I had the same problem while I was testing a project and it turned that running Fiddler was the cause for this error..!!

If you are using Fiddler to intercept the http request, shut it down ...

This is one of the many causes for such error.

To fix Fiddler you may need to Reset Fiddler Https Certificates.

You can also push markers into an array. See code example, this works for me:

/*create array:*/
var marker = new Array();

/*Some Coordinates (here simulating somehow json string)*/
var items = [{"lat":"51.000","lon":"13.000"},{"lat":"52.000","lon":"13.010"},{"lat":"52.000","lon":"13.020"}];

/*pushing items into array each by each and then add markers*/
function itemWrap() {
for(i=0;i<items.length;i++){
    var LamMarker = new L.marker([items[i].lat, items[i].lon]);
    marker.push(LamMarker);
    map.addLayer(marker[i]);
    }
}

/*Going through these marker-items again removing them*/
function markerDelAgain() {
for(i=0;i<marker.length;i++) {
    map.removeLayer(marker[i]);
    }  
}

This is my working solution:

select tabname as table_name
from syscat.tables
where tabschema = 'schema_name' -- put schema name here
      and type = 'T'
order by tabname

This function will produce required table as list of tuples.

def get_documents_by_user_email(email):
    query = session.query(
       User.email, 
       User.name, 
       Document.name, 
       DocumentsPermissions.readAllowed, 
       DocumentsPermissions.writeAllowed,
    )
    join_query = query.join(Document).join(DocumentsPermissions)

    return join_query.filter(User.email == email).all()

user_docs = get_documents_by_user_email(email)

Two comments:

• Use and and or for logical operations in Python.
• Use 4 spaces to indent instead of 2. You will thank yourself later because your code will look pretty much the same as everyone else's code. See PEP 8 for more details.

This can help. It has code examples too:

http://csv-mapper.rubyforge.org/

Or for a rake task for doing the same:

http://erikonrails.snowedin.net/?p=212

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

Try

function RadionButtonSelectedValueSet(name, SelectdValue) {
    $('input[name="' + name+ '"][value="' + SelectdValue + '"]').prop('checked', true);
}

also call the method on dom ready

<script type="text/javascript">
jQuery(function(){
    RadionButtonSelectedValueSet('RBLExperienceApplicable', '1');
})
</script>

I suggest to use

for string only state values

export default class Home extends React.Component<{}, { [key: string]: string }> { }

for string key and any type of state values

export default class Home extends React.Component<{}, { [key: string]: any}> { }

for any key / any values

export default class Home extends React.Component<{}, { [key: any]: any}> {}

To show a problem is NP complete, you need to:

Show it is in NP

In other words, given some information C, you can create a polynomial time algorithm V that will verify for every possible input X whether X is in your domain or not.

Example

Prove that the problem of vertex covers (that is, for some graph G, does it have a vertex cover set of size k such that every edge in G has at least one vertex in the cover set?) is in NP:

• our input X is some graph G and some number k (this is from the problem definition)

• Take our information C to be "any possible subset of vertices in graph G of size k"

• Then we can write an algorithm V that, given G, k and C, will return whether that set of vertices is a vertex cover for G or not, in polynomial time.

Then for every graph G, if there exists some "possible subset of vertices in G of size k" which is a vertex cover, then G is in NP.

Note that we do not need to find C in polynomial time. If we could, the problem would be in `P.

Note that algorithm V should work for every G, for some C. For every input there should exist information that could help us verify whether the input is in the problem domain or not. That is, there should not be an input where the information doesn't exist.

Prove it is NP Hard

This involves getting a known NP-complete problem like SAT, the set of boolean expressions in the form:

(A or B or C) and (D or E or F) and ...

where the expression is satisfiable, that is there exists some setting for these booleans, which makes the expression true.

Then reduce the NP-complete problem to your problem in polynomial time.

That is, given some input X for SAT (or whatever NP-complete problem you are using), create some input Y for your problem, such that X is in SAT if and only if Y is in your problem. The function f : X -> Y must run in polynomial time.

In the example above, the input Y would be the graph G and the size of the vertex cover k.

For a full proof, you'd have to prove both:

• that X is in SAT => Y in your problem

• and Y in your problem => X in SAT.

marcog's answer has a link with several other NP-complete problems you could reduce to your problem.

Footnote: In step 2 (Prove it is NP-hard), reducing another NP-hard (not necessarily NP-complete) problem to the current problem will do, since NP-complete problems are a subset of NP-hard problems (that are also in NP).

In JavaScript? Just instantiate a new Date object

var now = new Date();

That will create a new Date object with the client's local time.

If you want to trigger the event as you type, use the following:

$('input[name=myInput]').on('keyup', function() { ... });

If you want to trigger the event on leaving the input field, use the following:

$('input[name=myInput]').on('change', function() { ... });

You might want to look at ConcurrentDoublyLinkedList written by Doug Lea based on Paul Martin's "A Practical Lock-Free Doubly-Linked List". It does not implement the java.util.List interface, but offers most methods you would use in a List.

According to the javadoc:

A concurrent linked-list implementation of a Deque (double-ended queue). Concurrent insertion, removal, and access operations execute safely across multiple threads. Iterators are weakly consistent, returning elements reflecting the state of the deque at some point at or since the creation of the iterator. They do not throw ConcurrentModificationException, and may proceed concurrently with other operations.

Strictly speaking, you can't get an iterator of the primitive array, because Iterator.next() can only return an Object. But through the magic of autoboxing, you can get the iterator using the Arrays.asList() method.

Iterator<Integer> it = Arrays.asList(arr).iterator();

The above answer is wrong, you can't use Arrays.asList() on a primitive array, it would return a List<int[]>. Use Guava's Ints.asList() instead.

const myMap = new Map(
    Object
        .keys(myObj)
        .map(
            key => [key, myObj[key]]
        )
)

Simply call InetAddress.getByName(String host) passing in your textual IP address.

From the javadoc: The host name can either be a machine name, such as "java.sun.com", or a textual representation of its IP address.

InetAddress javadoc

If you are talking about sed, this works:

sed -e "s/ /,/g" < a.txt

In vim, use same regex to replace:

s/ /,/g

If you just want to rename and don't mind using an external tool, then you can use rnm. The command would be:

#on current folder
rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' *

-dp -1 will make it recursive to all subdirectories.

-fo implies file only mode.

-ssf '_dbg' searches for files with _dbg in the filename.

-rs '/_dbg//' replaces _dbg with empty string.

You can run the above command with the path of the CURRENT_FOLDER too:

rnm -dp -1 -fo -ssf '_dbg' -rs '/_dbg//' /path/to/the/directory

Is there a function in the .net Math library?

No.

It's not hard to write your own though. The naive algorithm sorts the array and picks the middle (or the average of the two middle) elements. However, this algorithm is O(n log n) while its possible to solve this problem in O(n) time. You want to look at selection algorithms to get such an algorithm.

You can delete the folder itself, as well as all its contents, using shutil.rmtree:

import shutil
shutil.rmtree('/path/to/folder')

shutil.rmtree(path, ignore_errors=False, onerror=None)

Delete an entire directory tree; path must point to a directory (but not a symbolic link to a directory). If ignore_errors is true, errors resulting from failed removals will be ignored; if false or omitted, such errors are handled by calling a handler specified by onerror or, if that is omitted, they raise an exception.

maybe you forgot to add ";" after this line of code:

`quantity` INT NOT NULL)

The WHATWG HTML spec has the exact algorithm for parsing a legacy color value: https://html.spec.whatwg.org/multipage/infrastructure.html#rules-for-parsing-a-legacy-colour-value.

The code Netscape Classic used for parsing color strings is open source: https://dxr.mozilla.org/classic/source/lib/layout/layimage.c#155.

For example, notice that each character is parsed as a hex digit and then is shifted into a 32-bit integer without checking for overflow. Only eight hex digits fit into a 32-bit integer, which is why only the last 8 characters are considered. After parsing the hex digits into 32-bit integers, they are then truncated into 8-bit integers by dividing them by 16 until they fit into 8-bit, which is why leading zeros are ignored.

Update: This code does not exactly match what is defined in the spec, but the only difference there is a few lines of code. I think it is these lines that was added (in Netscape 4):

if (bytes_per_val > 4)
{
    bytes_per_val = 4;
}

If you have several ruby installed, it might be sufficient just to remove one of them, on MacosX with extra ports install, remove the ports ruby installation with:

sudo port -f uninstall ruby

• Download xampp and uncomment oracle 12c extension or 11c 'extension=oci8_11g' for xampp 7.2.9
• Download instant client 32 bit and set its path
• Download instant client 32 bit SDK package and set its path
• Copy instant clients and SDK dll files to xamp\php\ext, xampp\php\ and xampp\appache\bin\
• Download php-oci of same php version of tread safe x86 then copy its files to php\ext*.dll, php version is written on top of phpinfo tab of xampp admin.
• OCI8 will appear on phpadmin page or apache admin then phpadmin tab. It means phpOCI has been installed.

tl;dr

LocalDate.of( 2018 , Month.JANUARY , 23 )
         .format( DateTimeFormatter.ofPattern( “uuuu-MM-EEE” , Locale.US )  )

java.time

The modern approach uses the java.time classes.

LocalDate ld = LocalDate.of( 2018 , Month.JANUARY , 23 ) ;

Note how we specify a Locale such as Locale.CANADA_FRENCH to determine the human language used to translate the name of the day.

DateTimeFormatter f = DateTimeFormatter.ofPattern( “uuuu-MM-EEE” , Locale.US ) ;
String output = ld.format( f ) ;

ISO 8601

By the way, you may be interested in the standard ISO 8601 week numbering scheme: yyyy-Www-d.

2018-W01-2

Week # 1 has the first Thursday of the calendar-year. Week starts on a Monday. A year has either 52 or 53 weeks. The last/first few days of a calendar-year may land in the next/previous week-based-year.

The single digit on the end is day-of-week, 1-7 for Monday-Sunday.

Add the ThreeTen-Extra library class to your project for the YearWeek class.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

One thing you can do is get rid of all those onclick attributes and do it the right way with bootstrap. You don't need to open them manually; you can specify the trigger and even subscribe to events before the modal opens so that you can do your operations and populate data in it.

I am just going to show as a static example which you can accommodate in your real world.

On each of your <tr>'s add a data attribute for id (i.e. data-id) with the corresponding id value and specify a data-target, which is a selector you specify, so that when clicked, bootstrap will select that element as modal dialog and show it. And then you need to add another attribute data-toggle=modal to make this a trigger for modal.

  <tr data-toggle="modal" data-id="1" data-target="#orderModal">
            <td>1</td>
            <td>24234234</td>
            <td>A</td>
  </tr>
  <tr data-toggle="modal" data-id="2" data-target="#orderModal">
            <td>2</td>
            <td>24234234</td>
            <td>A</td>
        </tr>
  <tr data-toggle="modal" data-id="3" data-target="#orderModal">
            <td>3</td>
            <td>24234234</td>
            <td>A</td>
  </tr>

And now in the javascript just set up the modal just once and event listen to its events so you can do your work.

$(function(){
    $('#orderModal').modal({
        keyboard: true,
        backdrop: "static",
        show:false,

    }).on('show', function(){ //subscribe to show method
          var getIdFromRow = $(event.target).closest('tr').data('id'); //get the id from tr
        //make your ajax call populate items or what even you need
        $(this).find('#orderDetails').html($('<b> Order Id selected: ' + getIdFromRow  + '</b>'))
    });
});

Demo

Do not use inline click attributes any more. Use event bindings instead with vanilla js or using jquery.

For whoever is still looking for a totally transparent panel, I found a nice solution in this blog by William Smash who in turn has taken it from Tobias Hertkorn on his T# blog. I thought its worth posting it as an answer here.

C# code:

public class TransparentPanel : Panel
{
    protected override CreateParams CreateParams 
    {            
        get {
            CreateParams cp =  base.CreateParams;
            cp.ExStyle |= 0x00000020; // WS_EX_TRANSPARENT
            return cp;
            }
    }
    protected override void OnPaintBackground(PaintEventArgs e) 
    {
        //base.OnPaintBackground(e);
    }
}

VB.Net code:

Public Class TransparentPanel
Inherits Panel
    Protected Overrides ReadOnly Property CreateParams() As System.Windows.Forms.CreateParams
        Get
            Dim cp As CreateParams = MyBase.CreateParams
            cp.ExStyle = cp.ExStyle Or &H20 ''#WS_EX_TRANSPARENT
            Return cp
        End Get
    End Property
    Protected Overrides Sub OnPaintBackground(ByVal e As System.Windows.Forms.PaintEventArgs)
    ''#MyBase.OnPaintBackground(e)
    End Sub
End Class

Dennis answer is correct. However I would like to explain the solution in a bit more detailed way (for Windows User):

1. Go into your Start Menu and type regedit into the search field.
2. Navigate to path HKEY_LOCAL_MACHINE\Software\JavaSoft (Windows 10 seems to now have this here: HKEY_LOCAL_MACHINE\Software\WOW6432Node\JavaSoft)
3. Right click on the JavaSoft folder and click on New -> Key
4. Name the new Key Prefs and everything should work.

Alternatively, save and execute a *.reg file with the following content:

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs]

GROUP BY can be selected from Total row in query design view in MS Access.
If Total row not shown in design view (as in my case). You can go to SQL View and add GROUP By fname etc. Then Total row will automatically show in design view.
You have to select as Expression in this row for calculated fields.

Use:

ImageView image = (ImageView) findViewById(R.id.image);
image.setAlpha(150); // Value: [0-255]. Where 0 is fully transparent
                     // and 255 is fully opaque. Set the value according
                     // to your choice, and you can also use seekbar to
                     // maintain the transparency.

The recommended approach in this case is to sort the data in the database, adding an ORDER BY at the end of the query that fetches the results, something like this:

SELECT temperature FROM temperatures ORDER BY temperature ASC;  -- ascending order
SELECT temperature FROM temperatures ORDER BY temperature DESC; -- descending order

If for some reason that is not an option, you can change the sorting order like this in Python:

templist = [25, 50, 100, 150, 200, 250, 300, 33]
sorted(templist, key=int)               # ascending order
> [25, 33, 50, 100, 150, 200, 250, 300]
sorted(templist, key=int, reverse=True) # descending order
> [300, 250, 200, 150, 100, 50, 33, 25]

As has been pointed in the comments, the int key (or float if values with decimals are being stored) is required for correctly sorting the data if the data received is of type string, but it'd be very strange to store temperature values as strings, if that is the case, go back and fix the problem at the root, and make sure that the temperatures being stored are numbers.

WORKER TIMEOUT means your application cannot response to the request in a defined amount of time. You can set this using gunicorn timeout settings. Some application need more time to response than another.

Another thing that may affect this is choosing the worker type

The default synchronous workers assume that your application is resource-bound in terms of CPU and network bandwidth. Generally this means that your application shouldn’t do anything that takes an undefined amount of time. An example of something that takes an undefined amount of time is a request to the internet. At some point the external network will fail in such a way that clients will pile up on your servers. So, in this sense, any web application which makes outgoing requests to APIs will benefit from an asynchronous worker.

When I got the same problem as yours (I was trying to deploy my application using Docker Swarm), I've tried to increase the timeout and using another type of worker class. But all failed.

And then I suddenly realised I was limitting my resource too low for the service inside my compose file. This is the thing slowed down the application in my case

deploy:
  replicas: 5
  resources:
    limits:
      cpus: "0.1"
      memory: 50M
  restart_policy:
    condition: on-failure

So I suggest you to check what thing slowing down your application in the first place

Instal Microsoft 2007 Access Runtime.

from https://www.microsoft.com/en-US/download/details.aspx?id=4438

If you want to do the background explicitly, you must be certain that you draw behind the current elements on the canvas.

var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
// Add behind elements.
ctx.globalCompositeOperation = 'destination-over'
// Now draw!
ctx.fillStyle = "blue";
ctx.fillRect(0, 0, canvas.width, canvas.height);

In Simple,e.printStackTrace() is not good practice,because it just prints out the stack trace to standard error. Because of this you can't really control where this output goes.

This is deprecated:

as.data.frame(my_table)

Instead use this package:

library("quanteda")
convert(my_table, to="data.frame") 

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

it will works

The answer is short: alert(arguments.callee.name);

I'd like to add a new version of flatten case (this is what i needed :)) which, according to my probes with the above jsFiddler, is slightly faster then the currently selected one. Moreover, me personally see this snippet a bit more readable, which is of course important for multi-developer projects.

function flattenObject(graph) {
    let result = {},
        item,
        key;

    function recurr(graph, path) {
        if (Array.isArray(graph)) {
            graph.forEach(function (itm, idx) {
                key = path + '[' + idx + ']';
                if (itm && typeof itm === 'object') {
                    recurr(itm, key);
                } else {
                    result[key] = itm;
                }
            });
        } else {
            Reflect.ownKeys(graph).forEach(function (p) {
                key = path + '.' + p;
                item = graph[p];
                if (item && typeof item === 'object') {
                    recurr(item, key);
                } else {
                    result[key] = item;
                }
            });
        }
    }
    recurr(graph, '');

    return result;
}

SQL injection is the attempt to issue SQL commands to a database through a website interface, to gain other information. Namely, this information is stored database information such as usernames and passwords.

First rule of securing any script or page that attaches to a database instance is Do not trust user input.

Your example is attempting to end a misquoted string in an SQL statement. To understand this, you first need to understand SQL statements. In your example of adding a ' to a paramater, your 'injection' is hoping for the following type of statement:

SELECT username,password FROM users WHERE username='$username'

By appending a ' to that statement, you could then add additional SQL paramaters or queries.: ' OR username --

SELECT username,password FROM users WHERE username='' OR username -- '$username

That is an injection (one type of; Query Reshaping). The user input becomes an injected statement into the pre-written SQL statement.

Generally there are three types of SQL injection methods:

• Query Reshaping or redirection (above)
• Error message based (No such user/password)
• Blind Injections

Read up on SQL Injection, How to test for vulnerabilities, understanding and overcoming SQL injection, and this question (and related ones) on StackOverflow about avoiding injections.

Edit:

As far as TESTING your site for SQL injection, understand it gets A LOT more complex than just 'append a symbol'. If your site is critical, and you (or your company) can afford it, hire a professional pen tester. Failing that, this great exaxmple/proof can show you some common techniques one might use to perform an injection test. There is also SQLMap which can automate some tests for SQL Injection and database take over scenarios.

Not sure if Access supports it, but in most engines (including SQL Server) this is called a correlated subquery and works fine:

SELECT  TypesAndBread.Type, TypesAndBread.TBName,
        (
        SELECT  Count(Sandwiches.[SandwichID]) As SandwichCount
        FROM    Sandwiches
        WHERE   (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
                OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
        ) As SandwichCount
FROM    TypesAndBread

This can be made more efficient by indexing Type and Bread and distributing the subqueries over the UNION:

SELECT  [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
        )
FROM    [Sandwiches Types]
UNION ALL
SELECT  [Breads].[Bread] As TBName, "Bread" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Bread = [Breads].[Bread]
        )
FROM    [Breads]

The below steps for using Android OpenCV sdk in Android Studio. This is a simplified version of this(1) SO answer.

1. Download latest OpenCV sdk for Android from OpenCV.org and decompress the zip file.
2. Import OpenCV to Android Studio, From File -> New -> Import Module, choose sdk/java folder in the unzipped opencv archive.
3. Update build.gradle under imported OpenCV module to update 4 fields to match your project build.gradle a) compileSdkVersion b) buildToolsVersion c) minSdkVersion and d) targetSdkVersion.
4. Add module dependency by Application -> Module Settings, and select the Dependencies tab. Click + icon at bottom, choose Module Dependency and select the imported OpenCV module.
   • For Android Studio v1.2.2, to access to Module Settings : in the project view, right-click the dependent module -> Open Module Settings
5. Copy libs folder under sdk/native to Android Studio under app/src/main.
6. In Android Studio, rename the copied libs directory to jniLibs and we are done.

Step (6) is since Android studio expects native libs in app/src/main/jniLibs instead of older libs folder. For those new to Android OpenCV, don't miss below steps

• include static{ System.loadLibrary("opencv_java"); } (Note: for OpenCV version 3 at this step you should instead load the library opencv_java3.)
• For step(5), if you ignore any platform libs like x86, make sure your device/emulator is not on that platform.

OpenCV written is in C/C++. Java wrappers are

1. Android OpenCV SDK - OpenCV.org maintained Android Java wrapper. I suggest this one.
2. OpenCV Java - OpenCV.org maintained auto generated desktop Java wrapper.
3. JavaCV - Popular Java wrapper maintained by independent developer(s). Not Android specific. This library might get out of sync with OpenCV newer versions.

You can also use the shorter format

From the man page:

%F     full date; same as %Y-%m-%d

Example:

#!/bin/bash
date_today=$(date +%F)
date_dir=$(date +%F -d yesterday)

Because the number can be up to 15 digits, you'll need to cast to an 64 bit (8-byte) integer. Try this:

SELECT * FROM table
WHERE myint = mytext::int8

The :: cast operator is historical but convenient. Postgres also conforms to the SQL standard syntax

myint = cast ( mytext as int8)

If you have literal text you want to compare with an int, cast the int to text:

SELECT * FROM table
WHERE myint::varchar(255) = mytext

Does your page contain these

<asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1"
Runat="Server">
</asp:content>

tags, and are all your controls inside these? You should only have the Form tags in the MasterPage.

Here are some of my understanding and suggestion:

Html element can be put in the body of html pages and html page does support multiple elements, however they can not be nested each other, you can find the detailed description from the W3C html specification:

The FORM element

http://www.w3.org/MarkUp/html3/forms.html

And as for ASP.NET web form page, it is based on a single server-side form element which contains all the controls inside it, so generally we do not recommend that we put multiple elements. However, this is still supported in ASP.NET page(master page) and I think the problem in your master page should be caused by the unsupported nested element, and multiple in the same level should be ok. e.g:

In addition, if what you want to do through multiple forms is just make our page posting to multiple pages, I think you can consider using the new feature for cross-page posting in ASP.NET 2.0. This can help us use button controls to postback to different pages without having multpile forms on the page:

DO
$do$
BEGIN
   IF EXISTS (SELECT FROM orders) THEN
      DELETE FROM orders;
   ELSE
      INSERT INTO orders VALUES (1,2,3);
   END IF;
END
$do$

There are no procedural elements in standard SQL. The IF statement is part of the default procedural language PL/pgSQL. You need to create a function or execute an ad-hoc statement with the DO command.

You need a semicolon (;) at the end of each statement in plpgsql (except for the final END).

You need END IF; at the end of the IF statement.

A sub-select must be surrounded by parentheses:

    IF (SELECT count(*) FROM orders) > 0 ...

Or:

    IF (SELECT count(*) > 0 FROM orders) ...

This is equivalent and much faster, though:

    IF EXISTS (SELECT FROM orders) ...

Alternative

The additional SELECT is not needed. This does the same, faster:

DO
$do$
BEGIN
   DELETE FROM orders;
   IF NOT FOUND THEN
      INSERT INTO orders VALUES (1,2,3);
   END IF;
END
$do$

Though unlikely, concurrent transactions writing to the same table may interfere. To be absolutely sure, write-lock the table in the same transaction before proceeding as demonstrated.

Preferred string type in C++ is string, defined in namespace std, in header <string> and you can initialize it like this for example:

#include <string>

int main()
{
   std::string str1("Some text");
   std::string str2 = "Some text";
}

More about it you can find here and here.

The error message tells the exact reason: "abstract methods cannot have a body".

They can only be defined in abstract classes and interfaces (interface methods are implicitly abstract!) and the idea is, that the subclass implements the method.

Example:

 public abstract class AbstractGreeter {
   public abstract String getHelloMessage();

   public void sayHello() {
     System.out.println(getHelloMessage());
   }
 }

 public class FrenchGreeter extends AbstractGreeter{

   // we must implement the abstract method
   @Override
   public String getHelloMessage() {
     return "bonjour";
   }
 }

Here is My Code

protected void btnExcel_Click(object sender, ImageClickEventArgs e)
    {
        if (gvDetail.Rows.Count > 0)
        {
            System.IO.StringWriter stringWrite1 = new System.IO.StringWriter();
            System.Web.UI.HtmlTextWriter htmlWrite1 = new HtmlTextWriter(stringWrite1);
            gvDetail.RenderControl(htmlWrite1);

            gvDetail.AllowPaging = false;
            Search();
            sh.ExportToExcel(gvDetail, "Report");
        }
    }

    public override void VerifyRenderingInServerForm(Control control)
    {
        /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
           server control at run time. */
    }

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".

Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".

Java references always point to an object. The object has a header that amongst other things identifies the concrete type (so casts can fail with ClassCastException). For arrays, the start of the object also includes the length, the data then follows immediately after in memory (technically an implementation is free to do what it pleases, but it would be daft to do anything else). So, you can;t have a reference that points somewhere into an array.

In C pointers point anywhere and to anything, and you can point to the middle of an array. But you can't safely cast or find out how long the array is. In D the pointer contains an offset into the memory block and length (or equivalently a pointer to the end, I can't remember what the implementation actually does). This allows D to slice arrays. In C++ you would have two iterators pointing to the start and end, but C++ is a bit odd like that.

So getting back to Java, no you can't. As mentioned, NIO ByteBuffer allows you to wrap an array and then slice it, but gives an awkward interface. You can of course copy, which is probably very much faster than you would think. You could introduce your own String-like abstraction that allows you to slice an array (the current Sun implementation of String has a char[] reference plus a start offset and length, higher performance implementation just have the char[]). byte[] is low level, but any class-based abstraction you put on that is going to make an awful mess of the syntax, until JDK7 (perhaps).

You can use calc to position element relative to center. For example if you want to position element 200px right from the center .. you can do this :

#your_element{
    position:absolute;
    left: calc(50% + 200px);
}

Dont forget this

When you use signs + and - you must have one blank space between sign and number, but when you use signs * and / there is no need for blank space.

On my system (Windows 8.1), Sublime 2 shows default font "Consolas". You can find yours by following this procedure:

1. go to View menu and select Show Console
2. Then enter this command: view.settings().get('font_face')

You will find your default font.

Here is a little something I cooked up today. Seems to work for me. Basically you override the Add method in your base namespace to do a check and then call the base's Add method in order to actually add it. Hope this works for you

                base.Add(key, value);
            }

Try out below drawable file. Create file named "circle" in your res/drawable folder and copy below code:

   <?xml version="1.0" encoding="utf-8"?>

    android:shape="oval" >

    <solid android:color="#FFFFFF" />

Apply it in your TextView as below:

        android:id="@+id/tvSummary1"
        android:layout_width="270dp"
        android:layout_height="60dp"

        android:gravity="left|center_vertical"
        android:background="@drawable/round_bg">

    </TextView>

This is the problem

double a[] = null;

Since a is null, NullPointerException will arise every time you use it until you initialize it. So this:

a[i] = var;

will fail.

A possible solution would be initialize it when declaring it:

double a[] = new double[PUT_A_LENGTH_HERE]; //seems like this constant should be 7

IMO more important than solving this exception, is the fact that you should learn to read the stacktrace and understand what it says, so you could detect the problems and solve it.

java.lang.NullPointerException

This exception means there's a variable with null value being used. How to solve? Just make sure the variable is not null before being used.

at twoten.TwoTenB.(TwoTenB.java:29)

This line has two parts:

• First, shows the class and method where the error was thrown. In this case, it was at <init> method in class TwoTenB declared in package twoten. When you encounter an error message with SomeClassName.<init>, means the error was thrown while creating a new instance of the class e.g. executing the constructor (in this case that seems to be the problem).
• Secondly, shows the file and line number location where the error is thrown, which is between parenthesis. This way is easier to spot where the error arose. So you have to look into file TwoTenB.java, line number 29. This seems to be a[i] = var;.

From this line, other lines will be similar to tell you where the error arose. So when reading this:

at javapractice.JavaPractice.main(JavaPractice.java:32)

It means that you were trying to instantiate a TwoTenB object reference inside the main method of your class JavaPractice declared in javapractice package.

id and class are two Global / Standard HTML attribute (The global attributes below can be used on any HTML element.)

class Specifies one or more classnames for an element (refers to a class in a style sheet)

id Specifies a unique id for an element

The id attributes gives an element document-wide unique identifier where the class attribute provides a way of classifying similar elements.

The id attribute value must be unique across the HTML page where class attribute can be reused where ever you want to apply the same properties

There are many questions about REST auth patterns here on SO. These are the most relevant for your question:

• Securing my Node.js app's REST API?
• RESTful Authentication

Basically you need to choose between using API keys (least secure as the key may be discovered by an unauthorized user), an app key and token combo (medium), or a full OAuth implementation (most secure).

$("element").on("event1 event2 event..n", function() {
   //execution
});

This tutorial is about handling multiple events.

As David and Remou pointed out, vbCrLf if you want a carriage-return-linefeed combination. Otherwise, Chr(13) and Chr(10) (although some VB-derivatives have vbCr and vbLf; VBScript may well have those, worth checking before using Chr).

Here's a complete example of an HTTP GET request with parameters using angular.js in ASP.NET MVC:

CONTROLLER:

public class AngularController : Controller
{
    public JsonResult GetFullName(string name, string surname)
    {
        System.Diagnostics.Debugger.Break();
        return Json(new { fullName = String.Format("{0} {1}",name,surname) }, JsonRequestBehavior.AllowGet);
    }
}

VIEW:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.min.js"></script>
<script type="text/javascript">
    var myApp = angular.module("app", []);

    myApp.controller('controller', function ($scope, $http) {

        $scope.GetFullName = function (employee) {

            //The url is as follows - ControllerName/ActionName?name=nameValue&surname=surnameValue

            $http.get("/Angular/GetFullName?name=" + $scope.name + "&surname=" + $scope.surname).
            success(function (data, status, headers, config) {
                alert('Your full name is - ' + data.fullName);
            }).
            error(function (data, status, headers, config) {
                alert("An error occurred during the AJAX request");
            });

        }
    });

</script>

<div ng-app="app" ng-controller="controller">

    <input type="text" ng-model="name" />
    <input type="text" ng-model="surname" />
    <input type="button" ng-click="GetFullName()" value="Get Full Name" />
</div>

Pretty easy in your controller you do:

public function create()
{
    $user = new User;

    $action = URL::route('user.store');

    return View::('viewname')->with(compact('user', 'action'));
}

public function edit($id)
{
    $user = User::find($id);

    $action = URL::route('user.update', ['id' => $id]);

    return View::('viewname')->with(compact('user', 'action'));
}

And you just have to use this way:

{{ Form::model($user, ['action' => $action]) }}

   {{ Form::input('email') }}
   {{ Form::input('first_name') }}

{{ Form::close() }}

Since you declare sample inside the anonymous function you pass to ready, it is scoped to that function.

You then pass a string to setTimeout which is evaled after 2 seconds. This takes place outside the current scope, so it can't find the function.

Only pass functions to setTimeout, using eval is inefficient and hard to debug.

setTimeout(sample,2000)

Right click on the file with file explorer, choose Properties, then General tab and click on the Unblock button. This error message is very misleading.

To give a bit more specific answer. HTML5 allows you to get the geo coordinates, and it does a pretty decent job. Overall the browser support for geolocation is pretty good, all major browsers except ie7 and ie8 (and opera mini). IE9 does the job but is the worst performer. Checkout caniuse.com:

http://caniuse.com/#search=geol

Also you need the approval of your user to access their location, so make sure you check for this and give some decent instructions in case it's turned off. Especially for Iphone turning permissions on for Safari is a bit cumbersome.

You could try this if you only need the code to run when you have a debugger attached to the process.

if (Debugger.IsAttached)
{
     // do some stuff here
}

I got this error after using $.getJSON() from JQuery. I just changed to post:

data = getDataObjectByForm(form);
var jqxhr = $.post(url, data, function(){}, 'json')
    .done(function (response) {
        if (response instanceof Object)
            var json = response;
        else
            var json = $.parseJSON(response);
        // console.log(response);
        // console.log(json);
        jsonToDom(json);
        if (json.reload != undefined && json.reload)
            location.reload();
        $("body").delay(1000).css("cursor", "default");
    })
    .fail(function (jqxhr, textStatus, error) {
        var err = textStatus + ", " + error;
        console.log("Request Failed: " + err);
        alert("Fehler!");
    });

If you get the IP address from a DHCP server, you can also set the server to send a DNS server. Or add the nameserver 8.8.8.8 into /etc/resolvconf/resolv.conf.d/base file. The information in this file is included in the resolver configuration file even when no interfaces are configured.

Given this test file (test.txt)

Lorem ipsum dolor sit amet,
consectetur adipiscing elit. 
Duis eu diam non tortor laoreet 
bibendum vitae et tellus.

the following command will replace the first line to "newline text"

$ sed '1 c\
> newline text' test.txt

Result:

newline text

Duis eu diam non tortor laoreet 
bibendum vitae et tellus.

Replace @RunWith(MockitoJUnitRunner.class) with @RunWith(MockitoJUnitRunner.Silent.class).

The easiest way is to JSON-encode your object and then decode it back to an array:

$array = json_decode(json_encode($object), true);

Or if you prefer, you can traverse the object manually, too:

foreach ($object as $value) 
    $array[] = $value->post_id;

The easiest way to open an admin Powershell window in Windows 10 (and Windows 8) is to add a "Windows Powershell (Admin)" option to the "Power User Menu".

You can use auto-reload to reload the module without shutdown the server.

install

npm install auto-reload

example

data.json

{ "name" : "Alan" }

test.js

var fs = require('fs');
var reload = require('auto-reload');
var data = reload('./data', 3000); // reload every 3 secs

// print data every sec
setInterval(function() {
    console.log(data);
}, 1000);

// update data.json every 3 secs
setInterval(function() {
    var data = '{ "name":"' + Math.random() + '" }';
    fs.writeFile('./data.json', data);
}, 3000);

Result:

{ name: 'Alan' }
{ name: 'Alan' }
{ name: 'Alan' }
{ name: 'Alan' }
{ name: 'Alan' }
{ name: '0.8272748321760446' }
{ name: '0.8272748321760446' }
{ name: '0.8272748321760446' }
{ name: '0.07935990858823061' }

{ name: '0.20851597073487937' }

Intro

First off you have a string. JSON is not an array, an object, or a data structure. JSON is a text-based serialization format - so a fancy string, but still just a string. Decode it in PHP by using json_decode().

 $data = json_decode($json);

Therein you might find:

• scalars: strings, ints, floats, and bools
• nulls (a special type of its own)
• compound types: objects and arrays.

These are the things that can be encoded in JSON. Or more accurately, these are PHP's versions of the things that can be encoded in JSON.

There's nothing special about them. They are not "JSON objects" or "JSON arrays." You've decoded the JSON - you now have basic everyday PHP types.

Objects will be instances of stdClass, a built-in class which is just a generic thing that's not important here.

Accessing object properties

You access the properties of one of these objects the same way you would for the public non-static properties of any other object, e.g. $object->property.

$json = '
{
    "type": "donut",
    "name": "Cake"
}';

$yummy = json_decode($json);

echo $yummy->type; //donut

Accessing array elements

You access the elements of one of these arrays the same way you would for any other array, e.g. $array[0].

$json = '
[
    "Glazed",
    "Chocolate with Sprinkles",
    "Maple"
]';

$toppings = json_decode($json);

echo $toppings[1]; //Chocolate with Sprinkles

Iterate over it with foreach.

foreach ($toppings as $topping) {
    echo $topping, "\n";
}

Glazed
Chocolate with Sprinkles
Maple

Or mess about with any of the bazillion built-in array functions.

Accessing nested items

The properties of objects and the elements of arrays might be more objects and/or arrays - you can simply continue to access their properties and members as usual, e.g. $object->array[0]->etc.

$json = '
{
    "type": "donut",
    "name": "Cake",
    "toppings": [
        { "id": "5002", "type": "Glazed" },
        { "id": "5006", "type": "Chocolate with Sprinkles" },
        { "id": "5004", "type": "Maple" }
    ]
}';

$yummy = json_decode($json);

echo $yummy->toppings[2]->id; //5004

Passing true as the second argument to json_decode()

When you do this, instead of objects you'll get associative arrays - arrays with strings for keys. Again you access the elements thereof as usual, e.g. $array['key'].

$json = '
{
    "type": "donut",
    "name": "Cake",
    "toppings": [
        { "id": "5002", "type": "Glazed" },
        { "id": "5006", "type": "Chocolate with Sprinkles" },
        { "id": "5004", "type": "Maple" }
    ]
}';

$yummy = json_decode($json, true);

echo $yummy['toppings'][2]['type']; //Maple

Accessing associative array items

When decoding a JSON object to an associative PHP array, you can iterate both keys and values using the foreach (array_expression as $key => $value) syntax, eg

$json = '
{
    "foo": "foo value",
    "bar": "bar value",
    "baz": "baz value"
}';

$assoc = json_decode($json, true);
foreach ($assoc as $key => $value) {
    echo "The value of key '$key' is '$value'", PHP_EOL;
}

Prints

The value of key 'foo' is 'foo value'
The value of key 'bar' is 'bar value'
The value of key 'baz' is 'baz value'

Don't know how the data is structured

Read the documentation for whatever it is you're getting the JSON from.

Look at the JSON - where you see curly brackets {} expect an object, where you see square brackets [] expect an array.

Hit the decoded data with a print_r():

$json = '
{
    "type": "donut",
    "name": "Cake",
    "toppings": [
        { "id": "5002", "type": "Glazed" },
        { "id": "5006", "type": "Chocolate with Sprinkles" },
        { "id": "5004", "type": "Maple" }
    ]
}';

$yummy = json_decode($json);

print_r($yummy);

and check the output:

stdClass Object
(
    [type] => donut
    [name] => Cake
    [toppings] => Array
        (
            [0] => stdClass Object
                (
                    [id] => 5002
                    [type] => Glazed
                )

            [1] => stdClass Object
                (
                    [id] => 5006
                    [type] => Chocolate with Sprinkles
                )

            [2] => stdClass Object
                (
                    [id] => 5004
                    [type] => Maple
                )

        )

)

It'll tell you where you have objects, where you have arrays, along with the names and values of their members.

If you can only get so far into it before you get lost - go that far and hit that with print_r():

print_r($yummy->toppings[0]);

stdClass Object
(
    [id] => 5002
    [type] => Glazed
)

Take a look at it in this handy interactive JSON explorer.

Break the problem down into pieces that are easier to wrap your head around.

json_decode() returns null

This happens because either:

1. The JSON consists entirely of just that, null.
2. The JSON is invalid - check the result of json_last_error_msg or put it through something like JSONLint.
3. It contains elements nested more than 512 levels deep. This default max depth can be overridden by passing an integer as the third argument to json_decode().

If you need to change the max depth you're probably solving the wrong problem. Find out why you're getting such deeply nested data (e.g. the service you're querying that's generating the JSON has a bug) and get that to not happen.

Object property name contains a special character

Sometimes you'll have an object property name that contains something like a hyphen - or at sign @ which can't be used in a literal identifier. Instead you can use a string literal within curly braces to address it.

$json = '{"@attributes":{"answer":42}}';
$thing = json_decode($json);

echo $thing->{'@attributes'}->answer; //42

If you have an integer as property see: How to access object properties with names like integers? as reference.

Someone put JSON in your JSON

It's ridiculous but it happens - there's JSON encoded as a string within your JSON. Decode, access the string as usual, decode that, and eventually get to what you need.

$json = '
{
    "type": "donut",
    "name": "Cake",
    "toppings": "[{ \"type\": \"Glazed\" }, { \"type\": \"Maple\" }]"
}';

$yummy = json_decode($json);
$toppings = json_decode($yummy->toppings);

echo $toppings[0]->type; //Glazed

Data doesn't fit in memory

If your JSON is too large for json_decode() to handle at once things start to get tricky. See:

• Processing large JSON files in PHP
• How to properly iterate through a big json file

How to sort it

See: Reference: all basic ways to sort arrays and data in PHP.

function check (list){
    var foundRepeatingValue = false;
    var newList = [];
    for(i=0;i<list.length;i++){
        var thisValue = list[i];
        if(i>0){
            if(newList.indexOf(thisValue)>-1){
                foundRepeatingValue = true;
                console.log("getting repeated");
                return true;
            }
       } newList.push(thisValue);
    } return false;
}

var list1 = ["dse","dfg","dse"];
check(list1);

Output:

getting repeated
true

Also be careful with double-quotes -- on the Unix shell this expands variables. Some are obvious (like $foo and \t) but some are not (like !foo).

For safety, use single-quotes!

By definition dictionaries are unordered, and therefore cannot be indexed. For that kind of functionality use an ordered dictionary. Python Ordered Dictionary

I believe you can use something such as

if ___ (

do this

) else if ___ (

do this

)

var context = new DatabaseEntities();

var t = new test //Make sure you have a table called test in DB
{
    ID = Guid.NewGuid(),
    name = "blah",
};

context.test.Add(t);
context.SaveChanges();

Should do it

1. You can solve your problem by deleting folder JDK-9.
2. Restart Netbeans.
3. It will give you a message if you want to use the default version of JDK.
4. Press yes or ok.

Or you can remove JDK-9 from your pc and install JDK-8.

if you are using windows or linux operating system then type in command prompt / terminal

java -version

If java is correctly installed then you will get something like this

java version "1.7.0_25"
Java(TM) SE Runtime Environment (build 1.7.0_25-b15)
Java HotSpot(TM) Client VM (build 23.25-b01, mixed mode, sharing)

Side note: After installation of Java on a windows operating system, the PATH variable is changed to add java.exe so you need to re-open cmd.exe to reload the PATH variable.

Edit:

CD to the path first...

cd C:\ProgramData\Oracle\Java\javapath
java -version

An absolute URI specifies a scheme; a URI that is not absolute is said to be relative.

http://docs.oracle.com/javase/8/docs/api/java/net/URI.html

So, perhaps your URLEncoder isn't working as you're expecting (the https bit)?

    URLEncoder.encode(uri) 

Though the string parsing solution is the most popular, I don't like it, because parsing string can be a great performance hit in some situations.

When there is needed a kind of a bitfield or binary mask, I'd rather write it like

long bitMask = 1011001;

And later

int bit5 = BitField.GetBit(bitMask, 5);

Or

bool flag5 = BitField.GetFlag(bitMask, 5);`

Where BitField class is

public static class BitField
{
    public static int GetBit(int bitField, int index)
    {
        return (bitField / (int)Math.Pow(10, index)) % 10;
    }

    public static bool GetFlag(int bitField, int index)
    {
        return GetBit(bitField, index) == 1;
    }
}

use this way in xml

   <TextView
        android:id="@+id/myText"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Time is precious, so love now."
        android:gravity="center"
        android:textSize="30dp"
        android:textColor="#fff"
        />

Prepend functions with the '@' symbol to suppress certain errors, as opposed to turning off all error reporting.

More information: http://php.net/manual/en/language.operators.errorcontrol.php

PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.

@fsockopen();

default_keys = [1, "name"]

To get dictionary with None as values:

dict.fromkeys(default_keys)  

Output :

{1: None, 'name': None}

To get dictionary with default values:

dict.fromkeys(default_keys, [])  

Output :

{1: [], 'name': []}

You might try a lazy unmount:

umount -l

Using flexbox:

HTML:

<div class="wrapper">
    <img src="pikachu.gif"/>
</div>

CSS:

.wrapper {
    height: 300px;
    width: 300px;
    display: flex;
    align-items: flex-end;
}

As requested in some comments on another answer, the image can also be horizontally centred with justify-content: center;

As you read through the examples below, just keep in mind this difference

true === true // true
"string" === true // false
1 === true // false
{} === true // false

But

Boolean("string") === true // true
Boolean(1) === true // true
Boolean({}) === true // true

1. expect(statement).toBe(true)

Assertion passes when the statement passed to expect() evaluates to true

expect(true).toBe(true) // pass
expect("123" === "123").toBe(true) // pass

In all other cases cases it would fail

expect("string").toBe(true) // fail
expect(1).toBe(true); // fail
expect({}).toBe(true) // fail

Even though all of these statements would evaluate to true when doing Boolean():

So you can think of it as 'strict' comparison

2. expect(statement).toBeTrue()

This one does exactly the same type of comparison as .toBe(true), but was introduced in Jasmine recently in version 3.5.0 on Sep 20, 2019

3. expect(statement).toBeTruthy()

toBeTruthy on the other hand, evaluates the output of the statement into boolean first and then does comparison

expect(false).toBeTruthy() // fail
expect(null).toBeTruthy() // fail
expect(undefined).toBeTruthy() // fail
expect(NaN).toBeTruthy() // fail
expect("").toBeTruthy() // fail
expect(0).toBeTruthy() // fail

And IN ALL OTHER CASES it would pass, for example

expect("string").toBeTruthy() // pass
expect(1).toBeTruthy() // pass
expect({}).toBeTruthy() // pass

Kyle's solution worked perfectly fine for me so I made my research in order to avoid any Js and CSS, but just sticking with HTML. Adding a value of selected to the item we want to appear as a header forces it to show in the first place as a placeholder. Something like:

<option selected disabled>Choose here</option>

The complete markup should be along these lines:

<select>
    <option selected disabled>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

You can take a look at this fiddle, and here's the result:

If you do not want the sort of placeholder text to appear listed in the options once a user clicks on the select box just add the hidden attribute like so:

<select>
    <option selected disabled hidden>Choose here</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
    <option value="4">Four</option>
    <option value="5">Five</option>
</select>

Check the fiddle here and the screenshot below.

Here is the solution:

<select>
    <option style="display:none;" selected>Select language</option>
    <option>Option 1</option>
    <option>Option 2</option>
</select>

I was facing the same problem and I tried using JsonSetting to ignore the self-referencing error its kinda work until I got a class which self-referencing very deeply and my dot-net process hangs on Json writing value.

My Problem

    public partial class Company : BaseModel
{
    public Company()
    {
        CompanyUsers = new HashSet<CompanyUser>();
    }

    public string Name { get; set; }

    public virtual ICollection<CompanyUser> CompanyUsers { get; set; }
}

public partial class CompanyUser
{
    public int Id { get; set; }
    public int CompanyId { get; set; }
    public int UserId { get; set; }

    public virtual Company Company { get; set; }

    public virtual User User { get; set; }
}

public partial class User : BaseModel
{
    public User()
    {
        CompanyUsers = new HashSet<CompanyUser>();
    }

    public string DisplayName { get; set; }
    public virtual ICollection<CompanyUser> CompanyUsers { get; set; }

}

You can see the problem in User class it's referencing to CompanyUser class which is a self-referencing.

Now, I'm calling the GetAll Method which includes all the relational properties.

cs.GetAll("CompanyUsers", "CompanyUsers.User");

On this stage my DotNetCore process hangs on Executing JsonResult, writing value ... and never come. In my Startup.cs, I've already set the JsonOption. For some reason EFCore is including nested property which I'm not asking Ef to give.

    options.SerializerSettings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

expected behavior should be this

Hey EfCore can you please include "CompanyUsers" data as well in my Company class so that i can easily access the data.

then

Hey EfCore can you also please include the "CompanyUsers.User" data as well so that i can easily access the data like this Company.CompanyUsers.First().User.DisplayName

at this stage i should only get this "Company.CompanyUsers.First().User.DisplayName" and it should not give me Company.CompanyUsers.First().User.CompanyUsers which causing the self-referencing issue; Technically it shouldn't give me User.CompanyUsers as CompanyUsers is a navigational property. But, EfCore get very excited and giving me User.CompanyUsers.

So, I decided to write an extension method for property to be excluded from the object (it's actually not excluding it's just setting the property to null). Not only that it will also work on array properties as well. below is the code I'm also going to export the nuget package for other users (not sure if this even helps someone). Reason is simple because I'm too lazy to write .Select(n => new { n.p1, n.p2}); I just don't want to write select statement to exclude only 1 property!

This is not the best code (I'll update at some stage) as I have written in a hurry and though this might help someone who wants to exclude (set null) in the object with arrays also.

    public static class PropertyExtensions
{
    public static void Exclude<T>(this T obj, Expression<Func<T, object>> expression)
    {
        var visitor = new PropertyVisitor<T>();
        visitor.Visit(expression.Body);
        visitor.Path.Reverse();
        List<MemberInfo> paths = visitor.Path;
        Action<List<MemberInfo>, object> act = null;

        int recursiveLevel = 0;
        act = (List<MemberInfo> vPath, object vObj) =>
        {

            // set last propert to null thats what we want to avoid the self-referencing error.
            if (recursiveLevel == vPath.Count - 1)
            {
                if (vObj == null) throw new ArgumentNullException("Object cannot be null");

                vObj.GetType().GetMethod($"set_{vPath.ElementAt(recursiveLevel).Name}").Invoke(vObj, new object[] { null });
                return;
            }

            var pi = vObj.GetType().GetProperty(vPath.ElementAt(recursiveLevel).Name);
            if (pi == null) return;
            var pv = pi.GetValue(vObj, null);
            if (pi.PropertyType.IsArray || pi.PropertyType.Name.Contains("HashSet`1") || pi.PropertyType.Name.Contains("ICollection`1"))
            {
                var ele = (IEnumerator)pv.GetType().GetMethod("GetEnumerator").Invoke(pv, null);

                while (ele.MoveNext())
                {
                    recursiveLevel++;
                    var arrItem = ele.Current;

                    act(vPath, arrItem);

                    recursiveLevel--;
                }

                if (recursiveLevel != 0) recursiveLevel--;
                return;
            }
            else
            {
                recursiveLevel++;
                act(vPath, pv);
            }

            if (recursiveLevel != 0) recursiveLevel--;

        };

        // check if the root level propert is array
        if (obj.GetType().IsArray)
        {
            var ele = (IEnumerator)obj.GetType().GetMethod("GetEnumerator").Invoke(obj, null);
            while (ele.MoveNext())
            {
                recursiveLevel = 0;
                var arrItem = ele.Current;

                act(paths, arrItem);
            }
        }
        else
        {
            recursiveLevel = 0;
            act(paths, obj);
        }

    }

    public static T Explode<T>(this T[] obj)
    {
        return obj.FirstOrDefault();
    }

    public static T Explode<T>(this ICollection<T> obj)
    {
        return obj.FirstOrDefault();
    }
}

above extension class will give you the ability to set the property to null to avoid the self-referencing loop even arrays.

    internal class PropertyVisitor<T> : ExpressionVisitor

                }
            }
        };

Cases:

Case 1: Exclude only property without any array

p.Exclude(n => n.AddressDetail.CountryDetail.CountryName);

Case 2: Exclude property with 1 array

p1.Exclude(n => n.AddressDetail.CountryDetail2.Explode().CountryName);

Case 3: Exclude property with 2 nested array

p1.Exclude(n => n.AddressDetail.CountryDetail2.Explode().CountryDetail.Explode().Name);

Case 4: EF GetAll Query With Includes

var query = cs.GetAll("CompanyUsers", "CompanyUsers.User").ToArray();
query.Exclude(n => n.Explode().CompanyUsers.Explode().User.CompanyUsers);
return query;

You have notice that Explode() method its also a extension method just for our expression builder to get the property from array property. Whenever there is a array property use the .Explode().YourPropertyToExclude or .Explode().Property1.MyArrayProperty.Explode().MyStupidProperty. Above code helps me to avoid the self-referencing so deep as deep i want. Now i can use GetAll and exclude the property which i don;t want!

Swift 2.x answer:

    dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
        self.getResultSetFromDB(docids)
    }

PHP 7.4 style:

$ids = array_map(fn(string $x): int => (int) $x, explode(',', $string));

It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.

In my case that URL is not working in browser also.

I check with https://www.google.com/

webView.loadUrl("https://www.google.com/")

And it worked for me.

I once copied these files to the database storage folder for a mysql database which was working, started the db and waited for it to "repair" the files, then extracted them with mysqldump.

DateTime.Now is what you're searching for...

I am posting this answer to provide a script with explanations that covers three different scenarios of creating a local repo that has a local remote. You can run the entire script and it will create the test repos in your home folder (tested on windows git bash). The explanations are inside the script for easier saving to your personal notes, its very readable from, e.g. Visual Studio Code.

I would also like to thank Jack for linking to this answer where adelphus has good, detailed, hands on explanations on the topic.

This is my first post here so please advise what should be improved.

## SETUP LOCAL GIT REPO WITH A LOCAL REMOTE
# the main elements:
# - remote repo must be initialized with --bare parameter
# - local repo must be initialized
# - local repo must have at least one commit that properly initializes a branch(root of the commit tree)
# - local repo needs to have a remote
# - local repo branch must have an upstream branch on the remote

{ # the brackets are optional, they allow to copy paste into terminal and run entire thing without interruptions, run without them to see which cmd outputs what

cd ~
rm -rf ~/test_git_local_repo/

## Option A - clean slate - you have nothing yet

mkdir -p ~/test_git_local_repo/option_a ; cd ~/test_git_local_repo/option_a
git init --bare local_remote.git # first setup the local remote
git clone local_remote.git local_repo # creates a local repo in dir local_repo
cd ~/test_git_local_repo/option_a/local_repo
git remote -v show origin # see that git clone has configured the tracking
touch README.md ; git add . ; git commit -m "initial commit on master" # properly init master
git push origin master # now have a fully functional setup, -u not needed, git clone does this for you

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branches and their respective remote upstream branches with the initial commit
git remote -v show origin # see all branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote

## Option B - you already have a local git repo and you want to connect it to a local remote

mkdir -p ~/test_git_local_repo/option_b ; cd ~/test_git_local_repo/option_b
git init --bare local_remote.git # first setup the local remote

# simulate a pre-existing git local repo you want to connect with the local remote
mkdir local_repo ; cd local_repo
git init # if not yet a git repo
touch README.md ; git add . ; git commit -m "initial commit on master" # properly init master
git checkout -b develop ; touch fileB ; git add . ; git commit -m "add fileB on develop" # create develop and fake change

# connect with local remote
cd ~/test_git_local_repo/option_b/local_repo
git remote add origin ~/test_git_local_repo/option_b/local_remote.git
git remote -v show origin # at this point you can see that there is no the tracking configured (unlike with git clone), so you need to push with -u
git push -u origin master # -u to set upstream
git push -u origin develop # -u to set upstream; need to run this for every other branch you already have in the project

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branch(es) and its remote upstream with the initial commit
git remote -v show origin # see all remote branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote

## Option C - you already have a directory with some files and you want it to be a git repo with a local remote

mkdir -p ~/test_git_local_repo/option_c ; cd ~/test_git_local_repo/option_c
git init --bare local_remote.git # first setup the local remote

# simulate a pre-existing directory with some files
mkdir local_repo ; cd local_repo ; touch README.md fileB

# make a pre-existing directory a git repo and connect it with local remote
cd ~/test_git_local_repo/option_c/local_repo
git init
git add . ; git commit -m "inital commit on master" # properly init master
git remote add origin ~/test_git_local_repo/option_c/local_remote.git
git remote -v show origin # see there is no the tracking configured (unlike with git clone), so you need to push with -u
git push -u origin master # -u to set upstream

# check all is set-up correctly
git pull # check you can pull
git branch -avv # see local branch and its remote upstream with the initial commit
git remote -v show origin # see all remote branches are set to pull and push to remote
git log --oneline --graph --decorate --all # see all commits and branches tips point to the same commits for both local and remote
}

This method works for me using the hyperlink function:

=HYPERLINK("http://"&B10,B10)

Where B10 is the cell containing the text version of the URL (in this example).

Well I know this might be a big change or even not suitable for your project, but did you consider not performing the push until you already have the data? That way you only need to draw the view once and the user experience will also be better - the push will move in already loaded.

The way you do this is in the UITableView didSelectRowAtIndexPath you asynchronously ask for the data. Once you receive the response, you manually perform the segue and pass the data to your viewController in prepareForSegue. Meanwhile you may want to show some activity indicator, for simple loading indicator check https://github.com/jdg/MBProgressHUD

Guava provides an onlyElement Collector, but only use it if you expect the collection to have exactly one element.

Collection<String> stringCollection = ...;
String string = collection.stream().collect(MoreCollectors.onlyElement())

If you are unsure of how many elements there are, use findFirst.

Optional<String> optionalString = collection.stream().findFirst();

No, there isn't a syntax for extracting text using regular expressions. You have to use the ordinary string manipulation functions.

Alternatively select the entire value from the database (or the first n characters if you are worried about too much data transfer) and then use a regular expression on the client.

"Rounded" down as in your example. This will return a varchar value of the date.

DECLARE @date As DateTime2
SET @date = '2007-09-22 15:07:38.850'

SELECT CONVERT(VARCHAR(16), @date, 120) --2007-09-22 15:07
SELECT CONVERT(VARCHAR(13), @date, 120) --2007-09-22 15

i think the best response is to look into files imports , some imports has a problem .

example : include #import "file.m" or include external file.h

If you store an object in session state, that object must be serializable.

http://www.hpenterprisesecurity.com/vulncat/en/vulncat/dotnet/asp_dotnet_bad_practices_non_serializable_object_stored_in_session.html

edit:

In order for the session to be serialized correctly, all objects the application stores as session attributes must declare the [Serializable] attribute. Additionally, if the object requires custom serialization methods, it must also implement the ISerializable interface.

image

Variable-length binary data from 0 through 2^31-1 (2,147,483,647) bytes. Still it IS supported to use image datatype, but be aware of:

https://docs.microsoft.com/en-us/sql/t-sql/data-types/binary-and-varbinary-transact-sql

varbinary [ ( n | max) ]

Variable-length binary data. n can be a value from 1 through 8,000. max indicates that the maximum storage size is 2^31-1 bytes. The storage size is the actual length of the data entered + 2 bytes. The data that is entered can be 0 bytes in length. The ANSI SQL synonym for varbinary is binary varying.

So both are equally in size (2GB). But be aware of:

https://docs.microsoft.com/en-us/sql/database-engine/deprecated-database-engine-features-in-sql-server-2016#features-not-supported-in-a-future-version-of-sql-server

Though the end of "image" datatype is still not determined, you should use the "future" proof equivalent.

But you have to ask yourself: why storing BLOBS in a Column?

https://docs.microsoft.com/en-us/sql/relational-databases/blob/compare-options-for-storing-blobs-sql-server

when using String array, you have to give size of array while initializing

eg

String[] str = new String[10];

you can use index 0-9 to store values

str[0] = "value1"
str[1] = "value2"
str[2] = "value3"
str[3] = "value4"
str[4] = "value5"
str[5] = "value6"
str[6] = "value7"
str[7] = "value8"
str[8] = "value9"
str[9] = "value10"

if you are using ArrayList instread of string array, you can use it without initializing size of array ArrayList str = new ArrayList();

you can add value by using add method of Arraylist

str.add("Value1");

get retrieve a value from arraylist, you can use get method

String s = str.get(0);

find total number of items by size method

int nCount = str.size();

One way is to do:

sys.exit(0)

You will have to import sys of course.

Another way is to break out of your infinite loop. For example, you could do this:

while True:
    choice = get_input()
    if choice == "a":
        # do something
    elif choice == "q":
        break

Yet another way is to put your main loop in a function, and use return:

def run():
    while True:
        choice = get_input()
        if choice == "a":
            # do something
        elif choice == "q":
            return

if __name__ == "__main__":
    run()

The only reason you need the run() function when using return is that (unlike some other languages) you can't directly return from the main part of your Python code (the part that's not inside a function).

var name = this.name;
$("input[name=" + name + "]").hide();

OR you can do something like this.

var id = this.id;
$('#' + id).hide();

OR you can give some effect also.

$("#" + this.id).slideUp();

If you want to remove the entire element permanently form the page.

$("#" + this.id).remove();

You can also use it in this also.

$("#" + this.id).slideUp('slow', function (){
    $("#" + this.id).remove();
});

There's a kind of hack-tastic way to do it if you have php enabled on your server. Change this line:

url:   'http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml',

to this line:

url: '/path/to/phpscript.php',

and then in the php script (if you have permission to use the file_get_contents() function):

<?php

header('Content-type: application/xml');
echo file_get_contents("http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml");

?>

Php doesn't seem to mind if that url is from a different origin. Like I said, this is a hacky answer, and I'm sure there's something wrong with it, but it works for me.

Edit: If you want to cache the result in php, here's the php file you would use:

<?php

$cacheName = 'somefile.xml.cache';
// generate the cache version if it doesn't exist or it's too old!
$ageInSeconds = 3600; // one hour
if(!file_exists($cacheName) || filemtime($cacheName) > time() + $ageInSeconds) {
  $contents = file_get_contents('http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml');
  file_put_contents($cacheName, $contents);
}

$xml = simplexml_load_file($cacheName);

header('Content-type: application/xml');
echo $xml;

?>

Caching code take from here.

This works very fine for me. It submit the farm and make button disable and after 2 sec active the button.

<button id="submit" type="submit" onclick="submitLimit()">Yes</button>

function submitLimit() {
var btn = document.getElementById('submit')
setTimeout(function() {
    btn.setAttribute('disabled', 'disabled');
}, 1);

setTimeout(function() {
    btn.removeAttribute('disabled');
}, 2000);}

In ECMA6 Syntex

function submitLimit() {
submitBtn = document.getElementById('submit');

setTimeout(() => { submitBtn.setAttribute('disabled', 'disabled') }, 1);

setTimeout(() => { submitBtn.removeAttribute('disabled') }, 4000);}

If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.

To create multiple sub-folders

mkdir -p parentfolder/{subfolder1,subfolder2,subfolder3}

Based on Anastasiya's answer. I think this is the shortest vba command:

Option Explicit

Sub Sample()
    Dim sColumnLetter as String
    Dim iColumnNumber as Integer

    sColumnLetter = "C"
    iColumnNumber = Columns(sColumnLetter).Column

    MsgBox "The column number is " & iColumnNumber
End Sub

Caveat: The only condition for this code to work is that a worksheet is active, because Columns is equivalent to ActiveSheet.Columns. ;)

I wanted to add something to the answer already provided. maven-compiler-plugin by default will compile your project using Java 1.5 which is where m2e get's its information.

That's why you have to explicitly declare the maven-compiler-plugin in your project with something other then 1.5. Your effective pom.xml will implicitly use the default set in the maven-compiler-plugin pom.xml.

I had the same issue, fixed by rebuild and redeploy ALL Dependents Dll files

You can manage selecting those elements without any form of regex as the previous answers show, but to answer the question directly, yes you can use a form of regex in selectors:

#sections div[id^='s'] {
    color: red;  
}

That says select any div elements inside the #sections div that have an ID starting with the letter 's'.

See fiddle here.

W3 CSS selector docs here.

v$session_longops

If you look for sofar != totalwork you'll see ones that haven't completed, but the entries aren't removed when the operation completes so you can see a lot of history there too.

Plain JavaScript:

You don't need jQuery to do something trivial like this. Just use the .removeAttribute() method.

Assuming you are just targeting a single element, you can easily use the following: (example)

document.querySelector('#target').removeAttribute('style');

If you are targeting multiple elements, just loop through the selected collection of elements: (example)

var target = document.querySelectorAll('div');
Array.prototype.forEach.call(target, function(element){
    element.removeAttribute('style');
});

Array.prototype.forEach() - IE9 and above / .querySelectorAll() - IE 8 (partial) IE9 and above.

There is no pure CSS solution to this classical problem.

If you want to achieve this, you have two solutions:

• Using a table (ugly, non semantic, but the only way to vertically align things that are not a single line of text)
• Listening to window.resize and absolute positionning

EDIT: when I say that there is no solution, I take as an hypothesis that you don't know in advance the size of the block to center. If you know it, paislee's solution is very good

In my case we were setting the div id as a number and setting the href="#123", this did not work.. adding a prefix to the id helped.

Example: This did not work-

<li> <a data-toggle="tab" href="#@i"> <li/>
...
<div class="tab-pane" id="#@i">

This worked:

<li><a data-toggle="tab" href="#prefix@i"><li/>
...
<div class="tab-pane" id="#prefix@i">

You don't need the separate fill item. In fact, it's invalid. You just have to add a solid block to the shape. The subsequent stroke draws on top of the solid:

<shape 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:shape="rectangle">

    <corners android:radius="5dp" />
    <solid android:color="@android:color/white" />
    <stroke
        android:width="1dip"
        android:color="@color/bggrey" />
</shape>

You also don't need the layer-list if you only have one shape.

while there is no quick and standard way to determine it, this will output it:

#include <stdio.h> 
int main()  
{ 
   unsigned int i = 1; 
   char *c = (char*)&i; 
   if (*c)     
       printf("Little endian"); 
   else
       printf("Big endian"); 
   getchar(); 
   return 0; 
} 

All you need just run a test wait till finish, after that go to Build Setting, Search in to Build Setting Inference, change swift 3 @objc Inference to (Default). that's all what i did and worked perfect.

Yet another summary introduction, inspired by this post.

import argparse

# define functions, classes, etc.

# executes when your script is called from the command-line
if __name__ == "__main__":

    parser = argparse.ArgumentParser()
    #
    # define each option with: parser.add_argument
    #
    args = parser.parse_args() # automatically looks at sys.argv
    #
    # access results with: args.argumentName
    #

Arguments are defined with combinations of the following:

parser.add_argument( 'name', options... )              # positional argument
parser.add_argument( '-x', options... )                # single-char flag
parser.add_argument( '-x', '--long-name', options... ) # flag with long name

Common options are:

• help: description for this arg when --help is used.
• default: default value if the arg is omitted.
• type: if you expect a float or int (otherwise is str).
• dest: give a different name to a flag (e.g. '-x', '--long-name', dest='longName').
  Note: by default --long-name is accessed with args.long_name
• action: for special handling of certain arguments
  • store_true, store_false: for boolean args
    '--foo', action='store_true' => args.foo == True
  • store_const: to be used with option const
'--foo', action='store_const', const=42 => args.foo == 42
  • count: for repeated options, as in ./myscript.py -vv
'-v', action='count' => args.v == 2
  • append: for repeated options, as in ./myscript.py --foo 1 --foo 2
'--foo', action='append' => args.foo == ['1', '2']
• required: if a flag is required, or a positional argument is not.
• nargs: for a flag to capture N args
  ./myscript.py --foo a b => args.foo = ['a', 'b']
• choices: to restrict possible inputs (specify as list of strings, or ints if type=int).

In .NET you don't find only C#. You can find Visual Basic for example. If a job requires .NET knowledge, probably it need a programmer who knows the entire set of languages provided by the .NET framework.

This is a function online, I created a header file with it, and I use Setcolor(); instead, I hope this helped! You can change the color by choosing any color in the range of 0-256. :) Sadly, I believe CodeBlocks has a later build of the window.h library...

#include <windows.h>            //This is the header file for windows.
#include <stdio.h>              //C standard library header file

void SetColor(int ForgC);

int main()
{
    printf("Test color");       //Here the text color is white
    SetColor(30);               //Function call to change the text color
    printf("Test color");       //Now the text color is green
    return 0;
}

void SetColor(int ForgC)
{
     WORD wColor;
     //This handle is needed to get the current background attribute

     HANDLE hStdOut = GetStdHandle(STD_OUTPUT_HANDLE);
     CONSOLE_SCREEN_BUFFER_INFO csbi;
     //csbi is used for wAttributes word

     if(GetConsoleScreenBufferInfo(hStdOut, &csbi))
     {
          //To mask out all but the background attribute, and to add the color
          wColor = (csbi.wAttributes & 0xF0) + (ForgC & 0x0F);
          SetConsoleTextAttribute(hStdOut, wColor);
     }
     return;
}

Thank you, everybody. I tested the code snippets here on the recent browsers: Chrome 55, Firefox 50, IE 11 and Edge 38 and I came up with the following combination that worked for me for all of them. I'm sure it can be improved, but it's a quick solution for whoever needs:

var browser_name = '';
isIE = /*@cc_on!@*/false || !!document.documentMode;
isEdge = !isIE && !!window.StyleMedia;
if(navigator.userAgent.indexOf("Chrome") != -1 && !isEdge)
{
    browser_name = 'chrome';
}
else if(navigator.userAgent.indexOf("Safari") != -1 && !isEdge)
{
    browser_name = 'safari';
}
else if(navigator.userAgent.indexOf("Firefox") != -1 ) 
{
    browser_name = 'firefox';
}
else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
{
    browser_name = 'ie';
}
else if(isEdge)
{
    browser_name = 'edge';
}
else 
{
   browser_name = 'other-browser';
}
$('html').addClass(browser_name);

It adds a CSS class to the HTML, with the name of the browser.

There is another way to find the page update which could be useful for some occasions (if works:).

If the page has been indexed by Google, or by Wayback Machine you can try to find out what date(s) was(were) saved by them (these methods do not work for any page, and have some limitations, which are extensively investigated in this webmasters.stackexchange question's answers. But in many cases they can help you to find out the page update date(s):

1. Google way: Go by link https://www.google.com.ua/search?q=site%3Awww.example.com&biw=1855&bih=916&source=lnt&tbs=cdr%3A1%2Ccd_min%3A1%2F1%2F2000%2Ccd_max%3A&tbm=
   • You can change text in search field by any page URL you want.
   • For example, the current stackoverflow question page search gives us as a result May 14, 2014 - which is the question creation date:
2. Wayback machine way: Go by link https://web.archive.org/web/*/www.example.com
   • for this stackoverflow page wayback machine gives us more results: Saved 6 times between June 7, 2014 and November 23, 2016., and you can view all saved copies for each date

Like Eliran Malka asked, why do you need to check for IE 9?

Detecting browser make and version is generally a bad smell. This generally means that you there is a bigger problem with the code if you need JavaScript to detect specific versions of browser.

There are genuine cases where a feature won't work, like say WebSockets isn't supported in IE 8 or 9. This should be solved by checking for WebSocket support, and applying a polyfill if there is no native support.

This should be done with a library like Modernizr.

That being said, you can easily create service that would return the browser. There are valid cases where a feature exists in a browser but the implementation is outdated or broken. Modernizr is not appropriate for these cases.

app.service('browser', ['$window', function($window) {

     return function() {

         var userAgent = $window.navigator.userAgent;

        var browsers = {chrome: /chrome/i, safari: /safari/i, firefox: /firefox/i, ie: /internet explorer/i};

        for(var key in browsers) {
            if (browsers[key].test(userAgent)) {
                return key;
            }
       };

       return 'unknown';
    }

}]);

Fixed typo broswers

Note: This is just an example of how to create a service in angular that will sniff the userAgent string. This is just a code example that is not expected to work in production and report all browsers in all situations.

UPDATE

It is probably best to use a third party library like https://github.com/ded/bowser or https://github.com/darcyclarke/Detect.js. These libs place an object on the window named bowser or detect respectively.

You can then expose this to the Angular IoC Container like this:

angular.module('yourModule').value('bowser', bowser);

Or

detectFactory.$inject = ['$window'];
function detectFactory($window) {
    return detect.parse($window.navigator.userAgent);
} 
angular.module('yourModule').factory('detect', detectFactory);

You would then inject one of these the usual way, and use the API provided by the lib. If you choose to use another lib that instead uses a constructor method, you would create a factory that instantiates it:

function someLibFactory() {
    return new SomeLib();
}
angular.module('yourModule').factory('someLib', someLibFactory);

You would then inject this into your controllers and services the normal way.

If the library you are injecting does not exactly match your requirements, you may want to employ the Adapter Pattern where you create a class/constructor with the exact methods you need.

In this example we just need to test for IE 9, and we are going to use the bowser lib above.

BrowserAdapter.$inject = ['bowser']; // bring in lib
function BrowserAdapter(bowser) {
    this.bowser = bowser;
}

BrowserAdapter.prototype.isIe9 = function() {
    return this.bowser.msie && this.browser.version == 9;
}

angular.module('yourModule').service('browserAdapter', BrowserAdapter);

Now in a controller or service you can inject the browserAdapter and just do if (browserAdapter.isIe9) { // do something }

If later you wanted to use detect instead of bowser, the changes in your code would be isolated to the BrowserAdapter.

UPDATE

In reality these values never change. IF you load the page in IE 9 it will never become Chrome 44. So instead of registering the BrowserAdapter as a service, just put the result in a value or constant.

angular.module('app').value('isIe9', broswerAdapter.isIe9);

Time Picker In swift

class ViewController: UIViewController {
    
    //timePicker
    @IBOutlet weak var lblTime: UILabel!
    @IBOutlet weak var timePicker: UIDatePicker!
    @IBOutlet weak var cancelTime_Btn: UIBarButtonItem!
    @IBOutlet weak var donetime_Btn: UIBarButtonItem!
    @IBOutlet weak var toolBar: UIToolbar!
    
    //Date picker
//    @IBOutlet weak var datePicker: UIDatePicker!
    
    override func viewDidLoad() {
        super.viewDidLoad()
        ishidden(bool: true)
        let dateFormatter2 = DateFormatter()
        dateFormatter2.dateFormat = "HH:mm a" //"hh:mm a"
        lblTime.text = dateFormatter2.string(from: timePicker.date)
        
    }
    
    @IBAction func selectTime_Action(_ sender: Any) {
        timePicker.datePickerMode = .time
        ishidden(bool: false)
    }
    
    @IBAction func timeCancel_Action(_ sender: Any) {
        ishidden(bool: true)
    }
    
    @IBAction func timeDoneBtn(_ sender: Any) {
        let dateFormatter1 = DateFormatter()
        dateFormatter1.dateFormat =  "HH:mm a"//"hh:mm"
        
        let str = dateFormatter1.string(from: timePicker.date)
        lblTime.text = str
        
        ishidden(bool: true)
        
    }
    
    func ishidden(bool:Bool){
           timePicker.isHidden = bool
           toolBar.isHidden = bool
       }
}

You could try this:

        <script type="text/javascript">
         function newWindow(url){
                window.open(url);
            }
        </script>

And call the function

I have been having this issue with SweetAlert2 as well. SA2 differs from 1 and puts everything inside the result object. The following above can be accomplished with the following code.

Swal.fire({
    title: 'A cool title',
    icon: 'info',
    confirmButtonText: 'Log in'
  }).then((result) => {
    if (result['isConfirmed']){
      // Put your function here
    }
  })

Everything placed inside the then result will run. Result holds a couple of parameters which can be used to do the trick. Pretty simple technique. Not sure if it works the same on SweetAlert1 but I really wouldn't know why you would choose that one above the newer version.

There is also another way:

Fragment.instantiate(context, MyFragment.class.getName(), myBundle)

Solution from proxy side, I faced some problems in the SSL handshake process and I had to force my proxy server to send requests using HTTP/1.0 to solve the problem by setting this argument in the httpd.conf SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 after that I faced the 417 error as my clients application was using HTTP/1.1 and the proxy was forced to use HTTP/1.0, the problem was solved by setting this parameter in the httpd.conf on the proxy side RequestHeader unset Expect early without the need to change anything in the client side, hope this helps.

As you are not trying to move the files around in the tree, you should be able to just checkout the directory:

git checkout master -- dirname

Considering the typical top-level class. Only public and no modifier access modifiers may be used at the top level so you'll either see public or you won't see any access modifier at all.

`static`` is used because you may not have a need to create an actual object at the top level (but sometimes you will want to so you may not always see/use static. There are other reasons why you wouldn't include static too but this is the typical one at the top level.)

void is used because usually you're not going to be returning a value from the top level (class). (sometimes you'll want to return a value other than NULL so void may not always be used either especially in the case when you have declared, initialized an object at the top level that you are assigning some value to).

Disclaimer: I'm a newbie myself so if this answer is wrong in any way please don't hang me. By day I'm a tech recruiter not a developer; coding is my hobby. Also, I'm always open to constructive criticism and love to learn so please feel free to point out any errors.

Use the beginning and end anchors.

Regex regex = new Regex(@"^\d$");

Use "^\d+$" if you need to match more than one digit.

Note that "\d" will match [0-9] and other digit characters like the Eastern Arabic numerals ??????????. Use "^[0-9]+$" to restrict matches to just the Arabic numerals 0 - 9.

If you need to include any numeric representations other than just digits (like decimal values for starters), then see @tchrist's comprehensive guide to parsing numbers with regular expressions.

You can always make it a function

function writeObject(color){
    $('body').append('<div style="color:'+color+';">Hello!</div>')
}

writeObject('blue') ?

Why not show create table myTable ?

Someone told me this but I didn't see anyone mention here, anything bad?

It's neat if you just want to take a glance at the indexes along with column infomations.

Alternatively, you can make a function that executes tasks based on the value of its "Static" variables, example below:

<!DOCTYPE html>

<div id="Time_Box"> Time </div>

<button type="button" onclick='Update_Time("on")'>Update Time On</button>
<button type="button" onclick='Update_Time("off")'>Update Time Off</button>

<script>

var Update_Time = (function () {     //_____________________________________________________________

var Static = [];             //"var" declares "Static" variable as static object in this function

    return function (Option) {

    var Local = [];           //"var" declares "Local" variable as local object in this function

        if (typeof Option === 'string'){Static.Update = Option};

        if (Static.Update === "on"){
        document.getElementById("Time_Box").innerText = Date();

        setTimeout(function(){Update_Time()}, 1000);    //update every 1 seconds
        };

    };

})();  

Update_Time('on');    //turns on time update

</script>

To get a list of all childs of a specific type you can use:

private static IEnumerable<DependencyObject> FindInVisualTreeDown(DependencyObject obj, Type type)
{
    if (obj != null)
    {
        if (obj.GetType() == type)
        {
            yield return obj;
        }

        for (var i = 0; i < VisualTreeHelper.GetChildrenCount(obj); i++)
        {
            foreach (var child in FindInVisualTreeDown(VisualTreeHelper.GetChild(obj, i), type))
            {
                if (child != null)
                {
                    yield return child;
                }
            }
        }
    }

    yield break;
}

Answer for PyCharm 2016.1 on OSX: (This is an update to the answer by @GeorgeWilliams993's answer above, but I don't have the rep yet to make comments.)

Go to Pycharm menu --> Preferences --> Project: (projectname) --> Project Interpreter

At the top is a popup for "Project Interpreter," and to the right of it is a button with ellipses (...) - click on this button for a different popup and choose "More" (or, as it turns out, click on the main popup and choose "Show All").

This shows a list of interpreters, with one selected. At the bottom of the screen are a set of tools... pick the rightmost one:

Now you should see all the paths pycharm is searching to find imports, and you can use the "+" button at the bottom to add a new path.

I think the most significant difference from @GeorgeWilliams993's answer is that the gear button has been replaced by a set of ellipses. That threw me off.

Per this link:

the symptom could occur if the replication service tries to use the ports that occupied by others, or by a malfunction NIC. Please try the following steps:

1. Restart the windows firewall service
2. Reboot the problematic machine
3. Restart the “TCP/IP stack”. Run CMD as administrator, type “netsh int ip reset resetlog.txt” to reset TCP/IP.
4. Try to temporarily disable antivirus.

If you installed Anaconda with Visual Studio 2017 for Windows, conda executable is in this path or similar.

In my case path is this: C:\Program Files (x86)\Microsoft Visual Studio\Shared\Anaconda3_64\Scripts

Steps to add it to your PATH:

• On the Windows desktop, right-click My Computer.
• In the pop-up menu, click Properties.
• In the System Properties window, click the Advanced tab, and then click Environment Variables.
• In the System Variables window, highlight Path, and click Edit.
• Add your path and restart your cmd.

You will be able to execute conda

Happy coding!

Web.config:

<connectionStrings>
    <add name="ConnStringDb" connectionString="Data Source=localhost;
         Initial Catalog=DatabaseName; Integrated Security=True;" 
         providerName="System.Data.SqlClient" />
</connectionStrings>

c# code:

using System.Configuration;
using System.Data

SqlConnection _connection = new SqlConnection(
          ConfigurationManager.ConnectionStrings["ConnStringDb"].ToString());

try
{
    if(_connection.State==ConnectionState.Closed)
        _connection.Open();
}
catch { }

If your last field is a single character, you could do this:

a="1:2:3:4:5"

echo ${a: -1}
echo ${a:(-1)}

Check string manipulation in bash.

If you are using any user control and want to get any text box values then you can use the below code:

var result = document.getElementById('LE_OtherCostsDetails_txtHomeOwnerInsurance').value;

Here, LE_OtherCostsDetails, is the name of the user control and txtHomeOwnerInsurance is the id of the text box.

Yes, you can put arrays in sessions, example:

$_SESSION['name_here'] = $your_array;

Now you can use the $_SESSION['name_here'] on any page you want but make sure that you put the session_start() line before using any session functions, so you code should look something like this:

 session_start();
 $_SESSION['name_here'] = $your_array;

Possible Example:

 session_start();
 $_SESSION['name_here'] = $_POST;

Now you can get field values on any page like this:

 echo $_SESSION['name_here']['field_name'];

As for the second part of your question, the session variables remain there unless you assign different array data:

 $_SESSION['name_here'] = $your_array;

Session life time is set into php.ini file.

The error usually means that the port you are trying to open is being already used by another application. Try using netstat to see which ports are open and then use an available port.

Also check if you are binding to the right ip address (I am assuming it would be localhost)

In phpMyAdmin, click the table, and then click the Import tab at the top of the page.

Browse and open the csv file. Leave the charset as-is. Uncheck partial import unless you have a HUGE dataset (or slow server). The format should already have selected “CSV” after selecting your file, if not then select it (not using LOAD DATA). If you want to clear the whole table before importing, check “Replace table data with file”. Optionally check “Ignore duplicate rows” if you think you have duplicates in the CSV file. Now the important part, set the next four fields to these values:

Fields terminated by: ,
Fields enclosed by: “
Fields escaped by: \
Lines terminated by: auto

Currently these match the defaults except for “Fields terminated by”, which defaults to a semicolon.

Now click the Go button, and it should run successfully.

If you know the last SHA1 of the branch, you can try

git branch branchName <SHA1>

You can find the SHA1 using git reflog, described in the solution --defect link--.

Note that you have to be careful if your row contains a factor. Here is an example:

df_1 = data.frame(V1 = factor(11:15),
                  V2 = 21:25)
df_1[1,] %>% as.numeric() # you expect 11 21 but it returns 
[1] 1 21

Here is another example (by default data.frame() converts characters to factors)

df_2 = data.frame(V1 = letters[1:5],
                  V2 = 1:5)
df_2[3,] %>% as.numeric() # you expect to obtain c 3 but it returns
[1] 3 3
df_2[3,] %>% as.character() # this won't work neither
[1] "3" "3"

To prevent this behavior, you need to take care of the factor, before extracting it:

df_1$V1 = df_1$V1 %>% as.character() %>% as.numeric()
df_2$V1 = df_2$V1 %>% as.character()
df_1[1,] %>% as.numeric()
[1] 11  21
df_2[3,] %>% as.character()
[1] "c" "3"

Can't you just use string formatting of the value before you concat the filename?

"%03d" % number

I stumbled upon the same problem: a page with many independent animations, each one with its own parameters, which must be repeated forever.

Merging this clue with this other clue I found an easy solution: after the end of all your animations the wrapping div is restored, forcing the animations to restart.

All you have to do is to add these few lines of Javascript, so easy they don't even need any external library, in the <head> section of your page:

<script>
setInterval(function(){
var container = document.getElementById('content');
var tmp = container.innerHTML;
container.innerHTML= tmp;
}, 35000 // length of the whole show in milliseconds
);
</script>

BTW, the closing </head> in your code is misplaced: it must be before the starting <body>.

Short answer:

git reset 'HEAD@{1}'

Long answer:

Git keeps a log of all ref updates (e.g., checkout, reset, commit, merge). You can view it by typing:

git reflog

Somewhere in this list is the commit that you lost. Let's say you just typed git reset HEAD~ and want to undo it. My reflog looks like this:

$ git reflog
3f6db14 HEAD@{0}: HEAD~: updating HEAD
d27924e HEAD@{1}: checkout: moving from d27924e0fe16776f0d0f1ee2933a0334a4787b4c
[...]

The first line says that HEAD 0 positions ago (in other words, the current position) is 3f6db14; it was obtained by resetting to HEAD~. The second line says that HEAD 1 position ago (in other words, the state before the reset) is d27924e. It was obtained by checking out a particular commit (though that's not important right now). So, to undo the reset, run git reset HEAD@{1} (or git reset d27924e).

If, on the other hand, you've run some other commands since then that update HEAD, the commit you want won't be at the top of the list, and you'll need to search through the reflog.

One final note: It may be easier to look at the reflog for the specific branch you want to un-reset, say master, rather than HEAD:

$ git reflog show master
c24138b master@{0}: merge origin/master: Fast-forward
90a2bf9 master@{1}: merge origin/master: Fast-forward
[...]

This should have less noise it in than the general HEAD reflog.

JSTL 1.2 variation leveraged from BalusC answer

<c:set var="baseURL" value="${pageContext.request.requestURL.substring(0, pageContext.request.requestURL.length() - pageContext.request.requestURI.length())}${pageContext.request.contextPath}/" />

<head>
  <base href="${baseURL}" />

You could use the same mechanism the XAML reading system uses: Type converters

var converter = new System.Windows.Media.BrushConverter();
var brush = (Brush)converter.ConvertFromString("#FFFFFF90");
Fill = brush;

If you control the remote server, you should probably use CORS, as described in this answer; it's supported in IE8 and up, and all recent versions of FF, GC, and Safari. (But in IE8 and 9, CORS won't allow you to send cookies in the request.)

So, if you don't control the remote server, or if you have to support IE7, or if you need cookies and you have to support IE8/9, you'll probably want to use an iframe technique.

1. Create an iframe with a unique name. (iframes use a global namespace for the entire browser, so pick a name that no other website will use.)
2. Construct a form with hidden inputs, targeting the iframe.
3. Submit the form.

Here's sample code; I tested it on IE6, IE7, IE8, IE9, FF4, GC11, S5.

function crossDomainPost() {
  // Add the iframe with a unique name
  var iframe = document.createElement("iframe");
  var uniqueString = "CHANGE_THIS_TO_SOME_UNIQUE_STRING";
  document.body.appendChild(iframe);
  iframe.style.display = "none";
  iframe.contentWindow.name = uniqueString;

  // construct a form with hidden inputs, targeting the iframe
  var form = document.createElement("form");
  form.target = uniqueString;
  form.action = "http://INSERT_YOUR_URL_HERE";
  form.method = "POST";

  // repeat for each parameter
  var input = document.createElement("input");
  input.type = "hidden";
  input.name = "INSERT_YOUR_PARAMETER_NAME_HERE";
  input.value = "INSERT_YOUR_PARAMETER_VALUE_HERE";
  form.appendChild(input);

  document.body.appendChild(form);
  form.submit();
}

Beware! You won't be able to directly read the response of the POST, since the iframe exists on a separate domain. Frames aren't allowed to communicate with each other from different domains; this is the same-origin policy.

If you control the remote server but you can't use CORS (e.g. because you're on IE8/IE9 and you need to use cookies), there are ways to work around the same-origin policy, for example by using window.postMessage and/or one of a number of libraries allowing you to send cross-domain cross-frame messages in older browsers:

• Porthole
• XSSInterface
• EasyXDM
• jQuery PostMessage Plugin

If you don't control the remote server, then you can't read the response of the POST, period. It would cause security problems otherwise.

Shorter version of previous using map() function (works for python 2.7):

"".join(map(chr, myList))

Change = to == i.e if (strcmp("hello", "hello") == 0)

You want to compare the result of strcmp() to 0. So you need ==. Assigning it to 0 won't work because rvalues cannot be assigned to.

Well one way to do it is set the height of your body to the height that you want your page to be. In this example I did 600px.

Then set your wrapper height to a percentage of the body here I did 70% This will adjust your table so that it does not fill up the whole screen but in stead just takes up a percentage of the specified page height.

body {
   padding-top: 70px;
   border:1px solid black;
   height:600px;
}

.mygrid-wrapper-div {
   border: solid red 5px;
   overflow: scroll;
   height: 70%;
}

http://jsfiddle.net/4NB2N/7/

Update How about a jQuery approach.

$(function() {  
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

$( window ).resize(function() {
   var window_height = $(window).height(),
   content_height = window_height - 200;
   $('.mygrid-wrapper-div').height(content_height);
});

As short as @jumbo's answer is :-) you can do it even more tersely. This just returns the Count property of the array returned by the antecedent sub-expression:

@(Get-Alias).Count

A couple points to note:

1. You can put an arbitrarily complex expression in place of Get-Alias, for example:

   @(Get-Process | ? { $_.ProcessName -eq "svchost" }).Count
   

2. The initial at-sign (@) is necessary for a robust solution. As long as the answer is two or greater you will get an equivalent answer with or without the @, but when the answer is zero or one you will get no output unless you have the @ sign! (It forces the Count property to exist by forcing the output to be an array.)

2012.01.30 Update

The above is true for PowerShell V2. One of the new features of PowerShell V3 is that you do have a Count property even for singletons, so the at-sign becomes unimportant for this scenario.

One way is to add your shortcut keys to the commands themselves them as InputGestures. Commands are implemented as RoutedCommands.

This enables the shortcut keys to work even if they're not hooked up to any controls. And since menu items understand keyboard gestures, they'll automatically display your shortcut key in the menu items text, if you hook that command up to your menu item.

1. Create static attribute to hold a command (preferably as a property in a static class you create for commands - but for a simple example, just using a static attribute in window.cs):

    public static RoutedCommand MyCommand = new RoutedCommand();
   

2. Add the shortcut key(s) that should invoke method:

    MyCommand.InputGestures.Add(new KeyGesture(Key.S, ModifierKeys.Control));
   

3. Create a command binding that points to your method to call on execute. Put these in the command bindings for the UI element under which it should work for (e.g., the window) and the method:

    <Window.CommandBindings>
        <CommandBinding Command="{x:Static local:MyWindow.MyCommand}" Executed="MyCommandExecuted"/>
    </Window.CommandBindings>
   
    private void MyCommandExecuted(object sender, ExecutedRoutedEventArgs e) { ... }
   

The right way to do this is:

composer remove jenssegers/mongodb --update-with-dependencies

I must admit the flag here is not quite obvious as to what it will do.

Update

composer remove jenssegers/mongodb

As of v1.0.0-beta2 --update-with-dependencies is the default and is no longer required.

SELECT p.MEMBSHIP_ID
FROM user_payments as p
WHERE USER_ID = 1 AND PAYM_DATE = (
    SELECT MAX(p2.PAYM_DATE)
    FROM user_payments as p2
    WHERE p2.USER_ID = p.USER_ID
)

It is just a matter of using text indentation in the query editor.

Expanded View:

Collapsed View:

I found solution. It works fine when I throw away next line from form:

enctype="multipart/form-data"

And now it pass all parameters at request ok:

 <form action="/registration" method="post">
   <%-- error messages --%>
   <div class="form-group">
    <c:forEach items="${registrationErrors}" var="error">
    <p class="error">${error}</p>
     </c:forEach>
   </div>

Another solution I found was this, if you have multiple classes and are dealing with radio buttons while clicking on the label.

$('.btn').on('click', function(e) {
    e.preventDefault();

    // Hack - Stop Double click on Radio Buttons
    if (e.target.tagName != 'INPUT') {
        // Not a input, check to see if we have a radio
        $(this).find('input').attr('checked', 'checked').change();
    }
});

The colon is a built-in command that does nothing, but returns 0 (success). Thus, it's shorter (and faster) than calling an actual command to do the same thing.

The above solutions didn't work for me. Here is what I finally came up with:

$( "#ddl" ).find( "option:selected" ).text();           // Text
$( "#ddl" ).find( "option:selected" ).prop("value");    // Value

If you want to retain the exact commit history of the second repository and therefore also retain the ability to easily merge upstream changes in the future then here is the method you want. It results in unmodified history of the subtree being imported into your repo plus one merge commit to move the merged repository to the subdirectory.

git remote add XXX_remote <path-or-url-to-XXX-repo>
git fetch XXX_remote
git merge -s ours --no-commit --allow-unrelated-histories XXX_remote/master
git read-tree --prefix=ZZZ/ -u XXX_remote/master
git commit -m "Imported XXX as a subtree."

You can track upstream changes like so:

git pull -s subtree XXX_remote master

Git figures out on its own where the roots are before doing the merge, so you don't need to specify the prefix on subsequent merges.

The downside is that in the merged history the files are unprefixed (not in a subdirectory). As a result git log ZZZ/a will show you all the changes (if any) except those in the merged history. You can do:

git log --follow -- a

but that won't show the changes other then in the merged history.

In other words, if you don't change ZZZ's files in repository XXX, then you need to specify --follow and an unprefixed path. If you change them in both repositories, then you have 2 commands, none of which shows all the changes.

Git versions before 2.9: You don’t need to pass the --allow-unrelated-histories option to git merge.

The method in the other answer that uses read-tree and skips the merge -s ours step is effectively no different than copying the files with cp and committing the result.

Original source was from github's "Subtree Merge" help article. And another useful link.

Well there is no direct method to do it You can consider some workarounds.

1. Change and increase the frame and add bordercolor as you did
2. Add a view behind the current view with the larger size so that it appears as border.Can be worked as a custom class of view

3. If you dont need a definite border (clearcut border) then you can depend on shadow for the purpose

   [view1 setBackgroundColor:[UIColor blackColor]];
   UIColor *color = [UIColor yellowColor];
   view1.layer.shadowColor = [color CGColor];
   view1.layer.shadowRadius = 10.0f;
   view1.layer.shadowOpacity = 1;
   view1.layer.shadowOffset = CGSizeZero;
   view1.layer.masksToBounds = NO;
   

You would have to unbind the event and either rebind to a separate event that does not preventDefault or just call the default event yourself later in the method after unbinding. There is no magical event.cancelled=false;

As requested

 $('form').submit( function(ev){

         ev.preventDefault();

         //later you decide you want to submit
         $(this).unbind('submit').submit()

  });

They seem to continuously change stuff in Chrome, but here's what works right now :-)

• First you must click on the red record button or you'll get nothing.

• I never noticed the WS before but it filters out the web socket connections.

• Select it and then you can see the Frames (now called Messages) which will show you error messages etc.

Adding where to find UPDATE CURRENT_TIMESTAMP because for new people this is a confusion.

Most people will use phpmyadmin or something like it.

Default value you select CURRENT_TIMESTAMP

Attributes (a different drop down) you select UPDATE CURRENT_TIMESTAMP

You don't need the div's.

Working syntax for multiple optional params:

<Route path="/section/(page)?/:page?/(sort)?/:sort?" component={Section} />

Now, url can be:

1. /section
2. /section/page/1
3. /section/page/1/sort/asc

<style>
.left-column
{
float:left;
width:30%;
background-color:red;
}
.right-column

}
.center-column

<div id="container">
<section class="left-column">THIS IS COLUMN 1 LEFT</section>
<section class="right-column">THIS IS COLUMN 3 RIGHT</section>
<section class="center-column">THIS IS COLUMN 2 CENTER</section>
</div>

the advantage of this way is you can set each column width independant of the other as long as you keep it under 100%, if you use 3 x 30% the remaining 10% is split as a 5% divider space between the collumns

One option is to use Python's slicing and indexing features to logically evaluate the places where your condition holds and overwrite the data there.

Assuming you can load your data directly into pandas with pandas.read_csv then the following code might be helpful for you.

import pandas
df = pandas.read_csv("test.csv")
df.loc[df.ID == 103, 'FirstName'] = "Matt"
df.loc[df.ID == 103, 'LastName'] = "Jones"

As mentioned in the comments, you can also do the assignment to both columns in one shot:

df.loc[df.ID == 103, ['FirstName', 'LastName']] = 'Matt', 'Jones'

Note that you'll need pandas version 0.11 or newer to make use of loc for overwrite assignment operations.

Another way to do it is to use what is called chained assignment. The behavior of this is less stable and so it is not considered the best solution (it is explicitly discouraged in the docs), but it is useful to know about:

import pandas
df = pandas.read_csv("test.csv")
df['FirstName'][df.ID == 103] = "Matt"
df['LastName'][df.ID == 103] = "Jones"

The procedure name should be in caps while creating procedure in database. You may use small letters for your procedure name while calling from Java class like:

String getDBUSERByUserIdSql = "{call getDBUSERByUserId(?,?,?,?)}";

In database the name of procedure should be:

GETDBUSERBYUSERID    -- (all letters in caps only)

This serves as one of the solutions for this problem.

The minimum length is 4 for Saint Helena (Format: +290 XXXX) and Niue (Format: +683 XXXX).

You can use the inbuilt function max() with multiple arguments:

print max(1, 2, 3)

or a list:

list = [1, 2, 3]
print max(list)

or in fact anything iterable.

If performance matters to you make sure you time:

import sys
import timeit
import pandas as pd

print('Python %s on %s' % (sys.version, sys.platform))
print('Pandas version %s' % pd.__version__)

repeat = 3
numbers = 100

def time(statement, _setup=None):
    print (min(
        timeit.Timer(statement, setup=_setup or setup).repeat(
            repeat, numbers)))

print("Format %m/%d/%y")
setup = """import pandas as pd

So with iso8601-formatted date (%Y-%m-%d %H:%M:%S is apparently an iso8601-formatted date, I guess the T can be dropped and replaced by a space) you should not specify infer_datetime_format (which does not make a difference with more common ones either apparently) and passing your own parser in just cripples performance. On the other hand, date_parser does make a difference with not so standard day formats. Be sure to time before you optimize, as usual.

In newer versions of CMake you can set compiler and linker flags for a single target with target_compile_options and target_link_libraries respectively (yes, the latter sets linker options too):

target_compile_options(first-test PRIVATE -fexceptions)

The advantage of this method is that you can control propagation of options to other targets that depend on this one via PUBLIC and PRIVATE.

As of CMake 3.13 you can also use target_link_options to add linker options which makes the intent more clear.

diff(1) is not the answer, but comm(1) is.

NAME
       comm - compare two sorted files line by line

SYNOPSIS
       comm [OPTION]... FILE1 FILE2

...

       -1     suppress lines unique to FILE1

       -2     suppress lines unique to FILE2

       -3     suppress lines that appear in both files

So

comm -2 -3 file1 file2 > file3

The input files must be sorted. If they are not, sort them first. This can be done with a temporary file, or...

comm -2 -3 <(sort file1) <(sort file2) > file3

provided that your shell supports process substitution (bash does).

You need the whole python package, with a setup.py file in it.

A package named foo would be:

foo # the installable package
+-- foo
¦   +-- __init__.py
¦   +-- bar.py
+-- setup.py

And install from github like:

$ pip install git+ssh://[email protected]/myuser/foo.git
or
$ pip install git+https://github.com/myuser/foo.git@v123
or
$ pip install git+https://github.com/myuser/foo.git@newbranch

Visual Studio 2005

1. Create a new console application project in Visual Studio
2. Add a "Web Reference" to the Lists.asmx web service.
   • Your URL will probably look like: http://servername/sites/SiteCollection/SubSite/_vti_bin/Lists.asmx
   • I named my web reference: ListsWebService
3. Write the code in program.cs (I have an Issues list here)

Here is the code.

using System;
using System.Collections.Generic;
using System.Text;
using System.Xml;

namespace WebServicesConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                ListsWebService.Lists listsWebSvc = new WebServicesConsoleApp.ListsWebService.Lists();
                listsWebSvc.Credentials = System.Net.CredentialCache.DefaultNetworkCredentials;
                listsWebSvc.Url = "http://servername/sites/SiteCollection/SubSite/_vti_bin/Lists.asmx";
                XmlNode node = listsWebSvc.GetList("Issues");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }
        }
    }
}

Visual Studio 2008

1. Create a new console application project in Visual Studio
2. Right click on References and Add Service Reference
3. Put in the URL to the Lists.asmx service on your server
   • Ex: http://servername/sites/SiteCollection/SubSite/_vti_bin/Lists.asmx
4. Click Go
5. Click OK
6. Make the following code changes:

Change your app.config file from:

<security mode="None">
    <transport clientCredentialType="None" proxyCredentialType="None"
        realm="" />
    <message clientCredentialType="UserName" algorithmSuite="Default" />
</security>

To:

<security mode="TransportCredentialOnly">
  <transport clientCredentialType="Ntlm"/>
</security>

Change your program.cs file and add the following code to your Main function:

ListsSoapClient client = new ListsSoapClient();
client.ClientCredentials.Windows.ClientCredential = System.Net.CredentialCache.DefaultNetworkCredentials;
client.ClientCredentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;
XmlElement listCollection = client.GetListCollection();

Add the using statements:

using [your app name].ServiceReference1;
using System.Xml;

It happened to me when I deployed my main.jar, without checking the add directory entries box in the export jar menu in Eclipse.

Add this to your ajax call:

contentType: "application/json; charset=utf-8",
dataType: "json"

If you were unfamiliar with the tools, it was likely that at some point while in the debugger you toggled a setting that was causing the debugger to stop the application.

I suggest you "Disable all break points":

You need a BroadcastReceiver for ACTION_PHONE_STATE_CHANGED This will call your received whenever the phone-state changes from idle, ringing, offhook so from the previous value and the new value you can detect if this is an incoming/outgoing call.

Required permission would be:

<uses-permission android:name="android.permission.READ_PHONE_STATE"/>

But if you also want to receive the EXTRA_INCOMING_NUMBER in that broadcast, you'll need another permission: "android.permission.READ_CALL_LOG"

And the code something like this:

val receiver: BroadcastReceiver = object : BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        Log.d(TAG, "onReceive")
    }
}

override fun onResume() {
    val filter = IntentFilter()
    filter.addAction("android.intent.action.PHONE_STATE")
    registerReceiver(receiver, filter)
    super.onResume()
}

override fun onPause() {
    unregisterReceiver(receiver)
    super.onPause()
}

and in receiver class, we can get current state by reading intent like this:

intent.extras["state"]

the result of extras could be:

RINGING -> If your phone is ringing

OFFHOOK -> If you are talking with someone (Incoming or Outcoming call)

IDLE -> if call ended (Incoming or Outcoming call)

With PHONE_STATE broadcast we don't need to use PROCESS_OUTGOING_CALLS permission or deprecated NEW_OUTGOING_CALL action.

For the love of all that is holy...

In my case, I had to set the openssl.cafile PHP config variable to the PEM file path.

I trust it is very true that there are many systems where setting curl.cainfo in PHP's config is exactly what is needed, but in the environment I'm working with, which is the eboraas/laravel docker container, which uses Debian 8 (jessie) and PHP 5.6, setting that variable did not do the trick.

I noticed that the output of php -i did not mention anything about that particular config setting, but it did have a few lines about openssl. There is both an openssl.capath and openssl.cafile option, but just setting the second one allowed curl via PHP to finally be okay with HTTPS URLs.
