Programs & Examples On #Postback

In this case add id to the button in RowDataBound of the grid. It will solve your problem.

You can get a form value posted to a page using code similiar to this (C#) -

string formValue;
if (!string.IsNullOrEmpty(Request.Form["txtFormValue"]))
{
  formValue= Request.Form["txtFormValue"];
}

or this (VB)

Dim formValue As String
If Not String.IsNullOrEmpty(Request.Form("txtFormValue")) Then
    formValue = Request.Form("txtFormValue")
End If

Once you have the values you need you can then construct a SQL statement and and write the data to a database.

Using __doPostBack directly is sooooo the 2000s. Anybody coding WebForms in 2018 uses GetPostBackEventReference

(More seriously though, adding this as an answer for completeness. Using the __doPostBack directly is bad practice (single underscore prefix typically indicates a private member and double indicates a more universal private member), though it probably won't change or become obsolete at this point. We have a fully supported mechanism in ClientScriptManager.GetPostBackEventReference.)

Assuming your btnRefresh is inside our UpdatePanel and causes a postback, you can use GetPostBackEventReference like this (inspiration):

function RefreshGrid() {
    <%= ClientScript.GetPostBackEventReference(btnRefresh, String.Empty) %>;
}

Like others have said, you need to provide the UniqueID of the control to the __doPostback() method.

__doPostBack('<%= btn.UniqueID %>', '');

On the server, the submitted form values are identified by the name attribute of the fields in the page.

The reason why UniqueID works is because UniqueID and name are in fact the same thing when the server control is rendered in HTML.

Here's an article that describes what is the UniqueID:

The UniqueID property is also used to provide value for the HTML "name" attribute of input fields (checkboxes, dropdown lists, and hidden fields). UniqueID also plays major role in postbacks. The UniqueID property of a server control, which supports postbacks, provides data for the __EVENTTARGET hidden field. The ASP.NET Runtime then uses the __EVENTTARGET field to find the control which triggered the postback and then calls its RaisePostBackEvent method.

ken's answer above did the trick for me. The problem with the accepted answer is that it only works if you have a single modal on the page. If you have multiple modals, you'll need to do it inline in the "open" param while initializing the dialog, not after the fact.

open: function(type,data) { $(this).parent().appendTo("form"); }

If you do what the first accepted answer tells you with multiple modals, you'll only get the last modal on the page working firing postbacks properly, not all of them.

For MVC, ignore input validation by adding

[ValidateInput(false)]

above each Action in the Controller.

There are solutions here that will work, but I don't see anyone explaining what is actually happening here, so even though this is 2 years old I'll explain it.

There is nothing "wrong" with the onclientclick javascript you are adding. The problem is that asp.net is adding it's on onclick stuff to run AFTER whatever code you put in there runs.

So for example this ASPX:

<asp:Button ID="btnDeny" runat="server" CommandName="Deny" Text="Mark 'Denied'" OnClientClick="return confirm('Are you sure?');" />

is turned into this HTML when rendered:

<input name="rgApplicants$ctl00$ctl02$ctl00$btnDeny" id="rgApplicants_ctl00_ctl02_ctl00_btnDeny" 
onclick="return confirm('Are you sure?');__doPostBack('rgApplicants$ctl00$ctl02$ctl00$btnDeny','')" type="button" value="Mark 'Denied'" abp="547">

If you look closely, the __doPostBack stuff will never be reached, because the "confirm" will always return true/false before __doPostBack is reached.

This is why you need to have the confirm only return false and not return when the value is true. Technically, it doesn't matter if it returns true or false, any return in this instance would have the effect of preventing the __doPostBack from being called, but for convention I would leave it so that it returns false when false and does nothing for true.

What if you don't immediately set the button to disabled, but delay that through setTimeout? Your 'disable' function would return and the submit would continue.

Here the solution from http://forums.asp.net/t/928411.aspx/1 as mentioned by mamoo - just in case the website goes offline. Worked well for me.

StringBuilder sbScript = new StringBuilder();

sbScript.Append("<script language='JavaScript' type='text/javascript'>\n");
sbScript.Append("<!--\n");
sbScript.Append(this.GetPostBackEventReference(this, "PBArg") + ";\n");
sbScript.Append("// -->\n");
sbScript.Append("</script>\n");

this.RegisterStartupScript("AutoPostBackScript", sbScript.ToString());

Here are screenshots for SQL Server 2008 R2, using SSRS Report Designer in Visual Studio 2010.

I have done screenshots as some of the dialogs are not easy to find.

1: Add the group

2: Specify the field you want to group on

3: Now click on the group in the 'Row Groups' selector, directly below the report designer

4: F4 to select property pane; expand 'Group' and set Group > PageBreak > BreakLocation = 'Between', then enter the expression you want for Group > PageName

5: Here is an example expression

Here is the result of the report exported to Excel, with tabs named according to the PageName expression

JUnit 5 now has a @BeforeAll annotation:

Denotes that the annotated method should be executed before all @Test methods in the current class or class hierarchy; analogous to JUnit 4’s @BeforeClass. Such methods must be static.

The lifecycle annotations of JUnit 5 seem to have finally gotten it right! You can guess which annotations available without even looking (e.g. @BeforeEach @AfterAll)

Its simple way

>>import json 
>>from collection import OrderedDict

>>json.dumps(dict(OrderedDict([('method', 'constant'), ('data', '1.225')])))

You can specify a width on string fields, e.g.

printf("%-20s", "initialization...");

And then whatever's printed with that field will be blank-padded to the width you indicate.

The - left-justifies your text in that field.

Python dictionaries are unordered. If you want an ordered dictionary, use collections.OrderedDict

In your case, sort the dict by key before plotting,

import matplotlib.pylab as plt

lists = sorted(d.items()) # sorted by key, return a list of tuples

x, y = zip(*lists) # unpack a list of pairs into two tuples

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

Here is the result.

Similar to the other examples, but using html sizing, I use:

<img src="image1.png" width="425"/> <img src="image2.png" width="425"/> 

Here is an example

<img src="https://openclipart.org/image/2400px/svg_to_png/28580/kablam-Number-Animals-1.png" width="200"/> <img src="https://openclipart.org/download/71101/two.svg" width="300"/>

I tested this using Remarkable.

Ensure that your 3rd party jars are in your projects "libs" folder and they will be put in the .apk when you package your application. You may see runtime errors on the device if something in the jar is not supported, but other than that I have had great success with this.

I've used this successfully inside R script:

library("reshape2",lib.loc="/path/to/R-packages/")

useful if for whatever reason libraries are in more than one place.

Either use an Allias in the table like T and use T.ID, or use just the column name.

declare @TEMP table (ID int, Name varchar(max))
insert into @temp SELECT ID, Name FROM Table

SELECT * FROM @TEMP 
WHERE ID  = 1 

I just ran into this and it was due to a mod_authnz_ldap misconfiguration in my .htaccess file. Absolutely nothing was being logged, but I kept getting a 500 error.

If you run into this particular issue, you can change the log level of mod_authnz_ldap like so:

LogLevel warn authnz_ldap_module:debug

That will use a log level of debug for mod_authnz_ldap but warn for everything else (https://httpd.apache.org/docs/2.4/en/mod/core.html#loglevel).

As an option you can initially create Null-able column, then update your table column with valid not null values and finally ALTER column to set NOT NULL constraint:

ALTER TABLE MY_TABLE ADD STAGE INT NULL
GO
UPDATE MY_TABLE SET <a valid not null values for your column>
GO
ALTER TABLE MY_TABLE ALTER COLUMN STAGE INT NOT NULL
GO

Another option is to specify correct default value for your column:

ALTER TABLE MY_TABLE ADD STAGE INT NOT NULL DEFAULT '0'

UPD: Please note that answer above contains GO which is a must when you run this code on Microsoft SQL server. If you want to perform the same operation on Oracle or MySQL you need to use semicolon ; like that:

ALTER TABLE MY_TABLE ADD STAGE INT NULL;
UPDATE MY_TABLE SET <a valid not null values for your column>;
ALTER TABLE MY_TABLE ALTER COLUMN STAGE INT NOT NULL;

Make sure these references are included:

• System.Data.Linq
• System.Data.Entity

Then add the using statement

You can roughly think of any and all as series of logical or and and operators, respectively.

any

any will return True when at least one of the elements is Truthy. Read about Truth Value Testing.

all

all will return True only when all the elements are Truthy.

Truth table

+-----------------------------------------+---------+---------+
|                                         |   any   |   all   |
+-----------------------------------------+---------+---------+
| All Truthy values                       |  True   |  True   |
+-----------------------------------------+---------+---------+
| All Falsy values                        |  False  |  False  |
+-----------------------------------------+---------+---------+
| One Truthy value (all others are Falsy) |  True   |  False  |
+-----------------------------------------+---------+---------+
| One Falsy value (all others are Truthy) |  True   |  False  |
+-----------------------------------------+---------+---------+
| Empty Iterable                          |  False  |  True   |
+-----------------------------------------+---------+---------+

Note 1: The empty iterable case is explained in the official documentation, like this

any

Return True if any element of the iterable is true. If the iterable is empty, return False

Since none of the elements are true, it returns False in this case.

all

Return True if all elements of the iterable are true (or if the iterable is empty).

Since none of the elements are false, it returns True in this case.

Note 2:

Another important thing to know about any and all is, it will short-circuit the execution, the moment they know the result. The advantage is, entire iterable need not be consumed. For example,

>>> multiples_of_6 = (not (i % 6) for i in range(1, 10))
>>> any(multiples_of_6)
True
>>> list(multiples_of_6)
[False, False, False]

Here, (not (i % 6) for i in range(1, 10)) is a generator expression which returns True if the current number within 1 and 9 is a multiple of 6. any iterates the multiples_of_6 and when it meets 6, it finds a Truthy value, so it immediately returns True, and rest of the multiples_of_6 is not iterated. That is what we see when we print list(multiples_of_6), the result of 7, 8 and 9.

This excellent thing is used very cleverly in this answer.

With this basic understanding, if we look at your code, you do

any(x) and not all(x)

which makes sure that, atleast one of the values is Truthy but not all of them. That is why it is returning [False, False, False]. If you really wanted to check if both the numbers are not the same,

print [x[0] != x[1] for x in zip(*d['Drd2'])]

TL;DR

Use the nargs option or the 'append' setting of the action option (depending on how you want the user interface to behave).

nargs

parser.add_argument('-l','--list', nargs='+', help='<Required> Set flag', required=True)
# Use like:
# python arg.py -l 1234 2345 3456 4567

nargs='+' takes 1 or more arguments, nargs='*' takes zero or more.

append

parser.add_argument('-l','--list', action='append', help='<Required> Set flag', required=True)
# Use like:
# python arg.py -l 1234 -l 2345 -l 3456 -l 4567

With append you provide the option multiple times to build up the list.

Don't use type=list!!! - There is probably no situation where you would want to use type=list with argparse. Ever.

Let's take a look in more detail at some of the different ways one might try to do this, and the end result.

import argparse

parser = argparse.ArgumentParser()

# By default it will fail with multiple arguments.
parser.add_argument('--default')

# Telling the type to be a list will also fail for multiple arguments,
# but give incorrect results for a single argument.
parser.add_argument('--list-type', type=list)

# This will allow you to provide multiple arguments, but you will get
# a list of lists which is not desired.
parser.add_argument('--list-type-nargs', type=list, nargs='+')

# This is the correct way to handle accepting multiple arguments.
# '+' == 1 or more.
# '*' == 0 or more.
# '?' == 0 or 1.
# An int is an explicit number of arguments to accept.
parser.add_argument('--nargs', nargs='+')

# To make the input integers
parser.add_argument('--nargs-int-type', nargs='+', type=int)

# An alternate way to accept multiple inputs, but you must
# provide the flag once per input. Of course, you can use
# type=int here if you want.
parser.add_argument('--append-action', action='append')

# To show the results of the given option to screen.
for _, value in parser.parse_args()._get_kwargs():
    if value is not None:
        print(value)

Here is the output you can expect:

$ python arg.py --default 1234 2345 3456 4567
...
arg.py: error: unrecognized arguments: 2345 3456 4567

$ python arg.py --list-type 1234 2345 3456 4567
...
arg.py: error: unrecognized arguments: 2345 3456 4567

$ # Quotes won't help here... 
$ python arg.py --list-type "1234 2345 3456 4567"
['1', '2', '3', '4', ' ', '2', '3', '4', '5', ' ', '3', '4', '5', '6', ' ', '4', '5', '6', '7']

$ python arg.py --list-type-nargs 1234 2345 3456 4567
[['1', '2', '3', '4'], ['2', '3', '4', '5'], ['3', '4', '5', '6'], ['4', '5', '6', '7']]

$ python arg.py --nargs 1234 2345 3456 4567
['1234', '2345', '3456', '4567']

$ python arg.py --nargs-int-type 1234 2345 3456 4567
[1234, 2345, 3456, 4567]

$ # Negative numbers are handled perfectly fine out of the box.
$ python arg.py --nargs-int-type -1234 2345 -3456 4567
[-1234, 2345, -3456, 4567]

$ python arg.py --append-action 1234 --append-action 2345 --append-action 3456 --append-action 4567
['1234', '2345', '3456', '4567']

Takeaways:

• Use nargs or action='append'
  • nargs can be more straightforward from a user perspective, but it can be unintuitive if there are positional arguments because argparse can't tell what should be a positional argument and what belongs to the nargs; if you have positional arguments then action='append' may end up being a better choice.
  • The above is only true if nargs is given '*', '+', or '?'. If you provide an integer number (such as 4) then there will be no problem mixing options with nargs and positional arguments because argparse will know exactly how many values to expect for the option.
• Don't use quotes on the command line¹
• Don't use type=list, as it will return a list of lists
  • This happens because under the hood argparse uses the value of type to coerce each individual given argument you your chosen type, not the aggregate of all arguments.
  • You can use type=int (or whatever) to get a list of ints (or whatever)

¹: I don't mean in general.. I mean using quotes to pass a list to argparse is not what you want.

I had the same issue, I found most of the answers here out dated. I ended up writing a wrapper on FFMPEG to access from Android with a single line of code.

In case this helps someone, if you're using Visual Studio Code, it expects the file to be in UTF-8 encoding. To generate the file, I ran pylint --generate-rcfile | out-file -encoding utf8 .pylintrc in PowerShell.

Right-click the project, select Properties then under 'Configuration properties | Linker | Input | Ignore specific Library and write msvcrtd.lib

I had a similar error, my console looked like this:

My problem was that I was running my site in a sub folder since the company was using one top domain and no sub domains. Like this:

host.com/app1

host.com/app2

My code looked like this for including scripts which worked fine on localhost but not in app1 or app2:

<link rel="stylesheet" type="text/css" href="/Content/css/font-awesome.min.css" />

Added a tilde sign ~ to src and then everything worked:

<link rel="stylesheet" type="text/css" href="~/Content/css/font-awesome.min.css" />

Explanation of ~ vs /:

• / - Site root
• ~/ - Root directory of the application

/ will return the root of the site (http://host.com/),

~/ will return the root of the application (http://host.com/app1/).

Running the IDE (in my case IntelliJ) in administrator mode and executing npm install does resolves the problem.

If no IDE then run CMD in administrator mode and try executing npm install

Other answers posted here for this question did not work for me using the latest Visual Studio 2017 Enterprise edition (as of 2018-09-18).

Instead, I used this method:

1. Close all but one instance of Visual Studio.
2. In the running instance, access the menu Tools->Extensions and Updates.
3. In that dialog, choose Online->Visual Studio Marketplace->Tools->Setup & Deployment.
4. From the list that appears, select Microsoft Visual Studio 2017 Installer Projects.

Once installed, close and restart Visual Studio. Go to File->New Project and search for the word Installer. You'll know you have the correct templates installed if you see a list that looks something like this:

Generally i prefer the lambda syntax with LINQ, but Join is one example where i prefer the query syntax - purely for readability.

Nonetheless, here is the equivalent of your above query (i think, untested):

var query = db.Categories         // source
   .Join(db.CategoryMaps,         // target
      c => c.CategoryId,          // FK
      cm => cm.ChildCategoryId,   // PK
      (c, cm) => new { Category = c, CategoryMaps = cm }) // project result
   .Select(x => x.Category);  // select result

You might have to fiddle with the projection depending on what you want to return, but that's the jist of it.

Simple Way from Scratch.

1. Download Anaconda from https://repo.anaconda.com/archive/Anaconda3-5.2.0-Windows-x86_64.exe

2. Install Anaconda by double clicking it.

3. Open anaconda prompt by searching anaconda in windows search and type the following command while being connected to internet.

   A. conda create -n tensorflow_env python=3.6

   B. conda activate tensorflow_env

   C. conda install -c conda-forge tensorflow

Step C will take time. After install type python in conda prompt and type

import tensorflow as tf

If no error is found your installation is successful.

If you are using IIS 7.5 or later you can generate the machine key from IIS and save it directly to your web.config, within the web farm you then just copy the new web.config to each server.

1. Open IIS manager.
2. If you need to generate and save the MachineKey for all your applications select the server name in the left pane, in that case you will be modifying the root web.config file (which is placed in the .NET framework folder). If your intention is to create MachineKey for a specific web site/application then select the web site / application from the left pane. In that case you will be modifying the web.config file of your application.
3. Double-click the Machine Key icon in ASP.NET settings in the middle pane:
4. MachineKey section will be read from your configuration file and be shown in the UI. If you did not configure a specific MachineKey and it is generated automatically you will see the following options:
5. Now you can click Generate Keys on the right pane to generate random MachineKeys. When you click Apply, all settings will be saved in the web.config file.

Full Details can be seen @ Easiest way to generate MachineKey – Tips and tricks: ASP.NET, IIS and .NET development…

Above answer is very correct but I'm giving an easy step to do it:

 private static final long[] THREE_CYCLES = new long[] { 100, 1000, 1000,  1000, 1000, 1000 };

  public void longVibrate(View v) 
  {
     vibrateMulti(THREE_CYCLES);
  }

  private void vibrateMulti(long[] cycles) {
      NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE); 
      Notification notification = new Notification();

      notification.vibrate = cycles; 
      notificationManager.notify(0, notification);
  }

And then in your xml file:

<button android:layout_height="wrap_content" 
        android:layout_width ="wrap_content" 
        android:onclick      ="longVibrate" 
        android:text         ="VibrateThrice">
</button>

That's the easiest way.

I know this is ancient however when dealing with finicky tools, uses, users or symptoms re: sid & service naming one can add a little flex to your tnsnames entries as like:

mySID, mySID.whereever.com =

  (ADDRESS_LIST =
    (ADDRESS = (PROTOCOL = TCP)(HOST = myHostname)(PORT = 1521))
  )
  (CONNECT_DATA =
    (SERVICE_NAME = mySID.whereever.com)
    (SID = mySID)
    (SERVER = DEDICATED)
  )
)

I just thought I'd leave this here as it's mildly relevant to the question and can be helpful when attempting to weave around some less than clear idiosyncrasies of oracle networking.

If you want to use an older version of .net, create your own flag and cast it.

Here you go :

Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/t", "", "");

Statement st = con.createStatement();
String sql = ("SELECT * FROM posts ORDER BY id DESC LIMIT 1;");
ResultSet rs = st.executeQuery(sql);
if(rs.next()) { 
 int id = rs.getInt("first_column_name"); 
 String str1 = rs.getString("second_column_name");
}

con.close();

In rs.getInt or rs.getString you can pass column_id starting from 1, but i prefer to pass column_name as its more informative as you don't have to look at database table for which index is what column.

UPDATE : rs.next

boolean next() throws SQLException

Moves the cursor froward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown. If the result set type is TYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will return false or throw an SQLException on a subsequent call to next.

If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

Returns: true if the new current row is valid; false if there are no more rows Throws: SQLException - if a database access error occurs or this method is called on a closed result set

What about inv?

Open the project you want to push in Android Studio.

Click VCS -> Enable version Control Integration -> Git

There doesn't seem to be a way to add a remote through the GUI. So open Git Bash in the root of the project and do git remote add <remote_name> <remote_url>

Now when you do VCS -> Commit changes -> Commit & Push you should see your remote and everything should work through the GUI.

If you are getting the error: fatal: remote <remote_name> already exists that means you already added it. To see your remotes do git remote -v and git remote rm <remote_name> to remove.

stop.set() 

Or here's the same functionality but as a standalone function instead of a decorator:

cancel_future_calls = call_repeatedly(60, print, "Hello, World")
# ...
cancel_future_calls() 

Here's how to do it without using threads.

I tried following options to fix this issue and it worked.

1. Uninstall Node.js version 8.
2. Install Node.js version 6.11.4
3. Use the registry option along with command to install any package.

For example to install express I used following command.

npm install express --registry http://registry.npmjs.org/

or

npm install express -g --registry http://registry.npmjs.org/

If you want to install locally in any specific folder then use below command. Below command will install express on path C:\Sample\Example1 .

C:\Sample1\Example1> npm install /Sample/Example1 express --registry http://registry.npmjs.org/

Note: If you are installing locally in a specific location then first go to that directory using command and then run above command. If you are not inside that directory and giving only path in command that will not work.

If you get package.json missing error then run below command before installing package locally

C:\Sample\Example1> npm init

above command will create package.json file. No need to provide any data. just hit enter.

Note: If you are behind a firewall then you may need to set a proxy.

In SQL Server 2012+, you can use OFFSET...FETCH:

SELECT
   <column(s)>
FROM
   <table(s)>
ORDER BY
   <sort column(s)>
OFFSET 1 ROWS   -- Skip this number of rows
FETCH NEXT 1 ROWS ONLY;  -- Return this number of rows

You got the first part right:

Yes mapStateToProps has the Store state as an argument/param (provided by react-redux::connect) and its used to link the component with certain part of the store state.

By linking I mean the object returned by mapStateToProps will be provided at construction time as props and any subsequent change will be available through componentWillReceiveProps.

If you know the Observer design pattern it's exactly that or small variation of it.

An example would help make things clearer:

import React, {
    Component,
} from 'react-native';

class ItemsContainer extends Component {
    constructor(props) {
        super(props);

        this.state = {
            items: props.items, //provided by connect@mapStateToProps
            filteredItems: this.filterItems(props.items, props.filters),
        };
    }

    componentWillReceiveProps(nextProps) {
        this.setState({
            filteredItems: this.filterItems(this.state.items, nextProps.filters),
        });
    }

    filterItems = (items, filters) => { /* return filtered list */ }

    render() {
        return (
            <View>
                // display the filtered items
            </View>
        );
    }
}

module.exports = connect(
    //mapStateToProps,
    (state) => ({
        items: state.App.Items.List,
        filters: state.App.Items.Filters,
        //the State.App & state.App.Items.List/Filters are reducers used as an example.
    })
    // mapDispatchToProps,  that's another subject
)(ItemsContainer);

There can be another react component called itemsFilters that handle the display and persisting the filter state into Redux Store state, the Demo component is "listening" or "subscribed" to Redux Store state filters so whenever filters store state changes (with the help of filtersComponent) react-redux detect that there was a change and notify or "publish" all the listening/subscribed components by sending the changes to their componentWillReceiveProps which in this example will trigger a refilter of the items and refresh the display due to the fact that react state has changed.

Let me know if the example is confusing or not clear enough to provide a better explanation.

As for: This means that the state as consumed by your target component can have a wildly different structure from the state as it is stored on your store.

I didn't get the question, but just know that the react state (this.setState) is totally different from the Redux Store state!

The react state is used to handle the redraw and behavior of the react component. The react state is contained to the component exclusively.

The Redux Store state is a combination of Redux reducers states, each is responsible of managing a small portion app logic. Those reducers attributes can be accessed with the help of react-redux::connect@mapStateToProps by any component! Which make the Redux store state accessible app wide while component state is exclusive to itself.

Using class members to give default values works very well just so long as you are careful only to do it with immutable values. If you try to do it with a list or a dict that would be pretty deadly. It also works where the instance attribute is a reference to a class just so long as the default value is None.

I've seen this technique used very successfully in repoze which is a framework that runs on top of Zope. The advantage here is not just that when your class is persisted to the database only the non-default attributes need to be saved, but also when you need to add a new field into the schema all the existing objects see the new field with its default value without any need to actually change the stored data.

I find it also works well in more general coding, but it's a style thing. Use whatever you are happiest with.

You can simply subclass UIButton and write your own drawing code to suit your needs. I implemented a radio button like that of android using the following code. It can be used in storyboard as well.See example in Github repo

import UIKit

@IBDesignable
class SPRadioButton: UIButton {

@IBInspectable
var gap:CGFloat = 8 {
    didSet {
        self.setNeedsDisplay()
    }
}

@IBInspectable
var btnColor: UIColor = UIColor.green{
    didSet{
        self.setNeedsDisplay()
    }
}

@IBInspectable
var isOn: Bool = true{
    didSet{
        self.setNeedsDisplay()
    }
}

override func draw(_ rect: CGRect) {
    self.contentMode = .scaleAspectFill
    drawCircles(rect: rect)
}


//MARK:- Draw inner and outer circles
func drawCircles(rect: CGRect){
    var path = UIBezierPath()
    path = UIBezierPath(ovalIn: CGRect(x: 0, y: 0, width: rect.width, height: rect.height))

    let circleLayer = CAShapeLayer()
    circleLayer.path = path.cgPath
    circleLayer.lineWidth = 3
    circleLayer.strokeColor = btnColor.cgColor
    circleLayer.fillColor = UIColor.white.cgColor
    layer.addSublayer(circleLayer)

    if isOn {
        let innerCircleLayer = CAShapeLayer()
        let rectForInnerCircle = CGRect(x: gap, y: gap, width: rect.width - 2 * gap, height: rect.height - 2 * gap)
        innerCircleLayer.path = UIBezierPath(ovalIn: rectForInnerCircle).cgPath
        innerCircleLayer.fillColor = btnColor.cgColor
        layer.addSublayer(innerCircleLayer)
    }
    self.layer.shouldRasterize =  true
    self.layer.rasterizationScale = UIScreen.main.nativeScale
}

/*
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
    isOn = !isOn
    self.setNeedsDisplay()
}
*/    

override func awakeFromNib() {
    super.awakeFromNib()
    addTarget(self, action: #selector(buttonClicked(sender:)), for: UIControl.Event.touchUpInside)
    isOn = false
}

@objc func buttonClicked(sender: UIButton) {
    if sender == self {
        isOn = !isOn
        setNeedsDisplay()
    }
}
}

To add some text, what I did some time ago , if the link you are sharing its a page you can modify. You can add some meta-tags to the shared page:

<meta name="title" content="The title you want" />
<meta name="description" content="The text you want to insert " />
<link rel="image_src" href="A thumbnail you can show" / >

It's a small hack. Although the old share button has been replaced by the "like"/"recommend" button where you can add a comment if you use the XFBML version. More info her:

2 things.

• The query has to complete on sql server before the return value is sent.

• The results have to be captured and then finish executing before the return value gets to the object.

In English, finish the work and then retrieve the value.

this will not work:

                cmm.ExecuteReader();
                int i = (int) cmm.Parameters["@RETURN_VALUE"].Value;

This will work:

                        SqlDataReader reader = cmm.ExecuteReader();
                        reader.Close();

                        foreach (SqlParameter prm in cmd.Parameters)
                        {
                           Debug.WriteLine("");
                           Debug.WriteLine("Name " + prm.ParameterName);
                           Debug.WriteLine("Type " + prm.SqlDbType.ToString());
                           Debug.WriteLine("Size " + prm.Size.ToString());
                           Debug.WriteLine("Direction " + prm.Direction.ToString());
                           Debug.WriteLine("Value " + prm.Value);

                        }

if you are not sure check the value of the parameter before during and after the results have been processed by the reader.

The only thing which worked for me is this

fetchData()
  .subscribe(
    (data) => {
       //Called when success
     },
    (error) => {
       //Called when error
    }
  ).add(() => {
       //Called when operation is complete (both success and error)
  });

It is possible to define a urlBasedViewResolver in your properties file:

excel.(class)=fi.utu.seurantaraporttisuodatin.service.Raportti  
index.(class)=org.springframework.web.servlet.view.urlBasedView  
index.viewClass =org.springframework.web.servlet.view.JstlView  
index.prefix = /WEB-INF/jsp/  
index.suffix =.jsp

Use Connection.isClosed() function.

The JavaDoc states:

Retrieves whether this Connection object has been closed. A connection is closed if the method close has been called on it or if certain fatal errors have occurred. This method is guaranteed to return true only when it is called after the method Connection.close has been called.

Signing Your App in Android Studio

To sign your app in release mode in Android Studio, follow these steps:

1- On the menu bar, click Build > Generate Signed APK.

2-On the Generate Signed APK Wizard window, click Create new to create a new keystore. If you already have a keystore, go to step 4.

3- On the New Key Store window, provide the required information as shown in figure Your key should be valid for at least 25 years, so you can sign app updates with the same key through the lifespan of your app.

4- On the Generate Signed APK Wizard window, select a keystore, a private key, and enter the passwords for both. Then click Next.

5- On the next window, select a destination for the signed APK and click Finish.

The purpose is typically just to restrict the scope of the nested class. Nested classes compared to normal classes have the additional possibility of the private modifier (as well as protected of course).

Basically, if you only need to use this class from within the "parent" class (in terms of scope), then it is usually appropiate to define it as a nested class. If this class might need to be used from without the assembly/library, then it is usually more convenient to the user to define it as a separate (sibling) class, whether or not there is any conceptual relationship between the two classes. Even though it is technically possible to create a public class nested within a public parent class, this is in my opinion rarely an appropiate thing to implement.

Use REPLACE:

SELECT REPLACE(t.column, 'est1', 'rest1')
  FROM MY_TABLE t

If you want to update the values in the table, use:

UPDATE MY_TABLE t
   SET column = REPLACE(t.column, 'est1', 'rest1')

For any newcomers, as of April 2015, Android now has a SortedList class in the support library, designed specifically to work with RecyclerView. Here's the blog post about it.

The tricky part here is to handle is the page event. We can follow angular material documentation up to defining page event function.

Visit https://material.angular.io/components/paginator/examples for the reference.

I will add my work with hours of hard work in this regard. in the relevant HTML file should look like as follows,

<pre>
<mat-paginator
    [pageSizeOptions]="pageSizeOptions"
    [pageSize]="Size"
    (page)="pageEvent = pageNavigations($event)"
    [length]="recordCount">
</mat-paginator>
</pre>

Then go to the relevant typescript file and following code,

declarations,

@Input('data') customers: Observable<Customer[]>;
pageEvent: PageEvent;
Page: number=0;
Size: number=2;
recordCount: number;
pageSizeOptions: number[] = [2,3,4,5];

The key part of page navigation as follows,

pageNavigations(event? : PageEvent){
    console.log(event);
    this.Page = event.pageIndex;
    this.Size = event.pageSize;
    this.reloadData();
  }

We require the following function to call data from the backend.

reloadData() {

    this.customers = this.customerService.setPageSize(this.Page ,this.Size);
    this.customerService.getSize().subscribe(res => {
      this.recordCount = Number(res);
     
      console.log(this.recordCount);
    });
  }

Before the aforementioned implementation, our services file should contain the following service call

setPageSize(page: number, size: number): Observable<any> {
    return this.http.get(`${this.baseUrl}?pageSize=${size}&pageNo=${page}`);
  }

Then all set to go and enable pagination in our app. Feel free to ask related questions thank you.

When a mouse is attached, it can be assumed with fairly high hitrate (I would say practially 100%) that the user moves the mouse at least a tiny distance after page is ready - without any clicking. The mechanism below detects this. If detected, I consider this as a sign of missing touch support or, if supported, of minor importance when a mouse is in use. Touch-device is assumed if not detected.

EDIT This approach may not fit all purposes. It can be used to control functionality that is activated based on user interaction on the loaded page, for instance an image viewer. The code below will also leave the mousemove event bound on devices without mouse as it stands out now. Other approaches may be better.

Roughly, it goes like this (sorry for jQuery, but similar in pure Javascript):

var mousedown, first, second = false;
var ticks = 10;
$(document).on('mousemove', (function(e) {
    if(UI.mousechecked) return;
    if(!first) {
        first = e.pageX;
        return;
        }
    if(!second && ticks-- === 0) {
        second = e.pageX;
        $(document).off('mousemove'); // or bind it to somewhat else
        }
    if(first  && second  && first !== second && !mousedown){
        // set whatever flags you want
        UI.hasmouse = true;
        UI.touch = false;
        UI.mousechecked = true;
    }

    return;
}));
$(document).one('mousedown', (function(e) {
    mousedown = true;
    return;
}));
$(document).one('mouseup', (function(e) {
    mousedown = false;
    return;
}));

You have to be sure to use UIPickerViewDataSource and UIPickerViewDelegate protocols or it will throw an AppDelegate error as of swift 3

Also please take note of the change in syntax:

func numberOfComponentsInPickerView(pickerView: UIPickerView) -> Int

is now:

public func numberOfComponents(in pickerView: UIPickerView) -> Int

The following below worked for me.

import UIkit

class ViewController: UIViewController, UIPickerViewDataSource, UIPickerViewDelegate {

    @IBOutlet weak var textBox: UITextField!
    @IBOutlet weak var dropDown: UIPickerView!

    var list = ["1", "2", "3"]

    public func numberOfComponents(in pickerView: UIPickerView) -> Int{
        return 1
    }

    public func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{

        return list.count
    }

    func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {

        self.view.endEditing(true)
        return list[row]
    }

    func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {

        self.textBox.text = self.list[row]
        self.dropDown.isHidden = true
    }

    func textFieldDidBeginEditing(_ textField: UITextField) {

        if textField == self.textBox {
            self.dropDown.isHidden = false
            //if you don't want the users to se the keyboard type:

            textField.endEditing(true)
        }
    }
}

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

pip install pywin32

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

pip install pywin32==xxx

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

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

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

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

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

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

EDIT

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

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

pip install pypiwin32

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

Once the array size is fixed while running the program ,it's size can't be changed further. So better go for ArrayList while dealing with dynamic arrays.

To follow up on Ron's answer if using JQuery and putting it in application.js or the head section you need to wrap it in a ready() section...

$(document).ready(function() {
  $('#my-link').click(function(event){
    alert('Hooray!');
    event.preventDefault(); // Prevent link from following its href
  });
});

Please remember one thing if you want to use bootstrap tooltip in angularjs is order of your scripts if you are using jquery-ui as well, it should be:

• jQuery
• jQuery UI
• Bootstap

It is tried and tested

Best way to do this is to use a function:

<div ng-repeat="product in products | filter: myFilter">

$scope.myFilter = function (item) { 
    return item === 'red' || item === 'blue'; 
};

Alternatively, you can use ngHide or ngShow to dynamically show and hide elements based on a certain criteria.

clear_btm=Button(master,text="Clear") #this button will delete the widgets 
clear_btm["command"] = lambda one = button1, two = text1, three = entry1: clear(one,two,three) #pass the widgets
clear_btm.pack()

def clear(*widgets):
    for widget in widgets:
        widget.destroy() #finally we are deleting the widgets.

You could use a nested query:

Select
  ColumnA,
  ColumnB,
  calccolumn1,
  calccolumn1 / ColumnC as calccolumn2
From (
  Select
    ColumnA,
    ColumnB,
    ColumnC,
    ColumnA + ColumnB As calccolumn1
  from t42
);

With a row with values 3, 4, 5 that gives:

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4

You can also just repeat the first calculation, unless it's really doing something expensive (via a function call, say):

Select
  ColumnA,
  ColumnB,
  ColumnA + ColumnB As calccolumn1,
  (ColumnA + ColumnB) / ColumnC As calccolumn2
from t42; 

   COLUMNA    COLUMNB CALCCOLUMN1 CALCCOLUMN2
---------- ---------- ----------- -----------
         3          4           7         1.4 

Mail chimp have got quite a nice article on what not to do. ( I know it sounds the wrong way round for what you want)

http://kb.mailchimp.com/article/common-html-email-coding-mistakes

In general all the things that you have learnt that are bad practise for web design seem to be the only option for html email.

The basics are:

• Have absolute paths for images (eg. https://stackoverflow.com/random-image.png)
• Use tables for layout (never thought I'd recommend that!)
• Use inline styles (and old school css too, at the very most 2.1, box-shadow won't work for instance ;) )

Just test in as many email clients as you can get your hands on, or use Litmus as someone else suggested above! (credit to Jim)

EDIT :

Mail chimp have done a great job by making this tool available to the community.

It applies your CSS classes to your html elements inline for you!

In PHP, a variable or array element which has never been set is different from one whose value is null; attempting to access such an unset value is a runtime error.

That's what you're running into: the array $_POST does not have any element at the key "username", so the interpreter aborts your program before it ever gets to the nullity test.

Fortunately, you can test for the existence of a variable or array element without actually trying to access it; that's what the special operator isset does:

if (isset($_POST["username"]))
{
  $user = $_POST["username"];
  echo $user;
  echo " is your username";
} 
else 
{
  $user = null;
  echo "no username supplied";
}

This looks like it will blow up in exactly the same way as your code, when PHP tries to get the value of $_POST["username"] to pass as an argument to the function isset(). However, isset() is not really a function at all, but special syntax recognized before the evaluation stage, so the PHP interpreter checks for the existence of the value without actually trying to retrieve it.

It's also worth mentioning that as runtime errors go, a missing array element is considered a minor one (assigned the E_NOTICE level). If you change the error_reporting level so that notices are ignored, your original code will actually work as written, with the attempted array access returning null. But that's considered bad practice, especially for production code.

Side note: PHP does string interpolation, so the echo statements in the if block can be combined into one:

echo "$user is your username";

Thx guys, I finally found the solution, a really basic one.. In my controller I have

$scope.mySplit = function(string, nb) {
    var array = string.split(',');
    return array[nb];
}

and in my view

{{mySplit(string,0)}}

There are plenty of descriptive answers here so I'm not going to repeat what has already been said. What I would like to add is the following code demonstrating all the permutations I can think of. The code is quite long due to the number of combinations. Feel free to drop it into MSTest and see the output for yourself (the output is included at the bottom).

This evidence supports Jon Skeet's answer.

Virtual Functions are used to support Runtime Polymorphism.

That is, virtual keyword tells the compiler not to make the decision (of function binding) at compile time, rather postpone it for runtime".

• You can make a function virtual by preceding the keyword virtual in its base class declaration. For example,

   class Base
   {
      virtual void func();
   }
  

• When a Base Class has a virtual member function, any class that inherits from the Base Class can redefine the function with exactly the same prototype i.e. only functionality can be redefined, not the interface of the function.

   class Derive : public Base
   {
      void func();
   }
  

• A Base class pointer can be used to point to Base class object as well as a Derived class object.

• When the virtual function is called by using a Base class pointer, the compiler decides at run-time which version of the function - i.e. the Base class version or the overridden Derived class version - is to be called. This is called Runtime Polymorphism.

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables
request.POST['section'] # => [39]
request.POST['MAINS'] # => [137]

# HTTP GET variables
request.GET['section'] # => [39]
request.GET['MAINS'] # => [137]

# HTTP POST and HTTP GET variables (Deprecated since Django 1.7)
request.REQUEST['section'] # => [39]
request.REQUEST['MAINS'] # => [137]

You mean you want 1b and 1b to be side by side?

 <div class="col-lg-6 col-md-6 col-12 child1">
      <div class="col-6 child1a">Child content 1a</div>
      <div class="col-6 child1b">Child content 1b</div>
 </div>

Define a class for key definition in your group.

class KeyObj {

    ArrayList<Object> keys;

    public KeyObj( Object... objs ) {
        keys = new ArrayList<Object>();

        for (int i = 0; i < objs.length; i++) {
            keys.add( objs[i] );
        }
    }

    // Add appropriate isEqual() ... you IDE should generate this

}

Now in your code,

peopleByManyParams = people
            .collect(Collectors.groupingBy(p -> new KeyObj( p.age, p.other1, p.other2 ), Collectors.mapping((Person p) -> p, toList())));

$pageURL = (@$_SERVER["HTTPS"] == "on") ? "https://" : "http://";
if ($_SERVER["SERVER_PORT"] != "80")
{
    $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
} 
else 
{
    $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
}
return $pageURL;

There are two ways to resolve this error:

1. Include /etc/apache2/httpd.conf

   Add the above line in file /etc/apache2/apache2.conf

2. Add this line at the end of the file /etc/apache2/apache2.conf:

   ServerName localhost

I get this error when my project .net framework version does not match the framework version of the DLL I am linking to. In my case, I was getting:

"The type or namespace name 'UserVoice' could not be found (are you missing a using directive or an assembly reference?).

UserVoice was .Net 4.0, and my project properties were set to ".Net 4.0 Client Profile". Changing to .Net 4.0 on the project cleared the error. I hope this helps someone.

find . -depth -name '* *' \
| while IFS= read -r f ; do mv -i "$f" "$(dirname "$f")/$(basename "$f"|tr ' ' _)" ; done

failed to get it right at first, because I didn't think of directories.

OneToOneField (one-to-one) realizes, in object orientation, the notion of composition, while ForeignKey (one-to-many) relates to agregation.

Use std::stringstream. Its operator << is overloaded for all built-in types.

#include <sstream>    

std::stringstream s;
s << "(" << c1 << "," << c2 << ")";
storedCorrect[count] = s.str();

This works like you'd expect - the same way you print to the screen with std::cout. You're simply "printing" to a string instead. The internals of operator << take care of making sure there's enough space and doing any necessary conversions (e.g., double to string).

Also, if you have the Boost library available, you might consider looking into lexical_cast. The syntax looks much like the normal C++-style casts:

#include <string>
#include <boost/lexical_cast.hpp>
using namespace boost;

storedCorrect[count] = "(" + lexical_cast<std::string>(c1) +
                       "," + lexical_cast<std::string>(c2) + ")";

Under the hood, boost::lexical_cast is basically doing the same thing we did with std::stringstream. A key advantage to using the Boost library is you can go the other way (e.g., string to double) just as easily. No more messing with atof() or strtod() and raw C-style strings.

In your last block you have a comma after 'lang', followed immediately with a function. This is not valid json.

EDIT

It appears that the readme was incorrect. I had to to pass an array with the string 'twitter'.

var converter = new Showdown.converter({extensions: ['twitter']}); converter.makeHtml('whatever @meandave2020'); // output "<p>whatever <a href="http://twitter.com/meandave2020">@meandave2020</a></p>" 

I submitted a pull request to update this.

Late to the party here, but if using VSCode, a quick way to do so is to open the command palette (CTRL / CMD + SHIFT + P) and type "Pop Stash", you'll be able to retrieve your stash by name without the need to use git CLI

Below code is working on my live server as well as in my own Lapy.

Just click on the certificate in the keychain access and change the access permission if you want to avoid entering password at all, else select Always allow and it will prompt probably 4-5 times and it will be done.

For me it was a big difference when I faced this scenario (here my story:)

I needed to extract text between tags and aggregate (by concat) the text including in innner tags.

/node() did the job, while /text() made half job

/text() only returned text not included in inner tags, because inner tags are not "text nodes". You may think, "just extract text included in the inner tags in an additional xpath", however, it becomes challenging to sort the text in this original order because you dont know where to place the aggregated text from the inner tags!because you dont know where to place the aggregated text from the inner nodes.

1. When U937 cells were infected with HIV-1,
2. no induction of NF-KB factor was detected
3. , whereas high level of progeny virions was produced,
4. suggesting that this factor was not required for viral replication
5. .

Finally, /node() did exactly what I wanted, because it gets the text from inner tags too.

UPDATE will return the number of modified rows. If you use JDBC (Java), you can then check this value against 0 and, if no rows have been affected, fire INSERT instead. If you use some other programming language, maybe the number of the modified rows still can be obtained, check documentation.

This may not be as elegant but you have much simpler SQL that is more trivial to use from the calling code. Differently, if you write the ten line script in PL/PSQL, you probably should have a unit test of one or another kind just for it alone.

Close: first you call ExcelFile, but then you call the .parse method and pass it the sheet name.

>>> xl = pd.ExcelFile("dummydata.xlsx")
>>> xl.sheet_names
[u'Sheet1', u'Sheet2', u'Sheet3']
>>> df = xl.parse("Sheet1")
>>> df.head()
                  Tid  dummy1    dummy2    dummy3    dummy4    dummy5  \

What you're doing is calling the method which lives on the class itself, rather than the instance, which is okay (although not very idiomatic), but if you're doing that you would also need to pass the sheet name:

>>> parsed = pd.io.parsers.ExcelFile.parse(xl, "Sheet1")
>>> parsed.columns
Index([u'Tid', u'dummy1', u'dummy2', u'dummy3', u'dummy4', u'dummy5', u'dummy6', u'dummy7', u'dummy8', u'dummy9'], dtype=object)

All the answers are old today as of 2019 you can directly access id keyed filds in javascript simply try it

<p id="mytext"></p>
<script>mytext.innerText = 'Yes that works!'</script>

You can start reading from here jQuery.ajax()

Actually Controller Action is a public method which can be accessed through Url. So any call of an Action from an Ajax call, either MicrosoftMvcAjax or jQuery can be made. For me, jQuery is the simplest one. It got a lots of examples in the link I gave above. The typical example for an ajax call is like this.

$.ajax({
    // edit to add steve's suggestion.
    //url: "/ControllerName/ActionName",
    url: '<%= Url.Action("ActionName", "ControllerName") %>',
    success: function(data) {
         // your data could be a View or Json or what ever you returned in your action method 
         // parse your data here
         alert(data);
    }
});

            if (lbl_Code.Text == "1")
            {
                e.Row.BackColor = System.Drawing.ColorTranslator.FromHtml("#f2d9d9");
            }
        }
    }

Here's a solution using the new async/await syntax.

async function testWait() {
    alert('going to wait for 5 second');
    await wait(5000);
    alert('finally wait is over');
}

function wait(time) {
    return new Promise(resolve => {
        setTimeout(() => {
            resolve();
        }, time);
    });
}

Note: You can call function wait only in async functions

The Pro Git book mentions:

Tracking branches are local branches that have a direct relationship to a remote branch

Not exactly. The SO question "Having a hard time understanding git-fetch" includes:

There's no such concept of local tracking branches, only remote tracking branches.
So origin/master is a remote tracking branch for master in the origin repo.

But actually, once you establish an upstream branch relationship between:

• a local branch like master
• and a remote tracking branch like origin/master

Then you can consider master as a local tracking branch: It tracks the remote tracking branch origin/master which, in turn, tracks the master branch of the upstream repo origin.

Unless you have to write formulas or formatting you should consider writing out a .csv file. Infinitely simpler, infinitely faster, and Excel will do the conversion to .xls or .xlsx automatically and correctly by definition.

Note that most of XLConnect's functions are already vectorized. This means that you can read in all worksheets with one function call without having to do explicit vectorization:

require(XLConnect)
wb <- loadWorkbook(system.file("demoFiles/mtcars.xlsx", package = "XLConnect"))
lst = readWorksheet(wb, sheet = getSheets(wb))

With XLConnect 0.2-0 lst will already be a named list.

Ref and event bus both has issues when your control render is affected by v-if. So, I decided to go with a simpler method.

The idea is using an array as a queue to send methods that needs to be called to the child component. Once the component got mounted, it will process this queue. It watches the queue to execute new methods.

(Borrowing some code from Desmond Lua's answer)

Parent component code:

import ChildComponent from './components/ChildComponent'

new Vue({
  el: '#app',
  data: {
    item: {},
    childMethodsQueue: [],
  },
  template: `
  <div>
     <ChildComponent :item="item" :methods-queue="childMethodsQueue" />
     <button type="submit" @click.prevent="submit">Post</button>
  </div>
  `,
  methods: {
    submit() {
      this.childMethodsQueue.push({name: ChildComponent.methods.save.name, params: {}})
    }
  },
  components: { ChildComponent },
})

This is code for ChildComponent

<template>
 ...
</template>

<script>
export default {
  name: 'ChildComponent',
  props: {
    methodsQueue: { type: Array },
  },
  watch: {
    methodsQueue: function () {
      this.processMethodsQueue()
    },
  },
  mounted() {
    this.processMethodsQueue()
  },
  methods: {
    save() {
        console.log("Child saved...")
    },
    processMethodsQueue() {
      if (!this.methodsQueue) return
      let len = this.methodsQueue.length
      for (let i = 0; i < len; i++) {
        let method = this.methodsQueue.shift()
        this[method.name](method.params)
      }
    },
  },
}
</script>

And there is a lot of room for improvement like moving processMethodsQueue to a mixin...

You should add a .gitignore file to your project and add /.idea to it. You should add each directory / file in one line.

If you have an existing .gitignore file then you should simply add a new line to the file and put /.idea to the new line.

After that run git rm -r --cached .idea command.

If you faced an error you can run git rm -r -f --cached .idea command. After all run git add . and then git commit -m "Removed .idea directory and added a .gitignore file" and finally push the changes by running git push command.

Specify the Line Number using NR built-in variable.

awk 'NR==1{print $1}' /etc/*release

lst = [4,6,12]

[sum(lst[:i+1]) for i in xrange(len(lst))]

If you are looking for a more efficient solution (bigger lists?) a generator could be a good call (or just use numpy if you really care about perf).

def gen(lst):
    acu = 0
    for num in lst:
        yield num + acu
        acu += num

print list(gen([4, 6, 12]))

@echo off
SETLOCAL ENABLEDELAYEDEXPANSION
SET old=Vacation2010
SET new=December
for /f "tokens=*" %%f in ('dir /b *.jpg') do (
  SET newname=%%f
  SET newname=!newname:%old%=%new%!
  move "%%f" "!newname!"
)

What this does is it loops over all .jpg files in the folder where the batch file is located and replaces the Vacation2010 with December inside the filenames.

Actually AnnotationConfigApplicationContext derived from AbstractApplicationContext, which has empty postProcessBeanFactory method left for override

/**
 * Modify the application context's internal bean factory after its standard
 * initialization. All bean definitions will have been loaded, but no beans
 * will have been instantiated yet. This allows for registering special
 * BeanPostProcessors etc in certain ApplicationContext implementations.
 * @param beanFactory the bean factory used by the application context
 */
protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
}

To leverage this, Create AnnotationConfigApplicationContextProvider class which may look like following(given for Vertx instance example, you can use MyClass instead)...

public class CustomAnnotationApplicationContextProvider {
private final Vertx vertx;

public CustomAnnotationApplicationContextProvider(Vertx vertx) {
    this.vertx = vertx;
}

/**
 * Register all beans to spring bean factory
 *
 * @param beanFactory, spring bean factory to register your instances
 */
private void configureBeans(ConfigurableListableBeanFactory beanFactory) {
    beanFactory.registerSingleton("vertx", vertx);
}

/**
 * Proxy method to create {@link AnnotationConfigApplicationContext} instance with no params
 *
 * @return {@link AnnotationConfigApplicationContext} instance
 */
public AnnotationConfigApplicationContext get() {
    return new AnnotationConfigApplicationContext() {

        @Override
        protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
            super.postProcessBeanFactory(beanFactory);
            configureBeans(beanFactory);
        }
    };
}

public AnnotationConfigApplicationContext get(DefaultListableBeanFactory beanFactory) {
    return new AnnotationConfigApplicationContext(beanFactory) {

        @Override
        protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
            super.postProcessBeanFactory(beanFactory);
            configureBeans(beanFactory);
        }
    };
}

public AnnotationConfigApplicationContext get(Class<?>... annotatedClasses) {
    return new AnnotationConfigApplicationContext(annotatedClasses) {

        @Override
        protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
            super.postProcessBeanFactory(beanFactory);
            configureBeans(beanFactory);
        }
    };
}

public AnnotationConfigApplicationContext get(String... basePackages) {
    return new AnnotationConfigApplicationContext(basePackages) {

        @Override
        protected void postProcessBeanFactory(ConfigurableListableBeanFactory beanFactory) {
            super.postProcessBeanFactory(beanFactory);
            configureBeans(beanFactory);
        }
    };
}
}

While creating ApplicationContext you can create it using

Vertx vertx = ...; // either create or for vertx, it'll be passed to main verticle
ApplicationContext context = new CustomAnnotationApplicationContextProvider(vertx).get(ApplicationSpringConfig.class);

Your'e casting a boolean to boolean and expecting an integer to be displayed. It works for true but not false. Since you expect an integer:

echo (int)$bool_val;

Armin Ronacher has the correct idea. The problem is random strings can collide. I would use:

<img src="picture.jpg?1222259157.415" alt="">

Where "1222259157.415" is the current time on the server.
Generate time by Javascript with performance.now() or by Python with time.time()

The SQL Query select * from openjson ... works only with SQL version 2016 and higher. Need the SQL compatibility mode 130.

Here's a nice little Curry which lends better readability (IMHO):

The second function's signature is identical to the Array.prototype.splice method.

function mutate(s) {
    return function splice() {
        var a = s.split('');
        Array.prototype.splice.apply(a, arguments);
        return a.join('');
    };
}

mutate('101')(1, 1, '1');

I know there's already an accepted answer, but hope this is useful.

Use: Arrays.copyOf(yourArray,n);

You can add the TextField as a child to a Container that has a BoxDecoration with border property:

new Container(
  margin: const EdgeInsets.all(15.0),
  padding: const EdgeInsets.all(3.0),
  decoration: BoxDecoration(
    border: Border.all(color: Colors.blueAccent)
  ),
  child: Text("My Awesome Border"),
)

The AWS-provided tools are not useful because they are not comprehensive.

In my own quest to mitigate this problem and pull a list of all of my AWS resources, I found this: https://github.com/JohannesEbke/aws_list_all

I have not tested it yet, but it looks legit.

When app is in background as shanegao you can use

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateInactive || application.applicationState == UIApplicationStateBackground  )
    {
         //opened from a push notification when the app was on background
    }
}

But if you want to launch the application and when app is closed and you want to debug your application you can go to Edit Scheme and in left menu select Run and then in launch select Wait for executable to be launched and then you application launch when you click on push notification

Edit Scheme > Run > Wait for executable to be launched

Right click on your project -> properties -> build path. Add to your build path jar file(s) that have the javax.servlet implemenation. Ite depends on your servlet container or application server what file(s) you need to include, so search for that information.

Set the colspan attribute to 2.

...but please don't use tables for layout.

For me android:gravity="center" did the trick in the parent layout element.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/fullImageView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:adjustViewBounds="true"
        android:contentDescription="@string/fullImageView"
        android:layout_gravity="center" />

</LinearLayout>

I think your problem is inside CheckCircular, in the while condition:

Assume you have 2 nodes, first N1 and N2 point to the same node, then N1 points to the second node (last) and N2 points to null (because it's N2.next.next). In the next loop, you try to call the 'next' method on N2, but N2 is null. There you have it, NullPointerException

Yes, you can use Application.OnTime for this and then put it in a loop. It's sort of like an alarm clock where you keep hittig the snooze button for when you want it to ring again. The following updates Cell A1 every three seconds with the time.

Dim TimerActive As Boolean
Sub StartTimer()
    Start_Timer
End Sub

Private Sub Start_Timer()
    TimerActive = True
    Application.OnTime Now() + TimeValue("00:00:03"), "Timer"
End Sub

Private Sub Stop_Timer()
    TimerActive = False
End Sub

Private Sub Timer()
    If TimerActive Then
        ActiveSheet.Cells(1, 1).Value = Time
        Application.OnTime Now() + TimeValue("00:00:03"), "Timer"
    End If
End Sub

You can put the StartTimer procedure in your Auto_Open event and change what is done in the Timer proceedure (right now it is just updating the time in A1 with ActiveSheet.Cells(1, 1).Value = Time).

Note: you'll want the code (besides StartTimer) in a module, not a worksheet module. If you have it in a worksheet module, the code requires slight modification.

There is an important bit that is not mentioned in the article to which you linked and that is flex-basis. By default flex-basis is auto.

From the spec:

If the specified flex-basis is auto, the used flex basis is the value of the flex item’s main size property. (This can itself be the keyword auto, which sizes the flex item based on its contents.)

Each flex item has a flex-basis which is sort of like its initial size. Then from there, any remaining free space is distributed proportionally (based on flex-grow) among the items. With auto, that basis is the contents size (or defined size with width, etc.). As a result, items with bigger text within are being given more space overall in your example.

If you want your elements to be completely even, you can set flex-basis: 0. This will set the flex basis to 0 and then any remaining space (which will be all space since all basises are 0) will be proportionally distributed based on flex-grow.

li {
    flex-grow: 1;
    flex-basis: 0;
    /* ... */
}

This diagram from the spec does a pretty good job of illustrating the point.

And here is a working example with your fiddle.

Try the file command with -i option.

-i option Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say text/plain; charset=us-ascii rather than ASCII text.

<td><input type="radio" name="gender" value="Male" id="male" <? if($gender=='Male')
{?> checked="" <? }?>/>Male
<input type="radio" name="gender" value="Female" id="female" <? if($gender=='Female') {?> checked="" <?}?>/>Female<br/> </td>

@ClassRule
public static TestRule watchman = new TestWatcher() {
    @Override
    protected void starting( final Description description ) {
        String mN = description.getMethodName();
        if ( mN == null ) {
            mN = "setUpBeforeClass..";
        }

        final String s = StringTools.toString( "starting..JUnit-Test: %s.%s", description.getClassName(), mN );
        System.err.println( s );
    }
};

I got this problem and it turns out that JBossDevStudio 9.1 on Windows is a 32-bit program. Eclipse, and thus the JBossDevStudio, does not work with the wrong type of JVM. 64-bit eclipse needs a 64-bit JVM, 32-bit eclipse needs a 32-bit JVM. Thus configuring Eclipse to run with my installed 64-bit JDK did not work.

Installing a 32 bit JDK and running Eclipse from that solved the problem.

At least for one of my projects, an other where I had tried to configure a runtime JDK in the Eclipse project properties is still broken.

If not the AppId's business,just try to change the Team in TARGETS/identity to your company's team.

In Spring Boot 2, the easiest way is to declare in your application.properties:

spring.jackson.serialization.WRITE_ENUMS_USING_TO_STRING=true
spring.jackson.deserialization.READ_ENUMS_USING_TO_STRING=true

and define the toString() method of your enums.

Here's a very compact, but entirely correct version:

do while(isspace(*s)) s++; while(*d++ = *s++);

And here, just for my amusement, are code-golfed versions that aren't entirely correct, and get commenters upset.

If you can risk some undefined behavior, and never have empty strings, you can get rid of the body:

while(*(d+=!isspace(*s++)) = *s);

Heck, if by space you mean just space character:

while(*(d+=*s++!=' ')=*s);

Don't use that in production :)

And also ng update @angular/material will update your code and fix all imports

Did you make a mistake only in this question or in your code too?

String to byte array: "FooBar".split('').map(c => c.charCodeAt(0));

Byte array to string: [102, 111, 111, 98, 97, 114].map(c => String.fromCharCode(c)).join('');

The following snippet gives an example that shows how to get an element from a List at a specified index, and also how to use the advanced for-each loop to iterate through all elements:

    import java.util.*;

    //...

    List<String> list = new ArrayList<String>();
    list.add("Hello!");
    list.add("How are you?");

    System.out.println(list.get(0)); // prints "Hello!"

    for (String s : list) {
        System.out.println(s);
    } // prints "Hello!", "How are you?"

Note the following:

• Generic List<String> and ArrayList<String> types are used instead of raw ArrayList type.
• Variable names starts with lowercase
• list is declared as List<String>, i.e. the interface type instead of implementation type ArrayList<String>.

References

API:

• Java Collections Framework tutorial
• class ArrayList<E> implements List<E>
• interface List<E>
  • E get(int index)
    • Returns the element at the specified position in this list.

Don't use raw types

• JLS 4.8 Raw Types

  The use of raw types is allowed only as a concession to compatibility of legacy code. The use of raw types in code written after the introduction of genericity into the Java programming language is strongly discouraged. It is possible that future versions of the Java programming language will disallow the use of raw types.

• Effective Java 2nd Edition: Item 23: Don't use raw types in new code

  If you use raw types, you lose all the safety and expressiveness benefits of generics.

Prefer interfaces to implementation classes in type declarations

• Effective Java 2nd Edition: Item 52: Refer to objects by their interfaces

  [...] you should favor the use of interfaces rather than classes to refer to objects. If appropriate interface types exist, then parameters, return values, variables, and fields should all be declared using interface types.

Naming conventions

Variables: Except for variables, all instance, class, and class constants are in mixed case with a lowercase first letter.

SHOW TABLES LIKE 'TableName'

If you have ANY results, the table exists.

To use this approach in PDO:

$pdo         = new \PDO(/*...*/);
$result      = $pdo->query("SHOW TABLES LIKE 'tableName'");
$tableExists = $result !== false && $result->rowCount() > 0;

To use this approach with DEPRECATED mysql_query

$result      = mysql_query("SHOW TABLES LIKE 'tableName'");
$tableExists = mysql_num_rows($result) > 0;

My solution if your ng-grid depend of element parent(div, layout) :

directive

myapp.directive('sizeelement', function ($window) {
return{
    scope:true,
    priority: 0,
    link: function (scope, element) {
        scope.$watch(function(){return $(element).height(); }, function(newValue, oldValue) {
            scope.height=$(element).height();
        });
    }}
})

sample html

<div class="portlet  box grey" style="height: 100%" sizeelement>
    <div class="portlet-title">
        <h4><i class="icon-list"></i>Articles</h4>
    </div>
    <div class="portlet-body" style="height:{{height-34}}px">
        <div class="gridStyle" ng-grid="gridOrderLine" ="min-height: 250px;"></div>
    </div>
</div>

height-34 : 34 is fix height of my title div, you can fix other height.

It is easy directive but it work fine.

You seem to look for the input attribute value, "the initial value of the control"?

<input type="text" value="Morlodenhof 7" />

You can use android:stopWithTask="false"in manifest as bellow, This means even if user kills app by removing it from tasklist, your service won't stop.

1. Generalized Substring

To generalise the question and the answer of gniourf_gniourf (as this is what I was searching for), if you want to cut a range of characters from, say, 7th from the end to 3rd from the end, you can use this syntax:

${string: -7:4}

Where 4 is the length of course (7-3).

2. Alternative using cut

In addition, while the solution of gniourf_gniourf is obviously the best and neatest, I just wanted to add an alternative solution using cut:

echo $string | cut -c $((${#string}-2))-

Here, ${#string} is the length of the string, and the "-" means cut to the end.

3. Alternative using awk

This solution instead uses the substring function of awk to select a substring which has the syntax substr(string, start, length) going to the end if the length is omitted. length($string)-2) thus picks up the last three characters.

echo $string | awk '{print substr($1,length($1)-2) }'

It's a rectangle that prevents oval shape background to get circular.
Making view a square will fix everything.

I found this solution to be clean and working for varying textsize and text length.

public class EqualWidthHeightTextView extends TextView {

    public EqualWidthHeightTextView(Context context) {
        super(context);
    }

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

    public EqualWidthHeightTextView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);

        int r = Math.max(getMeasuredWidth(),getMeasuredHeight());
        setMeasuredDimension(r, r);

    }
}

If you transferred these files through disk or other means, it is likely they were not saved properly.

You're checking the wrong method. Moq requires that you Setup (and then optionally Verify) the method in the dependency class.

You should be doing something more like this:

class MyClassTest
{
    [TestMethod]
    public void MyMethodTest()
    {
        string action = "test";
        Mock<SomeClass> mockSomeClass = new Mock<SomeClass>();

        mockSomeClass.Setup(mock => mock.DoSomething());

        MyClass myClass = new MyClass(mockSomeClass.Object);
        myClass.MyMethod(action);

        // Explicitly verify each expectation...
        mockSomeClass.Verify(mock => mock.DoSomething(), Times.Once());

        // ...or verify everything.
        // mockSomeClass.VerifyAll();
    }
}

In other words, you are verifying that calling MyClass#MyMethod, your class will definitely call SomeClass#DoSomething once in that process. Note that you don't need the Times argument; I was just demonstrating its value.

Manually cast the sender to the type of your custom control, and then use it to delete or disable etc. Eg, something like this:

private void myCustomControl_Click(object sender, EventArgs e)
{
  ((MyCustomControl)sender).DoWhatever();
}

The 'sender' is just the object that was actioned (eg clicked).

The event args is subclassed for more complex controls, eg a treeview, so that you can know more details about the event, eg exactly where they clicked.

The default for matrix is to have 1 column. To explicitly have 0 columns, you need to write

matrix(, nrow = 15, ncol = 0)

A better way would be to preallocate the entire matrix and then fill it in

mat <- matrix(, nrow = 15, ncol = n.columns)
for(column in 1:n.columns){
  mat[, column] <- vector
}

Scanner scanner = new Scanner(System.in);
int employeeId, supervisorId;
String name;
System.out.println("Enter employee ID:");
employeeId = scanner.nextInt();
scanner.nextLine(); //This is needed to pick up the new line
System.out.println("Enter employee name:");
name = scanner.nextLine();
System.out.println("Enter supervisor ID:");
supervisorId = scanner.nextInt();

Calling nextInt() was a problem as it didn't pick up the new line (when you hit enter). So, calling scanner.nextLine() after that does the work.

You could try if using opendir() and readdir() in Perl is faster. For an example of those function, look here.

• float stores floating-point values, that is, values that have potential decimal places
• int only stores integral values, that is, whole numbers

So while both are 32 bits wide, their use (and representation) is quite different. You cannot store 3.141 in an integer, but you can in a float.

Dissecting them both a little further:

In an integer, all bits are used to store the number value. This is (in Java and many computers too) done in the so-called two's complement. This basically means that you can represent the values of −2³¹ to 2³¹ − 1.

In a float, those 32 bits are divided between three distinct parts: The sign bit, the exponent and the mantissa. They are laid out as follows:

S EEEEEEEE MMMMMMMMMMMMMMMMMMMMMMM

There is a single bit that determines whether the number is negative or non-negative (zero is neither positive nor negative, but has the sign bit set to zero). Then there are eight bits of an exponent and 23 bits of mantissa. To get a useful number from that, (roughly) the following calculation is performed:

M × 2^E

(There is more to it, but this should suffice for the purpose of this discussion)

The mantissa is in essence not much more than a 24-bit integer number. This gets multiplied by 2 to the power of the exponent part, which, roughly, is a number between −128 and 127.

Therefore you can accurately represent all numbers that would fit in a 24-bit integer but the numeric range is also much greater as larger exponents allow for larger values. For example, the maximum value for a float is around 3.4 × 10³⁸ whereas int only allows values up to 2.1 × 10⁹.

But that also means, since 32 bits only have 4.2 × 10⁹ different states (which are all used to represent the values int can store), that at the larger end of float's numeric range the numbers are spaced wider apart (since there cannot be more unique float numbers than there are unique int numbers). You cannot represent some numbers exactly, then. For example, the number 2 × 10¹² has a representation in float of 1,999,999,991,808. That might be close to 2,000,000,000,000 but it's not exact. Likewise, adding 1 to that number does not change it because 1 is too small to make a difference in the larger scales float is using there.

Similarly, you can also represent very small numbers (between 0 and 1) in a float but regardless of whether the numbers are very large or very small, float only has a precision of around 6 or 7 decimal digits. If you have large numbers those digits are at the start of the number (e.g. 4.51534 × 10³⁵, which is nothing more than 451534 follows by 30 zeroes – and float cannot tell anything useful about whether those 30 digits are actually zeroes or something else), for very small numbers (e.g. 3.14159 × 10⁻²⁷) they are at the far end of the number, way beyond the starting digits of 0.0000...

Use

Debug.Flush();
Debug.Close();

in case exception occurs, in catch or finally block.

Edit: I personally faced this issue and I do a trick usually and it works fine. I change the type of build from 'debug' to 'release' (and 'release' to 'debug' if there is already).

Since dplyr 1.0.0, the across() function could be used:

df %>%
 group_by(Category) %>%
 summarise(across(Frequency, sum))

  Category Frequency
  <chr>        <int>
1 First           30
2 Second           5
3 Third           34

If interested in multiple variables:

df %>%
 group_by(Category) %>%
 summarise(across(c(Frequency, Frequency2), sum))

  Category Frequency Frequency2
  <chr>        <int>      <int>
1 First           30         55
2 Second           5         29
3 Third           34        190

And the selection of variables using select helpers:

df %>%
 group_by(Category) %>%
 summarise(across(starts_with("Freq"), sum))

  Category Frequency Frequency2 Frequency3
  <chr>        <int>      <int>      <dbl>
1 First           30         55        110
2 Second           5         29         58
3 Third           34        190        380

Sample data:

df <- read.table(text = "Category Frequency Frequency2 Frequency3
                 1    First        10         10         20
                 2    First        15         30         60
                 3    First         5         15         30
                 4   Second         2          8         16
                 5    Third        14         70        140
                 6    Third        20        120        240
                 7   Second         3         21         42",
                 header = TRUE,
                 stringsAsFactors = FALSE)

Additional Notes

• Since MD5 and SHA1 are obsolete and insecure algorithms, this solution uses SHA256. Alternatively, you can use BCrypt or Scrypt as pointed out in comments.
• Also, consider "salting" your hashes and use proven cryptographic algorithms, as pointed out in comments.

If you are filtering by common date this will return it:

dfs = [df1, df2, df3]
checker = dfs[-1]
check = set(checker.loc[:, 0])

for df in dfs[:-1]:
    check = check.intersection(set(df.loc[:, 0]))

print(checker[checker.loc[:, 0].isin(check)])

Use the <button> tag instead. <button> labels are vertically centered by default.

First of all uninstall ionic and cordova, later set your variables envarionment JAVA_HOME, ANDROID_HOME and PATH then reinstall ionic cordova and add platform like follow:

$ sudo npm install -g ionic cordova

$ ionic platform add android

The ionic will setup gradle packages properly.

As @epascarello mentioned for W3C standard browsers, you should use:

body.addEventListener("load", init, false);

However, if you want it to work on IE<9 as well you can use:

var prefix = window.addEventListener ? "" : "on";
var eventName = window.addEventListener ? "addEventListener" : "attachEvent";
document.body[eventName](prefix + "load", init, false);

Or if you want it in a single line:

document.body[window.addEventListener ? 'addEventListener' : 'attachEvent'](
    window.addEventListener ? "load" : "onload", init, false);

Note: here I get a straight reference to the body element via the document, saving the need for the first line.

Also, if you're using jQuery, and you want to use the DOM ready event rather than when the body loads, the answer can be even shorter...

$(init);

Not sure if this is relevant to your question but it might be relevant to someone else in the future: I had a similar error. Turned out that the df was empty (had zero rows) and that is what was causing the error in my command.

An idea could be to use the optgroup. In my case found it better than the disabled approach. It's less confusing for the user than seeing the disabled option I think.

<select id="q1" v-model="selected" v-on:change="setCPost1(selected)">
  <option value="0"></option>
  <template
    v-for="(child, idx) in getLevel1"
    v-bind:value="child.id"      
  >

  <optgroup v-bind:value="child.id" :key="idx"
  :label="child.label"
  v-if="child.label_line_two"
  >
  </optgroup>

  <option v-bind:value="child.id" :key="idx"  v-if="!child.label_line_two"
  >
  {{ child.label }}  
  </option>

  <option v-bind:value="child.id" :key="idx" v-if="child.label_line_two"
  style="font-style:italic">
  {{ child.label_line_two }}
  </option>


  </template>
</select>

An external component sounds cool like Vue Select, but I wanted to stick with the native html select at the moment.

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

You can now use inputmode=“none” on up to date browsers. See:

https://developer.mozilla.org/en-US/docs/Web/HTML/Global_attributes/inputmode

Just make sure that your HTML file is encoded with UTF-8 and that your web server sends a HTTP header with that charset, then you just can write that character directly into your HTMl file.

http://www.w3.org/International/O-HTTP-charset

If you can't use UTF-8 for some reason, you can look up the codes in a unicode list such as http://en.wikipedia.org/wiki/List_of_Unicode_characters and use ꯍ where ABCD is the hexcode from that list (U+ABCD).

In newer versions of Notepad++ (currently 5.9), this option is under:

View->Show Symbol->Show All Characters

or

View->Show Symbol->Show White Space and Tab

Write editTextBackground.xml in drawable folder in resources

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke
        android:width="1dp"
        android:color="@color/borderColor" />
</shape>

don't forget to declare color in resources named borderColor.

and assign this background to the EditText in xml background attribute

<EditText
    android:id="@+id/text"
    android:background="@drawable/editTextBackground"
    />

and it'll set border to EditText.

UPDATE

You can change border of edit text without drawable by using style attribute

style="@style/Widget.AppCompat.EditText"

The simplest fix is to make the comparator function be static:

static int comparator (const Bar & first, const Bar & second);
^^^^^^

When invoking it in Count, its name will be Foo::comparator.

The way you have it now, it does not make sense to be a non-static member function because it does not use any member variables of Foo.

Another option is to make it a non-member function, especially if it makes sense that this comparator might be used by other code besides just Foo.

If your bind_ip is set to anything other than 127.0.0.1 then you'll need to add the ip explicitly even from the local machine. So simply use the same method that you're using on the remote box on the local box. At least that's what did it for me.

I followed the steps at https://www.w3schools.com/php/php_file_upload.asp and http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html to produce this solution:

In my view (I am using the MVC paradigm, but it could be your .html or .php file, or the technology that you use for your front-end):

<form action="../../photos/upload.php" method="post" enctype="multipart/form-data">
<label for="quantity">Width:</label>
  <input type="number" id="picture_width" name="picture_width" min="10" max="800" step="1" value="500">
Select image to upload:
<input type="file" name="fileToUpload" id="fileToUpload">
<input type="submit" value="Upload Image" name="submit">
</form>

My upload.php:

<?php
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['fileToUpload']['tmp_name']);
$new_height=$h*$_POST['picture_width']/$w;
/* calculate new image size with ratio */
$ratio = max($_POST['picture_width']/$w, $new_height/$h);
$h = ceil($new_height / $ratio);
$x = ($w - $_POST['picture_width'] / $ratio) / 2;
$w = ceil($_POST['picture_width'] / $ratio);
/* new file name */
//$path = 'uploads/'.$_POST['picture_width'].'x'.$new_height.'_'.basename($_FILES['fileToUpload']['name']);
$path = 'uploads/'.basename($_FILES['fileToUpload']['name']);
/* read binary data from image file */
$imgString = file_get_contents($_FILES['fileToUpload']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($_POST['picture_width'], $new_height);
imagecopyresampled($tmp, $image,
    0, 0,
    $x, 0,
    $_POST['picture_width'], $new_height,
    $w, $h);
$uploadOk = 1;
$imageFileType = strtolower(pathinfo($path,PATHINFO_EXTENSION));
// Check if image file is a actual image or fake image
if(isset($_POST["submit"])) {
    $check = getimagesize($_FILES["fileToUpload"]["tmp_name"]);
    if($check !== false) {
        //echo "File is an image - " . $check["mime"] . ".";
        $uploadOk = 1;
    } else {
        //echo "File is not an image.";
        $uploadOk = 0;
    }
}
// Check if file already exists
if (file_exists($path)) {
    echo "Sorry, file already exists.";
    $uploadOk = 0;
}
// Check file size
if ($_FILES["fileToUpload"]["size"] > 500000) {
    echo "Sorry, your file is too large.";
    $uploadOk = 0;
}
// Allow certain file formats
if($imageFileType != "jpg" && $imageFileType != "png" && $imageFileType != "jpeg"
&& $imageFileType != "gif" ) {
    echo "Sorry, only JPG, JPEG, PNG & GIF files are allowed.";
    $uploadOk = 0;
}
// Check if $uploadOk is set to 0 by an error
if ($uploadOk == 0) {
    echo "Sorry, your file was not uploaded.";
    // if everything is ok, try to upload file
} else {
    /* Save image */
    switch ($_FILES['fileToUpload']['type']) {
        case 'image/jpeg':
            imagejpeg($tmp, $path, 100);
            break;
        case 'image/png':
            imagepng($tmp, $path, 0);
            break;
        case 'image/gif':
            imagegif($tmp, $path);
            break;
        default:
            exit;
            break;
    }
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
    /* cleanup memory */
    imagedestroy($image);
    imagedestroy($tmp);
}
?>

The name of the folder where pictures are stored is called 'uploads/'. You need to have that folder previously created and that is where you will see your pictures. It works great for me.

NOTE: This is my form:

The code is uploading and resizing pictures properly. I used this link as a guide: http://www.w3bees.com/2013/03/resize-image-while-upload-using-php.html. I modified it because in that code they specify both width and height of resized pictures. In my case, I only wanted to specify width. The height I automatically calculated it proportionally, just keeping proper picture proportions. Everything works perfectly. I hope this helps.

There are two ways to find it:

One way is to open Finder>Applications>XAMPP(FolderNotTheInstaller)>htdocs

Another way is cmd+space and searches for manager-osx,

go to Welcome and click the Open Application Folder.

Set the ValueMember/DisplayMember properties to the name of the properties of your Language objects.

class Language
{
    string text;
    string value;

    public string Text
    {
        get 
        {
            return text;
        }
    }

    public string Value
    {
        get
        {
            return value;
        }
    }

    public Language(string text, string value)
    {
        this.text = text;
        this.value = value;
    }
}

...

combo.DisplayMember= "Text";
combo.ValueMember = "Value";
combo.Items.Add(new Language("English", "en"));

TL;DR: Follow Go conventions! (lesson learned the hard way), check for old go versions and remove them. Install latest.

For me the solution was different. I worked on a shared Linux server and after verifying my GOPATH and other environment variables several times it still didn't work. I encountered several errors including 'Cannot find package' and 'unrecognized import path'. After trying to reinstall with this solution by the instructions on golang.org (including the uninstall part) still encountered problems.

Took me some time to realize that there's still an old version that hasn't been uninstalled (running go version then which go again... DAHH) which got me to this question and finally solved.

You can't change the type of an existing property.

You can add a property:

interface A {
    newProperty: any;
}

But changing a type of existing one:

interface A {
    property: any;
}

Results in an error:

Subsequent variable declarations must have the same type. Variable 'property' must be of type 'number', but here has type 'any'

You can of course have your own interface which extends an existing one. In that case, you can override a type only to a compatible type, for example:

interface A {
    x: string | number;
}

interface B extends A {
    x: number;
}

By the way, you probably should avoid using Object as a type, instead use the type any.

In the docs for the any type it states:

The any type is a powerful way to work with existing JavaScript, allowing you to gradually opt-in and opt-out of type-checking during compilation. You might expect Object to play a similar role, as it does in other languages. But variables of type Object only allow you to assign any value to them - you can’t call arbitrary methods on them, even ones that actually exist:

let notSure: any = 4;
notSure.ifItExists(); // okay, ifItExists might exist at runtime
notSure.toFixed(); // okay, toFixed exists (but the compiler doesn't check)

let prettySure: Object = 4;
prettySure.toFixed(); // Error: Property 'toFixed' doesn't exist on type 'Object'.

Actually I would advocate .profile if you need it to work from scripts, and in particular, scripts run by /bin/sh instead of Bash. If this is just for your own private interactive use, .bashrc is fine, though.

To get the fragment instance in a class that extends FragmentActivity:

MyclassFragment instanceFragment=
    (MyclassFragment)getSupportFragmentManager().findFragmentById(R.id.idFragment);

To get the fragment instance in a class that extends Fragment:

MyclassFragment instanceFragment =  
    (MyclassFragment)getFragmentManager().findFragmentById(R.id.idFragment);

To get a .class file you have to compile the .java file.

The command for this is javac. The manual for this is found here (Windows)

In short:

javac File.java

Hope this code helps for creating Thumbnail for JPG, PNG & GIF formats.

    $sourceWidth =60;
    $sourceHeight = 60;
    $what = getimagesize($file);
    $file_name = basename($file);/* Name of the Image File*/
    $ext   = pathinfo($file_name, PATHINFO_EXTENSION);

    /* Adding image name _thumb for thumbnail image */
    $file_name = basename($file_name, ".$ext") . '_thumb.' . $ext;

    switch(strtolower($what['mime']))
    {
        case 'image/png':
            $img = imagecreatefrompng($file);
            $new = imagecreatetruecolor($what[0],$what[1]);
            imagecopy($new,$img,0,0,0,0,$what[0],$what[1]);
            header('Content-Type: image/png');

Have you converted your data from string to JavaScript object?

You can do it with data = eval('(' + string_data + ')'); or, which is safer, data = JSON.parse(string_data); but later will only works in FF 3.5 or if you include json2.js

jQuery since 1.4.1 also have function for that, $.parseJSON().

But actually, $.getJSON() should give you already parsed json object, so you should just check everything thoroughly, there is little mistake buried somewhere, like you might have forgotten to quote something in json, or one of the brackets is missing.

Strictly speaking, Iterable does not have size. Think data structure like a cycle.

And think about following Iterable instance, No size:

    new Iterable(){

        @Override public Iterator iterator() {
            return new Iterator(){

                @Override
                public boolean hasNext() {
                    return isExternalSystemAvailble();
                }

                @Override
                public Object next() {
                    return fetchDataFromExternalSystem();
                }};
        }};

You can provide padding to an input like this:

HTML:

<input type=text id=firstname />

CSS:

input {
    width: 250px;
    padding: 5px;
}

however I would also add:

input {
    width: 250px;
    padding: 5px;
    -webkit-box-sizing: border-box; /* Safari/Chrome, other WebKit */
    -moz-box-sizing: border-box;    /* Firefox, other Gecko */
    box-sizing: border-box;         /* Opera/IE 8+ */
}

Box sizing makes the input width stay at 250px rather than increase to 260px due to the padding.

For reference.

In bubble sort in ith iteration you have n-i-1 inner iterations (n^2)/2 total, but in insertion sort you have maximum i iterations on i'th step, but i/2 on average, as you can stop inner loop earlier, after you found correct position for the current element. So you have (sum from 0 to n) / 2 which is (n^2) / 4 total;

That's why insertion sort is faster than bubble sort.

MediaRecorder API is the solution you are looking for,

Firefox has been supporting it for some time now, and the buzz is is Chrome is gonna implement it in its next release (Chrome 48), but guess you still might need to enable the experimental flag, apparently the flag won't be need from Chrome version 49, for more info check out this Chrome issue.

Meanwhile, a sample of how to do it in Firefox:

var video, reqBtn, startBtn, stopBtn, ul, stream, recorder;
video = document.getElementById('video');
reqBtn = document.getElementById('request');
startBtn = document.getElementById('start');
stopBtn = document.getElementById('stop');
ul = document.getElementById('ul');
reqBtn.onclick = requestVideo;
startBtn.onclick = startRecording;
stopBtn.onclick = stopRecording;
startBtn.disabled = true;
ul.style.display = 'none';
stopBtn.disabled = true;

function requestVideo() {
  navigator.mediaDevices.getUserMedia({
      video: true,
      audio: true
    })
    .then(stm => {
      stream = stm;
      reqBtn.style.display = 'none';
      startBtn.removeAttribute('disabled');
      video.src = URL.createObjectURL(stream);
    }).catch(e => console.error(e));
}

function startRecording() {
  recorder = new MediaRecorder(stream, {
    mimeType: 'video/mp4'
  });
  recorder.start();
  stopBtn.removeAttribute('disabled');
  startBtn.disabled = true;
}


function stopRecording() {
  recorder.ondataavailable = e => {
    ul.style.display = 'block';
    var a = document.createElement('a'),
      li = document.createElement('li');
    a.download = ['video_', (new Date() + '').slice(4, 28), '.webm'].join('');
    a.href = URL.createObjectURL(e.data);
    a.textContent = a.download;
    li.appendChild(a);
    ul.appendChild(li);
  };
  recorder.stop();
  startBtn.removeAttribute('disabled');
  stopBtn.disabled = true;
}

<div>

  <button id='request'>
    Request Camera
  </button>
  <button id='start'>
    Start Recording
  </button>
  <button id='stop'>
    Stop Recording
  </button>
  <ul id='ul'>
    Downloads List:
  </ul>

</div>
<video id='video' autoplay></video>

Is this what you are looking for ?

if (new int[] { 1, 2, 3, 4, 5 }.Contains(value))

Here I have my example which works just fine:

declare
 ex number;
begin
  select MAX(MAX_FK_ID)  + 1 into ex from TABLE;
  If ex > 0 then
    begin
            execute immediate 'DROP SEQUENCE SQ_NAME';
      exception when others then
        null;
    end;
    execute immediate 'CREATE SEQUENCE SQ_NAME INCREMENT BY 1 START WITH ' || ex || ' NOCYCLE CACHE 20 NOORDER';
  end if;
end;

try:

var url = '/Home/Index/' + e.value;
 window.location = window.location.host + url; 

That should get you where you want.

use $gte and $lte to find between date data's in mongodb

var tomorrowDate = moment(new Date()).add(1, 'days').format("YYYY-MM-DD");
db.collection.find({"plannedDeliveryDate":{ $gte: new Date(tomorrowDate +"T00:00:00.000Z"),$lte: new Date(tomorrowDate + "T23:59:59.999Z")}})

I got my answer from gitcredentials(7) Manual Page. For my case, I don't have credential-cache in my Windows installation; I use credential-store.

After I use credential-store, the username/password are stored in [user folder]/.git-credentials file. To remove the username/password, just delete the content of the file.

I would like to show you about how to color code. There is also a game to it if you would like to play it down below. Copy and paste if you would like and make sure to have a good day everyone! Also, this is for Python 3, not 2. ( Game )

   # The Color Game!
# Thank you for playing this game.
# Hope you enjoy and please do not copy it. Thank you!

#

import colorama
from colorama import Fore
score = 0

def Check_Answer(answer):
    if (answer == "no"):
        print('correct')
        return True
    else:
        print('wrong')

answer = input((Fore.RED + "This is green."))
if Check_Answer(answer) == True:
    score = score + 1
else:
    pass

answer = input((Fore.BLACK + "This is red."))
if Check_Answer(answer) == True:
    score = score + 1
else:
    pass

answer = input((Fore.BLUE + "This is black."))

if Check_Answer(answer) == True:
    score = score + 1
else:
    pass

print('Your Score is ', score)

Now for the color coding. It also comes with a list of colors YOU can try.

# Here is how to color code in Python 3!
# Some featured color codes are : RED, BLUE, GREEN, YELLOW, OR WHITE. I don't think purple or pink are not out yet.
# Here is how to do it. (Example is down below!)

import colorama
from colorama import Fore
print(Fore.RED + "This is red..")

In the version 3.2.4 of the XAMPP Control Panel, there is button that can open a command line prompt (red rectangle in the next figure)

After pressing the button, you will see the command prompt window.

From this window you can navigate through the different folders and start the different services available.

The way to do this in .NET Core is (at the time of writing) as follows:

public async Task<IActionResult> YourAction(YourModel model)
{
    if (ModelState.IsValid)
    {
        return StatusCode(200);
    }

    return StatusCode(400);
}

The StatusCode method returns a type of StatusCodeResult which implements IActionResult and can thus be used as a return type of your action.

As a refactor, you could improve readability by using a cast of the HTTP status codes enum like:

return StatusCode((int)HttpStatusCode.OK);

Furthermore, you could also use some of the built in result types. For example:

return Ok(); // returns a 200
return BadRequest(ModelState); // returns a 400 with the ModelState as JSON

Ref. StatusCodeResult - https://docs.microsoft.com/en-us/dotnet/api/microsoft.aspnetcore.mvc.statuscoderesult?view=aspnetcore-2.1

Using non-lambda, query-syntax LINQ, you can do this:

var movies = from row in _db.Movies 
             orderby row.Category, row.Name
             select row;

[EDIT to address comment] To control the sort order, use the keywords ascending (which is the default and therefore not particularly useful) or descending, like so:

var movies = from row in _db.Movies 
             orderby row.Category descending, row.Name
             select row;

Freddy's answer helped me a lot to get this working. For the sake of completeness here's how you could implement hashing of the token:

private string ComputeHash(Guid input)
{
    byte[] source = input.ToByteArray();

    var encoder = new SHA256Managed();
    byte[] encoded = encoder.ComputeHash(source);

    return Convert.ToBase64String(encoded);
}

In CreateAsync:

var guid = Guid.NewGuid();
...
_refreshTokens.TryAdd(ComputeHash(guid), refreshTokenTicket);
context.SetToken(guid.ToString());

ReceiveAsync:

public async Task ReceiveAsync(AuthenticationTokenReceiveContext context)
{
    Guid token;

    if (Guid.TryParse(context.Token, out token))
    {
        AuthenticationTicket ticket;

        if (_refreshTokens.TryRemove(ComputeHash(token), out ticket))
        {
            context.SetTicket(ticket);
        }
    }
}

You can extend a class using ApplicationRunner , override the run() method and add the code there.

import org.springframework.boot.ApplicationRunner;

@Component
public class ServerInitializer implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments applicationArguments) throws Exception {

        //code goes here

    }
}

You can use printenv VARIABLE instead of /bin/bash -c 'echo $VARIABLE. It's much simpler and it does not perform substitution:

docker exec container printenv VARIABLE

If you are using SQL Server Management Studio (SSMS), instead of running a query (which in my case returned duplicate rows) you can run a standard report. 

1. Right click on the database
2. Navigate to Reports > Standard Reports > Disk Usage By Table

Note: The database compatibility level must be set to 90 or above for this to work correctly. See http://msdn.microsoft.com/en-gb/library/bb510680.aspx

public class aiubMain {
public static void main(String args[]) throws MalformedURLException{
    //home frame = new home();
    java.net.URL imgUrl2 = home.class.getResource("Campus.gif");

Icon icon = new ImageIcon(imgUrl2);
JLabel label = new JLabel(icon);

JFrame f = new JFrame("Animation");
f.getContentPane().add(label);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
f.setLocationRelativeTo(null);
f.setVisible(true);
}
}

I don't believe jQuery will just naturally do a JSONP request when given a URL like that. It will, however, do a JSONP request when you tell it what argument to use for a callback:

$.get("http://metaward.com/import/http://metaward.com/u/ptarjan?jsoncallback=?", function(data) {
     alert(data);
});

It's entirely up to the receiving script to make use of that argument (which doesn't have to be called "jsoncallback"), so in this case the function will never be called. But, since you stated you just want the script at metaward.com to execute, that would make it.

As Tim Potter pointed out, setting proxy in dockerfile is horrible. When building the image, you add proxy for your corporate network but you may be deploying in cloud or a DMZ where there is no need for proxy or the proxy server is different.

Also, you cannot share your image with others outside your corporate n/w.

You can wrap it in your own function:

function isNullAndUndef(variable) {

    return (variable !== null && variable !== undefined);
}

You should really post:

1. The complete source code of your example
2. The actual result of it, not a summary

Here is my code, which works:

import socket, sys

def alert(msg):
    print >>sys.stderr, msg
    sys.exit(1)

(family, socktype, proto, garbage, address) = \
         socket.getaddrinfo("::1", "http")[0] # Use only the first tuple
s = socket.socket(family, socktype, proto)

try:
    s.connect(address) 
except Exception, e:
    alert("Something's wrong with %s. Exception type is %s" % (address, e))

When the server listens, I get nothing (this is normal), when it doesn't, I get the expected message:

Something's wrong with ('::1', 80, 0, 0). Exception type is (111, 'Connection refused')

The length of an array is available as

int l = array.length;

The size of a List is availabe as

int s = list.size();

keeps things simple just add app:tabMode="scrollable" and android:layout_gravity= "bottom"

just like this

<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
app:tabMode="scrollable"
app:tabIndicatorColor="@color/colorAccent" />

In my case I needed to do this because I had passed a method to the thread I was waiting for and that caused the lock becuase the metod was run on the GUI thread and the thread code called that method sometimes.

Task<string> myTask = Task.Run(() => {
    // Your code or method call
    return "Maybe you want to return other datatype, then just change it.";
});
// Some other code maybe...
while (true)
{
    myTask.Wait(10);
    Application.DoEvents();
    if (myTask.IsCompleted) break;
}

I just have the same problem. I have a nav posited pixed and i want the angkor to start under the nav. The solution of window.addEventListener... not work for me because i set my page to be scroll-behavior:smooth so it set the offset instead scroll to the angkor. the setTimeout() work if the time is anough for scroll to the end but it still not looking good. so my solution was to add a posited absolute div in the angkor, with height:[the height of the nav] and bottom:100%. in this case this div ended in the top of the angkor element, and start at the position where you what the angkor to scroll to. now all what i do is set the angkor link to this absolute div and the wor done :)

You can use the finish command.

finish: Continue running until just after function in the selected stack frame returns. Print the returned value (if any). This command can be abbreviated as fin.

(See 5.2 Continuing and Stepping.)

You cannot compare date-strings. It is good habit to use PHP's DateTime object instead:

$paymentDate = new DateTime(); // Today
echo $paymentDate->format('d/m/Y'); // echos today! 
$contractDateBegin = new DateTime('2001-01-01');
$contractDateEnd  = new DateTime('2015-01-01');

if (
  $paymentDate->getTimestamp() > $contractDateBegin->getTimestamp() && 
  $paymentDate->getTimestamp() < $contractDateEnd->getTimestamp()){
  echo "is between";
}else{
   echo "NO GO!";  
}

Remove Get Parameters From Current Page

<?php
$url_dir=$_SERVER['REQUEST_URI']; 

$url_dir_no_get_param= explode("?",$url_dir)[0];

echo $_SERVER['HTTP_HOST'].$url_dir_no_get_param;

This may not be as slick as a one-liner, but I use it to perform date manipulation mainly for reports:

DECLARE @Date datetime
SET @Date = GETDATE()

-- Set all time components to zero
SET @Date = DATEADD(ms, -DATEPART(ms, @Date), @Date) -- milliseconds = 0
SET @Date = DATEADD(ss, -DATEPART(ss, @Date), @Date) -- seconds = 0
SET @Date = DATEADD(mi, -DATEPART(mi, @Date), @Date) -- minutes = 0
SET @Date = DATEADD(hh, -DATEPART(hh, @Date), @Date) -- hours = 0

-- Extra manipulation for month and year
SET @Date = DATEADD(dd, -DATEPART(dd, @Date) + 1, @Date) -- day = 1
SET @Date = DATEADD(mm, -DATEPART(mm, @Date) + 1, @Date) -- month = 1

I use this to get hourly, daily, monthly, and yearly dates used for reporting and performance indicators, etc.

if not orgs:
    # Do this...
else:
    # Do that...

You can only use date in input type="date" as in format YYYY-MM-DD

I have implemented helper as formatDate in NODE.js express-handlebars, don't need to be worry ... just use format as described in first line.

e.g:

< input type="date" id="date" name="date" class="form-control" value="{{formatDate invoice.date 'YYYY-MM-DD'}}" />

You can do this with GNU grep's perl mode:

echo "12 BBQ ,45 rofl, 89 lol"|grep -P '\d+ (?=rofl)' -o

-P means Perl-style, and -o means match only.

The terms "background page", "popup", "content script" are still confusing you; I strongly suggest a more in-depth look at the Google Chrome Extensions Documentation.

Regarding your question if content scripts or background pages are the way to go:

Content scripts: Definitely
Content scripts are the only component of an extension that has access to the web-page's DOM.

Background page / Popup: Maybe (probably max. 1 of the two)
You may need to have the content script pass the DOM content to either a background page or the popup for further processing.

Let me repeat that I strongly recommend a more careful study of the available documentation!
That said, here is a sample extension that retrieves the DOM content on StackOverflow pages and sends it to the background page, which in turn prints it in the console:

background.js:

// Regex-pattern to check URLs against. 
// It matches URLs like: http[s]://[...]stackoverflow.com[...]
var urlRegex = /^https?:\/\/(?:[^./?#]+\.)?stackoverflow\.com/;

// A function to use as callback
function doStuffWithDom(domContent) {
    console.log('I received the following DOM content:\n' + domContent);
}

// When the browser-action button is clicked...
chrome.browserAction.onClicked.addListener(function (tab) {
    // ...check the URL of the active tab against our pattern and...
    if (urlRegex.test(tab.url)) {
        // ...if it matches, send a message specifying a callback too
        chrome.tabs.sendMessage(tab.id, {text: 'report_back'}, doStuffWithDom);
    }
});

content.js:

// Listen for messages
chrome.runtime.onMessage.addListener(function (msg, sender, sendResponse) {
    // If the received message has the expected format...
    if (msg.text === 'report_back') {
        // Call the specified callback, passing
        // the web-page's DOM content as argument
        sendResponse(document.all[0].outerHTML);
    }
});

manifest.json:

{
  "manifest_version": 2,
  "name": "Test Extension",
  "version": "0.0",
  ...

  "background": {
    "persistent": false,
    "scripts": ["background.js"]
  },
  "content_scripts": [{
    "matches": ["*://*.stackoverflow.com/*"],
    "js": ["content.js"]
  }],
  "browser_action": {
    "default_title": "Test Extension"
  },

  "permissions": ["activeTab"]
}

Here's an example to help you out ...

fig = plt.figure(figsize=(10,5))
ax = fig.add_subplot(111)
ax.set_title('ADR vs Rating (CS:GO)')
ax.scatter(x=data[:,0],y=data[:,1],label='Data')
plt.plot(data[:,0], m*data[:,0] + b,color='red',label='Our Fitting 
Line')
ax.set_xlabel('ADR')
ax.set_ylabel('Rating')
ax.legend(loc='best')
plt.show()

In AngularJS2 I found a new way, maybe is just the same thing but in this new version :

import {Router, RouteConfig, ROUTER_DIRECTIVES, Location} from 'angular2/router'; 

(...)

constructor(private _router: Router, private _location: Location) {}

onSubmit() {
    (...)
    self._location.back();
}

After my function, I can see that my application is going to the previous page usgin location from angular2/router.

https://angular.io/docs/ts/latest/api/common/index/Location-class.html

I don't think there is another way other than assigning value to that particular index of that array.

Array in JSON are indexed array only, so the structure you're trying to get is not valid Json/Javascript.

PHP Associatives array are objects in JSON, so unless you don't need the index, you can't do such conversions.

If you want to get such structure you can do:

$indexedOnly = array();

foreach ($associative as $row) {
    $indexedOnly[] = array_values($row);
}

json_encode($indexedOnly);

Will returns something like:

[
     [0, "name1", "n1"],
     [1, "name2", "n2"],
]

Add a little Color to your Console Text

  HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
  // you can loop k higher to see more color choices
  for(int k = 1; k < 255; k++)
  {
    // pick the colorattribute k you want
    SetConsoleTextAttribute(hConsole, k);
    cout << k << " I want to be nice today!" << endl;
  }

Character Attributes Here is how the "k" value be interpreted.
