You have two span6 divs within your row so that will take up the whole 12 spans that a row is made up of.

Adding pull-right to the second span6 div isn't going to do anything to it as it's already sitting to the right.

If you mean you want to have the text in the second span6 div aligned to the right then simple add a new class to that div and give it the text-align: right value e.g.

.myclass {
    text-align: right;
}

UPDATE:

EricFreese pointed out that in the 2.3 release of Bootstrap (last week) they've added text-align utility classes that you can use:

• .text-left
• .text-center
• .text-right

FWIW, @SergeyL's answer is great, but here is a slight variant for testing. Note the change in logical or to logical and.

main.c has a main wrapper like this:

#if !defined(TEST_SPI) && !defined(TEST_SERIAL) && !defined(TEST_USB)
int main(int argc, char *argv[]) {
  // the true main() routine.
}

spi.c, serial.c and usb.c have main wrappers for their respective test code like this:

#ifdef TEST_USB
int main(int argc, char *argv[]) {
  // the  main() routine for testing the usb code.
}

config.h Which is included by all the c files has an entry like this:

// Uncomment below to test the serial
//#define TEST_SERIAL


// Uncomment below to test the spi code
//#define TEST_SPI

// Uncomment below to test the usb code
#define TEST_USB

You could create a function that reads an integer between 1 and 23 or returns 0 if non-int

e.g.

int getInt()
{
  int n = 0;
  char buffer[128];
  fgets(buffer,sizeof(buffer),stdin);
  n = atoi(buffer); 
  return ( n > 23 || n < 1 ) ? 0 : n;
}

In command prompt:

SET PATH = "%PATH%;%SystemRoot%\Microsoft.NET\Framework\v2.0.50727"

Processing speed may not be the only relevant matter, however, as that's the question, here are some numbers in a benchmark: JSON vs. XML: Some hard numbers about verbosity. For the speed, in this simple benchmark, XML presents a 21% overhead over JSON.

An important note about the verbosity, which is as the article says, the most common complain: this is not so much relevant in practice (neither XML nor JSON data are typically handled by humans, but by machines), even if for the matter of speed, it requires some reasonable more time to compress.

Also, in this benchmark, a big amount of data was processed, and a typical web application won't transmit data chunks of such sizes, as big as 90MB, and compression may not be beneficial (for small enough data chunks, a compressed chunk will be bigger than the uncompressed chunk), so not applicable.

Still, if no compression is involved, JSON, as obviously terser, will weight less over the transmission channel, especially if transmitted through a WebSocket connection, where the absence of the classic HTTP overhead may make the difference at the advantage of JSON, even more significant.

After transmission, data is to be consumed, and this count in the overall processing time. If big or complex enough data are to be transmitted, the lack of a schema automatically checked for by a validating XML parser, may require more check on JSON data; these checks would have to be executed in JavaScript, which is not known to be particularly fast, and so it may present an additional overhead over XML in such cases.

Anyway, only testing will provides the answer for your particular use-case (if speed is really the only matter, and not standard nor safety nor integrity…).

Update 1: worth to mention, is EXI, the binary XML format, which offers compression at less cost than using Gzip, and save processing otherwise needed to decompress compressed XML. EXI is to XML, what BSON is to JSON. Have a quick overview here, with some reference to efficiency in both space and time: EXI: The last binary standard?.

Update 2: there also exists a binary XML performance reports, conducted by the W3C, as efficiency and low memory and CPU footprint, is also a matter for the XML area too: Efficient XML Interchange Evaluation.

Update 2015-03-01

Worth to be noticed in this context, as HTTP overhead was raised as an issue: the IANA has registered the EXI encoding (the efficient binary XML mentioned above), as a a Content Coding for the HTTP protocol (alongside with compress, deflate and gzip). This means EXI is an option which can be expected to be understood by browsers among possibly other HTTP clients. See Hypertext Transfer Protocol Parameters (iana.org).

As Bhavik Shah says, you can do it in JAVA_OPTS, but the recommended way (as per catalina.sh) is to use CATALINA_OPTS:

#   CATALINA_OPTS   (Optional) Java runtime options used when the "start",
#                   "run" or "debug" command is executed.
#                   Include here and not in JAVA_OPTS all options, that should
#                   only be used by Tomcat itself, not by the stop process,
#                   the version command etc.
#                   Examples are heap size, GC logging, JMX ports etc.

#   JAVA_OPTS       (Optional) Java runtime options used when any command
#                   is executed.
#                   Include here and not in CATALINA_OPTS all options, that
#                   should be used by Tomcat and also by the stop process,
#                   the version command etc.
#                   Most options should go into CATALINA_OPTS.

You could be using the 32 bit version, so you should prob try at the command line from the Framework (not Framework64) folder.

IE Did you try it from C:\Windows\Microsoft.NET\Framework\v4.0.30319 rather than the 64 version? If you ref 32 bit libs you can be forced to 32 bit version (some other reasons as well if I recall)

Is your site a child of another site in IIS?

For more details on this (since it applies to various types of apps running on .NET) see Scott's post at:

32-bit and 64-bit confusion around x86 and x64 and the .NET Framework and CLR

Try with

c:\WINDOWS\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -iru

When multiple versions of the .NET Framework are executing side-by-side on a single computer, the ASP.NET ISAPI version mapped to an ASP.NET application determines which version of the common language runtime (CLR) is used for the application.

Above command will Installs the version of ASP.NET that is associated with Aspnet_regiis.exe and only registers ASP.NET in IIS.

When you don't know whether there are any results, use getResultList().

List<User> foundUsers = (List<User>) query.getResultList();
        if (foundUsers == null || foundUsers.isEmpty()) {
            return false;
        }
User foundUser = foundUsers.get(0);

This is fixed by adding a new option Retain CR\LF on copy or save under the Tools -> Options... menu, Query Results -> SQL Server -> Results to Grid.

You need to open new session (window) to make the change take a place.

The default is unselected (false) which means that copying/saving from the grid will copy the text as it is displayed (with CR\LF replaced with spaces). If set to true the text will be copied/saved from the grid as it actually is stored - without the character replacement.

In case people missed following the chain of connect items (leading to https://connect.microsoft.com/SQLServer/feedback/details/735714), this issue has been fixed in the preview version of SSMS.

You can download this for free from https://msdn.microsoft.com/library/mt238290.aspx, it is a standalone download so does not need the full SQL media anymore.

(Note - the page at https://msdn.microsoft.com/library/ms190078.aspx currently isn't updated with this information. I'm following up on this so it should reflect the new option soon)

I have written my own that you can use. This one works has sqlite, is thread safe and is in C++ for UNIX.

You should be able to pick it apart and use the C compatible code.

You might be better off using the Properties Service as you can use these as a kind of persistent global variable.

click 'file > project properties > project properties' to set a key value, or you can use

PropertiesService.getScriptProperties().setProperty('mykey', 'myvalue');

The data can be retrieved with

var myvalue = PropertiesService.getScriptProperties().getProperty('mykey');

From that error, I would say that your code is fine, at least the part that calls the webservice. The error seems to be in the actual web service.

To get the error from the web server, add a try catch and catch a WebException. A WebException has a property called Response which is a HttpResponse. you can then log anything that is returned, and upload you code. Check back later in the logs and see what is actually being returned.

Use something like this:

page1.php

<?php
session_start();
$_SESSION['myValue']=3; // You can set the value however you like.
?>

Any other PHP page:

<?php
session_start();
echo $_SESSION['myValue'];
?>

A few notes to keep in mind though: You need to call session_start() BEFORE any output, HTML, echos - even whitespace.

You can keep changing the value in the session - but it will only be able to be used after the first page - meaning if you set it in page 1, you will not be able to use it until you get to another page or refresh the page.

The setting of the variable itself can be done in one of a number of ways:

$_SESSION['myValue']=1;
$_SESSION['myValue']=$var;
$_SESSION['myValue']=$_GET['YourFormElement'];

And if you want to check if the variable is set before getting a potential error, use something like this:

if(!empty($_SESSION['myValue'])
{
    echo $_SESSION['myValue'];
}
else
{
    echo "Session not set yet.";
}

Could you try something like this for example I think what you are wanting to utilize is the port.ReadExisting() Method

 using System;
 using System.IO.Ports;

 class SerialPortProgram 
 { 
  // Create the serial port with basic settings 
    private SerialPort port = new   SerialPort("COM1",
      9600, Parity.None, 8, StopBits.One); 
    [STAThread] 
    static void Main(string[] args) 
    { 
      // Instatiate this 
      SerialPortProgram(); 
    } 

    private static void SerialPortProgram() 
    { 
        Console.WriteLine("Incoming Data:");
         // Attach a method to be called when there
         // is data waiting in the port's buffer 
        port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived); 
        // Begin communications 
        port.Open(); 
        // Enter an application loop to keep this thread alive 
        Console.ReadLine();
     } 

    private void port_DataReceived(object sender, SerialDataReceivedEventArgs e) 
    { 
       // Show all the incoming data in the port's buffer
       Console.WriteLine(port.ReadExisting()); 
    } 
}

Or is you want to do it based on what you were trying to do , you can try this

public class MySerialReader : IDisposable
{
  private SerialPort serialPort;
  private Queue<byte> recievedData = new Queue<byte>();

  public MySerialReader()
  {
    serialPort = new SerialPort();
    serialPort.Open();
    serialPort.DataReceived += serialPort_DataReceived;
  }

  void serialPort_DataReceived(object s, SerialDataReceivedEventArgs e)
  {
    byte[] data = new byte[serialPort.BytesToRead];
    serialPort.Read(data, 0, data.Length);
    data.ToList().ForEach(b => recievedData.Enqueue(b));
    processData();
  }

  void processData()
  {
    // Determine if we have a "packet" in the queue
    if (recievedData.Count > 50)
    {
        var packet = Enumerable.Range(0, 50).Select(i => recievedData.Dequeue());
    }
  }

  public void Dispose()
  {
        if (serialPort != null)
        {
            serialPort.Dispose();
        }
  }

If you are logging in to your gmail account from a new application or device, Google might be blocking that device. Try following these steps:

To protect your account, Google might make it harder to sign in to your account if we suspect it isn’t you. For example, Google might ask for additional information besides your username and password if you are traveling or if you try to sign in to your account from a new device.

Go to https://g.co/allowaccess from a different device you have previously used to access your Google account and follow the instructions. Try signing in again from the blocked app.

The icons you are seeing on desktop is not a icon file. They are either executable files .exe or shortcuts of any application .lnk. So can only set icon which have .ico extension.

Go to Project Menu -> Your_Project_Name Properties -> Application TAB -> Resources -> Icon

browse for your Icon, remember it must have .ico extension

You can make your icon in Visual Studio

Go to Project Menu -> Add New Item -> Icon File

you can follow these simple steps:

FIRST WAY :

first copy the SQL dump file from your local directory to the mysql container. use docker cp command

docker cp [SRC-Local path to sql file] [container-name or container-id]:[DEST-path to copy to]

docker cp ./data.sql mysql-container:/home

and then execute the mysql-container using (NOTE: in case you are using alpine version you need to replace bash with sh in the given below command.)

docker exec -it -u root mysql-container bash

and then you can simply import this SQL dump file.

mysql [DB_NAME] < [SQL dump file path]

mysql movie_db < /home/data.sql

SECOND WAY : SIMPLE

docker cp ./data.sql mysql-container:/docker-entrypoint-initdb.d/

As mentioned in the mysql Docker hub official page.

Whenever a container starts for the first time, a new database is created with the specified name in MYSQL_DATABASE variable - which you can pass by setting up the environment variable see here how to set environment variables

By default container will execute files with extensions .sh, .sql and .sql.gz that are found in /docker-entrypoint-initdb.d folder. Files will be executed in alphabetical order. this way your SQL files will be imported by default to the database specified by the MYSQL_DATABASE variable.

for more details you can always visit the official page

convert_objects is deprecated.

For pandas >= 0.17.0, use pd.to_numeric

Remove static keyword in method definition. Keep it just in your class definition.

static keyword placed in .cpp file means that a certain function has a static linkage, ie. it is accessible only from other functions in the same file.

String jsonErrorString=((HttpClientErrorException)exception).getResponseBodyAsString();
JSONObject jsonObj=null;
String errorDetails=null;
String status=null;
try {
        jsonObj = new JSONObject(jsonErrorString);
        int index =jsonObj.getString("detail").indexOf(":");
                errorDetails=jsonObj.getString("detail").substring(index);
                status=jsonObj.getString("status");

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            item.put("status", status);
            item.put("errordetailMsg", errorDetails);

I was having the same problem when my workspace was in E:\ drive. Then I changed my workspace location to C:\User\\ location. The problem seems to be solved now.

If you can use psutil, then this works perfectly:

import subprocess

import psutil


def kill(proc_pid):
    process = psutil.Process(proc_pid)
    for proc in process.children(recursive=True):
        proc.kill()
    process.kill()


proc = subprocess.Popen(["infinite_app", "param"], shell=True)
try:
    proc.wait(timeout=3)
except subprocess.TimeoutExpired:
    kill(proc.pid)

With Vagrant now you can have Docker as a provider. http://docs.vagrantup.com/v2/docker/. Docker provider can be used instead of VirtualBox or VMware.

Please note that you can also use Docker for provisioning with Vagrant. This is very different than using Docker as a provider. http://docs.vagrantup.com/v2/provisioning/docker.html

This means you can replace Chef or Puppet with Docker. You can use combinations like Docker as provider (VM) with Chef as provisioner. Or you can use VirtualBox as provider and Docker as provisioner.

I'm not entirely sure of the general purpose of the function, but you could always do this:

function getMachine(color, qty) {
    var retval;
    $("#getMachine li").each(function() {
        var thisArray = $(this).text().split("~");
        if(thisArray[0] == color&& qty>= parseInt(thisArray[1]) && qty<= parseInt(thisArray[2])) {
            retval = thisArray[3];
            return false;
        }
    });
    return retval;
}

var retval = getMachine(color, qty);

You look like you're trying to write C in Python. If you want to find something in a sequence, Python has builtin functions to do that, like

value = sequence.index(blarg)

filter expects to get a function and something that it can iterate over. The function should return True or False for each element in the iterable. In your particular example, what you're looking to do is something like the following:

In [47]: def greetings(x):
   ....:     return x == "hello"
   ....:

In [48]: filter(greetings, ["hello", "goodbye"])
Out[48]: ['hello']

Note that in Python 3, it may be necessary to use list(filter(greetings, ["hello", "goodbye"])) to get this same result.

The other features of CodeLens like: Show Bugs, Show Test Status, etc (other than Show Reference) might be useful.

However, if the only way to disable Show References is to disable CodeLens altogether.

Then, I guess I could do just that.

Furthermore, I would do like I always have, 'right-click on a member and choose Find all References or Ctrl+K, R'

If I wanted to know what references the member -- I too like not having any extra information crammed into my code, like extra white-space.

In short, uncheck Codelens...

To search across all the branches

git log --all --grep='Build 0051'

Once you know which commit you want to get to

git checkout <the commit hash>

Well, you are using both frame.setSize() and frame.pack().

You should use one of them at one time.

Using setSize() you can give the size of frame you want but if you use pack(), it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.

Try removing frame.pack() from your code or putting it before setting size and then run it.

Reproducing tim_yates answer on current hardware and adding leftShift() and concat() method to check the finding:

  'String leftShift' {
    foo << bar << baz
  }
  'String concat' {
    foo.concat(bar)
       .concat(baz)
       .toString()
  }

The outcome shows concat() to be the faster solution for a pure String, but if you can handle GString somewhere else, GString template is still ahead, while honorable mention should go to leftShift() (bitwise operator) and StringBuffer() with initial allocation:

In my experience, tests of the form if (ptr) or if (!ptr) are preferred. They do not depend on the definition of the symbol NULL. They do not expose the opportunity for the accidental assignment. And they are clear and succinct.

Edit: As SoapBox points out in a comment, they are compatible with C++ classes such as auto_ptr that are objects that act as pointers and which provide a conversion to bool to enable exactly this idiom. For these objects, an explicit comparison to NULL would have to invoke a conversion to pointer which may have other semantic side effects or be more expensive than the simple existence check that the bool conversion implies.

I have a preference for code that says what it means without unneeded text. if (ptr != NULL) has the same meaning as if (ptr) but at the cost of redundant specificity. The next logical thing is to write if ((ptr != NULL) == TRUE) and that way lies madness. The C language is clear that a boolean tested by if, while or the like has a specific meaning of non-zero value is true and zero is false. Redundancy does not make it clearer.

You should use Measure-Object to count things. In this case it would look like:

Write-Host ( Get-ChildItem c:\MyFolder | Measure-Object ).Count;

or if that's too long

Write-Host ( dir c:\MyFolder | mo).Count;

and in PowerShell 4.0 use the measure alias instead of mo

Write-Host (dir c:\MyFolder | measure).Count;

The simplest solution simply is:

<a href="#" onclick="event.preventDefault(); myfunc({a:1, b:'hi'});" />click</a>

It's actually a good way of doing cache busting for documents with a fallback for no JS enabled browsers (no cache busting if no JS)

<a onclick="
if(event.preventDefault) event.preventDefault(); else event.returnValue = false;
window.location = 'http://www.domain.com/docs/thingy.pdf?cachebuster=' + 
Math.round(new Date().getTime() / 1000);" 
href="http://www.domain.com/docs/thingy.pdf">

If JavaScript is enabled, it opens the PDF with a cache busting query string, if not it just opens the PDF.

Your Application.java class should extend the SpringBootServletInitializer class ex:

public class Application extends SpringBootServletInitializer {}

You cannot invoke JavaScript functions in standard HTML attributes other than onXXX. Just assign it during window onload.

<script type="text/javascript">
    window.onload = function() {
        document.myform.action = get_action();
    }

    function get_action() {
        return form_action;
    }
</script>

<form name="myform">
    ...
</form>

You see that I've given the form a name, so that it's easily accessible in document.

Alternatively, you can also do it during submit event:

<script type="text/javascript">
    function get_action(form) {
        form.action = form_action;
    }
</script>

<form onsubmit="get_action(this);">
    ...
</form>

If you don't want to use CSS try this one between your rows:

    <tr>
    <td class="divider"><hr /></td>
    </tr>

Cheers!!

You should follow the instructions provided in the documentation, using the web.config.

<aspNetCore processPath="dotnet"
        arguments=".\MyApp.dll"
        stdoutLogEnabled="false"
        stdoutLogFile="\\?\%home%\LogFiles\aspnetcore-stdout">
  <environmentVariables>
    <environmentVariable name="ASPNETCORE_ENVIRONMENT" value="Production" />
    <environmentVariable name="CONFIG_DIR" value="f:\application_config" />
  </environmentVariables>
</aspNetCore>

Note that you can also set other environment variables as well.

The ASP.NET Core Module allows you specify environment variables for the process specified in the processPath attribute by specifying them in one or more environmentVariable child elements of an environmentVariables collection element under the aspNetCore element. Environment variables set in this section take precedence over system environment variables for the process.

For center or positioning the background image you should use background-position property . The background-position property sets the starting position of a background image from top and left sides of the element . The CSS Syntax is background-position : xvalue yvalue; .

"xvalue" and "yvalue" supported values are length units like px and percentage and direction names like left, right and etc .

The "xvalue" is the horizontal position of the background and starts from top of the element . It means if you use 50px it will be "50px" away from top of the elements . And "yvalue" is the vertical position that has the same condition .

So if you use background-position: center; your background image will be centered .

But I always use this code :

.yourclass {_x000D_
  background: url(image.png) no-repeat center /cover;_x000D_
 }

I know it is so confusing but it means :

.yourclass {_x000D_
  background-image: url(image.png);_x000D_
  background-position: center;_x000D_
  background-size: cover;_x000D_
  background-repeat: no-repeat;_x000D_
}

And I know that too the background-size is a new property and in the compressed code what is /cover but these codes means fill background sizing and positioning in windows desktop background .

You can see more details about background-position in here and background-size in here .

NOTE: nosid's answer shows how to add to an existing collection using forEachOrdered(). This is a useful and effective technique for mutating existing collections. My answer addresses why you shouldn't use a Collector to mutate an existing collection.

The short answer is no, at least, not in general, you shouldn't use a Collector to modify an existing collection.

The reason is that collectors are designed to support parallelism, even over collections that aren't thread-safe. The way they do this is to have each thread operate independently on its own collection of intermediate results. The way each thread gets its own collection is to call the Collector.supplier() which is required to return a new collection each time.

These collections of intermediate results are then merged, again in a thread-confined fashion, until there is a single result collection. This is the final result of the collect() operation.

A couple answers from Balder and assylias have suggested using Collectors.toCollection() and then passing a supplier that returns an existing list instead of a new list. This violates the requirement on the supplier, which is that it return a new, empty collection each time.

This will work for simple cases, as the examples in their answers demonstrate. However, it will fail, particularly if the stream is run in parallel. (A future version of the library might change in some unforeseen way that will cause it to fail, even in the sequential case.)

Let's take a simple example:

List<String> destList = new ArrayList<>(Arrays.asList("foo"));
List<String> newList = Arrays.asList("0", "1", "2", "3", "4", "5");
newList.parallelStream()
       .collect(Collectors.toCollection(() -> destList));
System.out.println(destList);

When I run this program, I often get an ArrayIndexOutOfBoundsException. This is because multiple threads are operating on ArrayList, a thread-unsafe data structure. OK, let's make it synchronized:

List<String> destList =
    Collections.synchronizedList(new ArrayList<>(Arrays.asList("foo")));

This will no longer fail with an exception. But instead of the expected result:

[foo, 0, 1, 2, 3]

it gives weird results like this:

[foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0, foo, 2, 3, foo, 2, 3, 1, 0]

This is the result of the thread-confined accumulation/merging operations I described above. With a parallel stream, each thread calls the supplier to get its own collection for intermediate accumulation. If you pass a supplier that returns the same collection, each thread appends its results to that collection. Since there is no ordering among the threads, results will be appended in some arbitrary order.

Then, when these intermediate collections are merged, this basically merges the list with itself. Lists are merged using List.addAll(), which says that the results are undefined if the source collection is modified during the operation. In this case, ArrayList.addAll() does an array-copy operation, so it ends up duplicating itself, which is sort-of what one would expect, I guess. (Note that other List implementations might have completely different behavior.) Anyway, this explains the weird results and duplicated elements in the destination.

You might say, "I'll just make sure to run my stream sequentially" and go ahead and write code like this

stream.collect(Collectors.toCollection(() -> existingList))

anyway. I'd recommend against doing this. If you control the stream, sure, you can guarantee that it won't run in parallel. I expect that a style of programming will emerge where streams get handed around instead of collections. If somebody hands you a stream and you use this code, it'll fail if the stream happens to be parallel. Worse, somebody might hand you a sequential stream and this code will work fine for a while, pass all tests, etc. Then, some arbitrary amount of time later, code elsewhere in the system might change to use parallel streams which will cause your code to break.

OK, then just make sure to remember to call sequential() on any stream before you use this code:

stream.sequential().collect(Collectors.toCollection(() -> existingList))

Of course, you'll remember to do this every time, right? :-) Let's say you do. Then, the performance team will be wondering why all their carefully crafted parallel implementations aren't providing any speedup. And once again they'll trace it down to your code which is forcing the entire stream to run sequentially.

Don't do it.

(SELECT <some columns>
FROM mytable
<maybe some joins here>
WHERE <various conditions>
ORDER BY date DESC
LIMIT 10)

UNION ALL

(SELECT <some columns>
FROM mytable
<maybe some joins here>
WHERE <various conditions>
ORDER BY date ASC    
LIMIT 10)

Simplest thing usually is to create matching Object hierarchy, like so:

public class Wrapper {
   public Data data;
}
static class Data {
   public Translation[] translations;
}
static class Translation {
   public String translatedText;
}

and then bind using GSON, traverse object hierarchy via fields. Adding getters and setters is pointless for basic data containers.

So something like:

Wrapper value = GSON.fromJSON(jsonString, Wrapper.class);
String text = value.data.translations[0].translatedText;

There is a great solution for this problem ,You can use the Merge Keyword of Sql

Merge MyTargetTable hba
USING (SELECT Id = 8, Name = 'Product Listing Message') temp 
ON temp.Id = hba.Id
WHEN NOT matched THEN 
INSERT (Id, Name) VALUES (temp.Id, temp.Name);

You can check this before following, below is the sample

IF OBJECT_ID ('dbo.TargetTable') IS NOT NULL
    DROP TABLE dbo.TargetTable
GO

CREATE TABLE dbo.TargetTable
    (
    Id   INT NOT NULL,
    Name VARCHAR (255) NOT NULL,
    CONSTRAINT PK_TargetTable PRIMARY KEY (Id)
    )
GO



INSERT INTO dbo.TargetTable (Name)
VALUES ('Unknown')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Mapping')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Update')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Message')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Switch')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('Unmatched')
GO

INSERT INTO dbo.TargetTable (Name)
VALUES ('ProductMessage')
GO


Merge MyTargetTable hba
USING (SELECT Id = 8, Name = 'Listing Message') temp 
ON temp.Id = hba.Id
WHEN NOT matched THEN 
INSERT (Id, Name) VALUES (temp.Id, temp.Name);

Adding <validation validateIntegratedModeConfiguration="false"/> addresses the symptom, but is not appropriate for all circumstances. Having ran around this issue a few times, I hope to help others not only overcome the problem but understand it. (Which becomes more and more important as IIS 6 fades into myth and rumor.)

Background:

This issue and the confusion surrounding it started with the introduction of ASP.NET 2.0 and IIS 7. IIS 6 had and continues to have only one pipeline mode, and it is equivalent to what IIS 7+ calls "Classic" mode. The second, newer, and recommended pipeline mode for all applications running on IIS 7+ is called "Integrated" mode.

So, what's the difference? The key difference is how ASP.NET interacts with IIS.

• Classic mode is limited to an ASP.NET pipeline that cannot interact with the IIS pipeline. Essentially a request comes in and if IIS 6/Classic has been told, through server configuration, that ASP.NET can handle it then IIS hands off the request to ASP.NET and moves on. The significance of this can be gleaned from an example. If I were to authorize access to static image files, I would not be able to do it with an ASP.NET module because the IIS 6 pipeline will handle those requests itself and ASP.NET will never see those requests because they were never handed off.* On the other hand, authorizing which users can access a .ASPX page such as a request for Foo.aspx is trivial even in IIS 6/Classic because IIS always hands those requests off to the ASP.NET pipeline. In Classic mode ASP.NET does not know what it hasn't been told and there is a lot that IIS 6/Classic may not be telling it.

• Integrated mode is recommended because ASP.NET handlers and modules can interact directly with the IIS pipeline. No longer does the IIS pipeline simply hand off the request to the ASP.NET pipeline, now it allows ASP.NET code to hook directly into the IIS pipeline and all the requests that hit it. This means that an ASP.NET module can not only observe requests to static image files, but can intercept those requests and take action by denying access, logging the request, etc.

Overcoming the error:

1. If you are running an older application that was originally built for IIS 6, perhaps you moved it to a new server, there may be absolutely nothing wrong with running the application pool of that application in Classic mode. Go ahead you don't have to feel bad.

2. Then again maybe you are giving your application a face-lift or it was chugging along just fine until you installed a 3rd party library via NuGet, manually, or by some other means. In that case it is entirely possible httpHandlers or httpModules have been added to system.web. The outcome is the error that you are seeing because validateIntegratedModeConfiguration defaults true. Now you have two choices:

   1. Remove the httpHandlers and httpModules elements from system.web. There are a couple possible outcomes from this:
      • Everything works fine, a common outcome;
      • Your application continues to complain, there may be a web.config in a parent folder you are inheriting from, consider cleaning up that web.config too;
      • You grow tired of removing the httpHandlers and httpModules that NuGet packages keep adding to system.web, hey do what you need to.
3. If those options do not work or are more trouble than it is worth then I'm not going to tell you that you can't set validateIntegratedModeConfiguration to false, but at least you know what you're doing and why it matters.

Good reads:

• ASP.NET 2.0 Breaking Changes on IIS 7.0
• ASP.NET Integration with IIS 7
• HTTP Handlers and HTTP Modules Overview

*Of course there are ways to get all kind of strange things into the ASP.NET pipeline from IIS 6/Classic via incantations like wildcard mappings, if you like that sort of thing.

I would recommend using CSS for this. You should create a CSS rule to enforce the centering, for example:

.ui-helper-center {
    text-align: center;
}

And then add the ui-helper-center class to the table cells for which you wish to control the alignment:

<td class="ui-helper-center">Content</td>

EDIT: Since this answer was accepted, I felt obligated to edit out the parts that caused a flame-war in the comments, and to not promote poor and outdated practices.

See Gabe's answer for how to include the CSS rule into your page.

Multiply by 1000 then use Truncate then divide by 1000.

What worked for me was to first add my SSH key of the new computer, I followed these instructions from GitLab - add SSH key. Note that since I'm on Win10, I had to do all these commands in Git Bash on Windows (it didn't work in regular DOS cmd Shell).

Then again in Git Bash, I had to do a git clone of the repo that I had problems with, and in my case I had to clone it to a different name since I already had it locally and didn't want to lose my commits. For example

git clone ssh://git@gitServerUrl/myRepo.git myRepo2

Then I got the prompt to add it to known hosts list, the question might be this one:

Are you sure you want to continue connecting (yes/no)?

I typed "yes" and it finally worked, you should typically get a message similar to this:

Warning: Permanently added '[your repo link]' (ECDSA) to the list of known hosts.

Note: if you are on Windows, make sure that you use Git Bash for all the commands, this did not work in regular cmd shell or powershell, I really had to do this in Git Bash.

Lastly I deleted the second clone repo (myRepo2 in the example) and went back to my first repo and I could finally do all the Git stuff like normal in my favorite editor VSCode.

<script type="text/javascript">
    var IdAry=['reports1'];
    window.onload=function() {
     for (var zxc0=0;zxc0<IdAry.length;zxc0++){
      var el=document.getElementById(IdAry[zxc0]);
      if (el){
       el.onmouseover=function() {
         changeText(this,'hide','show')
        }
       el.onmouseout=function() {
         changeText(this,'show','hide');
        }
      }
     }
    }
    function changeText(obj,cl1,cl2) {
       obj.getElementsByTagName('SPAN')[0].className=cl1;
       obj.getElementsByTagName('SPAN')[1].className=cl2;
    }
</script>

ur html should look like this

<p id="reports1">
                <span id="span1">Test Content</span>
                <span class="hide">

                    <br /> <br /> This is the content that appears when u hover on the it
                </span>
            </p>

To select all anchors with the data attribute data-customerID==22, you should include the a to limit the scope of the search to only that element type. Doing data attribute searches in a large loop or at high frequency when there are many elements on the page can cause performance issues.

$('a[data-customerID="22"]');

Start by turning the text into a list of lists. That will take care of the parsing part:

lol = list(csv.reader(open('text.txt', 'rb'), delimiter='\t'))

The rest can be done with indexed lookups:

d = dict()
key = lol[6][0]      # cell A7
value = lol[6][3]    # cell D7
d[key] = value       # add the entry to the dictionary
 ...

I would go with unset because it might give the garbage collector a better hint so that the memory can be available again sooner. Be careful that any things the object points to either have other references or get unset first or you really will have to wait on the garbage collector since there would then be no handles to them.

The selected answer dates from a while back. It is not practical to declare every binding in a custom HK2 binder. I'm using Tomcat and I just had to add one dependency. Even though it was designed for Glassfish it fits perfectly into other containers.

   <dependency>
        <groupId>org.glassfish.jersey.containers.glassfish</groupId>
        <artifactId>jersey-gf-cdi</artifactId>
        <version>${jersey.version}</version>
    </dependency>

Make sure your container is properly configured too (see the documentation).

In package.json file. change file like this

"scripts":{ 
   "start": "node ./bin/www", 
   "start-dev": "nodemon ./app.js"
 },

and then execute npm run start-dev

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

You can use toLocaleDateString('fr-CA') on Date object

console.log(new Date('Sun May 11,2014').toLocaleDateString('fr-CA'));

Also I found out that those locales give right result from this locales list List of All Locales and Their Short Codes?

If you find yourself overriding (non-abstract) methods very often, you probably want to take a look at your design. It is very useful when the compiler would not otherwise catch the error. For instance trying to override initValue() in ThreadLocal, which I have done.

Using @Override when implementing interface methods (1.6+ feature) seems a bit overkill for me. If you have loads of methods some of which override and some don't, that probably bad design again (and your editor will probably show which is which if you don't know).

int i = 65;
char c = Convert.ToChar(i);

If you're running Linux I would suggest two tools:

align_image_stack from package hugin-tools - is a commandline program that can automatically correct rotation, scaling, and other distortions (it's mostly intended for compositing HDR photography, but works for video frames and other documents too). More information: http://hugin.sourceforge.net/docs/manual/Align_image_stack.html

compare from package imagemagick - a program that can find and count the amount of different pixels in two images. Here's a neat tutorial: http://www.imagemagick.org/Usage/compare/ uising the -fuzz N% you can increase the error tolerance. The higher the N the higher the error tolerance to still count two pixels as the same.

align_image_stack should correct any offset so the compare command will actually have a chance of detecting same pixels.

In case you want to work with the original MNIST files, here is how you can deserialize them.

If you haven't downloaded the files yet, do that first by running the following in the terminal:

wget http://yann.lecun.com/exdb/mnist/train-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/train-labels-idx1-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-images-idx3-ubyte.gz
wget http://yann.lecun.com/exdb/mnist/t10k-labels-idx1-ubyte.gz

Then save the following as deserialize.py and run it.

import numpy as np
import gzip

IMG_DIM = 28

def decode_image_file(fname):
    result = []
    n_bytes_per_img = IMG_DIM*IMG_DIM

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[16:]

        if len(data) % n_bytes_per_img != 0:
            raise Exception('Something wrong with the file')

        result = np.frombuffer(data, dtype=np.uint8).reshape(
            len(bytes_)//n_bytes_per_img, n_bytes_per_img)

    return result

def decode_label_file(fname):
    result = []

    with gzip.open(fname, 'rb') as f:
        bytes_ = f.read()
        data = bytes_[8:]

        result = np.frombuffer(data, dtype=np.uint8)

    return result

train_images = decode_image_file('train-images-idx3-ubyte.gz')
train_labels = decode_label_file('train-labels-idx1-ubyte.gz')

test_images = decode_image_file('t10k-images-idx3-ubyte.gz')
test_labels = decode_label_file('t10k-labels-idx1-ubyte.gz')

The script doesn't normalize the pixel values like in the pickled file. To do that, all you have to do is

train_images = train_images/255
test_images = test_images/255

Call your hosting company and either have them set up regular log backups or set the recovery model to simple. I'm sure you know what informs the choice, but I'll be explicit anyway. Set the recovery model to full if you need the ability to restore to an arbitrary point in time. Either way the database is misconfigured as is.

For posterity: as of 0.15.0, there is a handy .dt accessor you can use to pull such values from a datetime/period series (in the above case, just sales.timestamp.dt.hour!

By POST file uploads are done (commonly, there are also other methods). Look into the method attribute of the form which contains the file-upload field ;)

The lowest limit of any related setting supersedes a higher setting:

• post_max_size
• upload_max_filesize
• memory_limit

See Handling file uploads: Common Pitfals which explains this in detail and how to calculate the values.

First of all, this line

<img src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />.click()

You're mixing HTML and JavaScript. It doesn't work like that. Get rid of the .click() there.

If you read the JavaScript you've got there, document.getElementById('foo') it's looking for an HTML element with an ID of foo. You don't have one. Give your image that ID:

<img id="foo" src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" />

Alternatively, you could throw the JS in a function and put an onclick in your HTML:

<img src="http://soulsnatcher.bplaced.net/LDRYh.jpg" alt="unfinished bingo card" onclick="myfunction()" />

I suggest you do some reading up on JavaScript and HTML though.

The others are right about needing to move the <img> above the JS click binding too.

Why cant you use the finally block?

Like

try {

} catch (Exception e) {

  // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

} finally { 

 // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

}

EDIT after question amended:

You can do:

int? returnFromFunction2 = null;
    try {
        returnFromFunction2 = function2();
        return returnFromFunction2.value;
        } catch (Exception e) {

          // THIS WILL EXECUTE IF THERE IS AN EXCEPTION IS THROWN IN THE TRY BLOCK

        } finally { 

        if (returnFromFunction2.HasValue) { // do something with value }

         // THIS WILL EXECUTE IRRESPECTIVE OF WHETHER AN EXCEPTION IS THROWN WITHIN THE TRY CATCH OR NOT

        }

$s = "my name is ";

$s .= "keyur";

echo $s; 

result:

my name is keyur

This snippet also solve this question with datePart function. I've also used the right() trick to perform a rpad(x,2,"0").

option explicit

Wscript.Echo "Today is " & myDate(now)

' date formatted as your request
Function myDate(dt)
    dim d,m,y, sep
    sep = "-"
    ' right(..) here works as rpad(x,2,"0")
    d = right("0" & datePart("d",dt),2)
    m = right("0" & datePart("m",dt),2)
    y = datePart("yyyy",dt)
    myDate= m & sep & d & sep & y
End Function

Just becuase your class object has no variables does not mean that it is nothing. Declaring and object and creating an object are two different things. Look and see if you are setting/creating the object.

Take for instance the dictionary object - just because it contains no variables does not mean it has not been created.

Sub test()

Dim dict As Object
Set dict = CreateObject("scripting.dictionary")

If Not dict Is Nothing Then
    MsgBox "Dict is something!"  '<--- This shows
Else
    MsgBox "Dict is nothing!"
End If

End Sub

However if you declare an object but never create it, it's nothing.

Sub test()

Dim temp As Object

If Not temp Is Nothing Then
    MsgBox "Temp is something!"
Else
    MsgBox "Temp is nothing!" '<---- This shows
End If

End Sub

Linus is spot on in the approach, but a few properties are off. It looks like 'AgencyContractId' is your Primary Key, which is unrelated to the output you want to give the user. I think this is what you want (assuming you change your ViewModel to match the data you say you want in your view).

var agencyContracts = _agencyContractsRepository.AgencyContracts
    .GroupBy(ac => new
                   {
                       ac.AgencyID,
                       ac.VendorID,
                       ac.RegionID
                   })
    .Select(ac => new AgencyContractViewModel
                   {
                       AgencyId = ac.Key.AgencyID,
                       VendorId = ac.Key.VendorID,
                       RegionId = ac.Key.RegionID,
                       Total = ac.Sum(acs => acs.Amount) + ac.Sum(acs => acs.Fee)
                   });

This works perfectly

$("#myTable tbody").children( 'tr:not(:first)' ).html("");

Possible in IE and chrome although it does not work in firefox:

<script>
   function toggleZoomScreen() {
       document.body.style.zoom = "80%";
   } 
</script>

<img src="example.jpg" alt="example" onclick="toggleZoomScreen()">

How to specify the JDK version?

Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source & target or (3) with release.

Spring Boot

1. <java.version> is not referenced in the Maven documentation.
   It is a Spring Boot specificity.
   It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :

   1.8

Feel free to use it if you use Spring Boot.

maven-compiler-plugin with source & target

2. Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties are equivalent.

That is indeed :

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

is equivalent to :

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

source

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

maven-compiler-plugin with release instead of source & target

3. The maven-compiler-plugin 3.6 and later versions provide a new way :

   org.apache.maven.plugins maven-compiler-plugin 3.8.0 9

You could also declare just :

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time it will not work as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release : a new JVM standard option that we could pass from Java 9 :

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

The first way (<java.version>) is allowed only if you use Spring Boot.

For Java 8 and below :

About the two other ways : valuing the maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

From Java 9 :

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?

It is not a problem if the JDK referenced by the JAVA_HOME is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap JVM option with as value the path of the rt.jar of the target version.

An important thing to consider is that the source and the target version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.

To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.

How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?

For example, if your JAVA_HOME refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <compilerVersion>1.8</compilerVersion>      
        <fork>true</fork>
        <executable>D:\jdk1.8\bin\javac</executable>                
    </configuration>
</plugin>

You could have more details in examples with maven compiler plugin.

It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.

Why the compiler plugin is traced in the output at the execution of the Maven package goal even if you don't specify it in the pom.xml?

To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId : org.apache.maven.plugins) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.

In the output of the mvn help:effective-pom command, you could see the declaration of these core plugins in the <build><plugins> element, for example :

...
<plugin>
   <artifactId>maven-clean-plugin</artifactId>
   <version>2.5</version>
   <executions>
     <execution>
       <id>default-clean</id>
       <phase>clean</phase>
       <goals>
         <goal>clean</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.6</version>
   <executions>
     <execution>
       <id>default-testResources</id>
       <phase>process-test-resources</phase>
       <goals>
         <goal>testResources</goal>
       </goals>
     </execution>
     <execution>
       <id>default-resources</id>
       <phase>process-resources</phase>
       <goals>
         <goal>resources</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <executions>
     <execution>
       <id>default-compile</id>
       <phase>compile</phase>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
     <execution>
       <id>default-testCompile</id>
       <phase>test-compile</phase>
       <goals>
         <goal>testCompile</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
  ...

You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.

Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.

You can't get value when calling getJSON, only after response.

var myjson;
$.getJSON("http://127.0.0.1:8080/horizon-update", function(json){
    myjson = json;
});

agf's bytearray solution is workable, but if you find yourself needing to build up more complicated packets using datatypes other than bytes, you can try struct.pack(). http://docs.python.org/release/3.1.3/library/struct.html

The common approach is to call "cat /proc/net/netstat" as described here:

Android network stats

Thanks! to all above answers. I hope you have a .p12 file. Now, open terminal write following command. Set terminal to the path where you have put .12 file.

$ openssl pkcs12 -in yourCertifcate.p12 -out pemAPNSCert.pem -nodes
Enter Import Password: <Just enter your certificate password>
MAC verified OK

Now your .pem file is generated.

Verify .pem file First, open the .pem in a text editor to view its content. The certificate content should be in format as shown below. Make sure the pem file contains both Certificate content(from BEGIN CERTIFICATE to END CERTIFICATE) as well as Certificate Private Key (from BEGIN PRIVATE KEY to END PRIVATE KEY) :

> Bag Attributes
>     friendlyName: Apple Push Services:<Bundle ID>
>     localKeyID: <> subject=<>
> -----BEGIN CERTIFICATE-----
> 
> <Certificate Content>
> 
> -----END CERTIFICATE----- Bag Attributes
>     friendlyName: <>
>     localKeyID: <> Key Attributes: <No Attributes>
> -----BEGIN PRIVATE KEY-----
> 
> <Certificate Private Key>
> 
> -----END PRIVATE KEY-----

Also, you check the validity of the certificate by going to SSLShopper Certificate Decoder and paste the Certificate Content (from BEGIN CERTIFICATE to END CERTIFICATE) to get all the info about the certificate as shown below:

CONTAINS is for a Full Text Indexed field - if not, then use LIKE

label is an inline element so its width is equal to the width of the text it contains. The browser is actually displaying the label with text-align:center but since the label is only as wide as the text you don't notice.

The best thing to do is to apply a specific width to the label that is greater than the width of the content - this will give you the results you want.

Inside the function parameter list, char arr[] is absolutely equivalent to char *arr, so the pair of definitions and the pair of declarations are equivalent.

void function(char arr[]) { ... }
void function(char *arr)  { ... }

void function(char arr[]);
void function(char *arr);

The issue is the calling context. You provided a string literal to the function; string literals may not be modified; your function attempted to modify the string literal it was given; your program invoked undefined behaviour and crashed. All completely kosher.

Treat string literals as if they were static const char literal[] = "string literal"; and do not attempt to modify them.

I realize this is an old question and has been answered but this could help someone. In your activity

private ScheduledExecutorService scheduleTaskExecutor;

In onCreate

  scheduleTaskExecutor = Executors.newScheduledThreadPool(5);

    //Schedule a task to run every 5 seconds (or however long you want)
    scheduleTaskExecutor.scheduleAtFixedRate(new Runnable() {
        @Override
        public void run() {
            // Do stuff here!

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    // Do stuff to update UI here!
                    Toast.makeText(MainActivity.this, "Its been 5 seconds", Toast.LENGTH_SHORT).show();
                }
            });

        }
    }, 0, 5, TimeUnit.SECONDS); // or .MINUTES, .HOURS etc.

I'm using a newer version of the SPO Management Shell. For me to get the error to go away, I changed my Import-Module statement to use:

Import-Module Microsoft.Online.SharePoint.PowerShell -DisableNameChecking;

I also use the newer command:

Connect-SPOService

This works in MSSQL and MySQL:

SELECT *
FROM   Village
WHERE  CastleType LIKE '%foo%'; 

I do my own approach used for calling super with safety inside multiple inheritance scenario (I put all the code)

def safe_super(_class, _inst):
    """safe super call"""
    try:
        return getattr(super(_class, _inst), _inst.__fname__)
    except:
        return (lambda *x,**kx: None)


def with_name(function):
    def wrap(self, *args, **kwargs):
        self.__fname__ = function.__name__
        return function(self, *args, **kwargs)
return wrap

sample usage:

class A(object):

    def __init__():
        super(A, self).__init__()

    @with_name
    def test(self):
        print 'called from A\n'
        safe_super(A, self)()

class B(object):

    def __init__():
        super(B, self).__init__()

    @with_name
    def test(self):
        print 'called from B\n'
        safe_super(B, self)()

class C(A, B):

    def __init__():
        super(C, self).__init__()

    @with_name
    def test(self):
        print 'called from C\n'
        safe_super(C, self)()

testing it :

a = C()
a.test()

output:

called from C
called from A
called from B

Inside each @with_name decorated method you have access to self.__fname__ as the current function name.

Just to notify here. (from a newbee, keviv22)

Never and ever for the sake of your own good, name the folders or files with symbols like "-" or "_". If you did so, you may face few issues. like mine, say, though your command for importing is correct, you wont be able to successfully import the desired files which are available inside such named folders.

Invalid Folder namings as follows:

• Generic-Classes-Folder
• Generic_Classes_Folder

valid Folder namings for above:

• GenericClassesFolder or Genericclassesfolder or genericClassesFolder (or like this without any spaces or special symbols among the words)

What mistake I did:

consider the file structure.

Parent
   . __init__.py
   . Setup
     .. __init__.py
     .. Generic-Class-Folder
        ... __init__.py
        ... targetClass.py
   . Check
     .. __init__.py
     .. testFile.py

What I wanted to do?

• from testFile.py, I wanted to import the 'targetClass.py' file inside the Generic-Class-Folder file to use the function named "functionExecute" in 'targetClass.py' file

What command I did?

• from 'testFile.py', wrote command, from Core.Generic-Class-Folder.targetClass import functionExecute
• Got errors like SyntaxError: invalid syntax

Tried many searches and viewed many stackoverflow questions and unable to decide what went wrong. I cross checked my files multiple times, i used __init__.py file, inserted environment path and hugely worried what went wrong......

And after a long long long time, i figured this out while talking with a friend of mine. I am little stupid to use such naming conventions. I should never use space or special symbols to define a name for any folder or file. So, this is what I wanted to convey. Have a good day!

(sorry for the huge post over this... just letting my frustrations go.... :) Thanks!)

I used the code below and it worked for me.

String email="";
    SqlDataReader reader=cmd.ExecuteReader();
    if(reader.Read()){
        email=reader["Email"].ToString();
    }

String To=email;

/** Count max number of nonempty cells in sheet rows */
private int getColumnsCount(XSSFSheet xssfSheet) {
    int result = 0;
    Iterator<Row> rowIterator = xssfSheet.iterator();
    while (rowIterator.hasNext()) {
        Row row = rowIterator.next();
        List<Cell> cells = new ArrayList<>();
        Iterator<Cell> cellIterator = row.cellIterator();
        while (cellIterator.hasNext()) {
            cells.add(cellIterator.next());
        }
        for (int i = cells.size(); i >= 0; i--) {
            Cell cell = cells.get(i-1);
            if (cell.toString().trim().isEmpty()) {
                cells.remove(i-1);
            } else {
                result = cells.size() > result ? cells.size() : result;
                break;
            }
        }
    }
    return result;
}

you could submit all parameters with such naming:

params[0][topdiameter]
params[0][bottomdiameter]
params[1][topdiameter]
params[1][bottomdiameter]

then later you do something like this:

foreach ($_REQUEST['params'] as $item) {
    echo $item['topdiameter'];
    echo $item['bottomdiameter'];
}

I've found a great example using javax.websocket here:

http://www.programmingforliving.com/2013/08/jsr-356-java-api-for-websocket-client-api.html

Here the code based on the example linked above:

TestApp.java:

public class TestApp {

    public static void main(String[] args) {
        try {
            // open websocket
            final WebsocketClientEndpoint clientEndPoint = new WebsocketClientEndpoint(new URI("wss://real.okcoin.cn:10440/websocket/okcoinapi"));

            // add listener
            clientEndPoint.addMessageHandler(new WebsocketClientEndpoint.MessageHandler() {
                public void handleMessage(String message) {
                    System.out.println(message);
                }
            });

            // send message to websocket
            clientEndPoint.sendMessage("{'event':'addChannel','channel':'ok_btccny_ticker'}");

I had the same issue, the easiest way i found to insert the current date into a prepared statement is this one:

preparedStatement.setDate(1, new java.sql.Date(new java.util.Date().getTime()));

If it is VIM for Windows, you can do the following:

• enter your message following the presented guidelines
• press Esc to make sure you are out of the insert mode
• then type :wqEnter or ZZ.

Note that in VIM there are often several ways to do one thing. Here there is a slight difference though. :wqEnter always writes the current file before closing it, while ZZ, :xEnter, :xiEnter, :xitEnter, :exiEnter and :exitEnter only write it if the document is modified.
All these synonyms just have different numbers of keypresses.

In Oracle, you could use rownum to limit the number of rows returned. I am guessing similar construct exists in other SQLs as well. So, for the example you gave, you could limit the number of rows returned to 500001 and apply a count(*) then:

SELECT (case when cnt > 500000 then 500000 else cnt end) myCnt
FROM (SELECT count(*) cnt FROM table WHERE rownum<=500001)

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

new Long(Integer.longValue());

or

new Long(Integer.toString());

Also check out the attr() function of the CSS content attribute. It outputs a given attribute of the element as a text node. Use it like so:

<div class="Owner Joe" />

div:before {
  content: attr(class);
}

Or even with the new HTML5 custom data attributes:

<div data-employeename="Owner Joe" />

div:before {
  content: attr(data-employeename);
}

For PHP 7 in Ubuntu you can also do:

sudo apt-get install php7.0-pgsql

So, now you can do not uncomment lines in php.ini

UPD: I have a same error, so problem was not in driver. I changed my database.ini, but every time I saw an error. And I change database config in .env and errors gone.

I would just raise ValueError, unless you need a more specific exception..

def import_to_orm(name, save=False, recurse=False):
    if recurse and not save:
        raise ValueError("save must be True if recurse is True")

There's really no point in doing class BadValueError(ValueError):pass - your custom class is identical in use to ValueError, so why not use that?

To set radio button checked in edit mode in MVC razor view, please trying as follow:

<div class="col-lg-11 col-md-11">
     @Html.RadioButtonFor(m => m.Role, "1", Model.Role == 1 ? "checked" : string.Empty) 
     <span>Admin</span>
     @Html.RadioButtonFor(m => m.Role, "0", Model.Role == 0 ? "checked" : string.Empty)
     <span>User</span>
     @Html.HiddenFor(m => m.Role)
</div>

Hope it help!

Just found this, it works for me and I personally find it easier to read.

This will set the actual index just like gnarf's answer number 3 option.

// sets selected index of a select box the actual index of 0 
$("select#elem").attr('selectedIndex', 0);

This didn't used to work but does now... see bug: http://dev.jquery.com/ticket/1474

Addendum

As recommended in the comments use :

$("select#elem").prop('selectedIndex', 0);

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

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

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

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

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

and you can use it like:

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

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

How about this utility method?

public static <T> Stream<T> getReverseStream(List<T> list) {
    final ListIterator<T> listIt = list.listIterator(list.size());
    final Iterator<T> reverseIterator = new Iterator<T>() {
        @Override
        public boolean hasNext() {
            return listIt.hasPrevious();
        }

        @Override
        public T next() {
            return listIt.previous();
        }
    };
    return StreamSupport.stream(Spliterators.spliteratorUnknownSize(
            reverseIterator,
            Spliterator.ORDERED | Spliterator.IMMUTABLE), false);
}

Seems to work with all cases without duplication.

Well I did a bit of searching around the internet for you and I found this handy link.

You can adapt the sample code that is provided in the above link, courtesy of "swilliams" to your solution.

I was setting MIME type from .NET code as below -

File(generatedFileName, "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet")

My application generates excel using OpenXML SDK. This MIME type worked -

vnd.openxmlformats-officedocument.spreadsheetml.sheet

There are some good answers here already. But it's worthwhile to drive home the difference in parallelism offered:

• success() returns the original promise
• then() returns a new promise

The difference is then() drives sequential operations, since each call returns a new promise.

$http.get(/*...*/).
  then(function seqFunc1(response){/*...*/}).
  then(function seqFunc2(response){/*...*/})

1. $http.get()
2. seqFunc1()
3. seqFunc2()

success() drives parallel operations, since handlers are chained on the same promise.

$http(/*...*/).
  success(function parFunc1(data){/*...*/}).
  success(function parFunc2(data){/*...*/})

1. $http.get()
2. parFunc1(), parFunc2() in parallel

Try:

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff"

Then do another round of copy/paste of all the extensions (joined together with ; as above) for "All graphics types":

Filter = "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff|"
       + "All Graphics Types|*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff"

in my last version Visual Studio Code 1.30.2 it wil be change automatically into

$(function(){
    var _top = $(window).scrollTop();
    var _direction;
    $(window).scroll(function(){
        var _cur_top = $(window).scrollTop();
        if(_top < _cur_top)
        {
            _direction = 'down';
        }
        else
        {
            _direction = 'up';
        }
        _top = _cur_top;
        console.log(_direction);
    });
});

tags.map(&:name)

is The same as

tags.map{|tag| tag.name}

&:name just uses the symbol as the method name to be called.

I think this will happen if you'll use 'async defer' for (the file that contains the filter) while working with angularjs:

<script src="js/filter.js" type="text/javascript" async defer></script>

if you do, just remove 'async defer'.

Simply don't put whole commands in variables. You'll get into a lot of trouble trying to recover quoted arguments.

Also:

1. Avoid using all-capitals variable names in scripts. Easy way to shoot yourself on the foot.
2. Don't use backquotes, use $(...) instead, it nests better.

#! /bin/bash

if [ $# -ne 2 ]
then
    echo "Usage: $(basename $0) DIRECTORY BACKUP_DIRECTORY"
    exit 1
fi

directory=$1
backup_directory=$2
current_date=$(date +%Y-%m-%dT%H-%M-%S)
backup_file="${backup_directory}/${current_date}.backup"

tar cv "$directory" | openssl des3 -salt | split -b 1024m - "$backup_file"

I searched for a solution to parse very large files (gbs) line by line using a stream. All the third-party libraries and examples did not suit my needs since they processed the files not line by line (like 1 , 2 , 3 , 4 ..) or read the entire file to memory

The following solution can parse very large files, line by line using stream & pipe. For testing I used a 2.1 gb file with 17.000.000 records. Ram usage did not exceed 60 mb.

First, install the event-stream package:

npm install event-stream

Then:

var fs = require('fs')
    , es = require('event-stream');

var lineNr = 0;

var s = fs.createReadStream('very-large-file.csv')
    .pipe(es.split())
    .pipe(es.mapSync(function(line){

        // pause the readstream
        s.pause();

        lineNr += 1;

        // process line here and call s.resume() when rdy
        // function below was for logging memory usage
        logMemoryUsage(lineNr);

        // resume the readstream, possibly from a callback
        s.resume();
    })
    .on('error', function(err){
        console.log('Error while reading file.', err);
    })
    .on('end', function(){
        console.log('Read entire file.')
    })
);

Please let me know how it goes!

If you are dealing with a large df (40m x 700 in my case) it works much faster and memory savvy through iteration on columns with something like.

for col in df.columns:
    df[col][df[col] < 0] = 0

CharSequence is a readable sequence of char values which implements String. it has 4 methods

1. charAt(int index)
2. length()
3. subSequence(int start, int end)
4. toString()

Please refer documentation CharSequence documentation

Your question is based on assumption that the code which may throw NullPointerException is worse than the code which may not. This assumption is wrong. If you expect that your foobar is never null due to the program logic, it's much better to use Optional.of(foobar) as you will see a NullPointerException which will indicate that your program has a bug. If you use Optional.ofNullable(foobar) and the foobar happens to be null due to the bug, then your program will silently continue working incorrectly, which may be a bigger disaster. This way an error may occur much later and it would be much harder to understand at which point it went wrong.

I figured it out. I mistakenly added final keyword in activity declaration. Once I removed it everything works!

public  class SplashActivity extends AppCompatActivity {
...
}

Go via POSIXct and you want to set a TZ there -- here you see my (Chicago) default:

R> val <- 1352068320
R> as.POSIXct(val, origin="1970-01-01")
[1] "2012-11-04 22:32:00 CST"
R> as.Date(as.POSIXct(val, origin="1970-01-01"))
[1] "2012-11-05" 
R> 

Edit: A few years later, we can now use the anytime package:

R> library(anytime)
R> anytime(1352068320)
[1] "2012-11-04 16:32:00 CST"
R> anydate(1352068320)
[1] "2012-11-04"
R> 

Note how all this works without any format or origin arguments.

1. Download Maven from here.
2. Extract the tar.gz you just downloaded to the location you want (ex:/Users/admin/Maven).
3. Open the Terminal.
4. Type " cd " to go to your home folder.
5. Type "touch .bash_profile".
6. Type "open -e .bash_profile" to open .bash_profile in TextEdit.
7. Type the following in the TextEditor

alias mvn='/[Your file location]/apache-maven-x.x.x/bin/mvn'
export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdkx.x.x_xx.jdk/Contents/Home/

(Make sure there are no speech marks or apostrophe's) 8. Make sure you fill the required data (ex your file location and version number).

9. Save your changes
10. Type ". .bash_profile" to reload .bash_profile and update any functions you add. (*make sure you separate the dots with a single space).
11. Type mvn -version

Try to avoid what I have now decided to call Newbiecategoryaholism. When newcomers to Objective-C discover categories they often go hog wild, adding useful little categories to every class in existence ("What? i can add a method to convert a number to roman numerals to NSNumber rock on!").

Don't do this.

Your code will be more portable and easier to understand with out dozens of little category methods sprinkled on top of two dozen foundation classes.

Most of the time when you really think you need a category method to help streamline some code you'll find you never end up reusing the method.

There are other dangers too, unless you're namespacing your category methods (and who besides the utterly insane ddribin is?) there is a chance that Apple, or a plugin, or something else running in your address space will also define the same category method with the same name with a slightly different side effect....

OK. Now that you've been warned, ignore the "don't do this part". But exercise extreme restraint.

You can use foreignobject for more control and placing rich HTML content over rect or circle

    <svg width="250" height="250" xmlns="http://www.w3.org/2000/svg">_x000D_
        <rect x="0" y="0" width="250" height="250" fill="aquamarine" />_x000D_

            <body xmlns="http://www.w3.org/1999/xhtml">_x000D_
                <div>Here is a long text that runs more than one line and works as a paragraph</div>_x000D_
                <br />_x000D_
                <div>This is <u>UNDER LINE</u> one</div>_x000D_

                <div>This is <b>BOLD</b> one</div>_x000D_

You want to add a tuple, not a list:

>>> a=set('abcde')
>>> a
set(['a', 'c', 'b', 'e', 'd'])
>>> l=['f','g']
>>> l
['f', 'g']
>>> t = tuple(l)
>>> t
('f', 'g')
>>> a.add(t)
>>> a
set(['a', 'c', 'b', 'e', 'd', ('f', 'g')])

If you have a list, you can convert to the tuple, as shown above. A tuple is immutable, so it can be added to the set.

You can simply export the table with a query clause using datapump and import it back with table_exists_action=replace clause. Its will drop and recreate your table and take very less time. Please read about it before implementing.

For some picky web services, the request needs to have the content type set to JSON and the body to be a JSON string. For example:

Invoke-WebRequest -UseBasicParsing http://example.com/service -ContentType "application/json" -Method POST -Body "{ 'ItemID':3661515, 'Name':'test'}"

or the equivalent for XML, etc.

here the writer suggests this:

public boolean isOnline() {
    Runtime runtime = Runtime.getRuntime();
    try {
        Process ipProcess = runtime.exec("/system/bin/ping -c 1 8.8.8.8");
        int     exitValue = ipProcess.waitFor();
        return (exitValue == 0);
    } catch (IOException | InterruptedException e) { e.printStackTrace(); }
    return false;
}

Possible Questions

• Is this really fast enough?Yes, very fast!
• Couldn’t I just ping my own page, which I want to request anyways? Sure! You could even check both, if you want to differentiate between “internet connection available” and your own servers beeing reachable What if the DNS is down? Google DNS (e.g. 8.8.8.8) is the largest public DNS service in the world. As of 2013 it serves 130 billion requests a day. Let ‘s just say, your app not responding would probably not be the talk of the day.

read the link. its seems very good

EDIT: in my exp of using it, it's not as fast as this method:

public boolean isOnline() {
    NetworkInfo netInfo = connectivityManager.getActiveNetworkInfo();
    return netInfo != null && netInfo.isConnectedOrConnecting();
}

they are a bit different but in the functionality for just checking the connection to internet the first method may become slow due to the connection variables.

EDIT: The below answer no longer works see here

If the file you try to recover has Content-Encoding: gzip in the header section, and you are using linux (or as in my case, you have Cygwin installed) you can do the following:

1. visit chrome://view-http-cache/ and click the page you want to recover
2. copy the last (fourth) section of the page verbatim to a text file (say: a.txt)
3. xxd -r a.txt| gzip -d

Note that other answers suggest passing -p option to xxd - I had troubles with that presumably because the fourth section of the cache is not in the "postscript plain hexdump style" but in a "default style".

It also does not seem necessary to replace double spaces with a single space, as chrome_xxd.py is doing (in case it is necessary you can use sed 's/ / /g' for that).

Windows -- > showView --> variable

or you can reset the perspective

windows -- > preferences -- > perspective --> restore Defaults

For PHPStorm 2020.3.2 on ubuntu inorder to reset expiration license, you should run following commands:

sudo rm ~/.config/JetBrains/PhpStorm2020.3/options/other.xml 
sudo rm ~/.config/JetBrains/PhpStorm2020.3/eval/*          
sudo rm -rf .java/.userPrefs

Without a bit of information about what files are in your repository (pure source code, images, executables, ...), it's a bit hard to answer the question :)

Beside this, I'll consider that you're willing to default to LF as line endings in your working directory because you're willing to make sure that text files have LF line endings in your .git repository wether you work on Windows or Linux. Indeed better safe than sorry....

However, there's a better alternative: Benefit from LF line endings in your Linux workdir, CRLF line endings in your Windows workdir AND LF line endings in your repository.

As you're partially working on Linux and Windows, make sure core.eol is set to native and core.autocrlf is set to true.

Then, replace the content of your .gitattributes file with the following

* text=auto

This will let Git handle the automagic line endings conversion for you, on commits and checkouts. Binary files won't be altered, files detected as being text files will see the line endings converted on the fly.

However, as you know the content of your repository, you may give Git a hand and help him detect text files from binary files.

Provided you work on a C based image processing project, replace the content of your .gitattributes file with the following

* text=auto
*.txt text
*.c text
*.h text
*.jpg binary

This will make sure files which extension is c, h, or txt will be stored with LF line endings in your repo and will have native line endings in the working directory. Jpeg files won't be touched. All of the others will be benefit from the same automagic filtering as seen above.

In order to get a get a deeper understanding of the inner details of all this, I'd suggest you to dive into this very good post "Mind the end of your line" from Tim Clem, a Githubber.

As a real world example, you can also peek at this commit where those changes to a .gitattributes file are demonstrated.

UPDATE to the answer considering the following comment

I actually don't want CRLF in my Windows directories, because my Linux environment is actually a VirtualBox sharing the Windows directory

Makes sense. Thanks for the clarification. In this specific context, the .gitattributes file by itself won't be enough.

Run the following commands against your repository

$ git config core.eol lf
$ git config core.autocrlf input

As your repository is shared between your Linux and Windows environment, this will update the local config file for both environment. core.eol will make sure text files bear LF line endings on checkouts. core.autocrlf will ensure potential CRLF in text files (resulting from a copy/paste operation for instance) will be converted to LF in your repository.

Optionally, you can help Git distinguish what is a text file by creating a .gitattributes file containing something similar to the following:

# Autodetect text files
* text=auto

# ...Unless the name matches the following
# overriding patterns

# Definitively text files 
*.txt text
*.c text
*.h text

# Ensure those won't be messed up with
*.jpg binary
*.data binary

If you decided to create a .gitattributes file, commit it.

Lastly, ensure git status mentions "nothing to commit (working directory clean)", then perform the following operation

$ git checkout-index --force --all

This will recreate your files in your working directory, taking into account your config changes and the .gitattributes file and replacing any potential overlooked CRLF in your text files.

Once this is done, every text file in your working directory WILL bear LF line endings and git status should still consider the workdir as clean.

If you really to assign values (as opposed to initialize), you can do it like this:

 GLfloat coordinates[8]; 
 static const GLfloat coordinates_defaults[8] = {1.0f, 0.0f, 1.0f ....};
 ... 
 memcpy(coordinates, coordinates_defaults, sizeof(coordinates_defaults));

 return coordinates; 

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

It is possible to use na.omit for data.table:

na.omit(data, cols = c("x", "z"))

SELinux prevents Apache (and therefore all Apache modules) from making remote connections by default.

# setsebool -P httpd_can_network_connect=1

Try this:

if (rs != null && rs.first()) {
    do {
        count = rs.getInt(1);
    } while (rs.next());
}

/.*/ works great if there are no line breaks. If it has to match line breaks, here are some solutions:

You can use the command time /t for the time and date /t for the date, here is an example:

@echo off
time /t >%tmp%\time.tmp
date /t >%tmp%\date.tmp
set ttime=<%tmp%\time.tmp
set tdate=<%tmp%\date.tmp
del /f /q %tmp%\time.tmp
del /f /q %tmp%\date.tmp
echo Time: %ttime%
echo Date: %tdate%
pause >nul

You can also use the built in variables %time% and %date%, here is another example:

@echo off
echo Time: %time:~0,5%
echo Date: %date%
pause >nul

Each version of Visual Studio prior to Visual Studio 2010 is tied to a specific .NET framework. (VS2008 is .NET 3.5, VS2005 is .NET 2.0, VS2003 is .NET1.1) Visual Studio 2010 and beyond allow for targeting of prior framework versions but cannot be used for future releases. You must use Visual Studio 2012 in order to utilize .NET 4.5.

First argument in update method is SyntheticEvent object that contains common properties and methods to any event, it is not reference to React component where there is property props.

if you need pass argument to update method you can do it like this

onClick={ (e) => this.props.onClick(e, 'home', 'Home') }

and get these arguments inside update method

update(e, space, txt){
   console.log(e.target, space, txt);
}

Example

event.target gives you the native DOMNode, then you need to use the regular DOM APIs to access attributes. For instance getAttribute or dataset

<button 
  data-space="home" 
  className="home" 
  data-txt="Home" 
  onClick={ this.props.onClick } 
/> 
  Button
</button>

onClick(e) {
   console.log(e.target.dataset.txt, e.target.dataset.space);
}

Example

One easy trick that can help with most deadlocks is sorting the operations in a specific order.

You get a deadlock when two transactions are trying to lock two locks at opposite orders, ie:

• connection 1: locks key(1), locks key(2);
• connection 2: locks key(2), locks key(1);

If both run at the same time, connection 1 will lock key(1), connection 2 will lock key(2) and each connection will wait for the other to release the key -> deadlock.

Now, if you changed your queries such that the connections would lock the keys at the same order, ie:

• connection 1: locks key(1), locks key(2);
• connection 2: locks key(1), locks key(2);

it will be impossible to get a deadlock.

So this is what I suggest:

1. Make sure you have no other queries that lock access more than one key at a time except for the delete statement. if you do (and I suspect you do), order their WHERE in (k1,k2,..kn) in ascending order.

2. Fix your delete statement to work in ascending order:

Change

DELETE FROM onlineusers 
WHERE datetime <= now() - INTERVAL 900 SECOND

To

DELETE FROM onlineusers 
WHERE id IN (
    SELECT id FROM onlineusers
    WHERE datetime <= now() - INTERVAL 900 SECOND 
    ORDER BY id
) u;

Another thing to keep in mind is that mysql documentation suggest that in case of a deadlock the client should retry automatically. you can add this logic to your client code. (Say, 3 retries on this particular error before giving up).

There does exist a split function based on regular expressions. It's not listed in the tutorial, but it is listed on the language manual on the wiki:

split(string str, string pat)
   Split str around pat (pat is a regular expression) 

In your case, the delimiter "|" has a special meaning as a regular expression, so it should be referred to as "\\|".

You can achieve this with the background-size property, which is now supported by most browsers.

To scale the background image to fit inside the div:

background-size: contain;

To scale the background image to cover the whole div:

background-size: cover;

JSFiddle example

There also exists a filter for IE 5.5+ support, as well as vendor prefixes for some older browsers.

As this is a very frequently asked question, I wanted to take the time and effort to explain the ViewPager with multiple Fragments and Layouts in detail. Here you go.

ViewPager with multiple Fragments and Layout files - How To

The following is a complete example of how to implement a ViewPager with different fragment Types and different layout files.

In this case, I have 3 Fragment classes, and a different layout file for each class. In order to keep things simple, the fragment-layouts only differ in their background color. Of course, any layout-file can be used for the Fragments.

FirstFragment.java has a orange background layout, SecondFragment.java has a green background layout and ThirdFragment.java has a red background layout. Furthermore, each Fragment displays a different text, depending on which class it is from and which instance it is.

Also be aware that I am using the support-library's Fragment: android.support.v4.app.Fragment

MainActivity.java (Initializes the Viewpager and has the adapter for it as an inner class). Again have a look at the imports. I am using the android.support.v4 package.

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

public class MainActivity extends FragmentActivity {

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

        ViewPager pager = (ViewPager) findViewById(R.id.viewPager);
        pager.setAdapter(new MyPagerAdapter(getSupportFragmentManager()));
    }

    private class MyPagerAdapter extends FragmentPagerAdapter {

        public MyPagerAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int pos) {
            switch(pos) {

            case 0: return FirstFragment.newInstance("FirstFragment, Instance 1");
            case 1: return SecondFragment.newInstance("SecondFragment, Instance 1");
            case 2: return ThirdFragment.newInstance("ThirdFragment, Instance 1");
            case 3: return ThirdFragment.newInstance("ThirdFragment, Instance 2");
            case 4: return ThirdFragment.newInstance("ThirdFragment, Instance 3");
            default: return ThirdFragment.newInstance("ThirdFragment, Default");
            }
        }

        @Override
        public int getCount() {
            return 5;
        }       
    }
}

activity_main.xml (The MainActivitys .xml file) - a simple layout file, only containing the ViewPager that fills the whole screen.

<android.support.v4.view.ViewPager
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/viewPager"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    />

The Fragment classes, FirstFragment.java import android.support.v4.app.Fragment;

public class FirstFragment extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.first_frag, container, false);

        TextView tv = (TextView) v.findViewById(R.id.tvFragFirst);
        tv.setText(getArguments().getString("msg"));

        return v;
    }

    public static FirstFragment newInstance(String text) {

        FirstFragment f = new FirstFragment();
        Bundle b = new Bundle();
        b.putString("msg", text);

        f.setArguments(b);

        return f;
    }
}

first_frag.xml

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

    <TextView
        android:id="@+id/tvFragFirst"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textSize="26dp"
        android:text="TextView" />
</RelativeLayout>

SecondFragment.java

public class SecondFragment extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.second_frag, container, false);

    TextView tv = (TextView) v.findViewById(R.id.tvFragSecond);
    tv.setText(getArguments().getString("msg"));

    return v;
}

public static SecondFragment newInstance(String text) {

    SecondFragment f = new SecondFragment();
    Bundle b = new Bundle();
    b.putString("msg", text);

    f.setArguments(b);

    return f;
}
}

second_frag.xml

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

    <TextView
        android:id="@+id/tvFragSecond"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textSize="26dp"
        android:text="TextView" />

</RelativeLayout>

ThirdFragment.java

public class ThirdFragment extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.third_frag, container, false);

    TextView tv = (TextView) v.findViewById(R.id.tvFragThird);      
    tv.setText(getArguments().getString("msg"));

    return v;
}

public static ThirdFragment newInstance(String text) {

    ThirdFragment f = new ThirdFragment();
    Bundle b = new Bundle();
    b.putString("msg", text);

    f.setArguments(b);

    return f;
}
}

third_frag.xml

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

    <TextView
        android:id="@+id/tvFragThird"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:textSize="26dp"
        android:text="TextView" />

</RelativeLayout>

The end result is the following:

The Viewpager holds 5 Fragments, Fragments 1 is of type FirstFragment, and displays the first_frag.xml layout, Fragment 2 is of type SecondFragment and displays the second_frag.xml, and Fragment 3-5 are of type ThirdFragment and all display the third_frag.xml.

Above you can see the 5 Fragments between which can be switched via swipe to the left or right. Only one Fragment can be displayed at the same time of course.

Last but not least:

I would recommend that you use an empty constructor in each of your Fragment classes.

Instead of handing over potential parameters via constructor, use the newInstance(...) method and the Bundle for handing over parameters.

This way if detached and re-attached the object state can be stored through the arguments. Much like Bundles attached to Intents.

You can use the os Module:

var os = require("os");
os.hostname();

See http://nodejs.org/docs/latest/api/os.html#os_os_hostname

Caveats:

1. if you can work with the IP address -- Machines may have several Network Cards and unless you specify it node will listen on all of them, so you don't know on which NIC the request came in, before it comes in.

2. Hostname is a DNS matter -- Don't forget that several DNS aliases can point to the same machine.

Another bug in Java. I seldom find them, only my second in my 10 year career. This is my solution, as others have mentioned. I have nether used System.gc(). But here, in my case, it is absolutely crucial. Weird? YES!

finally
{
    try
    {
        in.close();
        in = null;
        out.flush();
        out.close();
        out = null;
        System.gc();
    }
    catch (IOException e)
    {
        logger.error(e.getMessage());
        e.printStackTrace();
    }
}

The console is printing the representation, not the string itself.

If you prefix with print, you'll get what you expect.

See this question for details about the difference between a string and the string's representation. Super-simplified, the representation is what you'd type in source code to get that string.

Never hardcode this location. Use the environment variables %ProgramFiles% or %ProgramFiles(x86)%.

When specifying these, always quote because Microsoft may have put spaces or other special characters in them.

"%ProgramFiles%\theapp\app.exe"
"%ProgramFiles(x86)%\theapp\app.exe"

In addition, the directory might be expressed in a language you do not know. http://www.samlogic.net/articles/program-files-folder-different-languages.htm

>set|findstr /i /r ".*program.*="
CommonProgramFiles=C:\Program Files\Common Files
CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files
CommonProgramW6432=C:\Program Files\Common Files
ProgramData=C:\ProgramData
ProgramFiles=C:\Program Files
ProgramFiles(x86)=C:\Program Files (x86)
ProgramW6432=C:\Program Files

Use these commands to find the values on a machine. DO NOT hardcode them into a program or .bat or .cmd file script. Use the variable.

set | findstr /R "^Program"
set | findstr /R "^Common"

I had a very similar error message as you, although listing a particular file:

$ make
make: execvp: ../HoughLineExtractor/houghlineextractor.hh: Permission denied
make: *** [../HoughLineAccumulator/houghlineaccumulator.o] Error 127

$ sudo make
make: execvp: ../HoughLineExtractor/houghlineextractor.hh: Permission denied
make: *** [../HoughLineAccumulator/houghlineaccumulator.o] Error 127

In my case, I forgot to add a trailing slash to indicate continuation of the line as shown:

${LINEDETECTOR_OBJECTS}:\
    ../HoughLineAccumulator/houghlineaccumulator.hh  # <-- missing slash!!
    ../HoughLineExtractor/houghlineextractor.hh

Hope that helps someone else who lands here from a search engine.

Try this below code for binding html through attr

.directive('dynamic', function ($compile) {
    return {
      restrict: 'A',
      replace: true,
      scope: { dynamic: '=dynamic'},
      link: function postLink(scope, element, attrs) {
        scope.$watch( 'attrs.dynamic' , function(html){
          element.html(scope.dynamic);
          $compile(element.contents())(scope);
        });
      }
    };
  });

Try this element.html(scope.dynamic); than element.html(attr.dynamic);

Depending on what you're doing you might like to take a look at GMP (gmplib.org) which is a high-performance multi-precision library. To use it in Java you need JNI wrappers around the binary library.

See some of the Alioth Shootout code for an example of using it instead of BigInteger to calculate Pi to an arbitrary number of digits.

My problem on git was the project permission configuration. I've fixed it by enable the "Container registry" in settings->general->Visibility, project features, permissions and enable Container Registry for my project (link):

As documented in ?legend you do this like so:

plot(1:10,type = "n")
abline(v=seq(1,10,1), col='grey', lty='dotted')
legend(1, 5, "This legend text should not be disturbed by the dotted grey lines,\nbut the plotted dots should still be visible",box.lwd = 0,box.col = "white",bg = "white")
points(1:10,1:10)

Line breaks are achieved with the new line character \n. Making the points still visible is done simply by changing the order of plotting. Remember that plotting in R is like drawing on a piece of paper: each thing you plot will be placed on top of whatever's currently there.

Note that the legend text is cut off because I made the plot dimensions smaller (windows.options does not exist on all R platforms).

another workaround:

var myarray = [];
$("#test").click(function() {
    myarray[index]=$("#drop").val();
    alert(myarray);
});

i wanted to add all checked checkbox to array. so example, if .each is used:

var vpp = [];
var incr=0;
$('.prsn').each(function(idx) {
   if (this.checked) {
       var p=$('.pp').eq(idx).val();
       vpp[incr]=(p);
       incr++;
   }
});
//do what ever with vpp array;

Please check if you have already close the database connection or not. In my case i was getting the error because the connection was close in upper line.

ansible-playbook release.yml -e "version=1.23.45 other_variable=foo"

I recommend using the incredible requests module.

http://docs.python-requests.org/en/v0.10.7/user/quickstart/#custom-headers

url = 'https://api.github.com/some/endpoint'
payload = {'some': 'data'}
headers = {'content-type': 'application/json'}

response = requests.post(url, data=json.dumps(payload), headers=headers)

It is an old question, but I just ran into it. Type.GetMethod(string name) will throw an AmbiguousMatchException if there is more than one method with that name, so we better handle that case

public static bool HasMethod(this object objectToCheck, string methodName)
{
    try
    {
        var type = objectToCheck.GetType();
        return type.GetMethod(methodName) != null;
    }
    catch(AmbiguousMatchException)
    {
        // ambiguous means there is more than one result,
        // which means: a method with that name does exist
        return true;
    }
} 

Use - (Negative sign) along with position of element, example if 3rd element is to be removed use it as your_list[-3]

Input

my_list <- list(a = 3, b = 3, c = 4, d = "Hello", e = NA)
my_list
# $`a`
# [1] 3

# $b
# [1] 3

# $c
# [1] 4

# $d
# [1] "Hello"

# $e
# [1] NA

Remove single element from list

 my_list[-3]
 # $`a`
 # [1] 3

 # $b
 # [1] 3

 # $d
 # [1] "Hello"

 # $e
 [1] NA

Remove multiple elements from list

 my_list[c(-1,-3,-2)]
 # $`d`
 # [1] "Hello"

 # $e
 # [1] NA

 my_list[c(-3:-5)]
 # $`a`
 # [1] 3

 # $b
 # [1] 3

 my_list[-seq(1:2)]
 # $`c`
 # [1] 4

 # $d
 # [1] "Hello"

 # $e
 # [1] NA

in some cases you might need an override of onLoadResource if you get a redirect which doesn't trigger the url loading method. in this case i tried the following:

@Override
public void onLoadResource(WebView view, String url)
{
    if (url.equals("http://redirectexample.com"))
    {
        //do your own thing here
    }
    else
    {
        super.onLoadResource(view, url);
    }           
}

Using int.TryParse will yield these results:

        var shouldBeInt = 3;

        var shouldntBeInt = 3.1415;

        var iDontWantThisToBeInt = 3.000f;

        Console.WriteLine(int.TryParse(shouldBeInt.ToString(), out int parser)); // true

        Console.WriteLine(int.TryParse(shouldntBeInt.ToString(), out parser)); // false

        Console.WriteLine(int.TryParse(iDontWantThisToBeInt.ToString(), out parser)); // true, even if I don't want this to be int

        Console.WriteLine(int.TryParse("3.1415", out  parser)); // false

        Console.WriteLine(int.TryParse("3.0000", out parser)); // false

        Console.WriteLine(int.TryParse("3", out parser)); // true

        Console.ReadKey();

Disclaimer: Avoid !important at all cost.

This is a dirty, dirty hack, but you can override an !important, without an !important, by using an (infinitely looping or very long lasting) animation on the property you're trying to override the importants on.

@keyframes forceYellow {_x000D_
  from {_x000D_
    background-color: yellow;_x000D_
  }_x000D_
  to {_x000D_
    background-color: yellow;_x000D_
  }_x000D_
}_x000D_
_x000D_
div {_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  margin: 0 auto;_x000D_
  background: red !important;_x000D_
  animation: 1s linear infinite forceYellow;_x000D_
}

<div></div>

Another way to extend (specifically meaning, add new methods, not change existing ones) classes, even built-in ones, is to use a preprocessor that adds the ability to extend out of/above the scope of Python itself, converting the extension to normal Python syntax before Python actually gets to see it.

I've done this to extend Python 2's str() class, for instance. str() is a particularly interesting target because of the implicit linkage to quoted data such as 'this' and 'that'.

Here's some extending code, where the only added non-Python syntax is the extend:testDottedQuad bit:

extend:testDottedQuad
def testDottedQuad(strObject):
    if not isinstance(strObject, basestring): return False
    listStrings = strObject.split('.')
    if len(listStrings) != 4: return False
    for strNum in listStrings:
        try:    val = int(strNum)
        except: return False
        if val < 0: return False
        if val > 255: return False
    return True

After which I can write in the code fed to the preprocessor:

if '192.168.1.100'.testDottedQuad():
    doSomething()

dq = '216.126.621.5'
if not dq.testDottedQuad():
    throwWarning();

The preprocessor eats that, spits out normal Python without monkeypatching, and Python does what I intended it to do.

Just as a c preprocessor adds functionality to c, so too can a Python preprocessor add functionality to Python.

My preprocessor implementation is too large for a stack overflow answer, but for those who might be interested, it is here on GitHub.

final class PagingFlowLayout: UICollectionViewFlowLayout {
    private var currentIndex = 0

    override func targetContentOffset(forProposedContentOffset proposedContentOffset: CGPoint, withScrollingVelocity velocity: CGPoint) -> CGPoint {
        let count = collectionView!.numberOfItems(inSection: 0)
        let currentAttribute = layoutAttributesForItem(
            at: IndexPath(item: currentIndex, section: 0)
            ) ?? UICollectionViewLayoutAttributes()

        let direction = proposedContentOffset.x > currentAttribute.frame.minX
        if collectionView!.contentOffset.x + collectionView!.bounds.width < collectionView!.contentSize.width || currentIndex < count - 1 {
            currentIndex += direction ? 1 : -1
            currentIndex = max(min(currentIndex, count - 1), 0)
        }

        let indexPath = IndexPath(item: currentIndex, section: 0)
        let closestAttribute = layoutAttributesForItem(at: indexPath) ?? UICollectionViewLayoutAttributes()

        let centerOffset = collectionView!.bounds.size.width / 2
        return CGPoint(x: closestAttribute.center.x - centerOffset, y: 0)
    }
}

You should put your processing into the class constructor or an OnInit hook method.

When you get the error message, you have the option to click on "Debug": this will lead you to the line where the error occurred. The Dark Canuck seems to be right, and I guess the error occurs on the line:

Sheets("Sheet1").protect Password:="btfd"

because most probably the "Sheet1" does not exist. However, if you say "It works fine, but when I save the file I get the message: run-time error '9': subscription out of range" it makes me think the error occurs on the second line:

ActiveWorkbook.Save

Could you please check this by pressing the Debug button first? And most important, as Gordon Bell says, why are you using a macro to protect a workbook?

The better option is create a new table copy the rows to the destination table, drop the actual table and rename the newly created table . This method is good for small tables,

Here's a bug report on the feature you're requesting.

It's status is "reviewed" but I don't believe it's been implemented yet.

Sure, the [::] is the extended slice operator. It allows you to take substrings. Basically, it works by specifying which elements you want as [begin:end:step], and it works for all sequences. Two neat things about it:

• You can omit one or more of the elements and it does "the right thing"
• Negative numbers for begin, end, and step have meaning

For begin and end, if you give a negative number, it means to count from the end of the sequence. For instance, if I have a list:

l = [1,2,3]

Then l[-1] is 3, l[-2] is 2, and l[-3] is 1.

For the step argument, a negative number means to work backwards through the sequence. So for a list::

l = [1,2,3,4,5,6,7,8,9,10]

You could write l[::-1] which basically means to use a step size of -1 while reading through the list. Python will "do the right thing" when filling in the start and stop so it iterates through the list backwards and gives you [10,9,8,7,6,5,4,3,2,1].

I've given the examples with lists, but strings are just another sequence and work the same way. So a[::-1] means to build a string by joining the characters you get by walking backwards through the string.

yum update

helped me out. After I had

wget: symbol lookup error: wget: undefined symbol: psl_latest

just call the finish() in the method you would like to end the activity in, for example when you use the onCreate() method, in the end of the method, just add finish() and you will see the activity ends as soon as it is created!

Private constructor and static methods on a class marked as final.

On a Mac (pdftex) I managed to include a png file simply with \includegraphics[width=1.2\textwidth]{filename.png}. But in order for that to work I had to comment out the following 2 packages:

%\usepackage[dvips]{epsfig}

%\usepackage[dvips]{graphicx}

...and simply use package graphicx:

\usepackage{graphicx}

It seems [dvips] is problematic when used with pdftex.

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

items is one attribute of dict object.maybe you can try

qs[0].items()

Warning: if you want to load the 'monkey patch' or 'open class' from your 'lib' folder, don't use the 'autoload' approach!!!

• "config.autoload_paths" approach: only works if you are loading a class that defined only in ONE place. If some class has been already defined somewhere else, then you can't load it again by this approach.

• "config/initializer/load_rb_file.rb" approach: always works! whatever the target class is a new class or an "open class" or "monkey patch" for existing class, it always works!

For more details , see: https://stackoverflow.com/a/6797707/445908

I had the same problem but I solved it differently. I don't know if it's a good way of doing it, but it works great for what I need.

I used @Inject on the constructor of the child component, like this:

import { Component, OnInit, Inject } from '@angular/core';
import { ParentComponent } from '../views/parent/parent.component';

export class ChildComponent{
    constructor(@Inject(ParentComponent) private parent: ParentComponent){

    }

    someMethod(){
        this.parent.aPublicProperty = 2;
    }
}

This worked for me, you only need to declare the method or property you want to call as public.

In my case, the AppComponent handles the routing, and I'm using badges in the menu items to alert the user that new unread messages are available. So everytime a user reads a message, I want that counter to refresh, so I call the refresh method so that the number at the menu nav gets updated with the new value. This is probably not the best way but I like it for its simplicity.

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

I just use this for add a image to clipboard in windows.

If you use the new querySelectorAll you can call forEach directly.

document.querySelectorAll('.edit').forEach(function(button) {
    // Now do something with my button
});

Per the comment below. nodeLists do not have a forEach function.

If using this with babel you can add Array.from and it will convert non node lists to a forEach array. Array.from does not work natively in browsers below and including IE 11.

Array.from(document.querySelectorAll('.edit')).forEach(function(button) {
    // Now do something with my button
});

At our meetup last night I discovered another way to handle node lists not having forEach

[...document.querySelectorAll('.edit')].forEach(function(button) {
    // Now do something with my button
});

Browser Support for [...]

You need to give the WebClient object the credentials. Something like this...

 WebClient client = new WebClient();
 client.Credentials = new NetworkCredential("username", "password");

All those results generate garbage in a zealous attempt to handle more than two arguments. I'd be curious to see how they perform compared to good 'ol:

def max (a,b)
  a>b ? a : b
end

which is, by-the-way, my official answer to your question.

The column of the first matrix and the row of the second matrix should be equal and the order should be like this only

column of first matrix = row of second matrix

and do not follow the below step

row of first matrix  = column of second matrix

it will throw an error

Since id is an attribute don't create an id element, just do this:

myPara.setAttribute("id", "id_you_like");

Not a lot to go on there, but I think what you're looking for is to flip the width and max-width values:

#container2 {
  width: 90%;
  max-width: 960px;
  /* etc, etc... */
}

That'll give you a container that's 90% of the width of the available space, up to a maximum of 960px, but that's dependent on its container being resizable itself. Responsive design is a whole big ball of wax though, so this doesn't even scratch the surface.

Simple Server-Side Fix

Note: DO NOT USE "socketio" package... use "socket.io" instead. "socketio" is out of date. Some users seem to be using the wrong package.

socket.io v3

docs: https://socket.io/docs/v3/handling-cors/

cors options: https://www.npmjs.com/package/cors

const io = require('socket.io')(server, {
  cors: {
    origin: '*',
  }
});

socket.io < v3

const io = require('socket.io')(server, { origins: '*:*'});

or

io.set('origins', '*:*');

or

io.origins('*:*') // for latest version

* alone doesn't work which took me down rabbit holes.

You can only close windows/tabs that you create yourself. That is, you cannot programmatically close a window/tab that the user creates.

For example, if you create a window with window.open() you can close it with window.close().

Without CSS, you basically are stuck with using an image tag. Basically make an image of the text and add the underline. That basically means your page is useless to a screen reader.

With CSS, it is simple.

HTML:

<u class="dotted">I like cheese</u>

CSS:

u.dotted{
  border-bottom: 1px dashed #999;
  text-decoration: none; 
}

Running Example

Example page

<!DOCTYPE HTML>
<html>
<head>
    <style>
        u.dotted{
          border-bottom: 1px dashed #999;
          text-decoration: none; 
        }
    </style>
</head>
<body>
    <u class="dotted">I like cheese</u>
</body>
</html>

Use:

if (start-process filename1.exe) {} else {start-process filename2.exe}

It's a little longer than "&&", but it accomplishes the same thing without scripting and is not too hard to remember.
