter 
}

The Hibernate documentation explains that. Read it. And also read the javadoc of the annotations.

We know that the UDP is a connection-less protocol, so it is

1. suitable for process that require simple request-response communication.
2. suitable for process which has internal flow ,error control
3. suitable for broad casting and multicasting

Specific examples:

• used in SNMP
• used for some route updating protocols such as RIP

You are right, the documentation lacks of those methods. However when I dug into rxjs repository, I found nice comments about tap (too long to paste here) and pipe operators:

  /**
   * Used to stitch together functional operators into a chain.
   * @method pipe
   * @return {Observable} the Observable result of all of the operators having
   * been called in the order they were passed in.
   *
   * @example
   *
   * import { map, filter, scan } from 'rxjs/operators';
   *
   * Rx.Observable.interval(1000)
   *   .pipe(
   *     filter(x => x % 2 === 0),
   *     map(x => x + x),
   *     scan((acc, x) => acc + x)
   *   )
   *   .subscribe(x => console.log(x))
   */

In brief:

Pipe: Used to stitch together functional operators into a chain. Before we could just do observable.filter().map().scan(), but since every RxJS operator is a standalone function rather than an Observable's method, we need pipe() to make a chain of those operators (see example above).

Tap: Can perform side effects with observed data but does not modify the stream in any way. Formerly called do(). You can think of it as if observable was an array over time, then tap() would be an equivalent to Array.forEach().

There's a lot of talks going on regarding the simplicity of asmx web services over WCF. Let me clarify few points here.

• Its true that novice web service developers will get started easily in asmx web services. Visual Studio does all the work for them and readily creates a Hello World project.
• But if you can learn WCF (which off course wont take much time) then you can get to see that WCF is also quite simple, and you can go ahead easily.
• Its important to remember that these said complexities in WCF are actually attributed to the beautiful features that it brings along with it. There are addressing, bindings, contracts and endpoints, services & clients all mentioned in the config file. The beauty is your business logic is segregated and maintained safely. Tomorrow if you need to change the binding from basicHttpBinding to netTcpBinding you can easily create a binding in config file and use it. So all the changes related to clients, communication channels, bindings etc are to be done in the configuration leaving the business logic safe & intact, which makes real good sense.
• WCF "web services" are part of a much broader spectrum of remote communication enabled through WCF. You will get a much higher degree of flexibility and portability doing things in WCF than through traditional ASMX because WCF is designed, from the ground up, to summarize all of the different distributed programming infrastructures offered by Microsoft. An endpoint in WCF can be communicated with just as easily over SOAP/XML as it can over TCP/binary and to change this medium is simply a configuration file mod. In theory, this reduces the amount of new code needed when porting or changing business needs, targets, etc.
• Web Services can be accessed only over HTTP & it works in stateless environment, where WCF is flexible because its services can be hosted in different types of applications. You can host your WCF services in Console, Windows Services, IIS & WAS, which are again different ways of creating new projects in Visual Studio.
• ASMX is older than WCF, and anything ASMX can do so can WCF (and more). Basically you can see WCF as trying to logically group together all the different ways of getting two apps to communicate in the world of Microsoft; ASMX was just one of these many ways and so is now grouped under the WCF umbrella of capabilities.
• You will always like to use Visual Studio for NET 4.0 or 4.5 as it makes life easy while creating WCF services.
• The major difference is that Web Services Use XmlSerializer. But WCF Uses DataContractSerializer which is better in Performance as compared to XmlSerializer. That's why WCF performs way better than other communication technology counterparts from .NET like asmx, .NET remoting etc.

Not to forget that I was one of those guys who liked asmx services more than WCF, but that time I was not well aware of WCF services and its capabilities. I was scared of the WCF configurations. But I dared and and tried writing few WCF services of my own, and when I learnt more of WCF, now I have no inhibitions about WCF and I recommend them to anyone & everyone. Happy coding!!!

The new method is:

[self dismissViewControllerAnimated:NO completion:nil];

The word modal has been removed; As it has been for the presenting API call:

[self presentViewController:vc animated:NO completion:nil];

The reasons were discussed in the 2012 WWDC Session 236 - The Evolution of View Controllers on iOS Video. Essentially, view controllers presented by this API are no longer always modal, and since they were adding a completion handler it was a good time to rename it.

In response to comment from Marc:

What's the best way to support all devices 4.3 and above? The new method doesn't work in iOS4, yet the old method is deprecated in iOS6.

I realize that this is almost a separate question, but I think it's worth a mention since not everyone has the money to upgrade all their devices every 3 years so many of us have some older (pre 5.0) devices. Still, as much as it pains me to say it, you need to consider if it is worth targeting below 5.0. There are many new and cool APIs not available below 5.0. And Apple is continually making it harder to target them; armv6 support is dropped from Xcode 4.5, for example.

To target below 5.0 (as long as the completion block is nil) just use the handy respondsToSelector: method.

if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
    [self presentViewController:test animated:YES completion:nil];
} else {
    [self presentModalViewController:test animated:YES];
}

In response to another comment from Marc:

That could be quite a lot of If statements in my application!...I was thinking of creating a category that encapsulated this code, would creating a category on UIViewControler get me rejected?

and one from Full Decent:

...is there a way to manually cause that to not present a compiler warning?

Firstly, no, creating a category on UIViewController in and of itself will not get your app rejected; unless that category method called private APIs or something similar.

A category method is an exceedingly good place for such code. Also, since there would be only one call to the deprecated API, there would be only one compiler warning.

To address Full Decent's comment(question), yes you can suppress compiler warnings manually. Here is a link to an answer on SO on that very subject. A category method is also a great place to suppress a compiler warning, since you're only suppressing the warning in one place. You certainly don't want to go around silencing the compiler willy-nilly.

If I was to write a simple category method for this it might be something like this:

@implementation UIViewController (NJ_ModalPresentation)
-(void)nj_presentViewController:(UIViewController *)viewControllerToPresent animated:(BOOL)flag completion:(void (^)(void))completion{
    NSAssert(completion == nil, @"You called %@ with a non-nil completion. Don't do that!",NSStringFromSelector(_cmd));
    if ([self respondsToSelector:@selector(presentViewController:animated:completion:)]){
        [self presentViewController:viewControllerToPresent animated:flag completion:completion];
    } else {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
        [self presentModalViewController:viewControllerToPresent animated:flag];
#pragma clang diagnostic pop
    }
}
@end

This is how I set it up:

1. Open the command prompt(CMD) as administrator.

2. Export the proxy settings :

   set http_proxy=http://username:password@proxyAddress:port

   set https_proxy=https://username:password@proxyAddress:port

3. Install the package you want to install:

   pip install PackageName

For example:

At the moment there is no command in MongoDB that would do this. Please note the JIRA ticket with related feature request.

You could do something like:

db.<collection_name>.find().forEach(function(d){ db.getSiblingDB('<new_database>')['<collection_name>'].insert(d); });

Please note that with this, the two databases would need to share the same mongod for this to work.

Besides this, you can do a mongodump of a collection from one database and then mongorestore the collection to the other database.

using System;
using System.IO;
using System.IO.Compression;

namespace ConsoleApplication
{
    class Program`enter code here`
    {
        static void Main(string[] args)
        {
            using (FileStream zipToOpen = new FileStream(@"c:\users\exampleuser\release.zip", FileMode.Open))
            {
                using (ZipArchive archive = new ZipArchive(zipToOpen, ZipArchiveMode.Update))
                {
                    ZipArchiveEntry readmeEntry = archive.CreateEntry("Readme.txt");
                    using (StreamWriter writer = new StreamWriter(readmeEntry.Open()))
                    {
                            writer.WriteLine("Information about this package.");
                            writer.WriteLine("========================");
                    }
                }
            }
        }
    }
}

The difference is unlikely to matter:

• If your strings are small, the malloc will drown out the string concatenations.
• If your strings are large, the time spent copying the data will drown out the differences between strcat / sprintf.

As other posters have mentioned, this is a premature optimization. Concentrate on algorithm design, and only come back to this if profiling shows it to be a performance problem.

That said... I suspect method 1 will be faster. There is some---admittedly small---overhead to parse the sprintf format-string. And strcat is more likely "inline-able".

As an update...with ECMAScript 6 you can FINALLY set default values in function parameter declarations like so:

function f (x, y = 7, z = 42) {
  return x + y + z
}

f(1) === 50

You can't do this with jQuery ajax, but with native XMLHttpRequest.

var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function(){
    if (this.readyState == 4 && this.status == 200){
        //this.response is what you're looking for
        handler(this.response);
        console.log(this.response, typeof this.response);
        var img = document.getElementById('img');
        var url = window.URL || window.webkitURL;
        img.src = url.createObjectURL(this.response);
    }
}
xhr.open('GET', 'http://jsfiddle.net/img/logo.png');
xhr.responseType = 'blob';
xhr.send();      

EDIT

So revisiting this topic, it seems it is indeed possible to do this with jQuery 3

I came across this really great talk by Facebook engineers about the Efficient Storage of Billions of Photos in a database

I solved my problem like this...

/**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message,
            String keys, String msgId, String branchId) {

            if (msgId != null && !msgId.equalsIgnoreCase("")) {
                if (key != null && key.equalsIgnoreCase("Yo! Matter")) {
                    ViewYoDataBase db_yo = new ViewYoDataBase(context);
                    position = db_yo.getPosition(msgId);

                        resultIntent.putExtra("notRefresh", "notRefresh");
                    } else {
                        resultIntent = new Intent(context,

            notify_no = notify_no + 1;
        } else {
            notify_no = 0;
        }
        nBuilder.setContentIntent(resultPendingIntent);
        NotificationManager nNotifyMgr = (NotificationManager) context
                .getSystemService(context.NOTIFICATION_SERVICE);
        nNotifyMgr.notify(notify_no + 2, nBuilder.build());
    }

I don't think jQuery is required here.

You can use $watch and ng-click instead

<div ng-app="myApp">
  <div ng-controller="MyCtrl">
    <input test-change ng-model="foo" />
    <span>{{foo}}</span>

    <button ng-click=" foo= 'xxx' ">click me</button>
    <!-- this changes foo value, you can also call a function from your controller -->
  </div>
</div>

In your controller :

$scope.$watch('foo', function(newValue, oldValue) {
  console.log(newValue);
  console.log(oldValue);
});

Some feedback on the segment of code, though for the most part, it should work...

void main(int c,char **args)

• int main - the standard defines main as returning an int.
• c and args are typically named argc and argv, respectfully, but you are allowed to name them anything

...

{
DIR *dir;
struct dirent *dent;
char buffer[50];
strcpy(buffer,args[1]);

• You have a buffer overflow here: If args[1] is longer than 50 bytes, buffer will not be able to hold it, and you will write to memory that you shouldn't. There's no reason I can see to copy the buffer here, so you can sidestep these issues by just not using strcpy...

...

dir=opendir(buffer);   //this part

If this returning NULL, it can be for a few reasons:

• The directory didn't exist. (Did you type it right? Did it have a space in it, and you typed ./your_program my directory, which will fail, because it tries to opendir("my"))
• You lack permissions to the directory
• There's insufficient memory. (This is unlikely.)

One statement can be written as such:

someValues.forEach(x => console.log(x));

or multiple statements can be enclosed in {} like this:

someValues.forEach(x => { let a = 2 + x; console.log(a); });

I wrote a scheduler faster than cron. I have also implemented an overlapping guard. You can configure the scheduler to not start new process if previous one is still running. Take a look at https://github.com/sioux1977/scheduler/wiki

try

driver.executeScript("window.location.href='http://www.sina.com.cn'")

this statement will return immediately.

And after that , you can add a WebDriverWait with timeout to check if the page title or any element is ok.

Hope this will help you.

I created a StackOverflow account JUST to answer this question. After fruitlessly searching the interwebs I just wrote something myself. This is how I did it so it can be applied to any mongoose model. Either import this function or add it directly into your code where you are doing the updating.

function upsertObject (src, dest) {

  function recursiveFunc (src, dest) {
    _.forOwn(src, function (value, key) {
      if(_.isObject(value) && _.keys(value).length !== 0) {
        dest[key] = dest[key] || {};
        recursiveFunc(src[key], dest[key])
      } else if (_.isArray(src) && !_.isObject(src[key])) {
          dest.set(key, value);
      } else {
        dest[key] = value;
      }
    });
  }

  recursiveFunc(src, dest);

  return dest;
}

Then to upsert a mongoose document do the following,

YourModel.upsert = function (id, newData, callBack) {
  this.findById(id, function (err, oldData) {
    if(err) {
      callBack(err);
    } else {
      upsertObject(newData, oldData).save(callBack);
    }
  });
};

This solution may require 2 DB calls however you do get the benefit of,

• Schema validation against your model because you are using .save()
• You can upsert deeply nested objects without manual enumeration in your update call, so if your model changes you do not have to worry about updating your code

Just remember that the destination object will always override the source even if the source has an existing value

Also, for arrays, if the existing object has a longer array than the one replacing it then the values at the end of the old array will remain. An easy way to upsert the entire array is to set the old array to be an empty array before the upsert if that is what you are intending on doing.

UPDATE - 01/16/2016 I added an extra condition for if there is an array of primitive values, Mongoose does not realize the array becomes updated without using the "set" function.

I've got a one liner to make HTML Tables look BootStrapped:

<table class="table table-striped table-bordered table-hover">

The theme suits other controls and it supports alternate row highlighting.

        // Example: Adding a converter to a column (C#)
        Style styleReading = new Style(typeof(TextBlock));
        Setter s = new Setter();
        s.Property = TextBlock.ForegroundProperty;
        Binding b = new Binding();
        b.RelativeSource = RelativeSource.Self;
        b.Path = new PropertyPath(TextBlock.TextProperty);
        b.Converter = new ReadingForegroundSetter();
        s.Value = b;
        styleReading.Setters.Add(s);
        col.ElementStyle = styleReading;

C++11 has another (imperfect) option:

std::array<int, 100> a;
a.fill(-1);

Use display: inline-block, though you need to wrap it inside a DIV to keep it from actually displaying inline. Tested in Safari.

<style type="text/css">
    .fieldset-auto-width {
         display: inline-block;
    }
</style>
<div>
  <fieldset class="fieldset-auto-width">
      <legend>Blah</legend>
      ...
  </fieldset>
</div>

TLDR; Pandas groupby.agg has a new, easier syntax for specifying (1) aggregations on multiple columns, and (2) multiple aggregations on a column. So, to do this for pandas >= 0.25, use

df.groupby('dummy').agg(Mean=('returns', 'mean'), Sum=('returns', 'sum'))

           Mean       Sum
dummy                    
1      0.036901  0.369012

OR

df.groupby('dummy')['returns'].agg(Mean='mean', Sum='sum')

           Mean       Sum
dummy                    
1      0.036901  0.369012

Pandas >= 0.25: Named Aggregation

Pandas has changed the behavior of GroupBy.agg in favour of a more intuitive syntax for specifying named aggregations. See the 0.25 docs section on Enhancements as well as relevant GitHub issues GH18366 and GH26512.

From the documentation,

To support column-specific aggregation with control over the output column names, pandas accepts the special syntax in GroupBy.agg(), known as “named aggregation”, where

• The keywords are the output column names
• The values are tuples whose first element is the column to select and the second element is the aggregation to apply to that column. Pandas provides the pandas.NamedAgg namedtuple with the fields ['column', 'aggfunc'] to make it clearer what the arguments are. As usual, the aggregation can be a callable or a string alias.

You can now pass a tuple via keyword arguments. The tuples follow the format of (<colName>, <aggFunc>).

import pandas as pd

pd.__version__                                                                                                                            
# '0.25.0.dev0+840.g989f912ee'

# Setup
df = pd.DataFrame({'kind': ['cat', 'dog', 'cat', 'dog'],
                   'height': [9.1, 6.0, 9.5, 34.0],
                   'weight': [7.9, 7.5, 9.9, 198.0]
})

df.groupby('kind').agg(
    max_height=('height', 'max'), min_weight=('weight', 'min'),)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

Alternatively, you can use pd.NamedAgg (essentially a namedtuple) which makes things more explicit.

df.groupby('kind').agg(
    max_height=pd.NamedAgg(column='height', aggfunc='max'), 
    min_weight=pd.NamedAgg(column='weight', aggfunc='min')
)

      max_height  min_weight
kind                        
cat          9.5         7.9
dog         34.0         7.5

It is even simpler for Series, just pass the aggfunc to a keyword argument.

df.groupby('kind')['height'].agg(max_height='max', min_height='min')    

      max_height  min_height

cat          9.5         9.1
dog         34.0         6.0       

Lastly, if your column names aren't valid python identifiers, use a dictionary with unpacking:

df.groupby('kind')['height'].agg(**{'max height': 'max', ...})

Pandas < 0.25

In more recent versions of pandas leading upto 0.24, if using a dictionary for specifying column names for the aggregation output, you will get a FutureWarning:

df.groupby('dummy').agg({'returns': {'Mean': 'mean', 'Sum': 'sum'}})
# FutureWarning: using a dict with renaming is deprecated and will be removed 
# in a future version

Using a dictionary for renaming columns is deprecated in v0.20. On more recent versions of pandas, this can be specified more simply by passing a list of tuples. If specifying the functions this way, all functions for that column need to be specified as tuples of (name, function) pairs.

df.groupby("dummy").agg({'returns': [('op1', 'sum'), ('op2', 'mean')]})

        returns          
            op1       op2
dummy                    
1      0.328953  0.032895

Or,

df.groupby("dummy")['returns'].agg([('op1', 'sum'), ('op2', 'mean')])

            op1       op2
dummy                    
1      0.328953  0.032895

>>> def mysplit(s):
...     head = s.rstrip('0123456789')

For testing purposes:

On the original machine, find the library, copy to the same directory as the executable:

$ ldconfig -p | grep libstdc
        libstdc++.so.6 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libstdc++.so.6
        libstdc++.so.6 (libc6) => /usr/lib32/libstdc++.so.6
$ cp /usr/lib/x86_64-linux-gnu/libstdc++.so.6 .

Then copy this same library to the target machine, and run the executable:

LD_LIBRARY_PATH=. ./myexecutable

Note: command above is temporary; it is not a system-wide change.

public JsonResult GetAjaxValue() 
{
  return Json("string value", JsonRequetBehaviour.Allowget); 
}

A key currently still is not required ("required" in the meaning "it will not work without"), but I think there is a good reason for the warning.

But in the documentation you may read now : "All JavaScript API applications require authentication."

I'm sure that it's planned for the future , that Javascript API Applications will not work without a key(as it has been in V2).

You better use a key when you want to be sure that your application will still work in 1 or 2 years.

Had the same problem, thanks mikej.

In WLS 10.3 this configuration can be found in Services > JTA menu, or if you click on the domain name (first item in the menu) - on the Configuration > JTA tabs.

An advantage of GC in some situations is an annoyance in others; reliance on GC encourages not thinking much about it. In theory, waits until 'idle' period or until it absolutely must, when it will steal bandwidth and cause response latency in your app.

But you don't have to 'not think about it.' Just as with everything else in multithreaded apps, when you can yield, you can yield. So for example, in .Net, it is possible to request a GC; by doing this, instead of less frequent longer running GC, you can have more frequent shorter running GC, and spread out the latency associated with this overhead.

But this defeats the primary attraction of GC which appears to be "encouraged to not have to think much about it because it is auto-mat-ic."

If you were first exposed to programming before GC became prevalent and were comfortable with malloc/free and new/delete, then it might even be the case that you find GC a little annoying and/or are distrustful(as one might be distrustful of 'optimization,' which has had a checkered history.) Many apps tolerate random latency. But for apps that don't, where random latency is less acceptable, a common reaction is to eschew GC environments and move in the direction of purely unmanaged code (or god forbid, a long dying art, assembly language.)

I had a summer student here a while back, an intern, smart kid, who was weaned on GC; he was so adament about the superiorty of GC that even when programming in unmanaged C/C++ he refused to follow the malloc/free new/delete model because, quote, "you shouldn't have to do this in a modern programming language." And you know? For tiny, short running apps, you can indeed get away with that, but not for long running performant apps.

using LINQ and Lamba, i wanted to return two field values and assign it to single entity object field;

as Name = Fname + " " + LName;

See my below code which is working as expected; hope this is useful;

Myentity objMyEntity = new Myentity
{
id = obj.Id,
Name = contxt.Vendors.Where(v => v.PQS_ID == obj.Id).Select(v=> new { contact = v.Fname + " " + v.LName}).Single().contact
}

no need to declare the 'contact'

This really works for me. source: https://code.google.com/p/android/issues/detail?id=61844#c4

An alternative: you can use a "hidden" applet element which implements this exist-check using a privileged action object and override your run method by:

File file = new File(yourPath);
return file.exists();

Another option is to get a ".pem" (public key) file for that particular server, and install it locally into the heart of your JRE's "cacerts" file (use the keytool helper application), then it will be able to download from that server without complaint, without compromising the entire SSL structure of your running JVM and enabling download from other unknown cert servers...

I've thought long and hard about this and finally ended up with the solution I'll describe below. It's a pretty big step up in complexity but if you do make this step, you'll end up with what you are really after, which is deterministic results for future requests.

Your example of an item being deleted is only the tip of the iceberg. What if you are filtering by color=blue but someone changes item colors in between requests? Fetching all items in a paged manner reliably is impossible... unless... we implement revision history.

I've implemented it and it's actually less difficult than I expected. Here's what I did:

• I created a single table changelogs with an auto-increment ID column
• My entities have an id field, but this is not the primary key
• The entities have a changeId field which is both the primary key as well as a foreign key to changelogs.
• Whenever a user creates, updates or deletes a record, the system inserts a new record in changelogs, grabs the id and assigns it to a new version of the entity, which it then inserts in the DB
• My queries select the maximum changeId (grouped by id) and self-join that to get the most recent versions of all records.
• Filters are applied to the most recent records
• A state field keeps track of whether an item is deleted
• The max changeId is returned to the client and added as a query parameter in subsequent requests
• Because only new changes are created, every single changeId represents a unique snapshot of the underlying data at the moment the change was created.
• This means that you can cache the results of requests that have the parameter changeId in them forever. The results will never expire because they will never change.
• This also opens up exciting feature such as rollback / revert, synching client cache etc. Any features that benefit from change history.

For those looking for a plain JS solution:

let el = document.querySelector("#myElementId");

// including the element's border
let width = el.offsetWidth;
let height = el.offsetHeight;

// not including the element's border:
let width = el.clientWidth;
let height = el.clientHeight;

Since nobody else has mentioned it, I found that the xdebug debugger dramatically increased the time. I served a basic "Hello World, the time is 2020-01-01T01:01:01.010101" dynamic page and used this in my httpd.conf to time the request:

LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" **%T/%D**" combined

%T is the serve time in seconds, %D is the time in microseconds. With this in my php.ini:

[XDebug]
xdebug.remote_autostart = 1
xdebug.remote_enable = 1

I was getting around 770ms response times, but with both of those set to 0 to disable them, it jumped to 160ms instantly. Running both of these brought it down to 120ms:

php artisan route:cache
php artisan config:cache

The downside being that if I made config or route changes, I would need to re-cache them, which is annoying.

As a sidenote, oddly, moving the site from my SSD to a spinning HDD provided no performance benefits, which is super odd to me, but I suppose it's maybe cached, I'm on Windows 10 with XAMPP.

Try this:

IList<String> list_string= new List<String>();
DataGridView.DataSource = list_string.Select(x => new { Value = x }).ToList();
dgvSelectedNode.Show();

I hope this helps.

Import System.Web Or call the System.Web.HttpUtility which contains it

You will need to add the reference to the DLL if it isn't there already

string TestString = "This is a <Test String>.";
string EncodedString = System.Web.HttpUtility.HtmlEncode(TestString);

An example,

 d <- data.frame(x1=rnorm(10),
                 x2=rnorm(10),
                 x3=rnorm(10))
cor(d) # get correlations (returns matrix)

function redir(data) {_x000D_
  document.getElementById('redirect').innerHTML = '<form style="display:none;" position="absolute" method="post" action="location.php"><input id="redirbtn" type="submit" name="value" value=' + data + '></form>';_x000D_
  document.getElementById('redirbtn').click();_x000D_
}

<button onclick="redir('dataToBeSent');">Next Page</button>_x000D_
<div id="redirect"></div>

You can use this method which creates a new hidden form whose "data" is sent by "post" to "location.php" when a button[Next Page] is clicked.

You can edit the generated markup and add

target = "_blank"

Those arrows are part of the Shadow DOM, which are basically DOM elements on your page which are hidden from you. If you're new to the idea, a good introductory read can be found here.

For the most part, the Shadow DOM saves us time and is good. But there are instances, like this question, where you want to modify it.

You can modify these in Webkit now with the right selectors, but this is still in the early stages of development. The Shadow DOM itself has no unified selectors yet, so the webkit selectors are proprietary (and it isn't just a matter of appending -webkit, like in other cases).

Because of this, it seems likely that Opera just hasn't gotten around to adding this yet. Finding resources about Opera Shadow DOM modifications is tough, though. A few unreliable internet sources I've found all say or suggest that Opera doesn't currently support Shadow DOM manipulation.

I spent a bit of time looking through the Opera website to see if there'd be any mention of it, along with trying to find them in Dragonfly...neither search had any luck. Because of the silence on this issue, and the developing nature of the Shadow DOM + Shadow DOM manipulation, it seems to be a safe conclusion that you just can't do it in Opera, at least for now.

Sum of total_vm is 847170 and sum of rss is 214726, these two values are counted in 4kB pages, which means when oom-killer was running, you had used 214726*4kB=858904kB physical memory and swap space.

Since your physical memory is 1GB and ~200MB was used for memory mapping, it's reasonable for invoking oom-killer when 858904kB was used.

rss for process 2603 is 181503, which means 181503*4KB=726012 rss, was equal to sum of anon-rss and file-rss.

This function will do as JohnFx suggested and allow for varied lengths on the arrays

Function mergeArrays(ByVal arr1 As Variant, ByVal arr2 As Variant) As Variant
    Dim holdarr As Variant
    Dim ub1 As Long
    Dim ub2 As Long
    Dim bi As Long
    Dim i As Long
    Dim newind As Long

        ub1 = UBound(arr1) + 1
        ub2 = UBound(arr2) + 1

        bi = IIf(ub1 >= ub2, ub1, ub2)

        ReDim holdarr(ub1 + ub2 - 1)

        For i = 0 To bi
            If i < ub1 Then
                holdarr(newind) = arr1(i)
                newind = newind + 1
            End If

            If i < ub2 Then
                holdarr(newind) = arr2(i)
                newind = newind + 1
            End If
        Next i

        mergeArrays = holdarr
End Function

If you don't have any other indexes or sorted information for your objects, then you will have to iterate until such an object is found:

next(obj for obj in objs if obj.val == 5)

This is however faster than a complete list comprehension. Compare these two:

[i for i in xrange(100000) if i == 1000][0]

next(i for i in xrange(100000) if i == 1000)

The first one needs 5.75ms, the second one 58.3µs (100 times faster because the loop 100 times shorter).

While the accepted answer is correct, I'll add a more elegant version (in my opinion):

boolean idExists = tabPane.getTabs().stream()
    .map(Tab::getId)
    .anyMatch(idToCheck::equals);

Don't neglect using Stream#map() which allows to flatten the data structure before applying the Predicate.

Just to make this absolutely clear for all:

A .MDF file is “typically” a SQL Server data file however it is important to note that it does NOT have to be.

This is because .MDF is nothing more than a recommended/preferred notation but the extension itself does not actually dictate the file type.

To illustrate this, if someone wanted to create their primary data file with an extension of .gbn they could go ahead and do so without issue.

To qualify the preferred naming conventions:

• .mdf - Primary database data file.
• .ndf - Other database data files i.e. non Primary.
• .ldf - Log data file.

Try for simple regular expression for Mobile No

[Required (ErrorMessage="Required")]

You might want to consider using console.log with the built-in "arguments" object:

console.log(arguments); // would have shown you [0] null, [1] yourResult

This will always output all of your arguments, no matter how many arguments you have.

Answer : I found this and wants to share it with you.

Sub Copier4()
   Dim x As Integer

   For x = 1 To ActiveWorkbook.Sheets.Count
      'Loop through each of the sheets in the workbook
      'by using x as the sheet index number.
      ActiveWorkbook.Sheets(x).Copy _
         After:=ActiveWorkbook.Sheets(ActiveWorkbook.Sheets.Count)
         'Puts all copies after the last existing sheet.
   Next
End Sub

But the question, can we use it with following code to rename the sheets, if yes, how can we do so?

Sub CreateSheetsFromAList()
Dim MyCell As Range, MyRange As Range
Set MyRange = Sheets("Summary").Range("A10")
Set MyRange = Range(MyRange, MyRange.End(xlDown))
For Each MyCell In MyRange
Sheets.Add After:=Sheets(Sheets.Count) 'creates a new worksheet
Sheets(Sheets.Count).Name = MyCell.Value ' renames the new worksheet
Next MyCell
End Sub

Could it be a problem with past preview versions of Android Studio ? nowadays "beta" has replaced the "preview". I try it out step by step debugging while using Memory Monitor at same time by Android Studio (Beta) 0.8.11 on OSX 10.9.5 without any problems.

The tutorial Debugging with Android Studio also helps, specially this paragraph :

To track memory allocation of objects:

1. Start your app as described in Run Your App in Debug Mode.
2. Click Android to open the Android DDMS tool window.
3. On the Android DDMS tool window, select the Devices | logcat tab.
4. Select your device from the dropdown list.
5. Select your app by its package name from the list of running apps.
6. Click Start Allocation Tracking Interact with your app on the device. Click Stop Allocation Tracking

Here a couple of screenshot while debugging step by step on a breakpoint a monitoring the memory on the emulator:

An alternative solution to that of @Aaron is the bquote() function. We need to supply a valid R expression, in this case LABEL ~ x^2 for example, where LABEL is the string you want to assign from the vector labNames. bquote evaluates R code within the expression wrapped in .( ) and subsitutes the result into the expression.

Here is an example:

labNames <- c('xLab','yLab')
xlab <- bquote(.(labNames[1]) ~ x^2)
ylab <- bquote(.(labNames[2]) ~ y^2)
plot(c(1:10), xlab = xlab, ylab = ylab)

(Note the ~ just adds a bit of spacing, if you don't want the space, replace it with * and the two parts of the expression will be juxtaposed.)

Got the same question from a friend. My suggestion which does not require !Important looks like this: I add a custom class "no-border" which can be added to the bootstrap table.

.table.no-border tr td, .table.no-border tr th {
  border-width: 0;
}

You can see my go at a solution here

Bootstrap 4 progress bar

<div class="progress">
<div class="progress-bar" role="progressbar" style="" aria-valuenow="" aria-valuemin="0" aria-valuemax="100"></div>
</div>

Javascript

change progress bar on next/previous page actions

var count = Number(document.getElementById('count').innerHTML); //set this on page load in a hidden field after an ajax call
var total = document.getElementById('total').innerHTML; //set this on initial page load
var pcg = Math.floor(count/total*100);        
document.getElementsByClassName('progress-bar').item(0).setAttribute('aria-valuenow',pcg);
document.getElementsByClassName('progress-bar').item(0).setAttribute('style','width:'+Number(pcg)+'%');

The correct solution is to take a peek at contrib/completions/git-completion.bash does that for bash prompt in __git_ps1. Removing all extras like selecting how to describe detached HEAD situation, i.e. when we are on unnamed branch, it is:

branch_name="$(git symbolic-ref HEAD 2>/dev/null)" ||
branch_name="(unnamed branch)"     # detached HEAD

branch_name=${branch_name##refs/heads/}

git symbolic-ref is used to extract fully qualified branch name from symbolic reference; we use it for HEAD, which is currently checked out branch.

Alternate solution could be:

branch_name=$(git symbolic-ref -q HEAD)
branch_name=${branch_name##refs/heads/}
branch_name=${branch_name:-HEAD}

where in last line we deal with the detached HEAD situation, using simply "HEAD" to denote such situation.

Added 11-06-2013

Junio C. Hamano (git maintainer) blog post, Checking the current branch programatically, from June 10, 2013 explains whys (and hows) in more detail.

No you cannot. The only thing you can do is to insert content. Like so:

p:after {
    content: "yo";
}

You could actually do it with javascript but remember js is client side, so you would actually be "warning users" what type of files they can upload, if you want to AVOID (restrict or limit as you said) certain type of files you MUST do it server side.

Look at this basic tut if you would like to get started with server side validation. For the whole tutorial visit this page.

Good luck!

A workaround for Android 4.x:

I found AutoResizeTextView and it works great on my Android 2.1 emulator. I loved it so much. But unfortunately it failed on my own 4.0.4 cellphone and 4.1 emulator. After trying I found it could be easily resolved by adding following attributes in AutoResizeTextView class in the xml:

android:ellipsize="none"

android:singleLine="true"

With the 2 lines above, now AutoResizeTextView working perfectly on my 2.1 & 4.1 emulators and my own 4.0.4 cellphone now.

Hope this helps you. :-)

Simply parsing the JSON and comparing the two objects is not enough because it wouldn't be the exact same object references (but might be the same values).

You need to do a deep equals.

From http://threebit.net/mail-archive/rails-spinoffs/msg06156.html - which seems the use jQuery.

Object.extend(Object, {
   deepEquals: function(o1, o2) {
     var k1 = Object.keys(o1).sort();
     var k2 = Object.keys(o2).sort();
     if (k1.length != k2.length) return false;
     return k1.zip(k2, function(keyPair) {
       if(typeof o1[keyPair[0]] == typeof o2[keyPair[1]] == "object"){
         return deepEquals(o1[keyPair[0]], o2[keyPair[1]])
       } else {
         return o1[keyPair[0]] == o2[keyPair[1]];
       }
     }).all();
   }
});

Usage:

var anObj = JSON.parse(jsonString1);
var anotherObj= JSON.parse(jsonString2);

if (Object.deepEquals(anObj, anotherObj))
   ...

You might try boost::lexical_cast. It throws an bad_lexical_cast exception if it fails.

In your case:

int number;
try
{
  number = boost::lexical_cast<int>(word);
}
catch(boost::bad_lexical_cast& e)
{
  std::cout << word << "isn't a number" << std::endl;
}

As to why atof() isn't working in the original question: the fact that it's cast to double makes me suspicious. The code shouldn't compile without #include <stdlib.h>, but if the cast was added to solve a compile warning, then atof() is not correctly declared. If the compiler assumes atof() returns an int, casting it will solve the conversion warning, but it will not cause the return value to be recognized as a double.

#include <stdlib.h>
#include <string>

... 
  std::string num = "0.6";
  double temp = atof(num.c_str());

should work without warnings.

I'm actually having a trouble with similar behaviour, I render a video element in a Component with it's id attribute so when RenderDOM.render() ends it loads a plugin that needs the id to find the placeholder and it fails to find it.

The setTimeout with 0ms inside the componentDidMount() fixed it :)

componentDidMount() {
    if (this.props.onDidMount instanceof Function) {
        setTimeout(() => {
            this.props.onDidMount();
        }, 0);
    }
}

This is what I use to display images from blob:

echo '<img src="data:image/jpeg;base64,'.base64_encode($image->load()) .'" />';

According to the Gulp docs:

Are your tasks running before the dependencies are complete? Make sure your dependency tasks are correctly using the async run hints: take in a callback or return a promise or event stream.

To run your sequence of tasks synchronously:

1. Return the event stream (e.g. gulp.src) to gulp.task to inform the task of when the stream ends.
2. Declare task dependencies in the second argument of gulp.task.

See the revised code:

gulp.task "coffee", ->
    return gulp.src("src/server/**/*.coffee")
        .pipe(coffee {bare: true}).on("error",gutil.log)
        .pipe(gulp.dest "bin")

gulp.task "clean", ['coffee'], ->
      return gulp.src("bin", {read:false})
        .pipe clean
            force:true

gulp.task 'develop',['clean','coffee'], ->
    console.log "run something else"

select type, craft, sum(NVL(regular, 0) + NVL(overtime, 0)) as total_hours
from hours_t
group by type, craft
order by type, craft

It sounds like you want to convert the rownames to a proper column of the data.frame. eg:

# add the rownames as a proper column
myDF <- cbind(Row.Names = rownames(myDF), myDF)
myDF

#           Row.Names id val vr2
# row_one     row_one  A   1  23
# row_two     row_two  A   2  24
# row_three row_three  B   3  25
# row_four   row_four  C   4  26

If you want to then remove the original rownames:

rownames(myDF) <- NULL
myDF
#   Row.Names id val vr2
# 1   row_one  A   1  23
# 2   row_two  A   2  24
# 3 row_three  B   3  25
# 4  row_four  C   4  26

Alternatively, if all of your data is of the same class (ie, all numeric, or all string), you can convert to Matrix and name the dimnames

myMat <- as.matrix(myDF)
names(dimnames(myMat)) <- c("Names.of.Rows", "")
myMat

# Names.of.Rows id  val vr2 
#   row_one   "A" "1" "23"
#   row_two   "A" "2" "24"
#   row_three "B" "3" "25"
#   row_four  "C" "4" "26"

I use the following technique. It makes it easy to keep the column names in sync with the content:

var cursor = db.getCollection('Employees.Details').find({})

var header = []

jQuery does not have a method for comparing arrays. However the Underscore library (or the comparable Lodash library) does have such a method: isEqual, and it can handle a variety of other cases (like object literals) as well. To stick to the provided example:

var a=[1,2,3];
var b=[3,2,1];
var c=new Array(1,2,3);

alert(_.isEqual(a, b) + "|" + _.isEqual(b, c));

By the way: Underscore has lots of other methods that jQuery is missing as well, so it's a great complement to jQuery.

EDIT: As has been pointed out in the comments, the above now only works if both arrays have their elements in the same order, ie.:

_.isEqual([1,2,3], [1,2,3]); // true
_.isEqual([1,2,3], [3,2,1]); // false

Fortunately Javascript has a built in method for for solving this exact problem, sort:

_.isEqual([1,2,3].sort(), [3,2,1].sort()); // true

This worked for me

<img src="data:image;base64,@System.Convert.ToBase64String(Model.CategoryPicture.Content)" width="80" height="80"/>     

I know this was already discussed to death, but I'd like to add some more points:

• Frags can be used to populate Menus and can handle MenuItem clicks on their own. Thus giving futher modulation options for your Activities. You can do ContextualActionBar stuff and so on without your Activity knowing about it and can basically decouple it from the basic stuff your Activity handles (Navigation/Settings/About).

• A parent Frag with child Frags can give you further options to modulize your components. E.g. you can easily swap Frags around, put new Frags inside a Pager or remove them, rearrange them. All without your Activity knowing anything about it just focusing on the higher level stuff.

SWT by itself is pretty low-level, and it uses the platform's native widgets through JNI. It is not related to Swing and AWT at all. The Eclipse IDE and all Eclipse-based Rich Client Applications, like the Vuze BitTorrent client, are built using SWT. Also, if you are developing Eclipse plugins, you will typically use SWT.
I have been developing Eclipse-based applications and plugins for almost 5 years now, so I'm clearly biased. However, I also have extensive experience in working with SWT and the JFace UI toolkit, which is built on top of it. I have found JFace to be very rich and powerful; in some cases it might even be the main reason for choosing SWT. It enables you to whip up a working UI quite quickly, as long as it is IDE-like (with tables, trees, native controls, etc). Of course you can integrate your custom controls as well, but that takes some extra effort.

I would go with unset because it might give the garbage collector a better hint so that the memory can be available again sooner. Be careful that any things the object points to either have other references or get unset first or you really will have to wait on the garbage collector since there would then be no handles to them.

If rm cannot remove a symlink, perhaps you need to look at the permissions on the directory that contains the symlink. To remove directory entries, you need write permission on the containing directory.

from cStringIO import StringIO # Python3 use: from io import StringIO
import sys

old_stdout = sys.stdout
sys.stdout = mystdout = StringIO()

# blah blah lots of code ...

sys.stdout = old_stdout

# examine mystdout.getvalue()

You can also use

lblExamlple.ForeColor = System.Drawing.Color.FromArgb(0,255,0);

If your file starts with the bytes 60, 118, 56, 46 and 49, then you have an ambiguous case. It could be UTF-8 (without BOM) or any of the single byte encodings like ASCII, ANSI, ISO-8859-1 etc.

I the following error message when faced this same problem:

Unfortunately, at the time of writing this answer, there is no direct way to do this. You need to:

1. use a semi-transparent image for background (much easier).
2. add an extra element (like div) next to children which you want the opaque, add background to it and after making it semi-transparent, position it behind mentioned children.

Spaceship Operator <=> (Added in PHP 7)

Examples for <=> Spaceship operator (PHP 7, Source: PHP Manual):

Integers, Floats, Strings, Arrays & objects for Three-way comparison of variables.

// Integers
echo 10 <=> 10; // 0
echo 10 <=> 20; // -1
echo 20 <=> 10; // 1

// Floats
echo 1.5 <=> 1.5; // 0
echo 1.5 <=> 2.5; // -1
echo 2.5 <=> 1.5; // 1

// Strings
echo "a" <=> "a"; // 0
echo "a" <=> "b"; // -1
echo "b" <=> "a"; // 1
// Comparison is case-sensitive
echo "B" <=> "a"; // -1

echo "a" <=> "aa"; // -1
echo "zz" <=> "aa"; // 1

// Arrays
echo [] <=> []; // 0
echo [1, 2, 3] <=> [1, 2, 3]; // 0
echo [1, 2, 3] <=> []; // 1
echo [1, 2, 3] <=> [1, 2, 1]; // 1
echo [1, 2, 3] <=> [1, 2, 4]; // -1

// Objects
$a = (object) ["a" => "b"]; 
$b = (object) ["a" => "b"]; 
echo $a <=> $b; // 0

$a = (object) ["a" => "b"]; 
$b = (object) ["a" => "c"]; 
echo $a <=> $b; // -1

$a = (object) ["a" => "c"]; 
$b = (object) ["a" => "b"]; 
echo $a <=> $b; // 1

// only values are compared
$a = (object) ["a" => "b"]; 
$b = (object) ["b" => "b"]; 
echo $a <=> $b; // 1

If targetSdkVersion is higher than 24, then FileProvider is used to grant access.

Create an xml file(Path: res\xml) provider_paths.xml

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path name="external_files" path="."/>
</paths>

Add a Provider in AndroidManifest.xml

    <provider
        android:name="android.support.v4.content.FileProvider"
        android:authorities="${applicationId}.provider"
        android:exported="false"
        android:grantUriPermissions="true">
        <meta-data
            android:name="android.support.FILE_PROVIDER_PATHS"
            android:resource="@xml/provider_paths"/>
    </provider>

If you are using androidx, the FileProvider path should be:

 android:name="androidx.core.content.FileProvider"

and replace

Uri uri = Uri.fromFile(fileImagePath);

to

Uri uri = FileProvider.getUriForFile(MainActivity.this, BuildConfig.APPLICATION_ID + ".provider",fileImagePath);

Edit: While you're including the URI with an Intent make sure to add below line:

intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);

and you are good to go. Hope it helps.

SELECT  [TABLE_NAME] ,
        [INFORMATION_SCHEMA].COLUMNS.COLUMN_NAME
FROM    INFORMATION_SCHEMA.COLUMNS
WHERE   INFORMATION_SCHEMA.COLUMNS.COLUMN_NAME LIKE '%NAME%' ;

You can set this programmatically in the controller:-

HttpContext.Current.Server.ScriptTimeout = 300;

Sets the timeout to 5 minutes instead of the default 110 seconds (what an odd default?)

The problem is that --exclude="*" says to exclude (for example) the 1260000000/ directory, so rsync never examines the contents of that directory, so never notices that the directory contains files that would have been matched by your --include.

I think the closest thing to what you want is this:

rsync -nrv --include="*/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(which will include all directories, and all files matching file_11*.jpg, but no other files), or maybe this:

rsync -nrv --include="/[0-9][0-9][0-9]0000000/" --include="file_11*.jpg" --exclude="*" /Storage/uploads/ /website/uploads/

(same concept, but much pickier about the directories it will include).

I was searching for a simple solution without window focus. Jayk's answer, pynput, works perfect for me. Here is the example how I use it.

from pynput import keyboard

def on_press(key):
    if key == keyboard.Key.esc:
        return False  # stop listener
    try:
        k = key.char  # single-char keys
    except:
        k = key.name  # other keys
    if k in ['1', '2', 'left', 'right']:  # keys of interest
        # self.keys.append(k)  # store it in global-like variable
        print('Key pressed: ' + k)
        return False  # stop listener; remove this if want more keys

listener = keyboard.Listener(on_press=on_press)
listener.start()  # start to listen on a separate thread
listener.join()  # remove if main thread is polling self.keys

Popen.communicate will set the returncode attribute when it's done(*). Here's the relevant documentation section:

Popen.returncode 
  The child return code, set by poll() and wait() (and indirectly by communicate()). 
  A None value indicates that the process hasn’t terminated yet.

  A negative value -N indicates that the child was terminated by signal N (Unix only).

So you can just do (I didn't test it but it should work):

import subprocess as sp
child = sp.Popen(openRTSP + opts.split(), stdout=sp.PIPE)
streamdata = child.communicate()[0]
rc = child.returncode

(*) This happens because of the way it's implemented: after setting up threads to read the child's streams, it just calls wait.

Sure. On my (pretty vanilla) Cygwin setup, bash is in c:\cygwin\bin so I can run a bash script (say testit.sh) from a Windows batch file using a command like:

C:\cygwin\bin\bash testit.sh

... which can be included in a .bat file as easily as it can be typed at the command line, and with the same effect.

Have a look at the Date class. There's also the newer Calendar class which is the preferred method of doing many date / time operations (a lot of the methods on Date have been deprecated.)

If you just want the current date, then either create a new Date object or call Calendar.getInstance();.

Beside the methods described in previous answers, you can also use a free execution plan viewer and query optimization tool ApexSQL Plan (which I’ve recently bumped into).

You can install and integrate ApexSQL Plan into SQL Server Management Studio, so execution plans can be viewed from SSMS directly.

Viewing Estimated execution plans in ApexSQL Plan

1. Click the New Query button in SSMS and paste the query text in the query text window. Right click and select the “Display Estimated Execution Plan” option from the context menu.

2. The execution plan diagrams will be shown the Execution Plan tab in the results section. Next right-click the execution plan and in the context menu select the “Open in ApexSQL Plan” option.

3. The Estimated execution plan will be opened in ApexSQL Plan and it can be analyzed for query optimization.

Viewing Actual execution plans in ApexSQL Plan

To view the Actual execution plan of a query, continue from the 2nd step mentioned previously, but now, once the Estimated plan is shown, click the “Actual” button from the main ribbon bar in ApexSQL Plan.

Once the “Actual” button is clicked, the Actual execution plan will be shown with detailed preview of the cost parameters along with other execution plan data.

More information about viewing execution plans can be found by following this link.

As a more general answer http://sourceforge.net/p/predef/wiki/Home/ maintains a list of macros for detecting specicic compilers, operating systems, architectures, standards and more.

If you're in Rails, .blank? should be the method you are looking for:

a = nil
b = []
c = ""

a.blank? #=> true
b.blank? #=> true
c.blank? #=> true

d = "1"
e = ["1"]

d.blank? #=> false
e.blank? #=> false

So the answer would be:

variable = id if variable.blank?

Arrays

• Set, Check element at a particular index: O(1)
• Searching: O(n) if array is unsorted and O(log n) if array is sorted and something like a binary search is used,
• As pointed out by Aivean, there is no Delete operation available on Arrays. We can symbolically delete an element by setting it to some specific value, e.g. -1, 0, etc. depending on our requirements
• Similarly, Insert for arrays is basically Set as mentioned in the beginning

ArrayList:

• Add: Amortized O(1)
• Remove: O(n)
• Contains: O(n)
• Size: O(1)

Linked List:

• Inserting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Doubly-Linked List:

• Inserting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Deleting: O(1), if done at the head or tail, O(n) if anywhere else since we have to reach that position by traveseing the linkedlist linearly.
• Searching: O(n)

Stack:

• Push: O(1)
• Pop: O(1)
• Top: O(1)
• Search (Something like lookup, as a special operation): O(n) (I guess so)

Queue/Deque/Circular Queue:

• Insert: O(1)
• Remove: O(1)
• Size: O(1)

Binary Search Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(n)

Red-Black Tree:

• Insert, delete and search: Average case: O(log n), Worst Case: O(log n)

Heap/PriorityQueue (min/max):

• Find Min/Find Max: O(1)
• Insert: O(log n)
• Delete Min/Delete Max: O(log n)
• Extract Min/Extract Max: O(log n)
• Lookup, Delete (if at all provided): O(n), we will have to scan all the elements as they are not ordered like BST

HashMap/Hashtable/HashSet:

• Insert/Delete: O(1) amortized
• Re-size/hash: O(n)
• Contains: O(1)

The problem is that the checkout takes place on a laptop and in this case subversion can not cope with the off-line synchronization. The problem is reproducable on an other laptop while on a desktop I have no problem checking out the same repository.

I hope this answer wil help you, it took me quite long to find out.

Have you tried switching over to WebInvokeAttribute and setting the Method to "GET"?

I believe I had a similar problem and switched to explicitly telling which Method (GET/PUT/POST/DELETE) is expected on most, if not all, my methods.

public class SomeController : ApiController
{
    [WebInvoke(UriTemplate = "{itemSource}/Items"), Method="GET"]
    public SomeValue GetItems(CustomParam parameter) { ... }

    [WebInvoke(UriTemplate = "{itemSource}/Items/{parent}", Method = "GET")]
    public SomeValue GetChildItems(CustomParam parameter, SomeObject parent) { ... }
}

The WebGet should handle it but I've seen it have some issues with multiple Get much less multiple Get of the same return type.

[Edit: none of this is valid with the sunset of WCF WebAPI and the migration to ASP.Net WebAPI on the MVC stack]

First()

When you know that result contain more than 1 element expected and you should only the first element of sequence.

FirstOrDefault()

FirstOrDefault() is just like First() except that, if no element match the specified condition than it returns default value of underlying type of generic collection. It does not throw InvalidOperationException if no element found. But collection of element or a sequence is null than it throws an exception.

None of these answers solved my problem, which was that the items weren't the same width in my makeshift flexbox table when it was shrunk to a width too small.

The solution for me was simply to put overflow: hidden; on the flex-grow: 1; cells.

you can show the file selection dialog with a onclick function, and if a file is choosen (onchange event) then send the form to upload the file

 <form id='foto' method='post' action='upload' method="POST"  enctype="multipart/form-data" >
  <div style="height:0px;overflow:hidden"> 
  <input type="file" id="fileInput" name="fileInput" onchange="this.form.submit()"/> 
  </div>

  <i class='fa fa-camera' onclick="fileInput.click();"></i>
</form> 

You can simply add show.legend=FALSE to geom to suppress the corresponding legend

SELECT * FROM tablename
WHERE CAST(FLOOR(CAST(column_datetime AS FLOAT))AS DATETIME) = '30 jan 2012'

The last (third to be exactly) RFC for this issue is RFC-6265 (Obsoletes RFC-2965 that in turn obsoletes RFC-2109).

According to it if the server omits the Domain attribute, the user agent will return the cookie only to the origin server (the server on which a given resource resides). But it's also warning that some existing user agents treat an absent Domain attribute as if the Domain attribute were present and contained the current host name (For example, if example.com returns a Set-Cookie header without a Domain attribute, these user agents will erroneously send the cookie to www.example.com as well).

When the Domain attribute have been specified, it will be treated as complete domain name (if there is the leading dot in attribute it will be ignored). Server should match the domain specified in attribute (have exactly the same domain name or to be a subdomain of it) to get this cookie. More accurately it specified here.

So, for example:

• cookie attribute Domain=.example.com is equivalent to Domain=example.com
• cookies with such Domain attributes will be available for example.com and www.example.com
• cookies with such Domain attributes will be not available for another-example.com
• specifying cookie attribute like Domain=www.example.com will close the way for www4.example.com

PS: trailing comma in Domain attribute will cause the user agent to ignore the attribute =(

This doesn't direcly answer your question, but if you are using innerHTML in order to write text within an element and you ran into encoding issues, just use textContent, i.e.:

var s = "Foo 'bar' baz <qux>";

var element = document.getElementById('foo');
element.textContent = s;

// <div id="foo">Foo 'bar' baz <qux></div>

I'm using the first approach but a bit different that allows to address the problems you mentioned.

Everything that is needed to run tests for DAOs is in source control. It includes schema and scripts to create the DB (docker is very good for this). If the embedded DB can be used - I use it for speed.

The important difference with the other described approaches is that the data that is required for test is not loaded from SQL scripts or XML files. Everything (except some dictionary data that is effectively constant) is created by application using utility functions/classes.

The main purpose is to make data used by test

1. very close to the test
2. explicit (using SQL files for data make it very problematic to see what piece of data is used by what test)
3. isolate tests from the unrelated changes.

It basically means that these utilities allow to declaratively specify only things essential for the test in test itself and omit irrelevant things.

To give some idea of what it means in practice, consider the test for some DAO which works with Comments to Posts written by Authors. In order to test CRUD operations for such DAO some data should be created in the DB. The test would look like:

@Test
public void savedCommentCanBeRead() {
    // Builder is needed to declaratively specify the entity with all attributes relevant
    // for this specific test
    // Missing attributes are generated with reasonable values
    // factory's responsibility is to create entity (and all entities required by it
    //  in our example Author) in the DB
    Post post = factory.create(PostBuilder.post());

    Comment comment = CommentBuilder.comment().forPost(post).build();

    sut.save(comment);

    Comment savedComment = sut.get(comment.getId());

    // this checks fields that are directly stored
    assertThat(saveComment, fieldwiseEqualTo(comment));
    // if there are some fields that are generated during save check them separately
    assertThat(saveComment.getGeneratedField(), equalTo(expectedValue));        
}

This has several advantages over SQL scripts or XML files with test data:

1. Maintaining the code is much easier (adding a mandatory column for example in some entity that is referenced in many tests, like Author, does not require to change lots of files/records but only a change in builder and/or factory)
2. The data required by specific test is described in the test itself and not in some other file. This proximity is very important for test comprehensibility.

Rollback vs Commit

I find it more convenient that tests do commit when they are executed. Firstly, some effects (for example DEFERRED CONSTRAINTS) cannot be checked if commit never happens. Secondly, when a test fails the data can be examined in the DB as it is not reverted by the rollback.

Of cause this has a downside that test may produce a broken data and this will lead to the failures in other tests. To deal with this I try to isolate the tests. In the example above every test may create new Author and all other entities are created related to it so collisions are rare. To deal with the remaining invariants that can be potentially broken but cannot be expressed as a DB level constraint I use some programmatic checks for erroneous conditions that may be run after every single test (and they are run in CI but usually switched off locally for performance reasons).

try this

 data => {
                this.results = [...this.results, ...data.results];
                this._next = data.next;
            }

Try this. I am sure you do not need a back button image to create one such.

UIBarButtonItem *backButton = [[UIBarButtonItem alloc] initWithTitle:@"Back"
                                                               style:UIBarButtonItemStyleBordered
                                                              target:self
                                                              action:@selector(yourSelectorGoesHere:)];
self.navigationItem.backBarButtonItem = backButton;

That's all you have to do :)

This is not exactly a hot topic, but I have a factory class that allows a dll to create an instance and return it as a DLL. It is what I came looking for but couldn't find exactly.

It is called like,

IHTTP_Server *server = SN::SN_Factory<IHTTP_Server>::CreateObject();
IHTTP_Server *server2 =
      SN::SN_Factory<IHTTP_Server>::CreateObject(IHTTP_Server_special_entry);

where IHTTP_Server is the pure virtual interface for a class created either in another DLL, or the same one.

DEFINE_INTERFACE is used to give a class id an interface. Place inside interface;

An interface class looks like,

class IMyInterface
{
    DEFINE_INTERFACE(IMyInterface);

public:
    virtual ~IMyInterface() {};

    virtual void MyMethod1() = 0;
    ...
};

The header file is like this

#if !defined(SN_FACTORY_H_INCLUDED)
#define SN_FACTORY_H_INCLUDED

#pragma once

The libraries are listed in this macro definition. One line per library/executable. It would be cool if we could call into another executable.

#define SN_APPLY_LIBRARIES(L, A)                          \
    L(A, sn, "sn.dll")                                    \
    L(A, http_server_lib, "http_server_lib.dll")          \
    L(A, http_server, "")

Then for each dll/exe you define a macro and list its implementations. Def means that it is the default implementation for the interface. If it is not the default, you give a name for the interface used to identify it. Ie, special, and the name will be IHTTP_Server_special_entry.

#define SN_APPLY_ENTRYPOINTS_sn(M)                                     \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, def)                   \
    M(IHTTP_Handler, SNI::SNI_HTTP_Handler, sn, special)

#define SN_APPLY_ENTRYPOINTS_http_server_lib(M)                        \
    M(IHTTP_Server, HTTP::server::server, http_server_lib, def)

#define SN_APPLY_ENTRYPOINTS_http_server(M)

With the libraries all setup, the header file uses the macro definitions to define the needful.

#define APPLY_ENTRY(A, N, L) \
    SN_APPLY_ENTRYPOINTS_##N(A)

#define DEFINE_INTERFACE(I) \
    public: \
        static const long Id = SN::I##_def_entry; \
    private:

namespace SN
{
    #define DEFINE_LIBRARY_ENUM(A, N, L) \
        N##_library,

This creates an enum for the libraries.

    enum LibraryValues
    {
        SN_APPLY_LIBRARIES(DEFINE_LIBRARY_ENUM, "")
        LastLibrary
    };

    #define DEFINE_ENTRY_ENUM(I, C, L, D) \
        I##_##D##_entry,

This creates an enum for interface implementations.

    enum EntryValues
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_ENUM)
        LastEntry
    };

    long CallEntryPoint(long id, long interfaceId);

This defines the factory class. Not much to it here.

    template <class I>
    class SN_Factory
    {
    public:
        SN_Factory()
        {
        }

        static I *CreateObject(long id = I::Id )
        {
            return (I *)CallEntryPoint(id, I::Id);
        }
    };
}

#endif //SN_FACTORY_H_INCLUDED

Then the CPP is,

#include "sn_factory.h"

#include <windows.h>

Create the external entry point. You can check that it exists using depends.exe.

extern "C"
{
    __declspec(dllexport) long entrypoint(long id)
    {
        #define CREATE_OBJECT(I, C, L, D) \
            case SN::I##_##D##_entry: return (int) new C();

        switch (id)
        {
            SN_APPLY_CURRENT_LIBRARY(APPLY_ENTRY, CREATE_OBJECT)
        case -1:
        default:
            return 0;
        }
    }
}

The macros set up all the data needed.

namespace SN
{
    bool loaded = false;

    char * libraryPathArray[SN::LastLibrary];
    #define DEFINE_LIBRARY_PATH(A, N, L) \
        libraryPathArray[N##_library] = L;

    static void LoadLibraryPaths()
    {
        SN_APPLY_LIBRARIES(DEFINE_LIBRARY_PATH, "")
    }

    typedef long(*f_entrypoint)(long id);

    f_entrypoint libraryFunctionArray[LastLibrary - 1];
    void InitlibraryFunctionArray()
    {
        for (long j = 0; j < LastLibrary; j++)
        {
            libraryFunctionArray[j] = 0;
        }

        #define DEFAULT_LIBRARY_ENTRY(A, N, L) \
            libraryFunctionArray[N##_library] = &entrypoint;

        SN_APPLY_CURRENT_LIBRARY(DEFAULT_LIBRARY_ENTRY, "")
    }

    enum SN::LibraryValues libraryForEntryPointArray[SN::LastEntry];
    #define DEFINE_ENTRY_POINT_LIBRARY(I, C, L, D) \
            libraryForEntryPointArray[I##_##D##_entry] = L##_library;
    void LoadLibraryForEntryPointArray()
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_POINT_LIBRARY)
    }

    enum SN::EntryValues defaultEntryArray[SN::LastEntry];
        #define DEFINE_ENTRY_DEFAULT(I, C, L, D) \
            defaultEntryArray[I##_##D##_entry] = I##_def_entry;

    void LoadDefaultEntries()
    {
        SN_APPLY_LIBRARIES(APPLY_ENTRY, DEFINE_ENTRY_DEFAULT)
    }

    void Initialize()
    {
        if (!loaded)
        {
            loaded = true;
            LoadLibraryPaths();
            InitlibraryFunctionArray();
            LoadLibraryForEntryPointArray();
            LoadDefaultEntries();
        }
    }

    long CallEntryPoint(long id, long interfaceId)
    {
        Initialize();

        // assert(defaultEntryArray[id] == interfaceId, "Request to create an object for the wrong interface.")
        enum SN::LibraryValues l = libraryForEntryPointArray[id];

        f_entrypoint f = libraryFunctionArray[l];
        if (!f)
        {
            HINSTANCE hGetProcIDDLL = LoadLibraryA(libraryPathArray[l]);

            if (!hGetProcIDDLL) {
                return NULL;
            }

            // resolve function address here
            f = (f_entrypoint)GetProcAddress(hGetProcIDDLL, "entrypoint");
            if (!f) {
                return NULL;
            }
            libraryFunctionArray[l] = f;
        }
        return f(id);
    }
}

Each library includes this "cpp" with a stub cpp for each library/executable. Any specific compiled header stuff.

#include "sn_pch.h"

Setup this library.

#define SN_APPLY_CURRENT_LIBRARY(L, A) \
    L(A, sn, "sn.dll")

An include for the main cpp. I guess this cpp could be a .h. But there are different ways you could do this. This approach worked for me.

#include "../inc/sn_factory.cpp"
