There are four ways I've found to put a newline into the minibuffer.

1. C-o

2. C-q C-j

3. C-q 12 (12 is the octal value of newline)

4. C-x o to the main window, kill a newline with C-k, then C-x o back to the minibuffer, yank it with C-y

Here is the issue

  $total_result = $result->num_rows;

try this

<?php
if ($result = $mysqli->query("SELECT * FROM players ORDER BY id"))
{
    if ($result->num_rows > 0)
    {
        $total_result = $result->num_rows;
        $total_pages = ceil($total_result / $per_page);

        if(isset($_GET['page']) && is_numeric($_GET['page']))
        {
            $show_page = $_GET['page'];

            if ($show_page > 0 && $show_page <= $total_pages)
            {
                $start = ($show_page - 1) * $per_page;
                $end = $start + $per_page;

You should have header files (.h) that contain the function's declaration, then a corresponding .cpp file that contains the definition. You then include the header file everywhere you need it. Note that the .cpp file that contains the definitions also needs to include (it's corresponding) header file.

// main.cpp
#include "second.h"
int main () {
    secondFunction();
}

// second.h
void secondFunction();

// second.cpp
#include "second.h"
void secondFunction() {
   // do stuff
}

Initially used only ViewDidLoad with tableView. On testing with loss of Wifi, by setting device to airplane mode, realized that the table did not refresh with return of Wifi. In fact, there appears to be no way to refresh tableView on the device even by hitting the home button with background mode set to YES in -Info.plist.

My solution:

-(void) viewWillAppear: (BOOL) animated { [self.tableView reloadData];}

This will work on both BSD and GNU.

awk '{arr[i++]=$0} END {while (i>0) print arr[--i] }' filename

I add my answer, similar to others but maybe it will be the quickest one to read and implement.

NOTE: Rebase is not needed in this case.

Assume I have a repo1 and two branches master and dev-user.

dev-user is a branch done at a certain state of master.

Now assume that both dev-user and master advance.

At some point I want dev-user to get all the commits made in master.

How do I do it?

I go first in my repository root folder

cd name_of_the_repository

then

git checkout master 
git pull 
git checkout dev-user
git pull
git merge master 
git push 

I hope this helps someone else in the same situation.

If the browser people see this as a security and/or usability problem, then the answer to your question is to simply not close the window, since by definition they will come up with solutions for your workaround anyway. There is a nice summation about the reasoning why the choice have been in the firefox bug database https://bugzilla.mozilla.org/show_bug.cgi?id=190515#c70

So what can you do?

Change the specification of your website, so that you have a solution for these people. You could for instance take it as an opportunity to direct them to a partner.

That is, see it as a handoff to someone else that (potentially) needs it. As an example, Hanselman had a recent article about what to do in the other similar situation, namely 404 errors: http://www.hanselman.com/blog/PutMissingKidsOnYour404PageEntirelyClientSideSolutionWithYQLJQueryAndMSAjax.aspx

window.location.href.split('/');

Will give you an array containing all the URL parts, which you can access like a normal array.

Or an ever more elegant solution suggested by @Dylan, with only the path parts:

window.location.pathname.split('/');

On laravel 5.6 it has a very simple solution:

User::where('username', $username)->first()->groupName;

It will return groupName as a string.

There is no linguistic support to do what you're asking for.

You can reflectively access the members of a type at run-time using reflection (e.g. with Class.getDeclaredFields() to get an array of Field), but depending on what you're trying to do, this may not be the best solution.

• How could Reflection not lead to code smells?
• Dumping a java object’s properties

Example

Here's a simple example to show only some of what reflection is capable of doing.

import java.lang.reflect.*;

public class DumpFields {
    public static void main(String[] args) {
        inspect(String.class);
    }
    static <T> void inspect(Class<T> klazz) {
        Field[] fields = klazz.getDeclaredFields();
        System.out.printf("%d fields:%n", fields.length);
        for (Field field : fields) {
            System.out.printf("%s %s %s%n",
                Modifier.toString(field.getModifiers()),
                field.getType().getSimpleName(),
                field.getName()
            );
        }
    }
}

The above snippet uses reflection to inspect all the declared fields of class String; it produces the following output:

7 fields:
private final char[] value
private final int offset
private final int count
private int hash
private static final long serialVersionUID
private static final ObjectStreamField[] serialPersistentFields
public static final Comparator CASE_INSENSITIVE_ORDER

Effective Java 2nd Edition, Item 53: Prefer interfaces to reflection

These are excerpts from the book:

Given a Class object, you can obtain Constructor, Method, and Field instances representing the constructors, methods and fields of the class. [They] let you manipulate their underlying counterparts reflectively. This power, however, comes at a price:

• You lose all the benefits of compile-time checking.
• The code required to perform reflective access is clumsy and verbose.
• Performance suffers.

As a rule, objects should not be accessed reflectively in normal applications at runtime.

There are a few sophisticated applications that require reflection. Examples include [...omitted on purpose...] If you have any doubts as to whether your application falls into one of these categories, it probably doesn't.

In EF 6.2 using FluentAPI, you can use HasIndex()

modelBuilder.Entity<User>().HasIndex(u => u.UserName).IsUnique();

This worked for me

<div style="display: flex; position: absolute; width: 100%;">
  <div style="white-space: nowrap; overflow: hidden;text-overflow: ellipsis;">
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Integer nec odio. Praesent libero. Sed cursus ante dapibus diam. Sed nisi.
  </div>
</div>

Adding position:absolute to the parent container made it work.

PS: This is for anyone looking for a solution to dynamically truncating text.

EDIT: This was meant to be an answer for this question but since they are related and it could help someone on this question I shall also leave it here instead of deleting it.

        <input type="file" id="picfile" name="picf" />
       <input type="text" id="txtName" style="width: 144px;" />
 $("#btncatsave").click(function () {
var Name = $("#txtName").val();
var formData = new FormData();
var totalFiles = document.getElementById("picfile").files.length;

                    var file = document.getElementById("picfile").files[0];
                    formData.append("FileUpload", file);
                    formData.append("Name", Name);

$.ajax({
                    type: "POST",
                    url: '/Category_Subcategory/Save_Category',
                    data: formData,
                    dataType: 'json',
                    contentType: false,
                    processData: false,
                    success: function (msg) {

                                 alert(msg);

                    },
                    error: function (error) {
                        alert("errror");
                    }
                });

});

 [HttpPost]
    public ActionResult Save_Category()
    {
      string Name=Request.Form[1]; 
      if (Request.Files.Count > 0)
        {
            HttpPostedFileBase file = Request.Files[0];
         }


    }

if you want to add directly to input as attribute, use this

 onclick="return false;" 

<input id = "btnPlay" type="button" onclick="return false;" value="play" /> 

this will prevent form submit behaviour

UrlConnection is an awkward API to work with. HttpClient is by far the better API and it'll spare you from loosing time searching how to achieve certain things like this stackoverflow question illustrates perfectly. I write this after having used the jdk HttpUrlConnection in several REST clients. Furthermore when it comes to scalability features (like threadpools, connection pools etc.) HttpClient is superior

You can reset the plot by doing this:

dev.off()

It appears that a button that is used as the OK or CANCEL button for a ModalPopupExtender cannot have a click event. I tested this out by removing the

OkControlID="ModalOKButton"

from the ModalPopupExtender tag, and the button click fires. I'll need to figure out another way to send the data to the server.

You need to add use Response; facade in header at your file.

Only then you can successfully retrieve your data with

return Response::json($data);

this.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, theSizeIWant));

Problem solved!

NOTE: Be sure to use the parent Layout's LayoutParams. Mine is LinearLayout.LayoutParams!

Simply add an extension to the -i flag. This basically creates a backup file with the original file.

sed -i.bakup 's/linenumber/number/' ~/.vimrc

sed will execute without the error

Some browser may block popup created by window.open(url, "_blank");. An alternative is to create a link and click on it.

...

  constructor(@Inject(DOCUMENT) private document: Document) {}
...

  openNewWindow(): void {
    const link = this.document.createElement('a');
    link.target = '_blank';
    link.href = 'http://www.your-url.com';
    link.click();
    link.remove();
  }

collect(Collectors.toList());

This is the call which you can use to convert any Stream to List.

more concretely:

    List<String> myList = stream.collect(Collectors.toList()); 

from:

https://www.geeksforgeeks.org/collectors-tolist-method-in-java-with-examples/

This may work for you:

set define off

Otherwise the ampersand needs to be at the end of a string,

'StackOverflow &' || ' you'

EDIT: I was click-happy when saving... This was referenced from a blog.

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

You can do something like

for(var k in result) {
   console.log(k, result[k]);
}

which loops over all the keys in the returned json and prints the values. However, if you have a nested structure, you will need to use

typeof result[k] === "object"

to determine if you have to loop over the nested objects. Most APIs I have used, the developers know the structure of what is being returned, so this is unnecessary. However, I suppose it's possible that this expectation is not good for all cases.

if you have xcopy, you can use the /E param, which will copy directories and subdirectories and the files within them, including maintaining the directory structure for empty directories

xcopy [source] [destination] /E

For google maps v2 - GMap2:

ar map = new GMap2(document.getElementById("google_map"));
map.disableScrollWheelZoom();

Here's another way to do for multiple Button(In this case ImageView)

MainActivity.java

findViewById(R.id.arrowIV).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                if (strokeWidthIV.getAlpha() == 0f) {
                    findViewById(R.id.arrowIV).animate().rotationBy(180);

                    strokeWidthIV.animate().translationXBy(-120 * 4).alpha(1f);
                    findViewById(R.id.colorChooseIV).animate().translationXBy(-120 * 3).alpha(1f);
                    findViewById(R.id.saveIV).animate().translationXBy(-120 * 2).alpha(1f);
                    findViewById(R.id.clearAllIV).animate().translationXBy(-120).alpha(1f);
                } else {
                    findViewById(R.id.arrowIV).animate().rotationBy(180);

                    strokeWidthIV.animate().translationXBy(120 * 4).alpha(0f);
                    findViewById(R.id.colorChooseIV).animate().translationXBy(120 * 3).alpha(0f);
                    findViewById(R.id.saveIV).animate().translationXBy(120 * 2).alpha(0f);
                    findViewById(R.id.clearAllIV).animate().translationXBy(120).alpha(0f);
                }
            }

set PYTHONIOENCODING=utf-8
set PYTHONLEGACYWINDOWSSTDIO=utf-8

You may or may not need to set that second environment variable PYTHONLEGACYWINDOWSSTDIO.

Alternatively, this can be done in code (although it seems that doing it through env vars is recommended):

sys.stdin.reconfigure(encoding='utf-8')
sys.stdout.reconfigure(encoding='utf-8')

Additionally: Reproducing this error was a bit of a pain, so leaving this here too in case you need to reproduce it on your machine:

set PYTHONIOENCODING=windows-1252
set PYTHONLEGACYWINDOWSSTDIO=windows-1252

Use time.mktime() to convert the time tuple (in localtime) into seconds since the Epoch, then use datetime.fromtimestamp() to get the datetime object.

from datetime import datetime
from time import mktime

dt = datetime.fromtimestamp(mktime(struct))

Based on the above answer I've written a small extension class to work with CSS and JS files:

public static class TimestampedContentExtensions
{
    public static string VersionedContent(this UrlHelper helper, string contentPath)
    {
        var context = helper.RequestContext.HttpContext;

        if (context.Cache[contentPath] == null)
        {
            var physicalPath = context.Server.MapPath(contentPath);
            var version = @"v=" + new FileInfo(physicalPath).LastWriteTime.ToString(@"yyyyMMddHHmmss");

            var translatedContentPath = helper.Content(contentPath);

            var versionedContentPath =
                contentPath.Contains(@"?")
                    ? translatedContentPath + @"&" + version
                    : translatedContentPath + @"?" + version;

            context.Cache.Add(physicalPath, version, null, DateTime.Now.AddMinutes(1), TimeSpan.Zero,
                CacheItemPriority.Normal, null);

            context.Cache[contentPath] = versionedContentPath;
            return versionedContentPath;
        }
        else
        {
            return context.Cache[contentPath] as string;
        }
    }
}

Instead of writing something like:

<link href="@Url.Content(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.Content(@"~/Scripts/bootstrap.min.js")"></script>

You can now write:

<link href="@Url.VersionedContent(@"~/Content/bootstrap.min.css")" rel="stylesheet" type="text/css" />
<script src="@Url.VersionedContent(@"~/Scripts/bootstrap.min.js")"></script>

I.e. simply replace Url.Content with Url.VersionedContent.

Generated URLs look something like:

<link href="/Content/bootstrap.min.css?v=20151104105858" rel="stylesheet" type="text/css" />
<script src="/Scripts/bootstrap.min.js?v=20151029213517"></script>

If you use the extension class you might want to add error handling in case the MapPath call doesn't work, since contentPath isn't a physical file.

You will not able to test the app using the Google-Play-Service library in emulator. In order to test that app in emulator you need to install some system framework in your emulator to make it work.

Refer the above answer to install Google play service on your emulator.

PHP syntax is little different in case of concatenation from JavaScript. Instead of (+) plus a (.) period is used for string concatenation.

<?php

$selectBox = '<select name="number">';
for ($i=1;$i<=100;$i++)
{
    $selectBox += '<option value="' . $i . '">' . $i . '</option>'; // <-- (Wrong) Replace + with .
    $selectBox .= '<option value="' . $i . '">' . $i . '</option>'; // <-- (Correct) Here + is replaced .
}
$selectBox += '</select>'; // <-- (Wrong) Replace + with .
$selectBox .= '</select>'; // <-- (Correct) Here + is replaced .
echo $selectBox;

?>

Correct output:

'{"data":[{"id":"1","reason":"hello\\nworld"},{"id":"2","reason":"it\\nworks"}]}'

function json_entities( $data = null )
{           
    //stripslashes
    return str_replace( '\n',"\\"."\\n",
        htmlentities(
            utf8_encode( json_encode( $data)  ) , 
            ENT_QUOTES | ENT_IGNORE, 'UTF-8' 
        )
    );
}

You must define the class before creating an instance of the class. Move the invocation of Something to the end of the script.

You can try to put the cart before the horse and invoke procedures before they are defined, but it will be an ugly hack and you will have to roll your own as defined here:

Make function definition in a python file order independent

The reason the encoded array is longer by about a quarter is that base-64 encoding uses only six bits out of every byte; that is its reason of existence - to encode arbitrary data, possibly with zeros and other non-printable characters, in a way suitable for exchange through ASCII-only channels, such as e-mail.

The way you get your original array back is by using Convert.FromBase64String:

 byte[] temp_backToBytes = Convert.FromBase64String(temp_inBase64);

We should first read the documentation on proxy_pass carefully and fully.

The URI passed to upstream server is determined based on whether "proxy_pass" directive is used with URI or not. Trailing slash in proxy_pass directive means that URI is present and equal to /. Absense of trailing slash means hat URI is absent.

Proxy_pass with URI:

location /some_dir/ {
    proxy_pass http://some_server/;
}

With the above, there's the following proxy:

http:// your_server/some_dir/ some_subdir/some_file ->
http:// some_server/          some_subdir/some_file

Basically, /some_dir/ gets replaced by / to change the request path from /some_dir/some_subdir/some_file to /some_subdir/some_file.

Proxy_pass without URI:

location /some_dir/ {
    proxy_pass http://some_server;
}

With the second (no trailing slash): the proxy goes like this:

http:// your_server /some_dir/some_subdir/some_file ->
http:// some_server /some_dir/some_subdir/some_file

Basically, the full original request path gets passed on without changes.

So, in your case, it seems you should just drop the trailing slash to get what you want.

Caveat

Note that automatic rewrite only works if you don't use variables in proxy_pass. If you use variables, you should do rewrite yourself:

location /some_dir/ {
  rewrite    /some_dir/(.*) /$1 break;
  proxy_pass $upstream_server;
}

There are other cases where rewrite wouldn't work, that's why reading documentation is a must.

Edit

Reading your question again, it seems I may have missed that you just want to edit the html output.

For that, you can use the sub_filter directive. Something like ...

location /admin/ {
    proxy_pass http://localhost:8080/;
    sub_filter "http://your_server/" "http://your_server/admin/";
    sub_filter_once off;
}

Basically, the string you want to replace and the replacement string

Try this:

Dim colHeader(12)
colHeader = ("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L")

Unfortunately the code found online was VB.NET not VBA.

I have the same problem and I solved it and the explanation is as follow:

If the Seaborn package is not installed in anaconda, you will not be able to update it, namely, if in the Terminal we type: conda update seaborn

it will fail showing: "PackageNotFoundError: Package not found: 'seaborn' Package 'seaborn' is not installed in /Users/yifan/anaconda"

Thus we need to install seaborn in anaconda first by typing in Terminal: conda install -c https://conda.anaconda.org/anaconda seaborn

Then the seaborn will be fetched and installed in the environment of anaconda, namely in my case, /Users/yifan/anaconda

Once this installation is done, we will be able to import seaborn in python.

Side note, to check and list all discoverable environments where python is installed in anaconda, type in Terminal: conda info --envs

According to cURL docs you can also pass the certificate to the curl command:

Get a CA certificate that can verify the remote server and use the proper option to point out this CA cert for verification when connecting. For libcurl hackers: curl_easy_setopt(curl, CURLOPT_CAPATH, capath);

With the curl command line tool: --cacert [file]

For example:

curl --cacert mycertificate.cer -v https://www.stackoverflow.com

This works for me :

<style>
   .WidgetBody
        {   
            background: #F0F0F0;
            background-image:url('images/mini-loader.gif');
            background-position: 50% 50%;            
            background-repeat:no-repeat;            
        }
</style>        

Found this on HTML table: keep the same width for columns

If you set the style table-layout: fixed; on your table, you can override the browser's automatic column resizing. The browser will then set column widths based on the width of cells in the first row of the table. Change your to and remove the inside of it, and then set fixed widths for the cells in .

You may also use access in combination with opendir to determine if the directory exists, and, if the name exists, but is not a directory. For example:

/* test that dir exists (1 success, -1 does not exist, -2 not dir) */
int
xis_dir (const char *d)
{
    DIR *dirptr;

    if (access ( d, F_OK ) != -1 ) {
        // file exists
        if ((dirptr = opendir (d)) != NULL) {
            closedir (dirptr); /* d exists and is a directory */
        } else {
            return -2; /* d exists but is not a directory */
        }
    } else {
        return -1;     /* d does not exist */
    }

    return 1;
}

In WebApi 2 you can add this to global.asax

protected void Application_PostAuthorizeRequest() 
{
    System.Web.HttpContext.Current.SetSessionStateBehavior(System.Web.SessionState.SessionStateBehavior.Required);
}

Then you could access the session through:

HttpContext.Current.Session

Interactively, you can display it with

help(my_func)

Or from code you can retrieve it with

my_func.__doc__

This is asking for your MySQL username and password.

You should enter these details, which will default to "root" and "" (i.e.: nothing) if you've not specified a password.

SELECT Code,Description FROM TABLE

-- This will Include only date part of 14th March 2010. Any date with date companents will not be considered.
WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate <= DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

-- This will Include the whole day of 14th March 2010
--WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate < DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

You can get all keys in the Request.Form and then compare and get your desired values.

Your method body will look like this: -

List<int> listValues = new List<int>();
foreach (string key in Request.Form.AllKeys)
{
    if (key.StartsWith("List"))
    {
        listValues.Add(Convert.ToInt32(Request.Form[key]));
    }
}

Instead of a button, put a link and navigate it to another page

<a href="logout.php">Logout</a>

Then in logout.php page, use

session_start();
session_destroy();
header('Location: login.php');
exit;

No.

I'm going against the crowd here, but bear with me. A single JS script is intended to be effectively single threaded, but this doesn't mean that it can't be interpreted differently.

Let's say you have the following code...

var list = [];
for (var i = 0; i < 10000; i++) {
  list[i] = i * i;
}

This is written with the expectation that by the end of the loop, the list must have 10000 entries which are the index squared, but the VM could notice that each iteration of the loop does not affect the other, and reinterpret using two threads.

First thread

for (var i = 0; i < 5000; i++) {
  list[i] = i * i;
}

Second thread

for (var i = 5000; i < 10000; i++) {
  list[i] = i * i;
}

I'm simplifying here, because JS arrays are more complicated then dumb chunks of memory, but if these two scripts are able to add entries to the array in a thread-safe way, then by the time both are done executing it'll have the same result as the single-threaded version.

While I'm not aware of any VM detecting parallelizable code like this, it seems likely that it could come into existence in the future for JIT VMs, since it could offer more speed in some situations.

Taking this concept further, it's possible that code could be annotated to let the VM know what to convert to multi-threaded code.

// like "use strict" this enables certain features on compatible VMs.
"use parallel";

var list = [];

// This string, which has no effect on incompatible VMs, enables threading on
// this loop.
"parallel for";
for (var i = 0; i < 10000; i++) {
  list[i] = i * i;
}

Since Web Workers are coming to Javascript, it's unlikely that this... uglier system will ever come into existence, but I think it's safe to say Javascript is single-threaded by tradition.

You can set the horizontal alignment of ticklabels, see the example below. If you imagine a rectangular box around the rotated label, which side of the rectangle do you want to be aligned with the tickpoint?

Given your description, you want: ha='right'

n=5

x = np.arange(n)
y = np.sin(np.linspace(-3,3,n))
xlabels = ['Ticklabel %i' % i for i in range(n)]

fig, axs = plt.subplots(1,3, figsize=(12,3))

ha = ['right', 'center', 'left']

for n, ax in enumerate(axs):
    ax.plot(x,y, 'o-')
    ax.set_title(ha[n])
    ax.set_xticks(x)
    ax.set_xticklabels(xlabels, rotation=40, ha=ha[n])

Addition to @jwize's answer

Because angular.element(document).injector() was giving error injector is not defined So, I have created function that you can run after AJAX call or when DOM is changed using jQuery.

  function compileAngularElement( elSelector) {

        var elSelector = (typeof elSelector == 'string') ? elSelector : null ;  
            // The new element to be added
        if (elSelector != null ) {
            var $div = $( elSelector );

                // The parent of the new element
                var $target = $("[ng-app]");

              angular.element($target).injector().invoke(['$compile', function ($compile) {
                        var $scope = angular.element($target).scope();
                        $compile($div)($scope);
                        // Finally, refresh the watch expressions in the new element
                        $scope.$apply();
                    }]);
            }

        }

use it by passing just new element's selector. like this

compileAngularElement( '.user' ) ; 

IETF has suggested jose libs on it's wiki: http://trac.tools.ietf.org/wg/jose/trac/wiki

I would highly recommend using them for signing. I am not a Java guy, but seems like jose4j seems like a good option. Has nice examples as well: https://bitbucket.org/b_c/jose4j/wiki/JWS%20Examples

Update: jwt.io provides a neat comparison of several jwt related libraries, and their features. A must check!

I would love to hear about what other java devs prefer.

If you only need lazy loading, then you could just have a class initialisation method.

EXAMPLE_SET = False
class Example(object):
   @classmethod 
   def initclass(cls):
       global EXAMPLE_SET 
       if EXAMPLE_SET: return
       cls.the_I = 'ok'
       EXAMPLE_SET = True

   def __init__( self ):
      Example.initclass()
      self.an_i = 20

try:
    print Example.the_I
except AttributeError:
    print 'ok class not "loaded"'
foo = Example()
print foo.the_I
print Example.the_I

But the metaclass approach seems cleaner, and with more predictable behavior.

Perhaps what you're looking for is the Singleton design pattern. There's a nice SO QA about implementing shared state in Python.

change ownership

sudo chown -R $USER:$GROUP ~/.npm
sudo chown -R $USER:$GROUP ~/.config 

worked for as i installed package using sudo

$("input:radio").attr("checked",true); //for all radio inputs

or

$("your id or class here").attr("checked",true); //for unique radios

equally the same works for ("checked","checked")

There's another simple cause in case of c++.

std::thread::~thread{
    if((joinable ())
        std::terminate ();
}

i.e. scope of thread ended but you forgot to call either

thread::join();

or

thread::detach();

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

Step 1: create a MANIFEST.in file in the same folder with setup.py

Step 2: include the relative path to the files you want to add in MANIFEST.in

include README.rst
include docs/*.txt
include funniest/data.json

Step 3: set include_package_data=True in the setup() function to copy these files to site-package

Reference is here.

A simple way is to write:

-std=c++11

in the Other Options section of the compiler flags. You could do this on a per-project basis (Project -> Build Options), and/or set it as a default option in the Settings -> Compilers part.

Some projects may require -std=gnu++11 which is like C++11 but has some GNU extensions enabled.

If using g++ 4.9, you can use -std=c++14 or -std=gnu++14.

Its too late, but it may be simple and useful

var json = { "key1" : "watevr1", "key2" : "watevr2", "key3" : "watevr3" };

var index = Object.keys(json).indexOf(keytoFind);
alert(index);

http://rreddy.blogspot.com/2009/07/vncviewer-clipboard-operations-like.html

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.

To get those clipboard operations back you need to run the program "vncconfig &".

After this your clipboard actions should work fine with out any problems.

Run "vncconfig &" on the client.

Made this for a game I play, it was relevant so i'm leaving it. It's real simple. Grabs the value from platform.system. Checks it against known values for different operating systems. If it finds a match it sets the chrome path for you. If none are found it opens default browser to your link. Hope its useful to someone.

haystack.find(value => value == needle)

where haystack is an array and needle is an element in array. If element not found will be returned undefined else the same element.

try

window.frameElement.ownerDocument.domain

Another elegant one is

header("Location: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]");
exit;

The following should work. Keep single connection open all time, and just create new commands and execute them.

using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();
    using (SqlCommand command1 = new SqlCommand(commandText1, connection))
    {
    }
    using (SqlCommand command2 = new SqlCommand(commandText2, connection))
    {
    }
    // etc
}

Thanks @Joey. It's what I am looking for.

I just bring some improvements:

• to take into account multiple processes
• to avoid reaching the timeout when all processes have terminated
• to package the whole in a function

function Stop-Processes {
    param(
        [parameter(Mandatory=$true)] $processName,
                                     $timeout = 5
    )
    $processList = Get-Process $processName -ErrorAction SilentlyContinue
    if ($processList) {
        # Try gracefully first
        $processList.CloseMainWindow() | Out-Null

        # Wait until all processes have terminated or until timeout
        for ($i = 0 ; $i -le $timeout; $i ++){
            $AllHaveExited = $True
            $processList | % {
                $process = $_
                If (!$process.HasExited){
                    $AllHaveExited = $False
                }                    
            }
            If ($AllHaveExited){
                Return
            }
            sleep 1
        }
        # Else: kill
        $processList | Stop-Process -Force        
    }
}

Update the master branch, which you need to do regardless.

Then, one of:

1. Rebase the old branch against the master branch. Solve the merge conflicts during rebase, and the result will be an up-to-date branch that merges cleanly against master.

2. Merge your branch into master, and resolve the merge conflicts.

3. Merge master into your branch, and resolve the merge conflicts. Then, merging from your branch into master should be clean.

None of these is better than the other, they just have different trade-off patterns.

I would use the rebase approach, which gives cleaner overall results to later readers, in my opinion, but that is nothing aside from personal taste.

To rebase and keep the branch you would:

git checkout <branch> && git rebase <target>

In your case, check out the old branch, then

git rebase master 

to get it rebuilt against master.

targetList = list1.Concat(list2).ToList();

It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly.

You need to instantiate the view controller from the storyboard and then show it:

ViewControllerInfo* infoController = [self.storyboard instantiateViewControllerWithIdentifier:@"ViewControllerInfo"];
[self.navigationController pushViewController:infoController animated:YES];

This example assumes that you have a navigation controller in order to return to the previous view. You can of course also use presentViewController:animated:completion:. The main point is to have your storyboard instantiate your target view controller using the target view controller's ID.

Here's a solution when the docker container exits normally and you can edit the Dockerfile.

Generally, when a docker container is run, an application is served by running a command. From the Dockerfile reference,

Both CMD and ENTRYPOINT instructions define what command gets executed when running a container. ... Dockerfile should specify at least one of CMD or ENTRYPOINT commands.

When you build a image and not specify any command with CMD or ENTRYPOINT, the base image's CMD or ENTRYPOINT command would be executed.

For example, the Official Ubuntu Dockerfile has CMD ["/bin/bash"] (https://hub.docker.com/_/ubuntu). Now, the bin/bash/ command can accept input and docker run -it IMAGE_ID command attaches STDIN to the container. The result is that you get an interactive terminal and the container keeps running.

When a command with CMD or ENTRYPOINT is specified in the Dockerfile, this command gets executed when running the container. Now, if this command can finish without requiring any input, it will finish and the container will exit. docker run -it IMAGE_ID will NOT provide the interactive terminal in this case. An example would be the docker image built from the Dockerfile below-

FROM ubuntu
ENTRYPOINT echo hello 

If you need to go to the terminal of this image, you will need to keep the container running by modifying the entrypoint command.

FROM ubuntu
ENTRYPOINT echo hello && sleep infinity 

After running the container normally with docker run IMAGE_ID, you can just go to another terminal and use docker exec -it CONTAINER_ID bash to get the container's terminal.

Working with MVC websites that use jQuery, I like to make sure AJAX actions within certain event handlers can only be executed once the previous request has completed. I use a "static" jqXHR object variable to achieve this.

Given the following button:

<button type="button" onclick="ajaxAction(this, { url: '/SomeController/SomeAction' })">Action!</button>

I generally use an IIFE like this for my click handler:

var ajaxAction = (function (jqXHR) {
    return function (sender, args) {
        if (!jqXHR || jqXHR.readyState == 0 || jqXHR.readyState == 4) {
            jqXHR = $.ajax({
                url: args.url,
                type: 'POST',
                contentType: 'application/json',
                data: JSON.stringify($(sender).closest('form').serialize()),
                success: function (data) {
                    // Do something here with the data.
                }
            });
        }
    };
})(null);

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

You should use gnuplot and be sure to issue the command "set term dumb" after starting up. You can also give a row and column count. Here is the output from gnuplot if you issue "set term dumb 64 10" and then "plot sin(x)":

 

    1 ++-----------****-----------+--***-------+------****--++
  0.6 *+          **+  *          +**   *      sin(x)*******++
  0.2 +*         *      *         **     **         *     **++
    0 ++*       **       *       **       *       **       *++
 -0.4 ++**     *         **     **         *      *         *+

     -10           -5             0            5             10

It looks better at 79x24 (don't use the 80th column on an 80x24 display: some curses implementations don't always behave well around the last column).

I'm using gnuplot v4, but this should work on slightly older or newer versions.

If you decide to use Underscore.js you better do

_.values(ahash)[0]

to get value, or

_.keys(ahash)[0]

to get key.

Just try with

$("._statusDDL").val("2");

and not with

$("._statusDDL").val(2);

Replace

char *str = "hello";

with

char *str = (char*)"hello";

or if you are calling in function:

foo("hello");

replace this with

foo((char*) "hello");

The difference is as follows:

Public :: A public variable or method can be accessed directly by any user of the class.

Protected :: A protected variable or method cannot be accessed by users of the class but can be accessed inside a subclass that inherits from the class.

Private :: A private variable or method can only be accessed internally from the class in which it is defined.This means that a private variable or method cannot be called from a child that extends the class.

The first line of a paragraph is indented by default, thus whether or not you have \indent there won't make a difference. \indent and \noindent can be used to override default behavior. You can see this by replacing your line with the following:

Now we are engaged in a great civil war.\\
\indent this is indented\\
this isn't indented


\noindent override default indentation (not indented)\\

C-style solution could be to use itoa, but better way is to print this number into string by using sprintf / snprintf. Check this question: How to convert an integer to a string portably?

Note that itoa function is not defined in ANSI-C and is not part of C++, but is supported by some compilers. It's a non-standard function, thus you should avoid using it. Check this question too: Alternative to itoa() for converting integer to string C++?

Also note that writing C-style code while programming in C++ is considered bad practice and sometimes referred as "ghastly style". Do you really want to convert it into C-style char* string? :)

Posting your HTML might help a bit. Instead, you can get the element first and then check if it is null or not and then ask for its value rather than just asking for the value directly without knowing if the element is visible on the HTML or not.

element1 = document.getElementById(id);

if(element1 != null)
{
    //code to set the value variable.
}

A variation on Praveenkumar_V's post:

SELECT `name` FROM mysql.proc WHERE db = 'dbname' AND `type` = 'PROCEDURE';
SELECT `name` FROM mysql.proc WHERE db = 'dbname' AND `type` = 'FUNCTION';

..and this because I needed to save time after some housekeeping:

SELECT CONCAT(
     "GRANT EXECUTE ON PROCEDURE `"
    ,`name`
    ,"` TO username@'%'; -- "
    ,`comment`
)
FROM mysql.proc
WHERE db = 'dbname'
AND `type` = 'PROCEDURE';

SELECT CONCAT(
     "GRANT EXECUTE ON FUNCTION `"
    ,`name`
    ,"` TO username@'%'; -- "
    ,`comment`
)
FROM mysql.proc
WHERE db = 'dbname'
AND `type` = 'FUNCTION';

The database uses the same lock for all #temp tables so if you are using a lot you will get deadlock problems. It is better to use @ table variables for concurrency.

Since Django 1.8 released, you can use from_db classmethod to cache old value of remote_image. Then in save method you can compare old and new value of field to check if the value has changed.

@classmethod
def from_db(cls, db, field_names, values):
    new = super(Alias, cls).from_db(db, field_names, values)
    # cache value went from the base
    new._loaded_remote_image = values[field_names.index('remote_image')]
    return new

def save(self, force_insert=False, force_update=False, using=None,
         update_fields=None):
    if (self._state.adding and self.remote_image) or \
        (not self._state.adding and self._loaded_remote_image != self.remote_image):
        # If it is first save and there is no cached remote_image but there is new one, 
        # or the value of remote_image has changed - do your stuff!

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

use doesn't include anything. It just imports the specified namespace (or class) to the current scope

If you want the classes to be autoloaded - read about autoloading

You can do it with a separate UPDATE statement

UPDATE report.TEST target
SET    is Deleted = 'Y'
WHERE  NOT EXISTS (SELECT 1
                   FROM   main.TEST source
                   WHERE  source.ID = target.ID);

I don't know of any way to integrate this into your MERGE statement.

Take a look at the java.text.MessageFormat class, MessageFormat takes a set of objects, formats them, then inserts the formatted strings into the pattern at the appropriate places.

Object[] params = new Object[]{"hello", "!"};
String msg = MessageFormat.format("{0} world {1}", params);

The above solutions work fine for most cases. However, if you also need to remove all traces of that file (ie sensitive data such as passwords), you will also want to remove it from your entire commit history, as the file could still be retrieved from there.

Here is a solution that removes all traces of the file from your entire commit history, as though it never existed, yet keeps the file in place on your system.

You can actually skip to step 3 if you are in your local git repository, and don't need to perform a dry run. In my case, I only needed steps 3 and 6, as I had already created my .gitignore file, and was in the repository I wanted to work on.

To see your changes, you may need to go to the GitHub root of your repository and refresh the page. Then navigate through the links to get to an old commit that once had the file, to see that it has now been removed. For me, simply refreshing the old commit page did not show the change.

It looked intimidating at first, but really, was easy and worked like a charm ! :-)

As other users said, the best way for Windows users is to set the global environment variable.

I install the Miniconda3 for MXNet.

Before I do something, only Anaconda Prompt works for conda.

After setting the global environment variable, The CMD and Git Bash work. But in some IDEs like RStudio, the nested Git Bash doesn't work.

After restarting my computer, the Git Bash in the RStudio works for conda.

I hope these tests helps for you.

I would say "Yes". As "Matz" had said something like this in one of his talks, "Ruby objects have no types." Not all of it but the part that he is trying to get across to us. Why would anyone have said "Everything is an Object" then? To add he said "Data has Types not objects".

So we might enjoy this.

https://www.youtube.com/watch?v=1l3U1X3z0CE

But Ruby doesn't care to much about the type of object just the class. We use classes not types. All data then has a class.

12345.class

'my string'.class

They may also have ancestors

Object.ancestors

They also have meta classes but I'll save you the details on that.

Once you know the class then you'll be able to lookup what methods you may use for it. That's where the "data type" is needed. If you really want to get into details the look up...

"The Ruby Object Model"

This is the term used for how Ruby handles objects. It's all internal so you don't really see much of this but it's nice to know. But that's another topic.

Yes! The class is the data type. Objects have classes and data has types. So if you know about data bases then you know there are only a finite set of types.

text blocks numbers

The Oracle/PLSQL CONCAT function allows to concatenate two strings together.

CONCAT( string1, string2 )

string1

The first string to concatenate.

string2

The second string to concatenate.

E.g.

SELECT 'I like ' || type_column_name || ' cake with ' || 
icing_column_name || ' and a ' fruit_column_name || '.' 
AS Cake FROM table;

try something like

background: url(bgimage.jpg) no-repeat;
background-size: 100%;

First check the variables declared using proper Datatypes. I had a same problem then I have checked, by mistake I declared SAPUser as int datatype so that the error occurred. One more thing XML file stores its data using concept like array but its first index starts having +1. e.g. if error is in(7,2) then check for 6th line always.....

 function uploadFile() {
     var fileElement = document.getElementById("fileToUpload");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension == "odx-d"||fileExtension == "odx"||fileExtension == "pdx"||fileExtension == "cmo"||fileExtension == "xml") {
         var fd = new FormData();
        fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
        var xhr = new XMLHttpRequest();
        xhr.upload.addEventListener("progress", uploadProgress, false);
        xhr.addEventListener("load", uploadComplete, false);
        xhr.addEventListener("error", uploadFailed, false);
        xhr.addEventListener("abort", uploadCanceled, false);
        xhr.open("POST", "/post_uploadReq");
        xhr.send(fd);
        }
        else {
            alert("You must select a valid odx,pdx,xml or cmo file for upload");
            return false;
        }
       
      }

tried this , works very well

Use LinearLayout.LayoutParams instead of MarginLayoutParams. Here's the documentation.

you can use Dependency Walker to view the function name. you can see the function's parameters only if it's decorated. read the following from the FAQ:

How do I view the parameter and return types of a function? For most functions, this information is simply not present in the module. The Windows' module file format only provides a single text string to identify each function. There is no structured way to list the number of parameters, the parameter types, or the return type. However, some languages do something called function "decoration" or "mangling", which is the process of encoding information into the text string. For example, a function like int Foo(int, int) encoded with simple decoration might be exported as _Foo@8. The 8 refers to the number of bytes used by the parameters. If C++ decoration is used, the function would be exported as ?Foo@@YGHHH@Z, which can be directly decoded back to the function's original prototype: int Foo(int, int). Dependency Walker supports C++ undecoration by using the Undecorate C++ Functions Command.

In Laravel 5.4 we can't call ip static. This a correct way to get the IP of the user:

 use Illuminate\Http\Request;

public function contactUS(Request $request)
    {
        echo $request->ip();
        return view('page.contactUS');
    }

I actually found it better just testing for string length since many times the field is not null, just empty

<xsl:when test="string-length(field-you-want-to-test)<1">

You should also be aware of the fact, that with utf8_general_ci when using a varchar field as unique or primary index inserting 2 values like 'a' and 'á' would give a duplicate key error.

Replace following

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

With

curl_setopt ($ch, CURLOPT_SSLVERSION, 6);

Should work flawlessly.

If NEW_TABLE already exists then ...

insert into new_table 
select * from old_table
/

If you want to create NEW_TABLE based on the records in OLD_TABLE ...

create table new_table as 
select * from old_table
/

If the purpose is to create a new but empty table then use a WHERE clause with a condition which can never be true:

create table new_table as 
select * from old_table
where 1 = 2
/

Remember that CREATE TABLE ... AS SELECT creates only a table with the same projection as the source table. The new table does not have any constraints, triggers or indexes which the original table might have. Those still have to be added manually (if they are required).

This might help you guys.(I've applied this to my Projects)

Here's the 3 easy steps.

1. Go to your Solution Explorer. Look for .edmx file (Usually found on root level)
2. Open that .edmx file, a Model Diagram window appears. Right click anywhere on that window and select "Update Model from Database". An Update Wizard window appears. Click Finish to update your model.
3. Save that .edmx file.

That's it. It will sync/refresh your Model base on the changes on your database.

On a Spanish keyboard it is CTRL + ¿ (or CTRL + ¡).

In our case we had a query which loads multiple items with select * from x where something in (...) The in part was so long for benchmark test.(17mb as text query). Query is valid but text so long. Shortening the query solved the problem.

simple answer:

5 + '' + 6;

Either modify the pattern beforehand so that it only matches the entire string:

var r = /^a$/

or check afterward whether the pattern matched the whole string:

function matchExact(r, str) {
   var match = str.match(r);
   return match && str === match[0];
}

It's not pretty but it's the least confusing way to add whitespace I've found and it gives me absolute control over how much whitespace I add.

It's easy to identify exactly what I'm trying to do here when I come back to the code weeks later.

In general, multiple inserts will be slower because of the connection overhead. Doing multiple inserts at once will reduce the cost of overhead per insert.

Depending on which language you are using, you can possibly create a batch in your programming/scripting language before going to the db and add each insert to the batch. Then you would be able to execute a large batch using one connect operation. Here's an example in Java.

Thats what i am using try it.

<a href="index.php"><button style ="position:absolute;top:450px;left:1100px;height:30px;width:200px;"> Cancel </button></a>

Also, you should remember that if you run your web server at non-standard port you need to include port number at base href too:

<base href="//localhost:1234" />  // from base url
<base href="../" />  // for one step above

As stated, use TextView.setText(Html.fromHtml(String))

And use these tags in your Html formatted string:

Classically, ~/.profile is used by Bourne Shell, and is probably supported by Bash as a legacy measure. Again, ~/.login and ~/.cshrc were used by C Shell - I'm not sure that Bash uses them at all.

The ~/.bash_profile would be used once, at login. The ~/.bashrc script is read every time a shell is started. This is analogous to /.cshrc for C Shell.

One consequence is that stuff in ~/.bashrc should be as lightweight (minimal) as possible to reduce the overhead when starting a non-login shell.

I believe the ~/.environment file is a compatibility file for Korn Shell.

new Date().toString("yyyyMMddHHmmss").
      replace(/T/, ' ').  
      replace(/\..+/, '') 

with .toString(), This becomes in format

replace(/T/, ' '). //replace T to ' ' 2017-01-15T...

replace(/..+/, '') //for ...13:50:16.1271

example, see var date and hour:

var date="2017-01-15T13:50:16.1271".toString("yyyyMMddHHmmss")._x000D_
                    replace(/T/, ' ').      _x000D_
                    replace(/\..+/, '');_x000D_
    _x000D_
                    var auxCopia=date.split(" ");_x000D_
                    date=auxCopia[0];_x000D_

If you plan on constructing HashMaps with variable depth, use a recursive data structure.

Below is an implementation providing a sample interface:

class NestedMap<K, V> {

    private final HashMap<K, NestedMap> child;
    private V value;

    public NestedMap() {
        child = new HashMap<>();
        value = null;
    }

    public boolean hasChild(K k) {
        return this.child.containsKey(k);
    }

    public NestedMap<K, V> getChild(K k) {
        return this.child.get(k);
    }

    public void makeChild(K k) {
        this.child.put(k, new NestedMap());
    }

    public V getValue() {
        return value;
    }

    public void setValue(V v) {
        value = v;
    }
}

and example usage:

class NestedMapIllustration {
    public static void main(String[] args) {

        NestedMap<Character, String> m = new NestedMap<>();

        m.makeChild('f');
        m.getChild('f').makeChild('o');
        m.getChild('f').getChild('o').makeChild('o');
        m.getChild('f').getChild('o').getChild('o').setValue("bar");

        System.out.println(
            "nested element at 'f' -> 'o' -> 'o' is " +
            m.getChild('f').getChild('o').getChild('o').getValue());
    }
}

First make your data base offline after that detach it e.g.

Use Master
GO
ALTER DATABASE dbname SET OFFLINE
GO
EXEC sp_detach_db 'dbname', 'true'

Something like...

DateTime today = new DateTime();
DateTime yesterday = today.minusDays(1);

Duration duration = new Duration(yesterday, today);
System.out.println(duration.getStandardDays());
System.out.println(duration.getStandardHours());
System.out.println(duration.getStandardMinutes());

Which outputs

1
24
1440

or

System.out.println(Minutes.minutesBetween(yesterday, today).getMinutes());

Which is probably more what you're after

You have to do it like this:

If strMyString.Contains("Something") OrElse strMyString.Contains("Something2") Then
    '[Put Code Here]

In LINQ you could do something like:

foreach (var data in from DataRow row in dataTable.Rows
                     from DataColumn col in dataTable.Columns
                          where
                              row[col] != null
                          select row[col])
{
    // do something with data
}

Never, you can't do it since package name is the unique name Identifier for your app.....

If you're running into this issue despite trying all of the solutions in this thread, and you're connecting to the service via SSL (e.g. https), this might help:

http://forums.newatlanta.com/messages.cfm?threadid=554611A2-E03F-43DB-92F996F4B6222BC0&#top

To summarize (in case the link dies in the future), if your requests are large enough the certificate negotiation between the client and the service will fail randomly. To keep this from happening, you'll need to enable a certain setting on your SSL bindings. From your IIS server, here are the steps you'll need to take:

1. Via cmd or powershell, run netsh http show sslcert. This will give you your current configuration. You'll want to save this somehow so you can reference it again later.
2. You should notice that "Negotiate Client Certificate" is disabled. This is the problem setting; the following steps will demonstrate how to enable it.
3. Unfortunately there is no way to change existing bindings; you'll have to delete it and re-add it. Run netsh http delete sslcert <ipaddress>:<port> where <ipaddress>:<port> is the IP:port shown in the configuration you saved earlier.
4. Now you can re-add the binding. You can view the valid parameters for netsh http add sslcert here (MSDN) but in most cases your command will look like this:

netsh http add sslcert ipport=<ipaddress>:<port> appid=<application ID from saved config including the {}> certhash=<certificate hash from saved config> certstorename=<certificate store name from saved config> clientcertnegotiation=enable

If you have multiple SSL bindings, you'll repeat the process for each of them. Hopefully this helps save someone else the hours and hours of headache this issue caused me.

EDIT: In my experience, you can't actually run the netsh http add sslcert command from the command line directly. You'll need to enter the netsh prompt first by typing netsh and then issue your command like http add sslcert ipport=... in order for it to work.

Do you want to do this?

SELECT id, parent_id, name, 
 (select Name from tbl where id = t.parent_id) parent_name
FROM tbl t start with id = 1 CONNECT BY PRIOR id = parent_id

Edit Another option based on OMG's one (but I think that will perform equally):

select 
           t1.id, 
           t1.parent_id, 
           t1.name,
           t2.name AS parent_name,
           t2.id AS parent_id
from 
    (select id, parent_id, name
    from tbl
    start with id = 1 
    connect by prior id = parent_id) t1
    left join
    tbl t2 on t2.id = t1.parent_id

I also faced the similar issues, changing the version from 2.0.0.RELEASE to 1.5.10.RELEASE worked for me, please try it before downgrading the maven version

The first version will add a new KeyValuePair to the dictionary, throwing if key is already in the dictionary. The second, using the indexer, will add a new pair if the key doesn't exist, but overwrite the value of the key if it already exists in the dictionary.

IDictionary<string, string> strings = new Dictionary<string, string>();

strings["foo"] = "bar";          //strings["foo"] == "bar"
strings["foo"] = string.Empty;   //strings["foo"] == string.empty
strings.Add("foo", "bar");       //throws     

You may try this:

public static void main(String[] args) {
    BigDecimal a = new BigDecimal("10.12345");
    System.out.println(toPrecision(a, 2));
}

private static BigDecimal toPrecision(BigDecimal dec, int precision) {
    String plain = dec.movePointRight(precision).toPlainString();
    return new BigDecimal(plain.substring(0, plain.indexOf("."))).movePointLeft(precision);
}

OUTPUT:

You could split the problem up into two pieces:

1. Some kind of search algorithm that will enumerate possible strings in the grid.
2. A way of testing whether a string is a valid word.

Ideally, (2) should also include a way of testing whether a string is a prefix of a valid word – this will allow you to prune your search and save a whole heap of time.

Adam Rosenfield's Trie is a solution to (2). It's elegant and probably what your algorithms specialist would prefer, but with modern languages and modern computers, we can be a bit lazier. Also, as Kent suggests, we can reduce our dictionary size by discarding words that have letters not present in the grid. Here's some python:

def make_lookups(grid, fn='dict.txt'):
    # Make set of valid characters.
    chars = set()
    for word in grid:
        chars.update(word)

    words = set(x.strip() for x in open(fn) if set(x.strip()) <= chars)
    prefixes = set()
    for w in words:
        for i in range(len(w)+1):
            prefixes.add(w[:i])

    return words, prefixes

Wow; constant-time prefix testing. It takes a couple of seconds to load the dictionary you linked, but only a couple :-) (notice that words <= prefixes)

Now, for part (1), I'm inclined to think in terms of graphs. So I'll build a dictionary that looks something like this:

graph = { (x, y):set([(x0,y0), (x1,y1), (x2,y2)]), }

i.e. graph[(x, y)] is the set of coordinates that you can reach from position (x, y). I'll also add a dummy node None which will connect to everything.

Building it's a bit clumsy, because there's 8 possible positions and you have to do bounds checking. Here's some correspondingly-clumsy python code:

def make_graph(grid):
    root = None
    graph = { root:set() }
    chardict = { root:'' }

    for i, row in enumerate(grid):
        for j, char in enumerate(row):
            chardict[(i, j)] = char
            node = (i, j)
            children = set()
            graph[node] = children
            graph[root].add(node)
            add_children(node, children, grid)

    return graph, chardict

def add_children(node, children, grid):
    x0, y0 = node
    for i in [-1,0,1]:
        x = x0 + i
        if not (0 <= x < len(grid)):
            continue
        for j in [-1,0,1]:
            y = y0 + j
            if not (0 <= y < len(grid[0])) or (i == j == 0):
                continue

            children.add((x,y))

This code also builds up a dictionary mapping (x,y) to the corresponding character. This lets me turn a list of positions into a word:

def to_word(chardict, pos_list):
    return ''.join(chardict[x] for x in pos_list)

Finally, we do a depth-first search. The basic procedure is:

1. The search arrives at a particular node.
2. Check if the path so far could be part of a word. If not, don't explore this branch any further.
3. Check if the path so far is a word. If so, add to the list of results.
4. Explore all children not part of the path so far.

Python:

def find_words(graph, chardict, position, prefix, results, words, prefixes):
    """ Arguments:
      graph :: mapping (x,y) to set of reachable positions
      chardict :: mapping (x,y) to character
      position :: current position (x,y) -- equals prefix[-1]
      prefix :: list of positions in current string
      results :: set of words found
      words :: set of valid words in the dictionary
      prefixes :: set of valid words or prefixes thereof
    """
    word = to_word(chardict, prefix)

    if word not in prefixes:
        return

    if word in words:
        results.add(word)

    for child in graph[position]:
        if child not in prefix:
            find_words(graph, chardict, child, prefix+[child], results, words, prefixes)

Run the code as:

grid = ['fxie', 'amlo', 'ewbx', 'astu']
g, c = make_graph(grid)
w, p = make_lookups(grid)
res = set()
find_words(g, c, None, [], res, w, p)

and inspect res to see the answers. Here's a list of words found for your example, sorted by size:

 ['a', 'b', 'e', 'f', 'i', 'l', 'm', 'o', 's', 't',
 'u', 'w', 'x', 'ae', 'am', 'as', 'aw', 'ax', 'bo',
 'bu', 'ea', 'el', 'em', 'es', 'fa', 'ie', 'io', 'li',
 'lo', 'ma', 'me', 'mi', 'oe', 'ox', 'sa', 'se', 'st',
 'tu', 'ut', 'wa', 'we', 'xi', 'aes', 'ame', 'ami',
 'ase', 'ast', 'awa', 'awe', 'awl', 'blo', 'but', 'elb',
 'elm', 'fae', 'fam', 'lei', 'lie', 'lim', 'lob', 'lox',
 'mae', 'maw', 'mew', 'mil', 'mix', 'oil', 'olm', 'saw',
 'sea', 'sew', 'swa', 'tub', 'tux', 'twa', 'wae', 'was',
 'wax', 'wem', 'ambo', 'amil', 'amli', 'asem', 'axil',
 'axle', 'bleo', 'boil', 'bole', 'east', 'fame', 'limb',
 'lime', 'mesa', 'mewl', 'mile', 'milo', 'oime', 'sawt',
 'seam', 'seax', 'semi', 'stub', 'swam', 'twae', 'twas',
 'wame', 'wase', 'wast', 'weam', 'west', 'amble', 'awest',
 'axile', 'embox', 'limbo', 'limes', 'swami', 'embole',
 'famble', 'semble', 'wamble']

The code takes (literally) a couple of seconds to load the dictionary, but the rest is instant on my machine.

In VS2019, the project property page, TypeScript Build tab has a setting (dropdown) for "Module System". When I changed that from "ES2015" to CommonJS, then VS2019 IDE stopped complaining that it could find neither axios nor redux-thunk (TS2307).

Another thing to notice is you are trying to convert a date in mm/dd/yyyy but if you have any plans of comparing this converted date to some other date then make sure to convert it in yyyy-mm-dd format only since to_char literally converts it into a string and with any other format we will get undesired result. For any more explanation follow this: Comparing Dates in Oracle SQL

A small variation on the accepted answer. toFixed(2) returns a string, and you will always get two decimal places. These might be zeros. If you would like to suppress final zero(s), simply do this:

var discount = + ((price / listprice).toFixed(2));

Edited: I've just discovered what seems to be a bug in Firefox 35.0.1, which means that the above may give NaN with some values.
I've changed my code to

var discount = Math.round(price / listprice * 100) / 100;

This gives a number with up to two decimal places. If you wanted three, you would multiply and divide by 1000, and so on.
The OP wants two decimal places always, but if toFixed() is broken in Firefox it needs fixing first.
See https://bugzilla.mozilla.org/show_bug.cgi?id=1134388

You can remove them from /Library/Developer/CoreSimulator/Profiles/Runtimes (Not ~/Library!):

Mutex is used to protect the sensitive code and data, semaphore is used to synchronization.You also can have practical use with protect the sensitive code, but there might be a risk that release the protection by the other thread by operation V.So The main difference between bi-semaphore and mutex is the ownership.For instance by toilet , Mutex is like that one can enter the toilet and lock the door, no one else can enter until the man get out, bi-semaphore is like that one can enter the toilet and lock the door, but someone else could enter by asking the administrator to open the door, it's ridiculous.

Also iftop:

display bandwidth usage on an interface

iftop does for network usage what top(1) does for CPU usage. It listens to network traffic on a named interface and displays a table of current bandwidth usage by pairs of hosts. Handy for answering the question "why is our ADSL link so slow?"...

datejs could parse following, you might want to try out.

Date.parse('1997-07-16T19:20:15')           // ISO 8601 Formats
Date.parse('1997-07-16T19:20:30+01:00')     // ISO 8601 with Timezone offset

Edit: Regex version

x = "2011-01-28T19:30:00EST"

MM = ["January", "February","March","April","May","June","July","August","September","October","November", "December"]

xx = x.replace(
    /(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):\d{2}(\w{3})/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$2-1]+" "+$3+", "+$1+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6
    }
)

Result

January 28, 2011 - 7:30PM EST

Edit2: I changed my timezone to EST and now I got following

x = "2011-01-28T19:30:00-05:00"

MM = {Jan:"January", Feb:"February", Mar:"March", Apr:"April", May:"May", Jun:"June", Jul:"July", Aug:"August", Sep:"September", Oct:"October", Nov:"November", Dec:"December"}

xx = String(new Date(x)).replace(
    /\w{3} (\w{3}) (\d{2}) (\d{4}) (\d{2}):(\d{2}):[^(]+\(([A-Z]{3})\)/,
    function($0,$1,$2,$3,$4,$5,$6){
        return MM[$1]+" "+$2+", "+$3+" - "+$4%12+":"+$5+(+$4>12?"PM":"AM")+" "+$6 
    }
)

return

January 28, 2011 - 7:30PM EST

Basically

I'am using VisualStdio 2008. In this case I often set Preprocessor Definitions

Menu \ Project \ [ProjectName] Properties... Alt+F7

If click this menu or press Alt + F7 in project window, you can see "Property Pages" window.

Then see menu on left of window.

Configuration Properties \ C/C++ \ Preprocessor

Then add _CRT_SECURE_NO_WARNINGS to \ Preprocessor Definitions.

This is a divitis-esque solution which nontheless should work for all browsers...

The markup is as follows and needs to be inside something with relative positioning (and its width should be set, for example 400 pixels):

<div class="hide-scrollbar">
    <div class="scrollbar">
        <div class="scrollbar-inner">

        </div>
    </div>
</div>

The CSS:

.hide-scrollbar {
    overflow: hidden;
    position: absolute;
    top: 0;
    left: 0;
    right: 0;
    bottom: 0;
}

.scrollbar {
    overflow-y: scroll;
    position: absolute;
    top: 0;
    left: 0;
    right: -50px;
    bottom: 0;
}

.scrollbar-inner {
    width: 400px;
}

When is a github repository not empty, like .gitignore and license

Use pull --allow-unrelated-histories and push --force-with-lease

Use commands

git init
git add .
git commit -m "initial commit"
git remote add origin https://github.com/...
git pull origin master --allow-unrelated-histories
git push --force-with-lease

Exact transfer to Angular2+ is as below:

<button (click)="myFunc()"></button>

also in your component file:

import { Component, OnInit } from "@angular/core";

@Component({
  templateUrl:"button.html" //this is the component which has the above button html
})

export class App implements OnInit{
  constructor(){}

  ngOnInit(){

  }

  myFunc(){
    console.log("function called");
  }
}

Please try:

SELECT * INTO NewTable FROM OldTable

Vectors and matrices can only be of a single type and cbind and rbind on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.

(Note that in your rbind example, the promotion happens within the c call:

> c(10, "[]", "[[1,2]]")
[1] "10"      "[]"      "[[1,2]]"

If you want a rectangular structure where the columns can be different types, you want a data.frame. Any of the following should get you what you want:

> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
  v1 v2      v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ v1: num  10 20
 $ v2: Factor w/ 1 level "[]": 1 1
 $ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using specifically the data.frame version of cbind)

> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c(10, 20)              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using cbind, but making the first a data.frame so that it combines as data.frames do):

> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c.10..20.              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

With a statistical profiler like austin, no instrumentation is required, meaning that you can get profiling data out of a Python application simply with

austin python3 my_script.py

The raw output isn't very useful, but you can pipe that to flamegraph.pl to get a flame graph representation of that data that gives you a breakdown of where the time (measured in microseconds of real time) is being spent.

remove mysql :

sudo apt -y purge mysql*

Restart instance :

When your path starts with a root dir i.e. C:\ in windows or / in Unix or in java resources path, it is considered to be an absolute path. Everything else is relative, so

new File("test.txt") is the same as new File("./test.txt")

new File("test/../test.txt") is the same as new File("./test/../test.txt")

The major difference between getAbsolutePath and getCanonicalPath is that the first one concatenates a parent and a child path, so it may contain dots: .. or .. getCanonicalPath will always return the same path for a particular file.

Note: File.equals uses an abstract form of a path (getAbsolutePath) to compare files, so this means that two File objects for the same might not be equal and Files are unsafe to use in collections like Map or Set.

It looks like the machine you're trying to run this on has only 256 MB memory.

Maybe the JVM tries to allocate a large, contiguous block of 64 MB memory. The 192 MB that you have free might be fragmented into smaller pieces, so that there is no contiguous block of 64 MB free to allocate.

Try starting your Java program with a smaller heap size, for example:

java -Xms16m ...

private void deleteFileOrFolder(File file){
    try {
        for (File f : file.listFiles()) {
            f.delete();
            deleteFileOrFolder(f);
        }
    } catch (Exception e) {
        e.printStackTrace(System.err);
    }
}

Here is an example of the Microsoft Queue object wrapped so all actions against it are thread safe.

I hope this example helps. Remember this is bare bones. Using these basic ideas you can safely harness the power of threads.

public class WorkState
{
    private readonly Object _Lock = new Object();
    private Int32 _State;

    public Int32 GetState()
    {
        lock (_Lock)
        {
            return _State;
        }
    }

    public void UpdateState()
    {
        lock (_Lock)
        {
            _State++;   
        }   
    }
}

public class Worker
{
    private readonly WorkState _State;
    private readonly Thread _Thread;
    private volatile Boolean _KeepWorking;

    public Worker(WorkState state)
    {
        _State = state;
        _Thread = new Thread(DoWork);
        _KeepWorking = true;                
    }

    public void DoWork()
    {
        while (_KeepWorking)
        {
            _State.UpdateState();                   
        }
    }

    public void StartWorking()
    {
        _Thread.Start();
    }

    public void StopWorking()
    {
        _KeepWorking = false;
    }
}



private void Execute()
{
    WorkState state = new WorkState();
    Worker worker = new Worker(state);

    worker.StartWorking();

    while (true)
    {
        if (state.GetState() > 100)
        {
            worker.StopWorking();
            break;
        }
    }                   
}

Using the print '%q' technique, we can run a loop to find out which characters are special:

#!/bin/bash
special=$'`!@#$%^&*()-_+={}|[]\\;\':",.<>?/ '
for ((i=0; i < ${#special}; i++)); do
    char="${special:i:1}"
    printf -v q_char '%q' "$char"
    if [[ "$char" != "$q_char" ]]; then
        printf 'Yes - character %s needs to be escaped\n' "$char"
    else
        printf 'No - character %s does not need to be escaped\n' "$char"
    fi
done | sort

It gives this output:

No, character % does not need to be escaped

Shortly after finding this questions I found these examples on CSS Tricks: http://css-tricks.com/examples/ShapesOfCSS/

Copied so you don't have to click

.square {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background: red;_x000D_
}_x000D_
.circle {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  background: red;_x000D_
  -moz-border-radius: 50px;_x000D_
  -webkit-border-radius: 50px;_x000D_
  border-radius: 50px;_x000D_
}_x000D_
/* Cleaner, but slightly less support: use "50%" as value */

<div class="square"></div>_x000D_
<div class="circle"></div>

There are many other shape examples in the above link, but you will have to test for browser compatibility.

In my case it was the wrong dependecy for CrudRepository. My IDE added also follwing:

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
        <version>1.11.2.RELEASE</version>
    </dependency>

But I just needed:

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

I removed the first one and everything was fine.

Great question. There are three solutions I know about:

Solution #1

Replace the default widget.

class SearchForm(forms.Form):  
    q = forms.CharField(
            label='Search',
            widget=forms.TextInput(attrs={'placeholder': 'Search'})
        )

Solution #2

Customize the default widget. If you're using the same widget that the field usually uses then you can simply customize that one instead of instantiating an entirely new one.

class SearchForm(forms.Form):  
    q = forms.CharField(label='Search')

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['q'].widget.attrs.update({'placeholder': 'Search'})

Solution #3

Finally, if you're working with a model form then (in addition to the previous two solutions) you have the option to specify a custom widget for a field by setting the widgets attribute of the inner Meta class.

class CommentForm(forms.ModelForm):  
    class Meta:
        model = Comment
        widgets = {
            'body': forms.Textarea(attrs={'cols': 80, 'rows': 20})
        }

In programmatically, add the background image

minSdkVersion 16

RadioGroup rg = new RadioGroup(this);
RadioButton radioButton = new RadioButton(this);
radioButton.setBackground(R.drawable.account_background);
rg.addView(radioButton);

Simple! You must only acept request, on your phone.

T = map(lambda i: L[i], Idx)

# Pygame Example  

import pygame, sys  
from pygame.locals import *

pygame.init()  
DISPLAYSURF = pygame.display.set_mode((400, 300))  
pygame.display.set_caption('IBM Emulator')

BLACK = (0, 0, 0)  
GREEN = (0, 255, 0)

fontObj = pygame.font.Font('freesansbold.ttf', 32)  
textSurfaceObj = fontObj.render('IBM PC Emulator', True, GREEN,BLACK)  
textRectObj = textSurfaceObj.get_rect()  
textRectObj = (10, 10)

try:  
    while True: # main loop  
        DISPLAYSURF.fill(BLACK)  
        DISPLAYSURF.blit(textSurfaceObj, textRectObj)  
        for event in pygame.event.get():  
            if event.type == QUIT:  
                pygame.quit()  
                sys.exit()  
        pygame.display.update()  
except SystemExit:  
    pass

In Windows, open a terminal, go to the content folder and write:

copy /b *.sql all_files.sql

This concate all files in only one, making it really quick to import with PhpMyAdmin.

In Linux and macOS, as @BlackCharly pointed out, this will do the trick:

cat *.sql  > .all_files.sql

Important Note: Doing it directly should go well, but it could end up with you stuck in a loop with a massive output file getting bigger and bigger due to the system adding the file to itself. To avoid it, two possible solutions.

A) Put the result in a separate directory to be safe (Thanks @mosh):

mkdir concatSql
cat *.sql  > ./concatSql/all_files.sql

B) Concat them in a file with a different extension and then change it the name. (Thanks @William Turrell)

cat *.sql  > all_files.sql1
mv all_files.sql1 all_files.sql

One other thing that can cause "ambiguous redirect" is \t \n \r in the variable name you are writing too

Maybe not \n\r? But err on the side of caution

Try this

echo "a" > ${output_name//[$'\t\n\r']}

I got hit with this one while parsing HTML, Tabs \t at the beginning of the line.

Edit: I had first said:

What's inelegant about the dictionary solution. It seems perfectly elegant to me, esp since you only need to set the comparator in creation of the dictionary.

Of course though, it is inelegant to use something as a key when it's also the value.

Therefore I would use a HashSet. If later operations required indexing, I'd create a list from it when the Adding was done, otherwise, just use the hashset.

Give a different alias

SELECT  Convert(varchar,A.InsertDate,103) as converted_Tran_Date from table as A
order by A.InsertDate 

It is used to find the how many rows contain data in a worksheet that contains data in the column "A". The full usage is

 lastRowIndex = ws.Cells(ws.Rows.Count, "A").End(xlUp).row

Where ws is a Worksheet object. In the questions example it was implied that the statement was inside a With block

With ws
    lastRowIndex = .Cells(.Rows.Count, "A").End(xlUp).row
End With

1. ws.Rows.Count returns the total count of rows in the worksheet (1048576 in Excel 2010).
2. .Cells(.Rows.Count, "A") returns the bottom most cell in column "A" in the worksheet

Then there is the End method. The documentation is ambiguous as to what it does.

Returns a Range object that represents the cell at the end of the region that contains the source range

Particularly it doesn't define what a "region" is. My understanding is a region is a contiguous range of non-empty cells. So the expected usage is to start from a cell in a region and find the last cell in that region in that direction from the original cell. However there are multiple exceptions for when you don't use it like that:

• If the range is multiple cells, it will use the region of rng.cells(1,1).
• If the range isn't in a region, or the range is already at the end of the region, then it will travel along the direction until it enters a region and return the first encountered cell in that region.
• If it encounters the edge of the worksheet it will return the cell on the edge of that worksheet.

So Range.End is not a trivial function.

4. .row returns the row index of that cell.

You can use inWaiting() to get the amount of bytes available at the input queue.

Then you can use read() to read the bytes, something like that:

While True:
    bytesToRead = ser.inWaiting()
    ser.read(bytesToRead)

Why not to use readline() at this case from Docs:

Read a line which is terminated with end-of-line (eol) character (\n by default) or until timeout.

You are waiting for the timeout at each reading since it waits for eol. the serial input Q remains the same it just a lot of time to get to the "end" of the buffer, To understand it better: you are writing to the input Q like a race car, and reading like an old car :)

I tried the code:

tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

In the viewDidLoad section and xcode6 showed a warning. I have put a "self." in front of it and now it works fine. so the working code I use is:

self.tableView.tableFooterView = [[UIView alloc] initWithFrame:CGRectZero];

You can use following approach:

import org.apache.commons.codec.binary.Base64;

// Encode data on your side using BASE64
byte[] bytesEncoded = Base64.encodeBase64(str.getBytes());
System.out.println("encoded value is " + new String(bytesEncoded));

// Decode data on other side, by processing encoded data
byte[] valueDecoded = Base64.decodeBase64(bytesEncoded);
System.out.println("Decoded value is " + new String(valueDecoded));

Hope this answers your doubt.

If you're getting your data from a state variable or props, the Text component has a style prop with minWidth, maxWidth.

example

const {height,width} = Dimensions.get('screen');

const string = `This is the description coming from the state variable, It may long thank this` 

<Text style={{ maxWidth:width/2}}>{string}</Text>

This will display text 50% width of your screen

If you want to implement autocomplete functionality, then Completion Suggester is the most neat solution. The next blog post contains a very clear description how this works.

In two words, it's an in-memory data structure called an FST which contains valid suggestions and is optimised for fast retrieval and memory usage. Essentially, it is just a graph. For instance, and FST containing the words hotel, marriot, mercure, munchen and munich would look like this:

While sizeof works for this specific type of string:

char str[] = "content";
int charcount = sizeof str - 1; // -1 to exclude terminating '\0'

It does not work if str is pointer (sizeof returns size of pointer, usually 4 or 8) or array with specified length (sizeof will return the byte count matching specified length, which for char type are same).

Just use strlen().

In languages that support regular expressions with non-capturing groups:

((?:[^/]*/)*)(.*)

I'll explain the gnarly regex by exploding it...

(
  (?:
    [^/]*
    /
  )
  *
)
(.*)

What the parts mean:

(  -- capture group 1 starts
  (?:  -- non-capturing group starts
    [^/]*  -- greedily match as many non-directory separators as possible
    /  -- match a single directory-separator character
  )  -- non-capturing group ends
  *  -- repeat the non-capturing group zero-or-more times
)  -- capture group 1 ends
(.*)  -- capture all remaining characters in group 2

Example

To test the regular expression, I used the following Perl script...

#!/usr/bin/perl -w

use strict;
use warnings;

sub test {
  my $str = shift;
  my $testname = shift;

  $str =~ m#((?:[^/]*/)*)(.*)#;

  print "$str -- $testname\n";
  print "  1: $1\n";
  print "  2: $2\n\n";
}

test('/var/log/xyz/10032008.log', 'absolute path');
test('var/log/xyz/10032008.log', 'relative path');
test('10032008.log', 'filename-only');
test('/10032008.log', 'file directly under root');

The output of the script...

/var/log/xyz/10032008.log -- absolute path
  1: /var/log/xyz/
  2: 10032008.log

var/log/xyz/10032008.log -- relative path
  1: var/log/xyz/
  2: 10032008.log

10032008.log -- filename-only
  1:
  2: 10032008.log

/10032008.log -- file directly under root
  1: /
  2: 10032008.log

You are deleting the row from the gridview but you are then going and calling databind again which is just refreshing the gridview to the same state that the original datasource is in.

Either remove it from the datasource and then databind, or databind and remove it from the gridview without redatabinding.

Assuming you want to change the colour of the currently selected link/tab... you're best bet is to apply a class (say active) to the currently selected link/tab and then style this differently.

Example style could be:

li.active, a.active {
  background-color: #f90;
}

It depends on what function you want to run. If you need something done on server side, like querying a database or setting something in the session or anything that can not be done on client side, you need AJAX, else you can do it on client-side with JavaScript. Don't make the server work when you can do what you need to do on client side.

jQuery provides an easy way to do ajax : http://api.jquery.com/jQuery.ajax/

You can use button classes btn-link and btn-xs with type submit, which will make a small invisible button with an icon inside of it. Example:

<button class="btn btn-link btn-xs" type="submit" name="action" value="delete">
    <i class="fa fa-times text-danger"></i>
</button>

protected void finalize() throws Throwable {}

• every class inherits the finalize() method from java.lang.Object
• the method is called by the garbage collector when it determines no more references to the object exist
• the Object finalize method performs no actions but it may be overridden by any class
• normally it should be overridden to clean-up non-Java resources ie closing a file

• if overridding finalize() it is good programming practice to use a try-catch-finally statement and to always call super.finalize(). This is a safety measure to ensure you do not inadvertently miss closing a resource used by the objects calling class

  protected void finalize() throws Throwable {
       try {
           close();        // close open files
       } finally {
           super.finalize();
       }
   }
  

• any exception thrown by finalize() during garbage collection halts the finalization but is otherwise ignored

• finalize() is never run more than once on any object

quoted from: http://www.janeg.ca/scjp/gc/finalize.html

You could also check this article:

• Object finalization and cleanup

I just checked with www.browserscope.org and with IE9 and Chrome 24 you can have 6 concurrent connections to a single domain, and up to 17 to multiple ones.

If I understand your question correctly, you could use a small method like this to give you the results of your URL test:

WebRequest webRequest = WebRequest.Create(url);  
WebResponse webResponse;
try 
{
  webResponse = webRequest.GetResponse();
}
catch //If exception thrown then couldn't get response from address
{
  return 0;
} 
return 1;

You could wrap the above code in a method and use it to perform validation. I hope this answers the question you were asking.

I've written a Timer class based on CTT's answer. It can be used in the following way:

Timer timer = Timer();
timer.start();
/* perform task */
double duration = timer.stop();
timer.printTime(duration);

Here is its implementation:

#include <stdio.h>
#include <stdlib.h>
#include <sys/time.h>
using namespace std;

class Timer {
private:

    timeval startTime;

public:

    void start(){
        gettimeofday(&startTime, NULL);
    }

    double stop(){
        timeval endTime;
        long seconds, useconds;
        double duration;

        gettimeofday(&endTime, NULL);

        seconds  = endTime.tv_sec  - startTime.tv_sec;
        useconds = endTime.tv_usec - startTime.tv_usec;

        duration = seconds + useconds/1000000.0;

        return duration;
    }

    static void printTime(double duration){
        printf("%5.6f seconds\n", duration);
    }
};

Try command + t. It works for me.

Here is the list of classes and functions:

open System
open System.Collections.Generic
open System.Linq
open System.Threading.Tasks
open Microsoft.AspNetCore.Mvc
open Microsoft.Extensions.Logging
open Microsoft.AspNetCore.Authorization
open Microsoft.AspNetCore.Authentication
open Microsoft.AspNetCore.Authentication.JwtBearer
open Microsoft.IdentityModel.Tokens
open System.IdentityModel.Tokens
open System.IdentityModel.Tokens.Jwt
open Microsoft.IdentityModel.JsonWebTokens
open System.Text
open Newtonsoft.Json
open System.Security.Claims
    let theKey = "VerySecretKeyVerySecretKeyVerySecretKey"
    let securityKey = SymmetricSecurityKey(Encoding.UTF8.GetBytes(theKey))
    let credentials = SigningCredentials(securityKey, SecurityAlgorithms.RsaSsaPssSha256)
    let expires = DateTime.UtcNow.AddMinutes(123.0) |> Nullable
    let token = JwtSecurityToken(
                    "lahoda-pro-issuer", 
                    "lahoda-pro-audience",
                    claims = null,
                    expires =  expires,
                    signingCredentials = credentials
        )

    let tokenString = JwtSecurityTokenHandler().WriteToken(token)

But it would be possible if one were used in place of the variable in @html.Hidden field. As in this example.

@Html.Hidden("myVar", 0);

set the field per script:

<script>
function setMyValue(value) {
     $('#myVar').val(value);       
}
</script>

I hope I can at least offer no small Workaround.

Stack memory allocation (function variables, local variables) can be problematic when your stack is too "deep" and you overflow the memory available to stack allocations. The heap is for objects that need to be accessed from multiple threads or throughout the program lifecycle. You can write an entire program without using the heap.

You can leak memory quite easily without a garbage collector, but you can also dictate when objects and memory is freed. I have run in to issues with Java when it runs the GC and I have a real time process, because the GC is an exclusive thread (nothing else can run). So if performance is critical and you can guarantee there are no leaked objects, not using a GC is very helpful. Otherwise it just makes you hate life when your application consumes memory and you have to track down the source of a leak.

Just use a MaterialButton and the app:backgroundTint and android:textColor attributes:

<MaterialButton
  app:backgroundTint="@color/my_color"
  android:textColor="@android:color/white"/>

I'm passing to Django's template a function, which returns me some records

Why don't you pass to Django template the variable storing function's return value, instead of the function?

I've tried to set fuction's return value to a variable and iterate over variable, but there seems to be no way to set variable in Django template.

You should set variables in Django views instead of templates, and then pass them to the template.

You can have multiple CTEs in one query, as well as reuse a CTE:

WITH    cte1 AS
        (
        SELECT  1 AS id
        ),
        cte2 AS
        (
        SELECT  2 AS id
        )
SELECT  *
FROM    cte1
UNION ALL
SELECT  *
FROM    cte2
UNION ALL
SELECT  *
FROM    cte1

Note, however, that SQL Server may reevaluate the CTE each time it is accessed, so if you are using values like RAND(), NEWID() etc., they may change between the CTE calls.

Using conda install graphviz and conda install python-graphviz to install GraphViz on Windows10 the path needed was C:/ProgramData/Anaconda3/Library/bin/graphviz/ for me. I.e. adding

import os
os.environ["PATH"] += os.pathsep + 'C:/ProgramData/Anaconda3/Library/bin/graphviz/'

solved the issue for me.

I had a similar problem. I was using the "$. GetJSON" jQuery and everything worked perfectly in Firefox and Chrome.

But it did not work in IE. So I tried to directly access the URL of json, but in IE it asked if I wanted to download the file.

After much searching I saw that there must be a header in the result with a content-type, in my case, the content-type was:

header("Content-type: text/html; charset=iso-8859-1");

But when the page that made the request receives this json, in IE, you have to be specified SAME CONTENT-TYPE, in my case was:

$.getJSON (
"<? site_url php echo (" ajax / tipoMenu ")?>"
{contentType: 'text / html; charset = utf-8'},
function (result) {

hugs

JComboBox mycombo=new JComboBox(); //Creates mycombo JComboBox.
add(mycombo); //Adds it to the jframe.

mycombo.addItem("Hello Nepal");  //Adds data to the JComboBox.

String s=String.valueOf(mycombo.getSelectedItem());  //Assigns "Hello Nepal" to s.

System.out.println(s);  //Prints "Hello Nepal".

Under Linux you can use the very powerful recode command to try and convert between the different charsets as well as any line ending issues. recode -l will show you all of the formats and encodings that the tool can convert between. It is likely to be a VERY long list.
