If it instead returned Option[QueueObject] you could use a construct like getObject.foreach { QueueManager.add }. You can wrap it right inline with Option(getObject).foreach ... because Option[QueueObject](null) is None.

The following from Paul Tarjan worked for me,

var data = { 'user_ids[]' : []};
$(":checked").each(function() {
  data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);

but I had multiple forms on my page and it pulled checked boxes from all forms, so I made the following modification so it only pulled from one form,

var data = { 'user_ids[]' : []};
$('#name_of_your_form input[name="user_ids[]"]:checked').each(function() {
  data['user_ids[]'].push($(this).val());
});
$.post("ajax.php", data);

Just change name_of_your_form to the name of your form.

I'll also mention that if a user doesn't check any boxes then no array isset in PHP. I needed to know if a user unchecked all the boxes, so I added the following to the form,

<input style="display:none;" type="checkbox" name="user_ids[]" value="none" checked="checked"></input>

This way if no boxes are checked, it will still set the array with a value of "none".

The Google Feed API is officially deprecated and doesn't work anymore!

No need for a whole plugin. This will return your RSS as a JSON object to a callback function:

Pass the sheet name with the Range parameter of the DoCmd.TransferSpreadsheet Method. See the box titled "Worksheets in the Range Parameter" near the bottom of that page.

This code imports from a sheet named "temp" in a workbook named "temp.xls", and stores the data in a table named "tblFromExcel".

Dim strXls As String
strXls = CurrentProject.Path & Chr(92) & "temp.xls"
DoCmd.TransferSpreadsheet acImport, , "tblFromExcel", _
    strXls, True, "temp!"

<p>
   <textarea id="msgc" onkeyup="cnt(event)" rows="1" cols="1"></textarea> 
</p> 
<p id="valmess2" style="color:red" ></p>

function cnt(event)
{ 
 document.getElementById("valmess2").innerHTML=""; // init and clear if b < max     
allowed character 

 a = document.getElementById("msgc").value; 
 b = a.length; 
 if (b > 400)
  { 
   document.getElementById("valmess2").innerHTML="the max length of 400 characters is 
reached, you typed in  " + b + "characters"; 
  } 
}

maxlength is only valid for HTML5. For HTML/XHTML you have to use JavaScript and/or PHP. With PHP you can use strlen for example.This example indicates only the max length, it's NOT blocking the input.

Move your map variable into a scope where the event listener can use it. You are creating the map inside your initialize() function and nothing else can use it when created that way.

var map; //<-- This is now available to both event listeners and the initialize() function
function initialize() {
  var mapOptions = {
   center: new google.maps.LatLng(40.5472,12.282715),
   zoom: 6,
   mapTypeId: google.maps.MapTypeId.ROADMAP
  };
  map = new google.maps.Map(document.getElementById("map-canvas"),
            mapOptions);
}
google.maps.event.addDomListener(window, 'load', initialize);
google.maps.event.addDomListener(window, "resize", function() {
 var center = map.getCenter();
 google.maps.event.trigger(map, "resize");
 map.setCenter(center); 
});

I love jQuery's method chaining. Simply do...

    var value = $("#text").val().replace('.',':');

    //Or if you want to return the value:
    return $("#text").val().replace('.',':');

this will unhide all files and folders on your computer

Escape with a double backslash

R treats backslashes as escape values for character constants. (... and so do regular expressions. Hence the need for two backslashes when supplying a character argument for a pattern. The first one isn't actually a character, but rather it makes the second one into a character.) You can see how they are processed using cat.

y <- "double quote: \", tab: \t, newline: \n, unicode point: \u20AC"
print(y)
## [1] "double quote: \", tab: \t, newline: \n, unicode point: €"
cat(y)
## double quote: ", tab:    , newline: 
## , unicode point: €

Further reading: Escaping a backslash with a backslash in R produces 2 backslashes in a string, not 1

To use special characters in a regular expression the simplest method is usually to escape them with a backslash, but as noted above, the backslash itself needs to be escaped.

grepl("\\[", "a[b")
## [1] TRUE

To match backslashes, you need to double escape, resulting in four backslashes.

grepl("\\\\", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

The rebus package contains constants for each of the special characters to save you mistyping slashes.

library(rebus)
OPEN_BRACKET
## [1] "\\["
BACKSLASH
## [1] "\\\\"

For more examples see:

?SpecialCharacters

Your problem can be solved this way:

library(rebus)
grepl(OPEN_BRACKET, "a[b")

Form a character class

You can also wrap the special characters in square brackets to form a character class.

grepl("[?]", "a?b")
## [1] TRUE

Two of the special characters have special meaning inside character classes: \ and ^.

Backslash still needs to be escaped even if it is inside a character class.

grepl("[\\\\]", c("a\\b", "a\nb"))
## [1]  TRUE FALSE

Caret only needs to be escaped if it is directly after the opening square bracket.

grepl("[ ^]", "a^b")  # matches spaces as well.
## [1] TRUE
grepl("[\\^]", "a^b") 
## [1] TRUE

rebus also lets you form a character class.

char_class("?")
## <regex> [?]

Use a pre-existing character class

If you want to match all punctuation, you can use the [:punct:] character class.

grepl("[[:punct:]]", c("//", "[", "(", "{", "?", "^", "$"))
## [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE

stringi maps this to the Unicode General Category for punctuation, so its behaviour is slightly different.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "[[:punct:]]")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

You can also use the cross-platform syntax for accessing a UGC.

stri_detect_regex(c("//", "[", "(", "{", "?", "^", "$"), "\\p{P}")
## [1]  TRUE  TRUE  TRUE  TRUE  TRUE FALSE FALSE

Use \Q \E escapes

Placing characters between \\Q and \\E makes the regular expression engine treat them literally rather than as regular expressions.

grepl("\\Q.\\E", "a.b")
## [1] TRUE

rebus lets you write literal blocks of regular expressions.

literal(".")
## <regex> \Q.\E

Don't use regular expressions

Regular expressions are not always the answer. If you want to match a fixed string then you can do, for example:

grepl("[", "a[b", fixed = TRUE)
stringr::str_detect("a[b", fixed("["))
stringi::stri_detect_fixed("a[b", "[")

You need to use the method equals() when comparing a string, otherwise you're just comparing the object references to each other, so in your case you want:

if (!statusCheck.equals("success")) {

When dealing with C++ strings (std::string), you're looking for length() or size(). Both should provide you with the same value. However when dealing with C-Style strings, you would use strlen().

#include <iostream>
#include <string.h>

int main(int argc, char **argv)
{
   std::string str = "Hello!";
   const char *otherstr = "Hello!"; // C-Style string
   std::cout << str.size() << std::endl;
   std::cout << str.length() << std::endl;
   std::cout << strlen(otherstr) << std::endl; // C way for string length
   std::cout << strlen(str.c_str()) << std::endl; // convert C++ string to C-string then call strlen
   return 0;
}

Output:

6
6

Call the global process object's exit method:

process.exit()

From the docs:

process.exit([exitcode])

Ends the process with the specified code. If omitted, exit uses the 'success' code 0.

To exit with a 'failure' code:

process.exit(1);

The shell that executed node should see the exit code as 1.

A tree in Python is quite simple. Make a class that has data and a list of children. Each child is an instance of the same class. This is a general n-nary tree.

class Node(object):
    def __init__(self, data):
        self.data = data
        self.children = []

    def add_child(self, obj):
        self.children.append(obj)

Then interact:

>>> n = Node(5)
>>> p = Node(6)
>>> q = Node(7)
>>> n.add_child(p)
>>> n.add_child(q)
>>> n.children
[<__main__.Node object at 0x02877FF0>, <__main__.Node object at 0x02877F90>]
>>> for c in n.children:
...   print c.data
... 
6
7
>>> 

This is a very basic skeleton, not abstracted or anything. The actual code will depend on your specific needs - I'm just trying to show that this is very simple in Python.

A third-party that is monitoring traffic may also be able to determine the page visited by examining your traffic an comparing it with the traffic another user has when visiting the site. For example if there were 2 pages only on a site, one much larger than the other, then comparison of the size of the data transfer would tell which page you visited. There are ways this could be hidden from the third-party but they're not normal server or browser behaviour. See for example this paper from SciRate, https://scirate.com/arxiv/1403.0297.

In general other answers are correct, practically though this paper shows that pages visited (ie URL) can be determined quite effectively.

Use INDIRECT()

=SUM(INDIRECT(<start cell here> & ":" & <end cell here>))

I have tried to run same program using eclipse and it shows clear difference between memcpy and memmove. memcpy() doesn't care about overlapping of memory location which results in corruption of data, while memmove() will copy data to temporary variable first and then copy into actual memory location.

While trying to copy data from location str1 to str1+2, output of memcpy is "aaaaaa". The question would be how? memcpy() will copy one byte at a time from left to right. As shown in your program "aabbcc" then all copying will take place as below,

1. aabbcc -> aaabcc

2. aaabcc -> aaaacc

3. aaaacc -> aaaaac

4. aaaaac -> aaaaaa

memmove() will copy data to temporary variable first and then copy to actual memory location.

1. aabbcc(actual) -> aabbcc(temp)

2. aabbcc(temp) -> aaabcc(act)

3. aabbcc(temp) -> aaaacc(act)

4. aabbcc(temp) -> aaaabc(act)

5. aabbcc(temp) -> aaaabb(act)

Output is

memcpy : aaaaaa

memmove : aaaabb

Here is a generic example of using a weak reference and static handler class to resolve the problem (as recommended in the Lint documentation):

public class MyClass{

  //static inner class doesn't hold an implicit reference to the outer class
  private static class MyHandler extends Handler {
    //Using a weak reference means you won't prevent garbage collection
    private final WeakReference<MyClass> myClassWeakReference; 

    public MyHandler(MyClass myClassInstance) {
      myClassWeakReference = new WeakReference<MyClass>(myClassInstance);
    }

    @Override
    public void handleMessage(Message msg) {
      MyClass myClass = myClassWeakReference.get();
      if (myClass != null) {
        ...do work here...
      }
    }
  }

  /**
   * An example getter to provide it to some external class
   * or just use 'new MyHandler(this)' if you are using it internally.
   * If you only use it internally you might even want it as final member:
   * private final MyHandler mHandler = new MyHandler(this);
   */
  public Handler getHandler() {
    return new MyHandler(this);
  }
}

You can get the Class reference of any class during run time through the Java Reflection Concept.

Check the Below Code. Explanation is given below

Here is one example that uses returned Class to create an instance of AClass:

package com.xyzws;
class AClass {
    public AClass() {
        System.out.println("AClass's Constructor"); 
    }  
    static {   
        System.out.println("static block in AClass");  
    }
}
public class Program {   
    public static void main(String[] args) {
        try {       
            System.out.println("The first time calls forName:");   
            Class c = Class.forName("com.xyzws.AClass");      
            AClass a = (AClass)c.newInstance();    
            System.out.println("The second time calls forName:");  
            Class c1 = Class.forName("com.xyzws.AClass"); 
        } catch (ClassNotFoundException e) { 
            // ...
        } catch (InstantiationException e) {  
            // ...
        } catch (IllegalAccessException e) { 
            // ...
        }     
    }
}

The printed output is

    The first time calls forName:
    static block in AClass
    AClass's Constructor
    The second time calls forName:

The class has already been loaded so there is no second "static block in AClass"

The Explanation is below

Class.ForName is called to get a Class Object

By Using the Class Object we are creating the new instance of the Class.

Any doubts about this let me know

Douglas Crockford discusses that topic extensively in The Good Parts. He recommends to avoid the new operator to create new objects. Instead he proposes to create customized constructors. For instance:

var mammal = function (spec) {     
   var that = {}; 
   that.get_name = function (  ) { 
      return spec.name; 
   }; 
   that.says = function (  ) { 
      return spec.saying || ''; 
   }; 
   return that; 
}; 

var myMammal = mammal({name: 'Herb'});

In Javascript a function is an object, and can be used to construct objects out of together with the new operator. By convention, functions intended to be used as constructors start with a capital letter. You often see things like:

function Person() {
   this.name = "John";
   return this;
}

var person = new Person();
alert("name: " + person.name);**

In case you forget to use the new operator while instantiating a new object, what you get is an ordinary function call, and this is bound to the global object instead to the new object.

There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1. This will always return True and "1" == 1 will always return False, since the types differ. Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types.

There's also the else clause:

# This will always print either "hi" or "no hi" unless something unforeseen happens.
if hi == "hi":     # The variable hi is being compared to the string "hi", strings are immutable in Python, so you could use the 'is' operator.
    print "hi"     # If indeed it is the string "hi" then print "hi"
else:              # hi and "hi" are not the same
    print "no hi"

The is operator is the object identity operator used to check if two objects in fact are the same:

a = [1, 2]
b = [1, 2]
print a == b # This will print True since they have the same values
print a is b # This will print False since they are different objects.

To add columns in existing table:

ALTER TABLE table_name
 ADD
 column_name DATATYPE NULL  

To delete columns in existing table:

ALTER TABLE table_name
DROP COLUMN column_name

I needed a variation on this, which I expect will be useful to others:

function diffs() {
        diff "${@:3}" <(sort "$1") <(sort "$2")
}

The "${@:3}" part means all the members of the array starting at 3. So this function implements a sorted diff by passing the first two arguments to diff through sort and then passing all other arguments to diff, so you can call it similarly to diff:

diffs file1 file2 [other diff args, e.g. -y]

You should use fgetcsv. Since you cannot import a file as a stream because the csv is a variable, then you should spoof the string as a file by using php://temp or php://memory first:

$fp = fopen("php://temp", 'r+');
fputs($fp, $csvText);
rewind($fp);

Then you will have no problem using fgetcsv:

$csv = [];
while ( ($data = fgetcsv($fp) ) !== FALSE ) {
    $csv[] = $data;
}

$data will be an array of a single csv line (which may include line breaks or commas, etc), as it should be.

Caveat: The memory limit of php://temp can be controlled by appending /maxmemory:NN, where NN is the maximum amount of data to keep in memory before using a temporary file, in bytes. (the default is 2 MB) http://www.php.net/manual/en/wrappers.php.php

I'm not able to comment first answer to your question, but there's a small mistake. You should use parseInt or Math.floor to convert floating point numbers to integer, i

var days, hours, minutes, seconds, x;
x = ms / 1000;
seconds = Math.floor(x % 60);
x /= 60;
minutes = Math.floor(x % 60);
x /= 60;
hours = Math.floor(x % 24);
x /= 24;
days = Math.floor(x);

Personally, I use CoffeeScript in my projects and my code looks like that:

getFormattedTime : (ms)->
        x = ms / 1000
        seconds = Math.floor x % 60
        x /= 60
        minutes = Math.floor x % 60
        x /= 60
        hours = Math.floor x % 24
        x /= 24
        days = Math.floor x
        formattedTime = "#{seconds}s"
        if minutes then formattedTime = "#{minutes}m " + formattedTime
        if hours then formattedTime = "#{hours}h " + formattedTime
        formattedTime 

you can use this query to do the above task

DECLARE @test NVARCHAR(max)
SELECT @test = COALESCE(@test + ',', '') + field2 FROM #test SELECT field2= @test

Same with something more complex...getting the ec2 instance region from within the instance.

INSTANCE_REGION=$(curl -s 'http://169.254.169.254/latest/dynamic/instance-identity/document' | python -c "import sys, json; print json.load(sys.stdin)['region']")

echo $INSTANCE_REGION

When there are multiple activities entries in AndroidManifest.xml, how does android know which activity to start first?

There is no "first". In your case, with your manifest as shown, you will have two icons in your launcher. Whichever one the user taps on is the one that gets launched.

I could not understand intent-filters. Can anyone please explain.

There is quite a bit of documentation on the subject. Please consider reading that, then asking more specific questions.

Also, when you get "application has stopped unexpectedly, try again", use adb logcat, DDMS, or the DDMS perspective in Eclipse to examine the Java stack trace associated with the error.

edit/update: Xcode 8.3.2 • Swift 3.1

If you know HTML and CSS you can use it to easily control the font style, color and size of your attributed string as follow:

extension String {
    var html2AttStr: NSAttributedString? {
        return try? NSAttributedString(data: Data(utf8), options: [NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType, NSCharacterEncodingDocumentAttribute: String.Encoding.utf8.rawValue], documentAttributes: nil)
    }
}

"<style type=\"text/css\">#red{color:#F00}#green{color:#0F0}#blue{color: #00F; font-weight: Bold; font-size: 32}</style><span id=\"red\" >Red,</span><span id=\"green\" > Green </span><span id=\"blue\">and Blue</span>".html2AttStr

Your code can simplified a lot to

$('img', resp).attr('src', function(idx, urlRelative ) {
    return self.config.proxy_server + self.config.location_images + urlRelative;
});

I encountered similar problems too. In my case it was solved by getting the cursor in this way:

cursor = self.conn.cursor(buffered=True)

For turning off line numbers, any of these commands will work:

1. :set nu!
2. :set nonu
3. :set number!
4. :set nonumber

When XML first came out, we were told it would solve all our problems: XML will be user-friendly, infinitely extensible, avoid strong-typing, and not require any programming skills. I learnt about DTD's and wrote my own XML parser. 15+ years later, I see that most XML is not user-friendly, and not very extensible (depending on its usage). As soon as some clever clogs hooked up XML to a database I knew that data types were all but inevitable. And, you should see the XSLT (transformation file) I had to work on the other day. If that isn't programming, I don't know what is! Nowadays it's not unusual to see all kinds of problems relating to XML data or interfaces gone bad. I love XML but, it has strayed far from its original altruistic starting point.

The short answer? DTD's have been deprecated in favor of XSD's because an XSD lets you define an XML structure with more precision.

var qty = 5;
var option = '';
for (var i=1;i <= qty;i++){
   option += '<option value="'+ i + '">' + i + '</option>';
}
$('#items').append(option);

If you have python installed completely, it can save you the hassle. All you need to do is enter the following command in your respective shell:

pip install pyqt5

And contrary to popular belief, AS LONG AS YOU HAVE PIP INSTALLED, you can do this on virtually any OS... Hope this helped!

GPS is generally more accurate than network but sometimes GPS is not available, therefore you might need to switch between the two.

A good start might be to look at the android dev site. They had a section dedicated to determining user location and it has all the code samples you need.

http://developer.android.com/guide/topics/location/obtaining-user-location.html

If you're inside an iframe that don't have cross domain src, or src is empty:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Check if window.frameElement not null
    if(window.frameElement) {
        href = window.frameElement.ownerDocument.location.href;
        // This one will be origin
        if(window.frameElement.ownerDocument.referrer != "") {
            referrer = window.frameElement.ownerDocument.referrer;
        }
    }
    // Compare if href not equal to referrer
    if(href != referrer) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href
    }
}

If you're inside an iframe with cross domain src:

Then:

function getOriginUrl() {
    var href = document.location.href;
    var referrer = document.referrer;
    // Detect if you're inside an iframe
    if(window.parent != window) {
        // Take referrer as origin
        return referrer;
    } else {
        // Take href
        return href;
    }
}

See this table.

A 101x101 QR code, with high level error correction, can hold 3248 bits, or 406 bytes. Probably not enough for any meaningful SVG/XML data.

A 177x177 grid, depending on desired level of error correction, can store between 1273 and 2953 bytes. Maybe enough to store something small.

Please don't use MD5 for password hashing. Such passwords can be cracked in milliseconds. You're sure to be pwned by cybercriminals.

PHP offers a high-quality and future proof password hashing subsystem based on a reliable random salt and multiple rounds of Rijndael / AES encryption.

When a user first provides a password you can hash it like this:

 $pass = 'whatever the user typed in';
 $hashed_password = password_hash( "secret pass phrase", PASSWORD_DEFAULT );

Then, store $hashed_password in a varchar(255) column in MySQL. Later, when the user wants to log in, you can retrieve the hashed password from MySQL and compare it to the password the user offered to log in.

 $pass = 'whatever the user typed in';
 $hashed_password = 'what you retrieved from MySQL for this user';
 if ( password_verify ( $pass , $hashed_password )) {
    /* future proof the password */
    if ( password_needs_rehash($hashed_password , PASSWORD_DEFAULT)) {
       /* recreate the hash */
       $rehashed_password = password_hash($pass, PASSWORD_DEFAULT );
       /* store the rehashed password in MySQL */
     }
     /* password verified, let the user in */
 }
 else {
     /* password not verified, tell the intruder to get lost */
 }

How does this future-proofing work? Future releases of PHP will adapt to match faster and easier to crack encryption. If it's necessary to rehash passwords to make them harder to crack, the future implementation of the password_needs_rehash() function will detect that.

Don't reinvent the flat tire. Use professionally designed and vetted open source code for security.

This might be simplest way -

Collections.sort(listOfStudent,new Comparator<Student>(){
                     public int compare(Student s1,Student s2){
                           // Write your logic here.
                     }});

Using Java 8(lambda expression) -

listOfStudent.sort((s1, s2) -> s1.age - s2.age); 

The accepted answer is not the right one, because the question is not about renaming a file into a file, but moving many files into a directory. shutil.move will do the work, but for this purpose os.rename is useless (as stated on comments) because destination must have an explicit file name.

There is always this of course:

(async () => {
    await ...

    // all of the script.... 

})();
// nothing else

This makes a quick function with async where you can use await. It saves you the need to make an async function which is great! //credits Silve2611

First you need an object

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

Because you are using ARC you must be using iOS 4.0 or later. This means you could use blocks. If instead of remembering the selector to perform you instead took a block, ARC would be able to better track what is actually going on and you wouldn't have to run the risk of accidentally introducing a memory leak.

You can use rabbitmqctl eval as below:

rabbitmqctl eval 'IfUnused = false, IfEmpty = true, MatchRegex = 
<<"^prefix-">>, [rabbit_amqqueue:delete(Q, IfUnused, IfEmpty) || Q <- 
rabbit_amqqueue:list(), re:run(element(4, element(2, Q)), MatchRegex) 
=/= nomatch ].' 

The above will delete all empty queues in all vhosts that have a name beginning with "prefix-". You can edit the variables IfUnused, IfEmpty, and MatchRegex as per your requirement.

What you want is a SQL case statement. The form of these is either:

  select case [expression or column]
  when [value] then [result]
  when [value2] then [result2]
  else [value3] end

or:

  select case 
  when [expression or column] = [value] then [result]
  when [expression or column] = [value2] then [result2]
  else [value3] end

In your example you are after:

declare @temp as varchar(100)
set @temp='Measure'

select case @temp 
   when 'Measure' then Measure 
   else OtherMeasure end
from Measuretable

The following should do the trick:

div[class^='myclass'], div[class*=' myclass']{
    color: #F00;
}

Edit: Added wildcard (*) as suggested by David

You need to add android:exported="true" to start service from ADB command line. Then your manifest looks something like this:

<!-- Service declared in manifest -->
<service
    android:name=".YourServiceName"
    android:exported="true"
    android:launchMode="singleTop">
    <intent-filter>
        <action android:name="com.your.package.name.YourServiceName"/>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</service> <!-- Note: Service is exported to start it using ADB command -->

And then from ADB

To start service:

adb shell am startservice com.your.package.name/.YourServiceName

To stop service (on Marshmallow):

adb shell am stopservice com.your.package.name/.YourServiceName

To stop service (on Jelly Bean):

adb shell am force-stop com.your.package.name

data = File.read("/path/to/file")

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

ok, here is what i understood from your question. You are writing a csv file from python but when you are opening that file into some other application like excel or open office they are showing the complete row in one cell rather than each word in individual cell. I am right??

if i am then please try this,

import csv

with open(r"C:\\test.csv", "wb") as csv_file:
    writer = csv.writer(csv_file, delimiter =",",quoting=csv.QUOTE_MINIMAL)
    writer.writerow(["a","b"])

you have to set the delimiter = ","

 1,new Long(intValue);
 2,Long.valueOf(intValue);

for frequency distribution of a variable with excessive values you can collapse down the values in classes,

Here I excessive values for employrate variable, and there's no meaning of it's frequency distribution with direct values_count(normalize=True)

                country  employrate alcconsumption
0           Afghanistan   55.700001            .03

212            Zimbabwe   66.800003           4.96

[213 rows x 3 columns]

frequency distribution with values_count(normalize=True) with no classification,length of result here is 139 (seems meaningless as a frequency distribution):

print(gm["employrate"].value_counts(sort=False,normalize=True))

50.500000   0.005618
61.500000   0.016854

65.599998   0.005618
68.300003   0.005618
Name: employrate, Length: 139, dtype: float64

putting classification we put all values with a certain range ie.

0-10 as 1,
11-20 as 2  
21-30 as 3, and so forth.

gm["employrate"]=gm["employrate"].str.strip().dropna()  
gm["employrate"]=pd.to_numeric(gm["employrate"])
gm['employrate'] = np.where(
   (gm['employrate'] <=10) & (gm['employrate'] > 0) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=20) & (gm['employrate'] > 10) , 1, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=30) & (gm['employrate'] > 20) , 2, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=40) & (gm['employrate'] > 30) , 3, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=50) & (gm['employrate'] > 40) , 4, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=60) & (gm['employrate'] > 50) , 5, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=70) & (gm['employrate'] > 60) , 6, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=80) & (gm['employrate'] > 70) , 7, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=90) & (gm['employrate'] > 80) , 8, gm['employrate']
   )
gm['employrate'] = np.where(
   (gm['employrate'] <=100) & (gm['employrate'] > 90) , 9, gm['employrate']
   )
print(gm["employrate"].value_counts(sort=False,normalize=True))

after classification we have a clear frequency distribution. here we can easily see, that 37.64% of countries have employ rate between 51-60% and 11.79% of countries have employ rate between 71-80%

5.000000   0.376404

1. Create your shell script as login.sh in your $HOME folder.

2. Paste the following one-line script into Script Editor:

   do shell script "$HOME/login.sh"

3. Then save it as an application.

4. Finally add the application to your login items.

If you want to make the script output visual, you can swap step 2 for this:

tell application "Terminal"
  activate
  do script "$HOME/login.sh"
end tell

If multiple commands are needed something like this can be used:

tell application "Terminal"
  activate
  do script "cd $HOME"
  do script "./login.sh" in window 1
end tell

MySQL allows a more readable way to combine multiple updates into a single query. This seems to better fit the scenario you describe, is much easier to read, and avoids those difficult-to-untangle multiple conditions.

INSERT INTO table_users (cod_user, date, user_rol, cod_office)
VALUES
('622057', '12082014', 'student', '17389551'),
('2913659', '12082014', 'assistant','17389551'),
('6160230', '12082014', 'admin', '17389551')
ON DUPLICATE KEY UPDATE
 cod_user=VALUES(cod_user), date=VALUES(date)

This assumes that the user_rol, cod_office combination is a primary key. If only one of these is the primary key, then add the other field to the UPDATE list. If neither of them is a primary key (that seems unlikely) then this approach will always create new records - probably not what is wanted.

However, this approach makes prepared statements easier to build and more concise.

Try this:

return preg_replace("/[^0-9]/", "",$c);

You almost got it. It should be this:

<label for="r1"> button one</label>

The value in for should be the id of the element you are labeling.

From your command line, you can do this:

I don't think it's in the INFORMATION_SCHEMA - you'll probably have to use sysobjects or related deprecated tables/views.

You would think there would be a type for this in INFORMATION_SCHEMA.TABLE_CONSTRAINTS, but I don't see one.

Tons of great suggestions here, just going to throw ZingChart onto the stack for good measure. We recently released a jQuery wrapper for the library that makes it even easier to build and customize charts. The CDN links are in the demo below.

You probably mean Notification.Builder.setLargeIcon(Bitmap), right? :)

You're misunderstanding the meaning of the merge here.

The --no-commit prevents the MERGE COMMIT from occuring, and that only happens when you merge two divergent branch histories; in your example that's not the case since Git indicates that it was a "fast-forward" merge and then Git only applies the commits already present on the branch sequentially.

If you're using Cordova 3.3 or higher and your device is running Android 4.4 or higher you can use 'Remote Debugging on Android with Chrome'. Full instructions are here:

https://developer.chrome.com/devtools/docs/remote-debugging

In summary:

• Plug the device into your desktop computer using a USB cable
• Enable USB debugging on your device (on my device this is under Settings > More > Developer options > USB debugging)

Or, if you're using Cordova 3.3+ and don't have a physical device with 4.4, you can use an emulator that uses Android 4.4+ to run the application through the emulator, on your desktop computer.

• Run your Cordova application on the device or emulator
• In Chrome on your desktop computer, enter chrome://inspect/#devices in the address bar
• Your device/emulator will be displayed along with any other recognised devices that are connected to your computer, and under your device there will be details of the Cordova 'WebView' (basically your Cordova app), which is running on the device/emulator (the way Cordova works is that it basically creates a 'browser' window on your device/emulator, within which there is a 'WebView' which is your running HTML/JavaScript app)
• Click the 'inspect' link under the 'WebView' section where you see your device/emulator listed. This brings up the Chrome developer tools that now allow you to debug your application.
• Select the 'sources' tab of the Chrome developer tools to view JavaScript that your Cordova app on the device/emulator is currently running. You can add breakpoints in the JavaScript that allow you to debug your code.
• Also, you can use the 'console' tab to view any errors (which will be shown in red), or at the bottom of the console you'll see a '>' prompt. Here you can type in any variables or objects (e.g. DOM objects) that you want to inspect the current value of, and the value will be displayed.

If You have got this error while running composer install command, don't worry. Steps to be followed and requirements:

• Step1: Go to server folder such as xampp(or) wampp etc.
  
• Step2: open php folder inside that and go to ext folder.
  
• Step3: If you find a file named as php_intl.dll no problem.

Just go to php.ini file and uncomment the line

From:

;extension=php_intl.dll

To:

extension=php_intl.dll

• Step4: restart xampp, thats it

Note: If you don't find any of the file named as php_intl.dll, then you need to upgrade the PHP version.

With localStorage, web applications can store data locally within the user's browser. Before HTML5, application data had to be stored in cookies, included in every server request. Large amounts of data can be stored locally, without affecting website performance. Although localStorage is more modern, there are some pros and cons to both techniques.

Cookies

Pros

• Legacy support (it's been around forever)
• Persistent data
• Expiration dates

Cons

• Each domain stores all its cookies in a single string, which can make parsing data difficult
• Data is unencrypted, which becomes an issue because... ... though small in size, cookies are sent with every HTTP request Limited size (4KB)
• SQL injection can be performed from a cookie

Local storage

Pros

• Support by most modern browsers
• Persistent data that is stored directly in the browser
• Same-origin rules apply to local storage data
• Is not sent with every HTTP request
• ~5MB storage per domain (that's 5120KB)

Cons

• Not supported by anything before: IE 8, Firefox 3.5, Safari 4, Chrome 4, Opera 10.5, iOS 2.0, Android 2.0
• If the server needs stored client information you purposely have to send it.

localStorage usage is almost identical with the session one. They have pretty much exact methods, so switching from session to localStorage is really child's play. However, if stored data is really crucial for your application, you will probably use cookies as a backup in case localStorage is not available. If you want to check browser support for localStorage, all you have to do is run this simple script:

/* 
* function body that test if storage is available
* returns true if localStorage is available and false if it's not
*/
function lsTest(){
    var test = 'test';
    try {
        localStorage.setItem(test, test);
        localStorage.removeItem(test);
        return true;
    } catch(e) {
        return false;
    }
}

/* 
* execute Test and run our custom script 
*/
if(lsTest()) {
    // window.sessionStorage.setItem(name, 1); // session and storage methods are very similar
    window.localStorage.setItem(name, 1);
    console.log('localStorage where used'); // log
} else {
    document.cookie="name=1; expires=Mon, 28 Mar 2016 12:00:00 UTC";
    console.log('Cookie where used'); // log
}

"localStorage values on Secure (SSL) pages are isolated" as someone noticed keep in mind that localStorage will not be available if you switch from 'http' to 'https' secured protocol, where the cookie will still be accesible. This is kind of important to be aware of if you work with secure protocols.

You can also use the code below, if you do not want to get IndexError when the list is empty.

next(reversed(some_list), None)

This works in Linux & Windows:

Python 3.x

>>> import sys
>>> print(sys.executable)
C:\path\to\python.exe

Python 2.x

>>> import sys
>>> print sys.executable
/usr/bin/python

There is no installation required. Just add jQuery to your application folder and give a reference to the js file.

<script type="text/javascript" src="jQuery.js"></script>

if jQuery is in the same folder of your referenced file.

It isn't possible as DateTime is immutable. The same discussion is available here: How to change time in datetime?

The easiest way of doing this is using pdfHTML. It's an iText7 add-on that converts HTML5 (+CSS3) into pdf syntax.

The code is pretty straightforward:

    HtmlConverter.convertToPdf(
        "<b>This text should be written in bold.</b>",       // html to be converted
        new PdfWriter(
            new File("C://users/mark/documents/output.pdf")  // destination file
        )
    );

I did a pure javascript hack to make this possible.

<div class="my_background_image" style="background-image: url(broken-image.jpg)">
<img class="image_error" src="broken-image.jpg" onerror="this.parentElement.style.display='none';">
</div>

Or

onerror="this.parentElement.backgroundImage = "url('image_placeHolder.png')";

css:

.image_error {
    display: none;
}

require 5.013002; # or better:    use Syntax::Construct qw(/r);
print "bla: ", $myvar =~ s/a/b/r, "\n";

See perl5132delta:

The substitution operator now supports a /r option that copies the input variable, carries out the substitution on the copy and returns the result. The original remains unmodified.

my $old = 'cat';
my $new = $old =~ s/cat/dog/r;
# $old is 'cat' and $new is 'dog'

Simple way that works and I checked.

private readonly UserManager<IdentityUser> _userManager;
public CompetitionsController(UserManager<IdentityUser> userManager)
{
    _userManager = userManager;
}

var user = await _userManager.GetUserAsync(HttpContext.User);

then you can all the properties of this variables like user.Email. I hope this would help someone.

Edit:

It's an apparently simple thing but bit complicated cause of different types of authentication systems in ASP.NET Core. I update cause some people are getting null.

For JWT Authentication (Tested on ASP.NET Core v3.0.0-preview7):

var email = HttpContext.User.Claims.FirstOrDefault(c => c.Type == "sub")?.Value;

var user = await _userManager.FindByEmailAsync(email);

You could use:

echo date('F Y', strtotime('20130814'));

which should do the trick.

Edit: You have a date which is in a string format. To be able to format it nicelt, you first need to change it into a date itself - which is where strtotime comes in. It is a fantastic feature that converts almost any plausible expression of a date into a date itself. Then we can actually use the date() function to format the output into what you want.

Before Java 8 (versions 7 or 6) I use the new method ArgumentMatchers.anyList:

import static org.mockito.Mockito.*;
import org.mockito.ArgumentMatchers;

verify(mock, atLeastOnce()).process(ArgumentMatchers.<Bar>anyList());

Based on Ahmed's answer, after some cleaning up and generalization, including the other "Find" parameters, so we can use this function in any situation:

'Uses Range.Find to get a range of all find results within a worksheet
' Same as Find All from search dialog box
'
Function FindAll(rng As Range, What As Variant, Optional LookIn As XlFindLookIn = xlValues, Optional LookAt As XlLookAt = xlWhole, Optional SearchOrder As XlSearchOrder = xlByColumns, Optional SearchDirection As XlSearchDirection = xlNext, Optional MatchCase As Boolean = False, Optional MatchByte As Boolean = False, Optional SearchFormat As Boolean = False) As Range
    Dim SearchResult As Range
    Dim firstMatch As String
    With rng
        Set SearchResult = .Find(What, , LookIn, LookAt, SearchOrder, SearchDirection, MatchCase, MatchByte, SearchFormat)
        If Not SearchResult Is Nothing Then
            firstMatch = SearchResult.Address
            Do
                If FindAll Is Nothing Then
                    Set FindAll = SearchResult
                Else
                    Set FindAll = Union(FindAll, SearchResult)
                End If
                Set SearchResult = .FindNext(SearchResult)
            Loop While Not SearchResult Is Nothing And SearchResult.Address <> firstMatch
        End If
    End With
End Function

the easiest way to clone an array is

backUpData = genericItems.concat();

This will create a new memory for the array indexes

I think the above answer posted by Jeremy Thompson is the correct one, but I don't have enough street cred to comment. Once I updated nuget and powershellget, Install-Module was available for me.

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force 
Install-PackageProvider -Name Powershellget -Force

What is interesting is that the version numbers returned by get-packageprovider didn't change after the update.

<?php
    $j=1; 


      array_reverse($skills_nav);   


    foreach ( $skills_nav as $skill ) {
        $a = '<li><a href="#" data-filter=".'.$skill->slug.'">';
        $a .= $skill->name;                 
        $a .= '</a></li>';
        echo $a;
        echo "\n";
        $j++;
    }
?> 

This is an alternative solution without any char conversions:

DATEADD(ms, DATEDIFF(ms, '00:00:00', [Time]), CONVERT(DATETIME, [Date]))

You will only get milliseconds accuracy this way, but that would normally be OK. I have tested this in SQL Server 2008.

I forgot to tell a bug when i use I use req.session.email = req.param('email'), the server error says cannot sett property email of undefined.

The reason of this error is a wrong order of app.use. You must configure express in this order:

app.use(express.cookieParser());
app.use(express.session({ secret: sessionVal }));
app.use(app.route);

There are many good answers on this page.

1. I typically start with maximize.window(), actually I do this in the driver Factory or wherever you initialize your driver. This is something done by default - always.
2. Its usually a wait for element because of some javascript delay.

Both are discussed in various details above. The answer I didn't see was ScrollToElement. It sounds like you are processing a list of elements, while processing you are creating more elements, checkboxes. This can cause elements in your list to move off the visible page. Sometimes you can see the element with the naked eye but you just can't click on it. When processing lists you sometimes have to interject scrolling.

• Set a break point and check to see if the element you are using is at the window edge, top/bottom right/left. Sometimes when this is the case you can't get to it via selenium but you can manually click with your mouse.

Because I run across this I created a PageScroll.java and put my scrolling scripts there. Here are a few of the methods from this class:

public static void scrollToTop(WebDriver driver) {
      ((JavascriptExecutor) driver)
        .executeScript("window.scrollTo(0,0)");
    }

    public static void scrollToBottom(WebDriver driver) {
      ((JavascriptExecutor) driver)
        .executeScript("window.scrollTo(0, document.body.scrollHeight)");
    }

    public static void scrollToElementTop(WebDriver driver, WebElement element) {
      ((JavascriptExecutor) driver).executeScript(
        "arguments[0].scrollIntoView(true);", element);
    }

    public static void scrollToElementBottom(WebDriver driver, WebElement element) {
      ((JavascriptExecutor) driver).executeScript(
        "arguments[0].scrollIntoView(false);", element);
    }

see Scroll Element into View with Selenium for more examples

Use the children funcion of jQuery.

$("#text-field").keydown(function(event) {
    if($('#popup').children('p.filled-text').length > 0) {
        console.log("Found");
     }
});

$.children('').length will return the count of child elements which match the selector.

Not php.ini file, but a way around it. Go to GoDaddy's

Choose your file and click Upload. No timeouts. Rename the DB if needed, and assign a user in

Like this:

InputStream stream = new ByteArrayInputStream(exampleString.getBytes(StandardCharsets.UTF_8));

Note that this assumes that you want an InputStream that is a stream of bytes that represent your original string encoded as UTF-8.

For versions of Java less than 7, replace StandardCharsets.UTF_8 with "UTF-8".

The accepted answer was fundamentally flawed, it has since been deleted. The correct answer is:

function scrolled(e) {
  if (myDiv.offsetHeight + myDiv.scrollTop >= myDiv.scrollHeight) {
    scrolledToBottom(e);
  }
}

Tested this in Firefox, Chrome and Opera. It works.

It is sure because the Invoke-WebRequest command has a dependency on the Internet Explorer assemblies and are invoking it to parse the result as per default behaviour. As Matt suggest, you can simply launch IE and make your selection in the settings prompt which is popping up at first launch. And the error you experience will disappear.

But this is only possible if you run your powershell scripts as the same windows user as whom you launched the IE with. The IE settings are stored under your current windows profile. So if you, like me run your task in a scheduler on a server as the SYSTEM user, this will not work.

So here you will have to change your scripts and add the -UseBasicParsing argument, as ijn this example: $WebResponse = Invoke-WebRequest -Uri $url -TimeoutSec 1800 -ErrorAction:Stop -Method:Post -Headers $headers -UseBasicParsing

Suppose you bound your combobox to a List<Person>

List<Person> pp = new List<Person>();
pp.Add(new Person() {id = 1, name="Steve"});
pp.Add(new Person() {id = 2, name="Mark"});
pp.Add(new Person() {id = 3, name="Charles"});

cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;

At this point you cannot set the Text property as you like, but instead you need to add an item to your list before setting the datasource

pp.Insert(0, new Person() {id=-1, name="--SELECT--"});
cbo1.DisplayMember = "name";
cbo1.ValueMember = "id";
cbo1.DataSource = pp;
cbo1.SelectedIndex = 0;

Of course this means that you need to add a checking code when you try to use the info from the combobox

if(cbo1.SelectedValue != null && Convert.ToInt32(cbo1.SelectedValue) == -1)
    MessageBox.Show("Please select a person name");
else
    ...... 

The code is the same if you use a DataTable instead of a list. You need to add a fake row at the first position of the Rows collection of the datatable and set the initial index of the combobox to make things clear. The only thing you need to look at are the name of the datatable columns and which columns should contain a non null value before adding the row to the collection

In a table with three columns like ID, FirstName, LastName with ID,FirstName and LastName required you need to

DataRow row = datatable.NewRow();
row["ID"] = -1;
row["FirstName"] = "--Select--";    
row["LastName"] = "FakeAddress";
dataTable.Rows.InsertAt(row, 0);

In this case, you can do ajax call inside componentDidMount, and then update state

export default class UserList extends React.Component {
  constructor(props) {
    super(props);

    this.state = {person: []};
  }

  componentDidMount() {
    this.UserList();
  }

  UserList() {
    $.getJSON('https://randomuser.me/api/')
      .then(({ results }) => this.setState({ person: results }));
  }

  render() {
    const persons = this.state.person.map((item, i) => (
      <div>
        <h1>{ item.name.first }</h1>
        <span>{ item.cell }, { item.email }</span>
      </div>
    ));

    return (
      <div id="layout-content" className="layout-content-wrapper">
        <div className="panel-list">{ persons }</div>
      </div>
    );
  }
}

Usage:

sftp("file:/C:/home/file.txt", "ssh://user:pass@host/home");
sftp("ssh://user:pass@host/home/file.txt", "file:/C:/home");

Implementation

In my case, VS 2019 on Windows 10 x64, I followed mostly what it was said in the answers but pasted rc.exe and rcdll.dll from C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x86 to C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin, which is where link.exe is.

Just for completeness, there is also the LINQ/Lambda way:

myMoney.ForEach((theMoney) => Console.WriteLine("amount is {0}, and type is {1}", theMoney.amount, theMoney.type));

You can use this site: https://cachedviews.com/ . Cache View or Cached Pages of Any Website - Google Cached Pages of Any Website

My best approach is:

var item = {...}
var items = [{id:2}, {id:2}, {id:2}];

items[items.findIndex(el => el.id === item.id)] = item;

Reference for findIndex

And in case you don't want to replace with new object, but instead to copy the fields of item, you can use Object.assign:

Object.assign(items[items.findIndex(el => el.id === item.id)], item)

as an alternative with .map():

Object.assign(items, items.map(el => el.id === item.id? item : el))

Functional approach:

Don't modify the array, use a new one, so you don't generate side effects

const updatedItems = items.map(el => el.id === item.id ? item : el)

The solution to close a window in wpf that that worked for me is not answered here so i thought i would add my solution too.

        private static Window GetWindow(DependencyObject sender)
        {
            Window window = null;
            if (sender is Window)
                window = (Window)sender;
            if (window == null)
                window = Window.GetWindow(sender);
            return window;
        }
        private void CloseWindow(object sender, RoutedEventArgs e)
        {
            var button = (Button)sender as DependencyObject;

            Window window = GetWindow(button);
                if (window != null)
                    window.Close();
                   // window.Visibility = Visibility.Hidden; 
           // choose between window.close or set window.visibility to close or hide the window.

            //            }
        }

Add CloseWindow event to the button in you window as following.

<Button Content="Cancel" Click="CloseWindow" >

You also can use this:

var firstOrDefault = lstComp.FirstOrDefault();
if(firstOrDefault != null) 
{
    //doSmth
}

This was so annoying. Open your project, click on Target, Open Build Phases tab. Check your Copy Bundle Resources for any red items.

Just use format(number, qtyDecimals) sample: format(1000, 2) result 1000.00

This two commands work for me in my project

composer require laravel/ui --dev

Then

php artisan ui:auth

Since I was helped with my project by the answer above (I asked a duplicate question and was referred here), I am submitting an answer (my test code) for bracket notation when nesting within the var:

Here is the code by AbacusUtil

Map<Integer, String> map = N.asMap(1, "one", 2, "two");
// Or for Immutable map 
ImmutableMap<Integer, String> = ImmutableMap.of(1, "one", 2, "two");

Adding up on EJP's answer; use this for more fluidity. Make sure you don't put his code inside a bigger try catch with more code between the .read and the catch block, it may return an exception and jump all the way to the outer catch block, safest bet is to place EJPS's while loop inside a try catch, and then continue the code after it, like:

int count;
byte[] bytes = new byte[4096];
try {
    while ((count = is.read(bytes)) > 0) {
        System.out.println(count);
        bos.write(bytes, 0, count);
    }
} catch ( Exception e )
{
    //It will land here....
}
// Then continue from here

EDIT: ^This happened to me cuz I didn't realize you need to put socket.shutDownOutput() if it's a client-to-server stream!

Hope this post solves any of your issues

I'll elaborate a bit more on ChrisR awesome answer and bring images from his awesome reference.

A valid JSON always starts with either curly braces { or square brackets [, nothing else.

{ will start an object:

{ "key": value, "another key": value }

Hint: although javascript accepts single quotes ', JSON only takes double ones ".

[ will start an array:

[value, value]

Hint: spaces among elements are always ignored by any JSON parser.

And value is an object, array, string, number, bool or null:

So yeah, ["a", "b"] is a perfectly valid JSON, like you could try on the link Manish pointed.

Here are a few extra valid JSON examples, one per block:

{}

[0]

{"__comment": "json doesn't accept comments and you should not be commenting even in this way", "avoid!": "also, never add more than one key per line, like this"}

[{   "why":null} ]

{
  "not true": [0, false],
  "true": true,
  "not null": [0, 1, false, true, {
    "obj": null
  }, "a string"]
}

This category may be to your taste. But! Be frugal with its usage; since we are converting to a NSMutableArray and back again, it's not at all efficient.

@implementation NSArray (mxcl)

- (NSArray *)arrayByRemovingObject:(id)obj
{
    if (!obj) return [self copy]; // copy because all array* methods return new arrays
    NSMutableArray *mutableArray = [NSMutableArray arrayWithArray:self];
    [mutableArray removeObject:obj];
    return [NSArray arrayWithArray:mutableArray];
}

@end

I've written a library to handle this for me. It's called DataTableProxy and is available as a NuGet package. Code and documentation is on Github

Use the id of the element to do the same.

document.getElementById(id).style.visibility = 'hidden';

I did it this way,

<audio controls="controls" loop="loop">
<source src="someSound.ogg" type="audio/ogg" />
</audio>

and it looks like this

Nope... just use a DL:

dl { overflow:hidden; }
dt {
 float:left;
 clear: left;
 width:4em; /* adjust the width; make sure the total of both is 100% */
 text-align: right
}
dd {
 float:left;
 width:50%; /* adjust the width; make sure the total of both is 100% */
 margin: 0 0.5em;
}

The following seems to work:

ul#menu li a {
    color:#696969;
    display:block;
    font-weight:bold;
    line-height:2.8;
    text-decoration:none;
    width:100%;
}

I don't see this possibility among answers, probably because the question is from 2008, but in 2018 you can use Matt Goldbolt's online website https://godbolt.org

You can also locally git clone and run his project https://github.com/mattgodbolt/compiler-explorer

I looked into what you are trying to achieve, because I remember I wanted to do the same thing. Inspired by Vinay I wrote something that works for me and I sort of understand. But I am not an expert, so please be careful.

I don't know how Vinay knows you are using Mac OS X. But it should work kind of like this with most unix-like OS. Really helpful as resource is opengroup.org

Make sure to flush the buffer before using the function.

#include <stdio.h>
#include <termios.h>        //termios, TCSANOW, ECHO, ICANON
#include <unistd.h>     //STDIN_FILENO


void pressKey()
{
    //the struct termios stores all kinds of flags which can manipulate the I/O Interface
    //I have an old one to save the old settings and a new 
    static struct termios oldt, newt;
    printf("Press key to continue....\n");

    //tcgetattr gets the parameters of the current terminal
    //STDIN_FILENO will tell tcgetattr that it should write the settings
    // of stdin to oldt
    tcgetattr( STDIN_FILENO, &oldt);
    //now the settings will be copied 
    newt = oldt;

    //two of the c_lflag will be turned off
    //ECHO which is responsible for displaying the input of the user in the terminal
    //ICANON is the essential one! Normally this takes care that one line at a time will be processed
    //that means it will return if it sees a "\n" or an EOF or an EOL
    newt.c_lflag &= ~(ICANON | ECHO );      

    //Those new settings will be set to STDIN
    //TCSANOW tells tcsetattr to change attributes immediately. 
    tcsetattr( STDIN_FILENO, TCSANOW, &newt);

    //now the char wil be requested
    getchar();

    //the old settings will be written back to STDIN
    tcsetattr( STDIN_FILENO, TCSANOW, &oldt);

}


int main(void)
{
  pressKey();
  printf("END\n");
  return 0;
}

O_NONBLOCK seems also to be an important flag, but it didn't change anything for me.

I appreciate if people with some deeper knowledge would comment on this and give some advice.

To those who use centos and have stumbled upon this post :

 $ yum install curl-devel

and when compiling your program example.cpp, link to the curl library:

 $ g++ example.cpp -lcurl -o example

"-o example" creates the executable example instead of the default a.out.

The next line runs example:

 $ ./example

I like your solution and implemented it on my site - however, with some little improvements. Just wanted to share my code:

function detectSwipe(id, f) {
    var detect = {
        startX: 0,
        startY: 0,
        endX: 0,
        endY: 0,
        minX: 30,   // min X swipe for horizontal swipe
        maxX: 30,   // max X difference for vertical swipe
        minY: 50,   // min Y swipe for vertial swipe
        maxY: 60    // max Y difference for horizontal swipe
    },
        direction = null,
        element = document.getElementById(id);

    element.addEventListener('touchstart', function (event) {
        var touch = event.touches[0];
        detect.startX = touch.screenX;
        detect.startY = touch.screenY;
    });

    element.addEventListener('touchmove', function (event) {
        event.preventDefault();
        var touch = event.touches[0];
        detect.endX = touch.screenX;
        detect.endY = touch.screenY;
    });

    element.addEventListener('touchend', function (event) {
        if (
            // Horizontal move.
            (Math.abs(detect.endX - detect.startX) > detect.minX)
                && (Math.abs(detect.endY - detect.startY) < detect.maxY)
        ) {
            direction = (detect.endX > detect.startX) ? 'right' : 'left';
        } else if (
            // Vertical move.
            (Math.abs(detect.endY - detect.startY) > detect.minY)
                && (Math.abs(detect.endX - detect.startX) < detect.maxX)
        ) {
            direction = (detect.endY > detect.startY) ? 'down' : 'up';
        }

        if ((direction !== null) && (typeof f === 'function')) {
            f(element, direction);
        }
    });
}

Use it like:

detectSwipe('an_element_id', myfunction);

Or

detectSwipe('another_element_id', my_other_function);

If a swipe is detected the function myfunction is called with parameter element-id and 'left', 'right', 'up' oder 'down'.

From Django docs:

The include tag should be considered as an implementation of "render this subtemplate and include the HTML", not as "parse this subtemplate and include its contents as if it were part of the parent". This means that there is no shared state between included templates -- each include is a completely independent rendering process.

So Django doesn't grab any blocks from your commondata.html and it doesn't know what to do with rendered html outside blocks.

See the following example which illustrate everything about try-except-else-finally:

for i in range(3):
    try:
        y = 1 / i
    except ZeroDivisionError:
        print(f"\ti = {i}")
        print("\tError report: ZeroDivisionError")
    else:
        print(f"\ti = {i}")
        print(f"\tNo error report and y equals {y}")
    finally:
        print("Try block is run.")

Implement it and come by:

    i = 0
    Error report: ZeroDivisionError
Try block is run.
    i = 1
    No error report and y equals 1.0
Try block is run.
    i = 2
    No error report and y equals 0.5
Try block is run.

    var user = {'name':'John'};
    sessionStorage['user'] = JSON.stringify(user);
    console.log(sessionStorage['user']);

For windows users ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

I had the same issue, and this trick works for me

1. Goto control panel
2. Open Uninstall program
3. Click on turn windows features on or off
4. Scroll down and find the hyper-V folder.
5. Uncheck the Hyper-V.
6. Apply changes and restart your system.
7. Now here you go... Open your virtual box and start the os you want.

Hope this helps..

Inline styling would work in any case

  <p-column field="Quantity" header="Qté" [style]="{'width':'48px'}">

If you can't use rgba due to browser support, and you don't want to include a semi-transparent white PNG, you will have to create two positioned elements. One for the white box, with opacity, and one for the overlaid text, solid.

body { background: red; }_x000D_
_x000D_
.box { position: relative; z-index: 1; }_x000D_
.box .back {_x000D_
    position: absolute; z-index: 1;_x000D_
    top: 0; left: 0; width: 100%; height: 100%;_x000D_
    background: white; opacity: 0.75;_x000D_

I use this method to solve this problem Maybe you can try it

"Enable ssh-agent"

1. Download git

http://git-scm.com/

1. Install it

2. Enable ssh-agent

C:\Program Files\Git\cmd

start-ssh-agent

The message disapper after I agent enabled Hope this will help you

Note that %in% returns a logical vector of TRUE and FALSE. To negate it, you can use ! in front of the logical statement:

SE_CSVLinelist_filtered <- filter(SE_CSVLinelist_clean, 
 !where_case_travelled_1 %in% 
   c('Outside Canada','Outside province/territory of residence but within Canada'))

Regarding your original approach with -c(...), - is a unary operator that "performs arithmetic on numeric or complex vectors (or objects which can be coerced to them)" (from help("-")). Since you are dealing with a character vector that cannot be coerced to numeric or complex, you cannot use -.

How about this: It is Somewhat Efficient & Somewhat Simple. Only need to join '2' parts of url path:

def UrlJoin(a , b):
    a, b = a.strip(), b.strip()
    a = a if a.endswith('/') else a + '/'
    b = b if not b.startswith('/') else b[1:]
    return a + b

OR: More Conventional, but Not as efficient if joining only 2 url parts of a path.

def UrlJoin(*parts):
    return '/'.join([p.strip().strip('/') for p in parts])

Test Cases:

>>> UrlJoin('https://example.com/', '/TestURL_1')
'https://example.com/TestURL_1'

>>> UrlJoin('https://example.com', 'TestURL_2')
'https://example.com/TestURL_2'

Note: I may be splitting hairs here, but it is at least good practice and potentially more readable.

Installs package from git and save to your bower.json dependency block.

1. bower register package-name git-endpoint#version
2. install package-name --save

(--save will save the package name version in the bower.json file inside the dependency block).

Reference

You should use IS rather than = for comparing to NULL.

UPDATE `smartmeter_usage`.`users_reporting`
SET panel_id = 3
WHERE panel_id IS null

The LIMIT clause in MySQL when applied to an update does not permit an offset to be specified.

Here's my non-silly example, (from Stevens APITUE) for Unix system calls which may be interrupted by a signal.

restart:
    if (system_call() == -1) {
        if (errno == EINTR) goto restart;

        // handle real errors
    }

The alternative is a degenerate loop. This version reads like English "if the system call was interrupted by a signal, restart it".

Example: index = False

import pandas as pd

writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save() 

the return statement exits from the current function and exit() exits from the program

they are the same when used in main() function

also return is a statement while exit() is a function which requires stdlb.h header file

Here's one approach using a regular expression:

$string =~ s/^\s+|\s+$//g ;     # remove both leading and trailing whitespace

Perl 6 will include a trim function:

$string .= trim;

Hope this helps someone who's still struggling.

Don't keep your table inside any container. Make the table's wrapper your container after the table's rendered. I know this might be invalid at places where you have something else along with the table but then you could always append that content back.

For me,this problem arises if you have a sidebar and a container that is actually an offset to that sidebar.

$(YourTableName+'_wrapper').addClass('mycontainer');

(I added a panel panel-default)
And your class :

.mycontainer{background-color:white;padding:5px;}

This will iterate over all descendant files, not just the immediate children of the directory:

import os

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        #print os.path.join(subdir, file)
        filepath = subdir + os.sep + file

        if filepath.endswith(".asm"):
            print (filepath)

You can use deletgate with scp too:

- name: Copy file to another server
  become: true
  shell: "scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null admin@{{ inventory_hostname }}:/tmp/file.yml /tmp/file.yml"
  delegate_to: other.example.com

Because of delegate the command is run on the other server and it scp's the file to itself.

Only if you want to destroy previous session :

<?php
    if(!isset($_SESSION)) 
    { 
        session_start(); 
    }
    else
    {
        session_destroy();
        session_start(); 
    }
?>

or you can use

unset($_SESSION['variable_session _data'])

to destroy a particular session variable.

s = "I     am having  a   very  nice  23!@$      day. "
sum([i.strip(string.punctuation).isalpha() for i in s.split()])

The statement above will go through each chunk of text and remove punctuations before verifying if the chunk is really string of alphabets.

I created jquery.backgroundSize.js: a 1.5K jquery plugin that can be used as a IE8 fallback for "cover" and "contain" values. Have a look at the demo.

Solving your problem could be as simple as:

$("h2#news").css({backgroundSize: "cover"});

The compiler needs to know the size of the second dimension in your two dimensional array. For example:

void print_graph(g_node graph_node[], double weight[][5], int nodes);

You can use readonly instead. Following would do the trick for you.

<input type="text" class="details-dialog" style="background-color: #bbbbbb" readonly>

But you need to note the following. Depends on your business requirement, you can use it.

A readonly element is just not editable, but gets sent when the according form submits. A disabled element isn't editable and isn't sent on submit.

simplexml_load_file() interprets an XML file (either a file on your disk or a URL) into an object. What you have in $feed is a string.

You have two options:

• Use file_get_contents() to get the XML feed as a string, and use e simplexml_load_string():

  $feed = file_get_contents('...');
  $items = simplexml_load_string($feed);
  

• Load the XML feed directly using simplexml_load_file():

  $items = simplexml_load_file('...');
  

This one works very well for me.

   $("#checkall").click(function() {
       var fruits = $("input[name=fruits\\[\\]]");
        fruits.prop("checked", $(this).prop("checked"));
    });

If you don't want to list all your columns in CTE, another way to do this would be to use outer apply:

select
    s.logcount, s.logUserID, s.maxlogtm,
    a.daysdiff
from statslogsummary as s
    outer apply (select datediff(day, s.maxlogtm, getdate()) as daysdiff) as a
where a.daysdiff > 120

Given your factorGenerator function, here is a divisorGen that should work:

def divisorGen(n):
    factors = list(factorGenerator(n))
    nfactors = len(factors)
    f = [0] * nfactors
    while True:
        yield reduce(lambda x, y: x*y, [factors[x][0]**f[x] for x in range(nfactors)], 1)
        i = 0
        while True:
            f[i] += 1
            if f[i] <= factors[i][1]:
                break
            f[i] = 0
            i += 1
            if i >= nfactors:
                return

The overall efficiency of this algorithm will depend entirely on the efficiency of the factorGenerator.

I would just change a few details (no need to use the modulo operator here...):

public class Mythread {

    public static void main(String[] args) {
        Runnable r = new Runnable1();
        Thread t = new Thread(r);
        Runnable r2 = new Runnable2();
        Thread t2 = new Thread(r2);
        t.start();
        t2.start();
    }
}

class Runnable2 implements Runnable{
    public void run(){
        for(int i=0;i<11;i+=2) {
            System.out.println(i);
        }
    }
}

class Runnable1 implements Runnable{
    public void run(){
        for(int i=1;i<=11;i+=2) {
           System.out.println(i);
        }
    }
}

I figured it out and posted the answer in Can't run Business Intelligence Development Studio, file is not found.

I had this same problem. I am running .NET framework 3.5, SQL Server 2005, and Visual Studio 2008. While I was trying to run SQL Server Business Intelligence Development Studio the icon was grayed out and the devenv.exe file was not found.

I hope this helps.

There are several solutions to this but this is the pattern I tend to use.

// Form 1
// inside the button click event
using(Form2 form2 = new Form2()) 
{
    if(form2.ShowDialog() == DialogResult.OK) 
    {
        someControlOnForm1.Text = form2.TheValue;
    }
}

And...

// Inside Form2
// Create a public property to serve the value
public string TheValue 
{
    get { return someTextBoxOnForm2.Text; }
}

To use Uninstall-Anaconda.exe in C:\Users\username\Anaconda3 is a good way.

In addition to above points, it would be good to know that:

1. A task is by default a background task. You cannot have a foreground task. On the other hand a thread can be background or foreground (Use IsBackground property to change the behavior).
2. Tasks created in thread pool recycle the threads which helps save resources. So in most cases tasks should be your default choice.
3. If the operations are quick, it is much better to use a task instead of thread. For long running operations, tasks do not provide much advantages over threads.

This looks like a problem with the svn:mergeinfo property getting out of wack between the branch and the trunk.

Which leads to the following questions (forgive my command line instructions as I done use tortoise much):

1. Are you merging at the trunk root level or the sub folder level? In my experience it is always best to do at the root level, this way the whole trunk thinks it has been merged to rather than just part (this seems to confuse svn greatly in 1.5.0)

2. My next question is were you using the --reintergrate parameter? I can never remember how to get to this in tortoise, but when you are going back to the trunk from a branch then you should use this parameter.

3. Have you merged the trunk into the branch before you have reintegrated? This can help remove conflicts that you may see when you merge back?

4. Have you got any svn:mergeinfo properties on the branch that are not at the root level? This I have found always causes problems. You can always find this out by going svn -R pg svn:mergeinfo. You can then record the locations and revisions that were below the root, if you find them relevant then move them to the root by svn merge --record-only -r start:end <location> and then delete them from the sub root locations with svn pd svn:mergeinfo <location> You then need to commit these changes

5. Once you have all that is done try merging again.

You can do two things here either move the onSubmit attribute to the form tag, or change the onSubmit event to an onCLick event.

Option 1

<form name="loginform" onSubmit="return validateForm();">

Option 2

<input type="submit" value="Login" onClick="return validateForm();" />

.shape() gives the actual shape of your array in terms of no of elements in it, No of rows/No of Columns. The answer you get is in the form of tuples.

For Example: 1D ARRAY:

d=np.array([1,2,3,4])
print(d)
(1,)

Output: (4,) ie the number4 denotes the no of elements in the 1D Array.

2D Array:

e=np.array([[1,2,3],[4,5,6]])   
print(e)
(2,3)

Output: (2,3) ie the number of rows and the number of columns.

The number of elements in the final output will depend on the number of rows in the Array....it goes on increasing gradually.

I work on PHP and have used Swagger 2.0 to document the APIs. The Swagger Document is created on the fly (at least that is what I use in PHP). The document is generated in the JSON format.

This can be imported into Postman as follow.

1. Click on the 'Import' button in the top left corner of Postman UI.
2. You will see multiple options to import the API doc. Click on the 'Paste Raw Text'.
3. Paste the JSON format in the text area and click import.
4. You will see all your APIs as 'Postman Collection' and can use it from the Postman.

You can also use 'Import From Link'. Here paste the URL which generates the JSON format of the APIs from the Swagger or any other API Document tool.

This is my Document (JSON) generation file. It's in PHP. I have no idea of JAVA along with Swagger.

Marco's answer above is correct, but just to expand on the question of "under what context"...

frame - this is the property you most often use for normal iPhone applications. most controls will be laid out relative to the "containing" control so the frame.origin will directly correspond to where the control needs to display, and frame.size will determine how big to make the control.

center - this is the property you will likely focus on for sprite based games and animations where movement or scaling may occur. By default animation and rotation will be based on the center of the UIView. It rarely makes sense to try and manage such objects by the frame property.

bounds - this property is not a positioning property, but defines the drawable area of the UIView "relative" to the frame. By default this property is usually (0, 0, width, height). Changing this property will allow you to draw outside of the frame or restrict drawing to a smaller area within the frame. A good discussion of this can be found at the link below. It is uncommon for this property to be manipulated unless there is specific need to adjust the drawing region. The only exception is that most programs will use the [[UIScreen mainScreen] bounds] on startup to determine the visible area for the application and setup their initial UIView's frame accordingly.

Why is there an frame rectangle and an bounds rectangle in an UIView?

Hopefully this helps clarify the circumstances where each property might get used.

Do you have a Python virtual environment that you need to enter before you run manage.py?

I ran into this error myself, and that was the problem.

Very Simple Solution

One that I've used for years.

Script (add to your .bashrc or .bash_profile)

# capture the output of a command so it can be retrieved with ret
cap () { tee /tmp/capture.out}

# return the output of the most recent command that was captured by cap
ret () { cat /tmp/capture.out }

Usage

$ find . -name 'filename' | cap
/path/to/filename

$ ret
/path/to/filename

I tend to add | cap to the end of all of my commands. This way when I find I want to do text processing on the output of a slow running command I can always retrieve it with res.

You could use threading or multiprocessing.

Due to peculiarities of CPython, threading is unlikely to achieve true parallelism. For this reason, multiprocessing is generally a better bet.

Here is a complete example:

from multiprocessing import Process

def func1():
  print 'func1: starting'
  for i in xrange(10000000): pass
  print 'func1: finishing'

def func2():
  print 'func2: starting'
  for i in xrange(10000000): pass
  print 'func2: finishing'

if __name__ == '__main__':
  p1 = Process(target=func1)
  p1.start()
  p2 = Process(target=func2)
  p2.start()
  p1.join()
  p2.join()

The mechanics of starting/joining child processes can easily be encapsulated into a function along the lines of your runBothFunc:

def runInParallel(*fns):
  proc = []
  for fn in fns:
    p = Process(target=fn)
    p.start()
    proc.append(p)
  for p in proc:
    p.join()

runInParallel(func1, func2)

To understand the difference between a simulator and an emulator, keep in mind that a simulator tries to mimic the behavior of a real device. For example, in the case of the iOS Simulator, it simulates the real behavior of an actual iPhone/iPad device. However, the Simulator itself uses the various libraries installed on the Mac (such as QuickTime) to perform its rendering so that the effect looks the same as an actual iPhone. In addition, applications tested on the Simulator are compiled into x86 code, which is the byte-code understood by the Simulator. A real iPhone device, conversely, uses ARM-based code.

In contrast, an emulator emulates the working of a real device. Applications tested on an emulator are compiled into the actual byte-code used by the real device. The emulator executes the application by translating the byte-code into a form that can be executed by the host computer running the emulator.

To understand the subtle difference between simulation and emulation, imagine you are trying to convince a child that playing with knives is dangerous. To simulate this, you pretend to cut yourself with a knife and groan in pain. To emulate this, you actually cut yourself.

I found simple solution to get current date without any parsing error.

Calendar calendar;
calendar = Calendar.getInstance();
String customDate = "" + calendar.get(Calendar.YEAR) + "-" + (calendar.get(Calendar.MONTH) + 1) + "-" + calendar.get(Calendar.DAY_OF_MONTH);

With the Python library pandas, you can easily create column names and infer data types from a csv file.

from sqlalchemy import create_engine
import pandas as pd

engine = create_engine('postgresql://user:pass@localhost/db_name')
df = pd.read_csv('/path/to/csv_file')
df.to_sql('pandas_db', engine)

The if_exists parameter can be set to replace or append to an existing table, e.g. df.to_sql('pandas_db', engine, if_exists='replace'). This works for additional input file types as well, docs here and here.

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

{$variable|@debug_print_var nofilter} and you not need to add "<pre>" tags

{$variable|var_dump} show you more (but worse formatting) because debug_print_var not showing private variable in object!

You can do that using at. You can try out the following simple example:

const size_t N = 20;
std::vector<int> vec(N);
try {
    vec.at(N - 1) = 7;
} catch (std::out_of_range ex) {
    std::cout << ex.what() << std::endl;
}
assert(vec.at(N - 1) == 7);

Notice that method at returns an allocator_type::reference, which is that case is a int&. Using at is equivalent to assigning values like vec[i]=....

There is a difference between at and insert as it can be understood with the following example:

const size_t N = 8;
std::vector<int> vec(N);
for (size_t i = 0; i<5; i++){
    vec[i] = i + 1;
}

vec.insert(vec.begin()+2, 10);

If we now print out vec we will get:

1 2 10 3 4 5 0 0 0

If, instead, we did vec.at(2) = 10, or vec[2]=10, we would get

1 2 10 4 5 0 0 0

May be in a situation where you are creating a new mysqli object.

$MyConnection = new mysqli($hn, $un, $pw, $db);

but even after you close the object

$MyConnection->close();

if you will use print_r() to check the contents of $MyConnection, you will get an error as below:

Error:
mysqli Object

Warning: print_r(): Property access is not allowed yet in /path/to/program on line ..
( [affected_rows] => [client_info] => [client_version] =>.................)

in which case you can't use unlink() because unlink() will require a path name string but in this case $MyConnection is an Object.

So you have another choice of setting its value to null:

$MyConnection = null;

now things go right, as you have expected. You don't have any content inside the variable $MyConnection as well as you already cleaned up the mysqli Object.

It's a recommended practice to close the Object before setting the value of your variable to null.

This thread is quite old, but currently you can do this: much cleaner imho

May be not for all cases (especially if you have several NIC's), this will help:

hostname -I | awk '{ print $1 }'

Try this example

$json = '{"foo-bar": 12345}';

$obj = json_decode($json);
print $obj->{'foo-bar'}; // 12345

NB - two negatives makes a positive . :)

Run the commands below on your project..

npm rm -rf node_modules && npm rm package-lock.json && npm rm -rf ~/.npm && npm install --update-binary --no-shrinkwrap

Beware that when the mounted event is fired on a component, not all Vue components are replaced yet, so the DOM may not be final yet.

To really simulate the DOM onload event, i.e. to fire after the DOM is ready but before the page is drawn, use vm.$nextTick from inside mounted:

mounted: function () {
  this.$nextTick(function () {
    // Will be executed when the DOM is ready
  })
}

I just faced the same issue, I managed to make it work on my machine, however the change I did is not the same way it is mentioned in the documentation so it could be an issue of angular version routing module, mine is Angular 7

It only worked when I changed the lazy module main route entry path with same path as configured at the app-routes.ts

routes = [{path:'', redirectTo: '\home\default', pathMatch: 'full'},
           {path: '', 
           children: [{
             path:'home',
             loadChildren :'lazy module path'      
           }]

         }];

 routes configured at HomeModule
 const routes = [{path: 'home', redirectTo: 'default', pathMatch: 'full'},
             {path: 'default', component: MyPageComponent},
            ]

 instead of 
 const routes = [{path: '', redirectTo: 'default', pathMatch: 'full'},
                   {path: 'default', component: MyPageComponent},
                ]

[Fixed] Server version: 10.1.38-MariaDB - mariadb.org binary distribution

Go to: C:\xampp\mysql\bin open my.ini in notepad and find [mysqld] (line number 27) then after this line(line no 28) just type: skip-grant-tables

save the file and then reload the phpmyadmin page.It worked for me.

def function(a):
    if a == '1':
        print ('1a')
    elif a == '2':
        print ('2a')
    else:
        print ('3a')

One line version:

String text = ((Spinner)findViewById(R.id.spinner)).getSelectedItem().toString();

UPDATE: You can remove casting if you use SDK 26 (or newer) to compile your project.

String text = findViewById(R.id.spinner).getSelectedItem().toString();

You can use:

type text1.txt >> combine.txt
echo >> combine.txt
type text2.txt >> combine.txt

or something like this:

echo blah >> combine.txt
echo blah2 >> combine.txt
echo >> combine.txt
echo other >> combine.txt

Here's a way, not recommended though

class Weak {
private:
    string name;

public:
    void setName(const string& name) {
        this->name = name;
    }

    string getName()const {
        return this->name;
    }

};

struct Hacker {
    string name;
};

int main(int argc, char** argv) {

    Weak w;
    w.setName("Jon");
    cout << w.getName() << endl;
    Hacker *hackit = reinterpret_cast<Hacker *>(&w);
    hackit->name = "Jack";
    cout << w.getName() << endl;

}

It's in https://console.firebase.google.com/project/(your-project-id)/settings/cloudmessaging

You can find the API KEY in:

(gear-next-to-project-name) > Project Settings > Cloud Messaging

Server Key is the API key.

Try using an AppSettingsSection instead of a NameValueCollection. Something like this:

var section = (AppSettingsSection)config.GetSection(sectionName);
string results = section.Settings[key].Value;

I sugges to use the Apache Commons CSV https://commons.apache.org/proper/commons-csv/

Here is one example:

    Path currentRelativePath = Paths.get("");
    String currentPath = currentRelativePath.toAbsolutePath().toString();
    String csvFile = currentPath + "/pathInYourProject/test.csv";

    Reader in;
    Iterable<CSVRecord> records = null;
    try
    {
        in = new FileReader(csvFile);
        records = CSVFormat.EXCEL.withHeader().parse(in); // header will be ignored
    }
    catch (IOException e)
    {
        e.printStackTrace();
    }

    for (CSVRecord record : records) {
        String line = "";
        for ( int i=0; i < record.size(); i++)
        {
            if ( line == "" )
                line = line.concat(record.get(i));
            else
                line = line.concat("," + record.get(i));
        }
        System.out.println("read line: " + line);
    }

It automaticly recognize , and " but not ; (maybe it can be configured...).

My example file is:

col1,col2,col3
val1,"val2",val3
"val4",val5
val6;val7;"val8"

And output is:

read line: val1,val2,val3
read line: val4,val5
read line: val6;val7;"val8"

Last line is considered like one value.

As Scobal's post implies, the datepicker is looking for a Date object - not just a string! So, to modify your example code to do what you want:

var queryDate = new Date('2009/11/01'); // Dashes won't work
$('#datePicker').datepicker('setDate', queryDate);

Here is a simple letter-range implementation:

Code

def letter_range(start, stop="{", step=1):
    """Yield a range of lowercase letters.""" 
    for ord_ in range(ord(start.lower()), ord(stop.lower()), step):
        yield chr(ord_)

Demo

list(letter_range("a", "f"))
# ['a', 'b', 'c', 'd', 'e']

list(letter_range("a", "f", step=2))
# ['a', 'c', 'e']

Since upgrading my typings to react 0.14.43 (I'm not sure exactly when this was introduced), the React.FormEvent type is now generic and this removes the need for a cast.

import React = require('react');

interface ITestState {
    selectedValue: string;
}

export class Test extends React.Component<{}, ITestState> {

    constructor() {
        super();
        this.state = { selectedValue: "A" };
    }

    change(event: React.FormEvent<HTMLSelectElement>) {
        // No longer need to cast to any - hooray for react!
        var safeSearchTypeValue: string = event.currentTarget.value;

        console.log(safeSearchTypeValue); // in chrome => B

        this.setState({
            selectedValue: safeSearchTypeValue
        });
    }

    render() {
        return (
            <div>
                <label htmlFor="searchType">Safe</label>
                <select className="form-control" id="searchType" onChange={ e => this.change(e) } value={ this.state.selectedValue }>
                    <option value="A">A</option>
                    <option value="B">B</option>
                </select>
                <h1>{this.state.selectedValue}</h1>
            </div>
        );
    }
}

Power of extension

extension Double {
    var asNumber:String {
        if self >= 0 {
            var formatter = NSNumberFormatter()
            formatter.numberStyle = .NoStyle
            formatter.percentSymbol = ""
            formatter.maximumFractionDigits = 1
            return "\(formatter.stringFromNumber(self)!)"
        }
        return ""
    }
}

let velocity:Float = 12.32982342034

println("The velocity is \(velocity.toNumber)")

Output: The velocity is 12.3

You can use cut to access the second field:

cut -f2

Edit: Sorry, didn't realise that SVN doesn't use tabs in its output, so that's a bit useless. You can tailor cut to the output but it's a bit fragile - something like cut -c 10- would work, but the exact value will depend on your setup.

Another option is something like: sed 's/.\s\+//'

Try getppid() if you want your C program to print your shell's PID.

The terms resource and endpoint are often used synonymously. But in fact they do not mean the same thing.

The term endpoint is focused on the URL that is used to make a request.
The term resource is focused on the data set that is returned by a request.

Now, the same resource can often be accessed by multiple different endpoints.
Also the same endpoint can return different resources, depending on a query string.

Let us see some examples:

Different endpoints accessing the same resource

Have a look at the following examples of different endpoints:

/api/companies/5/employees/3
/api/v2/companies/5/employees/3
/api/employees/3

They obviously could all access the very same resource in a given API.

Also an existing API could be changed completely. This could lead to new endpoints that would access the same old resources using totally new and different URLs:

/api/employees/3
/new_api/staff/3

One endpoint accessing different resources

If your endpoint returns a collection, you could implement searching/filtering/sorting using query strings. As a result the following URLs all use the same endpoint (/api/companies), but they can return different resources (or resource collections, which by definition are resources in themselves):

/api/companies
/api/companies?sort=name_asc
/api/companies?location=germany
/api/companies?search=siemens

So far I have found two quick ways in cmd linux

1. Use old school mail

mail -s "$(echo -e "This is Subject\nContent-Type: text/html")" [email protected] < mytest.html

1. Use mutt

mutt -e "my_hdr Content-Type: text/html" [email protected] -s "subject" < mytest.html

I notice that Entity Framework 6.1 pointed at MSSQL does automatically add indexes on foreign keys.

Unfortunately, the

(falseValue, trueValue)[test]

solution doesn't have short-circuit behaviour; thus both falseValue and trueValue are evaluated regardless of the condition. This could be suboptimal or even buggy (i.e. both trueValue and falseValue could be methods and have side-effects).

One solution to this would be

(lambda: falseValue, lambda: trueValue)[test]()

(execution delayed until the winner is known ;)), but it introduces inconsistency between callable and non-callable objects. In addition, it doesn't solve the case when using properties.

And so the story goes - choosing between 3 mentioned solutions is a trade-off between having the short-circuit feature, using at least ?ython 2.5 (IMHO not a problem anymore) and not being prone to "trueValue-evaluates-to-false" errors.
