Yes there is:

std::vector<int> vec(SIZE, 0);

Use a vector instead of a dynamically allocated array. Benefits include not having to bother with explicitely deleting the array (it is deleted when the vector goes out of scope) and also that the memory is automatically deleted even if there is an exception thrown.

Edit: To avoid further drive-by downvotes from people that do not bother to read the comments below, I should make it more clear that this answer does not say that vector is always the right answer. But it sure is a more C++ way than "manually" making sure to delete an array.

Now with C++11, there is also std::array that models a constant size array (vs vector that is able to grow). There is also std::unique_ptr that manages a dynamically allocated array (that can be combined with initialization as answered in other answers to this question). Any of those are a more C++ way than manually handling the pointer to the array, IMHO.

--save-dev means "needed only when developing"

• e.g. the final users using your package will not want/need/care about what testing suite you used; they will only want packages that are absolutely required to run your code in a production environment. This flag marks what is needed when developing vs production.

Replace implementation 'com.android.support:appcompat-v7:28.0.0-beta01' with

implementation 'com.android.support:appcompat-v7:28.0.0-alpha1' 

in build.gradle (Module:app). It fixed my red mark in Android Studio 3.1.3

sequenceName is the name of the sequence in the DB. This is how you specify a sequence that already exists in the DB. If you go this route, you have to specify the allocationSize which needs to be the same value that the DB sequence uses as its "auto increment".

Usage:

@GeneratedValue(generator="my_seq")
@SequenceGenerator(name="my_seq",sequenceName="MY_SEQ", allocationSize=1)

If you want, you can let it create a sequence for you. But to do this, you must use SchemaGeneration to have it created. To do this, use:

@GeneratedValue(strategy=GenerationType.SEQUENCE)

Also, you can use the auto-generation, which will use a table to generate the IDs. You must also use SchemaGeneration at some point when using this feature, so the generator table can be created. To do this, use:

@GeneratedValue(strategy=GenerationType.AUTO)

With Android Studio, try this:

//region VARIABLES
private String _sMyVar1;
private String _sMyVar2;
//endregion

Careful : no blank line after //region ...

And you will get:

Guava provides the adapter you want as Int.asList(). There is an equivalent for each primitive type in the associated class, e.g., Booleans for boolean, etc.

int foo[] = {1,2,3,4,5,6,7,8,9,0};
Iterable<Integer> fooBar = Ints.asList(foo);
for(Integer i : fooBar) {
    System.out.println(i);
}

The suggestions above to use Arrays.asList won't work, even if they compile because you get an Iterator<int[]> rather than Iterator<Integer>. What happens is that rather than creating a list backed by your array, you created a 1-element list of arrays, containing your array.

Had the same error type, where exactly the same error message in logcat was displayed. I needed to make changes in the Java Build Path located under Project->Properties. I had included Google Maps related libraries like android-support-v4.jar and google-play-services.jar; however I was missing including these on the 'Build class path' in the 'Order and Export' option menu. Maybe the error lies here.

Try including libraries to the build class path.

The order of which the classes are built might also trigger the error, so my advice is also to try to rearrange the order of the building path. The error disappeared when I used the following order: 'my_project_name/src'->'my_project_name/gen'->'Android Private Libraries'. The last unit contains the jar files mentioned earlier.

Your compile SDK version must match the support library's major version.

Since you are using version 23 of the support library, you need to compile against version 23 of the Android SDK.

Alternatively you can continue compiling against version 22 of the Android SDK by switching to the latest support library v22.

A Context represents your environment. It represents the state surrounding where you are in your system.

For example, in web programming in Java, you have a Request, and a Response. These are passed to the service method of a Servlet.

A property of the Servlet is the ServletConfig, and within that is a ServletContext.

The ServletContext is used to tell the servlet about the Container that the Servlet is within.

So, the ServletContext represents the servlets environment within its container.

Similarly, in Java EE, you have EBJContexts that elements (like session beans) can access to work with their containers.

Those are two examples of contexts used in Java today.

Edit --

You mention Android.

Look here: http://developer.android.com/reference/android/content/Context.html

You can see how this Context gives you all sorts of information about where the Android app is deployed and what's available to it.

It is safer to run through bool first. This is easily done:

>>> sum(map(bool,[True, True, False, False, False, True]))
3

Then you will catch everything that Python considers True or False into the appropriate bucket:

>>> allTrue=[True, not False, True+1,'0', ' ', 1, [0], {0:0}, set([0])]
>>> list(map(bool,allTrue))
[True, True, True, True, True, True, True, True, True]

If you prefer, you can use a comprehension:

>>> allFalse=['',[],{},False,0,set(),(), not True, True-1]
>>> [bool(i) for i in allFalse]
[False, False, False, False, False, False, False, False, False]

string t = DateTime.Now.ToString("h/m/s tt");
string t2 = DateTime.Now.ToString("hh:mm:ss tt");
string d = DateTime.Now.ToString("MM/dd/yy");

If you try pasting into Word-Pad, Notepad++ or Word you wouldn't have this issue. To copy the cell value as pure text, to achieve what you describe you have to use a macro:

In the workbook where you want this to apply (or in your Personal.xls if you want to use across several workbooks), place the following code in a standard module:

Code:

Sub CopyCellContents()
'create a reference in the VBE to Microsft Forms 2.0 Lib
' do this by (in VBA editor) clicking tools - > references and then ticking "Microsoft Forms 2.0 Library"
Dim objData As New DataObject
Dim strTemp As String
strTemp = ActiveCell.Value
objData.SetText (strTemp)
objData.PutInClipboard
End Sub

To add a standard module to your project (workbook), open up the VBE with Alt+F11 and then right-click on your workbook in the top left Project Window and select Insert>Module. Paste the code into the code module window which will open on the right.

Back in Excel, go Tools>Macro>Macros and select the macro called "CopyCellContents" and then choose Options from the dialog. Here you can assign the macro to a shortcut key (eg like CTRL+C for normal copy) - I used CTRL+Q.

Then, when you want to copy a single cell over to Notepad/wherever, just do Ctrl+q (or whatever you chose) and then do a CTRL+V or Edit>Paste in your chosen destination.

My answer is copied (with a few additions) from: here

EDIT: (from comments)

If you don't find Microsoft Forms 2.0 Library in the references list, You can try

• looking for FM20.DLL instead (thanks @Peter Smallwood)
• clicking Browse and selecting C:\Windows\System32\FM20.dll (32 bit Windows) (thanks @JWhy)
• clicking Browse and selecting C:\Windows\SysWOW64\FM20.dll (on 64-bit)

Since you are on 10g, you could potentially use the ORA_ROWSCN pseudocolumn. That gives you an upper bound of the last SCN (system change number) that caused a change in the row. Since this is an increasing sequence, you could store off the maximum ORA_ROWSCN that you've seen and then look only for data with an SCN greater than that.

By default, ORA_ROWSCN is actually maintained at the block level, so a change to any row in a block will change the ORA_ROWSCN for all rows in the block. This is probably quite sufficient if the intention is to minimize the number of rows you process multiple times with no changes if we're talking about "normal" data access patterns. You can rebuild the table with ROWDEPENDENCIES which will cause the ORA_ROWSCN to be tracked at the row level, which gives you more granular information but requires a one-time effort to rebuild the table.

Another option would be to configure something like Change Data Capture (CDC) and to make your OCI application a subscriber to changes to the table, but that also requires a one-time effort to configure CDC.

Like Cheeso said:

You don't need the directory on your path. You could put it on your path, but you don't NEED to do that. If you are calling regasm rarely, or calling it from a batch file, you may find it is simpler to just invoke regasm via the fully-qualified pathname on the exe, eg:

%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\regasm.exe MyAssembly.dll

You could use predefined utility type Record<Keys, Type> :

const obj: Record<string, string> = {
  property: "value",
};

It allows to specify keys for your object literal:

type Keys = "prop1" | "prop2"

const obj: Record<Keys, string> = {
  prop1: "Hello",
  prop2: "Aloha",
  something: "anything" // TS Error: Type '{ prop1: string; prop2: string; something: string; }' is not assignable to type 'Record<Keys, string>'.
                        //   Object literal may only specify known properties, and 'something' does not exist in type 'Record<Keys, string>'.
};

And a type for the property value:

type Keys = "prop1" | "prop2"
type Value = "Hello" | "Aloha"

const obj1: Record<Keys, Value> = {
  prop1: "Hello",
  prop2: "Hey", // TS Error: Type '"Hey"' is not assignable to type 'Value'.
};

I do not have an @github.com address

You don't have to: the @ is the separator between the username:password and the domain.
It is not an email address.

A full GitHub https url would be:

https://username:[email protected]/username/reponame.git

Without the password (which would then be asked on the command line), that would gave:

https://[email protected]/username/reponame.git

But again, [email protected] isn't an email address, just the first part of the credentials.

Make sure the case of your username and reponame is correct: it is case sensitive.

Note that you can store and encrypt your credentials in a .netrc.gpg (or _netrc.gpg on Windows) if you don't want to put said credentials in clear in the url.
See "Is there a way to skip password typing when using https://github".

One reason can be that the IEnumerable may contain an unknown number of items. Some implementations produce the list of items as you iterate over it (see yield for samples). That does not work very well with accessing items using an index. which would require you to know that there are at least that many items in the list.

I met this problem with typescript but forgot to add ts and tsx suffix to resolve entry.

module.exports = {
  ...
  resolve: {
    extensions: ['.js', '.jsx', '.ts', '.tsx'],
  },
};

This does the job for me

It's because any iterable can be joined (e.g, list, tuple, dict, set), but its contents and the "joiner" must be strings.

For example:

'_'.join(['welcome', 'to', 'stack', 'overflow'])
'_'.join(('welcome', 'to', 'stack', 'overflow'))

'welcome_to_stack_overflow'

Using something other than strings will raise the following error:

TypeError: sequence item 0: expected str instance, int found

The first value is the precision and the second is the scale, so 18,0 is essentially 18 digits with 0 digits after the decimal place. If you had 18,2 for example, you would have 18 digits, two of which would come after the decimal...

example of 18,2: 1234567890123456.12

There is no functional difference between numeric and decimal, other that the name and I think I recall that numeric came first, as in an earlier version.

And to answer, "can I add (-10) in that column?" - Yes, you can.

If you have loads of re-directs to create, having loads of virtual directories over the places is a nightmare to maintain. You could try using ISAPI redirect an IIS extension. Then all you re-directs are managed in one place.

http://www.isapirewrite.com/docs/

It allows also you to match patterns based on reg ex expressions etc. I've used where I've had to re-direct 100's of pages and its saved a lot of time.

You are probably using Console.WriteLine for printing the array.

int[] array = new int[] { 1, 2, 3 };
foreach(var item in array)
{
    Console.WriteLine(item.ToString());
}

If you don't want to have every item on a separate line use Console.Write:

int[] array = new int[] { 1, 2, 3 };
foreach(var item in array)
{
    Console.Write(item.ToString());
}

or string.Join<T> (in .NET Framework 4 or later):

int[] array = new int[] { 1, 2, 3 };
Console.WriteLine(string.Join(",", array));

There's a difference between additive colors (http://en.wikipedia.org/wiki/Additive_color) and subtractive colors (http://en.wikipedia.org/wiki/Subtractive_color).

With additive colors, the more you add, the brighter the colors become. This is because they are emitting light. This is why the day light is (more or less) white, since the Sun is emitting in almost all the visible wavelength spectrum.

On the other hand, with subtractive colors the more colors you mix, the darker the resulting color. This is because they are reflecting light. This is also why the black colors get hotter quickly, because it absorbs (almost) all light energy and reflects (almost) none.

Specifically to your question, it depends what medium you are working on. Traditionally, additive colors (RGB) are used because the canon for computer graphics was the computer monitor, and since it's emitting light, it makes sense to use the same structure for the graphic card (the colors are shown without conversions). However, if you are used to graphic arts and press, subtractive color model is used (CMYK). In programs such as Photoshop, you can choose to work in CMYK space although it doesn't matter what color model you use: the primary colors of one group are the secondary colors of the second one and viceversa.

P.D.: my father worked at graphic arts, this is why i know this... :-P

I just use a bit of jQuery/javascript:

html:

<h1>Don't Print</h1>

<a data-target="#myModal" role="button" class="btn" data-toggle="modal">Launch modal</a>

<div class="modal fade hide" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel"      aria-hidden="true">
  <div class="modal-header">
    <button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
     <h3 id="myModalLabel">Modal to print</h3>
  </div>
  <div class="modal-body">
    <p>Print Me</p>
  </div>
  <div class="modal-footer">
    <button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
    <button class="btn btn-primary" id="printButton">Print</button>
  </div>
</div>

js:

$('#printButton').on('click', function () {
    if ($('.modal').is(':visible')) {
        var modalId = $(event.target).closest('.modal').attr('id');
        $('body').css('visibility', 'hidden');
        $("#" + modalId).css('visibility', 'visible');
        $('#' + modalId).removeClass('modal');
        window.print();
        $('body').css('visibility', 'visible');
        $('#' + modalId).addClass('modal');
    } else {
        window.print();
    }
});

here is the fiddle

many ways of getting this done, but finally it all depends on PHP version you are using. Here is summary of all solutions:

get PHP version:

echo phpinfo();

PHP 5.3+

$period = new DatePeriod(
     new DateTime('2010-10-01'),
     new DateInterval('P1D'),
     new DateTime('2010-10-05')
);

PHP 4+

/**
 * creating between two date
 * @param string since
 * @param string until
 * @param string step
 * @param string date format
 * @return array
 * @author Ali OYGUR <[email protected]>
 */
function dateRange($first, $last, $step = '+1 day', $format = 'd/m/Y' ) { 

    $dates = array();
    $current = strtotime($first);
    $last = strtotime($last);

    while( $current <= $last ) { 

        $dates[] = date($format, $current);
        $current = strtotime($step, $current);
    }

    return $dates;
}

PHP < 4

you should upgrade :)

NXJSON is full-featured yet very small (~400 lines of code) JSON parser, which has easy to use API:

const nx_json* json=nx_json_parse_utf8(code);
printf("hello=%s\n", nx_json_get(json, "hello")->text_value);
const nx_json* arr=nx_json_get(json, "my-array");
int i;
for (i=0; i<arr->length; i++) {
  const nx_json* item=nx_json_item(arr, i);
  printf("arr[%d]=(%d) %ld\n", i, (int)item->type, item->int_value);
}
nx_json_free(json);

Certainly a corner case for this error, but I received it in a different situation, when attempting to overload the assignment operator=. It was a bit cryptic IMO (from g++ 8.1.1).

#include <cstdint>

enum DataType
{
  DT_INT32,
  DT_FLOAT
};

struct PrimitiveData
{
  union MyData
  {
    int32_t i;
    float f;
  } data;

  enum DataType dt;

  template<typename T>
  void operator=(T data)
  {
    switch(dt)
    {
      case DT_INT32:
      {
        data.i = data;
        break;
      }
      case DT_FLOAT:
      {
        data.f = data;
        break;
      }
      default:
      {
        break;
      }
    }
  }
};

int main()
{
  struct PrimitiveData pd;
  pd.dt = DT_FLOAT;
  pd = 3.4f;

  return 0;
}

I received 2 "identical" errors

error: request for member ‘i’ [and 'f'] in ‘data’, which is of non-class type ‘float’

(The equivalent error for clang is: error: member reference base type 'float' is not a structure or union)

for the lines data.i = data; and data.f = data;. Turns out the compiler was confusing local variable name 'data' and my member variable data. When I changed this to void operator=(T newData) and data.i = newData;, data.f = newData;, the error went away.

If you:

• care about performance
• don't need the data in the file at execution time.
• want to go with conventional libraries vs rolling your own solution

pdf2htmlEX by coolwanglu is probably the best solution out there to convert a pdf file into html. You could do a simple convert and then embed the html page as an iframe or something similar.

An easy way to overcome this problem is to use 64 bit type

list = numpy.array(list, dtype=numpy.float64)

Your question is a bit unclear, but I think you want (requires using System.Linq;):

var result = yourArrayOfStrings.SelectMany(s => s).ToArray();

Another solution is:

var result = string.Concat(yourArrayOfStrings).ToCharArray();

Reference the checkbox by it's id and not with the # Assign the function to the onclick attribute rather than using the change attribute

var checkbox = $("save_" + fieldName);
checkbox.onclick = function(event) {
    var checkbox = event.target;

    if (checkbox.checked) {
        //Checkbox has been checked
    } else {
        //Checkbox has been unchecked
    }
};

What's the difference: See other answers.

When use + instead of %20? Use + if, for some reason, you want to make the URL query string (?.....) or hash fragment (#....) more readable. Example: You can actually read this:

https://www.google.se/#q=google+doesn%27t+encode+:+and+uses+%2B+instead+of+spaces (%2B = +)

But the following is a lot harder to read: (at least to me)

https://www.google.se/#q=google%20doesn%27t%20oops%20:%20%20this%20text%20%2B%20is%20different%20spaces

I would think + is unlikely to break anything, since Google uses + (see the 1st link above) and they've probably thought about this. I'm going to use + myself just because readable + Google thinks it's OK.

Initialize DataTable:

DataTable dt = new DataTable(); 
dt.Columns.Add("id", typeof(String)); 
dt.Columns.Add("name", typeof(String)); 
for (int i = 0; i < 5; i++)
{
    string index = i.ToString();
    dt.Rows.Add(new object[] { index, "name" + index });
}

Query itself:

IList<Class1> items = dt.AsEnumerable().Select(row => 
    new Class1
        {
            id = row.Field<string>("id"),
            name = row.Field<string>("name")
        }).ToList();

Another example:

new Promise(function(ok) {
   ok( 
      /* myFunc1(param1, param2, ..) */
   )
}).then(function(){
     /* myFunc1 succeed */
     /* Launch something else */
     /* console.log(whateverparam1) */
     /* myFunc2(whateverparam1, otherparam, ..) */
}).then(function(){
     /* myFunc2 succeed */
     /* Launch something else */
     /* myFunc3(whatever38, ..) */
})

The same logic using arrow functions shorthand.

?? This can cause issues with multiple calls see comments!

The syntax of the first snippet using plain function is preferable here.

new Promise((ok) =>
   ok( 
      /* myFunc1(param1, param2, ..) */
)).then(() =>
     /* myFunc1 succeed */
     /* Launch something else */
     /* Only ONE call or statment can be made inside arrow functions */
     /* For example, using console.log here will break everything */
     /* myFunc2(whateverparam1, otherparam, ..) */
).then(() =>
     /* myFunc2 succeed */
     /* Launch something else */
     /* Only ONE call or statment can be made inside arrow functions */
     /* For example, using console.log here will break everything */
     /* myFunc3(whatever38, ..) */
)

+1 for distinguishing between "empty" and NULL. I agree that "empty" should mean "valid, but blank" and "NULL" should mean "invalid."

So I'd answer your question like this:

empty when I want a valid default value that may or may not be changed, for example, a user's middle name.

NULL when it is an error if the ensuing code does not set the value explicitly.

This solution is for Vue-2 users:

1. In vue-2 if you don't like to keep your files in static folder (relevant info), or
2. In vue-2 & vue-cli-3 if you don't like to keep your files in public folder (static folder is renamed to public):

The simple solution is :)

<img src="@/assets/img/clear.gif" /> // just do this:
<img :src="require(`@/assets/img/clear.gif`)" // or do this:
<img :src="require(`@/assets/img/${imgURL}`)" // if pulling from: data() {return {imgURL: 'clear.gif'}}

If you like to keep your static images in static/assets/img or public/assets/img folder, then just do:

<img src="./assets/img/clear.gif" />
<img src="/assets/img/clear.gif" /> // in some case without dot ./

Also, for those who the solution above didn't work, here's is what worked for me:

I have a solution with multiple projects. All projects were in MVC3. I installed Visual Studio 2012 in my machine and it seems that some projects were automatically upgraded to MVC4.

I got this problem

The controller for path '/etc/etc' was not found or does not implement IController

because the project that handled that route was pointing to MVC4.

I had to manually update their references to use MVC3. You can also do that by opening the .csproj file with a text editor. Find the reference to MVC3 and remove this line:

<SpecificVersion>False</SpecificVersion>

You can do it in a single query:

Select t.Id, t.title, z.dupCount
From yourtable T
Join
   (select title, Count (*) dupCount
    from yourtable 
    group By title
    Having Count(*) > 1) z
   On z.title = t.Title
order By dupCount Desc

I don't know Sphinx, but as for Lucene vs a database full-text search, I think that Lucene performance is unmatched. You should be able to do almost any search in less than 10 ms, no matter how many records you have to search, provided that you have set up your Lucene index correctly.

Here comes the biggest hurdle though: personally, I think integrating Lucene in your project is not easy. Sure, it is not too hard to set it up so you can do some basic search, but if you want to get the most out of it, with optimal performance, then you definitely need a good book about Lucene.

As for CPU & RAM requirements, performing a search in Lucene doesn't task your CPU too much, though indexing your data is, although you don't do that too often (maybe once or twice a day), so that isn't much of a hurdle.

It doesn't answer all of your questions but in short, if you have a lot of data to search, and you want great performance, then I think Lucene is definitely the way to go. If you're not going to have that much data to search, then you might as well go for a database full-text search. Setting up a MySQL full-text search is definitely easier in my book.

    <RadioGroup
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/txtLastNameSignUp"
        android:layout_margin="20dp"
        android:orientation="horizontal"
        android:id="@+id/radioGroup">
<RadioButton
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:checked="true"
    android:id="@+id/Male"
    android:text="Male"/>
        <RadioButton
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/Female"
            android:text="Female"/>
        </RadioGroup>

This type of the function belongs to element operators. Some useful element operators are defined below.

1. First/FirstOrDefault
2. Last/LastOrDefault
3. Single/SingleOrDefault

We use element operators when we need to select a single element from a sequence based on a certain condition. Here is an example.

  List<int> items = new List<int>() { 8, 5, 2, 4, 2, 6, 9, 2, 10 };

First() operator returns the first element of a sequence after satisfied the condition. If no element is found then it will throw an exception.

int result = items.Where(item => item == 2).First();

FirstOrDefault() operator returns the first element of a sequence after satisfied the condition. If no element is found then it will return default value of that type.

int result1 = items.Where(item => item == 2).FirstOrDefault();

1) Just remove \bin from Java_home environmental Variable. This worked for me .
2) Also make sure you are using the correct versions of android studio and Java (32/64 bit)

Instead of

from keras.datasets import imdb

use

from tensorflow.keras.datasets import imdb

top_words = 10000
((x_train, y_train), (x_test, y_test)) = imdb.load_data(num_words=top_words, seed=21)

You could use Kernel#test:

test ?d, 'some directory'

it gets it's origins from https://ss64.com/bash/test.html you will notice bash test has this flag -d to test if a directory exists -d file True if file is a Directory. [[ -d demofile ]]

Sure you can. Something like:

HTML

<div ng-controller="fessCntrl">    
     <label ng-repeat="(key,val) in list">
       <input type="radio" name="localityTypeRadio" ng-model="$parent.localityTypeRadio" ng-value="key" />{{key}}
         <div ng-if="key == 'City' || key == 'County'">
             <pre>City or County !!! {{$parent.localityTypeRadio}}</pre>
         </div>
         <div ng-if="key == 'Town'">
             <pre>Town!!! {{$parent.localityTypeRadio}}</pre>
         </div>        
      </label>
</div>

JS

var fessmodule = angular.module('myModule', []);

fessmodule.controller('fessCntrl', function ($scope) {

    $scope.list = {
        City: [{name: "cityA"}, {name: "cityB"}],
        County: [{ name: "countyA"}, {name: "countyB"}],
        Town: [{ name: "townA"}, {name: "townB"}]
      };

    $scope.localityTypeRadio = 'City';
});

fessmodule.$inject = ['$scope'];

Demo Fiddle

Optional parameters are kind of like a macro substitution from what I understand. They are not really optional from the method's point of view. An artifact of that is the behavior you see where you get different results if you cast to an interface.

$(document).ready(my_function);

Or

$(document).ready(function () {
  // Function code here.
});

Or the shorter but less readable variant:

$(my_function);

All of these will cause my_function to be called after the DOM loads.

See the ready event documentation for more details.

Binds a function to be executed whenever the DOM is ready to be traversed and manipulated.

Edit:

To simulate a click, use the click() method without arguments:

$('#button').click();

From the docs:

Triggers the click event of each matched element. Causes all of the functions that have been bound to that click event to be executed.

To put it all together, the following code simulates a click when the document finishes loading:

$(function () {
  $('#button').click();
});

Sorted set:

return new TreeSet(setIWantSorted);

or:

return new ArrayList(new TreeSet(setIWantSorted));

Notepad++ Add Word To Start Of Every Line

You can use this npm module: https://github.com/sparkalow/angular-truncate

Inject the truncate filter into your app module like this:

var myApp = angular.module('myApp', ['truncate']); 

and apply the filter in your app this way:

{{ text | characters:20 }} 

AFAIK $(window).height(); returns the height of your window and $(document).height(); returns the height of your document

mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).

I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.

Try this,

// prepare json data
let json: [String: Any] = ["title": "ABC",
                           "dict": ["1":"First", "2":"Second"]]

let jsonData = try? JSONSerialization.data(withJSONObject: json)

// create post request
let url = URL(string: "http://httpbin.org/post")!
var request = URLRequest(url: url)
request.httpMethod = "POST"

// insert json data to the request
request.httpBody = jsonData

let task = URLSession.shared.dataTask(with: request) { data, response, error in
    guard let data = data, error == nil else {
        print(error?.localizedDescription ?? "No data")
        return
    }
    let responseJSON = try? JSONSerialization.jsonObject(with: data, options: [])
    if let responseJSON = responseJSON as? [String: Any] {
        print(responseJSON)
    }
}

task.resume()

To add to marcio's awesome solution, dismissActionSheet: can be implemented as follows.

1. Add an ActionSheet object to your .h file, synthesize it and reference it in your .m file.

2. Add this method to your code.

   - (void)dismissActionSheet:(id)sender{
     [_actionSheet dismissWithClickedButtonIndex:0 animated:YES];
     [_myButton setTitle:@"new title"]; //set to selected text if wanted
   }
   

you can also use $sce.trustAsHtml('"<h1>" + str + "</h1>"'),if you want to know more detail, please refer to $sce

CHARINDEX() searches for a substring within a larger string, and returns the position of the match, or 0 if no match is found

if CHARINDEX('ME',@mainString) > 0
begin
    --do something
end

Edit or from daniels answer, if you're wanting to find a word (and not subcomponents of words), your CHARINDEX call would look like:

CHARINDEX(' ME ',' ' + REPLACE(REPLACE(@mainString,',',' '),'.',' ') + ' ')

(Add more recursive REPLACE() calls for any other punctuation that may occur)

You can also download swagger ui from: https://github.com/swagger-api/swagger-ui, take the dist folder, modify index.html: change the constructor

const ui = SwaggerUIBundle({
    url: ...,

into

const ui = SwaggerUIBundle({
    spec: YOUR_JSON,

now the dist folder contains all what you need and can be distributed as is

How I would do this

git checkout master
git pull origin master
git merge test
git push origin master

If I have a local branch from a remote one, I don't feel comfortable with merging other branches than this one with the remote. Also I would not push my changes, until I'm happy with what I want to push and also I wouldn't push things at all, that are only for me and my local repository. In your description it seems, that test is only for you? So no reason to publish it.

git always tries to respect yours and others changes, and so will --rebase. I don't think I can explain it appropriately, so have a look at the Git book - Rebasing or git-ready: Intro into rebasing for a little description. It's a quite cool feature

Or, if you are a fan of functional programming:

>>> a = [133, 53, 234, 241]
>>> "".join(map(lambda b: format(b, "02x"), a))
8535eaf1
>>>

Procedural languages tend to keep track of state (using variables) and tend to execute as a sequence of steps. Purely functional languages don't keep track of state, use immutable values, and tend to execute as a series of dependencies. In many cases the status of the call stack will hold the information that would be equivalent to that which would be stored in state variables in procedural code.

Recursion is a classic example of functional style programming.

Not sure if JSF provides a built-in functionality, but you could use java.sql.Date's constructor to convert to a date object: http://download.oracle.com/javase/1.5.0/docs/api/java/sql/Date.html#Date(long)

Then you should be able to use higher level features provided by Java SE, Java EE to display and format the extracted date. You could instantiate a java.util.Calendar and explicitly set the time: http://download.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#setTime(java.util.Date)

EDIT: The JSF components should not take care of the conversion. Your data access layer (persistence layer) should take care of this. In other words, your JSF components should not handle the long typed attributes but only a Date or Calendar typed attributes.

Floating point numbers in C use IEEE 754 encoding.

This type of encoding uses a sign, a significand, and an exponent.

Because of this encoding, many numbers will have small changes to allow them to be stored.

Also, the number of significant digits can change slightly since it is a binary representation, not a decimal one.

Single precision (float) gives you 23 bits of significand, 8 bits of exponent, and 1 sign bit.

Double precision (double) gives you 52 bits of significand, 11 bits of exponent, and 1 sign bit.

How about using the wsdl /server or wsdl /serverinterface switches? As far as I understand the wsdl.exe command line properties, that's what you're looking for.

- ADVANCED -

/server

Server switch has been deprecated. Please use /serverInterface instead.
Generate an abstract class for an xml web service implementation using
ASP.NET based on the contracts. The default is to generate client proxy
classes.

On the other hand: why do you want to create obsolete technology solutions? Why not create this web service as a WCF service. That's the current and more modern, much more flexible way to do this!

Marc

UPDATE:

When I use wsdl /server on a WSDL file, I get this file created:

[WebService(Namespace="http://.......")]
public abstract partial class OneCrmServiceType : System.Web.Services.WebService 
{
    /// <remarks/>
    [WebMethod]
    public abstract void OrderCreated(......);
}

This is basically almost exactly the same code that gets generated when you add an ASMX file to your solution (in the code behind file - "yourservice.asmx.cs"). I don't think you can get any closer to creating an ASMX file from a WSDL file.

You can always add the "yourservice.asmx" manually - it doesn't really contain much:

<%@ WebService Language="C#" CodeBehind="YourService.asmx.cs" 
      Class="YourServiceNamespace.YourServiceClass" %>

If you have date as a datetime.datetime (or a datetime.date) instance and want to combine it via a time from a datetime.time instance, then you can use the classmethod datetime.datetime.combine:

import datetime
dt = datetime.datetime(2020, 7, 1)
t = datetime.time(12, 34)
combined = datetime.datetime.combine(dt.date(), t)

Your response must return some sort of Response object. You can't just return an object.

So change it to something like:

return Response::json($promotion);

or my favorite using the helper function:

return response()->json($promotion);

If returning a response doesn't work it may be some sort of encoding issue. See this article: The Response content must be a string or object implementing __toString(), \"boolean\" given."

Array.prototype.map() index:

One can access the index Array.prototype.map() via the second argument of the callback function. Here is an example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
_x000D_
const map = array.map((x, index) => {_x000D_
  console.log(index);_x000D_
  return x + index;_x000D_
});_x000D_
_x000D_
console.log(map);

Other arguments of Array.prototype.map():

• The third argument of the callback function exposes the array on which map was called upon
• The second argument of Array.map() is a object which will be the this value for the callback function. Keep in mind that you have to use the regular function keyword in order to declare the callback since an arrow function doesn't have its own binding to the this keyword.

For example:

const array = [1, 2, 3, 4];_x000D_
_x000D_
const thisObj = {prop1: 1}_x000D_
_x000D_
_x000D_
const map = array.map( function (x, index, array) {_x000D_
  console.log(array);_x000D_
  console.log(this)_x000D_
}, thisObj);

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

SELECT ID
  FROM A
 WHERE ID NOT IN (
      SELECT ID
        FROM B);

SELECT ID    
  FROM A a
 WHERE NOT EXISTS (
      SELECT 1 
        FROM B b
       WHERE b.ID = a.ID)

         SELECT a.ID 
           FROM A a    
LEFT OUTER JOIN B b 
             ON a.ID = b.ID    
          WHERE b.ID IS NULL

DELETE 
  FROM A 
 WHERE ID NOT IN (
      SELECT ID 
        FROM B) 

You can use css

.ads{pointer-events:none}

or Using javascript prevent event

$("selector").click(function(event){
   event.preventDefault();
});

Mongodb was not running but I had the module for node.js The database path was missing. Fix was create new folder in the root so run sudo mkdir -p /data/db/ then run sudo chown id -u /data/db

Modern string formatting:

"{} and {}".format("string", 1)

You can use: marshaller.setProperty("jaxb.fragment", Boolean.TRUE);

It works for me on Java 8

I encountered this problem in Laravel 5.8, what I did was to do composer require for each library and all where installed correctly.

Like so:

instead of adding it to the composer.json file or specifying a version:

composer require msurguy/honeypot: dev-master

I instead did without specifying any version:

composer require msurguy/honeypot

I hope it helps, thanks

You can see here http://msdn.microsoft.com/en-us/library/system.iformatprovider.aspx

See the remarks and example section there.

This works in Bash without forking external commands:

function has_substring() {
   [[ "$1" != "${2/$1/}" ]]
}

Example usage:

name="hello/world"
if has_substring "$name" "/"
then
   echo "Indeed, $name contains a slash!"
fi

You can attach a SLOT to the

void aboutToQuit();

signal of your QApplication. This signal should be raised just before app closes.

Use above annotation if someone is facing :--org.hibernate.jpa.HibernatePersistenceProvider persistence provider when it attempted to create the container entity manager factory for the paymentenginePU persistence unit. The following error occurred: [PersistenceUnit: paymentenginePU] Unable to build Hibernate SessionFactory ** This is a solution if you are using Audit table.@Audit

Use:- @Audited(targetAuditMode = RelationTargetAuditMode.NOT_AUDITED) on superclass.

Your requirements are all over the place, but this is the solution to my understanding of them:

To group by Reference property:

var refGroupQuery = (from m in context.Measurements
            group m by m.Reference into refGroup
            select refGroup);

Now you say you want to limit results by "most recent numOfEntries" - I take this to mean you want to limit the returned Measurements... in that case:

var limitedQuery = from g in refGroupQuery
                   select new
                   {
                       Reference = g.Key,
                       RecentMeasurements = g.OrderByDescending( p => p.CreationTime ).Take( numOfEntries )
                   }

To order groups by first Measurement creation time (note you should order the measurements; if you want the earliest CreationTime value, substitue "g.SomeProperty" with "g.CreationTime"):

var refGroupsOrderedByFirstCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.OrderBy( g => g.SomeProperty ).First().CreationTime );

To order groups by average CreationTime, use the Ticks property of the DateTime struct:

var refGroupsOrderedByAvgCreationTimeQuery = limitedQuery.OrderBy( lq => lq.RecentMeasurements.Average( g => g.CreationTime.Ticks ) );

pkill -9 python

should kill any running python process.

Following on from the examples already given, I'd say, it's best practice to also wrap the response in a using like this

    public bool IsValidUrl(string url)
    {
         try
         {
             var request = WebRequest.Create(url);
             request.Timeout = 5000;
             request.Method = "HEAD";

             using (var response = (HttpWebResponse)request.GetResponse())
             {
                response.Close();
                return response.StatusCode == HttpStatusCode.OK;
            }
        }
        catch (Exception exception)
        { 
            return false;
        }
   }

I like the solution provided by 360Airwalk, but it may be improved a bit.

The first problem is that if you make $.post() with empty data, jQuery doesn't add a Content-Type header, and in this case ASP.NET MVC fails to receive and check the token. So you have to ensure the header is always there.

Another improvement is support of all HTTP verbs with content: POST, PUT, DELETE etc. Though you may use only POSTs in your application, it's better to have a generic solution and verify that all data you receive with any verb has an anti-forgery token.

$(document).ready(function () {
    var securityToken = $('[name=__RequestVerificationToken]').val();
    $(document).ajaxSend(function (event, request, opt) {
        if (opt.hasContent && securityToken) {   // handle all verbs with content
            var tokenParam = "__RequestVerificationToken=" + encodeURIComponent(securityToken);
            opt.data = opt.data ? [opt.data, tokenParam].join("&") : tokenParam;
            // ensure Content-Type header is present!
            if (opt.contentType !== false || event.contentType) {
                request.setRequestHeader( "Content-Type", opt.contentType);
            }
        }
    });
});

If you need wait until the ajax call is completed all do you need is make your call synchronously.

Here's the way I use for counting the number of physical cores that are online on Linux:

lscpu --online --parse=Core,Socket | grep --invert-match '^#' | sort --unique | wc --lines

or in short:

lscpu -b -p=Core,Socket | grep -v '^#' | sort -u | wc -l

Example (1 socket):

> lscpu
...
CPU(s):                28
Thread(s) per core:    2
Core(s) per socket:    14
Socket(s):             1
....
> lscpu -b -p=Core,Socket | grep -v '^#' | sort -u | wc -l
14

Example (2 sockets):

> lscpu
...
CPU(s):                56
Thread(s) per core:    2
Core(s) per socket:    14
Socket(s):             2
...
> lscpu -b -p=Core,Socket | grep -v '^#' | sort -u | wc -l
28

Example (4 sockets):

> lscpu
...
CPU(s):                64
Thread(s) per core:    2
Core(s) per socket:    8
Socket(s):             4
...
> lscpu -b -p=Core,Socket | grep -v '^#' | sort -u | wc -l

There are several ways I can think of to do this.

Use a callback:

 function FunctInit(someVarible){
      //init and fill screen
      AndroidCallGetResult();  // Enables Android button.
 }

 function getResult(){ // Called from Android button only after button is enabled
      //return some variables
 }

Use a Timeout (this would probably be my preference):

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      if (inited) {
           //return some variables
      } else {
           setTimeout(getResult, 250);
      }
 }

Wait for the initialization to occur:

 var inited = false;
 function FunctInit(someVarible){
      //init and fill screen
      inited = true;
 }

 function getResult(){
      var a = 1;
      do { a=1; }
      while(!inited);
      //return some variables
 }

I think that in this question is missing one important information.

How many records will you insert?

1. If from 1 to cca. 10.000 then you should use SQL statement (Like they said it is easy to understand and it is easy to write).
2. If from cca. 10.000 to cca. 100.000 then you should use cursor, but you should add logic to commit on every 10.000 records.
3. If from cca. 100.000 to millions then you should use bulk collect for better performance.

html is not a view engine , but ejs offers the possibility to write html code within it

You don't need a regex for this one. Use the isNAN() JavaScript function.

The isNaN() function determines whether a value is an illegal number (Not-a-Number). This function returns true if the value is NaN, and false if not.

if (isNaN($('#Field').val()) == false) {

    // It's a number
}

I recently ran into a problem of same kind and found said solution which turned out to be only satisfying if you have numbers that go within a certain formation. For example if you want to one-hot encode following list:

all_good_list = [0,1,2,3,4]

go ahead, the posted solutions are already mentioned above. But what if considering this data:

problematic_list = [0,23,12,89,10]

If you do it with methods mentioned above, you will likely end up with 90 one-hot columns. This is because all answers include something like n = np.max(a)+1. I found a more generic solution that worked out for me and wanted to share with you:

import numpy as np
import sklearn
sklb = sklearn.preprocessing.LabelBinarizer()
a = np.asarray([1,2,44,3,2])
n = np.unique(a)
sklb.fit(n)
b = sklb.transform(a)

I hope someone encountered same restrictions on above solutions and this might come in handy

POSIX 7

First find the function: http://pubs.opengroup.org/onlinepubs/9699919799/functions/nanosleep.html

That contains a link to a time.h, which as a header should be where structs are defined:

The header shall declare the timespec structure, which shall > include at least the following members:

time_t  tv_sec    Seconds. 
long    tv_nsec   Nanoseconds.

man 2 nanosleep

Pseudo-official glibc docs which you should always check for syscalls:

struct timespec {
    time_t tv_sec;        /* seconds */
    long   tv_nsec;       /* nanoseconds */
};

Promise.allSettled

Instead of Promise.all use Promise.allSettled which waits for all promises to settle, regardless of the result

let p1 = new Promise(resolve => resolve("result1"));
let p2 = new Promise( (resolve,reject) => reject('some troubles') );
let p3 = new Promise(resolve => resolve("result3"));

// It returns info about each promise status and value
Promise.allSettled([p1,p2,p3]).then(result=> console.log(result));

Polyfill

if (!Promise.allSettled) {
  const rejectHandler = reason => ({ status: 'rejected', reason });
  const resolveHandler = value => ({ status: 'fulfilled', value });

  Promise.allSettled = function (promises) {
    const convertedPromises = promises
      .map(p => Promise.resolve(p).then(resolveHandler, rejectHandler));
    return Promise.all(convertedPromises);
  };
}

Another way to look at it is to consider git rebase master as:

Rebase the current branch on top of master

Here , 'master' is the upstream branch, and that explain why, during a rebase, ours and theirs are reversed.

I really don't like the fact that, because of the "promise" way of doing things, the consumer of the service that uses $http has to "know" about how to unpack the response.

I just want to call something and get the data out, similar to the old $scope.items = Data.getData(); way, which is now deprecated.

I tried for a while and didn't come up with a perfect solution, but here's my best shot (Plunker). It may be useful to someone.

app.factory('myService', function($http) {
  var _data;  // cache data rather than promise
  var myService = {};

  myService.getData = function(obj) { 
    if(!_data) {
      $http.get('test.json').then(function(result){
        _data = result.data;
        console.log(_data);  // prove that it executes once
        angular.extend(obj, _data);
      }); 
    } else {  
      angular.extend(obj, _data);
    }
  };

  return myService;
}); 

Then controller:

app.controller('MainCtrl', function( myService,$scope) {
  $scope.clearData = function() {
    $scope.data = Object.create(null);
  };
  $scope.getData = function() {
    $scope.clearData();  // also important: need to prepare input to getData as an object
    myService.getData($scope.data); // **important bit** pass in object you want to augment
  };
});

Flaws I can already spot are

• You have to pass in the object which you want the data added to, which isn't an intuitive or common pattern in Angular
• getData can only accept the obj parameter in the form of an object (although it could also accept an array), which won't be a problem for many applications, but it's a sore limitation
• You have to prepare the input object $scope.data with = {} to make it an object (essentially what $scope.clearData() does above), or = [] for an array, or it won't work (we're already having to assume something about what data is coming). I tried to do this preparation step IN getData, but no luck.

Nevertheless, it provides a pattern which removes controller "promise unwrap" boilerplate, and might be useful in cases when you want to use certain data obtained from $http in more than one place while keeping it DRY.

You can stop a macro by pressing ctrl + break but if you don't have the break key you could use this autohotkey (open source) code:

+ESC:: SendInput {CtrlBreak} return

Pressing shift + Escape will be like pressing ctrl + break and thus will stop your macro.

I always had problems with that, and I made a getx.bat script:

:: with \m read system environment

@SETLOCAL EnableDelayedExpansion

I had a similar issue, so here are few things that I did try (not in any order, except for the solution :) )

1. Changed the foreign key names (it didn't work)
2. Reduced the foreign key length
3. Verified the datatypes (darn nothing wrong)
4. Check indexes
5. Check the collations (everything fine, darn again)
6. Truncated the table, of no good use
7. Dropped the table and re-created
8. Tried to see if any circular reference is being created --- all fine

9. Finally, I saw that I had two editors open. One that in PhpStorm (JetBrains) and the other MySQL workbench. It seems that the PhpStorm / MySQL Workbench creates some kind of edit lock.

   I closed PhpStorm just to check if locking was the case (it could have been the other way around). This solved my problem.

JQuery example provided in this thread was extremely outdated, and google wasn't helpful at all so here is my revision:

 <script type="text/javascript">
        $('#image-file').on('change', function() {
            console.log($(this)[0].files[0].name+' file size is: ' + $(this)[0].files[0].size/1024/1024 + 'Mb');
        });
    </script>

strtotime() gives you a number back that represents a time in seconds. To increment it, add the corresponding number of seconds you want to add. 10 hours = 60*60*10 = 36000, so...

$date = date('h:i:s A', strtotime($today)+36000); // $today is today date

Edit: I had assumed you had a string time in $today - if you're just using the current time, even simpler:

$date = date('h:i:s A', time()+36000); // time() returns a time in seconds already

i had the same issues a longtime then i got the solution by the below code. please use

parent.jQuery.fancybox.close()

Although I like fhucho's recommendation of

String.valueOf(i)

The irony is that this method actually calls

Integer.toString(i)

Thus, use String.valueOf(i) if you like how it reads and you don't need radix, but also knowing that it is less efficient than Integer.toString(i).

One item that seems to have been missed is star transformations. Index Intersection operators resolve the predicate by calculating the set of rows hit by each of the predicates before any I/O is done on the fact table. On a star schema you would index each individual dimension key and the query optimiser can resolve which rows to select by the index intersection computation. The indexes on individual columns give the best flexibility for this.

Doing the following steps helped in my case:

1) open Settings 2) go to Git and Uncheck "Use credential helper" checkbox 3) Do git pull 4) Enter password in the pop up dialog

Git operations will now work fine in IntelliJ!

You are not seeding the number.

Use This:

#include <iostream>
#include <ctime>

using namespace std;

int main()
{
    srand(static_cast<unsigned int>(time(0)));
    cout << (rand() % 100) << endl;
    return 0;
}

You only need to seed it once though. Basically don't seed it every random number.

1. You can iterate using the index access,

2. To avoid O(n^2) complexity you can use two indices, i - current testing index, j - index to store next item and at the end of the cycle new size of the vector.

code:

void erase(std::vector<int>& v, int num)
{
  size_t j = 0;
  for (size_t i = 0; i < v.size(); ++i) {
    if (v[i] != num) v[j++] = v[i];
  }
  // trim vector to new size
  v.resize(j);
}

In such case you have no invalidating of iterators, complexity is O(n), and code is very concise and you don't need to write some helper classes, although in some case using helper classes can benefit in more flexible code.

This code does not use erase method, but solves your task.

Using pure stl you can do this in the following way (this is similar to the Motti's answer):

#include <algorithm>

void erase(std::vector<int>& v, int num) {
    vector<int>::iterator it = remove(v.begin(), v.end(), num);
    v.erase(it, v.end());
}

Make your size a factor in your dataframe by:

temp$size_f = factor(temp$size, levels=c('50%','100%','150%','200%'))

Then change the facet_grid(.~size) to facet_grid(.~size_f)

Then plot:

The graphs are now in the correct order.

This should do it:

SELECT report_id, computer_id, date_entered
FROM reports AS a
WHERE date_entered = (
    SELECT MAX(date_entered)
    FROM reports AS b
    WHERE a.report_id = b.report_id
      AND a.computer_id = b.computer_id
)

Assuming it's a server control, you can use Request["ButtonName"]

To see if a specific button was clicked: if (Request["ButtonName"] != null)

In my case the trouble was I didn't put the components that contain the datasource in the declarations of main module.

NgModule({
  imports: [
    EnterpriseConfigurationsRoutingModule,
    SharedModule
  ],
  declarations: [
    LegalCompanyTypeAssignComponent,
    LegalCompanyTypeAssignItemComponent,
    ProductsOfferedListComponent,
    ProductsOfferedItemComponent,
    CustomerCashWithdrawalRangeListComponent,
    CustomerCashWithdrawalRangeItemComponent,
    CustomerInitialAmountRangeListComponent,
    CustomerInitialAmountRangeItemComponent,
    CustomerAgeRangeListComponent,
    CustomerAgeRangeItemComponent,
    CustomerAccountCreditRangeListComponent, //<--This component contains the dataSource
    CustomerAccountCreditRangeItemComponent,
  

  ],

The component contains the dataSource:

export class CustomerAccountCreditRangeListComponent implements OnInit {

  @ViewChild(MatPaginator) set paginator(paginator: MatPaginator){
    this.dataSource.paginator = paginator;
  }
  @ViewChild(MatSort) set sort(sort: MatSort){
    this.dataSource.sort = sort;
  }

  dataSource = new MatTableDataSource(); //<--The dataSource used in HTML
  loading: any;
  resultsLength: any;
  displayedColumns: string[] = ["id", "desde", "hasta", "tipoClienteNombre", "eliminar"];
  data: any;

  constructor(
    private crud: CustomerAccountCreditRangeService,
    public snackBar: MatSnackBar,
    public dialog: MatDialog,
    private ui: UIComponentsService
  ) {
  }

This is for Angular 9

append 0 before it by checking if the value falls between 1 and 9 by first casting it to varchar

select case when DATEPART(month, getdate()) between 1 and 9 
then '0' else '' end + cast(DATEPART(month, getdate()) as varchar(2))

HTML controls the semantic meaning of the elements. CSS controls the layout/style of the page. Use CSS when you are controlling your layout.

In short, never use size=""

make your class public access modifier,

just add public keyword infront of your class name

Just wanted to add that GIF "transparency" is more like missing pixels. If you use GIF then you will see jagged edges where the background and the rest of the image meet. Using PNG, you can smoothly "composite" images together, which is what you really want. Plus PNG supports highly quality images.

Don't use "Paint". There are many high quality art applications for doing art work. I think even the cell phone apps (Pixlr is pretty good and free!) and web-based image editting apps are better. I use Gimp - free for all platforms.

While a JPEG can't be made transparent in and of itself, if your goal is to reduce the size of very large image areas for the web that need to contain transparent image areas, then there is a solution. It's a bit too complicated to post details, but Google it. Basically, you create your image with transparency and then split out the alpha channel (Gimp can do this easily) as a simple 8-bit greyscale PNG. Then you export the color data as a JPG. Now your web page uses a CANVAS tag to load the JPG as image data and applies the 8-bit greyscale PNG as the Canvas's alpha channel. The browser's Canvas does the work of making the image transparent. The JPEG stores the color info (better compressed than PNG) and the PNG is reduced to 8-bit alpha so its considerably smaller. I've saved a few hundred K per image using this technique. A few people have proposed file formats that embed PNG transparency info into a JPEG's extended information fields, but these proposal's don't have wide support as of yet.

For who are in rush for test execution, I had to use VS 2017 test explorer to run tests;

Try this:

$("input[type=checkbox]").prop('checked', true).uniform();

This code is very simple:

<select class="form-control" id="marasemaat" style="margin-top: 10%;font-size: 13px;" [(ngModel)]="fullNamePresentor" [formControl]="stateControl"  
            (change)="onSelect($event.target.value)">
            <option *ngFor="let char of programInfo1;let i = index;"   onclick="currentSlide(9,false)" value={{char.id}}>{{char.title + " "}}  ----> {{char.name + " "+ char.family }} ---- > {{(char.time.split('T', 2)[1]).split(':',2)}}</option>
  
          </select>

Like the others said:

inputString.split('\n')  # --> ['Line 1', 'Line 2', 'Line 3']

This is identical to the above, but the string module's functions are deprecated and should be avoided:

import string
string.split(inputString, '\n')  # --> ['Line 1', 'Line 2', 'Line 3']

Alternatively, if you want each line to include the break sequence (CR,LF,CRLF), use the splitlines method with a True argument:

inputString.splitlines(True)  # --> ['Line 1\n', 'Line 2\n', 'Line 3']

In addition to previous post you can have

<h:form rendered="#{!bean.boolvalue}" />
<h:form rendered="#{bean.textvalue == 'value'}" />

Its very simple, just add the quartzCore header in your file(for that you have to add the quartz framework to your project)

and then do this

[[button layer] setCornerRadius:8.0f];

[[button layer] setMasksToBounds:YES];

[[button layer] setBorderWidth:1.0f];

you can change the float values as required.

enjoy.

Here's some typical modern code ...

self.buttonTag.layer.borderWidth = 1.0f;
self.buttonCancel.layer.borderWidth = 1.0f;

self.buttonTag.layer.borderColor = [UIColor blueColor].CGColor;
self.buttonCancel.layer.borderColor = [UIColor blueColor].CGColor;

self.buttonTag.layer.cornerRadius = 4.0f;
self.buttonCancel.layer.cornerRadius = 4.0f;

that's a similar look to segmented controls.

UPDATE for Swift:

• No need to add "QuartzCore"

Just do:

button.layer.cornerRadius = 8.0
button.layer.borderWidth = 1.0
button.layer.borderColor = UIColor.black.cgColor

Maybe you can use float:right;:

.one {_x000D_
  padding-left: 1em;_x000D_
  text-color: white;_x000D_
   display:inline; _x000D_
}_x000D_
.two {_x000D_
  background-color: #00ffff;_x000D_
}_x000D_
.pull-right{_x000D_
  float:right;_x000D_
}

Just put your mouse on the line to copy and do CTRL+C ,afterwards CTRL+V on the same line. Works like magic :-)

You can get a View's coordinates using getLocationOnScreen() or getLocationInWindow()

Afterwards, x and y should be the top-left corner of the view. If your root layout is smaller than the screen (like in a Dialog), using getLocationInWindow will be relative to its container, not the entire screen.

Java Solution

int[] point = new int[2];
view.getLocationOnScreen(point); // or getLocationInWindow(point)
int x = point[0];
int y = point[1];

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post(() -> {
    // Values should no longer be 0
    int[] point = new int[2];
    view.getLocationOnScreen(point); // or getLocationInWindow(point)
    int x = point[0];
    int y = point[1];
});

~~

Kotlin Solution

val point = IntArray(2)
view.getLocationOnScreen(point) // or getLocationInWindow(point)
val (x, y) = point

NOTE: If value is always 0, you are likely changing the view immediately before requesting location.

To ensure view has had a chance to update, run your location request after the View's new layout has been calculated by using view.post:

view.post {
    // Values should no longer be 0
    val point = IntArray(2)
    view.getLocationOnScreen(point) // or getLocationInWindow(point)
    val (x, y) = point
}

I recommend creating an extension function for handling this:

// To use, call:
val (x, y) = view.screenLocation

val View.screenLocation get(): IntArray {
    val point = IntArray(2)
    getLocationOnScreen(point)
    return point
}

And if you require reliability, also add:

view.screenLocationSafe { x, y -> Log.d("", "Use $x and $y here") }

fun View.screenLocationSafe(callback: (Int, Int) -> Unit) {
    post {
        val (x, y) = screenLocation
        callback(x, y)
    }
}

HttpContext.Current returns an instance of System.Web.HttpContext, which does not extend System.Web.HttpContextBase. HttpContextBase was added later to address HttpContext being difficult to mock. The two classes are basically unrelated (HttpContextWrapper is used as an adapter between them).

Fortunately, HttpContext itself is fakeable just enough for you do replace the IPrincipal (User) and IIdentity.

The following code runs as expected, even in a console application:

HttpContext.Current = new HttpContext(
    new HttpRequest("", "http://tempuri.org", ""),
    new HttpResponse(new StringWriter())
    );

// User is logged in
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity("username"),
    new string[0]
    );

// User is logged out
HttpContext.Current.User = new GenericPrincipal(
    new GenericIdentity(String.Empty),
    new string[0]
    );

Addition to above all simplified responses.

If you are working with files in bash script, it's better to use file descriptor.

For example: If you want to read and write from/to the file "test.txt", use the file descriptor as show below:

FILE=$1 # give the name of file in the command line
exec 5<>$FILE # '5' here act as the file descriptor

# Reading from the file line by line using file descriptor
while read LINE; do
    echo "$LINE"
done <&5

# Writing to the file using descriptor
echo "Adding the date: `date`" >&5 
exec 5<&- # Closing a file descriptor

Here's an example, because an example is often clearer than a long explanation. Suppose foo is a variable of type long. The following operation is not an atomic operation:

foo = 65465498L;

Indeed, the variable is written using two separate operations: one that writes the first 32 bits, and a second one which writes the last 32 bits. That means that another thread might read the value of foo, and see the intermediate state.

Making the operation atomic consists in using synchronization mechanisms in order to make sure that the operation is seen, from any other thread, as a single, atomic (i.e. not splittable in parts), operation. That means that any other thread, once the operation is made atomic, will either see the value of foo before the assignment, or after the assignment. But never the intermediate value.

A simple way of doing this is to make the variable volatile:

private volatile long foo;

Or to synchronize every access to the variable:

public synchronized void setFoo(long value) {
    this.foo = value;
}

public synchronized long getFoo() {
    return this.foo;
}
// no other use of foo outside of these two methods, unless also synchronized

Or to replace it with an AtomicLong:

private AtomicLong foo;

I've faced two different scenarios here:

1) When I want the asynchronous task to finish anyway: imagine my onPostExecute does store data received and then call a listener to update views so, to be more efficient, I want the task to finish anyway so I have the data ready when user cames back. In this case I usually do this:

@Override
protected void onPostExecute(void result) {
    // do whatever you do to save data
    if (this.getView() != null) {
        // update views
    }
}

2) When I want the asynchronous task only to finish when views can be updated: the case you're proposing here, the task only updates the views, no data storage needed, so it has no clue for the task to finish if views are not longer being showed. I do this:

@Override
protected void onStop() {
    // notice here that I keep a reference to the task being executed as a class member:
    if (this.myTask != null && this.myTask.getStatus() == Status.RUNNING) this.myTask.cancel(true);
    super.onStop();
}

I've found no problem with this, although I also use a (maybe) more complex way that includes launching tasks from the activity instead of the fragments.

Wish this helps someone! :)

Click on the drop down next to the Run button, After that choose Run Configuration, shows three option, for example i choose java application add class(Name of the class of your project) in that then Click on the ok button ...Run your application :)

I used @qwertyjones's answer to automate logging into Oracle Agile with a public password.

I saved the login page as index.html, edited all the href= and action= fields to have the full URL to the Agile server.

The key <form> line needed to change from

<form autocomplete="off" name="MainForm" method="POST"
 action="j_security_check" 
 onsubmit="return false;" target="_top">

to

<form autocomplete="off" name="MainForm" method="POST"
 action="http://my.company.com:7001/Agile/default/j_security_check"   
 onsubmit="return false;" target="_top">

I also added this snippet to the end of the <body>

<script>
function checkCookiesEnabled(){ return true; }
document.MainForm.j_username.value = "joeuser";
document.MainForm.j_password.value = "abcdef";
submitLoginForm();
</script> 

I had to disable the cookie check by redefining the function that did the check, because I was hosting this from XAMPP and I didn't want to deal with it. The submitLoginForm() call was inspired by inspecting the keyPressEvent() function.

numpy.where() is my favorite.

>>> x = numpy.array([1,0,2,0,3,0,4,5,6,7,8])
>>> numpy.where(x == 0)[0]
array([1, 3, 5])

Whenever you wish to exit all open activities, you should press a button which loads the first Activity that runs when your application starts then clear all the other activities, then have the last remaining activity finish. to do so apply the following code in ur project

Intent intent = new Intent(getApplicationContext(), FirstActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("EXIT", true);
startActivity(intent);

The above code finishes all the activities except for FirstActivity. Then we need to finish the FirstActivity's Enter the below code in Firstactivity's oncreate

if (getIntent().getBooleanExtra("EXIT", false)) {
    finish();
}

and you are done....

Have you tried setting JButton.setOpaque(true)?

JButton button = new JButton("test");
button.setBackground(Color.RED);
button.setOpaque(true);

In some distributives(CentOS/OpenSuSe,...) will work only if you set JAVA_HOME in the /etc/environment.

Works that way as well, a bit more tidy. getQuery() just returns the underlying builder, which already contains the table reference.

$browser_total_raw = DB::raw('count(*) as total');
$user_info = Usermeta::getQuery()
                     ->select('browser', $browser_total_raw)
                     ->groupBy('browser')
                     ->pluck('total','browser');

You can also use this option

#include <conio.h> 
/* run this program using the console pauser or add your own getch, system("pause") or input loop */
int main() {
   .
   .
   .
   getch(); 

   return 0;
}

onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"

Change 1000 to the number of milliseconds you want to delay.

Here's the code that worked for me.

`$('a[href*="#"]')

    .not('[href="#"]')
    .not('[href="#0"]')
    .click(function(event) {
     if (
       location.pathname.replace(/^\//, '') == this.pathname.replace(/^\//, '')
       &&
       location.hostname == this.hostname
        ) {

  var target = $(this.hash);
  target = target.length ? target : $('[name=' + this.hash.slice(1) + ']');
  if (target.length) {

    event.preventDefault();
    $('html, body').animate({
      scrollTop: target.offset().top
    }, 1000, function() {

      var $target = $(target);
      $target.focus();
      if ($target.is(":focus")) { 
        return false;
      } else {
        $target.attr('tabindex','-1'); 
        $target.focus(); 
      };
    });
    }
   }
  });

Anytime we create a timeout we should s clear it on componentWillUnmount, if it hasn't fired yet.

      let myVar;
         const Component = React.createClass({

            getInitialState: function () {
                return {position: 0};    
            },

            componentDidMount: function () {
                 myVar = setTimeout(()=> this.setState({position: 1}), 3000)
            },

            componentWillUnmount: () => {
              clearTimeout(myVar);
             };
            render: function () {
                 return (
                    <div className="component">
                        {this.state.position}
                    </div>
                 ); 
            }

        });

ReactDOM.render(
    <Component />,
    document.getElementById('main')
);

#include <windows.h>

Syntax:

Sleep (  __in DWORD dwMilliseconds   );

Usage:

Sleep (1000); //Sleeps for 1000 ms or 1 sec

The Proxy pattern might help you:

(function() {
    // log all calls to setArray
    var proxied = jQuery.fn.setArray;
    jQuery.fn.setArray = function() {
        console.log( this, arguments );
        return proxied.apply( this, arguments );
    };
})();

The above wraps its code in a function to hide the "proxied"-variable. It saves jQuery's setArray-method in a closure and overwrites it. The proxy then logs all calls to the method and delegates the call to the original. Using apply(this, arguments) guarantees that the caller won't be able to notice the difference between the original and the proxied method.

For some reason, there is no option in the create page dialogue to select a master page. I have tried both programatically declaring the MP and by updating the property in the Properties pane. – NoCarrier 13 mins ago

Chances are it is in the <@PAGE> tag where your problem is. That said, it doesnt make a difference if you are using a Web Application or not. To create a Child Page, right click on your master page in the Solution Explorer and choose Add Content Page.

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

Assuming you use the format "o" for your datetime so you have "2016-07-24T18:47:36Z", there is a very simple way to handle this.

Call DateTime.Parse("2016-07-24T18:47:36Z").ToUniversalTime().

What happens when you call DateTime.Parse("2016-07-24T18:47:36Z") is you get a DateTime set to the local timezone. So it converts it to the local time.

The ToUniversalTime() changes it to a UTC DateTime and converts it back to UTC time.

You can do that with bool query and combination of must and must_not like this:

GET index/_search
{
    "query": {
        "bool": {
            "must": [
                {"exists": {"field": "field1"}}
            ],
            "must_not": [
                {"term": {"field1": ""}}
            ]
        }
    }
}

I tested this with Elasticsearch 5.6.5 in Kibana.

The stl contains a bunch of methods that should be used dependent to the problem.

Now it contains on your data what algorithm to use. This Artikel contains a perfect table to help choosing the right algorithm.

In the special case where min max should be determined and you are using std::vector or ???* array

std::min_element
std::max_element

can be used.

curl's --data will by default send Content-Type: application/x-www-form-urlencoded in the request header. However, when using Postman's raw body mode, Postman sends Content-Type: text/plain in the request header.

So to achieve the same thing as Postman, specify -H "Content-Type: text/plain" for curl:

curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/

Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network tab :

Following two steps worked perfectly fine for me:

1. Comment out the bind address from the file /etc/mysql/my.cnf:

   #bind-address = 127.0.0.1

2. Run following query in phpMyAdmin:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;

Using PowerShell, you can execute this statement:

([system.reflection.assembly]::loadfile("C:\..\Full_Path\..\MyDLL.dll")).FullName

The output will provide the Version, Culture and PublicKeyToken as shown below:

I now recommend the use of Carbon

To get keys in HashMap, We have keySet() method which is present in java.util.Hashmap package. ex :

Map<String,String> map = new Hashmap<String,String>();
map.put("key1","value1");
map.put("key2","value2");

// Now to get keys we can use keySet() on map object
Set<String> keys = map.keySet();

Now keys will have your all keys available in map. ex: [key1,key2]

For anyone else out there wondering how to do this, I have the following solution for SQL Server 2008 R2 and later:

USE master
go
DENY VIEW ANY DATABASE TO [user]
go

This will address exactly the requirement outlined above..

You can also check for socket output stream error while writing to client socket.

out.println(output);
if(out.checkError())
{
    throw new Exception("Error transmitting data.");
}

    public void printReflectionClassNames(){
    StringBuffer buffer = new StringBuffer();
    Class clazz= buffer.getClass();
    System.out.println("Reflection on String Buffer Class");
    System.out.println("Name: "+clazz.getName());
    System.out.println("Simple Name: "+clazz.getSimpleName());
    System.out.println("Canonical Name: "+clazz.getCanonicalName());
    System.out.println("Type Name: "+clazz.getTypeName());
}

outputs:

A common use of JSON is to read data from a web server, and display the data in a web page.

This chapter will teach you how to exchange JSON data between the client and a PHP server.

PHP has some built-in functions to handle JSON.

Objects in PHP can be converted into JSON by using the PHP function json_encode():

<?php_x000D_
$myObj->name = "John";_x000D_
$myObj->age = 30;_x000D_
$myObj->city = "New York";_x000D_
_x000D_
$myJSON = json_encode($myObj);_x000D_
_x000D_
echo $myJSON;_x000D_
?>

What specific errors are you seeing?

Something like this could work better:

<script type="text/javascript">

//now add markers
 @foreach (var item in Model) {
    <text>
      var markerlatLng = new google.maps.LatLng(@Model.Latitude, @Model.Longitude);
      var title = '@(Model.Title)';
      var description = '@(Model.Description)';
      var contentString = '<h3>' + title + '</h3>' + '<p>' + description + '</p>'
    </text>
}
</script>

Note that you need the magical <text> tag after the foreach to indicate that Razor should switch into markup mode.

When using "jsonp", you would basically be returning data wrapped in a function call, something like

jsonpCallback([{"id":1,"value":"testing"},{"id":2,"value":"test again"}])
where the function/callback name is 'jsonpCallback'.

If you have access to the server, please first verify that the response is in the correct "jsonp" format

For such a response coming from the server, you would need to specify something in the ajax call as well, something like

jsonpCallback: "jsonpCallback",  in your ajax call

Please note that the name of the callback does not need to be "jsonpCallback" its just a name picked as an example but it needs to match the name(wrapping) done on the server side.

My first guess to your problem is that the response from the server is not what it should be.

ColumnNames is a property of type List<String> so when you are setting up you need to pass a List<String> in the Returns call as an argument (or a func which return a List<String>)

But with this line you are trying to return just a string

input.SetupGet(x => x.ColumnNames).Returns(temp[0]);

which is causing the exception.

Change it to return whole list:

Cookies are stored in browser as a text file format.It is stored limit amount of data.It is only allowing 4kb[4096bytes].$_COOKIE variable not will hold multiple cookies with the same name

we can accessing the cookies values in easily.So it is less secure.The setcookie() function must appear BEFORE the

<html> 

tag.

Sessions are stored in server side.It is stored unlimit amount of data.It is holding the multiple variable in sessions. we cannot accessing the cookies values in easily.So it is more secure.

You're thinking too complicated. It's actually just $('#'+openaddress).

Use LOWER function to convert the strings to lower case before comparing.

Try this:

SELECT id 
  FROM groups
 WHERE LOWER(name)=LOWER('Administrator')

This is an old question, but here is something that might help someone.

From the official docs:

Django provides tools for performing URL reversing that match the different layers where URLs are needed: In templates: Using the url template tag. In Python code: Using the reverse() function. In higher level code related to handling of URLs of Django model instances: The get_absolute_url() method.

Eg. in templates (url tag)

<a href="{% url 'news-year-archive' 2012 %}">2012 Archive</a>

Eg. in python code (using the reverse function)

return HttpResponseRedirect(reverse('news-year-archive', args=(year,)))

Here I am posting you the some code example which record good quality of sound using AudioRecord API.

Happy Coding !!

Follow this simple steps; (Works on MAC OS too)

1. Open terminal and run sudo mongod

2. Open a new terminal tab(Don't close step 1 tab) and run sudo mongo

That's all

If you have a foreign key definition in some table and the name of the foreign key is used elsewhere as another foreign key you will have this error.

You can also change the port from Gruntfile.js and run again.

Follow the below steps to unlock the handlers at the parent level:

1) In the connections tree(in IIS), go to your server node and then to your website.

2) For the website, in the right window you will see configuration editor under Management.

3) Double click on the configuration editor.

4) In the window that opens, on top you will find a drop down for sections. Choose "system.webServer/handlers" from the drop down.

5) On the right side, there is another drop down. Choose "ApplicationHost.Config "

6) On the right most pane, you will find "Unlock Section" under "Section" heading. Click on that.

7) Once the handlers at the applicationHost is unlocked, your website should run fine.

There is a much simpler solution that will take a minute.

1. In google play console, select Release management -> App signing
2. Choose the first option, the one with Generate encrypted private key with Android Studio (or something like that; I cannot turn back to see that page anymore)
3. In Android Studio generate your Android App Bundle (.aap file) from Build -> Generate Signed Bundle / APK..., choose Android App Bundle option and don't forget to check Export Encrypted key (needed to enroll your app Google Play App signing) option. If you do not have a keystore generated, generate one ad-hoc.
4. Now the "tricky" part. After the .aap is generated, Android Studio will pop up a notification in the bottom right corner containing a path to the location where the .aap file is saved. In the same notification, if you will expand it you will find another link to the path where the private key was saved (called private_key.pepk). If you miss this notification, don't worry, just open Event Log window by clicking the Event Log button on the bottom right side and you will find the same info. Open that location.For me was C:\Users\yourUser\.android

5. Go back in browser and press APP SIGNING PRIVATE KEY button and browse to the private key location on your computer.

Done!

Now you are able to upload your release that you generated earlier :) Good luck!

You can use .ndim for dimension and .shape to know the exact dimension

var = np.array([[1,2,3,4,5,6], [1,2,3,4,5,6]])

var.ndim
# displays 2

var.shape
# display 6, 2

You can change the dimension using .reshape function

var = np.array([[1,2,3,4,5,6], [1,2,3,4,5,6]]).reshape(3,4)

var.ndim
#display 2

var.shape
#display 3, 4

I've gotten lots of information here so I wanted to post a solution I discovered.

The problem: Getting JSON data from Javascript on the browser, to the server, and having PHP successfully parse it.

Environment: Javascript in a browser (Firefox) on Windows. LAMP server as remote server: PHP 5.3.2 on Ubuntu.

What works (version 1):
1) JSON is just text. Text in a certain format, but just a text string.

2) In Javascript, var str_json = JSON.stringify(myObject) gives me the JSON string.

3) I use the AJAX XMLHttpRequest object in Javascript to send data to the server:

request= new XMLHttpRequest()
request.open("POST", "JSON_Handler.php", true)
request.setRequestHeader("Content-type", "application/json")
request.send(str_json)
[... code to display response ...]

4) On the server, PHP code to read the JSON string:

$str_json = file_get_contents('php://input');

This reads the raw POST data. $str_json now contains the exact JSON string from the browser.

What works (version 2):
1) If I want to use the "application/x-www-form-urlencoded" request header, I need to create a standard POST string of "x=y&a=b[etc]" so that when PHP gets it, it can put it in the $_POST associative array. So, in Javascript in the browser:

var str_json = "json_string=" + (JSON.stringify(myObject))

PHP will now be able to populate the $_POST array when I send str_json via AJAX/XMLHttpRequest as in version 1 above.

Displaying the contents of $_POST['json_string'] will display the JSON string. Using json_decode() on the $_POST array element with the json string will correctly decode that data and put it in an array/object.

The pitfall I ran into:
Initially, I tried to send the JSON string with the header of application/x-www-form-urlencoded and then tried to immediately read it out of the $_POST array in PHP. The $_POST array was always empty. That's because it is expecting data of the form yval=xval&[rinse_and_repeat]. It found no such data, only the JSON string, and it simply threw it away. I examined the request headers, and the POST data was being sent correctly.

Similarly, if I use the application/json header, I again cannot access the sent data via the $_POST array. If you want to use the application/json content-type header, then you must access the raw POST data in PHP, via php://input, not with $_POST.

References:
1) How to access POST data in PHP: How to access POST data in PHP?
2) Details on the application/json type, with some sample objects which can be converted to JSON strings and sent to the server: http://www.ietf.org/rfc/rfc4627.txt

Normally there is no way to break an "each" loop in javascript. What can be done usually is to use "short circuit" method.

    array.forEach(function(item) {_x000D_
      // if the condition is not met, move on to the next round of iteration._x000D_
      if (!condition) return;_x000D_
_x000D_
      // if the condition is met, do your logic here_x000D_
      console.log('do stuff.')_x000D_
    }

If you google. "Count down for loop python" you get these, which are pretty accurate.

how to loop down in python list (countdown)
Loop backwards using indices in Python?

I recommend doing minor searches before posting. Also "Learn Python The Hard Way" is a good place to start.

Based on the property names it looks like you are trying to convert a string to a date by assignment:

claimantAuxillaryRecord.TPOCDate2 = tpoc2[0].ToString();

It is probably due to the current UI culture and therefore it cannot interpret the date string correctly when assigned.

There are several ways to implement modules in JavaScript. Here are the two most popular ones:

ES6 Modules

Browsers do not support this moduling system yet, so in order for you to use this syntax you must use a bundler like Webpack. Using a bundler is better anyway because this can combine all of your different files into a single (or a couple of related) files. This will serve the files from the server to the client faster because each HTTP request has some associated overhead accompanied with it. Thus by reducing the overall HTTP request we improve the performance. Here is an example of ES6 modules:

// main.js file

export function add (a, b) {
  return a + b;
}

export default function multiply (a, b) {
  return a * b;
}


// test.js file

import {add}, multiply from './main';   // For named exports between curly braces {export1, export2}
                                        // For default exports without {}

console.log(multiply(2, 2));  // logs 4

console.log(add(1, 2));  // logs 3

CommonJS (used in Node.js)

This moduling system is used in Node.js. You basically add your exports to an object which is called module.exports. You then can access this object via a require('modulePath'). Important here is to realize that these modules are being cached, so if you require() a certain module twice it will return the already created module.

// main.js file

function add (a, b) {
  return a + b;
}

module.exports = add;  // Here we add our 'add' function to the exports object


// test.js file

const add = require('./main');

console.log(add(1,2));  // logs 3

break; is what you need to break out of any looping statement like for, while or do-while.

In your case, its going to be like this:-

for(int x = 10; x < 20; x++) {
         // The below condition can be present before or after your sysouts, depending on your needs.
         if(x == 15){
             break; // A unlabeled break is enough. You don't need a labeled break here.
         }
         System.out.print("value of x : " + x );
         System.out.print("\n");
}

Try this:

import java.util.*;

public class SimpleCacheManager {

    private static SimpleCacheManager instance;
    private static Object monitor = new Object();
    private Map<String, Object> cache = Collections.synchronizedMap(new HashMap<String, Object>());

    private SimpleCacheManager() {
    }

    public void put(String cacheKey, Object value) {
        cache.put(cacheKey, value);
    }

    public Object get(String cacheKey) {
        return cache.get(cacheKey);
    }

    public void clear(String cacheKey) {
        cache.put(cacheKey, null);
    }

    public void clear() {
        cache.clear();
    }

    public static SimpleCacheManager getInstance() {
        if (instance == null) {
            synchronized (monitor) {
                if (instance == null) {
                    instance = new SimpleCacheManager();
                }
            }
        }
        return instance;
    }

}

This answer is just a more detailed version of Bradford Medeiros's solution, which for me as well turned out to be the best answer, so the credit goes to him.

In his answer, he explains WHAT to do (named pipes) but not exactly HOW to do it.

I have to admit I didn't know what are named pipes at the time I read his solution. So I struggled to implement it (while it's actually really simple), but I did succeed, so I'm happy to help by explaining how I did it. So the point of my answer is just detailing the commands you need to run in order to get it working, but again, credit goes to him.

PART 1 - Testing the named pipe concept without docker

On the main host, chose the folder where you want to put your named pipe file, for instance /path/to/pipe/ and a pipe name, for instance mypipe, and then run:

mkfifo /path/to/pipe/mypipe

The pipe is created. Type

ls -l /path/to/pipe/mypipe 

And check the access rights start with "p", such as

prw-r--r-- 1 root root 0 mypipe

Now run:

tail -f /path/to/pipe/mypipe

The terminal is now waiting for data to be sent into this pipe

Now open another terminal window.

And then run:

echo "hello world" > /path/to/pipe/mypipe

Check the first terminal (the one with tail -f), it should display "hello world"

PART 2 - Run commands through the pipe

On the host container, instead of running tail -f which just outputs whatever is sent as input, run this command that will execute it as commands:

eval "$(cat /path/to/pipe/mypipe)"

Then, from the other terminal, try running:

echo "ls -l" > /path/to/pipe/mypipe

Go back to the first terminal and you should see the result of the ls -l command.

PART 3 - Make it listen forever

You may have noticed that in the previous part, right after ls -l output is displayed, it stops listening for commands.

Instead of eval "$(cat /path/to/pipe/mypipe)", run:

while true; do eval "$(cat /path/to/pipe/mypipe)"; done

(you can nohup that)

Now you can send unlimited number of commands one after the other, they will all be executed, not just the first one.

PART 4 - Make it work even when reboot happens

The only caveat is if the host has to reboot, the "while" loop will stop working.

To handle reboot, here what I've done:

Put the while true; do eval "$(cat /path/to/pipe/mypipe)"; done in a file called execpipe.sh with #!/bin/bash header

Don't forget to chmod +x it

Add it to crontab by running

crontab -e

And then adding

@reboot /path/to/execpipe.sh

At this point, test it: reboot your server, and when it's back up, echo some commands into the pipe and check if they are executed. Of course, you aren't able to see the output of commands, so ls -l won't help, but touch somefile will help.

Another option is to modify the script to put the output in a file, such as:

while true; do eval "$(cat /path/to/pipe/mypipe)" &> /somepath/output.txt; done

Now you can run ls -l and the output (both stdout and stderr using &> in bash) should be in output.txt.

PART 5 - Make it work with docker

If you are using both docker compose and dockerfile like I do, here is what I've done:

Let's assume you want to mount the mypipe's parent folder as /hostpipe in your container

Add this:

VOLUME /hostpipe

in your dockerfile in order to create a mount point

Then add this:

volumes:
   - /path/to/pipe:/hostpipe

in your docker compose file in order to mount /path/to/pipe as /hostpipe

Restart your docker containers.

PART 6 - Testing

Exec into your docker container:

docker exec -it <container> bash

Go into the mount folder and check you can see the pipe:

cd /hostpipe && ls -l

Now try running a command from within the container:

echo "touch this_file_was_created_on_main_host_from_a_container.txt" > /hostpipe/mypipe

And it should work!

WARNING: If you have an OSX (Mac OS) host and a Linux container, it won't work (explanation here https://stackoverflow.com/a/43474708/10018801 and issue here https://github.com/docker/for-mac/issues/483 ) because the pipe implementation is not the same, so what you write into the pipe from Linux can be read only by a Linux and what you write into the pipe from Mac OS can be read only by a Mac OS (this sentence might not be very accurate, but just be aware that a cross-platform issue exists).

For instance, when I run my docker setup in DEV from my Mac OS computer, the named pipe as explained above does not work. But in staging and production, I have Linux host and Linux containers, and it works perfectly.

PART 7 - Example from Node.JS container

Here is how I send a command from my node js container to the main host and retrieve the output:

const pipePath = "/hostpipe/mypipe"
const outputPath = "/hostpipe/output.txt"
const commandToRun = "pwd && ls-l"

console.log("delete previous output")
if (fs.existsSync(outputPath)) fs.unlinkSync(outputPath)

console.log("writing to pipe...")
const wstream = fs.createWriteStream(pipePath)
wstream.write(commandToRun)
wstream.close()

console.log("waiting for output.txt...") //there are better ways to do that than setInterval
let timeout = 10000 //stop waiting after 10 seconds (something might be wrong)
const timeoutStart = Date.now()
const myLoop = setInterval(function () {
    if (Date.now() - timeoutStart > timeout) {
        clearInterval(myLoop);
        console.log("timed out")
    } else {
        //if output.txt exists, read it
        if (fs.existsSync(outputPath)) {
            clearInterval(myLoop);
            const data = fs.readFileSync(outputPath).toString()
            if (fs.existsSync(outputPath)) fs.unlinkSync(outputPath) //delete the output file
            console.log(data) //log the output of the command
        }
    }
}, 300);

$total = count($_FILES['txt_gallery']['name']);
            $filename_arr = [];
            $filename_arr1 = [];
            for( $i=0 ; $i < $total ; $i++ ) {
              $tmpFilePath = $_FILES['txt_gallery']['tmp_name'][$i];
              if ($tmpFilePath != ""){
                $newFilePath = "../uploaded/" .date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
                $newFilePath1 = date('Ymdhis').$i.$_FILES['txt_gallery']['name'][$i];
                if(move_uploaded_file($tmpFilePath, $newFilePath)) {
                  $filename_arr[] = $newFilePath;
                  $filename_arr1[] = $newFilePath1;

                }
              }
            }
            $file_names = implode(',', $filename_arr1);
            var_dump($file_names); exit;
