To check your MySQL version on your mac, navigate to the directory where you installed it (default is usr/local/mysql/bin) and issue this command:

./mysql --version

Alternatively, to avoid needing to navigate to that specific dir to run the command, add its location to your path ($PATH). There's more than one way to add a dir to your $PATH (with explanations on stackoverflow and other places on how to do so), such as adding it to your ./bash_profile.

After adding the mysql bin dir to your $PATH, verify it's there by executing:

echo $PATH

Thereafter you can check your mysql version from anywhere by running (note no "./"):

mysql --version

Print a Timestamp in java, using the java.sql.Timestamp.

import java.sql.Timestamp;
import java.util.Date;

public class GetCurrentTimeStamp {
    public static void main( String[] args ){
        java.util.Date date= new java.util.Date();
        System.out.println(new Timestamp(date.getTime()));
    }
}

This prints:

2014-08-07 17:34:16.664

Print a Timestamp in Java using SimpleDateFormat on a one-liner.

import java.util.Date;
import java.text.SimpleDateFormat;

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

        System.out.println(
            new SimpleDateFormat("MM/dd/yyyy HH:mm:ss").format(new Date()));

    }

}

Prints:

08/14/2014 14:10:38

assertTrue will fail if the checked value is false, and assertFalse will do the opposite: fail if the checked value is true.

Another thing, your last assertEquals will very likely fail, as it will compare the "Book was already checked out" string with the output of m1.checkOut(b1,p2). It needs a third parameter (the second value to check for equality).

Can you use date as a factor?

Yes, but you probably shouldn't.

...or should you use as.Date on a date column?

Yes.

Which leads us to this:

library(scales)
df$Month <- as.Date(df$Month)
ggplot(df, aes(x = Month, y = AvgVisits)) + 
  geom_bar(stat = "identity") +
  theme_bw() +
  labs(x = "Month", y = "Average Visits per User") +
  scale_x_date(labels = date_format("%m-%Y"))

in which I've added stat = "identity" to your geom_bar call.

In addition, the message about the binwidth wasn't an error. An error will actually say "Error" in it, and similarly a warning will always say "Warning" in it. Otherwise it's just a message.

use ROUND () (See examples ) function in sql server

select round(11.6,0)

result:

12.0

ex2:

select round(11.4,0)

result:

11.0

if you don't want the decimal part, you could do

select cast(round(11.6,0) as int)

This did wonders for me:

dataGridView1.AutoResizeColumns(DataGridViewAutoSizeColumnsMode.AllCells);

Personally I like the navigationDrawer in Google Drive official app. It just works and works great. I agree that the navigation drawer shouldn't move the action bar because is the key point to open and close the navigation drawer.

If you are still trying to get that behavior I recently create a project Called SherlockNavigationDrawer and as you may expect is the implementation of the Navigation Drawer with ActionBarSherlock and works for pre Honeycomb devices. Check it:

David Crawshaw project(sqlitejdbc-v056.jar) seems out of date and last update was Jun 20, 2009, source here

I would recomend Xerials fork of Crawshaw sqlite wrapper. I replaced sqlitejdbc-v056.jar with Xerials sqlite-jdbc-3.7.2.jar file without any problem.

Uses same syntax as in Bernie's answer and is much faster and with latest sqlite library.

What is different from Zentus's SQLite JDBC?

The original Zentus's SQLite JDBC driver http://www.zentus.com/sqlitejdbc/ itself is an excellent utility for using SQLite databases from Java language, and our SQLiteJDBC library also relies on its implementation. However, its pure-java version, which totally translates c/c++ codes of SQLite into Java, is significantly slower compared to its native version, which uses SQLite binaries compiled for each OS (win, mac, linux).

To use the native version of sqlite-jdbc, user had to set a path to the native codes (dll, jnilib, so files, which are JNDI C programs) by using command-line arguments, e.g., -Djava.library.path=(path to the dll, jnilib, etc.), or -Dorg.sqlite.lib.path, etc. This process was error-prone and bothersome to tell every user to set these variables. Our SQLiteJDBC library completely does away these inconveniences.

Another difference is that we are keeping this SQLiteJDBC libray up-to-date to the newest version of SQLite engine, because we are one of the hottest users of this library. For example, SQLite JDBC is a core component of UTGB (University of Tokyo Genome Browser) Toolkit, which is our utility to create personalized genome browsers.

EDIT : As usual when you update something, there will be problems in some obscure place in your code(happened to me). Test test test =)

In addition to the POSIX conformant syntax used in this answer,

basename string [suffix]

as in

basename /foo/fizzbuzz.bar .bar

GNU basename supports another syntax:

basename -s .bar /foo/fizzbuzz.bar

with the same result. The difference and advantage is that -s implies -a, which supports multiple arguments:

$ basename -s .bar /foo/fizzbuzz.bar /baz/foobar.bar
fizzbuzz
foobar

This can even be made filename-safe by separating the output with NUL bytes using the -z option, for example for these files containing blanks, newlines and glob characters (quoted by ls):

$ ls has*
'has'$'\n''newline.bar'  'has space.bar'  'has*.bar'

Reading into an array:

$ readarray -d $'\0' arr < <(basename -zs .bar has*)
$ declare -p arr
declare -a arr=([0]=$'has\nnewline' [1]="has space" [2]="has*")

readarray -d requires Bash 4.4 or newer. For older versions, we have to loop:

while IFS= read -r -d '' fname; do arr+=("$fname"); done < <(basename -zs .bar has*)

I believe the modern way to go is place-items: center in the parent container

An example can be found here: https://1linelayouts.glitch.me

If you put all your values in an array, at least you can use string.Join.

string[] myValues = new string[] { ... };
string csvString = string.Join(",", myValues);

You can also use the overload of string.Join that takes params string as the second parameter like this:

string csvString = string.Join(",", value1, value2, value3, ...);

I slightly modified the printer example to make it more explainable

1 document which had 2 pages content was sent to printer

Transaction - document sent to printer

• atomicity - printer prints 2 pages of a document or none
• consistency - printer prints half page and the page gets stuck. The printer restarts itself and prints 2 pages with all content
• isolation - while there were too many print outs in progress - printer prints the right content of the document
• durability - while printing, there was a power cut- printer again prints documents without any errors

Hope this helps someone to get the hang of the concept of ACID

your fadeIn() function calls the fadeOut() function, which calls the fadeIn() function again. the recursion is in the JS.

I faced the same issue. Though in my case I was trying to connect my desktop application to a remote db. So for me, all the above didn't work. I solve this problem by just adding the port (as 128.02.39.29:3315) and it magically works! The reason why I didn't bother to add the port in the first place is because I used same approach (without the port) in another desktop app and it worked. So I hope this might help someone as well.

My understanding is that adding r+ opens for both read and write (just like w+, though as pointed out in the comment, will truncate the file). The b just opens it in binary mode, which is supposed to be less aware of things like line separators (at least in C++).

you can use val function to collect data from inputs:

jQuery("#myInput1").val();

http://api.jquery.com/val/

For future viewers, there is a line in my /etc/nanorc file close to line 153 that says "set tabsize 8". The word might need to be tabsize instead of tabspace. After I replaced 8 with 4 and uncommented the line, it solved my problem.

Very simple you have to just put
\n where ever you want to break line in your string resource.

For example

String s = my string resource have \n line break here;

Careful with rewriting URLs, though. I'm using this, so it keeps URLs rewritten.

Response.Redirect(Request.RawUrl);

CASE WHEN B.[STAT] IS NULL THEN (C.[EVENT DATE]+10)   -- Type DATETIME
     ELSE '-'                                         -- Type VARCHAR
     END AS [DATE]

You need to select one type or the other for the field, the field type can't vary by row. The simplest is to remove the ELSE '-' and let it implicitly get the value NULL instead for the second case.

I had to go through a bit more to force a refresh in VS 2008.

First, there is a Data Sources pane/toolbox (menu trail = Data > Show Data Sources), and a Report Data Sources dialog (menu trail = Report > Data Sources). I had trouble with the Data Sources pane reverting to an earlier property list every time I opened a certain report; it was as if the report designer was overwriting the data definition with the report's cached version thereof.

To remedy this, I had to:

1. Exclude the report from my project to stop the build errors
2. Clean & rebuild my project
3. Refresh the Data Sources pane & confirm I could see the new fields
4. Re-include the report and open the report designer with the Data Sources pane pinned in view
5. (This is the key) Drag one of the new fields anywhere onto the report surface

Number 5 forced the report's internal XML copy of the data definition to refresh. Immediately after that, I could build again.

here is the split function that u asked

CREATE FUNCTION [dbo].[split](
          @delimited NVARCHAR(MAX),
          @delimiter NVARCHAR(100)
        ) RETURNS @t TABLE (id INT IDENTITY(1,1), val NVARCHAR(MAX))
        AS
        BEGIN
          DECLARE @xml XML
          SET @xml = N'<t>' + REPLACE(@delimited,@delimiter,'</t><t>') + '</t>'

          INSERT INTO @t(val)
          SELECT  r.value('.','varchar(MAX)') as item
          FROM  @xml.nodes('/t') as records(r)
          RETURN
        END

execute the function like this

select * from dbo.split('1,2,3,4,5,6,7,8,9,10,11,12,13,14,15',',')

You should not execute resource intensive tasks in the main thread. It will make the UI unresponsive and you will get an ANR. It seems like you will be doing resource intensive stuff and want the user to see the ProgressDialog. You can take a look at http://developer.android.com/reference/android/os/AsyncTask.html to do resource intensive tasks. It also shows you how to use a ProgressDialog.

You should consider svcutil (svcutil question)

Both xsd.exe and svcutil operate on the XML schema file (.xsd). Your XML must conform to a schema file to be used by either of these two tools.

Note that various 3rd party tools also exist for this.

Probably you can implement generic static lookup method.

Like so

public class LookupUtil {
   public static <E extends Enum<E>> E lookup(Class<E> e, String id) {   
      try {          
         E result = Enum.valueOf(e, id);
      } catch (IllegalArgumentException e) {
         // log error or something here

         throw new RuntimeException(
           "Invalid value for enum " + e.getSimpleName() + ": " + id);
      }

      return result;
   }
}

Then you can

public enum MyEnum {
   static public MyEnum lookup(String id) {
       return LookupUtil.lookup(MyEnum.class, id);
   }
}

or call explicitly utility class lookup method.

I also got this error i tried with onPreparedListener but still got this error. Finally i got the solution that error is my fault because i forgot the internet permission in Android Manifest xml. :)

<uses-permission android:name="android.permission.INTERNET" />

I used sample coding for mediaplayer. I used in StreamService.java
onCreate method

String url = "http://s17.myradiostream.com:11474/";
mediaPlayer = new MediaPlayer();            
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource(url);
mediaPlayer.prepare();

I have had this problem on multiple projects converting Excel 2000 to 2010. Here is what I found which seems to be working. I made two changes, but not sure which caused the success:

1) I changed how I closed and saved the file (from close & save = true to save as the same file name and close the file:

...
    Dim oFile           As Object       ' File being processed
...
[Where the error happens - where aArray(i) is just the name of an Excel.xlsb file]
   Set oFile = GetObject(aArray(i))
...
'oFile.Close SaveChanges:=True    - OLD CODE WHICH ERROR'D
'New Code
oFile.SaveAs Filename:=oFile.Name
oFile.Close SaveChanges:=False

2) I went back and looked for all of the .range in the code and made sure it was the full construct..

Application.Workbooks("workbook name").Worksheets("worksheet name").Range("G19").Value

or (not 100% sure if this is correct syntax, but this is the 'effort' i made)

ActiveSheet.Range("A1").Select

The change event only fires after the input loses focus (and was changed).

Be careful when using the isa function. This will be true if your object is of the specified type or one of its subclasses. You have to use strcmp with the class function to test if the object is specifically that type and not a subclass.

This is the code I use for the task:

// `activity` is an instance of Activity class.
Display display = activity.getWindowManager().getDefaultDisplay();
Point screen = new Point();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
    display.getSize(screen);
} else {            
    screen.x = display.getWidth();
    screen.y = display.getHeight();
}

Seems clean enough and yet, takes care of the deprecation.

  SELECT t1.a, t2.b
  FROM t1
  JOIN t2 ON t1.a LIKE '%'+t2.b +'%'

because the last answer not work

you can also use a meta tag to redirect to another url.

It's A Script Write Copy then write in your script file and change your requered field and get out put

DECLARE @Sdate DATETIME, @Edate DATETIME, @Timediff VARCHAR(100)
SELECT @Sdate = '02/12/2014 08:40:18.000',@Edate='02/13/2014 09:52:48.000'
SET @Timediff=DATEDIFF(s, @Sdate, @Edate)

well I wouldn't have expected it, but Halim's SELECT distinct TOP 10 MyId FROM sometable

is functionally identical to Vaishnavi Kumar's select top 10 p.id from(select distinct p.id from tablename)tablename

create table #names ([name] varchar(10))
insert into #names ([name]) values ('jim')
insert into #names ([name]) values ('jim')
insert into #names ([name]) values ('bob')
insert into #names ([name]) values ('mary')
insert into #names ([name]) values ('bob')
insert into #names ([name]) values ('mary')
insert into #names ([name]) values ('john')
insert into #names ([name]) values ('mark')
insert into #names ([name]) values ('matthew')
insert into #names ([name]) values ('luke')
insert into #names ([name]) values ('peter')

select distinct top 5 [name] from #names

select top 5 * from (select distinct [name] from #names) subquery 

drop table #names

produces the same results for both selects:

    name
1   bob
2   jim
3   john
4   luke
5   mark

it's curious that select top 5 distinct is not valid, but select distinct top 5 is and works as you might expect select top 5 distinct to work.

So you can do this

$('#textarea').attr('enable',false)

try it and give feedback

The below code always gives the public IP of the client (and not a private IP behind a proxy).

from flask import request

if request.environ.get('HTTP_X_FORWARDED_FOR') is None:
    print(request.environ['REMOTE_ADDR'])
else:
    print(request.environ['HTTP_X_FORWARDED_FOR']) # if behind a proxy

This is my 2 cents based on Grax's answer, but with two parameters required for a generic method.

Assume your method is defined as follows in an Helpers class:

public class Helpers
{
    public static U ConvertCsvDataToCollection<U, T>(string csvData)
    where U : ObservableCollection<T>
    {
      //transform code here
    }
}

In my case, U type is always an observable collection storing object of type T.

As I have my types predefined, I first create the "dummy" objects that represent the observable collection (U) and the object stored in it (T) and that will be used below to get their type when calling the Make

object myCollection = Activator.CreateInstance(collectionType);
object myoObject = Activator.CreateInstance(objectType);

Then call the GetMethod to find your Generic function:

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

So far, the above call is pretty much identical as to what was explained above but with a small difference when you need have to pass multiple parameters to it.

You need to pass an Type[] array to the MakeGenericMethod function that contains the "dummy" objects' types that were create above:

MethodInfo generic = method.MakeGenericMethod(
new Type[] {
   myCollection.GetType(),
   myObject.GetType()
});

Once that's done, you need to call the Invoke method as mentioned above.

generic.Invoke(null, new object[] { csvData });

And you're done. Works a charm!

UPDATE:

As @Bevan highlighted, I do not need to create an array when calling the MakeGenericMethod function as it takes in params and I do not need to create an object in order to get the types as I can just pass the types directly to this function. In my case, since I have the types predefined in another class, I simply changed my code to:

object myCollection = null;

MethodInfo method = typeof(Helpers).
GetMethod("ConvertCsvDataToCollection");

MethodInfo generic = method.MakeGenericMethod(
   myClassInfo.CollectionType,
   myClassInfo.ObjectType
);

myCollection = generic.Invoke(null, new object[] { csvData });

myClassInfo contains 2 properties of type Type which I set at run time based on an enum value passed to the constructor and will provide me with the relevant types which I then use in the MakeGenericMethod.

Thanks again for highlighting this @Bevan.

The fileinput module of the Python standard library will rewrite a file inplace if you use the inplace=1 parameter:

import sys
import fileinput

# replace all occurrences of 'sit' with 'SIT' and insert a line after the 5th
for i, line in enumerate(fileinput.input('lorem_ipsum.txt', inplace=1)):
    sys.stdout.write(line.replace('sit', 'SIT'))  # replace 'sit' and write
    if i == 4: sys.stdout.write('\n')  # write a blank line after the 5th line

Unions are particularly useful in Embedded programming or in situations where direct access to the hardware/memory is needed. Here is a trivial example:

typedef union
{
    struct {
        unsigned char byte1;
        unsigned char byte2;
        unsigned char byte3;
        unsigned char byte4;
    } bytes;
    unsigned int dword;
} HW_Register;
HW_Register reg;

Then you can access the reg as follows:

reg.dword = 0x12345678;
reg.bytes.byte3 = 4;

Endianness (byte order) and processor architecture are of course important.

Another useful feature is the bit modifier:

typedef union
{
    struct {
        unsigned char b1:1;
        unsigned char b2:1;
        unsigned char b3:1;
        unsigned char b4:1;
        unsigned char reserved:4;
    } bits;
    unsigned char byte;
} HW_RegisterB;
HW_RegisterB reg;

With this code you can access directly a single bit in the register/memory address:

x = reg.bits.b2;

Same answer as here.

If you want a non-regex ASCII A-z 0-9 check, you cannot use char.IsLetterOrDigit() as that includes other Unicode characters.

What you can do is check the character code ranges.

• 48 -> 57 are numerics
• 65 -> 90 are capital letters
• 97 -> 122 are lower case letters

The following is a bit more verbose, but it's for ease of understanding rather than for code golf.

    public static bool IsAsciiAlphaNumeric(this string str)
    {
        if (string.IsNullOrEmpty(str))
        {
            return false;
        }

        for (int i = 0; i < str.Length; i++)
        {
            if (str[i] < 48) // Numeric are 48 -> 57
            {
                return false;
            }

            if (str[i] > 57 && str[i] < 65) // Capitals are 65 -> 90
            {
                return false;
            }

            if (str[i] > 90 && str[i] < 97) // Lowers are 97 -> 122
            {
                return false;
            }

            if (str[i] > 122)
            {
                return false;
            }
        }

        return true;
    }

The simplest solution is to go to your XML layout containing your webview. Change your android:layout_width and android:layout_height from "wrap_content" to "match_parent".

  <WebView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/webView"/>

As @KyssTao has been saying, help(dates.num2date) says that the x has to be a float giving the number of days since 0001-01-01 plus one. Hence, 19910102 is not 2/Jan/1991, because if you counted 19910101 days from 0001-01-01 you'd get something in the year 54513 or similar (divide by 365.25, number of days in a year).

Use datestr2num instead (see help(dates.datestr2num)):

new_x = dates.datestr2num(date) # where date is '01/02/1991'

I had this error because I was providing a string of arguments to subprocess.call instead of an array of arguments. To prevent this, use shlex.split:

import shlex, subprocess
command_line = "ls -a"
args = shlex.split(command_line)
p = subprocess.Popen(args)

Check out php.ini the value set for session.gc_maxlifetime is the ID lifetime in seconds.

I believe the default is 1440 seconds (24 mins)

http://www.php.net/manual/en/session.configuration.php

Edit: As some comments point out, the above is not entirely accurate. A wonderful explanation of why, and how to implement session lifetimes is available here:

How do I expire a PHP session after 30 minutes?

Possibly also check the sessionState tag in Web.config

Believe it or not, some projects I've worked on will set a connection string here as well.

Setting this config to:

<sessionState mode="InProc" />

Fixed this issue in my case after checking all other connection strings were correct.

I've found this answer in the site https://plainjs.com/javascript/styles/set-and-get-css-styles-of-elements-53/.

In this code we add multiple styles in an element:

  , cssStyle = (el, styles) => {_x000D_
      for (var property in styles) {_x000D_
          el.style[property] = styles[property];_x000D_
      }_x000D_
  }_x000D_
;_x000D_
_x000D_
cssStyle(element, { background:'tomato', color: 'white', padding: '0.5rem 1rem'});

1) show popup with form

2) submit form using AJAX

3) in AJAX server side code, render response that will either:

• show popup with form with validations or just a message
• close the popup (and maybe redirect you to new page)

How about:

<table>
  <tr ng-repeat="(key, value) in data">
    <td> {{key}} </td> <td> {{ value }} </td>
  </tr>
</table>

This method is listed in the docs: https://docs.angularjs.org/api/ng/directive/ngRepeat

Not in VB.NET, you have to select all lines at then Edit, Advanced, Comment Selection menu, or a keyboard shortcut for that menu.

you could do so:

<button onclick="location.href='page'">

you could change the action attribute of the form on click the button:

<button class="float-left submit-button" onclick='myFun()'>Home</button>

<script>
myFun(){
$('form').attr('action','new path');
}
</script>

hash_map was a common extension provided by many library implementations. That is exactly why it was renamed to unordered_map when it was added to the C++ standard as part of TR1. map is generally implemented with a balanced binary tree like a red-black tree (implementations vary of course). hash_map and unordered_map are generally implemented with hash tables. Thus the order is not maintained. unordered_map insert/delete/query will be O(1) (constant time) where map will be O(log n) where n is the number of items in the data structure. So unordered_map is faster, and if you don't care about the order of the items should be preferred over map. Sometimes you want to maintain order (ordered by the key) and for that map would be the choice.

Another example if you are using Titanium Alloy:

 collection.fetch({ 
     data: {
             where : JSON.stringify({
                page: 1
             })
           } 
      });

object.__del__(self) is called when the instance is about to be destroyed.

>>> class Test:
...     def __del__(self):
...         print "deleted"
... 
>>> test = Test()
>>> del test
deleted

Object is not deleted unless all of its references are removed(As quoted by ethan)

Also, From Python official doc reference:

del x doesn’t directly call x.del() — the former decrements the reference count for x by one, and the latter is only called when x‘s reference count reaches zero

If I understand the goal is to insert a new record to a table but if the data is already on the table: skip it! Here is my answer:

INSERT INTO tbl_member 
(Field1,Field2,Field3,...) 
SELECT a.Field1,a.Field2,a.Field3,... 
FROM (SELECT Field1 = [NewValueField1], Field2 = [NewValueField2], Field3 = [NewValueField3], ...) AS a 
LEFT JOIN tbl_member AS b 
ON a.Field1 = b.Field1 
WHERE b.Field1 IS NULL

The record to be inserted is in the new value fields.

I wrote a useful scalar function to simulate the TRY_CAST function of SQL SERVER 2012 in SQL Server 2008.

You can see it in the next link below and we help each other to improve it. TRY_CAST Function for SQL Server 2008 https://gist.github.com/jotapardo/800881eba8c5072eb8d99ce6eb74c8bb

The two main differences are that you must pass 3 parameters and you must additionally perform an explicit CONVERT or CAST to the field. However, it is still very useful because it allows you to return a default value if CAST is not performed correctly.

dbo.TRY_CAST(Expression, Data_Type, ReturnValueIfErrorCast)

Example:

SELECT   CASE WHEN dbo.TRY_CAST('6666666166666212', 'INT', DEFAULT) IS NULL   
                        THEN 'Cast failed'  
                        ELSE 'Cast succeeded'  
                    END AS Result; 

For now only supports the data types INT, DATE, NUMERIC, BIT and FLOAT

I hope you find it useful.

CODE:

DECLARE @strSQL NVARCHAR(1000)
IF NOT EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[dbo].[TRY_CAST]'))
    BEGIN
        SET @strSQL = 'CREATE FUNCTION [dbo].[TRY_CAST] () RETURNS INT AS BEGIN RETURN 0 END'
        EXEC sys.sp_executesql @strSQL
    END

                    Arguments
                    ---------------
                    expression
                    The value to be cast. Any valid expression.

                    Data_Type
                    The data type into which to cast expression.

                    ReturnValueIfErrorCast
                    Value returned if cast fails or is not supported. Required. Set the DEFAULT value by default.


                    Return Type
                    ----------------
                    Returns value cast to SQL_VARIANT type if the cast succeeds; otherwise, returns null if the parameter @pReturnValueIfErrorCast is set to DEFAULT, 
                    or that the user indicates.


                    Remarks
                    ----------------
                    dbo.TRY_CAST function simulates the TRY_CAST function reserved of SQL SERVER 2012 for using in SQL SERVER 2008. 
                    dbo.TRY_CAST function takes the value passed to it and tries to convert it to the specified Data_Type. 
                    If the cast succeeds, dbo.TRY_CAST returns the value as SQL_VARIANT type; if the cast doesn´t succees, null is returned if the parameter @pReturnValueIfErrorCast is set to DEFAULT. 
                    If the Data_Type is unsupported will return @pReturnValueIfErrorCast.
                    dbo.TRY_CAST function requires user make an explicit CAST or CONVERT in ANY statements.
                    This version of dbo.TRY_CAST only supports CAST for INT, DATE, NUMERIC and BIT types.

Check if the deployment target in the General section of the project settings, is greater than that of your device's iOS version.

If yes then you need to update the version of your device to at least the deployment target version. in order for you to be able to install the application on your device.

You will definitely want to start with a good web scraping framework. Later on you may decide that they are too limiting and you can put together your own stack of libraries but without a lot of scraping experience your design will be much worse than pjscrape or scrapy.

Note: I use the terms crawling and scraping basically interchangeable here. This is a copy of my answer to your Quora question, it's pretty long.

Tools

Get very familiar with either Firebug or Chrome dev tools depending on your preferred browser. This will be absolutely necessary as you browse the site you are pulling data from and map out which urls contain the data you are looking for and what data formats make up the responses.

You will need a good working knowledge of HTTP as well as HTML and will probably want to find a decent piece of man in the middle proxy software. You will need to be able to inspect HTTP requests and responses and understand how the cookies and session information and query parameters are being passed around. Fiddler (http://www.telerik.com/fiddler) and Charles Proxy (http://www.charlesproxy.com/) are popular tools. I use mitmproxy (http://mitmproxy.org/) a lot as I'm more of a keyboard guy than a mouse guy.

Some kind of console/shell/REPL type environment where you can try out various pieces of code with instant feedback will be invaluable. Reverse engineering tasks like this are a lot of trial and error so you will want a workflow that makes this easy.

Language

PHP is basically out, it's not well suited for this task and the library/framework support is poor in this area. Python (Scrapy is a great starting point) and Clojure/Clojurescript (incredibly powerful and productive but a big learning curve) are great languages for this problem. Since you would rather not learn a new language and you already know Javascript I would definitely suggest sticking with JS. I have not used pjscrape but it looks quite good from a quick read of their docs. It's well suited and implements an excellent solution to the problem I describe below.

A note on Regular expressions: DO NOT USE REGULAR EXPRESSIONS TO PARSE HTML. A lot of beginners do this because they are already familiar with regexes. It's a huge mistake, use xpath or css selectors to navigate html and only use regular expressions to extract data from actual text inside an html node. This might already be obvious to you, it becomes obvious quickly if you try it but a lot of people waste a lot of time going down this road for some reason. Don't be scared of xpath or css selectors, they are WAY easier to learn than regexes and they were designed to solve this exact problem.

Javascript-heavy sites

In the old days you just had to make an http request and parse the HTML reponse. Now you will almost certainly have to deal with sites that are a mix of standard HTML HTTP request/responses and asynchronous HTTP calls made by the javascript portion of the target site. This is where your proxy software and the network tab of firebug/devtools comes in very handy. The responses to these might be html or they might be json, in rare cases they will be xml or something else.

There are two approaches to this problem:

The low level approach:

You can figure out what ajax urls the site javascript is calling and what those responses look like and make those same requests yourself. So you might pull the html from http://example.com/foobar and extract one piece of data and then have to pull the json response from http://example.com/api/baz?foo=b... to get the other piece of data. You'll need to be aware of passing the correct cookies or session parameters. It's very rare, but occasionally some required parameters for an ajax call will be the result of some crazy calculation done in the site's javascript, reverse engineering this can be annoying.

The embedded browser approach:

Why do you need to work out what data is in html and what data comes in from an ajax call? Managing all that session and cookie data? You don't have to when you browse a site, the browser and the site javascript do that. That's the whole point.

If you just load the page into a headless browser engine like phantomjs it will load the page, run the javascript and tell you when all the ajax calls have completed. You can inject your own javascript if necessary to trigger the appropriate clicks or whatever is necessary to trigger the site javascript to load the appropriate data.

You now have two options, get it to spit out the finished html and parse it or inject some javascript into the page that does your parsing and data formatting and spits the data out (probably in json format). You can freely mix these two options as well.

Which approach is best?

That depends, you will need to be familiar and comfortable with the low level approach for sure. The embedded browser approach works for anything, it will be much easier to implement and will make some of the trickiest problems in scraping disappear. It's also quite a complex piece of machinery that you will need to understand. It's not just HTTP requests and responses, it's requests, embedded browser rendering, site javascript, injected javascript, your own code and 2-way interaction with the embedded browser process.

The embedded browser is also much slower at scale because of the rendering overhead but that will almost certainly not matter unless you are scraping a lot of different domains. Your need to rate limit your requests will make the rendering time completely negligible in the case of a single domain.

Rate Limiting/Bot behaviour

You need to be very aware of this. You need to make requests to your target domains at a reasonable rate. You need to write a well behaved bot when crawling websites, and that means respecting robots.txt and not hammering the server with requests. Mistakes or negligence here is very unethical since this can be considered a denial of service attack. The acceptable rate varies depending on who you ask, 1req/s is the max that the Google crawler runs at but you are not Google and you probably aren't as welcome as Google. Keep it as slow as reasonable. I would suggest 2-5 seconds between each page request.

Identify your requests with a user agent string that identifies your bot and have a webpage for your bot explaining it's purpose. This url goes in the agent string.

You will be easy to block if the site wants to block you. A smart engineer on their end can easily identify bots and a few minutes of work on their end can cause weeks of work changing your scraping code on your end or just make it impossible. If the relationship is antagonistic then a smart engineer at the target site can completely stymie a genius engineer writing a crawler. Scraping code is inherently fragile and this is easily exploited. Something that would provoke this response is almost certainly unethical anyway, so write a well behaved bot and don't worry about this.

Testing

Not a unit/integration test person? Too bad. You will now have to become one. Sites change frequently and you will be changing your code frequently. This is a large part of the challenge.

There are a lot of moving parts involved in scraping a modern website, good test practices will help a lot. Many of the bugs you will encounter while writing this type of code will be the type that just return corrupted data silently. Without good tests to check for regressions you will find out that you've been saving useless corrupted data to your database for a while without noticing. This project will make you very familiar with data validation (find some good libraries to use) and testing. There are not many other problems that combine requiring comprehensive tests and being very difficult to test.

The second part of your tests involve caching and change detection. While writing your code you don't want to be hammering the server for the same page over and over again for no reason. While running your unit tests you want to know if your tests are failing because you broke your code or because the website has been redesigned. Run your unit tests against a cached copy of the urls involved. A caching proxy is very useful here but tricky to configure and use properly.

You also do want to know if the site has changed. If they redesigned the site and your crawler is broken your unit tests will still pass because they are running against a cached copy! You will need either another, smaller set of integration tests that are run infrequently against the live site or good logging and error detection in your crawling code that logs the exact issues, alerts you to the problem and stops crawling. Now you can update your cache, run your unit tests and see what you need to change.

Legal Issues

The law here can be slightly dangerous if you do stupid things. If the law gets involved you are dealing with people who regularly refer to wget and curl as "hacking tools". You don't want this.

The ethical reality of the situation is that there is no difference between using browser software to request a url and look at some data and using your own software to request a url and look at some data. Google is the largest scraping company in the world and they are loved for it. Identifying your bots name in the user agent and being open about the goals and intentions of your web crawler will help here as the law understands what Google is. If you are doing anything shady, like creating fake user accounts or accessing areas of the site that you shouldn't (either "blocked" by robots.txt or because of some kind of authorization exploit) then be aware that you are doing something unethical and the law's ignorance of technology will be extraordinarily dangerous here. It's a ridiculous situation but it's a real one.

It's literally possible to try and build a new search engine on the up and up as an upstanding citizen, make a mistake or have a bug in your software and be seen as a hacker. Not something you want considering the current political reality.

Who am I to write this giant wall of text anyway?

I've written a lot of web crawling related code in my life. I've been doing web related software development for more than a decade as a consultant, employee and startup founder. The early days were writing perl crawlers/scrapers and php websites. When we were embedding hidden iframes loading csv data into webpages to do ajax before Jesse James Garrett named it ajax, before XMLHTTPRequest was an idea. Before jQuery, before json. I'm in my mid-30's, that's apparently considered ancient for this business.

I've written large scale crawling/scraping systems twice, once for a large team at a media company (in Perl) and recently for a small team as the CTO of a search engine startup (in Python/Javascript). I currently work as a consultant, mostly coding in Clojure/Clojurescript (a wonderful expert language in general and has libraries that make crawler/scraper problems a delight)

I've written successful anti-crawling software systems as well. It's remarkably easy to write nigh-unscrapable sites if you want to or to identify and sabotage bots you don't like.

I like writing crawlers, scrapers and parsers more than any other type of software. It's challenging, fun and can be used to create amazing things.

How to Use Sockets in JavaScript/HTML?

There is no facility to use general-purpose sockets in JS or HTML. It would be a security disaster, for one.

There is WebSocket in HTML5. The client side is fairly trivial:

socket= new WebSocket('ws://www.example.com:8000/somesocket');
socket.onopen= function() {
    socket.send('hello');
};
socket.onmessage= function(s) {
    alert('got reply '+s);
};

You will need a specialised socket application on the server-side to take the connections and do something with them; it is not something you would normally be doing from a web server's scripting interface. However it is a relatively simple protocol; my noddy Python SocketServer-based endpoint was only a couple of pages of code.

In any case, it doesn't really exist, yet. Neither the JavaScript-side spec nor the network transport spec are nailed down, and no browsers support it.

You can, however, use Flash where available to provide your script with a fallback until WebSocket is widely available. Gimite's web-socket-js is one free example of such. However you are subject to the same limitations as Flash Sockets then, namely that your server has to be able to spit out a cross-domain policy on request to the socket port, and you will often have difficulties with proxies/firewalls. (Flash sockets are made directly; for someone without direct public IP access who can only get out of the network through an HTTP proxy, they won't work.)

Unless you really need low-latency two-way communication, you are better off sticking with XMLHttpRequest for now.

Go to Android Manifest.xml and be sure to add the <uses-permission tag > inside the manifest tag but Outside of all other tags..

<manifest xlmns:android...>

 <uses-permission android:name="android.permission.INTERNET"></uses-permission>
</manifest>

This is an example of the permission of using Internet.

For others, if clearfix does not solve this for you, add margins to the non-floated sibling that is/are the same as the width(s) of the floated sibling(s).

With 'Enter' is better use ReadLine() or Read(2), because key 'Enter' generate 2 symbols. If user enter any text next Pause() also wil be skipped even with Read(2). So ReadLine() is better:

Sub Pause()
    WScript.Echo ("Press Enter to continue")
    z = WScript.StdIn.ReadLine()
End Sub

More examples look in http://technet.microsoft.com/en-us/library/ee156589.aspx

It also happens when the view returned by onCreateView() isn't the view that was inflated.

Example:

View rootView = inflater.inflate(R.layout.my_fragment, container, false);

TextView textView = (TextView) rootView.findViewById(R.id.text_view);
textView.setText("Some text.");

return textView;

Fix:

return rootView;

Instead of:

return textView; // or whatever you returned

Installing psqlODBC on 64bit Windows

Though you can install 32 bit ODBC drivers on Win X64 as usual, you can't configure 32-bit DSNs via ordinary control panel or ODBC datasource administrator.

How to configure 32 bit ODBC drivers on Win x64

Configure ODBC DSN from %SystemRoot%\syswow64\odbcad32.exe

1. Start > Run
2. Enter: %SystemRoot%\syswow64\odbcad32.exe
3. Hit return.
4. Open up ODBC and select under the System DSN tab.
5. Select PostgreSQL Unicode

You may have to play with it and try different scenarios, think outside-the-box, remember this is open source.

Try this:

CREATE TABLE SCHEMA.NEW_TB LIKE SCHEMA.OLD_TB;
INSERT INTO SCHEMA.NEW_TB (SELECT * FROM SCHEMA.OLD_TB);

Options that are not copied include:

• Check constraints
• Column default values
• Column comments
• Foreign keys
• Logged and compact option on BLOB columns
• Distinct types

Assuming that you want to get a value from the user input in html textbox whenever the user clicks 'Click' button, and then call a python function (mypythonfunction) that you wrote inside mypythoncode.py. Note that "btn" class is defined in a css file.

inside templateHTML.html:

<form action="#" method="get">
 <input type="text" value="8" name="mytextbox" size="1"/>
 <input type="submit" class="btn" value="Click" name="mybtn">
</form>

inside view.py:

import mypythoncode

def request_page(request):
  if(request.GET.get('mybtn')):
    mypythoncode.mypythonfunction( int(request.GET.get('mytextbox')) )
return render(request,'myApp/templateHTML.html')

This function:

• "Proper Cases" all "UPPER CASE" words that are delimited by white space
• leaves "lower case words" alone
• works properly even for non-English alphabets
• is portable in that it does not use fancy features of recent SQL server versions
• can be easily changed to use NCHAR and NVARCHAR for unicode support,as well as any parameter length you see fit
• white space definition can be configured

CREATE FUNCTION ToProperCase(@string VARCHAR(255)) RETURNS VARCHAR(255)
AS
BEGIN
  DECLARE @i INT           -- index
  DECLARE @l INT           -- input length
  DECLARE @c NCHAR(1)      -- current char
  DECLARE @f INT           -- first letter flag (1/0)
  DECLARE @o VARCHAR(255)  -- output string
  DECLARE @w VARCHAR(10)   -- characters considered as white space

  SET @w = '[' + CHAR(13) + CHAR(10) + CHAR(9) + CHAR(160) + ' ' + ']'
  SET @i = 1
  SET @l = LEN(@string)
  SET @f = 1
  SET @o = ''

  WHILE @i <= @l
  BEGIN
    SET @c = SUBSTRING(@string, @i, 1)
    IF @f = 1 
    BEGIN
     SET @o = @o + @c
     SET @f = 0
    END
    ELSE
    BEGIN
     SET @o = @o + LOWER(@c)
    END

    IF @c LIKE @w SET @f = 1

    SET @i = @i + 1
  END

  RETURN @o
END

Result:

dbo.ToProperCase('ALL UPPER CASE and    SOME lower ÄÄ ÖÖ ÜÜ ÉÉ ØØ CC ÆÆ')
-----------------------------------------------------------------
All Upper Case and      Some lower Ää Öö Üü Éé Øø Cc Ææ

To clone a repository and place it in a specified directory use "git clone [url] [directory]". For example

git clone https://github.com/ryanb/railscasts-episodes.git Rails

will create a directory named "Rails" and place it in the new directory. Click here for more information.

Work with checkboxes using observables

You could even choose to use a behaviourSubject to utilize the power of observables so you can start a certain chain of reaction starting at the isChecked$ observable.

In your component.ts:

public isChecked$ = new BehaviorSubject(false);
toggleChecked() {
  this.isChecked$.next(!this.isChecked$.value)
}

In your template

<input type="checkbox" [checked]="isChecked$ | async" (change)="toggleChecked()">

If all above stuffs not works. try this. If you are using IntelliJ. Check below setting:

May be ~/.m2/settings.xml is restricting to connect to internet.

If you are using jquery 1.7+, this works well:

$("donotscrollme").on("touchmove", false);

This was answered ages ago and probably not relevant, but just in case. When I was confronted with this issue, I simply used an if statement instead of switch, it solved the error. It is of course a workaround and probably not the "right" solution, but in my case it was just enough.

Edit: 2021.01.21

This Answer is a bit misleading, And I would like to clarify it.

1. Replacing a switch statement with an if should not be considered as a goto solution, there are very good reasons why both concepts of switch and if exist in software development, as well as performance matters to consider when choosing between the two.
2. Although I provide a solution to the presented error, My answer sheds no light on "why" the problem occurs but instead offers a way around the problem.

In my specific case, using an if statement instead was just enough to solve the problem. Developers should take the time and decide if this is the right solution for the current problem you have at hand.

Thus this answer should be considered solely as a workaround in specific cases as stated in my first response, and by no means as the correct answer to this question

Might help someone else : I encountered the same kind of issues while I had done some "copy-paste" from a side Microsoft Word document, where I took notes, to my shell script(s).

Re-writing, manually, the exact same code in the script just solved this.

It was quite un-understandable at first, I think Word's hidden characters and/or formatting were the issue. Obvious but not see-able ... I lost about one hour on this (I'm no shell expert, as you might guess ...)

You might use Osync: http://www.netpower.fr/osync , which is rsync based with intelligent deletion propagation. it has also multiple options like resuming a halted execution, soft deletion, and time control.

Try this out. The basic strategy is to sort the particular column independently and remember the original row of the entry. The rest of the code will cycle through the sorted column data and swap out the rows in the array. The tricky part is remembing to update the original column as the swap portion will effectively alter the original column.

Look at the following example code:

public class MyWorker
{
    public SharedData state;
    public void DoWork(SharedData someData)
    {
        this.state = someData;
        while (true) ;
    }

}

public class SharedData {
    X myX;
    public getX() { etc
    public setX(anX) { etc

}

public class Program
{
    public static void Main()
    {
        SharedData data = new SharedDate()
        MyWorker work1 = new MyWorker(data);
        MyWorker work2 = new MyWorker(data);
        Thread thread = new Thread(new ThreadStart(work1.DoWork));
        thread.Start();
        Thread thread2 = new Thread(new ThreadStart(work2.DoWork));
        thread2.Start();
    }
}

In this case, the thread class MyWorker has a variable state. We initialise it with the same object. Now you can see that the two workers access the same SharedData object. Changes made by one worker are visible to the other.

You have quite a few remaining issues. How does worker 2 know when changes have been made by worker 1 and vice-versa? How do you prevent conflicting changes? Maybe read: this tutorial.

Yes, if you really want / need to do it you can use PowerMock. This should be considered a last resort. With PowerMock you can cause it to return a mock from the call to the constructor. Then do the verify on the mock. That said, csturtz's is the "right" answer.

Here is the link to Mock construction of new objects

private void btnSent_Click(object sender, EventArgs e)
{
    try
    {
        MailMessage mail = new MailMessage();
        SmtpClient SmtpServer = new SmtpClient("smtp.gmail.com");

        mail.From = new MailAddress(txtAcc.Text);
        mail.To.Add(txtToAdd.Text);
        mail.Subject = txtSub.Text;
        mail.Body = txtContent.Text;
        System.Net.Mail.Attachment attachment;
        attachment = new System.Net.Mail.Attachment(txtAttachment.Text);
        mail.Attachments.Add(attachment);

        SmtpServer.Port = 587;
        SmtpServer.Credentials = new System.Net.NetworkCredential(txtAcc.Text, txtPassword.Text);

        SmtpServer.EnableSsl = true;

        SmtpServer.Send(mail);
        MessageBox.Show("mail send");
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

private void button1_Click(object sender, EventArgs e)
{
    MailMessage mail = new MailMessage();
    openFileDialog1.ShowDialog();
    System.Net.Mail.Attachment attachment;
    attachment = new System.Net.Mail.Attachment(openFileDialog1.FileName);
    mail.Attachments.Add(attachment);
    txtAttachment.Text =Convert.ToString (openFileDialog1.FileName);
}

This flexbox principle also works horizontally

During calculations of flex bases and flexible lengths, auto margins are treated as 0.
Prior to alignment via justify-content and align-self, any positive free space is distributed to auto margins in that dimension.

Setting an automatic left margin for the Last Item will do the work.

.last-item {
  margin-left: auto;
}

Code Example:

.container {_x000D_
  display: flex;_x000D_
  width: 400px;_x000D_
  outline: 1px solid black;_x000D_
}_x000D_
_x000D_
p {_x000D_
  height: 50px;_x000D_
  width: 50px;_x000D_
  margin: 5px;_x000D_
  background-color: blue;_x000D_
}_x000D_
_x000D_
.last-item {_x000D_
  margin-left: auto;_x000D_
}

<div class="container">_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p></p>_x000D_
  <p class="last-item"></p>_x000D_
</div>

Codepen Snippet

This can be very useful for Desktop Footers.

As Envato did here with the company logo.

Codepen Snippet

tr td 
{
    border-bottom: 2px solid silver;
}

or if you want the border inside the TR tag, you can do this:

tr td {
    box-shadow: inset 0px -2px 0px silver;
}

Element.scrollHeight is a property, not a function, as noted here. As noted here, the scrollHeight property is only supported after IE8. If you need it to work before that, temporarily set the CSS overflow and height to auto, which will cause the div to take the maximum height it needs. Then get the height, and change the properties back to what they were before.

Don't match an email with a regex. It's extremely ugly and long and complicated and your regex parser probably can't handle it anyway. Try to find a library routine for matching them. If you only want to solve the practical problem of matching an email address (that is, if you want wrong code that happens to (usually) work), use the regular-expressions.info link someone else submitted.

As for the empty string, ^$ is mentioned by multiple people and will work fine.

For those having this problem on IIS servers.

Explanation: sometimes certificates carry an URL of an intermediate certificate instead of the actual certificate. Desktop browsers can DOWNLOAD the missing intermediate certificate using this URL. But older mobile browsers are unable to do that. So they throw this warning.

You need to

1) make sure all intermediate certificates are served by the server

2) disable unneeded certification paths in IIS - Under "Trusted Root Certification Authorities", you need to "disable all purposes" for the certificate that triggers the download.

PS. my colleague has wrote a blog post with more detailed steps: https://www.jitbit.com/maxblog/21-errcertauthorityinvalid-on-android-and-iis/

Well, why this exists in general is probably different than why it exists in your example.

It all started half a century ago with repurposing hardcopy communication terminals as computer user interfaces. In the initial Unix and C era that was the ASR-33 Teletype.

This device was slow (10 cps) and noisy and ugly and its view of the ASCII character set ended at 0x5f, so it had (look closely at the pic) none of the keys:

{ | } ~ 

The trigraphs were defined to fix a specific problem. The idea was that C programs could use the ASCII subset found on the ASR-33 and in other environments missing the high ASCII values.

Your example is actually two of ??!, each meaning |, so the result is ||.

However, people writing C code almost by definition had modern equipment,¹ so my guess is: someone showing off or amusing themself, leaving a kind of Easter egg in the code for you to find.

It sure worked, it led to a wildly popular SO question.

                                            ^{ASR-33 Teletype}

Check out the article Visual Studio .NET Platform Target Explained.

The default setting, "Any CPU", means that the assembly will run natively on the CPU it is currently running on. Meaning, it will run as 64-bit on a 64-bit machine and 32-bit on a 32-bit machine. If the assembly is called from a 64-bit application, it will perform as a 64-bit assembly and so on.

The above link has been reported to be broken, so here is another article with a similar explanation: What AnyCPU Really Means As Of .NET 4.5 and Visual Studio 11

Here's a variant that lets you use a regex pattern for initial filtering, change the regex to be get the filtering you desire.

files=($(find -E . -type f -regex "^.*$"))
for item in ${files[*]}
do
  printf "   %s\n" $item
done

That's not how you send file on postman. What you did is sending a string which is the path of your image, nothing more.

What you should do is;

1. After setting request method to POST, click to the 'body' tab.
2. Select form-data. At first line, you'll see text boxes named key and value. Write 'image' to the key. You'll see value type which is set to 'text' as default. Make it File and upload your file.
3. Then select 'raw' and paste your json file. Also just next to the binary choice, You'll see 'Text' is clicked. Make it JSON.

You're ready to go.

In your Django view,

from rest_framework.views import APIView
from rest_framework.parsers import MultiPartParser
from rest_framework.decorators import parser_classes

@parser_classes((MultiPartParser, ))
class UploadFileAndJson(APIView):

    def post(self, request, format=None):
        thumbnail = request.FILES["file"]
        info = json.loads(request.data['info'])
        ...
        return HttpResponse()

Working Solution that listens to if the user has started to navigate down the list with the keyboard rather than triggering the false navigation each time

Here are the important bits

// search input
const searchInput = document.getElementById('js-search-input');

// Google Maps autocomplete
const autocomplete = new google.maps.places.Autocomplete(searchInput);

// Has user pressed the down key to navigate autocomplete options?
let hasDownBeenPressed = false;

// Listener outside to stop nested loop returning odd results
searchInput.addEventListener('keydown', (e) => {
    if (e.keyCode === 40) {
        hasDownBeenPressed = true;
    }
});

// GoogleMaps API custom eventlistener method
google.maps.event.addDomListener(searchInput, 'keydown', (e) => {

    // Maps API e.stopPropagation();
    e.cancelBubble = true;

    // If enter key, or tab key
    if (e.keyCode === 13 || e.keyCode === 9) {
        // If user isn't navigating using arrows and this hasn't ran yet
        if (!hasDownBeenPressed && !e.hasRanOnce) {
            google.maps.event.trigger(e.target, 'keydown', {
                keyCode: 40,
                hasRanOnce: true,
            });
        }
    }
});

 // Clear the input on focus, reset hasDownBeenPressed
searchInput.addEventListener('focus', () => {
    hasDownBeenPressed = false;
    searchInput.value = '';
});

// place_changed GoogleMaps listener when we do submit
google.maps.event.addListener(autocomplete, 'place_changed', function() {

    // Get the place info from the autocomplete Api
    const place = autocomplete.getPlace();

    //If we can find the place lets go to it
    if (typeof place.address_components !== 'undefined') {          
        // reset hasDownBeenPressed in case they don't unfocus
        hasDownBeenPressed = false;
    }

});

Update by Arkadiy: I've observed more correct behavior of System.currentTimeMillis() on Windows 7 in Oracle Java 8. The time was returned with 1 millisecond precision. The source code in OpenJDK has not changed, so I do not know what causes the better behavior.

David Holmes of Sun posted a blog article a couple years ago that has a very detailed look at the Java timing APIs (in particular System.currentTimeMillis() and System.nanoTime()), when you would want to use which, and how they work internally.

Inside the Hotspot VM: Clocks, Timers and Scheduling Events - Part I - Windows

One very interesting aspect of the timer used by Java on Windows for APIs that have a timed wait parameter is that the resolution of the timer can change depending on what other API calls may have been made - system wide (not just in the particular process). He shows an example where using Thread.sleep() will cause this resolution change.

i also got same error , i just change the java version in pom.xml from 11 to 1.8 and it's work fine.

Try giving some padding bottom to your constraint layout like below

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/top"
        android:fillViewport="true">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingBottom="100dp">
        </android.support.constraint.ConstraintLayout>

    </ScrollView>

In JavaScript the sort() method's default behaviour is to sort values in an array alphabetically.

To sort by number you have to define a numeric sort function (which is very easy):

...
function sortNumber(a, b)
{
  return a - b;
}

numArray = numArray.sort(sortNumber);

A comma at the end of the print statement omits the new line.

for i in xrange(1,100):
  print i,

but this does not overwrite.

try using .animate instead of .css or even just on the opacity one and leave .css on the display?? may b

jQuery(document).ready(function(){
if (jQuery('#nav .drop').animate('display') === 'block') {
    jQuery('#main').animate('opacity') = '0.6';

Override toString() method in Student class as below:

   @Override
   public String toString() {
        return ("StudentName:"+this.getStudentName()+
                    " Student No: "+ this.getStudentNo() +
                    " Email: "+ this.getEmail() +
                    " Year : " + this.getYear());
   }

EDIT:

See @Simba Answer for valid solution

submodule.<name>.update is what you want to change, see the docs - default checkout
submodule.<name>.branch specify remote branch to be tracked - default master

OLD ANSWER:

Personally I hate answers here which direct to external links which may stop working over time and check my answer here (Unless question is duplicate) - directing to question which does cover subject between the lines of other subject, but overall equals: "I'm not answering, read the documentation."

So back to the question: Why does it happen?

Situation you described

After pulling changes from server, many times my submodule head gets detached from master branch.

This is a common case when one does not use submodules too often or has just started with submodules. I believe that I am correct in stating, that we all have been there at some point where our submodule's HEAD gets detached.

• Cause: Your submodule is not tracking correct branch (default master).
  Solution: Make sure your submodule is tracking the correct branch

$ cd <submodule-path>
# if the master branch already exists locally:
# (From git docs - branch)
# -u <upstream>
# --set-upstream-to=<upstream>
#    Set up <branchname>'s tracking information so <upstream>
#    is considered <branchname>'s upstream branch.
#    If no <branchname> is specified, then it defaults to the current branch.
$ git branch -u <origin>/<branch> <branch>
# else:
$ git checkout -b <branch> --track <origin>/<branch>

• Cause: Your parent repo is not configured to track submodules branch.
  Solution: Make your submodule track its remote branch by adding new submodules with the following two commands.
  • First you tell git to track your remote <branch>.
  • you tell git to perform rebase or merge instead of checkout
  • you tell git to update your submodule from remote.

    $ git submodule add -b <branch> <repository> [<submodule-path>]
    $ git config -f .gitmodules submodule.<submodule-path>.update rebase
    $ git submodule update --remote

• If you haven't added your existing submodule like this you can easily fix that:
  • First you want to make sure that your submodule has the branch checked out which you want to be tracked.

    $ cd <submodule-path>
    $ git checkout <branch>
    $ cd <parent-repo-path>
    # <submodule-path> is here path releative to parent repo root
    # without starting path separator
    $ git config -f .gitmodules submodule.<submodule-path>.branch <branch>
    $ git config -f .gitmodules submodule.<submodule-path>.update <rebase|merge>

In the common cases, you already have fixed by now your DETACHED HEAD since it was related to one of the configuration issues above.

fixing DETACHED HEAD when .update = checkout

$ cd <submodule-path> # and make modification to your submodule
$ git add .
$ git commit -m"Your modification" # Let's say you forgot to push it to remote.
$ cd <parent-repo-path>
$ git status # you will get
Your branch is up-to-date with '<origin>/<branch>'.
Changes not staged for commit:
    modified:   path/to/submodule (new commits)
# As normally you would commit new commit hash to your parent repo
$ git add -A
$ git commit -m"Updated submodule"
$ git push <origin> <branch>.
$ git status
Your branch is up-to-date with '<origin>/<branch>'.
nothing to commit, working directory clean
# If you now update your submodule
$ git submodule update --remote
Submodule path 'path/to/submodule': checked out 'commit-hash'
$ git status # will show again that (submodule has new commits)
$ cd <submodule-path>
$ git status
HEAD detached at <hash>
# as you see you are DETACHED and you are lucky if you found out now
# since at this point you just asked git to update your submodule
# from remote master which is 1 commit behind your local branch
# since you did not push you submodule chage commit to remote. 
# Here you can fix it simply by. (in submodules path)
$ git checkout <branch>
$ git push <origin>/<branch>
# which will fix the states for both submodule and parent since 
# you told already parent repo which is the submodules commit hash 
# to track so you don't see it anymore as untracked.

But if you managed to make some changes locally already for submodule and commited, pushed these to remote then when you executed 'git checkout ', Git notifies you:

$ git checkout <branch>
Warning: you are leaving 1 commit behind, not connected to any of your branches:
If you want to keep it by creating a new branch, this may be a good time to do so with:

The recommended option to create a temporary branch can be good, and then you can just merge these branches etc. However I personally would use just git cherry-pick <hash> in this case.

$ git cherry-pick <hash> # hash which git showed you related to DETACHED HEAD
# if you get 'error: could not apply...' run mergetool and fix conflicts
$ git mergetool
$ git status # since your modifications are staged just remove untracked junk files
$ rm -rf <untracked junk file(s)>
$ git commit # without arguments
# which should open for you commit message from DETACHED HEAD
# just save it or modify the message.
$ git push <origin> <branch>
$ cd <parent-repo-path>
$ git add -A # or just the unstaged submodule
$ git commit -m"Updated <submodule>"
$ git push <origin> <branch>

Although there are some more cases you can get your submodules into DETACHED HEAD state, I hope that you understand now a bit more how to debug your particular case.

here you need to skip int 0 like following:

val = s.nextInt();
  if ((val < min) && (val!=0)) {
      min = val;
  }

Building on this question, I use the following code to indent my messages:

String prefix1 = "short text:";
String prefix2 = "looooooooooooooong text:";
String msg = "indented";
/*
* The second string begins after 40 characters. The dash means that the
* first string is left-justified.
*/
String format = "%-40s%s%n";
System.out.printf(format, prefix1, msg);
System.out.printf(format, prefix2, msg);

This is the output:

short text:                             indented
looooooooooooooong text:                indented

This is documented in section "Flag characters" in man 3 printf.

Two ways to do that..

Option 1:

1.  Go to "Start" -> "Run".

2.  Write "CMD" and press on "Enter" key.

3.  Write the command "net statistics server" and press on "Enter" key.

4.  The line that start with "Statistics since …" provides the time that the server was up from.


  The command "net stats srv" can be use instead.

Option 2:

I had this problem on Windows 8, but I solved the problem by updating all of Android Studio's plugins with the SDK Manager, then restarting the computer.

sorry for the sudo code..I'm on a phone. ;)

between = (time < string2 && time > string1);
if (string1 > string2)  between = !between;

if they are timestamps or strings this works. just change the variable names to match

I'm not sure try below steps,i think may be error occurs below reasons.

• you rename some files outside XCode. To solve it remove the files from your project and re-import the files in your project.
• check and add missing Nib file in Build phases->Copy bundle resources.finally check the nib name spelling, it's correct, case sensitive.
• check the properties of the .xib/storyboard files in the file inspector ,the property "Target Membership" pitch on the select box,then your xib/storyboard file was linked with your target.
• such as incorrect type of NIB.Right click on the file and click "Get Info" to verify that the type is what you would expect.

So maybe you want to have this in your index.html to load the library, script, and initialize the app with a view:

<html>
  <body ng-app="yourApp">
    <div class="span12">
      <div ng-view=""></div>
    </div>
    <script src="http://code.angularjs.org/1.2.0-rc.2/angular.js"></script>
    <script src="script.js"></script>
  </body>
</html>

Then yourView.html could just be:

<div>
  <h1>{{ stuff.h1 }}</h1>
  <p>{{ stuff.content }}</p>
</div>

scripts.js could have your controller with data $scope'd to it.

angular.module('yourApp')
    .controller('YourCtrl', function ($scope) {
      $scope.stuff = {
        'h1':'Title',
        'content':"A paragraph..."
      };
    });

Lastly, you'll have to config routes and assign the controller to view for it's $scope (i.e. your data object)

angular.module('yourApp', [])
.config(function ($routeProvider) {
  $routeProvider
    .when('/', {
      templateUrl: 'views/yourView.html',
      controller: 'YourCtrl'
    });
});

I haven't tested this, sorry if there's a bug but I think this is the Angularish way to get data

Jun 10 2015: Note from the author of gulp-uglifyjs:

DEPRECATED: This plugin has been blacklisted as it relies on Uglify to concat the files instead of using gulp-concat, which breaks the "It should do one thing" paradigm. When I created this plugin, there was no way to get source maps to work with gulp, however now there is a gulp-sourcemaps plugin that achieves the same goal. gulp-uglifyjs still works great and gives very granular control over the Uglify execution, I'm just giving you a heads up that other options now exist.

Feb 18 2015: gulp-uglify and gulp-concat both work nicely with gulp-sourcemaps now. Just make sure to set the newLine option correctly for gulp-concat; I recommend \n;.

Original Answer (Dec 2014): Use gulp-uglifyjs instead. gulp-concat isn't necessarily safe; it needs to handle trailing semi-colons correctly. gulp-uglify also doesn't support source maps. Here's a snippet from a project I'm working on:

gulp.task('scripts', function () {
    gulp.src(scripts)
        .pipe(plumber())
        .pipe(uglify('all_the_things.js',{
            output: {
                beautify: false
            },
            outSourceMap: true,
            basePath: 'www',
            sourceRoot: '/'
        }))
        .pipe(plumber.stop())
        .pipe(gulp.dest('www/js'))
});

Using exclude and filter

results = Model.objects.filter(x=5).exclude(a=true)

I had some more thoughts on this:

1) Remember that maps represent a physical organization. Store the latitude/longitude of every intersection. You don't need to check much beyond the points that lie in the direction of your target. Only if you find yourself blocked do you need to go beyond this. If you store an overlay of superior connections you can limit it even more--you will normally never go across one of those in a way that goes away from your final destination.

2) Divide up the world into a whole bunch of zones defined by limited connectivity, define all connectivity points between the zones. Find what zones your source and target are in, for the start and end zone route from your location to each connection point, for the zones between simply map between connection points. (I suspect a lot of the latter is already pre-calculated.)

Note that zones can be smaller than a metropolitan area. Any city with terrain features that divide it up (say, a river) would be multiple zones.

Just use the JSON.stringify method and pass it through as the "data" parameter for the $.ajax function, like follows:

$.ajax({
    type: "POST",
    url: "index.php",
    dataType: "json",
    data: JSON.stringify({ paramName: info }),
    success: function(msg){
        $('.answer').html(msg);
    }
});

You just need to make sure you include the JSON2.js file in your page...

I solved this issue by removing all the NuGet packages from solution and reinstalling them. One of the NuGet Packages was dependent upon NewtonSoft and it was not showing in references

You cannot directly use a SQL statement in a PL/SQL expression:

ERROR at line 2:
ORA-06550: line 2, column 6:
PLS-00103: Encountered the symbol "SELECT" when expecting one of the following:

SQL> declare
  2     v_count number;
  3  begin
  4     select count(*) into v_count from dual;

  8     end if;
  9  end;

PL/SQL procedure successfully completed.

Of course, you may be able to do the whole thing in SQL:

update my_table
set x = y
where (select count(*) from other_table) >= 1;

It's difficult to prove that something is not possible. Other than the simple test case above, you can look at the syntax diagram for the IF statement; you won't see a SELECT statement in any of the branches.

If you compile multiple files in the same line, ensure that you use javac only once and not for every class file.

This works for me:

#! /bin/bash

CACERTS=$(readlink -e $(dirname $(readlink -e $(which keytool)))/../lib/security/cacerts)

if keytool -list -keystore $CACERTS -storepass changeit > /dev/null ; then

C++ doesn't allow non-constant values for the size of an array. That's just the way it was designed.

C99 allows the size of an array to be a variable, but I'm not sure it is allowed for two dimensions. Some C++ compilers (gcc) will allow this as an extension, but you may need to turn on a compiler option to allow it.

And I almost missed it - you need to declare a variable name, not just the array dimensions.

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

A closely related question: How to add reference to System.Web.Optimization for MVC-3-converted-to-4 app

Personally I think that "" + i does look as the original question poster states "smelly". I have used a lot of OO languages besides Java. If that syntax was intended to be appropriate then Java would just interpret the i alone without needing the "" as desired to be converted to a string and do it since the destination type is unambiguous and only a single value would be being supplied on the right. The other seems like a 'trick" to fool the compiler, bad mojo when different versions of Javac made by other manufacturers or from other platforms are considered if the code ever needs to be ported. Heck for my money it should like many other OOL's just take a Typecast: (String) i. winks

Given my way of learning and for ease of understanding such a construct when reading others code quickly I vote for the Integer.toString(i) method. Forgetting a ns or two in how Java implements things in the background vs. String.valueOf(i) this method feels right to me and says exactly what is happening: I have and Integer and I wish it converted to a String.

A good point made a couple times is perhaps just using StringBuilder up front is a good answer to building Strings mixed of text and ints or other objects since thats what will be used in the background anyways right?

Just my two cents thrown into the already well paid kitty of the answers to the Mans question... smiles

EDIT TO MY OWN ANSWER AFTER SOME REFLECTION:

Ok, Ok, I was thinking on this some more and String.valueOf(i) is also perfectly good as well it says: I want a String that represents the value of an Integer. lol, English is by far more difficult to parse then Java! But, I leave the rest of my answer/comment... I was always taught to use the lowest level of a method/function chain if possible and still maintains readablity so if String.valueOf calls Integer.toString then Why use a whole orange if your just gonna peel it anyways, Hmmm?

To clarify my comment about StringBuilder, I build a lot of strings with combos of mostly literal text and int's and they wind up being long and ugly with calls to the above mentioned routines imbedded between the +'s, so seems to me if those become SB objects anyways and the append method has overloads it might be cleaner to just go ahead and use it... So I guess I am up to 5 cents on this one now, eh? lol...

Somewhere in your initialisation put this code.

Array.prototype.contains = function contains(obj) {
    for (var i = 0; i < this.length; i++) {
        if (this[i] === obj) {
            return true;
        }
    }
    return false;
};

Then, you can use it this way:

<li ng-class="{approved: selectedForApproval.contains(jobSet)}"></li>

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy() (or .values for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.

For example, you can use ndarray.max() along the first axis.

# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
   A  B
0  1 -2
1  2  8
2  3  1

df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns, 
# df['C'] = df.values.max(1) 
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

If your data has NaNs, you will need numpy.nanmax:

df['C'] = np.nanmax(df.values, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

You can also use numpy.maximum.reduce. numpy.maximum is a ufunc (Universal Function), and every ufunc has a reduce:

df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

np.maximum.reduce and np.max appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).

The graph was generated using perfplot. Benchmarking code, for reference:

import pandas as pd
import perfplot

np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))

perfplot.show(
    setup=lambda n: pd.concat([df_] * n, ignore_index=True),
    kernels=[
        lambda df: df.assign(new=df.max(axis=1)),
        lambda df: df.assign(new=df.values.max(1)),
        lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
        lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
    ],
    labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],
    n_range=[2**k for k in range(0, 15)],
    xlabel='N (* len(df))',
    logx=True,
    logy=True)

The quickest way, just to get this working is to use the web pack from another location, this will stop you having to install it globally or if npm run webpack fails.

When you install webpack with npm it goes inside the "node_modules\.bin" folder of your project.

in command prompt (as administrator)

1. go to the location of the project where your webpack.config.js is located.
2. in command prompt write the following

"C:\Users\..\ProjectName\node_modules\.bin\webpack" --config webpack.config.vendor.js

From Java 8 you can use this simple method for picking a random date from the date picker

List<WebElement> datePickerDays = driver.findElements(By.tagName("td"));
datePickerDays.stream().filter(e->e.getText().equals(whichDateYouWantToClick)).findFirst().get().click();

Having a similar case and I couldn't use StackAttacks solution as he's referring to SDL2 which is for the legacy code I'm using too new.

Fortunately our friends from askUbuntu had something similar:

Download SDL

tar xvf SDL-1.2.tar.gz
cd SDL-1.2
./configure
make
sudo make install

Arriving a little late to this discussion but this is my contribution fwiw. I have an IList<Guid> OrderIds to be converted to a CSV string but following is generic and works unmodified with other types:

string csv = OrderIds.Aggregate(new StringBuilder(),
             (sb, v) => sb.Append(v).Append(","),
             sb => {if (0 < sb.Length) sb.Length--; return sb.ToString();});

Short and sweet, uses StringBuilder for constructing new string, shrinks StringBuilder length by one to remove last comma and returns CSV string.

I've updated this to use multiple Append()'s to add string + comma. From James' feedback I used Reflector to have a look at StringBuilder.AppendFormat(). Turns out AppendFormat() uses a StringBuilder to construct the format string which makes it less efficient in this context than just using multiple Appends()'s.

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

<div class="Owner Joe" />

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

Or even with the new HTML5 custom data attributes:

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

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

I installed ArcGIS Pro 1.4 and it didn't register the Python 3.5.2 it installed which prevented me from installing any add-ons. I resolved this by using the "reg" command in an Administrator PowerShell session to manually create and populate the necessary registry keys/values (where Python is installed in C:\Python35):

reg add "HKLM\Software\Python\PythonCore\3.5\Help\Main Python Documentation" /reg:64 /ve /t REG_SZ /d "C:\Python35\Doc\Python352.chm"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\"
reg add "HKLM\Software\Python\PythonCore\3.5\InstallPath\InstallGroup" /reg:64 /ve /t REG_SZ /d "Python 3.5"
reg add "HKLM\Software\Python\PythonCore\3.5\PythonPath" /reg:64 /ve /t REG_SZ /d "C:\Python35\Lib;C:\Python35\DLLs;C:\Python35\Lib\lib-tk"

I find this easier than using Registry Editor but that's solely a personal preference.

The same commands can be executed in CMD.EXE session if you prefer; just make sure you run it as Administrator.

This is what you're looking for.

I had this problem too. And like you, the answer is very hard to find. But there IS an easy way to get the ViewHolder from a specific position (something you'll probably do a lot in the Adapter).

myRecyclerView.findViewHolderForAdapterPosition(pos);

NOTE: If the View has been recycled, this will return null. Thanks to Michael for quickly catching my important omission.

Always try to do an associative fetch, that way you can easy get what you want in multiple case result

Here's an example

$result = $mysqli->query("SELECT COUNT(*) AS cityCount FROM myCity")
$row = $result->fetch_assoc();
echo $row['cityCount']." rows in table myCity.";

I faced the same error, in my case I miss-spelled ng-model directive something like "ng-moel"

Wrong one: ng-moel="user.name" Right one: ng-model="user.name"

always Until you fully understand the differences and implications of using the == and === operators, use the === operator since it will save you from obscure (non-obvious) bugs and WTFs. The "regular" == operator can have very unexpected results due to the type-coercion internally, so using === is always the recommended approach.

For insight into this, and other "good vs. bad" parts of Javascript read up on Mr. Douglas Crockford and his work. There's a great Google Tech Talk where he summarizes lots of good info: http://www.youtube.com/watch?v=hQVTIJBZook

Update:

The You Don't Know JS series by Kyle Simpson is excellent (and free to read online). The series goes into the commonly misunderstood areas of the language and explains the "bad parts" that Crockford suggests you avoid. By understanding them you can make proper use of them and avoid the pitfalls.

The "Up & Going" book includes a section on Equality, with this specific summary of when to use the loose (==) vs strict (===) operators:

To boil down a whole lot of details to a few simple takeaways, and help you know whether to use == or === in various situations, here are my simple rules:

• If either value (aka side) in a comparison could be the true or false value, avoid == and use ===.
• If either value in a comparison could be of these specific values (0, "", or [] -- empty array), avoid == and use ===.
• In all other cases, you're safe to use ==. Not only is it safe, but in many cases it simplifies your code in a way that improves readability.

I still recommend Crockford's talk for developers who don't want to invest the time to really understand Javascript—it's good advice for a developer who only occasionally works in Javascript.

The valid syntax with named fields:

  var array = [];

     @foreach (var item in model.List)
     {
        @:array.push({ 
                       "Project": "@item.Project",
                       "ProjectOrgUnit": "@item.ProjectOrgUnit"
                     });
     }

According to the Python documentation:

The sequence

prog = re.compile(pattern)
result = prog.match(string)

is equivalent to

result = re.match(pattern, string)

but using re.compile() and saving the resulting regular expression object for reuse is more efficient when the expression will be used several times in a single program.

So my conclusion is, if you are going to match the same pattern for many different texts, you better precompile it.

What I did to resolve the same problem was:

Open pg_hba.conf file with gedit editor from the terminal:

sudo gedit /etc/postgresql/9.5/main/pg_hba.conf

It will ask for password. Enter your admin login password. This will open gedit with the file. Paste the following line:

host  all   all  127.0.0.1/32  trust

just below -

# Database administrative login by Unix domain socket

Save and close it. Close the terminal and open it again and run this command:

psql -U postgres

You will now enter the psql console. Now change the password by entering this:

ALTER USER [your prefered user name] with password '[desired password]';

If it says user does not exist then instead of ALTER use CREATE.

Lastly, remove that certain line you pasted in pg_hba and save it.

Hard links are useful when the original file is getting moved around. For example, moving a file from /bin to /usr/bin or to /usr/local/bin. Any symlink to the file in /bin would be broken by this, but a hardlink, being a link directly to the inode for the file, wouldn't care.

Hard links may take less disk space as they only take up a directory entry, whereas a symlink needs its own inode to store the name it points to.

Hard links also take less time to resolve - symlinks can point to other symlinks that are in symlinked directories. And some of these could be on NFS or other high-latency file systems, and so could result in network traffic to resolve. Hard links, being always on the same file system, are always resolved in a single look-up, and never involve network latency (if it's a hardlink on an NFS filesystem, the NFS server would do the resolution, and it would be invisible to the client system). Sometimes this is important. Not for me, but I can imagine high-performance systems where this might be important.

I also think things like mmap(2) and even open(2) use the same functionality as hardlinks to keep a file's inode active so that even if the file gets unlink(2)ed, the inode remains to allow the process continued access, and only once the process closes it does the file really go away. This allows for much safer temporary files (if you can get the open and unlink to happen atomically, which there may be a POSIX API for that I'm not remembering, then you really have a safe temporary file) where you can read/write your data without anyone being able to access it. Well, that was true before /proc gave everyone the ability to look at your file descriptors, but that's another story.

Speaking of which, recovering a file that is open in process A, but unlinked on the file system revolves around using hardlinks to recreate the inode links so the file doesn't go away when the process which has it open closes it or goes away.

@Mike M. and I found an issue with the accepted answer (see our comments):

Basically, there is no point in going through the for loop if we are not concatenating the multipart message each time:

for (int i = 0; i < msgs.length; i++) {
    msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
    msg_from = msgs[i].getOriginatingAddress();
    String msgBody = msgs[i].getMessageBody();
}

Notice that we just set msgBody to the string value of the respective part of the message no matter what index we are on, which makes the entire point of looping through the different parts of the SMS message useless, since it will just be set to the very last index value. Instead we should use +=, or as Mike noted, StringBuilder:

All in all, here is what my SMS receiving code looks like:

if (myBundle != null) {
    Object[] pdus = (Object[]) myBundle.get("pdus"); // pdus is key for SMS in bundle

    //Object [] pdus now contains array of bytes
    messages = new SmsMessage[pdus.length];
    for (int i = 0; i < messages.length; i++) {
         messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); //Returns one message, in array because multipart message due to sms max char
         Message += messages[i].getMessageBody(); // Using +=, because need to add multipart from before also
    }

    contactNumber = messages[0].getOriginatingAddress(); //This could also be inside the loop, but there is no need
}

Just putting this answer out there in case anyone else has the same confusion.

A CSS selector approach could definitely work here. Try:

driver.findElement(By.CssSelector("a.item")).Click();

This will not work if there are other anchors before this one of the class item. You can better specify the exact element if you do something like "#my_table > a.item" where my_table is the id of a table that the anchor is a child of.

You should use both title and alt attributes to make it work in all browsers.

<button title="Hello World!" alt="Hello World!">Sample Button</button>

Aleksander Blomskøld's solution did not work for me for parameterized tests @RunWith(Parameterized.class) when using Maven. The tests were named correctly and also where found but not executed:

-------------------------------------------------------

-------------------------------------------------------
Running some.properly.named.test.run.with.maven.SomeTest
Tests run: 0, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.123 sec

A similar issue has been reported here.

In my case @Parameters is creating instances of each class in a package. The tests worked well when run locally in the IDE. However, when running Maven no classes where found with Aleksander Blomskøld's solution.

I did make it work with the following snipped which was inspired by David Pärsson's comment on Aleksander Blomskøld's answer:

Reflections reflections = new Reflections(new ConfigurationBuilder()
            .setScanners(new SubTypesScanner(false /* don't exclude Object.class */), new ResourcesScanner())
            .addUrls(ClasspathHelper.forJavaClassPath()) 
            .filterInputsBy(new FilterBuilder()
            .include(FilterBuilder.prefix(basePackage))));

Set<Class<?>> subTypesOf = reflections.getSubTypesOf(Object.class);

As of .NET 5, the implementation has changed. HttpClient still throws a TaskCanceledException, but now wraps a TimeoutException as InnerException. So you can easily check whether a request was canceled or timed out (code sample copied from linked blog post):

try
{
    using var response = await _client.GetAsync("http://localhost:5001/sleepFor?seconds=100");
}
// Filter by InnerException.
catch (TaskCanceledException ex) when (ex.InnerException is TimeoutException)
{
    // Handle timeout.
    Console.WriteLine("Timed out: "+ ex.Message);
}
catch (TaskCanceledException ex)
{
    // Handle cancellation.
    Console.WriteLine("Canceled: " + ex.Message);   
}

Target: customizing all back button on UINavigationBar to an white icon

Steps: 1. in "didFinishLaunchingWithOptions" method of AppDelete:

UIImage *backBtnIcon = [UIImage imageNamed:@"navBackBtn"];


if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
    [UINavigationBar appearance].tintColor = [UIColor whiteColor];
    [UINavigationBar appearance].backIndicatorImage = backBtnIcon;
    [UINavigationBar appearance].backIndicatorTransitionMaskImage = backBtnIcon;
}else{

    UIImage *backButtonImage = [backBtnIcon resizableImageWithCapInsets:UIEdgeInsetsMake(0, backBtnIcon.size.width - 1, 0, 0)];
    [[UIBarButtonItem appearance] setBackButtonBackgroundImage:backButtonImage  forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

    [[UIBarButtonItem appearance] setBackButtonTitlePositionAdjustment:UIOffsetMake(0, -backButtonImage.size.height*2) forBarMetrics:UIBarMetricsDefault];
}

2.in the viewDidLoad method of the common super ViewController class:

 if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) {
        UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithTitle:@""

        [self.navigationItem setBackBarButtonItem:backItem];
    }else{
        //do nothing
    }

It's been quite sometime since I asked this question. Now I understand it more clearly, I'm going to put a more complete answer to help others.

In Web API, it's very simple to remember how parameter binding is happening.

• if you POST simple types, Web API tries to bind it from the URL

• if you POST complex type, Web API tries to bind it from the body of the request (this uses a media-type formatter).

• If you want to bind a complex type from the URL, you'll use [FromUri] in your action parameter. The limitation of this is down to how long your data going to be and if it exceeds the url character limit.

  public IHttpActionResult Put([FromUri] ViewModel data) { ... }

• If you want to bind a simple type from the request body, you'll use [FromBody] in your action parameter.

  public IHttpActionResult Put([FromBody] string name) { ... }

as a side note, say you are making a PUT request (just a string) to update something. If you decide not to append it to the URL and pass as a complex type with just one property in the model, then the data parameter in jQuery ajax will look something like below. The object you pass to data parameter has only one property with empty property name.

var myName = 'ABC';
$.ajax({url:.., data: {'': myName}});

and your web api action will look something like below.

public IHttpActionResult Put([FromBody] string name){ ... }

This asp.net page explains it all. http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

Without using JMX, which is what most tools use, all you can do is use

jps -lvm

and infer that the settings will be from the command line options.

You can't get dynamic information without JMX by default but you could write your own service to do this.

BTW: I prefer to use VisualVM rather than JConsole.

If you want difference of two timestamp into total days,hours and minutes only, not in months and years .

var now  = "01/08/2016 15:00:00";
var then = "04/02/2016 14:20:30";
var diff = moment.duration(moment(then).diff(moment(now)));

diff contains 2 months,23 days,23 hours and 20 minutes. But we need result only in days,hours and minutes so the simple solution is:

var days = parseInt(diff.asDays()); //84

var hours = parseInt(diff.asHours()); //2039 hours, but it gives total hours in given miliseconds which is not expacted.

hours = hours - days*24;  // 23 hours

var minutes = parseInt(diff.asMinutes()); //122360 minutes,but it gives total minutes in given miliseconds which is not expacted.

minutes = minutes - (days*24*60 + hours*60); //20 minutes.

Final result will be : 84 days, 23 hours, 20 minutes.

Please check: http://man7.org/linux/man-pages/man5/proc.5.html

address           perms offset  dev   inode       pathname
00400000-00452000 r-xp 00000000 08:02 173521      /usr/bin/dbus-daemon

The address field is the address space in the process that the mapping occupies.

The perms field is a set of permissions:

 r = read
 w = write
 x = execute
 s = shared
 p = private (copy on write)

The offset field is the offset into the file/whatever;

dev is the device (major:minor);

inode is the inode on that device.0 indicates that no inode is associated with the memoryregion, as would be the case with BSS (uninitialized data).

The pathname field will usually be the file that is backing the mapping. For ELF files, you can easily coordinate with the offset field by looking at the Offset field in the ELF program headers (readelf -l).

Under Linux 2.0, there is no field giving pathname.

Open phpMyAdmin and select the SQL tab. Then type this command:

Easiest way to fetch any initialize use ng-init directory.

NOTE: you can use this methodology if you do not have same code more then one place.

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

• If it looks ugly, just remove the unnecessary ToCharArray call.

• If you want to split by either \n or \r, you've got two options:

  • Use an array literal – but this will give you empty lines for Windows-style line endings \r\n:

    var result = text.Split(new [] { '\r', '\n' });
    

  • Use a regular expression, as indicated by Bart:

    var result = Regex.Split(text, "\r\n|\r|\n");
    

• If you want to preserve empty lines, why do you explicitly tell C# to throw them away? (StringSplitOptions parameter) – use StringSplitOptions.None instead.

If the image is proportionate then this code will fill the wrapper with image. If image is not in proportion then extra width/height will get cropped.

    <script type="text/javascript">
        $(function(){
            $('#slider img').each(function(){
                var ReqWidth = 1000; // Max width for the image
                var ReqHeight = 300; // Max height for the image
                var width = $(this).width(); // Current image width
                var height = $(this).height(); // Current image height
                // Check if the current width is larger than the max
                if (width > height && height < ReqHeight) {

                    $(this).css("min-height", ReqHeight); // Set new height
                }
                else 
                    if (width > height && width < ReqWidth) {

                        $(this).css("min-width", ReqWidth); // Set new width
                    }
                    else 
                        if (width > height && width > ReqWidth) {

                            $(this).css("max-width", ReqWidth); // Set new width
                        }
                        else 
                            (height > width && width < ReqWidth)
                {

                    $(this).css("min-width", ReqWidth); // Set new width
                }
            });
        });
    </script>

Simply invoke orderBy() as many times as you need it. For instance:

User::orderBy('name', 'DESC')
    ->orderBy('email', 'ASC')
    ->get();

Produces the following query:

SELECT * FROM `users` ORDER BY `name` DESC, `email` ASC

From Git documentation:

-m <msg>
--message=<msg>
Use the given <msg> as the commit message. If multiple -m options are given, their values are concatenated as separate paragraphs.

So, if you are looking for grouping multiple commit messages this should do the work:

git commit -m "commit message1" -m "commit message2"

On ReactNative .53, the following works for me:

 this.timeoutCheck = setTimeout(() => {
   this.setTimePassed();
   }, 400);

'setTimeout' is the ReactNative library function.
'this.timeoutCheck' is my variable to hold the time out object.
'this.setTimePassed' is my function to invoke at the time out.

python: urllib2 how to send cookie with urlopen request

import urllib2
import urllib
from cookielib import CookieJar

cj = CookieJar()
opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
# input-type values from the html form
formdata = { "username" : username, "password": password, "form-id" : "1234" }
data_encoded = urllib.urlencode(formdata)
response = opener.open("https://page.com/login.php", data_encoded)
content = response.read()

EDIT:

I see I've gotten a few downvotes for my answer, but no explaining comments. I'm guessing it's because I'm referring to the urllib libraries instead of requests. I do that because the OP asks for help with requests or for someone to suggest another approach.

GNU Trove support this but not using generics. http://trove4j.sourceforge.net/javadocs/gnu/trove/TObjectIntHashMap.html

I've used min-height: 100vh; with great success on some of my projects. See example.

Yes, there are special server side comments:

<%-- Text not sent to client  --%>

For HTML 4, the answer is technically:

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

HTML 5 is even more permissive, saying only that an id must contain at least one character and may not contain any space characters.

The id attribute is case sensitive in XHTML.

As a purely practical matter, you may want to avoid certain characters. Periods, colons and '#' have special meaning in CSS selectors, so you will have to escape those characters using a backslash in CSS or a double backslash in a selector string passed to jQuery. Think about how often you will have to escape a character in your stylesheets or code before you go crazy with periods and colons in ids.

For example, the HTML declaration <div id="first.name"></div> is valid. You can select that element in CSS as #first\.name and in jQuery like so: $('#first\\.name'). But if you forget the backslash, $('#first.name'), you will have a perfectly valid selector looking for an element with id first and also having class name. This is a bug that is easy to overlook. You might be happier in the long run choosing the id first-name (a hyphen rather than a period), instead.

You can simplify your development tasks by strictly sticking to a naming convention. For example, if you limit yourself entirely to lower-case characters and always separate words with either hyphens or underscores (but not both, pick one and never use the other), then you have an easy-to-remember pattern. You will never wonder "was it firstName or FirstName?" because you will always know that you should type first_name. Prefer camel case? Then limit yourself to that, no hyphens or underscores, and always, consistently use either upper-case or lower-case for the first character, don't mix them.

A now very obscure problem was that at least one browser, Netscape 6, incorrectly treated id attribute values as case-sensitive. That meant that if you had typed id="firstName" in your HTML (lower-case 'f') and #FirstName { color: red } in your CSS (upper-case 'F'), that buggy browser would have failed to set the element's color to red. At the time of this edit, April 2015, I hope you aren't being asked to support Netscape 6. Consider this a historical footnote.

Mail.dll email component includes email template engine:

Here's the syntax overview:

<html>
<body>
Hi {FirstName} {LastName},

Here are your orders: 
{foreach Orders}
    Order '{Name}' sent to <strong>{Street}</strong>. 
{end}

</body>
</html>

And the code that loads the template, fills data from c# object and sends an email:

Mail.Html(Template
              .FromFile("template.txt")
              .DataFrom(_contact)
              .Render())
    .Text("This is text version of the message.")
    .From(new MailBox("[email protected]", "Alice"))
    .To(new MailBox("[email protected]", "Bob"))
    .Subject("Your order")
    .UsingNewSmtp()
    .WithCredentials("[email protected]", "password")
    .Server("mail.com")
    .WithSSL()
    .Send();

You can get more info on email template engine blog post.

Or just download Mail.dll email component and give it a try.

Please note that this is a commercial product I've created.

if there are multiple java processes and you wish to kill them with one command try the below command

kill -9 $(ps -ef | pgrep -f "java")

replace "java" with any process string identifier , to kill anything else.

string cannot be the parameter to Nullable because string is not a value type. String is a reference type.

string s = null; 

is a very valid statement and there is not need to make it nullable.

private string typeOfContract
    {
      get { return ViewState["typeOfContract"] as string; }
      set { ViewState["typeOfContract"] = value; }
    }

should work because of the as keyword.

Manually resolving instances involves using the IServiceProvider interface:

Resolving Dependency in Startup.ConfigureServices

public void ConfigureServices(IServiceCollection services)
{
    services.AddTransient<IMyService, MyService>();

    var serviceProvider = services.BuildServiceProvider();
    var service = serviceProvider.GetService<IMyService>();
}

Resolving Dependencies in Startup.Configure

public void Configure(
    IApplicationBuilder application,
    IServiceProvider serviceProvider)
{
    // By type.
    var service1 = (MyService)serviceProvider.GetService(typeof(MyService));

    // Using extension method.
    var service2 = serviceProvider.GetService<MyService>();

    // ...
}

Resolving Dependencies in Startup.Configure in ASP.NET Core 3

public void Configure(
    IApplicationBuilder application,
    IWebHostEnvironment webHostEnvironment)
{
    application.ApplicationServices.GetService<MyService>();
}

Using Runtime Injected Services

Some types can be injected as method parameters:

public class Startup
{
    public Startup(
        IHostingEnvironment hostingEnvironment,
        ILoggerFactory loggerFactory)
    {
    }

    public void ConfigureServices(
        IServiceCollection services)
    {
    }

    public void Configure(
        IApplicationBuilder application,
        IHostingEnvironment hostingEnvironment,
        IServiceProvider serviceProvider,
        ILoggerFactory loggerfactory,
        IApplicationLifetime applicationLifetime)
    {
    }
}

Resolving Dependencies in Controller Actions

[HttpGet("/some-action")]
public string SomeAction([FromServices] IMyService myService) => "Hello";

Think about your user interface before you do this. I assume (though none of the answers has said so) that you'll be doing this when the document loads using jQuery's ready() function. If a user has already focussed on a different element before the document has loaded (which is perfectly possible) then it's extremely irritating for them to have the focus stolen away.

You could check for this by adding onfocus attributes in each of your <input> elements to record whether the user has already focussed on a form field and then not stealing the focus if they have:

var anyFieldReceivedFocus = false;

function fieldReceivedFocus() {
    anyFieldReceivedFocus = true;
}

function focusFirstField() {
    if (!anyFieldReceivedFocus) {
        // Do jQuery focus stuff
    }
}


<input type="text" onfocus="fieldReceivedFocus()" name="one">
<input type="text" onfocus="fieldReceivedFocus()" name="two">

Another way of solving this problem is using Reactive Extensions:

public static Task TimeoutAfter(this Task task, TimeSpan timeout, IScheduler scheduler)
{
        return task.ToObservable().Timeout(timeout, scheduler).ToTask();
}

Test up above using below code in your unit test, it works for me

TestScheduler scheduler = new TestScheduler();
Task task = Task.Run(() =>
                {
                    int i = 0;
                    while (i < 5)
                    {
                        Console.WriteLine(i);
                        i++;
                        Thread.Sleep(1000);
                    }
                })
                .TimeoutAfter(TimeSpan.FromSeconds(5), scheduler)
                .ContinueWith(t => { }, TaskContinuationOptions.OnlyOnFaulted);

scheduler.AdvanceBy(TimeSpan.FromSeconds(6).Ticks);

You may need the following namespace:

using System.Threading.Tasks;
using System.Reactive.Subjects;
using System.Reactive.Linq;
using System.Reactive.Threading.Tasks;
using Microsoft.Reactive.Testing;
using System.Threading;
using System.Reactive.Concurrency;

Use Like below

<input type="file" accept=".xlsx,.xls,image/*,.doc, .docx,.ppt, .pptx,.txt,.pdf" />

there should has a concurrent implemention of List interface supporting such operation.

try java.util.concurrent.CopyOnWriteArrayList.class

Create a function to move it:

function move_file($file, $to){
    $path_parts = pathinfo($file);
    $newplace   = "$to/{$path_parts['basename']}";
    if(rename($file, $newplace))
        return $newplace;
    return null;
}

Python doesn't have the quite the extensive range of "built-in" data structures as Java does. However, because Python is dynamic, a general tree is easy to create. For example, a binary tree might be:

class Tree:
    def __init__(self):
        self.left = None
        self.right = None
        self.data = None

You can use it like this:

root = Tree()
root.data = "root"
root.left = Tree()
root.left.data = "left"
root.right = Tree()
root.right.data = "right"

If you need an arbitrary number of children per node, then use a list of children:

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

left = Tree("left")
middle = Tree("middle")
right = Tree("right")
root = Tree("root")
root.children = [left, middle, right]

in pyspark you can do this:

max(df.select('ColumnName').rdd.flatMap(lambda x: x).collect())

An easy way to implement multiple field comparisons is with Guava's ComparisonChain - then you can say

   public int compareTo(Foo that) {
     return ComparisonChain.start()
         .compare(lastName, that.lastName)
         .compare(firstName, that.firstName)
         .compare(zipCode, that.zipCode)
         .result();
   }

instead of

  public int compareTo(Person other) {
    int cmp = lastName.compareTo(other.lastName);
    if (cmp != 0) {
      return cmp;
    }
    cmp = firstName.compareTo(other.firstName);
    if (cmp != 0) {
      return cmp;
    }
    return Integer.compare(zipCode, other.zipCode);
  }
}

This is the code I'm using. Also works for .NET Core > 2.0 using System.Drawing.Common NuGet.

https://www.nuget.org/packages/System.Drawing.Common/

using System;
using System.Drawing;

class Program
{
    static void Main()
    {
        const string input = "C:\\background1.png";
        const string output = "C:\\thumbnail.png";

        // Load image.
        Image image = Image.FromFile(input);

        // Compute thumbnail size.
        Size thumbnailSize = GetThumbnailSize(image);

        // Get thumbnail.
        Image thumbnail = image.GetThumbnailImage(thumbnailSize.Width,
            thumbnailSize.Height, null, IntPtr.Zero);

        // Save thumbnail.
        thumbnail.Save(output);
    }

    static Size GetThumbnailSize(Image original)
    {
        // Maximum size of any dimension.
        const int maxPixels = 40;

        // Width and height.
        int originalWidth = original.Width;
        int originalHeight = original.Height;

        // Return original size if image is smaller than maxPixels
        if (originalWidth <= maxPixels || originalHeight <= maxPixels)
        {
            return new Size(originalWidth, originalHeight);
        }   

        // Compute best factor to scale entire image based on larger dimension.
        double factor;
        if (originalWidth > originalHeight)
        {
            factor = (double)maxPixels / originalWidth;
        }
        else
        {
            factor = (double)maxPixels / originalHeight;
        }

        // Return thumbnail size.
        return new Size((int)(originalWidth * factor), (int)(originalHeight * factor));
    }
}

Try:

var count = $('#gvPerformanceResult tr').length;

I was running into this issue that when I run docker rm (which usually works) I would get:

Error: No such image

The easiest solution to this is removing all stopped containers by running:

docker container prune

Use PropertyInfo.PropertyType to get the type of the property.

public bool ValidateData(object data)
{
    foreach (PropertyInfo propertyInfo in data.GetType().GetProperties())
    {
        if (propertyInfo.PropertyType == typeof(string))
        {
            string value = propertyInfo.GetValue(data, null);

            if value is not OK
            {
                return false;
            }
        }
    }            

    return true;
}

For renaming your index you can use Elasticsearch Snapshot module.

First you have to take snapshot of your index.while restoring it you can rename your index.

    POST /_snapshot/my_backup/snapshot_1/_restore
    {
     "indices": "jal",
     "ignore_unavailable": "true",
     "include_global_state": false,
     "rename_pattern": "jal",
     "rename_replacement": "jal1"
     }

rename_replacement :-New indexname in which you want backup your data.

A File object in Java is a representation of a path to a directory or file, not the file itself. You don't need to have write access to the filesystem to create a File object, you only need it if you intend to actually write to the file (using a FileOutputStream for example)

Please check this jQuery plugin,

blockUI

with this you can overlay all the page or elements, works great for me,

Examples: Block a div: $('div.test').block({ message: null });

Block the page: $.blockUI({ message: '<h1><img src="busy.gif" /> Just a moment...</h1>' }); Hope that help someone

I solved the problem by uninstalling NodeJs and gulp then re-installing both again.

To install gulp globally I executed the following command

npm install -g gulp

Note that in PHP 7.4, money_format() function is deprecated. It can be replaced by the intl NumberFormatter functionality, just make sure you enable the php-intl extension. It's a small amount of effort and worth it as you get a lot of customizability.

$f = new NumberFormatter("en", NumberFormatter::CURRENCY);
$f->formatCurrency(12345, "USD"); // Outputs "$12,345.00"

The fast way that will still work for 7.4 is as mentioned by Darryl Hein:

'$' . number_format($money, 2);

assume min and max are int values, [ and ] means include this value, ( and ) means not include this value, using above to get the right value using c++ rand()

reference: for ()[] define, visit:

https://en.wikipedia.org/wiki/Interval_(mathematics)

for rand and srand function or RAND_MAX define, visit:

http://en.cppreference.com/w/cpp/numeric/random/rand

[min, max]

int randNum = rand() % (max - min + 1) + min

(min, max]

int randNum = rand() % (max - min) + min + 1

[min, max)

int randNum = rand() % (max - min) + min

(min, max)

int randNum = rand() % (max - min - 1) + min + 1

$_SERVER['REQUEST_TIME']

check out that too. i.e.

...
// your codes running
...
echo (time() - $_SERVER['REQUEST_TIME']);

Note also that vertical-align:top; is often necessary for correct table cell appearance.

css table-cell, contents have unnecessary top margin

I use moment.js http://momentjs.com/

var start = moment(StartTimeString).toDate().getTime();
var end = moment(EndTimeString).toDate().getTime();
var timespan = end - start;
var duration = moment(timespan);
var output = duration.format("YYYY-MM-DDTHH:mm:ss");

As Sayse mentioned, exit code 259 (0x103) has special meaning, in this case the process being debugged is still running.

I saw this a lot with debugging web services, because the thread continues to run after executing each web service call (as it is still listening for further calls).

The problem with 500 errors (with CodeIgniter), with different apache settings, it displays 500 error when there's an error with PHP configuration.

Here's how it can trigger 500 error with CodeIgniter:

1. Error in script (PHP misconfigurations, missing packages, etc...)
2. PHP "Fatal Errors"

Please check your apache error logs, there should be some interesting information in there.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

I searched a long night and this is doing the trick:

Modified user-example.php from admin-sdk

$client->setAccessType('offline');
$client->setApprovalPrompt('force');
$authUrl = $client->createAuthUrl();
echo "<a class='login' href='" . $authUrl . "'>Connect Me!</a>";

then you get the code at the redirect url and the authenticating with the code and getting the refresh token

$client()->authenticate($_GET['code']);
echo $client()->getRefreshToken();

You should store it now ;)

When your accesskey times out just do

$client->refreshToken($theRefreshTokenYouHadStored);

Do you mean you only want the alphabetic characters and not the digits? So you want "quality" as a result? You can use Char.IsLetter or Char.IsDigit to filter them out one by one.

string s = "9quali52ty3";
StringBuilder result = new StringBuilder();
foreach(char c in s)
{
  if (Char.IsLetter(c))  
    result.Add(c);
}
Console.WriteLine(result);  // quality

SELECT * FROM items WHERE `items.xml` LIKE '%123456%'

The % operator in LIKE means "anything can be here".

If you need in different Layer :

Create a Static Class and expose all config properties on that layer as below :

using Microsoft.Extensions.Configuration;_x000D_
using System.IO;_x000D_
_x000D_
namespace Core.DAL_x000D_
{_x000D_
    public static class ConfigSettings_x000D_
    {_x000D_
        public static string conStr1 { get ; }_x000D_
        static ConfigSettings()_x000D_
        {_x000D_
            var configurationBuilder = new ConfigurationBuilder();_x000D_
            string path = Path.Combine(Directory.GetCurrentDirectory(), "appsettings.json");_x000D_
            configurationBuilder.AddJsonFile(path, false);_x000D_
            conStr1 = configurationBuilder.Build().GetSection("ConnectionStrings:ConStr1").Value;_x000D_
        }_x000D_
    }_x000D_
}

So if you just have a string and not a window.location you could use...

String.prototype.toUrl = function(){

if(!this && 0 < this.length)
{
    return undefined;
}
var original = this.toString();
var s = original;
if(!original.toLowerCase().startsWith('http'))
{
    s = 'http://' + original;
}

s = this.split('/');

var protocol = s[0];
var host = s[2];
var relativePath = '';

if(s.length > 3){
    for(var i=3;i< s.length;i++)
    {
        relativePath += '/' + s[i];
    }
}

s = host.split('.');
var domain = s[s.length-2] + '.' + s[s.length-1];    

return {
    original: original,
    protocol: protocol,
    domain: domain,
    host: host,
    relativePath: relativePath,
    getParameter: function(param)
    {
        return this.getParameters()[param];
    },
    getParameters: function(){
        var vars = [], hash;
        var hashes = this.original.slice(this.original.indexOf('?') + 1).split('&');
        for (var i = 0; i < hashes.length; i++) {
            hash = hashes[i].split('=');
            vars.push(hash[0]);
            vars[hash[0]] = hash[1];
        }
        return vars;
    }
};};

How to use.

var str = "http://en.wikipedia.org/wiki/Knopf?q=1&t=2";
var url = str.toUrl;

var host = url.host;
var domain = url.domain;
var original = url.original;
var relativePath = url.relativePath;
var paramQ = url.getParameter('q');
var paramT = url.getParamter('t');

This is totally covered by the other answers, but I'll make it explicit. An object may have class attributes and static and dynamic instance attributes.

class foo:
    classy = 1
    @property
    def dyno(self):
        return 1
    def __init__(self):
        self.stasis = 2

    def fx(self):
        return 3

stasis is static, dyno is dynamic (cf. property decorator) and classy is a class attribute. If we simply do __dict__ or vars we will only get the static one.

o = foo()
print(o.__dict__) #{'stasis': 2}
print(vars(o)) #{'stasis': 2}

So if we want the others __dict__ will get everything (and more). This includes magic methods and attributes and normal bound methods. So lets avoid those:

d = {k: getattr(o, k, '') for k in o.__dir__() if k[:2] != '__' and type(getattr(o, k, '')).__name__ != 'method'}
print(d) #{'stasis': 2, 'classy': 1, 'dyno': 1}

The type called with a property decorated method (a dynamic attribute) will give you the type of the returned value, not method. To prove this let's json stringify it:

import json
print(json.dumps(d)) #{"stasis": 2, "classy": 1, "dyno": 1}

Had it been a method it would have crashed.

TL;DR. try calling extravar = lambda o: {k: getattr(o, k, '') for k in o.__dir__() if k[:2] != '__' and type(getattr(o, k, '')).__name__ != 'method'} for all three, but not methods nor magic.
