I would tackle the problem like this:

    BufferedWriter output;
    output = new BufferedWriter(new FileWriter("file.txt", true));
    String sizeX = jTextField1.getText();
    String sizeY = jTextField2.getText();
    output.append(sizeX);
    output.append(sizeY);
    output.newLine();
    output.close();

The true in the FileWriter constructor allows to append.
The method newLine() is provided by BufferedWriter
Could be ok as solution?

My biggest "D'oh" moment! I've been compiling it on Eclipse rather than cmd which was where I was executing it. So my newly compiled classes went to the bin folder and the compiled class file via command prompt remained the same in my src folder. I recompiled with my new code and it works like a charm.

File fold = new File("../playlist/" + existingPlaylist.getText() + ".txt");
fold.delete();

File fnew = new File("../playlist/" + existingPlaylist.getText() + ".txt");

String source = textArea.getText();
System.out.println(source);

try {
    FileWriter f2 = new FileWriter(fnew, false);
    f2.write(source);
    f2.close();

} catch (IOException e) {
    e.printStackTrace();
}   

Since Java 1.7 you can use Files.createFile:

Path pathToFile = Paths.get("/home/joe/foo/bar/myFile.txt");
Files.createDirectories(pathToFile.getParent());
Files.createFile(pathToFile);

The FacetGrid plot does produce pretty small labels. While @paul-h has described the use of sns.set as a way to the change the font scaling, it may not be the optimal solution since it will change the font_scale setting for all plots.

You could use the seaborn.plotting_context to change the settings for just the current plot:

with sns.plotting_context(font_scale=1.5):
    sns.factorplot(x, y ...)

To the best of my knowledge, JavaScript's objects are garbage collected periodically when there are no references remaining to the object. It is something that happens automatically, but if you want to see more about how it works, at the C++ level, it makes sense to take a look at the WebKit or V8 source code

Typically you don't need to think about it, however, in older browsers, like IE 5.5 and early versions of IE 6, and perhaps current versions, closures would create circular references that when unchecked would end up eating up memory. In the particular case that I mean about closures, it was when you added a JavaScript reference to a dom object, and an object to a DOM object that referred back to the JavaScript object. Basically it could never be collected, and would eventually cause the OS to become unstable in test apps that looped to create crashes. In practice these leaks are usually small, but to keep your code clean you should delete the JavaScript reference to the DOM object.

Usually it is a good idea to use the delete keyword to immediately de-reference big objects like JSON data that you have received back and done whatever you need to do with it, especially in mobile web development. This causes the next sweep of the GC to remove that object and free its memory.

This can be done by using SUMPRODUCT as well. Update the ranges as you see fit

=SUMPRODUCT(($A$2:$A$7=A2)*($B$2:$B$7=B2)*$C$2:$C$7)

A2:A7 = First name range

B2:B7 = Last Name Range

C2:C7 = Numbers Range

This will find all the names with the same first and last name and sum the numbers in your numbers column

Without root, you can use debug proxies like Charlesproxy&Co.

@echo off and title can come before this code:

net session>nul 2>&1
if %errorlevel%==0 goto main
echo CreateObject("Shell.Application").ShellExecute "%~f0", "", "", "runas">"%temp%/elevate.vbs"
"%temp%/elevate.vbs"
del "%temp%/elevate.vbs"
exit

:main
    <code goes here>
exit

A lot of the other answers are overkill if you don't need to worry about the following:

• Parameters
• Working Directory (cd %~dp0 will change to the directory containing the batch file)

It's a frequently asked question why main() is static in Java.

Answer: We know that in Java, execution starts from main() by JVM. When JVM executes main() at that time, the class which contains main() is not instantiated so we can't call a nonstatic method without the reference of it's object. So to call it we made it static, due to which the class loader loads all the static methods in JVM context memory space from where JVM can directly call them.

You can filter the array and then just pick the first element, as shown in Find Object with Property in Array.

Or you define a custom extension

extension Array {

    // Returns the first element satisfying the predicate, or `nil`
    // if there is no matching element.
    func findFirstMatching<L : BooleanType>(predicate: T -> L) -> T? {
        for item in self {
            if predicate(item) {
                return item // found
            }
        }
        return nil // not found
    }
}

Usage example:

struct T {
    var name : String
}

let array = [T(name: "bar"), T(name: "baz"), T(name: "foo")]

if let item = array.findFirstMatching( { $0.name == "foo" } ) {
    // item is the first matching array element
} else {
    // not found
}

In Swift 3 you can use the existing first(where:) method (as mentioned in a comment):

if let item = array.first(where: { $0.name == "foo" }) {
    // item is the first matching array element
} else {
    // not found
}

Unfortunately, IE and VLC don't really work right now... I found this on the vlc forums:

VLC included activex support up until version 0.8.6, I believe. At that time, you could
access a cab on the videolan and therefore 'automatic' installation into IE and Firefox
family browsers was fine. Thereafter support for activex seemed to stop; no cab, no
activex component.

VLC 1.0.* once again contains activex support, and that's brilliant. A good decision in
my opinion. What's lacking is a cab installer for the latest version.

This basically means that even if you found a way to make it work, anyone trying to view the video on your site in IE would have to download and install the entire VLC player program to have it work in IE, and users probably don't want to do that. I can't get your code to work in firefox or IE8 on my boyfriends computer, although I might not have been putting the video address in properly... I get some message about no video output...

I'll take a guess and say it probably works for you locally because you have VLC installed, but your server doesn't. Unfortunately you'll probably have to use Windows media player or something similar (Microsoft is great at forcing people to use their stuff!)

And if you're wondering, it appears that the reason there is no cab file is because of the cost of having an active-x control signed.

It's rather simple to have your page use VLC for firefox and chrome users, and Windows Media Player for IE users, if that would work for you.

The template it is referring to is the Html helper DisplayFor.

DisplayFor expects to be given an expression that conforms to the rules as specified in the error message.

You are trying to pass in a method chain to be executed and it doesn't like it.

This is a perfect example of where the MVVM (Model-View-ViewModel) pattern comes in handy.

You could wrap up your Trainer model class in another class called TrainerViewModel that could work something like this:

class TrainerViewModel
{
    private Trainer _trainer;

    public string ShortDescription
    {
        get
        {
            return _trainer.Description.ToString().Substring(0, 100);
        }
    }

    public TrainerViewModel(Trainer trainer)
    {
        _trainer = trainer;
    }
}

You would modify your view model class to contain all the properties needed to display that data in the view, hence the name ViewModel.

Then you would modify your controller to return a TrainerViewModel object rather than a Trainer object and change your model type declaration in your view file to TrainerViewModel too.

I had a directory of files that I wanted to check. I created an Excel macro to determine ANSI vs. UTF-8. This worked for me.

        Sub GetTextFileEncoding()
        Dim sFile As String

        iRow = 1
        sPath = "C:textfiles\"
        sFile = Dir(sPath & "*.txt")

        Do While Len(sFile) > 0
            'Get FileType
            'Debug.Print sFile & " - " & FileEncodeType(sPath & sFile)

            Cells(iRow, 1).Value = sFile
            Cells(iRow, 2).Value = FileEncodeType(sPath & sFile)

            sFile = Dir

            'Increment Row

                Next
            End If
        Close #1

        If bEF And bBB And bBF Then
            FileEncodeType = "UTF-8"
        Else

Save the following script as something like findPK.sql.

set verify off
accept TABLE_NAME char prompt 'Table name>'

SELECT cols.column_name
FROM all_constraints cons NATURAL JOIN all_cons_columns cols
WHERE cons.constraint_type = 'P' AND table_name = UPPER('&TABLE_NAME');

It can then be called using

@findPK

One alternative method is convert your List to array, iterate them and remove them directly from the List based on your logic.

List<String> myList = new ArrayList<String>(); // You can use either list or set

myList.add("abc");
myList.add("abcd");
myList.add("abcde");
myList.add("abcdef");
myList.add("abcdefg");

Object[] obj = myList.toArray();

for(Object o:obj)  {
    if(condition)
        myList.remove(o.toString());
}

There are two ways of looking at github content, the "raw" way and the "Web page" way.

raw.githubusercontent.com returns the raw content of files stored in github, so they can be downloaded simply to your computer. For example, if the page represents a ruby install script, then you will get a ruby install script that your ruby installation will understand.

If you instead download the file using the github.com link, you will actually be downloading a web page with buttons and comments and which displays your wanted script in the middle -- it's what you want to give to your web browser to get a nice page to look at, but for the computer, it is not a script that can be executed or code that can be compiled, but a web page to be displayed. That web page has a button called Raw that sends you to the corresponding content on raw.githubusercontent.com.

To see the content of raw.githubusercontent.com/${repo}/${branch}/${path} in the usual github interface:

1. you replace raw.githubusercontent.com with plain github.com
2. AND you insert "blob" between the repo name and the branch name.

In this case, the branch name is "master" (which is a very common branch name), so you replace /master/ with /blob/master/, and so

https://raw.githubusercontent.com/Homebrew/install/master/install

becomes

https://github.com/Homebrew/install/blob/master/install

This is the reverse of finding a file on Github and clicking the Raw link.

Place your widget.js after core.js, but before any other jquery that calls the widget.js file. (Example: draggable.js) Precedence (order) matters in what javascript/jquery can 'see'. Always position helper code before the code that uses the helper code.

Here is the easiest solution which works for me without writing additional codes.

// To underline text in UILable
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"Type your text here"];
[text addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(0, text.length)];
lblText.attributedText = text;

In vi...

:set list to see line-endings.

:set nolist to go back to normal.

While I don't think you can see \n or \r\n in vi, you can see which type of file it is (UNIX, DOS, etc.) to infer which line endings it has...

:set ff

Alternatively, from bash you can use od -t c <filename> or just od -c <filename> to display the returns.

Check your %temp% folder after download. In my case, download went both in temp folder and one I specified. After download was completed, files from temp folder were not deleted.
Also, make sure to have enough space on system partition (or wherever your %temp% is) in the first place. For community edition download is over 16GB for everything.

Try using jQuery to avoid cross browser compatibility problems...

$("textarea").keyup(function(){
    if($(this).text().length > 500){
        var text = $(this).text();
        $(this).text(text.substr(0, 500));   
    }
});

You can trust particular certificate at runtime.
Just download it from server, put in assets and load like this using ssl-utils-android:

OkHttpClient client = new OkHttpClient();
SSLContext sslContext = SslUtils.getSslContextForCertificateFile(context, "BPClass2RootCA-sha2.cer");
client.setSslSocketFactory(sslContext.getSocketFactory());

In the example above I used OkHttpClient but SSLContext can be used with any client in Java.

It's pandas label-based selection, as explained here: https://pandas.pydata.org/pandas-docs/stable/indexing.html#selection-by-label

The boolean array is basically a selection method using a mask.

I can't believe there's no cut'n'paste solution in this thread after 5 years!
SO: To get the same time-of-day regardless of summertime interference:

Date.prototype.addDays = function(days)
    {
    var dat = new Date( this.valueOf() )

    var hour1 = dat.getHours()
    dat.setTime( dat.getTime() + days * 86400000) // 24*60*60*1000 = 24 hours
    var hour2 = dat.getHours()

    if (hour1 != hour2) // summertime occured +/- a WHOLE number of hours thank god!
        dat.setTime( dat.getTime() + (hour1 - hour2) * 3600000) // 60*60*1000 = 1 hour

    return dat
or
    this.setTime( dat.getTime() ) // to modify the object directly
    }

There. Done!

Follow the next steps:

1. Open the app.config and comment on the connection string (save file)
2. Open the edmx (go to properties, the connection string should be blank), close the edmx file again
3. Open the app.config and uncomment the connection string (save file)
4. Open the edmx, go to properties, you should see the connection string uptated!!

While I do love using CHECKSUM, I feel that a better way to go is using NEWID(), just because you don't have to go through a complicated math to generate simple numbers .

ROUND( 1000 *RAND(convert(varbinary, newid())), 0)

You can replace the 1000 with whichever number you want to set as the limit, and you can always use a plus sign to create a range, let's say you want a random number between 100 and 200, you can do something like :

100 + ROUND( 100 *RAND(convert(varbinary, newid())), 0)

Putting it together in your query :

UPDATE CattleProds 
SET SheepTherapy= ROUND( 1000 *RAND(convert(varbinary, newid())), 0)
WHERE SheepTherapy IS NULL

Following @Joshua's suggestion, here's one way you might count the number of observations in your df dataframe where Year = 2007 and Month = Nov (assuming they are columns):

nrow(df[,df$YEAR == 2007 & df$Month == "Nov"])

and with aggregate, following @GregSnow:

aggregate(x ~ Year + Month, data = df, FUN = length)

Make a list of all letters in the US English Alphabet, skipping a & b. "CDEFGHIJKLMNOPQRSTUVWXYZ". Open each of those drives with CreateFile e.g. CreateFile("\\.\C:"). If it does not return INVALID_HANDLE_VALUE then you got a 'good' drive. Next take that handle and run it through DeviceIoControl to get the Disk #. See my related answer for more details.

When you have the expression:

a % b = c

It really means there exists an integer n that makes c as small as possible, but non-negative.

a - n*b = c

By hand, you can just subtract 2 (or add 2 if your number is negative) over and over until the end result is the smallest positive number possible:

  3.14 % 2
= 3.14 - 1 * 2
= 1.14

Also, 3.14 % 2 * pi is interpreted as (3.14 % 2) * pi. I'm not sure if you meant to write 3.14 % (2 * pi) (in either case, the algorithm is the same. Just subtract/add until the number is as small as possible).

After going through other answers I came up with this, just apply class nested-counter-list to root ol tag:

sass code:

ol.nested-counter-list {
  counter-reset: item;

  li {
    display: block;

    &::before {
      content: counters(item, ".") ". ";
      counter-increment: item;
      font-weight: bold;
    }
  }

  ol {
    counter-reset: item;

    & > li {
      display: block;

      &::before {
        content: counters(item, ".") " ";
        counter-increment: item;
        font-weight: bold;
      }
    }
  }
}

css code:

ol.nested-counter-list {
  counter-reset: item;
}
ol.nested-counter-list li {
  display: block;
}
ol.nested-counter-list li::before {
  content: counters(item, ".") ". ";
  counter-increment: item;
  font-weight: bold;
}
ol.nested-counter-list ol {
  counter-reset: item;
}
ol.nested-counter-list ol > li {
  display: block;
}
ol.nested-counter-list ol > li::before {
  content: counters(item, ".") " ";
  counter-increment: item;
  font-weight: bold;
}

ol.nested-counter-list {
  counter-reset: item;
}

ol.nested-counter-list li {
  display: block;
}

ol.nested-counter-list li::before {
  content: counters(item, ".") ". ";
  counter-increment: item;
  font-weight: bold;
}

ol.nested-counter-list ol {
  counter-reset: item;
}

ol.nested-counter-list ol>li {
  display: block;
}

ol.nested-counter-list ol>li::before {
  content: counters(item, ".") " ";
  counter-increment: item;
  font-weight: bold;
}

<ol class="nested-counter-list">
  <li>one</li>
  <li>two
    <ol>
      <li>two.one</li>
      <li>two.two</li>
      <li>two.three</li>
    </ol>
  </li>
  <li>three
    <ol>
      <li>three.one</li>
      <li>three.two
        <ol>
          <li>three.two.one</li>
          <li>three.two.two</li>
        </ol>
      </li>
    </ol>
  </li>
  <li>four</li>
</ol>

And if you need trailing . at the end of the nested list's counters use this:

ol.nested-counter-list {
  counter-reset: item;
}

ol.nested-counter-list li {
  display: block;
}

ol.nested-counter-list li::before {
  content: counters(item, ".") ". ";
  counter-increment: item;
  font-weight: bold;
}

ol.nested-counter-list ol {
  counter-reset: item;
}

<ol class="nested-counter-list">
  <li>one</li>
  <li>two
    <ol>
      <li>two.one</li>
      <li>two.two</li>
      <li>two.three</li>
    </ol>
  </li>
  <li>three
    <ol>
      <li>three.one</li>
      <li>three.two
        <ol>
          <li>three.two.one</li>
          <li>three.two.two</li>
        </ol>
      </li>
    </ol>
  </li>
  <li>four</li>
</ol>

Option1:

List<String> list = Arrays.asList("hello");

Option2:

List<String> list = new ArrayList<String>(Arrays.asList("hello"));

In my opinion, Option1 is better because

1. we can reduce the number of ArrayList objects being created from 2 to 1. asList method creates and returns an ArrayList Object.
2. its performance is much better (but it returns a fixed-size list).

Please refer to the documentation here

$sql = $dbh->prepare("SELECT * from member WHERE member_email = '$username' AND member_password = '$password'");

$sql->execute();

$fetch = $sql->fetch(PDO::FETCH_ASSOC);

// if not empty result
if (is_array($fetch))  {
    $_SESSION["userMember"] = $fetch["username"];
    $_SESSION["password"] = $fetch["password"];
    echo 'yes this member is registered'; 
}else {
    echo 'empty result!';
}

You need to include the appropriate header

#include <stdio.h>

If you're not sure which header a standard function is defined in, the function's man page will state this.

An easy way that works:

private void dataGrid_SelectedCellsChanged(object sender, SelectedCellsChangedEventArgs e)
{
    foreach (var item in e.AddedCells)
    {
        var col = item.Column as DataGridColumn;
        var fc = col.GetCellContent(item.Item);

        if (fc is CheckBox)
        {
            Debug.WriteLine("Values" + (fc as CheckBox).IsChecked);
        }
        else if(fc is TextBlock)
        {
            Debug.WriteLine("Values" + (fc as TextBlock).Text);
        }
        //// Like this for all available types of cells
    }
}

Another way is to use an array as a type, e.g.:

Video[] videoArray = gson.fromJson(json, Video[].class);

This way you avoid all the hassle with the Type object, and if you really need a list you can always convert the array to a list, e.g.:

List<Video> videoList = Arrays.asList(videoArray);

IMHO this is much more readable.

In Kotlin this looks like this:

Gson().fromJson(jsonString, Array<Video>::class.java)

To convert this array into List, just use .toList() method

I could not comment and thus am adding this as an answer.
We had some pain trying to map existing types to a javascript library.

To map a .d.ts file to its javascript file you need to give the .d.ts file the same name as the javascript file, keep them in the same folder, and point the code that needs it to the .d.ts file.

eg: test.js and test.d.ts are in the testdir/ folder, then you import it like this in a react component:

import * as Test from "./testdir/test";

The .d.ts file was exported as a namespace like this:

export as namespace Test;

export interface TestInterface1{}
export class TestClass1{}

Try adding:

<dependency>
    <groupId>com.owlike</groupId>
    <artifactId>genson</artifactId>

Also this problem may occur if you're using HTTP GET with message body so in this case adding jersey-json lib, @XmlRootElement or modifying web.xml won't help. You should use URL QueryParam or HTTP POST.

You could read Google answer for it here: http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml#Preincrement_and_Predecrement

So, main point is, what no difference for simple object, but for iterators and other template objects you should use preincrement.

EDITED:

There are no difference because you use simple type, so no side effects, and post- or preincrements executed after loop body, so no impact on value in loop body.

You could check it with such a loop:

for (int i = 0; i < 5; cout << "we still not incremented here: " << i << endl, i++)
{
    cout << "inside loop body: " << i << endl;
}

If you want to extract structured data from Wikipedia, you may consider using DbPedia http://dbpedia.org/

It provides means to query data using given criteria using SPARQL and returns data from parsed Wikipedia infobox templates

Here is a quick example how it could be done in .NET http://www.kozlenko.info/blog/2010/07/20/executing-sparql-query-on-wikipedia-in-net/

There are some SPARQL libraries available for multiple platforms to make queries easier

if your using react-slick you can try this on custom next and prev divs

https://react-slick.neostack.com/docs/example/previous-next-methods

It should not effect the load time much since you are overriding parts of the base stylesheet.

Here are some best practices I personally follow:

1. Always load custom CSS after the base CSS file (not responsive).
2. Avoid using !important if possible. That can override some important styles from the base CSS files.
3. Always load bootstrap-responsive.css after custom.css if you don't want to lose media queries. - MUST FOLLOW
4. Prefer modifying required properties (not all).

Try this first, you may be passing a Null Model:

@if (Model != null && !String.IsNullOrEmpty(Model.ImageName))
{
    <label for="Image">Change picture</label>
}
else
{ 
    <label for="Image">Add picture</label>
}

Otherise, you can make it even neater with some ternary fun! - but that will still error if your model is Null.

<label for="Image">@(String.IsNullOrEmpty(Model.ImageName) ? "Add" : "Change") picture</label>

From the documentation:

It is necessary to keep in mind that the browsers do not know how to correctly show this error.

I suspect this is what's happening, if you inspect the HTTP to-and-fro using tools such as Firebug or Live HTTP Headers (both Firefox extensions) you'll be able to see what's really going on.

SHORT ANSWER

How to do in your case:

int argument = 5; // example with int but could be another type
Mockito.when(mockMyAgent.otherMethod(Mockito.anyInt()).thenReturn(requiredReturnArg(argument));

LONG ANSWER

Actually what you want to do is possible, at least in Java 8. Maybe you didn't get this answer by other people because I am using Java 8 that allows that and this question is before release of Java 8 (that allows to pass functions, not only values to other functions).

Let's simulate a call to a DataBase query. This query returns all the rows of HotelTable that have FreeRoms = X and StarNumber = Y. What I expect during testing, is that this query will give back a List of different hotel: every returned hotel has the same value X and Y, while the other values and I will decide them according to my needs. The following example is simple but of course you can make it more complex.

So I create a function that will give back different results but all of them have FreeRoms = X and StarNumber = Y.

static List<Hotel> simulateQueryOnHotels(int availableRoomNumber, int starNumber) {
    ArrayList<Hotel> HotelArrayList = new ArrayList<>();
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Rome, 1, 1));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Krakow, 7, 15));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Madrid, 1, 1));
    HotelArrayList.add(new Hotel(availableRoomNumber, starNumber, Athens, 4, 1));

    return HotelArrayList;
}

Maybe Spy is better (please try), but I did this on a mocked class. Here how I do (notice the anyInt() values):

//somewhere at the beginning of your file with tests...
@Mock
private DatabaseManager mockedDatabaseManager;

//in the same file, somewhere in a test...
int availableRoomNumber = 3;
int starNumber = 4;
// in this way, the mocked queryOnHotels will return a different result according to the passed parameters
when(mockedDatabaseManager.queryOnHotels(anyInt(), anyInt())).thenReturn(simulateQueryOnHotels(availableRoomNumber, starNumber));

Try this easy 2019 jquery solution, although its been around a while;

1. add this plugin to head:

   src="https://code.jquery.com/ui/1.12.0/jquery-ui.min.js"

2. add this to js:

   $("*").on("touchend", function(e) { $(this).focus(); }); //applies to all elements

3. some suggested variations to this are:

   $(":input, :checkbox,").on("touchend", function(e) {(this).focus);}); //specify elements

   $("*").on("click, touchend", function(e) { $(this).focus(); }); //include click event

   css: body { cursor: pointer; } //touch anywhere to end a focus

Notes

• place plugin before bootstrap.js to avoif affecting tooltips
• only tested on iphone XR ios 12.1.12, and ipad 3 ios 9.3.5, using Safari or Chrome.

For my system, I had numerous IPv4 Addresses, only one of which was correct. A simple way to sort out and check it is as follows:

for /f "tokens=1,2* delims=:" %%A in ('ipconfig ^| find "IPv4 Address"') do (
    set "tempip=%%~B"
    set "tempip=!tempip: =!"
    ping !tempip! -n 1 -w 50
    if !errorlevel!==0 (
        set localip=!tempip!
        goto foundlocal
    )
)

If the datepicker is in a row of a grid, try something like

editoptions : {
    dataInit : function (e) {
        $(e).datepicker({
            onSelect : function (ev) {
                // here your code
            }
        });
    }
}

The array decays to a pointer when passed.

Section 6.4 of the C FAQ covers this very well and provides the K&R references etc.

That aside, imagine it were possible for the function to know the size of the memory allocated in a pointer. You could call the function two or more times, each time with different input arrays that were potentially different lengths; the length would therefore have to be passed in as a secret hidden variable somehow. And then consider if you passed in an offset into another array, or an array allocated on the heap (malloc and all being library functions - something the compiler links to, rather than sees and reasons about the body of).

Its getting difficult to imagine how this might work without some behind-the-scenes slice objects and such right?

Symbian did have a AllocSize() function that returned the size of an allocation with malloc(); this only worked for the literal pointer returned by the malloc, and you'd get gobbledygook or a crash if you asked it to know the size of an invalid pointer or a pointer offset from one.

You don't want to believe its not possible, but it genuinely isn't. The only way to know the length of something passed into a function is to track the length yourself and pass it in yourself as a separate explicit parameter.

On SQL Server, this will list all the indexes for a specified table:

select * from sys.indexes
where object_id = (select object_id from sys.objects where name = 'MYTABLE')

This query will list all tables without an index:

SELECT name
FROM sys.tables 
WHERE OBJECTPROPERTY(object_id,'IsIndexed') = 0

And this is an interesting MSDN FAQ on a related subject:
Querying the SQL Server System Catalog FAQ

line=`sed -n 2p myfile`
echo $line

Try: 

SELECT EXTRACT(EPOCH FROM (timestamp_B - timestamp_A))
FROM TableA

Details here: EXTRACT.

You could also just change the @RequestParam default required status to false so that HTTP response status code 400 is not generated. This will allow you to place the Annotations in any order you feel like.

For those trying to make the connection between SNR and a normal random variable generated by numpy:

[1] , where it's important to keep in mind that P is average power.

Or in dB:
[2]

In this case, we already have a signal and we want to generate noise to give us a desired SNR.

While noise can come in different flavors depending on what you are modeling, a good start (especially for this radio telescope example) is Additive White Gaussian Noise (AWGN). As stated in the previous answers, to model AWGN you need to add a zero-mean gaussian random variable to your original signal. The variance of that random variable will affect the average noise power.

For a Gaussian random variable X, the average power , also known as the second moment, is
[3]

So for white noise, and the average power is then equal to the variance .

When modeling this in python, you can either
1. Calculate variance based on a desired SNR and a set of existing measurements, which would work if you expect your measurements to have fairly consistent amplitude values.
2. Alternatively, you could set noise power to a known level to match something like receiver noise. Receiver noise could be measured by pointing the telescope into free space and calculating average power.

Either way, it's important to make sure that you add noise to your signal and take averages in the linear space and not in dB units.

Here's some code to generate a signal and plot voltage, power in Watts, and power in dB:

# Signal Generation
# matplotlib inline

import numpy as np
import matplotlib.pyplot as plt

t = np.linspace(1, 100, 1000)
x_volts = 10*np.sin(t/(2*np.pi))
plt.subplot(3,1,1)
plt.plot(t, x_volts)
plt.title('Signal')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()

x_watts = x_volts ** 2
plt.subplot(3,1,2)
plt.plot(t, x_watts)
plt.title('Signal Power')
plt.ylabel('Power (W)')
plt.xlabel('Time (s)')
plt.show()

x_db = 10 * np.log10(x_watts)
plt.subplot(3,1,3)
plt.plot(t, x_db)
plt.title('Signal Power in dB')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

Here's an example for adding AWGN based on a desired SNR:

# Adding noise using target SNR

# Set a target SNR
target_snr_db = 20
# Calculate signal power and convert to dB 
sig_avg_watts = np.mean(x_watts)
sig_avg_db = 10 * np.log10(sig_avg_watts)
# Calculate noise according to [2] then convert to watts
noise_avg_db = sig_avg_db - target_snr_db
noise_avg_watts = 10 ** (noise_avg_db / 10)
# Generate an sample of white noise
mean_noise = 0
noise_volts = np.random.normal(mean_noise, np.sqrt(noise_avg_watts), len(x_watts))
# Noise up the original signal
y_volts = x_volts + noise_volts

# Plot signal with noise
plt.subplot(2,1,1)
plt.plot(t, y_volts)
plt.title('Signal with noise')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()
# Plot in dB
y_watts = y_volts ** 2
y_db = 10 * np.log10(y_watts)
plt.subplot(2,1,2)
plt.plot(t, 10* np.log10(y_volts**2))
plt.title('Signal with noise (dB)')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

And here's an example for adding AWGN based on a known noise power:

# Adding noise using a target noise power

# Set a target channel noise power to something very noisy
target_noise_db = 10

# Convert to linear Watt units
target_noise_watts = 10 ** (target_noise_db / 10)

# Generate noise samples
mean_noise = 0
noise_volts = np.random.normal(mean_noise, np.sqrt(target_noise_watts), len(x_watts))

# Noise up the original signal (again) and plot
y_volts = x_volts + noise_volts

# Plot signal with noise
plt.subplot(2,1,1)
plt.plot(t, y_volts)
plt.title('Signal with noise')
plt.ylabel('Voltage (V)')
plt.xlabel('Time (s)')
plt.show()
# Plot in dB
y_watts = y_volts ** 2
y_db = 10 * np.log10(y_watts)
plt.subplot(2,1,2)
plt.plot(t, 10* np.log10(y_volts**2))
plt.title('Signal with noise')
plt.ylabel('Power (dB)')
plt.xlabel('Time (s)')
plt.show()

working example in jsFiddle

This can be achieved using div. It can be done with table too. But i always prefer div.

<body id="doc-body" style="width: 100%; height: 100%; overflow: hidden; position: fixed" onload="InitApp()"> 
    <div>
        <!--If you don't need header background color you don't need this div.-->
        <div id="div-header-hack" style="height: 20px; position: absolute; background-color: gray"></div>

        <div id="div-header" style="position: absolute; top: 0px; overflow: hidden; height: 20px; background-color: gray">                
        </div>

        <div id="div-item" style="position: absolute; top: 20px; overflow: auto" onscroll="ScrollHeader()">                
        </div>
    </div>
</body>

Javascript:
please refer jsFiddle for this part. Else this answer becomes very lengthy.

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

What about:

1. Branch from the current HEAD.
2. Make sure you are on master, not your new branch.
3. git reset back to the last commit before you started making changes.
4. git pull to re-pull just the remote changes you threw away with the reset.

Or will that explode when you try to re-merge the branch?

I developed these 3 useful functions:

def loadModule(moduleName):
    module = None
    try:
        import sys
        del sys.modules[moduleName]
    except BaseException as err:
        pass
    try:
        import importlib
        module = importlib.import_module(moduleName)
    except BaseException as err:
        serr = str(err)
        print("Error to load the module '" + moduleName + "': " + serr)
    return module

def reloadModule(moduleName):
    module = loadModule(moduleName)
    moduleName, modulePath = str(module).replace("' from '", "||").replace("<module '", '').replace("'>", '').split("||")
    if (modulePath.endswith(".pyc")):
        import os
        os.remove(modulePath)
        module = loadModule(moduleName)
    return module

def getInstance(moduleName, param1, param2, param3):
    module = reloadModule(moduleName)
    instance = eval("module." + moduleName + "(param1, param2, param3)")
    return instance

And everytime I want to reload a new instance I just have to call getInstance() like this:

myInstance = getInstance("MyModule", myParam1, myParam2, myParam3)

Finally I can call all the functions inside the new Instance:

myInstance.aFunction()

The only specificity here is to customize the params list (param1, param2, param3) of your instance.

Try with:

$row = mysqli_fetch_assoc($result);
echo "my result <a href='data/" . htmlentities($row['classtype'], ENT_QUOTES, 'UTF-8') . ".php'>My account</a>";

To create a migration, you may use the migrate:make command on the Artisan CLI. Use a specific name to avoid clashing with existing models

for Laravel 3:

php artisan migrate:make add_paid_to_users

for Laravel 5+:

php artisan make:migration add_paid_to_users_table --table=users

You then need to use the Schema::table() method (as you're accessing an existing table, not creating a new one). And you can add a column like this:

public function up()
{
    Schema::table('users', function($table) {
        $table->integer('paid');
    });
}

and don't forget to add the rollback option:

public function down()
{
    Schema::table('users', function($table) {
        $table->dropColumn('paid');
    });
}

Then you can run your migrations:

php artisan migrate

This is all well covered in the documentation for both Laravel 3:

• Schema Builder
• Migrations

And for Laravel 4 / Laravel 5:

• Schema Builder
• Migrations

Edit:

use $table->integer('paid')->after('whichever_column'); to add this field after specific column.

Change the database.php file from

$db['default']['dbdriver'] = 'mysql';

to

$db['default']['dbdriver'] = 'mysqli';

Don't know why, but only thing that worked for me was using asset_path instead of image_path, even though my images are under the assets/images/ directory:

Example:

app/assets/images/mypic.png

In Ruby:

asset_path('mypic.png')

In .scss:

url(asset-path('mypic.png'))

UPDATE:

Figured it out- turns out these asset helpers come from the sass-rails gem (which I had installed in my project).

filename specifies the name of file into which all your bundled code is going to get accumulated after going through build step.

path specifies the output directory where the app.js(filename) is going to get saved in the disk. If there is no output directory, webpack is going to create that directory for you. for example:

module.exports = {
  output: {
    path: path.resolve("./examples/dist"),
    filename: "app.js"
  } 
}

This will create a directory myproject/examples/dist and under that directory it creates app.js, /myproject/examples/dist/app.js. After building, you can browse to myproject/examples/dist/app.js to see the bundled code

publicPath: "What should I put here?"

publicPath specifies the virtual directory in web server from where bundled file, app.js is going to get served up from. Keep in mind, the word server when using publicPath can be either webpack-dev-server or express server or other server that you can use with webpack.

for example

module.exports = {
  output: {
    path: path.resolve("./examples/dist"),
    filename: "app.js",
    publicPath: path.resolve("/public/assets/js")   
  } 
}

this configuration tells webpack to bundle all your js files into examples/dist/app.js and write into that file.

publicPath tells webpack-dev-server or express server to serve this bundled file ie examples/dist/app.js from specified virtual location in server ie /public/assets/js. So in your html file, you have to reference this file as

<script src="public/assets/js/app.js"></script>

So in summary, publicPath is like mapping between virtual directory in your server and output directory specified by output.path configuration, Whenever request for file public/assets/js/app.js comes, /examples/dist/app.js file will be served

That would be:

b.rstrip('\n')

If you want to strip space from each and every line, you might consider instead:

a.read().splitlines()

This will give you a list of lines, without the line end characters.

Not really an answer to your question but validating url's is really a serious p.i.t.a You're probably just better off validating the domainname and leave query part of the url be. That is my experience. You could also resort to pinging the url and seeing if it results in a valid response but that might be too much for such a simple task.

Regular expressions to detect url's are abundant, google it :)

TL;DR

function generateRandomInteger(min, max) {
  return Math.floor(min + Math.random()*(max + 1 - min))
}

To get the random number generateRandomInteger(-20, 20);

EXPLANATION BELOW

We need to get a random integer, say X between min and max.

Right?

i.e min <= X <= max

If we subtract min from the equation, this is equivalent to

0 <= (X - min) <= (max - min)

Now, lets multiply this with a random number r which is

0 <= (X - min) * r <= (max - min) * r

Now, lets add back min to the equation

min <= min + (X - min) * r <= min + (max - min) * r

Now, lets chose a function which results in r such that it satisfies our equation range as [min,max]. This is only possible if 0<= r <=1

OK. Now, the range of r i.e [0,1] is very similar to Math.random() function result. Isn't it?

The Math.random() function returns a floating-point, pseudo-random number in the range [0, 1); that is, from 0 (inclusive) up to but not including 1 (exclusive)

For example,

Case r = 0

min + 0 * (max-min) = min

Case r = 1

min + 1 * (max-min) = max

Random Case using Math.random 0 <= r < 1

min + r * (max-min) = X, where X has range of min <= X < max

The above result X is a random numeric. However due to Math.random() our left bound is inclusive, and the right bound is exclusive. To include our right bound we increase the right bound by 1 and floor the result.

function generateRandomInteger(min, max) {
  return Math.floor(min + Math.random()*(max + 1 - min))
}

To get the random number

generateRandomInteger(-20, 20);

You would have to tune it according to your environment.

Sometimes it's more useful to increase the size of the backlog (acceptCount) instead of the maximum number of threads.

Say, instead of

<Connector ... maxThreads="500" acceptCount="50"

you use

<Connector ... maxThreads="300" acceptCount="150"

you can get much better performance in some cases, cause there would be less threads disputing the resources and the backlog queue would be consumed faster.

In any case, though, you have to do some benchmarks to really know what is best.

A case when process get SIGABRT from itself: Hrvoje mentioned about a buried pure virtual being called from ctor generating an abort, i recreated an example for this. Here when d is to be constructed, it first calls its base class A ctor, and passes inside pointer to itself. the A ctor calls pure virtual method before table was filled with valid pointer, because d is not constructed yet.

#include<iostream>
using namespace std;
class A {
public:
 A(A *pa){pa->f();}
 virtual void f()=0;
};
class D : public A {
public:
 D():A(this){}
 virtual void f() {cout<<"D::f\n";}
};
int main(){
 D d;
 A *pa = &d;
 pa->f();
 return 0;
}

compile: g++ -o aa aa.cpp

ulimit -c unlimited

run: ./aa

pure virtual method called
terminate called without an active exception
Aborted (core dumped)

now lets quickly see the core file, and validate that SIGABRT was indeed called:

gdb aa core

A docker container exits when its main process finishes.

In this case it will exit when your start-all.sh script ends. I don't know enough about hadoop to tell you how to do it in this case, but you need to either leave something running in the foreground or use a process manager such as runit or supervisord to run the processes.

I think you must be mistaken about it working if you don't specify -d; it should have exactly the same effect. I suspect you launched it with a slightly different command or using -it which will change things.

A simple solution may be to add something like:

while true; do sleep 1000; done

to the end of the script. I don't like this however, as the script should really be monitoring the processes it kicked off.

(I should say I stole that code from https://github.com/sequenceiq/hadoop-docker/blob/master/bootstrap.sh)

Wrap an ArrayAdapter around your List<ScanResult>. Override getView() to populate your rows with the ScanResult data. Here is a free excerpt from one of my books that covers how to create custom ArrayAdapters like this.

Because JSON directly supports the \uxxxx syntax the first thing that comes into my mind is:

$unicodeChar = '\u1000';
echo json_decode('"'.$unicodeChar.'"');

Another option would be to use mb_convert_encoding()

echo mb_convert_encoding('က', 'UTF-8', 'HTML-ENTITIES');

or make use of the direct mapping between UTF-16BE (big endian) and the Unicode codepoint:

echo mb_convert_encoding("\x10\x00", 'UTF-8', 'UTF-16BE');

In my opinion cherry-picking should be reserved for rare situations where it is required, for example if you did some fix on directly on 'master' branch (trunk, main development branch) and then realized that it should be applied also to 'maint'. You should base workflow either on merge, or on rebase (or "git pull --rebase").

Please remember that cherry-picked or rebased commit is different from the point of view of Git (has different SHA-1 identifier) than the original, so it is different than the commit in remote repository. (Rebase can usually deal with this, as it checks patch id i.e. the changes, not a commit id).

Also in git you can merge many branches at once: so called octopus merge. Note that octopus merge has to succeed without conflicts. Nevertheless it might be useful.

Simply omitting the attribute or element works well in less formal data.

If you need more sophisticated information, the GML schemas add the attribute nilReason, eg: in GeoSciML:

• xsi:nil with a value of "true" is used to indicate that no value is available
• nilReason may be used to record additional information for missing values; this may be one of the standard GML reasons (missing, inapplicable, withheld, unknown), or text prepended by other:, or may be a URI link to a more detailed explanation.

When you are exchanging data, the role for which XML is commonly used, data sent to one recipient or for a given purpose may have content obscured that would be available to someone else who paid or had different authentication. Knowing the reason why content was missing can be very important.

Scientists also are concerned with why information is missing. For example, if it was dropped for quality reasons, they may want to see the original bad data.

995 is an error reported by the IO Completion Port. The error comes since you try to continue read from the socket when it has most likely been closed.

Receiving 0 bytes from EndRecieve means that the socket has been closed, as does most exceptions that EndRecieve will throw.

You need to start dealing with those situations.

Never ever ignore exceptions, they are thrown for a reason.

Update

There is nothing that says that the server does anything wrong. A connection can be lost for a lot of reasons such as idle connection being closed by a switch/router/firewall, shaky network, bad cables etc.

What I'm saying is that you MUST handle disconnections. The proper way of doing so is to dispose the socket and try to connect a new one at certain intervals.

As for the receive callback a more proper way of handling it is something like this (semi pseudo code):

public void OnDataReceived(IAsyncResult asyn)
{
    BLCommonFunctions.WriteLogger(0, "In :- OnDataReceived", ref swReceivedLogWriter, strLogPath, 0);

    try
    {
        SocketPacket client = (SocketPacket)asyn.AsyncState;

        int bytesReceived = client.thisSocket.EndReceive(asyn); //Here error is coming
        if (bytesReceived == 0)
        {
          HandleDisconnect(client);
          return;
        }
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }

    try
    {
        string strHEX = BLCommonFunctions.ByteArrToHex(theSockId.dataBuffer);                    

        //do your handling here
    }
    catch (Exception err)
    {
        // Your logic threw an exception. handle it accordinhly
    }

    try
    {
       client.thisSocket.BeginRecieve(.. all parameters ..);
    }
    catch (Exception err)
    {
       HandleDisconnect(client);
    }
}

the reason to why I'm using three catch blocks is simply because the logic for the middle one is different from the other two. Exceptions from BeginReceive/EndReceive usually indicates socket disconnection while exceptions from your logic should not stop the socket receiving.

The header just denotes what the content is encoded in. It is not necessarily possible to deduce the type of the content from the content itself, i.e. you can't necessarily just look at the content and know what to do with it. That's what HTTP headers are for, they tell the recipient what kind of content they're (supposedly) dealing with.

Content-type: application/json; charset=utf-8 designates the content to be in JSON format, encoded in the UTF-8 character encoding. Designating the encoding is somewhat redundant for JSON, since the default (only?) encoding for JSON is UTF-8. So in this case the receiving server apparently is happy knowing that it's dealing with JSON and assumes that the encoding is UTF-8 by default, that's why it works with or without the header.

Does this encoding limit the characters that can be in the message body?

No. You can send anything you want in the header and the body. But, if the two don't match, you may get wrong results. If you specify in the header that the content is UTF-8 encoded but you're actually sending Latin1 encoded content, the receiver may produce garbage data, trying to interpret Latin1 encoded data as UTF-8. If of course you specify that you're sending Latin1 encoded data and you're actually doing so, then yes, you're limited to the 256 characters you can encode in Latin1.

If your model is really "responsible" for the constants you should stick them there. You can create class methods to access them without creating a new object instance:

class Card < ActiveRecord::Base
  def self.colours
    ['white', 'blue']
  end
end

# accessible like this
Card.colours

Alternatively, you can create class variables and an accessor. This is however discouraged as class variables might act kind of surprising with inheritance and in multi-thread environments.

class Card < ActiveRecord::Base
  @@colours = ['white', 'blue'].freeze
  cattr_reader :colours
end

# accessible the same as above
Card.colours

The two options above allow you to change the returned array on each invocation of the accessor method if required. If you have true a truly unchangeable constant, you can also define it on the model class:

class Card < ActiveRecord::Base
  COLOURS = ['white', 'blue'].freeze
end

# accessible as
Card::COLOURS

You could also create global constants which are accessible from everywhere in an initializer like in the following example. This is probably the best place, if your colours are really global and used in more than one model context.

# put this into config/initializers/my_constants.rb
COLOURS = ['white', 'blue'].freeze

# accessible as a top-level constant this time
COLOURS

Note: when we define constants above, often we want to freeze the array. That prevents other code from later (inadvertently) modifying the array by e.g. adding a new element. Once an object is frozen, it can't be changed anymore.

all the above did not work when i used cloudflare, this one worked for me:

RewriteCond %{HTTP:X-Forwarded-Proto} =https
RewriteRule ^(.*)$ http://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

and this one definitely works without proxies in the way:

RewriteCond %{HTTPS} on
RewriteRule (.*) http://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

Instead of setting a fixed path try this in your post-build command-line first:

SET VCTargetsPath=$(VCTargetsPath)

The variable '$(VCTargetsPath)' seems to be a c++-related visual-studio-macro which is not shown in c#-sdk-projects as a macro but is still available there.

There's no built-in command for that because it's illegal. You can't modify the size of an array once declared.

What you're looking for is either std::vector to simulate a dynamic array, or better yet a std::string.

std::string first ("The dog jumps ");
std::string second ("over the log");
std::cout << first + second << std::endl;

I had fixed this problem by removing the .gradle folder

in windows: C:\Users{Logged in User}.gradle

To trim all trailing whitespace characters (I'm guessing that is actually your intent), the following is a pretty clean & concise way to do it.

Swift 5:

let trimmedString = string.replacingOccurrences(of: "\\s+$", with: "", options: .regularExpression)

Objective-C:

NSString *trimmedString = [string stringByReplacingOccurrencesOfString:@"\\s+$" withString:@"" options:NSRegularExpressionSearch range:NSMakeRange(0, string.length)];

One line, with a dash of regex.

See http://www.w3schools.com/tags/att_input_accept.asp:

The accept attribute is supported in all major browsers, except Internet Explorer and Safari. Definition and Usage

The accept attribute specifies the types of files that the server accepts (that can be submitted through a file upload).

Note: The accept attribute can only be used with <input type="file">.

Tip: Do not use this attribute as a validation tool. File uploads should be validated on the server.

Syntax <input accept="audio/*|video/*|image/*|MIME_type" />

Tip: To specify more than one value, separate the values with a comma (e.g. <input accept="audio/*,video/*,image/*" />.

i realize this post is several years old now, but sometimes certified newbies such as myself need a working example that is totally stripped down to the absolute most simplest form.

every simple socket.io example i could find involved http.createServer(). but what if you want to include a bit of socket.io magic in an existing webpage? here is the absolute easiest and smallest example i could come up with.

this just returns a string passed from the console UPPERCASED.

app.js

var http = require('http');

var app = http.createServer(function(req, res) {
        console.log('createServer');
});
app.listen(3000);

var io = require('socket.io').listen(app);


io.on('connection', function(socket) {
    io.emit('Server 2 Client Message', 'Welcome!' );

    socket.on('Client 2 Server Message', function(message)      {
        console.log(message);
        io.emit('Server 2 Client Message', message.toUpperCase() );     //upcase it
    });

});

index.html:

<!doctype html>
<html>
    <head>
        <script type='text/javascript' src='http://localhost:3000/socket.io/socket.io.js'></script>
        <script type='text/javascript'>
                var socket = io.connect(':3000');
                 // optionally use io('http://localhost:3000');
                 // but make *SURE* it matches the jScript src
                socket.on ('Server 2 Client Message',
                     function(messageFromServer)       {
                        console.log ('server said: ' + messageFromServer);
                     });

        </script>
    </head>
    <body>
        <h5>Worlds smallest Socket.io example to uppercase strings</h5>
        <p>
        <a href='#' onClick="javascript:socket.emit('Client 2 Server Message', 'return UPPERCASED in the console');">return UPPERCASED in the console</a>
                <br />
                socket.emit('Client 2 Server Message', 'try cut/paste this command in your console!');
        </p>
    </body>
</html>

to run:

npm init;  // accept defaults
npm  install  socket.io  http  --save ;
node app.js  &

use something like this port test to ensure your port is open.

now browse to http://localhost/index.html and use your browser console to send messages back to the server.

at best guess, when using http.createServer, it changes the following two lines for you:

<script type='text/javascript' src='/socket.io/socket.io.js'></script>
var socket = io();

i hope this very simple example spares my fellow newbies some struggling. and please notice that i stayed away from using "reserved word" looking user-defined variable names for my socket definitions.

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

This is actually redundant except in cases where you want to override the defaults. All of these settings are implied defaults.

You can verify that by checking your effective POM using this command

mvn help:effective-pom

    <finalName>name</finalName>
    <directory>target</directory>
    <outputDirectory>target/classes</outputDirectory>
    <testOutputDirectory>target/test-classes</testOutputDirectory>
    <sourceDirectory>src/main/java</sourceDirectory>
    <testSourceDirectory>src/test/java</testSourceDirectory>
    <resources>
        <resource>
            <directory>src/main/resources</directory>
        </resource>
    </resources>
    <testResources>
        <testResource>
            <directory>src/test/resources</directory>
        </testResource>
    </testResources>

For example, if i want to point to a different test resource path or resource path you should use this otherwise you don't.

    <resources>
        <resource>
            <directory>/home/josh/desktop/app_resources</directory>
        </resource>
    </resources>
    <testResources>
        <testResource>
            <directory>/home/josh/desktop/test_resources</directory>
        </testResource>
    </testResources>

See here for a similar post on using jQuery to clear forms: Resetting a multi-stage form with jQuery

You may also be running into an issue where the values are being repopulated by the struts value stack. In other words, you submit your form, do whatever in the action class, but do not clear the related field values in the action class. In this scenario the form would appear to maintain the values you previously submitted. If you are persisting these in some way, just null each field value in your action class after persisting and prior to returning SUCCESS.

Funny enough, a same problem I just met, and I get this work in following way:

combining with linux command ln , we can make thing a lot simper:

1. cd Proj/Client
2. ln -s ../Common ./

3. cd Proj/Server
4. ln -s ../Common ./

And, now if you want to import some_stuff from file: Proj/Common/Common.py into your file: Proj/Client/Client.py, just like this:

# in Proj/Client/Client.py
from Common.Common import some_stuff

And, the same applies to Proj/Server, Also works for setup.py process, a same question discussed here, hope it helps !

This is how I usually do it (sql server).

Create Table Master (
MasterID int identity(1,1) primary key,
Stuff varchar(10)
)
GO
Create Table Detail (
DetailID int identity(1,1) primary key,
MasterID int references Master, --use 'references'
Stuff varchar(10))
GO
Insert into Master values('value')
--(1 row(s) affected)
GO
Insert into Detail values (1, 'Value1') -- Works
--(1 row(s) affected)
insert into Detail values (2, 'Value2') -- Fails
--Msg 547, Level 16, State 0, Line 2
--The INSERT statement conflicted with the FOREIGN KEY constraint "FK__Detail__MasterID__0C70CFB4". 
--The conflict occurred in database "Play", table "dbo.Master", column 'MasterID'.
--The statement has been terminated.

As you can see the second insert into the detail fails because of the foreign key. Here's a good weblink that shows various syntax for defining FK during table creation or after.

http://www.1keydata.com/sql/sql-foreign-key.html

from operator import truediv

c = truediv(a, b)

where a is dividend and b is the divisor. This function is handy when quotient after division of two integers is a float.

the small one implement by the OS

<RatingBar
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    />

Simply as bellow;

$this->db->get('table_name')->num_rows();

This will get number of rows/records. however you can use search parameters as well;

$this->db->select('col1','col2')->where('col'=>'crieterion')->get('table_name')->num_rows();

However, it should be noted that you will see bad bad errors if applying as below;

$this->db->get('table_name')->result()->num_rows();

You can try this. but before you need to install psutil using sudo pip install psutil

import psutil
for proc in psutil.process_iter(attrs=['pid', 'name']):
    if 'ichat' in proc.info['name']:
        proc.kill()

This code works very fast. It comes from here

You can style it by the following way:

echo "<p style='color:red;'>" . $ip['cityName'] . "</p>";
echo "<p style='color:red;'>" . $ip['countryName'] . "</p>";

I had the same problem. It was because I had accidentally used a relative path with the symbolic link.

Are you sure you used full paths, e.g.:

ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/example.com.conf

Depending on the hibernate flush mode that you are using (AUTO is the default) save may or may not write your changes to the DB straight away. When you call saveAndFlush you are enforcing the synchronization of your model state with the DB.

If you use flush mode AUTO and you are using your application to first save and then select the data again, you will not see a difference in bahvior between save() and saveAndFlush() because the select triggers a flush first. See the documention.

Depending on what you want to do runnning it via a Proxy is not ideal. A transparent proxy might work ok as long as the packets do not get tampered with.

I am about to reverse the GPS data that gets transferred from the iPhone to the iPad on iOS 4.3.x to get to the the vanilla data the best way to get a clean Network Dump is to use "tcpdump" and/or "pirni" as already suggested.

In this particular case where we want the Tethered data it needs to be as transparent as possible. Obviously you need your phone to be JailBroken for this to work.

There's now a drop down (at least since VS 2017.3.5) where you can specifically select C++17. The available options are (under project > Properties > C/C++ > Language > C++ Language Standard)

• ISO C++14 Standard. msvc command line option: /std:c++14
• ISO C++17 Standard. msvc command line option: /std:c++17
• The latest draft standard. msvc command line option: /std:c++latest

(I bet, once C++20 is out and more fully supported by Visual Studio it will be /std:c++20)

This will print everything after each match, on that same line only:

perl -lne 'print $1 if /^potato:\s*(.*)/' file.txt

This will do the same, except it will also print all subsequent lines:

perl -lne 'if ($found){print} elsif (/^potato:\s*(.*)/){print $1; $found++}' file.txt

These command-line options are used:

• -n loop around each line of the input file
• -l removes newlines before processing, and adds them back in afterwards
• -e execute the perl code

Logical Processing Order of the SELECT statement

The following steps show the logical processing order, or binding order, for a SELECT statement. This order determines when the objects defined in one step are made available to the clauses in subsequent steps. For example, if the query processor can bind to (access) the tables or views defined in the FROM clause, these objects and their columns are made available to all subsequent steps. Conversely, because the SELECT clause is step 8, any column aliases or derived columns defined in that clause cannot be referenced by preceding clauses. However, they can be referenced by subsequent clauses such as the ORDER BY clause. Note that the actual physical execution of the statement is determined by the query processor and the order may vary from this list.

1. FROM
2. ON
3. JOIN
4. WHERE
5. GROUP BY
6. WITH CUBE or WITH ROLLUP
7. HAVING
8. SELECT
9. DISTINCT
10. ORDER BY
11. TOP

In my case. I installed the release-version app. And after uninstall the app from my device. Thing works fine.

If you're a fan of NumPyish syntax, then there's tensor.shape.

In [3]: ar = torch.rand(3, 3)

In [4]: ar.shape
Out[4]: torch.Size([3, 3])

# method-1
In [7]: list(ar.shape)
Out[7]: [3, 3]

# method-2
In [8]: [*ar.shape]
Out[8]: [3, 3]

# method-3
In [9]: [*ar.size()]
Out[9]: [3, 3]

P.S.: Note that tensor.shape is an alias to tensor.size(), though tensor.shape is an attribute of the tensor in question whereas tensor.size() is a function.

From Artima's Typing: Strong vs. Weak, Static vs. Dynamic article:

strong typing prevents mixing operations between mismatched types. In order to mix types, you must use an explicit conversion

weak typing means that you can mix types without an explicit conversion

In the Pascal Costanza's paper, Dynamic vs. Static Typing — A Pattern-Based Analysis (PDF), he claims that in some cases, static typing is more error-prone than dynamic typing. Some statically typed languages force you to manually emulate dynamic typing in order to do "The Right Thing". It's discussed at Lambda the Ultimate.

Changed my entry to

entry: path.resolve(__dirname, './src/js/index.js'),

and it worked.

This is a stab in the dark, but maybe do you need to wrap your JSON arguments; like say something like this:

data: "{'Ids':[{'Id1':'2'},{'Id2':'2'}]}"

Make sure your JSON is properly formed?

For Java 11 you can use new HTTP client:

 HttpClient client = HttpClient.newHttpClient();
    HttpRequest request = HttpRequest.newBuilder()
        .uri(URI.create("http://localhost/api"))
        .header("Content-Type", "application/json")
        .POST(ofInputStream(() -> getClass().getResourceAsStream(
            "/some-data.json")))
        .build();

    client.sendAsync(request, BodyHandlers.ofString())
        .thenApply(HttpResponse::body)
        .thenAccept(System.out::println)
        .join();

You can use publisher from InputStream, String, File. Converting JSON to the String or IS you can with Jackson.

I take it you are asking what the return value is in the comparison function.

If the dates are equal then returning NSOrderedSame

If ascending ( 2nd arg > 1st arg ) return NSOrderedAscending

If descending ( 2nd arg < 1st arg ) return NSOrderedDescending

According to the PHP Documentation json_decode function has a parameter named assoc which convert the returned objects into associative arrays

 mixed json_decode ( string $json [, bool $assoc = FALSE ] )

Since assoc parameter is FALSE by default, You have to set this value to TRUE in order to retrieve an array.

Examine the below code for an example implication:

$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json));
var_dump(json_decode($json, true));

which outputs:

object(stdClass)#1 (5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

array(5) {
    ["a"] => int(1)
    ["b"] => int(2)
    ["c"] => int(3)
    ["d"] => int(4)
    ["e"] => int(5)
}

change PYTHONHOME to the parent folder of the bin file of python, like /usr,which is the parent folder of /usr/bin.

Try to include these lines on your code, after mych.Visible = true;:

ChartArea chA = new ChartArea();
mych.ChartAreas.Add(chA);

find supports -delete operation, so:

find /base/dir/* -ctime +10 -delete;

I think there's a catch that the files need to be 10+ days older too. Haven't tried, someone may confirm in comments.

The most voted solution here is missing -maxdepth 0 so it will call rm -rf for every subdirectory, after deleting it. That doesn't make sense, so I suggest:

find /base/dir/* -maxdepth 0  -type d -ctime +10 -exec rm -rf {} \;

The -delete solution above doesn't use -maxdepth 0 because find would complain the dir is not empty. Instead, it implies -depth and deletes from the bottom up.

Difference between show() and css({'display':'block'})

Assuming you have this at the beginning:

<span id="thisElement" style="display: none;">Foo</span>

when you call:

$('#thisElement').show();

you will get:

<span id="thisElement" style="">Foo</span>

while:

$('#thisElement').css({'display':'block'});

does:

<span id="thisElement" style="display: block;">Foo</span>

so, yes there's a difference.

Difference between hide() and css({'display':'none'})

same as above but change these into hide() and display':'none'......

Another difference When .hide() is called the value of the display property is saved in jQuery's data cache, so when .show() is called, the initial display value is restored!

In ASP.NET MVC 3 Preview1 you can import a namespace on all your razor views with this code in Global.asax.cs

Microsoft.WebPages.Compilation.CodeGeneratorSettings.AddGlobalImport("Namespace.Namespace");

I hope in RTM this gets done through Web.config section.

Try this,

 $('.nav-list li').click(function() {

    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

In your context $(this) will points to the UL element not the Li. Hence you are not getting the expected results.

Use the wildcard "#" but beware that at some point you will have to somehow understand the data passing through the bus!

Using bash "here string":

$ fspec="/exp/home1/abc.txt" 
$ tr  "/"  "\n"  <<< $fspec | tail -1
abc.txt
$ filename=$(tr  "/"  "\n"  <<< $fspec | tail -1)
$ echo $filename
abc.txt

The benefit of the "here string" is that it avoids the need/overhead of running an echo command. In other words, the "here string" is internal to the shell. That is:

$ tr <<< $fspec

as opposed to:

$ echo $fspec | tr

Improving the solution to detect circle with circle collision detection given within the question:

float dx = circle1.x - circle2.x,
      dy = circle1.y - circle2.y,
       r = circle1.r + circle2.r;
return (dx * dx + dy * dy <= r * r);

It avoids the unnecessary "if with two returns" and the use of more variables than necessary.

A JUnit4 test with Autowired and bean mocking (Mockito):

// JUnit starts spring context
@RunWith(SpringRunner.class)
// spring load context configuration from AppConfig class
@ContextConfiguration(classes = AppConfig.class)
// overriding some properties with test values if you need
@TestPropertySource(properties = {
        "spring.someConfigValue=your-test-value",
})
public class PersonServiceTest {

    @MockBean
    private PersonRepository repository;

    @Autowired
    private PersonService personService; // uses PersonRepository    

    @Test
    public void testSomething() {
        // using Mockito
        when(repository.findByName(any())).thenReturn(Collection.emptyList());
        Person person = new Person();
        person.setName(null);

        // when
        boolean found = personService.checkSomething(person);

        // then
        assertTrue(found, "Something is wrong");
    }
}

Solution using 1 variable (Only p):

typedef unsigned long AddressType;

#define A (*( AddressType* )&p )
#define B (*( AddressType* )&first->link->link )
#define C (*( AddressType* )&first->link )

/* Reversing linked list */
p = first;

while( first->link )
{
    A = A + B + C;
    B = A - B - C;
    A = A - B;
    C = A - C;
    A = A - C;
}

first = p;

What I use everywhere :

 Runtime.getRuntime().exec("pm clear me.myapp");

Executing above piece of code closes application and removes all databases and shared preferences

Just a little expansion to Nathan's Linq Expression solution. Use multi generic param so that the property doesn't limited to string.

void GetString<TClass, TProperty>(string input, TClass outObj, Expression<Func<TClass, TProperty>> outExpr)
{
    if (!string.IsNullOrEmpty(input))
    {
        var expr = (MemberExpression) outExpr.Body;
        var prop = (PropertyInfo) expr.Member;
        if (!prop.GetValue(outObj).Equals(input))
        {
            prop.SetValue(outObj, input, null);
        }
    }
}

Add the below code in your page. Trust me, no changes made to button events, to disable/enable button simply add/remove the button class in Javascript.

Method 1

 <asp Button ID="btnSave" CssClass="disabledContent" runat="server" />

<style type="text/css">
    .disabledContent 
    {
        cursor: not-allowed;
        background-color: rgb(229, 229, 229) !important;
    }

    .disabledContent > * 
    {
        pointer-events:none;
    }
</style>

Method 2

<asp Button ID="btnSubmit" CssClass="btn-disable" runat="server" />

<style type="text/css">
    .btn-disable
        {
        cursor: not-allowed;
        pointer-events: none;

        /*Button disabled - CSS color class*/
        color: #c0c0c0;
        background-color: #ffffff;

        }
</style>

At least for the Windows binary version I tested, (the Generic Win64 no-SSL binary, currently based on 7.33.0), you are subject to limitations in how the command line arguments are being parsed. The answer by xmas describes the correct syntax in that setting, which also works in a batch file. Using the example provided:

curl -i -X POST -H "Content-Type: application/json" -d "{""data1"":""data goes here"",""data2"":""data2 goes here""}" http:localhost/path/to/api

A cleaner alternative to avoid having to deal with escaped characters, which is dependent upon whatever library is used to parse the command line, is to have your standard json format text in a separate file:

curl -i -X POST -H "Content-Type: application/json" -d "@body.json" http:localhost/path/to/api

In case you are using application.yml add the Following lines to it

server:
     port: 9000

and of course 0 for random port.

ArrayList implements the List Interface.

If you look at the Javadoc for List at the contains method you will see that it uses the equals() method to evaluate if two objects are the same.

Use the following line in your code:

TextView.setSelected(true);

You have a ; at the end of the if. Change:

  if (fp == NULL);
  return 0;

to

  if (fp == NULL) 
    return 0;

The short version

You only need BOOST_ROOT, but you're going to want to disable searching the system for your local Boost if you have multiple installations or cross-compiling for iOS or Android. In which case add Boost_NO_SYSTEM_PATHS is set to false.

set( BOOST_ROOT "" CACHE PATH "Boost library path" )
set( Boost_NO_SYSTEM_PATHS on CACHE BOOL "Do not search system for Boost" )

Normally this is passed on the CMake command-line using the syntax -D<VAR>=value.

The longer version

Officially speaking the FindBoost page states these variables should be used to 'hint' the location of Boost.

This module reads hints about search locations from variables:

BOOST_ROOT             - Preferred installation prefix
 (or BOOSTROOT)
BOOST_INCLUDEDIR       - Preferred include directory e.g. <prefix>/include
BOOST_LIBRARYDIR       - Preferred library directory e.g. <prefix>/lib
Boost_NO_SYSTEM_PATHS  - Set to ON to disable searching in locations not
                         specified by these hint variables. Default is OFF.
Boost_ADDITIONAL_VERSIONS
                       - List of Boost versions not known to this module
                         (Boost install locations may contain the version)

This makes a theoretically correct incantation:

cmake -DBoost_NO_SYSTEM_PATHS=TRUE \
      -DBOOST_ROOT=/path/to/boost-dir

When you compile from source

include( ExternalProject )

set( boost_URL "http://sourceforge.net/projects/boost/files/boost/1.63.0/boost_1_63_0.tar.bz2" )
set( boost_SHA1 "9f1dd4fa364a3e3156a77dc17aa562ef06404ff6" )
set( boost_INSTALL ${CMAKE_CURRENT_BINARY_DIR}/third_party/boost )
set( boost_INCLUDE_DIR ${boost_INSTALL}/include )
set( boost_LIB_DIR ${boost_INSTALL}/lib )

ExternalProject_Add( boost
        PREFIX boost
        URL ${boost_URL}
        URL_HASH SHA1=${boost_SHA1}
        BUILD_IN_SOURCE 1
        CONFIGURE_COMMAND
        ./bootstrap.sh
        --with-libraries=filesystem
        --with-libraries=system
        --with-libraries=date_time
        --prefix=<INSTALL_DIR>
        BUILD_COMMAND
        ./b2 install link=static variant=release threading=multi runtime-link=static
        INSTALL_COMMAND ""
        INSTALL_DIR ${boost_INSTALL} )

set( Boost_LIBRARIES
        ${boost_LIB_DIR}/libboost_filesystem.a
        ${boost_LIB_DIR}/libboost_system.a
        ${boost_LIB_DIR}/libboost_date_time.a )
message( STATUS "Boost static libs: " ${Boost_LIBRARIES} )

Then when you call this script you'll need to include the boost.cmake script (mine is in the a subdirectory), include the headers, indicate the dependency, and link the libraries.

include( boost )
include_directories( ${boost_INCLUDE_DIR} )
add_dependencies( MyProject boost )
target_link_libraries( MyProject
                       ${Boost_LIBRARIES} )

Keypress event is deprecated, You should use Keydown event instead.

https://developer.mozilla.org/en-US/docs/Web/API/Document/keypress_event

handleKeyDown(event) {
    if(event.keyCode === 13) { 
        console.log('Enter key pressed')
  }
}

render() { 
    return <input type="text" onKeyDown={this.handleKeyDown} /> 
}

looks like you have maven project and so resources are in classpath by

go for

A little late to the game on this post, but I found this way to be pretty flexible / efficient

select 
    s1.id
    ,s1.name
    ,s1.city 
from 
    stuff s1
    ,stuff s2
Where
    s1.id <> s2.id
    and s1.name = s2.name
    and s1.city = s2.city

I've tried lots of different answers in different forums. I guess it depends on the machine your developing. But I haved used the statement

ax.lines = []

and works perfectly. I don't use cla() cause it deletes all the definitions I've made to the plot

Ex.

pylab.setp(_self.ax.get_yticklabels(), fontsize=8)

but I've tried deleting the lines many times. Also using the weakref library to check the reference to that line while I was deleting but nothing worked for me.

Hope this works for someone else =D

Using appendEncodePath() could save you multiple lines than appendPath(), the following code snippet builds up this url: http://api.openweathermap.org/data/2.5/forecast/daily?zip=94043

Uri.Builder urlBuilder = new Uri.Builder();
urlBuilder.scheme("http");
urlBuilder.authority("api.openweathermap.org");
urlBuilder.appendEncodedPath("data/2.5/forecast/daily");

Ademar's solution can be improved by leveraging JavaScriptSerializer's Serialize method to provide implicit conversion of the object to JSON.

Additionally, it is possible to leverage the using statement's default functionality in order to omit explicitly calling Flush and Close.

var httpWebRequest = (HttpWebRequest)WebRequest.Create("http://url");
httpWebRequest.ContentType = "application/json";
httpWebRequest.Method = "POST";

using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
{
    string json = new JavaScriptSerializer().Serialize(new
                {
                    user = "Foo",
                    password = "Baz"
                });

    streamWriter.Write(json);
}

var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
{
    var result = streamReader.ReadToEnd();
}

If you already have to hide Some columns, like I hide last name column. I just had to concatenate fname , lname , So i made query but hide that column from front end. The modifications in Disable sorting in such situation are :

    "aoColumnDefs": [
        { 'bSortable': false, 'aTargets': [ 3 ] },
        {
            "targets": [ 4 ],
            "visible": false,
            "searchable": true
        }
    ],

Notice that I had Hiding functionality here

    "columnDefs": [
            {
                "targets": [ 4 ],
                "visible": false,
                "searchable": true
            }
        ],

Then I merged it into "aoColumnDefs"

See following snippet :

$(document).on("click", "a.deleteText", function() {_x000D_
    if (confirm('Are you sure ?')) {_x000D_
        $(this).prev('span.text').remove();_x000D_
    }_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<div class="container">_x000D_
    <span class="text">some text</span>_x000D_
    <a href="#" class="deleteText"><span class="delete-icon"> x Delete </span></a>_x000D_
</div>

The key trick in both those solutions is to create an array instance with a given size (one more than the desired length), and then to immediately call the join() method to make a string. The join() method is passed the padding string (spaces probably). Since the array is empty, the empty cells will be rendered as empty strings during the process of joining the array into one result string, and only the padding will remain. It's a really nice technique.

str = "Tue, 10 Aug 2010 01:20:19 -0400 (EDT)"
str.to_date
=> Tue, 10 Aug 2010

if (window.performance && window.performance.navigation.type == window.performance.navigation.TYPE_BACK_FORWARD) {

}

This is the only one solution that worked for me (it's not a onepage website). It's working with Chrome, Firefox and Safari.

As of Mongoose 3.8.x:

model.find({ ... }).sort({ field : criteria}).exec(function(err, model){ ... });

Where:

criteria can be asc, desc, ascending, descending, 1, or -1

Note: Use quotation marks or double quote

use "asc", "desc", "ascending", "descending", 1, or -1

The Mandelbrot Set can be presented in a way that isn't terribly complex, for example in Java below:

public class MiniMandelbrot {
    public static void main(String[] args) {
        int[] rgbArray = new int[256 * 256];
        for (int y=0; y<256; y++) {
            for (int x=0; x<256; x++) {
                double cReal=x/64.0-2.0, cImaginary=y/64.0-2.0;
                double zReal=0.0, zImaginary=0.0, zRealSquared=0.0, zImaginarySquared=0.0;
                int i;
                for (i = 0; (i < 63) && (zRealSquared + zImaginarySquared < 4.0); i++) {
                    zImaginary = (zReal * zImaginary) + (zReal * zImaginary) + cImaginary;
                    zReal = zRealSquared - zImaginarySquared - cReal;
                    zImaginarySquared = zImaginary * zImaginary;
                    zRealSquared = zReal * zReal;
                }
                rgbArray[x+y*256] = i * 0x040404;
            }
        }
        java.awt.image.BufferedImage bufferedImage = new java.awt.image.BufferedImage(256, 256, 1);
        bufferedImage.setRGB(0, 0, 256, 256, rgbArray, 0, 256);
        javax.swing.JOptionPane.showMessageDialog(null, new javax.swing.ImageIcon(bufferedImage), "The Mandelbrot Set", -1);
    }
}

At this time, there is no need for the script tag inside the iframe. This works for me (tested in Chrome, Firefox, IE11 and node-webkit 0.12):

<script>
window.onload = function() {
    var body = 'dddddd';
    var newWin = document.getElementById('printf').contentWindow;
    newWin.document.write(body);
    newWin.document.close(); //important!
    newWin.focus(); //IE fix
    newWin.print();
}
</script>

<iframe id="printf"></iframe>

Thanks to all answers, save my day.

You may be able to query this from the ALL_CONSTRAINTS view:

SELECT table_name
FROM ALL_CONSTRAINTS
WHERE constraint_type = 'R' -- "Referential integrity"
  AND r_constraint_name IN
    ( SELECT constraint_name
      FROM ALL_CONSTRAINTS
      WHERE table_name = 'EMP'
        AND constraint_type IN ('U', 'P') -- "Unique" or "Primary key"
    );

I use $arr = array_merge($arr); to rebase an array. Simple and straightforward.

The problem is you defined myList from main.py, but subfile.py needs to use it. Here is a clean way to solve this problem: move all globals to a file, I call this file settings.py. This file is responsible for defining globals and initializing them:

# settings.py

def init():
    global myList
    myList = []

Next, your subfile can import globals:

# subfile.py

import settings

def stuff():
    settings.myList.append('hey')

Note that subfile does not call init()— that task belongs to main.py:

# main.py

import settings
import subfile

settings.init()          # Call only once
subfile.stuff()         # Do stuff with global var
print settings.myList[0] # Check the result

This way, you achieve your objective while avoid initializing global variables more than once.

I'd go with

private void Form1_Resize(object sender, EventArgs e)
{
     if (FormWindowState.Minimized == this.WindowState)
     {
          notifyIcon1.Visible = true;
          notifyIcon1.ShowBalloonTip(500);
          this.Hide();    
     }
     else if (FormWindowState.Normal == this.WindowState)
     {
          notifyIcon1.Visible = false;
     }
}

private void notifyIcon1_MouseDoubleClick(object sender, MouseEventArgs e)
{
     this.Show();
     this.WindowState = FormWindowState.Normal;
}

A map will not keep insertion order. Use *(myMap.begin()) to get the value of the first pair (the one with the smallest key when ordered).

You could also do myMap.begin()->first to get the key and myMap.begin()->second to get the value.

Alternatively to the suggested 3 methods you can try let which carries out arithmetic operations on variables as follows:

let COUNT=$FIRSTV-$SECONDV

or

let COUNT=FIRSTV-SECONDV

In C++11:

static const int a[] = {10, 20, 30};
vector<int> vec (begin(a), end(a));

To expand on the "use JAXB" comments above,

In Windows "%java_home%\bin\xjc" -p [your namespace] [xsd_file].xsd

e.g., "%java_home%\bin\xjc" -p com.mycompany.quickbooks.obj quickbooks.xsd

Wait a bit, and if you had a well-formed XSD file, you will get some well-formed Java classes

Just do

if (Attachment != null  && Attachment.Length > 0)

From && Operator

The conditional-AND operator (&&) performs a logical-AND of its bool operands, but only evaluates its second operand if necessary.

I wrote this code in my .bashrc

In a folder like "/home/<user>/example-files" having this structure:

• /home/<user>/example-files:
  • file1.txt
  • file2.txt
  • file3.pdf
  • file4.csv

The commands would behave like this:

~$ find-text

I hit this error because I was specifying a label attribute in my geom (geom_text) but was specifying a color in the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# don't do this!
ggplot(df, aes(x=V6, y=V1, color=V1)) +
  geom_text(angle=45, label=df$V1, size=2)

To fix this, I just moved the label attribute out of the geom and into the top level aes:

df <- read.table('match-stats.tsv', sep='\t')
library(ggplot2)

# do this!
ggplot(df, aes(x=V6, y=V1, color=V1, label=V1)) +
  geom_text(angle=45, size=2)

You're probably talking about unobtrusive Javascript, which would look like this:

<a href="#" id="someLink">link</a>

with the logic in a central javascript file looking something like this:

$('#someLink').click(function(){
    popup('/map/', 300, 300, 'map'); 
    return false;
});

The advantages are

• behaviour (Javascript) is separated from presentation (HTML)
• no mixing of languages
• you're using a javascript framework like jQuery that can handle most cross-browser issues for you
• You can add behaviour to a lot of HTML elements at once without code duplication

//works in IE, not sure about other browsers...

alert(classes[x].style.cssText);

I wrote this code before a final attempt with Google and finding this page, so I thought I'd share it. It is basically an optimized version of Kisielewicz answer. I looked into the Barycentric method also but judging from the Wikipedia article I have a hard time seeing how it is more efficient (I'm guessing there is some deeper equivalence). Anyway, this algorithm has the advantage of not using division; a potential problem is the behavior of the edge detection depending on orientation.

bool intpoint_inside_trigon(intPoint s, intPoint a, intPoint b, intPoint c)
{
    int as_x = s.x-a.x;
    int as_y = s.y-a.y;

    bool s_ab = (b.x-a.x)*as_y-(b.y-a.y)*as_x > 0;

    if((c.x-a.x)*as_y-(c.y-a.y)*as_x > 0 == s_ab) return false;

    if((c.x-b.x)*(s.y-b.y)-(c.y-b.y)*(s.x-b.x) > 0 != s_ab) return false;

    return true;
}

In words, the idea is this: Is the point s to the left of or to the right of both the lines AB and AC? If true, it can't be inside. If false, it is at least inside the "cones" that satisfy the condition. Now since we know that a point inside a trigon (triangle) must be to the same side of AB as BC (and also CA), we check if they differ. If they do, s can't possibly be inside, otherwise s must be inside.

Some keywords in the calculations are line half-planes and the determinant (2x2 cross product). Perhaps a more pedagogical way is probably to think of it as a point being inside iff it's to the same side (left or right) to each of the lines AB, BC and CA. The above way seemed a better fit for some optimization however.

XML Layout: declare WebView instead of TextView

<WebView
 android:id="@+id/textContent"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content" />

Java code: set text data to WebView

WebView view = (WebView) findViewById(R.id.textContent);
String text;
text = "<html><body><p align=\"justify\">";
text+= "This is the text will be justified when displayed!!!";
text+= "</p></body></html>";
view.loadData(text, "text/html", "utf-8");

This may Solve your problem. Its Fully worked for me.

With Java:

For int values:

public static int[] primeFactors(int value) {
    int[] a = new int[31];
    int i = 0, j;
    int num = value;
    while (num % 2 == 0) {
        a[i++] = 2;
        num /= 2;
    }
    j = 3;
    while (j <= Math.sqrt(num) + 1) {
        if (num % j == 0) {
            a[i++] = j;
            num /= j;
        } else {
            j += 2;
        }
    }
    if (num > 1) {
        a[i++] = num;
    }
    int[] b = Arrays.copyOf(a, i);
    return b;
}

For long values:

static long[] getFactors(long value) {
    long[] a = new long[63];
    int i = 0;
    long num = value;
    while (num % 2 == 0) {
        a[i++] = 2;
        num /= 2;
    }
    long j = 3;
    while (j <= Math.sqrt(num) + 1) {
        if (num % j == 0) {
            a[i++] = j;
            num /= j;
        } else {
            j += 2;
        }
    }
    if (num > 1) {
        a[i++] = num;
    }
    long[] b = Arrays.copyOf(a, i);
    return b;
}

Use below method:

private Drawable getColoredArrow() {
    Drawable arrowDrawable = getResources().getDrawable(R.drawable.abc_ic_ab_back_mtrl_am_alpha);
    Drawable wrapped = DrawableCompat.wrap(arrowDrawable);

    if (arrowDrawable != null && wrapped != null) {
        // This should avoid tinting all the arrows
        arrowDrawable.mutate();
        DrawableCompat.setTint(wrapped, Color.GRAY);
    }

    return wrapped;
}

Now you can set the drawable with:

getSupportActionBar().setHomeAsUpIndicator(getColoredArrow());

style={{ backgroundImage: "none" }}

Only this worked for me

This worked for me.

/bookstore/book[@location='US'][1] works only with simple structure.

Add a bit more structure and things break.

With-

<bookstore>
 <category>
  <book location="US">A1</book>
  <book location="FIN">A2</book>
 </category>
 <category>
  <book location="FIN">B1</book>
  <book location="US">B2</book>
 </category>
</bookstore> 

/bookstore/category/book[@location='US'][1] yields

<book location="US">A1</book>
<book location="US">B2</book>

not "the first node that matches a more complicated condition". /bookstore/category/book[@location='US'][2] returns nothing.

With parentheses you can get the result the original question was for:

(/bookstore/category/book[@location='US'])[1] gives

<book location="US">A1</book>

and (/bookstore/category/book[@location='US'])[2] works as expected.

The double underscore. It mangles the name in such a way that it can't be accessed simply through __fieldName from outside the class, which is what you want to begin with if they're to be private. (Though it's still not very hard to access the field.)

class Foo:
    def __init__(self):
        self.__privateField = 4;
        print self.__privateField # yields 4 no problem

foo = Foo()
foo.__privateField
# AttributeError: Foo instance has no attribute '__privateField'

It will be accessible through _Foo__privateField instead. But it screams "I'M PRIVATE DON'T TOUCH ME", which is better than nothing.

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

Also check to see if you are missing the www in the url which was on my case

i was testing on http://www.mywebsite.com and in the facebook app i had set http://mywebsite.com

System.String is immutable. When we modify the value of a string variable then a new memory is allocated to the new value and the previous memory allocation released. System.StringBuilder was designed to have concept of a mutable string where a variety of operations can be performed without allocation separate memory location for the modified string.

//String to Date Convert

var dateString = "2014-01-12"
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd"
let s = dateFormatter.dateFromString(dateString)
println(s)


//CONVERT FROM NSDate to String  

let date = NSDate()
var dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd" 
var dateString = dateFormatter.stringFromDate(date)
println(dateString)  

I have made this program and here is the bit of code that actually calculates the check digit in my program

    #Get the 10 digit number
    number=input("Please enter ISBN number: ")

    #Explained below
    no11 = (((int(number[0])*11) + (int(number[1])*10) + (int(number[2])*9) + (int(number[3])*8) 
           + (int(number[4])*7) + (int(number[5])*6) + (int(number[6])*5) + (int(number[7])*4) +
           (int(number[8])*3) + (int(number[9])*2))/11)

    #Round to 1 dp
    no11 = round(no11, 1)

    #explained below
    no11 = str(no11).split(".")

    #get the remainder and check digit
    remainder = no11[1]
    no11 = (11 - int(remainder))

    #Calculate 11 digit ISBN
    print("Correct ISBN number is " + number + str(no11))

Its a long line of code, but it splits the number up, multiplies the digits by the appropriate amount, adds them together and divides them by 11, in one line of code. The .split() function just creates a list (being split at the decimal) so you can take the 2nd item in the list and take that from 11 to find the check digit. This could also be made even more efficient by changing these two lines:

    remainder = no11[1]
    no11 = (11 - int(remainder))

To this:

    no11 = (11 - int(no11[1]))

Hope this helps :)

Another tool you can use is registry-cli. For example, this command:

registry.py -l "login:password" -r https://your-registry.example.com --delete

will delete all but the last 10 images.

To remove - Can't perform a React state update on an unmounted component warning, use componentDidMount method under a condition and make false that condition on componentWillUnmount method. For example : -

class Home extends Component {
  _isMounted = false;

  constructor(props) {
    super(props);

    this.state = {
      news: [],
    };
  }

  componentDidMount() {
    this._isMounted = true;

    ajaxVar
      .get('https://domain')
      .then(result => {
        if (this._isMounted) {
          this.setState({
            news: result.data.hits,
          });
        }
      });
  }

  componentWillUnmount() {
    this._isMounted = false;
  }

  render() {
    ...
  }
}

This is my solution for the problem. This is controller with 2 action methods

public class FeedbackController : Controller
{
public ActionResult Index()
{
   var feedbacks =dataFromSomeSource.getData;
   return View(feedbacks);
}

[System.Web.Mvc.HttpDelete]
[System.Web.Mvc.Authorize(Roles = "admin")]
public ActionResult Delete([FromBody]int id)
{
   return RedirectToAction("Index");
}
}

In View I render construct following structure.

<html>
..
<script src="~/Scripts/bootbox.min.js"></script>
<script>
function confirmDelete(id) {
  bootbox.confirm('@Resources.Resource.AreYouSure', function(result) {
    if (result) {
      document.getElementById('idField').value = id;
      document.getElementById('myForm').submit();
    }
  }.bind(this));
}
</script>

@using (Html.BeginForm("Delete", "Feedback", FormMethod.Post, new { id = "myForm" }))
{
  @Html.HttpMethodOverride(HttpVerbs.Delete)
  @Html.Hidden("id",null,new{id="idField"})
  foreach (var feedback in @Model)
  {
   if (User.Identity.IsAuthenticated && User.IsInRole("admin"))
   {
    @Html.ActionLink("Delete Item", "", new { id = @feedback.Id }, new { onClick = "confirmDelete("+feedback.Id+");return false;" })
   }
  }
...
</html>

Point of interest in Razor View:

1. JavaScript function confirmDelete(id) which is called when the link generated with @Html.ActionLink is clicked;

2. confirmDelete() function required id of item being clicked. This item is passed from onClick handler confirmDelete("+feedback.Id+");return false; Pay attention handler returns false to prevent default action - which is get request to target. OnClick event for buttons could be attached with jQuery for all buttons in the list as alternative (probably it will be even better, as it will be less text in the HTML page and data could be passed via data- attribute).

3. Form has id=myForm, in order to find it in confirmDelete().

4. Form includes @Html.HttpMethodOverride(HttpVerbs.Delete) in order to use the HttpDelete verb, as action marked with the HttpDeleteAttribute.

5. In the JS function I do use action confirmation (with help of external plugin, but standard confirm works fine too. Don't forget to use bind() in call back or var that=this (whatever you prefer).

6. Form has a hidden element with id='idField' and name='id'. So before the form is submitted after confirmation (result==true), the value of the hidden element is set to value passed argument and browser will submit data to controller like this:

Request URL:http://localhost:38874/Feedback/Delete

Request Method:POST Status Code:302 Found

Response Headers

Location:/Feedback Host:localhost:38874 Form Data X-HTTP-Method-Override:DELETE id:5

As you see it is POST request with X-HTTP-Method-Override:DELETE and data in body set to "id:5". Response has 302 code which redirect to Index action, by this you refresh your screen after delete.

I recommend the Boost.Random library, it's super detailed and well-documented, lets you explicitly specify what distribution you want, and in non-cryptographic scenarios can actually outperform a typical C library rand implementation.

To change the character set encoding to UTF-8 follow simple steps in PHPMyAdmin

1. Select your Database

2. Go To Operations

3. In operations tab, on the bottom collation drop down menu, select you desire encoding i.e(utf8_general_ci), and also check the checkbox (1)change all table collations, (2) Change all tables columns collations. and hit Go.

A procedure for dividing integers that uses shifts and adds can be derived in straightforward fashion from decimal longhand division as taught in elementary school. The selection of each quotient digit is simplified, as the digit is either 0 and 1: if the current remainder is greater than or equal to the divisor, the least significant bit of the partial quotient is 1.

Just as with decimal longhand division, the digits of the dividend are considered from most significant to least significant, one digit at a time. This is easily accomplished by a left shift in binary division. Also, quotient bits are gathered by left shifting the current quotient bits by one position, then appending the new quotient bit.

In a classical arrangement, these two left shifts are combined into left shifting of one register pair. The upper half holds the current remainder, the lower half initial holds the dividend. As the dividend bits are transferred to the remainder register by left shift, the unused least significant bits of the lower half are used to accumulate the quotient bits.

Below is x86 assembly language and C implementations of this algorithm. This particular variant of a shift & add division is sometimes referred to as the "no-performing" variant, as the subtraction of the divisor from the current remainder is not performed unless the remainder is greater than or equal to the divisor. In C, there is no notion of the carry flag used by the assembly version in the register pair left shift. Instead, it is emulated, based on the observation that the result of an addition modulo 2ⁿ can be smaller that either addend only if there was a carry out.

You can simply go to Menu > All Programs > Visual Studio 2013. Select the folder link "Visual Studio Tools". This will open the folder. There is bunch of shortcuts for command prompt which you can use. They worked perfectly for me.

I think the trick here might be there are different versions for different processors, hence they put them all together.

You are asking to initialize four variables using a single float object, which of course is not iterable. You can do -

1. grade_1, grade_2, grade_3, grade_4 = [0.0 for _ in range(4)]
2. grade_1 = grade_2 = grade_3 = grade_4 = 0.0

Unless you want to initialize them with different values of course.

In Active Directory environment, it's important to know:

• All member machines synchronizes with any domain controller.

• In a domain, all domain controllers synchronize from the PDC Emulator (PDCe) of that domain.

• The PDC Emulator of a domain should synchronize with local or NTP.

It's important to consider this when setting the time in vmware or configuring the time sync.

I had this issue in VS 2015. The following solved it for me:

Find "webpages:Version" in the appsettings and update it to version 3.0.0.0. My web.config had

<add key="webpages:Version" value="2.0.0.0" />

and I updated it to

<add key="webpages:Version" value="3.0.0.0" />

Take a look into file-regex

let findFiles = require('file-regex')
let pattern = '\.js'

findFiles(__dirname, pattern, (err, files) => {  
   console.log(files);
})

This above snippet would print all the js files in the current directory.
