Using Kotlin

    val data = "{\"ApiInfo\":{\"description\":\"userDetails\",\"status\":\"success\"},\"userDetails\":{\"Name\":\"somename\",\"userName\":\"value\"},\"pendingPushDetails\":[]}\n"
    
try {
      val jsonObject = JSONObject(data)
      val infoObj = jsonObject.getJSONObject("ApiInfo")
    } catch (e: Exception) {
    }

Yes -- parseFloat.

parseFloat(document.getElementById(amtid4).innerHTML);

For formatting numbers, use toFixed:

var num = parseFloat(document.getElementById(amtid4).innerHTML).toFixed(2);

num is now a string with the number formatted with two decimal places.

serialize() is the function you are looking for. It will return a string representation of its input array or object in a PHP-specific internal format. The string may be converted back to its original form with unserialize().

But beware, that not all objects are serializable, or some may be only partially serializable and unable to be completely restored with unserialize().

$array = array(1,2,3,'foo');
echo serialize($array);

// Prints
a:4:{i:0;i:1;i:1;i:2;i:2;i:3;i:3;s:3:"foo";}

Addendum to @sjngm's answer:

They both also ignore whitespace:

var foo = "    3     ";
console.log(parseInt(foo)); // 3
console.log(Number(foo)); // 3

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

If have a solution without jQuery. A link where you can see a working example: http://www.letmaier.com/_selectbox/select_general_code.html (styled with more css)

The style-section of my solution:

<style>
#container { margin: 10px; padding: 5px; background: #E7E7E7; width: 300px; background: #ededed); }
#ul1 { display: none; list-style-type: none; list-style-position: outside; margin: 0px; padding: 0px; }
#container a {  color: #333333; text-decoration: none; }
#container ul li {  padding: 3px;   padding-left: 0px;  border-bottom: 1px solid #aaa;  font-size: 0.8em; cursor: pointer; }
#container ul li:hover { background: #f5f4f4; }
</style>

Now the HTML-code inside the body-tag:

<form>
<div id="container" onMouseOver="document.getElementById('ul1').style.display = 'block';" onMouseOut="document.getElementById('ul1').style.display = 'none';">
Select one entry: <input name="entrytext" type="text" disabled readonly>
<ul id="ul1">
    <li onClick="document.forms[0].elements['entrytext'].value='Entry 1'; document.getElementById('ul1').style.display = 'none';"><a href="#">Entry 1</a></li>
    <li onClick="document.forms[0].elements['entrytext'].value='Entry 2'; document.getElementById('ul1').style.display = 'none';"><a href="#">Entry 2</a></li>
    <li onClick="document.forms[0].elements['entrytext'].value='Entry 3'; document.getElementById('ul1').style.display = 'none';"><a href="#">Entry 3</a></li>
</ul>
</div>
</form>

All above answers and other online posts mention following:

• With declarative programming, you write code that describes what you want, but not necessarily how to get it
• You should prefer declarative programming over the imperative programming

What they have not told us is how to achieve it. For part of the program to be more declarative, other parts must provide the abstraction to hide the implementation details (which are the imperative codes).

• E.g., LINQ is more declarative than loops (for, while, etc.), e.g., you can use list.Where() to get a new filtered list. For this to work, Microsoft has done all the heavy lifting behind the LINQ abstraction.

In fact, one of the reason functional programming and functional libraries are more declarative is because they have abstracted away loops and list creations, hiding all the implementation details (most likely imperative codes with loops) behind the scene.

In any program, you will always have both imperative and declarative codes, what you should aim for is to hide all imperative codes behind the domain-specific abstractions, so that other parts of the program can use them declaratively.

Finally, although functional programming and LINQ can make your program more declarative, you can always make it even more declarative by providing more abstractions. For example:

// JavaScript example

// Least declarative
const bestProducts = [];
for(let i = 0; i < products.length; i++) {
    let product = products[i];
    if (product.rating >= 5 && product.price < 100) {
        bestProducts.push(product);
    }
}


// More declarative
const bestProducts = products.filter(function(product) {
    return product.rating >= 5 && product.price < 100;
});

// Most declarative, implementation details are hidden in a function
const bestProducts = getBestProducts();

P.S. the extreme of declarative programming is to invent new domain specific languages (DSL):

1. String Search: Regular Expression instead of custom imperative code
2. React.js: JSX instead of direct DOM manipulation
3. AWS CloudFormation: YAML instead of CLI
4. Relational Database: SQL instead of older read–write APIs such as ISAM or VSAM.

Just using the Array iteration methods built into JS is fine for this:

var result1 = [_x000D_
    {id:1, name:'Sandra', type:'user', username:'sandra'},_x000D_
    {id:2, name:'John', type:'admin', username:'johnny2'},_x000D_
    {id:3, name:'Peter', type:'user', username:'pete'},_x000D_
    {id:4, name:'Bobby', type:'user', username:'be_bob'}_x000D_
];_x000D_
_x000D_
var result2 = [_x000D_
    {id:2, name:'John', email:'[email protected]'},_x000D_
    {id:4, name:'Bobby', email:'[email protected]'}_x000D_
];_x000D_
_x000D_
var props = ['id', 'name'];_x000D_
_x000D_
var result = result1.filter(function(o1){_x000D_
    // filter out (!) items in result2_x000D_
    return !result2.some(function(o2){_x000D_
        return o1.id === o2.id;          // assumes unique id_x000D_
    });_x000D_
}).map(function(o){_x000D_
    // use reduce to make objects with only the required properties_x000D_
    // and map to apply this to the filtered array as a whole_x000D_
    return props.reduce(function(newo, name){_x000D_
        newo[name] = o[name];_x000D_
        return newo;_x000D_
    }, {});_x000D_
});_x000D_
_x000D_
document.body.innerHTML = '<pre>' + JSON.stringify(result, null, 4) +_x000D_
        '</pre>';

If you are doing this a lot, then by all means look at external libraries to help you out, but it's worth learning the basics first, and the basics will serve you well here.

You can check the existence of a symlink and that it is not broken with:

[ -L ${my_link} ] && [ -e ${my_link} ]

So, the complete solution is:

if [ -L ${my_link} ] ; then
   if [ -e ${my_link} ] ; then
      echo "Good link"
   else
      echo "Broken link"
   fi
elif [ -e ${my_link} ] ; then
   echo "Not a link"
else
   echo "Missing"
fi

-L tests whether there is a symlink, broken or not. By combining with -e you can test whether the link is valid (links to a directory or file), not just whether it exists.

Using file:///// just doesn't work if security settings are set to even a moderate level.

If you just want users to be able to download/view files* located on a network or share you can set up a Virtual Directory in IIS. On the Properties tab make sure the "A share located on another computer" is selected and the "Connect as..." is an account that can see the network location.

Link to the virtual directory from your webpage (e.g. http://yoursite/yourvirtualdir/) and this will open up a view of the directory in the web browser.

*You can allow write permissions on the virtual directory to allow users to add files but not tried it and assume network permissions would override this setting.

ffill now has it's own method pd.DataFrame.ffill

df.ffill()

     0    1    2
0  1.0  2.0  3.0
1  4.0  2.0  3.0
2  4.0  2.0  9.0

The => operator is used to assign key-value pairs in an associative array. For example:

$fruits = array(
  'Apple'  => 'Red',
  'Banana' => 'Yellow'
);

It's meaning is similar in the foreach statement:

foreach ($fruits as $fruit => $color)
  echo "$fruit is $color in color.";

This helped me find the "Dynamic web project" in Eclipse 2020-12 version. Restart the eclipse and go to file->new->other->web and you will see project will be available.

One line of jQuery does it all!

$("#myCombobox option[text='it\'s me']").attr("selected","selected"); 

use this..

$(".content_box a:not('.button')")

The easiest thing to do, if you do not have a reader, is to open the MD file with a text editor and then write the MD file out as an HTML file and then double click to view it with browser.

In my case the error states that the assemly

Oracle.DataAccess, Version=2.112.3.0, Culture=neutral, PublicKeyToken=89b483f429c47342

is missing.

When I run gacutil.exe /l 'Oracle.DataAccess' the result was:

The Global Assembly Cache contains the following assemblies:
Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342, processorArchitecture=x86

Number of items = 1

At this moment I have just installed the oracle client: win32_11gR2_client

Then I installed oracle developer tools ODTwithODAC112030_deleloper_tool

Now gacutil is saying:

The Global Assembly Cache contains the following assemblies:
Oracle.DataAccess, Version=2.112.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342, processorArchitecture=x86

Number of items = 2

Fixed, one totally missing assembly case

public void printsOccurences(List<String> words)
{
    var selectQuery =
        from word in words
        group word by word into g
        select new {Word = g.Key, Count = g.Count()};
    foreach(var word in selectQuery)
        Console.WriteLine($"{word.Word}: {word.Count}");*emphasized text*
}

splice() changes the original array whereas slice() doesn't but both of them returns array object.

See the examples below:

var array=[1,2,3,4,5];
console.log(array.splice(2));

This will return [3,4,5]. The original array is affected resulting in array being [1,2].

var array=[1,2,3,4,5]
console.log(array.slice(2));

This will return [3,4,5]. The original array is NOT affected with resulting in array being [1,2,3,4,5].

Below is simple fiddle which confirms this:

//splice_x000D_
var array=[1,2,3,4,5];_x000D_
console.log(array.splice(2));_x000D_
_x000D_
//slice_x000D_
var array2=[1,2,3,4,5]_x000D_
console.log(array2.slice(2));_x000D_
_x000D_
_x000D_
console.log("----after-----");_x000D_
console.log(array);_x000D_
console.log(array2);

You can set display attribute as none to hide a label.

<label id="excel-data-div" style="display: none;"></label>

Like that

var purchCount = (from purchase in myBlaContext.purchases select purchase).Count();

or even easier

var purchCount = myBlaContext.purchases.Count()

Simply use datetime.datetime.strptime:

import datetime
stime = "01/12/2011"
print(datetime.datetime.strptime(stime, "%d/%m/%Y").timestamp())

Result:

1322697600

To use UTC instead of the local timezone use .replace:

datetime.datetime.strptime(stime, "%d/%m/%Y").replace(tzinfo=datetime.timezone.utc).timestamp()

using (StreamWriter writer = File.AppendText(LoggingPath))
{
    writer.WriteLine("Text");
}

I just tried set ~=%userprofile% and that works too if you want to keep using the same habit

You can then use %~% instead.

If the number of elements in the array is not given, you can alternatively make use of list comprehension like:

str_arr = raw_input().split(' ') //will take in a string of numbers separated by a space
arr = [int(num) for num in str_arr]

cd ,

it will give the current directory

D:\Folder\subFolder>cd ,
D:\Folder\subFolder

You don't need to rely on the preprocessor to ensure your enums and strings are in sync. To me using macros tend to make the code harder to read.

Using Enum And An Array Of Strings

enum fruit                                                                   
{
    APPLE = 0, 
    ORANGE, 
    GRAPE,
    BANANA,
    /* etc. */
    FRUIT_MAX                                                                                                                
};   

const char * const fruit_str[] =
{
    [BANANA] = "banana",
    [ORANGE] = "orange",
    [GRAPE]  = "grape",
    [APPLE]  = "apple",
    /* etc. */  
};

Note: the strings in the fruit_str array don't have to be declared in the same order as the enum items.

How To Use It

printf("enum apple as a string: %s\n", fruit_str[APPLE]);

Adding A Compile Time Check

If you are afraid to forget one string, you can add the following check:

#define ASSERT_ENUM_TO_STR(sarray, max) \                                       
  typedef char assert_sizeof_##max[(sizeof(sarray)/sizeof(sarray[0]) == (max)) ? 1 : -1]

ASSERT_ENUM_TO_STR(fruit_str, FRUIT_MAX);

An error would be reported at compile time if the amount of enum items does not match the amount of strings in the array.

First Check that is image exists? if yes then simply Call unlink(your file path) function to remove you file otherwise show message to the user.

              if (file_exists($filePath)) 
               {
                 unlink($filePath);
                  echo "File Successfully Delete."; 
              }
              else
              {
               echo "File does not exists"; 
              }

I just wanted to extend Alex's great answer to make it appropriate if you happen to want to duplicate an entire set of records:

SET @x=7;
CREATE TEMPORARY TABLE tmp SELECT * FROM invoices;
UPDATE tmp SET id=id+@x;
INSERT INTO invoices SELECT * FROM tmp;

I just had to do this and found Alex's answer a perfect jumping off point!. Of course, you have to set @x to the highest row number in the table (I'm sure you could grab that with a query). This is only useful in this very specific situation, so be careful using it when you don't wish to duplicate all rows. Adjust the math as necessary.

It's just part of the horrendous mess which is the Java date/time API. Listing what's wrong with it would take a very long time (and I'm sure I don't know half of the problems). Admittedly working with dates and times is tricky, but aaargh anyway.

Do yourself a favour and use Joda Time instead, or possibly JSR-310.

EDIT: As for the reasons why - as noted in other answers, it could well be due to old C APIs, or just a general feeling of starting everything from 0... except that days start with 1, of course. I doubt whether anyone outside the original implementation team could really state reasons - but again, I'd urge readers not to worry so much about why bad decisions were taken, as to look at the whole gamut of nastiness in java.util.Calendar and find something better.

One point which is in favour of using 0-based indexes is that it makes things like "arrays of names" easier:

// I "know" there are 12 months
String[] monthNames = new String[12]; // and populate...
String name = monthNames[calendar.get(Calendar.MONTH)];

Of course, this fails as soon as you get a calendar with 13 months... but at least the size specified is the number of months you expect.

This isn't a good reason, but it's a reason...

EDIT: As a comment sort of requests some ideas about what I think is wrong with Date/Calendar:

• Surprising bases (1900 as the year base in Date, admittedly for deprecated constructors; 0 as the month base in both)
• Mutability - using immutable types makes it much simpler to work with what are really effectively values
• An insufficient set of types: it's nice to have Date and Calendar as different things, but the separation of "local" vs "zoned" values is missing, as is date/time vs date vs time
• An API which leads to ugly code with magic constants, instead of clearly named methods
• An API which is very hard to reason about - all the business about when things are recomputed etc
• The use of parameterless constructors to default to "now", which leads to hard-to-test code
• The Date.toString() implementation which always uses the system local time zone (that's confused many Stack Overflow users before now)

This answer about updating column from a part of another column in the same table.

update T1
set domainname = (New value) --Example: (SELECT LEFT(TableName.col, CHARINDEX('@',TableName.col)-1) STRIPPED_STRING FROM TableName where TableName.col = T2.Emp_ID)
from TableName T1
INNER JOIN
    TableName T2
ON 
    T1.ID= T2.ID;

Just Clear the table body.

$("#tblbody").html("");

I had to move domain, username, password from

client.ClientCredentials.UserName.UserName = domain + "\\" + username; client.ClientCredentials.UserName.Password = password

to

client.ClientCredentials.Windows.ClientCredential.UserName = username; client.ClientCredentials.Windows.ClientCredential.Password = password; client.ClientCredentials.Windows.ClientCredential.Domain = domain;

like other said, clear and fill worked for me:

    var elem = $('#input_field');
    var val = elem.val();
    elem.focus().val('').val(val);

May be by :

SELECT DISTINCT email,id FROM table where id='2';

Why not:

ls *.{mp3,exe,mp4}

I'm not sure where I learned it - but I've been using this.

That's the same question I came across today and want to round a number and return float value up to a given decimal place and it must not be string (as returned from number_format) the answer is

echo sprintf('%.' . $decimalPlaces . 'f', round($number, $decimalPlaces));

>>> import requests
>>> response = requests.get('https://website.com/id', headers={'Authorization': 'access_token myToken'})

If the above doesnt work , try this:

>>> import requests
>>> response = requests.get('https://api.buildkite.com/v2/organizations/orgName/pipelines/pipelineName/builds/1230', headers={ 'Authorization': 'Bearer <your_token>' })
>>> print response.json()

I am using the below commands for this:

set lines=50     " For increasing the height to 50 lines (vertical)
set columns=200  " For increasing the width to 200 columns (horizontal)

The digest cycle is a synchronous call. It won't yield control to the browser's event loop until it is done. There are a few ways to deal with this. The easiest way to deal with this is to use the built in $timeout, and a second way is if you are using underscore or lodash (and you should be), call the following:

$timeout(function(){
    //any code in here will automatically have an apply run afterwards
});

or if you have lodash:

_.defer(function(){$scope.$apply();});

We tried several workarounds, and we hated injecting $rootScope into all of our controllers, directives, and even some factories. So, the $timeout and _.defer have been our favorite so far. These methods successfully tell angular to wait until the next animation loop, which will guarantee that the current scope.$apply is over.

AngularJS form elements look for the required attribute to perform validation functions. ng-required allows you to set the required attribute depending on a boolean test (for instance, only require field B - say, a student number - if the field A has a certain value - if you selected "student" as a choice)

As an example, <input required> and <input ng-required="true"> are essentially the same thing

If you are wondering why this is this way, (and not just make <input required="true"> or <input required="false">), it is due to the limitations of HTML - the required attribute has no associated value - its mere presence means (as per HTML standards) that the element is required - so angular needs a way to set/unset required value (required="false" would be invalid HTML)

You record audio and video using the same MediaRecorder class. It's pretty simple. Here's an example.

import React, { Component } from "react";
import axios from "axios";

const CancelToken = axios.CancelToken;

let cancel;

class Abc extends Component {
  componentDidMount() {
    this.Api();
  }

  Api() {
      // Cancel previous request
    if (cancel !== undefined) {
      cancel();
    }
    axios.post(URL, reqBody, {
        cancelToken: new CancelToken(function executor(c) {
          cancel = c;
        }),
      })
      .then((response) => {
        //responce Body
      })
      .catch((error) => {
        if (axios.isCancel(error)) {
          console.log("post Request canceled");
        }
      });
  }

  render() {
    return <h2>cancel Axios Request</h2>;
  }
}

export default Abc;

Yes, according to HTML5 drafts you can use the pattern attribute to specify the allowed input using a regular expression. For some types of data, you can use special input fields like <input type=email>. But these features still widely lack support or have qualitatively poor support.

I do not think that this can be done. Here is some code copied with no modifications from Chip Pearson's site: http://www.cpearson.com/excel/UnSelect.aspx.

UnSelectActiveCell

This procedure will remove the Active Cell from the Selection.

Sub UnSelectActiveCell()
    Dim R As Range
    Dim RR As Range
    For Each R In Selection.Cells
        If StrComp(R.Address, ActiveCell.Address, vbBinaryCompare) <> 0 Then
            If RR Is Nothing Then
                Set RR = R
            Else
                Set RR = Application.Union(RR, R)
            End If
        End If
    Next R
    If Not RR Is Nothing Then
        RR.Select
    End If
End Sub

UnSelectCurrentArea

This procedure will remove the Area containing the Active Cell from the Selection.

Sub UnSelectCurrentArea()
    Dim Area As Range
    Dim RR As Range

    For Each Area In Selection.Areas
        If Application.Intersect(Area, ActiveCell) Is Nothing Then
            If RR Is Nothing Then
                Set RR = Area
            Else
                Set RR = Application.Union(RR, Area)
            End If
        End If
    Next Area
    If Not RR Is Nothing Then
        RR.Select
    End If
End Sub

One more way of convenient placement of Environment.NewLine in format string. The idea is to create string extension method that formats string as usual but also replaces {nl} in text with Environment.NewLine

Usage

   " X={0} {nl} Y={1}{nl} X+Y={2}".FormatIt(1, 2, 1+2);
   gives:
    X=1
    Y=2
    X+Y=3

Code

    ///<summary>
    /// Use "string".FormatIt(...) instead of string.Format("string, ...)
    /// Use {nl} in text to insert Environment.NewLine 
    ///</summary>
    ///<exception cref="ArgumentNullException">If format is null</exception>
    [StringFormatMethod("format")]
    public static string FormatIt(this string format, params object[] args)
    {
        if (format == null) throw new ArgumentNullException("format");

        return string.Format(format.Replace("{nl}", Environment.NewLine), args);
    }

Note

1. If you want ReSharper to highlight your parameters, add attribute to the method above

   [StringFormatMethod("format")]

2. This implementation is obviously less efficient than just String.Format

3. Maybe one, who interested in this question would be interested in the next question too: Named string formatting in C#

You can also just clone the repo, after cloning is done, just pick the folder or vile that you want. To clone:

git clone https://github.com/somegithubuser/somgithubrepo.git

then go to the cloned DIR and find your file or DIR you want to copy.

this may also work.

export GNUPLOT_DRIVER_DIR=

Here Response.Write():to display only string and you can not display any other data type values like int,date,etc.Conversion(from one data type to another) is not allowed. whereas Response .Output .Write(): you can display any type of data like int, date ,string etc.,by giving index values.

Here is example:

protected void Button1_Click(object sender, EventArgs e)
    {
       Response.Write ("hi good morning!"+"is it right?");//only strings are allowed        
       Response.Write("Scott is {0} at {1:d}", "cool", DateTime.Now);//this will give error(conversion is not allowed)
       Response.Output.Write("\nhi goood morning!");//works fine
       Response.Output.Write("Jai is {0} on {1:d}", "cool", DateTime.Now);//here the current date will be converted into string and displayed
    }

Here's a working solution (2019): put this code inside your login logic;

If you want to check the python version in a particular cond environment you can also use conda list python

Node is used to represent tags in general. Divided to 3 types:

Attribute Note: is node which inside its has attributes. Exp: <p id=”123”></p>

Text Node: is node which between the opening and closing its have contian text content. Exp: <p>Hello</p>

Element Node : is node which inside its has other tags. Exp: <p><b></b></p>

Each node may be types simultaneously, not necessarily only of a single type.

Element is simply a element node.

I had this problem with Blend for Visual Studio 2015. The Toolbox would just not appear anymore. This turns out to be because Blend is not Visual Studio!

(You can edit your code in Blend and build and run it... It certainly seems like Visual Studio, but it isn't. I'm not sure what the purpose of Blend is...)

You can tell you are in Blend if the task bar icon has big "B" in it. To switch from Blend to Visual Studio, go to View-> Edit in Visual Studio.... It will open up another application that looks just like Blend, except the Solution Explorer is on the right instead of the left, and now you have a toolbox...

Use msexcel-builder. Install it with:

npm install msexcel-builder

Then:

// Create a new workbook file in current working-path 
var workbook = excelbuilder.createWorkbook('./', 'sample.xlsx')

// Create a new worksheet with 10 columns and 12 rows 
var sheet1 = workbook.createSheet('sheet1', 10, 12);

// Fill some data 
sheet1.set(1, 1, 'I am title');
for (var i = 2; i < 5; i++)
  sheet1.set(i, 1, 'test'+i);

// Save it 
workbook.save(function(ok){
  if (!ok) 
    workbook.cancel();
  else
    console.log('congratulations, your workbook created');
});

You can only match to constants in switch statements.

Example:

switch (variable1)
{
    case 1: // A hard-coded value
        // Code
        break;
    default:
        // Code
        break;
}

Successful!

switch (variable1)
{
    case variable2:
        // Code
        break;
    default:
        // Code
        break;
}

CS0150 A constant value is expected.

As it solved the problem, I put it as an answer.

Don't use single and double quotes, especially when you define a raw string with r in front of it.

The correct call is then

path = r"C:\Apps\CorVu\DATA\Reports\AlliD\Monthly Commission Reports\Output\pdcom1"

or

path = r'C:\Apps\CorVu\DATA\Reports\AlliD\Monthly Commission Reports\Output\pdcom1'

Just use MultipleActiveResultSets=True in your connection string.

Try using:

if(NewType* v = dynamic_cast<NewType*>(old)) {
   // old was safely casted to NewType
   v->doSomething();
}

This requires your compiler to have rtti support enabled.

EDIT: I've had some good comments on this answer!

Every time you need to use a dynamic_cast (or instanceof) you'd better ask yourself whether it's a necessary thing. It's generally a sign of poor design.

Typical workarounds is putting the special behaviour for the class you are checking for into a virtual function on the base class or perhaps introducing something like a visitor where you can introduce specific behaviour for subclasses without changing the interface (except for adding the visitor acceptance interface of course).

As pointed out dynamic_cast doesn't come for free. A simple and consistently performing hack that handles most (but not all cases) is basically adding an enum representing all the possible types your class can have and check whether you got the right one.

if(old->getType() == BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

This is not good oo design, but it can be a workaround and its cost is more or less only a virtual function call. It also works regardless of RTTI is enabled or not.

Note that this approach doesn't support multiple levels of inheritance so if you're not careful you might end with code looking like this:

// Here we have a SpecialBox class that inherits Box, since it has its own type
// we must check for both BOX or SPECIAL_BOX
if(old->getType() == BOX || old->getType() == SPECIAL_BOX) {
   Box* box = static_cast<Box*>(old);
   // Do something box specific
}

if you want to get the data in the entire row, you can use this combination below

tableModel.getDataVector().elementAt(jTable.getSelectedRow());

Where "tableModel" is the model for the table that can be accessed like so

(DefaultTableModel) jTable.getModel();

this will return the entire row data.

I hope this helps somebody

How about?

DF$Den<-ifelse (is.na(DF$Denial1) | is.na(DF$Denial2) | is.na(DF$Denial3), "0", "1")

Firstly, I don't think spaces for an id is valid.

So i'd change the id to not include spaces.

<label year="2010" month="6" id="currentMonth"> June &nbsp;2010</label>

then the jquery code is simple (keep in mind, its better to fetch the jquery object once and use over and over agian)

var label = $('#currentMonth');
var month = label.attr('month');
var year = label.attr('year');
var text = label.text();

It can be done with CSS only, no javascript at all : running demo

1. Apply a custom HTML attribute, eg. data-tooltip="bla bla" to your object (div or whatever):

   <div data-tooltip="bla bla">
       something here
   </div>
   

2. Define the :before pseudoelement of each [data-tooltip] object to be transparent, absolutely positioned and with data-tooltip="" value as content:

   [data-tooltip]:before {            
       position : absolute;
        content : attr(data-tooltip);
        opacity : 0;
   }
   

3. Define :hover:before hovering state of each [data-tooltip] to make it visible:

   [data-tooltip]:hover:before {        
       opacity : 1;
   }
   

4. Apply your styles (color, size, position etc) to the tooltip object; end of the story.

In the demo I've defined another rule to specify if the tooltip must disappear when hovering over it but outside of the parent, with another custom attribute, data-tooltip-persistent, and a simple rule:

[data-tooltip]:not([data-tooltip-persistent]):before {
    pointer-events: none;
}

Note 1: The browser coverage for this is very wide, but consider using a javascript fallback (if needed) for old IE.

Note 2: an enhancement might be adding a bit of javascript to calculate the mouse position and add it to the pseudo elements, by changing a class applied to it.

I got this error when I did a Response.Redirect after a successful login of the user.

I fixed it by doing a FormsAuthentication.RedirectFromLoginPage instead.

The answer depends on specifically what you mean by the "top 1000 distinct" records.

If you mean that you want to return at most 1000 distinct records, regardless of how many duplicates are in the table, then write this:

SELECT DISTINCT TOP 1000 id, uname, tel
FROM Users
ORDER BY <sort_columns>

If you only want to search the first 1000 rows in the table, and potentially return much fewer than 1000 distinct rows, then you would write it with a subquery or CTE, like this:

SELECT DISTINCT *
FROM
(
    SELECT TOP 1000 id, uname, tel
    FROM Users
    ORDER BY <sort_columns>
) u

The ORDER BY is of course optional if you don't care about which records you return.

I would use TreeMap, which implements SortedMap. It is designed exactly for that.

Example:

Map<Integer, String> map = new TreeMap<Integer, String>();

// Add Items to the TreeMap
map.put(1, "One");
map.put(2, "Two");
map.put(3, "Three");

// Iterate over them
for (Map.Entry<Integer, String> entry : map.entrySet()) {
    System.out.println(entry.getKey() + " => " + entry.getValue());
}

See the Java tutorial page for SortedMap.
And here a list of tutorials related to TreeMap.

It will be:

UTF8

See here for the definitions.

In your Laravel deployment it would be

/vendor/laravel/framework/src/Illuminate/Foundation/Application.php

to see who changed your Laravel version look at what's defined in composer.json. If you have "laravel/framework": "5.4.*", then it will update to the latest after composer update is run. Composer.lock is the file that results from running a composer update, so really see who last one to modify the composer.json file was (hopefully you have that in version control). You can read more about it here https://getcomposer.org/doc/01-basic-usage.md

In case the container is already running:

docker exec -it container_id_or_name ash

Use this:

var dict = list.ToDictionary(x => x);

See MSDN for more info.

As Pranay points out in the comments, this will fail if an item exists in the list multiple times.
Depending on your specific requirements, you can either use var dict = list.Distinct().ToDictionary(x => x); to get a dictionary of distinct items or you can use ToLookup instead:

var dict = list.ToLookup(x => x);

This will return an ILookup<string, string> which is essentially the same as IDictionary<string, IEnumerable<string>>, so you will have a list of distinct keys with each string instance under it.

I had the same option and as soon as I turned off Instant run, it worked fine on my API16 device, but on the API24 device it worked fine with Instant run.

Hope this helps someone having the same issue

Have you tried?

var isoDateTimeFormat = CultureInfo.InvariantCulture.DateTimeFormat;

// "2013-10-10T22:10:00"
 dateValue.ToString(isoDateTimeFormat.SortableDateTimePattern); 

// "2013-10-10 22:10:00Z"    
dateValue.ToString(isoDateTimeFormat.UniversalSortableDateTimePattern)

Also try using parameters when you store the c# datetime value in the mySql database, this might help.

Try this,

alter table goods add column `id` int(10) unsigned primary key auto_increment

I know this is a very old question, but I've been asked by someone else something similar.

I don't have TeraData, but can't you do the following?

SELECT employee_number,
       course_code,
       MAX(course_completion_date)                                     AS max_course_date,
       MAX(course_completion_date) OVER (PARTITION BY employee_number) AS max_date
FROM employee_course_completion
WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code

The GROUP BY now ensures one row per course per employee. This means that you just need a straight MAX() to get the max_course_date.

Before your GROUP BY was just giving one row per employee, and the MAX() OVER() was trying to give multiple results for that one row (one per course).

Instead, you now need the OVER() clause to get the MAX() for the employee as a whole. This is now legitimate because each individual row gets just one answer (as it is derived from a super-set, not a sub-set). Also, for the same reason, the OVER() clause now refers to a valid scalar value, as defined by the GROUP BY clause; employee_number.

Perhaps a short way of saying this would be that an aggregate with an OVER() clause must be a super-set of the GROUP BY, not a sub-set.

Create your query with a GROUP BY at the level that represents the rows you want, then specify OVER() clauses if you want to aggregate at a higher level.

It looks like you're having a permissions error, based on this message in your output: error: could not create '/lib/python2.7/site-packages/lxml': Permission denied.

One thing you can try is doing a user install of the package with pip install lxml --user. For more information on how that works, check out this StackOverflow answer. (Thanks to Ishaan Taylor for the suggestion)

You can also run pip install as a superuser with sudo pip install lxml but it is not generally a good idea because it can cause issues with your system-level packages.

Simply we can format the date like,

var month = date.getMonth() + 1;
var day = date.getDate();
var date1 = (('' + day).length < 2 ? '0' : '') + day + '/' + (('' + month).length < 2 ? '0' : '') + month + '/' + date.getFullYear();
$("#txtDate").val($.datepicker.formatDate('dd/mm/yy', new Date(date1)));

Where "date" is a date in any format.

No, you don't it's enough to do something like this:

<ul class="clearfix">
  <li>one</li>
  <li>two></li>
</ul>

And the following CSS:

ul li {float: left;}


.clearfix:after {
  content: ".";
  display: block;
  clear: both;
  visibility: hidden;
  line-height: 0;
  height: 0;
}

.clearfix {
  display: inline-block;
}

html[xmlns] .clearfix {
   display: block;
}

* html .clearfix {
   height: 1%;
}

Two possible situations :

• Your company uses a proxy to connect to the public Maven repository. Then ask someone in your company what the IP address of the proxy is then put it in your settings.xml file

• Your company has its/their own Maven repository/ies (Nexus repository for example). Then ask someone in your company what the Nexus repository is then put it in your pom.xml or in your settings.xml. See Adding maven nexus repo to my pom.xml and https://maven.apache.org/guides/mini/guide-multiple-repositories.html

Your command line should have a -d/--data inserted before the string you want to send in the PUT, and you want to set the Content-Type and not Accept.

curl -H 'Content-Type: application/json' -X PUT -d '[JSON]' \
     http://example.com/service

Using the exact JSON data from the question, the full command line would become:

curl -H 'Content-Type: application/json' -X PUT \
    -d '{"tags":["tag1","tag2"],
         "question":"Which band?",
         "answers":[{"id":"a0","answer":"Answer1"},
                    {"id":"a1","answer":"answer2"}]}' \
    http://example.com/service

Note: JSON data wrapped only for readability, not valid for curl request.

Here is my solution:

chrome.runtime.onMessage.addListener(function(request, sender) {
        if (request.action == "getSource") {
            this.pageSource = request.source;
            var title = this.pageSource.match(/<title[^>]*>([^<]+)<\/title>/)[1];
            alert(title)
        }
    });

    chrome.tabs.query({ active: true, currentWindow: true }, tabs => {
        chrome.tabs.executeScript(
            tabs[0].id,
            { code: 'var s = document.documentElement.outerHTML; chrome.runtime.sendMessage({action: "getSource", source: s});' }
        );
    });

You cannot test for string[] in the general case but you can test for Array quite easily the same as in JavaScript https://stackoverflow.com/a/767492/390330

If you specifically want for string array you can do something like:

if (Array.isArray(value)) {
   var somethingIsNotString = false;
   value.forEach(function(item){
      if(typeof item !== 'string'){
         somethingIsNotString = true;
      }
   })
   if(!somethingIsNotString && value.length > 0){
      console.log('string[]!');
   }
}

I think you already listed the best practice and that is NOT to use it unless REALLY necessary. I would strongly recommend looking at your code in more detail, using profiling tools potentially if needed to answer these questions first.

1. Do you have something in your code that is declaring items at a larger scope than needed
2. Is the memory usage really too high
3. Compare performance before and after using GC.Collect() to see if it really helps.

D:/bfs_ENTW_deb/obj/test/main_filesystem.obj:main_filesystem.cpp:(.text+0x54): undefined reference to `boost::system::generic_category()

Solution was to use the debug-version of the system-lib:

g++ -mconsole -Wl,--export-all-symbols -LC:/Programme/CPP-Entwicklung/MinGW-4.5.2/lib  -LD:/bfs_ENTW_deb/lib   -static-libgcc -static-libstdc++ -LC:/Programme/CPP-Entwicklung/boost_1_47_0/stage/lib   \

But why?

You can try out

ThisWorkbook.Save
ThisWorkbook.Saved = True
Application.Quit

This should do it:

cat ~/Desktop/myfile.txt | sed s/:/\\n/g

Make sure you verify your setting for "Prefer 32-bit". In my case Visual Studio 2012 had this setting checked by default. Trying to use anything from an external DLL failed until I unchecked "Prefer 32-bit".

As mentioned by few users, below code can help find all the fields in a given class.

TestClass testObject= new TestClass().getClass();
Method[] methods = testObject.getMethods();
for (Method method:methods)
{
    String name=method.getName();
    if(name.startsWith("get"))
    {
        System.out.println(name.substring(3));
    }else if(name.startsWith("is"))
    {
        System.out.println(name.substring(2));
    }
}

However a more interesting approach is below:

With the help of Jackson library, I was able to find all class properties of type String/integer/double, and respective values in a Map class. (without using reflections api!)

TestClass testObject = new TestClass();
com.fasterxml.jackson.databind.ObjectMapper m = new com.fasterxml.jackson.databind.ObjectMapper();

Map<String,Object> props = m.convertValue(testObject, Map.class);

for(Map.Entry<String, Object> entry : props.entrySet()){
    if(entry.getValue() instanceof String || entry.getValue() instanceof Integer || entry.getValue() instanceof Double){
        System.out.println(entry.getKey() + "-->" + entry.getValue());
    }
}

You can also specify columns on related model at the time of accessing it.

Post::first()->user()->get(['columns....']);

for multiple classes situation, as @jbojcic mentioned above, you can use:

host: {class: 'A B C'}

Sounds like an error you would get when your forms authentication ticket has expired. What is the timeout period for your ticket? Is it set to sliding or absolute expiration?

I believe the default for the timeout is 20 minutes with sliding expiration so if a user gets authenticated and at some point doesn't hit your site for 20 minutes their ticket would be expired. If it is set to absolute expiration it will expire X number of minutes after it was issued where X is your timeout setting.

You can set the timeout and expiration policy (e.g. sliding, absolute) in your web/machine.config under /configuration/system.web/authentication/forms

Your other options include:

• SimplePie
• Last RSS
• PHP Universal Feed Parser

For us, everything was fine, emails are very small and not a lot of them are sent and sudently it gave this error. It appeared that a technicien installed ASTARO which was preventing email to be sent. and we were getting this error so yes the error is a bit cryptic but I hope this could help others.

Example with primitive array:

public static void permute(int[] intArray, int start) {
    for(int i = start; i < intArray.length; i++){
        int temp = intArray[start];
        intArray[start] = intArray[i];
        intArray[i] = temp;
        permute(intArray, start + 1);
        intArray[i] = intArray[start];
        intArray[start] = temp;
    }
    if (start == intArray.length - 1) {
        System.out.println(java.util.Arrays.toString(intArray));
    }
}

public static void main(String[] args){
    int intArr[] = {1, 2, 3};
    permute(intArr, 0);
}

I'm not sure what you mean by a string that contains binary numbers. But for reversing a string (or any STL-compatible container), you can use std::reverse(). std::reverse() operates in place, so you may want to make a copy of the string first:

#include <algorithm>
#include <iostream>
#include <string>

int main()
{
    std::string foo("foo");
    std::string copy(foo);
    std::cout << foo << '\n' << copy << '\n';

    std::reverse(copy.begin(), copy.end());
    std::cout << foo << '\n' << copy << '\n';
}

JSON.stringify's third parameter defines white-space insertion for pretty-printing. It can be a string or a number (number of spaces). Node can write to your filesystem with fs. Example:

var fs = require('fs');

fs.writeFile('test.json', JSON.stringify({ a:1, b:2, c:3 }, null, 4));
/* test.json:
{
     "a": 1,
     "b": 2,
     "c": 3,
}
*/

See the JSON.stringify() docs at MDN, Node fs docs

There are plenty of wonderful answers here already, but I wanted to throw in 1 more option for those wanting to add a new column to the original dataset that contains the number of times that row is repeated.

df1$counts <- sapply(X = paste(df1$Year, df1$Month), 
                     FUN = function(x) { sum(paste(df1$Year, df1$Month) == x) })

The same could be accomplished by combining any of the above answers with the merge() function.

With the first example, SetPrivateValue won't exist in the build if DEBUG is not defined, with the second example, calls to SetPrivateValue won't exist in the build if DEBUG is not defined.

With the first example, you'll have to wrap any calls to SetPrivateValue with #if DEBUG as well.

With the second example, the calls to SetPrivateValue will be omitted, but be aware that SetPrivateValue itself will still be compiled. This is useful if you're building a library, so an application referencing your library can still use your function (if the condition is met).

If you want to omit the calls and save the space of the callee, you could use a combination of the two techniques:

[System.Diagnostics.Conditional("DEBUG")]
public void SetPrivateValue(int value){
    #if DEBUG
    // method body here
    #endif
}

The answers here match up to the question, but I'm going to answer the question you didn't ask. "Should I use truncate or delete?" If you are removing all rows from a table, you'll typically want to truncate, since it's much much faster. Why is it much faster? At least in the case of Oracle, it resets the high water mark. This is basically a dereferencing of the data and allows the db to reuse it for something else.

string Time = "16:23:01";
DateTime date = DateTime.Parse(Time, System.Globalization.CultureInfo.CurrentCulture);

string t = date.ToString("HH:mm:ss tt");

You get this error because your variable subjects is an Object not Array, you can use map() only for Array.

In case of mapping object you can do this:

{ 
    Object.keys(subjects).map((item, i) => (
        <li className="travelcompany-input" key={i}>
            <span className="input-label">{ subjects[item].name }</span>
        </li>
    ))
}  

Since Django 2.x, on_delete is required.

Django Documentation

Deprecated since version 1.9: on_delete will become a required argument in Django 2.0. In older versions it defaults to CASCADE.

Through Configuration, you can do this:

Model1
{
    int fk_one,
    int fk_two
}

Model2
{
    int pk_one,
    int pk_two,
}

then in the context config

public class MyContext : DbContext
{
    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Entity<Model1>()
            .HasRequired(e => e.Model2)
            .WithMany(e => e.Model1s)
            .HasForeignKey(e => new { e.fk_one, e.fk_two })
            .WillCascadeOnDelete(false);
    }
}

This is built into core: See Settings ? Tab Type and choose auto:

When set to "auto", the editor auto-detects the tab type based on the contents of the buffer (it uses the first leading whitespace on a non-comment line), or uses the value of the Soft Tabs config setting if auto-detection fails.

You may also want to take a look at the Auto Detect Indentation package. From the docs:

Automatically detect indentation of opened files. It looks at each opened file and sets file specific tab settings (hard/soft tabs, tab length) based on the content of the file instead of always using the editor defaults.

You might have atom configured to use 4 spaces for tabs but open a rails project which defaults to 2 spaces. Without this package, you would have to change your tabstop settings globally or risk having inconsistent lead spacing in your files.

Several answers show dangerous examples. OP's example [ $a == $b ] specifically used unquoted variable substitution (as of Oct '17 edit). For [...] that is safe for string equality.

But if you're going to enumerate alternatives like [[...]], you must inform also that the right-hand-side must be quoted. If not quoted, it is a pattern match! (From bash man page: "Any part of the pattern may be quoted to force it to be matched as a string.").

Here in bash, the two statements yielding "yes" are pattern matching, other three are string equality:

$ rht="A*"
$ lft="AB"
$ [ $lft = $rht ] && echo yes
$ [ $lft == $rht ] && echo yes
$ [[ $lft = $rht ]] && echo yes
yes
$ [[ $lft == $rht ]] && echo yes
yes
$ [[ $lft == "$rht" ]] && echo yes
$

The book HTML5 Guidelines for Web Developers: Structure and Semantics for Documents suggested this way (option 1):

<aside id="sidebar">
    <section id="widget_1"></section>
    <section id="widget_2"></section>
    <section id="widget_3"></section>
</aside>

It also points out that you can use sections in the footer. So section can be used outside of the actual page content.

I don't know why all the answers over here are so confusing. I found a quite simpler one. Use a css class for the asp:menu, say, mainMenu and all the menu items under this will be "a tags" when rendered into HTML. So you just have to provide :hover property to those "a tags" in your CSS. See below for the example:

<asp:Menu ID="mnuMain" Orientation="Horizontal" runat="server" Font-Bold="True" Width="100%" CssClass="mainMenu">
  <Items>
    <asp:MenuItem Text="Home"></asp:MenuItem>
    <asp:MenuItem Text="About Us"></asp:MenuItem>
  </Items>
</asp:Menu>

And in the CSS, write:

.mainMenu { background:#900; }
.mainMenu a { color:#fff; }
.mainMenu a:hover { background:#c00; color:#ff9; }

I hope this helps. :)

We can assign any command to any action(given) in Eclipse From Menu Bar go to Window > Preferences then search for the keys then search copy line then click on copy line and then click on command in Binding and peform a command which you wish to use for duplicating line i use ctrl+shift+d you can choose whatever you want

If you have (or create) a single string, you can use np.fromstring:

import numpy as np
x = ["1.1", "2.2", "3.2"]
x = ','.join(x)
x = np.fromstring( x, dtype=np.float, sep=',' )

Note, x = ','.join(x) transforms the x array to string '1.1, 2.2, 3.2'. If you read a line from a txt file, each line will be already a string.

You could use Twitter's snowflake.

In short, it generates a unique id based on time, server id and a sequence. It generates a 64-bit value so it is pretty small and it fits in an INT64. It also allows for sorting values correctly.

https://developer.twitter.com/en/docs/basics/twitter-ids

In sum, it allows multiple servers, highly concurrency, sorting value and all of them in 64 bits.

Here it is the implementation for MySQL

https://github.com/EFTEC/snowflake-mysql

It consists of a function and a table.

Build Path -> Configure Build Path -> Libraries (Tab) -> Add Class Folder, then select your folder or create one.

Yields, to put it simply, allow the method you create to take and call blocks. The yield keyword specifically is the spot where the 'stuff' in the block will be performed.

Can't be done natively with VBA. VBA is built in a single-threaded apartment. The only way to get multiple threads is to build a DLL in something other than VBA that has a COM interface and call it from VBA.

INFO: Descriptions and Workings of OLE Threading Models

Sort of:

class some_class {
    static std::vector<std::string> v; // declaration
};

const char *vinit[] = {"one", "two", "three"};

std::vector<std::string> some_class::v(vinit, end(vinit)); // definition

end is just so I don't have to write vinit+3 and keep it up to date if the length changes later. Define it as:

template<typename T, size_t N>
T * end(T (&ra)[N]) {
    return ra + N;
}

You can merge multiple modules in one rootModule , and assign that module as ng-app to a superior element ex: body tag.

code ex:

<script src="namesController.js"></script>

<body ng-app="rootApp">

<div ng-app="myApp1" ng-controller="myCtrl" >
First Name: <input type="text" ng-model="firstName"><br>
Last Name: <input type="text" ng-model="lastName"><br>
<br>
Full Name: {{firstName + " " + lastName}}
</div>

<div ng-app="myApp2" ng-controller="namesCtrl">

In case this error came from a web server: Try url encoding your post value. I was POSTing via "curl" and discovered I wasn't url-encoding my base64 value so characters like "+" were not escaped so the web server url-decode logic automatically ran url-decode and converted + to spaces.

"+" is a valid base64 character and perhaps the only character which gets mangled by an unexpected url-decode.

I got this when I didn't type things right. I had

__init.py__ 

instead of

__init__.py

While generating the links set the target to the iframes name property and you probably wont have to deal with jquery at all.

<a href="inventory.aspx" target="contentframe"  title="Title Inventory">
<iframe id="iframe1" name="contentframe"  ></iframe>

1.Go to your manifest.xml file.

2.Find the activity tag for which you want to hide your ActionBar and then add ,

android:theme="@style/Theme.AppCompat.NoActionBar"

           <activity
            android:name=".MainActivity"
            android:theme="@style/Theme.AppCompat.NoActionBar"
            >

 string c = Char.ConvertFromUtf32(65);

c will contain "A"

Assuming that you don't have a library or system header that defines NULL as for example (void*)0 or (char*)0 it's fine. I always tend to use 0 myself as it is by definition the null pointer. In c++0x you'll have nullptr available so the question won't matter as much anymore.

Option 1: Likely fastest (but not supported by some browsers if used on Document or SVGElement) :

var elements = document.getElementById('parentContainer').children;

Option 2: Likely slowest :

var elements = document.getElementById('parentContainer').getElementsByTagName('*');

Option 3: Requires change to code (wrap a form instead of a div around it) :

// Since what you're doing looks like it should be in a form...
var elements = document.forms['parentContainer'].elements;

var matches = [];

for (var i = 0; i < elements.length; i++)
    if (elements[i].value.indexOf('q17_') == 0)
        matches.push(elements[i]);

use OutputStream instead of FileWriter to set encoding type

// file is your File object where you want to write you data 
OutputStream outputStream = new FileOutputStream(file);
OutputStreamWriter outputStreamWriter = new OutputStreamWriter(outputStream, "UTF-8");
outputStreamWriter.write(json); // json is your data 
outputStreamWriter.flush();
outputStreamWriter.close();

(current / maximum) * 100. In your case, (2 / 10) * 100.

You can either use tsc --declaration fileName.ts like Ryan describes, or you can specify declaration: true under compilerOptionsin your tsconfig.json assuming you've already had a tsconfig.json under your project.

There are a couple of things that need to be adjusted in your layout:

1. You are nesting col elements within form-group elements. This should be the other way around (the form-group should be within the col-sm-xx element).

2. You should always use a row div for each new "row" in your design. In your case, you would need at least 5 rows (Username, Password and co, Title/First/Last name, email, Language). Otherwise, your problematic .col-sm-12 is still on the same row with the above 3 .col-sm-4 resulting in a total of columns greater than 12, and causing the overlap problem.

Here is a fixed demo.

And an excerpt of what the problematic section HTML should become:

<fieldset>
    <legend>Personal Information</legend>
    <div class='row'>
        <div class='col-sm-4'>    
            <div class='form-group'>
                <label for="user_title">Title</label>
                <input class="form-control" id="user_title" name="user[title]" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_firstname">First name</label>
                <input class="form-control" id="user_firstname" name="user[firstname]" required="true" size="30" type="text" />
            </div>
        </div>
        <div class='col-sm-4'>
            <div class='form-group'>
                <label for="user_lastname">Last name</label>
                <input class="form-control" id="user_lastname" name="user[lastname]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
    <div class='row'>
        <div class='col-sm-12'>
            <div class='form-group'>

                <label for="user_email">Email</label>
                <input class="form-control required email" id="user_email" name="user[email]" required="true" size="30" type="text" />
            </div>
        </div>
    </div>
</fieldset>

The ENABLEDELAYEDEXPANSION part is REQUIRED in certain programs that use delayed expansion, that is, that takes the value of variables that were modified inside IF or FOR commands by enclosing their names in exclamation-marks.

If you enable this expansion in a script that does not require it, the script behaves different only if it contains names enclosed in exclamation-marks !LIKE! !THESE!. Usually the name is just erased, but if a variable with the same name exist by chance, then the result is unpredictable and depends on the value of such variable and the place where it appears.

The SETLOCAL part is REQUIRED in just a few specialized (recursive) programs, but is commonly used when you want to be sure to not modify any existent variable with the same name by chance or if you want to automatically delete all the variables used in your program. However, because there is not a separate command to enable the delayed expansion, programs that require this must also include the SETLOCAL part.

You need to use a textarea to get multiline handling.

<textarea name="Text1" cols="40" rows="5"></textarea>

It's probably not anywhere approaching a best practice, but I usually call a SIZE on the collection to load the children in the same transaction, like you have suggested. It's clean, immune to any changes in the structure of the child elements, and yields SQL with low overhead.

you are missing the "btn btn-navbar" section. For example:

        <a class="btn btn-navbar" data-toggle="collapse" data-target=".nav-collapse">
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
            <span class="icon-bar"></span>
        </a>

Take a look to navbar documentation in:

Twitter Bootstrap

this bellow code gave me correct response

jar cvf MyJar.jar *.properties lib/*.jar -C bin .  

it added the (log4j) properties file, it added the jar files in lib. and then it went inside bin to retrieve the class files with package.

as of now, you can use

<img src="{{ asset('images/foo.png') }}" alt="tag">

Although I'm not answering the original question concering the no-op command, many (if not most) problems when one may think "in this branch I have to do nothing" can be bypassed by simply restructuring the logic so that this branch won't occur.

I try to give a general rule by using the OPs example

do nothing when $a is greater than "10", print "1" if $a is less than "5", otherwise, print "2"

we have to avoid a branch where $a gets more than 10, so $a < 10 as a general condition can be applied to every other, following condition.

In general terms, when you say do nothing when X, then rephrase it as avoid a branch where X. Usually you can make the avoidance happen by simply negating X and applying it to all other conditions.

So the OPs example with the rule applied may be restructured as:

if [ "$a" -lt 10 ] && [ "$a" -le 5 ]
then
    echo "1"
elif [ "$a" -lt 10 ]
then
    echo "2"
fi

Just a variation of the above, enclosing everything in the $a < 10 condition:

if [ "$a" -lt 10 ]
then
    if [ "$a" -le 5 ]
    then
        echo "1"
    else
        echo "2"
    fi
fi

(For this specific example @Flimzys restructuring is certainly better, but I wanted to give a general rule for all the people searching how to do nothing.)

You would need to attach your click event to some element. If there are lots of other elements on the page you would not want to attach a click event to all of them.

One potential way would be to create a transparent div below your dropdown menu but above all other elements on the page. You would show it when the drop down was shown. Have the element have a click hander that hides the drop down and the transparent div.

$('#clickCatcher').click(function () { _x000D_
  $('#dropContainer').hide();_x000D_
  $(this).hide();_x000D_
});

#dropContainer { z-index: 101; ... }_x000D_
#clickCatcher { position: absolute; top: 0; left: 0; width: 100%; height: 100%; z-index: 100; }

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="dropDown"></div>_x000D_
<div id="clickCatcher"></div>

Ok, I know there is an accepted answer but… for more special cases you also could use this one:

array_map(function($n) { echo $n['filename']; echo $n['filepath'];},$array);

Or in a more un-complex way:

function printItem($n){
    echo $n['filename'];
    echo $n['filepath'];
}

array_map('printItem', $array);

This will allow you to manipulate the data in an easier way.

Putting @Component or @configuration in your bean config file seems to work, ie something like:

@Configuration
public class MyApplicationContext {
    @Bean
    public DirectoryScanner scanner() {
        return new WatchServiceDirectoryScanner("/tmp/myDir");
    }
}

@Component
public class MyApplicationContext {
    @Bean
    public DirectoryScanner scanner() {
        return new WatchServiceDirectoryScanner("/tmp/myDir");
    }
}

I have downloaded the datepicker from jqueryui.com/download and I got 1.7.2 version but still onSelect function didn't work. Here is what i had -

$("#datepicker").datepicker();

$("#datepicker").datepicker({ 
      onSelect: function(value, date) { 
         alert('The chosen date is ' + value); 
      } 
});

I found the solution in this page -- problem with jquery datepicker onselect . Removed the $("#datepicker").datepicker(); once and it worked.

I have a code very similar to yours and if it works onPause () and onResume (). When changing the fragment, these functions are activated respectively.

Code in fragment:

 @Override
public void onResume() {
    super.onResume();
    sensorManager.registerListener(this, proximidad, SensorManager.SENSOR_DELAY_NORMAL);
    sensorManager.registerListener(this, brillo, SensorManager.SENSOR_DELAY_NORMAL);
    Log.e("Frontales","resume");
}

@Override
public void onPause() {
    super.onPause();
    sensorManager.unregisterListener(this);
    Log.e("Frontales","Pause");

}

Log when change of fragment:

05-19 22:28:54.284 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:28:57.002 2371-2371/madi.cajaherramientas E/Frontales: Pause
05-19 22:28:58.697 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:29:00.840 2371-2371/madi.cajaherramientas E/Frontales: Pause
05-19 22:29:02.248 2371-2371/madi.cajaherramientas E/Frontales: resume
05-19 22:29:03.718 2371-2371/madi.cajaherramientas E/Frontales: Pause

Fragment onCreateView:

View rootView;
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {

    rootView = inflater.inflate(R.layout.activity_proximidad, container, false);
    ButterKnife.bind(this,rootView);
    inflar();
    setTextos();
    return rootView;
}

Action when I pulse back (in the activity where I load the fragment):

@Override
public void onBackPressed() {

    int count = getFragmentManager().getBackStackEntryCount();

    if (count == 0) {
        super.onBackPressed();

    } else {
        getFragmentManager().popBackStack();
    }

 }

After reading all the answers here - how to summarize grouped information, i decided to skip it all and just loaded one of the SQL javascript libraries. I'm using alasql, yeah it takes a few secs longer on load time but saves countless time in coding and debugging, Now to group and sum() I just use,

$scope.bySchool = alasql('SELECT School, SUM(Cost) AS Cost from ? GROUP BY School',[restResults]);

I know this sounds like a bit of a rant on angular/js but really SQL solved this 30+ years ago and we shouldn't have to re-invent it within a browser.

Not enough reputation to comment yet so I'll just put this here:

To expand on Micah's answer - the browser runs your code top to bottom, so if you write:

<div id="chart"></div>
<script>var svg = d3.select("#chart").append("svg:svg");</script>

The browser will create a div with id "chart", and then run your script, which will try to find that div, and, hurray, success.

Otherwise if you write:

<script>var svg = d3.select("#chart").append("svg:svg");</script>
<div id="chart"></div>

The browser runs your script, and tries to find a div with id chart, but it hasn't been created yet so it fails.

THEN the browser creates a div with id "chart".

I would recommend setting the HR itself to be 0px high and use its border to be visible instead. I have noticed that when you zoom in and out (ctrl + mouse wheel) the thickness of HR itself changes, while when you set the border it always stays the same:

hr {
    height: 0px;
    border: none;
    border-top: 1px solid black;
}

The reason it invokes the method immediately and pressing the button does nothing is that action(somenumber) is evaluated and its return value is attributed as the command for the button. So if action prints something to tell you it has run and returns None, you just run action to evaluate its return value and given None as the command for the button.

To have buttons to call functions with different arguments you can use global variables, although I can't recommend it:

import Tkinter as Tk

frame = Tk.Frame(width=5, height=2, bd=1, relief=Tk.SUNKEN)
frame.grid(row=2,column=2)
frame.pack(fill=Tk.X, padx=5, pady=5)
def action():
    global output
    global variable
    output.insert(Tk.END,variable.get())
button = Tk.Button(master=frame, text='press', command=action)
button.pack()
variable = Tk.Entry(master=frame)
variable.pack()
output = Tk.Text(master=frame)
output.pack()

if __name__ == '__main__':
    Tk.mainloop()

What I would do is make a class whose objects would contain every variable required and methods to change those as needed:

import Tkinter as Tk
class Window:
    def __init__(self):
        self.frame = Tk.Frame(width=5, height=2, bd=1, relief=Tk.SUNKEN)
        self.frame.grid(row=2,column=2)
        self.frame.pack(fill=Tk.X, padx=5, pady=5)

        self.button = Tk.Button(master=self.frame, text='press', command=self.action)
        self.button.pack()

        self.variable = Tk.Entry(master=self.frame)
        self.variable.pack()

        self.output = Tk.Text(master=self.frame)
        self.output.pack()

    def action(self):
        self.output.insert(Tk.END,self.variable.get())

if __name__ == '__main__':
    window = Window()
    Tk.mainloop()

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

One more advantage:
As you know that Java doesn't support multiple inheritance, so if you use "Thread" kinda class as anonymous class then the class still has one space left for any other class to extend.

You didn't paste the part where you call startActivity, that's the interesting part.

You might be calling startActivity in a Service context, or in an Application context.

Print "this" to log cat before making the startActivity call, and see what it refers to, it's sometimes a case of using an inner "this" accidentally.

If you really don't have a choice for refactoring you can mock/stub everything in the super method call e.g.

    class BaseService {

        public void validate(){
            fail(" I must not be called");
        }

        public void save(){
            //Save method of super will still be called.
            validate();
        }
    }

    class ChildService extends BaseService{

        public void load(){}

        public void save(){
            super.save();
            load();
        }
    }

    @Test
    public void testSave() {
        ChildService classToTest = Mockito.spy(new ChildService());

        // Prevent/stub logic in super.save()
        Mockito.doNothing().when((BaseService)classToTest).validate();

        // When
        classToTest.save();

        // Then
        verify(classToTest).load();
    }

Another way based on amadan:

    SELECT * FROM [Purchasing].[Vendor] WHERE  

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

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

It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.

Simply copy your script and put under """ your entire code """ ...

specify this line in a variable.. like,

a = """ your entire code """
print a.replace('    ','    ') # first 4 spaces tab second four space from space bar

print a.replace('here please press tab button it will insert some space"," here simply press space bar four times")
# here we replacing tab space by four char space as per pep 8 style guide..

now execute this code, in sublime using ctrl+b, now it will print indented code in console. that's it

Navigate to the "Get just the command line tools" section of the android downloads page, and download the tools for your system.

For Windows:

Extract the contents to C:\Android\android-sdk

Navigate to C:\Android\android-sdk\tools\bin and open a command line window
(shift + right click)

Run the following to download the latest android package:

sdkmanager "platforms;android-25" 

Update everything

sdkmanager --update

Other operation systems Do pretty much the same, but not using windows directories.

The sdkmanager page gives more info in to what commands to use to install your sdk.

I've seen some very creative answers, but you can just do this (for global packages add the --global switch):

npm ls package

Example:

npm ls babel-cli
`-- [email protected]

The npm documentation says that npm -ls

This command will print to stdout all the versions of packages that are installed, as well as their dependencies, in a tree-structure.

NPM documentation

Though @Test(expected = MyException.class) and the ExpectedException rule are very good choices, there are some instances where the JUnit3-style exception catching is still the best way to go:

@Test public void yourTest() {
  try {
    systemUnderTest.doStuff();
    fail("MyException expected.");
  } catch (MyException expected) {

    // Though the ExpectedException rule lets you write matchers about
    // exceptions, it is sometimes useful to inspect the object directly.

    assertEquals(1301, expected.getMyErrorCode());
  }

  // In both @Test(expected=...) and ExpectedException code, the
  // exception-throwing line will be the last executed line, because Java will
  // still traverse the call stack until it reaches a try block--which will be
  // inside the JUnit framework in those cases. The only way to prevent this
  // behavior is to use your own try block.

  // This is especially useful to test the state of the system after the
  // exception is caught.

  assertTrue(systemUnderTest.isInErrorState());
}

Another library that claims to help here is catch-exception; however, as of May 2014, the project appears to be in maintenance mode (obsoleted by Java 8), and much like Mockito catch-exception can only manipulate non-final methods.

You can use this tool to create appropriate c# classes:

http://jsonclassgenerator.codeplex.com/

and when you will have classes created you can simply convert string to object:

    public static T ParseJsonObject<T>(string json) where T : class, new()
    {
        JObject jobject = JObject.Parse(json);
        return JsonConvert.DeserializeObject<T>(jobject.ToString());
    }

Here that classes: http://ge.tt/2KGtbPT/v/0?c

Just fix namespaces.

Compiler shows following error :

Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: 'Storyboard (<UIStoryboard: 0x7fedf2d5c9a0>) doesn't contain a 
ViewController with identifier 'SBAddEmployeeVC''

Here the object of the storyboard created is not the main storyboard which contains our ViewControllers. As storyboard file on which we work is named as Main.storyboard. So we need to have reference of object of the Main.storyboard.

Use following code for that :

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:[NSBundle mainBundle]];

Here storyboardWithName is the name of the storyboard file we are working with and bundle specifies the bundle in which our storyboard is (i.e. mainBundle).

Another way to handle single and double quotes is:

function mssql_escape($str)
{
    if(get_magic_quotes_gpc())
    {
        $str = stripslashes($str);
    }
    return str_replace("'", "''", $str);
}

C# Controller:

var result = await _roleManager.CreateAsync(identityRole);
   if (result.Succeeded == true)
       TempData["roleCreateAlert"] = "Added record successfully";

Razor Page:

@if (TempData["roleCreateAlert"] != null)
{
    <div class="alert alert-success">
        <a href="#" class="close" data-dismiss="alert" aria-label="close">×</a>
        <p>@TempData["roleCreateAlert"]</p>
    </div>
}

Any Alert Auto Close:

<script type="text/javascript">
    $(".alert").delay(5000).slideUp(200, function () {
        $(this).alert('close');
    });
</script>

You could simply use:

select {
    border: none;
    outline: none;
    scroll-behavior: smooth;
}

As the drop down list border is non editable you can not do anything with that but surely this will fix your initial outlook.

The function you posted is just not PHP.

Have a look at is_float ^[docs].

Edit: I missed the "user entered value" part. In this case you can actually use a regular expression:

^\d+\.\d+$

I use Privoxy and cURL to scrape Tor pages:

<?php
    $ch = curl_init('http://jhiwjjlqpyawmpjx.onion'); // Tormail URL
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, 1);
    curl_setopt($ch, CURLOPT_PROXY, "localhost:8118"); // Default privoxy port
    curl_setopt($ch, CURLOPT_PROXYTYPE, CURLPROXY_HTTP);
    curl_exec($ch);
    curl_close($ch);
?>

After installing Privoxy you need to add this line to the configuration file (/etc/privoxy/config). Note the space and '.' a the end of line.

forward-socks4a / localhost:9050 .

Then restart Privoxy.

/etc/init.d/privoxy restart

Please show more of your code.

If that last piece of code declares and initializes the list variable outside the loop you're basically reusing the same list object, thus adding everything into one list.

Also show where .Capacity and .Count comes into play, how did you get those values?

Set them so that their flex-basis is 0 (so all elements have the same starting point), and allow them to grow:

flex: 1 1 0px

Your IDE or linter might mention that the unit of measure 'px' is redundant. If you leave it out (like: flex: 1 1 0), IE will not render this correctly. So the px is required to support Internet Explorer, as mentioned in the comments by @fabb;

Why don't you use PowerShell?

Stop-Process -Name notepad

And if you are in a batch file:

powershell -Command "Stop-Process -Name notepad"
powershell -Command "Stop-Process -Id 4232"

Teaching to someone else who is starting to learn Python is always a great way to get your ideas clear and sometimes, I usually get a lot of neat questions from students that have me to re-think conceptual things about Python.

Redirecting from HTTP to HTTPS with PHP on IIS

I was having trouble getting redirection to HTTPS to work on a Windows server which runs version 6 of MS Internet Information Services (IIS). I’m more used to working with Apache on a Linux host so I turned to the Internet for help and this was the highest ranking Stack Overflow question when I searched for “php redirect http to https”. However, the selected answer didn’t work for me.

After some trial and error, I discovered that with IIS, $_SERVER['HTTPS'] is set to off for non-TLS connections. I thought the following code should help any other IIS users who come to this question via search engine.

<?php
if (! isset($_SERVER['HTTPS']) or $_SERVER['HTTPS'] == 'off' ) {
    $redirect_url = "https://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
    header("Location: $redirect_url");
    exit();
}
?>

Edit: From another Stack Overflow answer, a simpler solution is to check if($_SERVER["HTTPS"] != "on").

NXJSON is full-featured yet very small (~400 lines of code) JSON parser, which has easy to use API:

const nx_json* json=nx_json_parse_utf8(code);
printf("hello=%s\n", nx_json_get(json, "hello")->text_value);
const nx_json* arr=nx_json_get(json, "my-array");
int i;
for (i=0; i<arr->length; i++) {
  const nx_json* item=nx_json_item(arr, i);
  printf("arr[%d]=(%d) %ld\n", i, (int)item->type, item->int_value);
}
nx_json_free(json);

If you want to return the original string untouched if it does not contain the search character then you can use an anonymous function (a closure):

var streetaddress=(function(s){var i=s.indexOf(',');
   return i==-1 ? s : s.substr(0,i);})(addy);

This can be made more generic:

var streetaddress=(function(s,c){var i=s.indexOf(c);
   return i==-1 ? s : s.substr(0,i);})(addy,',');

Use this:

"$computer, $Speed, $Regcheck" | out-file -filepath C:\temp\scripts\pshell\dump.txt -append -width 200

print("the furnace is now " + str(temperature) + "degrees!")

cast it to str

On the ribbon,Go to Database Tools under "Show/Hide", make sure the Message bar is checked (turned on) Then click on the gray message bar, click database options. From there you can modify your security options. Just enable these types of content.

You should be good to go after this.

If you want to append to the file, open it with 'a'. If you want to seek through the file to find the place where you should insert the line, use 'r+'. (docs)

Type hints are for maintainability and don't get interpreted by Python. In the code below, the line def add(self, ic:int) doesn't result in an error until the next return... line:

class C1:
    def __init__(self):
        self.idn = 1
    def add(self, ic: int):
        return self.idn + ic

c1 = C1()
c1.add(2)

c1.add(c1)

Traceback (most recent call last):
  File "<input>", line 1, in <module>
  File "<input>", line 5, in add
TypeError: unsupported operand type(s) for +: 'int' and 'C1'

The other queries are all going base on any ONE of the conditions qualifying and it will return a record... if you want to make sure the BOTH columns of table A are matched, you'll have to do something like...

select 
      tA.Col1,
      tA.Col2,
      tB.Val
   from
      TableA tA
         join TableB tB
            on  ( tA.Col1 = tB.Col1 OR tA.Col1 = tB.Col2 )
            AND ( tA.Col2 = tB.Col1 OR tA.Col2 = tB.Col2 )

For z-index to work, you also need to give it a position:

header {
    width: 100%;
    height: 100px;
    background: url(../img/top.png) repeat-x;
    z-index: 110;
    position: relative;
}

Don't worry! This problem occurs because of the annotation. Instead of Field based access, Property based access solves this problem. The code as follows:

package onetomanymapping;

import java.util.List;

import javax.persistence.*;

@Entity
public class College {
private int collegeId;
private String collegeName;
private List<Student> students;

@OneToMany(targetEntity = Student.class, mappedBy = "college", 
    cascade = CascadeType.ALL, fetch = FetchType.EAGER)
public List<Student> getStudents() {
    return students;
}

public void setStudents(List<Student> students) {
    this.students = students;
}

@Id
@GeneratedValue
public int getCollegeId() {
    return collegeId;
}

public void setCollegeId(int collegeId) {
    this.collegeId = collegeId;
}

public String getCollegeName() {
    return collegeName;
}

public void setCollegeName(String collegeName) {
    this.collegeName = collegeName;
}

}

You definitely want to use https://github.com/niftylettuce/node-email-templates since it supports nodemailer/postmarkapp and has beautiful async email template support built-in.

Here is what I do, which is basically straight from the example(Startup) page:

## Default repo
local({r <- getOption("repos")
       r["CRAN"] <- "http://cran.r-project.org" 
       options(repos=r)
})

which is in ~/.Rprofile.

Edit: As it is now 2018, we can add that for the last few years the URL "https://cloud.r-project.org" has been preferable as it reflects a) https access and b) an "always-near-you" CDN.

You can try adding a question mark as below. This worked for me.

 componentWillReceiveProps(nextProps) {
    this.setState({
        title: nextProps?.blog?.title,
        body: nextProps?.blog?.content
     })
    }

This is my version of check ping function. May be if well be usefull for someone:

def check_ping(host):
if platform.system().lower() == "windows":
response = os.system("ping -n 1 -w 500 " + host + " > nul")
if response == 0:
return "alive"
else:
return "not alive"
else:
response = os.system("ping -c 1 -W 0.5" + host + "> /dev/null")
if response == 1:
return "alive"
else:
return "not alive"

Recently I had the same problem to include QR image/png in email. The QR image is a byte array which is generated using ZXing. We do not want to save it to a file because saving/reading from a file is too expensive (slow). So both of the answers above do not work for me. Here's what I did to solve this problem:

import javax.mail.util.ByteArrayDataSource;
import org.apache.commons.mail.ImageHtmlEmail;
...
ImageHtmlEmail email = new ImageHtmlEmail();
byte[] qrImageBytes = createQRCode(); // get your image byte array
ByteArrayDataSource qrImageDataSource = new ByteArrayDataSource(qrImageBytes, "image/png");
String contentId = email.embed(qrImageDataSource, "QR Image");

Let's say the contentId is "111122223333", then your HTML part should have this:

<img src="cid: 111122223333">

There's no need to convert the byte array to Base64 because Commons Mail does the conversion for you automatically. Hope this helps.

Standard Subversion layout

Create a git clone of that includes your Subversion trunk, tags, and branches with

git svn clone http://svn.example.com/project -T trunk -b branches -t tags

The --stdlayout option is a nice shortcut if your Subversion repository uses the typical structure:

git svn clone http://svn.example.com/project --stdlayout

Make your git repository ignore everything the subversion repo does:

git svn show-ignore >> .git/info/exclude

You should now be able to see all the Subversion branches on the git side:

git branch -r

Say the name of the branch in Subversion is waldo. On the git side, you'd run

git checkout -b waldo-svn remotes/waldo

The -svn suffix is to avoid warnings of the form

warning: refname 'waldo' is ambiguous.

To update the git branch waldo-svn, run

git checkout waldo-svn
git svn rebase

Starting from a trunk-only checkout

To add a Subversion branch to a trunk-only clone, modify your git repository's .git/config to contain

[svn-remote "svn-mybranch"]
        url = http://svn.example.com/project/branches/mybranch
        fetch = :refs/remotes/mybranch

You'll need to develop the habit of running

git svn fetch --fetch-all

to update all of what git svn thinks are separate remotes. At this point, you can create and track branches as above. For example, to create a git branch that corresponds to mybranch, run

git checkout -b mybranch-svn remotes/mybranch

For the branches from which you intend to git svn dcommit, keep their histories linear!

I have had major issues with ajax + jQuery v3 getting both the response status code and data from JSON APIs. jQuery.ajax only decodes JSON data if the status is a successful one, and it also swaps around the ordering of the callback parameters depending on the status code. Ugghhh.

The best way to combat this is to call the .always chain method and do a bit of cleaning up. Here is my code.

$.ajax({
        ...
    }).always(function(data, textStatus, xhr) {
        var responseCode = null;
        if (textStatus === "error") {
            // data variable is actually xhr
            responseCode = data.status;
            if (data.responseText) {
                try {
                    data = JSON.parse(data.responseText);
                } catch (e) {
                    // Ignore
                }
            }
        } else {
            responseCode = xhr.status;
        }

        console.log("Response code", responseCode);
        console.log("JSON Data", data);
    });

Hope this is something what you are trying to do :

import java.lang.reflect.Field;
import java.util.HashMap;
import java.util.Map;
import java.util.concurrent.ConcurrentHashMap;

public class Test {

    private Map ttp = new HashMap(); 

    public  void test() {
        Field declaredField =  null;
        try {

            declaredField = Test.class.getDeclaredField("ttp");
            boolean accessible = declaredField.isAccessible();

            declaredField.setAccessible(true);

            ConcurrentHashMap<Object, Object> concHashMap = new ConcurrentHashMap<Object, Object>();
            concHashMap.put("key1", "value1");
            declaredField.set(this, concHashMap);
            Object value = ttp.get("key1");

            System.out.println(value);

            declaredField.setAccessible(accessible);

        } catch (NoSuchFieldException 
                | SecurityException
                | IllegalArgumentException 
                | IllegalAccessException e) {
            e.printStackTrace();
        }

    }

    public static void main(String... args) {
        Test test = new Test();
        test.test(); 
    }
}

It prints :

value1

If it's a password used for authentication by your application, then hash the password as others suggest.

If you're storing passwords for an external resource, you'll often want to be able to prompt the user for these credentials and give him the opportunity to save them securely. Windows provides the Credentials UI (CredUI) for this purpose - there are a number of samples showing how to use this in .NET, including this one on MSDN.

Here is what you are looking for:

The WPF TestApi library comes with one of the nicest command line parsers for C# development. I highly recommend looking into it, from Ivo Manolov's blog on the API:

// EXAMPLE #2:
// Sample for parsing the following command-line:
// Test.exe /verbose /runId=10
// This sample declares a class in which the strongly-
// typed arguments are populated
public class CommandLineArguments
{
   bool? Verbose { get; set; }
   int? RunId { get; set; }
}

CommandLineArguments a = new CommandLineArguments();
CommandLineParser.ParseArguments(args, a);

Simpler with the aggregate function string_agg() (Postgres 9.0 or later):

SELECT movie, string_agg(actor, ', ') AS actor_list
FROM   tbl
GROUP  BY 1;

The 1 in GROUP BY 1 is a positional reference and a shortcut for GROUP BY movie in this case.

string_agg() expects data type text as input. Other types need to be cast explicitly (actor::text) - unless an implicit cast to text is defined - which is the case for all other character types (varchar, character, "char"), and some other types.

As isapir commented, you can add an ORDER BY clause in the aggregate call to get a sorted list - should you need that. Like:

SELECT movie, string_agg(actor, ', ' ORDER BY actor) AS actor_list
FROM   tbl
GROUP  BY 1;

But it's typically faster to sort rows in a subquery. See:

• Postgres SQL - Create Array in Select

As the az7ar answer is beautifully said but Let me make it simpler with socket.io rooms. request a server with a unique identifier to join a server. here we are using an email as a unique identifier.

Client Socket.io

socket.on('connect', function () {
  socket.emit('join', {email: [email protected]});
});

When the user joined a server, create a room for that user

Server Socket.io

io.on('connection', function (socket) {
   socket.on('join', function (data) {    
    socket.join(data.email);
  });
});

Now we are all set with joining. let emit something to from the server to room, so that user can listen.

Server Socket.io

io.to('[email protected]').emit('message', {msg: 'hello world.'});

Let finalize the topic with listening to message event to the client side

socket.on("message", function(data) {
  alert(data.msg);
});

The reference from Socket.io rooms

This is what I did on the controller

var collectionDate = '2002-04-26T09:00:00';
var date = new Date(collectionDate);
//then pushed all my data into an array $scope.rows which I then used in the directive

I ended up formatting the date to my desired pattern on the directive as follows.

var data = new google.visualization.DataTable();
                    data.addColumn('date', 'Dates');
                    data.addColumn('number', 'Upper Normal');
                    data.addColumn('number', 'Result');
                    data.addColumn('number', 'Lower Normal');
                    data.addRows(scope.rows);
                    var formatDate = new google.visualization.DateFormat({pattern: "dd/MM/yyyy"});
                    formatDate.format(data, 0);
//set options for the line chart
var options = {'hAxis': format: 'dd/MM/yyyy'}

//Instantiate and draw the chart passing in options
var chart = new google.visualization.LineChart($elm[0]);
                    chart.draw(data, options);

This gave me dates ain the format of dd/MM/yyyy (26/04/2002) on the x axis of the chart.

To allow https wrapper:

• the php_openssl extension must exist and be enabled
• allow_url_fopen must be set to on

In the php.ini file you should add this lines if not exists:

extension=php_openssl.dll

allow_url_fopen = On

Swift 5

Base on Fábio Oliveira's answer (https://stackoverflow.com/a/23042694/2082851), I make my own swift 4.

In short, this extension exchanges default functions init(coder:), systemFont(ofSize:), boldSystemFont(ofSize:), italicSystemFont(ofSize:) with my custom methods.

Note that it's not fully implement, but you can exchange more methods base on my implementation.

import UIKit

struct AppFontName {
    static let regular = "CourierNewPSMT"
    static let bold = "CourierNewPS-BoldMT"
    static let italic = "CourierNewPS-ItalicMT"
}

extension UIFontDescriptor.AttributeName {
    static let nsctFontUIUsage = UIFontDescriptor.AttributeName(rawValue: "NSCTFontUIUsageAttribute")
}

extension UIFont {
    static var isOverrided: Bool = false

    @objc class func mySystemFont(ofSize size: CGFloat) -> UIFont {
        return UIFont(name: AppFontName.regular, size: size)!
    }

    @objc class func myBoldSystemFont(ofSize size: CGFloat) -> UIFont {
        return UIFont(name: AppFontName.bold, size: size)!
    }

    @objc class func myItalicSystemFont(ofSize size: CGFloat) -> UIFont {
        return UIFont(name: AppFontName.italic, size: size)!
    }

    @objc convenience init(myCoder aDecoder: NSCoder) {
        guard
            let fontDescriptor = aDecoder.decodeObject(forKey: "UIFontDescriptor") as? UIFontDescriptor,
            let fontAttribute = fontDescriptor.fontAttributes[.nsctFontUIUsage] as? String else {
                self.init(myCoder: aDecoder)
                return
        }
        var fontName = ""
        switch fontAttribute {
        case "CTFontRegularUsage":
            fontName = AppFontName.regular
        case "CTFontEmphasizedUsage", "CTFontBoldUsage":
            fontName = AppFontName.bold
        case "CTFontObliqueUsage":
            fontName = AppFontName.italic
        default:
            fontName = AppFontName.regular
        }
        self.init(name: fontName, size: fontDescriptor.pointSize)!
    }

    class func overrideInitialize() {
        guard self == UIFont.self, !isOverrided else { return }

        // Avoid method swizzling run twice and revert to original initialize function
        isOverrided = true

        if let systemFontMethod = class_getClassMethod(self, #selector(systemFont(ofSize:))),
            let mySystemFontMethod = class_getClassMethod(self, #selector(mySystemFont(ofSize:))) {
            method_exchangeImplementations(systemFontMethod, mySystemFontMethod)
        }

        if let boldSystemFontMethod = class_getClassMethod(self, #selector(boldSystemFont(ofSize:))),
            let myBoldSystemFontMethod = class_getClassMethod(self, #selector(myBoldSystemFont(ofSize:))) {
            method_exchangeImplementations(boldSystemFontMethod, myBoldSystemFontMethod)
        }

        if let italicSystemFontMethod = class_getClassMethod(self, #selector(italicSystemFont(ofSize:))),
            let myItalicSystemFontMethod = class_getClassMethod(self, #selector(myItalicSystemFont(ofSize:))) {
            method_exchangeImplementations(italicSystemFontMethod, myItalicSystemFontMethod)
        }

        if let initCoderMethod = class_getInstanceMethod(self, #selector(UIFontDescriptor.init(coder:))), // Trick to get over the lack of UIFont.init(coder:))
            let myInitCoderMethod = class_getInstanceMethod(self, #selector(UIFont.init(myCoder:))) {
            method_exchangeImplementations(initCoderMethod, myInitCoderMethod)
        }
    }
}


class AppDelegate: UIResponder, UIApplicationDelegate {
    // Avoid warning of Swift
    // Method 'initialize()' defines Objective-C class method 'initialize', which is not guaranteed to be invoked by Swift and will be disallowed in future versions
    override init() {
        super.init()
        UIFont.overrideInitialize()
    }
    ...
}

I would suggest Travis for Open source project. It's just simple to configure and use.

Simple steps to setup:

1. Should have GITHUB account and register in Travis CI website using your GITHUB account.
2. Add .travis.yml file in root of your project. Add Travis as service in your repository settings page.

Now every time you commit into your repository Travis will build your project. You can follow simple steps to get started with Travis CI.

Please check this example here: Accessing Structure Members

There is explained that the right way to do it is like this:

strcpy(s1.name , "Egzona");
printf( "Name : %s\n", s1.name);

In my opinion the best tool for such testing is curl. Its --upload-file option uploads a file by PUT, which is exactly what you want (and it can do much more, like modifying HTTP headers, in case you need it):

curl http://myservice --upload-file file.txt

It looks like you are trying to do this?

Iterate and mutate an array using Array.prototype.splice

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'b', 'c', 'b', 'a'];

review.forEach(function(item, index, object) {
  if (item === 'a') {
    object.splice(index, 1);
  }
});

log(review);

<pre id="out"></pre>

Which works fine for simple case where you do not have 2 of the same values as adjacent array items, other wise you have this problem.

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];

review.forEach(function(item, index, object) {
  if (item === 'a') {
    object.splice(index, 1);
  }
});

log(review);

<pre id="out"></pre>

So what can we do about this problem when iterating and mutating an array? Well the usual solution is to work in reverse. Using ES3 while but you could use for sugar if preferred

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a' ,'a', 'b', 'c', 'b', 'a', 'a'],
  index = review.length - 1;

while (index >= 0) {
  if (review[index] === 'a') {
    review.splice(index, 1);
  }

  index -= 1;
}

log(review);

<pre id="out"></pre>

Ok, but you wanted to use ES5 iteration methods. Well and option would be to use Array.prototype.filter but this does not mutate the original array but creates a new one, so while you can get the correct answer it is not what you appear to have specified.

We could also use ES5 Array.prototype.reduceRight, not for its reducing property by rather its iteration property, i.e. iterate in reverse.

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];

review.reduceRight(function(acc, item, index, object) {
  if (item === 'a') {
    object.splice(index, 1);
  }
}, []);

log(review);

<pre id="out"></pre>

Or we could use ES5 Array.protoype.indexOf like so.

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'],
  index = review.indexOf('a');

while (index !== -1) {
  review.splice(index, 1);
  index = review.indexOf('a');
}

log(review);

<pre id="out"></pre>

But you specifically want to use ES5 Array.prototype.forEach, so what can we do? Well we need to use Array.prototype.slice to make a shallow copy of the array and Array.prototype.reverse so we can work in reverse to mutate the original array.

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];

review.slice().reverse().forEach(function(item, index, object) {
  if (item === 'a') {
    review.splice(object.length - 1 - index, 1);
  }
});

log(review);

<pre id="out"></pre>

Finally ES6 offers us some further alternatives, where we do not need to make shallow copies and reverse them. Notably we can use Generators and Iterators. However support is fairly low at present.

var pre = document.getElementById('out');

function log(result) {
  pre.appendChild(document.createTextNode(result + '\n'));
}

function* reverseKeys(arr) {
  var key = arr.length - 1;

  while (key >= 0) {
    yield key;
    key -= 1;
  }
}

var review = ['a', 'a', 'b', 'c', 'b', 'a', 'a'];

for (var index of reverseKeys(review)) {
  if (review[index] === 'a') {
    review.splice(index, 1);
  }
}

log(review);

<pre id="out"></pre>

Something to note in all of the above is that, if you were stripping NaN from the array then comparing with equals is not going to work because in Javascript NaN === NaN is false. But we are going to ignore that in the solutions as it it yet another unspecified edge case.

So there we have it, a more complete answer with solutions that still have edge cases. The very first code example is still correct but as stated, it is not without issues.

Okay, so this post is from six months ago, but I thought I would add some info here for people who are confused about the whole API key/MD5 fingerprint business. It took me a while to figure out, so I assume others have had trouble with it too (unless I'm just that dull).

These directions are for Windows XP, but I imagine it is similar for other versions of Windows. It appears Mac and Linux users have an easier time with this so I won't address them.

So in order to use mapviews in your Android apps, Google wants to check in with them so you can sign off on an Android Maps APIs Terms Of Service agreement. I think they don't want you to make any turn-by-turn GPS apps to compete with theirs or something. I didn't really read it. Oops.

So go to http://code.google.com/android/maps-api-signup.html and check it out. They want you to check the "I have read and agree with the terms and conditions" box and enter your certificate's MD5 fingerprint. Wtf is that, you might say. I don't know, but just do what I say and your Android app doesn't get hurt.

Go to Start>Run and type cmd to open up a command prompt. You need to navigate to the directory with the keytool.exe file, which might be in a slightly different place depending on which version JDK you have installed. Mine is in C:\Program Files\Java\jdk1.6.0_21\bin but try browsing to the Java folder and see what version you have and change the path accordingly.

After navigating to C:\Program Files\Java\<"your JDK version here">\bin in the command prompt, type

keytool -list -keystore "C:/Documents and Settings/<"your user name here">/.android/debug.keystore"

with the quotes. Of course <"your user name here"> would be your own Windows username.

(If you are having trouble finding this path and you are using Eclipse, you can check Window>preferences>Android>Build and check out the "Default Debug keystore")

Press enter and it will prompt you for a password. Just press enter. And voila, at the bottom is your MD5 fingerprint. Type your fingerprint into the text box at the Android Maps API Signup page and hit Generate API Key.

And there's your key in all its glory, with a handy sample xml layout with your key entered for you to copy and paste.

I don't see why you shouldn't be able to send html content via a post.

if you encounter any issues, you could perhaps use some kind of encoding / decoding - but I don't see that you will.

By default VS is not made to run PHP, but you can do it with extensions:

You can install an add-on with the extension manager, PHP Tools for Visual Studio.

If you want to install it inside VS, go to Tools > Extension Manager > Online Gallery > Search for PHP where you will find PHP Tools (the link above) for Visual Studio. Also you have VS.Php for Visual Studio. Both are not free.

You have also a cool PHP compiler called Phalanger:

If I'm not mistaken, the code you wrote above is JavaScript (jQuery) and not PHP.

        Dim objFolder As Shell32.Folder

        objFolder = shell.NameSpace("C:\tmp")

        For i = 0 To 34
            arrHeaders(i) = objFolder.GetDetailsOf(objFolder.Items, i)
        Next
        For Each strFileName In objfolder.Items
            For i = 0 To 34
                Console.WriteLine(i & vbTab & arrHeaders(i) & ": " & objfolder.GetDetailsOf(strFileName, i))
            Next
