There are two options here.

1. a hidden field within the form, or
2. Add it to the route values parameter in the begin form method.

Edit

@Html.Hidden("clubid", ViewBag.Club.id)

or

 @using(Html.BeginForm("action", "controller",
                       new { clubid = @Viewbag.Club.id }, FormMethod.Post, null)

I have just written an app which can make a call from a web page - I don't know if this is any use to you, but I include anyway:

in your onCreate you'll need to use a webview and assign a WebViewClient, as below:

browser = (WebView) findViewById(R.id.webkit);
browser.setWebViewClient(new InternalWebViewClient());

then handle the click on a phone number like this:

private class InternalWebViewClient extends WebViewClient {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
         if (url.indexOf("tel:") > -1) {
            startActivity(new Intent(Intent.ACTION_DIAL, Uri.parse(url)));
            return true;
        } else {
            return false;
        }
    }
}

Let me know if you need more pointers.

Here is another try:

function stringToColor(str){
  var hash = 0;
  for(var i=0; i < str.length; i++) {
    hash = str.charCodeAt(i) + ((hash << 3) - hash);
  }
  var color = Math.abs(hash).toString(16).substring(0, 6);

  return "#" + '000000'.substring(0, 6 - color.length) + color;
}

2. sudo easy_install requests==2.3.0
3. sudo apt-get install python-pip

Use Ctrl-N to get a list of word suggestions while in insert mode. Type :help i_CTRL-N to see Vim's documentation on this functionality.

Here is an example of importing the Python dictionary into Vim.

git checkout old_branch
git branch new_branch

This will give you a new branch "new_branch" with the same state as "old_branch".

This command can be combined to the following:

git checkout -b new_branch old_branch

I know that this question has been answered, And all the answers are nice. But I wanted to add my two cents to this question for people who have similar (but not exactly the same) problem.

In a more general way, we can do something like this:

$('body').click(function(evt){    
    if(!$(evt.target).is('#menu_content')) {
        //event handling code
    }
});

This way we can handle not only events fired by anything except element with id menu_content but also events that are fired by anything except any element that we can select using CSS selectors.

For instance in the following code snippet I am getting events fired by any element except all <li> elements which are descendants of div element with id myNavbar.

$('body').click(function(evt){    
    if(!$(evt.target).is('div#myNavbar li')) {
        //event handling code
    }
});

Try the below JS

$(function() {
    $('#type').change(function(){
        $('#row_dim').hide(); 
        if ($(this).val() == 'parcel')
        {
             $('#row_dim').show();
        }
    });
});

I had the problem that my Eclipse was not debugging the source code of my project. I was getting a blank page with "Source code node found".

Please click the Attach source code button. Then delete the "default" folder then click add and go to your project location and attach. This worked for me

I'm guessing that your class is in a different namespace. The canonical way to solve this would be to use the resources class and a strongly typed resource:

ProjectNamespace.Properties.Resources.file

Use the IDE's resource manager to add resources.

The r makes the string a raw string, which doesn't process escape characters (however, since there are none in the string, it is actually not needed here).

Also, re.match matches from the beginning of the string. In other words, it looks for an exact match between the string and the pattern. To match stuff that could be anywhere in the string, use re.search. See a demonstration below:

>>> import re
>>> line = 'This,is,a,sample,string'
>>> re.match("sample", line)
>>> re.search("sample", line)
<_sre.SRE_Match object at 0x021D32C0>
>>>

I got this error because I tried to rename a sheet with too many characters

I had the same problem and after some searching I was able to find my logs at the following location:

C:\Users\<yourid>\.AndroidStudioPreview\system\log

I was looking to find the answer to this question too, but the accepted answer was breaking for me. Apparently using window.innerWidth isn't portable. It does work in some browsers, but I noticed Firefox didn't like it.

Gregg Tavares posted a great resource here that addresses this issue directly: http://webglfundamentals.org/webgl/lessons/webgl-anti-patterns.html (See anti-pattern #'s 3 and 4).

Using canvas.clientWidth instead of window.innerWidth seems to work nicely.

Here's Gregg's suggested render loop:

function resize() {
  var width = gl.canvas.clientWidth;
  var height = gl.canvas.clientHeight;
  if (gl.canvas.width != width ||
      gl.canvas.height != height) {
     gl.canvas.width = width;
     gl.canvas.height = height;
     return true;
  }
  return false;
}

var needToRender = true;  // draw at least once
function checkRender() {
   if (resize() || needToRender) {
     needToRender = false;
     drawStuff();
   }
   requestAnimationFrame(checkRender);
}
checkRender();

Java 8 solution

We can use lambda expression or method reference introduced in Java 8. In case we have some String values stored in the Priority Queue (having capacity 5) we can provide inline comparator (based on length of String) :

Using lambda expression

PriorityQueue<String> pq=
                    new PriorityQueue<String>(5,(a,b) -> a.length() - b.length());

Using Method reference

PriorityQueue<String> pq=
                new PriorityQueue<String>(5, Comparator.comparing(String::length));

Then we can use any of them as:

public static void main(String[] args) {
        PriorityQueue<String> pq=
                new PriorityQueue<String>(5, (a,b) -> a.length() - b.length());
       // or pq = new PriorityQueue<String>(5, Comparator.comparing(String::length));
        pq.add("Apple");
        pq.add("PineApple");
        pq.add("Custard Apple");
        while (pq.size() != 0)
        {
            System.out.println(pq.remove());
        }
    }

This will print:

Apple
PineApple
Custard Apple

To reverse the order (to change it to max-priority queue) simply change the order in inline comparator or use reversed as:

PriorityQueue<String> pq = new PriorityQueue<String>(5, 
                             Comparator.comparing(String::length).reversed());

We can also use Collections.reverseOrder:

PriorityQueue<Integer> pqInt = new PriorityQueue<>(10, Collections.reverseOrder());
PriorityQueue<String> pq = new PriorityQueue<String>(5, 
                Collections.reverseOrder(Comparator.comparing(String::length))

So we can see that Collections.reverseOrder is overloaded to take comparator which can be useful for custom objects. The reversed actually uses Collections.reverseOrder:

default Comparator<T> reversed() {
    return Collections.reverseOrder(this);
}

offer() vs add()

As per the doc

The offer method inserts an element if possible, otherwise returning false. This differs from the Collection.add method, which can fail to add an element only by throwing an unchecked exception. The offer method is designed for use when failure is a normal, rather than exceptional occurrence, for example, in fixed-capacity (or "bounded") queues.

When using a capacity-restricted queue, offer() is generally preferable to add(), which can fail to insert an element only by throwing an exception. And PriorityQueue is an unbounded priority queue based on a priority heap.

I had the same problem and found a very elegant solution for a Pager Class from

http://blogs.taiga.nl/martijn/2008/08/27/paging-with-aspnet-mvc/

In your controller the call looks like:

return View(partnerList.ToPagedList(currentPageIndex, pageSize));

and in your view:

<div class="pager">
    Seite: <%= Html.Pager(ViewData.Model.PageSize, 
                          ViewData.Model.PageNumber,
                          ViewData.Model.TotalItemCount)%>
</div>

You should re-assign the result of the replacement, like this:

 sentence = sentence.replace("and", " ");

Be aware that the String class is immutable, meaning that all of its methods return a new string and never modify the original string in-place, so the result of invoking a method in an instance of String must be assigned to a variable or used immediately for the change to take effect.

You can try the following code to request camera permission in marshmallow. First check if the user grant the permission. If user has not granted the permission, then request the camera permission:

private static final int MY_CAMERA_REQUEST_CODE = 100;

if (checkSelfPermission(Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
    requestPermissions(new String[]{Manifest.permission.CAMERA}, MY_CAMERA_REQUEST_CODE);
}

After requesting the permission, dialog will display to ask permission containing allow and deny options. After clicking action we can get result of the request with the following method:

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == MY_CAMERA_REQUEST_CODE) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
        } else {
            Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
        }
    }
}

This error occurs because VMware has a bug that uses the absolute path of the disk file in certain situations.

If you look at the top of that small *.vmdk file you'll likely see an incorrect absolute path to the original VMDK file that needs to be corrected.

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

</script>

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

TimezoneDb provides a free API: http://timezonedb.com/api

GenoNames also has a RESTful API available to get the current time for a given location: http://www.geonames.org/export/ws-overview.html.

You can use Greenwich, UK if you'd like GMT.

You could also consider the possibility of storing the password outside the script, and supplying it at runtime

e.g. fred.py

import os
username = 'fred'
password = os.environ.get('PASSWORD', '')
print(username, password)

which can be run like

$ PASSWORD=password123 python fred.py
fred password123

Extra layers of "security through obscurity" can be achieved by using base64 (as suggested above), using less obvious names in the code and further distancing the actual password from the code.

If the code is in a repository, it is often useful to store secrets outside it, so one could add this to ~/.bashrc (or to a vault, or a launch script, ...)

export SURNAME=cGFzc3dvcmQxMjM=

and change fred.py to

import os
import base64
name = 'fred'
surname = base64.b64decode(os.environ.get('SURNAME', '')).decode('utf-8')
print(name, surname)

then re-login and

$ python fred.py
fred password123

You can use

Dispatcher.Invoke(Delegate, object[])

on the Application's (or any UIElement's) dispatcher.

You can use it for example like this:

Application.Current.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));

or

someControl.Dispatcher.Invoke(new Action(() => { /* Your code here */ }));

We got it working by copying the routes from Router.php instead of using Auth::routes(), these are the routes you need:

Route::get('login', 'Auth\LoginController@showLoginForm')->name('login');
Route::post('login', 'Auth\LoginController@login');
Route::post('logout', 'Auth\LoginController@logout')->name('logout');

// Registration Routes...
Route::get('register', 'Auth\RegisterController@showRegistrationForm')->name('register');
Route::post('register', 'Auth\RegisterController@register');

// Password Reset Routes...
Route::get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
Route::post('password/email', 'Auth\ForgotPasswordController@sendResetLinkEmail')->name('password.email');
Route::get('password/reset/{token}', 'Auth\ResetPasswordController@showResetForm')->name('password.reset');
Route::post('password/reset', 'Auth\ResetPasswordController@reset');

For me the simple solution works to set cookies in HttpRequestMessage object.

protected async Task<HttpResponseMessage> SendRequest(HttpRequestMessage requestMessage, CancellationToken cancellationToken = default(CancellationToken))
{
    requestMessage.Headers.Add("Cookie", $"<Cookie Name 1>=<Cookie Value 1>;<Cookie Name 2>=<Cookie Value 2>");

    return await _httpClient.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false);
}

I also experienced the same thing. I found out that my favicon.ico had not been processed as a legitimate shortcut icon. I understand that favicons must be scaled to 16x16 and follow the Microsoft Icon format.

And for completeness, Mac OS X

import AppKit
[(screen.frame().size.width, screen.frame().size.height)
    for screen in AppKit.NSScreen.screens()]

will give you a list of tuples containing all screen sizes (if multiple monitors present)

I had the same problem.

system configuration:-single system with window 7 sp1 server and client both are installed on same system

I was trying to access the window desktop. As some the answer say that your Sqlserver service don't have full access to the directory. This is totally right.

I solved this problem by doing a few simple steps

1. Go to All Programs->microsoft sql server 2008 -> configuration tools and then select sql server configuration manager.
2. Select the service and go to properties. In the build in Account dialog box select local system and then select ok button.

Steps 3 and 4 in image are demo with accessing the folder

A quick and dirty way of estimating the mode of a vector of numbers you believe come from a continous univariate distribution (e.g. a normal distribution) is defining and using the following function:

estimate_mode <- function(x) {
  d <- density(x)
  d$x[which.max(d$y)]
}

Then to get the mode estimate:

x <- c(5.8, 5.6, 6.2, 4.1, 4.9, 2.4, 3.9, 1.8, 5.7, 3.2)
estimate_mode(x)

try to disable the rewrite module in ubuntu using sudo a2dismod rewrite. This will perhaps stop your apache server to crash.

The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format

<TextBox Text="{Binding Value,  StringFormat={}{0:#,0.0}}" 

$(this).dialog('destroy');

works!

Try this:

<!DOCTYPE html>
<html>
<head>
    <style type="text/css">
    p {
        text-align: right;
    }
    input {
        width: 100px;
    }
    </style>
</head>

<body>
    <form>
        <p>
            <input name="declared_first" value="above" />
        </p>
        <p>
            <input name="declared_second" value="below" />
        </p>
    </form>
</body>
</html>

I got a similar problem , I parsed the youtube url. The code is;

$json_is = "http://gdata.youtube.com/feeds/api/videos?q=".$this->video_url."&max-results=1&alt=json";
$video_info = json_decode ( file_get_contents ( $json_is ), true );     
$video_title = is_array ( $video_info ) ? $video_info ['feed'] ['entry'] [0] ['title'] ['$t'] : '';

Then I realise that $this->video_url include the whitespace. I solved that using trim($this->video_url).

Maybe it will help you . Good Luck

Here is my solution, inspired from Beta's answer. It's simpler than the other proposed solutions

I have a project with several C files, stored in many subdirectories. For example:

src/lib.c
src/aa/a1.c
src/aa/a2.c
src/bb/b1.c
src/cc/c1.c

Here is my Makefile (in the src/ directory):

# make       -> compile the shared library "libfoo.so"
# make clean -> remove the library file and all object files (.o)
# make all   -> clean and compile
SONAME  = libfoo.so
SRC     = lib.c   \
          aa/a1.c \
          aa/a2.c \
          bb/b1.c \
          cc/c1.c
# compilation options
CFLAGS  = -O2 -g -W -Wall -Wno-unused-parameter -Wbad-function-cast -fPIC
# linking options
LDFLAGS = -shared -Wl,-soname,$(SONAME)

# how to compile individual object files
OBJS    = $(SRC:.c=.o)
.c.o:
    $(CC) $(CFLAGS) -c $< -o $@

.PHONY: all clean

# library compilation
$(SONAME): $(OBJS) $(SRC)
    $(CC) $(OBJS) $(LDFLAGS) -o $(SONAME)

# cleaning rule
clean:
    rm -f $(OBJS) $(SONAME) *~

# additional rule
all: clean lib

This example works fine for a shared library, and it should be very easy to adapt for any compilation process.

@robertc has it right, but you also need to notice that svg, #container causes the svg to be scaled exponentially for anything but 100% (once for #container and once for svg).

In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.

One selector works fine when used as @robertc suggests.

svg {
  width:50%;
  height:50%;
}

Add the following aliases. I think these should be made available in PowerShell by default:

function not-exist { -not (Test-Path $args) }
Set-Alias !exist not-exist -Option "Constant, AllScope"
Set-Alias exist Test-Path -Option "Constant, AllScope"

With that, the conditional statements will change to:

if (exist $path) { ... }

and

if (not-exist $path) { ... }
if (!exist $path) { ... }

I would like to improve weston's and Roger Huang's answers for over API 21 Android lollipop with theme "Theme.AppCompat".

Below Android 4.4

<resources>
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    </style>

   <!-- Application theme. -->
   <style name="AppTheme" parent="AppBaseTheme">
       <item name="android:typeface">monospace</item>
   </style>
</resources>

Over(equal) API 5.0

<resources>
    <style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    </style>

   <!-- Application theme. -->
   <style name="AppTheme" parent="AppBaseTheme">
       <item name="android:textAppearance">@style/CustomTextAppearance</item>
   </style>

   <style name="CustomTextAppearance">
       <item name="android:typeface">monospace</item>
   </style>
</resources>

And the FontsOverride util file is same as what in weston's answer. I have tested in these phones:

Nexus 5(android 5.1 Primary Android System)

ZTE V5(android 5.1 CM12.1)

XIAOMI note(android 4.4 MIUI6)

HUAWEI C8850(android 2.3.5 UNKNOWN)

As stated in MSDN (eg. https://msdn.microsoft.com/en-us/library/system.diagnostics.eventlog(v=vs.110).aspx ), checking an non existing source and creating a source requires admin privilege.

It is however possible to use the source "Application" without. In my test under Windows 2012 Server r2, I however get the following log entry using "Application" source:

The description for Event ID xxxx from source Application cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: {my event entry message} the message resource is present but the message is not found in the string/message table

I defined the following method to create the source:

    private string CreateEventSource(string currentAppName)
    {
        string eventSource = currentAppName;
        bool sourceExists;
        try
        {
            // searching the source throws a security exception ONLY if not exists!
            sourceExists = EventLog.SourceExists(eventSource);
            if (!sourceExists)
            {   // no exception until yet means the user as admin privilege
                EventLog.CreateEventSource(eventSource, "Application");
            }
        }
        catch (SecurityException)
        {
            eventSource = "Application";
        }

        return eventSource;
    }

I am calling it with currentAppName = AppDomain.CurrentDomain.FriendlyName

It might be possible to use the EventLogPermission class instead of this try/catch but not sure we can avoid the catch.

It is also possible to create the source externally, e.g in elevated Powershell:

New-EventLog -LogName Application -Source MyApp

Then, using 'MyApp' in the method above will NOT generate exception and the EventLog can be created with that source.

Slightly more condensed than gbn's:

Assuming CourseId is non-zero

CAST (COALESCE(FC.CourseId, 0) AS Bit)

COALESCE is like an ISNULL(), but returns the first non-Null.

A Non-Zero CourseId will get type-cast to a 1, while a null CourseId will cause COALESCE to return the next value, 0

Exists = IsObject(CurrentDb.TableDefs(tablename))

Use the builtin function zip():

In Python 3:

z = list(zip(x,y))

In Python 2:

z = zip(x,y)

The only thing I would add to these amazing answers is to emphasize on saving your files in utf8 encoding, i have noticed that browsers accept this property over setting utf8 as your code encoding. Any decent text editor will show you this, for example Notepad++ has a menu option for file enconding, it shows you the current encoding and enables you to change it. For all my php files I use utf8 without BOM.

Sometime ago i had someone ask me to add utf8 support for a php/mysql application designed by someone else, i noticed that all files were encoded in ANSI, so I had to use ICONV to convert all files, change the database tables to use the utf8 charset and utf8_general_ci collate, add 'SET NAMES utf8' to the database abstraction layer after the connection (if using 5.3.6 or earlier otherwise you have to use charset=utf8 in the connection string) and change string functions to use the php multibyte string functions equivalent.

I have also met this issue and wasted a lot of time debugging it.

First, make sure that the path you provide is valid, i.e., there is an image in that path.

Next, you should be aware that Opencv doesn't support image paths which contain unicode characters (see ref). If your image path contains Unicode characters, you can use the following code to read the image:

import numpy as np
import cv2

# img is in BGR format if the underlying image is a color image
img = cv2.imdecode(np.fromfile(im_path, dtype=np.uint8), cv2.IMREAD_UNCHANGED)

If you want to make your code work as above, the function printInformation() needs to be declared and implemented as a static function.

If, on the other hand, it is supposed to print information about a specific object, you need to create the object first.

To remove the tracked and old committed file from git you can use the below command. Here in my case, I want to untrack and remove all the file from dist directory.

git filter-branch --force --index-filter 'git rm -r --cached --ignore-unmatch dist' --tag-name-filter cat -- --all

Then, you need to add it into your .gitignore so it won't be tracked further.

The [:-1] removes the last element. Instead of

a[3:-1]

write

a[3:]

You can read up on Python slicing notation here: Explain Python's slice notation

NumPy slicing is an extension of that. The NumPy tutorial has some coverage: Indexing, Slicing and Iterating.

Clear mini-solution $('<form action="http://samedomainurl.com/" target="_blank"></form>').submit()

MySQL use HAVING statement for this tasks.

Your query would look like this:

SELECT g.group_id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m USING(group_id)
GROUP BY g.group_id
HAVING members > 4

example when references have different names

SELECT g.id, COUNT(m.member_id) AS members
FROM groups AS g
LEFT JOIN group_members AS m ON g.id = m.group_id
GROUP BY g.id
HAVING members > 4

Also, make sure that you set indexes inside your database schema for keys you are using in JOINS as it can affect your site performance.

I find it is most useful to use Runnable for all the reasons mentioned, but sometimes I like to extend Thread so I can create my own thread stopping method and call it directly on the thread I have created.

in Javascript.

    var myObject = { "name" : "john" };
    // { "name" : "john" };
    myObject.gender = "male";
    // { "name" : "john", "gender":"male"};

If you prefer method call notation, you can force a left join using SelectMany combined with DefaultIfEmpty. At least on Entity Framework 6 hitting SQL Server. For example:

using(var ctx = new MyDatabaseContext())
{
    var data = ctx
    .MyTable1
    .SelectMany(a => ctx.MyTable2
      .Where(b => b.Id2 == a.Id1)
      .DefaultIfEmpty()
      .Select(b => new
      {
        a.Id1,
        a.Col1,
        Col2 = b == null ? (int?) null : b.Col2,
      }));
}

(Note that MyTable2.Col2 is a column of type int). The generated SQL will look like this:

I was facing the same problem when I was trying to connect Mysql to a Remote Server. I had found out that I had to change the bind-address to the current private IP address of the DB server. But when I was trying to add the bind-address =0.0.0.0 line in my.cnf file, it was not understanding the line when I tried to create a DB.

Upon searching, I found out the original place where bind-address was declared.

The actual declaration is in : /etc/mysql/mariadb.conf.d/50-server.cnf

Therefore I changed the bind-address directly there and then all seems working.

If you don't specify the platform for the app you won't able to add app domain correctly.

Here is an example -- validate that its a type a website platform.

If you DELETE the branch after merging it, just be aware that all hyperlinks, URLs, and references of your DELETED branch will be BROKEN.

Empty Collection. If you're using C#, the assumption is that maximizing system resources is not essential. While less efficient, returning Empty Collection is much more convenient for the programmers involved (for the reason Will outlined above).

I follow the Python Idioms and Efficiency guidelines, by Rob Knight. I think they are exactly the same as PEP 8, but are more synthetic and based on examples.

If you are using wxPython you might also want to check Style Guide for wxPython code, by Chris Barker, as well.

It's the array that's causing trouble in:

void print_graph(g_node graph_node[], double weight[][], int nodes);

The second and subsequent dimensions must be given:

void print_graph(g_node graph_node[], double weight[][32], int nodes);

Or you can just give a pointer to pointer:

void print_graph(g_node graph_node[], double **weight, int nodes);

However, although they look similar, those are very different internally.

If you're using C99, you can use variably-qualified arrays. Quoting an example from the C99 standard (section §6.7.5.2 Array Declarators):

void fvla(int m, int C[m][m]); // valid: VLA with prototype scope

void fvla(int m, int C[m][m])  // valid: adjusted to auto pointer to VLA
{
    typedef int VLA[m][m];     // valid: block scope typedef VLA
    struct tag {
        int (*y)[n];           // invalid: y not ordinary identifier
        int z[n];              // invalid: z not ordinary identifier
    };
    int D[m];                  // valid: auto VLA
    static int E[m];           // invalid: static block scope VLA
    extern int F[m];           // invalid: F has linkage and is VLA
    int (*s)[m];               // valid: auto pointer to VLA
    extern int (*r)[m];        // invalid: r has linkage and points to VLA
    static int (*q)[m] = &B;   // valid: q is a static block pointer to VLA
}

Question in comments

[...] In my main(), the variable I am trying to pass into the function is a double array[][], so how would I pass that into the function? Passing array[0][0] into it gives me incompatible argument type, as does &array and &array[0][0].

In your main(), the variable should be:

double array[10][20];

or something faintly similar; maybe

double array[][20] = { { 1.0, 0.0, ... }, ... };

You should be able to pass that with code like this:

typedef struct graph_node
{
    int X;
    int Y;
    int active;
} g_node;

void print_graph(g_node graph_node[], double weight[][20], int nodes);

int main(void)
{
    g_node g[10];
    double array[10][20];
    int n = 10;

    print_graph(g, array, n);
    return 0;
}

That compiles (to object code) cleanly with GCC 4.2 (i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.9.00)) and also with GCC 4.7.0 on Mac OS X 10.7.3 using the command line:

/usr/bin/gcc -O3 -g -std=c99 -Wall -Wextra -c zzz.c

Note: This solution only works for Mac and *nix users.

I also tried to find Jad with no luck. My quick solution was to download MacJad that contains jad. Once you downloaded it you can find jad in [where-you-downloaded-macjad]/MacJAD/Contents/Resources/jad.

You need to use [[, the programmatic equivalent of $. Otherwise, for example, when i is col1, R will look for df$i instead of df$col1.

for(i in names(df)){
  df[[paste(i, 'length', sep="_")]] <- str_length(df[[i]])
}

If you give the code a .c extension the compiler thinks it is C code, not C++. And the C++ compiler driver is called g++, if you use the gcc driver you will have linker problems, as the standard C++ libraries will not be linked by default. So you want:

g++ myprog.cpp

And do not even consider using an uppercase .C extension, unless you never want to port your code, and are prepared to be hated by those you work with.

I would advise you to use pylibmc instead.

It can act as a drop-in replacement of python-memcache, but a lot faster(as it's written in C). And you can find handy documentation for it here.

And to the question, as pylibmc just acts as a drop-in replacement, you can still refer to documentations of pylibmc for your python-memcache programming.

IMHO this question is an evergreen. As stated in various answers, the assignment of an unsigned value that is not in the range [0,INT_MAX] is implementation defined and might even raise a signal. If the unsigned value is considered to be a two's complement representation of a signed number, the probably most portable way is IMHO the way shown in the following code snippet:

#include <limits.h>
unsigned int u;
int i;

if (u <= (unsigned int)INT_MAX)
  i = (int)u; /*(1)*/
else if (u >= (unsigned int)INT_MIN)
  i = -(int)~u - 1; /*(2)*/
else
  i = INT_MIN; /*(3)*/

• Branch (1) is obvious and cannot invoke overflow or traps, since it is value-preserving.

• Branch (2) goes through some pains to avoid signed integer overflow by taking the one's complement of the value by bit-wise NOT, casts it to 'int' (which cannot overflow now), negates the value and subtracts one, which can also not overflow here.

• Branch (3) provides the poison we have to take on one's complement or sign/magnitude targets, because the signed integer representation range is smaller than the two's complement representation range.

This is likely to boil down to a simple move on a two's complement target; at least I've observed such with GCC and CLANG. Also branch (3) is unreachable on such a target -- if one wants to limit the execution to two's complement targets, the code could be condensed to

#include <limits.h>
unsigned int u;
int i;

if (u <= (unsigned int)INT_MAX)
  i = (int)u; /*(1)*/
else
  i = -(int)~u - 1; /*(2)*/

The recipe works with any signed/unsigned type pair, and the code is best put into a macro or inline function so the compiler/optimizer can sort it out. (In which case rewriting the recipe with a ternary operator is helpful. But it's less readable and therefore not a good way to explain the strategy.)

And yes, some of the casts to 'unsigned int' are redundant, but

• they might help the casual reader

• some compilers issue warnings on signed/unsigned compares, because the implicit cast causes some non-intuitive behavior by language design

I remember my CompSci professor saying never to use floats for currency.

The reason for that is how the IEEE specification defines floats in binary format. Basically, it stores sign, fraction and exponent to represent a Float. It's like a scientific notation for binary (something like +1.43*10^2). Because of that, it is impossible to store fractions and decimals in Float exactly.

That's why there is a Decimal format. If you do this:

irb:001:0> "%.47f" % (1.0/10)
=> "0.10000000000000000555111512312578270211815834045" # not "0.1"!

whereas if you just do

irb:002:0> (1.0/10).to_s
=> "0.1" # the interprer rounds the number for you

So if you are dealing with small fractions, like compounding interests, or maybe even geolocation, I would highly recommend Decimal format, since in decimal format 1.0/10 is exactly 0.1.

However, it should be noted that despite being less accurate, floats are processed faster. Here's a benchmark:

require "benchmark" 
require "bigdecimal" 

d = BigDecimal.new(3) 
f = Float(3)

time_decimal = Benchmark.measure{ (1..10000000).each { |i| d * d } } 
time_float = Benchmark.measure{ (1..10000000).each { |i| f * f } }

puts time_decimal 
#=> 6.770960 seconds 
puts time_float 
#=> 0.988070 seconds

Answer

Use float when you don't care about precision too much. For example, some scientific simulations and calculations only need up to 3 or 4 significant digits. This is useful in trading off accuracy for speed. Since they don't need precision as much as speed, they would use float.

Use decimal if you are dealing with numbers that need to be precise and sum up to correct number (like compounding interests and money-related things). Remember: if you need precision, then you should always use decimal.

From the HERE and HERE

public File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

public static File getExternalStorageDirectory ()

Return the primary external storage directory. This directory may not currently be accessible if it has been mounted by the user on their computer, has been removed from the device, or some other problem has happened. You can determine its current state with getExternalStorageState().

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.

If you want to get your application path use getFilesDir() which will give you path /data/data/your package/files

You can get the path using the Environment var of your data/package using the

getExternalFilesDir(Environment.getDataDirectory().getAbsolutePath()).getAbsolutePath(); which will return the path from the root directory of your external storage as /storage/sdcard/Android/data/your pacakge/files/data

To access the external resources you have to provide the permission of WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE in your manifest.

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

Since c is holding the address of an integer pointer, its type should be int**:

int **c;
c = &a;

The entire program becomes:

#include <stdio.h>                                                              
int main(){
    int b=10;
    int *a;
    a=&b;
    int **c;
    c=&a;
    printf("%d",(**c));   //successfully prints 10
    return 0;
}

I think the most elegant solution is to pass a lambda function to "type", as mentioned by Chepner. In addition to this, if you do not know beforehand what the delimiter of your list will be, you can also pass multiple delimiters to re.split:

# python3 test.py -l "abc xyz, 123"

import re
import argparse

parser = argparse.ArgumentParser(description='Process a list.')
parser.add_argument('-l', '--list',
                    type=lambda s: re.split(' |, ', s),
                    required=True,
                    help='comma or space delimited list of characters')

args = parser.parse_args()
print(args.list)


# Output: ['abc', 'xyz', '123']

As the official document: As of 1.9, a string is only considered to be HTML if it starts with a less-than ("<") character. The Migrate plugin can be used to restore the pre-1.9 behavior.

If a string is known to be HTML but may start with arbitrary text that is not an HTML tag, pass it to jQuery.parseHTML() which will return an array of DOM nodes representing the markup. A jQuery collection can be created from this, for example: $($.parseHTML(htmlString)). This would be considered best practice when processing HTML templates for example. Simple uses of literal strings such as $("<p>Testing</p>").appendTo("body") are unaffected by this change.

__main__.py is used for python programs in zip files. The __main__.py file will be executed when the zip file in run. For example, if the zip file was as such:

test.zip
     __main__.py

and the contents of __main__.py was

import sys
print "hello %s" % sys.argv[1]

Then if we were to run python test.zip world we would get hello world out.

So the __main__.py file run when python is called on a zip file.

i suggest to give a width to all the grid's columns like this :

DataGridViewTextBoxColumn col = new DataGridViewTextBoxColumn();
col.HeaderText = "phone"            
col.Width = 120;
col.DataPropertyName = (if you use a datasource)
thegrid.Columns.Add(col);    

and for the main(or the longest) column(let's say address) do this :

col = new DataGridViewTextBoxColumn();
col.HeaderText = "address";
col.Width = 120;

tricky part

col.MinimumWidth = 120;
col.AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

tricky part

col.DataPropertyName = (same as above)
thegrid.Columns.Add(col);

In this way, if you stretch the form (and the grid is "dock filled" in his container) the main column, in this case the address column, takes all the space available, but it never goes less than col.MinimumWidth, so it's the only one that is resized.

I use it, when i have a grid and its last column is used for display an image (like icon detail or icon delete..) and it doesn't have the header and it has to be always the smallest one.

Would it not make sense to use msbuild directly? If you are doing this with every build, then you can add a msbuild task at the end? If you would just like to see if you can’t find another macro value that is not showed on the Visual Studio IDE, you could switch on the msbuild options to diagnostic and that will show you all of the variables that you could use, as well as their current value.

To switch this on in visual studio, go to Tools/Options then scroll down the tree view to the section called Projects and Solutions, expand that and click on Build and Run, at the right their is a drop down that specify the build output verbosity, setting that to diagnostic, will show you what other macro values you could use.

Because I don’t quite know to what level you would like to go, and how complex you want your build to be, this might give you some idea. I have recently been doing build scripts, that even execute SQL code as part of the build. If you would like some more help or even some sample build scripts, let me know, but if it is just a small process you want to run at the end of the build, the perhaps going the full msbuild script is a bit of over kill.

I used 'live' in my project but one of my friend suggested that i should use 'on' instead of live. And when i tried to use that i experienced a problem like you had.

On my pages i create buttons table rows and many dom stuff dynamically. but when i use on the magic disappeared.

The other solutions like use it like a child just calls your functions every time on every click. But i find a way to make it happen again and here is the solution.

Write your code as:

function caller(){
    $('.ObjectYouWntToCall').on("click", function() {...magic...});
}

Call caller(); after you create your object in the page like this.

$('<dom class="ObjectYouWntToCall">bla... bla...<dom>').appendTo("#whereeveryouwant");
caller();

By this way your function is called when it is supposed to not every click on the page.

The error means that you have data in other tables that references the data you are trying to delete.

You would need to either drop and recreate the constraints or delete the data that the Foreign Key references.

Suppose you have the following tables

dbo.Students
(
StudentId
StudentName
StudentTypeId
)


dbo.StudentTypes
(
StudentTypeId
StudentType
)

Suppose a Foreign Key constraint exists between the StudentTypeId column in StudentTypes and the StudentTypeId column in Students

If you try to delete all the data in StudentTypes an error will occur as the StudentTypeId column in Students reference the data in the StudentTypes table.

EDIT:

DELETE and TRUNCATE essentially do the same thing. The only difference is that TRUNCATE does not save the changes in to the Log file. Also you can't use a WHERE clause with TRUNCATE

AS to why you can run this in SSMS but not via your Application. I really can't see this happening. The FK constraint would still throw an error regardless of where the transaction originated from.

chaining is always best :D

C++11 update to a very old question: Print variable type in C++.

The accepted (and good) answer is to use typeid(a).name(), where a is a variable name.

Now in C++11 we have decltype(x), which can turn an expression into a type. And decltype() comes with its own set of very interesting rules. For example decltype(a) and decltype((a)) will generally be different types (and for good and understandable reasons once those reasons are exposed).

Will our trusty typeid(a).name() help us explore this brave new world?

No.

But the tool that will is not that complicated. And it is that tool which I am using as an answer to this question. I will compare and contrast this new tool to typeid(a).name(). And this new tool is actually built on top of typeid(a).name().

The fundamental issue:

typeid(a).name()

throws away cv-qualifiers, references, and lvalue/rvalue-ness. For example:

const int ci = 0;
std::cout << typeid(ci).name() << '\n';

For me outputs:

i

and I'm guessing on MSVC outputs:

int

I.e. the const is gone. This is not a QOI (Quality Of Implementation) issue. The standard mandates this behavior.

What I'm recommending below is:

template <typename T> std::string type_name();

which would be used like this:

const int ci = 0;
std::cout << type_name<decltype(ci)>() << '\n';

and for me outputs:

int const

<disclaimer> I have not tested this on MSVC. </disclaimer> But I welcome feedback from those who do.

The C++11 Solution

I am using __cxa_demangle for non-MSVC platforms as recommend by ipapadop in his answer to demangle types. But on MSVC I'm trusting typeid to demangle names (untested). And this core is wrapped around some simple testing that detects, restores and reports cv-qualifiers and references to the input type.

#include <type_traits>
#include <typeinfo>
#ifndef _MSC_VER
#   include <cxxabi.h>
#endif
#include <memory>
#include <string>
#include <cstdlib>

template <class T>
std::string
type_name()
{
    typedef typename std::remove_reference<T>::type TR;
    std::unique_ptr<char, void(*)(void*)> own
           (
#ifndef _MSC_VER
                abi::__cxa_demangle(typeid(TR).name(), nullptr,
                                           nullptr, nullptr),
#else
                nullptr,
#endif
                std::free
           );
    std::string r = own != nullptr ? own.get() : typeid(TR).name();
    if (std::is_const<TR>::value)
        r += " const";
    if (std::is_volatile<TR>::value)
        r += " volatile";
    if (std::is_lvalue_reference<T>::value)
        r += "&";
    else if (std::is_rvalue_reference<T>::value)
        r += "&&";
    return r;
}

The Results

With this solution I can do this:

int& foo_lref();
int&& foo_rref();
int foo_value();

int
main()
{
    int i = 0;
    const int ci = 0;
    std::cout << "decltype(i) is " << type_name<decltype(i)>() << '\n';
    std::cout << "decltype((i)) is " << type_name<decltype((i))>() << '\n';
    std::cout << "decltype(ci) is " << type_name<decltype(ci)>() << '\n';
    std::cout << "decltype((ci)) is " << type_name<decltype((ci))>() << '\n';
    std::cout << "decltype(static_cast<int&>(i)) is " << type_name<decltype(static_cast<int&>(i))>() << '\n';
    std::cout << "decltype(static_cast<int&&>(i)) is " << type_name<decltype(static_cast<int&&>(i))>() << '\n';
    std::cout << "decltype(static_cast<int>(i)) is " << type_name<decltype(static_cast<int>(i))>() << '\n';
    std::cout << "decltype(foo_lref()) is " << type_name<decltype(foo_lref())>() << '\n';
    std::cout << "decltype(foo_rref()) is " << type_name<decltype(foo_rref())>() << '\n';
    std::cout << "decltype(foo_value()) is " << type_name<decltype(foo_value())>() << '\n';
}

and the output is:

decltype(i) is int
decltype((i)) is int&
decltype(ci) is int const
decltype((ci)) is int const&
decltype(static_cast<int&>(i)) is int&
decltype(static_cast<int&&>(i)) is int&&
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int&
decltype(foo_rref()) is int&&
decltype(foo_value()) is int

Note (for example) the difference between decltype(i) and decltype((i)). The former is the type of the declaration of i. The latter is the "type" of the expression i. (expressions never have reference type, but as a convention decltype represents lvalue expressions with lvalue references).

Thus this tool is an excellent vehicle just to learn about decltype, in addition to exploring and debugging your own code.

In contrast, if I were to build this just on typeid(a).name(), without adding back lost cv-qualifiers or references, the output would be:

decltype(i) is int
decltype((i)) is int
decltype(ci) is int
decltype((ci)) is int
decltype(static_cast<int&>(i)) is int
decltype(static_cast<int&&>(i)) is int
decltype(static_cast<int>(i)) is int
decltype(foo_lref()) is int
decltype(foo_rref()) is int
decltype(foo_value()) is int

I.e. Every reference and cv-qualifier is stripped off.

C++14 Update

Just when you think you've got a solution to a problem nailed, someone always comes out of nowhere and shows you a much better way. :-)

This answer from Jamboree shows how to get the type name in C++14 at compile time. It is a brilliant solution for a couple reasons:

1. It's at compile time!
2. You get the compiler itself to do the job instead of a library (even a std::lib). This means more accurate results for the latest language features (like lambdas).

Jamboree's answer doesn't quite lay everything out for VS, and I'm tweaking his code a little bit. But since this answer gets a lot of views, take some time to go over there and upvote his answer, without which, this update would never have happened.

This code will auto-backoff on the constexpr if you're still stuck in ancient C++11. And if you're painting on the cave wall with C++98/03, the noexcept is sacrificed as well.

I've updated the constants for VS thanks to the very nice detective work by Jive Dadson in the comments below.

Update:

Be sure to check out this rewrite below which eliminates the unreadable magic numbers in my latest formulation.

One more thing you could try:

• Check if you have pending Windows updates.
• If you do, please reboot before trying anything else.

I tend to never shut down my machine, so I had plenty of them waiting for a reboot. And that fixed it.

The order in which ng-click and ng-model will be executed is ambiguous (since neither explicitly set their priority). The most stable solution to this would be to avoid using them on the same element.

Also, you probably do not want the behavior that the examples show; you want the checkbox to respond to clicks on the complete label text, not only the checkbox. Hence, the cleanest solution would be to wrap the input (with ng-model) inside a label (with ng-click):

<label ng-click="onCompleteTodo(todo)">
  <input type='checkbox' ng-model="todo.done">
  {{todo.text}}
</label>

Working example: http://jsfiddle.net/b3NLH/1/

I hit this error calling:

dict(my_data)

I fixed this with:

import json

json.loads(my_data)

Above accepted answer is not browser compatible. If some one has compatibility issue try this.

Fiddle

View Code

 <div ng-controller="MyCtrl">
      <input type="file" id="file" name="file"/>
      <br>
      <button ng-click="add()">Add</button>
      <p>{{data}}</p>
    </div>

Controller code

var myApp = angular.module('myApp',[]);

function MyCtrl($scope) {
    $scope.data = 'none';    
    $scope.add = function(){
      var f = document.getElementById('file').files[0],
          r = new FileReader();
      r.onloadend = function(e){        
          var binary = "";
var bytes = new Uint8Array(e.target.result);
var length = bytes.byteLength;

for (var i = 0; i < length; i++) 
{
    binary += String.fromCharCode(bytes[i]);
}

$scope.data = (binary).toString();

          alert($scope.data);
      }
      r.readAsArrayBuffer(f);
    }
}

Consider using an instance of ExecutorService. Both invokeAll() and invokeAny() methods are available with a timeout parameter.

The current thread will block until the method completes (not sure if this is desirable) either because the task(s) completed normally or the timeout was reached. You can inspect the returned Future(s) to determine what happened.

Using the standard mysql.createPool(), connections are lazily created by the pool. If you configure the pool to allow up to 100 connections, but only ever use 5 simultaneously, only 5 connections will be made. However if you configure it for 500 connections and use all 500 they will remain open for the durations of the process, even if they are idle!

This means if your MySQL Server max_connections is 510 your system will only have 10 mySQL connections available until your MySQL Server closes them (depends on what you have set your wait_timeout to) or your application closes! The only way to free them up is to manually close the connections via the pool instance or close the pool.

mysql-connection-pool-manager module was created to fix this issue and automatically scale the number of connections dependant on the load. Inactive connections are closed and idle connection pools are eventually closed if there has not been any activity.

    // Load modules
const PoolManager = require('mysql-connection-pool-manager');

// Options
const options = {
  ...example settings
}

// Initialising the instance
const mySQL = PoolManager(options);

// Accessing mySQL directly
var connection = mySQL.raw.createConnection({
  host     : 'localhost',
  user     : 'me',
  password : 'secret',
  database : 'my_db'
});

// Initialising connection
connection.connect();

// Performing query
connection.query('SELECT 1 + 1 AS solution', function (error, results, fields) {
  if (error) throw error;
  console.log('The solution is: ', results[0].solution);
});

// Ending connection
connection.end();

For some applications you can use Fraction instead of floating-point numbers.

>>> from fractions import Fraction
>>> Fraction(1, 3**54)
Fraction(1, 58149737003040059690390169)

(For other applications, there's decimal, as suggested out by the other responses.)

I just solved this issue on HackerRank, so I'm here to share my result

function timeConversion(s) {
    const isPM = s.indexOf('PM') !== -1;
    let [hours, minutes, seconds] = s.replace(isPM ? 'PM':'AM', '').split(':');

    if (isPM) {
        hours = parseInt(hours, 10) + 12;
        hours = hours === 24 ? 12 : hours;
    } else {
        hours = parseInt(hours, 10);
        hours = hours === 12 ? 0 : hours;
        if (String(hours).length === 1) hours = '0' + hours;
    }

    const time = [hours, minutes, seconds].join(':');

    return time;
}

This works for inputs like 06:40:03AM.

I don't think "blueprint" is a good word to use. A blueprint tells you how to build something. An interface specifically avoids telling you how to build something.

An interface defines how you can interact with a class, i.e. what methods it supports.

For anyone willing to try a different method, they can use this:

select FORMAT([Column_Name], '') from YourTable

This will easily change any float value to nvarchar.

Here is how you set the date and time:

update user set expiry_date=TO_DATE('31/DEC/2017 12:59:59', 'dd/mm/yyyy hh24:mi:ss') where id=123;

first create folder by command line mkdir C:\data\db (This is for database) then run command mongod --port 27018 by one command prompt(administration mode)- you can give name port number as your wish

With ES6: This is now part of the language:

function myFunc(a, b = 0) {
   // function body
}

Please keep in mind that ES6 checks the values against undefined and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).

With ES5:

function myFunc(a,b) {
  b = b || 0;

  // b will be set either to b or to 0.
}

This works as long as all values you explicitly pass in are truthy. Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''

It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.

http uses port 80, and understandably, your internet browser will automatically use that port when you type in an address - unless you specify another port. Now, when running a web server on your computer, you need to access that server somehow - and since port 80 is already busy, you need to use a different port to successfully connect to it. Although any open port is fair game, usually such a server is configured to use port 8080, hence when accessing your server you type in:

http:// (protocol) localhost (your computer) :8080 (port 8080) / (path pointing to the root of the public folder of your server)

To avoid accidentally overwriting an existing file use:

using (new FileStream(filename, FileMode.CreateNew)) {}

...and handle the IOException which will occur if the file already exists.

File.Create, which is suggested in other answers, will overwrite the contents of the file if it already exists. In simple cases you could mitigate this using File.Exists(). However something more robust is necessary in scenarios where multiple threads and/or processes are attempting to create files in the same folder simultaneously.

Short answer: There's no way to do it using CSS only.

Long(er) answer: Why? Because when you do position: absolute;, that takes your element out of the document's regular flow, so there's no way for the text to have any positional-relationship with it, unfortunately.

One of the possible alternatives is to float: right; your div, but if that doesn't achieve what you want, you'll have to use JavaScript/jQuery, or just come up with a better layout.

You can try giving position: fixed; top: 0; bottom: 0; properties to your container.

What a great misunderstanding between events and delegates!!! A delegate specifies a TYPE (such as a class, or an interface does), whereas an event is just a kind of MEMBER (such as fields, properties, etc). And, just like any other kind of member an event also has a type. Yet, in the case of an event, the type of the event must be specified by a delegate. For instance, you CANNOT declare an event of a type defined by an interface.

Concluding, we can make the following Observation: the type of an event MUST be defined by a delegate. This is the main relation between an event and a delegate and is described in the section II.18 Defining events of ECMA-335 (CLI) Partitions I to VI:

In typical usage, the TypeSpec (if present) identifies a delegate whose signature matches the arguments passed to the event’s fire method.

However, this fact does NOT imply that an event uses a backing delegate field. In truth, an event may use a backing field of any different data structure type of your choice. If you implement an event explicitly in C#, you are free to choose the way you store the event handlers (note that event handlers are instances of the type of the event, which in turn is mandatorily a delegate type---from the previous Observation). But, you can store those event handlers (which are delegate instances) in a data structure such as a List or a Dictionary or any other else, or even in a backing delegate field. But don’t forget that it is NOT mandatory that you use a delegate field.

InstanceID.getInstance(getApplicationContext()).getToken(authorizedEntity,scope)

authorizedEntity is the project number of the server

DSCLAIMER This method has a critical flaw in that the partition is not anchored to the end of the url and may return spurious results. For example, the result for the URL "www.comcast.net" is "www" (incorrect) instead of the expected "www.comcast.net". This solution therefore is evil. Don't use it unless you know what you are doing!

url.rpartition('.com')[0]

This is fairly easy to type and also correctly returns the original string (no error) when the suffix '.com' is missing from url.

In WPF MVVM terms, a POCO class is one that does not Fire PropertyChanged events

This question, although rather old, needs some benchmarks, as it asks for not the most idiomatic way, or the way that can be written in the fewest number of lines, but the fastest way. And it is silly to answer that question without some actual testing. So I compared four solutions, memset vs. std::fill vs. ZERO of AnT's answer vs a solution I made using AVX intrinsics.

Note that this solution is not generic, it only works on data of 32 or 64 bits. Please comment if this code is doing something incorrect.

#include<immintrin.h>
#define intrin_ZERO(a,n){\
size_t x = 0;\
const size_t inc = 32 / sizeof(*(a));/*size of 256 bit register over size of variable*/\
for (;x < n-inc;x+=inc)\
    _mm256_storeu_ps((float *)((a)+x),_mm256_setzero_ps());\
if(4 == sizeof(*(a))){\
    switch(n-x){\
    case 3:\
        (a)[x] = 0;x++;\
    case 2:\
        _mm_storeu_ps((float *)((a)+x),_mm_setzero_ps());break;\
    case 1:\
        (a)[x] = 0;\
        break;\
    case 0:\
        break;\
    };\
}\
else if(8 == sizeof(*(a))){\
switch(n-x){\
    case 7:\
        (a)[x] = 0;x++;\
    case 6:\
        (a)[x] = 0;x++;\
    case 5:\
        (a)[x] = 0;x++;\
    case 4:\
        _mm_storeu_ps((float *)((a)+x),_mm_setzero_ps());break;\
    case 3:\
        (a)[x] = 0;x++;\
    case 2:\
        ((long long *)(a))[x] = 0;break;\
    case 1:\
        (a)[x] = 0;\
        break;\
    case 0:\
        break;\
};\
}\
}

I will not claim that this is the fastest method, since I am not a low level optimization expert. Rather it is an example of a correct architecture dependent implementation that is faster than memset.

Now, onto the results. I calculated performance for size 100 int and long long arrays, both statically and dynamically allocated, but with the exception of msvc, which did a dead code elimination on static arrays, the results were extremely comparable, so I will show only dynamic array performance. Time markings are ms for 1 million iterations, using time.h's low precision clock function.

fill:        613
ZERO:        221
intrin_ZERO: 95
long long:

intrin_ZERO: 188

There is a lot interesting going on here: llvm killing gcc, MSVC's typical spotty optimizations (it does an impressive dead code elimination on static arrays and then has awful performance for fill). Although my implementation is significantly faster, this may only be because it recognizes that bit clearing has much less overhead than any other setting operation.

Clang's implementation merits more looking at, as it is significantly faster. Some additional testing shows that its memset is in fact specialized for zero--non zero memsets for 400 byte array are much slower (~220ms) and are comparable to gcc's. However, the nonzero memsetting with an 800 byte array makes no speed difference, which is probably why in that case, their memset has worse performance than my implementation--the specialization is only for small arrays, and the cuttoff is right around 800 bytes. Also note that gcc 'fill' and 'ZERO' are not optimizing to memset (looking at generated code), gcc is simply generating code with identical performance characteristics.

Conclusion: memset is not really optimized for this task as well as people would pretend it is (otherwise gcc and msvc and llvm's memset would have the same performance). If performance matters then memset should not be a final solution, especially for these awkward medium sized arrays, because it is not specialized for bit clearing, and it is not hand optimized any better than the compiler can do on its own.

I suspect something is not right when you are saving to the db. Do i understand your steps as:

1. populate and bind
2. user selects and item, hit and save.. then you save in the db
3. now if you select another item it won't select?

got more code, especially when saving? where in your code are initializing and populating the bindinglist

You can get the concatenated year and week number (200945) using the YEARWEEK() function. If I understand your goal correctly, that should enable you to group your multi-year data.

If you need the actual timestamp for the start of the week, it's less nice:

DATE_SUB( field, INTERVAL DAYOFWEEK( field ) - 1 DAY )

For monthly ordering, you might consider the LAST_DAY() function - sort would be by last day of the month, but that should be equivalent to sorting by first day of the month ... shouldn't it?

I wrote up one-line bash script that would delete ALL your simulators:

xcrun simctl list devices | grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})" | xargs -L1 xcrun simctl delete

• xcrun simctl list devices will list all the simulators installed on your machine
• grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})" will grab the device UUID
• xargs -L1 xcrun simctl delete will attempt to delete the device for each UUID it found

If you want to see everything it'll execute, you can add echo before xcrun, i.e.

xcrun simctl list devices | grep -E -o -i "([0-9a-f]{8}-([0-9a-f]{4}-){3}[0-9a-f]{12})" | xargs -L1 echo xcrun simctl delete

Check out perlfaq4: How do I merge two hashes. There is a lot of good information already in the Perl documentation and you can have it right away rather than waiting for someone else to answer it. :)

Before you decide to merge two hashes, you have to decide what to do if both hashes contain keys that are the same and if you want to leave the original hashes as they were.

If you want to preserve the original hashes, copy one hash (%hash1) to a new hash (%new_hash), then add the keys from the other hash (%hash2 to the new hash. Checking that the key already exists in %new_hash gives you a chance to decide what to do with the duplicates:

my %new_hash = %hash1; # make a copy; leave %hash1 alone

foreach my $key2 ( keys %hash2 )
    {
    if( exists $new_hash{$key2} )
        {
        warn "Key [$key2] is in both hashes!";
        # handle the duplicate (perhaps only warning)
        ...
        next;
        }
    else
        {
        $new_hash{$key2} = $hash2{$key2};
        }
    }

If you don't want to create a new hash, you can still use this looping technique; just change the %new_hash to %hash1.

foreach my $key2 ( keys %hash2 )
    {
    if( exists $hash1{$key2} )
        {
        warn "Key [$key2] is in both hashes!";
        # handle the duplicate (perhaps only warning)
        ...
        next;
        }
    else
        {
        $hash1{$key2} = $hash2{$key2};
        }
    }

If you don't care that one hash overwrites keys and values from the other, you could just use a hash slice to add one hash to another. In this case, values from %hash2 replace values from %hash1 when they have keys in common:

@hash1{ keys %hash2 } = values %hash2;

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

Recently I needed to find width and height for setting default size of .dialog representing graph. Solution I use was :

 graph= $('<img/>', {"src":'mySRC', id:'graph-img'});
    graph.bind('load', function (){
        wid = graph.attr('width');
        hei = graph.attr('height');

        graph.dialog({ autoOpen: false, title: 'MyGraphTitle', height:hei, width:wid })
    })

For me this works in FF3, Opera 10, IE 8,7,6

P.S. You may be find some more solutions looking inside some plugins like LightBox or ColorBox

This method will give you : 2017-08-04T11:15:00.000+04:30 and you can ignore zone variable to simply get 2017-08-04T11:15:00.000.

function getLocalIsoDateTime(dtString) {
    if(dtString == "")
        return "";
    var offset = new Date().getTimezoneOffset();
    var localISOTime = (new Date(new Date(dtString) - offset * 60000 /*offset in milliseconds*/)).toISOString().slice(0,-1);
    //Next two lines can be removed if zone isn't needed.
    var absO = Math.abs(offset);
    var zone = (offset < 0 ? "+" : "-") + ("00" + Math.floor(absO / 60)).slice(-2) + ":" + ("00" + (absO % 60)).slice(-2);
    return localISOTime + zone;
}

Great level of solutions here.

My little grain of salt as the solution @Patrick Cuff did not work out of the box; I had 2 problems

• I use Windows 7 => changed to "skip=2"
• The value of the registry value had a space in it Value Value = C:\Program Files\...

Here is the solution I found: taking 4 tokens and setting ValueValue to %%C and %%D. (Thanks @Ivan!)

setlocal ENABLEEXTENSIONS
set KEY_NAME="HKEY_CURRENT_USER\Software\Microsoft\Command Processor"
set VALUE_NAME=DefaultColor

FOR /F "usebackq skip=2 tokens=1-4" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C %%D
)

if defined ValueName (
    @echo Value Name = %ValueName%
    @echo Value Type = %ValueType%
    @echo Value Value = %ValueValue%
) else (
    @echo "%KEY_NAME:"=%\%VALUE_NAME%" not found.
)

The question has already been answered, but I thought I'd add an answer with more precise terminology and references to the C++ standard.

Two things are going on here, array parameters being adjusted to pointer parameters, and array arguments being converted to pointer arguments. These are two quite different mechanisms, the first is an adjustment to the actual type of the parameter, whereas the other is a standard conversion which introduces a temporary pointer to the first element.

Adjustments to your function declaration:

dcl.fct#5:

After determining the type of each parameter, any parameter of type “array of T” (...) is adjusted to be “pointer to T”.

So int arg[] is adjusted to be int* arg.

Conversion of your function argument:

conv.array#1

An lvalue or rvalue of type “array of N T” or “array of unknown bound of T” can be converted to a prvalue of type “pointer to T”. The temporary materialization conversion is applied. The result is a pointer to the first element of the array.

So in printarray(firstarray, 3);, the lvalue firstarray of type "array of 3 int" is converted to a prvalue (temporary) of type "pointer to int", pointing to the first element.

Here is the contents of the configuration file I used to support both .NET 2.0 and .NET 4 assemblies:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <!-- http://msdn.microsoft.com/en-us/library/w4atty68.aspx -->
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0" />
    <supportedRuntime version="v2.0.50727" />
  </startup>
</configuration>

Also, here’s a simplified version of the PowerShell 1.0 compatible code I used to execute our scripts from the passed in command line arguments:

class Program {
  static void Main( string[] args ) {
    Console.WriteLine( ".NET " + Environment.Version );

    string script = "& " + string.Join( " ", args );
    Console.WriteLine( script );
    Console.WriteLine( );

    // Simple host that sends output to System.Console
    PSHost host = new ConsoleHost( this );
    Runspace runspace = RunspaceFactory.CreateRunspace( host );

    Pipeline pipeline = runspace.CreatePipeline( );
    pipeline.Commands.AddScript( script );

    try {
      runspace.Open( );
      IEnumerable<PSObject> output = pipeline.Invoke( );
      runspace.Close( );

      // ...
    }
    catch( RuntimeException ex ) {
      string psLine = ex.ErrorRecord.InvocationInfo.PositionMessage;
      Console.WriteLine( "error : {0}: {1}{2}", ex.GetType( ), ex.Message, psLine );
      ExitCode = -1;
    }
  }
}

In addition to the basic error handling shown above, we also inject a trap statement into the script to display additional diagnostic information (similar to Jeffrey Snover's Resolve-Error function).

Just add a css property:

<style>   
a {
 pointer-events: none;
}
</style>

Doing so you can disable the anchor tag.

Your code is correct. Kindly mark small correction.

For example I am using this technique in Basket functionality.

Let us add new Item to Basket.

var productArray=[];


$(document).on('click','[cartBtn]',function(e){
  e.preventDefault();
  $(this).html('<i class="fa fa-check"></i>Added to cart');
  console.log('Item added ');
  var productJSON={"id":$(this).attr('pr_id'), "nameEn":$(this).attr('pr_name_en'), "price":$(this).attr('pr_price'), "image":$(this).attr('pr_image'), "quantity":1, "discount":0, "total":$(this).attr('pr_price')};


  if(localStorage.getObj('product')!==null){
    productArray=localStorage.getObj('product');
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }
  else{
    productArray.push(productJSON);  
    localStorage.setObj('product', productArray);  
  }


  itemCountInCart(productArray.length);

});

After adding some item to basket - generates json array like this

[
    {
        "id": "95",
        "nameEn": "New Braslet",
        "price": "8776",
        "image": "1462012394815.jpeg",
        "quantity": 1,
        "discount": 0,
        "total": "8776"
    },
    {
        "id": "96",
        "nameEn": "new braslet",
        "price": "76",
        "image": "1462012431497.jpeg",
        "quantity": 1,
        "discount": 0,
        "total": "76"
    },
    {
        "id": "97",
        "nameEn": "khjk",
        "price": "87",
        "image": "1462012483421.jpeg",
        "quantity": 1,
        "discount": 0,
        "total": "87"
    }
]

For Removing some item from Basket.

$(document).on('click','[itemRemoveBtn]',function(){

var arrayFromLocal=localStorage.getObj('product');
findAndRemove(arrayFromLocal,"id",$(this).attr('basketproductid'));
localStorage.setObj('product', arrayFromLocal);
loadBasketFromLocalStorageAndRender();
});

//This function will remove element by specified property. In my case this is ID.
function findAndRemove(array, property, value) {
  array.forEach(function(result, index) {
    if(result[property] === value) {
      //Remove from array
      console.log('Removed from index is '+index+' result is '+JSON.stringify(result));
      array.splice(index, 1);

    }    
  });
}

And Finally the real answer of the question "Updating a JSON object using JS". In my example updating product quantity and total price on changing the "number" element value.

$(document).on('keyup mouseup','input[type=number]',function(){

  var arrayFromLocal=localStorage.getObj('product');
  setQuantityAndTotalPrice(arrayFromLocal,$(this).attr('updateItemid'),$(this).val());
  localStorage.setObj('product', arrayFromLocal);
  loadBasketFromLocalStorageAndRender();
});

function setQuantityAndTotalPrice(array,id,quantity) {

  array.forEach(function(result, index) {
    if(result.id === id) {
      result.quantity=quantity;
      result.total=(quantity*result.price);
    }    
  });

}

If you want to get number of physical cores you can run cmd and terminal command and then to parse the output to get info you need.Below is shown function that returns number of physical cores .

I got it working from one I made.

<?php

$src = imagecreatefromjpeg('cover2.jpg');

imagealphablending($dest, false);

This is what I found when I had this doubt.

mysql> create table numbers (a decimal(10,2), b float);
mysql> insert into numbers values (100, 100);
mysql> select @a := (a/3), @b := (b/3), @a * 3, @b * 3 from numbers \G
*************************** 1. row ***************************
  @a := (a/3): 33.333333333
  @b := (b/3): 33.333333333333
@a + @a + @a: 99.999999999000000000000000000000
@b + @b + @b: 100

The decimal did exactly what's supposed to do on this cases, it truncated the rest, thus losing the 1/3 part.

So for sums the decimal is better, but for divisions the float is better, up to some point, of course. I mean, using DECIMAL will not give you a "fail proof arithmetic" in any means.

Hope this helps.

Using spread operator (ES6)

Math.max(...array);  // the same with "min" => Math.min(...array);

const array = [10, 2, 33, 4, 5];_x000D_
_x000D_
console.log(_x000D_
  Math.max(...array)_x000D_
)

More universal can be: for each v Selection : v.value = "'" & v.value : next and selecting range of cells before execution

iPad Media Queries (All generations - including iPad mini)

Thanks to Apple's work in creating a consistent experience for users, and easy time for developers, all 5 different iPads (iPads 1-5 and iPad mini) can be targeted with just one CSS media query. The next few lines of code should work perfect for a responsive design.

iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)  { /* STYLES GO HERE */}

iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape) { /* STYLES GO HERE */}

iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait) { /* STYLES GO HERE */ }

iPad 3 & 4 Media Queries

If you're looking to target only 3rd and 4th generation Retina iPads (or tablets with similar resolution) to add @2x graphics, or other features for the tablet's Retina display, use the following media queries.

Retina iPad in portrait & landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in landscape

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : landscape)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */}

Retina iPad in portrait

@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) 
and (orientation : portrait)
and (-webkit-min-device-pixel-ratio: 2) { /* STYLES GO HERE */ }

iPad 1 & 2 Media Queries

If you're looking to supply different graphics or choose different typography for the lower resolution iPad display, the media queries below will work like a charm in your responsive design!

iPad 1 & 2 in portrait & landscape

@media only screen

A small drawback in Marc's answer is that both datefields have been typecast, meaning you'll be unable to leverage any indexes.

So, if there is a need to write a query that can benefit from an index on a date field, then the following (rather convoluted) approach is necessary.

• The indexed datefield (call it DF1) must be untouched by any kind of function.
• So you have to compare DF1 to the full range of datetime values for the day of DF2.
• That is from the date-part of DF2, to the date-part of the day after DF2.
• I.e. (DF1 >= CAST(DF2 AS DATE)) AND (DF1 < DATEADD(dd, 1, CAST(DF2 AS DATE)))
• NOTE: It is very important that the comparison is >= (equality allowed) to the date of DF2, and (strictly) < the day after DF2. Also the BETWEEN operator doesn't work because it permits equality on both sides.

PS: Another means of extracting the date only (in older versions of SQL Server) is to use a trick of how the date is represented internally.

• Cast the date as a float.
• Truncate the fractional part
• Cast the value back to a datetime
• I.e. CAST(FLOOR(CAST(DF2 AS FLOAT)) AS DATETIME)

Declare them before the while loop.

For a discussion on why to prefer comprehensions over higher-order functions such as map, go to http://www.artima.com/weblogs/viewpost.jsp?thread=98196.

Here's a pretty decent pattern.

For debugging: When an error is raised, hit Ctrl-Break (or Ctrl-Pause), drag the break marker (or whatever it's called) down to the Resume line, hit F8 and you'll step to the line that "threw" the error.

The ExitHandler is your "Finally".

Hourglass will be killed every time. Status bar text will be cleared every time.

Public Sub ErrorHandlerExample()
    Dim dbs As DAO.Database
    Dim rst As DAO.Recordset

    On Error GoTo ErrHandler
    Dim varRetVal As Variant

    Set dbs = CurrentDb
    Set rst = dbs.OpenRecordset("SomeTable", dbOpenDynaset, dbSeeChanges + dbFailOnError)

    Call DoCmd.Hourglass(True)

    'Do something with the RecordSet and close it.

    Call DoCmd.Hourglass(False)

ExitHandler:
    Set rst = Nothing
    Set dbs = Nothing
    Exit Sub

ErrHandler:
    Call DoCmd.Hourglass(False)
    Call DoCmd.SetWarnings(True)
    varRetVal = SysCmd(acSysCmdClearStatus)

    Dim errX As DAO.Error
    If Errors.Count > 1 Then
       For Each errX In DAO.Errors
          MsgBox "ODBC Error " & errX.Number & vbCrLf & errX.Description
       Next errX
    Else
        MsgBox "VBA Error " & Err.Number & ": " & vbCrLf & Err.Description & vbCrLf & "In: Form_MainForm", vbCritical
    End If

    Resume ExitHandler
    Resume

End Sub



    Select Case Err.Number
        Case 3326 'This Recordset is not updateable
            'Do something about it. Or not...
        Case Else
            MsgBox "VBA Error " & Err.Number & ": " & vbCrLf & Err.Description & vbCrLf & "In: Form_MainForm", vbCritical
    End Select

It also traps for both DAO and VBA errors. You can put a Select Case in the VBA error section if you want to trap for specific Err numbers.

Select Case Err.Number
    Case 3326 'This Recordset is not updateable
        'Do something about it. Or not...
    Case Else
        MsgBox "VBA Error " & Err.Number & ": " & vbCrLf & Err.Description & vbCrLf & "In: Form_MainForm", vbCritical
End Select

The compiler wants to know the function before it can use it

just declare the function before you call it

#include <stdio.h>

int Fibonacci(int number); //now the compiler knows, what the signature looks like. this is all it needs for now

int main(int argc, const char * argv[])
{
    int input;
    printf("Please give me a number : ");
    scanf("%d", &input);
    getchar();
    printf("The fibonacci number of %d is : %d", input, Fibonacci(input)); //!!!

}/* main */

int Fibonacci(int number)
{
//…

Assuming that your table is called 'Table1' and the column you need is 'Column' you can try this:

for i = 1 to Range("Table1").Rows.Count
   Range("Table1[Column]")(i)="PHEV"
next i

for example:

<ImageView android:id="@+id/image_view"     
  android:layout_width="wrap_content"  
  android:layout_height="wrap_content"  
  android:adjustViewBounds="true"  
  android:maxWidth="42dp"  
  android:maxHeight="42dp"  
  android:scaleType="fitCenter"  
  android:layout_marginLeft="3dp"  
  android:src="@drawable/icon"  
  /> 

Add property android:scaleType="fitCenter" and android:adjustViewBounds="true".

The following attribute on the ACTIVITY in AndroidManifest.xml is all you need:

android:configChanges="orientation"

So, the full activity node would be:

<activity android:name="Activity1"
          android:icon="@drawable/icon"
          android:label="App Name"
          android:excludeFromRecents="true"
          android:configChanges="orientation">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>
        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity>

See the Express docs as well as the Node docs for https.createServer (which is what express recommends to use):

var privateKey = fs.readFileSync( 'privatekey.pem' );
var certificate = fs.readFileSync( 'certificate.pem' );

https.createServer({
    key: privateKey,
    cert: certificate
}, app).listen(port);

Other options for createServer are at: http://nodejs.org/api/tls.html#tls_tls_createserver_options_secureconnectionlistener

       // Also place this code into base controller in contract function,            because ever controller extends base  controller
 if(Auth::id) {
  //here redirect your code or function
 }
if (Auth::guest()) {
       return Redirect::guest('login');
}

Solution for Kotlin:

val sourceContent = File("test.txt").readText(Charset.forName("windows-1251"))
val result = String(sourceContent.toByteArray())

Kotlin uses UTF-8 everywhere as default encoding.

Method toByteArray() has default argument - Charsets.UTF_8.

I am new to spring spent an hour trying to figure this out.

go to --- > application.properties

add these :

spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

(Reference: Chart.js)

N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion

Firstly, understand that DateTime objects aren't formatted. They just store the Year, Month, Day, Hour, Minute, Second, etc as a numeric value and the formatting occurs when you want to represent it as a string somehow. You can compare DateTime objects without formatting them.

To compare an input date with DateTime.Now, you need to first parse the input into a date and then compare just the Year/Month/Day portions:

DateTime inputDate;
if(!DateTime.TryParse(inputString, out inputDate))
    throw new ArgumentException("Input string not in the correct format.");

if(inputDate.Date == DateTime.Now.Date) {
    // Same date!
}

Check the header to make sure that the doctype is going to work with Internet Explorer without it having to 'guess' how to render it.

You can also force the render engine in IE 8/9 to use the earlier IE7 renderer. This also has the benefit of removing the 'compatibility view' icon in the address bar area.

Try putting this in your .htaccess:

Header set X-UA-Compatible IE=EmulateIE7  

Or, if you can write the headers:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7">

@mawtex you will want to do this just for IE8 as your site works fine in 7 and 9, just not 8.

This might help somebody. It took me days to finally figure it out. I am working in OBJ-C and I went to:

Project -> Build Phases -> Compile sources and added the new VC.m file I had just added.

I am working with legacy code and I am usually a swifty, new to OBJ-C so I didn't even think to import my .m files into a sources library.

EDIT:

Ran into this problem a second time and it was something else. This answer saved me after 5 hours of debugging. Tried all of the options on this thread and more. https://stackoverflow.com/a/13625967/7842175 Please give him credit if this helps you, but basically you might need to set your file to its target in file inspector.

All in all, this is a very vague Error code that could be caused for a lot of reasons, so keep on trying different options.

If you work with an IDE like NetBeans, you can specify the Xlint:unchecked compiler option in the propertys of your project.

Just go to projects window, right click in the project and then click in Properties.

In the window that appears search the Compiling category, and in the textbox labeled Additional Compiler Options set the Xlint:unchecked option.

Thus, the setting will remain set for every time you compile the project.

OK, I found this post: http://msdn.microsoft.com/en-us/library/aa479319.aspx

with this very illustrative diagram:

_{(source: microsoft.com)}

in essence, to get at those exception details i need to store them myself in Global.asax, for later retrieval on my custom error page.

it seems the best way is to do the bulk of the work in Global.asax, with the custom error pages handling helpful content rather than logic.

Whenever you want to redirect, send the headers:

header("Location: http://www.example.com/");

Remember you cant send data to the client before that, though.

simple and easy

Locale locale = new Locale("en", "US");
Resources res = getResources();
DisplayMetrics dm = res.getDisplayMetrics();
Configuration conf = res.getConfiguration();
conf.locale = locale;
res.updateConfiguration(conf, dm);

where "en" is language code and "US" is country code.

just remove this because constructor don't have a return type like void it will be like this :

private Flow()
    {
        X = x;
        Y = y;
    }  

Gwerder's solution wont work because hash = hmac.read(); happens before the stream is done being finalized. Thus AngraX's issues. Also the hmac.write statement is un-necessary in this example.

Instead do this:

var crypto    = require('crypto');
var hmac;
var algorithm = 'sha1';
var key       = 'abcdeg';
var text      = 'I love cupcakes';
var hash;

hmac = crypto.createHmac(algorithm, key);

// readout format:
hmac.setEncoding('hex');
//or also commonly: hmac.setEncoding('base64');

// callback is attached as listener to stream's finish event:
hmac.end(text, function () {
    hash = hmac.read();
    //...do something with the hash...
});

More formally, if you wish, the line

hmac.end(text, function () {

could be written

hmac.end(text, 'utf8', function () {

because in this example text is a utf string

You need to to create a new migration file using following command

rails generate migration drop_table_xyz

and write drop_table code in newly generated migration file (db/migration/xxxxxxx_drop_table_xyz) like

drop_table :tablename

Or if you wanted to drop table without migration, simply open rails console by

$ rails c

and execute following command

ActiveRecord::Base.connection.execute("drop table table_name")

or you can use more simplified command

ActiveRecord::Migration.drop_table(:table_name)

They both give you the same results but the key difference I see is that you cannot specify a ResourceType in DisplayName attribute. For an example in MVC 2, you had to subclass the DisplayName attribute to provide resource via localization. Display attribute (new in MVC3 and .NET4) supports ResourceType overload as an "out of the box" property.

For deleting use http://www.php.net/manual/en/function.unlink.php Hope you'll can to write logic?

Match any single character

• Use the dot . character as a wildcard to match any single character.

Example regex: a.c

abc   // match
a c   // match
azc   // match
ac    // no match
abbc  // no match

Match any specific character in a set

• Use square brackets [] to match any characters in a set.
• Use \w to match any single alphanumeric character: 0-9, a-z, A-Z, and _ (underscore).
• Use \d to match any single digit.
• Use \s to match any single whitespace character.

Example 1 regex: a[bcd]c

abc   // match
acc   // match
adc   // match
ac    // no match
abbc  // no match

Example 2 regex: a[0-7]c

a0c   // match
a3c   // match
a7c   // match
a8c   // no match
ac    // no match
a55c  // no match

Match any character except ...

Use the hat in square brackets [^] to match any single character except for any of the characters that come after the hat ^.

Example regex: a[^abc]c

aac   // no match
abc   // no match
acc   // no match
a c   // match
azc   // match
ac    // no match
azzc  // no match

(Don't confuse the ^ here in [^] with its other usage as the start of line character: ^ = line start, $ = line end.)

Match any character optionally

Use the optional character ? after any character to specify zero or one occurrence of that character. Thus, you would use .? to match any single character optionally.

Example regex: a.?c

abc   // match
a c   // match
azc   // match
ac    // match
abbc  // no match

Today being 2016, I think the cleanest solution is provided by pandas Timestamp:

from datetime import date
import pandas as pd
d = date.today()
pd.Timestamp(d)

Timestamp is the pandas equivalent of datetime and is interchangable with it in most cases. Check:

from datetime import datetime
isinstance(pd.Timestamp(d), datetime)

But in case you really want a vanilla datetime, you can still do:

pd.Timestamp(d).to_datetime()

Timestamps are a lot more powerful than datetimes, amongst others when dealing with timezones. Actually, Timestamps are so powerful that it's a pity they are so poorly documented...

The :: are used to dereference scopes.

const int x = 5;

namespace foo {
  const int x = 0;
}

int bar() {
  int x = 1;
  return x;
}

struct Meh {
  static const int x = 2;
}

int main() {
  std::cout << x; // => 5
  {
    int x = 4;
    std::cout << x; // => 4
    std::cout << ::x; // => 5, this one looks for x outside the current scope
  }
  std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
  std::cout << foo::x; // => 0, use the definition of x inside foo
  std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}

unrelated: cout and cin are not functions, but instances of stream objects.

EDIT fixed as Keine Lust suggested

Every minor version of Python, that is any 3.x and 2.x version, will install side-by-side with other versions on your computer. Only patch versions will upgrade existing installations.

So if you want to keep your installed Python 2.7 around, then just let it and install a new version using the installer. If you want to get rid of Python 2.7, you can uninstall it before or after installing a newer version—there is no difference to this.

Current Python 3 installations come with the py.exe launcher, which by default is installed into the system directory. This makes it available from the PATH, so you can automatically run it from any shell just by using py instead of python as the command. This avoids you having to put the current Python installation into PATH yourself. That way, you can easily have multiple Python installations side-by-side without them interfering with each other. When running, just use py script.py instead of python script.py to use the launcher. You can also specify a version using for example py -3 or py -3.6 to launch a specific version, otherwise the launcher will use the current default (which will usually be the latest 3.x).

Using the launcher, you can also run Python 2 scripts (which are often syntax incompatible to Python 3), if you decide to keep your Python 2.7 installation. Just use py -2 script.py to launch a script.

As for PyPI packages, every Python installation comes with its own folder where modules are installed into. So if you install a new version and you want to use modules you installed for a previous version, you will have to install them first for the new version. Current versions of the installer also offer you to install pip; it’s enabled by default, so you already have pip for every installation. Unless you explicitly add a Python installation to the PATH, you cannot just use pip though. Luckily, you can also simply use the py.exe launcher for this: py -m pip runs pip. So for example to install Beautiful Soup for Python 3.6, you could run py -3.6 -m pip install beautifulsoup4.

if you implement with dialog edittext. use like this:. its same with use to other edittext.

dialog.getInputEditText().addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence charSequence, int start, int before, int count) {
    }

    @Override
    public void onTextChanged(CharSequence charSequence, int start, int before, int count) {
        if (start<2){
                dialog.getActionButton(DialogAction.POSITIVE).setEnabled(false);
            }else{
                double size =  Double.parseDouble(charSequence.toString());
                if (size > 0.000001 && size < 0.999999){
                    dialog.getActionButton(DialogAction.POSITIVE).setEnabled(true);
                }else{
                    ToastHelper.show(HistoryActivity.this, "Size must between 0.1 - 0.9");
                    dialog.getActionButton(DialogAction.POSITIVE).setEnabled(false);
                }

            }
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
});

You can use this example.

Inside controller:

$scope.data = {
    'myVal': 33,
    'maxVal': 55,
    'indexCount': function(count) {
        var cnt = 10;
        if (typeof count === 'number') {
            cnt = count;
        }
        return new Array(cnt);
    }
};

Example for select element at the HTML code side:

<select ng-model="data.myVal" value="{{ data.myVal }}">
    <option ng-repeat="i in data.indexCount(data.maxVal) track by $index" value="{{ $index + 1 }}">{{ $index + 1 }}</option>
</select>

It's in MVVM Light, get it from the MVVM Light Download Page.

What helped me a lot was to run the Maven archetype:generate goal and select from one of the archetypes, some of which seem to be updated regularly (in particular JBoss seems to be well maintained).

mvn archetype:generate

Hundreds of archetypes appeared in a numbered list from which to select (519 as of now!). The goal, still running, prompted me to make a selection by entering a number or entering a search string e.g.:

513: remote -> org.xwiki.commons:xwiki-commons-component-archetype
514: remote -> org.xwiki.rendering:xwiki-rendering-archetype-macro
515: remote -> org.zkoss:zk-archetype-component
516: remote -> org.zkoss:zk-archetype-webapp
517: remote -> ru.circumflex:circumflex-archetype (-)
518: remote -> se.vgregion.javg.maven.archetypes:javg-minimal-archetype (-)
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains):

I entered the search string "ear," which reduced the list to only 8 items (as of today):

Choose archetype:
1: remote -> org.codehaus.mojo.archetypes:ear-j2ee14 (-)
2: remote -> org.codehaus.mojo.archetypes:ear-javaee6 (-)
3: remote -> org.codehaus.mojo.archetypes:ear-jee5 (-)
4: remote -> org.hibernate:hibernate-search-quickstart (-)
5: remote -> org.jboss.spec.archetypes:jboss-javaee6-ear-webapp 
6: remote -> org.jboss.spec.archetypes:jboss-javaee6-webapp-ear-archetype
7: remote -> org.jboss.spec.archetypes:jboss-javaee6-webapp-ear-archetype-blank
8: remote -> org.ow2.weblab.tools.maven:weblab-archetype-searcher

I selected "org.jboss.spec.archetypes:jboss-javaee6-ear-webapp" (by entering the selection "5" in this example).

Next, the goal asked me to enter the groupId, artifactId, package names, etc., and it then generated the following well-documented example application:

32 directories, 23 files

./Foo-web/pom.xml

I know this is a little old but I wanted to add an updated answer with f-strings which were introduced in Python version 3.6:

msg['Subject'] = f'Auto Hella Restart Report {sys.argv[1]}'

If you want to use position: absolute; on the div with position: relative; on the td you will run into issues. FF, safari, and chrome (mac, not PC though) will not position the div relative to the td (like you would expect) this is also true for divs with display: table-whatever; so if you want to do that you need two divs, one for the container width: 100%; height: 100%; and no border so it fills the td without any visual impact. and then the absolute one.

other than that why not just split the cell?

Simple but usefull way:

$query = $this->db->distinct()->select('order_id')->get_where('tbl_order_details', array('seller_id' => $seller_id));
        return $query;

In the constructor of Startup class, you can access appsettings.json and many other settings using the injected IConfiguration object:

Startup.cs Constructor

    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;

        //here you go
        var myvalue = Configuration["Grandfather:Father:Child"];

    }

public IConfiguration Configuration { get; }

Contents of appsettings.json

  {
  "Grandfather": {
    "Father": {
      "Child": "myvalue"
    }
  }

You can do this using del and the /S flag (to tell it to recurse all files from all subdirectories):

del /S C:\Path\to\directory\*

The RD command can also be used. Recursively delete quietly without a prompt:

@RD /S /Q %VAR_PATH%

Rmdir (rd)

Performance test for in_array vs array_intersect:

$a1 = array(2,4,8,11,12,13,14,15,16,17,18,19,20);

$a2 = array(3,20);

$intersect_times = array();
$in_array_times = array();
for($j = 0; $j < 10; $j++)
{
    /***** TEST ONE array_intersect *******/
    $t = microtime(true);
    for($i = 0; $i < 100000; $i++)
    {
        $x = array_intersect($a1,$a2);
        $x = empty($x);

Install Inspect-it

pip3 install inspect-it --user

Code

import inspect;print(*['\n\x1b[0;36;1m| \x1b[0;32;1m{:25}\x1b[0;36;1m| \x1b[0;35;1m{}'.format(str(x.function), x.filename+'\x1b[0;31;1m:'+str(x.lineno)+'\x1b[0m') for x in inspect.stack()])

you can Make a snippet of this line

it will show you a list of the function call stack with a filename and line number

list from start to where you put this line

One approach would be to just use the ModelState:

ModelState.AddModelError("", "Error in cloud - GetPLUInfo" + ex.Message);

and then on the view do something like this:

@Html.ValidationSummary()

where you want the errors to display. If there are no errors, it won't display, but if there are you'll get a section that lists all the errors.

How about putting the checkbox into the label, making the label automatically "click sensitive" for the check box, and giving the checkbox a onchange event?

<label ..... ><input type="checkbox" onchange="toggleCheckbox(this)" .....> 

function toggleCheckbox(element)
 {
   element.checked = !element.checked;
 }

This will additionally catch users using a keyboard to toggle the check box, something onclick would not.

You will need to configure you IIS (assuming this is the web server your are/will using) allowing access from WLAN/LAN to specific users (or anonymous). Allow IIS trought your firewall if you have one.

Your application won't need to be changed, that's just networking problems ans configuration you will have to face to allow acces only trought LAN and WLAN.

As mentioned in other posts here - setting breakpoints in your code and walking thru the code to see if it behaves as you expected is a great way to learn something like Django until you have a good sense of how it all behaves - and what your code is doing.

To do this I would recommend using WingIde. Just like other mentioned IDEs nice and easy to use, nice layout and also easy to set breakpoints evaluate / modify the stack etc. Perfect for visualizing what your code is doing as you step through it. I'm a big fan of it.

Also I use PyCharm - it has excellent static code analysis and can help sometimes spot problems before you realize they are there.

As mentioned already django-debug-toolbar is essential - https://github.com/django-debug-toolbar/django-debug-toolbar

And while not explicitly a debug or analysis tool - one of my favorites is SQL Printing Middleware available from Django Snippets at https://djangosnippets.org/snippets/290/

This will display the SQL queries that your view has generated. This will give you a good sense of what the ORM is doing and if your queries are efficient or you need to rework your code (or add caching).

I find it invaluable for keeping an eye on query performance while developing and debugging my application.

Just one other tip - I modified it slightly for my own use to only show the summary and not the SQL statement.... So I always use it while developing and testing. I also added that if the len(connection.queries) is greater than a pre-defined threshold it displays an extra warning.

Then if I spot something bad (from a performance or number of queries perspective) is happening I turn back on the full display of the SQL statements to see exactly what is going on. Very handy when you are working on a large Django project with multiple developers.

Place your script inside the body tag

<body>
  // Rest of html
  <script>
  function hideButton() {
    $(".loading").hide();
  }
function showButton() {
  $(".loading").show();
}
</script> 
< /body>

If you check this JSFIDDLE and click on javascript, you will see the load Type body is selected

I had this noted from somewhere:

adding text-transform to input to remove it

input.button {
    text-indent:-9999px;
    text-transform:capitalize;
}

I use RStudio or Emacs and always use the editor shortcuts available to comment regions. If this is not a possibility then you could use Paul's answer but this only works if your code is syntactically correct.

Here is another dirty way I came up with, wrap it in scan() and remove the result. It does store the comment in memory for a short while so it will probably not work with very large comments. Best still is to just put # signs in front of every line (possibly with editor shortcuts).

foo <- scan(what="character")
These are comments
These are still comments
Can also be code:
x <- 1:10
One line must be blank

rm(foo)

There are three ways to approach this problem:

• Call next() on the Scanner, and extract the first character of the String (e.g. charAt(0)) If you want to read the rest of the line as characters, iterate over the remaining characters in the String. Other answers have this code.

• Use setDelimiter("") to set the delimiter to an empty string. This will cause next() to tokenize into strings that are exactly one character long. So then you can repeatedly call next().charAt(0) to iterate the characters. You can then set the delimiter to its original value and resume scanning in the normal way!

• Use the Reader API instead of the Scanner API. The Reader.read() method delivers a single character read from the input stream. For example:

  Reader reader = new InputStreamReader(System.in);
  int ch = reader.read();
  if (ch != -1) {  // check for EOF
      // we have a character ...
  }
  

When you read from the console via System.in, the input is typically buffered by the operating system, and only "released" to the application when the user types ENTER. So if you intend your application to respond to individual keyboard strokes, this is not going to work. You would need to do some OS-specific native code stuff to turn off or work around line-buffering for console at the OS level.

mysqli_select_db() should have 2 parameters, the connection link and the database name -

mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));

Using mysqli_error in the die statement will tell you exactly what is wrong as opposed to a generic error message.

I don't think there is a SAP parameter for that kind of result. Though the code below will deliver.

    write result.  

  ENDAT.

ENDLOOP.

Try this:

colnames(DF) = DF[1, ] # the first row will be the header
DF = DF[-1, ]          # removing the first row.

However, get a look if the data has been properly read. If you data.frame has numeric variables but the first row were characters, all the data has been read as character. To avoid this problem, it's better to save the data and read again with header=TRUE as you suggest. You can also get a look to this question: Reading a CSV file organized horizontally.

If ensure_ascii is false, then the return value will be a unicode instance subject to normal Python str to unicode coercion rules instead of being escaped to an ASCII str.

Differences in SOAP versions

Both SOAP Version 1.1 and SOAP Version 1.2 are World Wide Web Consortium (W3C) standards. Web services can be deployed that support not only SOAP 1.1 but also support SOAP 1.2. Some changes from SOAP 1.1 that were made to the SOAP 1.2 specification are significant, while other changes are minor.

The SOAP 1.2 specification introduces several changes to SOAP 1.1. This information is not intended to be an in-depth description of all the new or changed features for SOAP 1.1 and SOAP 1.2. Instead, this information highlights some of the more important differences between the current versions of SOAP.

The changes to the SOAP 1.2 specification that are significant include the following updates: SOAP 1.1 is based on XML 1.0. SOAP 1.2 is based on XML Information Set (XML Infoset). The XML information set (infoset) provides a way to describe the XML document with XSD schema. However, the infoset does not necessarily serialize the document with XML 1.0 serialization on which SOAP 1.1 is based.. This new way to describe the XML document helps reveal other serialization formats, such as a binary protocol format. You can use the binary protocol format to compact the message into a compact format, where some of the verbose tagging information might not be required.

In SOAP 1.2 , you can use the specification of a binding to an underlying protocol to determine which XML serialization is used in the underlying protocol data units. The HTTP binding that is specified in SOAP 1.2 - Part 2 uses XML 1.0 as the serialization of the SOAP message infoset.

SOAP 1.2 provides the ability to officially define transport protocols, other than using HTTP, as long as the vendor conforms to the binding framework that is defined in SOAP 1.2. While HTTP is ubiquitous, it is not as reliable as other transports including TCP/IP and MQ. SOAP 1.2 provides a more specific definition of the SOAP processing model that removes many of the ambiguities that might lead to interoperability errors in the absence of the Web Services-Interoperability (WS-I) profiles. The goal is to significantly reduce the chances of interoperability issues between different vendors that use SOAP 1.2 implementations. SOAP with Attachments API for Java (SAAJ) can also stand alone as a simple mechanism to issue SOAP requests. A major change to the SAAJ specification is the ability to represent SOAP 1.1 messages and the additional SOAP 1.2 formatted messages. For example, SAAJ Version 1.3 introduces a new set of constants and methods that are more conducive to SOAP 1.2 (such as getRole(), getRelay()) on SOAP header elements. There are also additional methods on the factories for SAAJ to create appropriate SOAP 1.1 or SOAP 1.2 messages. The XML namespaces for the envelope and encoding schemas have changed for SOAP 1.2. These changes distinguish SOAP processors from SOAP 1.1 and SOAP 1.2 messages and supports changes in the SOAP schema, without affecting existing implementations. Java Architecture for XML Web Services (JAX-WS) introduces the ability to support both SOAP 1.1 and SOAP 1.2. Because JAX-RPC introduced a requirement to manipulate a SOAP message as it traversed through the run time, there became a need to represent this message in its appropriate SOAP context. In JAX-WS, a number of additional enhancements result from the support for SAAJ 1.3.

There is not difine POST AND GET method for particular android....but all here is differance

GET The GET method appends name/value pairs to the URL, allowing you to retrieve a resource representation. The big issue with this is that the length of a URL is limited (roughly 3000 char) resulting in data loss should you have to much stuff in the form on your page, so this method only works if there is a small number parameters.

What does this mean for me? Basically this renders the GET method worthless to most developers in most situations. Here is another way of looking at it: the URL could be truncated (and most likely will be give today's data-centric sites) if the form uses a large number of parameters, or if the parameters contain large amounts of data. Also, parameters passed on the URL are visible in the address field of the browser (YIKES!!!) not the best place for any kind of sensitive (or even non-sensitive) data to be shown because you are just begging the curious user to mess with it.

POST The alternative to the GET method is the POST method. This method packages the name/value pairs inside the body of the HTTP request, which makes for a cleaner URL and imposes no size limitations on the forms output, basically its a no-brainer on which one to use. POST is also more secure but certainly not safe. Although HTTP fully supports CRUD, HTML 4 only supports issuing GET and POST requests through its various elements. This limitation has held Web applications back from making full use of HTTP, and to work around it, most applications overload POST to take care of everything but resource retrieval.

With a character class this big it is easier to say what you want to keep. A caret in the first position of a character class inverts its sense, so you can write

$varTemp =~ s/[^"%'+\-0-9<=>a-z_{|}]+//gi

or, using the more efficient tr

$varTemp =~ tr/"%'+\-0-9<=>A-Z_a-z{|}//cd

2018's update, and Let's use standard HTML+CSS=PDF equation!

There are good news for HTML-to-PDF demands. As this answer showed, the W3C standard css-break-3 will solve the problem... It is a Candidate Recommendation with plan to turn into definitive Recommendation in 2017 or 2018, after tests.

As not-so-standard there are solutions, with plugins for C#, as showed by print-css.rocks.

I guess you can do this in 5 minute without any further IP/port forwarding, for presenting your local websites temporary.

All you need to do it, go to http://ngrok.com Download small tool extract and run that tool as administrator

Enter command
ngrok http 80

You will see it will connect to server and will create a temporary URL for you which you can share to your friend and let him browse localhost or any of its folder.

How do I access/share xampp or localhost website from another computer

As mentioned in previous replies, you can use something like: .settimeout() For example:

import socket

s = socket.socket()

s.settimeout(1) # Sets the socket to timeout after 1 second of no activity

host, port = "somehost", 4444
s.connect((host, port))

s.send("Hello World!\r\n")

try:
    rec = s.recv(100) # try to receive 100 bytes
except socket.timeout: # fail after 1 second of no activity
    print("Didn't receive data! [Timeout]")
finally:
    s.close()

I hope this helps!!

The default value for client_max_body_size directive is 1 MiB.

It can be set in http, server and location context — as in the most cases, this directive in a nested block takes precedence over the same directive in the ancestors blocks.

Excerpt from the ngx_http_core_module documentation:

Syntax:   client_max_body_size size;
Default:  client_max_body_size 1m;
Context:  http, server, location

Sets the maximum allowed size of the client request body, specified in the “Content-Length” request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

Don't forget to reload configuration by nginx -s reload or service nginx reload commands prepending with sudo (if any).

Seaching for answer I couldn't find any to be easy and flexible at the same time, then I found the Spring Security Reference and I realized there are near to perfect solutions. AOP solutions often are the greatest ones for testing, and Spring provides it with @WithMockUser, @WithUserDetails and @WithSecurityContext, in this artifact:

<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-test</artifactId>
    <version>4.2.2.RELEASE</version>
    <scope>test</scope>
</dependency>

In most cases, @WithUserDetails gathers the flexibility and power I need.

How @WithUserDetails works?

Basically you just need to create a custom UserDetailsService with all the possible users profiles you want to test. E.g

@TestConfiguration
public class SpringSecurityWebAuxTestConfig {

    @Bean
    @Primary
    public UserDetailsService userDetailsService() {
        User basicUser = new UserImpl("Basic User", "[email protected]", "password");
        UserActive basicActiveUser = new UserActive(basicUser, Arrays.asList(
                new SimpleGrantedAuthority("ROLE_USER"),
                new SimpleGrantedAuthority("PERM_FOO_READ")
        ));

        User managerUser = new UserImpl("Manager User", "[email protected]", "password");
        UserActive managerActiveUser = new UserActive(managerUser, Arrays.asList(
                new SimpleGrantedAuthority("ROLE_MANAGER"),
                new SimpleGrantedAuthority("PERM_FOO_READ"),
                new SimpleGrantedAuthority("PERM_FOO_WRITE"),
                new SimpleGrantedAuthority("PERM_FOO_MANAGE")
        ));

        return new InMemoryUserDetailsManager(Arrays.asList(
                basicActiveUser, managerActiveUser
        ));
    }
}

Now we have our users ready, so imagine we want to test the access control to this controller function:

@RestController
@RequestMapping("/foo")
public class FooController {

    @Secured("ROLE_MANAGER")
    @GetMapping("/salute")
    public String saluteYourManager(@AuthenticationPrincipal User activeUser)
    {
        return String.format("Hi %s. Foo salutes you!", activeUser.getUsername());
    }
}

Here we have a get mapped function to the route /foo/salute and we are testing a role based security with the @Secured annotation, although you can test @PreAuthorize and @PostAuthorize as well. Let's create two tests, one to check if a valid user can see this salute response and the other to check if it's actually forbidden.

@RunWith(SpringRunner.class)
@SpringBootTest(
        webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT,
        classes = SpringSecurityWebAuxTestConfig.class
)
@AutoConfigureMockMvc
public class WebApplicationSecurityTest {

    @Autowired
    private MockMvc mockMvc;

    @Test
    @WithUserDetails("[email protected]")
    public void givenManagerUser_whenGetFooSalute_thenOk() throws Exception
    {
        mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
                .accept(MediaType.ALL))
                .andExpect(status().isOk())
                .andExpect(content().string(containsString("[email protected]")));
    }

    @Test
    @WithUserDetails("[email protected]")
    public void givenBasicUser_whenGetFooSalute_thenForbidden() throws Exception
    {
        mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
                .accept(MediaType.ALL))
                .andExpect(status().isForbidden());
    }
}

As you see we imported SpringSecurityWebAuxTestConfig to provide our users for testing. Each one used on its corresponding test case just by using a straightforward annotation, reducing code and complexity.

Better use @WithMockUser for simpler Role Based Security

As you see @WithUserDetails has all the flexibility you need for most of your applications. It allows you to use custom users with any GrantedAuthority, like roles or permissions. But if you are just working with roles, testing can be even easier and you could avoid constructing a custom UserDetailsService. In such cases, specify a simple combination of user, password and roles with @WithMockUser.

@Target({ElementType.METHOD, ElementType.TYPE})
@Retention(RetentionPolicy.RUNTIME)
@Inherited
@Documented
@WithSecurityContext(
    factory = WithMockUserSecurityContextFactory.class
)
public @interface WithMockUser {
    String value() default "user";

    String username() default "";

    String[] roles() default {"USER"};

    String password() default "password";
}

The annotation defines default values for a very basic user. As in our case the route we are testing just requires that the authenticated user be a manager, we can quit using SpringSecurityWebAuxTestConfig and do this.

@Test
@WithMockUser(roles = "MANAGER")
public void givenManagerUser_whenGetFooSalute_thenOk() throws Exception
{
    mockMvc.perform(MockMvcRequestBuilders.get("/foo/salute")
            .accept(MediaType.ALL))
            .andExpect(status().isOk())
            .andExpect(content().string(containsString("user")));
}

Notice that now instead of the user [email protected] we are getting the default provided by @WithMockUser: user; yet it won't matter because what we really care about is his role: ROLE_MANAGER.

Conclusions

As you see with annotations like @WithUserDetails and @WithMockUser we can switch between different authenticated users scenarios without building classes alienated from our architecture just for making simple tests. Its also recommended you to see how @WithSecurityContext works for even more flexibility.

You need to "clear" the float after every 6 images. So with your current code, change the styles for containerdivNewLine to:

.containerdivNewLine { clear: both; float: left; display: block; position: relative; } 

I had a similar issue with Datagrip and none of these solutions worked.

Once I restarted the Datagrip Client it was no longer an issue and I could drop tables again.

you can simply write $('span#a').length to get the length.

Here is the Solution for your code:

console.log($('span#a').length);
