Programs & Examples On #Case

Thanks for all your help! @Svetoslav Tsolov had it very close, but I was still getting an error, until I figured out the closing parenthesis was in the wrong place. Here's the final query that works:

SELECT dbo.AdminID.CountryID, dbo.AdminID.CountryName, dbo.AdminID.RegionID, 
dbo.AdminID.[Region name], dbo.AdminID.DistrictID, dbo.AdminID.DistrictName,
dbo.AdminID.ADMIN3_ID, dbo.AdminID.ADMIN3,
(CASE WHEN dbo.EU_Admin3.EUID IS NULL THEN dbo.EU_Admin2.EUID ELSE dbo.EU_Admin3.EUID END) AS EUID
FROM dbo.AdminID 

LEFT OUTER JOIN dbo.EU_Admin2
ON dbo.AdminID.DistrictID = dbo.EU_Admin2.DistrictID

LEFT OUTER JOIN dbo.EU_Admin3
ON dbo.AdminID.ADMIN3_ID = dbo.EU_Admin3.ADMIN3_ID

You can't use a condition to change the structure of your query, just the data involved. You could do this:

update table set
    columnx = (case when condition then 25 else columnx end),
    columny = (case when condition then columny else 25 end)

This is semantically the same, but just bear in mind that both columns will always be updated. This probably won't cause you any problems, but if you have a high transactional volume, then this could cause concurrency issues.

The only way to do specifically what you're asking is to use dynamic SQL. This is, however, something I'd encourage you to stay away from. The solution above will almost certainly be sufficient for what you're after.

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

      ( (@url IS null OR @url = '' OR @url = 'ALL') and   PurchasingWebServiceURL LIKE '%')
    or

       ( @url = 'blank' and  PurchasingWebServiceURL = '')
    or
        (@url = 'fail' and  PurchasingWebServiceURL NOT LIKE '%treyresearch%')
    or( (@url not in ('fail','blank','','ALL') and @url is not null and 
          PurchasingWebServiceUrl Like '%'+@ur+'%') 
END

LCASE or UCASE respectively.

Example:

SELECT UCASE(MyColumn) AS Upper, LCASE(MyColumn) AS Lower
FROM MyTable

I think I found the answer:

convert(nvarchar(50), RequestID)

Here's the link where I found this info:

http://msdn.microsoft.com/en-us/library/ms187928.aspx

CASE course_enrollment_settings.base_price is wrong here, it should be just CASE

SELECT 
CASE 
WHEN course_enrollment_settings.base_price = 0      THEN 1 
WHEN course_enrollment_settings.base_price<101      THEN 2 
WHEN course_enrollment_settings.base_price>100 AND    
                  course_enrollment_settings.base_price<201 THEN 3 
    ELSE 6 
END AS 'calc_base_price', 
course_enrollment_settings.base_price 
FROM 
  course_enrollment_settings 
WHERE course_enrollment_settings.base_price = 0 

Some explanations. Your original query will be executed as :

SELECT 
CASE 0
WHEN 0=0 THEN 1 -- condition evaluates to 1, then 0 (from CASE 0)compares to 1 - false
WHEN 0<1 THEN 2 -- condition evaluates to 1,then 0 (from CASE 0)compares to 1 - false
WHEN 0>100 and 0<201 THEN 3 -- evaluates to 0 ,then 0 (from CASE 0)compares to 0 - true
ELSE 6, ...

it's why you always get 3

If all the cases have the same length you can use
switch (mystring.SubString(0,Math.Min(len, mystring.Length))).
Another option is to have a function that will return categoryId based on the string and switch on the id.

I am looking for a way to create a select without repeating the conditional query.

I'm assuming that you don't want to repeat Foo-stuff+bar. You could put your calculation into a derived table:

SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END 
FROM (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable) AS a

A common table expression would work just as well:

WITH a AS (SELECT (Foo-stuff+bar) AS TestValue FROM MyTable)
SELECT CASE WHEN a.TestValue > 2 THEN a.TestValue ELSE 'Fail' END    
FROM a

Also, each part of your switch should return the same datatype, so you may have to cast one or more cases.

The MSDN is a good reference for these type of questions regarding syntax and usage. This is from the Transact SQL Reference - CASE page.

http://msdn.microsoft.com/en-us/library/ms181765.aspx

USE AdventureWorks2012;
GO
SELECT   ProductNumber, Name, "Price Range" = 
  CASE 
     WHEN ListPrice =  0 THEN 'Mfg item - not for resale'
     WHEN ListPrice < 50 THEN 'Under $50'
     WHEN ListPrice >= 50 and ListPrice < 250 THEN 'Under $250'
     WHEN ListPrice >= 250 and ListPrice < 1000 THEN 'Under $1000'
     ELSE 'Over $1000'
  END
FROM Production.Product
ORDER BY ProductNumber ;
GO

Another good site you may want to check out if you're using SQL Server is SQL Server Central. This has a large variety of resources available for whatever area of SQL Server you would like to learn.

I actually prefer the approach given as the answer here: Is there a better alternative than this to 'switch on type'?

There is however a good argument about not implementing any type comparison methids in an object oriented language like C#. You could as an alternative extend and add extra required functionality using inheritance.

This point was discussed in the comments of the authors blog here: http://blogs.msdn.com/b/jaredpar/archive/2008/05/16/switching-on-types.aspx#8553535

I found this an extremely interesting point which changed my approach in a similar situation and only hope this helps others.

Kind Regards, Wayne

That format requires you to use either:

CASE ebv.db_no 
  WHEN 22978 THEN 'WECS 9500' 
  WHEN 23218 THEN 'WECS 9500'  
  WHEN 23219 THEN 'WECS 9500' 
  ELSE 'WECS 9520' 
END as wecs_system 

Otherwise, use:

CASE  
  WHEN ebv.db_no IN (22978, 23218, 23219) THEN 'WECS 9500' 
  ELSE 'WECS 9520' 
END as wecs_system 

Separate the business rules for age from the actions e.g. (NB just typed, not checked)

enum eAgerange { eChild, eYouth, eAdult, eAncient};
eAgeRange ar;
if(age <= 8) ar = eChild;
else if(age <= 15) ar = eYouth;
else if(age <= 100) ar = eAdult;
else ar = eAncient;
switch(ar)
{
 case eChild: 
     // action
 case eYouth:
     // action
 case eAdult:
     // action
 case eAncient:
     // action
 default: throw new NotImplementedException($"Oops {ar.ToString()} not handled");
}

Yeah, But not in a normal way. You will have to use switch as closure.

ex:-

function test(input1, input2) {
     switch (true) {
        case input1 > input2:
                    console.log(input1 + " is larger than " + input2);
                    break;
        case input1 < input2:
                    console.log(input2 + " is larger than " + input1);
        default:
                    console.log(input1 + " is equal to " + input2);
      }
   }

Try this:

WHERE a.Country = (CASE WHEN @Country > 0 THEN @Country ELSE a.Country END)

This is just the syntax of the case statement, it looks like this.

SELECT 
  CASE 
    WHEN FRUIT = 'A' THEN 'APPLE' 
    WHEN FRUIT = 'B' THEN 'BANANA'     
  END AS FRUIT
FROM FRUIT_TABLE;

As a reminder remember; no assignment is performed the value becomes the column contents. (If you wanted to assign that to a variable you would put it before the CASE statement).

Crosstab function is available under the tablefunc extension. You'll have to create this extension one time for the database.

CREATE EXTENSION tablefunc;

You can use the below code to create pivot table using cross tab:

create table test_Crosstab( section text,
<br/>status text,
<br/>count numeric)

<br/>insert into test_Crosstab values ( 'A','Active',1)
                <br/>,( 'A','Inactive',2)
                <br/>,( 'B','Active',4)
                <br/>,( 'B','Inactive',5)

select * from crosstab(
<br/>'select section
    <br/>,status
    <br/>,count
    <br/>from test_crosstab'
    <br/>)as ctab ("Section" text,"Active" numeric,"Inactive" numeric)

MySQL also has IF():

SELECT 
  id, action_heading, 
      IF(action_type='Income',action_amount,0) income, 
      IF(action_type='Expense', action_amount, 0) expense
FROM tbl_transaction

is null can be used to check whether null data is coming from a query as in following example:

 declare @Mem varchar(20),@flag int
select @mem=MemberClub from [dbo].[UserMaster] where UserID=@uid
if(@Mem is null)
begin
    set @flag= 0;
end
else
begin
    set @flag=1;
end
return @flag;

A new feature, IIF (that we can simply use), was added in SQL Server 2012:

SELECT IIF ( (Obsolete = 'N' OR InStock = 'Y'), 1, 0) AS Saleable, * FROM Product

I suggest you not use literals.

Other than that the style itself looks fine.

Try

switch($value) {
    case 1:
    case 2:
        echo "the value is either 1 or 2";
        break;
}

You are mixing the 2 different CASE syntaxes inappropriately.

Use this style (Searched)

  CASE  
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Or this style (Simple)

  CASE u.nnmu 
  WHEN '0' THEN mu.naziv_mesta
  WHEN '1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

Not This (Simple but with boolean search predicates)

  CASE u.nnmu 
  WHEN u.nnmu ='0' THEN mu.naziv_mesta
  WHEN u.nnmu ='1' THEN m.naziv_mesta
 ELSE 'GRESKA'
 END as mesto_utovara,

In MySQL this will end up testing whether u.nnmu is equal to the value of the boolean expression u.nnmu ='0' itself. Regardless of whether u.nnmu is 1 or 0 the result of the case expression itself will be 1

For example if nmu = '0' then (nnmu ='0') evaluates as true (1) and (nnmu ='1') evaluates as false (0). Substituting these into the case expression gives

 SELECT CASE  '0'
  WHEN 1 THEN '0'
  WHEN 0 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

if nmu = '1' then (nnmu ='0') evaluates as false (0) and (nnmu ='1') evaluates as true (1). Substituting these into the case expression gives

 SELECT CASE  '1'
  WHEN 0 THEN '0'
  WHEN 1 THEN '1'
 ELSE 'GRESKA'
 END as mesto_utovara

You could also try like below eg. to show only Outbound Shipments

   SELECT shp_awb_no,shpr_ctry_cd, recvr_ctry_cd,
     CASE WHEN shpr_ctry_cd = record_ctry_cd 
     THEN "O" 
     ELSE "I" 
      END AS route
     FROM shipment_details
    WHERE record_ctry_cd = "JP"
      AND "O" = CASE WHEN shpr_ctry_cd = record_ctry_cd 
                THEN "O" 
                ELSE "I" 
                 END

select  ISNULL(CONVERT(VARCHAR(23), WorkingDate,121),'') from uv_Employee

SELECT *
FROM ...
WHERE EXISTS(SELECT 1 
        FROM sys.columns c
        WHERE c.[object_id] = OBJECT_ID('dbo.Tags')
            AND c.name = 'ModifiedByUser'
    )

Try this:

...JOIN sys.allocation_units a ON 
  (a.type=2 AND a.container_id = p.partition_id)
  OR (a.type IN (1, 3) AND a.container_id = p.hobt_id)

Try this query, it's very easy and useful: Its ready to execute!

USE tempdb
GO

IF NOT OBJECT_ID('Tempdb..Contacts') IS NULL
    DROP TABLE Contacts

CREATE TABLE Contacts(ID INT, FirstName VARCHAR(100), LastName VARCHAR(100))
INSERT INTO Contacts (ID, FirstName, LastName)
SELECT 1, 'Omid', 'Karami'
UNION ALL
SELECT 2, 'Alen', 'Fars'
UNION ALL
SELECT 3, 'Sharon', 'b'
UNION ALL
SELECT 4, 'Poja', 'Kar'
UNION ALL
SELECT 5, 'Ryan', 'Lasr'
GO
 
DECLARE @FirstName VARCHAR(100)
SET @FirstName = 'Omid'
 
DECLARE @LastName VARCHAR(100)
SET @LastName = '' 
 
SELECT FirstName, LastName
FROM Contacts
WHERE  
    FirstName = CASE
    WHEN LEN(@FirstName) > 0 THEN  @FirstName 
    ELSE FirstName 
    END
AND
    LastName = CASE
    WHEN LEN(@LastName) > 0 THEN  @LastName 
    ELSE LastName
    END
GO

I dug up the Oracle page for the same and it looks like this is the same syntax, just described slightly different.

Link: Oracle/PLSQL: Case Statement

**//With the help of this code u not just sort the arrays in alphabetical order but also can take string from user or console or keyboard

import java.util.Scanner;
import java.util.Arrays;
public class ReadName
{
final static int ARRAY_ELEMENTS = 3;
public static void main(String[] args)
{
String[] theNames = new String[5];
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the names: ");
for (int i=0;i<theNames.length ;i++ )
{           
theNames[i] = keyboard.nextLine();
}
System.out.println("**********************");
Arrays.sort(theNames);
for (int i=0;i<theNames.length ;i++ )
{
System.out.println("Name are " + theNames[i]);
}
}
}**

Also, you do not have to use nested CASEs. You can use several WHEN-THEN lines and the ELSE line is also optional eventhough I recomend it

CASE 
   WHEN [condition.1] THEN [expression.1]
   WHEN [condition.2] THEN [expression.2]
   ...
   WHEN [condition.n] THEN [expression.n]
   ELSE [expression] 
END

Aliases can be used only if they were introduced in the preceding step. So aliases in the SELECT clause can be used in the ORDER BY but not the GROUP BY clause.

Reference: Microsoft T-SQL Documentation for further reading.

FROM
ON
JOIN
WHERE
GROUP BY
WITH CUBE or WITH ROLLUP
HAVING
SELECT
DISTINCT
ORDER BY
TOP

Hope this helps.

You should avoid using nested selects and I would go as far to say you should never use them in the actual select part of your statement. You will be running that select for each row that is returned. This is a really expensive operation. Rather use joins. It is much more readable and the performance is much better.

In your case the query below should help. Note the cases statement is still there, but now it is a simple compare operation.

select
    p.product_id,
    p.type_id,
    p.product_name,
    p.type,
    case p.type_id when 10 then (CONCAT_WS(' ' , first_name, middle_name, last_name )) else (null) end artistC
from
    Product p

    inner join Product_Type pt on
        pt.type_id = p.type_id

    left join Product_ArtistAuthor paa on
        paa.artist_id = p.artist_id
where
    p.product_id = $pid

I used a left join since I don't know the business logic.

Another way of doing this is using nested IF statements. Suppose you have companies table and you want to count number of records in it. A sample query would be something like this

SELECT IF(
      count(*) > 15,
      'good',
      IF(
          count(*) > 10,
          'average',
          'poor'
        ) 
      ) as data_count 
      FROM companies

Here second IF condition works when the first IF condition fails. So Sample Syntax of the IF statement would be IF ( CONDITION, THEN, ELSE). Hope it helps someone.

Use an "Or"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where (CPaymentType='Check' Or CPaymentType='Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

or an "IN"

Select SUM(CAmount) as PaymentAmount 
from TableOrderPayment 
where CPaymentType IN ('Check', 'Cash')
   and CDate <= case CPaymentType When 'Check' Then SYSDATETIME() else CDate End
   and CStatus='" & "Active" & "'"

IIF is the same as CASE WHEN <Condition> THEN <true part> ELSE <false part> END. The query plan will be the same. It is, perhaps, "syntactical sugar" as initially implemented.

CASE is portable across all SQL platforms whereas IIF is SQL SERVER 2012+ specific.

CASE in MySQL is both a statement and an expression, where each usage is slightly different.

As a statement, CASE works much like a switch statement and is useful in stored procedures, as shown in this example from the documentation (linked above):

DELIMITER |

CREATE PROCEDURE p()
  BEGIN
    DECLARE v INT DEFAULT 1;

    CASE v
      WHEN 2 THEN SELECT v;
      WHEN 3 THEN SELECT 0;
      ELSE
        BEGIN -- Do other stuff
        END;
    END CASE;
  END;
  |

However, as an expression it can be used in clauses:

SELECT *
  FROM employees
  ORDER BY
    CASE title
      WHEN "President" THEN 1
      WHEN "Manager" THEN 2
      ELSE 3
    END, surname

Additionally, both as a statement and as an expression, the first argument can be omitted and each WHEN must take a condition.

SELECT *
  FROM employees
  ORDER BY
    CASE 
      WHEN title = "President" THEN 1
      WHEN title = "Manager" THEN 2
      ELSE 3
    END, surname

I provided this answer because the other answer fails to mention that CASE can function both as a statement and as an expression. The major difference between them is that the statement form ends with END CASE and the expression form ends with just END.

Please select the same in the outer select. You can't access the alias name in the same query.

SELECT *, (CASE
        WHEN articleNumber < 2 THEN 'Ama'
        WHEN articleNumber < 5 THEN 'SemiAma' 
        WHEN articleNumber < 7 THEN 'Good'  
        WHEN articleNumber < 9 THEN 'Better' 
        WHEN articleNumber < 12 THEN 'Best'
        ELSE 'Outstanding'
        END) AS ranking 
FROM(
    SELECT registrationDate, (SELECT COUNT(*) FROM Articles WHERE Articles.userId = Users.userId) as articleNumber, 
    hobbies, etc...
    FROM USERS
)x

This kind of code perhaps should work for You

SELECT
 *,
 CASE
  WHEN (pvc IS NULL OR pvc = '') AND (datepose < 1980) THEN '01'
  WHEN (pvc IS NULL OR pvc = '') AND (datepose >= 1980) THEN '02'
  WHEN (pvc IS NULL OR pvc = '') AND (datepose IS NULL OR datepose = 0) THEN '03'
  ELSE '00'
 END AS modifiedpvc
FROM my_table;


 gid | datepose | pvc | modifiedpvc 
-----+----------+-----+-------------
   1 |     1961 | 01  | 00
   2 |     1949 |     | 01
   3 |     1990 | 02  | 00
   1 |     1981 |     | 02
   1 |          | 03  | 00
   1 |          |     | 03
(6 rows)

You can also do like this

select *
from table
where columnName like '%' + case when @varColumn is null then '' else @varColumn end  +  ' %'

As of data.table v1.13.0 you can use the function fcase() (fast-case) to do SQL-like CASE operations (also similar to dplyr::case_when()):

require(data.table)

dt <- data.table(name = c('cow','pig','eagle','pigeon','cow','eagle'))
dt[ , category := fcase(name %in% c('cow', 'pig'), 'mammal',
                        name %in% c('eagle', 'pigeon'), 'bird') ]

I think submitHandler with jquery validation is good solution. Please get idea from this code. Inspired from @Darin Dimitrov

$('.calculate').validate({

                submitHandler: function(form) {
                    $.ajax({
                        url: 'response.php',
                        type: 'POST',
                        data: $(form).serialize(),
                        success: function(response) {
                            $('#'+form.id+' .ht-response-data').html(response);
                        }            
                    });
                }
            });

public class GenerateEncryptedPassword {

    public static void main(String[] args){

        Scanner sc= new Scanner(System.in);    
        System.out.println("Please enter the password that needs to be encrypted :");
        String input = sc.next();

        try {
            String encryptedPassword= AESencrp.encrypt(input);
            System.out.println("Encrypted password generated is :"+encryptedPassword);
        } catch (Exception ex) {
            Logger.getLogger(GenerateEncryptedPassword.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
}

.pyc contain the compiled bytecode of Python source files. The Python interpreter loads .pyc files before .py files, so if they're present, it can save some time by not having to re-compile the Python source code. You can get rid of them if you want, but they don't cause problems, they're not big, and they may save some time when running programs.

We use Akka to process REST calls asynchronously - together with async web server (Netty-based) we can achieve 10 fold improvement on the number of users served per node/server, comparing to traditional thread per user request model.

Tell it to your boss that your AWS hosting bill is going to drop by the factor of 10 and it is a no-brainer! Shh... dont tell it to Amazon though... :)

If you are not validating explicitly for numbers in the text field, in any case its better to use

int result=0;
if(int.TryParse(textBox1.Text,out result))

Now if the result is success then you can proceed with your calculations.

One of the uses which I found to be very useful is the print_function from __future__ module.

In Python 2.7, I wanted chars from different print statements to be printed on same line without spaces.

It can be done using a comma(",") at the end, but it also appends an extra space. The above statement when used as :

from __future__ import print_function
...
print (v_num,end="")
...

This will print the value of v_num from each iteration in a single line without spaces.

In order to answer your question, we need two elements:

1. Understanding of the characteristics of different architecture styles/patterns.
2. Understanding of the characteristics of different programming paradigms.

A list of software architecture styles/pattern is shown on the software architecture article on Wikipeida. And you can research on them easily on the web.

In short and general, Procedural is good for a model that follows a procedure, OOP is good for design, and Functional is good for high level programming.

I think you should try reading the history on each paradigm and see why people create it and you can understand them easily.

After understanding them both, you can link the items of architecture styles/patterns to programming paradigms.

Do you have multiple mongodb nodes in a replica set?

I found (I am using via Robomongo gui mongo shell, I guess same applies in other cases) that the correct remove syntax, i.e.

db.test_users.remove({"_id": ObjectId("4d512b45cc9374271b02ec4f")})

...does not work unless you are connected to the primary node of the replica set.

I had 20.8 GB in the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder (6 android images: - android-10 - android-15 - android-21 - android-23 - android-25 - android-26 ).

I have compressed the C:\Users\ggo\AppData\Local\Android\Sdk\system-images folder.

Now it takes only 4.65 GB.

I did not encountered any problem up to now...

Compression seems to vary from 2/3 to 6, sometimes much more:

Without any configuration, you can simply issue the following command (modifying myusername and mydomain with your own information):

cntlm -u myusername -d mydomain -H

or

cntlm -u myusername@mydomain -H

It will ask you the password of myusername and will give you the following output:

PassLM          1AD35398BE6565DDB5C4EF70C0593492
PassNT          77B9081511704EE852F94227CF48A793
PassNTLMv2      A8FC9092D566461E6BEA971931EF1AEC    # Only for user 'myusername', domain 'mydomain'

Then create the file cntlm.ini (or cntlm.conf on Linux using default path) with the following content (replacing your myusername, mydomain and A8FC9092D566461E6BEA971931EF1AEC with your information and the result of the previous command):

Username    myusername
Domain      mydomain

Proxy       my_proxy_server.com:80
NoProxy     127.0.0.*, 192.168.*

Listen      127.0.0.1:5865
Gateway     yes

SOCKS5Proxy 5866

Auth        NTLMv2
PassNTLMv2  A8FC9092D566461E6BEA971931EF1AEC

Then you will have a local open proxy on local port 5865 and another one understanding SOCKS5 protocol at local port 5866.

How about this approach:

• For every client request, the server compares the expirationTime of the token with (currentTime - lastAccessTime)
• If expirationTime < (currentTime - lastAccessedTime), it changes the last lastAccessedTime to currentTime.
• In case of inactivity on the browser for a time duration exceeding expirationTime or in case the browser window was closed and the expirationTime > (currentTime - lastAccessedTime), and then the server can expire the token and ask the user to login again.

We don't require additional end point for refreshing the token in this case. Would appreciate any feedack.

Annotation-driven indicates to Spring that it should scan for annotated beans, and to not just rely on XML bean configuration. Component-scan indicates where to look for those beans.

Here's some doc: http://static.springsource.org/spring/docs/current/spring-framework-reference/html/mvc.html#mvc-config-enable

FOR EXAMPLE YOU HAVE RECIEVED JASON DATA FROM SERVER.

                var obj = JSON.parse(msg);
                var tableString ="<table id='tbla'>";
                tableString +="<th><td>Name<td>City<td>Birthday</th>";


                for (var i=0; i<obj.length; i++){
                    //alert(obj[i].name);
                    tableString +=gg_stringformat("<tr><td>{0}<td>{1}<td>{2}</tr>",obj[i].name, obj[i].age, obj[i].birthday);
                }
                tableString +="</table>";
                alert(tableString);
                $('#divb').html(tableString);

HERE IS THE CODE FOR gg_stringformat

function gg_stringformat() {
var argcount = arguments.length,
    string,
    i;

if (!argcount) {
    return "";
}
if (argcount === 1) {
    return arguments[0];
}
string = arguments[0];
for (i = 1; i < argcount; i++) {
    string = string.replace(new RegExp('\\{' + (i - 1) + '}', 'gi'), arguments[i]);
}
return string;

}

To just get the size of the directory, nothing more:

du --max-depth=0 ./directory

output looks like

5234232       ./directory

Use the command-line option -O0 (-[capital o][zero]) to disable optimization, and -S to get assembly file. Look here to see more gcc command-line options.

Your file has Windows line endings, which is confusing Linux.

Remove the spurious CR characters. You can do it with the following command:

Posting and answer because there is a lot of outdated ideas and confusion about the standards. As of December 2017, there are two competing standards:

RFC 8259 - https://tools.ietf.org/html/rfc8259

ECMA-404 - http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-404.pdf

json.org suggests ECMA-404 is the standard, but this site does not appear to be an authority. While I think it's fair to consider ECMA the authority, what's important here is, the only difference between the standards (regarding unique keys) is that RFC 8259 says the keys should be unique, and the ECMA-404 says they are not required to be unique.

RFC-8259:

"The names within an object SHOULD be unique."

The word "should" in all caps like that, has a meaning within the RFC world, that is specifically defined in another standard (BCP 14, RFC 2119 - https://tools.ietf.org/html/rfc2119) as,

3. SHOULD This word, or the adjective "RECOMMENDED", mean that there may exist valid reasons in particular circumstances to ignore a particular item, but the full implications must be understood and carefully weighed before choosing a different course.

ECMA-404:

"The JSON syntax does not impose any restrictions on the strings used as names, does not require that name strings be unique, and does not assign any significance to the ordering of name/value pairs."

So, no matter how you slice it, it's syntactically valid JSON.

The reason given for the unique key recommendation in RFC 8259 is,

An object whose names are all unique is interoperable in the sense that all software implementations receiving that object will agree on the name-value mappings. When the names within an object are not unique, the behavior of software that receives such an object is unpredictable. Many implementations report the last name/value pair only. Other implementations report an error or fail to parse the object, and some implementations report all of the name/value pairs, including duplicates.

In other words, from the RFC 8259 viewpoint, it's valid but your parser may barf and there's no promise as to which, if any, value will be paired with that key. From the ECMA-404 viewpoint (which I'd personally take as the authority), it's valid, period. To me this means that any parser that refuses to parse it is broken. It should at least parse according to both of these standards. But how it gets turned into your native object of choice is, in any case, unique keys or not, completely dependent on the environment and the situation, and none of that is in the standard to begin with.

AFAIK, fragments cannot hold other fragments.

UPDATE

With current versions of the Android Support package -- or native fragments on API Level 17 and higher -- you can nest fragments, by means of getChildFragmentManager(). Note that this means that you need to use the Android Support package version of fragments on API Levels 11-16, because even though there is a native version of fragments on those devices, that version does not have getChildFragmentManager().

Just use CR to go to beginning of the line.

import time
for x in range (0,5):  
    b = "Loading" + "." * x
    print (b, end="\r")
    time.sleep(1)

I am a maintainer of react-native-spannable-string

Nested <Text/> component with custom style works well but maintainability is low.

I suggest you build spannable string like this with this library.

SpannableBuilder.getInstance({ fontSize: 24 })
    .append('Using ')
    .appendItalic('Italic')
    .append(' in Text')
    .build()

Actually you don't even need the block:

  Dir.chdir 'C:/Users/name/Music'
  music = Dir['C:/Users/name/Music/*.{mp3, MP3}']
  puts 'what would you like to call the playlist?'
  playlist_name = gets.chomp + '.m3u'

  File.open(playlist_name, 'w').puts(music)

The only database I know that does this is SQLite, depending on the settings you configure with PRAGMA full_column_names and PRAGMA short_column_names. See http://www.sqlite.org/pragma.html

Otherwise all I can recommend is to fetch columns in a result set by ordinal position rather than by column name, if it's too much trouble for you to type the names of the columns in your query.

This is a good example of why it's bad practice to use SELECT * -- because eventually you'll have a need to type out all the column names anyway.

I understand the need to support columns that may change name or position, but using wildcards makes that harder, not easier.

You should read up on the onclick html attribute and the window.open() documentation. Below is what you want.

<a href='#' onclick='window.open("http://www.google.com", "myWin", "scrollbars=yes,width=400,height=650"); return false;'>1</a>

JSFiddle: http://jsfiddle.net/TBcVN/

 Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT);

makes the toast, but doesnt show it.

You have to do Toast.makeText(getApplicationContext(), "received", Toast.LENGTH_SHORT).show();

You should use something like this:

<div style="text-align:center">  
    <input type="submit" />  
</div>  

Or you could use something like this. By giving the element a width and specifying auto for the left and right margins the element will center itself in its parent.

<input type="submit" style="width: 300px; margin: 0 auto;" />

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

Concatenate " as a ceparate cell:

    A |   B   | C | D
1   " | text  | " | =CONCATENATE(A1; B1; C1);

D1 displays "text"

While writing to S3, you need to specify the length of S3 object to be sure that there are no out of memory errors.

Using IOUtils.toByteArray(stream) is also prone to OOM errors because this is backed by ByteArrayOutputStream

So, the best option is to first write the inputstream to a temp file on local disk and then use that file to write to S3 by specifying the length of temp file.

use this syntax: alter table table_name modify column col_name varchar (10000);

If it's a Maven project:

1. Go to the POM file.
2. Remove all the dependencies.
3. Save the POM file.
4. Again import only the necessary dependencies.
5. Save the POM file.

The issue should go away.

You can simply place a forward declaration of your second() function in your main.cpp above main(). If your second.cpp has more than one function and you want all of it in main(), put all the forward declarations of your functions in second.cpp into a header file and #include it in main.cpp.

Like this-

Second.h:

void second();
int third();
double fourth();

main.cpp:

#include <iostream>
#include "second.h"
int main()
{
    //.....
    return 0;
}

second.cpp:

void second()
{
    //...
}

int third()
{ 
    //...
    return foo;
}

double fourth()
{ 
    //...
    return f;
}

Note that: it is not necessary to #include "second.h" in second.cpp. All your compiler need is forward declarations and your linker will do the job of searching the definitions of those declarations in the other files.

I prefer the simplicity and flexibility of the 12 factor app recommendation for logging. To append to a log file you can use shell redirection. The default logger in Go writes to stderr (2).

./app 2>> logfile

In order for sudo to work the way everyone suggest, you need to be in the admin group.

In order to run the bootstrap date time picker you need to include Moment.js as well. Here is the working code sample in your case.

Using old C++ version, you can use this snippet :

template<typename T>
string toBinary(const T& t)
{
  string s = "";
  int n = sizeof(T)*8;
  for(int i=n-1; i>=0; i--)
  {
    s += (t & (1 << i))?"1":"0";
  }
  return s;
}

int main()
{
  char a, b;

  short c;
  a = -58;
  c = -315;

  b = a >> 3;

  cout << "a = " << a << " => " << toBinary(a) << endl;
  cout << "b = " << b << " => " << toBinary(b) << endl;
  cout << "c = " << c << " => " << toBinary(c) << endl;
}

a = => 11000110
b = => 11111000
c = -315 => 1111111011000101

Use the Below Code for that

UPDATE Table1 SET Column1 = LTRIM(RTRIM(REPLACE(REPLACE(REPLACE(Column1, CHAR(9), ''), CHAR(10), ''), CHAR(13), '')))`

It's a great idea to use cURL as suggested by rojoca.

Here is an example. You can monitor text.txt while the script is running in background:

<?php

function doCurl($begin)
{
    echo "Do curl<br />\n";
    $url = 'http://'.$_SERVER['SERVER_NAME'].$_SERVER['REQUEST_URI'];
    $url = preg_replace('/\?.*/', '', $url);
    $url .= '?begin='.$begin;
    echo 'URL: '.$url.'<br>';
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $result = curl_exec($ch);
    echo 'Result: '.$result.'<br>';
    curl_close($ch);
}


if (empty($_GET['begin'])) {
    doCurl(1);
}
else {
    while (ob_get_level())
        ob_end_clean();
    header('Connection: close');
    ignore_user_abort();
    ob_start();
    echo 'Connection Closed';
    $size = ob_get_length();
    header("Content-Length: $size");
    ob_end_flush();
    flush();

    $begin = $_GET['begin'];
    $fp = fopen("text.txt", "w");
    fprintf($fp, "begin: %d\n", $begin);
    for ($i = 0; $i < 15; $i++) {
        sleep(1);
        fprintf($fp, "i: %d\n", $i);
    }
    fclose($fp);
    if ($begin < 10)
        doCurl($begin + 1);
}

?>

We have experienced an issue today where a UTF8 character in an author name was causing trouble on the build server, so we had to rewrite the history to correct this. The steps taken were:

Step 1: Change your username in git for all future commits, as per instructions here: https://help.github.com/articles/setting-your-username-in-git/

Step 2: Run the following bash script:

#!/bin/sh

REPO_URL=ssh://path/to/your.git
REPO_DIR=rewrite.tmp

# Clone the repository
git clone ${REPO_URL} ${REPO_DIR}

# Change to the cloned repository
cd ${REPO_DIR}

# Checkout all the remote branches as local tracking branches
git branch --list -r origin/* | cut -c10- | xargs -n1 git checkout

# Rewrite the history, use a system that will preseve the eol (or lack of in commit messages) - preferably Linux not OSX
git filter-branch --env-filter '
OLD_EMAIL="[email protected]"
CORRECT_NAME="New Me"

if [ "$GIT_COMMITTER_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_COMMITTER_NAME="$CORRECT_NAME"
fi
if [ "$GIT_AUTHOR_EMAIL" = "$OLD_EMAIL" ]
then
    export GIT_AUTHOR_NAME="$CORRECT_NAME"
fi
' --tag-name-filter cat -- --branches --tags

# Force push the rewritten branches + tags to the remote
git push -f

# Remove all knowledge that we did something
rm -rf ${REPO_DIR}

# Tell your colleagues to `git pull --rebase` on all their local remote tracking branches

Quick overview: Checkout your repository to a temp file, checkout all the remote branches, run the script which will rewrite the history, do a force push of the new state, and tell all your colleagues to do a rebase pull to get the changes.

We had trouble with running this on OS X because it somehow messed up line endings in commit messages, so we had to re-run it on a Linux machine afterwards.

You might consider this for guidelines on when to go for struct or class, https://msdn.microsoft.com/en-us/library/ms229017%28v=vs.110%29.aspx .

v CONSIDER defining a struct instead of a class if instances of the type are small and commonly short-lived or are commonly embedded in other objects.

X AVOID defining a struct unless the type has all of the following characteristics:

It logically represents a single value, similar to primitive types (int, double, etc.).

It has an instance size under 16 bytes.

It is immutable.

It will not have to be boxed frequently.

I had some trouble with this - my EntityKey consists of three properties (PK with 3 columns) and I didn't want to check each of the columns because that would be ugly. I thought about a solution that works all time with all entities.

Another reason for this is I don't like to catch UpdateExceptions every time.

A little bit of Reflection is needed to get the values of the key properties.

The code is implemented as an extension to simplify the usage as:

context.EntityExists<MyEntityType>(item);

Have a look:

public static bool EntityExists<T>(this ObjectContext context, T entity)
        where T : EntityObject
    {
        object value;
        var entityKeyValues = new List<KeyValuePair<string, object>>();
        var objectSet = context.CreateObjectSet<T>().EntitySet;
        foreach (var member in objectSet.ElementType.KeyMembers)
        {
            var info = entity.GetType().GetProperty(member.Name);
            var tempValue = info.GetValue(entity, null);
            var pair = new KeyValuePair<string, object>(member.Name, tempValue);
            entityKeyValues.Add(pair);
        }
        var key = new EntityKey(objectSet.EntityContainer.Name + "." + objectSet.Name, entityKeyValues);
        if (context.TryGetObjectByKey(key, out value))
        {
            return value != null;
        }
        return false;
    }

Stub is a function definition that has correct function name, the correct number of parameters and produces dummy result of the correct type.

It helps to write the test and serves as a kind of scaffolding to make it possible to run the examples even before the function design is complete

The Pumping lemma for regular languages is the reason why you can't do that.

The generated automaton will have a finite number of states, say k, so a string of k+1 opening braces is bound to have a state repeated somewhere (as the automaton processes the characters). The part of the string between the same state can be duplicated infinitely many times and the automaton will not know the difference.

In particular, if it accepts k+1 opening braces followed by k+1 closing braces (which it should) it will also accept the pumped number of opening braces followed by unchanged k+1 closing brases (which it shouldn't).

Every InvoiceItem must have an Invoice attached to it because of the not-null="true" in the many-to-one mapping.

So the basic idea is you need to set up that explicit relationship in code. There are many ways to do that. On your class I see a setItems method. I do NOT see an addInvoiceItem method. When you set items, you need to loop through the set and call item.setInvoice(this) on all of the items. If you implement an addItem method, you need to do the same thing. Or you need to otherwise set the Invoice of every InvoiceItem in the collection.

Alternative way:

std::string s = "This is an STL string";
QString qs = QString::fromAscii(s.data(), s.size());

This has the advantage of not using .c_str() which might cause the std::string to copy itself in case there is no place to add the '\0' at the end.

The details at http://net.tutsplus.com/tutorials/tools-and-tips/how-to-work-with-github-and-multiple-accounts/ linked to by mishaba work very well for me.

From that page:

$ touch ~/.ssh/config

Then edit that file to be something like this (one entry per account):

#Default GitHub

  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa

Host github-COMPANY
  HostName github.com
  User git
  IdentityFile ~/.ssh/id_rsa_COMPANY

rand() will return numbers between 0 and RAND_MAX, which is at least 32767.

If you want to get a number within a range, you can just use modulo.

int value = rand() % 66; // 0-65

For more accuracy, check out this article. It discusses why modulo is not necessarily good (bad distributions, particularly on the high end), and provides various options.

You have to create one Context Class.

public class Context {
    private final static Context instance = new Context();
    public static Context getInstance() {
        return instance;
    }

    private Connection con;
    public void setConnection(Connection con)
    {
        this.con=con;
    }
    public Connection getConnection() {
        return con;
    }

    private TabRoughController tabRough;
    public void setTabRough(TabRoughController tabRough) {
        this.tabRough=tabRough;
    }

    public TabRoughController getTabRough() {
        return tabRough;
    }
}

You have to just set instance of controller in initialization using

Context.getInstance().setTabRough(this);

and you can use it from your whole application just using

TabRoughController cont=Context.getInstance().getTabRough();

Now you can pass parameter to any controller from whole application.

Use .push:

items.push({'id':5});

Another workaround for those who don't need the entire shebang: use the switch

-DBOOST_ERROR_CODE_HEADER_ONLY.

If you use CMake, it's add_definitions(-DBOOST_ERROR_CODE_HEADER_ONLY).

Update: ASP.NET Core does not have a SynchronizationContext. If you are on ASP.NET Core, it does not matter whether you use ConfigureAwait(false) or not.

For ASP.NET "Full" or "Classic" or whatever, the rest of this answer still applies.

Original post (for non-Core ASP.NET):

This video by the ASP.NET team has the best information on using async on ASP.NET.

I had read that it is more performant since it doesn't have to switch thread contexts back to the original thread context.

This is true with UI applications, where there is only one UI thread that you have to "sync" back to.

In ASP.NET, the situation is a bit more complex. When an async method resumes execution, it grabs a thread from the ASP.NET thread pool. If you disable the context capture using ConfigureAwait(false), then the thread just continues executing the method directly. If you do not disable the context capture, then the thread will re-enter the request context and then continue to execute the method.

So ConfigureAwait(false) does not save you a thread jump in ASP.NET; it does save you the re-entering of the request context, but this is normally very fast. ConfigureAwait(false) could be useful if you're trying to do a small amount of parallel processing of a request, but really TPL is a better fit for most of those scenarios.

However, with ASP.NET Web Api, if your request is coming in on one thread, and you await some function and call ConfigureAwait(false) that could potentially put you on a different thread when you are returning the final result of your ApiController function.

Actually, just doing an await can do that. Once your async method hits an await, the method is blocked but the thread returns to the thread pool. When the method is ready to continue, any thread is snatched from the thread pool and used to resume the method.

The only difference ConfigureAwait makes in ASP.NET is whether that thread enters the request context when resuming the method.

I have more background information in my MSDN article on SynchronizationContext and my async intro blog post.

You can use this regex to get the yyyy-MM-dd format:

((?:19|20)\\d\\d)-(0?[1-9]|1[012])-([12][0-9]|3[01]|0?[1-9])

You can find example for date validation: How to validate date with regular expression.

I was unable to resolve my problem with any of the other answers. I resolved the issue by checking to see if the host matched and returning a 403 if it did not. (I had some random website pointing to my web servers content. I'm guessing to hijack search rank)

server {
    listen 443;
    server_name example.com;

    if ($host != "example.com") {
        return 403;
    }

    ...
}

try:

Cursor  cursor = db.rawQuery("select * from table",null);

AND for List<String>:

if (cursor.moveToFirst()) {
  while (!cursor.isAfterLast()) {
    String name = cursor.getString(cursor.getColumnIndex(countyname));

    list.add(name);
    cursor.moveToNext();
  }
}

Another option would be to add engine='python' to the command pandas.read_csv(filename, sep='\t', engine='python')

Are these structures padded or packed?

They're padded.

The only possibility that initially springs to mind, where they could be packed, is if char and int were the same size, so that the minimum size of the char/int/char structure would allow for no padding, ditto for the int/char structure.

However, that would require both sizeof(int) and sizeof(char) to be four (to get the twelve and eight sizes). The whole theory falls apart since it's guaranteed by the standard that sizeof(char) is always one.

Were char and int the same width, the sizes would be one and one, not four and four. So, in order to then get a size of twelve, there would have to be padding after the final field.

When does padding or packing take place?

Whenever the compiler implementation wants it to. Compilers are free to insert padding between fields, and following the final field (but not before the first field).

This is usually done for performance as some types perform better when they're aligned on specific boundaries. There are even some architectures that will refuse to function (i.e, crash) is you try to access unaligned data (yes, I'm looking at you, ARM).

You can generally control packing/padding (which is really opposite ends of the same spectrum) with implementation-specific features such as #pragma pack. Even if you cannot do that in your specific implementation, you can check your code at compile time to ensure it meets your requirement (using standard C features, not implementation-specific stuff).

For example:

// C11 or better ...
#include <assert.h>
struct strA { char a; int  b; char c; } x;
struct strB { int  b; char a;         } y;
static_assert(sizeof(struct strA) == sizeof(char)*2 + sizeof(int), "No padding allowed");
static_assert(sizeof(struct strB) == sizeof(char)   + sizeof(int), "No padding allowed");

Something like this will refuse to compile if there is any padding in those structures.

Use make (chan int) instead of nil. The first value has to be the same type that your map holds.

package main

import "fmt"

func main() {

    var sessions = map[string] chan int{}
    sessions["somekey"] = make(chan int)

    fmt.Printf ("%d\n", len(sessions)) // 1

    // Remove somekey's value from sessions
    delete(sessions, "somekey")

    fmt.Printf ("%d\n", len(sessions)) // 0
}

UPDATE: Corrected my answer.

Thanks to all the investigations of Lance, I could find a solution to my problem. It possibly had to do with my ISP.

To summarize:

• Internet sites were displayed in the Intranet zone
• Because of that the document mode was defaulted to 5 or 7 instead of Edge

I unchecked the "Automatically detect settings" in the Local Area Network Settings (found in "Internet Options" > Connections > LAN Settings.

Now the sites are correctly marked as Internet sites (instead of Intranet sites).

I'm not sure exactly what you want, but it sounds like it should be possible, and it also sounds like you're already on the right track.

Here are a few links that might help:

Disable back button in android

Had a similar problem. My solution was to give the inner table a fixed height of 1px and set the height of the td in the inner table to 100%. Against all odds, it works fine, tested in IE, Chrome and FF!

Static data members declarations in the class declaration are not definition of them. To define them you should do this in the .CPP file to avoid duplicated symbols.

The only data you can declare and define is integral static constants. (Values of enums can be used as constant values as well)

You might want to rewrite your code as:

class test {
public:
  const static unsigned char X = 1;
  const static unsigned char Y = 2;
  ...
  test();
};

test::test() {
}

If you want to have ability to modify you static variables (in other words when it is inappropriate to declare them as const), you can separate you code between .H and .CPP in the following way:

.H :

class test {
public:

  static unsigned char X;
  static unsigned char Y;

  ...

  test();
};

.CPP :

unsigned char test::X = 1;
unsigned char test::Y = 2;

test::test()
{
  // constructor is empty.
  // We don't initialize static data member here, 
  // because static data initialization will happen on every constructor call.
}

public DataTable TopDataRow(DataTable dt, int count)
    {
        DataTable dtn = dt.Clone();
        int i = 0;
        foreach (DataRow row in dt.Rows)
        {
            if (i < count)
            {
                dtn.ImportRow(row);
                i++;
            }
            if (i > count)
                break;
        }
        return dtn;
    }

Just open your repository file and add this new function, then call it inside your controller:

 public function distinctCategories(){
        return $this->createQueryBuilder('cc')
        ->where('cc.contenttype = :type')
        ->setParameter('type', 'blogarticle')
        ->groupBy('cc.blogarticle')
        ->getQuery()
        ->getResult()
        ;
    }

Then within your controller:

public function index(YourRepository $repo)
{
    $distinctCategories = $repo->distinctCategories();


    return $this->render('your_twig_file.html.twig', [
        'distinctCategories' => $distinctCategories
    ]);
}

Good luck!

I found the better solution. This can be achieved through RegEx:

if (str.matches("val1|val2|val3")) {
     // remaining code
}

For case insensitive matching:

if (str.matches("(?i)val1|val2|val3")) {
     // remaining code
}

Place this css in your page:

<style>
   #client_logos {
    display: inline-block;
    width:100%;
    }
  </style>

Replace

<p><img class="alignnone" style="display: inline; margin: 0 10px;" title="heartica_logo" src="https://s3.amazonaws.com/rainleader/assets/heartica_logo.png" alt="" width="150" height="50" /><img class="alignnone" style="display: inline; margin: 0 10px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/mouseflow_logo.png" alt="" width="150" height="50" /><img class="alignnone" style="display: inline; margin: 0 10px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/piiholo_logo.png" alt="" width="150" height="50" /></p>

To

<div id="client_logos">
<img style="display: inline; margin: 0 5px;" title="heartica_logo" src="https://s3.amazonaws.com/rainleader/assets/heartica_logo.png" alt="" width="150" height="50" />
<img style="display: inline; margin: 0 5px;" title="mouseflow_logo" src="https://s3.amazonaws.com/rainleader/assets/mouseflow_logo.png" alt="" width="150" height="50" />
<img style="display: inline; margin: 0 5px;" title="piiholo_logo" src="https://s3.amazonaws.com/rainleader/assets/piiholo_logo.png" alt="" width="150" height="50" />
</div>

Use System.DateTime.DaysInMonth, from code sample:

const int July = 7;
const int Feb = 2;

// daysInJuly gets 31.
int daysInJuly = System.DateTime.DaysInMonth(2001, July);

// daysInFeb gets 28 because the year 1998 was not a leap year.
int daysInFeb = System.DateTime.DaysInMonth(1998, Feb);

// daysInFebLeap gets 29 because the year 1996 was a leap year.
int daysInFebLeap = System.DateTime.DaysInMonth(1996, Feb);

Modern browsers will take script tags in the body like so:

<body>
    <script src="scripts/main.js"></script>
</body>

Basically, it means that the script will be loaded once the page has finished, which may be useful in certain cases (namely DOM manipulation). However, I highly recommend you take the same script and put it in the head tag with "defer", as it will give the same effect.

<head>
    <script src="scripts/main.js" defer></script>
</head>

You can use the $$ variable.

My solution is put those imports in __init__.py of lib:

in file: __init__.py
import mod1

Then,

import lib
lib.mod1

would work fine.

$ne

selects the documents where the value of the field is not equal to the specified value. This includes documents that do not contain the field.

User.find({ "username": { "$ne": 'admin' } })

$nin

$nin selects the documents where: the field value is not in the specified array or the field does not exist.

User.find({ "groups": { "$nin": ['admin', 'user'] } })

There is also a POSIX library for POSIX operating systems. Check for compatability

#include <stdio.h>
#include <stdlib.h>
#include <pthread.h>
#include <iostream>

void *task(void *argument){
      char* msg;
      msg = (char*)argument;
      std::cout<<msg<<std::endl;
}

int main(){
    pthread_t thread1, thread2;
    int i1,i2;
    i1 = pthread_create( &thread1, NULL, task, (void*) "thread 1");
    i2 = pthread_create( &thread2, NULL, task, (void*) "thread 2");

    pthread_join(thread1,NULL);
    pthread_join(thread2,NULL);
    return 0;

}

compile with -lpthread

AppCompat doesn't do that for dialogs (not yet at least)

EDIT: it does now. make sure to use android.support.v7.app.AlertDialog

Including this answer because this was the top result for "invalid column name sql" on google and I didn't see this answer here. In my case, I was getting Invalid Column Name, Id1 because I had used the wrong id in my .HasForeignKey statement in my Entity Framework C# code. Once I changed it to match the .HasOne() object's id, the error was gone.

I think move would probably be the closest standard cursor value for what you're doing:

move
Indicates something is to be moved.

SQL Server requires subqueries that you SELECT FROM or JOIN to have an alias.

Add an alias to your subquery (in this case x):

select COUNT(*) from
(
select m.Company_id
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5)  x

I know i am VERY late to the party but i want to put it out here so that it is listed.

As well as all of the above advice for making sure that fields are identically defined, and table types also have the same collation, make sure that you don't make the rookie mistake of trying to link fields where data in the CHILD field is not already in the PARENT field. If you have data that is in the CHILD field that you have not already entered in to the PARENT field then that will cause this error. It's a shame that the error message is not a bit more helpful.

If you are unsure, then backup the table that has the Foreign Key, delete all the data and then try to create the Foreign Key. If successful then you what to do!

Good luck.

COPY copies a file/directory from your host to your image.

ADD copies a file/directory from your host to your image, but can also fetch remote URLs, extract TAR files, etc...

Use COPY for simply copying files and/or directories into the build context.

Use ADD for downloading remote resources, extracting TAR files, etc..

Detecting and Correcting the ObjectID Error

I stumbled into this problem when trying to delete an item using mongoose and got the same error. After looking over the return string, I found there were some extra spaces inside the returned string which caused the error for me. So, I applied a few of the answers provided here to detect the erroneous id then remove the extra spaces from the string. Here is the code that worked for me to finally resolve the issue.

const mongoose = require("mongoose");
mongoose.set('useFindAndModify', false);  //was set due to DeprecationWarning: Mongoose: `findOneAndUpdate()` and `findOneAndDelete()` without the `useFindAndModify`



app.post("/delete", function(req, res){
  let checkedItem = req.body.deleteItem;
  if (!mongoose.Types.ObjectId.isValid(checkedItem)) {
    checkedItem = checkedItem.replace(/\s/g, '');
  }

  Item.findByIdAndRemove(checkedItem, function(err) {
    if (!err) {
      console.log("Successfully Deleted " + checkedItem);
        res.redirect("/");
      }
    });
});

This worked for me and I assume if other items start to appear in the return string they can be removed in a similar way.

I hope this helps.

@andyb's accepted answer has a small bug. Further to my comment on his post above...

For this HTML:

<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>

You need to access the attribute like this:

$('#foo').attr('data-helptext', 'Testing 123');

but the data method like this:

$('#foo').data('helptext', 'Testing 123');

The fix above for the .data() method will prevent "undefined" and the data value will be updated (while the HTML will not)

The point of the "data" attribute is to bind (or "link") a value with the element. Very similar to the onclick="alert('do_something')" attribute, which binds an action to the element... the text is useless you just want the action to work when they click the element.

Once the data or action is bound to the element, there is usually* no need to update the HTML, only the data or method, since that is what your application (JavaScript) would use. Performance wise, I don't see why you would want to also update the HTML anyway, no one sees the html attribute (except in Firebug or other consoles).

One way you might want to think about it: The HTML (along with attributes) are just text. The data, functions, objects, etc that are used by JavaScript exist on a separate plane. Only when JavaScript is instructed to do so, it will read or update the HTML text, but all the data and functionality you create with JavaScript are acting completely separate from the HTML text/attributes you see in your Firebug (or other) console.

*I put emphasis on usually because if you have a case where you need to preserve and export HTML (e.g. some kind of micro format/data aware text editor) where the HTML will load fresh on another page, then maybe you need the HTML updated too.

How PHP handles sessions is quite confusing for beginners to understand. This might help them by giving an overview of how sessions work: how sessions work(custom-session-handlers)

You don't have to use atan2 to calculate the angle between two vectors. If you just want the quickest way, you can use dot(v1, v2)=|v1|*|v2|*cos A to get

A = Math.acos( dot(v1, v2)/(v1.length()*v2.length()) );

This is working Oracle example but it should work in MySQL too.

You are missing smth - see IN after END Replace 'IN' with '=' sign for a single value.

SELECT empno, ename, job
  FROM scott.emp
 WHERE (CASE WHEN job = 'MANAGER' THEN '1'  
         WHEN job = 'CLERK'   THEN '2' 
         ELSE '0'  END) IN (1, 2)

Location of log file can be control through logging.properties file. And it can be passed as JVM parameter ex : java -Djava.util.logging.config.file=/scratch/user/config/logging.properties

Details: https://docs.oracle.com/cd/E23549_01/doc.1111/e14568/handler.htm

Configuring the File handler

To send logs to a file, add FileHandler to the handlers property in the logging.properties file. This will enable file logging globally.

handlers= java.util.logging.FileHandler Configure the handler by setting the following properties:

java.util.logging.FileHandler.pattern=<home directory>/logs/oaam.log
java.util.logging.FileHandler.limit=50000
java.util.logging.FileHandler.count=1
java.util.logging.FileHandler.formatter=java.util.logging.SimpleFormatter

java.util.logging.FileHandler.pattern specifies the location and pattern of the output file. The default setting is your home directory.

java.util.logging.FileHandler.limit specifies, in bytes, the maximum amount that the logger writes to any one file.

java.util.logging.FileHandler.count specifies how many output files to cycle through.

java.util.logging.FileHandler.formatter specifies the java.util.logging formatter class that the file handler class uses to format the log messages. SimpleFormatter writes brief "human-readable" summaries of log records.

To instruct java to use this configuration file instead of $JDK_HOME/jre/lib/logging.properties:

java -Djava.util.logging.config.file=/scratch/user/config/logging.properties

I implemented access using the following

class D(Enum):
    x = 1
    y = 2

    def __str__(self):
        return '%s' % self.value

now I can just do

print(D.x) to get 1 as result.

You can also use self.name in case you wanted to print x instead of 1.

I had faced similar issue on IE10. I had a workaround by using the jQuery ajax request to retrieve data:

$.ajax({
    url: YOUR_XML_FILE
    aync: false,
    success: function (data) {   
        // Store data into a variable
    },
    dataType: YOUR_DATA_TYPE,
    complete: ON_COMPLETE_FUNCTION_CALL
});

Here's an alternative way to do the same call. And your type should always be in CAPS, eg. type:"GET" / type:"POST".

$.ajax({
      url:/ControllerName/ActionName,
      data: "id=" + Id + "&param2=" + param2,
      type: "GET",
      success: function(data){
            // code here
      },
      error: function(passParams){
           // code here
      }
});

Another alternative will be to use the data-ajax on a link.

<a href="/ControllerName/ActionName/" data-ajax="true" data-ajax-method="GET" data-ajax-mode="replace" data-ajax-update="#_content">Click Me!</a>

Assuming u had a div with the I'd _content, this will call the action and replace the content inside that div with the data returned from that action.

<div id="_content"></div>

Not really a direct answer to ur question but its some info u should be aware of ;).

import matplotlib.pyplot as plt
def maximize():
    plot_backend = plt.get_backend()
    mng = plt.get_current_fig_manager()
    if plot_backend == 'TkAgg':
        mng.resize(*mng.window.maxsize())
    elif plot_backend == 'wxAgg':
        mng.frame.Maximize(True)
    elif plot_backend == 'Qt4Agg':
        mng.window.showMaximized()

Then call function maximize() before plt.show()

For Mul, this was also helpful documentation to me - http://grokbase.com/t/mysql/mysql/9987k2ew41/key-field-mul-newbie-question

"MUL means that the key allows multiple rows to have the same value. That is, it's not a UNIque key."

For example, let's say you have two models, Post and Comment. Post has a has_many relationship with Comment. It would make sense then for the Comment table to have a MUL key(Post id) because many comments can be attributed to the same Post.

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

If you'd like to do this in ggplot, an API change was made to geom_histogram() that leads to an error: https://github.com/hadley/ggplot2/issues/1465

no problem doing it with asp.... it's most natural to do so with MVC, but can be done with standard asp as well.

The MVC framework has all sorts of helper classes for JSON, if you can, I'd suggest sussing in some MVC-love, if not, you can probably easily just get the JSON helper classes used by MVC in and use them in the context of asp.net.

edit:

here's an example of how to return JSON data with MVC. This would be in your controller class. This is out of the box functionality with MVC--when you crate a new MVC project this stuff gets auto-created so it's nothing special. The only thing that I"m doing is returning an actionResult that is JSON. The JSON method I'm calling is a method on the Controller class. This is all very basic, default MVC stuff:

public ActionResult GetData()
{
    var data = new { Name="kevin", Age=40 };
    return Json(data, JsonRequestBehavior.AllowGet);
}

This return data could be called via JQuery as an ajax call thusly:

$.get("/Reader/GetData/", function(data) { someJavacriptMethodOnData(data); });

Import the spring util namespace. Then you can define a list bean as follows:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:util="http://www.springframework.org/schema/util"
xsi:schemaLocation="http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                    http://www.springframework.org/schema/util
                    http://www.springframework.org/schema/util/spring-util-2.5.xsd">


<util:list id="myList" value-type="java.lang.String">
    <value>foo</value>
    <value>bar</value>
</util:list>

The value-type is the generics type to be used, and is optional. You can also specify the list implementation class using the attribute list-class.

Below mentioned link gives the clear explanation with example.

The accepted answer of this post will cause error in the case when the string length is lest than 5. So i have a better solution. We can use this simple code :

If(str.Length <= 5, str, str.Substring(str.Length - 5))

You can test it with variable length string.

    Dim str, result As String
    str = "11!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)
    str = "I will be going to school in 2011!"
    result = If(str.Length <= 5, str, str.Substring(str.Length - 5))
    MessageBox.Show(result)

Another simple but efficient solution i found :

str.Substring(str.Length - Math.Min(5, str.Length))

Example command for converting each .js file under the current dir to tabs (only leading spaces are converted):

find . -name "*.js" -exec bash -c 'unexpand -t 4 --first-only "$0" > /tmp/totabbuff && mv /tmp/totabbuff "$0"' {} \;

I'm a bit late to the party, but here's a bit of jQuery I've been using:

$('.carousel').on('touchstart', function(event){
    const xClick = event.originalEvent.touches[0].pageX;
    $(this).one('touchmove', function(event){
        const xMove = event.originalEvent.touches[0].pageX;
        const sensitivityInPx = 5;

        if( Math.floor(xClick - xMove) > sensitivityInPx ){
            $(this).carousel('next');
        }
        else if( Math.floor(xClick - xMove) < -sensitivityInPx ){
            $(this).carousel('prev');
        }
    });
    $(this).on('touchend', function(){
        $(this).off('touchmove');
    });
});

No need for jQuery mobile or any other plugins. If you need to adjust the sensitivity of the swipe adjust the 5 and -5. Hope this helps someone.

Using a single sed

echo "/var/cpanel/users/joebloggs:DNS9=domain.com" | sed 's/.*\/\(.*\):.*/\1/'

After several attempts and going deep in Tomcat's source code I found out that the simple property useNaming="false" did the trick!! Now Tomcat resolves names java:/liferay instead of java:comp/env/liferay

As documented in ?legend you do this like so:

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

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

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

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

See also: Convert Java to EXE: Why, When, When Not and How

One option is:

Object.keys(myObject).length

Sadly it not works under older IE versions (under 9).

If you need that compatibility, use the painful version:

var key, count = 0;
for(key in myObject) {
  if(myObject.hasOwnProperty(key)) {
    count++;
  }
}

Try this:

public ActionResult CreatePerson(int id) //controller 

window.location.href = "@Url.Action("CreatePerson", "Person")?Id='+Id+'";

it's working fine passing parameter.

The relative pathing is based on the document level of the client side i.e. the URL level of the document as seen in the browser.

If the URL of your website is: http://www.example.com/mywebsite/ then starting at the root level starts above the "mywebsite" folder path.

[object Object] This means somewhere the object is being converted to a string.

Converted to a string:

//Copy and paste in the browser console to see result

var product = {'name':'test'};
JSON.stringify(product + ''); 

Not converted to a string:

//Copy and paste in the browser console to see result

var product = {'name':'test'};
JSON.stringify(product);

What you need is the function strftime:

Time.now.strftime("%Y-%d-%m %H:%M:%S %Z")

If I understand your question correctly, you need %p to show the address that a pointer is using, for example:

int main() {
    int a = 5;
    int *p = &a;
    printf("%d, %u, %p", p, p, p);

    return 0;
}

will output something like:

-1083791044, 3211176252, 0xbf66a93c

Well I'm not sure about the regex or your situation..

How about CTRL+A, Select the TextFX menu -> TextFX Edit -> Delete Blank Lines and viola all blank line gone.

A side note - if the line is blank i.e. does not contain spaces, this will work

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

The following code snippet is doing it for me (lat and lng are doubles declared above this bit):

Geocoder geocoder = new Geocoder(this, Locale.getDefault());
List<Address> addresses = geocoder.getFromLocation(lat, lng, 1);

I prefer to use curly brackets ${} for expanding variable in string:

foo="Hello"
foo="${foo} World"
echo $foo
> Hello World

Curly brackets will fit to Continuous string usage:

foo="Hello"
foo="${foo}World"
echo $foo
> HelloWorld

Otherwise using foo = "$fooWorld" will not work.

For me it was another problem. This might be trivial for some, but it took me a while to figure out. So this answer might be helpfull to some.

I had my API_BASE_URL set to localhost:58577. The coin dropped after reading the error message for the millionth time. The problem is in the part where it says that it only supports HTTP and some other protocols. I had to change the API_BASE_URL so that it includes the protocol. So changing API_BASE_URL to http://localhost:58577 it worked perfectly.

I realise I am a little late to the party here, but I had been checking out a simple one line way to provide feedback on whether a browser is IE and what version from 10 down it was. I haven't coded this for version 11, so perhaps a little amendment will be needed for that.

However this is the code, it works as an object that has a property and a method and relies on object detection rather than scraping the navigator object (which is massively flawed as it can be spoofed).

var isIE = { browser:/*@cc_on!@*/false, detectedVersion: function () { return (typeof window.atob !== "undefined") ? 10 : (typeof document.addEventListener !== "undefined") ? 9 : (typeof document.querySelector !== "undefined") ? 8 : (typeof window.XMLHttpRequest !== "undefined") ? 7 : (typeof document.compatMode !== "undefined") ? 6 : 5; } };

The usage is isIE.browser a property that returns a boolean and relies on conditional comments the method isIE.detectedVersion() which returns a number between 5 and 10. I am making the assumption that anything lower than 6 and you are in serious old school territory and you will something more beefy than a one liner and anything higher than 10 and you are in to newer territory. I have read something about IE11 not supporting conditional comments but I've not fully investigated, that is maybe for a later date.

Anyway, as it is, and for a one liner, it will cover the basics of IE browser and version detection. It's far from perfect, but it is small and easily amended.

Just for reference, and if anyone is in any doubt on how to actually implement this then the following conditional should help.

var isIE = { browser:/*@cc_on!@*/false, detectedVersion: function () { return (typeof window.atob !== "undefined") ? 10 : (typeof document.addEventListener !== "undefined") ? 9 : (typeof document.querySelector !== "undefined") ? 8 : (typeof window.XMLHttpRequest !== "undefined") ? 7 : (typeof document.compatMode !== "undefined") ? 6 : 5; } };

/* testing IE */

if (isIE.browser) {
  alert("This is an IE browser, with a detected version of : " + isIE.detectedVersion());
}

I resolve similar problem with:

document.getElementById("xyz").style.padding = "10px 0 0 0";

Hope that helps.

function range(j, k) { 
    return Array
        .apply(null, Array((k - j) + 1))
        .map(function(_, n){ return n + j; }); 
}

this is roughly equivalent to

function range(j, k) { 
    var targetLength = (k - j) + 1;
    var a = Array(targetLength);
    var b = Array.apply(null, a);
    var c = b.map(function(_, n){ return n + j; });
    return c;
}

breaking it down:

var targetLength = (k - j) + 1;

var a = Array(targetLength);

this creates a sparse matrix of the correct nominal length. Now the problem with a sparse matrix is that although it has the correct nominal length, it has no actual elements, so, for

j = 7, k = 13

console.log(a);

gives us

Array [ <7 empty slots> ]

Then

var b = Array.apply(null, a);

passes the sparse matrix as an argument list to the Array constructor, which produces a dense matrix of (actual) length targetLength, where all elements have undefined value. The first argument is the 'this' value for the the array constructor function execution context, and plays no role here, and so is null.

So now,

 console.log(b);

yields

 Array [ undefined, undefined, undefined, undefined, undefined, undefined, undefined ]

finally

var c = b.map(function(_, n){ return n + j; });

makes use of the fact that the Array.map function passes: 1. the value of the current element and 2. the index of the current element, to the map delegate/callback. The first argument is discarded, while the second can then be used to set the correct sequence value, after adjusting for the start offset.

So then

console.log(c);

yields

 Array [ 7, 8, 9, 10, 11, 12, 13 ]

The issue is simple, npm doesn't know about ng

Just run npm link @angular/cli and it should work seamlessly.

just use os.chdir
Example:

>>> import os
>>> import subprocess
>>> # Lets Just Say WE want To List The User Folders
>>> os.chdir("/home/")
>>> subprocess.run("ls")
user1 user2 user3 user4

This might be a dead horse, another way to return 1 row when no rows exist is to UNION another query and display results when non exist in the table.

SELECT S.Status, COUNT(s.id) AS StatusCount
FROM Sites S
WHERE S.Id = @SiteId
GROUP BY s.Status
UNION ALL --UNION BACK ON TABLE WITH NOT EXISTS
SELECT 'N/A' AS Status, 0 AS StatusCount
WHERE NOT EXISTS (SELECT 1
   FROM Sites S
   WHERE S.Id = @SiteId
) 

You may wonder, why the syntax is valid (but not working as expected):

var func = p => { foo: "bar" }

It's because of JavaScript's label syntax:

So if you transpile the above code to ES5, it should look like:

var func = function (p) {
  foo:
  "bar"; //obviously no return here!
}

A simple DIY to get only long named args:

Use:

$ ./test-args.sh --a1 a1 --a2 "a 2" --a3 --a4= --a5=a5 --a6="a 6"
a1 = "a1"
a2 = "a 2"
a3 = "TRUE"
a4 = ""
a5 = "a5"
a6 = "a 6"
a7 = ""

Script:

#!/bin/bash

function main() {
    ARGS=`getArgs "$@"`

    a1=`echo "$ARGS" | getNamedArg a1`
    a2=`echo "$ARGS" | getNamedArg a2`
    a3=`echo "$ARGS" | getNamedArg a3`
    a4=`echo "$ARGS" | getNamedArg a4`
    a5=`echo "$ARGS" | getNamedArg a5`
    a6=`echo "$ARGS" | getNamedArg a6`
    a7=`echo "$ARGS" | getNamedArg a7`

    echo "a1 = \"$a1\""
    echo "a2 = \"$a2\""
    echo "a3 = \"$a3\""
    echo "a4 = \"$a4\""
    echo "a5 = \"$a5\""
    echo "a6 = \"$a6\""
    echo "a7 = \"$a7\""

    exit 0
}


function getArgs() {
    for arg in "$@"; do
        echo "$arg"
    done
}


function getNamedArg() {
    ARG_NAME=$1

    sed --regexp-extended --quiet --expression="
        s/^--$ARG_NAME=(.*)\$/\1/p  # Get arguments in format '--arg=value': [s]ubstitute '--arg=value' by 'value', and [p]rint
        /^--$ARG_NAME\$/ {          # Get arguments in format '--arg value' ou '--arg'
            n                       # - [n]ext, because in this format, if value exists, it will be the next argument
            /^--/! p                # - If next doesn't starts with '--', it is the value of the actual argument
            /^--/ {                 # - If next do starts with '--', it is the next argument and the actual argument is a boolean one
                # Then just repla[c]ed by TRUE
                c TRUE
            }
        }
    "
}


main "$@"

Alternatively you can use a "." instead of *, as this will take all the files in the working directory, include the folders and subfolders:

FROM ubuntu
COPY . /
RUN ls -la /

Excel shows 24:03 as 3 minutes when you format it as time, because 24:03 is the same as 12:03 AM (in military time).

Use General Format to Add Times

Instead of trying to format as Time, use the General Format and the following formula:

=number of minutes + (number of seconds / 60)

Ex: for 24 minutes and 3 seconds:

=24+3/60

This will give you a value of 24.05.

Do this for each time period. Let's say you enter this formula in cells A1 and A2. Then, to get the total sum of elapsed time, use this formula in cell A3:

=INT(A1+A2)+MOD(A1+A2,1)

Convert back to minutes and seconds

If you put =24+3/60 into each cell, you will have a value of 48.1 in cell A3.

Now you need to convert this back to minutes and seconds. Use the following formula in cell A4:

=MOD(A3,1)*60

This takes the decimal portion and multiples it by 60. Remember, we divided by 60 in the beginning, so to convert it back to seconds we need to multiply.

You could have also done this separately, i.e. in cell A3 use this formula:

=INT(A1+A2)

and this formula in cell A4:

=MOD(A1+A2,1)*60

Here's a screenshot showing the final formulas:

The PropertyInfo class should help you achieve this, if I understand correctly.

1. Type.GetProperties() method

   PropertyInfo[] propInfos = typeof(ReflectedType).GetProperties();
   propInfos.ToList().ForEach(p => 
       Console.WriteLine(string.Format("Property name: {0}", p.Name));
   

Is this what you need?

The following code -

element.sendKeys("");

tries to find an input tag box to enter some information, while

new Actions(driver).moveToElement(element).perform();

is more appropriate as it will work for image elements, link elements, dropdown boxes etc.

Therefore using moveToElement() method makes more sense to focus on any generic WebElement on the web page.

For an input box you will have to click() on the element to focus.

new Actions(driver).moveToElement(element).click().perform();

while for links and images the mouse will be over that particular element,you can decide to click() on it depending on what you want to do.

If the click() on an input tag does not work -

Since you want this function to be generic, you first check if the webElement is an input tag or not by -

if("input".equals(element.getTagName()){
   element.sendKeys("");
} 
else{
   new Actions(driver).moveToElement(element).perform();

}

You can make similar changes based on your preferences.

Try the following:

df[df['Col2'].isnull()]

If you don't want 3D border use:

border:#f00 1px solid;

This works for me (Excel 2013):

Public Sub StartExeWithArgument()
    Dim strProgramName As String
    Dim strArgument As String

    strProgramName = "C:\Program Files\Test\foobar.exe"
    strArgument = "/G"

    Call Shell("""" & strProgramName & """ """ & strArgument & """", vbNormalFocus)
End Sub

Bad programming practice. Using a goto function is a complete no no in C programming.
Also include header file stdlib.h by writing #include <iostream.h>for using exit() function. Also remember that exit() function takes an integer argument . Use exit(0) if the program completed successfully and exit(-1) or exit function with any non zero value as the argument if the program has error.

I use ? (0x25B8) for the right arrow, often to show a collapsed list; and I pair it with ? (0x25BE) to show the list opened up. Both are unobtrusive.

I came up with this pretty basic code. I think it could be useful to anyone.

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

You can just pass the column names as a list with specifying the axis as 0 or 1

• axis=1: Along the Rows
• axis=0: Along the Columns

• By default axis=0

  data.drop(["Colname1","Colname2","Colname3","Colname4"],axis=1)

An easier tool to monitor the tracking tags is to use the Chrome extension (probably available, or the equivalent for other browsers) - Google Tag Assistant. This will show what tags are firing, what problems it has found, and even breaks out stuff like eCommerce values for easy reading. Also works with the Google Tag Manager, and can handle multiple sets of tags on the page.

Null pointers and void pointers are completely different from each other. If we request the operating system(through malloc() in c langauge) to allocate memory for a particular data type then the operating system allocates memory in heap (if space is available in heap) and sends the address of the memory which was allocated.

When memory is allocated by os in heap then we can assign this address value in any pointer type variable of that data type. This pointer is then called a void pointer until it is not taken for any process.

When the space is not available in heap then the operating system certainly allocates memory and sends an address value of that location but this memory is not allocated in heap by the os because there is no space in heap,in this case this memory is allocated by the os in the system memory.. This memory can not be accessed by the user hence when we assign this address value in a pointer then this pointer is known as null pointer, and we cannot use this pointer. In the case of void pointer we can use it for any process in any programming language.

Follow these:

1. open your xampp control panel then click its "config"

2. choose the "Apache (httpd.conf)" and find this code below and change it into this one:

   # Change this to Listen on specific IP addresses as shown below to 
   # prevent Apache from glomming onto all bound IP addresses.
   #
   #Listen 0.0.0.0:80
   #Listen [::]:80
   Listen 80
   #
   # Dynamic Shared Object (DSO) Support
   

3. save it (ctrl + s)

4. after that, go back to xampp control panel and click again its config

5. choose "Apache (httpd-ssl.conf)" find this code below and change it again:

   # Note: Configurations that use IPv6 but not IPv4-mapped addresses need two
   #       Listen directives: "Listen [::]:443" and "Listen 0.0.0.0:443"
   #
   #Listen 0.0.0.0:443
   #Listen [::]:443
   Listen 443
   

6. save it (ctrl + s)

7. then, click the "config" (note: above the netstat) and click the "service and port settings" then save both of it.

8. finally, go to the "control panel" -> "Programs & Features" -> "Turn Windows On or Off".

9. Uncheck your "Internet Information Services" then click ok.

Just wait for it and your computer/laptop will be automatically restart and try to open again your xampp control panel then start your Apache.

Have you changed your Windows password recently, or at least the one you use to connect to your proxy?

This was my problem, and git status couldn't help me. I had to change my login credentials in the ".git/config" file to get past this error.

I have always just installed the new version on top and never had any issues. Do make sure that your path is updated to point to the new version though.

            // If the response is JSONObject instead of expected JSONArray
            Log.d("asd", "---------------- this is response : " + response);
            try {
                JSONObject serverResp = new JSONObject(response.toString());                                                
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }                   
        }
            
        @Override
        public void onSuccess(int statusCode, Header[] headers, JSONArray timeline) {
            // Pull out the first event on the public timeline
                    
        }
    });

Please grant internet permission in your manifest file.

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

you can add compile 'com.loopj.android:android-async-http:1.4.9' for Header[] and compile 'org.json:json:20160212' for JSONObject in build.gradle file if required.

Way more elegant solution than $parent.$index is using ng-init:

<ul ng-repeat="section in sections" ng-init="sectionIndex = $index">
    <li  class="section_title {{section.active}}" >
        {{section.name}}
    </li>
    <ul>
        <li class="tutorial_title {{tutorial.active}}" ng-click="loadFromMenu(sectionIndex)" ng-repeat="tutorial in section.tutorials">
            {{tutorial.name}}
        </li>
    </ul>
</ul>

On SmtpClient there is an EnableSsl property that you would set.

i.e.

SmtpClient client = new SmtpClient(exchangeServer);
client.EnableSsl = true;
client.Send(msg);

You can try this, and if it will find any space it will return the position where the first space is.

if mystring.find(' ') != -1:
    print True
else:
    print False

Facebook is using LAMP structure. Facebook’s back-end services are written in a variety of different programming languages including C++, Java, Python, and Erlang and they are used according to requirement. With LAMP Facebook uses some technologies ,to support large number of requests, like

1. Memcache - It is a memory caching system that is used to speed up dynamic database-driven websites (like Facebook) by caching data and objects in RAM to reduce reading time. Memcache is Facebook’s primary form of caching and helps alleviate the database load. Having a caching system allows Facebook to be as fast as it is at recalling your data.

2. Thrift (protocol) - It is a lightweight remote procedure call framework for scalable cross-language services development. Thrift supports C++, PHP, Python, Perl, Java, Ruby, Erlang, and others.

3. Cassandra (database) - It is a database management system designed to handle large amounts of data spread out across many servers.

4. HipHop for PHP - It is a source code transformer for PHP script code and was created to save server resources. HipHop transforms PHP source code into optimized C++. After doing this, it uses g++ to compile it to machine code.

If we go into more detail, then answer to this question go longer. We can understand more from following posts:

1. How Does Facebook Work?
2. Data Management, Facebook-style
3. Facebook database design?

I hate when sites complicate download so much and use hacks instead of a good old link.

Dead simple version:

<a href="file.zip">Start automatic download!</a>

It works! In every browser!

If you want to download a file that is usually displayed inline (such as an image) then HTML5 has a download attribute that forces download of the file. It also allows you to override filename (although there is a better way to do it):

<a href="report-generator.php" download="result.xls">Download</a>

Version with a "thanks" page:

If you want to display "thanks" after download, then use:

<a href="file.zip" 
   onclick="if (event.button==0) 
     setTimeout(function(){document.body.innerHTML='thanks!'},500)">
 Start automatic download!
</a>

Function in that setTimeout might be more advanced and e.g. download full page via AJAX (but don't navigate away from the page — don't touch window.location or activate other links).

The point is that link to download is real, can be copied, dragged, intercepted by download accelerators, gets :visited color, doesn't re-download if page is left open after browser restart, etc.

That's what I use for ImageOptim

Here is part of a line in my code that brought the warning up in NetBeans:

$page = (!empty($_GET['p'])) 

After much research and seeing how there are about a bazillion ways to filter this array, I found one that was simple. And my code works and NetBeans is happy:

$p = filter_input(INPUT_GET, 'p');
$page = (!empty($p))

You can declare multiple variables, and initialize multiple variables, but not both at the same time:

 String one,two,three;
 one = two = three = "";

However, this kind of thing (especially the multiple assignments) would be frowned upon by most Java developers, who would consider it the opposite of "visually simple".

You should use Array.prototype.reduce to do this. I did do a little JS perf test to verify that this is more performant than doing a .filter + .map.

$scope.appIds = $scope.applicationsHere.reduce(function(ids, obj){
    if(obj.selected === true){
        ids.push(obj.id);
    }
    return ids;
}, []);

Just for the sake of clarity, here's the sample .reduce I used in the JSPerf test:

  var things = [_x000D_
    {id: 1, selected: true},_x000D_
    {id: 2, selected: true},_x000D_
    {id: 3, selected: true},_x000D_
    {id: 4, selected: true},_x000D_
    {id: 5, selected: false},_x000D_
    {id: 6, selected: true},_x000D_
    {id: 7, selected: false},_x000D_
    {id: 8, selected: true},_x000D_
    {id: 9, selected: false},_x000D_
    {id: 10, selected: true},_x000D_
  ];_x000D_
  _x000D_
   _x000D_
var ids = things.reduce((ids, thing) => {_x000D_
  if (thing.selected) {_x000D_
    ids.push(thing.id);_x000D_
  }_x000D_
  return ids;_x000D_
}, []);_x000D_
_x000D_
console.log(ids)

EDIT 1

Note, As of 2/2018 Reduce + Push is fastest in Chrome and Edge, but slower than Filter + Map in Firefox

Have got the same error as in header because of failed attempt to compile my project with java 8 and then reattempting to compile with java 6. Some classes where compiled at the first attempt with 8 and did not recompile with 6. Mixed classes did not compile then. Cleaning project solved the problem. This answer is not strictly relevant to the question, but could be useful for someone.

The git-cache-meta mentioned in SO question "git - how to recover the file permissions git thinks the file should be?" (and the git FAQ) is the more staightforward approach.

The idea is to store in a .git_cache_meta file the permissions of the files and directories.
It is a separate file not versioned directly in the Git repo.

That is why the usage for it is:

$ git bundle create mybundle.bdl master; git-cache-meta --store
$ scp mybundle.bdl .git_cache_meta machine2: 
#then on machine2:
$ git init; git pull mybundle.bdl master; git-cache-meta --apply

So you:

• bundle your repo and save the associated file permissions.
• copy those two files on the remote server
• restore the repo there, and apply the permission

The syntax is:

=GOOGLEFINANCE(ticker, [attribute], [start_date], [num_days|end_date], [interval])

Sample usage:

=GOOGLEFINANCE("GOOG", "price", DATE(2014,1,1), DATE(2014,12,31), "DAILY")
=GOOGLEFINANCE("GOOG","price",TODAY()-30,TODAY())
=GOOGLEFINANCE(A2,A3)
=117.80*Index(GOOGLEFINANCE("CURRENCY:EURGBP", "close", DATE(2014,1,1)), 2, 2)

For instance if you'd like to convert the rate on specific date, here is some more advanced example:

=IF($C2 = "GBP", "", Index(GoogleFinance(CONCATENATE("CURRENCY:", C2, "GBP"), "close", DATE(year($A2), month($A2), day($A2)), DATE(year($A2), month($A2), day($A2)+1), "DAILY"), 2))

where $A2 is your date (e.g. 01/01/2015) and C2 is your currency (e.g. EUR).

See more samples at Docs editors Help at Google.

if (x & 1)
 itIsOddNumber();
else
 itIsEvenNumber();

You can simply use substring:

if(fieldName.endsWith(","))
{
  fieldName = fieldName.substring(0,fieldName.length() - 1);
}

Make sure to reassign your field after performing substring as Strings are immutable in java

It might be a bit of a overkill but I like convinience functions so take this one:

    public static void ShowFileInExplorer(FileInfo file) {
        StartProcess("explorer.exe", null, "/select, "+file.FullName.Quote());
    }
    public static Process StartProcess(FileInfo file, params string[] args) => StartProcess(file.FullName, file.DirectoryName, args);
    public static Process StartProcess(string file, string workDir = null, params string[] args) {
        ProcessStartInfo proc = new ProcessStartInfo();
        proc.FileName = file;
        proc.Arguments = string.Join(" ", args);
        Logger.Debug(proc.FileName, proc.Arguments); // Replace with your logging function
        if (workDir != null) {
            proc.WorkingDirectory = workDir;
            Logger.Debug("WorkingDirectory:", proc.WorkingDirectory); // Replace with your logging function
        }
        return Process.Start(proc);
    }

This is the extension function I use as <string>.Quote():

static class Extensions
{
    public static string Quote(this string text)
    {
        return SurroundWith(text, "\"");
    }
    public static string SurroundWith(this string text, string surrounds)
    {
        return surrounds + text + surrounds;
    }
}

You can use the following line of code in the activity's onCreate method to make sure the keyboard only pops up when a user clicks into an EditText

this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN); 

The line

SELECT  @Prefix + LEN(CAST(@maxCode AS VARCHAR(10))+1) + CAST(@maxCode AS VARCHAR(100))

is wrong.

@Prefix is 'J' and LEN(...anything...) is an int, hence the type mismatch.

It seems to me, you actually want to do,

SELECT
        @maxCode = MAX(
            CAST(SUBSTRING(
                Voucher_No,
                @startFrom + 1,
                LEN(Voucher_No) - (@startFrom + 1)) AS INT)
    FROM
        dbo.Journal_Entry;

SELECT  @Prefix + CAST(@maxCode AS VARCHAR(10));

but, I couldn't say. If you illustrated before and after data, it would help.

In Java 8, you can use Lambda expressions to make it simpler.

Close application

JButton btnClose = new JButton("Close");
btnClose.addActionListener(e -> System.exit(0));

Close window

JButton btnClose = new JButton("Close");
btnClose.addActionListener(e -> this.dispose());

You have to free() the allocated memory in exact reverse order of how it was allocated using malloc().

Note that You should free the memory only after you are done with your usage of the allocated pointers.

memory allocation for 1D arrays:

    buffer = malloc(num_items*sizeof(double));

memory deallocation for 1D arrays:

    free(buffer);

memory allocation for 2D arrays:

    double **cross_norm=(double**)malloc(150 * sizeof(double *));
    for(i=0; i<150;i++)
    {
        cross_norm[i]=(double*)malloc(num_items*sizeof(double));
    }

memory deallocation for 2D arrays:

    for(i=0; i<150;i++)
    {
        free(cross_norm[i]);
    }

    free(cross_norm);

if you only want the last line deleted output without changing the file itself do

sed -e '$ d' foo.txt

if you want to delete the last line of the input file itself do

sed -i '' -e '$ d' foo.txt

You could specify per project how much heap space your project wants

Following is for Eclipse Helios/Juno/Kepler:

Right mouse click on

 Run As - Run Configuration - Arguments - Vm Arguments, 

then add this

-Xmx2048m

Use _.forOwn().

_.forOwn(obj, function(value, key) { } );

Note that forOwn checks hasOwnProperty, as you usually need to do when looping over an object's properties. forIn does not do this check.

Add attributed text color in swift code.

Swift 4:

  let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
  let attributedStringColor = [NSAttributedStringKey.foregroundColor : greenColor];

  let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor)
  label.attributedText = attributedString

for Swift 3:

  let greenColor = UIColor(red: 10/255, green: 190/255, blue: 50/255, alpha: 1)
  let attributedStringColor : NSDictionary = [NSForegroundColorAttributeName : greenColor];


  let attributedString = NSAttributedString(string: "Hello World!", attributes: attributedStringColor as? [String : AnyObject])
  label.attributedText = attributedString 

If your instance is down, you are look for version information in alert.log

Or another crude way is to look into Oracle binary, If DB in hosted on Linux, try strings on Oracle binary.

strings -a $ORACLE_HOME/bin/oracle |grep RDBMS | grep RELEASE

If your images are in a separate directory of your css file and you want the relative path begins from the root of your web site:

background-image: url('/Images/bgi.png');

You could put your data into a recordset and use Excel's CopyFromRecordset Method - it's much faster than populating cell-by-cell.

You can create a recordset from a dataset using this code. You will have to do some trials to see if using this method is faster than what you are currently doing.

The first solution works well. I want to add one small detail here. Make sure the variable you are trying to replace/update it will has to be a type str. My mysql type is decimal but I had to make the parameter variable as str to be able to execute the query.

temp = "100"
myCursor.execute("UPDATE testDB.UPS SET netAmount = %s WHERE auditSysNum = '42452'",(temp,))
myCursor.execute(var)

I would suggest doing this in a more functional style :P

function CreateMessageboard(BoardMessages) {
  var htmlMessageboardString = BoardMessages
   .map(function(BoardMessage) {
     return MessageToHTMLString(BoardMessage);
   })
   .join('');
}

Try this

See PEP 308 for more info.

GLM has good example of rotation : http://glm.g-truc.net/code.html

glm::mat4 Projection = glm::perspective(45.0f, 4.0f / 3.0f, 0.1f, 100.f);
glm::mat4 ViewTranslate = glm::translate(
    glm::mat4(1.0f),
    glm::vec3(0.0f, 0.0f, -Translate)
);
glm::mat4 ViewRotateX = glm::rotate(
    ViewTranslate,
    Rotate.y,
    glm::vec3(-1.0f, 0.0f, 0.0f)
);
glm::mat4 View = glm::rotate(
    ViewRotateX,
    Rotate.x,
    glm::vec3(0.0f, 1.0f, 0.0f)
);
glm::mat4 Model = glm::scale(
    glm::mat4(1.0f),
    glm::vec3(0.5f)
);
glm::mat4 MVP = Projection * View * Model;
glUniformMatrix4fv(LocationMVP, 1, GL_FALSE, glm::value_ptr(MVP));

Try using the html() function.

$('#<%=Label1.ClientID%>').html();

You're also missing the # to make it an ID you're searching for. Without the #, it's looking for a tag type.

'Caret' package provides methods for preprocessing data (e.g. centering and scaling). You could also use the following code:

library(caret)
# Assuming goal class is column 10
preObj <- preProcess(data[, -10], method=c("center", "scale"))
newData <- predict(preObj, data[, -10])

Change the code like this. It works perfectly:

public function uploadImageFile() //gallery insert
{ 
    if($_SERVER['REQUEST_METHOD'] == 'POST') {
    $new_image_name = time() . str_replace(str_split(' ()\\/,:*?"<>|'), '', 
    $_FILES['image_file']['name']);
    $config['upload_path'] = 'uploads/gallery/'; 
    $config['allowed_types'] = 'gif|jpg|png|bmp|jpeg';
    $config['file_name'] = $new_image_name;
    $config['max_size']  = '0';
    $config['max_width']  = '0';
    $config['max_height']  = '0';
    $config['$min_width'] = '0';
    $config['min_height'] = '0';
    $this->load->library('upload', $config);
    $upload = $this->upload->do_upload('image_file');
    $title=$this->input->post('title');
    $value=array('title'=>$title,'image_name'=>
    $new_image_name,'crop_name'=>$crop_image_name);}

For a repository setting solution, that can be redistributed to all developers, check out the text attribute in the .gitattributes file. This way, developers dont have to manually set their own line endings on the repository, and because different repositories can have different line ending styles, global core.autocrlf is not the best, at least in my opinion.

For example unsetting this attribute on a given path [. - text] will force git not to touch line endings when checking in and checking out. In my opinion, this is the best behavior, as most modern text editors can handle both type of line endings. Also, if you as a developer still want to do line ending conversion when checking in, you can still set the path to match certain files or set the eol attribute (in .gitattributes) on your repository.

Also check out this related post, which describes .gitattributes file and text attribute in more detail: What's the best CRLF (carriage return, line feed) handling strategy with Git?

Use DateTime.ParseExact.

this.Text="22/11/2009";

DateTime date = DateTime.ParseExact(this.Text, "dd/MM/yyyy", null);

This is a case where you mixed up default exports and named exports.

When dealing with the named exports, if you try to import them you should use curly braces as below,

import { Home } from './layouts/Home'; // if the Home is a named export

In your case the Home was exported as a default one. This is the one that will get imported from the module, when you don’t specify a certain name of a certain piece of code. When you import, and omit the curly braces, it will look for the default export in the module you’re importing from. So your import should be,

import Home from './layouts/Home'; // if the Home is a default export

The most frequent cause of "no debugging symbols found" when -g is present is that there is some "stray" -s or -S argument somewhere on the link line.

From man ld:

   -s
   --strip-all
       Omit all symbol information from the output file.

   -S
   --strip-debug
       Omit debugger symbol information (but not all symbols) from the output file.

You can use Substring:

string b = a.Substring(0,3);

Setting line-height: 0px; fixed it for me in Chrome

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

14. Enyo - front-end library aimed at mobile and TV apps (e.g. large touch-friendly controls). Developed by LG Electronix and Apache-licensed on GitHub.

15. The radical Cappuccino - Objective-J (a superset of JavaScript) instead of HTML+CSS+DOM

16. Mochaui, MooTools UI Library User Interface Library. <300 GitHub stars.

17. CrossUI - cross-browser JS framework to develop and package the exactly same code and UI into Web Apps, Native Desktop Apps (Windows, OS X, Linux) and Mobile Apps (iOS, Android, Windows Phone, BlackBerry). Open sourced LGPL3. Featured RAD tool (form builder etc.). The UI looks desktop-, not web-oriented. Actively developed, small community. No presence on GitHub.

18. ZinoUI - simple widgets. The DataTable, for instance, doesn't even support sorting.

19. Wijmo - good-looking commercial widgets, with old (jQuery UI) widgets open-sourced on GitHub (their development stopped in 2013). Developed by ComponentOne, a division of GrapeCity. See Wijmo Complete vs. Open.

20. CxJS - commercial JS framework based on React, Babel and webpack offering form elements, form validation, advanced grid control, navigational elements, tooltips, overlays, charts, routing, layout support, themes, culture dependent formatting and more.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

1. Zebra - demos

No longer developed as of Dec 2014

1. Yahoo! User Interface - YUI, launched in 2005, but no longer maintained by the core contributors - see the announcement, which highlights reasons why large UI widget libraries are perceived as walled gardens that developers don't want to be locked into.
2. echo3, GitHub. Supports writing either server-side Java applications that don't require developer knowledge of HTML, HTTP, or JavaScript, or client-side JavaScript-based applications do not require a server, but can communicate with one via AJAX. Last update: July 2013.
3. ampleSDK
4. Simpler widgets livepipe.net
5. JxLib
6. rialto
7. Simple UI kit
8. Prototype-ui

I could be wrong but I thought it used IE's proxy settings.

If it sees that you need to login it opens a dialog and asks you to do so (login that is).

Please see the description of this here -> http://docs.nuget.org/docs/release-notes/nuget-1.5

IE11 does implement String.prototype.includes so why not using the official Polyfill?

  if (!String.prototype.includes) {
    String.prototype.includes = function(search, start) {
      if (typeof start !== 'number') {
        start = 0;
      }

      if (start + search.length > this.length) {
        return false;
      } else {
        return this.indexOf(search, start) !== -1;
      }
    };
  }

You need to add your tiles into your resource bundle. I mean add all those files to your project make sure to copy all files to project directory option checked.

Was working on similar task and came across this query, by following few links and working on few exercises for nltk the below code worked for me like magic.

from nltk.tokenize import sent_tokenize 
  
text = "Hello everyone. Welcome to GeeksforGeeks. You are studying NLP article"
sent_tokenize(text) 

output:

['Hello everyone.',
 'Welcome to GeeksforGeeks.',
 'You are studying NLP article']

When Port xxxx is already being used, there's always a PID (Process Id) elaborated with the error. Simply go to the task manager on the machine you are running the application, click on details, and you will identify what the other application is. You can then decide whether you want to end that process or not

It probably means that mongodb is not running. You will have to enable it through the command line or on windows run services.msc and enable mongodb.

Instead of using a Dictionary, why not convert to an ILookup?

var myData = new[]{new {a=1,b="frog"}, new {a=1,b="cat"}, new {a=2,b="giraffe"}};
ILookup<int,string> lookup = myData.ToLookup(x => x.a, x => x.b);
IEnumerable<string> allOnes = lookup[1]; //enumerable of 2 items, frog and cat

An ILookup is an immutable data structure that allows multiple values per key. Probably not much use if you need to add items at different times, but if you have all your data up-front, this is definitely the way to go.

You may group your library.available_until wheres area by grouping method of Codeigniter for without disable escaping where clauses.

$this->db
    ->select('*')
    ->from('library')
    ->where('library.rating >=', $form['slider'])
    ->where('library.votes >=', '1000')
    ->where('library.language !=', 'German')
    ->group_start() //this will start grouping
    ->where('library.available_until >=', date("Y-m-d H:i:s"))
    ->or_where('library.available_until =', "00-00-00 00:00:00")
    ->group_end() //this will end grouping
    ->where('library.release_year >=', $year_start)
    ->where('library.release_year <=', $year_end)
    ->join('rating_repo', 'library.id = rating_repo.id')

Though not extremely performant, the only readable solution is:

  // Split by separator and pick the first one.
  // This has all the characters till null, excluding null itself.
  retByteArray := bytes.Split(byteArray[:], []byte{0}) [0]

  // OR

  // If you want a true C-like string, including the null character
  retByteArray := bytes.SplitAfter(byteArray[:], []byte{0}) [0]

A full example to have a C-style byte array:

package main

import (
    "bytes"
    "fmt"
)

func main() {
    var byteArray = [6]byte{97,98,0,100,0,99}

    cStyleString := bytes.SplitAfter(byteArray[:], []byte{0}) [0]
    fmt.Println(cStyleString)
}

A full example to have a Go style string excluding the nulls:

package main

import (
    "bytes"
    "fmt"
)

func main() {
    var byteArray = [6]byte{97, 98, 0, 100, 0, 99}

    goStyleString := string(bytes.Split(byteArray[:], []byte{0}) [0])
    fmt.Println(goStyleString)
}

This allocates a slice of slice of bytes. So keep an eye on performance if it is used heavily or repeatedly.
