Update: Using DateTimeFormat, introduced in java 8:

The idea is to define two formats: one for the input format, and one for the output format. Parse with the input formatter, then format with the output formatter.

Your input format looks quite standard, except the trailing Z. Anyway, let's deal with this: "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'". The trailing 'Z' is the interesting part. Usually there's time zone data here, like -0700. So the pattern would be ...Z, i.e. without apostrophes.

The output format is way more simple: "dd-MM-yyyy". Mind the small y -s.

Here is the example code:

DateTimeFormatter inputFormatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
DateTimeFormatter outputFormatter = DateTimeFormatter.ofPattern("dd-MM-yyy", Locale.ENGLISH);
LocalDate date = LocalDate.parse("2018-04-10T04:00:00.000Z", inputFormatter);
String formattedDate = outputFormatter.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Original answer - with old API SimpleDateFormat

SimpleDateFormat inputFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
SimpleDateFormat outputFormat = new SimpleDateFormat("dd-MM-yyyy");
Date date = inputFormat.parse("2018-04-10T04:00:00.000Z");
String formattedDate = outputFormat.format(date);
System.out.println(formattedDate); // prints 10-04-2018

Do you have your date variable stored as a String or a Date type?

In which case you will need to do something like

DateTime myDate = null;

DateTime.TryParse(myString,myDate);

or

Convert.ToDateTime(myString);

You can then call ToString("dd-MM-yyyy") on your date variable

its pretty simple

  Date someDate = new DateTime();
  string timeOfDay = someDate.ToString("hh:mm tt"); 
  // hh - shows hour and mm - shows minute - tt - shows AM or PM

Something like the following example. Note I'm in Eastern Australia (UTC + 10 hours at the moment).

>>> import datetime
>>> dtnow = datetime.datetime.now();dtutcnow = datetime.datetime.utcnow()
>>> dtnow
datetime.datetime(2010, 8, 4, 9, 33, 9, 890000)
>>> dtutcnow
datetime.datetime(2010, 8, 3, 23, 33, 9, 890000)
>>> delta = dtnow - dtutcnow
>>> delta
datetime.timedelta(0, 36000)
>>> hh,mm = divmod((delta.days * 24*60*60 + delta.seconds + 30) // 60, 60)
>>> hh,mm
(10, 0)
>>> "%s%+02d:%02d" % (dtnow.isoformat(), hh, mm)
'2010-08-04T09:33:09.890000+10:00'
>>>

Easy peasy:

var date = DateTime.Parse("14/11/2011"); // may need some Culture help here
Console.Write(date.ToString("yyyy-MM-dd"));

Take a look at DateTime.ToString() method, Custom Date and Time Format Strings and Standard Date and Time Format Strings

string customFormattedDateTimeString = DateTime.Now.ToString("yyyy-MM-dd");

>>> import time
>>> print(time.strftime('%a %H:%M:%S'))

ASP.NET developers have the choice of this handy built-in (MS JS must be included in page):

var date = Date.parseLocale('20-Mar-2012', 'dd-MMM-yyyy');

http://msdn.microsoft.com/en-us/library/bb397521%28v=vs.100%29.aspx

Try this:

this.TextBox3.Text = String.Format("{0: MM.dd.yyyy}",DateTime.Now);

This seems to work:

declare @d datetime
set @d = '2014-04-17 13:55:12'

select replace(convert(varchar(8), @d, 112)+convert(varchar(8), @d, 114), ':','') 

Result:

20140417135512

You can chain your wheres directly, without function(q). There's also a nice date handling package in laravel, called Carbon. So you could do something like:

$projects = Project::where('recur_at', '>', Carbon::now())
    ->where('recur_at', '<', Carbon::now()->addWeek())
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();

Just make sure you require Carbon in composer and you're using Carbon namespace (use Carbon\Carbon;) and it should work.

EDIT: As Joel said, you could do:

$projects = Project::whereBetween('recur_at', array(Carbon::now(), Carbon::now()->addWeek()))
    ->where('status', '<', 5)
    ->where('recur_cancelled', '=', 0)
    ->get();

You can make a path for your file as bellow:

string path = "fileName-"+DateTime.Now.ToString("yyyy-dd-M--HH-mm-ss") + ".txt";

You should set a TimeZone in your DateFormat, otherwise it will use the default one (depending on the settings of the computer).

DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy MM dd");
String text = date.toString(formatter);
LocalDate date = LocalDate.parse(text, formatter);

I believe this might help, you may need to use some sort of localdate variation instead of instant

Thanks Darin, For me, to be able to post to the create method, It only worked after I modified the BindModel code to :

public override object BindModel(ControllerContext controllerContext, ModelBindingContext bindingContext)
{
    var displayFormat = bindingContext.ModelMetadata.DisplayFormatString;
    var value = bindingContext.ValueProvider.GetValue(bindingContext.ModelName);

    if (!string.IsNullOrEmpty(displayFormat) && value != null)
    {
        DateTime date;
        displayFormat = displayFormat.Replace("{0:", string.Empty).Replace("}", string.Empty);
        // use the format specified in the DisplayFormat attribute to parse the date
         if (DateTime.TryParse(value.AttemptedValue, CultureInfo.GetCultureInfo("en-GB"), DateTimeStyles.None, out date))
        {
            return date;
        }
        else
        {
            bindingContext.ModelState.AddModelError(
                bindingContext.ModelName,
                string.Format("{0} is an invalid date format", value.AttemptedValue)
            );
        }
    }

    return base.BindModel(controllerContext, bindingContext);
}

Hope this could help someone else...

After PHP 5 you can use this: echo date("c"); form ISO 8601 formatted datetime.

http://ideone.com/nD7piL

Note for comments:

Regarding to this, both of these expressions are valid for timezone, for basic format: ±[hh]:[mm], ±[hh][mm], or ±[hh].

But note that, +0X:00 is correct, and +0X00 is incorrect for extended usage. So it's better to use date("c"). A similar discussion here.

Another way to address the timezone issue if you want to set the default timezone for the entire script to a certian timezone is to use date_default_timezone_set() then use one of the supported timezones.

Expanding on retrography's answer..: I had this same problem even when using LocalDate and not LocalDateTime. The issue was that I had created my DateTimeFormatter using .withResolverStyle(ResolverStyle.STRICT);, so I had to use date pattern uuuuMMdd instead of yyyyMMdd (i.e. "year" instead of "year-of-era")!

DateTimeFormatter formatter = new DateTimeFormatterBuilder()
  .parseStrict()
  .appendPattern("uuuuMMdd")
  .toFormatter()
  .withResolverStyle(ResolverStyle.STRICT);
LocalDate dt = LocalDate.parse("20140218", formatter);

(This solution was originally a comment to retrography's answer, but I was encouraged to post it as a stand-alone answer because it apparently works really well for many people.)

Most of these answers have milliseconds / microseconds which clearly isn't supported by ISO 8601. The correct answer would be:

System.DateTime.Now.ToString("yyyy-MM-ddTHH:mm:ssK");
// or
System.DateTime.Now.ToUniversalTime().ToString("yyyy-MM-ddTHH:mm:ssK");

References:

• ISO 8601 specification
• "K" Specifier

You can create your own custom validation method using the addMethod function. Say you wanted to validate "dd/mm/yyyy":

$.validator.addMethod(
    "australianDate",
    function(value, element) {
        // put your own logic here, this is just a (crappy) example
        return value.match(/^\d\d?\/\d\d?\/\d\d\d\d$/);
    },
    "Please enter a date in the format dd/mm/yyyy."
);

And then on your form add:

$('#myForm')
    .validate({
        rules : {
            myDate : {
                australianDate : true
            }
        }
    })
;

Try this.

 var dateAsString = DateTime.Now.ToString("dd/MM/yyyy");
// dateAsString = "09/07/2013"

and also check this link for more formatting data and time

All solutions here doesn't really bind the model to the input because you will have to change back the dateAsString to be saved as date in your object (in the controller after the form will be submitted).

If you don't need the binding effect, but just to show it in the input,

a simple could be:

<input type="date" value="{{ item.date | date: 'yyyy-MM-dd' }}" id="item_date" />

Then, if you like, in the controller, you can save the edited date in this way:

  $scope.item.date = new Date(document.getElementById('item_date').value).getTime();

be aware: in your controller, you have to declare your item variable as $scope.item in order for this to work.

If you have a mixture of formats in your date, don't forget to set infer_datetime_format=True to make life easier.

df['date'] = pd.to_datetime(df['date'], infer_datetime_format=True)

Source: pd.to_datetime

or if you want a customized approach:

def autoconvert_datetime(value):
    formats = ['%m/%d/%Y', '%m-%d-%y']  # formats to try
    result_format = '%d-%m-%Y'  # output format
    for dt_format in formats:
        try:
            dt_obj = datetime.strptime(value, dt_format)
            return dt_obj.strftime(result_format)
        except Exception as e:  # throws exception when format doesn't match
            pass
    return value  # let it be if it doesn't match

df['date'] = df['date'].apply(autoconvert_datetime)

Since the question was "display" :

@Html.ValueFor(model => model.RegistrationDate, "{0:dd/MM/yyyy}")

Example of calculating time:

work-start   work-stop   lunchbreak    effective time

  07:30:00    17:00:00          1.5                 8  [=((A2-A1)*24)-A3]

If you subtract one time value from another the result you get will represent the fraction of 24 hours, so if you multiply the result with 24 you get the value represented in hours.

In other words: the operation is mutiply, but the meaning is to change the format of the number (from days to hours).

>>> from datetime import datetime
>>> dt = datetime.now().strftime("%Y-%m-%d %X")
>>> print(dt)
'2021-02-05 04:10:24'

You should be using datetime.datetime.strptime. Note that very old versions of Python (2.4 and older) don't have datetime.datetime.strptime; use time.strptime in that case.

EDIT: Okay, so you don't want your local time (which isn't Australia) to contribute to the result, but instead the Australian time zone. Your existing code should be absolutely fine then, although Sydney is currently UTC+11, not UTC+10.. Short but complete test app:

import java.util.*;
import java.text.*;

public class Test {
    public static void main(String[] args) throws InterruptedException {
        Date date = new Date(1318386508000L);
        DateFormat format = new SimpleDateFormat("dd/MM/yyyy HH:mm:ss");
        format.setTimeZone(TimeZone.getTimeZone("Etc/UTC"));
        String formatted = format.format(date);
        System.out.println(formatted);
        format.setTimeZone(TimeZone.getTimeZone("Australia/Sydney"));
        formatted = format.format(date);
        System.out.println(formatted);
    }
}

Output:

12/10/2011 02:28:28
12/10/2011 13:28:28

I would also suggest you start using Joda Time which is simply a much nicer date/time API...

EDIT: Note that if your system doesn't know about the Australia/Sydney time zone, it would show UTC. For example, if I change the code about to use TimeZone.getTimeZone("blah/blah") it will show the UTC value twice. I suggest you print TimeZone.getTimeZone("Australia/Sydney").getDisplayName() and see what it says... and check your code for typos too :)

Long serverUptimeSeconds = 
    (System.currentTimeMillis() - SINCE_TIME_IN_MILLISECONDS) / 1000;


String serverUptimeText = 
String.format("%d days %d hours %d minutes %d seconds",
serverUptimeSeconds / 86400,
( serverUptimeSeconds % 86400) / 3600 ,
((serverUptimeSeconds % 86400) % 3600 ) / 60,
((serverUptimeSeconds % 86400) % 3600 ) % 60
);

TempData is a bucket where you can dump data that is only needed for the following request. That is, anything you put into TempData is discarded after the next request completes. This is useful for one-time messages, such as form validation errors. The important thing to take note of here is that this applies to the next request in the session, so that request can potentially happen in a different browser window or tab.

To answer your specific question: there's no right way to use it. It's all up to usability and convenience. If it works, makes sense and others are understanding it relatively easy, it's good. In your particular case, the passing of a parameter this way is fine, but it's strange that you need to do that (code smell?). I'd rather keep a value like this in resources (if it's a resource) or in the database (if it's a persistent value). From your usage, it seems like a resource, since you're using it for the page title.

Hope this helps.

After studying the answer from Serhil, I created a pod UINavigationBar+Addition that can easily hide the hairline.

If you are using windows 7 64-bit version, then the solution is found here: http://pypi.python.org/pypi/setuptools

namely, you need to download a python script, run it, and then easy_install will work normally from commandline.

P.S. I agree with the original poster saying that this should work out of the box.

In addition to solutions proposed, and in case you have a 1D range to 1D array, i prefer to process it through a function like below. The reason is simple: If for any reason your range is reduced to 1 element range, as far as i know the command Range().Value will not return a variant array but just a variant and you will not be able to assign a variant variable to a variant array (previously declared).

I had to convert a variable size range to a double array, and when the range was of 1 cell size, i was not able to use a construct like range().value so i proceed with a function like below.

Public Function Rng2Array(inputRange As Range) As Double()

    Dim out() As Double    
    ReDim out(inputRange.Columns.Count - 1)

    Dim cell As Range
    Dim i As Long
    For i = 0 To inputRange.Columns.Count - 1
        out(i) = inputRange(1, i + 1) 'loop over a range "row"
    Next

    Rng2Array = out  
End Function

Yea, it's bad...

== means that your two string references are exactly the same object. You may have heard that this is the case because Java keeps sort of a literal table (which it does), but that is not always the case. Some strings are loaded in different ways, constructed from other strings, etc., so you must never assume that two identical strings are stored in the same location.

Equals does the real comparison for you.

You can use RVM(Ruby version manager) which helps in managing all versions of ruby on your machine , which is very helpful for you development (when migrating to unstable release to stable release )

or for Linux (ubuntu) go for sudo apt-get install ruby1.8-dev

then sudo gem install rails to verify it do rails -v it will show version on rails

after that you can install bundles (required gems for development)

I would add something to the solution of leonvian, so if by any chance the string is not found among the resources (return value 0, that is not a valid resource code), the function might return something :

private String getStringResourceByName(String aString) {
    String packageName = getPackageName();
    int resId = getResources()
            .getIdentifier(aString, "string", packageName);
    if (resId == 0) {
        return aString;
    } else {
        return getString(resId);
    }
}

Just use that:

var myDateUtc = DateTime.SpecifyKind(DateTime.Parse("Tue, 1 Jan 2008 00:00:00"), DateTimeKind.Utc);

if (myDateUtc.Kind == DateTimeKind.Utc)
{
     Console.WriteLine("Yes. I am UTC!");
}

You can test this code using the online c# compiler:

I hope it helps.

Not answering the question directly, but it might help someone else.

I have a column called Volume, having both - (invalid/NaN) and numbers formatted with ,

df['Volume'] = df['Volume'].astype('str')
df['Volume'] = df['Volume'].str.replace(',', '')
df['Volume'] = pd.to_numeric(df['Volume'], errors='coerce')

Casting to string is required for it to apply to str.replace

pandas.Series.str.replace
pandas.to_numeric

I would counsel against using if ($hash{$key}) since it will not do what you expect if the key exists but its value is zero or empty.

I have improved on the solution above by providing support for different log levels and by changing the log levels automatically depending on if the code is being run on a live device or on the emulator.

    } else {
        LOG_LEVEL = INFO;
    }

}

I think jQuery cannot find the element.

First of all find the element

var rowTemplate= document.getElementsByName("rowTemplate");

or

var rowTemplate = document.getElementById("rowTemplate"); 

or

var rowTemplate = $('#rowTemplate');

Then try your code again

rowTemplate.html().replace(....)

Yes, you can use Arrays.copyOfRange

It does about the same thing (note there is a copy : you don't change the initial array).

SELECT <...>
FROM A.table1 t1 JOIN B.table2 t2 ON t2.column2 = t1.column1;

Just make sure that in the SELECT line you specify which table columns you are using, either by full reference, or by alias. Any of the following will work:

SELECT *
SELECT t1.*,t2.column2
SELECT A.table1.column1, t2.*
etc.

There are a few arguments (one of which is relatively recent) which I believe contradict Bjarne's position on this.

1. Documentation of intent

   Using NULL allows for searches on its use and it also highlights that the developer wanted to use a NULL pointer, irrespective of whether it is being interpreted by the compiler as NULL or not.

2. Overload of pointer and 'int' is relatively rare

   The example that everybody quotes is:

    void foo(int*);
    void foo (int);
   
    void bar() {
      foo (NULL);  // Calls 'foo(int)'
    }
   

   However, at least in my opinion, the problem with the above is not that we're using NULL for the null pointer constant: it's that we have overloads of foo() which take very different kinds of arguments. The parameter must be an int too, as any other type will result in an ambiguous call and so generate a helpful compiler warning.

3. Analysis tools can help TODAY!

   Even in the absence of C++0x, there are tools available today that verify that NULL is being used for pointers, and that 0 is being used for integral types.

4. C++ 11 will have a new std::nullptr_t type.

   This is the newest argument to the table. The problem of 0 and NULL is being actively addressed for C++0x, and you can guarantee that for every implementation that provides NULL, the very first thing that they will do is:

    #define NULL  nullptr
   

   For those who use NULL rather than 0, the change will be an improvement in type-safety with little or no effort - if anything it may also catch a few bugs where they've used NULL for 0. For anybody using 0 today... well, hopefully they have a good knowledge of regular expressions...

Where I work we have been using this method on all of our repositories for a few years without any problems (except when we create a new repository and forget to set it up this way):

1. Set 'sharedRepository = true' in the config file's '[core]' section.

2. Change the group id of the repository to a group shared by all users who are allowed to push to it:

   chgrp -R shared_group /git/our_repos
   chmod -R g+w /git/our_repos
   

3. Set the setgid bit on all directories in the repository so that new files/directories keep the same group:

   find /git/our_repos -type d -exec chmod g+s {} +
   

4. Add this line to the pre-receive hook in the repository to ensure new file permissions allow group read/write:

   umask 007

You can do this with a custom action. You can add a refrence to your custom action under <InstallExecuteSequence>:

<InstallExecuteSequence>
...
  <Custom Action="FileCleaner" After='InstallFinalize'>
          Installed AND NOT UPGRADINGPRODUCTCODE</Custom>

Then you will also have to define your Action under <Product>:

<Product> 
...
  <CustomAction Id='FileCleaner' BinaryKey='FileCleanerEXE' 
                ExeCommand='' Return='asyncNoWait'  />

Where FileCleanerEXE is a binary (in my case a little c++ program that does the custom action) which is also defined under <Product>:

<Product> 
...
  <Binary Id="FileCleanerEXE" SourceFile="path\to\fileCleaner.exe" />

The real trick to this is the Installed AND NOT UPGRADINGPRODUCTCODE condition on the Custom Action, with out that your action will get run on every upgrade (since an upgrade is really an uninstall then reinstall). Which if you are deleting files is probably not want you want during upgrading.

On a side note: I recommend going through the trouble of using something like C++ program to do the action, instead of a batch script because of the power and control it provides -- and you can prevent the "cmd prompt" window from flashing while your installer runs.

It sounds like you need to create a wrapper around an instance you can invalidate:

public class Ref<T> where T : class
{
    private T instance;
    public Ref(T instance)
    {
        this.instance = instance;
    }

    public static implicit operator Ref<T>(T inner)
    {
        return new Ref<T>(inner);
    }

    public void Delete()
    {
        this.instance = null;
    }

    public T Instance
    {
        get { return this.instance; }
    }
}

and you can use it like:

Ref<Car> carRef = new Car();
carRef.Delete();
var car = carRef.Instance;     //car is null

Be aware however that if any code saves the inner value in a variable, this will not be invalidated by calling Delete.

Full version:

<? echo date('F Y'); ?>

Short version:

<? echo date('M Y'); ?>

Here is a good reference for the different date options.

update

To show the previous month we would have to introduce the mktime() function and make use of the optional timestamp parameter for the date() function. Like this:

echo date('F Y', mktime(0, 0, 0, date('m')-1, 1, date('Y')));

This will also work (it's typically used to get the last day of the previous month):

echo date('F Y', mktime(0, 0, 0, date('m'), 0, date('Y')));

Hope that helps.

Queue in Java is defined as an interface and many ready-to-use implementation is present as part of JDK release. Here are some: LinkedList, Priority Queue, ArrayBlockingQueue, ConcurrentLinkedQueue, Linked Transfer Queue, Synchronous Queue etc.

SO You can create any of these class and hold it as Queue reference. for example

import java.util.LinkedList;
import java.util.Queue;

public class QueueExample {

 public static void main (String[] args) {
  Queue que = new LinkedList();
  que.add("first");
  que.offer("second");
  que.offer("third");
  System.out.println("Queue Print:: " + que);
  
  String head = que.element();
  System.out.println("Head element:: " + head);
  
  String element1 = que.poll();
  System.out.println("Removed Element:: " + element1);
  
  System.out.println("Queue Print after poll:: " + que);
  String element2 = que.remove();
  System.out.println("Removed Element:: " + element2);
  
  System.out.println("Queue Print after remove:: " + que);  
 }
}

You can also implement your own custom Queue implementing Queue interface.

<script>
         arr = []
         arr[0] = "ab"
         arr[1] = "abcdefgh"
         arr[2] = "sdfds"
         arr.sort(function(a,b){
            return a.length<b.length
         })
         document.write(arr)

</script>

The anonymous function that you pass to sort tells it how to sort the given array.hope this helps.I know this is confusing but you can tell the sort function how to sort the elements of the array by passing it a function as a parameter telling it what to do

This was just another solution but different than the rest.

function diffArray(arr1, arr2) {
  var newArr = arr1.concat(arr2);
  newArr.sort();
  var finalArr = [];
  for(var i = 0;i<newArr.length;i++) {
   if(!(newArr[i] === newArr[i+1] || newArr[i] === newArr[i-1])) {
     finalArr.push(newArr[i]);
   } 
  }
  return finalArr;
}

if (yourObject instanceof yourClassName) will evaluate to false if yourObject is null.

box-shadow: inset 1px 2000px rgba(208, 208, 208, 0.54);

I had this problem and after check my code line by line i saw this

 <textarea class="form-control" type="text" ng-model="WallDesc" placeholder="Enter Your Description"/>

i just changed it to

     <textarea class="form-control" type="text" ng-model="WallDesc" placeholder="Enter Your Description"></textarea>

and it's worked. so check your tags.

Because the accepted answer isn't on the same planet as BS3, I'll share what I'm using to achieve nearly full-width capabilities.

First off, this is cheating. It's not really fluid width - but it appears to be - depending on the size of the screen viewing the site.

The problem with BS3 and fluid width sites is that they have taken this "mobile first" approach, which requires that they define every freaking screen width up to what they consider to be desktop (1200px) I'm working on a laptop with a 1900px wide screen - so I end up with 350px on either side of the content at what BS3 thinks is a desktop sized width.

They have defined 10 screen widths (really only 5, but anyway). I don't really feel comfortable changing those, because they are common widths. So, I chose to define some extra widths for BS to choose from when deciding the width of the container class.

The way I use BS is to take all of the Bootstrap provided LESS files, omit the variables.less file to provide my own, and add one of my own to the end to override the things I want to change. Within my less file, I add the following to achieve 2 common screen width settings:

@media screen and (min-width: 1600px) {
    .container {
        max-width: (1600px - @grid-gutter-width);
    }
}
@media screen and (min-width: 1900px) {
    .container {
        max-width: (1900px - @grid-gutter-width);
    }
}

These two settings set the example for what you need to do to achieve different screen widths. Here, you get full width at 1600px, and 1900px. Any less than 1600 - BS falls back to the 1200px width, then to 768px and so forth - down to phone size.

If you have larger to support, just create more @media screen statements like these. If you're building the CSS instead, you'll want to determine what gutter width was used and subtract it from your target screen width.

Update:

Bootstrap 3.0.1 and up (so far) - it's as easy as setting @container-large-desktop to 100%

myList.setOnItemClickListener(new OnItemClickListener() {
  public void onItemClick(AdapterView<?> adapter, View v, int position, long id) {
      MyClass selItem = (MyClass) adapter.getItem(position);
   }
}

You're missing service name:

 SQL> connect username/password@hostname:port/SERVICENAME

EDIT

If you can connect to the database from other computer try running there:

select sys_context('USERENV','SERVICE_NAME') from dual

and

select sys_context('USERENV','SID') from dual

One quick and easy way:

function paintSvgToCanvas(uSvg, uCanvas) {

    var pbx = document.createElement('img');

    pbx.style.width  = uSvg.style.width;
    pbx.style.height = uSvg.style.height;

    pbx.src = 'data:image/svg+xml;base64,' + window.btoa(uSvg.outerHTML);
    uCanvas.getContext('2d').drawImage(pbx, 0, 0);

}

You can't use UIImagePickerController, but you can use a custom image picker. I think ELCImagePickerController is the best option, but here are some other libraries you could use:

Objective-C
1. ELCImagePickerController
2. WSAssetPickerController
3. QBImagePickerController
4. ZCImagePickerController
5. CTAssetsPickerController
6. AGImagePickerController
7. UzysAssetsPickerController
8. MWPhotoBrowser
9. TSAssetsPickerController

Thanx to @androidbloke,
I have added some library that I know for multiple image picker in swift.
Will update list as I find new ones.
Thank You.

This is not a PowerShell-specific answer, but you could authenticate against the share using "NET USE" first:

net use \\server\share /user:<domain\username> <password>

And then do whatever you need to do in PowerShell...

Using find with bind to pass specific key values to a callback function.

   function byValue(o) { 
       return o.a === this.a && o.b === this.b; 
   };   

   var result = jsObjects.find(byValue.bind({ a: 5, b: 6 }));

Edit - 20 March 2016

Mongoose now support timestamps for collections.

Please consider the answer of @bobbyz below. Maybe this is what you are looking for.

Original answer

Mongoose supports a Date type (which is basically a timestamp):

time : { type : Date, default: Date.now }

With the above field definition, any time you save a document with an unset time field, Mongoose will fill in this field with the current time.

Source: http://mongoosejs.com/docs/guide.html

Since you tagged Java-ee as well - then YES it is possible.

and in core java as well it is possible using static blocks

and check this How can you run a Java program without main method?

Edit:
as already pointed out in other answers - it does not support from Java 7

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

Not sure what you are trying to do, but you have two select clauses. Do this instead:

SELECT * 
FROM ( SELECT * 
       FROM orders_products 
       INNER JOIN orders ON orders_products.orders_id = orders.orders_id 
       WHERE products_id = 181) AS A
JOIN ( SELECT * 
       FROM orders_products 
       INNER JOIN orders ON orders_products.orders_id = orders.orders_id
       WHERE products_id = 180) AS B

ON A.orders_id=B.orders_id

Update:

You could probably reduce it to something like this:

SELECT o.orders_id, 
       op1.products_id, 
       op1.quantity, 
       op2.products_id, 
       op2.quantity
FROM orders o
INNER JOIN orders_products op1 on o.orders_id = op1.orders_id  
INNER JOIN orders_products op2 on o.orders_id = op2.orders_id  
WHERE op1.products_id = 180
AND op2.products_id = 181

Another way to tell it "Yesterday"...

Select * from TABLE
where Day(DateField) = (Day(GetDate())-1)
and Month(DateField) = (Month(GetDate()))
and Year(DateField) = (Year(getdate()))

This conceivably won't work well on January 1, as well as the first day of every month. But on the fly it's effective.

If the DC is Win2k3 SP2 or above, you can use something like:

(&(objectCategory=user)(memberOf:1.2.840.113556.1.4.1941:=CN=GroupOne,OU=Security Groups,OU=Groups,DC=example,DC=com))

to get the nested group membership.

Source: https://ldapwiki.com/wiki/Active%20Directory%20Group%20Related%20Searches

<script type="text/javascript">
var _initial = '2015-05-21T10:17:28.593Z';
var fromTime = new Date(_initial);
var toTime = new Date();

var differenceTravel = toTime.getTime() - fromTime.getTime();
var seconds = Math.floor((differenceTravel) / (1000));
document.write('+ seconds +');
</script>

It can be resolved as follows:

Go to Project properties.

Then 'Java Compiler' -> Check the box ('Enable project specific settings')

Change the compiler compliance level to '5.0' & click ok

Select the checkbox for "Use default compliance settings"

A good option is AutoTable(a Table plugin for jsPDF), it includes themes, rowspan, colspan, extract data from html, works with json, you can also personalize your headers and make them horizontals. Here is a demo.

The url you are referring is a query type and I see that the request object supports a method called arguments to get the query arguments. You may also want try self.request.get('def') directly to get your value from the object..

I met the same problem yesterday.And I fixed already. Please follow the steps:

• Run setup.exe again; Change or Remove Microsoft Visual Studio 2010; Upgrade license Key (Enter new license key); Complete.

GOOD LUCK !

The most simple and used by everyone mostly is javascript:void(0) You can use it instead of using # to stop tag redirect to header section.

<a href="javascript:void(0)" onclick="testFunction();">Click To check Function</a>

function testFunction() {
    alert("hello world");
}

It doesn't make a lot of sense, the original GAC was already quite capable of storing different versions of assemblies. And there's little reason to assume a program will ever accidentally reference the wrong assembly, all the .NET 4 assemblies got the [AssemblyVersion] bumped up to 4.0.0.0. The new in-process side-by-side feature should not change this.

My guess: there were already too many .NET projects out there that broke the "never reference anything in the GAC directly" rule. I've seen it done on this site several times.

Only one way to avoid breaking those projects: move the GAC. Back-compat is sacred at Microsoft.

From http://docs.python.org/library/csv.html#csv.writer:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with statement to close the file when you're done writing to it.
Tested example below:

from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']
with open('file3.csv','wb') as fou: # note: 'wb' instead of 'w'
    output = csv.DictWriter(fou,delimiter=',',fieldnames=headers)
    output.writerow(dict((fn,fn) for fn in headers))
    output.writerows(rows)

As @jethro said, splitext is the neat way to do it. But in this case, it's pretty easy to split it yourself, since the extension must be the part of the filename coming after the final period:

filename = '/home/user/somefile.txt'
print( filename.rsplit( ".", 1 )[ 0 ] )
# '/home/user/somefile'

The rsplit tells Python to perform the string splits starting from the right of the string, and the 1 says to perform at most one split (so that e.g. 'foo.bar.baz' -> [ 'foo.bar', 'baz' ]). Since rsplit will always return a non-empty array, we may safely index 0 into it to get the filename minus the extension.

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

There is a package matrixStats that provides some functions to do column and row summaries, see in the package vignette, but you have to convert your data.frame into a matrix.

Then you run: colMaxs(as.matrix(ozone))

Yes, there is: https://github.com/robinrowe/libunistd

Clone the repository and add path\to\libunistd\unistd to the INCLUDE environment variable.

Even better are f-strings in python 3!

f = open(f'{name}.csv', 'wb')

public static void main(String[] args) {

    DateTimeFormatter DATE_TIME_FORMATTER = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss")
            .withZone(ZoneId.systemDefault());

    System.out.println(DATE_TIME_FORMATTER.format(new Date().toInstant()));

}

I also get this when using the HTTPS everywhere plugin. This plugin has a list of sites that also have https instead of http. So I assume before the actual request is made it is already being cancelled somehow.

So for example when I go to http://stackexchange.com, in Developer I first see a request with status (terminated). This request has some headers, but only the GET, User-Agent, and Accept. No response as well.

Then there is request to https://stackexchange.com with full headers etc.

So I assume it is used for requests that aren't sent.

Here is my simple solution using Jquery filters.

$('#publisher').on('change', function(e) {
   let selector = $(this).val();
   $("#site > option").hide();
   $("#site > option").filter(function(){return $(this).data('pub') == selector}).show();
});

JSFIDDLE

In addition to what other have said, you may also be interested to know that what in does is to call the list.__contains__ method, that you can define on any class you write and can get extremely handy to use python at his full extent.  

A dumb use may be:

>>> class ContainsEverything:
    def __init__(self):
        return None
    def __contains__(self, *elem, **k):
        return True


>>> a = ContainsEverything()
>>> 3 in a
True
>>> a in a
True
>>> False in a
True
>>> False not in a
False
>>>         

It's not really an anwser but a workaround to open a local link in chrome using python.

Copy the local link you want to run then run the code bellow (using a shortcut), it will open your link.

import win32clipboard
import os

win32clipboard.OpenClipboard()
clipboard_data= win32clipboard.GetClipboardData()
win32clipboard.CloseClipboard()

os.system("start "+clipboard_data)

Else you can get id of process your application runs in:

final static int android.os.Process.myPid()
Returns the identifier of this process, which can be used with killProcess(int) and sendSignal(int, int).

For anyone trying to use jQuery.active with JSONP requests (like I was) you'll need enable it with this:

jQuery.ajaxPrefilter(function( options ) {
    options.global = true;
});

Keep in mind that you'll need a timeout on your JSONP request to catch failures.

This is another solution:

return {
  Field1 : "ASD",
  Field2 : "QWE" 
} as myClass;

You can use Theme.applyStyle to modify your theme at runtime by applying another style to it.

Let's say you have these style definitions:

<style name="DefaultTheme" parent="Theme.AppCompat.Light">
    <item name="colorPrimary">@color/md_lime_500</item>
    <item name="colorPrimaryDark">@color/md_lime_700</item>
    <item name="colorAccent">@color/md_amber_A400</item>
</style>

<style name="OverlayPrimaryColorRed">
    <item name="colorPrimary">@color/md_red_500</item>
    <item name="colorPrimaryDark">@color/md_red_700</item>
</style>

<style name="OverlayPrimaryColorGreen">
    <item name="colorPrimary">@color/md_green_500</item>
    <item name="colorPrimaryDark">@color/md_green_700</item>
</style>

<style name="OverlayPrimaryColorBlue">
    <item name="colorPrimary">@color/md_blue_500</item>
    <item name="colorPrimaryDark">@color/md_blue_700</item>
</style>

Now you can patch your theme at runtime like so:

getTheme().applyStyle(R.style.OverlayPrimaryColorGreen, true);

The method applyStylehas to be called before the layout gets inflated! So unless you load the view manually you should apply styles to the theme before calling setContentView in your activity.

Of course this cannot be used to specify an arbitrary color, i.e. one out of 16 million (256³) colors. But if you write a small program that generates the style definitions and the Java code for you then something like one out of 512 (8³) should be possible.

What makes this interesting is that you can use different style overlays for different aspects of your theme. Just add a few overlay definitions for colorAccent for example. Now you can combine different values for primary color and accent color almost arbitrarily.

You should make sure that your overlay theme definitions don't accidentally inherit a bunch of style definitions from a parent style definition. For example a style called AppTheme.OverlayRed implicitly inherits all styles defined in AppTheme and all these definitions will also be applied when you patch the master theme. So either avoid dots in the overlay theme names or use something like Overlay.Red and define Overlay as an empty style.

You may use the == operator to compare unicode objects for equality.

>>> s1 = u'Hello'
>>> s2 = unicode("Hello")
>>> type(s1), type(s2)
(<type 'unicode'>, <type 'unicode'>)
>>> s1==s2
True
>>> 
>>> s3='Hello'.decode('utf-8')
>>> type(s3)
<type 'unicode'>
>>> s1==s3
True
>>> 

But, your error message indicates that you aren't comparing unicode objects. You are probably comparing a unicode object to a str object, like so:

>>> u'Hello' == 'Hello'
True
>>> u'Hello' == '\x81\x01'
__main__:1: UnicodeWarning: Unicode equal comparison failed to convert both arguments to Unicode - interpreting them as being unequal
False

See how I have attempted to compare a unicode object against a string which does not represent a valid UTF8 encoding.

Your program, I suppose, is comparing unicode objects with str objects, and the contents of a str object is not a valid UTF8 encoding. This seems likely the result of you (the programmer) not knowing which variable holds unicide, which variable holds UTF8 and which variable holds the bytes read in from a file.

I recommend http://nedbatchelder.com/text/unipain.html, especially the advice to create a "Unicode Sandwich."

Short 'n Sweet

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Example

escapeRegExp("All of these should be escaped: \ ^ $ * + ? . ( ) | { } [ ]");

>>> "All of these should be escaped: \\ \^ \$ \* \+ \? \. \( \) \| \{ \} \[ \] "

(NOTE: the above is not the original answer; it was edited to show the one from MDN. This means it does not match what you will find in the code in the below npm, and does not match what is shown in the below long answer. The comments are also now confusing. My recommendation: use the above, or get it from MDN, and ignore the rest of this answer. -Darren,Nov 2019)

The Long Answer

If you're going to use the function above at least link to this stack overflow post in your code's documentation so that it doesn't look like crazy hard-to-test voodoo.

var escapeRegExp;

(function () {
  // Referring to the table here:
  // https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/regexp
  // these characters should be escaped
  // \ ^ $ * + ? . ( ) | { } [ ]
  // These characters only have special meaning inside of brackets
  // they do not need to be escaped, but they MAY be escaped
  // without any adverse effects (to the best of my knowledge and casual testing)
  // : ! , = 
  // my test "~!@#$%^&*(){}[]`/=?+\|-_;:'\",<.>".match(/[\#]/g)

  var specials = [
        // order matters for these
          "-"
        , "["
        , "]"
        // order doesn't matter for any of these
        , "/"
        , "{"
        , "}"
        , "("
        , ")"
        , "*"
        , "+"
        , "?"
        , "."
        , "\\"
        , "^"
        , "$"
        , "|"
      ]

      // I choose to escape every character with '\'
      // even though only some strictly require it when inside of []
    , regex = RegExp('[' + specials.join('\\') + ']', 'g')
    ;

  escapeRegExp = function (str) {
    return str.replace(regex, "\\$&");
  };

  // test escapeRegExp("/path/to/res?search=this.that")
}());

DESCRIPTION: SC is a command line program used for communicating with the NT Service Controller and services. USAGE: sc [command] [service name] ...

    The option <server> has the form "\\ServerName"
    Further help on commands can be obtained by typing: "sc [command]"
    Commands:
      query-----------Queries the status for a service, or
                      enumerates the status for types of services.
      queryex---------Queries the extended status for a service, or
                      enumerates the status for types of services.
      start-----------Starts a service.
      pause-----------Sends a PAUSE control request to a service.
      interrogate-----Sends an INTERROGATE control request to a service.
      continue--------Sends a CONTINUE control request to a service.
      stop------------Sends a STOP request to a service.
      config----------Changes the configuration of a service (persistant).
      description-----Changes the description of a service.
      failure---------Changes the actions taken by a service upon failure.
      qc--------------Queries the configuration information for a service.
      qdescription----Queries the description for a service.
      qfailure--------Queries the actions taken by a service upon failure.
      delete----------Deletes a service (from the registry).
      create----------Creates a service. (adds it to the registry).
      control---------Sends a control to a service.
      sdshow----------Displays a service's security descriptor.
      sdset-----------Sets a service's security descriptor.
      GetDisplayName--Gets the DisplayName for a service.
      GetKeyName------Gets the ServiceKeyName for a service.
      EnumDepend------Enumerates Service Dependencies.

    The following commands don't require a service name:
    sc <server> <command> <option>
      boot------------(ok | bad) Indicates whether the last boot should
                      be saved as the last-known-good boot configuration
      Lock------------Locks the Service Database
      QueryLock-------Queries the LockStatus for the SCManager Database

EXAMPLE: sc start MyService

Two options:

• Return default(T) which means you'll return null if T is a reference type (or a nullable value type), 0 for int, '\0' for char, etc. (Default values table (C# Reference))
• Restrict T to be a reference type with the where T : class constraint and then return null as normal

$("label[for='"+$(this).attr("id")+"']");

This should allow you to select labels for all the fields in a loop as well. All you need to ensure is your labels should say for='FIELD' where FIELD is the id of the field for which this label is being defined.

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

Web applications require more memory, presumably because you have no choice but to compile into a single assembly. I just converted a large legacy site to a web application and have issues with running out of memory, both at compile time with the error message as below :

Unexpected error writing metadata to file '' -- 
Not enough storage is available to complete this operation. 

error, and at runtime with this error message as below :

Exception information: 
    Exception type: HttpException 
    Exception message: Exception of type 'System.OutOfMemoryException' was thrown.
   at System.Web.Compilation.BuildManager.ReportTopLevelCompilationException()

My recommendation for converting larger sites on memory-constrained legacy hardware is, to choose the option to revert back to the web site model. Even after an initial success problem might creep up later.

For this problem, I have finally put a new <i> tag to refresh the select instead. Don't try to trigger an event if the selected option is the same that the one already selected.

If user click on the "refresh" button, I trigger the onchange event of my select with :

const refreshEquipeEl = document.getElementById("refreshEquipe1");

function onClickRefreshEquipe(event){
    let event2 = new Event('change');
    equipesSelectEl.dispatchEvent(event2);
}
refreshEquipeEl.onclick = onClickRefreshEquipe;

This way, I don't need to try select the same option in my select.

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

As martijn-courteaux said, create a custom component it's the better option. In C# exists a component called PictureBox and I tried to create this component for Java, here is the code:

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JComponent;

public class JPictureBox extends JComponent {

    private Icon icon = null;
    private final Dimension dimension = new Dimension(100, 100);
    private Image image = null;
    private ImageIcon ii = null;
    private SizeMode sizeMode = SizeMode.STRETCH;
    private int newHeight, newWidth, originalHeight, originalWidth;

    public JPictureBox() {
        JPictureBox.this.setPreferredSize(dimension);
        JPictureBox.this.setOpaque(false);
        JPictureBox.this.setSizeMode(SizeMode.STRETCH);
    }

    @Override
    public void paintComponent(Graphics g) {
        if (ii != null) {
            switch (getSizeMode()) {
                case NORMAL:
                    g.drawImage(image, 0, 0, ii.getIconWidth(), ii.getIconHeight(), null);
                    break;
                case ZOOM:
                    aspectRatio();
                    g.drawImage(image, 0, 0, newWidth, newHeight, null);
                    break;
                case STRETCH:
                    g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
                    break;
                case CENTER:
                    g.drawImage(image, (int) (this.getWidth() / 2) - (int) (ii.getIconWidth() / 2), (int) (this.getHeight() / 2) - (int) (ii.getIconHeight() / 2), ii.getIconWidth(), ii.getIconHeight(), null);
                    break;
                default:
                    g.drawImage(image, 0, 0, this.getWidth(), this.getHeight(), null);
            }
        }
    }

    public Icon getIcon() {
        return icon;
    }

    public void setIcon(Icon icon) {
        this.icon = icon;
        ii = (ImageIcon) icon;
        image = ii.getImage();
        originalHeight = ii.getIconHeight();
        originalWidth = ii.getIconWidth();
    }

    public SizeMode getSizeMode() {
        return sizeMode;
    }

    public void setSizeMode(SizeMode sizeMode) {
        this.sizeMode = sizeMode;
    }

    public enum SizeMode {
        NORMAL,
        STRETCH,
        CENTER,
        ZOOM
    }

    private void aspectRatio() {
        if (ii != null) {
            newHeight = this.getHeight();
            newWidth = (originalWidth * newHeight) / originalHeight;
        }
    }

}

If you want to add an image, choose the JPictureBox, after that go to Properties and find "icon" property and select an image. If you want to change the sizeMode property then choose the JPictureBox, after that go to Properties and find "sizeMode" property, you can choose some values:

• NORMAL value, the image is positioned in the upper-left corner of the JPictureBox.
• STRETCH value causes the image to stretch or shrink to fit the JPictureBox.
• ZOOM value causes the image to be stretched or shrunk to fit the JPictureBox; however, the aspect ratio in the original is maintained.
• CENTER value causes the image to be centered in the client area.

If you want to learn more about this topic, you can check this video.

Also you can see the code on Gitlab or Github.

Eric Baker's comment tipped me off to the core idea that in order for a view to have its size be determined by the content placed within it, then the content placed within it must have an explicit relationship with the containing view in order to drive its height (or width) dynamically. "Add subview" does not create this relationship as you might assume. You have to choose which subview is going to drive the height and/or width of the container... most commonly whatever UI element you have placed in the lower right hand corner of your overall UI. Here's some code and inline comments to illustrate the point.

Note, this may be of particular value to those working with scroll views since it's common to design around a single content view that determines its size (and communicates this to the scroll view) dynamically based on whatever you put in it. Good luck, hope this helps somebody out there.

Not sure about solutions but a temporary workaround is to ask eslint to ignore it by adding the following on top of the problem line.

// eslint-disable-next-line @typescript-eslint/no-unused-expressions

-- Access: 
SELECT CHR(13) & CHR(10) 

-- SQL Server: 
SELECT CHAR(13) + CHAR(10)

Based on Agus's function, but I prefer return just the match values:

var bob = "> bob <";
function matchAll(str, regex) {
    var res = [];
    var m;
    if (regex.global) {
        while (m = regex.exec(str)) {
            res.push(m[1]);
        }
    } else {
        if (m = regex.exec(str)) {
            res.push(m[1]);
        }
    }
    return res;
}
var Amatch = matchAll(bob, /(&.*?;)/g);
console.log(Amatch);  // yeilds: [>, <]

https://www.digitalocean.com/community/tutorials/an-introduction-to-oauth-2

Very brief summary:

OAuth defines four roles:

1. Resource Owner
2. Client
3. Resource Server
4. Authorization Server

You (Resource Owner) have a mobile phone. You have several different email accounts, but you want all your email accounts in one app, so you don't need to keep switching. So your GMail (Client) asks for access (via Yahoo's Authorization Server) to your Yahoo emails (Resource Server) so you can read both emails on your GMail application.

The reason OAuth exists is because it is unsecure for GMail to store your Yahoo username and password.

Here's a swift extension where you can pass any amount of arbitrary colors. It will remove any previous gradients before inserting one and it will return the newly inserted gradient layer for further manipulation if needed:

    extension UIView {

    /**
     Given an Array of CGColor, it will:
        - Remove all sublayers of type CAGradientLayer.
        - Create and insert a new CAGradientLayer.

     - Parameters: 
        - colors: An Array of CGColor with the colors for the gradient fill

     - Returns: The newly created gradient CAGradientLayer
     */
    func layerGradient(colors c:[CGColor])->CAGradientLayer {
        self.layer.sublayers = self.layer.sublayers?.filter(){!($0 is CAGradientLayer)}
        let layer : CAGradientLayer = CAGradientLayer()
        layer.frame.size = self.frame.size
        layer.frame.origin = CGPointZero
        layer.colors = c
        self.layer.insertSublayer(layer, atIndex: 0)
        return layer
    }
}

Solution for ipython 6.2.1 using python 3.5.2 (Tested on Ubuntu 16.04 and Windows 10):

Ipython doesn’t respect %env PYTHONDONTWRITEBYTECODE =1 if set in the ipython interpretor or during startup in ~/.ipython/profile-default/startup/00-startup.ipy. Instead using the following in your ~.ipython/profile-default/startup/00-startup.py

import sys
sys.dont_write_bytecode=True

My definitive solution on Eclipse Luna and m2eclipse: Custom Classloader (download and add to your project, 5 classes only) :http://git.eclipse.org/c/jdt/eclipse.jdt.ui.git/plain/org.eclipse.jdt.ui/jar%20in%20jar%20loader/org/eclipse/jdt/internal/jarinjarloader/; this classloader is very best of one-jar classloader and very fast;

<project.mainClass>org.eclipse.jdt.internal.jarinjarloader.JarRsrcLoader</project.mainClass> <project.realMainClass>my.Class</project.realMainClass>

Edit in JIJConstants "Rsrc-Class-Path" to "Class-Path"
mvn clean dependency:copy-dependencies package
is created a jar with dependencies in lib folder with a thin classloader

There are several issues here.

1. You can't assign DataContext as DataContext="{Binding Employee}" because it's a complex object which can't be assigned as string. So you have to use <Window.DataContext></Window.DataContext> syntax.
2. You assign the class that represents the data context object to the view, not an individual property so {Binding Employee} is invalid here, you just have to specify an object.
3. Now when you assign data context using valid syntax like below

   <Window.DataContext>
      <local:Employee/>
   </Window.DataContext>

know that you are creating a new instance of the Employee class and assigning it as the data context object. You may well have nothing in default constructor so nothing will show up. But then how do you manage it in code behind file? You have typecast the DataContext.

    private void my_button_Click(object sender, RoutedEventArgs e)
    {
        Employee e = (Employee) DataContext;
    }

4. A second way is to assign the data context in the code behind file itself. The advantage then is your code behind file already knows it and can work with it.

   public partial class MainWindow : Window
   {
      Employee employee = new Employee();
   
      public MainWindow()
      {
          InitializeComponent();
   
          DataContext = employee;
      }
   }
   

With ctypes, you can achieve the same thing with

>>> import ctypes
>>> a = (1,2,3)
>>> ctypes.addressof(a)
3077760748L

Documentation:

addressof(C instance) -> integer
Return the address of the C instance internal buffer

Note that in CPython, currently id(a) == ctypes.addressof(a), but ctypes.addressof should return the real address for each Python implementation, if

• ctypes is supported
• memory pointers are a valid notion.

Edit: added information about interpreter-independence of ctypes

A more general approach:

if ( ($("body").hasClass("homepage") || $("body").hasClass("contact")) && (theLanguage == 'en-gb') )   {

       // Do something

}

In Chrome it's possible to hide this automatic header/footer using

@page { margin: 0; }

Since the contents will extend to page's limits, the page printing header/footer will be absent. You should, of course, in this case, set some margins/paddings in your body element so that the content won't extend all the way to the page's edge. Since common printers just can't get no-margins printing and it's probably not what you want, you should use something like this:

@media print {
  @page { margin: 0; }
  body { margin: 1.6cm; }
}

As Martin pointed out in a comment, if the page have a long element that scrolls past one page (like a big table), the margin is ignored and the printed version will look weird.

At the time original of this answer (May 2013), it only worked on Chrome, not sure about it now, never needed to try again. If you need support for a browser that can't hable, you can create a PDF on the fly and print that (you can create a self-printing PDF embedding JavaScript on it), but that's a huge hassle.

Instead of hiding each element, you can hide the whole axis:

frame1.axes.get_xaxis().set_visible(False)
frame1.axes.get_yaxis().set_visible(False)

Or, you can set the ticks to an empty list:

frame1.axes.get_xaxis().set_ticks([])
frame1.axes.get_yaxis().set_ticks([])

In this second option, you can still use plt.xlabel() and plt.ylabel() to add labels to the axes.

.h files will nothing to do with compiling ... you only care about cpp files... so type g++ filename1.cpp filename2.cpp main.cpp -o myprogram

means you are compiling each cpp files and then linked them together into myprgram.

then run your program ./myprogram

I'm not sure, what you mean as the 'mobile width'. But in each case, the CSS @media can be used for hiding elements in the screen width basis. See some example:

<div id="my-content"></div>

...and:

@media screen and (min-width: 0px) and (max-width: 400px) {
  #my-content { display: block; }  /* show it on small screens */
}

@media screen and (min-width: 401px) and (max-width: 1024px) {
  #my-content { display: none; }   /* hide it elsewhere */
}

Some truly mobile detection is kind of hard programming and rather difficult. Eventually see the: http://detectmobilebrowsers.com/ or other similar sources.

If double quotes do not solve the issue then try e.g.

dir /X ~1 c:\

to get a list of alternative file or directory names. Example output:

11/09/2014 12:54 AM             8,065  DEFAUL~1.XML Default Desktop Policy.xml
06/12/2014  03:49 PM    <DIR>          PROGRA~1     Program Files 
10/12/2014  12:46 AM    <DIR>          PROGRA~2     Program Files (x86)

Now use the short 8 character file or folder name in the 5th column, e.g. PROGRA~1 or DEFAUL~1.XML, in your commands. For instance:

set JAVA_HOME=c:\PROGRA~1\Java\jdk1.6.0_45 

I tried @JsonDetect and

@JsonIgnoreProperties(value = { "handler", "hibernateLazyInitializer" })

Neither of them worked for me. Using a third-party module seemed like a lot of work to me. So I just tried making a get call on any property of the lazy object before passing to jackson for serlization. The working code snippet looked something like this :

@RequestMapping(value = "/authenticate", produces = "application/json; charset=utf-8")
    @ResponseBody
    @Transactional
    public Account authenticate(Principal principal) {
        UsernamePasswordAuthenticationToken usernamePasswordAuthenticationToken = (UsernamePasswordAuthenticationToken) principal;
        LoggedInUserDetails loggedInUserDetails = (LoggedInUserDetails) usernamePasswordAuthenticationToken.getPrincipal();
        User user = userRepository.findOne(loggedInUserDetails.getUserId());
        Account account = user.getAccount();
        account.getFullName();      //Since, account is lazy giving it directly to jackson for serlization didn't worked & hence, this quick-fix.
        return account;
    }

I think this does what you are asking for:

webdeveloper.com - decimal to fraction

Width/height gets you a decimal, converted to a fraction with ":" in place of '/' gives you a "ratio".

PDANet driver was the only solution for me to successfully connect to Google Galaxy Nexus 4.2.1 on Windows 7 x64 which was rejecting/ignoring official USB drivers from the latest 4.2 ADK (revision 7) - http://junefabrics.com/android/index.php

Java has nothing of that sort. Why not just do the following?

public static boolean isBetween(int x, int lower, int upper) {
  return lower <= x && x <= upper;
}

if (isBetween(num, 1, 5)) {
  System.out.println("testing case 1 to 5");
} else if (isBetween(num, 6, 10)) {
  System.out.println("testing case 6 to 10");
}

In my opinion the top answers are not readable/maintainable, and the other answers do not properly bind context. Here's a readable solution using ES6 syntax to solve both these problems.

const orginial = someObject.foo;
someObject.foo = function() {
  if (condition) orginial.bind(this)(...arguments);
};

If you are using the HttpURLConnection, call setConnectTimeout() as described here:

URL url = new URL(myurl);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setConnectTimeout(CONNECT_TIMEOUT);

Here const means that at that function any variable's value can not change

class Test{
private:
    int a;
public:
    void test()const{
        a = 10;
    }
};

And like this example, if you try to change the value of a variable in the test function you will get an error.

The latest SDKs (beginning with 2.2, I believe), include TV-Out functionality. With a special cable connected to the iPhone dock connector, a program can send RCA signals representing its current screen contents through the iPhone->RCA cable. If you have a TV Tuner for your computer (i.e. I have an EyeTV Hybrid) with RCA inputs, you can display the screen contents of your iPhone directly in the TV viewer.

For anyone using Django 1.7+, it seems that simply import the settings module is not enough.

After some digging, I found this Stack Overflow answer: https://stackoverflow.com/a/23241093

You now need to:

import os, django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "myapp.settings")
django.setup()
# now your code can go here...

Without doing the above, I was getting a django.core.exceptions.AppRegistryNoReady error.

My script file is in the same directory as my django project (ie. in the same folder as manage.py)

import csv
cols = [' V1', ' I1'] # define your columns here, check the spaces!
data = [[] for col in cols] # this creates a list of **different** lists, not a list of pointers to the same list like you did in [[]]*len(positions) 
with open('data.csv', 'r') as f:
    for rec in csv.DictReader(f):
        for l, col in zip(data, cols):
            l.append(float(rec[col]))
print data

# [[3.0, 3.0], [0.01, 0.01]]

You don't have to use it using src attribute

Wrong way (The image won't fit the button)

android:src="@drawable/myimage"

Right way is to use background atttribute

<ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:background="@drawable/skin" />

where skin is an xml

skin.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- <item android:drawable="@drawable/button_disabled" android:state_enabled="false"/> -->
    <item android:drawable="@drawable/button_pressed" android:state_pressed="true"/>
    <!-- <item android:drawable="@drawable/button_focused" android:state_focused="true"/> -->
    <item android:drawable="@drawable/button_normal"/>

</selector>

using button_pressed.png and button_normal.png

This will also help you in creating your skinned button with 4 states of pressed , normal , disabled and focussed. Make sure to keep same sizes of all pngs

You can learn more about AUROC in this blog post by Miron Kursa:

https://mbq.me/blog/augh-roc/

He provides a fast function for AUROC:

# By Miron Kursa https://mbq.me
auroc <- function(score, bool) {
  n1 <- sum(!bool)
  n2 <- sum(bool)
  U  <- sum(rank(score)[!bool]) - n1 * (n1 + 1) / 2
  return(1 - U / n1 / n2)
}

Let's test it:

set.seed(42)
score <- rnorm(1e3)
bool  <- sample(c(TRUE, FALSE), 1e3, replace = TRUE)

pROC::auc(bool, score)
mltools::auc_roc(score, bool)
ROCR::performance(ROCR::prediction(score, bool), "auc")@y.values[[1]]
auroc(score, bool)

0.51371668847094
0.51371668847094
0.51371668847094
0.51371668847094

auroc() is 100 times faster than pROC::auc() and computeAUC().

auroc() is 10 times faster than mltools::auc_roc() and ROCR::performance().

Check out this question / answer. It's more concise than @Geoff's, and also uses the builtin fputcsv function.

$result = $db_con->query('SELECT * FROM `some_table`');
if (!$result) die('Couldn\'t fetch records');
$num_fields = mysql_num_fields($result);
$headers = array();
for ($i = 0; $i < $num_fields; $i++) {
    $headers[] = mysql_field_name($result , $i);
}
$fp = fopen('php://output', 'w');
if ($fp && $result) {
    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename="export.csv"');
    header('Pragma: no-cache');
    header('Expires: 0');
    fputcsv($fp, $headers);
    while ($row = $result->fetch_array(MYSQLI_NUM)) {
        fputcsv($fp, array_values($row));
    }
    die;
}

This needs to be done on the server-side, where the cookie was issued.

I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.

public abstract class ExternalScript extends Script {

    private String source;

    public void setSource(String file) {
        source = file;
    }

    public String getSource() {
        return source;
    }
}

Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:

• If source was protected (so accessible by subclasses) then code gets messy: who's changing the variables? When it's an object it then becomes hard when you need to refactor, whereas a method tends to make this step easier.
• If your getter/setter methods aren't getting and setting, then describe them as something else.

Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.

Because thats coding convention. See here for more.

Thank Mathias Lin, tested and it works!

In addition, sample implementation of Mathias's method in activity can be as follows.

public class DirectionMapActivity extends MapActivity {

In my case we added the @Profile annotation newly in order to ignore the TestApplication class in production mode and the Application class in test mode.

Unfortunately, we forgot to add the following line into the application.properties files:

spring.profiles.active=test
or
spring.profiles.active=production

Without these config no profile was loaded which caused the not-so-much saying Spring Error.

Maybe is late now but following Spacedman, did you try duplicate="strip" or any other option?

x=runif(1000)
y=runif(1000)
z=rnorm(1000)
s=interp(x,y,z,duplicate="strip")
surface3d(s$x,s$y,s$z,color="blue")
points3d(s)

Right click the project and give maven build,maven clean,maven generate resource and maven install.The jar file will automatically generate.

The <ul> element has browser inherent padding & margin by default. In your case, Use

#footer ul {
    margin: 0; /* To remove default bottom margin */ 
    padding: 0; /* To remove default left padding */
}

or a CSS browser reset ( https://cssreset.com/ ) to deal with this.

Make sure JAVA_HOME is set and the path in environment variables. The PATH should be able to find the keytools.exe

Open “Windows search” and search for "Environment Variables"

Under “System variables” click the “New…” button and enter JAVA_HOME as “Variable name” and the path to your Java JDK directory under “Variable value” it should be similar to this C:\Program Files\Java\jre1.8.0_231

The reason why there is no ConcurrentList is because it fundamentally cannot be written. The reason why is that several important operations in IList rely on indices, and that just plain won't work. For example:

int catIndex = list.IndexOf("cat");
list.Insert(catIndex, "dog");

The effect that the author is going after is to insert "dog" before "cat", but in a multithreaded environment, anything can happen to the list between those two lines of code. For example, another thread might do list.RemoveAt(0), shifting the entire list to the left, but crucially, catIndex will not change. The impact here is that the Insert operation will actually put the "dog" after the cat, not before it.

The several implementations that you see offered as "answers" to this question are well-meaning, but as the above shows, they don't offer reliable results. If you really want list-like semantics in a multithreaded environment, you can't get there by putting locks inside the list implementation methods. You have to ensure that any index you use lives entirely inside the context of the lock. The upshot is that you can use a List in a multithreaded environment with the right locking, but the list itself cannot be made to exist in that world.

If you think you need a concurrent list, there are really just two possibilities:

1. What you really need is a ConcurrentBag
2. You need to create your own collection, perhaps implemented with a List and your own concurrency control.

If you have a ConcurrentBag and are in a position where you need to pass it as an IList, then you have a problem, because the method you're calling has specified that they might try to do something like I did above with the cat & dog. In most worlds, what that means is that the method you're calling is simply not built to work in a multi-threaded environment. That means you either refactor it so that it is or, if you can't, you're going to have to handle it very carefully. You you'll almost certainly be required to create your own collection with its own locks, and call the offending method within a lock.

Here is how I solved the "slow symbol loading" problem in Visual Studio 2012:

• Go to Tools -> Options -> Debugging -> General

• CHECK the checkmark next to "Enable Just My Code".

• Go to Tools -> Options -> Debugging -> Symbols

• Click on the "..." button and create/select a new folder somewhere on your local computer to store cached symbols. I named mine "Symbol caching" and put it in Documents -> Visual Studio 2012.

• Click on "Load all symbols" and wait for the symbols to be downloaded from Microsoft's servers, which may take a while. Note that Load all symbols button is only available while debugging.

• UNCHECK the checkmark next to "Microsoft Symbol Servers" to prevent Visual Studio from remotely querying the Microsoft servers.

• Click "OK".

From now on, symbol loading should be much faster.

Note that if you make any changes/downloads to Microsoft assemblies, you may need to go back into the Symbols dialog box and "Load all symbols" again.

MS-Access doesn't support ROW_NUMBER(). Use TOP 1:

SELECT TOP 1 *
FROM [MyTable]
ORDER BY [MyIdentityCOlumn]

If you need the 15th row - MS-Access has no simple, built-in, way to do this. You can simulate the rownumber by using reverse nested ordering to get this:

SELECT TOP 1 *
FROM (
  SELECT TOP 15 *
  FROM [MyTable]
  ORDER BY [MyIdentityColumn] ) t
ORDER BY [MyIdentityColumn] DESC

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

Stack corruptions ususally caused by buffer overflows. You can defend against them by programming defensively.

Whenever you access an array, put an assert before it to ensure the access is not out of bounds. For example:

assert(i + 1 < N);
assert(i < N);
a[i + 1] = a[i];

This makes you think about array bounds and also makes you think about adding tests to trigger them if possible. If some of these asserts can fail during normal use turn them into a regular if.

There is no such syntax in SQL Server, though CREATE TABLE AS ... SELECT does exist in PDW. In SQL Server you can use this query to create an empty table:

SELECT * INTO schema.newtable FROM schema.oldtable WHERE 1 = 0;

(If you want to make a copy of the table including all of the data, then leave out the WHERE clause.)

Note that this creates the same column structure (including an IDENTITY column if one exists) but it does not copy any indexes, constraints, triggers, etc.

Googled "Permission denied (publickey). fatal: The remote end hung up unexpectedly", first result an exact SO dupe:

I found this helpful

$('select[name=users] option:selected').text()

When accessing the selector using the this keyword.

$(this).find('option:selected').text()

I realize this thread is old, but it's worth mentioning an advantage of storing as a numeric type for formatting purposes, specifically in .NET framework.

IE

.DefaultCellStyle.Format = "(###)###-####" // Will not work on a string

Your elements need to have a position attribute. (e.g. absolute, relative, fixed) or z-index won't work.

I think you can change your query and try it like :

$res=User::where('id',$id)->delete();

  val jobName = "WordCount";
  //overwrite the output directory in spark  set("spark.hadoop.validateOutputSpecs", "false")
  val conf = new 
  SparkConf().setAppName(jobName).set("spark.hadoop.validateOutputSpecs", "false");
  val sc = new SparkContext(conf)

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

You are getting the WebView before setting the Content view so the wv is probably null.

public class ViewWeb extends Activity {  
        @Override  
        public void onCreate(Bundle savedInstanceState) {  
            super.onCreate(savedInstanceState);
            setContentView(R.layout.webview);  
            WebView wv;  
            wv = (WebView) findViewById(R.id.webView1);  
            wv.loadUrl("file:///android_asset/aboutcertified.html");   // now it will not fail here
        }  
    }

There are two ways to tackle this based on what you want:

Solution 1: Remove purple commits, preserving history (incase you want to roll back)

git revert -m 1 <SHA of merge>

-m 1 specifies which parent line to choose

Purple commits will still be there in history but since you have reverted, you will not see code from those commits.

Solution 2: Completely remove purple commits (disruptive change if repo is shared)

git rebase -i <SHA before branching out>

and delete (remove lines) corresponding to purple commits.

This would be less tricky if commits were not made after merge. Additional commits increase the chance of conflicts during revert/rebase.

Use RETURN QUERY:

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt   text   -- also visible as OUT parameter inside function
               , cnt   bigint
               , ratio bigint) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt
        , count(*) AS cnt                 -- column alias only visible inside
        , (count(*) * 100) / _max_tokens  -- I added brackets
   FROM  (
      SELECT t.txt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      LIMIT  _max_tokens
      ) t
   GROUP  BY t.txt
   ORDER  BY cnt DESC;                    -- potential ambiguity 
END
$func$  LANGUAGE plpgsql;

Call:

SELECT * FROM word_frequency(123);

Explanation:

• It is much more practical to explicitly define the return type than simply declaring it as record. This way you don't have to provide a column definition list with every function call. RETURNS TABLE is one way to do that. There are others. Data types of OUT parameters have to match exactly what is returned by the query.

• Choose names for OUT parameters carefully. They are visible in the function body almost anywhere. Table-qualify columns of the same name to avoid conflicts or unexpected results. I did that for all columns in my example.

  But note the potential naming conflict between the OUT parameter cnt and the column alias of the same name. In this particular case (RETURN QUERY SELECT ...) Postgres uses the column alias over the OUT parameter either way. This can be ambiguous in other contexts, though. There are various ways to avoid any confusion:

  1. Use the ordinal position of the item in the SELECT list: ORDER BY 2 DESC. Example:
     • Select first row in each GROUP BY group?
  2. Repeat the expression ORDER BY count(*).
  3. (Not applicable here.) Set the configuration parameter plpgsql.variable_conflict or use the special command #variable_conflict error | use_variable | use_column in the function. See:
     • Naming conflict between function parameter and result of JOIN with USING clause

• Don't use "text" or "count" as column names. Both are legal to use in Postgres, but "count" is a reserved word in standard SQL and a basic function name and "text" is a basic data type. Can lead to confusing errors. I use txt and cnt in my examples.

• Added a missing ; and corrected a syntax error in the header. (_max_tokens int), not (int maxTokens) - type after name.

• While working with integer division, it's better to multiply first and divide later, to minimize the rounding error. Even better: work with numeric (or a floating point type). See below.

Alternative

This is what I think your query should actually look like (calculating a relative share per token):

CREATE OR REPLACE FUNCTION word_frequency(_max_tokens int)
  RETURNS TABLE (txt            text
               , abs_cnt        bigint
               , relative_share numeric) AS
$func$
BEGIN
   RETURN QUERY
   SELECT t.txt, t.cnt
        , round((t.cnt * 100) / (sum(t.cnt) OVER ()), 2)  -- AS relative_share
   FROM  (
      SELECT t.txt, count(*) AS cnt
      FROM   token t
      WHERE  t.chartype = 'ALPHABETIC'
      GROUP  BY t.txt
      ORDER  BY cnt DESC
      LIMIT  _max_tokens
      ) t
   ORDER  BY t.cnt DESC;
END
$func$  LANGUAGE plpgsql;

The expression sum(t.cnt) OVER () is a window function. You could use a CTE instead of the subquery - pretty, but a subquery is typically cheaper in simple cases like this one.

A final explicit RETURN statement is not required (but allowed) when working with OUT parameters or RETURNS TABLE (which makes implicit use of OUT parameters).

round() with two parameters only works for numeric types. count() in the subquery produces a bigint result and a sum() over this bigint produces a numeric result, thus we deal with a numeric number automatically and everything just falls into place.

For single select dom elements, to get the currently selected value:

$('#dropDownId').val();

To get the currently selected text:

$('#dropDownId :selected').text();

As mentioned in other answers, you can do a setEnabled(false) but since you are asking how to set it via XML, here is how to do it.

Add the following attribute to your EditText:

android:enabled="false"

I was getting this error even if I did all the solutions mentioned above.

 by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfig ...

At some point when i look up the POM there was this dependency in it

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>

And the Pojo class had the following imports

import javax.persistence.Entity; import javax.persistence.GeneratedValue; import javax.persistence.Id;

Which clearly shows the application was expecting a datasource.

What I did was I removed the JPA dependency from pom and replaced the imports for the pojo with the following once

import org.springframework.data.annotation.Id; import org.springframework.data.mongodb.core.mapping.Document;

Finally I got SUCCESSFUL build. Check it out you might have run into the same problem

According to the documentation, you can also set global environment variables if you later want to use the value of the variable in other parts of your script. In your case, it would be setting it in the root pipeline:

pipeline {
  ...
  environment {
    FILENAME = readFile ...
  }
  ...
}

You can use JavaScript to disable the context menu (right-click), but it's easily overwrittable. For example, in Firefox, go to Options -> Content and next to the "Enable JavaScript" check box, click Advanced. Uncheck the "Disable or replace context menus" option. Now you can right-click all you want.

A simple CTRL + U will view the source. That can never be disabled.

Saving Indefinitely

You can use the git-credential-store via

git config credential.helper store

which stores your password unencrypted in the file system:

Using this helper will store your passwords unencrypted on disk, protected only by filesystem permissions. If this is not an acceptable security tradeoff, try git-credential-cache, or find a helper that integrates with secure storage provided by your operating system.

With a Timeout

Use the git-credential-cache which by default stores the password for 15 minutes.

git config credential.helper cache

to set a different timeout, use --timeout (here 5 minutes)

git config credential.helper 'cache --timeout=300'

Secure Saving Indefinitely (OS X and Windows)

• If you’re using a Mac, Git comes with an “osxkeychain” mode, which caches credentials in the secure keychain that’s attached to your system account. This method stores the credentials on disk, and they never expire, but they’re encrypted with the same system that stores HTTPS certificates and Safari auto-fills. Running the following on the command line will enable this feature: git config --global credential.helper osxkeychain. You'll need to store the credentials in the Keychain using the Keychain app as well.
• If you’re using Windows, you can install a helper called “Git Credential Manager for Windows.” This is similar to the “osxkeychain” helper described above, but uses the Windows Credential Store to control sensitive information. It can be found at https://github.com/Microsoft/Git-Credential-Manager-for-Windows. [emphases mine]

It doesn't - at least during the compilation phase.

The translation of a c++ program from source code to machine code is performed in three phases:

1. Preprocessing - The Preprocessor parses all source code for lines beginning with # and executes the directives. In your case, the contents of your file class.h is inserted in place of the line #include "class.h. Since you might be includein your header file in several places, the #ifndef clauses avoid duplicate declaration-errors, since the preprocessor directive is undefined only the first time the header file is included.
2. Compilation - The Compiler does now translate all preprocessed source code files to binary object files.
3. Linking - The Linker links (hence the name) together the object files. A reference to your class or one of its methods (which should be declared in class.h and defined in class.cpp) is resolved to the respective offset in one of the object files. I write 'one of your object files' since your class does not need to be defined in a file named class.cpp, it might be in a library which is linked to your project.

In summary, the declarations can be shared through a header file, while the mapping of declarations to definitions is done by the linker.

Probably you did not fetch the remote changes before the rebase or someone pushed new changes (while you were rebasing and trying to push). Try these steps:

#fetching remote 'feature/my_feature_branch' branch to the 'tmp' local branch 
git fetch origin feature/my_feature_branch:tmp

#rebasing on local 'tmp' branch
git rebase tmp

#pushing local changes to the remote
git push origin HEAD:feature/my_feature_branch

#removing temporary created 'tmp' branch
git branch -D tmp

You can also use setShowSoftInputOnFocus(boolean) directly on API 21+ or through reflection on API 14+:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    editText.setShowSoftInputOnFocus(false);
} else {
    try {
        final Method method = EditText.class.getMethod(
                "setShowSoftInputOnFocus"
                , new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(editText, false);
    } catch (Exception e) {
        // ignore

The JavaScript section of the Wikipedia entry, List of Unit Testing Frameworks, provides a list of available choices. It indicates whether they work client-side, server-side, or both.

You might find the yes command useful.

See man yes

Convenient if you repeat yourself a lot:

String.prototype.repeat = String.prototype.repeat || function(n){_x000D_
  n= n || 1;_x000D_
  return Array(n+1).join(this);_x000D_
}_x000D_
_x000D_
alert(  'Are we there yet?\nNo.\n'.repeat(10)  )

All Kafka brokers must be assigned a broker.id. On startup a broker will create an ephemeral node in Zookeeper with a path of /broker/ids/$id. As the node is ephemeral it will be removed as soon as the broker disconnects, e.g. by shutting down.

You can view the list of the ephemeral broker nodes like so:

echo dump | nc localhost 2181 | grep brokers

The ZooKeeper client interface exposes a number of commands; dump lists all the sessions and ephemeral nodes for the cluster.

Note, the above assumes:

• You're running ZooKeeper on the default port (2181) on localhost, and that localhost is the leader for the cluster
• Your zookeeper.connect Kafka config doesn't specify a chroot env for your Kafka cluster i.e. it's just host:port and not host:port/path

This is a charming answer. Work well on any currency which is selected for store.

            [yourTableView beginUpdates];

    Dim rRng As Range

    Set rRng = Sheet1.Range("A1:A6")

    Next rCell

End Sub

The ideal way is not to use ioutil.ReadAll, but rather use a decoder on the reader directly. Here's a nice function that gets a url and decodes its response onto a target structure.

var myClient = &http.Client{Timeout: 10 * time.Second}

func getJson(url string, target interface{}) error {
    r, err := myClient.Get(url)
    if err != nil {
        return err
    }
    defer r.Body.Close()

    return json.NewDecoder(r.Body).Decode(target)
}

Example use:

type Foo struct {
    Bar string
}

func main() {
    foo1 := new(Foo) // or &Foo{}
    getJson("http://example.com", foo1)
    println(foo1.Bar)

    // alternately:

    foo2 := Foo{}
    getJson("http://example.com", &foo2)
    println(foo2.Bar)
}

You should not be using the default *http.Client structure in production as this answer originally demonstrated! (Which is what http.Get/etc call to). The reason is that the default client has no timeout set; if the remote server is unresponsive, you're going to have a bad day.

num = raw_input ("Type Number : ")
search = open("file.txt","r")
for line in search.readlines():
    for digit in num:
        # Check if any of the digits provided by the user are in the line.
        if digit in line:
            print line
            continue

You can request a path in this format:

/package/path/to/the/resource.ext

Even the bytes for creating the classes in memory are found this way:

my.Class -> /my/Class.class

and getResource will give you a URL which can be used to retrieve an InputStream.

But... I'd recommend using directly getClass().getResourceAsStream(...) with the same argument, because it returns directly the InputStream and don't have to worry about creating a (probably complex) URL object that has to know how to create the InputStream.

In short: try using getResourceAsStream and some constructor of ImageIcon that uses an InputStream as an argument.

Classloaders

Be careful if your app has many classloaders. If you have a simple standalone application (no servers or complex things) you shouldn't worry. I don't think it's the case provided ImageIcon was capable of finding it.

Edit: classpath

getResource is—as mattb says—for loading resources from the classpath (from your .jar or classpath directory). If you are bundling an app it's nice to have altogether, so you could include the icon file inside the jar of your app and obtain it this way.

SELECT  *
FROM    table
WHERE   some_id = ANY(ARRAY[1, 2])

or ANSI-compatible:

SELECT  *
FROM    table
WHERE   some_id IN (1, 2)

The ANY syntax is preferred because the array as a whole can be passed in a bound variable:

SELECT  *
FROM    table
WHERE   some_id = ANY(?::INT[])

You would need to pass a string representation of the array: {1,2}

That helped me with my code.

When I tried feltering only a type of files and show them on screen by adding a condition that tests on each line.

Like this

elif command == 'ls':
    print("directory of ", ftp.pwd())
    data = []
    ftp.dir(data.append)

    for line in data:
        x = line.split(".")
        formats=["gz", "zip", "rar", "tar", "bz2", "xz"]
        if x[-1] in formats:
            print ("-", line)

I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;

It works and it's cross browser compatible.

Check out the code below, you probably get a better explanation:

Use the target attribute on your anchor tag with the _blank value.

Example:

<a href="http://google.com" target="_blank">Click Me!</a>

this should do:

//Main Class
public class SomeClass {

    //Sub-Class
    public static class AnotherClass {
        public enum MyEnum {
            VALUE_A, VALUE_B
        }    
        public MyEnum myEnum;
    }

    public void someMethod() { 
        AnotherClass.MyEnum enumExample = AnotherClass.MyEnum.VALUE_A; //...

        switch (enumExample) {
            case VALUE_A: { //<-- error on this line
            //..
            break;
            }
        }
    }
}

Hi I have been using this page a lot for constraints and "how to". It took me forever to get to the point of realizing I needed:

myView.translatesAutoresizingMaskIntoConstraints = NO;

to get this example to work. Thank you Userxxx, Rob M. and especially larsacus for the explanation and code here, it has been invaluable.

Here is the code in full to get the examples above to run:

UIView *myView = [[UIView alloc] init];
myView.backgroundColor = [UIColor redColor];
myView.translatesAutoresizingMaskIntoConstraints = NO;  //This part hung me up 
[self.view addSubview:myView];
//needed to make smaller for iPhone 4 dev here, so >=200 instead of 748
[self.view addConstraints:[NSLayoutConstraint
                           constraintsWithVisualFormat:@"V:|-[myView(>=200)]-|"
                           options:NSLayoutFormatDirectionLeadingToTrailing
                           metrics:nil
                           views:NSDictionaryOfVariableBindings(myView)]];

[self.view addConstraints:[NSLayoutConstraint
                           constraintsWithVisualFormat:@"H:[myView(==200)]-|"
                           options:NSLayoutFormatDirectionLeadingToTrailing
                           metrics:nil
                           views:NSDictionaryOfVariableBindings(myView)]];

You don't need to go level up and use .. since all buttons are on the same level:

//button[contains(.,'Arcade Reader')]/preceding-sibling::button[@name='settings']

you can parse string with int.parse('your string value');.

Example:- int num = int.parse('110011'); print(num); // prints 110011 ;

You could store by creating an object that hold a string value number to store in an array list. by example: BigInt objt = new BigInt("999999999999999999999999999999999999999999999999999");

objt is created by the constructor of BigInt class. Inside the class look like.

BigInt{

ArrayList<Integer> myNumber = new ArrayList <Integer>();        

public BigInt(){}

public BigInt(String number){ for(int i; i<number.length; i++){ myNumber.add(number.indexOf(i)); } }

}

For that I have written the following code in the "ActionPeformed(...)" method of the "Start" button

You need that code to be in the actionPerformed(...) of the ActionListener registered with the Start button, not for the Start button itself.

You can add a simple ActionListener like this:

JButton startButton = new JButton("Start");
startButton.addActionListener(new ActionListener() {
     public void actionPerformed(ActionEvent ae) {
        startButton.setEnabled(false);
        stopButton.setEnabled(true);
     }
   }
 );

note that your startButton above will need to be final in the above example if you want to create the anonymous listener in local scope.

Due to security issues (same origin policy), javascript access to local files is restricted if without user interaction.

According to https://developer.mozilla.org/en-US/docs/Same-origin_policy_for_file:_URIs:

A file can read another file only if the parent directory of the originating file is an ancestor directory of the target file.

Imagine a situation when javascript from a website tries to steal your files anywhere in your system without you being aware of. You have to deploy it to a web server. Or try to load it with a script tag. Like this:

<script type="text/javascript" language="javascript" src="jquery-1.8.2.min.js"></script>        
<script type="text/javascript" language="javascript" src="priorities.json"></script> 

<script type="text/javascript">
   $(document).ready(function(e) {
         alert(jsonObject.start.count);
   });
</script>

Your priorities.json file:

var jsonObject = {
"start": {
    "count": "5",
    "title": "start",
    "priorities": [
        {
            "txt": "Work"
        },
        {
            "txt": "Time Sense"
        },
        {
            "txt": "Dicipline"
        },
        {
            "txt": "Confidence"
        },
        {
            "txt": "CrossFunctional"
        }
    ]
}
}

Or declare a callback function on your page and wrap it like jsonp technique:

<script type="text/javascript" language="javascript" src="jquery-1.8.2.min.js">    </script> 
     <script type="text/javascript">
           $(document).ready(function(e) {

           });

           function jsonCallback(jsonObject){
               alert(jsonObject.start.count);
           }
        </script>

 <script type="text/javascript" language="javascript" src="priorities.json"></script> 

Your priorities.json file:

jsonCallback({
    "start": {
        "count": "5",
        "title": "start",
        "priorities": [
            {
                "txt": "Work"
            },
            {
                "txt": "Time Sense"
            },
            {
                "txt": "Dicipline"
            },
            {
                "txt": "Confidence"
            },
            {
                "txt": "CrossFunctional"
            }
        ]
    }
    })

Using script tag is a similar technique to JSONP, but with this approach it's not so flexible. I recommend deploying it on a web server.

With user interaction, javascript is allowed access to files. That's the case of File API. Using file api, javascript can access files selected by the user from <input type="file"/> or dropped from the desktop to the browser.

You can try this methods

window.open(location, '_self').close();

The KeyDown event only triggered at the standard TextBox or MaskedTextBox by "normal" input keys, not ENTER or TAB and so on.

One can get special keys like ENTER by overriding the IsInputKey method:

public class CustomTextBox : System.Windows.Forms.TextBox
{
    protected override bool IsInputKey(Keys keyData)
    {
        if (keyData == Keys.Return)
            return true;
        return base.IsInputKey(keyData);
    }
}

Then one can use the KeyDown event in the following way:

CustomTextBox ctb = new CustomTextBox();
ctb.KeyDown += new KeyEventHandler(tb_KeyDown);

private void tb_KeyDown(object sender, KeyEventArgs e)
{
    if (e.KeyCode == Keys.Enter)
    {
          //Enter key is down

          //Capture the text
          if (sender is TextBox)
          {
              TextBox txb = (TextBox)sender;
              MessageBox.Show(txb.Text);
          }
    }
}

A simple brew update && brew upgrade did the trick for me

For below code, xGen is an anonomous generator expression, yFilt is a filter object. Note that for xGen the additional None parameter is returned rather than throwing StopIteration when the list is exhausted.

arr =((10,0), (11,1), (12,2), (13,2), (14,3))

value = 2
xGen = (x for x in arr if x[1] == value)
yFilt = filter(lambda x: x[1] == value, arr)
print(type(xGen))
print(type(yFilt))

for i in range(1,4):
    print('xGen: pass=',i,' result=',next(xGen,None))
    print('yFilt: pass=',i,' result=',next(yFilt))

Output:

<class 'generator'>
<class 'filter'>
xGen: pass= 1  result= (12, 2)
yFilt: pass= 1  result= (12, 2)
xGen: pass= 2  result= (13, 2)
yFilt: pass= 2  result= (13, 2)
xGen: pass= 3  result= None
Traceback (most recent call last):
  File "test.py", line 12, in <module>
    print('yFilt: pass=',i,' result=',next(yFilt))
StopIteration

The second is pretty standard. You often prefer to return a reference from an assignment operator so that statements like a = b = c; resolve as expected. I can't think of any cases where I would want to return a copy from assignment.

One thing to note is that if you aren't needing a deep copy it's sometimes considered best to use the implicit copy constructor and assignment operator generated by the compiler than roll your own. Really up to you though ...

Edit:

Here's some basic calls:

SimpleCircle x; // default constructor
SimpleCircle y(x); // copy constructor
x = y; // assignment operator

Now say we had the first version of your assignment operator:

SimpleCircle SimpleCircle::operator=(const SimpleCircle & rhs)
{
     if(this == &rhs)
        return *this; // calls copy constructor SimpleCircle(*this)
     itsRadius = rhs.getRadius(); // copy member
     return *this; // calls copy constructor
}

It calls the copy constructor and passes a reference to this in order to construct the copy to be returned. Now in the second example we avoid the copy by just returning a reference to this

SimpleCircle & SimpleCircle::operator=(const SimpleCircle & rhs)
{
    if(this == &rhs)
       return *this; // return reference to this (no copy)
    itsRadius = rhs.getRadius(); // copy member
    return *this; // return reference to this (no copy)
}

Not direct answer but may help ....

The npm also has a cache folder, which can be found by running npm config get cache (%AppData%/npm-cache on Windows).

The npm modules are first downloaded here and then copied to npm global folder (%AppData%/Roaming/npm on Windows) or project specific folder (your-project/node_modules).

So if you want to track npm packages, and some how, the list of all downloaded npm packages (if the npm cache is not cleaned) have a look at this folder. The folder structure is as {cache}/{name}/{version}

This may help also https://docs.npmjs.com/cli/cache

For me none of the solution worked, but If i disconnect the phone from laptop and then run the build, it succeeds and then I connect and run on the phone. I still couldn't figure out the final fix.

This should do the trick

'g' in df.index

The problem is in your pubspec.yaml, here you need to delete the last comma.

uses-material-design: true,

Taken from this answer.

1. Close your packages.config file.
2. Build
3. Warning is gone!

This is the first time I see ignoring a problem actually makes it go away...

Edit in 2020: if you are viewing this warning, consider upgrading to PackageReference if you can

Jerry's answer is great. However, it doesn't handle large responses. A simple change to handle this:

memset(response, 0, sizeof(response));
total = sizeof(response)-1;
received = 0;
do {
    printf("RESPONSE: %s\n", response);
    // HANDLE RESPONSE CHUCK HERE BY, FOR EXAMPLE, SAVING TO A FILE.
    memset(response, 0, sizeof(response));
    bytes = recv(sockfd, response, 1024, 0);
    if (bytes < 0)
        printf("ERROR reading response from socket");
    if (bytes == 0)
        break;
    received+=bytes;
} while (1); 

this reference a javascript object and $(this) used to encapsulate with jQuery.

Example =>

// Getting Name and modify css property of dom object through jQuery
var name = $(this).attr('name');
$(this).css('background-color','white')

// Getting form object and its data and work on..
this = document.getElementsByName("new_photo")[0]
formData = new FormData(this)

// Calling blur method on find input field with help of both as below
$(this).find('input[type=text]')[0].blur()

//Above is equivalent to
this = $(this).find('input[type=text]')[0]
this.blur()

//Find value of a text field with id "index-number"
this = document.getElementById("index-number");
this.value

or 

this = $('#index-number');
$(this).val(); // Equivalent to $('#index-number').val()
$(this).css('color','#000000')

You can do something like this in your click or celldoubleclick event of your grid(if you used one)

if(dgEmp.CurrentRow.Index != -1)
 {
    employ.Id = (Int32)dgEmp.CurrentRow.Cells["Id"].Value;
    //Some other stuff here
 }

Then do something like this in your Delete Button:

using(Context context = new Context())
{
     var entry = context.Entry(employ);
     if(entry.State == EntityState.Detached)
     {
        //Attached it since the record is already being tracked
        context.Employee.Attach(employ);
     }                             
     //Use Remove method to remove it virtually from the memory               
     context.Employee.Remove(employ);
     //Finally, execute SaveChanges method to finalized the delete command 
     //to the actual table
     context.SaveChanges();

     //Some stuff here
}

Alternatively, you can use a LINQ Query instead of using LINQ To Entities Query:

var query = (from emp in db.Employee

employ.Id is used as filtering parameter which was already passed from the CellDoubleClick Event of your DataGridView.

Modified version of divround :-)

def divround(value, step, barrage):
    result, rest = divmod(value, step)
    return result*step if rest < barrage else (result+1)*step

Found a solution that modifies the android.bat to allow you to start and run the android sdk and avd manager on the x64 jdk. So far I've been able to start it updating, but I don't know what other implications running the emulator and compiling against the x64 jdk will have.

good luck.

onerror Event

*Update August 2017: onerror is fired by Chrome and Firefox. onload is fired by Internet Explorer. Edge fires neither onerror nor onload. I wouldnt use this method but it could work in some cases. See also

<link> onerror do not work in IE

*

Definition and Usage The onerror event is triggered if an error occurs while loading an external file (e.g. a document or an image).

Tip: When used on audio/video media, related events that occurs when there is some kind of disturbance to the media loading process, are:

• onabort
• onemptied
• onstalled
• onsuspend

In HTML:

element onerror="myScript">

In JavaScript, using the addEventListener() method:

object.addEventListener("error", myScript);

Note: The addEventListener() method is not supported in Internet Explorer 8 and earlier versions.

Example Execute a JavaScript if an error occurs when loading an image:

img src="image.gif" onerror="myFunction()">

Backtick quotes with a space inside and two spaces to follow. Repeat as needed for more lines:

text1 text1
`(space)`(space)(space)
`(space)`(space)(space)
text2 text2

It looks decent in Markdown source:

text1 text1
` `  
` `  
text2 text2

First of all, you would have to allocate memory:

char * S = new char[R.length() + 1];

then you can use strcpy with S and R.c_str():

std::strcpy(S,R.c_str());

You can also use R.c_str() if the string doesn't get changed or the c string is only used once. However, if S is going to be modified, you should copy the string, as writing to R.c_str() results in undefined behavior.

Note: Instead of strcpy you can also use str::copy.

I believe you can found the answer here Xcode 5 - "No application records were found" when trying to Validate an Archive from @Bamsworld.

As you already mentioned and as per the documentation - App Distribution Guide

Important: You can’t validate your app unless the app record in iTunes Connect is in the “Waiting for Upload” or later state After you add a new app in iTunes connect there will be an amber light along with its status. It will most likely read "Prepare For Upload". To get it to the "Waiting For Upload" state click view details for the app and in the top right there should be a blue button that says "Ready to Upload Binary". Click this and follow the given directions.

The docs describe the attributes available on the request. In most common cases request.data will be empty because it's used as a fallback:

request.data Contains the incoming request data as string in case it came with a mimetype Flask does not handle.

• request.args: the key/value pairs in the URL query string
• request.form: the key/value pairs in the body, from a HTML post form, or JavaScript request that isn't JSON encoded
• request.files: the files in the body, which Flask keeps separate from form. HTML forms must use enctype=multipart/form-data or files will not be uploaded.
• request.values: combined args and form, preferring args if keys overlap
• request.json: parsed JSON data. The request must have the application/json content type, or use request.get_json(force=True) to ignore the content type.

All of these are MultiDict instances (except for json). You can access values using:

• request.form['name']: use indexing if you know the key exists
• request.form.get('name'): use get if the key might not exist
• request.form.getlist('name'): use getlist if the key is sent multiple times and you want a list of values. get only returns the first value.

It is as simple as:

String charIs = string.charAt(index) + "";

Another clever way from that ancient thread:

int age = (
    Int32.Parse(DateTime.Today.ToString("yyyyMMdd")) - 
    Int32.Parse(birthday.ToString("yyyyMMdd"))) / 10000;

You need to loop over each of the elements in the slice and test. Equality for slices is not defined. However, there is a bytes.Equal function if you are comparing values of type []byte.

func testEq(a, b []Type) bool {

    // If one is nil, the other must also be nil.
    if (a == nil) != (b == nil) { 
        return false; 
    }

    if len(a) != len(b) {
        return false
    }

    for i := range a {
        if a[i] != b[i] {
            return false
        }
    }

    return true
}

Here is another good article that you may check out on Domain Driven Design. if your application is anything serious than college assignment. The basic premise is structure everything around your entities and have a strong domain model. Differentiate between services that provide infrastructure related things (like sending email, persisting data) and services that actually do things that are your core business requirments.

Hope that helps.

While none of these answers worked for me, I was able to fix the issue using the following command.

git fetch origin

This did a trick for me.

If you want this sentence from foo.bar import foo2 to be loaded dynamically, you should do this

foo = __import__("foo")
bar = getattr(foo,"bar")
foo2 = getattr(bar,"foo2")

instance = foo2()

In Swift use

mapView.showAnnotations(annotationArray, animated: true)

In Objective c

[mapView showAnnotations:annotationArray animated:YES];

Go to "Run" and execute this:

%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -ir

NOTE: run as administrator.

Parenthesis () are used to enable grouping of regex phrases.

The group(1) contains the string that is between parenthesis (.*) so .* in this case

And group(0) contains whole matched string.

If you would have more groups (read (...) ) it would be put into groups with next indexes (2, 3 and so on).

Additionally to the answer of @tkruse and @Yishai:
I do this way to conditionally skip test methods especially for Parameterized tests, if a test method should only run for some test data records.

public class MyTest {
    // get current test method
    @Rule public TestName testName = new TestName();
    
    @Before
    public void setUp() {
        org.junit.Assume.assumeTrue(new Function<String, Boolean>() {
          @Override
          public Boolean apply(String testMethod) {
            if (testMethod.startsWith("testMyMethod")) {
              return <some condition>;
            }
            return true;
          }
        }.apply(testName.getMethodName()));
        
        ... continue setup ...
    }
}

I added customBinding to the web.config.

<configuration>
  <system.serviceModel>
    <bindings>
      <customBinding>
        <binding name="CustomSoapBinding">
          <security includeTimestamp="false"
                    authenticationMode="UserNameOverTransport"
                    defaultAlgorithmSuite="Basic256"
                    requireDerivedKeys="false"
                    messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10">
          </security>
          <textMessageEncoding messageVersion="Soap11"></textMessageEncoding>
          <httpsTransport maxReceivedMessageSize="2000000000"/>
        </binding>
      </customBinding>
    </bindings>
    <client>
      <endpoint address="https://test.com:443/services/testService"
                binding="customBinding"
                bindingConfiguration="CustomSoapBinding"
                contract="testService.test"
                name="test" />
    </client>
  </system.serviceModel>
  <startup>
    <supportedRuntime version="v4.0"
                      sku=".NETFramework,Version=v4.0"/>
  </startup>
</configuration>

After adding customBinding, I can pass username and password to client service like as follows:

service.ClientCridentials.UserName.UserName = "testUser";
service.ClientCridentials.UserName.Password = "testPass";

In this way you can pass username, password in the header to a SOAP WCF Service.

I was having issues with this as well. I was using the jdbc connection string to connect to the database. The hostname was incorrectly configured in the string. I am using Mac, and the same string was being used on Windows machines without an issue. On my connection string, I had to make sure that I had the full url with the appending "organizationname.com" to the end of the hostname.

Hope this helps.

For Git versions 1.8.0 and higher:

Actually for the accepted answer to work:

git remote add upstream <remote-url>
git fetch upstream
git branch -f --track qa upstream/qa
# OR Git version 1.8.0 and higher:
git branch --set-upstream-to=upstream/qa
# Gitversions lower than 1.8.0
git branch --set-upstream qa upstream/qa

One alternative would be to use a drawable/textview instead of a checkbox and manipulate it accordingly. I have used this method to have my own checked and unchecked images for a task application.
