1. What does $rootScope.$broadcast do?

   $rootScope.$broadcast is sending an event through the application scope. Any children scope of that app can catch it using a simple: $scope.$on().

   It is especially useful to send events when you want to reach a scope that is not a direct parent (A branch of a parent for example)

   !!! One thing to not do however is to use $rootScope.$on from a controller. $rootScope is the application, when your controller is destroyed that event listener will still exist, and when your controller will be created again, it will just pile up more event listeners. (So one broadcast will be caught multiple times). Use $scope.$on() instead, and the listeners will also get destroyed.

2. What is the difference between $rootScope.$broadcast & $rootScope.$broadcast.apply?

   Sometimes you have to use apply(), especially when working with directives and other JS libraries. However since I don't know that code base, I wouldn't be able to tell if that's the case here.

Main difference between JPA and JDBC is level of abstraction.

JDBC is a low level standard for interaction with databases. JPA is higher level standard for the same purpose. JPA allows you to use an object model in your application which can make your life much easier. JDBC allows you to do more things with the Database directly, but it requires more attention. Some tasks can not be solved efficiently using JPA, but may be solved more efficiently with JDBC.

You can use

start "" "%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"

or

start "" /D "%USERPROFILE%\Desktop\BGInfo" bginfo.exe dc_bginfo.bgi

or

"%USERPROFILE%\Desktop\BGInfo\bginfo.exe" "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi"

or

cd /D "%USERPROFILE%\Desktop\BGInfo"
bginfo.exe dc_bginfo.bgi

Help on commands start and cd is output by executing in a command prompt window help start or start /? and help cd or cd /?.

But I do not understand why you need a batch file at all for starting the application with the additional parameter. Create a shortcut (*.lnk) on your desktop for this application. Then right click on the shortcut, left click on Properties and append after a space character "%USERPROFILE%\Desktop\BGInfo\dc_bginfo.bgi" as parameter.

See numpy.clip:

index = numpy.clip(index, 0, len(my_list) - 1)

With support of default methods in interface since launch of Java 8, the gap between interface and abstract classes has been reduced but still they have major differences.

1. Variables in interface are public static final. But abstract class can have other type of variables like private, protected etc

2. Methods in interface are public or public static but methods in abstract class can be private and protected too

3. Use abstract class to establish relation between interrelated objects. Use interface to establish relation between unrelated classes.

Have a look at this article for special properties of interface in java 8. static modifier for default methods in interface causes compile time error in derived error if you want to use @override.

This article explains why default methods have been introduced in java 8 : To enhance the Collections API in Java 8 to support lambda expressions.

Have a look at oracle documentation too to understand the differences in better way.

Have a look at this related SE questions with code example to understand things in better way:

How should I have explained the difference between an Interface and an Abstract class?

I spent hours on this and finally figured it out. This problem happens if service account your sender application is using differs from the service account your receiver is using.

You can find out your receiver service account via Firebase -> Project Overview -> Project Settings -> Service Accounts and generate a new key and use that key when you are initializing your FirebaseApp in the sender:

FileInputStream serviceAccount = new FileInputStream("YOUR_PATH_TO_GENERATED_KEY.json");
GoogleCredentials googleCredentials = GoogleCredentials.fromStream(serviceAccount);
FirebaseOptions options = new FirebaseOptions.Builder().setCredentials(googleCredentials).build();
firebaseApp =  FirebaseApp.initializeApp(options);

This initialization need to be done once before you send push notifications.

In my case, I had done everything correctly and I still had this problem. I had made some changes in the "google-services.json" used in the receiver app and I noticed AndroidStudio was not using my new file. The solution was so simple:

AndroidStudio -> Build -> Clean Project and Build -> Rebuild Project

A simple way to do this is to call a logging function:

DEBUG = True

def log(s):
    if DEBUG:
        print s

log("hello world")

Then you can change the value of DEBUG and run your code with or without logging.

The standard logging module has a more elaborate mechanism for this.

When you're using iOS >= 4

dispatch_async(dispatch_get_main_queue(), ^{
  //Your main thread code goes in here
  NSLog(@"Im on the main thread");       
});

First of all, check if your npm and node installed properly
with commands npm version and node -v.

If they are proper:

1. Find the root global Directory of NPM npm root -g (it will give you root of your global npm store)

2. Uninstall old angular cli with npm uninstall -g angular-cli and npm cache clean

3. Reinstall new Version of angular npm install -g @angular/cli@latest

4. make an Alias of Name ng:

alias ng="C:/ProgramData/npm/node_modules/@angular/cli/bin/ng"

alias ng="<ath-to-your-global-node-modules>/<angular cli path till ng>"
(from answered Oct 20 '16 at 15:30 @m.zemlyanoi )

then to check you can type ng -v

The simplest solution to the problem is to change your for loop statement :

Instead of using

      for (i in **0**:n))

Use

      for (i in **1**:n))

I prefer the style

(results || [, 0]) [1]

Try this query.. It uses the Analytic function SUM:

SELECT * FROM
(  
 SELECT SUM(1) OVER(PARTITION BY ctn_no) cnt, A.*
 FROM table1 a 
 WHERE s_ind ='Y'   
)
WHERE cnt > 2

Am not sure why you are identifying a record as a duplicate if the ctn_no repeats more than 2 times. FOr me it repeats more than once it is a duplicate. In this case change the las part of the query to WHERE cnt > 1

you should try:

request.url 

It suppose to work always, even on localhost (just did it).

It seems like you installed a zip version of sbt, which is fine. But I suggest you install the native debian package if you are on Ubuntu. That is how I managed to install it on my Ubuntu 12.04. Check it out here: http://www.scala-sbt.org/release/docs/Installing-sbt-on-Linux.html Or simply directly download it from here.

To get information about the current store from anywhere in Magento, use:

<?php
$store = Mage::app()->getStore();

This will give you a Mage_Core_Model_Store object, which has some of the information you need:

<?php
$name = $store->getName();

As for your other question about line number, I'm not sure what you mean. If you mean that you want to know what line number in the code you are on (for error handling, for instance), try:

<?php
$line      = __LINE__;
$file      = __FILE__;
$class     = __CLASS__;
$method    = __METHOD__;
$namespace = __NAMESPACE__;

It is important to know, that the VALUE box is only allowed to contain a numeral value (no specifiers).

If you want to send e.g. an array of "messages" with Postman, each having a list of key/value pairs, enter e.g. messages[][reason] into the KEY box and the value of reason into the VALUE box:

The server will receive:

{"messages"=>[{"reason"=>"scrolled", "tabid"=>"2"}, {"reason"=>"reload", "tabid"=>"1"}], "endpoint"=>{}}

I tried out the filters referenced above and strongly disliked the effect it created. I also didn't want to use any plugins since they'd slow down loading time for what seems like such a basic effect.

In my case I was looking for a text shadow with a 0px blur, which means the shadow is an exact replica of the text but just offset and behind. This effect can be easily recreated with jquery.

<script>
    var shadowText = $(".ie9 .normalText").html();  
    $(".ie9 .normalText").before('<div class="shadow">' + shadowText + '</div>');
</script>
<style>
    .ie9 .shadow { position: relative; top: 2px; left: -3px; }
</style>

This will create an identical effect to the css3 text-shadow below.

    text-shadow: -3px 2px 0px rgba(0, 0, 0, 1.0);

here's a working example (see the large white text over the main banner image) http://www.cb.restaurantconnectinc.com/

Try this code.

public void send (String fileName) {
    String SFTPHOST = "host:IP";
    int SFTPPORT = 22;
    String SFTPUSER = "username";
    String SFTPPASS = "password";
    String SFTPWORKINGDIR = "file/to/transfer";

    Session session = null;
    Channel channel = null;
    ChannelSftp channelSftp = null;
    System.out.println("preparing the host information for sftp.");

    try {
        JSch jsch = new JSch();
        session = jsch.getSession(SFTPUSER, SFTPHOST, SFTPPORT);
        session.setPassword(SFTPPASS);
        java.util.Properties config = new java.util.Properties();
        config.put("StrictHostKeyChecking", "no");
        session.setConfig(config);
        session.connect();
        System.out.println("Host connected.");
        channel = session.openChannel("sftp");
        channel.connect();
        System.out.println("sftp channel opened and connected.");
        channelSftp = (ChannelSftp) channel;
        channelSftp.cd(SFTPWORKINGDIR);
        File f = new File(fileName);
        channelSftp.put(new FileInputStream(f), f.getName());
        log.info("File transfered successfully to host.");
    } catch (Exception ex) {
        System.out.println("Exception found while tranfer the response.");
    } finally {
        channelSftp.exit();
        System.out.println("sftp Channel exited.");
        channel.disconnect();
        System.out.println("Channel disconnected.");
        session.disconnect();
        System.out.println("Host Session disconnected.");
    }
}   

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

You can target the first child element with just using CSS selector with jQuery:

$(this).children('img:nth-child(1)');

If you want to target the second child element just change 1 to 2:

$(this).children('img:nth-child(2)');

and so on..

if you want to target more elements, you can use a for loop:

for (i = 1; i <= $(this).children().length; i++) {
    let childImg =  $(this).children("img:nth-child("+ i +")");
    // Do stuff...
}

Based on Henk's answer I have been able to come up with the specific domain, the method I want to allow and also the header I want to enable CORS for:

public void ConfigureServices(IServiceCollection services)
{
    services.AddCors(options =>
         options.AddPolicy("AllowSpecific", p => p.WithOrigins("http://localhost:1233")
                                                   .WithMethods("GET")
                                                   .WithHeaders("name")));
    services.AddMvc();
}

usage:

[EnableCors("AllowSpecific")]

Personally I use BNC Advanced Feed Parser- i like the template system that is very easy to use

Open your storyboard file where your viewController exists, or XIB related file with textEdit.app and check if the storyboard or XIB name is the same of your viewController, then change it, save and reload/restart Xcode.

try this for Pakistani users .Here's a fairly compact one I created.

((\+92)|0)[.\- ]?[0-9][.\- ]?[0-9][.\- ]?[0-9]

Tested against the following use cases.

+92 -345 -123 -4567
+92 333 123 4567
+92 300 123 4567
+92 321 123 -4567
+92 345 - 540 - 5883

Consider this example:

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|")));
    // output : [Real, How, To]
  }
}

The result does not include the empty strings between the "|" separator. To keep the empty strings :

public class StringSplit {
  public static void main(String args[]) throws Exception{
    String testString = "Real|How|To|||";
    System.out.println
       (java.util.Arrays.toString(testString.split("\\|", -1)));
    // output : [Real, How, To, , , ]
  }
}

Anyone looking for this functionality past 2018: it's much cleaner to do this with just CSS using position: sticky.

position: sticky doesn't work with some table elements (thead/tr) in Chrome. You can move sticky to tds/ths of tr you need to be sticky. Like this:

thead tr:nth-child(1) th {
  background: white;
  position: sticky;
  top: 0;
  z-index: 10;
}

Yes, there is: https://github.com/robinrowe/libunistd

Clone the repository and add path\to\libunistd\unistd to the INCLUDE environment variable.

Yes, but the syntax is different than what you have

SELECT
    <fields>
FROM
    <table1>
    LEFT JOIN <table2>
        ON <criteria for join>
        AND <other criteria for join>
    LEFT JOIN <table3> 
        ON <criteria for join>
        AND <other criteria for join>

in this code data is a two dimensional array of table data

let oTable = document.getElementById('datatable-id');
let data = [...oTable.rows].map(t => [...t.children].map(u => u.innerText))

Also, the apt-show-versions package (installed separately) parses dpkg information about what is installed and tells you if packages are up to date.

Example..

$ sudo apt-show-versions --regex chrome
google-chrome-stable/stable upgradeable from 32.0.1700.102-1 to 35.0.1916.114-1
xserver-xorg-video-openchrome/quantal-security uptodate 1:0.3.1-0ubuntu1.12.10.1

If you want beautiful and responsive alert dialog then you can use flutter packages like

rflutter alert ,fancy dialog,rich alert,sweet alert dialogs,easy dialog & easy alert

These alerts are good looking and responsive. Among them rflutter alert is the best. currently I am using rflutter alert for my apps.

My approach is very close to Garret Wilson's (thanks, I voted you up ;)

In addition it provides downward compatibility with Android < 3.

I just recognized that my solution is even closer to the one by Kevin Remo. It's just a wee bit cleaner (as it does not rely on the "expection" antipattern).

public class MyPreferenceActivity extends PreferenceActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.HONEYCOMB) {
            onCreatePreferenceActivity();
        } else {
            onCreatePreferenceFragment();
        }
    }

    /**
     * Wraps legacy {@link #onCreate(Bundle)} code for Android < 3 (i.e. API lvl
     * < 11).
     */
    @SuppressWarnings("deprecation")
    private void onCreatePreferenceActivity() {
        addPreferencesFromResource(R.xml.preferences);
    }

    /**
     * Wraps {@link #onCreate(Bundle)} code for Android >= 3 (i.e. API lvl >=
     * 11).
     */
    @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    private void onCreatePreferenceFragment() {
        getFragmentManager().beginTransaction()
                .replace(android.R.id.content, new MyPreferenceFragment ())
                .commit();
    }
}

For a "real" (but more complex) example see NusicPreferencesActivity and NusicPreferencesFragment.

I know the question is old, but if someone is looking for a great new android color picker that use material design I have forked an great project from github and made a simple-to-use android color picker dialog.

This is the project: Android Color Picker

Android Color Picker dialog

HOW TO USE IT

Adding the library to your project

The aar artifact is available at the jcenter repository. Declare the repository and the dependency in your build.gradle.

(root)

repositories {
    jcenter()
}

(module)

dependencies {
    compile 'com.pes.materialcolorpicker:library:1.0.2'
}

Use the library

Create a color picker dialog object

final ColorPicker cp = new ColorPicker(MainActivity.this, defaultColorR, defaultColorG, defaultColorB);

defaultColorR, defaultColorG, defaultColorB are 3 integer ( value 0-255) for the initialization of the color picker with your custom color value. If you don't want to start with a color set them to 0 or use only the first argument

Then show the dialog (when & where you want) and save the selected color

/* Show color picker dialog */
cp.show();

/* On Click listener for the dialog, when the user select the color */
Button okColor = (Button)cp.findViewById(R.id.okColorButton);

okColor.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
            
        /* You can get single channel (value 0-255) */
        selectedColorR = cp.getRed();
        selectedColorG = cp.getGreen();
        selectedColorB = cp.getBlue();
            
        /* Or the android RGB Color (see the android Color class reference) */
        selectedColorRGB = cp.getColor();

        cp.dismiss();
    }
});

That's all :)

As of September 2019 pywin32 is now available from PyPI and installs the latest version (currently version 224). This is done via the pip command

pip install pywin32

If you wish to get an older version the sourceforge link below would probably have the desired version, if not you can use the command, where xxx is the version you require, e.g. 224

pip install pywin32==xxx

This differs to the pip command below as that one uses pypiwin32 which currently installs an older (namely 223)

Browsing the docs I see no reason for these commands to work for all python3.x versions, I am unsure on python2.7 and below so you would have to try them and if they do not work then the solutions below will work.

Probably now undesirable solutions but certainly still valid as of September 2019

There is no version of specific version ofwin32api. You have to get the pywin32module which currently cannot be installed via pip. It is only available from this link at the moment.

https://sourceforge.net/projects/pywin32/files/pywin32/Build%20220/

The install does not take long and it pretty much all done for you. Just make sure to get the right version of it depending on your python version :)

EDIT

Since I posted my answer there are other alternatives to downloading the win32api module.

It is now available to download through pip using this command;

pip install pypiwin32

Also it can be installed from this GitHub repository as provided in comments by @Heath

I had the same problem with the bootstrap 3 and solved like this:

$('#myModal').on('shown.bs.modal', function (e) {
    $(this).find('input[type=text]:visible:first').focus();
})

$('#myModal').modal('show').trigger('shown');

Try this:

SELECT  DATEDIFF(dd, 0,GETDATE()) + CONVERT(DATETIME,'03:30:00.000')

For anyone that has this issue in the future, for me it was caused by an arrow function instead of a function literal in a run block:

// bad
module('a').run(() => ...)

// good
module('a').run(function() {...})

#div-name

{

  background-image: url('../images/background-art-main.jpg');
  background-position: top right 50px;
  background-repeat: no-repeat;
}

A pointer-to-member allows you to write a single comparator, which can work with any data member of your class:

#include <algorithm>
#include <vector>
#include <string>
#include <iostream>

template <typename T, typename U>
struct CompareByMember {
    // This is a pointer-to-member, it represents a member of class T
    // The data member has type U
    U T::*field;
    CompareByMember(U T::*f) : field(f) {}
    bool operator()(const T &lhs, const T &rhs) {
        return lhs.*field < rhs.*field;
    }
};

struct Test {
    int a;
    int b;
    std::string c;
    Test(int a, int b, std::string c) : a(a), b(b), c(c) {}
};

// for convenience, this just lets us print out a Test object
std::ostream &operator<<(std::ostream &o, const Test &t) {
    return o << t.c;
}

int main() {
    std::vector<Test> vec;
    vec.push_back(Test(1, 10, "y"));
    vec.push_back(Test(2, 9, "x"));

    // sort on the string field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,std::string>(&Test::c));
    std::cout << "sorted by string field, c: ";
    std::cout << vec[0] << " " << vec[1] << "\n";

    // sort on the first integer field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,int>(&Test::a));
    std::cout << "sorted by integer field, a: ";
    std::cout << vec[0] << " " << vec[1] << "\n";

    // sort on the second integer field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,int>(&Test::b));
    std::cout << "sorted by integer field, b: ";
    std::cout << vec[0] << " " << vec[1] << "\n";
}

Output:

sorted by string field, c: x y
sorted by integer field, a: y x
sorted by integer field, b: x y

Using

border: none;

doesn't work in some versions of IE. IE9 is fine but in previous versions it displays the border even when the style is "none". I experienced this when using a print stylesheet where I didn't want borders on the input boxes.

border: 0;

seems to work fine in all browsers.

This post can help you as a little bit related :

Using RegEX To Prefix And Append In Notepad++

Assuming alphanumeric words, you can use:

Search = ^([A-Za-z0-9]+)$ Replace = able:"\1"

Or, if you just want to highlight the lines and use "Replace All" & "In Selection" (with the same replace):

Search = ^(.+)$

^ points to the start of the line. $ points to the end of the line.

\1 will be the source match within the parentheses.

Use Python 2.7, is has more 3rd party libs at the moment. (Edit: see below).

I recommend you using the stdlib module urllib2, it will allow you to comfortably get web resources. Example:

import urllib2

response = urllib2.urlopen("http://google.de")
page_source = response.read()

For parsing the code, have a look at BeautifulSoup.

BTW: what exactly do you want to do:

Just for background, I need to download a page and replace any img with ones I have

Edit: It's 2014 now, most of the important libraries have been ported, and you should definitely use Python 3 if you can. python-requests is a very nice high-level library which is easier to use than urllib2.

New Cpanels block to see the .htaccess file or if you add a .user.ini you wont be able to see it. but with a little hack you can make it work. Edit for example wp-config.php and in the URL bar replace wp-config.php by .htaccess now you can paste the values and save it. enter image description here

For anyone else who stumbles across this thread but needs to find or create an object with attributes that might change depending on the circumstances, add the following method to your model:

# Return the first object which matches the attributes hash
# - or -
# Create new object with the given attributes
#
def self.find_or_create(attributes)
  Model.where(attributes).first || Model.create(attributes)
end

Optimization tip: regardless of which solution you choose, consider adding indexes for the attributes you are querying most frequently.

select t1.*, sq.*
from table1 t1,
   (select a,b,c from table2 ...) sq

Addition: SQL Server 2012 shows some improved performance in this area but doesn't seem to tackle the specific issues noted below. This should apparently be fixed in the next major version after SQL Server 2012!

Your plan shows the single inserts are using parameterised procedures (possibly auto parameterised) so parse/compile time for these should be minimal.

I thought I'd look into this a bit more though so set up a loop (script) and tried adjusting the number of VALUES clauses and recording the compile time.

I then divided the compile time by the number of rows to get the average compile time per clause. The results are below

Up until 250 VALUES clauses present the compile time / number of clauses has a slight upward trend but nothing too dramatic.

But then there is a sudden change.

That section of the data is shown below.

The cached plan size which had been growing linearly suddenly drops but CompileTime increases 7 fold and CompileMemory shoots up. This is the cut off point between the plan being an auto parametrized one (with 1,000 parameters) to a non parametrized one. Thereafter it seems to get linearly less efficient (in terms of number of value clauses processed in a given time).

Not sure why this should be. Presumably when it is compiling a plan for specific literal values it must perform some activity that does not scale linearly (such as sorting).

It doesn't seem to affect the size of the cached query plan when I tried a query consisting entirely of duplicate rows and neither affects the order of the output of the table of the constants (and as you are inserting into a heap time spent sorting would be pointless anyway even if it did).

Moreover if a clustered index is added to the table the plan still shows an explicit sort step so it doesn't seem to be sorting at compile time to avoid a sort at run time.

I tried to look at this in a debugger but the public symbols for my version of SQL Server 2008 don't seem to be available so instead I had to look at the equivalent UNION ALL construction in SQL Server 2005.

So going off the names in the stack trace it appears to spend a lot of time comparing strings.

This KB article indicates that DeriveNormalizedGroupProperties is associated with what used to be called the normalization stage of query processing

This stage is now called binding or algebrizing and it takes the expression parse tree output from the previous parse stage and outputs an algebrized expression tree (query processor tree) to go forward to optimization (trivial plan optimization in this case) [ref].

I tried one more experiment (Script) which was to re-run the original test but looking at three different cases.

1. First Name and Last Name Strings of length 10 characters with no duplicates.
2. First Name and Last Name Strings of length 50 characters with no duplicates.
3. First Name and Last Name Strings of length 10 characters with all duplicates.

It can clearly be seen that the longer the strings the worse things get and that conversely the more duplicates the better things get. As previously mentioned duplicates don't affect the cached plan size so I presume that there must be a process of duplicate identification when constructing the algebrized expression tree itself.

Edit

One place where this information is leveraged is shown by @Lieven here

SELECT * 
FROM (VALUES ('Lieven1', 1),
             ('Lieven2', 2),
             ('Lieven3', 3))Test (name, ID)
ORDER BY name, 1/ (ID - ID) 

Because at compile time it can determine that the Name column has no duplicates it skips ordering by the secondary 1/ (ID - ID) expression at run time (the sort in the plan only has one ORDER BY column) and no divide by zero error is raised. If duplicates are added to the table then the sort operator shows two order by columns and the expected error is raised.

Most answers here focused on how to check if a collection is Empty or Null which was quite straight forward as demonstrated by them.

Like many people here, I was also wondering why does not Microsoft itself provide such a basic feature which is already provided for String type (String.IsNullOrEmpty())? Then I encountered this guideline from Microsoft where it says:

X DO NOT return null values from collection properties or from methods returning collections. Return an empty collection or an empty array instead.

The general rule is that null and empty (0 item) collections or arrays should be treated the same.

So, ideally you should never have a collection which is null if you follow this guideline from Microsoft. And that will help you to remove unnecessary null checking which ultimately will make your code more readable. In this case, someone just need to check : myList.Any() to find out whether there is any element present in the list.

Hope this explanation will help someone who will face same problem in future and wondering why isn't there any such feature to check whether a collection is null or empty.

Change the adapter type in VirtualBox to bridged, and set the guest to use DHCP or set a static IP address outside of the bounds of DHCP. This will cause the Virtual Machine to act like a normal guest on your home network. You can then port forward.

Try This:

using System;
using System.Configuration;
using System.Web.Configuration;

namespace SampleApplication.WebConfig
{
    public partial class webConfigFile : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            //Helps to open the Root level web.config file.
            Configuration webConfigApp = WebConfigurationManager.OpenWebConfiguration("~");
            //Modifying the AppKey from AppValue to AppValue1
            webConfigApp.AppSettings.Settings["ConnectionString"].Value = "ConnectionString";
            //Save the Modified settings of AppSettings.
            webConfigApp.Save();
        }
    }
}

Use in XML:

android:src="@drawable/image"

imageView.setImageDrawable(ContextCompat.getDrawable(activity, R.drawable.your_image));

This answer expounds on John Black's helpful answer, so I will repeat some of his answer content in my answer.

The easiest way to resize a marker seems to be leaving argument 2, 3, and 4 null and scaling the size in argument 5.

var pinIcon = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_letter&chld=%E2%80%A2|FFFF00",
    null, /* size is determined at runtime */
    null, /* origin is 0,0 */
    null, /* anchor is bottom center of the scaled image */
    new google.maps.Size(42, 68)
);  

As an aside, this answer to a similar question asserts that defining marker size in the 2nd argument is better than scaling in the 5th argument. I don't know if this is true.

Leaving arguments 2-4 null works great for the default google pin image, but you must set an anchor explicitly for the default google pin shadow image, or it will look like this:

The bottom center of the pin image happens to be collocated with the tip of the pin when you view the graphic on the map. This is important, because the marker's position property (marker's LatLng position on the map) will automatically be collocated with the visual tip of the pin when you leave the anchor (4th argument) null. In other words, leaving the anchor null ensures the tip points where it is supposed to point.

However, the tip of the shadow is not located at the bottom center. So you need to set the 4th argument explicitly to offset the tip of the pin shadow so the shadow's tip will be colocated with the pin image's tip.

By experimenting I found the tip of the shadow should be set like this: x is 1/3 of size and y is 100% of size.

var pinShadow = new google.maps.MarkerImage(
    "http://chart.apis.google.com/chart?chst=d_map_pin_shadow",
    null,
    null,
    /* Offset x axis 33% of overall size, Offset y axis 100% of overall size */
    new google.maps.Point(40, 110), 
    new google.maps.Size(120, 110)); 

to give this:

we can do it with a single line of code.

 user1 = pd.read_csv('dataset/1.csv', names=['TIME', 'X', 'Y', 'Z'], header=None)

I'm not sure I agree with inheritance from ValueError -- my interpretation of the documentation is that ValueError is only supposed to be raised by builtins... inheriting from it or raising it yourself seems incorrect.

Raised when a built-in operation or function receives an argument that has the right type but an inappropriate value, and the situation is not described by a more precise exception such as IndexError.

On the tab "Workloads" check ".Net Core cross-platform development" and click on "Modify"

Don't forget to check ".NET Core 2.0 development tools" on the left menu.

Let me to recommend you a jQuery plugin for nice modal alers. It doesn't requires jquery UI.

Demo: http://www.webmasters.by/images/articles/jquery.alerts/index.html

The same can be done without DataTrigger too:

 <DataGrid.RowStyle>
     <Style TargetType="DataGridRow">
         <Setter Property="Background" >
             <Setter.Value>
                 <Binding Path="State" Converter="{StaticResource BooleanToBrushConverter}">
                     <Binding.ConverterParameter>
                         <x:Array Type="SolidColorBrush">
                             <SolidColorBrush Color="{StaticResource RedColor}"/>
                             <SolidColorBrush Color="{StaticResource TransparentColor}"/>
                         </x:Array>
                     </Binding.ConverterParameter>
                 </Binding>
             </Setter.Value>
         </Setter>
     </Style>
 </DataGrid.RowStyle>

Where BooleanToBrushConverter is the following class:

public class BooleanToBrushConverter : IValueConverter
{
    public object Convert(object value, Type targetType, object parameter, CultureInfo culture)
    {
        if (value == null)
            return Brushes.Transparent;

        Brush[] brushes = parameter as Brush[];
        if (brushes == null)
            return Brushes.Transparent;

        bool isTrue;
        bool.TryParse(value.ToString(), out isTrue);

        if (isTrue)
        {
            var brush =  (SolidColorBrush)brushes[0];
            return brush ?? Brushes.Transparent;
        }
        else
        {
            var brush = (SolidColorBrush)brushes[1];
            return brush ?? Brushes.Transparent;
        }
    }

    public object ConvertBack(object value, Type targetType, object parameter, CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

you can declare your component like this:

const MyComponent: React.FunctionComponent = (props) => {
    return props.children;
}

@Gajus Kuizinas and @CodeHater are correct. Here i am just giving an example. While we are working with ng-if, if the assigned value is false then the whole html elements will be removed from DOM. and if assigned value is true, then the html elements will be visible on the DOM. And the scope will be different compared to the parent scope. But in case of ng-show, it wil just show and hide the elements based on the assigned value. But it always stays in the DOM. Only the visibility changes as per the assigned value.

http://plnkr.co/edit/3G0V9ivUzzc8kpLb1OQn?p=preview

Hope this example will help you in understanding the scopes. Try giving false values to ng-show and ng-if and check the DOM in console. Try entering the values in the input boxes and observe the difference.

<!DOCTYPE html>

Hello Plunker!

<input type="text" ng-model="data">
<div ng-show="true">
    <br/>ng-show=true :: <br/><input type="text" ng-model="data">
</div>
<div ng-if="true">
    <br/>ng-if=true :: <br/><input type="text" ng-model="data">
</div> 
{{data}}

OK, figured it out now - thanks to Jobi whose answer was close, but not quite.

From a WPF application, here's my code that works:

First a helper class:

private class OldWindow : System.Windows.Forms.IWin32Window
{    
    IntPtr _handle;    
    public OldWindow(IntPtr handle)
    {
        _handle = handle;
    }   

    #region IWin32Window Members    
    IntPtr System.Windows.Forms.IWin32Window.Handle
    {
        get { return _handle; }
    }    
    #endregion
}

Then, to use this:

    System.Windows.Forms.FolderBrowserDialog dlg = new FolderBrowserDialog();
    HwndSource source = PresentationSource.FromVisual(this) as HwndSource;
    System.Windows.Forms.IWin32Window win = new OldWindow(source.Handle);
    System.Windows.Forms.DialogResult result = dlg.ShowDialog(win);

I'm sure I can wrap this up better, but basically it works. Yay! :-)

I try to get in the habit of using HostingEnvironment instead of Server as it works within the context of WCF services too.

 HostingEnvironment.MapPath(@"~/App_Data/PriceModels.xml");

function setSelectedIndex(s, v) {
    for ( var i = 0; i < s.options.length; i++ ) {
        if ( s.options[i].value == v ) {
            s.options[i].selected = true;
            return;
        }
    }
}

Where s is the dropdown and v is the value

find . -type d -print0 | xargs -0 -n 1 my_command

I looked thru the answers above, I recommend pejman's Dec 29 '16 at 13:31 suggestion but he/she has not left a full answer. Here it is, I will put this as --> (you need a service and a listener $watch on one of the scopes from controllers for changes in the service area)

var app = 
angular.module('myApp', ['ngRoute', 'ngSanitize']);

app.service('bridgeService', function () {
    var msg = ""; 
    return msg;
});
app.controller('CTRL_1'
, function ($scope, $http, bridgeService) 
{
    $http.get(_restApi, config)
    .success(
    function (serverdata, status, config) {
        $scope.scope1Box = bridgeService.msg = serverdata;
    });
});
app.controller('CTRL_2'

If you don't mind importing the json module, then the best way to handle it is through json.JSONDecodeError (or json.decoder.JSONDecodeError as they are the same) as using default errors like ValueError could catch also other exceptions not necessarily connected to the json decode one.

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want

//EDIT (Oct 2020):

As @Jacob Lee noted in the comment, there could be the basic common TypeError raised when the JSON object is not a str, bytes, or bytearray. Your question is about JSONDecodeError, but still it is worth mentioning here as a note; to handle also this situation, but differentiate between different issues, the following could be used:

from json.decoder import JSONDecodeError


try:
    qByUser = byUsrUrlObj.read()
    qUserData = json.loads(qByUser).decode('utf-8')
    questionSubjs = qUserData["all"]["questions"]
except JSONDecodeError as e:
    # do whatever you want
except TypeError as e:
    # do whatever you want in this case

mappedby="object of entity of same class created in another class”

Note:-Mapped by can be used only in one class because one table must contain foreign key constraint. if mapped by can be applied on both side then it remove foreign key from both table and without foreign key there is no relation b/w two tables.

Note:- it can be use for following annotations:- 1.@OneTone 2.@OneToMany 3.@ManyToMany

Note---It cannot be use for following annotation :- 1.@ManyToOne

In one to one :- Perform at any side of mapping but perform at only one side . It will remove the extra column of foreign key constraint on the table on which class it is applied.

For eg . If we apply mapped by in Employee class on employee object then foreign key from Employee table will be removed.

Import specific methods inside of curly brackets

import { map, tail, times, uniq } from 'lodash';

Pros:

• Only one import line(for a decent amount of functions)
• More readable usage: map() instead of _.map() later in the javascript code.

Cons:

• Every time we want to use a new function or stop using another - it needs to be maintained and managed

Set your container's width in px and add:

margin: 0 auto;

Reference.

not 100% sure, as I didn't test EVERY option here, but of the ones I did test, this one is the fastest. timed it with stopwatch and it showed 9-10 ticks so if speed is more important than security, try this:

 private static Random random = new Random(); 
 public static string Random(int length)
     {   
          var stringChars = new char[length];

          for (int i = 0; i < length; i++)
              {
                  stringChars[i] = (char)random.Next(0x30, 0x7a);                  
                  return new string(stringChars);
              }
     }

Here is an example:

HTML code:

<img id="myImg" src="http://static.jquery.com/files/rocker/images/logo_jquery_215x53.gif"/>

JavaScript code:

$(document).ready(function() {
    $( "#myImg" ).mouseover(function(){
        $(this).attr("src", "http://www.jqueryui.com/images/logo.gif");
    });

    $( "#myImg" ).mouseout(function(){
        $(this).attr("src", "http://static.jquery.com/files/rocker/images/logo_jquery_215x53.gif");
    });
});

Edit: Sorry, your code was a bit strange. Now I understood what you were doing. ;) The hover method is better, of course.

Box-Muller implementation:

#include <cstdlib>
#include <cmath>
#include <ctime>
#include <iostream>
using namespace std;
 // return a uniformly distributed random number
double RandomGenerator()
{
  return ( (double)(rand()) + 1. )/( (double)(RAND_MAX) + 1. );
}
 // return a normally distributed random number
double normalRandom()
{
  double y1=RandomGenerator();
  double y2=RandomGenerator();
  return cos(2*3.14*y2)*sqrt(-2.*log(y1));
}

int main(){
double sigma = 82.;
double Mi = 40.;
  for(int i=0;i<100;i++){
double x = normalRandom()*sigma+Mi;
    cout << " x = " << x << endl;
  }
  return 0;
}

Not sure about the exact reproduction steps for the error (HRESULT E_FAIL has been returned from a call to a COM component), but the solution for me was:

1. Close Visual Studio and Repair it through Control Panel.
2. Restart system

After the restart, the error was gone.

You need to escape the % with another...

I had the same problem with a client of my company, the problem was that the driver sqljdbc4.jar, tries a convertion of character between the database and the driver. Each time that it did a request to the database, now you can imagine 650 connections concurrently, this did my sistem very very slow, for avoid this situation i add at the String of connection the following parameter:

 SendStringParametersAsUnicode=false, then te connection must be something like url="jdbc:sqlserver://IP:PORT;DatabaseName=DBNAME;SendStringParametersAsUnicode=false"

After that, the system is very very fast, as the users are very happy with the change, i hope my input be of same.

I've been trying to get my ASP.NET MVC controller to parse some model that i submitted to it using Postman.

I needed the following to get it to work:

• controller action

  [HttpPost]
  [PermitAllUsers]
  [Route("Models")]
  public JsonResult InsertOrUpdateModels(Model entities)
  {
      // ...
      return Json(response, JsonRequestBehavior.AllowGet);
  }
  

• a Models class

  public class Model
  {
      public string Test { get; set; }
      // ...
  }
  

• headers for Postman's request, specifically, Content-Type

  

• json in the request body

  

You could create a unique index with a coalesce on the MenuId:

CREATE UNIQUE INDEX
Favorites_UniqueFavorite ON Favorites
(UserId, COALESCE(MenuId, '00000000-0000-0000-0000-000000000000'), RecipeId);

You'd just need to pick a UUID for the COALESCE that will never occur in "real life". You'd probably never see a zero UUID in real life but you could add a CHECK constraint if you are paranoid (and since they really are out to get you...):

alter table Favorites
add constraint check
(MenuId <> '00000000-0000-0000-0000-000000000000')

Instead of just doing this quoted method from https://stackoverflow.com/a/4635440/3787376,

You can do something like this:

// show loading image
$('#loader_img').show();

// main image loaded ?
$('#main_img').on('load', function(){
  // hide/remove the loading image
  $('#loader_img').hide();
});

You assign load event to the image which fires when image has finished loading. Before that, you can show your loader image.

you can use a different jQuery function to make the loading image fade away, then be hidden:

// Show the loading image.
$('#loader_img').show();

// When main image loads:
$('#main_img').on('load', function(){
  // Fade out and hide the loading image.
  $('#loader_img').fadeOut(100); // Time in milliseconds.
});

"Once the opacity reaches 0, the display style property is set to none." http://api.jquery.com/fadeOut/

Or you could not use the jQuery library because there are already simple cross-browser JavaScript methods.

An example statement that uses a sub-select :

select * into MyNewTable
from
(
select 
  * 
from 
[SomeOtherTablename]
where 
  EventStartDatetime >= '01/JAN/2018' 
)
) mysourcedata
;

note that the sub query must be given a name .. any name .. e.g. above example gives the subquery a name of mysourcedata. Without this a syntax error is issued in SQL*server 2012.

The database should reply with a message like: (9999 row(s) affected)

Solution:

use incognito new tab then test it again.

reason:

in my case another user logged in with my admin panel

You can simply use Request["recipient"] to "read the HTTP values sent by a client during a Web request"

To access data from the QueryString, Form, Cookies, or ServerVariables collections, you can write Request["key"]

Update: Summarizing conversation

In order to view the values that MailGun is posting to your site you will need to read them from the web request that MailGun is making, record them somewhere and then display them on your page.

You should have one endpoint where MailGun will send the POST values to and another page that you use to view the recorded values.

It appears that right now you have one page. So when you view this page, and you read the Request values, you are reading the values from YOUR request, not MailGun.

An alternative to:

scriptPath=$(dirname $0)

is:

scriptPath=${0%/*}

.. the advantage being not having the dependence on dirname, which is not a built-in command (and not always available in emulators)

This answer is a follow up to DaRKoN_'s answer that utilized the object filter:

[ObjectFilter(Param = "postdata", RootType = typeof(ObjectToSerializeTo))]
    public JsonResult ControllerMethod(ObjectToSerializeTo postdata) { ... }

I was having a problem figuring out how to send multiple parameters to an action method and have one of them be the json object and the other be a plain string. I'm new to MVC and I had just forgotten that I already solved this problem with non-ajaxed views.

What I would do if I needed, say, two different objects on a view. I would create a ViewModel class. So say I needed the person object and the address object, I would do the following:

public class SomeViewModel()
{
     public Person Person { get; set; }
     public Address Address { get; set; }
}

Then I would bind the view to SomeViewModel. You can do the same thing with JSON.

[ObjectFilter(Param = "jsonViewModel", RootType = typeof(JsonViewModel))] // Don't forget to add the object filter class in DaRKoN_'s answer.
public JsonResult doJsonStuff(JsonViewModel jsonViewModel)
{
     Person p = jsonViewModel.Person;
     Address a = jsonViewModel.Address;
     // Do stuff
     jsonViewModel.Person = p;
     jsonViewModel.Address = a;
     return Json(jsonViewModel);
}

Then in the view you can use a simple call with JQuery like this:

var json = { 
    Person: { Name: "John Doe", Sex: "Male", Age: 23 }, 
    Address: { Street: "123 fk st.", City: "Redmond", State: "Washington" }
};

$.ajax({
     url: 'home/doJsonStuff',
     type: 'POST',
     contentType: 'application/json',
     dataType: 'json',
     data: JSON.stringify(json), //You'll need to reference json2.js
     success: function (response)
     {
          var person = response.Person;
          var address = response.Address;
     }
});

I would also use navigation.navigate. If someone has the same problem and also uses nested navigators, this is how it would work:

onPress={() =>
        navigation.navigate('MyStackScreen', {
          // Passing params to NESTED navigator screen:
          screen: 'goToScreenA',
          params: { Data: data.item },
        })
      }

Check current scrollTop vs previous scrollTop

var lastScrollTop = 0;
$(window).scroll(function(event){
   var st = $(this).scrollTop();
   if (st > lastScrollTop){
       // downscroll code
   } else {
      // upscroll code
   }
   lastScrollTop = st;
});

Are you sure, you want to do that? Even css and js files and images and ...?

OK, first check if mod_access in installed to apache, then add the following to your .htaccess:

Order Deny,Allow
Deny from all
Allow from 127.0.0.1

<Files /index.php>
    Order Allow,Deny
    Allow from all
</Files>

The first directive forbids access to any files except from localhost, because of Order Deny,Allow, Allow gets applied later, the second directive only affects index.php.

Caveat: No space after the comma in the Order line.

To allow access to files matching *.css or *.js use this directive:

<FilesMatch ".*\.(css|js)$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

You cannot use directives for <Location> or <Directory> inside .htaccess files, though.

Your option would be to use <FilesMatch ".*\.php$"> around the first allow,deny group and then explicitely allow access to index.php.

Update for Apache 2.4: This answer is correct for Apache 2.2. In Apache 2.4 the access control paradigm has changed, and the correct syntax is to use Require all denied.

var dictionary = (from x in y 
                  select new SomeClass
                  {
                      prop1 = value1,
                      prop2 = value2
                  }
                  ).ToDictionary(item => item.prop1);

That's assuming that SomeClass.prop1 is the desired Key for the dictionary.

import os

os.system("python myOtherScript.py arg1 arg2 arg3")  

Using os you can make calls directly to your terminal. If you want to be even more specific you can concatenate your input string with local variables, ie.

command = 'python myOtherScript.py ' + sys.argv[1] + ' ' + sys.argv[2]
os.system(command)

If there is anything in <table> you don't like, maybe you could use reset file?

or

if you need this for layout of the page check out the cssplay layout examples for designing websites without tables.

date_default_timezone_set('Australia/Melbourne');   
$time = date("Y-m-d H:i:s", time()); 

You can use [(ngModel)], but you'll need to update your value to [value] otherwise the value is evaluating as a string. It would look like this:

<label>This rule is true if:</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="true" [(ngModel)]="rule.mode">
</label>
<label class="form-check-inline">
    <input class="form-check-input" type="radio" name="mode" [value]="false" [(ngModel)]="rule.mode">
</label>

If rule.mode is true, then that radio is selected. If it's false, then the other.

The difference really comes down to the value. value="true" really evaluates to the string 'true', whereas [value]="true" evaluates to the boolean true.

To reference images in public there are two ways I know how to do it straight forward. One is like above from Homam Bahrani.

using

    <img src={process.env.PUBLIC_URL + '/yourPathHere.jpg'} /> 

And since this works you really don't need anything else but, this also works...

    <img src={window.location.origin + '/yourPathHere.jpg'} />

You can't do it through jQuery alone; you'll need a combination of Ajax (which you can do with jQuery) and a PHP back-end. A very simple version might look like this:

HTML:

<img class="foo" src="img.jpg" />
<img class="foo" src="img2.jpg" />
<img class="foo" src="img3.jpg" />

Javascript:

$("img.foo").onclick(function()
{
    // Get the src of the image
    var src = $(this).attr("src");

    // Send Ajax request to backend.php, with src set as "img" in the POST data
    $.post("/backend.php", {"img": src});
});

PHP (backend.php):

<?php
    // do any authentication first, then add POST variable to session
    $_SESSION['imgsrc'] = $_POST['img'];
?>

I read all the comments and thought that GitHub made it too difficult for normal user to create GitHub pages until I visited GitHub theme Page where its clearly mentioned that there is a section of "GitHub Pages" under settings Page of the concerned repo where you can choose the option "use the master branch for GitHub Pages." and voilà!!...checkout that particular repo on https://username.github.io/reponame

My problem was that the file I was referencing from inside my home.html was a .j2 instead of a .html, and when I changed it back jinja could read it.

Stupid error but it might help someone.

I don't think you can!

/home/export/user1 $ sqlplus / 
> @script1.sql
> HOST CD /home/export/user2
> @script2.sql

script2.sql has to be in /home/export/user1.

You either use the full path, or exit the script and start sqlplus again from the right directory.

#!/bin/bash
oraenv .
cd /home/export/user1
sqlplus / @script1.sql
cd /home/export/user2
sqlplus / @script2.sql

(something like that - doing this from memory!)

Had the same problem. The solution is to add a \ at the end of %ANT_HOME%\bin so it became %ANT_HOME%\bin\

Worked for me. (Should be system var)

$alphabet = array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');

Because cron is "stateless", it cannot accurately express "frequencies", only "patterns" which it (apparently) continuously matches against the current time.

Rephrasing your question makes this more obvious: "is it possible to run a cronjob at 00:01am every night except skip nights when it had run within 2 nights?" When cron is comparing the current time to job request time patterns, there's no way cron can know if it ran your job in the past.

(it certainly is possible to write a stateful cron that records past jobs and thus includes patterns for matching against this state, but that's not the standard cron included in most operating systems. Such a system would get complicated by requiring the introduction of the concept of when such patterns "reset". For example, is the pattern reset when the time is changed (i.e. the crontab entry is revised)? Look to your favorite calendar app to see how complicated it can get to express Repeating patterns of scheduled events, and note that they don't have the reset problem because the starting calendar event has a natural "start" a/k/a "reset" date. Try rescheduling an every-other-week recurring calendar event to postpone by a week, over christmas for example. Usually you have to terminate that recurring event and restart a completely new one; this illustrates the limited expressivity of how even complicated calendar apps represent repeating patterns. And of course Calendars have a lot of state-- each individual event can be deleted or rescheduled independently [in most calendar apps]).

Further, you probably want to do your job every 3rd night if successful, but if the last one failed, to try again immediately, perhaps the next night (not wait 3 more days) or even sooner, like an hour later (but stop retrying upon morning's arrival). Clearly, cron couldn't possibly know if your job succeeded and the pattern can't also express an alternate more frequent "retry" schedule.

ANYWAY-- You can do what you want yourself. Write a script, tell cron to run it nightly at 00:01am. This script could check the timestamp of something* which records the "last run", and if it was >3 days ago**, perform the job and reset the "last run" timestamp.

(*that timestamped indicator is a bit of persisted state which you can manipulate and examine, but which cron cannot)

**be careful with time arithmetic if you're using human-readable clock time-- twice a year, some days have 23 or 25 hours in their day, and 02:00-02:59 occurs twice in one day or not at all. Use UTC to avoid this.

No, they are identical.

default(), for any value type (DateTime is a value type) will always call the parameterless constructor.

DECLARE @search VARCHAR(10);
SET @search = 'Cat';

WITH T(C)
AS
(
SELECT 'Cat, Dog, Sparrow, Trout, Cow, Seahorse'
)
SELECT *
FROM T 
WHERE ', ' + C + ',' LIKE '%, ' + @search + ',%'

This will of course require a full table scan for every search.

As others have mentioned, use triple quotes ”””abc””” for multiline strings. Also, you can do this without having to call close() using the with keyword. For example:

# HTML String
html = """
<table border=1>
     <tr>
       <th>Number</th>
       <th>Square</th>
     </tr>
     <indent>
     <% for i in range(10): %>
       <tr>
         <td><%= i %></td>
         <td><%= i**2 %></td>
       </tr>
     </indent>
</table>
"""

# Write HTML String to file.html
with open("file.html", "w") as file:
    file.write(html)

See https://stackoverflow.com/a/11783672/2206251 for more details on the with keyword in Python.

September 2018 (updated February 2019)

It seems that regexp /\p{L}/u for match letters (as unicode categories)

• works on Chrome 68.0.3440.106 and Safari 11.1.2 (13605.3.8)
• NOT working on Firefox 65.0 :(

Here is a working example

In below field you should be able to to type letters but not numbers<br>_x000D_
<input type="text" name="field" onkeydown="return /\p{L}/u.test(event.key)" >

I report this bug here.

Update

After over 2 years according to: 1500035 > 1361876 > 1634135 finally this bug is fixed and will be available in Firefox v.78+

In the recent go versions from 1.14 onwards, we have to do go mod vendor before building or running, since by default go appends -mod=vendor to the go commands. So after doing go mod vendor, if we try to build, we won't face this issue.

You could also do something as follow

public enum DAY {MON, TUES, WED, THU, FRI, SAT, SUN};
EnumSet.allOf(DAY.class).stream().map(e -> e.name()).collect(Collectors.toList())

or

EnumSet.allOf(DAY.class).stream().map(DAY::name).collect(Collectors.toList())

The main reason why I stumbled across this question is that I wanted to write a generic validator that validates whether a given string enum name is valid for a given enum type (Sharing in case anyone finds useful).

For the validation, I had to use Apache's EnumUtils library since the type of enum is not known at compile time.

@SuppressWarnings({ "unchecked", "rawtypes" })
public static void isValidEnumsValid(Class clazz, Set<String> enumNames) {
    Set<String> notAllowedNames = enumNames.stream()
            .filter(enumName -> !EnumUtils.isValidEnum(clazz, enumName))
            .collect(Collectors.toSet());

    if (notAllowedNames.size() > 0) {
        String validEnumNames = (String) EnumUtils.getEnumMap(clazz).keySet().stream()
            .collect(Collectors.joining(", "));

        throw new IllegalArgumentException("The requested values '" + notAllowedNames.stream()
                .collect(Collectors.joining(",")) + "' are not valid. Please select one more (case-sensitive) "
                + "of the following : " + validEnumNames);
    }
}

I was too lazy to write an enum annotation validator as shown in here https://stackoverflow.com/a/51109419/1225551

Approach: calculate keys to remove, mutate dict

Let's call keys the list/iterator of keys that you are given to remove. I'd do this:

keys_to_remove = set(keys).intersection(set(mydict.keys()))
for key in keys_to_remove:
    del mydict[key]

You calculate up front all the affected items and operate on them.

Approach: calculate keys to keep, make new dict with those keys

I prefer to create a new dictionary over mutating an existing one, so I would probably also consider this:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: v for k, v in mydict.iteritems() if k in keys_to_keep}

or:

keys_to_keep = set(mydict.keys()) - set(keys)
new_dict = {k: mydict[k] for k in keys_to_keep}

Broken pipe means you wrote to a connection that is already closed by the other end.

isConnected() does not detect this condition. Only a write does.

is it wise to always call SocketChannel.isConnected() before attempting a SocketChannel.write()

It is pointless. The socket itself is connected. You connected it. What may not be connected is the connection itself, and you can only determine that by trying it.

You could have searched just for whereIn function in the core to see that. Here you are. This must answer all your questions

/**
 * Add a "where in" clause to the query.
 *
 * @param  string  $column
 * @param  mixed   $values
 * @param  string  $boolean
 * @param  bool    $not
 * @return \Illuminate\Database\Query\Builder|static
 */
public function whereIn($column, $values, $boolean = 'and', $not = false)
{
    $type = $not ? 'NotIn' : 'In';

    // If the value of the where in clause is actually a Closure, we will assume that
    // the developer is using a full sub-select for this "in" statement, and will
    // execute those Closures, then we can re-construct the entire sub-selects.
    if ($values instanceof Closure)
    {
        return $this->whereInSub($column, $values, $boolean, $not);
    }

    $this->wheres[] = compact('type', 'column', 'values', 'boolean');

    $this->bindings = array_merge($this->bindings, $values);

    return $this;
}

Look that it has a third boolean param. Good luck.

You can create a custom label with name UnderlinedLabel and edit drawRect function.

#import "UnderlinedLabel.h"

@implementation UnderlinedLabel

- (void)drawRect:(CGRect)rect
{
   NSString *normalTex = self.text;
   NSDictionary *underlineAttribute = @{NSUnderlineStyleAttributeName: @(NSUnderlineStyleSingle)};
   self.attributedText = [[NSAttributedString alloc] initWithString:normalTex
                                                      attributes:underlineAttribute];

   [super drawRect:rect];
}

Answer is adding to @Sebas' answer - setting the collation of my local environment. Do not try this on production.

ALTER DATABASE databasename CHARACTER SET utf8 COLLATE utf8_unicode_ci;

ALTER TABLE tablename CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;

Source of this solution

As shaishab roy says, in the cheat sheet you can find the answer.

But in his answer, the given response was :

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

For some reasons, it doesn't works on my side, so I tried instead :

{path: '/**', redirectTo: ['NotFound']}

and it works. Be careful and don't forget that you need to put it at the end, or else you will often have the 404 error page ;).

Plain JavaScript escaping example:

function escapeHtml(text) {
    var div = document.createElement('div');
    div.innerText = text;
    return div.innerHTML;
}

escapeHtml("<script>alert('hi!');</script>")
// "&lt;script&gt;alert('hi!');&lt;/script&gt;"

Try using this tool,which is just a simple js script https://github.com/shashwatsahai/CSSExtractor/ This tool helps in getting the CSS from a specific page listing all sources for active styles and save it to a JSON with source as key and rules as value. It loads all the CSS from the href links and tells all the styles applied from them You can modify the code to save all css into a .css file. Thereby combining all your css.

You can make your object comparable:

public static class MyObject implements Comparable<MyObject> {

  private Date dateTime;

  public Date getDateTime() {
    return dateTime;
  }

  public void setDateTime(Date datetime) {
    this.dateTime = datetime;
  }

  @Override
  public int compareTo(MyObject o) {
    return getDateTime().compareTo(o.getDateTime());
  }
}

And then you sort it by calling:

Collections.sort(myList);

However sometimes you don't want to change your model, like when you want to sort on several different properties. In that case, you can create comparator on the fly:

Collections.sort(myList, new Comparator<MyObject>() {
  public int compare(MyObject o1, MyObject o2) {
      return o1.getDateTime().compareTo(o2.getDateTime());
  }
});

However, the above works only if you're certain that dateTime is not null at the time of comparison. It's wise to handle null as well to avoid NullPointerExceptions:

public static class MyObject implements Comparable<MyObject> {

  private Date dateTime;

  public Date getDateTime() {
    return dateTime;
  }

  public void setDateTime(Date datetime) {
    this.dateTime = datetime;
  }

  @Override
  public int compareTo(MyObject o) {
    if (getDateTime() == null || o.getDateTime() == null)
      return 0;
    return getDateTime().compareTo(o.getDateTime());
  }
}

Or in the second example:

Collections.sort(myList, new Comparator<MyObject>() {
  public int compare(MyObject o1, MyObject o2) {
      if (o1.getDateTime() == null || o2.getDateTime() == null)
        return 0;
      return o1.getDateTime().compareTo(o2.getDateTime());
  }
});

ALLOW-FROM is not supported in Chrome or Safari. See MDN article: https://developer.mozilla.org/en-US/docs/Web/HTTP/X-Frame-Options

You are already doing the work to make a custom header and send it with the correct data, can you not just exclude the header when you detect it is from a valid partner and add DENY to every other request? I don't see the benefit of AllowFrom when you are already dynamically building the logic up?

If you pass only vectors to cbind() it creates a matrix, not a dataframe. Read ?data.frame.

Try the following configuration:

log4j.rootLogger=TRACE, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.debugLog=org.apache.log4j.FileAppender
log4j.appender.debugLog.File=logs/debug.log
log4j.appender.debugLog.layout=org.apache.log4j.PatternLayout
log4j.appender.debugLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.appender.reportsLog=org.apache.log4j.FileAppender
log4j.appender.reportsLog.File=logs/reports.log
log4j.appender.reportsLog.layout=org.apache.log4j.PatternLayout
log4j.appender.reportsLog.layout.ConversionPattern=%d [%24F:%t:%L] - %m%n

log4j.category.debugLogger=TRACE, debugLog
log4j.additivity.debugLogger=false

log4j.category.reportsLogger=DEBUG, reportsLog
log4j.additivity.reportsLogger=false

Then configure the loggers in the Java code accordingly:

static final Logger debugLog = Logger.getLogger("debugLogger");
static final Logger resultLog = Logger.getLogger("reportsLogger");

Do you want output to go to stdout? If not, change the first line of log4j.properties to:

log4j.rootLogger=OFF

and get rid of the stdout lines.

$ sudo apt install python3-sklearn 

then try your command. hope it will work

There is 3 rapid examples with pure CSS and without javascript where the content appears "on click", with a "maintained click" and a third "onhover" (all only tested in Chrome). Sorry for the up of this post but this question are the first seo result and maybe my contribution can help beginner like me

I think (not tested) but the advantage of argument "content" that you can add great icon like from Font Awesome (its \f-Code) or an hexadecimal icon in place of the text "Hide" and "Show" to internationalize the trick.

In Windows debug.keystore file is localtes at C:\Users\%Username%\.android folder. This file is created when you install your android SDK and is valid only for a year. After this perod you will start getting this error Error getting final archive: Debug certificate expired on xx/xx/xxxx.

To remove this error simply delete the file and run the program again. In my Eclipse I have enabled Project->Build Automatically so it directly worked but in case you have disabled it you will need to clean the project Project->Clean.. select your project and press ok. Then you will need to build it manually. 3rd click on your project and select Build project.(Note - You will only see this option if you have diabled Build Automatically feature in your Projects Menu)

$('#userid').change(function(){
  //fire your ajax call  
});

$('#userid').val(10).change();

There are no multi-dimensional arrays in Java, there are, however, arrays of arrays.

Just make an array of however large you want, then for each element make another array however large you want that one to be.

int array[][];

array = new int[10][];

array[0] = new int[9];
array[1] = new int[8];
array[2] = new int[7];
array[3] = new int[6];
array[4] = new int[5];
array[5] = new int[4];
array[6] = new int[3];
array[7] = new int[2];
array[8] = new int[1];
array[9] = new int[0];

Alternatively:

List<Integer>[] array;

array = new List<Integer>[10];

// of you can do "new ArrayList<Integer>(the desired size);" for all of the following
array[0] = new ArrayList<Integer>();
array[1] = new ArrayList<Integer>();
array[2] = new ArrayList<Integer>();
array[3] = new ArrayList<Integer>();
array[4] = new ArrayList<Integer>();
array[5] = new ArrayList<Integer>();
array[6] = new ArrayList<Integer>();
array[7] = new ArrayList<Integer>();
array[8] = new ArrayList<Integer>();
array[9] = new ArrayList<Integer>();

The main concept of partial view is returning the HTML code rather than going to the partial view it self.

[HttpGet]
public ActionResult Calendar(int year)
{
    var dates = new List<DateTime>() { /* values based on year */ };
    HolidayViewModel model = new HolidayViewModel {
        Dates = dates
    };
    return PartialView("HolidayPartialView", model);
}

this action return the HTML code of the partial view ("HolidayPartialView").

To refresh partial view replace the existing item with the new filtered item using the jQuery below.

$.ajax({
                url: "/Holiday/Calendar",
                type: "GET",
                data: { year: ((val * 1) + 1) }
            })
            .done(function(partialViewResult) {
                $("#refTable").html(partialViewResult);
            });

If you have an interface in your controller

public myController(IXInterface Xinstance){}

You must register them to Dependency Injection container.

container.Bind<IXInterface>().To<XClass>().InRequestScope();

Look here http://docs.oracle.com/javase/6/docs/api/java/awt/Font.html#deriveFont%28float%29

JComponent has a setFont() method. You will control the font there, not on the String.

Such as

JButton b = new JButton();
b.setFont(b.getFont().deriveFont(18.0f));

Both find() and children() methods are used to filter the child of the matched elements, except the former is travels any level down, the latter is travels a single level down.

To simplify:

1. find() – search through the matched elements’ child, grandchild, great-grandchild... all levels down.
2. children() – search through the matched elements’ child only (single level down).

Add your start class in your pom:

<properties>
    <!-- The main class to start by executing java -jar -->
    <start-class>com.mycorp.starter.HelloWorldApplication</start-class>
</properties>

or

<build>
<plugins>
    <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>             
        <configuration>    
            <mainClass>com.mycorp.starter.HelloWorldApplication</mainClass>
        </configuration>
    </plugin>
</plugins>
</build>

You could also use File.Copy to copy and File.Move to rename it afterwords.

// Copy the file (specify true or false to overwrite or not overwrite the destination file if it exists.
File.Copy(mySourceFileAndPath, myDestinationFileAndPath, [true | false]);

// EDIT: as "astander" notes correctly, this step is not necessary, as File.Copy can rename already...
//       However, this code could be adapted to rename the original file after copying
// Rename the file if the destination file doesn't exist. Throw exception otherwise
//if (!File.Exists(myRenamedDestinationFileAndPath))
//    File.Move(myDestinationFileAndPath, myRenamedDestinationFileAndPath);
//else
//    throw new IOException("Failed to rename file after copying, because destination file exists!");

EDIT
Commented out the "rename" code, because File.Copy can already copy and rename in one step, as astander noted correctly in the comments.

However, the rename code could be adapted if the OP desired to rename the source file after it has been copied to a new location.

I got this in my browser when I changed from using http://localhost to http://145.900.50.20 (where 145.900.50.20 is my local IP address) and then changed back to localhost -- it was necessary to stay with the IP address once I had changed to that once

In this example of a rc.local script I use io redirection at the very first line of execution to my own log file:

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

exec 2> /tmp/rc.local.log  # send stderr from rc.local to a log file
exec 1>&2                      # send stdout to the same log file
set -x                         # tell sh to display commands before execution

/opt/stuff/somefancy.error.script.sh

exit 0

All you need to do is specify "type": "module" in package.json.

clear pictureBox in c# winform Application Simple way to clear pictureBox in c# winform Application

If you're on Debian:

1) remove all installed package through Virtualbox Guest Additions ISO file:

sh /media/cdrom/VBoxLinuxAdditions.run uninstall

2) install Virtualbox packages:

apt-get install build-essential module-assistant virtualbox-guest-dkms virtualbox-guest-utils

Note that even with modprobe vboxsf returning nothing (so the module is correctly loaded), the vboxsf.so will call an executable named mount.vboxsf, which is provided by virtualbox-guest-utils. Ignoring this one will prevent you from understanding the real cause of the error.

strace mount /your-directory was a great help (No such file or directory on /sbin/mount.vboxsf).

Always remember to be careful with nulls in pl/sql conditional clauses as null is never greater, smaller, equal or unequal to anything. Best way to avoid them is to use nvl.

For example

declare
  i integer;
begin
  if i <> 1 then
    i:=1;
    foobar();
  end if;
end;
/

Never goes inside the if clause.

These would work.

if 1<>nvl(i,1) then
if i<> 1 or i is null then

You could use the struct Python built-in library:

Encode:

import struct

i = -6884376
print('{0:b}'.format(i))

packed = struct.pack('>l', i)  # Packing a long number.
unpacked = struct.unpack('>L', packed)[0]  # Unpacking a packed long number to unsigned long
print(unpacked)
print('{0:b}'.format(unpacked))

Out:

-11010010000110000011000
4288082920
11111111100101101111001111101000

Decode:

dec_pack = struct.pack('>L', unpacked)  # Packing an unsigned long number.
dec_unpack = struct.unpack('>l', dec_pack)[0]  # Unpacking a packed unsigned long number to long (revert action).
print(dec_unpack)

Out:

-6884376

[NOTE]:

• > is BigEndian operation.
• l is long.
• L is unsigned long.
• In amd64 architecture int and long are 32bit, So you could use i and I instead of l and L respectively.

The case values are just codeless "goto" points that can share the same entry point:

case text1:
case text4: {
//Do something
break;
}

Note that the braces are redundant.

You can use Will Dean's suggestion [#define arraysize(ar) (sizeof(ar) / sizeof(ar[0]))] to replace the magic number 3 here with arraysize(str_array) -- although I remember there being some special case in which that particular version of arraysize might do Something Bad (sorry I can't remember the details immediately). But it very often works correctly.

The case where it doesn't work is when the "array" is really just a pointer, not an actual array. Also, because of the way arrays are passed to functions (converted to a pointer to the first element), it doesn't work across function calls even if the signature looks like an array — some_function(string parameter[]) is really some_function(string *parameter).

If you want to use 'lengthMenu' together with buttons(copy, export), you have to use this option dom: 'lBfrtip'. Here https://datatables.net/reference/option/dom you can find meaning of each symbol. For example, if you will use like this 'Bfrtip', lengthMenu will not appears.

Try this in fragment :

layoutManager = new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false);

mRecyclerView.setLayoutManager(layoutManager);

Warning create_function() has been DEPRECATED as of PHP 7.2.0. Relying on this function is highly discouraged.

Builtin loops in PHP are faster then interpreted loops, so it actually makes sense to make this one a one-liner:

$result = array();
array_walk($cats, create_function('$value, $key, &$result', '$result[] = $value->id;'), $result)

Cursor itself is an iterator (like WHILE). By saying iterator I mean a way to traverse the record set (aka a set of selected data rows) and do operations on it while traversing. Operations could be INSERT or DELETE for example. Hence you can use it for data retrieval for example. Cursor works with the rows of the result set sequentially - row by row. A cursor can be viewed as a pointer to one row in a set of rows and can only reference one row at a time, but can move to other rows of the result set as needed.

This link can has a clear explanation of its syntax and contains additional information plus examples.

Cursors can be used in Sprocs too. They are a shortcut that allow you to use one query to do a task instead of several queries. However, cursors recognize scope and are considered undefined out of the scope of the sproc and their operations execute within a single procedure. A stored procedure cannot open, fetch, or close a cursor that was not declared in the procedure.

To disable the phone parsing appearance for specific elements, this CSS seems to do the trick:

.element { pointer-events: none; }
.element > a { text-decoration:none; color:inherit; }

The first rule disables the click, the second takes care of the styling.

After spending a considerable amount of time trying all the options, the only way I was able to get an app using AppCompat v7 to change the overflow menu background was using the itemBackground attribute:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    ...
    <item name="android:itemBackground">@color/overflow_background</item>
    ...
</style>

Tested from API 4.2 to 5.0.

I have recently implemented the receipt printing simply by pressing a button on a web page, without having to enter the printer options. I have done it using EPSON javascript SDK for ePOS. I have test it on EPSON TM-m30 receipt printer.

Here is the sample code.

var printer = null;
var ePosDev = null;

function InitMyPrinter() {
    console.log("Init Printer");

    var printerPort = 8008;
    var printerAddress = "192.168.198.168";
    if (isSSL) {
        printerPort = 8043;
    }
    ePosDev = new epson.ePOSDevice();
    ePosDev.connect(printerAddress, printerPort, cbConnect);
}

//Printing
function cbConnect(data) {
    if (data == 'OK' || data == 'SSL_CONNECT_OK') {
        ePosDev.createDevice('local_printer', ePosDev.DEVICE_TYPE_PRINTER,
            {'crypto': false, 'buffer': false}, cbCreateDevice_printer);
    } else {
        console.log(data);
    }
}

function cbCreateDevice_printer(devobj, retcode) {
    if (retcode == 'OK') {
        printer = devobj;
        printer.timeout = 60000;
        printer.onreceive = function (res) { //alert(res.success);
            console.log("Printer Object Created");

        };
        printer.oncoveropen = function () { //alert('coveropen');
            console.log("Printer Cover Open");

        };
    } else {
        console.log(retcode);
        isRegPrintConnected = false;
    }
}

function print(salePrintObj) {
    debugger;
    if (isRegPrintConnected == false
        || printer == null) {
        return;
    }
    console.log("Printing Started");


    printer.addLayout(printer.LAYOUT_RECEIPT, 800, 0, 0, 0, 35, 0);
    printer.addTextAlign(printer.ALIGN_CENTER);
    printer.addTextSmooth(true);
    printer.addText('\n');
    printer.addText('\n');

    printer.addTextDouble(true, true);
    printer.addText(CompanyName + '\n');

    printer.addTextDouble(false, false);
    printer.addText(CompanyHeader + '\n');
    printer.addText('\n');

    printer.addTextAlign(printer.ALIGN_LEFT);
    printer.addText('DATE: ' + currentDate + '\t\t');

    printer.addTextAlign(printer.ALIGN_RIGHT);
    printer.addText('TIME: ' + currentTime + '\n');

    printer.addTextAlign(printer.ALIGN_LEFT);

    printer.addTextAlign(printer.ALIGN_RIGHT);
    printer.addText('REGISTER: ' + RegisterName + '\n');
    printer.addTextAlign(printer.ALIGN_LEFT);
    printer.addText('SALE # ' + SaleNumber + '\n');

    printer.addTextAlign(printer.ALIGN_CENTER);
    printer.addTextStyle(false, false, true, printer.COLOR_1);
    printer.addTextStyle(false, false, false, printer.COLOR_1);
    printer.addTextDouble(false, true);
    printer.addText('* SALE RECEIPT *\n');
    printer.addTextDouble(false, false);

opening a file using fopen
before we can read(or write) information from (to) a file on a disk we must open the file. to open the file we have called the function fopen.

1.firstly it searches on the disk the file to be opened.
2.then it loads the file from the disk into a place in memory called buffer.
3.it sets up a character pointer that points to the first character of the buffer.

this the way of behaviour of fopen function
there are some causes while buffering process,it may timedout. so while comparing fopen(high level i/o) to open (low level i/o) system call , and it is a faster more appropriate than fopen.

I had this issue. The problem was I had a font-family CSS style with !important overriding the fontawesome font.

The solution which ultimately worked best for my organization is detailed below, it just adds a check on render for the sysadmin route and redirects the user to a different main path of the application if they are not allowed to be in the page.

SysAdminRoute.tsx

import React from 'react';
import { Route, Redirect, RouteProps } from 'react-router-dom';
import AuthService from '../services/AuthService';
import { appSectionPageUrls } from './appSectionPageUrls';
interface IProps extends RouteProps {}
export const SysAdminRoute = (props: IProps) => {
    var authService = new AuthService();
    if (!authService.getIsSysAdmin()) { //example
        authService.logout();
        return (<Redirect to={{
            pathname: appSectionPageUrls.site //front-facing
        }} />);
    }
    return (<Route {...props} />);
}

There are 3 main routes for our implementation, the public facing /site, the logged in client /app, and sys admin tools at /sysadmin. You get redirected based on your 'authiness' and this is the page at /sysadmin.

SysAdminNav.tsx

<Switch>
    <SysAdminRoute exact path={sysadminUrls.someSysAdminUrl} render={() => <SomeSysAdminUrl/> } />
    //etc
</Switch>

i would suggest the following way:

@PropertySource(ignoreResourceNotFound = true, value = "classpath:otherprops.properties")
@Controller
public class ClassA {
    @Value("${myName}")
    private String name;

    @RequestMapping(value = "/xyz")
    @ResponseBody
    public void getName(){
        System.out.println(name);
    }
}

Here your new properties file name is "otherprops.properties" and the property name is "myName". This is the simplest implementation to access properties file in spring boot version 1.5.8.

To set the summary of a ListPreference to the value selected in a dialog you could use this code:

package yourpackage;

import android.content.Context;
import android.util.AttributeSet;

public class ListPreference extends android.preference.ListPreference {

    public ListPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    protected void onDialogClosed(boolean positiveResult) {
        super.onDialogClosed(positiveResult);
        if (positiveResult) setSummary(getEntry());
    }

    protected void onSetInitialValue(boolean restoreValue, Object defaultValue) {
        super.onSetInitialValue(restoreValue, defaultValue);
        setSummary(getEntry());
    }
}

and reference the yourpackage.ListPreference object in your preferences.xml remembering to specify there your android:defaultValue as this triggers the call to onSetInitialValue().

If you want you can then modify the text before calling setSummary() to whatever suits your application.

This is very simple to do:

import matplotlib.pyplot as plt

plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.plot(<X AXIS VALUES HERE>, <Y AXIS VALUES HERE>, 'line type', label='label here')
plt.legend(loc='best')
plt.show()

You can keep adding plt.plot as many times as you like. As for line type, you need to first specify the color. So for blue, it's b. And for a normal line it's -. An example would be:

plt.plot(total_lengths, sort_times_heap, 'b-', label="Heap")

Okay I fixed this thing. Had to first convert the projects to Maven Projects, then remove them from the Eclipse workspace, and then re-import them.

You can use as follows

public ActionResult NewWindow()
{
    return Content("<script>window.open('{url}','_blank')</script>");
}

Sure

write-host ($obj | Select -ExpandProperty "SomeProp")

Or for that matter:

$obj."SomeProp"

You're in replace mode. Press the Insert key on your keyboard to switch back to insert mode. Many applications that handle text have this in common.

as far as i know, --hard will discards uncommitted changes. Since these aren't tracked by git. but you can undo the discarded commit.

$ git reflog

will lists:

b0d059c HEAD@{0}: reset: moving to HEAD~1
4bac331 HEAD@{1}: commit: added level introduction....
....

where 4bac331 is the discarded commit.

Now just move the head to that commit::

$ git reset --hard 4bac331

On button click you can try the following.

protected void button1_Click(object sender, EventArgs e)
{
     Response.Redirect("~/Admin/Admin.aspx");
}

And on PageLoad you can check whether the loading is coming from that button then increase the count.

       protected void Page_Load(object sender, EventArgs e)

This can be initiated however you want. timeout is the method i used to keep it on the top of the hour.

I had the need for every hour to begin a code block on the hour. So this would start at server startup and run the interval hourly. Basicaly the initial run is to begin the interval within the same minute. So in a second from init, run immediately then on every 5 seconds.

var interval = 1000;
var timing =function(){
    var timer = setInterval(function(){
        console.log(interval);
        if(interval == 1000){ /*interval you dont want anymore or increment/decrement */
            interval = 3600000; /* Increment you do want for timer */
            clearInterval(timer);
            timing();
        }
    },interval);
}
timing();

Alternately if you wanted to just have something happen at start and then forever at a specific interval you could just call it at the same time as the setInterval. For example:

var this = function(){
 //do
}
setInterval(function(){
  this()
},3600000)
this()

Here we have this run the first time and then every hour.

If you broke the tree but didn't commit the code, you can use git reset, and if you just want to restore one file, you can use git checkout.

If you broke the tree and committed the code, you can use git revert HEAD.

http://book.git-scm.com/4_undoing_in_git_-_reset,_checkout_and_revert.html

Why do you want to use sprintf for string concatenation when there are methods intended specifically for what you need such as strcat and strncat?

You can use request.getQueryString(),if the query string is like

username=james&password=pwd

To get name you can do this

request.getParameter("username"); 

AssertionError is an Unchecked Exception which rises explicitly by programmer or by API Developer to indicate that assert statement fails.

assert(x>10);

Output:

AssertionError

If x is not greater than 10 then you will get runtime exception saying AssertionError.

Since git is a distributed VCS, your local repository contains all of the information. No downloading is necessary; you just need to extract the content you want from the repo at your fingertips.

If you haven't committed the deletion, just check out the files from your current commit:

git checkout HEAD <path>

If you have committed the deletion, you need to check out the files from a commit that has them. Presumably it would be the previous commit:

git checkout HEAD^ <path>

but if it's n commits ago, use HEAD~n, or simply fire up gitk, find the SHA1 of the appropriate commit, and paste it in.

If you're using Gated builds, when a build is triggered, it creates a shelveset of your workspace that is submitted for build. If the build fails, the shelveset is rejected. If the build is successful, a changeset is created and committed to TFS. In either event, the person doing that check-in/build will have to reconcile the workspace, which is as simple as performing a Get Latest.

Remove directory from git and local

You could checkout 'master' with both directories;

git rm -r one-of-the-directories // This deletes from filesystem
git commit . -m "Remove duplicated directory"
git push origin <your-git-branch> (typically 'master', but not always)

Remove directory from git but NOT local

As mentioned in the comments, what you usually want to do is remove this directory from git but not delete it entirely from the filesystem (local)

In that case use:

git rm -r --cached myFolder

If you want to get rid of the "black bars" and do it like YouTube does it, you can use:

https://i.ytimg.com/vi_webp/<video id>/mqdefault.webp

And if you can't use the .webp file extension you can do it like this:

https://i.ytimg.com/vi/<video id>/mqdefault.jpg

Also, if you need the unscaled version, use maxresdefault instead of mqdefault.

Note: I'm not sure about the aspect ratio if you're planning to use maxresdefault.

The TensorFlow Convolution example gives an overview about the difference between SAME and VALID :

• For the SAME padding, the output height and width are computed as:

  out_height = ceil(float(in_height) / float(strides[1]))
  out_width  = ceil(float(in_width) / float(strides[2]))
  

And

• For the VALID padding, the output height and width are computed as:

  out_height = ceil(float(in_height - filter_height + 1) / float(strides[1]))
  out_width  = ceil(float(in_width - filter_width + 1) / float(strides[2]))
  

It might be the standard error. You can redirect it:

... > out.txt 2>&1

Use the error handler like this:

$('#image_id').error(function() {
  alert('Image does not exist !!');
});

If the image cannot be loaded (for example, because it is not present at the supplied URL), the alert is displayed:

Update:

I think using:

$.ajax({url:'somefile.dat',type:'HEAD',error:do_something});

would be enough to check for a 404.

More Readings:

• http://www.jibbering.com/2002/4/httprequest.html
• http://www.ibm.com/developerworks/web/library/wa-ajaxintro3/

Update 2:

Your code should be like this:

$(this).error(function() {
  alert('Image does not exist !!');
});

No need for these lines and that won't check if the remote file exists anyway:

var imgcheck = imgsrc.width;    

if (imgcheck==0) {
  alert("You have a zero size image");
} else { 
  //execute the rest of code here 
}

you can use this:

It depends on which language you use.

In Java/Java EE:

• Jetty 7.0 supports it (very easy to use) V 7.5 supports RFC6455 - Jetty 9.1 supports javax.websocket / JSR 356)

• Caucho Resin 4.0.2 (not yet tried) V 4.0.25 supports RFC6455
• Tomcat 7.0.27 now supports it V 7.0.28 supports RFC6455
• Tomcat 8.x has native support for websockets RFC6455 and is JSR 356 compliant
• JSR 356 included in Java EE 7 will define the Java API for WebSocket, but is not yet stable and complete. See Arun GUPTA's article WebSocket and Java EE 7 - Getting Ready for JSR 356 (TOTD #181) and QCon presentation (from 00:37:36 to 00:46:53) for more information on progress.

I'm able to exclude multiple directories using the below config (comma separated folder paths):

sonar.exclusions=system/**, test/**, application/third_party/**, application/logs/**

And while running the sonar runner I got the following in the log:

Excluded sources: 
  system/**
  test/**
  application/third_party/**
  application/logs/**

\D is a non-digit, and so then \D* is any number of non-digits in a row. So your whole string should match ^\D*$.

Check on http://rubular.com/r/AoWBmrbUkN it works perfectly.

You can also try on http://regexpal.com/ OR http://www.regextester.com/

The approximate conversions are:

• Latitude: 1 deg = 110.574 km
• Longitude: 1 deg = 111.320*cos(latitude) km

This doesn't fully correct for the Earth's polar flattening - for that you'd probably want a more complicated formula using the WGS84 reference ellipsoid (the model used for GPS). But the error is probably negligible for your purposes.

Source: http://en.wikipedia.org/wiki/Latitude

Caution: Be aware that latlong coordinates are expressed in degrees, while the cos function in most (all?) languages typically accepts radians, therefore a degree to radians conversion is needed.

Sadly, Mark Rushakoff's answer (now deleted - it referenced the code from here) does not seem to work correctly when adapted to:

source=/home/part2/part3/part4
target=/work/proj1/proj2

The thinking outlined in the commentary can be refined to make it work correctly for most cases. I'm about to assume that the script takes a source argument (where you are) and a target argument (where you want to get to), and that either both are absolute pathnames or both are relative. If one is absolute and the other relative, the easiest thing is to prefix the relative name with the current working directory - but the code below does not do that.

Beware

The code below is close to working correctly, but is not quite right.

1. There is the problem addressed in the comments from Dennis Williamson.
2. There is also a problem that this purely textual processing of pathnames and you can be seriously messed up by weird symlinks.
3. The code does not handle stray 'dots' in paths like 'xyz/./pqr'.
4. The code does not handle stray 'double dots' in paths like 'xyz/../pqr'.
5. Trivially: the code does not remove leading './' from paths.

Dennis's code is better because it fixes 1 and 5 - but has the same issues 2, 3, 4. Use Dennis's code (and up-vote it ahead of this) because of that.

(NB: POSIX provides a system call realpath() that resolves pathnames so that there are no symlinks left in them. Applying that to the input names, and then using Dennis's code would give the correct answer each time. It is trivial to write the C code that wraps realpath() - I've done it - but I don't know of a standard utility that does so.)

For this, I find Perl easier to use than shell, though bash has decent support for arrays and could probably do this too - exercise for the reader. So, given two compatible names, split them each into components:

• Set the relative path to empty.
• While the components are the same, skip to the next.
• When corresponding components are different or there are no more components for one path:
• If there are no remaining source components and the relative path is empty, add "." to the start.
• For each remaining source component, prefix the relative path with "../".
• If there are no remaining target components and the relative path is empty, add "." to the start.
• For each remaining target component, add the component to the end of the path after a slash.

Thus:

#!/bin/perl -w

use strict;

# Should fettle the arguments if one is absolute and one relative:
# Oops - missing functionality!

# Split!
my(@source) = split '/', $ARGV[0];
my(@target) = split '/', $ARGV[1];

my $count = scalar(@source);
   $count = scalar(@target) if (scalar(@target) < $count);
my $relpath = "";

my $i;
for ($i = 0; $i < $count; $i++)
{
    last if $source[$i] ne $target[$i];
}

$relpath = "." if ($i >= scalar(@source) && $relpath eq "");
for (my $s = $i; $s < scalar(@source); $s++)
{
    $relpath = "../$relpath";
}
$relpath = "." if ($i >= scalar(@target) && $relpath eq "");
for (my $t = $i; $t < scalar(@target); $t++)
{
    $relpath .= "/$target[$t]";
}

# Clean up result (remove double slash, trailing slash, trailing slash-dot).
$relpath =~ s%//%/%;
$relpath =~ s%/$%%;
$relpath =~ s%/\.$%%;

print "source  = $ARGV[0]\n";
print "target  = $ARGV[1]\n";
print "relpath = $relpath\n";

This Perl script works fairly thoroughly on Unix (it does not take into account all the complexities of Windows path names) in the face of weird inputs. It uses the module Cwd and its function realpath to resolve the real path of names that exist, and does a textual analysis for paths that don't exist. In all cases except one, it produces the same output as Dennis's script. The deviant case is:

source   = home/part1/part2
target   = .
relpath1 = ../../..
relpath2 = ../../../.

The two results are equivalent - just not identical. (The output is from a mildly modified version of the test script - the Perl script below simply prints the answer, rather than the inputs and the answer as in the script above.) Now: should I eliminate the non-working answer? Maybe...

Change

I just encountered a similar issue and I found that it is a permission problem. When I copy the database "data", I have to add the permission for "NETWORK SERVICE"

For some instrutions, like ALTER TABLE, this is not possible with MySQL, even with transactions (1 and 2).

Using base-n mini lib, you can do the following:

some_data_t in[] { ... };
constexpr int len = sizeof(in)/sizeof(in[0]);

std::string encoded;
bn::encode_b64(in, in + len, std::back_inserter(encoded));

some_data_t out[len];
bn::decode_b64(encoded.begin(), encoded.end(), out);

The API is generic, iterator-based.

I cheated, but I believe this is the only answer that addresses every requirement. Namely, this avoids the trailing CRLF, provides a place for the other operation to complete in the meantime, and properly redirects to stdout as necessary.

Is this endpoint taking too many time?

Maybe you are using flask without asynchronous support, so every request will block the call. To create async support without make difficult, add the gevent worker.

With gevent, a new call will spawn a new thread, and you app will be able to receive more requests

pip install gevent

Opacity gives you translucency or transparency. See an example Fiddle here.

-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=50)";       /* IE 8 */
filter: alpha(opacity=50);  /* IE 5-7 */
-moz-opacity: 0.5;          /* Netscape */
-khtml-opacity: 0.5;        /* Safari 1.x */
opacity: 0.5;               /* Good browsers */

Note: these are NOT CSS3 properties

I've never used it but there is a JWT implementation on NuGet.

Package: https://nuget.org/packages/JWT

Source: https://github.com/johnsheehan/jwt

.NET 4.0 compatible: https://www.nuget.org/packages/jose-jwt/

You can also go here: https://jwt.io/ and click "libraries".

List<string> values =new list<string>();
foreach(ListItem Item in ChkList.Item)
{
    if(Item.Selected)
    values.Add(item.Value);
}

Try to use always the smallest datatype that you can and index all the fields most used in queries.

Try to avoid server side cursors as much as possible. Always stick to a 'set-based approach' instead of a 'procedural approach' for accessing and manipulating data. Cursors can often be avoided by using SELECT statements instead.

Always use the graphical execution plan in Query Analyzer or SHOWPLAN_TEXT or SHOWPLAN_ALL commands to analyze your queries. Make sure your queries do an "Index seek" instead of an "Index scan" or a "Table scan." A table scan or an index scan is a very bad thing and should be avoided where possible. Choose the right indexes on the right columns. Use the more readable ANSI-Standard Join clauses instead of the old style joins. With ANSI joins, the WHERE clause is used only for filtering data. Where as with older style joins, the WHERE clause handles both the join condition and filtering data.

Do not let your front-end applications query/manipulate the data directly using SELECT or INSERT/UPDATE/DELETE statements. Instead, create stored procedures, and let your applications access these stored procedures. This keeps the data access clean and consistent across all the modules of your application, and at the same time centralizing the business logic within the database.

Speaking about Stored procedures, do not prefix your stored procedure names with "sp_". The prefix sp_ is reserved for system stored procedure that ship with SQL Server. Whenever SQL Server encounters a procedure name starting with sp_, it first tries to locate the procedure in the master database, then it looks for any qualifiers (database, owner) provided, then it tries dbo as the owner. So you can really save time in locating the stored procedure by avoiding the "sp_" prefix.

Avoid dynamic SQL statements as much as possible. Dynamic SQL tends to be slower than static SQL, as SQL Server must generate an execution plan every time at runtime.

When is possible, try to use integrated authentication. It means, forget about the sa and others SQL users, use the microsoft user provisioning infra-structure and keep always your SQL server, up-to-date with all required patches. Microsoft do a good job developing, testing and releasing patches but it's your job to apply it.

Use OUTER APPLY instead of LEFT JOIN:

SELECT u.id, mbg.marker_value 
FROM dps_user u
OUTER APPLY 
    (SELECT TOP 1 m.marker_value, um.profile_id
     FROM dps_usr_markers um (NOLOCK)
         INNER JOIN dps_markers m (NOLOCK) 
             ON m.marker_id= um.marker_id AND 
                m.marker_key = 'moneyBackGuaranteeLength'
     WHERE um.profile_id=u.id 
     ORDER BY m.creation_date
    ) AS MBG
WHERE u.id = 'u162231993';

Unlike JOIN, APPLY allows you to reference the u.id inside the inner query.

I tried the following:

 int index = mViewPager.getCurrentItem();
 List<Fragment> fragments = getSupportFragmentManager().getFragments();
 View rootView = fragments.get(index).getView();

If you are using IntelliJ, just do the following.

1. Close the project
2. (re)Open the project
3. you will see "Import gradle project" message on the right bottom. click.
4. select "Use default gradle wrapper". not "Use local gradle distribution"

That's all.

The problem is caused by the fact that cmbDataSourceExtractor.CancelAsync() is an asynchronous method, the Cancel operation has not yet completed when cmdDataSourceExtractor.RunWorkerAsync(...) exitst. You should wait for cmdDataSourceExtractor to complete before calling RunWorkerAsync again. How to do this is explained in this SO question.

Depends on what you're doing.

For instance:

//bankers' rounding - midpoint goes to nearest even
GetIntPart(2.5) >> 2
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -6

or

//arithmetic rounding - midpoint goes away from zero
GetIntPart(2.5) >> 3
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -7

The default is always the former, which can be a surprise but makes very good sense.

Your explicit cast will do:

int intPart = (int)343564564.5
// intPart will be 343564564

int intPart = (int)343564565.5
// intPart will be 343564566

From the way you've worded the question it sounds like this isn't what you want - you want to floor it every time.

I would do:

Math.Floor(Math.Abs(number));

Also check the size of your decimal - they can be quite big, so you may need to use a long.
