I try this same method, but with a different list with more values in the function map. My problem was to forget a return statement. This is very important :)

 bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) { return Tab(text: title)}).toList()
      ,
    ),

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

Solution that worked for me:

• Delete node_modules and dist folder
• (in cmd)>> ng update --all --force
• (in cmd)>> npm install typescript@">=3.4.0 and <3.5.0" --save-dev --save-exact
• (in cmd)>> npm install --save core-js
• Commenting import 'core-js/es7/reflect'; in polyfill.ts
• (in cmd)>> ng serve

I don't know why everyone is using 2 copies of the same list to solve this. This uses too much RAM...

Why not just hide the elements that are not found, and simply store their index in a Set to be able to restore them later? That's much less RAM especially if your objects are quite large.

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.SampleViewHolders>{

            }
        }
        notifyDataSetChanged();
    }

    public class SampleViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener
    {
        public ImageView imgImageView;
        public TextView nameTextView;

        private final CardView layout;
        private final CardView.LayoutParams hiddenLayoutParams;
        private final CardView.LayoutParams shownLayoutParams;

        
        public SampleViewHolders(View itemView)
        {
            super(itemView);
            itemView.setOnClickListener(this);
            imgImageView = (ImageView) itemView.findViewById(R.id.some_image_view);
            nameTextView = (TextView) itemView.findViewById(R.id.display_name_textview);

            layout = itemView.findViewById(R.id.card_view); //card_view is the id of my androidx.cardview.widget.CardView in my xml layout
            //prepare hidden layout params with height = 0, and visible layout params for later - see hideLayout() and showLayout()
            hiddenLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
                    ViewGroup.LayoutParams.WRAP_CONTENT);
            hiddenLayoutParams.height = 0;
            shownLayoutParams = new CardView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,

            //show the layout
            layout.setLayoutParams(shownLayoutParams);
        }

}

And I simply have an EditText as my search box:

cardsSearchTextView.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {

            }

            @Override
            public void afterTextChanged(Editable editable) {
                myViewAdapter.findObject(editable.toString().toLowerCase());
            }
        });

Result:

Since you're comparing numbers, you can use an arithmetic expression, which allows for simpler handling of parameters and comparison:

wget -q --tries=10 --timeout=20 --spider http://google.com
if (( $? != 0 )); then
    echo "Sorry you are Offline"
    exit 1
fi

Notice how instead of -ne, you can just use !=. In an arithmetic context, we don't even have to prepend $ to parameters, i.e.,

var_a=1
var_b=2
(( var_a < var_b )) && echo "a is smaller"

works perfectly fine. This doesn't appply to the $? special parameter, though.

Further, since (( ... )) evaluates non-zero values to true, i.e., has a return status of 0 for non-zero values and a return status of 1 otherwise, we could shorten to

if (( $? )); then

but this might confuse more people than the keystrokes saved are worth.

The (( ... )) construct is available in Bash, but not required by the POSIX shell specification (mentioned as possible extension, though).

This all being said, it's better to avoid $? altogether in my opinion, as in Cole's answer and Steven's answer.

For Python 3.7 or later,(2018-10-10), I have to combine both @Alejandro BR and SMNALLY's answer, coz @Alejandro forget to define wincl.

import os, os.path
import win32com.client
if os.path.exists('C:/Users/jz/Desktop/test.xlsm'):
    excel_macro = win32com.client.DispatchEx("Excel.Application") # DispatchEx is required in the newest versions of Python.
    excel_path = os.path.expanduser('C:/Users/jz/Desktop/test.xlsm')
    workbook = excel_macro.Workbooks.Open(Filename = excel_path, ReadOnly =1)
    excel_macro.Application.Run("test.xlsm!Module1.Macro1") # update Module1 with your module, Macro1 with your macro
    workbook.Save()
    excel_macro.Application.Quit()  
    del excel_macro

If you use PyCharm, please change you 'Project Interpreter' to '2.7.x'

Yes, there are at least 2 solutions for this:

1. Use the script directive (http://docs.angularjs.org/api/ng.directive:script) to put your partials in the initially loaded HTML
2. You could also fill in $templateCache (http://docs.angularjs.org/api/ng.$templateCache) from JavaScript if needed (possibly based on result of $http call)

If you would like to use method (2) to fill in $templateCache you can do it like this:

$templateCache.put('second.html', '<b>Second</b> template');

Of course the templates content could come from a $http call:

$http.get('third.html', {cache:$templateCache});

Here is the plunker those techniques: http://plnkr.co/edit/J6Y2dc?p=preview

I wrote a class to normalize the data in my dictionary. The 'element' in the NormalizeData class below, needs to be of dict type. And you need to replace in the __iterate() with either your custom class object or any other object type that you would like to normalize.

class NormalizeData:

    def __init__(self, element):
        self.element = element

    def execute(self):
        if isinstance(self.element, dict):
            self.__iterate()
        else:
            return

    def __iterate(self):
        for key in self.element:
            if isinstance(self.element[key], <ClassName>):
                self.element[key] = str(self.element[key])

            node = NormalizeData(self.element[key])
            node.execute()

One more solution as PyV8 seems to be unmaintained and dependent on the old version of libv8.

PyMiniRacer It's a wrapper around the v8 engine and it works with the new version and is actively maintained.

pip install py-mini-racer

from py_mini_racer import py_mini_racer
ctx = py_mini_racer.MiniRacer()
ctx.eval("""
function escramble_758(){
    var a,b,c
    a='+1 '
    b='84-'
    a+='425-'
    b+='7450'
    c='9'
    return a+c+b;
}
""")
ctx.call("escramble_758")

And yes, you have to replace document.write with return as others suggested

TL;DR: Use StandardError instead for general exception catching. When the original exception is re-raised (e.g. when rescuing to log the exception only), rescuing Exception is probably okay.

Exception is the root of Ruby's exception hierarchy, so when you rescue Exception you rescue from everything, including subclasses such as SyntaxError, LoadError, and Interrupt.

Rescuing Interrupt prevents the user from using CTRLC to exit the program.

Rescuing SignalException prevents the program from responding correctly to signals. It will be unkillable except by kill -9.

Rescuing SyntaxError means that evals that fail will do so silently.

All of these can be shown by running this program, and trying to CTRLC or kill it:

loop do
  begin
    sleep 1
    eval "djsakru3924r9eiuorwju3498 += 5u84fior8u8t4ruyf8ihiure"
  rescue Exception
    puts "I refuse to fail or be stopped!"
  end
end

Rescuing from Exception isn't even the default. Doing

begin
  # iceberg!
rescue
  # lifeboats
end

does not rescue from Exception, it rescues from StandardError. You should generally specify something more specific than the default StandardError, but rescuing from Exception broadens the scope rather than narrowing it, and can have catastrophic results and make bug-hunting extremely difficult.

If you have a situation where you do want to rescue from StandardError and you need a variable with the exception, you can use this form:

begin
  # iceberg!
rescue => e
  # lifeboats
end

which is equivalent to:

begin
  # iceberg!
rescue StandardError => e
  # lifeboats
end

One of the few common cases where it’s sane to rescue from Exception is for logging/reporting purposes, in which case you should immediately re-raise the exception:

begin
  # iceberg?
rescue Exception => e
  # do some logging
  raise # not enough lifeboats ;)
end

All of the previous answers are great. If it is a simple, one line sql command you wish to run, you could also use the -e option.

mysql -h <host> -u<user> -p<password> database -e \
  "SELECT * FROM blah WHERE foo='bar';"

To resolve the issue in Windows, the below steps work for me:

For example mongoDB version 3.6 is installed, and the install path of MongoDB is "D:\Program Files\MongoDB".

Create folder D:\mongodb\logs, then create file mongodb.log inside this folder.

Run cmd.exe as administrator,

D:\Program Files\MongoDB\Server\3.6\bin>taskkill /F /IM mongod.exe
D:\Program Files\MongoDB\Server\3.6\bin>mongod.exe --logpath D:\mongodb\logs\mongodb.log --logappend --dbpath D:\mongodb\data --directoryperdb --serviceName MongoDB --remove
D:\Program Files\MongoDB\Server\3.6\bin>mongod --logpath "D:\mongodb\logs\mongodb.log" --logappend --dbpath "D:\mongodb\data" --directoryperdb --serviceName "MongoDB" --serviceDisplayName "MongoDB" --install

Remove these two files mongod.lock and storage.bson under the folder "D:\mongodb\data".

Then type net start MongoDB in the cmd using administrator privilege, the issue will be solved.

The most upvoted Override push method solution by @canon has some side-effects that were inconvenient in my case:

• It makes the push property descriptor different (writable and configurable should be set true instead of false), which causes exceptions in a later point.

• It raises the event multiple times when push() is called once with multiple arguments (such as myArray.push("a", "b")), which in my case was unnecessary and bad for performance.

So this is the best solution I could find that fixes the previous issues and is in my opinion cleaner/simpler/easier to understand.

Object.defineProperty(myArray, "push", {
    configurable: true,
    enumerable: false,
    writable: true, // Previous values based on Object.getOwnPropertyDescriptor(Array.prototype, "push")
    value: function (...args)
    {
        let result = Array.prototype.push.apply(this, args); // Original push() implementation based on https://github.com/vuejs/vue/blob/f2b476d4f4f685d84b4957e6c805740597945cde/src/core/observer/array.js and https://github.com/vuejs/vue/blob/daed1e73557d57df244ad8d46c9afff7208c9a2d/src/core/util/lang.js

        RaiseMyEvent();

        return result; // Original push() implementation
    }
});

Please see comments for my sources and for hints on how to implement the other mutating functions apart from push: 'pop', 'shift', 'unshift', 'splice', 'sort', 'reverse'.

This is SUPER late and probably not relevant anymore, but if anyone stumbles upon this answer, I believe I know the cause.

So the JSON encoded string is perfectly valid with the degree symbol in it, as the other answer mentions. The problem is most likely in the character encoding that you are reading/writing with. Depending on how you are using Gson, you are probably passing it a java.io.Reader instance. Any time you are creating a Reader from an InputStream, you need to specify the character encoding, or java.nio.charset.Charset instance (it's usually best to use java.nio.charset.StandardCharsets.UTF_8). If you don't specify a Charset, Java will use your platform default encoding, which on Windows is usually CP-1252.

Super key is the combination of fields by which the row is uniquely identified and the candidate key is the minimal super key.

Another option like Gavin Palmer answer is to use the .pem file but with a curl option

1. download the last updated .pem file from https://curl.haxx.se/docs/caextract.html and save it somewhere on your server(outside the public folder)

2. set the option in your code instead of the php.ini file.

In your code

curl_setopt($ch, CURLOPT_CAINFO, $_SERVER['DOCUMENT_ROOT'] .  "/../cacert-2017-09-20.pem");

NOTE: setting the cainfo in the php.ini like @Gavin Palmer did is better than setting it in your code like I did, because it will save a disk IO every time the function is called, I just make it like this in case you want to test the cainfo file on the fly instead of changing the php.ini while testing your function.

While the indentation errors are obvious in the StackOverflow page, they may not be in your editor. You have a mix of different indentation types here, 1, 4 and 8 spaces. You should always use four spaces for indentation, as per PEP8. You should also avoid mixing tabs and spaces.

I also recommend that you try to run your script using the '-tt' command-line option to determine when you accidentally mix tabs and spaces. Of course any decent editor will be able to highlight tabs versus spaces (such as Vim's 'list' option).

For your specific case, just use the reduce method of Arrays:

var sumArray = function() {
    // Use one adding function rather than create a new one each
    // time sumArray is called
    function add(a, b) {
        return a + b;
    }

    return function(arr) {
        return arr.reduce(add);
    };
}();

alert( sumArray([2, 3, 4]) );

Good old readline();.

No it isn't possible.

You can get a generic type of a field given a class is the only exception to that rule and even that's a bit of a hack.

See Knowing type of generic in Java for an example of that.

JSON is just a subset of JavaScript. But eval evaluates the full JavaScript language and not just the subset that’s JSON.

The best on I have found is http://www.auditmypc.com/xml-sitemap.asp which uses Java, and has no limit on pages, and even lets you export results as a raw URL list.

It also uses sessions, so if you are using a CMS, make sure you are logged out before you run the crawl.

You might also be interested in Microsoft ClearScript which is hosted on GitHub and published under the Ms-Pl licence.

I am no Microsoft fanboy, but I must admit that the V8 support has about the same functionnalities as Javascript.Net, and more important, the project is still maintained. As far as I am concerned, the support for delegates also functions better than with Spidermonkey-dotnet.

ps: It also support JScript and VBScript but we were not interested by this old stuff.

ps: It is compatible with .NET 4.0 and 4.5+

Create a method in your class like this: [as @Holger said here.]

public static void clrscr(){
    //Clears Screen in java
    try {
        if (System.getProperty("os.name").contains("Windows"))
            new ProcessBuilder("cmd", "/c", "cls").inheritIO().start().waitFor();
        else
            Runtime.getRuntime().exec("clear");
    } catch (IOException | InterruptedException ex) {}
}

This works for windows at least, I have not checked for Linux so far. If anyone checks it for Linux please let me know if it works (or not).

As an alternate method is to write this code in clrscr():

for(int i = 0; i < 80*300; i++) // Default Height of cmd is 300 and Default width is 80
    System.out.print("\b"); // Prints a backspace

I will not recommend you to use this method.

You need to choose a Property to sort by and pass it as a lambda expression to OrderByDescending

like:

.OrderByDescending(x => x.Delivery.SubmissionDate);

Really, though the first version of your LINQ statement should work. Is t.Delivery.SubmissionDate actually populated with valid dates?

Use Math.Ceiling to round up

Math.Ceiling(0.5); // 1

Use Math.Round to just round

Math.Round(0.5, MidpointRounding.AwayFromZero); // 1

And Math.Floor to round down

Math.Floor(0.5); // 0

Use the MemoryStream class, calling Encoding.GetBytes to turn your string into an array of bytes first.

Do you subsequently need a TextReader on the stream? If so, you could supply a StringReader directly, and bypass the MemoryStream and Encoding steps.

Of all the suggestions, nobdy used the razor syntax (this is with bootstrap styles as well). This will make a button that redirects to the Login view in the Account controller:

    <form>
        <button class="btn btn-primary" asp-action="Login" asp- 
   controller="Account">@Localizer["Login"]</button>
    </form>

Also its working. In command form

cd C:\wamp\bin\mysql\mysql5.5.8\bin //hit enter
mysql -u -p databasename //-u=root,-p=blank

There are multiple function to do this work that wrote in bottom based on priority.

• .css()

Set one or more CSS properties for the set of matched elements.

$("div").css("display", "block")

// Or add multiple CSS properties
$("div").css({
  display: "block",
  color: "red",
  ...
})

• .show()

Display the matched elements and is roughly equivalent to calling .css("display", "block")

You can display element using .show() instead

$("div").show()

• .attr()

Set one or more attributes for the set of matched elements.

If target element hasn't style attribute, you can use this method to add inline style to element.

$("div").attr("style", "display:block")

// Or add multiple CSS properties
$("div").attr("style", "display:block; color:red")

• JavaScript

You can add specific CSS property to element using pure javascript, if you don't want to use jQuery.

var div = document.querySelector("div");
// One property
div.style.display = "block";
// Multiple properties
div.style.cssText = "display:block; color:red"; 
// Multiple properties
div.setAttribute("style", "display:block; color:red");

I prefer:

   xls.DisplayAlerts = False    
   wb.SaveAs fullFilePath, AccessMode:=xlExclusive, ConflictResolution:=xlLocalSessionChanges
   xls.DisplayAlerts = True

as Artyom said you need to use ngChange and pass ngModel object as argument to your ngChange function

Example:

<div ng-app="App" >
  <div ng-controller="ctrl">
    <select ng-model="blisterPackTemplateSelected" ng-change="changedValue(blisterPackTemplateSelected)" 
            data-ng-options="blisterPackTemplate as blisterPackTemplate.name for blisterPackTemplate in blisterPackTemplates">
      <option value="">Select Account</option>
    </select>
    {{itemList}}     
  </div>       
</div>

js:

function ctrl($scope) {
  $scope.itemList = [];
  $scope.blisterPackTemplates = [{id:1,name:"a"},{id:2,name:"b"},{id:3,name:"c"}];

  $scope.changedValue = function(item) {
    $scope.itemList.push(item.name);
  }       
}

What you want to do is a combination of part of 1 and all of 2.

You need to use the PowerMockito.mockStatic to enable static mocking for all static methods of a class. This means make it possible to stub them using the when-thenReturn syntax.

But the 2-argument overload of mockStatic you are using supplies a default strategy for what Mockito/PowerMock should do when you call a method you haven't explicitly stubbed on the mock instance.

From the javadoc:

Creates class mock with a specified strategy for its answers to interactions. It's quite advanced feature and typically you don't need it to write decent tests. However it can be helpful when working with legacy systems. It is the default answer so it will be used only when you don't stub the method call.

The default default stubbing strategy is to just return null, 0 or false for object, number and boolean valued methods. By using the 2-arg overload, you're saying "No, no, no, by default use this Answer subclass' answer method to get a default value. It returns a Long, so if you have static methods which return something incompatible with Long, there is a problem.

Instead, use the 1-arg version of mockStatic to enable stubbing of static methods, then use when-thenReturn to specify what to do for a particular method. For example:

import static org.mockito.Mockito.*;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.invocation.InvocationOnMock;
import org.mockito.stubbing.Answer;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

class ClassWithStatics {
  public static String getString() {
    return "String";

The String-valued static method is stubbed to return "Hello!", while the int-valued static method uses the default stubbing, returning 0.

In all schemas:

=> \dt *.*

In a particular schema:

=> \dt public.*

It is possible to use regular expressions with some restrictions

\dt (public|s).(s|t)
       List of relations
 Schema | Name | Type  | Owner 
--------+------+-------+-------
 public | s    | table | cpn
 public | t    | table | cpn
 s      | t    | table | cpn

Advanced users can use regular-expression notations such as character classes, for example [0-9] to match any digit. All regular expression special characters work as specified in Section 9.7.3, except for . which is taken as a separator as mentioned above, * which is translated to the regular-expression notation .*, ? which is translated to ., and $ which is matched literally. You can emulate these pattern characters at need by writing ? for ., (R+|) for R*, or (R|) for R?. $ is not needed as a regular-expression character since the pattern must match the whole name, unlike the usual interpretation of regular expressions (in other words, $ is automatically appended to your pattern). Write * at the beginning and/or end if you don't wish the pattern to be anchored. Note that within double quotes, all regular expression special characters lose their special meanings and are matched literally. Also, the regular expression special characters are matched literally in operator name patterns (i.e., the argument of \do).

I disagree that .form-group should be within .col-*-n elements. In my experience, all the appropriate padding happens automatically when you use .form-group like .row within a form.

<div class="form-group">
    <div class="col-sm-12">
        <label for="user_login">Username</label>
        <input class="form-control" id="user_login" name="user[login]" required="true" size="30" type="text" />
    </div>
</div>

Check out this demo.

Altering the demo slightly by adding .form-horizontal to the form tag changes some of that padding.

<form action="#" method="post" class="form-horizontal">

Check out this demo.

When in doubt, inspect in Chrome or use Firebug in Firefox to figure out things like padding and margins. Using .row within the form fails in edsioufi's fiddle because .row uses negative left and right margins thereby drawing the horizontal bounds of the divs classed .row beyond the bounds of the containing fieldsets.

this seems to work on our site, using your ideas and a little math based upon the left edge of wrapper div. It seems redundant to go left 50% then take out 50% extra margin, but it seems to work.

div.ImgWrapper {
    width: 160px;
    height: 160px
    overflow: hidden;
    text-align: center;
}

img.CropCenter {
    left: 50%;
    margin-left: -100%;
    position: relative;
    width: auto !important;
    height: 160px !important;
}

<div class="ImgWrapper">
<a href="#"><img class="CropCenter" src="img.png"></a>
</div>

I got your problem , and here is my answer:

prices = [5, 12, 45]
list=['1','2','3']

for i in range(1,3):
  vars()["prices"+list[0]]=prices[0]
print ("prices[i]=" +prices[i])

so while printing:

price1 = 5 
price2 = 12
price3 = 45

More generic approatch using JQuery library closest() and submit() buttons. Here you do not have to specify whitch form you want to submit, submits the form it is in.

<a href="#" onclick="$(this).closest('form').submit()">Submit Link</a>

I faced the same issue. Just download and install the SQL Server suite from the following link :http://www.microsoft.com/en-US/download/details.aspx?id=42299

restart your SSMS and you should be able to "Register Local Servers" via right-click on "Local Servers Groups", select "tasks", click "register local servers"

My requirements are the camera preview need to be fullscreen and keep the aspect ratio. Hesam and Yoosuf's solution was great but I do see a high zoom problem for some reason.

The idea is the same, have the preview container center in parent and increase the width or height depend on the aspect ratios until it can cover the entire screen.

One thing to note is the preview size is in landscape because we set the display orientation.

camera.setDisplayOrientation(90);

The container that we will add the SurfaceView view to:

<RelativeLayout
    android:id="@+id/camera_preview_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_centerInParent="true"/>

Add the preview to it's container with center in parent in your activity.

this.cameraPreview = new CameraPreview(this, camera);
cameraPreviewContainer.removeAllViews();
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(
    ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
params.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
cameraPreviewContainer.addView(cameraPreview, 0, params);

Inside the CameraPreview class:

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
    // If your preview can change or rotate, take care of those events here.
    // Make sure to stop the preview before resizing or reformatting it.

    if (holder.getSurface() == null) {
        // preview surface does not exist
        return;
    }

    stopPreview();

    // set preview size and make any resize, rotate or
    // reformatting changes here
    try {
        Camera.Size nativePictureSize = CameraUtils.getNativeCameraPictureSize(camera);
        Camera.Parameters parameters = camera.getParameters();
        parameters.setPreviewSize(optimalSize.width, optimalSize.height);
        parameters.setPictureSize(nativePictureSize.width, nativePictureSize.height);
        camera.setParameters(parameters);
        camera.setDisplayOrientation(90);
        camera.setPreviewDisplay(holder);
        camera.startPreview();

    } catch (Exception e){
        Log.d(TAG, "Error starting camera preview: " + e.getMessage());
    }
}

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
    final int width = resolveSize(getSuggestedMinimumWidth(), widthMeasureSpec);
    final int height = resolveSize(getSuggestedMinimumHeight(), heightMeasureSpec);

    if (supportedPreviewSizes != null && optimalSize == null) {
        optimalSize = CameraUtils.getOptimalSize(supportedPreviewSizes, width, height);
        Log.i(TAG, "optimal size: " + optimalSize.width + "w, " + optimalSize.height + "h");
    }

    float previewRatio =  (float) optimalSize.height / (float) optimalSize.width;
    // previewRatio is height/width because camera preview size are in landscape.
    float measuredSizeRatio = (float) width / (float) height;

    if (previewRatio >= measuredSizeRatio) {
        measuredHeight = height;
        measuredWidth = (int) ((float)height * previewRatio);
    } else {
        measuredWidth = width;
        measuredHeight = (int) ((float)width / previewRatio);
    }
    Log.i(TAG, "Preview size: " + width + "w, " + height + "h");
    Log.i(TAG, "Preview size calculated: " + measuredWidth + "w, " + measuredHeight + "h");

    setMeasuredDimension(measuredWidth, measuredHeight);
}

Update: while the following solution works, there's a much easier method. See below.

Here's what I came up with, and I hope this comes in handy - to you or anybody else:

$('#element').attr('style', function(i, style)
{
    return style && style.replace(/display[^;]+;?/g, '');
});

This will remove that inline style.

I'm not sure this is what you wanted. You wanted to override it, which, as pointed out already, is easily done by $('#element').css('display', 'inline').

What I was looking for was a solution to REMOVE the inline style completely. I need this for a plugin I'm writing where I have to temporarily set some inline CSS values, but want to later remove them; I want the stylesheet to take back control. I could do it by storing all of its original values and then putting them back inline, but this solution feels much cleaner to me.

Here it is in plugin format:

(function($)
{
    $.fn.removeStyle = function(style)
    {
        var search = new RegExp(style + '[^;]+;?', 'g');

        return this.each(function()
        {
            $(this).attr('style', function(i, style)
            {
                return style && style.replace(search, '');
            });
        });
    };
}(jQuery));

If you include this plugin in the page before your script, you can then just call

$('#element').removeStyle('display');

and that should do the trick.

Update: I now realized that all this is futile. You can simply set it to blank:

$('#element').css('display', '');

and it'll automatically be removed for you.

Here's a quote from the docs:

Setting the value of a style property to an empty string — e.g. $('#mydiv').css('color', '') — removes that property from an element if it has already been directly applied, whether in the HTML style attribute, through jQuery's .css() method, or through direct DOM manipulation of the style property. It does not, however, remove a style that has been applied with a CSS rule in a stylesheet or <style> element.

I don't think jQuery is doing any magic here; it seems the style object does this natively.

Default Export (export default)

// MyClass.ts -- using default export
export default class MyClass { /* ... */ }

The main difference is that you can only have one default export per file and you import it like so:

import MyClass from "./MyClass";

You can give it any name you like. For example this works fine:

import MyClassAlias from "./MyClass";

Named Export (export)

// MyClass.ts -- using named exports
export class MyClass { /* ... */ }
export class MyOtherClass { /* ... */ }

When you use a named export, you can have multiple exports per file and you need to import the exports surrounded in braces:

import { MyClass } from "./MyClass";

Note: Adding the braces will fix the error you're describing in your question and the name specified in the braces needs to match the name of the export.

Or say your file exported multiple classes, then you could import both like so:

import { MyClass, MyOtherClass } from "./MyClass";
// use MyClass and MyOtherClass

Or you could give either of them a different name in this file:

import { MyClass, MyOtherClass as MyOtherClassAlias } from "./MyClass";
// use MyClass and MyOtherClassAlias

Or you could import everything that's exported by using * as:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass and MyClasses.MyOtherClass here

Which to use?

In ES6, default exports are concise because their use case is more common; however, when I am working on code internal to a project in TypeScript, I prefer to use named exports instead of default exports almost all the time because it works very well with code refactoring. For example, if you default export a class and rename that class, it will only rename the class in that file and not any of the other references in other files. With named exports it will rename the class and all the references to that class in all the other files.

It also plays very nicely with barrel files (files that use namespace exports—export *—to export other files). An example of this is shown in the "example" section of this answer.

Note that my opinion on using named exports even when there is only one export is contrary to the TypeScript Handbook—see the "Red Flags" section. I believe this recommendation only applies when you are creating an API for other people to use and the code is not internal to your project. When I'm designing an API for people to use, I'll use a default export so people can do import myLibraryDefaultExport from "my-library-name";. If you disagree with me about doing this, I would love to hear your reasoning.

That said, find what you prefer! You could use one, the other, or both at the same time.

Additional Points

A default export is actually a named export with the name default, so if the file has a default export then you can also import by doing:

import { default as MyClass } from "./MyClass";

And take note these other ways to import exist: 

import MyDefaultExportedClass, { Class1, Class2 } from "./SomeFile";
import MyDefaultExportedClass, * as Classes from "./SomeFile";
import "./SomeFile"; // runs SomeFile.js without importing any exports

It's easy to detect the image orientation and replace the bitmap using:

 /**
 * Rotate an image if required.
 * @param img
 * @param selectedImage
 * @return
 */
private static Bitmap rotateImageIfRequired(Context context,Bitmap img, Uri selectedImage) {

    // Detect rotation
    int rotation = getRotation(context, selectedImage);
    if (rotation != 0) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotation);
        Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
        img.recycle();
        return rotatedImg;
    }
    else{
        return img;
    }
}

/**
 * Get the rotation of the last image added.
 * @param context
 * @param selectedImage
 * @return
 */
private static int getRotation(Context context,Uri selectedImage) {

    int rotation = 0;
    ContentResolver content = context.getContentResolver();

    Cursor mediaCursor = content.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                                       new String[] { "orientation", "date_added" },
                                       null, null, "date_added desc");

    if (mediaCursor != null && mediaCursor.getCount() != 0) {
        while(mediaCursor.moveToNext()){
            rotation = mediaCursor.getInt(0);
            break;
        }
    }
    mediaCursor.close();
    return rotation;
}

To avoid Out of memories with big images, I'd recommend you to rescale the image using:

private static final int MAX_HEIGHT = 1024;
private static final int MAX_WIDTH = 1024;
public static Bitmap decodeSampledBitmap(Context context, Uri selectedImage)
    throws IOException {

    // First decode with inJustDecodeBounds=true to check dimensions
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inJustDecodeBounds = true;
    InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
    BitmapFactory.decodeStream(imageStream, null, options);
    imageStream.close();

    // Calculate inSampleSize
    options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);

    // Decode bitmap with inSampleSize set
    options.inJustDecodeBounds = false;
    imageStream = context.getContentResolver().openInputStream(selectedImage);
    Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);

    img = rotateImageIfRequired(img, selectedImage);
    return img;
}

It's not posible to use ExifInterface to get the orientation because an Android OS issue: https://code.google.com/p/android/issues/detail?id=19268

And here is calculateInSampleSize

/**
 * Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
 * bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates
 * the closest inSampleSize that will result in the final decoded bitmap having a width and
 * height equal to or larger than the requested width and height. This implementation does not
 * ensure a power of 2 is returned for inSampleSize which can be faster when decoding but
 * results in a larger bitmap which isn't as useful for caching purposes.
 *
 * @param options   An options object with out* params already populated (run through a decode*
 *                  method with inJustDecodeBounds==true
 * @param reqWidth  The requested width of the resulting bitmap
 * @param reqHeight The requested height of the resulting bitmap
 * @return The value to be used for inSampleSize
 */
public static int calculateInSampleSize(BitmapFactory.Options options,
                                        int reqWidth, int reqHeight) {

    // Raw height and width of image
    final int height = options.outHeight;
    final int width = options.outWidth;
    int inSampleSize = 1;

    if (height > reqHeight || width > reqWidth) {

        // Calculate ratios of height and width to requested height and width
        final int heightRatio = Math.round((float) height / (float) reqHeight);
        final int widthRatio = Math.round((float) width / (float) reqWidth);

        // Choose the smallest ratio as inSampleSize value, this will guarantee a final image
        // with both dimensions larger than or equal to the requested height and width.
        inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;

        // This offers some additional logic in case the image has a strange
        // aspect ratio. For example, a panorama may have a much larger
        // width than height. In these cases the total pixels might still
        // end up being too large to fit comfortably in memory, so we should
        // be more aggressive with sample down the image (=larger inSampleSize).

        final float totalPixels = width * height;

        // Anything more than 2x the requested pixels we'll sample down further
        final float totalReqPixelsCap = reqWidth * reqHeight * 2;

        while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
            inSampleSize++;
        }
    }
    return inSampleSize;
}

Remove the onchange event from the HTML Markup and bind it in your document ready event

<select  name="a[b]" >
     <option value='Choice 1'>Choice 1</option>
     <option value='Choice 2'>Choice 2</option>
</select>?

and Script

$(function(){    
    $("select[name='a[b]']").change(function(){
       alert($(this).val());        
    }); 
});

Working sample : http://jsfiddle.net/gLaR8/3/

table { 
  border-spacing: 10px; 
} 

This worked for me once I removed

border-collapse: separate;

from my table tag.

I think this will cover any possible scenario for what is in O10:

=IF(ISBLANK(O10),"",IF(O10<TODAY(),IF(TODAY()-O10<>1,CONCATENATE("Due in ",TEXT(TODAY()-O10,"d")," days"),CONCATENATE("Due in ",TEXT(TODAY()-O10,"d")," day")),IF(O10=TODAY(),"Due Today","Overdue")))

For Dates that are before Today, it will tell you how many days the item is due in. If O10 = Today then it will say "Due Today". Anything past Today and it will read overdue. Lastly, if it is blank, the cell will also appear blank. Let me know what you think!

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

You can do this in-place, rather than create a new dict, which may be preferable for large dictionaries (if you do not need a copy).

def mutate_dict(f,d):
    for k, v in d.iteritems():
        d[k] = f(v)

my_dictionary = {'a':1, 'b':2}
mutate_dict(lambda x: x+1, my_dictionary)

results in my_dictionary containing:

{'a': 2, 'b': 3}

A little extension to the above answers. The trailing > directs the input into the file, overwriting existing content. However, one particularly convenient use is the double arrow >> that appends, adding your new content to the end of the file, as in:

cat <<EOF >> /etc/fstab
data_server:/var/sharedServer/authority/cert /var/sharedFolder/sometin/authority/cert nfs
data_server:/var/sharedServer/cert   /var/sharedFolder/sometin/vsdc/cert nfs
EOF

This extends your fstab without you having to worry about accidentally modifying any of its contents.

As other said, the comment in XML are like this

<!-- this is a comment -->

Notice that they can span on multiple lines

<!--

But they cannot be nested

<!-- This <!-- is a comment --> This is not -->

Also you cannot use them inside tags

<EditText <!--This is not valid--> android:layout_width="fill_parent" />

Set the style on the textbox as text-transform: uppercase?

RuntimeHelpers.GetHashCode() may help (MSDN).

it works, all you need:

PHP:

header('Access-Control-Allow-Origin: http://www.example.com');
header("Access-Control-Allow-Credentials: true");
header('Access-Control-Allow-Methods: GET, PUT, POST, DELETE, OPTIONS');

JS (jQuery ajax):

var getWBody = $.ajax({ cache: false,
        url: URL,
        dataType : 'json',
        type: 'GET',
        xhrFields: { withCredentials: true }
});

In addition to the above, you can do this (where "YourListObjectName" is the name of your table):

Dim LO As ListObject
Set LO = ActiveSheet.ListObjects("YourListObjectName")

But I think that only works if you want to reference a list object that's on the active sheet.

I found your question because I wanted to refer to a list object (a table) on one worksheet that a pivot table on a different worksheet refers to. Since list objects are part of the Worksheets collection, you have to know the name of the worksheet that list object is on in order to refer to it. So to get the name of the worksheet that the list object is on, I got the name of the pivot table's source list object (again, a table) and looped through the worksheets and their list objects until I found the worksheet that contained the list object I was looking for.

Public Sub GetListObjectWorksheet()

Maybe someone knows a more direct way.

Correct expression is

"source " + (DT_STR,4,1252)DATEPART( "yyyy" , getdate() ) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "mm" , getdate() ), 2) + "-" +
RIGHT("0" + (DT_STR,4,1252)DATEPART( "dd" , getdate() ), 2) +".CSV"

use command npm init -f to generate package.json file and after that use --save after each command so that each module will automatically get updated inside your package.json for ex: npm install express --save

Use the dec argument to set "," as the decimal point by adding:

 ce <- read.table("file.txt", header = TRUE, dec = ",")

Firstly, of all I recommend that the pictures are in the same folder as the workbook. You need to enter some codes in the Worksheet_Change procedure of the worksheet. For example, we can enter the following codes to add the image that with the same name as the value of cell in column A to the cell in column D:

Private Sub Worksheet_Change(ByVal Target As Range)
Dim pic As Picture
If Intersect(Target, [A:A]) Is Nothing Then Exit Sub
On Error GoTo son

For Each pic In ActiveSheet.Pictures
    If Not Application.Intersect(pic.TopLeftCell, Range(Target.Offset(0, 3).Address)) Is Nothing Then
        pic.Delete
    End If
Next pic

ActiveSheet.Pictures.Insert(ThisWorkbook.Path & "\" & Target.Value & ".jpg").Select
Selection.Top = Target.Offset(0, 2).Top
Selection.Left = Target.Offset(0, 3).Left
Selection.ShapeRange.LockAspectRatio = msoFalse
Selection.ShapeRange.Height = Target.Offset(0, 2).Height
Selection.ShapeRange.Width = Target.Offset(0, 3).Width
son:

End Sub

With the codes above, the picture is sized according to the cell it is added to.

If elements of array are also simple objects or arrays, you can use some function:

// search object
var element = { item:'book', title:'javasrcipt'};

[{ item:'handbook', title:'c++'}, { item:'book', title:'javasrcipt'}].some(function(el){
    if( el.item === element.item && el.title === element.title ){
        return true; 
     } 
});

[['handbook', 'c++'], ['book', 'javasrcipt']].some(function(el){
    if(el[0] == element.item && el[1] == element.title){
        return true;
    }
});

My solution using standard <ul> and <i> inside <li>

  <ul>
    <li><i class="fab fa-cc-paypal"></i> <div>Paypal</div></li>
    <li><i class="fab fa-cc-apple-pay"></i> <div>Apple Pay</div></li>
    <li><i class="fab fa-cc-stripe"></i> <div>Stripe</div></li>
    <li><i class="fab fa-cc-visa"></i> <div>VISA</div></li>
  </ul>

Modified this to be a lot more accurate. It will convert dates to a 'YYYY-MM-DD' format, ignoring HH:MM:SS, and takes an optional endDate or uses the current date, and doesn't care about the order of the values.

function dateDiff(startingDate, endingDate) {
    var startDate = new Date(new Date(startingDate).toISOString().substr(0, 10));
    if (!endingDate) {
        endingDate = new Date().toISOString().substr(0, 10);    // need date in YYYY-MM-DD format
    }
    var endDate = new Date(endingDate);
    if (startDate > endDate) {
        var swap = startDate;
        startDate = endDate;
        endDate = swap;
    }
    var startYear = startDate.getFullYear();
    var february = (startYear % 4 === 0 && startYear % 100 !== 0) || startYear % 400 === 0 ? 29 : 28;
    var daysInMonth = [31, february, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];

    var yearDiff = endDate.getFullYear() - startYear;
    var monthDiff = endDate.getMonth() - startDate.getMonth();
    if (monthDiff < 0) {
        yearDiff--;
        monthDiff += 12;
    }
    var dayDiff = endDate.getDate() - startDate.getDate();
    if (dayDiff < 0) {
        if (monthDiff > 0) {
            monthDiff--;
        } else {
            yearDiff--;
            monthDiff = 11;
        }
        dayDiff += daysInMonth[startDate.getMonth()];
    }

    return yearDiff + 'Y ' + monthDiff + 'M ' + dayDiff + 'D';
}

Then you can use it like this:

// based on a current date of 2019-05-10
dateDiff('2019-05-10'); // 0Y 0M 0D
dateDiff('2019-05-09'); // 0Y 0M 1D
dateDiff('2018-05-09'); // 1Y 0M 1D
dateDiff('2018-05-18'); // 0Y 11M 23D
dateDiff('2019-01-09'); // 0Y 4M 1D
dateDiff('2019-02-10'); // 0Y 3M 0D
dateDiff('2019-02-11'); // 0Y 2M 27D
dateDiff('2016-02-11'); // 3Y 2M 28D - leap year
dateDiff('1972-11-30'); // 46Y 5M 10D
dateDiff('2016-02-11', '2017-02-11'); // 1Y 0M 0D
dateDiff('2016-02-11', '2016-03-10'); // 0Y 0M 28D - leap year
dateDiff('2100-02-11', '2100-03-10'); // 0Y 0M 27D - not a leap year
dateDiff('2017-02-11', '2016-02-11'); // 1Y 0M 0D - swapped dates to return correct result
dateDiff(new Date() - 1000 * 60 * 60 * 24); // 0Y 0M 1D

Older less accurate but simpler version

@RajeevPNadig's answer was what I was looking for, but his code returns incorrect values as written. This is not very accurate because it assumes that the sequence of dates from 1 January 1970 is the same as any other sequence of the same number of days. E.g. it calculates the difference from 1 July to 1 September (62 days) as 0Y 2M 3D and not 0Y 2M 0D because 1 Jan 1970 plus 62 days is 3 March.

// startDate must be a date string
function dateAgo(date) {
    var startDate = new Date(date);
    var diffDate = new Date(new Date() - startDate);
    return ((diffDate.toISOString().slice(0, 4) - 1970) + "Y " +
        diffDate.getMonth() + "M " + (diffDate.getDate()-1) + "D");
}

Then you can use it like this:

// based on a current date of 2018-03-09
dateAgo('1972-11-30'); // "45Y 3M 9D"
dateAgo('2017-03-09'); // "1Y 0M 0D"
dateAgo('2018-01-09'); // "0Y 2M 0D"
dateAgo('2018-02-09'); // "0Y 0M 28D" -- a little odd, but not wrong
dateAgo('2018-02-01'); // "0Y 1M 5D" -- definitely "feels" wrong
dateAgo('2018-03-09'); // "0Y 0M 0D"

If your use case is just date strings, then this works okay if you just want a quick and dirty 4 liner.

I didn't mean to answer my own question but I just thought about running a sitemap generator. First one I found http://www.xml-sitemaps.com has a nice text output. Perfect for my needs.

The exec system call of the Linux kernel understands shebangs (#!) natively

When you do on bash:

./something

on Linux, this calls the exec system call with the path ./something.

This line of the kernel gets called on the file passed to exec: https://github.com/torvalds/linux/blob/v4.8/fs/binfmt_script.c#L25

if ((bprm->buf[0] != '#') || (bprm->buf[1] != '!'))

It reads the very first bytes of the file, and compares them to #!.

If the comparison is true, then the rest of the line is parsed by the Linux kernel, which makes another exec call with path /usr/bin/python3 and current file as the first argument:

/usr/bin/python3 /path/to/script.py

and this works for any scripting language that uses # as a comment character.

And analogously, if you decide to use env instead, which you likely should always do to work on systems that have the python3 in a different location, notably pyenv, see also this question, the shebang:

#!/usr/bin/env python3

ends up calling analogously:

/usr/bin/env python3 /path/to/script.py

which does what you expect from env python3: searches PATH for python3 and runs /usr/bin/python3 /path/to/script.py.

And yes, you can make an infinite loop with:

printf '#!/a\n' | sudo tee /a
sudo chmod +x /a
/a

Bash recognizes the error:

-bash: /a: /a: bad interpreter: Too many levels of symbolic links

#! just happens to be human readable, but that is not required.

If the file started with different bytes, then the exec system call would use a different handler. The other most important built-in handler is for ELF executable files: https://github.com/torvalds/linux/blob/v4.8/fs/binfmt_elf.c#L1305 which checks for bytes 7f 45 4c 46 (which also happens to be human readable for .ELF). Let's confirm that by reading the 4 first bytes of /bin/ls, which is an ELF executable:

head -c 4 "$(which ls)" | hd 

output:

00000000  7f 45 4c 46                                       |.ELF|
00000004                                                                 

So when the kernel sees those bytes, it takes the ELF file, puts it into memory correctly, and starts a new process with it. See also: How does kernel get an executable binary file running under linux?

Finally, you can add your own shebang handlers with the binfmt_misc mechanism. For example, you can add a custom handler for .jar files. This mechanism even supports handlers by file extension. Another application is to transparently run executables of a different architecture with QEMU.

I don't think POSIX specifies shebangs however: https://unix.stackexchange.com/a/346214/32558 , although it does mention in on rationale sections, and in the form "if executable scripts are supported by the system something may happen". macOS and FreeBSD also seem to implement it however.

PATH search motivation

Likely, one big motivation for the existence of shebangs is the fact that in Linux, we often want to run commands from PATH just as:

basename-of-command

instead of:

/full/path/to/basename-of-command

But then, without the shebang mechanism, how would Linux know how to launch each type of file?

Hardcoding the extension in commands:

 basename-of-command.py

or implementing PATH search on every interpreter:

python3 basename-of-command

would be a possibility, but this has the major problem that everything breaks if we ever decide to refactor the command into another language.

Shebangs solve this problem beautifully.

See also: Why do people write #!/usr/bin/env python on the first line of a Python script?

you can save the original queue to a temporary queue. Then you simply do your normal pop on the temporary queue to go through the original one, for example:

queue tmp_q = original_q; //copy the original queue to the temporary queue

while (!tmp_q.empty())
{
    q_element = tmp_q.front();
    std::cout << q_element <<"\n";
    tmp_q.pop();
} 

At the end, the tmp_q will be empty but the original queue is untouched.

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

That's only two simple commands, but I wouldn't recommend this, unless the files that you DON'T need to copy are small. That's because this will copy ALL files and then remove the files that are not needed in the copy.

xcopy /E /I folder1 copy_of_folder1
for /F "tokens=1 delims=" %i in ('dir /B /S /A:-D copy_of_files ^| find /V "info.txt" ^| find /V "data.zip"') do del /Q "%i"

Sure, the second command is kind of long, but it works!

Also, this approach doesn't require you to download and install any third party tools (Windows 2000+ BATCH has enough commands for this).

In some languages True is just and alias for the number. You can learn more why this is by reading more about boolean logic.

There are a couple of things wrong in this code:

1. You're using <input> the wrong way. You should use a <label> if you want to make the text behind it clickable.
2. It's setting the enabled attribute, which does not exist. Use disabled instead.
3. If it would be an attribute, it's value should not be false, use disabled="disabled" or simply disabled without a value.
4. If checking for someone clicking on a form event that will CHANGE it's value (like check-boxes and radio-buttons), use .change() instead.

I'm not sure what your code is supposed to do. My guess is that you want to disable the input field with class roomNumber once someone selects "Walk in" (and possibly re-enable when deselected). If so, try this code:

HTML:

<form class="type">
    <p>
        <input type="radio" name="type" checked="checked" id="guest" value="guest" />
        <label for="guest">In House</label>
    </p>
    <p>
        <input type="radio" name="type" id="walk_in" value="walk_in" />
        <label for="walk_in">Walk in</label>
    </p>
    <p>
        <input type="text" name="roomnumber" class="roomNumber" value="12345" />
    </p>
</form>

Javascript:

$("form input:radio").change(function () {
    if ($(this).val() == "walk_in") {
        // Disable your roomnumber element here
        $('.roomNumber').attr('disabled', 'disabled');
    } else {
        // Re-enable here I guess
        $('.roomNumber').removeAttr('disabled');
    }
});

I created a fiddle here: http://jsfiddle.net/k28xd/1/

Axes sizing in MATLAB can be a bit tricky sometimes. You are correct to suspect the paper sizing properties as one part of the problem. Another is the automatic margins MATLAB calculates. Fortunately, there are settable axes properties that allow you to circumvent these margins. You can reset the margins to be just big enough for axis labels using a combination of the Position and TightInset properties which are explained here. Try this:

>> h = figure;
>> axes;
>> set(h, 'InvertHardcopy', 'off');
>> saveas(h, 'WithMargins.pdf');

and you'll get a PDF that looks like: but now do this:

>> tightInset = get(gca, 'TightInset');
>> position(1) = tightInset(1);
>> position(2) = tightInset(2);
>> position(3) = 1 - tightInset(1) - tightInset(3);
>> position(4) = 1 - tightInset(2) - tightInset(4);
>> set(gca, 'Position', position);
>> saveas(h, 'WithoutMargins.pdf');

and you'll get:

//Your broadcast in service

(function () { 
    angular.module('appModule').factory('AppService', function ($rootScope, $timeout) {

    function refreshData() {  
        $timeout(function() {         
            $rootScope.$broadcast('refreshData');
        }, 0, true);      
    }

    return {           
        RefreshData: refreshData
    };
}); }());

//Controller Implementation
 (function () {
    angular.module('appModule').controller('AppController', function ($rootScope, $scope, $timeout, AppService) {            

       //Removes Listeners before adding them 
       //This line will solve the problem for multiple broadcast call                             
       $scope.$$listeners['refreshData'] = [];

       $scope.$on('refreshData', function() {                                                    
          $scope.showData();             
       });

       $scope.onSaveDataComplete = function() { 
         AppService.RefreshData();
       };
    }); }());

The author of this post (now deleted post) suggests checking your C:\Windows\System32 folder to make sure that the oci.dll exists there. Copying in the file from the Oracle home directory solved this problem for me.

It looks like the one-liner got even simpler along the line (currently using R 3.5.3):

# generate original data.frame
df <- data.frame(a = letters[1:10], b = 1:10, c = LETTERS[1:10])
# use first column for row names
df <- data.frame(df, row.names = 1)

The column used for row names is removed automatically.

1. Right-click on the tables node and choose New Table...
2. With the table designer open, open the properties window (view -> Properties Window).
3. You can change the schema that the table will be made in by choosing a schema in the properties window.

You can do this from the template with something like this:

{% if form.instance.some_field %}
      {{form.instance.some_field}}
{% else %}
      {{form.data.some_field}}
{% endif %}

This will display the instance value (if the form is created with an instance, you can use initial instead if you like), or else display the POST data such as when a validation error occurs.

If you have an instance function (i.e. one that gets passed self) you can use self to get a reference to the class using self.__class__

For example in the code below tornado creates an instance to handle get requests, but we can get hold of the get_handler class and use it to hold a riak client so we do not need to create one for every request.

import tornado.web
import riak

class get_handler(tornado.web.requestHandler):
    riak_client = None

    def post(self):
        cls = self.__class__
        if cls.riak_client is None:
            cls.riak_client = riak.RiakClient(pb_port=8087, protocol='pbc')
        # Additional code to send response to the request ...
    

If you don't want it to add it to a link, you can just enclose it within a span and that would work.

<span id='clickableAwesomeFont'><i class="fa fa-behance-square fa-4x"></span>

in your css, then you can:

#clickableAwesomeFont {
     cursor: pointer
}

Then in java script, you can just add a click handler.

In cases where it's actually not a link, I think this is much cleaner and using a link would be changing its semantics and abusing its meaning.

I found an important step to add to this - after you've installed the SDK, go to your project properties and change Configuration Properties->General->Platform Toolset from v100 or whatever it is to Windows7.1SDK. This changes $(WindowsSdkDir) to the proper place and seemed to solve some other difficulties I was encountering as well.

In swift 3

let nextVC = self.storyboard?.instantiateViewController(withIdentifier: "NextViewController") as! NextViewController        
self.navigationController?.pushViewController(nextVC, animated: true)

This is caused by the path length restriction. I think it's 256 characters maximum.

Relocate your project and the build will succeed.

First, I would like to clarify something. Is this a post back (trip back to server) never occur, or is it the post back occurs, but it never gets into the ddlCountry_SelectedIndexChanged event handler?

I am not sure which case you are having, but if it is the second case, I can offer some suggestion. If it is the first case, then the following is FYI.

For the second case (event handler never fires even though request made), you may want to try the following suggestions:

1. Query the Request.Params[ddlCountries.UniqueID] and see if it has value. If it has, manually fire the event handler.
2. As long as view state is on, only bind the list data when it is not a post back.
3. If view state has to be off, then put the list data bind in OnInit instead of OnLoad.

Beware that when calling Control.DataBind(), view state and post back information would no longer be available from the control. In the case of view state is on, between post back, values of the DropDownList would be kept intact (the list does not to be rebound). If you issue another DataBind in OnLoad, it would clear out its view state data, and the SelectedIndexChanged event would never be fired.

In the case of view state is turned off, you have no choice but to rebind the list every time. When a post back occurs, there are internal ASP.NET calls to populate the value from Request.Params to the appropriate controls, and I suspect happen at the time between OnInit and OnLoad. In this case, restoring the list values in OnInit will enable the system to fire events correctly.

Thanks for your time reading this, and welcome everyone to correct if I am wrong.

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

Use -C option of tar:

tar zxvf <yourfile>.tar.gz -C /usr/src/

and then, the content of the tar should be in:

/usr/src/<yourfile>

Wasn't sure if you meant which Oracle users can read\write with the directory or the correlation of the permissions between Oracle Directory Object and the underlying Operating System Directory.

As DCookie has covered the Oracle side of the fence, the following is taken from the Oracle documentation found here.

Privileges granted for the directory are created independently of the permissions defined for the operating system directory, and the two may or may not correspond exactly. For example, an error occurs if sample user hr is granted READ privilege on the directory object but the corresponding operating system directory does not have READ permission defined for Oracle Database processes.

With props to Rick (second comment down in the blog post mentioned), here's the MSDN article on httpOnlyCookies.

Bottom line is that you just add the following section in your system.web section in your web.config:

<httpCookies domain="" httpOnlyCookies="true|false" requireSSL="true|false" />

as zsolt mentioned, some regex engines support recursion -- of course, these are typically the ones that use a backtracking algorithm so it won't be particularly efficient. example: /(?>[^{}]*){(?>[^{}]*)(?R)*(?>[^{}]*)}/sm

If ID(and all coulmns) is needed from mytable

SELECT

        AND A.age < B.age

You can bind the DOMSubtreeModified event. I add an example here:

HTML

<div id="mutable" style="width:50px;height:50px;">sjdfhksfh<div>
<div>
  <button id="changeClass">Change Class</button>
</div>

JavaScript

$(document).ready(function() {
  $('#changeClass').click(function() {
    $('#mutable').addClass("red");
  });

  $('#mutable').bind('DOMSubtreeModified', function(e) {
      alert('class changed');
  });
});

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

In a project with multiple targets I had the same issue after changing the Scheme and App name and tried to update pods. The issue was caused because of multiple entries in Build Phases -> Link Binary with Libraries where both the previous .a library and the current one was listed, while the previous one was not existing anymore. Removing the library from there cleared the problem.

You can use the code below to install application from command line

adb install example.apk

this apk is installed in the internal memory of current opened emulator.

adb install -s example.apk

this apk is installed in the sd-card of current opened emulator.

You can also install an apk to specific device in connected device list to the adb.

adb -s emulator-5554 install myapp.apk

Refer also to adb help for other options.

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml

Angular now has a type of iterate Object for exactly this scenario, called a Set. It fit my needs when I found this question searching. You create the set, "add" to it like you'd "push" to an array, and drop it in an ngFor just like an array. No pipes or anything.

this.myObjList = new Set();

...

this.myObjList.add(obj);

...

<ul>
   <li *ngFor="let object of myObjList">
     {{object}}
   </li>
</ul>

Try this query (replace t.eventsDate with e.eventsDate):

SELECT e FROM Events e WHERE e.eventsDate BETWEEN :startDate AND :endDate

The Set statement is only used for object variables (like Range, Cell or Worksheet in Excel), while the simple equal sign '=' is used for elementary datatypes like Integer. You can find a good explanation for when to use set here.

The other problem is, that your variable g1val isn't actually declared as Integer, but has the type Variant. This is because the Dim statement doesn't work the way you would expect it, here (see example below). The variable has to be followed by its type right away, otherwise its type will default to Variant. You can only shorten your Dim statement this way:

Dim intColumn As Integer, intRow As Integer  'This creates two integers

For this reason, you will see the "Empty" instead of the expected "0" in the Watches window.

Try this example to understand the difference:

Sub Dimming()

  Dim thisBecomesVariant, thisIsAnInteger As Integer
  Dim integerOne As Integer, integerTwo As Integer

  MsgBox TypeName(thisBecomesVariant)  'Will display "Empty"
  MsgBox TypeName(thisIsAnInteger )  'Will display "Integer"
  MsgBox TypeName(integerOne )  'Will display "Integer"
  MsgBox TypeName(integerTwo )  'Will display "Integer"

  'By assigning an Integer value to a Variant it becomes Integer, too
  thisBecomesVariant = 0
  MsgBox TypeName(thisBecomesVariant)  'Will display "Integer"

End Sub

Two further notices on your code:

First remark: Instead of writing

'If g1val is bigger than the value in the current cell
If g1val > Cells(33, i).Value Then
  g1val = g1val   'Don't change g1val
Else
  g1val = Cells(33, i).Value  'Otherwise set g1val to the cell's value
End If

you could simply write

'If g1val is smaller or equal than the value in the current cell
If g1val <= Cells(33, i).Value Then
  g1val = Cells(33, i).Value  'Set g1val to the cell's value 
End If

Since you don't want to change g1val in the other case.

Second remark: I encourage you to use Option Explicit when programming, to prevent typos in your program. You will then have to declare all variables and the compiler will give you a warning if a variable is unknown.

Yes, this is confusing...

According to this blog post, it looks like this is an omission from WPF.

To make it work you need to use a style:

    <Border Name="ClearButtonBorder" Grid.Column="1" CornerRadius="0,3,3,0">
        <Border.Style>
            <Style>
                <Setter Property="Border.Background" Value="Blue"/>
                <Style.Triggers>
                    <Trigger Property="Border.IsMouseOver" Value="True">
                        <Setter Property="Border.Background" Value="Green" />
                    </Trigger>
                </Style.Triggers>
            </Style>
        </Border.Style>
        <TextBlock HorizontalAlignment="Center" VerticalAlignment="Center" Text="X" />
    </Border>

I guess this problem isn't that common as most people tend to factor out this sort of thing into a style, so it can be used on multiple controls.

You should learn the raise statement of python for that. It should be kept inside the try block. Example -

try:
    raise TypeError            #remove TypeError by any other error if you want
except TypeError:
    print('TypeError raised')

You can use std::map::at member function, it returns a reference to the mapped value of the element identified with key k.

std::map<char,int> mymap = {
                               { 'a', 0 },
                               { 'b', 0 },
                           };

  mymap.at('a') = 10;
  mymap.at('b') = 20;

Actually the answer by ƒernando Valle doesn't seem to be correct. Then again, your question is overly vague because you fail to mention what is wrong or isn't working.

Looking at your code I am assuming the Notification simply isn't showing.

Your notification is not showing, because you didn't provide an icon. Even though the SDK documentation doesn't mention it being required, it is in fact very much so and your Notification will not show without one.

addAction is only available since 4.1. Prior to that you would use the PendingIntent to launch an Activity. You seem to specify a PendingIntent, so your problem lies elsewhere. Logically, one must conclude it's the missing icon.

I found the same problem and i tried all the solution mentioned above and in github. Some works only in local repository, when i push my PR in remote repositories with travic-CI or Pipelines give me the same error back. Finally i fixed it by using the npm command below.

npm audit fix --force

var str = "How are you doing today?";

var res = str.split(" ");

Here the variable "res" is kind of array.

You can also take this explicity by declaring it as

var res[]= str.split(" ");

Now you can access the individual words of the array. Suppose you want to access the third element of the array you can use it by indexing array elements.

var FirstElement= res[0];

Now the variable FirstElement contains the value 'How'

This will select the last two iems of a list:

li:nth-last-child(-n+2) {color:red;}

<ul>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>
  <li>fred</li>

  <li>fred</li>

To delete a specific line of a file by its line number:

Replace variables filename and line_to_delete with the name of your file and the line number you want to delete.

filename = 'foo.txt'
line_to_delete = 3
initial_line = 1
file_lines = {}

with open(filename) as f:
    content = f.readlines() 

for line in content:
    file_lines[initial_line] = line.strip()
    initial_line += 1

f = open(filename, "w")
for line_number, line_content in file_lines.items():
    if line_number != line_to_delete:
        f.write('{}\n'.format(line_content))

f.close()
print('Deleted line: {}'.format(line_to_delete))

Example output:

Deleted line: 3

The following can be used to get the date:

function date_date() {
var date = new Date();
var year = date.getYear();
var month = date.getMonth() + 1;  if(month.toString().length==1){var month = 
'0'+month;}
var day = date.getDate(); if(day.toString().length==1){var day = '0'+day;}
var hour = date.getHours(); if(hour.toString().length==1){var hour = '0'+hour;}
var minu = date.getMinutes(); if(minu.toString().length==1){var minu = '0'+minu;}
var seco = date.getSeconds(); if(seco.toString().length==1){var seco = '0'+seco;}
var date = year+'·'+month+'·'+day+'·'+hour+'·'+minu+'·'+seco;
Logger.log(date);
}

I have an Xml File books.xml

<ParameterDBConfig>
    <ID Definition="1" />
</ParameterDBConfig>

Program:

XmlDocument doc = new XmlDocument();
doc.Load("D:/siva/books.xml");
XmlNodeList elemList = doc.GetElementsByTagName("ID");     
for (int i = 0; i < elemList.Count; i++)     
{
    string attrVal = elemList[i].Attributes["Definition"].Value;
}

Now, attrVal has the value of ID.

If none of the above solution work, you should check the READ ONLY property of the Project folder, if it is Read-Only, the compiler will not be able to overwrite the resources, R.java and other dex APK etc files and hence this will occur.. This happened to me and I fixed after a long struggle.. Happy Programming.

It can happen that using redis-cli, you connect to your remote redis-server, and then the command:

KEYS *

is not showing anything, or better, it shows:
(empty list or set)

If you are absolutely sure that the Redis server you use is the one you have the data, then maybe your redis-cli is not connecting to the Redis correct database instance.

As it is mentioned in the Redis docs, new connections connect as default to the db 0.

In my case KEYS command was not retrieving results because my database was 1. In order to select the db you want, use SELECT.
The db is identified by an integer.

SELECT 1
KEYS *

I post this info because none of the previous answers was solving my issue.

The solution is:

NameVirtualHost *:80
Listen 80

(...)

<VirtualHost *:80>
    ServerName host1
    DocumentRoot /someDir
</VirtualHost>

<VirtualHost *:80>
    ServerName host2
    DocumentRoot /someOtherDir
</VirtualHost>

<VirtualHost *:80>
    ServerName aaaa.com
    DocumentRoot /defaultDir
</VirtualHost>

In my case, to work, I created a VirtualHost (n.e. VirtualHost per CNAME) called aaaa.com since I have different files for different VirtualHosts and knowing that Apache reads them in alphabetical order.

I am not sure if the above CSV generation code is so great as it appears to skip th cells and also did not appear to allow for commas in the value. So here is my CSV generation code that might be useful.

It does assume you have the $table variable which is a jQuery object (eg. var $table = $('#yourtable');)

$rows = $table.find('tr');

var csvData = "";

for(var i=0;i<$rows.length;i++){
                var $cells = $($rows[i]).children('th,td'); //header or content cells

                for(var y=0;y<$cells.length;y++){
                    if(y>0){
                      csvData += ",";
                    }
                    var txt = ($($cells[y]).text()).toString().trim();
                    if(txt.indexOf(',')>=0 || txt.indexOf('\"')>=0 || txt.indexOf('\n')>=0){
                        txt = "\"" + txt.replace(/\"/g, "\"\"") + "\"";
                    }
                    csvData += txt;
                }
                csvData += '\n';
 }

@Alan's answer will do what you're looking for, but this solution fails when you use the responsive capabilities of Bootstrap. In your case, you're using the xs sizes so you won't notice, but if you used anything else (e.g. col-sm, col-md, etc), you'd understand.

Another approach is to play with margins and padding. See the updated fiddle: http://jsfiddle.net/jz8j247x/1/

.left-side {
  background-color: blue;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.something {
  height: 100%;
  background-color: red;
  padding-bottom: 1000px;
  margin-bottom: -1000px;
  height: 100%;
}
.row {
  background-color: green;
  overflow: hidden;
}

The KB article linked in Joe's post is great for determining which service packs have been installed for any version. Along those same lines, this KB article maps version numbers to specific hotfixes and cumulative updates, but it only applies to SQL05 SP2 and up.

I encountered this padding error when i would manually edit the encrypted strings in the file (using notepad) because i wanted to test how decryption function will behave if my encrypted content was altered manually.

The solution for me was to place a

        try
            decryption stuff....
        catch
             inform decryption will not be carried out.
        end try

Like i said my padding error was because i was manually typing over the decrypted text using notepad. May be my answer may guide you to your solution.

Following issue 8959, a good start would be:

docker ps -a -q --filter="name=<containerName>"

Since name refers to the container and not the image name, you would need to use the more recent Docker 1.9 filter ancestor, mentioned in koekiebox's answer.

docker ps -a -q  --filter ancestor=<image-name>

As commented below by kiril, to remove those containers:

stop returns the containers as well.

So chaining stop and rm will do the job:

docker rm $(docker stop $(docker ps -a -q --filter ancestor=<image-name> --format="{{.ID}}"))

Author Note

This answer is out of date. Fig not longer exists and has been replaced by Docker compose. Accepted answers cannot be deleted ....

Docker Compose supports the building of project hierachy. So it's now easy to support a Dockerfile in each sub directory.

+-- docker-compose.yml
+-- project1
¦   +-- Dockerfile
+-- project2
    +-- Dockerfile

Original answer

I just create a directory containing a Dockerfile for each component. Example:

• Setting up a docker / fig Mesos environment

When building the containers just give the directory name and Docker will select the correct Dockerfile.

This query can also be used.

DECLARE @SelectedDate DATE =  GETDATE()

SELECT DATEADD(DAY, - DAY(@SelectedDate), DATEADD(MONTH, 1 , @SelectedDate)) EndOfMonth

I was working also on web scraping project and same issue found, below code applied and it worked nicely. If you are not aware about TLS versions then you can apply all below otherwise you can apply specific.

ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11;

I like the following because it puts the results into a vector, supports a string as a delim and gives control over keeping empty values. But, it doesn't look as good then.

#include <ostream>
#include <string>
#include <vector>
#include <algorithm>
#include <iterator>
using namespace std;

vector<string> split(const string& s, const string& delim, const bool keep_empty = true) {
    vector<string> result;
    if (delim.empty()) {
        result.push_back(s);
        return result;
    }
    string::const_iterator substart = s.begin(), subend;
    while (true) {
        subend = search(substart, s.end(), delim.begin(), delim.end());
        string temp(substart, subend);
        if (keep_empty || !temp.empty()) {
            result.push_back(temp);
        }
        if (subend == s.end()) {
            break;
        }
        substart = subend + delim.size();
    }
    return result;
}

int main() {
    const vector<string> words = split("So close no matter how far", " ");
    copy(words.begin(), words.end(), ostream_iterator<string>(cout, "\n"));
}

Of course, Boost has a split() that works partially like that. And, if by 'white-space', you really do mean any type of white-space, using Boost's split with is_any_of() works great.

The simplest solution would be a correlated sub select:

select
    A.*
from
    table_A A
where
    A.id in (
        select B.id from table_B B where B.tag = 'chair'
)

Alternatively you could join the tables and filter the rows you want:

select
    A.*
from
    table_A A
inner join table_B B
    on A.id = B.id
where
    B.tag = 'chair'

You should profile both and see which is faster on your dataset.

I did the following to get my Mac to see the devices again:

• Run android update adb
• Run adb kill-server
• Run adb start-server

At this point, calling adb devices started returning devices again. Now run or debug your project to test it on your device.

In addition to the accepted answer from 2009. If you can can target modern browsers, one can make use of the Object.defineProperty.

The Object.defineProperty() method defines a new property directly on an object, or modifies an existing property on an object, and returns the object. Source: Mozilla

var Foo = (function () {
    function Foo() {
        this._bar = false;
    }
    Object.defineProperty(Foo.prototype, "bar", {
        get: function () {
            return this._bar;
        },
        set: function (theBar) {
            this._bar = theBar;
        },
        enumerable: true,
        configurable: true
    });
    Foo.prototype.toTest = function () {
        alert("my value is " + this.bar);
    };
    return Foo;
}());

// test instance
var test = new Foo();
test.bar = true;
test.toTest();

To see a desktop and mobile compatibility list, see Mozilla's Browser Compatibility list. Yes, IE9+ supports it as well as Safari mobile.

Normal text editors are nano, or vi.

For example:

root@user:# nano galfit.feedme

or

root@user:# vi galfit.feedme

I'd add, that you can also use this to call multiple emits or methods or both together by separating with ; semicolon

  @click="method1(); $emit('emit1'); $emit('emit2');"

Wouldn't a normal foreach basically yield the same result as a mysql_fetch_assoc in your case?

when using foreach on that array, you would get an array containing those three keys: 'id','firstname' and 'lastname'.

That should be the same as mysql_fetch_assoc would give (in a loop) for each row.

2020 Update

This is now possible:

On Android 11, you can do

view.setWindowInsetsAnimationCallback(object : WindowInsetsAnimation.Callback {
    override fun onEnd(animation: WindowInsetsAnimation) {
        super.onEnd(animation)
        val showingKeyboard = view.rootWindowInsets.isVisible(WindowInsets.Type.ime())
        // now use the boolean for something
    }
})

You can also listen to the animation of showing/hiding the keyboard and do a corresponding transition.

I recommend reading Android 11 preview and the corresponding documentation

Before Android 11

However, this work has not been made available in a Compat version, so you need to resort to hacks.

You can get the window insets and if the bottom insets are bigger than some value you find to be reasonably good (by experimentation), you can consider that to be showing the keyboard. This is not great and can fail in some cases, but there is no framework support for that.

This is a good answer on this exact question https://stackoverflow.com/a/36259261/372076. Alternatively, here's a page giving some different approaches to achieve this pre Android 11:

https://developer.salesforce.com/docs/atlas.en-us.noversion.service_sdk_android.meta/service_sdk_android/android_detecting_keyboard.htm

Note

This solution will not work for soft keyboards and onConfigurationChanged will not be called for soft (virtual) keyboards.

You've got to handle configuration changes yourself.

http://developer.android.com/guide/topics/resources/runtime-changes.html#HandlingTheChange

Sample:

// from the link above
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    
    // Checks whether a hardware keyboard is available
    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

Then just change the visibility of some views, update a field, and change your layout file.

Problem solved, I've not added the index.html. Which is point out in the web.xml

Note: a project may have more than one web.xml file.

if there are another web.xml in

src/main/webapp/WEB-INF

Then you might need to add another index (this time index.jsp) to

src/main/webapp/WEB-INF/pages/

You need to define the size of file...

header('Content-Length: ' . filesize($file));

And this line is wrong:

header("Content-Disposition:inline;filename='$filename");

You messed up quotas.

It is just equally spaced hues around the color wheel, starting from 15:

gg_color_hue <- function(n) {
  hues = seq(15, 375, length = n + 1)
  hcl(h = hues, l = 65, c = 100)[1:n]
}

For example:

n = 4
cols = gg_color_hue(n)

dev.new(width = 4, height = 4)
plot(1:n, pch = 16, cex = 2, col = cols)

Try Ehcache? It allows you to plug in your own caching expiry algorithms so you could control your peek functionality.

You can serialize to disk, database, across a cluster etc...

Many people have answered the mechanical details already, but it's worth noting: This is a poor design choice, by Java.

Java's asList method is documented as "Returns a fixed-size list...". If you take its result and call (say) the .add method, it throws an UnsupportedOperationException. This is unintuitive behavior! If a method says it returns a List, the standard expectation is that it returns an object which supports the methods of interface List. A developer shouldn't have to memorize which of the umpteen util.List methods create Lists that don't actually support all the List methods.

If they had named the method asImmutableList, it would make sense. Or if they just had the method return an actual List (and copy the backing array), it would make sense. They decided to favor both runtime-performance and short names, at the expense of violating both the Principle of Least Surprise and the good-O.O. practice of avoiding UnsupportedOperationExceptions.

(Also, the designers might have made a interface ImmutableList, to avoid a plethora of UnsupportedOperationExceptions.)

Form the Inheritance concept, If some perticular method is not available in the current class it will search for that method in super classes. If available it executes.

It executes AbstractList<E> class add() method which throws UnsupportedOperationException.

When you are converting from an Array to a Collection Obejct. i.e., array-based to collection-based API then it is going to provide you fixed-size collection object, because Array's behaviour is of Fixed size.

java.util.Arrays.asList( T... a )

Souce samples for conformation.

public class Arrays {
    public static <T> List<T> asList(T... a) {
        return new java.util.Arrays.ArrayList.ArrayList<>(a); // Arrays Inner Class ArrayList
    }
    //...
    private static class ArrayList<E> extends AbstractList<E> implements RandomAccess, java.io.Serializable {
        //...
    }
}
public abstract class AbstractList<E> extends AbstractCollection<E> implements List<E> {
    public void add(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E set(int index, E element) {
        throw new UnsupportedOperationException();
    }
    public E remove(int index) {
        throw new UnsupportedOperationException();
    }

    public Iterator<E> iterator() {
        return new Itr();
    }
    private class Itr implements Iterator<E> {
        //...
    }

    public ListIterator<E> listIterator() {
        return listIterator(0);
    }
    private class ListItr extends Itr implements ListIterator<E> {
        //...
    }
}

Form the above Source you may observe that java.util.Arrays.ArrayList class doesn't @Override add(index, element), set(index, element), remove(index). So, From inheritance it executes super AbstractList<E> class add() function which throws UnsupportedOperationException.

As AbstractList<E> is an abstract class it provides the implementation to iterator() and listIterator(). So, that we can iterate over the list object.

List<String> list_of_Arrays = Arrays.asList(new String[] { "a", "b" ,"c"});

try {
    list_of_Arrays.add("Yashwanth.M");
} catch(java.lang.UnsupportedOperationException e) {
    System.out.println("List Interface executes AbstractList add() fucntion which throws UnsupportedOperationException.");
}
System.out.println("Arrays ? List : " + list_of_Arrays);

Iterator<String> iterator = list_of_Arrays.iterator();
while (iterator.hasNext()) System.out.println("Iteration : " + iterator.next() );

ListIterator<String> listIterator = list_of_Arrays.listIterator();
while (listIterator.hasNext())    System.out.println("Forward  iteration : " + listIterator.next() );
while(listIterator.hasPrevious()) System.out.println("Backward iteration : " + listIterator.previous());

You can even create Fixed-Size array form Collections class Collections.unmodifiableList(list);

Sample Source:

public class Collections {
    public static <T> List<T> unmodifiableList(List<? extends T> list) {
        return (list instanceof RandomAccess ?
                new UnmodifiableRandomAccessList<>(list) :
                new UnmodifiableList<>(list));
    }
}

A Collection — sometimes called a container — is simply an object that groups multiple elements into a single unit. Collections are used to store, retrieve, manipulate, and communicate aggregate data.

Constraints are part of a database schema definition.

A constraint is usually associated with a table and is created with a CREATE CONSTRAINT or CREATE ASSERTION SQL statement.

They define certain properties that data in a database must comply with. They can apply to a column, a whole table, more than one table or an entire schema. A reliable database system ensures that constraints hold at all times (except possibly inside a transaction, for so called deferred constraints).

Common kinds of constraints are:

• not null - each value in a column must not be NULL
• unique - value(s) in specified column(s) must be unique for each row in a table
• primary key - value(s) in specified column(s) must be unique for each row in a table and not be NULL; normally each table in a database should have a primary key - it is used to identify individual records
• foreign key - value(s) in specified column(s) must reference an existing record in another table (via it's primary key or some other unique constraint)
• check - an expression is specified, which must evaluate to true for constraint to be satisfied

The easiest way to do this is to format a cell the way you want it, then use the "cell format ..." contextual menu to get to the fill and format colours, use the "more colors ..." button to get to the hexagon colour selector, select the custom tab.

The RGB colours are as in the table at the bottom of the pane. If you prefer HSL values change the color model from RGB to HSL. I have used this to change the saturation on my bad cells. A higher luminosity gives a worse results and the shade of all the cells is the same just the deepness of the colour is modified.

Perhaps you could try using the DateTime.FromOADate method to convert between Excel and .net.

To quote the help page (try ?integer), bolded portion mine:

Integer vectors exist so that data can be passed to C or Fortran code which expects them, and so that (small) integer data can be represented exactly and compactly.

Note that current implementations of R use 32-bit integers for integer vectors, so the range of representable integers is restricted to about +/-2*10^9: doubles can hold much larger integers exactly.

Like the help page says, R's integers are signed 32-bit numbers so can hold between -2147483648 and +2147483647 and take up 4 bytes.

R's numeric is identical to an 64-bit double conforming to the IEEE 754 standard. R has no single precision data type. (source: help pages of numeric and double). A double can store all integers between -2^53 and 2^53 exactly without losing precision.

We can see the data type sizes, including the overhead of a vector (source):

> object.size(1:1000)
4040 bytes
> object.size(as.numeric(1:1000))
8040 bytes

There are times that using OPTION(RECOMPILE) makes sense. In my experience the only time this is a viable option is when you are using dynamic SQL. Before you explore whether this makes sense in your situation I would recommend rebuilding your statistics. This can be done by running the following:

EXEC sp_updatestats

And then recreating your execution plan. This will ensure that when your execution plan is created it will be using the latest information.

Adding OPTION(RECOMPILE) rebuilds the execution plan every time that your query executes. I have never heard that described as creates a new lookup strategy but maybe we are just using different terms for the same thing.

When a stored procedure is created (I suspect you are calling ad-hoc sql from .NET but if you are using a parameterized query then this ends up being a stored proc call) SQL Server attempts to determine the most effective execution plan for this query based on the data in your database and the parameters passed in (parameter sniffing), and then caches this plan. This means that if you create the query where there are 10 records in your database and then execute it when there are 100,000,000 records the cached execution plan may no longer be the most effective.

In summary - I don't see any reason that OPTION(RECOMPILE) would be a benefit here. I suspect you just need to update your statistics and your execution plan. Rebuilding statistics can be an essential part of DBA work depending on your situation. If you are still having problems after updating your stats, I would suggest posting both execution plans.

And to answer your question - yes, I would say it is highly unusual for your best option to be recompiling the execution plan every time you execute the query.

sometimes, you need to limit the string to the last complete word ie: you don't want the last word to be broken instead you stop with the second last word.

eg: we need to limit "This is my String" to 6 chars but instead of 'This i..." we want it to be 'This..." ie we will skip that broken letters in the last word.

phew, am bad at explaining, here is the code.

class Fun {

    public function limit_text($text, $len) {
        if (strlen($text) < $len) {
            return $text;
        }
        $text_words = explode(' ', $text);
        $out = null;


        foreach ($text_words as $word) {
            if ((strlen($word) > $len) && $out == null) {

                return substr($word, 0, $len) . "...";
            }
            if ((strlen($out) + strlen($word)) > $len) {
                return $out . "...";
            }
            $out.=" " . $word;
        }
        return $out;
    }

}

I use this:

@var.respond_to?(:keys)

It works for Hash and ActiveSupport::HashWithIndifferentAccess.

Just had the same problem adding menu items to Wordpress. I am using Wordpress 4.9.9 on Ubuntu 18.04, PHP 7.0. I simply uncommented the following line and increased it to 1500 in /etc/php/7.0/apache2/php.ini

This worked for me and I think this is the most basic solution which involves the least setup possible:

1. With your PC and other device connected to the same network , open cmd from your PC which you plan to set up as a server, and hit ipconfig to get your ip address. Note this ip address. It should be something like "192.168.1.2" which is the value to the right of IPv4 Address field as shown in below format:

Wireless LAN adapter Wi-Fi:

Connection-specific DNS Suffix . :
Link-local IPv6 Address . . . . . : ffff::ffff:ffff:ffff:ffad%14
IPv4 Address. . . . . . . . . . . : 192.168.1.2
Subnet Mask . . . . . . . . . . . : 255.255.255.0

2. Start your node server like this : npm start <IP obtained in step 1:3000> e.g. npm start 192.168.1.2:3000
3. Open browser of your other device and hit the url: <your_ip:3000> i.e. 192.168.1.2:3000 and you will see your website.

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

String has a constructor that takes byte[] and charsetname as parameters :)

Just write <a href="#"></a>.

If that's what you want, you don't need a server-side control.

I had the same issue and the issue was some js files were not included in the bundling of that specific page. Try including those file and problem might be fixed. I did this:

The accepted answer is incorrect.

createNativeQuery will always return a Query:

public Query createNativeQuery(String sqlString, Class resultClass);

Calling getResultList on a Query returns List:

List getResultList()

When assigning (or casting) to List<MyEntity>, an unchecked assignment warning is produced.

Whereas, createQuery will return a TypedQuery:

public <T> TypedQuery<T> createQuery(String qlString, Class<T> resultClass);

Calling getResultList on a TypedQuery returns List<X>.

List<X> getResultList();

This is properly typed and will not give a warning.

With createNativeQuery, using ObjectMapper seems to be the only way to get rid of the warning. Personally, I choose to suppress the warning, as I see this as a deficiency in the library and not something I should have to worry about.

There is a third recovery mode not mentioned above. The recovery mode ultimately determines how large the LDF files become and how ofter they are written to. In cases where you are going to be doing any type of bulk inserts, you should set the DB to be in "BULK/LOGGED". This makes bulk inserts move speedily along and can be changed on the fly.

To do so,

USE master ;
ALTER DATABASE model SET RECOVERY BULK_LOGGED ;

To change it back:

USE master ;
ALTER DATABASE model SET RECOVERY FULL ;

In the spirit of adding to the conversation about why someone would not want an LDF, I add this: We do multi-dimensional modelling. Essentially we use the DB as a large store of variables that are processed in bulk using external programs. We do not EVER require rollbacks. If we could get a performance boost by turning of ALL logging, we'd take it in a heart beat.

Given that today (was not available when this question was made) lots of people use Jupyter Notebook as python console, there is an extremely easy way to save the plots as .png, just call the matplotlib's pylab class from Jupyter Notebook, plot the figure 'inline' jupyter cells, and then drag that figure/image to a local directory. Don't forget %matplotlib inline in the first line!

Here's an example program that will send myfile.mp3 by streaming it from disk (that is, it doesn't read the whole file into memory before sending the file). The server listens on port 2000.

[Update] As mentioned by @Aftershock in the comments, util.pump is gone and was replaced with a method on the Stream prototype called pipe; the code below reflects this.

var http = require('http'),
    fileSystem = require('fs'),
    path = require('path');

http.createServer(function(request, response) {
    var filePath = path.join(__dirname, 'myfile.mp3');
    var stat = fileSystem.statSync(filePath);

    response.writeHead(200, {
        'Content-Type': 'audio/mpeg',
        'Content-Length': stat.size
    });

    var readStream = fileSystem.createReadStream(filePath);
    // We replaced all the event handlers with a simple call to readStream.pipe()
    readStream.pipe(response);

I saw a lot of answers here but I didn't try any of them. I've just created the filter as in the following code.

import org.springframework.context.annotation.Configuration;
import javax.servlet.*;
import javax.servlet.annotation.WebFilter;
import java.io.IOException;

@WebFilter(urlPatterns = "/Admin")
@Configuration
public class AdminFilter implements Filter{
    @Override
    public void init(FilterConfig filterConfig) throws ServletException {

    }

    @Override
    public void doFilter(ServletRequest servletRequest, ServletResponse  servletResponse, FilterChain filterChain) throws IOException, ServletException      {
    System.out.println("happened");

    }

    @Override
    public void destroy() {

    }
}

And leaved the remaining Spring Boot application as it was.

You can convert a set into an ArrayList, where you can sort the ArrayList using Collections.sort(List).

Here is the code:

keySet = (Set) map.keySet();
ArrayList list = new ArrayList(keySet);     
Collections.sort(list);

Have a think about wrapping the videos inside something which you can make flexible via bootsrap.

The bootstrap is not a magic tool, its just a layout engine. You almost have it in your example.

Just use the grid provided by bootstrap and remove strict sizing's on the iframe. Use the bootstrap class guides for the grid..

For example:

<iframe class="col-lg-2 col-md-6 col-sm-12 col-xs-12">

You will see how the class of the iframe will change then given your resolution.

Based on what I've read and my experience with Django so far, auto_now_add is buggy. I agree with jthanism --- override the normal save method it's clean and you know what's hapenning. Now, to make it dry, create an abstract model called TimeStamped:

from django.utils import timezone

class TimeStamped(models.Model):
    creation_date = models.DateTimeField(editable=False)
    last_modified = models.DateTimeField(editable=False)

    def save(self, *args, **kwargs):
        if not self.creation_date:
            self.creation_date = timezone.now()

        self.last_modified = timezone.now()
        return super(TimeStamped, self).save(*args, **kwargs)

    class Meta:
        abstract = True

And then, when you want a model that has this time-stampy behavior, just subclass:

MyNewTimeStampyModel(TimeStamped):
    field1 = ...

If you want the fields to show up in admin, then just remove the editable=False option

Find your binaries file where it is saved. get the path in terminal mine is

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin

then find your local user data path, it is in mostly

C:\usr\local\pgsql\data

now all we have to hit the following command in the binary terminal path:

C:\Users\LENOVO\Documents\postgresql-9.5.21-1-windows-x64-binaries (1)\pgsql\bin>pg_ctl -D "C:\usr\local\pgsql\data" start

done!

The main reason is that Proguard would remove Log calls from production. Because by logging or printing StackTrace, it is possible to see them (information inside stack trace or Log) inside the Android phone by for example Logcat Reader application. So that it is a bad practice for security. Also, we do not access them during production, it would better to get removed from production. As ProGuard remove all Log calls not stackTrace, so it is better to use Log in catch blocks and let them removed from Production by Proguard.

public int[] getDigitsOfANumber(int number) {
    String numStr = String.valueOf(number);
    int retArr[] = new int[numStr.length()];

        char c = numStr.charAt(i);
        int digit = c;
        int zero = (char) '0';
        retArr[i] = digit - zero;

    }
    return retArr;

With ireport 4.7.1, after setting jdkhome in etc/ireport.conf, ireport.exe doesn't start. No splash, no window.

When I launch ireport_w.exe in a cmd, I get this message:

Error occurred during initialization of VM

Could not reserve enough space for object heap

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

Solution: In file etc/ireport.conf, on the line starting with default_options, I have reduced the value of -J-XX:MaxPermSize to 256m instead of 512m

default_options="--branding ireport -J-Xms256m -J-Xmx512m
    -J-Dorg.netbeans.ProxyClassLoader.level=1000 -J-XX:MaxPermSize=256m"

You can do something like this :

dictionary = {'ab': {object}, 'cd':{object}, 'ef':{object}}
var keys = Object.keys(dictionary);

for(var i = 0; i < keys.length;i++){
   //keys[i] for key
   //dictionary[keys[i]] for the value
}

I may have to reload the image source several times. I found a solution with Lodash that works well for me:

$("#myimg").attr('src', _.split($("#myimg").attr('src'), '?', 1)[0] + '?t=' + _.now());

An existing timestamp will be truncated and replaced with a new one.

We can use signals for the same. I think the below example will be useful for you. It is very simple compared to threads.

import signal

def timeout(signum, frame):
    raise myException

#this is an infinite loop, never ending under normal circumstances
def main():
    print 'Starting Main ',
    while 1:
        print 'in main ',

#SIGALRM is only usable on a unix platform
signal.signal(signal.SIGALRM, timeout)

#change 5 to however many seconds you need
signal.alarm(5)

try:
    main()
except myException:
    print "whoops"

Have created a simple dictionary in JS here:

function JSdict() {
    this.Keys = [];
    this.Values = [];
}

// Check if dictionary extensions aren't implemented yet.
// Returns value of a key
if (!JSdict.prototype.getVal) {
    JSdict.prototype.getVal = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        for (var i = 0; i < this.Keys.length; i++) {
            if (this.Keys[i] == key) {
                return this.Values[i];
            }
        }
        return "Key not found!";
    }
}


// Check if dictionary extensions aren't implemented yet.
// Updates value of a key
if (!JSdict.prototype.update) {
    JSdict.prototype.update = function (key, val) {
        if (key == null || val == null) {
            return "Key or Value cannot be null";
        }
        // Verify dict integrity before each operation
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Values[i] = val;
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}



// Check if dictionary extensions aren't implemented yet.
// Adds a unique key value pair
if (!JSdict.prototype.add) {
    JSdict.prototype.add = function (key, val) {
        // Allow only strings or numbers as keys
        if (typeof (key) == "number" || typeof (key) == "string") {
            if (key == null || val == null) {
                return "Key or Value cannot be null";
            }
            if (keysLength != valsLength) {
                return "Dictionary inconsistent. Keys length don't match values!";
            }
            var keysLength = this.Keys.length;
            var valsLength = this.Values.length;
            for (var i = 0; i < keysLength; i++) {
                if (this.Keys[i] == key) {
                    return "Duplicate keys not allowed!";
                }
            }
            this.Keys.push(key);
            this.Values.push(val);
        }
        else {
            return "Only number or string can be key!";
        }
    }
}

// Check if dictionary extensions aren't implemented yet.
// Removes a key value pair
if (!JSdict.prototype.remove) {
    JSdict.prototype.remove = function (key) {
        if (key == null) {
            return "Key cannot be null";
        }
        if (keysLength != valsLength) {
            return "Dictionary inconsistent. Keys length don't match values!";
        }
        var keysLength = this.Keys.length;
        var valsLength = this.Values.length;
        var flag = false;
        for (var i = 0; i < keysLength; i++) {
            if (this.Keys[i] == key) {
                this.Keys.shift(key);
                this.Values.shift(this.Values[i]);
                flag = true;
                break;
            }
        }
        if (!flag) {
            return "Key does not exist";
        }
    }
}

The above implementation can now be used to simulate a dictionary as:

var dict = new JSdict();

dict.add(1, "one")

dict.add(1, "one more")
"Duplicate keys not allowed!"

dict.getVal(1)
"one"

dict.update(1, "onne")

dict.getVal(1)
"onne"

dict.remove(1)

dict.getVal(1)
"Key not found!"

This is just a basic simulation. It can be further optimized by implementing a better running time algorithm to work in atleast O(nlogn) time complexity or even less. Like merge/quick sort on arrays and then some B-search for lookups. I Didn't give a try or searched about mapping a hash function in JS.

Also, Key and Value for the JSdict obj can be turned into private variables to be sneaky.

Hope this helps!

EDIT >> After implementing the above, I personally used the JS objects as associative arrays that are available out-of-the-box.

However, I would like to make a special mention about two methods that actually proved helpful to make it a convenient hashtable experience.

Viz: dict.hasOwnProperty(key) and delete dict[key]

Read this post as a good resource on this implementation/usage. Dynamically creating keys in JavaScript associative array

THanks!

"ModelState.IsValid" tells you that the model is consumed by the view (i.e. PaymentAdviceEntity) is satisfy all types of validation or not specified in the model properties by DataAnotation.

In this code the view does not bind any model properties. So if you put any DataAnotations or validation in model (i.e. PaymentAdviceEntity). then the validations are not satisfy. say if any properties in model is Name which makes required in model.Then the value of the property remains blank after post.So the model is not valid (i.e. ModelState.IsValid returns false). You need to remove the model level validations.

fmt.SprintF function returns a string and you can format the string the very same way you would have with fmt.PrintF

select sum(s) from (select count(Col_name) as s from Tab_name group by Col_name having count(*)>1)c

Alternative way (but it's not python style. It's JS style)

{{ files and 'Update' or 'Continue' }}

To remove all cookies you could write:

foreach ($_COOKIE as $key => $value) {
    unset($value);
    setcookie($key, '', time() - 3600);
}

All the solutions here failed to work on my VS2013, however I put the #define _CRT_SECURE_NO_WARNINGS in the stdafx.h just before the #pragma once and all warnings were suppressed. Note: I only code for prototyping purposes to support my research so please make sure you understand the implications of this method when writing your code.

Hope this helps

No my friend its very simple, try using this:

AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
alertDialog.setTitle("Alert Dialog");
alertDialog.setMessage("Welcome to dear user.");
alertDialog.setIcon(R.drawable.welcome);

alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
    }
});

alertDialog.show();

This tutorial shows how you can create custom dialog using xml and then show them as an alert dialog.

float is the closest equivalent.

SqlDbType Enumeration

For Lat/Long as OP mentioned.

A metre is 1/40,000,000 of the latitude, 1 second is around 30 metres. Float/double give you 15 significant figures. With some quick and dodgy mental arithmetic... the rounding/approximation errors would be the about the length of this fill stop -> "."

Along with the latest software (latest Eclipse and Java) and more RAM, you may need to

• Remove the unwanted plugins (not all need Mylyn and J2EE version of Eclipse)
• unwanted validators
• disable spell check
• close unused tabs in Java editor (yes it helps reducing Eclipse burden)
• close unused projects
• disable unwanted label declaration (SVN/CVS)
• disable auto building

reference:making-eclipse-ide-faster

for example!

const TextBold = (props) => <Text style={{fontWeight: 'bold'}}>Text bold</Text>

<Text> 123<TextBold/> </Text>

In my case, while playing video, I needed to call a function everytime currentTime of video updates. So I used timeupdate event of video and I came to know that it was fired at least 4 times a second (depends on the browser you use, see this). So I changed it to call a function every second like this:

var currentIntTime = 0;

var someFunction = function() {
    currentIntTime++;
    // Do something here
} 
vidEl.on('timeupdate', function(){
    if(parseInt(vidEl.currentTime) > currentIntTime) {
        someFunction();
    }
});

This reduces calls to someFunc by at least 1/3 and it may help your browser to behave normally. It did for me !!!

Thanks Andy W

I found that the mid() did not quite work as I expected and I modified as follows:

def mid(s, offset, amount):
    return s[offset-1:offset+amount-1]

I performed the following test:

print('[1]23', mid('123', 1, 1))
print('1[2]3', mid('123', 2, 1))
print('12[3]', mid('123', 3, 1))
print('[12]3', mid('123', 1, 2))
print('1[23]', mid('123', 2, 2))

Which resulted in:

[1]23 1
1[2]3 2
12[3] 3
[12]3 12
1[23] 23

Which was what I was expecting. The original mid() code produces this:

[1]23 2
1[2]3 3
12[3] 
[12]3 23
1[23] 3

But the left() and right() functions work fine. Thank you.

Use -A and -B switches (mean lines-after and lines-before):

grep -A 1 -B 1 FAILED file.txt

It's very simple.

1. You add an image.

2. You create a css property to this image.

   img { transition: all 0.3s ease-in-out 0s; }
   

3. You add an animation like that:

   img:hover
   {
       cursor: default;
       transform: rotate(360deg);
       transition: all 0.3s ease-in-out 0s;
   }
   

Had that issue with homebrew MacOS the problem was some sort of permission missing on /usr/local/var/log directory see issue here

In order to solve it I deleted the /usr/local/var/log and reinstall redis brew reinstall redis

Here is a code snippet taken from a blog article written by Anubhav Goyal:

// this code will mark the forms authentication cookie and the
// session cookie as Secure.
if (Response.Cookies.Count > 0)
{
    foreach (string s in Response.Cookies.AllKeys)
    {
        if (s == FormsAuthentication.FormsCookieName || "asp.net_sessionid".Equals(s, StringComparison.InvariantCultureIgnoreCase))
        {
             Response.Cookies[s].Secure = true;
        }
    }
}

Adding this to the EndRequest event handler in the global.asax should make this happen for all page calls.

Note: An edit was proposed to add a break; statement inside a successful "secure" assignment. I've rejected this edit based on the idea that it would only allow 1 of the cookies to be forced to secure and the second would be ignored. It is not inconceivable to add a counter or some other metric to determine that both have been secured and to break at that point.

You can use the base64 module to encode strings to stop shoulder surfing, but it's not going to stop someone finding your code if they have access to your files.

You can then use the compile() function and the eval() function to execute your code once you've decoded it.

>>> import base64
>>> mycode = "print 'Hello World!'"
>>> secret = base64.b64encode(mycode)
>>> secret
'cHJpbnQgJ2hlbGxvIFdvcmxkICEn'
>>> mydecode = base64.b64decode(secret)
>>> eval(compile(mydecode,'<string>','exec'))
Hello World!

So if you have 30 lines of code you'll probably want to encrypt it doing something like this:

>>> f = open('myscript.py')
>>> encoded = base64.b64encode(f.read())

You'd then need to write a second script that does the compile() and eval() which would probably include the encoded script as a string literal encased in triple quotes. So it would look something like this:

import base64
myscript = """IyBUaGlzIGlzIGEgc2FtcGxlIFB5d
              GhvbiBzY3JpcHQKcHJpbnQgIkhlbG
              xvIiwKcHJpbnQgIldvcmxkISIK"""
eval(compile(base64.b64decode(myscript),'<string>','exec'))

Custom Array adapter to hide the last item of the spinner

 import android.content.Context
 import android.widget.ArrayAdapter
 import android.widget.Spinner

 class HintAdapter<T>(context: Context, resource: Int, objects: Array<T>) :
    ArrayAdapter<T>(context, resource, objects) {

    override fun getCount(): Int {
        val count = super.getCount()
        // The last item will be the hint.
        return if (count > 0) count - 1 else count
    }
}

Spinner Extension function to set hint on spinner

fun Spinner.addHintWithArray(context: Context, stringArrayResId: Int) {
    val hintAdapter =
        HintAdapter<String>(
            context,
            android.R.layout.simple_spinner_dropdown_item,
            context.resources.getStringArray(stringArrayResId)
        )
    hintAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item)
    adapter = hintAdapter
    setSelection(hintAdapter.count)
}

How to use: add the extension by passing context and array on Spinner

spinnerMonth.addHintWithArray(context, R.array.months)

Note: The hint should be the last item of your string array

<string-array name="months">
    <item>Jan</item>
    <item>Feb</item>
    <item>Mar</item>
    <item>Apr</item>
    <item>May</item>
    <item>Months</item>
</string-array>

There is a menu shortcut to run all cells under Cell > "Run All". This isn't bound to a keyboard shortcut by default- you'll have to define your own custom binding from within the notebook, as described here.

For example, to add a keyboard binding that lets you run all the cells in a notebook, you can insert this in a cell:

%%javascript

Jupyter.keyboard_manager.command_shortcuts.add_shortcut('r', {
    help : 'run all cells',
    help_index : 'zz',
    handler : function (event) {
        IPython.notebook.execute_all_cells();
        return false;
    }}
);

If you run this code from within iPython notebook, you should find that you now have a keyboard binding to run all cells (in this case, press ctrl-M followed by r)

You can submit the form without refreshing the page, but to my knowledge it is impossible without using a JavaScript/Ajax call to a PHP script on your server. The following example uses the jQuery JavaScript library.

HTML

<form method = 'post' action = '' id = 'theForm'>
...
</form>

JavaScript

$(function() {
    $("#theForm").submit(function() {
        var data = "a=5&b=6&c=7";
        $.ajax({
            url: "path/to/php/file.php",
            data: data,
            success: function(html) {
                .. anything you want to do upon success here ..
                alert(html); // alert the output from the PHP Script
            }
        });
        return false;
    });
});

Upon submission, the anonymous Javascript function will be called, which simply sends a request to your PHP file (which will need to be in a separate file, btw). The data above needs to be a URL-encoded query string that you want to send to the PHP file (basically all of the current values of the form fields). These will appear to your server-side PHP script in the $_GET super global. An example is below.

var data = "a=5&b=6&c=7";

If that is your data string, then the PHP script will see this as:

echo($_GET['a']); // 5
echo($_GET['b']); // 6
echo($_GET['c']); // 7

You, however, will need to construct the data from the form fields as they exist for your form, such as:

var data = "user=" + $("#user").val();

(You will need to tag each form field with an 'id', the above id is 'user'.)

After the PHP script runs, the success function is called, and any and all output produced by the PHP script will be stored in the variable html.

...
success: function(html) {
    alert(html);
}
...

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

A slightly more readable alternative solution:
sys.stdout.write(code.ljust(5) + name.ljust(20) + industry)

Note that ljust(#ofchars) uses fixed width characters and doesn't dynamically adjust like the other solutions.

If you want the value you are assigning in the constructor, you need to add a method in the enum definition to return that value.

If you want a unique number that represent the enum value, you can use ordinal().

Better design would be

public static YourObject getMyObject(File configFile){
    //process and create an object configure it and return it
}

• Factory design pattern

        $content = str_replace(array("\n", "\r", "\t"), '', $response);
        $content = trim(str_replace('"', "'", $content));
        $xml = simplexml_load_string($content);
        $json = json_encode($xml);
        return json_decode($json,TRUE);

This worked for me

Kind of an anonymous lookup table rather than a long switch statement:

return (const char *[]) {
    "bananas & monkeys",
    "Round and orange", 
    "APPLE",
}[enumVal];

1) Open psql terminal.

2) Unzip/ untar the dump file.

3) Create an empty database.

4) use the following command to restore the .dump file

<database_name>-# \i <path_to_.dump_file>

With Swift 5 and iOS 12.3, according to your needs, you may choose one of the 3 following ways in order to solve your problem.

#1. Using UIView's animate(withDuration:animations:) class method

animate(withDuration:animations:) has the following declaration:

Animate changes to one or more views using the specified duration.

class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)

The Playground code below shows a possible implementation of animate(withDuration:animations:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.

#2. Using UIViewPropertyAnimator's init(duration:curve:animations:) initialiser and startAnimation() method

init(duration:curve:animations:) has the following declaration:

Initializes the animator with a built-in UIKit timing curve.

convenience init(duration: TimeInterval, curve: UIViewAnimationCurve, animations: (() -> Void)? = nil)

The Playground code below shows a possible implementation of init(duration:curve:animations:) and startAnimation() in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        let animator = UIViewPropertyAnimator(duration: 2, curve: .linear, animations: {
            self.view.layoutIfNeeded()
        })
        animator.startAnimation()
    }

}

#3. Using UIViewPropertyAnimator's runningPropertyAnimator(withDuration:delay:options:animations:completion:) class method

runningPropertyAnimator(withDuration:delay:options:animations:completion:) has the following declaration:

Creates and returns an animator object that begins running its animations immediately.

class func runningPropertyAnimator(withDuration duration: TimeInterval, delay: TimeInterval, options: UIViewAnimationOptions = [], animations: @escaping () -> Void, completion: ((UIViewAnimatingPosition) -> Void)? = nil) -> Self

The Playground code below shows a possible implementation of runningPropertyAnimator(withDuration:delay:options:animations:completion:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIViewPropertyAnimator.runningPropertyAnimator(withDuration: 2, delay: 0, options: [], animations: {
            self.view.layoutIfNeeded()

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

No, there isn't such constant.

Try the following query:

collection.update(
  { _id: id },
  { $pull: { 'contact.phone': { number: '+1786543589455' } } }
);

It will find document with the given _id and remove the phone +1786543589455 from its contact.phone array.

You can use $unset to unset the value in the array (set it to null), but not to remove it completely.

I was getting this issue intermittently, I had followed the instructions here and very similar ones elsewhere. All was configured correctly.

This page: http://sysadminwebsite.wordpress.com/2012/05/29/9/ helped me find the problem.

Basically I had duplicate CID's for the MSDTC across both servers. HKEY_CLASSES_ROOT\CID

See: http://msdn.microsoft.com/en-us/library/aa561924.aspx section Ensure that MSDTC is assigned a unique CID value

I am working with virtual servers and our server team likes to use the same image for every server. It's a simple fix and we didn't need a restart. But the DTC service did need setting to Automatic startup and did need to be started after the re-install.

Here is my solution to stop the scroll (no jQuery). I use it to disable the scroll when the side menu appears.

<button onClick="noscroll()" style="position:fixed; padding: 8px 16px;">Disable/Enable scroll</button>_x000D_
<script>_x000D_
var noscroll_var;_x000D_
function noscroll(){_x000D_
  if(noscroll_var){_x000D_
    document.getElementsByTagName("html")[0].style.overflowY = "";_x000D_
    document.body.style.paddingRight = "0";_x000D_
    noscroll_var = false_x000D_
  }else{_x000D_
    document.getElementsByTagName("html")[0].setAttribute('style', 'overflow-y: hidden !important');_x000D_
    document.body.style.paddingRight = "17px";_x000D_
    noscroll_var = true_x000D_
  }_x000D_
}/*noscroll()*/_x000D_
</script>_x000D_
_x000D_
<!-- Just to fill the page -->_x000D_
<script>_x000D_
  for(var i=0; i <= 80; i++){_x000D_
    document.write(i + "<hr>")_x000D_
  }_x000D_
</script>

I put 17px of padding-right to compensate for the disappearance of the scroll bar. But this is also problematic, mostly for mobile browsers. Solved by getting the bar width according to this.

If you are using Twig templates for Symfony, you can use the classic {{object.date_attribute.format('d/m/Y')}} to obtain the desired formatted date.

You don't need the redirection, use only

Realizing this is a bit of an old question, the responses helped me come up with a solution to testing command line arguments to a batch file; so I wanted to post my solution as well in case anyone else was looking for a similar solution.

First thing that I should point out is that I was having trouble getting IF ... ELSE statements to work inside of a FOR ... DO clause. Turns out (thanks to dbenham for inadvertently pointing this out in his examples) the ELSE statement cannot be on a separate line from the closing parens.

So instead of this:

FOR ... DO (
    IF ... (
    )
    ELSE (
    )
)

Which is my preference for readability and aesthetic reasons, you have to do this:

FOR ... DO (
    IF ... (
    ) ELSE (
    )
)

Now the ELSE statement doesn't return as an unrecognized command.

Finally, here's what I was attempting to do - I wanted to be able to pass several arguments to a batch file in any order, ignoring case, and reporting/failing on undefined arguments passed in. So here's my solution...

@ECHO OFF
SET ARG1=FALSE
SET ARG2=FALSE
SET ARG3=FALSE
SET ARG4=FALSE
SET ARGS=(arg1 Arg1 ARG1 arg2 Arg2 ARG2 arg3 Arg3 ARG3)
SET ARG=

FOR %%A IN (%*) DO (
    SET TRUE=
    FOR %%B in %ARGS% DO (
        IF [%%A] == [%%B] SET TRUE=1
        )
    IF DEFINED TRUE (
        SET %%A=TRUE
        ) ELSE (
        SET ARG=%%A
        GOTO UNDEFINED
        )
    )

ECHO %ARG1%
ECHO %ARG2%
ECHO %ARG3%
ECHO %ARG4%
GOTO END

:UNDEFINED
ECHO "%ARG%" is not an acceptable argument.
GOTO END

:END

Note, this will only report on the first failed argument. So if the user passes in more than one unacceptable argument, they will only be told about the first until it's corrected, then the second, etc.

The underline may be removed by a CSS property called text decoration.

<style>
    a {
        text-decoration:none;
    }
</style>

If you want to remove the underline for the text present in the elements other than a, the following syntax should be used.

<style>
    element-name{
        text-decoration:none;
    }
</style>

There are many other text-decoration values that may help you to design links.

This solution works with versions of date which do not support date -d @. It does not require AWK or other commands. A Unix timestamp is the number of seconds since Jan 1, 1970, UTC so it is important to specify UTC.

date -d '1970-01-01 1357004952 sec UTC'
Mon Dec 31 17:49:12 PST 2012

If you are on a Mac, then use:

date -r 1357004952

Command for getting epoch:

date +%s
1357004952

I think the performance will be quite similar. The overhead that is involved when using a List vs an Array is, IMHO when you add items to the list, and when the list has to increase the size of the array that it's using internally, when the capacity of the array is reached.

Suppose you have a List with a Capacity of 10, then the List will increase it's capacity once you want to add the 11th element. You can decrease the performance impact by initializing the Capacity of the list to the number of items it will hold.

But, in order to figure out if iterating over a List is as fast as iterating over an array, why don't you benchmark it ?

int numberOfElements = 6000000;

List<int> theList = new List<int> (numberOfElements);
int[] theArray = new int[numberOfElements];

for( int i = 0; i < numberOfElements; i++ )
{
    theList.Add (i);
    theArray[i] = i;
}

Stopwatch chrono = new Stopwatch ();

chrono.Start ();

int j;

 for( int i = 0; i < numberOfElements; i++ )
 {
     j = theList[i];
 }

 chrono.Stop ();
 Console.WriteLine (String.Format("iterating the List took {0} msec", chrono.ElapsedMilliseconds));

 chrono.Reset();

 chrono.Start();

 for( int i = 0; i < numberOfElements; i++ )
 {
     j = theArray[i];
 }

 chrono.Stop ();
 Console.WriteLine (String.Format("iterating the array took {0} msec", chrono.ElapsedMilliseconds));

 Console.ReadLine();

On my system; iterating over the array took 33msec; iterating over the list took 66msec.

To be honest, I didn't expect that the variation would be that much. So, I've put my iteration in a loop: now, I execute both iteration 1000 times. The results are:

iterating the List took 67146 msec iterating the array took 40821 msec

Now, the variation is not that large anymore, but still ...

Therefore, I've started up .NET Reflector, and the getter of the indexer of the List class, looks like this:

public T get_Item(int index)
{
    if (index >= this._size)
    {
        ThrowHelper.ThrowArgumentOutOfRangeException();
    }
    return this._items[index];
}

As you can see, when you use the indexer of the List, the List performs a check whether you're not going out of the bounds of the internal array. This additional check comes with a cost.

It completely answered on basis of "generator" type in ID while storing any entity. If value for generator is "assigned" which means you are supplying the ID. Then it makes no diff in hibernate for save or persist. You can go with any method you want. If value is not "assigned" and you are using save() then you will get ID as return from the save() operation.

Another check is if you are performing the operation outside transaction limit or not. Because persist() belongs to JPA while save() for hibernate. So using persist() outside transaction boundaries will not allow to do so and throw exception related to persistant. while with save() no such restriction and one can go with DB transaction through save() outside the transaction limit.

To open new tab using JavascriptExecutor,

((JavascriptExecutor) driver).executeScript("window.open()");
ArrayList<String> tabs = new ArrayList<String>(driver.getWindowHandles());
driver.switchTo().window(tabs.get(1));

Will control on tab as according to index:

driver.switchTo().window(tabs.get(1));

Driver control on main tab:

driver.switchTo().window(tabs.get(0));
