There are a couple of things you could look at. Based on your question, it looks like the function owner is different from the table owner.

1) Grants via a role : In order to create stored procedures and functions on another user's objects, you need direct access to the objects (instead of access through a role).

2)

By default, stored procedures and SQL methods execute with the privileges of their owner, not their current user.

If you created a table in Schema A and the function in Schema B, you should take a look at Oracle's Invoker/Definer Rights concepts to understand what might be causing the issue.

It happened in IE 11 for me. And I was calling the jquery .load function. So I did it the old fashion way and put something in the url to disable cacheing.

$("#divToReplaceHtml").load('@Url.Action("Action", "Controller")/' + @Model.ID + "?nocache=" + new Date().getTime());

Eclipse is not that hard to learn (I use both Eclipse and NetBeans, and I switch back and forth pretty effortlessly). If you're going to be learning Android development from the start, I can recommend Hello, Android, which I just finished. It shows you exactly how to use all the features of Eclipse that are useful for developing Android apps. There's also a brief section on getting set up to develop from the command line and from other IDEs.

If you want to limit memory for jvm (not the heap size ) ulimit -v

To get an idea of the difference between jvm and heap memory , take a look at this excellent article http://blogs.vmware.com/apps/2011/06/taking-a-closer-look-at-sizing-the-java-process.html

You can pass all your optional arguments in an object as the first argument. The second argument is your callback. Now you can accept as many arguments as you want in your first argument object, and make it optional like so:

function my_func(op, cb) {
    var options = (typeof arguments[0] !== "function")? arguments[0] : {},
        callback = (typeof arguments[0] !== "function")? arguments[1] : arguments[0];

    console.log(options);
    console.log(callback);
}

If you call it without passing the options argument, it will default to an empty object:

my_func(function () {});
=> options: {}
=> callback: function() {}

If you call it with the options argument you get all your params:

my_func({param1: 'param1', param2: 'param2'}, function () {});
=> options: {param1: "param1", param2: "param2"}
=> callback: function() {}

This could obviously be tweaked to work with more arguments than two, but it get's more confusing. If you can just use an object as your first argument then you can pass an unlimited amount of arguments using that object. If you absolutely need more optional arguments (e.g. my_func(arg1, arg2, arg3, ..., arg10, fn)), then I would suggest using a library like ArgueJS. I have not personally used it, but it looks promising.

Try to change the buildToolsVersion for 23.0.2 in Gradle Script build.gradle (Module App)

and set buildToolsVersion "23.0.2"

then rebuild

var flags = inputstring.replace(/.*\/([gimy]*)$/, '$1');
var pattern = inputstring.replace(new RegExp('^/(.*?)/'+flags+'$'), '$1');
var regex = new RegExp(pattern, flags);

or

var match = inputstring.match(new RegExp('^/(.*?)/([gimy]*)$'));
// sanity check here
var regex = new RegExp(match[1], match[2]);

This will show the 10th line of myfile.txt:

get-content myfile.txt | select -first 1 -skip 9

both -first and -skip are optional parameters, and -context, or -last may be useful in similar situations.

The Bootstrap datepicker is able to set date-range. But it is not available in the initial release/Master Branch. Check the branch as 'range' there (or just see at https://github.com/eternicode/bootstrap-datepicker), you can do it simply with startDate and endDate.

Example:

$('#datepicker').datepicker({
    startDate: '-2m',
    endDate: '+2d'
});

You can use this custom library (written using Promise) to make a remote call.

function $http(apiConfig) {
    return new Promise(function (resolve, reject) {
        var client = new XMLHttpRequest();
        client.open(apiConfig.method, apiConfig.url);
        client.send();
        client.onload = function () {
            if (this.status >= 200 && this.status < 300) {
                // Performs the function "resolve" when this.status is equal to 2xx.
                // Your logic here.
                resolve(this.response);
            }
            else {
                // Performs the function "reject" when this.status is different than 2xx.
                reject(this.statusText);
            }
        };
        client.onerror = function () {
            reject(this.statusText);
        };
    });
}

Simple usage example:

$http({
    method: 'get',
    url: 'google.com'
}).then(function(response) {
    console.log(response);
}, function(error) {
    console.log(error)
});

finally I got the solution:

Only put this line

@RequestMapping(value = "/YOUR_URL_Name",method = RequestMethod.POST,produces = "application/json; charset=utf-8")

this will definitely help.

Maybe I didn't understand your problem right, because of the simplicity of your example. To my understanding, you have a series of instructions stored in character vectors, and those instructions are very close to being properly formatted, except that you'd like to cast the right member to numeric.

If my understanding is right, I would like to propose a slightly different approach, that does not rely on splitting your original string, but directly evaluates your instruction (with a little improvement).

original_string <- "variable_name=\"10\"" # Your original instruction, but with an actual numeric on the right, stored as character.
library(magrittr) # Or library(tidyverse), but it seems a bit overkilled if the point is just to import pipe-stream operator
eval(parse(text=paste(eval(original_string), "%>% as.numeric")))
print(variable_name)
#[1] 10

Basically, what we are doing is that we 'improve' your instruction variable_name="10" so that it becomes variable_name="10" %>% as.numeric, which is an equivalent of variable_name=as.numeric("10") with magrittr pipe-stream syntax. Then we evaluate this expression within current environment.

Hope that helps someone who'd wander around here 8 years later ;-)

Your original problem was wrong pattern symbol "h" which stands for the clock hour (range 1-12). In this case, the am-pm-information is missing. Better, use the pattern symbol "H" instead (hour of day in range 0-23). So the pattern should rather have been like:

uuuu-MM-dd'T'HH:mm:ss.SSSX (best pattern also suitable for strict mode)

You might have pressed 0 (also used for insert, shortcut INS) key, which is on the right side of your right scroll button. To solve the problem, just press it again or double click on 'overwrite'.

Simply replace image/jpeg with application/octet-stream. The client would not recognise the URL as an inline-able resource, and prompt a download dialog.

A simple JavaScript solution would be:

//var img = reference to image
var url = img.src.replace(/^data:image\/[^;]+/, 'data:application/octet-stream');
window.open(url);
// Or perhaps: location.href = url;
// Or even setting the location of an <iframe> element, 

Another method is to use a blob: URI:

var img = document.images[0];
img.onclick = function() {
    // atob to base64_decode the data-URI
    var image_data = atob(img.src.split(',')[1]);
    // Use typed arrays to convert the binary data to a Blob
    var arraybuffer = new ArrayBuffer(image_data.length);
    var view = new Uint8Array(arraybuffer);
    for (var i=0; i<image_data.length; i++) {
        view[i] = image_data.charCodeAt(i) & 0xff;
    }
    try {
        // This is the recommended method:
        var blob = new Blob([arraybuffer], {type: 'application/octet-stream'});
    } catch (e) {
        // The BlobBuilder API has been deprecated in favour of Blob, but older
        // browsers don't know about the Blob constructor
        // IE10 also supports BlobBuilder, but since the `Blob` constructor
        //  also works, there's no need to add `MSBlobBuilder`.
        var bb = new (window.WebKitBlobBuilder || window.MozBlobBuilder);
        bb.append(arraybuffer);
        var blob = bb.getBlob('application/octet-stream'); // <-- Here's the Blob
    }

    // Use the URL object to create a temporary URL
    var url = (window.webkitURL || window.URL).createObjectURL(blob);
    location.href = url; // <-- Download!
};

sed -i 's/[[:blank:]]\{1,\}$//' YourFile

[:blank:] is for space, tab mainly and {1,} to exclude 'no space at the end' of the substitution process (no big significant impact if line are short and file are small)

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

This one is much more human readable.

Some answers are partially wrong, and some facts in them are partially wrong as well.

Answer your question: Yes! You can.

In Typescript

class A {
    private a1;
    private a2;


}

Generates the following code in Javascript:

var A = /** @class */ (function () {
    function A() {
    }
    return A;
}());

as @Erik_Cupal said, you could just do:

let a = new A();
let array = return Object.getOwnPropertyNames(a);

But this is incomplete. What happens if your class has a custom constructor? You need to do a trick with Typescript because it will not compile. You need to assign as any:

let className:any = A;
let a = new className();// the members will have value undefined

A general solution will be:

class A {
    private a1;
    private a2;
    constructor(a1:number, a2:string){
        this.a1 = a1;
        this.a2 = a2;
    }
}

class Describer{

   describeClass( typeOfClass:any){
       let a = new typeOfClass();
       let array = Object.getOwnPropertyNames(a);
       return array;//you can apply any filter here
   }
}

For better understanding this will reference depending on the context.

Set the CSS position: relative; on the box. This causes all absolute positions of objects inside to be relative to the corners of that box. Then set the following CSS on the "Bet 5 days ago" line:

position: absolute;
bottom: 0;
right: 0;

If you need to space the text farther away from the edge, you could change 0 to 2px or similar.

Other option is not to use crontab -e at all. Instead I used:

(crontab -l && echo "1 1  * * *  /path/to/my/script.sh") | crontab -

Notice that whatever you print before | crontab - will replace the entire crontab file, so use crontab -l && echo "<your new schedule>" to get the previous content and the new schedule.

The value attribute on submit-type <input> elements controls the text displayed.

<input type="submit" class="like" value="Like" />

When you declare

var a=[];

you are declaring a empty array.

But when you are declaring

var a={};

you are declaring a Object .

Although Array is also Object in Javascript but it is numeric key paired values. Which have all the functionality of object but Added some few method of Array like Push,Splice,Length and so on.

So if you want Some values where you need to use numeric keys use Array. else use object. you can Create object like:

var a={name:"abc",age:"14"}; 

And can access values like

console.log(a.name);

conda should have given us a simple tool like cond env rename <old> <new> but it hasn't. Simply renaming the directory, as in this previous answer, of course, breaks the hardcoded hashbangs(#!). Hence, we need to go one more level deeper to achieve what we want.

conda env list
# conda environments:
#
base                  *  /home/tgowda/miniconda3
junkdetect               /home/tgowda/miniconda3/envs/junkdetect
rtg                      /home/tgowda/miniconda3/envs/rtg

Here I am trying to rename rtg --> unsup (please bear with those names, this is my real use case)

$ cd /home/tgowda/miniconda3/envs 
$ OLD=rtg
$ NEW=unsup
$ mv $OLD $NEW   # rename dir

$ conda env list
# conda environments:
#
base                  *  /home/tgowda/miniconda3
junkdetect               /home/tgowda/miniconda3/envs/junkdetect
unsup                    /home/tgowda/miniconda3/envs/unsup


$ conda activate $NEW
$ which python
  /home/tgowda/miniconda3/envs/unsup/bin/python

the previous answer reported upto this, but wait, we are not done yet! the pending task is, $NEW/bin dir has a bunch of executable scripts with hashbangs (#!) pointing to the $OLD env paths.

See jupyter, for example:

$ which jupyter
/home/tgowda/miniconda3/envs/unsup/bin/jupyter

$ head -1 $(which jupyter) # its hashbang is still looking at old
#!/home/tgowda/miniconda3/envs/rtg/bin/python

So, we can easily fix it with a sed

$ sed  -i.bak "s:envs/$OLD/bin:envs/$NEW/bin:" $NEW/bin/*  
# `-i.bak` created backups, to be safe

$ head -1 $(which jupyter) # check if updated
#!/home/tgowda/miniconda3/envs/unsup/bin/python
$ jupyter --version # check if it works
jupyter core     : 4.6.3
jupyter-notebook : 6.0.3

$ rm $NEW/bin/*.bak  # remove backups

Now we are done

I think it should be trivial to write a portable script to do all those and bind it to conda env rename old new.

I tested this on ubuntu. For whatever unforseen reasons, if things break and you wish to revert the above changes:

$ mv $NEW  $OLD
$ sed  -i.bak "s:envs/$NEW/bin:envs/$OLD/bin:" $OLD/bin/*

<?php
$myArray = new array('1', '2');
$seralizedArray = serialize($myArray);
?>

your error is because of you use class and when use class we need to bind the functions with This in order to work well. anyway there are a lot of tutorial why we should "this" and what is "this" do in javascript.

if you correct your submit button it should be work:

<button type="button" onClick={this.onSubmit.bind(this)} className="btn">Save</button>

and also if you want to show value of that input in console you should use var title = this.title.value;

 where c.FullName.Contains("string")

I use MDI quite a lot, I like it much more (where it can be used) than multiple floating forms.

But to get the best from it you need to get to grips with your own events. It makes life so much easier for you.

A skeletal example.

Have your own interupt types,

//Clock, Stock and Accoubts represent the actual forms in
//the MDI application. When I have multiple copies of a form
//I also give them an ID, at the time they are created, then
//include that ID in the Args class.
public enum InteruptSource
{
    IS_CLOCK = 0, IS_STOCKS, IS_ACCOUNTS
}
//This particular event type is time based,
//but you can add others to it, such as document
//based.
public enum EVInterupts
{
    CI_NEWDAY = 0, CI_NEWMONTH, CI_NEWYEAR, CI_PAYDAY, CI_STOCKPAYOUT, 
   CI_STOCKIN, DO_NEWEMAIL, DO_SAVETOARCHIVE
}

Then your own Args type

public class ControlArgs
{
    //MDI form source
    public InteruptSource source { get; set; }
    //Interrupt type
    public EVInterupts clockInt { get; set; }
    //in this case only a date is needed
    //but normally I include optional data (as if a C UNION type)
    //the form that responds to the event decides if
    //the data is for it.
    public DateTime date { get; set; }
    //CI_STOCKIN
    public StockClass inStock { get; set; }

}

Then use the delegate within your namespace, but outside of a class

namespace MyApplication
{
public delegate void StoreHandler(object sender, ControlArgs e);
  public partial class Form1 : Form
{
  //your main form
}

Now either manually or using the GUI, have the MDIparent respond to the events of the child forms.

But with your owr Args, you can reduce this to a single function. and you can have provision to interupt the interupts, good for debugging, but can be usefull in other ways too.

Just have al of your mdiparent event codes point to the one function,

        calendar.Friday += new StoreHandler(MyEvents);
        calendar.Saturday += new StoreHandler(MyEvents);
        calendar.Sunday += new StoreHandler(MyEvents);
        calendar.PayDay += new StoreHandler(MyEvents);
        calendar.NewYear += new StoreHandler(MyEvents);

A simple switch mechanism is usually enough to pass events on to appropriate forms.

Any suggestions/examples? I followed SwingWorker... The code was very messy and I don't like this approach.

Instead of get(), which waits for completion, use process() and setProgress() to show intermediate results, as suggested in this simple example or this related example.

I have always had to write some PL/SQL for this or I just concatenate a ',' to the field and copy into an editor and remove the CR from the list giving me the single line.

That is,

select country_name||', ' country from countries

A little bit long winded both ways.

If you look at Ask Tom you will see loads of possible solutions but they all revert to type declarations and/or PL/SQL

As explained in the accepted answer, https://stackoverflow.com/a/18665488/4038790, you need to check via a server.

Because there's no reliable way to check this in the browser, I suggest you build yourself a quick server endpoint that you can use to check if any url is loadable via iframe. Once your server is up and running, just send a AJAX request to it to check any url by providing the url in the query string as url (or whatever your server desires). Here's the server code in NodeJs:

const express = require('express')_x000D_
const app = express()_x000D_
_x000D_
app.get('/checkCanLoadIframeUrl', (req, res) => {_x000D_
  const request = require('request')_x000D_
  const Q = require('q')_x000D_
_x000D_
  return Q.Promise((resolve) => {_x000D_
    const url = decodeURIComponent(req.query.url)_x000D_
_x000D_
    const deafultTimeout = setTimeout(() => {_x000D_
      // Default to false if no response after 10 seconds_x000D_
      resolve(false)_x000D_
    }, 10000)_x000D_
_x000D_
    request({_x000D_
        url,_x000D_
        jar: true /** Maintain cookies through redirects */_x000D_
      })_x000D_
      .on('response', (remoteRes) => {_x000D_
        const opts = (remoteRes.headers['x-frame-options'] || '').toLowerCase()_x000D_
        resolve(!opts || (opts !== 'deny' && opts !== 'sameorigin'))_x000D_
        clearTimeout(deafultTimeout)_x000D_
      })_x000D_
      .on('error', function() {_x000D_
        resolve(false)_x000D_
        clearTimeout(deafultTimeout)_x000D_
      })_x000D_
  }).then((result) => {_x000D_
    return res.status(200).json(!!result)_x000D_

})_x000D_
_x000D_

Set Keyword: In VBA, the Set keyword is necessary to distinguish between assignment of an object and assignment of the default property of the object. Since default properties are not supported in Visual Basic .NET, the Set keyword is not needed and is no longer supported.

Solution : SpreadsheetApp.getActiveSheet().getRange('F2').setValue('hello')

Explanation :

Setting value in a cell in spreadsheet to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in sheet which is open currently and to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet name known)

SpreadsheetApp.openById(SHEET_ID).getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet position known)

SpreadsheetApp.openById(SHEET_ID).getSheets()[POSITION].getRange(RANGE).setValue(VALUE);

These are constants, you must define them yourself

SHEET_ID

SHEET_NAME

POSITION

VALUE

RANGE

By script attached to a sheet I mean that script is residing in the script editor of that sheet. Not attached means not residing in the script editor of that sheet. It can be in any other place.

Typings can be configured with the ~/.typingsrc config file. (~ means your home directory)

After finding this issue on github: https://github.com/typings/typings/issues/120, I was able to hack around this issue by creating ~/.typingsrc and setting this configuration:

{
  "proxy": "http://<server>:<port>",
  "rejectUnauthorized": false
}

It also seemed to work without the proxy setting, so maybe it was able to pick that up from the environment somewhere.

This is not a true solution, but was enough for typings to ignore the corporate firewall issues so that I could continue working. I'm sure there is a better solution out there.

Use the CSS white-space property instead of opening yourself up to XSS vulnerabilities!

<span style="white-space: pre-line">@Model.CommentText</span>

Try the below code

HttpRequest req = System.Web.HttpContext.Current.Request
string browserName = req.Browser.Browser;

Having some experience of this, you can indeed use C++ code for your "core" code, but you have to use objective-C for anything iPhone specific.

Don't try to force Objective-C to act like C++. At first it will seem to you this is possible, but the resulting code really won't work well with Cocoa, and you will get very confused as to what is going on. Take the time to learn properly, without any C++ around, how to build GUIs and iPhone applications, then link in your C++ base.

Not sure exactly what your problem is, but try the following:

1. Do the font files exist?
2. Do you need quotes around the URLs?
3. Are you using a CSS3-enabled browser?

Check here for examples, if they don't work for you then you have another problem

Edit:

You have a bunch of repeated declarations in your source, does this work?

@font-face { font-family: Gotham; src: url('../fonts/gothammedium.eot'); }

a { font-family:Gotham,Verdana,Arial; }

When you add a foreign key constraint to a table using ALTER TABLE, remember to create the required indexes first.

1. Create index
2. Alter table

2. Add '{{the path where your MinGW was installed}}/bin' to current user environment variable - "Path" in Windows, then reboot eclipse, and finally recompile.

3. Add '{{the path where your MinGW was installed}}/bin' to Windows environment variable - "Path", then reboot eclipse, and finally recompile.

4. Copy the file "libstdc++-6.dll" to the path where the *.exe file is running, then rerun. (this is not a good way)

Note: the file "libstdc++-6.dll" is in the folder '{{the path where your MinGW was installed}}/bin'

In swift do like this:
First in your ViewController implement this UITextFieldDelegate For eg.

class MyViewController: UIViewController, UITextFieldDelegate {
....
}

Now add a delegate to a TextField in which you want to dismiss the keyboard when return is tapped either in viewDidLoad method like below or where you are initializing it. For eg.

override func viewDidLoad() {

    super.viewDidLoad()   
    myTextField.delegate = self
}

Now add this method.

func textFieldShouldReturn(textField: UITextField) -> Bool {

    textField.resignFirstResponder()
    return true
}

I got this error, while using it on my rocketchat to communicate with my gitlab via enterprise proxy,

Because, was using the https://:8080 but actually, it worked for http://:8080

I'm not sure I completely understand the question, but a list of keyboard short cuts can be found here - Hope this helps!

In addition to @Cinn's answer, you can define a class like this

class MyAppBar extends AppBar with PreferredSizeWidget {
  @override
  get preferredSize => Size.fromHeight(50);

  MyAppBar({Key key, Widget title}) : super(
    key: key,
    title: title,
    // maybe other AppBar properties
  );
}

or this way

class MyAppBar extends PreferredSize {
  MyAppBar({Key key, Widget title}) : super(
    key: key,
    preferredSize: Size.fromHeight(50),
    child: AppBar(
      title: title,
      // maybe other AppBar properties
    ),
  );
}

and then use it instead of standard one

List is an interface so you can't instanciate it. Use any of its implementatons instead e.g.

List<Object> object = new List<Object>();

About List : you can use any object as a generic param for it instance:

List<?> list = new ArrayList<String>();

or

List<?> list = new ArrayList<Integer>();

While using List<Object> this declaration is invalid because it will be type missmatch.

I don't know this for sure, but I think this is supposed to be handled by the browser based on the user's date/time settings. Try setting your computer to display dates in that format.

Thanks to Alex Mckay I had a resolve for dynamic setting a props:

  for(let prop in filter)
      (state.filter as Record<string, any>)[prop] = filter[prop];

Use : Tools in Menu -> Options -> Environment -> Fonts and Colors

Additionally, for our Android friends (API Level 8):

import android.util.Base64

...

Base64.encodeToString(bytes, Base64.DEFAULT);

I wrote a simple logger, which can log query with inserted parameters. Installation:

composer require cmyker/doctrine-sql-logger:dev-master

Usage:

$connection = $this->getEntityManager()->getConnection(); 
$logger = new \Cmyker\DoctrineSqlLogger\Logger($connection);
$connection->getConfiguration()->setSQLLogger($logger);
//some query here
echo $logger->lastQuery;

 System.Diagnostics.ProcessStartInfo psi =
   new System.Diagnostics.ProcessStartInfo(@"program_to_call.exe");
 psi.RedirectStandardOutput = true;
 psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
 psi.UseShellExecute = false;
 System.Diagnostics.Process proc = System.Diagnostics.Process.Start(psi); ////
 System.IO.StreamReader myOutput = proc.StandardOutput;
 proc.WaitForExit(2000);
 if (proc.HasExited)
  {
      string output = myOutput.ReadToEnd();
 }

Using generators

import os
def get_files(search_path):
     for (dirpath, _, filenames) in os.walk(search_path):
         for filename in filenames:
             yield os.path.join(dirpath, filename)
list_files = get_files('.')
for filename in list_files:
    print(filename)

<script type="text/javascript">
var app = angular.module('sampleapp', [])
app.controller('samplecontrol', function ($scope) {
   var today = new Date();
   console.log($scope.cdate);
   var date = today.getDate();
   var month = today.getMonth();
   var year = today.getFullYear();
   var current_date = date+'/'+month+'/'+year;
   console.log(current_date);
});
</script>

If you'd decide for a solution acting "in place" you could take a look at this one:

>>> d = [ { 'a':'1' , 'b':'2' , 'c':'3' }, { 'd':'4' , 'e':'5' , 'f':'6' } ]
>>> [dt.update({k: int(v)}) for dt in d for k, v in dt.iteritems()]
[None, None, None, None, None, None]
>>> d
[{'a': 1, 'c': 3, 'b': 2}, {'e': 5, 'd': 4, 'f': 6}]

Btw, key order is not preserved because that's the way standard dictionaries work, ie without the concept of order.

It is the SQL extension called analytics. The "over" in the select statement tells oracle that the function is a analytical function, not a group by function. The advantage to using analytics is that you can collect sums, counts, and a lot more with just one pass through of the data instead of looping through the data with sub selects or worse, PL/SQL.

It does look confusing at first but this will be second nature quickly. No one explains it better then Tom Kyte. So the link above is great.

Of course, reading the documentation is a must.

Nobody mentioned using reversed:

f=open(file,"r")
r=reversed(f.readlines())
last_line_of_file = r.next()

A quick and dirty way is to find out the class of the footer and hide it using jQuery or CSS:

$(".dataTables_info").hide();

This is referred to as screen scraping, wikipedia has this article on the more specific web scraping. It can be a major challenge because there's some ugly, mess-up, broken-if-not-for-browser-cleverness HTML out there, so good luck.

DateTime.FromFileTime should do the trick:

PS C:\> [datetime]::FromFileTime(129948127853609000)

Monday, October 15, 2012 3:13:05 PM

Then depending on how you want to format it, check out standard and custom datetime format strings.

PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('d MMMM')
15 October
PS C:\> [datetime]::FromFileTime(129948127853609000).ToString('g')
10/15/2012 3:13 PM

If you want to integrate this into your one-liner, change your select statement to this:

... | Select Name, manager, @{N='LastLogon'; E={[DateTime]::FromFileTime($_.LastLogon)}} | ...

Upload (multiple) binary files

Node.js

Things become complicated when you want to post files via multipart/form-data, especially multiple binary files. Below is a working example:

const FormData = require('form-data')
const fs = require('fs')
const path = require('path')

const formData = new FormData()
formData.append('files[]', JSON.stringify({ to: [{ phoneNumber: process.env.RINGCENTRAL_RECEIVER }] }), 'test.json')
formData.append('files[]', fs.createReadStream(path.join(__dirname, 'test.png')), 'test.png')
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData, {
  headers: formData.getHeaders()
})

• Instead of headers: {'Content-Type': 'multipart/form-data' } I prefer headers: formData.getHeaders()
• I use async and await above, you can change them to plain Promise statements if you don't like them
• In order to add your own headers, you just headers: { ...yourHeaders, ...formData.getHeaders() }

Newly added content below:

Browser

Browser's FormData is different from the NPM package 'form-data'. The following code works for me in browser:

HTML:

<input type="file" id="image" accept="image/png"/>

JavaScript:

const formData = new FormData()

// add a non-binary file
formData.append('files[]', new Blob(['{"hello": "world"}'], { type: 'application/json' }), 'request.json')

// add a binary file
const element = document.getElementById('image')
const file = element.files[0]
formData.append('files[]', file, file.name)
await rc.post('/restapi/v1.0/account/~/extension/~/fax', formData)

try this:
sudo pip install -i https://testpypi.python.org/pypi psycopg2==2.7b2
.. this is especially helpful if you're running into egg error

on aws ec2 instances if you run into gcc error; try this
1. sudo yum install gcc python-setuptools python-devel postgresql-devel
2. sudo su -
3. sudo pip install psycopg2

Apparently, your project is targeting Windows Phone 7.0. Unfortunately the constructors that accept IEnumerable<T> or List<T> are not available in WP 7.0, only the parameterless constructor. The other constructors are available in Silverlight 4 and above and WP 7.1 and above, just not in WP 7.0.

I guess your only option is to take your list and add the items into a new instance of an ObservableCollection individually as there are no readily available methods to add them in bulk. Though that's not to stop you from putting this into an extension or static method yourself.

var list = new List<SomeType> { /* ... */ };
var oc = new ObservableCollection<SomeType>();
foreach (var item in list)
    oc.Add(item);

But don't do this if you don't have to, if you're targeting framework that provides the overloads, then use them.

You can use the finish command.

finish: Continue running until just after function in the selected stack frame returns. Print the returned value (if any). This command can be abbreviated as fin.

(See 5.2 Continuing and Stepping.)

Great then. Let's create a simple function that takes an array and prints our an ordered listview/list inside a div tag.

Step 1: Let's say you have an div with "contentSectionID" id.<div id="contentSectionID"></div>

Step 2: We then create our javascript function that returns a list component and takes in an array:

function createList(spacecrafts){

var listView=document.createElement('ol');

for(var i=0;i<spacecrafts.length;i++)
{
    var listViewItem=document.createElement('li');
    listViewItem.appendChild(document.createTextNode(spacecrafts[i]));
    listView.appendChild(listViewItem);
}

return listView;
}

Step 3: Finally we select our div and create a listview in it:

document.getElementById("contentSectionID").appendChild(createList(myArr));

The normal way to install Python libraries is with pip. Your way of installing it for Python 3.2 works because it's the system Python, and that's the way to install things for system-provided Pythons on Debian-based systems.

If your Python 3.3 is system-provided, you should probably use a similar command. Otherwise you should probably use pip.

I took my Python 3.3 installation, created a virtualenv and run pip install in it, and that seems to have worked as expected:

$ virtualenv-3.3 testenv
$ cd testenv
$ bin/pip install numpy
blablabl

$ bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux

The following code works for me fine.

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("message/rfc822");
intent.putExtra(Intent.EXTRA_SUBJECT, subject);
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"abc@gmailcom"});
Intent mailer = Intent.createChooser(intent, null);
startActivity(mailer);

Long version:

private bool booleanMethod () {
    if (your_condition) {
        return true;
    } else {
        return false;
    }
}

But since you are using the outcome of your condition as the result of the method you can shorten it to

private bool booleanMethod () {
    return your_condition;
}

set "_os=64"
if "%PROCESSOR_ARCHITECTURE%"=="x86" (if not defined PROCESSOR_ARCHITEW6432 set "_os=32")

and http://ss64.com/nt/syntax-64bit.html

I see it's missing the obvious answer:

function array_map_assoc(){
    if(func_num_args() < 2) throw new \BadFuncionCallException('Missing parameters');

    $args = func_get_args();
    $callback = $args[0];

    if(!is_callable($callback)) throw new \InvalidArgumentException('First parameter musst be callable');

    $arrays = array_slice($args, 1);

    array_walk($arrays, function(&$a){
        $a = (array)$a;
        reset($a);
    });

    $results = array();
    $max_length = max(array_map('count', $arrays));

    $arrays = array_map(function($pole) use ($max_length){
        return array_pad($pole, $max_length, null);
    }, $arrays);

    for($i=0; $i < $max_length; $i++){
        $elements = array();
        foreach($arrays as &$v){
            $elements[] = each($v);
        }
        unset($v);

        $out = call_user_func_array($callback, $elements);

        if($out === null) continue;

        $val = isset($out[1]) ? $out[1] : null;

        if(isset($out[0])){
            $results[$out[0]] = $val;
        }else{
            $results[] = $val;
        }
    }

    return $results;
}

Works exactly like array_map. Almost.

Actually, it's not pure map as you know it from other languages. Php is very weird, so it requires some very weird user functions, for we don't want to unbreak our precisely broken worse is better approach.

Really, it's not actually map at all. Yet, it's still very useful.

• First obvious difference from array_map, is that the callback takes outputs of each() from every input array instead of value alone. You can still iterate through more arrays at once.

• Second difference is the way the key is handled after it's returned from callback; the return value from callback function should be array('new_key', 'new_value'). Keys can and will be changed, same keys can even cause previous value being overwritten, if same key was returned. This is not common map behavior, yet it allows you to rewrite keys.

• Third weird thing is, if you omit key in return value (either by array(1 => 'value') or array(null, 'value')), new key is going to be assigned, as if $array[] = $value was used. That isn't map's common behavior either, yet it comes handy sometimes, I guess.

• Fourth weird thing is, if callback function doesn't return a value, or returns null, the whole set of current keys and values is omitted from the output, it's simply skipped. This feature is totally unmappy, yet it would make this function excellent stunt double for array_filter_assoc, if there was such function.

• If you omit second element (1 => ...) (the value part) in callback's return, null is used instead of real value.

• Any other elements except those with keys 0 and 1 in callback's return are ignored.

• And finally, if lambda returns any value except of null or array, it's treated as if both key and value were omitted, so:

  1. new key for element is assigned
  2. null is used as it's value

WARNING:
Bear in mind, that this last feature is just a residue of previous features and it is probably completely useless. Relying on this feature is highly discouraged, as this feature is going to be randomly deprecated and changed unexpectedly in future releases.

NOTE:
Unlike in array_map, all non-array parameters passed to array_map_assoc, with the exception of first callback parameter, are silently casted to arrays.

EXAMPLES:
// TODO: examples, anyone?

List.clear would remove the elements without reducing the capacity of the list.

groovy:000> mylist = [1,2,3,4,5,6,7,8,9,10,11,12]
===> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12]
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist.clear()
===> null
groovy:000> mylist.elementData.length
===> 12
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@19d6af
groovy:000> mylist = new ArrayList();
===> []
groovy:000> mylist.elementData
===> [Ljava.lang.Object;@2bfdff
groovy:000> mylist.elementData.length
===> 10

Here mylist got cleared, the references to the elements held by it got nulled out, but it keeps the same backing array. Then mylist was reinitialized and got a new backing array, the old one got GCed. So one way holds onto memory, the other one throws out its memory and gets reallocated from scratch (with the default capacity). Which is better depends on whether you want to reduce garbage-collection churn or minimize the current amount of unused memory. Whether the list sticks around long enough to be moved out of Eden might be a factor in deciding which is faster (because that might make garbage-collecting it more expensive).

Manually:

int strlen(string s)
{
    int len = 0;

    while (s[len])
        len++;

    return len;
}

Add the below mentioned attribute on the property in your model class.

Attribute = [DatabaseGenerated(DatabaseGeneratedOption.Computed)]
Reference = System.ComponentModel.DataAnnotations.Schema

Initially I forgot to add this attribute. So in my database the constraint was created like

ALTER TABLE [dbo].[TableName] ADD DEFAULT (getdate()) FOR [ColumnName]

and I added this attribute and updated my db then it got changed into

ALTER TABLE [dbo].[TableName] ADD CONSTRAINT [DF_dbo.TableName_ColumnName] DEFAULT (getdate()) FOR [ColumnName]

For Me adding few below line in WebApi.config works as after updating the new nuget package did not works out

var setting = config.Formatters.JsonFormatter.SerializerSettings;
setting.ContractResolver = new CamelCasePropertyNamesContractResolver();
setting.Formatting = Formatting.Indented;

Don't forget to add namespace:

using Newtonsoft.Json.Serialization; 
using Newtonsoft.Json;

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted

Try:

String.prototype.lpad = function(padString, length) {
    var str = this;
    while (str.length < length)
        str = padString + str;
    return str;
}

Now test:

var str = "5";
alert(str.lpad("0", 4)); //result "0005"
var str = "10"; // note this is string type
alert(str.lpad("0", 4)); //result "0010"

DEMO

In ECMAScript 2017 , we have new method padStart and padEnd which has below syntax.

"string".padStart(targetLength [,padString]):

So now we can use

const str = "5";
str.padStart(4, "0"); // "0005"

Please check which user account you use to execute our task. It may happen that you run your task with different user then your default user, and this user requires some extra privileges. Also it may happen that the task is executed but you cant see any effect because the batch file waits for some user response so please check task manager if you see your process running. Once it happen that I schedule a batch with svn update of some web page and the process hangs because svn asked for accepting server certificate.

Intro

As of the time of writing, the original answer is now 8 years old. Still I feel like there isn't yet a proper solution to the original question.

Bootstrap has gone a long way since then and is now at 4.5.2. This answer addresses this very version.

The problem with all other solutions so far

The issue with all the other answers is, that while they hook into show.bs.dropdown / hide.bs.dropdown, the follow-up events shown.bs.dropdown / hidden.bs.dropdown are either fired too early (animation still ongoing) or they don't fire at all because they were suppressed (e.preventDefault()).

A clean solution

Since the implementation of show() and hide() in Bootstraps Dropdown class share some similarities, I've grouped them together in toggleDropdownWithAnimation() when mimicing the original behaviour and added little QoL helper functions to showDropdownWithAnimation() and hideDropdownWithAnimation().
toggleDropdownWithAnimation() creates a shown.bs.dropdown / hidden.bs.dropdown event the same way Bootstrap does it. This event is then fired after the animation completed - just like you would expect.

/**
 * Toggle visibility of a dropdown with slideDown / slideUp animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {boolean} show Show (true) or hide (false) the dropdown menu.
 * @param {number} duration Duration of the animation in milliseconds
 */
function toggleDropdownWithAnimation($containerElement, show, duration = 300): void {
    // get the element that triggered the initial event
    const $toggleElement = $containerElement.find('.dropdown-toggle');
    // get the associated menu
    const $dropdownMenu = $containerElement.find('.dropdown-menu');
    // build jquery event for when the element has been completely shown
    const eventArgs = {relatedTarget: $toggleElement};
    const eventType = show ? 'shown' : 'hidden';
    const eventName = `${eventType}.bs.dropdown`;
    const jQueryEvent = $.Event(eventName, eventArgs);

    if (show) {
        // mimic bootstraps element manipulation
        $containerElement.addClass('show');
        $dropdownMenu.addClass('show');
        $toggleElement.attr('aria-expanded', 'true');
        // put focus on initial trigger element
        $toggleElement.trigger('focus');
        // start intended animation
        $dropdownMenu
            .stop() // stop any ongoing animation
            .hide() // hide element to fix initial state of element for slide down animation
            .slideDown(duration, () => {
            // fire 'shown' event
            $($toggleElement).trigger(jQueryEvent);
        });
    }
    else {
        // mimic bootstraps element manipulation
        $containerElement.removeClass('show');
        $dropdownMenu.removeClass('show');
        $toggleElement.attr('aria-expanded', 'false');
        // start intended animation
        $dropdownMenu
            .stop() // stop any ongoing animation
            .show() // show element to fix initial state of element for slide up animation
            .slideUp(duration, () => {

            // fire 'hidden' event
            $($toggleElement).trigger(jQueryEvent);
        });
    }
}

/**
 * Show a dropdown with slideDown animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {number} duration Duration of the animation in milliseconds
 */
function showDropdownWithAnimation($containerElement, duration = 300) {
    toggleDropdownWithAnimation($containerElement, true, duration);
}

/**
 * Hide a dropdown with a slideUp animation.
 * @param {JQuery} $containerElement The outer dropdown container. This is the element with the .dropdown class.
 * @param {number} duration Duration of the animation in milliseconds
 */
function hideDropdownWithAnimation($containerElement, duration = 300) {
    toggleDropdownWithAnimation($containerElement, false, duration);
}

Bind Event Listeners

Now that we have written proper callbacks for showing / hiding a dropdown with an animation, let's actually bind these to the correct events.

A common mistake I've seen a lot in other answers is binding event listeners to elements directly. While this works fine for DOM elements present at the time the event listener is registered, it does not bind to elements added later on.

That's why you are generally better off binding directly to the document:

$(function () {

    /* Hook into the show event of a bootstrap dropdown */
    $(document).on('show.bs.dropdown', '.dropdown', function (e) {
        // prevent bootstrap from executing their event listener
        e.preventDefault();
        
        showDropdownWithAnimation($(this));
    });

    /* Hook into the hide event of a bootstrap dropdown */
    $(document).on('hide.bs.dropdown', '.dropdown', function (e) {
        // prevent bootstrap from executing their event listener
        e.preventDefault();
          
        hideDropdownWithAnimation($(this));
    });

});

On Linux, the symlink /proc/<pid>/exe has the path of the executable. Use the command readlink -f /proc/<pid>/exe to get the value.

On AIX, this file does not exist. You could compare cksum <actual path to binary> and cksum /proc/<pid>/object/a.out.

You can install eclipse theme plugin then select default. Please visit here: http://eclipsecolorthemes.org/?view=plugin

You have to specify 0 (meaning false) or 1 (meaning true) as the default. Here is an example:

create table mytable (
     mybool boolean not null default 0
);

FYI: boolean is an alias for tinyint(1).

Here is the proof:

mysql> create table mytable (
    ->          mybool boolean not null default 0
    ->     );
Query OK, 0 rows affected (0.35 sec)

mysql> insert into mytable () values ();
Query OK, 1 row affected (0.00 sec)

mysql> select * from mytable;
+--------+
| mybool |
+--------+
|      0 |
+--------+
1 row in set (0.00 sec)

FYI: My test was done on the following version of MySQL:

mysql> select version();
+----------------+
| version()      |

You don't need javascript for doing so. Just delete the onClick and write the php Admin.php file like this:

<!-- HTML STARTS-->
<?php
//If all the required fields are filled
if (!empty($GET_['fullname'])&&!empty($GET_['email'])&&!empty($GET_['name']))
{
function addNewContact()
    {
    $new = '{';
    $new .= '"fullname":"' . $_GET['fullname'] . '",';
    $new .= '"email":"' . $_GET['email'] . '",';
    $new .= '"phone":"' . $_GET['phone'] . '",';
    $new .= '}';
    return $new;
    }

function saveContact()
    {
    $datafile = fopen ("data/data.json", "a+");
    if(!$datafile){
        echo "<script>alert('Data not existed!')</script>";
        } 
    else{
        $contact_list = $contact_list . addNewContact();
        file_put_contents("data/data.json", $contact_list);
        }
    fclose($datafile);
    }

// Call the function saveContact()
saveContact();
echo "Thank you for joining us";
}
else //If the form is not submited or not all the required fields are filled

{ ?>

<form>
    <fieldset>
        <legend>Add New Contact</legend>
        <input type="text" name="fullname" placeholder="First name and last name" required /> <br />
        <input type="email" name="email" placeholder="[email protected]" required /> <br />
        <input type="text" name="phone" placeholder="Personal phone number: mobile, home phone etc." required /> <br />
        <input type="submit" name="submit" class="button" value="Add Contact"/>
        <input type="button" name="cancel" class="button" value="Reset" />
    </fieldset>
</form>
<?php }
?>
<!-- HTML ENDS -->

Thought I don't like the PHP bit. Do you REALLY want to create a file for contacts? It'd be MUCH better to use a mysql database. Also, adding some breaks to that file would be nice too...

Other thought, IE doesn't support placeholder.

One line code:

System.out.println(new Gson().fromJson(jsonLine,JsonObject.class).getAsJsonObject().get("data").getAsJsonObject().get("translations").getAsJsonArray().get(0).getAsJsonObject().get("translatedText").getAsString());

Following command worked out for me nicely. It gives you the OS name and version.

lsb_release -a

It is possible, but unfortunately mostly in WebKit-based browsers to the extent we, as developers, require. Here is the example of CSS styling gathered from Chrome options panel via built-in developer tools inspector, improved to match currently supported CSS properties in most modern browsers:

select {
    -webkit-appearance: button;
    -moz-appearance: button;
    -webkit-user-select: none;
    -moz-user-select: none;
    -webkit-padding-end: 20px;
    -moz-padding-end: 20px;
    -webkit-padding-start: 2px;
    -moz-padding-start: 2px;
    background-color: #F07575; /* Fallback color if gradients are not supported */
    background-image: url(../images/select-arrow.png), -webkit-linear-gradient(top, #E5E5E5, #F4F4F4); /* For Chrome and Safari */
    background-image: url(../images/select-arrow.png), -moz-linear-gradient(top, #E5E5E5, #F4F4F4); /* For old Firefox (3.6 to 15) */
    background-image: url(../images/select-arrow.png), -ms-linear-gradient(top, #E5E5E5, #F4F4F4); /* For pre-releases of Internet Explorer  10*/
    background-image: url(../images/select-arrow.png), -o-linear-gradient(top, #E5E5E5, #F4F4F4); /* For old Opera (11.1 to 12.0) */
    background-image: url(../images/select-arrow.png), linear-gradient(to bottom, #E5E5E5, #F4F4F4); /* Standard syntax; must be last */
    background-position: center right;
    background-repeat: no-repeat;
    border: 1px solid #AAA;
    border-radius: 2px;
    box-shadow: 0px 1px 3px rgba(0, 0, 0, 0.1);
    color: #555;
    font-size: inherit;
    margin: 0;
    overflow: hidden;
    padding-top: 2px;
    padding-bottom: 2px;
    text-overflow: ellipsis;
    white-space: nowrap;
}

When you run this code on any page within a WebKit-based browser it should change the appearance of the select box, remove standard OS-arrow and add a PNG-arrow, put some spacing before and after the label, almost anything you want.

The most important part is appearance property, which changes how the element behaves.

It works perfectly in almost all WebKit-based browser, including mobile ones, though Gecko doesn't support appearance as well as WebKit, it seems.

Thanks loelsonk, i did so

const [dataAction, setDataAction] = useState({name: '', description: ''});_x000D_
_x000D_
    const _handleChangeName = (data) => {_x000D_
        if(data.name)_x000D_
            setDataAction( prevState  => ({ ...prevState,   name : data.name }));_x000D_
        if(data.description)_x000D_
            setDataAction( prevState  => ({ ...prevState,   description : data.description }));_x000D_
    };_x000D_
    _x000D_
    ....return (_x000D_
    _x000D_
          <input onChange={(event) => _handleChangeName({name: event.target.value})}/>_x000D_
          <input onChange={(event) => _handleChangeName({description: event.target.value})}/>_x000D_
    )

In my case ASP.NET State Service was stopped. Changing the Startup type to Automatic and starting the service manually for the first time solved the issue.

You can use the parseInt() function to convert the string to a number, e.g:

parseInt($('#elem').css('top'));

Update: (as suggested by Ben): You should give the radix too:

parseInt($('#elem').css('top'), 10);

Forces it to be parsed as a decimal number, otherwise strings beginning with '0' might be parsed as an octal number (might depend on the browser used).

create an empty modal box on the current page and below is the ajax call you can see how to fetch the content in result from another html page.

 $.ajax({url: "registration.html", success: function(result){
            //alert("success"+result);
              $("#contentBody").html(result);
            $("#myModal").modal('show'); 

        }});

once the call is done you will get the content of the page by the result to then you can insert the code in you modal's content id using.

You can call controller and get the page content and you can show that in your modal.

below is the example of Bootstrap 3 modal in that we are loading content from registration.html page...

You can use node.js http module to do that. You could check the documentation at Node.js HTTP.

You would need to pass the query string as well to the other HTTP Server. You should have that in ServerRequest.url.

Once you have those info, you could pass in the backend HTTP Server and port in the options that you will provide in the http.request()

The ls command has a parameter -t to sort by time. You can then grab the first (newest) with head -1.

ls -t b2* | head -1

But beware: Why you shouldn't parse the output of ls

My personal opinion: parsing ls is only dangerous when the filenames can contain funny characters like spaces or newlines. If you can guarantee that the filenames will not contain funny characters then parsing ls is quite safe.

If you are developing a script which is meant to be run by many people on many systems in many different situations then I very much do recommend to not parse ls.

Here is how to do it "right": How can I find the latest (newest, earliest, oldest) file in a directory?

unset -v latest
for file in "$dir"/*; do
  [[ $file -nt $latest ]] && latest=$file
done

You can call the method getBoundingClientRect() on a reference to the element. Then you can examine the top, left, right and/or bottom properties...

var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;

If using jQuery, you can use the more succinct code...

var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

You can use an echo with a pipe to avoid prompts or confirmation.

echo "This is the body" | mail -s "This is the subject" [email protected]

Here is the alternative solution to check whether a particular string contains some predefined string. It uses IndexOf Function:

'this is your string
Dim strMyString As String = "aaSomethingbb"

'if your string contains these strings
Dim TargetString1 As String = "Something"
Dim TargetString2 As String = "Something2"

If strMyString.IndexOf(TargetString1) <> -1 Or strMyString.IndexOf(TargetString2) <> -1 Then

End If

NOTE: This solution has been tested with Visual Studio 2010.

<link rel="SHORTCUT ICON" href="favicon.ico" type="image/x-icon" />
<link rel="ICON" href="favicon.ico" type="image/ico" />

Hopefully this is self explanatory enough. Use the comments in the code to help understand what is happening. Pass a single cell to this function. The value of that cell will be the base file name. If the cell contains "AwesomeData" then we will try and create a file in the current users desktop called AwesomeData.pdf. If that already exists then try AwesomeData2.pdf and so on. In your code you could just replace the lines filename = Application..... with filename = GetFileName(Range("A1"))

Function GetFileName(rngNamedCell As Range) As String
    Dim strSaveDirectory As String: strSaveDirectory = ""
    Dim strFileName As String: strFileName = ""
    Dim strTestPath As String: strTestPath = ""
    Dim strFileBaseName As String: strFileBaseName = ""
    Dim strFilePath As String: strFilePath = ""
    Dim intFileCounterIndex As Integer: intFileCounterIndex = 1

    ' Get the users desktop directory.
    strSaveDirectory = Environ("USERPROFILE") & "\Desktop\"
    Debug.Print "Saving to: " & strSaveDirectory

    ' Base file name
    strFileBaseName = Trim(rngNamedCell.Value)
    Debug.Print "File Name will contain: " & strFileBaseName

    ' Loop until we find a free file number
    Do
        If intFileCounterIndex > 1 Then
            ' Build test path base on current counter exists.
            strTestPath = strSaveDirectory & strFileBaseName & Trim(Str(intFileCounterIndex)) & ".pdf"
        Else
            ' Build test path base just on base name to see if it exists.
            strTestPath = strSaveDirectory & strFileBaseName & ".pdf"
        End If

        If (Dir(strTestPath) = "") Then
            ' This file path does not currently exist. Use that.
            strFileName = strTestPath
        Else
            ' Increase the counter as we have not found a free file yet.
            intFileCounterIndex = intFileCounterIndex + 1
        End If

    Loop Until strFileName <> ""

    ' Found useable filename
    Debug.Print "Free file name: " & strFileName
    GetFileName = strFileName

End Function

The debug lines will help you figure out what is happening if you need to step through the code. Remove them as you see fit. I went a little crazy with the variables but it was to make this as clear as possible.

In Action

My cell O1 contained the string "FileName" without the quotes. Used this sub to call my function and it saved a file.

Sub Testing()
    Dim filename As String: filename = GetFileName(Range("o1"))

    ActiveWorkbook.Worksheets("Sheet1").Range("A1:N24").ExportAsFixedFormat Type:=xlTypePDF, _
                                              filename:=filename, _
                                              Quality:=xlQualityStandard, _
                                              IncludeDocProperties:=True, _
                                              IgnorePrintAreas:=False, _
                                              OpenAfterPublish:=False
End Sub

Where is your code located in reference to everything else? Perhaps you need to make a module if you have not already and move your existing code into there.

Do use NULL. It is just #defined as 0 anyway and it is very useful to semantically distinguish it from the integer 0.

There are problems with using 0 (and hence NULL). For example:

void f(int);
void f(void*);

f(0); // Ambiguous. Calls f(int).

The next version of C++ (C++0x) includes nullptr to fix this.

f(nullptr); // Calls f(void*).

Starting with xdebug 3 you can use the following command line :

php -r "xdebug_info();"

And it will display useful information about your xdebug installation.

I was having this problem on a Windows 7 (64 bit) after a power outage. The SQLEXPRESS service was not started even though is status was set to 'Automatic' and the mahine had been rebooted several times. Had to start the service manually.

Add this to your project-level build.gradle file:

repositories {
    maven {
        url "https://maven.google.com"
    }
}

It worked for me

Keep in mind while using HTML5 pushstate if a user copies or bookmarks a deep link and visits it again, then that will be a direct server hit which will 404 so you need to be ready for it and even a pushstate js library won't help you. The easiest solution is to add a rewrite rule to your Nginx or Apache server like so:

Apache (in your vhost if you're using one):

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /
    RewriteRule ^index\.html$ - [L]
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteRule . /index.html [L]
 </IfModule>

Nginx

rewrite ^(.+)$ /index.html last;

If you are using sagemath cloud version, you can simply go to the left corner,
select File --> Download as --> Pdf via LaTeX (.pdf)
Check the screenshot if you want.

Screenshot Convert ipynb to pdf

If it dosn't work for any reason, you can try another way.
select File --> Print Preview and then on the preview
right click --> Print and then select save as pdf.

Non of the above solutions worked for me. I used the code that exists in the documentation of NodeMailer. It looks like this:

let transporter = nodemailer.createTransport({
    host: 'smtp.gmail.com',
    port: 465,
    secure: true,
    auth: {
        type: 'OAuth2',
        user: '[email protected]',
        serviceClient: '113600000000000000000',
        privateKey: '-----BEGIN PRIVATE KEY-----\nMIIEvgIBADANBg...',
        accessToken: 'ya29.Xx_XX0xxxxx-xX0X0XxXXxXxXXXxX0x',
        expires: 1484314697598
    }
}); 

I have used below code in my custom library
call that from my controller like below,

function __construct() {<br />
   &nbsp;&nbsp;&nbsp; parent::__construct();<br />
   &nbsp;&nbsp;&nbsp;   $this->load->library('CommonMethods');<br />
}<br />

$config['max_height'] = 150;<br />
$config['encrypt_name'] = TRUE;<br />
$config['overwrite'] = FALSE;<br />

// upload multiplefiles<br />
$fileUploadResponse = $this->commonmethods->do_upload_multiple_files('profile_picture', $config);

    $files = $_FILES;
    $cpt = count($_FILES[$fieldName]['name']);
    for($i=0; $i<$cpt; $i++)
    {           
        $_FILES[$fieldName]['name']= $files[$fieldName]['name'][$i];
        $_FILES[$fieldName]['type']= $files[$fieldName]['type'][$i];

To provide another approach similar to the answer by @IvanCollantes. It works by additionally filtering the required checkboxes by name. I also simplified the code a bit and checks for a default checked checkbox.

jQuery(function($) {_x000D_
  var requiredCheckboxes = $(':checkbox[required]');_x000D_
  requiredCheckboxes.on('change', function(e) {_x000D_
    var checkboxGroup = requiredCheckboxes.filter('[name="' + $(this).attr('name') + '"]');_x000D_
    var isChecked = checkboxGroup.is(':checked');_x000D_
    checkboxGroup.prop('required', !isChecked);_x000D_
  });_x000D_
  requiredCheckboxes.trigger('change');_x000D_
});

Go to Xcode -> preference -> fonts and color, then pick the presentation one. The font will be enlarged automatically.

It may be "better" to not use attach at all. On the plus side, you can save some typing if you use attach. Let's say your dataset is called mydata and you have variables called v1, v2, and v3. If you don't attach mydata, then you will type mean(mydata$v1) to get the mean of v1. If you do attach mydata, then you will type mean(v1) to get the mean of v1. But, if you don't detach the mydata dataset (every time), you'll get the message about the objects being masked going forward.

Solution 1 (assuming you want to attach):

1. Use detach every time.
2. See Dan Tarr's response if you already have the data attached (and it may be in the global environment several times). Then, in the future, use detach every time.

Solution 2

Don't use attach. Instead, include the dataset name every time you refer to a variable. The form is mydata$v1 (name of data set, dollar sign, name of variable).

As for me, I used solution 1 a lot in the past, but I've moved to solution 2. It's a bit more typing in the beginning, but if you are going to use the code multiple times, it just seems cleaner.

pd.concat accepts a dictionary. With this in mind, it is possible to improve upon the currently accepted answer in terms of simplicity and performance by use a dictionary comprehension to build a dictionary mapping keys to sub-frames.

pd.concat({k: pd.DataFrame(v).T for k, v in user_dict.items()}, axis=0)

Or,

pd.concat({
        k: pd.DataFrame.from_dict(v, 'index') for k, v in user_dict.items()
    }, 
    axis=0)

              att_1     att_2
12 Category 1     1  whatever
   Category 2    23   another
15 Category 1    10       foo
   Category 2    30       bar

df['y'] will set a column

since you want to set a row, use .loc

Note that .ix is equivalent here, yours failed because you tried to assign a dictionary to each element of the row y probably not what you want; converting to a Series tells pandas that you want to align the input (for example you then don't have to to specify all of the elements)

As already mentioned, usually the comparison is done through subtraction.

At the hardware level there are special digital circuits for doing the calculations, like adders.

In the context of Ektron, this issue is resolved by installing the "IIS6 Metabase compatibility" feature in Windows:

Check 'Windows features' or 'Role Services' for IIS6 Metabase compatibility, add if missing:

Ref: https://portal.ektron.com/KB/1088/

The following will do.

unsigned int x = 1;
printf ("%d", (int) (((char *)&x)[0]));

And setting &x to char * will enable you to access the individual bytes of the integer, and the ordering of bytes will depend on the endianness of the system.

There is a lot of ways to achieve this. In regards to the way you are asking, with a hidden form element.

create this form element inside your form:

<input type="hidden" name="total" value="">

So your form like this:

<form id="sampleForm" name="sampleForm" method="post" action="phpscript.php">
<input type="hidden" name="total" id="total" value="">
<a href="#" onclick="setValue();">Click to submit</a>
</form>

Then your javascript something like this:

<script>
function setValue(){
    document.sampleForm.total.value = 100;
    document.forms["sampleForm"].submit();
}
</script>

For the best practice - use style="display:"

it will work every where..

One issue with your ContentLoader is that internally it operates sequentially. A better pattern is to parallelize the work and then sychronize at the end, so we get

public class PageViewModel : IHandle<SomeMessage>
{
   ...

   public async void Handle(SomeMessage message)
   {
      ShowLoadingAnimation();

      // makes UI very laggy, but still not dead
      await this.contentLoader.LoadContentAsync(); 

      HideLoadingAnimation();   
   }
}

public class ContentLoader 
{
    public async Task LoadContentAsync()
    {
        var tasks = new List<Task>();
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoIoBoundWorkAsync());
        tasks.Add(DoCpuBoundWorkAsync());
        tasks.Add(DoSomeOtherWorkAsync());

        await Task.WhenAll(tasks).ConfigureAwait(false);
    }
}

Obviously, this doesn't work if any of the tasks require data from other earlier tasks, but should give you better overall throughput for most scenarios.

You've got a couple of issues here.

Firstly, you're defining your code within an anonymous function. This construct:

(function() {
  ...
)();

does two things. It defines an anonymous function and calls it. There are scope reasons to do this but I'm not sure it's what you actually want.

You're passing in a code block to setTimeout(). The problem is that update() is not within scope when executed like that. It however if you pass in a function pointer instead so this works:

(function() {
  $(document).ready(function() {update();});

  function update() { 
    $("#board").append(".");
    setTimeout(update, 1000);     }
  }
)();

because the function pointer update is within scope of that block.

But like I said, there is no need for the anonymous function so you can rewrite it like this:

$(document).ready(function() {update();});

function update() { 
  $("#board").append(".");
  setTimeout(update, 1000);     }
}

or

$(document).ready(function() {update();});

function update() { 
  $("#board").append(".");
  setTimeout('update()', 1000);     }
}

and both of these work. The second works because the update() within the code block is within scope now.

I also prefer the $(function() { ... } shortened block form and rather than calling setTimeout() within update() you can just use setInterval() instead:

$(function() {
  setInterval(update, 1000);
});

function update() {
  $("#board").append(".");
}

Hope that clears that up.

I've created a directive for AngularJS - heavely inspired by GeekyMonkey's answer but without the jQuery dependency.

Demo: http://plnkr.co/edit/8tPCZIjvO3VSApSeTtYr?p=preview

Markup

<div class="fittext" max-font-size="50" text="Your text goes here..."></div>

Directive

app.directive('fittext', function() {

  return {
    scope: {
      minFontSize: '@',
      maxFontSize: '@',
      text: '='
    },
    restrict: 'C',
    transclude: true,
    template: '<div ng-transclude class="textContainer" ng-bind="text"></div>',
    controller: function($scope, $element, $attrs) {
      var fontSize = $scope.maxFontSize || 50;
      var minFontSize = $scope.minFontSize || 8;

      // text container
      var textContainer = $element[0].querySelector('.textContainer');

      angular.element(textContainer).css('word-wrap', 'break-word');

      // max dimensions for text container
      var maxHeight = $element[0].offsetHeight;
      var maxWidth = $element[0].offsetWidth;

      var textContainerHeight;
      var textContainerWidth;      

      var resizeText = function(){
        do {
          // set new font size and determine resulting dimensions
          textContainer.style.fontSize = fontSize + 'px';
          textContainerHeight = textContainer.offsetHeight;
          textContainerWidth = textContainer.offsetWidth;

          // shrink font size
          var ratioHeight = Math.floor(textContainerHeight / maxHeight);
          var ratioWidth = Math.floor(textContainerWidth / maxWidth);
          var shrinkFactor = ratioHeight > ratioWidth ? ratioHeight : ratioWidth;
          fontSize -= shrinkFactor;

        } while ((textContainerHeight > maxHeight || textContainerWidth > maxWidth) && fontSize > minFontSize);        
      };

      // watch for changes to text
      $scope.$watch('text', function(newText, oldText){
        if(newText === undefined) return;

        // text was deleted
        if(oldText !== undefined && newText.length < oldText.length){
          fontSize = $scope.maxFontSize;
        }
        resizeText();
      });
    }
  };
});

When people talk about HTML5 applications they're most likely talking about writing just a simple web page or embedding a web page into their app (which will essentially provide the user interface). For the later there are different frameworks available, e.g. PhoneGap. These are used to provide more than the default browser features (e.g. multi touch) as well as allowing the app to run seamingly "standalone" and without the browser's navigation bars etc.

As Baptiste said, you need to specify the data argument at the geom level. Either

#df1 is the default dataset for all geoms
(plot1 <- ggplot(df1, aes(v, p)) + 
    geom_point() +
    geom_step(data = df2)
)

or

#No default; data explicitly specified for each geom
(plot2 <- ggplot(NULL, aes(v, p)) + 
      geom_point(data = df1) +
      geom_step(data = df2)
)

$('#myDiv').children().each( (index, element) => {
    console.log(index);     // children's index
    console.log(element);   // children's element
 });

This iterates through all the children and their element with index value can be accessed separately using element and index respectively.

I have done that the more simple way, not as clean as it should be but it was a quick hack

$htmlContent = file_get_contents('pageURL');

// read all image tags into an array
preg_match_all('/<img[^>]+>/i',$htmlContent, $imgTags); 

for ($i = 0; $i < count($imgTags[0]); $i++) {
  // get the source string
  preg_match('/src="([^"]+)/i',$imgTags[0][$i], $imgage);

  // remove opening 'src=' tag, can`t get the regex right
  $origImageSrc[] = str_ireplace( 'src="', '',  $imgage[0]);
}
// will output all your img src's within the html string
print_r($origImageSrc);

This command will move all the files in originalfolder to destinationfolder.

MOVE c:\originalfolder\* c:\destinationfolder

(However it wont move any sub-folders to the new location.)

To lookup the instructions for the MOVE command type this in a windows command prompt:

MOVE /?

I solve such queries using this pattern:

SELECT *
FROM t
WHERE t.field=(
  SELECT MAX(t.field) 
  FROM t AS t0 
  WHERE t.group_column1=t0.group_column1
    AND t.group_column2=t0.group_column2 ...)

That is it will select records where the value of a field is at its max value. To apply it to your query I used the common table expression so that I don't have to repeat the JOIN twice:

WITH site_history AS (
  SELECT sites.siteName, sites.siteIP, history.date
  FROM sites
  JOIN history USING (siteName)
)
SELECT *
FROM site_history h
WHERE date=(
  SELECT MAX(date) 
  FROM site_history h0 
  WHERE h.siteName=h0.siteName)
ORDER BY siteName

It's important to note that it works only if the field we're calculating the maximum for is unique. In your example the date field should be unique for each siteName, that is if the IP can't be changed multiple times per millisecond. In my experience this is commonly the case otherwise you don't know which record is the newest anyway. If the history table has an unique index for (site, date), this query is also very fast, index range scan on the history table scanning just the first item can be used.

For anyone experiencing the problem of the info.plist not being included when trying to add localizations, like in Xcode 9.

You need make the info.plist localiazble by going into it and clicking on the localize button in the file inspector, as shown below.

The info.plist will then be included in the file resources for when you go to add new Localizations.

I would recommend using a hash instead of a param string:

data = {id: id, name: name}

If you know the file is in your current directory, I would use:

ls -lt | head

This lists your most recently modified files and directories in order. In fact, I use it so much I have it aliased to 'lh'.

I like this method using fileinput and the 'inplace' method:

import fileinput
for line in fileinput.input(fname, inplace =1):
    line = line.strip()
    if not 'UnwantedWord' in line:
        print(line)

It's a little less wordy than the other answers and is fast enough for

You cannot as there is no file input/output in Javascript. See here for a similar question posted.

str.replace is the wrong function for what you want to do (apart from it being used incorrectly). You want to replace any character of a set with a space, not the whole set with a single space (the latter is what replace does). You can use translate like this:

removeSpecialChars = z.translate ({ord(c): " " for c in "!@#$%^&*()[]{};:,./<>?\|`~-=_+"})

This creates a mapping which maps every character in your list of special characters to a space, then calls translate() on the string, replacing every single character in the set of special characters with a space.

You're attempting to free something that isn't a pointer to a "freeable" memory address. Just because something is an address doesn't mean that you need to or should free it.

There are two main types of memory you seem to be confusing - stack memory and heap memory.

• Stack memory lives in the live span of the function. It's temporary space for things that shouldn't grow too big. When you call the function main, it sets aside some memory for your variables you've declared (p,token, and so on).

• Heap memory lives from when you malloc it to when you free it. You can use much more heap memory than you can stack memory. You also need to keep track of it - it's not easy like stack memory!

You have a few errors:

• You're trying to free memory that's not heap memory. Don't do that.

• You're trying to free the inside of a block of memory. When you have in fact allocated a block of memory, you can only free it from the pointer returned by malloc. That is to say, only from the beginning of the block. You can't free a portion of the block from the inside.

For your bit of code here, you probably want to find a way to copy relevant portion of memory to somewhere else...say another block of memory you've set aside. Or you can modify the original string if you want (hint: char value 0 is the null terminator and tells functions like printf to stop reading the string).

EDIT: The malloc function does allocate heap memory*.

"9.9.1 The malloc and free Functions

The C standard library provides an explicit allocator known as the malloc package. Programs allocate blocks from the heap by calling the malloc function."

~Computer Systems : A Programmer's Perspective, 2nd Edition, Bryant & O'Hallaron, 2011

EDIT 2: * The C standard does not, in fact, specify anything about the heap or the stack. However, for anyone learning on a relevant desktop/laptop machine, the distinction is probably unnecessary and confusing if anything, especially if you're learning about how your program is stored and executed. When you find yourself working on something like an AVR microcontroller as H2CO3 has, it is definitely worthwhile to note all the differences, which from my own experience with embedded systems, extend well past memory allocation.

The following are rough guidelines and educated guesses based on experience. You should timeit or profile your concrete use case to get hard numbers, and those numbers may occasionally disagree with the below.

A list comprehension is usually a tiny bit faster than the precisely equivalent for loop (that actually builds a list), most likely because it doesn't have to look up the list and its append method on every iteration. However, a list comprehension still does a bytecode-level loop:

>>> dis.dis(<the code object for `[x for x in range(10)]`>)
 1           0 BUILD_LIST               0
             3 LOAD_FAST                0 (.0)
       >>    6 FOR_ITER                12 (to 21)
             9 STORE_FAST               1 (x)
            12 LOAD_FAST                1 (x)
            15 LIST_APPEND              2
            18 JUMP_ABSOLUTE            6
       >>   21 RETURN_VALUE

Using a list comprehension in place of a loop that doesn't build a list, nonsensically accumulating a list of meaningless values and then throwing the list away, is often slower because of the overhead of creating and extending the list. List comprehensions aren't magic that is inherently faster than a good old loop.

As for functional list processing functions: While these are written in C and probably outperform equivalent functions written in Python, they are not necessarily the fastest option. Some speed up is expected if the function is written in C too. But most cases using a lambda (or other Python function), the overhead of repeatedly setting up Python stack frames etc. eats up any savings. Simply doing the same work in-line, without function calls (e.g. a list comprehension instead of map or filter) is often slightly faster.

Suppose that in a game that I'm developing I need to draw complex and huge maps using for loops. This question would be definitely relevant, for if a list-comprehension, for example, is indeed faster, it would be a much better option in order to avoid lags (Despite the visual complexity of the code).

Chances are, if code like this isn't already fast enough when written in good non-"optimized" Python, no amount of Python level micro optimization is going to make it fast enough and you should start thinking about dropping to C. While extensive micro optimizations can often speed up Python code considerably, there is a low (in absolute terms) limit to this. Moreover, even before you hit that ceiling, it becomes simply more cost efficient (15% speedup vs. 300% speed up with the same effort) to bite the bullet and write some C.

Separate 'em with a space.

<div class="c1 c2"></div>

It says on the PHP site that multiple queries are NOT permitted (EDIT: This is only true for the mysql extension. mysqli and PDO allow multiple queries) . So you can't do it in PHP, BUT, why can't you just execute that query in another mysql_query call, (like Jon's example)? It should still give you the correct result if you use the same connection. Also, mysql_num_rows may help also.

After seeing how you responded in the comments. It seems like it would be best to use push as others have suggested. This way you don't need to know the indices, but you can still add to the array.

var arr = [];
function funcInJsFile() {
    // Do Stuff
    var obj = {x: 54, y: 10};
    arr.push(obj);
}

In this case, every time you use that function, it will push a new object into the array.

I simply do:

if(document.getElementById("myElementId")){
    alert("Element exists");
} else {
    alert("Element does not exist");
}

It works for me and had no issues with it yet...

I had a similar issue and found that it was much simpler to to get rid of the Excel files as soon as possible. As part of the first steps in my package I used Powershell to extract the data out of the Excel files into CSV files. My own Excel files were simple but here

Extract and convert all Excel worksheets into CSV files using PowerShell

is an excellent article by Tim Smith on extracting data from multiple Excel files and/or multiple sheets.

Once the Excel files have been converted to CSV the data import is much less complicated.

$myvals = get_post_meta( get_the_ID());
foreach($myvals as $key=>$val){
  foreach($val as $vals){
    if ($key=='Youtube'){
       echo $vals 
    }
   }
 }

Key = Youtube videos all meta keys for youtube videos and value

stringstream.str() returns a temporary string object that's destroyed at the end of the full expression. If you get a pointer to a C string from that (stringstream.str().c_str()), it will point to a string which is deleted where the statement ends. That's why your code prints garbage.

You could copy that temporary string object to some other string object and take the C string from that one:

const std::string tmp = stringstream.str();
const char* cstr = tmp.c_str();

Note that I made the temporary string const, because any changes to it might cause it to re-allocate and thus render cstr invalid. It is therefor safer to not to store the result of the call to str() at all and use cstr only until the end of the full expression:

use_c_str( stringstream.str().c_str() );

Of course, the latter might not be easy and copying might be too expensive. What you can do instead is to bind the temporary to a const reference. This will extend its lifetime to the lifetime of the reference:

{
  const std::string& tmp = stringstream.str();   
  const char* cstr = tmp.c_str();
}

IMO that's the best solution. Unfortunately it's not very well known.

The issue is that an Integer is not large enough to store a current date, you need to use a Long.

The date is stored internally as the number of milliseconds since 1/1/1970.

The maximum Integer value is 2147483648, whereas the number of milliseconds since 1970 is currently in the order of 1345618537869

Putting the maximum integer value into a date yields Monday 26th January 1970.

Edit: Code to display division by 1000 as per comment below:

    int i = (int) (new Date().getTime()/1000);
    System.out.println("Integer : " + i);
    System.out.println("Long : "+ new Date().getTime());
    System.out.println("Long date : " + new Date(new Date().getTime()));
    System.out.println("Int Date : " + new Date(((long)i)*1000L));

Integer : 1345619256
Long : 1345619256308
Long date : Wed Aug 22 16:37:36 CST 2012
Int Date : Wed Aug 22 16:37:36 CST 2012

I think you are right. This method is too global...

However - it is a good default for when your AJAX call has no effect on the page itself. (background save for example). ( you can always switch it off for a certain ajax call by passing "global":false - see documentation at jquery

When the AJAX call is meant to refresh part of the page, I like my "loading" images to be specific to the refreshed section. I would like to see which part is refreshed.

Imagine how cool it would be if you could simply write something like :

$("#component_to_refresh").ajax( { ... } ); 

And this would show a "loading" on this section. Below is a function I wrote that handles "loading" display as well but it is specific to the area you are refreshing in ajax.

First, let me show you how to use it

<!-- assume you have this HTML and you would like to refresh 
      it / load the content with ajax -->

<span id="email" name="name" class="ajax-loading">
</span>

<!-- then you have the following javascript --> 

$(document).ready(function(){
     $("#email").ajax({'url':"/my/url", load:true, global:false});
 })

And this is the function - a basic start that you can enhance as you wish. it is very flexible.

jQuery.fn.ajax = function(options)
{
    var $this = $(this);
    debugger;
    function invokeFunc(func, arguments)
    {
        if ( typeof(func) == "function")
        {
            func( arguments ) ;
        }
    }

    function _think( obj, think )
    {
        if ( think )
        {
            obj.html('<div class="loading" style="background: url(/public/images/loading_1.gif) no-repeat; display:inline-block; width:70px; height:30px; padding-left:25px;"> Loading ... </div>');
        }
        else
        {
            obj.find(".loading").hide();
        }
    }

    function makeMeThink( think )
    {
        if ( $this.is(".ajax-loading") )
        {
            _think($this,think);
        }
        else
        {
            _think($this, think);
        }
    }

    options = $.extend({}, options); // make options not null - ridiculous, but still.
    // read more about ajax events
    var newoptions = $.extend({
        beforeSend: function()
        {
            invokeFunc(options.beforeSend, null);
            makeMeThink(true);
        },

        complete: function()
        {
            invokeFunc(options.complete);
            makeMeThink(false);
        },
        success:function(result)
        {
            invokeFunc(options.success);
            if ( options.load )
            {
                $this.html(result);
            }
        }

    }, options);

    $.ajax(newoptions);
};

foreach (Control field in container.Controls)
            {
                if (field is TextBox)
                    ((TextBox)field).Clear();
                else if (field is ComboBox)
                    ((ComboBox)field).SelectedIndex=0;

you'll probably want to look into jquery-ui dialog. it's highly customizable and can be made to work exactly like lightbox/fancybox and supports everything you would need for a contact form from a regular link.

there is even an example with a form.

1. Make sure all versions are same for each projects click each projects and see the version here Project > Properties > Application > Target .NET framework

2. a. Go to Tools > Nuget Package Manager > Package Manager Console Type Update-Package -Reinstall (if not working proceed to 2.b)

   b. THIS IS CRITICAL BUT THE BIGGEST POSSIBILITY THAT WILL WORK. Remove < Target > Maybe with multiple lines < /Target > usually found at the bottom part of .csproj.

3. Save, load and build the solution.

Use CURRENT_TIMESTAMP when you need it, instead OF NOW() (which is MySQL)

String array[] = {"ASDFASDFASDF","AA", "BBB", "CCCC", "DD", "EEDDDAD"};
    List<String> list = Arrays.asList(array);
    Map<Integer, String> map = list.stream()
            .collect(Collectors.toMap(s -> s.length(), s -> s, (x, y) -> {
                System.out.println("Dublicate key" + x);
                return x;
            },()-> new TreeMap<>((s1,s2)->s2.compareTo(s1))));
    System.out.println(map);

Dublicate key AA {12=ASDFASDFASDF, 7=EEDDDAD, 4=CCCC, 3=BBB, 2=AA}

I think you're a little confused. PYTHONPATH sets the search path for importing python modules, not for executing them like you're trying.

PYTHONPATH Augment the default search path for module files. The format is the same as the shell’s PATH: one or more directory pathnames separated by os.pathsep (e.g. colons on Unix or semicolons on Windows). Non-existent directories are silently ignored.

In addition to normal directories, individual PYTHONPATH entries may refer to zipfiles containing pure Python modules (in either source or compiled form). Extension modules cannot be imported from zipfiles.

The default search path is installation dependent, but generally begins with prefix/lib/pythonversion (see PYTHONHOME above). It is always appended to PYTHONPATH.

An additional directory will be inserted in the search path in front of PYTHONPATH as described above under Interface options. The search path can be manipulated from within a Python program as the variable sys.path.

http://docs.python.org/2/using/cmdline.html#envvar-PYTHONPATH

What you're looking for is PATH.

export PATH=$PATH:/home/randy/lib/python 

However, to run your python script as a program, you also need to set a shebang for Python in the first line. Something like this should work:

#!/usr/bin/env python

And give execution privileges to it:

chmod +x /home/randy/lib/python/gbmx.py

Then you should be able to simply run gmbx.py from anywhere.

$argv[0]; // the script name
$argv[1]; // the first parameter
$argv[2]; // the second parameter

If you want to all the script to run regardless of where you call it from (command line or from the browser) you'll want something like the following:

<?php
if ($_GET) {
    $argument1 = $_GET['argument1'];
    $argument2 = $_GET['argument2'];
} else {
    $argument1 = $argv[1];
    $argument2 = $argv[2];
}
?>

To call from command line chmod 755 /var/www/webroot/index.php and use

/usr/bin/php /var/www/webroot/index.php arg1 arg2

To call from the browser, use

http://www.mydomain.com/index.php?argument1=arg1&argument2=arg2

You could use a new annotation to solve this:

@XXXToXXX(targetEntity = XXXX.class, fetch = FetchType.LAZY)

In fact, fetch's default value is FetchType.LAZY too.

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
   ts.tax_status_id, 
   ( select r.recipient_id
     from recipient r
     where r.recipient_code = ?
   )
from tax_status ts
where ts.tax_status_code = ?

The best way with the HTML you have would probably be to use the next function, like so:

var div = $(this).next('.class2');

Since the click handler is happening to the <a>, you could also traverse up to the parent DIV, then search down for the second DIV. You would do this with a combination of parent and children. This approach would be best if the HTML you put up is not exactly like that and the second DIV could be in another location relative to the link:

var div = $(this).parent().children('.class2');

If you wanted the "search" to not be limited to immediate children, you would use find instead of children in the example above.

Also, it is always best to prepend your class selectors with the tag name if at all possible. ie, if only <div> tags are going to have those classes, make the selector be div.class1, div.class2.

There are a lot of good answers. The key is that you must set nestedScrollingEnabled to false. As mentioned above you can do it in java code:

mRecyclerView.setNestedScrollingEnabled(false);

But also you have an opportunity to set the same property in xml code (android:nestedScrollingEnabled="false"):

 <android.support.v7.widget.RecyclerView
 android:id="@+id/recyclerview"
 android:nestedScrollingEnabled="false"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

There are several ways of exploiting this class. You can call either syncGetSystemCpuUsage or syncGetProcessCpuUsage but each is blocking the calling thread. Since a common issue is to monitor the total CPU usage and the CPU use of the current process at the same time, I have designed a class computing both of them. That class contains a dedicated thread. The output management is implementation specific and you need to code your own.

The class can be customized by a few means. The constant CPU_WINDOW defines the depth of a read, i.e. the number of milliseconds between readings and computing of the corresponding CPU load. CPU_REFRESH_RATE is the time between each CPU load measurement. Do not set CPU_REFRESH_RATE to 0 because it will suspend the thread after the first read.

Have you tried putting it in your public folder? Whenever I have images or the like that I need to reference externally, I put it all there.

This is an error caused by importing the wrong module react from 'react' how about you try this: 1st

import React , { Component}  from 'react';

2nd Or you can try this as well:

import React from 'react';
import { render   }  from 'react-dom';

class TechView extends React.Component {

    constructor(props){
       super(props);
       this.state = {
           name:'Gopinath',
       }
    }
    render(){
        return(
            <span>hello Tech View</span>
        );
    }
}

export default TechView;

Import specific methods inside of curly brackets

import { map, tail, times, uniq } from 'lodash';

Pros:

• Only one import line(for a decent amount of functions)
• More readable usage: map() instead of _.map() later in the javascript code.

Cons:

• Every time we want to use a new function or stop using another - it needs to be maintained and managed

eloone did it file by file with

git checkout <commit-hash> <filename>

but you could checkout all files more easily by doing

git checkout <commit-hash> .

You can also use the java.util.Scanner class.

private static void readFileWithScanner() {
    File file = new File("path/to/your/file/file.txt");

    Scanner scan = null;

    try {
        scan = new Scanner(file);

        while (scan.hasNextLine()) {
            String line = scan.nextLine();
            String[] lineArray = line.split(",");
            // do something with lineArray, such as instantiate an object
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } finally {
        scan.close();
    }
}

Looking at :help tabs it doesn't look like vim wants to work the way you do...

Buffers are shared across tabs, so it doesn't seem possible to lock a given buffer to appear only on a certain tab.

It's a good idea, though.

You could probably get the effect you want by using a terminal that supports tabs, like multi-gnome-terminal, then running vim instances in each terminal tab. Not perfect, though...

Looks like you're trying to both inherit the groupId from the parent, and simultaneously specify the parent using an inherited groupId!

In the child pom, use something like this:

<modelVersion>4.0.0</modelVersion>

<parent>
  <groupId>org.felipe</groupId>
  <artifactId>tutorial_maven</artifactId>
  <version>1.0-SNAPSHOT</version>
  <relativePath>../pom.xml</relativePath>
</parent>

<artifactId>tutorial_maven_jar</artifactId>

Using properties like ${project.groupId} won't work there. If you specify the parent in this way, then you can inherit the groupId and version in the child pom. Hence, you only need to specify the artifactId in the child pom.

With Spring 3.1 and Tomcat 7 I got next error:

org.springframework.web.servlet.DispatcherServlet noHandlerFound No mapping found for HTTP request with URI [/baremvc/] in DispatcherServlet with name 'appServlet'

And I needed to add to web.xml next configuration:

<welcome-file-list>
    <welcome-file/>
</welcome-file-list>

And the application worked!

Country is a categorical variable and I want to see how many occurences of country exist in the data set. In other words, how many records/attendees are from each Country

Just to clarify, and for anyone else that may be pulling their hair out...

If you are using git bash on Windows, set node_env=production&& node whatever.js does not seem to work. Instead, use the native cmd. Then, using set node_env=production&& node whatever.jsworks as expected.

My use case:

I develop on Windows because my workflow is a lot faster, but I needed to make sure that my application's development-specific middleware were not firing in the production environment.

In addition to @sbedulin (Greeting, lovely Windows users!)

The general path on Windows should be

%USERPROFILE%\AppData\Local\atom\bin

If you are using a bash emulator like babun. You'd better checkout the shell files, which only available in the real app folders

/c/User/<username>/AppData/Local/atom/app-<version>/resources/cli/apm.sh # or atom.sh

This is the way I've been doing this sort of stuff. Angular tends to favor declarative manipulation of the dom rather than a imperative one(at least that's the way I've been playing with it).

The markup

<table class="table">
  <thead>
    <tr>
      <th>
        <input type="checkbox" 
          ng-click="selectAll($event)"
          ng-checked="isSelectedAll()">
      </th>
      <th>Title</th>
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="e in entities" ng-class="getSelectedClass(e)">
      <td>
        <input type="checkbox" name="selected"
          ng-checked="isSelected(e.id)"
          ng-click="updateSelection($event, e.id)">
      </td>
      <td>{{e.title}}</td>
    </tr>
  </tbody>
</table>

And in the controller

var updateSelected = function(action, id) {
  if (action === 'add' && $scope.selected.indexOf(id) === -1) {
    $scope.selected.push(id);
  }
  if (action === 'remove' && $scope.selected.indexOf(id) !== -1) {
    $scope.selected.splice($scope.selected.indexOf(id), 1);
  }
};

$scope.updateSelection = function($event, id) {
  var checkbox = $event.target;
  var action = (checkbox.checked ? 'add' : 'remove');
  updateSelected(action, id);
};

$scope.selectAll = function($event) {
  var checkbox = $event.target;
  var action = (checkbox.checked ? 'add' : 'remove');
  for ( var i = 0; i < $scope.entities.length; i++) {
    var entity = $scope.entities[i];
    updateSelected(action, entity.id);
  }
};

$scope.getSelectedClass = function(entity) {
  return $scope.isSelected(entity.id) ? 'selected' : '';
};

$scope.isSelected = function(id) {
  return $scope.selected.indexOf(id) >= 0;
};

//something extra I couldn't resist adding :)
$scope.isSelectedAll = function() {
  return $scope.selected.length === $scope.entities.length;
};

EDIT: getSelectedClass() expects the entire entity but it was being called with the id of the entity only, which is now corrected

You can execute it just as you select a table using SELECT clause. In addition you can provide parameters within parentheses.

Try with below syntax:

SELECT * FROM yourFunctionName(parameter1, parameter2)

<input type="date" id="myDate"  />

<script type="text/javascript">
function SetDate()
{
var date = new Date();

var day = date.getDate();
var month = date.getMonth() + 1;
var year = date.getFullYear();

if (month < 10) month = "0" + month;
if (day < 10) day = "0" + day;

var today = year + "-" + month + "-" + day;


document.getElementById('myDate').value = today;
}
</script>

<body onload="SetDate();">

Never is a good practice to pass the password argument directly from the command line, it is saved in the ~/.bash_history file and can be accessible from other applications.

Use this instead:

mysql -u user --host host --port 9999 database_name < /scripts/script.sql -p
Enter password:

This is how I implemented Spring MVC Multipart Request with JSON Data.

Multipart Request with JSON Data (also called Mixed Multipart):

Based on RESTful service in Spring 4.0.2 Release, HTTP request with the first part as XML or JSON formatted data and the second part as a file can be achieved with @RequestPart. Below is the sample implementation.

Java Snippet:

Rest service in Controller will have mixed @RequestPart and MultipartFile to serve such Multipart + JSON request.

@RequestMapping(value = "/executesampleservice", method = RequestMethod.POST,
    consumes = {"multipart/form-data"})
@ResponseBody
public boolean executeSampleService(
        @RequestPart("properties") @Valid ConnectionProperties properties,
        @RequestPart("file") @Valid @NotNull @NotBlank MultipartFile file) {
    return projectService.executeSampleService(properties, file);
}

Front End (JavaScript) Snippet:

1. Create a FormData object.

2. Append the file to the FormData object using one of the below steps.

   1. If the file has been uploaded using an input element of type "file", then append it to the FormData object. formData.append("file", document.forms[formName].file.files[0]);
   2. Directly append the file to the FormData object. formData.append("file", myFile, "myfile.txt"); OR formData.append("file", myBob, "myfile.txt");

3. Create a blob with the stringified JSON data and append it to the FormData object. This causes the Content-type of the second part in the multipart request to be "application/json" instead of the file type.

4. Send the request to the server.

5. Request Details:
   Content-Type: undefined. This causes the browser to set the Content-Type to multipart/form-data and fill the boundary correctly. Manually setting Content-Type to multipart/form-data will fail to fill in the boundary parameter of the request.

Javascript Code:

formData = new FormData();

formData.append("file", document.forms[formName].file.files[0]);
formData.append('properties', new Blob([JSON.stringify({
                "name": "root",
                "password": "root"                    
            })], {
                type: "application/json"
            }));

Request Details:

method: "POST",
headers: {
         "Content-Type": undefined
  },
data: formData

Request Payload:

Accept:application/json, text/plain, */*
Content-Type:multipart/form-data; boundary=----WebKitFormBoundaryEBoJzS3HQ4PgE1QB

------WebKitFormBoundaryvijcWI2ZrZQ8xEBN
Content-Disposition: form-data; name="file"; filename="myfile.txt"

Check out this POC or MVP of running in parallel one-host-from-every-group (for all hosts) https://github.com/sirkubax/szkolenie3/tree/master/playbooks/playgroups

you may get the inspiration

With ES6 syntax

import mongoose from "mongoose";

// Generate a new new ObjectId
const newId2 = new mongoose.Types.ObjectId();
// Convert string to ObjectId
const newId = new mongoose.Types.ObjectId('56cb91bdc3464f14678934ca');

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

I think you are looking for this ?

$('#your_id').html('<p>name</p><p><span style="font-size:xx-small;">ajde</span></p><p><em>da</em></p>').text();

#/bin/bash
# $1 is the file name
# usage: this_script  <filename>
IP_address="xx.xxx.xx.xx"
username="username"
domain=my.ftp.domain
password=password

echo "
 verbose
 open $IP_address
 USER $username $password
 put $1
 bye
" | ftp -n > ftp_$$.log

Below solution perfectly works for spring boot application.

Controller:

@GetMapping("user/getAllInactiveUsers")
List<User> getAllInactiveUsers(@RequestParam("date") @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss") Date dateTime) {
    return userRepository.getAllInactiveUsers(dateTime);
}

So in the caller (in my case its a web flux), we need to pass date time in this("yyyy-MM-dd HH:mm:ss") format.

Caller Side:

public Flux<UserDto> getAllInactiveUsers(String dateTime) {
    Flux<UserDto> userDto = RegistryDBService.getDbWebClient(dbServiceUrl).get()
            .uri("/user/getAllInactiveUsers?date={dateTime}", dateTime).retrieve()
            .bodyToFlux(User.class).map(UserDto::of);
    return userDto;
}

Repository:

@Query("SELECT u from User u  where u.validLoginDate < ?1 AND u.invalidLoginDate < ?1 and u.status!='LOCKED'")
List<User> getAllInactiveUsers(Date dateTime);

Cheers!!

You could also use JDBC to achieve this. Let's create a sample csv file.

write.table(x=mtcars, file="mtcars.csv", sep=",", row.names=F, col.names=T) # create example csv file

Download and save the the CSV JDBC driver from this link: http://sourceforge.net/projects/csvjdbc/files/latest/download

> library(RJDBC)

> path.to.jdbc.driver <- "jdbc//csvjdbc-1.0-18.jar"
> drv <- JDBC("org.relique.jdbc.csv.CsvDriver", path.to.jdbc.driver)
> conn <- dbConnect(drv, sprintf("jdbc:relique:csv:%s", getwd()))

> head(dbGetQuery(conn, "select * from mtcars"), 3)

Here is an example of the wget script in action:

wget -q -O /dev/null "http://example.com/cronjob.php" > /dev/null 2>&1

Using -O parameter like the above means that the output of the web request will be sent to STDOUT (standard output).

And the >/dev/null 2>&1 will instruct standard output to be redirected to a black hole. So no message from the executing program is returned to the screen.

How about add the strings to a hashtable where the value is an index:

  Hashtable<String, Integer> itemIndex = new Hashtable<>();
  itemIndex.put("First String",1);
  itemIndex.put("Second String",2);
  itemIndex.put("Third String",3);

  int indexOfThirdString = itemIndex.get("Third String");

With git there is a https format

https://github.com/equivalent/we_demand_serverless_ruby.git

This format accepts User + password

https://bot-user:[email protected]/equivalent/we_demand_serverless_ruby.git

So what you can do is create a new user that will be used just as a bot, add only enough permissions that he can just read the repository you want to load in NPM modules and just have that directly in your packages.json

 Github > Click on Profile > Settings > Developer settings > Personal access tokens > Generate new token

In Select Scopes part, check the on repo: Full control of private repositories

This is so that token can access private repos that user can see

Now create new group in your organization, add this user to the group and add only repositories that you expect to be pulled this way (READ ONLY permission !)

You need to be sure to push this config only to private repo

Then you can add this to your / packages.json (bot-user is name of user, xxxxxxxxx is the generated personal token)

// packages.json


{
  // ....
    "name_of_my_lib": "https://bot-user:[email protected]/ghuser/name_of_my_lib.git"
  // ...
}

You can just use strstr() from <string.h>

$ man strstr

Microsoft should advertise this functionality of SSMS 2008. The feature you are looking for is built into the Generate Script utility, but the functionality is turned off by default and must be enabled when scripting a table.

This is a quick run through to generate the INSERT statements for all of the data in your table, using no scripts or add-ins to SQL Management Studio 2008:

1. Right-click on the database and go to Tasks > Generate Scripts.
2. Select the tables (or objects) that you want to generate the script against.
3. Go to Set scripting options tab and click on the Advanced button.
4. In the General category, go to Type of data to script
5. There are 3 options: Schema Only, Data Only, and Schema and Data. Select the appropriate option and click on OK.

You will then get the CREATE TABLE statement and all of the INSERT statements for the data straight out of SSMS.

If you're using the GitHub desktop application, there is a synchronise button on the top right corner. Click on it then Update from <original repo> near top left.

If there are no changes to be synchronised, this will be inactive.

Here are some screenshots to make this easy.

First, I strongly suggest to use a Library or Framework to do your Javascript. But just for something very very simple, or for the fun to learn, it is ok. (you can use jquery, underscore, knockoutjs, angular)

Second, it is not advised to bind directly to onclick, my first suggestion goes in that way too.

That's said What you need is to modify the src of a img in your page.

In the place where you want your image displayed, you should insert a img tag like this:

Next, you need to modify the onclick to update the src attribute. The easiest way I can think of is like his

onclick=""document.getElementById('image-placeholder').src = 'http://webpage.com/images/' + document.getElementById('imagename').value + '.png"

Then again, it is not the best way to do it, but it is a start. I recommend you to try jQuery and see how can you accomplish the same whitout using onclick (tip... check the section on jquery about events)

I did a simple fiddle as a example of your poblem using some google logos... type 4 o 3 in the box and you'll two images of different size. (sorry.. I have no time to search for better images as example)

You probably meant this:

require 'active_support/core_ext' # for titleize

myHash = {company_name:"MyCompany", street:"Mainstreet", postcode:"1234", city:"MyCity", free_seats:"3"}

def cleanup string
  string.titleize
end

def format(hash)
  output = {}
  output[:company_name] = cleanup(hash[:company_name])
  output[:street] = cleanup(hash[:street])
  output
end

format(myHash) # => {:company_name=>"My Company", :street=>"Mainstreet"}

Please read documentation on Hash#each

You could switch the onClick event handler on the button to an onSubmit handler on the form:

render : function() {
      return (
        <form onSubmit={this.handleLogin}>
          <input type="text" name="email" placeholder="Email" />
          <input type="password" name="password" placeholder="Password" />
          <button type="submit">Login</button>
        </form>
      );
    },

Then you can make use of FormData to parse the form (and construct a JSON object from its entries if you want).

handleLogin: function(e) {
   const formData = new FormData(e.target)
   const user = {}

   e.preventDefault()

   for (let entry of formData.entries()) {
       user[entry[0]] = entry[1]
   }

   // Do what you will with the user object here
}

Json has a method called containsKey().

You can use it to check if a certain key is contained in the Json set.

File jsonInputFile = new File("jsonFile.json"); 
InputStream is = new FileInputStream(jsonInputFile);
JsonReader reader = Json.createReader(is);
JsonObject frameObj = reader.readObject();
reader.close();

if frameObj.containsKey("person") {
      //Do stuff
}

I came across this PHP diff class by Chris Boulton based on Python difflib which could be a good solution:

PHP Diff Lib

Although this question has an accepted answer but I think this is a much cleaner way to achieve the desired output

<select required>
<option value="">Select</option>
<option>English</option>
<option>Spanish</option>
</select>

The required attribute in makes it mandatory to select an option from the list.

value="" inside the option tag combined with the required attribute in select tag makes selection of 'Select' option not permissible, thus achieving the required output

In kotlin you could do it like this:

val backgroundColor = R.color.whatever_color_you_like
view.setBackgroundColor(getColorCompat(backgroundColor))

Where getColorCompat() is an extension function:

/**
 * Extension method to provide simpler access to {@link ContextCompat#getColor(int)}.
 */

 fun Context.getColorCompat(color: Int) = ContextCompat.getColor(this, color)

Try this, works for me: ls -d /a/b/c/*

JavaSE and JavaEE both are computing platform which allows the developed software to run.

There are three main computing platform released by Sun Microsystems, which was eventually taken over by the Oracle Corporation. The computing platforms are all based on the Java programming language. These computing platforms are:

Java SE, i.e. Java Standard Edition. It is normally used for developing desktop applications. It forms the core/base API.

Java EE, i.e. Java Enterprise Edition. This was originally known as Java 2 Platform, Enterprise Edition or J2EE. The name was eventually changed to Java Platform, Enterprise Edition or Java EE in version 5. Java EE is mainly used for applications which run on servers, such as web sites.

Java ME, i.e. Java Micro Edition. It is mainly used for applications which run on resource constrained devices (small scale devices) like cell phones, most commonly games.

One option would be to pass the whole array and the start and end indices, and iterate between those instead of iterating over the whole array passed.

void method1(byte[] array) {
    method2(array,4,5);
}
void method2(byte[] smallarray,int start,int end) {
    for ( int i = start; i <= end; i++ ) {
        ....
    }
}

If the folder is already writable so thats not the problem.

You can also just navigate to /www/projet_etienne/app/cache/ and manualy remove the folders in there (dev, dev_new, dev_old).

Make sure to SAVE a copy of those folder somewhere to put back if this doesn't fix the problem

I know this is not the way it should be done but it worked for me a couple of times now.
