This is called string interpolation; it doesn't exist as such in Java.

One approach is to use String.format:

String string = String.format("A string %s", aVariable);

Another approach is to use a templating library such as Velocity or FreeMarker.

REASON

This happens because for now they only ship 64bit JRE with Android Studio for Windows which produces glitches in 32 bit systems.

SOLUTION

• do not use the embedded JDK: Go to File -> Project Structure dialog, uncheck "Use embedded JDK" and select the 32-bit JRE you've installed separately in your system
• decrease the memory footprint for Gradle in gradle.properties(Project Properties), for eg set it to -Xmx768m.

For more details: https://code.google.com/p/android/issues/detail?id=219524

You have several options to set up variables from outside your makefile:

• From environment - each environment variable is transformed into a makefile variable with the same name and value.

  You may also want to set -e option (aka --environments-override) on, and your environment variables will override assignments made into makefile (unless these assignments themselves use the override directive . However, it's not recommended, and it's much better and flexible to use ?= assignment (the conditional variable assignment operator, it only has an effect if the variable is not yet defined):

  FOO?=default_value_if_not_set_in_environment
  

  Note that certain variables are not inherited from environment:

  • MAKE is gotten from name of the script
  • SHELL is either set within a makefile, or defaults to /bin/sh (rationale: commands are specified within the makefile, and they're shell-specific).

• From command line - make can take variable assignments as part of his command line, mingled with targets:

  make target FOO=bar
  

  But then all assignments to FOO variable within the makefile will be ignored unless you use the override directive in assignment. (The effect is the same as with -e option for environment variables).

• Exporting from the parent Make - if you call Make from a Makefile, you usually shouldn't explicitly write variable assignments like this:

  # Don't do this!
  target:
          $(MAKE) -C target CC=$(CC) CFLAGS=$(CFLAGS)
  

  Instead, better solution might be to export these variables. Exporting a variable makes it into the environment of every shell invocation, and Make calls from these commands pick these environment variable as specified above.

  # Do like this
  CFLAGS=-g
  export CFLAGS
  target:
          $(MAKE) -C target
  

  You can also export all variables by using export without arguments.

Run the code either in onload event, either just before you close body tag. You try to find an element wich is not there at the moment you do it.

<?php

$xml = $argv[1];

$dom = new DOMDocument();

// Initial block (must before load xml string)
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
// End initial block

$dom->loadXML($xml);
$out = $dom->saveXML();

print_R($out);

Found the solution as below.... posting it as it could help somebody else too :)

DateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
Date date = format.parse("2014-04-24 11:15:00");

GregorianCalendar cal = new GregorianCalendar();
cal.setTime(date);

XMLGregorianCalendar xmlGregCal =  DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);

System.out.println(xmlGregCal);

Output:

2014-04-24T11:15:00.000+02:00

$("#birthdate" ).datepicker("setDate", new Date(1985,01,01))

I've opted for a quick Polyfill based on the above answers:

//# Polyfill
window.addEventListener = window.addEventListener || function (e, f) { window.attachEvent('on' + e, f); };

//# Standard usage
window.addEventListener("message", function(){ /*...*/ }, false);

Of course, like the answers above this doesn't ensure that window.attachEvent exists, which may or may not be an issue.

Jeff Gilfelt's answer as a static helper method:

private static String getSizeName(Context context) {
    int screenLayout = context.getResources().getConfiguration().screenLayout;
    screenLayout &= Configuration.SCREENLAYOUT_SIZE_MASK;

    switch (screenLayout) {
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        return "small";
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        return "normal";
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        return "large";
    case 4: // Configuration.SCREENLAYOUT_SIZE_XLARGE is API >= 9
        return "xlarge";
    default:
        return "undefined";
    }
}

step 1 : create layout with name activity_main.xml

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/rl"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    tools:context=".MainActivity"
    android:background="#c6cabd"
    >
    <TextView
        android:id="@+id/tv"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="17dp"
        android:textColor="#ff0e13"
        />
    <EditText
        android:id="@+id/et"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/tv"
        android:hint="Input your country"
        />
    <Button
        android:id="@+id/btn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Get EditText Text"
        android:layout_below="@id/et"
        />
</RelativeLayout>

Step 2 : Create class Main.class

public class Main extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button btn = (Button) findViewById(R.id.btn);
        final TextView tv = (TextView) findViewById(R.id.tv);
        final EditText et = (EditText) findViewById(R.id.et);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                String country = et.getText().toString();
                tv.setText("Your inputted country is : " + country);
            }
        });
 }
}

Try this code

var path: String = NSBundle.mainBundle().pathForResource("nameOfFile", ofType: "svg")!

        var url: NSURL = NSURL.fileURLWithPath(path)  //Creating a URL which points towards our path

       //Creating a page request which will load our URL (Which points to our path)
        var request: NSURLRequest = NSURLRequest(URL: url)
       webView.loadRequest(request)  //Telling our webView to load our above request

METHOD 1 ( Recommanded )

Library YouTubeExtractor

Add into your gradle file

 allprojects {
        repositories {
            maven { url "https://jitpack.io" }
        }
    }

And dependencies

 compile 'com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'

Add this small code and you done. Demo HERE

public class MainActivity extends AppCompatActivity {

    private static final String YOUTUBE_ID = "ea4-5mrpGfE";

    private final YouTubeExtractor mExtractor = YouTubeExtractor.create();


    private Callback<YouTubeExtractionResult> mExtractionCallback = new Callback<YouTubeExtractionResult>() {
        @Override
        public void onResponse(Call<YouTubeExtractionResult> call, Response<YouTubeExtractionResult> response) {
            bindVideoResult(response.body());
        }

        @Override
        public void onFailure(Call<YouTubeExtractionResult> call, Throwable t) {
            onError(t);
        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


//        For android youtube extractor library  com.github.Commit451.YouTubeExtractor:youtubeextractor:2.1.0'
        mExtractor.extract(YOUTUBE_ID).enqueue(mExtractionCallback);

    }


    private void onError(Throwable t) {
        t.printStackTrace();
        Toast.makeText(MainActivity.this, "It failed to extract. So sad", Toast.LENGTH_SHORT).show();
    }


    private void bindVideoResult(YouTubeExtractionResult result) {

//        Here you can get download url link
        Log.d("OnSuccess", "Got a result with the best url: " + result.getBestAvailableQualityVideoUri());

        Toast.makeText(this, "result : " + result.getSd360VideoUri(), Toast.LENGTH_SHORT).show();
    }
}

You can get download link in bindVideoResult() method.

       String youtubeLink = "http://youtube.com/watch?v=xxxx";

    YouTubeUriExtractor ytEx = new YouTubeUriExtractor(this) {
        @Override
        public void onUrisAvailable(String videoId, String videoTitle, SparseArray<YtFile> ytFiles) {
            if (ytFiles != null) {
                int itag = 22;
// Here you can get download url
                String downloadUrl = ytFiles.get(itag).getUrl();
            }
        }
    };

    ytEx.execute(youtubeLink);

This question has been asked and answered many times:

Read file from serial port using Java

Reading serial port in Java

Reading file from serial port in Java

Is there Java library or framework for accessing Serial ports?

Java Serial Communication on Windows

to reference a few.

Personally I recommend SerialPort from http://serialio.com - it's not free, but it's well worth the developer (no royalties) licensing fee for any commercial project. Sadly, it is no longer royalty free to deploy, and SerialIO.com seems to have remade themselves as a hardware seller; I had to search for information on SerialPort.

From personal experience, I strongly recommend against the Sun, IBM and RxTx implementations, all of which were unstable in 24/7 use. Refer to my answers on some of the aforementioned questions for details. To be perfectly fair, RxTx may have come a long way since I tried it, though the Sun and IBM implementations were essentially abandoned, even back then.

A newer free option that looks promising and may be worth trying is jSSC (Java Simple Serial Connector), as suggested by @Jodes comment.

Short tag are alwayes available in php. So you do not need echo the first statement in your script

example:

    $a =10;
    <?= $a;//10 
    echo "Hellow";//
    echo "Hellow";

   ?>

Suddenly you need to use for a single php script then u can use it. example:

<html>
<head>
<title></title>
</head>  
<body>
<p>hellow everybody<?= hi;?></p>
<p>hellow everybody  </p> 
<p>hellow everybody  </p>   
</body>
</html>

Or you can skip rake and use the 'rspec' command:

rspec path/to/spec/file.rb

In your case I think as long as your ./spec/db_spec.rb file includes the appropriate helpers, it should work fine.

If you're using an older version of rspec it is:

spec path/to/spec/file.rb

By using ''.join

list1 = ['1', '2', '3']
str1 = ''.join(list1)

Or if the list is of integers, convert the elements before joining them.

list1 = [1, 2, 3]
str1 = ''.join(str(e) for e in list1)

Do not use Class.newInstance(); see this thread: Why is Class.newInstance() evil?

Like other answers say, use Constructor.newInstance() instead.

I had the pleasure of experiencing this random problem in Visual Studio 2017 Enterprise.

I tried every solution here, and it didn't work, including the Visual Studio repair (which takes a while). Several hours in, I thought maybe I should actually check the ActivityLog.xml file.

I uninstalled the offending extension from the 'Developer Command Prompt for VS2017' as an administrator since Visual Studio just freezed after open and nothing could be clicked.

Steps to uninstall - courtesy of jessehouwing.net

1. Find the vsix file you used to install the extension.
2. Open it in your favorite archiver (mine is 7-Zip).
3. Grab the extension's Id from the Identity node from the extension.vsixmanifest.
4. Run (in my case) vsixinstaller /u:Microsoft.VisualStudio.LiveShare to remove the extension.

If you are using qmake, the standard Qt build system, just add a line to the .pro file as documented in the qmake Variable Reference:

INCLUDEPATH += <your path>

If you are using your own build system, you create a project by selecting "Import of Makefile-based project". This will create some files in your project directory including a file named <your project name>.includes. In that file, simply list the paths you want to include, one per line. Really all this does is tell Qt Creator where to look for files to index for auto completion. Your own build system will have to handle the include paths in its own way.

As explained in the Qt Creator Manual, <your path> must be an absolute path, but you can avoid OS-, host- or user-specific entries in your .pro file by using $$PWD which refers to the folder that contains your .pro file, e.g.

INCLUDEPATH += $$PWD/code/include

You have no need to put for loop to see the data into the array, you can simply do in following manner

<?php
echo "<pre>";
 print_r($results); 
echo "</pre>";
?>

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

aspose pdf works pretty well. then again, you have to pay for it

Since Ubuntu 16.04 includes snapd by default.
So, the easiest way to install the stable version is

• IntelliJ IDEA Community:
  $ sudo snap install intellij-idea-community --classic
• IntelliJ IDEA Ultimate:
  $ sudo snap install intellij-idea-ultimate --classic

For the latest version use channel --edge
$ sudo snap install intellij-idea-community --classic --edge

Here is the list of all channels https://snapcraft.io/intellij-idea-ultimate (drop down 'All versions').

options

--classic

The --classic option is required because the IntelliJ IDEA snap requires full access to the system, like a traditionally packaged application.
[https://www.jetbrains.com/help/idea/install-and-set-up-product.html#install-on-linux-with-snaps]

--edge

--edge Install from the edge channel [http://manpages.ubuntu.com/manpages/bionic/man1/snap.1.html]

Note: Snap, also work a few major distributions: Arch, Debian, Fedora, openSUSE, Linux Mint,...

In R you can use the refresh method, but to start with we navigate to a url using navigate method:

remDr$navigate("https://...")
remDr$refresh()

Java is only pass-by-value. (or better - pass-reference-by-value)

So the passed argument and the argument within the method are two different handlers pointing to the same object (value).

Therefore if you change the state of the object, it is reflected to every other variable that's referencing it. But if you re-assign a new object (value) to the argument, then other variables pointing to this object (value) do not get re-assigned.

You can do both in code and XML. Only 4 basic things to be set.

1. shadow color
2. Shadow Dx - it specifies the X-axis offset of shadow. You can give -/+ values, where -Dx draws a shadow on the left of text and +Dx on the right
3. shadow Dy - it specifies the Y-axis offset of shadow. -Dy specifies a shadow above the text and +Dy specifies below the text.
4. shadow radius - specifies how much the shadow should be blurred at the edges. Provide a small value if shadow needs to be prominent. Else otherwise.

e.g.

    android:shadowColor="@color/text_shadow_color"
    android:shadowDx="-2"
    android:shadowDy="2"
    android:shadowRadius="0.01"

This draws a prominent shadow on left-lower side of text. In code, you can add something like this;

    TextView item = new TextView(getApplicationContext());
    item.setText(R.string.text);
    item.setTextColor(getResources().getColor(R.color.general_text_color));
    item.setShadowLayer(0.01f, -2, 2,   getResources().getColor(R.color.text_shadow_color));

Use is_int($var)

Here is tutorial about is_int()

You can use Data::Dump:

use Data::Dump qw(dump);
my @a = (1, [2, 3], {4 => 5});
dump(@a);

Produces:

"(1, [2, 3], { 4 => 5 })"

The algorithm has 4 simple steps:

1. Divide the array into 3 different parts: left, pivot and right, where pivot will have only one element. Let us choose this pivot element as the first element of array
2. Append elements to the respective part by comparing them to pivot element. (explanation in comments)
3. Recurse this algorithm till all elements in the array have been sorted
4. Finally, join left+pivot+right parts

Code for the algorithm in python:

def my_sort(A):

      p=A[0]                                       #determine pivot element. 
      left=[]                                      #create left array
      right=[]                                     #create right array
      for i in range(1,len(A)):
        #if cur elem is less than pivot, add elem in left array
        if A[i]< p:
          left.append(A[i])         
          #the recurssion will occur only if the left array is atleast half the size of original array
          if len(left)>1 and len(left)>=len(A)//2:          
              left=my_sort(left)                            #recursive call
        elif A[i]>p: 
          right.append(A[i])                                #if elem is greater than pivot, append it to right array
          if len(right)>1 and len(right)>=len(A)//2:        # recurssion will occur only if length of right array is atleast the size of original array
              right=my_sort(right)
     A=left+[p]+right                                        #append all three part of the array into one and return it
     return A

my_sort([12,4,5,6,7,3,1,15])

Carry on with this algorithm recursively with the left and right parts.

Bootstrap 3 dropped native support for nested collapsing menus, but there's a way to re-enable it with a 3rd party script. It's called SmartMenus. It means adding three new resources to your page, but it seamlessly supports Bootstrap 3.x with multiple levels of menus for nested <ul>/<li> elements with class="dropdown-menu". It automatically displays the proper caret indicator as well.

<head>
   ...
   <script src=".../jquery.smartmenus.min.js"></script>
   <script src=".../jquery.smartmenus.bootstrap.min.js"></script>
   ...
   <link rel="stylesheet" href=".../jquery.smartmenus.bootstrap.min.css"/>
   ...
</head>

Here's a demo page: http://vadikom.github.io/smartmenus/src/demo/bootstrap-navbar-fixed-top.html

def rotate(image, angle, center = None, scale = 1.0):
    (h, w) = image.shape[:2]

    if center is None:
        center = (w / 2, h / 2)

    # Perform the rotation
    M = cv2.getRotationMatrix2D(center, angle, scale)
    rotated = cv2.warpAffine(image, M, (w, h))

    return rotated

I had this issue when inserting date data into a database, you can simply use the struct members separately: In my case it's useful since the sql sentence needs to have the right values and you just need to add the slash or dash to complete the format, no conversions needed.

DateTimePicker dtp = new DateTimePicker();
String sql = "insert into table values(" + dtp.Value.Date.Year + "/" + 
dtp.Value.Date.Month + "/" + dtp.Value.Date.Day + ");";

That way you get just the date members without time...

First CD to where node(nodejs) is installed using windows CMD, then follow the steps below

C:...\node> git config --system http.sslcainfo /bin/curl-ca-bundle.crt
C:...\node> git clone --recursive git://github.com/isaacs/npm.git
C:...\node> cd node=modules\npm
C:...\node=modules\npm> node cli.js install npm -gf

If you want a CompletableFuture way you could have a method like

public MyResponseObject retrieveDataFromEndpoint() {

   CompletableFuture<MyResponseObject> endpointCall 
       = CompletableFuture.supplyAsync(() ->
             yourRestService.callEnpoint(withArg1, withArg2));

   try {
       return endpointCall.get(10, TimeUnit.MINUTES);
   } catch (TimeoutException 
               | InterruptedException 
               | ExecutionException e) {
       throw new RuntimeException("Unable to fetch data", e);
   }
}

If you're using spring, you could annotate the method with a @Retryable so that it retries the method three times if an exception is thrown.

This will allow a space between the two columns and obviously if you want to change the default width you can go for mixins to modify the default bootstrap width. Or, you can give the width using the inline CSS style.

<div class="col-md-5 pull-left"></div>
<div class="col-md-5 pull-right"></div>

Python 3.3+ has Implicit Namespace Packages that allow it to create a packages without an __init__.py file.

Allowing implicit namespace packages means that the requirement to provide an __init__.py file can be dropped completely, and affected ... .

The old way with __init__.py files still works as in Python 2.

a is the array of objects you have

a.findIndex(x => x.property=="WhateverPropertyYouWantToMatch") <0 ? 
a.push(objectYouWantToPush) : console.log("response if object exists");

Another approach using RegExp

const list = [1, 2, 3, 5, 2, 8, 9, 2]
const d = 2;
const counter = (`${list.join()},`.match(new RegExp(`${d}\\,`, 'g')) || []).length

console.log(counter)

The Steps follows as below

1. Join the string using a comma Remember to append ',' after joining so as not to have incorrect values when value to be matched is at the end of the array
2. Match the number of occurrence of a combination between the digit and comma
3. Get length of matched items

If using PostgreSql 9.5.1, please follow the below configuration:

1. Open hg_hba.conf in pgAdmin
2. Select your path, and open it, then add a setting
3. Restart postgresql service

You can't move a mouse but can lock it. Note: that you must call requestPointerLock in click event.

Small Example:

var canvas = document.getElementById('mycanvas');
canvas.requestPointerLock = canvas.requestPointerLock || canvas.mozRequestPointerLock || canvas.webkitRequestPointerLock;
canvas.requestPointerLock();

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.

You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.

1. Save the file with another name like 'dosbox-0.74original.conf' to preserve the original file in case you need to restore it.
2. Search on 'resolution' and carefully read what the conf file says about changing it. There are essentially two variables: resolution and output. You want to leave fullresolution alone for now. Your question was about WINDOW, not full. So look for windowresolution, see what the comments in conf file say you can do. The best suggestion is to use a bigger-window resolution like 900x800 (which is what I used on a 1366x768 screen), but NOT the actual resolution of your machine (which would make the window fullscreen, and you said you didn't want that). Be specific, replacing the 'windowresolution=original' with 'windowresolution=900x800' or other dimensions. On my screen, that doubled the window size just as it does with the max Font tab in Windows Properties (for the exe file; as you'll see below the ==== marks, 32-bit Windows doesn't need Dosbox).

Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).

So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.

Yes, the Map constructor takes an array of key-value pairs.

Object.entries is a new Object static method available in ES2017 (19.1.2.5).

const map = new Map(Object.entries({foo: 'bar'}));

map.get('foo'); // 'bar'

It's currently implemented in Firefox 46+ and Edge 14+ and newer versions of Chrome

If you need to support older environments and transpilation is not an option for you, use a polyfill, such as the one recommended by georg:

Object.entries = typeof Object.entries === 'function' ? Object.entries : obj => Object.keys(obj).map(k => [k, obj[k]]);

Try this. Click anywhere in your range of data and then use this macro:

Sub CombineColumns()
Dim rng As Range
Dim iCol As Integer
Dim lastCell As Integer

Set rng = ActiveCell.CurrentRegion
lastCell = rng.Columns(1).Rows.Count + 1

For iCol = 2 To rng.Columns.Count
    Range(Cells(1, iCol), Cells(rng.Columns(iCol).Rows.Count, iCol)).Cut
    ActiveSheet.Paste Destination:=Cells(lastCell, 1)
    lastCell = lastCell + rng.Columns(iCol).Rows.Count
Next iCol
End Sub

I have encountered similar (nearly unexplainable) behavior

Found a reference to deleting .exd files under the directory C:\Users\username\AppData\Local\Temp Located one in each of the directory Excel8.0 and VBE. Typical name is MSForms.exd

Google "Excel exd" or "KB 2553154" From my perspective, it is a completely unacceptable situation which has been there for at least a month now.

You can use android:background="#DC143C", or any other RGB values for your color. I have no problem using it this way, as stated here

If you have a SOAPMessage or SOAPMessageContext, you can use a Transformer, by converting it to a Source via DOMSource:

            final SOAPMessage message = messageContext.getMessage();
            final StringWriter sw = new StringWriter();

            try {
                TransformerFactory.newInstance().newTransformer().transform(
                    new DOMSource(message.getSOAPPart()),
                    new StreamResult(sw));
            } catch (TransformerException e) {
                throw new RuntimeException(e);
            }

            // Now you have the XML as a String:
            System.out.println(sw.toString());

This will take the encoding into account, so your "special characters" won't get mangled.

You can use this code instead.

<div id="" style="overflow-y:scroll; overflow-x:hidden; height:400px;">

overflow-x: The overflow-x property specifies what to do with the left/right edges of the content - if it overflows the element's content area.
overflow-y: The overflow-y property specifies what to do with the top/bottom edges of the content - if it overflows the element's content area.

Values
visible: Default value. The content is not clipped, and it may be rendered outside the content box.
hidden: The content is clipped - and no scrolling mechanism is provided.
scroll: The content is clipped and a scrolling mechanism is provided.
auto: Should cause a scrolling mechanism to be provided for overflowing boxes.
initial: Sets this property to its default value.
inherit Inherits this property from its parent element.

I know the op was using an older version of IIS and this may not apply to him, but I'm posting this as it might help others. I had the same problem and none of the above IPv6 or hosts file changes worked for me. My asp.net MVC4 project was really slow after hitting F5 to refresh js changes on localhost. It was happening across all browsers - Chrome, FF, and IE. Eventually I realised I was running IIS Express 8.0 locally, and it turns out 8.0 is extremely slow when serving up js files and seems to be a bug. If I ran iisexpress on the command line and hit F5 I could see each js file took 4 or 5 seconds to load.

I ended up uninstalling IIS 8.0 and installing IIS express 7.5 and straight away the problem was fixed. Here are the steps I followed:

• Uninstall IIS express 8.0
• Delete the IISExpress folder (on Win 7 it's in My Documents\IISExpress)
• Install IIS express 7.5 (Link to IIS Express 7.5 download)

IIS Express 8.0 seems to be installed with VS 2012 so if you had a new install or possibly a service pack update this might upgrade the previous IIS Express version.

In Windows 7, 8 or 8.1, in Devices Manager:

1. Select tree 'Android Device': remove 'Android Composite ADB Interface' [?]
2. Press on main root of devices tree and call context menu (by right mouse click) and click on 'Update configuration'
3. After updating your device should appear in 'Other devices'
4. Select your device, call context menu from it and choose 'Update driver' and perform this updating

You can execute this statement in the mysql command line tool:

echo "SELECT concat('ALTER TABLE `',TABLE_NAME,'` ENGINE=InnoDB;')
FROM Information_schema.TABLES 
WHERE ENGINE != 'InnoDB' AND TABLE_TYPE='BASE TABLE' 
AND TABLE_SCHEMA='name-of-database'" | mysql > convert.sql

You may need to specify username and password using: mysql -u username -p The result is an sql script that you can pipe back into mysql:

mysql name-of-database < convert.sql

Replace "name-of-database" in the above statement and command line.

You can to do it this way:

string Camnr = "", Klantnr = "", ... // or String.Empty

Or you could declare them all first and then in the next line use your way.

This is an old question, but I'm going to add the fix for my particular issue (Spring Boot, JPA using Hibernate, SQL Server 2014) since it doesn't exactly match the other answers included here:

I had a foreign key, e.g. my_id = '12345', but the value in the referenced column was my_id = '12345 '. It had an extra space at the end which hibernate didn't like. I removed the space, fixed the part of my code that was allowing this extra space, and everything works fine.

Note that -regex depends on whole path.

 -regex pattern
              File name matches regular expression pattern.  
              This is a match on the whole path, not a search.

You don't actually have to use -regex for what you are doing.

find . -iname "*[0-9]"

I don't know anything provided by the Framework (beyond what you want to avoid) that would do what you want but (as I suspect you know) it would be pretty easy to create something simple yourself:

private DataTable GetDataTableFromDGV(DataGridView dgv) {
    var dt = new DataTable();
    foreach (DataGridViewColumn column in dgv.Columns) {
        if (column.Visible) {
            // You could potentially name the column based on the DGV column name (beware of dupes)
            // or assign a type based on the data type of the data bound to this DGV column.
            dt.Columns.Add();
        }
    }

    object[] cellValues = new object[dgv.Columns.Count];
    foreach (DataGridViewRow row in dgv.Rows) {
        for (int i = 0; i < row.Cells.Count; i++) {
            cellValues[i] = row.Cells[i].Value;
        }
        dt.Rows.Add(cellValues);
    }

    return dt;
}

Select 3000 random records in Netezza:

WITH IDS AS (
     SELECT ID
     FROM MYTABLE;
)

SELECT ID FROM IDS ORDER BY mt_random() LIMIT 3000

If you are inserting keys that are comparable but not int-like, you could potentially override the comparison operators on them (i.e. <= become > and > becomes <=). Otherwise, you can override heapq._siftup in the heapq module (it's all just Python code, in the end).

I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes

public function scopeWhereLike($query, $column, $value)
{
    return $query->where($column, 'like', '%'.$value.'%');
}

public function scopeOrWhereLike($query, $column, $value)
{
    return $query->orWhere($column, 'like', '%'.$value.'%');
}

Usage:

$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();

The parseInt solution is the best way to go as it is clear what is happening.

For completeness it is worth mentioning that this can also be done with the + operator

$('.load_more').live("click",function() { //When user clicks
  var newcurrentpageTemp = +$(this).attr("id") + 1; //Get the id from the hyperlink
  alert(newcurrentpageTemp);
  dosomething();
});

In my case problem was in css and html layout. Layout was something like html - body - root - ... html and body was overflow: hidden, and root was position: fixed, height: 100vh.

Whith this layout browser tabs on mobile doesnt hide. For solve this I delete overflow: hidden from html and body and delete position: fixed, height: 100vh from root.

select substring(substring('B10000N0Z', patindex('%[0]%','B10000N0Z'), 20), 
    patindex('%[^0]%',substring('B10000N0Z', patindex('%[0]%','B10000N0Z'), 
    20)), 20)

returns N0Z, that is, will get rid of leading zeroes and anything that comes before them.

You don't need to escape the ' character in a String (wrapped in "), and you don't have to escape a " character in a char (wrapped in ').

You can use toLocaleString(). This is a javascript method.

var event = new Date("01/02/1993");_x000D_
_x000D_
var options = { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' };_x000D_
_x000D_
console.log(event.toLocaleString('en', options));_x000D_
_x000D_
// expected output: "Saturday, January 2, 1993"

Almost all formats supported. Have look on this link for more details.

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleString

Returns true if comes 'y', '1', 'true', 'on'or whatever you add in similar way

boolean getValue(String value) {
  return ("Y".equals(value.toUpperCase()) 
      || "1".equals(value.toUpperCase())
      || "TRUE".equals(value.toUpperCase())
      || "ON".equals(value.toUpperCase()) 
     );
}

Seems bundler can't use .gem files out of the box. Pointing the :path to a directory containing .gem files doesn't work. Some people suggested to setup a local gem server (geminabox, stickler) for that purpose.

However, what I found to be much simpler is to use a local gem "server" from file system: Just put your .gem files in a local directory, then use "gem generate_index" to make it a Gem repository

mkdir repo
mkdir repo/gems
cp *.gem repo/gems
cd repo
gem generate_index

Finally point bundler to this location by adding the following line to your Gemfile

source "file://path/to/repo"

If you update the gems in the repository, make sure to regenerate the index.

I had my tryst with KSOAP; I chose a rather simpler approach.

Given a WSDL file, create SOAP Request templates for each Request(for e.g.: using SOAP UI) and then substitute the values to be passed in code. POST this data to the service end point using DefaultHttpClient instance and get the response stream. Parse the Response Stream using an XML Pull parser.

I found an excellent utility that is configurable at https://github.com/acch/genfiles.

It fills the target file with random data, so there are no problems with sparse files, and for my purposes (testing compression algorithms) it gives a nice level of white noise.

PyPI packages not in the standard library:

• virtualenv is a very popular tool that creates isolated Python environments for Python libraries. If you're not familiar with this tool, I highly recommend learning it, as it is a very useful tool, and I'll be making comparisons to it for the rest of this answer.

  It works by installing a bunch of files in a directory (eg: env/), and then modifying the PATH environment variable to prefix it with a custom bin directory (eg: env/bin/). An exact copy of the python or python3 binary is placed in this directory, but Python is programmed to look for libraries relative to its path first, in the environment directory. It's not part of Python's standard library, but is officially blessed by the PyPA (Python Packaging Authority). Once activated, you can install packages in the virtual environment using pip.

• pyenv is used to isolate Python versions. For example, you may want to test your code against Python 2.7, 3.6, 3.7 and 3.8, so you'll need a way to switch between them. Once activated, it prefixes the PATH environment variable with ~/.pyenv/shims, where there are special files matching the Python commands (python, pip). These are not copies of the Python-shipped commands; they are special scripts that decide on the fly which version of Python to run based on the PYENV_VERSION environment variable, or the .python-version file, or the ~/.pyenv/version file. pyenv also makes the process of downloading and installing multiple Python versions easier, using the command pyenv install.

• pyenv-virtualenv is a plugin for pyenv by the same author as pyenv, to allow you to use pyenv and virtualenv at the same time conveniently. However, if you're using Python 3.3 or later, pyenv-virtualenv will try to run python -m venv if it is available, instead of virtualenv. You can use virtualenv and pyenv together without pyenv-virtualenv, if you don't want the convenience features.

• virtualenvwrapper is a set of extensions to virtualenv (see docs). It gives you commands like mkvirtualenv, lssitepackages, and especially workon for switching between different virtualenv directories. This tool is especially useful if you want multiple virtualenv directories.

• pyenv-virtualenvwrapper is a plugin for pyenv by the same author as pyenv, to conveniently integrate virtualenvwrapper into pyenv.

• pipenv aims to combine Pipfile, pip and virtualenv into one command on the command-line. The virtualenv directory typically gets placed in ~/.local/share/virtualenvs/XXX, with XXX being a hash of the path of the project directory. This is different from virtualenv, where the directory is typically in the current working directory. pipenv is meant to be used when developing Python applications (as opposed to libraries). There are alternatives to pipenv, such as poetry, which I won't list here since this question is only about the packages that are similarly named.

Standard library:

• pyvenv is a script shipped with Python 3 but deprecated in Python 3.6 as it had problems (not to mention the confusing name). In Python 3.6+, the exact equivalent is python3 -m venv.

• venv is a package shipped with Python 3, which you can run using python3 -m venv (although for some reason some distros separate it out into a separate distro package, such as python3-venv on Ubuntu/Debian). It serves the same purpose as virtualenv, but only has a subset of its features (see a comparison here). virtualenv continues to be more popular than venv, especially since the former supports both Python 2 and 3.

Recommendation for beginners:

This is my personal recommendation for beginners: start by learning virtualenv and pip, tools which work with both Python 2 and 3 and in a variety of situations, and pick up other tools once you start needing them.

There are security flaws to using preg_replace(), if you get the payload from user input [or other untrusted sources]. PHP executes the regular expression with eval(). If the incoming string isn't properly sanitized, your application risks being subjected to code injection.

In my own application, instead of bothering sanitizing the input (and as I only deal with short strings), I instead made a slightly more processor intensive function, though which is secure, since it doesn't eval() anything.

function secureRip(string $str): string { /* Rips all whitespace securely. */
  $arr = str_split($str, 1);
  $retStr = '';
  foreach ($arr as $char) {
    $retStr .= trim($char);
  }
  return $retStr;
}

Now, sometimes you already have less open, and you can't use cat on it. For example, you did a | less, and you can't just reopen a file, as that's actually a stream.

If all you need is to identify end of line, one easy way is to search for the last character on the line: /.$. The search will highlight the last character, even if it is a blank, making it easy to identify it.

That will only help with the end of line case. If you need other special characters, you can use the cat -vet solution above with marks and pipe:

• mark the top of the text you're interested in: ma
• go to the bottom of the text you're interested in and mark it, as well: mb
• go back to the mark a: 'a
• pipe from a to b through cat -vet and view the result in another less command: |bcat -vet | less

This will open another less process, which shows the result of running cat -vet on the text that lies between marks a and b.

If you want the whole thing, instead, do g|$cat -vet | less, to go to the first line and filter all lines through cat.

The advantage of this method over less options is that it does not mess with the output you see on the screen.

One would think that eight years after this question was originally posted, less would have that feature... But I can't even see a feature request for it on https://github.com/gwsw/less/issues

str.match(pattern), if pattern has the global flag g, will return all the matches as an array.

For example:

const str = 'All of us except @Emran, @Raju and @Noman was there';_x000D_
console.log(_x000D_
  str.match(/@\w*/g)_x000D_
);_x000D_
// Will log ["@Emran", "@Raju", "@Noman"]

used a reference like "///<reference path="web.ts" /> and then in the VS2013 project properties for building "app.ts","Typescript Build"->"Combine javascript output into file:"(checked)->"app.js"

If for some people (like me earlier) the above answers don't work, I think the following answer would work (for Mac users I think) Enter the following commands to do flask run

$ export FLASK_APP = hello.py
$ export FLASK_ENV = development
$ flask run

Alternatively you can do the following (I haven't tried this but one resource online talks about it)

$ export FLASK_APP = hello.py
$ python -m flask run

mime-types starting with x- are not standardized. In case of javascript it's kind of outdated. Additional the second code snippet

<?Header('Content-Type: text/javascript');?>

requires short_open_tags to be enabled. you should avoid it.

<?php Header('Content-Type: text/javascript');?>

However, the completely correct mime-type for javascript is

application/javascript

You wont be able to do this from the client side because of the Same Origin Policy set by the browsers. You wont be able to get much information from the iFrame other than basic properties like its width and height.

Also, google sets in its response header an 'X-Frame-Options' of SAMEORIGIN.

Even if you did an ajax call to google you wont be able to inspect the response because the browser enforcing Same Origin Policy.

So, the only option is to make the request from your server to see if you can display the site in your IFrame.

So, on your server.. your web app would make a request to www.google.com and then inspect the response to see if it has a header argument of X-Frame-Options. If it does exist then you know the IFrame will error.

Select select = new Select(_element);
List<WebElement> selectedOptions = select.getAllSelectedOptions();

if(selectedOptions.size() > 0){
    return true;
}else{
    return false;
}

After my previous answer disaster, I'm going to try something else.

List<Model> usrList  = 
(list.Where(n => n.application == "applicationame").ToList());
usrList.ForEach(n => n.users.RemoveAll(n => n.surname != "surname"));

Old jdbc driver is deprecated. The new one is mentioned on above configuration. Please use the same and restart the project.

If I understand your question correctly, here are four methods to do the equivalent of Excel's VLOOKUP and fill down using R:

# load sample data from Q
hous <- read.table(header = TRUE, 
                   stringsAsFactors = FALSE, 
text="HouseType HouseTypeNo
Semi            1
Single          2
Row             3
Single          2
Apartment       4
Apartment       4
Row             3")

# create a toy large table with a 'HouseType' column 
# but no 'HouseTypeNo' column (yet)
largetable <- data.frame(HouseType = as.character(sample(unique(hous$HouseType), 1000, replace = TRUE)), stringsAsFactors = FALSE)

# create a lookup table to get the numbers to fill
# the large table
lookup <- unique(hous)
  HouseType HouseTypeNo
1      Semi           1
2    Single           2
3       Row           3
5 Apartment           4

Here are four methods to fill the HouseTypeNo in the largetable using the values in the lookup table:

First with merge in base:

# 1. using base 
base1 <- (merge(lookup, largetable, by = 'HouseType'))

A second method with named vectors in base:

# 2. using base and a named vector
housenames <- as.numeric(1:length(unique(hous$HouseType)))
names(housenames) <- unique(hous$HouseType)

base2 <- data.frame(HouseType = largetable$HouseType,
                    HouseTypeNo = (housenames[largetable$HouseType]))

Third, using the plyr package:

# 3. using the plyr package
library(plyr)
plyr1 <- join(largetable, lookup, by = "HouseType")

Fourth, using the sqldf package

# 4. using the sqldf package
library(sqldf)
sqldf1 <- sqldf("SELECT largetable.HouseType, lookup.HouseTypeNo
FROM largetable
INNER JOIN lookup
ON largetable.HouseType = lookup.HouseType")

If it's possible that some house types in largetable do not exist in lookup then a left join would be used:

sqldf("select * from largetable left join lookup using (HouseType)")

Corresponding changes to the other solutions would be needed too.

Is that what you wanted to do? Let me know which method you like and I'll add commentary.

Here is my config and it works fine for PHP API:

Found a nice solution in another Stackoverflow post (using only standard libraries + dealing with jpg as well): JohnTESlade answer

And another solution (the quick way) for those who can afford running 'file' command within python, run:

import os
info = os.popen("file foo.jpg").read()
print info

Output:

foo.jpg: JPEG image data...density 28x28, segment length 16, baseline, precision 8, 352x198, frames 3

All you gotta do now is to format the output to capture the dimensions. 352x198 in my case.

Bitcode refers to to the type of code: "LLVM Bitcode" that is sent to iTunes Connect. This allows Apple to use certain calculations to re-optimize apps further (e.g: possibly downsize executable sizes). If Apple needs to alter your executable then they can do this without a new build being uploaded.

This differs from: Slicing which is the process of Apple optimizing your app for a user's device based on the device's resolution and architecture. Slicing does not require Bitcode. (Ex: only including @2x images on a 5s)

App Thinning is the combination of slicing, bitcode, and on-demand resources

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Apple Documentation on App Thinning

Or if you need it in a loop

foreach ($array as $key => $value)
{
    echo $key . ':' . $value . "\n";
}
//Result: 
//one:value
//two:value2

Yes, just open the "Source" Tab in the dev-tools and navigate to the script you want to change . Make your adjustments directly in the dev tools window and then hit ctrl+s to save the script - know the new js will be used until you refresh the whole page.

You could use str_replace to replace the <br /> tags into end of line characters.

str_replace('<br />', PHP_EOL, $textarea);

Alternatively, you could save the data in the database without calling nl2br first. That way the line breaks would remain. When you display as HTML, call nl2br. An additional benefit of this approach is that it would require less storage space in your database as a line break is 1 character as opposed to "<br />" which is 6.

This one is working perfect

QColorDialog *dialog = new QColorDialog(this);
QColor color=  dialog->getColor();
QVariant variant= color;
QString colcode = variant.toString();
ui->label->setStyleSheet("QLabel { background-color :"+colcode+" ; color : blue; }");

getColor() method returns the selected color. You can change label color using stylesheet

Your original problem was that you were checking if the list was null, which it would never be because you instantiated it with List<Integer> numbers = new ArrayList<Integer>();. However, you have updated your code to use the List.isEmpty() method to properly check if the list is empty.

The problem now is that you are never actually sending an empty list to giveList(). In your do-while loop, you add any input number to the list, even if it is -1. To prevent -1 being added, change the do-while loop to only add numbers if they are not -1. Then, the list will be empty if the user's first input number is -1.

do {
    number = Integer.parseInt(JOptionPane.showInputDialog("Enter a number (-1 to stop)"));
    /* Change this line */
    if (number != -1) numbers.add(number);
} while (number != -1);

Setting session timeout through the deployment descriptor should work - it sets the default session timeout for the web app. Calling session.setMaxInactiveInterval() sets the timeout for the particular session it is called on, and overrides the default. Be aware of the unit difference, too - the deployment descriptor version uses minutes, and session.setMaxInactiveInterval() uses seconds.

So

<session-config>
    <session-timeout>60</session-timeout>
</session-config>

sets the default session timeout to 60 minutes.

And

session.setMaxInactiveInterval(600);

sets the session timeout to 600 seconds - 10 minutes - for the specific session it's called on.

This should work in Tomcat or Glassfish or any other Java web server - it's part of the spec.

You are tying one had behind your back saying that you won't use the LESS files. I built my first Twitter Bootstrap theme using 2.0, and I did everything in CSS -- creating an override.css file. It took days to get things to work correctly.

Now we have 3.0. Let me assure you that it takes less time to learn LESS, which is pretty straight forward if you're comfortable with CSS, than doing all of those crazy CSS overrides. Making changes like the one you want is a piece of cake.

In Bootstrap 3.0, the container class controls the width, and all of the contained styles adjust to fill the container. The container width variables are at the bottom of the variables.less file.

// Container sizes
// --------------------------------------------------

// Small screen / tablet
@container-tablet:            ((720px + @grid-gutter-width));

// Medium screen / desktop
@container-desktop:           ((940px + @grid-gutter-width));

// Large screen / wide desktop
@container-lg-desktop:        ((1020px + @grid-gutter-width));

Some sites either don't have enough content to fill the 1020 display or you want a narrower frame for aesthetic reasons. Because BS uses a 12-column grid I use a multiple like 960.

"PHP message: PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini.

This php configuration parameter max_input_vars will affect not only your GET / POST / COOKIES parameters it also controls your any Form Input.

To set or change its value follow the below steps.

1) check the existing setting / value by viewing it in your php.ini file Locate php.ini file by using

<?php echo getinfo(); ?>

find below key: Loaded Configuration File : /etc/php/5.6/fpm/php.ini

2) Open the php.ini file in editable mode and do search for max_input_vars This line may be commented in your existing default setting with default value of 1000 , So remove ; to uncomment it and Edit it with your suitable value e.g. 2500.

3) Save the file and Restart the Services of PHP by using below sudo service php5.6-fpm restart

Similarly you can update any other similar PHP Configuration to your ease.

Lodash version 3.10.1

Methods compared

• _.merge(object, [sources], [customizer], [thisArg])
• _.assign(object, [sources], [customizer], [thisArg])
• _.extend(object, [sources], [customizer], [thisArg])
• _.defaults(object, [sources])
• _.defaultsDeep(object, [sources])

Similarities

• None of them work on arrays as you might expect
• _.extend is an alias for _.assign, so they are identical
• All of them seem to modify the target object (first argument)
• All of them handle null the same

Differences

• _.defaults and _.defaultsDeep processes the arguments in reverse order compared to the others (though the first argument is still the target object)
• _.merge and _.defaultsDeep will merge child objects and the others will overwrite at the root level
• Only _.assign and _.extend will overwrite a value with undefined

Tests

They all handle members at the root in similar ways.

_.assign      ({}, { a: 'a' }, { a: 'bb' }) // => { a: "bb" }
_.merge       ({}, { a: 'a' }, { a: 'bb' }) // => { a: "bb" }
_.defaults    ({}, { a: 'a' }, { a: 'bb' }) // => { a: "a"  }
_.defaultsDeep({}, { a: 'a' }, { a: 'bb' }) // => { a: "a"  }

_.assign handles undefined but the others will skip it

_.assign      ({}, { a: 'a'  }, { a: undefined }) // => { a: undefined }
_.merge       ({}, { a: 'a'  }, { a: undefined }) // => { a: "a" }
_.defaults    ({}, { a: undefined }, { a: 'bb' }) // => { a: "bb" }
_.defaultsDeep({}, { a: undefined }, { a: 'bb' }) // => { a: "bb" }

They all handle null the same

_.assign      ({}, { a: 'a'  }, { a: null }) // => { a: null }
_.merge       ({}, { a: 'a'  }, { a: null }) // => { a: null }
_.defaults    ({}, { a: null }, { a: 'bb' }) // => { a: null }
_.defaultsDeep({}, { a: null }, { a: 'bb' }) // => { a: null }

But only _.merge and _.defaultsDeep will merge child objects

_.assign      ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "b": "bb" }}
_.merge       ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a", "b": "bb" }}
_.defaults    ({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a" }}
_.defaultsDeep({}, {a:{a:'a'}}, {a:{b:'bb'}}) // => { "a": { "a": "a", "b": "bb" }}

And none of them will merge arrays it seems

_.assign      ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "bb" ] }
_.merge       ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "bb" ] }
_.defaults    ({}, {a:['a']}, {a:['bb']}) // => { "a": [ "a"  ] }
_.defaultsDeep({}, {a:['a']}, {a:['bb']}) // => { "a": [ "a"  ] }

All modify the target object

a={a:'a'}; _.assign      (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.merge       (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.defaults    (a, {b:'bb'}); // a => { a: "a", b: "bb" }
a={a:'a'}; _.defaultsDeep(a, {b:'bb'}); // a => { a: "a", b: "bb" }

None really work as expected on arrays

Note: As @Mistic pointed out, Lodash treats arrays as objects where the keys are the index into the array.

_.assign      ([], ['a'], ['bb']) // => [ "bb" ]
_.merge       ([], ['a'], ['bb']) // => [ "bb" ]
_.defaults    ([], ['a'], ['bb']) // => [ "a"  ]
_.defaultsDeep([], ['a'], ['bb']) // => [ "a"  ]

_.assign      ([], ['a','b'], ['bb']) // => [ "bb", "b" ]
_.merge       ([], ['a','b'], ['bb']) // => [ "bb", "b" ]
_.defaults    ([], ['a','b'], ['bb']) // => [ "a", "b"  ]
_.defaultsDeep([], ['a','b'], ['bb']) // => [ "a", "b"  ]

if anyone want to add a value inside loop then you can use this its working 100%

{% set ftotal= {'total': 0} %} 
{%- for pe in payment_entry -%}
    {% if ftotal.update({'total': ftotal.total + 5}) %}{% endif %} 
{%- endfor -%}

{{ftotal.total}}

output = 5

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

This didn't work

=IIf((CountRows("ScannerStatisticsData") = 0),False,True)

but this did and I can't really explain why

=IIf((CountRows("ScannerStatisticsData") < 1),False,True)

guess SSRS doesn't like equal comparisons as much as less than.

I had a similar problem. I wanted to find a string in one column and put that value in another column in the same table. The select statement below finds the text inside the parens.

When I created the query in Access I selected all fields. On the SQL view for that query, I replaced the mytable.myfield for the field I wanted to have the value from inside the parens with

SELECT Left(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")), 
            Len(Right(OtherField,Len(OtherField)-InStr((OtherField),"(")))-1) 

I ran a make table query. The make table query has all the fields with the above substitution and ends with INTO NameofNewTable FROM mytable

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

Even I got the same error, but I solved it, I had used many list in my work so I just restarted my kernel (meaning if you are using a notebook such as Jupyter or Google Colab you can just restart and again run all the cells, by doing this your problem will be solved and the error vanishes.

Thank you.

Find config.inc file under C:\wamp\apps\phpmyadmin3.5.1 Inside this file find this one line

$cfg['Servers'][$i]['password'] =";

and replace it with

$cfg['Servers'][$i]['password'] = 'Type your root password here';

If you are using the Firefox add-on sqlite-manager you can do the following:

Instead of dropping and creating the table again one can just modify it like this.

In the Columns text box, right click on the last column name listed to bring up the context menu and select Edit Column. Note that if the last column in the TABLE definition is the PRIMARY KEY then it will be necessary to first add a new column and then edit the column type of the new column in order to add the FOREIGN KEY definition. Within the Column Type box , append a comma and the

FOREIGN KEY (parent_id) REFERENCES parent(id)

definition after data type. Click on the Change button and then click the Yes button on the Dangerous Operation dialog box.

No library, using URL() WebAPI (https://developer.mozilla.org/en-US/docs/Web/API/URL)

function setURLParameter(url, parameter, value) {
    let url = new URL(url);

        return url;
    }
    url.searchParams.set(parameter, value);
    return url.href;

If you use Packer, just go far the 'shrink variables' option and gzip the resulting code. The base62 option is only for if your server cannot send gzipped files. Packer with 'shrink vars' achieves better compression the YUI, but can introduce bugs if you've skipped a semicolon somewhere.

base62 is basically a poor man's gzip, which is why gzipping base62-ed code gives you bigger files than gzipping shrink-var-ed code.

Use map function

var values = $("input[name^='card']").map(function (idx, ele) {
   return $(ele).val();
}).get();

On my machine I tried check it. My result:

Calendar.getInstance().getTime() (*1000000 times) = 402ms
new Date().getTime(); (*1000000 times) = 18ms
System.currentTimeMillis() (*1000000 times) = 16ms

Don't forget about GC (if you use Calendar.getInstance() or new Date())

In my case, I want the name of the renamed file to be unique, so I add a date-time stamp to the name. This way, the filename of the 'old' log is always unique:

if (File.Exists(clogfile))
{
    Int64 fileSizeInBytes = new FileInfo(clogfile).Length;
    if (fileSizeInBytes > 5000000)
    {
        string path = Path.GetFullPath(clogfile);
        string filename = Path.GetFileNameWithoutExtension(clogfile);
        System.IO.File.Move(clogfile, Path.Combine(path, string.Format("{0}{1}.log", filename, DateTime.Now.ToString("yyyyMMdd_HHmmss"))));
    }
}

The checkbox is in a td, so need to get the parent first:

$("input:checkbox").on("change", function() {
    $(this).parent().next().find("label").text("TESTTTT");
});

Alternatively, find a label which has a for with the same id (perhaps more performant than reverse traversal) :

$("input:checkbox").on("change", function() {
    $("label[for='" + $(this).attr('id') + "']").text("TESTTTT");
});

Or, to be more succinct just this.id:

$("input:checkbox").on("change", function() {
    $("label[for='" + this.id + "']").text("TESTTTT");
});

How to add anaconda installation directory to your PATH variables

1. open environmental variables window

Do this by either going to my computer and then right clicking the background for the context menu > "properties". On the left side open "advanced system settings" or just search for "env..." in start menu ([Win]+[s] keys).

Then click on environment variables

If you struggle with this step read this explanation.

2. Edit Path in the user environmental variables section and add three new entries:

• D:\path\to\anaconda3
• D:\path\to\anaconda3\Scripts
• D:\path\to\anaconda3\Library\bin

D:\path\to\anaconda3 should be the folder where you have installed anaconda

Click [OK] on all opened windows.

If you did everything correctly, you can test a conda command by opening a new powershell window.

conda --version

This should output something like: conda 4.8.2

Providing some other solution; we're also using react-native-image-picker; and the server side is using koa-multer; this set-up is working good:

ui

ImagePicker.showImagePicker(options, (response) => {
      if (response.didCancel) {}
      else if (response.error) {}
      else if (response.customButton) {}
      else {
        this.props.addPhoto({ // leads to handleAddPhoto()
          fileName: response.fileName,
          path: response.path,
          type: response.type,
          uri: response.uri,
          width: response.width,
          height: response.height,
        });
      }
    });

handleAddPhoto = (photo) => { // photo is the above object
    uploadImage({ // these 3 properties are required
      uri: photo.uri,
      type: photo.type,
      name: photo.fileName,
    }).then((data) => {
      // ...
    });
  }

client

export function uploadImage(file) { // so uri, type, name are required properties
  const formData = new FormData();
  formData.append('image', file);

  return fetch(`${imagePathPrefix}/upload`, { // give something like https://xx.yy.zz/upload/whatever
    method: 'POST',
    body: formData,
  }
  ).then(
    response => response.json()
  ).then(data => ({
    uri: data.uri,
    filename: data.filename,
  })
  ).catch(
    error => console.log('uploadImage error:', error)
  );
}

server

import multer from 'koa-multer';
import RouterBase from '../core/router-base';

const upload = multer({ dest: 'runtime/upload/' });

export default class FileUploadRouter extends RouterBase {
  setupRoutes({ router }) {
    router.post('/upload', upload.single('image'), async (ctx, next) => {
      const file = ctx.req.file;
      if (file != null) {
        ctx.body = {
          uri: file.filename,
          filename: file.originalname,
        };
      } else {
        ctx.body = {
          uri: '',
          filename: '',
        };
      }
    });
  }
}

In your xampppath\apache\conf\extra open file httpd-xampp.conf and find the below tag:

# Close XAMPP sites here
<LocationMatch "^/(?i:(?:xampp|licenses|phpmyadmin|webalizer|server-status|server-info))">
    Order deny,allow
    Deny from all
    Allow from ::1 127.0.0.0/8 
    ErrorDocument 403 /error/HTTP_XAMPP_FORBIDDEN.html.var
</LocationMatch>

and add

"Allow from all"

after Allow from ::1 127.0.0.0/8 {line}

Restart xampp, and you are done.

In later versions of Xampp

...you can simply remove this part

#
# New XAMPP security concept
#
<LocationMatch "^/(?i:(?:xampp|security|licenses|phpmyadmin|webalizer|server-status|server-info))">
        Require local
    ErrorDocument 403 /error/XAMPP_FORBIDDEN.html.var
</LocationMatch>

from the same file and it should work over the local network.

git isn't a centralized scm like svn so you have two options:

• Use the web interface of target platforms (f.e. GitHub REST API or GitLab REST API)
• Download the repository and display logs locally

It may be annoying to implement for many different platforms (GitHub, GitLab, BitBucket, SourceForge, Launchpad, Gogs, ...) but fetching data is pretty slow (we talk about seconds) - no solution is perfect.

An example with fetching into a temporary directory:

git clone https://github.com/rust-lang/rust.git -b master --depth 3 --bare --filter=blob:none -q .
git log -n 3 --no-decorate --format=oneline

Alternatively:

git init --bare -q
git remote add -t master origin https://github.com/rust-lang/rust.git
git fetch --depth 3 --filter=blob:none -q
git log -n 3 --no-decorate --format=oneline origin/master

Both are optimized for performance by restricting to exactly 3 commits of one branch into a minimal local copy without file contents and preventing console outputs. Though opening a connection and calculating deltas during fetch takes some time.

An example with GitHub:

GET https://api.github.com/repos/rust-lang/rust/commits?sha=master&per_page=3

An example with GitLab:

GET https://gitlab.com/api/v4/projects/inkscape%2Finkscape/repository/commits?ref_name=master&per_page=3

Both are really fast but have different interfaces (like every platform).

Disclaimer: Rust and Inkscape were chosen because of their size and safety to stay, no advertisement

The best way to access files from resource folder inside a jar is it to use the InputStream via getResourceAsStream. If you still need a the resource as a file instance you can copy the resource as a stream into a temporary file (the temp file will be deleted when the JVM exits):

public static File getResourceAsFile(String resourcePath) {
    try {
        InputStream in = ClassLoader.getSystemClassLoader().getResourceAsStream(resourcePath);
        if (in == null) {
            return null;
        }

        File tempFile = File.createTempFile(String.valueOf(in.hashCode()), ".tmp");
        tempFile.deleteOnExit();

        try (FileOutputStream out = new FileOutputStream(tempFile)) {
            //copy stream
            byte[] buffer = new byte[1024];
            int bytesRead;
            while ((bytesRead = in.read(buffer)) != -1) {
                out.write(buffer, 0, bytesRead);
            }
        }
        return tempFile;
    } catch (IOException e) {
        e.printStackTrace();
        return null;
    }
}

If you have deadlocks occurring in a combination of locks, threads and forks in the logging module, that is reported in bug report 6721 (see also related SO question).

There is a small fixup solution posted here.

However, that will just fix any potential deadlocks in logging. That will not fix that things are maybe garbled up. See the other answers presented here.

if (combo1.SelectedIndex > -1)
{
    // do something
}

if any item is selected selected index will be greater than -1

XOR is short for exclusive or. It is a logical, binary operator that requires that one of the two operands be true but not both.

So these statements are true:

TRUE XOR FALSE
FALSE XOR TRUE

And these statements are false:

FALSE XOR FALSE
TRUE XOR TRUE

There really isn't such a thing as an"exclusive and" (or XAND) since in theory it would have the same exact requirements as XOR. There also isn't an XNOT since NOT is a unary operator that negates its single operand (basically it just flips a boolean value to its opposite) and as such it cannot support any notion of exclusivity.

I'm not 100% sure what your NonIntersect method is supposed to do (regarding set theory) - is it
B \ A (everything from B that does not occur in A)?
If yes, then you should be able to use the Except operation (B.Except(A)).

try

String[][] arrays = new String[5][];

In case you couldn't find "Import code" button on github, you can:

1. directly open Github Importer and enter the url. It will look like:
2. give it a name (or it will import the name automatically)
3. select Public or Private repo
4. Click Begin Import

the worked proposition for me is __call__ on class who create list of little numbers:

ArrayList and Vector both implements List interface and maintains insertion order.But there are many differences between ArrayList and Vector classes...

ArrayList -

1. ArrayList is not synchronized.
2. ArrayList increments 50% of current array size if number of element exceeds from its capacity.
3. ArrayList is not a legacy class, it is introduced in JDK 1.2.
4. ArrayList is fast because it is non-synchronized.
5. ArrayList uses Iterator interface to traverse the elements.

Vector -

6. Vector is synchronized.
7. Vector increments 100% means doubles the array size if total number of element exceeds than its capacity.

8. Vector is a legacy class.

9. Vector is slow because it is synchronized i.e. in multithreading environment, it will hold the other threads in runnable or non-runnable state until current thread releases the lock of object.

10. Vector uses Enumeration interface to traverse the elements. But it can use Iterator also.

.each() should work for you. http://api.jquery.com/jQuery.each/ or http://api.jquery.com/each/ or you could use .map.

var newArray = $(array).map(function(i) {
    return $('#event' + i, response).html();
});

Edit: I removed the adding of the prepended 0 since it is suggested to not use that.

If you must have it use

var newArray = $(array).map(function(i) {
    var number = '' + i;
    if (number.length == 1) {
        number = '0' + number;
    }   
    return $('#event' + number, response).html();
});

It’s just HTML with Server Side Includes.

My guess is it's not in your path.
in bash, try:
echo $PATH
and
sudo which nginx
And see if the folder containing nginx is also in your $PATH variable.
If not, either add the folder to your path environment variable, or create an alias (and put it in your .bashrc) ooor your could create a link i guess.
or sudo nginx -v if you just want that...

I find htop a useful tool.

sudo apt-get install htop

and then

free -m

will give the information you need.

string connectionString= ServerName + DatabaseName + SecurityType;
using (SqlConnection connection = new SqlConnection(connectionString))
using (SqlBulkCopy bulkCopy = new SqlBulkCopy(connection)) {
    connection.Open();
    bulkCopy.DestinationTableName = "TableName";
    try {
        bulkCopy.WriteToServer(dataTableName);
    } catch (Exception e) {
        Console.Write(e.Message);
    }
}

Please note that the structure of the database table and the table name should be the same or it will throw an exception.

Those who use WPF

for (int i = 0; i < dataGridName.Items.Count; i++)
{
      string cellValue= ((DataRowView)dataGridName.Items[i]).Row["columnName"].ToString();                
      if (cellValue.Equals("Search_string")) // check the search_string is present in the row of ColumnName
      {
         object item = dataGridName.Items[i];
         dataGridName.SelectedItem = item; // selecting the row of dataGridName
         dataGridName.ScrollIntoView(item);                    
         break;
      }
}

if you want to get the selected row items after this, the follwing code snippet is helpful

DataRowView drv = dataGridName.SelectedItem as DataRowView;
DataRow dr = drv.Row;
string item1= Convert.ToString(dr.ItemArray[0]);// get the first column value from selected row 
string item2= Convert.ToString(dr.ItemArray[1]);// get the second column value from selected row 

After five years, I can see this is still a very relevant subject. Somewhat mirroring leucos's answer which I find the best in my case, using ansible tools only (without any centralised authentication, tokens or whatever). This assumes you have the same username and the same public key on all servers. If you don't, of course you'd need to be more specific and add the corresponding variables next to the hosts:

[all:vars]
ansible_ssh_user=ansible
ansible_ssh_private_key_file=home/user/.ssh/mykey
[group]
192.168.0.50 ansible_sudo_pass='{{ myserver_sudo }}'

ansible-vault create mypasswd.yml
ansible-vault edit mypasswd.yml

Add:

myserver_sudo: mysecretpassword

Then:

ansible-playbook -i inv.ini my_role.yml --ask-vault --extra-vars '@passwd.yml'

At least this way you don't have to write more the variables which point to the passwords.

Kill the braces.

var defaults = {
 backgroundcolor: '#000',
 color: '#fff',
 weekdays: ['sun','mon','tue','wed','thu','fri','sat']
};

This is very confusing, and if you are using IDE like pycharm, it's little more confusing. What worked for me: 1. Make pycharm project settings (if you are running python from a VE or from python directory) 2. There is no wrong the way you defined. sometime it works with from folder1.file1 import class

if it does not work, use import folder1.file1 3. Your environment variable should be correctly mentioned in system or provide it in your command line argument.

Under Windows7 Pro, I found that Arun's solution worked for me: I could get this to work even with "no user logged on", I did choose use highest priveledges.

From past experience, you must have an account with a password (blank passwords are no good), and if the program doesn't prompt you for the password when you finish the wizard, go back in and edit something till it does!

This is the method in case its not clear which worked

Action: start a program
Program/script : cmd
      (doesn't need the .exe bit!)
Add arguments:
    /c start "" "E:\Django-1.4.1\setup.bat" 

List comprehension will lead you to a solution.

But the right way to copy a object in python is using python module copy - Shallow and deep copy operations.

l=[1,2,3,0,0,1]
for i in range(0,len(l)):
   if l[i]==0:
       l.pop(i)

If instead of this,

import copy
l=[1,2,3,0,0,1]
duplicate_l = copy.copy(l)
for i in range(0,len(l)):
   if l[i]==0:
       m.remove(i)
l = m

Then, your own code would have worked. But for optimization, list comprehension is a good solution.

System read-only variable %CD% keeps the path of the caller of the batch, not the batch file location.

You can get the name of the batch script itself as typed by the user with %0 (e.g. scripts\mybatch.bat). Parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script (e.g. W:\scripts\) and %~f0 will return the full pathname (e.g. W:\scripts\mybatch.cmd).

You can refer to other files in the same folder as the batch script by using this syntax:

CALL %0\..\SecondBatch.cmd

This can even be used in a subroutine, Echo %0 will give the call label but, echo "%~nx0" will give you the filename of the batch script.

When the %0 variable is expanded, the result is enclosed in quotation marks.

More on batch parameters.

I resolved by adding - %AppData%\npm\node_modules@angular\cli\bin\ path to my environment variables path

If the charset of the tables is the same as it's content try to use mysql_set_charset('UTF8', $link_identifier). Note that MySQL uses UTF8 to specify the UTF-8 encoding instead of UTF-8 which is more common.

Check my other answer on a similar question too.

But what if the container is not the viewport (body)?

The real answer is in the transform property allows you to visually manipulate an element by skewing, rotating, translating, or scaling:

https://css-tricks.com/almanac/properties/t/transform/

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

(This is already answered in comments, but since it lacks an actual answer, I'm writing this.)

This problem arises in newer versions of Visual C++ (the older versions usually just silently linked the program and it would crash and burn at run time.) It means that some of the libraries you are linking with your program (or even some of the source files inside your program itself) are using different versions of the CRT (the C RunTime library.)

To correct this error, you need to go into your Project Properties (and/or those of the libraries you are using,) then into C/C++, then Code Generation, and check the value of Runtime Library; this should be exactly the same for all the files and libraries you are linking together. (The rules are a little more relaxed for linking with DLLs, but I'm not going to go into the "why" and into more details here.)

There are currently four options for this setting:

1. Multithreaded Debug
2. Multithreaded Debug DLL
3. Multithreaded Release
4. Multithreaded Release DLL

Your particular problem seems to stem from you linking a library built with "Multithreaded Debug" (i.e. static multithreaded debug CRT) against a program that is being built using the "Multithreaded Debug DLL" setting (i.e. dynamic multithreaded debug CRT.) You should change this setting either in the library, or in your program. For now, I suggest changing this in your program.

Note that since Visual Studio projects use different sets of project settings for debug and release builds (and 32/64-bit builds) you should make sure the settings match in all of these project configurations.

For (some) more information, you can see these (linked from a comment above):

1. Linker Tools Warning LNK4098 on MSDN
2. /MD, /ML, /MT, /LD (Use Run-Time Library) on MSDN
3. Build errors with VC11 Beta - mixing MTd libs with MDd exes fail to link on Bugzilla@Mozilla

UPDATE: (This is in response to a comment that asks for the reason that this much care must be taken.)

If two pieces of code that we are linking together are themselves linking against and using the standard library, then the standard library must be the same for both of them, unless great care is taken about how our two code pieces interact and pass around data. Generally, I would say that for almost all situations just use the exact same version of the standard library runtime (regarding debug/release, threads, and obviously the version of Visual C++, among other things like iterator debugging, etc.)

The most important part of the problem is this: having the same idea about the size of objects on either side of a function call.

Consider for example that the above two pieces of code are called A and B. A is compiled against one version of the standard library, and B against another. In A's view, some random object that a standard function returns to it (e.g. a block of memory or an iterator or a FILE object or whatever) has some specific size and layout (remember that structure layout is determined and fixed at compile time in C/C++.) For any of several reasons, B's idea of the size/layout of the same objects is different (it can be because of additional debug information, natural evolution of data structures over time, etc.)

Now, if A calls the standard library and gets an object back, then passes that object to B, and B touches that object in any way, chances are that B will mess that object up (e.g. write the wrong field, or past the end of it, etc.)

The above isn't the only kind of problems that can happen. Internal global or static objects in the standard library can cause problems too. And there are more obscure classes of problems as well.

All this gets weirder in some aspects when using DLLs (dynamic runtime library) instead of libs (static runtime library.)

This situation can apply to any library used by two pieces of code that work together, but the standard library gets used by most (if not almost all) programs, and that increases the chances of clash.

What I've described is obviously a watered down and simplified version of the actual mess that awaits you if you mix library versions. I hope that it gives you an idea of why you shouldn't do it!

Do you mean this?

var listOfList = new List<List<int>>() {
    new List<int>() { 1, 2 },
    new List<int>() { 3, 4 },
    new List<int>() { 5, 6 }
};
var list = new List<int> { 9, 9, 9 };
var result = list.Concat(listOfList.SelectMany(x => x));

foreach (var x in result) Console.WriteLine(x);

Results in: 9 9 9 1 2 3 4 5 6

In addition to the answer of eldos I also needed gcc in CentOS 7:

yum install libcurl-devel gcc

1. Add your JDK's /bin folder to the PATH environmental variable. You can do this under System settings > Environmental variables, or via CLI:

   set PATH=%PATH%;C:\Program Files\Java\jdk1.7.0_80\bin
   

2. Close and reopen your CLI window

You can determine window scroll bar with document as below using jquery + javascript:

var scrollbarWidth = ($(document).width() - window.innerWidth);
console.info("Window Scroll Bar Width=" + scrollbarWidth );

I am using below code for today and database date.

TIMESTAMPDIFF(MINUTE,T.runTime,NOW()) > 20

According to the documentation, the first argument can be any of the following:

In C# 7 it's possible to use a when clause in a case statement.

int age = 12;
switch (age) 
{
  case int i when i >=1 && i <= 8:
    System.Console.WriteLine("You are only " + age + " years old. You must be kidding right. Please fill in your *real* age.");
    break;
  case int i when i >=9 && i <= 15:
    System.Console.WriteLine("You are only " + age + " years old. That's too young!");
    break;
  case int i when i >=16 && i <= 100:
    System.Console.WriteLine("You are " + age + " years old. Perfect.");
    break;
  default:
    System.Console.WriteLine("You an old person.");
    break;
}

There are many possibilities to solve this task.

1. RUN the batch file with full path

The easiest solution is running the batch file with full path.

"F:\- Big Packets -\kitterengine\Common\Template.bat"

Once end of batch file Template.bat is reached, there is no return to previous script in case of the command line above is within a *.bat or *.cmd file.

The current directory for the batch file Template.bat is the current directory of the current process. In case of Template.bat requires that the directory of this batch file is the current directory, the batch file Template.bat should contain after @echo off as second line the following command line:

cd /D "%~dp0"

Run in a command prompt window cd /? for getting displayed the help of this command explaining parameter /D ... change to specified directory also on a different drive.

Run in a command prompt window call /? for getting displayed the help of this command used also in 2., 4. and 5. solution and explaining also %~dp0 ... drive and path of argument 0 which is the name of the batch file.

2. CALL the batch file with full path

Another solution is calling the batch file with full path.

call "F:\- Big Packets -\kitterengine\Common\Template.bat"

The difference to first solution is that after end of batch file Template.bat is reached the batch processing continues in batch script containing this command line.

For the current directory read above.

3. Change directory and RUN batch file with one command line

There are 3 operators for running multiple commands on one command line: &, && and ||.
For details see answer on Single line with multiple commands using Windows batch file

I suggest for this task the && operator.

cd /D "F:\- Big Packets -\kitterengine\Common" && Template.bat

As on first solution there is no return to current script if this is a *.bat or *.cmd file and changing the directory and continuation of batch processing on Template.bat is successful.

4. Change directory and CALL batch file with one command line

This command line changes the directory and on success calls the batch file.

cd /D "F:\- Big Packets -\kitterengine\Common" && call Template.bat

The difference to third solution is the return to current batch script on exiting processing of Template.bat.

5. Change directory and CALL batch file with keeping current environment with one command line

The four solutions above change the current directory and it is unknown what Template.bat does regarding

1. current directory
2. environment variables
3. command extensions state
4. delayed expansion state

In case of it is important to keep the environment of current *.bat or *.cmd script unmodified by whatever Template.bat changes on environment for itself, it is advisable to use setlocal and endlocal.

Run in a command prompt window setlocal /? and endlocal /? for getting displayed the help of these two commands. And read answer on change directory command cd ..not working in batch file after npm install explaining more detailed what these two commands do.

setlocal & cd /D "F:\- Big Packets -\kitterengine\Common" & call Template.bat & endlocal

Now there is only & instead of && used as it is important here that after setlocal is executed the command endlocal is finally also executed.

ONE MORE NOTE

If batch file Template.bat contains the command exit without parameter /B and this command is really executed, the command process is always exited independent on calling hierarchy. So make sure Template.bat contains exit /B or goto :EOF instead of just exit if there is exit used at all in this batch file.

As the others have said already, your first line should be

#!/usr/bin/env ruby

And you also have to make it executable: (in the shell)

chmod +x test.rb

Then follows the ruby code. If you open a file

File.open("file", "r") do |io|
    # do something with io
end

the file is opened in the current directory you'd get with pwd in the shell.

The path to your script is also simple to get. With $0 you get the first argument of the shell, which is the relative path to your script. The absolute path can be determined like that:

#!/usr/bin/env ruby
require 'pathname'
p Pathname.new($0).realpath()

For file system operations I almost always use Pathname. This is a wrapper for many of the other file system related classes. Also useful: Dir, File...

Use the text method [text()] to get text in the div element, by identifing the element by class or id.

You can run the ant task echoproperties and look for "java.version" or ant -v and look for "Java version", e.g. on my machine

ant echoproperties | grep java.version

shows

[echoproperties] java.version=11.0.9.1

and

ant -v | grep -i "java version"

shows

Detected Java version: 11 in: /opt/java/zulu11.43.55-ca-jdk11.0.9.1-linux_x64

If you don't care about supporting old browsers, you can use :not() to exclude that element:

.parent:hover span:not(:hover) {
    border: 10px solid red;
}

Demo: http://jsfiddle.net/vz9A9/1/

If you do want to support them, the I guess you'll have to either use JavaScript or override the CSS properties again:

.parent span:hover {
    border: 10px solid green;
}

We have solved the same error by following the below steps.

linux command for this type of error occurred then, first of all, check your php.ini file

If your php.ini file exists then in configuration file simply uncomment the extension:

I couldn't find an off-the-shelf module that added this function, so I wrote one:

In Access, go to the Database Tools ribbon, in the Macro area click into Visual Basic. In the top left Project area, right click the name of your file and select Insert -> Module. In the module paste this:

Public Function Substring_Index(strWord As String, strDelim As String, intCount As Integer) As String

Substring_Index = delims

start = 0
test = ""

For i = 1 To intCount
    oldstart = start + 1
    start = InStr(oldstart, strWord, strDelim)
    Substring_Index = Mid(strWord, oldstart, start - oldstart)
Next i

End Function

Save the module as module1 (the default). You can now use statements like:

SELECT Substring_Index([fieldname],",",2) FROM table

There is actually a native solution to this, using the four-values to background-position

.CssClass {background-position: right 10px top 20px;}

This means 10px from right and 20px from top. you can also use three values the fourth value will be count as 0.

I've written a little tool called psql2csv that encapsulates the COPY query TO STDOUT pattern, resulting in proper CSV. It's interface is similar to psql.

psql2csv [OPTIONS] < QUERY
psql2csv [OPTIONS] QUERY

The query is assumed to be the contents of STDIN, if present, or the last argument. All other arguments are forwarded to psql except for these:

-h, --help           show help, then exit
--encoding=ENCODING  use a different encoding than UTF8 (Excel likes LATIN1)
--no-header          do not output a header

File 1

class ClassA {

    public $name = 'A';

    public function getName(){
        return $this->name;
    }

}

File 2

include("file1.php");
class ClassB {

    public $name = 'B';

    public function getName(){
        return $this->name;
    }

    public function callA(){
        $a = new ClassA();
        return $a->getName();
    }

    public static function callAStatic(){
        $a = new ClassA();
        return $a->getName();
    }

}

$b = new ClassB();
echo $b->callA();
echo $b->getName();
echo ClassB::callAStatic();

To read characters try

scan("/PathTo/file.csv", "")

If you're reading numeric values, then just use

scan("/PathTo/file.csv")

scan by default will use white space as separator. The type of the second arg defines 'what' to read (defaults to double()).

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE would have been too narrow in its meaning.

DATEADD only returned Function does not exist on MySQL 5.5.53 (I know it's old)

Instead, I found DatePlayed > DATE_SUB(CURRENT_TIMESTAMP, INTERVAL 30 minute) to produce the desired result

By default, html buttons submit a form.

This is due to the fact that even buttons located outside of a form act as submitters (see the W3Schools website: http://www.w3schools.com/tags/att_button_form.asp)

In other words, the button type is "submit" by default

<button type="submit">Button Text</button>

Therefore an easy way to get around this is to use the button type.

<button type="button">Button Text</button>

Other options include returning false at the end of the onclick or any other handler for when the button is clicked, or to using an < input> tag instead

To find out more, check out the Mozilla Developer Network's information on buttons: https://developer.mozilla.org/en/docs/Web/HTML/Element/button

Nobody mentioned the ability to use them in switch statements; I'll throw that in as well.

This allows arbitrarily complex enums to be used in a clean way without using instanceof, potentially confusing if sequences, or non-string/int switching values. The canonical example is a state machine.

Thanks guys for help, here is the code I tried which is working for me

   UILabel *instructions = [[UILabel alloc]initWithFrame:CGRectMake(10, 225, 300, 180)];
   NSString *text = @"First take clear picture and then try to zoom in to fit the ";
   instructions.text = text;
   instructions.textAlignment = UITextAlignmentCenter;
   instructions.lineBreakMode = NSLineBreakByWordWrapping;
   [instructions setTextColor:[UIColor grayColor]];

   CGSize expectedLabelSize = [text sizeWithFont:instructions.font 
                                constrainedToSize:instructions.frame.size
                                    lineBreakMode:UILineBreakModeWordWrap];

    CGRect newFrame = instructions.frame;
    newFrame.size.height = expectedLabelSize.height;
    instructions.frame = newFrame;
    instructions.numberOfLines = 0;
    [instructions sizeToFit];
    [self addSubview:instructions];

lockless Copy and Write approach works great if you're not dealing with too many items. Here's a class I wrote:

public class CopyAndWriteList<T>
{
    public static List<T> Clear(List<T> list)
    {
        var a = new List<T>(list);
        a.Clear();
        return a;
    }

    public static List<T> Add(List<T> list, T item)
    {
        var a = new List<T>(list);
        a.Add(item);
        return a;
    }

    public static List<T> RemoveAt(List<T> list, int index)
    {
        var a = new List<T>(list);
        a.RemoveAt(index);
        return a;
    }

    public static List<T> Remove(List<T> list, T item)
    {
        var a = new List<T>(list);
        a.Remove(item);
        return a;
    }

}

example usage: orders_BUY = CopyAndWriteList.Clear(orders_BUY);

This is because you define your "doc" variable outside of your click event. The first time you click the button the doc variable contains a new jsPDF object. But when you click for a second time, this variable can't be used in the same way anymore. As it is already defined and used the previous time.

change it to:

$(function () {

    var specialElementHandlers = {
        '#editor': function (element,renderer) {
            return true;
        }
    };
 $('#cmd').click(function () {
        var doc = new jsPDF();
        doc.fromHTML(
            $('#target').html(), 15, 15, 
            { 'width': 170, 'elementHandlers': specialElementHandlers }, 
            function(){ doc.save('sample-file.pdf'); }
        );

    });  
});

and it will work.

Answer by Rick and MadX is the right way to do the steps (Thumbs Up for the answer)

In my case I am using Akcess USB Type C Data Sync Cable For Nexus 5x, 5P - White As Nexus 5x do not supply type C to usb cable I purchased it from some vendor.

Having the same issue. What I am doing stupidly is:- I am connecting the cable in wrong way. After I reconnect it from upside down its working for me.

I might think that some of the Cables do not support debuggable. But its in my case.

This(Image) is my case the Type C should be as USB side symbol. A stupid solution, but work for me

This is because interfaces do not allow to define the method body in it.but we should have to define the constructor in the same class as interfaces have by default abstract modifier for all the methods to define. That's why we can not define constructor in the interfaces.

<ul>
    <li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 1" required><label>Box 1</label></li>
    <li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 2" required><label>Box 2</label></li>
    <li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 3" required><label>Box 3</label></li>
    <li><input class="checkboxes" name="BoxSelect[]" type="checkbox" value="Box 4" required><label>Box 4</label></li>
</ul>

<script type="text/javascript">
$(document).ready(function(){
    var checkboxes = $('.checkboxes');
    checkboxes.change(function(){
        if($('.checkboxes:checked').length>0) {
            checkboxes.removeAttr('required');
        } else {
            checkboxes.attr('required', 'required');
        }
    });
});
</script>

Replace whatever is in the address bar with this:

javascript:document.getElementById('serverTime').innerHTML='[text here]';

Example.

I struggled to solve a similar problem around data table classes instead of messages. The root issue mentioned above of casting a non-generic version of the class to a derived generic version was the same.

In order to allow injection into a portable class library which did not support database libraries, I introduced a set of interface classes, with the intent that I could pass a type and get a matching generic. It ended up needing to implement a generic method.

// Interface for injection
public interface IDatabase
{
    // Original, non-functional signature:
    IDatatable<object> GetDataTable(Type dataType);

    // Functional method using a generic method:
    IDatatable<T> GetDataTable<T>();
}

And this the whole implementation using the generic method above.

The generic class that will be cast from a dictionary.

// Non-generic base class allows listing tables together
abstract class Datatable
{
    Datatable(Type storedClass)
    {
      StoredClass = storedClass;
    }

    Type StoredClass { get; private set; }
}

// Generic inheriting class
abstract class Datatable<T>: Datatable, IDatatable<T>
{
    protected Datatable()
        :base(typeof(T))
    {
    }
}

This is the class that stores the generic class and casts it to satisfy the generic method in the interface

class Database
{
    // Dictionary storing the classes using the non-generic base class
    private Dictionary<Type, Datatable> _tableDictionary;

    protected Database(List<Datatable> tables)
    {
        _tableDictionary = new Dictionary<Type, Datatable>();
        foreach (var table in tables)
        {
            _tableDictionary.Add(table.StoredClass, table);
        }
    }

    // Interface implementation, casts the generic
    public IDatatable<T> GetDataTable<T>()
    {
        Datatable table = null;

        _tableDictionary.TryGetValue(typeof(T), out table);

        return table as IDatatable<T>;
    }
}

And finally the calling of the interface method.

IDatatable<CustomerAccount> table = _database.GetDataTable<CustomerAccount>();

Uncaught InvalidValueError: setPosition: not a LatLng or LatLngLiteral: in property lat: not a number

Means you are not passing numbers into the google.maps.LatLng constructor. Per your comment:

/*Information from chromium debugger
trader: Object
    geo: Object
        lat: "49.014821"
        lon: "10.985072"

*/

trader.geo.lat and trader.geo.lon are strings, not numbers. Use parseFloat to convert them to numbers:

var myLatlng = new google.maps.LatLng(parseFloat(trader.geo.lat),parseFloat(trader.geo.lon));

You can modify the id without having to use getElementById

Example:

<div id = 'One' onclick = "One.id = 'Two'; return false;">One</div>

You can see it here: http://jsbin.com/elikaj/1/

Tested with Mozilla Firefox 22 and Google Chrome 60.0

my mistake was making the target name "filename.c:" instead of just "filename:"

From the fine manual.

You must own the table to use ALTER TABLE.

Or be a database superuser.

ERROR: must be owner of relation contact

PostgreSQL error messages are usually spot on. This one is spot on.

Try the following code:

SELECT *
FROM users
WHERE firstname IN ('joe','jane');

I was getting these errors when trying to load my test environment (via rake test or autotest) and the IRB suggestions didn't help. I ended up wrapping my entire test/test_helper.rb in a begin/rescue block and that fixed things up.

begin
  class ActiveSupport::TestCase
    #awesome stuff
  end
rescue => e
  puts e.backtrace
end

Use Default toolkit for this

frame.setIconImage(Toolkit.getDefaultToolkit().getImage("Icon.png"));

f.write(plaintext)
f.write("\n".encode("utf-8"))

Just git branch without options.

From the manpage:

With no arguments, existing branches are listed and the current branch will be highlighted with an asterisk.

You can use recyclerView.getChildAt() to get each visible child, and setting some tag convertview.setTag(index) on these view in adapter code will help you to relate it with adapter data.

It can also mean that the server is completely inaccessible - I was getting this when trying to hit a server that was offline

My client was configured to connect to localhost:3000, but no server was running on that port.

This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.

<LimitExcept OPTIONS>
    AuthType Basic
    AuthName <AUTH_NAME>
    Require valid-user
    AuthUserFile <FILE_PATH>
</LimitExcept>

In the specific case of sed, the -i option that others have already mentioned is far and away the simplest and sanest one.

In the more general case, sponge, from the moreutils collection, does exactly what you want: it lets you replace a file with the result of processing it, in a way specifically designed to keep the processing step from tripping over itself by overwriting the very file it's working on. To quote the sponge man page:

sponge reads standard input and writes it out to the specified file. Unlike a shell redirect, sponge soaks up all its input before writing the output file. This allows constructing pipelines that read from and write to the same file.

I hope it helps.

This is not a matter of accuracy, nor is it a matter of precision. It is a matter of meeting the expectations of humans who use base 10 for calculations instead of base 2. For example, using doubles for financial calculations does not produce answers that are "wrong" in a mathematical sense, but it can produce answers that are not what is expected in a financial sense.

Even if you round off your results at the last minute before output, you can still occasionally get a result using doubles that does not match expectations.

Using a calculator, or calculating results by hand, 1.40 * 165 = 231 exactly. However, internally using doubles, on my compiler / operating system environment, it is stored as a binary number close to 230.99999... so if you truncate the number, you get 230 instead of 231. You may reason that rounding instead of truncating would have given the desired result of 231. That is true, but rounding always involves truncation. Whatever rounding technique you use, there are still boundary conditions like this one that will round down when you expect it to round up. They are rare enough that they often will not be found through casual testing or observation. You may have to write some code to search for examples that illustrate outcomes that do not behave as expected.

Assume you want to round something to the nearest penny. So you take your final result, multiply by 100, add 0.5, truncate, then divide the result by 100 to get back to pennies. If the internal number you stored was 3.46499999.... instead of 3.465, you are going to get 3.46 instead 3.47 when you round the number to the nearest penny. But your base 10 calculations may have indicated that the answer should be 3.465 exactly, which clearly should round up to 3.47, not down to 3.46. These kinds of things happen occasionally in real life when you use doubles for financial calculations. It is rare, so it often goes unnoticed as an issue, but it happens.

If you use base 10 for your internal calculations instead of doubles, the answers are always exactly what is expected by humans, assuming no other bugs in your code.

You may also want to try two backslashes (\\") to escape the escape character.

RequireJS can be configured to append a value to each of the script urls for cache busting.

From the RequireJS documentation (http://requirejs.org/docs/api.html#config):

urlArgs: Extra query string arguments appended to URLs that RequireJS uses to fetch resources. Most useful to cache bust when the browser or server is not configured correctly.

Example, appending "v2" to all scripts:

require.config({
    urlArgs: "bust=v2"
});

For development purposes, you can force RequireJS to bypass the cache by appending a timestamp:

require.config({
    urlArgs: "bust=" + (new Date()).getTime()
});

How about creating an <a> with _blank as target attribute value and the url as href, with style display:hidden with a a children element? Then add to the DOM and then trigger the click event on a children element.

UPDATE

That doesn't work. The browser prevents the default behaviour. It could be triggered programmatically, but it doesn't follow the default behaviour.

Check and see for yourself: http://jsfiddle.net/4S4ET/

You can use String.split(String regex):

String input = "aabbab";
String[] parts = input.split("(?!^)");

I ended up writing a script (I'm trying to teach myself the finer points of bash scripting, so that's why you don't see something like Perl here). It's not exactly a simple affair, but it does most of what I need. It uses Kyle's suggestion for looking up individual users' crontabs, but also deals with /etc/crontab (including the scripts launched by run-parts in /etc/cron.hourly, /etc/cron.daily, etc.) and the jobs in the /etc/cron.d directory. It takes all of those and merges them into a display something like the following:

mi     h    d  m  w  user      command
09,39  *    *  *  *  root      [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -print0 | xargs -r -0 rm

Note that it shows the user, and more-or-less sorts by hour and minute so that I can see the daily schedule.

Going forward, the new HTML Intersection Observer API is the thing you're looking for. It allows you to configure a callback that is called whenever one element, called the target, intersects either the device viewport or a specified element. It's available in latest versions of Chrome, Firefox and Edge. See https://developer.mozilla.org/en-US/docs/Web/API/Intersection_Observer_API for more info.

Simple code example for observing display:none switching:

// Start observing visbility of element. On change, the
//   the callback is called with Boolean visibility as
//   argument:

function respondToVisibility(element, callback) {
  var options = {
    root: document.documentElement,
  };

  var observer = new IntersectionObserver((entries, observer) => {
    entries.forEach(entry => {
      callback(entry.intersectionRatio > 0);
    });
  }, options);

  observer.observe(element);
}

To complete André's answer, an ant solution could be like the one described in Emacs, JDEE, Ant, and the Eclipse Java Compiler, as in:

      <javac
          srcdir="${src}"
          destdir="${build.dir}/classes"> 
        <compilerarg 
           compiler="org.eclipse.jdt.core.JDTCompilerAdapter" 
           line="-warn:+unused -Xemacs"/>
        <classpath refid="compile.classpath" />
      </javac>

The compilerarg element also allows you to pass in additional command line args to the eclipse compiler.

You can find a full ant script example here which would be invoked in a command line with:

java -cp C:/eclipse-SDK-3.4-win32/eclipse/plugins/org.eclipse.equinox.launcher_1.0.100.v20080509-1800.jar org.eclipse.core.launcher.Main -data "C:\Documents and Settings\Administrator\workspace" -application org.eclipse.ant.core.antRunner -buildfile build.xml -verbose

BUT all that involves ant, which is not what Keith is after.

For a batch compilation, please refer to Compiling Java code, especially the section "Using the batch compiler"

The batch compiler class is located in the JDT Core plug-in. The name of the class is org.eclipse.jdt.compiler.batch.BatchCompiler. It is packaged into plugins/org.eclipse.jdt.core_3.4.0..jar. Since 3.2, it is also available as a separate download. The name of the file is ecj.jar.
Since 3.3, this jar also contains the support for jsr199 (Compiler API) and the support for jsr269 (Annotation processing). In order to use the annotations processing support, a 1.6 VM is required.

Running the batch compiler From the command line would give

java -jar org.eclipse.jdt.core_3.4.0<qualifier>.jar -classpath rt.jar A.java

or:

java -jar ecj.jar -classpath rt.jar A.java

All java compilation options are detailed in that section as well.

The difference with the Visual Studio command line compilation feature is that Eclipse does not seem to directly read its .project and .classpath in a command-line argument. You have to report all information contained in the .project and .classpath in various command-line options in order to achieve the very same compilation result.

So, then short answer is: "yes, Eclipse kind of does." ;)

Have you tried using the value in MB ?

php_value memory_limit 2048M

Also try editing this value in php.ini not Apache.

Use limitTo filter to display a limited number of results in ng-repeat.

<ul class="phones">
      <li ng-repeat="phone in phones | limitTo:5">
        {{phone.name}}
        <p>{{phone.snippet}}</p>
      </li>
</ul>

Deleting file .condarc (eg./root/.condarc) in the user's home directory before installation, resolved the issue.
