find this line in php.ini :

;extension=soap

then remove the semicolon ; and restart Apache server

try like this

= IIF( MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ) ) = -1, "",  FormatNumber(  MAX( iif( IsNothing(Fields!.Reading.Value ), -1, Fields!.Reading.Value ), "CellReading_Reading"),3)) )

• A leading slash tells the browser to start at the root directory.
• If you don't have the leading slash, you're referencing from the current directory.
• If you add two dots before the leading slash, it means you're referencing the parent of the current directory.

Take the following folder structure

notice:

• the ROOT checkmark is green,
• the second checkmark is orange,
• the third checkmark is purple,
• the forth checkmark is yellow

Now in the index.html.en file you'll want to put the following markup

<p>
    <span>src="check_mark.png"</span>
    <img src="check_mark.png" />
    <span>I'm purple because I'm referenced from this current directory</span>
</p>

<p>
    <span>src="/check_mark.png"</span>
    <img src="/check_mark.png" />
    <span>I'm green because I'm referenced from the ROOT directory</span>
</p>

<p>
    <span>src="subfolder/check_mark.png"</span>
    <img src="subfolder/check_mark.png" />
    <span>I'm yellow because I'm referenced from the child of this current directory</span>
</p>

<p>
    <span>src="/subfolder/check_mark.png"</span>
    <img src="/subfolder/check_mark.png" />
    <span>I'm orange because I'm referenced from the child of the ROOT directory</span>
</p>

<p>
    <span>src="../subfolder/check_mark.png"</span>
    <img src="../subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced from the parent of this current directory</span>
</p>

<p>
    <span>src="subfolder/subfolder/check_mark.png"</span>
    <img src="subfolder/subfolder/check_mark.png" />
    <span>I'm [broken] because there is no subfolder two children down from this current directory</span>
</p>

<p>
    <span>src="/subfolder/subfolder/check_mark.png"</span>
    <img src="/subfolder/subfolder/check_mark.png" />
    <span>I'm purple because I'm referenced two children down from the ROOT directory</span>
</p>

Now if you load up the index.html.en file located in the second subfolder
http://example.com/subfolder/subfolder/

This will be your output

You can also try this. Credits to the original author who has since removed the script

You have to specify 0 (meaning false) or 1 (meaning true) as the default. Here is an example:

create table mytable (
     mybool boolean not null default 0
);

FYI: boolean is an alias for tinyint(1).

Here is the proof:

mysql> create table mytable (
    ->          mybool boolean not null default 0
    ->     );
Query OK, 0 rows affected (0.35 sec)

mysql> insert into mytable () values ();
Query OK, 1 row affected (0.00 sec)

mysql> select * from mytable;
+--------+
| mybool |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

FYI: My test was done on the following version of MySQL:

mysql> select version();
+----------------+
| version()      |
+----------------+
| 5.0.18-max-log |
+----------------+
1 row in set (0.00 sec)

I was looking for the TOTAL size of the column and hit this article, my solution is based off of MarcE's.

SELECT sum(DATALENGTH(your_field)) AS FIELDSIZE FROM your_table

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myEnumerable.ToList();

When a site is developed using php and it's utter crap, is it:

a) PHPs fault

b) Programmers fault

The recommendation is was to start their name with "X-". E.g. X-Forwarded-For, X-Requested-With. This is also mentioned in a.o. section 5 of RFC 2047.

Update 1: On June 2011, the first IETF draft was posted to deprecate the recommendation of using the "X-" prefix for non-standard headers. The reason is that when non-standard headers prefixed with "X-" become standard, removing the "X-" prefix breaks backwards compatibility, forcing application protocols to support both names (E.g, x-gzip & gzip are now equivalent). So, the official recommendation is to just name them sensibly without the "X-" prefix.

Update 2: On June 2012, the deprecation of recommendation to use the "X-" prefix has become official as RFC 6648. Below are cites of relevance:

3. Recommendations for Creators of New Parameters

...

3. SHOULD NOT prefix their parameter names with "X-" or similar constructs.

4. Recommendations for Protocol Designers

...

4. SHOULD NOT prohibit parameters with an "X-" prefix or similar constructs from being registered.

5. MUST NOT stipulate that a parameter with an "X-" prefix or similar constructs needs to be understood as unstandardized.

6. MUST NOT stipulate that a parameter without an "X-" prefix or similar constructs needs to be understood as standardized.

Note that "SHOULD NOT" ("discouraged") is not the same as "MUST NOT" ("forbidden"), see also RFC 2119 for another spec on those keywords. In other words, you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard.

Summary:

• the official recommendation is to just name them sensibly without the "X-" prefix
• you can keep using "X-" prefixed headers, but it's not officially recommended anymore and you may definitely not document them as if they are public standard

On some computers, I've found that the "2.0" version of MSCOMCTL.OCX has been added to the ActiveX KillBits list, and thus the control won't be allowed to load or run--even in design view. Updating to the "2.1" version will resolve this, and is the recommended solution.

In critical cases, where you have to run a program "now", or you don't have access to source code, or the control is used 400 times in a large modular project, you can use a "big hammer" method and update the registry to re-enable the control:

**
WARNING: Editing the Windows Registry in the wrong way can mess up your computer big time. If you're not sure what you're doing, please leave it alone, or get some schooling before you proceed.
**

The clear the KillBit:

1. Run Registry Editor (regedit.exe or regedt32.exe)
2. In the left-hand panel, navigate to key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility{BDD1F04B-858B-11D1-B16A-00C0F0283628}
3. In the right-hand panel, double-click on “Compatibility Flags”, change the value from Hex 0x400 (Decimal 1024) to 0, then click OK.
4. Launch the application that uses the "2.0" version of MSCOMCTL.OCX; it should run as designed.

The ActiveX KillBits list is intended to give Microsoft the means to disable controls that are deemed to be a security risk, and they've designed the mechanism such that the ActiveX KillBits list will be re-applied to the system at seemingly random times, in addition to when an Update is installed, so you'll need to plan for re-applying the registry change. Making a registry merge file works pretty well, but it's not something you want to do everytime the app runs, because it's not a quiet process (there are ways to do this quietly using Windows Scripting, but you'll have to learn that on your own). The KillBit is checked only when the control is requested by an application, so you're safe from resets once the application launches and loads the control.

You can do it like this:

function fillArray(value, len) {
  if (len == 0) return [];
  var a = [value];
  while (a.length * 2 <= len) a = a.concat(a);
  if (a.length < len) a = a.concat(a.slice(0, len - a.length));
  return a;
}

It doubles the array in each iteration, so it can create a really large array with few iterations.

Note: You can also improve your function a lot by using push instead of concat, as concat will create a new array each iteration. Like this (shown just as an example of how you can work with arrays):

function fillArray(value, len) {
  var arr = [];
  for (var i = 0; i < len; i++) {
    arr.push(value);
  }
  return arr;
}

Whitespace just means characters which are used for spacing, and have an "empty" representation. In the context of python, it means tabs and spaces (it probably also includes exotic unicode spaces, but don't use them). The definitive reference is here: http://docs.python.org/2/reference/lexical_analysis.html#indentation

I'm not sure exactly how to use it.

Put it at the front of the line you want to indent. If you mix spaces and tabs, you'll likely see funky results, so stick with one or the other. (The python community usually follows PEP8 style, which prescribes indentation of four spaces).

You need to create a new indent level after each colon:

for x in range(0, 50):
    print x
    print 2*x

print x

In this code, the first two print statements are "inside" the body of the for statement because they are indented more than the line containing the for. The third print is outside because it is indented less than the previous (nonblank) line.

If you don't indent/unindent consistently, you will get indentation errors. In addition, all compound statements (i.e. those with a colon) can have the body supplied on the same line, so no indentation is required, but the body must be composed of a single statement.

Finally, certain statements, like lambda feature a colon, but cannot have a multiline block as the body.

For those trying to get everything after the first occurance:

Something like "Nic K Cage" to "K Cage".

You can use slice to get everything from a certain character. In this case from the first space:

const delim = " "
const name = "Nic K Cage"

const end = name.split(delim).slice(1).join(delim) // prints: "K Cage"

Or if OP's string had two hyphens:

const text = "sometext-20202-03"
// Option 1
const op1 = text.slice(text.indexOf('-')).slice(1) // prints: 20202-03
// Option 2
const op2 = text.split('-').slice(1).join("-")     // prints: 20202-03

If you treat the content as text, not HTML, then DOM operations should cause the data to be properly encoded. Here's how you'd do it in jQuery:

$('#container').text(xmlString);

Here's how you'd do it with standard DOM methods:

document.getElementById('container')
        .appendChild(document.createTextNode(xmlString));

If you're placing the XML inside of HTML through server-side scripting, there are bound to be encoding functions to allow you to do that (if you add what your server-side technology is, we can give you specific examples of how you'd do it).

To generate jar file in eclipse right click on the project for which you want to generate, Select Export>Java>Runnable Jar File,

Its create jar which includes all the dependencies from Pom.xml, But please make sure license issue if you are using third-party dependency for your application.

:last-child is really the only way to do it without modifying the HTML - but assuming you can do that, the main option is just to give it a class="last-item", then do:

li.last-item { /* ... */ }

Obviously, you can automate this in the dynamic page generation language of your choice. Also, there is a lastChild JavaScript property in the W3C DOM.

Here's an example of doing what you want in Prototype:

$$("ul").each(function(x) { $(x.lastChild).addClassName("last-item"); });

Or even more simply:

$$("ul li:last-child").each(function(x) { x.addClassName("last-item"); });

In jQuery, you can write it even more compactly:

$("ul li:last-child").addClass("last-item");

Also note that this should work without using the actual last-child CSS selector - rather, a JavaScript implementation of it is used - so it should be less buggy and more reliable across browsers.

DO NOT USE OPENSSL DEFAULT KEY DERIVATION.

Currently the accepted answer makes use of it and it's no longer recommended and secure.

It is very feasible for an attacker to simply brute force the key.

https://www.ietf.org/rfc/rfc2898.txt

PBKDF1 applies a hash function, which shall be MD2 [6], MD5 [19] or SHA-1 [18], to derive keys. The length of the derived key is bounded by the length of the hash function output, which is 16 octets for MD2 and MD5 and 20 octets for SHA-1. PBKDF1 is compatible with the key derivation process in PKCS #5 v1.5. PBKDF1 is recommended only for compatibility with existing applications since the keys it produces may not be large enough for some applications.

PBKDF2 applies a pseudorandom function (see Appendix B.1 for an example) to derive keys. The length of the derived key is essentially unbounded. (However, the maximum effective search space for the derived key may be limited by the structure of the underlying pseudorandom function. See Appendix B.1 for further discussion.) PBKDF2 is recommended for new applications.

Do this:

openssl enc -aes-256-cbc -pbkdf2 -iter 20000 -in hello -out hello.enc -k meow

openssl enc -d -aes-256-cbc -pbkdf2 -iter 20000 -in hello.enc -out hello.out

Note: Iterations in decryption have to be the same as iterations in encryption.

Iterations have to be a minimum of 10000. Here is a good answer on the number of iterations: https://security.stackexchange.com/a/3993

Also... we've got enough people here recommending GPG. Read the damn question.

Update: In an effort to answer my own question, here is what I've been able to uncover so far. If anyone else out there has something, I'd still be interested to find out more.

I don't use Retrofit and for OkHttp here is the only solution for self-signed certificate that worked for me:

1. Get a certificate from our site like in Gowtham's question and put it into res/raw dir of the project:

   echo -n | openssl s_client -connect elkews.com:443 | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ./res/raw/elkews_cert.crt
   

2. Use Paulo answer to set ssl factory (nowadays using OkHttpClient.Builder()) but without RestAdapter creation.

3. Then add the following solution to fix: SSLPeerUnverifiedException: Hostname not verified

So the end of Paulo's code (after sslContext initialization) that is working for me looks like the following:

...
OkHttpClient.Builder builder = new OkHttpClient.Builder().sslSocketFactory(sslContext.getSocketFactory());
builder.hostnameVerifier(new HostnameVerifier() {
  @Override
  public boolean verify(String hostname, SSLSession session) {
    return "secure.elkews.com".equalsIgnoreCase(hostname);
});
OkHttpClient okHttpClient = builder.build();

I use following code to get Android id.

String android_id = Secure.getString(this.getContentResolver(),
            Secure.ANDROID_ID);

Log.d("Android","Android ID : "+android_id);

Just adding to the correct answer you can set the timeout with the arrow function like this:

it('Some test', () => {

}).timeout(5000)

When reading to and from your CSV file include the argument index=False so for example:

 df.to_csv(filename, index=False)

and to read from the csv

df.read_csv(filename, index=False)  

This should prevent the issue so you don't need to fix it later.

jQuery plugin scrollintoview() increases usability

Instead of default DOM implementation you can use a plugin that animates movement and doesn't have any unwanted effects. Here's the simplest way of using it with defaults:

$("yourTargetLiSelector").scrollintoview();

Anyway head over to this blog post where you can read all the details and will eventually get you to GitHub source codeof the plugin.

This plugin automatically searches for the closest scrollable ancestor element and scrolls it so that selected element is inside its visible view port. If the element is already in the view port it doesn't do anything of course.

Here's something you can do with AlertBuilder to make the title disappear:

TextView title = new TextView(this);
title.setVisibility(View.GONE);
builder.setCustomTitle(title);

You can use ffprobe to get frame number with the following commands

1. first method

ffprobe.exe -i video_name -print_format json -loglevel fatal -show_streams -count_frames -select_streams v

which tell to print data in json format

select_streams v will tell ffprobe to just give us video stream data and if you remove it, it will give you audio information as well

and the output will be like

            }
        }
    ]
}

2. you can use

ffprobe -v error -show_format -show_streams video_name

which will give you stream data, if you want selected information like frame rate, use the following command

ffprobe -v error -select_streams v:0 -show_entries stream=avg_frame_rate -of default=noprint_wrappers=1:nokey=1 video_name

which give a number base on your video information, the problem is when you use this method, its possible you get a N/A as output.

Trigger hardware accelerated rendering for the problematic element. I would advice to not do this on *, body or html tags for performance.

.problem{
  -webkit-transform:translate3d(0,0,0);
}

To check from the command-line, in one single command, but include major, minor, micro version, releaselevel and serial, then invoke the same Python interpreter (i.e. same path) as you're using for your script:

> path/to/your/python -c "import sys; print('{}.{}.{}-{}-{}'.format(*sys.version_info))"

3.7.6-final-0

Note: .format() instead of f-strings or '.'.join() allows you to use arbitrary formatting and separator chars, e.g. to make this a greppable one-word string. I put this inside a bash utility script that reports all important versions: python, numpy, pandas, sklearn, MacOS, xcode, clang, brew, conda, anaconda, gcc/g++ etc. Useful for logging, replicability, troubleshootingm bug-reporting etc.

You can access the form over the event:

e.target.reset();

Using this simple method

WifiManager wm = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
            String WLANMAC = wm.getConnectionInfo().getMacAddress();

If you are using .NET 3.5+ you could use LINQ (Language INtegrated Query).

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

I think that this might be helpful to you.

A source release will be compiled on your own machine while a binary release must match your operating system.

source releases are more common on linux systems because linux systems can dramatically vary in cpu, installed library versions, kernelversions and nearly every linux system has a compiler installed.

binary releases are common on ms-windows systems. most windows machines do not have a compiler installed.

I didn't like bhavya's answer because of using AppDelegate inside View Controllers and setting rootViewController has no animation. And Trevor's answer has issue with flashing view controller on iOS8.

UPD 07/18/2015

AppDelegate inside View Controllers:

Changing AppDelegate state (properties) inside view controller breaks encapsulation.

Very simple hierarchy of objects in every iOS project:

AppDelegate (owns window and rootViewController)

ViewController (owns view)

It's ok that objects from the top change objects at the bottom, because they are creating them. But it's not ok if objects on the bottom change objects on top of them (I described some basic programming/OOP principle : DIP (Dependency Inversion Principle : high level module must not depend on the low level module, but they should depend on abstractions)).

If any object will change any object in this hierarchy, sooner or later there will be a mess in the code. It might be ok on the small projects but it's no fun to dig through this mess on the bit projects =]

I replicate modal controller animations using UINavigationController (tl;dr: check the project).

I'm using UINavigationController to present all controllers in my app. Initially I displayed login view controller in navigation stack with plain push/pop animation. Than I decided to change it to modal with minimal changes.

How it works:

1. Initial view controller (or self.window.rootViewController) is UINavigationController with ProgressViewController as a rootViewController. I'm showing ProgressViewController because DataModel can take some time to initialize because it inits core data stack like in this article (I really like this approach).

2. AppDelegate is responsible for getting login status updates.

3. DataModel handles user login/logout and AppDelegate is observing it's userLoggedIn property via KVO. Arguably not the best method to do this but it works for me. (Why KVO is bad, you can check in this or this article (Why Not Use Notifications? part).

4. ModalDismissAnimator and ModalPresentAnimator are used to customize default push animation.

How animators logic works:

1. AppDelegate sets itself as a delegate of self.window.rootViewController (which is UINavigationController).

2. AppDelegate returns one of animators in -[AppDelegate navigationController:animationControllerForOperation:fromViewController:toViewController:] if necessary.

3. Animators implement -transitionDuration: and -animateTransition: methods. -[ModalPresentAnimator animateTransition:]:

   - (void)animateTransition:(id<UIViewControllerContextTransitioning>)transitionContext
   {
       UIViewController *toViewController = [transitionContext viewControllerForKey:UITransitionContextToViewControllerKey];
       [[transitionContext containerView] addSubview:toViewController.view];
       CGRect frame = toViewController.view.frame;
       CGRect toFrame = frame;
       frame.origin.y = CGRectGetHeight(frame);
       toViewController.view.frame = frame;
       [UIView animateWithDuration:[self transitionDuration:transitionContext]
                        animations:^
        {
            toViewController.view.frame = toFrame;
        } completion:^(BOOL finished)
        {
            [transitionContext completeTransition:![transitionContext transitionWasCancelled]];
        }];
   }
   

Test project is here.

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

At least write the code without the bushy tree:

#!/bin/bash

PASSED=$1

if   [ -d "${PASSED}" ]
then echo "${PASSED} is a directory";
elif [ -f "${PASSED}" ]
then echo "${PASSED} is a file";
else echo "${PASSED} is not valid";
     exit 1
fi

When I put that into a file "xx.sh" and create a file "xx sh", and run it, I get:

$ cp /dev/null "xx sh"
$ for file in . xx*; do sh "$file"; done
. is a directory
xx sh is a file
xx.sh is a file
$

Given that you are having problems, you should debug the script by adding:

ls -l "${PASSED}"

This will show you what ls thinks about the names you pass the script.

It switches back because by default, when you click a link, it follows the link and loads the page. In your case, you don't want that. You can prevent it either by doing e.preventDefault(); (like Neal mentioned) or by returning false :

$(function() {
 $('.menulink').click(function(){
   $("#bg").attr('src',"img/picture1.jpg");
   return false;
 });
});

Interesting question on the differences between prevent default and return false.

In this case, return false will work just fine because the event doesn't need to be propagated.

Guess you just missed the find method in the docs:

my_array.find {|e| e.satisfies_condition? }

You need to add query.addEntity(SwitcherServiceSource.class) before calling the .list() on query.

I was having trouble on a database restore using mysqldumper (php program). I was able to get it working by changing the "mssql.timeout" setting in the php.ini. It was defaulted to 60 and I changed it to 300.

Alternatively, create a figure() object using the figsize argument and then use add_subplot to add your subplots. E.g.

import matplotlib.pyplot as plt
import numpy as np

f = plt.figure(figsize=(10,3))
ax = f.add_subplot(121)
ax2 = f.add_subplot(122)
x = np.linspace(0,4,1000)
ax.plot(x, np.sin(x))
ax2.plot(x, np.cos(x), 'r:')

Benefits of this method are that the syntax is closer to calls of subplot() instead of subplots(). E.g. subplots doesn't seem to support using a GridSpec for controlling the spacing of the subplots, but both subplot() and add_subplot() do.

You are implementing LocationListener in your activity MainActivity. The call for concurrent location updates will therefor be like this:

mLocationClient.requestLocationUpdates(mLocationRequest, this);

Be sure that the LocationListener you're implementing is from the google api, that is import this:

import com.google.android.gms.location.LocationListener;

and not this:

import android.location.LocationListener;

and it should work just fine.

It's also important that the LocationClient really is connected before you do this. I suggest you don't call it in the onCreate or onStart methods, but in onResume. It is all explained quite well in the tutorial for Google Location Api: https://developer.android.com/training/location/index.html

I think you can adapt the function to substract the two timestamps:

return  EXTRACT(MINUTE FROM 
  TO_TIMESTAMP(to_char(p_date1,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
-
  TO_TIMESTAMP(to_char(p_date2,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
);

I think you could simplify it by just using CAST(p_date as TIMESTAMP).

return  EXTRACT(MINUTE FROM cast(p_date1 as TIMESTAMP) - cast(p_date2 as TIMESTAMP));

Remember dates and timestamps are big ugly numbers inside Oracle, not what we see in the screen; we don't need to tell him how to read them. Also remember timestamps can have a timezone defined; not in this case.

Just provide the command mentioned below which will ignore executing the test cases,

mvn package -DskipTests

The answers here are correct in that IE does not support spaces when setting the title in window.open(), none seem to offer a workaround.

I removed the title from my window.open call (you can use null or ''), and hten added the following to the page being opened:

<script>document.title = 'My new title';</script>

Not ideal by any means, but this will allow you to set the title to whatever you want in all browsers.

My own library for working with ES6 iterables (blinq) allows (among other things) easy multi-level sorting

const blinq = window.blinq.blinq_x000D_
// or import { blinq } from 'blinq'_x000D_
// or const { blinq } = require('blinq')_x000D_
const dates = [{_x000D_
    day: 1, month: 10, year: 2000_x000D_
  },_x000D_
  {_x000D_
    day: 1, month: 1, year: 2000_x000D_
  },_x000D_
  {_x000D_
    day: 2, month: 1, year: 2000_x000D_
  },_x000D_
  {_x000D_
    day: 1, month: 1, year: 1999_x000D_
  },_x000D_
  {_x000D_
    day: 1, month: 1, year: 2000_x000D_
  }_x000D_
]_x000D_
const sortedDates = blinq(dates)_x000D_
  .orderBy(x => x.year)_x000D_
  .thenBy(x => x.month)_x000D_
  .thenBy(x => x.day);_x000D_
_x000D_
console.log(sortedDates.toArray())_x000D_
// or console.log([...sortedDates])

It's also possible to use java Foo | tee -a some.log. it just prints to stdout as well. Like:

user at Computer in ~
$ echo "hi" | tee -a foo.txt
hi

user at Computer in ~
$ echo "hello" | tee -a foo.txt
hello

user at Computer in ~
$ cat foo.txt
hi
hello

I bring you my solution which offers the following features:

• Supports 2 ways binding

• Auto updates the TreeViewItem.IsSelected properties (according to the SelectedItem)

• No TreeView subclassing

• Items bound to ViewModel can be of any type (even null)

1/ Paste the following code in your CS:

public class BindableSelectedItem
{
    public static readonly DependencyProperty SelectedItemProperty = DependencyProperty.RegisterAttached(
        "SelectedItem", typeof(object), typeof(BindableSelectedItem), new PropertyMetadata(default(object), OnSelectedItemPropertyChangedCallback));

    private static void OnSelectedItemPropertyChangedCallback(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        var treeView = d as TreeView;
        if (treeView != null)
        {
            BrowseTreeViewItems(treeView, tvi =>
            {
                tvi.IsSelected = tvi.DataContext == e.NewValue;
            });
        }
        else
        {
            throw new Exception("Attached property supports only TreeView");
        }
    }

    public static void SetSelectedItem(DependencyObject element, object value)
    {
        element.SetValue(SelectedItemProperty, value);
    }

    public static object GetSelectedItem(DependencyObject element)
    {
        return element.GetValue(SelectedItemProperty);
    }

    public static void BrowseTreeViewItems(TreeView treeView, Action<TreeViewItem> onBrowsedTreeViewItem)
    {
        var collectionsToVisit = new System.Collections.Generic.List<Tuple<ItemContainerGenerator, ItemCollection>> { new Tuple<ItemContainerGenerator, ItemCollection>(treeView.ItemContainerGenerator, treeView.Items) };
        var collectionIndex = 0;
        while (collectionIndex < collectionsToVisit.Count)
        {
            var itemContainerGenerator = collectionsToVisit[collectionIndex].Item1;
            var itemCollection = collectionsToVisit[collectionIndex].Item2;
            for (var i = 0; i < itemCollection.Count; i++)
            {
                var tvi = itemContainerGenerator.ContainerFromIndex(i) as TreeViewItem;
                if (tvi == null)
                {
                    continue;
                }

                if (tvi.ItemContainerGenerator.Status == System.Windows.Controls.Primitives.GeneratorStatus.ContainersGenerated)
                {
                    collectionsToVisit.Add(new Tuple<ItemContainerGenerator, ItemCollection>(tvi.ItemContainerGenerator, tvi.Items));
                }

                onBrowsedTreeViewItem(tvi);
            }

            collectionIndex++;
        }
    }

}

2/ Example of use in your XAML file

<TreeView myNS:BindableSelectedItem.SelectedItem="{Binding Path=SelectedItem, Mode=TwoWay}" />  

Usage: mysqldump [OPTIONS] database [tables]

i.e.

mysqldump -u username -p db_name table1_name table2_name table3_name > dump.sql

You can try this it will recursively find all key values in a json object and constructs as a map . You can simply get which key you want from the Map .

public static Map<String,String> parse(JSONObject json , Map<String,String> out) throws JSONException{
    Iterator<String> keys = json.keys();
    while(keys.hasNext()){
        String key = keys.next();
        String val = null;
        try{
             JSONObject value = json.getJSONObject(key);
             parse(value,out);
        }catch(Exception e){
            val = json.getString(key);
        }

        if(val != null){
            out.put(key,val);
        }
    }
    return out;
}

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

    String json = "{'ipinfo': {'ip_address': '131.208.128.15','ip_type': 'Mapped','Location': {'continent': 'north america','latitude': 30.1,'longitude': -81.714,'CountryData': {'country': 'united states','country_code': 'us'},'region': 'southeast','StateData': {'state': 'florida','state_code': 'fl'},'CityData': {'city': 'fleming island','postal_code': '32003','time_zone': -5}}}}";

    JSONObject object = new JSONObject(json);

    JSONObject info = object.getJSONObject("ipinfo");

    Map<String,String> out = new HashMap<String, String>();

    parse(info,out);

    String latitude = out.get("latitude");
    String longitude = out.get("longitude");
    String city = out.get("city");
    String state = out.get("state");
    String country = out.get("country");
    String postal = out.get("postal_code");

    System.out.println("Latitude : " + latitude + " LongiTude : " + longitude + " City : "+city + " State : "+ state + " Country : "+country+" postal "+postal);

    System.out.println("ALL VALUE " + out);

}

Output:

    Latitude : 30.1 LongiTude : -81.714 City : fleming island State : florida Country : united states postal 32003
ALL VALUE {region=southeast, ip_type=Mapped, state_code=fl, state=florida, country_code=us, city=fleming island, country=united states, time_zone=-5, ip_address=131.208.128.15, postal_code=32003, continent=north america, longitude=-81.714, latitude=30.1}

Here's a short one-liner with es6!

Set is a new data object introduced in ES6. Because Set only lets you store unique values. When you pass in an array, it will remove any duplicate values.

export const $uniquenums = [...new Set(nums)].sort(); 

If your solution doesn't have to be general, i.e. only needs to work for strings like your example, you could do:

var1=$(echo $STR | cut -f1 -d-)
var2=$(echo $STR | cut -f2 -d-)

I chose cut here because you could simply extend the code for a few more variables...

It was KB2553154. Microsoft needs to release a fix. As a developer of Excel applications we can't go to all our clients computers and delete files off them. We are getting blamed for something Microsoft caused.

Playing around with different project properties, I found that the project build order was the problem. The project that generated the files I wanted to copy was built second, but the project that was running the batch file as a post-build event was built first, so I simply attached the build event to the second project instead, and it works just fine. Thanks for your help, everyone, though.

Use the hex code for a non-breaking space. Something like this:

.breadcrumbs a:before {
    content: '>\00a0';
}

global $woocommerce;
var_dump($woocommerce->customer->get_country());
foreach ( WC()->cart->get_cart() as $cart_item_key => $cart_item ) {
    $product = new WC_product($cart_item['product_id']);
    var_dump($product);
}

We may use a CSS function calculation to calculate the size of the element and then position the child element accordingly.

Example HTML:

<div class="box">
    <span><a href="#">Some Text</a></span>
</div>

And CSS:

.box {
    display: block;
    background: #60D3E8;
    position: relative;
    width: 300px;
    height: 200px;
    text-align: center;

}
.box span {
    font: bold 20px/20px 'source code pro', sans-serif;
    position: absolute;
    left: 0;
    right: 0;
    top: calc(50% - 10px);
}
a {
    color: white;
    text-decoration: none;
}

Demo created here: https://jsfiddle.net/xnjq1t22/

This solution works well with responsive div height and width as well.

Note: The calc function is not tested for compatiblity with old browsers.

Exception clearly indicates the problem.

CompteDAOHib: No default constructor found

For spring to instantiate your bean, you need to provide a empty constructor for your class CompteDAOHib.

Schema is a way of categorising the objects in a database. It can be useful if you have several applications share a single database and while there is some common set of data that all application accesses.

FTP protocol may be blocked by your ISP firewall, try connecting via SFTP (i.e. use 22 for port num instead of 21 which is simply FTP).

For more information try this link.

You can do something like this:

<%

out.print("<p>Hey!</p>");    
out.print("<p>How are you?</p>");

%>

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

There are new methods added to java.util.Arrays to convert an array into a Java 8 stream which can then be used for summing etc.

int sum =  Arrays.stream(myIntArray)
                 .sum();

Multiplying two arrays is a little more difficult because I can't think of a way to get the value AND the index at the same time as a Stream operation. This means you probably have to stream over the indexes of the array.

//in this example a[] and b[] are same length
int[] a = ...
int[] b = ...

int[] result = new int[a.length];

IntStream.range(0, a.length)
         .forEach(i -> result[i] = a[i] * b[i]);

EDIT

Commenter @Holger points out you can use the map method instead of forEach like this:

int[] result = IntStream.range(0, a.length).map(i -> a[i] * b[i]).toArray();

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>
   <div class="form-group">
    <c:forEach items="${registrationErrors}" var="error">
    <p class="error">${error}</p>
     </c:forEach>
   </div>

Your BlockID function uses the undefined variable images, which will lead to an error. Also, you should not use an Array here - JavaScripts key-value-maps are plain objects:

function BlockID() {
    return {
        "s": "Images/Block_01.png",
        "g": "Images/Block_02.png",
        "C": "Images/Block_03.png",
        "d": "Images/Block_04.png"
    };
}

If you are using AsyncTask, probably that log message can be deceptive. If you look up in your log, you might find another error, probably one in your doInBackground() method of your AsyncTask, that is making your current Activity to blow up, and thus once the AsyncTask comes back.. well, you know the rest. Some other users already explained that here :-)

If using express...

req.ip

I was looking this up then I was like wait, I'm using express. Duh.

just add container element befor your img element just to be sure that your intersted element not the first one, tested in ie,ff

Firstly, please confirm mysql-server is installed. I have the same error when mysql-server is installed but corrupted somehow. I do the trick by uninstall mysql completely and reinstall it.

sudo apt-get remove --purge mysql*
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get install mysql-server mysql-client

You can use it via LINQ

     var selectedEditionIds = input.SelectedEditionIds.Split(",").ToArray()
                            .Where(i => !string.IsNullOrWhiteSpace(i) 
                             && int.TryParse(i,out int validNumber))
                            .Select(x=>int.Parse(x)).ToList();

a bit late, but it might be worth checking the "indicator" parameter of pd.merge.

See this other question for an example: Compare PandaS DataFrames and return rows that are missing from the first one

Try this

<input id ="btn" type="button" value="click" onclick="pay();cls()"/>

Try adding a pair of class attributes, say 'even' and 'odd', to alternating list elements, e.g.

<ul>
    <li class="even"><a href="link">Link 1</a></li>
    <li class="odd"><a href="link">Link 2</a></li>
    <li class="even"><a href="link">Link 3</a></li>
    <li class="odd"><a href="link">Link 4</a></li>
    <li class="even"><a href="link">Link 5</a></li>
</ul>

In a <style> section of the HTML page, or in a linked stylesheet, you would define those same classes, specifying your desired background colours:

li.even { background-color: red; }
li.odd { background-color: blue; }

You might want to use a template library as your needs evolve to provide you with greater flexibility and to cut down on the typing. Why type all those list elements by hand?

Maybe it´s too late but I solved this issue in a very simple way, I am using the Multicell option and the text come from a form, if I use an input field to get the text I can´t insert line breaks in any way, but if use a textarea field, the line breaks in the text area are line breaks in the multicell ... and that´s it, it works even if I use utf8_encode($text) option to preserve accents

There are a number of tools available which help debugging segmentation faults and I would like to add my favorite tool to the list: Address Sanitizers (often abbreviated ASAN).

Modern¹ compilers come with the handy -fsanitize=address flag, adding some compile time and run time overhead which does more error checking.

According to the documentation these checks include catching segmentation faults by default. The advantage here is that you get a stack trace similar to gdb's output, but without running the program inside a debugger. An example:

int main() {
  volatile int *ptr = (int*)0;
  *ptr = 0;
}

$ gcc -g -fsanitize=address main.c
$ ./a.out
AddressSanitizer:DEADLYSIGNAL

The output is slightly more complicated than what gdb would output but there are upsides:

• There is no need to reproduce the problem to receive a stack trace. Simply enabling the flag during development is enough.

• ASANs catch a lot more than just segmentation faults. Many out of bounds accesses will be caught even if that memory area was accessible to the process.

¹ That is Clang 3.1+ and GCC 4.8+.

You can do this be using a new Subject too:

Typescript:

let subject = new Subject();

get_categories(...) {
   this.http.post(...).subscribe( 
      (response) => {
         this.total = response.json();
         subject.next();
      }
   ); 

   return subject; // can be subscribed as well 
}

get_categories(...).subscribe(
   (response) => {
     // ...
   }
);

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

\i somedir/script2.sql 

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql

Use Java's replaceAll(String regex, String replacement)

For example, Use a substitution char for the quotes and then replace that char with \"

String newstring = String.replaceAll("%","\"");

or replace all instances of \" with \\\"

String newstring = String.replaceAll("\"","\\\"");

In my case the error was still there, because my system used upgraded Java. If you are using Java 10, modify the compileOptions:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_10
    targetCompatibility JavaVersion.VERSION_1_10

}

Here my approach to using fonts in asset pipeline:

1) Put all your font file under app/assets/fonts/, actually you are not restricted to put it under fonts folder name. You can put any subfolder name you like. E.g. app/assets/abc or app/assets/anotherfonts. But i highly recommend you put it under app/assets/fonts/ for better folder structure.

2) From your sass file, using the sass helper font-path to request your font assets like this

@font-face {
    font-family: 'FontAwesome';
    src: url(font-path('fontawesome-webfont.eot') + '?v=4.4.0');
    src: url(font-path('fontawesome-webfont.eot') + '?#iefix&v=4.4.0') format('embedded-opentype'),
         url(font-path('fontawesome-webfont.woff2') + '?v=4.4.0') format('woff2'),
         url(font-path('fontawesome-webfont.woff') + '?v=4.4.0') format('woff'),
         url(font-path('fontawesome-webfont.ttf') + '?v=4.4.0') format('truetype'),
         url(font-path('fontawesome-webfont.svg') + '?v=4.4.0#fontawesomeregular') format('svg');
    font-weight: normal;
    font-style: normal;
}

3) Run bundle exec rake assets:precompile from your local machine and see your application.css result. You should see something like this:

@font-face {
    font-family: 'FontAwesome';
    src: url("/assets/fontawesome-webfont-d4f5a99224154f2a808e42a441ddc9248ffe78b7a4083684ce159270b30b912a.eot" "?v=4.4.0");
    src: url("/assets/fontawesome-webfont-d4f5a99224154f2a808e42a441ddc9248ffe78b7a4083684ce159270b30b912a.eot" "?#iefix&v=4.4.0") format("embedded-opentype"), url("/assets/fontawesome-webfont-3c4a1bb7ce3234407184f0d80cc4dec075e4ad616b44dcc5778e1cfb1bc24019.woff2" "?v=4.4.0") format("woff2"), url("/assets/fontawesome-webfont-a7c7e4930090e038a280fd61d88f0dc03dad4aeaedbd8c9be3dd9aa4c3b6f8d1.woff" "?v=4.4.0") format("woff"), url("/assets/fontawesome-webfont-1b7f3de49d68b01f415574ebb82e6110a1d09cda2071ad8451bdb5124131a292.ttf" "?v=4.4.0") format("truetype"), url("/assets/fontawesome-webfont-7414288c272f6cc10304aa18e89bf24fb30f40afd644623f425c2c3d71fbe06a.svg" "?v=4.4.0#fontawesomeregular") format("svg");

It's a new year and there's a new mismatch between the version of protobuf in Homebrew and the cutting edge release. As of February 2016, brew install protobuf will give you version 2.6.1.

If you want the 3.0 beta release instead, you can install it with:

Hive tables are stored in the Hive warehouse directory. By default, MapR configures the Hive warehouse directory to be /user/hive/warehouse under the root volume. This default is defined in the $HIVE_HOME/conf/hive-default.xml.

In sql developer define properties by default "ON". If it is "OFF" any case, use below steps.

set define on; define batchNo='123'; update TABLE_NAME SET IND1 = 'Y', IND2 = 'Y' WHERE BATCH_NO = '&batchNo';

Also:

angular.module('App.filters', [])
    .filter('joinBy', function () {
        return function (input,delimiter) {
            return (input || []).join(delimiter || ',');
        };
    });

And in template:

{{ itemsArray | joinBy:',' }}

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

this will do your job

Here's a solution that keeps things within a dplyr pipe chain. You sort the data in advance, and then using mutate_at to convert to a factor. I've modified the data slightly to show how this solution can be applied generally, given data that can be sensibly sorted:

# the data
temp <- data.frame(type=rep(c("T", "F", "P"), 4),
                    size=rep(c("50%", "100%", "200%", "150%"), each=3), # cannot sort this
                    size_num = rep(c(.5, 1, 2, 1.5), each=3), # can sort this
                    amount=c(48.4, 48.1, 46.8, 
                             25.9, 26.0, 24.9,
                             20.8, 21.5, 16.5,
                             21.1, 21.4, 20.1))

temp %>% 
  arrange(size_num) %>% # sort
  mutate_at(vars(size), funs(factor(., levels=unique(.)))) %>% # convert to factor

  ggplot() + 
  geom_bar(aes(x = type, y=amount, fill=type), 
           position="dodge", stat="identity") + 
  facet_grid(~ size)

You can apply this solution to arrange the bars within facets, too, though you can only choose a single, preferred order:

    temp %>% 
  arrange(size_num) %>%
  mutate_at(vars(size), funs(factor(., levels=unique(.)))) %>%
  arrange(desc(amount)) %>%
  mutate_at(vars(type), funs(factor(., levels=unique(.)))) %>%
  ggplot() + 
  geom_bar(aes(x = type, y=amount, fill=type), 
           position="dodge", stat="identity") + 
  facet_grid(~ size)


  ggplot() + 
  geom_bar(aes(x = type, y=amount, fill=type), 
           position="dodge", stat="identity") + 
  facet_grid(~ size)

Why not just do this take 010010001001001 split it into two bits 8 letter each (01001000, 01001001). Then issue the powers

01001000. 01001001.

The first 8 ignore the first three they determine if it's capital or not, the go right to left doing powers of 2 (2^1, 2^2 2^3 2^4 2^5). So then add all the ones up , there's only one, and it = 8, and te eight letter in the alphabet is h so our first bit is the letter h, try it on the other bit

It's 2016 or later and things have progressed. This matches Unicode alphanumeric strings:

^[\\p{IsAlphabetic}\\p{IsDigit}]+$

See the reference (section "Classes for Unicode scripts, blocks, categories and binary properties"). There's also this answer that I found helpful.

Generally speaking, jQuery plugins are namespaces on the jQuery scope. You could run a simple check to see if the namespace exists:

 if(jQuery().pluginName) {
     //run plugin dependent code
 }

dateJs however is not a jQuery plugin. It modifies/extends the javascript date object, and is not added as a jQuery namespace. You could check if the method you need exists, for example:

 if(Date.today) {
      //Use the dateJS today() method
 }

But you might run into problems where the API overlaps the native Date API.

Here's an example where I found the replace( ) function helpful for giving me insight. The problem required a long integer vector be changed into a character vector and with its integers replaced by given character values.

## figuring out replace( )
(test <- c(rep(1,3),rep(2,2),rep(3,1)))

which looks like

[1] 1 1 1 2 2 3

and I want to replace every 1 with an A and 2 with a B and 3 with a C

letts <- c("A","B","C")

so in my own secret little "dirty-verse" I used a loop

for(i in 1:3)
{test <- replace(test,test==i,letts[i])}

which did what I wanted

test
[1] "A" "A" "A" "B" "B" "C"

In the first sentence I purposefully left out that the real objective was to make the big vector of integers a factor vector and assign the integer values (levels) some names (labels).

So another way of doing the replace( ) application here would be

(test <- factor(test,labels=letts))
[1] A A A B B C
Levels: A B C

java.lang.ClassNotFoundException: oracle.jdbc.driver.OracleDriver

Just add the ojdbc14.jar to your classpath.

The following are the steps that are given below to add ojdbc14.jar in eclipse:

1) Inside your project

2) Libraries

3) Right click on JRE System Library

4) Build Path

5) Select Configure Build Path

6) Click on Add external JARs...

7) C:\oraclexe\app\oracle\product\10.2.0\server\jdbc\lib

8) Here you will get ojdbc14.jar

9) select here

10) open

11) ok

save and run the program you will get output.

If you are testing on local PC, it won't work. To test Ajax example you need to place the HTML files on a web server.

If you are using python 3.6 and newer then you can use f-strings to do the task like this.

print(f"I have {card.price}")

just include f in front of your string and add the variable inside curly braces { }.

Refer to a blog The new f-strings in Python 3.6: written by Christoph Zwerschke which includes execution times of the various method.

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

A build, as Makefile understands it, consists of a lot of targets. For example, to build a project you might need

1. Build file1.o out of file1.c
2. Build file2.o out of file2.c
3. Build file3.o out of file3.c
4. Build executable1 out of file1.o and file3.o
5. Build executable2 out of file2.o

If you implemented this workflow with makefile, you could make each of the targets separately. For example, if you wrote

make file1.o

it would only build that file, if necessary.

The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files. For the example above, building all necessary is building executables, the other files being pulled in as dependencies. So in the makefile it looks like this:

all: executable1 executable2

all target is usually the first in the makefile, since if you just write make in command line, without specifying the target, it will build the first target. And you expect it to be all.

all is usually also a .PHONY target. Learn more here.

I'm using Django 1.7

Create a SlugField in your model like this:

slug = models.SlugField()

Then in admin.py define prepopulated_fields;

class ArticleAdmin(admin.ModelAdmin):
    prepopulated_fields = {"slug": ("title",)}

If you look at the scope of the variable 'hoursWorked' you will see that it is a member of the class (declared as private int)

The two variables you are having trouble with are passed as parameters to the constructor.

The error message is because 'hours' is out of scope in the setter.

Check out this w3schools page about "HTML URL Encoding Reference": https://www.w3schools.com/tags/ref_urlencode.asp

for / you would escape with %2F

In addition to the solution already provided, you can replace all the columns while you are reading the file. We can use names and header=0 to do that.

First, we create a list of the names that we like to use as our column names:

import pandas as pd

ufo_cols = ['city', 'color reported', 'shape reported', 'state', 'time']
ufo.columns = ufo_cols

ufo = pd.read_csv('link to the file you are using', names = ufo_cols, header = 0)

In this case, all the column names will be replaced with the names you have in your list.

The type comes after the name in TypeScript, partly because types are optional.

So your line:

HTMLElement el = document.getElementById('content');

Needs to change to:

const el: HTMLElement = document.getElementById('content');

Back in 2013, the type HTMLElement would have been inferred from the return value of getElementById, this is still the case if you aren't using strict null checks (but you ought to be using the strict modes in TypeScript). If you are enforcing strict null checks you will find the return type of getElementById has changed from HTMLElement to HTMLElement | null. The change makes the type more correct, because you don't always find an element.

So when using type mode, you will be encouraged by the compiler to use a type assertion to ensure you found an element. Like this:

const el: HTMLElement | null = document.getElementById('content');

if (el) {
  const definitelyAnElement: HTMLElement = el;
}

I have included the types to demonstrate what happens when you run the code. The interesting bit is that el has the narrower type HTMLElement within the if statement, due to you eliminating the possibility of it being null.

You can do exactly the same thing, with the same resulting types, without any type annotations. They will be inferred by the compiler, thus saving all that extra typing:

const el = document.getElementById('content');

if (el) {
  const definitelyAnElement = el;
}

What do you mean by better way:

more readable:

List<String> list = new ArrayList<String>(Arrays.asList(array));

less memory consumption, and maybe faster (but definitely not thread safe):

public static List<String> toList(String[] array) {
    if (array==null) {
       return new ArrayList(0);
    } else {
       int size = array.length;
       List<String> list = new ArrayList(size);
       for(int i = 0; i < size; i++) {
          list.add(array[i]);
       }
       return list;
    }
}

Btw: here is a bug in your first example:

array.length will raise a null pointer exception if array is null, so the check if (array!=null) must be done first.

It is called the extended call syntax. From the documentation:

If the syntax *expression appears in the function call, expression must evaluate to a sequence. Elements from this sequence are treated as if they were additional positional arguments; if there are positional arguments x1,..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

and:

If the syntax **expression appears in the function call, expression must evaluate to a mapping, the contents of which are treated as additional keyword arguments. In the case of a keyword appearing in both expression and as an explicit keyword argument, a TypeError exception is raised.

hours (h) calculated by floor division (by //) of seconds by 3600 (60 min/hr * 60 sec/min)

minutes (m) calculated by floor division of remaining seconds (remainder from hour calculation, by %) by 60 (60 sec/min)

similarly, seconds (s) by remainder of hour and minutes calculation.

Rest is just string formatting!

def hms(seconds):
    h = seconds // 3600
    m = seconds % 3600 // 60
    s = seconds % 3600 % 60
    return '{:02d}:{:02d}:{:02d}'.format(h, m, s)

print(hms(7500))  # Should print 02h05m00s

Leveraging from the good answers above and assuming you were only using plt as in

import matplotlib.pyplot as plt

then you can get all four plot limits using plt.axis() as in the following example.

import matplotlib.pyplot as plt

x = [1, 2, 3, 4, 5, 6, 7, 8]  # fake data
y = [1, 2, 3, 4, 3, 2, 5, 6]

plt.plot(x, y, 'k')

xmin, xmax, ymin, ymax = plt.axis()

s = 'xmin = ' + str(round(xmin, 2)) + ', ' + \
    'xmax = ' + str(xmax) + '\n' + \
    'ymin = ' + str(ymin) + ', ' + \
    'ymax = ' + str(ymax) + ' '

plt.annotate(s, (1, 5))

plt.show()

The above code should produce the following output plot.

When you typed in the mongod command, did you also give it a path? This is usually the issue. You don't have to bother with the conf file. simply type

mongod --dbpath="put your path to where you want it to save the working area for your database here!! without these silly quotations marks I may also add!"

example: mongod --dbpath=C:/Users/kyles2/Desktop/DEV/mongodb/data

That is my path and don't forget if on windows to flip the slashes forward if you copied it from the or it won't work!

Yes, there is one. It is an eclipse-plugin called Visual Editor. You can download it here

The default condition can be anyplace within the switch that a case clause can exist. It is not required to be the last clause. I have seen code that put the default as the first clause. The case 2: gets executed normally, even though the default clause is above it.

As a test, I put the sample code in a function, called test(int value){} and ran:

  printf("0=%d\n", test(0));
  printf("1=%d\n", test(1));
  printf("2=%d\n", test(2));
  printf("3=%d\n", test(3));
  printf("4=%d\n", test(4));

The output is:

0=2
1=1
2=4
3=8
4=10

I don't mean this to sound snarky, but it doesn't matter.

Seriously.

Look at the things that are important: your project, your code, your job, your personal life. None of them are going to have their success rest on whether or not you use the "this" keyword to qualify access to fields. The this keyword will not help you ship on time. It's not going to reduce bugs, it's not going to have any appreciable effect on code quality or maintainability. It's not going to get you a raise, or allow you to spend less time at the office.

It's really just a style issue. If you like "this", then use it. If you don't, then don't. If you need it to get correct semantics then use it. The truth is, every programmer has his own unique programing style. That style reflects that particular programmer's notions of what the "most aesthetically pleasing code" should look like. By definition, any other programmer who reads your code is going to have a different programing style. That means there is always going to be something you did that the other guy doesn't like, or would have done differently. At some point some guy is going to read your code and grumble about something.

I wouldn't fret over it. I would just make sure the code is as aesthetically pleasing as possible according to your own tastes. If you ask 10 programmers how to format code, you are going to get about 15 different opinions. A better thing to focus on is how the code is factored. Are things abstracted right? Did I pick meaningful names for things? Is there a lot of code duplication? Are there ways I can simplify stuff? Getting those things right, I think, will have the greatest positive impact on your project, your code, your job, and your life. Coincidentally, it will probably also cause the other guy to grumble the least. If your code works, is easy to read, and is well factored, the other guy isn't going to be scrutinizing how you initialize fields. He's just going to use your code, marvel at it's greatness, and then move on to something else.

It is very dependent of the engine that you use for generating html files. If you are using Hugo for generating htmls you have to write down like this:

<a href="https://example.com" target="_blank" rel="noopener"><span>Example Text</span> </a>.

Wrap it in double quotes

alter user "dell-sys" with password 'Pass@133';

Notice that you will have to use the same case you used when you created the user using double quotes. Say you created "Dell-Sys" then you will have to issue exact the same whenever you refer to that user.

I think the best you do is to drop that user and recreate without illegal identifier characters and without double quotes so you can later refer to it in any case you want.

I've come up with an awkward but functional solution for my problem. It works for a one-dimensional array (more dimensions would be tricky) and input that fits into a varchar:

  declare pos int;           -- Keeping track of the next item's position
  declare item varchar(100); -- A single item of the input
  declare breaker int;       -- Safeguard for while loop 

  -- The string must end with the delimiter
  if right(inputString, 1) <> '|' then
     set inputString = concat(inputString, '|');
  end if;

  DROP TABLE IF EXISTS MyTemporaryTable;
  CREATE TEMPORARY TABLE MyTemporaryTable ( columnName varchar(100) );
  set breaker = 0;

  while (breaker < 2000) && (length(inputString) > 1) do
     -- Iterate looking for the delimiter, add rows to temporary table.
     set breaker = breaker + 1;
     set pos = INSTR(inputString, '|');
     set item = LEFT(inputString, pos - 1);
     set inputString = substring(inputString, pos + 1);
     insert into MyTemporaryTable values(item);
  end while;

For example, input for this code could be the string Apple|Banana|Orange. MyTemporaryTable will be populated with three rows containing the strings Apple, Banana, and Orange respectively.

I thought the slow speed of string handling would render this approach useless, but it was quick enough (only a fraction of a second for a 1,000 entries array).

Hope this helps somebody.

Use Simple math to resize the image . either you can resize ImageView or you can resize drawable image than set on ImageView . find the width and height of your bitmap which you want to set on ImageView and call the desired method. suppose your width 500 is greater than height than call method

//250 is the width you want after resize bitmap
Bitmat bmp = BitmapScaler.scaleToFitWidth(bitmap, 250) ;
ImageView image = (ImageView) findViewById(R.id.picture);
image.setImageBitmap(bmp);

You use this class for resize bitmap.

public class BitmapScaler{
// Scale and maintain aspect ratio given a desired width
// BitmapScaler.scaleToFitWidth(bitmap, 100);
 public static Bitmap scaleToFitWidth(Bitmap b, int width)
  {
    float factor = width / (float) b.getWidth();
    return Bitmap.createScaledBitmap(b, width, (int) (b.getHeight() * factor), true);
  }


  // Scale and maintain aspect ratio given a desired height
  // BitmapScaler.scaleToFitHeight(bitmap, 100);
  public static Bitmap scaleToFitHeight(Bitmap b, int height)
  {
    float factor = height / (float) b.getHeight();
    return Bitmap.createScaledBitmap(b, (int) (b.getWidth() * factor), height, true);
   }
 }

xml code is

<ImageView
android:id="@+id/picture"
android:layout_width="250dp"
android:layout_height="250dp"
android:layout_gravity="center_horizontal"
android:layout_marginTop="20dp"
android:adjustViewBounds="true"
android:scaleType="fitcenter" />

For anyone who is looking for solutions here, I had a similar issue with C++: malloc(): smallbin double linked list corrupted:

This was due to a function not returning a value it was supposed to.

std::vector<Object> generateStuff(std::vector<Object>& target> {
  std::vector<Object> returnValue;
  editStuff(target);
  // RETURN MISSING
}

Don't know why this was able to compile after all. Probably there was a warning about it.

java.lang.Enum defines several useful methods, which is available to all enumeration type in Java:

• You can use name() method to get name of any Enum constants. String literal used to write enum constants is their name.
• Similarly values() method can be used to get an array of all Enum constants from an Enum type.
• And for the asked question, you can use valueOf() method to convert any String to Enum constant in Java, as shown below.

public class EnumDemo06 {
    public static void main(String args[]) {
        Gender fromString = Gender.valueOf("MALE");
        System.out.println("Gender.MALE.name() : " + fromString.name());
    }

    private enum Gender {
        MALE, FEMALE;
    }
}

Output:
Gender.MALE.name() : MALE

In this code snippet, valueOf() method returns an Enum constant Gender.MALE, calling name on that returns "MALE".

Something like this should do it:

select * from yourtable where datepart(month,field) = @month and datepart(year,field) = @year

Alternatively you could split month and year out into their own columns when creating the record and then select against them.

One alternate way if file contains strings without spaces with 1string each line:

fileItemString=$(cat  filename |tr "\n" " ")

fileItemArray=($fileItemString)

Check:

Print whole Array:

${fileItemArray[*]}

Length=${#fileItemArray[@]}

Making a small tweak to the inside function and using lapply on an index instead of the actual list itself gets this doing what you want

x <- c("yes", "no", "maybe", "no", "no", "yes")
y <- c("red", "blue", "green", "green", "orange")
list.xy <- list(x=x, y=y)

WORD.C <- function(WORDS){
  require(wordcloud)

  L2 <- lapply(WORDS, function(x) as.data.frame(table(x), stringsAsFactors = FALSE))

  # Takes a dataframe and the text you want to display
  FUN <- function(X, text){
    windows() 
    wordcloud(X[, 1], X[, 2], min.freq=1)
    mtext(text, 3, padj=-4.5, col="red")  #what I'm trying that isn't working
  }

  # Now creates the sequence 1,...,length(L2)
  # Loops over that and then create an anonymous function
  # to send in the information you want to use.
  lapply(seq_along(L2), function(i){FUN(L2[[i]], names(L2)[i])})

  # Since you asked about loops
  # you could use i in seq_along(L2) 
  # instead of 1:length(L2) if you wanted to
  #for(i in 1:length(L2)){
  #  FUN(L2[[i]], names(L2)[i])
  #}
}

x86 is rather broad range of devices.

For totally generic x86 target, an assembly block with "rep movsd" could blast out zeros to memory 32-bits at time. Try to make sure the bulk of this work is DWORD aligned.

For chips with mmx, an assembly loop with movq could hit 64bits at a time.

You might be able to get a C/C++ compiler to use a 64-bit write with a pointer to a long long or _m64. Target must be 8 byte aligned for the best performance.

for chips with sse, movaps is fast, but only if the address is 16 byte aligned, so use a movsb until aligned, and then complete your clear with a loop of movaps

Win32 has "ZeroMemory()", but I forget if thats a macro to memset, or an actual 'good' implementation.

function abc() {
    var color = document.getElementById("test").style.color;
    if (color === "red")
         document.getElementById("test").style.color="black";
    else
         document.getElementById("test").style.color="red";
}

try a this one:

...
View view = inflater.inflate(R.layout.active_slide, this);
view.setMinimumWidth(200);

You have no width set and there is not content in the divs is one issue. The other is that the way html works... when all three of fixed, is that the hierarchy goes from bottom to top... so the content is on top of the header since they are both fixed... so in this case you need to declare a z-index on the header... but I wouldn't do that... leave that one relative so it can scroll normally.

Go mobile first on this... FIDDLE HERE

I suggest not using an array unless you have multiple objects to consider. There isn't anything wrong this statement:

var myMappings = {
    "Name": 0.1,
    "Phone": 0.1,
    "Address": 0.5,
    "Zip": 0.1,
    "Comments": 0.2
};

for (var col in myMappings) {
    alert((myMappings[col] * 100) + "%");
}

request.stream is the stream of raw data passed to the application by the WSGI server. No parsing is done when reading it, although you usually want request.get_data() instead.

data = request.stream.read()

The stream will be empty if it was previously read by request.data or another attribute.

"Is there also a way to pass coords directly to google maps to display?"

I have found that if I pass a URL containing the coords to the browser, Android asks if I want the browser or the Maps app, as long as the user hasn't chosen the browser as the default. See my answer here for more info on the formating of the URL.

I guess if you used an intent to launch the Maps App with the coords, that would work also.

Are there any performance benefits to using one over the other?

Keep in mind that there is no JavaScript engine yet that natively supports ES6 modules. You said yourself that you are using Babel. Babel converts import and export declaration to CommonJS (require/module.exports) by default anyway. So even if you use ES6 module syntax, you will be using CommonJS under the hood if you run the code in Node.

There are technical differences between CommonJS and ES6 modules, e.g. CommonJS allows you to load modules dynamically. ES6 doesn't allow this, but there is an API in development for that.

Since ES6 modules are part of the standard, I would use them.

Update 2020

Since Node v12, support for ES modules is enabled by default, but it's still experimental at the time of writing this. Files including node modules must either end in .mjs or the nearest package.json file must contain "type": "module". The Node documentation has a ton more information, also about interop between CommonJS and ES modules.

Performance-wise there is always the chance that newer features are not as well optimized as existing features. However, since module files are only evaluated once, the performance aspect can probably be ignored. In the end you have to run benchmarks to get a definite answer anyway.

ES modules can be loaded dynamically via the import() function. Unlike require, this returns a promise.

For python 3.5+ it is recommended that you use the run function from the subprocess module. This returns a CompletedProcess object, from which you can easily obtain the output as well as return code. Since you are only interested in the output, you can write a utility wrapper like this.

from subprocess import PIPE, run

def out(command):
    result = run(command, stdout=PIPE, stderr=PIPE, universal_newlines=True, shell=True)
    return result.stdout

my_output = out("echo hello world")
# Or
my_output = out(["echo", "hello world"])

I just learned something new thanks to Artiso. I gave each module a name in the properties box. These names were also what I declared in the module. When I tried to call my second module, I kept getting an error: Compile error: Expected variable or procedure, not module

After reading Artiso's comment above about not having the same names, I renamed my second module, called it from the first, and problem solved. Interesting stuff! Thanks for the info Artiso!

In case my experience is unclear:

Module Name: AllFSGroupsCY Public Sub AllFSGroupsCY()

Module Name: AllFSGroupsPY Public Sub AllFSGroupsPY()

From AllFSGroupsCY()

Public Sub FSGroupsCY()

    AllFSGroupsPY 'will error each time until the properties name is changed

End Sub

I have come across this error when the app resides on a network share, and the device (laptop, tablet, ...) becomes disconnected from the network while the app is in use. In my case, it was due to a Surface tablet going out of wireless range. No problems after installing a better WAP.

For anyone who likes Extension methods, this one does the trick for us.

using System.Text;

namespace System
{
    public static class StringExtension
    {
        private static readonly ASCIIEncoding asciiEncoding = new ASCIIEncoding();

        public static string ToAscii(this string dirty)
        {
            byte[] bytes = asciiEncoding.GetBytes(dirty);
            string clean = asciiEncoding.GetString(bytes);
            return clean;
        }
    }
}

(System namespace so it's available pretty much automatically for all of our strings.)

This is realy old post but here is one my update what I made using correct answer. My solution also use jQuery.

Point of this is to use proper print view, include all stylesheets for the proper formatting and also to be supported in the most browsers.

function PrintElem(elem, title, offset)
{
    // Title constructor
    title = title || $('title').text();
    // Offset for the print
    offset = offset || 0;

    // Loading start
    var dStart = Math.round(new Date().getTime()/1000),
        $html = $('html');
        i = 0;

    // Start building HTML
    var HTML = '<html';

    if(typeof ($html.attr('lang')) !== 'undefined') {
        HTML+=' lang=' + $html.attr('lang');
    }

    if(typeof ($html.attr('id')) !== 'undefined') {
        HTML+=' id=' + $html.attr('id');
    }

    if(typeof ($html.attr('xmlns')) !== 'undefined') {
        HTML+=' xmlns=' + $html.attr('xmlns');
    }

    // Close HTML and start build HEAD
    HTML+='><head>';

    // Get all meta tags
    $('head > meta').each(function(){
        var $this = $(this),
            $meta = '<meta';

        if(typeof ($this.attr('charset')) !== 'undefined') {
            $meta+=' charset=' + $this.attr('charset');
        }

        if(typeof ($this.attr('name')) !== 'undefined') {
            $meta+=' name=' + $this.attr('name');
        }

        if(typeof ($this.attr('http-equiv')) !== 'undefined') {
            $meta+=' http-equiv=' + $this.attr('http-equiv');
        }

        if(typeof ($this.attr('content')) !== 'undefined') {
            $meta+=' content=' + $this.attr('content');
        }

        $meta+=' />';

        HTML+= $meta;
        i++;

    }).promise().done(function(){

        // Insert title
        HTML+= '<title>' + title  + '</title>';

        // Let's pickup all CSS files for the formatting
        $('head > link[rel="stylesheet"]').each(function(){
            HTML+= '<link rel="stylesheet" href="' + $(this).attr('href') + '" />';
            i++;
        }).promise().done(function(){
            // Print setup
            HTML+= '<style>body{display:none;}@media print{body{display:block;}}</style>';

            // Finish HTML
            HTML+= '</head><body>';
            HTML+= '<h1 class="text-center mb-3">' + title  + '</h1>';
            HTML+= elem.html();
            HTML+= '</body></html>';

            // Open new window
            var printWindow = window.open('', 'PRINT', 'height=' + $(window).height() + ',width=' + $(window).width());
            // Append new window HTML
            printWindow.document.write(HTML);

            printWindow.document.close(); // necessary for IE >= 10
            printWindow.focus(); // necessary for IE >= 10*/
console.log(printWindow.document);
            /* Make sure that page is loaded correctly */
            $(printWindow).on('load', function(){                   
                setTimeout(function(){
                    // Open print
                    printWindow.print();

                    // Close on print
                    setTimeout(function(){
                        printWindow.close();
                        return true;
                    }, 3);

                }, (Math.round(new Date().getTime()/1000) - dStart)+i+offset);
            });
        });
    });
}

Later you simple need something like this:

$(document).on('click', '.some-print', function() {
    PrintElem($(this), 'My Print Title');
    return false;
});

Try it.

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

The possible reason could be deletion of the existing db file and migrations folder you can use python manage.py makemigrations <app_name> this should work. I once faced a similar problem.

index.php

$url = 'http://[host]/test.php';
$json = json_encode(['name' => 'Jhonn', 'phone' => '128000000000']);

$options = ['http' => [
    'method' => 'POST',
    'header' => 'Content-type:application/json',
    'content' => $json
]];

$context = stream_context_create($options);
$response = file_get_contents($url, false, $context);

test.php

$raw = file_get_contents('php://input');
$data = json_decode($raw, true);
echo $data['name']; // Jhonn

You need the textFX plugin. Then, just follow these instructions:

Paste the text into Notepad++ (CTRL+V). ...
Mark all the text (CTRL+A). ...
Click TextFX ? Click TextFX Tools ? Click Sort lines case insensitive (at column)
Duplicates and blank lines have been removed and the data has been sorted alphabetically.

Personally, I would use sort -i -u source >dest instead of notepad++

Reflection e.g.:

public class PrivateObject {

  private String privateString = null;

  public PrivateObject(String privateString) {
    this.privateString = privateString;
  }
}
PrivateObject privateObject = new PrivateObject("The Private Value");

Field privateStringField = PrivateObject.class.
            getDeclaredField("privateString");

privateStringField.setAccessible(true);

String fieldValue = (String) privateStringField.get(privateObject);
System.out.println("fieldValue = " + fieldValue);

here is the sample code to draw image on canvas-

$("#selectedImage").change(function(e) {

var URL = window.URL;
var url = URL.createObjectURL(e.target.files[0]);
img.src = url;

img.onload = function() {
    var canvas = document.getElementById("myCanvas");
    var ctx = canvas.getContext("2d");        

    ctx.clearRect(0, 0, canvas.width, canvas.height);
    ctx.drawImage(img, 0, 0, 500, 500);
}});

In the above code selectedImage is an input control which can be used to browse image on system. For more details of sample code to draw image on canvas while maintaining the aspect ratio:

NEQ - not equal

LSS - less than

LEQ - less than or equal

GTR - greater than

GEQ - greater than or equal

Yes. Just as the error said, in HTML, attributes are #PCDATA meaning they're parsed. This means you can use character entities in the attributes. Using & by itself is wrong and if not for lenient browsers and the fact that this is HTML not XHTML, would break the parsing. Just escape it as & and everything would be fine.

HTML5 allows you to leave it unescaped, but only when the data that follows does not look like a valid character reference. However, it's better just to escape all instances of this symbol than worry about which ones should be and which ones don't need to be.

Keep this point in mind; if you're not escaping & to &amp;, it's bad enough for data that you create (where the code could very well be invalid), you might also not be escaping tag delimiters, which is a huge problem for user-submitted data, which could very well lead to HTML and script injection, cookie stealing and other exploits.

Please just escape your code. It will save you a lot of trouble in the future.

While "use a stack" might work as the answer to contrived interview question, in reality, it's just doing explicitly what a recursive program does behind the scenes.

Recursion uses the programs built-in stack. When you call a function, it pushes the arguments to the function onto the stack and when the function returns it does so by popping the program stack.

DefaultForeColor is enough for this statement. This property gets the default foreground color of the control.

lblExample.ForeColor = DefaultForeColor;

Check this also:

This problem occurs because the Web site does not have the Directory Browsing feature enabled, and the default document is not configured. To resolve this problem, use one of the following methods:

• Method 1: Enable the Directory Browsing feature in IIS (Recommended)
• Method 2: Add a default document Method
• Method 3: Enable the Directory Browsing feature in IIS Express

When accessing the field value, pass the instance rather than null.

Why not use code generation here? Eclipse, for example, will generate a reasoble toString implementation for you.

The second form (creating an HTTP server yourself, instead of having Express create one for you) is useful if you want to reuse the HTTP server, for example to run socket.io within the same HTTP server instance:

var express = require('express');
var app     = express();
var server  = require('http').createServer(app);
var io      = require('socket.io').listen(server);
...
server.listen(1234);

However, app.listen() also returns the HTTP server instance, so with a bit of rewriting you can achieve something similar without creating an HTTP server yourself:

var express   = require('express');
var app       = express();

// app.use/routes/etc...

var server    = app.listen(3033);
var io        = require('socket.io').listen(server);

io.sockets.on('connection', function (socket) {
  ...
});

Aside from pandas, Apache pyarrow also provides way to transform parquet to dataframe

The code is simple, just type:

import pyarrow.parquet as pq

df = pq.read_table(source=your_file_path).to_pandas()

For more information, see the document from Apache pyarrow Reading and Writing Single Files

if none of the above is working you can use this->

idAssignedToEntryWidget.delete(first = 0, last = UpperLimitAssignedToEntryWidget)

for e.g. ->

id assigned is = en then

en.delete(first =0, last =100)

Unfortunately the Windows Mobile Device Center stopped working out of the box after the Creators Update for Windows 10. The application won't open and therefore it's impossible to get the sync working. In order to get it running now we need to modify the ActiveSync registry settings. Create a BAT file with the following contents and run it as administrator:

REG ADD HKLM\SYSTEM\CurrentControlSet\Services\RapiMgr /v SvcHostSplitDisable /t REG_DWORD /d 1 /f
REG ADD HKLM\SYSTEM\CurrentControlSet\Services\WcesComm /v SvcHostSplitDisable /t REG_DWORD /d 1 /f

Restart the computer and everything should work.

Simplest definition of the Coalesce() function could be:

Coalesce() function evaluates all passed arguments then returns the value of the first instance of the argument that did not evaluate to a NULL.

Note: it evaluates ALL parameters, i.e. does not skip evaluation of the argument(s) on the right side of the returned/NOT NULL parameter.

Syntax:

Coalesce(arg1, arg2, argN...)

Beware: Apart from the arguments that evaluate to NULL, all other (NOT-NULL) arguments must either be of same datatype or must be of matching-types (that can be "implicitly auto-converted" into a compatible datatype), see examples below:

PRINT COALESCE(NULL, ('str-'+'1'), 'x')  --returns 'str-1, works as all args (excluding NULLs) are of same VARCHAR type.
--PRINT COALESCE(NULL, 'text', '3', 3)    --ERROR: passed args are NOT matching type / can't be implicitly converted.
PRINT COALESCE(NULL, 3, 7.0/2, 1.99)      --returns 3.0, works fine as implicit conversion into FLOAT type takes place.
PRINT COALESCE(NULL, '1995-01-31', 'str') --returns '2018-11-16', works fine as implicit conversion into VARCHAR occurs.

DECLARE @dt DATE = getdate()
PRINT COALESCE(NULL, @dt, '1995-01-31')  --returns today's date, works fine as implicit conversion into DATE type occurs.

--DATE comes before VARCHAR (works):
PRINT COALESCE(NULL, @dt, 'str')      --returns '2018-11-16', works fine as implicit conversion of Date into VARCHAR occurs.

--VARCHAR comes before DATE (does NOT work):
PRINT COALESCE(NULL, 'str', @dt)      --ERROR: passed args are NOT matching type, can't auto-cast 'str' into Date type.

HTH

It can be that your resources directory is not added to classpath when creating a project via Spring Initializr. So your application is never loading the application.properties file that you have configured.

To make a quick test if this is the case, add the following to your application.properties file:

server.port=8081

Now when running your application you should see in the spring boot console output something like this:

INFO  o.s.b.w.e.tomcat.TomcatWebServer - Tomcat started on port(s): **8081** (http) with context path ''

If your port is still default 8080 and not changed to 8081, your application.properties files is obviously not loading.

You can also check if your application runs with gradle bootRun from command line. Which most likely will be work.

Solution:

1. Close IntelliJ, then inside your project folder delete the ".idea" folder
2. Reimport your project to IntelliJ like following: "Import Project" -> "select ONLY your build.gradle file to import". (IntelliJ will automatically grab the rest)
3. build and run your application again

See official answer by IntelliJ Support: IDEA-221673

If you look at the down arrow in environment tab. The attached file can appear multiple times. You may need to highlight and run detach(filename) several times until all cases are gone then attach(newfilename) should have no output message.

About alexK7 benchmarks. I tried them and got similar results, but when the range of values is 1 million the cases using std::sort (f1) and using std::unordered_set (f5) produce similar time. When the range of values is 10 million f1 is faster than f5.

If the range of values is limited and the values are unsigned int, it is possible to use std::vector, the size of which corresponds to the given range. Here is the code:

void DeleteDuplicates_vector_bool(std::vector<unsigned>& v, unsigned range_size)
{
    std::vector<bool> v1(range_size);
    for (auto& x: v)
    {
       v1[x] = true;    
    }
    v.clear();

    unsigned count = 0;
    for (auto& x: v1)
    {
        if (x)
        {
            v.push_back(count);
        }
        ++count;
    }
}

For Windows 10 it is:

GCC comes with a compiler runtime library (libgcc) which it uses for (among other things) providing a low-level OS abstraction for multithreading related functionality in the languages it supports. The most relevant example is libstdc++'s C++11 <thread>, <mutex>, and <future>, which do not have a complete implementation when GCC is built with its internal Win32 threading model. MinGW-w64 provides a winpthreads (a pthreads implementation on top of the Win32 multithreading API) which GCC can then link in to enable all the fancy features.

I must stress this option does not forbid you to write any code you want (it has absolutely NO influence on what API you can call in your code). It only reflects what GCC's runtime libraries (libgcc/libstdc++/...) use for their functionality. The caveat quoted by @James has nothing to do with GCC's internal threading model, but rather with Microsoft's CRT implementation.

To summarize:

• posix: enable C++11/C11 multithreading features. Makes libgcc depend on libwinpthreads, so that even if you don't directly call pthreads API, you'll be distributing the winpthreads DLL. There's nothing wrong with distributing one more DLL with your application.
• win32: No C++11 multithreading features.

Neither have influence on any user code calling Win32 APIs or pthreads APIs. You can always use both.

Quick and dirty technique:

    static byte[] StreamToByteArray(Stream inputStream)
    {
        if (!inputStream.CanRead)
        {
            throw new ArgumentException(); 
        }

        // This is optional
        if (inputStream.CanSeek)
        {
            inputStream.Seek(0, SeekOrigin.Begin);
        }

        byte[] output = new byte[inputStream.Length];
        int bytesRead = inputStream.Read(output, 0, output.Length);
        Debug.Assert(bytesRead == output.Length, "Bytes read from stream matches stream length");
        return output;
    }

Test:

    static void Main(string[] args)
    {
        byte[] data;
        string path = @"C:\Windows\System32\notepad.exe";
        using (FileStream fs = File.Open(path, FileMode.Open, FileAccess.Read))
        {
            data = StreamToByteArray(fs);
        }

        Debug.Assert(data.Length > 0);
        Debug.Assert(new FileInfo(path).Length == data.Length); 
    }

I would ask, why do you want to read a stream into a byte[], if you are wishing to copy the contents of a stream, may I suggest using MemoryStream and writing your input stream into a memory stream.

for me it worked the approach that I used in eclipselink as well. Just call the size() of the collection that should be loaded before using it as parameter to pages.

for (Entity e : entityListKeeper.getEntityList()) {
    e.getListLazyLoadedEntity().size();
}

Here entityListKeeper has List of Entity that has list of LazyLoadedEntity. If you have just therelation Entity has list of LazyLoadedEntity then the solution is:

getListLazyLoadedEntity().size();

Open a new worksheet on the related instance (Alt-F10) and run the following query

SELECT view_name, owner
FROM sys.all_views 
ORDER BY owner, view_name

Use np.mat(x) * np.mat(y), that'll work.

You need to use anaconda to manage python environment dependencies. MySQL connector can be installed using conda installer

conda install -c anaconda mysql-connector-python

This worked for me :

select option {
   color: black;
}
select:not(:checked) {
   color: gray;
}

There is no way to explicitly specify the template arguments when calling a constructor template, so they have to be deduced through argument deduction. This is because if you say:

Foo<int> f = Foo<int>();

The <int> is the template argument list for the type Foo, not for its constructor. There's nowhere for the constructor template's argument list to go.

Even with your workaround you still have to pass an argument in order to call that constructor template. It's not at all clear what you are trying to achieve.

Pay attention, if you use cv.CV_THRESH_BINARY means every pixel greater than threshold becomes the maxValue (in your case 255), otherwise the value is 0. Obviously if your threshold is 0 everything becomes white (maxValue = 255) and if the value is 255 everything becomes black (i.e. 0).

If you don't want to work out a threshold, you can use the Otsu's method. But this algorithm only works with 8bit images in the implementation of OpenCV. If your image is 8bit use the algorithm like this:

cv.Threshold(im_gray_mat, im_bw_mat, threshold, 255, cv.CV_THRESH_BINARY | cv.CV_THRESH_OTSU);

No matter the value of threshold if you have a 8bit image.

Use this:

List<Class1> myList;
ObservableCollection<Class1> myOC = new ObservableCollection<Class1>(myList);

In very laymen terms the class is a mold and the object is the copy made with that mold. Static belong to the mold and can be accessed directly without making any copies, hence the example above

Follow the steps to store data in Angular - local storage:

1. Add 'ngStorage.js' in your folder.

2. Inject 'ngStorage' in your angular.module

       eg: angular.module("app", [ 'ngStorage']);
   

3. Add $localStorage in your app.controller function

4.You can use $localStorage inside your controller

Eg: $localstorage.login= true;

The above will store the localstorage in your browser application

I ran into the same issue and had the right API level values in my build.gradle compileSdkVersion 21, targetSdkVersion 21 and a buildToolsVersion of 21.0.1

However, I was including this as a module in my project so I had to make sure the other module gradle settings matched API 21. After that it all worked for me.

Use PHP Document Object Model:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   $DOM = new DOMDocument;
   $DOM->loadHTML($str);

   //get all H1
   $items = $DOM->getElementsByTagName('h1');

   //display all H1 text
   for ($i = 0; $i < $items->length; $i++)
        echo $items->item($i)->nodeValue . "<br/>";
?>

This outputs as:

 T1
 T2
 T3

[EDIT]: After OP Clarification:

If you want the content like Lorem ipsum. etc, you can directly use this regex:

<?php
   $str = '<h1>T1</h1>Lorem ipsum.<h1>T2</h1>The quick red fox...<h1>T3</h1>... jumps over the lazy brown FROG';
   echo preg_replace("#<h1.*?>.*?</h1>#", "", $str);
?>

this outputs:

Lorem ipsum.The quick red fox...... jumps over the lazy brown FROG

The following query will select all of the Tables in the database named DBName:

USE DBName
GO 
SELECT *
FROM sys.Tables
GO

I think this is pretty obvious :

• $observe is used in linking function of directives.
• $watch is used on scope to watch any changing in its values.

Keep in mind : both the function has two arguments,

$observe/$watch(value : string, callback : function);

• value : is always a string reference to the watched element (the name of a scope's variable or the name of the directive's attribute to be watched)
• callback : the function to be executed of the form function (oldValue, newValue)

I have made a plunker, so you can actually get a grasp on both their utilization. I have used the Chameleon analogy as to make it easier to picture.

Solution April 2020:

So the above answers are cute but they all have (imo) a big flaw: they are calculating the height of the image, based on the width of the user's device.

To have a truly responsive (i.e. width: 100%, height: auto) implementation, what you really want to be doing, is calculating the height of the image, based on the width of the parent container.

Luckily for us, React Native provides us with a way to get the parent container width, thanks to the onLayout View method.

So all we need to do is create a View with width: "100%", then use onLayout to get the width of that view (i.e. the container width), then use that container width to calculate the height of our image appropriately.

Just show me the code...

The below solution could be improved upon further, by using RN's Image.getSize, to grab the image dimensions within the ResponsiveImage component itself.

JavaScript:

// ResponsiveImage.ts

import React, { useMemo, useState } from "react";
import { Image, StyleSheet, View } from "react-native";

const ResponsiveImage = props => {
  const [containerWidth, setContainerWidth] = useState(0);
  const _onViewLayoutChange = event => {
    const { width } = event.nativeEvent.layout;
    setContainerWidth(width);
  }

  const imageStyles = useMemo(() => {
    const ratio = containerWidth / props.srcWidth;
    return {
      width: containerWidth,
      height: props.srcHeight * ratio
    };
  }, [containerWidth]);

  return (
    <View style={styles.container} onLayout={_onViewLayoutChange}>
      <Image source={props.src} style={imageStyles} />
    </View>
  );
};

const styles = StyleSheet.create({
  container: { width: "100%" }
});

export default ResponsiveImage;


// Example usage...

import ResponsiveImage from "../components/ResponsiveImage";

...

<ResponsiveImage
  src={require("./images/your-image.jpg")}
  srcWidth={910} // replace with your image width
  srcHeight={628} // replace with your image height
/>

TypeScript:

// ResponsiveImage.ts

import React, { useMemo, useState } from "react";
import {
  Image,
  ImageSourcePropType,
  LayoutChangeEvent,
  StyleSheet,
  View
} from "react-native";

interface ResponsiveImageProps {
  src: ImageSourcePropType;
  srcWidth: number;
  srcHeight: number;
}

const ResponsiveImage: React.FC<ResponsiveImageProps> = props => {
  const [containerWidth, setContainerWidth] = useState<number>(0);
  const _onViewLayoutChange = (event: LayoutChangeEvent) => {
    const { width } = event.nativeEvent.layout;
    setContainerWidth(width);
  }

  const imageStyles = useMemo(() => {
    const ratio = containerWidth / props.srcWidth;
    return {
      width: containerWidth,
      height: props.srcHeight * ratio
    };
  }, [containerWidth]);

  return (
    <View style={styles.container} onLayout={_onViewLayoutChange}>
      <Image source={props.src} style={imageStyles} />
    </View>
  );
};

const styles = StyleSheet.create({
  container: { width: "100%" }
});

export default ResponsiveImage;


// Example usage...

import ResponsiveImage from "../components/ResponsiveImage";

...

<ResponsiveImage
  src={require("./images/your-image.jpg")}
  srcWidth={910} // replace with your image width
  srcHeight={628} // replace with your image height
/>

It help to reduce lot of codes. It is occasionally used in RGB values which consist of 8bits.

where 0xff means 24(0's ) and 8(1's) like 00000000 00000000 00000000 11111111

It effectively masks the variable so it leaves only the value in the last 8 bits, and ignores all the rest of the bits

It’s seen most in cases like when trying to transform color values from a special format to standard RGB values (which is 8 bits long).

Great Explanation See here

If you don't want to use a map, then just follow these steps:

1. Sort the array (using Arrays.sort())
2. Use a variable to hold the most popular element (mostPopular), a variable to hold its number of occurrences in the array (mostPopularCount), and a variable to hold the number of occurrences of the current number in the iteration (currentCount)
3. Iterate through the array. If the current element is the same as mostPopular, increment currentCount. If not, reset currentCount to 1. If currentCount is > mostPopularCount, set mostPopularCount to currentCount, and mostPopular to the current element.

Microsoft SQL Server 2005 Express Edition Service Pack 4 on Windows Server 2012 R2

Those steps are based on previous howto from https://stackoverflow.com/users/2385/eduardo-molteni

1. download SQLEXPR.EXE
2. run SQLEXPR.EXE
3. copy c:\generated_installation_dir to inst.bak
4. quit install
5. run inst.bak/setuip/sqlncli_x64.msi
6. run SQLEXPR.EXE
7. enjoy!

If you don't specify any path and put just the file (Just like you did), the default directory is always the one of your project (It's not inside the "src" folder. It's just inside the folder of your project).

You can do it by using attr, the mistake that you made is that you put the true inside quotes. instead of that try this:

$("input").attr("required", true);

Set the opacity of its view it is showed in.

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageWithName:@"SomeName.png"]];
imageView.alpha = 0.5; //Alpha runs from 0.0 to 1.0

Use this in an animation. You can change the alpha in an animation for an duration.

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
//Set alpha
[UIView commitAnimations];

color and fill are separate aesthetics. Since you want to modify the color you need to use the corresponding scale:

d + scale_color_manual(values=c("#CC6666", "#9999CC"))

is what you want.

Due to PermGen removal some options were removed (like -XX:MaxPermSize), but options -Xms and -Xmx work in Java 8. It's possible that under Java 8 your application simply needs somewhat more memory. Try to increase -Xmx value. Alternatively you can try to switch to G1 garbage collector using -XX:+UseG1GC.

Note that if you use any option which was removed in Java 8, you will see a warning upon application start:

$ java -XX:MaxPermSize=128M -version
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128M; support was removed in 8.0

Fixing the seed is essential when we try to optimize a function that involves randomly generated numbers (e.g. in simulation based estimation). Loosely speaking, if we do not fix the seed, the variation due to drawing different random numbers will likely cause the optimization algorithm to fail.

Suppose that, for some reason, you want to estimate the standard deviation (sd) of a mean-zero normal distribution by simulation, given a sample. This can be achieved by running a numerical optimization around steps

1. (Setting the seed)
2. Given a value for sd, generate normally distributed data
3. Evaluate the likelihood of your data given the simulated distributions

The following functions do this, once without step 1., once including it:

# without fixing the seed
simllh <- function(sd, y, Ns){
  simdist <- density(rnorm(Ns, mean = 0, sd = sd))
  llh <- sapply(y, function(x){ simdist$y[which.min((x - simdist$x)^2)] })
  return(-sum(log(llh)))
}
# same function with fixed seed
simllh.fix.seed <- function(sd,y,Ns){
  set.seed(48)
  simdist <- density(rnorm(Ns,mean=0,sd=sd))
  llh <- sapply(y,function(x){simdist$y[which.min((x-simdist$x)^2)]})
  return(-sum(log(llh)))
}

We can check the relative performance of the two functions in discovering the true parameter value with a short Monte Carlo study:

N <- 20; sd <- 2 # features of simulated data
est1 <- rep(NA,1000); est2 <- rep(NA,1000) # initialize the estimate stores
for (i in 1:1000) {
  as.numeric(Sys.time())-> t; set.seed((t - floor(t)) * 1e8 -> seed) # set the seed to random seed
  y <- rnorm(N, sd = sd) # generate the data
  est1[i] <- optim(1, simllh, y = y, Ns = 1000, lower = 0.01)$par
  est2[i] <- optim(1, simllh.fix.seed, y = y, Ns = 1000, lower = 0.01)$par
}
hist(est1)
hist(est2)

The resulting distributions of the parameter estimates are:

When we fix the seed, the numerical search ends up close to the true parameter value of 2 far more often.

There is yet an another way to add interceptors in your OkHttp3 (latest version as of now) , that is you add the interceptors to your Okhttp builder

okhttpBuilder.networkInterceptors().add(chain -> {
 //todo add headers etc to your AuthorisedRequest

  return chain.proceed(yourAuthorisedRequest);
});

and finally build your okHttpClient from this builder

OkHttpClient client = builder.build();

Even both eacceleator and xcache perform quite well during moderate loads, APC maintains its stability under serious request intensity. If we're talking about a few hundred requests/sec here, you'll not feel the difference. But if you're trying to respond more, definetely stick with APC. Especially if your application has overly dynamic characteristics which will likely cause locking issues under such loads. http://www.ipsure.com/blog/2011/eaccelerator-as-zend-extension-high-load-averages-issue/ may help.

wrap your entire code block in this:

//<![CDATA[

//code here

//]]>

also make sure to specify the type of script to be text/javascript

try that and let me know how it goes

There's no need to both strip and chomp as strip will also remove trailing carriage returns - unless you've changed the default record separator and that's what you're chomping.

Olly's answer already has the canonical way of doing this in Ruby, though if you find yourself doing this a lot you could always define a method for it:

def strip_or_self!(str)
  str.strip! || str
end

Giving:

@title = strip_or_self!(tokens[Title]) if tokens[Title]

Also keep in mind that the if statement will prevent @title from being assigned if the token is nil, which will result in it keeping its previous value. If you want or don't mind @title always being assigned you can move the check into the method and further reduce duplication:

def strip_or_self!(str)
  str.strip! || str if str
end

As an alternative, if you're feeling adventurous you can define a method on String itself:

class String
  def strip_or_self!
    strip! || self
  end
end

Giving one of:

@title = tokens[Title].strip_or_self! if tokens[Title]

@title = tokens[Title] && tokens[Title].strip_or_self!

I'd like to suggest another approach to the "Oups I forgot to write sudo while opening my file" issue:

Instead of receiving a permission denied, and having to type :w!!, I find it more elegant to have a conditional vim command that does sudo vim if file owner is root.

This is as easy to implement (there might even be more elegant implementations, I'm clearly not a bash-guru):

function vim(){
  OWNER=$(stat -c '%U' $1)
  if [[ "$OWNER" == "root" ]]; then
    sudo /usr/bin/vim $*;
  else
    /usr/bin/vim $*;
  fi
}

And it works really well.

This is a more bash-centered approach than a vim-one so not everybody might like it.

Of course:

• there are use cases where it will fail (when file owner is not root but requires sudo, but the function can be edited anyway)
• it doesn't make sense when using vim for reading-only a file (as far as I'm concerned, I use tail or cat for small files)

But I find this brings a much better dev user experience, which is something that IMHO tends to be forgotten when using bash. :-)

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()
