Use

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });

It may be possible (but very hackish) with only CSS using the :before or :after pseudo elements:

.bgtext {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
.bgtext:after {_x000D_
  content: "Background text";_x000D_
  position: absolute;_x000D_
  top: 0;_x000D_
  left: 0;_x000D_
  z-index: -1;_x000D_
}

<div class="bgtext">_x000D_
  Foreground text_x000D_
</div>

This seems to work, but you'll probably need to tweak it a little. Also note it won't work in IE6 because it doesn't support :after.

Managed Code

Managed code is what Visual Basic .NET and C# compilers create. It runs on the CLR (Common Language Runtime), which, among other things, offers services like garbage collection, run-time type checking, and reference checking. So, think of it as, "My code is managed by the CLR."

Visual Basic and C# can only produce managed code, so, if you're writing an application in one of those languages you are writing an application managed by the CLR. If you are writing an application in Visual C++ .NET you can produce managed code if you like, but it's optional.

Unmanaged Code

Unmanaged code compiles straight to machine code. So, by that definition all code compiled by traditional C/C++ compilers is 'unmanaged code'. Also, since it compiles to machine code and not an intermediate language it is non-portable.

No free memory management or anything else the CLR provides.

Since you cannot create unmanaged code with Visual Basic or C#, in Visual Studio all unmanaged code is written in C/C++.

Mixing the two

Since Visual C++ can be compiled to either managed or unmanaged code it is possible to mix the two in the same application. This blurs the line between the two and complicates the definition, but it's worth mentioning just so you know that you can still have memory leaks if, for example, you're using a third party library with some badly written unmanaged code.

Here's an example I found by googling:

#using <mscorlib.dll>
using namespace System;

#include "stdio.h"

void ManagedFunction()
{
    printf("Hello, I'm managed in this section\n");
}

#pragma unmanaged
UnmanagedFunction()
{
    printf("Hello, I am unmanaged through the wonder of IJW!\n");
    ManagedFunction();
}

#pragma managed
int main()
{
    UnmanagedFunction();
    return 0;
}

must please see guys that the error is in the cv2.imread() .Give the right path of the image. and firstly, see if your system loads the image or not. this can be checked first by simple load of image using cv2.imread(). after that ,see this code for the face detection

import numpy as np
import cv2

cascPath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-   packages/cv2/data/haarcascade_frontalface_default.xml"

eyePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_eye.xml"

smilePath = "/Users/mayurgupta/opt/anaconda3/lib/python3.7/site-packages/cv2/data/haarcascade_smile.xml"

face_cascade = cv2.CascadeClassifier(cascPath)
eye_cascade = cv2.CascadeClassifier(eyePath)
smile_cascade = cv2.CascadeClassifier(smilePath)

img = cv2.imread('WhatsApp Image 2020-04-04 at 8.43.18 PM.jpeg')
gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

faces = face_cascade.detectMultiScale(gray, 1.3, 5)
for (x,y,w,h) in faces:
    img = cv2.rectangle(img,(x,y),(x+w,y+h),(255,0,0),2)
    roi_gray = gray[y:y+h, x:x+w]
    roi_color = img[y:y+h, x:x+w]
    eyes = eye_cascade.detectMultiScale(roi_gray)
    for (ex,ey,ew,eh) in eyes:
        cv2.rectangle(roi_color,(ex,ey),(ex+ew,ey+eh),(0,255,0),2)

cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()

Here, cascPath ,eyePath ,smilePath should have the right actual path that's picked up from lib/python3.7/site-packages/cv2/data here this path should be to picked up the haarcascade files

  public Optional<String> InputStreamToBase64(Optional<InputStream> inputStream) throws IOException{
    if (inputStream.isPresent()) {
        ByteArrayOutputStream outpString base64Image = data.split(",")[1];
byte[] imageBytes = javax.xml.bind.DatatypeConverter.parseBase64Binary(base64Image);

Then you can do whatever you like with the bytes like:

BufferedImage img = ImageIO.read(new ByteArrayInputStream(imageBytes));ut = new ByteArrayOutputStream();
        FileCopyUtils.copy(inputStream.get(), output);
        //TODO retrieve content type from file, & replace png below with it
        return Optional.ofNullable("data:image/png;base64," + DatatypeConverter.printBase64Binary(output.toByteArray()));
    }

    return Optional.empty();

I was also looking for this answer until I came across this post.

I've found another solution to know the keycode of the different keys, courtesy to my problem. I just wanted to share my solution.

Just use keyup/keydown event to write the value in the console/alert the same using event.keyCode. like-

console.log(event.keyCode) 

// or

alert(event.keyCode)

Just to augment the other answers from a different angle.

If you want to reuse hashcode(s) from 'above' and derive new ones using your class' immutatable state, then a call to super will work. While this may/may not cascade all the way up to Object (i.e. some ancestor may not call super), it will allow you to derive hashcodes by reuse.

@Override
public int hashCode() {
    int ancestorHash = super.hashCode();
    // now derive new hash from ancestorHash plus immutable instance vars (id fields)
}

Try this: Stretchy Sprites - Cross-browser, responsive resizing/stretching of CSS sprite images

This method scales sprites 'responsively' so that the width/height adjust according to your browser window size. It doesn't use background-size as support for this in older browsers is non-existent.

CSS

.stretchy {display:block; float:left; position:relative; overflow:hidden; max-width:160px;}
.stretchy .spacer {width: 100%; height: auto;}
.stretchy .sprite {position:absolute; top:0; left:0; max-width:none; max-height:100%;}
.stretchy .sprite.s2 {left:-100%;}
.stretchy .sprite.s3 {left:-200%;}

HTML

<a class="stretchy" href="#">
  <img class="spacer" alt="" src="spacer.png">
  <img class="sprite" alt="icon" src="sprite_800x160.jpg">
</a>
<a class="stretchy s2" href="#">
  <img class="spacer" alt="" src="spacer.png">
  <img class="sprite" alt="icon" src="sprite_800x160.jpg">
</a>
<a class="stretchy s3" href="#">

You can implement routerOnActivate() method on your route class, it will provide information about previous route.

routerOnActivate(nextInstruction: ComponentInstruction, prevInstruction: ComponentInstruction) : any

Then you can use router.navigateByUrl() and pass data generated from ComponentInstruction. For example:

this._router.navigateByUrl(prevInstruction.urlPath);

Don't fret too much if your initial API is fully RESTful or not (specially when you are just in the alpha stages). Get the back-end plumbing to work first. You can always do some sort of URL transformation/re-writing to map things out, refining iteratively until you get something stable enough for widespread testing ("beta").

You can define URIs whose parameters are encoded by position and convention on the URIs themselves, prefixed by a path you know you'll always map to something. I don't know PHP, but I would assume that such a facility exists (as it exists in other languages with web frameworks):

.ie. Do a "user" type of search with param[i]=value[i] for i=1..4 on store #1 (with value1,value2,value3,... as a shorthand for URI query parameters):

1) GET /store1/search/user/value1,value2,value3,value4

or

2) GET /store1/search/user,value1,value2,value3,value4

or as follows (though I would not recommend it, more on that later)

3) GET /search/store1,user,value1,value2,value3,value4

With option 1, you map all URIs prefixed with /store1/search/user to the search handler (or whichever the PHP designation) defaulting to do searches for resources under store1 (equivalent to /search?location=store1&type=user.

By convention documented and enforced by the API, parameters values 1 through 4 are separated by commas and presented in that order.

Option 2 adds the search type (in this case user) as positional parameter #1. Either option is just a cosmetic choice.

Option 3 is also possible, but I don't think I would like it. I think the ability of search within certain resources should be presented in the URI itself preceding the search itself (as if indicating clearly in the URI that the search is specific within the resource.)

The advantage of this over passing parameters on the URI is that the search is part of the URI (thus treating a search as a resource, a resource whose contents can - and will - change over time.) The disadvantage is that parameter order is mandatory.

Once you do something like this, you can use GET, and it would be a read-only resource (since you can't POST or PUT to it - it gets updated when it's GET'ed). It would also be a resource that only comes to exist when it is invoked.

One could also add more semantics to it by caching the results for a period of time or with a DELETE causing the cache to be deleted. This, however, might run counter to what people typically use DELETE for (and because people typically control caching with caching headers.)

How you go about it would be a design decision, but this would be the way I'd go about. It is not perfect, and I'm sure there will be cases where doing this is not the best thing to do (specially for very complex search criteria).

The code you're using is also going to include a fadeout effect. Is this what you want to achieve? If not, it might make more sense to just add the following INSIDE "Small.php".

<meta http-equiv="refresh" content="15" >

This adds a refresh every 15seconds to the small.php page which should mean if called by PHP into another page, only that "frame" will reload.

Let us know if it worked/solved your problem!?

For SQL Server 2005 and above use Coalesce for nulls and I am using Cast or Convert if there are numeric values -

declare @CodeNameString  nvarchar(max)
select  @CodeNameString = COALESCE(@CodeNameString + ',', '')  + Cast(CodeName as varchar) from AccountCodes  ORDER BY Sort
select  @CodeNameString

FOR SQL SERVER

IF EXISTS(select * FROM sys.views where name = '')

Column(
  children: <Widget>[
    FirstWidget(),
    Spacer(),
    SecondWidget(),
  ]
)

Spacer creates a flexible space to insert into a [Flexible] widget. (Like a column)

In case you're inside an ng-repeat

you could use a one liner option

    <div ng-repeat="key in keywords"> 
        <button ng-click="keywords.splice($index, 1)">

            {{key.name}}
        </button>
    </div>

$index is used by angular to show current index of the array inside ng-repeat

The models.CharField is a CharField representation of one of the choices. What you want is a set of choices. This doesn't seem to be implemented in django (yet).

You could use a many to many field for it, but that has the disadvantage that the choices have to be put in a database. If you want to use hard coded choices, this is probably not what you want.

There is a django snippet at http://djangosnippets.org/snippets/1200/ that does seem to solve your problem, by implementing a ModelField MultipleChoiceField.

Just a quick follow up and note that it is possible now to use the support library with weighted spacing in GridLayout to achieve what you want, see:

As of API 21, GridLayout's distribution of excess space accomodates the principle of weight. In the event that no weights are specified, the previous conventions are respected and columns and rows are taken as flexible if their views specify some form of alignment within their groups. The flexibility of a view is therefore influenced by its alignment which is, in turn, typically defined by setting the gravity property of the child's layout parameters. If either a weight or alignment were defined along a given axis then the component is taken as flexible in that direction. If no weight or alignment was set, the component is instead assumed to be inflexible.

Very simple, no library required:

var date = new Date();
var firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
var lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

or you might prefer:

var date = new Date(), y = date.getFullYear(), m = date.getMonth();
var firstDay = new Date(y, m, 1);
var lastDay = new Date(y, m + 1, 0);

EDIT

Some browsers will treat two digit years as being in the 20th century, so that:

new Date(14, 0, 1);

gives 1 January, 1914. To avoid that, create a Date then set its values using setFullYear:

var date = new Date();
date.setFullYear(14, 0, 1); // 1 January, 14

Try a custom propTypes :

 const  childrenPropTypeLogic = (props, propName, componentName) => {
          const prop = props[propName];
          return React.Children
                   .toArray(prop)
                   .find(child => child.type !== 'div') && new Error(`${componentName} only accepts "div" elements`);
 };


static propTypes = {

   children : childrenPropTypeLogic

}

JSPs are the View component of MVC (Model View Controller). The Controller takes the incoming request and passes it to the Model, which might be a bean that does some database access. The JSP then formats the output using HTML, CSS and JavaScript, and the output then gets sent back to the requester.

You can try this.

protected $rules_update = [
    'email_address' => 'required|email|unique:users,email_address,'. $this->id,
    'first_name' => "required",
    'last_name' => "required",
    'password' => "required|min:6|same:password_confirm",
    'password_confirm' => "required:min:6|same:password",
    'password_current' => "required:min:6"
];

Try this:

$log = $this->Model->getDataSource()->getLog(false, false);
debug($log);

http://api.cakephp.org/2.3/class-Model.html#_getDataSource

You will have to do this for each datasource if you have more than one though.

I still prefer the method in one line

new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(Calendar.getInstance().getTime())

In Swift, using xcode 7 (and later), you can add the following to your AppDelegate.swift file:

UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)

This is the what the complete method looks like:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    // I added this line
    UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)

    return true
}

In the example above my item will be white. The "/255.0" is needed because it expects a value from 0 to 1. For white, I could have just used 1. But for other color you'll probably be using RGB values.

You are close already. Just make sure to hide the checkbox and associate it with a label you style via input[checkbox] + label

Given that what you want is to determine the full id of the element based upon just the prefix, you're going to have to do a search of the entire DOM (or at least, a search of an entire subtree if you know of some element that is always guaranteed to contain your target element). You can do this with something like:

function findChildWithIdLike(node, prefix) {
    if (node && node.id && node.id.indexOf(prefix) == 0) {
        //match found
        return node;
    }

    //no match, check child nodes
    for (var index = 0; index < node.childNodes.length; index++) {
        var child = node.childNodes[index];
        var childResult = findChildWithIdLike(child, prefix);
        if (childResult) {
            return childResult;
        }
    }
};

Here is an example: http://jsfiddle.net/xwqKh/

Be aware that dynamic element ids like the ones you are working with are typically used to guarantee uniqueness of element ids on a single page. Meaning that it is likely that there are multiple elements that share the same prefix. Probably you want to find them all.

If you want to find all of the elements that have a given prefix, instead of just the first one, you can use something like what is demonstrated here: http://jsfiddle.net/xwqKh/1/

Add some inline css to the anchor tag

<li><a style = "color:blue" href="#"><span class="glyphicon glyphicon-user"></span> About</a></li>

This should add the color blue to the anchor tag text.

Short answer: yes you can. Of course you'll have to make sure that the new value doesn't match any existing value and other constraints are satisfied (duh).

What exactly are you trying to do?

In general it's a pain to write a regular expression not containing a particular string. We had to do this for models of computation - you take an NFA, which is easy enough to define, and then reduce it to a regular expression. The expression for things not containing "cat" was about 80 characters long.

Edit: I just finished and yes, it's:

aa([^a] | a[^a])aa

Here is a very brief tutorial. I found some great ones before, but I can't see them anymore.

If you're doing much numerical work with arrays like this, I'd suggest numpy, which comes with a cumulative sum function cumsum:

import numpy as np

a = [4,6,12]

np.cumsum(a)
#array([4, 10, 22])

Numpy is often faster than pure python for this kind of thing, see in comparison to @Ashwini's accumu:

In [136]: timeit list(accumu(range(1000)))
10000 loops, best of 3: 161 us per loop

In [137]: timeit list(accumu(xrange(1000)))
10000 loops, best of 3: 147 us per loop

In [138]: timeit np.cumsum(np.arange(1000))
100000 loops, best of 3: 10.1 us per loop

But of course if it's the only place you'll use numpy, it might not be worth having a dependence on it.

If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;

wget --no-verbose --no-parent --recursive --level=1\
--no-directories --user=login --password=pass ftp://ftp.myftpsite.com/

• --no-parent : Do not ever ascend to the parent directory when retrieving recursively.
• --level=depth : Specify recursion maximum depth level depth. The default maximum depth is five layers.
• --no-directories : Do not create a hierarchy of directories when retrieving recursively.

Just to complete, you could send 3 arguments like this:

objShell.Run "TestScript.vbs 42 ""an arg containing spaces"" foo" 

I have to offer this as a better approach - you don't always have the luxury of an identity field:

UPDATE m
SET [status]=10
FROM (
  Select TOP (10) *
  FROM messages
  WHERE [status]=0
  ORDER BY [priority] DESC
) m

You can also make the sub-query as complicated as you want - joining multiple tables, etc...

Why is this better? It does not rely on the presence of an identity field (or any other unique column) in the messages table. It can be used to update the top N rows from any table, even if that table has no unique key at all.

MS SQL Server 2008 introduces the MERGE statement, which I believe is part of the SQL:2003 standard. As many have shown it is not a big deal to handle one row cases, but when dealing with large datasets, one needs a cursor, with all the performance problems that come along. The MERGE statement will be much welcomed addition when dealing with large datasets.

In my case, it was due to an IP address that Apache is listening to. Previously I have set it to 192.168.10.6 and recently Apache service is not running. I noticed that due to My laptop wifi changed recently and new IP is different. After fixing the wifi IP to laptop previous IP, Apache service is running again without any error.

Also if you don't want to change wifi IP then remove/comment that hardcode IP in httpd.conf file to resolve conflict.

Note: This retrieves the "Phone number" that was entered during the iPhone's iTunes activation and can be null or an incorrect value. It's NOT read from the SIM card.

At least that does in 2.1. There are a couple of other interesting keys in NSUserDefaults that may also not last. (This is in my app which uses a UIWebView)

UPDATE:

Modified the code based on this answer to get rid of obsolete methods.

You can use the Security namespace to check this:

public void ExportToFile(string filename)
{
    var permissionSet = new PermissionSet(PermissionState.None);    
    var writePermission = new FileIOPermission(FileIOPermissionAccess.Write, filename);
    permissionSet.AddPermission(writePermission);

    if (permissionSet.IsSubsetOf(AppDomain.CurrentDomain.PermissionSet))
    {
        using (FileStream fstream = new FileStream(filename, FileMode.Create))
        using (TextWriter writer = new StreamWriter(fstream))
        {
            // try catch block for write permissions 
            writer.WriteLine("sometext");


        }
    }
    else
    {
        //perform some recovery action here
    }

}

As far as getting those permission, you are going to have to ask the user to do that for you somehow. If you could programatically do this, then we would all be in trouble ;)

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top;

            scrollTop: top
        }, 100);
    });
}

if you want to scroll a little above or below from specific div that add value to the top like this.....like I add 800

var top = ($(".apps_intro_wrapper_inner").offset() || { "top": NaN }).top + 800;

Here's a one liner:

val => ['Bytes','Kb','Mb','Gb','Tb'][Math.floor(Math.log2(val)/10)]

Or even:

Whilst the above answers are correct its worth noting that MSBuild has changed and it no longer ships with the .net framework, it comes either stand alone or with visual studio. As a result it's binaries have moved... so the one you get under the 4.0.303619 directory is actually the old one!

I've just been caught out by this - I found automatic binding redirects were only working when running from VisualStudio but not when running msbuild from the command line... the clue was that binding redirects were added in VS 2013 (for that read .net framework 4.5). If you open up a vs command prompt you'll see it now gets it from program files as the other article mentions. Whereas I was using a batch file on my path which linked to the old version.

Calling setOpaque(false) on the upper JPanel should work.

From your comment, it sounds like Swing painting may be broken somewhere -

First - you probably wanted to override paintComponent() rather than paint() in whatever component you have paint() overridden in.

Second - when you do override paintComponent(), you'll first want to call super.paintComponent() first to do all the default Swing painting stuff (of which honoring setOpaque() is one).

Example -

import java.awt.Color;
import java.awt.Graphics;

import javax.swing.JFrame;
import javax.swing.JPanel;


public class TwoPanels {
    public static void main(String[] args) {

        JPanel p = new JPanel();
        // setting layout to null so we can make panels overlap
        p.setLayout(null);

        CirclePanel topPanel = new CirclePanel();
        // drawing should be in blue
        topPanel.setForeground(Color.blue);
        // background should be black, except it's not opaque, so 
        // background will not be drawn
        topPanel.setBackground(Color.black);
        // set opaque to false - background not drawn
        topPanel.setOpaque(false);
        topPanel.setBounds(50, 50, 100, 100);
        // add topPanel - components paint in order added, 
        // so add topPanel first
        p.add(topPanel);

        CirclePanel bottomPanel = new CirclePanel();
        // drawing in green
        bottomPanel.setForeground(Color.green);
        // background in cyan
        bottomPanel.setBackground(Color.cyan);
        // and it will show this time, because opaque is true
        bottomPanel.setOpaque(true);
        bottomPanel.setBounds(30, 30, 100, 100);
        // add bottomPanel last...
        p.add(bottomPanel);

        // frame handling code...
        JFrame f = new JFrame("Two Panels");
        f.setContentPane(p);
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.setSize(300, 300);
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    // Panel with a circle drawn on it.
    private static class CirclePanel extends JPanel {

        // This is Swing, so override paint*Component* - not paint
        protected void paintComponent(Graphics g) {
            // call super.paintComponent to get default Swing 
            // painting behavior (opaque honored, etc.)
            super.paintComponent(g);
            int x = 10;
            int y = 10;
            int width = getWidth() - 20;
            int height = getHeight() - 20;
            g.drawArc(x, y, width, height, 0, 360);
        }
    }
}

This Will work in Spring boot 2.0.3+ and Jackson 2.0+

import com.fasterxml.jackson.annotation.JsonInclude;

@JsonInclude(JsonInclude.Include.NON_NULL)
public class ApiDTO
{
    // your class variable and 
    // methods
}

Depending on what you're actually going to do with the data after it's collected, collections.defaultdict(int) might be useful.

The short answer: no.

The long answer:

Fixed formats work better for HTML emails. In my experience you're best off pretending it's 1999 when it comes to HTML emails. Be explicit and use HTML attributes (width="650") where ever possible in your table definitions, not CSS (style="width:650px"). Use fixed widths, no percentages. A table width of 650 pixels wide is a safe bet. Use inline CSS to set text properties.

It's not a matter of what works in "HTML emails", but rather the plethora of email clients and their limited (and sometimes deliberately so in the case of Gmail, Hotmail etc) ability to render HTML.

For a set of images (each image has 3 dimensions), where I wanted to reject outliers for each pixel I used:

mean = np.mean(imgs, axis=0)
std = np.std(imgs, axis=0)
mask = np.greater(0.5 * std + 1, np.abs(imgs - mean))
masked = np.multiply(imgs, mask)

Then it is possible to compute the mean:

masked_mean = np.divide(np.sum(masked, axis=0), np.sum(mask, axis=0))

(I use it for Background Subtraction)

Use the basename method of the path module:

path.basename('/foo/bar/baz/asdf/quux.html')
// returns
'quux.html'

Here is the documentation the above example is taken from.

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.

Just type the code and save it in .cpp format. then try "gcc filename.cpp" . This will create the object file. then try "./a.out" (This is the default object file name). If you want to know about gcc you can always try "man gcc"

This solved the same error for me on Debian:

sudo apt-get install libffi-dev

and compile again

Reference: issue31652

There is an important bit that is not mentioned in the article to which you linked and that is flex-basis. By default flex-basis is auto.

From the spec:

If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)

Each flex item has a flex-basis which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow) among the items. With auto, that basis is the contents size (or defined size with width, etc.). As a result, items with bigger text within are being given more space overall in your example.

If you want your elements to be completely even, you can set flex-basis: 0. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow.

li {
    flex-grow: 1;
    flex-basis: 0;
    /* ... */
}

This diagram from the spec does a pretty good job of illustrating the point.

And here is a working example with your fiddle.

Your Call works if it were a Table Valued Function. Since its a scalar function, you need to call it like:

SELECT dbo.fn_HomePageSlider(9, 3025) AS MyResult

var FD = new System.Windows.Forms.OpenFileDialog();
if (FD.ShowDialog() == System.Windows.Forms.DialogResult.OK) {
    string fileToOpen = FD.FileName;

    System.IO.FileInfo File = new System.IO.FileInfo(FD.FileName);

    //OR

    System.IO.StreamReader reader = new System.IO.StreamReader(fileToOpen);
    //etc
}

FILE *fp;
char* str = "string";
int x = 10;

fp=fopen("test.txt", "w");
if(fp == NULL)
    exit(-1);
fprintf(fp, "This is a string which is written to a file\n");
fprintf(fp, "The string has %d words and keyword %s\n", x, str);
fclose(fp);

Use SHOW VARIABLES:

show variables like 'version';

Not every List implementation supports the add() method.

One common example is the List returned by Arrays.asList(): it is documented not to support any structural modification (i.e. removing or adding elements) (emphasis mine):

Returns a fixed-size list backed by the specified array.

Even if that's not the specific List you're trying to modify, the answer still applies to other List implementations that are either immutable or only allow some selected changes.

You can find out about this by reading the documentation of UnsupportedOperationException and List.add(), which documents this to be an "(optional operation)". The precise meaning of this phrase is explained at the top of the List documentation.

As a workaround you can create a copy of the list to a known-modifiable implementation like ArrayList:

seeAlso = new ArrayList<>(seeAlso);

No, that's not how it is done. Normal way to initialize the base class is in the initialization list :

class A
{
public: 
    A(int val) {}
};

class B : public A
{
public:
  B( int v) : A( v )
  {
  }
};


void main()
{
    B b(10);
}

Two possibilities here. Java Version incompatible or import

Call next function like

byte[] m_Bytes = StreamHelper.ReadToEnd (mystream);

Function:

public static byte[] ReadToEnd(System.IO.Stream stream)
{
    long originalPosition = 0;

    if(stream.CanSeek)
    {
         originalPosition = stream.Position;
         stream.Position = 0;
    }

    try
    {
        byte[] readBuffer = new byte[4096];

        int totalBytesRead = 0;
        int bytesRead;

        while ((bytesRead = stream.Read(readBuffer, totalBytesRead, readBuffer.Length - totalBytesRead)) > 0)
        {
            totalBytesRead += bytesRead;

            if (totalBytesRead == readBuffer.Length)
            {
                int nextByte = stream.ReadByte();
                if (nextByte != -1)
                {
                    byte[] temp = new byte[readBuffer.Length * 2];
                    Buffer.BlockCopy(readBuffer, 0, temp, 0, readBuffer.Length);
                    Buffer.SetByte(temp, totalBytesRead, (byte)nextByte);
                    readBuffer = temp;
                    totalBytesRead++;
                }
            }
        }

        byte[] buffer = readBuffer;
        if (readBuffer.Length != totalBytesRead)
        {
            buffer = new byte[totalBytesRead];
            Buffer.BlockCopy(readBuffer, 0, buffer, 0, totalBytesRead);
        }
        return buffer;
    }
    finally
    {
        if(stream.CanSeek)
        {
             stream.Position = originalPosition; 
        }
    }
}

Write your event handler declaration like this:

<a href="#" onclick="myFunc(event,1,2,3)">click</a>

Then your "myFunc()" function can access the event.

The string value of the "onclick" attribute is converted to a function in a way that's almost exactly the same as the browser (internally) calling the Function constructor:

theAnchor.onclick = new Function("event", theOnclickString);

(except in IE). However, because "event" is a global in IE (it's a window attribute), you'll be able to pass it to the function that way in any browser.

You can simply do:

var ms = new MemoryStream(File.ReadAllBytes(filePath));

Stream position is 0 and ready to use.

You could whip up a little helper function to do this:

/**
 * Determines if $number is between $min and $max
 *
 * @param  integer  $number     The number to test
 * @param  integer  $min        The minimum value in the range
 * @param  integer  $max        The maximum value in the range
 * @param  boolean  $inclusive  Whether the range should be inclusive or not
 * @return boolean              Whether the number was in the range
 */
function in_range($number, $min, $max, $inclusive = FALSE)
{
    if (is_int($number) && is_int($min) && is_int($max))
    {
        return $inclusive
            ? ($number >= $min && $number <= $max)
            : ($number > $min && $number < $max) ;
    }

    return FALSE;
}

And you would use it like so:

var_dump(in_range(5, 0, 10));        // TRUE
var_dump(in_range(1, 0, 1));         // FALSE
var_dump(in_range(1, 0, 1, TRUE));   // TRUE
var_dump(in_range(11, 0, 10, TRUE)); // FALSE

// etc...

CSS:

.headercss {
    width: 100%;
    height: 320px;
    background-color: #000000;
    position: fixed;
}

Attribute position: fixed will keep it stuck, while other content will be scrollable. Don't forget to set width:100% to make it fill fully to the right.

Example

Better use PHP_EOL ("End Of Line") instead. It's cross-platform.

E.g.:

$unit1 = 'paragrahp1';
$unit2 = 'paragrahp2';
echo '<p>' . $unit1 . '</p>' . PHP_EOL;
echo '<p>' . $unit2 . '</p>';

Make a state machine that operates on one basic principle: is the current character a number.

• When transitioning from non-digit to digit, you initialize your current_number := number.
• when transitioning from digit to digit, you "shift" the new digit in:
  current_number := current_number * 10 + number;
• when transitioning from digit to non-digit, you output the current_number
• when from non-digit to non-digit, you do nothing.

Optimizations are possible.

Either use LINQ:

var value = MyList.First(item => item.name == "foo").value;

(This will just find the first match, of course. There are lots of options around this.)

Or use Find instead of FindIndex:

var value = MyList.Find(item => item.name == "foo").value;

I'd strongly suggest using LINQ though - it's a much more idiomatic approach these days.

(I'd also suggest following the .NET naming conventions.)

firstly u have to import numpy library (refer code for making a numpy array) shape only gives the output only if the variable is attribute of numpy library .in other words it must be a np.array or any other data structure of numpy. Eg.

`>>> import numpy
>>> a=numpy.array([[1,1],[1,1]])
>>> a.shape
(2, 2)`

You can directly go to Web IDE and upload your folder there.

Steps:

1. Go to Web IDE(Mostly located below the clone option).
2. Create new directory at your path
3. Upload your files and folders

In some cases you may not be able to directly upload entire folder containing folders, In such cases, you will have to create directory structure yourself.

node.innerHTML = "";

Non-standard, but fast and well supported.

From the command line, you can type svn mv path1 path2. This will create an add and a delete operation, but there's not really a way around that - as far as I know - in Subversion.

use numpy.round

import numpy as np
precision = 3
floats = [1.123123123, 2.321321321321]
new_float = np.round(floats, precision)

I typically have a secrets.py that is stored separately from my other python scripts and is not under version control. Then whenever required, you can do from secrets import <required_pwd_var>. This way you can rely on the operating systems in-built file security system without re-inventing your own.

Using Base64 encoding/decoding is also another way to obfuscate the password though not completely secure

More here - Hiding a password in a python script (insecure obfuscation only)

This pointed me in the right direction, but I have a DB that originated in MSSQL 2000 and is still using the ntext data type for the column I was replacing on. When you try to run REPLACE on that type you get this error:

Argument data type ntext is invalid for argument 1 of replace function.

The simplest fix, if your column data fits within nvarchar, is to cast the column during replace. Borrowing the code from the accepted answer:

UPDATE YourTable
SET Column1 = REPLACE(cast(Column1 as nvarchar(max)),'a','b')
WHERE Column1 LIKE '%a%'

This worked perfectly for me. Thanks to this forum post I found for the fix. Hopefully this helps someone else!

You can remove in two ways

var output = from x in authorsList
             where x.firstname != "Bob"
             select x;

or

var authors = from x in authorsList
              where x.firstname == "Bob"
              select x;

var output = from x in authorsList
             where !authors.Contains(x) 
             select x;

I had same issue, if you want simple output based on your where condition , then first solution is better.

Something to keep in mind when creating formatters is to try to reuse the same instance if you can, as formatters are fairly computationally expensive to create. The following is a pattern I frequently use for apps where I can share the same formatter app-wide, adapted from NSHipster.

extension DateFormatter {

    static var sharedDateFormatter: DateFormatter = {
        let dateFormatter = DateFormatter()   
        // Add your formatter configuration here     
        dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
        return dateFormatter
    }()
}

Usage:

let dateString = DateFormatter.sharedDateFormatter.string(from: Date())

If your array is static or global it's initialized to zero before main() starts. That would be the most efficient option.

InvariantCulture

Uses a "standard" set of character orderings (a,b,c, ... etc.). This is in contrast to some specific locales, which may sort characters in different orders ('a-with-acute' may be before or after 'a', depending on the locale, and so on).

Ordinal

On the other hand, looks purely at the values of the raw byte(s) that represent the character.

There's a great sample at http://msdn.microsoft.com/en-us/library/e6883c06.aspx that shows the results of the various StringComparison values. All the way at the end, it shows (excerpted):

StringComparison.InvariantCulture:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is less than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

StringComparison.Ordinal:
LATIN SMALL LETTER I (U+0069) is less than LATIN SMALL LETTER DOTLESS I (U+0131)
LATIN SMALL LETTER I (U+0069) is greater than LATIN CAPITAL LETTER I (U+0049)
LATIN SMALL LETTER DOTLESS I (U+0131) is greater than LATIN CAPITAL LETTER I (U+0049)

You can see that where InvariantCulture yields (U+0069, U+0049, U+00131), Ordinal yields (U+0049, U+0069, U+00131).

You can create your own JSONObject then toString().

Remember run it in the background thread like doInBackground in AsyncTask.

OkHttp version > 4:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

val client = OkHttpClient()
val mediaType = "application/json; charset=utf-8".toMediaType()
val body = jsonObject.toString().toRequestBody(mediaType)
val request: Request = Request.Builder()
            .url("https://YOUR_URL/")
            .post(body)
            .build()

var response: Response? = null
try {
    response = client.newCall(request).execute()
    val resStr = response.body!!.string()
} catch (e: IOException) {
    e.printStackTrace()
}
   

OkHttp version 3:

// create your json here
JSONObject jsonObject = new JSONObject();
try {
    jsonObject.put("KEY1", "VALUE1");
    jsonObject.put("KEY2", "VALUE2");
} catch (JSONException e) {
    e.printStackTrace();
}

  OkHttpClient client = new OkHttpClient();
  MediaType JSON = MediaType.parse("application/json; charset=utf-8");
  // put your json here
  RequestBody body = RequestBody.create(JSON, jsonObject.toString());
  Request request = new Request.Builder()
                    .url("https://YOUR_URL/")
                    .post(body)
                    .build();

  Response response = null;
  try {
      response = client.newCall(request).execute();
      String resStr = response.body().string();
  } catch (IOException e) {
      e.printStackTrace();
  }

You can loop over each row of the DataTable and check the value.

I'm a big fan of using a foreach loop when using IEnumerables. Makes it very simple and clean to look at or process each row

DataTable dtPs = // ... initialize your DataTable
foreach (DataRow dr in dtPs.Rows)
{
    if (dr["item_manuf_id"].ToString() == "some value")
    {
        // do your deed
    }
}

Alternatively you can use a PrimaryKey for your DataTable. This helps in various ways, but you often need to define one before you can use it.

An example of using one if at http://msdn.microsoft.com/en-us/library/z24kefs8(v=vs.80).aspx

DataTable workTable = new DataTable("Customers");

// set constraints on the primary key
DataColumn workCol = workTable.Columns.Add("CustID", typeof(Int32));
workCol.AllowDBNull = false;
workCol.Unique = true;

workTable.Columns.Add("CustLName", typeof(String));
workTable.Columns.Add("CustFName", typeof(String));
workTable.Columns.Add("Purchases", typeof(Double));

// set primary key
workTable.PrimaryKey = new DataColumn[] { workTable.Columns["CustID"] };

Once you have a primary key defined and data populated, you can use the Find(...) method to get the rows that match your primary key.

Take a look at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx

DataRow drFound = dtPs.Rows.Find("some value");
if (drFound["item_manuf_id"].ToString() == "some value")
{
    // do your deed
}

Finally, you can use the Select() method to find data within a DataTable also found at at http://msdn.microsoft.com/en-us/library/y06xa2h1(v=vs.80).aspx.

String sExpression = "item_manuf_id == 'some value'";
DataRow[] drFound;
drFound = dtPs.Select(sExpression);

foreach (DataRow dr in drFound)
{
    // do you deed. Each record here was already found to match your criteria
}

3. Turn off MIUI optimization.

Because, it is not supposed to do that.

input[type=text] { } is an attribute selector, and will only select those element, with the matching attribute.

similar to above, I got the dart sdk path from a project I created with flutter(not cloned) by going to Android Studio Preferences | Languages & Frameworks | Dart. Then similarly in the cloned project go to Preferences | Languages & Frameworks | Dart and "Enable Dart support for the project..." and enter the path you saved.

A general solution:

import random
def weighted_choice(choices, weights):
    total = sum(weights)
    treshold = random.uniform(0, total)
    for k, weight in enumerate(weights):
        total -= weight
        if total < treshold:
            return choices[k]

The simplest non recursive way is:

for d in */; do
    echo "$d"
done

The / at the end tells, use directories only.

There is no need for

• find
• awk
• ...

You have to fetch the whole data in the list and then do the iteration as it is a file and will become inefficient otherwise.

private static final Type REVIEW_TYPE = new TypeToken<List<Review>>() {
}.getType();
Gson gson = new Gson();
JsonReader reader = new JsonReader(new FileReader(filename));
List<Review> data = gson.fromJson(reader, REVIEW_TYPE); // contains the whole reviews list
data.toScreen(); // prints to screen some values

I'll add to this, because some of these answers seem out of date. Here's how I do it:

<class="ng-class:isSelected">

Where 'isSelected' is a javascript variable defined within the scoped angular controller.


To more specifically address your question, here's how you might generate a list with that:

HTML

<div ng-controller="ListCtrl">  
    <li class="ng-class:item.isSelected" ng-repeat="item in list">   
       {{item.name}}
    </li>  
</div>

JS

function ListCtrl($scope) {    
    $scope.list = [  
        {"name": "Item 1", "isSelected": "active"},  
        {"name": "Item 2", "isSelected": ""}
    ]
}

EDIT: As mentioned by Stephen Niedzielski in his comment, the issue seems to come from the 32-bit being of the JRE, which is de facto, looking for the 32-bit version of libXtst6. To install the required version of the library:

$ sudo apt-get install libxtst6:i386

Type:

$ sudo apt-get update
$ sudo apt-get install libxtst6

If this isn’t OK, type:

$ sudo updatedb
$ locate libXtst

it should return something like:

/usr/lib/x86_64-linux-gnu/libXtst.so.6       # Mine is OK
/usr/lib/x86_64-linux-gnu/libXtst.so.6.1.0

If you do not have libXtst.so.6 but do have libXtst.so.6.X.X create a symbolic link:

$ cd /usr/lib/x86_64-linux-gnu/
$ ln -s libXtst.so.6 libXtst.so.6.X.X

Hope this helps.

EF 6

In my scenario, Entity Framework was not picking up the newly updated data. The reason might be the data was updated outside of its scope. Refreshing data after fetching resolved my issue.

private void RefreshData(DBEntity entity)
{
    if (entity == null) return;

    ((IObjectContextAdapter)DbContext).ObjectContext.RefreshAsync(RefreshMode.StoreWins, entity);
}

private void RefreshData(List<DBEntity> entities)
{
    if (entities == null || entities.Count == 0) return;

    ((IObjectContextAdapter)DbContext).ObjectContext.RefreshAsync(RefreshMode.StoreWins, entities);
}

Use ?? operator at the end of your <#if> statement.

This example demonstrates how to handle null values for two lists in a Freemaker template.

List of cars:
<#if cars??>
    <#list cars as car>${car.owner};</#list>
</#if>
List of motocycles:
<#if motocycles??>
    <#list motocycles as motocycle>${motocycle.owner};</#list>
</#if>

You can use getEventListeners in your Google Chrome developer console.

getEventListeners(object) returns the event listeners registered on the specified object.

getEventListeners(document.querySelector('option[value=Closed]'));

git log -1 will display the latest commit message or git log -1 --oneline if you only want the sha1 and associated commit message to be displayed.

The equivalent syntax since DataTables 1.10+ is rowCallback

"rowCallback": function( row, data, index ) {
    if ( data[2] == "5" )
    {
        $('td', row).css('background-color', 'Red');
    }
    else if ( data[2] == "4" )
    {
        $('td', row).css('background-color', 'Orange');
    }
}

One of the previous answers mentions createdRow. That may give similar results under some conditions, but it is not the same. For example, if you use draw() after updating a row's data, createdRow will not run. It only runs once. rowCallback will run again.

document.getElementById('TextBoxID').readOnly = true;    //to enable readonly


document.getElementById('TextBoxID').readOnly = false;   //to  disable readonly

Check field type in table just save time stamp value in datatype like bigint etc.

Not datetime type

I'm using FileStream and having same issue.. When ever Two request try to read same file it throw this exception.

solution use FileShare

using FileStream fs = System.IO.File.Open(filePath, FileMode.Open, FileAccess.Read, FileShare.Read);

I'm Just Reading a file concurrently FileShare.Read solve my issue.

"Why does a scipy get so complicated?

It gets so complicated because Python's package management system is built to track Python package dependencies, and SciPy and other scientific tools have dependencies beyond Python. Wheels fix part of the problem, but my experience is that tools like pip/virtualenv are just not sufficient for installing and managing a scientific Python stack.

If you want an easy way to get up and running with SciPy, I would highly suggest the Anaconda distribution. It will give you everything you need for scientific computing in Python.

If you want a "short way" of doing this (I'm interpreting that as "I don't want to install a huge distribution"), you might try miniconda and then run conda install scipy.

You can install as pip install mysqlclient

The easiest way would be to make use of the GROUP_CONCAT group function here..

select
  ordered_item.id as `Id`,
  ordered_item.Item_Name as `ItemName`,
  GROUP_CONCAT(Ordered_Options.Value) as `Options`
from
  ordered_item,
  ordered_options
where
  ordered_item.id=ordered_options.ordered_item_id
group by
  ordered_item.id

Which would output:

Id              ItemName       Options

1               Pizza          Pepperoni,Extra Cheese

2               Stromboli      Extra Cheese

That way you can have as many options as you want without having to modify your query.

Ah, if you see your results getting cropped, you can increase the size limit of GROUP_CONCAT like this:

SET SESSION group_concat_max_len = 8192;

For all the standard library types the member function empty() is a query, not a command, i.e. it means "are you empty?" not "please throw away your contents".

The clear() member function is inherited from ios and is used to clear the error state of the stream, e.g. if a file stream has the error state set to eofbit (end-of-file), then calling clear() will set the error state back to goodbit (no error).

For clearing the contents of a stringstream, using:

m.str("");

is correct, although using:

m.str(std::string());

is technically more efficient, because you avoid invoking the std::string constructor that takes const char*. But any compiler these days should be able to generate the same code in both cases - so I would just go with whatever is more readable.

Use following snippet in your code

Intent newIntent = new Intent(Intent.ACTION_VIEW, 
Uri.parse("https://www.google.co.in/?gws_rd=cr"));
startActivity(newIntent);

You can do the following (which I find trivial, but its actually correct). For anyone trying to find how to initialize a two-dimensional array in TypeScript (like myself).

Let's assume that you want to initialize a two-dimensional array, of any type. You can do the following

const myArray: any[][] = [];

And later, when you want to populate it, you can do the following:

myArray.push([<your value goes here>]);

A short example of the above can be the following:

const myArray: string[][] = [];
myArray.push(["value1", "value2"]);

The selected answer is clever and tricky. Here's how I did it:

LoginActivity is the root activity of the task, set android:noHistory="true" to it in Manifest.xml; Say you want to logout from SettingsActivity, you can do it as below:

    Intent i = new Intent(SettingsActivity.this, LoginActivity.class);
    i.addFlags(IntentCompat.FLAG_ACTIVITY_CLEAR_TASK
            | Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);

I think you need OpenSessionInViewFilter to keep your session open during view rendering (but it is not too good practice).

I add this answer because I think it could be useful to anybody.

I step into the problem of setting RGBA colors (that is, RGB color with an Alpha value for transparency) for color display labels in my painting application.

As I came across the first answer, I was unable to set an RGBA color. I have also tried things like:

myLabel.setStyleSheet("QLabel { background-color : %s"%color.name())

where color is an RGBA color.

So, my dirty solution was to extend QLabel and override paintEvent() method filling its bounding rect.

Today, I've open up the qt-assistant and read the style reference properties list. Affortunately, it has an example that states the following:

QLineEdit { background-color: rgb(255, 0, 0) }

Thats open up my mind in doing something like the code below, as an example:

myLabel= QLabel()
myLabel.setAutoFillBackground(True) # This is important!!
color  = QtGui.QColor(233, 10, 150)
alpha  = 140
values = "{r}, {g}, {b}, {a}".format(r = color.red(),
                                     g = color.green(),
                                     b = color.blue(),
                                     a = alpha
                                     )
myLabel.setStyleSheet("QLabel { background-color: rgba("+values+"); }")

Note that setAutoFillBackground() set in False will not make it work.

Regards,

The /P switch allows you to set the value of a variable to a line of input entered by the user. Displays the specified promptString before reading the line of input. The promptString can be empty.

Two ways I've used it... first:

SET /P variable=

When batch file reaches this point (when left blank) it will halt and wait for user input. Input then becomes variable.

And second:

SET /P variable=<%temp%\filename.txt

Will set variable to contents (the first line) of the txt file. This method won't work unless the /P is included. Both tested on Windows 8.1 Pro, but it's the same on 7 and 10.

You cannot "convert" an existing column into an IDENTITY column - you will have to create a new column as INT IDENTITY:

ALTER TABLE ProductInProduct 
ADD NewId INT IDENTITY (1, 1);

Update:

OK, so there is a way of converting an existing column to IDENTITY. If you absolutely need this - check out this response by Martin Smith with all the gory details.

First, the signature of your data() function:

bool data(struct *sampleData)

cannot possibly work, because the argument lacks a name. When you declare a function argument that you intend to actually access, it needs a name. So change it to something like:

bool data(struct sampleData *samples)

But in C++, you don't need to use struct at all actually. So this can simply become:

bool data(sampleData *samples)

Second, the sampleData struct is not known to data() at that point. So you should declare it before that:

struct sampleData {
    int N;
    int M;
    string sample_name;
    string speaker;
};

bool data(sampleData *samples)
{
    samples->N = 10;
    samples->M = 20;
    // etc.
}

And finally, you need to create a variable of type sampleData. For example, in your main() function:

int main(int argc, char *argv[]) {
    sampleData samples;
    data(&samples);
}

Note that you need to pass the address of the variable to the data() function, since it accepts a pointer.

However, note that in C++ you can directly pass arguments by reference and don't need to "emulate" it with pointers. You can do this instead:

// Note that the argument is taken by reference (the "&" in front
// of the argument name.)
bool data(sampleData &samples)
{
    samples.N = 10;
    samples.M = 20;
    // etc.
}

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

    // No need to pass a pointer here, since data() takes the
    // passed argument by reference.
    data(samples);
}

Using the request module solved the issue.

// Include the request library for Node.js   
var request = require('request');
//  Basic Authentication credentials   
var username = "vinod"; 
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(   
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }  
},
 function (error, response, body) {
 console.log(body); }  );         

Just add -o nonempty in command line, like this:

s3fs -o nonempty  <bucket-name> </mount/point/>

• This code compiles and runs smoothly.
• It uses no iterator so more readable.
• list is your collection.
• result is filtered form (no null no empty).

public static void listRemove() {
    List<String> list = Arrays.asList("", "Hi", "", "How", "are", "you");
    List<String> result = new ArrayList<String>();

    for (String str : list) {
        if (str != null && !str.isEmpty()) {
            result.add(str);
        }
    }

    System.out.println(result);
}

invoking mvn exec:java on the command line will invoke the plugin which is configured to execute the class org.dhappy.test.NeoTraverse.

So, to trigger the plugin from the command line, just run:

mvn exec:java

Now, if you want to execute the exec:java goal as part of your standard build, you'll need to bind the goal to a particular phase of the default lifecycle. To do this, declare the phase to which you want to bind the goal in the execution element:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>exec-maven-plugin</artifactId>
  <version>1.4</version>
  <executions>
    <execution>
      <id>my-execution</id>
      <phase>package</phase>
      <goals>
        <goal>java</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <mainClass>org.dhappy.test.NeoTraverse</mainClass>
  </configuration>
</plugin>

With this example, your class would be executed during the package phase. This is just an example, adapt it to suit your needs. Works also with plugin version 1.1.

How about -

time.strftime("%Y-%m-%dT%H:%M:%SZ", time.gmtime(seconds))

if seconds is None then it converts the local time to UTC time else converts the passed in time to UTC.

Since Python 3 timedelta supports multiplication with floats, so now you can do:

import random
random_date = start + (end - start) * random.random()

given that start and end are of the type datetime.datetime. For example, to generate a random datetime within the next day:

import random
from datetime import datetime, timedelta

start = datetime.now()
end = start + timedelta(days=1)
random_date = start + (end - start) * random.random()

I had the same problem, but setting windowSoftInputMode did not help, and I did not want to change the upper view to have isScrollContainer="false" because I wanted it to scroll.

My solution was to define the top location of the navigation tools instead of the bottom. I'm using Titanium, so I'm not sure exactly how this would translate to android. Defining the top location of the navigation tools view prevented the soft keyboard from pushing it up, and instead covered the nav controls like I wanted.

Try adding a Reference to System.Configuration, you get some of the configuration namespace by referencing the System namespace, adding the reference to System.Configuration should allow you to access ConfigurationManager.

I just did the same. If you look in the "Android SDK Manager" in the "Android 4.0 (API 14)" section you'll see a few packages. One of these is named "ARM EABI v7a System Image".

This is what you need to download in order to create an Android 4.0 virtual device:

Outer joins can offer superior performance when used in views.

Say you have a query that involves a view, and that view is comprised of 10 tables joined together. Say your query only happens to use columns from 3 out of those 10 tables.

If those 10 tables had been inner-joined together, then the query optimizer would have to join them all even though your query itself doesn't need 7 out of 10 of the tables. That's because the inner joins themselves might filter down the data, making them essential to compute.

If those 10 tables had been outer-joined together instead, then the query optimizer would only actually join the ones that were necessary: 3 out of 10 of them in this case. That's because the joins themselves are no longer filtering the data, and thus unused joins can be skipped.

winrm set winrm/config/client '@{TrustedHosts="machineA,machineB"}'

I have combined all the above answers into a script that polls the counters and writes the measurements in the terminal:

$totalRam = (Get-CimInstance Win32_PhysicalMemory | Measure-Object -Property capacity -Sum).Sum
while($true) {
    $date = Get-Date -Format "yyyy-MM-dd HH:mm:ss"
    $cpuTime = (Get-Counter '\Processor(_Total)\% Processor Time').CounterSamples.CookedValue
    $availMem = (Get-Counter '\Memory\Available MBytes').CounterSamples.CookedValue
    $date + ' > CPU: ' + $cpuTime.ToString("#,0.000") + '%, Avail. Mem.: ' + $availMem.ToString("N0") + 'MB (' + (104857600 * $availMem / $totalRam).ToString("#,0.0") + '%)'
    Start-Sleep -s 2
}

This produces the following output:

2020-02-01 10:56:55 > CPU: 0.797%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:56:59 > CPU: 0.447%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:03 > CPU: 0.089%, Avail. Mem.: 2,118MB (51.7%)
2020-02-01 10:57:07 > CPU: 0.000%, Avail. Mem.: 2,118MB (51.7%)

You can hit Ctrl+C to abort the loop.

So, you can connect to any Windows machine with this command:

Enter-PSSession -ComputerName MyServerName -Credential MyUserName

...paste it in, and run it, to get a "live" measurement. If connecting to the machine doesn't work directly, take a look here.

TL&DR: When you typically get data from a server, it is sent in bytes. The rationale is that these bytes will need to be 'decoded' by the recipient, who should know how to use the data. You should decode the binary upon arrival to not get 'b' (bytes) but instead a string.

Use case:

import requests    
def get_data_from_url(url):
        response = requests.get(url_to_visit)
        response_data_split_by_line = response.content.decode('utf-8').splitlines()
        return response_data_split_by_line

In this example, I decode the content that I received into UTF-8. For my purposes, I then split it by line, so I can loop through each line with a for loop.

UPDATE: This question was the subject of my blog on May 12th 2011. Thanks for the great question!

Suppose you have an interface as you describe, and a hundred classes that implement it. Then you decide to make one of the parameters of one of the interface's methods optional. Are you suggesting that the right thing to do is for the compiler to force the developer to find every implementation of that interface method, and make the parameter optional as well?

Suppose we did that. Now suppose the developer did not have the source code for the implementation:

// in metadata:
public class B 
{ 
    public void TestMethod(bool b) {}
}

// in source code
interface MyInterface 
{ 
    void TestMethod(bool b = false); 
}
class D : B, MyInterface {}
// Legal because D's base class has a public method 
// that implements the interface method

How is the author of D supposed to make this work? Are they required in your world to call up the author of B on the phone and ask them to please ship them a new version of B that makes the method have an optional parameter?

That's not going to fly. What if two people call up the author of B, and one of them wants the default to be true and one of them wants it to be false? What if the author of B simply refuses to play along?

Perhaps in that case they would be required to say:

class D : B, MyInterface 
{
    public new void TestMethod(bool b = false)
    {
        base.TestMethod(b);
    }
}

The proposed feature seems to add a lot of inconvenience for the programmer with no corresponding increase in representative power. What's the compelling benefit of this feature which justifies the increased cost to the user?

UPDATE: In the comments below, supercat suggests a language feature that would genuinely add power to the language and enable some scenarios similar to the one described in this question. FYI, that feature -- default implementations of methods in interfaces -- will be added to C# 8.

Like this :

String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
List<String> wordList = new ArrayList<String>(Arrays.asList(words));

or

List myList = new ArrayList();
String[] words = {"000", "aaa", "bbb", "ccc", "ddd"};
Collections.addAll(myList, words);

You don't need to use

adb shell getevent -l

command, you just need to enable in Developer Options on the device [Show Touch data] to get X and Y.

Some more information can be found in my article here: https://mobileqablog.wordpress.com/2016/08/20/android-automatic-touchscreen-taps-adb-shell-input-touchscreen-tap/

A little example for JUnit 5 Jupiter, the "RunWith" was removed you now need to use the Extensions using the "@ExtendWith" Annotation.

@ExtendWith(MockitoExtension.class)
class FooTest {

  @InjectMocks
  ClassUnderTest test = new ClassUnderTest();

  @Spy
  SomeInject bla = new SomeInject();
}

As said before modulo isn't sufficient because it skews the distribution. Heres my code which masks off bits and uses them to ensure the distribution isn't skewed.

static uint32_t randomInRange(uint32_t a,uint32_t b) {
    uint32_t v;
    uint32_t range;
    uint32_t upper;
    uint32_t lower;
    uint32_t mask;

    if(a == b) {
        return a;
    }

    if(a > b) {
        upper = a;
        lower = b;
    } else {
        upper = b;
        lower = a; 
    }

    range = upper - lower;

    mask = 0;
    //XXX calculate range with log and mask? nah, too lazy :).
    while(1) {
        if(mask >= range) {
            break;
        }
        mask = (mask << 1) | 1;
    }


    while(1) {
        v = rand() & mask;
        if(v <= range) {
            return lower + v;
        }
    }

}

The following simple code lets you look at the distribution:

int main() {

    unsigned long long int i;


    unsigned int n = 10;
    unsigned int numbers[n];


    for (i = 0; i < n; i++) {
        numbers[i] = 0;
    }

    for (i = 0 ; i < 10000000 ; i++){
        uint32_t rand = random_in_range(0,n - 1);
        if(rand >= n){
            printf("bug: rand out of range %u\n",(unsigned int)rand);
            return 1;
        }
        numbers[rand] += 1;
    }

    for(i = 0; i < n; i++) {
        printf("%u: %u\n",i,numbers[i]);
    }

}

By default, MomentJS parses in local time. If only a date string (with no time) is provided, the time defaults to midnight.

In your code, you create a local date and then convert it to the UTC timezone (in fact, it makes the moment instance switch to UTC mode), so when it is formatted, it is shifted (depending on your local time) forward or backwards.

If the local timezone is UTC+N (N being a positive number), and you parse a date-only string, you will get the previous date.

Here are some examples to illustrate it (my local time offset is UTC+3 during DST):

>>> moment('07-18-2013', 'MM-DD-YYYY').utc().format("YYYY-MM-DD HH:mm")
"2013-07-17 21:00"
>>> moment('07-18-2013 12:00', 'MM-DD-YYYY HH:mm').utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 09:00"
>>> Date()
"Thu Jul 25 2013 14:28:45 GMT+0300 (Jerusalem Daylight Time)"

If you want the date-time string interpreted as UTC, you should be explicit about it:

>>> moment(new Date('07-18-2013 UTC')).utc().format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

or, as Matt Johnson mentions in his answer, you can (and probably should) parse it as a UTC date in the first place using moment.utc() and include the format string as a second argument to prevent ambiguity.

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').format("YYYY-MM-DD HH:mm")
"2013-07-18 00:00"

To go the other way around and convert a UTC date to a local date, you can use the local() method, as follows:

>>> moment.utc('07-18-2013', 'MM-DD-YYYY').local().format("YYYY-MM-DD HH:mm")
"2013-07-18 03:00"

I deactivated my "Arno's Iptables Firewall" for testing, and then the messages are gone

while (listBox1.Items.Count > 0){ 
    listBox1.Items.Remove(0);
}

ajavascript have two type of annotation for fetching javascript Object properties:

Obj = {};

1) (.) annotation eg. Obj.id this will only work if the object already have a property with name 'id'

2) ([]) annotation eg . Obj[id] here if the object does not have any property with name 'id',it will create a new property with name 'id'.

so for below example:

A new property will be created always when you write Obj[name]. And if the property already exist with the same name it will override it.

const obj = {}
    jQuery(itemsFromDom).each(function() {
      const element = jQuery(this)
      const name = element.attr('id')
      const value = element.attr('value')
      // This will work
      obj[name]= value;
    })

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

I second Dipaks' answer, but often just the text-indent is enough as you may/maynot be positioning the ul for better layout control.

ul li{
text-indent: -1em;
}

The date values from the text fields can be fetched by jquery's .val() Method like

var datestr1 = $('#datefield1-id').val();
var datestr2 = $('#datefield2-id').val();

I'd strongly recommend to parse the date strings before comparing them. Javascript's Date object has a parse()-Method, but it only supports US date formats (YYYY/MM/DD). It returns the milliseconds since the beginning of the unix epoch, so you can simply compare your values with > or <.

If you want different formats (e.g. ISO 8661), you need to resort to regular expressions or the free date.js library.

If you want to be super user-fiendly, you can use jquery ui datepickers instead of textfields. There is a datepicker variant that allows to enter date ranges:

http://www.filamentgroup.com/lab/date_range_picker_using_jquery_ui_16_and_jquery_ui_css_framework/

Use MoreLINQ, which has a DistinctBy method :)

IEnumerable<Car> distinctCars = cars.DistinctBy(car => car.CarCode);

(This is only for LINQ to Objects, mind you.)

char alphaStart = Char.Parse("A");
char alphaEnd = Char.Parse("Z");
for(char i = alphaStart; i <= alphaEnd; i++) {
    string anchorLetter = i.ToString();
}

If you do not want to include the jquery library you can simple do the following

a) ad an iframe, size 0px so it is not visible, href is blank

b) execute this within your js code function

 window.frames['iframename'].location.replace('http://....your.php');

This will execute the php script and you can for example make a database update...

In git bash, stashing of untracked files is achieved by using the command

git stash --include-untracked
# or
git stash -u

http://git-scm.com/docs/git-stash

git stash removes any untracked or uncommited files from your workspace. And you can revert git stash by using following commands

git stash pop

This will place the file back in your local workspace.

My experience

I had to perform a modification to my gitIgnore file to avoid movement of .classpath and .project files into remote repo. I am not allowed to move this modified .gitIgnore in remote repo as of now.

.classpath and .project files are important for eclipse - which is my java editor.

I first of all selectively added my rest of the files and committed for staging. However, final push cannot be performed unless the modified .gitIgnore fiels and the untracked files viz. .project and .classpath are not stashed.

I used

git stash

for stashing the modified .gitIgnore file.

For stashing .classpath and .project file, I used

git stash --include-untracked

and it removed the files from my workspace. Absence of these files takes away my capability of working on my work location in eclipse. I proceeded on with completing the procedure for pushing the committed files to remote. Once this was done successfully, I used

git stash pop

This pasted the same files back in my workspace. This gave back to me my ability to work on the same project in eclipse. Hope this brushes aside misconceptions.

Using Node Version Manager (NVM):

Install it:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

Test your installation:

close your current terminal, open a new terminal, and run:

command -v nvm

Use it to install as many versions as u like:

nvm install 8              # Install nodejs 8
nvm install --lts          # Install latest LTS (Long Term Support) version

List installed versions:

nvm ls

Use a specific version:

nvm use 8                  # Use this version on this shell

Set defaults:

nvm alias default 8        # Default to nodejs 8 on this shell
nvm alias default node     # always use latest available as default nodejs for all shells

I know that lots of other people have found solutions that worked for their particular case, but since none of them worked for my particular case, I thought this might be helpful to someone else.

Some details:

I'm using google maps API v3 on a project where inline CSS is something we really, really want to avoid. My infowindows were working for everything except for IE11, where the width was not calculated correctly. This resulted in div overflows, which triggered scrollbars.

I had to do three things:

1. Remove all display: inline-block style rules from anything inside of the infowindow content (I replaced with display: block) - I got the idea to try this from a thread (which I can't find anymore) where someone was having the same problem with IE6.

2. Pass the content as a DOM node instead of as a string. I am using jQuery, so I could do this by replacing: infowindow.setContent(infoWindowDiv.html()); with infowindow.setContent($(infoWindowDiv.html())[0]); This turned out to be easiest for me, but there are lots of other ways to get the same result.

3. Use the "setMaxWidth" hack - set the MaxWidth option in the constructor - setting the option later doesn't work. If you don't really want a max width, just set it to a very large number.

I don't know why these worked, and I'm not sure if a subset of them would work. I know that none of them work for all of my use cases individually, and that 2 + 3 doesn't work. I didn't have time to test 1 + 2 or 1 + 3.

Also, be aware of differences in casting, especially when working with bitmasks, due to casting to signed char:

bool a = 0x0100;
a == true;  // expression true

BOOL b = 0x0100;
b == false; // expression true on !((TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH), e.g. MacOS
b == true;  // expression true on (TARGET_OS_IPHONE && __LP64__) || TARGET_OS_WATCH

If BOOL is a signed char instead of a bool, the cast of 0x0100 to BOOL simply drops the set bit, and the resulting value is 0.

EDIT: Are you using canvas transforms? If so, you'll have to track the transformation matrix. The following method should measure the height of text with the initial transform.

EDIT #2: Oddly the code below does not produce correct answers when I run it on this StackOverflow page; it's entirely possible that the presence of some style rules could break this function.

The canvas uses fonts as defined by CSS, so in theory we can just add an appropriately styled chunk of text to the document and measure its height. I think this is significantly easier than rendering text and then checking pixel data and it should also respect ascenders and descenders. Check out the following:

var determineFontHeight = function(fontStyle) {
  var body = document.getElementsByTagName("body")[0];
  var dummy = document.createElement("div");
  var dummyText = document.createTextNode("M");
  dummy.appendChild(dummyText);
  dummy.setAttribute("style", fontStyle);
  body.appendChild(dummy);
  var result = dummy.offsetHeight;
  body.removeChild(dummy);
  return result;
};

//A little test...
var exampleFamilies = ["Helvetica", "Verdana", "Times New Roman", "Courier New"];
var exampleSizes = [8, 10, 12, 16, 24, 36, 48, 96];
for(var i = 0; i < exampleFamilies.length; i++) {
  var family = exampleFamilies[i];
  for(var j = 0; j < exampleSizes.length; j++) {
    var size = exampleSizes[j] + "pt";
    var style = "font-family: " + family + "; font-size: " + size + ";";
    var pixelHeight = determineFontHeight(style);
    console.log(family + " " + size + " ==> " + pixelHeight + " pixels high.");
  }
}

You'll have to make sure you get the font style correct on the DOM element that you measure the height of but that's pretty straightforward; really you should use something like

var canvas = /* ... */
var context = canvas.getContext("2d");
var canvasFont = " ... ";
var fontHeight = determineFontHeight("font: " + canvasFont + ";");
context.font = canvasFont;
/*
  do your stuff with your font and its height here.
*/

In a standard context, each connected user holds an explorer.exe process: The command [tasklist /V|find "explorer"] returns a line that contains the explorer.exe process owner's, with an adapted regex it is possible to obtain the required value. This also runs perfectly under Windows 7.

In rare cases explorer.exe is replaced by another program, the find filter can be adapted to match this case. If the command return an empty line then it is likely that no user is logged on. With Windows 7 it is also possible to run [query session|find ">"].

no_of_lines = 5
lines = ""
for i in xrange(5):
    lines+=input()+"\n"
    a=raw_input("if u want to continue (Y/n)")
    ""
    if(a=='y'):
        continue
    else:
        break
    print lines

I was facing a similar issue with the DropDownButton when i was trying to display a dynamic list of strings in the dropdown. I ended up creating a plugin : flutter_search_panel. Not a dropdown plugin, but you can display the items with the search functionality.

Use the following code for using the widget :

    FlutterSearchPanel(
        padding: EdgeInsets.all(10.0),
        selected: 'a',
        title: 'Demo Search Page',
        data: ['This', 'is', 'a', 'test', 'array'],
        icon: new Icon(Icons.label, color: Colors.black),
        color: Colors.white,
        textStyle: new TextStyle(color: Colors.black, fontWeight: FontWeight.bold, fontSize: 20.0, decorationStyle: TextDecorationStyle.dotted),
        onChanged: (value) {
          print(value);
        },
   ),

Use a Flexbox, and put the border on the form.

The best way to do this now (2019) is with a flexbox.

• Put the border on the containing element (in this case I've used the form, but you could use a div).
• Use a flexbox layout to arrange the input and the button side by side. Allow the input to stretch to take up all available space.
• Now hide the input by removing its border.

Run the snippet below to see what you get.

form {_x000D_
  /* This bit sets up the horizontal layout */_x000D_
  display:flex;_x000D_
  flex-direction:row;_x000D_
  _x000D_
  /* This bit draws the box around it */_x000D_
  border:1px solid grey;_x000D_
_x000D_
  /* I've used padding so you can see the edges of the elements. */_x000D_
  padding:2px;_x000D_
}_x000D_
_x000D_
input {_x000D_
  /* Tell the input to use all the available space */_x000D_
  flex-grow:2;_x000D_
  /* And hide the input's outline, so the form looks like the outline */_x000D_
  border:none;_x000D_
}_x000D_
_x000D_
input:focus {_x000D_
  /* removing the input focus blue box. Put this on the form if you like. */_x000D_
  outline: none;_x000D_
}_x000D_
_x000D_
button {_x000D_
  /* Just a little styling to make it pretty */_x000D_
  border:1px solid blue;_x000D_
  background:blue;_x000D_
  color:white;_x000D_
}

<form>_x000D_
  <input />_x000D_
  <button>Go</button>_x000D_
</form>

Why this is good

• It will stretch to any width.
• The button will always be just as big as it needs to be. It won't stretch if the screen is wide, or shrink if the screen is narrow.
• The input text will not go behind the button.

Caveats and Browser Support

There's limited Flexbox support in IE9, so the button will not be on the right of the form. IE9 has not been supported by Microsoft for some years now, so I'm personally quite comfortable with this.

I've used minimal styling here. I've left in the padding to show the edges of things. You can obviously make this look however you want it to look with rounded corners, drop shadows, etc..

Some people use the term "primary key" to mean exactly an integer column that gets its values generated by some automatic mechanism. For example AUTO_INCREMENT in MySQL or IDENTITY in Microsoft SQL Server. Are you using primary key in this sense?

If so, the answer depends on the brand of database you're using. In MySQL, you can't do this, you get an error:

mysql> create table foo (
  id int primary key auto_increment, 
  id2 int auto_increment
);
ERROR 1075 (42000): Incorrect table definition; 
there can be only one auto column and it must be defined as a key

In some other brands of database, you are able to define more than one auto-generating column in a table.

You can always JQuery-ize your form.submit, but it may just call the same thing:

$("form").submit(); // probably able to affect multiple forms (good or bad)

// or you can address it by ID
$("#yourFormId").submit();

You can also attach functions to the submit event, but that is a different concept.

just write /Library/Java/JavaVirtualMachines/
in Go to Folder --> Go in Finder

It's not an official term. I guess it means knowledge of the Java language itself and the most important parts of the standard API (java.lang, java.io, java.utils packages, basically), as opposed to the multitude of specialzed APIs and frameworks (J2EE, JPA, JNDI, JSTL, ...) that are often required for Java jobs.

Python long can be arbitrarily large. If you need a value that's greater than any other value, you can use float('inf'), since Python has no trouble comparing numeric values of different types. Similarly, for a value lesser than any other value, you can use float('-inf').

Service vs Factory

The difference between factory and service is just like the difference between a function and an object

Factory Provider

• Gives us the function's return value ie. You just create an object, add properties to it, then return that same object.When you pass this service into your controller, those properties on the object will now be available in that controller through your factory. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Factory are a great way for communicating between controllers like sharing data.

• Can use other dependencies

• Usually used when the service instance requires complex creation logic

• Cannot be injected in .config() function.

• Used for non configurable services

• If you're using an object, you could use the factory provider.

• Syntax: module.factory('factoryName', function);

Service Provider

• Gives us the instance of a function (object)- You just instantiated with the ‘new’ keyword and you’ll add properties to ‘this’ and the service will return ‘this’.When you pass the service into your controller, those properties on ‘this’ will now be available on that controller through your service. (Hypothetical Scenario)

• Singleton and will only be created once

• Reusable components

• Services are used for communication between controllers to share data

• You can add properties and functions to a service object by using the this keyword

• Dependencies are injected as constructor arguments

• Used for simple creation logic

• Cannot be injected in .config() function.

• If you're using a class you could use the service provider

• Syntax: module.service(‘serviceName’, function);

Sample Demo

In below example I have define MyService and MyFactory. Note how in .service I have created the service methods using this.methodname. In .factory I have created a factory object and assigned the methods to it.

AngularJS .service

module.service('MyService', function() {

    this.method1 = function() {
            //..method1 logic
        }

    this.method2 = function() {
            //..method2 logic
        }
});

AngularJS .factory

module.factory('MyFactory', function() {

    var factory = {}; 

    factory.method1 = function() {
            //..method1 logic
        }

    factory.method2 = function() {
            //..method2 logic
        }

    return factory;
});

Angular.js: service vs provider vs factory?

At the time of this post all major browsers disable CSS transitions if you try to change the display property, but CSS animations still work fine so we can use them as a workaround.

Example Code (you can apply it to your menu accordingly) Demo:

Add the following CSS to your stylesheet:

@-webkit-keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}
@keyframes fadeIn {
    from { opacity: 0; }
      to { opacity: 1; }
}

Then apply the fadeIn animation to the child on parent hover (and of course set display: block):

.parent:hover .child {
    display: block;
    -webkit-animation: fadeIn 1s;
    animation: fadeIn 1s;
}

Update 2019 - Method that also supports fading out:

(Some JavaScript code is required)

// We need to keep track of faded in elements so we can apply fade out later in CSS_x000D_
document.addEventListener('animationstart', function (e) {_x000D_
  if (e.animationName === 'fade-in') {_x000D_

Example. To find number of vowels within the string

var word='Web Development Tutorial';
var vowels='[aeiou]'; 
var re = new RegExp(vowels, 'gi');
var arr = word.match(re);
document.write(arr.length);

I had a similar issue and it turned out that i had to add an extra entry in cmake to include the files.

Since i was also using the zmq library I had to add this to the included libraries as well.

In Javascript the idea of boolean is fairly ambiguous. Consider this:

 var bool = 0 
 if(bool){..} //evaluates to false

 if(//uninitialized var) //evaluates to false

So when you're using an if statement, (or any other control statement), one does not have to use a "boolean" type var. Therefore, in my opinion, the "=== true" part of your statement is unnecessary if you know it is a boolean, but absolutely necessary if your value is an ambiguous "truthy" var. More on booleans in javscript can be found here.

I found that I can't successfully add the event listener unless I pass true like so:

componentDidMount = () => {
    window.addEventListener('scroll', this.handleScroll, true);
},

Try setting the charset on your Content-Type:

httpCon.setRequestProperty( "Content-Type", "multipart/form-data; charset=UTF-8; boundary=" + boundary );

function is_array_assoc($foo) {
    if (is_array($foo)) {
        return (count(array_filter(array_keys($foo), 'is_string')) > 0);
    }
    return false;
}

public static bool EqualsAny<T>(IEquatable<T> value, params T[] possibleMatches) {
    foreach (T t in possibleMatches) {
        if (value.Equals(t))
            return true;
    }
    return false;
}
public static bool EqualsAny<T>(IEquatable<T> value, IEnumerable<T> possibleMatches) {
    foreach (T t in possibleMatches) {
        if (value.Equals(t))
            return true;
    }
    return false;
}

pure JavaScript is not that difficult:

for(var i=0; i < form.elements.length; i++){
    var e = form.elements[i];
    console.log(e.name+"="+e.value);
}

Note: because form.elements is a object for-in loop does not work as expected.

Answer found here (by Chris Pietschmann), documented here (W3S).

Like the other answers you can do theTypeIs = Object.keys(myVar)[0]; to get the first key. If you are expecting more keys, you can use

Object.keys(myVar).forEach(function(k) {
    if(k === "typeA") {
        // do stuff
    }
    else if (k === "typeB") {
        // do more stuff
    }
    else {
        // do something
    }
});

If you can't use any libraries to encode the value, http://www.urlencoder.org/ or http://www.urlencode-urldecode.com/ or ...

Just enter your value "M&M", not the full URL ;-)

x % n == 0
which means the x/n and the value of reminder will taken as a result and compare with zero....

example: 4/5==0

4/5 reminder is 4

4==0 (False)

Implementation with Guzzle library:

use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;

$httpClient = new Client();

$response = $httpClient->post(
    'https://postman-echo.com/post',
    [
        RequestOptions::BODY => 'POST raw request content',
        RequestOptions::HEADERS => [
            'Content-Type' => 'application/x-www-form-urlencoded',
        ],
    ]
);

echo(
    $response->getBody()->getContents()
);

PHP CURL extension:

$curlHandler = curl_init();

curl_setopt_array($curlHandler, [
    CURLOPT_URL => 'https://postman-echo.com/post',
    CURLOPT_RETURNTRANSFER => true,

    /**
     * Specify POST method
     */
    CURLOPT_POST => true,

    /**
     * Specify request content
     */
    CURLOPT_POSTFIELDS => 'POST raw request content',
]);

$response = curl_exec($curlHandler);

curl_close($curlHandler);

echo($response);

two of the best options are

$(this).parent("div:first")

$(this).parent().closest('div')

and of course you can find the class attr by

$(this).parent("div:first").attr("class")

$(this).parent().closest('div').attr("class")

sqlall just prints the SQL, it doesn't execute it. syncdb will create tables that aren't already created, but it won't modify existing tables.

check your xml file

Add "watch": "nodemon --exec ts-node -- ./src/index.ts" to scripts section of your package.json.

Remove spacing from b/w columns using bootstrap 3.7.7 or less.

.no-gutter is a custom class that you can add to your row DIVs

.no-gutter > [class*='col-'] {
        padding-right:0;
        padding-left:0;
    }

CHAR is a fixed length field; VARCHAR is a variable length field. If you are storing strings with a wildly variable length such as names, then use a VARCHAR, if the length is always the same, then use a CHAR because it is slightly more size-efficient, and also slightly faster.

This is an old thread, but I happened across it and I'm surprised nobody has put up a complete answer yet. So here goes...

The Executing a Command Line Script Tutorial!

Q: How do I execute this in Terminal?

Confusions and Conflicts:

• You do not need an 'extension' (like .sh or .py or anything else), but it helps to keep track of things. It won't hurt. If the script name contains an extension, however, you must use it.
• You do not need to be in any certain directory at all for any reason.
• You do not need to type out the name of the program that runs the file (BASH or Python or whatever) unless you want to. It won't hurt.
• You do not need sudo to do any of this. This command is reserved for running commands as another user or a 'root' (administrator) user. Great post here.

(A person who is just learning how to execute scripts should not be using this command unless there is a real need, like installing a new program. A good place to put your scripts is in your ~/bin folder. You can get there by typing cd ~/bin or cd $HOME/bin from the terminal prompt. You will have full permissions in that folder.)

To "execute this script" from the terminal on a Unix/Linux type system, you have to do three things:

1. Tell the system the location of the script. (pick one)

   • Type the full path with the script name (e.g. /path/to/script.sh). You can verify the full path by typing pwd or echo $PWD in the terminal.
   • Execute from the same directory and use ./ for the path (e.g. ./script.sh). Easy.
   • Place the script in a directory that is on the system PATH and just type the name (e.g. script.sh). You can verify the system PATH by typing echo $PATH or echo -e ${PATH//:/\\n} if you want a neater list.

2. Tell the system that the script has permission to execute. (pick one)

   • Set the "execute bit" by typing chmod +x /path/to/script.sh in the terminal.
   • You can also use chmod 755 /path/to/script.sh if you prefer numbers. There is a great discussion with a cool chart here.

3. Tell the system the type of script. (pick one)

   • Type the name of the program before the script. (e.g. BASH /path/to/script.sh or PHP /path/to/script.php) If the script has an extension, such as .php or .py, it is part of the script name and you must include it.
   • Use a shebang, which I see you have (#!/bin/bash) in your example. If you have that as the first line of your script, the system will use that program to execute the script. No need for typing programs or using extensions.
   • Use a "portable" shebang. You can also have the system choose the version of the program that is first in the PATH by using #!/usr/bin/env followed by the program name (e.g. #!/usr/bin/env bash or #!/usr/bin/env python3). There are pros and cons as thoroughly discussed here.

This should do the trick

export DEBIAN_FRONTEND=noninteractive
sudo -E apt-get -q -y install mysql-server

Of course, it leaves you with a blank root password - so you'll want to run something like

mysqladmin -u root password mysecretpasswordgoeshere

Afterwards to add a password to the account.

Git uses "the index" to prepare commits. You can add and remove changes from the index before you commit (in your paste you already have deleted ~10 files with git rm). When the index looks like you want it, run git commit.

Usually this will fire up vim. To insert text hit i, <esc> goes back to normal mode, hit ZZ to save and quit (ZQ to quit without saving). voilà, there's your commit

Comparison of strings is very easy in Ruby:

v1 = "string1"
v2 = "string2"
puts v1 == v2 # prints false
puts "hello"=="there" # prints false
v1 = "string2"
puts v1 == v2 # prints true

Make sure your var2 is not an array (which seems to be like)

You can access the full uri/url with 'document.referrer'

Check https://developer.mozilla.org/en-US/docs/Web/API/Document/referrer

I suspect you are running Android 6.0 Marshmallow (API 23) or later. If this is the case, you must implement runtime permissions before you try to read/write external storage.

There are two options for this problem.

1) git rebase

2) git merge

Only diff with above both in case of merge, will have extra commit in history

1) git checkout branch(b1,b2,b3)

2) git rebase origin/master (In case of conflicts resolve locally by doing git rebase --continue)

3) git push

Alternatively, git merge option is similar fashion

1) git checkout "your_branch"(b1,b2,b3)

2) git merge master

3) git push

SELECT DISTINCT   
                 CONVERT(VARCHAR(17), A.SOURCE_DEPARTURE_TIME, 108)  
FROM  
      CONSOLIDATED_LIST AS A  
WHERE   
      CONVERT(VARCHAR(17), A.SOURCE_DEPARTURE_TIME, 108) BETWEEN '15:00:00' AND '15:45:00'

h2.text-left{
  position:relative;
  top:50%;
  transform: translateY(-50%);
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
}

Explanation:

The top:50% style essentially pushes the header element down 50% from the top of the parent element. The translateY stylings also act in a similar manner by moving then element down 50% from the top.

Please note that this works well for headers with 1 (maybe 2) lines of text as this simply moves the top of the header element down 50% and then the rest of the content fills in below that, which means that with multiple lines of text it would appear to be slightly below vertically aligned.

A possible fix for multiple lines would be to use a percentage slightly less than 50%.

when you create an object using predefine class, at first you want to create a variable for storing that object. Then you can create object and store variable that you created.

class Student:
     def __init__(self):

# creating an object....

   student1=Student()

Actually this init method is the constructor of class.you can initialize that method using some attributes.. In that point , when you creating an object , you will have to pass some values for particular attributes..

class Student:
      def __init__(self,name,age):
            self.name=value
            self.age=value

 # creating an object.......

     student2=Student("smith",25)

Provide the Directory/Folder path where python.exe is available in Anaconda folder like

C:\Users\user_name\Anaconda3\

This should must work.

Another option is to left join your Results table with your existing competitors Table and find the new competitors by filtering the distinct records that don´t match int the join:

INSERT Competitors (cName)
SELECT  DISTINCT cr.Name
FROM    CompResults cr left join
        Competitors c on cr.Name = c.cName
where   c.cName is null

New syntax MERGE also offer a compact, elegant and efficient way to do that:

MERGE INTO Competitors AS Target
USING (SELECT DISTINCT Name FROM CompResults) AS Source ON Target.Name = Source.Name
WHEN NOT MATCHED THEN
    INSERT (Name) VALUES (Source.Name);

do you mean like so:

DateTime datetime = new DateTime();

if (datetime == DateTime.MinValue)
{
    //unassigned
}

or you could use Nullable

DateTime? datetime = null;

 if (!datetime.HasValue)
 {
     //unassigned
 }

Its even good to use tortoise svn cleanup, no need to use Ankh one in my case

The best way to do this is actually just use <%= form_authenticity_token.to_s %> to print out the token directly in your rails code. You dont need to use javascript to search the dom for the csrf token as other posts mention. just add the headers option as below;

$.ajax({
  type: 'post',
  data: $(this).sortable('serialize'),
  headers: {
    'X-CSRF-Token': '<%= form_authenticity_token.to_s %>'
  },
  complete: function(request){},
  url: "<%= sort_widget_images_path(@widget) %>"
})

I ran into this issue today. Here is my hacky solution.

I needed a fixed position element to transition up by 100 pixels as it loaded.

var delay = (ms) => new Promise(res => setTimeout(res, ms));
async function animateView(startPosition,elm){
  for(var i=0; i<101; i++){
    elm.style.top = `${(startPosition-i)}px`;
    await delay(1);
  }
}

Is it pausing, but you don't see your red color appear in the cell? Try this:

dataGridView1.Rows[x1].Cells[y1].Style.BackColor = System.Drawing.Color.Red;
dataGridView1.Refresh();
System.Threading.Thread.Sleep(1000);

From this documentation

pandas provides a single function, merge, as the entry point for all standard database join operations between DataFrame objects:

merge(left, right, how='inner', on=None, left_on=None, right_on=None,
      left_index=False, right_index=False, sort=True,
      suffixes=('_x', '_y'), copy=True, indicator=False)

And :

DataFrame.join is a convenient method for combining the columns of two potentially differently-indexed DataFrames into a single result DataFrame. Here is a very basic example: The data alignment here is on the indexes (row labels). This same behavior can be achieved using merge plus additional arguments instructing it to use the indexes:

result = pd.merge(left, right, left_index=True, right_index=True,
how='outer')
