If AddDbContext is used, then also ensure that your DbContext type accepts a DbContextOptions object in its constructor and passes it to the base constructor for DbContext.

The error message says your DbContext(LogManagerContext ) needs a constructor which accepts a DbContextOptions. But i couldn't find such a constructor in your DbContext. So adding below constructor probably solves your problem.

    public LogManagerContext(DbContextOptions options) : base(options)
    {
    }

Edit for comment

If you don't register IHttpContextAccessor explicitly, use below code:

services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>(); 

This is an alternative if you don't want to use claims all the time. Take a look at this tutorial by Ben Foster.

public class AppUser : ClaimsPrincipal
{
    public AppUser(ClaimsPrincipal principal)
        : base(principal)
    {
    }

    public string Name
    {
        get
        {
            return this.FindFirst(ClaimTypes.Name).Value;
        } 
    }

}

Then you can add a base controller.

public abstract class AppController : Controller
{       
    public AppUser CurrentUser
    {
        get
        {
            return new AppUser(this.User as ClaimsPrincipal);
        }
    }
}

In you controller, you would do:

public class HomeController : AppController
{
    public ActionResult Index()
    {
        ViewBag.Name = CurrentUser.Name;
        return View();
    }
}

Thanks for all the replies.

I was able to solve this by doing the following:

CONTROLLER:

[HttpPost]       
public ActionResult form_edit(FormModels model)
{
  model.error_msg = model.update_content(model);
  return RedirectToAction("Form_edit", "Form", model);
}

public ActionResult form_edit(FormModels model, string searchString,string id)
{
  string test = model.selectedvalue;
  var bal = new FormModels();
  bal.Countries = bal.get_contentdetails(searchString);
  bal.selectedvalue = id;
  bal.dd_text = "content_name";
  bal.dd_value = "content_id";

  test = model.error_msg;
  ViewBag.head = "Heading";

  if (model.error_msg != null)
  {
    ModelState.AddModelError("error_msg", test);
  }

  model.error_msg = "";
  return View(bal);
}   

VIEW:

@using (Html.BeginForm("form_edit", "Form", FormMethod.Post))
{
  <table>
    <tr>
      <td>
        @ViewBag.error
        @Html.ValidationMessage("error_msg")
      </td>
    </tr>
    <tr>
      <th>
        @Html.DisplayNameFor(model => model.content_name)
        @Html.DropDownListFor(x => x.selectedvalue, new SelectList(Model.Countries, Model.dd_value, Model.dd_text), "-- Select Product--")
      </th>
    </tr>
  </table>
}

Try the following in your view to check the output from each. The first one updates when the view is called a second time. My controller uses the key ShowCreateButton and has the optional parameter _createAction with a default value - you can change this to your key/parameter

@Html.TextBox("_createAction", null, new { Value = (string)ViewBag.ShowCreateButton })
@Html.TextBox("_createAction", ViewBag.ShowCreateButton )
@ViewBag.ShowCreateButton

I eventually stumbled upon an example of the usage I was looking for - to assign an error to the Model in general, rather than one of it's properties, as usual you call:

ModelState.AddModelError(string key, string errorMessage);

but use an empty string for the key:

ModelState.AddModelError(string.Empty, "There is something wrong with Foo.");

The error message will present itself in the <%: Html.ValidationSummary() %> as you'd expect.

You can try,

<div asp-validation-summary="All" class="text-danger"></div>

Not sure about "Best Practices" for memory leaks in python, but python should clear it's own memory by it's garbage collector. So mainly I would start by checking for circular list of some short, since they won't be picked up by the garbage collector.

If you want to loop over a range and do something for every number that is NOT a perfect square, you could do something like this:

def non_squares(upper):
    next_square = 0
    diff = 1
    for i in range(0, upper):
        if i == next_square:
            next_square += diff
            diff += 2
            continue
        yield i

If you want to do something for every number that IS a perfect square, the generator is even easier:

(n * n for n in range(upper))

If you are uploading your files through GIT from your local machine then you can use the same command you are using in your local machine while you are connected to your live server using BASH or something like.You can use this as like you use locally.

php artisan cache:clear

php artisan route:cache

It should work.

Typically, you'd use a built-in layout control appropriate for your scenario (e.g. use a grid as a parent if you want scaling relative to the parent). If you want to do it with an arbitrary parent element, you can create a ValueConverter do it, but it probably won't be quite as clean as you'd like. However, if you absolutely need it, you could do something like this:

public class PercentageConverter : IValueConverter
{
    public object Convert(object value, 
        Type targetType, 
        object parameter, 
        System.Globalization.CultureInfo culture)
    {
        return System.Convert.ToDouble(value) * 
               System.Convert.ToDouble(parameter);
    }

    public object ConvertBack(object value, 
        Type targetType, 
        object parameter, 
        System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }
}

Which can be used like this, to get a child textbox 10% of the width of its parent canvas:

<Window x:Class="WpfApplication1.Window1"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:WpfApplication1"
    Title="Window1" Height="300" Width="300">
    <Window.Resources>
        <local:PercentageConverter x:Key="PercentageConverter"/>
    </Window.Resources>
    <Canvas x:Name="canvas">
        <TextBlock Text="Hello"
                   Background="Red" 
                   Width="{Binding 
                       Converter={StaticResource PercentageConverter}, 
                       ElementName=canvas, 
                       Path=ActualWidth, 
                       ConverterParameter=0.1}"/>
    </Canvas>
</Window>

You could use a temp table which the stored procedure expects to exist. This will work on older versions of SQL Server, which do not support XML etc.

CREATE TABLE #temp
(INT myid)
GO
CREATE PROC myproc
AS
BEGIN
    DELETE YourTable
    FROM YourTable                    
    LEFT OUTER JOIN #temp T ON T.myid=s.id
    WHERE s.id IS NULL
END

If you have a Floating Action Button with no drawable you can change the tint programmatically using:

fab.getBackground().mutate().setTint(ContextCompat.getColor(yourContext, R.color.anyColor));

You must have the definition of class B before you use the class. How else would the compiler otherwise know that there exists such a function as B::add?

Either define class B before class A, or move the body of A::doSomething to after class B have been defined, like

class B;

class A
{
    B* b;

    void doSomething();
};

class B
{
    A* a;

    void add() {}
};

void A::doSomething()
{
    b->add();
}

It is possible to print what Python lines are executed (thanks Geo!). This has any number of applications, for example, you could modify it to check when particular functions are called or add something like ## make it only track particular lines.

code.interact takes you into a interactive console

import code; code.interact(local=locals())

If you want to be able to easily access your console history look at: "Can I have a history mechanism like in the shell?" (will have to look down for it).

Auto-complete can be enabled for the interpreter.

The root of the problem is that Spring (via ResponseEntity, RestController, and/or ResponseBody) will use the contents of the string as the raw response value, rather than treating the string as JSON value to be encoded. This is true even when the controller method uses produces = MediaType.APPLICATION_JSON_VALUE, as in the question here.

It's essentially like the difference between the following:

// yields: This is a String
System.out.println("This is a String");

// yields: "This is a String"
System.out.println("\"This is a String\"");

The first output cannot be parsed as JSON, but the second output can.

Something like '"'+myString+'"' is probably not a good idea however, as that won't handle proper escaping of double-quotes within the string and will not produce valid JSON for any such string.

One way to handle this would be to embed your string inside an object or list, so that you're not passing a raw string to Spring. However, that changes the format of your output, and really there's no good reason not to be able to return a properly-encoded JSON string if that's what you want to do. If that's what you want, the best way to handle it is via a JSON formatter such as Json or Google Gson. Here's how it might look with Gson:

import com.google.gson.Gson;

@RestController
public class MyController

    private static final Gson gson = new Gson();

    @RequestMapping(value = "so", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    ResponseEntity<String> so() {
        return ResponseEntity.ok(gson.toJson("This is a String"));
    }
}

Well .. just for the sake of saving a headache (its past midnight here), I could come up with:

$('#checkbox1').click(function() {
  if (!$(this).is(':checked')) {
    var ans = confirm("Are you sure?");
     $('#textbox1').val(ans);
  }
});

Hope it helps

You could try something like this in javascript:
var regex = /[^a-zA-Z]/g;

and have a keyup event.
$("#nameofInputbox").value.replace(regex, "");

The new version of this should read like so:

xcrun g++ hw.cpp
./a.out

you need to put a dot between the class like

class="column.wrapper">

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

The main purpose of a list comprehension is to create a new list based on another one without changing or destroying the original list.

Instead of writing

l = []
for n in range(1, 11):
    l.append(n)

or

l = [n for n in range(1, 11)]

you should write only

l = range(1, 11)

In the two top code blocks you're creating a new list, iterating through it and just returning each element. It's just an expensive way of creating a list copy.

To get a new dictionary with all keys set to the same value based on another dict, do this:

old_dict = {'a': 1, 'c': 3, 'b': 2}
new_dict = { key:'your value here' for key in old_dict.keys()}

You're receiving a SyntaxError because when you write

d = {}
d[i for i in range(1, 11)] = True

you're basically saying: "Set my key 'i for i in range(1, 11)' to True" and "i for i in range(1, 11)" is not a valid key, it's just a syntax error. If dicts supported lists as keys, you would do something like

d[[i for i in range(1, 11)]] = True

and not

d[i for i in range(1, 11)] = True

but lists are not hashable, so you can't use them as dict keys.

Hex-Rays decompiler is probably the best in this field !!!

Use MySQL's STR_TO_DATE() function to parse the string that you're attempting to insert:

INSERT INTO tblInquiry (fldInquiryReceivedDateTime) VALUES
  (STR_TO_DATE('5/15/2012 8:06:26 AM', '%c/%e/%Y %r'))

There's an IEC standard that distinguishes the terms, e.g. Mebibyte = 1024^2 bytes but Megabyte = 1000^2 (in order to be compatible to SI units like kilograms where k/M/... means 1000/1000000). Actually most people in the IT area will prefer Megabyte = 1024^2 and hard disk manufacturers will prefer Megabyte = 1000^2 (because hard disk sizes will sound bigger than they are).

As a matter of fact, most people are confused by the IEC standard (multiplier 1000) and the traditional meaning (multiplier 1024). In general you shouldn't make assumptions on what people mean. For example, 128 kBit/s for MP3s usually means 128000 bits because the multiplier 1000 is mostly used with the unit bits. But often people then call 2048 kBit/s equal to 2 MBit/s - confusing eh?

So as a general rule, don't trust bit/byte units at all ;)

An easier way would be to:

git checkout --theirs /path/to/file.extension
git pull origin master

This will override your local file with the file on git

Read this article, it will help you.

Here's a very simple bounding rectangle routine. It expects both a and b to be objects with x, y, width and height properties:

function isCollide(a, b) {
    return !(
        ((a.y + a.height) < (b.y)) ||
        (a.y > (b.y + b.height)) ||
        ((a.x + a.width) < b.x) ||
        (a.x > (b.x + b.width))
    );
}

To see this function in action, here's a codepen graciously made by @MixerOID.

I think that MySql and MsSql won't allow this because they will try to find all columns in the CASE clause as columns of the tables in the WHERE clause.

I don't know what DBMS you are talking about, but I guess you could do something like this in any DBMS:

SELECT *, CASE WHEN a = 'test' THEN 'yes' END as value FROM (
   SELECT col1 as a FROM table
) q

Think about somebody doing help(yourmodule) at the interactive interpreter's prompt — what do they want to know? (Other methods of extracting and displaying the information are roughly equivalent to help in terms of amount of information). So if you have in x.py:

"""This module does blah blah."""

class Blah(object):
  """This class does blah blah."""

then:

>>> import x; help(x)

shows:

Help on module x:

NAME
    x - This module does blah blah.

FILE
    /tmp/x.py

CLASSES
    __builtin__.object
        Blah

    class Blah(__builtin__.object)
     |  This class does blah blah.
     |  
     |  Data and other attributes defined here:
     |  
     |  __dict__ = <dictproxy object>
     |      dictionary for instance variables (if defined)
     |  
     |  __weakref__ = <attribute '__weakref__' of 'Blah' objects>
     |      list of weak references to the object (if defined)

As you see, the detailed information on the classes (and functions too, though I'm not showing one here) is already included from those components' docstrings; the module's own docstring should describe them very summarily (if at all) and rather concentrate on a concise summary of what the module as a whole can do for you, ideally with some doctested examples (just like functions and classes ideally should have doctested examples in their docstrings).

I don't see how metadata such as author name and copyright / license helps the module's user — it can rather go in comments, since it could help somebody considering whether or not to reuse or modify the module.

const absolutePath = path.join(__dirname, some, dir);

vs.

const absolutePath = path.resolve(__dirname, some, dir);

path.join will concatenate __dirname which is the directory name of the current file concatenated with values of some and dir with platform-specific separator.

Whereas

path.resolve will process __dirname, some and dir i.e. from right to left prepending it by processing it.

If any of the values of some or dir corresponds to a root path then the previous path will be omitted and process rest by considering it as root

In order to better understand the concept let me explain both a little bit more detail as follows:-

The path.join and path.resolve are two different methods or functions of the path module provided by nodejs.

Where both accept a list of paths but the difference comes in the result i.e. how they process these paths.

path.join concatenates all given path segments together using the platform-specific separator as a delimiter, then normalizes the resulting path. While the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

When no arguments supplied

The following example will help you to clearly understand both concepts:-

My filename is index.js and the current working directory is E:\MyFolder\Pjtz\node

const path = require('path');

console.log("path.join() : ", path.join());
// outputs .
console.log("path.resolve() : ", path.resolve());
// outputs current directory or equivalent to __dirname

Result

? node index.js
path.join() :  .
path.resolve() :  E:\MyFolder\Pjtz\node

path.resolve() method will output the absolute path whereas the path.join() returns . representing the current working directory if nothing is provided

When some root path is passed as arguments

const path=require('path');

console.log("path.join() : " ,path.join('abc','/bcd'));
console.log("path.resolve() : ",path.resolve('abc','/bcd'));

Result i

? node index.js
path.join() :  abc\bcd
path.resolve() :  E:\bcd

path.join() only concatenates the input list with platform-specific separator while the path.resolve() process the sequence of paths from right to left, with each subsequent path prepended until an absolute path is constructed.

Your Maven project doesn't seem to be configured as a Eclipse Java project, that is the Java nature is missing (the little 'J' in the project icon).

To enable this, the <packaging> element in your pom.xml should be jar (or similar).

Then, right-click the project and select Maven > Update Project Configuration

For this to work, you need to have m2eclipse installed. But since you had the _ New ... > New Maven Project_ wizard, I assume you have m2eclipse installed.

The only thing you have to do is adding this line to your sketch

#include <SPI.h>

before #include <Adafruit_MAX31855.h>.

Here are two ways "IF" Or "CASE".

SELECT IF(COLUMN_NAME = "VALUE", "VALUE_1", "VALUE_2") AS COLUMN_NAME 
FROM TABLE_NAME;

OR

SELECT (CASE WHEN COLUMN_NAME = "VALUE" THEN 'VALUE_1' ELSE 'VALUE_2' END) AS COLUMN_NAME 
FROM TABLE_NAME;

Only second approach will work. You can modify collection during iteration using iterator.remove() only. All other attempts will cause ConcurrentModificationException.

You also can use StringUtils.isNoneEmpty("") for check is null or empty.

Use [Dispatcher.Invoke(DispatcherPriority, Delegate)] to change the UI from another thread or from background.

Step 1. Use the following namespaces

using System.Windows;
using System.Threading;
using System.Windows.Threading;

Step 2. Put the following line where you need to update UI

Application.Current.Dispatcher.Invoke(DispatcherPriority.Background, new ThreadStart(delegate
{
    //Update UI here
}));

Syntax

[BrowsableAttribute(false)]
public object Invoke(
  DispatcherPriority priority,
  Delegate method
)

Parameters

priority

Type: System.Windows.Threading.DispatcherPriority

The priority, relative to the other pending operations in the Dispatcher event queue, the specified method is invoked.

method

Type: System.Delegate

A delegate to a method that takes no arguments, which is pushed onto the Dispatcher event queue.

Return Value

Type: System.Object

The return value from the delegate being invoked or null if the delegate has no return value.

I'm starting to learn about this myself, being very new to android development and I found this video very helpful.

https://www.youtube.com/watch?v=qcotbMLjlA4

It specifically covers to to get JSONArray to JSONObject at 19:30 in the video.

Code from the video for JSONArray to JSONObject:

JSONArray queryArray = quoteJSONObject.names();

ArrayList<String> list = new ArrayList<String>();

for(int i = 0; i < queryArray.length(); i++){
    list.add(queryArray.getString(i));
}

for(String item : list){
    Log.v("JSON ARRAY ITEMS ", item);
}

There's an array that gives you the exit status of each command in a pipe.

$ cat x| sed 's///'
cat: x: No such file or directory
$ echo $?
0
$ cat x| sed 's///'
cat: x: No such file or directory
$ echo ${PIPESTATUS[*]}
1 0
$ touch x
$ cat x| sed 's'
sed: 1: "s": substitute pattern can not be delimited by newline or backslash
$ echo ${PIPESTATUS[*]}
0 1

This happens to me once: I uninstalled the IIS, and the port 80 still was used. Well the problem was that also I had the Report Service of the Sql Server 2012 installed, so I stopped that service and the problems solves.

See Stop Or Uninstall IIS for running Wamp Server (Apache) on default port (:80) question for more details.

Hope this helps some body, as it help to me.

you can store it in a data attribute.

$('.colapsable').each(function(){
    $(this).attr('data-oheight',$(this).height());
    $(this).height(100);
});

$('.colapsable h2:first-child').click(function(){
    $(this).parent('.colapsable').animate({
            height: $(this).parent('.colapsible').data('oheight')
        },500);
    }
});

I presume it is referring to Tools > Android > "Sync Project with Gradle Files" from the Android Studio main menu.

One approach (which I can't imagine is good programming practice) is to add the ... which is traditionally used to pass arguments specified in one function to another.

> multiply <- function(a,b) a*b
> multiply(a = 2,b = 4,c = 8)
Error in multiply(a = 2, b = 4, c = 8) : unused argument(s) (c = 8)
> multiply2 <- function(a,b,...) a*b
> multiply2(a = 2,b = 4,c = 8)
[1] 8

Other answers are correct, especially the one by Jon Skeet, but outdated.

java.time

These old date-time classes have been supplanted by the java.time framework built into Java 8 and later.

If you simply want the current time in UTC, use the Instant class.

Instant now = Instant.now();

EST is not a time zone, as explained in the correct Answer by Jon Skeet. Such 3-4 letter codes are neither standardized nor unique, and further the confusion over Daylight Saving Time (DST). Use a proper time zone name in the "continent/region" format.

Perhaps you meant Eastern Standard Time in east coast of north America? Or Egypt Standard Time? Or European Standard Time?

ZoneId zoneId = ZoneId.of( "America/New_York" );
ZoneId zoneId = ZoneId.of( "Africa/Cairo" );
ZoneId zoneId = ZoneId.of( "Europe/Lisbon" );

Use any such ZoneId object to get the current moment adjusted to a particular time zone to produce a ZonedDateTime object.

ZonedDateTime zdt = ZonedDateTime.now( zoneId ) ;

Adjust that ZonedDateTime into a different time zone by producing another ZonedDateTime object from the first. The java.time framework uses immutable objects rather than changing (mutating) existing objects.

ZonedDateTime zdtGuam = zdt.withZoneSameInstant( ZoneId.of( "Pacific/Guam" ) ) ;

You can only do this to you own photos. Due to recent upgrades, Facebook has made this more difficult. To do this, go to the album page where the photo is that you want to link to. You should see thumbnail images of the photos in the album. Hold down the "Control" or "Command" key while clicking the photo that you wish to link to. A new browser tab will open with the picture you clicked. Under the picture there is a URL that you can send to others to share the photo. You might have to have the privacy settings for that album set so that anyone can see the photos in that album. If you don't the person who clicks the link may have to be signed in and also be your "friend."

Here is an example of one of my photos: http://www.facebook.com/photo.php?pid=43764341&l=0d8a526a64&id=25502298 -it's my cat.

Update:

The link below the photo no longer appears. Once you open the photo in a new tab you can right click the photo (Control+click for Mac users) and click "Copy Image URL" or similar and then share this link. Based on my tests the person who clicks the link doesn't need to use Facebook. The photo will load without the Facebook interface. Like this - http://a1.sphotos.ak.fbcdn.net/hphotos-ak-ash4/189088_867367406856_25502298_43764341_1304758_n.jpg

This post is high up when you google that error message, which I got when installing security patch KB4505224 on SQL Server 2017 Express i.e. None of the above worked for me, but did consume several hours trying.

The solution for me, partly from here was:

1. uninstall SQL Server
2. in Regional Settings / Management / System Locale, "Beta: UTF-8 support" should be OFF
3. re-install SQL Server
4. Let Windows install the patch.

And all was well.

More on this here.

There are several issues:

1. Class names (and IDs) are not allowed to start with a digit.
2. You have to pass a class to getElementsByClassName().
3. You have to iterate of the result set.

Example (untested):

<script type="text/javascript">
function hideTd(className){
    var elements = document.getElementsByClassName(className);
    for(var i = 0, length = elements.length; i < length; i++) {
       if( elements[i].textContent == ''){
          elements[i].style.display = 'none';
       } 
    }

  }
</script>
</head>
<body onload="hideTd('td');">
<table border="1">
  <tr>
    <td class="td">not empty</td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
  <tr>
    <td class="td"></td>
  </tr>
</table>
</body>

Note that getElementsByClassName() is not available up to and including IE8.

Update:

Alternatively you can give the table an ID and use:

var elements = document.getElementById('tableID').getElementsByTagName('td');

to get all td elements.

To hide the parent row, use the parentNode property of the element:

elements[i].parentNode.style.display = "none";

try {
    Import-Module SomeModule
    Write-Host "Module exists"
} 
catch {
    Write-Host "Module does not exist"
}

It should be pointed out that your cmdlet Import-Module has no terminating error, therefore the exception isnt being caught so no matter what your catch statement will never return the new statement you have written.

(https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/about/about_try_catch_finally?view=powershell-6

From The Above:

"A terminating error stops a statement from running. If PowerShell does not handle a terminating error in some way, PowerShell also stops running the function or script using the current pipeline. In other languages, such as C#, terminating errors are referred to as exceptions. For more information about errors, see about_Errors."

It should be written as:

Try {
    Import-Module SomeModule -Force -Erroraction stop
    Write-Host "yep"
}
Catch {
    Write-Host "nope"
}

Which returns:

nope

And if you really wanted to be thorough you should add in the other suggested cmdlets Get-Module -ListAvailable -Name and Get-Module -Name to be extra cautious, before running other functions/cmdlets. And if its installed from psgallery or elsewhere you could also run a Find-Module cmdlet to see if there is a new version available.

Your problem is probably that a elements are display: inline by nature. You can't set the width and height of inline elements.

You would have to set display: block on the a, but that will bring other problems because the links start behaving like block elements. The most common cure to that is giving them float: left so they line up side by side anyway.

You should try with the parent elements;

html, body, form, main {
    height: 100%;
}

Then this will be enough :

#s7 {
   height: 100%;
}

The packages you installed introduced dependencies to version 5.2.3.0 dll's as user Bracher showed above. Microsoft.AspNet.WebApi.Cors is an example package. The path I take is to update the MVC project proir to any package installs:

Install-Package Microsoft.AspNet.Mvc -Version 5.2.3

https://www.nuget.org/packages/microsoft.aspnet.mvc

You need to specify the format:

DateTime date = DateTime.ParseExact(
    "Tue, 1 Jan 2008 00:00:00 UTC", 
    "ddd, d MMM yyyy HH:mm:ss UTC", 
    CultureInfo.InvariantCulture);

simply put a dot next to it

git clone [email protected]:user/my-project.git .

From git help clone:

Cloning into an existing directory is only allowed if the directory is empty.

So make sure the directory is empty (check with ls -a), otherwise the command will fail.

Try:

$ rm YOUR_PROJECT_DIR/.metadata/.plugins/org.eclipse.core.resources/.snap

If it gives you permission denial while moving to /var/lib/mysql then use the following solution

$ cd /var/lib/
$ sudo -u mysql myisamchk -r -v -f mysql/<DB_NAME>/<TABLE_NAME>

In order to start an activity which should return result to the calling activity, you should do something like below. You should pass the requestcode as shown below in order to identify that you got the result from the activity you started.

startActivityForResult(new Intent(“YourFullyQualifiedClassName”),requestCode);

In the activity you can make use of setData() to return result.

Intent data = new Intent();
String text = "Result to be returned...."
//---set the data to pass back---
data.setData(Uri.parse(text));
setResult(RESULT_OK, data);
//---close the activity---
finish();

So then again in the first activity you write the below code in onActivityResult()

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String returnedResult = data.getData().toString();
            // OR
            // String returnedResult = data.getDataString();
        }
    }
}

EDIT based on your comment: If you want to return three strings, then follow this by making use of key/value pairs with intent instead of using Uri.

Intent data = new Intent();
data.putExtra("streetkey","streetname");
data.putExtra("citykey","cityname");
data.putExtra("homekey","homename");
setResult(RESULT_OK,data);
finish();

Get them in onActivityResult like below:

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == request_Code) {
        if (resultCode == RESULT_OK) {
            String street = data.getStringExtra("streetkey");
            String city = data.getStringExtra("citykey");
            String home = data.getStringExtra("homekey");
        }
    }
}

Because a null collection is not the same thing as an empty collection. An empty collection is a collection object with no elements; a null collection is a nonexistent object.

Here's something to try: Declare two collections of any sort. Initialize one normally so that it's empty, and assign the other the value null. Then try adding an object to both collections and see what happens.

As far as I know there is no native WPF function to get dimensions of the current monitor. Instead you could PInvoke native multiple display monitors functions, wrap them in managed class and expose all properties you need to consume them from XAML.

You can create files in browser using Blob and URL.createObjectURL. All recent browsers support this.

You can not directly save the file you create, since that would cause massive security problems, but you can provide it as a download link for the user. You can suggest a file name via the download attribute of the link, in browsers that support the download attribute. As with any other download, the user downloading the file will have the final say on the file name though.

var textFile = null,
  makeTextFile = function (text) {
    var data = new Blob([text], {type: 'text/plain'});

    // If we are replacing a previously generated file we need to
    // manually revoke the object URL to avoid memory leaks.
    if (textFile !== null) {
      window.URL.revokeObjectURL(textFile);
    }

    textFile = window.URL.createObjectURL(data);

    // returns a URL you can use as a href
    return textFile;
  };

Here's an example that uses this technique to save arbitrary text from a textarea.

If you want to immediately initiate the download instead of requiring the user to click on a link, you can use mouse events to simulate a mouse click on the link as Lifecube's answer did. I've created an updated example that uses this technique.

  var create = document.getElementById('create'),
    textbox = document.getElementById('textbox');

  create.addEventListener('click', function () {
    var link = document.createElement('a');
    link.setAttribute('download', 'info.txt');
    link.href = makeTextFile(textbox.value);
    document.body.appendChild(link);

    // wait for the link to be added to the document
    window.requestAnimationFrame(function () {
      var event = new MouseEvent('click');
      link.dispatchEvent(event);
      document.body.removeChild(link);
    });

  }, false);

Use ThisWorkbook which will refer to the original workbook which holds the code.

Alternatively at code start

Dim Wb As Workbook
Set Wb = ActiveWorkbook

sample code that activates all open books before returning to ThisWorkbook

Sub Test()
Dim Wb As Workbook
Dim Wb2 As Workbook
Set Wb = ThisWorkbook
For Each Wb2 In Application.Workbooks
    Wb2.Activate
Next
Wb.Activate
End Sub

Check file permissions of the /var/www/html and the ALLOW directive in your apache conf

Make sure all files are readable by the webserver and the allow directive is like

 <Directory "/var/www/html">
    Order allow,deny
    Allow from all
  </Directory>

if you can see files then consider sorting the directive to be more restrictive

It's really simple to fix the issue, however keep in mind that you should fork and commit your changes for each library you are using in their repositories to help others as well.

Let's say you have something like this in your code:

$str = "test";
echo($str{0});

since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:

$str = "test";
echo($str[0]);

Fixing the code in the question will look something like this:

public function getRecordID(string $zoneID, string $type = '', string $name = ''): string
{
    $records = $this->listRecords($zoneID, $type, $name);
    if (isset($records->result[0]->id)) {
        return $records->result[0]->id;
    }
    return false;
}

I'm going to have to say curl http://127.0.0.1:8000 -o outfile

There are also several jquery plugins that deal with this issue, but many do not handle multiple lines of text. Following works:

• http://pvdspek.github.com/jquery.autoellipsis/
• http://dotdotdot.frebsite.nl/
• http://keith-wood.name/more.html
• http://github.com/tbasse/jquery-truncate

There also some preformance tests.

Use next:

(1..10).each do |a|
  next if a.even?
  puts a
end

prints:

1
3   
5
7
9

For additional coolness check out also redo and retry.

Works also for friends like times, upto, downto, each_with_index, select, map and other iterators (and more generally blocks).

For more info see http://ruby-doc.org/docs/ProgrammingRuby/html/tut_expressions.html#UL.

You may find that you have to link with the math libraries on whatever system you're using, something like:

gcc -o myprog myprog.c -L/path/to/libs -lm
                                       ^^^ - this bit here.

Including headers lets a compiler know about function declarations but it does not necessarily automatically link to the code required to perform that function.

Failing that, you'll need to show us your code, your compile command and the platform you're running on (operating system, compiler, etc).

The following code compiles and links fine:

#include <math.h>
int main (void) {
    int max = sqrt (9);
    return 0;
}

Just be aware that some compilation systems depend on the order in which libraries are given on the command line. By that, I mean they may process the libraries in sequence and only use them to satisfy unresolved symbols at that point in the sequence.

So, for example, given the commands:

gcc -o plugh plugh.o -lxyzzy
gcc -o plugh -lxyzzy plugh.o

and plugh.o requires something from the xyzzy library, the second may not work as you expect. At the point where you list the library, there are no unresolved symbols to satisfy.

And when the unresolved symbols from plugh.o do appear, it's too late.

This error, as correctly identified above, is due to the compiler not using c++11 or above standard. This answer is for Windows 10.

For c++11 and above standard support in codeblocks version 17:

1. Click settings in the toolbar.

2. A drop-down menu appears. Select compiler option.

3. Choose Global Compiler Settings.

4. In the toolbar in this new window in second section, choose compiler settings.

5. Then choose compiler flags option in below toolbar.

6. Unfold general tab. Check the C++ standard that you want your compiler to follow.

7. Click OK.

For those who are trying to get C++11 support in Sublime text.

1. Download mingw compiler version 7 or above. In versions below this, the default c++ standard used is c++98 whereas in versions higher than 7, the default standard used is c++11.

2. Copy the folder in main C drive. It should not be inside any other folder in C drive.

3. Rename the folder as MinGW. This name is case insensitive, so it should any variation of mingw and must not include any other characters in the name.

4. Then go to environment variables and edit the path variable. Add this "C:\mingw\bin" and click OK.

5. You can check the version of g++ in cmd by typing g++ -v.

6. This should be sufficient to enable c++11 in sublime text.

If you want your requests to persists try this:

example: on your JSP or servlet page

request.getSession().setAttribute("SUBFAMILY", subFam);

and on any receiving page use the below lines to retrieve your session and data:

SubFamily subFam = (SubFamily)request.getSession().getAttribute("SUBFAMILY");

Following worked for me:

1. Uninstall the previously installed ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’.
2. Install 64-bit versions of ‘Microsoft Online Service Sign-in Assistant’ and ‘Windows Azure Active Directory Module for Windows PowerShell’. https://littletalk.wordpress.com/2013/09/23/install-and-configure-the-office-365-powershell-cmdlets/

If you get the following error In order to install Windows Azure Active Directory Module for Windows PowerShell, you must have Microsoft Online Services Sign-In Assistant version 7.0 or greater installed on this computer, then install the Microsoft Online Services Sign-In Assistant for IT Professionals BETA: http://www.microsoft.com/en-us/download/details.aspx?id=39267

3. Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

https://stackoverflow.com/a/16018733/5810078.

(But I have actually copied all the possible files from

C:\Windows\System32\WindowsPowerShell\v1.0\

to

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\

(For copying you need to alter the security permissions of that folder))

Since all the answers allow NaN to be included, I thought I'd add that if you want to quickly cast an array of mixed values to numbers you can do.

var a = "1,2,3,4,foo,bar";

var b = a.split(',');

var result = b.map(_=>_|0) // Floors the number (32-bit signed integer) so this wont work if you need all 64 bits.

// or b.map(_=>_||0) if you know your array is just numbers but may include NaN.

Chapter and verse

6.5.5 Multiplicative operators
...
6 When integers are divided, the result of the / operator is the algebraic quotient with any fractional part discarded.¹⁰⁵⁾ If the quotient a/b is representable, the expression (a/b)*b + a%b shall equal a; otherwise, the behavior of both a/b and a%b is unde?ned.

---

^{105) This is often called ‘‘truncation toward zero’’.}

Dividing an integer by an integer gives an integer result. 1/2 yields 0; assigning this result to a floating-point variable gives 0.0. To get a floating-point result, at least one of the operands must be a floating-point type. b = a / 350.0f; should give you the result you want.

Use id as primary key with auto increment

$stmt->execute();
$insertid = $conn->lastInsertId();

incremental id is always bigger than zero even on first record so that means it will always return a true value for id coz bigger than zero means true in PHP

if ($insertid)
   echo "record inserted successfully";
else
   echo "record insertion failed";

StartDate = moment(StartDate).format('MM-YYYY');

...and MySQL date format:

StartDate = moment(StartDate).format('YYYY-MM-DD');

Python 3.6

Just to make it clear, you can use f-string formatting. This has almost the same syntax as the format method, but make it a bit nicer.

Example:

print(f'{numvar:.9f}')

• Really good blog post - talks about performance too

Here is a diagram of the execution times of the various tested methods (from last link above):

for /f "delims=" %a in (downing.txt) do echo %a & pause>nul

Prints 1st line, then waits for user to press a key to print next line. After printing required lines, press Ctrl+C to stop.

@Ross Presser: This method prints lines only, not prepend line numbers.

if response.status_code == 429:
  time.sleep(int(response.headers["Retry-After"]))

Try this code:

$(document).ready(function(){
    $('#YourControlID').click(function(){
        if() { //your condition
            $.messager.show({  
                title:'My Title',  
                msg:'The message content',  
                showType:'fade',  
                style:{  
                    right:'',  
                    bottom:''  
                }  
            });  
        }
    });
});

What you should do is to serialize your form data and send it to the controller action. ASP.NET MVC will bind the form data to the EditPostViewModel object( your action method parameter), using MVC model binding feature.

You can validate your form at client side and if everything is fine, send the data to server. The valid() method will come in handy.

$(function () {

    $("#yourSubmitButtonID").click(function (e) {

        e.preventDefault();
        var _this = $(this);
        var _form = _this.closest("form");

        var isvalid = _form .valid();  // Tells whether the form is valid

        if (isvalid)
        {           
           $.post(_form.attr("action"), _form.serialize(), function (data) {
              //check the result and do whatever you want
           })
        }

    });

});

I started off using curl, but since have migrated to use kibana. Here is some more information on the ELK stack from elastic.co (E elastic search, K kibana): https://www.elastic.co/elk-stack

With kibana your POST requests are a bit more simple:

POST /<INDEX_NAME>/<TYPE_NAME>
{
    "field": "value",
    "id": 1,
    "account_id": 213,
    "name": "kimchy"
}

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

I had a similar case, what worked for me was:

name.firstChild.childNodes[0].data

XML is supposed to be simple and it really is and I don't know why python's minidom did it so complicated... but it's how it's made

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

Swift 3 & 4

Swift 3, and now Swift 4, have replaced many "stringly-typed" APIs with struct "wrapper types", as is the case with NotificationCenter. Notifications are now identified by a struct Notfication.Name rather than by String. For more details see the now legacy Migrating to Swift 3 guide

Swift 2.2 usage:

// Define identifier
let notificationIdentifier: String = "NotificationIdentifier"

// Register to receive notification
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification(_:)), name: notificationIdentifier, object: nil)

// Post a notification
NSNotificationCenter.defaultCenter().postNotificationName(notificationIdentifier, object: nil)

Swift 3 & 4 usage:

// Define identifier
let notificationName = Notification.Name("NotificationIdentifier")

// Register to receive notification
NotificationCenter.default.addObserver(self, selector: #selector(YourClassName.methodOfReceivedNotification), name: notificationName, object: nil)

// Post notification
NotificationCenter.default.post(name: notificationName, object: nil)

// Stop listening notification
NotificationCenter.default.removeObserver(self, name: notificationName, object: nil)

All of the system notification types are now defined as static constants on Notification.Name; i.e. .UIApplicationDidFinishLaunching, .UITextFieldTextDidChange, etc.

You can extend Notification.Name with your own custom notifications in order to stay consistent with the system notifications:

// Definition:
extension Notification.Name {
    static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: .yourCustomNotificationName, object: nil)

Swift 4.2 usage:

Same as Swift 4, except now system notifications names are part of UIApplication. So in order to stay consistent with the system notifications you can extend UIApplication with your own custom notifications instead of Notification.Name :

// Definition:
UIApplication {
    public static let yourCustomNotificationName = Notification.Name("yourCustomNotificationName")
}

// Usage:
NotificationCenter.default.post(name: UIApplication.yourCustomNotificationName, object: nil)

Here's some full and simple code to do this. This worked fine when I used it.

var processStartInfo = new ProcessStartInfo
{
    FileName = @"C:\SomeProgram",
    Arguments = "Arguments",
    RedirectStandardOutput = true,
    UseShellExecute = false
};
var process = Process.Start(processStartInfo);
var output = process.StandardOutput.ReadToEnd();
process.WaitForExit();

Note that this only captures standard output; it doesn't capture standard error. If you want both, use this technique for each stream.

Reinitialise the view controller

YourViewController *vc = [[YourViewController alloc] initWithNibName:@"YourViewControllerIpad" bundle:nil];
[self.navigationController vc animated:NO];

In my case I need frames at least every second. I used the 'seek to' approach above but wondered if I could parallelize the task. I used the N processes with FIFO approach here: https://unix.stackexchange.com/questions/103920/parallelize-a-bash-for-loop/216475#216475

open_sem(){
  mkfifo /tmp/pipe-$$
  exec 3<>/tmp/pipe-$$
  rm /tmp/pipe-$$
  local i=$1
  for((;i>0;i--)); do
    printf %s 000 >&3
  done
}
run_with_lock(){
    local x
    read -u 3 -n 3 x && ((0==x)) || exit $x
    (
    "$@" 
    printf '%.3d' $? >&3
    )&
}
N=16
open_sem $N
time for i in {0..39} ; do run_with_lock ffmpeg -ss `echo $i` -i /tmp/input/GOPR1456.MP4  -frames:v 1 /tmp/output/period_down_$i.jpg  & done

Essentially I forked the process with & but limited the number of concurrent threads to N.

This improved the 'seek to' approach from 26 seconds to 16 seconds in my case. The only problem is the main thread does not exit cleanly back to the terminal since stdout gets flooded.

Apache tomcat is just an only serverlet container it does not support for Enterprise Java application(JEE). JBoss and Glassfish are supporting for JEE application but Glassfish much heavy than JBOSS server : Reference Slide

If you don't want to block the current thread by waiting/checking for the other running thread completion, you can implement callback method like this.

Action onCompleted = () => 
{  
    //On complete action
};

var thread = new Thread(
  () =>
  {
    try
    {
      // Do your work
    }
    finally
    {
      onCompleted();
    }
  });
thread.Start();

If you are dealing with controls that doesn't support cross-thread operation, then you have to invoke the callback method

this.Invoke(onCompleted);

I would use a decimal with the proper precision for your data.

As an addition about the core of Mac OS X, Finder had not been written in Objective-C prior to Snow Leopard. In Snow Leopard it was written in Cocoa, Objective-C

It's a new feature called Modules or "semantic import". There's more info in the WWDC 2013 videos for Session 205 and 404. It's kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework executable and its headers and are touted as being safer and more efficient than #import.

One of the big advantages of using @import is that you don't need to add the framework in the project settings, it's done automatically. That means that you can skip the step where you click the plus button and search for the framework (golden toolbox), then move it to the "Frameworks" group. It will save many developers from the cryptic "Linker error" messages.

You don't actually need to use the @import keyword. If you opt-in to using modules, all #import and #include directives are mapped to use @import automatically. That means that you don't have to change your source code (or the source code of libraries that you download from elsewhere). Supposedly using modules improves the build performance too, especially if you haven't been using PCHs well or if your project has many small source files.

Modules are pre-built for most Apple frameworks (UIKit, MapKit, GameKit, etc). You can use them with frameworks you create yourself: they are created automatically if you create a Swift framework in Xcode, and you can manually create a ".modulemap" file yourself for any Apple or 3rd-party library.

You can use code-completion to see the list of available frameworks:

Modules are enabled by default in new projects in Xcode 5. To enable them in an older project, go into your project build settings, search for "Modules" and set "Enable Modules" to "YES". The "Link Frameworks" should be "YES" too:

You have to be using Xcode 5 and the iOS 7 or Mavericks SDK, but you can still release for older OSs (say iOS 4.3 or whatever). Modules don't change how your code is built or any of the source code.

From the WWDC slides:

• Imports complete semantic description of a framework
• Doesn't need to parse the headers
• Better way to import a framework’s interface
• Loads binary representation
• More flexible than precompiled headers
• Immune to effects of local macro definitions (e.g. #define readonly 0x01)
• Enabled for new projects by default

To explicitly use modules:

Replace #import <Cocoa/Cocoa.h> with @import Cocoa;

You can also import just one header with this notation:

@import iAd.ADBannerView;

The submodules autocomplete for you in Xcode.

Extend TextView and override onDraw with the code below. It will keep text aspect ratio but size it to fill the space. You could easily modify code to stretch if necessary.

  @Override
  protected void onDraw(@NonNull Canvas canvas) {
    TextPaint textPaint = getPaint();
    textPaint.setColor(getCurrentTextColor());
    textPaint.setTextAlign(Paint.Align.CENTER);
    textPaint.drawableState = getDrawableState();

    String text = getText().toString();
    float desiredWidth = getMeasuredWidth() - getPaddingLeft() - getPaddingRight() - 2;
    float desiredHeight = getMeasuredHeight() - getPaddingTop() - getPaddingBottom() - 2;
    float textSize = textPaint.getTextSize();

    for (int i = 0; i < 10; i++) {
      textPaint.getTextBounds(text, 0, text.length(), rect);
      float width = rect.width();
      float height = rect.height();

      float deltaWidth = width - desiredWidth;
      float deltaHeight = height - desiredHeight;

      boolean fitsWidth = deltaWidth <= 0;
      boolean fitsHeight = deltaHeight <= 0;

      if ((fitsWidth && Math.abs(deltaHeight) < 1.0)
          || (fitsHeight && Math.abs(deltaWidth) < 1.0)) {
        // close enough
        break;
      }

      float adjustX = desiredWidth / width;
      float adjustY = desiredHeight / height;

      textSize = textSize * (adjustY < adjustX ? adjustY : adjustX);

      // adjust text size
      textPaint.setTextSize(textSize);
    }
    float x = desiredWidth / 2f;
    float y = desiredHeight / 2f - rect.top - rect.height() / 2f;
    canvas.drawText(text, x, y, textPaint);
  }

The toPrecision(no_of_digits_required) function returns a string so don't forget to use the parseFloat() function to convert to decimal point of required precision.

You can overload the method with different parameters:

}

public int doSomething(

doSomething(0,0)
}

Word up, I as well got tired of writing out enumerations based on Id / Name db table columns, copying and pasting stuff from queries in SSMS.

Below is a super dirty stored procedure that takes as input a table name, the column name you want to use for the c# enumeration name, and the column name that you want to use for the c# enumeration value.

Most of theses table names I work with a) end with "s" b) have a [TABLENAME]Id column and c) have a [TABLENAME]Name column, so there are a couple if statements that will assume that structure, in which case, the column name parameters are not required.

A little context for these examples - "Stonk" here doesn't really mean "stock" but kinda, the way I'm using "stonk" it means "a thing that has some numbers associated to it for a time period" But that's not important, it's just an example of table with this Id / Name schema. It looks like this:

CREATE TABLE StonkTypes (
    StonkTypeId TINYINT IDENTITY(1,1) PRIMARY KEY NOT NULL,
    StonkTypeName VARCHAR(200) NOT NULL CONSTRAINT UQ_StonkTypes_StonkTypeName UNIQUE (StonkTypeName)
)

After I create the proc, this statement:

EXEC CreateCSharpEnum 'StonkTypes'

Selects this string:

public enum StonkTypes { Stonk = 1, Bond = 2, Index = 3, Fund = 4, Commodity = 5, 
PutCallRatio = 6, }

Which I can copy and paste into a C# file.

I have a Stonks table and it has StonkId and StonkName columns so this exec:

EXEC CreateCSharpEnum 'Stonks'

Spits out:

public enum Stonks { SP500 = 1, DowJonesIndustrialAverage = 2, ..... }

But for that enum I want to use the "Symbol" column for the enum name values so this:

EXEC CreateCSharpEnum 'Stonks', 'Symbol'

Does the trick and renders:

public enum Stonks { SPY = 1, DIA = 2, ..... }

Without further ado, here is this dirty piece of craziness. Yeah, very dirty, but I'm kind of pleased with myself - it's SQL code that constructs SQL code that constructs C# code. Couple layers involved.

CREATE OR ALTER PROCEDURE CreateCSharpEnum
@TableName VARCHAR(MAX),
@EnumNameColumnName VARCHAR(MAX) = NULL,

    SET @TableNameWithoutS = LEFT(@TableName, LEN(@TableName) - 1)

    END

DECLARE @csharpenum VARCHAR(MAX) = 'public enum ' + @TableName + ' { ' + @csharpenumbody + ' }'

PRINT @csharpenum

SELECT @csharpenum

DROP TABLE #EnumRowsTemp

Please, be critical. One funky thing I didn't understand, how come I have to create and drop this #EnumRowsTemp table and not just "SELECT INTO #EnumRowsTemp" to create the temp table on the fly? I don't know the answer, I tried that and it didn't work. That's probably the least of the problems of this code...

As dirty as it may be... I hope this saves some of you fellow dorks a little bit of time.

replace the values using the round function, and format the string representation of the percentage numbers:

df['var2'] = pd.Series([round(val, 2) for val in df['var2']], index = df.index)
df['var3'] = pd.Series(["{0:.2f}%".format(val * 100) for val in df['var3']], index = df.index)

The round function rounds a floating point number to the number of decimal places provided as second argument to the function.

String formatting allows you to represent the numbers as you wish. You can change the number of decimal places shown by changing the number before the f.

p.s. I was not sure if your 'percentage' numbers had already been multiplied by 100. If they have then clearly you will want to change the number of decimals displayed, and remove the hundred multiplication.

With absolute or relative positioning, you can do all sorts of overlapping. You've probably want the logo to be styled as such:

div#logo {
  position: absolute;
  left: 100px; // or whatever
}

Note: absolute position has its eccentricities. You'll probably have to experiment a little, but it shouldn't be too hard to do what you want.

No, you don't want a generic method. This is much easier:

MyEnum myEnum = (MyEnum)myInt;

MyEnum myEnum = (MyEnum)Enum.Parse(typeof(MyEnum), myString);

I think it will also be faster.

Add MultipleActiveResultSets=true to the provider part of your connection string. See the example below:

<add name="DbContext" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog=dbName;Persist Security Info=True;User ID=userName;Password=password;MultipleActiveResultSets=True" providerName="System.Data.SqlClient" />

Basically modulus Operator gives you remainder simple Example in maths what's left over/remainder of 11 divided by 3? answer is 2

for same thing C++ has modulus operator ('%')

Basic code for explanation

#include <iostream>
using namespace std;


int main()
{
    int num = 11;
    cout << "remainder is " << (num % 3) << endl;

    return 0;
}

Which will display

remainder is 2

Try the following expression

/^\d{0,2}(\.\d{1,2})?$/.test()

I agree with Greg that a two phase approach is a reasonable solution, however I would do it the other way around. I would do:

POST http://server/data/media
body:
{
    "Name": "Test",
    "Latitude": 12.59817,
    "Longitude": 52.12873
}

To create the metadata entry and return a response like:

201 Created
Location: http://server/data/media/21323
{
    "Name": "Test",
    "Latitude": 12.59817,
    "Longitude": 52.12873,
    "ContentUrl": "http://server/data/media/21323/content"
}

The client can then use this ContentUrl and do a PUT with the file data.

The nice thing about this approach is when your server starts get weighed down with immense volumes of data, the url that you return can just point to some other server with more space/capacity. Or you could implement some kind of round robin approach if bandwidth is an issue.

Another string approach. Short and sweet - for any integer n.

int length = ("" + n).length();

On macOS High Sierra, this solved my issue:

sudo gem update --system -n /usr/local/bin/gem

I have taken my example from a couple different websites on google. I have tested this on ff 5.0, IE 8.0, and Chrome 10. It works on all of them.

This can be a IPv6 problem (the host publishes an IPv6 AAAA-Address and the users host thinks it is configured for IPv6 but it is actually not correctly connected). This can also be a network MTU problem, a firewall block, or the target host might publish different IP addresses (randomly or based on originators country) which are not all reachable. Or similliar network problems.

You cant do much besides setting a timeout and adding good error messages (especially printing out the hosts' resolved address). If you want to make it more robust add retry, parallel trying of all addresses and also look into name resolution caching (positive and negative) on the Java platform.

See this answer https://stackoverflow.com/a/23010605/2760919

For your case, just change the type in snprintf from long ("%ld") to int ("%n").

An array is a fixed collection of same-type data that are stored contiguously and that are accessible by an index (zero based).

A string is a sequence of characters.

Hence a String[] is a collection of Strings.

For example:

String foo = "Foo";  // one instance of String
String[] foos = new String[] { "Foo1", "Foo2", "Foo3" };
String firstFoo = foos[0];  // "Foo1"

Arrays (C# Programming Guide)

Edit: So obviously there's no direct way to convert a single String to an String[] or vice-versa. Though you can use String.Split to get a String[] from a String by using a separator(for example comma).

To "convert" a String[] to a String(the opposite) you can use String.Join. You need to specify how you want to join those strings(f.e. with comma).

Here's an example:

var foos = "Foo1,Foo2,Foo3";
var fooArray = foos.Split(',');  // now you have an array of 3 strings
foos = String.Join(",", fooArray); // now you have the same as in the first line

The reliable solution is catching the ObjectDisposedException.

The solution to write your overridden implementation of the Dispose method doesn't work, since there is a race condition between the thread calling Dispose method and the one accessing to the object: after having checked the hypothetic IsDisposed property , the object could be really disposed, throwing the exception all the same.

Another approach could be exposing a hypothetic event Disposed (like this), which is used to notify about the disposing object to every object interested, but this could be difficoult to plan depending on the software design.

Based on Ramon's answer I run into an error. The problem where spaces in the JSON I tried to write I got it fixed by changing the task in the playbook to look like:

- copy:
    content: "{{ your_json_feed }}"
    dest: "/path/to/destination/file"

As of now I am not sure why this was needed. My best guess is that it had something to do with how variables are replaced in Ansible and the resulting file is parsed.

class B is only declared but not defined at the beginning, which is what the compiler complains about. The root cause is that in class A's Call Function, you are referencing instance b of type B, which is incomplete and undefined. You can modify source like this without introducing new file(just for sake of simplicity, not recommended in practice):

using namespace std;

class A 
{
public:

    void CallFunction ();
};

class B: public A
{
public:
    virtual void bFunction()
    {
        //stuff done here
    }
};


 // postpone definition of CallFunction here

 void A::CallFunction ()
 {
     B b;
     b.bFunction();
 }

In CMD, type:

pip freeze

They way I handle this problem is recursively. For example when reading data from the console:

Java.util.Scanner keyboard = new Java.util.Scanner(System.in);

public int GetMyInt(){
    int ret;
    System.out.print("Give me an Int: ");
    try{
        ret = Integer.parseInt(keyboard.NextLine());

    }
    catch(Exception e){
        System.out.println("\nThere was an error try again.\n");
        ret = GetMyInt();
    }
    return ret;
}

This was my error message:

Error: Error Parsing C:\Android\sdk\system-images\android-22\android-wear\armeabi-v7a\devices.xml Invalid content was found starting with element 'd:Skin'. No child element is expected at this point.

There´s a kind of problem with android Wear packages for API 22, so my solution was deleting this two packages from the API 22

You could use the string.join method in this case.

Split over a few of lines for clarity - here's an interactive session

>>> a = ['a','b','c']
>>> first = '", "'.join(a)
>>> second = '"%s"' % first
>>> print second
"a", "b", "c"

Or as a single line

>>> print ('"%s"') % '", "'.join(a)
"a", "b", "c"

However, you may have a problem is your strings have got embedded quotes. If this is the case you'll need to decide how to escape them.

The CSV module can take care of all of this for you, allowing you to choose between various quoting options (all fields, only fields with quotes and seperators, only non numeric fields, etc) and how to esacpe control charecters (double quotes, or escaped strings). If your values are simple, string.join will probably be OK but if you're having to manage lots of edge cases, use the module available.

The way via unlist and matrix seems a bit convoluted, and requires you to hard-code the number of elements (this is actually a pretty big no-go. Of course you could circumvent hard-coding that number and determine it at run-time)

I would go a different route, and construct a data frame directly from the list that strsplit returns. For me, this is conceptually simpler. There are essentially two ways of doing this:

1. as.data.frame – but since the list is exactly the wrong way round (we have a list of rows rather than a list of columns) we have to transpose the result. We also clear the rownames since they are ugly by default (but that’s strictly unnecessary!):

   `rownames<-`(t(as.data.frame(strsplit(text, '\\.'))), NULL)
   

2. Alternatively, use rbind to construct a data frame from the list of rows. We use do.call to call rbind with all the rows as separate arguments:

   do.call(rbind, strsplit(text, '\\.'))
   

Both ways yield the same result:

     [,1] [,2] [,3]  [,4]
[1,] "F"  "US" "CLE" "V13"
[2,] "F"  "US" "CA6" "U13"
[3,] "F"  "US" "CA6" "U13"
[4,] "F"  "US" "CA6" "U13"
[5,] "F"  "US" "CA6" "U13"
[6,] "F"  "US" "CA6" "U13"
…

Clearly, the second way is much simpler than the first.

Not direct answer to your question, but I've been quite frustrated myself trying find and update all of the tnsnames files, as I had several oracle installs: Client, BI tools, OWB, etc, each of which had its own oracle home. I ended up creating a utility called TNSNamesSync that will update all of the tnsnames in all of the oracle homes. It's under the MIT license, free to use here https://github.com/artybug/TNSNamesSync/releases

The docs are here: https://github.com/artchik/TNSNamesSync/blob/master/README.md

This is for Windows only, though.

I'm running Chrome version 60 and none of the previous CSS answers worked.

I found that Chrome was adding the blue highlight via the outline style. Adding the following CSS fixed it for me:

:focus {
    outline: none !important;
}

This answer focusses more on the sidenote "i.e. has at least one alphanumeric character". Besides that, it doesn't add too much to the other (earlier) solution, except that it doesn't hurt you with NPE in case the String is null.

We want false if (1) s is null or (2) s is empty or (3) s only contains whitechars.

public static boolean containsNonWhitespaceChar(String s) {
  return !((s == null) || "".equals(s.trim()));
}

The other solutions here don't actually work for divs with lots of content -- it "maxes out" scrolling down to the height of the div (instead of the height of the content of the div). So they'll work, unless you have more than double the div's height in content inside of it.

Here is the correct version:

$('#div1').scrollTop($('#div1')[0].scrollHeight);

or jQuery 1.6+ version:

var d = $('#div1');
d.scrollTop(d.prop("scrollHeight"));

Or animated:

$("#div1").animate({ scrollTop: $('#div1').prop("scrollHeight")}, 1000);

One area where I found mmap() to not be an advantage was when reading small files (under 16K). The overhead of page faulting to read the whole file was very high compared with just doing a single read() system call. This is because the kernel can sometimes satisify a read entirely in your time slice, meaning your code doesn't switch away. With a page fault, it seemed more likely that another program would be scheduled, making the file operation have a higher latency.

Until 24 hrs. As Duration.format is deprecated, with [email protected]

const seconds = 123;
moment.utc(moment.duration(seconds,'seconds').as('milliseconds')).format('HH:mm:ss');

if you have a subfolder, which was cloned from other git-Repository, first you have to remove the $.git$ file from the child-Repository: rm -rf .git after that you can change to parent folder and use git add -A.

The new line character is \n, like so:

echo __("Thanks for your email.\n<br />\n<br />Your order's details are below:", 'jigoshop');

If you want to add a default value for the already created column, this works for me:

ALTER TABLE Persons
ALTER credit SET DEFAULT 0.0;

It is as simple as this:

var sel = document.getElementById('sel');
var button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;
    sel.onchange();
});

But this way has a problem. You can't call events just like you would, with normal functions, because there may be more than one function listening for an event, and they can get set in several different ways.

Unfortunately, the 'right way' to fire an event is not so easy because you have to do it differently in Internet Explorer (using document.createEventObject) and Firefox (using document.createEvent("HTMLEvents"))

var sel = document.getElementById('sel');
var button = document.getElementById('button');

button.addEventListener('click', function (e) {
    sel.options[1].selected = true;
    fireEvent(sel,'change');

});


function fireEvent(element,event){
    if (document.createEventObject){
    // dispatch for IE
    var evt = document.createEventObject();
    return element.fireEvent('on'+event,evt)
    }
    else{
    // dispatch for firefox + others
    var evt = document.createEvent("HTMLEvents");
    evt.initEvent(event, true, true ); // event type,bubbling,cancelable
    return !element.dispatchEvent(evt);
    }
}

First, add a pom.xml and make it a maven project and then build it. It will create a War file for you in the target folder after that you can deploy it wherever you want.

df.resample("1d").sum().fillna(0).rolling(window=3, min_periods=1).mean()

If child class has more members, than parent, it could be done not very clean, but short way:

@Data
@RequiredArgsConstructor
@EqualsAndHashCode(callSuper = true)
@ToString(callSuper = true)
public class User extends BaseEntity {
    private @NonNull String fullName;
    private @NonNull String email;
    ... 

    public User(Integer id, String fullName, String email, ....) {
        this(fullName, email, ....);
        this.id = id;
    }
}

@Data
@AllArgsConstructor
abstract public class BaseEntity {
   protected Integer id;

   public boolean isNew() {
      return id == null;
   }
}

Following the advice from NibblyPig and zendar, I came up with the code below, which works on every test I made. I ended up needing both the ping, and the poll. The ping will let me know if the cable has been disconnected, or the physical layer otherwise disrupted (router powered off, etc). But sometimes after reconnect I get a RST, the ping is ok, but the tcp state is not.

#region CHECKS THE SOCKET'S HEALTH
    if (_tcpClient.Client.Connected)
    {
            //Do a ping test to see if the server is reachable
            try
            {
                Ping pingTest = new Ping()
                PingReply reply = pingTest.Send(ServeripAddress);
                if (reply.Status != IPStatus.Success) ConnectionState = false;
            } catch (PingException) { ConnectionState = false; }

            //See if the tcp state is ok
            if (_tcpClient.Client.Poll(5000, SelectMode.SelectRead) && (_tcpClient.Client.Available == 0))
            {
                ConnectionState = false;
            }
        }
    }
    else { ConnectionState = false; }

Here's my pure pathlib recursive directory unlinker:

from pathlib import Path

def rmdir(directory):
    directory = Path(directory)
    for item in directory.iterdir():
        if item.is_dir():
            rmdir(item)
        else:

rmdir(Path("dir/"))

double d = 2.22977777;
d = ( (double) ( (int) (d * 1000.0) ) ) / 1000.0 ;

Of course, this won't work if you're trying to truncate rounding error, but it should work fine with the values you give in your examples. See the first two answers to this question for details on why it won't work sometimes.

As the recent developed Web Applications are using JavaScript, jQuery, AngularJS, ReactJS etc there is a possibility that to retrieve an attribute of an element through Selenium you have to induce WebDriverWait to synchronize the WebDriver instance with the lagging Web Client i.e. the Web Browser before trying to retrieve any of the attributes.

Some examples:

• Python:

  • To retrieve any attribute form a visible element (e.g. <h1> tag) you need to use the expected_conditions as visibility_of_element_located(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.visibility_of_element_located((By.ID, "org"))).get_attribute("attribute_name")
    

  • To retrieve any attribute form an interactive element (e.g. <input> tag) you need to use the expected_conditions as element_to_be_clickable(locator) as follows:

    attribute_value = WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID, "org"))).get_attribute("attribute_name")
    

HTML Attributes

Below is a list of some attributes often used in HTML

Note: A complete list of all attributes for each HTML element, is listed in: HTML Attribute Reference

Public Sub PDFTxtToPdf(ByVal sTxtfile As String, ByVal sPDFSourcefile As String)
        Dim sr As StreamReader = New StreamReader(sTxtfile)
    Dim doc As New Document()
    PdfWriter.GetInstance(doc, New FileStream(sPDFSourcefile, FileMode.Create))
    doc.Open()
    doc.Add(New Paragraph(sr.ReadToEnd()))
    doc.Close()
End Sub

JPanel jPanel = new JPanel();

jPanel.setBorder(BorderFactory.createLineBorder(Color.black));

Here not only jPanel, you can add border to any Jcomponent

You also can use ng-attr-src="{{variable}}" instead of src="{{variable}}" and the attribute will only be generated once the compiler compiled the templates. This is mentioned here in the documentation: https://docs.angularjs.org/guide/directive#-ngattr-attribute-bindings

None of these solutions worked for me. I needed to know the server port while constructing a Swagger configuration bean. Using ServerProperties worked for me:

import javax.annotation.PostConstruct;
import javax.inject.Inject;
import javax.ws.rs.ApplicationPath;

import io.swagger.jaxrs.config.BeanConfig;
import io.swagger.jaxrs.listing.ApiListingResource;
import io.swagger.jaxrs.listing.SwaggerSerializers;

import org.glassfish.jersey.server.ResourceConfig;
import org.springframework.stereotype.Component;

@Component
@ApplicationPath("api")
public class JerseyConfig extends ResourceConfig 
{
    @Inject
    private org.springframework.boot.autoconfigure.web.ServerProperties serverProperties;

    public JerseyConfig() 
    {
        property(org.glassfish.jersey.server.ServerProperties.BV_SEND_ERROR_IN_RESPONSE, true);
    }

    @PostConstruct
    protected void postConstruct()
    {
        // register application endpoints
        registerAndConfigureSwaggerUi();
    }

    private void registerAndConfigureSwaggerUi()
    {
        register(ApiListingResource.class);
        register(SwaggerSerializers.class);

        final BeanConfig config = new BeanConfig();
        // set other properties
        config.setHost("localhost:" + serverProperties.getPort()); // gets server.port from application.properties file         
    }
}

This example uses Spring Boot auto configuration and JAX-RS (not Spring MVC).

<div></div>

div {
  display: table;
  margin-right: auto;
  margin-left: auto;
}

>>> response='bababa'
...  if "K" in response.text:
...     raise ValueError("Not found")

Use this code:

driver.manage().window().maximize() 

works well,

Please make sure that you give enough time for the window to load before you declare this statement.

If you are finding any element to input some data then provide reasonable delay between this and the input statement.

just updated the springboot version to 2.1.3 and it worked of me

GCC 4.9 introduces a newer C++ ABI version than your system libstdc++ has, so you need to tell the loader to use this newer version of the library by adding that path to LD_LIBRARY_PATH. Unfortunately, I cannot tell you straight off where the libstdc++ so for your GCC 4.9 installation is located, as this depends on how you configured GCC. So you need something in the style of:

export LD_LIBRARY_PATH=/home/user/lib/gcc-4.9.0/lib:/home/user/lib/boost_1_55_0/stage/lib:$LD_LIBRARY_PATH

Note the actual path may be different (there might be some subdirectory hidden under there, like `x86_64-unknown-linux-gnu/4.9.0´ or similar).

Here are the basic instructions:-

1. Locate the "server.xml" file in the "conf" folder beneath Tomcat's base directory (i.e. %CATALINA_HOME%/conf/server.xml).
2. Open the file in an editor and search for <Connector.
3. Locate the relevant connector that is timing out - this will typically be the HTTP connector, i.e. the one with protocol="HTTP/1.1".
4. If a connectionTimeout value is set on the connector, it may need to be increased - e.g. from 20000 milliseconds (= 20 seconds) to 120000 milliseconds (= 2 minutes). If no connectionTimeout property value is set on the connector, the default is 60 seconds - if this is insufficient, the property may need to be added.
5. Restart Tomcat

This can also happen if data model is out of date.

Hopefully this will save someone else frustration :)

In [34]: a=np.arange(-10,10)

In [35]: a
Out[35]:

Out[36]: (array([16, 17, 18, 19]),)

In [37]: np.where(a>5)[0][0]

You are looking to see if a single value is in an array. Use in_array.

However note that case is important, as are any leading or trailing spaces. Use var_dump to find out the length of the strings too, and see if they fit.

Instead you should use $transitions http://angular-ui.github.io/ui-router/1.0.0-alpha.1/interfaces/transition.ihookregistry.html

This is how I achieved it:

First I have and AuthService with some useful functions

angular.module('myApp')

        .factory('AuthService',
                ['$http', '$cookies', '$rootScope',
                    function ($http, $cookies, $rootScope) {
                        var service = {};

                        // Authenticates throug a rest service
                        service.authenticate = function (username, password, callback) {

                            $http.post('api/login', {username: username, password: password})
                                    .success(function (response) {
                                        callback(response);
                                    });
                        };

                        // Creates a cookie and set the Authorization header
                        service.setCredentials = function (response) {
                            $rootScope.globals = response.token;

                            $http.defaults.headers.common['Authorization'] = 'Bearer ' + response.token;
                            $cookies.put('globals', $rootScope.globals);
                        };

                        // Checks if it's authenticated
                        service.isAuthenticated = function() {
                            return !($cookies.get('globals') === undefined);
                        };

                        // Clear credentials when logout
                        service.clearCredentials = function () {
                            $rootScope.globals = undefined;
                            $cookies.remove('globals');
                            $http.defaults.headers.common.Authorization = 'Bearer ';
                        };

                        return service;
                    }]);

Then I have this configuration:

angular.module('myApp', [
    'ui.router',
    'ngCookies'
])
        .config(['$stateProvider', '$urlRouterProvider',
            function ($stateProvider, $urlRouterProvider) {
                $urlRouterProvider.otherwise('/resumen');
                $stateProvider
                        .state("dashboard", {
                            url: "/dashboard",
                            templateUrl: "partials/dashboard.html",
                            controller: "dashCtrl",
                            data: {
                                authRequired: true
                            }
                        })
                        .state("login", {
                            url: "/login",
                            templateUrl: "partials/login.html",
                            controller: "loginController"
                        })
            }])

        .run(['$rootScope', '$transitions', '$state', '$cookies', '$http', 'AuthService',
            function ($rootScope, $transitions, $state, $cookies, $http, AuthService) {

                // keep user logged in after page refresh
                $rootScope.globals = $cookies.get('globals') || {};
                $http.defaults.headers.common['Authorization'] = 'Bearer ' + $rootScope.globals;

                $transitions.onStart({
                    to: function (state) {
                        return state.data != null && state.data.authRequired === true;
                    }
                }, function () {
                    if (!AuthService.isAuthenticated()) {
                        return $state.target("login");
                    }
                });
            }]);

You can see that I use

data: {
   authRequired: true
}

to mark the state only accessible if is authenticated.

then, on the .run I use the transitions to check the autheticated state

$transitions.onStart({
    to: function (state) {
        return state.data != null && state.data.authRequired === true;
    }
}, function () {
    if (!AuthService.isAuthenticated()) {
        return $state.target("login");
    }
});

I build this example using some code found on the $transitions documentation. I'm pretty new with the ui router but it works.

Hope it can helps anyone.

std::string var = "sometext" + somevar + "sometext" + somevar;

This doesn't work because the additions are performed left-to-right and "sometext" (the first one) is just a const char *. It has no operator+ to call. The simplest fix is this:

std::string var = std::string("sometext") + somevar + "sometext" + somevar;

Now, the first parameter in the left-to-right list of + operations is a std::string, which has an operator+(const char *). That operator produces a string, which makes the rest of the chain work.

You can also make all the operations be on var, which is a std::string and so has all the necessary operators:

var = "sometext";
var += somevar;
var += "sometext";
var += somevar;

Keyword float:

<h1 style="text-align:left;float:left;">Title</h1> 
<h2 style="text-align:right;float:right;">Context</h2> 
<hr style="clear:both;"/>

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

I Think that the problem is about encoding. That's why removing first line(with encoding byte) might solve the problem.

My solution for Data at the root level is invalid. Line 1, position 1. in XDocument.Parse(xmlString) was replacing it with XDocument.Load( new MemoryStream( xmlContentInBytes ) );

I've noticed that my xml string looked ok:

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

but in different text editor encoding it looked like this:

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

At the end i did not need the xml string but xml byte[]. If you need to use the string you should look for "invisible" bytes in your string and play with encodings to adjust the xml content for parsing or loading.

Hope it will help

Set on nav

style="position:fixed; width:100%;"

You could do that like this:

<script type="text/javascript">
     function product(a,b)
     {
     return a*b;
     }
    document.getElementById('myvalue').value = product(a,b);
 </script>

 <input type="hidden" value="THE OUTPUT OF PRODUCT FUNCTION" id="myvalue">

Replace following

curl_setopt ($setuploginurl, CURLOPT_SSLVERSION, 'CURL_SSLVERSION_TLSv1_2');

With

curl_setopt ($ch, CURLOPT_SSLVERSION, 6);

Should work flawlessly.

I meet same problem and solved it by:

• Closing all IDEA windows
• Delete C:/Userz/xx/.IdeaIC2019.3 folder
• Reopen IDEA

if you run something like this in a thread and save the ffmpeg_time property in a property of a method so you can access it, it would work very nice I get outputs like this: output be like if you use threading in tkinter

input = 'path/input_file.mp4'
output = 'path/input_file.mp4'
command = "ffmpeg -y -v quiet -stats -i \"" + str(input) + "\" -metadata title=\"@alaa_sanatisharif\" -preset ultrafast -vcodec copy -r 50 -vsync 1 -async 1 \"" + output + "\""
process = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.STDOUT, universal_newlines=True, shell=True)
for line in self.process.stdout:
    reg = re.search('\d\d:\d\d:\d\d', line)
    ffmpeg_time = reg.group(0) if reg else ''
    print(ffmpeg_time)

I found the InvokeRequired not reliable, so I simply use

if (!this.IsHandleCreated)
{
    this.CreateHandle();
}

2017 update

$lookup can now directly use an array as the local field. $unwind is no longer needed.

Old answer

The $lookup aggregation pipeline stage will not work directly with an array. The main intent of the design is for a "left join" as a "one to many" type of join ( or really a "lookup" ) on the possible related data. But the value is intended to be singular and not an array.

Therefore you must "de-normalise" the content first prior to performing the $lookup operation in order for this to work. And that means using $unwind:

db.orders.aggregate([
    // Unwind the source
    { "$unwind": "$products" },
    // Do the lookup matching
    { "$lookup": {
       "from": "products",
       "localField": "products",
       "foreignField": "_id",
       "as": "productObjects"
    }},
    // Unwind the result arrays ( likely one or none )
    { "$unwind": "$productObjects" },
    // Group back to arrays
    { "$group": {
        "_id": "$_id",
        "products": { "$push": "$products" },
        "productObjects": { "$push": "$productObjects" }
    }}
])

After $lookup matches each array member the result is an array itself, so you $unwind again and $group to $push new arrays for the final result.

Note that any "left join" matches that are not found will create an empty array for the "productObjects" on the given product and thus negate the document for the "product" element when the second $unwind is called.

Though a direct application to an array would be nice, it's just how this currently works by matching a singular value to a possible many.

As $lookup is basically very new, it currently works as would be familiar to those who are familiar with mongoose as a "poor mans version" of the .populate() method offered there. The difference being that $lookup offers "server side" processing of the "join" as opposed to on the client and that some of the "maturity" in $lookup is currently lacking from what .populate() offers ( such as interpolating the lookup directly on an array ).

This is actually an assigned issue for improvement SERVER-22881, so with some luck this would hit the next release or one soon after.

As a design principle, your current structure is neither good or bad, but just subject to overheads when creating any "join". As such, the basic standing principle of MongoDB in inception applies, where if you "can" live with the data "pre-joined" in the one collection, then it is best to do so.

The one other thing that can be said of $lookup as a general principle, is that the intent of the "join" here is to work the other way around than shown here. So rather than keeping the "related ids" of the other documents within the "parent" document, the general principle that works best is where the "related documents" contain a reference to the "parent".

So $lookup can be said to "work best" with a "relation design" that is the reverse of how something like mongoose .populate() performs it's client side joins. By idendifying the "one" within each "many" instead, then you just pull in the related items without needing to $unwind the array first.

If you're not interested in the details that git diff outputs you can just run git cherry which will output a list of commits your remote tracking branch has ahead of your local branch.

For example:

git fetch origin
git cherry master origin/master

Will output something like :

+ 2642039b1a4c4d4345a0d02f79ccc3690e19d9b1
+ a4870f9fbde61d2d657e97b72b61f46d1fd265a9

Indicates that there are two commits in my remote tracking branch that haven't been merged into my local branch.

This also works the other way :

    git cherry origin/master master

Will show you a list of local commits that you haven't pushed to your remote repository yet.

I also faced the same issue, when I was developing a application which exports project contents into excel file.

I could not found the resolution in forums for my problem, then I check the maximum capacity of excel and found below link which says

"Worksheet size 1,048,576 rows by 16,384 columns" and this was the issue in my case, I was exporting more than that rows. Refer below link for details

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

What about this shorter, more transparent, yet more intuitive with array_walk

$attributes = array(
  'data-href'   => 'http://example.com',
  'data-width'  => '300',
  'data-height' => '250',
  'data-type'   => 'cover',
);

$args = "";
array_walk(
    $attributes, 
    function ($item, $key) use (&$args) {
        $args .= $key ." = '" . $item . "' ";  
    }
);
// output: 'data-href="http://example.com" data-width="300" data-height="250" data-type="cover"

Change HeightConstraint and WidthConstraint Without creating IBOutlet.

Note: Assign height or width constraint in Storyboard or XIB file. after fetching this Constraint using this extension.

You can use this extension to fetch a height and width Constraint:

extension UIView {

var heightConstraint: NSLayoutConstraint? {
    get {
        return constraints.first(where: {
            $0.firstAttribute == .height && $0.relation == .equal
        })
    }
    set { setNeedsLayout() }
}

var widthConstraint: NSLayoutConstraint? {
    get {
        return constraints.first(where: {
            $0.firstAttribute == .width && $0.relation == .equal
        })
    }
    set { setNeedsLayout() }
}

}

You can use:

yourView.heightConstraint?.constant = newValue 

It's the Adjacent sibling selector.

From Splash of Style blog.

To define a CSS adjacent selector, the plus sign is used.

h1+p {color:blue;}

The above CSS code will format the first paragraph after (not inside) any h1 headings as blue.

h1>p selects any p element that is a direct (first generation) child (inside) of an h1 element.

• h1>p matches <h1> <p></p> </h1> (<p> inside <h1>)

h1+p will select the first p element that is a sibling (at the same level of the dom) as an h1 element.

• h1+p matches <h1></h1> <p><p/> (<p> next to/after <h1>)

function myFunction() {
  var sheetname = "DateEntry";//Sheet where you want to put the date
  var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName(sheetname);
    // You could use now Date(); on its own but it will not look nice.
  var date = Utilities.formatDate(new Date(), "GMT+5:30", "yyyy-MM-dd");
    //var endDate = date;
    sheet.getRange(sheet.getLastRow() + 1,1).setValue(date); //Gets the last row which had value, and goes to the next empty row to put new values.
}

If you prefer to see the size of all deleted file

as well as the associated SHA

git log --all --stat --diff-filter=D --oneline

add a -p to see the contents too

git log --all --stat --diff-filter=D -p

To narrow down to any file simply pipe to grep and search for file name

git log --all --stat --diff-filter=D --oneline | grep someFileName

You might also like this one if you know where the file is

git log --all --full-history -- someFileName

To dump a database into an SQL file use the following command.

mysqldump -u username -p database_name > database_name.sql

To import an SQL file into a database (make sure you are in the same directory as the SQL file or supply the full path to the file), do:

mysql -u username -p database_name < database_name.sql

Solution described here helped me (webarchive link).

First of all, you can add border to all elements to see what causes a new page to be appended (maybe some margins, paddings, etc).

div { border: 1px solid black;}

And the solution itself was to add the following styles:

html, body { height: auto; }

Here's how to do it with the basic file operations in Python. This opens one file, reads the data into memory, then opens the second file and writes it out.

in_file = open("in-file", "rb") # opening for [r]eading as [b]inary
data = in_file.read() # if you only wanted to read 512 bytes, do .read(512)
in_file.close()

out_file = open("out-file", "wb") # open for [w]riting as [b]inary
out_file.write(data)
out_file.close()

We can do this more succinctly by using the with keyboard to handle closing the file.

with open("in-file", "rb") as in_file, open("out-file", "wb") as out_file:
    out_file.write(in_file.read())

If you don't want to store the entire file in memory, you can transfer it in pieces.

piece_size = 4096 # 4 KiB

with open("in-file", "rb") as in_file, open("out-file", "wb") as out_file:
    while True:
        piece = in_file.read(piece_size)

        if piece == "":
            break # end of file

        out_file.write(piece)

Wrap your image with a span element with a black background.

.img-wrapper {
  display: inline-block;
  background: #000;
}

.item-fade {
  vertical-align: top;
  transition: opacity 0.3s;
  -webkit-transition: opacity 0.3s;
  opacity: 1;
}

.item-fade:hover {
  opacity: 0.2;
}

<span class="img-wrapper">
   <img class="item-fade" src="http://placehold.it/100x100/cf5" />
</span>

Sorry old post I know but I had the same issue, couldn't get any of the above to work for me, however I figured it out.

This worked for me:

SELECT DISTINCT [column]As UniqueValues FROM [db].[dbo].[table]

You can start reading from here jQuery.ajax()

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

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

More examples can be found in here

if array is look like this [null] or [null, null] or [null, null, null, ...]

you can use implode:

implode is use for convert array to string.

if(implode(null,$arr)==null){
     //$arr is empty
}else{
     //$arr has some value rather than null
}

It could also be because you're trying to put in a null value back into the database. So one of your transactions could have nulls in them.

Personally I'm doing this using ngx-material-file-input for the front-end, and Firebase for the back-end. More precisely Cloud Storage for Firebase for the back-end combined with Cloud Firestore. Below an example, which limits file to be not larger than 20 MB, and accepts only certain file extensions. I'm also using Cloud Firestore for storing links to the uploaded files, but you can skip this.

Not sure why you are not wrapping financial transactions in database transactions (as when you transfer funds from one account to another - you don't commit one side of the transaction at-a-time - this is why explicit transactions exist). Even if your code is braindead to business transactions as it sounds like it is, all transactional databases have the potential to do implicit rollbacks in the event of errors or failure. I think this discussion is way over your head.

If you are having locking problems, implement versioning and clean up your code.

No lock not only returns wrong values it returns phantom records and duplicates.

It is a common misconception that it always makes queries run faster. If there are no write locks on a table, it does not make any difference. If there are locks on the table, it may make the query faster, but there is a reason locks were invented in the first place.

In fairness, here are two special scenarios where a nolock hint may provide utility

1) Pre-2005 sql server database that needs to run long query against live OLTP database this may be the only way

2) Poorly written application that locks records and returns control to the UI and readers are indefinitely blocked. Nolock can be helpful here if application cannot be fixed (third party etc) and database is either pre-2005 or versioning cannot be turned on.

Because the original question was never answered, and I had to run into this same problem, the solution for the MD5 problem is that S3 doesn't want the Hex encoded MD5 string we normally think about.

Instead, I had to do this.

// content is a passed in InputStream
byte[] resultByte = DigestUtils.md5(content);
String streamMD5 = new String(Base64.encodeBase64(resultByte));
metaData.setContentMD5(streamMD5);

Essentially what they want for the MD5 value is the Base64 encoded raw MD5 byte-array, not the Hex string. When I switched to this it started working great for me.

For Mac OS X:

export ANDROID_HOME=/<installation location>/android-sdk-macosx
export PATH=${PATH}:$ANDROID_HOME/tools:$ANDROID_HOME/platform-tools

This can be done using ServerSocket, same as on JavaSE. This class is available on Android. android.permission.INTERNET is required.

The only more tricky part, you need a separate thread wait on the ServerSocket, servicing sub-sockets that come from its accept method. You also need to stop and resume this thread as needed. The simplest approach seems to kill the waiting thread by closing the ServerSocket. If you only need a server while your activity is on the top, starting and stopping ServerSocket thread can be rather elegantly tied to the activity life cycle methods. Also, if the server has multiple users, it may be good to service requests in the forked threads. If there is only one user, this may not be necessary.

If you need to tell the user on which IP is the server listening,use NetworkInterface.getNetworkInterfaces(), this question may tell extra tricks.

Finally, here there is possibly the complete minimal Android server that is very short, simple and may be easier to understand than finished end user applications, recommended in other answers.

This method works well for me. I use ISNULL() for the primary key field, and COALESCE() if the field should not be the primary key, but should also have a non-nullable value. This example yields ID field with a non-nullable primary key. The other fields are not keys, and have (None) as their Nullable attribute.

SELECT      
ISNULL(P.ID, - 1) AS ID,  
COALESCE (P.PurchaseAgent, U.[User Nickname]) AS PurchaseAgent,  
COALESCE (P.PurchaseAuthority, 0) AS PurchaseAuthority,  
COALESCE (P.AgencyCode, '') AS AgencyCode,  
COALESCE (P.UserID, U.ID) AS UserID,  
COALESCE (P.AssignPOs, 'false') AS AssignPOs,  
COALESCE (P.AuthString, '') AS AuthString,  
COALESCE (P.AssignVendors, 'false') AS AssignVendors 
FROM Users AS U  
INNER JOIN Users AS AU ON U.Login = AU.UserName  
LEFT OUTER JOIN PurchaseAgents AS P ON U.ID = P.UserID

if you really don't have a primary key, you can spoof one by using ROW_NUMBER to generate a pseudo-key that is ignored by your code. For example:

SELECT
ROW_NUMBER() OVER(ORDER BY A,B) AS Id,
A, B
FROM SOMETABLE

This is the most simple solution for me:

just the current date

$tStamp = Get-Date -format yyyy_MM_dd_HHmmss

current date with some months added

$tStamp = Get-Date (get-date).AddMonths(6).Date -Format yyyyMMdd

It seems like your Maven is unable to connect to Maven repository at http://repo1.maven.org/maven2.

If you are using proxy and can access the link with browser the same settings need to be applied to Spring Source Tool Suite (if you are running within suite) or Maven.

For Maven proxy setting create a settings.xml in the .m2 directory with following details

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <proxies>
    <proxy>
      <active>true</active>
      <protocol>http</protocol>
      <host>PROXY</host>
      <port>3120</port>
      <nonProxyHosts>maven</nonProxyHosts>
    </proxy>
  </proxies>
</settings>

If you are not using proxy and can access the link with browser, remove any proxy settings described above.

In Laravel 5.6:

$variable = model_name::find($id);
return view('view')->with ('variable',$variable);

If you just want a light theme and aren't particular about the specific color, then you can pass a theme id to the AlertDialog.Builder constructor.

AlertDialog.Builder(this, AlertDialog.THEME_HOLO_LIGHT)...

or

AlertDialog.Builder(this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT)...

Your find should look like that to avoid sending directory names to sed:

find ./ -type f -exec sed -i -e 's/apple/orange/g' {} \;

People use different tricks to do this. I Googled and find out some results each follow different tricks. Have a look at them:

• Alpha Numeric Sorting in MySQL
• Natural Sorting in MySQL
• Sorting of numeric values mixed with alphanumeric values
• mySQL natural sort
• Natural Sort in MySQL

Edit:

I have just added the code of each link for future visitors.
