Their are two methods you can use to pass an integer. One is as shown below.

A.class

Intent myIntent = new Intent(A.this, B.class);
myIntent.putExtra("intVariableName", intValue);
startActivity(myIntent);

B.class

Intent intent = getIntent();
int intValue = intent.getIntExtra("intVariableName", 0);

The other method converts the integer to a string and uses the following code.

A.class

Intent intent = new Intent(A.this, B.class);
Bundle extras = new Bundle();
extras.putString("StringVariableName", intValue + "");
intent.putExtras(extras);
startActivity(intent);

The code above will pass your integer value as a string to class B. On class B, get the string value and convert again as an integer as shown below.

B.class

   Bundle extras = getIntent().getExtras();
   String stringVariableName = extras.getString("StringVariableName");
   int intVariableName = Integer.parseInt(stringVariableName);

Unfortunately, you need to manually fire the change event. And using the Event Constructor will be the best solution.

var select = document.querySelector('#sel'),_x000D_
    input = document.querySelector('input[type="button"]');_x000D_
select.addEventListener('change',function(){_x000D_
    alert('changed');_x000D_
});_x000D_
input.addEventListener('click',function(){_x000D_
    select.value = 2;_x000D_
    select.dispatchEvent(new Event('change'));_x000D_
});

<select id="sel" onchange='alert("changed")'>_x000D_
  <option value='1'>One</option>_x000D_
  <option value='2'>Two</option>_x000D_
  <option value='3' selected>Three</option>_x000D_
</select>_x000D_
<input type="button" value="Change option to 2" />

And, of course, the Event constructor is not supported in IE. So you may need to polyfill with this:

function Event( event, params ) {
    params = params || { bubbles: false, cancelable: false, detail: undefined };
    var evt = document.createEvent( 'CustomEvent' );
    evt.initCustomEvent( event, params.bubbles, params.cancelable, params.detail );
    return evt;
}

 (you have cv::Mat old)
 IplImage copy = old;
 IplImage* new_image = ©

you work with new as an originally declared IplImage*.

A simple one would be

\d{4}-\d{2}-\d{2}

Debuggex Demo

but this does not restrict month to 1-12 and days from 1 to 31.

There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.

In their simplest form, reset resets the index without touching the working tree, while checkout changes the working tree without touching the index.

Resets the index to match HEAD, working tree left alone:

git reset

Conceptually, this checks out the index into the working tree. To get it to actually do anything you would have to use -f to force it to overwrite any local changes. This is a safety feature to make sure that the "no argument" form isn't destructive:

git checkout

Once you start adding parameters it is true that there is some overlap.

checkout is usually used with a branch, tag or commit. In this case it will reset HEAD and the index to the given commit as well as performing the checkout of the index into the working tree.

Also, if you supply --hard to reset you can ask reset to overwrite the working tree as well as resetting the index.

If you current have a branch checked out out there is a crucial different between reset and checkout when you supply an alternative branch or commit. reset will change the current branch to point at the selected commit whereas checkout will leave the current branch alone but will checkout the supplied branch or commit instead.

Other forms of reset and commit involve supplying paths.

If you supply paths to reset you cannot supply --hard and reset will only change the index version of the supplied paths to the version in the supplied commit (or HEAD if you don't specify a commit).

If you supply paths to checkout, like reset it will update the index version of the supplied paths to match the supplied commit (or HEAD) but it will always checkout the index version of the supplied paths into the working tree.

This can be addressed simple by CSS attribute:

XML: <label name="pageTac"> Hello how are you doing? Thank you I'm Good</label>

CSS

.pageText{
white-space:pre !important; // this wraps the xml text.}

HTML / XSL

<tr>
        <td class="pageText"><xsl:value-of select="$Dictionary/infolabels/label[@name='pageTac']" />
            </td></tr>

Simply you can add that way. see below the console image

Based on the answer that @Mukund Kumar gave here's a version that passes the event argument to the anonymous function:

<a href="#" onClick="(function(e){
    console.log(e);
    alert('Hey i am calling');
    return false;
})(arguments[0]);return false;">click here</a>

One-liner in Rebol:

rebol -q --do 's: 0 while [d: input] [s: s + to-integer d] print s' < infile.txt

Unfortunately the above doesn't work in Rebol 3 just yet (INPUT doesn't stream STDIN).

So here's an interim solution which also works in Rebol 3:

rebol -q --do 's: 0 foreach n to-block read %infile.txt [s: s + n] print s'

Set texts with different sizes and styles, and size and style for texts from cells ( with Range)

Sub EmailManuellAbsenden()

With ghApp.CreateItem(0)
.To = Range("B2")
.CC = Range("B3")
.Subject = Range("B4")
.GetInspector.Display
 ghOldBody = .htmlBody

 ghNewBody = "<font style=""font-family: Calibri; font-size: 11pt;""/font>" & _
 "<font style=""font-family: Arial; font-size: 14pt;"">Arial Text 14</font>" & _

 .htmlBody = ghNewBody & ghOldBody

 End With

End Sub
'Fill B2 to B6 with some letters for testing
'"<font style=""font-family: Calibri; font-size: 15pt;""/font>" = works for all Range Objekts

Yes, it is possible.

try:

See: http://docs.python.org/tutorial/errors.html

The "as" keyword is used to assign the error to a variable so that the error can be investigated more thoroughly later on in the code. Also note that the parentheses for the triple exception case are needed in python 3. This page has more info: Catch multiple exceptions in one line (except block)

Thanks for your answers. I didn't understand what type of object "MyTable" was (in your answers) and the following code gave me the error shown below.

DataTable dt = ds.Tables[0];
var name = from r in dt
           where r.ID == 0
           select r.Name;

Could not find an implementation of the query pattern for source type 'System.Data.DataTable'. 'Where' not found

So I continued my googling and found something that does work:

var rowColl = ds.Tables[0].AsEnumerable();
string name = (from r in rowColl
              where r.Field<int>("ID") == 0
              select r.Field<string>("NAME")).First<string>();

What do you think?

IMO it's the different way to resolve a name from the OS and PHP.

Try:

echo gethostbyname("host.name.tld");

and

var_export (dns_get_record ( "host.name.tld") );

or

$dns=array("8.8.8.8","8.8.4.4");
var_export (dns_get_record ( "host.name.tld" ,  DNS_ALL , $dns ));

You should found some DNS/resolver error.

The patch is here: https://code.ros.org/trac/opencv/attachment/ticket/862/OpenCV-2.2-nov4l1.patch

By adding #ifdef HAVE_CAMV4L around

#include <linux/videodev.h>

in OpenCV-2.2.0/modules/highgui/src/cap_v4l.cpp and removing || defined (HAVE_CAMV4L2) from line 174 allowed me to compile.

I use thisone, it's only Javascript.

I simply have an input element with a value, and when the user clicks on the input element, it changes it to an input element without a value.

You can easily change the color of the text using CSS. The color of the placeholder is the color in the id #IEinput, and the color your typed text will be is the color in the id #email. Don't use getElementsByClassName, because the versions of IE that don't support a placeholder, don't support getElementsByClassName either!

You can use a placeholder in a password input by setting the type of the original password input to text.

For those who have a custom jQuery UI build (bower for ex.), add the effects core located in ..\jquery-ui\ui\effect.js.

This is a gem:

https://www.digitalocean.com/community/tutorials/an-introduction-to-oauth-2

Very brief summary:

OAuth defines four roles:

1. Resource Owner
2. Client
3. Resource Server
4. Authorization Server

You (Resource Owner) have a mobile phone. You have several different email accounts, but you want all your email accounts in one app, so you don't need to keep switching. So your GMail (Client) asks for access (via Yahoo's Authorization Server) to your Yahoo emails (Resource Server) so you can read both emails on your GMail application.

The reason OAuth exists is because it is unsecure for GMail to store your Yahoo username and password.

I'm sure this might be useful for someone out there. In my case I am running Android Studio in a mac and also trying Visual Studio Xamarin. Having both of them opened at the same time was creating this conflict. So closing Visual was enough.

With .Net 4.x you can use Task-based Asynchronous Pattern (TAP) to achieve this:

// .NET 4.x async-await
using UnityEngine;
using System.Threading.Tasks;
public class AsyncAwaitExample : MonoBehaviour
{
     private async void Start()
     {
        Debug.Log("Wait.");
        await WaitOneSecondAsync();
        DoMoreStuff(); // Will not execute until WaitOneSecond has completed
     }
    private async Task WaitOneSecondAsync()
    {
        await Task.Delay(TimeSpan.FromSeconds(1));
        Debug.Log("Finished waiting.");
    }
}

this is a feature to use .Net 4.x with Unity please see this link for description about it

and this link for sample project and compare it with coroutine

But becareful as documentation says that This is not fully replacement with coroutine

Quick answer for single line span

Make the child (in this case a span) the same line-height as the parent <div>'s height

<div class="parent">
  <span class="child">Yes mom, I did my homework lol</span>
</div>

You should then add the CSS rules

.parent { height: 20px; }
.child { line-height: 20px; vertical-align: middle; }

Or you can target it with a child selector

.parent { height: 20px; }
.parent > span { line-height: 20px; vertical-align: middle; }

Background on my own use of this

I ran into this similar issue where I needed to vertically center items in a mobile menu. I made the div and spans inside the same line height. Note that this is for a meteor project and therefore not using inline css ;)

HTML

<div class="international">        
  <span class="intlFlag">
    {{flag}}        
  </span>

  <span class="intlCurrent">
    {{country}}
  </span>

  <span class="intlButton">
    <i class="fa fa-globe"></i>
  </span> 
</div>

CSS (option for multiple spans in a div)

.international {
  height: 42px;
}

.international > span {
  line-height: 42px;
}

In this case if I just had one span I could have added the CSS rule directly to that span.

CSS (option for one specific span)

.intlFlag { line-height: 42px; }

Here is how it displayed for me

Like this:

xy.list <- split(xy.df, seq(nrow(xy.df)))

And if you want the rownames of xy.df to be the names of the output list, you can do:

xy.list <- setNames(split(xy.df, seq(nrow(xy.df))), rownames(xy.df))

You can also add the --cached flag to auco's answer to maintain local .DS_store files, as Edward Newell mentioned in his original answer. The modified command looks like this: find . -name .DS_Store -print0 | xargs -0 git rm --cached --ignore-unmatch ..cheers and thanks!

My solution is:

$maxs = array_keys($array, max($array))

Note:
this way you can retrieve every key related to a given max value.

If you are interested only in one key among all simply use $maxs[0]

In Netbeans you can right click on the project and run it, but in IntelliJ IDEA you have to select the index.jsp file or the welcome file to run the project.

this is because Netbeans generate the following tag in web.xml and IntelliJ do not.

<welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
</welcome-file-list>

In my case, it was because of exception inside the constructor of my injected dependency (in your example - inside DashboardRepository constructor). The exception was caught somewhere inside MVC infrastructure. I found this after I added logs in relevant places.

Do you mean design as in 'graphic representation of tables' or just plain old 'engineering kind of design'. If it's the latter, use FlameRobin, version 0.9.0 has just been released.

If it's the former, then use DBDesigner. Yup, that uses Java.

Or maybe you meant something more like MS Access. Then Kexi should be right for you.

If anyone is trying to get line-clamp to work in flexbox, it's slightly trickier - especially once you are torture testing with really long words. The only real differences in this code snippet are min-width: 0; in the flex item containing truncated text, and word-wrap: break-word;. A hat-tip to https://css-tricks.com/flexbox-truncated-text/ for the insight. Disclaimer: this is still webkit only as far as I know.

.flex-parent {
  display: flex;
}

.short-and-fixed {
  width: 30px;
  height: 30px;
  background: lightgreen;
}

.long-and-truncated {
  margin: 0 20px;
  flex: 1;
  min-width: 0;/* Important for long words! */
}

.long-and-truncated span {
  display: inline;
  -webkit-line-clamp: 3;
  text-overflow: ellipsis;
  overflow: hidden;
  display: -webkit-box;
  -webkit-box-orient: vertical;
  word-wrap: break-word;/* Important for long words! */
}

I have had an issue using Bootstrap where using double quotes did matter vs using single quote (which didn't work). class='row-fluid' gave me issues causing the last span to fall below the other spans rather than sitting nicely beside on the far right, whereas class="row-fluid" worked.

getWeekOfYear: function(date) {
        var target = new Date(date.valueOf()),
            dayNumber = (date.getUTCDay() + 6) % 7,
            firstThursday;

        target.setUTCDate(target.getUTCDate() - dayNumber + 3);
        firstThursday = target.valueOf();
        target.setUTCMonth(0, 1);

        if (target.getUTCDay() !== 4) {
            target.setUTCMonth(0, 1 + ((4 - target.getUTCDay()) + 7) % 7);
        }

        return Math.ceil((firstThursday - target) /  (7 * 24 * 3600 * 1000)) + 1;
    }

Following code is timezone-independent (UTC dates used) and works according to the https://en.wikipedia.org/wiki/ISO_8601

You can't update with a number greater than 1 for datatype number(2,2) is because, the first parameter is the total number of digits in the number and the second one (.i.e 2 here) is the number of digits in decimal part. I guess you can insert or update data < 1. i.e. 0.12, 0.95 etc.

Please check NUMBER DATATYPE in NUMBER Datatype.

This code will print a pyramid of dollars.

As Tim Potter pointed out, setting proxy in dockerfile is horrible. When building the image, you add proxy for your corporate network but you may be deploying in cloud or a DMZ where there is no need for proxy or the proxy server is different.

Also, you cannot share your image with others outside your corporate n/w.

The port number is an unsigned 16-bit integer, so 65535.

It's more convenient to use a session, this way you don't have to remember to set headers each time:

session = requests.Session()
session.headers.update({'User-Agent': 'Custom user agent'})

session.get('https://httpbin.org/headers')

By default, session also manages cookies for you. In case you want to disable that, see this question.

I met some problems in Clion and finally, I solved them. Here is some experience.

1. Download and install MinGW
2. g++ and gcc package should be installed by default. Use the MinGW installation manager to install mingw32-libz and mingw32-make. You can open MinGW installation manager through C:\MinGW\libexec\mingw-get.exe This step is the most important step. If Clion cannot find make, C compiler and C++ compiler, recheck the MinGW installation manager to make every necessary package is installed.
3. In Clion, open File->Settings->Build,Execution,Deployment->Toolchains. Set MinGW home as your local MinGW file.
4. Start your "Hello World"!

It depends..

SELECT x.col
FROM big_table x
WHERE x.key IN( SELECT key FROM really_big_table );

would not be relatively slow the isn't much to limit size of what the query check to see if they key is in. EXISTS would be preferable in this case.

But, depending on the DBMS's optimizer, this could be no different.

As an example of when EXISTS is better

SELECT x.col
FROM big_table x
WHERE EXISTS( SELECT key FROM really_big_table WHERE key = x.key);
  AND id = very_limiting_criteria

mapStateToProps receives the state and props and allows you to extract props from the state to pass to the component.

mapDispatchToProps receives dispatch and props and is meant for you to bind action creators to dispatch so when you execute the resulting function the action gets dispatched.

I find this only saves you from having to do dispatch(actionCreator()) within your component thus making it a bit easier to read.

Avoiding the 5GHz WiFi in the client seems to have fixed the issue. That's what worked for me (server was always connected to 2.4GHz).

There's absolutely nothing wrong with including the entirety of jQuery within your Greasemonkey script. Just take the source, and place it at the top of your user script. No need to make a script tag, since you're already executing JavaScript!

The user only downloads the script once anyways, so size of script is not a big concern. In addition, if you ever want your Greasemonkey script to work in non-GM environments (such as Opera's GM-esque user scripts, or Greasekit on Safari), it'll help not to use GM-unique constructs such as @require.

If the database are in the same server use [DatabaseName].[Owner].[TableName] format when accessing a table that resides in a different database.

Eg: [DB1].[dbo].[TableName]

If databases in different server look at on Creating Linked Servers (SQL Server Database Engine)

For those of you who need to convert hexadecimal representation of a signed byte from two-character String into byte (which in Java is always signed), there is an example. Parsing a hexadecimal string never gives negative number, which is faulty, because 0xFF is -1 from some point of view (two's complement coding). The principle is to parse the incoming String as int, which is larger than byte, and then wrap around negative numbers. I'm showing only bytes, so that example is short enough.

String inputTwoCharHex="FE"; //whatever your microcontroller data is

int i=Integer.parseInt(inputTwoCharHex,16);
//negative numbers is i now look like 128...255

// shortly i>=128
if (i>=Integer.parseInt("80",16)){

    //need to wrap-around negative numbers
    //we know that FF is 255 which is -1
    //and FE is 254 which is -2 and so on
    i=-1-Integer.parseInt("FF",16)+i;
    //shortly i=-256+i;
}
byte b=(byte)i;
//b is now surely between -128 and +127

This can be edited to process longer numbers. Just add more FF's or 00's respectively. For parsing 8 hex-character signed integers, you need to use Long.parseLong, because FFFF-FFFF, which is integer -1, wouldn't fit into Integer when represented as a positive number (gives 4294967295). So you need Long to store it. After conversion to negative number and casting back to Integer, it will fit. There is no 8 character hex string, that wouldn't fit integer in the end.

Yes. For that ensure that you declare the worksheet

For example

Previous Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet3")

    Debug.Print ws.Cells(23, 4).Value
End Sub

New Code

Sub Sample()
    Dim ws As Worksheet

    Set ws = Sheets("Sheet4")

    Debug.Print ws.Cells(23, 4).Value
End Sub

Did you install the drivers? See the Arduino installation instructions under #4. I don't know that machine but I doubt it doesn't have any COM ports.

This is hard for to do on MAC seeing as it doesn't have access to the windows functions that can help clear the screen. My best fix is to loop and add lines until the terminal is clear and then run the program. However this isn't as efficient or memory friendly if you use this primarily and often.

void clearScreen(){
    int clear = 5;
    do {
        cout << endl;
        clear -= 1;
    } while (clear !=0);
}

== is a bash-specific alias for = and it performs a string (lexical) comparison instead of a numeric comparison. eq being a numeric comparison of course.

Finally, I usually prefer to use the form if [ "$a" == "$b" ]

All the answers worked. However, I had to add the variables that I needed to get to the sudoers files as follows:

sudo visudo
Defaults env_keep += "<var1>, <var2>, ..., <varn>"

Thought I'd share this code snippet that I've used before, this adds multiple addresses via Geocode and adds these addresses as Markers...

var addressesArray = [_x000D_
  'Address Str.No, Postal Area/city',_x000D_
  //follow this structure_x000D_
]_x000D_
var map = new google.maps.Map(document.getElementById('map'), {_x000D_
  center: {_x000D_
    lat: 12.7826,_x000D_
    lng: 105.0282_x000D_
  },_x000D_
  zoom: 6,_x000D_
  gestureHandling: 'cooperative'_x000D_
});_x000D_
var geocoder = new google.maps.Geocoder();_x000D_
for (i = 0; i < addressArray.length; i++) {_x000D_
  var address = addressArray[i];_x000D_
  geocoder.geocode({_x000D_
    'address': address_x000D_
  }, function(results, status) {_x000D_
    if (status === 'OK') {_x000D_
      var marker = new google.maps.Marker({_x000D_
        map: map,_x000D_
        position: results[0].geometry.location,_x000D_
        center: {_x000D_
          lat: 12.7826,_x000D_
          lng: 105.0282_x000D_
        },_x000D_
      });_x000D_
    } else {_x000D_
      alert('Geocode was not successful for the following reason: ' + status);_x000D_
    }_x000D_
  });_x000D_
}

Use an XDocument to create the DOM, then write it out using an XmlWriter. This will give you a wonderfully concise and readable notation as well as nicely formatted output.

Take this sample program:

using System.Xml;
using System.Xml.Linq;

class Program {
    static void Main() {
        var xDocument = new XDocument(
            new XDocumentType("html", null, null, null),
            new XElement("html",
                new XElement("head"),
                new XElement("body",
                    new XElement("p",
                        "This paragraph contains ", new XElement("b", "bold"), " text."
                    ),
                    new XElement("p",
                        "This paragraph has just plain text."
                    )
                )
            )
        );

        var settings = new XmlWriterSettings {
            OmitXmlDeclaration = true, Indent = true, IndentChars = "\t"
        };
        using (var writer = XmlWriter.Create(@"C:\Users\wolf\Desktop\test.html", settings)) {
            xDocument.WriteTo(writer);
        }
    }
}

This generates the following output:

<!DOCTYPE html >
<html>
    <head />
    <body>
        <p>This paragraph contains <b>bold</b> text.</p>
        <p>This paragraph has just plain text.</p>
    </body>
</html>

std::stringstream::str() is the method you are looking for.

With std::stringstream:

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::stringstream ss;
    ss << NumericValue;
    return ss.str();
}

std::stringstream is a more generic tool. You can use the more specialized class std::ostringstream for this specific job.

template <class T>
std::string YourClass::NumericToString(const T & NumericValue)
{
    std::ostringstream oss;
    oss << NumericValue;
    return oss.str();
}

If you are working with std::wstring type of strings, you must prefer std::wstringstream or std::wostringstream instead.

template <class T>
std::wstring YourClass::NumericToString(const T & NumericValue)
{
    std::wostringstream woss;
    woss << NumericValue;
    return woss.str();
}

if you want the character type of your string could be run-time selectable, you should also make it a template variable.

template <class CharType, class NumType>
std::basic_string<CharType> YourClass::NumericToString(const NumType & NumericValue)
{
    std::basic_ostringstream<CharType> oss;
    oss << NumericValue;
    return oss.str();
}

For all the methods above, you must include the following two header files.

#include <string>
#include <sstream>

Note that, the argument NumericValue in the examples above can also be passed as std::string or std::wstring to be used with the std::ostringstream and std::wostringstream instances respectively. It is not necessary for the NumericValue to be a numeric value.

Did you edit the AndroidManifest.xml directly in the .apk file? If so, that won't work.

Every Android .apk needs to be signed if it is going to be installed on a phone, even if you're not installing through the Market. The development tools work round this by signing with a development certificate but the .apk is still signed.

One use of this is so a device can tell if an .apk is a valid upgrade for an installed application, since if it is the Certificates will be the same.

So if you make any changes to your app at all you'll need to rebuild the .apk so it gets signed properly.

You could detect position of the mouse pointer and then move the web page (with body position relative) so they hover over what you want them to click.

For an example you can paste this code on the current page in your browser console (and refresh afterwards)

var upvote_position = $('#answer-12878316').position();
$('body').mousemove(function (event) {
    $(this).css({
        position: 'relative',
        left: (event.pageX - upvote_position.left - 22) + 'px',
        top: (event.pageY - upvote_position.top - 35) + 'px'
    });        
});

Remember that when you restart the database by removing .lock files by force, the data might get corrupted. Your server shouldn't be considered "healthy" if you restarted the server that way.

To amend the situation, either run

mongod --repair

or

> db.repairDatabase();    

in the mongo shell to bring your database back to "healthy" state.

I recommend php-ffmpeg library.

Extracting image

You can extract a frame at any timecode using the FFMpeg\Media\Video::frame method.

This code returns a FFMpeg\Media\Frame instance corresponding to the second 42. You can pass any FFMpeg\Coordinate\TimeCode as argument, see dedicated documentation below for more information.

$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(42));
$frame->save('image.jpg');

If you want to extract multiple images from the video, you can use the following filter:

$video
    ->filters()
    ->extractMultipleFrames(FFMpeg\Filters\Video\ExtractMultipleFramesFilter::FRAMERATE_EVERY_10SEC, '/path/to/destination/folder/')
    ->synchronize();

$video
    ->save(new FFMpeg\Format\Video\X264(), '/path/to/new/file');

By default, this will save the frames as jpg images.

You are able to override this using setFrameFileType to save the frames in another format:

$frameFileType = 'jpg'; // either 'jpg', 'jpeg' or 'png'
$filter = new ExtractMultipleFramesFilter($frameRate, $destinationFolder);
$filter->setFrameFileType($frameFileType);

$video->addFilter($filter);

Spring.Net is quite solid, but the documentation took some time to wade through. Autofac is good, and while .Net 2.0 is supported, you need VS 2008 to compile it, or else use the command line to build your app.

it is a collection which is used to notify mostly UI to change in the collection , it supports automatic notification.

Mainly used in WPF ,

Where say suppose you have UI with a list box and add button and when you click on he button an object of type suppose person will be added to the obseravablecollection and you bind this collection to the ItemSource of Listbox , so as soon as you added a new item in the collection , Listbox will update itself and add one more item in it.

I had the same error and google brought me to this question, so here is what I did, hoping that it helps others in a similar situation.

This is applicable for OS X.

Check in the Terminal which version of OpenSSL I had:

$ python3 -c "import ssl; print(ssl.OPENSSL_VERSION)"
>> OpenSSL 0.9.8zh 14 Jan 2016

As my version of OpenSSL was too old, the accepted answer did not work.

So I had to update OpenSSL. To do this, I updated Python to the latest version (from version 3.5 to version 3.6) with Homebrew, following some of the steps suggested here:

$ brew update
$ brew install openssl
$ brew install python3

Then I was having problems with the PATH and the version of python being used, so I just created a new virtualenv making sure that the newest version of python was taken:

$ virtualenv webapp --python=python3.6

Issue solved.

As requested, I decided to extend my comment on forefinger's answer to a full-fledged answer. Although his answer is correct, it is needlessly complex. Furthermore all current answers use signed ints to represent the values. This is dangerous, as right-shifting of negative values is implementation-defined (i.e. not portable) and left-shifting can lead to undefined behavior (see this question).

By right-shifting the desired bit into the least significant bit position, masking can be done with 1. No need to compute a new mask value for each bit.

(n >> k) & 1

As a complete program, computing (and subsequently printing) an array of single bit values:

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

int main(int argc, char** argv)
{
    unsigned
        input = 0b0111u,
        n_bits = 4u,
        *bits = (unsigned*)malloc(sizeof(unsigned) * n_bits),
        bit = 0;

    for(bit = 0; bit < n_bits; ++bit)
        bits[bit] = (input >> bit) & 1;

    for(bit = n_bits; bit--;)
        printf("%u", bits[bit]);
    printf("\n");

    free(bits);
}

Assuming that you want to calculate all bits as in this case, and not a specific one, the loop can be further changed to

for(bit = 0; bit < n_bits; ++bit, input >>= 1)
    bits[bit] = input & 1;

This modifies input in place and thereby allows the use of a constant width, single-bit shift, which may be more efficient on some architectures.

It happens because QuartzCore has the coordinate system "bottom-left", while UIKit – "top-left".

In the case you can extend CGContext:

extension CGContext {
  func changeToTopLeftCoordinateSystem() {
    translateBy(x: 0, y: boundingBoxOfClipPath.size.height)
    scaleBy(x: 1, y: -1)
  }
}

// somewhere in render 
ctx.saveGState()
ctx.changeToTopLeftCoordinateSystem()
ctx.draw(cgImage!, in: frame)

Try to use:

location.reload(true);

When this method receives a true value as argument, it will cause the page to always be reloaded from the server. If it is false or not specified, the browser may reload the page from its cache.

If your int_field is indexed, remove the index before running the update. Then create your index again...

5 hours seem like a lot for 120 million recs.

Use iloc and select all rows (:) against the last column (-1):

df.iloc[:,-1:]

/proc/partitions will list all the block devices and partitions that the system recognizes. You can then try using file -s <device> to determine what kind of filesystem is present on the partition, if any.

It's not clear whether you're asking this because you are new to programming, but if that's the case then you should probably read this article on loops and indeed read some basic materials on programming.

If you already know about control structures and you want the R-specific implementation details then there are dozens of tutorials around, such as this one. The other answer uses replicate and colMeans, which is idiomatic when writing in R and probably blazing fast as well, which is important if you want 10,000 iterations.

However, one more general and (for beginners) straightforward way to approach problems of this sort would be to use a for loop.

> for (ii in 1:5) { + print(ii) + } [1] 1 [1] 2 [1] 3 [1] 4 [1] 5 > 

So in your case, if you just wanted to print the mean of your Tandem object 5 times:

for (ii in 1:5) {     Tandem <- sample(OUT, size = 815, replace = TRUE, prob = NULL)     TandemMean <- mean(Tandem)     print(TandemMean) } 

As mentioned above, replicate is a more natural way to deal with this specific problem using R. Either way, if you want to store the results - which is surely the case - you'll need to start thinking about data structures like vectors and lists. Once you store something you'll need to be able to access it to use it in future, so a little knowledge is vital.

set.seed(1234) OUT <- runif(100000, 1, 2) tandem <- list() for (ii in 1:10000) {     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) }  tandem[1] tandem[100] tandem[20:25] 

...creates this output:

> set.seed(1234) > OUT <- runif(100000, 1, 2) > tandem <- list() > for (ii in 1:10000) { +     tandem[[ii]] <- mean(sample(OUT, size = 815, replace = TRUE, prob = NULL)) + } >  > tandem[1] [[1]] [1] 1.511923  > tandem[100] [[1]] [1] 1.496777  > tandem[20:25] [[1]] [1] 1.500669  [[2]] [1] 1.487552  [[3]] [1] 1.503409  [[4]] [1] 1.501362  [[5]] [1] 1.499728  [[6]] [1] 1.492798  >  

Thanks to Erhun's answer I finally realised that my JSON mapper was returning the quotation marks around my data too! I needed to use "asText()" instead of "toString()"

It's not an uncommon issue - one's brain doesn't see anything wrong with the correct data, surrounded by quotes!

discoveryJson.path("some_endpoint").toString();
"https://what.the.com/heck"

discoveryJson.path("some_endpoint").asText();
https://what.the.com/heck

In addition to the dropDuplicates option there is the method named as we know it in pandas drop_duplicates:

drop_duplicates() is an alias for dropDuplicates().

Example

s_df = sqlContext.createDataFrame([("foo", 1),
                                   ("foo", 1),
                                   ("bar", 2),
                                   ("foo", 3)], ('k', 'v'))
s_df.show()

+---+---+
|  k|  v|
+---+---+
|foo|  1|
|foo|  1|
|bar|  2|
|foo|  3|
+---+---+

Drop by subset

s_df.drop_duplicates(subset = ['k']).show()

+---+---+
|  k|  v|
+---+---+
|bar|  2|
|foo|  1|
+---+---+
s_df.drop_duplicates().show()

Attempt http://challenge.greplin.com/ using Python

navigator.app.exitApp();

add this line where you want you exit the application.

To old files I don't know how to do it... I think you will need a script to go thru all files and add the header.

To change the new ones you can do this.

Go to Eclipse menu bar

1. Window menu.
2. Preferences
3. search for Templates
4. go to Code templates
5. click on +code
6. Click on New Java files
7. Click Edit
8. add

/**
${user}
*/

And it's done every new File will have your name on it !

I think I have an idea. This has been doing my nut in too and I'm still having trouble getting it to display in Chrome.

Save document(name.docx) in word as single file webpage (name.mht) In your html use

<iframe src= "name.mht" width="100%" height="800"> </iframe>

Alter the heights and widths as you see fit.

In the other hand, using REST API of other servers are very popular in PHP. Suppose you are looking for a way to redirect some HTTP requests into the other server (for example getting an xml file). Here is a PHP package to help you:

https://github.com/romanpitak/PHP-REST-Client

So, getting the xml file:

$client = new Client('http://example.com');
$request = $client->newRequest('/filename.xml');
$response = $request->getResponse();
echo $response->getParsedResponse();

In terms of comparing two numpy arrays and counting the number of matches (e.g. correct class prediction in machine learning), I found the below example for two dimensions useful:

import numpy as np
result = np.random.randint(3,size=(5,2)) # 5x2 random integer array
target = np.random.randint(3,size=(5,2)) # 5x2 random integer array

res = np.equal(result,target)
print result
print target
print np.sum(res[:,0])
print np.sum(res[:,1])

which can be extended to D dimensions.

The results are:

Prediction:

[[1 2]
 [2 0]
 [2 0]
 [1 2]
 [1 2]]

Target:

[[0 1]
 [1 0]
 [2 0]
 [0 0]
 [2 1]]

Count of correct prediction for D=1: 1

Count of correct prediction for D=2: 2

For those coming here from Google like I did, later versions of Powershell have a $foreach automatic variable. You can find the "current" object with $foreach.Current

to list the emulators you have

~/Library/Android/sdk/tools/emulator -list-avds

for example, I have this Nexus_5X_API_24

so the command to run that emulator is

cd ~/Library/Android/Sdk/tools && ./emulator -avd Nexus_5X_API_24

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

>>> from datetime import date
>>>
>>> repr(date.today())        # calls date.today().__repr__()
'datetime.date(2009, 1, 16)'
>>> eval(_)                   # _ is the output of the last command
datetime.date(2009, 1, 16)

The output is a string that can be parsed by the python interpreter and results in an equal object.

If that's not possible, it should return a string in the form of <...some useful description...>.

What I was looking for is a way to fetch the data

so I used this $data = $this->db->get('table_name')->result_array();

and then fetched my data just as you operate on array objects.

$data[0]['field_name']

No need to worry about type casting or anything just straight to the point.

So it worked for me.

String temp = "abcdefghi";
if(temp.indexOf("b")!=-1)
{
   System.out.println("there is 'b' in temp string");
}
else
{
   System.out.println("there is no 'b' in temp string");
}

Try using jQuery.parseJSON when you get the data back.

type: "POST",
dataType: "json",
url: url,
data: { get_member: id },
success: function(data) { 
    response = jQuery.parseJSON(data);
    $("input[ name = type ]:eq(" + response.type + " )")
        .attr("checked", "checked");
    $("input[ name = name ]").val( response.name);
    $("input[ name = fname ]").val( response.fname);
    $("input[ name = lname ]").val( response.lname);
    $("input[ name = email ]").val( response.email);
    $("input[ name = phone ]").val( response.phone);
    $("input[ name = website ]").val( response.website);
    $("#admin_member_img")
        .attr("src", "images/member_images/" + response.image);
},
error: function(error) {
    alert(error);
}

Unless you absolutely have to convert the date to an integer, consider using a Double instead to represent the time interval. After all, this is the type that timeIntervalSince1970 returns. All of the answers that convert to integers loose sub-millisecond precision, but this solution is much more accurate (although you will still lose some precision due to floating-point imprecision).

Don't need a regex. string[: string.find(' ')]

Reached the same problem, but instead of "hacking" or emulating command line:

from paramiko import SSHClient
from scp import SCPClient

ssh = SSHClient()
ssh.load_system_host_keys()
ssh.connect('example.com')

with SCPClient(ssh.get_transport()) as scp:
    scp.put('test.txt', 'test2.txt')
    scp.get('test2.txt')

You can use following css to make an element middle aligned styled with position: absolute:

.element {
  transform: translateX(-50%);
  position: absolute;
  left: 50%;
}

With CSS having only left: 50% we will have following effect:

While combining left: 50% with transform: translate(-50%) we will have following:

.hero {  _x000D_
  background-color: #e15915;_x000D_
  position: relative;_x000D_
  height: 320px;_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
_x000D_
.hero:after {_x000D_
  border-right: solid 50px transparent;_x000D_
  border-left: solid 50px transparent;_x000D_
  border-top: solid 50px #e15915;_x000D_
  transform: translateX(-50%);_x000D_
  position: absolute;_x000D_
  z-index: -1;_x000D_
  content: '';_x000D_
  top: 100%;_x000D_
  left: 50%;_x000D_
  height: 0;_x000D_
  width: 0;_x000D_
}

<div class="hero">_x000D_
_x000D_
</div>

I've gotten the same issue and one of the posted example in the manual worked. A character set must be specified as one of the posters here already mentioned. http://www.php.net/manual/en/function.ob-flush.php#109314

header( 'Content-type: text/html; charset=utf-8' );
echo 'Begin ...<br />';
for( $i = 0 ; $i < 10 ; $i++ )
{
    echo $i . '<br />';
    flush();
    ob_flush();
    sleep(1);
}
echo 'End ...<br />';

Check that on the "Runner" option is selected the correct device. Although you have one device physically plugged in with a cable, Xcode could have connected via WiFi to any other device that has the "Connect via network" option enabled.

Here is my approach to download JSON with plain node, no packages required.

import https from "https";

function get(url, resolve, reject) {
  https.get(url, (res) => {
    if(res.statusCode === 301 || res.statusCode === 302) {
      return get(res.headers.location, resolve, reject)
    }

    let body = [];

    res.on("data", (chunk) => {
      body.push(chunk);
    });

    res.on("end", () => {
      try {
        // remove JSON.parse(...) for plain data
        resolve(JSON.parse(Buffer.concat(body).toString()));
      } catch (err) {
        reject(err);
      }
    });
  });
}

async function getData(url) {
  return new Promise((resolve, reject) => get(url, resolve, reject));
}

// call
getData("some-url-with-redirect").then((r) => console.log(r));

This might be useful for someone else: Using this sample html

<div class="ParentDiv">
    <label for="label">labelName</label>
    <input type="button" value="elementToSelect">
</div>
<div class="DontSelect">
    <label for="animal">pig</label>
    <input type="button" value="elementToSelect">
</div>

If for example, I want to select an element in the same section (e.g div) as a label, you can use this

//label[contains(., 'labelName')]/parent::*//input[@value='elementToSelect'] 

This just means, look for a label (it could anything like a, h2) called labelName. Navigate to the parent of that label (i.e. div class="ParentDiv"). Search within the descendants of that parent to find any child element with the value of elementToSelect. With this, it will not select the second elementToSelect with DontSelect div as parent.

The trick is that you can reduce search areas for an element by navigating to the parent first and then searching descendant of that parent for the element you need. Other Syntax like following-sibling::h2 can also be used in some cases. This means the sibling following element h2. This will work for elements at the same level, having the same parent.

You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.

This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:

After trying to get this to work for too many hours, I finally found this: https://github.com/vierno/django-xhtml2pdf

It's a fork of https://github.com/chrisglass/django-xhtml2pdf that provides a mixin for a generic class-based view. I used it like this:

    # views.py
    from django_xhtml2pdf.views import PdfMixin
    class GroupPDFGenerate(PdfMixin, DetailView):
        model = PeerGroupSignIn
        template_name = 'groups/pdf.html'

    # templates/groups/pdf.html
    <html>
    <style>
    @page { your xhtml2pdf pisa PDF parameters }
    </style>
    </head>
    <body>
        <div id="header_content"> (this is defined in the style section)
            <h1>{{ peergroupsignin.this_group_title }}</h1>
            ...

Use the model name you defined in your view in all lowercase when populating the template fields. Because its a GCBV, you can just call it as '.as_view' in your urls.py:

    # urls.py (using url namespaces defined in the main urls.py file)
    url(
        regex=r"^(?P<pk>\d+)/generate_pdf/$",
        view=views.GroupPDFGenerate.as_view(),
        name="generate_pdf",
       ),

You can do this if you use an <a> tag instead of a button. I know it's not exactly what you asked for, but it might give you some other options if you cannot find a solution to this:

Borrowing from a demo from another answer here I produced this:

a {_x000D_
  display: block;_x000D_
  font-size: 18px;_x000D_
  border: 2px solid gray;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  text-align: center;_x000D_
  line-height: 100px;_x000D_
}_x000D_
_x000D_
a:active {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid green;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
a:target {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid red;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}

<a id="btn" href="#btn">Demo</a>

Notice the use of :target; this will be the style applied when the element is targeted via the hash. Which also means your HTML will need to be this: <a id="btn" href="#btn">Demo</a> a link targeting itself. and the demo http://jsfiddle.net/rlemon/Awdq5/4/

Thanks to @BenjaminGruenbaum here is a better demo: http://jsfiddle.net/agzVt/

_{Also, as a footnote: this should really be done with JavaScript and applying / removing CSS classes from the element. It would be much less convoluted.}

You can try this code:

cur.execute( "SELECT * FROM records WHERE email LIKE %s", (search,) )

You can see the documentation

import java.util.Arrays;

class Soft{
    public static void main(String[] args){
        int[] nums=range(9, 12);
        System.out.println(Arrays.toString(nums));
    }
    static int[] range(int low, int high){
        int[] a=new int[high-low];
        for(int i=0,j=low;i<high-low;i++,j++){
            a[i]=j;
        }
        return a;

    }
}

My code is similar to Python`s range :)

I fixed it by removing the top-level __init__.py in the parent folder of my sources.

To use offline Java API Documentation in Eclipse, you need to download it first. The link for Java docs are (last updated on 2013-10-21):

Java 6
Page: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u25-doc-download-355137.html
Direct: http://download.oracle.com/otn-pub/java/jdk/6u30-b12/jdk-6u30-apidocs.zip

Java 7

Java 9

1. Extract the zip file in your local directory.
2. From eclipse Window --> Preferences --> Java --> "Installed JREs" select available JRE (jre6: C:\Program Files (x86)\Java\jre6 for instance) and click Edit.
3. Select all the "JRE System libraries" using Control+A.
4. Click "Javadoc Location"
5. Change "Javadoc location path:" from "http://download.oracle.com/javase/6/docs/api/" to "file:/E:/Java/docs/api/".

It must work as it works for me. I don't need Internet connection to view Java API Documentation in Eclipse anymore.

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

The fast way to get the content of a directory using Java 7 NIO :

import java.nio.file.DirectoryStream;
import java.nio.file.Files;
import java.nio.file.FileSystems;
import java.nio.file.Path;

...

Path dir = FileSystems.getDefault().getPath( filePath );
DirectoryStream<Path> stream = Files.newDirectoryStream( dir );
for (Path path : stream) {
   System.out.println( path.getFileName() );
}
stream.close();

Try using while loop, Array.prototype.push()

var myArray = [], X = 3;
while (myArray.length < X) {
  myArray.push("")
}

Alternatively, using Array.prototype.fill()

var myArray = Array(3).fill("");

I catched the same error message today. The solution was to change the document from UTF-8 with BOM to UTF-8 without BOM

This is a MySQL-specific answer, not sure where else it works --

You can create an empty table having the same column definitions with:

CREATE TEMPORARY TABLE temp_foo LIKE foo;

And you can create a populated copy of an existing table with:

CREATE TEMPORARY TABLE temp_foo SELECT * FROM foo;

And the following works in postgres; unfortunately the different RDBMS's don't seem very consistent here:

CREATE TEMPORARY TABLE temp_foo AS SELECT * FROM foo;

Putting it in the "web.config" works fine. The problem was that I got the MIME type wrong. Instead of font/x-woff or font/x-font-woff it must be application/font-woff:

<system.webServer>
  ...
  <staticContent>
    <remove fileExtension=".woff" />
    <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
  </staticContent>
</system.webServer>

See also this answer regarding the MIME type: https://stackoverflow.com/a/5142316/135441

Update 4/10/2013

Spec is now a recommendation and the MIME type is officially: application/font-woff

Use ssh for that purpose. Generate keys without using a password and place it to .authorized_keys at the remote machine. Create the script to be run remotely, copy it to the other machine and then just run it remotely using ssh.

I used this approach many times with a big success. Also note that it is much more secure than telnet.

<mvc:annotation-driven /> means that you can define spring beans dependencies without actually having to specify a bunch of elements in XML or implement an interface or extend a base class. For example @Repository to tell spring that a class is a Dao without having to extend JpaDaoSupport or some other subclass of DaoSupport. Similarly @Controller tells spring that the class specified contains methods that will handle Http requests without you having to implement the Controller interface or extend a subclass that implements the controller.

When spring starts up it reads its XML configuration file and looks for <bean elements within it if it sees something like <bean class="com.example.Foo" /> and Foo was marked up with @Controller it knows that the class is a controller and treats it as such. By default, Spring assumes that all the classes it should manage are explicitly defined in the beans.XML file.

Component scanning with <context:component-scan base-package="com.mycompany.maventestwebapp" /> is telling spring that it should search the classpath for all the classes under com.mycompany.maventestweapp and look at each class to see if it has a @Controller, or @Repository, or @Service, or @Component and if it does then Spring will register the class with the bean factory as if you had typed <bean class="..." /> in the XML configuration files.

In a typical spring MVC app you will find that there are two spring configuration files, a file that configures the application context usually started with the Spring context listener.

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

And a Spring MVC configuration file usually started with the Spring dispatcher servlet. For example.

<servlet>
        <servlet-name>main</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>main</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

Spring has support for hierarchical bean factories, so in the case of the Spring MVC, the dispatcher servlet context is a child of the main application context. If the servlet context was asked for a bean called "abc" it will look in the servlet context first, if it does not find it there it will look in the parent context, which is the application context.

Common beans such as data sources, JPA configuration, business services are defined in the application context while MVC specific configuration goes not the configuration file associated with the servlet.

Hope this helps.

Use below syntax to create schema class from XSD file.

In CSS 2.1, the effect of 'min-height' and 'max-height' on tables, inline tables, table cells, table rows, and row groups is undefined.

So try wrapping the content in a div, and give the div a min-height jsFiddle here

<table cellspacing="0" cellpadding="0" border="0" style="width:300px">
    <tbody>
        <tr>
            <td>
                <div style="min-height: 100px; background-color: #ccc">
                    Hello World !
                </div>
            </td>
            <td>
                <div style="min-height: 100px; background-color: #f00">
                    Good Morning !
                </div>
            </td>

First go to the Directory : vendor/plugins/open_flash_chart_2 and DELETE

THEN :

git rm --cached vendor/plugins/open_flash_chart_2  
git add .  
git commit -m "Message"  
git push -u origin master  

git status  

OUTPUT

On branch master
Your branch is up-to-date with 'origin/master'.
nothing to commit, working directory clean

This is probably the closest translation from your C code to Python code.

A = 1
B = "hello"
buf = "A = %d\n , B= %s\n" % (A, B)

c = 2
buf += "C=%d\n" % c

f = open('output.txt', 'w')
print >> f, c
f.close()

The % operator in Python does almost exactly the same thing as C's sprintf. You can also print the string to a file directly. If there are lots of these string formatted stringlets involved, it might be wise to use a StringIO object to speed up processing time.

So instead of doing +=, do this:

import cStringIO
buf = cStringIO.StringIO()

...

print >> buf, "A = %d\n , B= %s\n" % (A, B)

...

print >> buf, "C=%d\n" % c

...

print >> f, buf.getvalue()

Run in background and add logs to log file using the following:

nohup java -jar /web/server.jar > log.log 2>&1 &

Easiest solution

<button type="button" onclick="window.location.href='{{ url_for( 'move_forward') }}';">Forward</button>

Use the method "toArray()"

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
Object[] mStringArray = mStringList.toArray();

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

or you can do it like this: (mentioned in other answers)

ArrayList<String>  mStringList= new ArrayList<String>();
mStringList.add("ann");
mStringList.add("john");
String[] mStringArray = new String[mStringList.size()];
mStringArray = mStringList.toArray(mStringArray);

for(int i = 0; i < mStringArray.length ; i++){
    Log.d("string is",(String)mStringArray[i]);
}

The simplest way would be to inject the following object where you need to initiate the shutdown

ShutdownManager.java

import org.springframework.context.ApplicationContext;
import org.springframework.boot.SpringApplication;

@Component
class ShutdownManager {

    @Autowired
    private ApplicationContext appContext;

    /*
     * Invoke with `0` to indicate no error or different code to indicate
     * abnormal exit. es: shutdownManager.initiateShutdown(0);
     **/
    public void initiateShutdown(int returnCode){
        SpringApplication.exit(appContext, () -> returnCode);
    }
}

I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:

gcc -o exec main.o add.o

But my program is a C++ program. Using the g++ compiler solved my issue:

g++ -o exec main.o add.o

I was always under the impression that gcc could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.

0.1 second Google search:

BOOL DirectoryExists(const char* dirName) {
  DWORD attribs = ::GetFileAttributesA(dirName);
  if (attribs == INVALID_FILE_ATTRIBUTES) {
    return false;
  }
  return (attribs & FILE_ATTRIBUTE_DIRECTORY);
}

You must first convert the string to a string array, like this:

$recipients = "Marcel <[email protected]>,Marcelt <[email protected]>"
[string[]]$To = $recipients.Split(',')

Then use Send-MailMessage like this:

Send-MailMessage -From "[email protected]" -To $To -subject "New files" -body "$teloadmin" -BodyAsHtml -priority High -dno onSuccess, onFailure -smtpServer 192.168.170.61

You can convert your number to string and use list slicing like this:

int(str(number)[:2])

Output:

>>> number = 1520
>>> int(str(number)[:2])
15

Simple Solution:

import pandas as pd
df = pd.read_csv('file_name.csv', engine='python')

you can find the third most salary with this query:

SELECT min(salary) 
FROM tblEmployee 
WHERE salary IN (SELECT TOP(3) salary 
                 FROM tblEmployee 
                 ORDER BY salary DESC)

Top-Level await has moved to stage 3, so the answer to your question How can I use async/await at the top level? is to just add await the call to main() :

async function main() {
    var value = await Promise.resolve('Hey there');
    console.log('inside: ' + value);
    return value;
}

var text = await main();  
console.log('outside: ' + text)

Or just:

const text = await Promise.resolve('Hey there');
console.log('outside: ' + text)

RFC 2616, section 14.9.1:

Indicates that all or part of the response message is intended for a single user and MUST NOT be cached by a shared cache...A private (non-shared) cache MAY cache the response.

Browsers could use this information. Of course, the current "user" may mean many things: OS user, a browser user (e.g. Chrome's profiles), etc. It's not specified.

For me, a more concrete example of Cache-Control: private is that proxy servers (which typically have many users) won't cache it. It is meant for the end user, and no one else.

FYI, the RFC makes clear that this does not provide security. It is about showing the correct content, not securing content.

This usage of the word private only controls where the response may be cached, and cannot ensure the privacy of the message content.

Eclipse Collections has Pair and all combinations of primitive/object Pairs (for all eight primitives).

The Tuples factory can create instances of Pair, and the PrimitiveTuples factory can be used to create all combinations of primitive/object pairs.

We added these before Java 8 was released. They were useful to implement key/value Iterators for our primitive maps, which we also support in all primitive/object combinations.

If you're willing to add the extra library overhead, you can use Stuart's accepted solution and collect the results into a primitive IntList to avoid boxing. We added new methods in Eclipse Collections 9.0 to allow for Int/Long/Double collections to be created from Int/Long/Double Streams.

IntList list = IntLists.mutable.withAll(intStream);

Note: I am a committer for Eclipse Collections.

you can do like follows. Remember, IsNull is a function which returns TRUE if the parameter passed to it is null, and false otherwise.

Not IsNull(Fields!W_O_Count.Value)

You may follow the following steps:

• Open your CMD(Command Prompt)
• Type 'D:' and hit Enter. Example: C:\Users\[Your User Name]>D:
• Type 'CD VBS' and hit Enter. Example: D:>CD VBS
• Type 'Converter.vbs' or 'start Converter.vbs' and hit Enter. Example: D:\VBS>Converter.vbs Or D:\VBS>start Converter.vbs

You could use the IndexOf method to get a location of the string, and split it using that position, and the length of the search string.

You can also use regular expression. A simple google search turned out with this

using System;
using System.Text.RegularExpressions;

class Program {
  static void Main() {
    string value = "cat\r\ndog\r\nanimal\r\nperson";
    // Split the string on line breaks.
    // ... The return value from Split is a string[] array.
    string[] lines = Regex.Split(value, "\r\n");

    foreach (string line in lines) {
        Console.WriteLine(line);
    }
  }
}

This will also work:

import os 
import boto
import boto.s3.connection
from boto.s3.key import Key

try:

    conn = boto.s3.connect_to_region('us-east-1',
    aws_access_key_id = 'AWS-Access-Key',
    aws_secret_access_key = 'AWS-Secrete-Key',

Maybe you are looking for something like this:

StackFrame frame = new StackFrame(1);
frame.GetMethod().Name; //Gets the current method name

MethodBase method = frame.GetMethod();
method.DeclaringType.Name //Gets the current class name

Search environment variables.

open the "edit the system environment variables". then click on "environment variables".

Under "User variables" click on "Path" then "Edit".

Find your Java path and click "Edit".

then paste the path of your java installation folder. Mostly you can find it on a path similar to this. C:\Program Files\Java\jdk-12.0.2\bin

Then click OK. now in the start menu, type cmd. open the command prompt. type java -version If you did it right,it should show something like this.

Use registers in commands with @. E.g.:

echo @a
echo @0
echo @+

Set them in command:

let @a = 'abc'

Now "ap will paste abc.

You can use the ?? test operator:

This checks if the attribute of the object is not null:

<#if object.attribute??></#if>

This checks if object or attribute is not null:

<#if (object.attribute)??></#if>

Source: FreeMarker Manual

you have to use self as the first parameters of a method

in the second case you should use

class MathOperations:
    def testAddition (self,x, y):
        return x + y

    def testMultiplication (self,a, b):
        return a * b

and in your code you could do the following

tmp = MathOperations
print tmp.testAddition(2,3)

if you use the class without instantiating a variable first

print MathOperation.testAddtion(2,3)

it gives you an error "TypeError: unbound method"

if you want to do that you will need the @staticmethod decorator

For example:

class MathsOperations:
    @staticmethod
    def testAddition (x, y):
        return x + y

    @staticmethod
    def testMultiplication (a, b):
        return a * b

then in your code you could use

print MathsOperations.testAddition(2,3)

sudo perl -MCPAN -e 'install Foo'

HTML:

<button type="submit" name="submit" class="button">
  <img src="images/free.png" />
</button>

Local variables aren't initialized. You have to manually initialize them.

Members are initialized, for example:

public class X
{
    private int _tmpCnt; // This WILL initialize to zero
    ...
}

But local variables are not:

public static void SomeMethod()
{
    int tmpCnt;  // This is not initialized and must be assigned before used.

    ...
}

So your code must be:

int tmpCnt = 0;  
if (name == "Dude")  
   tmpCnt++;  

So the long and the short of it is, members are initialized, locals are not. That is why you get the compiler error.

You will get this under the project setting

This is an old topic, but in case anyone else is still looking...

I was having trouble after an undock event. An open db connection saved in a global object would error, even after reconnecting to the network. This was due to the TCP connection being forcibly terminated by remote host. (Error -2147467259: TCP Provider: An existing connection was forcibly closed by the remote host.)

However, the error would only show up after the first transaction was attempted. Up to that point, neither Connection.State nor Connection.Version (per solutions above) would reveal any error.

So I wrote the small sub below to force the error - hope it's useful.

Performance testing on my setup (Access 2016, SQL Svr 2008R2) was approx 0.5ms per call.

So I mashed all their ideas together and came up with this. This is the drag and drop solution to exactly what the first post asked.

It will automatically update the versionCode and versionName according to release status. Of course you can move the variables around to suite your needs.

def _versionCode=0
def versionPropsFile = file('version.properties')
def Properties versionProps = new Properties()
if(versionPropsFile.exists())
    versionProps.load(new FileInputStream(versionPropsFile))
    def _patch = (versionProps['PATCH'] ?: "0").toInteger() + 1
    def _major = (versionProps['MAJOR'] ?: "0").toInteger()
    def _minor = (versionProps['MINOR'] ?: "0").toInteger()
    List<String> runTasks = gradle.startParameter.getTaskNames();
    def value = 0
    for (String item : runTasks)
        if ( item.contains("assembleRelease")) {
            value = 1;
        }
    _versionCode = (versionProps['VERSION_CODE'] ?: "0").toInteger() + value
    if(_patch==99)
    {
        _patch=0
        _minor=_minor+1
    }
    if(_major==99){
        _major=0
        _major=_major+1
    }

versionProps['MAJOR']=_major.toString()
versionProps['MINOR']=_minor.toString()
versionProps['PATCH']=_patch.toString()
versionProps['VERSION_CODE']=_versionCode.toString()
versionProps.store(versionPropsFile.newWriter(), null)
def _versionName = "${_major}.${_versionCode}.${_minor}.${_patch}"

A 2 column layout is a little bit tough to get working in CSS (at least until CSS3 is practical.)

Floating left and right will work to a point, but it won't allow you to extend the background. To make backgrounds stay solid, you'll have to implement a technique known as "faux columns," which basically means your columns themselves won't have a background image. Your 2 columns will be contained inside of a parent tag. This parent tag is given a background image that contains the 2 column colors you want. Make this background only as big as you need it to (if it is a solid color, only make it 1 pixel high) and have it repeat-y. AListApart has a great walkthrough on what is needed to make it work.

I did the following:

void BrowserDocumentCompleted(object sender,
        WebBrowserDocumentCompletedEventArgs e)
{
  if (e.Url.AbsolutePath != (sender as WebBrowser).Url.AbsolutePath)
    return; 

  //The page is finished loading 
}

The last page loaded tends to be the one navigated to, so this should work.

From here.

You can add the following in your .bashrc

if [ "$TERM" = xterm ]; then TERM=xterm-256color; fi

They can be different on word-addressable machines (e.g., Cray PVP systems).

Most computers today are byte-addressable machines, where each address refers to a byte of memory. There, all data pointers are usually the same size, namely the size of a machine address.

On word-adressable machines, each machine address refers instead to a word larger than a byte. On these, a (char *) or (void *) pointer to a byte of memory has to contain both a word address plus a byte offset within the addresed word.

in reference to #Marcelo Lazaroni solution above

Date.now() + Math.random()

returns a number such as this 1567507511939.4558 (limited to 4 decimals), and will give non-unique numbers (or collisions) every 0.1%.

adding toString() fixes this

Date.now() + Math.random().toString()

returns '15675096840820.04510962122198503' (a string), and is further so 'slow' that you never get the 'same' millisecond, anyway.

Circular dependency in Spring : Dependency of one Bean to other. Bean A ? Bean B ? Bean A

Solutions:

1. Use @Lazy Annotation
2. Redesign you class dependency
3. Use Setter/Field Injection
4. Use @PostConstruct Annotation

No need to import any special libraries to do this.

Use normal syntax and it will open the file for reading then close it.

with open("/etc/hostname","r") as f: print f.read() 

or

with open("/etc/hosts","r") as f: x = f.read().splitlines()

which gives you an array x containing the lines, and can be printed like so:

for line in x: print line

These one-liners are very helpful for maintenance - basically self-documenting.

This should work:

DECLARE db_cursor CURSOR FOR SELECT name, age, color FROM table; 
DECLARE @myName VARCHAR(256);
DECLARE @myAge INT;
DECLARE @myFavoriteColor VARCHAR(40);
OPEN db_cursor;
FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
WHILE @@FETCH_STATUS = 0  
BEGIN  

       --Do stuff with scalar values

       FETCH NEXT FROM db_cursor INTO @myName, @myAge, @myFavoriteColor;
END;
CLOSE db_cursor;
DEALLOCATE db_cursor;

As Dumb Guy points out, it's important to note whether the array starts at zero and is sequential. Since you can make assignments to and unset non-contiguous indices ${#array[@]} is not always the next item at the end of the array.

$ array=(a b c d e f g h)
$ array[42]="i"
$ unset array[2]
$ unset array[3]
$ declare -p array     # dump the array so we can see what it contains
declare -a array='([0]="a" [1]="b" [4]="e" [5]="f" [6]="g" [7]="h" [42]="i")'
$ echo ${#array[@]}
7
$ echo ${array[${#array[@]}]}
h

Here's how to get the last index:

$ end=(${!array[@]})   # put all the indices in an array
$ end=${end[@]: -1}    # get the last one
$ echo $end
42

That illustrates how to get the last element of an array. You'll often see this:

$ echo ${array[${#array[@]} - 1]}
g

As you can see, because we're dealing with a sparse array, this isn't the last element. This works on both sparse and contiguous arrays, though:

$ echo ${array[@]: -1}
i

It's been more than 10 years and not sure if anyone still finding this question or answer relevant.

But a quick workaround is just to wrap the asp control within a html container

<div id="myElement" style="display: inline-block">
   <asp:TextBox ID="textBox1" runat="server"></asp:TextBox>
</div>

Whenever the Javascript Event is triggered, if it needs to be an event by the asp control, just wrap the asp control around the div container.

<div id="testG">  
   <asp:Button ID="Button2" runat="server" CssClass="btn" Text="Activate" />
</div>

The jQuery Code is below:

$(document).ready(function () {
    $("#testG").click(function () {
                $("#myElement").css("display", "none");
     });
});

The reason it is not working is because you are adding an item to the list and then overriding the whole list with a new DataSource which will clear and re-populate your list, losing the first manually added item.

So, you need to do this in reverse like this:

Status status = new Status();
DropDownList1.DataSource = status.getData();
DropDownList1.DataValueField = "ID";
DropDownList1.DataTextField = "Description";
DropDownList1.DataBind();

// Then add your first item
DropDownList1.Items.Insert(0, "Select");

An enum type is a special type of class.

Your enum will actually be compiled to something like

public final class MySingleton {
    public final static MySingleton INSTANCE = new MySingleton();
    private MySingleton(){} 
}

When your code first accesses INSTANCE, the class MySingleton will be loaded and initialized by the JVM. This process initializes the static field above once (lazily).

Until the end of 2014, a common source of this error was omitting the mandatory sensor parameter from the request, as below. However since then this is no longer required:

The sensor Parameter

The Google Maps API previously required that you include the sensor parameter to indicate whether your application used a sensor to determine the user's location. This parameter is no longer required.

Did you specify the sensor parameter on the request?

"REQUEST_DENIED" indicates that your request was denied, generally because of lack of a sensor parameter.

sensor (required) — Indicates whether or not the geocoding request comes from a device with a location sensor. This value must be either true or false

Considering background-images can't be animated, I created a little SCSS mixin allowing to transition between 2 different background-images using pseudo selectors before and after. They are at different z-index layers. The one that is ahead starts with opacity 0 and becomes visible with hover.

You can use it the same approach for creating animations with linear-gradients too.

scss

@mixin bkg-img-transition( $bkg1, $bkg2, $transTime:0.5s ){  
  position: relative;  
  z-index: 100; 
  &:before, &:after {
    background-size: cover;  
    content: '';    
    display: block;
    height: 100%;
    position: absolute;
    top: 0; left: 0;    
    width: 100%;    
    transition: opacity $transTime;
  }
  &:before {    
    z-index: -101;
    background-image: url("#{$bkg1}");    
  }
  &:after {    
    z-index: -100;
    opacity: 0;
    background-image: url("#{$bkg2}");    
  }
  &:hover {
     &:after{
       opacity: 1; 
     }
  }  
}

Now you can simply use it with

@include bkg-img-transition("https://picsum.photos/300/300/?random","https://picsum.photos/g/300/300");

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

What about:

const n = 123456;
Array.from(n.toString()).map(Number);
// [1, 2, 3, 4, 5, 6]

The provided solution here is correct. However, the same error can also occur from a user error, where your endpoint request method is NOT matching the method your using when making the request.

For example, the server endpoint is defined with "RequestMethod.PUT" while you are requesting the method as POST.

i had same issues , i was trying to mount C:\Users\ folder on docker

Vertical align only works in some select cases. The easiest way to make it function is to set display: table in the parent element's CSS and display: table-cell; to the child element and then apply your vertical align attribute.

first, store the last time the user made a request

<?php
  $_SESSION['timeout'] = time();
?>

in subsequent request, check how long ago they made their previous request (10 minutes in this example)

<?php
  if ($_SESSION['timeout'] + 10 * 60 < time()) {
     // session timed out
  } else {
     // session ok
  }
?>

There's, however, slight difference among all these options which

I found out that

If you do

    string URL = Server.MapPath("~");

or

    string URL = Server.MapPath("/");

or

    string URL = HttpRuntime.AppDomainAppPath;

your URL will display resources in your link like this:

    "file:///d:/InetPUB/HOME/Index/bin/Resources/HandlerDoc.htm"

But if you want your URL to show only virtual path not the resources location, you should do

    string URL = HttpRuntime.AppDomainAppVirtualPath; 

then, your URL is displaying a virtual path to your resources as below

    "http://HOME/Index/bin/Resources/HandlerDoc.htm"        

If you dont want to format a separate column with you normal dates pasted to it -- do the following -- add a column to the extreme left of your data and reverve your date ie if the date you had already entered was for example 11.5.16 enter int he new lefthand column 160511 ( notice that there are numbers only and no full stops . When you now sort there will be no mix ups as you have encountered.i have used this method for over 30 years and it never lets me down. And as you have placed the date by year, month and day you neednt include that column if you want or need tu print out your complete list.

If you wrap your <li> content in a <span> or other tag, you may change the font size of the <li>, which will change the size of the bullet, then reset the content of the <li> to its original size. You may use em units to resize the <li> bullet proportionally.

For example:

<ul>
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

Then CSS:

li {
    list-style-type: disc;
    font-size: 0.8em;
}

li * {
    font-size: initial;
}

A more complex example:

<!DOCTYPE html>
<html lang="en">
<head>
    <title>List Item Bullet Size</title>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <style>
ul.disc li {
    list-style-type: disc;
    font-size: 1.5em;
}

ul.square li {
    list-style-type: square;
    font-size: 0.8em;
}

li * {
    font-size: initial;
}
    </style>
</head>
<body>

<h1>First</h1>
<ul class="disc">
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

<h1>Second</h1>
<ul class="square">
    <li><span>First item</span></li>
    <li><span>Second item</span></li>
</ul>

</body>
</html>

Results in:

Try the below code snippet

<!doctype html>
<html>
  <head>
    <title>Audio</title>
  </head>
  <body>

    <script>
      function play() {
        var audio = document.getElementById("audio");
        audio.play();
      }
    </script>

    <input type="button" value="PLAY" onclick="play()">

The var keyword in C#'s main benefit is to enhance readability, not functionality. Technically, the var keywords allows for some other unlocks (e.g. use of anonymous objects), but that seems to be outside the scope of this question. Every variable declared with the var keyword has a type. For instance, you'll find that the following code outputs "String".

var myString = "";
Console.Write(myString.GetType().Name);

Furthermore, the code above is equivalent to:

String myString = "";
Console.Write(myString.GetType().Name);

The var keyword is simply C#'s way of saying "I can figure out the type for myString from the context, so don't worry about specifying the type."

var myVariable = (MyType)null or MyType myVariable = null should work because you are giving the C# compiler context to figure out what type myVariable should will be.

Maybe you can use WebView, but as you can see in the doc WebView doesn't support javascript and other stuff like widgets by default.

You won't be able to do the exact thing in mySQL, the easiest thing would to probably make a view that mirrors that CTE and just select from the view. You can do it with subqueries, but that will perform really poorly. If you run into any CTEs that do recursion, I don't know how you'd be able to recreate that without using stored procedures.

EDIT: As I said in my comment, that example you posted has no need for a CTE, so you must have simplified it for the question since it can be just written as

SELECT article.*, userinfo.*, category.* FROM question
     INNER JOIN userinfo ON userinfo.user_userid=article.article_ownerid
     INNER JOIN category ON article.article_categoryid=category.catid
     WHERE article.article_isdeleted = 0
 ORDER BY article_date DESC Limit 1, 3

you should add header like this

#include <another.c>

note : both file should placed in same place

I know this is years later but I ran into the same problem. The solution I found was to change the window title in main.cpp. I guess once the w.show(); is called the window title can no longer be changed. In my case I just wanted the title to reflect the current directory and it works.

int main(int argc, char *argv[]) 
{
QApplication a(argc, argv);
MainWindow w;
w.setWindowTitle(QDir::currentPath());
w.show();

return a.exec();
}

I changed the import sequence without fixing the problem, until finally I installed moments and tempus dominius (Core and bootrap), using npm and include them in boostrap.js

try {
window.Popper = require('popper.js').default;
window.$ = window.jQuery = require('jquery');
require('moment'); /*added*/
require('bootstrap');
require('tempusdominus-bootstrap-4');/*added*/} catch (e) {}

In my case, putting space after colon was wrong.

Official Documentation

are you using jquery and prototype on the same page by any chance?

If so, use jquery noConflict mode, otherwise you are overwriting prototypes $ function.

noConflict mode is activated by doing the following:

<script src="jquery.js"></script>
<script>jQuery.noConflict();</script>

Note: by doing this, the dollar sign variable no longer represents the jQuery object. To keep from rewriting all your jQuery code, you can use this little trick to create a dollar sign scope for jQuery:

jQuery(function ($) {
    // The dollar sign will equal jQuery in this scope
});

// Out here, the dollar sign still equals Prototype

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })
}

You forgot to return the map. this code will resolve the issue.

Try the following code:

public static byte[] decode(String hex){

        String[] list=hex.split("(?<=\\G.{2})");
        ByteBuffer buffer= ByteBuffer.allocate(list.length);
        System.out.println(list.length);
        for(String str: list)
            buffer.put(Byte.parseByte(str,16));

        return buffer.array();

}

To convert to String just create a new String with the byte[] returned by the decode method.

Try out following:

SELECT *
FROM
  (SELECT rownum AS rn,
    a.*
  FROM
    (WITH DATA AS -- creating dummy data
    ( SELECT 'MOHAN' AS NAME, 200 AS SALARY FROM DUAL
    UNION ALL
    SELECT 'AKSHAY' AS NAME, 500 AS SALARY FROM DUAL
    UNION ALL
    SELECT 'HARI' AS NAME, 300 AS SALARY FROM DUAL
    UNION ALL
    SELECT 'RAM' AS NAME, 400 AS SALARY FROM DUAL
    )
  SELECT D.* FROM DATA D ORDER BY SALARY DESC
    ) A
  )
WHERE rn = 3; -- specify N'th highest here (In this case fetching 3'rd highest)

Cheers!

I had a similar problem with 'org.codehaus.mojo'-'jaxws-maven-plugin': could not resolve dependencies. Fortunately, I was able to do a Project > Clean in Eclipse, which resolved the issue.
