EDIT: See the latest Fiddle with "fixed header":

The Fiddle.

One of the solutions is to implement scrolling yourself instead of letting DataTables plugin do it for you.

I've taken your example and commented out sScrollX option. When this option is not present DataTables plugin will simply put your table as is into a container div. This table will stretch out of the screen, therefore, to fix that we can put it into a div with required width and an overflow property set - this is exactly what the last jQuery statement does - it wraps existing table into a 300px wide div. You probably will not need to set the width on the wrapping div at all (300px in this example), I have it here so that clipping effect is easily visible. And be nice, don't forget to replace that inline style with a class.

$(document).ready(function() {
var stdTable1 = $(".standard-grid1").dataTable({
    "iDisplayLength": -1,
    "bPaginate": true,
    "iCookieDuration": 60,
    "bStateSave": false,
    "bAutoWidth": false,
    //true
    "bScrollAutoCss": true,
    "bProcessing": true,
    "bRetrieve": true,
    "bJQueryUI": true,
    //"sDom": 't',
    "sDom": '<"H"CTrf>t<"F"lip>',
    "aLengthMenu": [[25, 50, 100, -1], [25, 50, 100, "All"]],
    //"sScrollY": "500px",
    //"sScrollX": "100%",
    "sScrollXInner": "110%",
    "fnInitComplete": function() {
        this.css("visibility", "visible");
    }
});

var tableId = 'PeopleIndexTable';
$('<div style="width: 300px; overflow: auto"></div>').append($('#' + tableId)).insertAfter($('#' + tableId + '_wrapper div').first())});

Quick List: There are a number of common types of setup.exe files. Here are some of them in a "short-list". More fleshed-out details here (towards bottom).

Setup.exe Extract: (various flavors to try)

setup.exe /a
setup.exe /s /extract_all
setup.exe /s /extract_all:[path]
setup.exe /stage_only
setup.exe /extract "C:\My work"
setup.exe /x
setup.exe /x [path]
setup.exe /s /x /b"C:\FolderInWhichMSIWillBeExtracted" /v"/qn"

dark.exe -x outputfolder setup.exe

dark.exe is a WiX binary - install WiX to extract a WiX setup.exe (as of now). More (section 4).

There is always:

setup.exe /?

• Real-world, pragmatic Installshield setup.exe extraction.
• Installshield: Setup.exe and Update.exe Command-Line Parameters.
• Installshield setup.exe commands (sample)
• Wise setup.exe commands
• Advanced Installer setup.exe commands.

MSI Extract: msiexec.exe / File.msi extraction:

 msiexec /a File.msi
 msiexec /a File.msi TARGETDIR=C:\MyInstallPoint /qn

• msiexec.exe command lines.
• Microsoft's msiexec.exe documentation on MSDN.

Many Setup Tools: It is impossible to cover all the different kinds of possible setup.exe files. They might feature all kinds of different command line switches. There are so many possible tools that can be used. (non-MSI,MSI, admin-tools, multi-platform, etc...).

NSIS / Inno: Commmon, free tools such as Inno Setup seem to make extraction hard (unofficial unpacker, not tried by me, run by virustotal.com). Whereas NSIS seems to use regular archives that standard archive software (7-zip et al) can open and extract.

General Tricks: One trick is to launch the setup.exe and look in the 1) system's temp folder for extracted files. Another trick is to use 2) 7-Zip, WinRAR, WinZip or similar archive tools to see if they can read the format. Some claim success by 3) opening the setup.exe in Visual Studio. Not a technique I use. 4) And there is obviously application repackaging - capturing the changes done to a computer after a setup has run and clean it up - requires a special tool (most of the free ones come and go, Advanced Installer Architect and AdminStudio are big players).

UPDATE: A quick presentation of various deployment tools used to create installers: How to create windows installer (comprehensive links).

And a simpler list view of the most used development tools as of now (2018), for quicker reading and overview.

And for safekeeping:

• Create MSI from extracted setup files (towards bottom)
• Regarding silent installation using Setup.exe generated using Installshield 2013 (.issuite) project file (different kinds of Installshield setup.exe files)
• What is the purpose of administrative installation initiated using msiexec /a?.

Just a disclaimer: A setup.exe file can contain an embedded MSI, it can be a legacy style (non-MSI) installer or it can be just a regular executable with no means of extraction whatsoever. The "discussion" below first presents the use of admin images for MSI files and how to extract MSI files from setup.exe files. Then it provides some links to handle other types of setup.exe files. Also see the comments section.

UPDATE: a few sections have now been added directly below, before the description of MSI file extract using administrative installation. Most significantly a blurb about extracting WiX setup.exe bundles (new kid on the block). Remember that a "last resort" to find extracted setup files, is to launch the installer and then look for extracted files in the temp folder (Hold down Windows Key, tap R, type %temp% or %tmp% and hit Enter) - try the other options first though - for reliability reasons.

Apologies for the "generalized mess" with all this heavy inter-linking. I do believe that you will find what you need if you dig enough in the links, but the content should really be cleaned up and organized better.

General links:

• General links for handling different kinds of setup.exe files (towards bottom).
• Uninstall and Install App on my Computer silently (generic, but focus on silent uninstall).
• Similar description of setup.exe files (link for safekeeping - see links to deployment tools).
• A description of different flavors of Installshield setup.exe files (extraction, silent running, etc...)
• Wise setup.exe switches (Wise is no longer on the market, but many setup.exe files remain).

Extract content:

• Extract WiX Burn-built setup.exe (a bit down the page) - also see section directly below.
• Programmatically extract contents of InstallShield setup.exe (Installshield).

Vendor links:

• Advanced Installer setup.exe files.
• Installshield setup.exe files.
• Installshield suite setup.exe files.

WiX Toolkit & Burn Bundles (setup.exe files)

Tech Note: The WiX toolkit now delivers setup.exe files built with the bootstrapper tool Burn that you need the toolkit's own dark.exe decompiler to extract. Burn is used to build setup.exe files that can install several embedded MSI or executables in a specified sequence. Here is a sample extraction command:

dark.exe -x outputfolder MySetup.exe

Before you can run such an extraction, some prerequisite steps are required:

1. Download and install the WiX toolkit (linking to a previous answer with some extra context information on WiX - as well as the download link).
2. After installing WiX, just open a command prompt, CD to the folder where the setup.exe resides. Then specify the above command and press Enter
3. The output folder will contain a couple of sub-folders containing both extracted MSI and EXE files and manifests and resource file for the Burn GUI (if any existed in the setup.exe file in the first place of course).
4. You can now, in turn, extract the contents of the extracted MSI files (or EXE files). For an MSI that would mean running an admin install - as described below.

There is built-in MSI support for file extraction (admin install)

MSI or Windows Installer has built-in support for this - the extraction of files from an MSI file. This is called an administrative installation. It is basically intended as a way to create a network installation point from which the install can be run on many target computers. This ensures that the source files are always available for any repair operations.

Note that running an admin install versus using a zip tool to extract the files is very different! The latter will not adjust the media layout of the media table so that the package is set to use external source files - which is the correct way. Always prefer to run the actual admin install over any hacky zip extractions. As to compression, there are actually three different compression algorithms used for the cab files inside the MSI file format: MSZip, LZX, and Storing (uncompressed). All of these are handled correctly by doing an admin install.

Important: Windows Installer caches installed MSI files on the system for repair, modify and uninstall scenarios. Starting with Windows 7 (MSI version 5) the MSI files are now cached full size to avoid breaking the file signature that prevents the UAC prompt on setup launch (a known Vista problem). This may cause a tremendous increase in disk space consumption (several gigabytes for some systems). To prevent caching a huge MSI file, you should run an admin-install of the package before installing. This is how a company with proper deployment in a managed network would do things, and it will strip out the cab files and make a network install point with a small MSI file and files besides it.

Admin-installs have many uses

It is recommended to read more about admin-installs since it is a useful concept, and I have written a post on stackoverflow: What is the purpose of administrative installation initiated using msiexec /a?.

In essence the admin install is important for:

• Extracting and inspecting the installer files
  • To get an idea of what is actually being installed and where
  • To ensure that the files look trustworthy and secure (no viruses - malware and viruses can still hide inside the MSI file though)
• Deployment via systems management software (for example SCCM)
• Corporate application repackaging
• Repair, modify and self-repair operations
• Patching & upgrades
• MSI advertisement (among other details this involves the "run from source" feature where you can run directly from a network share and you only install shortcuts and registry data)
• A number of other smaller details

Please read the stackoverflow post linked above for more details. It is quite an important concept for system administrators, application packagers, setup developers, release managers, and even the average user to see what they are installing etc...

Admin-install, practical how-to

You can perform an admin-install in a few different ways depending on how the installer is delivered. Essentially it is either delivered as an MSI file or wrapped in an setup.exe file.

Run these commands from an elevated command prompt, and follow the instructions in the GUI for the interactive command lines:

• MSI files:

  msiexec /a File.msi
  

  that's to run with GUI, you can do it silently too:

  msiexec /a File.msi TARGETDIR=C:\MyInstallPoint /qn
  

• setup.exe files:

  setup.exe /a
  

A setup.exe file can also be a legacy style setup (non-MSI) or the dreaded Installscript MSI file type - a well known buggy Installshield project type with hybrid non-standards-compliant MSI format. It is essentially an MSI with a custom, more advanced GUI, but it is also full of bugs.

For legacy setup.exe files the /a will do nothing, but you can try the /extract_all:[path] switch as explained in this pdf. It is a good reference for silent installation and other things as well. Another resource is this list of Installshield setup.exe command line parameters.

MSI patch files (*.MSP) can be applied to an admin image to properly extract its files. 7Zip will also be able to extract the files, but they will not be properly formatted.

Finally - the last resort - if no other way works, you can get hold of extracted setup files by cleaning out the temp folder on your system, launch the setup.exe interactively and then wait for the first dialog to show up. In most cases the installer will have extracted a bunch of files to a temp folder. Sometimes the files are plain, other times in CAB format, but Winzip, 7Zip or even Universal Extractor (haven't tested this product) - may be able to open these.

There is a version conflict between jar/dependency please check all version of spring is same. if you use maven remove version of dependency and use Spring.io dependency.it handle version conflict. Add this in your pom

 <dependency>
            <groupId>io.spring.platform</groupId>
            <artifactId>platform-bom</artifactId>
            <version>2.0.1.RELEASE</version>

Some months ago I ran into an odd situation where I also needed to send some Json-formatted date back to my controller. Here's what I came up with after pulling my hair out:

My class looks like this :

public class NodeDate
{
    public string nodedate { get; set; }
}
public class NodeList1
{
    public List<NodeDate> nodedatelist { get; set; }
}

and my c# code as follows :

        public string getTradeContribs(string Id, string nodedates)
    {            
        //nodedates = @"{""nodedatelist"":[{""nodedate"":""01/21/2012""},{""nodedate"":""01/22/2012""}]}";  // sample Json format
        System.Web.Script.Serialization.JavaScriptSerializer ser = new System.Web.Script.Serialization.JavaScriptSerializer();
        NodeList1 nodes = (NodeList1)ser.Deserialize(nodedates, typeof(NodeList1));
        string thisDate = "";
        foreach (var date in nodes.nodedatelist)
        {  // iterate through if needed...
            thisDate = date.nodedate;
        }   
    }

and so I was able to Deserialize my nodedates Json object parameter in the "nodes" object; naturally of course using the class "NodeList1" to make it work.

I hope this helps.... Bob

You can use my StretchableImageView preserving the aspect ratio (by width or by height) depending on width and height of drawable:

import android.content.Context;
import android.util.AttributeSet;
import android.widget.ImageView;

public class StretchableImageView extends ImageView{

    public StretchableImageView(Context context) {
        super(context);
    }

    public StretchableImageView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public StretchableImageView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        if(getDrawable()!=null){
            if(getDrawable().getIntrinsicWidth()>=getDrawable().getIntrinsicHeight()){
                int width = MeasureSpec.getSize(widthMeasureSpec);
                int height = width * getDrawable().getIntrinsicHeight()
                            / getDrawable().getIntrinsicWidth();
                setMeasuredDimension(width, height);
            }else{
                int height = MeasureSpec.getSize(heightMeasureSpec);
                int width = height * getDrawable().getIntrinsicWidth()
                            / getDrawable().getIntrinsicHeight();
                setMeasuredDimension(width, height);
            }
        }
    }
}

Knowing not to use, and WHY not to use:

SELECT *

With a Microsoft compiler[1], static variables that are not int-like can also be defined in a header file, but outside of the class declaration, using the Microsoft specific __declspec(selectany).

class A
{
    static B b;
}

__declspec(selectany) A::b;

Note that I'm not saying this is good, I just say it can be done.

[1] These days, more compilers than MSC support __declspec(selectany) - at least gcc and clang. Maybe even more.

%08x means that every number should be printed at least 8 characters wide with filling all missing digits with zeros, e.g. for '1' output will be 00000001

What are you using to compile this? If there's an undefined reference error, usually it's because the .o file (which gets created from the .cpp file) doesn't exist and your compiler/build system is not able to link it.

Also, in your card.cpp, the function should be Card::Card() instead of void Card. The Card:: is scoping; it means that your Card() function is a member of the Card class (which it obviously is, since it's the constructor for that class). Without this, void Card is just a free function. Similarly,

void Card(Card::Rank rank, Card::Suit suit)

should be

Card::Card(Card::Rank rank, Card::Suit suit)

Also, in deck.cpp, you are saying #include "Deck.h" even though you referred to it as deck.h. The includes are case sensitive.

Basic Steps to Debug a Procedure in Toad

1. Load your Procedure in Toad Editor.
2. Put debug point on the line where you want to debug.See the first screenshot.
3. Right click on the editor Execute->Execute PLSQL(Debugger).See the second screeshot.
4. A window opens up,you need to select the procedure from the left side and pass parameters for that procedure and then click Execute.See the third screenshot.
5. Now start your debugging check Debug-->Step Over...Add Watch etc.

Reference:Toad Debugger

You can use like bellow:

(( var0 = var1<98?9:21 ))

the same as

if [ "$var1" -lt 98 ]; then
   var0=9
else
   var0=21
fi

extends

condition?result-if-true:result-if-false

I found the interested thing on the book "Advanced Bash-Scripting Guide"

This is really easy using jQuery.

For instance:

$(".left").mouseover(function(){$(".left1").show()});
$(".left").mouseout(function(){$(".left1").hide()});

I've update your fiddle: http://jsfiddle.net/TqDe9/2/

well, there are many ways to do this in javascript just like other says. I don't think there's a way to do it in react. here's what I would do:

in a js file:

module.exports = {
    small_square: 's',
    large_square: 'q'
}

in your react file:

'use strict';

var Constant = require('constants');
....
var something = Constant.small_square;

something for you to consider, hope this helps

Python 3

from urllib.error import HTTPError

Python 2

from urllib2 import HTTPError

Just catch HTTPError, handle it, and if it's not Error 404, simply use raise to re-raise the exception.

See the Python tutorial.

e.g. complete example for Pyhton 2

import urllib2
from urllib2 import HTTPError
try:
   urllib2.urlopen("some url")
except HTTPError as err:
   if err.code == 404:
       <whatever>
   else:
       raise

in my own case in django 1.10.1 running on python2.7.11, I was trying to start the server using django-admin runserver instead of manage.py runserver in my project directory.

Also, (related) check the order of your handler mappings. We had a .ashx with a .svc (e.g. /foo.asmx/bar.svc/path) in the path after it. The .svc mapping was first so 404 for the .svc path which matched before the .asmx. Havn't thought too much but maybe url encodeing the path would take care of this.

Your problem has nothing to do with encodings, it's a simple matter of understanding basic C++. You are returning a pointer to a local variable from your function, which will have gone out of scope by the time anyone can use it, thus creating undefined behaviour (i.e. a programming error).

Follow this Golden Rule: "If you are using naked char pointers, you're Doing It Wrong. (Except for when you aren't.)"

I've previously posted some code to do the conversion and communicating the input and output in C++ std::string and std::wstring objects.

[root@localhost administrador]# yum search mysql | grep client
community-mysql.i686 : MySQL client programs and shared libraries
                            : client
community-mysql-libs.i686 : The shared libraries required for MySQL clients
root-sql-mysql.i686 : MySQL client plugin for ROOT
mariadb-libs.i686 : The shared libraries required for MariaDB/MySQL clients
[root@localhost administrador]# yum install  -y community-mysql

Go for whatever is most readable and easily maintainable. Just because you can write it out in a single line doesn't mean that you should. Your existing solution is close to what I would use other than I would user iteritems to skip the value lookup, and I hate nested ifs if I can avoid them:

for key, val in d.iteritems():
    if filter_string not in key:
        continue
    # do something

However if you realllly want something to let you iterate through a filtered dict then I would not do the two step process of building the filtered dict and then iterating through it, but instead use a generator, because what is more pythonic (and awesome) than a generator?

First we create our generator, and good design dictates that we make it abstract enough to be reusable:

# The implementation of my generator may look vaguely familiar, no?
def filter_dict(d, filter_string):
    for key, val in d.iteritems():
        if filter_string not in key:
            continue
        yield key, val

And then we can use the generator to solve your problem nice and cleanly with simple, understandable code:

for key, val in filter_dict(d, some_string):
    # do something

In short: generators are awesome.

Put a single listener on the table. When it gets a click from an input with a button that has a name of "edit" and value "edit", change its value to "modify". Get rid of the input's id (they aren't used for anything here), or make them all unique.

<script type="text/javascript">

function handleClick(evt) {
  var node = evt.target || evt.srcElement;
  if (node.name == 'edit') {
    node.value = "Modify";
  }
}

</script>

<table id="table1" border="1" onclick="handleClick(event);">
    <thead>
      <tr>
          <th>Select
    </thead>
    <tbody>
       <tr> 
           <td>
               <form name="f1" action="#" >
                <input id="edit1" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f2" action="#" >
                <input id="edit2" type="submit" name="edit" value="Edit">
               </form>
       <tr> 
           <td>
               <form name="f3" action="#" >
                <input id="edit3" type="submit" name="edit" value="Edit">
               </form>

Tested as working:

param([Int32]$step=30) 

$iTunes = New-Object -ComObject iTunes.Application

Well, you might look at System.Threading.Semaphore class. Other than that - no, you have to make this yourself. AFAIK there is no such built-in collection.

If you don't want to modify the Makefile itself, you can use --eval to add a new target, and then execute the new target, e.g.

make --eval='print-tests: @echo TESTS $(TESTS) ' print-tests

You can insert the required TAB character in the command line using CTRL-V, TAB

example Makefile from above:

all: do-something

TESTS=
TESTS+='a'
TESTS+='b'
TESTS+='c'

do-something:
        @echo "doing something"
        @echo "running tests $(TESTS)"
        @exit 1

A good answer already, but there are a couple of other ways to do this:

unique(c[c%in%a[a%in%b]])

or,

tst <- c(unique(a),unique(b),unique(c))
tst <- tst[duplicated(tst)]
tst[duplicated(tst)]

You can obviously omit the unique calls if you know that there are no repeated values within a, b or c.

Another alternative

char[] c = { 'R', 'o', 'c', 'k', '-', '&', '-', 'R', 'o', 'l', 'l' };
string s = String.Concat( c );

Debug.Assert( s.Equals( "Rock-&-Roll" ) );

I'm running into the same issue with one of my own apps. So far I've found the only non-deprecated way to access Google News data is through their RSS feeds. They have a feed for each section and also a useful search function. However, these are only for noncommercial use.

As for viable alternatives I'll be trying out these two services: Feedzilla, Daylife

Default value for parameters are evaluated at "compilation", once. So obviously you can't access self. The classic example is list as default parameter. If you add elements into it, the default value for the parameter changes!

The workaround is to use another default parameter, typically None, and then check and update the variable.

This will work for MySQL, Postgres, and probably any other PDO driver that uses the LIMIT clause.

Notice LIMIT 0 is added for improved performance:

$rs = $db->query('SELECT * FROM my_table LIMIT 0');
for ($i = 0; $i < $rs->columnCount(); $i++) {
    $col = $rs->getColumnMeta($i);
    $columns[] = $col['name'];
}
print_r($columns);

This is for InfluxDB shell version: 1.8.2

Delete works without time field too. As you can see from the series of screen shots:

1. I create a DB and and add start using it.

2. Add some rows in it.Verify if they are added.

3. Delete all with tag 'Dev1' and verify the same.

Note: The tag name has to be in single quotes only. Not double.

Here is another most easy way to get a custom shape for your image (Image View). It may be helpful for someone. It's just a single line code.

First you need to add a dependency:

dependencies {
    compile 'com.mafstech.libs:mafs-image-shape:1.0.4'   
}

And then just write a line of code like this:

Shaper.shape(context, 
       R.drawable.your_original_image_which_will_be_displayed, 
       R.drawable.shaped_image_your_original_image_will_get_this_images_shape,
       imageView,
       height, 
       weight);   

If you don't like the prototype approach, because it doesn't really behave in a nice OOP-way, you could try this:

var BaseClass = function() 
{
    this.some_var = "foobar";

    /**
     * @return string
     */
    this.someMethod = function() {
        return this.some_var;
    }
};

var MyClass = new Class({ extends: BaseClass }, function()
{
    /**
     * @param string value
     */
    this.__construct = function(value)
    {
        this.some_var = value;

(I encountered the identical issue. After many tries I SOLVED it and located the MY ROOT CAUSE. I keep my try path here but you can skip to the end if you want.)

I want to point it out that BE VERY CAREFUL WITH enden's solution 2. Some other programs may cache installation packages in the C:\ProgramData\Pacakges Cache folder. If you remove data from that folder, you may jeopardize other programs installation/uninstallation.

I encountered this multiple failures during install VS2015. And after I remove all the content from the C:\ProgramData\Pacakges Cache, both my VS2013 and VS2015 stuck in the Programs and Features window and I cannot change/repair/uninstall them.

To fix the change/repair/uninstall failure, I have to go to below 2 registry keys:

First of all: BACKUP YOUR REGISTRY BEFORE YOU DO ANYTHING TO IT.

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall]

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall]

And remove every key whose InstallLocation points to the C:\ProgramData\Pacakges Cache AND whose DispalyName looks related to Visual Studio 2013/2015 (this may requrie some experience/intuition).

Then, the stuck items of VS2013/2015 in Program & Features window are gone. And now I am able to re-install the VS2013.

But I still cannot install VS2015 with the installer. The error is still as below:

But at least I can change/repair/uninstall VS2015 in the Prgram & Features window. So I choose to repair it. But the repair doesn't work. I still got the same error as above.

Then I uninstalled the failed VS2015 and tried to repair the VC++2015 redist as said in TimVdG's marked answer. And then reinstall VS2015 with the installer.

Still failed.

Then I tried Brian Swart's solution to install VS2015 without Update 1. But it still failed with TeamExplorer. I checked the log and found this:

MSI (s) (48:A0) [14:53:34:997]: Windows Installer installed the product. Product Name: Team Explorer for Microsoft Visual Studio 2015. Product Version: 14.0.23102. Product Language: 1033. Manufacturer: Microsoft Corporation. Installation success or error status: 1603.

And I googled a bit about 1603 error. Now I am trying to add full control to the C:\Program Files (x86)\Microsoft Visual Studio 14.0 folder and try again.

Still doesn't work.

=========> The Final Solution <=========

So in my scenario, it has nothing to do with the VC2015 redistributables.

My root cause is the incorrect .NET version number in the registry.

On a 64bit Windows, .NET version is stored in 2 places in registry:

HKLM\Software\Microsoft\NET Framework Setup\NDP\v4\Full\Version

HKEY_LOCAL_MACHINE\SOFTWARE**WOW6432Node**\Microsoft\NET Framework Setup\NDP\v4\Full\Version

Below is what my box has:

Note that leading character v in the Version? I don't know who put it there. But once I removed it, my VS2015 with Update 3 can be installed smoothly!

So you may wonder how could I find this. Well, since I couldn't install VS2015, I turned to VS2017. But after intalled VS2017 successfully, I couldn't launch it. It says this:

So I decided to check the installed .NET version and saw the interesting difference above. Once I removed the leading v, VS2017 can be started.

But anyway, I still don't know who put the v there... Shame on it!

Last but not the least: Please also make sure the Release, Version registry key value are consistent and can work with your Windows version. Refer to below:

.NET and Windows version dependencies.

how to determine the installed .NET version.

Windows 10 version info

Add some more findings:

After I finished this install sequence: VS2017 -> VS2015 -> VS2013, I noticed that there's even no VC++2015 redist on my box:

Because both VC++ 2015 and VC++2017 redists are 14.xxx. So having the higher version is enough. When I try to manually install VC++ 2015 redist, it says this:

I had this error- it happened because my password expired and I had to change it. I didn't notice it, because in some programs I could still log in and everything would work normally (including windows), but I couldn't log to any sql servers.

li{
    margin-left:50px;
}

or replace 50px with whatever you want.

If you want every cell in the grid to have the same background color, you can just do this:

dataGridView1.DefaultCellStyle.BackColor = Color.Green;

You can also use:

Dim strPath As String = AppDomain.CurrentDomain.BaseDirectory

@FindBy(xpath = "//button[@class='btn btn-primary' and contains(text(), 'Submit')]") private WebElementFacade submitButton;

public void clickOnSubmitButton() {
    submitButton.click();
}   

Exec the query in TOAD or SQL DEVELOPER

---select /*csv*/ username, user_id, created from all_users;

Save in .SQL format in "C" drive

--- x.sql

execute command

---- set serveroutput on
     spool y.csv
     @c:\x.sql
     spool off;

I'll suggest that you use this as it will check for both single and multiple occurrence of white space (as suggested by Lucas Green).

$journalName = preg_replace('/\s+/', '_', $journalName);

instead of:

$journalName = str_replace(' ', '_', $journalName);

The easiest might be:

Array(1, 2, 3) :+ 4

Actually, Array can be implcitly transformed in a WrappedArray

If you haven't created the form and want to change the queryset you can do:

formmodel.base_fields['myfield'].queryset = MyModel.objects.filter(...)

This is pretty useful when you are using generic views!

Set the MAVEN_OPTS. It should work !!

export MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n"

mvn spring-boot:run -Dserver.port=8090

When I was bugged with this, I got the serializing solution where, you can serialize your string, But I came up with a hack as well.

Read this only if you haven't read about serializing, else go down and read my hack

In order to store array items in order, we can serialize the array into a single string (by making a new class ObjectSerializer (copy the code from – www.androiddevcourse.com/objectserializer.html , replace everything except the package name))

Entering data in Shared preference :

the rest of the code on line 38 -

Put the next arg as this, so that if data is not retrieved it will return empty array(we cant put empty string coz the container/variable is an array not string)

Coming to my Hack :-

Merge contents of array into a single string by having some symbol in between each item and then split it using that symbol when retrieving it. Coz adding and retrieving String is easy with shared preferences. If you are worried about splitting just look up "splitting a string in java".

[Note: This works fine if the contents of your array is of primitive kind like string, int, float, etc. It will work for complex arrays which have its own structure, suppose a phone book, but the merging and splitting would become a bit complex. ]

PS: I am new to android, so don't know if it is a good hack, so lemme know if you find better hacks.

There were interesting answers but I didn't seem to find one to match my needs, the closest being from @chittrang-mishra which refers only to one specific function and not several toggles as in my app.

I did not want to use [hidden] to take advantage of *ngIf not even being a part of the DOM so I found the following solution which may not be the best for all as it suppresses the error instead of correcting it, but in my case where I know the final result is correct, it seems ok for my app.

What I did was implement AfterViewChecked, add constructor(private changeDetector : ChangeDetectorRef ) {} and then

ngAfterViewChecked(){
  this.changeDetector.detectChanges();
}

I hope this helps other as many others have helped me.

There are (at least) two different ways to get to theWorksheet object

• via the Sheets or Worksheets collections as referenced by DanM
• by unqualified object names

When a new workbook with three worksheets is created there will exist four objects which you can access via unqualified names: ThisWorkbook; Sheet1; Sheet2; Sheet3. This lets you write things like this:

Sheet1.Range("A1").Value = "foo"

Although this may seem like a useful shortcut, the problem comes when the worksheets are renamed. The unqualified object name remains as Sheet1 even if the worksheet is renamed to something totally different.

There is some logic to this because:

• worksheet names don't conform to the same rules as variable names
• you might accidentally mask an existing variable

For example (tested in Excel 2003), create a new Workbook with three worksheets. Create two modules. In one module declare this:

Public Sheet4 As Integer

In the other module put:

Sub main()

Sheet4 = 4

MsgBox Sheet4

End Sub

Run this and the message box should appear correctly.

Now add a fourth worksheet to the workbook which will create a Sheet4 object. Try running main again and this time you will get an "Object does not support this property or method" error

You're looking for the function strcmp, or strncmp from string.h.

Since strings are just arrays, you need to compare each character, so this function will do that for you:

if (strcmp(favoriteDairyProduct, "cheese") == 0)
{
    printf("You like cheese too!");
}
else
{
    printf("I like cheese more.");
}

Starting with matplotlib 1.4.0 there is now an an interactive backend for use in the notebook

%matplotlib notebook

There are a few version of IPython which do not have that alias registered, the fall back is:

%matplotlib nbagg

If that does not work update you IPython.

To play with this, goto tmpnb.org

and paste

%matplotlib notebook

import pandas as pd
import numpy as np
import matplotlib

from matplotlib import pyplot as plt
import seaborn as sns

ts = pd.Series(np.random.randn(1000), index=pd.date_range('1/1/2000', periods=1000))
ts = ts.cumsum()

df = pd.DataFrame(np.random.randn(1000, 4), index=ts.index,
                  columns=['A', 'B', 'C', 'D'])
df = df.cumsum()
df.plot(); plt.legend(loc='best')    

into a code cell (or just modify the existing python demo notebook)

Multiply by 1000, round, and divide back by 1000.

The best way to do it would be to submit the contents of the div to the server and open a new window where the server could put those contents into the new window.

If that's not an option you can try to use a client-side language like javascript to hide everything on the page except that div and then print the page...

Label without an onclick will behave as you would expect. It changes the input. What you relly want is to execute selectAll() when you click on a label, right? Then only add select all to the label onclick. Or wrap the input into the the label and assign onclick only for the label

<label for="check_all_1" onclick="selectAll(document.wizard_form, this);">
  <input type="checkbox" id="check_all_1" name="check_all_1" title="Select All">
  Select All
</label>

That would be:

b.rstrip('\n')

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

a.read().splitlines()

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

There is really quite a number of ways to do this and all of the above are in one way or another valid approaches... Let me add a straightforward proposition. So assuming your current existing json file looks is this....

{
     "name":"myname"
}

And you want to bring in this new json content (adding key "id")

{
     "id": "134",
     "name": "myname"
 }

My approach has always been to keep the code extremely readable with easily traceable logic. So first, we read the entire existing json file into memory, assuming you are very well aware of your json's existing key(s).

import json 

# first, get the absolute path to json file
PATH_TO_JSON = 'data.json' #  assuming same directory (but you can work your magic here with os.)

# read existing json to memory. you do this to preserve whatever existing data. 
with open(PATH_TO_JSON,'r') as jsonfile:
    json_content = json.load(jsonfile) # this is now in memory! you can use it outside 'open'

Next, we use the 'with open()' syntax again, with the 'w' option. 'w' is a write mode which lets us edit and write new information to the file. Here s the catch that works for us ::: any existing json with the same target write name will be erased automatically.

So what we can do now, is simply write to the same filename with the new data

# add the id key-value pair (rmbr that it already has the "name" key value)
json_content["id"] = "134"

with open(PATH_TO_JSON,'w') as jsonfile:
    json.dump(json_content, jsonfile, indent=4) # you decide the indentation level

And there you go! data.json should be good to go for an good old POST request

Here is a functional approach using map, itertools.repeat and operator.mul:

import operator
from itertools import repeat


def scalar_multiplication(vector, scalar):
    yield from map(operator.mul, vector, repeat(scalar))

Example of usage:

>>> v = [1, 2, 3, 4]
>>> c = 3
>>> list(scalar_multiplication(v, c))
[3, 6, 9, 12]

This worked for me git describe --tags --abbrev=0

Edit 2020: As mentioned by some of the comments below, this might, or might not work for you, so be careful!

I try this same method, but with a different list with more values in the function map. My problem was to forget a return statement. This is very important :)

 bottom: new TabBar(
      controller: _controller,
      isScrollable: true,
      tabs:
        moviesTitles.map((title) { return Tab(text: title)}).toList()
      ,
    ),

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

Rather than rolling your own, the most reliable way to tell if an in-built type is numeric is probably to reference Microsoft.VisualBasic and call Information.IsNumeric(object value). The implementation handles a number of subtle cases such as char[] and HEX and OCT strings.

You can create a function with the pattern ShouldSerialize{PropertyName} which tells the XmlSerializer if it should serialize the member or not.

For example, if your class property is called MyNullableInt you could have

public bool ShouldSerializeMyNullableInt() 
{
  return MyNullableInt.HasValue;
}

Here is a full sample

public class Person
{
  public string Name {get;set;}
  public int? Age {get;set;}
  public bool ShouldSerializeAge()
  {
    return Age.HasValue;
  }
}

Serialized with the following code

Person thePerson = new Person(){Name="Chris"};
XmlSerializer xs = new XmlSerializer(typeof(Person));
StringWriter sw = new StringWriter();
xs.Serialize(sw, thePerson);

Results in the followng XML - Notice there is no Age

<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <Name>Chris</Name>
</Person>

A much easier solution: Using a dynamic type

As of Json.NET 4.0 Release 1, there is native dynamic support. You don't need to declare a class, just use dynamic :

dynamic jsonDe = JsonConvert.DeserializeObject(json);

All the fields will be available:

foreach (string typeStr in jsonDe.Type[0])
{
    // Do something with typeStr
} 

string t = jsonDe.t;
bool a = jsonDe.a;
object[] data = jsonDe.data;
string[][] type = jsonDe.Type;

With dynamic you don't need to create a specific class to hold your data.

In Excel 2010, You have the countifS function.

I was having issues if I was trying to count the number of cells in a range that have a non0 value.

e.g. If you had a worksheet that in the range A1:A10 had values 1, 0, 2, 3, 0 and you wanted the answer 3.

The normal function =COUNTIF(A1:A10,"<>0") would give you 8 as it is counting the blank cells as 0s.

My solution to this is to use the COUNTIFS function with the same range but multiple criteria e.g.

=COUNTIFS(A1:A10,"<>0",A1:A10,"<>")

This effectively checks if the range is non 0 and is non blank.

The limitation relates to the simplified CommonJS syntax vs. the normal callback syntax:

• http://requirejs.org/docs/whyamd.html#commonjscompat
• https://github.com/jrburke/requirejs/wiki/Differences-between-the-simplified-CommonJS-wrapper-and-standard-AMD-define

Loading a module is inherently an asynchronous process due to the unknown timing of downloading it. However, RequireJS in emulation of the server-side CommonJS spec tries to give you a simplified syntax. When you do something like this:

var foomodule = require('foo');
// do something with fooModule

What's happening behind the scenes is that RequireJS is looking at the body of your function code and parsing out that you need 'foo' and loading it prior to your function execution. However, when a variable or anything other than a simple string, such as your example...

var module = require(path); // Call RequireJS require

...then Require is unable to parse this out and automatically convert it. The solution is to convert to the callback syntax;

var moduleName = 'foo';
require([moduleName], function(fooModule){
    // do something with fooModule
})

Given the above, here is one possible rewrite of your 2nd example to use the standard syntax:

define(['dyn_modules'], function (dynModules) {
    require(dynModules, function(){
        // use arguments since you don't know how many modules you're getting in the callback
        for (var i = 0; i < arguments.length; i++){
            var mymodule = arguments[i];
            // do something with mymodule...
        }
    });

});

EDIT: From your own answer, I see you're using underscore/lodash, so using _.values and _.object can simplify the looping through arguments array as above.

The #define is part of the preprocessor language for C and C++. When they're used in code, the compiler just replaces the #define statement with what ever you want. For example, if you're sick of writing for (int i=0; i<=10; i++) all the time, you can do the following:

#define fori10 for (int i=0; i<=10; i++)

// some code...

fori10 {
    // do stuff to i
}

If you want something more generic, you can create preprocessor macros:

#define fori(x) for (int i=0; i<=x; i++)
// the x will be replaced by what ever is put into the parenthesis, such as
// 20 here
fori(20) {
    // do more stuff to i
}

It's also very useful for conditional compilation (the other major use for #define) if you only want certain code used in some particular build:

// compile the following if debugging is turned on and defined
#ifdef DEBUG
// some code
#endif

Most compilers will allow you to define a macro from the command line (e.g. g++ -DDEBUG something.cpp), but you can also just put a define in your code like so:

#define DEBUG

Some resources:

1. Wikipedia article
2. C++ specific site
3. Documentation on GCC's preprocessor
4. Microsoft reference
5. C specific site (I don't think it's different from the C++ version though)

As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)

Duration column = End - Start

1. Once done, plot your stacked bar chart using the entire data.
2. Mark start and end range to no fill.
3. Right click on the X Axis and change Axis options manually. (This did cause me some issues, till I realized I couldn't manipulate them to enter dates, :) yeah I am newbie, excel masters! :))

Calendar cal = Calendar.getInstance(); 
cal.add(Calendar.MONTH, 1);
java.util.Date dt = cal.getTime();

you can convert to array so get object name

var objs = [
      {name: "Joe", age: 22},
      {name: "Kevin", age: 24},
      {name: "Peter", age: 21}
    ];
document.body.innerHTML = Object.values(objs).map(function(obj){
   return obj.name;
});

You can indeed align the box to the bottom without using position:absolute if you know the height of the #container using the text alignment feature of inline-block elements.

Here you can see it in action.

This is the code:

#container {
    /* So the #container most have a fixed height */
    height: 300px;
    line-height: 300px;
    background:Red;
}

#container > * {
    /* Restore Line height to Normal */
    line-height: 1.2em;
}

#copyright {
    display:inline-block;
    vertical-align:bottom;
    width:100%; /* Let it be a block */
    background:green;
}

Here is PostgreSQL example without trigger if someone need it on PostgreSQL:

CREATE SEQUENCE messages_seq;

 CREATE TABLE IF NOT EXISTS messages (
    id CHAR(20) NOT NULL DEFAULT ('message_' || nextval('messages_seq')),
    name CHAR(30) NOT NULL,
);

ALTER SEQUENCE messages_seq OWNED BY messages.id;

I had problems with this recently, i use this code and work fine for me.

var data = 'Peter';

db.User.find({'name' : new RegExp(data, 'i')}, function(err, docs){
    cb(docs);
});

Use directly /Peter/i work, but i use '/'+data+'/i' and not work for me.

In case someone gets similar issues, I had such an issue while inflating the view:

View.inflate(getApplicationContext(), R.layout.my_layout, null)

fixed by replacing getApplicationContext() with this

Verify that you can start your application like that:

java -cp myjarfile.jar snake.Controller

I just read when I double click on it - this sounds like a configuration issue with your operating system. You're double-clicking the file on a windows explorer window? Try to run it from a console/terminal with the command

java -jar myjarfile.jar

The manifest has to end with a new line. Please check your file, a missing new line will cause trouble.

I feel like this has been well covered, maybe except for the following:

• Simple KEY / INDEX (or otherwise called SECONDARY INDEX) do increase performance if selectivity is sufficient. On this matter, the usual recommendation is that if the amount of records in the result set on which an index is applied exceeds 20% of the total amount of records of the parent table, then the index will be ineffective. In practice each architecture will differ but, the idea is still correct.

• Secondary Indexes (and that is very specific to mysql) should not be seen as completely separate and different objects from the primary key. In fact, both should be used jointly and, once this information known, provide an additional tool to the mysql DBA: in Mysql, indexes embed the primary key. It leads to significant performance improvements, specifically when cleverly building implicit covering indexes such as described there.

• If you feel like your data should be UNIQUE, use a unique index. You may think it's optional (for instance, working it out at application level) and that a normal index will do, but it actually represents a guarantee for Mysql that each row is unique, which incidentally provides a performance benefit.

• You can only use FULLTEXT (or otherwise called SEARCH INDEX) with Innodb (In MySQL 5.6.4 and up) and Myisam Engines

• You can only use FULLTEXT on CHAR, VARCHAR and TEXT column types

• FULLTEXT index involves a LOT more than just creating an index. There's a bunch of system tables created, a completely separate caching system and some specific rules and optimizations applied. See http://dev.mysql.com/doc/refman/5.7/en/fulltext-restrictions.html and http://dev.mysql.com/doc/refman/5.7/en/innodb-fulltext-index.html

I have what i think is a better solution, since it is scalable to more levels, as many as wanted, not only two or three.

I use borders, but it can also be done with whateever style wanted, like background-color.

With the border, the idea is to:

• Have a different border color only one div, the div over where the mouse is, not on any parent, not on any child, so it can be seen only such div border in a different color while the rest stays on white.

If you are using javac to compile, and you get this error, then remove all the .class files

rm *.class     # On Unix-based systems

and recompile.

javac fileName.java

slice works just fine in IE and other browsers, it's part of the specification and it's the most efficient method too:

alert("xxx_456".slice(-3));
//-> 456

You have to use the android:hint attribute

<EditText
android:id="@+id/message"
android:hint="<<Your placeholder>>"
/>

In Android Studio, you can switch from XML -> Design View and click on the Component in the layout, the EditText field in this case. This will show all the applicable attributes for that GUI component. This will be handy when you don't know about all the attributes that are there.

You would be surprised to see that EditText has more than 140 attributes for customization.

For files that are not different, any method will require having read both files entirely, even if the read was in the past.

There is no alternative. So creating hashes or checksums at some point in time requires reading the whole file. Big files take time.

File metadata retrieval is much faster than reading a large file.

So, is there any file metadata you can use to establish that the files are different? File size ? or even results of the file command which does just read a small portion of the file?

File size example code fragment:

  ls -l $1 $2 | 
  awk 'NR==1{a=$5} NR==2{b=$5} 
       END{val=(a==b)?0 :1; exit( val) }'

[ $? -eq 0 ] && echo 'same' || echo 'different'  

If the files are the same size then you are stuck with full file reads.

Yes strings must be quoted and in some cases like in applescript, quotes must be escaped

do JavaScript "document.querySelector('span[" & attrName & "=\"" & attrValue & "\"]').click();"

An example with for loop (I prefer List Comprehensions).

a, b = '[br]', '<br />'
for i, v in enumerate(words):
    if a in v:
        words[i] = v.replace(a, b)
print(words)
# ['how', 'much', 'is<br/>', 'the', 'fish<br/>', 'no', 'really']

None of the above answers satisfied me. I found the best solution is to include a hidden input before each checkbox input with the same name.

<input type="hidden" name="foo[]" value="off"/>

<input type="checkbox" name="foo[]"/>

Then on the server side, using a little algorithm you can get something more like HTML should provide.

function checkboxHack(array $checkbox_input): array
{
    $foo = [];
    foreach($checkbox_input as $value) {
        if($value === 'on') {
            array_pop($foo);
        }
        $foo[] = $value;
    }
    return $foo;
}

This will be the raw input

array (
    0 => 'off',
    1 => 'on',
    2 => 'off',
    3 => 'off',
    4 => 'on',
    5 => 'off',
    6 => 'on',
),

And the function will return

array (
    0 => 'on',
    1 => 'off',
    2 => 'on',
    3 => 'on',
)  

For a pure Ruby solution combine URI.parse with CGI.parse (this can be used even if Rails/Rack etc. are not required):

CGI.parse(URI.parse(url).query) 
# =>  {"name1" => ["value1"], "name2" => ["value1", "value2", ...] }

For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.

The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.

That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:

var table = $('#example').DataTable();
  table.rows.add( $(
          '<tr>'+
          '  <td>Tiger Nixon</td>'+
          '  <td>System Architect</td>'+
          '  <td>Edinburgh</td>'+
          '  <td>61</td>'+
          '  <td>2011/04/25</td>'+
          '  <td>$3,120</td>'+
          '</tr>'
  ) ).draw();

The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.

If one assumes he really needs regexp - which is perfectly reasonable in many contexts - the problem is that the specific regexp variety needs to be specified. For example:

egrep '^(100|[1-9]|[1-9][0-9])$'
grep -E '^(100|[1-9]|[1-9][0-9])$'

work fine if the (...|...) alternative syntax is available. In other contexts, they'd be backslashed like \(...\|...\)

Perhaps consider using a preprocessor macro definition instead:

#define UPDATE_ID(instance, id)  ({ (instance)->id= (id); })
#define UPDATE_ROUTE(instance, route)  ({ (instance)->route = (route); })
#define UPDATE_BACKUP_ROUTE(instance, route)  ({ (instance)->backup_route = (route); })
#define UPDATE_CURRENT_ROUTE(instance, route)  ({ (instance)->current_route = (route); })

If your instance of (struct foo) is global, then you don't need the parameter for that of course. But I'm assuming you probably have more than one instance. Using the ({ ... }) block is a GNU-ism that that applies to GCC; it is a nice (safe) way to keep lines together as a block. If you later need to add more to the macros, such as range validation checking, you won't have to worry about breaking things like if/else statements and so forth.

This is what I would do, based upon the requirements you indicated. Situations like this are one of the reasons that I started using python a lot; handling default parameters and such becomes a lot simpler than it ever is with C. (I guess that's a python plug, sorry ;-)

I had to install IIS Media Services 4.1 from the Windows Web App Gallery.

http://www.microsoft.com/web/gallery/install.aspx?appsxml=http://www.microsoft.com/web/webpi/3.0/MediaProductList.xml&appid=MediaServices

Try to delete that "angular/cli": "1.0.0-beta.28.3", in the devDependencies it is useless , and add instead of it "@angular/compiler-cli": "^2.3.1", (since it is the current version, else add it by npm i --save-dev @angular/compiler-cli ), then in your root app folder run those commands:

1. rm -r node_modules (or delete your node_modules folder manually)
2. npm cache clean (npm > v5 add --force so: npm cache clean --force)
3. npm install

In my case it helped to reset the WinForms Toolbox.

I got the exception when opening a Form in the designer; however, compiling and running the code was possible and the code behaved as expected. The exception occurred in a local UserControl implementing an interface from one of my referenced libraries. The error emerged after this library was updated.

This UserControl was listed in the WinForms Toolbox. Probably Visual Studio kept a reference on an outdated version of the library or was caching an outdated version somewhere.

Here is how I recovered from this situation:

1. Right click on the WinForms Toolbox and click on Reset Toolbox in the context menu. (This removes custom items from the Toolbox).
   In my case the Toolbox items were restored to their default state; however, the Pointer-arrow was missing in the Toolbox.
2. Close Visual Studio.
   In my case Visual Studio terminated with a violation exception and aborted.
3. Restart Visual Studio.
   Now everything is running smoothly.

Not very clean but it works :)

Dim arr As Integer() = {1, 2, 3}
Dim newItem As Integer = 4

arr = arr.Concat({newItem}).ToArray

In my rails (rails 4.2) project, I use

Model.last(10) # get the last 10 record order by id

and it works.

>>> for i in range(1, 11):
...     print(i, end=' ')
...     if i==len(range(1, 11)): print()
... 
1 2 3 4 5 6 7 8 9 10 
>>> 

This is how to do it so that the printing does not run behind the prompt on the next line.

This solution doesn't need web.config file changes or catch-all routes.

First, create a controller like this;

public class ErrorController : Controller
{
    public ActionResult Index()
    {
        ViewBag.Title = "Regular Error";
        return View();
    }

    public ActionResult NotFound404()
    {
        ViewBag.Title = "Error 404 - File not Found";
        return View("Index");
    }
}

Then create the view under "Views/Error/Index.cshtml" as;

 @{
      Layout = "~/Views/Shared/_Layout.cshtml";
  }                     
  <p>We're sorry, page you're looking for is, sadly, not here.</p>

Then add the following in the Global asax file as below:

protected void Application_Error(object sender, EventArgs e)
{
        // Do whatever you want to do with the error

        //Show the custom error page...
        Server.ClearError(); 
        var routeData = new RouteData();
        routeData.Values["controller"] = "Error";

        if ((Context.Server.GetLastError() is HttpException) && ((Context.Server.GetLastError() as HttpException).GetHttpCode() != 404))
        {
            routeData.Values["action"] = "Index";
        }
        else
        {
            // Handle 404 error and response code
            Response.StatusCode = 404;
            routeData.Values["action"] = "NotFound404";
        } 
        Response.TrySkipIisCustomErrors = true; // If you are using IIS7, have this line
        IController errorsController = new ErrorController();
        HttpContextWrapper wrapper = new HttpContextWrapper(Context);
        var rc = new System.Web.Routing.RequestContext(wrapper, routeData);
        errorsController.Execute(rc);

        Response.End();
}

If you still get the custom IIS error page after doing this, make sure the following sections are commented out(or empty) in the web config file:

<system.web>
   <customErrors mode="Off" />
</system.web>
<system.webServer>   
   <httpErrors>     
   </httpErrors>
</system.webServer>

.class targets the following element:

<div class="class"></div>

#class targets the following element:

<div id="class"></div>

Note that the id MUST be unique throughout the document, whilst any number of elements may share a class.

Another veneration of find_elements_by_xpath(".//*") is:

from selenium.webdriver.common.by import By


find_elements(By.XPATH, ".//*")

 <div class="form-group">
         <script type="text/javascript"> 
              function activa(){                                                            
                 if(v==0)
                     document.formulario.vr_negativo.disabled = true; 
                 else if(v==1)

                 else if(v==4)
                      document.formulario.vr_negativo.disabled = true; 
                 else if(v==5)
                      document.formulario.vr_negativo.disabled = true; 
                 else if(v==6)
                      document.formulario.vr_negativo.disabled = false;}

Do it in simple. According to documentation https://developer.android.com/training/data-storage/files

String imageName = "IMG_" + String.valueOf(System.currentTimeMillis()) +".jpg";
        picFile = new File(ProfileActivity.this.getCacheDir(),imageName);

and delete it after usage

picFile.delete()

Adding onto Valentin Kuzub's answer above:

we could use a single method that supports providing nth precision number:

public static bool EqualsNthDigitPrecision(this double value, double compareTo, int precisionPoint) =>
    Math.Abs(value - compareTo) < Math.Pow(10, -Math.Abs(precisionPoint));

Note: This method is built for simplicity without added bulk and not with performance in mind.

//To Find Max and Min value in an array without sorting in java

import java.util.Scanner;
import java.util.*;
public class MaxMin_WoutSort {
 public static void main(String args[])
   {
      int n,max=Integer.MIN_VALUE,min=Integer.MAX_VALUE;
      System.out.println("Enter the number of elements: ");
      Scanner sc = new Scanner(System.in);

      int[] arr = new int[sc.nextInt()]; //U can't say static or dynamic.
                                         //UnWrapping object sc to int value;sc.nextInt()
      System.out.println("Enter the elements: ");
      for(int i=0;i<arr.length;i++)      //Loop for entering values in array
      {
          int next = sc.nextInt();
          arr[i] = next;
      }
      for(int j=0;j<arr.length;j++)
     {
          if(arr[j]>max)               //Maximum Condition
            max = arr[j];
          else if(arr[j]<min)         //Minimum Condition
              min = arr[j];
     }
     System.out.println("Highest Value in array: " +max);
     System.out.println("Smallest Value in array: "+min);

 }
}

With Dedexer, you can disassemble the .dex file into dalvik bytecode (.ddx).

Decompiling towards Java isn't possible as far as I know.
You can read about dalvik bytecode here.

I got the following UIAlertView initialization code to compile without errors (I thing the last, varyadic part is tricky perhaps). But I had to make sure the class of self (which I am passing as the delegate) was adopting the UIAlertViewDelegate protocol for the compile errors to go away:

let alertView = UIAlertView(
                  title: "My Title",
                  message: "My Message",
                  delegate: self,
                  cancelButtonTitle: "Cancel",
                  otherButtonTitles: "OK"
                )

By the way, this is the error I was getting (as of Xcode 6.4):

Cannot find an initializer for type 'UIAlertView' that accepts an argument list of type '(title: String, message: String, delegate: MyViewController, cancelButtonTitle: String, otherButtonTitles: String)'

As others mentioned, you should migrate to UIAlertController if you can target iOS 8.x+. To support iOS 7, use the code above (iOS 6 is not supported by Swift).

I would use it-str.begin() In this particular case std::distance and operator- are the same. But if container will change to something without random access, std::distance will increment first argument until it reach second, giving thus linear time and operator- will not compile. Personally I prefer the second behaviour - it's better to be notified when you algorithm from O(n) became O(n^2)...

Java native code necessities:

• h/w access and control.
• use of commercial s/w and system services[h/w related].
• use of legacy s/w that hasn't or cannot be ported to Java.
• Using native code to perform time-critical tasks.

hope these points answers your question :)

It can also be caused by piping out of a pair of curly braces on a line.

This fails:

{ /usr/local/bin/mycommand ; outputstatus=$? } >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

while this is allowed:

{
   /usr/local/bin/mycommand
   outputstatus=$?
} >> /var/log/mycommand.log 2>&1h
do_something
#Get NOW that saved output status for the following $? invocation
sh -c "exit $outputstatus"
do_something_more

If you are not very offended by the GOTO keyword, it can be used to simulate a DO / WHILE in T-SQL. Consider the following rather nonsensical example written in pseudocode:

SET I=1
DO
 PRINT I
 SET I=I+1
WHILE I<=10

Here is the equivalent T-SQL code using goto:

DECLARE @I INT=1;
START:                -- DO
  PRINT @I;
  SET @I+=1;
IF @I<=10 GOTO START; -- WHILE @I<=10

Notice the one to one mapping between the GOTO enabled solution and the original DO / WHILE pseudocode. A similar implementation using a WHILE loop would look like:

DECLARE @I INT=1;
WHILE (1=1)              -- DO
 BEGIN
  PRINT @I;
  SET @I+=1;
  IF NOT (@I<=10) BREAK; -- WHILE @I<=10
 END

Now, you could of course rewrite this particular example as a simple WHILE loop, since this is not such a good candidate for a DO / WHILE construct. The emphasis was on example brevity rather than applicability, since legitimate cases requiring a DO / WHILE are rare.

REPEAT / UNTIL, anyone (does NOT work in T-SQL)?

SET I=1
REPEAT
  PRINT I
  SET I=I+1
UNTIL I>10

... and the GOTO based solution in T-SQL:

DECLARE @I INT=1;
START:                    -- REPEAT
  PRINT @I;
  SET @I+=1;
IF NOT(@I>10) GOTO START; -- UNTIL @I>10

Through creative use of GOTO and logic inversion via the NOT keyword, there is a very close relationship between the original pseudocode and the GOTO based solution. A similar solution using a WHILE loop looks like:

DECLARE @I INT=1;
WHILE (1=1)       -- REPEAT
 BEGIN
  PRINT @I;
  SET @I+=1;
  IF @I>10 BREAK; -- UNTIL @I>10
 END

An argument can be made that for the case of the REPEAT / UNTIL, the WHILE based solution is simpler, because the if condition is not inverted. On the other hand it is also more verbose.

If it wasn't for all of the disdain around the use of GOTO, these might even be idiomatic solutions for those few times when these particular (evil) looping constructs are necessary in T-SQL code for the sake of clarity.

Use these at your own discretion, trying not to suffer the wrath of your fellow developers when they catch you using the much maligned GOTO.

According to BufferedReader source, in this case bReader.close call fReader.close so technically you do not have to call the latter.

Its because you can not access local file without running local web server as per CORS policy so in order to running it you must have some host server.

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

if (!*ptr) { /* empty string  */}

similarly

if (*ptr)  { /* not empty */ }

This worked for me:

Step 1: Stop MySQL daemon if it is currently running

  ps -ef | grep mysql      - checks if mysql/mysqld is one of the running processes.

  pkill mysqld             - kills the daemon, if it is running.

Step 2: Run MySQL safe daemon with skipping grant tables

  mysqld_safe --skip-grant-tables &

  mysql -u root mysql

Step 3: Login to MySQL as root with no password

  mysql -u root mysql

Step 4: Run UPDATE query to reset the root password

  UPDATE user SET password=PASSWORD("value=42") WHERE user="root";
  FLUSH PRIVILEGES;

In MySQL 5.7, the 'password' field was removed, now the field name is 'authentication_string':

  UPDATE user SET authentication_string=PASSWORD("42") WHERE 
  user="root";
  FLUSH PRIVILEGES;

Step 5: Stop MySQL safe daemon

Step 6: Start MySQL daemon

Mine was fixed by just using this command :-

      >git config --global http.proxy XXX.XXX.XXX.XXX:ZZ

where XXX.XXX.XXX.XXX is the proxy server address and ZZ is the port number of the proxy server.

There was no need to specify any username or password in my case.

This issue can also happen if you're trying to install a package that doesn't exist or if you're trying to install a version that doesn't exist.

Summary ArrayList with ArrayDeque are preferable in many more use-cases than LinkedList. If you're not sure — just start with ArrayList.

TLDR, in ArrayList accessing an element takes constant time [O(1)] and adding an element takes O(n) time [worst case]. In LinkedList adding an element takes O(n) time and accessing also takes O(n) time but LinkedList uses more memory than ArrayList.

LinkedList and ArrayList are two different implementations of the List interface. LinkedList implements it with a doubly-linked list. ArrayList implements it with a dynamically re-sizing array.

As with standard linked list and array operations, the various methods will have different algorithmic runtimes.

For LinkedList<E>

• get(int index) is O(n) (with n/4 steps on average), but O(1) when index = 0 or index = list.size() - 1 (in this case, you can also use getFirst() and getLast()). One of the main benefits of LinkedList<E>
• add(int index, E element) is O(n) (with n/4 steps on average), but O(1) when index = 0 or index = list.size() - 1 (in this case, you can also use addFirst() and addLast()/add()). One of the main benefits of LinkedList<E>
• remove(int index) is O(n) (with n/4 steps on average), but O(1) when index = 0 or index = list.size() - 1 (in this case, you can also use removeFirst() and removeLast()). One of the main benefits of LinkedList<E>
• Iterator.remove() is O(1). One of the main benefits of LinkedList<E>
• ListIterator.add(E element) is O(1). One of the main benefits of LinkedList<E>

^{Note: Many of the operations need n/4 steps on average, constant number of steps in the best case (e.g. index = 0), and n/2 steps in worst case (middle of list)}

For ArrayList<E>

• get(int index) is O(1). Main benefit of ArrayList<E>
• add(E element) is O(1) amortized, but O(n) worst-case since the array must be resized and copied
• add(int index, E element) is O(n) (with n/2 steps on average)
• remove(int index) is O(n) (with n/2 steps on average)
• Iterator.remove() is O(n) (with n/2 steps on average)
• ListIterator.add(E element) is O(n) (with n/2 steps on average)

^{Note: Many of the operations need n/2 steps on average, constant number of steps in the best case (end of list), n steps in the worst case (start of list)}

LinkedList<E> allows for constant-time insertions or removals using iterators, but only sequential access of elements. In other words, you can walk the list forwards or backwards, but finding a position in the list takes time proportional to the size of the list. Javadoc says "operations that index into the list will traverse the list from the beginning or the end, whichever is closer", so those methods are O(n) (n/4 steps) on average, though O(1) for index = 0.

ArrayList<E>, on the other hand, allow fast random read access, so you can grab any element in constant time. But adding or removing from anywhere but the end requires shifting all the latter elements over, either to make an opening or fill the gap. Also, if you add more elements than the capacity of the underlying array, a new array (1.5 times the size) is allocated, and the old array is copied to the new one, so adding to an ArrayList is O(n) in the worst case but constant on average.

So depending on the operations you intend to do, you should choose the implementations accordingly. Iterating over either kind of List is practically equally cheap. (Iterating over an ArrayList is technically faster, but unless you're doing something really performance-sensitive, you shouldn't worry about this -- they're both constants.)

The main benefits of using a LinkedList arise when you re-use existing iterators to insert and remove elements. These operations can then be done in O(1) by changing the list locally only. In an array list, the remainder of the array needs to be moved (i.e. copied). On the other side, seeking in a LinkedList means following the links in O(n) (n/2 steps) for worst case, whereas in an ArrayList the desired position can be computed mathematically and accessed in O(1).

Another benefit of using a LinkedList arise when you add or remove from the head of the list, since those operations are O(1), while they are O(n) for ArrayList. Note that ArrayDeque may be a good alternative to LinkedList for adding and removing from the head, but it is not a List.

Also, if you have large lists, keep in mind that memory usage is also different. Each element of a LinkedList has more overhead since pointers to the next and previous elements are also stored. ArrayLists don't have this overhead. However, ArrayLists take up as much memory as is allocated for the capacity, regardless of whether elements have actually been added.

The default initial capacity of an ArrayList is pretty small (10 from Java 1.4 - 1.8). But since the underlying implementation is an array, the array must be resized if you add a lot of elements. To avoid the high cost of resizing when you know you're going to add a lot of elements, construct the ArrayList with a higher initial capacity.

If the data structures perspective is used to understand the two structures, a LinkedList is basically a sequential data structure which contains a head Node. The Node is a wrapper for two components : a value of type T [accepted through generics] and another reference to the Node linked to it. So, we can assert it is a recursive data structure (a Node contains another Node which has another Node and so on...). Addition of elements takes linear time in LinkedList as stated above.

An ArrayList, is a growable array. It is just like a regular array. Under the hood, when an element is added at index i, it creates another array with a size which is 1 greater than previous size (So in general, when n elements are to be added to an ArrayList, a new array of size previous size plus n is created). The elements are then copied from previous array to new one and the elements that are to be added are also placed at the specified indices.

return false in your listener should work in all browsers.

$('orderNowForm').addEvent('submit', function () {
    // your code
    return false;
}

private void button1_Click(object sender, EventArgs e)
{
      Form2 m = new Form2();
      m.Show();
      this.Visible = false;
}

Since we cut down a list in to half every time therefore we just need to know in how many steps we get 1 as we go on dividing a list by two. In the under given calculation x denotes the numbers of time we divide a list until we get one element(In Worst Case).

1 = N/2x

2x = N

Taking log2

log2(2x) = log2(N)

x*log2(2) = log2(N)

x = log2(N)

I solved the problem by changing

$db['default']['pconnect'] = TRUE; TO $db['default']['pconnect'] = FALSE;

When you read in git tag man page:

One important aspect of git is it is distributed, and being distributed largely means there is no inherent "upstream" or "downstream" in the system.

, that simply means there is no absolute upstream repo or downstream repo.
Those notions are always relative between two repos and depends on the way data flows:

If "yourRepo" has declared "otherRepo" as a remote one, then:

• you are pulling from upstream "otherRepo" ("otherRepo" is "upstream from you", and you are "downstream for otherRepo").
• you are pushing to upstream ("otherRepo" is still "upstream", where the information now goes back to).

Note the "from" and "for": you are not just "downstream", you are "downstream from/for", hence the relative aspect.

The DVCS (Distributed Version Control System) twist is: you have no idea what downstream actually is, beside your own repo relative to the remote repos you have declared.

• you know what upstream is (the repos you are pulling from or pushing to)
• you don't know what downstream is made of (the other repos pulling from or pushing to your repo).

Basically:

In term of "flow of data", your repo is at the bottom ("downstream") of a flow coming from upstream repos ("pull from") and going back to (the same or other) upstream repos ("push to").

You can see an illustration in the git-rebase man page with the paragraph "RECOVERING FROM UPSTREAM REBASE":

It means you are pulling from an "upstream" repo where a rebase took place, and you (the "downstream" repo) is stuck with the consequence (lots of duplicate commits, because the branch rebased upstream recreated the commits of the same branch you have locally).

That is bad because for one "upstream" repo, there can be many downstream repos (i.e. repos pulling from the upstream one, with the rebased branch), all of them having potentially to deal with the duplicate commits.

Again, with the "flow of data" analogy, in a DVCS, one bad command "upstream" can have a "ripple effect" downstream.

Note: this is not limited to data.
It also applies to parameters, as git commands (like the "porcelain" ones) often call internally other git commands (the "plumbing" ones). See rev-parse man page:

Many git porcelainish commands take mixture of flags (i.e. parameters that begin with a dash '-') and parameters meant for the underlying git rev-list command they use internally and flags and parameters for the other commands they use downstream of git rev-list. This command is used to distinguish between them.

You can also use a second image to give the effect of a button being pressed. Just add the "pressed" button image in the HTML before the input image:

<img src="http://integritycontractingofva.com/images/go2.jpg" id="pressed"/>
<input id="unpressed" type="submit" value=" " style="background:url(http://integritycontractingofva.com/images/go1.jpg) no-repeat;border:none;"/>

And use CSS to change the opacity of the "unpressed" image on hover:

#pressed, #unpressed{position:absolute; left:0px;}
#unpressed{opacity: 1; cursor: pointer;}
#unpressed:hover{opacity: 0;}

I use it for the blue "GO" button on this page

Just download minimum prefered SDK from SDK Manager, then build. Works for me.

You can use a padding for the button and you can play with drawablePadding

 <Button
    style="@style/botonesMenu"
    android:padding="15dp"
    android:drawablePadding="-15dp"
    android:text="@string/actualizarBD"
    android:textAlignment="gravity"
    android:gravity="center"
    android:layout_row="1"
    android:layout_column="0"
    android:drawableTop="@drawable/actualizar"
    android:id="@+id/btnActualizar"
    android:onClick="actualizarBD" />

you can use a specific padding depends where put your drawable, with android:paddingLeft="10dp" or android:paddingBottom="10dp" or android:paddingRight="10dp" or android:paddingTop="10dp"

Double quotes around the filename in the header is the standard per MDN web docs. Omitting the quotes creates multiple opportunities for problems arising from characters in the filename.

Use below code to populate selected option from your model.

<select id="roomForListing" ng-model="selectedRoom.roomName" >

<option ng-repeat="room in roomList" title="{{room.roomName}}" ng-selected="{{room.roomName == selectedRoom.roomName}}" value="{{room.roomName}}">{{room.roomName}}</option>

</select>

This is an Oracle-specific notation for an outer join. It means that it will include all rows from t1, and use NULLS in the t0 columns if there is no corresponding row in t0.

In standard SQL one would write:

SELECT t0.foo, t1.bar
  FROM FIRST_TABLE t0
 RIGHT OUTER JOIN SECOND_TABLE t1;

Oracle recommends not to use those joins anymore if your version supports ANSI joins (LEFT/RIGHT JOIN) :

Oracle recommends that you use the FROM clause OUTER JOIN syntax rather than the Oracle join operator. Outer join queries that use the Oracle join operator (+) are subject to the following rules and restrictions […]

You should be able to control all your headers by skipping loadUrl and writing your own loadPage using Java's HttpURLConnection. Then use the webview's loadData to display the response.

There is no access to the headers which Google provides. They are in a JNI call, deep in the WebView source.

Just to improve YCR's answer:

1) I added black lines on x and y axis. Otherwise they are made transparent too.

2) I added a transparent theme to the legend key. Otherwise, you will get a fill there, which won't be very esthetic.

Finally, note that all those work only with pdf and png formats. jpeg fails to produce transparent graphs.

MyTheme_transparent <- theme(
    panel.background = element_rect(fill = "transparent"), # bg of the panel
    plot.background = element_rect(fill = "transparent", color = NA), # bg of the plot
    panel.grid.major = element_blank(), # get rid of major grid
    panel.grid.minor = element_blank(), # get rid of minor grid
    legend.background = element_rect(fill = "transparent"), # get rid of legend bg
    legend.box.background = element_rect(fill = "transparent"), # get rid of legend panel bg
    legend.key = element_rect(fill = "transparent", colour = NA), # get rid of key legend fill, and of the surrounding
    axis.line = element_line(colour = "black") # adding a black line for x and y axis
)

BLOB :

BLOB (Binary Large Object) is a large object data type in the database system. BLOB could store a large chunk of data, document types and even media files like audio or video files. BLOB fields allocate space only whenever the content in the field is utilized. BLOB allocates spaces in Giga Bytes.

USAGE OF BLOB :

You can write a binary large object (BLOB) to a database as either binary or character data, depending on the type of field at your data source. To write a BLOB value to your database, issue the appropriate INSERT or UPDATE statement and pass the BLOB value as an input parameter. If your BLOB is stored as text, such as a SQL Server text field, you can pass the BLOB as a string parameter. If the BLOB is stored in binary format, such as a SQL Server image field, you can pass an array of type byte as a binary parameter.

A useful link : Storing documents as BLOB in Database - Any disadvantages ?

There are lot of wonderful answers on this thread already. However I wanted to share my experience when I tried to solve "remove nth element from array" in ES5 context.

JavaScript arrays have different methods to add/remove elements from start or end. These are:

arr.push(ele) - To add element(s) at the end of the array 
arr.unshift(ele) - To add element(s) at the beginning of the array
arr.pop() - To remove last element from the array 
arr.shift() - To remove first element from the array 

Essentially none of the above methods can be used directly to remove nth element from the array.

A fact worth noting is that this is in contrast with java iterator's using which it is possible to remove nth element for a collection while iterating.

This basically leaves us with only one array method Array.splice to perform removal of nth element (there are other things you could do with these methods as well, but in the context of this question I am focusing on removal of elements):

Array.splice(index,1) - removes the element at the index 

Here is the code copied from original answer (with comments):

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter else it would run into IndexOutBounds exception_x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    //splice modifies the original array_x000D_
    arr.splice(i, 1); //never runs into IndexOutBounds exception _x000D_
    console.log("Element removed. arr: ");_x000D_
_x000D_
  } else {_x000D_
    console.log("Element not removed. arr: ");_x000D_
  }_x000D_
  console.log(arr);_x000D_
}

Another noteworthy method is Array.slice. However the return type of this method is the removed elements. Also this doesn't modify original array. Modified code snippet as follows:

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter _x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    console.log("Element removed. arr: ");_x000D_
    console.log(arr.slice(i, i + 1));_x000D_
    console.log("Original array: ");_x000D_
    console.log(arr);_x000D_
  }_x000D_
}

Having said that, we can still use Array.slice to remove nth element as shown below. However it is lot more code (hence inefficient)

var arr = ["one", "two", "three", "four"];_x000D_
var i = arr.length; //initialize counter to array length _x000D_
_x000D_
while (i--) //decrement counter _x000D_
{_x000D_
  if (arr[i] === "four" || arr[i] === "two") {_x000D_
    console.log("Array after removal of ith element: ");_x000D_
    arr = arr.slice(0, i).concat(arr.slice(i + 1));_x000D_
    console.log(arr);_x000D_
  }_x000D_
_x000D_
}

The Array.slice method is extremely important to achieve immutability in functional programming à la redux

CSS selector:

Use a CSS selector of img[src='images/toolbar/b_edit.gif']

This says select element(s) with img tag with attribute src having value of 'images/toolbar/b_edit.gif'

You can apply the selector with the .querySelector method of document.

IE.document.querySelector("img[src='images/toolbar/b_edit.gif']").Click

I know this is old, but just thought I would add my solution just in case someone finds it useful.

I wanted to compare the local naive datetime with an aware datetime from a timeserver. I basically created a new naive datetime object using the aware datetime object. It's a bit of a hack and doesn't look very pretty but gets the job done.

import ntplib
import datetime
from datetime import timezone

def utc_to_local(utc_dt):
    return utc_dt.replace(tzinfo=timezone.utc).astimezone(tz=None)    

try:
    ntpt = ntplib.NTPClient()
    response = ntpt.request('pool.ntp.org')
    date = utc_to_local(datetime.datetime.utcfromtimestamp(response.tx_time))
    sysdate = datetime.datetime.now()

...here comes the fudge...

    temp_date = datetime.datetime(int(str(date)[:4]),int(str(date)[5:7]),int(str(date)[8:10]),int(str(date)[11:13]),int(str(date)[14:16]),int(str(date)[17:19]))
    dt_delta = temp_date-sysdate
except Exception:
    print('Something went wrong :-(')

"1232 23 2 23 232 232".delete(' ')
=> "123223223232232"

Delete works faster =)

Use mktime():

<?php
 $monthNum = 5;
 $monthName = date("F", mktime(0, 0, 0, $monthNum, 10));
 echo $monthName; // Output: May
?>

Turned out there was some extra code in the AppModel that was messing things up:

in beforeFind and afterFind:

App::Import("Session");
$session = new CakeSession();
$sim_id = $session->read("Simulation.id");

I don't know why, but that was what the problem was. Removing those lines fixed the issue I was having.

You need to add path to svn.exe file to system environment, variable PATH, after that you can run command mvn from any folder. You can do it from command line(cmd.exe) like this, for example:

set PATH=%PATH%;C:\maven\bin

Or you can got to the folder where mvn.exe is, and run your command there.

And you need not mvn -version, but mvn --version parameter.

I wasn't able to do this:

UPDATE users SET created = NULL WHERE created = '0000-00-00 00:00:00'

(on MySQL 5.7.13).

I kept getting the Incorrect datetime value: '0000-00-00 00:00:00' error.

Strangely, this worked: SELECT * FROM users WHERE created = '0000-00-00 00:00:00'. I have no idea why the former fails and the latter works... maybe a MySQL bug?

At any case, this UPDATE query worked:

UPDATE users SET created = NULL WHERE CAST(created AS CHAR(20)) = '0000-00-00 00:00:00'

From the Python PEP 8 -- Style Guide for Python Code:

Descriptive: Naming Styles

The following special forms using leading or trailing underscores are recognized (these can generally be combined with any case convention):

• _single_leading_underscore: weak "internal use" indicator. E.g. from M import * does not import objects whose name starts with an underscore.

• single_trailing_underscore_: used by convention to avoid conflicts with Python keyword, e.g.

  Tkinter.Toplevel(master, class_='ClassName')

• __double_leading_underscore: when naming a class attribute, invokes name mangling (inside class FooBar, __boo becomes _FooBar__boo; see below).

• __double_leading_and_trailing_underscore__: "magic" objects or attributes that live in user-controlled namespaces. E.g. __init__, __import__ or __file__. Never invent such names; only use them as documented.

Note that names with double leading and trailing underscores are essentially reserved for Python itself: "Never invent such names; only use them as documented".

You can use the dotenv package no matter what setup you use. It allows you to create a .env in your project root and specify your keys like so

REACT_APP_SERVER_PORT=8000

In your applications entry file your just call dotenv(); before accessing the keys like so

Try using white-space: nowrap; in the container style (instead of overflow: hidden;)

The error happens because of you are trying to map a numeric vector to data in geom_errorbar: GVW[1:64,3]. ggplot only works with data.frame.

In general, you shouldn't subset inside ggplot calls. You are doing so because your standard errors are stored in four separate objects. Add them to your original data.frame and you will be able to plot everything in one call.

Here with a dplyr solution to summarise the data and compute the standard error beforehand.

library(dplyr)
d <- GVW %>% group_by(Genotype,variable) %>%
    summarise(mean = mean(value),se = sd(value) / sqrt(n()))

ggplot(d, aes(x = variable, y = mean, fill = Genotype)) + 
  geom_bar(position = position_dodge(), stat = "identity", 
      colour="black", size=.3) +
  geom_errorbar(aes(ymin = mean - se, ymax = mean + se), 
      size=.3, width=.2, position=position_dodge(.9)) +
  xlab("Time") +
  ylab("Weight [g]") +
  scale_fill_hue(name = "Genotype", breaks = c("KO", "WT"), 
      labels = c("Knock-out", "Wild type")) +
  ggtitle("Effect of genotype on weight-gain") +
  scale_y_continuous(breaks = 0:20*4) +

I haven't used Cassandra, but I have used MongoDB and think it's awesome.

If you're after simple setup, this is it: You simply untar MongoDB and run the mongod daemon and that's it ... it's running.

Obviously that's only a starter, but to get you started it's easy.

Years ago, I implemented the following hashtable, which has had some features that have been missing to the Map class. However, that's no longer the case. Now it's possible to iterate over the entries of a Map, get an array of its keys or values or both (these operations are implemented copying to a newly allocated array, though — that's a waste of memory and its time complexity will always be as bad as O(n)), remove specific items given their key, and clear the whole map. Therefore, my hashtable implementation is only useful for compatibility purposes, though in this case it would be more appropriate to write a proper polyfill. I'd suggest to anyone who would use my hashtable implementation to change it so to make it become a polyfill for the Map class.

function Hashtable() {
    this._map = new Map();
    this._indexes = new Map();
    this._keys = [];
    this._values = [];
    this.put = function(key, value) {
        var newKey = !this.containsKey(key);
        this._map.set(key, value);
        if (newKey) {
            this._indexes.set(key, this.length);
            this._keys.push(key);
            this._values.push(value);
        }
    };
    this.remove = function(key) {
        if (!this.containsKey(key))
            return;
        this._map.delete(key);
        var index = this._indexes.get(key);
        this._indexes.delete(key);
        this._keys.splice(index, 1);
        this._values.splice(index, 1);
    };
    this.indexOfKey = function(key) {
        return this._indexes.get(key);
    };
    this.indexOfValue = function(value) {
        return this._values.indexOf(value) != -1;
    };
    this.get = function(key) {
        return this._map.get(key);
    };
    this.entryAt = function(index) {
        var item = {};
        Object.defineProperty(item, "key", {
            value: this.keys[index],
            writable: false
        });
        Object.defineProperty(item, "value", {
            value: this.values[index],
            writable: false
        });
        return item;
    };
    this.clear = function() {
        var length = this.length;
        for (var i = 0; i < length; i++) {
            var key = this.keys[i];
            this._map.delete(key);

        }
        this._keys.splice(0, length);
    };
    this.containsKey = function(key) {
        return this._map.has(key);
    };
    this.containsValue = function(value) {
        return this._values.indexOf(value) != -1;
    };
    this.forEach = function(iterator) {
        for (var i = 0; i < this.length; i++)
            iterator(this.keys[i], this.values[i], i);
    };
    Object.defineProperty(this, "length", {
        get: function() {

import pandas as pd

This approach will not consume any resources for keeping process alive.

while :; do sleep 1; done & kill -STOP $! && wait $!

Breakdown

• while :; do sleep 1; done & Creates a dummy process in background
• kill -STOP $! Stops the background process
• wait $! Wait for the background process, this will be blocking forever, cause background process was stopped before

I'd use

files=(*)

And then if you need data about the file, such as size, use the stat command on each file.

Like others said, you can just loop over the array and print out the elements one by one. To make the output show up as numbers instead of "letters and symbols" you were seeing, you need to convert each element to a string. So your code becomes something like this:

public static void write (String filename, int[]x) throws IOException{
  BufferedWriter outputWriter = null;
  outputWriter = new BufferedWriter(new FileWriter(filename));
  for (int i = 0; i < x.length; i++) {
    // Maybe:
    outputWriter.write(x[i]+"");
    // Or:
    outputWriter.write(Integer.toString(x[i]);
    outputWriter.newLine();
  }
  outputWriter.flush();  
  outputWriter.close();  
}

If you just want to print out the array like [1, 2, 3, ....], you can replace the loop with this one liner:

outputWriter.write(Arrays.toString(x));

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

A functional notation type conversion (5.2.3) can be used to create new objects of its type. [Note: The syntax looks like an explicit call of the constructor. ] ... An object created in this way is unnamed. [Note: 12.2 describes the lifetime of temporary objects. ] [Note: explicit constructor calls do not yield lvalues, see 3.10. ]

Where to read about RVO:

I got this error after change a loop in my program, let`s see:

for ...
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:

for ...
  x_batch = []
  y_batch = []
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

Then, check if you are using np.asarray() or something like that.

Here is another way to do it.It is working fine for me .

N=int(input())
num1 = list(map(int, input().split()))
num2 = list(map(int, input().split()))
sum=[]

for i in range(0,N):
  sum.append(num1[i]+num2[i])

for element in sum:
  print(element, end=" ")

print("")

As Alexander M. mentioned, you'll still have to use GParted, Partition Magic or a similar partition editor to grow your partition to the newly allocated physical drive. To do this just download the GParted iso, mount it as a bootable drive in the VirtualBox and boot from it.

http://momentjs.com/ or https://date-fns.org/

From Moment docs:

var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days')   // =1

or to include the start:

a.diff(b, 'days')+1   // =2

Beats messing with timestamps and time zones manually.

Depending on your specific use case, you can either

1. Use a/b.startOf('day') and/or a/b.endOf('day') to force the diff to be inclusive or exclusive at the "ends" (as suggested by @kotpal in the comments).
2. Set third argument true to get a floating point diff which you can then Math.floor, Math.ceil or Math.round as needed.
3. Option 2 can also be accomplished by getting 'seconds' instead of 'days' and then dividing by 24*60*60.

I've found a more reliable method (at least on Excel 2016 for Mac) is:

Assuming your long list is in column A, and the list of things to be removed from this is in column B, then paste this into all the rows of column C:

= IF(COUNTIF($B$2:$B$99999,A2)>0,"Delete","Keep")

Then just sort the list by column C to find what you have to delete.

I use jQuery BeautyTips to achieve the little bubble effect you are talking about. I don't use the Validation plugin so I can't really help much there, but it is very easy to style and show the BeautyTips. You should look into it. It's not as simple as just CSS rules, I'm afraid, as you need to use the canvas element and include an extra javascript file for IE to play nice with it.

Does the -verbose flag to your java command yield any useful info? If not, maybe java -X reveals something specific to your version that might help?

When you have a copy of an object the [checked] attribute might not work, in that case, you can use (change) in this way:

        <input type="checkbox" [checked]="item.selected" (change)="item.selected = !item.selected">

No, there is not; see §3.2.4 "Compound Commands" in the Bash Reference Manual for information about the control structures that do exist. In particular, note the mention of break and continue, which aren't as flexible as goto, but are more flexible in Bash than in some languages, and may help you achieve what you want. (Whatever it is that you want . . .)

For me, I needed to keep the TextboxFor() because using EditorFor() changes the input type to date. Which, in Chrome, adds a built in date picker, which screwed up the jQuery datepicker that I was already using. So, to continue using TextboxFor() AND only output the date, you can do this:

<tr>
    <td class="Label">@Html.LabelFor(model => model.DeliveryDate)</td>
    @{
        string deliveryDate = Model.DeliveryDate.ToShortDateString();
    }
    <td>@Html.TextBoxFor(model => model.DeliveryDate, new { @Value = deliveryDate }) *</td>
    <td style="color: red;">@Html.ValidationMessageFor(model => model.DeliveryDate)</td>
</tr>

preg_match_all('/\".*?\"/i', $string, $matches);

Pretty much everything was faster at least by at 200% when contrasted with mongodb, than one exception right now is a update which requires completely rewriting the entire json column something mongodb handles better.

The gin indexing on on jsonb sounds amazing.

Also postgres will persist types of jsonb internally and basically match this with types such as numeric, text, boolean etc.

Joins will also be possible using jsonb

Add PLv8 for stored procedures and this will basically be a dream come true for node.js developers.

Being it's stored as binary jsonb will also strip all whitespace, change the ordering of properties and remove duplicate properties using the last occurance of the property.

Besides the index when querying against a jsonb column contrasted to a json column postgres doesn't have to actually run the functionality to convert the text to json on every row which will likely save a vast amount of time alone.

If you have a JS array of JSON objects:

var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];

and you want an array of objects:

// JavaScript array of JavaScript objects
var objs = s.map(JSON.parse);

// ...or for older browsers
var objs=[];
for (var i=s.length;i--;) objs[i]=JSON.parse(s[i]);

// ...or for maximum speed:
var objs = JSON.parse('['+s.join(',')+']');

See the speed tests for browser comparisons.

If you have a single JSON string representing an array of objects:

var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

and you want an array of objects:

// JavaScript array of JavaScript objects
var objs = JSON.parse(s);

If you have an array of objects:

// A JavaScript array of JavaScript objects
var s = [{"Select":"11", "PhotoCount":"12"},{"Select":"21", "PhotoCount":"22"}];

…and you want JSON representation for it, then:

// JSON string representing an array of objects
var json = JSON.stringify(s);

…or if you want a JavaScript array of JSON strings, then:

// JavaScript array of strings (that are each a JSON object)
var jsons = s.map(JSON.stringify);

// ...or for older browsers
var jsons=[];
for (var i=s.length;i--;) jsons[i]=JSON.stringify(s[i]);

Use the utf8 module from npm to encode/decode the string.

Installation:

npm install utf8

In a browser:

<script src="utf8.js"></script>

In Node.js:

const utf8 = require('utf8');

API:

Encode:

utf8.encode(string)

Encodes any given JavaScript string (string) as UTF-8, and returns the UTF-8-encoded version of the string. It throws an error if the input string contains a non-scalar value, i.e. a lone surrogate. (If you need to be able to encode non-scalar values as well, use WTF-8 instead.)

// U+00A9 COPYRIGHT SIGN; see http://codepoints.net/U+00A9
utf8.encode('\xA9');
// ? '\xC2\xA9'
// U+10001 LINEAR B SYLLABLE B038 E; see http://codepoints.net/U+10001
utf8.encode('\uD800\uDC01');
// ? '\xF0\x90\x80\x81'

Decode:

utf8.decode(byteString)

Decodes any given UTF-8-encoded string (byteString) as UTF-8, and returns the UTF-8-decoded version of the string. It throws an error when malformed UTF-8 is detected. (If you need to be able to decode encoded non-scalar values as well, use WTF-8 instead.)

utf8.decode('\xC2\xA9');
// ? '\xA9'

utf8.decode('\xF0\x90\x80\x81');
// ? '\uD800\uDC01'
// ? U+10001 LINEAR B SYLLABLE B038 E

My problem with this one was that I was creating a hibernate session, but had the JNDI settings for my database instance wrong because of a classpath problem. Just FYI...

SELECT last_number
  FROM all_sequences
 WHERE sequence_owner = '<sequence owner>'
   AND sequence_name = '<sequence_name>';

You can get a variety of sequence metadata from user_sequences, all_sequences and dba_sequences.

These views work across sessions.

EDIT:

If the sequence is in your default schema then:

SELECT last_number
  FROM user_sequences
 WHERE sequence_name = '<sequence_name>';

If you want all the metadata then:

SELECT *
  FROM user_sequences
 WHERE sequence_name = '<sequence_name>';

Hope it helps...

EDIT2:

A long winded way of doing it more reliably if your cache size is not 1 would be:

SELECT increment_by I
  FROM user_sequences
 WHERE sequence_name = 'SEQ';

      I
-------
      1

SELECT seq.nextval S
  FROM dual;

      S
-------
   1234

-- Set the sequence to decrement by 
-- the same as its original increment
ALTER SEQUENCE seq 
INCREMENT BY -1;

Sequence altered.

SELECT seq.nextval S
  FROM dual;

      S
-------
   1233

-- Reset the sequence to its original increment
ALTER SEQUENCE seq 
INCREMENT BY 1;

Sequence altered.

Just beware that if others are using the sequence during this time - they (or you) may get

ORA-08004: sequence SEQ.NEXTVAL goes below the sequences MINVALUE and cannot be instantiated

Also, you might want to set the cache to NOCACHE prior to the resetting and then back to its original value afterwards to make sure you've not cached a lot of values.

You can unite this

x = 0
y = 1
z = 3

in one variable.

In [1]: xyz = (0,1,3,) 
In [2]: mylist = []

Change our conditions as:

In [3]: if 0 in xyz: 
    ...:     mylist.append("c") 
    ...: if 1 in xyz: 
    ...:     mylist.append("d") 
    ...: if 2 in xyz: 
    ...:     mylist.append("e") 
    ...: if 3 in xyz:  
    ...:     mylist.append("f") 

Output:

In [21]: mylist                                                                                
Out[21]: ['c', 'd', 'f']

function _formatDatetime(date: Date, format: string) {
   const _padStart = (value: number): string => value.toString().padStart(2, '0');
return format
    .replace(/yyyy/g, _padStart(date.getFullYear()))
    .replace(/dd/g, _padStart(date.getDate()))
    .replace(/mm/g, _padStart(date.getMonth() + 1))
    .replace(/hh/g, _padStart(date.getHours()))
    .replace(/ii/g, _padStart(date.getMinutes()))
    .replace(/ss/g, _padStart(date.getSeconds()));
}
function isValidDate(d: Date): boolean {
    return !isNaN(d.getTime());
}
export function formatDate(date: any): string {
    var datetime = new Date(date);
    return isValidDate(datetime) ? _formatDatetime(datetime, 'yyyy-mm-dd hh:ii:ss') : '';
}

Change the property WindowState to System.Windows.Forms.FormWindowState.Maximized, in some cases if the older answers doesn't works.

So the window will be maximized, and the other parts are in the other answers.

I had similar problem with Yarn, none of above worked for me, so I simply removed ./node_modules and run yarn install and problem gone.

do not turn off firewall, Go Control Panel\System and Security\Windows Firewall then Advanced settings then Inbound Rules->From right pan choose New Rule-> Port-> TCP and type in port number 80 then give a name in next window, that's it.

I ran into this problem as well, and figured out that the problem is in the browser. When you refresh the browser is re-populating the form with the same values as before, ignoring the checked field. If you view source, you'll see the checked value is correct. Or put your cursor in your browser's URL field and hit enter. That will re-load the form from scratch.

Call this function onclick of button

/*pass whatever you want instead of id */
function doConfirm(id) {
    var ok = confirm("Are you sure to Delete?");
    if (ok) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }

        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                window.location = "create_dealer.php";
            }
        }

        xmlhttp.open("GET", "delete_dealer.php?id=" + id);
        // file name where delete code is written
        xmlhttp.send();
    }
}

raw_list = [1,2,3,3,4,5,6,6,7,2,3,4,2,3,4,1,3,4,]

clean_list = list(set(raw_list))
duplicated_items = []

for item in raw_list:
    try:
        clean_list.remove(item)
    except ValueError:
        duplicated_items.append(item)


print(duplicated_items)
# [3, 6, 2, 3, 4, 2, 3, 4, 1, 3, 4]

You basically remove duplicates by converting to set (clean_list), then iterate the raw_list, while removing each item in the clean list for occurrence in raw_list. If item is not found, the raised ValueError Exception is caught and the item is added to duplicated_items list.

If the index of duplicated items is needed, just enumerate the list and play around with the index. (for index, item in enumerate(raw_list):) which is faster and optimised for large lists (like thousands+ of elements)

A generic solution especially for Windows Edge browser (as the -ms-user-select: none; CSS rule doesn't work):

window.ondragstart = function() {return false}

Note: This can save you having to add draggable="false" to every img tag when you still need the click event (i.e. you can't use pointer-events: none), but don't want the drag icon image to appear.

1. Create a string by joining the array.
2. Create string by repetition of the first character of the given array
3. match both strings

 function checkArray(array){_x000D_
  return array.join("") == array[0].repeat(array.length); _x000D_
 }_x000D_
_x000D_
 console.log('array: [a,a,a,a]: ' + checkArray(['a', 'a', 'a', 'a']));_x000D_
 console.log('array: [a,a,b,a]: ' + checkArray(['a', 'a', 'b', 'a']));

And you are DONE !

Try this if you don't want to use the UDF function.

SELECT COLUMN1, TRY_CONVERT(xml, COLUMN2).value('.', 'nvarchar(max)') as COL2, COLUMN3
FROM   DBO.TABLENAME        

for i in ...:
    for j in ...:
        for k in ...:
            if something:
                # continue loop i

In a general case, when you have multiple levels of looping and break does not work for you (because you want to continue one of the upper loops, not the one right above the current one), you can do one of the following

Refactor the loops you want to escape from into a function

def inner():
    for j in ...:
        for k in ...:
            if something:
                return


for i in ...:
    inner()

The disadvantage is that you may need to pass to that new function some variables, which were previously in scope. You can either just pass them as parameters, make them instance variables on an object (create a new object just for this function, if it makes sense), or global variables, singletons, whatever (ehm, ehm).

Or you can define inner as a nested function and let it just capture what it needs (may be slower?)

for i in ...:
    def inner():
        for j in ...:
            for k in ...:
                if something:
                    return
    inner()

Use exceptions

Philosophically, this is what exceptions are for, breaking the program flow through the structured programming building blocks (if, for, while) when necessary.

The advantage is that you don't have to break the single piece of code into multiple parts. This is good if it is some kind of computation that you are designing while writing it in Python. Introducing abstractions at this early point may slow you down.

Bad thing with this approach is that interpreter/compiler authors usually assume that exceptions are exceptional and optimize for them accordingly.

class ContinueI(Exception):
    pass


continue_i = ContinueI()

for i in ...:
    try:
        for j in ...:
            for k in ...:
                if something:
                    raise continue_i
    except ContinueI:
        continue

Create a special exception class for this, so that you don't risk accidentally silencing some other exception.

Something else entirely

I am sure there are still other solutions.

I've come across the same issue after adding the following dependency:

implementation 'com.evernote:android-state:1.4.1'
annotationProcessor 'com.evernote:android-state-processor:1.4.1'

And the reason was that latest version of evernote uses dependencies to AndroidX, while I had support library version 27.1.1 in my project. So there was an option of upgrading support libraries to 28.0.0, as the other answers suggest, but that was a bit tricky for a large project with lots of custom views. So, I resolved the issue by downgrading evernote version to 1.3.1.

PHP will work only on the .php file extension.

If you are on Apache you can also set, in your httpd.conf file, the extensions for PHP. You'll have to find the line:

AddType application/x-httpd-php .php .html
                                     ^^^^^

and add how many extensions, that should be read with the PHP interpreter, as you want.
