//example
char character;//to be scanned
char merge[2];// this is just temporary array to merge with      
merge[0] = character;
merge[1] = '\0';
//now you have changed it into a string

I liked the answer by @Amc. I found the expression could be condensed further to not use a filter() call (@chaiko apparently also noticed this). Also, prop() is the way to go vs attr() for jQuery v1.6+, see the jQuery documentation for prop() for the official best practices on the subject.

Consider the same input tags from @Paolo Bergantino's answer.

<input type='radio' name='gender' value='Male'>
<input type='radio' name='gender' value='Female'>

The updated one-liner might read something like:

$('input:radio[name="gender"][value="Male"]').prop('checked', true);

I've had a similar error for react-native-youtube & react-native-orientation.

Figured out, that the build.gradle of those Project use compileSdkVersion 23 but the Feature: android:keyboardNavigationCluster was added since api 26 (android 8).

So how to fix?

One way to fix this easily is to edit your /android/build.gradle ( !!! NOT /android/app/build.gradle) and add those code at the bottom of the file.

This allow you to force the SDK and BuildTool-Version your submodules use:

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                compileSdkVersion 27
                buildToolsVersion "27.0.2"
            }
        }
    }
}

Delete the node_modules folder

Then you should run the commands:

npm install --no-bin-links

npm run dev

It's worked on my Laravel 5.5 and Windows.

In javascript you have to use \. to match a dot.

Example

"blah.tests.zibri.org".match('test\\..*')
null

and

"blah.test.zibri.org".match('test\\..*')
["test.zibri.org", index: 5, input: "blah.test.zibri.org", groups: undefined]

"<name> <substring>"[/.*<([^>]*)/,1]
=> "substring"

No need to use scan, if we need only one result.
No need to use Python's match, when we have Ruby's String[regexp,#].

See: http://ruby-doc.org/core/String.html#method-i-5B-5D

Note: str[regexp, capture] ? new_str or nil

Use this function:

function uiTabs(i){
    $("#tabs").tabs("option", "selected", i);
}

And use following code to switch between tabs:

<a onclick="uiTabs(0)">Tab 1</a>
<a onclick="uiTabs(1)">Tab 2</a>
<a onclick="uiTabs(2)">Tab 3</a>

You can add one option to your build for production:

-localWorkers 8 – Where 8 is the number of concurrent threads that calculate permutations. All you have to do is to adjust this number to the number that is more convenient to you. See GWT compilation performance (thanks to Dennis Ich comment).

If you are compiling to the testing environment, you can also use:

-draftCompile which enables faster, but less-optimized compilations

-optimize 0 which does not optimize your code (9 is the max optimization value)

Another thing that more than doubled the build and hosted mode performance was the use of an SSD disk (now hostedmode works like a charm). It's not an cheap solution, but depending on how much you use GWT and the cost of your time, it may worth it!

Hope this helps you!

Your status-codes are also a collection, so use Contains:

var allowedStatus = new[]{ "A", "B", "C" };
var filteredOrders = orders.Order.Where(o => allowedStatus.Contains(o.StatusCode));

or in query syntax:

var filteredOrders = from order in orders.Order
                     where allowedStatus.Contains(order.StatusCode)
                     select order;

The correct fix is to add the property in the type definition as explained by @Nitzan Tomer. But also you can just define property as any, if you want to write code almost as in JavaScript:

arr.filter((item:any) => {
    return item.isSelected == true;
}

Try this coding:

LocationManager locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();

Location location = locationManager.getLastKnownLocation(locationManager.getBestProvider(criteria, false));
if (location != null)
{
    map.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 13));

    CameraPosition cameraPosition = new CameraPosition.Builder()
        .target(new LatLng(location.getLatitude(), location.getLongitude()))      // Sets the center of the map to location user
        .zoom(17)                   // Sets the zoom
        .bearing(90)                // Sets the orientation of the camera to east
        .tilt(40)                   // Sets the tilt of the camera to 30 degrees
        .build();                   // Creates a CameraPosition from the builder
    map.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));       
}

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

The accepted practice if to use the IllegalArgumentException( String message ) to declare a parameter to be invalid and give as much detail as possible... So to say that a parameters was found to be null while exception non-null, you would do something like this:

if( variable == null )
    throw new IllegalArgumentException("The object 'variable' cannot be null");

You have virtually no reason to implicitly use the "NullPointerException". The NullPointerException is an exception thrown by the Java Virtual Machine when you try to execute code on null reference (Like toString()).

The disabled option approach seems to look the best and be the best supported. I've also included an example of using the optgroup.

optgroup (this way kinda sucks):

<select>_x000D_
    <optgroup>_x000D_
        <option>First</option>_x000D_
    </optgroup>_x000D_
    <optgroup label="_________">_x000D_
        <option>Second</option>_x000D_
        <option>Third</option>_x000D_
    </optgroup>_x000D_
</select>

disabled option (a bit better):

<select>_x000D_
    <option>First</option>_x000D_
    <option disabled>_________</option>_x000D_
    <option>Second</option>_x000D_
    <option>Third</option>_x000D_
</select>

And if you want to be really fancy, use the horizontal unicode box drawing character.
(BEST OPTION!)

<select>_x000D_
    <option>First</option>_x000D_
    <option disabled>----------</option>_x000D_
    <option>Second</option>_x000D_
    <option>Third</option>_x000D_
</select>

You can convert the time using the following code.

TimeSpan _time = TimeSpan.Parse("07:35");

But if you want to get the current time of the day you can use the following code:

TimeSpan _CurrentTime = DateTime.Now.TimeOfDay;

The result will be:

03:54:35.7763461

For others facing a similar problem to mine, where you know a particular object property cannot be null, you can use the non-null assertion operator (!) after the item in question. This was my code:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci.certificateStatus = "";
    }
  }

And because dataToSend.naci cannot be undefined in the switch statement, the code can be updated to include exclamation marks as follows:

  const naciStatus = dataToSend.naci?.statusNACI;
  if (typeof naciStatus != "undefined") {
    switch (naciStatus) {
      case "AP":
        dataToSend.naci!.certificateStatus = "FALSE";
        break;
      case "AS":
      case "WR":
        dataToSend.naci!.certificateStatus = "TRUE";
        break;
      default:
        dataToSend.naci!.certificateStatus = "";
    }
  }

Great answers! One thing that I would like to clarify deeper is nonatomic/atomic. The user should understand that this property - "atomicity" spreads only on the attribute's reference and not on it's contents. I.e. atomic will guarantee the user atomicity for reading/setting the pointer and only the pointer to the attribute. For example:

@interface MyClass: NSObject
@property (atomic, strong) NSDictionary *dict;
...

In this case it is guaranteed that the pointer to the dict will be read/set in the atomic manner by different threads. BUT the dict itself (the dictionary dict pointing to) is still thread unsafe, i.e. all read/add operations to the dictionary are still thread unsafe.

If you need thread safe collection you either have bad architecture (more often) OR real requirement (more rare). If it is "real requirement" - you should either find good&tested thread safe collection component OR be prepared for trials and tribulations writing your own one. It latter case look at "lock-free", "wait-free" paradigms. Looks like rocket-science at a first glance, but could help you achieving fantastic performance in comparison to "usual locking".

While it is common for new programmer to make this mistake of performing integer division when they actually meant to use floating point division, in actual practice integer division is a very common operation. If you are assuming that people rarely use it, and that every time you do division you'll always need to remember to cast to floating points, you are mistaken.

First off, integer division is quite a bit faster, so if you only need a whole number result, one would want to use the more efficient algorithm.

Secondly, there are a number of algorithms that use integer division, and if the result of division was always a floating point number you would be forced to round the result every time. One example off of the top of my head is changing the base of a number. Calculating each digit involves the integer division of a number along with the remainder, rather than the floating point division of the number.

Because of these (and other related) reasons, integer division results in an integer. If you want to get the floating point division of two integers you'll just need to remember to cast one to a double/float/decimal.

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

In modern browsers you can do:

.reMode_hover:not(.reMode_selected):hover{}

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

The fix is to ignore loop references and not to serialize them. This behaviour is specified in JsonSerializerSettings.

Single JsonConvert with an overload:

JsonConvert.SerializeObject((from a in db.Events where a.Active select a).ToList(), Formatting.Indented,
    new JsonSerializerSettings() {
        ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
    }
);

If you'd like to make this the default behaviour, add a Global Setting with code in Application_Start() in Global.asax.cs:

JsonConvert.DefaultSettings = () => new JsonSerializerSettings {
     Formatting = Newtonsoft.Json.Formatting.Indented,
     ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore
};

I tried everything but nothing worked.

eventually came up with following solution.

1- in manifest add for the activity android:launchMode="singleTop"

2- while making pending intent do the following, use bundle instead of directly using intent.putString() or intent.putInt()

                    Intent notificationIntent = new Intent(getApplicationContext(), CourseActivity.class);

                    Bundle bundle = new Bundle();
                    bundle.putString(Constants.EXAM_ID,String.valueOf(lectureDownloadStatus.getExamId()));
                    bundle.putInt(Constants.COURSE_ID,(int)lectureDownloadStatus.getCourseId());
                    bundle.putString(Constants.IMAGE_URL,lectureDownloadStatus.getImageUrl());

                    notificationIntent.putExtras(bundle);

                    notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |
                            Intent.FLAG_ACTIVITY_SINGLE_TOP);
                    PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(),
                            new Random().nextInt(), notificationIntent,
                            PendingIntent.FLAG_UPDATE_CURRENT); 

If you will be checking the existence of attributes frequently, I would suggest creating a hasAttr function, to use as you hypothesized in your question:

$.fn.hasAttr = function(name) {  
   return this.attr(name) !== undefined;
};

$(document).ready(function() {
    if($('.edit').hasAttr('id')) {
        alert('true');
    } else {
        alert('false');
    }
});

<div class="edit" id="div_1">Test field</div>

Suppose your class is called MyStudent. Here's how you define your class constructor:

Public Class MyStudent
    Public StudentId As Integer

    'Here's the class constructor:
    Public Sub New(newStudentId As Integer)
        StudentId = newStudentId
    End Sub
End Class

Here's how you call it:

Dim student As New MyStudent(studentId)

Of course, your class constructor can contain as many or as few arguments as you need--even none, in which case you leave the parentheses empty. You can also have several constructors for the same class, all with different combinations of arguments. These are known as different "signatures" for your class constructor.

Using setuptools and pbr

There is not a standard way to manage version, but the standard way to manage your packages is setuptools.

The best solution I've found overall for managing version is to use setuptools with the pbr extension. This is now my standard way of managing version.

Setting up your project for full packaging may be overkill for simple projects, but if you need to manage version, you are probably at the right level to just set everything up. Doing so also makes your package releasable at PyPi so everyone can download and use it with Pip.

PBR moves most metadata out of the setup.py tools and into a setup.cfg file that is then used as a source for most metadata, which can include version. This allows the metadata to be packaged into an executable using something like pyinstaller if needed (if so, you will probably need this info), and separates the metadata from the other package management/setup scripts. You can directly update the version string in setup.cfg manually, and it will be pulled into the *.egg-info folder when building your package releases. Your scripts can then access the version from the metadata using various methods (these processes are outlined in sections below).

When using Git for VCS/SCM, this setup is even better, as it will pull in a lot of the metadata from Git so that your repo can be your primary source of truth for some of the metadata, including version, authors, changelogs, etc. For version specifically, it will create a version string for the current commit based on git tags in the repo.

• PyPA - Packaging Python Packages with SetupTools - Tutorial
• PBR latest build usage documentation - How to setup an 8-line setup.py and a setup.cfg file with the metadata.

As PBR will pull version, author, changelog and other info directly from your git repo, so some of the metadata in setup.cfg can be left out and auto generated whenever a distribution is created for your package (using setup.py)

Get the current version in real-time

setuptools will pull the latest info in real-time using setup.py:

python setup.py --version

This will pull the latest version either from the setup.cfg file, or from the git repo, based on the latest commit that was made and tags that exist in the repo. This command doesn't update the version in a distribution though.

Updating the version metadata

When you create a distribution with setup.py (i.e. py setup.py sdist, for example), then all the current info will be extracted and stored in the distribution. This essentially runs the setup.py --version command and then stores that version info into the package.egg-info folder in a set of files that store distribution metadata.

Note on process to update version meta-data:

If you are not using pbr to pull version data from git, then just update your setup.cfg directly with new version info (easy enough, but make sure this is a standard part of your release process).

If you are using git, and you don't need to create a source or binary distribution (using python setup.py sdist or one of the python setup.py bdist_xxx commands) the simplest way to update the git repo info into your <mypackage>.egg-info metadata folder is to just run the python setup.py install command. This will run all the PBR functions related to pulling metadata from the git repo and update your local .egg-info folder, install script executables for any entry-points you have defined, and other functions you can see from the output when you run this command.

Note that the .egg-info folder is generally excluded from being stored in the git repo itself in standard Python .gitignore files (such as from Gitignore.IO), as it can be generated from your source. If it is excluded, make sure you have a standard "release process" to get the metadata updated locally before release, and any package you upload to PyPi.org or otherwise distribute must include this data to have the correct version. If you want the Git repo to contain this info, you can exclude specific files from being ignored (i.e. add !*.egg-info/PKG_INFO to .gitignore)

Accessing the version from a script

You can access the metadata from the current build within Python scripts in the package itself. For version, for example, there are several ways to do this I have found so far:

## This one is a new built-in as of Python 3.8.0 should become the standard
from importlib-metadata import version

v0 = version("mypackage")
print('v0 {}'.format(v0))

## I don't like this one because the version method is hidden
import pkg_resources  # part of setuptools

v1 = pkg_resources.require("mypackage")[0].version
print('v1 {}'.format(v1))

# Probably best for pre v3.8.0 - the output without .version is just a longer string with
# both the package name, a space, and the version string
import pkg_resources  # part of setuptools

v2 = pkg_resources.get_distribution('mypackage').version
print('v2 {}'.format(v2))

## This one seems to be slower, and with pyinstaller makes the exe a lot bigger
from pbr.version import VersionInfo

v3 = VersionInfo('mypackage').release_string()
print('v3 {}'.format(v3))

You can put one of these directly in your __init__.py for the package to extract the version info as follows, similar to some other answers:

__all__ = (
    '__version__',
    'my_package_name'
)

import pkg_resources  # part of setuptools

__version__ = pkg_resources.get_distribution("mypackage").version

logger logs to syslog facilities. If you want the message to go to a particular file you have to modify the syslog configuration accordingly. You could add a line like this:

local7.*   -/var/log/mycustomlog

and restart syslog. Then you can log like this:

logger -p local7.info "information message"
logger -p local7.err "error message"

and the messages will appear in the desired logfile with the correct log level.

Without making changes to the syslog configuration you could use logger like this:

logger -s "foo bar" >> /var/log/mycustomlog

That would instruct logger to print the message to STDERR as well (in addition to logging it to syslog), so you could redirect STDERR to a file. However, it would be utterly pointless, because the message is already logged via syslog anyway (with the default priority user.notice).

these are primitive data types

• boolean
• character
• byte
• short
• integer
• long
• float
• double

saved in stack in the memory which is managed memory on the other hand object data type or reference data type stored in head in the memory managed by GC

this is the most important difference

Here is PostgreSQL example without trigger if someone need it on PostgreSQL:

CREATE SEQUENCE messages_seq;

 CREATE TABLE IF NOT EXISTS messages (
    id CHAR(20) NOT NULL DEFAULT ('message_' || nextval('messages_seq')),
    name CHAR(30) NOT NULL,
);

ALTER SEQUENCE messages_seq OWNED BY messages.id;

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

Try BeanComparator from Apache Commons.

import org.apache.commons.beanutils.BeanComparator;


BeanComparator fieldComparator = new BeanComparator("fruitName");
Collections.sort(fruits, fieldComparator);

Could it be a one to many relationship between the left and right tables?

it works:

type HtmlEvent = React.ChangeEvent<HTMLSelectElement>

const onChange: React.EventHandler<HtmlEvent> = 
   (event: HtmlEvent) => { 
       console.log(event.target.value) 
   }

Try giving 5 ',' in every line, similar to line number 4.

The W3C doc doesn't use concepts like wrong and sin, but it does use those like provide the means, may be appropriate and discouraged.

Actually, in the second paragraph of section 4, the 4.01 spec itemizes its words as follows

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. However, for readability, these words do not appear in all uppercase letters in this specification.

With that in mind, I believe the definitive statement is in 7.5.3 Block-level and inline elements, where it says

Generally, inline elements may contain only data and other inline elements.

The condition "generally" appears to introduce enough ambiguity to say that HTML 4.01 does allow inline elements to contain block elements.

Certainly, CSS2 has a display property value, inline-block, that appears to be suited to the purpose you describe. I'm not sure if it was ever widely supported, but it seems that someone anticipated the need for that kind of behavior.

The DTD appear to be less forgiving here, but the text of the DTD defers to the spec:

The HTML 4.01 specification includes additional syntactic constraints that cannot be expressed within the DTDs.

In another comment, you suggest that you want to make a block active by wrapping it in an anchor. I don't believe HTML prohibits that, and CSS clearly allows it. So to answer the title question about whether it is ever correct, I say yes. By the standards, it is sometimes correct.

I'm late to this party but I'll offer my approach for any passersby that might be interested in an alternative.

As noted in previous answers, the System.Net.Mail SmtpClient class does not support Implicit SSL. It does support Explicit SSL, which requires an insecure connection to the SMTP server over port 25 in order to negotiate the transport level security (TLS). I blogged about my travails with this subtlety here.

In short, SMTP over Implict SSL port 465 requires TLS to be negotiated before connecting to the SMTP server. Rather than write a .Net SMTPS implementation I turned to a utility named Stunnel. It's a small service that will let you redirect traffic on a local port to a remote port via SSL.

DISCLAIMER: Stunnel uses portions of the OpenSSL library, which recently had a high-profile exploit published in all major tech news media. I believe the latest version uses the patched OpenSSL but please use at your own risk.

Once the utility is installed a small addition to the configuration file:

; Example SSL client mode services
[my-smtps]
client = yes
accept = 127.0.0.1:465
connect = mymailserver.com:465

...instructs the Stunnel service to reroute local requests to port 465 to my mail server on port 465. This happens over TLS, which satisfies the SMTP server on the other end.

Using this utility, the following code will successfully transmit over port 465:

using System;
using System.Net;
using System.Net.Mail;

namespace RSS.SmtpTest
{
    class Program
    {
        static void Main( string[] args )
        {
            try {
                using( SmtpClient smtpClient = new SmtpClient( "localhost", 465 ) ) { // <-- note the use of localhost
                    NetworkCredential creds = new NetworkCredential( "username", "password" );
                    smtpClient.Credentials = creds;
                    MailMessage msg = new MailMessage( "[email protected]", "[email protected]", "Test", "This is a test" );
                    smtpClient.Send( msg );
                }
            }
            catch( Exception ex ) {
                Console.WriteLine( ex.Message );
            }
        }
    }
}

So the advantage here is that you can use Implict SSL and port 465 as the security protocol while still using the send mail methods built into the framework. The disadvantage is that it requires the use of a third party service that may not be useful for anything but this specific function.

It is mentioned under "Index expressions".

An index expression on a map a of type map[K]V used in an assignment or initialization of the special form

v, ok = a[x] 
v, ok := a[x] 
var v, ok = a[x]

yields an additional untyped boolean value. The value of ok is true if the key x is present in the map, and false otherwise.

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

this is my approach to solve this generally. It extends the answer from Steve Jessop by removing the requirement to set template arguments explicitly and adding the option to also use functoins and pointers to methods (getters)

I don't know if it is a solution but Invalidate Cache and Restart solved this problem in my case. I am currently using Android Studio 3.6

I wrote following function to return a default representation 0 or false of a primitive or Number:

 */

        return (T) new Long(0);

        return (T) new Integer(0);
    else if (type.equals(Double.class) || type.equals(Double.TYPE))
        return (T) new Double(0);

One of the many unnecessary complex things about Java making it unintuitive to use. Why instance variables are initialized with default 0 but local are not is not logical. Similar why enums dont have built in flag support and many more options. Java lambda is a nightmare compared to C# and not allowing class extension methods is also a big problem.

Java ecosystem comes up with excuses why its not possible but me as the user / developer i dont care about their excuses. I want easy approach and if they dont fix those things they will loose big in the future since C# and other languages are not waiting to make life of developers more simple. Its just sad to see the decline in the last 10 years since i work daily with Java.

• Choose type of iterator which fits your container: input, output, forward etc.
• Use base iterator classes from standard library. For example, std::iterator with random_access_iterator_tag.These base classes define all type definitions required by STL and do other work.

• To avoid code duplication iterator class should be a template class and be parametrized by "value type", "pointer type", "reference type" or all of them (depends on implementation). For example:

  // iterator class is parametrized by pointer type
  template <typename PointerType> class MyIterator {
      // iterator class definition goes here
  };
  
  typedef MyIterator<int*> iterator_type;
  typedef MyIterator<const int*> const_iterator_type;
  

  Notice iterator_type and const_iterator_type type definitions: they are types for your non-const and const iterators.

See Also: standard library reference

EDIT: std::iterator is deprecated since C++17. See a relating discussion here.

string userRequest = System.Web.HttpContext.Current.Request.UserHostAddress;

This works on me.

System.Web.HttpContext.Current.Request.UserHostName; this one return me the same return I get from the UserHostAddress.

For C++, there really isn't much of a difference between structs and classes. The main functional difference is that members of a struct are public by default, while they are private by default in classes. Otherwise, as far as the language is concerned, they are equivalent.

That said, I tend to use structs in C++ like I do in C#, similar to what Brian has said. Structs are simple data containers, while classes are used for objects that need to act on the data in addition to just holding on to it.

Note: I found this question looking for one of the steps in the answer to how to resize an existing array.

So I thought I would add that information here, in case anyone else was searching for how to do a ranged copy as a partial answer to the question of resizing an array.

For anyone else finding this question looking for the same thing I was, it is very simple:

Array.Resize<T>(ref arrayVariable, newSize);

where T is the type, i.e. where arrayVariable is declared:

T[] arrayVariable;

That method handles null checks, as well as newSize==oldSize having no effect, and of course silently handles the case where one of the arrays is longer than the other.

See the MSDN article for more.

It's actually a sensible question. Here's the answer from Excel 2010 help:

"The Workbook object is a member of the Workbooks collection. The Workbooks collection contains all the Workbook objects currently open in Microsoft Excel."

So, since that workbook isn't open - at least I assume it isn't - it can't be set as a workbook object. If it was open you'd just set it like:

Set wbk = workbooks("Master Benchmark Data Sheet.xlsx")

Instead of implementing interface View.OnClickListener inside view holder or creating and interface and implementing interface in your activity.. I used this code for simple on OnClickListener implementation.

public static class SimpleStringRecyclerViewAdapter
            extends RecyclerView.Adapter<SimpleStringRecyclerViewAdapter.ViewHolder> {

        // Your initializations goes here...
        private List<String> mValues;

        public static class ViewHolder extends RecyclerView.ViewHolder {

            //create a variable mView
            public final View mView;

            /*All your row widgets goes here
            public final ImageView mImageView;
            public final TextView mTextView;*/

            public ViewHolder(View view) {
                super(view);
                //Initialize it here
                mView = view;

                /* your row widgets initializations goes here
                mImageView = (ImageView) view.findViewById(R.id.avatar);
                mTextView = (TextView) view.findViewById(android.R.id.text1);*/
            }
        }

        public String getValueAt(int position) {
            return mValues.get(position);
        }

        public SimpleStringRecyclerViewAdapter(Context context, List<String> items) {

            mBackground = mTypedValue.resourceId;
            mValues = items;
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.list_item, parent, false);
            view.setBackgroundResource(mBackground);
            return new ViewHolder(view);
        }

        @Override
        public void onBindViewHolder(final ViewHolder holder, int position) {
            holder.mBoundString = mValues.get(position);
            holder.mTextView.setText(mValues.get(position));

            //Here it is simply write onItemClick listener here
            holder.mView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Context context = v.getContext();
                    Intent intent = new Intent(context, ExampleActivity.class);

                    context.startActivity(intent);
                }
            });
        }

        @Override
        public int getItemCount() {
            return mValues.size();
        }
    }

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

Simply using an outer directory for the output, solved the problem for me.

sudo tar czf ./../31OCT18.tar.gz ./

No promises are just wrapper on callbacks

example You can use javascript native promises with node js

    if (!error && response.statusCode == 200) {
        resolve(body);
    }
    else {
        reject(error);
    }
    })
    });
}

//get all the albums of a user who have posted post 100
app.get('/listAlbums', function (req, res) {

For small scripts an optional way to make it readable is to use a variable like this:

awk -v fmt="'%s'\n" '{printf fmt, $1}'

I found it conveninet in a case where I had to produce many times the single-quote character in the output and the \047 were making it totally unreadable

I usually use a little modified version of ngLink's answer.

public class MyControl : Control
{
    private int suspendCounter = 0;

    private void SuspendDrawing()
    {
        if(suspendCounter == 0) 
            SendMessage(this.Handle, WM_SETREDRAW, false, 0);
        suspendCounter++;
    }

    private void ResumeDrawing()
    {
        suspendCounter--; 
        if(suspendCounter == 0) 
        {
            SendMessage(this.Handle, WM_SETREDRAW, true, 0);
            this.Refresh();
        }
    }
}

This allows suspend/resume calls to be nested. You must make sure to match each SuspendDrawing with a ResumeDrawing. Hence, it wouldn't probably be a good idea to make them public.

There is no DrawCircle method; use DrawEllipse instead. I have a static class with handy graphics extension methods. The following ones draw and fill circles. They are wrappers around DrawEllipse and FillEllipse:

public static class GraphicsExtensions
{
    public static void DrawCircle(this Graphics g, Pen pen,
                                  float centerX, float centerY, float radius)
    {
        g.DrawEllipse(pen, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }

    public static void FillCircle(this Graphics g, Brush brush,
                                  float centerX, float centerY, float radius)
    {
        g.FillEllipse(brush, centerX - radius, centerY - radius,
                      radius + radius, radius + radius);
    }
}

You can call them like this:

g.FillCircle(myBrush, centerX, centerY, radius);
g.DrawCircle(myPen, centerX, centerY, radius);

run cmd.exe and do the following:

> cd "long path name"
> command

Then command.com will come up and display only short paths.

Gson allows for one of the simplest possible solutions. Compared to similar APIs like Jackson or svenson, Gson by default doesn't even need the unused JSON elements to have bindings available in the Java structure. Specific to the question asked, here's a working solution.

import com.google.gson.Gson;

public class Foo
{
  static String jsonInput = 
    "{" + 
      "\"name\":\"John\"," + 
      "\"age\":\"20\"," + 
      "\"address\":\"some address\"," + 
      "\"someobject\":" +
      "{" + 
        "\"field\":\"value\"" + 
      "}" + 
    "}";

  String age;

  public static void main(String[] args) throws Exception
  {
    Gson gson = new Gson();
    Foo thing = gson.fromJson(jsonInput, Foo.class);
    if (thing.age != null)
    {
      System.out.println("age is " + thing.age);
    }
    else
    {
      System.out.println("age element not present or value is null");
    }
  }
}

Try -

Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)

As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.

You can easily create a static object that represents a NULL return.

class Attr;
extern Attr AttrNull;

class Node { 
.... 

Attr& getAttribute(const string& attribute_name) const { 
   //search collection 
   //if found at i 
        return attributes[i]; 
   //if not found 
        return AttrNull; 
} 

bool IsNull(const Attr& test) const {
    return &test == &AttrNull;
}

 private: 
   vector<Attr> attributes; 
};

And somewhere in a source file:

static Attr AttrNull;

You were almost done without any changes besides how you spyOn. When you use the spy, you have two options: spyOn the App.prototype, or component component.instance().

const spy = jest.spyOn(Class.prototype, "method")

The order of attaching the spy on the class prototype and rendering (shallow rendering) your instance is important.

const spy = jest.spyOn(App.prototype, "myClickFn");
const instance = shallow(<App />);

The App.prototype bit on the first line there are what you needed to make things work. A JavaScript class doesn't have any of its methods until you instantiate it with new MyClass(), or you dip into the MyClass.prototype. For your particular question, you just needed to spy on the App.prototype method myClickFn.

jest.spyOn(component.instance(), "method")

const component = shallow(<App />);
const spy = jest.spyOn(component.instance(), "myClickFn");

This method requires a shallow/render/mount instance of a React.Component to be available. Essentially spyOn is just looking for something to hijack and shove into a jest.fn(). It could be:

A plain object:

const obj = {a: x => (true)};
const spy = jest.spyOn(obj, "a");

A class:

class Foo {
    bar() {}
}

const nope = jest.spyOn(Foo, "bar");
// THROWS ERROR. Foo has no "bar" method.
// Only an instance of Foo has "bar".
const fooSpy = jest.spyOn(Foo.prototype, "bar");
// Any call to "bar" will trigger this spy; prototype or instance

const fooInstance = new Foo();
const fooInstanceSpy = jest.spyOn(fooInstance, "bar");
// Any call fooInstance makes to "bar" will trigger this spy.

Or a React.Component instance:

const component = shallow(<App />);
/*
component.instance()
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(component.instance(), "myClickFn");

Or a React.Component.prototype:

/*
App.prototype
-> {myClickFn: f(), render: f(), ...etc}
*/
const spy = jest.spyOn(App.prototype, "myClickFn");
// Any call to "myClickFn" from any instance of App will trigger this spy.

I've used and seen both methods. When I have a beforeEach() or beforeAll() block, I might go with the first approach. If I just need a quick spy, I'll use the second. Just mind the order of attaching the spy.

EDIT: If you want to check the side effects of your myClickFn you can just invoke it in a separate test.

const app = shallow(<App />);
app.instance().myClickFn()
/*
Now assert your function does what it is supposed to do...
eg.
expect(app.state("foo")).toEqual("bar");
*/

EDIT: Here is an example of using a functional component. Keep in mind that any methods scoped within your functional component are not available for spying. You would be spying on function props passed into your functional component and testing the invocation of those. This example explores the use of jest.fn() as opposed to jest.spyOn, both of which share the mock function API. While it does not answer the original question, it still provides insight on other techniques that could suit cases indirectly related to the question.

function Component({ myClickFn, items }) {
   const handleClick = (id) => {
       return () => myClickFn(id);
   };
   return (<>
       {items.map(({id, name}) => (
           <div key={id} onClick={handleClick(id)}>{name}</div>
       ))}
   </>);
}

const props = { myClickFn: jest.fn(), items: [/*...{id, name}*/] };
const component = render(<Component {...props} />);
// Do stuff to fire a click event
expect(props.myClickFn).toHaveBeenCalledWith(/*whatever*/);

Value for network.proxy.http_port should be integer (no quotes should be used) and network.proxy.type should be set as 1 (ProxyType.MANUAL, Manual proxy settings)

profile.setPreference("network.proxy.type", 1);
profile.setPreference("network.proxy.http", "localhost");
profile.setPreference("network.proxy.http_port", 3128);
WebDriver driver = new FirefoxDriver(profile);

No, there are definitely times where you would not want to use [unowned self]. Sometimes you want the closure to capture self in order to make sure that it is still around by the time the closure is called.

Example: Making an asynchronous network request

If you are making an asynchronous network request you do want the closure to retain self for when the request finishes. That object may have otherwise been deallocated but you still want to be able to handle the request finishing.

When to use unowned self or weak self

The only time where you really want to use [unowned self] or [weak self] is when you would create a strong reference cycle. A strong reference cycle is when there is a loop of ownership where objects end up owning each other (maybe through a third party) and therefore they will never be deallocated because they are both ensuring that each other stick around.

In the specific case of a closure, you just need to realize that any variable that is referenced inside of it, gets "owned" by the closure. As long as the closure is around, those objects are guaranteed to be around. The only way to stop that ownership, is to do the [unowned self] or [weak self]. So if a class owns a closure, and that closure captures a strong reference to that class, then you have a strong reference cycle between the closure and the class. This also includes if the class owns something that owns the closure.

Specifically in the example from the video

In the example on the slide, TempNotifier owns the closure through the onChange member variable. If they did not declare self as unowned, the closure would also own self creating a strong reference cycle.

Difference between unowned and weak

The difference between unowned and weak is that weak is declared as an Optional while unowned is not. By declaring it weak you get to handle the case that it might be nil inside the closure at some point. If you try to access an unowned variable that happens to be nil, it will crash the whole program. So only use unowned when you are positive that variable will always be around while the closure is around

The

(condition) ? /* value to return if condition is true */ 
            : /* value to return if condition is false */ ;

syntax is not a "shorthand if" operator (the ? is called the conditional operator) because you cannot execute code in the same manner as if you did:

if (condition) {
    /* condition is true, do something like echo */
}
else {
    /* condition is false, do something else */
}

In your example, you are executing the echo statement when the $address is not empty. You can't do this the same way with the conditional operator. What you can do however, is echo the result of the conditional operator:

echo empty($address['street2']) ? "Street2 is empty!" : $address['street2'];

and this will display "Street is empty!" if it is empty, otherwise it will display the street2 address.

For my issue, I didn't want my images scaled to 100% when they weren't intended to be as large as the container.

For my xs container (<768px as .container), not having a fixed width drove the issue, so I put one back on to it (less the 15px col padding).

// Helps bootstrap 3.0 keep images constrained to container width when width isn't set a fixed value (below 768px), while avoiding all images at 100% width.
// NOTE: proper function relies on there being no inline styling on the element being given a defined width ( '.container'  )

function setWidth() {
    width_val = $( window ).width();
    if( width_val < 768 ) {
        $( '.container' ).width( width_val - 30 );
    } else {
        $( '.container' ).removeAttr( 'style' );
    }
}

setWidth();
$( window ).resize( setWidth );

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

import codecs
f=codecs.open("test.html", 'r')
print f.read()

Try something like this.

You could also try the Visual Studio Android Emulator, which can also be installed as a standalone emulator (you don't need Visual Studio). Please note, that it can be installed only on Windows Pro or higher systems.

I'm using the environment variable COMPUTERNAME:

I know that it is very late to answer the question, but it may help someone like me who spent lots off time to fetch data using hql

So the thing is you just have to write a query

Query query = session.createQuery("from Employee");

it will give you all the data list but to fetch data from this you have to write this line.

List<Employee> fetchedData = query.list();

As simple as it looks.

there is much easier solution:

    [self drawAtPoint:CGPointZero blendMode:kCGBlendModeNormal alpha:alpha];
    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image;
}

The problem with both iDevlop's and Ashok's answers is that the fundamental problem is an Excel design flaw (apparently) in which the Open method fails to respect the Application.ScreenUpdating setting of False. Consequently, setting it to False is of no benefit to this problem.

If Patrick McDonald's solution is too burdensome due to the overhead of starting a second instance of Excel, then the best solution I've found is to minimize the time that the opened workbook is visible by re-activating the original window as quickly as possible:

Dim TempWkBk As Workbook
Dim CurrentWin As Window

Set CurrentWin = ActiveWindow
Set TempWkBk = Workbooks.Open(SomeFilePath)
CurrentWin.Activate      'Allows only a VERY brief flash of the opened workbook
TempWkBk.Windows(1).Visible = False 'Only necessary if you also need to prevent
                                    'the user from manually accessing the opened
                                    'workbook before it is closed.

'Operate on the new workbook, which is not visible to the user, then close it...

I recently ditched Xampp in favor of the native Apache on Mac Sierra because a new php requirement of a project. Sierra comes with php 5.6.25, but it doesn't run mysql_* out of the box, after a lot of googling, I found this site really help - https://php-osx.liip.ch. As it turns out php 5.6.25 does support mysql_* but wasn't enabled. Choose your version of php and download it, it generates a proper php.ini for your php, then you are good to go

Try this part of code:

void containsOnlyNumbers(String str)
{
    try {
        Integer num = Integer.valueOf(str);
        System.out.println("is a number");
    } catch (NumberFormatException e) {
        // TODO: handle exception
        System.out.println("is not a number");
    }

}

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.

If you use the Logcat display inside the 'debug' perspective in Eclipse the lines are colour-coded. It's pretty easy to find what made your app crash because it's usually in red.

The Java (or Dalvik) virtual machine should never crash, but if your program throws an exception and does not catch it the VM will terminate your program, which is the 'crash' you are seeing.

Neither "new" or "delete" should ever be used in application code. Instead, create a new type that uses the manager/worker idiom, in which the manager class allocates and frees memory and forwards all other operations to the worker object.

Unfortunately this is more work than it should be because C++ doesn't have overloading of "operator .". It is even more work in the presence of polymorphism.

But this is worth the effort because you then don't ever have to worry about memory leaks, which means you don't even have to look for them.

Just out of interest, if you want to center two or more divs (so they're side by side in the center), then here's how to do it:

    <div style="border:1px solid #000; display:inline-block;">Div 1</div>
    <div style="border:1px solid red; display:inline-block;">Div 2</div>

Took me ages to figure it out with Spark 2.0.2, but here's my bit:

val sparkBuilder = SparkSession.builder
.appName("app_name")
.master("local")
// Various Params
.getOrCreate()

val hadoopConfig: Configuration = sparkBuilder.sparkContext.hadoopConfiguration

hadoopConfig.set("fs.hdfs.impl", classOf[org.apache.hadoop.hdfs.DistributedFileSystem].getName)

hadoopConfig.set("fs.file.impl", classOf[org.apache.hadoop.fs.LocalFileSystem].getName)

And the relevant parts of my build.sbt:

scalaVersion := "2.11.8"
libraryDependencies += "org.apache.spark" %% "spark-core" % "2.0.2"

I hope this can help!

When your website is served by only one web server, for each client-server pair, a session object is created and remains in the memory of the web server. All the requests from the client go to this web server and update this session object. If some data needs to be stored in the session object over the period of interaction, it is stored in this session object and stays there as long as the session exists.

However, if your website is served by multiple web servers which sit behind a load balancer, the load balancer decides which actual (physical) web-server should each request go to. For example, if there are 3 web servers A, B and C behind the load balancer, it is possible that www.mywebsite.com/index.jsp is served from server A, www.mywebsite.com/login.jsp is served from server B and www.mywebsite.com/accoutdetails.php are served from server C.

Now, if the requests are being served from (physically) 3 different servers, each server has created a session object for you and because these session objects sit on three independent boxes, there's no direct way of one knowing what is there in the session object of the other. In order to synchronize between these server sessions, you may have to write/read the session data into a layer which is common to all - like a DB. Now writing and reading data to/from a db for this use-case may not be a good idea. Now, here comes the role of sticky-session.

If the load balancer is instructed to use sticky sessions, all of your interactions will happen with the same physical server, even though other servers are present. Thus, your session object will be the same throughout your entire interaction with this website.

To summarize, In case of Sticky Sessions, all your requests will be directed to the same physical web server while in case of a non-sticky loadbalancer may choose any webserver to serve your requests.

As an example, you may read about Amazon's Elastic Load Balancer and sticky sessions here : http://aws.typepad.com/aws/2010/04/new-elastic-load-balancing-feature-sticky-sessions.html

For mac :

I have added below two commands its working fine!

-vm
/usr/bin
/usr/libexec/java_home --verbose

Example

How about:

df . -B MB | tail -1 | awk {'print $4'} | cut -d'%' -f1

It's simplest to just call the function yourself directly the first time:

foo();
setInterval(foo, delay);

However there are good reasons to avoid setInterval - in particular in some circumstances a whole load of setInterval events can arrive immediately after each other without any delay. Another reason is that if you want to stop the loop you have to explicitly call clearInterval which means you have to remember the handle returned from the original setInterval call.

So an alternative method is to have foo trigger itself for subsequent calls using setTimeout instead:

function foo() {
   // do stuff
   // ...

   // and schedule a repeat
   setTimeout(foo, delay);
}

// start the cycle
foo();

This guarantees that there is at least an interval of delay between calls. It also makes it easier to cancel the loop if required - you just don't call setTimeout when your loop termination condition is reached.

Better yet, you can wrap that all up in an immediately invoked function expression which creates the function, which then calls itself again as above, and automatically starts the loop:

(function foo() {
    ...
    setTimeout(foo, delay);
})();

which defines the function and starts the cycle all in one go.

It seems that the most accurate (and seamless) method of adding the padding for iPhone X/8 using env()...

padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);

Here's a link describing this:

This will find the first parent with class box then find the first child class with regex matching something and get the id.

$(".mylink").closest(".box").find('[class*="something"]').first().attr("id")

The best way I found to make this to my purpose was to increment from the max value you have in the field and for that, I used the following syntax:

maxObj = db.CollectionName.aggregate([
  {
    $group : { _id: '$item', maxValue: { $max: '$fieldName' } } 
  }
];
fieldNextValue = maxObj.maxValue + 1;

$fieldName is the name of your field, but without the $ sign.

CollectionName is the name of your collection.

The reason I am not using count() is that the produced value could meet an existing value.

The creation of an enforcing unique index could make it safer:

db.CollectionName.createIndex( { "fieldName": 1 }, { unique: true } )

Yes. You know that you can put any Object into the Object parameter of most JOptionPane.showXXX methods, and often that Object happens to be a JPanel.

In your situation, perhaps you could use a JPanel that has several JTextFields in it:

import javax.swing.*;

public class JOptionPaneMultiInput {
   public static void main(String[] args) {
      JTextField xField = new JTextField(5);
      JTextField yField = new JTextField(5);

      JPanel myPanel = new JPanel();
      myPanel.add(new JLabel("x:"));
      myPanel.add(xField);
      myPanel.add(Box.createHorizontalStrut(15)); // a spacer
      myPanel.add(new JLabel("y:"));
      myPanel.add(yField);

      int result = JOptionPane.showConfirmDialog(null, myPanel, 
               "Please Enter X and Y Values", JOptionPane.OK_CANCEL_OPTION);
      if (result == JOptionPane.OK_OPTION) {
         System.out.println("x value: " + xField.getText());
         System.out.println("y value: " + yField.getText());
      }
   }
}

Use jQuery

Look how easy it would be if you did.

Example:

$('#td1').html('hello world');

In Layout

<EditText  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:textCursorDrawable="@drawable/color_cursor"
    />

Then create drawalble xml: color_cursor

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
    <size android:width="3dp" />
    <solid android:color="#FFFFFF"  />
</shape>

You have a white color cursor on EditText property.

The idiomatic way to do this with Pandas is to use the .sample method of your dataframe to sample all rows without replacement:

df.sample(frac=1)

The frac keyword argument specifies the fraction of rows to return in the random sample, so frac=1 means return all rows (in random order).

Note: If you wish to shuffle your dataframe in-place and reset the index, you could do e.g.

df = df.sample(frac=1).reset_index(drop=True)

Here, specifying drop=True prevents .reset_index from creating a column containing the old index entries.

Follow-up note: Although it may not look like the above operation is in-place, python/pandas is smart enough not to do another malloc for the shuffled object. That is, even though the reference object has changed (by which I mean id(df_old) is not the same as id(df_new)), the underlying C object is still the same. To show that this is indeed the case, you could run a simple memory profiler:

$ python3 -m memory_profiler .\test.py
Filename: .\test.py

Line #    Mem usage    Increment   Line Contents
================================================
     5     68.5 MiB     68.5 MiB   @profile
     6                             def shuffle():
     7    847.8 MiB    779.3 MiB       df = pd.DataFrame(np.random.randn(100, 1000000))
     8    847.9 MiB      0.1 MiB       df = df.sample(frac=1).reset_index(drop=True)

maybe map, but since you don't want to make a list, you can write your own...

def call_for_all(f, seq):
    for i in seq:
        f(i)

then you can do:

call_for_all(lamda x: x.start(), all)
call_for_all(lamda x: x.stop(), all)

by the way, all is a built in function, don't overwrite it ;-)

As other noted you have several options. If you want only mathematical functions. You can import only Darwin.

If you want mathematical functions and other standard classes and functions. You can import Foundation.

If you want everything and also classes for user interface, it depends if your playground is for OS X or iOS.

For OS X, you need import Cocoa.

For iOS, you need import UIKit.

Try to make your javascript unobtrusive :

• you should use a real link in href attribute
• and add a listener on click event to handle ajax

function function_one() {_x000D_
    function_two(); // considering the next alert, I figured you wanted to call function_two first_x000D_
    alert("The function called 'function_one' has been called.");_x000D_
}_x000D_
_x000D_
function function_two() {_x000D_
    alert("The function called 'function_two' has been called.");_x000D_
}_x000D_
_x000D_
function_one();

A little bit more context: this works in JavaScript because of a language feature called "variable hoisting" - basically, think of it like variable/function declarations are put at the top of the scope (more info).

bash 5.1 introduces a new variable, SRANDOM, which gets its random data from the system's entropy engine and so is not linear and cannot be reseeded to get an identical random sequence. This variable can be used as a substitute for RANDOM for generating more random numbers.

Here is some interesting information about SET / SELECT

• SET is the ANSI standard for variable assignment, SELECT is not.
• SET can only assign one variable at a time, SELECT can make multiple assignments at once.
• If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
• When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
• As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.

Try this code:

{% for i in loop_times %}
        <option value={{ i }}>{{ i }}</option>
{% endfor %}

Here is the solution. I have fixed it. Here is the code

child: _status(data[index]["status"]),

Widget _status(status) {
  if (status == "3") {
    return Text('Process');
  } else if(status == "1") {
    return Text('Order');
  } else {
    return Text("Waiting");
  }
}

In your second function remove the e variable in the catch block then add throw.

This will carry over the generated exception the the final function and output it.

Its very common when you dont want your business logic code to throw exception but your UI.

This all depends on what sort of access you have to your SAP system. An ABAP program that exports the data and/or an RFC that your macro can call to directly get the data or have SAP create the file is probably best.

However as a general rule people looking for this sort of answer are looking for an immediate solution that does not require their IT department to spend months customizing their SAP system.

In that case you probably want to use SAP GUI Scripting. SAP GUI scripting allows you to automate the Windows SAP GUI in much the same way as you automate Excel. In fact you can call the SAP GUI directly from an Excel macro. Read up more on it here. The SAP GUI has a macro recording tool much like Excel does. It records macros in VBScript which is nearly identical to Excel VBA and can usually be copied and pasted into an Excel macro directly.

Example Code

Here is a simple example based on a SAP system I have access to.

Public Sub SimpleSAPExport()
  Set SapGuiAuto  = GetObject("SAPGUI") 'Get the SAP GUI Scripting object
  Set SAPApp = SapGuiAuto.GetScriptingEngine 'Get the currently running SAP GUI 
  Set SAPCon = SAPApp.Children(0) 'Get the first system that is currently connected
  Set session = SAPCon.Children(0) 'Get the first session (window) on that connection

  'Start the transaction to view a table
  session.StartTransaction "SE16"

  'Select table T001
  session.findById("wnd[0]/usr/ctxtDATABROWSE-TABLENAME").Text = "T001"
  session.findById("wnd[0]/tbar[1]/btn[7]").Press

  'Set our selection criteria
  session.findById("wnd[0]/usr/txtMAX_SEL").text = "2"
  session.findById("wnd[0]/tbar[1]/btn[8]").press

  'Click the export to file button
  session.findById("wnd[0]/tbar[1]/btn[45]").press

  'Choose the export format
  session.findById("wnd[1]/usr/subSUBSCREEN_STEPLOOP:SAPLSPO5:0150/sub:SAPLSPO5:0150/radSPOPLI-SELFLAG[1,0]").select
  session.findById("wnd[1]/tbar[0]/btn[0]").press

  'Choose the export filename
  session.findById("wnd[1]/usr/ctxtDY_FILENAME").text = "test.txt"
  session.findById("wnd[1]/usr/ctxtDY_PATH").text = "C:\Temp\"

  'Export the file
  session.findById("wnd[1]/tbar[0]/btn[0]").press
End Sub

Script Recording

To help find the names of elements such aswnd[1]/tbar[0]/btn[0] you can use script recording. Click the customize local layout button, it probably looks a bit like this:
Then find the Script Recording and Playback menu item.

Within that the More button allows you to see/change the file that the VB Script is recorded to. The output format is a bit messy, it records things like selecting text, clicking inside a text field, etc.

Edit: Early and Late binding

The provided script should work if copied directly into a VBA macro. It uses late binding, the line Set SapGuiAuto = GetObject("SAPGUI") defines the SapGuiAuto object.

If however you want to use early binding so that your VBA editor might show the properties and methods of the objects you are using, you need to add a reference to sapfewse.ocx in the SAP GUI installation folder.

Because floats and doubles cannot accurately represent the base 10 multiples that we use for money. This issue isn't just for Java, it's for any programming language that uses base 2 floating-point types.

In base 10, you can write 10.25 as 1025 * 10^-2 (an integer times a power of 10). IEEE-754 floating-point numbers are different, but a very simple way to think about them is to multiply by a power of two instead. For instance, you could be looking at 164 * 2^-4 (an integer times a power of two), which is also equal to 10.25. That's not how the numbers are represented in memory, but the math implications are the same.

Even in base 10, this notation cannot accurately represent most simple fractions. For instance, you can't represent 1/3: the decimal representation is repeating (0.3333...), so there is no finite integer that you can multiply by a power of 10 to get 1/3. You could settle on a long sequence of 3's and a small exponent, like 333333333 * 10^-10, but it is not accurate: if you multiply that by 3, you won't get 1.

However, for the purpose of counting money, at least for countries whose money is valued within an order of magnitude of the US dollar, usually all you need is to be able to store multiples of 10^-2, so it doesn't really matter that 1/3 can't be represented.

The problem with floats and doubles is that the vast majority of money-like numbers don't have an exact representation as an integer times a power of 2. In fact, the only multiples of 0.01 between 0 and 1 (which are significant when dealing with money because they're integer cents) that can be represented exactly as an IEEE-754 binary floating-point number are 0, 0.25, 0.5, 0.75 and 1. All the others are off by a small amount. As an analogy to the 0.333333 example, if you take the floating-point value for 0.1 and you multiply it by 10, you won't get 1.

Representing money as a double or float will probably look good at first as the software rounds off the tiny errors, but as you perform more additions, subtractions, multiplications and divisions on inexact numbers, errors will compound and you'll end up with values that are visibly not accurate. This makes floats and doubles inadequate for dealing with money, where perfect accuracy for multiples of base 10 powers is required.

A solution that works in just about any language is to use integers instead, and count cents. For instance, 1025 would be $10.25. Several languages also have built-in types to deal with money. Among others, Java has the BigDecimal class, and C# has the decimal type.

Once you have you date parsed, I use this utility function to add hours, minutes or seconds:

public class DateTimeUtils {
    private static final long ONE_HOUR_IN_MS = 3600000;
    private static final long ONE_MIN_IN_MS = 60000;
    private static final long ONE_SEC_IN_MS = 1000;

    public static Date sumTimeToDate(Date date, int hours, int mins, int secs) {
        long hoursToAddInMs = hours * ONE_HOUR_IN_MS;
        long minsToAddInMs = mins * ONE_MIN_IN_MS;
        long secsToAddInMs = secs * ONE_SEC_IN_MS;
        return new Date(date.getTime() + hoursToAddInMs + minsToAddInMs + secsToAddInMs);
    }
}

Be careful when adding long periods of time, 1 day is not always 24 hours (daylight savings-type adjustments, leap seconds and so on), Calendar is recommended for that.

That's a great question. I think @Diederik has a good answer, although it's unfortunate that Cocoa doesn't have a mechanism for exactly what you want to do.

NSInputStream allows you to read chunks of N bytes (very similar to java.io.BufferedReader), but you have to convert it to an NSString on your own, then scan for newlines (or whatever other delimiter) and save any remaining characters for the next read, or read more characters if a newline hasn't been read yet. (NSFileHandle lets you read an NSData which you can then convert to an NSString, but it's essentially the same process.)

Apple has a Stream Programming Guide that can help fill in the details, and this SO question may help as well if you're going to be dealing with uint8_t* buffers.

If you're going to be reading strings like this frequently (especially in different parts of your program) it would be a good idea to encapsulate this behavior in a class that can handle the details for you, or even subclassing NSInputStream (it's designed to be subclassed) and adding methods that allow you to read exactly what you want.

For the record, I think this would be a nice feature to add, and I'll be filing an enhancement request for something that makes this possible. :-)

Edit: Turns out this request already exists. There's a Radar dating from 2006 for this (rdar://4742914 for Apple-internal people).

The following code creates a table with 2 column as a primary key in SQLite.

SOLUTION:

CREATE TABLE IF NOT EXISTS users (
    id TEXT NOT NULL, 
    name TEXT NOT NULL,

    PRIMARY KEY (id, name)

This is not difficult to achieve, but you need to use the javascript onmouseover function. Pseudoscript:

<div class="section ">

<div class="image"><img src="myImage.jpg" onmouseover=".layer {border: 1px solid black;} .image {border: 1px solid black;}" /></div>

<div class="layer">Lorem Ipsum</div>

</div>

Use your own colors. You can also reference javascript functions in the mouseover command.

In my case reason was too stupid :

I had a Constant.h file where I had macros defined. I thought of doing NSString there. and did this :

NSString const *kGreenColor = @"#00C34E";

this caused the problem of Duplicate Symbols for Architecture arm64 and Linker command failed with exit code 1. Removing const NSString line worked for me.

If you are on a OS X, this probably has nothing to do with the sed command. On the OSX version of sed, the -i option expects an extension argument so your command is actually parsed as the extension argument and the file path is interpreted as the command code.

Try adding the -e argument explicitly and giving '' as argument to -i:

find ./ -type f -exec sed -i '' -e "s/192.168.20.1/new.domain.com/" {} \;

See this.

I guess you could use curl and wget, but since Oracle requires you to check of some checkmarks this will be painfull to emulate with the tools mentioned. You would have to download the page with the license agreement and from looking at it figure out what request is needed to get to the actual download.

Of course you could simply start a browser, but this might not qualify as 'from the command line'. So you might want to look into lynx, a text based browser.

Although the accepted answer is correct but if you are just trying to upload your image to cloudinary, there's a better way:

Map upload = cloudinary.uploader().upload(multipartFile.getBytes(), ObjectUtils.emptyMap());

Where multipartFile is your org.springframework.web.multipart.MultipartFile.

Good news! Swift 4.2 (Xcode 10) finally provides CommonCrypto!

Just add import CommonCrypto in your swift file.

To really be universal, I'm using this:

$protocol = (!empty($_SERVER['HTTPS']) && $_SERVER['HTTPS'] !== 'off' 
    || $_SERVER['SERVER_PORT'] == 443) ? 'https://' : 'http://';
header('Location: '.$protocol.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
exit;

I like $_SERVER['REQUEST_URI'] because it respects mod_rewrite and/or any GET variables.

Hey guys, I had heaps of trouble with this yesterday. I went through the whole process a few times, requesting a new certificate request from the authority with the assistant, clearing out everything in the portal, uploading the certificate, creating a new profile and downloading everything. No dice.

However, check this out.

First up clear out all the certificates on the portal to start fresh.

After creating the new certificate request with the assistant, press "Show in Finder", and double click that bad boy. You should get a popup for the Certificate Assistant with a screen showing "Please specify the issuing Certificate Authority", etc. If you don't, just close it and double click again. Now just proceed through the dialog choosing "Request a certificate from an existing CA" - Continue Request is "Saved to disk" - Continue Save it where ever you like, even override the file.

At the end you should see the magic "Creating key pair"

Run over to the KeyChain access and you'll see your keys in there! Upload this certificate to the apple portal and then go through their wizard as normal, everything should work great now.

Stackpanel doesn't have built in scrolling mechanism but you can always wrap the StackPanel in a ScrollViewer

<ScrollViewer VerticalScrollBarVisibility="Auto">
  <StackPanel ... />
</ScrollViewer>

Below solution perfectly works for spring boot application.

Controller:

@GetMapping("user/getAllInactiveUsers")
List<User> getAllInactiveUsers(@RequestParam("date") @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date dateTime) {
    return userRepository.getAllInactiveUsers(dateTime);
}

So in the caller (in my case its a web flux), we need to pass date time in this("yyyy-MM-dd HH:mm:ss") format.

Caller Side:

public Flux<UserDto> getAllInactiveUsers(String dateTime) {
    Flux<UserDto> userDto = RegistryDBService.getDbWebClient(dbServiceUrl).get()
            .uri("/user/getAllInactiveUsers?date={dateTime}", dateTime).retrieve()
            .bodyToFlux(User.class).map(UserDto::of);
    return userDto;
}

Repository:

@Query("SELECT u from User u  where u.validLoginDate < ?1 AND u.invalidLoginDate < ?1 and u.status!='LOCKED'")
List<User> getAllInactiveUsers(Date dateTime);

Cheers!!

Just type git init into your command line and press enter. Then run your command again, you probably were running git remote add origin [your-repository].

That should work, if it doesn't, just let me know.

Another option is to use KernelReg in statsmodels:

from statsmodels.nonparametric.kernel_regression import KernelReg
import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2

# The third parameter specifies the type of the variable x;
# 'c' stands for continuous
kr = KernelReg(y,x,'c')
plt.plot(x, y, '+')
y_pred, y_std = kr.fit(x)

plt.plot(x, y_pred)
plt.show()

I want to mention something that caught me first when I was trying to adapt a SpriteKit-based app to avoid the round edges and "notch" of the new iPhone X, as suggested by the latest Human Interface Guidelines: The new property safeAreaLayoutGuide of UIView needs to be queried after the view has been added to the hierarchy (for example, on -viewDidAppear:) in order to report a meaningful layout frame (otherwise, it just returns the full screen size).

From the property's documentation:

The layout guide representing the portion of your view that is unobscured by bars and other content. When the view is visible onscreen, this guide reflects the portion of the view that is not covered by navigation bars, tab bars, toolbars, and other ancestor views. (In tvOS, the safe area reflects the area not covered the screen's bezel.) If the view is not currently installed in a view hierarchy, or is not yet visible onscreen, the layout guide edges are equal to the edges of the view.

(emphasis mine)

If you read it as early as -viewDidLoad:, the layoutFrame of the guide will be {{0, 0}, {375, 812}} instead of the expected {{0, 44}, {375, 734}}

for Python and Swagger example:

import requests
base_url = 'https://petstore.swagger.io/v2'
def store_order(uid):
    api_url = f"{base_url}/store/order"
    api_data = {
        'id':uid,
        "petId": 0,
        "quantity": 0,
        "shipDate": "2020-04-08T07:56:05.832Z",
        "status": "placed",
        "complete": "true"
        }
    # is a kind of magic..
    r = requests.post(api_url, json=api_data)
    return r
print(store_order(0).content)    

Most important string with MIME type: r = requests.post(api_url, json=api_data)

You can't insert the values into timestamp column explicitly. It is auto-generated. Do not use this column in your insert statement. Refer http://msdn.microsoft.com/en-us/library/ms182776(SQL.90).aspx for more details.

You could use a datetime instead of a timestamp like this:

create table demo (
    ts datetime
)

insert into demo select current_timestamp

select ts from demo

Returns:

2014-04-04 09:20:01.153

If i am correct in believing that you are adding a variable to the array but when you change that variable outside of the array, it also changes inside the array but you don't want it to then it is a really simple solution.

When you are saving the variable to the array you should turn it into a string by simply putting str(variablename). For example:

array.append(str(variablename))

Using this method your code should look like this:

arrayList = []
for x in allValues:
    result = model(x)
    arrayList.append(str(wM))        #this is the only line that is changed.
    wM.reset()

after cloning a fork you have to explicitly add a remote upstream, with git add remote "the original repo you forked from". This becomes your upstream, you mostly fetch and merge from your upstream. Any other business such as pushing from your local to upstream should be done using pull request.

You can override the default implementation of console.log()

(function () {
    var old = console.log;
    var logger = document.getElementById('log');
    console.log = function (message) {
        if (typeof message == 'object') {
            logger.innerHTML += (JSON && JSON.stringify ? JSON.stringify(message) : message) + '<br />';
        } else {
            logger.innerHTML += message + '<br />';
        }
    }
})();

I know this is an old post, but I really hate that there is only one answer here that suggests not mixing html and php. Instead of mixing content one should use template systems, or create a basic template system themselves.

In the php

<?php 
  $var1 = 'Alice'; $var2 = 'apples'; $var3 = 'lunch'; $var4 = 'Bob';

  if ($var1 == 'Alice') {
    $html = file_get_contents('/path/to/file.html'); //get the html template
    $template_placeholders = array('##variable1##', '##variable2##', '##variable3##', '##variable4##'); // variable placeholders inside the template
    $template_replace_variables = array($var1, $var2, $var3, $var4); // the variables to pass to the template
    $html_output = str_replace($template_placeholders, $template_replace_variables, $html); // replace the placeholders with the actual variable values.
  }

  echo $html_output;
?>

In the html (/path/to/file.html)

<p>##variable1## ate ##variable2## for ##variable3## with ##variable4##.</p>

The output of this would be:

Alice ate apples for lunch with Bob.

Outline: Create two elements: a slider/switch and a trough as a parent of the slider. To toggle the state, switch the slider element between an "on" and an "off" class. In the style for one class, set "left" to 0 and leave "right" the default; for the other class, do the opposite:

<style type="text/css">
.toggleSwitch {
    width: ...;
    height: ...;
    /* add other styling as appropriate to position element */
    position: relative;
}
.slider {
    background-image: url(...);
    position: absolute;
    width: ...;
    height: ...;
}
.slider.on {
    right: 0;
}
.slider.off {
    left: 0;
}
</style>
<script type="text/javascript">
function replaceClass(elt, oldClass, newClass) {
    var oldRE = RegExp('\\b'+oldClass+'\\b');
    elt.className = elt.className.replace(oldRE, newClass);
}
function toggle(elt, on, off) {
    var onRE = RegExp('\\b'+on+'\\b');
    if (onRE.test(elt.className)) {
        elt.className = elt.className.replace(onRE, off);
    } else {
        replaceClass(elt, off, on);
    }
}
</script>
...
<div class="toggleSwitch" onclick="toggle(this.firstChild, 'on', 'off');"><div class="slider off" /></div>

Alternatively, just set the background image for the "on" and "off" states, which is a much easier approach than mucking about with positioning.

For the benefit of anyone who might believe e.g. that doing aset.add() in a loop would have performance competitive with doing aset.update(), here's an example of how you can test your beliefs quickly before going public:

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 294 usec per loop

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 950 usec per loop

>\python27\python -mtimeit -s"it=xrange(10000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 458 usec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a.update(it)"
1000 loops, best of 3: 598 usec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "for i in it:a.add(i)"
1000 loops, best of 3: 1.89 msec per loop

>\python27\python -mtimeit -s"it=xrange(20000);a=set(xrange(100))" "a |= set(it)"
1000 loops, best of 3: 891 usec per loop

Looks like the cost per item of the loop approach is over THREE times that of the update approach.

Using |= set() costs about 1.5x what update does but half of what adding each individual item in a loop does.

do use the links above. If you run into error "This update is not applicable to your computer. " then make sure you are in fact using the right file for your os. for example i tried running windows 2012 server from that link on windows 7 service pack 1 and I got the above error so be sure to use the right zip. If you don't know which os you have then go to start and system and it should pop right up This should be self explanatory but

I stopped counting how many times over the years I opened this question with hopes to have seen this implemented.

Well, finally we can all rejoice! Microsoft is going to introduce this in their upcoming C# 8 release.

So instead of doing this...

public static class IntExtensions
{
   public static bool Even(this int value)
   {
        return value % 2 == 0;
   }
}

We'll be finally able to do it like so...

this is a simple alternative that gives all responses, Fullname, Path, filename.

Dim FilePath, FileOnly, PathOnly As String

FilePath = ThisWorkbook.FullName
FileOnly = ThisWorkbook.Name
PathOnly = Left(FilePath, Len(FilePath) - Len(FileOnly))

From iOS 6 and later UITextAlignment is deprecated. use NSTextAlignment

myLabel.textAlignment = NSTextAlignmentCenter;

Swift Version from iOS 6 and later

myLabel.textAlignment = .center

Now android studio is provide a plugin Image Asset, which will be generate icon in all required drawbale folder

Image Asset Studio helps you create various types of icons at different densities and shows you exactly where they'll be placed in your project. It includes tools for adjusting your icons and adding backdrops, all while displaying the result in a preview pane, so they appear exactly as you intended. These tools can dramatically streamline the icon design and import process.

You can access Image Asset by click new> click on Image Asset option and it will be show window like this :-

#include <iostream>
int main()
{
    int v[100] = {5,14,2,4,6};
    int n = 5;
    int mic = v[0];
    for(int i = 0; i != n; ++i)
    {
        if(v[i] < mic)
        mic = v[i];
    }
    std:cout << mic << std::endl;;
}

array_map seems good for this too

$codes = array('tn','us','fr');
$names = array('Tunisia','United States','France');

array_map(function ($code, $name) {
    echo '<option value="' . $code . '">' . $name . '</option>';
}, $codes, $names);

Other benefits are:

• If one array is shorter than the other, the callback receive null values to fill in the gap.

• You can use more than 2 arrays to iterate through.

We had a component enclosed in the curly braces i.e. { and }:

const SomeComponent = () => {<div> Some Component Page </div>}

Replacing them with the round brackets i.e. ( and ) fixed the issue:

const SomeComponent = () => (<div> Some Component Page </div>)

Most likely You are doing it wrong.

Java 8 Optional is not meant to be used in this manner. It is usually only reserved for terminal stream operations that may or may not return a value, like find for example.

In your case it might be better to first try to find a cheap way to filter out those items that are resolvable and then get the first item as an optional and resolve it as a last operation. Better yet - instead of filtering, find the first resolvable item and resolve it.

things.filter(Thing::isResolvable)
      .findFirst()
      .flatMap(this::resolve)
      .get();

Rule of thumb is that you should strive to reduce number of items in the stream before you transform them to something else. YMMV of course.

When you develop an emulator you are interpreting the processor assembly that the system is working on (Z80, 8080, PS CPU, etc.).

You also need to emulate all peripherals that the system has (video output, controller).

You should start writing emulators for the simpe systems like the good old Game Boy (that use a Z80 processor, am I not not mistaking) OR for C64.

String a = "jklmn489pjro635ops";

int sum = 0;

String num = "";

boolean notFirst = false;

for (char c : a.toCharArray()) {

    if (Character.isDigit(c)) {
        sum = sum + Character.getNumericValue(c);
        System.out.print((notFirst? " + " : "") + c);
        notFirst = true;
    }
}

System.out.println(" = " + sum);

You want the String.strip(s[, chars]) function, which will strip out whitespace characters or whatever characters (such as '\n') you specify in the chars argument.

See http://docs.python.org/release/2.3/lib/module-string.html

You can use the zfill() method to pad a string with zeros:

In [3]: str(1).zfill(2)
Out[3]: '01'

The issue is incompatible web application version with the targeted server. So project facets needs to be changed. In most of the cases the "Dynamic Web Module" property. This should be the value of the servlet-api version supported by the server.

In my case,

I tried changing the web_app value in web.xml. It did not worked.

I tried changing the project facet by right clicking on project properties(as mentioned above), did not work.

What worked is: Changing "version" value as in jst.web to right version from

org.eclipse.wst.common.project.facet.core.xml file. This file is present in the .setting folder under your project root directory.

This happens because LatLngBounds() does not take two arbitrary points as parameters, but SW and NE points

use the .extend() method on an empty bounds object

var bounds = new google.maps.LatLngBounds();
bounds.extend(myPlace);
bounds.extend(Item_1);
map.fitBounds(bounds);

If you just have a static svg string you want to include, you can use dangerouslySetInnerHTML:

render: function() {
    return <span dangerouslySetInnerHTML={{__html: "<svg>...</svg>"}} />;
}

and React will include the markup directly without processing it at all.

max(ozone$Ozone, na.rm = TRUE) should do the trick. Remember to include the na.rm = TRUE or else R will return NA.

// Convert String to Integer

// String s = "fred";  // use this if you want to test the exception below


String s = "100"; 
try
{
  // the String to int conversion happens here
  int i = Integer.parseInt(s.trim());

  // print out the value after the conversion
  System.out.println("int i = " + i);
}
catch (NumberFormatException nfe)
{
  System.out.println("NumberFormatException: " + nfe.getMessage());
}

Check if your Java JDK is installed correctly

dpkg --list | grep -i jdk

If not, install JDK

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update && sudo apt-get install oracle-java8-installer

After the installation you have to enable the jdk

update-alternatives --display java

Check if Ubuntu uses Java JDK 8

java -version

If all went right the answer should be something like this:

java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

Check what compiler is used

javac -version

It should show something like this

javac 1.8.0_91

Finally, add JAVA_HOME to the environment variable

Edit /etc/environment and add JAVA_HOME=/usr/lib/jvm/java-8-oracle to the end of the file

sudo nano /etc/environment

Append to the end of the file

JAVA_HOME=/usr/lib/jvm/java-8-oracle

You will then have to reboot, you can do this from the terminal with:

sudo reboot

In case you want to remove the JDK

sudo apt-get remove oracle-java8-installer

After long search and hours of trying this is the simplest code i could make:

ShapeDrawable border = new ShapeDrawable(new RectShape());
border.getPaint().setStyle(Style.STROKE);
border.getPaint().setColor(Color.BLACK);
tv.setBackground(border);
content.addView(tv);

tv is a TextView with a simple text and content is my container (LinearLayout in this Case). That's a little easier.

The following simply returns 4 as an answer. When you replace the add expressions for strings it returns the first string.

Function StartingMain {
  $a = 1 + 3
  $b = 2 + 5
  $c = 3 + 7
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b
}

StartingEnd(StartingMain)

This can also be done for an array. The example below will return "Text 2"

Function StartingMain {
  $a = ,@("Text 1","Text 2","Text 3")
  Return $a
}

Function StartingEnd($b) {
  Write-Host $b[1]
}

StartingEnd(StartingMain)

Note that you have to call the function below the function itself. Otherwise, the first time it runs it will return an error that it doesn't know what "StartingMain" is.

>>> a = 'ZENOVW'
>>> b = sorted(a)
>>> print b
['E', 'N', 'O', 'V', 'W', 'Z']

sorted returns a list, so you can make it a string again using join:

>>> c = ''.join(b)

which joins the items of b together with an empty string '' in between each item.

>>> print c
'ENOVWZ'

recently i wanted to know the assembly of each functions in a program
this is how i did it.

$ gcc main.c                      // main.c source file
$ gdb a.exe                       // gdb a.out in linux
  (gdb) disass main               // note here main is a function
                                  // similary it can be done for other functions

Take a look at WinRun4J. It's windows only but that's because unix has executable scripts that look (to the user) like bins. You can also easily modify WinRun4J to compile on unix.

It does require a config file, but again, recompile it with hard-coded options and it works like a config-less exe.

Because break can only be used inside a loop. It is used to break out of a loop (stop the loop).

This works also in Python 3.x and centers the window on screen:

from tkinter import *

app = Tk()
app.eval('tk::PlaceWindow . center')
app.mainloop()

In my case I got this error because of a line

<script src="#"></script> 

Chrome tried to interpret the current HTML file then as javascript.

Not sure why this thread got necroed; but here is a 2014 approved answer, which should be far faster:

import numpy as np

data = np.random.rand(100)
bins = 10
slices = np.linspace(0, 100, bins+1, True).astype(np.int)
counts = np.diff(slices)

mean = np.add.reduceat(data, slices[:-1]) / counts
print mean

I added dataType as json and made the response as json:

PHP

echo json_encode(array('success'=>$res)); //send the response as json **use this instead of echo $res in your php file**

JavaScript

  var ajaxSubmit = function(formE1) {

        var password = $.trim($('#employee_password').val());    
        $.ajax({
            type: "POST",
            async: "false",
            url: "checkpass.php",
            data: "password="+password,
            dataType:'json',  //added this so the response is in json
            success: function(result) {
                var arr=result.success;
                if(arr == "Successful")
                {    return true;
                }
                else
                {    return false;
                }
            }
        });

  return false
}

You can use date filter to convert in date and display in specific format.

In .ts file (typescript):

let dateString = '1968-11-16T00:00:00' 
let newDate = new Date(dateString);

In HTML:

{{dateString |  date:'MM/dd/yyyy'}}

Below are some formats which you can implement :

Backend:

public todayDate = new Date();

HTML :

<select>
<option value=""></option>
<option value="MM/dd/yyyy">[{{todayDate | date:'MM/dd/yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy">[{{todayDate | date:'EEEE, MMMM d, yyyy'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm a'}}]</option>
<option value="EEEE, MMMM d, yyyy h:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy h:mm:ss a'}}]</option>
<option value="MM/dd/yyyy h:mm a">[{{todayDate | date:'MM/dd/yyyy h:mm a'}}]</option>
<option value="MM/dd/yyyy h:mm:ss a">[{{todayDate | date:'MM/dd/yyyy h:mm:ss a'}}]</option>
<option value="MMMM d">[{{todayDate | date:'MMMM d'}}]</option>   
<option value="yyyy-MM-ddTHH:mm:ss">[{{todayDate | date:'yyyy-MM-ddTHH:mm:ss'}}]</option>
<option value="h:mm a">[{{todayDate | date:'h:mm a'}}]</option>
<option value="h:mm:ss a">[{{todayDate | date:'h:mm:ss a'}}]</option>      
<option value="EEEE, MMMM d, yyyy hh:mm:ss a">[{{todayDate | date:'EEEE, MMMM d, yyyy hh:mm:ss a'}}]</option>
<option value="MMMM yyyy">[{{todayDate | date:'MMMM yyyy'}}]</option> 
</select>

There's a I/O library available, but if it's available depends on your scripting host (assuming you've embedded lua somewhere). It's available, if you're using the command line version. The complete I/O model is most likely what you're looking for.

Make sure you saved the file as JavaScript. Un check 'Hide extensions for all known type' check box in Folder Options window will show you the correct file extension(Folder>>view>>Option).

Firstly, the PHP documentation has some excellent information on sessions.

Secondly, you will need some way to store the credentials for each user of your website (e.g. a database). It is a good idea not to store passwords as human-readable, unencrypted plain text. When storing passwords, you should use PHP's crypt() hashing function. This means that if any credentials are compromised, the passwords are not readily available.

Most log-in systems will hash/crypt the password a user enters then compare the result to the hash in the storage system (e.g. database) for the corresponding username. If the hash of the entered password matches the stored hash, the user has entered the correct password.

You can use session variables to store information about the current state of the user - i.e. are they logged in or not, and if they are you can also store their unique user ID or any other information you need readily available.

To start a PHP session, you need to call session_start(). Similarly, to destroy a session and its data, you need to call session_destroy() (for example, when the user logs out):

// Begin the session
session_start();

// Use session variables
$_SESSION['userid'] = $userid;

// E.g. find if the user is logged in
if($_SESSION['userid']) {
    // Logged in
}
else {
    // Not logged in
}

// Destroy the session
if($log_out)
    session_destroy();

I would also recommend that you take a look at this. There's some good, easy to follow information on creating a simple log-in system there.

To access a single value you can use the method iat that is much faster than iloc:

df['Btime'].iat[0]

Output:

1.2

string RemoveChar(string str, char c) 
{
   string result;
   for (size_t i = 0; i < str.size(); i++) 
   {
          char currentChar = str[i];
          if (currentChar != c)
              result += currentChar;
   }
       return result;
}

This is how I did it.

Or you could do as Antoine mentioned:

See this question which answers the same problem. In your case:

#include <algorithm>
str.erase(std::remove(str.begin(), str.end(), 'a'), str.end());

You can also receive a 406 response when invalid cookies are stored or referenced in the browser - for example, when running a Rails server in Dev mode locally.

If you happened to run two different projects on the same port, the browser might reference a cookie from a different localhost session.

This has happened to me...tripped me up for a minute. Looking in browser > Developer Mode > Network showed it.

Since @Jonathan's answer still consisted of some bugs, I made an improved version. I overwrote the toString() method for debugging purposes, be sure to change it accordingly to your data.

Some additional informations: Do not use addChildren() and setParent() together. You'll end up having two references as setParent() already updates the children=>parent relationship.

SELECT TIMESTAMPDIFF(HOUR,NOW(),'2013-05-15 10:23:23')

You could use a Data URI to supply the image data, for example:

<svg xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

<image width="20" height="20" xlink:href="data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>

</svg>

The image will go through all normal svg transformations.

But this technique has disadvantages, for example the image will not be cached by the browser
