Create two partial indexes:

CREATE UNIQUE INDEX favo_3col_uni_idx ON favorites (user_id, menu_id, recipe_id)
WHERE menu_id IS NOT NULL;

CREATE UNIQUE INDEX favo_2col_uni_idx ON favorites (user_id, recipe_id)
WHERE menu_id IS NULL;

This way, there can only be one combination of (user_id, recipe_id) where menu_id IS NULL, effectively implementing the desired constraint.

Possible drawbacks: you cannot have a foreign key referencing (user_id, menu_id, recipe_id), you cannot base CLUSTER on a partial index, and queries without a matching WHERE condition cannot use the partial index. (It seems unlikely you'd want a FK reference three columns wide - use the PK column instead).

If you need a complete index, you can alternatively drop the WHERE condition from favo_3col_uni_idx and your requirements are still enforced.
The index, now comprising the whole table, overlaps with the other one and gets bigger. Depending on typical queries and the percentage of NULL values, this may or may not be useful. In extreme situations it might even help to maintain all three indexes (the two partial ones and a total on top).

Aside: I advise not to use mixed case identifiers in PostgreSQL.

class Test extends Thread
{
    public void run(){  
        try{  
            Thread.sleep(10000);  
        }catch(InterruptedException e){  
            System.out.println("test1");
            throw new RuntimeException("Thread interrupted..."+e);  
        }  

    }  

    public static void main(String args[]){  
        Test t1=new Test1();  
        t1.start();  
        try{  
            t1.interrupt();  
        }catch(Exception e){
            System.out.println("test2");
            System.out.println("Exception handled "+e);
        }  

    }  
}

Its output doesn't contain test2 , so its not handling runtime exception. @jon skeet, @Jan Zyka

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

and doesnt give any clues

Yes it does, unfortunately your code is ignoring all of those clues. Take a look at your exception handler:

catch (OleDbException  ex)
{
    MessageBox.Show(ex.Source);
    conn.Close();
}

All you're examining is the source of the exception. Which, in this case, is "Microsoft Access Database Engine". You're not examining the error message itself, or the stack trace, or any inner exception, or anything useful about the exception.

Don't ignore the exception, it contains information about what went wrong and why.

There are various logging tools out there (NLog, log4net, etc.) which can help you log useful information about an exception. Failing that, you should at least capture the exception message, stack trace, and any inner exception(s). Currently you're ignoring the error, which is why you're not able to solve the error.

In your debugger, place a breakpoint inside the catch block and examine the details of the exception. You'll find it contains a lot of information.

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError

Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:

• second
• minute
• hour
• day
• week
• month
• year

This unit is then used find a format for the axis labels. The default patterns are:

second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'

If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats option for that level include %d or %e. These are the available patters:

• %a: Short weekday, like 'Mon'.
• %A: Long weekday, like 'Monday'.
• %d: Two digit day of the month, 01 to 31.
• %e: Day of the month, 1 through 31.
• %b: Short month, like 'Jan'.
• %B: Long month, like 'January'.
• %m: Two digit month number, 01 through 12.
• %y: Two digits year, like 09 for 2009.
• %Y: Four digits year, like 2009.
• %H: Two digits hours in 24h format, 00 through 23.
• %I: Two digits hours in 12h format, 00 through 11.
• %l (Lower case L): Hours in 12h format, 1 through 11.
• %M: Two digits minutes, 00 through 59.
• %p: Upper case AM or PM.
• %P: Lower case AM or PM.
• %S: Two digits seconds, 00 through 59

It is not necessary to declare the interface abstract.

Just like declaring all those methods public (which they already are if the interface is public) or abstract (which they already are in an interface) is redundant.

No one is stopping you, though.

Other things you can explicitly state, but don't need to:

• call super() on the first line of a constructor
• extends Object
• implement inherited interfaces

Is there other rules that applies with an abstract interface?

An interface is already "abstract". Applying that keyword again makes absolutely no difference.

Well we don't actually need inspect here.

>>> func = lambda x, y: (x, y)
>>> 
>>> func.__code__.co_argcount
2
>>> func.__code__.co_varnames
('x', 'y')
>>>
>>> def func2(x,y=3):
...  print(func2.__code__.co_varnames)
...  pass # Other things
... 
>>> func2(3,3)
('x', 'y')
>>> 
>>> func2.__defaults__
(3,)

For Python 2.5 and older, use func_code instead of __code__, and func_defaults instead of __defaults__.

XPath 1.0 doesn't handle regex natively, you could try something like

//*[starts-with(@id, 'sometext') and ends-with(@id, '_text')]

(as pointed out by paul t, //*[boolean(number(substring-before(substring-after(@id, "sometext"), "_text")))] could be used to perform the same check your original regex does, if you need to check for middle digits as well)

In XPath 2.0, try

//*[matches(@id, 'sometext\d+_text')]

//add the two day

$date = "**2-4-2016**"; //stored into date to variable

echo date("d-m-Y",strtotime($date.**' +2 days'**));

//print output
**4-4-2016**

Reading the Spark documentation I found an easier solution.

Since version 1.4 of spark there is a function drop(col) which can be used in pyspark on a dataframe.

You can use it in two ways

1. df.drop('age').collect()
2. df.drop(df.age).collect()

The font may exist with different names, and not at all on some systems, so you need to use different variations and fallback to get the closest possible look on all systems:

font-family: "Comic Sans MS", "Comic Sans", cursive;

Be careful what you use this font for, though. Many consider it as ugly and overused, so it should not be use for something that should look professional.

public class Book
{
    public int number;
    public String title;
    public String language;
    public int price;

    // Add constructor, get, set, as needed.
}

then declare your array as:

Book[] books = new Book[3];

EDIT: In response to O.P.'s confusion, Book should be an object, not an array. Each book should be created on it's own (via a properly designed constructor) and then added to the array. In fact, I wouldn't use an array, but an ArrayList. In other words, you are trying to force data into containers that aren't suitable for the task at hand.

I would venture that 50% of programming is choosing the right data structure for your data. Algorithms naturally follow if there is a good choice of structure.

When properly done, you get your UI class to look like: Edit: Generics added to the following code snippet.

...
ArrayList<Book> myLibrary = new ArrayList<Book>();
myLibrary.add(new Book(1, "Thinking In Java", "English", 4999));
myLibrary.add(new Book(2, "Hacking for Fun and Profit", "English", 1099);

etc.

now you can use the Collections interface and do something like:

int total = 0;
for (Book b : myLibrary)
{
   total += b.price;
   System.out.println(b); // Assuming a valid toString in the Book class
}
System.out.println("The total value of your library is " + total);

Well, the _id is an object in your example, so you just need to pass an object

'db.test_users.remove({"_id": { "$oid" : "4d513345cc9374271b02ec6c" }})'

This should work

Edit: Added trailing paren to ensure that it compiled.

This should work:

<div style="text-align:center;">
  <table style="margin: 0 auto;">
    <!-- table markup here. -->
  </table>
</div>

For some reason, the accepted answer worked for me only if being used once on the page, but in my case I was trying to save data on many elements on the page and the data was somehow lost on all except the first element.

As an alternative, I ended up writing the data out to the dom and parsing it back in when needed. Perhaps it's less efficient, but worked well for my purpose because I'm really prototyping data and not writing this for production.

To save the data I used:

$('#myElement').attr('data-key', JSON.stringify(jsonObject));

To then read the data back is the same as the accepted answer, namely:

var getBackMyJSON = $('#myElement').data('key');

Doing it this way also made the data appear in the dom if I were to inspect the element with Chrome's debugger.

sort() was deprecated for DataFrames in favor of either:

• sort_values() to sort by column(s)
• sort_index() to sort by the index

sort() was deprecated (but still available) in Pandas with release 0.17 (2015-10-09) with the introduction of sort_values() and sort_index(). It was removed from Pandas with release 0.20 (2017-05-05).

here is the simple method without any special libraries are special function,

name_list = ["Mike","Matt","Nancy","Adam","Jenny","Nancy","Carl"];_x000D_
get_uniq = name_list.filter(function(val,ind) { return name_list.indexOf(val) == ind; })_x000D_
_x000D_
console.log("Original name list:"+name_list.length, name_list)_x000D_
console.log("\n Unique name list:"+get_uniq.length, get_uniq)

This is my solution using pure Win32/C++ based on the top answer. The idea is to wrap everything required into one function without the need for external callback functions or structures:

#include <utility>

HWND FindTopWindow(DWORD pid)
{
    std::pair<HWND, DWORD> params = { 0, pid };

    // Enumerate the windows using a lambda to process each window
    BOOL bResult = EnumWindows([](HWND hwnd, LPARAM lParam) -> BOOL 
    {
        auto pParams = (std::pair<HWND, DWORD>*)(lParam);

        DWORD processId;
        if (GetWindowThreadProcessId(hwnd, &processId) && processId == pParams->second)
        {
            // Stop enumerating
            SetLastError(-1);
            pParams->first = hwnd;
            return FALSE;
        }

        // Continue enumerating
        return TRUE;
    }, (LPARAM)&params);

    if (!bResult && GetLastError() == -1 && params.first)
    {
        return params.first;
    }

    return 0;
}

Crystal Reports SP 19 does not support Visual Studio 2017. According to SAP they are targeting Visual Studio 2017 compatibility in SP 20 which is tentatively scheduled for June 2017.

I use this library: https://github.com/XamlAnimatedGif/WpfAnimatedGif

First, install library into your project (using Package Manager Console):

    PM > Install-Package WpfAnimatedGif

Then, use this snippet into XAML file:

    <Window x:Class="WpfAnimatedGif.Demo.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:gif="http://wpfanimatedgif.codeplex.com"
        Title="MainWindow" Height="350" Width="525">
        <Grid>
            <Image gif:ImageBehavior.AnimatedSource="Images/animated.gif" />
        ...

I hope helps.

Swift 3 solution.

All these did NOT work.

1. Clicking on Module on right pane did NOT work.
2. Adding @obj did NOT work.
3. Restarting did NOT work.
4. Moving to desktop as xcode breaks for longer path is NOT working. ...

This worked finally.

Just create new directory and create a new project inside that. Add the files except Main.sotryboard.

Now copy the view controllers from previous project and paste it into new Main.storyboard.

Voila ! This works.

I know I'm coming to this late, but what the heck.

I've got almost the exact same code as Kris, using just one Activity but with 2 different layouts/views, and I want to switch between the layouts at will.

As a test, I added 2 menu options, each one switches the view:

public boolean onOptionsItemSelected(MenuItem item) {

        switch (item.getItemId()) {
            case R.id.item1:
                setContentView(R.layout.main);
                return true;
            case R.id.item2:
                setContentView(R.layout.alternate);
                return true;
            default:
                return super.onOptionsItemSelected(item);
        }
    }

Note, I've got one Activity class. This works perfectly. So I have no idea why people are suggesting using different Activities / Intents. Maybe someone can explain why my code works and Kris's didn't.

My favoured method for doing this looks something like:

<xsl:stylesheet>

<xsl:output method='text'/>

<xsl:variable name='newline'><xsl:text>
</xsl:text></xsl:variable>

<!-- note that the layout there is deliberate -->

...

</xsl:stylesheet>

Then, whenever you want to output a newline (perhaps in csv) you can output something like the following:

<xsl:value-of select="concat(elem1,elem2,elem3,$newline)" />

I've used this technique when outputting sql from xml input. In fact, I tend to create variables for commas, quotes and newlines.

SELECT `name` FROM `table` WHERE `name` LIKE '%Stylus % 2100%'

Clean and simple:

awk '{print $2}' file.txt | paste -s -d, -

Try it like this instead, move your myclass items inside a main method:

    class UserInput {
      public void name() {
        System.out.println("This is a test.");
      }
    }

    public class MyClass {

        public static void main( String args[] )
        {
            UserInput input = new UserInput();
            input.name();
        }

    }

For those that use Fish shell you can use the following function then call it in ~/.config/fish/config.fish or in a separate configuration file in ~/.config/fish/conf.d/loadsshkeys.fish. It will load all keys that start with id_rsa into the ssh-agent.

# Load all ssh keys that start with "id_rsa"
function loadsshkeys
  set added_keys (ssh-add -l)
   for key in (find ~/.ssh/ -not -name "*.pub" -a -iname "id_rsa*")
    if test ! (echo $added_keys | grep -o -e $key)
      ssh-add "$key"
    end
  end
end

# Call the function to run it.
loadsshkeys

If you want to have the ssh-agent auto started when you open a terminal you can use tuvistavie/fish-ssh-agent to do this.

We've solved this, although we didn't think having the addListener outside of the for would make any difference, it seems to. Here's the answer:

Create a new function with your information for the infoWindow in it:

function addInfoWindow(marker, message) {

            var infoWindow = new google.maps.InfoWindow({
                content: message
            });

            google.maps.event.addListener(marker, 'click', function () {
                infoWindow.open(map, marker);
            });
        }

Then call the function with the array ID and the marker you want to create:

addInfoWindow(marker, hotels[i][3]);

Java 8 introduced CompletableFuture available in package java.util.concurrent.CompletableFuture, can be used to make a asynch call :

CompletableFuture.runAsync(() -> {
    // method call or code to be asynch.
});

I'll go ahead and throw this answer in because it is all I needed when I had the same question:

Date currentDate = new Date(System.currentTimeMillis());

currentDate is now your current date in a Java Date object.

I like this thread because it documents the default locations for various postgresql.conf files on various architectures...

However, I've also gotten in trouble by relying on those defaults on installations where they have specified alternate locations. One way to find out where a particular config file is by querying the database directly:

select * from pg_settings where name='config_file'

Drop the where clause to see all the settings, which can also be illuminating because it shows where data directories, pg_hba.conf, etc. are.

Another approach that is especially useful if you want to store data coming from an external API or a DB would be this:

1. Create a class that represent your data model

   export class Data{
       private id:number;
       private text: string;
   
       constructor(id,text) {
           this.id = id;
           this.text = text;
       }
   

2. In your component class you create an empty array of type Data and populate this array whenever you get a response from API or whatever data source you are using

   export class AppComponent {
       private search_key: string;
       private dataList: Data[] = [];
   
       getWikiData() {
          this.httpService.getDataFromAPI()
           .subscribe(data => {
             this.parseData(data);
           });
        }
   
       parseData(jsonData: string) {
       //considering you get your data in json arrays
       for (let i = 0; i < jsonData[1].length; i++) {
            const data = new WikiData(jsonData[1][i], jsonData[2][i]);
            this.wikiData.push(data);
       }
     }
   }
   

Try

python --version 

or

python -V

This will return a current python version in terminal.

I also had this problem. To sort out the problem of spaces in the middle of the string this line of code always works:

String field = field.replaceAll("\\s+", "");

I believe that one of those will fit your need

1 - Undo commit and keep all files staged: git reset --soft HEAD~;

2 - Undo commit and unstage all files: git reset HEAD~;

3 - Undo the commit and completely remove all changes: git reset --hard HEAD~;

here is were I found the answer

In my case, I am not using the built in ajax api to feed Json to the table (this is due to some formatting that was rather difficult to implement inside the datatable's render callback).

My solution was to create the variable in the outer scope of the onload functions and the function that handles the data refresh (var table = null, for example).

Then I instantiate my table in the on load method

$(function () {
            //.... some code here
            table = $("#detailReportTable").DataTable();
            .... more code here
        });

and finally, in the function that handles the refresh, i invoke the clear() and destroy() method, fetch the data into the html table, and re-instantiate the datatable, as such:

function getOrderDetail() {
            table.clear();
            table.destroy();
            ...
            $.ajax({
             //.....api call here
            });
            ....
            table = $("#detailReportTable").DataTable();
   }

I hope someone finds this useful!

I have built an module for this if you want to add styles based on a condition like this:

multipleStyles(styles.icon, { [styles.iconRed]: true })

https://www.npmjs.com/package/react-native-multiple-styles

Size detects duplicates, it will return the number of unique values

const set1 = new Set([1, 2, 3, 4, 5, 5, 5, 6]);
console.log(set1.size);
// expected output: 6

For enter event handling you can use

1. @keyup.enter or
2. @keyup.13

13 is the keycode of enter. For @ key event, the keycode is 50. So you can use @keyup.50.

For example:

<input @keyup.50="atPress()" />

You can use the "ORDER BY DESC" option, then put it back in the original order:

(SELECT * FROM tablename ORDER BY id DESC LIMIT 10) ORDER BY id;

Append a semicolon to the following line to fix the issue.

font-family:    Arial, Helvetica, sans-serif;

Check permissions of the file, if it is good check parent directories

            destinationId: input.destinationId,
            radius: input.radius,
            search: input.search
        },
        function() { console.log("setState completed", this.state) }

=VLOOKUP(LEFT(A1,3),LEFT(B$2:B$22,3), 1,FALSE)

LEFT() truncates the first n character of a string, and you need to do it in both columns. The third parameter of VLOOKUP is the number of the column to return with. So if your range is not only B$2:B$22 but B$2:C$22 you can choose to return with column B value (1) or column C value (2)

This issue was with me also. Simple trick for it.

 @NgModule({
  imports: [
   .....       
  ],
 declarations: [
  ......
 ],

 providers: [...],
 bootstrap: [...]
 })

use it as in above order.first imports then declarations.It worked for me.

I guess the right answer is that: there is no way to make it shorter. There are some techniques such as the ones in the comments, but I don't see myself using them. I think it's better to write a "if" block than to use those techniques. and yes.. before anybody mentions it yet again :) "ideally" the code should be desgined such that list should never be a null

This question may be old, but for anybody in future that wants a simple way to achieve complex shadow effects check out my library here https://github.com/BluRe-CN/ComplexView

Using the library, you can change shadow colors, tweak edges and so much more. Here's an example to achieve what you seek for.

<com.blure.complexview.ComplexView
        android:layout_width="400dp"
        android:layout_height="600dp"
        app:radius="10dp"
        app:shadow="true"
        app:shadowSpread="2">

        <com.blure.complexview.ComplexView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:color="#fdfcfc"
            app:radius="10dp" />
    </com.blure.complexview.ComplexView>

To change the shadow color, use app:shadowColor="your color code".

This should be enough:

.nav.navbar-nav li a:hover {
  color: red;
}

404 Not Found technically means that uri does not currently map to a resource. In your example, I interpret a request to http://mywebsite/api/user/13 that returns a 404 to imply that this url was never mapped to a resource. To the client, that should be the end of conversation.

To address concerns with ambiguity, you can enhance your API by providing other response codes. For example, suppose you want to allow clients to issue GET requests the url http://mywebsite/api/user/13, you want to communicate that clients should use the canonical url http://mywebsite/restapi/user/13. In that case, you may want to consider issuing a permanent redirect by returning a 301 Moved Permanently and supply the canonical url in the Location header of the response. This tells the client that for future requests they should use the canonical url.

Here's a simple extension method that returns each row as an IEnumerable<T>. This has the advantage of not using any extra memory:

public static class Array2dExt
{
    public static IEnumerable<IEnumerable<T>> Rows<T>(this T[,] array)
    {
        for (int r = array.GetLowerBound(0); r <= array.GetUpperBound(0); ++r)
            yield return row(array, r);
    }

    static IEnumerable<T> row<T>(T[,] array, int r)
    {
        for (int c = array.GetLowerBound(1); c <= array.GetUpperBound(1); ++c)
            yield return array[r, c];
    }
}

Sample usage:

static void Main()
{
    string[,] siblings = { { "Mike", "Amy" }, { "Mary", "Albert" }, {"Fred", "Harry"} };

    foreach (var row in siblings.Rows())
        Console.WriteLine("{" + string.Join(", ", row) + "}");
}

1. Add the file to your project.
2. Go to the Properties of that file.
3. Set "Build Action" to Embedded Resource.
4. Set "Copy to Output Directory" to Copy Always.

No command sbt found

It's saying that sbt is not on your path. Try to run ./sbt from ~/bin/sbt/bin or wherever the sbt executable is to verify that it runs correctly. Also check that you have execute permissions on the sbt executable. If this works , then add ~/bin/sbt/bin to your path and sbt should run from anywhere.

See this question about adding a directory to your path.

To verify the path is set correctly use the which command on LINUX. The output will look something like this:

$ which sbt
/usr/bin/sbt

Lastly, to verify sbt is working try running sbt -help or likewise. The output with -help will look something like this:

$ sbt -help
Usage: sbt [options]

  -h | -help         print this message

Just Click on Build -> Rebuild Project option in your Android Studio.

Another much simpler possibility is that one of your property names is wrong (probably one you just changed in the class). This is what it was for me in RazorPages .NET Core 3.

A simple method along the lines of:

bool AreAllColumnsEmpty(DataRow dr)
{
 if (dr == null)
 {
  return true;
 }
 else
 {
  foreach(var value in dr.ItemArray)
  {
    if (value != null)
    {
      return false;
    }
  }
  return true;
 }
}

Should give you what you're after, and to make it "nice" (as there's nothing as far as I'm aware, in the Framework), you could wrap it up as an extension method, and then your resultant code would be:

if (datarow.AreAllColumnsEmpty())
{
}
else
{
}

Entering: /usr/bin/gcc worked for me.

import java.util.Collections;

import java.util.List;

import java.util.ArrayList;

   str.add(new Student(104, "bbb"));

   str.add(new Student(103, "ccc"));

   str.add(new Student(105, "ddd"));

   str.add(new Student(104, "eee"));

   str.add(new Student(102, "fff"));

CodeLens is not available in the Community editions. You need Professional or higher to switch it on.

In VS2015, one way to "get" CodeLens was to install the SQL Server Developer Tools (SSDT) but I believe this has been rectified in VS2017.

Still you can get all method reference by right clicking on the method and "Find All references"

function getRandomString($length) {
  $salt = array_merge(range('a', 'z'), range(0, 9));
  $maxIndex = count($salt) - 1;

  $result = '';
  for ($i = 0; $i < $length; $i++) {
    $index = mt_rand(0, $maxIndex);
    $result .= $salt[$index];
  }
  return $result
}

You can use the following code:

Intent i = new Intent(OldActivity.this, NewActivity.class);

i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);

startActivity(i);

Yes, you can do this in PHP e.g. in

Silex or Symfony3

using subrequest

$postParams = array(
    'email' => $request->get('email'),
    'agree_terms' => $request->get('agree_terms'),
);

$subRequest = Request::create('/register', 'POST', $postParams);
return $app->handle($subRequest, HttpKernelInterface::SUB_REQUEST, false);

After some searching, I could not find an easy way to get information on all of the tables. There is a handy stored procedure named sp_spaceused that will return all of the space used by the database. If provided with a table name, it returns the space used by that table. However, the results returned by the stored procedure are not sortable, since the columns are character values.

The following script will generate the information I'm looking for.

create table #TableSize (
    Name varchar(255),
    [rows] int,
    reserved varchar(255),
    data varchar(255),
    index_size varchar(255),
    unused varchar(255))
create table #ConvertedSizes (
    Name varchar(255),
    [rows] int,
    reservedKb int,
    dataKb int,
    reservedIndexSize int,
    reservedUnused int)

EXEC sp_MSforeachtable @command1="insert into #TableSize
EXEC sp_spaceused '?'"
insert into #ConvertedSizes (Name, [rows], reservedKb, dataKb, reservedIndexSize, reservedUnused)
select name, [rows], 
SUBSTRING(reserved, 0, LEN(reserved)-2), 
SUBSTRING(data, 0, LEN(data)-2), 
SUBSTRING(index_size, 0, LEN(index_size)-2), 
SUBSTRING(unused, 0, LEN(unused)-2)
from #TableSize

select * from #ConvertedSizes
order by reservedKb desc

drop table #TableSize
drop table #ConvertedSizes

I'm just going to do this

def function():
  while True:
    #code here

    break

Use "break" to stop the function.

I've loved weinre! How to use it:

First, put on your index.html (ensure app.settings.debugUrl is set before this):

  <!-- Weinre debugging -->
  <script type="text/javascript">
    if (app.settings.debugUrl) {
      document.addEventListener("DOMContentLoaded", function(event) { 
        var s = document.createElement("script")
        s.setAttribute("src", app.settings.debugUrl+"/target/target-script-min.js#anonymous")
        document.getElementsByTagName("body")[0].appendChild(s)
      }); 
    }   
  </script>

Then:

• install: sudo npm install -g weinre
• run: weinre --boundHost -all-
• open on browser: http://localhost:8080/client/#anonymous
• watch targets appear as you open the app

Based on http://www.broken-links.com/2013/06/28/remote-debugging-with-weinre/

I believe you need to .f file as a parameter, not as a command-single-string. same with the "--domain "+i, which i would split in two elements of the list. Assuming that:

• you have the path set for FORTRAN executable,
• the ~/ is indeed the correct way for the FORTRAN executable

I would change this line:

subprocess.Popen(["FORTRAN ~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain "+i])

to

subprocess.Popen(["FORTRAN", "~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f", "--domain", i])

If that doesn't work, you should do a os.path.exists() for the .f file, and check that you can launch the FORTRAN executable without any path, and set the path or system path variable accordingly

[EDIT 6-Mar-2017]

As the exception, detailed in the original post, is a python exception from subprocess; it is likely that the WinError 2 is because it cannot find FORTRAN

I highly suggest that you specify full path for your executable:

for i in input:
    exe = r'c:\somedir\fortrandir\fortran.exe'
    fortran_script = r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f'
    subprocess.Popen([exe, fortran_script, "--domain", i])

if you need to convert the forward-slashes to backward-slashes, as suggested in one of the comments, you can do this:

for i in input:
    exe = os.path.normcase(r'c:\somedir\fortrandir\fortran.exe')
    fortran_script = os.path.normcase(r'~/C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[EDIT 7-Mar-2017]

The following line is incorrect:

exe = os.path.normcase(r'~/C:/Program Files (x86)/Silverfrost/ftn95.exe'

I am not sure why you have ~/ as a prefix for every path, don't do that.

for i in input:
    exe = os.path.normcase(r'C:/Program Files (x86)/Silverfrost/ftn95.exe'
    fortran_script = os.path.normcase(r'C:/Users/Vishnu/Desktop/Fortran_Program_Rum/phase1.f')
    i = os.path.normcase(i)
    subprocess.Popen([exe, fortran_script, "--domain", i])

[2nd EDIT 7-Mar-2017]

I do not know this FORTRAN or ftn95.exe, does it need a shell to function properly?, in which case you need to launch as follows:

subprocess.Popen([exe, fortran_script, "--domain", i], shell = True)

You really need to try to launch the command manually from the working directory which your python script is operating from. Once you have the command which is actually working, then build up the subprocess command.

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

The error message explains it pretty well:

ValueError: The truth value of an array with more than one element is ambiguous. 
Use a.any() or a.all()

What should bool(np.array([False, False, True])) return? You can make several plausible arguments:

(1) True, because bool(np.array(x)) should return the same as bool(list(x)), and non-empty lists are truelike;

(2) True, because at least one element is True;

(3) False, because not all elements are True;

and that's not even considering the complexity of the N-d case.

So, since "the truth value of an array with more than one element is ambiguous", you should use .any() or .all(), for example:

>>> v = np.array([1,2,3]) == np.array([1,2,4])
>>> v
array([ True,  True, False], dtype=bool)
>>> v.any()
True
>>> v.all()
False

and you might want to consider np.allclose if you're comparing arrays of floats:

>>> np.allclose(np.array([1,2,3+1e-8]), np.array([1,2,3]))
True

Another option:

this.form.value['nameOfControl']

if ((ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) && (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) && (ContextCompat.checkSelfPermission(MainActivity.this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED)) {

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {

        requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA},
                MY_PERMISSIONS_REQUEST_WRITE_EXTERNAL_STORAGE);
    }
} 

You probably finally realized this between posting this question and today, but the very nature of selectors makes it impossible to navigate through hierarchically unrelated HTML elements.

Or, to put it simply, since you said in your comment that

there are no uniform parent containers

... it's just not possible with selectors alone, without modifying the markup in some way as shown by the other answers.

You have to use the jQuery .eq() solution.

You can use routerLink in the following manner,

<input type="button" value="Add Bulk Enquiry" [routerLink]="['../addBulkEnquiry']" class="btn">

or use <button [routerLink]="['./url']"> in your case, for more info you could read the entire stacktrace on github https://github.com/angular/angular/issues/9471

the other methods are also correct but they create a dependency on the component file.

Hope your concern is resolved.

You can use:

SELECT COUNT(1) FROM MyTable WHERE ... 

or

WHERE [NOT] EXISTS 
( SELECT 1 FROM MyTable WHERE ... )

This will be more efficient than SELECT * since you're simply selecting the value 1 for each row, rather than all the fields.

There's also a subtle difference between COUNT(*) and COUNT(column name):

• COUNT(*) will count all rows, including nulls
• COUNT(column name) will only count non null occurrences of column name

In Xcode 10 the OS_ACTIVITY_MODE variable with disable (or default) value also turns off the NSLog no matter what.

So if you want to get rid of the console noise but not of your own logs, you could try the good old printf("") instead of the NSLog since it is not affected by the OS_ACTIVITY_MODE = disable.

But better check out the new os_log API here.

Firstly name isn't a valid attribute of an option element. Instead you could use a data parameter, like this:

<option value="foo" data-name="bar">Foo Bar</option>

The main issue you have is that the JS is looking at the name attribute of the select element, not the chosen option. Try this:

$('#band_type_choices').on('change', function() {         
    $('.checkboxlist').hide();
    $('#checkboxlist_' + $('option:selected', this).data("name")).css("display", "block");
});

Note the option:selected selector within the context of the select which raised the change event.

The following worked for me.

.back-ground {
   background-image: url("../assets/background.png");
   background-size: 100vw 100vh;
}

that worked to cover the entire background on different dimensions

Yup.

Measure-Command { .\do_something.ps1 }

Note that one minor downside of Measure-Command is that you see no stdout output.

[Update, thanks to @JasonMArcher] You can fix that by piping the command output to some commandlet that writes to the host, e.g. Out-Default so it becomes:

Measure-Command { .\do_something.ps1 | Out-Default }

Another way to see the output would be to use the .NET Stopwatch class like this:

$sw = [Diagnostics.Stopwatch]::StartNew()
.\do_something.ps1
$sw.Stop()
$sw.Elapsed

A simple AJAX call to your server, and then the serverside logic to get the ip address should do the trick.

$.getJSON('getip.php', function(data){
  alert('Your ip is: ' +  data.ip);
});

Then in php you might do:

<?php
/* getip.php */
header('Cache-Control: no-cache, must-revalidate');
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT');
header('Content-type: application/json');

if (!empty($_SERVER['HTTP_CLIENT_IP']))
{
  $ip=$_SERVER['HTTP_CLIENT_IP'];
}
elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))
{
  $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
}
else
{
  $ip=$_SERVER['REMOTE_ADDR'];
}
print json_encode(array('ip' => $ip));

Read: http://linuxmanpages.com/man1/sh.1.php & http://www.gnu.org/s/hello/manual/autoconf/Special-Shell-Variables.html

IFS The Internal Field Separator that is used for word splitting after expansion and to split lines into words with the read builtin command. The default value is ``''.

IFS is a shell environment variable so it will remain unchanged within the context of your Shell script but not otherwise, unless you EXPORT it. ALSO BE AWARE, that IFS will not likely be inherited from your Environment at all: see this gnu post for the reasons and more info on IFS.

You're code written like this:

IFS=","
for word in $(cat tmptest | sed -n 1'p' | tr ',' '\n'); do echo $word; done;

should work, I tested it on command line.

sh-3.2#IFS=","

It is possible if you can change the collection code that implements IEnumerable or IEnumerable (e.g. your own implementation of IList).

Create an Iterator doing this job for you, for example like the following implementation through the IEnumerable interface (assuming 'items' is a List field in this sample):

public IEnumerator<TObject> GetEnumerator()
{
    for (var i = items.Count - 1; i >= 0; i--)
    { 
        yield return items[i];
    }
}

IEnumerator IEnumerable.GetEnumerator()
{
    return GetEnumerator();
}

Because of this your List will iterate in reverse order through your list.

Just a hint: You should clearly state this special behaviour of your list within the documentation (even better by choosing a self-explaining class name like Stack or Queue, too).

There is already answer with Error Control Operator but it lacks of explanation. You can use @ operator with every expression and it hides errors (except of Fatal Errors).

@$test['test']; //PHP Notice:  Undefined variable: test

@(14/0); // PHP Warning:  Division by zero

//This is not working. You can't hide Fatal Errors this way.
@customFuntion(); // PHP Fatal error:  Uncaught Error: Call to undefined function customFuntion()

For debugging it's fast and perfect method. But you should never ever use it on production nor permanent include in your local version. It will give you a lot of unnecessary irritation.

You should consider instead:

1. Error reporting settings as mentioned in accepted answer.

error_reporting(E_ERROR | E_PARSE);

or from PHP INI settings

ini_set('display_errors','Off');

2. Catching exceptions

try {
    $var->method();
} catch (Error $e) {
    // Handle error
    echo $e->getMessage();
}

Another source of this problem: I found that in Debian 9, the Python httplib2 is hardcoded to insist on TLS v1.0. So any application that uses httplib2 to connect to a server that insists on better security fails with TLSV1_ALERT_PROTOCOL_VERSION.

I fixed it by changing

context = ssl.SSLContext(ssl.PROTOCOL_TLSv1)

to

context = ssl.SSLContext()

in /usr/lib/python3/dist-packages/httplib2/__init__.py .

Debian 10 doesn't have this problem.

Okay so little bit of digging and I found these gems from Bill Philips article on RecycleView

RecyclerView can do more than ListView, but the RecyclerView class itself has fewer responsibilities than ListView. Out of the box, RecyclerView does not:

• Position items on the screen
• Animate views
• Handle any touch events apart from scrolling

All of this stuff was baked in to ListView, but RecyclerView uses collaborator classes to do these jobs instead.

The ViewHolders you create are beefier, too. They subclass RecyclerView.ViewHolder, which has a bunch of methods RecyclerView uses. ViewHolders know which position they are currently bound to, as well as which item ids (if you have those). In the process, ViewHolder has been knighted. It used to be ListView’s job to hold on to the whole item view, and ViewHolder only held on to little pieces of it.

Now, ViewHolder holds on to all of it in the ViewHolder.itemView field, which is assigned in ViewHolder’s constructor for you.

You can use the react-moment package

-> https://www.npmjs.com/package/react-moment

Put in your file the next line:

import moment from "moment";

date_create: moment().format("DD-MM-YYYY hh:mm:ss")

string a = "", b = a , c = a, d = a, e = a, f =a;

simply change <div> to <tbody>

<table id="authenticationSetting" style="display: none">
  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>
      <td class="orionSummaryColumn">

     created_date as count_date
from
     table
group by

did you try something like

for o : AnyObject in self.subviews {
     if let v = o as? NSView {
         v.removeFromSuperview()
     }
}

Sometimes the following fix will work. Go to your build.gradle of your project and add google() into the repositories element and google() should be the at the top of all the repository.

This is the sample of the repositories block. What you need to do is to add google() or if that exists already, take that to the top of all the line inside repositories

    repositories {
    google()
    jcenter()
    maven { url 'https://maven.fabric.io/public' }
    maven { url "https://jitpack.io" }
    maven { url 'https://maven.google.com' }
}

I'm not sure what wget is, but to get a file from the web and store it locally, you can use NSData:

NSString *stringURL = @"http://www.somewhere.com/thefile.png";
NSURL  *url = [NSURL URLWithString:stringURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData )
{
  NSArray       *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString  *documentsDirectory = [paths objectAtIndex:0];  

  NSString  *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"filename.png"];
  [urlData writeToFile:filePath atomically:YES];
}

This answer comes a little bit late, but I just was in a similar need.

Observing the comments written by @ganaraj in the question, One use case I was in the need of is, passing a classname via a directive attribute to be added to a ng-repeat li tag in the template.

For example, use the directive like this:

<my-directive class2add="special-class" />

And get the following html:

<div>
    <ul>
       <li class="special-class">Item 1</li>
       <li class="special-class">Item 2</li>
    </ul>
</div>

The solution found here applied with templateUrl, would be:

app.directive("myDirective", function() {
    return {
        template: function(element, attrs){
            return '<div><ul><li ng-repeat="item in items" class="'+attrs.class2add+'"></ul></div>';
        },
        link: function(scope, element, attrs) {
            var list = element.find("ul");
        }
    }
});

Just tried it successfully with AngularJS 1.4.9.

Hope it helps.

You can create a temp table variable and insert the data into it, then insert the data into your actual table by selecting it from the temp table.

 declare @TableVar table 
 (
    firstCol varchar(50) NOT NULL,
    secondCol varchar(50) NOT NULL
 )

BULK INSERT @TableVar FROM 'PathToCSVFile' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
GO

INSERT INTO dbo.ExistingTable
(
    firstCol,
    secondCol
)
SELECT firstCol,
       secondCol
FROM @TableVar

GO

One technique is to create a copy of the collection you want to modify, change the copy as needed, then replace the original collection with the copy at the end.

What follows is the easiest way to install a Java application as system service in Linux.

Let's assume you are using systemd (which any modern distro nowadays does):

Firstly, create a service file in /etc/systemd/system named e.g. javaservice.service with this content:

[Unit]
Description=Java Service

[Service]
User=nobody
# The configuration file application.properties should be here:
WorkingDirectory=/data 
ExecStart=/usr/bin/java -Xmx256m -jar application.jar --server.port=8081
SuccessExitStatus=143
TimeoutStopSec=10
Restart=on-failure
RestartSec=5

[Install]
WantedBy=multi-user.target

Secondly, notify systemd of the new service file:

systemctl daemon-reload

and enable it, so it runs on boot:

systemctl enable javaservice.service

Eventually, you can use the following commands to start/stop your new service:

systemctl start javaservice
systemctl stop javaservice
systemctl restart javaservice
systemctl status javaservice

Provided you are using systemd, this is the most non-intrusive and clean way to set up a Java application as system-service.

What I like especially about this solution is the fact that you don't need to install and configure any other software. The shipped systemd does all the work for you, and your service behaves like any other system service. I use it in production for a while now, on different distros, and it just works as you would expect.

Another plus is that, by using /usr/bin/java, you can easily add jvm paramters such as -Xmx256m.

Also read the systemd part in the official Spring Boot documentation: http://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html

In my case, I've had to click on my project, then go to File > Properties > *servlet name* and click Restart servlet.

To remove button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(View.GONE);

To transparent Button in java code:

Button btn=(Button)findViewById(R.id.btn);
btn.setVisibility(View.INVISIBLE);

To remove button in Xml file:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"/>

To transparent button in Xml file:

<Button
android:id="@+id/btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="invisible"/>

first of all, try to give the format you want to the current date time of your server:

1. Obtain current date time

   $current_date = getdate();

2. Separate date and time to manage them as you wish:

$current_date_only = $current_date[year].'-'.$current_date[mon].'-'.$current_date[mday]; $current_time_only = $current_date['hours'].':'.$current_date['minutes'].':'.$current_date['seconds'];

3. Compare it depending if you are using donly date or datetime in your DB:

   $today = $current_date_only.' '.$current_time_only;

   or

   $today = $current_date_only;

   if($today < $expireDate)

hope it helps

While not in your code, another hard-to-spot error is when the % character is missing in an attempt of string formatting:

"foo %s bar %s coffee"("blah","asdf")

but it should be:

"foo %s bar %s coffee"%("blah","asdf")

The missing % would result in the same TypeError: 'str' object is not callable.

According to Oracle integration of OpenJDK & javaFX will be on Q1-2014 ( see roadmap : http://www.oracle.com/technetwork/java/javafx/overview/roadmap-1446331.html ). So, for the 1st question the answer is that you have to wait until then. For the 2nd question there is no other way. So, for now go with java swing or start javaFX and wait

I can relate to the problem, there should be a shorthand like...

border: 1px solid red top bottom left;

Of course that doesn't work! Kobi's answer gave me an idea. Let's say you want to do top, bottom and left, but not right. Instead of doing border-top: border-left: border-bottom: (three statements) you could do two like this, the zero cancels out the right side.

border: 1px dashed yellow;
border-width:1px 0 1px 1px;

Two statements instead of three, small improvement :-D

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

If I understood your question, try something like this

declare @dd varchar(50)='Jan 30 2013 12:00:00:000AM'

Select convert(varchar,(CONVERT(date,@dd,103)),103)

Update

SELECT
PREFIX_TableName.ColumnName1 AS Name,
PREFIX_TableName.ColumnName2 AS E-Mail,
convert(varchar,(CONVERT(date,PREFIX_TableName.ColumnName3,103)),103) AS TransactionDate,
PREFIX_TableName.ColumnName4 AS OrderNumber

Same problem here, in all browsers (IE, Chrome, FF). Upon startup the Fiddler Log tab showed the following:

"!WARNING Fiddler has detected that system or domain Group Policy has set ProxySettingsPerUser to 0. Unless Fiddler is run Elevated (e.g. Run As Administrator), it may not capture traffic from Internet Explorer and other programs. Current process IS running Elevated."

I'm in a huge corporate environment, with no connection to or info about group policy changes; it apparently just got applied one day. Thanks, bureaucracy :)

Anyway, that led me to messing around with IE proxy settings. Changing it from Automatic to 127.0.0.1 on port 8888 (the default configured port in Fiddler) worked. Kind of a pain, though, because I have to set it each time to override the group policy setting. And then I get cert errors, which is a known thing because Fiddler uses it's own, untrusted cert . . . and the beat goes on . . .

"2.7.0_bf4fda703454".split("_") gives a list of strings:

In [1]: "2.7.0_bf4fda703454".split("_")
Out[1]: ['2.7.0', 'bf4fda703454']

This splits the string at every underscore. If you want it to stop after the first split, use "2.7.0_bf4fda703454".split("_", 1).

If you know for a fact that the string contains an underscore, you can even unpack the LHS and RHS into separate variables:

In [8]: lhs, rhs = "2.7.0_bf4fda703454".split("_", 1)

In [9]: lhs
Out[9]: '2.7.0'

In [10]: rhs
Out[10]: 'bf4fda703454'

An alternative is to use partition(). The usage is similar to the last example, except that it returns three components instead of two. The principal advantage is that this method doesn't fail if the string doesn't contain the separator.

On Java 9 or later, Map.entry can be used, so long as you know that neither the key nor value will be null. If either value could legitimately be null, AbstractMap.SimpleEntry (as suggested in another answer) or AbstractMap.SimpleImmutableEntry would be the way to go.

private Map<String, AttributeType> mapConfig(Map<String, String> input, String prefix) {
   int subLength = prefix.length();
   return input.entrySet().stream().map(e -> 
      Map.entry(e.getKey().substring(subLength), AttributeType.GetByName(e.getValue())));
   }).collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
}

As explained in http://www.regular-expressions.info/anchors.html under the section "Strings Ending with a Line Break", \Z will generally match before the end of the last newline in strings that end in a newline. If you want to only match the end of the string, you need to use \z. The exception to this rule is Python.

In other words, to exclusively match an empty string, you need to use /\A\z/.

Based on @holdfenytolvaj answer.

It's recommended to put the image to the resources, than you can use it like this:

imageView = new ImageView("/gui.img/img.jpg");

First, your code does not contain a contact div, it has a contacts div!

In sidebar you have contact in the div at the bottom of the page you have contacts. I removed the final s for the code sample. (you also misspelled the projectslink id in the sidebar).

Second, take a look at some of the examples for click on the jQuery reference page. You have to use click like, object.click( function() { // Your code here } ); in order to bind a click event handler to the object.... Like in my example below. As an aside, you can also just trigger a click on an object by using it without arguments, like object.click().

Third, scrollTo is a plugin in jQuery. I don't know if you have the plugin installed. You can't use scrollTo() without the plugin. In this case, the functionality you desire is only 2 lines of code, so I see no reason to use the plugin.

Ok, now on to a solution.

The code below will scroll to the correct div if you click a link in the sidebar. The window does have to be big enough to allow scrolling:

// This is a functions that scrolls to #{blah}link
function goToByScroll(id) {
    // Remove "link" from the ID
    id = id.replace("link", "");
    // Scroll
    $('html,body').animate({
        scrollTop: $("#" + id).offset().top
    }, 'slow');
}

$("#sidebar > ul > li > a").click(function(e) {
    // Prevent a page reload when a link is pressed
    e.preventDefault();
    // Call the scroll function
    goToByScroll(this.id);
});

Live Example

( Scroll to function taken from here )

PS: Obviously you should have a compelling reason to go this route instead of using anchor tags <a href="#gohere">blah</a> ... <a name="gohere">blah title</a>

It is related to the VPC's feature called "DNS Hostnames". You can enable or disable it. Go to the VPC, under the Actions menu select the "Edit DNS Hostnames" item and then choose "Yes". After doing so, the public DNS of the EC2 instances should be displayed.

Addressing Steven's comment to Sam Dufel's answer

Thanks, sounds like that's the way to go. But I just realized that I only want the optional whitespace characters if they follow a newline. So for example, "c\n ats" or "ca\n ts" should match. But wouldn't want "c ats" to match if there is no newline. Any ideas on how that might be done?

This should do the trick:

/c(?:\n\s*)?a(?:\n\s*)?t(?:\n\s*)?s/

See this page for all the different variations of 'cats' that this matches.

You can also solve this using conditionals, but they are not supported in the javascript flavor of regex.

This piece of code allows you to get all objects within a JSON whose key is user-defined.

function main(obj = {}, property){
 const views = [];

 function traverse(o) {
    for (var i in o) {
      if(i === property) views.push(o[i]);
      if (!!o[i] && typeof(o[i])=="object") {
        console.log(i, o[i]);
        traverse(o[i]);
      } else {
        console.log(i, o[i]);
      }
    }
    }

  traverse(obj);
  return views;

}

Here is an example:

const obj = {
    id: 'id at level 1',
    level2: {
      id: 'id at level 2',
      level3: {
        id: 'id at level 3',
        level4: {
          level5: {
            id: 'id at level 5'
          }
       }
    }
  },
  text: ''
}

main(obj, 'id');

following Anton's solution, come up with this ViewHolder which holds/handles/delegates different type of layouts. But not sure if the replacing new layout would work when the recycling view's ViewHolder is not type of the data roll in.

So basically, onCreateViewHolder(ViewGroup parent, int viewType) is only called when new view layout is needed;

getItemViewType(int position) will be called for the viewType;

onBindViewHolder(ViewHolder holder, int position) is always called when recycling the view (new data is brought in and try to display with that ViewHolder).

So when onBindViewHolder is called it needs to put in the right view layout and update the ViewHolder.

Is the way correct to replacing the view layout for that ViewHolder to be brought in, or any problem? Appreciate any comment!

public int getItemViewType(int position) {
    TypedData data = mDataSource.get(position);
    return data.type;

Edit: ViewHolder has member mItemViewType to hold the view

Edit: looks like in onBindViewHolder(ViewHolder holder, int position) the ViewHolder passed in has been picked up (or created) by looked at getItemViewType(int position) to make sure it is a match, so may not need to worry there that ViewHolder's type does not match the data[position]'s type. Does anyone knows more how the ViewHolder in the onBindViewHolder() is picked up?

Edit: Looks like The recycle ViewHolder is picked by type, so no warrior there.

Edit: http://wiresareobsolete.com/2014/09/building-a-recyclerview-layoutmanager-part-1/ answers this question.

It gets the recycle ViewHolder like:

holder = getRecycledViewPool().getRecycledView(mAdapter.getItemViewType(offsetPosition));

or create new one if not find recycle ViewHolder of right type.

public ViewHolder getRecycledView(int viewType) {
        final ArrayList<ViewHolder> scrapHeap = mScrap.get(viewType);
        if (scrapHeap != null && !scrapHeap.isEmpty()) {
            final int index = scrapHeap.size() - 1;
            final ViewHolder scrap = scrapHeap.get(index);
            scrapHeap.remove(index);
            return scrap;
        }
        return null;
    }

View getViewForPosition(int position, boolean dryRun) {
    ......

    if (holder == null) {
            final int offsetPosition = mAdapterHelper.findPositionOffset(position);
            if (offsetPosition < 0 || offsetPosition >= mAdapter.getItemCount()) {
                throw new IndexOutOfBoundsException("Inconsistency detected. Invalid item "
                        + "position " + position + "(offset:" + offsetPosition + ")."
                        + "state:" + mState.getItemCount());
            }

            final int type = mAdapter.getItemViewType(offsetPosition);
            // 2) Find from scrap via stable ids, if exists
            if (mAdapter.hasStableIds()) {
                holder = getScrapViewForId(mAdapter.getItemId(offsetPosition), type, dryRun);
                if (holder != null) {

As others have mentioned in this and other similar threads, the best way to avoid this problem is to use RGBA/HSLA or else use a transparent PNG.

But, if you want a ridiculous solution, similar to the one linked in another answer in this thread (which is also my website), here's a brand new script I wrote that fixes this problem automatically, called thatsNotYoChild.js:

http://www.impressivewebs.com/fixing-parent-child-opacity/

Basically it uses JavaScript to remove all children from the parent div, then reposition the child elements back to where they should be without actually being children of that element anymore.

To me, this should be a last resort, but I thought it would be fun to write something that did this, if anyone wants to do this.

Not sure why they're doing this but, you could get around this by reseting the hash at the top of your page:

if (window.location.hash == "#_=_")
  window.location.hash = "";

The thing is that decimal numbers defaults to double. And since double doesn't fit into float you have to tell explicitely you intentionally define a float. So go with:

float b = 3.6f;

Not exactly an answer to the quoting/escaping problem of the original question but probably something that would actually have been more useful for the op:

unset FILES
for f in 2011-*.jpg; do FILES+=("$f"); done
echo "${FILES[@]}"

Where of course the expression would have to be adopted to the specific requirement (e.g. *.jpg for all or 2001-09-11*.jpg for only the pictures of a certain day).

Try this solution. I have used databinding for binding view. You can use common "findViewById()" function.

public class ActCPExpense extends BaseActivity implements View.OnClickListener,  {
private static final String TAG = ActCPExpense.class.getSimpleName();
private Context mContext;
private ActCpLossBinding mBinding;

    super.onCreate(savedInstanceState);
    try {
        setContentView(R.layout.act_cp_loss);
        mBinding = DataBindingUtil.setContentView(this, R.layout.act_cp_loss);
        mContext = ActCPExpense.this;
        initViewsAct();


    } catch (Exception e) {
        LogUtils.LOGE(TAG, e);
    }

}


private void initViewsAct() {

    adapter.addFragment(FragmentCPPayee.newInstance(), "Title");
    mBinding.viewpager.setAdapter(adapter);
    mBinding.tab.setViewPager(mBinding.viewpager);



}



@Override
public boolean onOptionsItemSelected(MenuItem itemActUtility) {
    int i = itemActUtility.getItemId();
    if (i == android.R.id.home) {

    adapter.removeItem(mBinding.viewpager.getCurrentItem());
    mBinding.tab.setViewPager(mBinding.viewpager);
}

    private final List<Fragment> mFragmentList = new ArrayList<>();
    private final List<String> mFragmentTitleList = new ArrayList<>();

When you don't need some logic or error handling:

• Initialize class fields at declaration

When you need some logic or error handling:

• Initialize class fields in constructor

This works well when the initialization value is available and the initialization can be put on one line. However, this form of initialization has limitations because of its simplicity. If initialization requires some logic (for example, error handling or a for loop to fill a complex array), simple assignment is inadequate. Instance variables can be initialized in constructors, where error handling or other logic can be used.

From https://docs.oracle.com/javase/tutorial/java/javaOO/initial.html .

If you need a more specific text alignment than what adding spaces to the left of the text provides, you can always add a second blank label of exactly how much of an indent you need.

I've got buttons with text aligned left with an indent of 10px and needed a label below to look in line. It gave the label with text and left alignment and put it at x=10 and then made a small second label of the same background color with a width = 10, and lined it up next to the real label.

Minimal code and looks good. Just makes AutoLayout a little more of a hassle to get everything working.

munmap(0xb7d28000, 4096) = 0
write(2, "OSError", 7) = 7

I've seen sloppy code that looks like this:

serrno = errno;
some_Syscall(...)
if (serrno != errno)
/* sound alarm: CATROSTOPHIC ERROR !!! */

You should check to see if this is what is happening in the python code. Errno is only valid if the proceeding system call failed.

Edited to add:

You don't say how long this process lives. Possible consumers of memory

• forked processes
• unused data structures
• shared libraries
• memory mapped files

You can only change the language on the whole server, not individual databases. However if you need to support the UK you can run the following command before all inputs and outputs:

set language 'british english'

Or if you are having issues entering datatimes from your application you might want to consider a universal input type such as

1-Dec-2008

Note that probability is different than probability density pdf(), which some of the previous answers refer to. Probability is the chance that the variable has a specific value, whereas the probability density is the chance that the variable will be near a specific value, meaning probability over a range. So to obtain the probability you need to compute the integral of the probability density function over a given interval. As an approximation, you can simply multiply the probability density by the interval you're interested in and that will give you the actual probability.

import numpy as np
from scipy.stats import norm

data_start = -10
data_end = 10
data_points = 21
data = np.linspace(data_start, data_end, data_points)

point_of_interest = 5
mu = np.mean(data)
sigma = np.std(data)                                   
interval = (data_end - data_start) / (data_points - 1)
probability = norm.pdf(point_of_interest, loc=mu, scale=sigma) * interval

The code above will give you the probability that the variable will have an exact value of 5 in a normal distribution between -10 and 10 with 21 data points (meaning interval is 1). You can play around with a fixed interval value, depending on the results you want to achieve.

newTitle is a local variable where you create the fields. So when that functions ends, the variable newTitle, does not exist anymore. (The JTextField that was referenced by newTitle does still exist however.)

Thus, increase the scope of the variable, so that you can access it another method.

public SomeFrame extends JFrame {
   JTextField myTitle;//can be used anywhere in this class

   creationOfTheFields()
   {
   //other code
      myTitle = new JTextField("spam");  
      myTitle.setBounds(80, 40, 225, 20);
      options.add(myTitle);
   //blabla other code
   }

   private void New_Name()  
   {  
      this.setTitle(myTitle.getText());  
   } 
}

I don't love relying on storage internals (that datetime is a float with whole number = day and fractional = time), but I do the same thing as the answer Jhonny D. Cano. This is the way all of the db devs I know do it. Definitely do not convert to string. If you must avoid processing as float/int, then the best option is to pull out hour/minute/second/milliseconds with DatePart()

Just use as like following ...

<?php
   echo $_SERVER['SERVER_NAME'];
?>

As mentioned in the comments, there cannot be a continuous scale on variable of the factor type. You could change the factor to numeric as follows, just after you define the meltDF variable.

meltDF$variable=as.numeric(levels(meltDF$variable))[meltDF$variable]

Then, execute the ggplot command

  ggplot(meltDF[meltDF$value == 1,]) + geom_point(aes(x = MW, y =   variable)) +
     scale_x_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200)) +
     scale_y_continuous(limits=c(0, 1200), breaks=c(0, 400, 800, 1200))

And you will have your chart.

Hope this helps

If you are using Less and Bootstrap you could write:

.user-select(none);

I ran into the same issue and solved it by downloading api level 20 using sdk manager and changing every string that points to android-L. I did it because I dont have a kitkat device and don't want to use emulator. See the image download the marked one.

Here's my build config:

apply plugin: 'com.android.application'

android {
compileSdkVersion 20//changed this from default
buildToolsVersion "20.0.0"

defaultConfig {
    applicationId "com.example.subash.test"
    minSdkVersion 12//changed this from default
    targetSdkVersion 20//changed this from default
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        runProguard false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
}

Aside from using %, age of empires III to lower case is age of empires iii so your query should be:

select *
from games
where lower(title) like 'age of empires iii%'

For my interactive day-to-day gitting (where I diff the working tree against the HEAD all the time, and would like to have untracked files included in the diff), add -N/--intent-to-add is unusable, because it breaks git stash.

So here's my git diff replacement. It's not a particularly clean solution, but since I really only use it interactively, I'm OK with a hack:

d() {
    if test "$#" = 0; then
        (
            git diff --color
            git ls-files --others --exclude-standard |
                while read -r i; do git diff --color -- /dev/null "$i"; done
        ) | `git config --get core.pager`
    else
        git diff "$@"
    fi
}

Typing just d will include untracked files in the diff (which is what I care about in my workflow), and d args... will behave like regular git diff.

Notes:

• We're using the fact here that git diff is really just individual diffs concatenated, so it's not possible to tell the d output from a "real diff" -- except for the fact that all untracked files get sorted last.
• The only problem with this function is that the output is colorized even when redirected; but I can't be bothered to add logic for that.
• I couldn't find any way to get untracked files included by just assembling a slick argument list for git diff. If someone figures out how to do this, or if maybe a feature gets added to git at some point in the future, please leave a note here!

In addition to Eduard Void answer here's the addValidators method:

declare module '@angular/forms' {
  interface FormControl {
    addValidators(validators: ValidatorFn[]): void;
  }
}

FormControl.prototype.addValidators = function(this: FormControl, validators: ValidatorFn[]) {
  if (!validators || !validators.length) {
    return;
  }

  this.clearValidators();
  this.setValidators( this.validator ? [ this.validator, ...validators ] : validators );
};

Using it you can set validators dynamically:

some_form_control.addValidators([ first_validator, second_validator ]);
some_form_control.addValidators([ third_validator ]);

We don't have any way to add volume in running container, but to achieve this objective you may use the below commands:

Copy files/folders between a container and the local filesystem:

docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH

docker cp [OPTIONS] SRC_PATH CONTAINER:DEST_PATH

For reference see:

https://docs.docker.com/engine/reference/commandline/cp/

Use Do...Loop with Until keyword

num=0
Do Until //certain_condition_to_break_loop
 num=num+1
Loop

This loop will continue to execute, Until the condition becomes true

While...Wend is the old syntax and does not provide feature to break loop! Prefer do while loops

After days trying to find the answer, I finally found

display: table;

There was surprisingly very little information available online about how to actually getting it to work, even here, so on to the "How":

To use this fantastic piece of code, you need to think back to when tables were the only real way to structure HTML, namely the syntax. To get a table with 2 rows and 3 columns, you'd have to do the following:

<table>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
    <tr>
        <td></td>
        <td></td>
        <td></td>
    </tr>
</table>

Similarly to get CSS to do it, you'd use the following:

HTML

<div id="table">
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
    <div class="tr">
        <div class="td"></div>
        <div class="td"></div>
        <div class="td"></div>
    </div>
</div>

CSS

#table{ 
    display: table; 
}
.tr{ 
    display: table-row; 
}
.td{ 
    display: table-cell; }

As you can see in the JSFiddle example below, the divs in the 3rd column have no content, yet are respecting the auto height set by the text in the first 2 columns. WIN!

http://jsfiddle.net/blyzz/1djs97yv/1/

It's worth noting that display: table; does not work in IE6 or 7 (thanks, FelipeAls), so depending on your needs with regards to browser compatibility, this may not be the answer that you are seeking.

Try these steps.

--We are going to edit "etc\profile". The environment variables are to be input at the bottom of the file. Since Ubuntu does not give access to root folder, we will have to use a few commands in the terminal

Step1: Start Terminal. Type in command: gksudo gedit /etc/profile

Step2: The profile text file will open. Enter the environment variables at the bottom of the page........... Eg: export JAVA_HOME=/home/alex/jdk1.6.0_22/bin/java

export PATH=/home/alex/jdk1.6.0_22/bin:$PATH

step3: save and close the file. Check if the environment variables are set by using echo command........ Eg echo $PATH

Yes there is a way to do it.

First declare a class.

//anyfile.ts
export class Custom
{
  name: string, 
  empoloyeeID: number
}

Then in your component import the class

import {Custom} from '../path/to/anyfile.ts'
.....
export class FormComponent implements OnInit {
 name: string;
 empoloyeeID : number;
 empList: Array<Custom> = [];
 constructor() {

 }

 ngOnInit() {
 }
 onEmpCreate(){
   //console.log(this.name,this.empoloyeeID);
   let customObj = new Custom();
   customObj.name = "something";
   customObj.employeeId = 12; 
   this.empList.push(customObj);
   this.name ="";
   this.empoloyeeID = 0; 
 }
}

Another way would be to interfaces read the documentation once - https://www.typescriptlang.org/docs/handbook/interfaces.html

Also checkout this question, it is very interesting - When to use Interface and Model in TypeScript / Angular2

`let element = document.queryselector('id or classname');

element.addeventlistiner('click',()=>{

do work })`

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

function click(){ do work };

How about using an input group to style it on the same line?

Here's the final HTML to use:

<div class="input-group">
    <input type="text" class="form-control" placeholder="Start"/>
    <span class="input-group-addon">-</span>
    <input type="text" class="form-control" placeholder="End"/>
</div>

Which will look like this:

Here's a Stack Snippet Demo:

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.2.0/css/bootstrap.css" rel="stylesheet"/>_x000D_
_x000D_
<div class="input-group">_x000D_
    <input type="text" class="form-control" placeholder="Start"/>_x000D_
    <span class="input-group-addon">-</span>_x000D_
    <input type="text" class="form-control" placeholder="End"/>_x000D_
</div>

I'll leave it as an exercise to the reader to translate it into an asp:textbox element

Is Viewstate turned on?

Edit: Perhaps you should reconsider overriding the rendering function

  protected override void RenderContents(HtmlTextWriter output)
    {
        ddlCountries.RenderControl(output);
        ddlStates.RenderControl(output);
    }

and instead add the dropdownlists to the control and render the control using the default RenderContents.

Edit: See the answer from Dennis which I alluded to in my previous comment:

Controls.Add ( ddlCountries );
Controls.Add ( ddlStates );

You can convert like this.

date = datetime.datetime.strptime('2019-3-16T5-49-52-595Z','%Y-%m-%dT%H-%M-%S-%f%z')
date_time = date.strftime('%Y-%m-%dT%H:%M:%S.%fZ')

If you want to pass Method as parameter, use:

using System;

public void Method1()
{
    CallingMethod(CalledMethod);
}

public void CallingMethod(Action method)
{
    method();   // This will call the method that has been passed as parameter
}

public void CalledMethod()
{
    Console.WriteLine("This method is called by passing parameter");
}

SQL Statement:

 SELECT * FROM employee WHERE employeeName LIKE 'A%';

Result:

4           Ashok            IBM            Delhi   Delhi   11005      India

This worked for me...

    double num = 10025000;
    new DecimalFormat("#,###.##");
    DecimalFormat df = (DecimalFormat) DecimalFormat.getInstance(Locale.GERMAN);
    System.out.println(df.format(num));

.set_title('') can be used to add title to Seaborn Plot

import seaborn as sb
sb.boxplot().set_title('Title')

You should put the print function in your view-details.php file and call it once the file is loaded, by either using

<body onload="window.print()"> 

or

$(document).ready(function () { 
  window.print();

In Eclipse Neon.3, as well as in the new Eclipse Photon (4.8.0), I can resize the font easily with Ctrl + Shift + + and -, without any plugin or special key binding.

At least in Editor Windows (this does not work in other Views like Console, Project Explorer etc).

Here is the example for Swift 3:

var stringToReplace = "This my string"
if let range = stringToReplace.range(of: "my") {
   stringToReplace?.replaceSubrange(range, with: "your")
} 

Check if below are enabled

bz, mbstring, intl, ioncube_loader and Json extension.

I used this and it worked out well for me. If your directory is

"repo" and your project is "hello" copy the project there

cd /path/to/my/repo

Initialize your directory

git init

Stage the project

git add hello

commit the project

git commit

Add configurations using the email and username you are using in Bitbucket

git config --global user.email
git config --global user.name

Add comment to the project

git commit -m 'comment'

push the project now

git push origin master

Check out of the master

git checkout master

Can you update any other record within this table, or is this table heavily used? What I am thinking is that while it is attempting to acquire a lock that it needs to update this record the timeout that was set has timed out. You may be able to increase the time which may help.

Intro and basic Implementation

First up, you're going to need at least a URLStreamHandler. This will actually open the connection to a given URL. Notice that this is simply called Handler; this allows you to specify java -Djava.protocol.handler.pkgs=org.my.protocols and it will automatically be picked up, using the "simple" package name as the supported protocol (in this case "classpath").

Usage

new URL("classpath:org/my/package/resource.extension").openConnection();

Code

package org.my.protocols.classpath;

import java.io.IOException;
import java.net.URL;
import java.net.URLConnection;
import java.net.URLStreamHandler;

/** A {@link URLStreamHandler} that handles resources on the classpath. */
public class Handler extends URLStreamHandler {
    /** The classloader to find resources from. */
    private final ClassLoader classLoader;

    public Handler() {
        this.classLoader = getClass().getClassLoader();
    }

    public Handler(ClassLoader classLoader) {
        this.classLoader = classLoader;
    }

    @Override
    protected URLConnection openConnection(URL u) throws IOException {
        final URL resourceUrl = classLoader.getResource(u.getPath());
        return resourceUrl.openConnection();
    }
}

Launch issues

Workarounds/Enhancements

Manual code Handler specification

If you control the code, you can do

new URL(null, "classpath:some/package/resource.extension", new org.my.protocols.classpath.Handler(ClassLoader.getSystemClassLoader()))

and this will use your handler to open the connection.

But again, this is less than satisfactory, as you don't need a URL to do this - you want to do this because some lib you can't (or don't want to) control wants urls...

JVM Handler registration

The ultimate option is to register a URLStreamHandlerFactory that will handle all urls across the jvm:

package my.org.url;

import java.net.URLStreamHandler;
import java.net.URLStreamHandlerFactory;
import java.util.HashMap;
import java.util.Map;

class ConfigurableStreamHandlerFactory implements URLStreamHandlerFactory {
    private final Map<String, URLStreamHandler> protocolHandlers;

    public ConfigurableStreamHandlerFactory(String protocol, URLStreamHandler urlHandler) {
        protocolHandlers = new HashMap<String, URLStreamHandler>();
        addHandler(protocol, urlHandler);
    }

    public void addHandler(String protocol, URLStreamHandler urlHandler) {
        protocolHandlers.put(protocol, urlHandler);
    }

    public URLStreamHandler createURLStreamHandler(String protocol) {
        return protocolHandlers.get(protocol);
    }
}

To register the handler, call URL.setURLStreamHandlerFactory() with your configured factory. Then do new URL("classpath:org/my/package/resource.extension") like the first example and away you go.

JVM Handler Registration Issue

Note that this method may only be called once per JVM, and note well that Tomcat will use this method to register a JNDI handler (AFAIK). Try Jetty (I will be); at worst, you can use the method first and then it has to work around you!

License

I release this to the public domain, and ask that if you wish to modify that you start a OSS project somewhere and comment here with the details. A better implementation would be to have a URLStreamHandlerFactory that uses ThreadLocals to store URLStreamHandlers for each Thread.currentThread().getContextClassLoader(). I'll even give you my modifications and test classes.

Fragments lives within the Activity and has:

• its own lifecycle
• its own layout
• its own child fragments and etc.

Think of Fragments as a sub activity of the main activity it belongs to, it cannot exist of its own and it can be called/reused again and again. Hope this helps :)

The Pythonic way of summing an array is using sum. For other purposes, you can sometimes use some combination of reduce (from the functools module) and the operator module, e.g.:

def product(xs):
    return reduce(operator.mul, xs, 1)

Be aware that reduce is actually a foldl, in Haskell terms. There is no special syntax to perform folds, there's no builtin foldr, and actually using reduce with non-associative operators is considered bad style.

Using higher-order functions is quite pythonic; it makes good use of Python's principle that everything is an object, including functions and classes. You are right that lambdas are frowned upon by some Pythonistas, but mostly because they tend not to be very readable when they get complex.

I have tried several solutions mentioned over web, unfortunately without any success. In my project, I have two interfaces(xml/json) for each service. Adding mex endpoints or binding configurations did not helped at all. But, I have noticed, I get this error only when running project with *.svc.cs or *.config file focused. When I run project with IService.cs file focused (where interfaces are defined), service is added without any errors. This is really strange and in my opinion conclusion is bug in Visual Studio 2013. I reproduced same behaviour on several machines(even on Windows Server machine). Hope this helps someone.

EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245

To see exactly what is happening, use nc -l and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:

nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000

You can do multiple tests with:

while true; do printf '' | nc -l localhost 8000; done

Mozilla Developer Network's Guide to Regular Expressions provides this escaping function:

function escapeRegExp(string) {
  return string.replace(/[.*+?^${}()|[\]\\]/g, '\\$&'); // $& means the whole matched string
}

Just remove

[tabBarController presentModalViewController:viewController animated:YES];

and keep

[self dismissModalViewControllerAnimated:YES];

Streams are EventEmitters so you can listen to certain events. As you said there is a finish event for request (previously end).

 var stream = request(...).pipe(...);
 stream.on('finish', function () { ... });

For more information about which events are available you can check the stream documentation page.

CHARINDEX() searches for a substring within a larger string, and returns the position of the match, or 0 if no match is found

if CHARINDEX('ME',@mainString) > 0
begin
    --do something
end

Edit or from daniels answer, if you're wanting to find a word (and not subcomponents of words), your CHARINDEX call would look like:

CHARINDEX(' ME ',' ' + REPLACE(REPLACE(@mainString,',',' '),'.',' ') + ' ')

(Add more recursive REPLACE() calls for any other punctuation that may occur)

Create a separate table using into statement For example

Select * into Test_123 from [dbo].[Employee] where Name like '%Test%'

Go to the Database Right Click the Database Click on Generate Script Select your table Select advanace option and select the Attribute "Data Only" Select the file "open in new query"

Sql will generate script for you

Ugh, this is an old problem, something that still pops up in Visual Studio once in a while. It's bitten me a couple of times and I've lost hours restarting and fighting with VS. I'm sure it's been discussed here on SO more than once. It's also been talked about on the MSDN forums. There isn't an actual solution, but there are a couple of workarounds. Start researching here.

What's happening is that VS is acquiring a lock on a file and then not releasing it. Ironically, that lock prevents VS itself from deleting the file so that it can recreate it when you rebuild the application. The only apparent solution is to close and restart VS so that it will release the lock on the file.

My original workaround was opening up the bin/Debug folder and renaming the executable. You can't delete it if it's locked, but you can rename it. So you can just add a number to the end or something, which allows you to keep working without having to close all of your windows and wait for VS to restart. Some people have even automated this using a pre-build event to append a random string to the end of the old output filename. Yes, this is a giant hack, but this problem gets so frustrating and debilitating that you'll do anything.

I've later learned, after a bit more experimentation, that the problem seems to only crop up when you build the project with one of the designers open. So, the solution that has worked for me long term and prevented me from ever dealing with one of those silly errors again is making sure that I always close all designer windows before building a WinForms project. Yes, this too is somewhat inconvenient, but it sure beats the pants off having to restart VS twice an hour or more.

I assume this applies to WPF, too, although I don't use it and haven't personally experienced the problem there.

I also haven't yet tried reproducing it on VS 2012 RC. I don't know if it's been fixed there yet or not. But my experience so far has been that it still manages to pop up even after Microsoft has claimed to have fixed it. It's still there in VS 2010 SP1. I'm not saying their programmers are idiots who don't know what they're doing, of course. I figure there are just multiple causes for the bug and/or that it's very difficult to reproduce reliably in a laboratory. That's the same reason I haven't personally filed any bug reports on it (although I've +1'ed other peoples), because I can't seem to reliably reproduce it, rather like the Abominable Snowman.

If you only want to read the first 999,999 (non-header) rows:

read_csv(..., nrows=999999)

If you only want to read rows 1,000,000 ... 1,999,999

read_csv(..., skiprows=1000000, nrows=999999)

nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*

skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file

and for large files, you'll probably also want to use chunksize:

chunksize : int, default None Return TextFileReader object for iteration

I built a tool for meta generation. It pre-configures entries for Facebook, Google+ and Twitter, and you can use it free here: http://www.groovymeta.com

To answer the question a bit more, OG tags (Open Graph) tags work similarly to meta tags, and should be placed in the HEAD section of your HTML file. See Facebook's best practises for more information on how to use OG tags effectively.

With the new version of HttpClient and without the WebApi package it would be:

var content = new StringContent(jsonObject.ToString(), Encoding.UTF8, "application/json");
var result = client.PostAsync(url, content).Result;

Or if you want it async:

var result = await client.PostAsync(url, content);

No, but you can provide your own counter.

The reason for this is that the for-each loop internally does not have a counter; it is based on the Iterable interface, i.e. it uses an Iterator to loop through the "collection" - which may not be a collection at all, and may in fact be something not at all based on indexes (such as a linked list).

Smart pointers will clean themselves up after they go out of scope (thereby removing fear of most memory leaks). Shared pointers are smart pointers that keep a count of how many instances of the pointer exist, and only clean up the memory when the count reaches zero. In general, only use shared pointers (but be sure to use the correct kind--there is a different one for arrays). They have a lot to do with RAII.

MySQL has discontinued drop database command from mysql client shell. Need to use mysqladmin to drop a database.

For question 1:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C2 = b.C2 AND a.C3 = b.C3 AND a.C4 = b.C4

Using an inner join is much more efficient than a subquery because it requires fewer operations, and maintains the use of indexes when comparing the values, allowing the SQL server to better optimize the query before its run. Using appropriate indexes with this query can bring your query down to only n * log(n) rows to compare.

Using a subquery with your where clause or only doing a standard join where C1 does not equal C2 results in a table that has roughly 2 to the power of n rows to compare, where n is the number of rows in the table.

So by using proper indexing with an Inner Join, which only returns records which met the join criteria, we're able to drastically improve the performance. Also note that we return DISTINCT a.*, because this will only return the columns for table a where the join criteria was met. Returning * would return the columns for both a and b where the criteria was met, and not including DISTINCT would result in a duplicate of each row for each time that row row matched another row more than once.

A similar approach could also be performed using CROSS APPLY, which still uses a subquery, but makes use of indexes more efficiently.

An implementation with the keyword USING instead of ON could also work, but the syntax is more complicated to make work because your want to match on rows where C1 does not match, so you would need an additional where clause to filter out matching each row with itself. Also, USING is not compatible/allowed in conjunction with table values in all implementations of SQL, so it's best to stick with ON.

Similarly, for question 2:

SELECT DISTINCT a.*
  FROM [Table] a
  INNER JOIN
  [Table] b
  ON
  a.C1 <> b.C1 AND a.C4 = b.C4

This is essentially the same query as for 1, but because it only wants to know which rows match for C4, we only compare on the rows for C4.

Instead of using a PreferenceActivity to directly load preferences, use an AppCompatActivity or equivalent that loads a PreferenceFragmentCompat that loads your preferences. It's part of the support library (now Android Jetpack) and provides compatibility back to API 14.

In your build.gradle, add a dependency for the preference support library:

dependencies {
    // ...
    implementation "androidx.preference:preference:1.0.0-alpha1"
}

Note: We're going to assume you have your preferences XML already created.

For your activity, create a new activity class. If you're using material themes, you should extend an AppCompatActivity, but you can be flexible with this:

public class MyPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_preferences_activity)
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, MyPreferencesFragment())
                    .commitNow()
        }
    }
}

Now for the important part: create a fragment that loads your preferences from XML:

public class MyPreferencesFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.my_preferences_fragment); // Your preferences fragment
    }
}

For more information, read the Android Developers docs for PreferenceFragmentCompat.

use of bundle send data from one activity to another activity with the help of intent object; Bundle hold the data that can be any type.

Now I tell that how to create bundle passing data between two activity.

Step 1: On First activity

Bundle b=new Bundle();

b.putString("mkv",anystring);

Intent in=new Intent(getApplicationContext(),secondActivity.class);

in.putExtras(b);

startActivity(in);

Step 2: On Second Activity

Intent in=getIntent();

Bundle b=in.getExtras();

String s=b.getString("mkv");

I think this is useful for you...........

You can use ng-change instead of ng-click:

<!doctype html>
<html>
<head>
  <script src="http://code.angularjs.org/1.2.3/angular.min.js"></script>
  <script>
        var app = angular.module('myapp', []);
        app.controller('mainController', function($scope) {
          $scope.vm = {};
          $scope.vm.myClick = function($event) {
                alert($event);
          }
        });     
  </script>  
</head>
<body ng-app="myapp">
  <div ng-controller="mainController">
    <input type="checkbox" ng-model="vm.myChkModel" ng-change="vm.myClick(vm.myChkModel)">
  </div>
</body>
</html>

You can try something like this:

Inside customview constructor:

mContext = context;

Next inside customview you can call:

((MainActivity) mContext).updateText( text );

Inside MainAcivity define:

public void updateText(final String text) {

     TextView txtView = (TextView) findViewById(R.id.text);
     txtView.setText(text);
}

It works for me.

For you to output foo {1, 2, 3} you have to do something like:

string t = "1, 2, 3";
string v = String.Format(" foo {{{0}}}", t);

To output a { you use {{ and to output a } you use }}.

or Now, you can also use c# string interpolation like this (feature available in C# 6.0)

Escaping Brackets: String Interpolation $(""). it is new feature in C# 6.0

var inVal = "1, 2, 3";
var outVal = $" foo {{{inVal}}}";
//Output will be:  foo {1, 2, 3}

I had the same problem. You want to look the connection object supplied by the entity manager:

$conn = $em->getConnection();

You can then query/execute directly against it:

$statement = $conn->query('select foo from bar');
$num_rows_effected = $conn->exec('update bar set foo=1');

See the docs for the connection object at http://www.doctrine-project.org/api/dbal/2.0/doctrine/dbal/connection.html

Sadly git is so unrelable :( I just lost 2 days of work :(

It's best to manual backup anything before doing commit. I just did "git commit" and git just destroy all my changes without saying anything.

I learned my lesson - next time backup first and only then commit. Never trust git for anything.

Yes, there is std::byte (defined in <cstddef>).

C++ 17 introduced it.

Pickle serializes a single object at a time, and reads back a single object - the pickled data is recorded in sequence on the file.

If you simply do pickle.load you should be reading the first object serialized into the file (not the last one as you've written).

After unserializing the first object, the file-pointer is at the beggining of the next object - if you simply call pickle.load again, it will read that next object - do that until the end of the file.

objects = []
with (open("myfile", "rb")) as openfile:
    while True:
        try:
            objects.append(pickle.load(openfile))
        except EOFError:
            break

Kotlin

startActivity(Intent(Intent.ACTION_VIEW).apply {
            data = Uri.parse(your_link)
        })

According to the documentation Checks the existence of files in the specified order and uses the first found file for request processing; the processing is performed in the current context. The path to a file is constructed from the file parameter according to the root and alias directives. It is possible to check directory’s existence by specifying a slash at the end of a name, e.g. “$uri/”. If none of the files were found, an internal redirect to the uri specified in the last parameter is made. Important

an internal redirect to the uri specified in the last parameter is made.

So in last parameter you should add your page or code if first two parameters returns false.

location / {
  try_files $uri $uri/index.html index.html;
}

My issue is a little different, I need to switch from one childViewController in 1st tabBar to home viewController of 2nd tabBar. I simply use the solution provided in the upstairs:

tabBarController.selectedIndex = 2

However when it switched to the home page of 2nd tabBar, the content is invisible. And when I debug, viewDidAppear, viewWillAppear, viewDidLoad, none of them is called. My solutions is to add the following code in the UITabBarController:

override var shouldAutomaticallyForwardAppearanceMethods: Bool 
{
    return true
}

Apart from changing to SSH you can also keep using HTTPS, if you don't mind to put your password in clear text. Put this in your ~/.netrc and it won't ask for your username/password (at least on Linux and Mac):

machine github.com
       login <user>
       password <password>

Addition (see VonC's second comment): on Windows the file name is %HOME%\_netrc.

Also read VonC's first comment in case you want to encrypt.

Another addition (see user137717's comment) which you can use if you have Git 1.7.10 or newer.

Cache your GitHub password in Git using a credential helper:

If you're cloning GitHub repositories using HTTPS, you can use a credential helper to tell Git to remember your GitHub username and password every time it talks to GitHub.

This also works on Linux, Mac, and Windows.

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

The solution of Jacek Milewski works for me and, based on his solution, if you need and inversed triangle you can use this:

<?xml version="1.0" encoding="utf-8"?>

            android:toDegrees="45"
            android:pivotX="135%" 
            android:pivotY="15%">

E:>move "blogger code.txt" d:/"blogger code.txt"

    1 file(s) moved.

"blogger code.txt" is a file name

The file move from E: drive to D: drive

Following on from @Wilf's answer, I was trying to import a spreadsheet which had spaces in one of the headings, which I eliminated. I checked for leading and trailing spaces, but still had the same problem - until I used Ctrl-Right from the last real heading cell, and found another cell on the first row that looked blank but obviously contained some whitespace. After deleting this, my import works. Thanks for the pointers :)

Untested...

Another thing that can produce this error is when you are setting something equal to the return from a function, but forgot to actually return anything.

Example:

def foo(dict_of_dicts):
    for key, row in dict_of_dicts.items():
        for key, inner_row in row.items():
            Do SomeThing
    #Whoops, forgot to return all my stuff

return1, return2, return3 = foo(dict_of_dicts)

This is a little bit of a tough error to spot because the error can also be produced if the row variable happens to be None on one of the iterations. The way to spot it is that the trace fails on the last line and not inside the function.

If your only returning one variable from a function, I am not sure if the error would be produced... I suspect error "'NoneType' object is not iterable in Python" in this case is actually implying "Hey, I'm trying to iterate over the return values to assign them to these three variables in order but I'm only getting None to iterate over"

The best method that I know of and probably the simplest is to use the Windows Task Scheduler to execute your code at a specific time of day or have you application run permanently and check for a particular time of day or write a windows service that does the same.
