Solved it by removing the "Excluded" in the module setting (right click on project, "Open module settings").

/<\/?[^>]*>/.test(str) Only detect whether it contains html tags, may be a xml

MarvinS.-

Try:

$.ajax({  
        url: uri+'?js',  
        success: function(data) {  
                var imgAttr = $("img", data).attr('src'); 
                var htmlCode = $(data).html();
                $('#imgSrc').html(imgAttr);
                $('#fullHtmlOutput').html(htmlCode);
        }  
    });

This should load the whole html block from data into #fullHtmlOutput and the src of the image into #imgSrc.

In case you're using git, use the right email address you used for github registration and then your computer name. this worked for me.

All the metadata about the columns in Oracle Database is accessible using one of the following views.

user_tab_cols; -- For all tables owned by the user

all_tab_cols ; -- For all tables accessible to the user

dba_tab_cols; -- For all tables in the Database.

So, if you are looking for a column like ADD_TMS in SCOTT.EMP Table and add the column only if it does not exist, the PL/SQL Code would be along these lines..

DECLARE
  v_column_exists number := 0;  
BEGIN
  Select count(*) into v_column_exists
    from user_tab_cols
    where upper(column_name) = 'ADD_TMS'
      and upper(table_name) = 'EMP';
      --and owner = 'SCOTT --*might be required if you are using all/dba views

  if (v_column_exists = 0) then
      execute immediate 'alter table emp add (ADD_TMS date)';
  end if;
end;
/

If you are planning to run this as a script (not part of a procedure), the easiest way would be to include the alter command in the script and see the errors at the end of the script, assuming you have no Begin-End for the script..

If you have file1.sql

alter table t1 add col1 date;
alter table t1 add col2 date;
alter table t1 add col3 date;

And col2 is present,when the script is run, the other two columns would be added to the table and the log would show the error saying "col2" already exists, so you should be ok.

This may help you...

When I went to Google fonts all they gave me were true type font files .ttf and didn't explain at all how to use the @font-face to include them into my document. I tried the web font generator from font squirrel too, which just kept running the loading gif and not working... I then found this site -

https://transfonter.org/

I had great success using the following method:

I selected the Add Fonts button, leaving the default options, added all of my .ttf that Google gave me for Open Sans (which was like 10, I chose a lot of options...).

Then I selected the Convert button.

Heres the best part!

They gave me a zip file with all the font format files I selected, .ttf, .woff and .eot. Inside that zip file they had a demo.html file that I just double clicked on and it opened up a web page in my browser showing me example usages of all the different css font options, how to implement them, and what they looked like etc.

@font-face

I still didn't know at this point how to include the fonts into my stylesheet properly using @font-face but then I noticed that this demo.html came with it's own stylesheet in the zip as well. I opened the stylesheet and it showed how to bring in all of the fonts using @font-face so I was able to quickly, and easily, copy paste this into my project -

The demo.html also had it's own inline stylesheet that was interesting to take a look at, though I am familiar with working with font weights and styles once they are included so I didn't need it much. For an example of how to implement a font style onto an html element for reference purposes you could use the following method in a similar case to mine after @font-face has been used properly -

html, body{
    margin: 0;
    font-family: 'Open Sans';
}
.banner h1{
    font-size: 43px;
    font-weight: 700;
}
.banner p{
    font-size: 24px;
    font-weight: 300;
    font-style: italic;
}

I think...

Search partial value:

SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])*key_word([^"])*"';

Search exact word:

SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';

jQuery transit will probably make your life easier if you are dealing with CSS3 animations through jQuery.

EDIT March 2014 (because my advice has constantly been up and down voted since I posted it)

Let me explain why I was initially hinting towards the plugin above:

Updating the DOM on each step (i.e. $.animate ) is not ideal in terms of performance. It works, but will most probably be slower than pure CSS3 transitions or CSS3 animations.

This is mainly because the browser gets a chance to think ahead if you indicate what the transition is going to look like from start to end.

To do so, you can for example create a CSS class for each state of the transition and only use jQuery to toggle the animation state.

This is generally quite neat as you can tweak you animations alongside the rest of your CSS instead of mixing it up with your business logic:

// initial state
.eye {
   -webkit-transform: rotate(45deg);
   -moz-transform: rotate(45deg);
   transform: rotate(45deg);
   // etc.

   // transition settings
   -webkit-transition: -webkit-transform 1s linear 0.2s;
   -moz-transition: -moz-transform 1s linear 0.2s;
   transition: transform 1s linear 0.2s;
   // etc.
}

// open state    
.eye.open {

   transform: rotate(90deg);
}

// Javascript
$('.eye').on('click', function () { $(this).addClass('open'); });

If any of the transform parameters is dynamic you can of course use the style attribute instead:

$('.eye').on('click', function () { 
    $(this).css({ 
        -webkit-transition: '-webkit-transform 1s ease-in',
        -moz-transition: '-moz-transform 1s ease-in',
        // ...

        // note that jQuery will vendor prefix the transform property automatically
        transform: 'rotate(' + (Math.random()*45+45).toFixed(3) + 'deg)'
    }); 
});

A lot more detailed information on CSS3 transitions on MDN.

HOWEVER There are a few other things to keep in mind and all this can get a bit tricky if you have complex animations, chaining etc. and jQuery Transit just does all the tricky bits under the hood:

$('.eye').transit({ rotate: '90deg'}); // easy huh ?

When using CMAKE and find_package, make sure it is :

find_package(Boost COMPONENTS system ...)

and not

find_package(boost COMPONENTS system ...)

Some people may have lost hours for that ...

These are not command line args. Run psql. Manage to log into database (so pass the hostname, port, user and database if needed). And then write it in the psql program.

Example (below are two commands, write the first one, press enter, wait for psql to login, write the second):

psql -h host -p 5900 -U username database
\pset format aligned

Here is an example straight from PHP.net

$a = array(
    "one" => 1,
    "two" => 2,
    "three" => 3,
    "seventeen" => 17
);

foreach ($a as $k => $v) {
    echo "\$a[$k] => $v.\n";
}

in the foreach you can do a comparison of each key to something that you are looking for

@Travis solution is right, but it loses milliseconds when a Date is generated. I have added a line to include the milliseconds into the date:

If you don't need this precision, use the Travis solution because it will be faster.

extension Date {

    func toMillis() -> Int64! {
        return Int64(self.timeIntervalSince1970 * 1000)
    }

    init(millis: Int64) {
        self = Date(timeIntervalSince1970: TimeInterval(millis / 1000))
        self.addTimeInterval(TimeInterval(Double(millis % 1000) / 1000 ))
    }

}

It's been many functions, macros and objects since I posted this question. The way I handled it, which is mentioned in one of the answers here, is by creating a string function that handles the errors that get generate by the vlookup function, and returns either nothing or the vlookup result if any.

Function fsVlookup(ByVal pSearch As Range, ByVal pMatrix As Range, ByVal pMatColNum As Integer) As String
    Dim s As String
    On Error Resume Next
    s = Application.WorksheetFunction.VLookup(pSearch, pMatrix, pMatColNum, False)
    If IsError(s) Then
        fsVlookup = ""
    Else
        fsVlookup = s
    End If
End Function

One could argue about the position of the error handling or by shortening this code, but it works in all cases for me, and as they say, "if it ain't broke, don't try and fix it".

In [6]: x = -2
In [7]: x
Out[7]: -2

In [8]: abs(x)
Out[8]: 2

Actually abs will return the absolute value of any number. Absolute value is always a non-negative number.

Here is the simplest way to do this

static void Main(string[] args)
{
    Task t = MainAsync(args);
    t.Wait();
}

static async Task MainAsync(string[] args)
{
    await ...
}

After a full day working on this feature finally able to get the right answer.

First, create the following classes:

import android.util.Log;
import android.view.MotionEvent;
import android.view.View;

/**
 * Created by hoshyar on 1/19/17.
 */

public class SwipeDetector implements View.OnTouchListener {

    public static enum Action {
        LR, // Left to Right
        RL, // Right to Left
        TB, // Top to bottom
        BT, // Bottom to Top
        None // when no action was detected
    }

    private static final String logTag = "Swipe";
    private static final int MIN_DISTANCE = 100;
    private float downX, downY, upX, upY;
    private Action mSwipeDetected = Action.None;

    public boolean swipeDetected() {
        return mSwipeDetected != Action.None;
    }

    public Action getAction() {
        return mSwipeDetected;
    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                downX = event.getX();
                downY = event.getY();
                mSwipeDetected = Action.None;
                return false;

            case MotionEvent.ACTION_MOVE:
                upX = event.getX();
                upY = event.getY();

                float deltaX = downX - upX;
                float deltaY = downY - upY;
                Log.i(logTag,String.valueOf(deltaX));
                Log.i(logTag,String.valueOf(deltaX));

                if (deltaY>0 && deltaY<10 && deltaX<0 || deltaY==0 && deltaX>-15 && deltaX<0){
                    Log.i(logTag,"to right");
                }if (deltaY>=0 && deltaY<10 && deltaX>0 || deltaY<0 && deltaX>15 && deltaX<40){
                Log.i(logTag,"to left");
            }





                if (Math.abs(deltaX) > MIN_DISTANCE) {
                    // left or right
                    if (deltaX < 0) {
                        mSwipeDetected = Action.LR;
                        return false;
                    }
                    if (deltaX > 0) {


                        mSwipeDetected = Action.RL;
                        return false;
                    }
                } else if (Math.abs(deltaY) > MIN_DISTANCE) {


                    if (deltaY < 0) {
                        Log.i(logTag,"to bottom");
                        mSwipeDetected = Action.TB;
                        return false;
                    }
                    if (deltaY > 0) {
                        Log.i(logTag,"to up");
                        mSwipeDetected = Action.BT;
                        return false;
                    }
                }
                return true;
        }
        return false;
    }
}

Finally on the object that you want to apply. My example:

SwipeDetector swipeDetector = new SwipeDetector();
listView.setOnTouchListener(swipeDetector);

Good luck .

SELECT IF((
     SELECT count(*) FROM gdata_calendars 
     WHERE `group` =  ? AND id = ?)
,1,0);

If you are working on XAMPP then you can fix the MySQL Server has gone away issue with following changes..

open your my.ini file my.ini location is (D:\xampp\mysql\bin\my.ini)

change the following variable values

max_allowed_packet = 64M
innodb_lock_wait_timeout = 500

As per §2.4 of the XML 1.0 spec, you should be able to use &.

I tried & but this isn't allowed.

Are you sure it isn't a different issue? XML explicitly defines this as the way to escape ampersands.

This was pretty well answered over here: How to make a YouTube embedded video a full page width one?

If you add '?rel=0&autoplay=1' to the end of the url in the embed code (like this)

<iframe id="video" src="//www.youtube.com/embed/5iiPC-VGFLU?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>

of the video it should play on load. Here's a demo over at jsfiddle.

The above techniques are good if you want to avoid a library, but depending if you would be alright with a library, I would suggest checking out Chance for generating random stuff in JavaScript.

Specifically to solve your question, using Chance it's as easy as:

// One line!_x000D_
var uniques = chance.unique(chance.natural, 8, {min: 1, max: 100});_x000D_
_x000D_
// Print it out to the document for this snippet so we can see it in action_x000D_
document.write(JSON.stringify(uniques));

<script src="http://chancejs.com/chance.min.js"></script>

Please follow below step to do some processing after Application Context get loaded i.e application is ready to serve.

1. Create below annotation i.e

   @Retention(RetentionPolicy.RUNTIME) @Target(value= {ElementType.METHOD, ElementType.TYPE}) public @interface AfterApplicationReady {}

2.Create Below Class which is a listener which get call on application ready state.

            LOGGER.warn("Exception occured : ", e);
        }
    }
}

Finally when you start your Spring application just before log stating application started your listener will be called.

This page has the HOWTO:

http://www.golesny.de/p/code/javagetpid

On Windows:

Runtime.exec(..)

Returns an instance of "java.lang.Win32Process") OR "java.lang.ProcessImpl"

Both have a private field "handle".

This is an OS handle for the process. You will have to use this + Win32 API to query PID. That page has details on how to do that.

Yes there is one and it is inside the SQLServer management studio. Unlike the previous versions I think. Follow these simple steps.

1)Right click on a database in the Object explorer 2)Selected New Query from the popup menu 3)Query Analyzer will be opened.

Enjoy work.

I was having same problem where I wanted to run my react app on port 3000 and storybook on port 6006 both in the same containers.

I tried to start both as entrypoint commands from Dockerfile as well as using docker-compose command option.

After spending time on this, decided to separate these services into separate containers and it worked like charm

To run a non-executable sh script, use:

sh myscript

To run a non-executable bash script, use:

bash myscript

To start an executable (which is any file with executable permission); you just specify it by its path:

/foo/bar
/bin/bar
./bar

To make a script executable, give it the necessary permission:

chmod +x bar
./bar

When a file is executable, the kernel is responsible for figuring out how to execte it. For non-binaries, this is done by looking at the first line of the file. It should contain a hashbang:

#! /usr/bin/env bash

The hashbang tells the kernel what program to run (in this case the command /usr/bin/env is ran with the argument bash). Then, the script is passed to the program (as second argument) along with all the arguments you gave the script as subsequent arguments.

That means every script that is executable should have a hashbang. If it doesn't, you're not telling the kernel what it is, and therefore the kernel doesn't know what program to use to interprete it. It could be bash, perl, python, sh, or something else. (In reality, the kernel will often use the user's default shell to interprete the file, which is very dangerous because it might not be the right interpreter at all or it might be able to parse some of it but with subtle behavioural differences such as is the case between sh and bash).

A note on /usr/bin/env

Most commonly, you'll see hash bangs like so:

#!/bin/bash

The result is that the kernel will run the program /bin/bash to interpret the script. Unfortunately, bash is not always shipped by default, and it is not always available in /bin. While on Linux machines it usually is, there are a range of other POSIX machines where bash ships in various locations, such as /usr/xpg/bin/bash or /usr/local/bin/bash.

To write a portable bash script, we can therefore not rely on hard-coding the location of the bash program. POSIX already has a mechanism for dealing with that: PATH. The idea is that you install your programs in one of the directories that are in PATH and the system should be able to find your program when you want to run it by name.

Sadly, you cannot just do this:

#!bash

The kernel won't (some might) do a PATH search for you. There is a program that can do a PATH search for you, though, it's called env. Luckily, nearly all systems have an env program installed in /usr/bin. So we start env using a hardcoded path, which then does a PATH search for bash and runs it so that it can interpret your script:

#!/usr/bin/env bash

This approach has one downside: According to POSIX, the hashbang can have one argument. In this case, we use bash as the argument to the env program. That means we have no space left to pass arguments to bash. So there's no way to convert something like #!/bin/bash -exu to this scheme. You'll have to put set -exu after the hashbang instead.

This approach also has another advantage: Some systems may ship with a /bin/bash, but the user may not like it, may find it's buggy or outdated, and may have installed his own bash somewhere else. This is often the case on OS X (Macs) where Apple ships an outdated /bin/bash and users install an up-to-date /usr/local/bin/bash using something like Homebrew. When you use the env approach which does a PATH search, you take the user's preference into account and use his preferred bash over the one his system shipped with.

Also important is height of the map container. If to small infoWindow always will be on 80px height. Otherwise maxWidth and #innerDiv fix works like a charm.

The basic difference is:

int i = Console.Read();
Console.WriteLine(i);

paste above code and give input 'c', and the output will be 99. That is Console.Read give int value but that value will be the ASCII value of that..

On the other side..

string s = Console.ReadLine();
Console.WriteLine(s);

It gives the string as it is given in the input stream.

I think you could use istream .read() function. You can just loop with reasonable chunk size and read directly to memory buffer, then append it to some sort of arbitrary memory container (such as std::vector). I could write an example, but I doubt you want a complete solution; please let me know if you shall need any additional information.

Solution for the code you posted:

.center{
    position:absolute;
    width:780px;
    height:650px;
    left:50%;
    top:50%;
    margin-left:-390px;
    margin-top:-325px;
}

How this works?

Example: http://jsfiddle.net/953Yj/

<div class="center">
    Lorem ipsum
</div>

.center{
    position:absolute;
    height: X px;
    width: Y px;
    left:50%;
    top:50%;
    margin-top:- X/2 px;
    margin-left:- Y/2 px;
}

• X would your your height.
• Y would be your width.

To position the div vertically and horizontally, divide X and Y by 2.

You need to link the with the -lm linker option

You need to compile as

gcc test.c  -o test -lm

gcc (Not g++) historically would not by default include the mathematical functions while linking. It has also been separated from libc onto a separate library libm. To link with these functions you have to advise the linker to include the library -l linker option followed by the library name m thus -lm.

If you are using eclipse try:

Window > Preferences > Android > Launch

Default emulator options: -dns-server 8.8.8.8,8.8.4.4

If you're like me and no so into C++ purism, here's an old skool hybrid. There's some advantage when strings are more than a handful of characters, as most memcmp implementations compare machine words when possible.

You need to be in control of the character set. For example, if this approach is used with utf-8 or wchar type, there's some disadvantage as it won't support character mapping - e.g., when two or more characters are logically identical.

bool starts_with(std::string const & value, std::string const & prefix)
{
    size_t valueSize = value.size();
    size_t prefixSize = prefix.size();

    if (prefixSize > valueSize)
    {
        return false;
    }

    return memcmp(value.data(), prefix.data(), prefixSize) == 0;
}


bool ends_with(std::string const & value, std::string const & suffix)
{
    size_t valueSize = value.size();
    size_t suffixSize = suffix.size();

    if (suffixSize > valueSize)
    {
        return false;
    }

    const char * valuePtr = value.data() + valueSize - suffixSize;

    return memcmp(valuePtr, suffix.data(), suffixSize) == 0;
}

You should have a look at numpy if you do matrix manipulation. This is a module mainly written in C, which will be much faster than programming in pure python. Here is an example of how to invert a matrix, and do other matrix manipulation.

from numpy import matrix
from numpy import linalg
A = matrix( [[1,2,3],[11,12,13],[21,22,23]]) # Creates a matrix.
x = matrix( [[1],[2],[3]] )                  # Creates a matrix (like a column vector).
y = matrix( [[1,2,3]] )                      # Creates a matrix (like a row vector).
print A.T                                    # Transpose of A.
print A*x                                    # Matrix multiplication of A and x.
print A.I                                    # Inverse of A.
print linalg.solve(A, x)     # Solve the linear equation system.

You can also have a look at the array module, which is a much more efficient implementation of lists when you have to deal with only one data type.

From the sample app, check out this variation. https://github.com/mpospese/MPFoldTransition/

Always check the standard libraries first.

import java.util.Arrays;

Then try:

System.out.println(Arrays.toString(array));

or if your array contains other arrays as elements:

System.out.println(Arrays.deepToString(array));

If you already have a dataframe, this is the fastest way:

In [1]: columns = ["col{}".format(i) for i in range(10)]
In [2]: orig_df = pd.DataFrame(np.ones((10, 10)), columns=columns)
In [3]: %timeit d = pd.DataFrame(np.zeros_like(orig_df), index=orig_df.index, columns=orig_df.columns)
10000 loops, best of 3: 60.2 µs per loop

Compare to:

In [4]: %timeit d = pd.DataFrame(0, index = np.arange(10), columns=columns)
10000 loops, best of 3: 110 µs per loop

In [5]: temp = np.zeros((10, 10))
In [6]: %timeit d = pd.DataFrame(temp, columns=columns)
10000 loops, best of 3: 95.7 µs per loop

Roll your own:

function Count(text) 
{
    //asp.net textarea maxlength doesnt work; do it by hand
    var maxlength = 2000; //set your value here (or add a parm and pass it in)
    var object = document.getElementById(text.id)  //get your object
    if (object.value.length > maxlength) 
    {
        object.focus(); //set focus to prevent jumping
        object.value = text.value.substring(0, maxlength); //truncate the value
        object.scrollTop = object.scrollHeight; //scroll to the end to prevent jumping
        return false;
    }
    return true;
}

Call like this:

<asp:TextBox ID="foo" runat="server" Rows="3" TextMode="MultiLine" onKeyUp="javascript:Count(this);" onChange="javascript:Count(this);" ></asp:TextBox>

An array in PHP is a map of keys to values:

$array = array();
$array["yellow"] = 3;
$array["green"] = 4;

If you want to do something with each key-value-pair in your array, you can use the foreach control structure:

foreach ($array as $key => $value)

The $array variable is the array you will be using. The $key and $value variables will contain a key-value-pair in every iteration of the foreach loop. In this example, they will first contain "yellow" and 3, then "green" and 4.

You can use an alternative notation if you don't care about the keys:

foreach ($array as $value)

I had the same issue once, the empty POST array is caused due a redirection of the request (on your server side), fix the URL so it doesn't have to be redirected when it hits the server. For Example, if https is forced using the .htaccess file on your server side app, make sure your client request has the "https://" prefix. Usually when a redirect happens the POST array is lost. I Hope this helps!

If you want to know if a string is a number, you could always try parsing it:

var numberString = "123";
int number;

int.TryParse(numberString , out number);

Note that TryParse returns a bool, which you can use to check if your parsing succeeded.

Make sure that your self-signed certificate matches your site URL. If it does not, you will continue to get a certificate error even after explicitly trusting the certificate in Internet Explorer 8 (I don't have Internet Explorer 7, but Firefox will trust the certificate regardless of a URL mismatch).

If this is the problem, the red "Certificate Error" box in Internet Explorer 8 will show "Mismatched Address" as the error after you add your certificate. Also, "View Certificates" has an Issued to: label which shows what URL the certificate is valid against.

        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

 public class CommandHandler : ICommand

    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler

    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }

    }

    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

A simple example of O(1) might be return 23; -- whatever the input, this will return in a fixed, finite time.

A typical example of O(N log N) would be sorting an input array with a good algorithm (e.g. mergesort).

A typical example if O(log N) would be looking up a value in a sorted input array by bisection.

I faced a similar situation. This is probably because the script is executed before the page loads. By placing the script at the bottom of the page, I circumvented the problem.

Use IsNull

SELECT recordid, MIN(startdate), MAX(IsNull(enddate, Getdate()))
FROM tmp 
GROUP BY recordid

I've modified MIN in the second instruction to MAX

Do not access the composer by composer composer.pher install

Personally I prefer static functions over nameless namespaces for the following reasons:

• It's obvious and clear from function definition alone that it's private to the translation unit where it's compiled. With nameless namespace you might need to scroll and search to see if a function is in a namespace.

• Functions in namespaces might be treated as extern by some (older) compilers. In VS2017 they are still extern. For this reason even if a function is in nameless namespace you might still want to mark them static.

• Static functions behave very similar in C or C++, while nameless namespaces are obviously C++ only. nameless namespaces also add extra level in indentation and I don't like that :)

So, I'm happy to see that use of static for functions isn't deprecated anymore.

console.log is what I most often use when debugging.

I was able to find this jQuery extension though.

Well , quite a late answer but it is possible using the curiously recurring template pattern. This wikipedia article has the info you need and also the example under static polymorphism is what you are asked for.

You can add a hidden input with whatever value you need to send:

$('#form').submit(function(eventObj) {
    $(this).append('<input type="hidden" name="someName" value="someValue">');
    return true;
});

You need to use parentheses: myList.insert([1, 2, 3]). When you leave out the parentheses, python thinks you are trying to access myList.insert at position 1, 2, 3, because that's what brackets are used for when they are right next to a variable.

I am using Android Studio 2.1.2. I had same requirement as OP. Though above two answer seemed to help everyone, it did not work for me . I am sharing what worked for me.

Go to main menu/Run/Edit Configuration . Select app under Android Application on the left.This should open multi-tabbed pane . Select General tab ( would be default), click green + sing at the bottom ( below text Before launch: Gradle -awake ...).

A drop down will appear, select Gradle-aware-make option. Another text box will pop up. enter :app:uninstallAll in this text box . (You can use ctrl + space to use autocomplete todetermine right target without typing everything . And also helps you choose the right app name that is avaiable for you). and set apply/ok. Relaunch your app.

Note : Every time you launch your app now , this new target will try to uninstall your app from your emulator or device. So if your testing device is not available, your launc will probably fail while uninstalling but will continue to start your emulator. So Either start your emulator first, or re-lauch after first fail again ( as first launch will start emulator though uninstall fails).

Firstly you should test your python idle to see if you have tkinter:

import tkinter

tkinter._test()

Trying typing it, copy paste doesn't work.

So after 20 hours of trying every way that recommended on those websites figured out that you can't use "tkinter.py" or any other file name that contains "tkinter..etc.py". If you have the same problem, just change the file name.

Flex layout modes are not (fully) natively supported in IE yet. IE10 implements the "tween" version of the spec which is not fully recent, but still works.

This CSS-Tricks article has some advice on cross-browser use of flexbox (including IE): http://css-tricks.com/using-flexbox/

edit: after a bit more research, IE10 flexbox layout mode implemented current to the March 2012 W3C draft spec: http://www.w3.org/TR/2012/WD-css3-flexbox-20120322/

See Stack Overflow question How to make Notepad to save text in UTF-8 without BOM?.

I think that most important information is: Elements in xib are automatically in subviews of view. Subviews is NSArray. NSArray owns it's elements. etc have strong pointers on them. So in most cases you don't want to create another strong pointer (IBOutlet)

And with ARC you don't need to do anything in viewDidUnload

Try like this:

I think you need to use the full path at the command line, something like this, perhaps:

You need to add a dataType - http://api.jquery.com/jQuery.ajax/

$(document).ready(function() {
    $("#lesen").click(function() {
        $.ajax({
            url : "helloworld.txt",
            dataType: "text",
            success : function (data) {
                $(".text").html(data);
            }
        });
    });
}); 

If you're looking to paginate results, use the integrated paginator, it works great!

$games = Game::paginate(30);
// $games->results = the 30 you asked for
// $games->links() = the links to next, previous, etc pages

I had a similar error but with different context when I uploaded a *.p file to Google Drive. I tried to use it later in a Google Colab session, and got this error:

    1 with open("/tmp/train.p", mode='rb') as training_data:
----> 2     train = pickle.load(training_data)
UnpicklingError: invalid load key, '<'.

I solved it by compressing the file, upload it and then unzip on the session. It looks like the pickle file is not saved correctly when you upload/download it so it gets corrupted.

check boxlist selected values with seperator

 string items = string.Empty;
        foreach (ListItem i in CheckBoxList1.Items)
        {
            if (i.Selected == true)
            {
                items += i.Text + ",";
            }
        }
        Response.Write("selected items"+ items);

This Bootply example seems like a much better option. Only thing is that the labels are a little too high so I added padding-top:5px to center them with my inputs.

I am assuming: If you sent the JSON value through browser then any number you sent that will be the type float64 so you cant get the value directly int in golang.

So do the conversion like:

//As that says: 
fmt.Fprintf(w, "Type = %v", val) // <--- Type = float64

var iAreaId int = int(val.(float64))

This way you can get exact value what you wanted.

1. Right click the folder, click on Properties.
2. Click on the Security tab
3. Add the name Everyone to the user list.

Ascii string to integer conversion is done by the atoi() function.

Maybe try the Intl polyfill for IE8 or the olyfill service ?

or

You were almost there:

You just need to append the li to ul and voila!

So just add

ul.appendChild(li);

to the end of your function so the end function will be like this:

function function1() {
  var ul = document.getElementById("list");
  var li = document.createElement("li");
  li.appendChild(document.createTextNode("Element 4"));
  ul.appendChild(li);
}

To run an executable in mac

1). Move to the path of the file:

cd/PATH_OF_THE_FILE

2). Run the following command to set the file's executable bit using the chmod command:

chmod +x ./NAME_OF_THE_FILE

3). Run the following command to execute the file:

./NAME_OF_THE_FILE

Once you have run these commands, going ahead you just have to run command 3, while in the files path.

I wanted to edit several events in descendant chonologic order, and I just made a :

select 
TO_CHAR(startdate,'YYYYMMDD') dateorder,
TO_CHAR(startdate,'DD/MM/YYYY') startdate,
...
from ...
...
order by dateorder desc

and it works for me. But surely not adapted for every case... Just hope it'll help someone !

You'll want to listen for escape's keyCode (27) from the React SyntheticKeyBoardEvent onKeyDown:

const EscapeListen = React.createClass({
  handleKeyDown: function(e) {
    if (e.keyCode === 27) {
      console.log('You pressed the escape key!')
    }
  },

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

Brad Colthurst's CodePen posted in the question's comments is helpful for finding key codes for other keys.

Safely returned default value via generics and LINQ.

public T ReadAppSetting<T>(string searchKey, T defaultValue, StringComparison compare = StringComparison.Ordinal)
{
    if (ConfigurationManager.AppSettings.AllKeys.Any(key => string.Compare(key, searchKey, compare) == 0)) {
        try
        { // see if it can be converted.
            var converter = TypeDescriptor.GetConverter(typeof(T));
            if (converter != null) defaultValue = (T)converter.ConvertFromString(ConfigurationManager.AppSettings.GetValues(searchKey).First());
        }
        catch { } // nothing to do just return the defaultValue
    }
    return defaultValue;
}

Used as follows:

string LogFileName = ReadAppSetting("LogFile","LogFile");
double DefaultWidth = ReadAppSetting("Width",1280.0);
double DefaultHeight = ReadAppSetting("Height",1024.0);
Color DefaultColor = ReadAppSetting("Color",Colors.Black);

I believe that Python 3.1 will print them nicer by default, without any code changing. But that is useless if you use any extensions that haven't been updated to work with Python 3.1

You should either get a window with a list of repositories or a text menu with some options. But if that is not appearing, you can always specify the mirror from where to download the packages yourself by using repos parameter. By doing that, R will not ask you anymore about the repository. Example:

install.packages('RMySQL', repos='http://cran.us.r-project.org')

Here you have a list of mirrors for R.

Try doing it the other way around.

$('<link rel="stylesheet" href="css/style2.css" type="text/css" />').appendTo('head');

Actually, it is less complicated than it seems.

Check out Refit for making calls to REST services from .NET. I've found it very easy to use:

Refit: The automatic type-safe REST library for .NET Core, Xamarin and .NET

Refit is a library heavily inspired by Square's Retrofit library, and it turns your REST API into a live interface:

public interface IGitHubApi {
        [Get("/users/{user}")]
        Task<User> GetUser(string user);
}

// The RestService class generates an implementation of IGitHubApi
// that uses HttpClient to make its calls:

var gitHubApi = RestService.For<IGitHubApi>("https://api.github.com");

var octocat = await gitHubApi.GetUser("octocat");

And don't forget to create a __init__.py with each folder/subfolder (even if they are empty)

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

Apart from a database, you can also have following options to save user related settings

1. registry under HKEY_CURRENT_USER

2. in a file in AppData folder

3. using Settings file in WPF and by setting its scope as User

A better way to solve this problem is to use a function like this:

function scrollToTop(callback, q) {

    if ($('html').scrollTop()) {
        $('html').animate({ scrollTop: 0 }, function() {
            console.log('html scroll');
            callback(q)
        });
        return;
    }

    if ($('body').scrollTop()) {
        $('body').animate({ scrollTop: 0 }, function() {
            console.log('body scroll');
            callback(q)
        });
        return;
    }

    callback(q);
}

This will work across all browsers and prevents FireFox from scrolling up twice (which is what happens if you use the accepted answer - $("html,body").animate({ scrollTop: 0 }, "slow");).

I've tried these solutions and many others, but none of them quite worked out. Since this is the first answer on google, I'll add my solution here.

The method that worked well for me was to take relationships out of the picture during commits, so there was nothing for EF to screw up. I did this by re-finding the parent object in the DBContext, and deleting that. Since the re-found object's navigation properties are all null, the childrens' relationships are ignored during the commit.

var toDelete = db.Parents.Find(parentObject.ID);
db.Parents.Remove(toDelete);
db.SaveChanges();

Note that this assumes the foreign keys are setup with ON DELETE CASCADE, so when the parent row is removed, the children will be cleaned up by the database.

Check if the file path is correct and the file exists - in my case that was the issue - as I fixed it, the error disappeared

Code example:

HashMap<Integer,String> h = new HashMap<Integer,String> ();

h.put(null,null);
h.put(null, "a");

System.out.println(h);

Output:

{null=a}

It overrides the value at key null.

NEVER EVER use a selector like DATE(datecolumns) = '2012-12-24' - it is a performance killer:

• it will calculate DATE() for all rows, including those, that don't match
• it will make it impossible to use an index for the query

It is much faster to use

SELECT * FROM tablename 
WHERE columname BETWEEN '2012-12-25 00:00:00' AND '2012-12-25 23:59:59'

as this will allow index use without calculation.

EDIT

As pointed out by Used_By_Already, in the time since the inital answer in 2012, there have emerged versions of MySQL, where using '23:59:59' as a day end is no longer safe. An updated version should read

SELECT * FROM tablename 
WHERE columname >='2012-12-25 00:00:00'
AND columname <'2012-12-26 00:00:00'

The gist of the answer, i.e. the avoidance of a selector on a calculated expression, of course still stands.

In this context & is causing the function to take stringname by reference. The difference between references and pointers is:

• When you take a reference to a variable, that reference is the variable you referenced. You don't need to dereference it or anything, working with the reference is sematically equal to working with the referenced variable itself.
• NULL is not a valid value to a reference and will result in a compiler error. So generally, if you want to use an output parameter (or a pointer/reference in general) in a C++ function, and passing a null value to that parameter should be allowed, then use a pointer (or smart pointer, preferably). If passing a null value makes no sense for that function, use a reference.
• You cannot 're-seat' a reference. While the value of a pointer can be changed to point at something else, a reference has no similar functionality. Once you take a variable by reference, you are effectively dealing with that variable directly. Just like you can't change the value of a by writing b = 4;. A reference's value is the value of whatever it referenced.

I was trying to @Autowire a Spring-managed service into my Deserializer. Somebody tipped me off to Jackson using the new operator when invoking the serializers/deserializers. This meant no auto-wiring of Jackson's instance of my Deserializer. Here's how I was able to @Autowire my service class into my Deserializer:

context.xml

<mvc:annotation-driven>
  <mvc:message-converters>
    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
      <property name="objectMapper" ref="objectMapper" />
    </bean>
  </mvc:message-converters>
</mvc>
<bean id="objectMapper" class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
    <!-- Add deserializers that require autowiring -->
    <property name="deserializersByType">
        <map key-type="java.lang.Class">
            <entry key="com.acme.Anchor">
                <bean class="com.acme.AnchorDeserializer" />
            </entry>
        </map>
    </property>
</bean>

Now that my Deserializer is a Spring-managed bean, auto-wiring works!

AnchorDeserializer.java

public class AnchorDeserializer extends JsonDeserializer<Anchor> {
    @Autowired
    private AnchorService anchorService;
    public Anchor deserialize(JsonParser parser, DeserializationContext context)
             throws IOException, JsonProcessingException {
        // Do stuff
    }
}

AnchorService.java

@Service
public class AnchorService {}

Update: While my original answer worked for me back when I wrote this, @xi.lin's response is exactly what is needed. Nice find!

There wasn't much hint on performance for the different ways so I performed a test on removing 5000 items from 50000 in all 3 generally different approaches, and for me numpy was the winner (if you have elements that fit in numpy):

• 7.5 sec for the enumerated list comprehension [4.5 sec on another PC]
• 0.08 sec for deleting items in reverse order [0.017 (!) sec]
• 0.009 sec for numpy.delete [0.006 sec]

Here's the code I timed (in the third function conversion from/to list may be removed if working directly on numpy arrays is ok):

import time
import numpy as np
import random

def del_list_indexes(l, id_to_del):
    somelist = [i for j, i in enumerate(l) if j not in id_to_del]
    return somelist

def del_list_inplace(l, id_to_del):
    for i in sorted(id_to_del, reverse=True):
        del(l[i])

def del_list_numpy(l, id_to_del):
    arr = np.array(l, dtype='int32')
    return list(np.delete(arr, id_to_del))

l = range(50000)
random.shuffle(l)
remove_id = random.sample(range(len(l)), 5000) # 10% ==> 5000

# ...

It is all explained by the javadoc for the constructor. It is a convenience constructor that populates the model with one attribute / value pair.

So ...

   new ModelAndView(view, name, value);

is equivalent to:

   Map model = ...
   model.put(name, value);
   new ModelAndView(view, model);

This macro adds a hyperlink to the worksheet with the same name, I also modify the range to be more flexible, just change the first cell in the code. Works like a charm

Sub hyper()
 Dim cl As Range
 Dim nS As String

 Set MyRange = Sheets("Sheet1").Range("B16")
 Set MyRange = Range(MyRange, MyRange.End(xlDown))

 For Each cl In MyRange
  nS = cl.Value
  cl.Hyperlinks.Add Anchor:=cl, Address:="", SubAddress:="'" & nS & "'" & "!B16", TextToDisplay:=nS
 Next
End Sub

I did the following to add a role 'eSumit' on PostgreSQL 9.4.15 database and provide all permission to this role :

CREATE ROLE eSumit;

GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO eSumit;

GRANT ALL PRIVILEGES ON DATABASE "postgres" to eSumit;

ALTER USER eSumit WITH SUPERUSER;

Also checked the pg_table enteries via :

select * from pg_roles;

Database queries snapshot :

change

select op) 

to

select new { op, pg })

You can do this a couple of ways.

Via the "Solution Explorer"

1. Simply right-click the "References" folder and select "Manage NuGet Packages..."
2. Once that window comes up click on the option labeled "Online" in the left most part of the dialog.
3. Then in the search bar in the upper right type "json.net"
4. Click "Install" and you're done.

Via the "Package Manager Console"

1. Open the console. "View" > "Other Windows" > "Package Manager Console"
2. Then type the following:

   Install-Package Newtonsoft.Json

For more info on how to use the "Package Manager Console" check out the nuget docs.

select 
    max(salary) 
from 
    emp_demo_table 
where 
    salary < (select max(salary) from emp_demo_table)

Hope this solves the query in simplest of terms.

Thanks

I had a similar issue when I tried to get a pull with a single quote ' in it's name.

I had to escape the pull request name:

git pull https://github.com/foo/bar namewithsingle"'"quote

JSONP allows you to specify a callback function that is passed your JSON object. This allows you to bypass the same origin policy and load JSON from an external server into the JavaScript on your webpage.

I was recently dealing with an issue when I was trying to get past authentication while making a REST call from Java, and while the answers in this thread (and other threads) helped, there was still a bit of trial and error involved in getting it working.

What worked for me was encoding credentials in Base64 and adding them as Basic Authorization headers. I then added them as an HttpEntity to restTemplate.postForEntity, which gave me the response I needed.

Here's the class I wrote for this in full (extending RestTemplate):

public class AuthorizedRestTemplate extends RestTemplate{

    private String username;
    private String password;

    public AuthorizedRestTemplate(String username, String password){
        this.username = username;
        this.password = password;
    }

    public String getForObject(String url, Object... urlVariables){
        return authorizedRestCall(this, url, urlVariables);
    }

    private String authorizedRestCall(RestTemplate restTemplate, 
            String url, Object... urlVariables){
        HttpEntity<String> request = getRequest();
        ResponseEntity<String> entity = restTemplate.postForEntity(url, 
                request, String.class, urlVariables);
        return entity.getBody();
    }

    private HttpEntity<String> getRequest(){
        HttpHeaders headers = new HttpHeaders();
        headers.add("Authorization", "Basic " + getBase64Credentials());
        return new HttpEntity<String>(headers);
    }

    private String getBase64Credentials(){
        String plainCreds = username + ":" + password;
        byte[] plainCredsBytes = plainCreds.getBytes();
        byte[] base64CredsBytes = Base64.encodeBase64(plainCredsBytes);
        return new String(base64CredsBytes);
    }
}

While using a std::map is fine or using a 256-sized char table would be fine, you could save yourself an enormous amount of space agony by simply using an enum. If you have C++11 features, you can use enum class for strong-typing:

// First, we define base-pairs. Because regular enums
// Pollute the global namespace, I'm using "enum class". 
enum class BasePair {
    A,
    T,
    C,
    G
};

// Let's cut out the nonsense and make this easy:
// A is 0, T is 1, C is 2, G is 3.
// These are indices into our table
// Now, everything can be so much easier
BasePair Complimentary[4] = {
    T, // Compliment of A
    A, // Compliment of T
    G, // Compliment of C
    C, // Compliment of G
};

Usage becomes simple:

int main (int argc, char* argv[] ) {
    BasePair bp = BasePair::A;
    BasePair complimentbp = Complimentary[(int)bp];
}

If this is too much for you, you can define some helpers to get human-readable ASCII characters and also to get the base pair compliment so you're not doing (int) casts all the time:

BasePair Compliment ( BasePair bp ) {
    return Complimentary[(int)bp]; // Move the pain here
}

// Define a conversion table somewhere in your program
char BasePairToChar[4] = { 'A', 'T', 'C', 'G' };
char ToCharacter ( BasePair bp ) {
    return BasePairToChar[ (int)bp ];
}

It's clean, it's simple, and its efficient.

Now, suddenly, you don't have a 256 byte table. You're also not storing characters (1 byte each), and thus if you're writing this to a file, you can write 2 bits per Base pair instead of 1 byte (8 bits) per base pair. I had to work with Bioinformatics Files that stored data as 1 character each. The benefit is it was human-readable. The con is that what should have been a 250 MB file ended up taking 1 GB of space. Movement and storage and usage was a nightmare. Of coursse, 250 MB is being generous when accounting for even Worm DNA. No human is going to read through 1 GB worth of base pairs anyhow.

document.getElementById('loginSubmit').submit();

or, use the same code as the onclick handler:

changeAction('submitInput','loginForm');
document.forms['loginForm'].submit();

(Though that onclick handler is kind of stupidly-written: document.forms['loginForm'] could be replaced with this.)

String fname = "Sam\u0025";

PreparedStatement ps= conn.prepareStatement("SELECT * FROM Users WHERE User_FirstName LIKE ? ");

ps.setString(1, fname);

Just adding onto what has already been said but the setTimeout version of the code will also reach the Maximum call stack size which will stop it from functioning. Since there is no base case for the recursive function to stop at so you can't have it run forever.

Typescript version of @justin answer, ES6 compatible, using Symbols to prevent any key collision and added into the global Object.id for convenience. Just copy paste the code below, or put it into an ObjecId.ts file you will import.

(enableObjectID)();

declare global {
    interface ObjectConstructor {
        id: (object: any) => number;
    }
}

const uniqueId: symbol = Symbol('The unique id of an object');

export function enableObjectID(): void {
    if (typeof Object['id'] !== 'undefined') {
        return;
    }

    let id: number = 0;

    Object['id'] = (object: any) => {
        const hasUniqueId: boolean = !!object[uniqueId];
        if (!hasUniqueId) {
            object[uniqueId] = ++id;
        }

        return object[uniqueId];
    };
}

Example of usage:

console.log(Object.id(myObject));

This is still a matplotlib object. Try this:

# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)

vi your_filename

hit esc

Type :%!xxd to view the hex strings, the n :%!xxd -r to return to normal editing.

As a general rule of thumb, I use 1 cm margins when producing pdfs. I work in the geospatial industry and produce pdf maps that reference a specific geographic scale. Therefore, I do not have the option to 'fit document to printable area,' because this would make the reference scale inaccurate. You must also realize that when you fit to printable area, you are fitting your already existing margins inside the printer margins, so you end up with double margins. Make your margins the right size and your documents will print perfectly. Many modern printers can print with margins less than 3 mm, so 1 cm as a general rule should be sufficient. However, if it is a high profile job, get the specs of the printer you will be printing with and ensure that your margins are adequate. All you need is the brand and model number and you can find spec sheets through a google search.

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

I always use the DisplayName, Description and DefaultValue attributes over public properties of my user controls, custom controls or any class I'll edit through a property grid. These tags are used by the .NET PropertyGrid to format the name, the description panel, and bolds values that are not set to the default values.

[DisplayName("Error color")]
[Description("The color used on nodes containing errors.")]
[DefaultValue(Color.Red)]
public Color ErrorColor
{
    ...
} 

I just wish Visual Studio's IntelliSense would take the Description attribute into account if no XML comment are found. It would avoid having to repeat the same sentence twice.

This is possible due to type erasure. You will find that

List<TestA> x = new ArrayList<TestA>();
List<TestB> y = new ArrayList<TestB>();
x.getClass().equals(y.getClass()); // true

Internally both lists are of type List<Object>. For that reason you can't cast one to the other - there is nothing to cast.

You don't need to find the file.

Only write this instruction on terminal:

git config --global --edit

Try this to read a file:

BufferedReader reader = null;

try {
    File file = new File("sample-file.dat");
    reader = new BufferedReader(new FileReader(file));

    String line;
    while ((line = reader.readLine()) != null) {
        System.out.println(line);
    }

} catch (IOException e) {
    e.printStackTrace();
} finally {
    try {
        reader.close();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

You can pass multiple arguments like this.

List<object> arguments = new List<object>();
arguments.Add("first");      //argument 1
arguments.Add(new Object()); //argument 2
// ...
arguments.Add(10);           //argument n

backgroundWorker.RunWorkerAsync(arguments);

private void worker_DoWork(object sender, DoWorkEventArgs e) 
{
  List<object> genericlist = e.Argument as List<object>;
  //extract your multiple arguments from 
  //this list and cast them and use them. 
}

C++11

Problem

While the rules in C++03 about when you need typename and template are largely reasonable, there is one annoying disadvantage of its formulation

template<typename T>
struct A {
  typedef int result_type;

  void f() {
    // error, "this" is dependent, "template" keyword needed
    this->g<float>();

    // OK
    g<float>();

    // error, "A<T>" is dependent, "typename" keyword needed
    A<T>::result_type n1;

    // OK
    result_type n2; 
  }

  template<typename U>
  void g();
};

As can be seen, we need the disambiguation keyword even if the compiler could perfectly figure out itself that A::result_type can only be int (and is hence a type), and this->g can only be the member template g declared later (even if A is explicitly specialized somewhere, that would not affect the code within that template, so its meaning cannot be affected by a later specialization of A!).

Current instantiation

To improve the situation, in C++11 the language tracks when a type refers to the enclosing template. To know that, the type must have been formed by using a certain form of name, which is its own name (in the above, A, A<T>, ::A<T>). A type referenced by such a name is known to be the current instantiation. There may be multiple types that are all the current instantiation if the type from which the name is formed is a member/nested class (then, A::NestedClass and A are both current instantiations).

Based on this notion, the language says that CurrentInstantiation::Foo, Foo and CurrentInstantiationTyped->Foo (such as A *a = this; a->Foo) are all member of the current instantiation if they are found to be members of a class that is the current instantiation or one of its non-dependent base classes (by just doing the name lookup immediately).

The keywords typename and template are now not required anymore if the qualifier is a member of the current instantiation. A keypoint here to remember is that A<T> is still a type-dependent name (after all T is also type dependent). But A<T>::result_type is known to be a type - the compiler will "magically" look into this kind of dependent types to figure this out.

struct B {
  typedef int result_type;
};

template<typename T>
struct C { }; // could be specialized!

template<typename T>
struct D : B, C<T> {
  void f() {
    // OK, member of current instantiation!
    // A::result_type is not dependent: int
    D::result_type r1;

    // error, not a member of the current instantiation
    D::questionable_type r2;

    // OK for now - relying on C<T> to provide it
    // But not a member of the current instantiation
    typename D::questionable_type r3;        
  }
};

That's impressive, but can we do better? The language even goes further and requires that an implementation again looks up D::result_type when instantiating D::f (even if it found its meaning already at definition time). When now the lookup result differs or results in ambiguity, the program is ill-formed and a diagnostic must be given. Imagine what happens if we defined C like this

template<>
struct C<int> {
  typedef bool result_type;
  typedef int questionable_type;
};

A compiler is required to catch the error when instantiating D<int>::f. So you get the best of the two worlds: "Delayed" lookup protecting you if you could get in trouble with dependent base classes, and also "Immediate" lookup that frees you from typename and template.

Unknown specializations

In the code of D, the name typename D::questionable_type is not a member of the current instantiation. Instead the language marks it as a member of an unknown specialization. In particular, this is always the case when you are doing DependentTypeName::Foo or DependentTypedName->Foo and either the dependent type is not the current instantiation (in which case the compiler can give up and say "we will look later what Foo is) or it is the current instantiation and the name was not found in it or its non-dependent base classes and there are also dependent base classes.

Imagine what happens if we had a member function h within the above defined A class template

void h() {
  typename A<T>::questionable_type x;
}

In C++03, the language allowed to catch this error because there could never be a valid way to instantiate A<T>::h (whatever argument you give to T). In C++11, the language now has a further check to give more reason for compilers to implement this rule. Since A has no dependent base classes, and A declares no member questionable_type, the name A<T>::questionable_type is neither a member of the current instantiation nor a member of an unknown specialization. In that case, there should be no way that that code could validly compile at instantiation time, so the language forbids a name where the qualifier is the current instantiation to be neither a member of an unknown specialization nor a member of the current instantiation (however, this violation is still not required to be diagnosed).

Examples and trivia

You can try this knowledge on this answer and see whether the above definitions make sense for you on a real-world example (they are repeated slightly less detailed in that answer).

The C++11 rules make the following valid C++03 code ill-formed (which was not intended by the C++ committee, but will probably not be fixed)

struct B { void f(); };
struct A : virtual B { void f(); };

template<typename T>
struct C : virtual B, T {
  void g() { this->f(); }
};

int main() { 
  C<A> c; c.g(); 
}

This valid C++03 code would bind this->f to A::f at instantiation time and everything is fine. C++11 however immediately binds it to B::f and requires a double-check when instantiating, checking whether the lookup still matches. However when instantiating C<A>::g, the Dominance Rule applies and lookup will find A::f instead.

You can have awk do it all without using cut:

awk '{print substr($7,index($7,"=")+1)}' inputfile

You could use split() instead of substr(index()).

$(...)[index]      // gives you the DOM element at index
$(...).get(index)  // gives you the DOM element at index
$(...).eq(index)   // gives you the jQuery object of element at index

DOM objects don't have css function, use the last...

$('ul li').eq(index).css({'background-color':'#343434'});

docs:

.get(index) Returns: Element

• Description: Retrieve the DOM elements matched by the jQuery object.
• See: https://api.jquery.com/get/

.eq(index) Returns: jQuery

• Description: Reduce the set of matched elements to the one at the specified index.
• See: https://api.jquery.com/eq/

Datetime formatting is performed by the org.joda.time.format.DateTimeFormatter class. Three classes provide factory methods to create formatters, and this is one. The others are ISODateTimeFormat and DateTimeFormatterBuilder.

DateTimeFormatter format = DateTimeFormat.forPattern("yyyy-MMM-dd");
LocalDate lDate = new LocalDate().parse("2005-nov-12",format);

final org.joda.time.LocalDate class is an immutable datetime class representing a date without a time zone. LocalDate is thread-safe and immutable, provided that the Chronology is as well. All standard Chronology classes supplied are thread-safe and immutable.

node v6.6.0

If you just use in development. You can do this:

npm i babel-cli babel-plugin-transform-async-to-generator babel-polyfill --save-dev

the package.json would be like this:

"devDependencies": {
   "babel-cli": "^6.18.0",
   "babel-plugin-transform-async-to-generator": "^6.16.0",
   "babel-polyfill": "^6.20.0"
}

create .babelrc file and write this:

{
  "plugins": ["transform-async-to-generator"]
}

and then, run your async/await script like this:

./node_modules/.bin/babel-node script.js

Pro tips: using AVD with dnsmasq on Linux

To understand you to read Set up Android Emulator networking from Android Studio.

The loopback of the emulated device is 127.0.0.1 and the host loopback can be accessed from the emulated device from 10.0.2.2.

At startup, the emulated device set its DNS nameserver by picking those from the host in /etc/resolv.conf.

But the point is, if you are using dnsmasq, you setnameserver 127.0.0.1in/etc/resolv.conf` so the emulated device will hit it's own loopback where nothing is running instead of the host loopback where there is a DNS server running.

To solve that, add -dns-server when running AVD from the CLI.

For example:

• Cloudflare DNS: ~/Android/Sdk/emulator/emulator -avd Nexus_9_API_23 -dns-server 1.1.1.1
• Host's dnsmasq: ~/Android/Sdk/emulator/emulator -avd Nexus_9_API_23 -dns-server 1.0.2.2

Why are these new categories needed? Are the WG21 gods just trying to confuse us mere mortals?

I don't feel that the other answers (good though many of them are) really capture the answer to this particular question. Yes, these categories and such exist to allow move semantics, but the complexity exists for one reason. This is the one inviolate rule of moving stuff in C++11:

Thou shalt move only when it is unquestionably safe to do so.

That is why these categories exist: to be able to talk about values where it is safe to move from them, and to talk about values where it is not.

In the earliest version of r-value references, movement happened easily. Too easily. Easily enough that there was a lot of potential for implicitly moving things when the user didn't really mean to.

Here are the circumstances under which it is safe to move something:

1. When it's a temporary or subobject thereof. (prvalue)
2. When the user has explicitly said to move it.

If you do this:

SomeType &&Func() { ... }

SomeType &&val = Func();
SomeType otherVal{val};

What does this do? In older versions of the spec, before the 5 values came in, this would provoke a move. Of course it does. You passed an rvalue reference to the constructor, and thus it binds to the constructor that takes an rvalue reference. That's obvious.

There's just one problem with this; you didn't ask to move it. Oh, you might say that the && should have been a clue, but that doesn't change the fact that it broke the rule. val isn't a temporary because temporaries don't have names. You may have extended the lifetime of the temporary, but that means it isn't temporary; it's just like any other stack variable.

If it's not a temporary, and you didn't ask to move it, then moving is wrong.

The obvious solution is to make val an lvalue. This means that you can't move from it. OK, fine; it's named, so its an lvalue.

Once you do that, you can no longer say that SomeType&& means the same thing everwhere. You've now made a distinction between named rvalue references and unnamed rvalue references. Well, named rvalue references are lvalues; that was our solution above. So what do we call unnamed rvalue references (the return value from Func above)?

It's not an lvalue, because you can't move from an lvalue. And we need to be able to move by returning a &&; how else could you explicitly say to move something? That is what std::move returns, after all. It's not an rvalue (old-style), because it can be on the left side of an equation (things are actually a bit more complicated, see this question and the comments below). It is neither an lvalue nor an rvalue; it's a new kind of thing.

What we have is a value that you can treat as an lvalue, except that it is implicitly moveable from. We call it an xvalue.

Note that xvalues are what makes us gain the other two categories of values:

• A prvalue is really just the new name for the previous type of rvalue, i.e. they're the rvalues that aren't xvalues.

• Glvalues are the union of xvalues and lvalues in one group, because they do share a lot of properties in common.

So really, it all comes down to xvalues and the need to restrict movement to exactly and only certain places. Those places are defined by the rvalue category; prvalues are the implicit moves, and xvalues are the explicit moves (std::move returns an xvalue).

for link in links:
    url = urllib.parse.unquote(webElement.get_attribute("href")) # decode the url
    url = re.sub("^.*?(?:url\?q=)(.*?)&sa.*", r"\1", url, 0, re.IGNORECASE) # get the clean url

Please note that the element id/name/class (@class='r') ** will change depending on the user agent**.
The above code used PhantomJS default user agent.

Everyone is answering correctly about the transparency but not listening to what the guy needs in regards to the list scrolling behind the footer.

You need to make the footer part of your ListView. At the moment the list won't scroll behind because the layout of the ListView does not go behind the footer view with the transparency. Make a RelativeLayout and position the transparency at the bottom.

This isn't appropriate in all situations but you can conditionally return false inside the component itself if a certain criteria is or isn't met.

It doesn't unmount the component, but it removes all rendered content. This would only be bad, in my mind, if you have event listeners in the component that should be removed when the component is no longer needed.

import React, { Component } from 'react';

export default class MyComponent extends Component {
    constructor(props) {
        super(props);

        this.state = {
            hideComponent: false
        }
    }

    closeThis = () => {
        this.setState(prevState => ({
            hideComponent: !prevState.hideComponent
        })
    });

    render() {
        if (this.state.hideComponent === true) {return false;}

        return (
            <div className={`content`} onClick={() => this.closeThis}>
                YOUR CODE HERE
            </div>
        );
    }
}

After searching the net, it seams the best solution is saving the file as .xlsb (binary) rather than .xlsm

You have to do two steps:

1. Put all your files (css,js,html code, etc.) into the public folder.
2. Use url({{ URL::asset('images/slides/2.jpg') }}) where images/slides/2.jpg is path of your content.

Similarly you can call js, css etc.

The default behavior is:

1. If the parameter is a primitive type (int, bool, double, ...), Web API tries to get the value from the URI of the HTTP request.

2. For complex types (your own object, for example: Person), Web API tries to read the value from the body of the HTTP request.

So, if you have:

• a primitive type in the URI, or
• a complex type in the body

...then you don't have to add any attributes (neither [FromBody] nor [FromUri]).

But, if you have a primitive type in the body, then you have to add [FromBody] in front of your primitive type parameter in your WebAPI controller method. (Because, by default, WebAPI is looking for primitive types in the URI of the HTTP request.)

Or, if you have a complex type in your URI, then you must add [FromUri]. (Because, by default, WebAPI is looking for complex types in the body of the HTTP request by default.)

Primitive types:

public class UsersController : ApiController
{
    // api/users
    public HttpResponseMessage Post([FromBody]int id)
    {

    }
    // api/users/id
    public HttpResponseMessage Post(int id)
    {

    }       
}

Complex types:

public class UsersController : ApiController
{       
    // api/users
    public HttpResponseMessage Post(User user)
    {

    }

    // api/users/user
    public HttpResponseMessage Post([FromUri]User user)
    {

    }       
}

This works as long as you send only one parameter in your HTTP request. When sending multiple, you need to create a custom model which has all your parameters like this:

public class MyModel
{
    public string MyProperty { get; set; }
    public string MyProperty2 { get; set; }
}

[Route("search")]
[HttpPost]
public async Task<dynamic> Search([FromBody] MyModel model)
{
    // model.MyProperty;
    // model.MyProperty2;
}

From Microsoft's documentation for parameter binding in ASP.NET Web API:

When a parameter has [FromBody], Web API uses the Content-Type header to select a formatter. In this example, the content type is "application/json" and the request body is a raw JSON string (not a JSON object). At most one parameter is allowed to read from the message body.

This should work:

public HttpResponseMessage Post([FromBody] string name) { ... }

This will not work:

// Caution: This won't work!    
public HttpResponseMessage Post([FromBody] int id, [FromBody] string name) { ... }

The reason for this rule is that the request body might be stored in a non-buffered stream that can only be read once.

You are trying to use it as a CSS file, probably by using

<link rel=stylesheet href=ABCD.html>

or

<style>
@import url("ABCD.html");
</style>

If you have a view with no background this line will help you

android:outlineProvider="bounds"

By default shadow is determined by view's background, so if there is no background, there will be no shadow also.

I had the same problem however, with a Jenkins installation. The response back from trying to clone was always:

stderr: fatal: unable to access 'https://my.gitlab.server/group/repo.git/': Empty reply from server

Unfortunately switching to http wasn't an option, so I needed the root cause. Turns out there was a http setting in the global config for the Jenkins user (likely added when we were running a self-signed cert on out gitlab instance). Taking look at the global config:

$ git config --global -l
http.sslverify=false

Removing this did the trick

$ git config --global --unset http.sslverify

(It also looks like this is a typo, with the correct key http.sslVerify)

Use the synchronisation context if you want to send a result to the UI thread. I needed to change the thread priority so I changed from using thread pool threads (commented out code) and created a new thread of my own. I was still able to use the synchronisation context to return whether the database cancel succeeded or not.

    #region SyncContextCancel

    private SynchronizationContext _syncContextCancel;

    /// <summary>
    /// Gets the synchronization context used for UI-related operations.
    /// </summary>
    /// <value>The synchronization context.</value>
    protected SynchronizationContext SyncContextCancel
    {
        get { return _syncContextCancel; }
    }

    #endregion //SyncContextCancel

    public void CancelCurrentDbCommand()
    {
        _syncContextCancel = SynchronizationContext.Current;

        //ThreadPool.QueueUserWorkItem(CancelWork, null);

        Thread worker = new Thread(new ThreadStart(CancelWork));
        worker.Priority = ThreadPriority.Highest;
        worker.Start();
    }

    SQLiteConnection _connection;
    private void CancelWork()//object state
    {
        bool success = false;

        try
        {
            if (_connection != null)
            {
                log.Debug("call cancel");
                _connection.Cancel();
                log.Debug("cancel complete");
                _connection.Close();
                log.Debug("close complete");
                success = true;
                log.Debug("long running query cancelled" + DateTime.Now.ToLongTimeString());
            }
        }
        catch (Exception ex)
        {
            log.Error(ex.Message, ex);
        }

        SyncContextCancel.Send(CancelCompleted, new object[] { success });
    }

    public void CancelCompleted(object state)
    {
        object[] args = (object[])state;
        bool success = (bool)args[0];

        if (success)
        {
            log.Debug("long running query cancelled" + DateTime.Now.ToLongTimeString());

        }
    }

You can run nodejs using pm2 if you want to manage each microservice means and run it. Node will be running in a port right just configure that port in nginx(/etc/nginx/sites-enabled/domain.com)

server{
    listen 80;
    server_name domain.com www.domain.com;

  location / {
     return 403;
  }
    location /url {
        proxy_pass http://localhost:51967/info;
    }
}

Check whether localhost is running or not by using ping.

And

Create one single Node.js server which handles all Node.js requests. This reads the requested files and evals their contents. So the files are interpreted on each request, but the server logic is much simpler.

This is best and as you said easier too

How i do it!

boolean run = false;

int ticks = 0;

long tickstart;

int fps;

public void loop()
{
if(this.ticks==0)
{
this.tickstart = System.currentTimeMillis();
}
this.ticks++;
this.fps = (int)this.ticks / (System.currentTimeMillis()-this.tickstart);
}

In words, a tick clock tracks ticks. If it is the first time, it takes the current time and puts it in 'tickstart'. After the first tick, it makes the variable 'fps' equal how many ticks of the tick clock divided by the time minus the time of the first tick.

Fps is an integer, hence "(int)".

For me this error happened because I was trying to call a nested function. Only thing I had to do to have it fixed was to bring the function out to a scope where it was visible.

Editor's note: disabling SSL verification has security implications. Without verification of the authenticity of SSL/HTTPS connections, a malicious attacker can impersonate a trusted endpoint such as Gmail, and you'll be vulnerable to a Man-in-the-Middle Attack.

Be sure you fully understand the security issues before using this as a solution.

I have also this error in laravel 4.2 I solved like this way. Find out StreamBuffer.php. For me I use xampp and my project name is itis_db for this my path is like this. So try to find according to your one

C:\xampp\htdocs\itis_db\vendor\swiftmailer\swiftmailer\lib\classes\Swift\Transport\StreamBuffer.php

and find out this function inside StreamBuffer.php

private function _establishSocketConnection()

and paste this two lines inside of this function

$options['ssl']['verify_peer'] = FALSE;
$options['ssl']['verify_peer_name'] = FALSE;

and reload your browser and try to run your project again. For me I put on like this:

private function _establishSocketConnection()
{
    $host = $this->_params['host'];
    if (!empty($this->_params['protocol'])) {
        $host = $this->_params['protocol'].'://'.$host;
    }
    $timeout = 15;
    if (!empty($this->_params['timeout'])) {
        $timeout = $this->_params['timeout'];
    }
    $options = array();
    if (!empty($this->_params['sourceIp'])) {
        $options['socket']['bindto'] = $this->_params['sourceIp'].':0';
    }
    
   $options['ssl']['verify_peer'] = FALSE;
    $options['ssl']['verify_peer_name'] = FALSE;

    $this->_stream = @stream_socket_client($host.':'.$this->_params['port'], $errno, $errstr, $timeout, STREAM_CLIENT_CONNECT, stream_context_create($options));
    if (false === $this->_stream) {
        throw new Swift_TransportException(
            'Connection could not be established with host '.$this->_params['host'].
            ' ['.$errstr.' #'.$errno.']'
            );
    }
    if (!empty($this->_params['blocking'])) {
        stream_set_blocking($this->_stream, 1);
    } else {
        stream_set_blocking($this->_stream, 0);
    }
    stream_set_timeout($this->_stream, $timeout);
    $this->_in = &$this->_stream;
    $this->_out = &$this->_stream;
}

Hope you will solve this problem.....

You can use an svn changelist to keep track of a set of files that you want to commit together.

The linked page goes into lots of details, but here's an executive summary example:

$ svn changelist my-changelist mydir/dir1/file1.c mydir/dir2/myfile1.h
$ svn changelist my-changelist mydir/dir3/myfile3.c etc.
... (add all the files you want to commit together at your own rate)
$ svn commit -m"log msg" --changelist my-changelist

you can get the nodejs configuration from http://nodejs.org/
The important thing you need to keep in your mind is about its configuration in file app.js which consists of port number host and other settings these are settings working for me

backendSettings = {
"scheme":"https / http ",
"host":"Your website url",
"port":49165, //port number 
'sslKeyPath': 'Path for key',
'sslCertPath': 'path for SSL certificate',
'sslCAPath': '',
"resource":"/socket.io",
"baseAuthPath": '/nodejs/',
"publishUrl":"publish",
"serviceKey":"",
"backend":{
"port":443,
"scheme": 'https / http', //whatever is your website scheme
"host":"host name",
"messagePath":"/nodejs/message/"},
"clientsCanWriteToChannels":false,
"clientsCanWriteToClients":false,
"extensions":"",
"debug":false,
"addUserToChannelUrl": 'user/channel/add/:channel/:uid',
"publishMessageToContentChannelUrl": 'content/token/message',
"transports":["websocket",
"flashsocket",
"htmlfile",
"xhr-polling",
"jsonp-polling"],
"jsMinification":true,
"jsEtag":true,
"logLevel":1};

In this if you are getting "Error: listen EADDRINUSE" then please change the port number i.e, here I am using "49165" so you can use other port such as 49170 or some other port. For this you can refer to the following article
http://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-shared-hosting-accounts

You have to use an image to change the actual size or form of the bullet itself:

You can use a background image with appropriate padding to nudge content so it doesn't overlap:

list-style-image:url(bigger.gif);

or

background-image: url(images/bullet.gif);

If you just want to output the first 5 elements, you should write something like:

<?php

  if (!empty ( $an_array ) ) {

    $min = min ( count ( $an_array ), 5 );

    $i = 0;

    foreach ($value in $an_array) {

      echo $value;
      $i++;
      if ($i == $min) break;

    }

  }

?>

If you want to write a function which returns part of the array, you should use array_slice:

<?php

  function GetElements( $an_array, $elements ) {
    return array_slice( $an_array, 0, $elements );
  }

?>

For better performance use str1.concat(str2) where str1 and str2 are string variables.

Ok, I think I was able to find a proper solution for that.

Now, instead of sending <Link/> as prop to Document, I send <NextLink/> which is a custom wrapper for the react-router Link. By doing that, I'm able to have the right arrow as part of the Link structure while still avoiding to have routing code inside Document object.

The updated code looks like follows:

//in NextLink.js
var React = require('react');
var Right = require('./Right');

var NextLink = React.createClass({
    propTypes: {
        link: React.PropTypes.node.isRequired
    },

    contextTypes: {
        transitionTo: React.PropTypes.func.isRequired
    },

    _onClickRight: function() {
        this.context.transitionTo(this.props.link.props.to);
    },

    render: function() {
        return (
            <div>
                {this.props.link}
                <Right onClick={this._onClickRight} />
            </div>  
        );
    }
});

module.exports = NextLink;

...
//in MasterPage.js
var sampleLink = <Link to="/sample">Go To Sample</Link>
var nextLink = <NextLink link={sampleLink} />
<Document next={nextLink} />

//in Document.js
...
var Document = React.createClass({
   render: function() {
      return (
         ...
         <div>{this.props.next}</div>
         ...
      );
   }
});
...

P.S: If you are using the latest version of react-router you may need to use this.context.router.transitionTo instead of this.context.transitionTo. This code will work fine for react-router version 0.12.X.

Yes to the first question and no to the second question; it's a virtual machine. Your problems are probably related to unspecified changes in library implementation between versions. Although it could be, say, a race condition.

There are some hoops the VM has to go through. Notably references are treated in class files as if they took the same space as ints on the stack. double and long take up two reference slots. For instance fields, there's some rearrangement the VM usually goes through anyway. This is all done (relatively) transparently.

Also some 64-bit JVMs use "compressed oops". Because data is aligned to around every 8 or 16 bytes, three or four bits of the address are useless (although a "mark" bit may be stolen for some algorithms). This allows 32-bit address data (therefore using half as much bandwidth, and therefore faster) to use heap sizes of 35- or 36-bits on a 64-bit platform.

Since rebasing is so fundamental, here's an expansion of Nestor Milyaev's answer. Combining jsz's and Simon South's comments from Adam Dymitruk's answer yields this command which works on the topic branch regardless of whether it branches from the master branch's commit A or C:

git checkout topic
git rebase --onto <commit-B> <pre-rebase-A-or-post-rebase-C-or-base-branch-name>

Note that the last argument is required (otherwise it rewinds your branch to commit B).

Examples:

# if topic branches from master commit A:
git checkout topic
git rebase --onto <commit-B> <commit-A>

# if topic branches from master commit C:
git checkout topic
git rebase --onto <commit-B> <commit-C>

# regardless of whether topic branches from master commit A or C:
git checkout topic
git rebase --onto <commit-B> master

So the last command is the one that I typically use.

Maybe specifying a width would work. When you position:absolute an element, it's width will shrink to the contents I believe.

Guava almost always has what you need.

ThreadFactory namedThreadFactory = 
  new ThreadFactoryBuilder().setNameFormat("my-sad-thread-%d").build()

and pass it off to your ExecutorService.

Another solution:

select * from traintable
where (train, time) in (select train, max(time) from traintable group by train);

PUT and PATCH methods are similar in nature, but there is a key difference.

PUT - in PUT request, the enclosed entity would be considered as the modified version of a resource which residing on server and it would be replaced by this modified entity.

PATCH - in PATCH request, enclosed entity contains the set of instructions that how the entity which residing on server, would be modified to produce a newer version.

The == operator checks to see if two objects are exactly the same object. Two strings may be different objects, but have the same value (have exactly the same characters in them). Use the .equals() method to compare strings for equality.

Yeah it is possible with FileReader, I have already done an example of this, here's the code:

<!DOCTYPE html>
<html>
  <head>
    <title>Read File (via User Input selection)</title>
    <script type="text/javascript">
    var reader; //GLOBAL File Reader object for demo purpose only

    /**
     * Check for the various File API support.
     */
    function checkFileAPI() {
        if (window.File && window.FileReader && window.FileList && window.Blob) {
            reader = new FileReader();
            return true; 
        } else {
            alert('The File APIs are not fully supported by your browser. Fallback required.');
            return false;
        }
    }

    /**
     * read text input
     */
    function readText(filePath) {
        var output = ""; //placeholder for text output
        if(filePath.files && filePath.files[0]) {           
            reader.onload = function (e) {
                output = e.target.result;
                displayContents(output);
            };//end onload()
            reader.readAsText(filePath.files[0]);
        }//end if html5 filelist support
        else if(ActiveXObject && filePath) { //fallback to IE 6-8 support via ActiveX
            try {
                reader = new ActiveXObject("Scripting.FileSystemObject");
                var file = reader.OpenTextFile(filePath, 1); //ActiveX File Object
                output = file.ReadAll(); //text contents of file
                file.Close(); //close file "input stream"
                displayContents(output);
            } catch (e) {
                if (e.number == -2146827859) {
                    alert('Unable to access local files due to browser security settings. ' + 
                     'To overcome this, go to Tools->Internet Options->Security->Custom Level. ' + 
                     'Find the setting for "Initialize and script ActiveX controls not marked as safe" and change it to "Enable" or "Prompt"'); 
                }
            }       
        }
        else { //this is where you could fallback to Java Applet, Flash or similar
            return false;
        }       
        return true;
    }   

    /**
     * display content using a basic HTML replacement
     */
    function displayContents(txt) {
        var el = document.getElementById('main'); 
        el.innerHTML = txt; //display output in DOM
    }   
</script>
</head>
<body onload="checkFileAPI();">
    <div id="container">    
        <input type="file" onchange='readText(this)' />
        <br/>
        <hr/>   
        <h3>Contents of the Text file:</h3>
        <div id="main">
            ...
        </div>
    </div>
</body>
</html>

It's also possible to do the same thing to support some older versions of IE (I think 6-8) using the ActiveX Object, I had some old code which does that too but its been a while so I'll have to dig it up I've found a solution similar to the one I used courtesy of Jacky Cui's blog and edited this answer (also cleaned up code a bit). Hope it helps.

Lastly, I just read some other answers that beat me to the draw, but as they suggest, you might be looking for code that lets you load a text file from the server (or device) where the JavaScript file is sitting. If that's the case then you want AJAX code to load the document dynamically which would be something as follows:

<!DOCTYPE html>
<html>
<head><meta charset="utf-8" />
<title>Read File (via AJAX)</title>
<script type="text/javascript">
var reader = new XMLHttpRequest() || new ActiveXObject('MSXML2.XMLHTTP');

function loadFile() {
    reader.open('get', 'test.txt', true); 
    reader.onreadystatechange = displayContents;
    reader.send(null);
}

function displayContents() {
    if(reader.readyState==4) {
        var el = document.getElementById('main');
        el.innerHTML = reader.responseText;
    }
}

</script>
</head>
<body>
<div id="container">
    <input type="button" value="test.txt"  onclick="loadFile()" />
    <div id="main">
    </div>
</div>
</body>
</html>

If a TestRestTemplate is a valid option in your unit test, this documentation might be relevant

http://docs.spring.io/spring-boot/docs/1.4.1.RELEASE/reference/htmlsingle/#boot-features-rest-templates-test-utility

Short answer: if using

@SpringBootTest(webEnvironment=WebEnvironment.RANDOM_PORT)

then @Autowired will work. If using

@SpringBootTest(webEnvironment=WebEnvironment.MOCK)

then create a TestRestTemplate like this

private TestRestTemplate template = new TestRestTemplate();

In the nav go View => Layout => Columns:2 (alt+shift+2) and open your file again in the other pane (i.e. click the other pane and use ctrl+p filename.py)

It appears you can also reopen the file using the command File -> New View into File which will open the current file in a new tab

Easy install for ubuntu:

Just run:

sudo apt-get install php5-pgsql

then

sudo service apache2 restart //restart apache

or

Uncomment the following in php.ini by removing the ;

;extension=php_pgsql.dll

then restart apache

The best approach to use yum and update your devtoolset is to utilize the CentOS SCLo RH Testing repository.

yum install centos-release-scl-rh
yum --enablerepo=centos-sclo-rh-testing install devtoolset-7-gcc devtoolset-7-gcc-c++

Many additional packages are also available, to see them all

yum --enablerepo=centos-sclo-rh-testing list devtoolset-7*

You can use this method to install any dev tool version, just swap the 7 for your desired version. devtoolset-6-gcc, devtoolset-5-gcc etc.

When I found this solution I was looking for something slightly different as the string I wanted to count was longer than one character, so I came up with this solution:

    Public Shared Function StrCounter(str As String, CountStr As String) As Integer
        Dim Ctr As Integer = 0
        Dim Ptr As Integer = 1
        While InStr(Ptr, str, CountStr) > 0
            Ptr = InStr(Ptr, str, CountStr) + Len(CountStr)
            Ctr += 1
        End While
        Return Ctr
    End Function

$('#' + catId).parent().remove('.subcatBtns');

No, this looks like the recommended way to calculate directory size, the relevent method included below:

public static long DirSize(DirectoryInfo d) 
{    
    long size = 0;    
    // Add file sizes.
    FileInfo[] fis = d.GetFiles();
    foreach (FileInfo fi in fis) 
    {      
        size += fi.Length;    
    }
    // Add subdirectory sizes.
    DirectoryInfo[] dis = d.GetDirectories();
    foreach (DirectoryInfo di in dis) 
    {
        size += DirSize(di);   
    }
    return size;  
}

You would call with the root as:

Console.WriteLine("The size is {0} bytes.", DirSize(new DirectoryInfo(targetFolder));

...where targetFolder is the folder-size to calculate.

You can use the str.split method: string.split('__')

>>> "MATCHES__STRING".split("__")
['MATCHES', 'STRING']

There is one more option that I recently discovered that some people may find useful because it allows you to change a CSS rule within a style element - thus avoiding the need for repeated use of an angular directive such as ng-style, ng-class, ng-show, ng-hide, ng-animate, and others.

This option makes use of a service with service variables which are set by a controller and watched by an attribute-directive I call "custom-style". This strategy could be used in many different ways, and I attempted to provide some general guidance with this fiddle.

var app = angular.module('myApp', ['ui.bootstrap']);
app.service('MainService', function(){
    var vm = this;
});
app.controller('MainCtrl', function(MainService){
    var vm = this;
    vm.ms = MainService;
});
app.directive('customStyle', function(MainService){
    return {
        restrict : 'A',
        link : function(scope, element, attr){
            var style = angular.element('<style></style>');
            element.append(style);
            scope.$watch(function(){ return MainService.theme; },
                function(){
                    var css = '';
                    angular.forEach(MainService.theme, function(selector, key){
                        angular.forEach(MainService.theme[key], function(val, k){
                            css += key + ' { '+k+' : '+val+'} ';
                        });                        
                    });
                    style.html(css);
                }, true);
        }
    };
});

It looks like API level 11 has support for what you need. See WebViewClient.shouldInterceptRequest().

If you have multiple markers you can use this simple solution to close a previously opened marker when clicking a new marker:

var infowindow = new google.maps.InfoWindow({
                maxWidth: (window.innerWidth - 160),
                content: content
            });

            marker.infowindow = infowindow;
            var openInfoWindow = '';

            marker.addListener('click', function (map, marker) {
                if (openInfoWindow) {
                    openInfoWindow.close();
                }
                openInfoWindow = this.infowindow;
                this.infowindow.open(map, this);
            });

You are giving the span a 100% width resulting in it expanding to the size of the parent. This means you can’t center-align it, as there is no room to move it.

You could give the span a set width, then add the margin:0 auto again. This would center-align it.

.left 
{
   background-color: #999999;
   height: 50px;
   width: 24.5%;
}
span.panelTitleTxt 
{
   display:block;
   width:100px;
   height: 100%;
   margin: 0 auto;
}

In Filter the response is of ServletResponse rather than HttpServletResponse. Hence do the cast to HttpServletResponse.

HttpServletResponse httpResponse = (HttpServletResponse) response;
httpResponse.sendRedirect("/login.jsp");

If using a context path:

httpResponse.sendRedirect(req.getContextPath() + "/login.jsp");

Also don't forget to call return; at the end.

This is what worked for me..

.table-no-border>thead>tr>th, 
.table-no-border>tbody>tr>th, 
.table-no-border>tfoot>tr>th, 
.table-no-border>thead>tr>td, 
.table-no-border>tbody>tr>td, 
.table-no-border>tfoot>tr>td,
.table-no-border>tbody,
.table-no-border>thead,
.table-no-border>tfoot{
  border-top: none !important; 
  border-bottom: none !important; 
}

Had to whip out the !important to make it stick.

In python, you can put ‘j’ or ‘J’ after a number to make it imaginary, so you can write complex literals easily:

>>> 1j
1j
>>> 1J
1j
>>> 1j * 1j
(-1+0j)

The ‘j’ suffix comes from electrical engineering, where the variable ‘i’ is usually used for current. (Reasoning found here.)

The type of a complex number is complex, and you can use the type as a constructor if you prefer:

>>> complex(2,3)
(2+3j)

A complex number has some built-in accessors:

>>> z = 2+3j
>>> z.real
2.0
>>> z.imag
3.0
>>> z.conjugate()
(2-3j)

Several built-in functions support complex numbers:

>>> abs(3 + 4j)
5.0
>>> pow(3 + 4j, 2)
(-7+24j)

The standard module cmath has more functions that handle complex numbers:

>>> import cmath
>>> cmath.sin(2 + 3j)
(9.15449914691143-4.168906959966565j)

As much as I love XAML, for this kinds of tasks I switch to code behind. Attached behaviors are a good pattern for this. Keep in mind, Expression Blend 3 provides a standard way to program and use behaviors. There are a few existing ones on the Expression Community Site.

setCustomValidity's purpose is not just to set the validation message, it itself marks the field as invalid. It allows you to write custom validation checks which aren't natively supported.

You have two possible ways to set a custom message, an easy one that does not involve Javascript and one that does.

The easiest way is to simply use the title attribute on the input element - its content is displayed together with the standard browser message.

<input type="text" required title="Lütfen isaretli yerleri doldurunuz" />

If you want only your custom message to be displayed, a bit of Javascript is required. I have provided both examples for you in this fiddle.

I believe you must add the namespace to your xml document, with, for example, the use of a SAX filter.

That means:

• Define a ContentHandler interface with a new class which will intercept SAX events before JAXB can get them.
• Define a XMLReader which will set the content handler

then link the two together:

public static Object unmarshallWithFilter(Unmarshaller unmarshaller,
java.io.File source) throws FileNotFoundException, JAXBException 
{
    FileReader fr = null;
    try {
        fr = new FileReader(source);
        XMLReader reader = new NamespaceFilterXMLReader();
        InputSource is = new InputSource(fr);
        SAXSource ss = new SAXSource(reader, is);
        return unmarshaller.unmarshal(ss);
    } catch (SAXException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } catch (ParserConfigurationException e) {
        //not technically a jaxb exception, but close enough
        throw new JAXBException(e);
    } finally {
        FileUtil.close(fr); //replace with this some safe close method you have
    }
}

public <T> List<T> getIntersectOfCollections(Collection<T> first, Collection<T> second) {
        return first.stream()
                .filter(second::contains)
                .collect(Collectors.toList());
    }

There are four options here:

1. Get virtualenv set up. Each virtual environment you create will automatically have pip.

2. Get pip set up globally.

3. Learn how to install Python packages manually—in most cases it's as simple as download, unzip, python setup.py install, but not always.

4. Use Christoph Gohlke's binary installers.

There can be many things:
First attempt, make a select of this field in its source table;
Check the instance of the sql script window, you may be in a different instance;
Check if your join is correct;
Verify query ambiguity, maybe you are making a wrong table reference
Of these checks, run the T-sql script again

worked just fine for me ... Or am I missing something?

Edit: But see Shawn's caveat about accidentally upsizing.

I couldn't get the first method to work, and I know this is an old topic, but this is what I ended up doing for a solution:

=IF(ISNA(MATCH(A1,B:B,0)),"Not Matched", A1)

Basically, MATCH A1 to Column B exactly (the 0 stands for match exactly to a value in Column B). ISNA tests for #N/A response which match will return if the no match is found. Finally, if ISNA is true, write "Not Matched" to the selected cell, otherwise write the contents of the matched cell.

The range of char is 127 to -128. If you assign 212, ch stores -44 (212-128-128) not 212.So if you try to print a negative number as unsigned you get (MAX value of unsigned int)-abs(number) which in this case is 4294967252

So if you want to store 212 as it is in ch the only thing you can do is declare ch as

unsigned char ch;

now the range of ch is 0 to 255.

If you use Java 1.5 or beyond you could use:

List<String> S = new ArrayList<String>();
s.add("My text");

for (String item : S) {
  System.out.println(item);
}

I have used Meld once, which seemed very nice, and I may try more often. vimdiff works well, if you know vim well. Lastly I would mention I've found xxdiff does a reasonable job for a quick comparison. There are many diff programs out there which do a good job.

This was a developer mistake - a misplaced ending brace, which made the above function a nested function.

I see a lot of questions related to the undefined function error in SO. Let me note down this as an answer, in case someone else have the same issue with function scope.

Things I tried to troubleshoot first:

1. Searched for the php file with the function definition in it. Verified that the file exists.
2. Verified that the require (or include) statement for the above file exists in the page. Also, verified the absolute path in the require/include is correct.
3. Verified that the filename is spelled correctly in the require statement.
4. Echoed a word in the included file, to see if it has been properly included.
5. Defined a separate function at the end of file, and called it. It worked too.

It was difficult to trace the braces, since the functions were very long - problem with legacy systems. Further steps to troubleshoot were this:

1. I already defined a simple print function at the end of included file. I moved it to just above the "undefined function". That made it undefined too.

2. Identified this as some scope issue.

3. Used the Netbeans collapse (code fold) feature to check the function just above this one. So, the 1000 lines function above just collapsed along with this one, making this a nested function.

4. Once the problem identified, cut-pasted the function to the end of file, which solved the issue.

The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.

What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!

I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.

So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:

import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;

//  create and initialize an object 
public static JSONObject buildObject( final SimpleEntry... entries ) { 
    JSONObject object = new JSONObject();
    for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
    return object;
}

//  nest a list of objects inside another                          
public static void putObjects( final JSONObject parentObject, final String key,
                               final JSONObject... objects ) { 
    List objectList = new ArrayList<JSONObject>();
    for( JSONObject o : objects ) objectList.add( o );
    parentObject.put( key, objectList );
}   

Implementation example:

JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
    buildObject( 
        new SimpleEntry( "child1Key1", "someValue" )
      , new SimpleEntry( "child1Key2", "someValue" ) 
    )
  , buildObject( 
        new SimpleEntry( "child2Key1", "someValue" )
      , new SimpleEntry( "child2Key2", "someValue" ) 
    )
);      

Check google-services.json file in app folder of your Android project. Generate a new one from Firebase console if you are unsure. I got this error in two cases.

1. I used a test Firebase project with test application (that contained right google-services.json file). Then I tried to send push notification to another application and got this error ('"error": "MismatchSenderId"'). I understood that the second application was bound to another Firebase project with different google-services.json. Because server keys are different, the request should be rewritten.

2. I changed google-services.json in the application, because I wanted to replace test Firebase project with an actual. I generated right google-services.json file, changed request, but kept receiving this error. On the next day it fixed itself. I suspect Firebase doesn't update synchronously.

To get a server key for the request, open https://console.firebase.google.com and select an appropriate project.

Then paste it in the request.

This can be caused by the two sides of the connection disagreeing over whether the connection timed out or not during a keepalive. (Your code tries to reused the connection just as the server is closing it because it has been idle for too long.) You should basically just retry the operation over a new connection. (I'm surprised your library doesn't do this automatically.)

I made a script called realpath personally which looks a little something like:

#!/usr/bin/env python
import os.sys
print os.path.realpath(sys.argv[1])

Adding LoggingPreferences to "goog:loggingPrefs" properties with the Chrome Driver options can help to fetch the Browser console logs for all Log levels.

ChromeOptions options = new ChromeOptions();    
LoggingPreferences logPrefs = new LoggingPreferences();
logPrefs.enable(LogType.BROWSER, Level.ALL);
options.setCapability("goog:loggingPrefs", logPrefs);
WebDriver driver = new ChromeDriver(options);

I found a fix that while it's not actually using ajax it does allow you to use a javascript call to request the download and then get a callback when the download actually starts. I found this helpful if the link runs a server side script that takes a little bit to compose the file before sending it. so you can alert them that it's processing, and then when it does finally send the file remove that processing notification. which is why I wanted to try to load the file via ajax to begin with so that I could have an event happen when the file is requested and another when it actually starts downloading.

the js on the front page

function expdone()
{
    document.getElementById('exportdiv').style.display='none';
}
function expgo()
{
   document.getElementById('exportdiv').style.display='block';
   document.getElementById('exportif').src='test2.php?arguments=data';
}

the iframe

<div id="exportdiv" style="display:none;">
<img src="loader.gif"><br><h1>Generating Report</h1>
<iframe id="exportif" src="" style="width: 1px;height: 1px; border:0px;"></iframe>
</div>

then the other file:

<!DOCTYPE html>
<html>
<head>
<script>
function expdone()
{
    window.parent.expdone();
}
</script>
</head>
<body>
<iframe id="exportif" src="<?php echo "http://10.192.37.211/npdtracker/exportthismonth.php?arguments=".$_GET["arguments"]; ?>"></iframe>
<script>document.getElementById('exportif').onload= expdone;</script>
</body></html>

I think there's a way to read get data using js so then no php would be needed. but I don't know it off hand and the server I'm using supports php so this works for me. thought I'd share it in case it helps anyone.

It's called the carriage return, or \r

Use

print i/len(some_list)*100," percent complete         \r",

The comma prevents print from adding a newline. (and the spaces will keep the line clear from prior output)

Also, don't forget to terminate with a print "" to get at least a finalizing newline!

Describe Formatted/Extended will show the data definition of the table in hive

hive> describe Formatted dbname.tablename;

If you just want to see the values of an array without brackets, you can use a combination of fmt.Sprint() and strings.Trim()

a := []string{"a", "b"}
fmt.Print(strings.Trim(fmt.Sprint(a), "[]"))
fmt.Print(a)

Returns:

a b
[a b]

Be aware though that with this solution any leading brackets will be lost from the first value and any trailing brackets will be lost from the last value

a := []string{"[a]", "[b]"}
fmt.Print(strings.Trim(fmt.Sprint(a), "[]")
fmt.Print(a)

Returns:

a] [b
[[a] [b]]

For more info see the documentation for strings.Trim()

You can use this code SELECT article FROM table1 ORDER BY publish_date LIMIT 0,10 where 0 is a start limit of record & 10 number of record

I have something that seems to me has a bit more order:

import boto3
from pprint import pprint
from botocore.exceptions import NoCredentialsError


class S3(object):
    BUCKET = "test"
    connection = None

    def __init__(self):
        try:
            vars = get_s3_credentials("aws")
            self.connection = boto3.resource('s3', 'aws_access_key_id',
                                             'aws_secret_access_key')
        except(Exception) as error:
            print(error)
            self.connection = None


    def upload_file(self, file_to_upload_path, file_name):
        if file_to_upload is None or file_name is None: return False
        try:
            pprint(file_to_upload)
            file_name = "your-folder-inside-s3/{0}".format(file_name)
            self.connection.Bucket(self.BUCKET).upload_file(file_to_upload_path, 
                                                                      file_name)
            print("Upload Successful")
            return True

        except FileNotFoundError:
            print("The file was not found")
            return False

        except NoCredentialsError:
            print("Credentials not available")
            return False

There're three important variables here, the BUCKET const, the file_to_upload and the file_name

BUCKET: is the name of your S3 bucket

file_to_upload_path: must be the path from file you want to upload

file_name: is the resulting file and path in your bucket (this is where you add folders or what ever)

There's many ways but you can reuse this code in another script like this

import S3

def some_function():
    S3.S3().upload_file(path_to_file, final_file_name)

find in npm module mongodb ..node_modules\mongodb\node_modules\bson\ext\index.js

and change path to js version in catch block

bson = require('../build/Release/bson');

to bson = require('../browser_build/bson');

try {
        // Load the precompiled win32 binary
        if(process.platform == "win32" && process.arch == "x64") {
          bson = require('./win32/x64/bson');  
        } else if(process.platform == "win32" && process.arch == "ia32") {
          bson = require('./win32/ia32/bson');  
        } else {
         bson = require('../browser_build/bson');  
        }   
    } catch(err) {
        // Attempt to load the release bson version
        try {
            bson = require('../browser_build/bson');
        } catch (err) {
            console.dir(err)
            console.error("js-bson: Failed to load c++ bson extension, using pure JS version");
            bson = require('../lib/bson/bson');
        }
    }

A way to use this in react:

class Timeout extends Component {
  constructor(props){
    super(props)

    this.state = {
      timeout: null
    }

  }

  userTimeout(){
    const { timeout } = this.state;
    clearTimeout(timeout);
    this.setState({
      timeout: setTimeout(() => {this.callAPI()}, 250)
    })

  }
}

Helpful if you'd like to only call an API after the user has stopped typing for instance. The userTimeout function could be bound via onKeyUp to an input.

Check, if you are not accidentally requesting HTTPS protocol instead of HTTP.

I have overlooked that I was requesting https://localhost:... instead of http://localhost:... and it resulted to this weird message..
