If you look at the output you receive from print() and also in your Traceback, you'll see the value you get back is not a string, it's a bytes object (prefixed by b):

b'{\n  "note":"This file    .....

If you fetch the URL using a tool such as curl -v, you will see that the content type is

Content-Type: application/json; charset=utf-8

So it's JSON, encoded as UTF-8, and Python is considering it a byte stream, not a simple string. In order to parse this, you need to convert it into a string first.

Change the last line of code to this:

info = json.loads(js.decode("utf-8"))

If you're using a table view to display Settings and other options (like the built-in Settings app does), then you can set your Table View Content to Static Cells under the Attributes Inspector. Also, to do this, you must embedded your Table View in a UITableViewController instance.

The python error says that wordInput is not an iterable -> it is of NoneType.

If you print wordInput before the offending line, you will see that wordInput is None.

Since wordInput is None, that means that the argument passed to the function is also None. In this case word. You assign the result of pickEasy to word.

The problem is that your pickEasy function does not return anything. In Python, a method that didn't return anything returns a NoneType.

I think you wanted to return a word, so this will suffice:

def pickEasy():
    word = random.choice(easyWords)
    word = str(word)
    for i in range(1, len(word) + 1):
        wordCount.append("_")
    return word

you can do

followers_df.index = range(20)

I spent a lot of time developing various reports. So, now I have an idea - create a web framework for building web reports. I have started here:

https://github.com/ColdSIce/ReportUI

Now it is an angular 4 module. You can pass your json data to TableLayoutComponent and get a HTML table as result. Table already has fixed header. Also you can fix some your columns by default or by click. More there, you can customize table properties like background-color, font-color, row-height etc.

If you are interested you can join me in this project and help.

Why such complications?

public static GregorianCalendar convertFromDMY(String dd_mm_yy) throws ParseException 
{
    SimpleDateFormat fmt = new SimpleDateFormat("dd-MMM-yyyy");
    Date date = fmt.parse(dd_mm_yy);
    GregorianCalendar cal = GregorianCalendar.getInstance();
    cal.setTime(date);
    return cal;
}

Most browsers will simply ignore any NON-hex values in your color string, substituting non-hex digits with zeros.

ChuCknorris translates to c00c0000000. At this point, the browser will divide the string into three equal sections, indicating Red, Green and Blue values: c00c 0000 0000. Extra bits in each section will be ignored, which makes the final result #c00000 which is a reddish color.

Note, this does not apply to CSS color parsing, which follow the CSS standard.

<p><font color='chucknorris'>Redish</font></p>_x000D_
<p><font color='#c00000'>Same as above</font></p>_x000D_
<p><span style="color: chucknorris">Black</span></p>

Use the MultiValueDict's get method. This is also present on standard dicts and is a way to fetch a value while providing a default if it does not exist.

is_private = request.POST.get('is_private', False)

Generally,

my_var = dict.get(<key>, <default>)

Write it as below

<script language="javascript">
var visitorName = 'Chuck';
var myOldString = 'Hello username. I hope you enjoy your stay username.';

var myNewString = myOldString.replace('username', visitorName);

document.write('Old String = ' + myOldString);
document.write('<br/>New string = ' + myNewString);
</script>

My implementation:

import math
n = 100
marked = {}
for i in range(2, int(math.sqrt(n))):
    if not marked.get(i):
        for x in range(i * i, n, i):
            marked[x] = True

for i in range(2, n):
    if not marked.get(i):
        print i

For scripting purposes, I've found that curl command can do it, for example:

$ curl -s localhost:80 >/dev/null && echo Connected. || echo Fail.
Connected.
$ curl -s localhost:123 >/dev/null && echo Connected. || echo Fail.
Fail.

Possibly it may not won't work for all services, as curl can return different error codes in some cases (as per comment), so adding the following condition could work in reliable way:

[ "$(curl -sm5 localhost:8080 >/dev/null; echo $?)" != 7 ] && echo OK || echo FAIL

^{Note: Added -m5 to set maximum connect timeout of 5 seconds.}

If you would like to check also whether host is valid, you need to check for 6 exit code as well:

$ curl -m5 foo:123; [ $? != 6 -a $? != 7 ] && echo OK || echo FAIL
curl: (6) Could not resolve host: foo
FAIL

To troubleshoot the returned error code, simply run: curl host:port, e.g.:

$ curl localhost:80
curl: (7) Failed to connect to localhost port 80: Connection refused

See: man curl for full list of exit codes.

Oracle does use double-quotes, but you most likely need to place the object name in upper case, e.g. "TABLE". By default, if you create an object without double quotes, e.g.

CREATE TABLE table AS ...

Oracle would create the object as upper case. However, the referencing is not case sensitive unless you use double-quotes!

Use:

select * from mytest
EXEC sp_rename 'mytest.eid', 'id', 'COLUMN'
alter table mytest add id int not null identity(1,1)
update mytset set eid=id
ALTER TABLE mytest DROP COLUMN eid

ALTER TABLE [dbo].[yourtablename] ADD DEFAULT (getdate()) FOR [yourfieldname]

It's working 100%.

VERSION NOTE: You must be using SQL Server 2005 or greater with Compatibility Level set to 90 or greater for this solution.

See this MSDN article for the first example of creating a user-defined aggregate function that concatenates a set of string values taken from a column in a table.

My humble recommendation would be to leave out the appended comma so you can use your own ad-hoc delimiter, if any.

Referring to the C# version of Example 1:

change:  this.intermediateResult.Append(value.Value).Append(',');
    to:  this.intermediateResult.Append(value.Value);

And

change:  output = this.intermediateResult.ToString(0, this.intermediateResult.Length - 1);
    to:  output = this.intermediateResult.ToString();

That way when you use your custom aggregate, you can opt to use your own delimiter, or none at all, such as:

SELECT dbo.CONCATENATE(column1 + '|') from table1

NOTE: Be careful about the amount of the data you attempt to process in your aggregate. If you try to concatenate thousands of rows or many very large datatypes you may get a .NET Framework error stating "[t]he buffer is insufficient."

A global Mutex is not only to ensure to have only one instance of an application. I personally prefer using Microsoft.VisualBasic to ensure single instance application like described in What is the correct way to create a single-instance WPF application? (Dale Ragan answer)... I found that's easier to pass arguments received on new application startup to the initial single instance application.

But regarding some previous code in this thread, I would prefer to not create a Mutex each time I want to have a lock on it. It could be fine for a single instance application but in other usage it appears to me has overkill.

That's why I suggest this implementation instead:

Usage:

static MutexGlobal _globalMutex = null;
static MutexGlobal GlobalMutexAccessEMTP
{
    get
    {
        if (_globalMutex == null)
        {
            _globalMutex = new MutexGlobal();
        }
        return _globalMutex;
    }
}

using (GlobalMutexAccessEMTP.GetAwaiter())
{
    ...
}

I expand on spectra‘s answer so people don’t have to try it for themselves.

This was done on Oracle Database 11g Express Edition Release 11.2.0.2.0 - Production.

CREATE TABLE CUSTOMERS
(
  CUSTOMER_ID NUMBER NOT NULL,
  FOO FLOAT NOT NULL,
  JOIN_DATE DATE NOT NULL,
  CUSTOMER_STATUS VARCHAR2(8) NOT NULL,

  CREDITRATING VARCHAR2(10)
);

select column_name, data_type, nullable, data_length, data_precision, data_scale
from user_tab_columns where table_name ='CUSTOMERS'; 

Which yields

I have found that the best approach to search for a character in a very large string (that is 1 000 000 characters long, for example) is to use the replace() method.

window.count_replace = function (str, schar) {
    return str.length - str.replace(RegExp(schar), '').length;
};

You can see yet another JSPerf suite to test this method along with other methods of finding a character in a string.

Do not use regular expressions to parse HTML.

But if you ever need to find all regexp matches in a string, use the findall function.

import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)

# Output: ['Form 1', 'Form 2']

TL;DR

The @Autowired annotation spares you the need to do the wiring by yourself in the XML file (or any other way) and just finds for you what needs to be injected where and does that for you.

Full explanation

The @Autowired annotation allows you to skip configurations elsewhere of what to inject and just does it for you. Assuming your package is com.mycompany.movies you have to put this tag in your XML (application context file):

<context:component-scan base-package="com.mycompany.movies" />

This tag will do an auto-scanning. Assuming each class that has to become a bean is annotated with a correct annotation like @Component (for simple bean) or @Controller (for a servlet control) or @Repository (for DAO classes) and these classes are somewhere under the package com.mycompany.movies, Spring will find all of these and create a bean for each one. This is done in 2 scans of the classes - the first time it just searches for classes that need to become a bean and maps the injections it needs to be doing, and on the second scan it injects the beans. Of course, you can define your beans in the more traditional XML file or with an @Configuration class (or any combination of the three).

The @Autowired annotation tells Spring where an injection needs to occur. If you put it on a method setMovieFinder it understands (by the prefix set + the @Autowired annotation) that a bean needs to be injected. In the second scan, Spring searches for a bean of type MovieFinder, and if it finds such bean, it injects it to this method. If it finds two such beans you will get an Exception. To avoid the Exception, you can use the @Qualifier annotation and tell it which of the two beans to inject in the following manner:

@Qualifier("redBean")
class Red implements Color {
   // Class code here
}

@Qualifier("blueBean")
class Blue implements Color {
   // Class code here
}

Or if you prefer to declare the beans in your XML, it would look something like this:

<bean id="redBean" class="com.mycompany.movies.Red"/>

<bean id="blueBean" class="com.mycompany.movies.Blue"/>

In the @Autowired declaration, you need to also add the @Qualifier to tell which of the two color beans to inject:

@Autowired
@Qualifier("redBean")
public void setColor(Color color) {
  this.color = color;
}

If you don't want to use two annotations (the @Autowired and @Qualifier) you can use @Resource to combine these two:

@Resource(name="redBean")
public void setColor(Color color) {
  this.color = color;
}

The @Resource (you can read some extra data about it in the first comment on this answer) spares you the use of two annotations and instead, you only use one.

I'll just add two more comments:

1. Good practice would be to use @Inject instead of @Autowired because it is not Spring-specific and is part of the JSR-330 standard.
2. Another good practice would be to put the @Inject / @Autowired on a constructor instead of a method. If you put it on a constructor, you can validate that the injected beans are not null and fail fast when you try to start the application and avoid a NullPointerException when you need to actually use the bean.

Update: To complete the picture, I created a new question about the @Configuration class.

Try to add the suggested code to the TextChanged event:

private void textBox1_TextChanged(object sender, EventArgs e)
{
  textBox1.SelectionStart = textBox1.Text.Length;
  textBox1.ScrollToCaret();
}

There are several ways that you can transform this data. In your original post, you stated that PIVOT seems too complex for this scenario, but it can be applied very easily using both the UNPIVOT and PIVOT functions in SQL Server.

However, if you do not have access to those functions this can be replicated using UNION ALL to UNPIVOT and then an aggregate function with a CASE statement to PIVOT:

Create Table:

CREATE TABLE yourTable([color] varchar(5), [Paul] int, [John] int, [Tim] int, [Eric] int);

INSERT INTO yourTable
    ([color], [Paul], [John], [Tim], [Eric])
VALUES
    ('Red', 1, 5, 1, 3),
    ('Green', 8, 4, 3, 5),
    ('Blue', 2, 2, 9, 1);

Union All, Aggregate and CASE Version:

select name,
  sum(case when color = 'Red' then value else 0 end) Red,
  sum(case when color = 'Green' then value else 0 end) Green,
  sum(case when color = 'Blue' then value else 0 end) Blue
from
(
  select color, Paul value, 'Paul' name
  from yourTable
  union all
  select color, John value, 'John' name
  from yourTable
  union all
  select color, Tim value, 'Tim' name
  from yourTable
  union all
  select color, Eric value, 'Eric' name
  from yourTable
) src
group by name

See SQL Fiddle with Demo

The UNION ALL performs the UNPIVOT of the data by transforming the columns Paul, John, Tim, Eric into separate rows. Then you apply the aggregate function sum() with the case statement to get the new columns for each color.

Unpivot and Pivot Static Version:

Both the UNPIVOT and PIVOT functions in SQL server make this transformation much easier. If you know all of the values that you want to transform, you can hard-code them into a static version to get the result:

select name, [Red], [Green], [Blue]
from
(
  select color, name, value
  from yourtable
  unpivot
  (
    value for name in (Paul, John, Tim, Eric)
  ) unpiv
) src
pivot
(
  sum(value)
  for color in ([Red], [Green], [Blue])
) piv

See SQL Fiddle with Demo

The inner query with the UNPIVOT performs the same function as the UNION ALL. It takes the list of columns and turns it into rows, the PIVOT then performs the final transformation into columns.

Dynamic Pivot Version:

If you have an unknown number of columns (Paul, John, Tim, Eric in your example) and then an unknown number of colors to transform you can use dynamic sql to generate the list to UNPIVOT and then PIVOT:

DECLARE @colsUnpivot AS NVARCHAR(MAX),
    @query  AS NVARCHAR(MAX),
    @colsPivot as  NVARCHAR(MAX)

select @colsUnpivot = stuff((select ','+quotename(C.name)
         from sys.columns as C
         where C.object_id = object_id('yourtable') and
               C.name <> 'color'
         for xml path('')), 1, 1, '')

select @colsPivot = STUFF((SELECT  ',' 
                      + quotename(color)
                    from yourtable t
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,1,'')


set @query 
  = 'select name, '+@colsPivot+'
      from
      (
        select color, name, value
        from yourtable
        unpivot
        (
          value for name in ('+@colsUnpivot+')
        ) unpiv
      ) src
      pivot
      (
        sum(value)
        for color in ('+@colsPivot+')
      ) piv'

exec(@query)

The dynamic version queries both yourtable and then the sys.columns table to generate the list of items to UNPIVOT and PIVOT. This is then added to a query string to be executed. The plus of the dynamic version is if you have a changing list of colors and/or names this will generate the list at run-time.

All three queries will produce the same result:

| NAME | RED | GREEN | BLUE |
-----------------------------
| Eric |   3 |     5 |    1 |
| John |   5 |     4 |    2 |
| Paul |   1 |     8 |    2 |
|  Tim |   1 |     3 |    9 |

If you really want them to have ALL rights:

use YourDatabase
go
exec sp_addrolemember 'db_owner', 'UserName'
go

You can use below code snippet to read line by line, till end of file

line = obj.readline()
while(line != ''):

    # Do Something

    line = obj.readline()

And has precedence over Or, so, even if a <=> a1 Or a2

Where a And b 

is not the same as

Where a1 Or a2 And b,

because that would be Executed as

Where a1 Or (a2 And b)

and what you want, to make them the same, is the following (using parentheses to override rules of precedence):

 Where (a1 Or a2) And b

Here's an example to illustrate:

Declare @x tinyInt = 1
Declare @y tinyInt = 0
Declare @z tinyInt = 0

Select Case When @x=1 OR @y=1 And @z=1 Then 'T' Else 'F' End -- outputs T
Select Case When (@x=1 OR @y=1) And @z=1 Then 'T' Else 'F' End -- outputs F

For those who like to consult references (in alphabetic order):

• Microsoft Transact-SQL operator precedence
• Oracle MySQL 9 operator precedence
• Oracle 10g condition precedence
• PostgreSQL operator Precedence
• SQL as understood by SQLite

Let us consider a table which stores the shift details

Please check the SQL queries to generate table and finding the schedule based on an input(time)

Declaring the Table variable

declare @MyShiftTable table(MyShift int,StartTime time,EndTime time)

Adding values to Table variable

insert into @MyShiftTable select 1,'01:17:40.3530000','02:17:40.3530000'
insert into @MyShiftTable select 2,'09:17:40.3530000','03:17:40.3530000'
insert into @MyShiftTable select 3,'10:17:40.3530000','18:17:40.3530000'

Creating another table variable with an additional field named "Flag"

declare @Temp table(MyShift int,StartTime time,EndTime time,Flag int)

Adding values to temporary table with swapping the start and end time

insert into @Temp select MyShift,case when (StartTime>EndTime) then EndTime else StartTime end,case when (StartTime>EndTime) then StartTime else EndTime end,case when (StartTime>EndTime) then 1 else 0 end from @MyShiftTable

Creating input variable to find the Shift

declare @time time=convert(time,'10:12:40.3530000')

Query to find the shift corresponding to the time supplied

select myShift from @Temp where
(@time between StartTime and EndTime and Flag=0) or (@time not between StartTime and EndTime and Flag=1)

Short answer

hibernate.dialect property makes Hibernate to generate the appropriate SQL statements for the chosen database.

One more way to do this is:

git config remote.origin.url https://github.com/abc/abc.git

To see the existing URL just do:

git config remote.origin.url

In case of SQL Server, this should work

SELECT CONVERT(VARCHAR(8),GETDATE(),108) AS HourMinuteSecond

Intrinsic Content Size of Multi-Line Text

The intrinsic content size of UILabel and NSTextField is ambiguous for multi-line text. The height of the text depends on the width of the lines, which is yet to be determined when solving the constraints. In order to solve this problem, both classes have a new property called preferredMaxLayoutWidth, which specifies the maximum line width for calculating the intrinsic content size.

Since we usually don’t know this value in advance, we need to take a two-step approach to get this right. First we let Auto Layout do its work, and then we use the resulting frame in the layout pass to update the preferred maximum width and trigger layout again.

- (void)layoutSubviews
{
    [super layoutSubviews];
    myLabel.preferredMaxLayoutWidth = myLabel.frame.size.width;
    [super layoutSubviews];
}

The first call to [super layoutSubviews] is necessary for the label to get its frame set, while the second call is necessary to update the layout after the change. If we omit the second call we get a NSInternalInconsistencyException error, because we’ve made changes in the layout pass which require updating the constraints, but we didn’t trigger layout again.

We can also do this in a label subclass itself:

@implementation MyLabel
- (void)layoutSubviews
{
    self.preferredMaxLayoutWidth = self.frame.size.width;
    [super layoutSubviews];
}
@end

In this case, we don’t need to call [super layoutSubviews] first, because when layoutSubviews gets called, we already have a frame on the label itself.

To make this adjustment from the view controller level, we hook into viewDidLayoutSubviews. At this point the frames of the first Auto Layout pass are already set and we can use them to set the preferred maximum width.

- (void)viewDidLayoutSubviews
{
    [super viewDidLayoutSubviews];
    myLabel.preferredMaxLayoutWidth = myLabel.frame.size.width;
    [self.view layoutIfNeeded];
}

Lastly, make sure that you don’t have an explicit height constraint on the label that has a higher priority than the label’s content compression resistance priority. Otherwise it will trump the calculated height of the content. Make sure to check all the constraints that can affect label's height.

you just need to import this

   import org.json.JSONObject;


  constructing the String that you want to send

 JSONObject param=new JSONObject();
 JSONObject post=new JSONObject();

im using two object because you can have an jsonObject within another

post.put("username(here i write the key)","someusername"(here i put the value);
post.put("message","this is a sweet message");
post.put("image","http://localhost/someimage.jpg");
post.put("time":  "present time");

then i put the post json inside another like this

  param.put("post",post);

this is the method that i use to make a request

 makeRequest(param.toString());

public JSONObject makeRequest(String param)
{
    try
    {

setting the connection

        urlConnection = new URL("your url");
        connection = (HttpURLConnection) urlConnection.openConnection();
        connection.setDoOutput(true);
        connection.setRequestMethod("POST");
        connection.setRequestProperty("Content-type", "application/json;charset=UTF-8");
        connection.setReadTimeout(60000);
        connection.setConnectTimeout(60000);
        connection.connect();

setting the outputstream

        dataOutputStream = new DataOutputStream(connection.getOutputStream());

i use this to see in the logcat what i am sending

        Log.d("OUTPUT STREAM  " ,param);
        dataOutputStream.writeBytes(param);
        dataOutputStream.flush();
        dataOutputStream.close();

        InputStream in = new BufferedInputStream(connection.getInputStream());
        BufferedReader reader = new BufferedReader(new InputStreamReader(in));
        result = new StringBuilder();
        String line;

here the string is constructed

        while ((line = reader.readLine()) != null)
        {
            result.append(line);
        }

i use this log to see what its comming in the response

         Log.d("INPUTSTREAM: ",result.toString());

instancing a json with the String that contains the server response

        jResponse=new JSONObject(result.toString());

    }
    catch (IOException e) {
        e.printStackTrace();
        return jResponse=null;
    } catch (JSONException e)
    {
        e.printStackTrace();
        return jResponse=null;
    }
    connection.disconnect();
    return jResponse;
}

SELECT * INTO table2 FROM table1;

if you use Sql Server

delete from Table where id between 79 and 296

After your edit : you now clarified that you want :

ID (>79 AND < 296)

So use this :

delete from Table where id > 79 and id < 296

In Python 2.x, you could use the format specifiers <B for unsigned bytes, and <b for signed bytes with struct.unpack/struct.pack.

E.g:

Let x = '\xff\x10\x11'

data_ints = struct.unpack('<' + 'B'*len(x), x) # [255, 16, 17]

And:

data_bytes = struct.pack('<' + 'B'*len(data_ints), *data_ints) # '\xff\x10\x11'

That * is required!

See https://docs.python.org/2/library/struct.html#format-characters for a list of the format specifiers.

Try using the decimal entity   instead of the named entity. If that doesn't work, you should be able to simply use the unicode character for a non-breaking space instead of the   entity.

(Note: I did not try this in XPather, but I did try it in Oxygen.)

No, it won't wait.

You could use performSelectorOnMainThread:withObject:waitUntilDone:.

There are actually people wanting to write with two-way binding, but React does not work in that way.

That's true, there are people who want to write with two-way data binding. And there's nothing fundamentally wrong with React preventing them from doing so. I wouldn't recommend them to use deprecated React mixin for that, though. Because it looks so much better with some third-party packages.

import { LinkedComponent } from 'valuelink'

class Test extends LinkedComponent {
    state = { a : "Hi there! I'm databinding demo!" };

    render(){
        // Bind all state members...
        const { a } = this.linkAll();

        // Then, go ahead. As easy as that.
        return (
             <input type="text" ...a.props />
        )
    }
}

The thing is that the two-way data binding is the design pattern in React. Here's my article with a 5-minute explanation on how it works

This might make a little more sense from a coding perspective (available with ant-contrib: http://ant-contrib.sourceforge.net/):

<target name="someTarget">
    <if>
        <available file="abc.txt"/>
        <then>
            ...
        </then>
        <else>
            ...
        </else>
    </if>
</target>

Here, I have generalized write the code for N tap counts. The code is similarly written for the Enable Developer option in android device phone. Even you can use this to enable features while developer testing the app.

 private Handler tapHandler;
 private Runnable tapRunnable;
 private int mTapCount = 0;
 private int milSecDealy = 2000;

onCreate(){
 ...
tapHandler = new Handler(Looper.getMainLooper());

 }

Call askToExit() on backpress or logout option.

private void askToExit() {
   if (mTapCount >= 2) {
    releaseTapValues();
    /* ========= Exit = TRUE  =========  */
   }

   mTapCount++;
   validateTapCount();
  }


  /* Check with null to avoid create multiple instances of the runnable */
  private void validateTapCount() {
   if (tapRunnable == null) {
    tapRunnable = new Runnable() {
     @Override
     public void run() {
      releaseTapValues();
      /* ========= Exit = FALSE  =========  */
     }
    };
    tapHandler.postDelayed(tapRunnable, milSecDealy);
   }
  }

  private void releaseTapValues() {
   /* Relase the value  */
   if (tapHandler != null) {
    tapHandler.removeCallbacks(tapRunnable);
    tapRunnable = null; /* release the object */
    mTapCount = 0; /* release the value */
   }
  }


  @Override
  protected void onDestroy() {
   super.onDestroy();
   releaseTapValues();
  }

Great hack by @strager. Implement it into jQuery like this:

jQuery.fn.wait = function (MiliSeconds) {
    $(this).animate({ opacity: '+=0' }, MiliSeconds);
    return this;
}

And then use it as:

$('.notice').fadeIn().wait(2000).fadeOut('slow');

Try the following

$path =  $MyInvocation.MyCommand.Definition 

This may not give you the actual path typed in but it will give you a valid path to the file.

Nowadays - using C++11 - you can use enum class for this:

enum class Color { RED, BLUE, WHITE };

AFAII this does exactly what you want.

create dynamic name directory for each user... use this code

***suppose email contain user mail address***

var filessystem = require('fs');
var dir = './public/uploads/'+email;

if (!filessystem.existsSync(dir)){
  filessystem.mkdirSync(dir);

}else
{
    console.log("Directory already exist");
}

SO @NotNull just is a tag...If you want to validate it, then you must use something like hibernate validator jsr 303

ValidatorFactory validatorFactory = Validation.buildDefaultValidatorFactory();
Validator validator = validatorFactory.getValidator();
 Set<ConstraintViolation<List<Searching>> violations = validator.validate(searchingList);

Found one solution for WIFI (works for Android 4.3, 4.4):

1. Connect to WIFI network (e.g. 'Alex')
2. Settings->WIFI
3. Long tap on connected network's name (e.g. on 'Alex')
4. Modify network config-> Show advanced options
5. Set proxy settings

var lastname = "Hi";

if(typeof lastname !== "undefined")
{
  alert("Hi. Variable is defined.");
} 

Personally, I'd go for: (y == 0).sum() and (y == 1).sum()

E.g.

import numpy as np
y = np.array([0, 0, 0, 1, 0, 1, 1, 0, 0, 0, 0, 1])
num_zeros = (y == 0).sum()
num_ones = (y == 1).sum()

My Dark Color scheme for QtCreator is at:

Hope it is useful for someone.

Even if I'm a bit late, I thought it would be interesting for future users to share some one-liners implementations I did using ES6.

One thing that I consider important depending on your environment or/and what you will do with with the data is to preserve the full byte value. For example, (5).toString(2) will give you 101, but the complete binary conversion is in reality 00000101, and that's why you might need to create a leftPad implementation to fill the string byte with leading zeros. But you may not need it at all, like other answers demonstrated.

If you run the below code snippet, you'll see the first output being the conversion of the abc string to a byte array and right after that the re-transformation of said array to it's corresponding string.

// For each byte in our array, retrieve the char code value of the binary value_x000D_
const binArrayToString = array => array.map(byte => String.fromCharCode(parseInt(byte, 2))).join('')_x000D_
_x000D_
// Basic left pad implementation to ensure string is on 8 bits_x000D_
const leftPad = str => str.length < 8 ? (Array(8).join('0') + str).slice(-8) : str_x000D_
_x000D_
// For each char of the string, get the int code and convert it to binary. Ensure 8 bits._x000D_
const stringToBinArray = str => str.split('').map(c => leftPad(c.charCodeAt().toString(2)))_x000D_
_x000D_
const array = stringToBinArray('abc')_x000D_
_x000D_
console.log(array)_x000D_
console.log(binArrayToString(array))

Roman's answer worked fine for me - or at least, it gave me what I was expecting. Opening the video in the phone's native application is exactly the same as what the iPhone does.

It's probably worth adjusting your viewpoint and expect video to be played fullscreen in its own application, and coding for that. It's frustrating that clicking the video isn't sufficient to get it playing in the same way as the iPhone does, but seeing as it only takes an onclick attribute to launch it, it's not the end of the world.

My advice, FWIW, is to use a poster image, and make it obvious that it will play the video. I'm working on a project at the moment that does precisely that, and the clients are happy with it - and also that they're getting the Android version of a web app for free, of course, because the contract was only for an iPhone web app.

Just for illustration, a working Android video tag is below. Nice and simple.

<video src="video/placeholder.m4v" poster="video/placeholder.jpg" onclick="this.play();"/>

2D scatter plot

Using the scatter method of the matplotlib.pyplot module should work (at least with matplotlib 1.2.1 with Python 2.7.5), as in the example code below. Also, if you are using scatter plots, use scatterpoints=1 rather than numpoints=1 in the legend call to have only one point for each legend entry.

In the code below I've used random values rather than plotting the same range over and over, making all the plots visible (i.e. not overlapping each other).

import matplotlib.pyplot as plt
from numpy.random import random

colors = ['b', 'c', 'y', 'm', 'r']

lo = plt.scatter(random(10), random(10), marker='x', color=colors[0])
ll = plt.scatter(random(10), random(10), marker='o', color=colors[0])
l  = plt.scatter(random(10), random(10), marker='o', color=colors[1])
a  = plt.scatter(random(10), random(10), marker='o', color=colors[2])
h  = plt.scatter(random(10), random(10), marker='o', color=colors[3])
hh = plt.scatter(random(10), random(10), marker='o', color=colors[4])
ho = plt.scatter(random(10), random(10), marker='x', color=colors[4])

plt.legend((lo, ll, l, a, h, hh, ho),
           ('Low Outlier', 'LoLo', 'Lo', 'Average', 'Hi', 'HiHi', 'High Outlier'),
           scatterpoints=1,
           loc='lower left',
           ncol=3,
           fontsize=8)

plt.show()

3D scatter plot

To plot a scatter in 3D, use the plot method, as the legend does not support Patch3DCollection as is returned by the scatter method of an Axes3D instance. To specify the markerstyle you can include this as a positional argument in the method call, as seen in the example below. Optionally one can include argument to both the linestyle and marker parameters.

import matplotlib.pyplot as plt
from numpy.random import random
from mpl_toolkits.mplot3d import Axes3D

colors=['b', 'c', 'y', 'm', 'r']

ax = plt.subplot(111, projection='3d')

ax.plot(random(10), random(10), random(10), 'x', color=colors[0], label='Low Outlier')
ax.plot(random(10), random(10), random(10), 'o', color=colors[0], label='LoLo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[1], label='Lo')
ax.plot(random(10), random(10), random(10), 'o', color=colors[2], label='Average')
ax.plot(random(10), random(10), random(10), 'o', color=colors[3], label='Hi')
ax.plot(random(10), random(10), random(10), 'o', color=colors[4], label='HiHi')
ax.plot(random(10), random(10), random(10), 'x', color=colors[4], label='High Outlier')

plt.legend(loc='upper left', numpoints=1, ncol=3, fontsize=8, bbox_to_anchor=(0, 0))

plt.show()

As your clock.js is in the root, put your code as this to call your javascript in the index.html found in the folders you mentioned.

<SCRIPT LANGUAGE="JavaScript" SRC="../clock.js"></SCRIPT>

This will call the clock.js which you put in the root of your web site.

To use in Eloquent. Add on top of your model

protected $table = 'table_name as alias'

//table_name should be exact as in your database

..then use in your query like

ModelName::query()->select(alias.id, alias.name)

Not very clear what your issue is, but it sounds like you want something like this:

    List<string> printer = new List<string>( new [] { "jupiter", "neptune", "pangea", "mercury", "sonic" } );

    if( printer.Exists( p => p.Equals( "jupiter" ) ) )
    {
        ...
    }

var array = searchTerms.split(",");

for (var i in array){
     alert(array[i]);
}

You can use the simple program StarUML. The trial version is unlimited and can do almost anything.

Onced installed you can use it to generate great number of uml digrams just by pasting the source code. Class diagram is just one type of it. (It understands not only Java language but C#, C++ and other)

P.S. The program is great for drawing architectural diagrams before you start to code the program.

Alternatively, you can also delete a Foreign Key Constraint from the SQL Server Management Studio itself. You can try it if the commands do not work.

1. Expand your database view.
2. Right Click on Table which has foreign key constraint. Choose Design. A tab with the information about table columns will open.
3. Right click on the column which has the foreign key reference. Or you can right click on any column. Choose Relationships.
4. A list of relationships will appear (if you have one) in a pop up window.
5. From there you can delete the foreign key constraint.

I hope that helps

You need to escape the dot if you want to split on a literal dot:

String extensionRemoved = filename.split("\\.")[0];

Otherwise you are splitting on the regex ., which means "any character".
Note the double backslash needed to create a single backslash in the regex.

You're getting an ArrayIndexOutOfBoundsException because your input string is just a dot, ie ".", which is an edge case that produces an empty array when split on dot; split(regex) removes all trailing blanks from the result, but since splitting a dot on a dot leaves only two blanks, after trailing blanks are removed you're left with an empty array.

To avoid getting an ArrayIndexOutOfBoundsException for this edge case, use the overloaded version of split(regex, limit), which has a second parameter that is the size limit for the resulting array. When limit is negative, the behaviour of removing trailing blanks from the resulting array is disabled:

".".split("\\.", -1) // returns an array of two blanks, ie ["", ""]

ie, when filename is just a dot ".", calling filename.split("\\.", -1)[0] will return a blank, but calling filename.split("\\.")[0] will throw an ArrayIndexOutOfBoundsException.

Please read and strongly consider my advice in the comments of your post. That being said, if you still have a good reason to do this, check out this list of crypto modules for Node. It has modules for dealing with both sha1 and base64.

Use stored procedures.

And even assuming you would want not to use stored procedures - there is at most 3 commands to be run, not 4. Second getting id is useless, as you can do "INSERT INTO ... RETURNING".

Seeing the answers I have nothing else to add but one more thing:

in your test.html file you have written

link rel="stylesheet" type="css/text" href="test.css"/

see where you have written

type="css/text"

there you need to change into

type="text/css"

so it will look like that

link rel="stylesheet" type="text/css" href="test.css"/

and in this case the CSS file will be linked to HTML file

BEGIN-END blocks are the building blocks of PL/SQL, and each PL/SQL unit is contained within at least one such block. Nesting BEGIN-END blocks within PL/SQL blocks is usually done to trap certain exceptions and handle that special exception and then raise unrelated exceptions. Nevertheless, in PL/SQL you (the client) must always issue a commit or rollback for the transaction.

If you wish to have atomic transactions within a PL/SQL containing transaction, you need to declare a PRAGMA AUTONOMOUS_TRANSACTION in the declaration block. This will ensure that any DML within that block can be committed or rolledback independently of the containing transaction.

However, you cannot declare this pragma for nested blocks. You can only declare this for:

• Top-level (not nested) anonymous PL/SQL blocks
• List item
• Local, standalone, and packaged functions and procedures
• Methods of a SQL object type
• Database triggers

Actually, DB::connection('name')->select(..) doesnt work for me, because 'name' has to be in double quotes: "name"

Still, the select query is executed on my default connection. Still trying to figure out, how to convince Laravel to work the way it is intended: change the connection.

Edit: I figured it out. After debugging Laravels DatabaseManager it turned out my database.php (config file) (inside $this->app) was wrong. In the section "connections" I had stuff like "database" with values of the one i copied it from. In clear terms, instead of

env('DB_DATABASE', 'name')

I needed to place something like

'myNewName'

since all connections were listed with the same values for the database, username, password, etc. which of course makes little sense if I want to access at least another database name

Therefore, every time I wanted to select something from another database I always ended up in my default database

                }).success( function(){  alert("This Function will execute after data table loaded");   });
            }

This is a C# UIView extension method that's based on @SwiftArchitect's code. When auto layout is involved and controls need to move depending on the label's text, this calling code uses the Superview of the label as the transition view instead of the label itself. I added a lambda expression for the action to make it more encapsulated.

public static void FadeTransition( this UIView AView, double ADuration, Action AAction )
{
  CATransition transition = new CATransition();

  transition.Duration = ADuration;
  transition.TimingFunction = CAMediaTimingFunction.FromName( CAMediaTimingFunction.Linear );
  transition.Type = CATransition.TransitionFade;

  AView.Layer.AddAnimation( transition, transition.Type );
  AAction();
}

Calling code:

  labelSuperview.FadeTransition( 0.5d, () =>
  {
    if ( condition )
      label.Text = "Value 1";
    else
      label.Text = "Value 2";
  } );

when bullet have to hide then use:

li { list-style: none;}

when bullet have to list show, then use:

li { list-style: initial;}

As you said GWT does not support reflection. You should use deferred binding instead of reflection, or third party library such as gwt-ent for reflection suppport at gwt layer.

I created a JsFiddle here based on the answer given by Zachary. It provides a more accessible user interface and also escapes double quotes within strings properly.

// is unconditionally "flooring division", e.g:

>>> 4.0//1.5
2.0

As you see, even though both operands are floats, // still floors -- so you always know securely what it's going to do.

Single / may or may not floor depending on Python release, future imports, and even flags on which Python's run, e.g.:

$ python2.6 -Qold -c 'print 2/3'
0
$ python2.6 -Qnew -c 'print 2/3'
0.666666666667

As you see, single / may floor, or it may return a float, based on completely non-local issues, up to and including the value of the -Q flag...;-).

So, if and when you know you want flooring, always use //, which guarantees it. If and when you know you don't want flooring, slap a float() around other operand and use /. Any other combination, and you're at the mercy of version, imports, and flags!-)

UPDATE tobeupdated
INNER JOIN original ON (tobeupdated.value = original.value)
SET tobeupdated.id = original.id

That should do it, and really its doing exactly what yours is. However, I prefer 'JOIN' syntax for joins rather than multiple 'WHERE' conditions, I think its easier to read

As for running slow, how large are the tables? You should have indexes on tobeupdated.value and original.value

EDIT: we can also simplify the query

UPDATE tobeupdated
INNER JOIN original USING (value)
SET tobeupdated.id = original.id

USING is shorthand when both tables of a join have an identical named key such as id. ie an equi-join - http://en.wikipedia.org/wiki/Join_(SQL)#Equi-join

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

You need to use the doubleValue() method to get the double value from a BigDecimal object.

BigDecimal bd; // the value you get
double d = bd.doubleValue(); // The double you want

I had through the same situation. I solved using two Promise.All().

I think was really good solution, so I published it on npm: https://www.npmjs.com/package/promise-foreach

I think your code will be something like this

var promiseForeach = require('promise-foreach')
var jsonItems = [];
promiseForeach.each(jsonItems,
    [function (jsonItems){
        return new Promise(function(resolve, reject){
            if(jsonItems.type === 'file'){
                jsonItems.getFile().then(function(file){ //or promise.all?
                    resolve(file.getSize())
                })
            }
        })
    }],
    function (result, current) {
        return {
            type: current.type,
            size: jsonItems.result[0]
        }
    },
    function (err, newList) {
        if (err) {
            console.error(err)
            return;
        }
        console.log('new jsonItems : ', newList)
    })

You are looking for str.rsplit(), with a limit:

print x.rsplit('-', 1)[0]

.rsplit() searches for the splitting string from the end of input string, and the second argument limits how many times it'll split to just once.

Another option is to use str.rpartition(), which will only ever split just once:

print x.rpartition('-')[0]

For splitting just once, str.rpartition() is the faster method as well; if you need to split more than once you can only use str.rsplit().

Demo:

>>> x = 'http://test.com/lalala-134'
>>> print x.rsplit('-', 1)[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rsplit('-', 1)[0]
'something-with-a-lot-of'

and the same with str.rpartition()

>>> print x.rpartition('-')[0]
http://test.com/lalala
>>> 'something-with-a-lot-of-dashes'.rpartition('-')[0]
'something-with-a-lot-of'

You can use java System.properties, for using them from eclipse you could:

1. Add -Dlabel="label_value" in the VM arguments of the test Run Configuration like this:

2. Then run the test:

   import org.junit.Test;
   import static org.junit.Assert.assertEquals;
   
   public class Main {
       @Test
       public void test(){
           System.out.println(System.getProperty("label"));
           assertEquals("label_value", System.getProperty("label"));
       }
   }
   

3. Finally it should pass the test and output this in the console:

   label_value
   

In this example you can identify different areas:

Short trick: after I only REMOVED SPACES from names of the folders, where the .jar file was, double-clicked worked and the file executed.

The answer by Tony Andrews is a decent one. But the real answer is that this has been a convention used by relational database community and is NOT a necessity. Maybe it is a good convention, maybe not.

Comparing anything to NULL results in UNKNOWN (3rd truth value). So as has been suggested with nulls all traditional wisdom concerning equality goes out the window. Well that's how it seems at first glance.

But I don't think this is necessarily so and even SQL databases don't think that NULL destroys all possibility for comparison.

Run in your database the query SELECT * FROM VALUES(NULL) UNION SELECT * FROM VALUES(NULL)

What you see is just one tuple with one attribute that has the value NULL. So the union recognized here the two NULL values as equal.

When comparing a composite key that has 3 components to a tuple with 3 attributes (1, 3, NULL) = (1, 3, NULL) <=> 1 = 1 AND 3 = 3 AND NULL = NULL The result of this is UNKNOWN.

But we could define a new kind of comparison operator eg. ==. X == Y <=> X = Y OR (X IS NULL AND Y IS NULL)

Having this kind of equality operator would make composite keys with null components or non-composite key with null value unproblematic.

You want to get an element from an empty array. That's why the Size: 0 from the exception

java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

So you cant do lstpp.get(0) until you fill the array.

It is now this For swift 3,

    let button = (sender as AnyObject)
    button.setTitle("Your text", for: .normal)

(The constant declaration of the variable is not necessary just make sure you use the sender from the button like this) :

    (sender as AnyObject).setTitle("Your text", for: .normal)

Remember this is used inside the IBAction of your button.

Make sure that You have created a correct package.You might get a chance to create folder instead of package

I would like to suggest you to use HighCharts. It's just awesome and easy to integrate.

Update for 2017

My original answer was written in 2009. While it still works, I'd like to update it for 2017. Browsers can still behave differently. I trust the jQuery team to do a great job at maintaining cross-browser consistency. However, it's not necessary to include the entire library. In the jQuery source, the relevant portion is found on line 37 of dimensions.js. Here it is extracted and modified to work standalone:

function getWidth() {_x000D_
  return Math.max(_x000D_
    document.body.scrollWidth,_x000D_
    document.documentElement.scrollWidth,_x000D_
    document.body.offsetWidth,_x000D_
    document.documentElement.offsetWidth,_x000D_
    document.documentElement.clientWidth_x000D_
  );_x000D_
}_x000D_
_x000D_
function getHeight() {_x000D_
  return Math.max(_x000D_
    document.body.scrollHeight,_x000D_
    document.documentElement.scrollHeight,_x000D_
    document.body.offsetHeight,_x000D_
    document.documentElement.offsetHeight,_x000D_
    document.documentElement.clientHeight_x000D_
  );_x000D_
}_x000D_
_x000D_
console.log('Width:  ' +  getWidth() );_x000D_
console.log('Height: ' + getHeight() );

Original Answer

Since all browsers behave differently, you'll need to test for values first, and then use the correct one. Here's a function that does this for you:

function getWidth() {
  if (self.innerWidth) {
    return self.innerWidth;
  }

  if (document.documentElement && document.documentElement.clientWidth) {
    return document.documentElement.clientWidth;
  }

  if (document.body) {
    return document.body.clientWidth;
  }
}

and similarly for height:

function getHeight() {
  if (self.innerHeight) {
    return self.innerHeight;
  }

  if (document.documentElement && document.documentElement.clientHeight) {
    return document.documentElement.clientHeight;
  }

  if (document.body) {
    return document.body.clientHeight;
  }
}

Call both of these in your scripts using getWidth() or getHeight(). If none of the browser's native properties are defined, it will return undefined.

There is no real ascii codes for these keys as such, you will need to check out the scan codes for these keys, known as Make and Break key codes as per helppc's information. The reason the codes sounds 'ascii' is because the key codes are handled by the old BIOS interrupt 0x16 and keyboard interrupt 0x9.

                 Normal Mode            Num lock on
                 Make    Break        Make          Break
Down arrow       E0 50   E0 D0     E0 2A E0 50   E0 D0 E0 AA
Left arrow       E0 4B   E0 CB     E0 2A E0 4B   E0 CB E0 AA
Right arrow      E0 4D   E0 CD     E0 2A E0 4D   E0 CD E0 AA
Up arrow         E0 48   E0 C8     E0 2A E0 48   E0 C8 E0 AA

Hence by looking at the codes following E0 for the Make key code, such as 0x50, 0x4B, 0x4D, 0x48 respectively, that is where the confusion arise from looking at key-codes and treating them as 'ascii'... the answer is don't as the platform varies, the OS varies, under Windows it would have virtual key code corresponding to those keys, not necessarily the same as the BIOS codes, VK_UP, VK_DOWN, VK_LEFT, VK_RIGHT.. this will be found in your C++'s header file windows.h, as I recall in the SDK's include folder.

Do not rely on the key-codes to have the same 'identical ascii' codes shown here as the Operating system will reprogram the entire BIOS code in whatever the OS sees fit, naturally that would be expected because since the BIOS code is 16bit, and the OS (nowadays are 32bit protected mode), of course those codes from the BIOS will no longer be valid.

Hence the original keyboard interrupt 0x9 and BIOS interrupt 0x16 would be wiped from the memory after the BIOS loads it and when the protected mode OS starts loading, it would overwrite that area of memory and replace it with their own 32 bit protected mode handlers to deal with those keyboard scan codes.

Here is a code sample from the old days of DOS programming, using Borland C v3:

#include <bios.h>
int getKey(void){
    int key, lo, hi;
    key = bioskey(0);
    lo = key & 0x00FF;
    hi = (key & 0xFF00) >> 8;
    return (lo == 0) ? hi + 256 : lo;
}

This routine actually, returned the codes for up, down is 328 and 336 respectively, (I do not have the code for left and right actually, this is in my old cook book!) The actual scancode is found in the lo variable. Keys other than the A-Z,0-9, had a scan code of 0 via the bioskey routine.... the reason 256 is added, because variable lo has code of 0 and the hi variable would have the scan code and adds 256 on to it in order not to confuse with the 'ascii' codes...

Your problem is that your insertAfter:

.insertAfter(".tr_clone")

inserts after every .tr_clone:

the matched set of elements will be inserted after the element(s) specified by this parameter.

You probably just want to use after on the row you're duplicating. And a little .find(':text').val('') will clear the cloned text inputs; something like this:

var $tr    = $(this).closest('.tr_clone');
var $clone = $tr.clone();
$clone.find(':text').val('');
$tr.after($clone);

Demo: http://jsfiddle.net/ambiguous/LAECx/ or for a modern jQuery: http://jsfiddle.net/ambiguous/LAECx/3274/

I'm not sure which input should end up with the focus so I've left that alone.

Don't need to quote css attributes and you should specify an unit. (You should use an external css file too..!)

Preamble

This is a very old question but it seems to still hit the nerve in 2020 as in 2012. I've checked all of the other answers and could not find a technique (note that this has its limitations, but all of the others are not applicable in every situation as well).

GIT + child process

If you are using GIT as your version control system, the problem of determining the project root can be reduced to (which I would consider the proper root of the project - after all, you would want your VCS to have the fullest visibility scope possible):

retrieve repository root path

Since you have to run a CLI command to do that, we will need to spawn a child process. Additionally, as project root is highly unlikely to change mid-runtime, we can use the synchronous version of the child_process module APIs at startup.

I found spawnSync() to be the most suitable for the job. As for the actual command to run, git worktree (with a --porcelain option for ease of parsing) is all we need to retrieve the absolute root path.

In the sample, I opted to return an array of paths because there might be more than one worktree (although they are likely to have common paths) just to be sure. Note that as we utilize a CLI command, shell option should be set to true (security shouldn't be an issue as there is no untrusted input).

Approach comparison and fallbacks

Understanding that a situation where VCS can be inaccessible is possible, I've included a couple of fallbacks after analyzing docs and other answers. To sum up, the solutions proposed boil down to (excluding third-party modules & package-specific):

| Solution                 | Advantage               | Main Problem                     |
| ------------------------ | ----------------------- | -------------------------------- |
| `__filename`             | points to module file   | relative to module               |
| `__dirname`              | points to module dir    | same as `__filename`             |
| `node_modules` tree walk | nearly guaranteed root  | complex tree walking if nested   |
| `path.resolve(".")`      | root if CWD is root     | same as `process.cwd()`          |
| `process.argv[1]`        | same as `__filename`    | same as `__filename`             |
| `process.env.INIT_CWD`   | points to `npm run` dir | requires `npm` && CLI launch     |
| `process.env.PWD`        | points to current dir   | relative to (is the) launch dir  |
| `process.cwd()`          | same as `env.PWD`       | `process.chdir(path)` at runtime |
| `require.main.filename`  | root if `=== module`    | fails on `require`d modules      |

From the comparison table above, the most universal are two approaches:

• require.main.filename as an easy way to get root if require.main === module is met
• node_modules tree walk proposed recently uses another assumption:

if the directory of the module has node_modules dir inside, it is likely to be the root

For the main app, it will get the app root and for the module - its project root.

Fallback 1. Tree walk

My implementation uses a more lax approach by stopping once a target directory is found as for a given module its root is its project root. One can chain the calls or extend it to make search depth configurable:

/**
 * @summary gets root by walking up node_modules
 * @param {import("fs")} fs
 * @param {import("path")} pt
 */
const getRootFromNodeModules = (fs, pt) =>

    /**
     * @param {string} [startPath]
     * @returns {string[]}
     */
    (startPath = __dirname) => {

        //avoid loop if reached root path
        if (startPath === pt.parse(startPath).root) {
            return [startPath];
        }

        const isRoot = fs.existsSync(pt.join(startPath, "node_modules"));

        if (isRoot) {
            return [startPath];
        }

        return getRootFromNodeModules(fs, pt)(pt.dirname(startPath));
    };

Fallback 2. Main module

The second implementation is trivial

/**
 * @summary gets app entry point if run directly
 * @param {import("path")} pt
 */
const getAppEntryPoint = (pt) =>

    /**
     * @returns {string[]}
     */
    () => {

        const { main } = require;

        const { filename } = main;

        return main === module ?
            [pt.parse(filename).dir] :
            [];
    };

Implementation

I would suggest use the tree walker as fallback because it is more versatile:

const { spawnSync } = require("child_process");
const pt = require('path');
const fs = require("fs");

/**
 * @summary returns worktree root path(s)
 * @param {function : string[] } [fallback]
 * @returns {string[]}
 */
const getProjectRoot = (fallback) => {

    const { error, stdout } = spawnSync(
        `git worktree list --porcelain`,
        {
            encoding: "utf8",
            shell: true
        }
    );

    if (!stdout) {
        console.warn(`Could not use GIT to find root:\n\n${error}`);
        return fallback ? fallback() : [];
    }

    return stdout
        .split("\n")
        .map(line => {
            const [key, value] = line.split(/\s+/) || [];
            return key === "worktree" ? value : "";
        })
        .filter(Boolean);
};

Disadvantages

The most obvious is having GIT installed and initialized which might be undesirable / implausible (side note: having GIT installed on production servers is not uncommon, nor is it unsafe, though). Can be mediated by fallbacks as described above.

Notes

1. A couple of ideas for further extension of approach 1:

• introduce config as a function parameter
• export the function to make it a module
• check if GIT is installed and / or initialized

Here is my modification of @rashy above. The script does the following:

• it verifies you have access, if not, requests it
• allows you to enter in multiple hosts in a list
• loops through the list
• It finds the line containing the the domain name and removes it, then re-adds it (incase the ip has changed since the last time the script was run).
• if the domain isn't there, it just adds it.

This is the script:

updated to follow slowly

http://jsfiddle.net/BfLAh/3/

for the orientation , you need to get the current css left and css top and compare with event.pageX and event.pageY , then set the image orientation with

-webkit-transform: rotate(-90deg); 
-moz-transform: rotate(-90deg); 

for the speed , you can set the jquery .animation duration to certain amount.

To calculate MD5 hash of CLOB content field with my desired encoding without implicitly recoding content to AL32UTF8, I've used this code:

create or replace function clob2blob(AClob CLOB) return BLOB is
  Result BLOB;
  o1 integer;
  o2 integer;
  c integer;
  w integer;
begin
  o1 := 1;
  o2 := 1;
  c := 0;
  w := 0;
  DBMS_LOB.CreateTemporary(Result, true);
  DBMS_LOB.ConvertToBlob(Result, AClob, length(AClob), o1, o2, 0, c, w);
  return(Result);
end clob2blob;
/

update my_table t set t.hash = (rawtohex(DBMS_CRYPTO.Hash(clob2blob(t.content),2)));

The accepted answer correctly describes how the list should be declared and is highly recommended for most scenarios.

But I came across a different scenario, which also covers the question asked. What if you have to use an existing object list, like ViewData["htmlAttributes"] in MVC? How can you access its properties (they are usually created via new { @style="width: 100px", ... })?

For this slightly different scenario I want to share with you what I found out. In the solutions below, I am assuming the following declaration for nodes:

List<object> nodes = new List<object>();

nodes.Add(
new
{
    Checked = false,
    depth = 1,
    id = "div_1" 
});

1. Solution with dynamic

In C# 4.0 and higher versions, you can simply cast to dynamic and write:

if (nodes.Any(n => ((dynamic)n).Checked == false))
    Console.WriteLine("found a  not checked  element!");

Note: This is using late binding, which means it will recognize only at runtime if the object doesn't have a Checked property and throws a RuntimeBinderException in this case - so if you try to use a non-existing Checked2 property you would get the following message at runtime: "'<>f__AnonymousType0<bool,int,string>' does not contain a definition for 'Checked2'".

2. Solution with reflection

The solution with reflection works both with old and new C# compiler versions. For old C# versions please regard the hint at the end of this answer.

Background

As a starting point, I found a good answer here. The idea is to convert the anonymous data type into a dictionary by using reflection. The dictionary makes it easy to access the properties, since their names are stored as keys (you can access them like myDict["myProperty"]).

Inspired by the code in the link above, I created an extension class providing GetProp, UnanonymizeProperties and UnanonymizeListItems as extension methods, which simplify access to anonymous properties. With this class you can simply do the query as follows:

if (nodes.UnanonymizeListItems().Any(n => (bool)n["Checked"] == false))
{
    Console.WriteLine("found a  not checked  element!");
}

or you can use the expression nodes.UnanonymizeListItems(x => (bool)x["Checked"] == false).Any() as if condition, which filters implicitly and then checks if there are any elements returned.

To get the first object containing "Checked" property and return its property "depth", you can use:

var depth = nodes.UnanonymizeListItems()
             ?.FirstOrDefault(n => n.Contains("Checked")).GetProp("depth");

or shorter: nodes.UnanonymizeListItems()?.FirstOrDefault(n => n.Contains("Checked"))?["depth"];

Note: If you have a list of objects which don't necessarily contain all properties (for example, some do not contain the "Checked" property), and you still want to build up a query based on "Checked" values, you can do this:

if (nodes.UnanonymizeListItems(x => { var y = ((bool?)x.GetProp("Checked", true)); 
                                      return y.HasValue && y.Value == false;}).Any())
{
    Console.WriteLine("found a  not checked   element!");
}

This prevents, that a KeyNotFoundException occurs if the "Checked" property does not exist.

The class below contains the following extension methods:

• UnanonymizeProperties: Is used to de-anonymize the properties contained in an object. This method uses reflection. It converts the object into a dictionary containing the properties and its values.
• UnanonymizeListItems: Is used to convert a list of objects into a list of dictionaries containing the properties. It may optionally contain a lambda expression to filter beforehand.
• GetProp: Is used to return a single value matching the given property name. Allows to treat not-existing properties as null values (true) rather than as KeyNotFoundException (false)

For the examples above, all that is required is that you add the extension class below:

public static class AnonymousTypeExtensions
{
    // makes properties of object accessible 
    public static IDictionary UnanonymizeProperties(this object obj)
    {
        Type type = obj?.GetType();
        var properties = type?.GetProperties()
               ?.Select(n => n.Name)
               ?.ToDictionary(k => k, k => type.GetProperty(k).GetValue(obj, null));
        return properties;
    }
    
    // converts object list into list of properties that meet the filterCriteria
    public static List<IDictionary> UnanonymizeListItems(this List<object> objectList, 
                    Func<IDictionary<string, object>, bool> filterCriteria=default)
    {
        var accessibleList = new List<IDictionary>();
        foreach (object obj in objectList)
        {
            var props = obj.UnanonymizeProperties();
            if (filterCriteria == default
               || filterCriteria((IDictionary<string, object>)props) == true)
            { accessibleList.Add(props); }
        }
        return accessibleList;
    }

    // returns specific property, i.e. obj.GetProp(propertyName)
    // requires prior usage of AccessListItems and selection of one element, because
    // object needs to be a IDictionary<string, object>
    public static object GetProp(this object obj, string propertyName, 
                                 bool treatNotFoundAsNull = false)
    {
        try 
        {
            return ((System.Collections.Generic.IDictionary<string, object>)obj)
                   ?[propertyName];
        }
        catch (KeyNotFoundException)
        {
            if (treatNotFoundAsNull) return default(object); else throw;
        }
    }
}

Hint: The code above is using the null-conditional operators, available since C# version 6.0 - if you're working with older C# compilers (e.g. C# 3.0), simply replace ?. by . and ?[ by [ everywhere (and do the null-handling traditionally by using if statements or catch NullReferenceExceptions), e.g.

var depth = nodes.UnanonymizeListItems()
            .FirstOrDefault(n => n.Contains("Checked"))["depth"];

As you can see, the null-handling without the null-conditional operators would be cumbersome here, because everywhere you removed them you have to add a null check - or use catch statements where it is not so easy to find the root cause of the exception resulting in much more - and hard to read - code.

If you're not forced to use an older C# compiler, keep it as is, because using null-conditionals makes null handling much easier.

Note: Like the other solution with dynamic, this solution is also using late binding, but in this case you're not getting an exception - it will simply not find the element if you're referring to a non-existing property, as long as you keep the null-conditional operators.

What might be useful for some applications is that the property is referred to via a string in solution 2, hence it can be parameterized.

This was not as straightforward as I would have hoped. You need to use enumerate to keep track of how many columns you have. Then use that counter to look up the name of the column. The accepted answer does not show you how to access the column names dynamically.

for row in df.itertuples(index=False, name=None):
    for k,v in enumerate(row):
        print("column: {0}".format(df.columns.values[k]))
        print("value: {0}".format(v)

The options for popen can be used in call

So...

subprocess.call(["/home/myuser/run.sh", "/tmp/ad_xml",  "/tmp/video_xml"], stdout=myoutput)

Then you can do what you want with myoutput (which would need to be a file btw).

Also, you can do something closer to a piped output like this.

dmesg | grep hda

would be:

p1 = Popen(["dmesg"], stdout=PIPE)
p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
output = p2.communicate()[0]

There's plenty of lovely, useful info on the python manual page.

A possible soluttion that requires tweaking, but is very flexible is to use one of \big, \Big, \bigg,\Bigg in front of your division sign - these will make it progressively larger. For your formula, I think

  $\frac{a_1}{a_2} \Big/ \frac{b_1}{b_2}$

looks nicer than \middle\ which is automatically sized and IMHO is a bit too large.

It happens if the connection was open for quite sometime but no action was done in the MySQL server. In that case, connection timeout occurs with the error "MySQL server has gone away". The answers above may work and may not work. Even the accepted answer did not work for me. So I tried a trick and it worked fine for me. Logically, in order to avoid this error, we have to keep the MySQL connection running or in short, keep it alive. Assume that we are trying to Bulk insert 250k records. Generally it takes time to create parse data from somewhere and make Bulk query and then insert. In this scenario, most of us use a loop to create the SQL string. So let's count the iteration number and make a dummy database call after a certain iteration. It will keep the connection alive.

for(int i = 0, size = somedatalist.length; i < size; ++i){

     // build the Bulk insert query string

     if((i%10000)==0){
         // make a dummy call like `SELECT * FROM log LIMIT 1`
         // it will keep the connection alive
     }
}
// Execute bulk insert

I think this should work:

#include <time.h>

clock_t start = clock(), diff;
ProcessIntenseFunction();
diff = clock() - start;

int msec = diff * 1000 / CLOCKS_PER_SEC;
printf("Time taken %d seconds %d milliseconds", msec/1000, msec%1000);

If you don't want to convert.Just use;

 bool _status = status == "1" ? true : false;

Perhaps you will return the values as you want.

Hello year 2010 question.

The OP.'s requirement is preserve keys (keep keys) and not overlap (I think overwrite). In some case such as numeric keys it is possible but if string keys it seems to be not possible.

If you use array_merge() the numeric keys will always re-index or renumbered.
If you use array_replace(), array_replace_recursive() it will be overlap or overwrite from the right to the left. The value with the same key on first array will be replaced with second array.
If you use $array1 + $array2 as the comment was mentioned, if the keys are same then it will keep the value from first array but drop the second array.

Custom function.

Here is my function that I just wrote to work on the same requirements. You are free to use for any purpose.

/**
 * Array custom merge. Preserve indexed array key (numbers) but overwrite string key (same as PHP's `array_merge()` function).
 * 
 * If the another array key is string, it will be overwrite the first array.<br>
 * If the another array key is integer, it will be add to first array depend on duplicated key or not. 
 * If it is not duplicate key with the first, the key will be preserve and add to the first array.
 * If it is duplicated then it will be re-index the number append to the first array.
 *
 * @param array $array1 The first array is main array.
 * @param array ...$arrays The another arrays to merge with the first.
 * @return array Return merged array.

                // item on the right will always overwrite on the left.
                $array1[$key] = $item;
            } elseif (is_int($key) && !array_key_exists($key, $array1)) {
                // if key is number. this should be indexed array.
                // and if array 1 is not already has this key.
                // add this array with the key preserved to array 1.
                $array1[$key] = $item;

Doesn't your access to SVN work just like a Web service? When I access the top directory of my SVN server, I get a page that's essentially a Table Of Contents of the whole works. It's an Unordered List that I can simply scan through.

EDIT: Here's how I would do it from the command line:

wget http://user:password@svn-url/ -O - | grep \<li\>

I had the same issue, luckily I found the below code

@Html.CheckBoxFor(model => model.As, htmlAttributes: new { @checked = true} )

In my particular case, I am using Babylon.js to create a 3D scene and my whole page consists of one full screen canvas. The 3D engine has its own zooming functionality but on iOS the pinch-to-zoom interferes with that. I updated the the @Joseph answer to overcome my problem. To disable it, I figured out that I need to pass the {passive: false} as an option to the event listener. The following code works for me:

window.addEventListener(
    "touchmove",
    function(event) {
        if (event.scale !== 1) {
            event.preventDefault();
        }
    },
    { passive: false }
);

Or you can style it with pixels.

 .big-checkbox {width: 30px; height: 30px;}

Jquery later allowed you to to find the parents with the .parents() method.

Hence I recommend using:

var $div = $('#divid').parents('div[class^="div-a"]');

This gives all parent nodes matching the selector. To get the first parent matching the selector use:

var $div = $('#divid').parents('div[class^="div-a"]').eq(0);

Check out my highly simplified Echo example: It is designed to use basic HTTP communication, but it can easily be modified to use named pipes by editing the app.config files for the client and server. Make the following changes:

Edit the server's app.config file, removing or commenting out the http baseAddress entry and adding a new baseAddress entry for the named pipe (called net.pipe). Also, if you don't intend on using HTTP for a communication protocol, make sure the serviceMetadata and serviceDebug is either commented out or deleted:

<configuration>
    <system.serviceModel>
        <services>
            <service name="com.aschneider.examples.wcf.services.EchoService">
                <host>
                    <baseAddresses>
                        <add baseAddress="net.pipe://localhost/EchoService"/>
                    </baseAddresses>
                </host>
            </service>
        </services>
        <behaviors>
            <serviceBehaviors></serviceBehaviors>
        </behaviors>
    </system.serviceModel>
</configuration>

Edit the client's app.config file so that the basicHttpBinding is either commented out or deleted and a netNamedPipeBinding entry is added. You will also need to change the endpoint entry to use the pipe:

<configuration>
    <system.serviceModel>
        <bindings>
            <netNamedPipeBinding>
                <binding name="NetNamedPipeBinding_IEchoService"/>
            </netNamedPipeBinding>
        </bindings>
        <client>
            <endpoint address              = "net.pipe://localhost/EchoService"
                      binding              = "netNamedPipeBinding"
                      bindingConfiguration = "NetNamedPipeBinding_IEchoService"
                      contract             = "EchoServiceReference.IEchoService"
                      name                 = "NetNamedPipeBinding_IEchoService"/>
        </client>

The above example will only run with named pipes, but nothing is stopping you from using multiple protocols to run your service. AFAIK, you should be able to have a server run a service using both named pipes and HTTP (as well as other protocols).

Also, the binding in the client's app.config file is highly simplified. There are many different parameters you can adjust, aside from just specifying the baseAddress...

The solution I ended up choosing was MahApps.Metro (github), which (after using it on two pieces of software now) I consider an excellent UI kit (credit to Oliver Vogel for the suggestion).

It skins the application with very little effort required, and has adaptations of the standard Windows 8 controls. It's very robust.

A version is available on Nuget:

You can install MahApps.Metro via Nuget using the GUI (right click on your project, Manage Nuget References, search for ‘MahApps.Metro’) or via the console:

PM> Install-Package MahApps.Metro

It's also free -- even for commercial use.

Update 10-29-2013:

I discovered that the Github version of MahApps.Metro is packed with controls and styles that aren't available in the current nuget version, including:

Datagrids:

Clean Window:

Flyouts:

Tiles:

The github repository is very active with quite a bit of user contributions. I recommend checking it out.

There isn't any need for fake <td>s. Make use of border-spacing instead. Apply it like this:

HTML:

<table>
  <tr>
    <td>First Column</td>
    <td>Second Column</td>
    <td>Third Column</td>
  </tr>
</table>

CSS:

table {
  border-collapse: separate;
  border-spacing: 50px 0;
}

td {
  padding: 10px 0;
}

See it in action.

This is my code .This works for me

componentDidMount(){
        axios.get('http://localhost:5000/supplier').then(
            response => {
                console.log(response)
                this.setState({suppliers:response.data.data})
            }
        )
        .catch(error => {
            console.log(error)
        })
        
    }

componentDidUpdate(){
        this.componentDidMount();
}

window.location.reload(); I think this thing is not good for react js

As posted in my earlier answer

Use below code :

TelephonyManager tMgr = (TelephonyManager)mAppContext.getSystemService(Context.TELEPHONY_SERVICE);
String mPhoneNumber = tMgr.getLine1Number();

In AndroidManifest.xml, give the following permission:

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

But remember, this code does not always work, since Cell phone number is dependent on the SIM Card and the Network operator / Cell phone carrier.

Also, try checking in Phone--> Settings --> About --> Phone Identity, If you are able to view the Number there, the probability of getting the phone number from above code is higher. If you are not able to view the phone number in the settings, then you won't be able to get via this code!

Suggested Workaround:

1. Get the user's phone number as manual input from the user.
2. Send a code to the user's mobile number via SMS.
3. Ask user to enter the code to confirm the phone number.
4. Save the number in sharedpreference.

Do the above 4 steps as one time activity during the app's first launch. Later on, whenever phone number is required, use the value available in shared preference.

JSX Comments Syntax: You can use

{/** 
  your comment 
  in multiple lines
  for documentation 
**/} 

or

{/* 
  your comment 
  in multiple lines
*/} 

for multiple lines comment. And also,

{ 
  //your comment 
} 

for single line comment.

Note: The syntax:

{ //your comment } 

doesn't work. You need to type braces in new lines.

Curly braces are used to distinguish between JSX and JavaScript in a React component. Inside curly braces, we use JavaScript comment syntax.

}

If the files you are sorting can be modified or updated at the same time the sort is being performed:

Java 8+

private static List<Path> listFilesOldestFirst(final String directoryPath) throws IOException {
    try (final Stream<Path> fileStream = Files.list(Paths.get(directoryPath))) {
        return fileStream
            .map(Path::toFile)
            .collect(Collectors.toMap(Function.identity(), File::lastModified))
            .entrySet()
            .stream()
            .sorted(Map.Entry.comparingByValue())
//            .sorted(Collections.reverseOrder(Map.Entry.comparingByValue()))  // replace the previous line with this line if you would prefer files listed newest first
            .map(Map.Entry::getKey)
            .map(File::toPath)  // remove this line if you would rather work with a List<File> instead of List<Path>
            .collect(Collectors.toList());
    }
}

Java 7

private static List<File> listFilesOldestFirst(final String directoryPath) throws IOException {
    final List<File> files = Arrays.asList(new File(directoryPath).listFiles());
    final Map<File, Long> constantLastModifiedTimes = new HashMap<File,Long>();
    for (final File f : files) {
        constantLastModifiedTimes.put(f, f.lastModified());
    }
    Collections.sort(files, new Comparator<File>() {
        @Override
        public int compare(final File f1, final File f2) {
            return constantLastModifiedTimes.get(f1).compareTo(constantLastModifiedTimes.get(f2));
        }
    });
    return files;
}

Both of these solutions create a temporary map data structure to save off a constant last modified time for each file in the directory. The reason we need to do this is that if your files are being updated or modified while your sort is being performed then your comparator will be violating the transitivity requirement of the comparator interface's general contract because the last modified times may be changing during the comparison.

If, on the other hand, you know the files will not be updated or modified during your sort, you can get away with pretty much any other answer submitted to this question, of which I'm partial to:

Java 8+ (No concurrent modifications during sort)

private static List<Path> listFilesOldestFirst(final String directoryPath) throws IOException {
    try (final Stream<Path> fileStream = Files.list(Paths.get(directoryPath))) {
        return fileStream
            .map(Path::toFile)
            .sorted(Comparator.comparing(File::lastModified))
            .map(File::toPath)  // remove this line if you would rather work with a List<File> instead of List<Path>
            .collect(Collectors.toList());
    }
}

Note: I know you can avoid the translation to and from File objects in the above example by using Files::getLastModifiedTime api in the sorted stream operation, however, then you need to deal with checked IO exceptions inside your lambda which is always a pain. I'd say if performance is critical enough that the translation is unacceptable then I'd either deal with the checked IOException in the lambda by propagating it as an UncheckedIOException or I'd forego the Files api altogether and deal only with File objects:

final List<File> sorted = Arrays.asList(new File(directoryPathString).listFiles());
sorted.sort(Comparator.comparing(File::lastModified));

You need to put that code into the constructor of your class:

private Reminders reminder = new Reminders();
private dynamic defaultReminder;

public YourClass()
{
    defaultReminder = reminder.TimeSpanText[TimeSpan.FromMinutes(15)];
}

The reason is that you can't use one instance variable to initialize another one using a field initializer.

According to the Apache Tomcat docs, you can change the application by creating a ROOT.xml file. See this for more info:

http://tomcat.apache.org/tomcat-6.0-doc/config/context.html

"The default web application may be defined by using a file called ROOT.xml."

If your input is search, you also can use on 'search' event. Example

<input type="search" placeholder="Search" id="searchTextBox">

.

$("#searchPostTextBox").on('search', function () {
    alert("search value: "+$(this).val());
});

I wold create a control named for example InfoProgresBar, that provide this functionality with a label or two (Main Job, Current Job) and ProgressBar and use it instead of that ProgressBar.

Access 2007 can lose the CurrentDb: see http://support.microsoft.com/kb/167173, so in the event of getting "Object Invalid or no longer set" with the examples, use:

Dim db as Database
Dim rs As DAO.Recordset
Set db = CurrentDB
Set rs = db.OpenRecordset("SELECT * FROM myTable")

You can make use of the defaultSelected property of an option element:

Contains the initial value of the selected HTML attribute, indicating whether the option is selected by default or not.

So, the DOM interface already keeps track which option was selected initially.

$("#reset").on("click", function () {
    $('#my_select option').prop('selected', function() {
        return this.defaultSelected;
    });
});

DEMO

This would even work for multi-select elements.

If you don't want to iterate over all options, but "break" after you found the originally selected one, you can use .each instead:

$('#my_select option').each(function () {
    if (this.defaultSelected) {
        this.selected = true;
        return false;
    }
});

Without jQuery:

var options = document.querySelectorAll('#my_select option');
for (var i = 0, l = options.length; i < l; i++) {
    options[i].selected = options[i].defaultSelected;
}

void show() throws Exception
{
    throw new Exception("my.own.Exception");
}

As there is checked exception in show() method , which is not being handled in that method so we use throws keyword for propagating the Exception.

void show2() throws Exception //Why throws is necessary here ?
{
show();
}

Since you are using the show() method in show2() method and you have propagated the exception atleast you should be handling here. If you are not handling the Exception here , then you are using throws keyword. So that is the reason for using throws keyword at the method signature.

FUNCTIONAL REQUIREMENTS the activities the system must perform

• business uses functions the users carry out
• use cases example if you are developing a payroll system required functions
• generate electronic fund transfers
• calculation commission amounts
• calculate payroll taxes
• report tax deduction to the IRS

ALTER TABLE public.contract_termination_requests
ALTER COLUMN management_company_id DROP NOT NULL;

An updated version of Rails/ActiveRecord may support this syntax natively. It would look similar to:

Foo.where(foo: 'bar').or.where(bar: 'bar')

As noted in this pull request https://github.com/rails/rails/pull/9052

For now, simply sticking with the following works great:

Foo.where('foo= ? OR bar= ?', 'bar', 'bar')

Update: According to https://github.com/rails/rails/pull/16052 the or feature will be available in Rails 5

Update: Feature has been merged to Rails 5 branch

Make a reverse dictionary

reverse_dictionary = {v:k for k,v in dictionary.items()} 

If you have a lot of reverse lookups to do

I'd do it like this:

colnames=['TIME', 'X', 'Y', 'Z'] 
user1 = pd.read_csv('dataset/1.csv', names=colnames, header=None)

If you want to check the number of insertions, deletions & commits, between two branches or commits.

using commit id's:

git log <commit-id>..<commit-id> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'

using branches:

git log <parent-branch>..<child-branch> --numstat --pretty="%H" --author="<author-name>" | awk 'NF==3 {added+=$1; deleted+=$2} NF==1 {commit++} END {printf("total lines added: +%d\ntotal lines deleted: -%d\ntotal commits: %d\n", added, deleted, commit)}'

I have simply replaced the "\n" with "<br>" tag. Worked fine. It seems TCPDF render the text as HTML

$strText = str_replace("\n","<br>",$strText);
$pdf->MultiCell($width, $height,$strText, 0, 'J', 0, 1, '', '', true, null, true);

You can use the BigInteger class for integers and BigDecimal for numbers with decimal digits. Both classes are defined in java.math package.

Example:

BigInteger reallyBig = new BigInteger("1234567890123456890");
BigInteger notSoBig = new BigInteger("2743561234");
reallyBig = reallyBig.add(notSoBig);

The reason for using POST when making changes to data:

• A web accelerator like Google Web Accelerator will click all (GET) links on a page and cache them. This is very bad if the links make changes to things.
• A browser caches GET requests so even if the user clicks the link it may not send a request to the server to execute the change.
• To protect your site/application against CSRF you must use POST. To completely secure your app you must then also generate a unique identifier on the server and send that along in the request.

Also, don't put sensitive information in the query string (only option with GET) because it shows up in the address bar, bookmarks and server logs.

Hopefully this explains why people say POST is 'secure'. If you are transmitting sensitive data you must use SSL.

I found the answer :

{% for key,value in array_path %}
    Key : {{ key }}
    Value : {{ value }}
{% endfor %}

To run an individual test:

npm test -t ValidationUtil # `ValidationUtil` is my module `ValidationUtil.spec.js`

-t - after it, put a regular expression containing the test name.

To set headers in an Axios POST request, pass the third object to the axios.post() call.

const token = '..your token..'

axios.post(url, {
  //...data
}, {
  headers: {
    'Authorization': `Basic ${token}` 
  }
})

To set headers in an Axios GET request, pass a second object to the axios.get() call.

const token = '..your token..' 

axios.get(url, {
  headers: {
    'Authorization': `Basic ${token}`
  }
})

On Windows 8.1 I had to run cmd.exe as administrator (even though I was logged in as admin). Otherwise I got an error when trying to execute: httpd.exe -k uninstall

If you want to trim all spaces, only in lines that have a comma, and use awk, then the following will work for you:

awk -F, '/,/{gsub(/ /, "", $0); print} ' input.txt

If you only want to remove spaces in the second column, change the expression to

awk -F, '/,/{gsub(/ /, "", $2); print$1","$2} ' input.txt

Note that gsub substitutes the character in // with the second expression, in the variable that is the third parameter - and does so in-place - in other words, when it's done, the $0 (or $2) has been modified.

Full explanation:

-F,            use comma as field separator 
               (so the thing before the first comma is $1, etc)
/,/            operate only on lines with a comma 
               (this means empty lines are skipped)
gsub(a,b,c)    match the regular expression a, replace it with b, 
               and do all this with the contents of c
print$1","$2   print the contents of field 1, a comma, then field 2
input.txt      use input.txt as the source of lines to process

EDIT I want to point out that @BMW's solution is better, as it actually trims only leading and trailing spaces with two successive gsub commands. Whilst giving credit I will give an explanation of how it works.

gsub(/^[ \t]+/,"",$2);    - starting at the beginning (^) replace all (+ = zero or more, greedy)
                             consecutive tabs and spaces with an empty string
gsub(/[ \t]+$/,"",$2)}    - do the same, but now for all space up to the end of string ($)
1                         - ="true". Shorthand for "use default action", which is print $0
                          - that is, print the entire (modified) line

Here is my code.

import java.util.Date;

// to calculate difference between two days
public class DateDifference {

// to calculate difference between two dates in milliseconds
public long getDateDiffInMsec(Date da, Date db) {
    long diffMSec = 0;
    diffMSec = db.getTime() - da.getTime();
    return diffMSec;
}

// to convert Milliseconds into DD HH:MM:SS format.
public String getDateFromMsec(long diffMSec) {
    int left = 0;
    int ss = 0;
    int mm = 0;
    int hh = 0;
    int dd = 0;
    left = (int) (diffMSec / 1000);
    ss = left % 60;
    left = (int) left / 60;
    if (left > 0) {
        mm = left % 60;
        left = (int) left / 60;
        if (left > 0) {
            hh = left % 24;
            left = (int) left / 24;
            if (left > 0) {
                dd = left;
            }
        }
    }
    String diff = Integer.toString(dd) + " " + Integer.toString(hh) + ":"
            + Integer.toString(mm) + ":" + Integer.toString(ss);
    return diff;

}
}

simple query would be, just set a variable to some number you want. then update the column you need by incrementing 1 from that number. for all the rows it'll update each row id by incrementing 1

I have a similar (but more complex scenario). I have a dialog, which contains a ViewPager.
One of the child pages is short, with a static height.
Another child page should always be as tall as possible.
Another child page contains a ScrollView, and the page (and thus the entire dialog) should WRAP_CONTENT if the ScrollView contents don't need the full height available to the dialog.

None of the existing answers worked completely for this specific scenario. Hold on- it's a bumpy ride.

void setupView() {
    final ViewPager.SimpleOnPageChangeListener pageChangeListener = new ViewPager.SimpleOnPageChangeListener() {
        @Override
        public void onPageSelected(int position) {

Much thanks to @Raanan for the code to measure views and measure the decor height. I ran into problems with his library- the animation stuttered, and I think my ScrollView wouldn't scroll when the height of the dialog was short enough to require it.

A collections.deque is optimized for pulling and pushing on both ends. They even have a dedicated rotate() method.

from collections import deque
items = deque([1, 2])
items.append(3)        # deque == [1, 2, 3]
items.rotate(1)        # The deque is now: [3, 1, 2]
items.rotate(-1)       # Returns deque to original state: [1, 2, 3]
item = items.popleft() # deque == [2, 3]

Flex Solution

It is perfectly fine if you want to go with the display: table-cell solution. But instead of hacking it out, we have a better way to accomplish the same using display: flex;. flex is something which has a decent support.

.wrap {_x000D_
  height: 200px;_x000D_
  width: 200px;_x000D_
  border: 1px solid #aaa;_x000D_
  margin: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
.wrap span {_x000D_
  align-self: flex-end;_x000D_
}

<div class="wrap">_x000D_
  <span>Align me to the bottom</span>_x000D_
</div>

In the above example, we first set the parent element to display: flex; and later, we use align-self to flex-end. This helps you push the item to the end of the flex parent.

Old Solution (Valid if you are not willing to use flex)

If you want to align the text to the bottom, you don't have to write so many properties for that, using display: table-cell; with vertical-align: bottom; is enough

div {_x000D_
  display: table-cell;_x000D_
  vertical-align: bottom;_x000D_
  border: 1px solid #f00;_x000D_
  height: 100px;_x000D_
  width: 100px;_x000D_
}

<div>Hello</div>

NORMALIZE this.WindowState = FormWindowState.Normal;

this.WindowState = FormWindowState.Minimized;

You can use Joda time library for Java. It would be much easier to calculate time-diff between dates with it.

Sample snippet for time-diff:

Days d = Days.daysBetween(startDate, endDate);
int days = d.getDays();

I know it's not pretty but it is simple. Try this:

declare @AlpaNumber nvarchar(50) = 'ABC'
declare @MyNumber int = 0
begin Try
select @MyNumber = case when ISNUMERIC(@AlpaNumber) = 1 then cast(@AlpaNumber as int) else 0 end
End Try
Begin Catch
    -- Do nothing
End Catch 

if exists(select * from mytable where mynumber = @MyNumber)
Begin
print 'Found'
End
Else
Begin
 print 'Not Found'
End

Honestly, the best way to limit files is on the server side. People can spoof file type on the client so taking in the full file name at server transfer time, parsing out the file type, and then returning a message is usually the best bet.

To put it in another way, can we replicate the appearance of these text views without using the android:textAppearance attribute?

Like biegleux already said:

• small represents 14sp
• medium represents 18sp
• large represents 22sp

If you want to use the small, medium or large value on any text in your Android app, you can just create a dimens.xml file in your values folder and define the text size there with the following 3 lines:

<dimen name="text_size_small">14sp</dimen>
<dimen name="text_size_medium">18sp</dimen>
<dimen name="text_size_large">22sp</dimen>

Here is an example for a TextView with large text from the dimens.xml file:

<TextView
  android:id="@+id/hello_world"
  android:text="hello world"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textSize="@dimen/text_size_large"/>

$(document).ready(function() {
    $('select#select_2').change(function() {
        var selectedText = $(this).find('option:selected').text();
        alert(selectedText);
    });
});

Fiddle

UrlConnection is an awkward API to work with. HttpClient is by far the better API and it'll spare you from loosing time searching how to achieve certain things like this stackoverflow question illustrates perfectly. I write this after having used the jdk HttpUrlConnection in several REST clients. Furthermore when it comes to scalability features (like threadpools, connection pools etc.) HttpClient is superior

Supplement to Mario Knezovic 's answer:

class IA
{
public:
  virtual int getNum() const = 0;
};

class BaseA : public IA
{
public:
 inline virtual int getNum() const final {return ...};
};

class ImplA : public BaseA {...};

IA* pa = ...;
...
ImplA* impla = static_cast<ImplA*>(pa);

//the following line should cause compiler to use the inlined function BaseA::getNum(), 
//instead of dynamic binding (via vtable or something).
//any class/subclass of BaseA will benefit from it

int n = impla->getNum();

The above code shows the theory, but not actually tested on real compilers. Much appreciated if anyone paste a disassembled output.

When it comes to DiSaSteR's answer, I noticed a different behavior. textBox.Text shows the text in the TextBox as it was before the user entered a new character, while e.Text shows the single character the user just entered. One challenge is that this character might not get appended to the end, but it will be inserted at the carret position:

private void salary_texbox_PreviewTextInput(object sender, TextCompositionEventArgs e){
  Regex regex = new Regex ( "[^0-9]+" );

  string text;
  if (textBox.CaretIndex==textBox.Text.Length) {
    text = textBox.Text + e.Text;
  } else {
    text = textBox.Text.Substring(0, textBox.CaretIndex)  + e.Text + textBox.Text.Substring(textBox.CaretIndex);
  }

  if(regex.IsMatch(text)){
      MessageBox.Show("Error");
  }
}

In a case statement, a , is the equivalent of || in an if statement.

case car
   when 'toyota', 'lexus'
      # code
end

Only install the Service Pack (VS10sp1-KB983509.msp) wasn't enough to me.

I had to uninstall the Visual Studio Team Explorer 2010 to continue the installation :)

Here is another construction which starts with the simplest number format and then, in a non-overlapping way, progressively adds more complex number formats:

Java regep:

(\d)|([1-9]\d+)|(\.\d+)|(\d\.\d*)|([1-9]\d+\.\d*)|([1-9]\d{0,2}(,\d{3})+(\.\d*)?)

As a Java String (note the extra \ needed to escape to \ and . since \ and . have special meaning in a regexp when on their own):

String myregexp="(\\d)|([1-9]\\d+)|(\\.\\d+)|(\\d\\.\\d*)|([1-9]\\d+\\.\\d*)|([1-9]\\d{0,2}(,\\d{3})+(\\.\\d*)?)";   

Explanation:

1. This regexp has the form A|B|C|D|E|F where A,B,C,D,E,F are themselves regexps that do not overlap. Generally, I find it easier to start with the simplest possible matches, A. If A misses matches you want, then create a B that is a minor modification of A and includes a bit more of what you want. Then, based on B, create a C that catches more, etc. I also find it easier to create regexps that don't overlap; it is easier to understand a regexp with 20 simple non-overlapping regexps connected with ORs rather than a few regexps with more complex matching. But, each to their own!

2. A is (\d) and matches exactly one of 0,1,2,3,4,5,6,7,8,9 which can't be simpler!

3. B is ([1-9]\d+) and only matches numbers with 2 or more digits, the first excluding 0 . B matches exactly one of 10,11,12,... B does not overlap A but is a small modification of A.

4. C is (.\d+) and only matches a decimal followed by one or more digits. C matches exactly one of .0 .1 .2 .3 .4 .5 .6 .7 .8 .9 .00 .01 .02 ... . .23000 ... C allows trailing eros on the right which I prefer: if this is measurement data, the number of trailing zeros indicates the level of precision. If you don't want the trailing zeros on the right, change (.\d+) to (.\d*[1-9]) but this also excludes .0 which I think should be allowed. C is also a small modification of A.

5. D is (\d.\d*) which is A plus decimals with trailing zeros on the right. D only matches a single digit, followed by a decimal, followed by zero or more digits. D matches 0. 0.0 0.1 0.2 ....0.01000...9. 9.0 9.1..0.0230000 .... 9.9999999999... If you want to exclude "0." then change D to (\d.\d+). If you want to exclude trailing zeros on the right, change D to (\d.\d*[1-9]) but this excludes 2.0 which I think should be included. D does not overlap A,B,or C.

6. E is ([1-9]\d+.\d*) which is B plus decimals with trailing zeros on the right. If you want to exclude "13.", for example, then change E to ([1-9]\d+.\d+). E does not overlap A,B,C or D. E matches 10. 10.0 10.0100 .... 99.9999999999... Trailing zeros can be handled as in 4. and 5.

7. F is ([1-9]\d{0,2}(,\d{3})+(.\d*)?) and only matches numbers with commas and possibly decimals allowing trailing zeros on the right. The first group ([1-9]\d{0,2}) matches a non-zero digit followed zero, one or two more digits. The second group (,\d{3})+ matches a 4 character group (a comma followed by exactly three digits) and this group can match one or more times (no matches means no commas!). Finally, (.\d*)? matches nothing, or matches . by itself, or matches a decimal . followed by any number of digits, possibly none. Again, to exclude things like "1,111.", change (.\d*) to (.\d+). Trailing zeros can be handled as in 4. or 5. F does not overlap A,B,C,D, or E. I couldn't think of an easier regexp for F.

Let me know if you are interested and I can edit above to handle the trailing zeros on the right as desired.

Create your custom object and implement Serializable. Next, you can use intent.putExtra("package.name.example", <your-serializable-object>).

In the second activity, you read it using getIntent().getSerializableExtra("package.name.example")

Otherwise, follow this and this page.

There is another way. If you're passing an object by reference, that object's properties will appear in the function's local scope. I know this works for Safari (haven't checked other browsers) and I don't know if this feature has a name, but the below example illustrates its use.

Although in practice I don't think that this offers any functional value beyond the technique you're already using, it's a little cleaner semantically. And it still requires passing a object reference or an object literal.

function sum({ a:a, b:b}) {
    console.log(a+'+'+b);
    if(a==undefined) a=0;
    if(b==undefined) b=0;
    return (a+b);
}

// will work (returns 9 and 3 respectively)
console.log(sum({a:4,b:5}));
console.log(sum({a:3}));

// will not work (returns 0)
console.log(sum(4,5));
console.log(sum(4));

One thing I discovered is that using the \include command will often insert and extra blank page. Riffing on the previous trick with the \let command, I inserted \let\include\input near the beginning of the document, and that got rid of most of the excessive blank pages.

The latest version of angular is only setup for evergreen browsers by default...

The current setup is for so-called "evergreen" browsers; the last versions of browsers that automatically update themselves. This includes Safari >= 10, Chrome >= 55 (including Opera), Edge >= 13 on the desktop, and iOS 10 and Chrome on mobile.
This also includes firefox, although not mentioned.

See here for more information on browser support along with a list of suggested polyfills for specific browsers. https://angular.io/guide/browser-support#polyfill-libs

To achieve this, go into polyfills.ts (in the src folder by default) and just uncomment the following imports:

/***************************************************************************************************
 * BROWSER POLYFILLS
 */

/** IE9, IE10 and IE11 requires all of the following polyfills. **/
 import 'core-js/es6/symbol';
 import 'core-js/es6/object';
 import 'core-js/es6/function';
 import 'core-js/es6/parse-int';
 import 'core-js/es6/parse-float';
 import 'core-js/es6/number';
 import 'core-js/es6/math';
 import 'core-js/es6/string';
 import 'core-js/es6/date';
 import 'core-js/es6/array';
 import 'core-js/es6/regexp';
 import 'core-js/es6/map';
 import 'core-js/es6/set';

Note that the comment is literally in the file, so this is easy to find.

If you are still having issues, you can downgrade the target property to es5 in tsconfig.json as @MikeDub suggested. What this does is change the compilation output of any es6 definitions to es5 definitions. For example, fat arrow functions (()=>{}) will be compiled to anonymous functions (function(){}). You can find a list of es6 supported browsers here.

Notes

• I was asked in the comments by @jackOfAll whether IE11 polyfills are loaded even if the user is in an evergreen browser which doesn't need them. The answer is, yes they are! The inclusion of the IE11 polyfills will take your polyfill file from ~162KB to ~258KB as of Aug 8 '17. I have invested in trying to solve this however it does not seem possible at this time.

• If you are getting errors in IE10 and below, go into you package.json and downgrade webpack-dev-server to 2.7.1 specifically. Versions higher than this no longer support "older" IE versions.

I'm using Rails 4.2.4 and couldn't work out why I was getting:

Can't verify CSRF token authenticity

I have in the layout:

<%= csrf_meta_tags %>

In the controller:

protect_from_forgery with: :exception

Invoking tcpdump -A -s 999 -i lo port 3000 was showing the header being set ( despite not needing to set the headers with ajaxSetup - it was done already):

X-CSRF-Token: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Content-Type: application/x-www-form-urlencoded; charset=UTF-8
X-Requested-With: XMLHttpRequest
DNT: 1
Content-Length: 125
authenticity_token=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

In the end it was failing because I had cookies switched off. CSRF doesn't work without cookies being enabled, so this is another possible cause if you're seeing this error.

setInterval(function() {
    updatechat();
}, 2000);

function updatechat() {
    alert('hello world');

Based on @SDahm's answer, this was an "optimal" solution for my tibble:

data %<>% lapply(type.convert) %>% as.data.table()

This requires dplyr and magrittr.

The reason why you get your error is because a "1 by n" matrix is different from an array of length n.

I recommend using hstack() and vstack() instead. Like this:

import numpy as np
a = np.arange(32).reshape(4,8) # 4 rows 8 columns matrix.
b = a[:,-1:]                    # last column of that matrix.

result = np.hstack((a,b))       # stack them horizontally like this:
#array([[ 0,  1,  2,  3,  4,  5,  6,  7,  7],
#       [ 8,  9, 10, 11, 12, 13, 14, 15, 15],
#       [16, 17, 18, 19, 20, 21, 22, 23, 23],
#       [24, 25, 26, 27, 28, 29, 30, 31, 31]])

Notice the repeated "7, 15, 23, 31" column. Also, notice that I used a[:,-1:] instead of a[:,-1]. My version generates a column:

array([[7],
       [15],
       [23],
       [31]])

Instead of a row array([7,15,23,31])

Edit: append() is much slower. Read this answer.

Thank you all for your contribution! I found the problem:

ITS A FIREBUG BUG !!!

My code works. I have asked the PHP Dev to change the input types hidden in to input type text. The disabled feature works. But the firebug console does not update this status!

you can test out this firebug bug by your self here http://jsbin.com/uneti3/3#. Thx to aSeptik for the example page.

update: 2. June 2012: Firebug in FF11 still has this bug.

In case you're using YAML and Twig for translations in Symfony, and want to use multi-line translations in Javascript, a carriage return is added right after the translation. So even the following code:

var javascriptVariable = "{{- 'key'|trans -}}";

Which has the following yml translation:

key: >
    This is a
    multi line 
    translation.

Will still result into the following code in html:

var javascriptVariable = "This is a multi line translation.
";

So, the minus sign in Twig does not solve this. The solution is to add this minus sign after the greater than sign in yml:

key: >-
    This is a
    multi line 
    translation.

Will have the proper result, multi line translation on one line in Twig:

var javascriptVariable = "This is a multi line translation.";

There's a .val() method:

If you've got an input with an id of txtEmail you can use the following code to access the value of the text box:

$("#txtEmail").val()

You can also use the val(string) method to set that value:

$("#txtEmail").val("something")

Modern Javascript implementations with the template syntax using backticks are also an easy way to assign an HTML block of code to a variable:

    const firstName = 'Sam';
    const fullName = 'Sam Smith';
    const htmlString = `<h1>Hello ${fullName}!</h1><p>This is some content \
        that will display. You can even inject your first name, ${firstName}, \
        in the code.</p><p><a href="http://www.google.com">Search</a> for \
        stuff on the Google website.</p>`;

It´s very simple to do:

Just add following attribute and code to your Main-method:

[STAThread]
void Main(string[] args])
{
   Application.EnableVisualStyles();
   //Do some stuff...
   while(!Exit)
   {
       Application.DoEvents(); //Now if you call "form.Show()" your form won´t be frozen
       //Do your stuff
   }
}

Now you´re fully able to show WinForms :)

You can change which python you're using with your IDE, if you've already downloaded python 3.x it shouldn't be too hard to switch. But your script works fine on python 3.x, I would just change

print ("your name is" + input_variable)

to

print ("your name is", input_variable)

Because with the comma it prints with a whitespace in between your name is and whatever the user inputted. AND: if you're using 2.7 just use raw_input instead of input.

For PySpark, you can also set the log level in your scripts with sc.setLogLevel("FATAL"). From the docs:

Control our logLevel. This overrides any user-defined log settings. Valid log levels include: ALL, DEBUG, ERROR, FATAL, INFO, OFF, TRACE, WARN

I'm not 100% on why (actually came here to search for the answer), but this also works, and doesn't require replacing all nan values.

import pandas as pd
import numpy as np

df = pd.DataFrame([["foo1"], ["foo2"], ["bar"], [np.nan]], columns=['a'])

newdf = df.loc[df['a'].str.contains('foo') == True]

Works with or without .loc.

I have no idea why this works, as I understand it when you're indexing with brackets pandas evaluates whatever's inside the bracket as either True or False. I can't tell why making the phrase inside the brackets 'extra boolean' has any effect at all.

Original question: "How to redirect using jQuery?", hence the answer implements jQuery >> Complimentary usage case.

To just redirect to a page with JavaScript:

window.location.href = "/contact/";

Or if you need a delay:

setTimeout(function () {
  window.location.href = "/contact/";
}, 2000);   // Time in milliseconds

jQuery allows you to select elements from a web page with ease. You can find anything you want on a page and then use jQuery to add special effects, react to user actions, or show and hide content inside or outside the element you have selected. All these tasks start with knowing how to select an element or an event.

$('a,img').on('click',function(e){
  e.preventDefault();
  $(this).animate({
    opacity: 0 //Put some CSS animation here
  }, 500);
  setTimeout(function(){
    // OK, finished jQuery staff, let's go redirect
    window.location.href = "/contact/";
  },500);
});

Imagine someone wrote a script/plugin with 10000 lines of code. With jQuery you can connect to this code with just a line or two.

Just use a bytearray (Python 2.6 and later) which represents a mutable sequence of bytes

>>> key = bytearray([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])
>>> key
bytearray(b'\x13\x00\x00\x00\x08\x00')

Indexing get and sets the individual bytes

>>> key[0]
19
>>> key[1]=0xff
>>> key
bytearray(b'\x13\xff\x00\x00\x08\x00')

and if you need it as a str (or bytes in Python 3), it's as simple as

>>> bytes(key)
'\x13\xff\x00\x00\x08\x00'

You are calling GridView.RenderControl(htmlTextWriter), hence the page raises an exception that a Server-Control was rendered outside of a Form.

You could avoid this execption by overriding VerifyRenderingInServerForm

public override void VerifyRenderingInServerForm(Control control)
{
  /* Confirms that an HtmlForm control is rendered for the specified ASP.NET
     server control at run time. */
}

See here and here.

Yes, you can set the icons to the white color. here is how it worked for me.

Bootstrap <3

HTML

<i class="icon-ok icon-white"></i>

This would make your icon appear white.

I needed to make sure that my scripts are entirely portable between various machines, shells and even cygwin versions. Further, my colleagues who were the ones I had to write the scripts for, are programmers, so I ended up using this:

for ((i=1;i<=$#;i++)); 
do

    if [ ${!i} = "-s" ] 
    then ((i++)) 
        var1=${!i};

    elif [ ${!i} = "-log" ];
    then ((i++)) 
        logFile=${!i};  

    elif [ ${!i} = "-x" ];
    then ((i++)) 
        var2=${!i};    

    elif [ ${!i} = "-p" ]; 
    then ((i++)) 
        var3=${!i};

    elif [ ${!i} = "-b" ];
    then ((i++)) 
        var4=${!i};

    elif [ ${!i} = "-l" ];
    then ((i++)) 
        var5=${!i}; 

    elif [ ${!i} = "-a" ];
    then ((i++)) 
        var6=${!i};
    fi

done;

Rationale: I included a launcher.sh script as well, since the whole operation had several steps which were quasi independent on each other (I'm saying "quasi", because even though each script could be run on its own, they were usually all run together), and in two days I found out, that about half of my colleagues, being programmers and all, were too good to be using the launcher file, follow the "usage", or read the HELP which was displayed every time they did something wrong and they were making a mess of the whole thing, running scripts with arguments in the wrong order and complaining that the scripts didn't work properly. Being the choleric I am I decided to overhaul all my scripts to make sure that they are colleague-proof. The code segment above was the first thing.

If you only need the first match, then use re.search instead of re.findall:

>>> m = re.search('\d+', 'aa33bbb44')
>>> m.group()
'33'
>>> m = re.search('\d+', 'aazzzbbb')
>>> m.group()
Traceback (most recent call last):
  File "<pyshell#281>", line 1, in <module>
    m.group()
AttributeError: 'NoneType' object has no attribute 'group'

Then you can use m as a checking condition as:

>>> m = re.search('\d+', 'aa33bbb44')
>>> if m:
        print('First number found = {}'.format(m.group()))
    else:
        print('Not Found')


First number found = 33

There Are 2 ways to return a string from the controller to the view:

First

You could return only the string, but it will not be included in your .cshtml file. it will be just a string appearing in your browser.

Second

You could return a string as the Model object of View Result.

Here is the code sample to do this:

public class HomeController : Controller
{
    // GET: Home
    // this will return just a string, not html
    public string index()
    {
        return "URL to show";
    }

    public ViewResult AutoProperty()
    {   
        string s = "this is a string ";
        // name of view , object you will pass
        return View("Result", s);

    }
}

In the view file to run AutoProperty, It will redirect you to the Result view and will send s
code to the view

<!--this will make this file accept string as it's model-->
@model string

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Result</title>
</head>
<body>
    <!--this will represent the string -->
    @Model
</body>
</html>

I run this at http://localhost:60227/Home/AutoProperty.

Delete your source tree that was gunzipped or gzipped and extracted to folder and reextract again. Supply your options again

./configure --with-option=/path/etc ...

Then if all libs are present, your make should succeed.

If your web application is configured to impersonate a client, then using a trusted connection will potentially have a negative performance impact. This is because each client must use a different connection pool (with the client's credentials).

Most web applications don't use impersonation / delegation, and hence don't have this problem.

See this MSDN article for more information.

This seems to work for me:

>>>a = ['x', 'y', 'z']
>>>type(a)
<class 'list'>
>>>isinstance(a, list)
True

set "html" option to true if you want to have html into tooltip. Actual html is determined by option "title" (link's title attribute shouldn't be set)

$('#example1').tooltip({placement: 'bottom', title: '<p class="testtooltip">par</p>', html: true});

Live sample

You want to use the onblur event.

<input type="text" name="name" value="value" onblur="alert(1);"/>

 user@M063:/var/www/html/app/.git/objects$ sudo chmod 777 -R .git/objects
 user@M063:/var/www/html/app/.git/objects$ sudo chown -R user:user .git/objects/

The problem is

listModel.addElement(listaRosa.getSelectedValue());
listModel.removeElement(listaRosa.getSelectedValue());

you may be adding an element and immediatly removing it since both add and remove operations are on the same listModel.

Try

private void aggiungiTitolareButtonActionPerformed(java.awt.event.ActionEvent evt) {                                                       

    DefaultListModel lm2 = (DefaultListModel) listaTitolari.getModel();
    DefaultListModel lm1  = (DefaultListModel) listaRosa.getModel();
    if(lm2 == null)
    {
        lm2 = new DefaultListModel();
        listaTitolari.setModel(lm2);
    }
    lm2.addElement(listaTitolari.getSelectedValue());
    lm1.removeElement(listaTitolari.getSelectedValue());        
} 

You can use json.js from http://www.json.org/js.html to change json data to string data.

If the original size is 100 x 100 and you want to scale it to 50 x 50, use scaledSize instead of Size.

var icon = {
    url: "../res/sit_marron.png", // url
    scaledSize: new google.maps.Size(50, 50), // scaled size
    origin: new google.maps.Point(0,0), // origin
    anchor: new google.maps.Point(0, 0) // anchor
};

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(lat, lng),
    map: map,
    icon: icon
});

"std" is a namespace used for STL (Standard Template Library). Please refer to https://en.wikipedia.org/wiki/Namespace#Use_in_common_languages

You can either write using namespace std; before using any stl functions, variables or just insert std:: before them.

There's an important thing that people always seem to overlook:

You can pass a plain array to something which accepts an IList<T> parameter, and then you can call IList.Add() and will receive a runtime exception:

Unhandled Exception: System.NotSupportedException: Collection was of a fixed size.

For example, consider the following code:

private void test(IList<int> list)
{
    list.Add(1);
}

If you call that as follows, you will get a runtime exception:

int[] array = new int[0];
test(array);

This happens because using plain arrays with IList<T> violates the Liskov substitution principle.

For this reason, if you are calling IList<T>.Add() you may want to consider requiring a List<T> instead of an IList<T>.

An element styled as follows will be aligned vertically to middle:

.content{
     position:relative;
     -webkit-transform: translateY(-50%);
     -ms-transform: translateY(-50%);
     transform: translateY(-50%);
     top:50%;
}

However, the parent element must have a fixed height. See this fiddle: https://jsfiddle.net/15d0qfdg/12/

If you want to save the changes on the log messages, use the batch script from the answer above from @patmortech (https://stackoverflow.com/a/468475),
who copied the script from https://stackoverflow.com/a/68850,
and add these lines between if "%bIsEmpty%" == "true" goto ERROR_EMPTY and goto :eofbefore:

set outputFile=%repos%\log-change-history.txt

echo User '%user%' changes log message in rev %rev% on %date% %time%.>>%outputFile%
echo ----- Old message: ----->>%outputFile%
svnlook propget --revprop %repos% svn:log -r %rev% >>%outputFile%
echo.>>%outputFile%
echo ----- New message: ----->>%outputFile%
for /f "tokens=*" %%g in ('find /V ""') do (echo %%g >>%outputFile%)
echo ---------->>%outputFile%
echo.>>%outputFile%

It will create a text file log-change-history.txt in the repo folder on the server and append each log change notification.

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:

ffmpeg -i input.mov -qscale 0 output.mp4

Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):

ffmpeg -i input.mov -q:v 0 output.mp4

You can do this using cross apply

SELECT c.BalanceDue AS BalanceDue
FROM Invoices
cross apply (select (InvoiceTotal - PaymentTotal - CreditTotal) as BalanceDue) as c
WHERE  c.BalanceDue  > 0;

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
}

For a larger number of optional parameters, a single parameter of Dictionary could be used with the ContainsKey method. I like this approach because it allows me to pass a List or a T individually without having to create a whole other method (nice if parameters are to be used as filters, for example).

Example (new Dictionary<string,Object>() would be passed if no optional parameters are desired):

public bool Method(string ParamA, Dictionary<string,Object> AddlParams) {
    if(ParamA == "Alpha" && (AddlParams.ContainsKey("foo") || AddlParams.ContainsKey("bar"))) {
        return true;
    } else {
        return false;
    }
}

I try all of above code but any code is not working for my website.then i try this code and This code is running perfect for my website. You can use the following Rule in htaccess :

<IfModule mod_rewrite.c>
Options +FollowSymLinks
RewriteEngine On

//Redirect http to https
RewriteCond %{SERVER_PORT} 80
RewriteCond %{HTTP_HOST} ^(www\.)?example\.com
RewriteRule ^(.*)$ https://www.example.com/$1 [R,L]

//Redirect non-www to www
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ https://www.example.com/$1 [L,R=301]

</IfModule>

Change example.com with your domain name and sorry for my poor english.

It almost always works for me when I use bioconductor as source and then invoke biocLite. Example:

source("https://bioconductor.org/biocLite.R")
biocLite("preprocessCore")

jQuery has a toggleClass function:

<button class="switch">Click me</button>

<div class="text-block collapsed pressed">some text</div>

<script>    
    $('.switch').on('click', function(e) {
      $('.text-block').toggleClass("collapsed pressed"); //you can list several class names 
      e.preventDefault();
    });
</script>

You can fetch and then check out only one file in this way:

git fetch
git checkout -m <revision> <yourfilepath>
git add <yourfilepath>
git commit

Regarding the git checkout command:

• <revision> -- a branch name, i.e. origin/master
• <yourfilepath> does not include the repository name (that you can get from clicking copy path button on a file page on GitHub), i.e. README.md

In case anyone else is running in to the same problem, the only solution I could find that satisfied me was to have the canvas cover everything and then to raise the Z-index of all clickable elements. You can't draw on them, but at least they are clickable...

NOTE: This answer obviously defeats the purpose of SSL and should be used sparingly as a last resort.

For those having issues with scripts that download scripts that download scripts and want a quick fix, create a file called ~/.curlrc

With the contents

--insecure

This will cause curl to ignore SSL certificate problems by default.

Make sure you delete the file when done.

UPDATE

12 days later I got notified of an upvote on this answer, which made me go "Hmmm, did I follow my own advice remember to delete that .curlrc?", and discovered I hadn't. So that really underscores how easy it is to leave your curl insecure by following this method.

Is this what you are trying? I have commented the code so that you will not have any problem understanding it.

Sub Sample()
    Dim ws As Worksheet
    Dim lRow As Long, lCol As Long
    Dim rng As Range

    '~~> Set this to the relevant worksheet
    Set ws = [Sheet1]

    With ws
        '~~> Get the last row and last column
        lRow = .Range("A" & .Rows.Count).End(xlUp).Row
        lCol = .Cells(1, .Columns.Count).End(xlToLeft).Column

        '~~> Set the range
        Set rng = .Range(.Cells(lRow, 1), .Cells(lRow, lCol))

        With rng
            Debug.Print .Address
            '
            '~~> What ever you want to do with the address
            '
        End With
    End With
End Sub

BTW I am assuming that LastRow is the same for all rows and same goes for the columns. If that is not the case then you will have use .Find to find the Last Row and the Last Column. You might want to see THIS

In terms of coding, a bidirectional relationship is more complex to implement because the application is responsible for keeping both sides in synch according to JPA specification 5 (on page 42). Unfortunately the example given in the specification does not give more details, so it does not give an idea of the level of complexity.

When not using a second level cache it is usually not a problem to do not have the relationship methods correctly implemented because the instances get discarded at the end of the transaction.

When using second level cache, if anything gets corrupted because of wrongly implemented relationship handling methods, this means that other transactions will also see the corrupted elements (the second level cache is global).

A correctly implemented bi-directional relationship can make queries and the code simpler, but should not be used if it does not really make sense in terms of business logic.

For PHP, put this line of code before you start printing your XML:

while(ob_get_level()) ob_end_clean();

I could not get IE8+ to work by adding a jQuery event handler to the file input type. I had to go old-school and add the the onchange="" attribute to the input tag:

<input type='file' onchange='getFilename(this)'/>

function getFileName(elm) {
   var fn = $(elm).val();
   ....
}

EDIT:

function getFileName(elm) {
   var fn = $(elm).val();
   var filename = fn.match(/[^\\/]*$/)[0]; // remove C:\fakename
   alert(filename);
}
