Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild

In case if you using Intellij https://www.jetbrains.com/datagrip/features/importexport.html

I do this without external libaries:

var yourArray = ['aaa','bbb','ccc'];
var counter = [];

yourArray.forEach(function(name){
    conn.collection(name).drop(function(err) {
        counter.push(true);
        console.log('dropped');
        if(counter.length === yourArray.length){
            console.log('all dropped');
        }
    });                
});

t returns the number of days in the month of a given date (see the docs for date):

$a_date = "2009-11-23";
echo date("Y-m-t", strtotime($a_date));

jQuery.val() and .text() will never return 'undefined' for an empty selection. It always returns an empty string (i.e. ""). .html() will return null if the element doesn't exist though.You need to do:

if(page_name != '')

For other variables that don't come from something like jQuery.val() you would do this though:

if(typeof page_name != 'undefined')

You just have to use the typeof operator.

please, be sure your connected to a ubuntu server, I Had the same problem but I was connected to other distro, check the AMI value in your details instance, it should be something like

AMI: ubuntu/images/ebs/ubuntu-precise-12.04-amd64-server-20130411.1 

hope it helps

I know this is a very old thread, but it is the top google search for this error, and none of the responses mention a common cause of the error.

Which is closing a file you've already closed.

If you're not paying attention and have two different functions close the same file, then the second one will generate this error.

Use unshift, which modifies the existing array by adding the arguments to the beginning:

TheArray.unshift(TheNewObject);

In my case, It was from Stored Producers. I was removed a field from table and forgotten to remove it from my SP.

Technique 1:

 DECLARE @p_date DATETIME
 SET     @p_date = CONVERT( DATETIME, '14 AUG 2008', 106 )

 SELECT  *
 FROM    table1
 WHERE   column_datetime >= @p_date
 AND     column_datetime < DATEADD(d, 1, @p_date)

The advantage of this is that it will use any index on 'column_datetime' if it exists.

If null never indicates an error then just return null.

If null is always an error then throw an exception.

If null is sometimes an exception then code two routines. One routine throws an exception and the other is a boolean test routine that returns the object in an output parameter and the routine returns a false if the object was not found.

It's hard to misuse a Try routine. It's real easy to forget to check for null.

So when null is an error you just write

object o = FindObject();

When the null isn't an error you can code something like

if (TryFindObject(out object o)
  // Do something with o
else
  // o was not found

I think it will work

for (int i = 1; i <= broj_ds; i++ ) 
  { 

     QuantityInIssueUnit_value = dr_art_line_2[i]["Column"];
     QuantityInIssueUnit_uom  = dr_art_line_2[i]["Column"];

  }

Using the base package:

df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))

# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]

# One line
df[df$name %in% c("Tom", "Lynn"), ] 

Output:

  days name
1   88 Lynn
2   11  Tom
6    1  Tom
7  222 Lynn
8    2 Lynn

Using sqldf:

library(sqldf)
# Two alternatives:
sqldf('SELECT *
      FROM df 
      WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
      FROM df 
      WHERE name IN ("Tom", "Lynn")')

If I understand correctly, you want to have one class implement multiple of those interfaces with different input/output parameters? This will not work in Java, because the generics are implemented via erasure.

The problem with the Java generics is that the generics are in fact nothing but compiler magic. At runtime, the classes do not keep any information about the types used for generic stuff (class type parameters, method type parameters, interface type parameters). Therefore, even though you could have overloads of specific methods, you cannot bind those to multiple interface implementations which differ in their generic type parameters only.

In general, I can see why you think that this code has a smell. However, in order to provide you with a better solution, it would be necessary to know a little more about your requirements. Why do you want to use a generic interface in the first place?

Another solution if you want to keep this column as index.

pd.read_csv('filename.csv', index_col='Unnamed: 0')

In my case, I had replaced math library files from a previous Game Engine Graphics course with GLM. The problem was that I didn't add them to the project within Visual Studio's Solution Explorer (even though they were in the project repository).

There is an open issue to only print this warning if there was actually something sanitized: https://github.com/angular/angular/pull/10272

I didn't read in detail when this warning is printed when nothing was sanitized.

You could create a user form:

http://www.excel-vba-easy.com/vba-userform-excel-vba.html

Here's my answer for those that are Googling:

CSS:

.column {
    float: left;
    width: 50%;
}

/* Clear floats after the columns */
.container:after {
    content: "";
    display: table;
    clear: both;
}

Here's the HTML:

<div class="container">
    <div class="column"></div>
    <div class="column"></div>
</div>

Try

.img{
   width:100vw; /* Matches to the Viewport Width */
   height:auto;
   max-width:100% !important;
}

Only works with display block and inline block, this has no effect on flex items as I've just spent ages trying to find out.

Couple issues that I see. fetch_results is a class, not an Id and the each function doesn't look right.

$('.fetch_results:input').each(function() {
      $(this).val('');
});

Just be sure to remember that if you end up with radios or check buttons, you will have to clear the checked attribute, not the value.

Or you can put in the CSS,

<style>
div#img {
  background-image: url(“file.png");
  color:yellow (this part doesn't matter;
  height:100%;
  width:100%;
}
</style>

May I humbly suggest the Rabin-Karp algorithm if the big list is really big. The link even contains almost-usable code in almost-Python.

For anyone using swift 4.2 with Xcode 10:

CommonCrypto module is now provided by the system, so you can directly import it like any other system framework.

import CommonCrypto

In my case I forgot it was packaging conflict jar vs pom. I forgot to write

<packaging>pom</packaging>

In every child pom.xml file

I would always recommend going to the authoritative source when trying to understand the meaning and purpose of HTTP headers.

The "Host" header field in a request provides the host and port
information from the target URI, enabling the origin server to
distinguish among resources while servicing requests for multiple
host names on a single IP address.

https://tools.ietf.org/html/rfc7230#section-5.4

I'm not sure there's a clear-cut definition of "framework". Sometimes a large set of libraries is called a framework, but I think the typical use of the word is closer to the definition aioobe brought.

This very nice article sums up the difference between just a set of libraries and a framework:

A framework can be defined as a set of libraries that say “Don’t call us, we’ll call you.”

How does a framework help you? Because instead of writing something from scratch, you basically just extend a given, working application. You get a lot of productivity this way - sometimes the resulting application can be far more elaborate than you could have done on your own in the same time frame - but you usually trade in a lot of flexibility.

According to the API the constructor which would accept year, month, and so on is deprecated. Instead you should use the Constructor which accepts a long. You could use a Calendar implementation to construct the date you want and access the time-representation as a long, for example with the getTimeInMillis method.

Adding this option for dealing with basic uint8 to byte[] conversion

foo := 255 // 1 - 255
ufoo := uint16(foo) 
far := []byte{0,0}
binary.LittleEndian.PutUint16(far, ufoo)
bar := int(far[0]) // back to int
fmt.Println("foo, far, bar : ",foo,far,bar)

output : foo, far, bar : 255 [255 0] 255

ok in addition to @user3096626 answer i think it will be more helpful if someone provided code example, the following example will show you how to fix image orientation comes from url (remote images):

Solution 1: using javascript (recommended)

1. because load-image library doesn't extract exif tags from url images only (file/blob), we will use both exif-js and load-image javascript libraries, so first add these libraries to your page as the follow:

   <script src="https://cdnjs.cloudflare.com/ajax/libs/exif-js/2.1.0/exif.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-scale.min.js"></script>
   <script src="https://cdnjs.cloudflare.com/ajax/libs/blueimp-load-image/2.12.2/load-image-orientation.min.js"></script>
   

   Note the version 2.2 of exif-js seems has issues so we used 2.1

2. then basically what we will do is

   a - load the image using window.loadImage()

   b - read exif tags using window.EXIF.getData()

   c - convert the image to canvas and fix the image orientation using window.loadImage.scale()

   d - place the canvas into the document

here you go :)

window.loadImage("/your-image.jpg", function (img) {
  if (img.type === "error") {
    console.log("couldn't load image:", img);
  } else {
    window.EXIF.getData(img, function () {
        var orientation = EXIF.getTag(this, "Orientation");
        var canvas = window.loadImage.scale(img, {orientation: orientation || 0, canvas: true});
        document.getElementById("container").appendChild(canvas); 
        // or using jquery $("#container").append(canvas);

    });
  }
});

of course also you can get the image as base64 from the canvas object and place it in the img src attribute, so using jQuery you can do ;)

$("#my-image").attr("src",canvas.toDataURL());

here is the full code on: github: https://github.com/digital-flowers/loadimage-exif-example

Solution 2: using html (browser hack)

there is a very quick and easy hack, most browsers display the image in the right orientation if the image is opened inside a new tab directly without any html (LOL i don't know why), so basically you can display your image using iframe by putting the iframe src attribute as the image url directly:

<iframe src="/my-image.jpg"></iframe>

Solution 3: using css (only firefox & safari on ios)

there is css3 attribute to fix image orientation but the problem it is only working on firefox and safari/ios it is still worth mention because soon it will be available for all browsers (Browser support info from caniuse)

img {
   image-orientation: from-image;
}

With IE 10 I resolved the problem with :

    var file = document.getElementById("file-input");
    file.removeAttribute('value');
    file.parentNode.replaceChild(file.cloneNode(true),file);

where :

<input accept="image/*" onchange="angular.element(this).scope().uploadFile(this)" id="file-input" type="file"/>

In Java 8 you can do this

Files.walk(Paths.get("/path/to/folder"))
     .filter(Files::isRegularFile)
     .forEach(System.out::println);

which will print all files in a folder while excluding all directories. If you need a list, the following will do:

Files.walk(Paths.get("/path/to/folder"))
     .filter(Files::isRegularFile)
     .collect(Collectors.toList())

If you want to return List<File> instead of List<Path> just map it:

List<File> filesInFolder = Files.walk(Paths.get("/path/to/folder"))
                                .filter(Files::isRegularFile)
                                .map(Path::toFile)
                                .collect(Collectors.toList());

You also need to make sure to close the stream! Otherwise you might run into an exception telling you that too many files are open. Read here for more information.

The following signature will do:

List<Email> findByEmailIdInAndPincodeIn(List<String> emails, List<String> pinCodes);

This is derived from @fallino's answer, with some adjustments and simplifications by using the output format option for docker history. Since macOS and Gnu/Linux have different command-line utilities, a different version is necessary for Mac. If you only need one or the other, you can just use those lines.

don't know windows 8 but you can probably set the default prog for a specific extension, for example on windows 7 you do right click => open with, then you select the prog you want and select 'use this prog as default', or you can remove your old version of python from your path and add the one of the anaconda

It can be done like this as well:

target.write(line1 + "\n" + line2 + "\n" + line3 + "\n")

From iOS 6 and later UITextAlignment is deprecated. use NSTextAlignment

About the recalculation:

You can keep your set of random values from changing every time you make an adjustment, by adjusting the automatic recalculation, to: manual recalculate. (Re)calculations are then only done when you press F9. Or shift F9.

See this link (though for older excel version than the current 2013) for some info about it: https://support.office.com/en-us/article/Change-formula-recalculation-iteration-or-precision-73fc7dac-91cf-4d36-86e8-67124f6bcce4.

Mutexes have ownership, unlike semaphores. Although any thread, within the scope of a mutex, can get an unlocked mutex and lock access to the same critical section of code,only the thread that locked a mutex should unlock it.

It is reasonable to make constructor private if there are other methods that can produce instances. Obvious examples are patterns Singleton (every call return the same instance) and Factory (every call usually create new instance).

You actually can't manually "free" memory in C, in the sense that the memory is released from the process back to the OS ... when you call malloc(), the underlying libc-runtime will request from the OS a memory region. On Linux, this may be done though a relatively "heavy" call like mmap(). Once this memory region is mapped to your program, there is a linked-list setup called the "free store" that manages this allocated memory region. When you call malloc(), it quickly looks though the free-store for a free block of memory at the size requested. It then adjusts the linked list to reflect that there has been a chunk of memory taken out of the originally allocated memory pool. When you call free() the memory block is placed back in the free-store as a linked-list node that indicates its an available chunk of memory.

If you request more memory than what is located in the free-store, the libc-runtime will again request more memory from the OS up to the limit of the OS's ability to allocate memory for running processes. When you free memory though, it's not returned back to the OS ... it's typically recycled back into the free-store where it can be used again by another call to malloc(). Thus, if you make a lot of calls to malloc() and free() with varying memory size requests, it could, in theory, cause a condition called "memory fragmentation", where there is enough space in the free-store to allocate your requested memory block, but not enough contiguous space for the size of the block you've requested. Thus the call to malloc() fails, and you're effectively "out-of-memory" even though there may be plenty of memory available as a total amount of bytes in the free-store.

According to the Box-cox transformation formula in the paper Box,George E. P.; Cox,D.R.(1964). "An analysis of transformations", I think mlegge's post might need to be slightly edited.The transformed y should be (y^(lambda)-1)/lambda instead of y^(lambda). (Actually, y^(lambda) is called Tukey transformation, which is another distinct transformation formula.)
So, the code should be:

(trans <- bc$x[which.max(bc$y)])
[1] 0.4242424
# re-run with transformation
mnew <- lm(((y^trans-1)/trans) ~ x) # Instead of mnew <- lm(y^trans ~ x)

New Way

Starting with Go 1.16, use os.ReadFile to load the file to memory, use os.WriteFile to write to a file from memory.

Be careful with the os.ReadFile because it reads the whole file into memory.

package main

import "os"

func main() {
    b, err := os.ReadFile("input.txt")
    if err != nil {
        log.Fatal(err)
    }

    // `data` contains everything your file does
    // This writes it to the Standard Out
    os.Stdout.Write(data)

    // You can also write it to a file as a whole
    err = os.WriteFile("destination.txt", b, 0644)
    if err != nil {
        log.Fatal(err)
    }
}

I found the nice resource Standard C++ Containers. Probably this is what you all looking for.

VECTOR

Constructors

vector<T> v;              Make an empty vector.                                     O(1)
vector<T> v(n);           Make a vector with N elements.                            O(n)
vector<T> v(n, value);    Make a vector with N elements, initialized to value.      O(n)
vector<T> v(begin, end);  Make a vector and copy the elements from begin to end.    O(n)

Accessors

v[i]          Return (or set) the I'th element.                        O(1)
v.at(i)       Return (or set) the I'th element, with bounds checking.  O(1)
v.size()      Return current number of elements.                       O(1)
v.empty()     Return true if vector is empty.                          O(1)
v.begin()     Return random access iterator to start.                  O(1)
v.end()       Return random access iterator to end.                    O(1)
v.front()     Return the first element.                                O(1)
v.back()      Return the last element.                                 O(1)
v.capacity()  Return maximum number of elements.                       O(1)

Modifiers

v.push_back(value)         Add value to end.                                                O(1) (amortized)
v.insert(iterator, value)  Insert value at the position indexed by iterator.                O(n)
v.pop_back()               Remove value from end.                                           O(1)
v.assign(begin, end)       Clear the container and copy in the elements from begin to end.  O(n)
v.erase(iterator)          Erase value indexed by iterator.                                 O(n)
v.erase(begin, end)        Erase the elements from begin to end.                            O(n)

For other containers, refer to the page.

For currency, I'd suggest:

<div><label>Amount $
    <input type="number" placeholder="0.00" required name="price" min="0" value="0" step="0.01" title="Currency" pattern="^\d+(?:\.\d{1,2})?$" onblur="
this.parentNode.parentNode.style.backgroundColor=/^\d+(?:\.\d{1,2})?$/.test(this.value)?'inherit':'red'
"></label></div>

See http://jsfiddle.net/vx3axsk5/1/

The HTML5 properties "step", "min" and "pattern" will be validated when the form is submit, not onblur. You don't need the step if you have a pattern and you don't need a pattern if you have a step. So you could revert back to step="any" with my code since the pattern will validate it anyways.

If you'd like to validate onblur, I believe giving the user a visual cue is also helpful like coloring the background red. If the user's browser doesn't support type="number" it will fallback to type="text". If the user's browser doesn't support the HTML5 pattern validation, my JavaScript snippet doesn't prevent the form from submitting, but it gives a visual cue. So for people with poor HTML5 support, and people trying to hack into the database with JavaScript disabled or forging HTTP Requests, you need to validate on the server again anyways. The point with validation on the front-end is for a better user experience. So as long as most of your users have a good experience, it's fine to rely on HTML5 features provided the code will still works and you can validate on the back-end.

We can add "AwaitTerminationSeconds" property for both taskExecutor and taskScheduler as below,

<property name="awaitTerminationSeconds" value="${taskExecutor .awaitTerminationSeconds}" />

<property name="awaitTerminationSeconds" value="${taskScheduler .awaitTerminationSeconds}" />

Documentation for "waitForTasksToCompleteOnShutdown" property says, when shutdown is called

"Spring's container shutdown continues while ongoing tasks are being completed. If you want this executor to block and wait for the termination of tasks before the rest of the container continues to shut down - e.g. in order to keep up other resources that your tasks may need -, set the "awaitTerminationSeconds" property instead of or in addition to this property."

https://docs.spring.io/spring/docs/current/javadoc-api/org/springframework/scheduling/concurrent/ExecutorConfigurationSupport.html#setWaitForTasksToCompleteOnShutdown-boolean-

So it is always advised to use waitForTasksToCompleteOnShutdown and awaitTerminationSeconds properties together. Value of awaitTerminationSeconds depends on our application.

python 3 https://docs.python.org/3.5/howto/sorting.html#the-old-way-using-the-cmp-parameter

There are more technical explanations for your question, but if you want a way to think about margin and padding, this analogy might help.

Imagine block elements as picture frames hanging on a wall:

• The photo is the content.
• The matting is the padding.
• The frame moulding is the border.
• The wall is the viewport.
• The space between two frames is the margin.

With this in mind, a good rule of thumb is to use margin when you want to space an element in relationship to other elements on the wall, and padding when you're adjusting the appearance of the element itself. Margin won't change the size of the element, but padding will make the element bigger¹.

¹ You can alter this behavior with the box-sizing attribute.

Not sure if this is the most efficient way, but:

>>> ''.join(c for c in "abc123def456" if c.isdigit())
'123456'

The ''.join part means to combine all the resulting characters together without any characters in between. Then the rest of it is a list comprehension, where (as you can probably guess) we only take the parts of the string that match the condition isdigit.

First I tried from command line;

When I disable "Enable Just My Code" option in Tools -> Options -> Debugging -> General

The problem resolved for me. It is a WCF application, was trying to debug an ashx page. http://blogs.msdn.com/b/zainnab/archive/2010/10/25/understanding-just-my-code.aspx

There are several of this same question (1, 2). One way of doing it is using canvas. Here's a working solution. Here you can see some working examples of using this library.

You can't call a non-static method without first creating an instance of its parent class.

So from the static method, you would have to instantiate a new object...

Vehicle myCar = new Vehicle();

... and then call the non-static method.

myCar.Drive();

You need convert list to numpy array and then reshape:

df = pd.DataFrame(np.array(my_list).reshape(3,3), columns = list("abc"))
print (df)
   a  b  c
0  1  2  3
1  4  5  6
2  7  8  9

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

You're allowed to have more than one return statement, so it's legal to write

if (some_condition) {
  return true;
}
return false;

It's also unnecessary to compare boolean values to true or false, so you can write

if (verifyPwd())  {
  // do_task
}

Edit: Sometimes you can't return early because there's more work to be done. In that case you can declare a boolean variable and set it appropriately inside the conditional blocks.

boolean success = true;

if (some_condition) {
  // Handle the condition.
  success = false;
} else if (some_other_condition) {
  // Handle the other condition.
  success = false;
}
if (another_condition) {
  // Handle the third condition.
}

// Do some more critical things.

return success;

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

Try this

$("#abc").html('<span class = "xyz"> SAMPLE TEXT</span>');

Handle all the css relevant to that span within xyz

For Eclipse, modify project.properties like this: (your path please)

android.library.reference.1=../../../../workspace/appcompat_v7_22

And remove android-support-v4.jar file in your project's libs folder.

'lines' term from your snippet consists of set of strings.

 lines = f.readlines()
 match = re.findall('[A-Z]+', lines)

You cannot send entire lines into the re.findall('pattern',<string>)

You can try to send line by line

 for i in lines:
  match = re.findall('[A-Z]+', i)
  print match

or to convert the entire lines collection into single line (each line seperated by space)

 NEW_LIST=' '.join(lines)
 match=re.findall('[A-Z]+' ,NEW_LIST)
 print match

Invoking javap to read the bytecode

The javap command takes class-names without the .class extension. Try

javap -c ClassName

Converting .class files back to .java files

javap will however not give you the implementations of the methods in java-syntax. It will at most give it to you in JVM bytecode format.

To actually decompile (i.e., do the reverse of javac) you will have to use proper decompiler. See for instance the following related question:

• How do I "decompile" Java class files?

If you use Java and spring MVC you just need to add the following annotation to your method returning your page :

@CrossOrigin(origins = "*")

"*" is to allow your page to be accessible from anywhere. See https://developer.mozilla.org/fr/docs/Web/HTTP/Headers/Access-Control-Allow-Origin for more details about that.

You must have some virtual function declared in one of the parent classes and never implemented in any of the child classes. Make sure that all virtual functions are implemented somewhere in the inheritence chain. If a class's definition includes a pure virtual function that is never implemented, an instance of that class cannot ever be constructed.

If you have GNU awk this is the solution you want:

$ awk '{print $1}' FPAT='"[^"]+"' file
"A B"
"C"
"D"

http://www.jquerybyexample.net/2012/05/open-link-in-new-tab-or-new-popup.html

$(document).ready(function() {
$('A.BLAH').click(function() {
var NWin = window.open($(this).prop('href'), '', 'height=600,width=1000');
if (window.focus)
{
NWin.focus();
}
return false;
});
});

This should work and protect your form from being submitted if the number of files is greater then max_file_number.

$(function() {

  var // Define maximum number of files.
      max_file_number = 3,
      // Define your form id or class or just tag.
      $form = $('form'), 
      // Define your upload field class or id or tag.
      $file_upload = $('#image_upload', $form), 
      // Define your submit class or id or tag.
      $button = $('.submit', $form); 

  // Disable submit button on page ready.
  $button.prop('disabled', 'disabled');

  $file_upload.on('change', function () {
    var number_of_images = $(this)[0].files.length;
    if (number_of_images > max_file_number) {
      alert(`You can upload maximum ${max_file_number} files.`);
      $(this).val('');
      $button.prop('disabled', 'disabled');
    } else {
      $button.prop('disabled', false);
    }
  });
});

The following function will return an array of the parameter names of any function passed in.

var STRIP_COMMENTS = /((\/\/.*$)|(\/\*[\s\S]*?\*\/))/mg;
var ARGUMENT_NAMES = /([^\s,]+)/g;
function getParamNames(func) {
  var fnStr = func.toString().replace(STRIP_COMMENTS, '');
  var result = fnStr.slice(fnStr.indexOf('(')+1, fnStr.indexOf(')')).match(ARGUMENT_NAMES);
  if(result === null)
     result = [];
  return result;
}

Example usage:

getParamNames(getParamNames) // returns ['func']
getParamNames(function (a,b,c,d){}) // returns ['a','b','c','d']
getParamNames(function (a,/*b,c,*/d){}) // returns ['a','d']
getParamNames(function (){}) // returns []

Edit:

With the invent of ES6 this function can be tripped up by default parameters. Here is a quick hack which should work in most cases:

var STRIP_COMMENTS = /(\/\/.*$)|(\/\*[\s\S]*?\*\/)|(\s*=[^,\)]*(('(?:\\'|[^'\r\n])*')|("(?:\\"|[^"\r\n])*"))|(\s*=[^,\)]*))/mg;

I say most cases because there are some things that will trip it up

function (a=4*(5/3), b) {} // returns ['a']

Edit: I also note vikasde wants the parameter values in an array also. This is already provided in a local variable named arguments.

excerpt from https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions_and_function_scope/arguments:

The arguments object is not an Array. It is similar to an Array, but does not have any Array properties except length. For example, it does not have the pop method. However it can be converted to a real Array:

var args = Array.prototype.slice.call(arguments);

If Array generics are available, one can use the following instead:

var args = Array.slice(arguments);

If you aren't actually restricted to keeping all of these elements as sibling nodes you can wrap the ones that go together in another default flex box, and have the container of both use space-between.

.space-between {_x000D_
  border: 1px solid red;_x000D_
  display: flex;_x000D_
  justify-content: space-between;_x000D_
}_x000D_
.default-flex {_x000D_
  border: 1px solid blue;_x000D_
  display: flex;_x000D_
}_x000D_
.child {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  border: 1px solid;_x000D_
}

<div class="space-between">_x000D_
  <div class="child">1</div>_x000D_
  <div class="default-flex">_x000D_
    <div class="child">2</div>_x000D_
    <div class="child">3</div>_x000D_
    <div class="child">4</div>_x000D_
    <div class="child">5</div>_x000D_
  </div>_x000D_
</div>

Or if you were doing the same thing with flex-start and flex-end reversed you just swap the order of the default-flex container and lone child.

Try this code. You don't require the parse function because your data type is JSON so it is return JSON object.

$.ajax({
    url : base_url+"Login/submit",
    type: "POST",
    dataType: "json",
    data : {
        'username': username,
        'password': password
    },
    success: function(data)
    {
        alert(data.status);
    }
});

I did a log file which prints data into text file using "Winston" log. The source code is here below,

There is a proprietary plugin called "Neptune" which says that it will allow you to use IE Tab functionality in Chrome on Windows.

Meadroid do this because they have ActiveX controls which they have written and they want them to be able to work in any browser, and they explicitly mention Chrome in the list of supported browsers for enabling ActiveX with this.

There is also a modified version of Chrome, called ChromePlus, which includes IETab, among other extra features.

I've not used either of these personally, but they look like they'll do what you want. I'd be interested to hear if they work out for you, as I know of other people who want to be able to use IEtab in Chrome :)

Subset is your safest and easiest answer.

subset(dataframe, A==B & E!=0)

Real data example with mtcars

subset(mtcars, cyl==6 & am!=0)

To align a text use the following:

StringFormat sf = new StringFormat();
sf.LineAlignment = StringAlignment.Center;
sf.Alignment = StringAlignment.Center;
e.Graphics.DrawString("My String", this.Font, Brushes.Black, ClientRectangle, sf);

Please note that the text here is aligned in the given bounds. In this sample this is the ClientRectangle.

Using pure java-script, here is a working code example

<input type="checkbox" name="fruit1" checked/>
<input type="checkbox" name="fruit2" checked />
<input type="checkbox" name="fruit3" checked />
<input type="checkbox" name="other1" checked />
<input type="checkbox" name="other2" checked />
<br>
<input type="button" name="check" value="count checked checkboxes name starts with fruit*" onClick="checkboxes();" />


<script>
function checkboxes()
{
var inputElems = document.getElementsByTagName("input"),
count = 0;
for (var i=0; i<inputElems.length; i++) {       
if (inputElems[i].type == "checkbox" && inputElems[i].checked == true && 
inputElems[i].name.indexOf('fruit') == 0) 
{
count++;

}

}
alert(count);
}
</script>

The OP answered this question to change the default timezone for a single instance of a running JVM, set the user.timezone system property:

java -Duser.timezone=GMT ... <main-class>

If you need to set specific time zones when retrieving Date/Time/Timestamp objects from a database ResultSet, use the second form of the getXXX methods that takes a Calendar object:

Calendar tzCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
ResultSet rs = ...;
while (rs.next()) {
    Date dateValue = rs.getDate("DateColumn", tzCal);
    // Other fields and calculations
}

Or, setting the date in a PreparedStatement:

Calendar tzCal = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
PreparedStatement ps = conn.createPreparedStatement("update ...");
ps.setDate("DateColumn", dateValue, tzCal);
// Other assignments
ps.executeUpdate();

These will ensure that the value stored in the database is consistent when the database column does not keep timezone information.

The java.util.Date and java.sql.Date classes store the actual time (milliseconds) in UTC. To format these on output to another timezone, use SimpleDateFormat. You can also associate a timezone with the value using a Calendar object:

TimeZone tz = TimeZone.getTimeZone("<local-time-zone>");
//...
Date dateValue = rs.getDate("DateColumn");
Calendar calValue = Calendar.getInstance(tz);
calValue.setTime(dateValue);

You're trying to pass file objects as filenames. Try using

infile = '110331_HS1A_1_rtTA.result'
outfile = '2.txt'

at the top of your code.

(Not only does the doubled usage of open() cause that problem with trying to open the file again, it also means that infile and outfile are never closed during the course of execution, though they'll probably get closed once the program ends.)

If necessary to keep the inner sorting:

SELECT 1 as type, field1 FROM table1 
UNION 
SELECT 2 as type, field1 FROM table2 
ORDER BY type, field1

Every derived table (AKA sub-query) must indeed have an alias. I.e. each query in brackets must be given an alias (AS whatever), which can the be used to refer to it in the rest of the outer query.

SELECT ID FROM (
    SELECT ID, msisdn FROM (
        SELECT * FROM TT2
    ) AS T
) AS T

In your case, of course, the entire query could be replaced with:

SELECT ID FROM TT2

use this command on your script file after copying it to Linux/Unix

perl -pi -e 's/\r//' scriptfilename

Limit - 30 symbols. Username must contains only letters, numbers, periods and underscores.

That didn't work for me, I used some code parts from web, what I did:

new activity: FullScreenImage with:

package yourpackagename;
import yourpackagename.R;


import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

public class FullScreenImage  extends Activity {


@SuppressLint("NewApi")



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.layout_full);

    Bundle extras = getIntent().getExtras();
    Bitmap bmp = (Bitmap) extras.getParcelable("imagebitmap");

    ImageView imgDisplay;
    Button btnClose;


    imgDisplay = (ImageView) findViewById(R.id.imgDisplay);
    btnClose = (Button) findViewById(R.id.btnClose);


   btnClose.setOnClickListener(new View.OnClickListener() {            
    public void onClick(View v) {
    FullScreenImage.this.finish();
}
});


 imgDisplay.setImageBitmap(bmp );

}   


}

Then create a xml: layout_full

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

<ImageView
    android:id="@+id/imgDisplay"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:scaleType="fitCenter" />

<Button
    android:id="@+id/btnClose"
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:layout_marginRight="15dp"
    android:layout_marginTop="15dp"
    android:paddingTop="2dp"
    android:paddingBottom="2dp"
    android:textColor="#ffffff"
    android:text="Close" />

   </RelativeLayout>

And finally, send the image name from your mainactivity

   final ImageView im = (ImageView)findViewById(R.id.imageView1) ; 
   im.setBackgroundDrawable(getResources().getDrawable(id1));

   im.setOnClickListener(new OnClickListener() {

      @Override
       public void onClick(View view) {
       Intent intent = new Intent(NAMEOFYOURCURRENTACTIVITY.this, FullScreenImage.class);

       im.buildDrawingCache();
       Bitmap image= im.getDrawingCache();

       Bundle extras = new Bundle();
       extras.putParcelable("imagebitmap", image);
       intent.putExtras(extras);
       startActivity(intent);

                                }
                            });

This is your safest way to do it:

$id =101;
//$user_id=25;
$criteria=new CDbCriteria;
$criteria->condition="email_id < :email_id";
//$criteria->addCondition("user_id=:user_id");
$criteria->params=array(
  ':email_id' => $id,
  //':user_id' => $user_id,
);
$comments=EmailArchive::model()->findAll($criteria);

Note that if you comment out the commented lines you get a way to add more filtering to your search.

After this it is recommend to check if there is any data returned like:

if (isset($comments)) { // We found some comments, we can sleep well tonight
  // do comments process or whatever
}

In python v3.x you should go to : Tools->Build System->New Build System.

Then, it pop up the untitled.sublime-build window in sublime text editor.Enter setting as:

{

    "cmd": ["path_to_the_python.exe","-u", "$file"],
    "file_regex": "^[ ]*File \"(...*?)\", line ([0-9]*)",
    "selector": "source.python"
}

To see the path, Type following in terminal as:

python
>>> import sys
>>>print(sys.executable)

You can make more than one Build System but it should default save inside Packages of Sublime text with .sublime-build extension.

Then, select the new Build System and press cltr+b or other based on your os.

Note: if you want to delete file only from git use below:

git rm --cached file1.txt

If you want to delete also from hard disk:

git rm file1.txt

If you want to remove a folder(the folder may contain few files) so, you should remove using recursive command, as below:

git rm -r foldername

If you want to remove a folder inside another folder

git rm -r parentFolder/childFolder

Then, you can commit and push as usual. However, if you want to recover deleted folder, you can follow this: recover deleted files from git is possible.

From doc:

git rm [-f | --force] [-n] [-r] [--cached] [--ignore-unmatch] [--quiet] [--] <file>…?

OPTIONS

<file>…?

Files to remove. Fileglobs (e.g. *.c) can be given to remove all matching files. If you want Git to expand file glob characters, you

may need to shell-escape them. A leading directory name (e.g. dir to remove dir/file1 and dir/file2) can be given to remove all files in the directory, and recursively all sub-directories, but this requires the -r option to be explicitly given. -f --force

Override the up-to-date check.

-n --dry-run

Don’t actually remove any file(s). Instead, just show if they exist in the index and would otherwise be removed by the command.

-r

Allow recursive removal when a leading directory name is given.

--

This option can be used to separate command-line options from the list of files, (useful when filenames might be mistaken for

command-line options). --cached

Use this option to unstage and remove paths only from the index. Working tree files, whether modified or not, will be left alone.

--ignore-unmatch

Exit with a zero status even if no files matched.

-q --quiet

git rm normally outputs one line (in the form of an rm command) for each file removed. This option suppresses that output.

Read more on official doc.

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

DEMO

See the Parameter Expansion section in the Bash man page. A[@] returns the contents of the array, :1:2 takes a slice of length 2, starting at index 1.

A=( foo bar "a  b c" 42 )
B=("${A[@]:1:2}")
C=("${A[@]:1}")       # slice to the end of the array
echo "${B[@]}"        # bar a  b c
echo "${B[1]}"        # a  b c
echo "${C[@]}"        # bar a  b c 42
echo "${C[@]: -2:2}"  # a  b c 42 # The space before the - is necesssary

Note that the fact that "a b c" is one array element (and that it contains an extra space) is preserved.

1) == evaluates reference equality in this case
2) im not too sure about the equals, but why not simply overriding the compare method and plant it inside MyClass?

I would recommend you to reset all the HTML elements before writing your css with:

* {
    margin: 0;
    padding: 0;
} 

After that, you can write your custom css, without any problems.

we can use different types of system fonts like below

myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: 17)
myButton.titleLabel?.font = UIFont.italicSystemFont(ofSize:UIFont.smallSystemFontSize)
myButton.titleLabel?.font = UIFont.boldSystemFont(ofSize: UIFont.buttonFontSize)

and your custom font like below

    myButton.titleLabel?.font = UIFont(name: "Helvetica", size:12)

This is a trick,

function OpenInNewTab(url) {

  var win = window.open(url, '_blank');
  win.focus();
}

In most cases, this should happen directly in the onclick handler for the link to prevent pop-up blockers, and the default "new window" behavior. You could do it this way, or by adding an event listener to your DOM object.

<div onclick="OpenInNewTab();">Something To Click On</div>

Yes, you have to get all records, update them and then call SaveChanges.

Try

SELECT NAME, count(*) as NUM FROM tbl GROUP BY NAME

SQL FIDDLE

You can use the LocalForward directive in your host yam section of ~/.ssh/config:

LocalForward 5901 computer.myHost.edu:5901

You can do that in this way:

ORDER BY `products`.`product_category_id` DESC ,`naam` ASC

Have a look at ORDER BY Optimization

To compare, there are more options:

import (
    "fmt"
    "regexp"
    "strings"
)

const (
    str    = "something"
    substr = "some"
)

// 1. Contains
res := strings.Contains(str, substr)
fmt.Println(res) // true

// 2. Index: check the index of the first instance of substr in str, or -1 if substr is not present
i := strings.Index(str, substr)
fmt.Println(i) // 0

// 3. Split by substr and check len of the slice, or length is 1 if substr is not present
ss := strings.Split(str, substr)
fmt.Println(len(ss)) // 2

// 4. Check number of non-overlapping instances of substr in str
c := strings.Count(str, substr)
fmt.Println(c) // 1

// 5. RegExp
matched, _ := regexp.MatchString(substr, str)
fmt.Println(matched) // true

// 6. Compiled RegExp
re = regexp.MustCompile(substr)
res = re.MatchString(str)
fmt.Println(res) // true

Benchmarks: Contains internally calls Index, so the speed is almost the same (btw Go 1.11.5 showed a bit bigger difference than on Go 1.14.3).

As of .NET Core 2.0, the constructor Dictionary<TKey,TValue>(IEnumerable<KeyValuePair<TKey,TValue>>) now exists.

Use:

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

(function(con) {
    var oDate = new Date();
    var nHrs = oDate.getHours();
    var nMin = oDate.getMinutes();
    var nDate = oDate.getDate();
    var nMnth = oDate.getMonth();
    var nYear = oDate.getFullYear();

    con.log(nDate + ' - ' + nMnth + ' - ' + nYear);
    con.log(nHrs + ' : ' + nMin);
})(console);

This produces an output like:

30 - 8 - 2013
21 : 30

Perhaps you may refer documentation on Date object at MDN for more information

I have provide two methods for doing so for minutes as well as for years and hours if you want to see more examples:

import datetime
print(datetime.datetime.now())
print(datetime.datetime.now() - datetime.timedelta(minutes = 15))
print(datetime.datetime.now() + datetime.timedelta(minutes = -15))
print(datetime.timedelta(hours = 5))
print(datetime.datetime.now() + datetime.timedelta(days = 3))
print(datetime.datetime.now() + datetime.timedelta(days = -9))
print(datetime.datetime.now() - datetime.timedelta(days = 9))

I get the following results:

2016-06-03 16:04:03.706615
2016-06-03 15:49:03.706622

You can change the listen port as per your requirement. This task can be accomplished in two diffrent ways. By changing config.xml file By changing in admin console Change the listen port in config.xml as per your requirement and bounce the domain. Admin Console Login to AdminConsole->Server->Configuration->ListenPort (Change it) Note: It is a bad practice to edit config.xml and try to edit in admin console(It's a good practise as well)

The sad state of "record separators" or "line terminators" is a legacy of the dark ages of computing.

Now, we take it for granted that anything we want to represent is in some way structured data and conforms to various abstractions that define lines, files, protocols, messages, markup, whatever.

But once upon a time this wasn't exactly true. Applications built-in control characters and device-specific processing. The brain-dead systems that required both CR and LF simply had no abstraction for record separators or line terminators. The CR was necessary in order to get the teletype or video display to return to column one and the LF (today, NL, same code) was necessary to get it to advance to the next line. I guess the idea of doing something other than dumping the raw data to the device was too complex.

Unix and Mac actually specified an abstraction for the line end, imagine that. Sadly, they specified different ones. (Unix, ahem, came first.) And naturally, they used a control code that was already "close" to S.O.P.

Since almost all of our operating software today is a descendent of Unix, Mac, or MS operating SW, we are stuck with the line ending confusion.

My answer seems like less code and it works for me:

      }
      
      pick() {

    }
    
    class Gross extends Classes([Nose,Ear]) {
      constructor() {
        super();
        this.gross = true;
      }
    }
    
    function Classes(bases) {
      class Bases {
        constructor() {
          bases.forEach(base => Object.assign(this, new base()));
        }
      }
      bases.forEach(base => {
        Object.getOwnPropertyNames(base.prototype)
        .filter(prop => prop != 'constructor')
        .forEach(prop => Bases.prototype[prop] = base.prototype[prop])
      })
      return Bases;
    }

    
    // test it
    
    var grossMan = new Gross();
    grossMan.pick(); // eww
    grossMan.dig();  // yuck!

The main (very interesting) difference for me is that:
"string" & Null -> "string"
while
"string" + Null -> Null

But that's probably more useful in database apps like Access.

Updated for Swift :

Used below code for Email, Name, Mobile and Password Validation;

// Name validation
func isValidName(_ nameString: String) -> Bool {

    var returnValue = true
    let mobileRegEx =  "[A-Za-z]{2}"  // "^[A-Z0-9a-z.-_]{5}$"

    do {
        let regex = try NSRegularExpression(pattern: mobileRegEx)
        let nsString = nameString as NSString
        let results = regex.matches(in: nameString, range: NSRange(location: 0, length: nsString.length))

        if results.count == 0
        {
            returnValue = false
        }

    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        returnValue = false
    }

    return  returnValue
}

// password validation
func isValidPassword(_ PasswordString: String) -> Bool {

    var returnValue = true
    let mobileRegEx =  "[A-Za-z0-9.-_@#$!%&*]{5,15}$"  // "^[A-Z0-9a-z.-_]{5}$"

    do {
        let regex = try NSRegularExpression(pattern: mobileRegEx)
        let nsString = PasswordString as NSString
        let results = regex.matches(in: PasswordString, range: NSRange(location: 0, length: nsString.length))

        if results.count == 0
        {
            returnValue = false
        }

    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        returnValue = false
    }

    return  returnValue
}

// email validaton
func isValidEmailAddress(_ emailAddressString: String) -> Bool {

    var returnValue = true
    let emailRegEx = "[A-Z0-9a-z.-_]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,3}"

    do {
        let regex = try NSRegularExpression(pattern: emailRegEx)
        let nsString = emailAddressString as NSString
        let results = regex.matches(in: emailAddressString, range: NSRange(location: 0, length: nsString.length))

        if results.count == 0
        {
            returnValue = false
        }

    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        returnValue = false
    }

    return  returnValue
}

// mobile no. validation
func isValidPhoneNumber(_ phoneNumberString: String) -> Bool {

    var returnValue = true
    //        let mobileRegEx = "^[789][0-9]{9,11}$"
    let mobileRegEx = "^[0-9]{10}$"

    do {
        let regex = try NSRegularExpression(pattern: mobileRegEx)
        let nsString = phoneNumberString as NSString
        let results = regex.matches(in: phoneNumberString, range: NSRange(location: 0, length: nsString.length))

        if results.count == 0
        {
            returnValue = false
        }

    } catch let error as NSError {
        print("invalid regex: \(error.localizedDescription)")
        returnValue = false
    }

    return  returnValue
}

//How to use?

let isFullNameValid = isValidName("ray")

if isFullNameValid{
    print("Valid name...")
}else{
    print("Invalid name...")
}

My suggestion is for you to do some automated tests first. Use selenium for it.

Then deploy selenium grid to test in multiple computers at the same time.

Although Selenium as an automated test tool will run quite fast, making a mini stress test. If you put the same automation running on a couple of computers on your network at the same time you'll be able to see how it behaves.

If you want to record response timings, they have a cool api you can use to write some scripts to run your automations.

Edit: Selenium is quite easy to use, and it does asserts to page contents if you want to test the contents. It also copies your movement through the page if you wish (this would be my suggestion) just navigate the page a lot, and then save it for automation. Avoid putting asserts so selenium might run faster.

If you run your commands in a shell you can write something like "java -cp" and add any directories you want separated by ":" if java doesnt find something in one directory it will go try and find them in the other directories, that is what I do.

Simply in Code Behind Page use:-

SqlConnection con = new SqlConnection("Data Source = DellPC; Initial Catalog = Account; user = sa; password = admin");

It Should Work Just Fine

Well Curl could be a better option for json representation but in that case it would be difficult to understand the structure of json because its in command line. if you want to get your json on browser you simply remove all the XML Annotations like -

@XmlRootElement(name="person")
@XmlAccessorType(XmlAccessType.NONE)
@XmlAttribute
@XmlElement

from your model class and than run the same url, you have used for xml representation.

Make sure that you have jacson-databind dependency in your pom.xml

<dependency>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-databind</artifactId>
  <version>2.4.1</version>
</dependency>

constructor(private router: Router) {}

navigateOnParent() {
  this.router.navigate(['../some-path-on-parent']);
}

The router supports

• absolute paths /xxx - started on the router of the root component
• relative paths xxx - started on the router of the current component
• relative paths ../xxx - started on the parent router of the current component

Exception : java.net.ConnectException

This means your request didn't getting response from server in stipulated time. And their are some reasons for this exception:

• Too many requests overloading the server
• Request packet loss because of wrong network configuration or line overload
• Sometimes firewall consume request packet before sever getting
• Also depends on thread connection pool configuration and current status of connection pool
• Response packet lost during transition

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

float is the closest equivalent.

SqlDbType Enumeration

For Lat/Long as OP mentioned.

A metre is 1/40,000,000 of the latitude, 1 second is around 30 metres. Float/double give you 15 significant figures. With some quick and dodgy mental arithmetic... the rounding/approximation errors would be the about the length of this fill stop -> "."

From the simulator, in iPad mode:

and in iPhone mode:

Mozilla/5.0 (iPhone; U; CPU iPhone OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.20 (KHTML, like Gecko) Mobile/7B298g

I don't know how reliable the simulator is, but it seems you can't detect whether the device is iPad just from the user-agent string.

(Note: I'm on Snow Leopard which the User Agent string for Safari is

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_2; en-us) AppleWebKit/531.21.8 (KHTML, like Gecko) Version/4.0.4 Safari/531.21.10

)

I've solved this problem in this way.

String dateUTC = rs.getString("date"); //UTC
DateTime date;
DateTimeFormatter dateTimeFormatter = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss.SSS").withZoneUTC();
date = dateTimeFormatter.parseDateTime(dateUTC);

In this way you ignore the server TimeZone forcing your chosen TimeZone.

Here's a way to do it:

// The method to call
void Foo()
{
}


Action action = Foo;
action.BeginInvoke(ar => action.EndInvoke(ar), null);

Of course you need to replace Action by another type of delegate if the method has a different signature

UPDATE 2016: Somewhere between July 2015 and January 2016 the printing feature request that I wrote about in 2014 was removed. The original answer is below, with the relevant links changed to the latest working versions in the Web Archive:

Original 2014 Answer

Printing in Sublime Text is a feature that has been requested for about 4 years (as of 2014), with 1600+ supporting votes and 160+ comments in the discussion below. For something around 6000 feature requests this is in the top 5.

See the original, still open, feature request:

• Printing - It should be possible to print files on the official UserEcho forum of Sublime Text

Judging from the feature request (still open with no official answer) it seems unlikely that printing will ever get implemented in version 3 (as others have suggested) or in any version at all.

The discussion below this feature request may give some insight on why printing is not supported and whether or not it has a chance to get supported in the future.

Maybe if more people vote or comment it will change in the future. (See Update 2016 below for an up-to-date list of feature requests)

Some workarounds were suggested, the most popular advices were to use some other editor for printing (eg. Brackets, Atom, gedit, Notepad++) or to use some 3rd party plugins that reportedly don't work well or at all.

In general there is a strong opposition to adding printing as a native feature of Sublime Text which for such a universal functionality among text editors seems surprising, but may nevertheless shed some light on this issue.

Meanwhile, there are many free editors that can print (in fact I cannot think of a single one that couldn't) so it is easy to use some other editor whenever a need for printing arises.

Update 2016

Since the feature request described above was removed (please comment if anyone knows why) here is an up-to-date list of some other places to find more info about printing in Sublime Text:

• Sublime Text feature request #25170: Printing (Web Archive, July 2015)
• Sublime Text feature request #128509: Please add printing features!
• Sublime Text feature request #150254: No print option in Sublime Text2
• Sublime Text feature request #149563: Printing and pretty-printing required
• Sublime Text feature request #128718: Is Sublime Text unable to print?
• Sublime Text feature request #380352: Printing
• Sublime Text feature request #203216: PRINT PRINT PRINT
• Sublime Text feature request #128718: Is there a menu option to Print the file?
• Other Sublime Text feature requests related to printing
• Printing from Sublime - Sublime Forum

Since the original feature request #25170 was removed, you should vote and comment in the other feature requests about printing instead.

import csv

with open('file_name.csv', 'w') as csv_file:
    writer = csv.writer(csv_file)
    writer.writerow(('colum1', 'colum2', 'colum3'))
    for key, value in dictionary.items():
        writer.writerow([key, value[0], value[1]])

This would be the simplest way to write data to .csv file

I used the below. The genre element will start where the DJ element ends,

<div>
<div style="width:50%; float:left">DJ</div>
<div>genre</div>
</div>

pardon the inline css.

I did use following solution to this:

findAllByStartDateLessThanEqualAndEndDateGreaterThanEqual(OffsetDateTime endDate, OffsetDateTime startDate);

I like rest-client a lot for the purposes you described. It's a Java application to test REST-based web services.

I'm going to take a stab in the dark and guess you're talking about Windows. In a nutshell, kernel mode has full access to hardware, but user mode doesn't. For instance, many if not most device drivers are written in kernel mode because they need to control finer details of their hardware.

See also this wikibook.

ListenForClients is getting invoked twice (on two different threads) - once from the constructor, once from the explicit method call in Main. When two instances of the TcpListener try to listen on the same port, you get that error.

I was having the similar issue when using VirtualBox on Ubuntu 12.04LTS. Now if anyone is using or has ever used Ubuntu, you might be aware that how things are hard sometimes when using shortcut keys in Ubuntu. For me, when i was trying to revert back the Host key, it was just not happening and the shortcut keys won't just work. I even tried the command line option to revert back the scale mode and it won't work either. Finally i found the following when all the other options fails:

Fix the Scale Mode Issue in Oracle VirtualBox in Ubuntu using the following steps:

1. Close all virtual machines and VirtualBox windows.

2. Find your machine config files (i.e. /home/<username>/VirtualBox VMs/ANKSVM) where ANKSVM is your VM Name and edit and change the following in ANKSVM.vbox and ANKSVM.vbox-prev files:

3. Edit the line: <ExtraDataItem name="GUI/Scale" value="on"/> to <ExtraDataItem name="GUI/Scale" value="off"/>

4. Restart VirtualBox

You are done.

This works every time specially when all other options fails like how it happened for me.

The following is inspired by Simon's answer. It's self-contained (doesn't require a separate format file), which makes it great for inclusion into .bashrc.

curl_time() {
    curl -so /dev/null -w "\
   namelookup:  %{time_namelookup}s\n\
      connect:  %{time_connect}s\n\
   appconnect:  %{time_appconnect}s\n\
  pretransfer:  %{time_pretransfer}s\n\
     redirect:  %{time_redirect}s\n\
starttransfer:  %{time_starttransfer}s\n\
-------------------------\n\
        total:  %{time_total}s\n" "$@"
}

Futhermore, it should work with all arguments that curl normally takes, since the "$@" just passes them through. For example, you can do:

curl_time -X POST -H "Content-Type: application/json" -d '{"key": "val"}' https://postman-echo.com/post

Output:

   namelookup:  0,125000s
      connect:  0,250000s
   appconnect:  0,609000s
  pretransfer:  0,609000s
     redirect:  0,000000s
starttransfer:  0,719000s
-------------------------
        total:  0,719000s

You can modify the path on the config.xml file in the default directory

<projectNamingStrategy class="jenkins.model.ProjectNamingStrategy$DefaultProjectNamingStrategy"/>
<workspaceDir>D:/Workspace/${ITEM_FULL_NAME}</workspaceDir>
<buildsDir>D:/Logs/${ITEM_ROOTDIR}/Build</buildsDir>

As explained @Yaroslav Stavnichiy if a service is marked as transactional spring tries to handle transaction itself. If any exception occurs then a rollback operation performed. If in your scenario ServiceUser.method() is not performing any transactional operation you can use @Transactional.TxType annotation. 'NEVER' option is used to manage that method outside transactional context.

Transactional.TxType reference doc is here.

use text transform property in your style tag

textTransform:'uppercase'

Use @@ROWCOUNT:

SELECT * FROM service s WHERE s.service_id = ?;

IF @@ROWCOUNT > 0 
   -- do stuff here.....

According to SQL Server Books Online:

Returns the number of rows affected by the last statement. If the number of rows is more than 2 billion, use ROWCOUNT_BIG.

maybe the unbind method will work for you

$("#myimage").unbind("click");

That's a fine solution. I just wanted to add

set -e

as a rudimentary error mechanism. It will immediately stop your script if a simple command fails. I think this should have been the default behavior: since such errors almost always signify something unexpected, it is not really 'sane' to keep executing the following commands.

For Kotlin on fragment just do this

activity?.runOnUiThread(Runnable {
        //on main thread
    })

The difference is the name of the mangled identifier (_ZN12_GLOBAL__N_11bE vs _ZL1b , which doesn't really matter, but both of them are assembled to local symbols in the symbol table (absence of .global asm directive).

#include<iostream>
namespace {
   int a = 3;
}

static int b = 4;
int c = 5;

int main (){
    std::cout << a << b << c;
}

        .data
        .align 4
        .type   _ZN12_GLOBAL__N_11aE, @object
        .size   _ZN12_GLOBAL__N_11aE, 4
_ZN12_GLOBAL__N_11aE:
        .long   3
        .align 4
        .type   _ZL1b, @object
        .size   _ZL1b, 4
_ZL1b:
        .long   4
        .globl  c
        .align 4
        .type   c, @object
        .size   c, 4
c:
        .long   5
        .text

As for a nested anonymous namespace:

namespace {
   namespace {
       int a = 3;
    }
}

        .data
        .align 4
        .type   _ZN12_GLOBAL__N_112_GLOBAL__N_11aE, @object
        .size   _ZN12_GLOBAL__N_112_GLOBAL__N_11aE, 4
_ZN12_GLOBAL__N_112_GLOBAL__N_11aE:
        .long   3

All 1st level anonymous namespaces in the translation unit are combined with each other, All 2nd level nested anonymous namespaces in the translation unit are combined with each other

You can also have a nested namespace or nested inline namespace in an anonymous namespace

namespace {
   namespace A {
       int a = 3;
    }
}

        .data
        .align 4
        .type   _ZN12_GLOBAL__N_11A1aE, @object
        .size   _ZN12_GLOBAL__N_11A1aE, 4
_ZN12_GLOBAL__N_11A1aE:
        .long   3

which for the record demangles as:
        .data
        .align 4
        .type   (anonymous namespace)::A::a, @object
        .size   (anonymous namespace)::A::a, 4
(anonymous namespace)::A::a:
        .long   3

//inline has the same output

You can also have anonymous inline namespaces, but as far as I can tell, inline on an anonymous namespace has 0 effect

inline namespace {
   inline namespace {
       int a = 3;
    }
}

_ZL1b: _Z means this is a mangled identifier. L means it is a local symbol through static. 1 is the length of the identifier b and then the identifier b

_ZN12_GLOBAL__N_11aE _Z means this is a mangled identifier. N means this is a namespace 12 is the length of the anonymous namespace name _GLOBAL__N_1, then the anonymous namespace name _GLOBAL__N_1, then 1 is the length of the identifier a, a is the identifier a and E closes the identifier that resides in a namespace.

_ZN12_GLOBAL__N_11A1aE is the same as above except there's another namespace level in it 1A

A couple of general tips (besides the DOS line ending issue):

cat is for concatenating files, it's not the only tool that can read files! If a command doesn't read files then use redirection like command < file.

You can set the field separator with the -F option so instead of:

cat foo | awk 'BEGIN{FS="|"} {print $2 " " $1}' 

Try:

awk -F'|' '{print $2" "$1}' foo 

This will output:

com.emailclient.account [email protected]
com.socialsite.auth.accoun [email protected]

To get the desired output you could do a variety of things. I'd probably split() the second field:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file
emailclient [email protected]
socialsite [email protected]

Finally to get the first character converted to uppercase is a bit of a pain in awk as you don't have a nice built in ucfirst() function:

awk -F'|' '{split($2,a,".");print toupper(substr(a[2],1,1)) substr(a[2],2),$1}' file
Emailclient [email protected]
Socialsite [email protected]

If you want something more concise (although you give up a sub-process) you could do:

awk -F'|' '{split($2,a,".");print a[2]" "$1}' file | sed 's/^./\U&/'
Emailclient [email protected]
Socialsite [email protected]

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

The answers here work for just 2 cells, but as soon as those columns have more in them it can lead to a bit more complexity. I think I've found a generalized solution for any number of cells in multiple columns.

#Goals Get a vertical sequence of tags on mobile to arrange themselves in whatever order the design calls for on tablet/desktop. In this concrete example, one tag must enter flow earlier than it normally would, and another later than it normally would.

##Mobile

[1 headline]
[2 image]
[3 qty]
[4 caption]
[5 desc]

##Tablet+

[2 image  ][1 headline]
[         ][3 qty     ]
[         ][5 desc    ]
[4 caption][          ]
[         ][          ]

So headline needs to shuffle right on tablet+, and technically, so does desc - it sits above the caption tag that precedes it on mobile. You'll see in a moment 4 caption is in trouble too.

Let's assume every cell could vary in height, and needs to be flush top-to-bottom with its next cell (ruling out weak tricks like a table).

As with all Bootstrap Grid problems step 1 is to realize the HTML has to be in mobile-order, 1 2 3 4 5, on the page. Then, determine how to get tablet/desktop to reorder itself in this way - ideally without Javascript.

The solution to get 1 headline and 3 qty to sit to the right not the left is to simply set them both pull-right. This applies CSS float: right, meaning they find the first open space they'll fit to the right. You can think of the browser's CSS processor working in the following order: 1 fits in to the right top corner. 2 is next and is regular (float: left), so it goes to top-left corner. Then 3, which is float: right so it leaps over underneath 1.

But this solution wasn't enough for 4 caption; because the right 2 cells are so short 2 image on the left tends to be longer than the both of them combined. Bootstrap Grid is a glorified float hack, meaning 4 caption is float: left. With 2 image occupying so much room on the left, 4 caption attempts to fit in the next available space - often the right column, not the left where we wanted it.

The solution here (and more generally for any issue like this) was to add a hack tag, hidden on mobile, that exists on tablet+ to push caption out, that then gets covered up by a negative margin - like this:

[2 image  ][1 headline]
[         ][3 qty     ]
[         ][4 hack    ]
[5 caption][6 desc ^^^]
[         ][          ]

http://jsfiddle.net/b9chris/52VtD/16633/

HTML:

<div id=headline class="col-xs-12 col-sm-6 pull-right">Product Headline</div>
<div id=image class="col-xs-12 col-sm-6">Product Image</div>
<div id=qty class="col-xs-12 col-sm-6 pull-right">Qty, Add to cart</div>
<div id=hack class="hidden-xs col-sm-6">Hack</div>
<div id=caption class="col-xs-12 col-sm-6">Product image caption</div>
<div id=desc class="col-xs-12 col-sm-6 pull-right">Product description</div>

CSS:

#hack { height: 50px; }

@media (min-width: @screen-sm) {
    #desc { margin-top: -50px; }
}

So, the generalized solution here is to add hack tags that can disappear on mobile. On tablet+ the hack tags allow displayed tags to appear earlier or later in the flow, then get pulled up or down to cover up those hack tags.

Note: I've used fixed heights for the sake of the simple example in the linked jsfiddle, but the actual site content I was working on varies in height in all 5 tags. It renders properly with relatively large variance in tag heights, especially image and desc.

Note 2: Depending on your layout, you may have a consistent enough column order on tablet+ (or larger resolutions), that you can avoid use of hack tags, using margin-bottom instead, like so:

Note 3: This uses Bootstrap 3. Bootstrap 4 uses a different grid set, and won't work with these examples.

http://jsfiddle.net/b9chris/52VtD/16632/

.val() does not return an array from a DOM element: $('#fruit') is going to find the element in the document with an ID of #fruit and get its value (if it has a value).

DIV is a generic block level container that can contain any other block or inline elements, including other DIV elements, whereas P is to wrap paragraphs (text).

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0
    -- Is empty or NULL
ELSE
    -- Is not empty and is not NULL

Use setRoundingMode, set the RoundingMode explicitly to handle your issue with the half-even round, then use the format pattern for your required output.

Example:

DecimalFormat df = new DecimalFormat("#.####");
df.setRoundingMode(RoundingMode.CEILING);
for (Number n : Arrays.asList(12, 123.12345, 0.23, 0.1, 2341234.212431324)) {
    Double d = n.doubleValue();
    System.out.println(df.format(d));
}

gives the output:

12
123.1235
0.23
0.1
2341234.2125

EDIT: The original answer does not address the accuracy of the double values. That is fine if you don't care much whether it rounds up or down. But if you want accurate rounding, then you need to take the expected accuracy of the values into account. Floating point values have a binary representation internally. That means that a value like 2.7735 does not actually have that exact value internally. It can be slightly larger or slightly smaller. If the internal value is slightly smaller, then it will not round up to 2.7740. To remedy that situation, you need to be aware of the accuracy of the values that you are working with, and add or subtract that value before rounding. For example, when you know that your values are accurate up to 6 digits, then to round half-way values up, add that accuracy to the value:

Double d = n.doubleValue() + 1e-6;

To round down, subtract the accuracy.

I have a stupid idea:

public class Pegasus {
    private Horse horseFeatures; 
    private Bird birdFeatures; 

   public Pegasus(Horse horse, Bird bird) {
     this.horseFeatures = horse;
     this.birdFeatures = bird;
   }

  public void jump() {
    horseFeatures.jump();
  }

  public void fly() {
    birdFeatures.fly();
  }
}

In fact, xargs can run commands in parallel for you. There is a special -P max_procs command-line option for that. See man xargs.

I believe it may be related to a issue in which Microsoft released a update to the MScomCtlLib which was incorrectly patched by microsoft, causing registry errors.

I believe if you follow the advice laid out in:

https://support.microsoft.com/fr-fr/kb/2597986

Firefox Screenshots is a new tool that ships with Firefox. It is not a developer tool, it is aimed at end-users of the browser.

To take a screenshot, click on the page actions menu in the address bar, and click "take a screenshot". If you then click "Save full page", it will save the full page, scrolling for you.

Based on Lucio's code, I made a module. It will return an away with all the files with specific extensions under the one. Just post it here in case anybody needs it.

var path = require('path'), 
    fs   = require('fs');


/**
 * Find all files recursively in specific folder with specific extension, e.g:
 * findFilesInDir('./project/src', '.html') ==> ['./project/src/a.html','./project/src/build/index.html']
 * @param  {String} startPath    Path relative to this file or other file which requires this files
 * @param  {String} filter       Extension name, e.g: '.html'
 * @return {Array}               Result files with path string in an array
 */
function findFilesInDir(startPath,filter){

    var results = [];

    if (!fs.existsSync(startPath)){
        console.log("no dir ",startPath);
        return;
    }

    var files=fs.readdirSync(startPath);
    for(var i=0;i<files.length;i++){
        var filename=path.join(startPath,files[i]);
        var stat = fs.lstatSync(filename);
        if (stat.isDirectory()){
            results = results.concat(findFilesInDir(filename,filter)); //recurse
        }
        else if (filename.indexOf(filter)>=0) {
            console.log('-- found: ',filename);
            results.push(filename);
        }
    }
    return results;
}

module.exports = findFilesInDir;

Ok, after the information that your Activity extends ListActivity here's a way to implement OnItemClickListener:

public class newListView extends ListView {

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

    @Override
    public void setOnItemClickListener(
            android.widget.AdapterView.OnItemClickListener listener) {
        super.setOnItemClickListener(listener);
        //do something when item is clicked

    }

}

You just need the lines of code as below:

   try {
        String myjsonString = "{\"phonetype\":\"N95\",\"cat\":\"WP\"}";
        JSONObject jsonObject = new JSONObject(myjsonString );
        //displaying the JSONObject as a String
        Log.d("JSONObject = ", jsonObject.toString());
        //getting specific key values
        Log.d("phonetype = ", jsonObject.getString("phonetype"));
        Log.d("cat = ", jsonObject.getString("cat");
    }catch (Exception ex) {
         StringWriter stringWriter = new StringWriter();
         ex.printStackTrace(new PrintWriter(stringWriter));
         Log.e("exception ::: ", stringwriter.toString());
    }

Well, OpenSSL should do it handily from a #12 file:

openssl pkcs12 -in pkcs-12-certificate-file -out pem-certificate-file
openssl pkcs12 -in pkcs-12-certificate-and-key-file -out pem-certificate-and-key-file

Maybe more details on what the error/failure is?

The problem

I literally quote Saeed Neamati (https://stackoverflow.com/a/6587434/760777):

In your request header, you have sent Content-Type: text/html which means that you'd like to interpret the response as HTML. Now if even server send you PDF files, your browser tries to understand it as HTML.

The solution

Send the bloody correct header. Send the correct mime type of the file. Period!

How?

Aaah. That totally depends on what you are doing (OS, language).

My problem was with a dynamically created download link in javascript. The link is for downloading an mp3 file. An mp3 file is not a document, neither is a pdf, a zip file, a flac file and the list goes on.

So I created the link like this:

<form method="get" action="test.mp3"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

and I changed it to this:

<form method="get" action="test.mp3" enctype="multipart/form-data"> 
  <a href="#" onclick="this.closest(form).submit();return false;" target="_blank">
    <span class="material-icons">
      download
    </span>
  </a>
</form>

Problem solved. Adding an extra attribute to the form tag solved it. But there is no generic solution. There are many different scenario's. When you send a file from the server (you created it dynamically with a language like CX#, Java, PHP), you have to send the correct header(s) with it.

Side note: And be careful not to send anything (text!) before you send your header(s).

Actually, in Python 3 the module imp is marked as DEPRECATED. Well, at least that's true for 3.4.

Instead the reload function from the importlib module should be used:

https://docs.python.org/3/library/importlib.html#importlib.reload

But be aware that this library had some API-changes with the last two minor versions.

You want the gcc-specific noinline attribute.

This function attribute prevents a function from being considered for inlining. If the function does not have side-effects, there are optimizations other than inlining that causes function calls to be optimized away, although the function call is live. To keep such calls from being optimized away, put asm ("");

Use it like this:

void __attribute__ ((noinline)) foo() 
{
  ...
}

Not a regexp expert, but I think you could use a negative lookahead from the start, e.g. ^(?!foo).*$ shouldn't match anything starting with foo.

I usually used to make a function:

function getMonth(monthStr){
    return new Date(monthStr+'-1-01').getMonth()+1
}

And call it like :

getMonth('Jan');
getMonth('Feb');
getMonth('Dec');

how about like this

function isint(str){
    if(str.match(/\d/g).length==str.length){
        return true;
    }
    else {
         return false
    }
}

Java automatically interns String literals. This means that in many cases, the == operator appears to work for Strings in the same way that it does for ints or other primitive values.

Since interning is automatic for String literals, the intern() method is to be used on Strings constructed with new String()

Using your example:

String s1 = "Rakesh";
String s2 = "Rakesh";
String s3 = "Rakesh".intern();
String s4 = new String("Rakesh");
String s5 = new String("Rakesh").intern();

if ( s1 == s2 ){
    System.out.println("s1 and s2 are same");  // 1.
}

if ( s1 == s3 ){
    System.out.println("s1 and s3 are same" );  // 2.
}

if ( s1 == s4 ){
    System.out.println("s1 and s4 are same" );  // 3.
}

if ( s1 == s5 ){
    System.out.println("s1 and s5 are same" );  // 4.
}

will return:

s1 and s2 are same
s1 and s3 are same
s1 and s5 are same

In all the cases besides of s4 variable, a value for which was explicitly created using new operator and where intern method was not used on it's result, it is a single immutable instance that's being returned JVM's string constant pool.

Refer to JavaTechniques "String Equality and Interning" for more information.

ls -db di*/subdir | xargs -n 1 cp File

-b in case there is a space in directory name otherwise it will be broken as a different item by xargs, had this problem with the echo version

As of Swift 2.2, there is a special syntax for compiler-time checked selectors. It uses the syntax: #selector(methodName).

Swift 3 and later:

var b = UIBarButtonItem(
    title: "Continue",
    style: .plain,
    target: self,
    action: #selector(sayHello(sender:))
)

func sayHello(sender: UIBarButtonItem) {
}

If you are unsure what the method name should look like, there is a special version of the copy command that is very helpful. Put your cursor somewhere in the base method name (e.g. sayHello) and press Shift+Control+Option+C. That puts the ‘Symbol Name’ on your keyboard to be pasted. If you also hold Command it will copy the ‘Qualified Symbol Name’ which will include the type as well.

Swift 2.3:

var b = UIBarButtonItem(
    title: "Continue",
    style: .Plain,
    target: self,
    action: #selector(sayHello(_:))
)

func sayHello(sender: UIBarButtonItem) {
}

This is because the first parameter name is not required in Swift 2.3 when making a method call.

You can learn more about the syntax on swift.org here: https://swift.org/blog/swift-2-2-new-features/#compile-time-checked-selectors

Copying a string can be done two ways either copy the location a = "a" b = a or you can clone which means b wont get affected when a is changed which is done by a = 'a' b = a[:]

Both Redirect::to() and Redirect::away() should work.

Difference

Redirect::to() does additional URL checks and generations. Those additional steps are done in Illuminate\Routing\UrlGenerator and do the following, if the passed URL is not a fully valid URL (even with protocol):

Determines if URL is secure
rawurlencode() the URL
trim() URL

Thank you for the suggested solutions! Unfortunately, none of them worked for my case: receiving a list of CLOB objects from Oracle database through JPA - Hibernate, using a native query.

All of the proposed approaches gave me either a ClassCastException or just returned java Proxy object (which deeply inside contained the desired Clob).

So my solution is the following (based on several above approaches):

Query sqlQuery = manager.createNativeQuery(queryStr);
List resultList = sqlQuery.getResultList();
for ( Object resultProxy : resultList ) {
    String unproxiedClob = unproxyClob(resultProxy);
    if ( unproxiedClob != null ) {
       resultCollection.add(unproxiedClob);
    }
}

private String unproxyClob(Object proxy) {
    try {
        BeanInfo beanInfo = Introspector.getBeanInfo(proxy.getClass());
        for (PropertyDescriptor property : beanInfo.getPropertyDescriptors()) {
            Method readMethod = property.getReadMethod();
            if ( readMethod.getName().contains("getWrappedClob") ) {
                Object result = readMethod.invoke(proxy);
                return clobToString((Clob) result);
            }
        }
    }
    catch (InvocationTargetException | IntrospectionException | IllegalAccessException | SQLException | IOException e) {
        LOG.error("Unable to unproxy CLOB value.", e);
    }
    return null;
}

private String clobToString(Clob data) throws SQLException, IOException {
    StringBuilder sb = new StringBuilder();
    Reader reader = data.getCharacterStream();
    BufferedReader br = new BufferedReader(reader);

    String line;
    while( null != (line = br.readLine()) ) {
        sb.append(line);
    }
    br.close();

    return sb.toString();
}

Hope this will help somebody!

Use a list instead and replace your foreach loop with a for loop:

@model IList<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()

    @for (var i = 0; i < Model.Count; i++) 
    {
        <tr>
            <td>
                @Html.HiddenFor(x => x[i].IP)           
                @Html.CheckBoxFor(x => x[i].Checked)
            </td>
            <td>
                @Html.DisplayFor(x => x[i].IP)
            </td>
        </tr>
    }
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

Alternatively you could use an editor template:

@model IEnumerable<BlockedIPViewModel>

@using (Html.BeginForm()) 
{ 
    @Html.AntiForgeryToken()
    @Html.EditorForModel()   
    <div>
        <input type="submit" value="Unblock IPs" />
    </div>
}

and then define the template ~/Views/Shared/EditorTemplates/BlockedIPViewModel.cshtml which will automatically be rendered for each element of the collection:

@model BlockedIPViewModel
<tr>
    <td>
        @Html.HiddenFor(x => x.IP)
        @Html.CheckBoxFor(x => x.Checked)
    </td>
    <td>
        @Html.DisplayFor(x => x.IP)
    </td>
</tr>

The reason you were getting null in your controller is because you didn't respect the naming convention for your input fields that the default model binder expects to successfully bind to a list. I invite you to read the following article.

Once you have read it, look at the generated HTML (and more specifically the names of the input fields) with my example and yours. Then compare and you will understand why yours doesn't work.

This will be the simplest version of the implementation of RecyclerView.

  private List<String> data;
  public CustomAdapter (List<String> data){
    this.data = data;
  }

  @Override
  public CustomAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View rowItem = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_view, parent, false);
    return new ViewHolder(rowItem);
  }

  @Override
  public void onBindViewHolder(CustomAdapter.ViewHolder holder, int position) {
    holder.textView.setText(this.data.get(position));
  }

  @Override
  public int getItemCount() {
    return this.data.size();
  }

  public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    private TextView textView;

    public ViewHolder(View view) {
      super(view);
      view.setOnClickListener(this);
      this.textView = view.findViewById(R.id.textview);
    }

    @Override
    public void onClick(View view) {
      Toast.makeText(view.getContext(), "position : " + getLayoutPosition() + " text : " + this.textView.getText(), Toast.LENGTH_SHORT).show();
    }
  }
}

MainActivity.java

public class MainActivity extends AppCompatActivity {

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    RecyclerView recyclerView = findViewById(R.id.recycler_view);
    
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    recyclerView.setAdapter(new CustomAdapter(generateData()));
    recyclerView.addItemDecoration(new DividerItemDecoration(this, DividerItemDecoration.VERTICAL));
  }

  private List<String> generateData() {
    List<String> data = new ArrayList<>();
    for (int i = 0; i < 100; i++) {
      data.add(String.valueOf(i) + "th Element");
    }
    return data;
  }

}

There is a minlength property in the HTML5 specification now, as well as the validity.tooShort interface.

Both are now enabled in recent versions of all modern browsers. For details, see https://caniuse.com/#search=minlength.

I liked user4101525's answer best in theory but it doesn't actually work. Selection is not an overlay so you see whatever is under the control

Ramgy Borja's answer doesn't deal with the fact that default style is not actually a color at all so applying it doesn't help. This handles the default style and works if applying your own colors (which may be what edhubbell refers to as nasty results)

dgv.RowsDefaultCellStyle.SelectionBackColor = dgv.RowsDefaultCellStyle.BackColor.IsEmpty ? System.Drawing.Color.White : dgv.RowsDefaultCellStyle.BackColor;
dgv.RowsDefaultCellStyle.SelectionForeColor = dgv.RowsDefaultCellStyle.ForeColor.IsEmpty ? System.Drawing.Color.Black : dgv.RowsDefaultCellStyle.ForeColor;

From the documentation of __init__:

As a special constraint on constructors, no value may be returned; doing so will cause a TypeError to be raised at runtime.

As a proof, this code:

class Foo(object):
    def __init__(self):
        return 2

f = Foo()

Gives this error:

Traceback (most recent call last):
  File "test_init.py", line 5, in <module>
    f = Foo()
TypeError: __init__() should return None, not 'int'

You can use this

unset($dataArray['key']);

You can utilize the dependency management mechanism.

If you create entries in the <dependencyManagement> section of your pom for spring-security-web and spring-web with the desired 3.1.0 version set the managed version of the artifact will override those specified in the transitive dependency tree.

I'm not sure if that really saves you any code, but it is a cleaner solution IMO.

This should work :

str = str.replace(/[^a-z0-9-]/g, '');

Everything between the indicates what your are looking for

1. / is here to delimit your pattern so you have one to start and one to end
2. [] indicates the pattern your are looking for on one specific character
3. ^ indicates that you want every character NOT corresponding to what follows
4. a-z matches any character between 'a' and 'z' included
5. 0-9 matches any digit between '0' and '9' included (meaning any digit)
6. - the '-' character
7. g at the end is a special parameter saying that you do not want you regex to stop on the first character matching your pattern but to continue on the whole string

Then your expression is delimited by / before and after. So here you say "every character not being a letter, a digit or a '-' will be removed from the string".

not really the answer to the VIM problem but you could use the command line to also enter the commit message:

git commit -m "This is the first commit"

<?php
function info($name="George",$age=18) {
echo "$name is $age years old.<br>";
}
info();     // prints default values(number of values = 2)
info("Nick");   // changes first default argument from George to Nick
info("Mark",17);    // changes both default arguments' values

?>

On XFCE, go to Applications -> Settings -> Settings editor - > xfwm4 -> easy_click(disable value)

Now you can Insert Cursor with Alt + Click

I've also disabled L/R Workspace (ctrl + alt + L/R) settings in Settings -> Window manager -> Keyboard

I Get the same message, when using Intel XHAM emulator (instead of ARM) and have "Use Host GPU" option enabled. I belive when you disable it, it goes away.

No software & No too much steps..

Just upload your APK & get your all resources from this site..

https://www.apkdecompilers.com/

This website will decompile the code embedded in APK files and extract all the other assets in the file.

note: I decompile my APK file & get code within one miniute from this website

Update 1:

I found another online decompiler site,

http://www.javadecompilers.com/apk/ - Not working continuously asking for popup blocking

Update 2:

I found apk decompiler app in play store,

https://play.google.com/store/apps/details?id=com.njlabs.showjava

We can decompile the apk files in our android phone. and also we can able to view the java & xml files in this application

Update 3:

We can use another option Analyze APK feature from Android studio 2.2 version

Build -> Analyze APK -> Select your APK -> it give results

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.waist2height); {
        final EditText edit = (EditText)findViewById(R.id.editText);          
        final RadioButton rb1 = (RadioButton) findViewById(R.id.radioCM);
        final RadioButton rb2 = (RadioButton) findViewById(R.id.radioFT);                       
        if(rb1.isChecked()){    
            edit.setVisibility(View.VISIBLE);              
        }
        else if(rb2.isChecked()){               
            edit.setVisibility(View.INVISIBLE);
        }
}

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

This is an older question, but I found it yesterday while struggling with getting the MySQL Connector reference working properly on examples I'd found on the web. I'm working with VS 2010 on Win7 64 bit but have to work with .NET 3.5.

As others have stated, you need to download the .Net & Mono versions (I don't know why this is true, but it's what I've found works). The link to the connectors is given above in the earlier answers.

• Extract the connectors somewhere convenient.
• Open the project in Visual Studio, then on the menu bar navigate to Solution Explorer (View > Solution Explorer), and choose Properties (first box on the far left of the toolbar. The Solution Explorer shows up in the top right pane for me, but YMMV).
• In Properties, select References & locate the instance for mysql.data. It's likely to have a yellow bang on it (Yellow triangle with exclamation point in it). Remove it.
• Then on the menu bar, navigate to Project > Add Reference... > Browse > point to where you downloaded the connectors. I have only been able to get the V2 version to work, but that may be a factor of my platform, not sure.
• Clean & build your application. You should now be able to use the MySQL connectors to talk to your database.
• You can also now downgrade your .NET instance if you need to (we're constrained to .NET 3.5, but mysql.data.dll wants 4.0 at the time of my writing this). On the menu bar, navigate to the properties of your project (Project > Properties). Choose the Application tab > Target framework > Choose which .NET framework you want to use. You have to build the application at least once before you can change the .NET framework. Once you built once the connector will no longer complain about the lower version of .NET.

Check your node version node -v and your npm version npm -v Then To update your npm, type this into your terminal: npm install npm@latest -g

There is a very good fast food place analogy that best explains the event driven model of Node.js, see the full article, Node.js, Doctor’s Offices and Fast Food Restaurants – Understanding Event-driven Programming

Here is a summary:

If the fast food joint followed a traditional thread-based model, you'd order your food and wait in line until you received it. The person behind you wouldn't be able to order until your order was done. In an event-driven model, you order your food and then get out of line to wait. Everyone else is then free to order.

Node.js is event-driven, but most web servers are thread-based.York explains how Node.js works:

• You use your web browser to make a request for "/about.html" on a Node.js web server.

• The Node.js server accepts your request and calls a function to retrieve that file from disk.

• While the Node.js server is waiting for the file to be retrieved, it services the next web request.

• When the file is retrieved, there is a callback function that is inserted in the Node.js servers queue.

• The Node.js server executes that function which in this case would render the "/about.html" page and send it back to your web browser."

I find that when I can't conceptually grasp something, thinking about why one would use X is helpful to understand X. (Not to say you haven't tried that, I'm just setting the stage.)

[stuff you know]A common way to classify algorithms is by runtime, and by citing the big-Oh complexity of an algorithm, you can get a pretty good estimation of which one is "better" -- whichever has the "smallest" function in the O! Even in the real world, O(N) is "better" than O(N²), barring silly things like super-massive constants and the like.[/stuff you know]

Let's say there's some algorithm that runs in O(N). Pretty good, huh? But let's say you (you brilliant person, you) come up with an algorithm that runs in O(^N⁄_{loglogloglogN}). YAY! Its faster! But you'd feel silly writing that over and over again when you're writing your thesis. So you write it once, and you can say "In this paper, I have proven that algorithm X, previously computable in time O(N), is in fact computable in o(n)."

Thus, everyone knows that your algorithm is faster --- by how much is unclear, but they know its faster. Theoretically. :)

I have faced the same issue when I tried to install xampp on windows 8.1. The problem in my system was there was no password for the current logged in user account. After creating the password then I tried to install xampp. It installed without any issue. Hope it helps someone in the feature.

They're generally stored on the server. Where they're stored is up to you as the developer. You can use the session.save_handler configuration variable and the session_set_save_handler to control how sessions get saved on the server. The default save method is to save sessions to files. Where they get saved is controlled by the session.save_path variable.

I like Roko's answer, and added a few lines to it so that you get a triangle that points right when the element is hidden, and down when it is displayed:

.collapse { font-weight: bold; display: inline-block; }
.collapse + input:after { content: " \25b6"; display: inline-block; }
.collapse + input:checked:after { content: " \25bc"; display: inline-block; }
.collapse + input { display: inline-block; -webkit-appearance: none; -o-appearance:none; -moz-appearance:none;  }
.collapse + input + * { display: none; }
.collapse + input:checked + * { display: block; }

Generated Column is one of the good approach for MySql version which is 5.7.6 and above.

There are two kinds of Generated Columns:

• Virtual (default) - column will be calculated on the fly when a record is read from a table
• Stored - column will be calculated when a new record is written/updated in the table

Both types can have NOT NULL restrictions, but only a stored Generated Column can be a part of an index.

For current case, we are going to use stored generated column. To implement I have considered that both of the values required for calculation are present in table

CREATE TABLE order_details (price DOUBLE, quantity INT, amount DOUBLE AS (price * quantity));

INSERT INTO order_details (price, quantity) VALUES(100,1),(300,4),(60,8);

amount will automatically pop up in table and you can access it directly, also please note that whenever you will update any of the columns, amount will also get updated.

This is the best way to do it, very simple.

$msg = "Hello this is a string";
$first_index_of_i = stripos($msg,'i');
$last_index_of_i = strripos($msg, 'i');

echo "First i : " . $first_index_of_i . PHP_EOL ."Last i : " . $last_index_of_i;

It's working (mysql) :

SELECT TABLE_NAME , count(COLUMN_NAME)
FROM information_schema.columns
GROUP BY TABLE_NAME 

string outString= number.ToString("####0.00");

I concur with the other answers. UUIDs are safe enough for nearly all practical purposes¹, and certainly for yours.

But suppose (hypothetically) that they aren't.

Is there a better system or a pattern of some type to alleviate this issue?

Here are a couple of approaches:

1. Use a bigger UUID. For instance, instead of a 128 random bits, use 256 or 512 or ... Each bit you add to a type-4 style UUID will reduce the probability of a collision by a half, assuming that you have a reliable source of entropy².

2. Build a centralized or distributed service that generates UUIDs and records each and every one it has ever issued. Each time it generates a new one, it checks that the UUID has never been issued before. Such a service would be technically straight-forward to implement (I think) if we assumed that the people running the service were absolutely trustworthy, incorruptible, etcetera. Unfortunately, they aren't ... especially when there is the possibility of governments' security organizations interfering. So, this approach is probably impractical, and may be³ impossible in the real world.

^{1 - If uniqueness of UUIDs determined whether nuclear missiles got launched at your country's capital city, a lot of your fellow citizens would not be convinced by "the probability is extremely low". Hence my "nearly all" qualification.}

^{2 - And here's a philosophical question for you. Is anything ever truly random? How would we know if it wasn't? Is the universe as we know it a simulation? Is there a God who might conceivably "tweak" the laws of physics to alter an outcome?}

^{3 - If anyone knows of any research papers on this problem, please comment.}

I had to put some the displayed javascripts above inside the "document.ready" code. Otherwise they didn't work. Probably obvious for many, but not for me. So if you're testing look at that option.

<script type="text/javascript">
$(document).ready(function(){
//rest of the javascript code here
});
</script>

Here is another helpful solution for manually adding custom HTTP Headers to your client WCF request using the ChannelFactory as a proxy. This would have to be done for each request, but suffices as a simple demo if you just need to unit test your proxy in preparation for non-.NET platforms.

// create channel factory / proxy ...
using (OperationContextScope scope = new OperationContextScope(proxy))
{
    OperationContext.Current.OutgoingMessageProperties[HttpRequestMessageProperty.Name] = new HttpRequestMessageProperty()
    {
        Headers = 
        { 
            { "MyCustomHeader", Environment.UserName },
            { HttpRequestHeader.UserAgent, "My Custom Agent"}
        }
    };    
    // perform proxy operations... 
}
