Programs & Examples On #Vp8

Extremeandy has mentioned as of Chrome 66 autoplay video has been disabled.

After looking into this I found that muted videos are still able to be autoplayed. In my case the video didn't have any audio, but adding muted to the video tag has fixed it:

Hopefully this will help others also.

I've been having similar issues of a video not playing in IE11 on Windows 8.1. What I didn't realize was that I was running an N version of Windows, meaning no media features were installed. After installing the Media Feature Pack for N and KN versions of Windows 8.1 and rebooting my PC it was working fine.

As a side-note, the video worked fine in Chrome, Firefox, etc, since those browsers properly fell back to the webm file.

To all of you who got here and did not found the right solution, i found out that the mp4 video needs to fit a specific format.

My Problem was that i got an 1920x1080 video which wont load under Chrome (under Firefox it worked like a charm). After hours of searching i finaly managed to get hang of the problem, the first few streams where 1912x1088 so Chrome wont play it ( i got the exact stream size from the tool MediaInfo). So to fix it i just resized it to 1920x1080 and it worked.

import base64
coded_string = '''Q5YACgA...'''
base64.b64decode(coded_string)

worked for me. At the risk of pasting an offensively-long result, I got:

>>> base64.b64decode(coded_string)

What problem are you having, specifically?

I found a good article about using the WMP with Firefox on MSDN.

Based on MSDN's article and after doing some trials and errors, I found using JavaScript is better than using conditional comments or nested "EMBED/OBJECT" tags.

I made a JS function that generate WMP object based on given arguments:

<script type="text/javascript">
    function generateWindowsMediaPlayer(
        holderId,   // String
        height,     // Number
        width,      // Number
        videoUrl    // String
        // you can declare more arguments for more flexibility
        ) {
        var holder = document.getElementById(holderId);

        var player = '<object ';
        player += 'height="' + height.toString() + '" ';
        player += 'width="' + width.toString() + '" ';

        videoUrl = encodeURI(videoUrl); // Encode for special characters

        if (navigator.userAgent.indexOf("MSIE") < 0) {
            // Chrome, Firefox, Opera, Safari
            //player += 'type="application/x-ms-wmp" '; //Old Edition
            player += 'type="video/x-ms-wmp" '; //New Edition, suggested by MNRSullivan (Read Comments)
            player += 'data="' + videoUrl + '" >';
        }
        else {
            // Internet Explorer
            player += 'classid="clsid:6BF52A52-394A-11d3-B153-00C04F79FAA6" >';
            player += '<param name="url" value="' + videoUrl + '" />';
        }

        player += '<param name="autoStart" value="false" />';
        player += '<param name="playCount" value="1" />';
        player += '</object>';

        holder.innerHTML = player;
    }
</script>

Then I used that function by writing some markups and inline JS like these:

<div id='wmpHolder'></div>

<script type="text/javascript">        
    window.addEventListener('load', generateWindowsMediaPlayer('wmpHolder', 240, 320, 'http://mysite.com/path/video.ext'));
</script>

You can use jQuery.ready instead of window load event to making the codes more backward-compatible and cross-browser.

I tested the codes over IE 9-10, Chrome 27, Firefox 21, Opera 12 and Safari 5, on Windows 7/8.

So that its value can easily contain quotes and <> characters and respect whitespace and newlines.

The following HTML code successfully pass the w3c validator and displays <,> and & without the need to encode them. It also respects the white spaces.

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8" />
    <title>Yes I can</title>
</head>
<body>
    <textarea name="test">
        I can put < and > and & signs in 
        my textarea without any problems.
    </textarea>
</body>
</html>

Both will work but xhtml standard requires you to specify the type too:

<script type="text/javascript">..</script> 

<!ELEMENT SCRIPT - - %Script;          -- script statements -->
<!ATTLIST SCRIPT
  charset     %Charset;      #IMPLIED  -- char encoding of linked resource --
  type        %ContentType;  #REQUIRED -- content type of script language --
  src         %URI;          #IMPLIED  -- URI for an external script --
  defer       (defer)        #IMPLIED  -- UA may defer execution of script --
  >

type = content-type [CI] This attribute specifies the scripting language of the element's contents and overrides the default scripting language. The scripting language is specified as a content type (e.g., "text/javascript"). Authors must supply a value for this attribute. There is no default value for this attribute.

Notices the emphasis above.

http://www.w3.org/TR/html4/interact/scripts.html

Note: As of HTML5 (far away), the type attribute is not required and is default.

1) I guess not, at least not from Java.
2)

ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
MemoryInfo mi = new MemoryInfo();
activityManager.getMemoryInfo(mi);
Log.i("memory free", "" + mi.availMem);

window.onload = function() {
    var userImage = document.getElementById('imageOtherUser');
    var hangoutButton = document.getElementById("hangoutButtonId");
    userImage.onclick = function() {
       hangoutButton.click(); // this will trigger the click event
    };
};

this will do the trick

Update 07/07/2014 - The answer based on my answer, by Grim..., is a better solution as it improves on my solution below, so I'd suggest using that.

You can do this without listing all the columns with the following syntax:

CREATE TEMPORARY TABLE tmptable SELECT * FROM table WHERE primarykey = 1;
UPDATE tmptable SET primarykey = 2 WHERE primarykey = 1;
INSERT INTO table SELECT * FROM tmptable WHERE primarykey = 2;

You may decide to change the primary key in another way.

Have the element display as a block:

display: block;

Let me add my 2¢, it's my job to get good and clean data for a hedge-fund, I've seen quite a lot of data feeds and historical data providers. This is mainly about US stock data.

To start with, if you have some money don't bother with downloading data from Yahoo, get the end of day data straight from CSI data, this is where Yahoo gets their EOD data as well AFAIK. They have an API where you can extract the data to whatever format you want. I think the yearly subscription for data is a few $100 bucks.

The main problem with downloading data from a free service is that you only get stocks that still exist, this is called Survivorship Bias and can give you wrong results if you look at many stocks, because you'll only include the ones that made it so far and not the ones that were de-listed.

For playing around with some intraday data I'd look into IQFeed, they provide several APIs to extract historical data, although they are mainly an outfit for real-time feeds. But here there are quite a few options, some brokers even provide historical data downloads via their APIs, so just pick your poison.

BUT usually all of this data is not very clean, once you really start back testing you'll see that certain stocks are missing or appear as two different symbols, or stock splits are not properly accounted for, etc. And then you realize that historical dividend data is need as well and so you start running in circles, patching data together from 100 different data sources and so on. So to start with a "discount" data feed will do, but as soon as you run more comprehensive backtests you might run into problems depending on what you do. If you just look at, let's say, the S&P 500 stocks this will not be so much a problem though and a "cheap" intraday feed will do.

What you will not find is free intraday data. I mean you might find some examples, I'm sure there's somewhere 5 years of MSFT tick data floating around but that will not get you very far.

Then, if you need the real stuff (level II order book, all ticks as they have happened at all exchanges) one "affordable", yet excellent option is Nanex. They'll actually ship you a drive with terabytes of data. If I remember right its about $3k-4K per year of data. But trust me, once you understand how hard it is to get good intraday data, you won't think this is very much money at all.

Not to discourage you but to get good data is hard, so hard in fact that many hedge-funds and banks spend hundreds of thousands of dollars a month to get data they can trust. Again, you can start somewhere and then go from there but it's good to see it a bit in context.

Edit: The answer above is from my own experience. This write-up from Caltech about available data feeds will give more insights, and especially recommends QuantQuote.

If calculating with dates summertime will cause often 1 uur more or one hour less than midnight (CEST). This causes 1 day difference when dates return. So the dates have to round to the nearest midnight. So the code will be (ths to jamisOn):

    var d = new Date();
    if(d.getHours() < 12) {
    d.setHours(0,0,0,0); // previous midnight day
    } else {
    d.setHours(24,0,0,0); // next midnight day
    }

It is very simple. check for string empty condition in while condition.

1. You can use strlen function to check for the string length.

   #include<stdio.h>
   #include <string.h>   
   
   int main()
   {
       char url[63] = {'\0'};
       do
       {
           printf("Enter a URL: ");
           scanf("%s", url);
           printf("%s", url);
       } while (strlen(url)<=0);
       return(0);
   }
   

2. check first character is '\0'

   #include <stdio.h>    
   #include <string.h>
   
   int main()
   {        
       char url[63] = {'\0'};
   
       do
       {
           printf("Enter a URL: ");
           scanf("%s", url);
           printf("%s", url);
       } while (url[0]=='\0');
   
       return(0);
   }

be the correct way, mathematically speaking?

Use logging module (http://docs.python.org/library/logging.html):

import logging

logger = logging.getLogger('scope.name')

file_log_handler = logging.FileHandler('logfile.log')
logger.addHandler(file_log_handler)

stderr_log_handler = logging.StreamHandler()
logger.addHandler(stderr_log_handler)

# nice output format
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
file_log_handler.setFormatter(formatter)
stderr_log_handler.setFormatter(formatter)

logger.info('Info message')
logger.error('Error message')

I would filter the files server side, because there are tools, such as Live HTTP Headers on Firefox that would allow to upload any file, including a shell. People could hack your site. Do it server site, to be safe.

You're looking for an ellipsoid formula.

The best place I've found to start coding is based on the Geo::Ellipsoid library from CPAN. It gives you a baseline to create your tests off of and to compare your results with its results. I used it as the basis for a similar library for PHP at my previous employer.

Geo::Ellipsoid

Take a look at the location method. Call it twice and you've got your bbox.

You didn't post what language you were using. There may already be a geocoding library available for you.

Oh, and if you haven't figured it out by now, Google maps uses the WGS84 ellipsoid.

If you are using post as a model (without dependency injection), you can also do:

$posts = Post::orderBy('id', 'DESC')->get();

You could use a library called requests.

import requests
r = requests.get("http://example.com/foo/bar")

This is quite easy. Then you can do like this:

>>> print(r.status_code)
>>> print(r.headers)
>>> print(r.content)

For JavaScript arrays, you use Both push() and concat() function.

var array = [1, 2, 3];
array.push(4, 5);         //use push for appending a single array.




var array1 = [1, 2, 3];
var array2 = [4, 5, 6];

var array3 = array1.concat(array2);   //It is better use concat for appending more then one array.

It is a tradition to use Turbo C for graphic in C/C++. But it’s also a pain in the neck. We are using Code::Blocks IDE, which will ease out our work.

Steps to run graphics code in CodeBlocks:

1. Install Code::Blocks
2. Download the required header files
3. Include graphics.h and winbgim.h
4. Include libbgi.a
5. Add Link Libraries in Linker Setting
6. include graphics.h and Save code in cpp extension

To test the setting copy paste run following code:

#include <graphics.h>
int main( )
{
    initwindow(400, 300, "First Sample");
    circle(100, 50, 40);
    while (!kbhit( ))
    {
        delay(200);
    }
    return 0;
}

Here is a complete setup instruction for Code::Blocks

Grain Script is superb and save my day. Meanwhile mysql is depreciated and I rewrote Grain answer using PDO.

Implement the Comparable interface on your customObject.

string result = DateTime.Now.Date.AddDays(-1).ToString("yyyy-MM-dd");

For checking one date is after another by using isAfter() method.

moment('2020-01-20').isAfter('2020-01-21'); // false
moment('2020-01-20').isAfter('2020-01-19'); // true

For checking one date is before another by using isBefore() method.

moment('2020-01-20').isBefore('2020-01-21'); // true
moment('2020-01-20').isBefore('2020-01-19'); // false

For checking one date is same as another by using isSame() method.

moment('2020-01-20').isSame('2020-01-21'); // false
moment('2020-01-20').isSame('2020-01-20'); // true

Another example for vertically and horizontally centered div or any object(s):

 var obj = $("#divID");
 var halfsc = $(window).height()/2;
 var halfh = $(obj).height() / 2; 

 var halfscrn = screen.width/2;
 var halfobj =$(obj).width() / 2; 

 var goRight =  halfscrn - halfobj ;
 var goBottom = halfsc - halfh;

 $(obj).css({marginLeft: goRight }).css({marginTop: goBottom });

Android studio also create the apk file on every time compile the program, just go to your workspace folder and find app->build->outputs-> then you can see the apk file.

Here is another way using list comprehension (some people might find it debatable). It is very approachable for simple tests, e.g. comparisons on object attributes (which I need a lot):

el = [x for x in mylist if x.attr == "foo"][0]

Of course this assumes the existence (and, actually, uniqueness) of a suitable element in the list.

with open(fpath, 'rb') as myfile:
    fstr = myfile.read()

I encounter this error because the file is empty. This answer may not a correct answer for this question but should give developers a hint like me.

If you use the <a> tag, do not forget to use the entire url which leads to the file -- i.e.:

<a href="http://www.example.com/folder1/file.doc">Download</a>

Hi you should try the string split method:

i = "Hello world"
output = i.split()

j = 'is not enough'

Try this

SELECT distinct id
FROM  (SELECT id, ROW_NUMBER() OVER (ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t

Or use RANK() instead of row number and select records DISTINCT rank

SELECT id
FROM  (SELECT id, ROW_NUMBER() OVER (PARTITION BY  id ORDER BY  id) AS RowNum
      FROM table
      WHERE fid = 64) t
WHERE t.RowNum=1

This also returns the distinct ids

// src/main/com.blabla/command/CustomCommand.kt

@ShellComponent
public class CustomCommand {
    private val logger = KotlinLogging.logger {}

    @ShellMethod("Import, create and update data from CSV")
    public fun importCsv(@ShellOption() file: String) {
        logger.info("Hi")
    }
}

And everything boot normally ending up with a shell with my custom command available.

If you're doing the check inside the View, put the value in the ViewBag.

In your controller:

ViewBag["parameterName"] = Request["parameterName"];

It's worth noting that the Request and Response properties are exposed by the Controller class. They have the same semantics as HttpRequest and HttpResponse.

I'm using python 3.4, requests 2.19.1:

'urllib3' is the logger to get now (no longer 'requests.packages.urllib3'). Basic logging will still happen without setting http.client.HTTPConnection.debuglevel

To use Infinity, you can use Double which supports Infinity: -

    System.out.println(Double.POSITIVE_INFINITY);
    System.out.println(Double.POSITIVE_INFINITY * -1);
    System.out.println(Double.NEGATIVE_INFINITY);

    System.out.println(Double.POSITIVE_INFINITY - Double.NEGATIVE_INFINITY);
    System.out.println(Double.POSITIVE_INFINITY - Double.POSITIVE_INFINITY);

OUTPUT: -

Infinity
-Infinity
-Infinity

Infinity 
NaN

I really liked Joey's method, but I thought I'd expand upon it a bit.

In this approach, you can run the code multiple times and not worry about the old date value "sticking around" because it's already defined.

Each time you run this batch file, it will output an ISO 8601 compatible combined date and time representation.

FOR /F "skip=1" %%D IN ('WMIC OS GET LocalDateTime') DO (SET LIDATE=%%D & GOTO :GOT_LIDATE)
:GOT_LIDATE
SET DATETIME=%LIDATE:~0,4%-%LIDATE:~4,2%-%LIDATE:~6,2%T%LIDATE:~8,2%:%LIDATE:~10,2%:%LIDATE:~12,2%
ECHO %DATETIME%

In this version, you'll have to be careful not to copy/paste the same code to multiple places in the file because that would cause duplicate labels. You could either have a separate label for each copy, or just put this code into its own batch file and call it from your source file wherever necessary.

You can use:

$("#tagscloud span").text("Your text here");

The same code will also work for the second case. You could also use:

$("#tagscloud #WebPartCaptionWPQ2").text("Your text here");

The other reason can be a firewall. We had same issue even with

jupyter notebook --ip xx.xx.xx.xxx --port xxxx.

Then it turns out to be a firewall on our new centOS7.

" Raheem Shaik ".strip

It will removes left & right side spaces. This code would give us: "Raheem Shaik"

Authentication is the process of verifying the proclaimed identity.

• e.g. username/password

Usually followed by authorization, which is the approval that you can do this and that.

• e.g. permissions

Getting into a non-password protected Java keystore and changing the password can be done with a help of Java programming language itself.

That article contains the code for that:

pyspark.sql.functions.split() is the right approach here - you simply need to flatten the nested ArrayType column into multiple top-level columns. In this case, where each array only contains 2 items, it's very easy. You simply use Column.getItem() to retrieve each part of the array as a column itself:

split_col = pyspark.sql.functions.split(df['my_str_col'], '-')
df = df.withColumn('NAME1', split_col.getItem(0))
df = df.withColumn('NAME2', split_col.getItem(1))

The result will be:

col1 | my_str_col | NAME1 | NAME2
-----+------------+-------+------
  18 |  856-yygrm |   856 | yygrm
 201 |  777-psgdg |   777 | psgdg

I am not sure how I would solve this in a general case where the nested arrays were not the same size from Row to Row.

There is the troublesome case where the object could be a string. The below extension method code handles all cases. Here's how you would use it:

    static void Main(string[] args)
    {
        object number = DBNull.Value;

        int newNumber = number.SafeDBNull<int>();

        Console.WriteLine(newNumber);
    }



    public static T SafeDBNull<T>(this object value, T defaultValue) 
    {
        if (value == null)
            return default(T);

        if (value is string)
            return (T) Convert.ChangeType(value, typeof(T));

        return (value == DBNull.Value) ? defaultValue : (T)value;
    } 

    public static T SafeDBNull<T>(this object value) 
    { 
        return value.SafeDBNull(default(T)); 
    } 

The easiest way I found is just to redirect the requests that trigger 404 to the client. This is done by adding an hashtag even when $locationProvider.html5Mode(true) is set.

This trick works for environments with more Web Application on the same Web Site and requiring URL integrity constraints (E.G. external authentication). Here is step by step how to do

index.html

Set the <base> element properly

<base href="@(Request.ApplicationPath + "/")">

web.config

First redirect 404 to a custom page, for example "Home/Error"

<system.web>
    <customErrors mode="On">
        <error statusCode="404" redirect="~/Home/Error" />
    </customErrors>
</system.web>

Home controller

Implement a simple ActionResult to "translate" input in a clientside route.

public ActionResult Error(string aspxerrorpath) {
    return this.Redirect("~/#/" + aspxerrorpath);
}

This is the simplest way.

It is possible (advisable?) to enhance the Error function with some improved logic to redirect 404 to client only when url is valid and let the 404 trigger normally when nothing will be found on client. Let's say you have these angular routes

.when("/", {
    templateUrl: "Base/Home",
    controller: "controllerHome"
})
.when("/New", {
    templateUrl: "Base/New",
    controller: "controllerNew"
})
.when("/Show/:title", {
    templateUrl: "Base/Show",
    controller: "controllerShow"
})

It makes sense to redirect URL to client only when it start with "/New" or "/Show/"

public ActionResult Error(string aspxerrorpath) {
    // get clientside route path
    string clientPath = aspxerrorpath.Substring(Request.ApplicationPath.Length);

    // create a set of valid clientside path
    string[] validPaths = { "/New", "/Show/" };

    // check if clientPath is valid and redirect properly
    foreach (string validPath in validPaths) {
        if (clientPath.StartsWith(validPath)) {
            return this.Redirect("~/#/" + clientPath);
        }
    }

    return new HttpNotFoundResult();
}

This is just an example of improved logic, of course every web application has different needs

It's a subtle difference, but this works fine for me:

$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);

Notice, the difference between getColumnDimensionByColumn and getColumnDimension

Also, I'm not even setting AutoSize and it works fine.

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.

Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.

If you already installed in your eclipse you can solve this problem below,

Go to Windows -> Install New Software and find your android plugin address

Check all lists and re-install your android plugin for eclipse

I solved it like this

If you're rolling your own modules specific to your application, you can either:

• Keep those (and only those) in your application's /node_modules folder and move out all the other dependencies to parent ../node_modules folder. This will work because of how NodeJS CommonJS modules system works by moving up to the parent directory, and so on, until the root of the tree is reached. See: https://nodejs.org/api/modules.html

• Or gitignore all /node_modules/* except your /node_modules/your-modules. See: Make .gitignore ignore everything except a few files

This use case is pretty awesome. It lets you keep modules you created specifically for your application nicely with it and doesn't clutter with dependencies which can be installed later.

In Angular 7 works perfect

HTML

<button (click)="scroll(target)">Click to scroll</button>
<div #target>Your target</div>

In component

scroll(el: HTMLElement) {
    el.scrollIntoView({behavior: 'smooth'});
}

Karan Bhandari's answer is good, but the AccountController added in a project is very likely a Mvc.Controller. To convert his answer for use in an ApiController change HttpContext.Current.GetOwinContext() to Request.GetOwinContext() and make sure you have added the following 2 using statements:

using Microsoft.AspNet.Identity;
using Microsoft.AspNet.Identity.Owin;

I've made a jQuery plugin for working DRY:

$.fn.toggle2classes = function(class1, class2){
  if( !class1 || !class2 )
    return this;

  return this.each(function(){
    var $elm = $(this);

    if( $elm.hasClass(class1) || $elm.hasClass(class2) )
      $elm.toggleClass(class1 +' '+ class2);

    else
      $elm.addClass(class1);
  });
};

You can just try it here, copy and run this in the console and then try:

$('body').toggle2classes('a', 'b');

I would do it this way. Assuming I have a JSON of movies ...

movies.forEach((obj) => {
  Object.entries(obj).forEach(([key, value]) => {
    console.log(`${key} ${value}`);
  });
});

From where did you get the idea that you need to free(token) and free(tk)? You don't. strsep() doesn't allocate memory, it only returns pointers inside the original string. Of course, those are not pointers allocated by malloc() (or similar), so free()ing them is undefined behavior. You only need to free(s) when you are done with the entire string.

Also note that you don't need dynamic memory allocation at all in your example. You can avoid strdup() and free() altogether by simply writing char *s = p;.

try this worked for me :

checkValue(event: any) {
    this.siteSelected.majeur = event;
}

On Google'e Gson library, for having a JsonObject, or more abstract a JsonElement:

import com.google.gson.JsonElement;
import com.google.gson.JsonParser;

JsonElement json = JsonParser.parseReader( new InputStreamReader(new FileInputStream("/someDir/someFile.json"), "UTF-8") );

This is not demanding a given Object structure for receiving/reading the json string.

Having been bitten by this, I have a habit of including locally defined variables in the innermost scope which I use to transfer to any closure. In your example:

foreach (var s in strings)
    query = query.Where(i => i.Prop == s); // access to modified closure

I do:

foreach (var s in strings)
{
    string search = s;
    query = query.Where(i => i.Prop == search); // New definition ensures unique per iteration.
}        

Once you have that habit, you can avoid it in the very rare case you actually intended to bind to the outer scopes. To be honest, I don't think I have ever done so.

The simplest way:

import time

#Your code here
time.sleep(60)
#end of code (and console shut down)

this will leave the code up for 1 minute then close it.

*ngIf removes the element from the DOM when the expression becomes false. You can't have a transition on a non-existing element.

Use instead hidden:

<div class="note" [ngClass]="{'transition':show}" [hidden]="!show">

Implement SQL GROUP BY Feature in Java using Comparator, comparator will compare your column data, and sort it. Basically if you keep sorted data that looks as grouped data, for example if you have same repeated column data then sort mechanism sort them keeping same data one side and then look for other data which is dissimilar data. This indirectly viewed as GROUPING of same data.

public class GroupByFeatureInJava {

    public static void main(String[] args) {
        ProductBean p1 = new ProductBean("P1", 20, new Date());
        ProductBean p2 = new ProductBean("P1", 30, new Date());
        ProductBean p3 = new ProductBean("P2", 20, new Date());
        ProductBean p4 = new ProductBean("P1", 20, new Date());
        ProductBean p5 = new ProductBean("P3", 60, new Date());
        ProductBean p6 = new ProductBean("P1", 20, new Date());

        List<ProductBean> list = new ArrayList<ProductBean>();
        list.add(p1);
        list.add(p2);
        list.add(p3);
        list.add(p4);
        list.add(p5);
        list.add(p6);

        for (Iterator iterator = list.iterator(); iterator.hasNext();) {
            ProductBean bean = (ProductBean) iterator.next();
            System.out.println(bean);
        }
        System.out.println("******** AFTER GROUP BY PRODUCT_ID ******");
        Collections.sort(list, new ProductBean().new CompareByProductID());
        for (Iterator iterator = list.iterator(); iterator.hasNext();) {
            ProductBean bean = (ProductBean) iterator.next();
            System.out.println(bean);
        }

        System.out.println("******** AFTER GROUP BY PRICE ******");
        Collections.sort(list, new ProductBean().new CompareByProductPrice());
        for (Iterator iterator = list.iterator(); iterator.hasNext();) {
            ProductBean bean = (ProductBean) iterator.next();
            System.out.println(bean);
        }
    }
}

class ProductBean {
    String productId;
    int price;

    }
    ProductBean() {
    }
    ProductBean(String productId, int price, Date date) {
        this.productId = productId;
        this.price = price;
        this.date = date;
    }
    class CompareByProductID implements Comparator<ProductBean> {
        public int compare(ProductBean p1, ProductBean p2) {
            if (p1.productId.compareTo(p2.productId) > 0) {
                return 1;
            }
            if (p1.productId.compareTo(p2.productId) < 0) {
                return -1;
            }
            // at this point all a.b,c,d are equal... so return "equal"
            return 0;
        }
        @Override
        public boolean equals(Object obj) {
            // TODO Auto-generated method stub
            return super.equals(obj);
        }
    }

    class CompareByProductPrice implements Comparator<ProductBean> {
        @Override
        public int compare(ProductBean p1, ProductBean p2) {
            // this mean the first column is tied in thee two rows
            if (p1.price > p2.price) {
                return 1;
            }
            if (p1.price < p2.price) {
                return -1;
            }
            return 0;
        }
        public boolean equals(Object obj) {
            // TODO Auto-generated method stub
            return super.equals(obj);
        }
    }

    class CompareByCreateDate implements Comparator<ProductBean> {
        @Override
        public int compare(ProductBean p1, ProductBean p2) {
            if (p1.date.after(p2.date)) {
                return 1;
            }
            if (p1.date.before(p2.date)) {
                return -1;
            }
            return 0;
        }
        @Override
        public boolean equals(Object obj) {
            // TODO Auto-generated method stub
            return super.equals(obj);
        }
    }
}

Output is here for the above ProductBean list is done GROUP BY criteria, here if you see the input data that is given list of ProductBean to Collections.sort(list, object of Comparator for your required column) This will sort based on your comparator implementation and you will be able to see the GROUPED data in below output. Hope this helps...

Yes you can do this.

*[id^='term-']{
    [css here]
}

This will select all ids that start with 'term-'.

As for the reason for not doing this, I see where it would be preferable to select this way; as for style, I wouldn't do it myself, but it's possible.

Try this for multiple text fileds (using class selector):

You can load an assembly using *Assembly.Load** methods. Using Activator.CreateInstance you can create new instances of the type you want. Keep in mind that you have to use the full type name of the class you want to load (for example Namespace.SubNamespace.ClassName). Using the method InvokeMember of the Type class you can invoke methods on the type.

Also, take into account that once loaded, an assembly cannot be unloaded until the whole AppDomain is unloaded too (this is basically a memory leak).

The key checks for FAST REFRESH includes the following:

1) An Oracle materialized view log must be present for each base table.
2) The RowIDs of all the base tables must appear in the SELECT list of the MVIEW query definition.
3) If there are outer joins, unique constraints must be placed on the join columns of the inner table.

No 3 is easy to miss and worth highlighting here

Enums in TypeScript 0.9 are string+number based. You should not need type assertion for simple conversions:

enum Color{
    Red, Green
}

// To String
 var green: string = Color[Color.Green];

// To Enum / number
var color : Color = Color[green];

Try it online

I have documention about this and other Enum patterns in my OSS book : https://basarat.gitbook.io/typescript/type-system/enums

Simplest way is to add this JAVA library using Gradle:

compile 'se.simbio.encryption:library:2.0.0'

You can use it as simple as this:

Encryption encryption = Encryption.getDefault("Key", "Salt", new byte[16]);
String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

Note, you can do:

$results = Project::select('name')->orderBy('name')->get();

This generate a query like:

"SELECT name FROM proyect ORDER BY 'name' ASC"

In some apps when the DB is not optimized and the query is more complex, and you need prevent generate a ORDER BY in the finish SQL, you can do:

$result = Project::select('name')->get();
$result = $result->sortBy('name');
$result = $result->values()->all();

Now is php who order the result.

Use document.location object and its host or hostname properties.

alert(document.location.hostname); // alerts "stackoverflow.com"

That's not possible.

The alternative is using reflection:

 Class.forName("SomeClass").getMethod("someMethod").invoke(null);

Sure! Setup:

>>> import pandas as pd
>>> from random import randint
>>> df = pd.DataFrame({'A': [randint(1, 9) for x in range(10)],
                   'B': [randint(1, 9)*10 for x in range(10)],
                   'C': [randint(1, 9)*100 for x in range(10)]})
>>> df
   A   B    C
0  9  40  300
1  9  70  700
2  5  70  900
3  8  80  900
4  7  50  200
5  9  30  900
6  2  80  700
7  2  80  400
8  5  80  300
9  7  70  800

We can apply column operations and get boolean Series objects:

>>> df["B"] > 50
0    False
1     True
2     True
3     True
4    False
5    False
6     True
7     True
8     True
9     True
Name: B
>>> (df["B"] > 50) & (df["C"] == 900)
0    False
1    False
2     True
3     True
4    False
5    False
6    False
7    False
8    False
9    False

And then we can use these to index into the object. For read access, you can chain indices:

>>> df["A"][(df["B"] > 50) & (df["C"] == 900)]
2    5
3    8
Name: A, dtype: int64

but you can get yourself into trouble because of the difference between a view and a copy doing this for write access. You can use .loc instead:

>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"]
2    5
3    8
Name: A, dtype: int64
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"].values
array([5, 8], dtype=int64)
>>> df.loc[(df["B"] > 50) & (df["C"] == 900), "A"] *= 1000
>>> df
      A   B    C
0     9  40  300
1     9  70  700
2  5000  70  900
3  8000  80  900
4     7  50  200
5     9  30  900
6     2  80  700
7     2  80  400
8     5  80  300
9     7  70  800

Note that I accidentally typed == 900 and not != 900, or ~(df["C"] == 900), but I'm too lazy to fix it. Exercise for the reader. :^)

What matters isn't the attribute but the property, and its value is a boolean.

You can set it using

 document.getElementById("edName").required = true;

This is a bit of an old post, but there is actually a way to do an onclick operator that calls a function instead of going anywhere in ASP.NET

helper.ActionLink("Choose", null, null, null, 
    new {@onclick = "Locations.Choose(" + location.Id + ")", @href="#"})

If you specify empty quotes or the like in the controller/action, it'll likely add a link to what you listed. You can do that, and do a return false in the onclick. You can read more about that at:

What's the effect of adding 'return false' to a click event listener?

If you're doing this onclick in an cshtml file, it'd be a bit cleaner to just specify the link yourself (a href...) instead of having the ActionLink handle it. If you're doing an HtmlHelper, like my example above is coming from, then I'd argue that calling ActionLink is an okay solution, or potentially better, is to use tagbuilder instead.

INSERT INTO ... ON DUPLICATE KEY UPDATE will only work for MYSQL, not for SQL Server.

for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE

Like this:

declare @Source table
(
name varchar(30),
age decimal(23,0)
)

insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);


MERGE beautiful  AS Tg
using  @source as Sc
on tg.namet=sc.name 

when matched then update 
set tg.age=sc.age

when not matched then 
insert (name, age) VALUES
(SC.name, sc.age);

We can find these by looking at Bootstrap's stylesheet, Bootstrap.css. Each \{number} represents a hexadecimal value, so \2a is equal to 0x2a or *.

I can't comment yet, but I think sj26 answer should be the top answer. Just a hint:

Rails.application.eager_load! unless Rails.configuration.cache_classes
ActiveRecord::Base.descendants

Vivek's answer has worked for me, but resulted in an expression has changed after it was checked error. None of the comments worked for me, but what I did was change the change detection strategy.

import {  Component, ChangeDetectionStrategy } from '@angular/core';
@Component({
  changeDetection: ChangeDetectionStrategy.OnPush,
  selector: 'page1',
  templateUrl: 'page1.html',
})

You override $today in the if statement.

if($dd<10){$dd='0'+dd} if($mm<10){$mm='0'+$mm} $today = $dd+'/'+$mm+'/'+$yyyy;

It is then not a Date() object anymore - hence the error.

You can use

<li ng-repeat="(name, age) in items">{{name}}: {{age}}</li>

See ngRepeat documentation. Example: http://jsfiddle.net/WRtqV/1/

The easiest way:

python 2

import urllib2, ssl

request = urllib2.Request('https://somedomain.co/')
response = urllib2.urlopen(request, context=ssl._create_unverified_context())

python 3

from urllib.request import urlopen
import ssl

response = urlopen('https://somedomain.co', context=ssl._create_unverified_context())

All previous answers are correct but were not sufficient for me on ArchLinux. I also needed to edit /etc/php/php.ini and to uncomment :

;extension=gd.so 

The initial ; on the line needs to be removed. After restarting Nginx via systemctl restart nginx, I was good to go.

This appears to fit what you are looking for: https://forums.oracle.com/forums/thread.jspa?threadID=2140801

Basically, you will need to use regular expressions as there appears to be nothing built into oracle for this.

I pulled out the example from the thread and converted it for your purposes. I suck at regex's, though, so that might need tweaked :)

SELECT  *
FROM myTable m
WHERE NOT regexp_like(m.status,'((Done^|Finished except^|In Progress^)')

you can use this too

.parent:hover * {
   /* ... */
}

My solution was to select the maven profiles I had defined in my pom.xml in which I had declared the hibernate dependencies.

CTRL + ALT + P in eclipse.

In my project I was experiencing this problem and many others because in my pom I have different profiles for supporting Glassfish 3, Glassfish 4 and also WildFly so I have differet versions of Hibernate per container as well as different Java compilation targets and so on. Selecting the active maven profiles resolved my issue.

I simply do this in html:

<script>
    $(document).load(function () {
        d = new Date();
        $('#<%= imgpreview.ClientID %>').attr('src','');
    });
</script>

And reload the image in code behind like this:

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        image.Src = "/image.jpg"; //url caming from database
    }

}

Simply use mysql_fetch_assoc and count the array using count() function

If you see the man page of logger:

$ man logger

LOGGER(1) BSD General Commands Manual LOGGER(1)

NAME logger — a shell command interface to the syslog(3) system log module

SYNOPSIS logger [-isd] [-f file] [-p pri] [-t tag] [-u socket] [message ...]

DESCRIPTION Logger makes entries in the system log. It provides a shell command interface to the syslog(3) system log module.

It Clearly says that it will log to system log. If you want to log to file, you can use ">>" to redirect to log file.

Something like this:

import matplotlib.pyplot as plt
... code for plot 1 ...
plt.show()
... code for plot 2...
plt.show()

Note that this will also work if you are using the seaborn package for plotting:

import matplotlib.pyplot as plt
import seaborn as sns
sns.barplot(... code for plot 1 ...) # plot 1
plt.show()
sns.barplot(... code for plot 2 ...) # plot 2
plt.show()

Are you using an error handler? If you're ignoring errors and try to name a sheet the same as an existing sheet or a name with invalid characters, it could be just skipping over that line. See the CleanSheetName function here

http://www.dailydoseofexcel.com/archives/2005/01/04/naming-a-sheet-based-on-a-cell/

for a list of invalid characters that you may want to check for.

Update

Other things to try: Fully qualified references, throwing in a Doevents, code cleaning. This code qualifies your Sheets reference to ThisWorkbook (you can change it to ActiveWorkbook if that suits). It also adds a thousand DoEvents (stupid overkill, but if something's taking a while to get done, this will allow it to - you may only need one DoEvents if this actually fixes anything).

Dim WS As Worksheet
Dim i As Long

With ThisWorkbook
    Set WS = .Worksheets.Add(After:=.Sheets(.Sheets.Count))
End With

For i = 1 To 1000
    DoEvents
Next i

WS.Name = txtSheetName.Value

Finally, whenever I have a goofy VBA problem that just doesn't make sense, I use Rob Bovey's CodeCleaner. It's an add-in that exports all of your modules to text files then re-imports them. You can do it manually too. This process cleans out any corrupted p-code that's hanging around.

As of Rails 4.2, you can use the config.x property:

# config/application.rb (or config/custom.rb if you prefer)
config.x.colours.options = %w[white blue black red green]
config.x.colours.default = 'white'

Which will be available as:

Rails.configuration.x.colours.options
# => ["white", "blue", "black", "red", "green"]
Rails.configuration.x.colours.default
# => "white"

Another method of loading custom config:

# config/colours.yml
default: &default
  options:
    - white
    - blue
    - black
    - red
    - green
  default: white
development:
  *default
production:
  *default

# config/application.rb
config.colours = config_for(:colours)

Rails.configuration.colours
# => {"options"=>["white", "blue", "black", "red", "green"], "default"=>"white"}
Rails.configuration.colours['default']
# => "white"

In Rails 5 & 6, you can use the configuration object directly for custom configuration, in addition to config.x. However, it can only be used for non-nested configuration:

# config/application.rb
config.colours = %w[white blue black red green]

It will be available as:

Rails.configuration.colours
# => ["white", "blue", "black", "red", "green"]

Look here for the answer by TheMattster. I implemented it and it worked like a charm. In a nutshell, his solution suggests to add the COM dll as a resource to the project (so now it compiles into the project's dll), and upon the first run write it to a file (i.e. the dll file I wanted there in the first place).

The following is taken from his answer.

Step 1) Add the DLL as a resource (below as "Resources.DllFile"). To do this open project properties, select the resources tab, select "add existing file" and add the DLL as a resource.

Step 2) Add the name of the DLL as a string resource (below as "Resources.DllName").

Step 3) Add this code to your main form-load:

if (!File.Exists(Properties.Resources.DllName))
{
    var outStream = new StreamWriter(Properties.Resources.DllName, false);
    var binStream = new BinaryWriter(outStream.BaseStream);
    binStream.Write(Properties.Resources.DllFile);
    binStream.Close();
}

My problem was that not only I had to use the COM dll in my project, I also had to deploy it with my app using ClickOnce, and without being able to add reference to it in my project the above solution is practically the only one that worked.

one can resize an UIImage this way

image = [UIImage imageWithCGImage:[image CGImage] scale:2.0 orientation:UIImageOrientationUp];

What worked for me was to add the file under My Project/Java Resources/src and then use

this.getClass().getClassLoader().getResourceAsStream("myfile.txt");

I didn't need to explicitly add this file to the path (adding it to /src does that apparently)

I know this has already been answered, but I wanted to share a potentially better looking way to call Popen via the use of from x import x and functions:

from subprocess import PIPE, Popen


def cmdline(command):
    process = Popen(
        args=command,
        stdout=PIPE,
        shell=True
    )
    return process.communicate()[0]

print cmdline("cat /etc/services")
print cmdline('ls')
print cmdline('rpm -qa | grep "php"')
print cmdline('nslookup google.com')

You can use the extension method below:

public static string GetStringBetween(this string token, string first, string second)
    {            
        if (!token.Contains(first)) return "";

        var afterFirst = token.Split(new[] { first }, StringSplitOptions.None)[1];

        if (!afterFirst.Contains(second)) return "";

        var result = afterFirst.Split(new[] { second }, StringSplitOptions.None)[0];

        return result;
    }

Usage is:

var token = "super exemple of string key : text I want to keep - end of my string";
var keyValue = token.GetStringBetween("key : ", " - ");

This worked for me:

    file = open('docs/my_messy_doc.pdf', 'rb')

Found in declarations, to much confusion:

NON_ZERO_BYTE         Fixed(8)  Constant('79'X),

Found later:

IF WORK_AREA(INDEX) = ZERO_BYTE THEN  /* found zero byte */ 
   WORK_AREA(INDEX) = NON_ZERO_BYTE ; /* reset to nonzero*/

after some test: If you send an email to an outlook client, and the subject is >77 chars, and it needs to use "=?ISO" inside the subject (in my case because of accents) then OutLook will "cut" the subject in the middle of it and mesh it all that comes after, including body text, attaches, etc... all a mesh!

I have several examples like this one:

Subject: =?ISO-8859-1?Q?Actas de la obra N=BA.20100154 (Expediente N=BA.20100182) "NUEVA RED FERROVIARIA.=

TRAMO=20BEASAIN=20OESTE(Pedido=20PC10/00123-125),=20BEASAIN".?=

To:

As you see, in the subject line it cutted on char 78 with a "=" followed by 2 or 3 line feeds, then continued with the rest of the subject baddly.

It was reported to me from several customers who all where using OutLook, other email clients deal with those subjects ok.

If you have no ISO on it, it doesn't hurt, but if you add it to your subject to be nice to RFC, then you get this surprise from OutLook. Bit if you don't add the ISOs, then iPhone email will not understand it(and attach files with names using such characters will not work on iPhones).

I'm not aware of anything like a single table that lets you compare all of them in at one glance (I'm not sure such a table would even be feasible).

Of course the ISO standard document enumerates the complexity requirements in detail, sometimes in various rather readable tables, other times in less readable bullet points for each specific method.

Also the STL library reference at http://www.cplusplus.com/reference/stl/ provides the complexity requirements where appropriate.

That header file is not part of the C++ standard, is therefore non-portable, and should be avoided.

Moreover, even if there were some catch-all header in the standard, you would want to avoid it in lieu of specific headers, since the compiler has to actually read in and parse every included header (including recursively included headers) every single time that translation unit is compiled.

I faced the same problem, it turned out to be VPN related. If you are testing on a device against a corporate network, chances are your Mac has proper VPN set up, but your phone does not. Connect phone to the corporate VPN for your apps deployed to device to see corporate servers.

To include all files and directories:

archive.bulk([
  {
    expand: true,
    cwd: "temp/freewheel-bvi-120",
    src: ["**/*"],
    dot: true
  }
]);

It uses node-glob(https://github.com/isaacs/node-glob) underneath, so any matching expression compatible with that will work.

rm -rf *

Would remove everything (folders & files) in the current directory.

But be careful! Only execute this command if you are absolutely sure, that you are in the right directory.

Try this

 String str="10,692,467,440,017.120".replaceAll(",","");
 BigDecimal bd=new BigDecimal(str);

In C# 3, you can do:

IList<string> l = new List<string> { "test1", "test2", "test3" };

This uses the new collection initializer syntax in C# 3.

In C# 2, I would just use your second option.

i use Mac and i deleted ADT bundle source. faced the same error so i went to project > clean and adb ran normally.

Environ() gets you the value of any environment variable. These can be found by doing the following command in the Command Prompt:

set

If you wanted to get the username, you would do:

Environ("username")

If you wanted to get the fully qualified name, you would do:

Environ("userdomain") & "\" & Environ("username")

This one is correct:

ALTER TABLE `users`
    ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`,
    ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `count`,
    ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `log`;

PHP version > 5.0 has a nice SoapClient integrated. Which doesn't require to parse response xml. Here's a quick example

$client = new SoapClient("http://path.to/wsdl?WSDL");
$res = $client->SoapFunction(array('param1'=>'value','param2'=>'value'));
echo $res->PaymentNotification->payment;

From my experience:

1) If your page has a toggle that uses ng-if/ng-show to show/hide something, ng-if causes more of a browser delay (slower). For example: if you have a button used to toggle between two views, ng-show seems to be faster.

2) ng-if will create/destroy scope when it evaluates to true/false. If you have a controller attached to the ng-if, that controller code will get executed every time the ng-if evaluates to true. If you are using ng-show, the controller code only gets executed once. So if you have a button that toggles between multiple views, using ng-if and ng-show would make a huge difference in how you write your controller code.

Use

void callClass(Class classObject)
{
   //do something with class
}

A Class is also a Java object, so you can refer to it by using its type.

Read more about it from official documentation.

You access the property in the wrong way. With the $this->$my_value = .. syntax, you set the property with the name of the value in $my_value. What you want is $this->my_value = ..

$var = "my_value";
$this->$var = "test";

is the same as

$this->my_value = "test";

To fix a few things from your example, the code below is a better aproach

class my_class {

    public  $my_value = array();

    function __construct ($value) {
        $this->my_value[] = $value;
    }

    function set_value ($value) {
        if (!is_array($value)) {
            throw new Exception("Illegal argument");
        }

        $this->my_value = $value;
    }

    function add_value($value) {
        $this->my_value = $value;
    }
}

$a = new my_class ('a');
$a->my_value[] = 'b';
$a->add_value('c');
$a->set_value(array('d'));

This ensures, that my_value won't change it's type to string or something else when you call set_value. But you can still set the value of my_value direct, because it's public. The final step is, to make my_value private and only access my_value over getter/setter methods

I tested 3 methods to do that...

Method1:

      const FriendCard:any = require('./../pages/FriendCard')

Method2:

      import * as FriendCard from './../pages/FriendCard';

Method3:

if you can find something like this in tsconfig.json:

      { "compilerOptions": { ..., "allowJs": true }

then you can write: import FriendCard from './../pages/FriendCard';

as you write the it with double-quotes, you don't need to escape spaces with \

export PATH=$PATH:"/cygdrive/C/Program Files/Java/jdk1.6.0_23/bin/"

of course this also works:

export PATH=$PATH:/cygdrive/C/Program\ Files/Java/jdk1.6.0_23/bin/

The SpecialCells Does not actually work as it needs to be continuous. I have solved this by adding a sort funtion in order to sort the data based on the coloumns i need.

Sorry for no comments on the code as i was not planning to share it:

Dim oldsheet, scol, ecol, srow, hyesno As String
Dim i, counter As Integer

oldsheet = ActiveSheet.Name


Worksheets(rng.Worksheet.Name).Activate

Worksheets(rng.Worksheet.Name).AutoFilterMode = False

scol = Chr(rng.Column + 64)
ecol = Chr(rng.Columns.Count + rng.Column + 64 - 1)
srow = rng.row

If UBound(fields) - LBound(fields) <> UBound(criterias) - LBound(criterias) Then FilterAndGetData = "Fields&Crit. counts dont match": GoTo done

dd = sortrange(rng, colstoreturn, headers)

For i = LBound(fields) To UBound(fields)
    rng.AutoFilter Field:=CStr(fields(i)), Criteria1:=CStr(criterias(i))
Next i

Dim rngg As Variant

rngg = rng.SpecialCells(xlCellTypeVisible)
Debug.Print ActiveSheet.AutoFilter.range.address
FilterAndGetData = ActiveSheet.AutoFilter.range.SpecialCells(xlCellTypeVisible).Value

    If row.EntireRow.Hidden Then Debug.Print yes
Next row


done:
    'Worksheets("Data").AutoFilterMode = False
    Worksheets(oldsheet).Activate
    If SUset Then Application.ScreenUpdating = True
    If EAset Then Application.EnableEvents = True
    If CMset Then Application.Calculation = xlCalculationAutomatic
End Function
Function sortrange(ByVal rng As Variant, ByVal colnumbers As Variant, ByVal headers As Boolean)

    Dim SUset, EAset, CMset

There are many reasons, but perhaps the most important one is that those functions encourage insecure programming practices because they do not support prepared statements. Prepared statements help prevent SQL injection attacks.

When using mysql_* functions, you have to remember to run user-supplied parameters through mysql_real_escape_string(). If you forget in just one place or if you happen to escape only part of the input, your database may be subject to attack.

Using prepared statements in PDO or mysqli will make it so that these sorts of programming errors are more difficult to make.

You return four variables s1,s2,s3,s4 and receive them using a single variable obj. This is what is called a tuple, obj is associated with 4 values, the values of s1,s2,s3,s4. So, use index as you use in a list to get the value you want, in order.

obj=list_benefits()
print obj[0] + " is a benefit of functions!"
print obj[1] + " is a benefit of functions!"
print obj[2] + " is a benefit of functions!"
print obj[3] + " is a benefit of functions!"

Thanks @Clint for the great answer:

Just wanted to highlight how easy it was to solve this using the Expando Object:

    var dynamicObject = new ExpandoObject() as IDictionary<string, Object>;
    foreach (var property in properties) {
        dynamicObject.Add(property.Key,property.Value);
    }

An other option, you can create your own custom EditText like this :

class CustomEditText : androidx.appcompat.widget.AppCompatEditText {
    constructor(context: Context?) : super(context)
    constructor(context: Context?, attrs: AttributeSet?) : super(context, attrs)
    constructor(context: Context?, attrs: AttributeSet?, defStyleAttr: Int) : super(context, attrs, defStyleAttr)

    private val paint = Paint()
    private val path = Path()

    init { // hide your underbar
        this.setBackgroundResource(android.R.color.transparent)

        // other init stuff...
    }

    override fun onDraw(canvas: Canvas?) {
        super.onDraw(canvas)

        // draw your canvas...
    }
}

This will get you the drives on the machine:

System.IO.DriveInfo.GetDrives()

These two methods will get you the bad characters to check:

System.IO.Path.GetInvalidFileNameChars();
System.IO.Path.GetInvalidPathChars();

I modified @Alisa's code and used cProfile to show why list comprehension is faster:

from functools import reduce
import datetime

def reduce_(numbers):
    return reduce(lambda sum, next: sum + next * next, numbers, 0)

def for_loop(numbers):
    a = []
    for i in numbers:
        a.append(i*2)
    a = sum(a)
    return a

def map_(numbers):
    sqrt = lambda x: x*x
    return sum(map(sqrt, numbers))

def list_comp(numbers):
    return(sum([i*i for i in numbers]))

funcs = [
        reduce_,
        for_loop,
        map_,
        list_comp
        ]

if __name__ == "__main__":
    # [1, 2, 5, 3, 1, 2, 5, 3]
    import cProfile
    for f in funcs:
        print('=' * 25)
        print("Profiling:", f.__name__)
        print('=' * 25)
        pr = cProfile.Profile()
        for i in range(10**6):
            pr.runcall(f, [1, 2, 5, 3, 1, 2, 5, 3])
        pr.create_stats()
        pr.print_stats()

IMHO:

• reduce and map are in general pretty slow. Not only that, using sum on the iterators that map returned is slow, compared to suming a list
• for_loop uses append, which is of course slow to some extent
• list-comprehension not only spent the least time building the list, it also makes sum much quicker, in contrast to map

Ref. @Dave's comment on @Dhiraj's answer; an alternative is to use the callback functionality of the ref attribute on the element being rendered (after a component first renders):

<input ref={ function(component){ React.findDOMNode(component).focus();} } />

Something to note here. We had the same issue with Windows VM's running on an ESXi host. The time sync was turned on in VMWare Tools on the guest, but the guest clocks were consistently off (by about 30 seconds) from the host clock. The ESXi host was configured to get time updates from an internal time server.

It turns out we had the Internet Time setting turned on in the Windows VM's (Control Panel > Date and Time > Internet Time tab) so the guest was getting time updates from two places and the internet time was winning. We turned that off and now the guest clocks are good, getting their time exclusively from the ESXi host.

A POJO is just a plain, old Java Bean with the restrictions removed. Java Beans must meet the following requirements:

1. Default no-arg constructor
2. Follow the Bean convention of getFoo (or isFoo for booleans) and setFoo methods for a mutable attribute named foo; leave off the setFoo if foo is immutable.
3. Must implement java.io.Serializable

POJO does not mandate any of these. It's just what the name says: an object that compiles under JDK can be considered a Plain Old Java Object. No app server, no base classes, no interfaces required to use.

The acronym POJO was a reaction against EJB 2.0, which required several interfaces, extended base classes, and lots of methods just to do simple things. Some people, Rod Johnson and Martin Fowler among them, rebelled against the complexity and sought a way to implement enterprise scale solutions without having to write EJBs.

Martin Fowler coined a new acronym.

Rod Johnson wrote "J2EE Without EJBs", wrote Spring, influenced EJB enough so version 3.1 looks a great deal like Spring and Hibernate, and got a sweet IPO from VMWare out of it.

Here's an example that you can wrap your head around:

public class MyFirstPojo
{
    private String name;

    public static void main(String [] args)
    {
       for (String arg : args)
       {
          MyFirstPojo pojo = new MyFirstPojo(arg);  // Here's how you create a POJO
          System.out.println(pojo); 
       }
    }

    public MyFirstPojo(String name)
    {    
        this.name = name;
    }

    public String getName() { return this.name; } 

    public String toString() { return this.name; } 
}

Assuming you have the array stored in a variable...

foreach($array as $key=>$value) 
{ 
    echo $value;
    if($key != count($array)-1) { echo ", "; }
}

I needed a more flexible solution for working on multiple git repositories so I wrote the following sh code based on 1 and 2. You can use your server address instead of gitlab.com and your port in replace of 22.

SERVER=gitlab.com
PORT=22
nc -z -v -w5 $SERVER $PORT
result1=$?

#Do whatever you want

if [  "$result1" != 0 ]; then
  echo  'port 22 is closed'
else
  echo 'port 22 is open'
fi

It's worked for me:

1. Download SDK from https://cloud.google.com/sdk/docs/install
2. Extract the archive to my home directory (my home is "nintran")
3. Run "./google-cloud-sdk/bin/gcloud init"

I suspect the problem here is that quotes were entered as literals in your string value. You can set these columns to null using:

UPDATE table SET col=NULL WHERE length(col)<3;

You should of course first check that these values are indeed "" with something like:

SELECT DISTINCT(col) FROM table WHERE length(col)<3;

You can use $query->getSingleResult(), which will throw an exception if more than one result are found, or if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L791)

There's also the less famous $query->getOneOrNullResult() which will throw an exception if more than one result are found, and return null if no result is found. (see the related phpdoc here https://github.com/doctrine/doctrine2/blob/master/lib/Doctrine/ORM/AbstractQuery.php#L752)

_{In addition to romkyns's great answer.. here is some relevant documentation/examples.}

DOM Elements have a native .click() method.

The HTMLElement.click() method simulates a mouse click on an element.

When click is used, it also fires the element's click event which will bubble up to elements higher up the document tree (or event chain) and fire their click events too. However, bubbling of a click event will not cause an <a> element to initiate navigation as if a real mouse-click had been received. (mdn reference)

Relevant W3 documentation.

A few examples..

• You can access a specific DOM element from a jQuery object: (example)

    $('a')[0].click();
  

• You can use the .get() method to retrieve a DOM element from a jQuery object: (example)

    $('a').get(0).click();
  

• As expected, you can select the DOM element and call the .click() method. (example)

    document.querySelector('a').click();
  

It's worth pointing out that jQuery is not required to trigger a native .click() event.

Try to add auth method explicitly as below, because sometimes it is required:

session.setConfig("PreferredAuthentications", "password");

Just a few suggestions:

• Screenshots might be an easy way, but you'll have to make sure the code in the image is big enough and clear enough to read. (not the whole screenshot, just the relevant part)
• If you can embed html then there are lots of tools to generate syntax highlighted html.

Unfortunately, as mmyers said, File.list() is about as fast as you are going to get using Java. If speed is as important as you say, you may want to consider doing this particular operation using JNI. You can then tailor your code to your particular situation and filesystem.

Use this query to create the new table with the values from existing table

CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name; 

Now you can get all the values from existing table into newly created table.

I think this is the easiest solution and the updated one:

Do not we have an app which can stream the digital movie from iOS devices like iPhone or iPad to be played on a high definition LED or Plasma TV?

I know of an app air video server which can be used to display content played on computer or laptop on iOS device. But is there any app that can do the reverse & play the digital content from iphone to LED tv .

You can do this in a try and catch block:

        print("null")
except NameError:
    # throw an exception or do something else

As of Node.js v12 (and this is probably fairly stable now, but still marked "experimental"), you have a couple of options for using ESM (ECMAScript Modules) in Node.js (for files, there's a third way for evaling strings), here's what the documentation says:

The --experimental-modules flag can be used to enable support for ECMAScript modules (ES modules).

Once enabled, Node.js will treat the following as ES modules when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .mjs.

• Files ending in .js, or extensionless files, when the nearest parent package.json file contains a top-level field "type" with a value of "module".

• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=module.

Node.js will treat as CommonJS all other forms of input, such as .js files where the nearest parent package.json file contains no top-level "type" field, or string input without the flag --input-type. This behavior is to preserve backward compatibility. However, now that Node.js supports both CommonJS and ES modules, it is best to be explicit whenever possible. Node.js will treat the following as CommonJS when passed to node as the initial input, or when referenced by import statements within ES module code:

• Files ending in .cjs.

• Files ending in .js, or extensionless files, when the nearest parent package.json file contains a top-level field "type" with a value of "commonjs".

• Strings passed in as an argument to --eval or --print, or piped to node via STDIN, with the flag --input-type=commonjs.

The best thing out there is Memory Analyzer (MAT), IntelliJ does not have any bundled heap dump analyzer.

Just for the "I've the shortest one" challenge, here are mines ;)

Iterative:

public static String join(String s, Object... a) {
    StringBuilder o = new StringBuilder();
    for (Iterator<Object> i = Arrays.asList(a).iterator(); i.hasNext();)
        o.append(i.next()).append(i.hasNext() ? s : "");
    return o.toString();
}

Recursive:

public static String join(String s, Object... a) {
    return a.length == 0 ? "" : a[0] + (a.length == 1 ? "" : s + join(s, Arrays.copyOfRange(a, 1, a.length)));
}

Try changing the box-sizing to border-box. The padding is adding to width of your input elements.

See Demo here

CSS

input[type=text],
input[type=password] {
    width: 100%;
    margin-top: 5px;
    height: 25px;
    ...
}

input {
    box-sizing: border-box;
}

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

If you just use round then the two end numbers (1 and 9) will occur less frequently, to get an even distribution of integers between 1 and 9 then:

SELECT MOD(Round(DBMS_RANDOM.Value(1, 99)), 9) + 1 FROM DUAL

The <section> tag defines sections in a document, such as chapters, headers, footers, or any other sections of the document.

whereas:

The <div> tag defines a division or a section in an HTML document.

The <div> tag is used to group block-elements to format them with CSS.

Just for illustration by compare and contrast The code is from http://www.geeksforgeeks.org/g-fact-80/ /The code fails in gcc and passes in g++/

#include<stdio.h>
int initializer(void)
{
    return 50;
}

int main()
{
    int j;
    for (j=0;j<10;j++)
    {
        static int i = initializer();
        /*The variable i is only initialized to one*/
        printf(" value of i = %d ", i);
        i++;
    }
    return 0;
}

How about:

df <- data.frame(matrix(ncol = 3, nrow = 0))
x <- c("name", "age", "gender")
colnames(df) <- x

To do all these operations in one-liner:

setNames(data.frame(matrix(ncol = 3, nrow = 0)), c("name", "age", "gender"))

#[1] name   age    gender
#<0 rows> (or 0-length row.names)

Or

data.frame(matrix(ncol=3,nrow=0, dimnames=list(NULL, c("name", "age", "gender"))))

I found it useful to use a general expression. This way you can do stuff like automatically move focus when input text is valid

<button type="button" moo-focus-expression="form.phone.$valid">

Or automatically focus when the user completes a fixed length field

<button type="submit" moo-focus-expression="smsconfirm.length == 6">

And of course focus after load

<input type="text" moo-focus-expression="true">

The code for the directive:

.directive('mooFocusExpression', function ($timeout) {
    return {
        restrict: 'A',
        link: {
            post: function postLink(scope, element, attrs) {
                scope.$watch(attrs.mooFocusExpression, function (value) {

                    if (attrs.mooFocusExpression) {
                        if (scope.$eval(attrs.mooFocusExpression)) {
                            $timeout(function () {
                                element[0].focus();
                            }, 100); //need some delay to work with ng-disabled
                        }
                    }
                });
            }
        }
    };
});

@742's answer works pretty well, but as outlined in the comments when running from the VS debugger the generic icon is still shown.

If you want to have your icon even when you're pressing F5, you can add in the Main Window:

<Window x:Class="myClass"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Icon="./Resources/Icon/myIcon.png">

where you indicate the path to your icon (the icon can be *.png, *.ico.)

(Note you will still need to set the Application Icon or it'll still be the default in Explorer).

Try something like:

sed 's/[:space:]+/,/g' orig.txt > modified.txt

The character class [:space:] will match all whitespace (spaces, tabs, etc.). If you just want to replace a single character, eg. just space, use that only.

EDIT: Actually [:space:] includes carriage return, so this may not do what you want. The following will replace tabs and spaces.

sed 's/[:blank:]+/,/g' orig.txt > modified.txt

as will

sed 's/[\t ]+/,/g' orig.txt > modified.txt

In all of this, you need to be careful that the items in your file that are separated by whitespace don't contain their own whitespace that you want to keep, eg. two words.

If you wish to escape HTML in a URL:

This is probably NOT what the OP wanted (the question doesn't clearly indicate in which context the escaping is meant to be used), but Python's native library urllib has a method to escape HTML entities that need to be included in a URL safely.

The following is an example:

#!/usr/bin/python
from urllib import quote

x = '+<>^&'
print quote(x) # prints '%2B%3C%3E%5E%26'

I tried to return string from controller but why control returning to error block not in success of ajax

var sownum="aa";
$.ajax({
    type : "POST",
    contentType : 'application/json; charset=utf-8',
    dataType : "JSON",
    url : 'updateSowDetails.html?sownum=' + sownum,
    success : function() {
        alert("Wrong username");
    },
    error : function(request, status, error) {

        var val = request.responseText;
        alert("error"+val);
    }
});

While trying to solve this for myself, I noticed that it's actually possible to retain the scrolling of the page and focus of the input while disabling number changes by attempting to re-fire the caught event on the parent element of the <input type="number"/> on which it was caught, simply like this:

e.target.parentElement.dispatchEvent(e);

However, this causes an error in browser console, and is probably not guaranteed to work everywhere (I only tested on Firefox), since it is intentionally invalid code.

Another solution which works nicely at least on Firefox and Chromium is to temporarily make the <input> element readOnly, like this:

function handleScroll(e) {
  if (e.target.tagName.toLowerCase() === 'input'
    && (e.target.type === 'number')
    && (e.target === document.activeElement)
    && !e.target.readOnly
  ) {
      e.target.readOnly = true;
      setTimeout(function(el){ el.readOnly = false; }, 0, e.target);
  }
}
document.addEventListener('wheel', function(e){ handleScroll(e); });

One side effect that I've noticed is that it may cause the field to flicker for a split-second if you have different styling for readOnly fields, but for my case at least, this doesn't seem to be an issue.

Similarly, (as explained in James' answer) instead of modifying the readOnly property, you can blur() the field and then focus() it back, but again, depending on styles in use, some flickering might occur.

Alternatively, as mentioned in other comments here, you can just call preventDefault() on the event instead. Assuming that you only handle wheel events on number inputs which are in focus and under the mouse cursor (that's what the three conditions above signify), negative impact on user experience would be close to none.

Another possible reason for this error is that you have entire rows duplicated. If that is the case, the problem is solved by removing the duplicate rows.

Wrap them both in a container like so:

.container{ _x000D_
    float:left; _x000D_
    width:100%; _x000D_
}_x000D_
.container div{ _x000D_
    float:left;_x000D_
}

<div class='container'>_x000D_
    <div>_x000D_
        <span>source list</span>_x000D_
        <select size="10">_x000D_
            <option />_x000D_
            <option />_x000D_
            <option />_x000D_
        </select>_x000D_
    </div>_x000D_
    <div>_x000D_
        <span>destination list</span>_x000D_
        <select size="10">_x000D_
            <option />_x000D_
            <option />_x000D_
            <option />_x000D_
        </select>_x000D_
    </div>_x000D_
</div>

If you use bash, then the terminal history is saved in a file called .bash_history. Delete it, and history will be gone.

However, for MySQL the better approach is not to enter the password in the command line. If you just specify the -p option, without a value, then you will be prompted for the password and it won't be logged.

Another option, if you don't want to enter your password every time, is to store it in a my.cnf file. Create a file named ~/.my.cnf with something like:

[client]
user = <username>
password = <password>

Make sure to change the file permissions so that only you can read the file.

Of course, this way your password is still saved in a plaintext file in your home directory, just like it was previously saved in .bash_history.

You should create a new project in Code::Blocks, and make sure it's 'Console Application'.

Add your .cpp files into the project so they are all compiled and linked together.

According to the documentation, there needs to be a top level layout set.

A top level layout is necessary to ensure that your widgets will resize correctly when its window is resized. To check if you have set a top level layout, preview your widget and attempt to resize the window by dragging the size grip.

You can set one by clearing the selection and right clicking on the form itself and choosing one of the layouts available in the context menu.

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

Your FMAT.h requires a definition of std::string in order to complete the definition of class FMAT. In FMAT.cpp, you've done this by #include <string> before #include "FMAT.h". You haven't done that in your main file.

Your attempt to forward declare string was incorrect on two levels. First you need a fully qualified name, std::string. Second this works only for pointers and references, not for variables of the declared type; a forward declaration doesn't give the compiler enough information about what to embed in the class you're defining.

You might take advantage of ruby's "splat" or flattening syntax.

This makes overgrown when clauses — you have about 10 values to test per branch if I understand correctly — a little more readable in my opinion. Additionally, you can modify the values to test at runtime. For example:

honda  = ['honda', 'acura', 'civic', 'element', 'fit', ...]
toyota = ['toyota', 'lexus', 'tercel', 'rx', 'yaris', ...]
...

if include_concept_cars
  honda += ['ev-ster', 'concept c', 'concept s', ...]
  ...
end

case car
when *toyota
  # Do something for Toyota cars
when *honda
  # Do something for Honda cars
...
end

Another common approach would be to use a hash as a dispatch table, with keys for each value of car and values that are some callable object encapsulating the code you wish to execute.

There are already good, detailed answers here, but no visual examples, so here's a quick illustration:

<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<div>This is a div.</div>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>_x000D_
<span>This is a span.</span>

<div> is a block tag, while <span> is an inline tag.

Here is how to do dump the database (with just the schema):

mysqldump -u root -p"passwd" --no-data --add-drop-database --databases my_db_name | sed 's#/[*]!40000 DROP DATABASE IF EXISTS my_db_name;#' >my_db_name.sql

If you also want the data, remove the --no-data option.

The data container is a superfluous workaround. Data-volumes would do the trick for you. Alter your docker-compose.yml to:

version: '2'
services:
  mysql:
    container_name: flask_mysql
    restart: always
    image: mysql:latest
    environment:
      MYSQL_ROOT_PASSWORD: 'test_pass' # TODO: Change this
      MYSQL_USER: 'test'
      MYSQL_PASS: 'pass'
    volumes:
      - my-datavolume:/var/lib/mysql
volumes:
  my-datavolume:

Docker will create the volume for you in the /var/lib/docker/volumes folder. This volume persist as long as you are not typing docker-compose down -v

Your question in somewhat confusing in that that you don't explain what you mean by "current element".

If you have multiple forms on a page with all kinds of input elements and a button of type "submit", then hitting "enter" upon filling any of it's fields will trigger submission of that form. You don't need any Javascript there.

But if you have multiple "submit" buttons on a form and no other inputs (e.g. "edit row" and/or "delete row" buttons in table), then the line you posted could be the way to do it.

Another way (no Javascript needed) could be to give different values to all your buttons (that are of type "submit"). Like this:

<form action="...">
    <input type="hidden" name="rowId" value="...">
    <button type="submit" name="myaction" value="edit">Edit</button>
    <button type="submit" name="myaction" value="delete">Delete</button>
</form>

When you click a button only the form containing the button will be submitted, and only the value of the button you hit will be sent (along other input values).

Then on the server you just read the value of the variable "myaction" and decide what to do.

I tried this as a best guess, but no luck:

It looks right to me. Have you tried setting a message severity explicitly? Also I believe the ID needs to be the same as that of a component (i.e., you'd need to use newPassword1 or newPassword2, if those are your IDs, and not newPassword as you had in the example).

FacesContext.getCurrentInstance().addMessage("newPassword1", 
                    new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error Message"));

Then use <h:message for="newPassword1" /> to display the error message on the JSF page.

Be sure that the place where you adding

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

is right.

You should write it like that in AndroidManifest.xml :

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.project"> 
<uses-permission android:name="android.permission.INTERNET"/>

Dont make my mistakes :)

For Active Directory users, an alternative way to do this would be -- assuming all your groups are stored in OU=Groups,DC=CorpDir,DC=QA,DC=CorpName -- to use the query (&(objectCategory=group)(CN=GroupCN)). This will work well for all groups with less than 1500 members. If you want to list all members of a large AD group, the same query will work, but you'll have to use ranged retrieval to fetch all the members, 1500 records at a time.

The key to performing ranged retrievals is to specify the range in the attributes using this syntax: attribute;range=low-high. So to fetch all members of an AD Group with 3000 members, first run the above query asking for the member;range=0-1499 attribute to be returned, then for the member;range=1500-2999 attribute.

My app has a fragment to loading in 3 secs, but when the fist screen is preparing to show, I press home button and resume run it, it show the same error, so It edit my code and it ran very smooth:

new Handler().post(new Runnable() {
        public void run() {
            if (saveIns == null) {
                mFragment = new Fragment_S1_loading();
                getFragmentManager().beginTransaction()
                        .replace(R.id.container, mFragment).commit();
            }
            getActionBar().hide();
            // Loading screen in 3 secs:
            mCountDownTimerLoading = new CountDownTimer(3000, 1000) {

                @Override
                public void onTick(long millisUntilFinished) {

                }

                @Override
                public void onFinish() {
                    if (saveIns == null) {// TODO bug when start app and press home
                                            // button
                        getFragmentManager()
                                .beginTransaction()
                                .replace(R.id.container,
                                        new Fragment_S2_sesstion1()).commitAllowingStateLoss();
                    }
                    getActionBar().show();
                }
            }.start();
        }
    });

NOTE: add commitAllowingStateLoss() instead of commit()

You should use CSS to align the textbox. The reason your code above does not work is because by default a div's width is the same as the container it's in, therefore in your example it is pushed below.

The following would work.

<td  colspan="2" class="cell">
                <asp:Label ID="Label6" runat="server" Text="Label"></asp:Label>        
                <asp:TextBox ID="TextBox3" runat="server" CssClass="righttextbox"></asp:TextBox>       
</td>

In your CSS file:

.cell
{
text-align:left;
}

.righttextbox
{
float:right;
}

The below code always gives the public IP of the client (and not a private IP behind a proxy).

from flask import request

if request.environ.get('HTTP_X_FORWARDED_FOR') is None:
    print(request.environ['REMOTE_ADDR'])
else:
    print(request.environ['HTTP_X_FORWARDED_FOR']) # if behind a proxy

As I mentioned here Purge Kafka Queue:

Tested in Kafka 0.8.2, for the quick-start example: First, Add one line to server.properties file under config folder:

delete.topic.enable=true

then, you can run this command:

bin/kafka-topics.sh --zookeeper localhost:2181 --delete --topic test

You can use

Response.AddHeader("Content-disposition", "attachment; filename=" + Name);

Check out this example:

http://www.codeproject.com/KB/aspnet/textfile.aspx

This goes for ASP.NET. I am sure you can find similar solutions in all other server side languages. However there's no javascript solution to the best of my knowledge.

When I wanted to use the standard XMLGregorianCalendar for my XML to object marshalling of DateTime in Java, I heard a lot of comments on how heavy weight and cumbersome it was to use it. I was trying to comtrol the XML fields in the xs:datetime structs to manage timezone, milliseconds, etc.

So I designed a utility to build an XMLGregorian calendar from a GregorianCalendar or java.util.Date.

Because of where I work I'm not allowed to share it online without legal, but here's an example of how a client uses it. It abstracts the details and filters some of the implementation of XMLGregorianCalendar that are less used for xs:datetime.

XMLGregorianCalendarBuilder builder = XMLGregorianCalendarBuilder.newInstance(jdkDate);
XMLGregorianCalendar xmlCalendar = builder.excludeMillis().excludeOffset().build();

Granted this pattern is more of a filter as it sets fields in the xmlCalendar as undefined so they are excluded, it still "builds" it. I've easily added other options to the builder to create an xs:date, and xs:time struct and also to manipulate timezone offsets when needed.

If you've ever seen code that creates and uses XMLGregorianCalendar, you would see how this made it much easier to manipulate.

I don't know why but:

#ifdef main
#undef main
#endif

After the includes but before your main should fix it from my experience.

GPS does not need any kind of internet or wireless connection, but there are technologies like A-GPS that use the mobile network to shorten the time to first fix, or the initial positioning or increase the precision in situations when there is a low satellite visibility.

Android phones tend to use A-GPS. If there is no connectivity, they use pure GPS. They do not override the data network mode. If you deactivated it, the phone won't use any data connection (which is handy if you are abroad, and do not want to pay expensive data roaming).

All of these answers unfortunately miss the point.

There are 2 security context nuances here, and we need them to overlap. - "Run as administrator" - changing your execution level on your local machine - "Run as different user" - selects what user credentials you run the process under.

When UAC is enabled on a workstation, there are processes which refuse to run unless elevated - simply being a member of the local "Administrators" group isn't enough. If your requirement also dictates that you use alternate credentials to those you are signed in with, we need a method to invoke the process both as the alternate credentials AND elevated.

What I found can be used, though a bit of a hassle, is:

• run a CMD prompt as administrator

• use the Sysinternals psexec utility as follows:

  psexec \\localworkstation -h -i -u domain\otheruser exetorun.exe

The first elevation is needed to be able to push the psexec service. The -h runs the new "remote" (local) process elevated, and -i lets it interact with the desktop.

Perhaps there are easier ways than this?

From the UIView reference's section about the beginAnimations:context: method:

Use of this method is discouraged in iPhone OS 4.0 and later. You should use the block-based animation methods instead.

Eg of Block-based Animation based on Tom's Comment

[UIView transitionWithView:mysuperview 
                  duration:0.75
                   options:UIViewAnimationTransitionFlipFromRight
                animations:^{ 
                    [myview removeFromSuperview]; 
                } 
                completion:nil];

The pack() method is defined in Window class in Java and it sizes the frame so that all its contents are at or above their preferred sizes.

You can try my implementation of editable combobox http://www.zoonman.com/projects/combobox/

@Id
@GeneratedValue(strategy=GenerationType.AUTO)
private int id;

and you leave it null (0) when persisting. (null if you use the Integer / Long wrappers)

In some cases the AUTO strategy is resolved to SEQUENCE rathen than to IDENTITY or TABLE, so you might want to manually set it to IDENTITY or TABLE (depending on the underlying database).

It seems SEQUENCE + specifying the sequence name worked for you.

As others have said, you need to escape values that include quotes. Here’s a little CSV reader in C? that supports quoted values, including embedded quotes and carriage returns.

By the way, this is unit-tested code. I’m posting it now because this question seems to come up a lot and others may not want an entire library when simple CSV support will do.

You can use it as follows:

using System;
public class test
{
    public static void Main()
    {
        using ( CsvReader reader = new CsvReader( "data.csv" ) )
        {
            foreach( string[] values in reader.RowEnumerator )
            {
                Console.WriteLine( "Row {0} has {1} values.", reader.RowIndex, values.Length );
            }
        }
        Console.ReadLine();
    }
}

Here are the classes. Note that you can use the Csv.Escape function to write valid CSV as well.

using System.IO;
using System.Text.RegularExpressions;

public sealed class CsvReader : System.IDisposable
{
    public CsvReader( string fileName ) : this( new FileStream( fileName, FileMode.Open, FileAccess.Read ) )
    {
    }

    public CsvReader( Stream stream )
    {
        __reader = new StreamReader( stream );
    }

    public System.Collections.IEnumerable RowEnumerator
    {
        get {
            if ( null == __reader )
                throw new System.ApplicationException( "I can't start reading without CSV input." );

            __rowno = 0;
            string sLine;
            string sNextLine;

            while ( null != ( sLine = __reader.ReadLine() ) )
            {
                while ( rexRunOnLine.IsMatch( sLine ) && null != ( sNextLine = __reader.ReadLine() ) )
                    sLine += "\n" + sNextLine;

                __rowno++;
                string[] values = rexCsvSplitter.Split( sLine );

                for ( int i = 0; i < values.Length; i++ )
                    values[i] = Csv.Unescape( values[i] );

                yield return values;
            }

            __reader.Close();
        }
    }

    public long RowIndex { get { return __rowno; } }

    public void Dispose()
    {
        if ( null != __reader ) __reader.Dispose();
    }

    //============================================


    private long __rowno = 0;
    private TextReader __reader;
    private static Regex rexCsvSplitter = new Regex( @",(?=(?:[^""]*""[^""]*"")*(?![^""]*""))" );
    private static Regex rexRunOnLine = new Regex( @"^[^""]*(?:""[^""]*""[^""]*)*""[^""]*$" );
}

public static class Csv
{
    public static string Escape( string s )
    {
        if ( s.Contains( QUOTE ) )
            s = s.Replace( QUOTE, ESCAPED_QUOTE );

        if ( s.IndexOfAny( CHARACTERS_THAT_MUST_BE_QUOTED ) > -1 )
            s = QUOTE + s + QUOTE;

        return s;
    }

    public static string Unescape( string s )
    {
        if ( s.StartsWith( QUOTE ) && s.EndsWith( QUOTE ) )
        {
            s = s.Substring( 1, s.Length - 2 );

            if ( s.Contains( ESCAPED_QUOTE ) )
                s = s.Replace( ESCAPED_QUOTE, QUOTE );
        }

        return s;
    }


    private const string QUOTE = "\"";
    private const string ESCAPED_QUOTE = "\"\"";
    private static char[] CHARACTERS_THAT_MUST_BE_QUOTED = { ',', '"', '\n' };
}

System like Ubuntu prefers to use auth_socket plugin. It will try to authenticate by comparing your username in DB and process which makes mysql request; it is described in here

The socket plugin checks whether the socket user name (the operating system user name) matches the MySQL user name specified by the client program to the server, and permits the connection only if the names match.

Instead you may want to back with the mysql_native_password, which will require user/password to authenticate.

About the method to achieve that, I recommend this instead.

There can be many possible reasons for this failure.

Some are listed above. I faced the same issue, it is very hard to find the root cause of the failure.

I will recommend you to check the session timeout for shh from ssh_config file. Try to increase the session timeout and see if it fails again

use MM(months) instead of mm(minutes) :

DateTime.Now.ToString("dd/MM/yyyy");

check here for more format options.

If you use UPPER(text), the like '%lah%' will always return zero results. Use '%LAH%'.

Add two textfields with Save and Cancel actions and read TextFields text data

func alertWithTF() {

Let me add an example here:

I'm trying to build Alluxio on windows platform and got the same issue, it's because the pom.xml contains below step:

      <plugin>
        <artifactId>exec-maven-plugin</artifactId>
        <groupId>org.codehaus.mojo</groupId>
        <inherited>false</inherited>
        <executions>
          <execution>
            <id>Check that there are no Windows line endings</id>
            <phase>compile</phase>
            <goals>
              <goal>exec</goal>
            </goals>
            <configuration>
              <executable>${build.path}/style/check_no_windows_line_endings.sh</executable>
            </configuration>
          </execution>
        </executions>
      </plugin>

The .sh file is not executable on windows so the error throws.

Comment it out if you do want build Alluxio on windows.
