Depending on box sizing width 100% might not always be the best option. I would suggest

 width:100vw;
 overflow-x: scroll;

This can be applied in the context of body, html as has been suggested or you could just wrap the content that is having an issue in a div with these settings applied.

a simple way is:

create a fake "*.UDL" file on desktop

(UDL files are described here: https://msdn.microsoft.com/en-us/library/e38h511e(v=vs.71).aspx.

in case you can also customized it as explained there. )

POD is the official way to do multi line comments in Perl,

• see Multi-line comments in perl code and
• Better ways to make multi-line comments in Perl for more detail.

From faq.perl.org[perlfaq7]

• How can I comment out a large block of Perl code?

The quick-and-dirty way to comment out more than one line of Perl is to surround those lines with Pod directives. You have to put these directives at the beginning of the line and somewhere where Perl expects a new statement (so not in the middle of statements like the # comments). You end the comment with =cut, ending the Pod section:

=pod

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=cut

The quick-and-dirty method only works well when you don't plan to leave the commented code in the source. If a Pod parser comes along, your multiline comment is going to show up in the Pod translation. A better way hides it from Pod parsers as well.

The =begin directive can mark a section for a particular purpose. If the Pod parser doesn't want to handle it, it just ignores it. Label the comments with comment. End the comment using =end with the same label. You still need the =cut to go back to Perl code from the Pod comment:

=begin comment

my $object = NotGonnaHappen->new();

ignored_sub();

$wont_be_assigned = 37;

=end comment

=cut

New one for you Guys !

During my Gulp minification process

<!-- build:css /css/project-mini.css -->
    <link rel="stylesheet" href="css/main.css"/>
    <link rel="stylesheet" href="css/splash.css"/>
    <link rel="stylesheet" href="css/header.css"/>
    <link rel="stylesheet" href="css/print.css" media="print"/>
<!-- endbuild -->

Last CSS file was for print and the generated output gave me

    <link rel="stylesheet" href="css/project-mini.css" media="print"/>

So because of media="print" all CSS rules were skipped !

easiest way to do this is put after that view where you want bottom border

    <?xml version="1.0" encoding="utf-8"?>
    <View
    android:layout_width="match_parent"
    android:layout_height="1dp"
    android:background="@color/colorPrimary" />

The reason for the collision seems to be because, by default, the context root, "/", is to be handled by org.apache.catalina.servlets.DefaultServlet. This servlet is intended to handle requests for static resources.

If you decide to bump it out of the way with your own servlet, with the intent of handling dynamic requests, that top-level servlet must also carry out any tasks accomplished by catalina's original "DefaultServlet" handler.

If you read through the tomcat docs, they make mention that True Apache (httpd) is better than Apache Tomcat for handling static content, since it is purpose built to do just that. My guess is because Tomcat by default uses org.apache.catalina.servlets.DefaultServlet to handle static requests. Since it's all wrapped up in a JVM, and Tomcat is intended to as a Servlet/JSP container, they probably didn't write that class as a super-optimized static content handler. It's there. It gets the job done. Good enough.

But that's the thing that handles static content and it lives at "/". So if you put anything else there, and that thing doesn't handle static requests, WHOOPS, there goes your static resources.

I've been searching high and low for the same answer and the answer I'm getting everywhere is "if you don't want it to do that, don't do that".

So long story short, your configuration is displacing the default static resource handler with something that isn't a static resource handler at all. You'll need to try a different configuration to get the results you're looking for (as will I).

It's the index column, pass pd.to_csv(..., index=False) to not write out an unnamed index column in the first place, see the to_csv() docs.

Example:

In [37]:
df = pd.DataFrame(np.random.randn(5,3), columns=list('abc'))
pd.read_csv(io.StringIO(df.to_csv()))

Out[37]:
   Unnamed: 0         a         b         c
0           0  0.109066 -1.112704 -0.545209
1           1  0.447114  1.525341  0.317252
2           2  0.507495  0.137863  0.886283
3           3  1.452867  1.888363  1.168101
4           4  0.901371 -0.704805  0.088335

compare with:

In [38]:
pd.read_csv(io.StringIO(df.to_csv(index=False)))

Out[38]:
          a         b         c
0  0.109066 -1.112704 -0.545209
1  0.447114  1.525341  0.317252
2  0.507495  0.137863  0.886283
3  1.452867  1.888363  1.168101
4  0.901371 -0.704805  0.088335

You could also optionally tell read_csv that the first column is the index column by passing index_col=0:

In [40]:
pd.read_csv(io.StringIO(df.to_csv()), index_col=0)

Out[40]:
          a         b         c
0  0.109066 -1.112704 -0.545209
1  0.447114  1.525341  0.317252
2  0.507495  0.137863  0.886283
3  1.452867  1.888363  1.168101
4  0.901371 -0.704805  0.088335

The answers with the text-transformation:uppercase styling will not send uppercased data to the server on submit - what you might expect. You can do something like this instead:

For your input HTML use onkeydown:

<input name="yourInput" onkeydown="upperCaseF(this)"/>

In your JavaScript:

function upperCaseF(a){
    setTimeout(function(){
        a.value = a.value.toUpperCase();
    }, 1);
}

With upperCaseF() function on every key press down, the value of the input is going to turn into its uppercase form.

I also added a 1ms delay so that the function code block triggers after the keydown event occured.

UPDATE

Per remommendation from Dinei, you can use oninput event instead of onkeydown and get rid of setTimeout.

For your input HTML use oninput:

<input name="yourInput" oninput="this.value = this.value.toUpperCase()"/>

I just learned something new thanks to Artiso. I gave each module a name in the properties box. These names were also what I declared in the module. When I tried to call my second module, I kept getting an error: Compile error: Expected variable or procedure, not module

After reading Artiso's comment above about not having the same names, I renamed my second module, called it from the first, and problem solved. Interesting stuff! Thanks for the info Artiso!

In case my experience is unclear:

Module Name: AllFSGroupsCY Public Sub AllFSGroupsCY()

Module Name: AllFSGroupsPY Public Sub AllFSGroupsPY()

From AllFSGroupsCY()

Public Sub FSGroupsCY()

    AllFSGroupsPY 'will error each time until the properties name is changed

End Sub

Case: Light text with jaggy web font on dark background Firefox (v35)/Windows
Example: Google Web Font Ruda

Surprising solution -
adding following property to the applied selectors:

selector {
    text-shadow: 0 0 0;
}

Actually, result is the same just with text-shadow: 0 0;, but I like to explicitly set blur-radius.

It's not an universal solution, but might help in some cases. Moreover I haven't experienced (also not thoroughly tested) negative performance impacts of this solution so far.

Your function worked for me after changing its declaration to this ...

Function processArr(Arr As Variant) As String

You could also consider a ParamArray like this ...

Function processArr(ParamArray Arr() As Variant) As String
    'Dim N As Variant
    Dim N As Long
    Dim finalStr As String
    For N = LBound(Arr) To UBound(Arr)
        finalStr = finalStr & Arr(N)
    Next N
    processArr = finalStr
End Function

And then call the function like this ...

processArr("foo", "bar")

var JSON = [{"name":"cat"}, {"name":"dog"}];

The JSON variable refers to an array of object with one property called "name". I don't know of the best way but this is what I do?

var hasMatch =false;

for (var index = 0; index < JSON.length; ++index) {

 var animal = JSON[index];

 if(animal.Name == "dog"){
   hasMatch = true;
   break;
 }
}

You could use functor as third argument of std::sort, or you could define operator< in your class.

struct X {
    int x;
    bool operator<( const X& val ) const { 
        return x < val.x; 
    }
};

struct Xgreater
{
    bool operator()( const X& lx, const X& rx ) const {
        return lx.x < rx.x;
    }
};

int main () {
    std::vector<X> my_vec;

    // use X::operator< by default
    std::sort( my_vec.begin(), my_vec.end() );

    // use functor
    std::sort( my_vec.begin(), my_vec.end(), Xgreater() );
}

I found the information found at http://help.infragistics.com/Help/NetAdvantage/jQuery/2013.1/CLR4.0/html/igOlapXmlaDataSource_Configuring_IIS_for_Cross_Domain_OLAP_Data.html to be very helpful in setting up HTTP OPTIONS for a WCF service in IIS 7.

I added the following to my web.config and then moved the OPTIONSVerbHandler in the IIS 7 'hander mappings' list to the top of the list. I also gave the OPTIONSVerbHander read access by double clicking the hander in the handler mappings section then on 'Request Restrictions' and then clicking on the access tab.

Unfortunately I quickly found that IE doesn't seem to support adding headers to their XDomainRequest object (setting the Content-Type to text/xml and adding a SOAPAction header).

Just wanted to share this as I spent the better part of a day looking for how to handle it.

<system.webServer>
    <httpProtocol>
        <customHeaders>
            <add name="Access-Control-Allow-Origin" value="*" />
            <add name="Access-Control-Allow-Methods" value="GET,POST,OPTIONS" />
            <add name="Access-Control-Allow-Headers" value="Content-Type, soapaction" />
        </customHeaders>
    </httpProtocol>

Programming to an interface is saying, "I need this functionality and I don't care where it comes from."

Consider (in Java), the List interface versus the ArrayList and LinkedList concrete classes. If all I care about is that I have a data structure containing multiple data items that I should access via iteration, I'd pick a List (and that's 99% of the time). If I know that I need constant-time insert/delete from either end of the list, I might pick the LinkedList concrete implementation (or more likely, use the Queue interface). If I know I need random access by index, I'd pick the ArrayList concrete class.

It is not possible in on step or you need to keep the reference to the array. If you can change the reference this can help:

      String[] n = new String[]{"google","microsoft","apple"};
      final List<String> list =  new ArrayList<String>();
      Collections.addAll(list, n); 
      list.remove("apple");
      n = list.toArray(new String[list.size()]);

I not recommend the following but if you worry about performance:

      String[] n = new String[]{"google","microsoft","apple"};
      final String[] n2 = new String[2]; 
      System.arraycopy(n, 0, n2, 0, n2.length);
      for (int i = 0, j = 0; i < n.length; i++)
      {
        if (!n[i].equals("apple"))
        {
          n2[j] = n[i];
          j++;
        }      
      }

I not recommend it because the code is a lot more difficult to read and maintain.

The most important concept to remember about the checked attribute is that it does not correspond to the checked property. The attribute actually corresponds to the defaultChecked property and should be used only to set the initial value of the checkbox. The checked attribute value does not change with the state of the checkbox, while the checked property does. Therefore, the cross-browser-compatible way to determine if a checkbox is checked is to use the property

All below methods are possible

elem.checked 

$(elem).prop("checked") 

$(elem).is(":checked") 

If you can't solve the problem for the rectangle try dividing the problem in to easier problems. Divide the rectangle into 2 triangles an check if the point is inside any of them like they explain in here

Essentially, you cycle through the edges on every two pairs of lines from a point. Then using cross product to check if the point is between the two lines using the cross product. If it's verified for all 3 points, then the point is inside the triangle. The good thing about this method is that it does not create any float-point errors which happens if you check for angles.

$srchDate = date_format(date_create_from_format('d/m/Y', $srchDate), 'Y/m/d');

This will work for you. You convert the String into a custom date format where you can specify to PHP what the original format of the String is that had been given to it. Now that it is a date format, you can convert it to PHP's default date format, which is the same that is used by MySQL.

The date can be converted in typescript to this format 'yyyy-MM-dd' by using Datepipe

import { DatePipe } from '@angular/common'
...
constructor(public datepipe: DatePipe){}
...
myFunction(){
 this.date=new Date();
 let latest_date =this.datepipe.transform(this.date, 'yyyy-MM-dd');
}

and just add Datepipe in 'providers' array of app.module.ts. Like this:

import { DatePipe } from '@angular/common'
...
providers: [DatePipe]

It seems that the compiler is better in optimizing a switch-statement than an if-statement.

The compiler doesn't know if the order of evaluating the if-statements is important to you, and can't perform any optimizations there. You could be calling methods in the if-statements, influencing variables. With the switch-statement it knows that all clauses can be evaluated at the same time and can put them in whatever order is most efficient.

Here's a small comparison:

I think that right implementations should be

public class Thing
{
    public int value;  

    public Thing (int x)
    {
        this.value = x;
    }

    @Override
    public boolean equals(Object object)
    {
        boolean sameSame = false;

        if (object != null && object instanceof Thing)
        {
            sameSame = this.value == ((Thing) object).value;
        }

        return sameSame;
    }
}

I'm using Ubuntu 18.04 LTS. Most of the time, when I change my java version, I also want to use the same javac version.
I use update-alternatives this way, using a java_home alternative instead :

Installation

Install every java version in /opt/java/<version>, for example

~$ ll /opt/java/
total 24
drwxr-xr-x 6 root root 4096 jan. 22 21:14 ./
drwxr-xr-x 9 root root 4096 feb.  7 13:40 ../
drwxr-xr-x  8 stephanecodes stephanecodes 4096 jan.   8  2019 jdk-11.0.2/
drwxr-xr-x  7 stephanecodes stephanecodes 4096 dec.  15  2018 jdk1.8.0_201/

Configure alternatives

~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk-11.0.2/ 100
~$ sudo update-alternatives --install /opt/java/current java_home /opt/java/jdk1.8.0_201 200

Declare JAVA_HOME (In this case, I use a global initialization script for this)

~$ sudo sh -c 'echo export JAVA_HOME=\"/opt/java/current\" >> environment.sh'

Log Out or restart Ubuntu (this will reload /etc/profile.d/environment.sh)

Usage

Change java version

Choose the version you want to use

~$ sudo update-alternatives --config java_home

There are 2 choices for the alternative java_home (providing /opt/java/current).

  Selection    Path                    Priority   Status
------------------------------------------------------------
  0            /opt/java/jdk-11.0.2     200       auto mode
  1            /opt/java/jdk-11.0.2     200       manual mode
* 2            /opt/java/jdk1.8.0_201   100       manual mode

Press <enter> to keep the current choice[*], or type selection number: 

Check version

~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

~$ javac -version
javac 11.0.2

Tip

Add the following line to ~/.bash_aliases file :

alias change-java-version="sudo update-alternatives --config java_home && java -version && javac -version"

Now use the change-java-version command to change java version

A random value?

If you want a random value, try

<?php
$value = mt_rand($min, $max);

mt_rand() will run a bit more random if you are using many random numbers in a row, or if you might ever execute the script more than once a second. In general, you should use mt_rand() over rand() if there is any doubt.

Iterators are first choice over operator[]. C++11 provides std::begin(), std::end() functions.

As your code uses just std::vector, I can't say there is much difference in both codes, however, operator [] may not operate as you intend to. For example if you use map, operator[] will insert an element if not found.

Also, by using iterator your code becomes more portable between containers. You can switch containers from std::vector to std::list or other container freely without changing much if you use iterator such rule doesn't apply to operator[].

You just need to get selenium package imported, that you can do from command prompt using the command

pip install selenium

When you have to use it in any IDE just import this package, no other documentation required to be imported

For Eg :

import selenium 
print(selenium.__filepath__)

This is just a general command you may use in starting to check the filepath of selenium

    using (FileStream fs = File.OpenRead(filename)) {
        Ude.CharsetDetector cdet = new Ude.CharsetDetector();
        cdet.Feed(fs);
        cdet.DataEnd();
        if (cdet.Charset != null) {
            Console.WriteLine("Charset: {0}, confidence: {1}", 
                 cdet.Charset, cdet.Confidence);
        } else {
            Console.WriteLine("Detection failed.");
        }
    }
}

The easiest way I have found is to dump the database to a text file, run a sed command to do the replace, and reload the database back into MySQL.

All commands below are bash on Linux.

Dump database to text file

mysqldump -u user -p databasename > ./db.sql

Run sed command to find/replace target string

sed -i 's/oldString/newString/g' ./db.sql

Reload the database into MySQL

mysql -u user -p databasename < ./db.sql

Easy peasy.

The easiest way to find a midnight:

Long time = new Date().getTime();
Date date = new Date(time - time % (24 * 60 * 60 * 1000));

Next day:

Date date = new Date(date.getTime() + 24 * 60 * 60 * 1000);

While the marked answer is correct there is a way of achieving this without exceptions. The service is returning Optional<T> of the searched object and this is mapped to HttpStatus.OK if found and to 404 if empty.

@Controller
public class SomeController {

    @RequestMapping.....
    public ResponseEntity<Object> handleCall() {
        return  service.find(param).map(result -> new ResponseEntity<>(result, HttpStatus.OK))
                .orElse(new ResponseEntity<>(HttpStatus.NOT_FOUND));
    }
}

@Service
public class Service{

    public Optional<Object> find(String param){
        if(!found()){
            return Optional.empty();
        }
        ...
        return Optional.of(data); 
    }

}

LIMIT allow you to skip any number of rows. It has two parameters, and first of them - how many rows to skip

You can try using jQuery with the Attribute Contains Prefix Selector.

$('[id|=q1_]')

Haven't tested it though.

Easiest way is to use System.Linq as previously described

using System.Linq;

public int GetHighestValue(List<MyTypes> list)
{
    return list.Count > 0 ? list.Max(t => t.Age) : 0; //could also return -1
}

This is also possible with a Dictionary

using System.Linq;

public int GetHighestValue(Dictionary<MyTypes, OtherType> obj)
{
    return obj.Count > 0 ? obj.Max(t => t.Key.Age) : 0; //could also return -1
}

I felt the below approach is very easy.

I have declared an interface for callback

public interface AsyncResponse {
    void processFinish(Object output);
}

Then created asynchronous Task for responding all type of parallel requests

 public class MyAsyncTask extends AsyncTask<Object, Object, Object> {

    public AsyncResponse delegate = null;//Call back interface

    public MyAsyncTask(AsyncResponse asyncResponse) {
        delegate = asyncResponse;//Assigning call back interfacethrough constructor
    }

    @Override
    protected Object doInBackground(Object... params) {

      //My Background tasks are written here

      return {resutl Object}

    }

    @Override
    protected void onPostExecute(Object result) {
        delegate.processFinish(result);
    }

}

Then Called the asynchronous task when clicking a button in activity Class.

public class MainActivity extends Activity{

    @Override
    public void onCreate(Bundle savedInstanceState) {

    Button mbtnPress = (Button) findViewById(R.id.btnPress);

    mbtnPress.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

Answer on an old question, this new post is posted on April the 4th 2013

To complete the answer of @misza, here a advanced method to check if cookies are enabled without page reloading. The problem with @misza is that it not always work when the php ini setting session.use_cookies is not true. Also the solution does not check if a session is already started.

I made this function and test it many times with in different situations and does the job very well.

    function suGetClientCookiesEnabled() // Test if browser has cookies enabled
    {
      // Avoid overhead, if already tested, return it
      if( defined( 'SU_CLIENT_COOKIES_ENABLED' ))
       { return SU_CLIENT_COOKIES_ENABLED; }

      $bIni = ini_get( 'session.use_cookies' ); 
      ini_set( 'session.use_cookies', 1 ); 

      $a = session_id();
      $bWasStarted = ( is_string( $a ) && strlen( $a ));
      if( !$bWasStarted )
      {
        @session_start();
        $a = session_id();
      }

   // Make a copy of current session data
  $aSesDat = (isset( $_SESSION ))?$_SESSION:array();
   // Now we destroy the session and we lost the data but not the session id 
   // when cookies are enabled. We restore the data later. 
  @session_destroy(); 
   // Restart it
  @session_start();

   // Restore copy
  $_SESSION = $aSesDat;

   // If no cookies are enabled, the session differs from first session start
  $b = session_id();
  if( !$bWasStarted )
   { // If not was started, write data to the session container to avoid data loss
     @session_write_close(); 
   }

   // When no cookies are enabled, $a and $b are not the same
  $b = ($a === $b);
  define( 'SU_CLIENT_COOKIES_ENABLED', $b );

  if( !$bIni )
   { @ini_set( 'session.use_cookies', 0 ); }

  //echo $b?'1':'0';
  return $b;
    }

Usage:

if( suGetClientCookiesEnabled())
 { echo 'Cookies are enabled!'; }
else { echo 'Cookies are NOT enabled!'; }

Important note: The function temporarily modify the ini setting of PHP when it not has the correct setting and restore it when it was not enabled. This is only to test if cookies are enabled. It can get go wrong when you start a session and the php ini setting session.use_cookies has an incorrect value. To be sure that the session is working correctly, check and/or set it before start a session, for example:

   if( suGetClientCookiesEnabled())
     { 
       echo 'Cookies are enabled!'; 
       ini_set( 'session.use_cookies', 1 ); 
       echo 'Starting session';
       @start_session(); 

     }
    else { echo 'Cookies are NOT enabled!'; }

Use this function:

$(".price").each(function(){
total_price += parseInt($(this).val());
});

You have to change delimiter before using triggers, stored procedures and so on.

delimiter //
create procedure ProG() 
begin 
SELECT * FROM hs_hr_employee_leave_quota;
end;//
delimiter ;

Basic example. First-half builds the frequency-map, second-half reduces it to a filtered list. Probably not as efficient as Dave's answer, but more versatile (like if you want to detect exactly two etc.)

List<Integer> duplicates = IntStream.of( 1, 2, 3, 2, 1, 2, 3, 4, 2, 2, 2 )
   .boxed()
   .collect( Collectors.groupingBy( Function.identity(), Collectors.counting() ) )
   .entrySet()
   .stream()
   .filter( p -> p.getValue() > 1 )
   .map( Map.Entry::getKey )
   .collect( Collectors.toList() );

I use a relative path solution,

./../../../../../images/img.png

every ../ will take you one folder up towards the root. Hope this helps..

Make the keydown even call multiple functions, with each function checking for a specific key and responding appropriately.

document.keydown = function (key) {

    checkKey("x");
    checkKey("y");
};

Another reason to the error may be if you are running a cron job that updates a subversion working copy and then has attempted to run a versioned script that was in a conflicted state after the update...

Using @bill-shirley answer with a little addition

function str_to_hex($string) {
$hexstr = unpack('H*', $string);
return array_shift($hexstr);
}
function hex_to_str($string) {
return hex2bin("$string");
}

Usage:

  $str = "Go placidly amidst the noise";
  $hexstr = str_to_hex($str);// 476f20706c616369646c7920616d6964737420746865206e6f697365
  $strstr = hex_to_str($str);// Go placidly amidst the noise

Not every jar file is executable.

Now, you need to import the classes, which are there under the jar, in your java file. For example,

import org.xml.sax.SAXException;

If you are working on an IDE, then you should refer its documentation. Or at least specify which one you are using here in this thread. It would definitely enable us to help you further.

And if you are not using any IDE, then please look at javac -cp option. However, it's much better idea to package your program in a jar file, and include all the required jars within that. Then, in order to execute your jar, like,

java -jar my_program.jar

you should have a META-INF/MANIFEST.MF file in your jar. See here, for how-to.

var otherInput = $(this).closest('.row').find('.inputQty');

That goes up to a row level, then back down to .inputQty.

I'm not quite sure I understand your question properly, but if you want to change the factor levels of cyl with mutate() you could do:

df <- mtcars %>% mutate(cyl = factor(cyl, levels = c(4, 6, 8)))

You would get:

#> str(df$cyl)
# Factor w/ 3 levels "4","6","8": 2 2 1 2 3 2 3 1 1 2 ...

I cheated, but I believe this is the only answer that addresses every requirement. Namely, this avoids the trailing CRLF, provides a place for the other operation to complete in the meantime, and properly redirects to stdout as necessary.

Re: Same navbar on multiple pages Aug 21, 2018 10:13 AM|LINK

As far as I know, there are multiple solution.

For example:

The Entire code for navigation bar is in nav.html file (without any html or body tag, only the code for navigation bar).

Then we could directly load it from the jquery without writing a lot of codes.

Like this:

    <!--Navigation bar-->
    <div id="nav-placeholder">

    </div>

    <script>
    $(function(){
      $("#nav-placeholder").load("nav.html");
    });
    </script>
    <!--end of Navigation bar-->

Solution2:

You could use JavaScript code to generate the whole nav bar.

Like this:

Javascript code:

$(function () {
    var bar = '';
    bar += '<nav class="navbar navbar-default" role="navigation">';
    bar += '<div class="container-fluid">';
    bar += '<div>';
    bar += '<ul class="nav navbar-nav">';
    bar += '<li id="home"><a href="home.html">Home</a></li>';
    bar += '<li id="index"><a href="index.html">Index</a></li>';
    bar += '<li id="about"><a href="about.html">About</a></li>';
    bar += '</ul>';
    bar += '</div>';
    bar += '</div>';
    bar += '</nav>';

    $("#main-bar").html(bar);

    var id = getValueByName("id");
    $("#" + id).addClass("active");
});

function getValueByName(name) {
    var url = document.getElementById('nav-bar').getAttribute('src');
    var param = new Array();
    if (url.indexOf("?") != -1) {
        var source = url.split("?")[1];
        items = source.split("&");
        for (var i = 0; i < items.length; i++) {
            var item = items[i];
            var parameters = item.split("=");
            if (parameters[0] == "id") {
                return parameters[1];
            }
        }
    }
}

I think we can write like this : $this->db->where('accommodation >=', minvalue); $this->db->where('accommodation <=', maxvalue);

//without dollar($) sign It's work for me :)

Instead of drop table TableA, you could delete all registers (delete from TableA;) and then populate original table with registers coming from TableA_Verify (insert into TAbleA select * from TAbleA_Verify). In this way you won't lost all references to original table (indexes,... )

CREATE TABLE TableA_Verify AS SELECT DISTINCT * FROM TableA;

DELETE FROM TableA;

INSERT INTO TableA SELECT * FROM TAbleA_Verify;

DROP TABLE TableA_Verify;

I would suggest using TRUNCATE TABLE, it's quicker and uses less resources than DELETE FROM xxx

Here's the related MSDN article

Try Following

DECLARE @formatted_datetime char(23)

I encountered this error when inheriting from an abstract class and not implementing all of the pure virtual methods in my subclass.

Cannot do the other way round (it's always good to know what you're doing)

With Version class that is contained in nv-ios-version project (Apache License, Version 2.0), it is easy to get and compare iOS version. An example code below dumps the iOS version and checks whether the version is greater than or equal to 6.0.

// Get the system version of iOS at runtime.
NSString *versionString = [[UIDevice currentDevice] systemVersion];

// Convert the version string to a Version instance.
Version *version = [Version versionWithString:versionString];

// Dump the major, minor and micro version numbers.
NSLog(@"version = [%d, %d, %d]",
    version.major, version.minor, version.micro);

// Check whether the version is greater than or equal to 6.0.
if ([version isGreaterThanOrEqualToMajor:6 minor:0])
{
    // The iOS version is greater than or equal to 6.0.
}

// Another way to check whether iOS version is
// greater than or equal to 6.0.
if (6 <= version.major)
{
    // The iOS version is greater than or equal to 6.0.
}

If I understand well, you want to Join ScheduleRequest with User and apply the in clause to the userName property of the entity User.

I'd need to work a bit on this schema. But you can try with this trick, that is much more readable than the code you posted, and avoids the Join part (because it handles the Join logic outside the Criteria Query).

List<String> myList = new ArrayList<String> ();
for (User u : usersList) {
    myList.add(u.getUsername());
}
Expression<String> exp = scheduleRequest.get("createdBy");
Predicate predicate = exp.in(myList);
criteria.where(predicate);

In order to write more type-safe code you could also use Metamodel by replacing this line:

Expression<String> exp = scheduleRequest.get("createdBy");

with this:

Expression<String> exp = scheduleRequest.get(ScheduleRequest_.createdBy);

If it works, then you may try to add the Join logic into the Criteria Query. But right now I can't test it, so I prefer to see if somebody else wants to try.

Not a perfect answer though may be code snippets might help.

public <T> List<T> findListWhereInCondition(Class<T> clazz,
            String conditionColumnName, Serializable... conditionColumnValues) {
        QueryBuilder<T> queryBuilder = new QueryBuilder<T>(clazz);
        addWhereInClause(queryBuilder, conditionColumnName,
                conditionColumnValues);
        queryBuilder.select();
        return queryBuilder.getResultList();

    }


private <T> void addWhereInClause(QueryBuilder<T> queryBuilder,
            String conditionColumnName, Serializable... conditionColumnValues) {

        Path<Object> path = queryBuilder.root.get(conditionColumnName);
        In<Object> in = queryBuilder.criteriaBuilder.in(path);
        for (Serializable conditionColumnValue : conditionColumnValues) {
            in.value(conditionColumnValue);
        }
        queryBuilder.criteriaQuery.where(in);

    }

According to ng-repeat docs http://docs.angularjs.org/api/ng.directive:ngRepeat, you can store the key or array index in the variable of your choice. (indexVar, valueVar) in values

so you can write

<div ng-repeat="(fIndex, f) in foos">
  <div>
    <div ng-repeat="b in foos.bars">
      <a ng-click="addSomething(fIndex)">Add Something</a>
    </div>
  </div>
</div>

One level up is still quite clean with $parent.$index but several parents up, things can get messy.

Note: $index will continue to be defined at each scope, it is not replaced by fIndex.

Add bottom:100% to your #menu:hover ul li:hover ul rule

Demo 1

#menu:hover ul li:hover ul {
    position: absolute;
    margin-top: 1px;
    font: 10px;
    bottom: 100%; /* added this attribute */
}

Or better yet to prevent the submenus from having the same effect, just add this rule

Demo 2

#menu>ul>li:hover>ul { 
    bottom:100%;
}

Demo 3

source: http://jsfiddle.net/W5FWW/4/

And to get back the border you can add the following attribute

#menu>ul>li:hover>ul { 
    bottom:100%;
    border-bottom: 1px solid transparent
}

Add two bindings to your website, one for local access and another for LAN access like so:

Open IIS and select your local website (that you want to access from your local network) from the left panel:

Connections > server (user-pc) > sites > local site

Open Bindings on the right panel under Actions tab add these bindings:

1. Local:

   Type: http
   Ip Address: All Unassigned
   Port: 80
   Host name: samplesite.local
   

2. LAN:

   Type: http
   Ip Address: <Network address of the hosting machine ex. 192.168.0.10>
   Port: 80
   Host name: <Leave it blank>
   

Voila, you should be able to access the website from any machine on your local network by using the host's LAN IP address (192.168.0.10 in the above example) as the site url.

NOTE:

if you want to access the website from LAN using a host name (like samplesite.local) instead of an ip address, add the host name to the hosts file on the local network machine (The hosts file can be found in "C:\Windows\System32\drivers\etc\hosts" in windows, or "/etc/hosts" in ubuntu):

192.168.0.10 samplesite.local

I was facing the similar error. It was solved when I did these three things:

1. Update to the latest rxjs:

   npm install rxjs@6 rxjs-compat@6 --save
   

2. Import map and promise:

   import 'rxjs/add/operator/map';
   import 'rxjs/add/operator/toPromise';
   

3. Added a new import statement:

   import { Observable, Subject, asapScheduler, pipe, of, from, interval, merge, fromEvent } from 'rxjs';
   

This method will convert a type of enum:

  public static TEnum ToEnum<TEnum>(object EnumValue, TEnum defaultValue)
    {
        if (!Enum.IsDefined(typeof(TEnum), EnumValue))
        {
            Type enumType = Enum.GetUnderlyingType(typeof(TEnum));
            if ( EnumValue.GetType() == enumType )
            {
                string name = Enum.GetName(typeof(HLink.ViewModels.ClaimHeaderViewModel.ClaimStatus), EnumValue);
                if( name != null)
                    return (TEnum)Enum.Parse(typeof(TEnum), name);
                return defaultValue;
            }
        }
        return (TEnum)Enum.Parse(typeof(TEnum), EnumValue.ToString());
    } 

It checks the underlying type and get the name against it to parse. If everything fails it will return default value.

Is there some kind of query language ...

jq defines a JSON query language that is very similar to JSONPath -- see https://github.com/stedolan/jq/wiki/For-JSONPath-users

... [which] I can used to find an item in [0].objects where id = 3?

I'll assume this means: find all JSON objects under the specified key with id == 3, no matter where the object may be. A corresponding jq query would be:

.[0].objects | .. | objects | select(.id==3)

where "|" is the pipe-operator (as in command shell pipes), and where the segment ".. | objects" corresponds to "no matter where the object may be".

The basics of jq are largely obvious or intuitive or at least quite simple, and most of the rest is easy to pick up if you're at all familiar with command-shell pipes. The jq FAQ has pointers to tutorials and the like.

jq is also like SQL in that it supports CRUD operations, though the jq processor never overwrites its input. jq can also handle streams of JSON entities.

Two other criteria you might wish to consider in assessing a JSON-oriented query language are:

• does it support regular expressions? (jq 1.5 has comprehensive support for PCRE regex)
• is it Turing-complete? (yep)

This should help you.

Dim Ws As Worksheet
Set Ws = Sheets("Sheet-Name")
Dim tbl As ListObject
Set tbl = Ws.ListObjects("Table-Name")

A probably convenient way to enter multi-line strings is by using macro's. This only works if quotes and parentheses are balanced and it does not contain 'top level' comma's:

#define MULTI_LINE_STRING(a) #a
const char *text = MULTI_LINE_STRING(
  Using this trick(,) you don't need to use quotes.
  Though newlines and     multiple     white   spaces
  will be replaced by a single whitespace.
);
printf("[[%s]]\n",text);

Compiled with gcc 4.6 or g++ 4.6, this produces: [[Using this trick(,) you don't need to use quotes. Though newlines and multiple white spaces will be replaced by a single whitespace.]]

Note that the , cannot be in the string, unless it is contained within parenthesis or quotes. Single quotes is possible, but creates compiler warnings.

Edit: As mentioned in the comments, #define MULTI_LINE_STRING(...) #__VA_ARGS__ allows the use of ,.

You should go for the simplest one (stringLength), readability always beats speed. But if you care about speed here are some below.

Three different methods all with varying speed.

// 34ms
let weissteinLength = function(n) { 
    return (Math.log(Math.abs(n)+1) * 0.43429448190325176 | 0) + 1;
}

// 350ms
let stringLength = function(n) {
    return n.toString().length;
}

// 58ms
let mathLength = function(n) {
    return Math.ceil(Math.log(n + 1) / Math.LN10);
}

// Simple tests below if you care about performance.

let iterations = 1000000;
let maxSize = 10000;

// ------ Weisstein length.

console.log("Starting weissteinLength length.");
let startTime = Date.now();

for (let index = 0; index < iterations; index++) {
    weissteinLength(Math.random() * maxSize);
}

console.log("Ended weissteinLength length. Took : " + (Date.now() - startTime ) + "ms");


// ------- String length slowest.

console.log("Starting string length.");
startTime = Date.now();

for (let index = 0; index < iterations; index++) {
    stringLength(Math.random() * maxSize);
}

console.log("Ended string length. Took : " + (Date.now() - startTime ) + "ms");


// ------- Math length.

console.log("Starting math length.");
startTime = Date.now();

for (let index = 0; index < iterations; index++) {
    mathLength(Math.random() * maxSize);
}

The simplest way in Python:

import time
start_time = time.time()
main()
print("--- %s seconds ---" % (time.time() - start_time))

This assumes that your program takes at least a tenth of second to run.

Prints:

--- 0.764891862869 seconds ---

I realize this has already been marked as answered, but we used to do it like this:

IF NOT EXISTS (SELECT * FROM sys.objects WHERE type = 'P' AND OBJECT_ID = OBJECT_ID('dbo.MyProc'))
   exec('CREATE PROCEDURE [dbo].[MyProc] AS BEGIN SET NOCOUNT ON; END')
GO

ALTER PROCEDURE [dbo].[MyProc] 
AS
  ....

Just to avoid dropping the procedure.

I like this format:

name     DataType      Collation             Constraints         PK  FK          Comment

id       int                                 NOT NULL IDENTITY   PK              Order Line Id
pid      int                                 NOT NULL                tbl_orders  Order Id
itemCode varchar(10)   Latin1_General_CI_AS  NOT NULL                            Product Code

So I have used this:

DECLARE @tname varchar(100) = 'yourTableName';

SELECT  col.name,

This problem may occur if you have two devices connected to the computer at the same time. Adb does not support reaching both devices via command/console. So, if you debug your app after connecting and disconnecting the second device you will most probably have this problem. One solution might be restarting adb and/or eclipse if necessary. It can be quite annoying sometimes and I am afraid there is no other solution to that.

My suggestion would be to get the book Programming From Ground Up:

http://nongnu.askapache.com/pgubook/ProgrammingGroundUp-1-0-booksize.pdf

That is a very good starting point for getting into assembler programming under linux and it explains a lot of the basics you need to understand to get started.

This should work:

SELECT YEAR(STR_TO_DATE(subdateshow, '%m/%d/%Y')) FROM table;

eg:

SELECT YEAR(STR_TO_DATE('01/17/2009', '%m/%d/%Y'));  /* shows "2009" */

If the size of the string is fixed, you might find easier to use an array of chars. If you have to do this a lot, it will be a tiny bit faster too.

char[] chars = new char[3];
chars[0] = 'i';
chars[1] = 'c';
chars[2] = 'e';
return new String(chars);

Also, I noticed in your original question, you use the Char class. If your chars are not nullable, it is better to use the lowercase char type.

Jquery 3.0 has some breaking changes that remove certain methods due to conflicts. Your error is most likely due to one of these changes such as the removal of the .load() event.

Read more in the jQuery Core 3.0 Upgrade Guide

To fix this you either need to rewrite the code to be compatible with Jquery 3.0 or else you can use the JQuery Migrate plugin which restores the deprecated and/or removed APIs and behaviours.

You can directly use

var message = $.trim($("#message").val());

Maven has updatePolicy settings for specifying the frequency to check the updates in the repository or to keep the repository in sync with remote.

• The default value for updatePolicy is daily.
• Other values can be always / never/ XX (specifying interval in minutes).

Below code sample can be added to maven user settings file to configure updatePolicy.

<pluginRepositories>
    <pluginRepository>
        <id>Releases</id>
        <url>http://<host>:<port>/nexus/content/repositories/releases/</url>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>daily</updatePolicy>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>             
</pluginRepositories>

Work for me :)

function jsonEncodeArray( $array ){
    array_walk_recursive( $array, function(&$item) { 
       $item = utf8_encode( $item ); 
    });
    return json_encode( $array );
}

Use the df command:

df -h

Use application/javascript as content type instead of text/javascript

text/javascript is mentioned obsolete. See reference docs.

http://www.iana.org/assignments/media-types/application

Also see this question on SO.

UPDATE:

I have tried executing the code you have given and the below didn't work.

res.setHeader('content-type', 'text/javascript');
res.send(JS_Script);

This is what worked for me.

res.setHeader('content-type', 'text/javascript');
res.end(JS_Script);

As robertklep has suggested, please refer to the node http docs, there is no response.send() there.

If you don't use prioritized tasks, this is actually pretty simple if you're using Redis. To get the task counts:

redis-cli -h HOST -p PORT -n DATABASE_NUMBER llen QUEUE_NAME

But, prioritized tasks use a different key in redis, so the full picture is slightly more complicated. The full picture is that you need to query redis for every priority of task. In python (and from the Flower project), this looks like:

PRIORITY_SEP = '\x06\x16'
DEFAULT_PRIORITY_STEPS = [0, 3, 6, 9]


def make_queue_name_for_pri(queue, pri):
    """Make a queue name for redis

    Celery uses PRIORITY_SEP to separate different priorities of tasks into
    different queues in Redis. Each queue-priority combination becomes a key in
    redis with names like:

     - batch1\x06\x163 <-- P3 queue named batch1

    There's more information about this in Github, but it doesn't look like it 
    will change any time soon:

      - https://github.com/celery/kombu/issues/422

    In that ticket the code below, from the Flower project, is referenced:

      - https://github.com/mher/flower/blob/master/flower/utils/broker.py#L135

    :param queue: The name of the queue to make a name for.
    :param pri: The priority to make a name with.
    :return: A name for the queue-priority pair.
    """
    if pri not in DEFAULT_PRIORITY_STEPS:
        raise ValueError('Priority not in priority steps')
    return '{0}{1}{2}'.format(*((queue, PRIORITY_SEP, pri) if pri else
                                (queue, '', '')))


def get_queue_length(queue_name='celery'):
    """Get the number of tasks in a celery queue.

    :param queue_name: The name of the queue you want to inspect.
    :return: the number of items in the queue.
    """
    priority_names = [make_queue_name_for_pri(queue_name, pri) for pri in
                      DEFAULT_PRIORITY_STEPS]
    r = redis.StrictRedis(
        host=settings.REDIS_HOST,
        port=settings.REDIS_PORT,
        db=settings.REDIS_DATABASES['CELERY'],
    )
    return sum([r.llen(x) for x in priority_names])

If you want to get an actual task, you can use something like:

redis-cli -h HOST -p PORT -n DATABASE_NUMBER lrange QUEUE_NAME 0 -1

From there you'll have to deserialize the returned list. In my case I was able to accomplish this with something like:

r = redis.StrictRedis(
    host=settings.REDIS_HOST,
    port=settings.REDIS_PORT,
    db=settings.REDIS_DATABASES['CELERY'],
)
l = r.lrange('celery', 0, -1)
pickle.loads(base64.decodestring(json.loads(l[0])['body']))

Just be warned that deserialization can take a moment, and you'll need to adjust the commands above to work with various priorities.

const static int newvals[] = {34,2,4,5,6};

std::copy(newvals, newvals+sizeof(newvals)/sizeof(newvals[0]), array);

    $("button").on("click",function(){
      //console.log("hii");
      $.ajax({
        headers:{  
           "key":"your key",
     "Accept":"application/json",//depends on your api
      "Content-type":"application/x-www-form-urlencoded"//depends on your api
        },   url:"url you need",
        success:function(response){
          var r=JSON.parse(response);
          $("#main").html(r.base);
        }
      });
});

After jQuery 1.7 the preferred methods are .on() and .off()

Sean's answer shows an example.

Now Deprecated:

Use the jQuery functions .live() and .die(). Available in jQuery 1.3.x

From the docs:

To display each paragraph's text in an alert box whenever it is clicked:

$("p").live("click", function(){
  alert( $(this).text() );
});

Also, the livequery plugin does this and has support for more events.

This can be caused by a vcxproj that originated in previous versions of Visual Studio OR changing the Platform Toolset in Configuration Properties -> General.

If so, possible Solution:

1) Go to Configuration Properties -> VC++ Directories

2) Select drop down for Executable Directories

3) Select "Inherit from parent or Project Defaults"

Previous answers can be improved in terms of performances and compatibility.

Check once if the Error object exists, if not declare it :

if (typeof Error === "undefined") {
    Error = function(message) {
        this.message = message;
    };
    Error.prototype.message = "";
}

Then, each assertion will check the condition, and always throw an Error object

function assert(condition, message) {
    if (!condition) throw new Error(message || "Assertion failed");
}

Keep in mind that the console will not display the real error line number, but the line of the assert function, which is not useful for debugging.

Current best practice (tidyverse) is:

require(dplyr)
df1 %>% count(Year, Month)

It's not possible to do it just like that, but you can overlay an opaque div between the div with the background-image and the text and fade that one out, hence giving the appearance that the background is fading in.

You need to set map null to that marker.

var markersList = [];    

function removeMarkers(markersList) {
   for(var i = 0; i < markersList.length; i++) {
      markersList[i].setMap(null);
   }
}

function addMarkers() {
   var marker = new google.maps.Marker({
        position : {
            lat : 12.374,
            lng : -11.55
        },
        map : map
       });
      markersList.push(marker);
   }

I don't understand what exactly is the problem with implementing location listening functionality in the Service. It looks pretty similar to what you do in Activity. Just define a location listener and register for location updates. You can refer to the following code as example:

Manifest file:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<application
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name" >
    <activity android:label="@string/app_name" android:name=".LocationCheckerActivity" >
        <intent-filter >
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <service android:name=".MyService" android:process=":my_service" />
</application>

The service file:

import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.location.Location;
import android.location.LocationManager;
import android.os.Bundle;
import android.os.IBinder;
import android.util.Log;

public class MyService extends Service {

    private static final String TAG = "BOOMBOOMTESTGPS";
    private LocationManager mLocationManager = null;
    private static final int LOCATION_INTERVAL = 1000;
    private static final float LOCATION_DISTANCE = 10f;

    private class LocationListener implements android.location.LocationListener {
        Location mLastLocation;

        public LocationListener(String provider) {
            Log.e(TAG, "LocationListener " + provider);
            mLastLocation = new Location(provider);
        }

        @Override
        public void onLocationChanged(Location location) {
            Log.e(TAG, "onLocationChanged: " + location);
            mLastLocation.set(location);
        }

        @Override
        public void onProviderDisabled(String provider) {
            Log.e(TAG, "onProviderDisabled: " + provider);
        }

        @Override
        public void onProviderEnabled(String provider) {

    LocationListener[] mLocationListeners = new LocationListener[]{
            new LocationListener(LocationManager.GPS_PROVIDER),
            new LocationListener(LocationManager.NETWORK_PROVIDER)
    };

    @Override
    public IBinder onBind(Intent arg0) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.e(TAG, "onStartCommand");
        super.onStartCommand(intent, flags, startId);
        return START_STICKY;
    }

    @Override
    public void onCreate() {
        Log.e(TAG, "onCreate");
        initializeLocationManager();
        try {
            mLocationManager.requestLocationUpdates(
                    LocationManager.NETWORK_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
                    mLocationListeners[1]);
        } catch (java.lang.SecurityException ex) {
            Log.i(TAG, "fail to request location update, ignore", ex);
        } catch (IllegalArgumentException ex) {
            Log.d(TAG, "network provider does not exist, " + ex.getMessage());
        }
        try {
            mLocationManager.requestLocationUpdates(
                    LocationManager.GPS_PROVIDER, LOCATION_INTERVAL, LOCATION_DISTANCE,
                    mLocationListeners[0]);
        } catch (java.lang.SecurityException ex) {
            Log.i(TAG, "fail to request location update, ignore", ex);
        } catch (IllegalArgumentException ex) {
            Log.d(TAG, "gps provider does not exist " + ex.getMessage());
        }
    }

    @Override
    public void onDestroy() {
        Log.e(TAG, "onDestroy");
        super.onDestroy();
        if (mLocationManager != null) {
            for (int i = 0; i < mLocationListeners.length; i++) {
                try {
                    mLocationManager.removeUpdates(mLocationListeners[i]);
                } catch (Exception ex) {
                    Log.i(TAG, "fail to remove location listners, ignore", ex);
                }
            }
        }
    }

    private void initializeLocationManager() {
        Log.e(TAG, "initializeLocationManager");
        if (mLocationManager == null) {
            mLocationManager = (LocationManager) getApplicationContext().getSystemService(Context.LOCATION_SERVICE);
        }

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

Explanation

s[i:j:k] is, according to the documentation, "slice of s from i to j with step k". When i and j are absent, the whole sequence is assumed and thus s[::k] means "every k-th item".

Examples

First, let's initialize a list:

>>> s = range(20)
>>> s
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]

Let's take every 3^rd item from s:

>>> s[::3]
[0, 3, 6, 9, 12, 15, 18]

Let's take every 3^rd item from s[2:]:

>>> s[2:]
[2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19]
>>> s[2::3]
[2, 5, 8, 11, 14, 17]

Let's take every 3^rd item from s[5:12]:

>>> s[5:12]
[5, 6, 7, 8, 9, 10, 11]
>>> s[5:12:3]
[5, 8, 11]

Let's take every 3^rd item from s[:10]:

>>> s[:10]
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
>>> s[:10:3]
[0, 3, 6, 9]

We can use LIMIT like bellow:

Model::take(20)->get();

You can use the variables name itself to check if a value is an integer. for example:

#include <iostream>
using namespace std;

int main (){

int firstvariable;
int secondvariable;
float float1;
float float2;

cout << "Please enter two integers and then press Enter:" << endl;
cin >> firstvariable;
cin >> secondvariable;

if(firstvariable && secondvariable){
    cout << "Time for some simple mathematical operations:\n" << endl;

    cout << "The sum:\n " << firstvariable << "+" << secondvariable 
    <<"="<< firstvariable + secondvariable << "\n " << endl;
}else{
    cout << "\n[ERROR\tINVALID INPUT]\n"; 
    return 1; 
} 
return 0;    
}

As of August 2020, Google Play's In-App Review API is available and its straightforward implementation is correct as per this answer.

But if you wish add some display logic on top of it, use the Five-Star-Me library.

Set launch times and install days in the onCreate method of the MainActivity to configure the library.

  FiveStarMe.with(this)
      .setInstallDays(0) // default 10, 0 means install day.
      .setLaunchTimes(3) // default 10
      .setDebug(false) // default false
      .monitor();

Then place the below method call on any activity / fragment's onCreate / onViewCreated method to show the prompt whenever the conditions are met.

FiveStarMe.showRateDialogIfMeetsConditions(this); //Where *this* is the current activity.

Installation instructions:

You can download from jitpack.

Step 1: Add this to project (root) build.gradle.

allprojects {
  repositories {
    ...
    maven { url 'https://jitpack.io' }
  }
}

Step 2: Add the following dependency to your module (app) level build.gradle.

dependencies {
  implementation 'com.github.numerative:Five-Star-Me:2.0.0'
}

Since many people arrive here debugging their slow website I would like to inform you about my case which none of the google explanations helped to resolve. My huge stalled times (sometimes 1min) were caused by Apache running on Windows having too few worker threads to handle the connections, therefore they were being queued.

This may apply to you if you apache log has following note:

Server ran out of threads to serve requests. Consider raising the ThreadsPerChild setting

This issue is resolved in Apache httpd.conf. Uncomment : Include conf/extra/httpd-mpm.conf

And edit httpd-mpm.conf

<IfModule mpm_winnt_module>
   ThreadLimit              2000
   ThreadsPerChild          2000
   MaxConnectionsPerChild   0
</IfModule>

Note that you may not need 2000 threads, or may need more. 2000 was OK for my case.

git config user.email "[email protected]"

Doing that one inside a repo will set the configuration on THAT repo, and not globally.

Seems like that's pretty much what you're after, unless I'm misreading you.

You might try a lazy unmount:

umount -l

If you are in Windows, please select "run as administrator" for the command prompt for executing the java app (ie: for executing java -jar ${your_jar_path}\lombok-1.14.6.jar).

You need to wrap this in script tags:

<script type='text/javascript'> ... your code ... </script>

That being said, it's important WHEN you execute this code. If you put this in the page BEFORE the HTML elements that it is hooking into then the script will run BEFORE the HTML is actually rendered in the page, so it will fail.

It is common practice to wrap this type of code in a "document ready" block, like so:

<script type='text/javascript'>
$(document).ready(function() {

... your code...

}}
</script>

This ensures that the entire page has rendered in the browser BEFORE your code is executed. It is also a best practice to put the code in the <head> section of your page.

If you set the span to display: inline-block, automatic horizontal and vertical resizing works very well:

<span contenteditable="true" _x000D_
      style="display: inline-block;_x000D_
             border: solid 1px black;_x000D_
             min-width: 50px; _x000D_
             max-width: 200px">_x000D_
</span>

If you want to get which column values are different, you could use Entity-Attribute-Value model:

declare @Data1 xml, @Data2 xml

select @Data1 = 
(
    select * 
    from (select * from Test1 except select * from Test2) as a
    for xml raw('Data')
)

select @Data2 = 
(
    select * 
    from (select * from Test2 except select * from Test1) as a
    for xml raw('Data')
)

;with CTE1 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data1.nodes('Data/@*') as T(C)    
), CTE2 as (
    select
        T.C.value('../@ID', 'bigint') as ID,
        T.C.value('local-name(.)', 'nvarchar(128)') as Name,
        T.C.value('.', 'nvarchar(max)') as Value
    from @Data2.nodes('Data/@*') as T(C)     
)
select
    isnull(C1.ID, C2.ID) as ID, isnull(C1.Name, C2.Name) as Name, C1.Value as Value1, C2.Value as Value2
from CTE1 as C1
    full outer join CTE2 as C2 on C2.ID = C1.ID and C2.Name = C1.Name
where
not

For Windows...in order to make gradle re-download specific dependencies:

1. delete the dependencies you want to re-download from the directory below:

   C:\Users\%USERNAME%\.gradle\caches\modules-2\files-2.1
   

2. delete all metadata directories at the path:

   C:\Users\%USERNAME%\.gradle\caches\modules-2\metadata-*
   

3. run gradle build (or gradlew build if using gradle wrapper) in the project's root directory.

If I understand the question correctly, it has to do with output buffering and the affect this might have on closing/ending tags. I am not sure that is an entirely valid question. The problem is that the output buffer does not mean all content is held in memory before sending it out to the client. It means some of the content is.

The programmer can purposely flush the buffer, or the output buffer so does the output buffer option in PHP really change how the closing tag affects coding? I would argue that it does not.

And maybe that is why most of the answers went back to personal style and syntax.

This only works when your TextView has the focus.

Points to keep in mind:

1. Pointers can be NULL, references cannot be NULL.

2. References are easier to use, const can be used for a reference when we don't want to change value and just need a reference in a function.

3. Pointer used with a * while references used with a &.

4. Use pointers when pointer arithmetic operation are required.

5. You can have pointers to a void type int a=5; void *p = &a; but cannot have a reference to a void type.

Pointer Vs Reference

void fun(int *a)
{
    cout<<a<<'\n'; // address of a = 0x7fff79f83eac
    cout<<*a<<'\n'; // value at a = 5
    cout<<a+1<<'\n'; // address of a increment by 4 bytes(int) = 0x7fff79f83eb0
    cout<<*(a+1)<<'\n'; // value here is by default = 0
}
void fun(int &a)
{
    cout<<a<<'\n'; // reference of original a passed a = 5
}
int a=5;
fun(&a);
fun(a);

Verdict when to use what

Pointer: For array, linklist, tree implementations and pointer arithmetic.

Reference: In function parameters and return types.

If you are using functional components in React

const [cars, setCars] = useState([{
  name: 'Audi',
  type: 'sedan'
}, {
  name: 'BMW',
  type: 'sedan'
}])

...

const newCar = {
  name: 'Benz',
  type: 'sedan'
}

const updatedCarsArray = [...cars, newCar];

setCars(updatedCarsArray);

1:

what are the Grant Tables?

from dev.mysql.com

The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.

clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables

2:

note that if you perform:

UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';

and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:

mysql -u someuser -p

your access will be denied by your new password until you perform :

FLUSH PRIVILEGES;

The translation is correct, the typing of the expression isn't. TypeScript is incorrectly typing the expression new Thing[100] as an array. It should be an error to index Thing, a constructor function, using the index operator. In C# this would allocate an array of 100 elements. In JavaScript this calls the value at index 100 of Thing as if was a constructor. Since that values is undefined it raises the error you mentioned. In JavaScript and TypeScript you want new Array(100) instead.

You should report this as a bug on CodePlex.

There's no real danger in not freeing your variables, but if you assign a pointer to a block of memory to a different block of memory without freeing the first block, the first block is no longer accessible but still takes up space. This is what's called a memory leak, and if you do this with regularity then your process will start to consume more and more memory, taking away system resources from other processes.

If the process is short-lived you can often get away with doing this as all allocated memory is reclaimed by the operating system when the process completes, but I would advise getting in the habit of freeing all memory you have no further use for.

In vb.net or C# I would expect that the fastest general approach to compare a variable against any reasonable number of separately-named objects (as opposed to e.g. all the things in a collection) will be to simply compare each object against the comparand much as you have done. It is certainly possible to create an instance of a collection and see if it contains the object, and doing so may be more expressive than comparing the object against all items individually, but unless one uses a construct which the compiler can explicitly recognize, such code will almost certainly be much slower than simply doing the individual comparisons. I wouldn't worry about speed if the code will by its nature run at most a few hundred times per second, but I'd be wary of the code being repurposed to something that's run much more often than originally intended.

An alternative approach, if a variable is something like an enumeration type, is to choose power-of-two enumeration values to permit the use of bitmasks. If the enumeration type has 32 or fewer valid values (e.g. starting Harry=1, Ron=2, Hermione=4, Ginny=8, Neville=16) one could store them in an integer and check for multiple bits at once in a single operation ((if ((thisOne & (Harry | Ron | Neville | Beatrix)) != 0) /* Do something */. This will allow for fast code, but is limited to enumerations with a small number of values.

A somewhat more powerful approach, but one which must be used with care, is to use some bits of the value to indicate attributes of something, while other bits identify the item. For example, bit 30 could indicate that a character is male, bit 29 could indicate friend-of-Harry, etc. while the lower bits distinguish between characters. This approach would allow for adding characters who may or may not be friend-of-Harry, without requiring the code that checks for friend-of-Harry to change. One caveat with doing this is that one must distinguish between enumeration constants that are used to SET an enumeration value, and those used to TEST it. For example, to set a variable to indicate Harry, one might want to set it to 0x60000001, but to see if a variable IS Harry, one should bit-test it with 0x00000001.

One more approach, which may be useful if the total number of possible values is moderate (e.g. 16-16,000 or so) is to have an array of flags associated with each value. One could then code something like "if (((characterAttributes[theCharacter] & chracterAttribute.Male) != 0)". This approach will work best when the number of characters is fairly small. If array is too large, cache misses may slow down the code to the point that testing against a small number of characters individually would be faster.

{ name: 'book', tags: { words: ['abc','123'], lat: 33, long: 22 } }

Ans:

db.tablename.remove({'tags.words':['abc','123']})

A better way to debug the code is, by using module clrprint

It prints a color full output only when pass parameter debug=True

from clrprint import *
clrprint('ERROR:', information,clr=['r','y'], debug=True)

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 = ","

Enabled="false" in aspx page

You can try below code will preserve any white-space and new lines in your text.

$str = "
put returns between paragraphs

for linebreak add 2 spaces at end

";

echo preg_replace( "/\r|\n/", "", $str );

Here's another easy way to do

char str[100];
sprintf(str, "%d", 101);
string s = str;

sprintf is a well-known one to insert any data into a string of the required format.

You can convert a char * array to a string as shown in the third line.

perl:

perl -lane 'print join(' ',@F[2..$#F])' File

awk:

awk '{$1=$2=""}1' File

 <script type="text/javascript">
      var multilinestr = `
        line 1
        line 2
        line 3
        line 4
        line 5
        line 6`;
      totallines = multilinestr.split("\n");
lines = str.split("\n"); 
console.log(lines.length);
</script>

thats works in my case

This Works

function saveBase64AsFile(base64, fileName) {
    var link = document.createElement("a");
    document.body.appendChild(link);
    link.setAttribute("type", "hidden");
    link.href = "data:text/plain;base64," + base64;
    link.download = fileName;
    link.click();  
    document.body.removeChild(link);
}

Based on the answer above but with some changes

Let me explain with an example and you would be able to see how it works.

Assuming you have the following table DIM_EQUIPMENT:

VIN         MAKE    MODEL   YEAR    COLOR
-----------------------------------------
1234ASDF    Ford    Taurus  2008    White
1234JKLM    Chevy   Truck   2005    Green
5678ASDF    Ford    Mustang 2008    Yellow

Run below SQL

SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR ,
  COUNT(*) OVER (PARTITION BY YEAR) AS COUNT2
FROM DIM_EQUIPMENT

The result would be as below

VIN         MAKE    MODEL   YEAR    COLOR     COUNT2
 ----------------------------------------------  
1234JKLM    Chevy   Truck   2005    Green     1
5678ASDF    Ford    Mustang 2008    Yellow    2
1234ASDF    Ford    Taurus  2008    White     2

See what happened.

You are able to count without Group By on YEAR and Match with ROW.

Another Interesting WAY to get same result if as below using WITH Clause, WITH works as in-line VIEW and can simplify the query especially complex ones, which is not the case here though since I am just trying to show usage

 WITH EQ AS
  ( SELECT YEAR AS YEAR2, COUNT(*) AS COUNT2 FROM DIM_EQUIPMENT GROUP BY YEAR
  )
SELECT VIN,
  MAKE,
  MODEL,
  YEAR,
  COLOR,
  COUNT2
FROM DIM_EQUIPMENT,
  EQ
WHERE EQ.YEAR2=DIM_EQUIPMENT.YEAR;

I got a solution:

b) Example local Image:

The of(E... elements) method in Java9 can be used to create immutable list using just a line:

List<Integer> items = List.of(1,2,3,4,5);

The above method returns an immutable list containing an arbitrary number of elements. And adding any integer to this list would result in java.lang.UnsupportedOperationExceptionexception. This method also accepts a single array as an argument.

String[] array = ... ;
List<String[]> list = List.<String[]>of(array);

You may just remove all spaces and leverage LINQ All:

Determines whether all elements of a sequence satisfy a condition.

Use it as shown below:

Dim number As String = "077 234 211"
If number.Replace(" ", "").All(AddressOf Char.IsDigit) Then
    Console.WriteLine("The string is all numeric (spaces ignored)!")
Else
    Console.WriteLine("The string contains a char that is not numeric and space!")
End If

To only check if a string consists of only digits use:

If number.All(AddressOf Char.IsDigit) Then

console.log(Math.floor(100000 + Math.random() * 900000));

Will always create a number of 6 digits and it ensures the first digit will never be 0. The code in your question will create a number of less than 6 digits.

I am doing similar thing to compile all the c files in a directory.
for iterating files in different directory try this.

set codedirectory=C:\Users\code
for /r  %codedirectory% %%i in (*.c) do 
( some GCC commands )

try this:

<div ng-if="$scope.length == 0" ? true : false></div>

and show or hide

<div ng-show="$scope.length == 0"></div>

else it will be hide

-----------------or--------------------------

if you are using $ctrl than code will be like this:

try this:

<div ng-if="$ctrl.length == 0" ? true : false></div>

and show or hide

<div ng-show="$ctrl.length == 0"></div>

else it will be hide

Strings have helper functions and manage char arrays automatically. You can concatenate strings, for a char array you would need to copy it to a new array, strings can change their length at runtime. A char array is harder to manage than a string and certain functions may only accept a string as input, requiring you to convert the array to a string. It's better to use strings, they were made so that you don't have to use arrays. If arrays were objectively better we wouldn't have strings.

As always with these questions, the JLS holds the answer. In this case §15.26.2 Compound Assignment Operators. An extract:

A compound assignment expression of the form E1 op= E2 is equivalent to E1 = (T)((E1) op (E2)), where T is the type of E1, except that E1 is evaluated only once.

An example cited from §15.26.2

[...] the following code is correct:

short x = 3;
x += 4.6;

and results in x having the value 7 because it is equivalent to:

short x = 3;
x = (short)(x + 4.6);

In other words, your assumption is correct.

I had an issue with XCode 10.2 specifying the correct iOS simulator version number, so used:

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

This comment syntax should work for you:

@* enter comments here *@

a.h:

#ifndef A_H
#define A_H

struct a { 
    int i;
    struct b {
        int j;
    }
};

#endif

there you go, now you just need to include a.h to the files where you want to use this structure.

EDIT Summary and reccomendations

Using a for each cell in range construct is not in itself slow. What is slow is repeated access to Excel in the loop (be it reading or writing cell values, format etc, inserting/deleting rows etc).

What is too slow depends entierly on your needs. A Sub that takes minutes to run might be OK if only used rarely, but another that takes 10s might be too slow if run frequently.

So, some general advice:

1. keep it simple at first. If the result is too slow for your needs, then optimise
2. focus on optimisation of the content of the loop
3. don't just assume a loop is needed. There are sometime alternatives
4. if you need to use cell values (a lot) inside the loop, load them into a variant array outside the loop.
5. a good way to avoid complexity with inserts is to loop the range from the bottom up
   (for index = max to min step -1)
6. if you can't do that and your 'insert a row here and there' is not too many, consider reloading the array after each insert
7. If you need to access cell properties other than value, you are stuck with cell references
8. To delete a number of rows consider building a range reference to a multi area range in the loop, then delete that range in one go after the loop

eg (not tested!)

Dim rngToDelete as range
for each rw in rng.rows
    if need to delete rw then

        if rngToDelete is nothing then
            set rngToDelete = rw
        else
            set rngToDelete = Union(rngToDelete, rw)
        end if

    endif
next
rngToDelete.EntireRow.Delete

Original post

Conventional wisdom says that looping through cells is bad and looping through a variant array is good. I too have been an advocate of this for some time. Your question got me thinking, so I did some short tests with suprising (to me anyway) results:

test data set: a simple list in cells A1 .. A1000000 (thats 1,000,000 rows)

Test case 1: loop an array

Dim v As Variant
Dim n As Long

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    'i = i + 1
    'i = r.Cells(n, 1).Value 'i + 1
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Array Count = " & Format(n, "#,###")

Result:

Array Time = 0.249 sec
Array Count = 1,000,001

Test Case 2: loop the range

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000#
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 0.296 sec
Range Count = 1,000,000

So,looping an array is faster but only by 19% - much less than I expected.

Test 3: loop an array with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
v = r
For n = LBound(v, 1) To UBound(v, 1)
    i = r.Cells(n, 1).Value
Next
Debug.Print "Array Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Array Count = " & Format(i, "#,###")

Result:

Array Time = 5.897 sec
Array Count = 1,000,000

Test case 4: loop range with a cell reference

T1 = GetTickCount
Set r = Range("$A$1", Cells(Rows.Count, "A").End(xlUp)).Cells
For Each c In r
    i = c.Value
Next c
Debug.Print "Range Time = " & (GetTickCount - T1) / 1000# & " sec"
Debug.Print "Range Count = " & Format(r.Cells.Count, "#,###")

Result:

Range Time = 2.356 sec
Range Count = 1,000,000

So event with a single simple cell reference, the loop is an order of magnitude slower, and whats more, the range loop is twice as fast!

So, conclusion is what matters most is what you do inside the loop, and if speed really matters, test all the options

FWIW, tested on Excel 2010 32 bit, Win7 64 bit All tests with

• ScreenUpdating off,
• Calulation manual,
• Events disabled.

For all those stuck with a similar problem, run the following:

LD_LIBRARY_PATH=/usr/local/lib64/:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH

When you compile and install GCC it does put the libraries here but that's it. As the FAQs say ( http://gcc.gnu.org/onlinedocs/libstdc++/faq.html#faq.how_to_set_paths ) you need to add it.

I assumed "How do I insure that the dynamically linked library will be found? " meant "how do I make sure it is always found" not "it wont be found, you need to do this"

For those who don't bother setting a prefix, it is /usr/local/lib64

You can find this mentioned briefly when you install gcc if you read the make output:

Libraries have been installed in:
   /usr/local/lib/../lib32
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages. 

Grr that was simple! Also "if you ever happen to want to link against the installed libraries" - seriously?

A shorter answer from here, adapted to this question:

var arr = $('.requiredText');
arr.each(function(index, item) {
   var is_last_item = (index == (arr.length - 1));
});

Just for completeness.

apply takes a function to apply to each value, not the series, and accepts kwargs. So, the values do not have the .size() method.

Perhaps this would work:

from pandas import *

d = {"my_label": Series(['A','B','A','C','D','D','E'])}
df = DataFrame(d)


def as_perc(value, total):
    return value/float(total)

def get_count(values):
    return len(values)

grouped_count = df.groupby("my_label").my_label.agg(get_count)
data = grouped_count.apply(as_perc, total=df.my_label.count())

The .agg() method here takes a function that is applied to all values of the groupby object.

count($Contents);

or

sizeof($Contents);

It looks like ByRef needs to know the size of the parameter. A declaration of Dim last_name as string doesn't specify the size of the string so it takes it as an error. Before using Worksheets(data_sheet).Range("C2").Value = ProcessString(last_name) The last_name has to be declared as Dim last_name as string *10 ' size of string is up to you but must be a fix length

No need to change the function. Function doesn't take a fix length declaration.

I had a similar problem that I resolved myself.... I think it was partially my code hogging too much memory while too many "big things"

in my application - the workbook goes out and grabs another departments "daily report".. and I extract out all the information our team needs (to minimize mistakes and data entry).

I pull in their sheets directly... but I hate the fact that they use Merged cells... which I get rid of (ie unmerge, then find the resulting blank cells, and fill with the values from above)

I made my problem go away by

a)unmerging only the "used cells" - rather than merely attempting to do entire column... ie finding the last used row in the column, and unmerging only this range (there is literally 1000s of rows on each of the sheet I grab)

b) Knowing that the undo only looks after the last ~16 events... between each "unmerge" - i put 15 events which clear out what is stored in the "undo" to minimize the amount of memory held up (ie go to some cell with data in it.. and copy// paste special value... I was GUESSING that the accumulated sum of 30sheets each with 3 columns worth of data might be taxing memory set as side for undoing

Yes it doesn't allow for any chance of an Undo... but the entire purpose is to purge the old information and pull in the new time sensitive data for analysis so it wasn't an issue

Sound corny - but my problem went away

Using generator expressions to create a sequence of all primes and slice the 100th out of that.

from itertools import count, islice
primes = (n for n in count(2) if all(n % d for d in range(2, n)))
print("100th prime is %d" % next(islice(primes, 99, 100)))

I usually use:

l = [ word.strip() for word in text.split(',') ]

the strip remove spaces around words.

Giving an element the attribute readonly will give that element the readonly status. It doesn't matter what value you put after it or if you put any value after it, it will still see it as readonly. Putting readonly="false" won't work.

Suggested is to use the W3C standard, which is readonly="readonly".

Nothing works from this tread. "forRoot" doesn't help.

Sorry. Sorted this out. I've managed to make it work by setting correct "routes" for this "forRoot" router setup routine

    import {RouterModule, Routes} from '@angular/router';    
    import {AppComponent} from './app.component';
    
    const appRoutes: Routes = [
      {path: 'UI/part1/Details', component: DetailsComponent}
    ];
    
    @NgModule({
      declarations: [
        AppComponent,
        DetailsComponent
      ],
      imports: [
        BrowserModule,
        HttpClientModule,
        RouterModule.forRoot(appRoutes)
      ],
      providers: [DetailsService],
      bootstrap: [AppComponent]
    })

Also may be helpful (spent some time to realize this) Optional route part:

    const appRoutes: Routes = [
       {path: 'UI/part1/Details', component: DetailsComponent},
       {path: ':project/UI/part1/Details', component: DetailsComponent}
    ];

Second rule allows to open URLs like
hostname/test/UI/part1/Details?id=666
and
hostname/UI/part1/Details?id=666

Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2 (I have 3 years experience with enterprise level ExtJS)

jQuery offers $.inArray:

Note that inArray returns the index of the element found, so 0 indicates the element is the first in the array. -1 indicates the element was not found.

var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = $.inArray('specialword', categoriesPresent) > -1;_x000D_
var foundNotPresent = $.inArray('specialword', categoriesNotPresent) > -1;_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Edit 3.5 years later

$.inArray is effectively a wrapper for Array.prototype.indexOf in browsers that support it (almost all of them these days), while providing a shim in those that don't. It is essentially equivalent to adding a shim to Array.prototype, which is a more idiomatic/JSish way of doing things. MDN provides such code. These days I would take this option, rather than using the jQuery wrapper.

var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = categoriesPresent.indexOf('specialword') > -1;_x000D_
var foundNotPresent = categoriesNotPresent.indexOf('specialword') > -1;_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false

Edit another 3 years later

_{Gosh, 6.5 years?!}

The best option for this in modern Javascript is Array.prototype.includes:

var found = categories.includes('specialword');

No comparisons and no confusing -1 results. It does what we want: it returns true or false. For older browsers it's polyfillable using the code at MDN.

var categoriesPresent = ['word', 'word', 'specialword', 'word'];_x000D_
var categoriesNotPresent = ['word', 'word', 'word'];_x000D_
_x000D_
var foundPresent = categoriesPresent.includes('specialword');_x000D_
var foundNotPresent = categoriesNotPresent.includes('specialword');_x000D_
_x000D_
console.log(foundPresent, foundNotPresent); // true false

By using EntityManager, code is no longer tightly coupled with hibernate. But for this, in usage we should use :

javax.persistence.EntityManager

instead of

org.hibernate.ejb.HibernateEntityManager

Similarly, for EntityManagerFactory, use javax interface. That way, the code is loosely coupled. If there is a better JPA 2 implementation than hibernate, switching would be easy. In extreme case, we could type cast to HibernateEntityManager.

Wouldn't it be more pythonic to use slicing?

For example, to pad a string with spaces on the right until it's 10 characters long:

>>> x = "string"    
>>> (x + " " * 10)[:10]   
'string    '

To pad it with spaces on the left until it's 15 characters long:

>>> (" " * 15 + x)[-15:]
'         string'

It requires knowing how long you want to pad to, of course, but it doesn't require measuring the length of the string you're starting with.

To remove the scrollbar add the following CSS:

select[multiple] {
    overflow-y: auto;
}

Here's a snippet:

select[multiple] {_x000D_
  overflow-y: auto;_x000D_
}

<select>_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>_x000D_
_x000D_
<select multiple size="3">_x000D_
  <option value="1">One</option>_x000D_
  <option value="2">Two</option>_x000D_
  <option value="3">Three</option>_x000D_
</select>

Prior to C++11, you cannot initialise an array using type[]. However the latest c++11 provides(unifies) the initialisation, so you can do it in this way:

string* pStr = new string[3] { "hi", "there"};

See http://www2.research.att.com/~bs/C++0xFAQ.html#uniform-init

This msdn article explains it very well with examples, "A tuple is a data structure that has a specific number and sequence of elements".

Tuples are commonly used in four ways:

1. To represent a single set of data. For example, a tuple can represent a database record, and its components can represent individual fields of the record.

2. To provide easy access to, and manipulation of, a data set.

3. To return multiple values from a method without using out parameters (in C#) or ByRef parameters (in Visual Basic).

4. To pass multiple values to a method through a single parameter. For example, the Thread.Start(Object) method has a single parameter that lets you supply one value to the method that the thread executes at startup time. If you supply a Tuple<T1, T2, T3> object as the method argument, you can supply the thread’s startup routine with three items of data.

Try this if you don't want to use the UDF function.

SELECT COLUMN1, TRY_CONVERT(xml, COLUMN2).value('.', 'nvarchar(max)') as COL2, COLUMN3
FROM   DBO.TABLENAME        

Here is the C++ implementation of Jon Skeets Answer. It might not be the most optimal way of implementing it, but it does exactly what it's supposed to.

class Stack {
private:
    struct stack_node {
        int val;
        stack_node *next;
    };
    stack_node *top;
    stack_node *min_top;
public:
    Stack() {
        top = nullptr;
        min_top = nullptr;
    }    
    void push(int num) {
        stack_node *new_node = nullptr;
        new_node = new stack_node;
        new_node->val = num;

        if (is_empty()) {
            top = new_node;
            new_node->next = nullptr;

            min_top = new_node;
            new_node->next = nullptr;
        } else {
            new_node->next = top;
            top = new_node;

            if (new_node->val <= min_top->val) {
                new_node->next = min_top;
                min_top = new_node;
            }
        }
    }

    void pop(int &num) {
        stack_node *tmp_node = nullptr;
        stack_node *min_tmp = nullptr;

        if (is_empty()) {
            std::cout << "It's empty\n";
        } else {
            num = top->val;
            if (top->val == min_top->val) {
                min_tmp = min_top->next;
                delete min_top;
                min_top = min_tmp;
            }
            tmp_node = top->next;
            delete top;
            top = tmp_node;
        }
    }

    bool is_empty() const {
        return !top;
    }

    void get_min(int &item) {
        item = min_top->val;
    }
};

And here is the driver for the class

int main() {
    int pop, min_el;
    Stack my_stack;

    my_stack.push(4);
    my_stack.push(6);
    my_stack.push(88);
    my_stack.push(1);
    my_stack.push(234);
    my_stack.push(2);

    my_stack.get_min(min_el);
    cout << "Min: " << min_el << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.pop(pop);
    cout << "Popped stock element: " << pop << endl;

    my_stack.get_min(min_el);
    cout << "Min: " << min_el << endl;

    return 0;
}

Output:

Min: 1
Popped stock element: 2
Popped stock element: 234
Popped stock element: 1
Min: 4

Just a note for reference: I was trying to do shorthand like so:

background: url('../images/sprite.png') -312px -234px / 355px auto no-repeat;

but iPhone Safari browsers weren't showing the image properly with a fixed position element. I didn't check with a non-fixed, because I'm lazy. I had to switch the css to what's below, being careful to put background-size after the background property. If you do them in reverse, the background reverts the background-size to the original size of the image. So generally I would avoid using the shorthand to set background-size.

background: url('../images/sprite.png') -312px -234px no-repeat;
background-size: 355px auto;

Slicing data with pandas

Given a dataframe like this:

    RPT_Date  STK_ID STK_Name  sales
0 1980-01-01       0   Arthur      0
1 1980-01-02       1    Beate      4
2 1980-01-03       2    Cecil      2
3 1980-01-04       3     Dana      8
4 1980-01-05       4     Eric      4
5 1980-01-06       5    Fidel      5
6 1980-01-07       6   George      4
7 1980-01-08       7     Hans      7
8 1980-01-09       8   Ingrid      7
9 1980-01-10       9    Jones      4

There are multiple ways of selecting or slicing the data.

Using .isin

The most obvious is the .isin feature. You can create a mask that gives you a series of True/False statements, which can be applied to a dataframe like this:

mask = df['STK_ID'].isin([4, 2, 6])

mask
0    False
1    False
2     True
3    False
4     True
5    False
6     True
7    False
8    False
9    False
Name: STK_ID, dtype: bool

df[mask]
    RPT_Date  STK_ID STK_Name  sales
2 1980-01-03       2    Cecil      2
4 1980-01-05       4     Eric      4
6 1980-01-07       6   George      4

Masking is the ad-hoc solution to the problem, but does not always perform well in terms of speed and memory.

With indexing

By setting the index to the STK_ID column, we can use the pandas builtin slicing object .loc

df.set_index('STK_ID', inplace=True)
         RPT_Date STK_Name  sales
STK_ID                           
0      1980-01-01   Arthur      0
1      1980-01-02    Beate      4
2      1980-01-03    Cecil      2
3      1980-01-04     Dana      8
4      1980-01-05     Eric      4
5      1980-01-06    Fidel      5
6      1980-01-07   George      4
7      1980-01-08     Hans      7
8      1980-01-09   Ingrid      7
9      1980-01-10    Jones      4

df.loc[[4, 2, 6]]
         RPT_Date STK_Name  sales
STK_ID                           
4      1980-01-05     Eric      4
2      1980-01-03    Cecil      2
6      1980-01-07   George      4

This is the fast way of doing it, even if the indexing can take a little while, it saves time if you want to do multiple queries like this.

Merging dataframes

This can also be done by merging dataframes. This would fit more for a scenario where you have a lot more data than in these examples.

stkid_df = pd.DataFrame({"STK_ID": [4,2,6]})
df.merge(stkid_df, on='STK_ID')
   STK_ID   RPT_Date STK_Name  sales
0       2 1980-01-03    Cecil      2
1       4 1980-01-05     Eric      4
2       6 1980-01-07   George      4

Note

All the above methods work even if there are multiple rows with the same 'STK_ID'

In my case MySQL sever was not running. I restarted the MySQL server and issue was resolved.

//on ubuntu server
sudo /etc/init.d/mysql start

To avoid MySQL stop problem, you can use the "initctl" utility in Ubuntu 14.04 LTS Linux to make sure the service restarts in case of a failure or reboot. Please consider talking a snapshot of root volume (with mysql stopped) before performing this operations for data retention purpose[8]. You can use the following commands to manage the mysql service with "initctl" utility with stop and start operations.

$ sudo initctl stop mysql
$ sudo initctl start mysql

To verify the working, you can check the status of the service and get the process id (pid), simulate a failure by killing the "mysql" process and verify its status as running with new process id after sometime (typically within 1 minute) using the following commands.

$ sudo initctl status mysql         # get pid
$ sudo kill -9 <pid>                # kill mysql process
$ sudo initctl status mysql         # verify status as running after sometime

Note : In latest Ubuntu version now initctl is replaced by systemctl

You tried to do a.setText(a1). a1 is an int value, but setText() requires a string value. For this reason you need use String.valueOf(a1) to pass the value of a1 as a String and not as an int to a.setText(), like so:

a.setText(String.valueOf(a1))

that was the exact solution to the problem with my case.

Dir[File.join(__dir__, "/app/**/*.rb")].each do |file|
  require file
end

This will work recursively on your local machine and a remote (Like Heroku) which does not use relative paths.

Wrap it in a function:

create function now_utc() returns timestamp as $$
  select now() at time zone 'utc';
$$ language sql;

create temporary table test(
  id int,
  ts timestamp without time zone default now_utc()
);

Try this code,

this.startActivity(new Intent(v.getContext(), newactivity.class).addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION));

Even more concise if you are on python 2.7:

>>> t = ((1,'a'),(2,'b'))
>>> {y:x for x,y in t}
{'a':1, 'b':2}

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

• Why do we use rt.jar file in java project ?

Basically, rt.jar contains all of the compiled class files for the base Java Runtime ("rt") Environment. Normally, javac should know the path to this file

Java SE is use for the desktop applications and simple core functions. Java EE is used for desktop, but also web development, networking, and advanced things.

I would suggest the use of jquery mate.

With jQuery you would then be able to get the id of this element by

$(this).attr('id');

without jquery, if I remember correctly we used to access the id with a

this.id

Hope that helps :)

Here's how I did it in Excel 2003 using conditional formatting.

To apply conditional formatting to Sheet1 using values from Sheet2, you need to mirror the values into Sheet1.

Creating a mirror of Sheet2, column B in Sheet 1

1. Go to Sheet1.
2. Insert a new column by right-clicking column A's header and selecting "Insert".

3. Enter the following formula into A1:

   =IF(ISBLANK(Sheet2!B1),"",Sheet2!B1)

4. Copy A1 by right-clicking it and selecting "Copy".
5. Paste the formula into column A by right-clicking its header and selecting "Paste".

Sheet1, column A should now exactly mirror the values in Sheet2, column B.

(Note: if you don't like it in column A, it works just as well to have it in column Z or anywhere else.)

Applying the conditional formatting

1. Stay on Sheet1.
2. Select column B by left-clicking its header.
3. Select the menu item Format > Conditional Formatting...

4. Change Condition 1 to "Formula is" and enter this formula:

   =MATCH(B1,$A:$A,0)

5. Click the Format... button and select a green background.

You should now see the green background applied to the matching cells in Sheet1.

Hiding the mirror column

1. Stay on Sheet1.
2. Right-click the header on column A and select "Hide".

This should automatically update Sheet1 whenever anything in Sheet2 is changed.

For a quick-and-dirty script I wrote, I did it this way:

PAGER=cat git diff ...

If you want to throw an exception from the catch block you must inform your method/class/etc. that it needs to throw said exception. Like so:

public void doStuff() throws MyException {
    try {
        //Stuff
    } catch(StuffException e) {
        throw new MyException();
    }
}

And now your compiler will not yell at you :)

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

You can OpenGL without a wrapper and use it natively in C#. Just as Jeff Mc said, you would have to import all the functions you need with DllImport.

What he left out is having to create context before you can use any of the OpenGL functions. It's not hard, but there are few other not-so-intuitive DllImports that need to be done.

I have created an example C# project in VS2012 with almost the bare minimum necessary to get OpenGL running on Windows box. It only paints the window blue, but it should be enough to get you started. The example can be found at http://www.glinos-labs.org/?q=programming-opengl-csharp. Look for the No Wrapper example at the bottom.

Use MaxBy from the morelinq project:

items.MaxBy(i => i.ID);

Whether encrypted be the same when plain text is encrypted with the same key depends of algorithm and protocol. In cryptography there is initialization vector IV: http://en.wikipedia.org/wiki/Initialization_vector that used with various ciphers makes that the same plain text encrypted with the same key gives various cipher texts.

I advice you to read more about cryptography on Wikipedia, Bruce Schneier http://www.schneier.com/books.html and "Beginning Cryptography with Java" by David Hook. The last book is full of examples of usage of http://www.bouncycastle.org library.

If you are interested in cryptography the there is CrypTool: http://www.cryptool.org/ CrypTool is a free, open-source e-learning application, used worldwide in the implementation and analysis of cryptographic algorithms.

setInterval()

setInterval is a time interval based code execution method that has the native ability to repeatedly run specified script when the interval is reached. It should not be nested into its callback function by the script author to make it loop, since it loops by default. It will keep firing at the interval unless you call clearInterval().

if you want to loop code for animations or clocks Then use setInterval.

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setInterval(doStuff, 5000);

setTimeout()

setTimeout is a time based code execution method that will execute script only one time when the interval is reached, and not repeat again unless you gear it to loop the script by nesting the setTimeout object inside of the function it calls to run. If geared to loop, it will keep firing at the interval unless you call clearTimeout().

function doStuff() {
alert("run your code here when time interval is reached");
}
var myTimer = setTimeout(doStuff, 5000);

if you want something to happen one time after some seconds Then use setTimeout... because it only executes one time when the interval is reached.

Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.

It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.

The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

You can change easy marker label css without use any extra plugin.

var marker = new google.maps.Marker({
        position: this.overlay_text,
        draggable: true,
        icon: '',
        label: {
          text: this.overlay_field_text,
          color: '#fff',
          fontSize: '20px',
          fontWeight: 'bold',
          fontFamily: 'custom-label'
        },
        map:map
      });
      marker.setMap(map);

$("[style*='custom-label']").css({'text-shadow': '2px 2px #000'})

As a more brute force method that I found worked for me:

First wrap the text inside the button in a span, and then apply this css to that span

var spanStyle = {
      position: "absolute",
      top: "50%",
      left: "50%",
      transform: "translate(-50%, -50%)"
    }

*above setup for inline styling

Simply show a new window with two buttons. Add property to contain user result.

Debug and Release are just labels for different solution configurations. You can add others if you want. A project I once worked on had one called "Debug Internal" which was used to turn on the in-house editing features of the application. You can see this if you go to Configuration Manager... (it's on the Build menu). You can find more information on MSDN Library under Configuration Manager Dialog Box.

Each solution configuration then consists of a bunch of project configurations. Again, these are just labels, this time for a collection of settings for your project. For example, our C++ library projects have project configurations called "Debug", "Debug_Unicode", "Debug_MT", etc.

The available settings depend on what type of project you're building. For a .NET project, it's a fairly small set: #defines and a few other things. For a C++ project, you get a much bigger variety of things to tweak.

In general, though, you'll use "Debug" when you want your project to be built with the optimiser turned off, and when you want full debugging/symbol information included in your build (in the .PDB file, usually). You'll use "Release" when you want the optimiser turned on, and when you don't want full debugging information included.

This is because findViewById() searches in the activity_main layout, while the button is located in the fragment's layout fragment_main.

Move that piece of code in the onCreateView() method of the fragment:

//...

View rootView = inflater.inflate(R.layout.fragment_main, container, false);
Button buttonClick = (Button)rootView.findViewById(R.id.button);
buttonClick.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        onButtonClick((Button) view);
    }
});

Notice that now you access it through rootView view:

Button buttonClick = (Button)rootView.findViewById(R.id.button);

otherwise you would get again NullPointerException.
