Here's the obligatory dplyr answer in case somebody wants to do this with the pipe.

test %>% 
    select(sort(names(.)))

Annotation Approach

@ComponentScan({ "x.y.z", "x.y.z.dao" })

On Windows, you can also use the Win32 File Namespace prefixed with \\?\ to refer to your local directories:

\\?\C:\my_dir

See this answer for description.

You're overcomplicating things:

var e = $('<div style="display:block; float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
e.attr('id', 'myid');
$('#box').append(e);

For example: http://jsfiddle.net/ambiguous/Dm5J2/

Here is a function that will load CSS files with a success or failure callback. The failure callback will be called just once, if one or more resources fail to load. I think this approach is better than some of the other solutions because inserting a element into the DOM with an HREF causes an additional browser request (albeit, the request will likely come from cache, depending on response headers).

function loadCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            return $.get(url, function(css) {
                $("<style>" + css + "</style>").appendTo("head");
            });
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

Usage as so:

loadCssFiles(["https://test.com/style1.css", "https://test.com/style2.css",],
    function() {
    alert("All resources loaded");
}, function() {
    alert("One or more resources failed to load");
});

Here is another function that will load both CSS and javascript files:

function loadJavascriptAndCssFiles(urls, successCallback, failureCallback) {

    $.when.apply($,
        $.map(urls, function(url) {
            if(url.endsWith(".css")) {
                return $.get(url, function(css) {
                    $("<style>" + css + "</style>").appendTo("head");
                });
            } else {
                return $.getScript(url);
            }
        })
    ).then(function() {
        if (typeof successCallback === 'function') successCallback();
    }).fail(function() {
        if (typeof failureCallback === 'function') failureCallback();
    });

}

There is the $.parseXML function for this: http://api.jquery.com/jQuery.parseXML/

You can use it like this:

var xml = $.parseXML(yourfile.xml),
  $xml = $( xml ),
  $test = $xml.find('test');

console.log($test.text());

If you really want an object, you need a plugin for that. This plugin for instance, will convert your XML to JSON: http://www.fyneworks.com/jquery/xml-to-json/

When using Class based views, another option is to use the dispatch method. https://docs.djangoproject.com/en/2.2/ref/class-based-views/base/

Example Code:

Settings.py

LOGIN_URL = 'login'
LOGIN_REDIRECT_URL = 'home'

urls.py

from django.urls import path
from django.contrib.auth import views as auth_views
urlpatterns = [
path('', HomeView.as_view(), name='home'),
path('login/', auth_views.LoginView.as_view(),name='login'),
path('logout/', auth_views.LogoutView.as_view(), name='logout'),
]

views.py

from django.utils.decorators import method_decorator
from django.contrib.auth.decorators import login_required
from django.views.generic import View
from django.shortcuts import redirect

@method_decorator([login_required], name='dispatch')
class HomeView(View):
    model = models.User

    def dispatch(self, request, *args, **kwargs):
        if not request.user.is_authenticated:
            return redirect('login')
        elif some-logic:
            return redirect('some-page') #needs defined as valid url
        return super(HomeView, self).dispatch(request, *args, **kwargs)

Pass arguments from the command line

// npm install --save-dev gulp gulp-if gulp-uglify minimist

var gulp = require('gulp');
var gulpif = require('gulp-if');
var uglify = require('gulp-uglify');

var minimist = require('minimist');

var knownOptions = {
  string: 'env',
  default: { env: process.env.NODE_ENV || 'production' }
};

var options = minimist(process.argv.slice(2), knownOptions);

gulp.task('scripts', function() {
  return gulp.src('**/*.js')
    .pipe(gulpif(options.env === 'production', uglify())) // only minify in production
    .pipe(gulp.dest('dist'));
});

Then run gulp with:

$ gulp scripts --env development

Source

With ES 6 arrow function

let someArray = [
                 {name:"Kristian", lines:"2,5,10"},
                 {name:"John", lines:"1,19,26,96"}
                ];
let arrayToRemove={name:"Kristian", lines:"2,5,10"};
someArray=someArray.filter((e)=>e.name !=arrayToRemove.name && e.lines!= arrayToRemove.lines)

For the sources on dependency level ( pom.xml) you can add :

<classifier>sources</classifier>

Post-increment:

int x, y, z;

x = 1;
y = x++; //this means: y is assigned the x value first, then increase the value of x by 1. Thus y is 1;
z = x; //the value of x in this line and the rest is 2 because it was increased by 1 in the above line. Thus z is 2.

Pre-increment:

int x, y, z;

x = 1;
y = ++x; //this means: increase the value of x by 1 first, then assign the value of x to y. The value of x in this line and the rest is 2. Thus y is 2.
z = x; //the value of x in this line is 2 as stated above. Thus z is 2.

You can use something like this

if ($("#formID input:checkbox:checked").length > 0)
{
    // any one is checked
}
else
{
   // none is checked
}

\l - Display database
\c - Connect to database
\dn - List schemas
\dt - List tables inside public schemas
\dt schema1. - List tables inside particular schemas. For eg: 'schema1'.

For example, let's say that you want to create a random number between 50 and 60, you can use one of the following methods.

new Random().nextInt()%6 +55

new Random().nextInt()%6 returns a value between -5 and 5. and when you add it to 55 you can get values between 50 and 60

Second method:

Math.abs(new Random().nextInt()%11) +50

Math.abs(new Random().nextInt()%11) creates a value between 0 and 10. Later you can add 50 which in the will give you a value between 50 and 60

This exact functionality (3 second glow to highlight a message) is implemented in the jQuery UI as the highlight effect

Color and duration are variable

Check service dependencies if they are disabled.

Set those dependencies to Automatic, Start them and it should work.

If you're using pure JS you can simply do it like:

var input = document.getElementById('myInput');

if(input.value.length == 0)
    input.value = "Empty";

Here's a demo: http://jsfiddle.net/nYtm8/

Although approved answer is correct, I want to show a bit different approach (based on this answer).

Vscode can automatically choose correct anaconda environment if you start vscode from it. Just add to user/workspace settings:

{
    "python.pythonPath": "C:/<proper anaconda path>/Anaconda3/envs/${env:CONDA_DEFAULT_ENV}/python"
}

It works on Windows, macOS and probably Unix. Further read on variable substitution in vscode: here.

From inside mysql, you could use search/replace using a text editor:

SELECT table_schema, table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

Note: You should probably ignore information_schema and mysql because "The mysql and information_schema databases, that implement some of the MySQL internals, still use MyISAM. In particular, you cannot switch the grant tables to use InnoDB." ( http://dev.mysql.com/doc/refman/5.5/en/innodb-default-se.html )

In any case, note the tables to ignore and run:

SELECT table_name FROM INFORMATION_SCHEMA.TABLES WHERE engine = 'myisam';

Now just copy/paste that list into your text editor and search/replace "|" with "ALTER TABLE" etc.

You'll then have a list like this you can simply paste into your mysql terminal:

ALTER TABLE arth_commentmeta           ENGINE=Innodb;
ALTER TABLE arth_comments              ENGINE=Innodb;
ALTER TABLE arth_links                 ENGINE=Innodb;
ALTER TABLE arth_options               ENGINE=Innodb;
ALTER TABLE arth_postmeta              ENGINE=Innodb;
ALTER TABLE arth_posts                 ENGINE=Innodb;
ALTER TABLE arth_term_relationships    ENGINE=Innodb;
ALTER TABLE arth_term_taxonomy         ENGINE=Innodb;
ALTER TABLE arth_terms                 ENGINE=Innodb;
ALTER TABLE arth_usermeta              ENGINE=Innodb;

If your text editor can't do this easily, here's another solution for getting a similar list (that you can paste into mysql) for just one prefix of your database, from linux terminal:

mysql -u [username] -p[password] -B -N -e 'show tables like "arth_%"' [database name] | xargs -I '{}' echo "ALTER TABLE {} ENGINE=INNODB;"

You can change

Range("B3:B65536").Copy Destination:=Sheets("DB").Range("B" & lastrow)

to

Range("B3:B65536").Copy 
Sheets("DB").Range("B" & lastrow).PasteSpecial xlPasteValues

BTW, if you have xls file (excel 2003), you would get an error if your lastrow would be greater 3.

Try to use this code instead:

Sub Get_Data()
    Dim lastrowDB As Long, lastrow As Long
    Dim arr1, arr2, i As Integer

    With Sheets("DB")
        lastrowDB = .Cells(.Rows.Count, "A").End(xlUp).Row + 1
    End With

    arr1 = Array("B", "C", "D", "E", "F", "AH", "AI", "AJ", "J", "P", "AF")
    arr2 = Array("B", "A", "C", "P", "D", "E", "G", "F", "H", "I", "J")

    For i = LBound(arr1) To UBound(arr1)
        With Sheets("Sheet1")
             lastrow = Application.Max(3, .Cells(.Rows.Count, arr1(i)).End(xlUp).Row)
             .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
             Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues
        End With
    Next
    Application.CutCopyMode = False
End Sub

Note, above code determines last non empty row on DB sheet in column A (variable lastrowDB). If you need to find lastrow for each destination column in DB sheet, use next modification:

For i = LBound(arr1) To UBound(arr1)
   With Sheets("DB")
       lastrowDB = .Cells(.Rows.Count, arr2(i)).End(xlUp).Row + 1
   End With

   ' NEXT CODE

Next

You could also use next approach instead Copy/PasteSpecial. Replace

.Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Copy
Sheets("DB").Range(arr2(i) & lastrowDB).PasteSpecial xlPasteValues

with

Sheets("DB").Range(arr2(i) & lastrowDB).Resize(lastrow - 2).Value = _
      .Range(.Cells(3, arr1(i)), .Cells(lastrow, arr1(i))).Value

Close buffer without closing the window

If you want to close a buffer without destroying your window layout (current layout based on splits), you can use a Plugin like bbye. Based on this, you can just use

:Bdelete (instead of :bdelete)
:Bwipeout (instead of :bwipeout)

Or just create a mapping in your .vimrc for easier access like

:nnoremap <Leader>q :Bdelete<CR>

Advantage over vim's :bdelete and :bwipeout

From the plugin's documentation:

• Close and remove the buffer.
• Show another file in that window.
• Show an empty file if you've got no other files open.
• Do not leave useless [no file] buffers if you decide to edit another file in that window.
• Work even if a file's open in multiple windows.
• Work a-okay with various buffer explorers and tabbars.

:bdelete vs :bwipeout

From the plugin's documentation:

Vim has two commands for closing a buffer: :bdelete and :bwipeout. The former removes the file from the buffer list, clears its options, variables and mappings. However, it remains in the jumplist, so Ctrl-o takes you back and reopens the file. If that's not what you want, use :bwipeout or Bbye's equivalent :Bwipeout where you would've used :bdelete.

The function match works on vectors:

x <- sample(1:10)
x
# [1]  4  5  9  3  8  1  6 10  7  2
match(c(4,8),x)
# [1] 1 5

match only returns the first encounter of a match, as you requested. It returns the position in the second argument of the values in the first argument.

For multiple matching, %in% is the way to go:

x <- sample(1:4,10,replace=TRUE)
x
# [1] 3 4 3 3 2 3 1 1 2 2
which(x %in% c(2,4))
# [1]  2  5  9 10

%in% returns a logical vector as long as the first argument, with a TRUE if that value can be found in the second argument and a FALSE otherwise.

Don't use Model::latest()->first(); because if your collection has multiple rows created at the same timestamp (this will happen when you use database transaction DB::beginTransaction(); and DB::commit()) then the first row of the collection will be returned and obviously this will not be the last row.

Suppose row with id 11, 12, 13 are created using transaction then all of them will have the same timestamp so what you will get by Model::latest()->first(); is the row with id: 11.

I just had this problem

1. Having multiple user using the same repo caused the problem
2. Logout evey other user using the repo

Hope this helps

I've been frustrated for long by Windows code page issues, and the C programs portability and localisation issues they cause. The previous posts have detailed the issues at length, so I'm not going to add anything in this respect.

To make a long story short, eventually I ended up writing my own UTF-8 compatibility library layer over the Visual C++ standard C library. Basically this library ensures that a standard C program works right, in any code page, using UTF-8 internally.

This library, called MsvcLibX, is available as open source at https://github.com/JFLarvoire/SysToolsLib. Main features:

• C sources encoded in UTF-8, using normal char[] C strings, and standard C library APIs.
• In any code page, everything is processed internally as UTF-8 in your code, including the main() routine argv[], with standard input and output automatically converted to the right code page.
• All stdio.h file functions support UTF-8 pathnames > 260 characters, up to 64 KBytes actually.
• The same sources can compile and link successfully in Windows using Visual C++ and MsvcLibX and Visual C++ C library, and in Linux using gcc and Linux standard C library, with no need for #ifdef ... #endif blocks.
• Adds include files common in Linux, but missing in Visual C++. Ex: unistd.h
• Adds missing functions, like those for directory I/O, symbolic link management, etc, all with UTF-8 support of course :-).

More details in the MsvcLibX README on GitHub, including how to build the library and use it in your own programs.

The release section in the above GitHub repository provides several programs using this MsvcLibX library, that will show its capabilities. Ex: Try my which.exe tool with directories with non-ASCII names in the PATH, searching for programs with non-ASCII names, and changing code pages.

Another useful tool there is the conv.exe program. This program can easily convert a data stream from any code page to any other. Its default is input in the Windows code page, and output in the current console code page. This allows to correctly view data generated by Windows GUI apps (ex: Notepad) in a command console, with a simple command like: type WINFILE.txt | conv

This MsvcLibX library is by no means complete, and contributions for improving it are welcome!

Quoting the README at https://github.com/mhammond/pywin32:

By far the easiest way to use pywin32 is to grab binaries from the most recent release

Just download the installer for your version of Python from https://github.com/mhammond/pywin32/releases and run it, and you're done.

According to MSDN:

An operating-system ThreadId has no fixed relationship to a managed thread, because an unmanaged host can control the relationship between managed and unmanaged threads. Specifically, a sophisticated host can use the CLR Hosting API to schedule many managed threads against the same operating system thread, or to move a managed thread between different operating system threads.

So basically, the Thread object does not necessarily correspond to an OS thread - which is why it doesn't have the native ID exposed.

I think you need a body for the getAppContext() method:

public static Context getAppContext()
   return MyApplication.context; 

If you are using Gradle, you could include the dependency like this:

repositories {
    mavenCentral()
}

dependencies {
    compile group: 'com.google.code.findbugs', name: 'jsr305', version: '3.0.0'
}

If you want to find the create statement for a table without using pg_dump, This query might work for you (change 'tablename' with whatever your table is called):

SELECT                                          
  'CREATE TABLE ' || relname || E'\n(\n' ||
  array_to_string(
    array_agg(
      '    ' || column_name || ' ' ||  type || ' '|| not_null
    )
    , E',\n'
  ) || E'\n);\n'
from
(
  SELECT 
    c.relname, a.attname AS column_name,
    pg_catalog.format_type(a.atttypid, a.atttypmod) as type,
    case 
      when a.attnotnull
    then 'NOT NULL' 
    else 'NULL' 
    END as not_null 
  FROM pg_class c,
   pg_attribute a,
   pg_type t
   WHERE c.relname = 'tablename'
   AND a.attnum > 0
   AND a.attrelid = c.oid
   AND a.atttypid = t.oid
 ORDER BY a.attnum
) as tabledefinition
group by relname;

when called directly from psql, it is usefult to do:

\pset linestyle old-ascii

Also, the function generate_create_table_statement in this thread works very well.

The closest equivalent to your VB would be (see this):

Convert.IsDBNull()

But there are a number of ways to do this, and most are linked from here

I'm using ui-bootstrap-tpls.js and what worked for me is that I searched in the whole project for fade and found 3 places where this was being set in the mentioned file.

I went through the find results and saw that 2 of the changes were being done on the modal and the other one was being set on the tool tip animation. Note the difference in below code

'uib-modal-animation-class': 'fade'
'tooltip-animation-class="fade"'

What I did to solve the issue was to add the show class for the uib-modal

'uib-modal-animation-class': 'fade show'

absolute positioning is evil... this solution doesn't take into account window size. If you resize the browser window, your div will be out of place!

You can use the callback result of showSoftInput() and hideSoftInput() to check for the status of the keyboard. Full details and example code at

The solution by user1236048 is correct, but the key point isn't called out. In your POJO classes used for the table's observable list, you not only have to set getter and setter methods, but a new one called Property. In Oracle's tableview tutorial (http://docs.oracle.com/javafx/2/ui_controls/table-view.htm), they left that key part off!

Here's what the Person class should look like:

public static class Person {

    private final SimpleStringProperty firstName;
    private final SimpleStringProperty lastName;
    private final SimpleStringProperty email;

    private Person(String fName, String lName, String email) {
        this.firstName = new SimpleStringProperty(fName);
        this.lastName = new SimpleStringProperty(lName);
        this.email = new SimpleStringProperty(email);
    }

    public String getFirstName() {
        return firstName.get();
    }

    public void setFirstName(String fName) {
        firstName.set(fName);
    }

    public SimpleStringProperty firstNameProperty(){
        return firstName;
    }

    public String getLastName() {
        return lastName.get();
    }

    public void setLastName(String fName) {
        lastName.set(fName);
    }

    public SimpleStringProperty lastNameProperty(){
        return lastName;
    }

    public String getEmail() {
        return email.get();
    }

    public void setEmail(String fName) {
        email.set(fName);
    }

    public SimpleStringProperty emailProperty(){
            return email;
        }

}

Duplicate your table into a table to be archived:

SELECT * INTO ArchiveTable FROM MyTable

Delete all entries in your table:

DELETE * FROM MyTable

You can index into a string in C# like an array, and you get the character at that index.

Example:

In Java, you would say

str.charAt(8);

In C#, you would say

str[8];

The JOIN statements are also part of the FROM clause, more formally a join_type is used to combine two from_item's into one from_item, multiple one of which can then form a comma-separated list after the FROM. See http://www.postgresql.org/docs/9.1/static/sql-select.html .

So the direct solution to your problem is:

SELECT something
FROM
    master as parent LEFT JOIN second as parentdata
        ON parent.secondary_id = parentdata.id,
    master as child LEFT JOIN second as childdata
        ON child.secondary_id = childdata.id
WHERE parent.id = child.parent_id AND parent.parent_id = 'rootID'

A better option would be to only use JOIN's, as it has already been suggested.

well, I know that I'm a bit too late, but I tried all of your solutions and with no success! So here is how I managed to do it. First of all, I'm working on an Asp.Net MVC project. The Only thing I changed was in my c# method getInvitation:

public ActionResult getInvitation (Guid s_ID)
{
    using (var db = new cRM_Verband_BWEntities())
    {
        var listSidsMit = (from data in db.TERMINEINLADUNGEN where data.RECID_KOMMUNIKATIONEN == s_ID select data.RECID_MITARBEITER.ToString()).ToArray();
        return Json(listSidsMit);
    }
}

SuccessFunction in JS :

function successFunction(result) {
    console.log(result);
}

I changed the Method Type from string[] to ActionResult and of course at the end I wrapped my array listSidsMit with the Json method.

The above works but this does not. Note the ON DELETE CASCADE

CREATE DATABASE t;
USE t;

CREATE TABLE parent (id INT NOT NULL,
                 PRIMARY KEY (id)
) ENGINE=INNODB;

CREATE TABLE child (id INT NULL, 
                parent_id INT NULL,
                FOREIGN KEY (parent_id) REFERENCES parent(id) ON DELETE CASCADE

) ENGINE=INNODB;


INSERT INTO child (id, parent_id) VALUES (1, NULL);
-- Query OK, 1 row affected (0.01 sec)

var div = $('<div/>');
div.append('Hello World!');

Is the shortest/easiest way to create a DIV element in jQuery.

you could either use

SELECT PARSENAME('$'+ Convert(varchar,Convert(money,@MoneyValue),1),2)

or

SELECT CurrencyNoDecimals = '$'+ LEFT( CONVERT(varchar, @MoneyValue,1),    
       LEN (CONVERT(varchar, @MoneyValue,1)) - 2)

I was running into the same issue but was able to package all dependencies into my jar file using the Maven Shade Plugin

Don't worry... Its much easy to solve your problem. Just SET you SDK-LOCATION and JDK-LOCATION.

• Click on Configure ( As Soon Android studio open )
• Click Project Default
• Click Project Structure

• Clik Android Sdk Location

• Select & Browse your Android SDK Location (Like: C:\Android\sdk)

• Uncheck USE EMBEDDED JDK LOCATION

• Set & Browse JDK Location, Like C:\Program Files\Java\jdk1.8.0_121

It's worth noting that the QuerySet.values_list() method doesn't actually return a list, but an object of type django.db.models.query.ValuesListQuerySet, in order to maintain Django's goal of lazy evaluation, i.e. the DB query required to generate the 'list' isn't actually performed until the object is evaluated.

Somewhat irritatingly, though, this object has a custom __repr__ method which makes it look like a list when printed out, so it's not always obvious that the object isn't really a list.

The exception in the question is caused by the fact that custom objects cannot be serialized in JSON, so you'll have to convert it to a list first, with...

my_list = list(self.get_queryset().values_list('code', flat=True))

...then you can convert it to JSON with...

json_data = json.dumps(my_list)

You'll also have to place the resulting JSON data in an HttpResponse object, which, apparently, should have a Content-Type of application/json, with...

response = HttpResponse(json_data, content_type='application/json')

...which you can then return from your function.

To check if the index is defined: isset($something['say'])

For me the better approach is that:

s.split('mango', 1)[-1]

...because if happens that occurrence is not in the string you'll get "IndexError: list index out of range".

Therefore -1 will not get any harm cause number of occurrences is already set to one.

The previous answers either suggest custom renderers or require you to keep track of the selected item either in your data objects or otherwise. This isn't really required, there is a way to link to the functioning of the ListView in a platform agnostic way. This can then be used to change the selected item in any way required. Colors can be modified, different parts of the cell shown or hidden depending on the selected state.

Let's add an IsSelected property to our ViewCell. There is no need to add it to the data object; the listview selects the cell, not the bound data.

public partial class SelectableCell : ViewCell {

  public static readonly BindableProperty IsSelectedProperty = BindableProperty.Create(nameof(IsSelected), typeof(bool), typeof(SelectableCell), false, propertyChanged: OnIsSelectedPropertyChanged);
  public bool IsSelected {
    get => (bool)GetValue(IsSelectedProperty);
    set => SetValue(IsSelectedProperty, value);
  }

  // You can omit this if you only want to use IsSelected via binding in XAML
  private static void OnIsSelectedPropertyChanged(BindableObject bindable, object oldValue, object newValue) {
    var cell = ((SelectableCell)bindable);
    // change color, visibility, whatever depending on (bool)newValue
  }

  // ...
}

To create the missing link between the cells and the selection in the list view, we need a converter (the original idea came from the Xamarin Forum):

public class IsSelectedConverter : IValueConverter {
  public object Convert(object value, Type targetType, object parameter, CultureInfo culture) =>
    value != null && value == ((ViewCell)parameter).View.BindingContext;

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

We connect the two using this converter:

<ListView x:Name="ListViewName">
  <ListView.ItemTemplate>
    <DataTemplate>
      <local:SelectableCell x:Name="ListViewCell"
        IsSelected="{Binding SelectedItem, Source={x:Reference ListViewName}, Converter={StaticResource IsSelectedConverter}, ConverterParameter={x:Reference ListViewCell}}" />
    </DataTemplate>
  </ListView.ItemTemplate>
</ListView>

This relatively complex binding serves to check which actual item is currently selected. It compares the SelectedItem property of the list view to the BindingContext of the view in the cell. That binding context is the data object we actually bind to. In other words, it checks whether the data object pointed to by SelectedItem is actually the data object in the cell. If they are the same, we have the selected cell. We bind this into to the IsSelected property which can then be used in XAML or code behind to see if the view cell is in the selected state.

There is just one caveat: if you want to set a default selected item when your page displays, you need to be a bit clever. Unfortunately, Xamarin Forms has no page Displayed event, we only have Appearing and this is too early for setting the default: the binding won't be executed then. So, use a little delay:

protected override async void OnAppearing() {
  base.OnAppearing();

  Device.BeginInvokeOnMainThread(async () => {
    await Task.Delay(100);
    ListViewName.SelectedItem = ...;
  });
}

Yet, it is possible to fake it using a dedicated table, named for your fake-sp, with an AFTER INSERT trigger. The dedicated table rows contain the parameters for your fake sp, and if it needs to return results you can have a second (poss. temp) table (with name related to the fake-sp) to contain those results. It would require two queries: first to INSERT data into the fake-sp-trigger-table, and the second to SELECT from the fake-sp-results-table, which could be empty, or have a message-field if something went wrong.

Check the answer how to implement headers with StoryBoard: Table Header Views in StoryBoards

Also notice that if you don't implement

viewForHeaderInSection:(NSInteger)section

it will not float which is exactly what you want.

You probably don't have the six Python module installed. You can find it on pypi.

To install it:

$ easy_install six

(if you have pip installed, use pip install six instead)

echo $STRING | cut -d " " -f $N

When user press F5 although new request goes to web server and get a responce for the request as well. But when the responce header is Parsed it check the required information in browser cache. If the required information in cache has not expired then that information is restored from in cache itself.

When user click on CTRL-F5 even then new request goes to web server and get a responce. But this time when the responce header is Parsed it do not check any required information in cache, and bring all updated information form server only.

I know the question is about trailing slashes but I found this post during my search for trimming slashes (both at the tail and head of a string literal), as people would need this solution I am posting one here :

'///I am free///'.replace(/^\/+|\/+$/g, ''); // returns 'I am free'

UPDATE:

as @Stephen R mentioned in the comments, if you want to remove both slashes and backslashes both at the tail and the head of a string literal, you would write :

'\/\\/\/I am free\\///\\\\'.replace(/^[\\/]+|[\\/]+$/g, '') // returns 'I am free'

def create_key(key_len):
    key = ''
    valid_characters_list = string.letters + string.digits
    for i in range(key_len):
        character = choice(valid_characters_list)
        key = key + character
    return key

def create_key_list(key_num):
    keys = []
    for i in range(key_num):
        key = create_key(key_len)
        if key not in keys:
            keys.append(key)
    return keys

I ran into this and while I had the og:image (and others), I was missing og:url and og:type, so I added those and then it worked.

<meta property="og:url" content="<? 
 $url = 'https://' . $_SERVER['HTTP_HOST'].$_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING'];; 
echo htmlentities($url,ENT_QUOTES); ?>"/> 

There are many freewares to examine the certificates and key stores such as KeyStore Explorer.

Unzip the apk and open the META-INF/?.RSA file. ? shall be CERT or ANDROID or may be something else. It will display all the information associated with your apk.

Your Code is:

FROM
 dbo.Employees
TO
 exe.Employees

I tried with this query.

ALTER SCHEMA exe TRANSFER dbo.Employees

Just write create schema exe and execute it

git status #then file which you need to push git add example.FileExtension

git commit "message is example"

git push -u origin(or whatever name you used) master(or name of some branch where you want to push it)

I suggest using a directive on a link.

But its not perfect yet. Watch out for the hashbangs ;)

Here is the javascript for directive:

angular.module('link', []).
  directive('activeLink', ['$location', function (location) {
    return {
      restrict: 'A',
      link: function(scope, element, attrs, controller) {
        var clazz = attrs.activeLink;
        var path = attrs.href;
        path = path.substring(1); //hack because path does not return including hashbang
        scope.location = location;
        scope.$watch('location.path()', function (newPath) {
          if (path === newPath) {
            element.addClass(clazz);
          } else {
            element.removeClass(clazz);
          }
        });
      }
    };
  }]);

and here is how it would be used in html:

<div ng-app="link">
  <a href="#/one" active-link="active">One</a>
  <a href="#/two" active-link="active">One</a>
  <a href="#" active-link="active">home</a>
</div>

afterwards styling with css:

.active { color: red; }

After ~7 year, I will update it to better approach which is suggested by Bozho.

File theDir = new File("/path/directory");
if (!theDir.exists()){
    theDir.mkdirs();
}

You need to store the psftp script (lines from open to bye) into a separate file and pass that to psftp using -b switch:

cd "C:\Program Files (x86)\PuTTY"
psftp -b "C:\path\to\script\script.txt"

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-option-b

EDIT: For username+password: As you cannot use psftp commands in a batch file, for the same reason, you cannot specify the username and the password as psftp commands. These are inputs to the open command. While you can specify the username with the open command (open <user>@<IP>), you cannot specify the password this way. This can be done on a psftp command line only. Then it's probably cleaner to do all on the command-line:

cd "C:\Program Files (x86)\PuTTY"
psftp -b script.txt <user>@<IP> -pw <PW>

And remove the open, <user> and <PW> lines from your script.txt.

Reference:
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter6.html#psftp-starting
https://the.earth.li/~sgtatham/putty/latest/htmldoc/Chapter3.html#using-cmdline-pw

What you are doing atm is that you run psftp without any parameter or commands. Once you exit it (like by typing bye), your batch file continues trying to run open command (and others), what Windows shell obviously does not understand.

If you really want to keep everything in one file (the batch file), you can write commands to psftp standard input, like:

(
    echo cd ...
    echo lcd ...
    echo put log.sh
) | psftp -b script.txt <user>@<IP> -pw <PW>

In Python 2.6+, you could use io.open() that is default (builtin open()) on Python 3:

import io

with io.open(filename, 'w', encoding=character_encoding) as file:
    file.write(unicode_text)

It might be more convenient if you need to write the text incrementally (you don't need to call unicode_text.encode(character_encoding) multiple times). Unlike codecs module, io module has a proper universal newlines support.

IT IS NOT IMPOSSIBLE.
Use a reverse proxy server to handle the Different-Origin-Problem. I used to using Nginx with proxy_pass to change the url of page. you can have a try.

Another way is to write a simple proxy page runs on server by yourself, just request from Google and output the result to the client.

SSSSSS is microseconds. Let us say the time is 10:30:22 (Seconds 22) and 10:30:22.1 would be 22 seconds and 1/10 of a second . Extending the same logic , 10:32.22.000132 would be 22 seconds and 132/1,000,000 of a second, which is nothing but microseconds.

How not to do it:

When building an image, you could also tag it this way.

docker build -t ubuntu:14.04 .

Then you build it again with another tag:

docker build -t ubuntu:latest .

If your Dockerfile makes good use of the cache, the same image should come out, and it effectively does the same as retagging the same image. If you do docker images then you will see that they have the same ID.

There's probably a case where this goes wrong though... But like @david-braun said, you can't create tags with Dockerfiles themselves, just with the docker command.

You can do that with simple test command.

$ test ab -eq 1 >/dev/null 2>&1
$ echo $?
2

$ test 21 -eq 1 >/dev/null 2>&1
$ echo $?
1

$ test 1 -eq 1 >/dev/null 2>&1
$ echo $?
0

So if the exit status is either 0 or 1 then it is a integer , but if the exis status is 2 then it is not a number.

In addition to the answer of BalusC, use the following Java RegExp to replace && with and:

Search:  (#\{[^\}]*)(&&)([^\}]*\})
Replace: $1and$3

You have run this regular expression replacement multiple times to find all occurences in case you are using >2 literals in your EL expressions. Mind to replace the leading # by $ if your EL expression syntax differs.

One of the benefits is that Razor views can be rendered inside unit tests, this is something that was not easily possible with the previous ASP.Net renderer.

From ScottGu's announcement this is listed as one of the design goals:

Unit Testable: The new view engine implementation will support the ability to unit test views (without requiring a controller or web-server, and can be hosted in any unit test project – no special app-domain required).

<form action="" method="get">
   <input type="text" name="search" required="required" placeholder="type here" />
   <input type="reset" value="" alt="clear" />
</form>

<style>
   input[type="text"]
   {
      height: 38px;
      font-size: 15pt;
   }

   input[type="text"]:invalid + input[type="reset"]{
     display: none;
   } 

   input[type="reset"]
   {
      background-image: url( http://png-5.findicons.com/files/icons/1150/tango/32/edit_clear.png );
      background-position: center center;
      background-repeat: no-repeat;
      height: 38px;
      width: 38px;
      border: none;
      background-color: transparent;
      cursor: pointer;
      position: relative;
      top: -9px;
      left: -44px;
   }
</style>

"Only conventions? Or is there more behind the underscore prefix?"

Apart from privacy conventions, I also wanted to help bring awareness that the underscore prefix is also used for arguments that are dependent on independent arguments, specifically in URI anchor maps. Dependent keys always point to a map.

Example ( from https://github.com/mmikowski/urianchor ) :

$.uriAnchor.setAnchor({
  page   : 'profile',
  _page  : {
    uname   : 'wendy',
    online  : 'today'
  }
});

The URI anchor on the browser search field is changed to:

\#!page=profile:uname,wendy|online,today

This is a convention used to drive an application state based on hash changes.

I had this problem when I added Swift source code to an existing ObjC static framework (dynamic framework with Mach-O type "Static Library").

The fix was setting CLANG_ENABLE_MODULES ("Enable Modules" in build settings) to YES

Response.Write("<script> try {this.submit();} catch(e){} </script>");

I dug myself into a slight variant on this problem by mistakenly running the setfacl command. I ran:

sudo setfacl -m user:nginx:r /home/foo/bar

I abandoned this route in favor of adding nginx to the foo group, but that custom ACL was foiling nginx's attempts to access the file. I cleared it by running:

sudo setfacl -b /home/foo/bar

And then nginx was able to access the files.

One thing to keep in mind with positioning is that each view has an index relative to its parent view. So if you have a linear layout with three subviews, the subviews will each have an index: 0, 1, 2 in the above case.

This allows you to add a view to the last position (or the end) in a parent view by doing something like this:

int childCount = parent.getChildCount();
parentView.addView(newView, childCount);

Alternatively you could replace a view using something like the following:

int childIndex = parentView.indexOfChild(childView);
childView.setVisibility(View.GONE);

parentView.addView(newView, childIndex);

My experience is that Ionic Pro (https://ionicframework.com/pro) can do the most of the Development and Publish job but you still need Mac or Mac in cloud at these steps:

• create .p12 Certification file
• upload the .ipa file to the App Store

After you created your Certification file, You can upload it to Ionic Pro. You can build .ipa files with proper credentials in cloud. But unfortunately I didn't found another way to upload the .ipa file to App Store, only with Application Loader from Mac.

So I decided to use a pay-as-you-go Mac in cloud account (you pay only for minutes you are logged in) since the time I spend on Mac is very limited (few minutes per App publication).

Only the Assets and ProjectSettings folders need to be under git version control.

You can make a gitignore like this.

[Ll]ibrary/
[Tt]emp/
[Oo]bj/

# Autogenerated VS/MD solution and project files
*.csproj
*.unityproj
*.sln
*.suo
*.userprefs

# Mac
.DS_Store
*.swp
*.swo

Thumbs.db
Thumbs.db.meta

.vs/

the Request.ServerVariables object works for me. I don't know of any reason not to use it.

ServerVariables["SERVER_NAME"] and ServerVariables["HTTP_URL"] should get what you're looking for

JSONArray may be what you want.

String message;
JSONObject json = new JSONObject();
json.put("name", "student");

JSONArray array = new JSONArray();
JSONObject item = new JSONObject();
item.put("information", "test");
item.put("id", 3);
item.put("name", "course1");
array.put(item);

json.put("course", array);

message = json.toString();

// message
// {"course":[{"id":3,"information":"test","name":"course1"}],"name":"student"}

Not to be vague or anything but I think the type of 'file' you will be storing is one of the biggest determining factors. If you essentially talking about a large text field which could be stored as file my preference would be for db storage.

Use @AutoConfigureMockMvc for test class.

You can mix git blame and git log commands to retrieve the summary of each commit in the git blame command and append them. Something like the following bash + awk script. It appends the commit summary as code comment inline.

git blame FILE_NAME | awk -F" " \
'{
   commit = substr($0, 0, 8);
   if (!a[commit]) {
     query = "git log --oneline -n 1 " commit " --";
     (query | getline a[commit]);
   }
   print $0 "  // " substr(a[commit], 9);
 }'

In one line:

git blame FILE_NAME | awk -F" " '{ commit = substr($0, 0, 8); if (!a[commit]) { query = "git log --oneline -n 1 " commit " --"; (query | getline a[commit]); } print $0 "  // " substr(a[commit], 9); }'

merge actually doesn't work like OR. It's simply intersection (AND)

I struggled with this problem to combine to ActiveRecord::Relation objects into one and I didn't found any working solution for me.

Instead of searching for right method creating an union from these two sets, I focused on algebra of sets. You can do it in different way using De Morgan's law

ActiveRecord provides merge method (AND) and also you can use not method or none_of (NOT).

search.where.none_of(search.where.not(id: ids_to_exclude).merge(search.where.not("title ILIKE ?", "%#{query}%")))

You have here (A u B)' = A' ^ B'

UPDATE: The solution above is good for more complex cases. In your case smth like that will be enough:

User.where('first_name LIKE ? OR last_name LIKE ?', 'Tobias', 'Fünke')

What are you going to do with the URI?

If you're just going to use it with an HttpGet for example, you can just use the string directly when creating the HttpGet instance.

HttpGet get = new HttpGet("http://stackoverflow.com");

This should do it:

UPDATE TheTable
SET PhoneNumber = SUBSTRING(PhoneNumber, 1, 3) + '-' + 
                  SUBSTRING(PhoneNumber, 4, 3) + '-' + 
                  SUBSTRING(PhoneNumber, 7, 4)

Incorporated Kane's suggestion, you can compute the phone number's formatting at runtime. One possible approach would be to use scalar functions for this purpose (works in SQL Server):

CREATE FUNCTION FormatPhoneNumber(@phoneNumber VARCHAR(10))
RETURNS VARCHAR(12)
BEGIN
    RETURN SUBSTRING(@phoneNumber, 1, 3) + '-' + 
           SUBSTRING(@phoneNumber, 4, 3) + '-' + 
           SUBSTRING(@phoneNumber, 7, 4)
END

You can set the index by this code :

sel.selectedIndex = 0;

but remember a caution in this practice, You would not be able to call the server side onclick method if you select the previous value selected in the drop down..

#1 form

a = ('x', 'y')
b = a + ('z',)
print(b)

#2 form

a = ('x', 'y')
b = a + tuple('b')
print(b)

As above mentioned, first of all run your git command from bash adding the enhanced log directives in the beginning: GIT_TRACE=1 GIT_CURL_VERBOSE=1 git ...

e.g. GIT_CURL_VERBOSE=1 GIT_TRACE=1 git -c diff.mnemonicprefix=false -c core.quotepath=false fetch origin This will show you detailed error information.

I think you can use Padding like: Hope this one can help you.

.loginButton {
    background:url(images/loginBtn-center.jpg) repeat-x;
    width:175px;
    height:65px;
    margin:20px auto;
    border-radius:10px;
    -webkit-border-radius:10px;
    box-shadow:0 1px 2px #5e5d5b;
    <!--Using padding to align text in box or image-->
    padding: 3px 2px;
}

to get the WSDL (Web Service Description Language) from a Web Service URL.

Is possible from SOAP Web Services:

http://www.w3schools.com/xml/tempconvert.asmx

to get the WSDL we have only to add ?WSDL , for example:

http://www.w3schools.com/xml/tempconvert.asmx?WSDL

A bit late, but you can easily find a string with this query

DECLARE
@search_string  VARCHAR(100),
@table_name     SYSNAME,
@table_id       INT,
@column_name    SYSNAME,
@sql_string     VARCHAR(2000)

SET @search_string = 'StringtoSearch'

DECLARE tables_cur CURSOR FOR SELECT ss.name +'.'+ so.name [name], object_id FROM sys.objects so INNER JOIN sys.schemas ss ON so.schema_id = ss.schema_id WHERE  type = 'U'

OPEN tables_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id

WHILE (@@FETCH_STATUS = 0)
BEGIN
    DECLARE columns_cur CURSOR FOR SELECT name FROM sys.columns WHERE object_id = @table_id 
        AND system_type_id IN (167, 175, 231, 239)

    OPEN columns_cur

    FETCH NEXT FROM columns_cur INTO @column_name
        WHILE (@@FETCH_STATUS = 0)
        BEGIN
            SET @sql_string = 'IF EXISTS (SELECT * FROM ' + @table_name + ' WHERE [' + @column_name + '] 
            LIKE ''%' + @search_string + '%'') PRINT ''' + @table_name + ', ' + @column_name + ''''

            EXECUTE(@sql_string)

        FETCH NEXT FROM columns_cur INTO @column_name
        END

    CLOSE columns_cur

DEALLOCATE columns_cur

FETCH NEXT FROM tables_cur INTO @table_name, @table_id
END

CLOSE tables_cur
DEALLOCATE tables_cur

You have not appended your li as a child to your ul element

Try this

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Four"));
  ul.appendChild(li);
}

If you need to set the id , you can do so by

li.setAttribute("id", "element4");

Which turns the function into

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Four"));
  li.setAttribute("id", "element4"); // added line
  ul.appendChild(li);
  alert(li.id);
}

The following query works. It uses each group to do the select instead of SelectMany. SelectMany works on each element from each collection. For example, in your query you have a result of 2 collections. SelectMany gets all the results, a total of 3, instead of each collection. The following code works on each IGrouping in the select portion to get your aggregate operations working correctly.

var results = from line in Lines
              group line by line.ProductCode into g
              select new ResultLine {
                ProductName = g.First().Name,
                Price = g.Sum(pc => pc.Price).ToString(),
                Quantity = g.Count().ToString(),
              };

I have no problem with any of the existing answers, but I was surprised to not find this solution:

keys_to_remove = ['a', 'b', 'c']
my_dict = {k: v for k, v in zip("a b c d e f g".split(' '), [0, 1, 2, 3, 4, 5, 6])}

for k in keys_to_remove:
    try:
        del my_dict[k]
    except KeyError:
        pass

assert my_dict == {'d': 3, 'e': 4, 'f': 5, 'g': 6}

Note: I stumbled across this question coming from here. And my answer is related to this answer.

You can try to add some time.sleep calls to your code.

It seems like the server side limits the amount of requests per timeunit (hour, day, second) as a security issue. You need to guess how many (maybe using another script with a counter?) and adjust your script to not surpass this limit.

In order to avoid your code from crashing, try to catch this error with try .. except around the urllib2 calls.

Since python 3.4 pip is included in the installation of python.

Your question is similar to below:

What is the difference between application server and web server?

In Java: Web Container or Servlet Container or Servlet Engine : is used to manage the components like Servlets, JSP. It is a part of the web server.

Web Server or HTTP Server: A server which is capable of handling HTTP requests, sent by a client and respond back with a HTTP response.

Application Server or App Server: can handle all application operations between users and an organization's back end business applications or databases.It is frequently viewed as part of a three-tier application with: Presentation tier, logic tier,Data tier

Start to look at the execution plans to see the differences in how the SQl Server will interpret them. You can also use Profiler to actually run the queries multiple times and get the differnce.

I would not expect these to be so horribly different, where you can get get real, large performance gains in using joins instead of subqueries is when you use correlated subqueries.

EXISTS is often better than either of these two and when you are talking left joins where you want to all records not in the left join table, then NOT EXISTS is often a much better choice.

Update for python 3.0 and later. Try the following in the python editor:

locale-gen en_US.UTF-8
export LANG=en_US.UTF-8 LANGUAGE=en_US.en
LC_ALL=en_US.UTF-8

This sets the system`s default locale encoding to the UTF-8 format.

More can be read here at PEP 538 -- Coercing the legacy C locale to a UTF-8 based locale.

Why don't you try the fadeIn() instead of using a show() with delay(). I think what you are trying to do can be done with this. Here is the jQuery code for fadeIn and FadeOut() which also has inbuilt method for delaying the process.

$(document).ready(function(){
   $('element').click(function(){
      //effects take place in 3000ms
      $('element_to_hide').fadeOut(3000);
      $('element_to_show').fadeIn(3000);
   });
}

From R 3.0.0 onwards mean(<data.frame>) is defunct (and passing a data.frame to mean will give the error you state)

A data frame is a list of variables of the same number of rows with unique row names, given class "data.frame".

In your case, result has two variables (if your description is correct) . You could obtain the column means by using any of the following

lapply(results, mean, na.rm = TRUE)
sapply(results, mean, na.rm = TRUE)
colMeans(results, na.rm = TRUE)

An old tip...

var daddy = window.self;
daddy.opener = window.self;
daddy.close();

You cannot change the color of colorPrimary, but you can change the theme of your application by adding a new style with a different colorPrimary color

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
</style>

<style name="AppTheme.NewTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorOne</item>
    <item name="colorPrimaryDark">@color/colorOneDark</item>
</style>

and inside the activity set theme

 setTheme(R.style.AppTheme_NewTheme);
 setContentView(R.layout.activity_main);

It worked for me when HDD with win8.1 crashed and my new HDD has win10. Important to know - Create Legacy folder mentioned in this link. - Remember to rename the StickyNotes.snt to ThresholdNotes.snt. - Restart the app

I guess the answer you need is referenced here Python sets are not json serializable

Not all datatypes can be json serialized . I guess pickle module will serve your purpose.

If you are building your project with gradle, you just need to add one line to the dependencies in the build.gradle:

buildscript {
    ...
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])

and then add the folder to your root project or module:

Then you drop your jars in there and you are good to go :-)

I prefer to use BINARY(32) since it's the optimized way!

You can place in that 32 hex digits from (00 to FF).

Therefore BINARY(32)!

event.key === "Delete"

More recent and much cleaner: use event.key. No more arbitrary number codes!

NOTE: The old properties (.keyCode and .which) are Deprecated.

document.addEventListener('keydown', function(event) {
    const key = event.key; // const {key} = event; ES6+
    if (key === "Delete") {
        // Do things
    }
});

You can now achieve the result in just one line of code.

Using new Set to reduce the array to unique set of values. Apply the sort method after to order the string values.

var myData=['237','124','255','124','366','255']

var uniqueAndSorted = [...new Set(myData)].sort() 

UPDATED for newer methods introduced in JavaScript since time of question.

You can use yahoo's symbol lookup like so:

http://d.yimg.com/autoc.finance.yahoo.com/autoc?query=yahoo&callback=YAHOO.Finance.SymbolSuggest.ssCallback

Where query is the company name.

You'll get something like this in return:

YAHOO.Finance.SymbolSuggest.ssCallback(

Which is JSON and very easy to work with.

Hush... don't tell anybody.

You need to destroy:

myLineChart.destroy();

Then re-initialize the chart:

var ctx = document.getElementById("myChartLine").getContext("2d");
myLineChart = new Chart(ctx).Line(data, options);

Heres a solution with no Javascript or plugin - just some css and one extra class in the markup. This solutions uses the fact that BootStrap adds a class to the body when a dialog is open. We use this class to then hide the body, and print only the dialog.

To ensure we can determine the main body of the page we need to contain everything within the main page content in a div - I've used id="mainContent". Sample Page layout below - with a main page and two dialogs

<body>
 <div class="container body-content">

  <div id="mainContent">
       main page stuff     
  </div>
  <!-- Dialog One -->
  <div class="modal fade in">
   <div class="modal-dialog">
    <div class="modal-content">
          ...
    </div>
   </div>
  </div>

  <!-- Dialog Two -->
  <div class="modal fade in">
   <div class="modal-dialog">
    <div class="modal-content">
          ...
    </div>
   </div>
  </div>

 </div>
</body>

Then in our CSS print media queries, I use display: none to hide everything I don't want displayed - ie the mainContent when a dialog is open. I also use a specific class noPrint to be used on any parts of the page that should not be displayed - say action buttons. Here I am also hiding the headers and footers. You may need to tweak it to get exactly want you want.

@media print {
    header, .footer, footer {
        display: none;
    }

    /* hide main content when dialog open */
    body.modal-open div.container.body-content div#mainContent {
        display: none;
    }

    .noPrint {
        display: none;
    }
}

I have custom loading. Properties must be defined as:

key.0=value0
key.1=value1
...

Custom loading:

/** Return array from properties file. Array must be defined as "key.0=value0", "key.1=value1", ... */
public List<String> getSystemStringProperties(String key) {

    // result list
    List<String> result = new LinkedList<>();

    // defining variable for assignment in loop condition part
    String value;

    // next value loading defined in condition part
    for(int i = 0; (value = YOUR_PROPERTY_OBJECT.getProperty(key + "." + i)) != null; i++) {
        result.add(value);
    }

    // return
    return result;
}

If you are planning to use appending more then once, you might want to write a function:

//Append text to input element
function jQ_append(id_of_input, text){
    var input_id = '#'+id_of_input;
    $(input_id).val($(input_id).val() + text);
}

After you can just call it:

jQ_append('my_input_id', 'add this text');

It's the null coalescing operator, and quite like the ternary (immediate-if) operator. See also ?? Operator - MSDN.

FormsAuth = formsAuth ?? new FormsAuthenticationWrapper();

expands to:

FormsAuth = formsAuth != null ? formsAuth : new FormsAuthenticationWrapper();

which further expands to:

if(formsAuth != null)
    FormsAuth = formsAuth;
else
    FormsAuth = new FormsAuthenticationWrapper();

In English, it means "If whatever is to the left is not null, use that, otherwise use what's to the right."

Note that you can use any number of these in sequence. The following statement will assign the first non-null Answer# to Answer (if all Answers are null then the Answer is null):

string Answer = Answer1 ?? Answer2 ?? Answer3 ?? Answer4;

Also it's worth mentioning while the expansion above is conceptually equivalent, the result of each expression is only evaluated once. This is important if for example an expression is a method call with side effects. (Credit to @Joey for pointing this out.)

Use a concrete list type, e.g. ArrayList instead of just List.

I encountered the following message repeatedly when trying to start SQL Developer from my installation of Oracle Database 11g Enterprise: Enter the full pathname for java.exe.

No matter how many times I browsed to the correct path, I kept being presented with the exact same dialog box. This was in Windows 7, and the solution was to right-click on the SQL Developer icon and select "Run as administrator". I then used this path: C:\app\shellperson\product\11.1.0\db_1\jdk\jre\bin\java.exe

Here is a basic hover example.

Component's template property:

Template

<!-- attention, we have the c_highlight class -->
<!-- c_highlight is the selector property value of the directive -->

<p class="c_highlight">
    Some text.
</p>

And our directive

import {Component,HostListener,Directive,HostBinding} from '@angular/core';

@Directive({
    // this directive will work only if the DOM el has the c_highlight class
    selector: '.c_highlight'
 })
export class HostDirective {

  // we could pass lots of thing to the HostBinding function. 
  // like class.valid or attr.required etc.

  @HostBinding('style.backgroundColor') c_colorrr = "red"; 

  @HostListener('mouseenter') c_onEnterrr() {
   this.c_colorrr= "blue" ;
  }

  @HostListener('mouseleave') c_onLeaveee() {
   this.c_colorrr = "yellow" ;
  } 
}

That should do the trick for the newest MySQL versions:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE DB = "elstream_development";

You can do this in Spring 3 using EL support. Example:

@Value("#{systemProperties.databaseName}")
public void setDatabaseName(String dbName) { ... }

@Value("#{strategyBean.databaseKeyGenerator}")
public void setKeyGenerator(KeyGenerator kg) { ... }

systemProperties is an implicit object and strategyBean is a bean name.

One more example, which works when you want to grab a property from a Properties object. It also shows that you can apply @Value to fields:

@Value("#{myProperties['github.oauth.clientId']}")
private String githubOauthClientId;

Here is a blog post I wrote about this for a little more info.

I am working on Windows And I have tried lots of things provided here as answer but Pop up was disabling the extension continually then i have tried following steps and it works now:

1. Go to chrome://extensions page and click Pack extension button and select your root Directory of extension by clicking on red rectangled browse button displayed in below image.

2. after selecting root directory Click on Pack extension button displayed in red circle in below image.

3. Now in check parent directory of your selected root directory of extension, 2 file would have created [extension name].crx and [extension name].pem.

4. Now just drag and drop the [extension name].crx file onto the chrome://extensions page and it will ask using add app dialog box click on Add app and refresh the page it is installed now.

Note: Before doing anything as above make sure to enable Developer mode for extensions. If this was not enabled, refresh the chrome://extensions page after enabling it.

You could use DATE_ADD : (or ADDDATE with INTERVAL)

UPDATE table SET date = DATE_ADD(date, INTERVAL 1 YEAR) 

I think you are saying that you have python2 and python3 installed and have added a reference to each version under Pycharm > Settings > Project Interpreter

What I think you are asking is how do you have some projects run with Python 2 and some projects running with Python 3.

If so, you can look under Run > Edit Configurations

Sometimes you want to delete a file whatever the case(whatever the exception occurs ,please do delete the file). For such situations.

public static void DeleteFile(string path)
        {
            if (!File.Exists(path))
            {
                return;
            }

            bool isDeleted = false;
            while (!isDeleted)
            {
                try
                {
                    File.Delete(path);
                    isDeleted = true;
                }
                catch (Exception e)
                {
                }
                Thread.Sleep(50);
            }
        }

Note:An exception is not thrown if the specified file does not exist.

This occurs when you specify the different name for repository table name and database table name. Please check your table name with database and repository.

A little late to the party, but NodeJS (as of ~Nov 14 I guess) supports corporate NPM repositories - you can find out more on their official site.

From a cursory glance it would appear that npmE allows fall-through mirroring of the NPM repository - that is, it will look up packages in the real NPM repository if it can't find one on your internal one. Seems very useful!

npm Enterprise is an on-premises solution for securely sharing and distributing JavaScript modules within your organization, from the team that maintains npm and the public npm registry. It's designed for teams that need:

easy internal sharing of private modules better control of development and deployment workflow stricter security around deploying open-source modules compliance with legal requirements to host code on-premises npmE is private npm

npmE is an npm registry that works with the same standard npm client you already use, but provides the features needed by larger organizations who are now enthusiastically adopting node. It's built by npm, Inc., the sponsor of the npm open source project and the host of the public npm registry.

Unfortunately, it's not free. You can get a trial, but it is commerical software. This is the not so great bit for solo developers, but if you're a solo developer, you have GitHub :-)

The usual way is to use String#getBytes() to get the underlying bytes and then present those bytes in some other form (hex, binary whatever).

Note that getBytes() uses the default charset, so if you want the string converted to some specific character encoding, you should use getBytes(String encoding) instead, but many times (esp when dealing with ASCII) getBytes() is enough (and has the advantage of not throwing a checked exception).

For specific conversion to binary, here is an example:

  String s = "foo";
  byte[] bytes = s.getBytes();
  StringBuilder binary = new StringBuilder();
  for (byte b : bytes)
  {
     int val = b;
     for (int i = 0; i < 8; i++)
     {
        binary.append((val & 128) == 0 ? 0 : 1);
        val <<= 1;
     }
     binary.append(' ');
  }
  System.out.println("'" + s + "' to binary: " + binary);

Running this example will yield:

'foo' to binary: 01100110 01101111 01101111 

Delete your "body background image code" then paste this code:

html { 
    background: url(../img/background.jpg) no-repeat center center fixed #000; 
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
}

Cconvert NSTimeInterval milisecondedDate value to nsstring and after that convert into int.

I wanted to elevate this answer out of a comment section because it's one of the most elegant solutions in the thread. Full credit for this answer goes to @joeb.

pip uninstall -y -r <(pip freeze)

This worked great for me for the use case of clearing my user packages folder outside the context of a virtualenv which many of the above answers don't handle.

Edit: Anyone know how to make this command work in a Makefile?

Bonus: A bash alias

I add this to my bash profile for convenience:

alias pipuninstallall="pip uninstall -y -r <(pip freeze)"

Then run:

pipuninstallall

Alternative for pipenv

If you happen to be using pipenv you can just run:

pipenv uninstall --all

Only uninstalling (sudo apt-get purge) libpq-dev and re-installing it worked for me.

Here's what I ended up with. It's a listing of all properties and methods, and I listed all parameters for each method. I didn't succeed on getting all of the values.

foreach(System.Reflection.AssemblyName an in System.Reflection.Assembly.GetExecutingAssembly().GetReferencedAssemblies()){                      
            System.Reflection.Assembly asm = System.Reflection.Assembly.Load(an.ToString());
            foreach(Type type in asm.GetTypes()){   
                //PROPERTIES
                foreach (System.Reflection.PropertyInfo property in type.GetProperties()){
                    if (property.CanRead){
                        Response.Write("<br>" + an.ToString() + "." + type.ToString() + "." + property.Name);       
                    }
                }
                //METHODS
                var methods = type.GetMethods();
                foreach (System.Reflection.MethodInfo method in methods){               
                    Response.Write("<br><b>" + an.ToString() + "."  + type.ToString() + "." + method.Name  + "</b>");   
                    foreach (System.Reflection.ParameterInfo param in method.GetParameters())
                    {
                        Response.Write("<br><i>Param=" + param.Name.ToString());
                        Response.Write("<br>  Type=" + param.ParameterType.ToString());
                        Response.Write("<br>  Position=" + param.Position.ToString());
                        Response.Write("<br>  Optional=" + param.IsOptional.ToString() + "</i>");
                    }
                }
            }
        }

Here are my personal, super-condensed notes, as far as this subject pertains to me currently, for anyone who's interested:

• Both PKCS12 and PEM can store entire cert chains: public keys, private keys, and root (CA) certs.
• .pfx == .p12 == "PKCS12"
  • fully encrypted
• .pem == .cer == .cert == "PEM" (or maybe not... could be binary... see comments...)
  • base-64 (string) encoded X509 cert (binary) with a header and footer
    • base-64 is basically just a string of "A-Za-z0-9+/" used to represent 0-63, 6 bits of binary at a time, in sequence, sometimes with 1 or 2 "=" characters at the very end when there are leftovers ("=" being "filler/junk/ignore/throw away" characters)
    • the header and footer is something like "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----" or "-----BEGIN ENCRYPTED PRIVATE KEY-----" and "-----END ENCRYPTED PRIVATE KEY-----"
  • Windows recognizes .cer and .cert as cert files
• .jks == "Java Key Store"
  • just a Java-specific file format which the API uses
    • .p12 and .pfx files can also be used with the JKS API
• "Trust Stores" contain public, trusted, root (CA) certs, whereas "Identity/Key Stores" contain private, identity certs; file-wise, however, they are the same.

I'd just like to add a general note of caution.

If all you are doing is getting the current time from the computer's internal clock to put a date/time on the display or a report, then all is well. But if you are saving the date/time information for later reference or are computing date/times, beware!

Let's say you determine that a cruise ship arrived in Honolulu on 20 Dec 2007 at 15:00 UTC. And you want to know what local time that was.
1. There are probably at least three 'locals' involved. Local may mean Honolulu, or it may mean where your computer is located, or it may mean the location where your customer is located.
2. If you use the built-in functions to do the conversion, it will probably be wrong. This is because daylight savings time is (probably) currently in effect on your computer, but was NOT in effect in December. But Windows does not know this... all it has is one flag to determine if daylight savings time is currently in effect. And if it is currently in effect, then it will happily add an hour even to a date in December.
3. Daylight savings time is implemented differently (or not at all) in various political subdivisions. Don't think that just because your country changes on a specific date, that other countries will too.

You can use ElementRef as shown below,

DEMO : https://plnkr.co/edit/XZwXEh9PZEEVJpe0BlYq?p=preview check browser's console.

import { Directive,Input,Outpu,ElementRef,Renderer} from '@angular/core';

@Directive({
  selector:"[move]",
  host:{
    '(click)':"show()"
  }
})

export class GetEleDirective{

  constructor(private el:ElementRef){

  }
  show(){
    console.log(this.el.nativeElement);

    console.log('height---' + this.el.nativeElement.offsetHeight);  //<<<===here
    console.log('width---' + this.el.nativeElement.offsetWidth);    //<<<===here
  }
}

Same way you can use it within component itself wherever you need it.

In Java 7+ you can do this in static method/fields:

MethodHandles.lookup().lookupClass()

I had a problem to read/parse the object from S3 because of .get() using Python 2.7 inside an AWS Lambda.

I added json to the example to show it became parsable :)

import boto3
import json

s3 = boto3.client('s3')

obj = s3.get_object(Bucket=bucket, Key=key)
j = json.loads(obj['Body'].read())

NOTE (for python 2.7): My object is all ascii, so I don't need .decode('utf-8')

NOTE (for python 3.6+): We moved to python 3.6 and discovered that read() now returns bytes so if you want to get a string out of it, you must use:

j = json.loads(obj['Body'].read().decode('utf-8'))

another example following @jake stayman:

{% for key, item in row.divs %}
    {% if (key not in [1,2,9]) %} // eliminate element 1,2,9
        <li>{{ item }}</li>
    {% endif %}
{% endfor %}

Use this code in any fragment button listener:

InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(getActivity().INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getActivity().getCurrentFocus().getWindowToken(), 0);

Add

android:screenOrientation="portrait" 

or

 android:screenOrientation="landscape" 

to the <activity> element/s in the manifest and you're done.

ALTERNATIVE FOR LINE-BY-LINE SCROLLING

Ctrl + Shift + Up Arrow or Down Arrow

Unlike Shift + Page Up or Page Down, which scrolls the entire page, this will help with a smoother line-by-line scrolling, which is exactly what I was looking for.

When making an Android app in eclipse, just right-click on the res folder, click New -> Other, and select Android Icon Set under Android.

This allows you to make more icons (or replace any existing ones) easily.

One way to solve is to give a static factory method to allocate the array if for some reason you want to give constructor private.

static Car*  Car::CreateCarArray(int dimensions)

But why are you keeping one constructor public and other private?

But anyhow one more way is to declare the public constructor with default value

#define DEFAULT_CAR_INIT 0
Car::Car(int _no=DEFAULT_CAR_INIT);

Since you tagged it Rails, you can use truncate:

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-truncate

Example:

 truncate(@text, :length => 17)

Excerpt is nice to know too, it lets you display an excerpt of a text Like so:

 excerpt('This is an example', 'an', :radius => 5)
 # => ...s is an exam...

http://api.rubyonrails.org/classes/ActionView/Helpers/TextHelper.html#method-i-excerpt

I was facing the same issue and the reason was single backslah. I used double backslash in my "Data source" and it worked

connetionString = "Data Source=localhost\\SQLEXPRESS;Database=databasename;Integrated Security=SSPI";

From http://docs.python.org/tutorial/datastructures.html:

"The keys() method of a dictionary object returns a list of all the keys used in the dictionary, in arbitrary order (if you want it sorted, just apply the sorted() function to it)."

At work here we use Dotfuscator from PreEmptive Solutions.

Although it's impossible to protect .NET assemblies 100% Dotfuscator makes it hard enough I think. I comes with a lot of obfuscation techniques;

There are freeware alternatives of course;

Here you can find the direct download link for Curl.exe

I was looking for the download process of Curl and every where they said copy curl.exe file in System32 but they haven't provided the direct link but after digging little more I Got it. so here it is enjoy, find curl.exe easily in bin folder just

unzip it and then go to bin folder there you get exe file

link to download curl generic

simple load xml file ..

$xml = @simplexml_load_string($retValuet);

$status = (string)$xml->Status; 
$operator_trans_id = (string)$xml->OPID;
$trns_id = (string)$xml->TID;

?>

other alternative is using math operation by dividing it, for example:

switch ((int) num/10) {
    case 1:
        System.out.println("10-19");
        break;
    case 2:
        System.out.println("20-29");
        break;
    case 3:
        System.out.println("30-39");
        break;
    case 4:
        System.out.println("40-49");
        break;
    default:
        break;
}

But, as you can see this can only be used when the range is fixed in each case.

This might look stupid, but check if you haven't already added the folder/files you are trying to ignore to the index before. If you did, it does not matter what you put in your .gitignore file, the folders/files will still be staged.

For Python3

Step 1: Install Dependencies

sudo apt-get install python3 python-dev python3-dev

Step 2: Install

pip install psycopg2

To fix this you can simply use the exclamation mark if you're sure that the object is not null when accessing its property:

list!.values

At first sight, some people might confuse this with the safe navigation operator from angular, this is not the case!

list?.values

The ! post-fix expression will tell the TS compiler that variable is not null, if that's not the case it will crash at runtime

useRef

for useRef hook use like this

const value = inputRef?.current?.value

from PIL import Image

background = Image.open("test1.png")
foreground = Image.open("test2.png")

background.paste(foreground, (0, 0), foreground)
background.show()

First parameter to .paste() is the image to paste. Second are coordinates, and the secret sauce is the third parameter. It indicates a mask that will be used to paste the image. If you pass a image with transparency, then the alpha channel is used as mask.

Check the docs.

Java:

public static boolean isValidEmail(CharSequence target) {
    return (!TextUtils.isEmpty(target) && Patterns.EMAIL_ADDRESS.matcher(target).matches());
}

Kotlin:

fun CharSequence?.isValidEmail() = !isNullOrEmpty() && Patterns.EMAIL_ADDRESS.matcher(this).matches()

Edit: It will work On Android 2.2+ onwards !!

Edit: Added missing ;

Calendar start = Calendar.getInstance();
Calendar end = Calendar.getInstance();
start.set(2010, 7, 23);
end.set(2010, 8, 26);
Date startDate = start.getTime();
Date endDate = end.getTime();
long startTime = startDate.getTime();
long endTime = endDate.getTime();
long diffTime = endTime - startTime;
long diffDays = diffTime / (1000 * 60 * 60 * 24);
DateFormat dateFormat = DateFormat.getDateInstance();
System.out.println("The difference between "+
  dateFormat.format(startDate)+" and "+
  dateFormat.format(endDate)+" is "+
  diffDays+" days.");

This will not work when crossing daylight savings time (or leap seconds) as orange80 pointed out and might as well not give the expected results when using different times of day. Using JodaTime might be easier for correct results, as the only correct way with plain Java before 8 I know is to use Calendar's add and before/after methods to check and adjust the calculation:

start.add(Calendar.DAY_OF_MONTH, (int)diffDays);
while (start.before(end)) {
    start.add(Calendar.DAY_OF_MONTH, 1);
    diffDays++;
}
while (start.after(end)) {
    start.add(Calendar.DAY_OF_MONTH, -1);
    diffDays--;
}

This query here will list the total size that a table takes up - clustered index, heap and all nonclustered indices:

SELECT 
    s.Name AS SchemaName,
    t.NAME AS TableName,
    p.rows AS RowCounts,
    SUM(a.total_pages) * 8 AS TotalSpaceKB, 
    SUM(a.used_pages) * 8 AS UsedSpaceKB, 
    (SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM 
    sys.tables t
INNER JOIN 
    sys.schemas s ON s.schema_id = t.schema_id
INNER JOIN      
    sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN 
    sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN 
    sys.allocation_units a ON p.partition_id = a.container_id
WHERE 
    t.NAME NOT LIKE 'dt%'    -- filter out system tables for diagramming
    AND t.is_ms_shipped = 0
    AND i.OBJECT_ID > 255 
GROUP BY 
    t.Name, s.Name, p.Rows
ORDER BY 
    s.Name, t.Name

If you want to separate table space from index space, you need to use AND i.index_id IN (0,1) for the table space (index_id = 0 is the heap space, index_id = 1 is the size of the clustered index = data pages) and AND i.index_id > 1 for the index-only space

Well, you can create your own type - but a DateTime always has a full date and time. You can't even have "just a date" using DateTime - the closest you can come is to have a DateTime at midnight.

You could always ignore the year though - or take the current year:

// Consider whether you want DateTime.UtcNow.Year instead
DateTime value = new DateTime(DateTime.Now.Year, month, day);

To create your own type, you could always just embed a DateTime within a struct, and proxy on calls like AddDays etc:

public struct MonthDay : IEquatable<MonthDay>
{
    private readonly DateTime dateTime;

    public MonthDay(int month, int day)
    {
        dateTime = new DateTime(2000, month, day);
    }

    public MonthDay AddDays(int days)
    {
        DateTime added = dateTime.AddDays(days);
        return new MonthDay(added.Month, added.Day);
    }

    // TODO: Implement interfaces, equality etc
}

Note that the year you choose affects the behaviour of the type - should Feb 29th be a valid month/day value or not? It depends on the year...

Personally I don't think I would create a type for this - instead I'd have a method to return "the next time the program should be run".

I am assuming that you are making a quiz kind of application. For this kind of application I have written a function which is as follows:

def shuffle(q):
"""
The input of the function will 
be the dictionary of the question
and answers. The output will
be a random question with answer
"""
selected_keys = []
i = 0
while i < len(q):
    current_selection = random.choice(q.keys())
    if current_selection not in selected_keys:
        selected_keys.append(current_selection)
        i = i+1
        print(current_selection+'? '+str(q[current_selection]))

If I will give the input of questions = {'VENEZUELA':'CARACAS', 'CANADA':'TORONTO'} and call the function shuffle(questions) Then the output will be as follows:

VENEZUELA? CARACAS
CANADA? TORONTO

You can extend this further more by shuffling the options also

Below mentioned link gives the clear explanation with example.

Here is a simpler solution to list all files in a directory and to download it.

In your index.php file

<?php
$dir = "./";

$allFiles = scandir($dir);
$files = array_diff($allFiles, array('.', '..')); // To remove . and .. 

foreach($files as $file){
     echo "<a href='download.php?file=".$file."'>".$file."</a><br>";
}

The scandir() function list all files and directories inside the specified path. It works with both PHP 5 and PHP 7.

Now in the download.php

<?php
$filename = basename($_GET['file']);
// Specify file path.
$path = ''; // '/uplods/'
$download_file =  $path.$filename;

if(!empty($filename)){
    // Check file is exists on given path.
    if(file_exists($download_file))
    {
      header('Content-Disposition: attachment; filename=' . $filename);  
      readfile($download_file); 
      exit;
    }
    else
    {
      echo 'File does not exists on given path';
    }
 }

string=str(input("Enter any sentence: "))
s=string.split()
a=0
b=0

for i in s:
    a=len(i)
    b=a+b

print(b)

It works perfectly without counting spaces of a string

in my case, removing selection of target membership and then select again fix the issue.

Check William Cerniuk answer with the attachment photo.

You can use the markup below, but note that if you set the textAllCaps to true the underline effect would be removed.

<resource>
    <string name="my_string_value">I am <u>underlined</u>.</string>
</resources>

Note

Using textAllCaps with a string (login_change_settings) that contains markup; the markup will be dropped by the caps conversion

The textAllCaps text transform will end up calling toString on the CharSequence, which has the net effect of removing any markup such as . This check looks for usages of strings containing markup that also specify textAllCaps=true.

Joe's answer (Joe Jun 26 '09 at 17:26) does it for me. The simple answer is that absence of an @XmlRootElement annotation is no problem if you marshal a JAXBElement. The thing that confused me is the generated ObjectFactory has 2 createMyRootElement methods - the first takes no parameters and gives the unwrapped object, the second takes the unwrapped object and returns it wrapped in a JAXBElement, and marshalling that JAXBElement works fine. Here's the basic code I used (I'm new to this, so apologies if the code's not formatted correctly in this reply), largely cribbed from link text:

ObjectFactory objFactory = new ObjectFactory();
MyRootElement root = objFactory.createMyRootElement();
...
// Set root properties
...
if (!writeDocument(objFactory.createMyRootElement(root), output)) {
    System.err.println("Failed to marshal XML document");
}
...

private boolean writeDocument(JAXBElement document, OutputStream output) {

  Class<?> clazz = document.getValue().getClass();
  try {
    JAXBContext context =
        JAXBContext.newInstance(clazz.getPackage().getName());
    Marshaller m = context.createMarshaller();
    m.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE);
    m.marshal(document, output);
    return true;

  } catch (JAXBException e) {
    e.printStackTrace(System.err);
    return false;
  }
}

Another possible option would be to use Datejs

Then you can do

Date.getDaysInMonth(2009, 9)     

Although adding a library just for this function is overkill, it's always nice to know all the options you have available to you :)

Making changes as below and redeploying on server content type as

Response.ContentType = "application/octet-stream";

This worked for me.

Response.Clear(); 
Response.AddHeader("Content-Disposition", "attachment; filename=" + file.Name); 
Response.AddHeader("Content-Length", file.Length.ToString()); 
Response.ContentType = "application/octet-stream"; 
Response.WriteFile(file.FullName); 
Response.End();

If you have enum

enum Diet {
  KETO = "Ketogenic",
  ATKINS = "Atkins",
  PALEO = "Paleo",
  DGAF = "Whatever"
}

Then you can get key and values like:

Object.keys(Diet).forEach((d: Diet) => {
  console.log(d); // KETO
  console.log(Diet[d]) // Ketogenic
});

valign="top" should do the work.

<tr>_x000D_
  <td valign="top">Description</td>_x000D_
</tr>

I'd like to clarify a few things:

1. As other answers have pointed out, the simplest thing to do is use pandas.Series.tolist(). I'm not sure why the top voted answer leads off with using pandas.Series.values.tolist() since as far as I can tell, it adds syntax/confusion with no added benefit.
2. tst[lookupValue][['SomeCol']] is a dataframe (as stated in the question), not a series (as stated in a comment to the question). This is because tst[lookupValue] is a dataframe, and slicing it with [['SomeCol']] asks for a list of columns (that list that happens to have a length of 1), resulting in a dataframe being returned. If you remove the extra set of brackets, as in tst[lookupValue]['SomeCol'], then you are asking for just that one column rather than a list of columns, and thus you get a series back.
3. You need a series to use pandas.Series.tolist(), so you should definitely skip the second set of brackets in this case. FYI, if you ever end up with a one-column dataframe that isn't easily avoidable like this, you can use pandas.DataFrame.squeeze() to convert it to a series.
4. tst[lookupValue]['SomeCol'] is getting a subset of a particular column via chained slicing. It slices once to get a dataframe with only certain rows left, and then it slices again to get a certain column. You can get away with it here since you are just reading, not writing, but the proper way to do it is tst.loc[lookupValue, 'SomeCol'] (which returns a series).
5. Using the syntax from #4, you could reasonably do everything in one line: ID = tst.loc[tst['SomeCol'] == 'SomeValue', 'SomeCol'].tolist()

Demo Code:

import pandas as pd
df = pd.DataFrame({'colA':[1,2,1],
                   'colB':[4,5,6]})
filter_value = 1

print "df"
print df
print type(df)

rows_to_keep = df['colA'] == filter_value
print "\ndf['colA'] == filter_value"
print rows_to_keep
print type(rows_to_keep)

result = df[rows_to_keep]['colB']
print "\ndf[rows_to_keep]['colB']"
print result
print type(result)

result = df[rows_to_keep][['colB']]
print "\ndf[rows_to_keep][['colB']]"
print result
print type(result)

result = df[rows_to_keep][['colB']].squeeze()
print "\ndf[rows_to_keep][['colB']].squeeze()"
print result
print type(result)

result = df.loc[rows_to_keep, 'colB']
print "\ndf.loc[rows_to_keep, 'colB']"
print result
print type(result)

result = df.loc[df['colA'] == filter_value, 'colB']
print "\ndf.loc[df['colA'] == filter_value, 'colB']"
print result
print type(result)

ID = df.loc[rows_to_keep, 'colB'].tolist()
print "\ndf.loc[rows_to_keep, 'colB'].tolist()"
print ID
print type(ID)

ID = df.loc[df['colA'] == filter_value, 'colB'].tolist()
print "\ndf.loc[df['colA'] == filter_value, 'colB'].tolist()"
print ID
print type(ID)

Result:

df
   colA  colB
0     1     4
1     2     5
2     1     6
<class 'pandas.core.frame.DataFrame'>

df['colA'] == filter_value
0     True

df[rows_to_keep][['colB']].squeeze()
0    4

df.loc[rows_to_keep, 'colB']
0    4
2    6
Name: colB, dtype: int64
<class 'pandas.core.series.Series'>

df.loc[df['colA'] == filter_value, 'colB']
0    4
2    6
Name: colB, dtype: int64
<class 'pandas.core.series.Series'>

df.loc[rows_to_keep, 'colB'].tolist()
[4, 6]
<type 'list'>

df.loc[df['colA'] == filter_value, 'colB'].tolist()
[4, 6]
<type 'list'>

Might the UNION operator work for you? Have one SELECT for each section, then UNION them together. Guess it would only work for a fixed number of sections though.

<a class="menu_links" onclick="displayData(11,1,0,'A')" onmouseover="" style="cursor: pointer;"> A </a>

It's css.

Or in a style sheet:

a.menu_links { cursor: pointer; }

Here's another solution that mixes ideas from the previous answers. It takes the "kill process" approach while addressing the concern about platform independence.

It relies on the tree-kill package to handle killing the server process tree. I found killing the entire process tree necessary in my projects because some tools (e.g. babel-node) spawn child processes. If you only need to kill a single process, you can replace tree-kill with the built-in process.kill() method.

The solution follows (the first two arguments to spawn() should be modified to reflect the specific recipe for running your server):

build/start-server.js

import { spawn } from 'child_process'
import fs from 'fs'

const child = spawn('node', [
  'dist/server.js'
], {
  detached: true,
  stdio: 'ignore'
})
child.unref()

if (typeof child.pid !== 'undefined') {
  fs.writeFileSync('.server.pid', child.pid, {
    encoding: 'utf8'
  })
}

build/stop-server.js

import fs from 'fs'
import kill from 'tree-kill'

const serverPid = fs.readFileSync('.server.pid', {
  encoding: 'utf8'
})
fs.unlinkSync('.server.pid')

kill(serverPid)

package.json

"scripts": {
  "start": "babel-node build/start-server.js",
  "stop": "babel-node build/stop-server.js"
}

Note that this solution detaches the start script from the server (i.e. npm start will return immediately and not block until the server is stopped). If you prefer the traditional blocking behavior, simply remove the options.detached argument to spawn() and the call to child.unref().

Note also that if you have wordpress just scroll down to the bottom of the webpage when in edit mode, and select "featured image" (bottom right side of screen).

2. Edit as required

PS. I would rather have it implemented in Chrome as a flag preserve after reload, cannot do this now, forums and discussion groups blocked on corporate network :)

In my case I wanted my field to have leading 0's in 10 character field (NVARCHAR(10)). The source file does not have the leading 0's needed to then join to in another table. Did this simply due to being on SQL Server 2008R2:

Set Field = right(('0000000000' + [Field]),10) (Can't use Format() as this is pre SQL2012)

Performed this against the existing data. So this way 1 or 987654321 will still fill all 10 spaces with leading 0's.

As the new data is being imported & then dumped to the table through an Access database, I am able to use Format([Field],"0000000000") when appending from Access to the SQL server table for any new records.

For the same error in wamp/phpmyadmin, I have edited my.ini, commented the original :

;sql-mode= "STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER"

and added sql_mode = "".

When you use scanner, as mentioned by Alnitak, you only get 'false' for hasNext() when you have a EOF character, basically... You cannot easily send and EOF character using the keyboard, therefore in situations like this, it's common to have a special character or word which you can send to stop execution, for example:

String s1 = sc.next();
if (s1.equals("exit")) {
    break;
}

Break will get you out of the loop.

this website shows several formatting options.

Example:

SELECT CONVERT(VARCHAR(10), GETDATE(), 105) 

Sets new value for backgroundPosition on the carousel div when a li in the submenu div is hovered. Removes the backgroundPosition when hovering ends and resets backgroundPosition to old value.

$('#submenu li').hover(function() {
    if ($('#carousel').data('oldbackgroundPosition')==undefined) {
        $('#carousel').data('oldbackgroundPosition', $('#carousel').css('backgroundPosition'));
    }
    $('#carousel').css('backgroundPosition', [enternewvaluehere]);
},
function() {
    var reset = '';
    if ($('#carousel').data('oldbackgroundPosition') != undefined) {
        reset = $('#carousel').data('oldbackgroundPosition');
        $('#carousel').removeData('oldbackgroundPosition');
    }
    $('#carousel').css('backgroundPosition', reset);
});

Another easy way to get epsilon is:

In [1]: 7./3 - 4./3 -1
Out[1]: 2.220446049250313e-16

To get the currently logged in user path:

System.getProperty("user.home");

I had a horrible problem with this so I finally resorted to using LINQ to order the DataTable before assigning it to the view:

Dim lquery = From s In listToMap
             Select s
             Order By s.ACCT_Active Descending, s.ACCT_Name

In particular I really found the DataView.Sort and DataGrid.Sort methods unreliable when sorting a boolean field.

I hope this helps someone out there.

In reply to Is there a specific reason?, here is one interesting application: breaking out of multiple levels of looping.

Here is how it works: the outer loop has a break at the end, so it would only be executed once. However, if the inner loop completes (finds no divisor), then it reaches the else statement and the outer break is never reached. This way, a break in the inner loop will break out of both loops, rather than just one.

for k in [2, 3, 5, 7, 11, 13, 17, 25]:
    for m in range(2, 10):
        if k == m:
            continue
        print 'trying %s %% %s' % (k, m)
        if k % m == 0:
            print 'found a divisor: %d %% %d; breaking out of loop' % (k, m)
            break
    else:
        continue
    print 'breaking another level of loop'
    break
else:
    print 'no divisor could be found!'

For both while and for loops, the else statement is executed at the end, unless break was used.

In most cases there are better ways to do this (wrapping it into a function or raising an exception), but this works!

To add new ViewController once you have have an existing ViewController, follow below step:

1. Click on background of Main.storyboard.

2. Search and select ViewController from object library at the utility window.

3. Drag and drop it in background to create a new ViewController.

Put your code in handler as follows,

public void timerDelayRunForScroll(long time) {
        Handler handler = new Handler(); 
        handler.postDelayed(new Runnable() {           
            public void run() {   
                try {
                    lstView.smoothScrollToPosition(YOUR_POSITION);
                } catch (Exception e) {}
            }
        }, time); 
    }

and then call this method like,

timerDelayRunForScroll(100);

CHEERS!!!

Perhaps you're asking about the DOM methods appendChild and insertBefore.

parentNode.insertBefore(newChild, refChild)

Inserts the node newChild as a child of parentNode before the existing child node refChild. (Returns newChild.)

If refChild is null, newChild is added at the end of the list of children. Equivalently, and more readably, use parentNode.appendChild(newChild).

It seems i came late to the party, but you should better check this out too.

So in system.web for caching up exceptions within the application such as return HttpNotFound()

  <system.web>
    <customErrors mode="RemoteOnly">
      <error statusCode="404" redirect="/page-not-found" />
      <error statusCode="500" redirect="/internal-server-error" />
    </customErrors>
  </system.web>

and in system.webServer for catching up errors that were caught by IIS and did not made their way to the asp.net framework

 <system.webServer>
    <httpErrors errorMode="DetailedLocalOnly">
      <remove statusCode="404"/>
      <error statusCode="404" path="/page-not-found" responseMode="Redirect"/>
      <remove statusCode="500"/>
      <error statusCode="500" path="/internal-server-error" responseMode="Redirect"/>
  </system.webServer>

In the last one if you worry about the client response then change the responseMode="Redirect" to responseMode="File" and serve a static html file, since this one will display a friendly page with an 200 response code.

Taken from the MySQL 8.0 Reference Manual:

• utf8mb4: A UTF-8 encoding of the Unicode character set using one to four bytes per character.

• utf8mb3: A UTF-8 encoding of the Unicode character set using one to three bytes per character.

In MySQL utf8 is currently an alias for utf8mb3 which is deprecated and will be removed in a future MySQL release. At that point utf8 will become a reference to utf8mb4.

So regardless of this alias, you can consciously set yourself an utf8mb4 encoding.

To complete the answer, I'd like to add the @WilliamEntriken's comment below (also taken from the manual):

To avoid ambiguity about the meaning of utf8, consider specifying utf8mb4 explicitly for character set references instead of utf8.

If you want to see screen in Console then you have to write command

 Screen -ls

if you have to access the screen then you have to use below command

 screen -x screen id

Write PWD in command line to check at which folder you are currently

.zip    application/zip, application/octet-stream

memberOf (in AD) is stored as a list of distinguishedNames. Your filter needs to be something like:

(&(objectCategory=user)(memberOf=cn=MyCustomGroup,ou=ouOfGroup,dc=subdomain,dc=domain,dc=com))

If you don't yet have the distinguished name, you can search for it with:

(&(objectCategory=group)(cn=myCustomGroup))

and return the attribute distinguishedName. Case may matter.

Contents of that jQuery object are plain DOM elements, which doesn't respond to jQuery methods (e.g. .attr). You need to wrap the value by $() to turn it into a jQuery object to use it.

    console.info("cat_id: ", $(value).attr('cat_id'));

or just use the DOM method directly

    console.info("cat_id: ", value.getAttribute('cat_id'));

Based on @YOU's answer but keeping the order:

var arr3 = [];
for(var i in arr1){
   var shared = false;
   for (var j in arr2)
       if (arr2[j].name == arr1[i].name) {
           arr3.push(arr1[j]
           shared = true;
           break;
       }
   if(!shared) arr3.push(arr1[i])
}

for(var j in arr2){
   var shared = false;
   for (var i in arr1)
       if (arr2[j].name == arr1[i].name) {
           shared = true;
           break;
       }
   if(!shared) arr3.push(arr2[j])
}
arr3

I know this solution is less efficient, but it's necessary if you want to keep the order and still update the objects.
