It is very hard set caret in proper position when you have advance element like (p) (span) etc. The goal is to get (object text):

<div id="editable" contenteditable="true">dddddddddddddddddddddddddddd<p>dd</p>psss<p>dd</p>
    <p>dd</p>
    <p>text text text</p>
</div>
<p id='we'></p>
<button onclick="set_mouse()">focus</button>
<script>

    function set_mouse() {
        var as = document.getElementById("editable");
        el = as.childNodes[1].childNodes[0];//goal is to get ('we') id to write (object Text) because it work only in object text
        var range = document.createRange();
        var sel = window.getSelection();
        range.setStart(el, 1);
        range.collapse(true);
        sel.removeAllRanges();
        sel.addRange(range);

        document.getElementById("we").innerHTML = el;// see out put of we id
    }
</script>

Since when the edit is complete the focus from the element is always lost you could simply use the onBlur hook.

<div onBlur={(e)=>{console.log(e.currentTarget.textContent)}} contentEditable suppressContentEditableWarning={true}>
     <p>Lorem ipsum dolor.</p>
</div>

A few wrinkles that I don't see being addressed in other answers:

1. the element can contain multiple levels of child nodes (e.g. child nodes that have child nodes that have child nodes...)
2. a selection can consist of different start and end positions (e.g. multiple chars are selected)
3. the node containing a Caret start/end may not be either the element or its direct children

Here's a way to get start and end positions as offsets to the element's textContent value:

// node_walk: walk the element tree, stop when func(node) returns false
function node_walk(node, func) {
  var result = func(node);
  for(node = node.firstChild; result !== false && node; node = node.nextSibling)
    result = node_walk(node, func);
  return result;
};

// getCaretPosition: return [start, end] as offsets to elem.textContent that
//   correspond to the selected portion of text
//   (if start == end, caret is at given position and no text is selected)
function getCaretPosition(elem) {
  var sel = window.getSelection();
  var cum_length = [0, 0];

  if(sel.anchorNode == elem)
    cum_length = [sel.anchorOffset, sel.extentOffset];
  else {
    var nodes_to_find = [sel.anchorNode, sel.extentNode];
    if(!elem.contains(sel.anchorNode) || !elem.contains(sel.extentNode))
      return undefined;
    else {
      var found = [0,0];
      var i;
      node_walk(elem, function(node) {
        for(i = 0; i < 2; i++) {
          if(node == nodes_to_find[i]) {
            found[i] = true;
            if(found[i == 0 ? 1 : 0])
              return false; // all done
          }
        }

        if(node.textContent && !node.firstChild) {
          for(i = 0; i < 2; i++) {
            if(!found[i])
              cum_length[i] += node.textContent.length;
          }
        }
      });
      cum_length[0] += sel.anchorOffset;
      cum_length[1] += sel.extentOffset;
    }
  }
  if(cum_length[0] <= cum_length[1])
    return cum_length;
  return [cum_length[1], cum_length[0]];
}

Update

I've written a cross-browser range and selection library called Rangy that incorporates an improved version of the code I posted below. You can use the selection save and restore module for this particular question, although I'd be tempted to use something like @Nico Burns's answer if you're not doing anything else with selections in your project and don't need the bulk of a library.

Previous answer

You can use IERange (http://code.google.com/p/ierange/) to convert IE's TextRange into something like a DOM Range and use it in conjunction with something like eyelidlessness's starting point. Personally I would only use the algorithms from IERange that do the Range <-> TextRange conversions rather than use the whole thing. And IE's selection object doesn't have the focusNode and anchorNode properties but you should be able to just use the Range/TextRange obtained from the selection instead.

I will write this up fully at some point soon.

Using DOMCharacterDataModified under MutationEvents will lead to the same. The timeout is setup to prevent sending incorrect values (e.g. in Chrome I had some issues with space key)

var timeoutID;
$('[contenteditable]').bind('DOMCharacterDataModified', function() {
    clearTimeout(timeoutID);
    $that = $(this);
    timeoutID = setTimeout(function() {
        $that.trigger('change')
    }, 50)
});
$('[contentEditable]').bind('change', function() {
    console.log($(this).text());
})

JSFIDDLE example

Assuming id is the primary key of table :

SELECT * FROM table WHERE id BETWEEN 10 AND 50

For first 20 results

SELECT * FROM table order by id limit 20;

PDO:FETCH_ASSOC puts the results in an array where values are mapped to their field names.

You can access the name field like this: $user['name'].

I recommend using PDO::FETCH_OBJ. It fetches fields in an object and you can access like this: $user->name

Not that I know of, unless you select from INFORMATION_SCHEMA, as others have mentioned.

However, the SHOW command is pretty flexible, E.g.:

SHOW tables like '%s%'

A generic,simpler and a bit primitive approach to find tag, attribute and value

    Pattern pattern = Pattern.compile("<(\\w+)( +.+)*>((.*))</\\1>");
    System.out.println(pattern.matcher("<asd> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd TEST</asd>").find());
    System.out.println(pattern.matcher("<asd attr='3'> TEST</asd>").find());
    System.out.println(pattern.matcher("<asd> <x>TEST<x>asd>").find());
    System.out.println("-------");
    Matcher matcher = pattern.matcher("<as x> TEST</as>");
    if (matcher.find()) {
        for (int i = 0; i <= matcher.groupCount(); i++) {
            System.out.println(i + ":" + matcher.group(i));
        }
    }

classname.getResourceAsStream() loads a file via the classloader of classname. If the class came from a jar file, that is where the resource will be loaded from.

FileInputStream is used to read a file from the filesystem.

then:

from PIL import Image

At the moment I write this, TCPDF only supports padding for tables.

Link to their forum page with that information

In regards tuncalik's answer, which is great, especially if you want to have a little play with the code :) but it is putting my dates into Excel in American format i.e. 2nd March 2014 in the UK is 02/03/2014 but in the USA its 03/02/2014 with month 1st, then day of week after. I need to have it in UK format, any ideas please?

I have checked it is stored in UK format in my DataTable and also my Excel is set to UK but for some reason when it makes the Excel document it thinks its USA (is this because Microsoft are a USA company :)

I'll try experimenting with culture codes but not sure where to put that yet. Tried but this had no effect.

p.s.

I did have to change one line to get it to work by adding a 'cast' as below

// single worksheet
Excel._Worksheet workSheet = (Excel._Worksheet)excelApp.ActiveSheet;

Update: I have achieved UK formatting of the dates by converting to LongDateTime format, its only a work around though.

DateTime startDate = Convert.ToDateTime(myList[0].ToString());
string strStartDate = startDate.ToLongDateString();
DateTime endDate = Convert.ToDateTime(myList[myListTotalRows].ToString());
string strEndDate = endDate.ToLongDateString();    

cheers.

Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.

So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.

There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.

Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example

class MyInput
{
    String str1;
    String str2;

    public MyInput() { }
      //  getters, setters
 }

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}

Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.

The last option is to construct a POST body that looks like:

str1=value1&str2=value2

then add some additional annotations to your server method:

public void create(@QueryParam("str1") String str1, 
                  @QueryParam("str2") String str2)

@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).

If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

Take a look at ?legend and try this:

legend('topright', names(a)[-1] , 
   lty=1, col=c('red', 'blue', 'green',' brown'), bty='n', cex=.75)

It's as simple as that:

function isMacintosh() {
  return navigator.platform.indexOf('Mac') > -1
}

function isWindows() {
  return navigator.platform.indexOf('Win') > -1
}

You can do funny things then like:

var isMac = isMacintosh();
var isPC = !isMacintosh();

Another one is OxyPlot, which is an open-source cross-platform (WPF, Silverlight, WinForms, Mono) .Net plotting library.

Remove that statement from your manifest altogether, Eclipse will handle that for you on the fly.

Date d = new Date(i * 1000 + TimeZone.getDefault().getRawOffset());

I had the same error turns out the only thing i did wrong was to name my 'templates' folder,'template' without 's'. After changing that it worked fine,dont know why its a thing but it is.

Simply supplying the HTML of elements you want to add to a jQuery constructor $() will return a jQuery object from newly built HTML, suitable for being appended into the DOM using jQuery's append() method.

For example:

var t = $("<table cellspacing='0' class='text'></table>");
$.append(t);

You could then populate this table programmatically, if you wished.

This gives you the ability to specify any arbitrary HTML you like, including class names or other attributes, which you might find more concise than using createElement and then setting attributes like cellSpacing and className via JS.

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

For your case Elasticdump is the perfect answer.
First, you need to download the mapping and then the index

# Install the elasticdump 
npm install elasticdump -g

# Dump the mapping 
elasticdump --input=http://<your_es_server_ip>:9200/index --output=es_mapping.json --type=mapping

# Dump the data
elasticdump --input=http://<your_es_server_ip>:9200/index --output=es_index.json --type=data    

If you want to dump the data on any server I advise you to install esdump through docker. You can get more info from this website Blog Link

You can simply use slash (\) if you have multiple lines for your lambda function

Example:

mx = lambda x, y: x if x > y \
     else y
print(mx(30, 20))

Output: 30

Create a shortcut of anaconda prompt onto desktop or taskbar, and then in the properties of that shortcut make sure u modify the last path in "Target:" to the path of ur environment:

C:\Users\BenBouali\Anaconda3\ WILL CHANGE INTO C:\Users\BenBouali\Anaconda3\envs\tensorflow-gpu

preview

and this way u can use that shortcut to open a certain environment when clicking it, you can add it to ur path too and now you'll be able to run it from windows run box by just typing in the name of the shortcut.

Just assign row to a particular index, using loc:

 df.loc[-1] = [2, 3, 4]  # adding a row
 df.index = df.index + 1  # shifting index
 df = df.sort_index()  # sorting by index

And you get, as desired:

    A  B  C
 0  2  3  4
 1  5  6  7
 2  7  8  9

Modern browsers will take script tags in the body like so:

<body>
    <script src="scripts/main.js"></script>
</body>

Basically, it means that the script will be loaded once the page has finished, which may be useful in certain cases (namely DOM manipulation). However, I highly recommend you take the same script and put it in the head tag with "defer", as it will give the same effect.

<head>
    <script src="scripts/main.js" defer></script>
</head>

There are answers with big number of votes, but when I read your question, I thought you wanted to know the directory where the script is, not that where the script is running. You can get the information with powershell's auto variables

$PSScriptRoot - the directory where the script exists, not the target directory the script is running in
$PSCommandPath - the full path of the script

For example, I have $profile script that finds visual studio solution file and start it. I wanted to store the full path, once a solution file is started. But I wanted to save the file where the original script exists. So I used $PsScriptRoot.

String is present in package java.lang which is imported by default in all java programs.

I realize there are dozens of answers here. I want to share my solution, which ensures true private variables in ES6 classes and in older JS.

var MyClass = (function() {
    var $ = new WeakMap();
    function priv(self) {
       var r = $.get(self);
       if (!r) $.set(self, r={});
       return r;
    }

    return class { /* use $(this).prop inside your class */ } 
}();

Privacy is ensured by the fact that the outside world don't get access to $.

When the instance goes away, the WeakMap will release the data.

This definitely works in plain Javascript, and I believe they work in ES6 classes but I haven't tested that $ will be available inside the scope of member methods.

This should work

top5 = array[:5] 

Using standard C++ calling (note that you should use namespace std for cout or add using namespace std;)

#include <iostream>

int main()
{
    std::cout<<"Hello World!\n";
    return 0;
}

I'm going to assume compiling the QuickFix package does not produce a setup.py file, but rather only compiles the Python bindings and relies on make install to put them in the appropriate place.

In this case, a quick and dirty fix is to compile the QuickFix source, locate the Python extension modules (you indicated on your system these end with a .so extension), and add that directory to your PYTHONPATH environmental variable e.g., add

export PYTHONPATH=~/path/to/python/extensions:PYTHONPATH

or similar line in your shell configuration file.

A more robust solution would include making sure to compile with ./configure --prefix=$HOME/.local. Assuming QuickFix knows to put the Python files in the appropriate site-packages, when you do make install, it should install the files to ~/.local/lib/pythonX.Y/site-packages, which, for Python 2.6+, should already be on your Python path as the per-user site-packages directory.

If, on the other hand, it did provide a setup.py file, simply run

python setup.py install --user

for Python 2.6+.

The .Elements operation returns a LIST of XElements - but what you really want is a SINGLE element. Add this:

XElement Contacts = (from xml2 in XMLDoc.Elements("Contacts").Elements("Node")
                    where xml2.Element("ID").Value == variable
                    select xml2).FirstOrDefault();

This way, you tell LINQ to give you the first (or NULL, if none are there) from that LIST of XElements you're selecting.

Here is a everything you need to know about whitespace in regular expressions:

• [[:blank:]] Space or tab only
• [[:space:]] Whitespace
• \s Any whitespace character
• \v Vertical whitespace
• \h Horizontal whitespace
• x Ignore whitespace

• If you're using Eclipse, you can also try out JAXB Eclipse Plug-In

• You can find more information about XJC Binding Compiler that comes with the jdk installation over here: xjc: Java™ Architecture for XML Binding -Binding Compiler

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

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

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

now you dont need CustomImageView Class anymore.

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

hope this help..

Not sure why this isn't implemented directly in R, but this answer is essentially the same as Andrii's and Wordsforthewise, I just turned into a function for the sake of convenience if somebody uses it a lot like me.

  return(1- sum((preds - actual) ^ 2)/sum((actual - mean(actual))^2))
}

1. Use npm/bower to install bootstrap if you want to recompile it/change less files/test. With grunt it would be easier to do this, as shown on http://getbootstrap.com/getting-started/#grunt. If you only want to add precompiled libraries feel free to manually include files to project.

2. No, you have to do this by yourself or use separate grunt tool. For example 'grunt-contrib-concat' How to concatenate and minify multiple CSS and JavaScript files with Grunt.js (0.3.x)

From ISO14882:2011(e) 5.6-4:

The binary / operator yields the quotient, and the binary % operator yields the remainder from the division of the first expression by the second. If the second operand of / or % is zero the behavior is undefined. For integral operands the / operator yields the algebraic quotient with any fractional part discarded; if the quotient a/b is representable in the type of the result, (a/b)*b + a%b is equal to a.

The rest is basic math:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

Note that

If both operands are nonnegative then the remainder is nonnegative; if not, the sign of the remainder is implementation-defined.

from ISO14882:2003(e) is no longer present in ISO14882:2011(e)

you just use the :nth-child(num) in css for add the colspan like

 <style>
 div.table
  {
  display:table;
  width:100%;
  }
 div.table-row
  {
   display:table-row;
  }
 div.table-td
 {
  display:table-cell;
 }
 div.table-row:nth-child(1)
 {
  display:block;
 }
</style>
<div class="table>
    <div class="table-row">test</div>
    <div class="table-row">
      <div class="table-td">data1</div>
      <div class="table-td">data2</div>
    </div>
</div>

Another option would be to create a custom function generating the equation using dplyr and broom libraries:

get_formula <- function(model) {
  
  broom::tidy(model)[, 1:2] %>%
    mutate(sign = ifelse(sign(estimate) == 1, ' + ', ' - ')) %>% #coeff signs
    mutate_if(is.numeric, ~ abs(round(., 2))) %>% #for improving formatting
    mutate(a = ifelse(term == '(Intercept)', paste0('y ~ ', estimate), paste0(sign, estimate, ' * ', term))) %>%
    summarise(formula = paste(a, collapse = '')) %>%
    as.character
  
}

lm(y ~ x, data = df) -> model
get_formula(model)
#"y ~ 6.22 + 3.16 * x"

scales::percent(summary(model)$r.squared, accuracy = 0.01) -> r_squared

Now we need to add the text to the plot:

p + 
  geom_text(x = 20, y = 300,
            label = get_formula(model),
            color = 'red') +
  geom_text(x = 20, y = 285,
            label = r_squared,
            color = 'blue')

     )

But it's considered bad practice by some (bash FAQ and irc freenode #bash FAQ authors). It's recommended to use:

Another understated reason for not using a singleton DbContext, even in a single threaded single user application, is because of the identity map pattern it uses. It means that every time you retrieve data using query or by id, it will keep the retrieved entity instances in cache. The next time you retrieve the same entity, it will give you the cached instance of the entity, if available, with any modifications you have done in the same session. This is necessary so the SaveChanges method does not end up with multiple different entity instances of the same database record(s); otherwise, the context would have to somehow merge the data from all those entity instances.

The reason that is a problem is a singleton DbContext can become a time bomb that could eventually cache the whole database + the overhead of .NET objects in memory.

There are ways around this behavior by only using Linq queries with the .NoTracking() extension method. Also these days PCs have a lot of RAM. But usually that is not the desired behavior.

What worked for me was downgrading from EF 6.1.3 to EF 6.1.1.

In Visual Studios 2012+ head over to:

Tools - Nuget Package Manager - Package Manager Console`

Then enter:

Install-Package EntityFramework.SqlServerCompact -Version 6.1.1

I did not have to uninstall EF 6.1.3 first because the command above already does that.

In addition, I don't know if it did something, but I also installed SQL Server CE in my project.

Here's the link to the solution I found:

http://www.itorian.com/2014/11/no-entity-framework-provider-found-for.html

This code should work reasonably well:

public static File createTempDir() {
    final String baseTempPath = System.getProperty("java.io.tmpdir");

    Random rand = new Random();
    int randomInt = 1 + rand.nextInt();

    File tempDir = new File(baseTempPath + File.separator + "tempDir" + randomInt);
    if (tempDir.exists() == false) {
        tempDir.mkdir();
    }

    tempDir.deleteOnExit();

    return tempDir;
}

C# - serialData is ReceivedEventHandler in TextBox.

SerialPort sData = sender as SerialPort;
string recvData = sData.ReadLine();

serialData.Invoke(new Action(() => serialData.Text = String.Concat(recvData)));

Now Visual Studio drops my lines. TextBox, of course, had all the correct options on.

Serial:

Serial.print(rnd);
Serial.( '\n' );  //carriage return

I think Paul Tomblin's answer may be wasteful in case coll is already a list, because it will create a new list and copy all elements. If coll contains many elemeents, this may take a long time.

My suggestion is:

List list;
if (coll instanceof List)
  list = (List)coll;
else
  list = new ArrayList(coll);
Collections.sort(list);

To select items (options) with unique ids like in here:

<select
    ng-model="foo" 
    ng-options="bar as bar.title for bar in bars track by bar.id">
</select>

I'm using this:

element(by.css('[value="' + neededBarId+ '"]')).click();

In MongoDB To insert Json array data from file(from particular location from a system / pc) using mongo shell command. While executing below command, command should be in single line.

var file = cat('I:/data/db/card_type_authorization.json'); var o = JSON.parse(file); db.CARD_TYPE_AUTHORIZATION.insert(o);

JSON File: card_type_authorization.json

"code": "visa",
"position": 1,
"description": "Visa",

    "description": "Mastercard",
    "isVertualCard": false,

I managed to solve this in the Request handling code following advice from 'monsur'.

string origin = WebOperationContext.Current.IncomingRequest.Headers.Get("Origin");

WebOperationContext.Current.OutgoingResponse.Headers.Add("Access-Control-Allow-Origin", origin);

WinPython is an open-source distribution that has 64-bit NumPy and SciPy.

I use this solution for responsive boxes of different rations:

HTML:

<div class="box ratio1_1">
  <div class="box-content">
            ... CONTENT HERE ...
  </div>
</div>

CSS:

.box-content {
  width: 100%; height: 100%;
  top: 0;right: 0;bottom: 0;left: 0;
  position: absolute;
}
.box {
  position: relative;
  width: 100%;
}
.box::before {
    content: "";
    display: block;
    padding-top: 100%; /*square for no ratio*/
}
.ratio1_1::before { padding-top: 100%; }
.ratio1_2::before { padding-top: 200%; }
.ratio2_1::before { padding-top: 50%; }
.ratio4_3::before { padding-top: 75%; }
.ratio16_9::before { padding-top: 56.25%; }

In Java x ^ y is an XOR operation.

Try placing $PATH at the end.

export PATH=/usr/local/git/bin:/usr/local/bin:$PATH

Some 3rd party component vendors like Infragistics or Syncfusion provide very good Excel export capabilities that do not require Microsoft Excel to be installed.

Since these vendors also provide advanced UI grid components, these components are particularly handy if you want the style and layout of an excel export to mimic the current state of a grid in the user interface of your application.

If your export is intended to be executed server side with emphasis on the data to be exported and with no link to the UI, then I would go for one of the free open source options (e.g. ExcelLibrary).

I have previously been involved with projects that attempted to use server side automation on the Microsoft Office suite. Based on this experience I would strongly recommend against that approach.

You can iterate over "a file", which produces lines, including the trailing newline character. To make a "virtual file" out of a string, you can use StringIO:

import io  # for Py2.7 that would be import cStringIO as io

for line in io.StringIO(foo):
    print(repr(line))

JSON doesn't require you to do that, it allows you to do that. It also allows you to use "\u0061" for "A", but it's not required. Allowing \/ helps when embedding JSON in a <script> tag, which doesn't allow </ inside strings, like Seb points out.

Some of Microsoft's ASP.NET Ajax/JSON API's use this loophole to add extra information, e.g., a datetime will be sent as "\/Date(milliseconds)\/". (Yuck)

The parser is having trouble concatenating your string. Try this:

write-host 'value is : '$i' '$($ds.Tables[1].Rows[$i][0])

Edit: Using double quotes might also be clearer since you can include the expressions within the quoted string:

write-host "value is : $i $($ds.Tables[1].Rows[$i][0])"

As of Python 3.2+, you can also accomplish this using the from_bytes native int method:

file_size = int.from_bytes(fin.read(2), byteorder='big')

Note that this function requires you to specify whether the number is encoded in big- or little-endian format, so you will have to determine the endian-ness to make sure it works correctly.

That way you haven't installed pip, you installed just the easy_install i.e. setuptools.

First you should remove all the packages you installed with easy_install using (see uninstall):

easy_install -m PackageName

This includes pip if you installed it using easy_install pip.

After this you remove the setuptools following the instructions from here:

If setuptools package is found in your global site-packages directory, you may safely remove the following file/directory:

setuptools-*.egg

If setuptools is installed in some other location such as the user site directory (eg: ~/.local, ~/Library/Python or %APPDATA%), then you may safely remove the following files:

pkg_resources.py
easy_install.py
setuptools/
setuptools-*.egg-info/

I was not able to get the createReadStream/createWriteStream method working for some reason, but using the fs-extra npm module it worked right away. I am not sure of the performance difference though.

npm install --save fs-extra

var fs = require('fs-extra');

fs.copySync(path.resolve(__dirname, './init/xxx.json'), 'xxx.json');

You use ttk.Frame, bg option does not work for it. You should create style and apply it to the frame.

from tkinter import *
from tkinter.ttk import * 

root = Tk()

s = Style()
s.configure('My.TFrame', background='red')

mail1 = Frame(root, style='My.TFrame')
mail1.place(height=70, width=400, x=83, y=109)
mail1.config()
root.mainloop()

Passing data from PHP is easy, you can generate JavaScript with it. The other way is a bit harder - you have to invoke the PHP script by a Javascript request.

An example (using traditional event registration model for simplicity):

<!-- headers etc. omitted -->
<script>
function callPHP(params) {
    var httpc = new XMLHttpRequest(); // simplified for clarity
    var url = "get_data.php";
    httpc.open("POST", url, true); // sending as POST

    httpc.onreadystatechange = function() { //Call a function when the state changes.
        if(httpc.readyState == 4 && httpc.status == 200) { // complete and no errors
            alert(httpc.responseText); // some processing here, or whatever you want to do with the response
        }
    };
    httpc.send(params);
}
</script>
<a href="#" onclick="callPHP('lorem=ipsum&foo=bar')">call PHP script</a>
<!-- rest of document omitted -->

Whatever get_data.php produces, that will appear in httpc.responseText. Error handling, event registration and cross-browser XMLHttpRequest compatibility are left as simple exercises to the reader ;)

TLS 1.2 is only supported since OpenSSL 1.0.1 (see the Major version releases section), you have to update your OpenSSL.

It is not necessary to set the CURLOPT_SSLVERSION option. The request involves a handshake which will apply the newest TLS version both server and client support. The server you request is using TLS 1.2, so your php_curl will use TLS 1.2 (by default) as well if your OpenSSL version is (or newer than) 1.0.1.

Apache Camel is a Java framework for Enterprise integration. Eg:- if you are building a web application which interacts with many vendor API's we can use the camel as the External integration tool. We can do more with it based on the use case. Camel in Action from Manning publications is a great book for learning Camel. The integrations can be defined as below.

Java DSL

from("jetty://0.0.0.0:8080/searchProduct").routeId("searchProduct.products").threads()
    .log(LoggingLevel.INFO, "searchProducts request Received with body: ${body}")
    .bean(Processor.class, "createSearchProductsRequest").removeHeaders("CamelHttp*")
    .setHeader(Exchange.HTTP_METHOD, constant(org.apache.camel.component.http4.HttpMethods.POST))
    .to("http4://" + preLiveBaseAPI + searchProductsUrl + "?apiKey=" + ApiKey
                    + "&bridgeEndpoint=true")
    .bean(Processor.class, "buildResponse").log(LoggingLevel.INFO, "Search products finished");

This is to just create a REST API endpoint which in turn calls an external API and sends the request back

Spring DSL

<route id="GROUPS-SHOW">
    <from uri="jetty://0.0.0.0:8080/showGroups" />
    <log loggingLevel="INFO" message="Reqeust receviced service to fetch groups -> ${body}" />
    <to uri="direct:auditLog" />
    <process ref="TestProcessor" />
</route>

Coming to your questions

1. What exactly is it? Ans:- It is a framework which implements Enterprise integration patterns
2. How does it interact with an application written in Java? Ans:- it can interact with any available protocols like http, ftp, amqp etc
3. Is it something that goes together with the server? Ans:- It can be deployed in a container like tomcat or can be deployed independently as a java process
4. Is it an independent program? Ans:- It can be.

Hope it helps

By default

1. Primitives are passed by value. Unlikely to Java, string is primitive in PHP
2. Arrays of primitives are passed by value
3. Objects are passed by reference

4. Arrays of objects are passed by value (the array) but each object is passed by reference.

   <?php
   $obj=new stdClass();
   $obj->field='world';
   
   $original=array($obj);
   
   
   function example($hello) {
       $hello[0]->field='mundo'; // change will be applied in $original
       $hello[1]=new stdClass(); // change will not be applied in $original
       $
   }
   
   example($original);
   
   var_dump($original);
   // array(1) { [0]=> object(stdClass)#1 (1) { ["field"]=> string(5) "mundo" } } 
   

Note: As an optimization, every single value is passed as reference until its modified inside the function. If it's modified and the value was passed by reference then, it's copied and the copy is modified.

If you code for iOS 13.0 or later and want a timestamp, then you can use:

let currentDate = NSDate.now

Just finished coding data storage for my current project. Here is my 5 cents.

I started with binary serialization. It was slow (about 30 sec for load of 100,000 objects) and it was creating a pretty big file on the disk as well. However, it took me a few lines of code to implement and I got my all storage needs covered. To get better performance I moved on custom serialization. Found FastSerialization framework by Tim Haynes on Code Project. Indeed it is a few times faster (got 12 sec for load, 8 sec for save, 100K records) and it takes less disk space. The framework is built on the technique outlined by GalacticJello in a previous post.

Then I moved to SQLite and was able to get 2 sometimes 3 times faster performance – 6 sec for load and 4 sec for save, 100K records. It includes parsing ADO.NET tables to application types. It also gave me much smaller file on the disk. This article explains how to get best performance out of ADO.NET: http://sqlite.phxsoftware.com/forums/t/134.aspx. Generating INSERT statements is a very bad idea. You can guess how I came to know about that. :) Indeed, SQLite implementation took me quite a bit of time plus careful measurement of time taking by pretty much every line of the code.

My friend... there is a way but "hack" does not begin to describe it. You have to basically exploit a bug in IE 6 & 7.

Works every time!

Instead of calling window.close(), redirect to another page.

Opening Page:

alert("No whammies!");
window.open("closer.htm", '_self');

Redirect to another page. This fools IE into letting you close the browser on this page.

Closing Page:

<script type="text/javascript">
    window.close();
</script>

Awesome huh?!

I want to contribute to this thread the fastest loop in JavaScript that is cross-browser ! This loop yields over 500% improvement compared to the reverse while loop.

Difference between pointer and reference

A pointer can be initialized to 0 and a reference not. In fact, a reference must also refer to an object, but a pointer can be the null pointer:

int* p = 0;

But we can’t have int& p = 0; and also int& p=5 ;.

In fact to do it properly, we must have declared and defined an object at the first then we can make a reference to that object, so the correct implementation of the previous code will be:

Int x = 0;
Int y = 5;
Int& p = x;
Int& p1 = y;

Another important point is that is we can make the declaration of the pointer without initialization however no such thing can be done in case of reference which must make a reference always to variable or object. However such use of a pointer is risky so generally we check if the pointer is actually is pointing to something or not. In case of a reference no such check is necessary, because we know already that referencing to an object during declaration is mandatory.

Another difference is that pointer can point to another object however reference is always referencing to the same object, let’s take this example:

Int a = 6, b = 5;
Int& rf = a;

Cout << rf << endl; // The result we will get is 6, because rf is referencing to the value of a.

rf = b;
cout << a << endl; // The result will be 5 because the value of b now will be stored into the address of a so the former value of a will be erased

Another point: When we have a template like an STL template such kind of a class template will always return a reference, not a pointer, to make easy reading or assigning new value using operator []:

Std ::vector<int>v(10); // Initialize a vector with 10 elements
V[5] = 5; // Writing the value 5 into the 6 element of our vector, so if the returned type of operator [] was a pointer and not a reference we should write this *v[5]=5, by making a reference we overwrite the element by using the assignment "="

YES, you can Update and Insert into view and that edit will be reflected on the original table....
BUT
1-the view should have all the NOT NULL values on the table
2-the update should have the same rules as table... "updating primary key related to other foreign key.. etc"...

You can also get content such as the first pagagraph via DBPedia which takes Wikipedia content and creates structured information from it (RDF) and makes this available via an API. The DBPedia API is a SPARQL one (RDF-based) but it outputs JSON and it is pretty easy to wrap.

As an example here's a super simple JS library named WikipediaJS that can extract structured content including a summary first paragraph: http://okfnlabs.org/wikipediajs/

You can read more about it in this blog post: http://okfnlabs.org/blog/2012/09/10/wikipediajs-a-javascript-library-for-accessing-wikipedia-article-information.html

The JS library code can be found here: https://github.com/okfn/wikipediajs/blob/master/wikipedia.js

Use where_in()

$ids = array('20', '15', '22', '46', '86');
$this->db->where_in('id', $ids );

Just as a matter of fact:

data_joined = dat1.join(dat2)
print(data_joined)

TextBoxFor: It will render like text input html element corresponding to specified expression. In simple word it will always render like an input textbox irrespective datatype of the property which is getting bind with the control.

EditorFor: This control is bit smart. It renders HTML markup based on the datatype of the property. E.g. suppose there is a boolean property in model. To render this property in the view as a checkbox either we can use CheckBoxFor or EditorFor. Both will be generate the same markup.

What is the advantage of using EditorFor?

As we know, depending on the datatype of the property it generates the html markup. So suppose tomorrow if we change the datatype of property in the model, no need to change anything in the view. EditorFor control will change the html markup automatically.

I tried many formats, but only that worked:

select /*+INDEX(e,dept_idx)*/ * from emp e;

I use SyntaxHighlighter with my Blogger powered blog. The actual site is hosted on my own server rather than Blogger's though (Blogger has an option of ftping posts to your own site), but having your own domain and web hosting only costs a couple of dollars a month.

I've been working on a project called GiySync. It still needs some work, but it's open source and I've been using it every day for a couple of years. I'm also working on a native OS X version I've called GitSyncApp

Right now it's OS X only but it should be easy to add support for Linux, and possibly Windows too.

It works by watching file system events and it uses to git to sync a project folder on your local machine and a server.

I tried the other solutions like osx fuse, Expand Drive, Transmit, several solutions that used rsync, etc. They all work 'OK' for small projects, but if you're working with a lot of code they did not work for me.

A lot of the file system options do caching to improve performance, which is fine, until it's not. Like if you're working with other people and someone else changes the files on the server.

I also ran into issues if I was on a flaky or slow network where I'd end up with empty files. Or file that didn't sync, then the caching got weird; hopefully you committed recently. Using git solves this problem because it checks each commit's integrity.

Two bonus features:

1. You end up with a commit for every save. It's not super useful but if you ever have to go back in time you can.
2. It works with any text editor.

If you enable Query Store on SQL Server 2016 or newer you can use the following query to get last SP execution. The history depends on the Query Store Configuration.

SELECT 
      ObjectName = '[' + s.name + '].[' + o.Name  + ']'
    , LastModificationDate  = MAX(o.modify_date)
    , LastExecutionTime     = MAX(q.last_execution_time)
FROM sys.query_store_query q 
    INNER JOIN sys.objects o
        ON q.object_id = o.object_id
    INNER JOIN sys.schemas s
        ON o.schema_id = s.schema_id
WHERE o.type IN ('P')
GROUP BY o.name , + s.name 

     @Html.DropDownListFor(m => m.SelectedValue,Your List,"ID","Values")

Here Value is that object of model where you want to save your Selected Value

It happened for me also and the reason was selecting inappropriate combination of tomcat and Dynamic web module version while creating project in eclipse. I selected Tomcat v9.0 along with Dynamic web module version 3.1 and eclipse was not able to resolve the HttpServlet type. When used Tomcat 7.0 along with Dynamic web module version 7.0, eclipse was automatically able to resolve the HttpServlet type.

Related question Dynamic Web Module option in Eclipse

To check which version of tomcat should be used along with different versions of the Servlet and JSP specifications refer http://tomcat.apache.org/whichversion.html

Ok just to let you know what's happened then, i fixed using some new classes as Acyra says above:

.top5 { margin-top:5px; }
.top7 { margin-top:7px; }
.top10 { margin-top:10px; }
.top15 { margin-top:15px; }
.top17 { margin-top:17px; }
.top30 { margin-top:30px; }

whenever i want i do <div class="row top7"></div>

for better responsive you can add margin-top:7% instead of 5px for example :D

Never mind -- I'm an idiot. I just needed <xsl:value-of select="/root/Image/node()"/>

to resolve this kind of problem you should add two jar in your dependency POM (if use Maven)

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm</artifactId>
    <version>3.3.1</version>
</dependency>

<dependency>
    <groupId>cglib</groupId>
    <artifactId>cglib</artifactId>
    <version>3.1</version>
</dependency>

I built a general-purpose approach to doing various operations on a merge's commits.

Step One: Add an alias to git by editing ~/.gitconfig:

[alias]
  range = "!. ~/.githelpers && run_on_merge_range"

Step Two: In ~/.githelpers, define a bash function:

run_on_merge_range() {
  cmd=$1; shift
  commit=$1; shift
  range=$(git show $commit | grep Merge: | awk '{print $2 "..." $3}')
  echo "git $cmd $range $@"
  if [ -z $range ]; then
    echo "No merge detected"
    exit 1
  fi
  git $cmd $range $@
}

Step Three: Profit!

git range log <merge SHA> --oneline
git range diff <merge SHA> --reverse -p
git range diff <merge SHA> --name-only

There is probably a LOT of room for improvement here, I just whipped this together to get past an annoying situation. Feel free to mock my bash syntax and/or logic.

@csharptest.net's and Christian Gollhardt's answers are great, thank you very much. But after running this code on production with millions of record, I discovered there is a memory leak. RNGCryptoServiceProvider and Rfc2898DeriveBytes classes are derived from IDisposable but we don't dispose of them. I will write my solution as an answer if someone needs with disposed version.

Use lambda function instead of ternary operator

Example 1

to give the max int

package main

func main() {

    println( func(a,b int) int {if a>b {return a} else {return b} }(1,2) )
}

Example 2

Suppose you have this must(err error) function to handle errors and you want to use it when a condition isn't fulfilled. (enjoy at https://play.golang.com/p/COXyo0qIslP)

package main

import (
    "errors"
    "log"
    "os"
)

// must is a little helper to handle errors. If passed error != nil, it simply panics.
func must(err error) {
    if err != nil {
        log.Println(err)
        panic(err)
    }
}

func main() {

    tmpDir := os.TempDir()
    // Make sure os.TempDir didn't return empty string
    // reusing my favourite `must` helper
    // Isn't that kinda creepy now though?
    must(func() error {
        var err error
        if len(tmpDir) > 0 {
            err = nil
        } else {
            err = errors.New("os.TempDir is empty")
        }
        return err
    }()) // Don't forget that empty parentheses to invoke the lambda.
    println("We happy with", tmpDir)
}

Yes, the solution is to use setTimeout, like this:

var delay = 10000;
var url = "https://stackoverflow.com";
var timeoutID = setTimeout(function() {
    window.location.href = url;
}, delay);

note that the result was stored into timeoutID. If, for whatever reason you need to cancel the order, you just need to call

clearTimeout(timeoutID);

I would not use an array in this case. Instead I would use a StringCollection.

using System.Collections.Specialized;

private StringCollection ColeccionDeCortes(string Path)   
{

    DirectoryInfo X = new DirectoryInfo(Path);

    FileInfo[] listaDeArchivos = X.GetFiles();
    StringCollection Coleccion = new StringCollection();

    foreach (FileInfo FI in listaDeArchivos)
    {
        Coleccion.Add( FI.Name );
    }
    return Coleccion;
}

Dietrich's answer is probably just the thing you need for what you describe, sending bytes, but a closer analogue to the code you've provided for example would be using the bytearray type.

>>> key = bytearray([0x13, 0x00, 0x00, 0x00, 0x08, 0x00])
>>> bytes(key)
b'\x13\x00\x00\x00\x08\x00'
>>> 

/*$mpdf = new mPDF('',    // mode - default ''
 '',    // format - A4, for example, default ''
 0,     // font size - default 0
 '',    // default font family
 15,    // margin_left
 15,    // margin right
 16,     // margin top
 16,    // margin bottom
 9,     // margin header
 9,     // margin footer
 'L');  // L - landscape, P - portrait*/

From the terminal you can simply do a "postgres list clusters":

pg_lsclusters

It will return Postgres version number, cluster names, ports, status, owner, and the location of your data directories and log file.

Rauno Palosaari's solution for Timeout in Seconds Darwin, is an excellent workaround for a UNIX-like OS that does not have GNU tail (it is not specific to Darwin). But, depending on the age of the UNIX-like operating system, the command-line offered is more complex than necessary, and can fail:

lsof -p $pid +r 1m%s -t | grep -qm1 $(date -v+${timeout}S +%s 2>/dev/null || echo INF)

On at least one old UNIX, the lsof argument +r 1m%s fails (even for a superuser):

lsof: can't read kernel name list.

The m%s is an output format specification. A simpler post-processor does not require it. For example, the following command waits on PID 5959 for up to five seconds:

lsof -p 5959 +r 1 | awk '/^=/ { if (T++ >= 5) { exit 1 } }'

In this example, if PID 5959 exits of its own accord before the five seconds elapses, ${?} is 0. If not ${?} returns 1 after five seconds.

It may be worth expressly noting that in +r 1, the 1 is the poll interval (in seconds), so it may be changed to suit the situation.

EXEC proc_name @paramValue1 = 0, @paramValue2 = 'some text';
GO

If the Stored Procedure objective is to perform an INSERT on a table that has an Identity field declared, then the field, in this scenario @paramValue1, should be declared and just pass the value 0, because it will be auto-increment.

Try to reinstall new version of XAMPP. Find "<Directory "C:/xampp/php">" and then change to something like this

<Directory "C:/xampp/php">
    AllowOverride AuthConfig Limit
    Order allow,deny
    Allow from all
    Require all granted
</Directory>

Here's the stuff I ran into:

1) RTFM and install the "Microsoft Visual C++ 2008 SP1 Redistributable Package" mentioned at top of the installation docs. I missed this at first because the Helios instructions are at the end.

2) Close all open editor tabs before opening a class file. Otherwise it's easy to get an outdated editor tab from a previous attempt.

3) Open the class file in the "Java Class File Editor" (not "Java Class File Viewer"). Use "Open With" in the context menu to get the right editor. If pleased with results, make it the default editor in the File Association settings, in Window/Preference General/Editors/File Associations select *.class to open with "Java Class File Editor".

4) This guy recommends installing the Equinox SDK from the Helios update site. I did, but I'm not sure if this was really necessary. Anyone know?

5) If the class files you are trying to view are in an Eclipse Java project, they need to be in the project's build path. Otherwise, an exception ("Not in the build path") will show up in the Eclipse error log, and decompile will fail. I added the class files as a library / class file folder to the build path.

6) Drag/dropping a class file from Windows Explorer or opening it with File/Open File... will not work. In my tests, I gives a "Could not open the editor: The Class File Viewer cannot handle the given input ('org.eclipse.ui.ide.FileStoreEditorInput')." error. That is probably the wrong editor anyways, see 3).

7) After getting the plugin basically running, some files would still not decompile for an unknown reason. This disappeared after closing all tabs, restarting Helios, and trying again.

How about typing document.cookie into the console? It just shows the values, but it's something.

Try this code for to trim a String

Public Function AllTrim(ByVal GeVar As String) As String
    Dim i As Integer
    Dim e As Integer
    Dim NewStr As String = ""
    e = Len(GeVar)
    For i = 1 To e
        If Mid(GeVar, i, 1) <> " " Then
            NewStr = NewStr + Mid(GeVar, i, 1)
        End If
    Next i
    AllTrim = NewStr
    ' MsgBox("alltrim = " & NewStr)
End Function

Why use jQuery for this?

str = "123-4"; 
alert(str.substring(0,str.length - 1));

Of course if you must:

Substr w/ jQuery:

//example test element
 $(document.createElement('div'))
    .addClass('test')
    .text('123-4')
    .appendTo('body');

//using substring with the jQuery function html
alert($('.test').html().substring(0,$('.test').html().length - 1));

I would simply add a new column to the data frame with the name I want and get the data for it from the existing column. like this:

dataf$value=dataf$Article1Order

then I remove the old column! like this:

dataf$Article1Order<-NULL

This code might seem silly! But it works perfectly...

if you're turned off by the extra line, you can use a wrapper function like so:

def with_iter(iterable):
    with iterable as iter:
        for item in iter:
            yield item

for line in with_iter(open('...')):
    ...

in Python 3.3, the yield from statement would make this even shorter:

def with_iter(iterable):
    with iterable as iter:
        yield from iter

The class java.sql.Date is designed to carry only a date without time, so the conversion result you see is correct for this type. You need to use a java.sql.Timestamp to get a full date with time.

java.util.Date newDate = result.getTimestamp("VALUEDATE");

There is a workaround which may help. You may "register" results for each set_fact iteration and then map that results to list:

---
- hosts: localhost
  tasks:
  - name: set fact
    set_fact: foo_item="{{ item }}"
    with_items:
      - four
      - five
      - six
    register: foo_result

  - name: make a list
    set_fact: foo="{{ foo_result.results | map(attribute='ansible_facts.foo_item') | list }}"

  - debug: var=foo

Output:

< TASK: debug var=foo >
 ---------------------
    \   ^__^
     \  (oo)\_______
        (__)\       )\/\
            ||----w |
            ||     ||


ok: [localhost] => {
    "var": {
        "foo": [
            "four", 
            "five", 
            "six"
        ]
    }
}

This is a known bug. flexWrap: 'wrap' didn't work for me but this solution seems to work for most people

Code

<View style={styles.container}>
    <Text>Some text</Text>
</View>

Styles

export default StyleSheet.create({
    container: {
        width: 0,
        flexGrow: 1,
        flex: 1,
    }
});

Click app review and Turn on the Make your app Public toggle. Save changes

You can use beforeShowDay to do this

The following example disables dates 14 March 2013 thru 16 March 2013

var array = ["2013-03-14","2013-03-15","2013-03-16"]

$('input').datepicker({
    beforeShowDay: function(date){
        var string = jQuery.datepicker.formatDate('yy-mm-dd', date);
        return [ array.indexOf(string) == -1 ]
    }
});

Demo: Fiddle

on Android Studio 4.0 and above, you will get an option readily on the IDE,a green run icon to run the related main() class.

Android Studio 0.8.10+ has introduced an incredibly useful tool called Memory Monitor.

What it's good for:

• Showing available and used memory in a graph, and garbage collection events over time.
• Quickly testing whether app slowness might be related to excessive garbage collection events.
• Quickly testing whether app crashes may be related to running out of memory.

Figure 1. Forcing a GC (Garbage Collection) event on Android Memory Monitor

You can have plenty good information on your app's RAM real-time consumption by using it.

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

For me , the error was calling the function useState outside the function default exported

Here is the sequence that worked for me after struggling for several hours:

Assume the bot name is my_bot.

1- Add the bot to the group.
Go to the group, click on group name, click on Add members, in the searchbox search for your bot like this: @my_bot, select your bot and click add.

2- Send a dummy message to the bot.
You can use this example: /my_id @my_bot
(I tried a few messages, not all the messages work. The example above works fine. Maybe the message should start with /)

3- Go to following url: https://api.telegram.org/botXXX:YYYY/getUpdates
replace XXX:YYYY with your bot token

4- Look for "chat":{"id":-zzzzzzzzzz,
-zzzzzzzzzz is your chat id (with the negative sign).

5- Testing: You can test sending a message to the group with a curl:

curl -X POST "https://api.telegram.org/botXXX:YYYY/sendMessage" -d "chat_id=-zzzzzzzzzz&text=my sample text"

If you miss step 2, there would be no update for the group you are looking for. Also if there are multiple groups, you can look for the group name in the response ("title":"group_name").

Hope this helps.

For this you can use limit

select *
from scores
order by score desc
limit 10

If performance is important (when is it not ;-) look for an index on score.

Starting with version 8.4, you can also use the standard (SQL:2008) fetch first

select *
from scores
order by score desc
fetch first 10 rows only

As @Raphvanns pointed out, this will give you the first 10 rows literally. To remove duplicate values, you have to select distinct rows, e.g.

select distinct *
from scores
order by score desc
fetch first 10 rows only

Using an absolute or relative string as the filename.

name_of_file = input("What is the name of the file: ")
completeName = '/home/user/Documents'+ name_of_file + ".txt"
file1 = open(completeName , "w")
toFile = input("Write what you want into the field")
file1.write(toFile)
file1.close()

    String stitolo = titolorecuperato.getText().toString();

    Button btnHome = (Button) findViewById(R.id.button);

    btnHome.setOnClickListener(new View.OnClickListener() {

       @Override

same thing as Nic007 said before.

You do need to write code inside "onCreate" method. Sorry me too for the indent... (first comment here)

I know this is an old question ... anyway ... if you want to keep your xml nice and simple you can extend TableLayout and override dispatchDraw to do some custom drawing.

Here is a quick and dirty implementation that draws a rectangle around the table view as well as horizontal and verticals bars:

public class TableLayoutEx extends TableLayout {
    private Paint linePaint = null;
    private Rect tableLayoutRect;

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

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

    @Override
    protected void onSizeChanged(int w, int h, int oldw, int oldh) {
        super.onSizeChanged(w, h, oldw, oldh);

        float strokeWidth = this.getContext().getResources().getDisplayMetrics().scaledDensity * 1;
        linePaint = new Paint(0);
        linePaint.setColor(0xff555555);
        linePaint.setStrokeWidth(strokeWidth);
        linePaint.setStyle(Paint.Style.STROKE);

        Rect rect = new Rect();           
        int paddingTop= getPaddingTop();

        this.getDrawingRect(rect);
        tableLayoutRect = new Rect(rect.left, rect.top + paddingTop, rect.right, rect.bottom);
    }

    @Override
    protected void dispatchDraw(Canvas canvas) {
        super.dispatchDraw(canvas);

        Rect rect = new Rect();

        if (linePaint != null) {
            canvas.drawRect(tableLayoutRect, linePaint);
            float y = tableLayoutRect.top;
            for (int i = 0; i < getChildCount() - 1; i++) {
                if (getChildAt(i) instanceof TableRow) {
                    TableRow tableRow = (TableRow) getChildAt(i);
                    tableRow.getDrawingRect(rect);
                    y += rect.height();
                    canvas.drawLine(tableLayoutRect.left, y, tableLayoutRect.right, y, linePaint);
                    float x = tableLayoutRect.left;
                    for (int j = 0; j < tableRow.getChildCount() - 1; j++) {
                        View view = tableRow.getChildAt(j);
                        if (view != null) {
                            view.getDrawingRect(rect);
                            x += rect.width();
                            canvas.drawLine(x, tableLayoutRect.top, x, tableLayoutRect.bottom, linePaint);
                        }
                    }
                }
            }
        }
    }
}

xml example with the third column wrapping text:

<com.YOURPACKAGE.TableLayoutEx
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:shrinkColumns="2"
    android:paddingTop="6dp">

    <TableRow>
        <TextView
            android:text="@string/my_text_0_0"
            android:padding="@dimen/my_padding"/>
        <TextView
            android:text="@string/my_text_0_1"
            android:padding="@dimen/my_padding"/>
        <TextView                   
            android:text="@string/my_text_0_2_to_wrap"
            android:padding="@dimen/my_padding"/>
    </TableRow>

    <!--more table rows here-->

</com.YOURPACKAGE.TableLayoutEx>

true and false are not meant to be strings in this context.

You want the literal true and false Boolean values.

startButton.disabled = true;

startButton.disabled = false;

The reason it sort of works (disables the element) is because a non empty string is truthy. So assigning 'false' to the disabled property has the same effect of setting it to true.

You may try the TryParse method which allows you to parse a string into an integer and return a boolean result indicating the success or failure of the operation.

int distance;
if (int.TryParse(txtEvDistance.Text, out distance))
{
    // it's a valid integer => you could use the distance variable here
}

In pycharm 2019.2, you can simply do this to run all tests:

1. Run > Edit Configurations > Add pytest
2. Set options as shown in following screenshot
3. Click on Debug (or run pytest using e.g. hotkeys Shift+Alt+F9)

For a higher integration of pytest into pycharm, see https://www.jetbrains.com/help/pycharm/pytest.html

In my case, my server was configured to work only in https mode, and error occured when I try to access http mode. So changing http://my-service to https://my-service helped.

try:
    parts = ip.split('.')
    return len(parts) == 4 and all(0 <= int(part) < 256 for part in parts)
except ValueError:
    return False # one of the 'parts' not convertible to integer
except (AttributeError, TypeError):
    return False # `ip` isn't even a string

Try this:

<form method="post" action="check.php">
    <select name="website_string">
        <option value="" selected="selected"></option>
        <option VALUE="abc"> ABC</option>
        <option VALUE="def"> def</option>
        <option VALUE="hij"> hij</option>
    </select>
    <input TYPE="submit" name="submit" />
</form>

Both your select control and your submit button had the same name attribute, so the last one used was the submit button when you clicked it. All other syntax errors aside.

check.php

<?php
    echo $_POST['website_string'];
?>

Obligatory disclaimer about using raw $_POST data. Sanitize anything you'll actually be using in application logic.

-- c#.net

NORMALIZE this.WindowState = FormWindowState.Normal;

this.WindowState = FormWindowState.Minimized;

This is even more frustrating because now (.net 5) MS have marked many (all) of their methods that take a string instead of a Uri as obsolete.

Anyway, probably a better way to manipulate relative Uris is to give it what it wants:

var requestUri = new Uri("x://x").MakeRelativeUri(
   new UriBuilder("x://x") { Path = path, Query = query }.Uri);

You can use the other answers to actually build the query string.

I know this question has been answered a while ago but this could help.

What do the following terms mean?

SaaS

Software as a Service - Essentially, any application that runs with its contents from the cloud is referred to as Software as a Service, As long as you do not own it.

Some examples are Gmail, Netflix, OneDrive etc.

AUDIENCE: End users, everybody

IaaS

Infrastructure as a Service means that the provider allows a portion of their computing power to its customers, It is purchased by the potency of the computing power and they are bundled in Virtual Machines. A company like Google Cloud platform, AWS, Alibaba Cloud can be referred to as IaaS providers because they sell processing powers (servers, storage, networking) to their users in terms of Virtual Machines.

AUDIENCE: IT professionals, System Admins

PaaS

Platform as a Service is more like the middle-man between IaaS and SaaS, Instead of a customer having to deal with the nitty-gritty of servers, networks and storage, everything is readily available by the PaaS providers. Essentially a development environment is initialized to make building applications easier.

Examples would be Heroku, AWS Elastic Beanstalk, Google App Engine etc

AUDIENCE: Software developers.

There are various cloud services available today, such as Amazon's EC2 and AWS, Apache Hadoop, Microsoft Azure and many others. Which category does each belong to and why?

Amazon EC2 and AWS - is an Infrastructure as a Service because you'll need System Administrators to manage the working process of your operating system. There is no abstraction to build a fully featured app ordinarily. Microsoft Azure would also fall under this category following the aforementioned guidelines.

I really haven't used Apache Hadoop, so I really cannot say.

I simply added in first function

parentThis = this;

and use parentThis in subfunction. Why? Because in JavaScript, objects are soft. A new member can be added to a soft object by simple assignment (not like ie. Java where classical objects are hard. The only way to add a new member to a hard object is to create a new class) More on this here: http://www.crockford.com/javascript/inheritance.html

And also at the end you don't have to kill or destroy the object. Why I found here: http://bytes.com/topic/javascript/answers/152552-javascript-destroy-object

Hope this helps

I don't think there's any reason to add this function to JQuery's namespace. Why not just define the method by itself:

function showMessage(msg) {
   alert(msg);
};

<input type="button" value="ahaha" onclick="showMessage('msg');" />

UPDATE: With a small change to how your method is defined I can get it to work:

<html>
<head>
 <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
 <script language="javascript">
    // define the function within the global scope
    $.fn.MessageBox = function(msg) {
        alert(msg);
    };

    // or, if you want to encapsulate variables within the plugin
    (function($) {
        $.fn.MessageBoxScoped = function(msg) {
            alert(msg);
        };
    })(jQuery); //<-- make sure you pass jQuery into the $ parameter
 </script>
</head>
<body>
 <div class="Title">Welcome!</div>
 <input type="button" value="ahaha" id="test" onClick="$(this).MessageBox('msg');" />
</body>
</html>

I came to the same problem and tried all methods on internet, and finally worked it out by accident. May you could try this(see in the picture)

Use the enumerate built-in function: http://docs.python.org/library/functions.html#enumerate

To Enable WiFi:

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(true);

To Disable WiFi:

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(false);

Note: To access with WiFi state, we have to add following permissions inside the AndroidManifest.xml file:

android.permission.ACCESS_WIFI_STATE
android.permission.UPDATE_DEVICE_STATS 
android.permission.CHANGE_WIFI_STATE

This is the C ternary operator (Objective-C is a superset of C):

label.frame = (inPseudoEditMode) ? kLabelIndentedRect : kLabelRect;

is semantically equivalent to

if(inPseudoEditMode) {
 label.frame = kLabelIndentedRect;
} else {
 label.frame = kLabelRect;
}

The ternary with no first element (e.g. variable ?: anotherVariable) means the same as (valOrVar != 0) ? valOrVar : anotherValOrVar

$("#pageCSS").attr('href', './css/new_css.css');

You can use gdb for this like objdump.

This excerpt is taken from http://sources.redhat.com/gdb/current/onlinedocs/gdb_9.html#SEC64

Here is an example showing mixed source+assembly for Intel x86:

End of assembler dump.

This problem appear if two software use same port for connecting to the server
try to close the port by cmd according to your operating system
then reboot your Android studio or your Eclipse or your Software.

You can deserialize directly to a list by using the TypeReference wrapper. An example method:

public static <T> T fromJSON(final TypeReference<T> type,
      final String jsonPacket) {
   T data = null;

   try {
      data = new ObjectMapper().readValue(jsonPacket, type);
   } catch (Exception e) {
      // Handle the problem
   }
   return data;
}

And is used thus:

final String json = "";
Set<POJO> properties = fromJSON(new TypeReference<Set<POJO>>() {}, json);

TypeReference Javadoc

From W3C Document Object Model (Core) Level 1 specification (bold is mine):

Most of the APIs defined by this specification are interfaces rather than classes. That means that an actual implementation need only expose methods with the defined names and specified operation, not actually implement classes that correspond directly to the interfaces. This allows the DOM APIs to be implemented as a thin veneer on top of legacy applications with their own data structures, or on top of newer applications with different class hierarchies. This also means that ordinary constructors (in the Java or C++ sense) cannot be used to create DOM objects, since the underlying objects to be constructed may have little relationship to the DOM interfaces. The conventional solution to this in object-oriented design is to define factory methods that create instances of objects that implement the various interfaces. In the DOM Level 1, objects implementing some interface "X" are created by a "createX()" method on the Document interface; this is because all DOM objects live in the context of a specific Document.

AFAIK, you can not create any XmlNode (XmlElement, XmlAttribute, XmlCDataSection, etc) except XmlDocument from a constructor.

Moreover, note that you can not use XmlDocument.AppendChild() for nodes that are not created via the factory methods of the same document. In case you have a node from another document, you must use XmlDocument.ImportNode().

Phonegap is pretty slow: clicking a button can take up to 3 sec to display the next screen. iscroll is slow and jumpy.

There other funny bugs and issues that i was able to overcome, but in total - not fully matured.

EDIT: Per Grumpy comment, it is not Phonegap who is actually slow, it is the JS/Browser native engine

1. An Object file is the compiled file itself. There is no difference between the two.

2. An executable file is formed by linking the Object files.

3. Object file contains low level instructions which can be understood by the CPU. That is why it is also called machine code.

4. This low level machine code is the binary representation of the instructions which you can also write directly using assembly language and then process the assembly language code (represented in English) into machine language (represented in Hex) using an assembler.

Here's a typical high level flow for this process for code in High Level Language such as C

--> goes through pre-processor

--> to give optimized code, still in C

--> goes through compiler

--> to give assembly code

--> goes through an assembler

--> to give code in machine language which is stored in OBJECT FILES

--> goes through Linker

--> to get an executable file.

This flow can have some variations for example most compilers can directly generate the machine language code, without going through an assembler. Similarly, they can do the pre-processing for you. Still, it is nice to break up the constituents for a better understanding.

Most of the answers for this question can not helped me in 2020.

This notification from download site of Oracle may be the reason:

Important Oracle JDK License Update

The Oracle JDK License has changed for releases starting April 16, 2019.

I try to google a little bit and those tutorials below helped me a lot.

1. Remove completely the previous version of JVM installed on your PC.

   sudo update-alternatives --remove-all java
   sudo update-alternatives --remove-all javac
   sudo update-alternatives --remove-all javaws
   
   # /usr/lib/jvm/jdk1.7.0 is the path you installed the previous version of JVM on your PC
   sudo rm -rf /usr/lib/jvm/jdk1.7.0 
   

   Check to see whether java is uninstalled or not

   java -version
   

2. Install Java 8 JDK.

   • Download Java 8 from Oracle's website. The version being used is 1.8.0_251. Pay attention to this value, you may need it to edit commands in this answer when Java 8 is upgraded to another version.
   • Extract the compressed file to the place where you want to install.

   cd /usr/lib/jvm
   sudo tar xzf ~/Downloads/jdk-8u251-linux-x64.tar.gz
   

   • Edit environment file

   sudo gedit /etc/environment
   

   • Edit the PATH's value by appending the string below to the current value

   :/usr/lib/jvm/jdk1.8.0_251/bin:/usr/lib/jvm/jdk1.8.0_251/jre/bin
   

   • Append those strings to the environment file

   J2SDKDIR="/usr/lib/jvm/jdk1.8.0_251"
   J2REDIR="/usr/lib/jvm/jdk1.8.0_251/jre"
   JAVA_HOME="/usr/lib/jvm/jdk1.8.0_251"
   

   • Complete the installation by running commands below

   sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0_251/bin/java" 0
   sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0_251/bin/javac" 0
   sudo update-alternatives --set java /usr/lib/jvm/jdk1.8.0_251/bin/java
   sudo update-alternatives --set javac /usr/lib/jvm/jdk1.8.0_251/bin/javac
   
   update-alternatives --list java
   update-alternatives --list javac
   

Keep in mind that loading the page has more than one stage. Btw, this is pure JavaScript

"DOMContentLoaded"

This event is fired when the initial HTML document has been completely loaded and parsed, without waiting for stylesheets, images, and subframes to finish loading. At this stage you could programmatically optimize loading of images and css based on user device or bandwidth speed.

Executes after DOM is loaded (before img and css):

document.addEventListener("DOMContentLoaded", function(){
    //....
});

Note: Synchronous JavaScript pauses parsing of the DOM. If you want the DOM to get parsed as fast as possible after the user requested the page, you could turn your JavaScript asynchronous and optimize loading of stylesheets

"load"

A very different event, load, should only be used to detect a fully-loaded page. It is an incredibly popular mistake to use load where DOMContentLoaded would be much more appropriate, so be cautious.

Exectues after everything is loaded and parsed:

window.addEventListener("load", function(){
    // ....
});

MDN Resources:

https://developer.mozilla.org/en-US/docs/Web/Events/DOMContentLoaded https://developer.mozilla.org/en-US/docs/Web/Events/load

MDN list of all events:

https://developer.mozilla.org/en-US/docs/Web/Events

Technical differences are a consequence of the goal of each one (OpenJDK is meant to be the reference implementation, open to the community, while Oracle is meant to be a commercial one)

They both have "almost" the same code of the classes in the Java API; but the code for the virtual machine itself is actually different, and when it comes to libraries, OpenJDK tends to use open libraries while Oracle tends to use closed ones; for instance, the font library.

#!/bin/bash

variable=`ps -ef | grep "port 10 -" | grep -v "grep port 10 -" | awk '{printf $12}'`
echo $variable

Notice that there's no space after the equal sign.

You can also use $() which allows nesting and is readable.

The following works well in a .php file.

<php? /*your block you want commented out*/ ?>

You need rawQuery method.

Example:

private final String MY_QUERY = "SELECT * FROM table_a a INNER JOIN table_b b ON a.id=b.other_id WHERE b.property_id=?";

db.rawQuery(MY_QUERY, new String[]{String.valueOf(propertyId)});

Use ? bindings instead of putting values into raw sql query.

If you're referring to the concept of accessors, then the simple goal is to hide the underlying storage from arbitrary manipulation. The most extreme mechanism for this is

function Foo(someValue) {
    this.getValue = function() { return someValue; }
    return this;
}

var myFoo = new Foo(5);
/* We can read someValue through getValue(), but there is no mechanism
 * to modify it -- hurrah, we have achieved encapsulation!
 */
myFoo.getValue();

If you're referring to the actual JS getter/setter feature, eg. defineGetter/defineSetter, or { get Foo() { /* code */ } }, then it's worth noting that in most modern engines subsequent usage of those properties will be much much slower than it would otherwise be. eg. compare performance of

var a = { getValue: function(){ return 5; }; }
for (var i = 0; i < 100000; i++)
    a.getValue();

vs.

var a = { get value(){ return 5; }; }
for (var i = 0; i < 100000; i++)
    a.value;

I can confirm this is a terminfo issue. This is what worked for me. SSH in to the remote machine and run

 sudo apt-get install ncurses-term

Boom. Problem solved.

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

A .sql file is a set of commands that can be executed against the SQL server.

Sometimes the .sql file will specify the database, other times you may need to specify this.

You should talk to your DBA or whoever is responsible for maintaining your databases. They will probably want to give the file a quick look. .sql files can do a lot of harm, even inadvertantly.

See the other answers if you want to plunge ahead.

Or use this:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
            android:scrollbars="vertical" 
            android:layout_height="wrap_content" 
            android:layout_width="fill_parent">

  <LinearLayout android:orientation="vertical"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent">

     <!-- Add your UI elements inside the inner most linear layout -->

  </LinearLayout>

The following code performs a HEAD request to check whether the website is available or not.

public static boolean isReachable(String targetUrl) throws IOException
{
    HttpURLConnection httpUrlConnection = (HttpURLConnection) new URL(
            targetUrl).openConnection();
    httpUrlConnection.setRequestMethod("HEAD");

    try
    {
        int responseCode = httpUrlConnection.getResponseCode();

        return responseCode == HttpURLConnection.HTTP_OK;
    } catch (UnknownHostException noInternetConnection)
    {
        return false;
    }
}

BigDecimal offers a string constructor. You'll need to strip all commas from the number, via via an regex or String filteredString=inString.replaceAll(",","").

You then simply call BigDecimal myBigD=new BigDecimal(filteredString);

You can also create a NumberFormat and call setParseBigDecimal(true). Then parse( will give you a BigDecimal without worrying about manually formatting.

Probably the simplest solution:

rome = n => {_x000D_
    b=0_x000D_
    s=''_x000D_
    for(a=5; n; b++,a^=7)_x000D_
        for(o=n%a, n=n/a^0;o--;)_x000D_
            s='IVXLCDM'[o>2?b+n-(n&=-2)+(o=1):b]+s_x000D_
    return s_x000D_
}_x000D_
_x000D_
r = [rome(892),rome(3999)];_x000D_
_x000D_
console.log(r);

I can't take credit though. This is vetalperko's solution on CodeSignal.

Install this nuget package from Microsoft System.Net.Http.Json. It contains extension methods.

Then add using System.Net.Http.Json

Now, you'll be able to see these methods:

So you can now do this:

await httpClient.GetFromJsonAsync<IList<WeatherForecast>>("weatherforecast");

I got this error when I was missing a closing bracket.

Simplified recreation:

const foo = () => {
  return (
    'bar'
  );
}; <== this bracket was missing

export default foo;

I used: "\n\r" - it only works in double quotes though.

var fvalue = "foo";
var svalue = "bar";
alert("My first value is: " + fvalue + "\n\rMy second value is: " + svalue);

Use Tag <p> always when starting with a new line so you don't need to use /n type syntax.

FLOAT stores floating point numbers with accuracy up to eight places and has four bytes while DOUBLE stores floating point numbers with accuracy upto 18 places and has eight bytes.

Your local port 443 / 8181 / 3820 is used.

If you are on linux/unix:

• use netstat -an and lsof -n to check who is using this port

If you are on windows

• use netstat -an and tcpview to check.

For me I switched a call for my collection view header where I was registering the nib to registering the class. That fixed it.

Run sudo visudo command then set -%sudo ALL=(ALL:ALL) to %sudo ALL=(ALL:ALL) NOPASSWD: ALL it will work.

The ParallelRegression package provides a setList( ) ordered set class that is more method-complete than the options based on the ActiveState recipe. It supports all methods available for lists and most if not all methods available for sets.

Create a custom authorization attribute based on AuthorizeAttribute and override OnAuthorization to perform the check how you want it done. Normally, AuthorizeAttribute will set the filter result to HttpUnauthorizedResult if the authorization check fails. You could have it set it to a ViewResult (of your Error view) instead.

EDIT: I have a couple of blog posts that go into more detail:

• http://farm-fresh-code.blogspot.com/2011/03/revisiting-custom-authorization-in.html
• http://farm-fresh-code.blogspot.com/2009/11/customizing-authorization-in-aspnet-mvc.html

Example:

    [AttributeUsage( AttributeTargets.Class | AttributeTargets.Method, Inherited = true, AllowMultiple = false )]
    public class MasterEventAuthorizationAttribute : AuthorizeAttribute
    {
        /// <summary>
        /// The name of the master page or view to use when rendering the view on authorization failure.  Default
        /// is null, indicating to use the master page of the specified view.
        /// </summary>
        public virtual string MasterName { get; set; }

        /// <summary>
        /// The name of the view to render on authorization failure.  Default is "Error".
        /// </summary>
        public virtual string ViewName { get; set; }

        public MasterEventAuthorizationAttribute()
            : base()
        {
            this.ViewName = "Error";
        }

        protected void CacheValidateHandler( HttpContext context, object data, ref HttpValidationStatus validationStatus )
        {
            validationStatus = OnCacheAuthorization( new HttpContextWrapper( context ) );
        }

        public override void OnAuthorization( AuthorizationContext filterContext )
        {
            if (filterContext == null)
            {
                throw new ArgumentNullException( "filterContext" );
            }

            if (AuthorizeCore( filterContext.HttpContext ))
            {
                SetCachePolicy( filterContext );
            }
            else if (!filterContext.HttpContext.User.Identity.IsAuthenticated)
            {
                // auth failed, redirect to login page
                filterContext.Result = new HttpUnauthorizedResult();
            }
            else if (filterContext.HttpContext.User.IsInRole( "SuperUser" ))
            {
                // is authenticated and is in the SuperUser role
                SetCachePolicy( filterContext );
            }
            else
            {
                ViewDataDictionary viewData = new ViewDataDictionary();
                viewData.Add( "Message", "You do not have sufficient privileges for this operation." );
                filterContext.Result = new ViewResult { MasterName = this.MasterName, ViewName = this.ViewName, ViewData = viewData };
            }

        }

        protected void SetCachePolicy( AuthorizationContext filterContext )
        {
            // ** IMPORTANT **
            // Since we're performing authorization at the action level, the authorization code runs
            // after the output caching module. In the worst case this could allow an authorized user
            // to cause the page to be cached, then an unauthorized user would later be served the
            // cached page. We work around this by telling proxies not to cache the sensitive page,
            // then we hook our custom authorization code into the caching mechanism so that we have
            // the final say on whether a page should be served from the cache.
            HttpCachePolicyBase cachePolicy = filterContext.HttpContext.Response.Cache;
            cachePolicy.SetProxyMaxAge( new TimeSpan( 0 ) );
            cachePolicy.AddValidationCallback( CacheValidateHandler, null /* data */);
        }

I understand that CASTing to FLOAT is not allowed in MySQL and will raise an error when you attempt to CAST(1 AS float) as stated at MySQL dev.

The workaround to this is a simple one. Just do

(1 + 0.0)

Then use ROUND to achieve a specific number of decimal places like

ROUND((1+0.0)/(2+0.0), 3)

The above SQL divides 1 by 2 and returns a float to 3 decimal places, as in it would be 0.500.

One can CAST to the following types: binary, char, date, datetime, decimal, json, nchar, signed, time, and unsigned.

http://dev.mysql.com/doc/refman/5.0/en/insert-select.html

For case1:

INSERT INTO TAB_STUDENT(name_student, id_teacher_fk)
SELECT 'Joe The Student', id_teacher
  FROM TAB_TEACHER
 WHERE name_teacher = 'Professor Jack'
 LIMIT 1

For case2 you just have to do 2 separate insert statements

When you are transitioning between Fragments, call addToBackStack() as part of your FragmentTransaction:

FragmentTransaction tx = fragmentManager.beginTransation();
tx.replace( R.id.fragment, new MyFragment() ).addToBackStack( "tag" ).commit();

If you require more detailed control (i.e. when some Fragments are visible, you want to suppress the back key) you can set an OnKeyListener on the parent view of your fragment:

//You need to add the following line for this solution to work; thanks skayred
fragment.getView().setFocusableInTouchMode(true);
fragment.getView().requestFocus();
fragment.getView().setOnKeyListener( new OnKeyListener()
{
    @Override
    public boolean onKey( View v, int keyCode, KeyEvent event )
    {
        if( keyCode == KeyEvent.KEYCODE_BACK )
        {
            return true;
        }
        return false;
    }
} );

I've been frustrated by this problem as well. Find/Replace can be helpful though, because if you don't put anything in the "replace" field it will replace with an -actual- NULL. So the steps would be something along the lines of:

1: Place some unique string in your formula in place of the NULL output (i like to use a password-like string)

2: Run your formula

3: Open Find/Replace, and fill in the unique string as the search value. Leave "replace with" blank

4: Replace All

Obviously, this has limitations. It only works when the context allows you to do a find/replace, so for more dynamic formulas this won't help much. But, I figured I'd put it up here anyway.

It seems most answers are assuming the arguments are filenames containing content to be cat'd to the stdin. Below everything is treated as just arguments. If STDIN is from the TTY, then it is ignored.

$ cat tstarg.rb

while a=(ARGV.shift or (!STDIN.tty? and STDIN.gets) )
  puts a
end

Either arguments or stdin can be empty or have data.

$ cat numbers 
1
2
3
4
5
$ ./tstarg.rb a b c < numbers
a
b
c
1
2
3
4
5

I believe you can use a case statement in a where clause, here is how I do it:

Select 
ProductID
OrderNo,
OrderType,
OrderLineNo
From Order_Detail
Where ProductID in (
Select Case when (@Varibale1 != '') 
then (Select ProductID from Product P Where .......)
Else (Select ProductID from Product)
End as ProductID
)

This method has worked for me time and again. try it!

The short answer is that not only is static useful, it is pretty well always going to be desired.

First, note that static and constexpr are completely independent of each other. static defines the object's lifetime during execution; constexpr specifies that the object should be available during compilation. Compilation and execution are disjoint and discontiguous, both in time and space. So once the program is compiled, constexpr is no longer relevant.

Every variable declared constexpr is implicitly const but const and static are almost orthogonal (except for the interaction with static const integers.)

The C++ object model (§1.9) requires that all objects other than bit-fields occupy at least one byte of memory and have addresses; furthermore all such objects observable in a program at a given moment must have distinct addresses (paragraph 6). This does not quite require the compiler to create a new array on the stack for every invocation of a function with a local non-static const array, because the compiler could take refuge in the as-if principle provided it can prove that no other such object can be observed.

That's not going to be easy to prove, unfortunately, unless the function is trivial (for example, it does not call any other function whose body is not visible within the translation unit) because arrays, more or less by definition, are addresses. So in most cases, the non-static const(expr) array will have to be recreated on the stack at every invocation, which defeats the point of being able to compute it at compile time.

On the other hand, a local static const object is shared by all observers, and furthermore may be initialized even if the function it is defined in is never called. So none of the above applies, and a compiler is free not only to generate only a single instance of it; it is free to generate a single instance of it in read-only storage.

So you should definitely use static constexpr in your example.

However, there is one case where you wouldn't want to use static constexpr. Unless a constexpr declared object is either ODR-used or declared static, the compiler is free to not include it at all. That's pretty useful, because it allows the use of compile-time temporary constexpr arrays without polluting the compiled program with unnecessary bytes. In that case, you would clearly not want to use static, since static is likely to force the object to exist at runtime.

The way I think of it is like this: A unit test establishes that the code does what you intended the code to do (e.g. you wanted to add parameter a and b, you in fact add them, and don't subtract them), functional tests test that all of the code works together to get a correct result, so that what you intended the code to do in fact gets the right result in the system.

I'll try and answer several different things, however my contribution may not cover all of your questions. Maybe several of us can take different chunks out of this. However, this info should be helpful for you. Here we go..

Opening A Seperate File:

ChDir "[Path here]"                          'get into the right folder here
Workbooks.Open Filename:= "[Path here]"      'include the filename in this path

'copy data into current workbook or whatever you want here

ActiveWindow.Close                          'closes out the file

Opening A File With Specified Date If It Exists:

I'm not sure how to search your directory to see if a file exists, but in my case I wouldn't bother to search for it, I'd just try to open it and put in some error checking so that if it doesn't exist then display this message or do xyz.

Some common error checking statements:

On Error Resume Next   'if error occurs continues on to the next line (ignores it)

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

Or (better option):

if one doesn't exist then bring up either a message box or dialogue box to say "the file does not exist, would you like to create a new one?

you would most likely want to use the GoTo ErrorHandler shown below to achieve this

On Error GoTo ErrorHandler:

ChDir "[Path here]"                         
Workbooks.Open Filename:= "[Path here]"      'try to open file here

ErrorHandler:
'Display error message or any code you want to run on error here

Much more info on Error handling here: http://www.cpearson.com/excel/errorhandling.htm

Also if you want to learn more or need to know more generally in VBA I would recommend Siddharth Rout's site, he has lots of tutorials and example code here: http://www.siddharthrout.com/vb-dot-net-and-excel/

Hope this helps!

Example on how to ensure error code doesn't run EVERYtime:

if you debug through the code without the Exit Sub BEFORE the error handler you'll soon realize the error handler will be run everytime regarldess of if there is an error or not. The link below the code example shows a previous answer to this question.

  Sub Macro

    On Error GoTo ErrorHandler:

    ChDir "[Path here]"                         
    Workbooks.Open Filename:= "[Path here]"      'try to open file here

    Exit Sub      'Code will exit BEFORE ErrorHandler if everything goes smoothly
                  'Otherwise, on error, ErrorHandler will be run

    ErrorHandler:
    'Display error message or any code you want to run on error here

  End Sub

Also, look at this other question in you need more reference to how this works: goto block not working VBA

Function I wrote for a requirement similar to this with pure javascript string manipulation

"http://www.google.lk/?Name=John&Age=20&Gender=Male"

function queryize(sampleurl){
    var tokens = url.split('?')[1].split('&');
    var result = {};

    for(var i=0; i<tokens.length; i++){
        result[tokens[i].split('=')[0]] = tokens[i].split('=')[1];
    }

    return result;
}

Usage:

queryize(window.location.href)['Name'] //returns John
queryize(window.location.href)['Age'] //returns 20
queryize(window.location.href)['Gender'] //returns Male

If you're okay with loosing array keys, you may flatten a multi-dimensional array using a recursive closure as a callback that utilizes array_values(), making sure that this callback is a parameter for array_walk(), as follows.

<?php  

$array = [1,2,3,[5,6,7]];
$nu_array = null;
$callback = function ( $item ) use(&$callback, &$nu_array) {
    if (!is_array($item)) {
    $nu_array[] = $item;
    }
    else
    if ( is_array( $item ) ) {
     foreach( array_values($item) as $v) {
         if ( !(is_array($v))) {
             $nu_array[] = $v;
         }
         else
         { 
             $callback( $v );
         continue;
         }    
     }
    }
};

array_walk($array, $callback);
print_r($nu_array);

The one drawback of the preceding example is that it involves writing far more code than the following solution which uses array_walk_recursive() along with a simplified callback:

<?php  

$array = [1,2,3,[5,6,7]];

$nu_array = [];
array_walk_recursive($array, function ( $item ) use(&$nu_array )
                     {
                         $nu_array[] = $item;
                     }
);
print_r($nu_array);

See live code

This example seems preferable to the previous one, hiding the details about how values are extracted from a multidimensional array. Surely, iteration occurs, but whether it entails recursion or control structure(s), you'll only know from perusing array.c. Since functional programming focuses on input and output rather than the minutiae of obtaining a result, surely one can remain unconcerned about how behind-the-scenes iteration occurs, that is until a perspective employer poses such a question.

The error is coming as your query is getting formed as

SELECT * FROM Employ where number = parseInt(val);

I dont know which DB you are using but no DB will understand parseInt.

What you can do is use a variable say temp and store the value of parseInt(val) in temp variable and make the query as

SELECT * FROM Employ where number = temp;

I'd consider using a nullable types.

DateTime? myDate instead of DateTime myDate.

Sorry, but it might even be more complicated, involving pbkdf2, or even a variation of it. Listen to the WWDC 2010 session #209, which mainly talks about the security measures in iOS 4, but also mentions briefly the separate encryption of backups and how they're related.

You can be pretty sure that without knowing the password, there's no way you can decrypt it, even by brute force.

Let's just assume you want to try to enable people who KNOW the password to get to the data of their backups.

I fear there's no way around looking at the actual code in iTunes in order to figure out which algos are employed.

Back in the Newton days, I had to decrypt data from a program and was able to call its decryption function directly (knowing the password, of course) without the need to even undersand its algorithm. It's not that easy anymore, unfortunately.

I'm sure there are skilled people around who could reverse engineer that iTunes code - you just have to get them interested.

In theory, Apple's algos should be designed in a way that makes the data still safe (i.e. practically unbreakable by brute force methods) to any attacker knowing the exact encryption method. And in WWDC session 209 they went pretty deep into details about what they do to accomplish this. Maybe you can actually get answers directly from Apple's security team if you tell them your good intentions. After all, even they should know that security by obfuscation is not really efficient. Try their security mailing list. Even if they do not repond, maybe someone else silently on the list will respond with some help.

Good luck!

you can make that using transform and transform origins.

Combining various transfroms gives similar result. I hope you find it helpful. :) See these examples for simpler transforms. this has left point :

what transform: 0% 50%; does is it sets the origin to vertical middle and horizontal left of the element. so the perspective is not visible at the left part of the image, so it looks flat. Perspective effect is there at the right part, so it looks slanted.

I'm sure this question should have a more general answer with some reusable code that works with cookies as key-value pairs.

This snippet is taken from MDN and probably is trustable. This is UTF-safe object for work with cookies:

var docCookies = {
  getItem: function (sKey) {
    return decodeURIComponent(document.cookie.replace(new RegExp("(?:(?:^|.*;)\\s*" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=\\s*([^;]*).*$)|^.*$"), "$1")) || null;
  },
  setItem: function (sKey, sValue, vEnd, sPath, sDomain, bSecure) {
    if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/i.test(sKey)) { return false; }
    var sExpires = "";
    if (vEnd) {
      switch (vEnd.constructor) {
        case Number:
          sExpires = vEnd === Infinity ? "; expires=Fri, 31 Dec 9999 23:59:59 GMT" : "; max-age=" + vEnd;
          break;
        case String:
          sExpires = "; expires=" + vEnd;
          break;
        case Date:
          sExpires = "; expires=" + vEnd.toUTCString();
          break;
      }
    }
    document.cookie = encodeURIComponent(sKey) + "=" + encodeURIComponent(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");
    return true;
  },
  removeItem: function (sKey, sPath, sDomain) {
    if (!sKey || !this.hasItem(sKey)) { return false; }
    document.cookie = encodeURIComponent(sKey) + "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + ( sDomain ? "; domain=" + sDomain : "") + ( sPath ? "; path=" + sPath : "");
    return true;
  },
  hasItem: function (sKey) {
    return (new RegExp("(?:^|;\\s*)" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=")).test(document.cookie);
  },
  keys: /* optional method: you can safely remove it! */ function () {
    var aKeys = document.cookie.replace(/((?:^|\s*;)[^\=]+)(?=;|$)|^\s*|\s*(?:\=[^;]*)?(?:\1|$)/g, "").split(/\s*(?:\=[^;]*)?;\s*/);
    for (var nIdx = 0; nIdx < aKeys.length; nIdx++) { aKeys[nIdx] = decodeURIComponent(aKeys[nIdx]); }
    return aKeys;
  }
};

Mozilla has some tests to prove this works in all cases.

There is an alternative snippet here:

$.ajax({
  type: "POST",
  contentType: "application/json; charset=utf-8",
  url: "ChnagePassword.aspx/AutocompleteSuggestions",
  data: "{'searchstring':'" + request.term + "','st':'Arb'}",
  dataType: "json",
  success: function (data) {
     response($.map(data.d, function (item) {
         return { value: item }
     }))
  },
  error: function (result) {
      alert("Error");
  }
});

You need to be careful though, You need to setup the EDMX file exactly as it was before deleting it (if you choose the delete/regenerate route), otherwise, you'll have a naming mismatch between your code and the EF generated model (especialy for pluralization and singularization)

Hope this will prevent you some headaches =)

git pull is nothing but git fetch followed by git merge. So what you can do is

git fetch remote example_branch

git merge <commit_hash>

You can think of a mysql database as a schema/user in Oracle. If you have the privileges, you can query the DBA_USERS view to see the list of schema.

The correct answer to this question has been changed by the publication of RFC 8314. As a result, port 465 and 587 are both valid ports for a mail submission agent (MSA). Port 465 requires negotiation of TLS/SSL at connection setup and port 587 uses STARTTLS if one chooses to negotiate TLS. The IANA registry was updated to allow legitimate use of port 465 for this purpose. For mail relay, only port 25 is used so STARTTLS is the only way to do TLS with mail relay. It's helpful to think of mail relay and mail submission as two very different services (with many behavior differences like requiring auth, different timeouts, different message modification rules, etc.) that happen to use a similar wire protocol.

All the above is not necessary.

The issue I was having was I was using the -g when I was running NPM. I couldn't work out how I wasn't getting a 'npm_module' folder created in my project.

The solution is to run 'NPM init' This creates a 'package.json' and the 'npm_module' folder where all subsequent modules will be loaded into. When running npm DO NOT use -g use -s to update your 'package.json' file.

Here is a good video explaining

An old post but here is how I handled it. Using newms87's method:

if($action == "redemption")
{
    if($redemptionId != "")
    {
        $results = json_decode($rewards->redeemPoints($redemptionId));

        if($results->success == true)
        {
            $redirectLocation = $GLOBALS['BASE_URL'] . 'rewards.phtml?a=redemptionComplete';
            // put results in session and redirect back to same page passing an action paraameter
            $_SESSION['post_data'] = json_encode($results);
            header("Location:" . $redirectLocation);
            exit();
        }
    }
}
elseif($action == "redemptionComplete")
{
    // if data is in session pull it and unset it.
    if(isset($_SESSION['post_data']))
    {
        $results = json_decode($_SESSION['post_data']);
        unset($_SESSION['post_data']);
    }
    // if you got here, you completed the redemption and reloaded the confirmation page. So redirect back to rewards.phtml page.
    else
    {
        $redirectLocation = $GLOBALS['BASE_URL'] . 'rewards.phtml';
        header("Location:" . $redirectLocation);
    }
}

This may be too simplistic of an answer (I am still new here), but what I have done in the past to remedy this situation is figured out the percentage of the screen I would like the image to take up. For example, there is one webpage I am working on where the logo must take up 30% of the screen size to look best. I played around and finally tried this code and it has worked for me thus far:

img {
width:30%;
height:auto;
}

That being said, this will change all of your images to be 30% of the screen size at all times. To get around this issue, simply make this a class and apply it to the image that you desire to be at 30% directly. Here is an example of the code I wrote to accomplish this on the aforementioned site:

the CSS portion:

.logo {
position:absolute;
right:25%;
top:0px;
width:30%;
height:auto;
}

the HTML portion:

<img src="logo_001_002.png" class="logo">

Alternatively, you could place ever image you hope to automatically resize into a div of its own and use the class tag option on each div (creating now class tags whenever needed), but I feel like that would cause a lot of extra work eventually. But, if the site calls for it: the site calls for it.

Hopefully this helps. Have a great day!

the best way to set corporate proxy with ntlm authentication is to use cntlm:

http://cntlm.sourceforge.net/

Install and configure in C:\Program Files\Cntlm\cntlm.ini By default cntlm, listens to 127.0.0.1:3128

In android device set a new APN with proxy host 10.0.2.2 and port 3128 10.0.2.2 is a special alias to your host loopback interface (127.0.0.1 on your development machine)
