I think the simplest way it's to use library ContentManager. This library for getting photo or video from a device gallery, cloud or camera. With asynchronous load from the cloud and fixed bugs for some problem devices.

Download via Gradle: compile 'com.github.stfalcon:contentmanager:0.4.3' You can find documentation at https://github.com/stfalcon-studio/ContentManager

The EXTRA_ALLOW_MULTIPLE option is set on the intent through the Intent.putExtra() method:

intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);

Your code above should look like this:

Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,"Select Picture"), 1);

Note: the EXTRA_ALLOW_MULTIPLE option is only available in Android API 18 and higher.

EDIT: Use this Solution here: https://stackoverflow.com/a/20559175/2033223 Works perfect!

First of, thank for your solution @luizfelipetx

I changed your solution a little bit. This works for me:

public static String getRealPathFromDocumentUri(Context context, Uri uri){
    String filePath = "";

    Pattern p = Pattern.compile("(\\d+)$");
    Matcher m = p.matcher(uri.toString());
    if (!m.find()) {
        Log.e(ImageConverter.class.getSimpleName(), "ID for requested image not found: " + uri.toString());
        return filePath;
    }
    String imgId = m.group();

    String[] column = { MediaStore.Images.Media.DATA };
    String sel = MediaStore.Images.Media._ID + "=?";

    Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
            column, sel, new String[]{ imgId }, null);

    int columnIndex = cursor.getColumnIndex(column[0]);

    if (cursor.moveToFirst()) {
        filePath = cursor.getString(columnIndex);
    }
    cursor.close();

    return filePath;
}

Note: So we got documents and image, depending, if the image comes from 'recents', 'gallery' or what ever. So I extract the image ID first before looking it up.

The EOF flag is only set after a read operation attempts to read past the end of the file. get() is returning the symbolic constant traits::eof() (which just happens to equal -1) because it reached the end of the file and could not read any more data, and only at that point will eof() be true. If you want to check for this condition, you can do something like the following:

int ch;
while ((ch = inf.get()) != EOF) {
    std::cout << static_cast<char>(ch) << "\n";
}

Sounds like you're just trying to do a classic two-column lookup. http://www.dailydoseofexcel.com/archives/2009/04/21/vlookup-on-two-columns/

Tons of solutions for this, most simple is probably the following (which doesn't require an array formula):

=SUMPRODUCT((Lookup!A:A=Param!A1)*(Lookup!B:B=Param!B1)*(Lookup!C:C))

To translate your specific example, you would use:

=SUMPRODUCT((A1:A3=A2)*(B1:B3="B")*(C1:C3))

There are a lot of good answers here but I didn't find the one about using reduce method. So for your case, you can apply it in following way:

 List<Employee> employeeList = employees.stream()
      .reduce(new ArrayList<>(), (List<Employee> accumulator, Employee employee) ->
      {
        if (accumulator.stream().noneMatch(emp -> emp.getId().equals(employee.getId())))
        {
          accumulator.add(employee);
        }
        return accumulator;
      }, (acc1, acc2) ->
      {
        acc1.addAll(acc2);
        return acc1;
      });

Ehcache is a pretty good solution for this and has a way to peek (getQuiet() is the method) such that it doesn't update the idle timestamp. Internally, Ehcache is implemented with a set of maps, kind of like ConcurrentHashMap, so it has similar kinds of concurrency benefits.

int fib(int n) {
    if (n == 1 || n == 2) {
        return 1;
    } else {
        return fib(n - 1) + fib(n - 2);
    }
}

in fibonacci sequence first 2 numbers always sequels to 1 then every time the value became 1 or 2 it must return 1

There are built-in functions in Python for "right" and "left", if you are looking for a boolean result.

str = "this_is_a_test"
left = str.startswith("this")
print(left)
> True

right = str.endswith("test")
print(right)
> True

Let us assume you got the start date and end date from the UI and stored it in the scope variable in the controller.

Then declare an array which will get reset on every function call so that on the next call for the function the new data can be stored.

var dayLabel = [];

Remember to use new Date(your starting variable) because if you dont use the new date and directly assign it to variable the setDate function will change the origional variable value in each iteration`

for (var d = new Date($scope.startDate); d <= $scope.endDate; d.setDate(d.getDate() + 1)) {
                dayLabel.push(new Date(d));
            }

Here Value 1 to 10 are column names that you are getting

This should work, I think...

ResultSet results = st.executeQuery(sql);

if(results.next()) { //there is a row
 int id = results.getInt(1); //ID if its 1st column
 String str1 = results.getString(2);
 ...
}

Passsing bitmap as parceable in bundle between activity is not a good idea because of size limitation of Parceable(1mb). You can store the bitmap in a file in internal storage and retrieve the stored bitmap in several activities. Here's some sample code.

To store bitmap in a file myImage in internal storage:

public String createImageFromBitmap(Bitmap bitmap) {
    String fileName = "myImage";//no .png or .jpg needed
    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
        FileOutputStream fo = openFileOutput(fileName, Context.MODE_PRIVATE);
        fo.write(bytes.toByteArray());
        // remember close file output
        fo.close();
    } catch (Exception e) {
        e.printStackTrace();
        fileName = null;
    }
    return fileName;
}

Then in the next activity you can decode this file myImage to a bitmap using following code:

//here context can be anything like getActivity() for fragment, this or MainActivity.this
Bitmap bitmap = BitmapFactory.decodeStream(context.openFileInput("myImage"));

Note A lot of checking for null and scaling bitmap's is ommited.

My problem resolved with Option 1. Probably the simplest way is to include your helper module in your controller:

class ApplicationController < ActionController::Base
  include ApplicationHelper

...

I would still recommend Firebug. Not only it can debug JS within your JSP files, it can enhance debugging experience with addons like JS Deminifier (if your production JS is minified), FireQuery, FireRainbow and more.

There is also Firebug lite which is nothing but a bookmarklet. It lets you do limited things but still is useful.

Chrome as a developer console built-in that would let you modify javascript.

Using these tools, you should be able to inject your own JS too.

cd /path/to/backupdir/
git clone /path/to/repo
cd /path/to/repo
git remote add backup /path/to/backupdir
git push --set-upstream backup master

this creates a backup and makes the setup, so that you can do a git push to update your backup, what is probably what you want to do. Just make sure, that /path/to/backupdir and /path/to/repo are at least different hard drives, otherwise it doesn't make that much sense to do that.

You must close the project, hover over the project in the welcome screen, then press the delete button.

This is an old thread but just in case anyone comes across it like I did. pi.FileName needs to be set to the file name (and possibly full path to file ) of the executable you want to use to open your file. The below code works for me to open a video file with VLC.

var path = files[currentIndex].fileName;
var pi = new ProcessStartInfo(path)
{
    Arguments = Path.GetFileName(path),
    UseShellExecute = true,
    WorkingDirectory = Path.GetDirectoryName(path),
    FileName = "C:\\Program Files (x86)\\VideoLAN\\VLC\\vlc.exe",
    Verb = "OPEN"
};
Process.Start(pi)

Tigran's answer works but will use windows' default application to open your file, so using ProcessStartInfo may be useful if you want to open the file with an application that is not the default.

For the future time traveler from google, here is a new way (available from python 3.8 onward):

b = 1
if a := b:
    # this section is only reached if b is not 0 or false.
    # Also, a is set to b
    print(a, b)

The doxypy input filter allows you to use pretty much all of Doxygen's formatting tags in a standard Python docstring format. I use it to document a large mixed C++ and Python game application framework, and it's working well.

The extra [ ] on the outside of your second syntax are unnecessary, and possibly confusing. You may use them, but if you must you need to have whitespace between them.

Alternatively:

while [ $stats -gt 300 ] || [ $stats -eq 0 ]

Just watch out for any spaces or errors in your arguments/command. The mvn error message may not be so descriptive but I have realised, usually spaces/omissions can also cause that error.

Most answers you find on contenteditable cursor positioning are fairly simplistic in that they only cater for inputs with plain vanilla text. Once you using html elements within the container the text entered gets split into nodes and distributed liberally across a tree structure.

To set the cursor position I have this function which loops round all the child text nodes within the supplied node and sets a range from the start of the initial node to the chars.count character:

function createRange(node, chars, range) {
    if (!range) {
        range = document.createRange()
        range.selectNode(node);
        range.setStart(node, 0);
    }

    if (chars.count === 0) {
        range.setEnd(node, chars.count);
    } else if (node && chars.count >0) {
        if (node.nodeType === Node.TEXT_NODE) {
            if (node.textContent.length < chars.count) {
                chars.count -= node.textContent.length;
            } else {
                range.setEnd(node, chars.count);
                chars.count = 0;
            }
        } else {
           for (var lp = 0; lp < node.childNodes.length; lp++) {
                range = createRange(node.childNodes[lp], chars, range);

                if (chars.count === 0) {
                    break;
                }
            }
        }
    } 

    return range;
};

I then call the routine with this function:

function setCurrentCursorPosition(chars) {
    if (chars >= 0) {
        var selection = window.getSelection();

        range = createRange(document.getElementById("test").parentNode, { count: chars });

        if (range) {
            range.collapse(false);
            selection.removeAllRanges();
            selection.addRange(range);
        }
    }
};

The range.collapse(false) sets the cursor to the end of the range. I've tested it with the latest versions of Chrome, IE, Mozilla and Opera and they all work fine.

PS. If anyone is interested I get the current cursor position using this code:

function isChildOf(node, parentId) {
    while (node !== null) {
        if (node.id === parentId) {
            return true;
        }
        node = node.parentNode;
    }

    return false;
};

function getCurrentCursorPosition(parentId) {
    var selection = window.getSelection(),
        charCount = -1,
        node;

    if (selection.focusNode) {
        if (isChildOf(selection.focusNode, parentId)) {
            node = selection.focusNode; 
            charCount = selection.focusOffset;

            while (node) {
                if (node.id === parentId) {
                    break;
                }

                if (node.previousSibling) {
                    node = node.previousSibling;
                    charCount += node.textContent.length;
                } else {
                     node = node.parentNode;
                     if (node === null) {
                         break
                     }
                }
           }
      }
   }

    return charCount;
};

The code does the opposite of the set function - it gets the current window.getSelection().focusNode and focusOffset and counts backwards all text characters encountered until it hits a parent node with id of containerId. The isChildOf function just checks before running that the suplied node is actually a child of the supplied parentId.

The code should work straight without change, but I have just taken it from a jQuery plugin I've developed so have hacked out a couple of this's - let me know if anything doesn't work!

In Java, you can verify using Object utils.

import static java.util.Objects.isNull;
if(IsNull(yourObject)){
  //your block here
}

One of the best posts I've ever come across regarding Security as it relates to REST is over at 1 RainDrop. The MySpace API's use OAuth also for security and you have full access to their custom channels in the RestChess code, which I did a lot of exploration with. This was demo'd at Mix and you can find the posting here.

You can use the excecl command

int execl(const char *path, const char *arg, ...);

Like shown here

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>

int main (void) {

   return execl ("/bin/pwd", "pwd", NULL);

}

The second argument will be the name of the process as it will appear in the process table.

Alternatively, you can use the getcwd() function to get the current working directory:

#include <stdio.h>
#include <unistd.h>
#include <dirent.h>
#define MAX 255

int main (void) {
char wd[MAX];
wd[MAX-1] = '\0';

if(getcwd(wd, MAX-1) == NULL) {
  printf ("Can not get current working directory\n");
}
else {
  printf("%s\n", wd);
}
  return 0;
}

public static bool RegistryValueExists(string hive_HKLM_or_HKCU, string registryRoot, string valueName)
{
    RegistryKey root;
    switch (hive_HKLM_or_HKCU.ToUpper())
    {
        case "HKLM":
            root = Registry.LocalMachine.OpenSubKey(registryRoot, false);
            break;
        case "HKCU":
            root = Registry.CurrentUser.OpenSubKey(registryRoot, false);
            break;
        default:
            throw new System.InvalidOperationException("parameter registryRoot must be either \"HKLM\" or \"HKCU\"");
    }

    return root.GetValue(valueName) != null;
}

Click here this is a good tutorial for both window/ubuntu.

1. apktool1.5.1.jar download from here.

2. apktool-install-linux-r05-ibot download from here.

3. dex2jar-0.0.9.15.zip download from here.

4. jd-gui-0.3.3.linux.i686.tar.gz (java de-complier) download from here.

5. framework-res.apk ( Located at your android device /system/framework/)

Procedure:

1. Rename the .apk file and change the extension to .zip ,

it will become .zip.

2. Then extract .zip.

3. Unzip downloaded dex2jar-0.0.9.15.zip file , copy the contents and paste it to unzip folder.

4. Open terminal and change directory to unzip “dex2jar-0.0.9.15 “

– cd – sh dex2jar.sh classes.dex (result of this command “classes.dex.dex2jar.jar” will be in your extracted folder itself).

5. Now, create new folder and copy “classes.dex.dex2jar.jar” into it.

6. Unzip “jd-gui-0.3.3.linux.i686.zip“ and open up the “Java Decompiler” in full screen mode.

7. Click on open file and select “classes.dex.dex2jar.jar” into the window.

8. “Java Decompiler” and go to file > save and save the source in a .zip file.

9. Create “source_code” folder.

10. Extract the saved .zip and copy the contents to “source_code” folder.

11. This will be where we keep your source code.

12. Extract apktool1.5.1.tar.bz2 , you get apktool.jar

13. Now, unzip “apktool-install-linux-r05-ibot.zip”

14. Copy “framework-res.apk” , “.apk” and apktool.jar

15. Paste it to the unzip “apktool-install-linux-r05-ibot” folder (line no 13).

16. Then open terminal and type:

    – cd

    – chown -R : ‘apktool.jar’

    – chown -R : ‘apktool’

    – chown -R : ‘aapt’

    – sudo chmod +x ‘apktool.jar’

    – sudo chmod +x ‘apktool’

    – sudo chmod +x ‘aapt’

    – sudo mv apktool.jar /usr/local/bin

    – sudo mv apktool /usr/local/bin

    – sudo mv aapt /usr/local/bin

    – apktool if framework-res.apk – apktool d .apk

I took a different approach. I switched to use $.post and the error has gone since then.

The Timeout was easy enough to find a solution for, but the Interval was a little bit trickier.

I came up with the following two classes to solve this issues:

function PauseableTimeout(func, delay){
    this.func = func;

    var _now = new Date().getTime();
    this.triggerTime = _now + delay;

    this.t = window.setTimeout(this.func,delay);

    this.paused_timeLeft = 0;

    this.getTimeLeft = function(){
        var now = new Date();

        return this.triggerTime - now;
    }

    this.pause = function(){
        this.paused_timeLeft = this.getTimeLeft();

        window.clearTimeout(this.t);
        this.t = null;
    }

    this.resume = function(){
        if (this.t == null){
            this.t = window.setTimeout(this.func, this.paused_timeLeft);
        }
    }

    this.clearTimeout = function(){ window.clearTimeout(this.t);}
}

function PauseableInterval(func, delay){
    this.func = func;
    this.delay = delay;

    this.triggerSetAt = new Date().getTime();
    this.triggerTime = this.triggerSetAt + this.delay;

    this.i = window.setInterval(this.func, this.delay);

    this.t_restart = null;

    this.paused_timeLeft = 0;

    this.getTimeLeft = function(){
        var now = new Date();
        return this.delay - ((now - this.triggerSetAt) % this.delay);
    }

    this.pause = function(){
        this.paused_timeLeft = this.getTimeLeft();
        window.clearInterval(this.i);
        this.i = null;
    }

    this.restart = function(sender){
        sender.i = window.setInterval(sender.func, sender.delay);
    }

    this.resume = function(){
        if (this.i == null){
            this.i = window.setTimeout(this.restart, this.paused_timeLeft, this);
        }
    }

    this.clearInterval = function(){ window.clearInterval(this.i);}
}

These can be implemented as such:

var pt_hey = new PauseableTimeout(function(){
    alert("hello");
}, 2000);

window.setTimeout(function(){
    pt_hey.pause();
}, 1000);

window.setTimeout("pt_hey.start()", 2000);

This example will set a pauseable Timeout (pt_hey) which is scheduled to alert, "hey" after two seconds. Another Timeout pauses pt_hey after one second. A third Timeout resumes pt_hey after two seconds. pt_hey runs for one second, pauses for one second, then resumes running. pt_hey triggers after three seconds.

Now for the trickier intervals

var pi_hey = new PauseableInterval(function(){
    console.log("hello world");
}, 2000);

window.setTimeout("pi_hey.pause()", 5000);

window.setTimeout("pi_hey.resume()", 6000);

This example sets a pauseable Interval (pi_hey) to write "hello world" in the console every two seconds. A timeout pauses pi_hey after five seconds. Another timeout resumes pi_hey after six seconds. So pi_hey will trigger twice, run for one second, pause for one second, run for one second, and then continue triggering every 2 seconds.

OTHER FUNCTIONS

• clearTimeout() and clearInterval()

  pt_hey.clearTimeout(); and pi_hey.clearInterval(); serve as an easy way to clear the timeouts and intervals.

• getTimeLeft()

  pt_hey.getTimeLeft(); and pi_hey.getTimeLeft(); will return how many milliseconds till the next trigger is scheduled to occur.

You can try this:

<div ng-app="app">
    <div ng-controller="AppCtrl">
        <a my-dir ng-repeat="user in users" ng-click="fxn()">{{user.name}}</a>
    </div>
</div>

<script>
var app = angular.module('app', []);

function AppCtrl($scope) {
        $scope.users = [{ name: 'John', id: 1 }, { name: 'anonymous' }];
        $scope.fxn = function () {
            alert('It works');
        };
    }

app.directive("myDir", function ($compile) {
    return {
        scope: {ngClick: '='}
    };
});
</script>

Taking DWins example.

What I often do, particularly when I use many, many different plots with the same colours or size information, is I store them in variables I otherwise never use. This helps me keep my code a little cleaner AND I can change it "globally".

E.g.

clab = 1.5
cmain = 2
caxis = 1.2

plot(1, 1 ,xlab="x axis", ylab="y axis",  pch=19,
           col.lab="red", cex.lab=clab,    
           col="green", main = "Testing scatterplots", cex.main =cmain, cex.axis=caxis) 

You can also write a function, doing something similar. But for a quick shot this is ideal. You can also store that kind of information in an extra script, so you don't have a messy plot script:

which you then call with setwd("") source("plotcolours.r")

in a file say called plotcolours.r you then store all the e.g. colour or size variables

clab = 1.5
cmain = 2
caxis = 1.2 

for colours could use

darkred<-rgb(113,28,47,maxColorValue=255)

as your variable 'darkred' now has the colour information stored, you can access it in your actual plotting script.

plot(1,1,col=darkred) 

I like to use this clean code to pass one value only:

startActivity(new Intent(context, YourActivity.class).putExtra("key","value"));

This make more simple to write and understandable code.

In short no. It is generally thought to be too dangerous to rename a database. MySQL had that feature for a bit, but it was removed. You would be better off using the workbench to export both the schema and data to SQL then changing the CREATE DATABASE name there before you run/import it.

If you are using Webdriver then the item you are looking for is Selected.

Often times in the render of the checkbox doesn't actually apply the attribute checked unless specified.

So what you would look for in Selenium Webdriver is this

isChecked = e.findElement(By.tagName("input")).Selected;

As there is no Selected in WebDriver Java API, the above code should be as follows:

isChecked = e.findElement(By.tagName("input")).isSelected();

Your questions:

Q 1.) I would like to know why it returns all the texts that following the div?
It should not and I think in will not. It returns all div with 'id' attribute value equal 'containter' (and all children of this). But you are printing the results with ele.getText() Where getText will return all text content of all children of your result.

Get the visible (i.e. not hidden by CSS) innerText of this element, including sub-elements, without any leading or trailing whitespace.
Returns:
The innerText of this element.

Q 2.) how should I modify the code so it just return first or first few nodes that follow the parent note
This is not really clear what you are looking for. Example:

<p1> <div/> </p1 <p2/> 

The following to parent of the div is p2. This would be:

 //div[@id='container'][1]/parent::*/following-sibling::* 

or shorter

 //div[@id='container'][1]/../following-sibling::* 

If you are only looking for the first one extent the expression with an "predicate" (e.g [1] - for the first one. or [position() < 4]for the first three)

If your are looking for the first child of the first div:

//div[@id='container'][1]/*[1]

If there is only one div with id an you are looking for the first child:

   //div[@id='container']/*[1]

and so on.

Windows:

Create setenv.bat and update it with following:

set SPRING_PROFILES_ACTIVE=dev

You can convert BigDecimal to double using .doubleValue(). But believe me, don't use it if you have currency manipulations. It should always be performed on BigDecimal objects directly. Precision loss in these calculations are big time problems in currency related calculations.

The kernel might be the operating system or it might be a part of the operating system. In Linux, the kernel is loaded and executed first. Then it starts up other bits of the OS (like init) to make the system useful.

This is especially true in a micro-kernel environment. The kernel has minimal functionality. Everything else, like file systems and TCP/IP, run as a user process.

In the Terminal, type:

$ curl -V

That's a capital V for the version

You can use the minsize and maxsize to set a minimum & maximum size, for example:

def __init__(self,master):
    master.minsize(width=666, height=666)
    master.maxsize(width=666, height=666)

Will give your window a fixed width & height of 666 pixels.

Or, just using minsize

def __init__(self,master):
    master.minsize(width=666, height=666)

Will make sure your window is always at least 666 pixels large, but the user can still expand the window.

you can create a arraylist, and use Collection.addAll() to convert the string array to your arraylist

I know this is not entirely the scope of the question, but if you find the need to filter only commits by a specific author, you can always pipe to grep :)

# lists all commits in chronological order that
# belong to the github account with
# username `MY_GITHUB_USERNAME` (obviously you
# would want to replace that with your github username,
# or the username you are trying to filter by)


git for-each-ref --format='%(committerdate) %09 %(authorname) %09 %(refname)' | sort -committerdate | grep 'MY_GITHUB_USERNAME'

happy coding! :)

If you want to add a reload/refresh button to DataTables 1.10 then use drawCallback.

See example below (I am using DataTables with bootstrap css)

var ref= $('#hldy_tbl').DataTable({
        "responsive": true,
        "processing":true,
        "serverSide":true,
        "ajax":{

            "type":"POST"
        },
        "drawCallback": function( settings ) {
            $('<li><a onclick="refresh_tab()" class="fa fa-refresh"></a></li>').prependTo('div.dataTables_paginate ul.pagination');
        }
    });

function refresh_tab(){

The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-" for a red line, or by explicitely stating the color argument.

import matplotlib.pyplot as plt

plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line

plt.show()

See also the plot command's documentation.

In case you already have a line with a certain color, you can change that with the lines2D.set_color() method.

line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")

import matplotlib.pyplot as plt
import pandas as pd

df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line

plt.show()

If you want to change this color later on, you can do so by

plt.gca().get_lines()[0].set_color("black")

This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them

for ax in plt.gcf().axes:
    ax.get_lines()[0].set_color("black")

and if you have more lines you can loop over them as well.

You may want to take a look at this very helpful article which covers this very nicely!

Just thought it might help people searching for a good solution to this problem.

Some browsers will include whitespace, others won't. >= is appropriate here. Otherwise equality is double equals ==

@mywolfe02 gives a static range code so his inRange works fine but if you want to add dynamic range then use this one with inRange function of him.this works better with when you want to populate data to fix starting cell and last column is also fixed.

Sub DynamicRange()

Dim sht As Worksheet
Dim LastRow As Long
Dim StartCell As Range
Dim rng As Range

Set sht = Worksheets("xyz")
LastRow = sht.Cells.Find("*", SearchOrder:=xlByRows, SearchDirection:=xlPrevious).row
Set rng = Workbooks("Record.xlsm").Worksheets("xyz").Range(Cells(12, 2), Cells(LastRow, 12))

Debug.Print LastRow

If InRange(ActiveCell, rng) Then
'        MsgBox "Active Cell In Range!"
  Else
      MsgBox "Please select the cell within the range!"
  End If

React behavior

Apart from the rest of the answers, I would like to show one difference in React.

If I throw a new Error() and I am in development mode, I will get an error screen and a console log. If I throw a string literal, I will only see it in the console and possibly miss it, if I am not watching the console log.

Example

Throwing an error logs into the console and shows an error screen while in development mode (the screen won't be visible in production).

throw new Error("The application could not authenticate.");

Whereas the following code only logs into the console:

throw "The application could not authenticate.";

document.evaluate() (DOM Level 3 XPath) is supported in Firefox, Chrome, Safari and Opera - the only major browser missing is MSIE. Nevertheless, jQuery supports basic XPath expressions: http://docs.jquery.com/DOM/Traversing/Selectors#XPath_Selectors (moved into a plugin in the current jQuery version, see https://plugins.jquery.com/xpath/). It simply converts XPath expressions into equivalent CSS selectors however.

If you want to learn more about regular expressions - or just need a handy reference - the Wikipedia Entry on Regular Expressions is actually pretty good.

The object keyword creates a new singleton type, which is like a class that only has a single named instance. If you’re familiar with Java, declaring an object in Scala is a lot like creating a new instance of an anonymous class.

Scala has no equivalent to Java’s static keyword, and an object is often used in Scala where you might use a class with static members in Java.

Yes, there is a way to write to the event log you are looking for. You don't need to create a new source, just simply use the existent one, which often has the same name as the EventLog's name and also, in some cases like the event log Application, can be accessible without administrative privileges*.

*Other cases, where you cannot access it directly, are the Security EventLog, for example, which is only accessed by the operating system.

I used this code to write directly to the event log Application:

using (EventLog eventLog = new EventLog("Application")) 
{
    eventLog.Source = "Application"; 
    eventLog.WriteEntry("Log message example", EventLogEntryType.Information, 101, 1); 
}

As you can see, the EventLog source is the same as the EventLog's name. The reason of this can be found in Event Sources @ Windows Dev Center (I bolded the part which refers to source name):

Each log in the Eventlog key contains subkeys called event sources. The event source is the name of the software that logs the event. It is often the name of the application or the name of a subcomponent of the application if the application is large. You can add a maximum of 16,384 event sources to the registry.

Use and empty() whit negation (for test if not empty)

if(!empty($_GET['id'])) {
    // if get id is not empty
}

This does not meet all of the requirements of RFCs 5321 and 5322, but it works with the following definitions.

@"^([0-9a-zA-Z]([\+\-_\.][0-9a-zA-Z]+)*)+"@(([0-9a-zA-Z][-\w]*[0-9a-zA-Z]*\.)+[a-zA-Z0-9]{2,17})$";

Below is the code

You may append HTML <br /> in between your lines. Something like:

MyLabel.Text = "SomeText asdfa asd fas df asdf" + "<br />" + "Some more text";

With StringBuilder you can try:

StringBuilder sb = new StringBuilder();
sb.AppendLine("Some text with line one");
sb.AppendLine("Some mpre text with line two");
MyLabel.Text = sb.ToString().Replace(Environment.NewLine, "<br />");

From my experience, sudo apt-get install gcc-multilib g++-multilib helps. But my another issue is that I FORGET to clean the directory so I still get the same error. It is the first time to use clang or cmake. So I just delete my original directory and re-compile and it works. Hope it helps someone like me.

If all you want to do is store some static values in a lookup table, you can use an Object Literal (the same format used by JSON) to do it compactly:

var table = { one: [1,10,5], two: [2], three: [3, 30, 300] }

And then access them using JavaScript's associative array syntax:

alert(table['one']);    // Will alert with [1,10,5]
alert(table['one'][1]); // Will alert with 10

As an addition to above answers, you may use set_time_limit() function:

General purpose normalisation function to format any timestamp from any timezone to other. Very useful for storing datetimestamps of users from different timezones in a relational database. For database comparisons store timestamp as UTC and use with gmdate('Y-m-d H:i:s')

/**
 * Convert Datetime from any given olsonzone to other.
 * @return datetime in user specified format
 */

function datetimeconv($datetime, $from, $to)
{
    try {
        if ($from['localeFormat'] != 'Y-m-d H:i:s') {
            $datetime = DateTime::createFromFormat($from['localeFormat'], $datetime)->format('Y-m-d H:i:s');
        }
        $datetime = new DateTime($datetime, new DateTimeZone($from['olsonZone']));
        $datetime->setTimeZone(new DateTimeZone($to['olsonZone']));
        return $datetime->format($to['localeFormat']);
    } catch (\Exception $e) {
        return null;
    }
}

Usage:

$from = ['localeFormat' => "d/m/Y H:i A", 'olsonZone' => 'Asia/Calcutta'];

$to = ['localeFormat' => "Y-m-d H:i:s", 'olsonZone' => 'UTC'];

datetimeconv("14/05/1986 10:45 PM", $from, $to); // returns "1986-05-14 17:15:00"

You need to use cast. I see the other answers, and they will really work, but as the tag is C++ I'd suggest you to use static_cast:

float m = static_cast< float >( a.y - b.y ) / static_cast< float >( a.x - b.x );

When using NOT IN you should ensure that none of the values are NULL:

SELECT mac, creation_date 
FROM logs 
WHERE logs_type_id=11
AND mac NOT IN (
    SELECT mac
    FROM consols
    WHERE mac IS NOT NULL -- add this
)

If you're writing code that you envisage is going to be compiled on a wide variety of platforms, with a number of different compilers, then using these flags yourself will help to ensure you don't produce code that only compiles under GCC.

The solution was installing it by running this command:

Install-PackageProvider -Name NuGet -MinimumVersion 2.8.5.201 -Force

If that fails with the error below you can copy/paste the NuGet folder from another PC (admin needed): C:\Program Files\PackageManagement\ProviderAssemblies\NuGet:

The major difference between Page_Load and Page_PreRender is that in the Page_Load method not all of your page controls are completely initialized (loaded), because individual controls Load() methods has not been called yet. This means that tree is not ready for rendering yet. In Page_PreRender you guaranteed that all page controls are loaded and ready for rendering. Technically Page_PreRender is your last chance to tweak the page before it turns into HTML stream.

Wikipedia has this to say about the differences.

In general JScript is an ActiveX scripting language that is probably interpreted as JavaScript by non-IE browsers.

Another way to get to the deleted commit is with the git fsck command.

git fsck --lost-found

This will output something like at the last line:

dangling commit xyz

We can check that it is the same commit using reflog as suggested in other answers. Now we can do a git merge

git merge xyz

Note:
We cannot get the commit back with fsck if we have already run a git gc command which will remove the reference to the dangling commit.

I was testing a function that had multiple UPDATE statements within IF-ELSE blocks.

I was testing all possible paths, so I reset the tables to their previous values with 'manual' UPDATE statements each time before running the function again.

I noticed that the issue would happen just after those UPDATE statements;

I added a COMMIT; after the UPDATE statement I used to reset the tables and that solved the problem.

So, caution, the problem was not the function itself...

take this code to you .htaccess file Redirect HTTP to HTTPS automatically

RewriteEngine On RewriteCond %{HTTPS} off RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

If you want to get source map file different version, you can use this link http://code.jquery.com/jquery-x.xx.x.min.map

Instead x.xx.x put your version number.

Note: Some links, which you get on this method, may be broken :)

You use it when you have lots of options to deal with. Think about things like jmock:

m.expects(once())
    .method("testMethod")
    .with(eq(1), eq(2))
    .returns("someResponse");

It feels a lot more natural and is...possible.

There's also xml building, string building and many other things. Imagine if java.util.Map had put as a builder. You could do stuff like this:

Map<String, Integer> m = new HashMap<String, Integer>()
    .put("a", 1)
    .put("b", 2)
    .put("c", 3);

From the command prompt, use the Windows "sc.exe" utility. You will run something like this:

sc delete <service-name>

next() does not work in your case because you first call readlines() which basically sets the file iterator to point to the end of file.

Since you are reading in all the lines anyway you can refer to the next line using an index:

filne = "in"
with open(filne, 'r+') as f:
    lines = f.readlines()
    for i in range(0, len(lines)):
        line = lines[i]
        print line
        if line[:5] == "anim ":
            ne = lines[i + 1] # you may want to check that i < len(lines)
            print ' ne ',ne,'\n'
            break

Loop through the list in reverse order, and use the .splice method.

var array = ['A', 'B', 'C']; // Test
var search_term = 'B';

for (var i=array.length-1; i>=0; i--) {
    if (array[i] === search_term) {
        array.splice(i, 1);
        // break;       //<-- Uncomment  if only the first term has to be removed
    }
}

The reverse order is important when all occurrences of the search term has to be removed. Otherwise, the counter will increase, and you will skip elements.

When only the first occurrence has to be removed, the following will also work:

var index = array.indexOf(search_term);    // <-- Not supported in <IE9
if (index !== -1) {
    array.splice(index, 1);
}

I tried the solutions above and it looks like on rails 5.* the second agument by default is the value of the input form, what worked for me was:

text_field_tag :attr, "", placeholder: "placeholder text"

In my case I had a list of jobs that I wanted to run in async from my main method, have been using this in production for quite sometime and works fine.

We can consider a telephone call In that Number is wsdl and exchange of information is soap.

WSDL is description how to connect with communication server.SOAP is have communication messages.

An example where things could go wrong with Shell=True is shown here

>>> from subprocess import call
>>> filename = input("What file would you like to display?\n")
What file would you like to display?
non_existent; rm -rf / # THIS WILL DELETE EVERYTHING IN ROOT PARTITION!!!
>>> call("cat " + filename, shell=True) # Uh-oh. This will end badly...

Check the doc here: subprocess.call()

here you go get_the_category( $post->ID ); will return the array of categories of that post you need to loop through the array

$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}

get_the_category

Use this:

String x = "00123".replaceAll("^0*", ""); // -> 123

I was able to import the module within the function (only) that would require the objects from this module:

Had the same issue in Chrome and it did not go away after applying all the known remedies. For me the resolution was to uncheck "Enable phishing and malware protection" in Chrome settings (Settings -> Show advanced settings -> Privacy). After that localhost is lightningfast.

We all know that PHP save errors in php_errors.log file.

But, that file contains a lot of data.

If we want to log our application data, we need to save it to a custom location.

We can use two parameters in the error_log function to achieve this.

http://php.net/manual/en/function.error-log.php

We can do it using:

error_log(print_r($v, TRUE), 3, '/var/tmp/errors.log');

Where,

print_r($v, TRUE) : logs $v (array/string/object) to log file. 3: Put log message to custom log file specified in the third parameter.

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS).

OR, you can use file_put_contents()

file_put_contents('/var/tmp/e.log', print_r($v, true), FILE_APPEND);

Where:

'/var/tmp/errors.log': Custom log file (This path is for Linux, we can specify other depending upon OS). print_r($v, TRUE) : logs $v (array/string/object) to log file. FILE_APPEND: Constant parameter specifying whether to append to the file if it exists, if file does not exist, new file will be created.

2020 ANSWER

You can use the native .toLocaleDateString() function which supports several useful params like locale (to select a format like MM/DD/YYYY or YYYY/MM/DD), timezone (to convert the date) and formats details options (eg: 1 vs 01 vs January).

Examples

new Date().toLocaleDateString() // 8/19/2020

new Date().toLocaleDateString('en-US', {year: 'numeric', month: '2-digit', day: '2-digit'}); // 08/19/2020 (month and day with two digits)

new Date().toLocaleDateString('en-ZA'); // 2020/08/19 (year/month/day) notice the different locale

new Date().toLocaleDateString('en-CA'); // 2020-08-19 (year-month-day) notice the different locale

new Date().toLocaleString("en-US", {timeZone: "America/New_York"}); // 8/19/2020, 9:29:51 AM. (date and time in a specific timezone)

new Date().toLocaleString("en-US", {hour: '2-digit', hour12: false, timeZone: "America/New_York"});  // 09 (just the hour)

Notice that sometimes to output a date in your specific desire format, you have to find a compatible locale with that format. You can find the locale examples here: https://www.w3schools.com/jsref/tryit.asp?filename=tryjsref_tolocalestring_date_all

Please notice that locale just change the format, if you want to transform a specific date to a specific country or city time equivalent then you need to use the timezone param.

Here is the answer in Razor syntax

    <tbody>
    @foreach(System.Data.DataRow row in Model.Rows)
    {
       <tr>
          @foreach (var cell in row.ItemArray)
          {
             <td>@cell.ToString()</td>
          }
       </tr>
    }      
    </tbody>

The way to do this is by using background-size so in your case:

background-size: 50% 50%;

or

You can set the width and the height of the elements to percentages as well

I am using justify-content-center class to a row within a container. Works well with Bootstrap 4.

<div class="container-fluid">
  <div class="row justify-content-center">
   <img src="logo.png" />
  </div>
</div>

<html>
<head>
    <script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
    <script>
    $( document ).ready(function() {
        alert( "document loaded" );
    });

    $( window ).load(function() {
        alert( "window loaded" );
    });
    </script>
</head>
<body>
    <iframe src="http://stackoverflow.com"></iframe>
</body>
</html>

window.load will be triggered after all the iframe content is loaded

A great option is to use jQuery/AJAX. Look at these examples and try them out on your server. In this example, in FILE1.php, note that it is passing a blank value. You can pass a value if you wish, which might look something like this (assuming javascript vars called username and password:

data: 'username='+username+'&password='+password,

In the FILE2.php example, you would retrieve those values like this:

$uname = $_POST['username'];
$pword = $_POST['password'];

Then do your MySQL lookup and return the values thus:

echo 'You are logged in';

This would deliver the message You are logged in to the success function in FILE1.php, and the message string would be stored in the variable called "data". Therefore, the alert(data); line in the success function would alert that message. Of course, you can echo anything that you like, even large amounts of HTML, such as entire table structures.

Here is another good example to review.

The approach is to create your form, and then use jQuery to detect the button press and submit the data to a secondary PHP file via AJAX. The above examples show how to do that.

The secondary PHP file receives the variables (if any are sent) and returns a response (whatever you choose to send). That response then appears in the Success: section of your AJAX call as "data" (in these examples).

The jQuery/AJAX code is javascript, so you have two options: you can place it within <script type="text/javascript"></script> tags within your main PHP document, or you can <?php include "my_javascript_stuff.js"; ?> at the bottom of your PHP document. If you are using jQuery, don't forget to include the jQuery library as in the examples given.

In your case, it sounds like you can pretty much mirror the first example I suggested, sending no data and receiving the response in the AJAX success function. Whatever you need to do with that data, though, you must do inside the success function. Seems a bit weird at first, but it works.

Since beta.16 the parameters are not passed as array to the transform() method anymore but instead as individual parameters:

{{ myData | date:'fullDate':'arg1':'arg2' }}


export class DatePipe implements PipeTransform {    
  transform(value:any, arg1:any, arg2:any):any {
        ...
}

https://github.com/angular/angular/blob/master/CHANGELOG.md#200-beta16-2016-04-26

pipes now take a variable number of arguments, and not an array that contains all arguments.

SELECT to_char(emp_login_date,'DD-MON-YYYY HH24:MI:SS'),A.* 
FROM emp_log A
WHERE emp_login_date BETWEEN to_date(to_char('21-MAY-2015 11:50:14'),'DD-MON-YYYY HH24:MI:SS')
AND
to_date(to_char('22-MAY-2015 17:56:52'),'DD-MON-YYYY HH24:MI:SS') 
ORDER BY emp_login_date

Based on @baruch-even answer, you can delete search term on ESC double press while in normal mode with:

nnoremap <esc> :let @/ = ""<return><esc>
nnoremap <esc>^[ <esc>^[

This one was a hard nut to crack, so for the record:

To solve this, it required a custom KeyManager and a SSLSocketFactory that uses this custom KeyManager to access the separated KeyStore. I found the base code for this KeyStore and SSLFactory on this excellent blog entry: how-to-dynamically-select-a-certificate-alias-when-invoking-web-services

Then, the specialized SSLSocketFactory needs to be inserted into the WebService context:

service = getWebServicePort(getWSDLLocation());
BindingProvider bindingProvider = (BindingProvider) service; 
bindingProvider.getRequestContext().put("com.sun.xml.internal.ws.transport.https.client.SSLSocketFactory", getCustomSocketFactory()); 

Where the getCustomSocketFactory() returns a SSLSocketFactory created using the method mentioned above. This would only work for JAX-WS RI from the Sun-Oracle impl built into the JDK, given that the string indicating the SSLSocketFactory property is proprietary for this implementation.

At this stage, the JAX-WS service communication is secured through SSL, but if you are loading the WSDL from the same secure server () then you'll have a bootstrap problem, as the HTTPS request to gather the WSDL will not be using the same credentials than the Web Service. I worked around this problem by making the WSDL locally available (file:///...) and dynamically changing the web service endpoint: (a good discussion on why this is needed can be found in this forum)

bindingProvider.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, webServiceLocation); 

Now the WebService gets bootstrapped and is able to communicate through SSL with the server counterpart using a named (alias) Client-Certificate and mutual authentication. ?

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

You probably don't have the INTERNET permission. Try adding this to your AndroidManifest.xml file, right before </manifest>:

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

^{Note: the above doesn't have to be right before the </manifest> tag, but that is a good / correct place to put it.}

^{Note: if this answer doesn't help in your case, read the other answers!}

I had the same problem.

I solved it by changing selinux status to permissive with below command:

If you want to add custom ObjectMapper for registering custom serializers, try my answer.

In my case (Spring 3.2.4 and Jackson 2.3.1), XML configuration for custom serializer:

<mvc:annotation-driven>
    <mvc:message-converters register-defaults="false">
        <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <property name="objectMapper">
                <bean class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
                    <property name="serializers">
                        <array>
                            <bean class="com.example.business.serializer.json.CustomObjectSerializer"/>
                        </array>
                    </property>
                </bean>
            </property>
        </bean>
    </mvc:message-converters>
</mvc:annotation-driven>

was in unexplained way overwritten back to default by something.

This worked for me:

CustomObject.java

@JsonSerialize(using = CustomObjectSerializer.class)
public class CustomObject {

    private Long value;

    public Long getValue() {
        return value;
    }

    public void setValue(Long value) {
        this.value = value;
    }
}

CustomObjectSerializer.java

public class CustomObjectSerializer extends JsonSerializer<CustomObject> {

    @Override
    public void serialize(CustomObject value, JsonGenerator jgen,
        SerializerProvider provider) throws IOException,JsonProcessingException {
        jgen.writeStartObject();
        jgen.writeNumberField("y", value.getValue());
        jgen.writeEndObject();
    }

    @Override
    public Class<CustomObject> handledType() {
        return CustomObject.class;
    }
}

No XML configuration (<mvc:message-converters>(...)</mvc:message-converters>) is needed in my solution.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

If anyone wonders how to this for clustermap CorrGrids (part of a given seaborn example):

import seaborn as sns
import matplotlib.pyplot as plt
sns.set(context="paper", font="monospace")

# Load the datset of correlations between cortical brain networks
df = sns.load_dataset("brain_networks", header=[0, 1, 2], index_col=0)
corrmat = df.corr()

# Set up the matplotlib figure
f, ax = plt.subplots(figsize=(12, 9))

# Draw the heatmap using seaborn
g=sns.clustermap(corrmat, vmax=.8, square=True)
rotation = 90 
for i, ax in enumerate(g.fig.axes):   ## getting all axes of the fig object
     ax.set_xticklabels(ax.get_xticklabels(), rotation = rotation)


g.fig.show()

I ended up doing this

typeof ($('#mySelector').data('events').click) == "object"

Basic Usage

First, let's see what each function does:

regexObject.test( String )

Executes the search for a match between a regular expression and a specified string. Returns true or false.

string.match( RegExp )

Used to retrieve the matches when matching a string against a regular expression. Returns an array with the matches or null if there are none.

Since null evaluates to false,

if ( string.match(regex) ) {
  // There was a match.
} else {
  // No match.
} 

Performance

Is there any difference regarding performance?

Yes. I found this short note in the MDN site:

If you need to know if a string matches a regular expression regexp, use regexp.test(string).

Is the difference significant?

The answer once more is YES! This jsPerf I put together shows the difference is ~30% - ~60% depending on the browser:

Conclusion

Use .test if you want a faster boolean check. Use .match to retrieve all matches when using the g global flag.

I stumbled over this thread searching for answer to similar case. Basically all answers are found, but it's still hard to extract the essentials from them.

Kinds of Access

Assume a class Foo probably derived from some other class(es) with probably more classes derived from it.

Then accessing

• from static method/getter of Foo
  • some probably overridden static method/getter:
    • this.method()
    • this.property
  • some probably overridden instance method/getter:
    • impossible by design
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • impossible by design
• from instance method/getter of Foo
  • some probably overridden static method/getter:
    • this.constructor.method()
    • this.constructor.property
  • some probably overridden instance method/getter:
    • this.method()
    • this.property
  • own non-overridden static method/getter:
    • Foo.method()
    • Foo.property
  • own non-overridden instance method/getter:
    • not possible by intention unless using some workaround:
      • Foo.prototype.method.call( this )
      • Object.getOwnPropertyDescriptor( Foo.prototype,"property" ).get.call(this);

Keep in mind that using this isn't working this way when using arrow functions or invoking methods/getters explicitly bound to custom value.

Background

• When in context of an instance's method or getter
  • this is referring to current instance.
  • super is basically referring to same instance, but somewhat addressing methods and getters written in context of some class current one is extending (by using the prototype of Foo's prototype).
  • definition of instance's class used on creating it is available per this.constructor.
• When in context of a static method or getter there is no "current instance" by intention and so
  • this is available to refer to the definition of current class directly.
  • super is not referring to some instance either, but to static methods and getters written in context of some class current one is extending.

Check out Apache Ant

It's possible to use Ant for automatic builds with eclipse, here's how

I think your best bet would be to use a combination of absolute and relative positioning.

Here's a fiddle: http://jsfiddle.net/PKVza/2/

given your html:

<div class="row">
    <div class="col-sm-6">
        <img src="~/Images/MyLogo.png" alt="Logo" />
    </div>
    <div class="bottom-align-text col-sm-6">
        <h3>Some Text</h3>
    </div>
</div>

use the following CSS:

@media (min-width: 768px ) {
  .row {
      position: relative;
  }

  .bottom-align-text {
    position: absolute;
    bottom: 0;
    right: 0;
  }
}

EDIT - Fixed CSS and JSFiddle for mobile responsiveness and changed the ID to a class.

Here is the very simple example of CSV import using threading. (Library inclusion may differ for different purpose.)

Helper Functions:

from threading import Thread
from project import app
import csv


def import_handler(csv_file_name):
    thr = Thread(target=dump_async_csv_data, args=[csv_file_name])
    thr.start()

def dump_async_csv_data(csv_file_name):
    with app.app_context():
        with open(csv_file_name) as File:
            reader = csv.DictReader(File)
            for row in reader:
                # DB operation/query

Driver Function:

import_handler(csv_file_name)

Use a parameter array with the params modifier:

public static int AddUp(params int[] values)
{
    int sum = 0;
    foreach (int value in values)
    {
        sum += value;
    }
    return sum;
}

If you want to make sure there's at least one value (rather than a possibly empty array) then specify that separately:

public static int AddUp(int firstValue, params int[] values)

(Set sum to firstValue to start with in the implementation.)

Note that you should also check the array reference for nullity in the normal way. Within the method, the parameter is a perfectly ordinary array. The parameter array modifier only makes a difference when you call the method. Basically the compiler turns:

int x = AddUp(4, 5, 6);

into something like:

int[] tmp = new int[] { 4, 5, 6 };
int x = AddUp(tmp);

You can call it with a perfectly normal array though - so the latter syntax is valid in source code as well.

Detecting CSS 3D transforms

Modernizr can detect CSS 3D transforms, yeah. The truthiness of Modernizr.csstransforms3d will tell you if the browser supports them.

The above link lets you select which tests to include in a Modernizr build, and the option you're looking for is available there.

Detecting IE specifically

Alternatively, as user356990 answered, you can use conditional comments if you're searching for IE and IE alone. Rather than creating a global variable, you can use HTML5 Boilerplate's <html> conditional comments trick to assign a class:

<!--[if lt IE 7]>      <html class="no-js lt-ie9 lt-ie8 lt-ie7"> <![endif]-->
<!--[if IE 7]>         <html class="no-js lt-ie9 lt-ie8"> <![endif]-->
<!--[if IE 8]>         <html class="no-js lt-ie9"> <![endif]-->
<!--[if gt IE 8]><!--> <html class="no-js"> <!--<![endif]-->

If you already have jQuery initialised, you can just check with $('html').hasClass('lt-ie9'). If you need to check which IE version you're in so you can conditionally load either jQuery 1.x or 2.x, you can do something like this:

myChecks.ltIE9 = (function(){
    var htmlElemClasses = document.querySelector('html').className.split(' ');
    if (!htmlElemClasses){return false;}
    for (var i = 0; i < htmlElemClasses.length; i += 1 ){
      var klass = htmlElemClasses[i];
      if (klass === 'lt-ie9'){
        return true;
      }
    }
    return false;
}());

N.B. IE conditional comments are only supported up to IE9 inclusive. From IE10 onwards, Microsoft encourages using feature detection rather than browser detection.

Whichever method you choose, you'd then test with

if ( myChecks.ltIE9 || Modernizr.csstransforms3d ){
    // iframe or flash fallback
} 

Don't take that || literally, of course.

This might work for you...

<script type="text/javascript">
function image(img) {
    var src = img.src;
    window.open(src);
}
</script>
<img src="pond1.jpg" height="150" size="150" alt="Johnson Pond" onclick="image(this)">

Implementation of parcelable can be faster if you use paracelable plugin in android studio. search for Android Parcelable code generator

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

Another way is to stick it into the command section of the Deployment:

...
command: [ "echo", "
  option = value\n
  other_option = value\n
" ]
...

Alternatively, to make it more ConfigMap-like, use an additional Deployment that will just host that config in the command section and execute kubectl create on it while adding an unique 'version' to its name (like calculating a hash of the content) and modifying all the deployments that use that config:

...
command: [ "/usr/sbin/kubectl-apply-config.sh", "
  option = value\n
  other_option = value\n
" ]
...

I'll probably post kubectl-apply-config.sh if it ends up working.

(don't do that; it looks too bad)

System.out.print(values[i] + " ");
//in one number be printed

Yes, SERIAL is the equivalent function.

CREATE TABLE foo (
id SERIAL,
bar varchar);

INSERT INTO foo (bar) values ('blah');
INSERT INTO foo (bar) values ('blah');

SELECT * FROM foo;

1,blah
2,blah

SERIAL is just a create table time macro around sequences. You can not alter SERIAL onto an existing column.

Another option would be as the return value for the stored procedure (I don't suggest this though, as that's usually best for error values).

I've included it as both when it's inserting a single row in cases where the stored procedure was being consumed by both other SQL procedures and a front-end which couldn't work with OUTPUT parameters (IBATIS in .NET I believe):

CREATE PROCEDURE My_Insert
    @col1            VARCHAR(20),
    @new_identity    INT    OUTPUT
AS
BEGIN
    SET NOCOUNT ON

    INSERT INTO My_Table (col1)
    VALUES (@col1)

    SELECT @new_identity = SCOPE_IDENTITY()

    SELECT @new_identity AS id

    RETURN
END

The output parameter is easier to work with in T-SQL when calling from other stored procedures IMO, but some programming languages have poor or no support for output parameters and work better with result sets.

when you do UNIQUE as a table level constraint as you have done then what your defining is a bit like a composite primary key see ddl constraints, here is an extract

"This specifies that the *combination* of values in the indicated columns is unique across the whole table, though any one of the columns need not be (and ordinarily isn't) unique."

this means that either field could possibly have a non unique value provided the combination is unique and this does not match your foreign key constraint.

most likely you want the constraint to be at column level. so rather then define them as table level constraints, 'append' UNIQUE to the end of the column definition like name VARCHAR(60) NOT NULL UNIQUE or specify indivdual table level constraints for each field.

The one way is by using webservice, simply write a webservice method in PHP or any other language . And From your android app by using http client request and response , you can hit the web service method which will return whatever you want.

For PHP You can create a webservice like this. Assuming below we have a php file in the server. And the route of the file is yourdomain.com/api.php

if(isset($_GET['api_call'])){
    switch($_GET['api_call']){
       case 'userlogin':
           //perform your userlogin task here
       break; 
    }
}

Now you can use Volley or Retrofit to send a network request to the above PHP Script and then, actually the php script will handle the database operation.

In this case the PHP script is called a RESTful API.

You can learn all the operation at MySQL from this tutorial. Android MySQL Tutorial to Perform CRUD.

I use this alias in .profile:

alias qclean="rabbitmqctl list_queues | python ~/bin/qclean.py"

where qclean.py has the following code:

import sys
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()

queues = sys.stdin.readlines()[1:-1]
for x in queues:
    q = x.split()[0]
    print 'Deleting %s...' %(q)
    channel.queue_delete(queue=q)

connection.close()

Essentially, this is an iterative version of code of Shweta B. Patil.

I changed @Hector Correa 's answer into an extension with generic types and also added a custom TryGetValue to it.

  public static class ListWithDuplicateExtensions
  {
    public static void Add<TKey, TValue>(this List<KeyValuePair<TKey, TValue>> collection, TKey key, TValue value)
    {
      var element = new KeyValuePair<TKey, TValue>(key, value);
      collection.Add(element);
    }

    public static int TryGetValue<TKey, TValue>(this List<KeyValuePair<TKey, TValue>> collection, TKey key, out IEnumerable<TValue> values)
    {
      values = collection.Where(pair => pair.Key.Equals(key)).Select(pair => pair.Value);
      return values.Count();
    }
  }

If it is running in the Python shell use Ctrl + Z, otherwise locate the python process and kill it.

use "-e" to specify the sed-expression

cat input.txt | sed -e 's/foo/bar/g'

Another aproach is:

let result = { ...item, location : { ...response } }

But Object spread isn't yet standardized.

Most likely .gitignore files are at play. Note that .gitignore files can appear not only at the root level of the repo, but also at any sub level. You might try this from the root level to find them:

find . -name ".gitignore"

and then examine the results to see which might be preventing your subdirs from being added.

There also might be submodules involved. Check the offending directories for ".gitmodules" files.

Similar question has been asked in stackoverflow before.

See here: PHP $_SERVER['HTTP_HOST'] vs. $_SERVER['SERVER_NAME'], am I understanding the man pages correctly?

Also see this article: http://shiflett.org/blog/2006/mar/server-name-versus-http-host

Recommended using HTTP_HOST, and falling back on SERVER_NAME only if HTTP_HOST was not set. He said that SERVER_NAME could be unreliable on the server for a variety of reasons, including:

• no DNS support
• misconfigured
• behind load balancing software

If you want to have a picture next to an url from your website someone shared on WhatsApp, you have to put a metatag on the page where the URL links to, like this:

<meta property="og:image" content="http://unrestrictedstock.com/wp-content/uploads/Unrestricted-Stock-Small.png"/>

Yes, definietly requests is great package to use in something related to HTTP requests. but we need to be careful with the encoding type of the incoming data as well below is an example which explains the difference

from requests import get

# case when the response is byte array
url = 'some_image_url'

response = get(url)
with open('output', 'wb') as file:
    file.write(response.content)


# case when the response is text
# Here unlikely if the reponse content is of type **iso-8859-1** we will have to override the response encoding
url = 'some_page_url'

response = get(url)
# override encoding by real educated guess as provided by chardet
r.encoding = r.apparent_encoding

with open('output', 'w', encoding='utf-8') as file:
    file.write(response.content)

Sometimes that (copying the pub ssh key to github/bitbucket) is not enough, particularly with Bitbucket. You also may need to check if your ssh is using the identity you expect rather than messing up with git remote

Check if the agent is using the same identity you pasted on github/bitbucket with ssh-add -l. If missing add it with

ssh-add ~/.ssh/id_rsa_my_git_identity

Try npm cache clean --force if it doesn't work then manually delete %appdata%\npm-cache folder.

It worked for me.

I've written following code which cleans object from proxies (if they are not already initialized)

public class PersistenceUtils {

    private static void cleanFromProxies(Object value, List<Object> handledObjects) {
        if ((value != null) && (!isProxy(value)) && !containsTotallyEqual(handledObjects, value)) {
            handledObjects.add(value);
            if (value instanceof Iterable) {
                for (Object item : (Iterable<?>) value) {
                    cleanFromProxies(item, handledObjects);
                }
            } else if (value.getClass().isArray()) {
                for (Object item : (Object[]) value) {
                    cleanFromProxies(item, handledObjects);
                }
            }
            BeanInfo beanInfo = null;
            try {
                beanInfo = Introspector.getBeanInfo(value.getClass());
            } catch (IntrospectionException e) {
                // LOGGER.warn(e.getMessage(), e);
            }
            if (beanInfo != null) {
                for (PropertyDescriptor property : beanInfo.getPropertyDescriptors()) {
                    try {
                        if ((property.getWriteMethod() != null) && (property.getReadMethod() != null)) {
                            Object fieldValue = property.getReadMethod().invoke(value);
                            if (isProxy(fieldValue)) {
                                fieldValue = unproxyObject(fieldValue);
                                property.getWriteMethod().invoke(value, fieldValue);
                            }
                            cleanFromProxies(fieldValue, handledObjects);
                        }
                    } catch (Exception e) {
                        // LOGGER.warn(e.getMessage(), e);
                    }
                }
            }
        }
    }

    public static <T> T cleanFromProxies(T value) {
        T result = unproxyObject(value);
        cleanFromProxies(result, new ArrayList<Object>());
        return result;
    }

    private static boolean containsTotallyEqual(Collection<?> collection, Object value) {
        if (CollectionUtils.isEmpty(collection)) {
            return false;
        }
        for (Object object : collection) {
            if (object == value) {
                return true;
            }
        }
        return false;
    }

    public static boolean isProxy(Object value) {
        if (value == null) {
            return false;
        }
        if ((value instanceof HibernateProxy) || (value instanceof PersistentCollection)) {
            return true;
        }
        return false;
    }

    private static Object unproxyHibernateProxy(HibernateProxy hibernateProxy) {
        Object result = hibernateProxy.writeReplace();
        if (!(result instanceof SerializableProxy)) {
            return result;
        }
        return null;
    }

    @SuppressWarnings("unchecked")
    private static <T> T unproxyObject(T object) {
        if (isProxy(object)) {
            if (object instanceof PersistentCollection) {
                PersistentCollection persistentCollection = (PersistentCollection) object;
                return (T) unproxyPersistentCollection(persistentCollection);
            } else if (object instanceof HibernateProxy) {
                HibernateProxy hibernateProxy = (HibernateProxy) object;
                return (T) unproxyHibernateProxy(hibernateProxy);

    private static Object unproxyPersistentCollection(PersistentCollection persistentCollection) {
        if (persistentCollection instanceof PersistentSet) {
            return unproxyPersistentSet((Map<?, ?>) persistentCollection.getStoredSnapshot());
        }
        return persistentCollection.getStoredSnapshot();
    }

    private static <T> Set<T> unproxyPersistentSet(Map<T, ?> persistenceSet) {
        return new LinkedHashSet<T>(persistenceSet.keySet());
    }

}

I use this function over result of my RPC services (via aspects) and it cleans recursively all result objects from proxies (if they are not initialized).

You will want to use a CONVERT() statement.

Try the following;

SELECT CONVERT(VARCHAR(10), SA.[RequestStartDate], 103) as 'Service Start Date', CONVERT(VARCHAR(10), SA.[RequestEndDate], 103) as 'Service End Date', FROM (......) SA WHERE.....

See MSDN Cast and Convert for more information.

I did not find a CRTP implementation among the answers, so here it is:

template<typename HeirT>
class Singleton
{
public:
    Singleton() = delete;

    Singleton(const Singleton &) = delete;

    Singleton &operator=(const Singleton &) = delete;

    static HeirT &instance()
    {
        static HeirT instance;
        return instance;
    }
};

To use just inherit your class from this, like: class Test : public Singleton<Test>

Because of one day is 24 * 60 * 60 * 1000 ms, the midnight of this day can be calculate as...

long now = System.currentTimeMillis();
long delta = now % 24 * 60 * 60 * 1000;
long midnight = now - delta;
Date midnightDate = new Date(midnight);`

I modified Neutrino's solution to make the xaml look less verbose when specifying the value:

Sorry for no pictures of the rendered xaml, just imagine a [=] hamburger button that you click and it turns into [<-] a back button and also toggles the visibility of a Grid.

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

...

<Grid>
    <Button x:Name="optionsButton">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Visible" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Hamburger Width="10" Height="10" />
    </Button>

    <Button x:Name="optionsBackButton" Visibility="Collapsed">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Collapsed" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Back Width="12" Height="11" />
    </Button>
</Grid>

...

<Grid Grid.RowSpan="2" x:Name="optionsPanel" Visibility="Collapsed">

</Grid>

You can also specify values this way like in Neutrino's solution:

<Button x:Name="optionsButton">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <local:SetterAction PropertyName="Visibility" Value="{x:Static Visibility.Collapsed}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="{x:Static Visibility.Visible}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="{x:Static Visibility.Visible}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

    <glyphs:Hamburger Width="10" Height="10" />
</Button>

Just got this, we can achieve it using onpaste:"return false", thanks to: http://sumtips.com/2011/11/prevent-copy-cut-paste-text-field.html

We have various other options available as listed below.

<input type="text" onselectstart="return false" onpaste="return false;" onCopy="return false" onCut="return false" onDrag="return false" onDrop="return false" autocomplete=off/><br>

I kept getting errors from openssl when using StoBor's command:

For some reason, only this style of command would work for my JKS file

keytool -importkeystore -srckeystore foo.jks \
   -destkeystore foo.p12 \
   -srcstoretype jks \
   -srcalias mykey \
   -deststoretype pkcs12 \
   -destkeypass DUMMY123

The key was setting destkeypass, the value of the argument did not matter.

I had to do a :

git checkout -b master

as git said that it doesn't exists, because it's been wipe with the

git -D master

Convert the string to an InputStream and pass it to DocumentBuilder

final InputStream stream = new ByteArrayInputStream(string.getBytes(StandardCharsets.UTF_8));
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
builder.parse(stream);

EDIT
In response to bendin's comment regarding encoding, see shsteimer's answer to this question.

Although this doesn't cover sets, it is a good explanation of dicts and lists:

Lists are what they seem - a list of values. Each one of them is numbered, starting from zero - the first one is numbered zero, the second 1, the third 2, etc. You can remove values from the list, and add new values to the end. Example: Your many cats' names.

Dictionaries are similar to what their name suggests - a dictionary. In a dictionary, you have an 'index' of words, and for each of them a definition. In python, the word is called a 'key', and the definition a 'value'. The values in a dictionary aren't numbered - tare similar to what their name suggests - a dictionary. In a dictionary, you have an 'index' of words, and for each of them a definition. The values in a dictionary aren't numbered - they aren't in any specific order, either - the key does the same thing. You can add, remove, and modify the values in dictionaries. Example: telephone book.

There is U+1F50D LEFT-POINTING MAGNIFYING GLASS () and U+1F50E RIGHT-POINTING MAGNIFYING GLASS ().

You should use (in HTML) 🔍 or 🔎

They are, however not supported by many fonts (fileformat.info only lists a few fonts as supporting the Codepoint with a proper glyph).

Also note that they are outside of the BMP, so some Unicode-capable software might have problems rendering them, even if they have fonts that support them.

Generally Unicode Glyphs can be searched using a site such as fileformat.info. This searches "only" in the names and properties of the Unicode glyphs, but they usually contain enough metadata to allow for good search results (for this answer I searched for "glass" and browsed the resulting list, for example)

A comprehansive comparison between diffreent formats made by me in this post- https://maxondev.com/serialization-performance-comparison-c-net-formats-frameworks-xmldatacontractserializer-xmlserializer-binaryformatter-json-newtonsoft-servicestack-text/

Just one sample from the post-

return await Task.FromResult(new MyClass());

In your View try like this

  <img src= "@Url.Content(Model.ImagePath)" alt="Image" />

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

For a realistic approach that emulates the most human behavior, you may want to add a referer in your curl options. You may also want to add a follow_location to your curl options. Trust me, whoever said that cURLING Google results is impossible, is a complete dolt and should throw his/her computer against the wall in hopes of never returning to the internetz again. Everything that you can do "IRL" with your own browser can all be emulated using PHP cURL or libCURL in Python. You just need to do more cURLS to get buff. Then you will see what I mean. :)

  $url = "http://www.google.com/search?q=".$strSearch."&hl=en&start=0&sa=N";
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.example.com/1');
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_VERBOSE, 0);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
  curl_setopt($ch, CURLOPT_URL, urlencode($url));
  $response = curl_exec($ch);
  curl_close($ch);

UPDATE: As of Bootstrap 3.0, the input-* classes described below for setting the width of input elements were removed. Instead use the col-* classes to set the width of input elements. Examples are provided in the documentation.

In Bootstrap 2.3, you'd use the input classes for setting the width.

<textarea class="input-mini"></textarea>
<textarea class="input-small"></textarea>
<textarea class="input-medium"></textarea>
<textarea class="input-large"></textarea>
<textarea class="input-xlarge"></textarea>
<textarea class="input-xxlarge"></textarea>?
<textarea class="input-block-level"></textarea>?

Do a find for "Control sizing" for examples in the documentation.

But for height I think you'd still use the rows attribute.

You should use DateTime.TryParseExcact if you know the format, or if not and want to use the system settings DateTime.TryParse. And to print the date,DateTime.ToString with the right format in the argument. To get the year, month or day you have DateTime.Year, DateTime.Month or DateTime.Day.

See DateTime Structures in MSDN for additional references.

That is the class name and System.identityHashCode() separated by the '@' character. What the identity hash code represents is implementation-specific. It often is the initial memory address of the object, but the object can be moved in memory by the VM over time. So (briefly) you can't rely on it being anything.

Getting the memory addresses of variables is meaningless within Java, since the JVM is at liberty to implement objects and move them as it seems fit (your objects may/will move around during garbage collection etc.)

Integer.toBinaryString() will give you an integer in binary form.

Make sure you don't have any syntax errors in your Dockerfile as this can cause this error as well. A correct example is:

RUN apt-get update \
    && apt-get -y install curl \
    another-package

It was a combination of fixing a syntax error and adding apt-get update that solved the problem for me.

you'll want to use && to see that it is not equal to "AM" AND not equal to "PM"

if(!TimeOfDayStringQ.equals("AM") && !TimeOfDayStringQ.equals("PM")) {
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to be clear you can also do

if(!(TimeOfDayStringQ.equals("AM") || TimeOfDayStringQ.equals("PM"))){
    System.out.println("Sorry, incorrect input.");
    System.exit(1);
}

to have the not (one or the other) phrase in the code (remember the (silent) brackets)

I couldn't figure out how to pass args and also the :environment until I worked this out:

namespace :db do
  desc 'Export product data'
  task :export, [:file_token, :file_path] => :environment do |t, args|
    args.with_defaults(:file_token => "products", :file_path => "./lib/data/")

       #do stuff [...]

  end
end

And then I call like this:

rake db:export['foo, /tmp/']

In answer to the question in how to write to a file in PHP you can use the following as an example:

    $fp = fopen ($filename, "a"); # a = append to the file. w = write to the file (create new if doesn't exist)
    if ($fp) {
        fwrite ($fp, $text); //$text is what you are writing to the file
        fclose ($fp);
        $writeSuccess = "Yes";
        #echo ("File written");
    }
    else {
    $writeSuccess = "No";
    #echo ("File was not written");
    }

Give this a try. It uses pre rather than nowrap as I would assume you would want this to run similarly to <pre> but either will work just fine:

div {
    border: 1px solid black;
    max-width: 70px;
    white-space:pre;
}

http://jsfiddle.net/NXchy/11/

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

You need to find the position of the first /, and then calculate the portion you want:

string url = "www.example.com/aaa/bbb.jpg";
int Idx = url.IndexOf("/");
string yourValue = url.Substring(Idx + 1, url.Length - Idx - 4);

Although the answers above seems correct, just a simple explanation to give you an idea of how it works.

Suppose that your column is set to be DECIMAL(13,4). This means that the column will have a total size of 13 digits where 4 of these will be used for precision representation.

So, in summary, for that column you would have a max value of: 999999999.9999

Is the first line in your script:

#!/bin/bash

or

#!/bin/sh

the sh shell produces this error messages, not bash

React uses event delegation with a single event listener on document for events that bubble, like 'click' in this example, which means stopping propagation is not possible; the real event has already propagated by the time you interact with it in React. stopPropagation on React's synthetic event is possible because React handles propagation of synthetic events internally.

stopPropagation: function(e){
    e.stopPropagation();
    e.nativeEvent.stopImmediatePropagation();
}

See "Is there a way to define variables of two types in for loop?" for another way involving nesting multiple for loops. The advantage of the other way over Georg's "struct trick" is that it (1) allows you to have a mixture of static and non-static local variables and (2) it allows you to have non-copyable variables. The downside is that it is far less readable and may be less efficient.

There are two commands which will work in this situation,

root>git reset --hard HEAD~1

root>git push -f

For more git commands refer this page

based on accepted answer

$output = some_function();
  echo $output;

if it results array then use json_encode it will result json array which is supportable by javascript

$output = some_function();
  echo json_encode($output);

If someone wants to stop execution after you echo some result use exit method of php. It will work like return keyword

$output = some_function();
  echo $output;
exit;

Use the show_source(); function of PHP. Check for more details in show_source. This is a better method I guess.

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

another simple approach with modern built-in stuff like PercentRelativeLayout is now available for new users who hit this problem. thanks to android team for release this item.

<android.support.percent.PercentRelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true"
app:layout_widthPercent="50%">

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:id="@+id/picture"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

    <TextView
        android:id="@+id/text"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="#55000000"
        android:paddingBottom="15dp"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:paddingTop="15dp"
        android:textColor="@android:color/white" />

</FrameLayout>

and for better performance you can use some stuff like picasso image loader which help you to fill whole width of every image parents. for example in your adapter you should use this:

int width= context.getResources().getDisplayMetrics().widthPixels;
    com.squareup.picasso.Picasso
            .with(context)
            .load("some url")
            .centerCrop().resize(width/2,width/2)
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(item.drawableId);

now you dont need CustomImageView Class anymore.

P.S i recommend to use ImageView in place of Type Int in class Item.

hope this help..

Since I prefer to list required arguments before optional, I hack around it via:

    parser = argparse.ArgumentParser()
    parser._action_groups.pop()
    required = parser.add_argument_group('required arguments')
    optional = parser.add_argument_group('optional arguments')
    required.add_argument('--required_arg', required=True)
    optional.add_argument('--optional_arg')
    return parser.parse_args()

and this outputs:

usage: main.py [-h] [--required_arg REQUIRED_ARG]
               [--optional_arg OPTIONAL_ARG]

required arguments:
  --required_arg REQUIRED_ARG

optional arguments:
  --optional_arg OPTIONAL_ARG

I can live without 'help' showing up in the optional arguments group.

I've tested this using the following powershell script and using (,) between the addresses. It worked for me!

$EmailFrom = "<[email protected]>";
$EmailPassword = "<password>";
$EmailTo = "<[email protected]>,<[email protected]>";
$SMTPServer = "<smtp.server.com>";
$SMTPPort = <port>;
$SMTPClient = New-Object Net.Mail.SmtpClient($SmtpServer,$SMTPPort);
$SMTPClient.EnableSsl = $true;
$SMTPClient.Credentials = New-Object System.Net.NetworkCredential($EmailFrom, $EmailPassword);
$Subject = "Notification from XYZ";
$Body = "this is a notification from XYZ Notifications..";
$SMTPClient.Send($EmailFrom, $EmailTo, $Subject, $Body);

SshClient cSSH = new SshClient("192.168.10.144", 22, "root", "pacaritambo");
cSSH.Connect();
SshCommand x = cSSH.RunCommand("exec \"/var/lib/asterisk/bin/retrieve_conf\"");
cSSH.Disconnect();
cSSH.Dispose();

//using SSH.Net

There is a better answer to this problem, though I could just break this down step-by-step.

You will need to fetch and checkout the latest upstream changes like so, e.g.:

git fetch upstream
git checkout upstream/master -b revert/john/foo_and_bar

Taking a look at the commit log, you should find something similar to this:

commit b76a5f1f5d3b323679e466a1a1d5f93c8828b269
Merge: 9271e6e a507888
Author: Tim Tom <[email protected]>
Date:   Mon Apr 29 06:12:38 2013 -0700

    Merge pull request #123 from john/foo_and_bar

    Add foo and bar

commit a507888e9fcc9e08b658c0b25414d1aeb1eef45e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 12:13:29 2013 +0000

    Add bar

commit 470ee0f407198057d5cb1d6427bb8371eab6157e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 10:29:10 2013 +0000

    Add foo

Now you want to revert the entire pull request with the ability to unrevert later. To do so, you will need to take the ID of the merge commit.

In the above example the merge commit is the top one where it says "Merged pull request #123...".

Do this to revert the both changes ("Add bar" and "Add foo") and you will end up with in one commit reverting the entire pull request which you can unrevert later on and keep the history of changes clean:

git revert -m 1 b76a5f1f5d3b323679e466a1a1d5f93c8828b269

Try reducing the range of the for loop to range(len(a)-1):

a = [0,1,2,3]
b = []

for i in range(len(a)-1):
    b.append(a[i]+a[i+1])

print(b)

This can also be written as a list comprehension:

b = [a[i] + a[i+1] for i in range(len(a)-1)]
print(b)

typedef defines a new data type. So you can have:

typedef char* my_string;
typedef struct{
  int member1;
  int member2;
} my_struct;

So now you can declare variables with these new data types

my_string s;
my_struct x;

s = "welcome";
x.member1 = 10;

For enum, things are a bit different - consider the following examples:

enum Ranks {FIRST, SECOND};
int main()
{
   int data = 20;
   if (data == FIRST)
   {
      //do something
   }
}

using typedef enum creates an alias for a type:

typedef enum Ranks {FIRST, SECOND} Order;
int main()
{
   Order data = (Order)20;  // Must cast to defined type to prevent error

   if (data == FIRST)
   {
      //do something
   }
}

select tableA.id from tableA left outer join tableB on (tableA.id = tableB.id)
where tableB.id is null
order by tableA.id desc 

If your db knows how to do index intersections, this will only touch the primary key index

os.system('command') returns a 16 bit number, which first 8 bits from left(lsb) talks about signal used by os to close the command, Next 8 bits talks about return code of command.

Refer my answer for more detail in What is the return value of os.system() in Python?

Powershell

For powershell, use #:

PS C:\> echo foo # This is a comment
foo

Move doSomething definition outside of its class declaration and after B and also make add accessible to A by public-ing it or friend-ing it.

class B;

class A
{
    void doSomething(B * b);
};

class B
{
public:
    void add() {}
};

void A::doSomething(B * b)
{
    b->add();
}

After spending too much time on this issue and trying out all different answers, here is what found:

• The accepted answer by @thewaywewere is no longer applicable. I think this was applicable when opencv-python module still wasn't available.

• This is indeed a bug in Anaconda 4.2 because they forgot to ship python3.dll. They have fixed this in next releases but unfortunately 4.2 is the last release with Python 3.5 as default. If you are stuck with Python 3.5 (for example VS2015 is only aware of versions up to 3.5) then you must manually download python3.dll as described in answer by @Ramesh-X.

• If you can move on to Python 3.6 (which at present bit difficult if you are using OpenCV and VS2015) then just install latest Anaconda version and you don't have to deal with any of these.

You can only return one value, but it can be an object that has multiple fields - ie a "value object". Eg

public class MyResult {
    int returnCode;
    String errorMessage;
    // etc
}

public MyResult someMethod() {
    // impl here
}

Try Like this:

<?php

    namespace App\Http\Controllers;

    use Illuminate\Http\Request;

    use DB;

    class UserController extends Controller
    {

    function  index(){

    $users = DB::table('users')->get();

    foreach ($users as $user)
    {
        var_dump($user->name);
    }

    }
  }

?>

try tomcat tomcat as the default username and password (tomcat 7)

Try this:

Get-ChildItem -Path V:\Myfolder -Filter CopyForbuild.bat -Recurse | Where-Object { $_.Attributes -ne "Directory"}

Math.floor(Math.random() * (limit+1))

Math.random() generates a floating point number between 0 and 1, Math.floor() rounds it down to an integer.

By multiplying it by a number, you effectively make the range 0..number-1. If you wish to generate it in range from num1 to num2, do:

Math.floor(Math.random() * (num2-num1 + 1) + num1)

To generate more numbers, just use a for loop and put results into an array or write them into the document directly.

Only the shortcut syntax worked for me *ngIf.

(I think it's the later versions that use this syntax if I'm not mistaken)

<div *ngIf="haystack.indexOf('needle') > -1">
</div>

or

<div *ngIf="haystack.includes('needle')">
</div>

These two together worked for me:

android:scrollbarFadeDuration="0"
android:scrollbarAlwaysDrawVerticalTrack="true"

System read-only variable %CD% keeps the path of the caller of the batch, not the batch file location.

You can get the name of the batch script itself as typed by the user with %0 (e.g. scripts\mybatch.bat). Parameter extensions can be applied to this so %~dp0 will return the Drive and Path to the batch script (e.g. W:\scripts\) and %~f0 will return the full pathname (e.g. W:\scripts\mybatch.cmd).

You can refer to other files in the same folder as the batch script by using this syntax:

CALL %0\..\SecondBatch.cmd

This can even be used in a subroutine, Echo %0 will give the call label but, echo "%~nx0" will give you the filename of the batch script.

When the %0 variable is expanded, the result is enclosed in quotation marks.

More on batch parameters.

You can get it like

[ x[0] for x in a]

which will return a list of the first element of each list in a
