A worthy note for readability/maintainability:

You can keep the JSONDeserializer:: qualifier with the definition in your implementation file (*.cpp).

As long as your in-class declaration (as mentioned by others) does not have the qualifier, g++/gcc will play nice.

For example:

In myFile.h:

class JSONDeserializer
{
    Value ParseValue(TDR type, const json_string& valueString);
};

And in myFile.cpp:

Value JSONDeserializer::ParseValue(TDR type, const json_string& valueString)
{
    do_something(type, valueString);
}

When myFile.cpp implements methods from many classes, it helps to know who belongs to who, just by looking at the definition.

You're always going to have a loop - someone might come along with a clever one-liner that hides the loop within a call to map() or similar, but it's always going to be there.

My preference would always be to have clean and simple code, unless performance is a major factor.

Here's perhaps a more Pythonic version of your code:

data = [['a','b'], ['a','c'], ['b','d']]
search = 'c'
for sublist in data:
    if sublist[1] == search:
        print "Found it!", sublist
        break
# Prints: Found it! ['a', 'c']

It breaks out of the loop as soon as it finds a match.

(You have a typo, by the way, in ['b''d'].)

Since API 16 you can use the finishAffinity method, which seems to be pretty close to closing all related activities by its name and Javadoc description:

this.finishAffinity();

Finish this activity as well as all activities immediately below it in the current task that have the same affinity. This is typically used when an application can be launched on to another task (such as from an ACTION_VIEW of a content type it understands) and the user has used the up navigation to switch out of the current task and into its own task. In this case, if the user has navigated down into any other activities of the second application, all of those should be removed from the original task as part of the task switch.

Note that this finish does not allow you to deliver results to the previous activity, and an exception will be thrown if you are trying to do so.

Since API 21 you can use a very similar command

finishAndRemoveTask();

Finishes all activities in this task and removes it from the recent tasks list.

A bit late to the party but might be valuable to someone with this error..

I just straight copied a bunch of files into an Xcode project, if you forget to add them to your projects Build Phases you will get the error "Undefined symbols for architecture i386". So add your implementation files to Compile Sources, and Xib files to Copy Bundle Resources.

The error was telling me that there was no link to my classes simply because they weren't included in the Compile Sources, quite obvious really but may save someone a headache.

When I had to solve this problem, I created a hard-coded data dictionary to map between numbers and their associated words. For example, the following might represent a few entries in the dictionary:

{1, "one"}
{2, "two"}
{30, "thirty"}

You really only need to worry about mapping numbers in the 10^0 (1,2,3, etc.) and 10^1 (10,20,30) positions because once you get to 100, you simply have to know when to use words like hundred, thousand, million, etc. in combination with your map. For example, when you have a number like 3,240,123, you get: three million two hundred forty thousand one hundred twenty three.

After you build your map, you need to work through each digit in your number and figure out the appropriate nomenclature to go with it.

You should do something like this:

1) create directory object what would point to server-side accessible folder

CREATE DIRECTORY image_files AS '/data/images'
/

2) Place your file into OS folder directory object points to

3) Give required access privileges to Oracle schema what will load data from file into table:

GRANT READ ON DIRECTORY image_files TO scott
/

4) Use BFILENAME, EMPTY_BLOB functions and DBMS_LOB package (example NOT tested - be care) like in below:

DECLARE
  l_blob BLOB; 
  v_src_loc  BFILE := BFILENAME('IMAGE_FILES', 'myimage.png');
  v_amount   INTEGER;
BEGIN
  INSERT INTO esignatures  
  VALUES (100, 'BOB', empty_blob()) RETURN iblob INTO l_blob; 
  DBMS_LOB.OPEN(v_src_loc, DBMS_LOB.LOB_READONLY);
  v_amount := DBMS_LOB.GETLENGTH(v_src_loc);
  DBMS_LOB.LOADFROMFILE(l_blob, v_src_loc, v_amount);
  DBMS_LOB.CLOSE(v_src_loc);
  COMMIT;
END;
/

After this you get the content of your file in BLOB column and can get it back using Java for example.

edit: One letter left missing: it should be LOADFROMFILE.

For iOS 8, try this:

<a href="sms:/* phone number here */&body=/* body text here */">Link</a>

Switching the ";" with a "&" worked for me.

Code that does what was requested, with examples, and showing how cases he didn't specify are handled:

def format_seconds_to_hhmmss(seconds):
    hours = seconds // (60*60)
    seconds %= (60*60)
    minutes = seconds // 60
    seconds %= 60
    return "%02i:%02i:%02i" % (hours, minutes, seconds)

def format_seconds_to_mmss(seconds):
    minutes = seconds // 60
    seconds %= 60
    return "%02i:%02i" % (minutes, seconds)

minutes = 60
hours = 60*60
assert format_seconds_to_mmss(7*minutes + 30) == "07:30"
assert format_seconds_to_mmss(15*minutes + 30) == "15:30"
assert format_seconds_to_mmss(1000*minutes + 30) == "1000:30"

assert format_seconds_to_hhmmss(2*hours + 15*minutes + 30) == "02:15:30"
assert format_seconds_to_hhmmss(11*hours + 15*minutes + 30) == "11:15:30"
assert format_seconds_to_hhmmss(99*hours + 15*minutes + 30) == "99:15:30"
assert format_seconds_to_hhmmss(500*hours + 15*minutes + 30) == "500:15:30"

You can--and probably should--store this as a timedelta rather than an int, but that's a separate issue and timedelta doesn't actually make this particular task any easier.

Here's a possible solution:

Snippet:

ul {_x000D_
  width: 760px;_x000D_
  margin-bottom: 20px;_x000D_
  overflow: hidden;_x000D_
  border-top: 1px solid #ccc;_x000D_
}_x000D_
li {_x000D_
  line-height: 1.5em;_x000D_
  border-bottom: 1px solid #ccc;_x000D_
  float: left;_x000D_
  display: inline;_x000D_
}_x000D_
#double li {_x000D_
  width: 50%;_x000D_
}

<ul id="double">_x000D_
  <li>first</li>_x000D_
  <li>second</li>_x000D_
  <li>third</li>_x000D_
  <li>fourth</li>_x000D_
</ul>

And it is done.
For 3 columns use li width as 33%, for 4 columns use 25% and so on.

At the time of my writing this answer, the accepted answer to this question appears to state that browsers are not required to delete a cookie when receiving a replacement cookie whose Expires value is in the past. That claim is false. Setting Expires to be in the past is the standard, spec-compliant way of deleting a cookie, and user agents are required by spec to respect it.

Using an Expires attribute in the past to delete a cookie is correct and is the way to remove cookies dictated by the spec. The examples section of RFC 6255 states:

Finally, to remove a cookie, the server returns a Set-Cookie header with an expiration date in the past. The server will be successful in removing the cookie only if the Path and the Domain attribute in the Set-Cookie header match the values used when the cookie was created.

The User Agent Requirements section includes the following requirements, which together have the effect that a cookie must be immediately expunged if the user agent receives a new cookie with the same name whose expiry date is in the past

11. If [when receiving a new cookie] the cookie store contains a cookie with the same name, domain, and path as the newly created cookie:

    1. ...
    2. ...
    3. Update the creation-time of the newly created cookie to match the creation-time of the old-cookie.
    4. Remove the old-cookie from the cookie store.

12. Insert the newly created cookie into the cookie store.

A cookie is "expired" if the cookie has an expiry date in the past.

The user agent MUST evict all expired cookies from the cookie store if, at any time, an expired cookie exists in the cookie store.

Points 11-3, 11-4, and 12 above together mean that when a new cookie is received with the same name, domain, and path, the old cookie must be expunged and replaced with the new cookie. Finally, the point below about expired cookies further dictates that after that is done, the new cookie must also be immediately evicted. The spec offers no wiggle room to browsers on this point; if a browser were to offer the user the option to disable cookie expiration, as the accepted answer suggests some browsers do, then it would be in violation of the spec. (Such a feature would also have little use, and as far as I know it does not exist in any browser.)

Why, then, did the OP of this question observe this approach failing? Though I have not dusted off a copy of Internet Explorer to check its behaviour, I suspect it was because the OP's Expires value was malformed! They used this value:

expires=Thu, Jan 01 1970 00:00:00 UTC;

However, this is syntactically invalid in two ways.

The syntax section of the spec dictates that the value of the Expires attribute must be a

rfc1123-date, defined in [RFC2616], Section 3.3.1

Following the second link above, we find this given as an example of the format:

Sun, 06 Nov 1994 08:49:37 GMT

and find that the syntax definition...

1. requires that dates be written in day month year format, not month day year format as used by the question asker.

   Specifically, it defines rfc1123-date as follows:

   rfc1123-date = wkday "," SP date1 SP time SP "GMT"
   

   and defines date1 like this:

   date1        = 2DIGIT SP month SP 4DIGIT
                ; day month year (e.g., 02 Jun 1982)
   

and

2. doesn't permit UTC as a timezone.

   The spec contains the following statement about what timezone offsets are acceptable in this format:

   All HTTP date/time stamps MUST be represented in Greenwich Mean Time (GMT), without exception.

   What's more if we dig deeper into the original spec of this datetime format, we find that in its initial spec in https://tools.ietf.org/html/rfc822, the Syntax section lists "UT" (meaning "universal time") as a possible value, but does not list not UTC (Coordinated Universal Time) as valid. As far as I know, using "UTC" in this date format has never been valid; it wasn't a valid value when the format was first specified in 1982, and the HTTP spec has adopted a strictly more restrictive version of the format by banning the use of all "zone" values other than "GMT".

If the question asker here had instead used an Expires attribute like this, then:

expires=Thu, 01 Jan 1970 00:00:00 GMT;

then it would presumably have worked.

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

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

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

Yet another cause and solution to this: Check that you didn't put a space in the wrong place, i.e. in parameters; mine was dotnet -c Release - o /home/some/path (note the space between - and o), I kept looking at the path itself, which was correct and threw me off. Hope that helps! (this was in Bash though it should also apply to Windows)

I just realized that the hist documentation is explicit about what to do when you already have an np.histogram

counts, bins = np.histogram(data)
plt.hist(bins[:-1], bins, weights=counts)

The important part here is that your counts are simply the weights. If you do it like that, you don't need the bar function anymore

You can always do

('0' + deg).slice(-2)

See slice():

You can also use negative numbers to select from the end of an array

Hence

('0' + 11).slice(-2) // '11'
('0' + 4).slice(-2)  // '04'

For ease of access, you could of course extract it to a function, or even extend Number with it:

Number.prototype.pad = function(n) {
    return new Array(n).join('0').slice((n || 2) * -1) + this;
}

Which will allow you to write:

c += deg.pad() + '° '; // "04° "

The above function pad accepts an argument specifying the length of the desired string. If no such argument is used, it defaults to 2. You could write:

deg.pad(4) // "0045"

Note the obvious drawback that the value of n cannot be higher than 11, as the string of 0's is currently just 10 characters long. This could of course be given a technical solution, but I did not want to introduce complexity in such a simple function. (Should you elect to, see alex's answer for an excellent approach to that).

Note also that you would not be able to write 2.pad(). It only works with variables. But then, if it's not a variable, you'll always know beforehand how many digits the number consists of.

The 'r' is for reading, 'w' for writing and 'a' is for appending.

The 't' represents text mode as apposed to binary mode.

Several times here on SO I've seen people using rt and wt modes for reading and writing files.

Edit: Are you sure you saw rt and not rb?

These functions generally wrap the fopen function which is described here:

http://www.cplusplus.com/reference/cstdio/fopen/

As you can see it mentions the use of b to open the file in binary mode.

The document link you provided also makes reference to this b mode:

Appending 'b' is useful even on systems that don’t treat binary and text files differently, where it serves as documentation.

I am not sure if the above CSV generation code is so great as it appears to skip th cells and also did not appear to allow for commas in the value. So here is my CSV generation code that might be useful.

It does assume you have the $table variable which is a jQuery object (eg. var $table = $('#yourtable');)

$rows = $table.find('tr');

var csvData = "";

for(var i=0;i<$rows.length;i++){
                var $cells = $($rows[i]).children('th,td'); //header or content cells

                for(var y=0;y<$cells.length;y++){
                    if(y>0){
                      csvData += ",";
                    }
                    var txt = ($($cells[y]).text()).toString().trim();
                    if(txt.indexOf(',')>=0 || txt.indexOf('\"')>=0 || txt.indexOf('\n')>=0){
                        txt = "\"" + txt.replace(/\"/g, "\"\"") + "\"";
                    }
                    csvData += txt;
                }
                csvData += '\n';
 }

You can also disable browser caching with meta HTML tags just put html tags in the head section to avoid the web page to be cached while you are coding/testing and when you are done you can remove the meta tags.

(in the head section)

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0"/>

Refresh your page after pasting this in the head and should refresh the new javascript code too.

This link will give you other options if you need them http://cristian.sulea.net/blog/disable-browser-caching-with-meta-html-tags/

or you can just create a button like so

<button type="button" onclick="location.reload(true)">Refresh</button>

it refreshes and avoid caching but it will be there on your page till you finish testing, then you can take it off. Fist option is best I thing.

Try:

$a1=@(1,2,3,4,5)
$b1=@(1,2,3,4,5,6)
(Compare-Object $a1 $b1).InputObject

Or, you can use:

(Compare-Object $b1 $a1).InputObject

The order doesn't matter.

I love Richard Nienaber's answer, but as Chuu pointed out, it really doesn't tell how to accomplish what Richard is refering to as a solution. Therefore I have chosen to provide you with the way I ended up doing this, ending with the result Richard is talking about.

The solution

In this case I'm creating a greeting widget that needs to know which options it has to greet in. This may be an over-engineered solution to OPs question as I am also creating an container for possible future widgets.

First I set up my collection to handle the different greetings

public class GreetingWidgetCollection : System.Configuration.ConfigurationElementCollection
{
    public List<IGreeting> All { get { return this.Cast<IGreeting>().ToList(); } }

    public GreetingElement this[int index]
    {
        get
        {
            return base.BaseGet(index) as GreetingElement;
        }
        set
        {
            if (base.BaseGet(index) != null)
            {
                base.BaseRemoveAt(index);
            }
            this.BaseAdd(index, value);
        }
    }

    protected override ConfigurationElement CreateNewElement()
    {
        return new GreetingElement();
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return ((GreetingElement)element).Greeting;
    }
}

Then we create the acutal greeting element and it's interface

(You can omit the interface, that's just the way I'm always doing it.)

public interface IGreeting
{
    string Greeting { get; set; }
}

public class GreetingElement : System.Configuration.ConfigurationElement, IGreeting
{
    [ConfigurationProperty("greeting", IsRequired = true)]
    public string Greeting
    {
        get { return (string)this["greeting"]; }
        set { this["greeting"] = value; }
    }
}

The greetingWidget property so our config understands the collection

We define our collection GreetingWidgetCollection as the ConfigurationProperty greetingWidget so that we can use "greetingWidget" as our container in the resulting XML.

public class Widgets : System.Configuration.ConfigurationSection
{
    public static Widgets Widget => ConfigurationManager.GetSection("widgets") as Widgets;

    [ConfigurationProperty("greetingWidget", IsRequired = true)]
    public GreetingWidgetCollection GreetingWidget
    {
        get { return (GreetingWidgetCollection) this["greetingWidget"]; }
        set { this["greetingWidget"] = value; }
    }
}

The resulting XML

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
   <widgets>
       <greetingWidget>
           <add greeting="Hej" />
           <add greeting="Goddag" />
           <add greeting="Hello" />
           ...
           <add greeting="Konnichiwa" />
           <add greeting="Namaskaar" />
       </greetingWidget>
    </widgets>
</configuration>

And you would call it like this

List<GreetingElement> greetings = Widgets.GreetingWidget.All;

I had to use the following with version 1.7.4

@import (less) "foo.css"

I know the accepted answer is @import (css) "foo.css" but it didn't work. If you want to reuse your css class in your new less file, you need to use (less) and not (css).

Check the documentation.

Try this:

<?php /* the php */ ?>
<?php 
    if ($_POST['submit']) {
        // must work
        echo $_POST['contact_list'];
    };
?>


 <?php /* and the html */ ?>

<!doctype html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>teszt</title>
    </head>
    <body>
        <form method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>">
            <textarea id="contact_list" name="contact_list"></textarea>
            <input type="submit" name="submit" value="Send" id="submit"/>
        </form>
    </body>
</html>

sys.stdout.write("%-6s %-50s %-25s\n" % (code, name, industry))

on a side note you can make the width variable with *-s

>>> d = "%-*s%-*s"%(25,"apple",30,"something")
>>> d
'apple                    something                     '

You can find the instructions here. Basically you just add

[global]
http-proxy-host = ip.add.re.ss
http-proxy-port = 3128
http-proxy-compression = no

to your ~/.subversion/servers file.

Using Value2 gives a performance benefit. As per Charles Williams blog

Range.Value2 works the same way as Range.Value, except that it does not check the cell format and convert to Date or Currency. And thats probably why its faster than .Value when retrieving numbers.

So

DirArray = [a1:a5].Value2

Bonus Reading

• Range.Value: Returns or sets a Variant value that represents the value of the specified range.
• Range.Value2: The only difference between this property and the Value property is that the Value2 property doesn't use the Currency and Date data types.

import time
import datetime

# use mktime to step by one day
# end - the last day, numdays - count of days to step back
def gen_dates_list(end, numdays):
  start = end - datetime.timedelta(days=numdays+1)
  end   = int(time.mktime(end.timetuple()))
  start = int(time.mktime(start.timetuple()))
  # 86400 s = 1 day
  return xrange(start, end, 86400)

# if you need reverse the list of dates
for dt in reversed(gen_dates_list(datetime.datetime.today(), 100)):
    print datetime.datetime.fromtimestamp(dt).date()

Just use the style float: left in this way:

<p style="float: left"> Lorem Ipsum </p> 
<form style="float: left">
   <input  type='submit'/>
</form>
<p style="float: left"> Lorem Ipsum </p>

print_r($this->session->userdata); 

or

print_r($this->session->all_userdata());

It's old question but just in case someone bump on this tread...

var input = document.getElementById("your_input");
var file = input.value.split("\\");
var fileName = file[file.length-1];

No need for regex, jQuery....

I guess I am coming late, but this info might be useful to anyone I found out something, which might be simple but important. if you use export on a function directly i.e

export const addPost = (id) =>{
  ...
 }

Note while importing you need to wrap it in curly braces i.e. import {addPost} from '../URL';

But when using export default i.e

const addPost = (id) =>{
  ...
 }

export default addPost,

Then you can import without curly braces i.e. import addPost from '../url';

export default addPost

I hope this helps anyone who got confused as me.

Array is not a primitive type, and the arrays belong to different addresses in the C++ memory.

First Way:

In Kotlin we can create a simple extension for view:

fun View.getLocationOnScreen(): Point
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return Point(location[0],location[1])
}

And simply get coordinates:

val location = yourView.getLocationOnScreen()
val absX = location.x
val absY = location.y

Second Way:

The Second way is more simple :

fun View.absX(): Int
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return location[0]
}

fun View.absY(): Int
{
    val location = IntArray(2)
    this.getLocationOnScreen(location)
    return location[1]
}

and simply get absolute X by view.absX() and Y by view.absY()

Most windows users won't have that font on their computers. Also, you can't just submit it to your server and call it using font-face because this isn't a free font...

And last, but not least, answering the question that nobody mentioned yet, Helvetica and Helvetica Neue do not render well on screen unless they have a really big font-size. You'll find a lot of pages using this font, and in all of them you'll see that the top border of a line of text looks wavy and that some letters look taller than others. In my opinion this is the main reason why you shouldn't use it. There are other options for you to use, like Open Sans.

PATH is an environment variable, and can be displayed with the echo command:

echo $PATH

It's a list of paths separated by the colon character ':'

The which command tells you which file gets executed when you run a command:

which lshw

sometimes what you get is a path to a symlink; if you want to trace that link to where the actual executable lives, you can use readlink and feed it the output of which:

readlink -f $(which lshw)

The -f parameter instructs readlink to keep following the symlink recursively.

Here's an example from my machine:

$ which firefox
/usr/bin/firefox

$ readlink -f $(which firefox)
/usr/lib/firefox-3.6.3/firefox.sh

:not selector:

input:not([type]), input[type='text'], input[type='password'] {
    /* style here */
}

Support: in Internet Explorer 9 and higher

Use the following syntax:

  ALTER TABLE your_table
  MODIFY COLUMN column1 datatype,
  MODIFY COLUMN column2 datatype,
  ... ... ... ... ... 
  ... ... ... ... ...

Based on that, your ALTER command should be:

  ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100)

Note that:

1. There are no second brackets around the MODIFY statements.
2. I used two separate MODIFY statements for two separate columns.

This is the standard format of the MODIFY statement for an ALTER command on multiple columns in a MySQL table.

Take a look at the following: http://dev.mysql.com/doc/refman/5.1/en/alter-table.html and Alter multiple columns in a single statement

If your object is myObject, and you want to test to see if it is an NSString, the code would be:

[myObject isKindOfClass:[NSString class]]

Likewise, if you wanted to test myObject for a UIImageView:

[myObject isKindOfClass:[UIImageView class]]

$date= new DateTime($row['your_date']) ;  
echo $date->format('Y-m-d');

Collections class has an efficient method for shuffling, that can be copied, so as not to depend on it:

/**
 * Usage:
 *    int[] array = {1, 2, 3};
 *    Util.shuffle(array);
 */
public class Util {

    private static Random random;

You can use COUNTIFS for multiple criteria,

=1/COUNTIFS(A:A,A2,B:B,B2) and then drag down. You can put as many criteria as you want in there, but it tends to take a lot of time to process.

As a simplification to chrfin's response, since Chrome should be on the run path if installed, you could just call:

Process.Start("chrome.exe", "http://www.YourUrl.com");

This seem to work as expected for me, opening a new tab if Chrome is already open.

I think the $emit function works better for what I think you're asking for. It keeps your component separated from the Vue instance so that it is reusable in many contexts.

// Child component
<template>
  <div id="app">
    <test @click="$emit('test-click')"></test>
  </div>
</template>

Use it in HTML

// Parent component
<test @test-click="testFunction">

Manually creating a folder named 'npm' in the displayed path fixed the problem.

I agree with those who question why vim needs all this 'disaster recovery' stuff when no other text editors bother with it. I don't want vim creating ANY extra files in the edited file's directory when I'm editing it, thank you very much. To that end, I have this in my _vimrc to disable swap files, and move irritating 'backup' files to the Temp dir:

" Uncomment below to prevent 'tilde backup files' (eg. myfile.txt~) from being created
"set nobackup

" Uncomment below to cause 'tilde backup files' to be created in a different dir so as not to clutter up the current file's directory (probably a better idea than disabling them altogether)
set backupdir=C:\Windows\Temp

" Uncomment below to disable 'swap files' (eg. .myfile.txt.swp) from being created
set noswapfile

Rather than editing batch files (which you may have to do for other Ruby gems, e.g. Bundler), it's probably better to do this once, and do it properly.

On Windows, behind my corporate proxy, all I had to do was add the HTTP_PROXY environment variable to my system.

1. Start -> right click Computer -> Properties
2. Choose "Advanced System Settings"
3. Click Advanced -> Environment Variables
4. Create a new System variable named "HTTP_PROXY", and set the Value to your proxy server
5. Reboot or log out and back in again

Depending on your authentication requirements, the HTTP_PROXY value can be as simple as:

http://proxy-server-name

Or more complex as others have pointed out

http://username:password@proxy-server-name:port-number

Color is not data.

The Get.cell technique has flaws.

1. It does not update as soon as the cell color changes, but only when the cell (or the sheet) is recalculated.
2. It does not have sufficient numbers for the millions of colors that are available in modern Excel. See the screenshot and notice how the different intensities of yellow or purple all have the same number.

That does not surprise, since the Get.cell uses an old XML command, i.e. a command from the macro language Excel used before VBA was introduced. At that time, Excel colors were limited to less than 60.

Again: Color is not data.

If you want to color-code your cells, use conditional formatting based on the cell values or based on rules that can be expressed with logical formulas. The logic that leads to conditional formatting can also be used in other places to report on the data, regardless of the color value of the cell.

Honestly, Wikipedia might be the best place to look for an answer to this.

If NP = P, then we can solve very hard problems much faster than we thought we could before. If we solve only one NP-Complete problem in P (polynomial) time, then it can be applied to all other problems in the NP-Complete category.

Two options…

1. Set the format-detection meta tag.

To remove all auto-formatting for telephone numbers, add this to the head of your html document:

<meta name="format-detection" content="telephone=no">

View more Apple-Specific Meta Tag Keys.

Note: If you have phone numbers on the page with these numbers you should manually format them as links:

<a href="tel:+1-555-555-5555">1-555-555-5555</a>

2. Can’t set a meta tag? Want to use css?

Two css options:

Option 1 (better for web pages)

Target links with href values starting with tel by using this css attribute selector:

a[href^="tel"] {
  color: inherit; /* Inherit text color of parent element. */
  text-decoration: none; /* Remove underline. */
  /* Additional css `propery: value;` pairs here */
}

Option 2 (better for html email templates)

Alternatively, you can when you can’t set a meta tag—such as in html email—wrap phone numbers in link/anchor tags (<a href=""></a>) and then target their styles using css similar to the following and adjust the specific properties you need to reset:

a[x-apple-data-detectors] {
  color: inherit !important;
  text-decoration: none !important;
  font-size: inherit !important;
  font-family: inherit !important;
  font-weight: inherit !important;
  line-height: inherit !important;
}

If you want to target specific links, use classes on your links and then update the css selector above to a[x-apple-data-detectors].class-name.

func change(string: inout String) {

    var character: Character = .normal

    enum Character {
        case space

    for i in stride(from: string.count - 1, through: 0, by: -1) {
        // first get index
        let index: String.Index?
        if i != 0 {

        }

        if string[index!] == "\n" {

        } else {

            character = .normal

        }

    }

    // startIndex
    guard string.count > 0 else { return }
    if string[string.startIndex] == "\n" || string[string.startIndex] == " " {
        string.remove(at: string.startIndex)
    }

    // endIndex - here is a little more complicated!
    guard string.count > 0 else { return }
    let index = string.index(before: string.endIndex)
    if string[index] == "\n" || string[index] == " " {
        string.remove(at: index)
    }

}

Probably something like:

ArrayList<DataPoint> myList = new ArrayList<DataPoint>();
//Fill up myList with your Data Points

//Traversal
for(DataPoint myPoint : myList) {
    if(myPoint.getName() != null && myPoint.getName().equals("Michael Hoffmann")) {
        //Process data do whatever you want
        System.out.println("Found it!");
     }
}

The best "opposite" would be to return it to the default value which is:

display: inline

Try this...

<div class="row">
    <div class="col-xs-3">
        Menu
    </div>
    <div class="col-xs-9">
        <div class="row">
          <div class="col-sm-4 col-sm-push-8">
          Right content
          </div>
          <div class="col-sm-8 col-sm-pull-4">
          Content
          </div>
       </div>
    </div>
</div>

Bootply

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 28800
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 28800

At first, wait_timeout = 28800 which is the default value. To change the session value, you need to set the global variable because the session variable is read-only.

SET @@GLOBAL.wait_timeout=300

After you set the global variable, the session variable automatically grabs the value.

SHOW SESSION VARIABLES LIKE "wait_timeout"; -- 300
SHOW GLOBAL VARIABLES LIKE "wait_timeout"; -- 300

Next time when the server restarts, the session variables will be set to the default value i.e. 28800.

P.S. I m using MySQL 5.6.16

By convention, .h files are included by other files, and never compiled directly by themselves. .cpp files are - again, by convention - the roots of the compilation process; they include .h files directly or indirectly, but generally not .cpp files.

try this.. instead of using re i think using split with strip is much better

def my_handle(self):
    sentence = ' hello  apple  '
    ' '.join(x.strip() for x in sentence.split())
#hello apple
    ''.join(x.strip() for x in sentence.split())
#helloapple

Anything that is static is in the class level. You don't have to create instance to access static fields/method. Static variable will be created once when class is loaded.

Instance variables are the variable associated with the object which means that instance variables are created for each object you create. All objects will have separate copy of instance variable for themselves.

In your case, when you declared it as static final, that is only one copy of variable. If you change it from multiple instance, the same variable would be updated (however, you have final variable so it cannot be updated).

In second case, the final int a is also constant , however it is created every time you create an instance of the class where that variable is declared.

Have a look on this Java tutorial for better understanding ,

With java lambdas (available since java 8) you can simply convert javax.swing.filechooser.FileFilter to java.io.FileFilter in one line.

javax.swing.filechooser.FileFilter swingFilter = new FileNameExtensionFilter("jpeg files", "jpeg");
java.io.FileFilter ioFilter = file -> swingFilter.accept(file);
new File("myDirectory").listFiles(ioFilter);

View view =(View) getActivity().findViewById(controlId);
Spinner spinner = (Spinner)view.findViewById(R.id.spinner1);
String valToSet = spinner.getSelectedItem().toString();

To print any amount of lines between printed text use:

print("Hello" + '\n' *insert number of whitespace lines+ "World!")

'\n' can be used to make whitespace, multiplied, it will make multiple whitespace lines.

Excel expects dates and times to be stored as a floating point number whose value depends on the Date1904 setting of the workbook, plus a number format such as "mm/dd/yyyy" or "hh:mm:ss" or "mm/dd/yyyy hh:mm:ss" so that the number is displayed to the user as a date / time.

Using SpreadsheetGear for .NET you can do this: worksheet.Cells["A1"].Value = DateTime.Now;

This will convert the DateTime to a double which is the underlying type which Excel uses for a Date / Time, and then format the cell with a default date and / or time number format automatically depending on the value.

SpreadsheetGear also has IWorkbook.DateTimeToNumber(DateTime) and NumberToDateTime(double) methods which convert from .NET DateTime objects to a double which Excel can use.

I would expect XlsIO to have something similar.

In your php.ini file set your extension directory, e.g:

extension_dir = "C:/php/ext/"

You will see in you PHP folder there is an ext folder with all the dll's and extensions.

There is very simplest way among all these answers.

Simply write following code inside onBackPressed() method.

long back_pressed;

@Override
public void onBackPressed() {
    if (back_pressed + 1000 > System.currentTimeMillis()){
        super.onBackPressed();
    }
    else{
        Toast.makeText(getBaseContext(),
                "Press once again to exit!", Toast.LENGTH_SHORT)
                .show();
    }
    back_pressed = System.currentTimeMillis();
}

You need to define back_pressed object as long in activity.

If your data field is already a DateTime datatype, you don't need to use [DataType(DataType.Date)] for the annotation; just use:

[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]

on the jQuery, use datepicker for you calendar

    $(document).ready(function () {
        $('#StartDate').datepicker();
    });

on your HTML, use EditorFor helper:

    @Html.EditorFor(model => model.StartDate)

For me it works like this

Rotate clockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=1" "path_output_video.mp4"

Rotate counterclockwise

 ffmpeg -i "path_source_video.mp4" -filter:v "transpose=0,transpose=1,transpose=0" -acodec copy "path_output_video.mp4"

Based upon dwanderson's helpful comment, I was able to do this in a Bash one-liner:

conda create --name envpython2 --file <(conda list -n env1 -e )

My badly named env was "env1" and the new one I wish to clone from it is "envpython2".

In some version of numpy there is another imporant difference that you must be aware:

average do not take in account masks, so compute the average over the whole set of data.

mean takes in account masks, so compute the mean only over unmasked values.

g = [1,2,3,55,66,77]
f = np.ma.masked_greater(g,5)

np.average(f)
Out: 34.0

np.mean(f)
Out: 2.0

Regarding the internal structure of a Python long, check sys.int_info (or sys.long_info for Python 2.7).

>>> import sys
>>> sys.int_info
sys.int_info(bits_per_digit=30, sizeof_digit=4)

Python either stores 30 bits into 4 bytes (most 64-bit systems) or 15 bits into 2 bytes (most 32-bit systems). Comparing the actual memory usage with calculated values, I get

>>> import math, sys
>>> a=0
>>> sys.getsizeof(a)
24
>>> a=2**100
>>> sys.getsizeof(a)
40
>>> a=2**1000
>>> sys.getsizeof(a)
160
>>> 24+4*math.ceil(100/30)
40
>>> 24+4*math.ceil(1000/30)
160

There are 24 bytes of overhead for 0 since no bits are stored. The memory requirements for larger values matches the calculated values.

If your numbers are so large that you are concerned about the 6.25% unused bits, you should probably look at the gmpy2 library. The internal representation uses all available bits and computations are significantly faster for large values (say, greater than 100 digits).

All have highlighted almost all major differences between numpy array and python list, I will just brief them out here:

1. Numpy arrays have a fixed size at creation, unlike python lists (which can grow dynamically). Changing the size of ndarray will create a new array and delete the original.

2. The elements in a Numpy array are all required to be of the same data type (we can have the heterogeneous type as well but that will not gonna permit you mathematical operations) and thus will be the same size in memory

3. Numpy arrays are facilitated advances mathematical and other types of operations on large numbers of data. Typically such operations are executed more efficiently and with less code than is possible using pythons build in sequences

Another way to make the parser raise the same exception is the following incorrect clause.

SELECT r.name
FROM roles r
WHERE id IN ( SELECT role_id ,
                     system_user_id
                 FROM role_members m
                 WHERE r.id = m.role_id
                 AND m.system_user_id = intIdSystemUser
             )

The nested SELECT statement in the IN clause returns two columns, which the parser sees as operands, which is technically correct, since the id column matches values from but one column (role_id) in the result returned by the nested select statement, which is expected to return a list.

For sake of completeness, the correct syntax is as follows.

SELECT r.name
FROM roles r
WHERE id IN ( SELECT role_id
                 FROM role_members m
                 WHERE r.id = m.role_id
                 AND m.system_user_id = intIdSystemUser
             )

The stored procedure of which this query is a portion not only parsed, but returned the expected result.

It's not a direct answer on question (its not about Actions), but it also allow you to scroll easily to required element:

element = driver.find_element_by_id('some_id')
element.location_once_scrolled_into_view

This actually intend to return you coordinates (x, y) of element on page, but also scroll down right to target element

DECLARE @v XML = (SELECT * FROM <tablename> FOR XML AUTO)

Insert the above statement at the point where you want to view the table's contents. The table's contents will be rendered as XML in the locals window, or you can add @v to the watches window.

double a = 1.000001;
double b = 0.000001;

System.out.println( a.compareTo(b) );

Returns:

• -1 : 'a' is numerically less than 'b'.

• 0 : 'a' is equal to 'b'.

• 1 : 'a' is greater than 'b'.

Check this sample out from the Highcharts API.

Replace this

return Highcharts.dateFormat('%a %d %b', this.value);

With this

return Highcharts.dateFormat('%a %d %b %H:%M:%S', this.value);

Here is an example of how to use strtok borrowed from MSDN.

And the relevant bits, you need to call it multiple times. The token char* is the part you would stuff into an array (you can figure that part out).

char string[] = "A string\tof ,,tokens\nand some  more tokens";
char seps[]   = " ,\t\n";
char *token;

int main( void )
{
    printf( "Tokens:\n" );
    /* Establish string and get the first token: */
    token = strtok( string, seps );
    while( token != NULL )
    {
        /* While there are tokens in "string" */
        printf( " %s\n", token );
        /* Get next token: */
        token = strtok( NULL, seps );
    }
}

Just a side note for anyone that stumbles onto this same inquiry... My Operating System is 64 bit - so of course I downloaded the 64 bit MySQL driver... however, my Office applications are 32 bit... Once I downloaded the 32 bit version, the error went away and I could move forward.

I know "for" is not what you want, but it's simple and clear:

for x in b:
  a.remove(x)

Or if members of b might not be in a then use:

for x in b:
  if x in a:
    a.remove(x)

The Windows shell (assuming you're using CMD.exe) uses %ProgramFiles% to point to the Program Files folder, no matter where it is. Since the default Windows file opener accounts for environment variables like this, if the program was well-written, it should support this.

Also, it could be worth using relative addresses. If the program you're using is installed correctly, it should already be in the Program Files folder, so you could just refer to the configuration file as .\config_file.txt if its in the same directory as the program, or ..\other_program\config_file.txt if its in a directory different than the other program. This would apply not only on Windows but on almost every modern operating system, and will work properly if you have the "Start In" box properly set, or you run it directly from its folder.

I think the others have answered your second question. As for the first, the "Hello World" of CUDA, I don't think there is a set standard, but personally, I'd recommend a parallel adder (i.e. a programme that sums N integers).

If you look the "reduction" example in the NVIDIA SDK, the superficially simple task can be extended to demonstrate numerous CUDA considerations such as coalesced reads, memory bank conflicts and loop unrolling.

See this presentation for more info:

http://www.gpgpu.org/sc2007/SC07_CUDA_5_Optimization_Harris.pdf

With multiple phones and beacons at the same location, it's going to be difficult to measure proximity with any high degree of accuracy. Try using the Android "b and l bluetooth le scanner" app, to visualize the signal strengths (distance) variations, for multiple beacons, and you'll quickly discover that complex, adaptive algorithms may be required to provide any form of consistent proximity measurement.

You're going to see lots of solutions simply instructing the user to "please hold your phone here", to reduce customer frustration.

JavaScript that allows for syntax checking

JSHint-Eclipse

and autosuggestions for .js files in Eclipse?

1. Use JSDoc more as JSDT has nice support for the standard, so you will get more suggestions for your own code.
2. There is new TernIDE that provide additional hints for .js and AngulatJS .html. Get them together as Anide from http://www.nodeclipse.org/updates/anide/

As Nodeclipse lead, I am always looking for what is available in Eclipse ecosystem. Nodeclipse site has even more links, and I am inviting to collaborate on the JavaScript tools on GitHub

I found the root of this message in my code, which searched and hid or showed nodes (offline). This was my code:

search.addEventListener('keyup', function() {
    for (const node of nodes)
        if (node.innerText.toLowerCase().includes(this.value.toLowerCase()))
            node.classList.remove('hidden');
        else
            node.classList.add('hidden');
});

The performance tab (profiler) shows the event taking about 60 ms:

Now:

search.addEventListener('keyup', function() {
    const nodesToHide = [];
    const nodesToShow = [];
    for (const node of nodes)
        if (node.innerText.toLowerCase().includes(this.value.toLowerCase()))
            nodesToShow.push(node);
        else
            nodesToHide.push(node);

    nodesToHide.forEach(node => node.classList.add('hidden'));
    nodesToShow.forEach(node => node.classList.remove('hidden'));
});

The performance tab (profiler) now shows the event taking about 1 ms:

And I feel that the search works faster now (229 nodes).

For Mac .app bundles, you should install them via cask, if available, as using symlinks can cause issues. You may even get the following warning if you brew linkapps:

Unfortunately brew linkapps cannot behave nicely with e.g. Spotlight using either aliases or symlinks and Homebrew formulae do not build "proper" .app bundles that can be relocated. Instead, please consider using brew cask and migrate formulae using .apps to casks.

For MacVim, you can install with:

brew cask install macvim

You should then be able to launch MacVim like you do any other macOS app, including mvim or open -a MacVim from a terminal session.

UPDATE: A bit of clarification about brew and brew cask. In a nutshell, brew handles software at the unix level, whereas brew cask extends the functionality of brew into the macOS domain for additional functionality such as handling the location of macOS app bundles. Remember that brew is also implemented on Linux so it makes sense to have this division. There are other resources that explain the difference in more detail, such as What is the difference between brew and brew cask? so I won't say much more here.

For the current Spring-Boot Version 1.5.3 the parameter is

spring.resources.static-locations

Update I configured

`spring.resources.static-locations=file:/opt/x/y/z/static``

and expected to get my index.html living in this folder when calling

http://<host>/index.html

This did not work. I had to include the folder name in the URL:

http://<host>/static/index.html

One cannot disable the browser back button functionality. The only thing that can be done is prevent them.

The below JavaScript code needs to be placed in the head section of the page where you don’t want the user to revisit using the back button:

<script>
    function preventBack() {
        window.history.forward();
    }

    setTimeout("preventBack()", 0);
    window.onunload = function() {
        null
    };
</script>

Suppose there are two pages Page1.php and Page2.php and Page1.php redirects to Page2.php.

Hence to prevent user from visiting Page1.php using the back button you will need to place the above script in the head section of Page1.php.

For more information: Reference

BigDecimal no = new BigDecimal(10); //you can add like this also
no = no.add(new BigDecimal(10));
System.out.println(no);

I checked above solutions and found them quite lengthy. It can be accomplished with just one line of code:

currentElement.nextElementSibling.focus();

or

currentElement.previousElementSibling.focus();

here currentElement may be any i.e. document.activeElement or this if current element is in function's context.

I tracked tab and shift-tab events with keydown event Here is a snippet that relies on "JQuery":

let cursorDirection = ''
$(document).keydown(function (e) {
    let key = e.which || e.keyCode;
    if (e.shiftKey) {
        //does not matter if user has pressed tab key or not.
        //If it matters for you then compare it with 9
        cursorDirection = 'prev';
    }
    else if (key == 9) {
        //if tab key is pressed then move next.
        cursorDirection = 'next';
    }
    else {
        cursorDirection == '';
    }
});

once you have cursor direction then you can use nextElementSibling.focus or previousElementSibling.focus methods

For plain html you don't require any npm package or middleware

just use this:

app.get('/', function(req, res) {
    res.sendFile('index.html');
});

I also don't under stand what the "-" means after the 200 140 section of the log

That value corresponds to the referer as described by Joachim. If you see a dash though, that means that there was no referer value to begin with (eg. the user went straight to a specific destination, like if he/she typed a URL in their browser)

That is because is does not exist, since it is bounded to Windows.

Use the standard functions from <stdio.h> instead, such as getc

The suggested ncurses library is good if you want to write console-based GUIs, but I don't think it is what you want.

I tried to resolve with the suggested answer and still ran into some issues...

This was a solution to my problem:

ARG APP_EXE="AppName.exe"
ENV _EXE=${APP_EXE}

# Build a shell script because the ENTRYPOINT command doesn't like using ENV
RUN echo "#!/bin/bash \n mono ${_EXE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh

# Run the generated shell script.
ENTRYPOINT ["./entrypoint.sh"]

Specifically targeting your problem:

RUN echo "#!/bin/bash \n ./greeting --message ${ADDRESSEE}" > ./entrypoint.sh
RUN chmod +x ./entrypoint.sh
ENTRYPOINT ["./entrypoint.sh"]

You can use fit-content value for width.

#wrap {
  width: -moz-fit-content;
  width: -webkit-fit-content;
  width: fit-content;
  margin: auto;   
}

Note: It works only in latest browsers.

Adding php5.ini doesn't work at all. But see the 'Disable FastCGI' section in this article on GoDaddy: http://support.godaddy.com/help/article/5121/changing-your-hosting-accounts-file-extensions

Add these lines to .htaccess files (webroot & website installation directory):

Options +ExecCGI
addhandler x-httpd-php5-cgi .php

It saves me a day! Cheers! Thanks DragonLord!

The easiest way to do this, is using cstdio's printf. Actually, i'm surprised that anyone mentioned printf! anyway, you need to include the library, like this...

#include<cstdio>

int main() {
    double total;
    cin>>total;
    printf("%.2f\n", total);
}

This will print the value of "total" (that's what %, and then ,total does) with 2 floating points (that's what .2f does). And the \n at the end, is just the end of line, and this works with UVa's judge online compiler options, that is:

g++ -lm -lcrypt -O2 -pipe -DONLINE_JUDGE filename.cpp

the code you are trying to run will not run with this compiler options...

In PHPMailer.php, there are lines as below:

echo $e->getMessage()

Just comment these lines and you will be good to go.

If you run into this issue and you have Visual Studio, you can do the following:

Right-click on your branch and select View History:

Right-click on commit you want to go back to. And Revert or Reset as needed.

I know this is way too late to help the OP with his problem, but to all of us who is just encountering this problem, I had solved this issue by removing the constructor with parameters of my Class which was meant to hold the json data.

I know this is an old question, but I got here because I had a similar problem as everyone above. I solved it by just reading a little closer!

I hadn't noticed there were 2 possible system Images I could choose from, one that contained Google APIs and one that didn't (on my laptop the menu was too small for me to read the (with Google APIs) text appended.

It's a stupid thing to miss, but someone else might have a small screen like I did, and miss this :D

I use this. It's short, elegand and easy to understand.

$(document).ready(function() {
    $('a[href$="' + location.pathname + '"]').addClass('active');
});

use a static defaultProps like:

export default class AddAddressComponent extends Component {
    static defaultProps = {
        provinceList: [],
        cityList: []
    }

render() {
   let {provinceList,cityList} = this.props
    if(cityList === undefined || provinceList === undefined){
      console.log('undefined props')
    }
    ...
}

AddAddressComponent.contextTypes = {
  router: React.PropTypes.object.isRequired
}

AddAddressComponent.defaultProps = {
  cityList: [],
  provinceList: [],
}

AddAddressComponent.propTypes = {
  userInfo: React.PropTypes.object,
  cityList: PropTypes.array.isRequired,
  provinceList: PropTypes.array.isRequired,
}

Taken from: https://github.com/facebook/react-native/issues/1772

If you wish to check the types, see how to use PropTypes in treyhakanson's or Ilan Hasanov's answer, or review the many answers in the above link.

One thing you could try is using the following css:

.child-element {
    padding-left: inherit;
    padding-right: inherit;
    position: absolute;
    left: 0;
    right: 0;
}

It lets the child element inherit the padding from the parent, then the child can be positioned to match the parents widht and padding.

Also, I am using box-sizing: border-box; for the elements involved.

I have not tested this in all browsers, but it seems to be working in Chrome, Firefox and IE10.

As per the documentation on the return statement, return may only occur syntactically nested in a function definition. The same is true for yield.

Here is a QuickSort that I wrote for the arrays returned from the GetRows method of ADODB.Recordset.

I find I rarely have need to use getCanonicalPath() but, if given a File with a filename that is in DOS 8.3 format on Windows, such as the java.io.tmpdir System property returns, then this method will return the "full" filename.

This affects:

• All versions of Tomcat starting from 8.5.3 onwards.
• All versions of Netbeans up to 8.1 (It is fixed in Netbeans 8.2).

This is because Netbeans does not 'see' that tomcat is started, although it started just fine.

I have filed Bug #262749 with NetBeans.

Workaround

In the server.xml file, in the Connector element for HTTP/1.1, add the following attribute: server="Apache-Coyote/1.1".

Example:

<Connector
  connectionTimeout="20000"
  port="8080"
  protocol="HTTP/1.1"
  redirectPort="8443"
  server="Apache-Coyote/1.1"
/>

Cause

The reason for that is that prior to 8.5.3, the default was to set the server header as Apache-Coyote/1.1, while since 8.5.3 this default has now been changed to blank. Apparently Netbeans checks on this header.

Maybe in the future we can expect a fix in netbeans addressing this issue.

I was able to trace it back to a change in documentation.

Tomcat 8.5:

"Overrides the Server header for the http response. If set, the value for this attribute overrides any Server header set by a web application. If not set, any value specified by the application is used. If the application does not specify a value then no Server header is set."

Tomcat 8.0:

"Overrides the Server header for the http response. If set, the value for this attribute overrides the Tomcat default and any Server header set by a web application. If not set, any value specified by the application is used. If the application does not specify a value then Apache-Coyote/1.1 is used. Unless you are paranoid, you won't need this feature."

That explains the need for explicitly adding the server attribute since version 8.5.3.

Put sleep. It will work. I have tried. The reason is that the page wasn't loaded yet. Check this question to know how to wait for load - Wait for page load in Selenium

This will match a single non-ASCII character:

[^\x00-\x7F]

This is a valid PCRE (Perl-Compatible Regular Expression).

You can also use the POSIX shorthands:

• [[:ascii:]] - matches a single ASCII char
• [^[:ascii:]] - matches a single non-ASCII char

[^[:print:]] will probably suffice for you.**

• Sample, in MyRecyclerViewAdapter, add method:

  public interface ItemClickListener {
     void onItemClick(View view, int position);
  }
  

• In MainActivity.java

  @Override
  public void onItemClick(View view, int position) {
  Context context=view.getContext();
  Intent intent=new Intent();
  switch (position){
      case 0:
          intent =  new Intent(context, ChildActivity.class);
          context.startActivity(intent);
          break;
     }
  }
  

I stumbled across Android XRef the other day and found it useful, especially since it is backed by OpenGrok which offers insanely awesome and blindingly fast search.

If you have WHM available it is easier.

Log in to WHM.

Go to EasyApache 4 (or whatever version u have) under Software tab.

Under Currently Installed Packages click Customize.

Go to PHP Extensions, in search type "zip" (without quotes),

you should see 3 modules

check all of them,

click blue button few times to finish the process.

This worked for me. Thankfully I've WHM available.

Starting from a byte array you can use the binary package to do the conversions.

For example if you want to read ints :

buf := bytes.NewBuffer(b) // b is []byte
myfirstint, err := binary.ReadVarint(buf)
anotherint, err := binary.ReadVarint(buf)

The same package allows the reading of unsigned int or floats, with the desired byte orders, using the general Read function.

I was scratching my head about this for a while too, and since Dave's explanation is a little hard to understand I'll post my (apparently working) code:

private class TabListener<T extends Fragment> implements ActionBar.TabListener {
    private Fragment mFragment;
    private Activity mActivity;
    private final String mTag;
    private final Class<T> mClass;

    public TabListener(Activity activity, String tag, Class<T> clz) {
        mActivity = activity;
        mTag = tag;
        mClass = clz;
        mFragment=mActivity.getFragmentManager().findFragmentByTag(mTag);
    }

    public void onTabSelected(Tab tab, FragmentTransaction ft) {
        if (mFragment == null) {
            mFragment = Fragment.instantiate(mActivity, mClass.getName());
            ft.replace(android.R.id.content, mFragment, mTag);
        } else {
            if (mFragment.isDetached()) {
                ft.attach(mFragment);
            }
        }
    }

    public void onTabUnselected(Tab tab, FragmentTransaction ft) {
        if (mFragment != null) {
            ft.detach(mFragment);
        }
    }

    public void onTabReselected(Tab tab, FragmentTransaction ft) {
    }
}

As you can see it's pretty much like the Android sample, apart from not detaching in the constructor, and using replace instead of add.

After much headscratching and trial-and-error I found that finding the fragment in the constructor seems to make the double onCreateView problem magically go away (I assume it just ends up being null for onTabSelected when called through the ActionBar.setSelectedNavigationItem() path when saving/restoring state).

For the example given, I prefer the ternary or condition operator (?) for a specific reason: I can clearly see that assigning a is not optional. With a simple example, it's not too hard to scan the if-else block to see that a is assigned in each clause, but imagine several assignments in each clause:

if (i == 0)
{
    a = 10;
    b = 6;
    c = 3;
}
else
{
    a = 5;
    b = 4;
    d = 1;
}

a = (i == 0) ? 10 : 5;
b = (i == 0) ? 6  : 4;
c = (i == 0) ? 3  : 9;
d = (i == 0) ? 12 : 1;

I prefer the latter so that you know you haven't missed an assignment.

I'm currently experimenting with canvas and pixels... I'm finding this logic works out for me better.

1. Use this to calculate the grey-ness ( luma ? )
2. but with both the existing value and the new 'tint' value
3. calculate the difference ( I found I did not need to multiply )

4. add to offset the 'tint' value

   var grey =  (r + g + b) / 3;    
   var grey2 = (new_r + new_g + new_b) / 3;
   
   var dr =  grey - grey2 * 1;    
   var dg =  grey - grey2 * 1    
   var db =  grey - grey2 * 1;  
   
   tint_r = new_r + dr;    
   tint_g = new_g + dg;   
   tint_b = new_b _ db;
   

or something like that...

$( "#btn1" ).click(function() {
 $('#btn2').css('display','none');
});

Perhaps use plt.annotate:

import numpy as np
import matplotlib.pyplot as plt

N = 10
data = np.random.random((N, 4))
labels = ['point{0}'.format(i) for i in range(N)]

plt.subplots_adjust(bottom = 0.1)
plt.scatter(
    data[:, 0], data[:, 1], marker='o', c=data[:, 2], s=data[:, 3] * 1500,
    cmap=plt.get_cmap('Spectral'))

for label, x, y in zip(labels, data[:, 0], data[:, 1]):
    plt.annotate(
        label,
        xy=(x, y), xytext=(-20, 20),
        textcoords='offset points', ha='right', va='bottom',
        bbox=dict(boxstyle='round,pad=0.5', fc='yellow', alpha=0.5),
        arrowprops=dict(arrowstyle = '->', connectionstyle='arc3,rad=0'))

plt.show()

If you actually want a static property of your class, that isn't currently supported in Swift. The current advice is to get around that by using global constants:

let testStr = "test"
let testStrLen = countElements(testStr)

class MyClass {
    func myFunc() {
    }
}

If you want these to be instance properties instead, you can use a lazy stored property for the length -- it will only get evaluated the first time it is accessed, so you won't be computing it over and over.

class MyClass {
    let testStr: String = "test"
    lazy var testStrLen: Int = countElements(self.testStr)

    func myFunc() {
    }
}

I have developed pure XML based word files in the past. I used .NET, but the language should not matter since it's truely XML. It was not the easiest thing to do (had a project that required it a couple years ago.) These do only work in Word 2007 or above - but all you need is Microsoft's white paper that describe what each tag does. You can accomplish all you want with the tags the same way as if you were using Word (of course a little more painful initially.)

COMMAND: python --version && python3 --version

OUTPUT:

Python 2.7.10
Python 3.7.1

ALIAS COMMAND: pyver

OUTPUT:

Python 2.7.10
Python 3.7.1

You can make an alias like "pyver" in your .bashrc file or else using a text accelerator like AText maybe.

don't forget to close and start the terminal window again ;)

(at least if you want to check "npm --version" in the terminal)

sudo npm install npm -g

that did the trick for me, too

In the documentation of the version 4.11.x, says: ` "This method is like _.sortBy except that it allows specifying the sort orders of the iteratees to sort by. If orders is unspecified, all values are sorted in ascending order. Otherwise, specify an order of "desc" for descending or "asc" for ascending sort order of corresponding values." (source https://lodash.com/docs/4.17.10#orderBy)

let sorted = _.orderBy(this.items, ['fieldFoo', 'fieldBar'], ['asc', 'desc'])

If any one having this issue in flutter after adding firebase storage. Do flutter clean and re run it, it will work

I think it has more to do with how Windows is configured as hinted by this response: Java -Xmx Option

Some more testing: I was able to allocate 1300MB on an old Windows XP machine with only 768MB physical RAM (plus virtual memory). On my 2GB RAM machine I can only get 1220MB. On various other corporate machines (with older Windows XP) I was able to get 1400MB. The machine with a 1220MB limit is pretty new (just purchased from Dell), so maybe it has newer (and more bloated) Windows and DLLs (it's running Window XP Pro Version 2002 SP2).

here you go Sir :-)

Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE - 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles.

It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar.

The first one is the JAR of the logmanager module generated during the package phase by jar:jar (because the module has a packaging of type jar). The second one is the assembly generated by assembly:assembly and should contain the classes from the current module and its dependencies (if you used the descriptor jar-with-dependencies).

I get an error when I double-click on the first jar:

Could not find the main class: com.gorkwobble.logmanager.LogManager. Program will exit.

If you applied the suggested configuration of the link posted as reference, you configured the jar plugin to produce an executable artifact, something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <configuration>
      <archive>
        <manifest>
          <addClasspath>true</addClasspath>
          <mainClass>com.gorkwobble.logmanager.LogManager</mainClass>
        </manifest>
      </archive>
    </configuration>
  </plugin>

So logmanager-0.1.0.jar is indeed executable but 1. this is not what you want (because it doesn't have all dependencies) and 2. it doesn't contain com.gorkwobble.logmanager.LogManager (this is what the error is saying, check the content of the jar).

A slightly different error when I double-click the jar-with-dependencies.jar:

Failed to load Main-Class manifest attribute from: C:\EclipseProjects\logmanager\target\logmanager-0.1.0-jar-with-dependencies.jar

Again, if you configured the assembly plugin as suggested, you have something like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
    </configuration>
  </plugin>

With this setup, logmanager-0.1.0-jar-with-dependencies.jar contains the classes from the current module and its dependencies but, according to the error, its META-INF/MANIFEST.MF doesn't contain a Main-Class entry (its likely not the same MANIFEST.MF as in logmanager-0.1.0.jar). The jar is actually not executable, which again is not what you want.

So, my suggestion would be to remove the configuration element from the maven-jar-plugin and to configure the maven-assembly-plugin like this:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-jar-plugin</artifactId>
    <version>2.2</version>
    <!-- nothing here -->
  </plugin>
  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.2-beta-4</version>
    <configuration>
      <descriptorRefs>
        <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive>
        <manifest>
          <mainClass>org.sample.App</mainClass>
        </manifest>
      </archive>
    </configuration>
    <executions>
      <execution>
        <phase>package</phase>
        <goals>
          <goal>single</goal>
        </goals>
      </execution>
    </executions>
  </plugin>

Of course, replace org.sample.App with the class you want to have executed. Little bonus, I've bound assembly:single to the package phase so you don't have to run assembly:assembly anymore. Just run mvn install and the assembly will be produced during the standard build.

So, please update your pom.xml with the configuration given above and run mvn clean install. Then, cd into the target directory and try again:

java -jar logmanager-0.1.0-jar-with-dependencies.jar

If you get an error, please update your question with it and post the content of the META-INF/MANIFEST.MF file and the relevant part of your pom.xml (the plugins configuration parts). Also please post the result of:

java -cp logmanager-0.1.0-jar-with-dependencies.jar com.gorkwobble.logmanager.LogManager

to demonstrate it's working fine on the command line (regardless of what eclipse is saying).

EDIT: For Java 6, you need to configure the maven-compiler-plugin. Add this to your pom.xml:

  <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
      <source>1.6</source>
      <target>1.6</target>
    </configuration>
  </plugin>

You can run below commands.

 ./catalina.sh run

Note: Make sure the port 8080 is open. If not, kill the process that is using 8080 port using sudo kill -9 $(sudo lsof -t -i:8080)

In java scripts there is no input and output functions. So to debug the code console.log() method is used.It is a method for logging. It will be printed under console log (development tools).

Its is not present in IE8 and under until you open IE development tool.

I've compared a few of the methods possible for doing this, including pandas, several numpy methods, and a list comprehension method.

First, let's start with a baseline:

>>> import numpy as np
>>> import operator
>>> import pandas as pd

>>> x = [1, 2, 1, 2]
>>> %time count = np.sum(np.equal(1, x))
>>> print("Count {} using numpy equal with ints".format(count))
CPU times: user 52 µs, sys: 0 ns, total: 52 µs
Wall time: 56 µs
Count 2 using numpy equal with ints

So, our baseline is that the count should be correct 2, and we should take about 50 us.

Now, we try the naive method:

>>> x = ['s', 'b', 's', 'b']
>>> %time count = np.sum(np.equal('s', x))
>>> print("Count {} using numpy equal".format(count))
CPU times: user 145 µs, sys: 24 µs, total: 169 µs
Wall time: 158 µs
Count NotImplemented using numpy equal
/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/ipykernel_launcher.py:1: FutureWarning: elementwise comparison failed; returning scalar instead, but in the future will perform elementwise comparison
  """Entry point for launching an IPython kernel.

And here, we get the wrong answer (NotImplemented != 2), it takes us a long time, and it throws the warning.

So we'll try another naive method:

>>> %time count = np.sum(x == 's')
>>> print("Count {} using ==".format(count))
CPU times: user 46 µs, sys: 1 µs, total: 47 µs
Wall time: 50.1 µs
Count 0 using ==

Again, the wrong answer (0 != 2). This is even more insidious because there's no subsequent warnings (0 can be passed around just like 2).

Now, let's try a list comprehension:

>>> %time count = np.sum([operator.eq(_x, 's') for _x in x])
>>> print("Count {} using list comprehension".format(count))
CPU times: user 55 µs, sys: 1 µs, total: 56 µs
Wall time: 60.3 µs
Count 2 using list comprehension

We get the right answer here, and it's pretty fast!

Another possibility, pandas:

>>> y = pd.Series(x)
>>> %time count = np.sum(y == 's')
>>> print("Count {} using pandas ==".format(count))
CPU times: user 453 µs, sys: 31 µs, total: 484 µs
Wall time: 463 µs
Count 2 using pandas ==

Slow, but correct!

And finally, the option I'm going to use: casting the numpy array to the object type:

>>> x = np.array(['s', 'b', 's', 'b']).astype(object)
>>> %time count = np.sum(np.equal('s', x))
>>> print("Count {} using numpy equal".format(count))
CPU times: user 50 µs, sys: 1 µs, total: 51 µs
Wall time: 55.1 µs
Count 2 using numpy equal

Fast and correct!

How about

SELECT user()

I use this before.MySQL, H2 is OK, I don't know others.

If you try and reference an undeclared variable, an error will be thrown in all JavaScript implementations.

Properties of objects aren't subject to the same conditions. If an object property hasn't been defined, an error won't be thrown if you try and access it. So in this situation you could shorten:

 if (typeof(myObj.some_property) != "undefined" && myObj.some_property != null)

to

if (myObj.some_property != null)

With this in mind, and the fact that global variables are accessible as properties of the global object (window in the case of a browser), you can use the following for global variables:

if (window.some_variable != null) {
    // Do something with some_variable
}

In local scopes, it always useful to make sure variables are declared at the top of your code block, this will save on recurring uses of typeof.

This answer is specific to situations where the objects to be passed has nested class structure. With nested class structure, making it Parcelable or Serializeable is a bit tedious. And, the process of serialising an object is not efficient on Android. Consider the example below,

class Myclass    {
  int a;
  class SubClass    {
       int b;
  }
}

With Google's GSON library, you can directly parse an object into a JSON formatted String and convert it back to the object format after usage. For example,

MyClass src = new MyClass();
Gson gS = new Gson();
String target = gS.toJson(src); // Converts the object to a JSON String

Now you can pass this String across activities as a StringExtra with the activity intent.

Intent i = new Intent(FromActivity.this, ToActivity.class);
i.putExtra("MyObjectAsString", target);

Then in the receiving activity, create the original object from the string representation.

String target = getIntent().getStringExtra("MyObjectAsString");
MyClass src = gS.fromJson(target, MyClass.class); // Converts the JSON String to an Object

It keeps the original classes clean and reusable. Above of all, if these class objects are created from the web as JSON objects, then this solution is very efficient and time saving.

UPDATE

While the above explained method works for most situations, for obvious performance reasons, do not rely on Android's bundled-extra system to pass objects around. There are a number of solutions makes this process flexible and efficient, here are a few. Each has its own pros and cons.

1. Eventbus
2. Otto

Statement s = cd.createStatement();
ResultSet r = s.executeQuery("SELECT COUNT(*) AS rowcount FROM FieldMaster");
r.next();
int count = r.getInt("rowcount");
r.close();
System.out.println("MyTable has " + count + " row(s).");

Sometimes JDBC does not support following method gives Error like `TYPE_FORWARD_ONLY' use this solution

Sqlite does not support in JDBC.

resultSet.last();
size = resultSet.getRow();
resultSet.beforeFirst();

So at that time use this solution.

Thanks..

For Using the_content() functions (for displaying the main content of the page)

$content = get_the_content();

echo substr($content, 0, 100);

For Using the_excerpt() functions (for displaying the excerpt-short content of the page)

$excerpt= get_the_excerpt();

echo substr($excerpt, 0, 100);

I like to use the recursive pattern for this scenario. For example, something like this:

// If config is an array of queries
var config = JSON.parse(queries.querrryArray);   

// Array of results
var results;

processQueries(config);

function processQueries(queries) {
    var searchQuery;

    if (queries.length == 0) {
        // All queries complete
        res.writeHead(200, {'content-type': 'application/json'});
        res.end(JSON.stringify({results: results}));
        return;
    }

    searchQuery = queries.pop();

    search(searchQuery, function(result) {
        results.push(JSON.stringify({result: result}); 
        processQueries();            
    });

}

processQueries is a recursive function that will pull a query element out of an array of queries to process. Then the callback function calls processQueries again when the query is complete. The processQueries knows to end when there are no queries left.

It is easiest to do this using arrays, but it could be modified to work with object key/values I imagine.

Try something like the following example, quoted from the output of IF /? on Windows XP:

IF EXIST filename. (
    del filename.
) ELSE (
    echo filename. missing.
)

You can also check for a missing file with IF NOT EXIST.

The IF command is quite powerful. The output of IF /? will reward careful reading. For that matter, try the /? option on many of the other built-in commands for lots of hidden gems.  

You can have multiple addresses separated by comma

if (cc.indexOf(',') > 0)
    message.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc));   
else
    message.setRecipient(Message.RecipientType.CC, new InternetAddress(cc));

Looks like the answer above was a little incomplete try the following:-

=RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))

Obviously, this is for cell A2...

What this does is uses a combination of Right and Len - Len is the length of a string and in this case, we want to remove all but one from that... clearly, if you wanted the last two characters you'd change the -1 to -2 etc etc etc.

After the length has been determined and the portion of that which is required - then the Right command will display the information you need.

This works well combined with an IF statement - I use this to find out if the last character of a string of text is a specific character and remove it if it is. See, the example below for stripping out commas from the end of a text string...

=IF(RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))=",",LEFT(A2,(LEN(A2)-1)),A2)

Try this:

public void LoadData()
        {
            SqlConnection con = new SqlConnection("Data Source=.;Initial Catalog=Stocks;Integrated Security=True;Pooling=False");
            SqlDataAdapter sda = new SqlDataAdapter("Select * From [Stocks].[dbo].[product]", con);
            DataTable dt = new DataTable();
            sda.Fill(dt);
            DataGridView1.Rows.Clear();

        foreach (DataRow item in dt.Rows)
        {
            int n = DataGridView1.Rows.Add();
            DataGridView1.Rows[n].Cells[0].Value = item["ProductCode"].ToString();
            DataGridView1.Rows[n].Cells[1].Value = item["Productname"].ToString();
            DataGridView1.Rows[n].Cells[2].Value = item["qty"].ToString();                
            if ((bool)item["productstatus"])
            {
                DataGridView1.Rows[n].Cells[3].Value = "Active";
            }
            else
            {
                DataGridView1.Rows[n].Cells[3].Value = "Deactive";
            }

In Swift 4.1 and Xcode 9.4.1

Simple answer is...

//To call function after 5 seconds time
DispatchQueue.main.asyncAfter(deadline: .now() + 5.0) {
//Here call your function
}

I hope this helps someone. Was a real problem for me.

Just delete the bin folder and then then the project recreates all again and it will be working now .

u can use this:

protected void btnConfirm_Click(object sender, EventArgs e)
{
  Response.Redirect("Confirm.aspx");
}

default port of mysql is 3306

default pot of sql server is 1433

Adding to the knowledge base, I got the same error for

if(class_iter->num == *int_iter)

Even though the IDE gave me the correct members for class_iter. Obviously, the problem is that "anything"::iterator doesn't have a member called num so I need to dereference it. Which doesn't work like this:

if(*class_iter->num == *int_iter)

...apparently. I eventually solved it with this:

if((*class_iter)->num == *int_iter)

I hope this helps someone who runs across this question the way I did.

Declare extern int x; in file.h. And define int x; only in one cpp file.cpp.

I really love var_export(). If you like copy/paste-able code, try:

echo '<pre>' . var_export($data, true) . '</pre>';

Or even something like this for color syntax highlighting:

highlight_string("<?php\n\$data =\n" . var_export($data, true) . ";\n?>");

You can do the same with print_r(). For var_dump() you would just need to add the <pre> tags:

echo '<pre>';
var_dump($data);
echo '</pre>';

if you want to custom the error type, a simple thing you can do is to define an error class based on ValueError.

<div class="foo">Foo Bar</div>

and in your CSS file:

.foo {
    background-image: url("images/foo.png");
}

i use this

    NSArray *arr = [NSLocale preferredLanguages];
for (NSString *lan in arr) {
    NSLog(@"%@: %@ %@",lan, [NSLocale canonicalLanguageIdentifierFromString:lan], [[[NSLocale alloc] initWithLocaleIdentifier:lan] displayNameForKey:NSLocaleIdentifier value:lan]);
}

ignore memory leak..

You can use the keyCode of the arrow keys (37, 38, 39 and 40 for left, up, right and down):

$('.selector').keydown(function (e) {
  var arrow = { left: 37, up: 38, right: 39, down: 40 };

  switch (e.which) {
    case arrow.left:
      //..
      break;
    case arrow.up:
      //..
      break;
    case arrow.right:
      //..
      break;
    case arrow.down:
      //..
      break;
  }
});

Check the above example here.

Through this option you can strictly restricted another char with out number.

 inputFormatters: [FilteringTextInputFormatter.digitsOnly],
 keyboardType: TextInputType.number,

For using above option you have to import this

import 'package:flutter/services.dart';

using this kind of option user can not paste char in a textfield

If 0 is your default value, you can just use a simple assignment:

ddlCustomerNumber.SelectedValue = GetCustomerNumberCookie().ToString();

This automatically selects the proper list item, if the DDL contains the value of the cookie. If it doesn't contain it, this call won't change the selection, so it stays at the default selection. If the latter one is the same as value 0, then it's the perfect solution for you.

I use this mechanism quite a lot and find it very handy.

Looks like IE8-IE7 can't understand multiple Google Web Font styles through the same file request using the link tags href.

These two links helped me figure this out:

• See this open Google issue, and look at the comments.
• Also see this StackOverlow Answer Google Web Fonts don't work in IE8

The only way I have gotten it to work in IE7-IE8 is to only have one Google Web Font request. And only have one font style in the href of the link tag:

So normally you would have this, declaring multiple font styles in the same request:

<link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:400,600,300,800,700,400italic" /> 

But in IE7-IE8 add a IE conditional and specify each Google font style separately and it will work:

<!--[if lte IE 8]>
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:400" /> 
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:700" /> 
    <link rel="stylesheet" href="http://fonts.googleapis.com/css?family=Open+Sans:800" />

Hope this can help others!

Crontab files are simply text files and as such can be treated like any other text file. The purpose of the crontab command is to make editing crontab files safer. When edited through this command, the file is checked for errors and only saved if there are none.

crontab [path to file] can be used to specify a crontab stored in a file. Like crontab -e, this will only install the file if it is error free.

Therefore, a script can either directly write cron tab files, or write them to a temporary file and load them with the crontab [path to temp file] command. Writing directly saves having to write a temporary file, but it also avoids the safety check.

Solution to allow Apache 2 to host websites outside of htdocs:

Underneath the "DocumentRoot" directive in httpd.conf, you should see a directory block. Replace this directory block with:

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Allow from all
</Directory> 

REMEMBER NOT TO USE THIS CONFIGURATION IN A REAL ENVIRONMENT

public class Program {
    public static void main(String[] args) {
        String text = "Hello world";
        BufferedWriter output = null;
        try {
            File file = new File("example.txt");
            output = new BufferedWriter(new FileWriter(file));
            output.write(text);
        } catch ( IOException e ) {
            e.printStackTrace();
        } finally {
          if ( output != null ) {
            output.close();
          }
        }
    }
}

If you want a string, then the other answers are fine, but if what you're looking for is the first few letters as characters you can access them as a list:

your_text.chars.take(30)

This method uses a tidyverse package (purrr).

The list:

x <- as.list(mtcars)

Converting it into a data frame (a tibble more specifically):

library(purrr)
map_df(x, ~.x)

I hope this example helps. You ca use the curly braces to make sure you've got everything enclosed in the switcher changer guy (sorry don't know the technical term but the term that precedes the = sign that changes what happens). I think of switch as a more controlled bunch of if () {} else {} statements.

Each time the switch function is the same but the command we supply changes.

do.this <- "T1"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
#########################################################
do.this <- "T2"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)
########################################################
do.this <- "T3"

switch(do.this,
    T1={X <- t(mtcars)
        colSums(mtcars)%*%X
    },
    T2={X <- colMeans(mtcars)
        outer(X, X)
    },
    stop("Enter something that switches me!")
)

Here it is inside a function:

FUN <- function(df, do.this){
    switch(do.this,
        T1={X <- t(df)
            P <- colSums(df)%*%X
        },
        T2={X <- colMeans(df)
            P <- outer(X, X)
        },
        stop("Enter something that switches me!")
    )
    return(P)
}

FUN(mtcars, "T1")
FUN(mtcars, "T2")
FUN(mtcars, "T3")

In the newer version of datatables (version 1.10.7) it seems things have changed. The way to prevent DataTables from automatically sorting by the first column is to set the order option to an empty array.

You just need to add the following parameter to the DataTables options:

"order": [] 

Set up your DataTable as follows in order to override the default setting:

$('#example').dataTable( {
    "order": [],
    // Your other options here...
} );

That will override the default setting of "order": [[ 0, 'asc' ]].

You can find more details regarding the order option here: https://datatables.net/reference/option/order

First things first ,

they are not always equal

    select 'Hello' from dual where 'Hello  ' like 'Hello';

    select 'Hello' from dual where 'Hello  ' =  'Hello';

when things are not always equal , talking about their performance isn't that relevant.

If you are working on strings and only char variables , then you can talk about performance . But don't use like and "=" as being generally interchangeable .

As you would have seen in many posts ( above and other questions) , in cases when they are equal the performance of like is slower owing to pattern matching (collation)

As of September 2016 (VSCode 1.6), this is now officially supported.

Add the following to your settings.json file:

"editor.formatOnSave": true

Private Sub txtBoxBDayHim_KeyPress(ByVal KeyAscii As MSForms.ReturnInteger)
If KeyAscii >= 48 And KeyAscii <= 57 Or KeyAscii = 8 Then 'only numbers and backspace
    If KeyAscii = 8 Then 'if backspace, ignores + "/"
    Else
        If txtBoxBDayHim.TextLength = 10 Then 'limit textbox to 10 characters
        KeyAscii = 0
        Else
            If txtBoxBDayHim.TextLength = 2 Or txtBoxBDayHim.TextLength = 5 Then 'adds / automatically
            txtBoxBDayHim.Text = txtBoxBDayHim.Text + "/"
            End If
        End If
    End If
Else
KeyAscii = 0
End If
End Sub

This works for me. :)

Your code helped me a lot. Thanks!

I'm brazilian and my english is poor, sorry for any mistake.

The 405 response is a "Method not allowed" response. It sounds like your server isn't properly configured to handle CORS preflight requests. You need to do two things:

1) Enable IIS7 to respond to HTTP OPTIONS requests. You are getting the 405 because IIS7 is rejecting the OPTIONS request. I don't know how to do this as I'm not familiar with IIS7, but there are probably others on Stack Overflow who do.

2) Configure your application to respond to CORS preflight requests. You can do this by adding the following two lines underneath the Access-Control-Allow-Origin line in the <customHeaders> section:

<add name="Access-Control-Allow-Methods" value="GET,PUT,POST,DELETE" />
<add name="Access-Control-Allow-Headers" value="Content-Type" />

You may have to add other values to the Access-Control-Allow-Headers section based on what headers your request is asking for. Do you have the sample code for making a request?

You can learn more about CORS and CORS preflight here: http://www.html5rocks.com/en/tutorials/cors/

Set the trigger option of the popover to hover instead of click, which is the default one.

This can be done using either data-* attributes in the markup:

<a id="popover" data-trigger="hover">Popover</a>

Or with an initialization option:

$("#popover").popover({ trigger: "hover" });

Here's a DEMO.

this code works well on my site because it detects whether its ie or not and activates the javascript if it is its below you can check it out live on ie or other browser Just a demo of the if ie javascript in action

<script type="text/javascript">
<!--[if IE]>
window.location.href = "http://yoursite.com/";
<![endif]-->
</script>

Just convert the timestamp in millisec representation. Use getTime() method.

Not product-specific, but the SQL standard provides

SELECT COUNT() FILTER WHERE <condition-1>, COUNT() FILTER WHERE <condition-2>, ... FROM ...

for this purpose. Or something that closely resembles it, I don't know off the top of my hat.

And of course vendors will prefer to stick with their proprietary solutions.

Is this a bug or feature?

Looks like undefined behaviour. I know that, in practice, you can change the default encoding using a command-line property, but I don't think what happens when you do this is defined.

Bug ID: 4153515 on problems setting this property:

This is not a bug. The "file.encoding" property is not required by the J2SE platform specification; it's an internal detail of Sun's implementations and should not be examined or modified by user code. It's also intended to be read-only; it's technically impossible to support the setting of this property to arbitrary values on the command line or at any other time during program execution.

The preferred way to change the default encoding used by the VM and the runtime system is to change the locale of the underlying platform before starting your Java program.

I cringe when I see people setting the encoding on the command line - you don't know what code that is going to affect.

If you do not want to use the default encoding, set the encoding you do want explicitly via the appropriate method/constructor.

I see that you tagged bash, but Perl would also be a good way to do this:

perl -p -e '`chmod 755 $_`' file.txt

You could also apply a regex to make sure you're getting the right files, e.g. to only process .txt files:

perl -p -e 'if(/\.txt$/) `chmod 755 $_`' file.txt

To "preview" what's happening, just replace the backticks with double quotes and prepend print:

perl -p -e 'if(/\.txt$/) print "chmod 755 $_"' file.txt

In the accepted answer, after the:

SET
Table_A.col1 = Table_B.col1,
Table_A.col2 = Table_B.col2

I would add:

OUTPUT deleted.*, inserted.*

What I usually do is putting everything in a roll backed transaction and using the "OUTPUT": in this way I see everything that is about to happen. When I am happy with what I see, I change the ROLLBACK into COMMIT.

I usually need to document what I did, so I use the "results to Text" option when I run the roll-backed query and I save both the script and the result of the OUTPUT. (Of course this is not practical if I changed too many rows)

Alternatively you could replace all the contents in your .htaccess file

Options +FollowSymLinks -Indexes
RewriteEngine On
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

This is a terrible idea, but it does work.

    public enum myEnum
{
    ThisNameWorks,
    ThisNameDoesntWork149141331,// This Name doesn't work
    NeitherDoesThis1849204824// Neither.does.this;
}

class Program
{
    private static unsafe void ChangeString(string original, string replacement)
    {
        if (original.Length < replacement.Length)
            throw new ArgumentException();

        fixed (char* pDst = original)
        fixed (char* pSrc = replacement)
        {
            // Update the length of the original string
            int* lenPtr = (int*)pDst;
            lenPtr[-1] = replacement.Length;

            // Copy the characters

    public static unsafe void Initialize()

Requirements

1. Your enum names must have the same number of characters or more than the string that you want to it to be.

2. Your enum names shouldn't be repeated anywhere, just in case string interning messes things up

Why this is a bad idea (a few reasons)

1. Your enum names become ugly beause of the requirements

2. It relies on you calling the initialization method early enough

3. Unsafe pointers

4. If the internal format of string changes, e.g. if the length field is moved, you're screwed

5. If Enum.ToString() is ever changed so that it returns only a copy, you're screwed

6. Raymond Chen will complain about your use of undocumented features, and how it's your fault that the CLR team couldn't make an optimization to cut run time by 50%, during his next .NET week.

Assuming you are generating a shared library, most probably what happens is that the variant of liblog4cplus.a you are using wasn't compiled with -fPIC. In linux, you can confirm this by extracting the object files from the static library and checking their relocations:

ar -x liblog4cplus.a  
readelf --relocs fileappender.o | egrep '(GOT|PLT|JU?MP_SLOT)'

If the output is empty, then the static library is not position-independent and cannot be used to generate a shared object.

Since the static library contains object code which was already compiled, providing the -fPIC flag won't help.

You need to get ahold of a version of liblog4cplus.a compiled with -fPIC and use that one instead.

Why don't you set both Background & BorderBrush by same brush

 <Style TargetType="{x:Type Button}" >
        <Setter Property="Background" Value="{StaticResource marginBackGround}"></Setter>
        <Setter Property="BorderBrush" Value="{StaticResource marginBackGround}"></Setter>            
 </Style>

<LinearGradientBrush  x:Key="marginBackGround" EndPoint=".5,1" StartPoint="0.5,0">
    <GradientStop Color="#EE82EE" Offset="0"/>
    <GradientStop Color="#7B30B6" Offset="0.5"/>
    <GradientStop Color="#510088" Offset="0.5"/>
    <GradientStop Color="#76209B" Offset="0.9"/>
    <GradientStop Color="#C750B9" Offset="1"/>
</LinearGradientBrush>

$(document).on( "keydown",  keyPressed);

function keyPressed (e){
    e = e || window.e;
    var newchar = e.which || e.keyCode;
    alert(newchar)
}

Another posibility is using intent.getAction:

In Service:

public class SampleService inherits Service{
    static final String ACTION_START = "com.yourcompany.yourapp.SampleService.ACTION_START";
    static final String ACTION_DO_SOMETHING_1 = "com.yourcompany.yourapp.SampleService.DO_SOMETHING_1";
    static final String ACTION_DO_SOMETHING_2 = "com.yourcompany.yourapp.SampleService.DO_SOMETHING_2";
    static final String ACTION_STOP_SERVICE = "com.yourcompany.yourapp.SampleService.STOP_SERVICE";

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        String action = intent.getAction();
        //System.out.println("ACTION: "+action);
        switch (action){
            case ACTION_START:
                startingService(intent.getIntExtra("valueStart",0));
                break;
            case ACTION_DO_SOMETHING_1:
                int value1,value2;
                value1=intent.getIntExtra("value1",0);
                value2=intent.getIntExtra("value2",0);
                doSomething1(value1,value2);
                break;
            case ACTION_DO_SOMETHING_2:
                value1=intent.getIntExtra("value1",0);
                value2=intent.getIntExtra("value2",0);
                doSomething2(value1,value2);
                break;
            case ACTION_STOP_SERVICE:
                stopService();
                break;
        }
        return START_STICKY;
    }

    public void startingService(int value){
        //calling when start
    }

    public void doSomething1(int value1, int value2){
        //...
    }

    public void doSomething2(int value1, int value2){
        //...
    }

    public void stopService(){
        //...destroy/release objects
        stopself();
    }
}

In Activity:

public void startService(int value){
    Intent myIntent = new Intent(SampleService.ACTION_START);
    myIntent.putExtra("valueStart",value);
    startService(myIntent);
}

public void serviceDoSomething1(int value1, int value2){
    Intent myIntent = new Intent(SampleService.ACTION_DO_SOMETHING_1);
    myIntent.putExtra("value1",value1);
    myIntent.putExtra("value2",value2);
    startService(myIntent);
}

public void serviceDoSomething2(int value1, int value2){
    Intent myIntent = new Intent(SampleService.ACTION_DO_SOMETHING_2);
    myIntent.putExtra("value1",value1);
    myIntent.putExtra("value2",value2);
    startService(myIntent);
}

public void endService(){
    Intent myIntent = new Intent(SampleService.STOP_SERVICE);
    startService(myIntent);
}

Finally, In Manifest file:

<service android:name=".SampleService">
    <intent-filter>
        <action android:name="com.yourcompany.yourapp.SampleService.ACTION_START"/>
        <action android:name="com.yourcompany.yourapp.SampleService.DO_SOMETHING_1"/>
        <action android:name="com.yourcompany.yourapp.SampleService.DO_SOMETHING_2"/>
        <action android:name="com.yourcompany.yourapp.SampleService.STOP_SERVICE"/>
    </intent-filter>
</service>

$text='<span style="font-weight: bold;">Foo</span>';
$text=preg_replace( '/<span style="font-weight: bold;">(.*?)<\/span>/', '<strong>$1</strong>',$text);

Note: only work for your example.

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

You mean like length or size()?

Refs: http://api.jquery.com/length/

$(this).parent().parent().attr('id');

Is how you would get the id of the parent's parent.

EDIT:

$(this).closest('ul').attr('id');

Is a more foolproof solution for your case.

Why is 21 the default port for FTP? Or 80 the default for HTTP? It is a convention.

desc keyspaces will do it for you.

I think I know what you are asking for. Here is what you can do.

first get the height of the person say h meters.

if you can calculate the height of the camera from ground (using height if the person i.e. h) and get angles A and B using gyroscope or something from android then you can calculate the height of the object using the above formula.

Isn't this what you were looking for???

let me know if you need any explanation.

If you're wanting to run the script and end at a prompt (so you can inspect variables, etc), then use:

python -i test.py

That will run the script and then drop you into a Python interpreter.

Just leave out the "dot-slash" ./:

D:\Gesture Recognition\Gesture Recognition\Debug>"Gesture Recognition.exe"

Though, if you wanted to, you could use .\ and it would work.

D:\Gesture Recognition\Gesture Recognition\Debug>.\"Gesture Recognition.exe"
