There is a bunch on here:

http://www.webservicex.net/WS/wscatlist.aspx

Just google for "Free WebService" or "Open WebService" and you'll find tons of open SOAP endpoints.

Remember, you can get a WSDL from any ASMX endpoint by adding ?WSDL to the url.

I'd like to add the following to Shay Levy's correct answer: You can make your life easier if you create a little batch script run.cmd to launch your powershell script:

@echo off & setlocal
set batchPath=%~dp0
powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" "MY-PC"

Put it in the same path as SQLExecutor.ps1 and from now on you can run it by simply double-clicking on run.cmd.

Note:

• If you require command line arguments inside the run.cmd batch, simply pass them as %1 ... %9 (or use %* to pass all parameters) to the powershell script, i.e.
  powershell.exe -noexit -file "%batchPath%SQLExecutor.ps1" %*

• The variable batchPath contains the executing path of the batch file itself (this is what the expression %~dp0 is used for). So you just put the powershell script in the same path as the calling batch file.

Instead of

this.$axios.get('items')

use

this.$axios({ url: 'items', baseURL: 'http://new-url.com' })

If you don't pass method: 'XXX' then by default, it will send via get method.

I can't imagine that anyone else reading this is a stupid as I was but just in case... I had accidentally removed "laravel/framework": "^5.6" from my composer.json when resolving merge conflicts.

In Expression Language you can just use the == or eq operator to compare object values. Behind the scenes they will actually use the Object#equals(). This way is done so, because until with the current EL 2.1 version you cannot invoke methods with other signatures than standard getter (and setter) methods (in the upcoming EL 2.2 it would be possible).

So the particular line

<c:when test="${lang}.equals(${pageLang})">

should be written as (note that the whole expression is inside the { and })

<c:when test="${lang == pageLang}">

or, equivalently

<c:when test="${lang eq pageLang}">

Both are behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals(jspContext.findAttribute("pageLang"))

If you want to compare constant String values, then you need to quote it

<c:when test="${lang == 'en'}">

or, equivalently

<c:when test="${lang eq 'en'}">

which is behind the scenes roughly interpreted as

jspContext.findAttribute("lang").equals("en")

I use

$location.search('key', null)

As this not only deletes my key but removes it from the visibility on the URL.

<?= $a ?> is the same as <? echo $a; ?>, just shorthand for convenience.

I'd prefer mapping after making sure the value is available

private String getStringIfObjectIsPresent(Optional<Object> object) {
   Object ob = object.orElseThrow(MyCustomException::new);
    // do your mapping with ob
   String result = your-map-function(ob);
  return result;
}

or one liner

private String getStringIfObjectIsPresent(Optional<Object> object) {
   return your-map-function(object.orElseThrow(MyCustomException::new));
}

Controller

public ActionResult Index()
    {


        //you don't need to include the category bc it does it by itself
        //var model = db.Product.Include(c => c.Category).ToList()

        ViewBag.Categories = db.Category.OrderBy(c => c.Name).ToList();
        var model = db.Product.ToList()
        return View(model);
    }

View

you need to filter the model with the given category

like :=> Model.where(p=>p.CategoryID == category.CategoryID)

try this...

@foreach (var category in ViewBag.Categories)
{
    <h3><u>@category.Name</u></h3>

    <div>

        @foreach (var product in Model.where(p=>p.CategoryID == category.CategoryID))
        {

                <table cellpadding="5" cellspacing"5" style="border:1px solid black; width:100%;background-color:White;">
                    <thead>
                        <tr>
                            <th style="background-color:black; color:white;">
                                @product.Title  
                                @if (System.Web.Security.UrlAuthorizationModule.CheckUrlAccessForPrincipal("/admin", User, "GET"))
                                {
                                    @Html.Raw(" - ")  
                                    @Html.ActionLink("Edit", "Edit", new { id = product.ID }, new { style = "background-color:black; color:white !important;" })
                                }
                            </th>
                        </tr>
                    </thead>

                    <tbody>
                        <tr>
                            <td style="background-color:White;">
                                @product.Description
                            </td>
                        </tr>
                    </tbody>      
                </table>                       
            }


    </div>
}  

add a second target for the UIButton for UIControlEventTouched and change the UIButton background color. Then change it back in the UIControlEventTouchUpInside target;

The easier (and more awesome) way to add dependencies to your package.json is to do so from the command line, flagging the npm install command with either --save or --save-dev, depending on how you'd like to use that dependency.

It might be clear for most, but have in mind that a function called inside the function component's body, acts as a beforeRender. This doesn't answer the question of running code on ComponentWillMount (before the first render) but since it is related and might help others I'm leaving it here.

const MyComponent = () => {
  const [counter, setCounter] = useState(0)
  
  useEffect(() => {
    console.log('after render')
  })

  const iterate = () => {
    setCounter(prevCounter => prevCounter+1)
  }

  const beforeRender = () => {
    console.log('before render')
  }

  beforeRender()

  return (
    <div>
      <div>{counter}</div>
      <button onClick={iterate}>Re-render</button>
    </div>
  )
}

export default MyComponent

You can fix this problem by adding "$(ProjectDir)" (or wherever the stdafx.h is) to list of directories under Project->Properties->Configuration Properties->C/C++->General->Additional Include Directories.

UPDATE : check Peter's answer below for a builtin solution :

This is a helper to set a persistent cookie:

import datetime

def set_cookie(response, key, value, days_expire=7):
    if days_expire is None:
        max_age = 365 * 24 * 60 * 60  # one year
    else:
        max_age = days_expire * 24 * 60 * 60
    expires = datetime.datetime.strftime(
        datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age),
        "%a, %d-%b-%Y %H:%M:%S GMT",
    )
    response.set_cookie(
        key,
        value,
        max_age=max_age,
        expires=expires,
        domain=settings.SESSION_COOKIE_DOMAIN,
        secure=settings.SESSION_COOKIE_SECURE or None,
    )

Use the following code before sending a response.

def view(request):
    response = HttpResponse("hello")
    set_cookie(response, 'name', 'jujule')
    return response

UPDATE : check Peter's answer below for a builtin solution :

There is a simple solution for you called unique_together which does exactly what you want.

For example:

class MyModel(models.Model):
  field1 = models.CharField(max_length=50)
  field2 = models.CharField(max_length=50)

  class Meta:
    unique_together = ('field1', 'field2',)

And in your case:

class Volume(models.Model):
  id = models.AutoField(primary_key=True)
  journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
  volume_number = models.CharField('Volume Number', max_length=100)
  comments = models.TextField('Comments', max_length=4000, blank=True)

  class Meta:
    unique_together = ('journal_id', 'volume_number',)

1. Open design view
2. Right click to textArea
3. open surround with option
4. select "...JScrollPane".

JavaScript not being strong type. It allows you to resolve problems in many different ways, as it seem in this question.

However, for a maintainability point of view, I would have to agree with Bart Hofland. A function should get arguments to do something with and return the result. Making them easily reusable.

If you feel that variables need to be passed by reference, you may be better served building them into objects, IMHO.

Try this code:

<select name="wgtmsr" id="wgtmsr">
<option value="kg">Kg</option>
<option value="gm">Gm</option>
<option value="pound">Pound</option>
<option value="MetricTon">Metric ton</option>
<option value="litre">Litre</option>
<option value="ounce">Ounce</option>
</select>

CSS:

#wgtmsr{
 width:150px;   
}

If you want to change the width of the option you can do this in your css:

#wgtmsr option{
  width:150px;   
}

Maybe you have a conflict in your css rules that override the width of your select

DEMO

My approach was slightly different, change the button into submit button and then click

$("#submit").click(function (event) {
  $(this).attr("type", "submit");
  $(this).click();
});

if still item not removed use this magic method :)

private void deleteItem(int position) {
        mDataSet.remove(position);
        notifyItemRemoved(position);
        notifyItemRangeChanged(position, mDataSet.size());
        holder.itemView.setVisibility(View.GONE);
}

Kotlin version

private fun deleteItem(position: Int) {
    mDataSet.removeAt(position)
    notifyItemRemoved(position)
    notifyItemRangeChanged(position, mDataSet.size)
    holder.itemView.visibility = View.GONE
}

const int is identical to int const, as is true with all scalar types in C. In general, declaring a scalar function parameter as const is not needed, since C's call-by-value semantics mean that any changes to the variable are local to its enclosing function.

I've not noticed any difference in startup time between the 2, but clocked a very minimal improvement in application performance with "-server" (Solaris server, everyone using SunRays to run the app). That was under 1.5.

I found the same error re occurring even after I tried all the above solutions given above. I had even tried version 5.7 and few more. Guys don't waste your time trying to fix it. Rather install version 5.5. It's working perfectly fine without any unnecessary error.

Perhaps you could try passing location into the component as a prop. Below I use ...otherProps. This is the spread operator, and is valid but unneccessary if you passed in your props explicitly it's just there as a place holder for demonstration purposes. Also, research destructuring to understand where ({ location }) came from.

import React from 'react';
import withRouter from 'react-router-dom';

const MyComponent = ({ location, ...otherProps }) => (whatever you want to render)


export withRouter(MyComponent);

I really don't know how but the bug gone after I done all this:

1

delete implementation 'com.google.android.gms:play-services:12.0.1'

And add

implementation 'com.google.android.gms:play-services-location:12.0.1'
implementation 'com.google.android.gms:play-services-maps:12.0.1'
implementation 'com.google.android.gms:play-services-places:12.0.1'

Update git, jdk, change JDK location in Project structure

3

Delete the build folder in my Project

4

Clean and rebuild the Project

Here is a CoffeeScript solution.

I was looking for the same solution and found seomething very intersting from this answer: Rejecting promises with multiple arguments (like $http) in AngularJS

the answer of this guy Florian

promise = deferred.promise

promise.success = (fn) ->
  promise.then (data) ->
   fn(data.payload, data.status, {additional: 42})
  return promise

promise.error = (fn) ->
  promise.then null, (err) ->
    fn(err)
  return promise

return promise 

And to use it:

service.get().success (arg1, arg2, arg3) ->
    # => arg1 is data.payload, arg2 is data.status, arg3 is the additional object
service.get().error (err) ->
    # => err

Just define an empty navbar prior to the fixed one, it will create the space needed.

<nav class="navbar navbar-default ">
</nav>
<nav class="navbar  navbar-default navbar-fixed-top ">
     <div class="container-fluid">
// Your menu code 
     </div>
</nav>

No, you cannot do that with CSS. That is the reason Microsoft initially introduced another, and maybe more practical box model. The box model that eventually won, makes it inpractical to mix percentages and units.

I don't think it is OK with you to express padding and border widths in percentage of the parent too.

You can use simple color resources, specified usually inside res/values/colors.xml.

<color name="red">#ffff0000</color>

and use this via android:background="@color/red". This color can be used anywhere else too, e.g. as a text color. Reference it in XML the same way, or get it in code via getResources().getColor(R.color.red).

You can also use any drawable resource as a background, use android:background="@drawable/mydrawable" for this (that means 9patch drawables, normal bitmaps, shape drawables, ..).

Was having this issue testing long doubles, and alas, I came across a fix! You have to compile your project with -D__USE_MINGW_ANSI_STDIO:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=0.000000

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ gcc main.c -D__USE_MINGW_ANSI_STDIO

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test $ a.exe c=42.000000

Code:

Jason Huntley@centurian /home/developer/dependencies/Python-2.7.3/test
$ cat main.c
#include <stdio.h>

int main(int argc, char **argv)
{
   long double c=42;

   c/3;

   printf("c=%Lf\n",c);

   return 0;
}

int main()
{
    char input[100];
    gets(input);

    char str[101];
    strcpy(str, " ");
    strcat(str, input);

    char *p = str;

    while(*p) {
       if(*p == ' ' && isalpha(*(p+1)) != 0)
           printf("%c",*(p+1));
       p++;
    }

    return 0;
}

The difference between them is that they use different pins. Seriously, that's it. The reason they both exist is that RTS/CTS wasn't supposed to ever be a flow control mechanism, originally; it was for half-duplex modems to coordinate who was sending and who was receiving. RTS and CTS got misused for flow control so often that it became standard.

For MySQL, there is none: MySQL Feature Request.

Allowing this is arguably a really bad idea, anyway: IF EXISTS indicates that you're running destructive operations on a database with (to you) unknown structure. There may be situations where this is acceptable for quick-and-dirty local work, but if you're tempted to run such a statement against production data (in a migration etc.), you're playing with fire.

But if you insist, it's not difficult to simply check for existence first in the client, or to catch the error.

MariaDB also supports the following starting with 10.0.2:

DROP [COLUMN] [IF EXISTS] col_name 

i. e.

ALTER TABLE my_table DROP IF EXISTS my_column;

But it's arguably a bad idea to rely on a non-standard feature supported by only one of several forks of MySQL.

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

The way I do it is by launching a thread to download the images in the background and hand it a callback for each list item. When an image is finished downloading it calls the callback which updates the view for the list item.

This method doesn't work very well when you're recycling views however.

Since mysql 5.6, there is a new default that makes sure you are explicitly inserting every field that doesn't have a default value set in the table definition.

to disable and test this: see this answer here: mysql error 1364 Field doesn't have a default values

I would recommend you test without it, then reenable it and make sure all your tables have default values for fields you are not explicitly passing in every INSERT query.

If a third party mysql viewer is giving this error, you are probably limited to the fix in that link.

As long as you are using CREATE TABLE, if you are creating the primary key on a single field, you can use:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER PRIMARY KEY,
field3 BLOB,
);

With CREATE TABLE, you can also always use the following approach to create a primary key on one or multiple fields:

CREATE TABLE mytable (
field1 TEXT,
field2 INTEGER,
field3 BLOB,
PRIMARY KEY (field2, field1)
);

Reference: http://www.sqlite.org/lang_createtable.html

This answer does not address table alteration.

Here is my solution (java 1.6), also would be interested why I had to do this:

I noticed from the javax.security.debug=ssl, that sometimes the used cipher suite is TLS_DHE_... and sometime it is TLS_ECDHE_.... The later would happen if I added BouncyCastle. If TLS_ECDHE_ was selected, MOST OF the time it worked, but not ALWAYS, so adding even BouncyCastle provider was unreliable (failed with same error, every other time or so). I guess somewhere in the Sun SSL implementation sometimes it choose DHE, sometimes it choose ECDHE.

So the solution posted here relies on removing TLS_DHE_ ciphers completely. NOTE: BouncyCastle is NOT required for the solution.

So create the server certification file by:

echo |openssl s_client -connect example.org:443 2>&1 |sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

Save this as it will be referenced later, than here is the solution for an SSL http get, excluding the TLS_DHE_ cipher suites.

Finally here is how it is used (certFilePath if the path of the certificate saved from openssl):

try {
            URL url = new URL("https://www.example.org?q=somedata");            
            SSLExcludeCipherConnectionHelper sslExclHelper = new SSLExcludeCipherConnectionHelper(certFilePath);
            logger.debug(
                    sslExclHelper.get(url)
            );
        } catch (Exception ex) {
            ex.printStackTrace();
        }

This solution works perfectly for bottom bar based fragment navigation when you want to close the app when back pressed in primary fragment.

On the other hand when you are opening the secondary fragment (fragment in fragment) which is defined as "DetailedPizza" in my code it will return the previous state of primary fragment. Cheers !

Inside activities on back pressed put this:

Fragment home = getSupportFragmentManager().findFragmentByTag("DetailedPizza");

if (home instanceof FragmentDetailedPizza && home.isVisible()) {
    if (getFragmentManager().getBackStackEntryCount() != 0) {
        getFragmentManager().popBackStack();
    } else {
        super.onBackPressed();
    }
} else {
    //Primary fragment
    moveTaskToBack(true);
}

And launch the other fragment like this:

Fragment someFragment = new FragmentDetailedPizza();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
transaction.replace(R.id.container_body, someFragment, "DetailedPizza");
transaction.addToBackStack("DetailedPizza");
transaction.commit();

Solution for Swift 2:

let singleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleSingleTap))
singleTapGesture.numberOfTapsRequired = 1 // Optional for single tap
view.addGestureRecognizer(singleTapGesture)

let doubleTapGesture = UITapGestureRecognizer(target: self, action: #selector(handleDoubleTap))
doubleTapGesture.numberOfTapsRequired = 2
view.addGestureRecognizer(doubleTapGesture)

singleTapGesture.requireGestureRecognizerToFail(doubleTapGesture)

It complains because it needs to use ssh instead of https but your git is still configured with https. so basically as others mentioned previously you need to either enable prompts or to configure git to use ssh instead of https. a simple way to do this by running the following:

git config --global --add url."[email protected]:".insteadOf "https://github.com/"

or if you already use ssh with git in your machine, you can safely edit ~/.gitconfig and add the following line at the very bottom

Note: This covers all SVC, source version control, that depends on what you exactly use, github, gitlab, bitbucket)

# Enforce SSH
[url "ssh://[email protected]/"]
  insteadOf = https://github.com/
[url "ssh://[email protected]/"]
        insteadOf = https://gitlab.com/
[url "ssh://[email protected]/"]
  insteadOf = https://bitbucket.org/

• If you want to keep password pompts disabled, you need to cache password. For more information on how to cache your github password on mac, windows or linux, please visit this page.

• For more information on how to add ssh to your github account, please visit this page.

Also, more importantly, if this is a private repository for a company or for your self, you may need to skip using proxy or checksum database for such repos to avoid exposing them publicly.

To do this, you need to set GOPRIVATE environment variable that controls which modules the go command considers to be private (not available publicly) and should therefore NOT use the proxy or checksum database.

The variable is a comma-separated list of patterns (same syntax of Go's path.Match) of module path prefixes. For example,

export GOPRIVATE=*.corp.example.com,github.com/mycompany/*

Or

go env -w GOPRIVATE=github.com/mycompany/*

• For more information about go 13 modules and new enhancements, please check out Go 1.13 Modules Release notes.

One last thing not to forget to mention, you can still configure go get to authenticate and fetch over https, all you need to do is to add the following line to $HOME/.netrc

machine github.com login USERNAME password APIKEY

• For GitHub accounts, the password can be a personal access tokens.

I posted this question and never saw the feedback (which came in several months after, it seems :).

As Kinlan mentioned, ALLOW-FROM is not supported in all browsers as an X-Frame-Options value.

The solution was to branch based on browser type. For IE, ship X-Frame-Options. For everyone else, ship X-Content-Security-Policy.

Hope this helps, and sorry for taking so long to close the loop!

This article explains in detail how to find the reason for last startup/shutdown. In my case, this was due to windows SCCM pushing updates even though I had it disabled locally. Visit the article for full details with pictures. For reference, here are the steps copy/pasted from the website:

1. Press the Windows + R keys to open the Run dialog, type eventvwr.msc, and press Enter.

2. If prompted by UAC, then click/tap on Yes (Windows 7/8) or Continue (Vista).

3. In the left pane of Event Viewer, double click/tap on Windows Logs to expand it, click on System to select it, then right click on System, and click/tap on Filter Current Log.

4. Do either step 5 or 6 below for what shutdown events you would like to see.

5. To See the Dates and Times of All User Shut Downs of the Computer

   A) In Event sources, click/tap on the drop down arrow and check the USER32 box.

   B) In the All Event IDs field, type 1074, then click/tap on OK.

   C) This will give you a list of power off (shutdown) and restart Shutdown Type of events at the top of the middle pane in Event Viewer.

   D) You can scroll through these listed events to find the events with power off as the Shutdown Type. You will notice the date and time, and what user was responsible for shutting down the computer per power off event listed.

   E) Go to step 7.

6. To See the Dates and Times of All Unexpected Shut Downs of the Computer

   A) In the All Event IDs field, type 6008, then click/tap on OK.

   B) This will give you a list of unexpected shutdown events at the top of the middle pane in Event Viewer. You can scroll through these listed events to see the date and time of each one.

If the string is at the beginning of the name, you can do this

$ compgen -f .bash
.bashrc
.bash_profile
.bash_prompt

You can use absolute imports:

/root
    /app
      /config
        config.py
      /source
        file.ipynb

# In the file.ipynb importing the config.py file
from root.app.config import config

you have to git add css/mobile.css the new file and git rm css/iphone.css, so git knows about it. then it will show the same output in git status

you can see it clearly in the status output (the new name of the file):

# Untracked files:
#   (use "git add <file>..." to include in what will be committed)

and (the old name):

# Changed but not updated:
#   (use "git add/rm <file>..." to update what will be committed)

i think behind the scenes git mv is nothing more than a wrapper script which does exactly that: delete the file from the index and add it under a different name

As the cause of the error is obvious, here's some information that should help you solve the problem:

See this MS article about Naming Files, Paths, and Namespaces

Here's a quote from the link:

Maximum Path Length Limitation In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is "D:\some 256-character path string<NUL>" where "<NUL>" represents the invisible terminating null character for the current system codepage. (The characters < > are used here for visual clarity and cannot be part of a valid path string.)

And a few workarounds (taken from the comments):

There are ways to solve the various problems. The basic idea of the solutions listed below is always the same: Reduce the path-length in order to have path-length + name-length < MAX_PATH. You may:

• Share a subfolder
• Use the commandline to assign a drive letter by means of SUBST
• Use AddConnection under VB to assign a drive letter to a path

Delegate.BeginInvoke() asynchronously queues the call of a delegate and returns control immediately. When using Delegate.BeginInvoke(), you should call Delegate.EndInvoke() in the callback method to get the results.

Delegate.Invoke() synchronously calls the delegate in the same thread.

Kotlin code:

Start the SecondActivity:

startActivity(Intent(context, SecondActivity::class.java)
    .putExtra(SecondActivity.PARAM_GAME_ID, gameId))

Get the Id in SecondActivity:

class CaptureActivity : AppCompatActivity() {

    companion object {
        const val PARAM_GAME_ID = "PARAM_GAME_ID"
    }

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        val gameId = intent.getStringExtra(PARAM_GAME_ID)
        // TODO use gameId
    }
}

where gameId is String? (can be null)

'\u0000' is the default value for a character. Its decimal equivalent is 0.

When you are declaring some char variable without initializing it, '\u0000' will be assigned to it by default.

see this code

public class Test {
    char c;

    public static void main(String args[]) throws Exception {
        Test t = new Test();
        char c1 = '\u0000';
        System.out.println(t.c);
        System.out.println(c1);
        System.out.println(t.c == c1);
    }
}

This code will print true for the last print.

If you were originally looking for the answer to this question (int value in sorted (Ascending) int array), then you can use the following code that performs a binary search (fastest result):

static inline bool exists(int ints[], int size, int k) // array, array's size, searched value
{
    if (size <= 0)      // check that array size is not null or negative
         return false;
    // sort(ints, ints + size); // uncomment this line if array wasn't previously sorted
    return (std::binary_search(ints, ints + size, k));
}

edit: Also works for unsorted int array if uncommenting sort.

You could simply use ^[\w.]+ to match A-Z, a-z, 0-9 and _

This problem due to that you try to compile project that has the files of OLder SVN than you currently use.

You have two solutions to resolve this problem

1. to install the version 1.6 SVN to be compatible with project SVN files
2. try to upgrade the project ..( not always working ).

Follow that tutorial: Disable JavaScript With Chrome DevTools

I find git stash very useful for temporal handling of all 'dirty' states.

Most certainly, export JAVA_HOME=/usr/bin/java is the culprit. This env var should point to the JDK or JRE installation directory. Googling shows that the best option for MacOS X seems to be export JAVA_HOME=/Library/Java/Home.

Slightly different version I wrote using reflection for my needs. I had to export a list of objects to csv. In case someone wants to use it for future.

public class CsvExport<T> where T: class
    {
        public List<T> Objects;

        public CsvExport(List<T> objects)
        {
            Objects = objects;
        }

        public string Export()
        {
            return Export(true);
        }

        public string Export(bool includeHeaderLine)
        {

            StringBuilder sb = new StringBuilder();
            //Get properties using reflection.
            IList<PropertyInfo> propertyInfos = typeof(T).GetProperties();

            if (includeHeaderLine)
            {
                //add header line.
                foreach (PropertyInfo propertyInfo in propertyInfos)
                {
                    sb.Append(propertyInfo.Name).Append(",");
                }
                sb.Remove(sb.Length - 1, 1).AppendLine();
            }

            //add value for each property.
            foreach (T obj in Objects)
            {               
                foreach (PropertyInfo propertyInfo in propertyInfos)
                {
                    sb.Append(MakeValueCsvFriendly(propertyInfo.GetValue(obj, null))).Append(",");
                }
                sb.Remove(sb.Length - 1, 1).AppendLine();
            }

            return sb.ToString();
        }

        //export to a file.
        public void ExportToFile(string path)
        {
            File.WriteAllText(path, Export());
        }

        //export as binary data.
        public byte[] ExportToBytes()
        {
            return Encoding.UTF8.GetBytes(Export());
        }

        //get the csv value for field.
        private string MakeValueCsvFriendly(object value)
        {
            if (value == null) return "";
            if (value is Nullable && ((INullable)value).IsNull) return "";

            if (value is DateTime)
            {
                if (((DateTime)value).TimeOfDay.TotalSeconds == 0)
                    return ((DateTime)value).ToString("yyyy-MM-dd");
                return ((DateTime)value).ToString("yyyy-MM-dd HH:mm:ss");
            }
            string output = value.ToString();

            if (output.Contains(",") || output.Contains("\""))
                output = '"' + output.Replace("\"", "\"\"") + '"';

            return output;

        }
    }

Usage sample : (updated per comment)

CsvExport<BusinessObject> csv= new CsvExport<BusinessObject>(GetBusinessObjectList());
Response.Write(csv.Export());

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

Permanently authenticating with Git repositories,

Run the following command to enable credential caching.

$ git config credential.helper store
$ git push https://github.com/repo.git

Username for 'https://github.com': <USERNAME>
Password for 'https://[email protected]': <PASSWORD>

Use should also specify caching expire,

git config --global credential.helper 'cache --timeout 7200'

After enabling credential caching, it will be cached for 7200 seconds (2 hours).

Note: Credential helper stores an unencrypted password on a local disk.

if you want the object on the stack, try this:

MyClass myclass;
myclass.DoSomething();

If you need a pointer to that object:

MyClass* myclassptr = &myclass;
myclassptr->DoSomething();

Alternatively, you can install "SourceForge Notepad++ Compare Plugin 1.5.6". It provides compare functionality between two files and show the differences between two files.

Unless this is a one-off data conversion, chances are you will benefit from using a calendar table.

Having such a table makes it really easy to filter or aggregate data for non-standard periods in addition to regular ISO weeks. Weeks usually behave a bit differently across companies and the departments within them. As soon as you leave "ISO-land" the built-in date functions can't help you.

create table calender(
   day           date      not null -- Truncated date
  ,iso_year_week number(6) not null -- ISO Year week  (IYYYIW)
  ,retail_week   number(6) not null -- Monday to Sunday (YYYYWW)
  ,purchase_week number(6) not null -- Sunday to Saturday (YYYYWW)
  ,primary key(day)
);

You can either create additional tables for "purchase_weeks" or "retail_weeks", or simply aggregate on the fly:

select a.colA
      ,a.colB
      ,b.first_day
      ,b.last_day
  from your_table_with_weeks a
  join (select iso_year_week
              ,min(day) as first_day
              ,max(day) as last_day
          from calendar
         group  
            by iso_year_week
       ) b on(a.iso_year_week = b.iso_year_week)

If you process a large number of records, aggregating on the fly won't make a noticable difference, but if you are performing single-row you would benefit from creating tables for the weeks as well.

Using calendar tables provides a subtle performance benefit in that the optimizer can provide better estimates on static columns than on nested add_months(to_date(to_char())) function calls.

For me the solution was to set the version of the maven compiler plugin to 3.8.0 and specify the release (9 for in your case, 11 in mine)

    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.8.0</version>
      <configuration>
        <release>11</release>
      </configuration>
    </plugin>

When you use onChange={this.onFieldChange('name').bind(this)} in your input you must declare your state empty string as a value of property field.

incorrect way:

this.state ={
       fields: {},
       errors: {},
       disabled : false
    }

correct way:

this.state ={
       fields: {
         name:'',
         email: '',
         message: ''
       },
       errors: {},
       disabled : false
    }

JSON.stringify takes more optional arguments.

Try:

 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, 4); // Indented 4 spaces
 JSON.stringify({a:1,b:2,c:{d:1,e:[1,2]}}, null, "\t"); // Indented with tab

How can I beautify JSON programmatically?

Should work in modern browsers, and it is included in json2.js if you need a fallback for browsers that don't support the JSON helper functions. For display purposes, put the output in a <pre> tag to get newlines to show.

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

There are also some slightly different, but less developed questions/answers here on Stack Overflow:

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

Clear your old viewmodel and set the new data to the adapter and call notifyDataSetChanged()

This section of the boto3 documentation is helpful.

Here's what worked for me:

session = boto3.Session(profile_name='dev')
client = session.client('cloudfront')

This will help you

echo '<pre>';

$output = print_r($array,1);

echo '</pre>';

using echo '<pre>'; is useless, but var_export($var); will do the thing which you are expecting.

A simple way to make it work is to run your script from the parent directory using python's -m flag, e.g. python -m packagename.scriptname. Obviously in this situation you need an __init__.py file to turn your directory into a package.

There's a new package called installr that can update your R version within R on the Windows platform. The package was built under version 3.2.3

From R Studio, click on Tools and select Install Packages... then type the name "installr" and click install. Alternatively, you may type install.packages("installr") in the Console.

Once R studio is done installing the package, load it by typing require(installr) in the Console.

To start the updating process for your R installation, type updateR(). This function will check for newer versions of R and if available, it will guide you through the decisions you need to make. If your R installation is up-to-date, it will return FALSE.

If you choose to download and install a newer version. There's an option for copying/moving all of your packages from the current R installation to the newer R installation which is very handy.

Quit and restart R Studio once the update process is over. R Studio will load the newer R version.

Follow this link if you wish to learn more on how to use the installr package.

I just experienced this with the line:

$('<div id="editor" />').dialogelfinder({

I got the error "dialogelfinder is not a function" because another component was inserting a call to load an older version of JQuery (1.7.2) after the newer version was loaded.

As soon as I commented out the second load, the error went away.

While looking at the same problem, I found an example

<style type="text/css">
#topright {
    position: absolute;
    right: 0;
    top: 0;
    display: block;
    height: 125px;
    width: 125px;
    background: url(TRbanner.gif) no-repeat;
    text-indent: -999em;
    text-decoration: none;
}
</style>

<a id="topright" href="#" title="TopRight">Top Right Link Text</a>

The trick here is to create a small, (I used GIMP) a PNG (or GIF) that has a transparent background, (and then just delete the opposite bottom corner.)

Please try this:

with open('filename','r',buffering=100000) as f:
    for line in f:
        print line

DEMO : http://jsfiddle.net/shfj70qp/

//dd/mm/yyyy 

var date = new Date();
var month = date.getMonth();
var day = date.getDate();
var year = date.getFullYear();

console.log(month+"/"+day+"/"+year);

If you are going to use any DDOS provider like Akamai, they have a maximum limitation of 8k in the response header size. So essentially try to limit your response header size below 8k.

Autobahn has a good websocket client implementation for Python as well as some good examples. I tested the following with a Tornado WebSocket server and it worked.

from twisted.internet import reactor
from autobahn.websocket import WebSocketClientFactory, WebSocketClientProtocol, connectWS


class EchoClientProtocol(WebSocketClientProtocol):

   def sendHello(self):
      self.sendMessage("Hello, world!")

   def onOpen(self):
      self.sendHello()

   def onMessage(self, msg, binary):
      print "Got echo: " + msg
      reactor.callLater(1, self.sendHello)


if __name__ == '__main__':

   factory = WebSocketClientFactory("ws://localhost:9000")
   factory.protocol = EchoClientProtocol
   connectWS(factory)
   reactor.run()

I'd like to suggest a related solution, which is to pass the @Value-annotated fields as parameters to the constructor, instead of using the ReflectionTestUtils class.

Instead of this:

public class Foo {

    @Value("${foo}")
    private String foo;
}

and

public class FooTest {

    @InjectMocks
    private Foo foo;

    @Before
    public void setUp() {
        ReflectionTestUtils.setField(Foo.class, "foo", "foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Do this:

public class Foo {

    private String foo;

    public Foo(@Value("${foo}") String foo) {
        this.foo = foo;
    }
}

and

public class FooTest {

    private Foo foo;

    @Before
    public void setUp() {
        foo = new Foo("foo");
    }

    @Test
    public void testFoo() {
        // stuff
    }
}

Benefits of this approach: 1) we can instantiate the Foo class without a dependency container (it's just a constructor), and 2) we're not coupling our test to our implementation details (reflection ties us to the field name using a string, which could cause a problem if we change the field name).

Here's your problem:

if(imgArray[i] == img)

You're comparing an array element to a DOM object.

Call: call invokes the function and allows you to pass arguments one by one

Apply: Apply invokes the function and allows you to pass arguments as an array

Bind: Bind returns a new function, allowing you to pass in a this array and any number of arguments.

var person1 = {firstName: 'Raju', lastName: 'king'};_x000D_
var person2 = {firstName: 'chandu', lastName: 'shekar'};_x000D_
_x000D_
function greet(greeting) {_x000D_
    console.log(greeting + ' ' + this.firstName + ' ' + this.lastName);_x000D_
}_x000D_
function greet2(greeting) {_x000D_
        console.log( 'Hello ' + this.firstName + ' ' + this.lastName);_x000D_
    }_x000D_
_x000D_
_x000D_
greet.call(person1, 'Hello'); // Hello Raju king_x000D_
greet.call(person2, 'Hello'); // Hello chandu shekar_x000D_
_x000D_
_x000D_
_x000D_
greet.apply(person1, ['Hello']); // Hello Raju king_x000D_
greet.apply(person2, ['Hello']); // Hello chandu shekar_x000D_
_x000D_
var greetRaju = greet2.bind(person1);_x000D_
var greetChandu = greet2.bind(person2);_x000D_
_x000D_
greetRaju(); // Hello Raju king_x000D_
greetChandu(); // Hello chandu shekar

If this is just plain vanilla C, then:

strcpy(buffer, text.c_str());

Assuming that buffer is allocated and large enough to hold the contents of 'text', which is the assumption in your original code.

If encrypt() takes a 'const char *' then you can use

encrypt(text.c_str())

and you do not need to copy the string.

in Bootstrap, web inspector says the Headings are set to 'inherit'

all i needed to set my page to the new font was

div, p {font-family: Algerian}

that's in .scss

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

Here is an efficient way to solve this question using For loops in Java

 public static void main(String[] args) {

    int [] numbers = { 1, 2, 3, 4 };
    int size = numbers.length;

    int sum = 0;
    for (int i = 0; i < size; i++) {
        sum += numbers[i];
    }

    System.out.println(sum);
}

You can print some text by using SELECT command like that:

SELECT 'some text'

Result:

+-----------+
| some text |
+-----------+
| some text |
+-----------+
1 row in set (0.02 sec)

The problem with MAC address is that there can be many network adapters connected to the computer. Most of the newest ones have two by default (wi-fi + cable). In such situation one would have to know which adapter's MAC address should be used. I tested MAC solution on my system, but I have 4 adapters (cable, WiFi, TAP adapter for Virtual Box and one for Bluetooth) and I was not able to decide which MAC I should take... If one would decide to use adapter which is currently in use (has addresses assigned) then new problem appears since someone can take his/her laptop and switch from cable adapter to wi-fi. With such condition MAC stored when laptop was connected through cable will now be invalid.

For example those are adapters I found in my system:

lo MS TCP Loopback interface
eth0 Intel(R) Centrino(R) Advanced-N 6205
eth1 Intel(R) 82579LM Gigabit Network Connection
eth2 VirtualBox Host-Only Ethernet Adapter
eth3 Sterownik serwera dostepu do sieci LAN Bluetooth

Code I've used to list them:

Enumeration<NetworkInterface> nis = NetworkInterface.getNetworkInterfaces();
while (nis.hasMoreElements()) {
    NetworkInterface ni = nis.nextElement();
    System.out.println(ni.getName() + " " + ni.getDisplayName());
}

From the options listen on this page, the most acceptable for me, and the one I've used in my solution is the one by @Ozhan Duz, the other one, similar to @finnw answer where he used JACOB, and worth mentioning is com4j - sample which makes use of WMI is available here:

ISWbemLocator wbemLocator = ClassFactory.createSWbemLocator();
ISWbemServices wbemServices = wbemLocator.connectServer("localhost","Root\\CIMv2","","","","",0,null);
ISWbemObjectSet result = wbemServices.execQuery("Select * from Win32_SystemEnclosure","WQL",16,null);
for(Com4jObject obj : result) {
    ISWbemObject wo = obj.queryInterface(ISWbemObject.class);
    System.out.println(wo.getObjectText_(0));
}

This will print some computer information together with computer Serial Number. Please note that all classes required by this example has to be generated by maven-com4j-plugin. Example configuration for maven-com4j-plugin:

<plugin>
    <groupId>org.jvnet.com4j</groupId>
    <artifactId>maven-com4j-plugin</artifactId>
    <version>1.0</version>
    <configuration>
        <libId>565783C6-CB41-11D1-8B02-00600806D9B6</libId>
        <package>win.wmi</package>
        <outputDirectory>${project.build.directory}/generated-sources/com4j</outputDirectory>
    </configuration>
    <executions>
        <execution>
            <id>generate-wmi-bridge</id>
            <goals>
                <goal>gen</goal>
            </goals>
        </execution>
    </executions>
</plugin>

Above's configuration will tell plugin to generate classes in target/generated-sources/com4j directory in the project folder.

For those who would like to see ready-to-use solution, I'm including links to the three classes I wrote to get machine SN on Windows, Linux and Mac OS:

• Java code to get computer SN on Windows
• Java code to get computer SN on Linux
• Java code to get computer SN on Mac OS

I needed a more general solution to account for the possibility of multiple dictionaries in the list having the key value, and a straightforward implementation using list comprehension:

dict_indices = [i for i, d in enumerate(dict_list) if d[dict_key] == key_value] 

You can use the OpenSSL Command line tool. The following commands should do the trick

openssl pkcs12 -in client_ssl.pfx -out client_ssl.pem -clcerts

openssl pkcs12 -in client_ssl.pfx -out root.pem -cacerts

If you want your file to be password protected etc, then there are additional options.

You can read the entire documentation here.

i have same this because in httpd.conf in apache PHPIniDir D:/wamp/bin/php/php5.5.12 that was incorrect

You might need to collect the stats as you go, but @@ROWCOUNT captures this:

declare @Fish table (
Name varchar(32)
)

insert into @Fish values ('Cod')
insert into @Fish values ('Salmon')
insert into @Fish values ('Butterfish')
update @Fish set Name = 'LurpackFish' where Name = 'Butterfish'
select @@ROWCOUNT  --gives 1

update @Fish set Name = 'Dinner'
select @@ROWCOUNT -- gives 3

I came researching the options that I would have to do this, however, I believe the method I use is the simplest:

SELECT COUNT(*), 
       DATEADD(dd, DATEDIFF(dd, 0, date_field),0) as dtgroup 
FROM TABLE 
GROUP BY DATEADD(dd, DATEDIFF(dd, 0, date_field),0) 
ORDER BY dtgroup ASC;

@AamirAdnan's answer missing field.label; the other way to show the errors in few lines.

{% if form.errors %}
    <!-- Error messaging -->
    <div id="errors">
        <div class="inner">
            <p>There were some errors in the information you entered. Please correct the following:</p>
            <ul>
                {% for field in form %}
                    {% if field.errors %}<li>{{ field.label }}: {{ field.errors|striptags }}</li>{% endif %}
                {% endfor %}
            </ul>
        </div>
    </div>
    <!-- /Error messaging -->
{% endif %}

$header3 = @("Field_1","Field_2","Field_3","Field_4","Field_5")     

Import-Csv $fileName -Header $header3 -Delimiter "`t" | select -skip 3 | Foreach-Object {

    $record = $indexName 
    foreach ($property in $_.PSObject.Properties){

        #doSomething $property.Name, $property.Value

            if($property.Name -like '*TextWrittenAsNumber*'){

                $record = $record + "," + '"' + $property.Value + '"' 
            }
            else{
                $record = $record + "," + $property.Value 
            }                           
    }               

        $array.add($record) | out-null  
        #write-host $record                         
}

You could write a simple generic extension method like this

public static T ConvertTo<T>(this object value)            
    where T : struct,IConvertible
{
    var sourceType = value.GetType();
    if (!sourceType.IsEnum)
        throw new ArgumentException("Source type is not enum");
    if (!typeof(T).IsEnum)
        throw new ArgumentException("Destination type is not enum");
    return (T)Enum.Parse(typeof(T), value.ToString());
}

You can make use of variable NF which is set to the total number of fields in the input record:

awk '{print $(NF-1),"\t",$NF}' file

this assumes that you have at least 2 fields.

I do not believe there is a callback-function like the one you describe.

What is normal here is to do the alterations using some server-side language, like PHP.

In PHP you could for instance fetch a hidden field from your form and do some changes if it is present.

PHP:

  $someHiddenVar = $_POST["hidden_field"];
    if (!empty($someHiddenVar)) {
        // do something 
    }

One way to go about it in Jquery is to use Ajax. You could listen to submit, return false to cancel its default behaviour and use jQuery.post() instead. jQuery.post has a success-callback.

$.post("test.php", $("#testform").serialize(), function(data) {
  $('.result').html(data);
});

You can resize image by below code:

From PIL import Image
img=Image.open('Filename.jpg') # paste image in python folder
print(img.size())
new_img=img.resize((400,400))
new_img.save('new_filename.jpg')

Here is my code, it might be sloppy but it seems to work for me anyway.

# a is the number you want the inverse for
# b is the modulus

def mod_inverse(a, b):
    r = -1
    B = b
    A = a
    eq_set = []
    full_set = []
    mod_set = []

    #euclid's algorithm
    while r!=1 and r!=0:
        r = b%a
        q = b//a
        eq_set = [r, b, a, q*-1]
        b = a
        a = r
        full_set.append(eq_set)

    for i in range(0, 4):
        mod_set.append(full_set[-1][i])

    mod_set.insert(2, 1)
    counter = 0

    #extended euclid's algorithm
    for i in range(1, len(full_set)):
        if counter%2 == 0:
            mod_set[2] = full_set[-1*(i+1)][3]*mod_set[4]+mod_set[2]
            mod_set[3] = full_set[-1*(i+1)][1]

        elif counter%2 != 0:
            mod_set[4] = full_set[-1*(i+1)][3]*mod_set[2]+mod_set[4]
            mod_set[1] = full_set[-1*(i+1)][1]

        counter += 1

    if mod_set[3] == B:
        return mod_set[2]%B
    return mod_set[4]%B

Here it is nice and simple.

root = tkinter.Tk()
root.title('My Title')

root is the window you create and root.title() sets the title of that window.

>> "1,2,3,4".split(",")
=> ["1", "2", "3", "4"]

Or for integers:

>> "1,2,3,4".split(",").map { |s| s.to_i }
=> [1, 2, 3, 4]

Or for later versions of ruby (>= 1.9 - as pointed out by Alex):

>> "1,2,3,4".split(",").map(&:to_i)
=> [1, 2, 3, 4]

     foreach (DataRow row in dt.Rows) 
     {
        foreach (DataColumn col in dt.Columns)
           Console.WriteLine(row[col]);
     }

We can use an optional merger function also in case of same key collision. For example, If two or more persons have the same getLast() value, we can specify how to merge the values. If we not do this, we could get IllegalStateException. Here is the example to achieve this...

Map<String, Person> map = 
roster
    .stream()
    .collect(
        Collectors.toMap(p -> p.getLast(),
                         p -> p,
                         (person1, person2) -> person1+";"+person2)
    );

If you want an index, you can use std::find in combination with std::distance.

auto it = std::find(Names.begin(), Names.end(), old_name_);
if (it == Names.end())
{
  // name not in vector
} else
{
  auto index = std::distance(Names.begin(), it);
}

Check for cookies using a pure server side solution i have introduced here then check for javascript by dropping a cookie using Jquery.Cookie and then check for cookie this way u check for both cookies and javascript

The top answer is a very bad practice, one should never ever link to an empty hash as it can create problems down the road.

Best is to bind an event handler to the element as numerous other people have stated, however, <a href="javascript:doStuff();">do stuff</a> works perfectly in every modern browser, and I use it extensively when rendering templates to avoid having to rebind for each instance. In some cases, this approach offers better performance. YMMV

Another interesting tid-bit....

onclick & href have different behaviors when calling javascript directly.

onclick will pass this context correctly, whereas href won't, or in other words <a href="javascript:doStuff(this)">no context</a> won't work, whereas <a onclick="javascript:doStuff(this)">no context</a> will.

Yes, I omitted the href. While that doesn't follow the spec, it will work in all browsers, although, ideally it should include a href="javascript:void(0);" for good measure

You can also use $("ul li:first-child") to only get the direct children of the UL.

I agree though, you need an ID or something else to identify the main UL otherwise it will just select them all. If you had a div with an ID around the UL the easiest thing to do would be$("#someDiv > ul > li")

I created a new device. Deleted the previous one.

You must create your own class type and override the ToString() method to return the text you want. Here is a simple example of a class you can use:

public class ComboboxItem
{
    public string Text { get; set; }
    public object Value { get; set; }

    public override string ToString()
    {
        return Text;
    }
}

The following is a simple example of its usage:

private void Test()
{
    ComboboxItem item = new ComboboxItem();
    item.Text = "Item text1";
    item.Value = 12;

    comboBox1.Items.Add(item);

    comboBox1.SelectedIndex = 0;

    MessageBox.Show((comboBox1.SelectedItem as ComboboxItem).Value.ToString());
}

Page Control can be contained in Window Control but vice versa is not possible

You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).

WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.

@user1417684 and @chris-foster are right!

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

You could try to create an empty form, method=get, and submitting it.

<form id='reloader' method='get' action="enter url here"> </form>
<script>
// to reload the page, try
document.getElementById('reloader').submit();
</script>

You need to:

unbind('scroll')

At the moment you are not specifying the event to unbind.

Should just be this:

var jobject = JsonConvert.DeserializeObject<RootObject>(jsonstring);

You can paste the json string to here: http://json2csharp.com/ to check your classes are correct.

You can Use both disabled or readonly attribute of input . Using disable attribute will omit that value at form submit, so if you want that values at submit event make them readonly instead of disable.

<input type="text" readonly> 

or

 <input type="text" disabled>

As GTalk is gone from the SDK, it might be a good idea to make a 'standard' push messaging system. That way, only one service has to run, only one extra tcp connection needs to be open. Applications should talk to this service using Intents and should first request permission to send and receive notification from the service. The service should then notify the user a new application wants to send and receive messages. The user will then grant or deny permission, so he stays in control. The application will then register an action + category to the service, so the service knows how to deliver the pushed message.

Would the a good idea or not?

Newer versions of Python come with py, the Python Launcher, which is always in the PATH.

Here is how to invoke pip via py:

py -m pip install <packagename>

py allows having several versions of Python on the same machine.

As an example, here is how to invoke the pip from Python 2.7:

py -2.7 -m pip install <packagename>

final has three good reasons:

• instance variables set by constructor only become immutable
• methods not to be overridden become final, use this with real reasons, not by default
• local variables or parameters to be used in anonimous classes inside a method need to be final

Like methods, local variables and parameters need not to be declared final. As others said before, this clutters the code becoming less readable with very little efford for compiler performace optimisation, this is no real reason for most code fragments.

Note: This answer is really old and things may have changed in WordPress land since.

I am guessing that you need to detect the WordPress root from your plugin or theme. I use the following code in FireStats to detect the root WordPress directory where FireStats is installed a a WordPress plugin.

function fs_get_wp_config_path()
{
    $base = dirname(__FILE__);
    $path = false;

    if (@file_exists(dirname(dirname($base))."/wp-config.php"))
    {
        $path = dirname(dirname($base))."/wp-config.php";
    }
    else
    if (@file_exists(dirname(dirname(dirname($base)))."/wp-config.php"))
    {
        $path = dirname(dirname(dirname($base)))."/wp-config.php";
    }
    else
        $path = false;

    if ($path != false)
    {
        $path = str_replace("\\", "/", $path);
    }
    return $path;
}

Yes, that is fine. $_POST is just another variable, except it has (super)global scope.

$_POST = array();

...will be quite enough. The loop is useless. It's probably best to keep it as an array rather than unset it, in case other files are attempting to read it and assuming it is an array.

As other answers already suggested, you must have MinGW installed. The additional part is to add the following two folders to the PATH environment variable.

• C:\MinGW\bin
• C:\MinGW\msys\1.0\bin

Obviously, adjust the path based on where you installed MinGW. Also, dont forget to open a new command line terminal.

There are not many good reasons this would fail, especially the regsvr32 step. Run dumpbin /exports on that dll. If you don't see DllRegisterServer then you've got a corrupt install. It should have more side-effects, you wouldn't be able to build C/C++ projects anymore.

One standard failure mode is running this on a 64-bit operating system. This is 32-bit unmanaged code, you would indeed get the 'class not registered' exception. Project + Properties, Build tab, change Platform Target to x86.

Cookies are your best bet. Look for the jquery cookie plugin.

Cookies are designed for this sort of situation -- you want to keep some information about this client on client side. Just be aware that cookies are passed back and forth on every web request so you can't store large amounts of data in there. But just a simple answer to a question should be fine.

All hidden-*-up, hidden-* classes doesn't work for me, so I'm adding self-made hidden class before visible-*(which works for current bootstrap version). It is very useful if you need to show div only for one screen, and hide for all others.

CSS:

.hidden {display:none;}

HTML:

<div class="col-xs-12 hidden visible-xs visible-sm">
   <img src="photo.png" style="width:100%">
</div>

Actually, in VS Code 1.48.1, there is a toggleTerminal command; I don't know if it was available in previous versions ;) You can utilize it in the keybindings.json file.

This worked for me on Windows, and should also works on Linux.

{
    "key": "ctrl+alt+right",
    "command": "workbench.action.terminal.toggleTerminal",
    "when": "editorTextFocus || terminalFocus"
}

The answers mentioning canvas.width return the internal dimensions of the canvas, i.e. those specified when creating the element:

<canvas width="500" height="200">

If you size the canvas with CSS, its DOM dimensions are accessible via .scrollWidth and .scrollHeight:

var canvasElem = document.querySelector('canvas');_x000D_
document.querySelector('#dom-dims').innerHTML = 'Canvas DOM element width x height: ' +_x000D_
      canvasElem.scrollWidth +_x000D_
      ' x ' +_x000D_
      canvasElem.scrollHeight_x000D_
_x000D_
var canvasContext = canvasElem.getContext('2d');_x000D_
document.querySelector('#internal-dims').innerHTML = 'Canvas internal width x height: ' +_x000D_
      canvasContext.canvas.width +_x000D_
      ' x ' +_x000D_
      canvasContext.canvas.height;_x000D_
_x000D_
canvasContext.fillStyle = "#00A";_x000D_
canvasContext.fillText("Distorted", 0, 10);

I needed a row of clickable elephants, vertically centered, but without using a table to get around some Internet Explorer 9 weirdness.

Obviously you don't need the borders, but they can help you see how it works.

For symfony 2.6 and above we can use

{{ app.user.getFirstname() }}

as app.security global variable for Twig template has been deprecated and will be removed from 3.0

more info:

http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements

and see the global variables in

http://symfony.com/doc/current/reference/twig_reference.html

If you're using SQL Server 2005 or later, use varchar(MAX). The text datatype is deprecated and should not be used for new development work. From the docs:

Important

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Exception handling is included in free standing implementations.

The reason of this is that you possibly use gcc to compile your code. If you compile with the option -### you will notice it is missing the linker-option -lstdc++ when it invokes the linker process . Compiling with g++ will include that library, and thus the symbols defined in it.

You need to create a set of escaped (with \) parentheses (that match the parentheses) and a group of regular parentheses that create your capturing group:

var regExp = /\(([^)]+)\)/;_x000D_
var matches = regExp.exec("I expect five hundred dollars ($500).");_x000D_
_x000D_
//matches[1] contains the value between the parentheses_x000D_
console.log(matches[1]);

Breakdown:

• \( : match an opening parentheses
• ( : begin capturing group
• [^)]+: match one or more non ) characters
• ) : end capturing group
• \) : match closing parentheses

Here is a visual explanation on RegExplained

In a single-byte ASCII-compatible encoding (e.g. Latin-1), ASCII characters are simply bytes in the range 0 to 127. So you can use something like [\x80-\xFF] to detect non-ASCII characters.

The easiest and straightforward approach (IMHO) - no config files not too much hassle

Just create another ssh key.

Let's say you have aa new work GitHub account, just create a new key for it:

sh-keygen -t rsa -C "email@work_mail.com" -f "id_rsa_work_user1"`

Now you should have the old one and the new one, to see them, run:

ls -al ~/.ssh

You need to run the above only once.

From now on, every time you want to switch between the two, just run:

ssh-add -D
ssh-add ~/.ssh/id_rsa_work_user1 #make to use this without the suffix .pub

In order the switch to the old one, run again:

 ssh-add -D
 ssh-add ~/.ssh/<previous id_rsa>

teastburn has the right approach. Even simpler is to call the method directly and return the answer:

class PHPUnitUtil
{
  public static function callMethod($obj, $name, array $args) {
        $class = new \ReflectionClass($obj);
        $method = $class->getMethod($name);
        $method->setAccessible(true);
        return $method->invokeArgs($obj, $args);
    }
}

You can call this simply in your tests by:

$returnVal = PHPUnitUtil::callMethod(
                $this->object,
                '_nameOfProtectedMethod', 
                array($arg1, $arg2)
             );

The best way to center content in a table (for example <video> or <img>) is to do the following:

<table width="100%" border="0" cellspacing="0" cellpadding="100%">
<tr>
<td>Video Tag 1 Here</td>
<td>Video Tag 2 Here</td>
</tr>
</table>

Overloading new and delete

^{Note: This only deals with the syntax of overloading new and delete, not with the implementation of such overloaded operators. I think that the semantics of overloading new and delete deserve their own FAQ, within the topic of operator overloading I can never do it justice.}

Basics

In C++, when you write a new expression like new T(arg) two things happen when this expression is evaluated: First operator new is invoked to obtain raw memory, and then the appropriate constructor of T is invoked to turn this raw memory into a valid object. Likewise, when you delete an object, first its destructor is called, and then the memory is returned to operator delete.
C++ allows you to tune both of these operations: memory management and the construction/destruction of the object at the allocated memory. The latter is done by writing constructors and destructors for a class. Fine-tuning memory management is done by writing your own operator new and operator delete.

The first of the basic rules of operator overloading – don’t do it – applies especially to overloading new and delete. Almost the only reasons to overload these operators are performance problems and memory constraints, and in many cases, other actions, like changes to the algorithms used, will provide a much higher cost/gain ratio than attempting to tweak memory management.

The C++ standard library comes with a set of predefined new and delete operators. The most important ones are these:

void* operator new(std::size_t) throw(std::bad_alloc); 
void  operator delete(void*) throw(); 
void* operator new[](std::size_t) throw(std::bad_alloc); 
void  operator delete[](void*) throw(); 

The first two allocate/deallocate memory for an object, the latter two for an array of objects. If you provide your own versions of these, they will not overload, but replace the ones from the standard library.
If you overload operator new, you should always also overload the matching operator delete, even if you never intend to call it. The reason is that, if a constructor throws during the evaluation of a new expression, the run-time system will return the memory to the operator delete matching the operator new that was called to allocate the memory to create the object in. If you do not provide a matching operator delete, the default one is called, which is almost always wrong.
If you overload new and delete, you should consider overloading the array variants, too.

Placement new

C++ allows new and delete operators to take additional arguments.
So-called placement new allows you to create an object at a certain address which is passed to:

class X { /* ... */ };
char buffer[ sizeof(X) ];
void f()
{ 
  X* p = new(buffer) X(/*...*/);
  // ... 
  p->~X(); // call destructor 
} 

The standard library comes with the appropriate overloads of the new and delete operators for this:

void* operator new(std::size_t,void* p) throw(std::bad_alloc); 
void  operator delete(void* p,void*) throw(); 
void* operator new[](std::size_t,void* p) throw(std::bad_alloc); 
void  operator delete[](void* p,void*) throw(); 

Note that, in the example code for placement new given above, operator delete is never called, unless the constructor of X throws an exception.

You can also overload new and delete with other arguments. As with the additional argument for placement new, these arguments are also listed within parentheses after the keyword new. Merely for historical reasons, such variants are often also called placement new, even if their arguments are not for placing an object at a specific address.

Class-specific new and delete

Most commonly you will want to fine-tune memory management because measurement has shown that instances of a specific class, or of a group of related classes, are created and destroyed often and that the default memory management of the run-time system, tuned for general performance, deals inefficiently in this specific case. To improve this, you can overload new and delete for a specific class:

class my_class { 
  public: 
    // ... 
    void* operator new();
    void  operator delete(void*,std::size_t);
    void* operator new[](size_t);
    void  operator delete[](void*,std::size_t);
    // ... 
}; 

Overloaded thus, new and delete behave like static member functions. For objects of my_class, the std::size_t argument will always be sizeof(my_class). However, these operators are also called for dynamically allocated objects of derived classes, in which case it might be greater than that.

Global new and delete

To overload the global new and delete, simply replace the pre-defined operators of the standard library with our own. However, this rarely ever needs to be done.

Try like this

 $("#drop").change(function () {
        var end = this.value;
        var firstDropVal = $('#pick').val();
    });

You can use Eclipse DDMS perspective to see connected devices and browse through files, you can also pull and push files to the device. You can also do a bunch of stuff using DDMS, this link explains a little bit more of DDMS uses.

EDIT:

If you just want to copy a database you can locate the database on eclipse DDMS file explorer, select it and then pull the database from the device to your computer.

If you want to rotate a vector you should construct what is known as a rotation matrix.

Rotation in 2D

Say you want to rotate a vector or a point by ?, then trigonometry states that the new coordinates are

    x' = x cos ? - y sin ?
    y' = x sin ? + y cos ?

To demo this, let's take the cardinal axes X and Y; when we rotate the X-axis 90° counter-clockwise, we should end up with the X-axis transformed into Y-axis. Consider

    Unit vector along X axis = <1, 0>
    x' = 1 cos 90 - 0 sin 90 = 0
    y' = 1 sin 90 + 0 cos 90 = 1
    New coordinates of the vector, <x', y'> = <0, 1>  ?  Y-axis

When you understand this, creating a matrix to do this becomes simple. A matrix is just a mathematical tool to perform this in a comfortable, generalized manner so that various transformations like rotation, scale and translation (moving) can be combined and performed in a single step, using one common method. From linear algebra, to rotate a point or vector in 2D, the matrix to be built is

    |cos ?   -sin ?| |x| = |x cos ? - y sin ?| = |x'|
    |sin ?    cos ?| |y|   |x sin ? + y cos ?|   |y'|

Rotation in 3D

That works in 2D, while in 3D we need to take in to account the third axis. Rotating a vector around the origin (a point) in 2D simply means rotating it around the Z-axis (a line) in 3D; since we're rotating around Z-axis, its coordinate should be kept constant i.e. 0° (rotation happens on the XY plane in 3D). In 3D rotating around the Z-axis would be

    |cos ?   -sin ?   0| |x|   |x cos ? - y sin ?|   |x'|
    |sin ?    cos ?   0| |y| = |x sin ? + y cos ?| = |y'|
    |  0       0      1| |z|   |        z        |   |z'|

around the Y-axis would be

    | cos ?    0   sin ?| |x|   | x cos ? + z sin ?|   |x'|
    |   0      1       0| |y| = |         y        | = |y'|
    |-sin ?    0   cos ?| |z|   |-x sin ? + z cos ?|   |z'|

around the X-axis would be

    |1     0           0| |x|   |        x        |   |x'|
    |0   cos ?    -sin ?| |y| = |y cos ? - z sin ?| = |y'|
    |0   sin ?     cos ?| |z|   |y sin ? + z cos ?|   |z'|

Note 1: axis around which rotation is done has no sine or cosine elements in the matrix.

Note 2: This method of performing rotations follows the Euler angle rotation system, which is simple to teach and easy to grasp. This works perfectly fine for 2D and for simple 3D cases; but when rotation needs to be performed around all three axes at the same time then Euler angles may not be sufficient due to an inherent deficiency in this system which manifests itself as Gimbal lock. People resort to Quaternions in such situations, which is more advanced than this but doesn't suffer from Gimbal locks when used correctly.

I hope this clarifies basic rotation.

Rotation not Revolution

The aforementioned matrices rotate an object at a distance r = v(x² + y²) from the origin along a circle of radius r; lookup polar coordinates to know why. This rotation will be with respect to the world space origin a.k.a revolution. Usually we need to rotate an object around its own frame/pivot and not around the world's i.e. local origin. This can also be seen as a special case where r = 0. Since not all objects are at the world origin, simply rotating using these matrices will not give the desired result of rotating around the object's own frame. You'd first translate (move) the object to world origin (so that the object's origin would align with the world's, thereby making r = 0), perform the rotation with one (or more) of these matrices and then translate it back again to its previous location. The order in which the transforms are applied matters. Combining multiple transforms together is called concatenation or composition.

Composition

I urge you to read about linear and affine transformations and their composition to perform multiple transformations in one shot, before playing with transformations in code. Without understanding the basic maths behind it, debugging transformations would be a nightmare. I found this lecture video to be a very good resource. Another resource is this tutorial on transformations that aims to be intuitive and illustrates the ideas with animation (caveat: authored by me!).

Rotation around Arbitrary Vector

A product of the aforementioned matrices should be enough if you only need rotations around cardinal axes (X, Y or Z) like in the question posted. However, in many situations you might want to rotate around an arbitrary axis/vector. The Rodrigues' formula (a.k.a. axis-angle formula) is a commonly prescribed solution to this problem. However, resort to it only if you’re stuck with just vectors and matrices. If you're using Quaternions, just build a quaternion with the required vector and angle. Quaternions are a superior alternative for storing and manipulating 3D rotations; it's compact and fast e.g. concatenating two rotations in axis-angle representation is fairly expensive, moderate with matrices but cheap in quaternions. Usually all rotation manipulations are done with quaternions and as the last step converted to matrices when uploading to the rendering pipeline. See Understanding Quaternions for a decent primer on quaternions.

$('img.conversation_img[alt="example"]')
    .each(function(){
         alert($(this).attr('src'))
    });

This will display src attributes of all images of class 'conversation_img' with alt='example'

TRUNC(aDate, 'DD') will truncate the min, sec and hrs

IF your data won't overflow 4000 characters AND you're on SQL Server 2000 or compatibility level of 8 or SQL Server 2000:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(4000)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

For SQL Server 2005+:

UPDATE [CMS_DB_test].[dbo].[cms_HtmlText] 
SET Content = CAST(REPLACE(CAST(Content as NVarchar(MAX)),'ABC','DEF') AS NText)
WHERE Content LIKE '%ABC%' 

I noticed that at least two proposed solutions don't handle overlapping search hits. I didn't check the one marked with the green checkmark. Here is one that handles overlapping search hits:

    public static List<int> GetPositions(this string source, string searchString)
    {
        List<int> ret = new List<int>();
        int len = searchString.Length;
        int start = -1;
        while (true)
        {
            start = source.IndexOf(searchString, start +1);
            if (start == -1)
            {
                break;
            }
            else
            {
                ret.Add(start);
            }
        }
        return ret;
    }

Simply put list(yourQuerySet).

Here is a simple analogy; Imagine you are downloading movies online, with O(1), if it takes 5 minutes to download one movie, it will still take the same time to download 20 movies. So it doesn't matter how many movies you are downloading, they will take the same time(5 minutes) whether it's one or 20 movies. A normal example of this analogy is when you go to a movie library, whether you are taking one movie or 5, you will simply just pick them at once. Hence spending the same time.

However, with O(n), if it takes 5 minutes to download one movie, it will take about 50 minutes to download 10 movies. So time is not constant or is somehow proportional to the number of movies you are downloading.

Use the below where x is the variable which holds the markup in question.

$(x).find("div").html();

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

Inside Eclipse I've used the Clay plugin (ex Clay-Azurri). The free version allows to introspect ("reverse engineer") an existing DB schema (via JDBC) and make a diagram of some selected tables.

You should always do server side validaton as well.

public bool IsValidEmailAddress(string email)
{
    try
    {
        var emailChecked = new System.Net.Mail.MailAddress(email);
        return true;
    }
    catch
    {
        return false;
    }
}

UPDATE

You can also use the EmailAddressAttribute in System.ComponentModel.DataAnnotations. Then there is no need for a try-catch to it's a cleaner solution.

public bool IsValidEmailAddress(string email)
{
    if (!string.IsNullOrEmpty(email) && new EmailAddressAttribute().IsValid(email))
        return true;
    else
        return false;
}

Note that the IsNullOrEmpty check is also needed otherwise a null value will return true.

In my case, i only needed it within certain conditions, and to be done easily in HTML:

<input type="checkbox" [style.pointer-events]="(condition == true) ? 'none' : 'auto'"> 

Or in case you need this consistently:

<input type="checkbox" style="pointer-events: none;">

Does that work in IE6?

No, IE6 does not support attribute selectors at all, cf. CSS Compatibility and Internet Explorer.

You might find How to workaround: IE6 does not support CSS “attribute” selectors worth the read.

EDIT
If you are to ignore IE6, you could do (CSS2.1):

input[type=submit][disabled=disabled],
button[disabled=disabled] {
    ...
}

CSS3 (IE9+):

input[type=submit]:disabled,
button:disabled {
    ...
}

You can substitute [disabled=disabled] (attribute value) with [disabled] (attribute presence).

    static void Main(string[] args)

        BaseClient clientbase = new BaseClient("https://website.com/api/v2/", "username", "password");

If you truly want to discard the commits you've made locally, i.e. never have them in the history again, you're not asking how to pull - pull means merge, and you don't need to merge. All you need do is this:

# fetch from the default remote, origin
git fetch
# reset your current branch (master) to origin's master
git reset --hard origin/master

I'd personally recommend creating a backup branch at your current HEAD first, so that if you realize this was a bad idea, you haven't lost track of it.

If on the other hand, you want to keep those commits and make it look as though you merged with origin, and cause the merge to keep the versions from origin only, you can use the ours merge strategy:

# fetch from the default remote, origin
git fetch
# create a branch at your current master
git branch old-master
# reset to origin's master
git reset --hard origin/master
# merge your old master, keeping "our" (origin/master's) content
git merge -s ours old-master

From ?read.table: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.

So, perhaps your data file isn't clean. Being more specific will help the data import:

d = read.table("foobar.txt", 
               sep="\t", 
               col.names=c("id", "name"), 
               fill=FALSE, 
               strip.white=TRUE)

will specify exact columns and fill=FALSE will force a two column data frame.

In Windows 10 Mail, you might need to add these in your html head:

<!--[if (mso)|(mso 16)]>
  <style type="text/css">
    body, table, td, a, span { font-family: Arial, Helvetica, sans-serif !important; }
    a {text-decoration: none;}
  </style>
<![endif]-->

The 'a {text-decoration: none;}' fixed the underline problems :)

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}

Jeremy Keith (@adactio) has a good solution for this on his blog Orientation and scale

Keep the Markup scalable by not setting a maximum-scale in markup.

<meta name="viewport" content="width=device-width, initial-scale=1">

Then disable scalability with javascript on load until gesturestart when you allow scalability again with this script:

if (navigator.userAgent.match(/iPhone/i) || navigator.userAgent.match(/iPad/i)) {
    var viewportmeta = document.querySelector('meta[name="viewport"]');
    if (viewportmeta) {
        viewportmeta.content = 'width=device-width, minimum-scale=1.0, maximum-scale=1.0, initial-scale=1.0';
        document.body.addEventListener('gesturestart', function () {
            viewportmeta.content = 'width=device-width, minimum-scale=0.25, maximum-scale=1.6';
        }, false);
    }
}

Update 22-12-2014:
On an iPad 1 this doesnt work, it fails on the eventlistener. I've found that removing .body fixes that:

document.addEventListener('gesturestart', function() { /* */ });

I think we can modify the UsedRange code from @Readify's answer above to get the last used column even if the starting columns are blank or not.

So this lColumn = ws.UsedRange.Columns.Count modified to

this lColumn = ws.UsedRange.Column + ws.UsedRange.Columns.Count - 1 will give reliable results always

?Sheet1.UsedRange.Column + Sheet1.UsedRange.Columns.Count - 1

Above line Yields 9 in the immediate window.

You can use .html() to get content of span and or div elements.

example:

    var monthname =  $(this).html();
    alert(monthname);

Okay, as of 0.7.7 this is available, but not in the manner that lubar describes. I ended up needing to parse through some commit logs on git hub to figure this one out, but the following code does actually work for me now:

var io = require('socket.io').listen(server);

io.sockets.on('connection', function (socket) {
  var address = socket.handshake.address;
  console.log('New connection from ' + address.address + ':' + address.port);
});

I have 3 fields to fetch from Oracle Database,Which is for Forex and Currency Application.

SELECT BUY.RATE FROM FRBU.CURRENCY WHERE CURRENCY.MARKET =10 AND CURRENCY.CODE IN (‘USD’, ’AUD’, ‘SGD’)

If its windows 2003 / IIS 6.0 then check out AspMaxRequestEntityAllowed = "204800" in the file metabase.xml located in folder C:\windows\system32\inetsrv\

The default value of "204800" (~205Kb) is in my opinion too low for most users. Just change the value to what you think should be max.

If you cant save the file after editing it you have to either stop the ISS-server or enable the server to allow editing of the file:

_{(source: itmaskinen.se)}

Edit: I did not read the question correct (how to set the maxrequest in webconfig). But this informatin may be of interrest for other people, many people who move their sites from win2000-server to win2003 and had a working upload-function and suddenly got the Request.BinaryRead Failed error will have use of it. So I leave the answer here.

Arrays.asList() would do the trick here.

String[] words = {"ace", "boom", "crew", "dog", "eon"};   

List<String> wordList = Arrays.asList(words);  

For converting to Set, you can do as below

Set<T> mySet = new HashSet<T>(Arrays.asList(words)); 

Set private int selected_position = -1; to prevent from any item being selected on start.

 @Override
 public void onBindViewHolder(final OrdersHolder holder, final int position) {
    final Order order = orders.get(position);
    holder.bind(order);
    if(selected_position == position){
        //changes background color of selected item in RecyclerView
        holder.itemView.setBackgroundColor(Color.GREEN);
    } else {
        holder.itemView.setBackgroundColor(Color.TRANSPARENT);
        //this updated an order property by status in DB
        order.setProductStatus("0");
    }
    holder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            //status switch and DB update
            if (order.getProductStatus().equals("0")) {
                order.setProductStatus("1");
                notifyItemChanged(selected_position);
                selected_position = position;
                notifyItemChanged(selected_position);
             } else {
                if (order.getProductStatus().equals("1")){
                    //calls for interface implementation in
                    //MainActivity which opens a new fragment with 
                    //selected item details 
                    listener.onOrderSelected(order);
                }
             }
         }
     });
}

The biggest difference is their functionality. push_back always puts a new element at the end of the vector and insert allows you to select new element's position. This impacts the performance. vector elements are moved in the memory only when it's necessary to increase it's length because too little memory was allocated for it. On the other hand insert forces to move all elements after the selected position of a new element. You simply have to make a place for it. This is why insert might often be less efficient than push_back.

To use Lambda expression you need to either create your own functional interface or use Java functional interface for operation that require two integer and return as value. IntBinaryOperator

Using user defined functional interface

interface TwoArgInterface {

    public int operation(int a, int b);
}

public class MyClass {

    public static void main(String javalatte[]) {
        // this is lambda expression
        TwoArgInterface plusOperation = (a, b) -> a + b;
        System.out.println("Sum of 10,34 : " + plusOperation.operation(10, 34));

    }
}

Using Java functional interface

import java.util.function.IntBinaryOperator;

public class MyClass1 {

    static void main(String javalatte[]) {
        // this is lambda expression
        IntBinaryOperator plusOperation = (a, b) -> a + b;
        System.out.println("Sum of 10,34 : " + plusOperation.applyAsInt(10, 34));

    }
}

Something like this should do the trick:

$(document).ready(function() {
    $('#toptitle').text(function(i, oldText) {
        return oldText === 'Profil' ? 'New word' : oldText;
    });
});

This only replaces the content when it is Profil. See text in the jQuery API.

On Linux you can also use:

struct timeval timeout;
timeout.tv_sec  = 7;  // after 7 seconds connect() will timeout
timeout.tv_usec = 0;
setsockopt(fd, SOL_SOCKET, SO_SNDTIMEO, &timeout, sizeof(timeout));
connect(...)

Don't forget to clear SO_SNDTIMEO after connect() if you don't need it.

We were trying to avoid using the IE specific

$window[0].document.body.clientHeight 

And found that the following jQuery will not consistently yield the same value but eventually does at some point in our page load scenario which worked for us and maintained cross-browser support:

$(document).height()

open windows powershell, run as administrater and SetExecution policy as Unrestricted then it will work.

I am sharing our nodejs implementation of the solution as implemented by @Raymond Hettinger.

var crypto = require('crypto');
var s = 'she sells sea shells by the sea shore';
console.log(BigInt('0x' + crypto.createHash('sha1').update(s).digest('hex'))%(10n ** 8n));

.NET is seeing an invalid SSL certificate on the other end of the connection. There is a workaround for it, but obviously not recommended for production code:

// Put this somewhere that is only once - like an initialization method
ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateCertificate);
...

static bool ValidateCertificate(object sender, X509Certificate certificate, X509Chain chain, SslPolicyErrors errors)
{
   return true;
}

df[df['ids'].str.contains('ball', na = False)] # valid for (at least) pandas version 0.17.1

Step-by-step explanation (from inner to outer):

• df['ids'] selects the ids column of the data frame (technically, the object df['ids'] is of type pandas.Series)
• df['ids'].str allows us to apply vectorized string methods (e.g., lower, contains) to the Series
• df['ids'].str.contains('ball') checks each element of the Series as to whether the element value has the string 'ball' as a substring. The result is a Series of Booleans indicating True or False about the existence of a 'ball' substring.
• df[df['ids'].str.contains('ball')] applies the Boolean 'mask' to the dataframe and returns a view containing appropriate records.
• na = False removes NA / NaN values from consideration; otherwise a ValueError may be returned.

You can't set colour of the padding.

You will have to create a wrapper element with the desired background colour. Add border to this element and set it's padding.

Look here for an example: http://jsbin.com/abanek/1/edit

An activity populates the ActionBar in its onCreateOptionsMenu() method.

Instead of using setcustomview(), just override onCreateOptionsMenu like this:

@Override    
public boolean onCreateOptionsMenu(Menu menu) {
  MenuInflater inflater = getMenuInflater();
  inflater.inflate(R.menu.mainmenu, menu);
  return true;
}

If an actions in the ActionBar is selected, the onOptionsItemSelected() method is called. It receives the selected action as parameter. Based on this information you code can decide what to do for example:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
  switch (item.getItemId()) {
    case R.id.menuitem1:
      Toast.makeText(this, "Menu Item 1 selected", Toast.LENGTH_SHORT).show();
      break;
    case R.id.menuitem2:
      Toast.makeText(this, "Menu item 2 selected", Toast.LENGTH_SHORT).show();
      break;
  }
  return true;
}

Looks like the answer above was a little incomplete try the following:-

=RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))

Obviously, this is for cell A2...

What this does is uses a combination of Right and Len - Len is the length of a string and in this case, we want to remove all but one from that... clearly, if you wanted the last two characters you'd change the -1 to -2 etc etc etc.

After the length has been determined and the portion of that which is required - then the Right command will display the information you need.

This works well combined with an IF statement - I use this to find out if the last character of a string of text is a specific character and remove it if it is. See, the example below for stripping out commas from the end of a text string...

=IF(RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))=",",LEFT(A2,(LEN(A2)-1)),A2)

Unless you have more style sheets than that, you've messed up your break points:

#1 (max-width: 700px)
#2 (min-width: 701px) and (max-width: 900px)
#3 (max-width: 901px)

The 3rd media query is probably meant to be min-width: 901px. Right now, it overlaps #1 and #2, and only controls the page layout by itself when the screen is exactly 901px wide.

Edit for updated question:

(max-width: 640px)
(max-width: 800px)
(max-width: 1024px)
(max-width: 1280px)

Media queries aren't like catch or if/else statements. If any of the conditions match, then it will apply all of the styles from each media query it matched. If you only specify a min-width for all of your media queries, it's possible that some or all of the media queries are matched. In your case, a device that's 640px wide matches all 4 of your media queries, so all for style sheets are loaded. What you are most likely looking for is this:

(max-width: 640px)
(min-width: 641px) and (max-width: 800px)
(min-width: 801px) and (max-width: 1024px)
(min-width: 1025px)

Now there's no overlap. The styles will only apply if the device's width falls between the widths specified.

I'm going to guess you aren't getting errors or you would've mentioned them. If that's the case, try removing the href attribute value so the page doesn't navigate away before your code is executed. In Angular it's perfectly acceptable to leave href attributes blank.

<a href="" data-router="article" ng-click="changeListName('metro')">

Also I don't know what data-router is doing but if you still aren't getting the proper result, that could be why.

The best solution I found for this is actually not to use a Spinner but an AutoCompleteTextView. Its basically an EditText with attached Spinner to show suggestions as you type - but, with the right config, it can behave exactly as the OP wishes and more.

XML:

<com.google.android.material.textfield.TextInputLayout
                android:id="@+id/item"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

            <androidx.appcompat.widget.AppCompatAutoCompleteTextView
                    android:id="@+id/input"
                    android:hint="Select one"
                    style="@style/AutoCompleteTextViewDropDown"/>
        </com.google.android.material.textfield.TextInputLayout>

Style:

<style name="AutoCompleteTextViewDropDown">
    <item name="android:clickable">false</item>
    <item name="android:cursorVisible">false</item>
    <item name="android:focusable">false</item>
    <item name="android:focusableInTouchMode">false</item>
    <item name="android:layout_width">match_parent</item>
    <item name="android:layout_height">wrap_content</item>
</style>

As for the adapter use the basic ArrayAdapter or extend it to make your own, but no additional customization on the adapter side is necessary. Set the adapter on the AutoCompleteTextView.

You can't follow the cursor with a DIV, but you can draw a DIV when moving the cursor!

$(document).on('mousemove', function(e){
    $('#your_div_id').css({
       left:  e.pageX,
       top:   e.pageY
    });
});

That div must be off the float, so position: absolute should be set.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

Actually, you can save you picture at any place. If you want to save in a public space, so any other application can access, use this code:

storageDir = new File(
    Environment.getExternalStoragePublicDirectory(
        Environment.DIRECTORY_PICTURES
    ), 
    getAlbumName()
);

The picture doesn't go to the album. To do this, you need to call a scan:

private void galleryAddPic() {
    Intent mediaScanIntent = new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE);
    File f = new File(mCurrentPhotoPath);
    Uri contentUri = Uri.fromFile(f);
    mediaScanIntent.setData(contentUri);
    this.sendBroadcast(mediaScanIntent);
}

You can found more info at https://developer.android.com/training/camera/photobasics.html#TaskGallery

In python "else if" is spelled "elif".
Also, you need a colon after the elif and the else.

Simple answer to a simple question. I had the same problem, when I first started (in the last couple of weeks).

So your code should read:

def function(a):
    if a == '1':
        print('1a')
    elif a == '2':
        print('2a')
    else:
        print('3a')

function(input('input:'))

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!
