Jerker's answer is little simpler. Here's sample code which works from MS:

var folder = new Shell().NameSpace(folderPath);
foreach (FolderItem2 item in folder.Items())
{
    var company = item.ExtendedProperty("Company");
    var author = item.ExtendedProperty("Author");
    // Etc.
}

For those who can't reference shell32 statically, you can invoke it dynamically like this:

var shellAppType = Type.GetTypeFromProgID("Shell.Application");
dynamic shellApp = Activator.CreateInstance(shellAppType);
var folder = shellApp.NameSpace(folderPath);
foreach (var item in folder.Items())
{
    var company = item.ExtendedProperty("Company");
    var author = item.ExtendedProperty("Author");
    // Etc.
}

I also faced same issue after doing composer update

I tried installing composer required monolog/monolog too but didn't work.

Then I removed the /vendor directory and ran composer install and worked as per normal.

basically it must have reverted my monolog and other stable packages version back to previous. so better not to composer update

what I noticed comparing both the /vendor folders and found those classes files under /vendor/monolog/monolog/src/Handler were missing after composer updated.

if you need more speed and less accuracy then you could use raw lxml.

import lxml.html as lh
from lxml.html.clean import clean_html

def lxml_to_text(html):
    doc = lh.fromstring(html)
    doc = clean_html(doc)
    return doc.text_content()

Just for completion, here is a code example indicating the differences:

success \ error:

$http.get('/someURL')
.success(function(data, status, header, config) {
    // success handler
})
.error(function(data, status, header, config) {
    // error handler
});

then:

$http.get('/someURL')
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
})
.then(function(response) {
    // success handler
}, function(response) {
    // error handler
}).

File file = context.getFilesDir(); 
file.mkdir();
String[] array = filePath.split("/"); 
for(int t = 0; t < array.length - 1; t++) {
    file = new File(file, array[t]); 
    file.mkdir();
}
File f = new File(file,array[array.length- 1]); 
RandomAccessFileOutputStream rvalue = 
    new RandomAccessFileOutputStream(f, append);

public Bitmap resizeBitmap(String photoPath, int targetW, int targetH) {
    BitmapFactory.Options bmOptions = new BitmapFactory.Options();
    bmOptions.inJustDecodeBounds = true;
    BitmapFactory.decodeFile(photoPath, bmOptions);
    int photoW = bmOptions.outWidth;
    int photoH = bmOptions.outHeight;

    int scaleFactor = 1;
    if ((targetW > 0) || (targetH > 0)) {
            scaleFactor = Math.min(photoW/targetW, photoH/targetH);        
    }

    bmOptions.inJustDecodeBounds = false;
    bmOptions.inSampleSize = scaleFactor;
    bmOptions.inPurgeable = true; //Deprecated API 21

    return BitmapFactory.decodeFile(photoPath, bmOptions);            
}

HotelsCombined has an easy-to-access and useful service to download the data feed files with hotels. Not exactly API, but something you can get, parse and use. Here is how you do it:

1. Go to http://www.hotelscombined.com/Affiliates.aspx
2. Register there (no company or bank data is needed)
3. Open “Data feeds” page
4. Choose “Standard data feed” -> “Single file” -> “CSV format” (you may get XML as well)

If you are interested in details, you may find the sample Python code to filter CSV file to get hotels for a specific city here:

http://mikhail.io/2012/05/17/api-to-get-the-list-of-hotels/

Update:

Unfortunately, HotelsCombined.com has introduced the new regulations: they've restricted the access to data feeds by default. To get the access, a partner must submit some information on why one needs the data. The HC team will review it and then (maybe) will grant access.

You have to put a space between {} and \;

So the command will be like:

find /home/me/download/ -type f -name "*.rm" -exec ffmpeg -i {} -sameq {}.mp3 && rm {} \;

For long, I used to use the approach mentioned in the solution here. There is a concern however, about security of the secrets in clear text. You can use another package on top of config so that the security bits are taken care of.

Check this out: https://www.attosol.com/secure-application-secrets-using-masterkey-in-azure-key-vault/

With ECMAScript 6 StoBor's answer can be done even more concise:

homes.sort((a, b) => a.price - b.price)

BLOB primarily intended to hold non-traditional data, such as images,videos,voice or mixed media. CLOB intended to retain character-based data.

One other thing that can cause "ambiguous redirect" is \t \n \r in the variable name you are writing too

Maybe not \n\r? But err on the side of caution

Try this

echo "a" > ${output_name//[$'\t\n\r']}

I got hit with this one while parsing HTML, Tabs \t at the beginning of the line.

You can take advantage of CSS3 to do that, by hidding the by-default input radio button with CSS3 rules:

.class-selector input{
    margin:0;padding:0;
    -webkit-appearance:none;
       -moz-appearance:none;
            appearance:none;
}

And then using labels for images as the following demos:

To make the child element positioned absolutely from its parent element you need to set relative position on the parent element AND absolute position on the child element.

Then on the child element 'top' is relative to the height of the parent. So you also need to 'translate' upward the child 50% of its own height.

.base{_x000D_
    background-color: green;_x000D_
    width: 200px;_x000D_
    height: 200px;_x000D_
    overflow: auto;_x000D_
    position: relative;_x000D_
}_x000D_
    _x000D_
.vert-align {_x000D_
    position: absolute;_x000D_
    top: 50%;_x000D_
    transform: translate(0, -50%);_x000D_
}

    <div class="base">_x000D_
        <div class="vert-align">_x000D_
            Content Here_x000D_
        </div>_x000D_
    </div>

There is another a solution using flex box.

.base{_x000D_
    background-color:green;_x000D_
    width: 200px;_x000D_
    height: 200px;_x000D_
    overflow: auto;_x000D_
    display: flex;_x000D_
    align-items: center;_x000D_
}

<div class="base">_x000D_
    <div class="vert-align">_x000D_
        Content Here_x000D_
    </div>_x000D_
</div>

You will find advantages/disavantages for both.

A portion of code originally from Example Depot for listing all of the aliases in a key store:

    // Load input stream into keystore
    keystore.load(is, password.toCharArray());

    // List the aliases
    Enumeration aliases = keystore.aliases();
    for (; aliases.hasMoreElements(); ) {
        String alias = (String)aliases.nextElement();

        // Does alias refer to a private key?
        boolean b = keystore.isKeyEntry(alias);

        // Does alias refer to a trusted certificate?
        b = keystore.isCertificateEntry(alias);
    }

The exporting of private keys came up on the Sun forums a couple of months ago, and u:turingcompleter came up with a DumpPrivateKey class to stitch into your app.

import java.io.FileInputStream;
import java.security.Key;
import java.security.KeyStore;
import sun.misc.BASE64Encoder;

public class DumpPrivateKey {
     /**

     * that Apache needs for SSLCertificateKeyFile.

     *              <li> [2] alias
     *              </ul>
     */
    static public void main(String[] args)
    throws Exception {
        if(args.length < 3) {
          throw new IllegalArgumentException("expected args: Keystore filename, Keystore password, alias, <key password: default same tha
n keystore");
        }
        final String keystoreName = args[0];
        final String keystorePassword = args[1];
        final String alias = args[2];
        final String keyPassword = getKeyPassword(args,keystorePassword);
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(new FileInputStream(keystoreName), keystorePassword.toCharArray());
        Key key = ks.getKey(alias, keyPassword.toCharArray());
        String b64 = new BASE64Encoder().encode(key.getEncoded());
        System.out.println("-----BEGIN PRIVATE KEY-----");
        System.out.println(b64);
        System.out.println("-----END PRIVATE KEY-----");
    }
    private static String getKeyPassword(final String[] args, final String keystorePassword)
    {
       String keyPassword = keystorePassword; // default case
       if(args.length == 4) {
         keyPassword = args[3];
       }
       return keyPassword;
    }
}

Note: this use Sun package, which is a "bad thing".
If you can download apache commons code, here is a version which will compile without warning:

javac -classpath .:commons-codec-1.4/commons-codec-1.4.jar DumpPrivateKey.java

and will give the same result:

import java.io.FileInputStream;
import java.security.Key;
import java.security.KeyStore;
//import sun.misc.BASE64Encoder;
import org.apache.commons.codec.binary.Base64;

public class DumpPrivateKey {

        }
        final String keystoreName = args[0];
        final String keystorePassword = args[1];
        final String alias = args[2];
        final String keyPassword = getKeyPassword(args,keystorePassword);
        KeyStore ks = KeyStore.getInstance("jks");
        ks.load(new FileInputStream(keystoreName), keystorePassword.toCharArray());
        Key key = ks.getKey(alias, keyPassword.toCharArray());
        //String b64 = new BASE64Encoder().encode(key.getEncoded());
        String b64 = new String(Base64.encodeBase64(key.getEncoded(),true));
        System.out.println("-----BEGIN PRIVATE KEY-----");
        System.out.println(b64);
        System.out.println("-----END PRIVATE KEY-----");
    }
    private static String getKeyPassword(final String[] args, final String keystorePassword)
    {
       String keyPassword = keystorePassword; // default case
       if(args.length == 4) {
         keyPassword = args[3];
       }
       return keyPassword;
    }
}

You can use it like so:

java -classpath .:commons-codec-1.4/commons-codec-1.4.jar DumpPrivateKey $HOME/.keystore changeit tomcat

I know this question is pretty old now, but I thought you might have an easier time with ElementTree

from xml.etree import ElementTree as ET
import datetime

f = ET.XML(data)

for element in f:
    if element.tag == "currentTime":
        # Handle time data was pulled
        currentTime = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "cachedUntil":
        # Handle time until next allowed update
        cachedUntil = datetime.datetime.strptime(element.text, "%Y-%m-%d %H:%M:%S")
    if element.tag == "result":
        # Process list of skills
        pass

I know that's not super specific, but I just discovered it, and so far it's a lot easier to get my head around than the minidom (since so many nodes are essentially white space).

For instance, you have the tag name and the actual text together, just as you'd probably expect:

>>> element[0]
<Element currentTime at 40984d0>
>>> element[0].tag
'currentTime'
>>> element[0].text
'2010-04-12 02:45:45'e

You have your ssh clone statement wrong: git clone username [email protected]:root/test.git

That statement would try to clone a repository named username into the location relative to your current path, [email protected]:root/test.git.

You want to leave out username:

git clone [email protected]:root/test.git

I had same problem, I solved this problem by following way.

Right click on page, select Property. in build action select Content.

Hope that this solution may help you.

You will have the same object two times in your array, because object values are passed by reference. You have to create a new object like this

myElement.id = 244;
myElement.value = 3556;
myArray[0] = $.extend({}, myElement); //for shallow copy or
myArray[0] = $.extend(true, {}, myElement); // for deep copy

or

myArray.push({ id: 24, value: 246 });

assign is good, but I have not found a function for referring back to the variable you've created in an automated script. (as.name seems to work the opposite way). More experienced coders will doubtless have a better solution, but this solution works and is slightly humorous perhaps, in that it gets R to write code for itself to execute.

Say I have just assigned value 5 to x (var.name <- "x"; assign(var.name, 5)) and I want to change the value to 6. If I am writing a script and don't know in advance what the variable name (var.name) will be (which seems to be the point of the assign function), I can't simply put x <- 6 because var.name might have been "y". So I do:

var.name <- "x"
#some other code...
assign(var.name, 5)
#some more code...

#write a script file (1 line in this case) that works with whatever variable name
write(paste0(var.name, " <- 6"), "tmp.R")
#source that script file
source("tmp.R")
#remove the script file for tidiness
file.remove("tmp.R")

x will be changed to 6, and if the variable name was anything other than "x", that variable will similarly have been changed to 6.

Because otherwise scanf will think you are passing a pointer to a float which is a smaller size than a double, and it will return an incorrect value.

Hope this will help someone.

 public static String getDate(
        String date, String currentFormat, String expectedFormat)
throws ParseException {
    // Validating if the supplied parameters is null 
    if (date == null || currentFormat == null || expectedFormat == null ) {
        return null;
    }
    // Create SimpleDateFormat object with source string date format
    SimpleDateFormat sourceDateFormat = new SimpleDateFormat(currentFormat);
    // Parse the string into Date object
    Date dateObj = sourceDateFormat.parse(date);
    // Create SimpleDateFormat object with desired date format
    SimpleDateFormat desiredDateFormat = new SimpleDateFormat(expectedFormat);
    // Parse the date into another format
    return desiredDateFormat.format(dateObj).toString();
}

I've encountered string, which had mixings of English, Russian and some other alphabets, which caused exception. I need only Russian and English, and this currently works for me:

ec1 = Encoding::Converter.new "UTF-8","Windows-1251",:invalid=>:replace,:undef=>:replace,:replace=>""
ec2 = Encoding::Converter.new "Windows-1251","UTF-8",:invalid=>:replace,:undef=>:replace,:replace=>""
t = ec2.convert ec1.convert t

I find dstat to be quite good. Has to be installed though. Gives you way more information than you need. Netstat will give you packet rates but not bandwith also. netstat -s

you can use Package Manager to add it as package and it is the easiest way to do. You don't need anything else to work with mysql database.

Or you can run below command in Package Manager Console

PM> Install-Package MySql.Data

NUGET Mysql.Data

What is the code of your button? If it's an a tag, then you could do this:

a {_x000D_
  padding: 5px;_x000D_
  background: green;_x000D_
}_x000D_
a:visited {_x000D_
  background: red;_x000D_
}

<a href="#">A button</a>

Or you could use jQuery to add a class on click, as below:

$("#button").click(function() {_x000D_
  $("#button").addClass('button-clicked');_x000D_
});

.button-clicked {_x000D_
  background: red;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<button id="button">Button</button>

using DB facade you can perform SQL queries

 public function index()
{
    return DB::table('table_name')->get();
}

the first two bounds default to 0 and the length of the sequence, as before, and a stride of -1 indicates that the slice should go from right to left instead of the usual left to right. The effect, therefore, is to reverse the sequence.

name="ravi"
print(name[::-1]) #ivar

Thanks everyone for the answers. Another quick solution will be to use jQuery.param method with traditional parameter set to true to convert JSON object to string:

$.post("/your/url", $.param(yourJsonObject,true));

FYI, I put together a JSFiddle of this using the $cookieStore, two controllers, a $rootScope, and AngularjS 1.0.6. It's on JSFifddle as http://jsfiddle.net/krimple/9dSb2/ as a base if you're messing around with this...

The gist of it is:

Javascript

var myApp = angular.module('myApp', ['ngCookies']);

myApp.controller('CookieCtrl', function ($scope, $rootScope, $cookieStore) {
    $scope.bump = function () {
        var lastVal = $cookieStore.get('lastValue');
        if (!lastVal) {
            $rootScope.lastVal = 1;
        } else {
            $rootScope.lastVal = lastVal + 1;
        }
        $cookieStore.put('lastValue', $rootScope.lastVal);
    }
});

myApp.controller('ShowerCtrl', function () {
});

HTML

<div ng-app="myApp">
    <div id="lastVal" ng-controller="ShowerCtrl">{{ lastVal }}</div>
    <div id="button-holder" ng-controller="CookieCtrl">
        <button ng-click="bump()">Bump!</button>
    </div>
</div>

Use comma separated values as below.

$email_to = 'Mary <[email protected]>, Kelly <[email protected]>';
@mail($email_to, $email_subject, $email_message, $headers);

or run a foreach for email address

//list of emails in array format and each one will see their own to email address
$arrEmail = array('Mary <[email protected]>', 'Kelly <[email protected]>');

foreach($arrEmail as $key => $email_to)
    @mail($email_to, $email_subject, $email_message, $headers);

cat("\014") . This will work. no worries

Just to elaborate on what others have said, multiple CSS classes are combined in a single string, delimited by spaces. Thus, if you wanted to hard-code it, it would simply look like this:

<div class="someClass otherClass yetAnotherClass">
      <img ... id="image1" name="image1" />
</div>

From there you can easily derive the javascript necessary to add a new class... just append a space followed by the new class to the element's className property. Knowing this, you can also write a function to remove a class later should the need arise.

You have misunderstood the Python list object. It is similar to a C pointer-array. It does not actually "copy" the object which you append to it. Instead, it just store a "pointer" to that object.

Try the following code:

>>> d={}
>>> dlist=[]
>>> for i in xrange(0,3):
    d['data']=i
    dlist.append(d)
    print(d)

{'data': 0}
{'data': 1}
{'data': 2}
>>> print(dlist)
[{'data': 2}, {'data': 2}, {'data': 2}]

So why is print(dlist) not the same as print(d)?

The following code shows you the reason:

>>> for i in dlist:
    print "the list item point to object:", id(i)

the list item point to object: 47472232
the list item point to object: 47472232
the list item point to object: 47472232

So you can see all the items in the dlist is actually pointing to the same dict object.

The real answer to this question will be to append the "copy" of the target item, by using d.copy().

>>> dlist=[]
>>> for i in xrange(0,3):
    d['data']=i
    dlist.append(d.copy())
    print(d)

{'data': 0}
{'data': 1}
{'data': 2}
>>> print dlist
[{'data': 0}, {'data': 1}, {'data': 2}]

Try the id() trick, you can see the list items actually point to completely different objects.

>>> for i in dlist:
    print "the list item points to object:", id(i)

the list item points to object: 33861576
the list item points to object: 47472520
the list item points to object: 47458120

I face same error for ejs, then i just run node install ejs This will install ejs again.

and then also run npm install to install node_modules again. That's work for me.

You just can put your query as a subquery:

SELECT avg(count)
  FROM 
    (
    SELECT COUNT (*) AS Count
      FROM Table T
     WHERE T.Update_time =
               (SELECT MAX (B.Update_time )
                  FROM Table B
                 WHERE (B.Id = T.Id))
    GROUP BY T.Grouping
    ) as counts

Edit: I think this should be the same:

SELECT count(*) / count(distinct T.Grouping)
  FROM Table T
 WHERE T.Update_time =
           (SELECT MAX (B.Update_time)
              FROM Table B
             WHERE (B.Id = T.Id))

Put this at the top of your file:

$Logfile = "D:\Apps\Logs\$(gc env:computername).log"

Function LogWrite
{
   Param ([string]$logstring)

   Add-content $Logfile -value $logstring
}

Then replace your Write-host calls with LogWrite.

By Running this command you'll get the most recent tag that usually is the version of your project:

git describe --abbrev=0 --tags

If you are using an emulator for testing then you must use <uses-permission android:name="android.permission.INTERNET" />only and ignore <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />.It's work for me.

The following should work in an angular CLI 6 project. I.e if you are getting:

get/set have been deprecated in favor of the config command.

npm install node-sass --save-dev

Then (making sure you change the project name)

ng config projects.YourPorjectName.schematics.@schematics/angular:component.styleext sass

To get your default project name use:

ng config defaultProject

However: If you have migrated your project from <6 up to angular 6 there is a good chance that the config wont be there. In which case you might get:

Invalid JSON character: "s" at 0:0

Therefore a manual editing of angular.json will be required.

You will want it to look something like this (taking note of the styleex property):

...
"projects": {
    "Sassy": {
      "root": "",
      "sourceRoot": "src",
      "projectType": "application",
      "prefix": "app",
      "schematics": {
        "@schematics/angular:component": {
          "styleext": "scss"
        }
      }
...

Seems like an overly complex schema to me. ¯_(?)_/¯

You will now have to go and change all your css/less files to be scss and update any references in components etc, but you should be good to go.

The method which you are using is rendering login button from the Facebook Javascript code. However, you can write your own Javascript code function to mimic the functionality. Here is how to do it -

1. Create a simple anchor tag link with the image you want to show. Have a onclick method on anchor tag which would actually do the real job.

<a href="#" onclick="fb_login();"><img src="images/fb_login_awesome.jpg" border="0" alt=""></a>

2. Next, we create the Javascript function which will show the actual popup and will fetch the complete user information, if user allows. We also handle the scenario if user disallows our facebook app.

window.fbAsyncInit = function() {
    FB.init({
        appId   : 'YOUR_APP_ID',
        oauth   : true,
        status  : true, // check login status
        cookie  : true, // enable cookies to allow the server to access the session
        xfbml   : true // parse XFBML
    });

  };

function fb_login(){
    FB.login(function(response) {

        if (response.authResponse) {
            console.log('Welcome!  Fetching your information.... ');
            //console.log(response); // dump complete info
            access_token = response.authResponse.accessToken; //get access token
            user_id = response.authResponse.userID; //get FB UID

            FB.api('/me', function(response) {
                user_email = response.email; //get user email
          // you can store this data into your database             
            });

        } else {
            //user hit cancel button
            console.log('User cancelled login or did not fully authorize.');

        }
    }, {
        scope: 'public_profile,email'
    });
}
(function() {
    var e = document.createElement('script');
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    e.async = true;
    document.getElementById('fb-root').appendChild(e);

3. We are done.

Please note that the above function is fully tested and works. You just need to put your facebook APP ID and it will work.

Just to point onto the example posted by Mathew

public sealed class Singleton
{
    // Because Singleton's constructor is private, we must explicitly
    // give the Lazy<Singleton> a delegate for creating the Singleton.
    private static readonly Lazy<Singleton> instanceHolder =
        new Lazy<Singleton>(() => new Singleton());

    private Singleton()
    {
        ...
    }

    public static Singleton Instance
    {
        get { return instanceHolder.Value; }
    }
}

before the Lazy was born we would have done it this way:

private static object lockingObject = new object();
public static LazySample InstanceCreation()
{
    if(lazilyInitObject == null)
    {
         lock (lockingObject)
         {
              if(lazilyInitObject == null)
              {
                   lazilyInitObject = new LazySample ();
              }
         }
    }
    return lazilyInitObject ;
}

You need to find reference of existing Fragment and remove that fragment using below code. You need add/commit fragment using one tag ex. "TAG_FRAGMENT".

Fragment fragment = getSupportFragmentManager().findFragmentByTag(TAG_FRAGMENT);
if(fragment != null)
    getSupportFragmentManager().beginTransaction().remove(fragment).commit();

That is it.

<a href="http://www.google.com" class="ignore-click">Test</a>

with jQuery:

<script>
    $(".ignore-click").click(function(){
        return false;
    })
</script>

with JavaScript

<script>
        for (var i = 0; i < document.getElementsByClassName("ignore-click").length; i++) {
            document.getElementsByClassName("ignore-click")[i].addEventListener('click', function (event) {
                event.preventDefault();
                return false;
            });
        }
</script>

You assign class .ignore-click to as many elements you like and clicks on those elements will be ignored

Create a div, which contains both divs (full and someid) and set the height of that div to the following:

height: 100vh;

The height of the containing divs (full and someid) should be set to "auto". That's all.

http://en.wikipedia.org/wiki/Byte_order_mark

The byte order mark (BOM) is a Unicode character used to signal the endianness (byte order) of a text file or stream. Its code point is U+FEFF. BOM use is optional, and, if used, should appear at the start of the text stream. Beyond its specific use as a byte-order indicator, the BOM character may also indicate which of the several Unicode representations the text is encoded in.

The BOM is a funky-looking character that you sometimes find at the start of unicode streams, giving a clue what the encoding is. It's usually handles invisibly by the string-handling stuff in Java, so you must have confused it somehow, but without seeing your code, it's hard to see where.

You might be able to fix it trivially by manually stripping the BOM from the string before feeding it to javac. It probably qualifies as whitespace, so try calling trim() on the input String, and feeding the output of that to javac.

For all databases query sys.sysprocesses

SELECT * FROM sys.sysprocesses WHERE open_tran = 1

For the current database use:

DBCC OPENTRAN

Rather than keeping everything string-based, you should use a class which is designed to represent a file system path.

If you're using Java 7 or Java 8, you should strongly consider using java.nio.file.Path; Path.resolve can be used to combine one path with another, or with a string. The Paths helper class is useful too. For example:

Path path = Paths.get("foo", "bar", "baz.txt");

If you need to cater for pre-Java-7 environments, you can use java.io.File, like this:

File baseDirectory = new File("foo");
File subDirectory = new File(baseDirectory, "bar");
File fileInDirectory = new File(subDirectory, "baz.txt");

If you want it back as a string later, you can call getPath(). Indeed, if you really wanted to mimic Path.Combine, you could just write something like:

public static String combine(String path1, String path2)
{
    File file1 = new File(path1);
    File file2 = new File(file1, path2);
    return file2.getPath();
}

This code worked for me:

var updatedText = text.Normalize(NormalizationForm.FormD)
     .Where(c => CharUnicodeInfo.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)
     .ToArray();

However, please don't do this with names. It's not only an insult to people with umlauts/accents in their name, it can also be dangerously wrong in certain situations (see below). There are alternative writings instead of just removing the accent.

Furthermore, it's simply wrong and dangerous, e.g. if the user has to provide his name exactly how it occurs on the passport.

For example my name is written Zuberbühler and in the machine readable part of my passport you will find Zuberbuehler. By removing the umlaut, the name will not match with either part. This can lead to issues for the users.

You should rather disallow umlauts/accent in an input form for names so the user can write his name correctly without its umlaut or accent.

Practical example, if the web service to apply for ESTA (https://www.application-esta.co.uk/special-characters-and) would use above code instead of transforming umlauts correctly, the ESTA application would either be refused or the traveller will have problems with the American Border Control when entering the States.

Another example would be flight tickets. Assuming you have a flight ticket booking web application, the user provides his name with an accent and your implementation is just removing the accents and then using the airline's web service to book the ticket! Your customer may not be allowed to board since the name does not match to any part of his/her passport.

To run anaconda-navigator:

$ source ~/anaconda3/bin/activate root
$ anaconda-navigator

I'm trying to answer in general, not related to this question, this error generally occurs when you break a syntax in half and forget the other half. Like in my case it was:

try :
 ....

since python was searching for a

except Exception as e:
 ....

but it encountered an EOF (End Of File), hence the error. See if you can find any incomplete syntax in your code.

Other folks have suggested array_search() which gives the key of the array element where the value is found. You can ensure that the array keys are contiguous integers by using array_values():

$list = array(0=>'string1', 'foo'=>'string2', 42=>'string3');
$index = array_search('string2', array_values($list));
print "$index\n";

// result: 1

You said in your question that array_search() was no use. Can you explain why? What did you try and how did it not meet your needs?

The -I directive does the job:

gcc -Icore -Ianimator -Iimages -Ianother_dir -Iyet_another_dir my_file.c 

You can also use the direct deploy method using curl. You don't need a pom for your file for it but it will not be generated as well so if you want one, you will have to upload it separately.

Here is the command:

version=1.2.3
artefact="myartefact"
repoId=yourrepository
groupId=org.myorg
REPO_URL=http://localhost:8081/nexus

curl -u nexususername:nexuspassword --upload-file filename.tgz $REPO_URL/content/repositories/$repoId/$groupId/$artefact/$version/$artefact-$version.tgz

How to convert a number to a string in C++03

1. Do not use the itoa or itof functions because they are non-standard and therefore not portable.
   

2. Use string streams
   

    #include <sstream>  //include this to use string streams
    #include <string> 
   
   int main()
   {    
       int number = 1234;
   
       std::ostringstream ostr; //output string stream
       ostr << number; //use the string stream just like cout,
       //except the stream prints not to stdout but to a string.
   
       std::string theNumberString = ostr.str(); //the str() function of the stream 
       //returns the string.
   
       //now  theNumberString is "1234"  
   }
   

   Note that you can use string streams also to convert floating-point numbers to string, and also to format the string as you wish, just like with cout

   std::ostringstream ostr;
   float f = 1.2;
   int i = 3;
   ostr << f << " + " i << " = " << f + i;   
   std::string s = ostr.str();
   //now s is "1.2 + 3 = 4.2" 
   

   You can use stream manipulators, such as std::endl, std::hex and functions std::setw(), std::setprecision() etc. with string streams in exactly the same manner as with cout

   Do not confuse std::ostringstream with std::ostrstream. The latter is deprecated

3. Use boost lexical cast. If you are not familiar with boost, it is a good idea to start with a small library like this lexical_cast. To download and install boost and its documentation go here. Although boost isn't in C++ standard many libraries of boost get standardized eventually and boost is widely considered of the best C++ libraries.

   Lexical cast uses streams underneath, so basically this option is the same as the previous one, just less verbose.

   #include <boost/lexical_cast.hpp>
   #include <string>
   
   int main()
   {
      float f = 1.2;
      int i = 42;
      std::string sf = boost::lexical_cast<std::string>(f); //sf is "1.2"
      std::string si = boost::lexical_cast<std::string>(i); //sf is "42"
   }
   

How to convert a string to a number in C++03

1. The most lightweight option, inherited from C, is the functions atoi (for integers (alphabetical to integer)) and atof (for floating-point values (alphabetical to float)). These functions take a C-style string as an argument (const char *) and therefore their usage may be considered a not exactly good C++ practice. cplusplus.com has easy-to-understand documentation on both atoi and atof including how they behave in case of bad input. However the link contains an error in that according to the standard if the input number is too large to fit in the target type, the behavior is undefined.

   #include <cstdlib> //the standard C library header
   #include <string>
   int main()
   {
       std::string si = "12";
       std::string sf = "1.2";
       int i = atoi(si.c_str()); //the c_str() function "converts" 
       double f = atof(sf.c_str()); //std::string to const char*
   }
   

2. Use string streams (this time input string stream, istringstream). Again, istringstream is used just like cin. Again, do not confuse istringstream with istrstream. The latter is deprecated.

   #include <sstream>
   #include <string>
   int main()
   {
      std::string inputString = "1234 12.3 44";
      std::istringstream istr(inputString);
      int i1, i2;
      float f;
      istr >> i1 >> f >> i2;
      //i1 is 1234, f is 12.3, i2 is 44  
   }
   

3. Use boost lexical cast.

   #include <boost/lexical_cast.hpp>
   #include <string>
   
   int main()
   {
      std::string sf = "42.2"; 
      std::string si = "42";
      float f = boost::lexical_cast<float>(sf); //f is 42.2
      int i = boost::lexical_cast<int>(si);  //i is 42
   }       
   

   In case of a bad input, lexical_cast throws an exception of type boost::bad_lexical_cast

In ipython, I use this to print a part of the dataframe that works quite well (prints the first 100 rows):

print paramdata.head(100).to_string()

Dynamically adding directives on angularjs has two styles:

Add an angularjs directive into another directive

• inserting a new element(directive)
• inserting a new attribute(directive) to element

inserting a new element(directive)

it's simple. And u can use in "link" or "compile".

var newElement = $compile( "<div my-diretive='n'></div>" )( $scope );
$element.parent().append( newElement );

inserting a new attribute to element

It's hard, and make me headache within two days.

Using "$compile" will raise critical recursive error!! Maybe it should ignore the current directive when re-compiling element.

$element.$set("myDirective", "expression");
var newElement = $compile( $element )( $scope ); // critical recursive error.
var newElement = angular.copy(element);          // the same error too.
$element.replaceWith( newElement );

So, I have to find a way to call the directive "link" function. It's very hard to get the useful methods which are hidden deeply inside closures.

compile: (tElement, tAttrs, transclude) ->
   links = []
   myDirectiveLink = $injector.get('myDirective'+'Directive')[0] #this is the way
   links.push myDirectiveLink
   myAnotherDirectiveLink = ($scope, $element, attrs) ->
       #....
   links.push myAnotherDirectiveLink
   return (scope, elm, attrs, ctrl) ->
       for link in links
           link(scope, elm, attrs, ctrl)       

Now, It's work well.

1-firstly, drop the foreign key constraint after that drop the tables.

2-you can drop all foreign key via executing the following query:

DECLARE @SQL varchar(4000)=''
SELECT @SQL = 
@SQL + 'ALTER TABLE ' + s.name+'.'+t.name + ' DROP CONSTRAINT [' + RTRIM(f.name) +'];' + CHAR(13)
FROM sys.Tables t
INNER JOIN sys.foreign_keys f ON f.parent_object_id = t.object_id
INNER JOIN sys.schemas     s ON s.schema_id = f.schema_id

--EXEC (@SQL)

PRINT @SQL

if you execute the printed results @SQL, the foreign keys will be dropped.

I have search for this problem and i got the following answers:

1. "C:\Program Files\Apache-tomcat-7.0.69\" remove the extra backslash (\)
2. Right click the log folder in tomcat folder and in security tab give this folder as a write-permission and then restart the net-beans as an run as administrator.

Your problem will be solved

As it stands, there is no 'autocomplete off' attribute in CSS. However, html has an easy code for this:

<input type="text" id="foo" value="bar" autocomplete="off" />

If you're looking for a site-wide effector, an easy one would be to simply have a js function to run through all 'input' s and add this tag, or look for the corresponding css class / id.

The autocomplete attribute works fine in Chrome and Firefox (!), but see also Is there a W3C valid way to disable autocomplete in a HTML form?

First represent the epoch of the millisecond time as a date (usually 1/1/1970), then add your millisecond time divided by the number of milliseconds in a day (86400000):

=DATE(1970,1,1)+(A1/86400000)

If your cell is properly formatted, you should see a human-readable date/time.

Strange but it is a two step task:

1. Search what you want
2. In the search tab right click and select replace , or replace all:

Having 2 scripts called test.bat and ping.bat in same folder:

Script test.bat contains one line:

ping google.com

Script ping.bat contains below lines:

@echo off
echo Hello!
pause

Executing "test.bat" the result on CMD will be:

Hello!
Press any key to continue . . .

Why? Because "test.bat" is calling the "ping.bat" ("ping google.com" is interpreted as calling the "ping.bat" script). Same is happening if script "ping.bat" contains "ping google.com". The script will execute himself in a loop.

Easy ways to avoid this:

1. Do not name your script "ping.bat".
2. You can name the script as "ping.bat" but inside the script use "ping.exe google.com" instead of "ping google.com".

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

@Schildmeijer is largely right, however port 7001 is still used when using TLS Encrypted Internode communication

So my complete list would be for current versions of Cassandra:

• 7199 - JMX (was 8080 pre Cassandra 0.8.xx)
• 7000 - Internode communication (not used if TLS enabled)
• 7001 - TLS Internode communication (used if TLS enabled)
• 9160 - Thrift client API
• 9042 - CQL native transport port

Missing driver file.

This error is really common for people just getting started with PDI.

Drivers go in \pentaho\design-tools\data-integration\libext\JDBC for PDI. If you are using other tools in the Pentaho suite, you may need to copy drivers to additional locations for those tools. For reference, here are the appropriate folders for some of the other design tools:

• Aggregation Designer: \pentaho\design-tools\aggregation-designer\drivers
• Metadata Editor: \pentaho\design-tools\metadata-editor\libext\JDBC
• Report Designer: \pentaho\design-tools\report-designer\lib\jdbc
• Schema Workbench: \pentaho\design-tools\schema-workbench\drivers

If this transformation or job will run on another box, such as a test or production server, don't forget to include copying the jar file and restarting PDI or the Data Integration Server in your deployment considerations.

I think the simplest solution, rather than making the body element partially transparent, would be to add an extra div to hold the background, and change the opacity there, instead.

So you would add a div like:

<div id="background"></div>

And move your body element's background CSS to it, as well as some additional positioning properties, like this:

#background {
    position: fixed;
    top: 0;
    left: 0;
    width: 100%;
    height: 100%;
    background-image: url('images/background.jpg');
    background-repeat: no-repeat;
    background-attachment: fixed;
    background-size: 100%;
    opacity: 0.8;
    filter:alpha(opacity=80);
}

Here's an example: http://jsfiddle.net/nbVg4/4/

I think your particular problem isn't how to use Glyphicons but understanding how Bootstrap files work together.

Bootstrap requires a specific file structure to work. I see from your code you have this:

<link href="bootstrap.css" rel="stylesheet" media="screen">

Your Bootstrap.css is being loaded from the same location as your page, this would create a problem if you didn't adjust your file structure.

But first, let me recommend you setup your folder structure like so:

/css      <-- Bootstrap.css here
/fonts    <-- Bootstrap fonts here
/img
/js       <-- Bootstrap JavaScript here
index.html

If you notice, this is also how Bootstrap structures its files in its download ZIP.

You then include your Bootstrap file like so:

<link href="css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="./css/bootstrap.css" rel="stylesheet" media="screen">
or
<link href="/css/bootstrap.css" rel="stylesheet" media="screen">

Depending on your server structure or what you're going for.

The first and second are relative to your file's current directory. The second one is just more explicit by saying "here" (./) first then css folder (/css).

The third is good if you're running a web server, and you can just use relative to root notation as the leading "/" will be always start at the root folder.

So, why do this?

Bootstrap.css has this specific line for Glyphfonts:

@font-face {
    font-family: 'Glyphicons Halflings';
    src: url('../fonts/glyphicons-halflings-regular.eot');
    src: url('../fonts/glyphicons-halflings-regular.eot?#iefix') format('embedded-opentype'), url('../fonts/glyphicons-halflings-regular.woff') format('woff'), url('../fonts/glyphicons-halflings-regular.ttf') format('truetype'), url('../fonts/glyphicons-halflings-regular.svg#glyphicons-halflingsregular') format('svg');
}

What you can see is that that Glyphfonts are loaded by going up one directory ../ and then looking for a folder called /fonts and THEN loading the font file.

The URL address is relative to the location of the CSS file. So, if your CSS file is at the same location like this:

/fonts
Bootstrap.css
index.html

The CSS file is going one level deeper than looking for a /fonts folder.

So, let's say the actual location of these files are:

C:\www\fonts
C:\www\Boostrap.css
C:\www\index.html

The CSS file would technically be looking for a folder at:

C:\fonts

but your folder is actually in:

C:\www\fonts

So see if that helps. You don't have to do anything 'special' to load Bootstrap Glyphicons, except make sure your folder structure is set up appropriately.

When you get that fixed, your HTML should simply be:

<span class="glyphicon glyphicon-comment"></span>

Note, you need both classes. The first class glyphicon sets up the basic styles while glyphicon-comment sets the specific image.

Try wrapping your dates in single quotes, like this:

'15-6-2005'

It should be able to parse the date this way.

ffmpeg -i sample.avi will give you the audio/video format info for your file. Make sure you have the proper libraries configured to parse the input streams. Also, make sure that the file isn't corrupt.

The fix is really simple: just replace YOUR_API_KEY on the last line of your code with your actual API key!

If you don't have one, you can get it for free on the Google Developers Website.

This worked for me:

$ sudo apt-get install php-gd php-mysql

[Offering a somewhat more descriptive answer than the answer provided by @Ajni.]

This can also be achieved using LINQ fluent syntax:

var list = ctn.Items
    .Where(t=> t.DeliverySelection == true && t.Delivery.SentForDelivery == null)
    .OrderBy(t => t.Delivery.SubmissionDate)
    .Take(5);

Note that each method (Where, OrderBy, Take) that appears in this LINQ statement takes a lambda expression as an argument. Also note that the documentation for Enumerable.Take begins with:

Returns a specified number of contiguous elements from the start of a sequence.

Use a generator together with any, which short-circuits on the first True:

if any(ext in url_string for ext in extensionsToCheck):
    print(url_string)

EDIT: I see this answer has been accepted by OP. Though my solution may be "good enough" solution to his particular problem, and is a good general way to check if any strings in a list are found in another string, keep in mind that this is all that this solution does. It does not care WHERE the string is found e.g. in the ending of the string. If this is important, as is often the case with urls, you should look to the answer of @Wladimir Palant, or you risk getting false positives.

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

The lifecycle is controlled by the application/user.

From the standard:

User agents should expire data from the local storage areas only for security reasons or when requested to do so by the user. User agents should always avoid deleting data while a script that could access that data is running.

Note: This may be obsolete for current versions of Amazon Linux 2 since late 2018 (see comments), you can now directly install it via yum install python3.

In Amazon Linux 2, there isn't a python3[4-6] in the default yum repos, instead there's the Amazon Extras Library.

sudo amazon-linux-extras install python3

If you want to set up isolated virtual environments with it; using yum install'd virtualenv tools don't seem to reliably work.

virtualenv --python=python3 my_venv

Calling the venv module/tool is less finicky, and you could double check it's what you want/expect with python3 --version beforehand.

python3 -m venv my_venv

[1, 2, 3, 4, 5]

EDIT To @Danny's comment: my original suggestion does not keep the keys ordered. If you need the keys sorted, try:

>>> from collections import OrderedDict

>>> OrderedDict( (x,1) for x in mylist ).keys()
[3, 2, 1, 4, 5]

which keeps elements in the order by the first occurrence of the element (not extensively tested)

October 2020 update

As was mentioned, you can use xcrun to do a few things:

• xcrun simctl list devices or xcrun simctl list --json to list all simulators
• xcrun simctl delete <device udid> to delete specific device
• xcrun simctl delete unavailable to remove old devices for runtimes that are no longer supported

More things you can do with xcrun (see code snippet)

- `xcrun simctl boot <device udid>` to launch (multiple) simulators
- `xcrun simctl io booted recordVideo — type=mp4 ./test.mp4` to record simulator video
- `xcrun simctl io booted screenshot ./screen.png` to make screenshot of simulator
- `xcrun simctl openurl booted https://google.com` to open URL in simulator
- `xcrun simctl addmedia booted ./test.mp4` to upload photo or video file (for photos app)
- `xcrun simctl get_app_container booted <your apps bundle identifier>` to find the app container (where identifier is like *com.bundle.identifier*)
- `xcrun simctl help` to explore **more** commands

Original Answer

September 2017, Xcode 9

Runtimes

You will find them here:

/Library/Developer/CoreSimulator/Profiles/Runtimes

Devices

To delete devices go here:

~/Library/Developer/CoreSimulator/Devices

Much easier to delete them use Xcode: Xcode->Window->Devices and Simulators

Helping Xcode "forget" about runtimes and prevent from re-installing them - delete .dmg file(s) here:

~/Library/Caches/com.apple.dt.Xcode/Downloads

I hope it will help someone

Here is my solution. I first create random numbers with random.uniform, format them in to string with double precision and then convert them back to float. You can adjust the precision by changing '.2f' to '.3f' etc..

import random
from decimal import Decimal

GndSpeedHigh = float(format(Decimal(random.uniform(5, 25)), '.2f'))
GndSpeedLow = float(format(Decimal(random.uniform(2, GndSpeedHigh)), '.2f'))
GndSpeedMean = float(Decimal(format(GndSpeedHigh + GndSpeedLow) / 2, '.2f')))
print(GndSpeedMean)

You can apply Object.prototype.toString to any object:

var toString = Object.prototype.toString;

console.log(toString.call([]));
//-> [object Array]

console.log(toString.call(/reg/g));
//-> [object RegExp]

console.log(toString.call({}));
//-> [object Object]

This works well in all browsers, with the exception of IE - when calling this on a variable obtained from another window it will just spit out [object Object].

You've got the same basic restriction when running a 32bit process under Win64. Your app runs in a 32 but subsystem which does its best to look like Win32, and this will include the memory restrictions for your process (lower 2GB for you, upper 2GB for the OS)

Following with Oleg answer, if you want to find ALL objects in a List filtered by a property, you could do something like:

//Search into a generic list ALL items with a generic property
public final class SearchTools {
       public static <T> List<T> findByProperty(Collection<T> col, Predicate<T> filter) {
           List<T> filteredList = (List<T>) col.stream().filter(filter).collect(Collectors.toList());
           return filteredList;
     }

//Search in the list "listItems" ALL items of type "Item" with the specific property "iD_item=itemID"
public static final class ItemTools {
         public static List<Item> findByItemID(Collection<Item> listItems, String itemID) {
             return SearchTools.findByProperty(listItems, item -> itemID.equals(item.getiD_Item()));
         }
     }
}

and similarly if you want to filter ALL items in a HashMap with a certain Property

//Search into a MAP ALL items with a given property
public final class SearchTools {
       public static <T> HashMap<String,T> filterByProperty(HashMap<String,T> completeMap, Predicate<? super Map.Entry<String,T>> filter) {
           HashMap<String,T> filteredList = (HashMap<String,T>) completeMap.entrySet().stream()
                                .filter(filter)
                                .collect(Collectors.toMap(map -> map.getKey(), map -> map.getValue()));
           return filteredList;
     }

     //Search into the MAP ALL items with specific properties
public static final class ItemTools {

        public static HashMap<String,Item> filterByParentID(HashMap<String,Item> mapItems, String parentID) {
            return SearchTools.filterByProperty(mapItems, mapItem -> parentID.equals(mapItem.getValue().getiD_Parent()));
        }

        public static HashMap<String,Item> filterBySciName(HashMap<String,Item> mapItems, String sciName) {
            return SearchTools.filterByProperty(mapItems, mapItem -> sciName.equals(mapItem.getValue().getSciName()));
        }
    }

Have a look at CSS and HTML in depth you will figure this out. It just floating the boxes left and right and those boxes need to be inside a same div. http://www.w3schools.com/html/html_layout.asp might be a good resource.

Installing proxyconf will solve this, but behind a proxy you can't install a plugin simply using the command vagrant plugin install, Bundler will raise an error.

set your proxy in your environment if you're using a unix like system

export http_proxy=http://user:password@host:port

or get a more detailed answer here: How to use bundler behind a proxy?

after this set up proxyconf

That you can handle the checked and unchecked events seperately doesn't mean you have to. If you don't want to follow the MVVM pattern you can simply attach the same handler to both events and you have your change signal:

<CheckBox Checked="CheckBoxChanged" Unchecked="CheckBoxChanged"/>

and in Code-behind;

private void CheckBoxChanged(object sender, RoutedEventArgs e)
{
  MessageBox.Show("Eureka, it changed!");
}

Please note that WPF strongly encourages the MVVM pattern utilizing INotifyPropertyChanged and/or DependencyProperties for a reason. This is something that works, not something I would like to encourage as good programming habit.

The first case is telling the web server that you are posting JSON data as in:

{ Name : 'John Smith', Age: 23}

The second option is telling the web server that you will be encoding the parameters in the URL as in:

Name=John+Smith&Age=23

    public String encrypt(String str) {
        try {
            // Encode the string into bytes using utf-8
            byte[] utf8 = str.getBytes("UTF8");

            // Encrypt
            byte[] enc = ecipher.doFinal(utf8);

            // Encode bytes to base64 to get a string
            return new sun.misc.BASE64Encoder().encode(enc);
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }

    public String decrypt(String str) {
        try {
            // Decode base64 to get bytes
            byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);

            // Decrypt
            byte[] utf8 = dcipher.doFinal(dec);

            // Decode using utf-8
            return new String(utf8, "UTF8");
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }
}

Here's an example that uses the class:

try {
    // Generate a temporary key. In practice, you would save this key.
    // See also Encrypting with DES Using a Pass Phrase.
    SecretKey key = KeyGenerator.getInstance("DES").generateKey();

    // Create encrypter/decrypter class
    DesEncrypter encrypter = new DesEncrypter(key);

    // Encrypt
    String encrypted = encrypter.encrypt("Don't tell anybody!");

    // Decrypt
    String decrypted = encrypter.decrypt(encrypted);
} catch (Exception e) {
}

Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way

var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";

for (var key in foo) {
        console.log(key);
}

Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.

EDIT:

In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -

• "Associative Arrays" considered Harmful

from PIL import Image
import os, os.path

imgs = []
path = "/home/tony/pictures"
valid_images = [".jpg",".gif",".png",".tga"]
for f in os.listdir(path):
    ext = os.path.splitext(f)[1]
    if ext.lower() not in valid_images:
        continue
    imgs.append(Image.open(os.path.join(path,f)))
   

If you're doing a LOAD DATA INFILE 'myfile.csv' operation, the easiest way to see if all the lines went in is to check show warnings(); If you load the data into an empty or temporary table, you can also check the number of rows that it has after the insert.

SELECT * FROM 
  MY_TABLE
WHERE 
  <your filters>
ORDER BY PRIMARY_KEY DESC FETCH FIRST ROW ONLY

You could do this but the T generic parameter needs to be declared at the containing class:

public class Foo<T>
{
    public List<T> NewList { get; set; }
}

As stated in this reddit post, after Angular 7, you can simplify things to these 2 steps:

1. Add those three lines to compilerOptions in your tsconfig.json file:

"resolveJsonModule": true,
"esModuleInterop": true,
"allowSyntheticDefaultImports": true

2. Import your json data:

import myData from '../assets/data/my-data.json';

And that's it. You can now use myDatain your components/services.

I know this thread is very old but for those not using SQL Server 2012 or above or cannot use the FORMAT function for any reason then the following works.

Also, a lot of the solutions did not work if the number was less than 1 (e.g. 0.01230000).

Please note that the following does not work with negative numbers.

DECLARE @num decimal(28,14) = 10.012345000
SELECT PARSENAME(@num,2) + REPLACE(RTRIM(LTRIM(REPLACE(@num-PARSENAME(@num,2),'0',' '))),' ','0') 

set @num = 0.0123450000
SELECT PARSENAME(@num,2) + REPLACE(RTRIM(LTRIM(REPLACE(@num-PARSENAME(@num,2),'0',' '))),' ','0') 

Returns 10.012345 and 0.012345 respectively.

For me this was resolved by adding an explicit default constructor

public MyClassName (){}

My assumption you already have settings on your urls.py

from django.urls import path, include 
# and probably something like this 
    urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
]

and on your app you should have something like this blog/urls.py

 from django.urls import path

 from .views import HomePageView, CreateBlogView

 urlpatterns = [
   path('', HomePageView.as_view(), name='home'),
   path('post/', CreateBlogView.as_view(), name='add_blog')
 ]

if it's the case then most likely you haven't activated your environment try the following to activate your environment first pipenv shell if you still get the same error try this methods below

make sure Django is installed?? any another packages? i.e pillow try the following

pipenv install django==2.1.5 pillow==5.4.1

then remember to activate your environment

pipenv shell

after the environment is activated try running

python3 manage.py makemigrations

python3 manage.py migrate

then you will need to run

python3 manage.py runserver

I hope this helps

ephemeral is just another name of root volume when you launch Instance from AMI backed from Amazon EC2 instance store

So Everything will be stored on ephemeral.

if you have launched your instance from AMI backed by EBS volume then your instance does not have ephemeral.

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

If you do not need the serialized text to be human readable, you can use pickle.

import pickle

s = set([1,2,3])

serialized_s = pickle.dumps(s)
print "serialized:"
print serialized_s

deserialized_s = pickle.loads(serialized_s)
print "deserialized:"
print deserialized_s

Result:

serialized:
c__builtin__
set
p0
((lp1
I1
aI2
aI3
atp2
Rp3
.
deserialized:
set([1, 2, 3])

Personally, I would prefer

<IF>
  <TIME from="5pm" to="9pm" />
  <THEN>
    <!-- action -->
  </THEN>
  <ELSE>
    <!-- action -->
  </ELSE>
</IF>

In this way you don't need an id attribute to tie together the IF, THEN, ELSE tags

Use the following selector.

$('#attached_docs [value=123]').remove();

@keyframes rotate {
    100% {
        transform: rotate(1turn);
    }
}

div{
   animation: rotate 4s linear infinite;
}

You can put a meta refresh Tag in the irc_online.php

<meta http-equiv="refresh" content="30">

OR you can use Javascript with setInterval to refresh the src of the Source...

<script>
window.setInterval("reloadIFrame();", 30000);

function reloadIFrame() {
 document.frames["frameNameHere"].location.reload();
}
</script>

Java 8 provides different utility api methods to help us sort the streams better.

If your list is a list of Integers(or Double, Long, String etc.,) then you can simply sort the list with default comparators provided by java.

List<Integer> integerList = Arrays.asList(1, 4, 3, 4, 5);

Creating comparator on fly:

integerList.stream().sorted((i1, i2) -> i1.compareTo(i2)).forEach(System.out::println);

With default comparator provided by java 8 when no argument passed to sorted():

integerList.stream().sorted().forEach(System.out::println); //Natural order

If you want to sort the same list in reverse order:

 integerList.stream().sorted(Comparator.reverseOrder()).forEach(System.out::println); // Reverse Order

If your list is a list of user defined objects, then:

List<Person> personList = Arrays.asList(new Person(1000, "First", 25, 30000),
        new Person(2000, "Second", 30, 45000),
        new Person(3000, "Third", 35, 25000));

Creating comparator on fly:

personList.stream().sorted((p1, p2) -> ((Long)p1.getPersonId()).compareTo(p2.getPersonId()))
        .forEach(person -> System.out.println(person.getName()));

Using Comparator.comparingLong() method(We have comparingDouble(), comparingInt() methods too):

personList.stream().sorted(Comparator.comparingLong(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

Using Comparator.comparing() method(Generic method which compares based on the getter method provided):

personList.stream().sorted(Comparator.comparing(Person::getPersonId)).forEach(person -> System.out.println(person.getName()));

We can do chaining too using thenComparing() method:

personList.stream().sorted(Comparator.comparing(Person::getPersonId).thenComparing(Person::getAge)).forEach(person -> System.out.println(person.getName())); //Sorting by person id and then by age.

Person class

public class Person {
    private long personId;
    private String name;
    private int age;
    private double salary;

    public long getPersonId() {
        return personId;
    }

    public void setPersonId(long personId) {
        this.personId = personId;
    }

    public Person(long personId, String name, int age, double salary) {
        this.personId = personId;
        this.name = name;
        this.age = age;

        this.salary = salary;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

    public double getSalary() {
        return salary;
    }

    public void setSalary(double salary) {
        this.salary = salary;
    }
}

Try this one if you are working with python 2.7:

from __future__ import print_function

Find the process and terminate it. On Windows do a Control+Alt+Delete and then find the "Java(TM) Platform SE Binary" process under the Processes Tab. For example:

On Ubuntu, you can use "ps aux | grep java" to find the process and "kill -9 PID_NUMBER" to kill the process.

OR

If you're using a Spring boot application, go to application.properties and add this:

server.port = 8081

To clear all the webview caches while you signOUT form your APP:

CookieSyncManager.createInstance(this);         
CookieManager cookieManager = CookieManager.getInstance();        
cookieManager.removeAllCookie();

For Lollipop and above:

CookieSyncManager.createInstance(this);         
CookieManager cookieManager = CookieManager.getInstance();        
cookieManager.removeAllCookies(ValueCallback);

For me when i did - dotnet restore still error was occurring.

I went to

1 Tool -> NuGet Package Maneger -> Package Manager settings -> click on "Clear on Nuget Catche(s)"

2 dotnet restore

resolved issues.

If you don't want to use WMI, I can suggest systeminfo.exe. But, there may be a better way to do that.

(systeminfo | Select-String 'Total Physical Memory:').ToString().Split(':')[1].Trim()

A common idiom to change every element of a list looks like this:

for i in range(len(L)):
    item = L[i]
    # ... compute some result based on item ...
    L[i] = result

This can be rewritten using enumerate() as:

for i, item in enumerate(L):
    # ... compute some result based on item ...
    L[i] = result

See enumerate.

My solution to this was to write the script block dynamically with [scriptblock]:Create:

# Or build a complex local script with MARKERS here, and do substitutions
# I was sending install scripts to the remote along with MSI packages
# ...for things like Backup and AV protection etc.

$p1 = "good stuff"; $p2 = "better stuff"; $p3 = "best stuff"; $etc = "!"
$script = [scriptblock]::Create("MyScriptOnRemoteServer.ps1 $p1 $p2 $etc")
#strings get interpolated/expanded while a direct scriptblock does not

# the $parms are now expanded in the script block itself
# ...so just call it:
$result = invoke-command $computer -script $script

Passing arguments was very frustrating, trying various methods, e.g.,
-arguments, $using:p1, etc. and this just worked as desired with no problems.

Since I control the contents and variable expansion of the string which creates the [scriptblock] (or script file) this way, there is no real issue with the "invoke-command" incantation.

(It shouldn't be that hard. :) )

I had a similar issue. I've discovered that MTP is not supported in OSX. I changed it to PTP, I was promoted to approve my laptop and then my device was finally listed (LG G3).

First, let's note that git push "wants" two more arguments and will make them up automatically if you don't supply them. The basic command is therefore git push remote refspec.

The remote part is usually trivial as it's almost always just the word origin. The trickier part is the refspec. Most commonly, people write a branch name here: git push origin master, for instance. This uses your local branch to push to a branch of the same name¹ on the remote, creating it if necessary. But it doesn't have to be just a branch name.

In particular, a refspec has two colon-separated parts. For git push, the part on the left identifies what to push,² and the part on the right identifies the name to give to the remote. The part on the left in this case would be branch_name and the part on the right would be branch_name_test. For instance:

git push origin foo:foo_test

As you are doing the push, you can tell your git push to set your branch's upstream name at the same time, by adding -u to the git push options. Setting the upstream name makes your git save the foo_test (or whatever) name, so that a future git push with no arguments, while you're on the foo branch, can try to push to foo_test on the remote (git also saves the remote, origin in this case, so that you don't have to enter that either).

You need only pass -u once: it basically just runs git branch --set-upstream-to for you. (If you pass -u again later, it re-runs the upstream-setting, changing it as directed; or you can run git branch --set-upstream-to yourself.)

However, if your git is 2.0 or newer, and you have not set any special configuration, you will run into the same kind of thing that had me enter footnote 1 above: push.default will be set to simple, which will refuse to push because the upstream's name differs from your own local name. If you set push.default to upstream, git will stop complaining—but the simplest solution is just to rename your local branch first, so that the local and remote names match. (What settings to set, and/or whether to rename your branch, are up to you.)

¹More precisely, git consults your remote.remote.push setting to derive the upstream half of the refspec. If you haven't set anything here, the default is to use the same name.

²This doesn't have to be a branch name. For instance, you can supply HEAD, or a commit hash, here. If you use something other than a branch name, you may have to spell out the full refs/heads/branch on the right, though (it depends on what names are already on the remote).

Take a look at this:

Publish / Subscribe With jQuery

June 17th, 2008

With a view to writing a jQuery UI integrated with the offline functionality of Google Gears i’ve been toying with some code to poll for network connection status using jQuery.

The Network Detection Object

The basic premise is very simple. We create an instance of a network detection object which will poll a URL at regular intervals. Should these HTTP requests fail we can assume that network connectivity has been lost, or the server is simply unreachable at the current time.

$.networkDetection = function(url,interval){
    var url = url;
    var interval = interval;
    online = false;
    this.StartPolling = function(){
        this.StopPolling();
        this.timer = setInterval(poll, interval);
    };
    this.StopPolling = function(){
        clearInterval(this.timer);
    };
    this.setPollInterval= function(i) {
        interval = i;
    };
    this.getOnlineStatus = function(){
        return online;
    };
    function poll() {
        $.ajax({
            type: "POST",
            url: url,
            dataType: "text",
            error: function(){
                online = false;
                $(document).trigger('status.networkDetection',[false]);
            },
            success: function(){
                online = true;
                $(document).trigger('status.networkDetection',[true]);
            }
        });
    };
};

You can view the demo here. Set your browser to work offline and see what happens…. no, it’s not very exciting.

Trigger and Bind

What is exciting though (or at least what is exciting me) is the method by which the status gets relayed through the application. I’ve stumbled upon a largely un-discussed method of implementing a pub/sub system using jQuery’s trigger and bind methods.

The demo code is more obtuse than it need to be. The network detection object publishes ’status ‘events to the document which actively listens for them and in turn publishes ‘notify’ events to all subscribers (more on those later). The reasoning behind this is that in a real world application there would probably be some more logic controlling when and how the ‘notify’ events are published.

$(document).bind("status.networkDetection", function(e, status){
    // subscribers can be namespaced with multiple classes
    subscribers = $('.subscriber.networkDetection');
    // publish notify.networkDetection even to subscribers
    subscribers.trigger("notify.networkDetection", [status])
    /*
    other logic based on network connectivity could go here
    use google gears offline storage etc
    maybe trigger some other events
    */
});

Because of jQuery’s DOM centric approach events are published to (triggered on) DOM elements. This can be the window or document object for general events or you can generate a jQuery object using a selector. The approach i’ve taken with the demo is to create an almost namespaced approach to defining subscribers.

DOM elements which are to be subscribers are classed simply with “subscriber” and “networkDetection”. We can then publish events only to these elements (of which there is only one in the demo) by triggering a notify event on $(“.subscriber.networkDetection”)

The #notifier div which is part of the .subscriber.networkDetection group of subscribers then has an anonymous function bound to it, effectively acting as a listener.

$('#notifier').bind("notify.networkDetection",function(e, online){
    // the following simply demonstrates
    notifier = $(this);
    if(online){
        if (!notifier.hasClass("online")){
            $(this)
                .addClass("online")
                .removeClass("offline")
                .text("ONLINE");
        }
    }else{
        if (!notifier.hasClass("offline")){
            $(this)
                .addClass("offline")
                .removeClass("online")
                .text("OFFLINE");
        }
    };
});

So, there you go. It’s all pretty verbose and my example isn’t at all exciting. It also doesn’t showcase anything interesting you could do with these methods, but if anyone’s at all interested to dig through the source feel free. All the code is inline in the head of the demo page

I just used getLocaleString() function for my application. It should adapt the timeformat common to the locale, so no +0200 etc. Ofcourse, there will be less possibility for controlling the width of your string then.

var str = (new Date(1400167800)).toLocaleString();

Open SQL Developer. Go to Tools -> Preferences -> Databases -> Advanced Then explicitly set the Tnsnames Directory

My TNSNAMES was set up correctly and I could connect to Toad, SQL*Plus etc. but I needed to do this to get SQL Developer to work. Perhaps it was a Win 7 issue as it was a pain to install too.

Using David's Instance Storage answer initially worked for me (on a m5d.2xlarge) however, after stopping the EC2 instance and turning it back on, I was unable to ssh in to the instance again.

The instance logs reported: "You are in emergency mode. After logging in, type "journalctl -xb" to view system logs, "systemctl reboot" to reboot, "systemctl default" or "exit" to boot into default mode. Press Enter for maintenance"

I instead followed the AWS instructions in this link and everything worked perfectly, including after turning the instance off and on again.

In case, it helps someone:

Use case: i am using a self-signed certificate for my development on localhost.

Error: Caused by: java.security.cert.CertificateException: No name matching localhost found

Solution: When you generate your self-signed certicate, make sure you answer this question like that(See Bruno's answer for the why):

What is your first and last name?
  [Unknown]:  localhost

As a bonus, here are my steps:
1. Generate self-signed certificate:

keytool -genkeypair -alias netty -storetype PKCS12 -keyalg RSA -keysize 2048 -keystore keystore.p12 -validity 4000
Enter keystore password: ***
Re-enter new password: ***
What is your first and last name?
  [Unknown]:  localhost
...

2. Copy the certificate in src/main/resources(if necessary)

3. Update the cacerts
keytool -v -importkeystore -srckeystore keystore.p12 -srcstoretype pkcs12 -destkeystore "%JAVA_HOME%\jre\lib\security\cacerts" -deststoretype jks

4. Update your config(in my case application.properties):

server.port=8443
server.ssl.key-store=classpath:keystore.p12
server.ssl.key-store-password=jumping_monkey
server.ssl.key-store-type=pkcs12
server.ssl.key-alias=netty

try to implement Application_AuthenticateRequest instead of Application_Start.

this method has an instance for HttpContext.Current, unlike Application_Start (which fires very soon in app lifecycle, soon enough to not hold a HttpContext.Current object yet).

hope that helps.

The ist and 2nd answer are good but if anybody is looking for having a script or If you want dynamic i.e (db/username/password in variable) then here:

#!/bin/bash



DB="mydb"
USER="user1"
PASS="pass_bla"

mysql -uroot -prootpassword -e "CREATE DATABASE $DB CHARACTER SET utf8 COLLATE utf8_general_ci";
mysql -uroot -prootpassword -e "CREATE USER $USER@'127.0.0.1' IDENTIFIED BY '$PASS'";
mysql -uroot -prootpassword -e "GRANT SELECT, INSERT, UPDATE ON $DB.* TO '$USER'@'127.0.0.1'";

Here is the formula

create a new rule in conditional formating based on a formula. Use the following formula and apply it to $A:$A

=NOT(ISERROR(MATCH(A1,$B$1:$B$1000,0)))

here is the example sheet to download if you encounter problems

UPDATE
here is @pnuts's suggestion which works perfect as well:

=MATCH(A1,B:B,0)>0

I like to do it like old times. You just use a custom UITextField Class like this one:

//
//  ReadOnlyTextField.swift
//  MediFormulas
//
//  Created by Oscar Rodriguez on 6/21/17.
//  Copyright © 2017 Nica Code. All rights reserved.
//

import UIKit

class ReadOnlyTextField: UITextField {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    override init(frame: CGRect) {
        super.init(frame: frame)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        // Avoid keyboard to show up
        self.inputView = UIView()
    }

    override func canPerformAction(_ action: Selector, withSender sender: Any?) -> Bool {
        // Avoid cut and paste option show up
        if (action == #selector(self.cut(_:))) {
            return false
        } else if (action == #selector(self.paste(_:))) {
            return false
        }

        return super.canPerformAction(action, withSender: sender)
    }

}

<?php
    header("Location: index.html");
?>

Just make sure nothing is actually written to the page prior to this code, or it won't work.

The best thing is probably to create a variable that holds your binaries:

binaries=code1 code2

Then use that in the all-target, to avoid repeating:

all: clean $(binaries)

Now, you can use this with the clean-target, too, and just add some globs to catch object files and stuff:

.PHONY: clean

clean:
    rm -f $(binaries) *.o

Note use of the .PHONY to make clean a pseudo-target. This is a GNU make feature, so if you need to be portable to other make implementations, don't use it.

Use ipcs -a: it gives detailed information of all resources [semaphore, shared-memory etc]

Here is the image of the output:

The folder is part of the URL you set when you create request: "ftp://www.contoso.com/test.htm". If you use "ftp://www.contoso.com/wibble/test.htm" then the file will be uploaded to a folder named wibble.

You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory to make the wibble folder if it doesn't already exist.

$.browser was removed from jQuery starting with version 1.9. It is now available as a plugin. It's generally recommended to avoid browser detection, which is why it was removed.

I think it depends on the situation but anyway you can use the .toString() method as it is very clear to understand.

I normally use the history object for this. It also does not reload the page.

Example:

history.pushState({}, '', 
                `/pagepath/path?query=${this.myQueryParam}`);

The less intuitive solution to this error code seems to be problems with the objects that the synonym is pointing to.

Here is my SQL for finding synonyms that point to erroneous objects.

SELECT S.OWNER as SYN_OWNER, S.SYNONYM_NAME as SYN_NAME,
    S.TABLE_OWNER as OBJ_OWNER, S.TABLE_NAME as OBJ_NAME,
    CASE WHEN O.OWNER is null THEN 'MISSING' ELSE O.STATUS END as OBJ_STATUS
FROM DBA_SYNONYMS S
    LEFT JOIN DBA_OBJECTS O ON S.TABLE_OWNER = O.OWNER AND S.TABLE_NAME = O.OBJECT_NAME
WHERE O.OWNER is null
    OR O.STATUS != 'VALID';

I have tried these hash functions and got the following result. I have about 960^3 entries, each 64 bytes long, 64 chars in different order, hash value 32bit. Codes from here.

One strange things is that almost all the hash functions have 6% collision rate for my data.

If you are on Windows and facing the same problem, have a look at this answer of @Inazense https://stackoverflow.com/a/52869803/4567504.

In Visual studio code I was not able to find “Shell Command: Install 'code' command in PATH command.” so I had to do this manually.

1. Open Environment Variables (System > Advance system settings > Advanced tab > environment variables) on system variables click on Path and click Edit and add new Path named

"C:\Users\Your_Username\AppData\Local\Programs\Microsoft VS Code\bin"

Now you are done! restart command prompt and try again

If you want to go beyond binary evaluation and keep your CSS out of your controller you can implement a simple filter that evaluates the input against a map object:

angular.module('myApp.filters, [])
  .filter('switch', function () { 
      return function (input, map) {
          return map[input] || '';
      }; 
  });

This allows you to write your markup like this:

<div ng-class="muppets.star|switch:{'Kermit':'green', 'Miss Piggy': 'pink', 'Animal': 'loud'}">
    ...
</div>

I am having the same issue here is my scenario

i put empty('') where value is NULL now this '' value does not match with the parent table's id

here is things need to check , all value with presented in parent table otherwise remove data from parent table then try

If you want to do it for your whole WPF application you can do the following: - In the file App.xaml.cs

    protected override void OnStartup(StartupEventArgs e)
    {
        //works for tab into textbox
        EventManager.RegisterClassHandler(typeof(TextBox),
            TextBox.GotFocusEvent,
            new RoutedEventHandler(TextBox_GotFocus));
        //works for click textbox
        EventManager.RegisterClassHandler(typeof(Window),
            Window.GotMouseCaptureEvent,
            new RoutedEventHandler(Window_MouseCapture));

        base.OnStartup(e);
    }
    private void TextBox_GotFocus(object sender, RoutedEventArgs e)
    {
        (sender as TextBox).SelectAll();
    }

    private void Window_MouseCapture(object sender, RoutedEventArgs e)
    {
        var textBox = e.OriginalSource as TextBox;
        if (textBox != null)
             textBox.SelectAll(); 
    }

I found a different solution to this issue. Apparently my IIS 7 did not have 32bit mode enabled in my Application Pool by default.

To enable 32bit mode, open IIS and select your Application Pool. Mine was named "ASP.NET v4.0".
Right click, go to "Advanced Settings" and change the section named: "Enabled 32-bit Applications" to true.

Restart your web server and try again.

I found the fix from this blog reference: http://darrell.mozingo.net/2009/01/17/running-iis-7-in-32-bit-mode/

Additionally, you can change the settings on Visual Studio. In my case, I went to Tools > Options > Projects and Solutions > Web Projects and checked Use the 64 bit version of IIS Express for web sites and projects - This was on VS Pro 2015. Nothing else fixed it but this.

![Clear Cache] Ctrl+Shift+Delete http://i.stack.imgur.com/QpqhJ.jpg Sometimes it’s necessary to do a hard refresh to see the updates take effect. But it’s unlikely that average web users know what a hard refresh is, nor can you expect them to keep refreshing the page until things straighten out. Here’s one way to do it:<link rel="stylesheet" href="style.css?v=1.1">

In general, one doesn't expand out log(a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity:

log(a + b) = log(a * (1 + b/a)) = log a + log(1 + b/a)

(In fact, this identity is often used when implementing log in math libraries).

To define a 3 column grid you could use the customizer or download the source set your less variables and recompile.

To learn more about the grid and the columns / gutter widths, please also read:

• Bootstrap 3 - Set Container Width to 940px Maximum for Desktops?
• Why does Bootstrap 3 force the container width to certain sizes?
• Bootstrap 3 Gutter Size
• Reduce the gutter (default 30px) on smaller devices in Bootstrap3?

In you case with a container of 960px consider the medium grid (see also: http://getbootstrap.com/css/#grid). This grid will have a max container width of 970px. When setting @grid-columns:3; and setting @grid-gutter-width:15px; in variables.less you will get:

15px | 1st column (298.33) | 15px | 2nd column (298.33) |15px | 3th column (298.33) | 15px

int cannot be null. If you are not assigning any value to int default value will be 0. If you want to check for null then make int as Integer in declaration. Then Integer object can be null. So, you can check where it is null or not. Even in javax bean validation you won't be able to get error for @NotNull annotation until the variable is declared as Integer.

Dictionaries themselves do not have ordered items as such, should you want to print them etc to some order, here are some examples:

In Python 2.4 and above:

mydict = {'carl':40,
          'alan':2,
          'bob':1,
          'danny':3}

for key in sorted(mydict):
    print "%s: %s" % (key, mydict[key])

gives:

alan: 2
bob: 1
carl: 40
danny: 3

(Python below 2.4:)

keylist = mydict.keys()
keylist.sort()
for key in keylist:
    print "%s: %s" % (key, mydict[key])

html, body {

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

public static void Main(string[] args)

{

Int[] array = {10, 5, 10, 2, 2, 3, 4, 5, 5, 6, 7, 8, 9, 11, 12, 12};

List<int> doneNumbers = new List<int>();


for (int i = 0; i < array.Length - 1; i++)

{

    if(!doneNumbers.Contains(array[i]))

    {

        int currentNumber = array[i];

        int count = 0;

        for (int j = i; j < array.Length; j++)

        {

            if(currentNumber == array[j])

            {

                count++;

            }

        }

        Console.WriteLine("\t\n " + currentNumber +" "+ " occurs " + " "+count + " "+" times");

        doneNumbers.Add(currentNumber);

        Console.ReadKey();
      }

Introduction

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

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

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

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

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

With an ORM library, it would look like this:

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

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

Pros and Cons

Using ORM saves a lot of time because:

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

Using an ORM library is more flexible because:

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

But ORM can be a pain:

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

How to learn about ORM?

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

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

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

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

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

Here is an example of what I would do. I hope it's what you're looking for.

char_array = c("foo_bar","bar_foo","apple","beer")
a = data.frame("data"=char_array,"data2"=1:4)
a$data = substr(a$data,1,nchar(a$data)-3)

a should now contain:

  data data2
1 foo_ 1
2 bar_ 2
3   ap 3
4    b 4

ConfigurationManager.AppSettings returns the settings defined for the application, not for the specific DLL, you can access them but it's the application settings that will be returned.

If you're using you dll from another application then the ConnectionString shall be in the app.settings of the application.

Let me explain the difference between process and threads first.

A process can have {1..N} number of threads. A small explanation on virtual memory and virtual processor.

Virtual memory

Used as a swap space so that a process thinks that it is sitting on the primary memory for execution.

Virtual processor

The same concept as virtual memory except this is for processor. To a process, it will look it's the only thing that is using the processor.

OS will take care of allocating the virtual memory and virtual processor to a process and performing the swap between processes and doing execution.

All the threads within a process will share the same virtual memory. But, each thread will have their individual virtual processor assigned to them so that they can be executed individually.

Thus saving the memory as well as utilizing the CPU to its potential.

jQuery < 1.8

May I suggest that you use $.ajax() instead of $.post() as it's much more customizable.

If you are calling $.post(), e.g., like this:

$.post( url, data, success, dataType );

You could turn it into its $.ajax() equivalent:

$.ajax({
  type: 'POST',
  url: url,
  data: data,
  success: success,
  dataType: dataType,
  async:false
});

Please note the async:false at the end of the $.ajax() parameter object.

Here you have a full detail of the $.ajax() parameters: jQuery.ajax() – jQuery API Documentation.

jQuery >=1.8 "async:false" deprecation notice

jQuery >=1.8 won't block the UI during the http request, so we have to use a workaround to stop user interaction as long as the request is processed. For example:

• use a plugin e.g. BlockUI;
• manually add an overlay before calling $.ajax(), and then remove it when the AJAX .done() callback is called.

Please have a look at this answer for an example.

I'm using a little helper method:

public static int QueryString(string paramName, int defaultValue)
{
    int value;
    if (!int.TryParse(Request.QueryString[paramName], out value))
        return defaultValue;
    return value;
}

This method allows me to read values from the query string in the following way:

int id = QueryString("id", 0);

There are several ways to try to prevent line breaks, and the phrase “a newer construct” might refer to more than one way—that’s actually the most reasonable interpretation. They probably mostly think of the CSS declaration white-space:nowrap and possibly the no-break space character. The different ways are not equivalent, far from that, both in theory and especially in practice, though in some given case, different ways might produce the same result.

There is probably nothing real to be gained by switching from the HTML attribute to the somewhat clumsier CSS way, and you would surely lose when style sheets are disabled. But even the nowrap attribute does no work in all situations. In general, what works most widely is the nobr markup, which has never made its way to any specifications but is alive and kicking: <td><nobr>...</nobr></td>.

Syntax:

LOAD DATA [LOW_PRIORITY | CONCURRENT] [LOCAL]
INFILE 'file_name' INTO TABLE `tbl_name`
CHARACTER SET [CHARACTER SET charset_name]
FIELDS [{FIELDS | COLUMNS}[TERMINATED BY 'string']] 
[LINES[TERMINATED BY 'string']] 
[IGNORE number {LINES | ROWS}]

See this Example:

LOAD DATA LOCAL INFILE
'E:\\wamp\\tmp\\customer.csv' INTO TABLE `customer`
CHARACTER SET 'utf8'
FIELDS TERMINATED BY ',' ENCLOSED BY '"'
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES;

from the terminal type:-

aws configure

then fill in your keys and region.

after this do next step use any environment. You can have multiple keys depending your account. Can manage multiple enviroment or keys

import boto3
aws_session = boto3.Session(profile_name="prod")
# Create an S3 client
s3 = aws_session.client('s3')

Running the command prompt or Powershell ISE as an administrator fixed this for me.

If you can comment out code and your program still works, then yes, that code was optional.

.strip() with no arguments (or None as the first argument) removes all whitespace at the start and end, including spaces, tabs, newlines and carriage returns. Leaving it in doesn't do any harm, and allows your program to deal with unexpected extra whitespace inserted into the file.

For example, by using .strip(), the following two lines in a file would lead to the same end result:

 foo\tbar \n
foo\tbar\n

I'd say leave it in.

This border is used to show that the element is focused (i.e. you can type in the input or press the button with Enter). You can remove it with outline property, though:

textarea:focus, input:focus{
    outline: none;
}

You may want to add some other way for users to know what element has keyboard focus though for usability.

Chrome will also apply highlighting to other elements such as DIV's used as modals. To prevent the highlight on those and all other elements as well, you can do:

*:focus {
    outline: none;
}

?? Accessibility warning

Please notice that removing outline from input is an accessibility bad practice. Users using screen readers will not be able to see where their pointer is focused at. More info at a11yproject

When you use float without width, there remains some space in that row. To block this space you can use clear:both; in next element.

First use

git pull https://github.com/username/repository master

and then try

git push -u origin master

Your html should be like this:

<button onclick="doSomething" id="id_button">action</button>

And renaming your input-paramter to event like this

function doSomething(event){
    var source = event.target || event.srcElement;
    console.log(source);
}

would solve your problem.

As a side note, I'd suggest taking a look at jQuery and unobtrusive javascript

You can use ListIterator to do the counting:

final List<String> list = Arrays.asList("zero", "one", "two", "three");

for (final ListIterator<String> it = list.listIterator(); it.hasNext();) {
    final String s = it.next();
    System.out.println(it.previousIndex() + ": " + s);
}

You're mixing different format functions.

The old-style % formatting uses % codes for formatting:

'It will cost $%d dollars.' % 95

The new-style {} formatting uses {} codes and the .format method

'It will cost ${0} dollars.'.format(95)

Note that with old-style formatting, you have to specify multiple arguments using a tuple:

'%d days and %d nights' % (40, 40)

In your case, since you're using {} format specifiers, use .format:

"'{0}' is longer than '{1}'".format(name1, name2)

Incredibly late but inspired by Homan's brilliantly simple answer, allow me to post a more general solution (general in the sense that Homan's solution crashes on arrays of points with less than 3 vertices):

function smooth(ctx, points)
{
    if(points == undefined || points.length == 0)
    {
        return true;
    }
    if(points.length == 1)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[0].x, points[0].y);
        return true;
    }
    if(points.length == 2)
    {
        ctx.moveTo(points[0].x, points[0].y);
        ctx.lineTo(points[1].x, points[1].y);

Yes, this is related to new updates in safari that are breaking your layout now if you use overflow: hidden to take care of clearing divs.

Another consideration, if a field is required or has a limited range, perform the check in the constructor:

public Book(String title)
{
    if (title==null)
        throw new IllegalArgumentException("title can't be null");
    this.title = title;
}

@eeezyy's answer didn't work for me, although I'm using Spring Boot (2.0.4) and it may differ, but a variation here in 2018 works thus:

@Autowired
private HttpServletRequest request;

DELETE TB1, TB2
    FROM customer_details
        LEFT JOIN customer_booking on TB1.cust_id = TB2.fk_cust_id
    WHERE TB1.cust_id = $id

This worked for me.

First of all give the view controller in your storyboard a Storyboard ID inside the identity inspector. Then use the following example code (ensuring the class, storyboard name and story board ID match those that you are using):

let viewController:
UIViewController = UIStoryboard(
    name: "Main", bundle: nil
).instantiateViewControllerWithIdentifier("ViewController") as UIViewController
// .instantiatViewControllerWithIdentifier() returns AnyObject!
// this must be downcast to utilize it

self.presentViewController(viewController, animated: false, completion: nil)

For more details see http://sketchytech.blogspot.com/2012/11/instantiate-view-controller-using.html best wishes

use this, it realy works:

data.addColumn no of your key, you can add more columns or remove

<?php
$con=mysql_connect("localhost","USername","Password") or die("Failed to connect with database!!!!");
mysql_select_db("Database Name", $con); 
// The Chart table contain two fields: Weekly_task and percentage
//this example will display a pie chart.if u need other charts such as Bar chart, u will need to change little bit to make work with bar chart and others charts
$sth = mysql_query("SELECT * FROM chart");

while($r = mysql_fetch_assoc($sth)) {
$arr2=array_keys($r);
$arr1=array_values($r);

}

for($i=0;$i<count($arr1);$i++)
{
    $chart_array[$i]=array((string)$arr2[$i],intval($arr1[$i]));
}
echo "<pre>";
$data=json_encode($chart_array);

I saw the answers here and although helpful, they weren't exactly what I wanted since I had to alter a lot of my code.

What worked out for me, was doing something like this:

function isSession(selector) {
    //line added for the var that will have the result
    var result = false;
    $.ajax({
        type: "POST",
        url: '/order.html',
        data: ({ issession : 1, selector: selector }),
        dataType: "html",
        //line added to get ajax response in sync
        async: false,
        success: function(data) {
            //line added to save ajax response in var result
            result = data;
        },
        error: function() {
            alert('Error occured');
        }
    });
    //line added to return ajax response
    return result;
}

I know this has already been answered... but I wanted to give a more complete example.

In my example, the ListActivity that will display our custom ListView is called OptionsActivity, because in my project this Activity is going to display the different options my user can set to control my app. There are two list item types, one list item type just has a TextView and the second list item type just has a Button. You can put any widgets you like inside each list item type, but I kept this example simple.

The getItemView() method checks to see which list items should be type 1 or type 2. According to my static ints I defined up top, the first 5 list items will be list item type 1, and the last 5 list items will be list item type 2. So if you compile and run this, you will have a ListView that has five items that just contain a Button, and then five items that just contain a TextView.

Below is the Activity code, the activity xml file, and an xml file for each list item type.

OptionsActivity.java:

public class OptionsActivity extends ListActivity {

    private static final int LIST_ITEM_TYPE_1 = 0;
    private static final int LIST_ITEM_TYPE_2 = 1;
    private static final int LIST_ITEM_TYPE_COUNT = 2;

    private static final int LIST_ITEM_COUNT = 10;
    // The first five list items will be list item type 1 
    // and the last five will be list item type 2
    private static final int LIST_ITEM_TYPE_1_COUNT = 5;

    private MyCustomAdapter mAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mAdapter = new MyCustomAdapter();
        for (int i = 0; i < LIST_ITEM_COUNT; i++) {
          if (i < LIST_ITEM_TYPE_1_COUNT)
            mAdapter.addItem("item type 1");
          else
            mAdapter.addItem("item type 2");
        }
        setListAdapter(mAdapter);
    }

    private class MyCustomAdapter extends BaseAdapter {

        private ArrayList<String> mData = new ArrayList<String>();
        private LayoutInflater mInflater;

        public MyCustomAdapter() {
            mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

        public void addItem(final String item) {
            mData.add(item);
            notifyDataSetChanged();
        }

        @Override
        public int getItemViewType(int position) {
          if(position < LIST_ITEM_TYPE_1_COUNT)
              return LIST_ITEM_TYPE_1;
          else
              return LIST_ITEM_TYPE_2;
        }

        @Override
        public int getViewTypeCount() {
            return LIST_ITEM_TYPE_COUNT;
        }

        @Override
        public int getCount() {
            return mData.size();
        }

        @Override
        public String getItem(int position) {
            return mData.get(position);
        }

            ViewHolder holder = null;
            int type = getItemViewType(position);
            if (convertView == null) {
                holder = new ViewHolder();
                switch(type) {
                    case LIST_ITEM_TYPE_1:
                        convertView = mInflater.inflate(R.layout.list_item_type1, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type1_text_view);
                        break;
                    case LIST_ITEM_TYPE_2:
                        convertView = mInflater.inflate(R.layout.list_item_type2, null);
                        holder.textView = (TextView)convertView.findViewById(R.id.list_item_type2_button);

Yes you can - first capture the event using onmouseover, then set the class name using Element.className.

If you like to add or remove classes - use the more convenient Element.classList method.

.active {
  background: red;
}

<div onmouseover=className="active">
  Hover this!
</div>

I was wondering nobody suggested to create own extension method more readable name for OP's case.

    }

    return source.Any() == false;

Use Joda Time Library. It is very easy to handle date, time, calender and locale with it and it will be integrated to java in version 8.

DateTime#minusMonths method would help you get previous month.

DateTime month = new DateTime().minusMonths (1); 

You'll need to consider this in context of the application. In general, you should design an application, not a database (the database simply being part of the application).

Consider how your application should respond to various cases.

The default action is to restrict (i.e. not permit) the operation, which is normally what you want as it prevents stupid programming errors. However, on DELETE CASCADE can also be useful. It really depends on your application and how you intend to delete particular objects.

Personally, I'd use InnoDB because it doesn't trash your data (c.f. MyISAM, which does), rather than because it has FK constraints.

Just to keep flogging this particular dead horse- we've had good use of numeric error codes when errors are shown to end-customers, since they frequently forget or misread the actual error message but may sometimes retain and report a numeric value that can give you a clue to what actually happened.

Here is the jsFiddle

#backdrop{
    border: 2px solid red;
    width: 400px;
    height: 200px;
    position: absolute;
}

#curtain {
    border: 1px solid blue;
    width: 400px;
    height: 200px;
    position: absolute;
}

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

or

ul.yourlist li { display:inline; }

You can't alter the existing columns for identity.

You have 2 options,

Create a new table with identity & drop the existing table

Create a new column with identity & drop the existing column

Approach 1. (New table) Here you can retain the existing data values on the newly created identity column.

CREATE TABLE dbo.Tmp_Names
    (
      Id int NOT NULL
             IDENTITY(1, 1),
      Name varchar(50) NULL
    )
ON  [PRIMARY]
go

SET IDENTITY_INSERT dbo.Tmp_Names ON
go

IF EXISTS ( SELECT  *
            FROM    dbo.Names ) 
    INSERT  INTO dbo.Tmp_Names ( Id, Name )
            SELECT  Id,
                    Name
            FROM    dbo.Names TABLOCKX
go

SET IDENTITY_INSERT dbo.Tmp_Names OFF
go

DROP TABLE dbo.Names
go

Exec sp_rename 'Tmp_Names', 'Names'

Approach 2 (New column) You can’t retain the existing data values on the newly created identity column, The identity column will hold the sequence of number.

Alter Table Names
Add Id_new Int Identity(1, 1)
Go

Alter Table Names Drop Column ID
Go

Exec sp_rename 'Names.Id_new', 'ID', 'Column'

The traditional way to flag a method so that it will appear in Interface Builder, and you can drag a connection to it, has been to make the method return type IBAction. However, if you make your method void, instead (IBAction is #define'd to be void), and provide an (id) argument, the method is still visible. This provides extra flexibility, al

All 3 of these are visible from Interface Builder:

-(void) someMethod1:(id) sender; 
-(IBAction) someMethod2; 
-(IBAction) someMethod3:(id) sender;

See Apple's Interface Builder User Guide for details, particularly the section entitled Xcode Integration.

The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:

argument_list        ::=  positional_arguments ["," starred_and_keywords]
                            ["," keywords_arguments]
                          | starred_and_keywords ["," keywords_arguments]
                          | keywords_arguments

Specifically, a keyword argument looks like this: tag='insider trading!' while a positional argument looks like this: ..., exchange, .... The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.

Also, when an argument has a default value, such as price=None, that means you don't have to provide it. If you don't provide it, it will use the default value instead.

To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity)

# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)

# Some positional, some keyword (all keywords at end):

order_id = kite.order_place(self, exchange, tradingsymbol,
    transaction_type, quantity, tag='insider trading!')

You cannot use width: 100px, because the display is table-cell. You can however use Max-width: 100px. then your box will never get bigger than 100px. but you need to add overflow:hidden to make sure the contect don't bleed to other cells. you can also add white-space: nowrap if you wish to keep the height from increasing.

onCreate()

1. When we create DataBase at a first time (i.e Database is not exists) onCreate() create database with version which is passed in SQLiteOpenHelper(Context context, String name, SQLiteDatabase.CursorFactory factory, int version)

2. onCreate() method is creating the tables you’ve defined and executing any other code you’ve written. However, this method will only be called if the SQLite file is missing in your app’s data directory (/data/data/your.apps.classpath/databases).

3. This method will not be called if you’ve changed your code and relaunched in the emulator. If you want onCreate() to run you need to use adb to delete the SQLite database file.

onUpgrade()

1. SQLiteOpenHelper should call the super constructor.
2. The onUpgrade() method will only be called when the version integer is larger than the current version running in the app.
3. If you want the onUpgrade() method to be called, you need to increment the version number in your code.

    ClientValidationFunction="CheckBoxRequired_ClientValidate">You must select this box to proceed.</asp:CustomValidator>

and finally, in your postback - whether from a button or whatever...

if (Page.IsValid)
{
    // your code here...
}

Here is another solution considering all columns (more compact way of J.J's answer);

ar=np.array([[0, 0, 0, 1],
             [1, 0, 1, 0],
             [0, 1, 0, 0],
             [1, 0, 0, 1],
             [0, 0, 1, 0],
             [1, 1, 0, 0]])

Sort with lexsort,

ar[np.lexsort(([ar[:, i] for i in range(ar.shape[1]-1, -1, -1)]))]

Output:

array([[0, 0, 0, 1],
       [0, 0, 1, 0],
       [0, 1, 0, 0],
       [1, 0, 0, 1],
       [1, 0, 1, 0],
       [1, 1, 0, 0]])

The need for pointers in C language is described here

The basic idea is that many limitations in the language (like using arrays, strings and modifying multiple variables in functions) could be removed by manipulating with the memory location of the data. To overcome these limitations, pointers were introduced in C.

Further, it is also seen that using pointers, you can run your code faster and save memory in cases where you are passing big data types (like a structure with many fields) to a function. Making a copy of such data types before passing would take time and would consume memory. This is another reason why programmers prefer pointers for big data types.

I need 50 rep to post a comment against the Signature Option I found most helpful, however I had an issue with images not showing correctly so I had to find a work around. This is my solution:

Using @Morris Maynard's answer as a base https://stackoverflow.com/a/18455148/2337102 I then had to go through the following:

Notes:
Back up your .htm file before starting, copy & paste to a secondary folder

1. You will be working with both the SignatureName.htm and the SignatureName_files Folder

2. You do not need HTML experience, the files will open in an editing program such as Notepad or Notepad++ or your specified HTML Program

3. Navigate to your Signature File location (standard should be C:\Users\"username"\AppData\Roaming\Microsoft\Signatures)

4. Open the SignatureName.htm file in a text/htm editor (right click on the file, "Edit with Program")

5. Use Ctrl+F and enter .png; .jpg or if you don't know your image type, use image001 You will see something like: src="signaturename_files/image001.png"

6. You need to change that to the whole address of the image location C:\Users\YourName\AppData\Roaming\Microsoft\Signatures\SignatureNameFolder_files\image001
   or
   src="E:\location\Signatures\SignatureNameFolder_files\image001.png"

7. Save your file (overwrite it, you had of course backed up the original)

8. Return to Outlook and Open New Mail Item, add your signature. I received a warning that the files had been changed, I clicked ok, I needed to do this twice, then once in the "Edit Signatures Menu".

   Some of the files in this webpage aren't in the expected location. Do you want to download them anyway? If you're sure the Web page is from a trusted source, click Yes."

9. Run your Macro event, the images should now be showing.

If website server is listening to a different port, then yes, simply use http://address:port/

If server is not listening to a different port, then obviously you cannot.

If you just want to pass a std::string to a function that needs const char* you can use

std::string str;
const char * c = str.c_str();

If you want to get a writable copy, like char *, you can do that with this:

std::string str;
char * writable = new char[str.size() + 1];
std::copy(str.begin(), str.end(), writable);
writable[str.size()] = '\0'; // don't forget the terminating 0

// don't forget to free the string after finished using it
delete[] writable;

Edit: Notice that the above is not exception safe. If anything between the new call and the delete call throws, you will leak memory, as nothing will call delete for you automatically. There are two immediate ways to solve this.

boost::scoped_array

boost::scoped_array will delete the memory for you upon going out of scope:

std::string str;
boost::scoped_array<char> writable(new char[str.size() + 1]);
std::copy(str.begin(), str.end(), writable.get());
writable[str.size()] = '\0'; // don't forget the terminating 0

// get the char* using writable.get()

// memory is automatically freed if the smart pointer goes 
// out of scope

std::vector

This is the standard way (does not require any external library). You use std::vector, which completely manages the memory for you.

std::string str;
std::vector<char> writable(str.begin(), str.end());
writable.push_back('\0');

// get the char* using &writable[0] or &*writable.begin()

Most popular C# Data Structures and Collections

• Array
• ArrayList
• List
• LinkedList
• Dictionary
• HashSet
• Stack
• Queue
• SortedList

C#.NET has a lot of different data structures, for example, one of the most common ones is an Array. However C# comes with many more basic data structures. Choosing the correct data structure to use is part of writing a well structured and efficient program.

In this article I will go over the built-in C# data structures, including the new ones introduces in C#.NET 3.5. Note that many of these data structures apply for other programming languages.

Array

The perhaps simplest and most common data structure is the array. A C# array is basically a list of objects. Its defining traits are that all the objects are the same type (in most cases) and there is a specific number of them. The nature of an array allows for very fast access to elements based on their position within the list (otherwise known as the index). A C# array is defined like this:

[object type][] myArray = new [object type][number of elements]

Some examples:

 int[] myIntArray = new int[5];
 int[] myIntArray2 = { 0, 1, 2, 3, 4 };

As you can see from the example above, an array can be intialized with no elements or from a set of existing values. Inserting values into an array is simple as long as they fit. The operation becomes costly when there are more elements than the size of the array, at which point the array needs to be expanded. This takes longer because all the existing elements must be copied over to the new, bigger array.

ArrayList

The C# data structure, ArrayList, is a dynamic array. What that means is an ArrayList can have any amount of objects and of any type. This data structure was designed to simplify the processes of adding new elements into an array. Under the hood, an ArrayList is an array whose size is doubled every time it runs out of space. Doubling the size of the internal array is a very effective strategy that reduces the amount of element-copying in the long run. We won't get into the proof of that here. The data structure is very simple to use:

    ArrayList myArrayList = new ArrayList();
    myArrayList.Add(56);
    myArrayList.Add("String");
    myArrayList.Add(new Form());

The downside to the ArrayList data structure is one must cast the retrived values back into their original type:

int arrayListValue = (int)myArrayList[0]

this did the trick for me.

<div class="CenterImage">
         <asp:Image ID="BrandImage" runat="server" />
</div>

'Note: do not have a css class assocaited to 'BrandImage' in this case

CSS:

.CenterImage {
    position:absolute; 
    width:100%; 
    height:100%
}

.CenterImage img {
    margin: 0 auto;
    display: block;
}
